VB.NET WebBrowser click on button

Question

I am working at a small VB.NET project which autofill the fields on the Yahoo register page. Is there a way to click on "Check" button and see if the entered ID is OK or not?

Something like if the entered ID is OK then proceed further with filling the field, if not, try another ID and press "Check" button again.

Solution

The webbrowser control lets you access elements within the webpage and you can invoke methods on them, so something as simple as this will click the button:

webBrowser1.Document.All("yidHelperBtn").InvokeMember("click");

Indeed, as John said, you can also replace ' CheckButton.Focus() SendKeys.Send("{ENTER}") ' by WebBrowser1.Document.All("yidHelperBtn").InvokeMember("click‌​") It will do the same thing; however, you still have to wait for 1sec after the document is completed
