Multiple Stopwatches and dynamically naming variables

[jameswobrien]

Hi,

I am trying to make a program to allows me to record times for certain events.
I was thinking of using the system.diagnost ic.stopwatch class to do this.

What i need to do is be able to use a for loop to create an X (user defined) number of stopwatches, each one called L and then the number of the stop watch.

Then i need to press a button and it reads the value of another variable (F), and then stops the clock of L(F).

Im not sure if this is possible and how to do it.

Your help will be greatly appreciated

Thanks james

Well, how about making an array of them. Then you could read in F and stop L[F]. That should work. Just remember that arrays are zero-based, so if F is not zero based, you would want to stop L[F - F_base]. So if F starts at 1, you want to stop L[F - 1].

something like this? I have left it very simple but it basically creates x ( starting at '0' ) number of stopwatches and starts them and then when you click on button 2 it stops the one ( without error checking ) that has the number entered in textbox1.text

 Dim x, f As Integer
    Dim l As New ArrayList




    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        x = 5

        For n = 0 To x
            l.Add(New System.Diagnostics.Stopwatch)
            l(n).Start()
        Next
        Timer1.Enabled = True

    End Sub

    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        f = TextBox1.Text
        l(f).stop()
        MsgBox(CType(l(f), System.Diagnostics.Stopwatch).Elapsed.Seconds)
    End Sub


End Class
