Remarks
To reverse the effect of the Undo method, use the Redo method. For example, if you clear an item and restore it with the Undo method, use the Redo method to clear the item again.
You cannot invoke the Redo method from code that is executing inside the scope of an open undo unit. Code is in the scope of an open undo unit if it is one of the following:
- A macro or add-on invoked by the Visio user interface.
- In an event handler responding to a Visio event other than the VisioIsIdle event.
- In a user-created undo scope. If you call the Redo method from code inside the scope of an open undo unit, it will raise an exception.
The Redo method also raises an exception if the Visio instance is presently performing an undo or redo. To determine whether the Visio instance is undoing or redoing use the IsUndoingOrRedoing property.
You can call the Redo method from the VisioIsIdle event handler because the VisioIsIdle event can only fire when the IsUndoingOrRedoing property is False. You can also call the Redo method from code not invoked by the Visio instance, for example, code invoked from the Visual Basic Editor or from an external program.
