Windows Store App can't verify the server is trusted for your sign in address

I am aware this is (or was) an issue for the Lync 2013 client as well, as per
http://terenceluk.blogspot.ie/2013/04/signing-into-lync-2013-client-presents.html
This does seem to be fixed at this stage though, because after adding lyncdiscoverinternal.SIPdomain.com the Lync 2013 client does not prompt about the certificate.
However, the Windows Store app does prompt "Lync can't verify that the server is trusted for your sign-in address. Connect anyway?" This presumably boils down to the same issue where our Lync 2013 Frontend is lyncfrontend.internal.domain.com which
does not match the SIPdomain.com.
Is there a fix for this other than forcing lyncdiscoverinternal to the reverse proxy? The TrustModelData registry key only applies to the Lync 2013 full client so does not affect the Windows Store app.
Any suggestions would be welcome.

Hi wagenveld，
Create the DNS records as below:
Internal SIPdomain.com zone:
DNS A record：
lyncdiscoverinternal.SIPdomain.com-> sip.SIPdomain.com
DNS A record:
sip.SIPdomain.com-> IP address of Front End Server
For details, you can refer to the following blog:

How to distribute my windows phone 8 app and windows store app without publishing in the store

How to distribute my windows phone 8 app and windows store app without publishing in the store
any business license or enterprise license needed..
I am a windows developer talking behalf of my company i.e wipro
I have a question about the enterprise license and we are building an app for the limited users i.e our company employees and users and we do not want to publish in the store
How to release the app?
what are licenses etc needed?

Hi,
for developers distributing apps without Publishing in the Store, the sideloding Enterprise key license through volume licensing is required.
Starting May 1, 2014, customers who want to enable sideloading will be able to purchase an Enterprise Sideloading key for $100 through the Open License program.
An unlimited number of devices can be enabled for sideloading using this key.

I've just redeemed a $25 gift card but when the process was completed, the previous credit I had on my account (about $3) had disappeared and the total credit I now have is only $25. How can I retreive the $3? Thanks for your help.

Is Windows store app can hold 500 pages?

I want to create a game with 500 level each level written in every page, so i need 500 pages. Is windows app can hold 500 pages in one project?I just remove backStack to optimize the app. I am just absolute beginner sorry for that.

That sounds like a really bad design to me.
Can you not dynamically fill the page with your "level" instead when the page is navigated to? Use a Canvas or other control (as your level needs) and then use a proper class in code-behind to put the current level data to the page?
Use the same page every time. When the user has to go to the next "level", just change the level to the new one and re-populate the page.
There are other things to think about when asking "can I have 500 pages..." such as how you'd recover from a tombstoning event such as being navigated away from. How would you get the user back to the 433 page quickly, as an example?
Also - If you wanted to add a new feature to each page, you'll have to go and do it 500 times.
And - If you want to move your project to another platform now or in the future, how long will it take to re-create 500 pages?

How can we get a url for a "Meet Now" conference call from within the Windows Store App?

Hi,
Is it possible to get the url for the current meeting / new "Meet Now" call from within the Windows Store app?
You have the option of inviting your current Lync contacts, but I don't see a way of giving a URL to clients that would launch Lync on their device, or take them to the web app.
I can see how to get the link using the Outlook plugin, for pre-scheduled meetings. Is this link always the same and the one that should be used for an impromptu "Meet Now" meeting? It would still be good to know how to get this URL from within
the store app so I can tell clients where to get it.
Some people may be on Windows RT devices and not have access to the plugin in Outlook, and want to start a meeting at short notice and then invite others via email or pasting a link to them elsewhere.
Any help appreciated.
If I have answered your question, please mark it as the correct answer. If I have provided helpful information, please mark it as so.

Hi,
Agree with Holger, I check on my Lync Windows Store app and can't find the meeting URL as well.

Windows Store apps on Windows Server 2012 with XenApp?

We've got asked by a vendor whether our app will be able to support multiple simultaneous users, when installed on Windows Server 2012 and accessed via XenApp.
I suppose the real question here is whether or not Windows Store apps can be run in XenApp over Windows Server 2012 at all, and if so whether there are any special requirements on the apps to support multiple simultaneous instances execution.
The app itself takes each user through a log in procedure, during which all the dynamic user-specific data is retrieved from the back-end server; no such data is stored by the app locally.
Any advice will be greatly appreciated!
Thank you,
Alex

System.ExecutionEngineException in a Windows Store App? - Why?

Hoping for some help from the powers that be or other resident experts, as I think this is one tricky problem.
I'm getting some seemingly random System.ExecutionEngineException events in my Windows Store app. Even though the error message itself is less than useless, when enabling native code debugging there does seem to be a connection to the use of streams and
possibly thread blocking. The call stack almost always contains a reference to SHCreateStreamOnFileW or similar stream-related functions (although that particular call is unsupported in WinRT, I'm assuming the kernel is calling it under the hood; I certainly
am not). In my own code, I do indeed utilize CreateStreamOverRandomAccessStream though so there's an obvious possible connection there.
I cut back on what was probably overly conservative use of EnterCriticalSection calls and that seems to have eliminated *almost* - but not all - of these insidious errors. Therefore I'm wondering if there's a connection between these errors and possible
thread blocking or competing locks? They also definitely seem to occur only when disk access is sluggish. So again, I'm thinking some issue with thread blocking while waiting for the disk. But just a guess.
What's particularly confusing is that the docs say this exception is obsolete, so I don't understand why I'd be getting it in a Windows store app.
Any insight would be appreciated!
Thanks,
Peter

