How to Install Windows 7 from PenDrive (USB Flash drive)

Today i’ve to install winodows 7 in my Dell Vostro 3400. I collect a Windows 7’s DVD but some days ago i lost my optical (DVD) drive. So i was thinking to install Windows 7 from USB key.

How to customize CKEditor’s Image dialog Window

I think you already know about CKEditor. If not, you can get details from their site. I only quoted a portion from their site-

CKEditor is a text editor to be used inside web pages. It’s a WYSIWYG editor, which means that the text being edited on it looks as similar as possible to the results users have when publishing it.

Accessing HTML element from CodeFile/ Code Behind page in ASP.NET

In ASP.NET all HTML elements are treated as text by default. The Parser simply passes them to the client (e.g. Web browser) without processing. So from CodeFile (e.g khaled-info.aspx.cs) we can’t access them.

This tells the web server to process the element at page rendering time. The “id” attribute is need to be added to identify the server control. The “id” reference can be used to manipulate the server control at run time.
