Alex,

you could also concider to use the multimedia timer. It has the greatest
resolution which is possible for the hardware platform. Look for
timeSetEvent() etc.

Gerd,

Or QueryPerformanceCounter(...) and QueryPerformanceFrequency(...), both
are defined in 'WinBase' of the 'Win32 API Library'. Get a copy of the
CPU28 library (from the GrafX 3rd party ftp site) and you will be able
to perform integer calculations on the results from these calls.

Regards,
Frans.

METHOD ...
LOCAL struPerformanceFrequency IS _WinLarge_Integer
LOCAL struElapseTime IS _WinLarge_Integer
LOCAL struStartTime IS _WinLarge_Integer
LOCAL struStopTime IS _WinLarge_Integer
LOCAL fElapsed AS FLOAT

QueryPerformanceCounter(@struStartTime)

...
... // Do some work

QueryPerformanceCounter(@struStopTime)

QueryPerformanceFrequency(@struPerformanceFrequency)

U6464Sub(@struElapseTime,@struStopTime,@struStartTime)
fElapsed:=FLOAT(struElapseTime.LowPart)/FLOAT(struPerformanceFrequency.LowPart)

_DebOut32(String2Psz("Time(Sec)=>"+Str3(fElapsed,10,6)))

Frans,

thank you, I will have a look at it.

Hi France

> U6464Sub
Where i can found this function ?
