I want to access OMR Scanner through web application. I have search for it in google and found ScanTool SDK, but I am looking for similar functionality but open source. My basic requirement is below:
There will a web interface for the user.
User can select OMR scanner from the web page drop-down.
User can do the scanning of the document
NOTE: I have seen similar functionality for TWAIN scanner. But I want it for OMR scanner. As TWAIN scanner generate image data but OMR scanner generate image as well as raw data of response present in OMR sheet.
Please see my answer her regarding scanning via the web:
How can I scan a document using ASP.net MVC 5 with the help of Twain
Basically you will need to install some sort of client side service that will interface with your scanner's driver in order to scan via the web as there is built in security functionality that prevents the browser from interfacing directly with the client's scanner.

I'm Creating a Python Web crawler, with the ability to browse web history & parse through the information and store important information within a Database for Forensics/Academic Purposes. I understand the functionality to browse web sites but the part I'm struggling with is to be able too crawl through web history I will give a scenario:
During Forensic Investigation.
You have been given a full Forensic Image of Suspects Computer, you then locate the AppData folder for Google Chrome which stores all information about suspect including form information, credentials & web history.
How would I set up the web crawler to only search through data in the suspects web history.
I am also having issues accessing the information stored within Google Chrome User Data to try view my personal information which is stored here as a start, I am currently attempting to use DB Browser to view the files to try see my own web history however I'm not having much luck with this. Any Suggestions
For those interested in this project of mine I can update this thread as I go so you can see the progress of my web-crawler the end result will have the ability to take web-history and data from public & private websites sort important information i.e. name, address, D.O.B into a database for to be used later as a biographic dictionary.
I WILL STRESS THIS AGAIN AS THIS IS ALL FOR ACADEMIC PURPOSES IN CONTROLLED ENVIROMENT AND USED ON A TEST/FAKE ACCOUNT
Hindsight (https://github.com/obsidianforensics/hindsight) is an open source tool written in Python that can parse a ton of information from the files in /Google/Chrome/User Data/ directory.
You could look at it's source for inspiration, or just run the tool and parse its output (it can produce XLSX, JSON, or SQLite) in your crawler.
Is there any way to launch another App from one APP
So, I need to scan a QR code, and do something with the code.
There are 2 type of solution,
Launch an QR code reader app from current app, scan, and return.
But I don't know it's possible or not.
Porting Zxing
Then hook up Zxing with the camera in WP
So I want to know is solution 1 possible?
Where I can find a sample about launch an app from an app
You can run your application from another application.
For example
Windows.System.Launcher.LaunchUriAsync(new Uri("viber:"));
But it's impossible to pick just so the results from another application.
Better for you to embed the code in your application to read.
There are libraries. For example, ZXing.Net 0.14.0.1
Yes there are many libraries out there in order to use the QR Scanning, where this sample from Wilcox could be helpful. Another option you could go with is to use the ZXing.Net.Mobile client for QR scanning.
Sample
Why don't you try launching the Bing Vision from your app in order to do the scanning?
Is it possible to access bing vision programmatically
Short version: I have a WebBrowser control hosted in a Windows Phone 8 app. How can I store values from javascript so that they persist across the user closing and reopening my app?
Long version:
I'm developing a Windows Phone 8 application that has a single WebBrowser control hosted in a single MainPage.xaml page that lives for the entire life of my app. I created the app with the "Windows Phone HTML5 App" project type when creating the project in Visual Studio 2012. 99% of my application is hosted in web pages (on the internet, not stored on the phone) that I direct the WebBrowser to go to when the app starts up. In my application's web pages I'm trying to persist data across pages and across sessions. For example, once the user logs in once then I want to store that on the phone so the next time they start the app they don't have to log in again.
Cookies and HTML5 Local Storage (via window.localStorage.setItem and getItem) both work fine for sharing data across pages in the app while the app is running and even if you switch out of the app (via the Windows phone "hard button") and go back in. But if the user exits the app by pressing the hard "back" button then the next time the app is started all localStorage and cookies seem to be gone.
