Determines whether or not the Drag-Drop Event will be suppressed for the dialog or dialog element. If it is suppressed, the dialog or dialog element will not get control when a drop occurs over the dialog or dialog element during a drag-drop operation.
For OLE drag-drop operations, the status of this attribute also determines whether a drop is currently possible when the dialog or dialog element is defined as a drop target (see the DROP-MODE attribute) and the drag cursor enters or traverses the area occupied by the dialog or dialog element during a drag-drop operation. If it is suppressed, a "no drop" drag cursor is displayed and no drop is allowed, even if the DROP-MODE attribute value would otherwise allow it. Therefore, by dynamically updating the status of this attribute during a drag-enter and/or drag-leave event, you can temporarily inhibit or allow a drop depending on the current context (e.g., position within the dialog or dialog element).
