2. Add a variable for the button, type: cbitmapbutton (manual modification required)
3. During InitializationProgramAdd the followingCode:
(Cbitmapbutton *) getdlgitem (Button ID)-> loadbitmaps (the ID of the image displayed when the button is available,
The ID of the button that is pressed when the button is available,
The ID of the image displayed when the button is unavailable,
When the button is unavailable, press the button ID );
(Cbitmapbutton *) getdlgitem (Button ID)-> invalidate (true );
(Cbitmapbutton *) getdlgitem (Button ID)-> sizetocontent ();
4. Set the properties of the button-> styles-> owner draw.
