Hello, I am working on a small home project and need the very best calculation between a time interval. Now i have programmed: dtStartTime = DateTime.Now 'start 'do other things and then.... dtEndTime = DateTime.Now 'endtime 'extracting the seconds and millisecs sSeconds = (dtEndTime.TimeOfDay - dtStartTime.TimeOfDay).Seconds.ToString sMilliSeconds = (dtEndTime.TimeOfDay - dtStartTime.TimeOfDay).Milliseconds.ToString 'and put it back together dblSecsAndMsecs = CType((sSeconds + "." + sMilliSeconds), Double) My question is : Is there a better way to do this.?. Ellen

I'm not going to claim that it's "better", but I THINK it is...

        Dim dtStartTime As DateTime = DateTime.Now
        'Do stuff
        Dim tsEndTime As TimeSpan = DateTime.Now.Subtract(dtStartTime)
        Debug.Print(tsEndTime.Seconds & "." & tsEndTime.Milliseconds)

Hey Have you tried the optimised system.diagnostics.stopwatch class Chris posted here: http://forums.netdui...topwatch-class/ Its in C# but there are online converison tools like the one here: http://www.developer...t/csharp-to-vb/ Should give you greater resolution than you have now. Nak.

Have you tried using DateTime.Subtract? This returns a TimeSpan object that has both values that can then be used. Cheers

After a lot of tests, this works indead very well.
Thank you.
