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

问题描述

如何获取 Caps Lock 是打开还是关闭?我试图搜索它，但我发现的只是如何切换或打开/关闭它，这与我正在寻找的完全相反.

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.

我正在尝试在 C++ 和 Delphi 中做到这一点.
请帮忙

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