XLL+ Class Library (7.0)


Gets a reference to the WorkbookBeforeClose event

CXlWorkbookBeforeCloseEvent& WorkbookBeforeCloseEvent( );

Return Value

The function returns a reference to the application's WorkbookBeforeClose event, which is of type CXlWorkbookBeforeCloseEvent.


The WorkbookBeforeClose event is raised when a workbook is about to be closed, and allows the event to be cancelled. All registered observers receive the event via the CXlEventObserver::Update method.

When observers are notified, an argument of type CXlBeforeCloseEventArgs is passed. Observers can cancel normal processing of the double-click by cancelling the event using CXlBeforeCloseEventArgs::SetCancel(false).


Observers can register for this event at any point in the life of the XLL. Registration can be done explicitly using Register, or automatically by creating an instance of CXlWorkbookBeforeCloseEventStaticObserver.
