Handling Events

Published: July 16, 2012

Starting in Excel 2010, XLLs can receive events designed to manage the asynchronous function life cycle. The events are as follows:

  • CalculationEnded: Raised when Excel is finished calculating. After this event, you can free resources allocated during the calculation.

  • CalculationCanceled: Raised when the user interrupts the calculation. The XLL stops any asynchronous activities. Immediately following this event, the CalculationEnded event is raised.

To handle these events, the XLL uses the C API function xlEventRegister.

Note Note

CalculationEnded and CalculationCanceled are not raised during programmatic recalculation.
