I ama bit confuse on your question.
I know that WebBrowser component embeds an HTML page in VB Forrm,hence if you have an event that is initiated on that html page is by default captured by vb.Now here is What I think you should do.
in the form load sub of your vb form that has WebVrowser object on it
initialise the WebBrowser object
A WebBrowser object has an event called
in this sub initialize the HTMLDocument object like this
Dim html As IHTMLDocument2
Set html = web.Document
Set htmlDoc = html
Once you have done this, then you have the ability to use htmlDoc with all the events that a web page generates
onclick,onmouseover,onmousemove and so on.....
I hope thats what you wanted to know, Good Luck either way.
you'd be better off posting your question on some VB forum
