Question

So I’m getting closer and closer to making the timer work the way I want it to, with one small problem.

I found the following post about returning millisecond and nanosecond:
How do you convert Stopwatch ticks to nanoseconds, milliseconds and seconds?

But what I’m trying to do is show only the 10ths of 100ths of a second when desired.

I have the following code:

Private Sub TotalTimer_Tick(sender As System.Object, e As System.EventArgs) Handles TotalTimer.Tick
    Dim elapsed As TimeSpan = Me.matchStopwatch.Elapsed

    Me.MatchClockLbl.Text = String.Format("{0:0}:{1:00}:{2:00}.{3:###}", _
                                   Math.Floor(elapsed.TotalHours), _
                                   elapsed.Minutes, _
                                   elapsed.Seconds, _
                                   (elapsed.Milliseconds / 100))

End Sub

Now I tried to change the part of code from {3:000} to {3:0} or {3:00} but all this does is change format, it doesn’t actually remove the 1000ths digit or 1000ths digit, they still show up.

I further found this on the MSDN:

But I keep getting s.f or s/f or something that’s not right.

EDIT: Added in the modified version of the code, thanks Oded. The new problem now is that the label likes to flicker the extra digits once in a while.

Answer 1

Divide Milliseconds by 10 to get 100th of a second and by 100 to get 10th of a second.

This works by integer division – essentially throwing away the least significant digits and assumes Milliseconds returns at most 3 digits.
