ADOQuery1->SQL->Text = "select * from SEC_S_LSI_Logic_Power_CSR";
                  ADOQuery1->SQL->Add("order By 순번");
-->            ADOQuery1->Open() 으로 변경
                  while(!ADOQuery1->DataSource->DataSet->Eof)
-->            while(!ADOQuery1->Eof)

                  {
                          CSR_No = ADOQuery1->DataSource->DataSet->FieldByName("CSR_접수등혹번호")->AsString;
-->                     CSR_No = ADOQuery1->FieldByName("CSR_접수등혹번호")->AsString;

                          CSR_No = CSR_No.Trim();

                          if(CSR_No != "")
                          {
                                  Form5->ComboBox1->Items->Add(CSR_No);
                          }
                  }
                  ADOQuery1->Open();
-->             ADOQuery1->Open(); <-이줄은 삭제하고 ADOQuery1->Close();
