I need support in SignalR for Android client. I am using following client SignalR/Java-Client but unable to know where to start :) We are completed .net self host & working fine. But only problem with Android & iPhone. Can any one please guide me how to start the next steps for Android & iPhone.
You don't give a lot of details, so it's hard to give a concrete answer, especially since your question is very broad to begin with. Nonetheless, you should have a look at the official samples for the Java client, to get you started. If you have implemented the server side yourselves, and know your Java, it should be pretty easy to figure out from the code provided in these samples. The Java client is, in my experience, very easy to use.
As for an iOS client, a Google search came up with this library. I have never used it, and it looks like it's not getting a whole lot of support, but you could always give it a shot.

Chrome is on the verge of definitly break compatability with NPAPI, and IE breaking with ActiveX the future of Java Applets is dark. Currenty we actively use a secure applet for out client organizations that enables their users to upload a bunch of files from their file system to our servers with the click of a button. The applet has full access to any configured drive, including network drives.
With the imminent death of the applet this functionality is going to be lost if we don't find an alternative. I have already tried to explore different solutions, including the chrome FileSystem API but that is currently only available for Chrome (http://caniuse.com/#feat=filesystem) and has limited access.
Does anybody know about an alternative to keep supporting the much appreciated functionality? Unfortunately we are obligated to support all browser down to IE8.
I've written a post about this here.
Once Google Chrome was the first to announce that they won’t be supporting NPAPI anymore, they were also the first to provide a new architecture in order to rewrite your code to work on their browser. You can take a look on Native Messaging, which “can exchange messages with native applications using an API that is similar to the other message passing APIs”. The problem is that this approach only works on Chrome, is not something that you can adapt to other browsers.
A more useful approach is FireBreath, a browser plugin in a post NPAPI world. Check the words below from one buddy of the project:
“FireBreath 2 will allow you to write a plugin that works in NPAPI, ActiveX, or through Native Messaging; it’s getting close to ready to go into beta. It doesn’t have any kind of real drawing support, but would work for what you describe. The install process is a bit of a pain, but it works. The FireWyrm protocol that the native messaging component uses could be used with any connection that allows passing text data; it should be possible to make it work with js-ctypes on firefox or plausibly WEB-RTC or even CORS AJAX in some way. For now the only thing we needed to solve was Chrome, but we did it in a way that should be pretty portable to other technologies.”
In light of the answer provided by Uly Marins I have researched the options suggested. Unfortunately these options weren't viable for our application, because the mayority of our users do not have sufficient rights to install third party plugins. Additionally the API is still in Beta which won't do any good in a stable production environment.
The main problem we wanted to solve was the abbility to delete files from the accessed folders. It seemed like one of the mayor goals of the removal of the NPAPI support was exactly to prevent this kind of possibility. Therefore we needed to reduce our goals to a simple solution that was still acceptable for our users, with the additional training on how to clear the selected folder manually (because most of our users are almost computer illiterate and needed to access network folders).
Long answer short. The requested solution is just not possible anymore and had to be replaced by a simpler solution and additional training.
I'm writing an iphone application that sends email, sms and make phone calls.
since I can't test from the simulator that any of the code I wrote actually work, I'd like to deploy the application on my iphone without a developer license.
After searching the web and similar questions here I'm still looking for dummies tutorial (step 1...step 2...), can anyone refer me to one
thanks
TestFlight provides an easy ad-hoc distribution system for testing apps. It's easy to add devices and their documentation is very helpful. Their website is https://testflightapp.com/dashboard/. And here is a great step-by-step tutorial http://mobile.tutsplus.com/tutorials/iphone/testing-with-testflight/.
I've just discovered TideSDK and it seems to be a really great tool, but I have one requirement : I need to use some native code (for managing USB devices for example) and so I need communication between this native code and the web app, is such a thing possible with TideSDK?
Yes, working with native code in TideSDK is possible. Our SDK is modular and we have been reorganizing the code structurally to make it easier to do the sort of thing you want. At a modular level, you will be contending with support for multiple platforms typically.
A module should extend to all platforms that you are supporting. We expect to have documentation to help developers (familiar with native code) to better understand the SDK. This should include some module boilerplate to help you get started. At this point, we have yet to prepare this more detailed documentation. We have much to do and sometimes progress seems slow despite all the great efforts going into TideSDK.
TideSDK is a large and complex SDK but don't let this frighten you off. It is extensible and we will be shining light on this soon with module development guides. It would be cool to talk more on IRC about this with you so feel free to drop by at any time. Perhaps the functionality you are speaking of is of general use ie. to extend the APIs for everyone.
There are possibilities to work together with the core developers of TideSDK on modules and to contribute to this great open source project. Other possibilities also include sponsoring module development if this something that you need more immediately for a project. Hope this helps.
Does anyone know of a commercial or free .NET CF library/component/api that I can use within my Windows Mobile 6 and .NET CF 3.5 application?
I need to: enumerate the list of available WiFi networks in range, connect and disconnect specific SSIDs/networks in the list, and manage switching between SSIDs programatically (e.g. I'm currently connected to "public1" and want to switch to "public2" to do some stuff, and then switch back to "public1").
I have tried the OpenNETCF library for this and it somewhat works, but it's crashing quite often with Native Exceptions, which I can't handle with a catch() in my C# code so they bubble up to the end user and they get a nasty windows crash screen with the "send" and "don't send" buttons.
OpenNETCF forums seem to be dead, with lots of posts but no replies to most of them, and the last release from those guys was way back in March 2009.
Last I remember the OpenNETCF code was decent and worked without any issues on a number of devices I tried it on. I certainly don't remember getting native exceptions from it.
Is it possible that you're working on a customised platform? It is possible that the real issue might be due to modifications made to your particular device / operating system.
IIRC we eventually switched to Summit cards for hardware or cost reasons which uses a different API but obviously an API that would only work with Summit cards.
I'm afraid I don't know of any other alternatives atm. Sorry. :(
I'm using Chrome 5.0.375.86. Can anyone point me to a working example of an HTML page communicating (or at least establishing a handshake) in Chrome with a C# (faux) web server?
The current version of WebSockets in hixons-76 (or whatever) and not -75. What does production Chrome currently support? I think it's -75. Do I need the nightly build for -76?
This is also a nice example (The author says it should work with -76)

Heres a Related Question on SO, Should help you to get started
Maybe you will find useful my demo http://programistka.com/en/websockets-c/ which uses two open source libraries - one for server and one for client. In my opinion it is really worth to check them.
