检测模拟键盘/鼠标输入

Detecting simulated keyboard/mouse input(检测模拟键盘/鼠标输入)

问题描述

有没有办法检测 Windows 上的模拟键盘/鼠标输入.例如，用户在他的键盘上输入一些东西，而不是 sendKeys/PostMessage/屏幕键盘.有没有办法区分这两者?

Is there a way to detect simulated keyboard/mouse input on Windows. For example, a user types something on his keyboard vs sendKeys/PostMessage/On-screen keyboard. Is there a way that I can distinguish between the two?

也许一个例子会有所帮助.我正在制作游戏并想区分真实输入与 WinAPI 合成键盘/鼠标消息.

Perhaps an example would help. I am making a game and want to distinguish between real input vs WinAPI synthesizing keyboard/mouse messages.

推荐答案

我可能错了，但屏幕键盘(和其他模拟用户输入的应用程序)很可能使用 SendInput API:

I might be wrong, but the on-screen keyboard (and other applications that simulate user input) most probably uses the SendInput API:

SendInput 在输入堆栈的底层运行.它只是键盘和鼠标驱动程序用来告诉窗口管理器用户生成输入的相同输入机制的后门.来源:http://blogs.msdn.com/b/oldnewthing/archive/2010/12/21/10107494.aspx

SendInput operates at the bottom level of the input stack. It is just a backdoor into the same input mechanism that the keyboard and mouse drivers use to tell the window manager that the user has generated input. Source: http://blogs.msdn.com/b/oldnewthing/archive/2010/12/21/10107494.aspx

因此可能无法判断输入是否来自真实"键盘.

So there is probably no way to tell whether the input is coming from a "real" keyboard or not.
