Question

How can I programatically find the CPU time which is displayed in System Idle Process (in Task Manager) using Visual C++?

Answer 1

What you want is something like this…

NTSTATUS hStatus; SYSTEM_PERFORMANCE_INFORMATION             stSysPerfInfo;  hStatus = NtQuerySystemInformation(SystemPerformanceInformation, &stSysPerfInfo, sizeof(stSysPerfInfo), NULL); if (hStatus != NO_ERROR) {   // Do work.... } 

Or take a look at this ‘TaskManager’
