Programatically controlled CBitmapButton's

I have a non-modal dialog containing several CBitmapButton controls. In the message handlers for the buttons in the dialog I set the button state. First I iterate through all buttons and removes the pushed state by calling SetState(FALSE). Then I set the pressed button by calling SetState(TRUE). It works fine, until the keyboard is touched. When any key is pressed, the state is reset and all buttons are depressed, which I don't expect to happen. No function that programatically changes the state are called. Why does this happen, and how can I fix it?

Your easiest solution is to copy the CBitmapButton code into your project (it's relatively small) and override the mechanism for loading and displaying the images.  Then instead of doing the SetState functions, create yourself a new function that will replace the 'Up' bitmap with the 'Down' bitmap.

I found another way by overloading the CBitmapButton's PreTranslateMessage, and returning TRUE without calling the default handler if pMgs->message is WM_KEYDOWN or WM_KEYUP. That is perhaps even easier.
