Comments

The DragStarting event occurs when the beginning of a drag & drop operation has been detected.

The DragStarting event only occurs when a drag & drop operation is detected. A drag & drop operation is initiated by pressing the left mouse button on the current selection.

The application can start an OLE drag & drop operation in response to other events by using the OLEDrag method.
