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 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

I have completed a project which is completed on iOS and Android with all native code like in-app purchases and leaderboard completed. I want to convert that project into HTML 5 but without changing my C++ code to javascript and using the same resources. Is there any method/way to convert my code?
I was a native obj-c programmer who joined cocos2d-x porting from cocos2d-iphone. I have little/no knowledge of html or javascript.
If you want the resulting app to run within the browser, then no. There's no cocos2d variant that makes this possible. You would have to port the app to a completely different (but still C++) framework. See: How to build native C++ apps with HTML/CSS UI?
You can of course build a c++ app with cocos2d-x that presents a html5 view, but it won't run within the browser.
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 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/
I have run into a few dead ends trying to get an animated gif onto the clipboard in iOS using Titanium, so that I can then have the user paste it into an MMS.
I am considering trying my hand at creating a simple Titanium Module to get the image onto the clipboard with Objective C. This link has the code to do it.
My question is, can the Titanium Module access the file I have in my Titanium app's Resources folder? If so, I can just pass a path into the module.
If not, then I may need to pass the binary image data into the module (which probably won't work, since using a blob to put the image on the clipboard does not work)
Another approach might be to put all the images inside the module itself.