Is this the expected behavior? I guess I'm not sure where WebBrowser would store the data (Isolated Storage? Or maybe in the same place it's stored if going to the web site with Internet Explorer?). In any case, if there's no "fix" for this, can anyone the best way for me to provide my own storage mechanism so that I can let my javascript code persist values across instances of my app running? I'm happy to use the app's Isolated Storage if only I knew of a way to get and retrieve values from it using javascript. Thank you.
I'm not sure if this is expected behaviour or not.
To get at the Isolated Storage you will need to use JS/.NET interop.
if you want to trigger the persistent storage from JS:
Use window.external.notify in JS, generating a JSON string (for instance) to pass along to the .NET side. That could be written to IsolatedStorage without the .NET having to parse the data. You could use IsolatedStorage.AppSettings or a full file depending on the size of the data.
Alternately you could trigger the process from .NET:
Call WebBrowser.InvokeScript to call a JS function which returns the same JSON string representing your data.
The .NET side could detect and restore this data on startup and use WebBrowser.InvokeScript to pass the JSON string back into the WebBrowser via a JS function.
You'd of course have to deal with error cases (attempting to restore bad/corrupt JSON).
Also, if you trigger this from .NET in response to the App.Closing event you need to watch out that you don't take too long writing data.
The faster you run the better, but this definitely needs to be done within 10 seconds or the OS will kill your app.
See MSDN docs for WebBrowser.InvokeScript() and ScriptNotify registration to window.external.notify.
i know that the index.html page (the PhoneGap startup page) needs to reside on the device. but if we want to create an app who uses third party user authentication before proceeding to core application, so then what we have to do?
Thanks in advance
On android you can change the starting page in the main activity or you can make a redirect in index.html
Well, you don't say if you are platform specific..
And there are lots of third party auth options..
But I can offer two solutions (admittedly my own code etc),
both of them use PhoneGap for Android and PhoneGap Plugins. The key piece of code for me has been the onLocationChange callback feature of the ChildBrowser plugin. Your app can take the user to other sites for auth or whatever, but still get control back.
Tutorial on Using Twitter REST API (OAuth 1, ChildBrowser, jsOAuth plugin)
Free Android App + Source on github : AppLaud App (OpenID, ChildBrowser, custom server)
For authentication, you can have a form in your index.html (maybe under login div) to do a post to an actual webserver.
Then, fetch the data returned from the webserver to let your user access the functionality of your native phonegap application.
You can have the functionality disabled until you receive the successful login from the webserver. If you post via ajax, the webview won't even blink, but you will still get the successful login response from webserver and simply enable functionality on your app after this.
Let me know if this is confusing and I'll try to explain more clearly and
I hope this helps.
I am using a Java based Portal Platform. I need to show within my portal information stored in Lotus Notes. Considering security issues, what are the recommended ways to do this?
Are there any open source JSR 168 portlets out there that integrate with Lotus Notes?
From my portal platform, I can call web services to get this information. Is this recommended? If so where can I find information about web service API´s available for Lotus Notes?
Are there any java components that I can install on my portal platform that will make available a java API to access Lotus Notes information?
You have two main options.
First you can talk to Domino (Notes is the client, Domino is the server) directly using the CORBA java interface over IIOP. This will give you full access to the Domino object model and allow you to write the code to do whatever it is you need to do in your java platform.
Secondly you could go over web services. This will be much easier to set up, but you will have to deploy code for what ever it is you want to do on the Domino server. In ND7 and up Domino will build all the web service elements for you from a WSDL or method stub.
From a security point of view, the user connecting to the service will need to be authenticated with Domino. This could be a system account or the actual user if you can proxy the login through.
Another angle I've seen is to just proxy HTTP calls through the portlet to Domino.
Assuming you have SSO setup between portal and domino the simplest solution is to use the Notes View Portlet included with portal. If you need to show the data in a more customized format then I would suggest to use portlet factory. If neither of the previous work for you then you should be able to develop a custom portet using RAD and the notes java api.
