BMP Button??

Well if you have the button set as a child, then what you could do is catch the WM_LBUTTONDOWN for when the left mouse button is clicked down and WM_LBUTTONUP for when the button is released. So it would be something like this:

case WM_LBUTTONDOWN   //Left Mouse Button Down
{
  if(hwnd == ThehwndOfYourButton)
  {
    BitBlt(hdcofbutton, 0, 0, btnwidth, btnheight, hdcofBitmap, 0, 0, SRCCOPY);
    break;
  }
  default:
      break;
}


case WM_LBUTTONUP   //Left Mouse Button Up
{
  if(hwnd == ThehwndOfYourButton)
  {
    BitBlt(hdcofbutton, 0, 0, btnwidth, btnheight, hdcofBitmap, 0, 0, SRCCOPY);
    break;
  }
  default:
      break;
} 

You will have to either make your bitmap and DCs global or rewrite your hdc and SelectObject code in each case, because you will not be resending the messages to WM_PAINT.

If you dont know what the hdc of the button is you can use

HDC hdc;
hdc = GetDC(hwndOfTheButton);

first you forgot the : after each case. second it doesn't seem to catch when the leftmousdown or mouseup. i even tried just making it popup a msgbox when it was clicked rather than setting the pic. that didn't work either. my button is WS_CHILD. it doesn't work. i got the picture to be painted on my button but like i said it won't catch the mouse events. what could be wrong ? if u would like i'll send u the code. but i'm not a beginner. well i am to bitblt. but not to c++ win32.

Yeah I wrote that hole thing from memory so I have no doubt that I would forget something like the :. That would be fine with me. [email protected]
