XML , XSLT and XPATH Questions

2011-02-19T21:10:00.002+11:00

1) 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

2) Example of XML

<note>
<to>Tove</to>
<from>Jani</from>
<heading>Reminder</heading>
<body>Don't forget me this weekend!</body>
</note>

3) XML must have root element

4) Entity reference

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

5) Comments in xml

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

6) White space is preserved in xml

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

7) 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
text
attributes
or a mix of all of the above...

<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. <book> also has an attribute (category="CHILDREN"). <title>, <author>, <year>, and <price> have text content because they contain tex

8) XML attribute

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 can be important to the software that wants to manipulate the element

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

9) What is well formed xml and valid xml

XML with correct syntax is "Well Formed" XML.

XML validated against a DTD is "Valid" XML.

10) XML DTD

<!DOCTYPE note
[
<!ELEMENT note (to,from,heading,body)>
<!ELEMENT to (#PCDATA)>
<!ELEMENT from (#PCDATA)>
<!ELEMENT heading (#PCDATA)>
<!ELEMENT body (#PCDATA)>
]>

11) 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>

12) XSLT example

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

<xsl:for-each select="breakfast_menu/food">

- <xsl:value-of select="price"/>

</div>

<xsl:value-of select="description"/>

<xsl:value-of select="calories"/> (calories per serving)

</span>

</div>

</xsl:for-each>

</body>

</html>

13) XMLHttpRequest

The XMLHttpRequest object is used to exchange data with a server behind the scenes.

The XMLHttpRequest object is a developer's dream, because you can:

Update a web page without reloading the page

Request data from a server after the page has loaded

Receive data from a server after the page has loaded

Send data to a server in the background.

14) Manipulating html using xml

<html>

<body>

<h1>W3Schools Internal Note</h1>

<div>

<b>Message:</b> <span id="message"></span>

</div>

if (window.XMLHttpRequest)

{// code for IE7+, Firefox, Chrome, Opera, Safari

xmlhttp=new XMLHttpRequest();

}

else

{// code for IE6, IE5

xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");

}

xmlhttp.open("GET","note.xml",false);

xmlhttp.send();

xmlDoc=xmlhttp.responseXML;

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;

</script>

</body>

</html>

Note.xml is the following

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

<note>

<heading>Reminder</heading>

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

</note>

15) CDATA

Everything inside a CDATA section is ignored by the parser.
A CDATA section starts with "<![CDATA[" and ends with "]]>”

16) XPATH

Nodes

In XPath, there are seven kinds of nodes: element, attribute, text, namespace, processing-instruction, comment, and document nodes.

XML documents are treated as trees of nodes. The topmost element of the tree is called the root element.

Look at the following XML document:

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

<bookstore>
<book>
    <title lang="en">Harry Potter</title>
    <author>J K. Rowling</author>
<year>2005</year>
    <price>29.99</price>
</book>
</bookstore>

Example of nodes in the XML document above:

<bookstore> (root element node)

<author>J K. Rowling</author> (element node)

lang="en" (attribute node)

17) Selecting Nodes

nodename	Selects all child nodes of the named node
/	Selects from the root node
//	Selects nodes in the document from the current node that match the selection no matter where they are
.	Selects the current node
..	Selects the parent of the current node
@	Selects attributes

18) Xpath example

<html>

<body>

function loadXMLDoc(dname)

{

if (window.XMLHttpRequest)

{

xhttp=new XMLHttpRequest();

}

else

{

xhttp=new ActiveXObject("Microsoft.XMLHTTP");

}

xhttp.open("GET",dname,false);

xhttp.send("");

return xhttp.responseXML;

}

xml=loadXMLDoc("books.xml");

path="/bookstore/book/title"

// code for IE

if (window.ActiveXObject)

{

var nodes=xml.selectNodes(path);

for (i=0;i<nodes.length;i++)

