Mengizinkan SQL Browser pada Firewall di posisi on

2013-07-21T19:53:00.000-07:00

Saat anda menggunakan Service Sql browser dan menggunakan port dinamis ,dengan tujuan agar instance database anda bisa diakses oleh komputer lain (client) maka biasanya di Sistem Operasi Windows ex. 8 anda pasti mematikan fungsi Firewall windows anda agar koneksi antar komputer tetap bisa berjalan. Lalu apakah harus selalu mematikan Firewall WIndows anda untuk melakukan koneksi ke Sql Database dari komputer lain (client) ? padahal seharusnya firewall juga memiliki fungsi penting untuk memproteksi komputer anda.

Untuk mengatasi hal ini (Firewall tetap hidup/On) dan tetap bisa mengakses instance database dari komputer lain, berikut langkah-langkah mudahnya : 1. Buka control Panel dan Pilih System and Security-Windows Firewall dan pilih "Advance Setting",

2. Akan muncul "Windows FIrewall Advance Security" , di panel bagian kiri pilih "inbound Rule" - klik kanan dan pilih "new rule"

3. Karena kita akan mengizinkan Service SQL Browser, maka kita pilih "Program" dan pilih "next",
4. Selanjutnya Pilih "This Program Path", dan Browse di

SQL Browser service di C:\Program Files (x86)\Microsoft SQL Server\90\Shared\sqlbrowser.exe (note the "(x86)").

5. Pilih "Allow the connection" dan "Next"

6. Terakhir, di Profile Silahkan isikan Nama Rule (Terserah) misalnya SQLBrowserx86, dan isikan deskripsi mengenai rule tersebut. dan "FINISH"

Catatan : anda juga bisa melakukan hal yang sama baik program(exe) ataupun port agar bisa dilalui oleh Firewall Windows anda dengan cara yang kurang lebih sama dengan langkah diatas. Semoga membantu...

Dilakukan pengujian dengan Windows 8 64 Bit, dan SQL SERVER 2008 Express Edition R2

3. Pilih "Remove" dan ikuti langkah-langkah wizardnya (mirip seperti saat anda menginstall sebuah instance) bedanya hanya saat ini ada pilihan instance mana yang akan di remove ex. dlm hal ini kita pilih "SQLSIPMEN" :

4. Pilih Next ,

5. Ikuti Wizardnya hingga selesai. Sekarang cek "SQL Server Configuration Manager " Anda dan instance SQLSIPMEN yg tadi kita remove sudah tidak ada pada list instance... Semoga membantu.. dan bisa lebih meringankan beban memory anda ..

SQL SERVER BROWSER TIDAK BISA START (windows 8 )

2013-07-20T02:38:00.002-07:00

Jika anda sedang menggunakan Database sql server express 2008 supaya bisa diakses oleh computer lain / sharing, maka Service SQL Browser harus di aktifkan terlebih dahulu, tetapi terkadang ada beberapa hal yang menyebabkan service tersebut tidak bisa diaktifkan diantaranya "The SQL Browser service port was unavailable for listening, invalid" alias port yang digunakan sudah dipakai oleh service yang lain sepert Sqlserv.exe atau service SQL Server yg lainnya.

secara default SQLBrowser akan menggunakan UDP/port 1434, cara mengeceknya apakah port 1434 sudah/sedang dipakai silahkan gunakan command prompt dan ketikkan " netstat -aon -p UDP "

misalnya akan muncul seperti ini :

Proto Local Address          Foreign Address        State           PID
UDP    0.0.0.0:445            *:*                                    4
UDP    0.0.0.0:500            *:*                                    1156
UDP    0.0.0.0:1025           *:*                                    1792
UDP    0.0.0.0:1026           *:*                                    1792
UDP    0.0.0.0:1027           *:*                                    1792
UDP    0.0.0.0:1434           *:*                                    4736

artinya UDP 1434 sedang dipakai oleh service dengan PID 4736 , sekarang untuk mengetahui service apa silahkan anda buka TASK MANAGER (ctrl+alt+del) dan pilih tab "services,

Perhatikan PID dan apa Name Servicenya, jika itu adalah Service SQL Server lainnya silahkan matikan untuk sementara terlebih dahulu.

Selanjutnya coba sekarang anda coba untuk "Start" SQL Browser kembali menggunakan SQL Server Configuration Manager dan tes koneksi dari computer client, semoga bisa mengatasi masalah anda. :)

Mengaktifkan Koneksi Antar Komputer ke SQL Server Express 2008 (Win 8)

2013-07-20T02:09:00.001-07:00

berdasarkan pengalaman pahit dalam melakukan koneksi via aplikasi Data Entry Susenas (Milik BPS) yang menggunakan database sqlserver (express edition 2008) dari satu computer (client) ke computer (server) dgn OS windows 8, karena itu saya mencoba untuk membuat catatan supaya kejadian ini tidak terulang lagi, saat saya melakukan instalasi aplikasi-aplikasi lainnya.

Pada dasarnya untuk menghubungkan computer (client) ke database Sqlserver pada Computer (server) ada dua hal yang harus di lakukan (Asumsi jaringan antar computer sudah tidak ada masalah):

1. SQLBrowser Service harus aktif, caranya gunakan command prompt dan ketikkan "net start sqlbrowser" (tanpa tanda petik). Untuk menghentikan tinggal kata start diganti dengan "stop".

2. Buka SQLServer Configuration Manager, dan Aktifkan protocol TCP/IP untuk SQL Server. Pada jendela sebelah kiri, klik tanda + pada Protocols for Instance Contohnya untuk instance SQLEXPRESS. maka akan terlihat beberapa protocol untuk instance tersebut dengan status disable, termasuk status protocol TCP/IP disabled.

klik kanan pada TCP/IP kemudian klik Enable untuk mengaktifkan protocol TCP/IP. akan muncul pop up peringatan bahwa kita harus me-restart service SQL Server.jika kita mengaktifkan protocol TCP/IP kita juga dapat memilih IP yang digunakan untuk sambungan dengan jaringan.

2b. Restart service SQL Server dengan cara klik/pilih SQL Server Services pada jendela sebelah kiri, klik/pilih SQL Server (SQLEXPRESS) pada windows sebelah kanan, -> klik Restart. Service SQL Server akan restart.

Seharusnya hingga tahap ini anda computer lain (client) bias mengakses instance database pada computer (server). Selamat mencoba

*catatan : jangan lupa firewall di off. kecuali anda mau repot sedikit untuk melakukan exception pada firewall khusus untuk mengizinkan sqlserver ini bisa diakses oleh computer lain.

