I'm creating a Silverlight application which can push notification to other users and I want to display the message to the Browser (my users use IE and Firefox to access my website). I noted that some web browsers such as Chrome, Firefox, IE support display Notification when we access to websites which has notification feature. So how can I do this for both Firefox and IE like this? I'm trying to find the solution but due to my quite bad English I still couldn't. Thanks alot.

I'm developing a software on C# which has to get info from a website which the user opens in chrome, the user has to input some data and then the website returns a list of different items.
What I want is a way to be able to access to the source code of the page in order to get the info, I cant open the web myself as it doesnt show anything because I didnt input any data, so I need to get it directly from chrome.
How can I achieve this ? A chrome extension ? Or can I access to chrome directly from my software ?
Off the top of my head, I don't know any application that gets data directly from an open instance of Chrome. You'd have to write your own Chrome extension.
Alternatively, you can open the web browser from your application initially.
You can look into these libraries for doing so:
Watin (My personal favourite)
Selenium
Awesomium (You'd have to roll out your own UI, it's invisible)
Cef
Essential Objects Web Browser
EDIT: I didn't think about using QA tools as the actual browser hook as #TheAnathema mentions. That would probably work for your needs.
You're going to need to create it as Chrome extension if you must be dependent on the user actually going to a specific web site (i.e. not being able to do the requests yourself with either Selenium or standard web requests in Python).
The reason why a Chrome extension would be required is because think of how bad it could be for any software to easily read the pages you browse. Banking, medical, email, etc. could all be accessed anonymously from any process if Google allowed any outside process to tap into the web page.
Even Chrome extensions have to ask for permission to be able to do what they want, but at least it is software the user knowingly installed and agreed to the permissions.
A quick search yielded this example of modifying a page's HTML with a Chrome extension: https://blog.lateral.io/2016/04/create-chrome-extension-modify-websites-html-css/
It sounds like you want to do web scraping. Here's a good tutorial to get you started: HTML Scraping.
And this answer has a good example of how to scrape data from a website where you need to submit a form to get access to the data.
I've just taken a Facebook app live (ie: it's a web app that lives at apps.facebook.com). The app is a simple form that allows you to vote for one of four options. When submitting the form for the vote we also capture the FB ID in order limit the user to 4 votes per day.
When testing this app in sandbox mode as well as live in any browsers, the app functions fine. It even has exception handling in the edge cases where the user is not FB authenticated etc.
The issue we have encountered is that when a user visits the app from within the iOS Facebook app, the link opens within the Facebook in app browser (based on the iOS UIWebView component I believe). When using it from this environment, when the form submits our server is producing a 500 error.
Now I know that the 500 error will be nothing to do with facebook since it is our application code, but my confusion arises from the fact that this only happens from the Facebook in app browser. We are currently going about trying to determine the nature of the 500 error (we do not have access the production environment and custom errors have been switched off).
My question is this: Does the Facebook in app browser behave differently or do things differently than the standard UIWebView or iOS Safari?
I am thinking of differences such as interfering with POST data, clearing FB login credentials etc.
In short yes the Facebook in app browser does behave differently than the standard UIWebView and iOS Safari web browser.
The Safari web browser and the UIWebView do use different user agents.
The Facebook embedded browser doesn't seem to post hidden form values. And I can't seem to find any debugging tools for the embedded browser used in the iOS app.
I might not be 100% true on this one but i think Facebook might still be using this browser for the iOS app. But support for this library has been discontinued and has not been updated in over 2 years.

So in short the answer to your question is Yes, but finding a solution for this issue is another story.

Good Luck!
I have a ASP.Net page for our company and we are running a parallel testing to the new web site. Now, the I attached a clickable image on the old website which redirects to the new web site.
My problem is the old website can be browsed in any web browser while the new web site must only be opened using a specific web browser (due to the developers of the new web site said that it only works properly on google chrome).
All I need is when when they browse the old web site using whatever browser they have, and then click the image, it will open the new website using google chrome.
These web sites are published on the company's windows server, and all clients that connects to it has google chrome installed with them.
If there is something like:
System.Diagnostics.Process.Start("chrome.exe", <url>);
that will be executed on the client side (not on the server side), kindly advise.
This is not possible unless you have some client software that can receive a call from the website to launch Chrome. My answer can be backed by this question about IE redirection to other browser. The accepted answer is absolutely correct.
The security risk would be too great and besides windows doesn't support that kind of linking. You could write a "client" program that runs in the background waiting for a call from your website. Then the client program could launch Chrome.
Hope this helps you!
Is it your problem ? : you want to open your link via Google chrome .
if yes , you cant do it !
because ASP.net , PHP and etc .. a server side language and cant do it ! , its not possible without have any application on clients .
Say I have a mobile optimized website which runs with a lot of javascript on it to create awesome effects, and a user enters the website via a mobile browser which doesn't have javascript activated.
Is it then possible to (through a button click) redirect that user to his/hers browser settings?
You need to have JavaScript activated in order to browse this site properly.

In principle, you can create an intent: URL that references an ACTION_SETTINGS Intent, though I have not tried this. Off the top of my head, the simplest way to construct that URL is to generate a scrap Android project and call:
Log.d("Something", new Intent(android.provider.Settings.ACTION_SETTINGS).toUri(Intent.URI_INTENT_SCHEME));
then check LogCat for the URL that you would put in the Web site. Of course, this URL will only work on Android devices.
I only know Windows Mobile (and there, only up to v6.1), but I would guess your clients would have to have some app of yours prior installed to access features of the device itself.
If websites could access a device's features, it would be viewed as a virus.
I wanted to make an application wherein you specify the name of the websites, your username and password and that application automatically logs in to all your accounts in the specified websites. I have done this using windows form application, using a web browser. But i wanted my application to open all these websites in chrome and log it in there. Plz Help
I'd check out the chrome API failing that
Look into getting a handle to the window through window API calls
But why not just a chrome extension?!? Miles simpler
Have a look at Selenium WebDriver
Doing a quick Google search for "chrome C# api" turned up a number of results I think you may find relevant.
I thought the following were particularly promising, if you're willing to accept a few concessions:
Automating Chrome Browser from C#
ChromeDevTools; a C# Library to interact with Chrome's Developer Tools
Chrome Debugging API
