Implement CKEditor source code editor in ASP.Net

Hey guys,

Here on the forum, in the TextArea there is a button called Insert Code to insert HTML, JavaScript, SQL, VB, C#, etc. codes. How can I implement this in my system? I use CKEditor to have WYSIWYG HTML in my application but I don't know how to create a way to interpret those codes in it.

How can I do this?

Grateful, Ilano.