Troubleshooting :
1. Sql Browser tidak dapat di start

Memindahkan Aplikasi ke SD CARD Android 2.2 +

2011-07-23T21:46:00.000-07:00

Untuk memindahkan aplikasi android yang sebelumnya hanya bisa di simpan pada memori internal bisa anda lakukan sekarang. Tujuannya agar menghemat memori internal Smartphone Android anda. Berikut akan saya jelaskan langkah-langkahnya, dan tentu saja cara ini telah saya terapkan pada HP Android saya. Memang tidak sepenuhnya aplikasi android yang telah dipindahkan dari memori internal semuanya bisa dipindahkan, tetapi cara ini cukup ampuh untuk bisa menghemat memori internal anda. Untuk percobaan ini saya menggunakan HP Android Samsung Galaxy Mini S5570, dan Sistem OPerasi WIndows.
Berikut Langkah-langkahnya :
(Untuk langkah 1-4 dibutuhkan akses internet)
1. Download File SDK Android di Android.com

2. Aplikasi SDK Android membutuhkan file JDK 1.6 silahkan download terlebih dahulu sebelum menjalankannya

3. Install APlikasi SDK ANdroid di Laptop/PC Anda, dan jalankan SDK Manager.exe.
pastikan akses internet tersedia, tunggu sebentar karena SDK Manager akan melakukan sinkronisasi terhadap komponen-komponen yg bisa anda download nantinya.

4. Saat sinkronisasi komponen telah selesai, silahkan download komponen seperti dibawah ini :

tunggu sampai instalasi selesai.

5. untuk langkah ini akses internet tidak dibutuhkan lagi. sekarang persiapkan kabel usb anda dan hubungkan HP dengan laptop/pc anda, pastikan driver untuk HP Anda sudah terinstall di Laptop/PC, anda bisa menggunakan cd bawaan dari HP Anda.
HP TIDAK PERLU DIMATIKAN...

6. Sekarang Masuk ke command prompt (run--cmd) dan arahkan ke posisi instalasi SDK Android anda di folder "platform-tools".

pastikan hp anda terhubung dengan pC/laptop, dan untuk melakukan pengecekan ketikkan perintah : adb devices

jika hp sudah terhubung akan ada merk hp anda misalnya s5570...

sekarang saatnya mengeset agar aplikasi anda bisa dipindahkan ke sdcard, dengan cara mengetikkan "adb shell pm setInstallLocation 2" perintah ini case sensitive..

Dalam kondisi ini default instalasi akan bisa dipindahkan ke SD Card. silahkan anda lihat di "Setting--Application--Manage Application" maka tombol "Move to SD Card" akan aktif, sehingga aplikasi akan bisa dipindahkan ke SD Card.

7. Untuk mengembalikan ke default instalasi ke memori internal silahkan ketikkan perintah "adb shell pm setInstallLocation 0"

8. Selamat Mencoba... Lumayan Aplikasi kaya Facebook bisa dipindahkan ke SDCard, jadi bisa menghemat Memori internal kita.. Trims...

Cara melakukan Upgrade/flash Samsung Galaxy 2.2.1 froyo ke 2.3.4 Gingerbeard (Versi Eropa)

2011-07-19T13:59:00.000-07:00

Kabar gembira bagi teman-teman yang ingin mengupgrade OS Android Froyo ke Gingerbeard 2.3.4, karena secara resmi firmware Gingerbeard telah dikeluarkan walaupun untuk versi Asia belum tersedia. Tetapi, perbedaannya hanya pada segi bahasa saja, untuk versi Eropa tidak tersedia pilihan setting ke Bahasa Indonesia serta Asia lainnya.

Beberapa kelebihan Gingerbeard dibanding froyo (menurut pengalaman saya) :
1.Proses booting lebih cepat , terutama dari segi pembacaan memori sd card di awal boot
2.Peningkatan performa dari input text
3.Manajemen memori internal yang lebih baik, menurut pengalaman space di memori internal lebih besar setelah diupgrade (dengan kondisi jumlah aplikasi yg Terinstall sama dgn OS Froyo sebelumnya )
4.Terdapat aplikasi bawaan (Download, Youtube, dan tambahan menu di Setting untuk manajemen aplikasi dll )
5.Selebihnya silahkan tambahkan sendiri setelah mencoba..

Persiapan yang dibutuhkan :
• PC / Laptop
• Kabel Data USB
• ODIN Multidownloader V. 4.38.exe (Download di Samfirmware.com daftar dulu)
• Software Firmware 2.3.4 (127 Mb) (Download di Samfirmware.com daftar dulu gratis)
• Jangan lupa download file TASS V.1.0 di samfirmware.com sesuaikan.
• Driver HP Samsung (Sesuaikan dengan tipe HP nya) bisa di download di Samfirmware.com atau pakai Kies (CD Bawaan HP, didalamnya juga sudah tersedia drivernya)
• Backup Aplikasi Yg terinstall ke SD Card, Yang bagus pake Antivirus Pro, atau Astro Gratisan cari di market. Backup disini artinya mengembalikan aplikasi yg terinstall menjadi ekstensi *.apk saja. Artinya hanya mengubah menjadi master file saja supaya nanti bisa diinstall kembali tanpa perlu mendownload ulang.
• Keberanian ( Ini yg utama, karena resiko seperti yang saya lihat dari beberapa sumber bisa menyebabkan HP Brick atau mati. Tapi jangan takut, karena saya juga baru memiliki HP +- 4 bulan dan minim pengetahuan mengenai Android sudah berhasil melakukannya 2 kali, asal petunjuknya diikuti dengan benar)

Langkah Flashing :
1. Pastikan baterei HP diatas 50%, untuk jaga-jaga saja jangan sampai di waktu flashing HP Mati/ngedrop inilah kemungkinan besar yang membuat HP bisa mati.
2. Matikan HP, lalu masuk ke menu downloader HP ( Tekan dan tahan bersamaan ( volume down dan Tombol tengah) dilanjutkan dengan menekan tombol power)
Akan muncul gambar android dan tulisan dibawahnya “downloading”

3. Jalankan Odin Multidownloader.exe
4. Colok ke PC/laptop via USB Kabel,. Pastikan bahwa driver terinstall dan HP sudah terbaca dengan benar di PC/laptop. (lihat di device manager kalau sudah ada tipe hp anda di bagian modem berarti sudah ok) dan di aplikasi Odin ada isian tanda kuning di Com Port Mapping.
5. Siapkan 5 file firmwarenya ke ODIN:
a. Tass V.1.0 masukkan di Select OPS
b. APBOOT_S5570XXKPI_CL260130_REV02_user_low_true.tar.md5 select di BOOT
c. CODE_S5570XXKPI_CL260130_REV02_user_low_true.tar select di PDA
d. MODEM_S5570XXKPI_CL260130_REV02.tar di PHONE
e. CSC_.... di Select CSC
f. Yang lain tdk usah diatur biarkan default. EFS dan One Package (DIKOSONGKAN / NONE)
Pastikan di bagian “message” kelima file berstatus OK. Dan HP sudah di added/terbaca.

6. Jika sudah klik start maka pada kolom sebelah kiri di atas Com Port Mapping akan berjalan waktu downloadnya dan loading berwarna biru. Tunggu kurang lebih 10-15 menit. Sampai ada tulisan OK. (“Selama proses berlangsung HP akan nyala dan diakhir akan merestart sendiri dan bahasa di HP bukan bahasa Indonesia atau English”)
7. Finishing. Jika sudah OK, maka cabut HP,. Lalu rubah bahasa aneh itu ke bahasa English. Masuk ke menu setting (ingat iconnya saja), dan pilih Locale n Text (icon A) pilih bahasa english di menu pertama. Selesai..
Selamat Mencoba.

