阻止特定键盘的击键 [英] Block keystrokes from a specific keyboard

问题描述

我想阻止来自特定键盘的所有击键（由其HID /名称标识，所以我猜它是低级的东西）在它们到达重点应用程序之前就被阻止。但是我仍在使用此禁用的键盘（正在击键）。我想我需要一个应用程序的挂钩，但是我不知道该怎么做。也许您可以给我一些有用的链接？

I would like to block all keystrokes that are coming from a specific keyboard (identified by its HID/Name, so its low level stuff I guess) before they reach the focused application. But I'm still using this disabled keyboard (I'm getting the keystrokes). I think I need an application's hook but I don't know how to do that. Maybe you can give me some useful link?

问候，

编辑：

我认为我需要一个低级钩子，因为关于用户空间，.net框架中没有通用钩子（我的意思是钩住所有现有的窗口和线程）。
此外，我使用RAWINPUT从键盘获取键入的击键。因此，如果我制作了一个钩子来阻止来自特定设备的击键，那么钩子是否也可以阻止RAWINPUT？

I think I need a low-level hook, because general hook (I mean hook all the existing window & threads) aren't available in the .net framework, concerning the user-space. Moreover, I use RAWINPUT to get typed keystrokes from the keyboard. So if I make a hook to block keystroke from a specific device, could the hook block the RAWINPUT as well?

推荐答案

一个应用程序可以通过获取原始输入数据。但是，应用程序需要处理WM_INPUT而不是WM_CHAR，WM_MOUSEMOVE或WM_APPCOMMAND。

An application can distinguish the source of the input by getting raw input data. However the application needs to handle WM_INPUT instead of WM_CHAR, WM_MOUSEMOVE, or WM_APPCOMMAND.