{

document.write(nodes[i].childNodes[0].nodeValue);

document.write("<br />");

}

// code for Mozilla, Firefox, Opera, etc.

else if (document.implementation && document.implementation.createDocument)

{

var nodes=xml.evaluate(path, xml, null, XPathResult.ANY_TYPE, null);

var result=nodes.iterateNext();

while (result)

{

document.write(result.childNodes[0].nodeValue);

document.write("<br />");

result=nodes.iterateNext();

}

</script>

</body>

</html>

XML used in this example

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

<bookstore>

<book category="COOKING">
<title lang="en">Everyday Italian</title>

Javascript Tutorial

2011-02-19T20:08:00.005+11:00

Javascript Totorial

1) What is Javascript

JavaScript is THE scripting language of the Web.

JavaScript is used in billions of Web pages to add functionality, validate forms, comunicate with the server, and much more.

JavaScript was designed to add interactivity to HTML pages
JavaScript is a scripting language
A scripting language is a lightweight programming language
JavaScript is usually embedded directly into HTML pages
JavaScript is an interpreted language (means that scripts execute without preliminary compilation)
Everyone can use JavaScript without purchasing a license

2) Example – using javascript directly

<h1>My First Web Page</h1>

</body>
</html>

3) Example – using javascipt in the function

<html>

<head>
<script type="text/javascript">
function displayDate()
{
document.getElementById("demo").innerHTML=Date();
}
</script>
</head>

<body>

<h1>My First Web Page</h1>

<button type="button" onclick="displayDate()">Display Date</button>

</body>
</html>

4) Example – using an external javascript

5) Comments in javascript

Both single line comments // and multiple line comments are supported /* */

6) Declaring variables

var x=5;
var carname="Volvo"

if you donnt declare a variable it will be automatically created in the global scope

x=5;
carname="Volvo";

7) Declaring array

var myCars=new Array(); // regular array (add an optional integer
myCars[0]="Saab"; // argument to control array's size)
myCars[1]="Volvo";
myCars[2]="BMW”;

8) The navigator object contains the information about the visitors browser

<div id="example"></div>

<script type="text/javascript">

txt = "<p>Browser CodeName: " + navigator.appCodeName + "</p>";
txt+= "<p>Browser Name: " + navigator.appName + "</p>";
txt+= "<p>Browser Version: " + navigator.appVersion + "</p>";
txt+= "<p>Cookies Enabled: " + navigator.cookieEnabled + "</p>";
txt+= "<p>Platform: " + navigator.platform + "</p>";
txt+= "<p>User-agent header: " + navigator.userAgent + "</p>";

document.getElementById("example").innerHTML=txt;

</script

9) Settimeout and cleartimeout functions

var t=setTimeout("javascript statement",milliseconds);

clearTimeout(setTimeout_variable);

10)Creating objects

personObj=new Object();
personObj.firstname="John";
personObj.lastname="Doe";
personObj.age=50;
personObj.eyecolor="blue";

11) Practical example of adding two numbers in javascript

<html>
<head>
<title>Form to sum two numbers</title>
<script type="text/javascript">
function displaysum()
{
var f = parseInt(document.getElementById("first").value);
var s = parseInt(document.getElementById("second").value);
document.getElementById("answer").value = f+s;
}
</script>
</head>
<body>
<br/>
Value1 = <input type="text" id ="first"></input>
<br/>
Value2 = <input type="text" id ="second"></input>
<input type="button" id="submit" onclick="displaysum()" value="Submit"></input>
<br />
Answer = <input type="text" id="answer"></input>
</body>
</html>

Tutorial HTML and CSS

2011-02-12T10:37:00.000+11:00

Tutorial HTML , CSS

HTML

1) Who makes Web standards?

World Wide Web Consortium makes web standards.

There website is w3.org

2) What is the latest version of HTML?

HTML 5.

3) Write a basic HTML to display “Hello World”?

