How get response from Habbo Emulator?

[Kylon]

Hi guys.
currently I'm coding a small client and sooooooooooooo. I must connect with my local server (PlusEMU), but when I try to connect (everything is working fine), I don't get any response from the server like a string or what ever.

What did I wrong?

        Socket client = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);        IPEndPoint endPoint;


        private byte[] _recieveBuffer = new byte[8142];


        public SocketHandler()
        {
            Console.WriteLine("Trying to connect...");
            try
            {
                endPoint = new IPEndPoint(IPAddress.Parse("127.0.0.1"), 30000);
                client.Connect(endPoint);


                if(client.Connected)
                {
                    Console.WriteLine("Connected!");
                    byte[] data = Encoding.ASCII.GetBytes("test");
                    SendData(data);
                    client.BeginReceive(_recieveBuffer, 0, _recieveBuffer.Length, SocketFlags.None, new AsyncCallback(ReceiveCallback), null);
                }
            }
            catch(Exception exe)
            {
                Console.WriteLine("Can't connect\n" + exe.ToString());
            }
        }


        private void ReceiveCallback(IAsyncResult AR)
        {
            int recieved = client.EndReceive(AR);


            if (recieved <= 0)
                return;


            byte[] recData = new byte[recieved];
            Buffer.BlockCopy(_recieveBuffer, 0, recData, 0, recieved);




            client.BeginReceive(_recieveBuffer, 0, _recieveBuffer.Length, SocketFlags.None, new AsyncCallback(ReceiveCallback), null);
        }


        private void SendData(byte[] data)
        {
            SocketAsyncEventArgs socketAsyncData = new SocketAsyncEventArgs();
            socketAsyncData.SetBuffer(data, 0, data.Length);
            client.SendAsync(socketAsyncData);
        }

It's because the packet structure doesn't match. You need to have a matching packet structure & packet id in order to receive any response. Also put a try & catch block arround EndReceive & disconnect your socket if your received data <= 0 not just return.
