如何捕捉键盘和鼠标事件？ [英] How to catch Keyboard and mouse events?

问题描述

我想创建一个应用程序。当用户按下键盘上的特殊键或/和使用滚轮时，此应用程序必须执行某些操作。此应用程序是一项服务。它没有窗户。我想要抓住任何键盘或鼠标事件，这是用其他应用程序设计的。

I want to create an application. This application has to do something when a user presses special keys on keyboard or/and uses scroll wheel. This application is a service. It has no windows. I want to catch any keyboard or mouse events which were designed with other applications.

例如，您正在通过第三方应用程序观看电视。如果您按 Ctrl + Shift 并使用滚轮，我的应用程序会更改音量。

For example, you are watching TV by 3rd party application. If you press Ctrl + Shift and use scroll wheel my application changes the volume.

我使用Windows 7 x64 Visual Studio 2008。

I use Windows 7 x64 and Visual Studio 2008.
