Description | Handle the dragEnter message to perform an action (for example, display a special cursor or set the acceptDrop property) when the mouse pointer enters an object. The dragEnter message is sent only when a drag and drop operation is in progress. If two controls overlap, a dragEnter message is sent whenever the mouse pointer crosses into a visible portion of a control. The control on the bottom receives a dragEnter message only when the mouse pointer enters part of the control that can be seen. A control that is completely hidden by another control on top of it will never receive a dragEnter message.
