This is my client code:

(My server is very similar at the moment but I will upload it below this one just in case somebody wants to run it)

#include <SFML/Graphics.hpp>
#include <SFML/Network.hpp>
#include <thread>

int main()

 sf::RenderWindow main_win(sf::VideoMode(800, 800), "Chatcy!");
 main_win.setPosition(sf::Vector2i(sf::VideoMode::getDesktopMode().width/2 -400, sf::VideoMode::getDesktopMode().height/2 -400));
 main_win.setVerticalSyncEnabled(true);

 //chatcy logo
 sf::Texture chatcy;
 chatcy.loadFromFile("image_chatcy.png");
 sf::Sprite logo;
 logo.setTexture(chatcy); //200x800

 //font
 sf::Font font;
 font.loadFromFile("FreeSerif.ttf");

 //name
 sf::String name("Client");
 name += ": ";

 //text input area and background
 sf::RectangleShape in_background(sf::Vector2f(800, 100));
 in_background.setFillColor(sf::Color::Black);
 in_background.setPosition(0, 700);

 sf::Text inText;
 inText.setFont(font);
 inText.setPosition(0, 700);

 sf::String input(name);
 inText.setString(input);

 //text output area
 sf::Text outText;
 outText.setFont(font);
 outText.setCharacterSize(24);
 outText.setPosition(0, 200);
 sf::String output;

 //networking
 sf::TcpSocket socket;
 sf::Socket::Status status = socket.connect("31.216.109.207", 55552);
 if(status != sf::Socket::Done)
 
 outText.setString("nCannot connect to the server!n");
 return -1;
 
 else
 outText.setString("nYou have been connected to the server!n");

 socket.setBlocking(false);

 //Packet for incoming msg
 sf::Packet in_packet;

 switch (event.type)

 socket.send(out_packet);

 input.clear();
 input += name;

 break;
 case sf::Event::MouseWheelScrolled: 
 //-7 for speed and to go the same way with scroll (-)

 break;

 if(socket.getRemoteAddress() == sf::IpAddress::None)
 
 output += "nConnection has been terminated. Goodbye!n";
 outText.setString(output);
 

 main_win.clear(sf::Color::Black);
 main_win.draw(outText);
 main_win.draw(in_background);
 main_win.draw(logo);
 main_win.draw(inText);
 main_win.display();
 

I need a way to put this mess in an order. I would like to find an object oriented way to make the client more efficient and then I will use the classes to make an actually server! (I will post another question for the server I guess :P )

Server:

#include <SFML/Graphics.hpp>
#include <SFML/Network.hpp>
#include <SFML/Audio.hpp>
#include <iostream>

int main()

 main_win.setVerticalSyncEnabled(true);

 //chatcy logo
 sf::Texture chatcy;
 chatcy.loadFromFile("image_chatcy.png");
 sf::Sprite logo;
 logo.setTexture(chatcy); //200x800

 //font
 sf::Font font;
 font.loadFromFile("FreeSerif.ttf");

 //name
 sf::String name("George");
 name += ": ";

 //text input area and background
 sf::RectangleShape in_background(sf::Vector2f(800, 100));
 in_background.setFillColor(sf::Color::Black);

You may ignore the sound or put your own if you are going to run it. The image is a cosmetic logo. Also note that background is used so that text behind it is not visible.
