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.

See this[^] example.

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());

I suspect your iOS code is buggy.

but I tried it with more than one iphone..

Are you saying you ran the same code on more than one iPhone?

|
|
|

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.

so you mean the coded I posted is correct and exported vcf should work on iPhone? do I need to add any special element in the file to make it compatible with iPhone?

That's a researtch project for you. I have no idea and I've got my own research to do on my own problems.

You have already posted this question in the .NET Framework forum[^].
Posting the same question in multiple forums on the same site is only going to annoy the people who would otherwise be trying to help you.

Hi,
I need a code for printing a receipt in a WPF (C#) application using PrintDocument or another one else.
Thanks
|
|
|
|

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.

|
|
|
|
your code is totaly right but still some thig error is held in this code so please check it oncve again please 
|
|

Uhhh...Just who do you think you're replying to?

Another way is:
1. Create RDLC or Report File for as per your print document requirement.
2. Assign DataSet to you report file.
3. Create PDF file in specified location.
4. Using Browser control you can show it in pdf viewer in you apps.
5. And Generate print from pdf viewer.
