        // Draw the standard header background.
        e.DrawBackground();

        // Draw the header text.
        using (Font headerFont =
                    new Font("Helvetica", 10, FontStyle.Bold))

    ByVal e As DrawListViewColumnHeaderEventArgs) _
    Handles listView1.DrawColumnHeader

    Dim sf As New StringFormat()
    Try

        ' to Left if it has not been set to Center or Right.
        Select Case e.Header.TextAlign
            Case HorizontalAlignment.Center
                sf.Alignment = StringAlignment.Center
            Case HorizontalAlignment.Right
