检测系统范围内的击键 [英] Detecting a keystroke system-wide

问题描述

我是C ++的新手，我正在尝试制作一个程序来自动执行某些任务。当我点击ctrl时，我想用函数调用生成一个新线程 - 但是我在查找如何获得ctrl - 检查时遇到了一些麻烦。我查看了GetKeyState
，但似乎只看了一个键。我不知道如何继续这一点，任何帮助将不胜感激

Hi, I'm pretty new to C++ and am trying to make a program to automate some tasks. I want to spawn a new thread with a function call when I hit ctrl - but I am having some trouble figuring out how to get the ctrl - check. I looked at GetKeyState but it seems to only look at a single key. I'm not sure how to proceed with this and any help would be greatly appreciated

推荐答案

尝试此序列：

   RegisterHotKey（hwnd，1，
MOD_CONTROL |
MOD_NOREPEAT ，
VK_SUBTRACT ）;

   RegisterHotKey（hwnd，2，
MOD_CONTROL |
MOD_NOREPEAT ，
VK_OEM_MINUS ）;

 

< span lang ="EN-GB"style ="margin：0px"> 其中
hwnd 是 HWND 你的窗口。该窗口将收到
WM_HOTKEY 通知。

where hwnd is HWND of your window. The window will receive the WM_HOTKEY notification.

如果您没有窗口，请参阅
hwnd NULL ：
< span style ="color：＃0563c1"> https://docs.microsoft.com/en-us/windows/desktop/api/winuser/nf-winuser-registerhotkey 。

If you do not have a window, see the example where hwnd is NULL: https://docs.microsoft.com/en-us/windows/desktop/api/winuser/nf-winuser-registerhotkey.
