如何以编程方式检测从屏幕消隐返回 [英] How do I programmatically detect returning from screen blanking
问题描述
我想在我的程序中检测屏幕空白是否关闭。
我尝试过：
我正在使用C ++，我的目标平台是Windows 7.
我在WinAPI编程方面有相当多的经验。
我想在我的程序中检测屏幕空白是否关闭。
这不是*屏幕保护程序，而是实际屏幕消隐操作本身。
（即，在我当前的机器上，我将屏幕保护程序设置为无，并将关闭显示屏设置为15分钟。这是打开显示屏，我想检测一下。）。
任何人都可以给我一些关于要查找的消息或事件的建议，以处理这个任务吗？
好的，我找到了一个适用于Windows 7 64位的解决方案。
我对WM_SYSCOLORCHANGE采取行动......这可能会略微过度杀死，但是因为我是尝试更新桌面图标颜色得到重置，这看起来工作得很好...
我有一个免费软件（32位）应用程序利用这种技术恢复桌面图标颜色改变了（我希望）。

I would like to detect, in my program, when screen blank is turned off.
What I have tried:
I'm using C++, and my target platform is Windows 7.
I have a fair amount of experience in WinAPI programming.
I would like to detect, in my program, when screen blank is turned off.
This is *not* the screen saver, but the actual screen blanking operation itself.
(i.e., on my current machine, I have screensaver set to None, and "Turn off the display" set to 15 minutes. It is the "Turn on the display" that I wish to detect.).
Can anyone give me advice on what message or event to look for, to handle this task?
Okay, I found a solution that works with Windows 7 64bit.
I act on WM_SYSCOLORCHANGE ... This possibly is slightly over-kill, but since I'm trying to update the desktop icon colors whenever they get reset, this appears to work quite nicely...
I have a freeware (32-bit) application which utilizes this technique to restore desktop icon color whenever it is changed (I hope).
Application is available here:
