I use a different solution, derived from the Win32 API, which is accurate to
about 5 milliseconds. Here it is :-
void mjdelay(unsigned int msecs)

{

  unsigned int nw;

  timeBeginPeriod(5); nw=timeGetTime();

  do { Sleep(5); Application->ProcessMessages();} while
(timeGetTime()-nw<msecs);

  timeEndPeriod(5);

}

| Hello, i need to count in milliseconds, but that count must to be exact.
| I'm using the Sleep function but is not always the same result....
|
|         InitTime = GetTickCount();
|         Sleep(25);
|         MittleTime = GetTickCount() - InitTime;
|
| Hier MittleTime is 3 or 4 times 31 or 32 (i assumed that +/- 7 millis is
| what the function need to get and give the time)... and some oder times 15
| or 16 (so, less time than the specified ni the Sleep function).
|
| what can i do to get always 25 ml of delay? I read something about
| Multimedia timers... can i get with it the right timing ?
