WPF Timer problem… Cannot get correct millisecond tick

Question

I have a basic question regarding timers. My timer is acting very strange. I am trying to make the tick occur every millisecond to update my data. I can get it to work with

This is the code for C#:

using System.Windows.Threading;


public partial class MainWindow
{

    DateTime Time = new DateTime();
    DispatcherTimer timer1 = new DispatcherTimer();

    private void dispatchertimer_Tick(object sender, EventArgs e)
    {
        TimeSpan Difference = DateTime.Now.Subtract(Time);
        Label1.Content = Difference.Milliseconds.ToString();
        Label2.Content = Difference.Seconds.ToString();
        Label3.Content = Difference.Minutes.ToString();
    }

    private void Button1_Click(System.Object sender, System.Windows.RoutedEventArgs e)
    {
        timer1.Tick += new System.EventHandler(dispatchertimer_Tick);
        timer1.Interval = new TimeSpan(0, 0, 0);


        if (timer1.IsEnabled == true)
        {
            timer1.Stop();
        }
        else
        {
            Time = DateTime.Now;
            timer1.Start();

        }
    }

Here is how to do it:

Add 3 labels and 1 button : Label1, Label2, Label3 and Button1

This is the code for Vb(Visual Basic):

Imports System.Windows.Threading

Class MainWindow

Dim timer1 As DispatcherTimer = New DispatcherTimer()
Dim Time As New DateTime

Private Sub dispatchertimer_Tick(ByVal sender As Object, ByVal e As EventArgs)
    Dim Difference As TimeSpan = DateTime.Now.Subtract(Time) 
    Label1.Content = Difference.Milliseconds.ToString
    Label2.Content = Difference.Seconds.ToString
    Label3.Content = Difference.Minutes.ToString
End Sub

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles Button1.Click
    AddHandler timer1.Tick, AddressOf dispatchertimer_Tick
    timer1.Interval = New TimeSpan(0, 0, 0)


    If timer1.IsEnabled = True Then
        timer1.Stop()
    Else
        Time = DateTime.Now
        timer1.Start()

    End If
End Sub
End Class
