I am developing a simplified Microsoft word application. I am using a Memo for the user to type in a document. I am not sure how to create an Undo or Redo function does anyone have any ideas?

Thanks

Hi myleseven1,
What is your programming environment? VBA?

One way would be to create a stack, a type of collection. Every action a user does generates an entry in the stack(push). When he does Undo, you then remove the last entry in (pop).  You are then left with a stack containing all actions done so far expect the last one... I think it's the easiest way to do it.
