For barcode scanning there are modules available like Redlaser,Scandit..etc.
Is there any module to generate barcode from number(reverse procedure)?
Thanks.
A nice trick to avoid the main of modules, you can simply download a Barcode font, embed it in your app, and simply show a label with the text and the barcode font.
Be sure to check if the font is real, some are just artists conceptions and do not generate actual barcodes. Just make a few tests with a scanner app before you launch!

There is Scandit api's available for this implementation Here is the working example link,
Here is instructions how to use it.
Hope this may help some one else also.
Thanks.

Can Any body suggest how to implement.
Try using React-native-svg-charts

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'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:

I am working on the PDF App for iPad and facing an issue: how to search a text in PDF and also how to highlight that text?
Yours is the same big problem I'm having. My understanding is that, currently on iOS 4.0, the main public API is CGPDF . It allows us to parse PDF, and with it we can search strings in it. See also this Quartz 2D document. It also allows us to render it on the screen using CGContextDrawPage. However, it's not yet possible to get the position of a text in the rendered image. (On OS X it's possible using PDFKit.)
So, I'm afraid that you need to implement the PDF spec yourself to get that info. I think GoodReader etc. is working very very hard to implement these.
I had the same trouble recently and then I found FastPDFKit. Have tested the package and it's working great.
