Description
Handles exceptions during variant type conversions.
HandleConversionException handles exceptions resulting from attempts to convert between variant types. Code that implements such conversions should call HandleConversionException when a conversion throws an exception.
ASourceType and ADestType indicate the variant types of the source and destination. HandleConversionException uses these to format an appropriate error string. If the current exception corresponds to a variant exception, HandleConversionException raises that exception. Otherwise, HandleConversionException simply re-raises the original exception.
