I'm looking to automatically kill a process if it gets over a certain CPU percentage. I need to know what API function to call to get the CPU percent.

I already know how to get a list of processes.

Thanks. It looks like you have to get the kernel/user times of all processes and do some math.

Unsure if this will help, but it appears that WMI (Windows Management Instrumentation) may provide a means of doing this:

If you have not already done so, I suggest checking other web sites, such as StackOverflow.com

Hi Roland;

  FWIW: Have a look at my STD Framework's "Windows Explorer" App. It can locate any process and kill it ...

http://chrispollach.blogspot.com/2024/02/explorer.html

The Explorer works in either M-Code or P-Code compiles and either 32 or 64 bit mode.

The framework is Free & open Source, so feel free to use my code as applicable.   HTH  ;-)

Regards ... Chris

Chris,

I think you missed the point that Roland is trying to find the CPU usage for a given process BEFORE his app decides if it needs to kill it.

Yes, just add something like this then into the processing Roland wants to do ...
