Relates to the DD_EnterDrag, DD_DragOver and GD_Drop events.
This property specifies what action would be performed if the user released the mouse button at the current position. It is updated by the destination object (located beneath the mouse pointer), with the DD_EnterDrag and DD_DragOver events.
It is used by the system to determine the shape of the mouse pointer, and by the destination object with the DD_Drop event.
Drag and drop operations can only be successfully completed if the destination object accepts a copy or move action with the DD_DragOver event.
