Hi,
Our PowerPoint addin will perform some operations that we don't want user to
undo/redo. To stop users from performing undo, we want to clear the undo
list.
In word, I can clear the undo list with a method call: Document.UndoClear().
But in PowerPoint, there is no such method. In web, somebody suggested
calling ActivatePresentation.Save to clear the undo list. This is the only
way I can find. But our addin MUST NOT save the powerpoint automatically.
So,to me, it seems there is no way to clear the undo list in PowerPoint.
My question is:
1) Do you know how to clear undo list w/o saving PowerPoint file?
2) Or,rather than clearing undo list, is there other way that I can stop
user from undoing some of our operations?
Sincerely
