• 如何将几个DBGRID里的内容导入同一个EXCEL表中?


    前言:

      在软件实际制作中,为节省开发成本和开发周期,一些软件人员通常会吧DBGrid中的数据直接导出到Excel表中,而先前能看到的函数仅仅只能在WorkBook的一个Sheet中导入数据,不支持多Sheet!。

    单元应用:

    Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
    Dialogs, StdCtrls, DB, DBTables, Grids, DBGrids, ActiveX, ComObj,
    Excel2000, OleServer;

    测试环境:

      OS:Win2k Pro;Excel2k;Delphi6.0

    源程序:  

    {
    功能描述:把DBGrid输出到Excel表格(支持多Sheet)
    设计:CoolSlob
    日期:2002-10-23
    支持:CoolSlob@163.com
    调用格式:CopyDbDataToExcel([DBGrid1, DBGrid2]);
    }

    procedure CopyDbDataToExcel(Args: array of const);
    var
      iCount, jCount: Integer;
      XLApp: Variant;
      Sheet: Variant;
      I: Integer;
    begin
      Screen.Cursor := crHourGlass;
      if not VarIsEmpty(XLApp) then
      begin
        XLApp.DisplayAlerts := False;
        XLApp.Quit;
        VarClear(XLApp);
      end;

      try
        XLApp := CreateOleObject(‘Excel.Application‘);
      except
        Screen.Cursor := crDefault;
      Exit;
      end;

      XLApp.WorkBooks.Add;
      XLApp.SheetsInNewWorkbook := High(Args) + 1;

      for I := Low(Args) to High(Args) do
      begin
        XLApp.WorkBooks[1].WorkSheets[I+1].Name := TDBGrid(Args[I].VObject).Name;
        Sheet := XLApp.Workbooks[1].WorkSheets[TDBGrid(Args[I].VObject).Name];

        if not TDBGrid(Args[I].VObject).DataSource.DataSet.Active then
        begin
          Screen.Cursor := crDefault;
          Exit;
        end;

        TDBGrid(Args[I].VObject).DataSource.DataSet.first;
        for iCount := 0 to TDBGrid(Args[I].VObject).Columns.Count - 1 do
          Sheet.Cells[1, iCount + 1] := TDBGrid(Args[I].VObject).Columns.Items[iCount].Title.Caption;

        jCount := 1;
        while not TDBGrid(Args[I].VObject).DataSource.DataSet.Eof do
        begin
          for iCount := 0 to TDBGrid(Args[I].VObject).Columns.Count - 1 do
            Sheet.Cells[jCount + 1, iCount + 1] := TDBGrid(Args[I].VObject).Columns.Items[iCount].Field.AsString;

          Inc(jCount);
          TDBGrid(Args[I].VObject).DataSource.DataSet.Next;
        end;
      end;

      XlApp.Visible := True;
      Screen.Cursor := crDefault;
    end;
