How to create a Transparent Window

[Sebastien Girard]

Hello,

I am using the IE WebBrowser (shdocvw.dll) inside my form and use it to
display an HTML background in my form. I also want to capture mouse events
that occur on the browser (Mouse Down). To do so, my class implements
IMessageFilter to pre filter messages and do special stuff on Mouse Down
events on the browser. My problem lies in the fact that I can't get the
Handle of the browser, therefore I can't tell whether the mouse events
occurred in the browser window or anywhere else...

Since I can't find any answer on how to get the Handle of the WebBrowser
Control I was thinking of creating a dummy/invisible window over the browser
that would capture mouse events but would not hide the Browser...

If you have any idea on getting the Handle of the WebBrowser Control or on
How to create a transparent Window over my Browser, please let me know.

Thanks

As soon as a window becomes transparent it stops getting the mouse input so
that won't work either.

OK thanks for the head's up, I won't go in that direction...

Not 100% clear on your issue. But this sample discusses
capturing mouse clicks on transparent forms and passing
them throw to the desktop for instances where a user
wants to double click a desktop icon but the form
is on top of it.
