        ' Draw the track bar. 
        Protected Overrides Sub OnPaint(ByVal e As PaintEventArgs)
            If Not TrackBarRenderer.IsSupported Then 
                Me.Parent.Text = "CustomTrackBar Disabled" 
            End If 

            Me.Parent.Text = "CustomTrackBar Enabled"
            TrackBarRenderer.DrawHorizontalTrack(e.Graphics, _
            TrackBarRenderer.DrawTopPointingThumb(e.Graphics, _
                thumbRectangle, thumbState)
            TrackBarRenderer.DrawHorizontalTicks(e.Graphics, _
                ticksRectangle, numberTicks, EdgeStyle.Raised)
        End Sub 

        ' Determine whether the user has clicked the track bar thumb. 
        Protected Overrides Sub OnMouseDown(ByVal e As MouseEventArgs)
            If Not TrackBarRenderer.IsSupported Then 
            End If 
            If Me.thumbRectangle.Contains(e.Location) Then
                thumbClicked = True
                thumbState = TrackBarThumbState.Pressed
