CPU load indicator without ActiveX


Recommended Posts

Hi, I tried it, it works, but only if you have .NET installed. Not everyone has this, so I would rather have a way that works on all common configurations. Is there no API-call to kernel32.dll or something similar?

NtQuerySystemInformation used to be the popular way of getting the right information. MS now recommend using other functions though (linked on the same page). Not sure how easier it's going to be to get LabView to handle the datatypes...

This CodeProject page might also be of some assistance.

Another approach which may or may not be better is to use the PDH.DLL (Performance Data Helper) functions. Can't remember what the general availability is (might need to distribute the DLL with your app?). They query the performance counters, which are sorta designed for this task, so they might be the best bet.

cheers,

Tom
