Which technology are you using, GDI or GDI+? And which OS is this on?
And in which video mode? Video driver? What does your current code look
like?

1. Help: Transparent window with transparent bitmap
Hi there,
I was wondering if anyone could help me out on this one. I'm creating a
window
without border nor title (sprite style). Then I Bitblt a bitmap of the
same size
as the window on it. Now I would like that a well defined part of the
bitmap
would be transparent, therefore displaying the contents of whatever
window is
behind the actual window.
I read the MSDN article about transparent bitmaps, but it didn't help me
much.
Anyone got an idea? (Please only C/C++ and pure win32, NO MFC)
Mike
