Transparent BMP

[Rafael Fernandez Lopez]

How can I insert into my project dialog a BMP from a resource and make it transparent ? I set up my BMP background to (255,0,255) and it doesn't turn to transparent. Should I call any function or something ? Thanks in advance, Rafael.

Are you using the BitBlt function to render the image? In that case you shold switch to TransparentBlt. As far as I remember the last parameter to the function is the transparent color...

no I'm not using it, I don't even know what is it. I am programming with MFC but until now I ever have programmed graphical interfaces and what function should I call from MFC ?? Please help or tell me some web site where it is explained or something... thank you so much !!
