Manage Your User's Keyboard with the Windows API

摘要

In last month's article, you learned how to use a Keyboard class I had written to access functionality surrounding the Windows keyboard. In this article, you'll investigate the code inside the Keyboard class, to see how it works. In order to do its work, the Keyboard class calls a set of Windows API functions which you can call yourself if you don't want to use the class module or just want to know how the class works. To make it possible to call all the API functions the Keyboard class requires, the class starts with a large set of API declarations including, for instance, a constant that represents the ScrollLock key.
