推荐答案

你会必须安装全局键盘钩子，跟踪活动窗口以了解何时输入到不同的应用程序或输入控件，并在自动完成时模拟击键。



如何通过简单的网络研究找到这个：

SetWindowsHookEx函数（Windows） [ ^ ]

SendInput功能（Windows） [ ^ ]



但你有没有想过可能的副作用？



这是一个安全风险。您的服务还将在内部捕获并存储用户名和密码。因此我不会使用它;特别是当它提供自动学习功能时，不仅可以临时存储输入的字符串。

You would have to install a global keyboard hook, track the active window to know when input goes to a different application or input control, and simulate key strokes upon auto completition.

How to do that can be found out with a simple web research:
SetWindowsHookEx function (Windows)[^]
SendInput function (Windows)[^]

But have you thought about possible side effects?

It is a security risk. Your service would also catch and store user names and passwords internally. For that reason I would not use it; especially when it provides an auto learning feature which stores entered strings not only temporarily.
