如何快速的将查询结果存成Excel文件(100分)

各位大虾,我使用Delphi 6的Query控件查询Sql Server 2000数据库后,用 Dbgrid控件显示数据,用Excelapplication生成excel文件时速度非常慢.那位先进可否指点一二,在下不声感激.

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.VObject).Name;
Sheet := XLApp.Workbooks[1].WorkSheets[TDBGrid(Args.VObject).Name];

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

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

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

Inc(jCount);
TDBGrid(Args.VObject).DataSource.DataSet.Next;
end;
end;
XlApp.Visible := True;
Screen.Cursor := crDefault;
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
CopyDbDataToExcel([DBGrid1, DBGrid2]);
end;

用Ado连接Excel速度很快的，看李维的Ado/MTS/Com+高级程序设计篇：）

接受答案了.
