) : int

Parameters

  • bstrField
    Type: System.String

    [in] Name of the field that changed.

  • fRequeryFunction
    Type: System.Int32%

    [out] Returns non-zero (true) if this expansion function's value has changed and must be re-obtained; otherwise, returns zero (false).

Return Value

Type: System.Int32
If the method succeeds, it returns S_OK. If it fails, it returns an error code.

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.
