Hi,
I'm doing a performance test on calling a function in different situation. I record the start and end time to a DateTime variable, and calculate the no. of seconds elapsed using Datediff function.
However, I found that it only accurate to seconds, if the different is less than 1, it will became 0. How can I measure the time in more accurate way?
Thx!
hmm how are you using DateTime as a counter? show me I wanna know :DQuote:

QueryPerformanceFrequency
QueryPerformanceCounter
umm anyways I did this in C# with the TimeSpan object and it works fine, gives the miliseconds too. Try using it...
a = new TimeSpan(DateTime.Now.Ticks);
b = new TimeSpan(DateTime.Now.Ticks);
b= b.Subtract(a);
MessageBox.Show (b.Seconds.ToString() + " " + b.Milliseconds.ToString());
HoHo...Don't laugh me.
I just record the current time using Now, and Datediff.........
oh got you... I wasnt laughing at you hahaQuote:
