Implements

IVsExpansionFunction.FieldChanged(String, Int32%)

Remarks

This method is called to determine if the expansion function needs to recalculate its value if the value depends on the specified field.

This method is an implementation of the FieldChanged method on the IVsExpansionFunction interface.

The base method searches the list of arguments for a matching field. If the field is found, the base method set fRequiryFunction to 1 and returns S_OK; otherwise, the base method sets fRequiryFunction to 0 and returns S_OK.
