DETTACH / attach in SQL SERVER 2000

DETTACH / attach in SQL SERVER 2000
You probably have done a copy of the database to other location by using a database backup Either attach or detach the database operation. Do you know what precisely Happen behind detach the database under the hood?
Detach the database Could Be done only if the database is not being accessed by anyone. If you Would like to make sure none accesses the database, you cans set the database to sql SINGLE_USER in ALTER DATABASE command with one of the termination options: WITH ROLLBACK AFTER n SECONDS WITH ROLLBACK IMMEDIATE or (Where n is a any integer number), for example:
ALTER DATABASE AdventureWorks2008
SET SINGLE_USER
WITH ROLLBACK AFTER 3 SECONDS
After That you cans sp_detach_db <databasename> issue (for example: EXEC sp_detach_db AdventureWorks2008).
Interesting thing to note Is That Pls detach a database is Issued, SQL Server will of copy dirty pages (pages changes since last checkpoint) back to corresponding pages in database files. You just only need to copy / move files into other database location for attaching the SQL Server database and transaction log files Could rebuild for you. But there are two conditions database That you need to be aware about.
If the database is read only, you need to include not only data files but Also Pls attach the transaction log file database. If the database is read write, you need only to include data files.
Since SQL Server 2005, the syntax for attach database is CREATE DATABASE ON <filespec> <database name> [, .... N] FOR {attach | ATTACH_REBUILD_LOG}. The legacy command sp_attach_db Should not be Used Because it Becomes depreciated features and Could Be removed in future SQL Server releases. The difference Between the new syntax and legacy Is That the maximum number of files on legacy is up to 16 files on the new syntax whereas the maximum number of files That Could be attached is up to 32.767 32.767 files and file groups. Certainly you will from never reach the number of files That need to be attached.
To me, attach-detach is as good as a backup-restore the database. The only difference Between Them Is That database is still accessible During the backup-restore whereas attach-detach requires a database to be offline.
** If my friends do not know what it means can translate on google
Bottom line:
DETTACH / Attach
Function: copying files to a server database and SQL Server menginisilisasi

Java scripts and Java differences

Java scripts and Java differences
First in Class X EMP B (Programs and Classes), Most Hated Banget with that name there are 2 JAVA Karna he thought of Master Patterns Differ in Teaching Us, And We Also confused with Javascript on the Web!
So What is actually "Differences Between Java and Java Script ..?", if both are indeed derived from" Java "...!!. Ga At first I also know what is actually "Differences Between Java Script with Java", due to curious to know eventually I try to ask the same oom Google with the Keyword "The difference with Java Java Script" and after I had been looking for finally met as well. nah these results I found:
1.
Javascript is usually in its use combined with HTML, the aim is to enrich the HTML to get more interactive, java script therefore depend strongly on the browser used. If your browser does not mengijikan (disable) to use a javascript feed applications that use javascript are not the maximum, even could have been an error. Java is a language pemogramam object-oriented programming (OOP) in which applications can be made directly in the execution, of course by doing the compiler first. Language similar to java. Net was Microsoft, but java is open, in contrast with. Net is its use requires a license.
2.
JavaSript just a scripting language, whereas Java programming language that is multifunctional and platform independent. Java can be used to create desktop applications and also server (SDK and EE) is also for programming the mobile (ME), while JavaSript based on client-side can only dijalakan with the browser and executed on the client computer.
In addition, Java can also be used to create desktop applications that run in the browser by using the applet, while JavaScript can only work when combined with HTML.
3.
JavaScript is a script (text) which is read by the browser, then translated into a set of commands. Then the order was executed in the browser. JavaScript (generally) Dlm pasted HTML. Java is a program which generated (compiled) on the server, then run in a browser (if she Java Applet) or run on the server (if he's Java Server Pages).New results are displayed in the browser. Java programs must be retrieved from the server.
So the main difference between Jaca Script with Java is the way a program is executed. With its own java can penggunakaannya broader, JME -> for application development on mobile phones, JDK -> application development on desktops and Jee -> for the development of large applications (enterprise)
How? Are Useful For pal? Easy - Helpful hope ya friend!

CONNECTION TO DATABASE, metadata

2011-05-26T00:48:00.000+07:00

CONNECTION TO DATABASE, metadata
Project for which we can make to a high with the database we have, then we have toconnect your database with an existing project.
Process connection:
a. Registration drivers
b. Connection to the database
c. Both must exist in the instruction block try {} catch (Exception) {}
Class / Interface in use:
Class Class
Method:
static Class forName (String namaclass) à Driver Registration class
Ex:
Class c = Class.forName ("com.jdbc.mysql.Driver");
All classes used for database management, is in the package java.sql .*
Class DriverManager
Method:
Connection getConnection (String location, String username, String pwd)
Ex:
String location = "jdbc: mysql: / / localhost / nama_db";
String uname = "username";
String pwd = "password";
Connection con = DriverManager.getConnection (location, uname, pwd);
À Connection Interface
Exception:
È Class ClassNotFoundException Exception will occur if there is an error registrationclass,
use forName method of class Class.
Class SQLExceptionèException to know the error connection and access the database / table.
Example 1
Create a new project, add the object form with the draft as follows:

In the TEST CONNECTION button to add the following code:

Adding libraries to the project in a way MYSQL, right-click Libraries choose AddLibrary

Selection dialog will appear as follows:

Select the MySQL JDBC Driver, and click the Add Library.
Run.
Example 2.
If the project that we make involve many forms, and each form must connect to the database, it would be better if the connection is made in a separate class so that wedo not need to write the connection process again and again.
Create a project, add the Form as in Example 1 as follows:

In this project also add an object class (Select the Java Class, not the Java Form), andcreate a constructor in class for the connection process as follows:

In the form that had previously designed to add the following event CONNECTIONTEST button, and run.

Example 3
Process connection can also be placed in a different package with the form.
Create a new project, add a form similar to Example 1 and Example 2 earlier.

At the Source Package, Right-click the package name is the same with your project,select New à Java Package

Dialog will appear to fill in the name of the package. Replace newpackage with data.Click the Finish button.

Will form a new package by name tigakoneksi.data can be seen as follows:

Right-click the new package, add a Java Class object, write the following code:

In draft form, add the following event for the button CONNECTION TEST 2:

If the error sign appears, right click on the lines of program code, select Fix Imports.Will automatically add the name of a new package that we have the following:

Run.

What is "JAVA"?

2011-05-19T13:17:00.001+07:00

Among the many existing software, we often hear the term Java, called Java or J2ME (Java 2 Micro Edition), which is derived from the Java language, where its functions focused on making applications to the mobile environment.
Java is a software technology that in it includes a programming language. In addition, Java also is a platform that has a virtual machine and libraries needed to write and run a program.
Java Initially developed in the computer environment by Sun Microsystems Inc. with the aim to produce a simple computer language without having attached to a specific architecture.
In 1995 Sun released a Java-based browser with the nickname of Hot Java, and subsequently decided to make Netscape's browser equipped with Java language.
Afterwards, join them too many reputable developers IBM and Microsoft.
The following year, Sun Microsystems Inc.. release of the Java Software Development Kit (JDK) first, which is JDK 1.1. Then continue to develop the programming that runs the applet in the browser into a world-class programming that is widely used for the development of a variety of applications.
The Java programming language itself broadly grouped into 3, namely Java 2 Standard Edition (J2SE), Java 2 Enterprise Edition (J2EE) and Java 2 Micro Edition (J2ME).
J2SE is used to develop desktop applications and applets.
J2EE is used to develop applications based on client / server enterprise scale.
And J2ME applied to a variety of small devices with the amount of memory, storage capacity and limited user interface, such as mobile phones and PDAs.
Until now there are two versions of the Java J2ME platform which is commonly used in the MIDP 1.0 mobile phones that still have a simple specification and provide basic functionality for mobile applications, including basic user interface and network security. And MIDP 2.0 which has added a variety of facilities such as gaming, multimedia, support various types of connectivity, as well as OTA.

