检测应用程序是否在笔记本电脑上运行 [英] Detect if application is running on laptop

如何判断用户是否使用笔记本电脑

我试图找出应用程序是在笔记本电脑还是桌面上运行，有关如何实现这一点的任何想法？

注意：我只对使用Delphi和/或C ++编写的API感兴趣。

编辑：我的目标平台是Windows XP +，甚至Windows 7感谢您的帮助，我已经创建了一个带有助手方法的单元（在Delphi中），感觉自由翻译成C ++或其他语言和/或帮助扩展（或修复可能的缺陷）。
该单位可以在这里找到 http：//www.delphigeist .com / 2011/02 / laptop-specific-functions.html

解决方案

使用此结构体： SYSTEM_POWER_STATUS ，并检查 ACLineStatus 字段的值。

• ACLineStatus = 0 =>系统不使用交流电源>笔记本电脑电池


• ACLineStatus = 1 =>系统使用AC电源=>笔记本电脑+ AC


• ACLineStatus = 255 =>交流电源状态未知=>桌面

免责声明：尝试尝试这些。我不是声称他们是否可靠。但是他们几乎正确。

使用 GetSystemPowerStatus 以获得上述结构的价值。

顺便说一句，你也可以试验其他领域的结构;也许你可以找到一些有用的模式，给你不同领域的值的一些组合，以帮助你可靠地检测应用程序是否在笔记本电脑上运行。

How can I tell if a user is using a laptop

I'm trying to find out if the application is running on a laptop or on a desktop, any ideas on how to achieve this?

Note: I'm interested only in API's written in Delphi and/or C++.

EDIT: my target platform is Windows XP+, even Windows 7 only is OK.

LAST EDIT: thank you all for your help, I have created a unit with helper methods(In Delphi) feel free to translate to C++ or other languages and/or help extending(or fixing possible flaws). The unit can be found here http://www.delphigeist.com/2011/02/laptop-specific-functions.html

解决方案

Use this struct : SYSTEM_POWER_STATUS, and check the value of ACLineStatus field.

• ACLineStatus = 0 => The system is not using AC power > Laptop + battery
• ACLineStatus = 1 => The system is using AC power => Laptop + AC
• ACLineStatus = 255 => AC power status is unknown => Desktop

Disclaimer : Try experimenting with these. I'm not claiming if they're reliable. But they're almost correct.

EDIT:

Use GetSystemPowerStatus to get the value of the above mentioned structure.

By the way, you can also experiment with the other fields of the structure; maybe you can find some useful pattern, giving you some combination of values of different fields to help you reliably detect if application is running on laptop or not.
