// Draws column headers.
private void listView1_DrawColumnHeader(object sender,
    DrawListViewColumnHeaderEventArgs e)
{
    using (StringFormat sf = new StringFormat())
    {
        // Store the column text alignment, letting it default
        // to Left if it has not been set to Center or Right.
        switch (e.Header.TextAlign)
        {
            case HorizontalAlignment.Center:
                sf.Alignment = StringAlignment.Center;
                break;
            case HorizontalAlignment.Right:
                sf.Alignment = StringAlignment.Far;
                break;
        }

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

        // Draw the header text.
        using (Font headerFont =
                    new Font("Helvetica", 10, FontStyle.Bold))
        {
            e.Graphics.DrawString(e.Header.Text, headerFont,
                Brushes.Black, e.Bounds, sf);
        }
    }
    return;
}

' Draws column headers.

    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
                sf.Alignment = StringAlignment.Far
        End Select

        ' Draw the standard header background.
        e.DrawBackground()

        ' Draw the header text.
        Dim headerFont As New Font("Helvetica", 10, FontStyle.Bold)
        Try
            e.Graphics.DrawString(e.Header.Text, headerFont, _
                Brushes.Black, e.Bounds, sf)
        Finally
            headerFont.Dispose()
        End Try

    Finally
        sf.Dispose()
    End Try
