Hi guys, this is what i have been doing for the past couple of hours.

Run your server and just double click announce.exe. It will announce to masterlist.

Just got an interest on how vcmp announce is working.

announce.cpp

    char server_port[6] = "8192";
    if (argc == 2)
    {
        if (strlen(argv[1]) < 4)ZeroMemory(server_port, 6);
        memcpy(server_port, argv[1], strlen(argv[1]));
    }
    const char* PORT = "80";
   
    const char* IP_ADDR = "master.vc-mp.org";

    WSADATA wsaData;
    SOCKET ConnectSocket = INVALID_SOCKET;
    struct addrinfo* result = NULL,
        * ptr = NULL,
        hints;
    char recvbuf[DEFAULT_BUFLEN];
    int iResult;
    int recvbuflen = DEFAULT_BUFLEN;
    // Initialize Winsock
    iResult = WSAStartup(MAKEWORD(2, 2), &wsaData);
    if (iResult != 0) {
        printf("WSAStartup failed with error: %d\n", iResult);
        return 1;
    }

    ZeroMemory(&hints, sizeof(hints));
    hints.ai_family = AF_UNSPEC;
    hints.ai_socktype = SOCK_STREAM;
    //hints.ai_protocol = IPPROTO_UDP;

    // Resolve the server address and port
    iResult = getaddrinfo(IP_ADDR, PORT, &hints, &result);
    if (iResult != 0) {
        printf("getaddrinfo failed with error: %d\n", iResult);
        WSACleanup();
        return 1;
    }

            WSACleanup();
            return 1;
        }

        // Connect to server.
        iResult = connect(ConnectSocket, ptr->ai_addr, (int)ptr->ai_addrlen);
        if (iResult == SOCKET_ERROR) {
            closesocket(ConnectSocket);
            ConnectSocket = INVALID_SOCKET;
            continue;
        }
        break;
    }

    freeaddrinfo(result);

    if (ConnectSocket == INVALID_SOCKET) {
        printf("Unable to connect to server!\n");
        WSACleanup();

This is mainly made to call from other programs. You have to call regularly. samp calls their announce every 5 minutes. I think VCMP will retain server in masterlist for 15 minutes or so.

The default port is 8192. If there is a change in port, open Command Prompt, go to the directory where this exe lies and type
announce 8194
