如何确保Windows 2008 R2将SERVICE_CONTROL_PRESHUTDOWN控制通知传递给服务?

我正在使用普通c++和windows API编写一个服务，并希望它能够接收windows 2008 R2中可用的PRESHUTDOWN通知。

http://msdn.microsoft.com/en-us/library/windows/desktop/ms685996 (v = vs.85) . aspx

我希望这个服务处理预关机事件，并防止机器在任意时间内完成关机。

My ServiceMain循环，每5秒注销一条消息。

我将dwControlsAccepted设置为:

SERVICE_ACCEPT_STOP | SERVICE_ACCEPT_PRESHUTDOWN

我在我的ServiceControl回调中收到SERVICE_CONTROL_STOP通知。

如果我运行我的服务，并调用

sc query "MyService"

它说:

(STOPPABLE, NOT_PAUSABLE, ACCEPTS_PRESHUTDOWN)

在我收到任何服务控制通知之前，我就会在日志文件中写入一个条目。

当我关机时，windows会在屏幕上用白色的大字显示"正在停止我的服务"，并等待一会儿，然后完成关机。

主循环继续写入日志文件。日志文件不包含任何服务控制尝试的引用。

然后windows放弃关闭我的服务，直接杀死它。

现在，如果我做完全相同的事情，但注册SHUTDOWN而不是PRESHUTDOWN，我看到日志文件中我期望看到的所有通知(尽管不能延长关机期，因为我们不能从关机通知中做到这一点)。

代码的唯一变化是删除了设置状态调用中的三个字母"PRE"。

我甚至没有达到我可以开始增加dwCheckPoint的点- windows子系统没有通知我。

Windows知道我正在寻找预关机消息，如"sc查询"所证明的，是否有什么可以阻止它接收预关机消息?

报告状态时(SCM报告服务已启动，非常愉快)

VOID ServiceReportStatus (DWORD dwCurrentState, DWORD dwWin32ExitCode, DWORD dwWaitHint)
{
    // Fill in the SERVICE_STATUS structure.
    g_serviceStatus.dwCurrentState = dwCurrentState;
    g_serviceStatus.dwWin32ExitCode = dwWin32ExitCode;
    g_serviceStatus.dwWaitHint = dwWaitHint;
    switch(dwCurrentState)
    {
    case SERVICE_START_PENDING:
    case SERVICE_STOP_PENDING:
    case SERVICE_CONTINUE_PENDING:
    case SERVICE_PAUSE_PENDING:
        g_serviceStatus.dwControlsAccepted = 0;
        break;
    default:
        g_serviceStatus.dwControlsAccepted = SERVICE_ACCEPT_STOP | SERVICE_ACCEPT_PRESHUTDOWN;
    }
    // Report the status of the service to the SCM.
    SetServiceStatus (g_serviceStatusHandle, &g_serviceStatus);
}

当我收到消息时:

VOID WINAPI ServiceCtrlHandler (DWORD dwCtrl)
{
    LOG(eDeveloper10, L"ServiceCtrlHandler", L"Decoding SvcControl %dn", dwCtrl);
   switch(dwCtrl) 
   {
      case SERVICE_CONTROL_PRESHUTDOWN:
          {
             LOG(eDeveloper10, L"ServiceCtrlHandler", L"Received SERVICE_CONTROL_PRESHUTDOWNn");
             ServiceReportStatus(SERVICE_STOP_PENDING, NO_ERROR, 10000);
             // Signal the service to stop.
             SetEvent(g_serviceStopEvent);
             break;
          }
    }
}

它做了更多的事情，但在这个例子中没有什么用处，因为我甚至没有看到日志(除非我注册为SHUTDOWN)。

ServiceCtrlHandler总是很快返回，我没有在这里阻塞，我没有进入这里的预关闭处理程序。注册PRESHUTDOWN和SHUTDOWN也没有帮助。我在两台Windows 2008R2机器上进行了测试，一台是虚拟机，一台是物理机，结果是一样的。服务被编译为x64二进制文件。

任何想法?

一些示例日志，这个日志是当我请求被通知关机时:

请注意，在这种特殊情况下，阻塞服务关闭是正确的行为。

如果我注册PRESHUTDOWN，我从ServiceCtrlHandler根本得不到任何东西:

没有任何事件，直到windows放弃并杀死它。