2009-04-02T19:46:00.000-07:00

JFreeChart adalah sebuah libray tambahan yang berguna untuk membantu kita dalam
membuat chart(bar,pie,timeseries,dll) pada program java kita, bersifat opensource, fitur2x yang lengkap untuk
membuat berbagai macam chart. Pokoknya JFreeChart merupakan library chart yang lengkap dan powerfull.

Berikut langkah-langkah yang dibutuhkan untuk membuat chart di java dgn JFreeChart :
1. download JFreeChart dr internet versi yg ada saat ini => jfreechart-1.0.5.zip(versi tar jg ada) terserah pilih mana.
2. ekstrak file tersebut. buka folder hasil ekstraknya, n terdapat beberapa folder di dalamnya spt:(ant,experimental,checksytle,gjdoc,lib,source,swt,test,dan file demo.jar)
klo mau lihat contoh2x chart yg bisa dibuat dgn JFreeChart buka file "demo.jar" click aja 2x.
3. file2x yang anda butuhkan (file2x .jar) agar bisa menggunakan JFreeChart ada di folder lib/(file.jar).
4. copykan semua file tersebut ke c:j2sdk1.4\jre\lib\ext\[file2x JFreeChart yg dicopy].
5. selanjutnya jangan lupa untuk mengarahkan/ mengeset ClassPath caranya :

asumsi : anda belum pernah menggunakan library ke 3(belum pernah setting CLASSPATH sebelumnya di komp.)
penting: untuk lebih aman, tambahin aja di variable value nya alamat semua file2x jar yg ada di folder ext
caranya sama aja kaya nambahin file jfreechart-1.0.5.jar dan jcommon-1.0.9.jar
n tiap alamat diakhiri dgn ";"
c. ok
6. anda sekarang sudah bisa menggunakan library2x dan kelas2x yang ada di jfreechart.

Sekilas Kelebihan Bahasa Pemrograman Java

2009-04-02T19:43:00.000-07:00

Apakah Java itu?

“Java adalah suatu teknologi di dunia software komputer. Selain merupakan suatu bahasa pemrograman, Java juga merupakan suatu platform.”
Penulis secara ringkas telah menjawab pertanyaan tersebut dalam kalimat tersebut, dan berikut ini penulis akan menjelaskan lebih lanjut:
“Java merupakan teknologi di mana teknologi tersebut mencakup Java sebagai bahasa pemrograman yang memiliki sintaks dan aturan pemrograman tersendiri, juga mencakup Java sebagai platform yaitu di mana teknologi ini memiliki virtual machine dan library yang diperlukan untuk menulis dan menjalankan program yang ditulis dengan bahasa pemrograman java”.

Asal muasal Java

Java diciptakan oleh suatu tim yang dipimpin oleh Patrick Naughton dan James Gosling dalam suatu proyek dari Sun Microsystem yang memiliki kode Green dengan tujuan untuk menghasilkan bahasa komputer sederhana yang dapat dijalankan di peralatan sederhana dengan tidak terikat pada arsitektur tertentu.
Mula-mula James Gosling menyebut bahasa pemrograman yang dihasilkan dengan OAK tetapi karena OAK sendiri merupakan nama dari bahasa pemrograman komputer yang sudah ada maka kemudian Sun mengubahnya menjadi Java.
Akhirnya setelah melalui beberapa transformasi dan proses, Sun akhirnya meluncurkan browser dari Java yang disebut Hot Java yang mampu menjalankan applet. Setelah itu teknologi Java diadopsi oleh Netscape yang memungkinkan program Java dijalankan di browser Netscape sejak January 1996 yang kemudian diikuti oleh Internet Explorer. Karena keunikan dan kelebihannya, teknologi Java mulai menarik banyak vendor terkemuka seperti IBM, Symantec, Inprise, dll.
Akhirnya Sun merilis versi awal Java secara resmi pada awal 1996 yang kemudian terus berkembang hingga muncul JDK 1.1 kemudian JDK 1.2 yang menghasilkan banyak peningkatan dan perbaikan sehingga mulai versi ini Java disebut Java2. Perubahan yang utama adalah adanya Swing yang merupakan teknologi GUI (Graphical User Interface) yang mampu menghasilkan aplikasi window yang benar-benar portabel.
Dan pada tahun-tahun berikutnya (1998-1999) lahirlah teknologi J2EE (Java 2 Enterprise Edition) yang berbasis J2SE yang diawali dengan servlet dan EJB kemudian diikuti JSP. Kelebihan Java di lingkungan network dan terdistribusi serta kemampuan multithreading mengakibatkan Java menjadi cepat populer di lingkungan server side.
Terakhir teknologi Java melahirkan J2ME (Java 2 Micro Edition) yang sudah diadopsi oleh Nokia, Siemens, SonyEricsson, Motorola, Samsung untuk menghasilkan aplikasi mobile baik games maupun software bisnis dan berbagai jenis software lain yang dapat dijalankan di peralatan mobile seperti ponsel.

Kelebihan Java
Mengapa Java sering dibicarakan dan memiliki daya tarik bagi para programmer? Karena Java merupakan suatu teknologi yang unik dan revolusioner dan merupakan teknologi pertama di dunia software yang memiliki semboyan “write once, run anywhere”. Semboyan tersebut telah terbukti karena banyak program Java dapat dijalankan di berbagai platform Sistem Operasi, seperti Linux, Windows maupun Unix.
Java telah mengatasi masalah portabilitas yang sering menjadi kendala dan hambatan dalam pembuatan suatu aplikasi software. Mengapa? Karena software developer harus mengeluarkan banyak tenaga, pikiran dan waktu untuk menghasilkan aplikasi yang dapat berjalan di operating system atau platform lain.
Java dapat mengatasi kendala tersebut karena program Java dapat dijalankan secara langsung tanpa banyak perubahan berarti di sistem operasi atau platform lain.
Java juga didesain untuk menghasilkan program dengan seminimal mungkin bug karena kemampuan sebagai berikut :
• Java didesain untuk menghilangkan alokasi memori dan dealokasi memori secara manual. Java memiliki garbage collection otomatis yang mencegah adanya memory leak. Memory leak adalah masalah yang sering dihadapi programmer c dan c++ dimana memori yang digunakan untuk objek atau variabel yang sudah tidak digunakan tidak didealokasikan sehingga memungkinkan adanya kehabisan memori karena proses alokasi maupun dealokasi yang tidak diatur dengan baik.
• Java memiliki array yang tidak memerlukan pointer sehingga memudahkan para programmer.
• Java menghilangkan banyak kebingungan terjadi apabila terjadi proses assignment(pemberian nilai) pada statemen konditional seperti berikut:
if (varnya=5)
Kode di atas menyebabkan program Java tidak dapat dikompilasi karena Java membedakan tanda = yang digunakan untuk pemberian nilai dan untuk pengecekan kondisi true atau false yang harus menggunakan tanda = ganda (==).
• Java menghilangkan multiple inheritance pada c++ dan menggunakan interface yang memiliki kemampuan sama tetapi lebih sederhana.

