        '  Use full opacity for this demonstration.

        '  DesktopAlertLinkClicked event fires when they are clicked.

        showInfo.Text = String.Format("<a>{0}</a>", "Text")
        showInfo.FooterText = String.Format("<a>{0}</a>", "FooterText")

        '  client area, and the sound that is played as the window appears.
        showInfo.Image = new Icon( "C:\Icons\DesktopAlert.ico" ).ToBitmap()

        '  desktop alert window with a unique key.
        showInfo.Key = "MyWindow"
