Comments
The DragStarting event occurs when the beginning of a drag & drop operation has been detected.
The DragStarting event only occurs when the OLEDragMode property is set to OLEDragSftControlManual. An application can implement its own drag & drop processing or use the OLEDrag method in response to this event.
The CurrentFolder property can be used to determine where the drag & drop item starts. It typically includes all selected folders, which can be retrieved using the Selection property and the SelectionCount property.
