Just follow two steps for clicking a any button using code.

focus the button or element which you want to click

WebBrowser1.Document.GetElementById("place id here").Focus()
simulate mouse click using this following code

SendKeys.Send("{ENTER}")

You could try giving an ID to the form  in order to get ahold of it  and then call form submit   from a Javascript call
