Getting performance data from the registry (like CPU load)

Last Modified: 2010-04-04
I'd really like to be able to get the performance data from the registry, this data is stored under the HKEY_PERFORMANCE_DATA key and should be accessible through standart registry calls, I have made the call to get the large gob of data from the registry, I just need to make sense of it, I'd like to get the CPU load, but also other data in time.
The documentation of the data is contained in the M$ helpfile called win32sdk.hlp (or something) under the title Performance Data Helper (PDH) and is horribly lacking in detail and hard to understand, in that help file there is also a C++ example of how to dismantle the data returned, I just havn't go the energy to translate it...

I'd like to try and translate it for you, but, since i access Experts-Exchange at work, where there's no Delphi, would you mind posting the offending help page here?

I have already translated the example from the helppage myself,
the example from the help file doesn't write out the values of the performance counters, I tried that myself, but it seems that I didn't translate the records correctly, by translating the file winperf.h I hope to get the records aligned correctly.

Well, I'm still having some trouble with it, so if someone has a nice Class for delphi that makes it all sugar coated I'd really like it before I start coding one myself...
