Question

I am looking a Tool on How to Find CPU Utilization of a Single Thread within a Process in VC++.

It would be great full if any one could provide me a tool.

Also it could be better if you guys provide how to do programmatically.

Thank you in Advance.

Answer 1

Perhaps using GetThreadTimes would help ?

To elaborate if the thread belongs to another executable, that would be something (not tested) in the lines of:

// Returns true if thread times could be queried and its results are usable,
// false otherwise. Error handling is minimal, considering throwing detailed
// exceptions instead of returning a simple boolean.
bool get_remote_thread_times(DWORD thread_id, FILETIME & kernel_time, FILETIME & user_time)
{
  FILETIME creation_time = { 0 };
  FILETIME exit_time = { 0 };
  HANDLE thread_handle = OpenThread(THREAD_QUERY_INFORMATION, FALSE, thread_id);
  if (thread_handle == INVALID_HANDLE) return false;

  bool success = GetThreadTimes(thread_handle, &creation_time, &exit_time, &kernel_time, &user_time) != 0;

  CloseHandle(thread_handle);
  return success;
}
