W8服务的已连接待机通知 [英] Connected standby notification for a W8 Service

问题描述

我有一个服务，开发在C + +运行在Windows 8（和8.1）。我如何知道系统已进入连接待机？

I have a service, developed in C++ running on Windows 8 (and 8.1). How can I get to know that the system has entered Connected Standby?

由于这是一个服务，它没有窗口，我应该使用 PowerRegisterSuspendResumeNotification ，但它似乎不工作。有人知道我如何获得这样的通知吗？

Since this is a service, it does not have a window, I should be using PowerRegisterSuspendResumeNotification, but it does not seem to be working. Does anyone know how I can get such a notification?

推荐答案

我已联系Microsoft的技术支持。这是他们的答案：

I have contacted Microsoft's technical support. This is their answer:

没有直接通知ConnectedStandby进入/退出，但你可以使用监视器开/ ConnectedStandby与AOAC系统上的屏幕关闭同义（但不是在传统系统上，可以通过使用CallNtPowerInformation获取SystemPowerCapabilities并查看SYSTEM_POWER_CAPABILITIES结构的AoAc值来获得AOAC功能）。

There are no direct notifications for ConnectedStandby enter/exit, but you can just use the monitor on/off notifications since ConnectedStandby is synonymous with screen off on an AOAC capable system (but is not on a legacy system, AOAC capability can be had by getting SystemPowerCapabilities using CallNtPowerInformation and looking at the AoAc value of the SYSTEM_POWER_CAPABILITIES struct).

要获得监视器的开/关通知，您可以使用RegisterPowerSettingNotification并使用GUID_MONITOR_POWER_ON电源设置GUID。

To get monitor on/off notifications you can use RegisterPowerSettingNotification and use the GUID_MONITOR_POWER_ON power setting GUID.

像只有一个解决方法，通过监听屏幕开/关事件。

Looks like there is only a workaround for this by listening to screen on/off events.