Creating a blog using CSS menus

2011-05-11T15:48:00.000+07:00

Before there is such thing as CSS code, the navigation menu created by using tables with HTML code. Whether it be horizontal or vertical menu. In fact, to make a website layout still use tables. Well ... if you've no time now to make a navigation menu with table had no other way is by using CSS code. Here's the ropes and hopefully can be understood .........
Creating a blog using CSS menus
Before starting, please note that in order to place the CSS code in a blog that is must be between <head> tag and </ head>. Or to be more easily, keep the above code
]]></ B: skin>
</ Head>
Ok .... immediately wrote to how to create CSS code for menu navigation.
First you must create a first code tag css for the navigation menu settings. See the code below:
# Menu
{
margin-bottom: 10px;
height: 29px;
background: transparent;
padding: 0px 0;
}
Then, create a CSS code to change the default format for ul and li tags
# Menu ul
{
margin: 0;
padding: 7px;
height: 29px;
text-align: center;
}
# Menu ul li
{
list-style: none;
display: inline;
}
The purpose of the CSS code above is to change the format tag ul from vertical to horizontal and set the margin and padding for each menu navigation. Next, make a CSS code to create a variety of links from the navigation menu. code:
# Menu ul li a: link, # menu ul li a: active, # menu ul li a: visited
{
color: white;
margin-bottom: 4px;
padding: 13px 13px 7px 7px;
font-size: 1em;
font-family: 'lucida grande', arial, sans-serif;
font-weight: bold;
text-decoration: yes;
background: url (http://i283.photobucket.com/albums/kk315/
meezanx_2008/menu.gif) repeat-x;
background-position: center;
}
# Menu ul li a: hover
{
color: white;
}
Well ..... the above code is a tutorial that all CSS code mebuat navigation menu. For more details and how to save tersbut code in your blog template follow these steps:
* Log in to Blogger and then select and edit the HTML layout
* For security please download your template first
* Remember .... Do not give a checklist on the box Expand Widget Templates.

background-position: center;
}
# Menu ul li a: hover
{
color: white;
}
* After finishing his copy and paste, locate the following code:
<div id='content-wrapper''>
* If you have found (have to) copy the following code above the html code
<! - START MENU ->
<div id='menu'>
<div style='display:none;'>
<img alt='preload' src='menuon.png'/>
</ Div>
<ul>
<li> <a href='URL ANDA' target='_blank"> Your Text </ a> </ li>
<li> <a href='URL ANDA' target='_blank"> Your Text </ a> </ li>
<li> <a href='URL ANDA' target='_blank"> Your Text </ a> </ li>
<li> <a href='URL ANDA' target='_blank"> Your Text </ a> </ li>
</ Ul>
</ Div>
<! - END MENU ->
Important Note:
1. CHANGE YOUR URL to link your purpose and your Text with the name of each - each link. See How to Make Link.
2. If you understand the CSS code, CSS code you can replace him, according to your needs.
If it is completed, save the template.

CSS (CASCADING STYLE SHEET)

2011-05-06T08:32:00.000+07:00

1. Introduction to CSS
Cascading Style Sheets is a technology used to beautify
website page views (the site). With the overall color and CSS Method
display in a web site can be converted / reformatted quickly. CSS also
been in standartkan by the World Wide Web Consortium (W3C) for use on the web
browser.

Writing CSS
<style Type="text/css">
... CSS ...
</ STYLE>

Example:
<h1 style="color:red;"> Red, hahaha ...</ h1>

2. The terms in the Style Sheet
Style rules
Cascading style sheets is a collection of rules that define
style from the document. As an example we can create the style rules
determine that all <H2> display with the color orange.
Style sheets
Style sheets can be embedded into HTML document. Or called
embedded style sheet. Style sheets can also be made as an external file
and the link to an HTML document. Style roles can be wearing on the
of a certain web page. For example you can determine
certain paragraphs in the show with bold and italic style while
others remain as usual.
Selector
property1 {selector: value, property2: value,. . .}
h1 {color: green; background-color: orange;}

Style sheets consist of two parts:
1. Selector
The first part before the "{}" is called selector
2. Declaration
Consisting of the property and its value.
3. Use the style element
Let's start by setting the font color and background. You
can do this by using the style element to
set the character code tags of your document.
a. Inheritance (Inheritance):

<html>
<head>
<style type="text/css" media=”all”>
b { color : green; }
</style>
</head>
<body>
<b>

Q: Why, if we consider <font size="+1"> a job </ font> it easy
then the real work will become easier?
<br />
A: Because it is a suggestion of ourselves. </ b>
</ body>
</ html>

b. Classes:
This time we define two classes of "ask" and "responsibility" with
CSS rules apply. From here we can see kalu two classes should not
same and can be modified in accordance with the wishes and interests of our needs.

<html>
<head>
<style type="text/css" media=”all”>
.question {color: red;}
.answer {color: blue;}
</style>
</head>
<body>
<p class="question">

Q: Why if we deem it an easy job
then the real work will become easier?
</ p>
<p class="jawab">
A: Because it is a suggestion CLASS="tanya"> <FONT </ FONT>
of ourselves
</ p>
</ body>
</html>

c. Contextual selector (Contextual-Selector)
Contextual selector is similar to conditional statements -
Style-Sheet declaration that there will be an effect if the conditions / circumstances
encountered. For example, suppose you want to make all text bold and italic
performed with arial and blue letters.
Contextual selector, it will be like this:

<head>
<style type="text/css" media=”all”>
b i {color: blue; font-family: Arial;}
/ * this selector all for bold + italic text * /

</style>
</head>

CSS offers a variety of ways to change the color. Is easiest
by using one of the pre-defined colors - aqua, black, blue,
fuchsia, gray, green, lime, maroon, navy, olive, purple, red, silver, teal, white, and yellow.
You can also use hexadecimal color combinations by adding
attribute # (sign Kreiss).
i {color: # 0000FF;)
Or the combination of RGB in the absolute value of percent, like this:
i {color: rgb (0, 0, 255);)
i {color: rgb (0%, 0%, 100%);)
We can change the color combination in accordance with the style that we like.

<html>
<head>
<style type="text/css" media=”all”>
.blue {color: cyan; background-color: #FF8000;}
.green {color: lime; background-color: black;}
</style>
</head>

<body>
<p class="blue">

Actually all the work is easy!

</p>
<p class="green">
Agreed, but not as easy to say it ....
</p>
</body>
</html>

We can also add attributes format for the web we become more alive.
For example, changing the link color, font color add bold, italics, underline,
gives color to the textbox, textarea, scrollbar, and others.

<html>
<head>
<style type="text/css" media=”all”>
body { color: black; background: white; }
i, u { color: red; }
b { color : green; }
</style>
</head>
<body>

Q: Why, if we consider <i> a job </ i> it is easier then the job
real will become easier <b> </ b>? <br />
A: Because it is a suggestion <u> </ u> to <b> ourselves </ b>
</ Body>
</ Html>

<html>
<head>
<style type="text/css" media=”all”>
.question {text-decoration: underline} /* garis bawah */
.answer {text-decoration: overline} /* garis atas text */
.repeat {text-decoration: line-through}/* garis melalui text */
.no-imagination {text-decoration: blink; font-weight: bolder}
/* text berkedip */
</style>
</head>
<body>
<p class="question">
Q. Kenapa why, tidak pernah never, selalu always ?
</p>
<p class="answer">
A. Because Because always always sometime Sometimes?
</p>
<p class="repeat">
Q. Do you know, who the funniest in Indonesia?
</p>
<p class="repeat">
A. I Don’t know, Kasino and Indro.
</p>
<p class="no-imagination">

Haha???
</p>
</body>
</html>

Watermark Concepts
CSS also comes with properties that allow you to define how
how the background image (background) you in the show. First, property
"Background-image" allows you to specify a background image
for each HTML element.
If you require this background as a watermark, which can not
discroll when you to scroll down a page, you must add
property "background-attachment" - The values accepted are "fixed" and "scroll"
You can also set a Yes / No its an image / images that pass through one
page with the property "background-repeat".
This property may be taken one of four parts: a "repeat" (horizontal layout
and vertically), "repeat-x" (horizontal position only), "repeat-y" (location seacara
vertical only), and "no repeat" (no arrangement)
The examples below we take to indicate the keyword "repeat-y", please try:

<html>
<head>
<style type="text/css" media=”all”>
.question {font-size: 20pt; background-image:
url("./letak_folder/bunga.gif"); background-repeat: repeat-y}
</style>

</head>
<body>
<p class="question">
Q. Hmm ... turns out you now have to understand about the concept of a watermark?

