Using C# or C++ how can you change a computer monitor's color and brightness settings?

Question

How to change computers colour settings and screen brightness?

I'm creating an application and part of it I want to be able to click a button to change the screen brightness of your monitor. I also want to be able to change the colour settings so I can flick from colour to black and white/grey scale.

I was originally going to use .NET but I really don't think that's possible at all.

I can't work out how to actually change a computers settings. Can anyone help?

Welcome to StackOverflow! For screen brightness settings, I'll refer you to the following questions:

• C# setting screen brightness Windows 7
• Adjust screen brightness using C#
• How to detect when screen brightness or system volume changed?

For color settings, once again we can use WMI: http://msdn.microsoft.com/en-us/library/Aa394512 (prior to Vista, use http://msdn.microsoft.com/en-us/library/Aa394512)
