如何在系统重新启动时启动Windows服务停止事件？

问题描述：

我已经用VC++编写Windows Service来在系统重新启动时安装驱动器。现在，当我重新启动系统，在系统关机时，我想激发我的服务停止事件，但未被触发。如何在系统重新启动时启动Windows服务停止事件？

我已将Windows服务属性设置为自动，但不起作用。当我手动点击停止按钮停止事件被解雇。

任何帮助apprecaited。我的代码看起来像：

void WINAPI ServiceCtrlHandler(DWORD Opcode) 
{ 
    switch(Opcode) 
    { 
    case SERVICE_CONTROL_PAUSE: 
     m_ServiceStatus.dwCurrentState = SERVICE_PAUSED; 
     break; 
    case SERVICE_CONTROL_CONTINUE: 
     m_ServiceStatus.dwCurrentState = SERVICE_RUNNING; 
     break; 
    case SERVICE_CONTROL_STOP: 
     m_ServiceStatus.dwWin32ExitCode = 0; 
     m_ServiceStatus.dwCurrentState = SERVICE_STOPPED; 
     m_ServiceStatus.dwCheckPoint = 0; 
     m_ServiceStatus.dwWaitHint = 0; 

    Disconnect() ;// This method i want to get called on system shot down automatically. 

     SetServiceStatus (m_ServiceStatusHandle,&m_ServiceStatus); 
     bRunning=false; 
     break; 
    case SERVICE_CONTROL_INTERROGATE: 
     break; 
    } 
    return; 
}

答

这是相对直截了当的。通过向switch语句添加另一个case来处理当前回调处理函数中的SERVICE_CONTROL_SHUTDOWN。大概是这样的：

void WINAPI ServiceCtrlHandler(DWORD Opcode) 
{ 
    switch(Opcode) 
    { 
    case SERVICE_CONTROL_PAUSE: 
     m_ServiceStatus.dwCurrentState = SERVICE_PAUSED; 
     break; 
    case SERVICE_CONTROL_CONTINUE: 
     m_ServiceStatus.dwCurrentState = SERVICE_RUNNING; 
     break; 
    case SERVICE_CONTROL_STOP: 
     m_ServiceStatus.dwWin32ExitCode = 0; 
     m_ServiceStatus.dwCurrentState = SERVICE_STOPPED; 
     m_ServiceStatus.dwCheckPoint = 0; 
     m_ServiceStatus.dwWaitHint = 0; 

    Disconnect() ;// This method i want to get called on system shot down automatically. 

     SetServiceStatus (m_ServiceStatusHandle,&m_ServiceStatus); 
     bRunning=false; 
     break; 
    case SERVICE_CONTROL_INTERROGATE: 
     break; 

    case SERVICE_CONTROL_SHUTDOWN: 
     Disconnect(); 
     break; 
    } 
    return; 
}

OR：

注册与RegisterServiceCtrlHandler回调函数使用RegisterServiceCtrlHandlerEx代替。这种新的回调方法是首选。你的回调函数的签名需要匹配HandlerEx, see MSDN for more info。

DWORD WINAPI HandlerEx(
    __in DWORD dwControl, 
    __in DWORD dwEventType, 
    __in LPVOID lpEventData, 
    __in LPVOID lpContext 
);

添加其他情况下你的switch语句，无论是SERVICE_CONTROL_PRESHUTDOWN（不可用XP/Server 2003上）或SERVICE_CONTROL_SHUTDOWN，阅读有关处理上面引用的HandlerEx文档中这些通知的警告。
