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:

      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;
