C# and Bar Codes

[Robert]

Has anyone had experience with using bar codes with C#. I have a client who
wants to read a bar code with a patient's number on it and then look up the
patient in a database. I know they will need a scanner and decoder but what
will I need from a C# programmers perspective to read in the results of the
scan?

Most scanners (Symbol, HHP, etc...) provide an SDK that allows you to
configure and read scan results.

If you use a keyboard wedge type USB scanner, then the data will appear as
if it were typed in via a keyboard.

It really depends on the application. For example, we are using Symbol
Wireless 802.11 scanners (running Windows Pocket PC) because we need the
ability to move freely in the warehouse.

Some clients use a tethered scanner (hooked to a pc) because the are sitting
or standing at a register.

Symbol is a well known brand.

I have used Welch-Allyn scanners before, and can recommend them.

Thanks

Hi,

well the scanner we use is hooked between the PC and the keyboard, this
makes handling easy since the data from the barcode comes with a
keydown-event ;-)

If you need to print the barcode, too, I would provide you a class
collection capable of the following barcodes

128
93
39

I had no time to implement more but they will follow...

Regards,

Martin

not done it in C# but in vbsux we use barcodes. . .

the barcode reader is just another input device like the keyboard.
you press the button on the reader and it sends keys to the app just like
hitting a key on the keyboard. the end of the barcode is a new line.

The barcode is just a font that needs to be installed.
just draw the string that was 'typed' in by the reader in the barcode font
to a canvas.

make sense???
