Here is a word document that explains how to do it.

>Good afternoon the whole ones.
>I am with a problem in the use of Drag&Drop. When I drag an item of a " LIST " for a " TREEVIEW " I need to know the reference of the knot. The problem is that the event " HITTEST " always comes back me a null value, what turns impossible to know the correct reference. I already tried to place it in " DRAGOVER " and " HITTEST ", but it doesn't work.
>Which the appropriate form?
