WinAPI:如何获取大写锁定状态? [英] WinAPI: How to get the caps lock state?

问题描述

如何打开或关闭Caps Lock? 我尝试搜索它，但发现的只是如何切换或打开/关闭它，这与我要查找的内容完全相反.

How can get whether Caps Lock is on or off? I tried to search it but all I'm finding is how to toggle or turn it on/off which is exactly opposite of what I'm looking for.

我正试图在C ++和Delphi中做到这一点.
请帮助

I'm trying to do that in both C++ and Delphi.
Please help
