请问这样用idudpclient发送流对吗，怎样的写idudpserver接收函数（onudpread）才能接受回十六进制数呢？(100分)

datastream.WriteBuffer(data[0],4);
IdUDPClient1.SendBuffer(DataStream,DataStream.Size);
showmessage('baichi');

这样回来是不是可以？
procedure TForm1.IdUDPServer1UDPRead(Sender:TObject; AData:TStream;
ABinding:TIdSocketHandle);
var
DataStream:TMemoryStream;
begin
DataStream:=TMemoryStream.Create;
try
DataStream.CopyFrom(AData,AData.Size);
finally
DataStream.Free;
end;
end;

抱歉，前段时间上不了网，今天试了一下，我还想问问，如何用showmessage（‘’）把接收的数据转换成字符读出来，我做了，估计做法不行，请楼上继续指教，可以不 》？

procedure TForm1.IdUDPServer1UDPRead(Sender:TObject; AData:TStream;
ABinding:TIdSocketHandle);
var
LStr:String;
begin
LStr:=StrPas(PChar(AData.Memory));
Showmessage(LStr);
end;

AData.Memory在delphi7中通不过编译，adata有Memory的属性》？是否要转化为TCustomMemoryStream ？好像不行呀，晕。
