Public Function OnElementValueChanged (elementid As UInteger, varValueOld As Object, varValueNew As Object) As Integer

Parameters

elementid: UInt32

[in] DWORD value representing a particular entry in the array of element values associated with the selection context. For valid elementid values, see VSConstants.VSSELELEMID.

varValueOld: Object

[in] VARIANT that contains the previous element value. This parameter contains element-specific data, such as a pointer to the IOleCommandTarget interface if elementid is set to SEID_ResultsList or a pointer to the IOleUndoManager interface if elementid is set to SEID_UndoManager.

varValueNew: Object

[in] VARIANT that contains the new element value. This parameter contains element-specific data, such as a pointer to the IOleCommandTarget interface if elementid is set to SEID_ResultsList or a pointer to the IOleUndoManager interface if elementid is set to SEID_UndoManager.

Returns

Int32

If the method succeeds, it returns S_OK. If it fails, it returns an error code.