A. Yes, There Really is sir!

</p>
</body>
</html>

Model format CSS berasumsi bahwa tiap-tiap elemen dikelilingi oleh tiga area yang
berbeda. Dimulai dari dalam keluar, area ini adalah padding, border, dan margin.
Masing-masing entitas ini dapat diatur melalui spesial properties CSS, mengijinkan para
developer untuk secara singkat mengatur tampilan dan posisi dari setiap elemen HTML.
Nilai margin (garis tepi) dapat kita atur besar dan letaknya melalui properti “margin-top”,
“margin-bottom”, “margin-right”, dan “margin-left”.

<html>
<head> </head>
<body>
<div style="position: absolute; top:10; left:50; font-family: Verdana;
font-size: 35pt; color: green;">

4. ORGANIZING FILE CSS
One of several technological prowess css is - and is the reason many people
Like its use - is to allow us to define a
global style sheet that can apply css rules to the overall
HTML documents on your pages.
The advantage is clear, if we want to change the look of the site, we live editing
one file only and the results will be reflected on the overall HTML document
linked to it.
Example:
Create a folder named css - create a file named global.css. Move the CSS tag
of the file. html to global.css. To give effect rules all Style-Sheet
or to a specific HTML document, add the tag between <HEAD> ... </ HEAD>, becomes:

<head>
<link rek="stylesheet" href=http://PROGRAMMINGHAHA.BLOGSPOT.COM/style/global.css
type="text/css" media=”all” />
</head>

and all rules of Style-sheet in "global.css" will be applied automatically
into HTML documents that want to be informed Style-Sheet. Or can also import
Style-Sheet by using keywords (keyword) "@import",

<style type="text/css" media=”all”>
@import url(http://PROGRAMMINGHAHA.BLOGSPOT.COM /global.css);
</style>

Change Title Case Using String Functions Being Ucwords

2011-05-05T16:10:00.000+07:00

there any php functions that are used to convert a string into upper case, lower case or title case. For this time I just want to discuss ucwords function. Ucwords function is a function that is used to change the characters of a string to title case form

Syntax of function ucwords:
$ output = ucwords ($ change);
variable $ output is a place used for storing strings that have been dibuah by ucwords function.
The variable $ change is a string that want dichange into title case.
Source code (save it as ucwords.php):

   1:  <title>ucwords</title>

   2:  <center>

   3:  <form action="ucwords.php" method="get">

   4:    <table width="222" border="0">

   5:      <tr>

   6:        <td width="68">sentence</td>

   7:        <td width="144"><input type="text" name="sentence" value="&lt;?php echo $_GET[sentence]; ?>" /></td>

   8:      </tr>

   9:      <tr>

  10:        <td colspan="2" align="center"><input type="submit" name="submit" value="process" /></td>

  11:        </tr>

  12:    </table>

  13:  </form>

  14:  <?php

  15:  if ($_GET[submit]=="process") {

  16:  ?>

  17:  sentence<b><?php echo $_GET[sentence]; ?></b> after using the function becomes ucwords berchange

  18:  <?php

  19:  $sentence=ucwords($_GET[sentence]);

  20:  echo "&lt;b>$sentence</b>";

  21:  }

  22:  ?>

  23:  </center>

<?php
if ($_GET[submit]=="process") {
?>sentence<?php echo $_GET[sentence]; ?> after using the function becomes ucwords berchange The above is a preview, the extension must php

DATABASE BASIC CONCEPTS

2011-05-02T22:05:00.000+07:00

do not know about databases? basik data is used to make the program. database is very closely related to sql. BACKGROUND Database processing into the mainstay and its presence is required by the various institutions and companies In developing the required database information system as data storage media The presence of the database can improve company performance and to improve the competitiveness of the company The database can speed up efforts to customer service to produce information quickly and accurately help decision makers to quickly decide an issue based on existing information

EXAMPLE APPLICATIONS on banking transactions flight reservations and scheduling applications registration process and recording of data on college students application to process the sale, purchase and recording of data on goods trading company recording of employee data and payroll activities including the operation of an enterprise etc..

COMPANY INFORMATION FOR RETAIL ... search sales look for the amount of stock available what is the best-selling goods sold on this month net profit INFORMATION FOR THE LIBRARY ... Data search of books by title, author or other criteria can be easily done with the data base Search borrowers who are late returning data is also easy to do so could be made an application making the invoice based on the information available
Taking advantage of network technologies, the ability of the database can be optimized such inter-branch transactions on an online banking
DEFINITIONS
The database is a collection of data that relate to each other
The data itself is a fact about objects, people and others. Data expressed as values (numbers, sequences of characters, or symbols).
The set of interrelated sets of data are organized in such a way that it can later be used to quickly and easily
A collection of interrelated data stored together in such a way without repetition (redundancy) is not necessary, to meet the needs of
Collection of files / tables / archives related stored in electronic storage media
PURPOSE
arrange the data so obtained the ease, accuracy and speed in decision again
TERMS
The lack of redundancy and data inconsistency
Redundancy occurs when an information is stored in several places.
For example:
NIM containing student data, name, address and other attributes
KHS student data whose contents have NIM, name, mata_kuliah and Value.

BASIC XML

2011-04-30T16:31:00.000+07:00

What is XML?

XML stands for EXtensible Markup Language
XML is a markup language much like HTML
XML was designed to carry data, not to display data
XML tags are not predefined. You must define your own tags
XML is designed to be self-descriptive
XML is a W3C Recommendation

The Difference Between XML and HTML

XML is not a replacement for HTML.
XML and HTML were designed with different goals:

XML was designed to transport and store data, with focus on what data is.
HTML was designed to display data, with focus on how data looks.

HTML is about displaying information, while XML is about carrying information.

XML Does not DO Anything

Maybe it is a little hard to understand, but XML does not DO anything. XML was created to structure, store, and transport information.

The following example is a note to Tove from Jani, stored as XML:

<note>

<to>Tove</to>

<from>Jani</from>

<heading>Reminder</heading>

<body>Don't forget me this weekend!</body>

</note>

The note above is quite self descriptive. It has sender and receiver information, it also has a heading and a message body.

But still, this XML document does not DO anything. It is just pure information wrapped in tags. Someone must write a piece of software to send, receive or display it.

XML is Just Plain Text

XML is nothing special. It is just plain text. Software that can handle plain text can also handle XML.

However, XML-aware applications can handle the XML tags specially. The functional meaning of the tags depends on the nature of the application.

With XML You Invent Your Own Tags

The tags in the example above (like <to> and <from>) are not defined in any XML standard. These tags are "invented" by the author of the XML document.

That is because the XML language has no predefined tags.

The tags used in HTML (and the structure of HTML) are predefined. HTML documents can only use tags defined in the HTML standard (like <p>, <h1>, etc.).

XML allows the author to define his own tags and his own document structure.

XML is Not a Replacement for HTML

XML is a complement (pelengkap) to HTML.

It is important to understand that XML is not a replacement for HTML. In most web applications, XML is used to transport data, while HTML is used to format and display the data.

My best description of XML is this:

XML is a software and hardware independent tool for carrying information.

XML is a W3C Recommendation

The Extensible Markup Language (XML) became a W3C Recommendation 10. February 1998.

XML is Everywhere

We have been participating in XML development since its creation. It has been amazing to see how quickly the XML standard has developed and how quickly a large number of software vendors have adopted the standard.

XML is now as important for the Web as HTML was to the foundation of the Web.

XML is everywhere. It is the most common tool for data transmissions between all sorts of applications, and becomes more and more popular in the area of storing and describing information.

How Can XML be Used?

XML is used in many aspects of web development, often to simplify data storage and sharing.

XML Separates Data from HTML

If you need to display dynamic data in your HTML document, it will take a lot of work to edit the HTML each time the data changes.

With XML, data can be stored in separate XML files. This way you can concentrate on using HTML for layout and display, and be sure that changes in the underlying data will not require any changes to the HTML.

With a few lines of JavaScript, you can read an external XML file and update the data content of your HTML.

You will learn more about this in a later chapter of this tutorial.

XML Simplifies Data Sharing

In the real world, computer systems and databases contain data in incompatible formats.

XML data is stored in plain text format. This provides a software- and hardware-independent way of storing data.

This makes it much easier to create data that different applications can share.

XML Simplifies Data Transport

With XML, data can easily be exchanged between incompatible systems.

One of the most time-consuming challenges for developers is to exchange data between incompatible systems over the Internet.

Exchanging data as XML greatly reduces this complexity, since the data can be read by different incompatible applications.

