I had this problem when trying to do drag-and-drop within a tree-view control. We went round and round with Microsoft support. We kept working our way up the Microsoft Developer support heirarchy until we were connected with a real ringer. VFP adn VB expert. He wrote a small VB DLL which returns NOTHING and built the solution around that. So, we did a CREATEOBJECT on the little VB blurb and we could get a NOTHING tag from it.

Problem was, by the time we got the solution, we'd already finished the application and cashed the check! :)
