I am using a web application which supports VLC plugin to run the video streaming.
For this i have done some approach as follows :
1. Open Chrome and Open url : chrome://flags/#enable-npapi
2. Enable NPAPI
3. Restart the browser.
When i applied above 3 steps then it works fine but from some days chrome doesn't supports these
npapi plugins.
So, What is the solution for it so that i can run
vlc plugin
in chrome as my asp.net application is based on it.
Sorry for my bad English!
From Chrome 45 and foward NPAPI is no longer supported it has been announced for a while now that they would do that by version 45, if VLC plugin relies on it then you might need to wait for an update on the plugin itself or move to other technologies.
The NPAPI page on Chromium.org lists some alternatives:
HTML5 Media Elements
WebRTC
In my opinion, the best thing to do would be to move to one of the newer technologies as Chromium team will probably not revert the depreciation of NPAPI. You could also warn your users to not update Chrome, but that would leave them open to vulnerabilities(Also, most users probably have auto-update enable so...).
Also, this question might be useful
As NPAPI is no longer supported in Chrome, you need to use different web plugin for video streaming, that's all. Browse yourself, there are several good stable ones, I use VXG plugin.

I'm developing a WPF application using Cefsharp. This web browser inside the app should show some flash contents. I found some forum where the users suggest to use papi flash or pepper flash for Cefsharp.
I have no idea how to implement those plugin in my project.
I'm using the last version of Cefsharp.
Someone can explain how to enable Flash contents in my webview?
Thanks
You need to download the PPAPI version of Flash. Every computer running your app must do the same. Visit http://get.adobe.com/flashplayer/otherversions/ and select FP [xx] for Chromium and Opera where [xx] is the current version number, which is 26 at the time of this answer.
I am writing a browser application using C# Language and GeckoFX Browser library.
Now, I want to add the Mozilla Firefox Add-on to my application.
To be precise, I want my application to block undesirable advertisement using AdBlock Plus add-on for Mozilla.
Is it possible to use a Firefox add-on in my GeckoFX control?
Sadly because Firefox extensions are largely based around the interface and working of Firefox's UI, not just the Gecko interface, I don't think it would be possible at all currently to install extensions or .XPI files.
So in order to do this without using an extension, you may have to code an adblocker yourself which I've been trying to do here.
Otherwise, good luck! I've been having similar issues and am looking towards writing my own solution.
I'm developing an MVC app.
If I (on my Surface Pro) goes to http://www.whatbrowser.org/ it correctly says IE 10.
But if I go to my MVC app and print out the Request.Browser.Version, it returns 7.
Any idea why? Is Request.Browser.Version broken?
Thanks
Some of this is touched on in Detect Internet explorer browser version problems.
Last I knew Request.Browser uses the *.browser files that come with the installs of ASP.NET, and easily get out of date. Microsoft releases updates to them every so often, but not often enough. Currently there are some issues with webform pages breaking on IE10 without updated browser files.
Like the comments have said, browser detection is very broken. If you need to detect the browser, at the very least shy away from using the user agent string, and seriously consider why you need to know exactly what browser is used.
Request.Browser.Version doesn't always return the 'correct' browser version for IE because of many factors including compatibility view, meta tags etc.
You would be better off detecting browser capabilities instead. Further reading here: http://msdn.microsoft.com/library/3yekbd5b
As a personal preference, it would be best to detect the OS instead of the browser. Most of the common HTML5/CSS3 features are supported in IE9 and above and IE9 requires Windows Vista and up. The best way to do this using the User Agent is by checking the Trident. If there is compatibility view enabled via the browser or by using meta tags by the app itself, the wrong 'version' is returned but the Trident remains correct.
PS. This isn't fool proof but this would work most of the time.

I was looking for a way to embed a page that hosts WebRTC video such as the demo from http://www.webrtc.org/demo into a WinForms app so the user doesn't need to install nor launch any external browsers that may contain toolbars, etc, I looked into a few components such as GeckoFX and WebKit.Net but they fail to load the webcam video.
Do you know of any hack or other project that may support WebRTC inside .Net?
Thanks a lot
Chromium Embedded Framework claims to support WebRTC (I haven't confirmed it myself).
https://code.google.com/p/chromiumembedded/
http://en.wikipedia.org/wiki/Chromium_Embedded_Framework
WebRTC is supported by Mozilla Firefox:
http://www.webrtc.org/
If you want to embed Firefox in you project you can easily embed GeckoFX web browser control in your Windows Forms application.
The GeckoFX engine (Mozilla Firefox) says it can use WebRTC. This seem to be right (as far as I have seen yet) but there seem to be a problem with some parts of it. I'm using it actual for WebRTC and have a problem with the video part - see here: Embedded GeckoFx in C#.NET - WebRTC Video not working
Can WPF be hosted in a web browser? If so how? (I think it can as I have seen some examples of it.)
While hosted in the web browser what printing support does it have?
What are the drawbacks to using WPF in a browser?
My company is looking for a rich web app platform. They will not choose Silverlight because it ignores any printing needs (at least as far as I understand). Right now a solution from Adobe is in the lead because it supports printing.
Most (if not all) of the apps written for browsers will be used internally by my company (ie we control the computers and browsers). (We want to use browsers for easy of deployment.)
Have you checked out XBAP (Xaml Browser APplications)?
The major drawbacks I am aware of concern security. When some coworkers of mine were developing an XBAP product, they often ran into problems with security, as the XBAP model is pretty strict.
I can't answer about printing, but I'd tend to think that might be a problem with the security considerations.
Hope I was able to help.
If the apps are solely internal and you control the target platform; and the reason for choosing to host your apps in the browser is 'ease of deployment', I would seriously consider writing Full Trust applications in WPF, and deploying them with ClickOnce... Your users would simply have a shortcut on their desktops that would check a server to see if their version of the app is current, and download the newest version if not.
You get all the benefits of the full WPF platform (greater feature-set than Silverlight), and do not need to conform to the Partial-Trust restrictions of XBAP (although you will need to configure the ClickOnce server to allow for Trusted Application Deployment)
No. That's what Silverlight is for right now and yes there are printing limitations. However, printing anything using a web app is not straight forward.
I would suggest Silverlight/Flex solution for web based app and for printing need the best way to do is use iTextSharp library and generate PDF for your reports or printing need, which can be fetched from a URL. PDF is a very standard and adobe reader will always print it right, printing will not be a problem, we went through lot of options and it requires reinventing wheel where else generating PDF through iTextSharp is very easy as creating normal html in javascript way.
