        private void ThisAddIn_Startup(object sender, System.EventArgs e)
        {
        uc1 = new UserControl1();
        Share.ctp1 = this.CustomTaskPanes.Add(uc1, "acReport");

    private void ctp1_visibleChanged(object sender, System.EventArgs e)
    {

        RibbonXML1 ribbon = Globals.Ribbons.GetRibbon<RibbonXML1>(); 
        ribbon.toggleButton1.Checked = Share.ctp1.Visible;
    }
    private void ctp1_DockPositionChanged(object sender, System.EventArgs e)
    {
        Globals.ThisAddIn.Application.StatusBar = Share.ctp1.DockPosition.ToString();
    }

    private void ThisAddIn_Shutdown(object sender, System.EventArgs e)
