[求教]如何获取硬盘序列号? 我看到一段程序,是获取硬盘序列号的,但在我的机器上不能返回序列号值, getVolumnInformation 返回保龄球为 False. 这到底是怎么回呈?请大侠指教。 我的硬盘是是希捷40G的, Win98SE + Delphi7. 盼复谢了。 procedure TForm1.Button1Click(Sender: TObject); var SerialNum : pdword; a, b : dword; Buffer : array [0..255] of char; begin if GetVolumeInformation('c:\', Buffer, SizeOf(Buffer), SerialNum, a, b, nil, 0) then Label1.Caption := IntToStr(SerialNum^); ; end;
