One way to clear the undo history and then turn it back on would be:

 

acDocManager->sendStringToExecute(acDocManager->curDocument(),L"_UNDO _C _N _UNDO _A _ON ");

 

You could probably also use acedCommand to invoke the same set of command tokens.

Sorry, I dont get the problem you seem to be having with the code provided by Stephen.

You can try what Stephen has mentioned directly using AutoCAD as follows :

 

1. Create a few circles

2. Launch "undo" command

3. Specify "Control" keyword

4. Specify "None" keyword

5. Launch "undo" command

6. Select "All" keyword

 

All the entries from the undo list is cleared.
