I am able to do a drag&drop into my dialog, however I cannot detect that the mouse was released over my field.
The BFM_DRAG_FINISHED or the BFM_DRAG_LOST doesn't seem to be correct.

What is the best way of doing this?
I am using Cinema 4D 11.5

oDialog::Message(msg)
{
if (msg->GetId() == BFM_DRAGRECEIVE)
{
    println ("Drag message ontvangen.");
    if (CheckDropArea(DRAGDROP, msg, TRUE, TRUE))
    {
        var string;
        var obj=GetDragObject(msg);
        if (instanceof(obj,BaseObject))
        {
            string=obj->GetName();
            SetString (DRAGDROP, string);
            println ("The mouse is in DRAGDROP and dropped.", string);
            // The mouse is in drop area.
        }
        else println ("Wrong type was dragged.");

        //if (msg->GetData(BFM_DRAG_FINISHED)) println ("Finished."); // does not work???
    } // end mouse is in drop area.

if (msg->GetData(BFM_DRAG_LOST)) // never seem to get here???
    {
        println ("lost...........");
        // We are no longer the target of the drag operation.
        // Remove or reset any help text/lines.
    }
} // end if (msg->GetId() == BFM_DRAGRECEIVE)

return super::Message(msg);

} // end Message
