);
Parameters
- nNumButtons 
 Number of button images in the bitmap.
- nBitmapID 
 Resource identifier of the bitmap that contains the button image or images to add.
- pBitmap 
 Pointer to the CBitmap object that contains the button image or images to add.
Return Value
Zero-based index of the first new image if successful; otherwise – 1.

You can use the Windows API CreateMappedBitmap to map colors before adding the bitmap to the toolbar. If you pass a pointer to a CBitMap object, you must ensure that the bitmap is not destroyed until after the toolbar is destroyed.
