any idea
vb or fasm or masm code, all welcome (except .net code)
what i think now is sending the button handle from vb to fasm dll for it to process (add png file on top of it)

what u guys think?

Since in C# (.NET) you can assign a png to a button, it is possible. But I couldn't tell you if uses its own mapping routine with owner draw, or converts to bitmap I've never really looked into it.

sleepsleep, check out miranda-im source code, you will find how to convert png into dib (device independent bitmap) in memory and then it's quite easy to put dib onto button, that's all

ps: c++/c code

ps: i've already made buttons based on gif and bitmaps, now you give me idea to write png support, but png decoding requiring zlib and pnglib, they are pretty huge

k, thanks vasilev & redghost
i would try to find and read some more
