if your doing it with
vb then what you can do is create an instance of the web browser control, load it up with the web page, create and instance of HTMLDocument equate that to the web browser (I can't remember how to do it exactly) and then you can start manipulating the controls on the page, even catch a button press and get it to do what you want.
If you need more info in the way of code, reply, and I'll get it to you by tuesday (21st apr)
