I am trying to make a barcode application.
I have my own finished program but customer wanted me to make it work
with card system, So i need barcode programming.
I know it is working like, it sends some numbers or keys to a field.
But how can it know which field or which textbox to fill in?
Should i write some codes where to send?
Or how it works..
Thank you..


When I was doing this (back in the day) we had a couple of keystrokes
just ahead of the data so that we knew where it was supposed to go.
IE: "PTxxxxxxx" and we would capture the "PT" so that we knew it was
a part number instead of an employee ID.

Out of curiosity, with OOP, can you capture the keys, with a keydown
event like that without having to capture every single keystroke?
