Undo

[Eric Dreksler]

Hi,

Similar to my last post on drag-and-drop, does anyone know of any good
resources on how to create a good Undo implementation for an application.
I've been wanting to include this feature in my apps, but haven't been able
to find any good info on good ways to implement this kind of feature in a
program.

Thanks in advance,
Eric Dreksler

Some pointer: how about a collection filled with a simple structure
containing an undo-description (String) and a delegate to a function
which undoes a chosen function?

There is no 'general' way of doing this.

What exactly do you want to "undo"?
