Calculating speed using distance/time problem

[yilmaz]

hi
I recently coded a program which displays the timespan between 2 different times. I used the DateTime function to do this but now i can't calculate the speed as you cannot use DateTime in division, is there another function i should use?
This is my code so far:

 
Public Class Form1
    Dim starttime As DateTime
    Dim endtime As DateTime
    Dim timetaken As TimeSpan
    Dim registration As String
    Dim Distance As Integer
    Dim speed As Decimal


    Private Sub btnOK_Click(sender As Object, e As EventArgs) Handles btnOK.Click
        starttime = DateTime.Parse(txtStart.Text)
        endtime = DateTime.Parse(txtEnd.Text)
        timetaken = endtime - starttime
        registration = txtReg.Text
        Distance = 500

        speed = Distance / timetaken

    End Sub
End Class

You could use DateTime.Ticks

But you should verify that starttime and endtime are on the same date.

I believe you're in the wrong forum. That looks like VB.Net code, and this is the VB6 (very old pre-dotnet version) forum. That's probably why you haven't seen much of a response.

Speaking strictly from a VB6 perspective, I would have suggested using the DateDiff() function to get the difference as a number of known units - most likely seconds. But I have no idea what the VB.Net equivalent would be. Perhaps a search for something like "datediff VB.Net equivalent" would be fruitful.
