今天要查找如何获取系统从睡眠、休眠状态下唤醒的消息，写了个MFC对话框的程序，贴出部分核心代码：

//唤醒消息捕获
LRESULT CSystemResumedMessageDlg::WindowProc(UINT message, WPARAM wParam, LPARAM lParam)
{
    // TODO: 在此添加专用代码和/或调用基类
    if ((message == WM_POWERBROADCAST) && (wParam == PBT_APMRESUMEAUTOMATIC))
    {
        ShowSystemResumedTips();//捕获唤醒消息后的提示操作
    }
    return CDialog::WindowProc(message, wParam, lParam);
}

唤醒消息捕获参考了：http://bbs.csdn.net/topics/320261685

之前写过一个实现系统关机、重启、睡眠、休眠的实现，一并贴出代码：

/*
MySystemShutdown
功能：实现系统关机、重启
参数：
dwShutDownFlag：EWX_SHUTDOWN 关机 EWX_REBOOT 重启
bForce：强制执行
返回值：成功返回TRUE，否则返回FALSE
*/
BOOL MySystemShutdown(DWORD dwShutDownFlag = EWX_SHUTDOWN,BOOL bForce = FALSE)
{
    HANDLE hToken;
    TOKEN_PRIVILEGES tkp;
    // Get a token for this process.

    if (!OpenProcessToken(GetCurrentProcess(),
        TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken))
        return( FALSE );

    // Get the LUID for the shutdown privilege.

    LookupPrivilegeValue(NULL, SE_SHUTDOWN_NAME,
        &tkp.Privileges[0].Luid);

    tkp.PrivilegeCount = 1;  // one privilege to set
    tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;

    // Get the shutdown privilege for this process.

    AdjustTokenPrivileges(hToken, FALSE, &tkp, 0,
        (PTOKEN_PRIVILEGES)NULL, 0);

    if (GetLastError() != ERROR_SUCCESS)
        return FALSE;

    if (bForce)
    {
        dwShutDownFlag |= EWX_FORCE;//强制终止进程。当此标志设置，Windows不会发送消息WM_QUERYENDSESSION和WM_ENDSESSION的消息给目前在系统中运行的程序。这可能会导致应用程序丢失数据。
    }
    if (!ExitWindowsEx(dwShutDownFlag,
        SHTDN_REASON_MAJOR_OPERATINGSYSTEM |
        SHTDN_REASON_MINOR_UPGRADE |
        SHTDN_REASON_FLAG_PLANNED))
        return FALSE;

    return TRUE;
}

/*
MySystemSleep
功能：实现系统休眠、睡眠功能
参数：
bHibernate：TRUE休眠 FALSE睡眠
返回值：成功返回TRUE，否则返回FALSE
*/
BOOL MySystemSleep(BOOL bHibernate = TRUE)//
{
    HMODULE hModule = NULL;
    BOOL bRet = FALSE;
    //      BOOLEAN WINAPI SetSuspendState(
    //          __in          BOOLEAN Hibernate,
    //          __in          BOOLEAN ForceCritical,
    //          __in          BOOLEAN DisableWakeEvent
    //          );
    typedef BOOL (WINAPI *PSetSuspendState)(BOOL Hibernate,
        BOOL ForceCritical,
        BOOL DisableWakeEvent);
    hModule = LoadLibrary(_T("PowrProf.dll"));
    if (hModule)
    {
        PSetSuspendState pSetSuspendState = NULL;
        pSetSuspendState = (PSetSuspendState)::GetProcAddress(hModule,"SetSuspendState");//设置备份文件名函数指针
        if(pSetSuspendState != NULL)
        {
            bRet = pSetSuspendState(bHibernate,0,0);
        }
        FreeLibrary(hModule);
    }
    return bRet;
}
