I have an event handler for the TextBox.TextChanged event on a form of mine. In order to support undo, I'd like to figure out exactly what has changed in the TextBox, so that I can undo the change if the user asks for it. (I know the builtin textbox supports undo, but I'd like to have a single undo stack for the whole application)
Is there a reasonable way to do that? If not, is there a better way of supporting such an undo feature?
