Creating a Process in the background that will listen to keyboard
提问by Giora Ron Genender
I have a project that runs in the background in a different process, I want it to be able to react to keyboard everywhere, for example I run the project, and afterwards I do other stuff in the computer such as browsing, facebook, watching movies etc.., and every time I press F9 I want my project to show up. Same as how you press a combination of keys to invoke Babylon... I want to implement it in C#, I have no idea how to begin.
我有一个项目在不同的进程中在后台运行，我希望它能够在任何地方对键盘做出反应，例如我运行该项目，然后我在计算机上做其他事情，例如浏览，facebook，看电影等等，每次我按 F9 时，我都希望我的项目出现。和按组合键调用 Babylon 的方式一样...我想用 C# 实现它，我不知道如何开始。

You can register a hotkey with the RegisterHotKeyAPI function. You can see an example of its usage from C# here.
您可以使用RegisterHotKeyAPI 函数注册热键。您可以在此处从 C# 中查看其用法示例。

I think you need to write a system-wide keyboard hook, check here for details:
我认为您需要编写一个系统范围的键盘钩子，请在此处查看详细信息：

How do I grab events for all applications? An example system-wide hook.
