    [CustomAction]   
    public static ActionResult FillServerInstances(Session xiSession)
    {         
        xiSession.Log("Begin CustomAction");

        xiSession.Log("Opening view");
        View lView = xiSession.Database.OpenView("DELETE FROM ComboBox WHERE ComboBox.Property='DBSRVR'");
        lView.Execute();

        lView = xiSession.Database.OpenView("SELECT * FROM ComboBox");
        lView.Execute();

        int Index = 1;
        bool flag = false;
        try
        {
            foreach (DataRow dr in Microsoft.SqlServer.Management.Smo.SmoApplication.EnumAvailableSqlServers(false).Rows)
            {
                String InstanceName = dr["Name"].ToString();

                if (InstanceName.Equals(xiSession["ComputerName"] + @"\" + xiSession["SQLINSTANCENAME"], StringComparison.InvariantCultureIgnoreCase))
                { flag = true; }

                Record lRecord = xiSession.Database.CreateRecord(4);
                xiSession.Log("Setting record details");
                lRecord.SetString(1, "DBSRVR");
                lRecord.SetInteger(2, Index);
                lRecord.SetString(3, InstanceName);
                lRecord.SetString(4, InstanceName);

                xiSession.Log("Adding record");
                lView.Modify(ViewModifyMode.InsertTemporary, lRecord);

                ++Index;
            }
        }
        catch (Exception ex)
        {
            logException(xiSession, ex);              
        }
        if (flag)
        {
            xiSession["DBSRVR"] = xiSession["ComputerName"].ToString() + @"\" + xiSession["SQLINSTANCENAME"].ToString();
        }

        lView.Close();

        xiSession.Log("Closing view");
        lView.Close();
        return ActionResult.Success;       
    }
