delphi的hibernate推送和检测 [英] delphi hibernate push and detect

问题描述

使用Delphi5。

我有一个从Windows启动开始的应用程序，我想关闭并启动它在Hibernate / Wake命令。

I have an app that starts with windows boot and I would like to Close and Start it on the Hibernate/Wake command.

我需要能够检测到它是否从Hibernate回来，所以我可以每次运行我的应用程序。我在注册表中有一个设置，用户可以选择每天只运行一次。

I need to be able to detect if it is coming back from an Hibernate so I can run my app each time. I have a setting in the Registry where the User can choose to run only once per day.

我猜测有一个Windows消息或注册表项，告诉机器它将从Hibernate进入并返回。

I am guessing there is a windows Message or Registry entry that tells the machine that it is going into and coming back from an Hibernate.

想法和建议？

感谢您的看法

推荐答案

您可以通过监听 WM_POWERBROADCAST
消息在您的应用程序。此消息将发送到所有正在运行的
应用程序，通知电源管理事件已发生。这个消息的wParam部分是您可以检查系统是否进入挂起状态（ PBT_APMSUSPEND ）或从一个恢复（ PBT_APMRESUMESUSPEND ）。

You could achieve such application behaviour by listening for the WM_POWERBROADCAST message in your application. This message is sent to all running applications notifying that a power-management event has occurred. wParam part of this message is where you can check if the system is entering a suspended state(PBT_APMSUSPEND) or recovering from one(PBT_APMRESUMESUSPEND).
