You do not need to manually call the BeginUndo, EndUndo or CancelUndo methods when calling methods from this AnnAutomation object directly. The AnnAutomation object will internally do this for you. For example, when you call the Delete method to delete the object(s) currently being edited, the AnnAutomation object will perform the above sequence internally to add the undo node.
Use the UndoCapacity property to get or set the number of user actions that can be reversed using the Undo method, or re-applied using the Redo method. The default for the UndoCapacity property is 10 actions.
For more information, refer to Undoing Automation Operations. (Deprecated)
For an example, refer to BeginUndo.