Karakteristik Java

Secara singkat, karakteristik Java adalah :
• Sederhana
Java tidak memiliki sintaks aneh tetapi banyak menggunakan sintaks c++ yang sudah banyak dikenal sehingga java tidak menyulitkan bagi para programmer. Bahkan java memberikan banyak peningkatan dan kemudahan dibanding c++.
• berorientasi objek
Java merupakan pemrograman berorientasi objek yang murni. Dalam pemrograman Java semua adalah objek, terkecuali tipe data primitif.
• dapat didistribusikan dengan mudah
Sifat terdistribusi dari Java sangat tampak sebagai applet dan library yang mampu bekerja dalam jaringan dan bekerja dengan objek terdistribusi (RMI) dengan sangat baik. Saat ini Java juga memiliki kemampuan untuk server side processing yaitu teknologi Java Servlet dan Java Server Pages.
• aman
Aman karena program Java memiliki library security serta policy yang membatasi akses applet di komputer client.
• diinterpretasi oleh interpreter
Java memerlukan virtual machine yang bertindak sebagai interpreter yang menterjemahkan bytecode (file class) menjadi bahasa mesin yang dimengerti oleh komputer host.
• portabel
Portabel karena Java dapat dijalankan di berbagai platform tanpa perubahan kode sama sekali.
• multithreading
Java memiliki kemampuan untuk menangani dan menjalankanbanyak thread sekaligus.
• dinamik
Java merupakan teknologi yang terus berkembang, dan hal ini tampak nyata sekali dengan library yang terus ditingkatkan kemampuannya dan kelengkapannya. Bahkan Java saat ini telah menjadi teknologi handal untuk aplikasi mobile dengan adanya Java 2 Micro Edition.
• netral terhadap arsitektur hardware
Java dapat dijalankan dengan baik pada komputer yang memiliki arsitektur berbeda-beda.
• robust
Java merupakan teknologi yang mampu menolong programmer untuk menghasilkan program secara cepat dan handal karena Java mencegah adanya memory leaking, meniadakan pointer(yang merupakan keharusan pada programmer c dan c++) serta mencegah berbagai error yang mungkin terjadi dengan adanya berbagai proses pengecekan awal pada kompilasi.

Using AJAX in PRADO Application with CallBack Event

2009-04-02T18:58:00.000-07:00

Requirements : You have already know about prado v3.x basics, and Connection to Postgre SQL database using TActiveRecord.
This time I will show you how easy using Ajax in Prado for create a simple web application with two combo box that have related each other, and both are connected to database for binding the items. When I choose the item from the first combo box , the second combo box will load items that have a relation with item that I have choosed from the first combo box. In desktop application there was no problem for doing that, but in web application you can’t directly do that, because normally in web if you want to access to the database you must send some parameter and then the page and item that you have choosed from the first combo box will automatically refreshed.
The First Question is : “how can I do that things, without refreshing the page and the selected item still appear at the first combo box”? The answer is , You must using Ajax.
The Second Question Appear: “I don’t know anything about Ajax programming, Can I do that using Prado ?” The answer is , Of course,You don’t have to know about Ajax programming, the only thing you know is Prado already support Ajax, and you can easily using Ajax with Prado.
This is the example program :
We have 2 table for example, each table will represent the combo box at the presentation logic. Then I’ll create database in postgre sql 8.x named “dbblog”

This is the sample data :

Of course we must already prepare the prado project skeleton :

This is the code for Application.XML . there are two important setting here the “ActiveControls” and “Database Connection to PostgreSQL with TActiveRecord”

Next, we must create two class that represent 2 table (tbl_prov.php & tbl_subprov.php) which inherited From TActiveRecord Class. Place it below database folder.
tbl_prov.php

tbl_subprov.php

Now we must create 2 files below pages folder : Home.page (presentation) and Home.php (process)
Home.page

Home.php

That’s all,.. now you can try to access your application. Then you can select any item in the first combo box, and the second combo box will automatically load items related to it. And of course without refreshing the page.. it’s so easy using Ajax with Prado Framework..And the most important, there are no different logic between web application with Prado Framework and desktop application (event driven) you can see it at home.php file and compare it with logic when you create a same applicaton with vb or other even driven desktop application.

