Creates a new drag image by combining the given image (typically a mouse cursor image) with the current drag image.
BOOL SetDragCursorImage(
   int nDrag,
   CPoint ptHotSpot 
);
Parameters
- nDrag 
 Index of the new image to be combined with the drag image.
- ptHotSpot 
 Position of the hot spot within the new image.
Return Value
Nonzero if successful; otherwise 0.
Remarks
Because the dragging functions use the new image during a drag operation, you should use the Windows ShowCursor function to hide the actual mouse cursor after calling CImageList::SetDragCursorImage. Otherwise, the system may appear to have two mouse cursors for the duration of the drag operation.
