How Code-Behind Files are Connected to web Pages in ASP.NET

Normally start of every aspx pages is referenced to the language and specific code behind file to excite the web page’s controls and events if it is not in a code-Inline structure. In traditional ASP.NET it is using Src attribute to point out the source code file or inherit attribute indicate the compile class name. In these both two approaches have several impairments when considering each other. But common problem is, both may add boilerplate code because of every time have to indicate web control with a member variable in these two methods.

To overcome this problem ASP.NET provides oversaw keyword called partial, which has a capability to spit a single class into multiple source code files. Essentially, the model is the same as before, but the control declarations are shuffled into a separate file. You, the developer, never need to be distracted by this file; instead you can just access your web-page controls by name.

In code behind file:

public partial class TestFormCodeBehind : System.Web.UI.Page{ ... }

Debugging PHP with Netbeans

Most of the PHP developers are complaining that they have not a good ID for PHP debugging and every time that they have to use var_dump() print statement or PHP die or exit commands to check the state of php script. But now we can use netbeans to overcome this issue with netbeans-xdebug. I tried this with Linux and feel that working it cool. Anyway still I had not a time to try out this with windows and hope that netbeans-xdebuger working fine with windows also. Now I am going to explain how we can enable netbeans-xdebuger in Ubuntu 1.

To Configure xdebuger with php and netbeans ID. open php.ini file using this command; sudo gedit /etc/php5/apache2/php.ini A...

In 1980, A computer scientist called Richard Stallman decided to create a venerable operating system called Unix. At the time Unix ran many of industrial and academic system in the world. He started developing Unix operating system and most of the world wide people join with him to success this operating system. Stallman called his version as "GNU" (Pronounced G-noo).
