Drag n Drop for CTreeCtrl

I have a class derived from CTreeCtrl and I want it to support OnDragOver and OnDropEx.  The wizard supports OnBeginDrag, but not OnDragOver or OnDrop.  What does it take?

You're supposed to handle the drag functions yourself. In this case, OnMouseMove and OnLButtonUp. When the BeginDrag gets called, you need to capture the mouse and set the cursor appropriately and set a flag.

Then in OnMouseMove, if the flag is set, you can highlight certain items by using selecting the drop target.

Finally, in OnLButtonUp, if the flag is set you can "drop" the items. But you need to do all of this yourself.

I guessed this much.  CTreeView can do it, there doesn't seem to be a good reason for CTreeCtrl to lack the ability.  I suspect there is a way to do it, but am not going to waste any more time on it.
