A button, like most of the windows controls, sends notification messages to the parent window when events occur. When a button is clicked, it sends a WM_COMMAND message where the lower-order word of the wParam is the button's id, the higher-order word of wParam is BN_CLICKED, and lParam is a handle to the button.
See the documentation for more info.
If you want the control's ID, use the LOWORD macro.

Look at this:
That "103" right there: that's the ID you've assigned the button. When you get a WM_COMMAND message from a control, such as a button, the lower-order word of the wParam is this ID you've assigned the control. This is all covered in the documentation for WM_COMMAND, as well as in the documentation for the control notification messages. If you get this ID by using the LOWORD macro, you should be able to determine which control sent it.
hBtn = CreateWindow( "BUTTON", "a", WS_CHILD|WS_VISIBLE|BS_PUSHBUTTON, 50, 50, 100, 25, hWnd, (HMENU)103, hInst, NULL );That "103" right there: that's the ID you've assigned the button.

You've already specified the bitmap style, you just need to set which bitmap the button should use. You do this by sending the button a BM_SETIMAGE message.
HANDLE hBitmap = LoadImage( hInstance, "buttonImage.bmp", IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE );SendMessage( hBtn, BM_SETIMAGE, IMAGE_BITMAP, hBitmap );This topic is closed to new replies.
