'Declaration
Function OnElementValueChanged ( _
elementid As UInteger, _
varValueOld As Object, _
varValueNew As Object _
) As Integer
'Usage
Dim instance As IVsSelectionEvents
Dim elementid As UInteger
Dim varValueOld As Object
Dim varValueNew As Object
Dim returnValue As Integer
returnValue = instance.OnElementValueChanged(elementid, _
varValueOld, varValueNew)
int OnElementValueChanged(
uint elementid,
Object varValueOld,
Object varValueNew
)
int OnElementValueChanged(
[InAttribute] unsigned int elementid,
[InAttribute] Object^ varValueOld,
[InAttribute] Object^ varValueNew
)
function OnElementValueChanged(
elementid : uint,
varValueOld : Object,
varValueNew : Object
) : int
Parameters
elementid
Type: System.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
Type: System.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
Type: System.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.
Return Value
Type: System.Int32
If the method succeeds, it returns S_OK. If it fails, it returns an error code.
