XLL+ Class Library (7.0)


Called by the framework when the user changes the contents of a cell

virtual void OnSheetChange(
   LPDISPATCH dispWorksheet,
   LPDISPATCH dispRange



Pointer to dispatch interface of type Excel.Worksheet.


Pointer to dispatch interface of type Excel.Range, representing the new selection.


This function is called whenever the user changes the contents of a cell.

Note that it will only be called if event-sinking is switched on (using CXllApp::SetSinkEvents()).

You can override the method in your application class to react to the event. The default method does nothing.

Implementation note

You should only implement this function if you need access to Excel's COM interfaces. To handle events, you should usually use the event model. If you particularly need to call an add-in function to handle the event, use the much simpler mechanism provided by CXllApp::SetComEventHandler().
