Handling Events

Applies to: Excel 2013 | Office 2013 | Visual Studio

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

CalculationEnded and CalculationCanceled are not raised during programmatic recalculation.
