关于idhttp,大家帮我看看

Question

我用idhttp下载文件，做了个button里面加了个idhttp.disconnect，一开始按下按钮总报错，说是not connected，后来有时又不报错了。我只想拦截这个错误，应该怎么拦截？它的编号是多少？还有连接超时的编号是10060，那用idhttp.get一个错误网址，报出的11004是什么错误呢？请指教，谢谢

procedure TForm1.Button2Click(Sender: TObject);
begin
idhttp1.DisconnectSocket;
end;procedure TForm1.Button1Click(Sender: TObject);
var
DownLoadFile:TFileStream;
a:string;
begin
DownLoadFile:=TFileStream.Create('c:\aa.rar',fmCreate);
a:='http://download.512j.com/soft/FlashMX2004-sc.zip';
try
  IdHTTP1.Get(a,DownLoadFile);
except
  showmessage('连接错误');
end;
 DownLoadFile.Free;
end;procedure TForm1.IdHTTP1WorkBegin(Sender: TObject; AWorkMode: TWorkMode;
  const AWorkCountMax: Integer);
begin
  progressbar1.Position:=1;
  progressbar1.Max:=aworkcountmax;
end;procedure TForm1.IdHTTP1WorkEnd(Sender: TObject; AWorkMode: TWorkMode);
begin
  progressbar1.Position:=progressbar1.Max;
end;procedure TForm1.IdHTTP1Work(Sender: TObject; AWorkMode: TWorkMode;
  const AWorkCount: Integer);
begin
  progressbar1.Position:=aworkcount;
end;拦截不了not connected的异常
