关于驱动启动的问题

前段时间买了《从汇编语言到WINDOWS内核编程》这本书，看了大部分了，一直有个问题想问下，一个编译好的sys文件，如何用自己的程序装载起来。查了资料可以用 OpenSCManager,CreateService, StartService,这3个函数启动驱动，但是自己一直没实现，希望老鸟给点提示。。。

bool LoadDriver(LPCTSTR lpszDriverName, LPCTSTR lpszDriverPath)
{
    char szDriverFilePath[MAX_PATH];
    GetFullPathName(lpszDriverPath, MAX_PATH, szDriverFilePath, NULL);

    bool bRet = true;
    DWORD dwReturn;
    SC_HANDLE hServiceMgr = NULL;
    SC_HANDLE hServiceSys = NULL;

    // 打开服务管理器
    hServiceMgr = OpenSCManager(NULL, NULL, SC_MANAGER_ALL_ACCESS);
    if (!hServiceMgr)
    {
        printf("OpenSCManager() Error!\n");
        bRet = false;
        goto END;
    }

    // 创建驱动服务
    hServiceSys = CreateService(hServiceMgr,
                                  lpszDriverName,            // 驱动服务名
                                  lpszDriverName,            // 驱动服务显示名
                                  SERVICE_ALL_ACCESS,
                                  SERVICE_KERNEL_DRIVER,    // 内核驱动
                                  SERVICE_DEMAND_START,        // 手动启动
                                  SERVICE_ERROR_IGNORE,        // 忽略错误
                                  szDriverFilePath,            // 服务文件路径
                                  NULL,
                                  NULL,
                                  NULL,
                                  NULL,
                                  NULL);
    if (!hServiceSys)
    {
        dwReturn = GetLastError();
        if ((dwReturn != ERROR_IO_PENDING) && (dwReturn != ERROR_SERVICE_EXISTS))
        {
            // 服务创建失败，未知错误
            printf("CreateService() Error : %d!\n", dwReturn);
            bRet = false;
            goto END;
        }
        
        // 服务已经存在，只需打开
        hServiceSys = OpenService(hServiceMgr, lpszDriverName, SERVICE_ALL_ACCESS);
        if (!hServiceSys)
        {

            bRet = false;
            goto END;
        }
    }

            bRet = false;
            goto END;
        }
        else
        {
            if (dwReturn == ERROR_IO_PENDING)
            {

实在 太谢谢楼上的人了，
