Hello There, I want to write a program where there are a series of buttons, and when a given button is pressed, the button is replaced by a bitmap, however, I am a little unsure where to start when it comes round to coding that (I'm just getting to grips with the basics of win32 programming, this is a learning exercise). I have a feeling that because I want to swap the button with a bitmap when the button gets pressed, I may have to code it so that the buttons are declared at runtime, instead of them being declared at compilation, although I can't really get much further than that, any help would be appreciated.
