Change dragimage DURING drag and drop operation

Hi all,

I've been puzzling on this for quite a while; any help is appreciated. I'm
doing a drag-and-drop operation with a dragimage in a DragControlObject. I
want to be able to change the dragimage DURING the drag-operation. Is this
possible? GetDragImages is called only once, when the drag-and-drop
operation starts, and not after that. I don't think I've ever seen a program
that does this.

I know this extensive article about drag-and-drop with dragimages, but it
does not give an answer to my question:

thanks & best regards,
Erwin Hans