6 Way To increase Earnings

2009-03-05T02:15:00.001-08:00

Welcome to our first-ever guest blog post on Inside AdSense. We're
thrilled to have none other than Blogging Evangelist himself, Darren
Rowse, to share his expert tips on AdSense optimisation. Darren first
discovered blogging in 2002, and initially thought he'd turn it into a
hobby to supplement his full-time job. These days, Darren runs a
handful of successful blogs, his most popular being Digital Photography
School, and has co-authored a book. He also posts regular tips and
advice on ProBlogger.net, a respected and successful resource for
bloggers around the world.We recently caught up with Darren at his home
office in Melbourne Australia, and asked him about his experience with
Google AdSense.October 4, 2003 is a date I'll never forget - that was a
day that my life changed. It was the day that I discovered AdSense and
added it to my very first blog. I added that first advertisement to my
blog on a whim, with what I thought was the lofty dream that I might be
able to pay for my blogs hosting costs. Over 5 years later, those
little text ads have paid my mortgage, fed my family, and enabled me to
move my blogging from a hobby, to a part time job, to a full time job
and beyond.It's not been an 'overnight success' by any means but as
I've learned to use it, AdSense has been one of my highest online
income streams. My #1 Tip for Using AdSenseIf I had to narrow my advice
on using AdSense down to a single word it would be 'experiment'. Let me
explain. That day back in October of 2003 I had no idea on what I was
doing. The next day when I logged in to see how much I'd earned it was
barely enough to buy me a coffee. However, on that day I decided that
those few dollars in earnings showed potential and I determined within
myself to learn how best to use AdSense to grow that income. Almost
everything I've learned since that day has been through trial and
error. It has been a long process of testing and tracking results. You
see, while there are a few good home truths that seem to work on most
sites, every website that I've used AdSense on is different. Some
things work well on some sites, but it is rare to find something that
will work on every site. As a result I tend to experiment with my use
of AdSense in these six ways:
- Ad Position - Most AdSense publishers have seen the neat little heat
map that AdSense has produced to show where ads work best on websites.
In general it works fairly well and is a great place to start, but make
sure you experiment with new positions for ads and see what works best
for your site. Hint: Ads near (or even surrounded by) content have
worked the best. I've also found ads at the end of content perform
well. People get to the end of reading your article and then are
looking for something to do or click -- an ad positioned there can work
well.
- Numbers of Ads - More ads earn more than less ads... don't they?
Unfortunately it isn't always the case. Test different combinations and
numbers of ad units on your site. There's usually a 'tipping point'
where you hit a ceiling of how many ads your users will accept -- push
it too far and you could hurt reader engagement, traffic, and in the
long run your earnings. On the flip side of this, don't be afraid to
have more than one or two ads on a page, particularly if you have long
pages with lots of content.
- Ad Design - I can still see the first ads that I first used on my
blog back in 2003. I can still see them because they fried their
imprints into my retina -- they were so LOUD! I figured that the ads
would do best if people noticed them so I went for the most crazy color
scheme I could come up with. Over the years I began to experiment with
different combinations of ads and found that more subtle or blended ads
tended to work best for me. Having said that, you can sometimes blend
too much, to the point that the ads become invisible to your reader. So
test different colors and designs of ads to see which work best. Use
the ad rotating tool that AdSense offer publishers to rotate different
designs to work against ad blindness among regular readers.
- Ad Sizes - AdSense offers us a range of different ad sizes, so
experiment with them all to see which works best. Hint: Some might
think that the bigger the ad the better it performs. This is not always
true. For example, I found that the 'large rectangle' ad (336 x 280)
didn't work as well for me as the smaller 'medium rectangle' ad (300 x
250). It turns out that more advertisers (at least those in my niche)
prefer the medium rectangle ad as it's a more standard ad unit size
than the larger one. Again, the key is to experiment and see what works
best for your site and niche.
- Ad Formats - I've found that choosing image and text ads works better
than just choosing text ads, but that's not the only choice we get as
AdSense publishers. AdSense also allow us to run link units, AdSense
for search, etc. I've found that each of these different formats will
work differently from site to site. I've had blogs where the link unit
ads were the best performing units on the site while on other sites it
didn't really perform at all. You'll never know unless you test it!
- Which Content Converts? - One of the best advances that AdSense has
made in the last year has been the integration between it and Google
Analytics. To be honest I'm still digging into the metrics that this
opens up, but the insight that this gives has amazing potential to
increase earnings. By looking at this data you can see what type of
content is converting and what isn't. You can also see what type of
traffic is converting and what isn't. For example, I've found that
search engine referrals are converting better than traffic from social
media sites on one of my blogs. Knowing this is powerful as it tells
you what type of ads to serve to what types of traffic, what type of
promotion to put effort towards, and what type of content to write more
of.Test Track Test Track....There are books, blogs, articles, forums,
and other kinds of resources available to AdSense publishers to help
them learn how to use AdSense better. However, in my experience the
best way to learn is to 'do'. Put time aside to try new things and then
put more time aside to review what you learn. But don't leave it at
that. When you learn something -- test it against something else (do
some research on A/B split testing to learn how to do this). This
continual learning will help you to grow in your own expertise of
AdSense and increase your earnings.Posted by Darren Rowse - Blogging

Types and causes weakness of the Website

2009-03-02T00:57:00.000-08:00

Source : Syafii, M,. 2004. Panduan Membuat Aplikasi Database Dengan PHP5 Postgre-MySQL-Oracle.Penerbit Andi. Yogyakarta.

Deface
You may have often heard or saw a site that has content not suitable. Obvious example is a site-education institutions (ac.id) to the index page of the official website of the picture or logo has been changed. Incident, in the world of hacking, called deface. Deface is an attack technique with the image or change the content of the website for a particular purpose. In fact, there are many factors that cause all of that. According to the analysis of the author, these factors are:

1. Operating system
If you intend to buy the domain and hosting, make sure that the operating system is safe and reliable in use, such as for example a Unix operating system variants. Please note that almost all of the hosting center are using Redhat Linux.
2. Programming Error
Low awareness of the website you are easily exposed to deface. For example, the error in using the user management in MySQL, but the data show that the user is able to perform SQL delete, insert or drop. This is the common mistakes that seemed as a habit that can not be abandoned. If you compile a program that uses a web-based MySQL database then you should have a user that is able to select the command, if you are only a web show in the MySQL database server to the web. You can create new users that are only able to insert or delete command. Deface technique done with the action called SQL Injection.

Password Theft
Another thing is to be considered when creating web pages that have a user authentication system. You must create a program may be safe to include encryption. No password or data encryption so people can easily tap (Sniff) your data. Thus, the use of encryption is also very necessary.
Creating confusion in the Directory
Avoid making the directory easy to order and the name is known by other people. For example, almost all websites have a folder called images, include, or other similar folders. This of course should be anticipated so that if users try to access the way, we already have a preventive action.

Error in File Include

When you read a lot about PHP3 tutorial or an older version then to insert a file in the PHP file is to provide the Include ( "db.inc"). In fact, if the *. inc files are called directly from the browser the contents of the file will be displayed. This means that someone can see the contents of your original file. If you just paste the file does not contain the usual problems. However, if you paste the configuration file contains a database then this will be dangerous.
Permissions for the folder contents
Keep other people can not easily find out each folder that you created in the order in the structure of the website. People can do it directly by typing the name of the folder. For example, if someone typing directly in the addres bar:

http://localhost/happy-holidays/images/

you can prevent problem like this by changing the configuration for httpd.conf in the folder under Apache, with the command to change or delete Options Indexes MultiViews tags below Directory. Another way that is easier to add in the index.php file in every folder that does not have the file index.php. So if someone tries to access directly the contents of a folder in the web then index.php file will be automatically executed, and the contents of the folder we will not appear as the image above.

How can I make my blog load faster?

2009-02-26T01:13:00.001-08:00

Link Source : help.blogger.com
The speed at which your blog loads is critical to attracting more readers to your blog. If your blog takes a long time to load, many readers may leave your blog before they have the chance to read it. Here are a few tips and tricks that will help your blog load faster and attract more users:
Posts

Your blog's load time can be affected by the number of posts you display on your main page. You can easily edit the number of posts displayed of the main page from the Settings | Formatting tab. You can then select the number of posts you want to display on the main page. We recommend displaying 10 or fewer posts on the main page.
Third Party JavaScript and Links

For optimal blog load speed, we recommend using Google/Blogger widgets, JavaScipt and links. However, if you need to use third party JavaScipt and links, your blog will load much faster if you put all JavaScript at the bottom of your blog. If you have third party JavaScript and links in your sidebar, put them in at the bottom of the sidebar.
Images and Media

The more images, videos and other multi-media you have on your blog the longer it will take to load. However, images and other multimedia are important to attracting users to your blog, so it is important to optimize the load speed of your images and media. Here are a few tips to increase the load speed of your media:

* Decrease the size of your images or use thumbnails that link to the full-size image.
* If you use third party images, consider uploading them to Picasa Web Albums via the Blogger post editor.
* If you have a large number of images to display, you can upload all your images (from a vacation or event) to a Picasa Web Album and link to the album in your post or sidebar.

Other suggestions

* If you've added any custom CSS to your blog, make sure you put it at the top of the page.
* The most important content of your blog that catches readers attention should load the quickest. To help you identify which items are taking the longest to load you can use Stopwatch. To use Stopwatch, enter your blog's URL into the text box and click "Start StopWatch". Stopwatch will then open your blog in a frame and will record the time it takes for everything on your blog to load, including images, videos, widgets, etc. Take note of the items that take the longest to load and modify them appropriately using our suggestions.

