'使用
Dim instance As ExpansionFunction
Dim bstrField As String

public:

[OutAttribute] int% fRequeryValue
)
public function FieldChanged(
bstrField : String,
fRequeryValue : int
) : int
Parameters
bstrField
Type: System.String[in] The name of the field that was changed.
fRequeryValue
Type: System.Int32%[out] Returns nonzero if the expansion function depends on the value of the specified field and needs to be re-queried; otherwise, returns zero.
Return Value
Type: System.Int32
If successful, returns S_OK; otherwise, returns an error code.
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.
