Undo - Redo

Can anyone tell me how to Undo or Redo the steps.

No.

The undo / redo functions are almost entirely depentent on the nature of your application. Things like textboxes have their own Undo buffer, but other than that you have to write most of it yourself.

I am using a drawing function to draw on a picture box and i want this to be Redoed or Undoed. Can you please help me?

Thanks
