.Net - WebBrowser Control

Hi

I am facing two problem with WebBrowser control.
1. How to insert an HTMLElement object at current mouse location in WebBrowser.Document.Body?

2. How to avoid the alert message that i am getting while resetting DocumentText property? The alert message appears something like this: "Document is changed... Do you want to Save?"

Any help would be highly appreciated.

Thanks in advance!
