Transparency

How is it possible to paint a picture with transparencies onto a container? (I am looking for a method like PaintPicture, but this does not support transparency. Picture format does not matter.)

Thanks in advance.

note: I do not want to use DirectX.

I think there's an API called TransBlt that would work, I don't have the declaration for it though.

Or you could use use bitblt twice, invert and and

imagelistview is handy but drains performance, if you don't need any critically, just put your images into it and draw them with the draw method
