simple announce
«  »
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.

Code: [Select]
#include <windows.h>
#include <winsock2.h>
#include <ws2tcpip.h>
#include <stdlib.h>
#include <stdio.h>
#include <math.h>
#include <thread>
// Need to link with Ws2_32.lib, Mswsock.lib, and Advapi32.lib
#pragma comment (lib, "Ws2_32.lib")
#pragma comment (lib, "Mswsock.lib")
#pragma comment (lib, "AdvApi32.lib")

#define DEFAULT_BUFLEN 10240

int __cdecl main(int argc, char** argv)
    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,
    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);
        return 1;

    // Attempt to connect to an address until one succeeds
    for (ptr = result; ptr != NULL; ptr = ptr->ai_next) {

        // Create a SOCKET for connecting to server
        ConnectSocket = socket(ptr->ai_family, ptr->ai_socktype,
        if (ConnectSocket == INVALID_SOCKET) {
            printf("socket failed with error: %ld\n", WSAGetLastError());
            return 1;

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


    if (ConnectSocket == INVALID_SOCKET) {
        printf("Unable to connect to server!\n");
        return 1;
    char buf[512];
    sprintf(buf,"POST /announce.php HTTP/1.1\r\n"
        "Host: master.vc-mp.org\r\n"
        "Connection: close\r\n"
        "User-Agent: VCMP/0.4\r\n"
        "VCMP-Version: 0.4\r\n"//VCMP->GetServerVersion();
        "Content-Type: application/x-www-form-urlencoded\r\n"
        "Content-Length: %d\r\n"//strlen of "PORT:8192"
    printf("%s\n", buf);
    // Send an initial buffer
    iResult = send(ConnectSocket, buf, strlen(buf), 0);
    if (iResult == SOCKET_ERROR) {
        printf("send failed with error: %d\n", WSAGetLastError());
        return 1;
    else printf("iResult is %d\n", iResult); int len = 5192;
    char reply[4096];
    iResult = 0;
    iResult = recv(ConnectSocket, reply, len, 0);
    if (iResult > 0)
        printf("iResult is %d\n",iResult);
        reply[iResult] = '\0';
        printf("reply is %s\n", reply);


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
