I am making a application in microsoft visual basic 2008 express edition using VB.net as the programming language.

What I want to do is get the contens of a textbox on my webbrowser by using GetElementByID then putting the contens into my RichTextBox1 I'm not sure how I would do this so can you help please.

I think that I need to but the contens to string then do RichTextBox1.Text = stringname


Thanks,
Cyberdemon1337 :D
