Automatic resizing of a FormView based application when the user toggles the control bars on or off.

I'm a software developer from Sweden who got tired of snow and cold weather and moved to USA. I choose New York City, so I wouldn't totally miss out on snow and cold weather. I work on Wall Street with financial systems (not much else to do in this neighborhood). I primarily use Visual C++/MFC or C#/.NET as development tool.
