如何通过Windows API访问系统规格? [英] How do I get access to system specs via the Windows API?

问题描述

如何从Windows API访问有关计算机规格的信息?我是否需要在注册表中查找(如果有的话)?我希望我的程序可以访问的一些关键信息包括图形卡型号和规格，受支持的OpenGL和DirectX版本，受支持的屏幕分辨率，CPU信息，总/可用磁盘空间以及RAM信息等.在Win32中，我可以使用哪些类型的有效方法来访问此信息?

How do I access information about the computer's specifications from the Windows API? Do I need to look in the registry, if so where? Some key information I would like my programs to have access to are the graphics card model and specs, supported versions of OpenGL and DirectX, supported screen resolutions, CPU information, total/available disk space, and RAM information, among others. What types of efficient methods can I use to access this information in Win32?

非常感谢您的建议！

推荐答案

所有这些信息以及更多信息都通过WMI(Windows Management Instrumentation)在Windows中公开.外观此处查看代码示例.标准Win32 WMI类的集合是在此处记录.

All of this info, and much more, is exposed in Windows through WMI (Windows Management Instrumentation). A good starting point to discover queries and try them out on your machine is the WMI Code Creator tool. It generates code too but not C++ code. That's fairly ugly but boilerplate, look here for code samples. The set of standard Win32 WMI classes is documented here.