What is SEO?

One of the many indications of a successful website is traffic. Traffic shows that tune by website visitors. One effective way to bring visitors to the website is through search engine. Usually the visitor will find the website through search engines by using keywords or keyword.

Hope the website owner of course appear in the top search results on search engines because the tendency will of course visitors to click on results - results that appear top.

The question then is how our website can appear on the search results for search engine keywords - keywords that are relevant to our website content? Further how we can so that the website appears on top in order to attract more visitors?

SEO solution
SEO is the process of a web page that can be read better by search engines which are crawler (Google, Yahoo, MSN, etc.). SEO process can involve a web page itself, but does not also involve the possibility that other website.

Not all of the website be properly by search engines. Website that use the full flash at all at this time can not be read properly by search engines, while the website will meet the W3C standard can be read perfectly by search engines. Search engines will also be difficult to read the web using JavaScript and web navigation with the frame.

Many factors that determine success in SEO. In addition, the method for search engines to index the search results are often changed. Therefore, the SEO can be said is very dynamic because the method changed from time to time, and also the SEO can not guarantee whether your website will appear in the top of the search index or not. Please see the article - an article about SEO in this website and start generate traffic from search engines. Cheers!

Variable in PHP

2009-02-25T00:02:00.001-08:00

PHP recognize the existence of variables and operators, as other programming languages. Required to declare the variable and the value of a. The operator is required to perform mathematical calculations, giving values to variables in a particular, and to compare the value of two variables.

What are the variables?
Variables used to store data temporarily and the value can change each time the program is run. Data stored in the variable will be lost after the program finished executable.

PHP Variable and Value Types
PHP variables start with 'Variable name can be a combination of alphabet letters, numbers with a maximum length of 32 characters. Variable names are case-sensitive. Variable name can only be beginning with the letter or underscore, then the characters can be letters, numbers, and underscores. To be able to use variables, need to be two things:

Declaration
Declaration of variables is introduced to the program. In writing the PHP script, often combined with a declaration initialization. Example:

$ value, $ day.

Initialisation
Variable initialization is to provide a value for the first time to a variable. Example: Value = $ 50, $ = NamaHari Monday.

PHP variables have some type of value that is:

Integer (Numbers rounded)
The integer can be written in the form of:
Decimal number, for example: $ a = 1234;
Negative decimal number, for example: $ a = -123;
Hexadecimal number, for example: $ a = 0x1A with the same number of decimal 26;
Octal numbers, for example: $ a = 0123; with the same number of decimal 83
Floating Point
Floating Point Numbers can be declared using the following syntax:
$ a = 1234;
$ b = 1.2e3;
A maximum value of the Floating Point ~ 1.8e308 is reached with the accuracy 14 decimal digits.
String
Syntax string variables can be written in 3 ways, namely: Using single quotes ( ') example:
$ str = 'Hello Nano';
Using double quotes ( ") example:
$ str = "Hallo";
Using sign heredoc (<<<)

About HTML

2009-02-24T16:46:00.000-08:00

Introduction to HTML

HTML (hypertext markup language) is a language that uses a simple command in the standard ASCII text document to provide a visual display that is integrated. HTML consists of simple commands that describe how the structure of the document, but does not do formatting. The browser will display the HTML formatting and display HTML, so adjust according to the visitor's computer screen.

HTML tag using the form <...> that a web browser how to display page elements such as text or graphics. HTML code is located between the container tags with <..tag_name> beginning and end with <..> with '/'.

HTML tags have three main units, the HTML, HEAD and BODY. HTML tags represent a function of the HTML document, tags HEAD function provides information about the document, and determine how the BODY tag contents of a document displayed by the browser.

HTML example script:
Views in the Browser:
In the BODY tag you can write a script to set the HTML view as a background color, font size, font type, font color, links to other documents, add images and so forth.
If the script with the HTML course we can create a web page that is good, and why you need to add a PHP script? PHP create HTML web pages to be dynamic. HTML combined with the PHP script will generate a dynamic web views, beautiful, and interactive. PHP and HTML will be mutual cooperation. PHP can generate HTML, and HTML can forward the information to PHP.

Take an MP3 File and Delete the Words to Create Karaoke

2009-02-23T22:31:00.000-08:00

Do you need music for your Karaoke party, or just want to sing along to your favorite song without those pesky singers getting in your way? Here's a few ways to get a song without any vocals.

Find Instrumental Versions
1. Go to any search engine, like Google, and type the name of the song, the artist, or both. Put the song name in quotes to narrow the search.
2. Add the word "instrumental" or "karaoke" to the search.
3. Add the word "MP3" to your search if needed; it may expand/narrow the range.
4. Make sure the song you're downloading is legal and virus free.

Automatically Removing Vocals with Wavosaur

1. Get the audio editing program "Wavosaur"
2. Open up the song
3. Go to process>effects>vocal remover
4. Does exactly what is outlined underneath.
5. Save it as .wav

Removing Vocals Yourself
1. Get the regular MP3/OGG/WAV of the song you want. Make sure it's legal, in stereo and of the highest possible quality (at least 128kfor MP3, 192k is better)
2. Obtain a copy of the free audio editor Audacity. Other programs are available, but they usually cost and this will do fine. Install the program, read the help files and familiarize yourself with the interface, as the individual instructions are beyond the scope of this article.
* Download the LAME MP3 codec if you want to export your project to MP3, and install it per the instructions for Audacity.
3. Import the MP3 to a new project in Audacity.
4. Open the track menu (click the arrow next to the track title), and choose “Split Stereo Track.”
5. Select the lower track (the right channel) by clicking it in the area around the mute/solo buttons.
6. cut the bass out of the second channel from around 100hz and below (adjust cut frequency to keep bass guitar, kick drum and other bass instruments that are below voice frequencies)
7. Choose “Invert” from the Effects menu.
8. Using the track menus, change each track to “Mono.”
9. Listen to your track, and if it sounds alright to you, go ahead and export it to MP3 or WAV, depending on what you need.

Tips
* The better the original song, the better your vocal-less version will sound.
* Make sure your MP3 is in stereo, or this will not work.
* Avoid "Vocal Cut" and other similar features in audio programs. They usually do this same thing, or attempt worse procedures, and never sound as good as doing it manually.
* This process works by "cancelling out" all the information in the exact center of a stereo recording, through Phase Inversion. This is usually where vocals reside, but, the center pan will also generally contain the drum/bass tracks on most songs, and you'll lose most of those as well.
* Don't be surprised if "echos" of the vocals remain. Unless the vocal is perfectly clean, and centered on the track, any reverb or flanger effects will most likely stay present. This also applies to backing vocals.
* If this process makes the song unlistenable, there are ways to fine-tune the procedure. However, the discussion on audio theory and technical details is beyond this article. Searching the Internet will possibly find you some more help, if you need it.
* To check if your song can become vocal-less, on your MP3 player or whatever multimedia player you use put on the song you wish to turn into a karaoke, as the song plays unplug your headphones and put them slightly in so you can still hear the music and lightly push in the headphones until you can't hear the vocalist and once your on the stage you can't hear much of the vocalist hold in where the position of the earphones are in (Caution: this can damage your earphones so be sure you are using old ones) if during the process you can still hear the vocalist clearly, then it's a clear answer that you cannot turn the song into a karaoke but if you can still hear the echoes of the vocalist then it's okay for the song to become karaoke. This is useful because you can determine if the song you want as a karaoke can be vocal-less.
* For more luck with this procedure, try following these steps on tracks from a band that you know was self-recorded, or did not seek the use of a professional for recording.

