Disable Undo/Redo temporarily

[tomr]

Hi Sergey,
I was wondering if there is a possible way to disable undo/redo temporarily. I want to make changes to a richedit and the specific changes should not be part of the undo list. Nevertheless i do not want to clear the undolist completly. Is there a lock function or anything else, I could use?

Best regards
Tom

Tom, (not from Sergey!!)

I know you can use this:
Property UndoLimit sets the capacity of undo buffer. It can be used to disable undo/redo feature.

You'd probably have to set it to the current undo count:

Code: Select all

TRVEditRVData(rv.RVData).UndoList.Count

Maybe that will do it?

Hi Stan,
I really appreciate your help. I have tried your suggestion and it works fine. I was not sure if setting the count to 0, would reset the undo list.
It does not. After setting the count back to the count I saved temporaily my undo list was correct

Thank you.
Best regards
Tom
