How do I programmatically find the CPU usage of another process in Windows NT & W2K?

see working code in

Thanx, but..
I wanted to find the CPU usage of 'a particular process' at the current time and not the total CPU usage at the current time.(in Win NT & W2K) The CPU is of the Intel family of processors.

PS> I already have the Codepile.com stuff with me but it gives the total CPU usage only.

Or, you want for every thread. In such case see
http://www.edm2.com/0607/cpu.html

That solution is only for OS/2 Warp I guess as the article goes. I wanted one that works for WinNT 4.0 and Win2K both!
I guess I mentioned it.

The article talks of only OS/2 Warp 3.0 and 4.0 nothing Microsoft about it!

Moreover I cannot use undocumented features in windows for the fear of future compatibilty.

Also, I am nearing on another different solution here, hopefully it should be over this week.

Thanks.

The information you want is in the performance counters of the system. There are API functions for reading this. Unfortunately they're not the most intuitive. There were some articles using performance counters recently in MSDN/MSJ magazine. Try searching the knowledge base at http://msdn.microsoft.com for information on reading performance counters. Incidentally you can also create your own counters if you have the need.

I'm sorry this isn't much help, but I haven't had the need yet to do this myself, so I don't know the specifics. But at least this should point you in the right direction.

Come to think of it, the articles I was thinking of were in Windows Developers Journal, but here are some similar articles from MSJ:

Part 1: general and for VB

and

Part 2: more specifics and for C/C++
