time difference

Dim starttime As DateTime
Dim finishtime As DateTime
Dim elapsed As TimeSpan

starttime=now()
some processing
finishtime=now()
elapsedtime=finishtime.subtract(starttime)
messagebox.show(???????????????)

what would I show in the message box if I wanted a message like 1:37 to
indicate it took 1 hr and 37 minutes to run some processing.

I've displayed minutes before but this event could be between a minute
and a few hours.

I guess I could do elapsed.hours & ":" & elapsed.minutes

Is that the best way?

Hello cj,

Give elapsedtime.ToString() a shot and see if that's what you want.

Thanks,
Mark

TimeSpan.ToString() always use a fixed format to output the string, such as
00:00:02.0001664.

To get the customized format, you could just either use string concat or
use string.Format:

Message.Show(string.Format("{0}:{1}", elapsed.Hours, elapsed.Minutes))

cj,
In addition to the other comments.

I will convert the TimeSpan to a DateTime if I need custom Formatting:

Dim seconds As Integer = 75
Dim elapsed As TimeSpan = TimeSpan.FromSeconds(seconds)

> elapsed = finishtime.subtract(starttime)

Dim value As DateTime = DateTime.MinValue.Add(elapsed)
Dim s As String = value.ToString("mm:ss")

> messagebox.show(???????????????)

Hope this helps
