About Application.OnUndo again

[pk]

Hi there,

I've found that calling Application.OnUndo method clears all the Undo
history, so this method appears unuseful. Maybe there is a way to keep the
history and use Application.OnUndo method only to place custom Undo method on
the top of the Undo stack?
More over if I call Application.OnUndo in OnUndo handler, it doesn't place
new handler on the stack.

Most macros that do anything destroy the undo/redo stack (along with the
clipboard).

If you want to control an undo, maybe you can take care of it yourself.

The example only demonstrates using Application.OnUndo method, nothing more.
I would like to use custom undo handlers only for my methods, something like
this:

StartTrackingChanges();
RunOperation();
FinishTrackingChanges();
Application.OnUndo(undoComment, "UndoOperationChanges");

Otherwise I'll have to fully implement my own undo/redo functionality, and
don't use Application.OnUndo at all.
