bool IVsExpansionFunction::FieldChanged(  
   [in] BSTR bstrField,  
   [out] bool *fRequeryFunction  
);

This method is called when another field in the code snippet is changed, typically because the user edited the field. If this method sets the fRequeryFunction parameter to non-zero (true), the GetCurrentValue method should be called to fetch the updated value for this expansion function.
