Low-level Windows API hooks from C# to stop unwanted keystrokes

Introduction

Cats and babies have a lot in common. They both like eating the house plants, and share the same hatred of closed doors. They also love using keyboards, with the result that the important email you were sending to your boss is dispatched in mid-sentence, your accounts in Excel are embellished with four rows of gobbledygook, and your failure to notice that Windows Explorer was open results in several files moving to the Recycle Bin.

The solution is an application which you can switch to as soon as the keyboard is under threat, and which will ensure that any keyboard activity is harmless. This article illustrates how the keyboard can be neutralized in a C# application using a low-level Windows API hook.
