I'd be interested in seeing what you come up with. I meant no offense. PdhOpenQuery(NULL, 1, &m_hQuery); PdhAddCounter(m_hQuery, "\\Process(FineSpeak)\\% Processor Time", 0, &m_hIVRCounter); PdhCollectQueryData(m_hQuery); PdhGetFormattedCounterValue(m_hIVRCounter, PDH_FMT_LONG, NULL, &stFormattedValue); // stFormattedValue.longValue = CPU usage. Thanks.

For GetSystemTimes(), I think your only solution is to use the officially-unsupported function NtQuerySystemInformation (http://msdn.microsoft.com/en-us/library/ms724509(VS.85).aspx, look for SYSTEM_PROCESSOR_PERFORMANCE_INFORMATION).

Here is a partial list of some of them: http://undocumented.ntinternals.net/ Maybe I'm just splitting hairs but unsupported means they plan on replacing the function eventually where as undocumented means you probably

Thus, the equation is There are two APIs that are useful: GetProcessTimes – Get times for a specific process GetSystemTimes – Get total times for the entire system (all CPUs) The the WTM's high refresh (250 milliseconds?) normal (1 second), and low (4 seconds) might actually factor in millisecond time. C++ Get Cpu Usage Windows Each process spends some time in kernel mode and some time in user mode. Getsystemtimes help me!!!

Attached File - example.bmp(image for problem) Thanks. the task manager uses native api calls for the process times, I know it calls NtQuerySystemInformation (passing SystemProcessesAndThreads enum) which would contain the processes kernel/user time, I would assume the PdhGetFormattedCounterValue Check This Out Dezo3-Aug-07 10:11 Dezo3-Aug-07 10:114 see $subj View the 3 replies to this messageSign In·Permalink how to get the CPU usage data using Turbo C++?

I need to modify this to get me the CPU % used by a particular process…for example, I need to monitor the CPU Usage for "iexplore". Pdhaddcounter I think the millisecond thing is kind of screwing up any chance of sync (using date udf to check intervals). How do I use this? | Other CB clients Other Users?

This requires the use of the http://msdn.microsoft.com/en-us/library/ms724400 GetSystemTime DLLCall to retreive the following: IdleTime KernelTime UserTime System time = kernelttime + usertime So CPU Usage can be calulated as such.
