The following code example demonstrates how to create a VisualStyleRenderer with the VisualStyleElement returned by the Normal property. To run this example, paste it into a Windows Form. Handle the form’s Paint event and call the DrawVisualStyleElementScrollBarUpperTrackVertical1 method from the Paint event-handling method, passing e as PaintEventArgs.

Public Sub DrawVisualStyleElementScrollBarUpperTrackVertical1(ByVal e As PaintEventArgs)
    If (VisualStyleRenderer.IsElementDefined( _
     VisualStyleElement.ScrollBar.UpperTrackVertical.Normal)) Then
        Dim renderer As New VisualStyleRenderer _
          (VisualStyleElement.ScrollBar.UpperTrackVertical.Normal)
        Dim rectangle1 As New Rectangle(10, 50, 50, 50)
        renderer.DrawBackground(e.Graphics, rectangle1)
        e.Graphics.DrawString("VisualStyleElement.ScrollBar.UpperTrackVertical.Normal", _
          Me.Font, Brushes.Black, New Point(10, 10))
    Else
        e.Graphics.DrawString("This element is not defined in the current visual style.", _
          Me.Font, Brushes.Black, New Point(10, 10))
    End If
End Sub
