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
问题描述
我想知道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吗？
注意：我只对用Delphi和/或C ++编写的API感兴趣。
编辑：我的目标平台是Windows XP +
最后编辑：感谢大家的帮助，我已经创建了一个带有帮助方法的单元（在Delphi中）翻译为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
使用此结构： SYSTEM_POWER_STATUS ，并检查 ACLineStatus 字段的值。
- ACLineStatus = 0 =>系统未使用交流电源>笔记本电脑+电池
- ACLineStatus = 1 =>系统正在使用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。我不是声称如果他们是可靠的。

编辑：
使用 GetSystemPowerStatus 以获取上述结构的值。
顺便说一下，其他领域的结构;也许你可以找到一些有用的模式，给你不同字段的值的一些组合，以帮助您可靠地检测应用程序是否正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
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.
