Parameters

bstrField

Remarks

COM Signature

From textmgr2.idl:

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.