<html>

<head>

</head>

<body>

<p>

Hello World

</p>

</body>

</html>

4) What is HTML?

HTML is a language for describing web pages.

HTML stands for Hyper Text Markup Language
HTML is not a programming language, it is a markup language
A markup language is a set of markup tags
HTML uses markup tags to describe web pages

The purpose of a web browser (like Internet Explorer or Firefox) is to read HTML documents and display them as web pages. The browser does not display the HTML tags, but uses the tags to interpret the content of the page:

5) How to display HTML links?

<a href = “http://www.source.com”> This is a link to the website.</a>

6) How to display an image?

7) How to put a line break?

<br/>

8) What are HTML attributes?

HTML elements can have attributes

Attributes provide additional information about an element

Attributes are always specified in the start tag

Attributes come in name/value pairs like: name="value"

Example href is an attribute in the example below:-

<a href = “http://www.source.com”> This is a link to the website.</a>

9) Write down some common attributes?

Below is a list of some attributes that are standard for most HTML elements:

Attribute	Value	Description
Class	classname	Specifies a classname for an element
Id	id	Specifies a unique id for an element
Style	style_definition	Specifies an inline style for an element
Title	tooltip_text	Specifies extra information about an element (displayed as a tool tip)

10) How to create horizontal lines.

HTML Lines

The <hr /> tag creates a horizontal line in an HTML page.

11) How to write comments in HTML?

12) HTML Output important point

You cannot be sure how HTML will be displayed. Large or small screens, and resized windows will create different results.
With HTML, you cannot change the output by adding extra spaces or extra lines in your HTML code.
The browser will remove extra spaces and extra lines when the page is displayed. Any number of lines count as one line, and any number of spaces count as one space.

13) Give some Text formatting example?

<html>

<body>

<p><strong>This text is strong</strong></p>

<p><em>This text is emphasized</em></p>

<p><i>This text is italic</i></p>

<p><small>This text is small</small></p>

<p>This is<sub> subscript</sub> and <sup>superscript</sup></p>

</body>

</html>

14) Examples of style attribute

<html>

<body>
<h1 style="font-family:verdana">A heading</h1>
<p style="font-family:arial;color:red;font-size:20px;">A paragraph.</p>
</body>

</html>

15) How to open the link in new browser window

<a href="http://www.source.com/" target="_blank">Visit Source</a>

16) How to specify an anchor in html

The name attribute specifies the name of an anchor.

<a name="tips">Useful Tips Section</a>

Create a link to the "Useful Tips Section" inside the same document:

<a href="#tips">Visit the Useful Tips Section</a>

Or, create a link to the "Useful Tips Section" from another page:

<a href="http://www.w3schools.com/html_links.htm#tips">
Visit the Useful Tips Section</a>

17 ) How to define a table element?

<table border="1">
<tr>
<th>Header 1</th>
<th>Header 2</th>
</tr>
<tr>
<td>row 1, cell 1</td>
<td>row 1, cell 2</td>
</tr>
<tr>
<td>row 2, cell 1</td>
<td>row 2, cell 2</td>
</tr>
</table>

17) How to define a form element.

<form name="input" action="html_form_action.asp" method="get">
Username: <input type="text" name="user" />
<input type="submit" value="Submit" />
</form>

18) How to define radio buttons.

<form>
<input type="radio" name="sex" value="male" /> Male<br />
<input type="radio" name="sex" value="female" /> Female
</form>

19) What is a DocType?

The doctype declaration is not an HTML tag; it is an instruction to the web browser about what version of the markup language the page is written in.
The doctype declaration refers to a Document Type Definition (DTD). The DTD specifies the rules for the markup language, so that the browsers render the content correctly.
The doctype declaration should be the very first thing in an HTML document, before the <html> tag.

Example:-

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<title>Title of the document</title>
</head>

<body>
The content of the document......
</body>

</html>

20) Some elements that can be defined in the head section of html

The following tags can be added to the head section: <title>, <base>, <link>, <meta>, <script>, and <style>.

