    Re: [VB6] Register any control as a drop target that shows the Explorer drag image

    1) Assuming you mean dropping onto targets registered using this method?
    -If you're dragging and dropping files, use the SHDoDragDrop API normally.
    -For other formats, see this project.

    2) That error is named DRAGDROP_E_ALREADYREGISTERED; you sure it hasn't been made a drop target in any other way? I can't seem to reproduce it; can register forms fine. OS version, and since it's saying already registered, can you drop on it, and if so does it show the cDropTarget image or does the OLEDragDrop/DragDrop method fire when you drop?