XML Simplifies Platform Changes

Upgrading to new systems (hardware or software platforms), is always very time consuming. Large amounts of data must be converted and incompatible data is often lost.

XML data is stored in text format. This makes it easier to expand or upgrade to new operating systems, new applications, or new browsers, without losing data.

XML Makes Your Data More Available

Since XML is independent of hardware, software and application, XML can make your data more available and useful.

Different applications can access your data, not only in HTML pages, but also from XML data sources.

With XML, your data can be available to all kinds of "reading machines" (Handheld computers, voice machines, news feeds, etc), and make it more available for blind people, or people with other disabilities.

XML is Used to Create New Internet Languages

A lot of new Internet languages are created with XML.

Here are some examples:

XHTML the latest version of HTML

WSDL for describing available web services

WAP and WML as markup languages for handheld devices

RSS languages for news feeds

RDF and OWL for describing resources and ontology

SMIL for describing multimedia for the web

If Developers Have Sense

If they DO have sense, future applications will exchange their data in XML.

The future might give us word processors, spreadsheet applications and databases that can read each other's data in a pure text format, without any conversion utilities in between.

We can only pray that all the software vendors will agree.

XML Tree

XML documents form a tree structure that starts at "the root" and branches to "the leaves".

An Example XML Document

XML documents use a self-describing and simple syntax:

<?xml version="1.0" encoding="ISO-8859-1"?>

<note>

<to>Tove</to>

<from>Jani</from>

<heading>Reminder</heading>

<body>Don't forget me this weekend!</body>

</note>

The first line is the XML declaration. It defines the XML version (1.0) and the encoding used (ISO-8859-1 = Latin-1/West European character set).

The next line describes the root element of the document (like saying: "this document is a note"):

<note>

The next 4 lines describe 4 child elements of the root (to, from, heading, and body):

<to>Tove</to>

<from>Jani</from>

<heading>Reminder</heading>

<body>Don't forget me this weekend!</body>

And finally the last line defines the end of the root element:

</note>

You can assume, from this example, that the XML document contains a note to Tove from Jani.

Don't you agree that XML is pretty self-descriptive?

XML Documents Form a Tree Structure

XML documents must contain a root element. This element is "the parent" of all other elements.

The elements in an XML document form a document tree. The tree starts at the root and branches to the lowest level of the tree.

All elements can have sub elements (child elements):

<root>

  <child>

    <subchild>.....</subchild>

  </child>

</root>

The terms parent, child, and sibling (saudara kandung) are used to describe the relationships between elements. Parent elements have children. Children on the same level are called siblings (brothers or sisters).

All elements can have text content and attributes (just like in HTML).

Example:

The image above represents one book in the XML below:

<bookstore>

<book category="COOKING">

  <title lang="en">Everyday Italian</title>

  <author>Giada De Laurentiis</author>

  <year>2005</year>

  <price>30.00</price>

</book>

<book category="CHILDREN">

  <title lang="en">Harry Potter</title>

  <author>J K. Rowling</author>

  <year>2005</year>

  <price>29.99</price>

</book>

<book category="WEB">

  <title lang="en">Learning XML</title>

  <author>Erik T. Ray</author>

  <year>2003</year>

  <price>39.95</price>

</book>

</bookstore>

The root element in the example is <bookstore>. All <book> elements in the document are contained within <bookstore>.

The <book> element has 4 children: <title>,< author>, <year>, <price>.

XML Syntax Rules

The syntax rules of XML are very simple and logical. The rules are easy to learn, and easy to use.

All XML Elements Must Have a Closing Tag

In HTML, you will often see elements that don't have a closing tag:

<p>This is a paragraph

<p>This is another paragraph

In XML, it is illegal to omit the closing tag. All elements must have a closing tag:

<p>This is a paragraph</p>

<p>This is another paragraph</p>

Note: You might have noticed from the previous example that the XML declaration did not have a closing tag. This is not an error. The declaration is not a part of the XML document itself, and it has no closing tag.

XML Tags are Case Sensitive

XML elements are defined using XML tags.

XML tags are case sensitive. With XML, the tag <Letter> is different from the tag <letter>.

Opening and closing tags must be written with the same case:

<Message>This is incorrect</message>

<message>This is correct</message>

Note: "Opening and closing tags" are often referred to as "Start and end tags". Use whatever you prefer. It is exactly the same thing.

XML Elements Must be Properly Nested

In HTML, you will often see improperly nested elements:

<b><i>This text is bold and italic</b></i>

In XML, all elements must be properly nested within each other:

<b><i>This text is bold and italic</i></b>

In the example above, "Properly nested" simply means that since the <i> element is opened inside the <b> element, it must be closed inside the <b> element.

XML Documents Must Have a Root Element

XML documents must contain one element that is the parent of all other elements. This element is called the root element.

<root>

  <child>

    <subchild>.....</subchild>

  </child>

</root>

XML Attribute Values Must be Quoted

XML elements can have attributes in name/value pairs just like in HTML.

In XML the attribute value must always be quoted. Study the two XML documents below. The first one is incorrect, the second is correct:

<note date=12/11/2007>

<to>Tove</to>

<from>Jani</from>

</note>

<note date="12/11/2007">

<to>Tove</to>

<from>Jani</from>

</note>

The error in the first document is that the date attribute in the note element is not quoted.

Entity References

Some characters have a special meaning in XML.

If you place a character like "<" inside an XML element, it will generate an error because the parser interprets it as the start of a new element.

This will generate an XML error:

<message>if salary < 1000 then</message>

To avoid this error, replace the "<" character with an entity reference:

<message>if salary &lt; 1000 then</message>

There are 5 predefined entity references in XML:

<	<	less than
>	>	greater than
&	&	ampersand
'	'	apostrophe
"	"	quotation mark

Note: Only the characters "<" and "&" are strictly illegal in XML. The greater than character is legal, but it is a good habit to replace it.

Comments in XML

The syntax for writing comments in XML is similar to that of HTML.

With XML, White Space is Preserved

HTML reduces multiple white space characters to a single white space:

HTML:	Hello my name is Tove
Output:	Hello my name is Tove.

With XML, the white space in your document is not truncated.

XML Stores New Line as LF

In Windows applications, a new line is normally stored as a pair of characters: carriage return (CR) and line feed (LF). The character pair bears some resemblance (kemiripan) to the typewriter actions of setting a new line. In Unix applications, a new line is normally stored as a LF character. Macintosh applications use only a CR character to store a new line.

XML Elements

An XML document contains XML Elements.

What is an XML Element?

An XML element is everything from (including) the element's start tag to (including) the element's end tag.

An element can contain other elements, simple text or a mixture of both. Elements can also have attributes.

<bookstore>

<book category="CHILDREN">

  <title>Harry Potter</title>

  <author>J K. Rowling</author>

  <year>2005</year>

  <price>29.99</price>

</book>

<book category="WEB">

  <title>Learning XML</title>

  <author>Erik T. Ray</author>

  <year>2003</year>

  <price>39.95</price>

</book>

</bookstore>

In the example above, <bookstore> and <book> have element contents, because they contain other elements. <author> has text content because it contains text.

In the example above only <book> has an attribute (category="CHILDREN").

XML Naming Rules

XML elements must follow these naming rules:

Names can contain letters, numbers, and other characters

Names must not start with a number or punctuation character

Names must not start with the letters xml (or XML, or Xml, etc)

Names cannot contain spaces

Any name can be used, no words are reserved.

Best Naming Practices

Make names descriptive. Names with an underscore separator are nice: <first_name>, <last_name>.

Names should be short and simple, like this: <book_title> not like this: <the_title_of_the_book>.

Avoid "-" characters. If you name something "first-name," some software may think you want to subtract name from first.

Avoid "." characters. If you name something "first.name," some software may think that "name" is a property of the object "first."

Avoid ":" characters. Colons are reserved to be used for something called namespaces (more later).

XML documents often have a corresponding database. A good practice is to use the naming rules of your database for the elements in the XML documents.

Non-English letters like éòá are perfectly legal in XML, but watch out for problems if your software vendor doesn't support them.

XML Elements are Extensible

XML elements can be extended to carry more information.

Look at the following XML example:

<note>

<to>Tove</to>

<from>Jani</from>

<body>Don't forget me this weekend!</body>

</note>

Let's imagine that we created an application that extracted the <to>, <from>, and <body> elements from the XML document to produce this output:

MESSAGE

To: Tove

From: Jani

Don't forget me this weekend!