21) What is a meta data

Metadata is information about data.
The <meta> tag provides metadata about the HTML document. Metadata will not be displayed on the page, but will be machine parsable.
Meta elements are typically used to specify page description, keywords, author of the document, last modified, and other metadata.
The <meta> tag always goes inside the head element.
The metadata can be used by browsers (how to display content or reload page), search engines (keywords), or other web services

Examples

22) Some useful entities to display spaces, less than etc.

Note: Entity names are case sensitive!

Result	Description	Entity Name	Entity Number
	non-breaking space
<	less than	<	<
>	greater than	>	>
&	ampersand	&	&
¢	cent	¢	¢
£	pound	£	£
¥	yen	¥	¥
€	euro	€	€
§	section	§	§
©	copyright	©	©
®	registered trademark	®	®
™	trademark	™	™

23) What is XHTML

XHTML stands for EXtensible HyperText Markup Language

XHTML is almost identical to HTML 4.01

XHTML is a stricter and cleaner version of HTML

XHTML is HTML defined as an XML application

XHTML is a W3C Recommendation

CSS

1) Inline style

2) Style inside the head element

<html>

<head>

{

color:red;

text-align:center;

}

</style>

</head>

<body>

<p>Hello World!</p>

<p>This paragraph is styled with CSS.</p>

</body>

</html>

3) External Style sheet

MBA options available in sydney for working IT professionals.

2010-10-02T21:16:00.004+10:00

After the super success of my earlier articles, I thought of writing a comprehensive article(everything in one place) regarding various MBA options available for working IT professionals in sydney. I am writing this, considering the four universities in sydney namely University of New South Wales, Macquarie University, University of Sydney and University of Technology.
1) Let us start with University of New South Wales.
Here is the link to get more information
http://www.asb.unsw.edu.au/futurestudents/postgraduate/agsmmba/mbaexecutive/Pages/default.aspx
This university has the Executive MBA program. The campus is at Kensington in sydney city.
The name of the department is AGSM(Australian graduate School of Management) The Executive MBA program is designed for the working people. It is divided into two parts, first is the Graduate Diploma in Management (GDM) and then the Strategic Management Year(STY). The GDM has 6 core subjects and 2 elective subjects and the STY has four subjects to pass. You need to have 65% marks in the GDM to move on to the STY. The classes are held in the evening after work and during the weekend. The fees is the following:-

GDM - 3450 per subject = 27600 and the STY is 34490.
You can apply for the recognition of prior learning such that if you have done some of the subjects in the undergraduate degree you can get exemption for some of the subjects. The entry criteria is 2 years of management experience with an undergraduate degree or 6 years of industry experience. It is quite flexible such that you can take a leave from the course and then join back again. The STY is done in residential mode, which is 5 days per subject therefore it is 4 times 5 day residential arrangement. Exchange programs are available with other universities such that students can go to hong kong or london or other places under this program.
There is a slightly different degree designed for IT professionals which is called Masters of Business and Technology(MBT). It is designed for working IT professionals who want to get a formal education in Business. Fees is 2900 per subject and you need to complete 12 subjects out of the total of 20 subjects. Therefore you can choose your own subjects and tailor the degree as per your interest. It is done mainly in online mode with face to face option available once a week. Entry criteria is 4 years of experience alongwith undergraduate degree.
Other option available is Graduate Certificate in Change Management.
2) Let us talk about the MBA option at macquarie university.
More info at the following link.
http://www.mgsm.edu.au/wps/wcm/connect/Internet/Root/executive/
The name of the department is

