I tried a lot of differnet multi undo solutions, but every had at least one draw back. So I had to write my on solution and I think my one is quite smart.

If you want to use it, you don’t have to clutter your code by pasting in lots of undo-related subs, functions and variables. Everything comes within two small class files.

All you have to do is to create one class instance and set the richtextbox/textbox you want to enhance with multiple undos. It will look something like this:
```
	Dim WithEvents Undo as clsUndo
	Set Undo = New clsUndo
	Undo.AssignToRichTextBox Controls, RichTextBox1
```
That’s basically all you have to do.

  Jack, simply copy the clsUndo.cls and clsUndoElement.cls class files into your VB project. Then create a new Undo instance as described above and assign it to a text box. Next create undo/redo buttons or menu items that call the undo / redo functions of the Undo class.
  
  Hope that helps,
  Seb
