On Windows NT, use the PDH (Performance Data Helper) API.
On Windows 95, your'e on your own ;-)

Hi guys, I think there was even a way to determine the CPU load that some particular thread causes, or am I wrong here? That might be encouraging, but I'm afraid that's all I can help with :) BTW you saw Billy's "System Monitor", right?

Hi,

[ Win95 and NT store bunches of performance data in a special "virtual" branch of the registry, HKEY_PERFORMANCE_DATA (NT)
or HKEY_DYN_DATA (Win95). The format is different for NT and Win95 and sparsely documented. You can find something in the win32.hlp file if you search the index for things that start with PERF. ] from Peter Below.

Luckely for you, there exists an example (for NT) :

http://www.wilsonc.demon.co.uk/Delphi%20Components/pviewer/D3/pviewer.zip (D3)

Matvey, what is Billy's "System Monitor"...?

Regards, Zif.

Ooh, hi Tom! Glad you're back, I'm also having a plenty of holidays here :) How was your trip?

I meant the standard windows system monitor, that should be (if you chosen to install it in the beginning) in Accessories/System Tools/System Monitor.
Found it? It's kinda` simple progy that shows different graphs of the memory usage, CPU usage HD, etc.
I also saw some programs that calculated their own CPU usage - I'm not sure how they do it though: it might be internal calculations of what it THEORETICALLY does, and how much CPU it'll take, or there might actually be a standard way to find it out for each thread how much CPU it uses.