Macquarie Graduate School of Managment(MGSM). The MBA option is available at north ryde and the campus at sydney city. Macquarie does not have an executive MBA option but it has a MBA option which can be done in part time mode. It has more subjects than the Executive MBA. There is a total of sizteen subjects to clear.Entry criteria is 5 years of managerial experience alongwith an undergraduate degree. The classes are held during the evening, one subject 6-10PM once a week. There is an option of block class also, which is held full day on sat and sun. The degree is divided into certificate(total 3 subjects), diploma(total 6 subjects) and degree (total 16 subjects). It is divided into core subjects and elective subjects. The fees is approx 3500 per subject. It is flexible such that you can take leave if the situation changes and then join back again.
Other degrees available are Masters in management in sustainable leadership and Masters of management in people and performance.
3) The University of Technology conducts its courses on its campus near the central station.
http://www.gsb.uts.edu.au/courses/master.html
It has two main options available. MBA which can be done in part time mode and the Executive MBA program. MBA program has 16 subjects and EMBA has 12 subjects. The fees is as follows: MBA is 2795 per subject and EMBA is 3978 per subject. The classes are held during the evening and there is an option to do it during the weekend as well. The entry requirement is 4 years of managerial experience with an undergraduate degree.
The other degrees available are Master of Quantitative Finance programs, Master in professional Accounting program.
4) The University of Sydney has the degree which is called Global MBA. The total fees is 85000. The entry criteria is undergraduate degree alongwith 10 years of experience. It is a slightly different program from the other universities. More info is in the following link.
http://sydney.edu.au/business/globalEMBA

Now the million dollor question is that from where will the money come.
There are various options.
- Fee help is available for citizens .
- Some universities give scholarships.
- Some companies sponsor the program for its employees.

But the question that you need to ask yourself is that whether you are ready to give a commitment of 8 to 10 hours per week. MBA is often called Marriage Breaker, therefore you need to do efficient time management for yourself. MBA can certainly empower you with the knowledge such that you will have have an edge than your counterparts. The other advantage is that your class will consist of mature like minded people. It is an excellent platform to network with other professionals and learn from each other. Work experience is a mandatory part of the entry criteria, this is because the university wants students to bring in real life work experience with them such that the students can learn from each other and then go back and apply there enhanced knowledge in there work place.
With this note, I end this article. Please comment on this article or email me at rsaini77@gmail.com. I can certainly help you with more information regarding this topic.

Guide and Suggestion for people migrating with kids and family to sydney from worldwide.

2010-09-24T23:08:00.004+10:00

Hi,
After the overwhelming response from world over to my previous article Ten step guide for people migrating worldwide to Sydney, Australia. (http://rsaini77.blogspot.com/2010/09/informative-article-regarding-people.html),
i have been asked to write an article for people who are migrating with families to sydney.

So here I go with this article. First I will talk about the different type of child care facilities that are available in sydney. The basic child care/day care cost to send your child is around 80 dollors per day. There are some family day care centres as well, which cost around 55 dollors per day. Child care is divided into three groups. Kid with age 0-2 years, 2-3 years and 3-5 years. The child care with 0-2 years is very hard to find and some have a waiting of nearly 6 months. It is best to fill out the forms when the child is born if you plan to send him/her to child care in 6 months time. 2-3 and 3-5 are available and it is best to start with one day per week and then gradually go upto five day per week, depending upon how the child is adjusting to the new centre. Nappies and food, milk etc are all covered in the fees as described above. Now about the fees, if the combined income of the family (husband and wife ) is more than 100K per annum, then you donn't get any daily rebate from the government, but you can still claim the child care rebate at the end of the financial year. Therefore for example if you pay at the rate of 80 dollors per day, then you pay 20800 in a year for the childcare, then you can claim 50% of this amount(capped at 7500 per annum). Therefore you pay the total of 13300 from your pocket per annum. In case the family(husband and wife) earns less than 100K per annum, then you get a rebate of approx 20 dollors per day in addition to the above.

