how to automate axwebbrowser to click checkbox & buttons

[cgchris99]

I have been reading the messages about automating the navigation for a webbrowser control. However, most appear to be for VB6 not vb.net

I know I can fill in a text control like this
AxWebBrowser1.Document.forms(0).All("UserAccount").value="xyz"

But how do I click a checkbox?

If there are muliple buttons, how do I click the one I want?

Thanks for any advice
