Thread: timer class

You can use GetTickCount(), which returns the number of milliseconds since windows started. It's located in windows.h.

If you want the program to run at a constant speed, you can do this:

Code:

DWORD LastTickCount;
DWORD CurrentTickCount;
DWORD TickDelay = 20;  // 50 Fps --> 1000 / 50 = 20

while(ProgramIsRunning)
{
   LastTickCount = GetTickCount();
   DoSomething();
   do
   {
      CurrentTickCount = GetTickCount();
   }
   while((CurrentTickCount - LastTickCount) < TickDelay);
}

<thought>Why is it called GetTickCount() when it actually returns milliseconds, not ticks???</though>

You can also use the stuff in ctime like time(), clock(), things like that. I don't think GetTickCount is portable, so your class would probably only work with windows.
