Question

I want to add a label that prints the elapsed time like a normal clock (when seconds reachs “59” then add “1” min to the counter) but my time span add minutes when the seconds reaches the number “30”… what I’m doing wrong?

    Dim ElapsedTime As TimeSpan

 While log_button.Text = "Stop logger"
            ElapsedTime = Now().Subtract(StartTime)
            Label5.Text = String.Format("Minutos transcurridos: {0:00}:{1:00}", CInt(ElapsedTime.TotalMinutes) Mod 60, CInt(ElapsedTime.TotalSeconds) Mod 60)
            Application.DoEvents()
 End While

I get a wrong incrementation like this:

00:01

…

00:28

00:29

00:30

01:31

01:32

etc…

Answer 1

That’s because you are rounding the floating point number that represents total minutes. When the numbers reaches 0.5 it will be rounded to 1.

Use the Floor method to truncate the number:

CInt(Math.Floor(ElapsedTime.TotalMinutes)) Mod 60

You can also use the Minutes property, that does all that:

ElapsedTime.Minutes
