Alok, I think you didnt read carefully(:

The textbox is in html page. There is a webbrowser control and it has a textbox(in html page) and then in form, there is a button. When a user write "example" in textbox(in html page), and then click the button, I want to catch this "example".

string txt = ...................; ----> txt must be what user write in textbox.
