How do I capture the Keyboard Emulation?

103 100+

I am creating an application in c# that will take the response sent from a swipe card reader and place it in a variable. If I open notepad and swipe the card, the data is sent to note pad. I would like help in with capturing that data into a variable. Someone had recommended using Window Hooks, but that is beyond my skill level (unless you can explain how to). The card reader is USB powered. Please help. I have been reading and searching for two weeks and all the things I have found are not very helpful to a newbie to component reading. Thanks in advance!

Honestly, Window Hooks would have been my suggestion too. I know you can launch a Notepad instance using the Process class and interact with it at a higher level, but you can't access anything specific.

For using the hooks, have a look here:

This article provides a library that you can use and explains how to use it.