Imagine that the author of the XML document added some extra information to it:

<note>

<date>2008-01-10</date>

<to>Tove</to>

<from>Jani</from>

<heading>Reminder</heading>

<body>Don't forget me this weekend!</body>

</note>

Should the application break or crash?

No. The application should still be able to find the <to>, <from>, and <body> elements in the XML document and produce the same output.

One of the beauties of XML, is that it can often be extended without breaking applications.

XML Attributes

XML elements can have attributes in the start tag, just like HTML.

Attributes provide additional information about elements.

XML Attributes

From HTML you will remember this: <img src="computer.gif">. The "src" attribute provides additional information about the <img> element.

In HTML (and in XML) attributes provide additional information about elements:

<img src="computer.gif">

<a href="demo.asp">

Attributes often provide information that is not a part of the data. In the example below, the file type is irrelevant to the data, but important to the software that wants to manipulate the element:

<file type="gif">computer.gif</file>

XML Attributes Must be Quoted

Attribute values must always be enclosed in quotes, but either single or double quotes can be used. For a person's sex, the person tag can be written like this:

<person sex="female">

or like this:

<person sex='female'>

If the attribute value itself contains double quotes you can use single quotes, like in this example:

<gangster name='George "Shotgun" Ziegler'>

or you can use character entities:

<gangster name="George &quot;Shotgun&quot; Ziegler">

XML Elements vs. Attributes

Take a look at these examples:

<person sex="female">

  <firstname>Anna</firstname>

  <lastname>Smith</lastname>

</person>

<person>

  <sex>female</sex>

  <firstname>Anna</firstname>

  <lastname>Smith</lastname>

</person>

In the first example sex is an attribute. In the last, sex is an element. Both examples provide the same information.

There are no rules about when to use attributes and when to use elements. Attributes are handy in HTML. In XML my advice is to avoid them. Use elements instead.

My Favorite Way

The following three XML documents contain exactly the same information:

A date attribute is used in the first example:

<note date="10/01/2008">

<to>Tove</to>

<from>Jani</from>

<heading>Reminder</heading>

<body>Don't forget me this weekend!</body>

</note>

A date element is used in the second example:

<note>

<date>10/01/2008</date>

<to>Tove</to>

<from>Jani</from>

<heading>Reminder</heading>

<body>Don't forget me this weekend!</body>

</note>

An expanded date element is used in the third: (THIS IS MY FAVORITE):

<note>

<date>

  <day>10</day>

  <month>01</month>

  <year>2008</year>

</date>

<to>Tove</to>

<from>Jani</from>

<heading>Reminder</heading>

<body>Don't forget me this weekend!</body>

</note>

Avoid XML Attributes?

Some of the problems with using attributes are:

attributes cannot contain multiple values (elements can)

attributes cannot contain tree structures (elements can)

attributes are not easily expandable (for future changes)

Attributes are difficult to read and maintain. Use elements for data. Use attributes for information that is not relevant to the data.

Don't end up like this:

<note day="10" month="01" year="2008"

to="Tove" from="Jani" heading="Reminder"

body="Don't forget me this weekend!">

</note>

XML Attributes for Metadata

Sometimes ID references are assigned to elements. These IDs can be used to identify XML elements in much the same way as the ID attribute in HTML. This example demonstrates this:

<messages>

  <note id="501">

    <to>Tove</to>

    <from>Jani</from>

    <heading>Reminder</heading>

    <body>Don't forget me this weekend!</body>

  </note>

  <note id="502">

    <to>Jani</to>

    <from>Tove</from>

    <heading>Re: Reminder</heading>

    <body>I will not</body>

  </note>

</messages>

The ID above is just an identifier, to identify the different notes. It is not a part of the note itself.

What I'm trying to say here is that metadata (data about data) should be stored as attributes, and that data itself should be stored as elements.

XML Validation

XML with correct syntax is "Well Formed" XML.

XML validated against a DTD is "Valid" XML.

Well Formed XML Documents

A "Well Formed" XML document has correct XML syntax.

The syntax rules were described in the previous chapters:

XML documents must have a root element

XML elements must have a closing tag

XML tags are case sensitive

XML elements must be properly nested

XML attribute values must be quoted

<?xml version="1.0" encoding="ISO-8859-1"?>

<note>

<to>Tove</to>

<from>Jani</from>

<heading>Reminder</heading>

<body>Don't forget me this weekend!</body>

</note>

Valid XML Documents

A "Valid" XML document is a "Well Formed" XML document, which also conforms to the rules of a Document Type Definition (DTD):

<?xml version="1.0" encoding="ISO-8859-1"?>

<!DOCTYPE note SYSTEM "Note.dtd">

<note>

<to>Tove</to>

<from>Jani</from>

<body>Don't forget me this weekend!</body>

</note>

The DOCTYPE declaration in the example above, is a reference to an external DTD file. The content of the file is shown in the paragraph below.

XML DTD

The purpose of a DTD is to define the structure of an XML document. It defines the structure with a list of legal elements:

<!DOCTYPE note [

  <!ELEMENT note (to,from,heading,body)>

  <!ELEMENT to      (#PCDATA)>

  <!ELEMENT from    (#PCDATA)>

  <!ELEMENT heading (#PCDATA)>

  <!ELEMENT body    (#PCDATA)>

]>

If you want to study DTD, you will find our DTD tutorial on our homepage.

XML Schema

W3C supports an XML based alternative to DTD called XML Schema:

<xs:element name="note">

<xs:complexType>

  <xs:sequence>

    <xs:element name="to"      type="xs:string"/>

    <xs:element name="from"    type="xs:string"/>

    <xs:element name="heading" type="xs:string"/>

    <xs:element name="body"    type="xs:string"/>

  </xs:sequence>

</xs:complexType>

</xs:element>

If you want to study XML Schema, you will find our Schema tutorial on our homepage.

A General XML Validator

To help you check the syntax of your XML files, we have created an XML validator to syntax-check your XML.

Please see the next chapter.

XML Validator

Use our XML validator to syntax-check your XML.

XML Errors Will Stop You

Errors in XML documents will stop your XML applications.

The W3C XML specification states that a program should stop processing an XML document if it finds an error. The reason is that XML software should be small, fast, and compatible.

HTML browsers will display documents with errors (like missing end tags). HTML browsers are big and incompatible because they have a lot of unnecessary code to deal with (and display) HTML errors.

With XML, errors are not allowed.

Syntax-Check Your XML

To help you syntax-check your XML, we have created an XML validator.

Paste your XML into the text area below, and syntax-check it by clicking the "Validate" button.

<?xml version="1.0" ?> <note> <to>Tove</to> <from>Jani</Ffrom> <heading>Reminder</heading> <body>Don't forget me this weekend!</body> </note>

Note: This only checks if your XML is "Well formed". If you want to validate your XML against a DTD, see the last paragraph on this page.

Syntax-Check an XML File

You can syntax-check an XML file by typing the URL of the file into the input field below, and then click the "Validate" button:

Filename:

Note: If you get an "Access denied" error, it's because your browser security does not allow file access across domains.

The file "note_error.xml" demonstrates your browsers error handling. If you want see an error free message, substitute the "note_error.xml" with "cd_catalog.xml".

Validate Your XML Against a DTD

If you know DTD, you can validate your XML in the text area below.

Just add the DOCTYPE declaration to your XML and click the "Validate" button:

<?xml version="1.0" ?> <!DOCTYPE note [ <!ELEMENT note (to,from,heading,body)> <!ELEMENT to (#PCDATA)> <!ELEMENT from (#PCDATA)> <!ELEMENT heading (#PCDATA)> <!ELEMENT body (#PCDATA)> ]> <note> <to>Tove</to> <from>Jani</from> <heading>Reminder</heading> <message>Don't forget me this weekend!</message> </note>

Note: Only Internet Explorer will actually check your XML against the DTD. Firefox, Mozilla, Netscape, and Opera will not.

Viewing XML Files

Raw XML files can be viewed in all major browsers.

Don't expect XML files to be displayed as HTML pages.

Viewing XML Files

<?xml version="1.0" encoding="ISO-8859-1"?>

- <note>

<heading>Reminder<heading>

<body>Don't forget me this weekend!<body>

<note>

Look at this XML file: note.xml

The XML document will be displayed with color-coded root and child elements. A plus (+) or minus sign (-) to the left of the elements can be clicked to expand or collapse the element structure. To view the raw XML source (without the + and - signs), select "View Page Source" or "View Source" from the browser menu.

