I need to program a QR code reader in my Windows RT app, so I can get the ID of the specific item I am scanning.
I have found the source to a free QR code generator, but I cannot find the code to read the ID from the QR Code, so can anybody in here tell me, where I can find the source to a QR Reader or any other ways to read the QR Code e.g. Install a third-party program, which only reads the QR Code and sends the result back to my program
I would recommend taking a look at ZXing.NET. It's an Open Source barcode scanner library, which includes support for QR codes. There is a WinRT port available on CodePlex. You will simply need to pass an image into the library to read the contents.
I faced the same problem, I had to manually write camera capture capability and then pass it on to ZXing. Check it out here - http://quirkd.wordpress.com/2015/02/18/reading-qr-codes-in-winrt-tricky/

Thanks to the help of Ohgodwhy, I realized that it is possible to use QR code for a advertising, too.(question) Just scanning code shows the banner with options of Open Browser and Install App, it's really amazing.
I really want to realize this. I want to do it in my vue project. The problem is that I am not sure about the preview content of the link of the QR code. I am just embedding the link. The scanned result might show the link and hopefully the preview of the link.
But I am not sure how it would look like. Preview of the link are different on different platforms. Can you help me how to guess the content that will be shown by the mobile device as the banner when it successfully scanned the QR code?
I have to implement a barcode scanner in both android and ios where I need to scan the barcode and retrieve data and bind it in the text field.
There is one official barcode module you can look into that is fully open source. This means you can use it directly in your app on both platforms, AND you can check the source code to see how it is build, and if needed hook into that logic, expand it with your own functionality or add support for barcode types etc.
It is called ti.barcode and can be found on GitHub. It uses zxing under the hood as well.
You can use below hyperloop project as well which uses zxing lib directly

The only information I've been able to find in QR Code scanning for the new AVFoundation-supported scanning is for iOS, and specifically using the camera.
I need to be able to scan for a QR Code in pre-recorded video Quicktime files.
I'm not even quite sure where to begin looking for this.
Basically, I need to open a video file, scan the video file for QR Codes embedded in the frames of the pre-recorded video, and then produce the results.
EDIT:
I attempted a bit more on this. I tried running some code for compiling on MacOS instead of iOS and I get the usual errors, telling me most of it is only supported by iOS. I can't seem to feed the QRCode framework anything in MacOS. There must be a way to do... Anyone out there come across this?
I am develping an app in iphone which reads barcode using ZBar framework. Is there any framework or sample code to re - generate the bar code or QR code?
Sure, ZXing has QR code generating code. It's in Java though, but you could port it -- actually I forget whether it's already been ported within the project.
But, even easier, just call to the Google Chart Server. It has the same encoder inside it. No coding needed to get an image for given contents.
I'm trying to find a free online service that will generate a barcode image for me, when I enter the number (UPC, etc). So far I have only found this site:
http://www.barcoding.com/upc/
and they don't really have an api. They do have a form on that page, and I was wondering if there was a way my windows phone app could programmatically enter information into the form, and then show the resulting image on the phone screen. The page does list the the barcode generator as "a free service", and I would not be averse to giving them props in my app.
On further inspection, it looks like a javascript function is calling an asp file, like so:
var cp = new cpaint();
...
cp.call('buildbarcode.asp', 'BuildBarcode', BuildBarcodeCallback, barcode, symbology, fileFormat);
Would it be fair (or even possible) to call buildbarcode.asp directly from my app? Is there an equivalent of cpaint for c#?
I think it would be easier to generate the barcodes in your application. There are a number of open source barcode tools at codeplex. There's even one there for reading barcodes with the Wp7 camera.
I dont know if there's something to fill in the fields and take a screenshot, but you might be able to use something like this library for generating barcodes:
