The UndoItem2 class inherits from the UndoItem class and supports all the UndoItem properties and methods. An object that supports UndoItem might not necessarily support UndoItem2 .

You can also use the UndoItem2 interface to make an edit to a TestStand file undoable if the UndoItemCreator does not provide enough functionality to undo an edit. To do this, create a COM object that implements the UndoItem2 interface and send an instance of the object to the sequence editor using a UIMsg_PushUndoItem UI Message.