Therefore annually you pay 60 * 5 days * 52 weeks = 15600 - 7500 = 8100 from your pocket.
Family day care center is like the child care center but it is run by the lady in the house and she cannot employ anyone else. Therefore a lady can get a permission to run a family day care and keep upto 5 children during the day. You get the same type of rebates as explained above.
Now let me explain about the kids who are above 5 years of age. Kids from 5 to 12 years go to primary school, which is from kindergarten to year 6. How goo dhte primary school will be depends on the area where you live. There are various websites which give ratings to the primary schools, therefore you can see the ratings of your local school to find out how good is the school. Now the interesting point is that the school is until 3:00 PM only, therefore if the couple is working until 6pm, then you have to find a school which has after school facility. One point to mention is that every school has an area allocated to it, such that it can take admit students from that particular locality only. Therefore it is quite possible that your house is allocated to one school and the house opposite to you is allocated to a different school. Therefore it is best to go to the website of the school and see if you are under its area or not. But having said that, no one is stopping you from applying at various other schools. The only point is that you should have a valid explanation in doing so, such as the school is near your area of work, it is on the way to work or some other explanation. Other than the govt. primary school, there are catholic schools and private schools. Catholic schools are strictly for catholic religion people and they are considered as good schools. Private schools are for people who have loads of money and don't have other places to spend money. Therefore they can send there children to private schools and then have regular kitty parties and parent get together with other rich people through rich social school networking.
Now let us talk about kids from class 7 to class 12. There are various options available. You can go to your local area high school. Other option is that you can sit for selective school entrance test in year 6 and if you clear it, you can go to selective schools in sydney.

Now the concept of selective school is that some schools are marked as selective, which means that kids who are god gifted in intelligence can go to that school and can learn particular subjects or can learn along with other like minded intelligent kids.
How to inject intelligence into your kid or how to make him intelligent even if not god gifted, needs an article on its own.
I hope you will enjoy this article and if i missed something you can always email me at rsaini77@gmail.com or write a comment regarding this article.
Thanks for your time.
Happy Blogging.

Ten step guide for people migrating worldwide to Sydney, Australia.

2010-09-12T09:41:00.001+10:00

Hi,
Let me first introduce myself. I am Rajeev Saini (rsaini77@gmail.com) working as an engineer in Siemens in sydney.
From linkedin groups , I see that many people are migrating from USA/Europe/Russia to sydney and they have many questions, therefore thought of writing an informative article about this place.
No doubt, sydney is a great place to work and stay. It has got almost everything, let me list down some of its characteristics:-
- Pleasant weather, no extremes.
- Beaches
- Mountains
- Great city life.

Now for the people that are migrating here, sydney can be divided into the following:-
Pls open up google maps http://www.google.com.au/maps and type sydney into it.
- East sydney, with suburbs like rockdale, padington, bondi,etc
- North sydney, with suburbs like hornsby, chatswood.
- West sydney, with suburbs like parramatta, blacktown
- South sydney, with suburbs like ingleburn, liverpool.
- Inner sydney, with suburbs like strathfield, burwood etc.

Hope you have found these suburbs on the map by now, therefore if you are planning to come here, the following is the general guideline of each part of sydney
East sydney - this area is regarded as the most expensive and fit for the affluent people.
It is close to the beaches and linked by buses to central part of sydney.
North sydney - this area is also close to the beaches and most of the computing jobs are concentrated in this area, with major companies having offices in chatswood, st leonards, noth ryde etc.
West sydney - it is generally regarded as the crime capital of sydney, it is linked to the central sydney by train network, has lot of asian population and caters to the needs of the people from asian countries.
South sydney - Generally not very well connected to central sydney, but can cater to the needs of the people who are low on budget . you can find cheaper accomodation and low rentals in this part of sydney.
Inner sydney - Is the place where most of the migrants land up, it is high in rental and is the most connected part of sydney, therefore if you get an interview call, you can generally be ready and can reach the interview place within 20 minutes.

