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;
