Does Microsoft Lync 2010 Client support multi-client audio/video conferencing?
If by Multi-Client conferencing, you mean more than 2 parties, then yes, this is supported - but you'll probably get a better answer for this kind of question on serverfault.com

I got a Samsung Smart TV UE40D8000 (Apparently from 2011 series ?) and an iOS device.
I'd like to make them both exchange information (most likely small chunks of text), via a dedicated app on both sides;
Now, it turns out the best way would be to use the Convergence API : I've built a basic TV App that looks an awefull lot like the sample code they give, and an iOS App for UPnP discovery and sending POST requests onto the TV. UPnP discovery works great.
But on the actual device, I can't seem to be able to manage to connect : the requests to /ws/app/{appID}/connect fail (with an actual appID of course) as if there would be no server.
Is the Convergence API available for my TV ? (there does not seem to have a compatibility list anywhere) Is there a way to upgrade to a 2012 platform if it is indeed a 2011 one ?
Can we test that API on a simulator ? My simulator runs under Windows 7 in a VM on my Mac (there is not Mac version of their dev tools...)
Is there really anything I can do to have a more precise diagnostic ? like logs from the appilcation running on the TV ?
Thanks
This Convergence page sounds like existence of MultiScreenService UPnP service equals the capability of Convergence API calls. So if you say "UPnP discovery works great" (given that you do an ST-limited M-SEARCH per example, not an unrestricted UPnP discovery), it should mean that your particular TV supports Convergence. Have you tried querying the TV simply with telnet? Are you sure about the port number on which the TV listens? Here the doc claims that it should be 80 for the TV and 8008 for the simulator, but i for one am very interested in the UPnP description.xml served by the TV for MultiScreenService. You could even discover some UPnP functions for diagnostic there...
Disclaimer: i have no experience in Convergence, only UPnP in general and unfortunately Samsung in general too. The fact that Samsung pushes such half-baked proprietary mockup reminds me of my short bloody disgusting career as Bada developer. Only Sony can sustain pushing proprietary mockups with dignity :)
Your year model is 2011 and you can't upgrade to 2012.
2012 models uses API v3.5 and 2011 models uses API v2.5
So this what you try to do won't work at your device as Convergence API is in API v3.5.
Check this one
http://www.samsungdforum.com/Guide/View/Developer_Documentation/Samsung_SmartTV_Developer_Documentation_2.5/API_Reference/JavaScript_APIs/Interactive_API
It gives you possibility to communicate between devices, so maybe it will fit your needs.
Finishing answering my own question:
like #Dobiatowski mentions, I'm screwed for Convergence API and 2012 platform
The Interactive API's documentation is not clear, and virtually non-fonctionnal despite 3 days of my best effort. Half of the sentence in the documentation don't actually make sense.
Still did not manage to make the interactivity simulator to work, Looks like it's not possible on Win7
Basic answer is : not possible
I'm developing an iPhone application with a couple of features.
Now I need to connect to an OPC DA server but I don't want to implement OPC by my self. Does an Objective-C library even exists? or are there other possible solutions for my problem (maybe C or C++ libraries?).
So I guess you want to access OPC DA Server information from an iPhone/iPad ?
OPC DA is part of the classic OPC specification and based on Microsoft COM Technology, so this might not be so easy.
A solution could be to use an OPC UA Gateway to expose your OPC DA Server over OPC UA, then use a C/C++ SDK or write your own using OPC Foundation ANSI C Stack, to get an OPC UA Client running and accessing your information.
Guys from Unified Automation (https://www.unified-automation.com/) have done some great stuff that you might want to give a look.
well i don't know if exist any library for Objective-C, check out in OPC Foundation or maybe you should think about develop an webapp instead a native app

I am creating the room mailbox in exchange server. and sync the exchange into iphone is also done. But how to get the rooms name and timing in iphone. is there any api or frameworks ?
Thanks
Raj
The Exchange Web Services API can be used to determine room availability:
http://msdn.microsoft.com/en-us/library/dd633709(v=exchg.80).aspx
Since it is a web service, in theory it should be caller agnostic though I don't know how authentication from the iPhone will be handled. I have only used EWS from Windows-based applications, but I know that the iPhone supports certificates and obviously it is capable of connecting to Exchange.
I am keen to get some apps built that can communicate with other devices/ web etc. i have played around with FTP and can get so far. But what is the best way to do this? We don't have any Servers with databases etc, but do have a site that we are currently uploading and downloading files to.
can anyone suggest a good/ better way to get the device to send/ receive files?
thanks
sam
If it's HTTP communication you're wanting to do, the simplest and most powerful tool is ASIHTTPRequest.
HTTP is the protocol your web browser uses to talk to web servers. If you have a site you're storing and downloading files at, it's almost certainly HTTP you're talking to it.
For iOS device to device communication one can use Bump API.
EDIT: I don't know of a generic framework for device <-> server communications, but having built applications that use web services of other providers like Yelp, Yahoo, Google Maps, I would say the way to go for this is to have REST based web services which exchange data in JSON format.
I am trying to allow people (from a URL) to connect to a calender/contacts from their iPhone, Blackbury or Android phone - what is the best way to do this?
I've had a bit of a read and it seems that CalDAV and CardDAV are the best way to integrate calenders/contacts, but how exactly can I do this? The internet seems to lack a standard way of how you can integrate this into a number of devices.
Which mobile devices support them? And is it possible to just provide a URL and then the calender/contacts just automatically sync!?
All of this assumes you have some sort of Groupware server setup somewhere which acts as the repository for this information.
For opensource you might want to look at a product called Sogo. Apple also do a caldav/carddav server written in python. They expect you to buy a mac server but you can download the code and run it from a pc or linux box. There's a heap of paid-for groupware.
You might want to check out the "opensource" client software written by the same kids who develop Sogo caled funambol. This claims to be x-mobile (all the ones youve mentioned anyway).
The idea behind all the *DAV protocols is that yes everything is done by Uri (this was actually specced by Tim Berners Lee in his draft for the web).
I've just been through this very same process and found only emerging standards, of which *DAV are the de facto ones IMO. HTC use MS active sync on my HD2 to sync my Gmail. Go figure!
Bedework is CalDAV/CardDAV server that allows you to hook your iPhone/iCal calendar and events.
I have used it and it gives you an url to sign in with in you phone calendar. The Bedework is a server you could install on you machine (it is provided with documentation; this is a good point to start with).
Android natively does not support Bedework. In order for Android to support the CalDAV you have to install an application that supports CalDAV, but I do not know if they work with Bedewrok or not.
In the case of android you could try using the CalendarProvider and the ContactProvider. You could refer to this : http://developer.android.com/guide/topics/providers/calendar-provider.html
