Hello Experts,

Happy New year!

I have created a web application where

1) the user enters some regular data(name, the Item he is claiming for return etc.).

2) The submitted form creates a unique string and creates a Barcode image

3) That barcode Image is printed on the PDF form

4) Now if I scan the barcode that is on printed PDF, it should display the place where this claim exists in warehouse.

In the above steps, I have succeeded until Step 3.

I have never worked with any Barcode scanner earlier so I would like get some ideas /suggestion/ tutorials that can help for actual real big step 4.

Please do not tell me to google. I have been there and nothing helps much with .Net. Most of the links are in JAVA which I am not looking for.

I want to know how to start tying the scanner to my web application?
I also want to know how to write a program that actually scans the barcode from printed PDF and display the results from the Database.

Any sort of help is much appreciated!

Thanks

If the "scanner" is on a client machine, VB.NET/C#/ASP.NET code is out of the question. ASP.NET code runs entirely server-side and does not have access to the client machines, let alone the hardware attached to them. Your only solution is a Javascript solution.

I am not afraid to use JavaScript. But "how" is what I need.

I'm reading the comments below and have found that the question you posted above has nothing to do with the actual problem you're getting into.

May be the wordings are put incorrectly. But now the other Expert is trying to help me as he/she is getting into this. I would appreciate if you can throw some light in this grey area
If you're using a barcode scanner with USB connection, it will have keyboard emulation. Meaning it will appear to the PC as a keyboard that's sending keystrokes when you scan a barcode. You just need an input control and make sure it has input focus before scanning. That's it. No special software required at all.

Yeah I am using USB scanner.
But how do I use that scanner to scan the barcode that is generated by my ASP.NEt VB.NEt web application and get the details from Database. I am not quite comfortable with scanner because I haven't worked before. So this is completely New. Please talk in layman terms. To scan a barcode on PDF and get the Rack number that Claim is sitting in is all what I need.

Let's assume for a moment that you don't want to use a barcode scanner but instead enter the codes manually. Would you then know what you need to do?

nope. But what I need here is to scan the barcode image (that is generated by my web application) on the claim (printed PDF)
Sascha Lefèvre 6-Jan-16 13:45pm    
Yeah sure. But then your problem apparently is not related to barcode-scanning. So what's the actual problem?

See, I have created a web application where user enter all the Claim details that is supposed to return/ claim return .
And there is a unique alphanumeric string that is generated by my program and that string is converted to Barcode Image using Keep automation.dll .
Now that image is placed on the top right corner of a paper (printed Claim).
I have people who will work on this project and they will scan the barcode on the printed claim and know where the related products are placed in Rack/Bin in huge warehouse.

I am stuck with last step. I want to know how they can scan and relate that to my Program and get the details on the scanner.
