Clearing the Undo Stack in a Macro

Summary: When writing a macro, you may need a way to clear the undo stack. This can be done with a single command, as described in this tip. (This tip works with Microsoft Word 97, Word 2000, Word 2002, Word 2003, and Word 2007.)

Normally, as you are making edits in your documents, Word keeps track of what you do. Word does this so you can later use the Undo and Redo commands on the toolbar. What if you are developing a macro, however, and you don't want the user to be able to undo changes? In this case, you can use the UndoClear method in your macro, as follows:

ActiveDocument.UndoClear

In this usage, UndoClear wipes out the Undo stack (the list of actions that is remembered by Word) for the active document. Note that this affects only those actions that have been recorded so far; any new actions will be duly recorded and available on the stack.

Tip #739 applies to Microsoft Word versions: 97 | 2000 | 2002 | 2003 | 2007
