I just needed to add JwaPdh and JwaPdhMsg, and it worked beautifully! This topic (performance counters in Delphi) is really really small on the Internet - the only Delphi code example available, that does not use the HKEY_PERFORMANCE_DATA, is yours! And your piece of code absolutely rocks! If I want to add another performance counter to the query (for example disk activity or similar), how should I go about adding it? Should I make the wildcard search broader or how should I approach adding more counters to the code? Best regards, Michael Your website rocks! Hi,

Maybe you need to enable it separately when installing D2005? You could also try using just the necessary sub-units (e.g. JwaPdh in this case) instead of the entire JwaWindows library.

It is seriously the best Delphi article about performance counters on the Internet! However, when my delphi (2005) tries to compile JwaWindows, it says that I do not have msxml.dcu: [Fatal Error] JwaWindows.pas(213): F1026 File not found: 'msxml.dcu' I have tried searching for it online, but I can't seem to find it. Can you help me? :) Best regards, Michael Hi

I tried to find some kind of language-independent algorithm for constructing the pattern when I wrote the above application, but (if I recall correctly) nothing useful came up. Unfortunately not.

Try using the ANSI/ASCII version - PdhExpandWildCardPath<strong>A</strong> - instead. Your Delphi version is probably the cause – I’d guess the default string type doesn’t support Unicode, right?
