我明白楼主的意思了。
procedure TForm1.Button3Click(Sender: TObject);
var
sImage: TfrxComponent;
begin
frxReport1.FileName := 'c:/1.fr3';
sImage := frxReport1.FindObject('Memo1');
(sImage as TFrxMemoView).Text := '财务联';
frxReport1.PrepareReport(False);
sImage := frxReport1.FindObject('Memo1');
(sImage as TFrxMemoView).Text := '仓库联';
frxReport1.PrepareReport(False);
sImage := frxReport1.FindObject('Memo1');
(sImage as TFrxMemoView).Text := '销售联';
frxReport1.PrepareReport(True);
frxReport1.ShowPreparedReport;
end;
