What's the best way to handle running one application on many different machines with different screen resolutions?

Specifically, I want to be able to run all my forms on my machine with a screen resolution of 800x600 and with a screen resolution of 1024x768.

My maximum design area is set to 800X600 when I build my project. This gives me a maximum form height of 569 and a max form width of 790.

With a screen resolution of 1024x768 this is fine.

With a screen resolution of 800x600, I can't get to the bottom of my forms. The forms are too big for the screen.

What's the best by to handle this? We need to be able to run the app in any resolution.