Note: In Netscape, Opera, and Safari, only the element text will be displayed. To view the raw XML, you must right click the page and select "View Source"

Viewing an Invalid XML File

If an erroneous XML file is opened, the browser will report the error.

Look at this XML file: note_error.xml

Other XML Examples

Viewing some XML documents will help you get the XML feeling.

An XML CD catalog

This is a CD collection, stored as XML data.

An XML plant catalog

This is a plant catalog from a plant shop, stored as XML data.

A Simple Food Menu

This is a breakfast food menu from a restaurant, stored as XML data.

Why Does XML Display Like This?

XML documents do not carry information about how to display the data.

Since XML tags are "invented" by the author of the XML document, browsers do not know if a tag like <table> describes an HTML table or a dining table.

Without any information about how to display the data, most browsers will just display the XML document as it is.

In the next chapters, we will take a look at different solutions to the display problem, using CSS, XSLT and JavaScript.

Displaying XML with CSS

With CSS (Cascading Style Sheets) you can add display information to an XML document.

Displaying your XML Files with CSS?

It is possible to use CSS to format an XML document.

Below is an example of how to use a CSS style sheet to format an XML document:

Take a look at this XML file: The CD catalog

Then look at this style sheet: The CSS file

Finally, view: The CD catalog formatted with the CSS file

Below is a fraction of the XML file. The second line links the XML file to the CSS file:

<?xml version="1.0" encoding="ISO-8859-1"?>

<?xml-stylesheet type="text/css" href="cd_catalog.css"?>

<CATALOG>

  <CD>

    <COMPANY>CBS Records</COMPANY>

    <PRICE>9.90</PRICE>

    <YEAR>1988</YEAR>

  </CD>

</CATALOG>

Formatting XML with CSS is not the most common method.

W3C recommend using XSLT instead. See the next chapter.

Displaying XML with XSLT

With XSLT you can transform an XML document into HTML.

Displaying XML with XSLT

XSLT is the recommended style sheet language of XML.

XSLT (eXtensible Stylesheet Language Transformations) is far more sophisticated than CSS.

One way to use XSLT is to transform XML into HTML before it is displayed by the browser as demonstrated in these examples:

View the XML file, the XSLT style sheet, and View the result.

Below is a fraction of the XML file. The second line links the XML file to the XSLT file:

<?xml version="1.0" encoding="ISO-8859-1"?>

<?xml-stylesheet type="text/xsl" href="simple.xsl"?>

<breakfast_menu>

  <food>

    <name>Belgian Waffles</name>

    <price>$5.95</price>

    <description>

       two of our famous Belgian Waffles

    </description>

    <calories>650</calories>

  </food>

</breakfast_menu>

If you want to learn more about XSLT, find our XSLT tutorial on our homepage.

Transforming XML with XSLT on the Server

In the example above, the XSLT transformation is done by the browser, when the browser reads the XML file.

Different browsers may produce different result when transforming XML with XSLT. To reduce this problem the XSLT transformation can be done on the server.

View the result.

Note that the result of the output is exactly the same, either the transformation is done by the web server or by the web browser.

XML JAVASCRIPT

XML Parser

Most browsers have a build-in XML parser to read and manipulate XML.

The parser converts XML into a JavaScript accessible object.

Examples

W3Schools examples are browser and platform independent. These examples work in all modern browsers.

Load and parse an XML file

Load and parse an XML string

Parsing XML

All modern browsers have a build-in XML parser that can be used to read and manipulate XML.

The parser reads XML into memory and converts it into an XML DOM object that can be accesses with JavaScript.

You will learn more about the XML DOM in the next chapter of this tutorial.

There are some differences between Microsoft's XML parser and the parsers used in other browsers. The Microsoft parser supports loading of both XML files and XML strings (text), while other browsers use separate parsers. However, all parsers contain functions to traverse XML trees, access, insert, and delete nodes (elements) and their attributes.

In this tutorial we will show you how to create scripts that will work in both Internet Explorer and other browsers.

Note: When we talk about parsing XML, we often use the term "Nodes" about XML elements.

Loading XML with Microsoft's XML Parser

Microsoft's XML parser is built into Internet Explorer 5 and higher.

The following JavaScript fragment loads an XML document ("note.xml") into the parser:

var xmlDoc=new ActiveXObject("Microsoft.XMLDOM");

xmlDoc.async="false";

xmlDoc.load("note.xml");

Example explained:

The first line of the script above creates an empty Microsoft XML document object.

The second line turns off asynchronized loading, to make sure that the parser will not continue execution of the script before the document is fully loaded.

The third line tells the parser to load an XML document called "note.xml".

The following JavaScript fragment loads a string called txt into the parser:

var xmlDoc=new ActiveXObject("Microsoft.XMLDOM");

xmlDoc.async="false";

xmlDoc.loadXML(txt);

Note: The loadXML() method is used for loading strings (text), load() is used for loading files.

XML Parser in Firefox and Other Browsers

The following JavaScript fragment loads an XML document ("note.xml") into the parser:

var xmlDoc=document.implementation.createDocument("","",null);

xmlDoc.async="false";

xmlDoc.load("note.xml");

Example explained:

The first line of the script above creates an empty XML document object.

The second line turns off asynchronized loading, to make sure that the parser will not continue execution of the script before the document is fully loaded.

The third line tells the parser to load an XML document called "note.xml".

The following JavaScript fragment loads a string called txt into the parser:

var parser=new DOMParser();

var doc=parser.parseFromString(txt,"text/xml");

Example explained:

The first line of the script above creates an empty XML document object.

The second line tells the parser to load a string called txt.

Note: Internet Explorer uses the loadXML() method to parse an XML string, while other browsers uses the DOMParser object.

Access Across Domains

For security reasons, modern browsers does not allow access across domains.

This means, that both the web page and the XML file it tries to load, must be located on the same server.

The examples on W3Schools all open XML files located on the W3Schools domain.

If you want to use the example above on one of your web pages, the XML files you load must be located on your own server. Otherwise the xmlDoc.load() method, will generate the error "Access is denied".

The XML DOM

In the next chapter of this tutorial, you will learn how to access and retrieve data from the XML document object (the XML DOM).

<html>

<head>

function parseXML()

{

try //Internet Explorer

{

xmlDoc=new ActiveXObject("Microsoft.XMLDOM");

}

catch(e)

{

try //Firefox, Mozilla, Opera, etc.

{

xmlDoc=document.implementation.createDocument("","",null);

}

catch(e)

{

alert(e.message);

return;

}

xmlDoc.async=false;

xmlDoc.load("note.xml");

document.getElementById("to").innerHTML=xmlDoc.getElementsByTagName("to")[0].childNodes[0].nodeValue;

document.getElementById("from").innerHTML=xmlDoc.getElementsByTagName("from")[0].childNodes[0].nodeValue;

document.getElementById("message").innerHTML=xmlDoc.getElementsByTagName("body")[0].childNodes[0].nodeValue;

laying JavaScript

2011-04-29T07:26:00.000+07:00

Where to Put the JavaScript

JavaScripts in a page will be executed immediately while the page loads into the browser. This is not always what we want. Sometimes we want to execute a script when a page loads, other times when a user triggers an event.

Scripts in the head section: Scripts to be executed when they are called, or when an event is triggered, go in the head section. When you place a script in the head section, you will ensure that the script is loaded before anyone uses it.

Scripts in the body section: Scripts to be executed when the page loads go in the body section. When you place a script in the body section it generates the content of the page.

Scripts in both the body and the head section: You can place an unlimited number of scripts in your document, so you can have scripts in both the body and the head section.

Structures Condition and Repetition section

2011-04-29T07:01:00.000+07:00

hey hey, You can implement this in php, and other programming languages,. The following is basic to know the loop

1. Structure Condition
Branching control structures (decision making) that control the structure function
to conduct elections for the command to be executed in accordance with certain conditions.
There are four branching orders in PHP, that is if, if .. else, if .. elseif, and switch.

Structure Condition If

stucture condition If
if (condition) {
statement-if-condition-true;
}

Description:
condition is a statement or a variable that should be checked TRUE or FALSE.

