我写一段，你将东西套进去就可以了，这里原来写的是定时服务，用的是boost::asio库，当然最好看一看boost::asio相关介绍。

#include <iostream>
#include <fstream>
#include <boost/asio.hpp>
#include <boost/bind.hpp>
#include <boost/function.hpp>
#include <boost/date_time/posix_time/posix_time.hpp>
#ifdef _WIN32
#include <windows.h>
#endif

class printer
{
public:
    printer(boost::asio::io_service &io)
    {
    ........
    }

    ~printer()
    {
    }
   ......
};



#ifdef _WIN32
boost::function0<void> console_ctrl_function;
SERVICE_STATUS_HANDLE g_ssh = NULL;
DWORD g_dwStatus = SERVICE_STOPPED;
int g_exitcode;

BOOL WINAPI console_ctrl_handler(DWORD ctrl_type)
{
    switch (ctrl_type)
    {
        case CTRL_C_EVENT:
        case CTRL_BREAK_EVENT:
        case CTRL_CLOSE_EVENT:
        case CTRL_SHUTDOWN_EVENT:
            console_ctrl_function();
            return TRUE;
        default:
            return FALSE;
    }
}

void SetStatus(DWORD dwStatus)
{
    SERVICE_STATUS ss = {
        SERVICE_WIN32_OWN_PROCESS,
        SERVICE_STOPPED,
        SERVICE_ACCEPT_STOP,
        NO_ERROR,
        0,
        1,
        5000};

    ss.dwCurrentState = dwStatus;
    SetServiceStatus(g_ssh, &ss);
    g_dwStatus = dwStatus;
}


VOID WINAPI Handler(DWORD dwCtl)
{
    switch (dwCtl)
    {
        case SERVICE_CONTROL_STOP:
            console_ctrl_function();
            break;
        default:
            SetStatus(g_dwStatus);
    }
}

VOID WINAPI ServiceMain(DWORD dwArgc, LPTSTR *lpszArgv)
{
    g_ssh = RegisterServiceCtrlHandler(lpszArgv[0], Handler);

    SetStatus(SERVICE_START_PENDING);
    try
    {
        boost::asio::io_service io;
        printer p(io);
        console_ctrl_function = boost::bind(&boost::asio::io_service::stop, &io);
        SetStatus(SERVICE_RUNNING);
        io.run();
        g_exitcode = EXIT_SUCCESS;
    }
    catch (std::exception &e)
    {
        std::cerr << "[EXCEPTION]\t" << e.what() << std::endl;
        g_exitcode = EXIT_FAILURE;
    }
    catch (const char *e)
    {
        std::cerr << "[EXCEPTION]\t" << e << std::endl;
        g_exitcode = EXIT_FAILURE;
    }
    SetStatus(SERVICE_STOPPED);
}

int main(int argc, char **argv)
{
    SERVICE_TABLE_ENTRY arSvc[] =
    {
        {L"ChinuxTeam TestServ v1.0", ServiceMain},
        {NULL, NULL}
    };
    if (!StartServiceCtrlDispatcher(arSvc))
    {
        std::cerr << "Start Service Error" << std::endl;
        return EXIT_FAILURE;
    }
    return g_exitcode;
}

qt solution有关于service的,跟qt整合得好一点，不过如果只是想实现服务，不是要搞什么跨平台啊，库啊之类的，在win上直接参考msdn吧，搜索也可以给出一大堆的代码
