I am developing an e-commerce web site using asp.net MVC4, it need to fill the product form(eg. product name, price, etc) and save to database, and i know we can use a barcode scanner to do such stuff(scan the barcode, the form will be filled programmatically). What is the key word that i should google? Any example?
Steps could be:
call webcam in web browser
scan and decode barcode
analyze the result. probably you can make a data structure like
{"name":xx, "price":xx, etc}. extract data from result and fill them into product form.

Is it possible to create a QR code that holds URL + data (numbers) that I can decode from my own app?
Also, I need it in such a way that if someone tries to scan it from a regular QR scanner it will only direct to the URL.
I am reading QR cards on my application to read data (there are few cards in different locations so reading the QR will tell me where the person is).
But I also want to do that if someone that does not have my app and randomly sees the QR code and tries to scan it with normal QR scanners it will redirect him to my app's URL..
Is this possible?
I tried something like this:
https://play.google.com/store/apps/<myapp> 123
and I simply seperate the first string from the second string to read the 123
But when I scan it with a QR reader it redirects to a broken link..
You should specify what programming language you are using.
Anyways, a solution would be to use GET parameters to be read by your app and not by the site.
Example:
www.yoursite.com/?location=Boston
If your app can read the variable location than you are good to go.
Of course the site will have to ignore it.

so basically I'm trying to display the latest tweets from 5-10 different sources/twitter accounts in a new application I'm trying to make.
Similarly the way tweetro/metrotwit retrieve and display tweets in the application. But on a much smaller scale.
Any ideas on how this could be done?
Would be much appreciated.

Simply use the Twitter API to send a Web Service Request accessing those specific tweets in a data friendly format like XML or text. Then simply bind that data to a ListView or whatever pleases you.
Hi am creating a barcode reader application , am able to get barcode number but need advice on where to lookup for product details like price , product name etc ...
Google's Shopping Search API (see https://developers.google.com/shopping-search/) is one of many services that has a simple barcode-to-product-metadata interface and will give you back product data in XML/JSON or other. It's pretty straightforward to use, but if you're unsure of how to make it work, I believe you can look at how the barcode scanning app Zxing uses it (the code for which is available).