Things You'll Need
* Audacity, the free audio editor (or similar)
* A copy (MP3/OGG/WAV) of the song you want
* Moderate technical knowledge
* Patience

7 Cool Software Easter Eggs To Discover

2009-02-23T17:49:00.000-08:00

Easter eggs

In the virtual world, it’s little lines of code inserted into the main programs that show up through a combination of key strokes or commands. Often it is a prank or just a bit of playful ego on the part of the programmer that ‘hatches the egg’ but for us common folks the discovery is unexpected fun.

So here’s a look at the basket of some popular software Easter eggs found in some common Windows applications…

1. Solitaire is easy (only in XP)
If you are finding it difficult to win in Solitaire, just press Alt + Shift + 2. Presto! The game ends and you win.

2.Foul play at FreeCell (only in XP)
Start a new FreeCell game. Hold down Ctrl + Shift + F10 during play. A dialog box appears asking you to Abort, Retry or Ignore. Select Abort and then move any card anywhere to win the game.

3.Window speaks proper (only in XP)
Go to Control Panel, open up the Speech properties applet and in the Preview field type ‘Crotch’ (without the quote). The voice preview says “Crow’s nest” instead.

4.Windows Welcome Music (only in XP)
An ambient music track you might not have heard before. Navigate to C:WindowsSystem32. We are looking for a folder named ‘oobe’. This folder has a subfolder named ‘images’. In ‘images’ click on the sound file called ‘title.wma’ to hear the soothing track – Windows welcome music.

5.Firefox’s comeback
This was supposedly a rejoinder to the Internet Explorer 5’s own joke that the Mozilla browser caused system crashes. To see Firefox’s reply type ‘about:Mozilla’ (without the quotes) in the address bar and hit it.

6.Firefox and the kitchen sink
In the address bar type in ‘about kitchensink’ (without the quote but with a space). Look at the interesting graphic that opens up.

7.Running Firefox within another Firefox
There doesn’t seem to be any apparent use for this but if you type in chrome://browser/content/browser.xul in the address bar, it will open up another Firefox instance but within the first browser.

SEO Tips-1

2009-02-23T17:16:00.000-08:00

Is not SEO (search engine optimization) is not liked by Google and other search engines. In the previous post I wrote:

The blog title is the first thing seen by google index. Therefore, make the title true title dg posts (articles) and content (content) a post it is very important to get a good position when people search for specific articles via the search engines (search engines) such as google, yahoo and msn.

Then, the blog title that is not how it SEO?

Following list of titles that are not SEO blog. Please added their own comments in the box if there is another:

* Welcome to My Blog or Welcome to My Blog
* Another Blog of Mine
* The Secret
* Campursari
* Etc.

Basically, the blog title that SEO is not a title that does not explain anything or no relevance with the actual blog. If you have a personal blog, should just write your name as the title.

Tips to make computer networks (LAN / Local Area Network)

2009-02-23T01:27:00.001-08:00

computer network? what network? we often hear, but we dont know what it is.
we can imagine like our bodies network (network cells). in our bodies, every device that is connected to each other,
function with each other to work together, although each has a function of levying their own.

a system of said computer network if there is a single computer model that serves all of the tasks
computing an organization has been replaced by a set of computers that many fragmentary but
each other in performing its duties.

other definition of a computer network is a collection of computers, printers and other equipment that
connected in one unit. Information and data moving through the cable-cable or without cable, so
allows network computer users can exchange documents and data, print on a printer
together and jointly use the hardware / software that is connected to the network.

Benefits of Network Computers:

* Resource Sharing, you can use existing resources together. Eg a user who
located 100 km away from the data, does not have difficulty in using this data, as though
data is located in close proximity to us. This often means that troubleshooting computer network distance.

* Reliability, with the computer network we will have a high reliability with the resources have
alternative supplies. For example, all files can be saved or copied to two, three or more computers that
connected to the network. So that when one engine was damaged, the copy machine in the other can be used.

* Save money. Computers have a small ratio of price / performance is better than the
a large computer. Mainframe computers have such great speed approximately ten times the speed
small computer / personal. However, the price Mainframe thousand times more expensive of computer time. Imparity
the ratio of price / performance and speed of this is to make the system designer to build a system that consists of
personal computers.

The steps:

To create a small computer network (LAN), there are some equipment and materials that we need such as:

* Cramping

* Lan Tester

* Cable UTP (Unshielded Twisted Pair) / coaxial (rarely used)

* RJ45 Connector / coaxial cable connector

* Switch hub * min-2 units PC (Personal Computer) with LAN Card, or NIC (Network Interface Card)

Then we define the order of UTP cable that we will use in accordance with its function. eg if we wanted
connect directly from PC-PC, we use the cross, if kia-connect switch to hub first, PCHUB,
then we use straight. if we want to connect 2 LAN HUB-HUB then we use the cross,
we can also use the STARIGHT if there is one hub uplink port.

for ease in remembering the order of the cable, we can use one of the ways that I use, namely
Straight -> if OBHC Cross -> HBOC.

Straight -> OBHC

O -> white orange - orange

B -> white green - blue

H -> blue white - green

C -> white chocolate - chocolate

Cross -> HBOC

H -> white green - green

B -> white orange - blue -

O -> white blue - orange

C -> white chocolate - chocolate

if you have another way please apply, I must be as above. then please each end
tested using lan tester. if the lamp lights according to the expected, then you have succeeded in
Cramping process. please lan card installed on your PC.

to set the IP so that we think about is how no group IP that is used on your LAN. usually for
local network using the IP group 172.17.XX, 192.168.XX 202.168.XX or 10.10.XX to the local network,
minimal set is:

IP address: 192.168.1.2 (example)

Subnet mask: 255.255.255.0 (example)
for the default gateway you can fill in if you want to connect your local network with external networks (both
local network or other internet). for the DNS server you will be content if you are connected to the internet. This DNS server
depending on the rules established by the provider, Telkom Speedy, etc..

if you have no IP set, you can check whether your computer can communicate with
other computers, that is the way to run the ping command in the command, such as

ping 192.168.1.3

(this command produce 4 times the response), to continue to provide the response we add the attribute-t (trace),
like

ping 192.168.1.3-t

No response was given 3 kinds:

1. reply from ....

your computer can communicate with the purpose of your computer.

2. request time out ....

network connectivity problems with the purpose of your computer.