Structure Condition If ... Else
If ... else command is used to select a statement based on a
condition. This command will execute a particular statement if the condition is true and will
run another statement if the condition is false. Syntax is
as follows:

if (condition) {
statement-if-condition-true;
} else {
statement-if-conditio -false;
}

Description:
condition of a statement or a variable that should be checked his TRUE or FALSE. If
the condition is TRUE, the statement in the if block will be executed, otherwise if
the condition is FALSE, the statement in the else block will be executed.

Structure Condition Switch ... Case
Command switches used as an alternative of the if ... elseif command. With
This command branching program will be more easily prepared and studied. Syntax writing
command switches are as follows:

switch (condition)
{
case constants_1:
statement_1;
break;
case constants_2:
statement_2;
break;

default:
statement_3;
}

Information
Command switch will select the given conditions and compare the results with
constants that are on the case. Benchmarking will start from konstanta_1
until the last constant. If the result of a condition equal to the value of certain constants, then
statement on these constants will run until the break statement is found. If
results from the same condition with no constants are given, then
the default statement will be executed.

Register On Vs Global Register Global Off

2011-04-21T13:20:00.000+07:00

At the beginning of its development, by default the global registers in the set of On the
tujuang to give the user ease in learning PHP, so that users can take / call variable simply by mentioning the name variables, no matter whether the variable comes from GET, POST, COOKIE, or SESSION. An example script follows:
Scripts "globalon.php"

   1:  <? Php

   2:  echo "<form method=GET action=globalon.php>

   3:  Enter your name: <input type=text name='nama'>

   4:  <input type=submit name=oke value=kirim> </ form> ";

   5:  if ($ ok == 'send') {

   6:  echo "Your name is: <b> $ name </ b>";

   7:  }

   8:  ?>

However, since version 4.3.X and above, then the default value of global register = Off, so if globalon.php script is run, it will not produce anything. So for the script to run on register globals = Off, it is necessary variables to be adjusted as follows:

   1:  <? Php

   2:  echo "<form method=GET action=globalon.php>

   3:  Enter your name: <input type=text name='nama'>

   4:  <input type=submit name=oke value=kirim> </ form> ";

   5:  if ($ _GET [OK] == 'send') {

   6:  echo "Your name is: <b> $ _GET [name] </ b>";

   7:  }

   8:  ?>

 Note the source of the variable, when using the method / POST parameters,

then calling the variables: $ _POST ['nama_varibel'].

 If the source of the variables taken from the variables that brought the Address bar,

for example: http://localhost/modul/globalon.php?nama=Amikom, then writing

variables: $ _GET ['nama_variabel'].

 The syntax of variables such as $ _ENV, $ _GET, $ _POST, $ _COOKIE, $ _SESSION,

$ _FILES And $ _SERVER is also often called superglobal or autoglobal,

means that these variables can walk anywhere, no matter whether the register

global On or Off.

Flow Learning Java

2011-04-21T00:04:00.000+07:00

Java is an interesting technology but spacious. He can be used for develop solutions for mobile devices that run on enterprise servers. The extent of Java often confuses beginner in learning Java. Not infrequently caught up in the direction that is not maximum, for example control of open software source, such as Struts, Turbine, or Hybernate rather than understand Java itself.
Or stuck to treat the JSP as a scripting language, like culture in PHP. Where do you begin to walk, where you must step on the way your odyssey as a Java developer, preferably tailored to your objectives. Do you want to develop applications for mobile phones, or to run on the enterprise server? This requires a different Java technology for be explored.
Java Platform
Java as a platform for software development, broadly divided into 3
referrals:
J2SE
J2EE
J2ME
J2SE

Java 2 Standard Edition includes the core of the Java programming language, contains librarylibrary
core needs such as IO, networking and JDBC.
J2EE
Java 2 Enterprise Edition is a Java development for enterprise solutions, ranging from
Web-based application with Servlet and JSP, distributed applications with EJB,
enterprise application integration such as Web Service.
J2ME
Java 2 Micro Edition is a Java development for mobile devices, like mobile phone
, Pocket PCs and PDAs. The development direction of mobile devices requires Java to
adapt to the machine that is limited in memory and processor.
Flow Learning Java
Chronology learn Java:
# Determine an objective, such as' I want to be able to make an application for
mobile ', or' I wish I could make a portal with Java ', or' I wish I could
create desktop applications with Java GUI '.
# From these objectives, you can set the agenda to learn Java so that more
directed and focused.
Java Programming Language
As a fundamental knowledge of Java you need to understand:
# the concept of byte-code and Java Virtual Machine
# syntax in the Java programming language as data types, flow control, handling
exception
#OOP in Java
Basic Java
To master the basic Java, among the libraries that need to be well understood are:
# IO, mainly deals with how to access the file with Java, and the concept
byte streams and character streams is needed to understand how
Servlet or JSP work.
3JDBC, deals with how to access the database with Java
Basic Java? Enrichment
The need to master additional material is dependent on your objective in
learn Java:
# Networking, needed for example to develop a client server application, not
Web-based, where you need to design their own communication protocol
# AWT and Swing, are needed if you want to develop desktop applications
with the Java GUI.
# Applet, is required if you need a GUI application that runs on top
browser. These materials may not need to go into if you want to develop Web applications.
Web Applications To be able to develop Web applications, you need to learn:
# Servlet, is a basic technology in the development of Web applications with Java.
#JSP, a servlet development, best used for the presentation layer.
Web Applications - Enrichment
This technology will be useful to improve the quality of Web-based software
You develop:
# Model View Controller
Enterprise Applications --- Basic
You will be much easier, although not mandatory, to understand the Java technology enterprise
by understanding:
# RMI or Remote Method Invocation, is the basis for distributed applications in
Java
# JNDI or Java Naming and Directory Interface
# Or the Java Transaction API JTA
Enterprise Applications --- Main
The main technologies in enterprise applications with Java are:
# EJB or Enterprise Java Bean is a key technology of the Java enterprise.
Advanced Enterprise Applications ---
These are technologies that are still in progress:
# XML or eXtended Markup Language, used them in Web technology
Service
# Web Service, is an architecture in which two applications communicate with each other
using a communication protocol called SOAP. Two applications that communicate
with Web services can be developed with two programming languages
different, and running on two different platforms.
# P2P or Peer-To-Peer, in Java was developed as Project Juxtapose (JXTA)
Mobile Applications
To be able to develop mobile applications, technologies that need to be controlled:
# MIDP or the Mobile Internet Device Profile
Mastering Open Source
Mastery of open source can provide its own power for Java developers. In
among them:
      # Library. As a library that facilitates software development, such as Hybernate, Velocity, Struts
     # Deployment. Not infrequently open source is also required for deployment environment, such as Tomcat, JBoss
     # Process. Or supporting the software development process such as Scarab, Ant

Data Type & Constant

2011-04-20T10:28:00.001+07:00

Data Type

In PHP, the variable data type is not defined by the programmer, but
automatically determined by the PHP interpreter. However, PHP supports 8
(Eight) pieces of primitive data types, namely:
1. boolean
2. integer
3. float
4. string
5. array
6. object
7. resource
8. NULL

PROBLEMS
1. Creating a static variable value to display and save data majors
lat03.php name.
2. Creating a dynamic variable value to display and save data majors
lat04.php name.

   1:  <? Php

   2:  $ NIM = "09.12.9999";

   3:  $ Name = 'STMIK AMIKOM YOGYAKARTA';

   4:  $ Age = 16;

   5:  $ Value = 82.25;

   6:  $ Status = TRUE;

   7:  echo "NIM". $ NIM. "<br>";

   8:  echo "Name: $ name <br>";

   9:  print "Age:". $ age;

  10:  print "<br>";

  11:  printf ("Value:% .3 f <br>", $ value);

  12:  if ($ status)

  13:  echo "Status: Active";

  14:  else

  15:  echo "Status: Not Active";

  16:  ?>

Constant

Constant is a variable whose value is fixed. Constant only rated at

beginning of the program and its value is never changed during the program runs.PHP has

defines some constants, eg: PHP_VERSION, ie constant

provide information about the PHP version being used. In addition to constants that have been

provided by the PHP we also can create their own constants. Writing rules

constants are as follows:

define ("nama_konstanta", "nilai_konstanta")

Examples of the use of constants:

Save with the name "Lat05.php" (Constant static value)

   1:  <html>

   2:  <head>

   3:  <title> Using constants </ title>

   4:  <head>

   5:  <body>

   6:  <? Php

   7:  define ("CAMPUS", "STMIK AMIKOM YOGYAKARTA");

