Ajendra: Bar code readers usually plug into the keyboard port (in which case
you read their data as you would any keyboard input) or a serial port (in
which case you read their data as you would any serial input, such as that
of a modem). I'd suggest that you go to http://www.devx.com and do a search
on "barcode" in the Visual Basic library to see if this question has been
answered here before.

Hi,

This depends on how the reader is connected to the PC. If the reader uses a
keyboard wedge (a device that inserts inline with the keyboard connector),
then data are inserted into any windows that has focus, such as a TextBox.
You would then take the data from the textbox and copy it to the database
using standard methods.

If the reader uses a serial port, then you do not need a TextBox or other
window to accept data. Instead, you would have a small amount of code that
takes the serial data (perhaps using MSComm) and transfers receive data to
the database. I have an example of this option in my book. See below for
information. I prefer this technique because it reduces the likelihood that
the user can do anything to mess it up.
