Having a Program Monitor Its Own CPU Usage

I am looking for a way to have a program monitor its own CPU usage.  Can anyone describe how I may do this (code would be appreciated as well)?  I am trying to write the program in C using Microsoft Visual .Net.  Thanks.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

You can call GetCurrentProcess() to get your your own process handle and then use GetProcessTimes() to find out how much time was spent by your process.

If you want to get a percentage value similar to those displayed in task manager you can use the Performance Data Helper API:

There is a discusssion about this and a code sample at the end of this articte:
