Delphi XE2 从Excel导入到数据库《LceMeaning》

以下代码经本人在Delphi XE2 下通过编译

uses
  Comobj;

procedure EXCEL1Click(Sender: TObject);
const
  BeginRow= 1;
  BeginCol= 2;
var
  iRE, I :Integer;
  iRow,iCol :Integer; //列、行
  MsExcel, MsExcelWorkBook, MsExcelWorkSheet : Variant;
begin
  try
    if not dlgOpen1.Execute then
      begin
        Exit;
      end;
    if ExtractFileExt(dlgOpen1.FileName) <> '.xls' then
      begin
        MessageBox(0, '请选择正确的Excel文件',PChar('警告！'),MB_OK or MB_ICONWARNING);
        Exit;
      end;
      try
        MsExcel := CreateOleObject('Excel.Application');
      except
        MessageBox(self.Handle,'本机未安装Excel, 请先安装Excel再执行本操作！      ','警告！',0);;
        Exit;
      end;
    MsExcel.visible := False;
    MsExcelWorkBook := MsExcel.WorkBooks.Open(dlgOpen1.FileName);
  except
    Exit;
  end;
  //开始从EXCEL文件读取相关信息 ,并导入到数据库中的表
  try
