Ok I cannot continue to bother you with my questions about how drawing into a picture box with OwnerDraw set if I really can't figure out what CDC is, what HDC stands for or why BitBlt wants a CDC pointer instead of a matrix of pixels.

So.. suggest me a good book or tutorial to learn how to draw things with CDC / HDC / BitBlt / StretchBlt things in MFC.

I am willing to learn, I'll study by myself and then try to write my own code. If and only if I am having more problems, I'll bother you again.

Thank you for your patience
