Hello
I have a table of players, each player in the team should have unique barcode: 
The barcode scanner returns an array of chars.
The next player_id = char++, example: aaa
aab
aac
...
aba
aca
..
baa
Or muybe another solution?

Both UPC and EAN barcodes encode just sequences of digits; which encoding do you have in mind?
kind regards,
Jos
Thanks but i am sorry to say I don't understand your response.
I asked what should I do to generate a barcode on basis of an array of chars?
All I know is when I take the barcode reader and scan a barcode, the output is like this in (player_id)

I don't think that barcode reader gives your (16 bit or utf-8) chars; it just gives you bytes. Read those bytes and use them as a unique id.
kind regards,
Jos
@JosAH
Thank you, that is what I also do, the string or bytes I get as return value when I read a barcode with barcode reader, I use it as unique id.
I am now looking for a good working solution on how to generate a barcode which gives you the code (bytes for example) you have in the table as unique id.

I don't understand what you want then; you have a unique key (a byte[] array) produced by your barcode reader; you have your data that belongs to that key so what other key do you want?
kind regards,

That's easy; there are numerous packages available that can print barcodes for you; google for "print barcode Java" and see for yourself.
kind regards,

Hey all,
I've written a VB.Net app that creates picture badges complete with
barcodes. The problem is that the barcode quality is not good enough
to be read by scanners. I'm using the DRAWSTRING function to place
the barcode on the image, but no matter what graphics settings
(.InterpolationMode/.CompositingQuality etc.) I manipulate, the barcode
image remains poor quality. For exaple I'm using a solidbrush that
is black, but some of...

Hi,
I am in the design phase of building a database that will track the

scanner to assist me with this. Employees will hopefully be scanning
a barcode which will communicate to the computer that the employee did

will contain string data to identify them and hopefully log them in.
Is this a good way to keep...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
