hi

i have msdn tcp/ip sample :

#include "stdafx.h"

//int _tmain(int argc, _TCHAR* argv[])
//{
// return 0;
//}

#include "winsock2.h"

void main() {

    // Initialize Winsock.
    WSADATA wsaData;
    int iResult = WSAStartup( MAKEWORD(2,2), &wsaData );
    if ( iResult != NO_ERROR )
        printf("Error at WSAStartup()\n");

    // Create a socket.
    SOCKET m_socket;
    m_socket = socket( AF_INET, SOCK_STREAM, IPPROTO_TCP );

    if ( m_socket == INVALID_SOCKET ) {
        printf( "Error at socket(): %ld\n", WSAGetLastError() );
        WSACleanup();
        return;
    }

    // Connect to a server.
    sockaddr_in clientService;

    clientService.sin_family = AF_INET;
    clientService.sin_addr.s_addr = inet_addr( "127.0.0.1" );
    clientService.sin_port = htons( 27015 );

    if ( connect( m_socket, (SOCKADDR*) &clientService,
sizeof(clientService) ) == SOCKET_ERROR) {
        printf( "Failed to connect.\n" );
        WSACleanup();
        return;
    }

    // Send and receive data.
    int bytesSent;
    int bytesRecv = SOCKET_ERROR;
    char sendbuf[32] = "Client: Sending data.";
    char recvbuf[32] = "";

    bytesSent = send( m_socket, sendbuf, strlen(sendbuf), 0 );
    printf( "Bytes Sent: %ld\n", bytesSent );

    if ( bytesRecv == 0 ||
        (bytesRecv == SOCKET_ERROR &&
         WSAGetLastError()== WSAECONNRESET ))
    {
        bytesRecv = recv( m_socket, recvbuf, 32, 0 );
        if ( bytesRecv == -1 )
        {
            printf( "Connection Closed.\n");
            break;
        }
        if (bytesRecv < 0)
            return;
        printf( "Bytes Recv: %ld\n", bytesRecv );
    }

    WSACleanup();
    return;
}
