Overview

Hooking into the Windows API is complicated process and there are several techniques to achieve this.
Microsoft recommends that the callback procedure for most hooks should reside within a DLL, this is the
method used in the TCPKeyHook Component. The Component encapsulates the procedures and functions
within the separate DLL and uses custom messages to send the key information to/from the application.
The result is system wide access to the keyboard generated data before being passed back to Windows
for further processing.

Always place the KeyHook.DLL into the same location as your project or anywhere the path can find it.

Quick Start Steps:

• Place the component into your current project.
• Setup the OnKeyPressed Event.
