How to make a bitmap replace a button when the button gets pressed

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.

What are you using?

WIN32, MFC etc? Easier in MFC.

Button can be hidden / revealed with ShowWindow() (that is the easy bit). I find flat buttons look best in this type of thing (BST_FLAT)

Drawing a bitmap will required some work with Device Contexts and WM_PAINT msgs. I suggest some reading here in the recent threads on 'double buffering' or 'memory DCs'.

I do this sort of thing with 'hot spots'. Process mouse clicks on an image looking for clicks inside parts with PtInRect().

Have a read, get a clear idea of what you want to do and post back with further questions (the more specific the better).

In an MFC dialog based app I would;

Use the resource editor to add a button and configure it (remove WS_VISIBLE so it does not show up)

Add an image control (also not visible) and put both in the same place on the dialog.

In code I would write a handler that called ShowWindow() on these two controls, depending on which we want to see.

I would call the handler from the OnInitDialog() handler making the button visible (and leaving the image invisible).

I would call it again from the OnButtonClick() handler making the button invisible and the image control visible.