3. destination unreachable ....

network connection to your computer problems.

Joomla Overview

2009-02-23T01:00:00.000-08:00

Joomla! is a content management system (CMS or CMS) is free and open (free opensource) is written using PHP and MySQL database for the internet or intranet. Joomla first released with version 1.0.0. Features Joomla! are caching system to improve performance, RSS, blogs, Polling, etc.. Joomla! use the GPL license.

Origin of the word Joomla itself comes from the Swahili word that means "togetherness."

Joomla basic principles
In general and explicit, Joomla! consist of 3 basic elements, namely the web server (webserver), PHP scripts and MySQL database. Assumed that the web server connected to the Internet / intranet that serves as a service provider site. PHP script consists of program code in the PHP language and database is the place where the content. Joomla using Apache as the web server and MySQL for basisdatanya.

First, the user requesting access to a page with Joomla execute the URL in a web browser which is then connected to the web server. This request in the more technical term known as the query string in addition there is a URL parameter also contains the content (section, category, article ID and others). Based on these parameters, the system script to contact with the Joomla database and retrieve content that is based on its parameters. Finally, the content and the templates (templates) coupled with the return and as html pages, images, css and javascript.

Package Joomla! consists of several separate parts and termodul a very flexible, can be easily developed and integrated. For example "plugins" that allow the author WikiBot in Joomla using the "Wikitags" in the article that function automatically create dynamic links to Wikipedia articles when displayed. There are more available in 1700 "plugins" which officially delegated by the http://extensions.joomla.org/ OpenSourceMatters available at this time and officially moved to http://joomlacode.org with the support of a more complete server.

About ActionScript 3.0

2009-02-23T00:39:00.000-08:00

What is ActionScript?

ActionScript is a language program for the Flash Player. Have the ability as animation, data handling, and more support in the flash-based application. ActionScript executed by ActionScript Virtual Machine (AVM), which is part of Flash Player. In the ActionScript code will be compile into bytecode by the compiler such as the Flex SDK and Flex Data Services. This bytecode will be placed on the SWF file, and will be executed by Flash Player. Other features of ActionScript 3.0 is a robust (fast) and is the object oriented programming.

Benefits from ActionScript 3.0
ActionScript 3.0 has the ability to recognize the previous version of the script. Designed to facilitate large-scale application development and complex use of a large set of data with object-oriented approach, and are reusable (code that can be used again). ActionScript 3.0 will be executed over ten times faster than the previous version of ActionScript.
Compatibility With Previous Versions
All versions of ActionScript can be identified using the Flash Player 9 and the latest. Here are some statements regarding the compatibility of ActionScript:
1. A SWF file can not combine ActionScript 1.0 or ActionScript 2.0 to 3.0.
2. ActionScript 3.0 can be read (load) SWF files written using ActionScript 1.0 or 2.0, but can not access the variables and functions of the SWF file.
3. SWF files written using ActionScript 1.0 / 2.0 can not read (load) SWF files written using ActionScript 3.0. This means that the SWF file generated by Flash 8 or Flex Builder 1.5 can not read SWF files written using ActionScript 3.0.
4. In general, SWF files written using version 1.0 and 2.0 must be changed if used together with SWF files written with ActionScript 3.0.
The diagram below summarizes some of the limitations of previous versions of Flash Player.

Class OOP versus Function

2009-02-23T00:20:00.000-08:00

In the previous tutorial oop PHP, we have learned about the 5 key term in oop. But before we discuss further fifth term, we will first learn the concept of oop alias Object Oriented Programming. This concept is certainly valid for the general good of PHP and other programming such as Java support oop.

Remember this. Actual oop is a way of thinking in creating the program.

In fact in many cases, our program will not differ greatly with the methods that may be structured for this we know. But the important thing is to think how to make everything as an object. Remember this keyword: Think of an object. The more simple, when we create a program, then we will create a variety of classes that we will often use the class and we will make into an object that you can develop later.

Usually books or tutorial will be using examples of objects such as a cat, a house or car. Because the explanation that describes the process of program-based oop similar to the way we think everyday. If not, please believe you buy or read books about oop.

But I never felt that the explanation itself directly with the real examples in the real world has become an example of programming in the abstract. Because we may not make a cat or a house or car with PHP? Therefore I will give a slightly different explanation. I will not start from the example of a real example the abstract, but from the way some thought in making program. Next we see a new process of thinking oop with comparisons to the day-to-day life of yesteryear.

Hopefully more clearly.

Ok, to make it easier to imagine how to make a difference in a normal program and oop, I will submit some of the comparison between the way of thinking in the programming. Ready?

At the beginning of our career, we will generally make a program without function. For example we will create a calculator program. In this example we will focus on making the appearance.

Imagine a calculator. We definitely need to make the future look like a calculator that is not it? Where there are a few key numbers and mathematical operations, and the screen will display any of us in the press that button, and others. Furthermore, in making the program a calculator, we will create a program that long to write all the code to create the display. Start from the outside, forwarded screen, the button 1, button 2, button 3, etc, as well as key operators -, +, x and: = and a button that you create is larger than the others because it is often used.

Well, after you create quite sophisticated in the program, you certainly know that the key is making the process repeated that we can actually make a function with a variable input text will be displayed. (Remember this example is very simplified, so do not protest). So we will create a function key. Here we will make 2 types of key functions, namely small and large button (the button is of course great for the "same as" before that).

Then, after learning oop, then you will create a class called a key. This class is our design so that we can create objects with different key sizes, colors, and the event that occurred when we press the button. With oop, the class we will have a retroactive nature of programming, oop, of course, will help us to create a program based on PHP.

Explanation of the difference between the class with the function is simply the nature oop that we have ever been mentioned in the previous tutorial oop.

With such attributes, the making of the program will be much easier. For example, if you create a program and requires a specific function, you can create your own function or you will find it easier with the Internet. After you download, then you will need to learn the function and how to use it and if necessary modify the core program. This is different from the class in oop. With the class, we only need to know is just.

Explanation of this class will bring us to the explanation that uses everyday objects.

Ok, hopefully this compare with the explanation can help you understand a little oop. Next we will study the concept of thinking in the example object oop with day-to-day. This you need to connect an explanation about the nature of class earlier.

Overview of PHP-OOP

PHP support in addition to structured programming, which you have learned in the basic tutorial of PHP, also supports Object Oriented Programming, or also known as oop. Although support for the oop PHP is not as strong in Java, but PHP is mature enough to support oop. You can get a lot of class that you need on the Internet to create a program for you.

Before I need to submit, that the making of this program based oop will be very useful if you feel to make large-scale program or programs that will often have some small adjustments.

Object Oriented Programming is a way to create an object-based program, meaning you must change the way you think to be based on an object. But before we move labih far, will be introduced first with some new terms that you will often use oop in the class, object, encapsulation, inheritance and polymorphism.

Actual ability of a programming language to support oop determined by their ability to support fifth term I have mentioned in the previous paragraph. May also, or will you ever wondered what the difference between function and class in oop
