Hi Bernhard,

thanks - Adding the jsessionid to the uri already helped solving my first issue - then changing uenbld to uenbId did the final trick.

Thanks for the quick and helpful response, highly appreciated.

Question answered!

All a bar code contains is an Article Number (AN) - which is a unique identifier for a product type. So a 100g chocolate bar will have one AN, and a 100g chocolate bar from a different manufacturer will have a different one. a 200g bar from the same manufacturer will also have a different AN.

What that means is that you can scan teh product barcode, and get a number which lets you go to your database, look up the AN and get told "this is a Cadburys Dairy Milk 100g and we are selling it at £1.50, we have 72 in stock and we reorder if the stick level drops to 71". Without the user or operator having to enter any information (with the good probability that he will make a mistake).

It's not security, it's just a number (which contains a simple checksum code) which identifies something. Everything else is a database / application function.

(There are barcode types which contain more information than this - a lot more in some cases - but that's the general idea)

Hi,

Is it possible to generate vcf contact file using C# and .NET 4.0? or need to use thirdparty only?

Thanks,
Jassim

Yes, it's possible. Assuming you are a reasonably competent C# programmer, and know how to use Google to find the documents that define the vCard format.

I managed to generate the vcf file using the below code from your reply and I am able to open it on my PC and m Samsung Galaxy S5 but not the iPhone. Why is that?

var contact = new GoogleContacts()
{title = "Mr.", first_name = "Kookoo", last_name = "NooNoo", work_phone = "17171717", mobile_phone = "39393939", email = "jassim@myemail.com", im = "jasmanskype" };

var vcf = new StringBuilder();
vcf.Append("BEGIN:VCARD" + System.Environment.NewLine);
vcf.Append("VERSION:3.0" + System.Environment.NewLine);
vcf.Append("TEL;type=HOME;type=VOICE;type=pref:" + contact.mobile_phone + System.Environment.NewLine);
vcf.Append("FN:" + contact.first_name + " " + contact.last_name + System.Environment.NewLine);
vcf.Append("END:VCARD" + System.Environment.NewLine);

var filename = @"C:\temp\mycontact.vcf";
            
System.IO.File.WriteAllText(filename, vcf.ToString());

Uhhh, if your code is buggy, how is changing out the phone going to fix that??

You might want to try and find out if the iPhone can successfully read and process a vCard file and/or what it's looking for in the vCard.

OK. The only code you're going to get is the code that YOU write yourself.

Nobody here is going to do it for you and just Googling around for "print a receipt from a WPF app" is going to get you some vague code samples that you're going to have to adapt anyway.