   8:  define ("SLOGAN", "COLLEGE PLACE PEOPLE tie");

   9:  print "CAMPUS". CAMPUS;

  10:  echo "<br> SLOGAN:". SLOGAN;

  11:  ?>

Variable

2011-04-19T22:59:00.001+07:00

In every programming language we will certainly encounter the concept of variable.Variable is a place in memory to store data whose value can be changed during program run.In PHP, every variable always begins with the sign '$' and followed by the name of the variable, regardless of whether the data is integer, real or string, PHP will automatically convert the data according to type. Variable names can be any combination of letters of the alphabet and numbers with a maximum length of 32 characters. But unlike in most other programming languages that require us to declare variables in advance, variables in PHP do not have to be declared before the variable is used. Varabel represented by certain words with the rules of writing as follows:

1. Variables begin with a dollar sign ($).
2. The length is unlimited.
3. It should begin with the letter or underscore (_). The next character can only contain letters, numbers, and certain characters are allowed (ASCII characters from 127-255).
4. May not use punctuation.
5. Case sensitive or uppercase and lowercase letters are different.
6. Do not use a word that is the built-in PHP.
7. No need to be declared
8. Can not contain spaces.
Examples of Variables:
True False
 $ _name
 $ first_name
 $ name3
 $ name_3
 $ 3name
 $ name?
 $ first + name
 $ first.name
 $ first name
In addition to the above matters, there are still some more criteria to consider
in writing the PHP script as follows:
a. Each page that contains PHP script must be saved with the extension PHP
according to the PHP program that supports it. For example: nama_file.php, or
nama_file.php3, or nama_file.php4.
b. Each script must be preceded by an opening PHP PHP (<? Php etc.) and
then concluded with closing (?>).
c. Each line of the script content should be preceded by a print statement like write in Pascal,
the Print and Echo. Writing criteria are as follows:
 Print ("The order")
 printf ("The order");
 Echo "The order";
 Echo command
d. Each end of the command line must end with a semicolon (;). Suppose we would write "Hahan", then the script to be written is: <? php print ("haha");?>.

Visual Basic ??????????

2011-04-15T16:00:00.000+07:00

Visual Basic is one of object-oriented programming languages (Object Oriented Programming / OOP) is very easy to use and learn. Visual Basic is produced by Microsoft Corporation which also produces the Windows operating system with windows kompetibelitas So good level.
Visual Basic compiler file applications will have:
1. Project Files (*. vbp)
Project file is a file from the application that we build itself. In this project file usually consists of several other files.
2. The file interface / form (*. frm)
This file is the file that stores information about the form in an application form. In a regular project file consists of more than one form.
Design Time and Runtime
In visual programming, there are two times that show what we can do at that moment in our application.
1. Design Time
Design Time is the time when we are designing / building our application. Determining the shape of interface, type the program code, and all the activities of design / development do we do when the design-time.
2. Run Time
We run or execution results of the design we have done is the Runtime. At this time we can not alter the program code.

Come to Know PHP

2011-04-15T15:23:00.001+07:00

Did you know that PHP
1. Is a recursive acronym of P HP: Hypertext Prepocessor.
2. First created by Rasmus Lerdorf in 1994.
3. Must be written in between the tags:

a. Style XLM
<?php
echo ”Style XML”
?>
b. Short Style
<?
Echo”ShortStyle”;
?>
c. Style SCRIPT
<script language =’php’>
echo ”Style JavaScript”;
</script>
d. Style ASP
<%
echo ”Style ASP”
%>

4. Every single statement (command) usually end with a semicolon (;)
5. Case sensitive to the name created by the user identifier (a variable, constants, functions, etc.), but NOT case sensitive to the built-in identifier of PHP. So:

$haha ≠ $Haha ≠ $HAHA
calculateArea() ≠ CalculateArea()
echo = ECHO
while = WHILE

6. Easy to learn

Say Hello to the PHP
1. Enter this command in notepad or dreamweaver.
<? php
echo "Hello, my name is PHP";
?>
2. Save with the name DocumentRoot hello.php on your computer.
3. Open the browser and then typing http://localhost/hello.php
4. See the results in the browser.

PHP Basic Structure

2011-04-15T15:02:00.000+07:00

PHP Definition

According to official documents of PHP, PHP stands for PHP Hypertext Preprocessor. It is a form of language scripts that are placed in the server and processed on the server. The results are sent to the client, where the user uses browser. PHP is a server-side scripting language that integrates with HTML for create dynamic web pages. The purpose of the server-side scripting is the syntax and the commands that we give will be entirely run on the server but included in regular HTML documents. PHP is free to use. You do not have to pay anything for Using this software, aka free. You can download it via the site http://www.php.net. PHP is available in the form of binary code or source code complete.

PHP Style

PHP gives us flexibility when writing programs, with notes still refers to the conditions set. Please note that by the time PHP parse the file, the tag will be read to meet the special tags which tell for menerjemahkanya as PHP code. If the tag is found, then parser to execute the program code until the end on the closing tag. This also applies to the PHP code is embedded in HTML documents, which the parser will find the tags to be found. The rest are outside the tags will be considered not a PHP code, so the parser is also no need to process it. There are four ways to write a tag that identifies the PHP program.

Introduction to Web Server and Server Side Scripting

2011-04-15T14:43:00.000+07:00

1.1 Web Server
Web Server is a server software that functions in received a request (request) in the form of web pages via HTTP or HTTPS from clients, known as a web browser and sent back (response) results in the form of web pages are generally in the form of an HTML document.

Some of the widely used Web Server on the Internet, among others:
1. Apache Web Server (http://www.apache.org)
2. Internet Information Services, IIS (http://www.microsoft.com/iis)
3. Xitami Web Server (http://www.xitami.com)
4. Sun Java System Web Server (Http://www.sun.com/software/products/web_srvr/home_web_srvr.xml)
1.2 Server Side Scripting
Server Side Scripting is a scripting or programming technology web in which the script (program) is compiled or translated on the server. With server side scripting, enabling it to generate dynamic web pages.
Some examples of Server Side Scripting (Programming):
1. ASP (Active Server Pages) and ASP.NET
2. ColdFusion (http://www.macromedia.com/software/coldfusion)
3. Java Server Pages (http://java.sun.com/products/jsp/)
4. Perl (http://www.perl.org)
5. Phyton (http://www.python.org)
6. PHP (http://www.php.net)
Advanced Web Programming
PHP Privileges
1. Fast
2. Free
3. Easy to learn
4. Multi-platform
5. Support technical-support
6. Many of the PHP community
7. Safe
1.3 Installing Apache, PHP and MySQL with XAMPP
The process of installing Apache, PHP and MySQL is often a constraint, especially
for beginners just learning web programming with PHP. This caused
because the software must be installed and configured one by one. For those not yet
understand correctly, would often have difficulty, especially for us who study
independent.
But do not be discouraged, many available applications packages
The third brings together the software (Apache, PHP and MySQL) into a single installer.
The installation can be done easily and quickly, just next, next,
and finish.
Some application packages include:
1. XAMPP (Windows version) and lampp (Linux version) which can be downloaded at
http://apachefriends.org.
2. WAMP Server.
3. AppServ.
4. PHPTriad.

VARIABLE, VAL and constants in visual basic

2011-04-13T22:23:00.004+07:00

VARIABLE, VAL and constants

VARIABLE

The variable is a place in memory that is named (as an identifier) and allocated to accommodate the data.

Syntax: As Type Dim name of the variable data

Example: Dim a As Integer

Dim name As String

Naming rules of variables in Visual Basic is:

1. No more than 40 characters

2. Consisting of letters, numbers and underscore (_)

3. The first character must be a letter

4. May not use words that are defined by visual basic (reserved word)

How to put variable to the source code:

a) In General

If the variable is placed on the General then these variables can be read on eachprocedure in a Form.

b) In Procedure

If the variable is placed on the procedure in each object, then the variable can only be read on the procedure alone (no other procedure can be read at even the one from).

c) In Module

If the variable is placed in Module then these variables can be read or be called onevery procedure in a single project.

VAL

Val or value is used if we do not declare a variable, or to convert or change the datatype string to type numeric data.

Constant

Constants together with the variables but constants have fixed values or characterconstant. Declare the constants in Visual Basic using the Const [a constant] As [data type of the constant] = [value constants].

Example of declaring a constant:

Const Phi As Integer = 3:14
