                  {
                                 this.openConnection(conType, conStr);
                  }
                  public void openConnection(string conType, string conStr)
                  {
                        //Case resasign dbConn and open connection
                        switch(conType)      
                        {        
                              case "sqlclient":
                                    // use constructor to open the connection
                                    SQLdbConn = dbConn;
                                    dbConn = new SqlConnection(conStr);
                                    dbConn.Open();

               {
                    //Case resasign dbConn and open connection
                    switch(conType)      
                    {        
                         case "sqlclient":
                              // use constructor to open the connection
                              SQLdbConn = dbConn;   // you are using dbConn here
                              dbConn = new SqlConnection(conStr);  // you are declaring dbConn here
                              dbConn.Open();                    
                              break;

Just switch the two around. so that your switch looks like this:

 switch(conType)      
                    {        
                         case "sqlclient":
                              // use constructor to open the connection
                             
                              dbConn = new SqlConnection(conStr);  // you are declaring dbConn here
                              SQLdbConn = dbConn;   // you are using dbConn here
                              dbConn.Open();                    
                              break;
