Exporting data to Excel from Axapta through code (x++)

Hi All!
Sometimes we need to export data from Microsoft Dynamics AX to Excel using axapta x++ code and we don't know how to do this...
Exists some differents ways to do this, but I think the best way is using the SysExcel class of Dynamics AX and its related.
The only problem I found using this class... is that it can not be used in a batch process.
Sample code:

static void TheaxaptaCreateExcel(Args _args)
{
   SysExcelApplication  xlsApplication;
   SysExcelWorkBooks    xlsWorkBookCollection;
   SysExcelWorkBook     xlsWorkBook;
   SysExcelWorkSheets   xlsWorkSheetCollection;
   SysExcelWorkSheet    xlsWorkSheet;
   SysExcelRange        xlsRange;
   CustTable            custTable;
   int                  row = 1;
   str                  fileName;
   ;
   //Filename
   fileName = "C:\\Test.xlsx";
   //Initialize Excel instance
   xlsApplication           = SysExcelApplication::construct();
   //Open Excel document
   //xlsApplication.visible(true);
   //Create Excel WorkBook and WorkSheet
   xlsWorkBookCollection    = xlsApplication.workbooks();
   xlsWorkBook              = xlsWorkBookCollection.add();
   xlsWorkSheetCollection   = xlsWorkBook.worksheets();
   xlsWorkSheet             = xlsWorkSheetCollection.itemFromNum(1);
   //Excel columns captions
   xlsWorkSheet.cells().item(row,1).value("Account Num");
   xlsWorkSheet.cells().item(row,2).value("Name");
   row++;
   //Fill Excel with CustTable AccountNum and Name fields (only 20 records)
   while select custTable
   {
      if(row == 20)
        break;
      xlsWorkSheet.cells().item(row,1).value(custTable.AccountNum);
      xlsWorkSheet.cells().item(row,2).value(custTable.Name);
      row++;
   }
   //Check whether the document already exists
   if(WinApi::fileExists(fileName))
      WinApi::deleteFile(fileName);
   //Save Excel document
   xlsWorkbook.saveAs(fileName);
   //Open Excel document
   xlsApplication.visible(true);
   //Close Excel
   //xlsApplication.quit();
   //xlsApplication.finalize();
}
