• Double click on the "hello-ixwebsocket.cpp" file:

• Replace the "hello-ixwebsocket.cpp" file content with the following one:

#include <ixwebsocket/IXNetSystem.h>
#include <ixwebsocket/IXWebSocket.h>
#include <ixwebsocket/IXUserAgent.h>

#include <iostream>

// Our websocket object
ix::WebSocket webSocket;

int main()
{
    // Required on Windows
    ix::initNetSystem();

    std::string url("wss://testing-websockets-using-emscripten-sdl3-and-opengl-es-20.glitch.me");
    webSocket.setUrl(url);

    std::cout << "Connecting to " << url << "..." << std::endl;

    // Setup a callback to be fired (in a background thread, watch out for race conditions !)
    // when a message or an event (open, close, error) is received
    webSocket.setOnMessageCallback([](const ix::WebSocketMessagePtr& msg)
        {
            if (msg->type == ix::WebSocketMessageType::Message)
            {
                std::cout << "received message: " << msg->str << std::endl;
                std::cout << "> " << std::flush;
            }
            else if (msg->type == ix::WebSocketMessageType::Open)
            {
                std::cout << "Connection established" << std::endl;
                std::cout << "> " << std::flush;
            }
            else if (msg->type == ix::WebSocketMessageType::Error)
            {
                // Maybe SSL is not configured properly
                std::cout << "Connection error: " << msg->errorInfo.reason << std::endl;
                // std::cout << "> " << std::flush;
            }
        }
    );

    // Now that our callback is setup, we can start our background thread and receive messages
    webSocket.start();

    // Send a message to the server (default to TEXT mode)
    webSocket.send("hello world");

    getchar();
    return 0;
}
