Process Timing

I am working on some realtime data acquisition and I want to time a preocess in my program. I need to know how long it takes to Invalidate a whole screen and if I wrote a function how long it takes to process that function..How do I do that ?

Have you looked at the profiling option available for VC5?  It's not overly exciting but it can give you some of the information you might be looking for.

long int howlong = 0;

void function(void)
{
   SetTimer(111, 1L, NULL);
   //1L = 1mS timer
      :
      :
      //do something
      :
      :
   KillTimer(111);
   TRACE("To in function = %ld\n", howlong);
}

void OnTimer(UINT nIDEvent)
{
   // TODO: Add your message handler code here and/or call
 
   howlong++;      
   CDialog::OnTimer(nIDEvent);
   //CDialog::OnTimer() is assuming you have a dialog base app
}

*Probably* a nieve answer.  If I'm not mistaken, the OnTimer function is always the last on the stack of things to do.  You'd probably not get any responses at all.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

If you do find the OnTimer last on the stack you could always use the old favourite PeekAndPmup to allow processing allotment for the timer

I'd still doubt that it would work.

Another function, GetTickCount(), may do better job than SetTimer(), because the former is from the system clock and supposed to be very accurate. However, if you need a stopwatch with time resolution better than 1 msec, both GetTickCount() and SetTimer() are out of scope. For win95/98, the time resolution of SetTimer() is around 20-50 msec, according to my experiments (somebody corrects me if I am wrong).

Thank you tsauy.  That's what I was thinking of!
