Question

嗨，有开发人员，

我正在尝试使用Progress 4GL将大量数据导出到Excel。我们谈论的是±5500条记录和±170列。问题是这对Excel来说太过分了，它引发了以下错误：Excel error。我可以继续并导出所有数据，但是程序并不完全可以在中间出现错误。

我正在使用以下代码将来自不同CSV文件的所有数据导出到一个单独的Excel文件中，并为每个CSV文件添加单独的工作表：

  /* Initialize Excel file & add new workbook */
  CREATE "Excel.Application" vchExcel.
  vchExcel:SheetsInNewWorkbook = NUM-ENTRIES(ipcSheets,',').
  vchExcel:WorkBooks:ADD().
  ASSIGN vchWorkBook    = vchExcel:WorkBooks:Item(1).

  /* Import each file's data into a new sheet of the workbook */
  Sheet:
  DO iTab = 1 TO NUM-ENTRIES(ipcFiles) ON ERROR UNDO, RETRY Sheet:
      /* Import CSV data into Excel */
      ASSIGN cConnection        = SUBSTITUTE("TEXT;" + gvcExportPath + "csv_files\" + "&1",ENTRY(iTab,ipcFiles))
             vchWorkSheet       = vchExcel:Sheets:ITEM(iTab)
             vchWorkSheet:NAME  = ENTRY(iTab,ipcSheets)
             lResult            = vchWorkSheet:QueryTables:ADD(cConnection,vchWorkSheet:cells(1,1)).

      ASSIGN
          vchQueryTable = vchWorkSheet:QueryTables(1)
          vchQueryTable:FieldNames = TRUE
          vchQueryTable:RowNumbers = FALSE
          vchQueryTable:FillAdjacentFormulas = FALSE
          vchQueryTable:PreserveFormatting = FALSE
          vchQueryTable:RefreshOnFileOpen = FALSE
          vchQueryTable:RefreshStyle = 1
          vchQueryTable:SavePassword = FALSE
          vchQueryTable:SaveData = TRUE
          vchQueryTable:AdjustColumnWidth = TRUE
          vchQueryTable:RefreshPeriod = 0
          vchQueryTable:TextFilePromptOnRefresh = FALSE
          vchQueryTable:TextFilePlatform = 437
          vchQueryTable:TextFileStartRow = 1
          vchQueryTable:TextFileParseType = 1
          vchQueryTable:TextFileTextQualifier = 1
          vchQueryTable:TextFileConsecutiveDelimiter = TRUE
          vchQueryTable:TextFileTabDelimiter = TRUE
          vchQueryTable:TextFileSemicolonDelimiter = TRUE
          vchQueryTable:TextFileCommaDelimiter = FALSE
          vchQueryTable:TextFileSpaceDelimiter = FALSE
          vchQueryTable:TextFileTrailingMinusNumbers = TRUE
          lResult = vchQueryTable:REFRESH
          vchQueryTable:BackgroundQuery = FALSE.


      /* Catch all errors */
      CATCH eAnyError AS Progress.Lang.ERROR:
          RUN disp_mesg(INPUT SUBSTITUTE("ERROR! -> &1",eAnyError:GetMessage(1))).
          RUN adnew_log(INPUT SUBSTITUTE("ERROR OCCURRED!")).
          RUN adnew_log(INPUT SUBSTITUTE("=> &1: &2",eAnyError:GetMessageNum(1),eAnyError:GetMessage(1))).
      END CATCH.
  END.

  /* Save & close */
  vchExcel:Visible = FALSE.
  vchExcel:DisplayAlerts = FALSE.
  vchWorkBook:SaveAs(gvcExportPath + ipcName + '.xlsx',,,,,,).
  vchWorkBook:CLOSE().

  /* Release All Objects */
  RELEASE OBJECT vchQueryTable NO-ERROR.
  RELEASE OBJECT vchWorkSheet  NO-ERROR.
  RELEASE OBJECT vchWorkBook   NO-ERROR.
  vchExcel:QUIT(). /* Quit Excel */
  RELEASE OBJECT vchExcel NO-ERROR.

您是否知道如何解决此问题并获得所需结果？提前谢谢！

为什么从进度控制XL？

如果XL是强制性步骤......我宁愿这样做...用一个宏文件调用XL来打开CSV并以XL格式保存。如果需要将其集成到业务流程中......我只需在生成CSV后立即使用宏文件打开XL。
