in C# or VB.NET yet?
If so which brand did you use, did you run into any specific problems?

Ive done barcode work in VB6, I dont see anything that would change in .NET, all it is is manipulating a string input/output.
I cant tell you what brand they were, sorry.

Im wondering how does the scanner work... was there an API to help you or does it include some kind of a windows driver?
thanks!

The scanner is no more that a keyboard. When you scan a barcode, its just like typing in (let say) 10 keys. The only requirement is a set of fonts you need to install on your system. So to display the scanned item in a textbox, you will set the Font of that textbox to whichever font your scanner uses.
Some fonts: (not free)
Code 39
Code 128
Code 93

they have free barcode font samples - good for testing whether your reader works or not. The thing is they are missing certain numbers - hence the free-ness

I did not know that. That is very cool and sounds easy to use!
One other thing, can you recommend a good scanner? Ive been tasked with deciding which one to use...

Ok were going to use Code 128 fonts with a USB CCD scanner. Reason is that fedex ground uses Code 128 to encode their labels which we need to decode.
Thanks to all who helped!

hey... read above before going to the last post... youll find answers to your questions.
do you have to program the keyboard input ? NO
do you have to program the bar scanner input ? NO
Just like a keyboard. Keep that in mind

Siobi, I understand youre new to this board but please read the thread before reviving a three month old thread, the answer as Ive already stated is in my second post.
Scanners work as keyboards, as simple as that, when you scan a code its input is a string, like the one sent by the keyboard, if the control youre on in that moment is a textbox itll recieve the string, you can catch it and manipulate it, even you can add in the configuration of the scanner if you want at the end of the string a character or something.
We created an application thats used in every store around the country for inventories, and when a product arrives to the store the use the scanner to capture it

I thought bar codes where more secure then that lol

Yes a scanner that relays its info back to a server may be more secure.

Yeah... maybe we shall put a firewall or something like this on the wire between the bar code scanner and the computer. 
What do you think iebidan ? Shall we hire bodyguards too ?
Security shouldnt be thight... do you "protect" your keyboard ?
As I know... standard barcode scanner (those with a wire less than 6 feet long) only return string to a program that is able to receipt them (notepad).
And why should we protect what they scan ? its a code anyway. a code that is link to informations in a DB. The information in the DB arent transfered by the barcode scanner.
yeah.... Ill search a barcode scanner with improved security on ebay.

Why is everyone blowing this out of proportion? It is a valid question to which I addressed in my last post... Because if you do have a connection wireless or not being sent to a common server you do need some security.

Well... I havent seen much of barcode scanner that are wireless...
But...
Why are we still talking in this thread ?
This thread was about implenting a barcode scanner. But around the whole subject I think... at least enough for a beginner to implement that

Well, answering to the main subject of this thread, yes Ive implemented a barcode scanner using C++, what brand???, IBM
now, using a wireless scanner will be useless for a hacker or someone, they will only get the code sent to the computer the scanner is an input ONLY device, if they dont have the database where the information is stored is useless, so no, no secure scanners needed nor encryption, is safe enough
