as above

trying to do two things

1) an undo button for my application so that once i zoom in on a fractal i can zoom back out.. pretty much similar to how the back button works on IE

2) save the state i.e. save the current state of the aplication so that when i load it again, it redraws to where you left and you can continue zooming in

any sample code that can help me?

cheers

ps. im not an expert so needs to be easy to follow lol

1. create yourself an undo class, which basically is a lifo stack. Add your new settings each time you click 'go'. you should also have a method to pull from the stack.

2. you could use the registry or a local file to save state.

there'll be plenty of sample code on planetsourcecode.com
