Hi,
I didn't realize that it was opening IE - I thought it remained hidden. If
you require IE to be visible then WebClient won't help you at all since it's
not associated with a browser.
I tried your code, with some slight modifications to get it to build, and
none of the events were raised for me either. I tested with IE7,
exclusively.
The fix shown in the following article didn't work either, but it's
interesting to note and supplies some code that supposedly fixes a problem
that seems similar to what you are experiencing:
BUG: The BeforeNavigate2 Event of WebBrowser Control Does Not Fire If Hosted
in a Visual C# .NET Application
http://support.microsoft.com/kb/325079/EN-US/
I tested my own version of the code found in the article above using the
DWebBrowserEvents2 interface instead of DWebBrowserEvents. The code appears
after my signature. Some of the events are raised, so I suspect that this
may have something to do with the fact that IE7 uses tabs now but I'm not
sure how to solve the problem. Maybe my code will give you somewhere to
start :)
