Network / Received Packets are blank

« on: January 05, 2011, 01:49:23 am »

Hello. This is probably a noob question, but I have a sender program and a receiver program that send or receive Packets through TCP Sockets. The code for each is as follows:

Send

Code: [Select]


#include <SFML/Network.hpp>
#include <iostream>
//////////////////////////////////////////////
// STICS - Simple Two-Way Internet Chat System
// Server Program - Version 0.3
// Uses the SFML network library
// By David Phillips (2010-2011)
//////////////////////////////////////////////
using namespace std;

int main()
{
    cout << "STICS - Simple Two-Way Internet Chat System" << endl << "By David Phillips (2010-2011)" << endl << endl;
    cout << "Enter the server port:" << endl;
    int ServerPort;
    cin >> ServerPort;
    cout << "Awaiting connection..." << endl;
    sf::SocketTCP Listener;
    if (!Listener.Listen(ServerPort))
    {
        cout << "Could not create socket" << endl;
        return 0;
    }
    sf::IPAddress ServerAddress;
    sf::SocketTCP ServerRec;
    if (Listener.Accept(ServerRec, &ServerAddress) != sf::Socket::Done)
    {
        cout << "Error with server connection." << endl;
        return 0;
    }
    cout << "Ready" << endl;
    sf::Packet Received;
    string RecTemp;
    //Receiving loop
    do
    {
        ServerRec.Receive(Received);
        Received >> RecTemp;
        cout << RecTemp << endl;
    } while (true);
}



Receiver

Code: [Select]


#include <SFML/Network.hpp>
#include <iostream>
//////////////////////////////////////////////
// STICS - Simple Two-Way Internet Chat System
// Client Program - Version 0.4
// Uses the SFML network library
// By David Phillips (2010-2011)
//////////////////////////////////////////////
using namespace std;

int main()
{
    cout << "STICS - Simple Two-Way Internet Chat System" << endl << "By David Phillips (2010-2011)" << endl << endl;
    char ServerIP[64];
    int ServerPort;
    cout << "Enter server IP:" << endl;
    cin >> ServerIP;
    cout << endl << "Enter server port:" << endl;
    cin >> ServerPort;
    sf::SocketTCP ServerSend;
    connect:
    cout << "Connecting to " << ServerIP << " on port " << ServerPort << "..." << endl;
    if (ServerSend.Connect(ServerPort, ServerIP) != sf::Socket::Done)
    {
        cout << "Connection timed out" << endl;
        goto connect;
    }
    sf::Packet ToSend;
    string SendTemp;
    cout << "Connection to " << ServerIP << " made. STICS is now ready to chat!" << endl;
    do
    {
        getline(cin,SendTemp);
        ToSend << SendTemp;
        ServerSend.Send(ToSend);
    } while (true);
}


(Sorry for the inefficient coding, I'm just starting C++ and using the SFML Libraries)

When I send something to the receiver, there is just a blank line put on the console window for the Receiver - the packet's empty!!

Could I please get some help on this??

Thanks a lot!!!
