I'm writing an application, that should
show a live video (from pc camera) on one window,
and another window with some control on it,
should appears below it.
I'm using 'IVideoWindow' Interface from DirectShow.
This window should be semi transparent.
I think that the AlphaBlend() SDK should do that work,
but I couldn't find how to connect it with IVideoWindow.
* The use of IVideoWindow is not mandatory
* OS win2000
* DirectX 7
* Code in C++
Waiting for advises
