Facebook headchat for windows 8.1 - windows

I m starting to create an windows 8.1 app with visual studio 13'.
My idea is to create a simple login fb form - simple list with online/ offline friends and heads like android os when chatting with someone.
A very simple image how i dream it: http://img.prntscr.com/img?url=http://i.imgur.com/plb2mXc.png .
My questions are:
1) Can i keep going with this idea? I mean: Can i have permissions which i need from facebook sdk- api?
2) Heads must be create like widgets or i have to create a bar on which leans heads chat?
Thank in advanced!!!

Since friend permissions are gone (that would include the friends_online_presence permission), there is no way to build this. Check out the changelog for more information: https://developers.facebook.com/docs/apps/changelog

How do I sync a Slack workspace from mobile to desktop?

I was added to a Slack workspace by a coworker. I must've accepted something on the mobile app because I have access to the workspace there. Somehow, the desktop app never reflected this change and shows no sign of knowing about the workspace. I attempted to solve this problem by inviting myself to the workspace from the mobile app and accepting the invite link on the desktop app. I now have access to the workspace on the desktop app, but no direct messages have been carried over. (My desktop is Debian and mobile is iOS, if that makes any difference.)
I can't find any discussion about this on the Slack website or through a DuckDuckGo search... Does anyone know how to sync Slack from mobile to desktop? I will greatly appreciate any suggestions or direction. Thank you in advance!
This is not possible and despite the fact that this question was raised as soon people had two devices, Slack never agreed to address it.
On desktop I have no less than 15 workspaces.
A workaround that just worked for me was signing out of the desktop app and signing again. That allowed me see all the workspaces I was already in.
Here's a workaround (it is not ideal so I'm still searching for a better solution):
From the channel(s) I wanted to sync, on the mobile app, I added myself and now I have access to those channels on the desktop app. Unfortunately, I show up as two members with the same name...
I know this is an old thread, but I was struggling just now with the opposite problem: there was a Slack workspace that I could see in my computer but not in my mobile app. I write here how I solved it in case someone faces the same problem in the future.
In my case, it turned out that the problem was that I was using different email addresses for the different workspaces (either my professional or personal email), and I had pending to verify one of the addresses.
To solve it I:
Opened the Home menu by either sweeping right of tapping on the icon of the workspace I was in at that time
Went to Add a workspace
Saw that there was one email pending to confirm, so I confirmed it and immediately saw the missing workspace in my home menu together with the rest

Sharing something in Social Media in WP7

I want to implement a share option in my app which will allow user to share something or say post something to his linked account(like facebook, twitter, linkedin etc). But i am not getting any clue. I read somewhere that in WindowsPhoneTool71 the share property is inbuilt, but I am using WindowsPhoneTool7. So anybody out there to help me out.
Thanks!!
Why are you using WP7 rather than WP7.1? The Mango release was rolled out months ago, so you can guarantee that any Windows Phone 7 user will certainly have had the update by now. With Windows Phone 7.1 the ShareStatusTask will do exactly what you want in just lines of code!
ShareStatusTask task = new ShareStatusTask();
task.Status = "User Status";
task.Show();

Windows Phone 7, get apps list + screenshots

is there any chance, that (after mango is released) the third-party WP7 application can retrieve list of already installed applications ?
Is there possibility to create an application which will take screenshot on background. For example screenshot of mobile main applications list every XY seconds/minutes. I´d like to parse installed applications from that screenshot if point 1 is not possible.
Thanks for your answers...
No, there is not
No, the only way to create WP7 screenshots is from the emulator or with special engineering devices that only MS has

admob wp7 sdk dont work, alternative ad networks?

i use the admob wp7 sdk for displaying adds in my apps, but i dont see any, it looke like:
<google:BannerAd
xmlns:google="clr-namespace:Google.AdMob.Ads.WindowsPhone7.WPF;assembly=Google.AdMob.Ads.WindowsPhone7"
AdUnitID="MY_AD_UNIT_ID">
of course i insert my adUnitID, when i start my app i dont get anything to see, also when i enable test mode i cant see anything, what could be worng? on the homepage i see that i got requests because it counts up, but nothing to see.
other question:
are there any other add providers instead of smaato and adDuplex which provide a WP7 sdk?
As of today the Microsoft Ad SDK for WP7 can now be used in all territories where the marketplace is available.
Alternatively you could consider AdDuplex
I would recommend looking at the documentation and contacting admob support. Its a third party control so you would be lucky to find someone on here who can offer advice.

Loading Xbox Live Avatar Model in Windows Phone 7 using XNA

Does anybody know how to access the Xbox Live Avatar from within an XNA based Windows Phone 7 application?
Examples I have found seem to use a SignedInGamer.Avatar property, but this is not accessible from Windows Phone 7.
Is there another way or is this not possible in the first place?
as a side note, I'm using the recent Mango beta 7.1 SDK
Thanks!
It's not available in code unless you have the elevated privileges of access to XBox live.
You can, however get an image of your avatar from the web. try:
http://avatar.xboxlive.com/avatar/XXXXXXX/avatar-body.png
where xxxxx is the XBox account name. e.g. http://avatar.xboxlive.com/avatar/kris/avatar-body.png
My understanding is they are only available to partners. See this post for more information:

However, it looks like you can demo them, here's a quick tutorial on using them:
