UDP Socket verbindung?

[sirius]

Wie sieht denn deine Methode jetzt aus?

Edit1:
Ich habe mir das Protokoll zwar nicht angesehen, aber mit dem Programm:

Delphi-Quellcode:

unit TestUnit;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls, u_udpSocket;

type
  TForm1 = class(TForm)
    Button1: TButton;
    Memo1: TMemo;
    procedure Button1Click(Sender: TObject);
    procedure FormCreate(Sender: TObject);
  private
    { Private-Deklarationen }
    FSock:TUDP_Socket;
    procedure RecvSock(Sender:TObject);
  public
    { Public-Deklarationen }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.Button1Click(Sender: TObject);
var
  buffer: String;
begin
  buffer:=#$FE#$FD#$00#$10#$20#$30#$40#$FF#$FF#$FF#$01;
  Fsock.Send(buffer[1],length(buffer));
end;
procedure TForm1.RecvSock(Sender: TObject);
var buffer: array[0..8191] of byte;
    len:Integer;
    i,j:integer;
    s:string;
begin
  fillchar(buffer,8192,0);
  len:=FSock.recv(buffer[0],8192);
  memo1.Lines.BeginUpdate;
  try
    memo1.lines.add(inttostr(len));
    for j:=0 to len div 20 do
    begin
      s:='';
      for i:=0 to 19 do s:=s+' '+inttohex(buffer[j*20+i],2);
      memo1.lines.add(s);
    end;
  finally
    memo1.lines.EndUpdate;
  end;
end;

procedure TForm1.FormCreate(Sender: TObject);
begin
  Fsock:=TUDP_Socket.Create(self);
  FSock.onReceiving:=RecvSock;
  Fsock.RemoteHost := '69.12.76.145';
  Fsock.RemotePort := 29900;
  Fsock.SocketMode := smEvent;
  Fsock.Open;
end;

end.

bekomme ich diese Antwort:

Aber an deine Firewall hast du gedacht?
