Keyboard based barcode scanners.

[Frank Rizzo]

I have a barcode scanner that hooks up to a keyboard port. I've figured
out how to setup a system-wide keyboard hook. However, how do I
distinguish regular keyboard input from the barcode scanner input. Does
anyone have any ideas?

Thanks.

I cannot imagine that it is possible.

That is like trying to detect a hardware keylogger. Not gonna happen.

You cannot! The only way to detect is to calculate the speed of completion
(even this won't be sure because it could be a Paste operation).
