Remarks

OLEGiveFeedback is a drag source event that lets you provide visual feedback to the user. You can change the mouse cursor to indicate the operation that occurs when the mouse is positioned over the drag source or the drop target. Including NODEFAULT has no effect on the behavior of this method.

Note that you should avoid creating wait states in the OLEGiveFeedback event with commands and functions such as WAIT WINDOW and MESSAGEBOX( ).
