如何在收到WM_POWERBROADCAST消息时暂停Hibernate或Sleep？ [英] How to suspend Hibernate or Sleep when receiving the WM_POWERBROADCAST message?

问题描述

您好，我需要我的软件在运行时暂停休眠或睡眠状态。我做了一些测试，发现它在更改状态之前收到WM_POWERBROADCAST消息。我试图返回FALSE并返回  BROADCAST_QUERY_DENY
并且都不起作用？有任何想法吗？谢谢

Hello, I need my software to suspend Hibernation or Sleep while running. I did some tests and discovered that it is receiving a WM_POWERBROADCAST message before it changes states. I tried to return FALSE and also return BROADCAST_QUERY_DENY and neither work? Any Ideas? Thank you

推荐答案

在Vista和更新版本上，您应该使用SetThreadExecutionState来防止计算机进入休眠状态。

On Vista and newer you should use SetThreadExecutionState to prevent the computer from going to sleep.