For the people coming from USA, the major difference that you will find here is that train journey is given utmost importance here in sydney.People in USA generally go by car and consider 30 km to be a close enough area. Therefore they need to get out of this mindset after coming here, you will see that some rental accommodations in the same suburb fetch more rental income (or you need to pay more rent) if they are next to train station. And by the way 30 kms either way of central sydney is either forest or deep water, therefore donn't consider 30 km to be close enough.
People coming from europe will find that the train network is same as that of there home country.

The other difference is that sydney is much more expensive than compared to USA. I have realised that it is due to less competition in any chosen field. Therefore a person residing in USA will laugh if i him the following-
1) There are only 2 major superstores here, namely woolworths and coles.
2) There are only 4 major banks here, though none collapsed during GFC.
3) Ginger in sydney is about 15 AUD per kg. Therefore pls bring some ginger alongwith from your home country.
4) Banks charge 5 AUD a month to keep your money.
5) Home loan rate is about 7%.
6) Bread cost is about 5 AUD per bread.
7) Rental is about 400 AUD per week.
8) There are 3 major job search sites and 3 major car buying sites.
9) Train journey is expensive, a peak hour ticket can cost you about 10 AUD a journey from say parramatta to north sydney.
10) Leather goods cost a lot here, therefore buy your leather jackets before coming.

There are many other points, therefore if you like this article, i will come up with more info in my next article.
To summarise some more points:-
If you land up as a permanent resident there, there are loads of things to do in first month:-
1) Apply for medicare card, so that you can go to a GP doctor without any charges.
2) Go to centrelink office, to get some financial assistance if you are eligible.
3) Find a rental accomodation depending upon where you want to live.
4) Make a monthly or quaterly rail pass.
5) Register with the job agents.
6) Get a tax file number.
7) Apply for a learner driving test or find out whether your home country license is valid here.
8) Prepare to say mite, slang for mate.
9) Find cheaper chinese shops in your local area so that you get used to chinese stuff as it will become part of your life.
10) Open a bank account and deposit your cheques or cash that you have brought alongwith from your home country. It is no brainer, there are only 4 banks here and they rip you off in similar way.

ATL/COM - Passing UDT in an IDL file.

2010-09-06T14:44:00.000+10:00

There are two general scenerios that needs to be discussed.
1) The user wants to put an array field inside a structure, something like
struct DVDStructure
{
SAFEARRAY(long) *m_dvdID;
BSTR m_comment;
}

To put elements into this safearray, you need to create a safearray using the function

SAFEARRAY *dvdArr;

dvdArr = SafeArrayCreateVector(VT_INT, 0, len);
// iterate and put elements into this safearray.
SafeArrayPutElement()

To get the elements from this safearray,
SafeArrayGetLBound();

SafeArrayGetUBound();
//iterate from lbound to ubound and then get the element.
SafeArrayGetElement();

2) The user wants to pass the array of UDT from the IDL file.

HRESULT PassStructure([out, retval]SAFEARRAY(struct CdvdGenStruct) *vecObjects);

The structure needs to be defined in the library section of the idl file(if you donn't follow this you get element not found error at runtime) .
[uuid(give a guid here)]

struct CdvdGenStruct
{
long m_id;
BSTR m_comments;
};

HRESULT hr = GetRecordInfoFromGuids(LIBID,
1, 0, 0x409, __uuidof(CdvdGenStruct),
&pRecInfo);

// Create SafeArray
SafeArrayCreateEx(VT_RECORD, 1, rgbounds, pRecInfo);
hr = SafeArrayAccessData(CdvdGenStruct,(void **)&actualData);
// put the data inside this safearray
hr = SafeArrayUnaccessData(CdvdGenStruct);

Whereever you need to access the data , simply do
SafeArrayAccessData(*vecObjects,(void **)&pActualData);
and then use the pActualData.

In case , you have a UDT inside a UDT that needs to be passed through IDL file, then the inner UDT also needs to have a GUID of its own.