You know what? I was just telling one of my testers today that I've only ever had an issue on my one laptop and no other machines. And he's never experienced it. (Outside the dev environment if just manifests as a random app crash and he hasn't reported
anything like that). Thing is the laptop is basically fine otherwise. Certainly no random app crashes except my own app. A few other data points. It only manifests in release mode so far. I've never seen it in debug mode. (Maybe code optimization could be
contributing?) I am using a fair amount of C#/C++ interop and a lot of multithreadimg. When the crashes do occur they are always when the app is doing things that use the C++ modules and specifically they utilize COM streams (which I implement
in C# to wrap .net streams) and synchronous disk read ops. IStream specifically. But the modules are always called from worker threads. They never block the UI thread. So that shouldn't be the issue. Even if it is my environment there should be a graceful
way to handle the error. As I said other apps don't just crash. Trying to think of what other relevant information I can give without getting into gory and irrelevant detail. Again any other insights appreciated. I'll try to grab a stack history next time
it happens (I have to be in native mode debugging to get any useful info). that will reveal more. Thanks so much. Peter

[Forum FAQ] Go to Start Screen/Desktop when closing Windows Store App

After install Windows 8.1 Update 1, you will notice these things set by default even on touchscreen laptops and desktops:
Windows 8.1 now boots directly to the desktop.
Closing Windows Store Apps and go to desktop instead of Start Screen.
Besides option “When I sign in or close all apps on a screen, go to the desktop instead of Start” since Windows 8, another new option in Taskbar Properties “Show Windows Store app on taskbar” is used to control closing app behavior.
Features of "Show Windows Store app on taskbar"
When the setting is checked, all of the Windows Store apps that are currently running will display on taskbar. You can easily switch between Windows Store apps and your desktop and its applications through the taskbar. For mouse users,
you can also access the taskbar within a Windows Store app. Just move the mouse cursor to the button of the screen, the taskbar pops up.
When the setting is unchecked,
Windows Store apps have no minimize button, only Close button
Windows Store apps that are open are not visible on Taskbar
Windows Store apps can still be pinned to the taskbar
How do these two options work for closing app behavior?
Modern app and Taskbar setting
OFF
ON
Boot to desktop setting
OFF
Close goes to Start
Close reveals the app that was previously used, and eventually dead ends at the Desktop
ON
Close goes to desktop
Close reveals the app that was previously used, and eventually dead ends at the Desktop
Know why “When I sign in or close all apps on a screen, go to the desktop instead of Start” does not work when “Show Windows Store app on taskbar” is checked on
As MironV mentioned in the
thread, Windows 8.1 Update is designed to introduce a number of changes for mouse and keyboard users that would help them use and switch between Windows Store apps alongside their familiar desktop applications. A lot of these changes only made sense when
combined together, so they are toggled by one setting, which is “Show Windows Store apps on the taskbar.” This is usually enabled together with the first setting as a complimentary set of improvements for desktop users. When the setting is enabled, Windows
Store apps are intended to feel more like regular maximized applications living on the desktop, though they are full screen only. For example, when you launch apps from Start, they appear on the taskbar until they are closed. You can also minimize them or
switch between them by invoking the taskbar.
Please understand that unchecking the “When I sign in or close all apps on a screen, go to the desktop instead of Start" setting has no effect on close and minimize behavior when the “Show Windows Store apps on the taskbar” setting is checked, since
they are controlling two independent things. If you tend to use only one Windows Store app at a given time, it may seem like we’re not respecting the setting by going to the desktop.
Please click to vote if the post helps you. This can be beneficial to other community members reading the thread.

I don't know if I'm the only one, but on my desktop (using mouse and keyboard only) I like to have my Start screen as my main screen. To ensure this I made sure to uncheck the "When I sign in or close all apps on a screen, go to the desktop" box and
check the "Show Start on the display I'm using when I press the Windows Logo key" box. I also really like having the task bar appear at the bottom even when I'm using a modern app. Based on the settings I've chosen (i.e., boxes I've checked or not checked),
I would expect to be taken back to the start screen and not the desktop whenever I close an app. From what I've read from your response and from others in this thread, in order to accomplish this function (i.e., closing an app and going directly to the
start screen) I need to uncheck the "Show Windows Store apps on the taskbar" setting. By doing this I get the functionality I was looking for when the apps are closed and I get sent to the start screen. However, I am now not able to see the taskbar
when I'm in a modern app or when I'm on the start screen. This seems counterintuitive/confusing as many have mentioned. Not to mention it creates an additional step for users to get back to the Start screen.
All I want to do is (1) use my start screen as my main screen, (2) see the taskbar when running whatever app I'm using (e.g., modern), and (3) go back to my start screen (and not the desktop) when I close an app. It would only make sense that I should
get these results if I leave the "Show Windows Store apps on the taskbar" box checked and the "When I sign in or close all apps on a screen, go to the desktop instead of Start" box unchecked; but unfortunately this is NOT the case. I really hope that
an update fixing this is coming sooner rather than later because this is really annoying.

Is it possible to open Excel file in XAML Windows Store App?

Could you please help me how to implement ?

Thread response from msdn

Hi,
If you want to open an excel file by a windows store app. There is no direct API in windows store app can handle excel file. You will need to find a third party component. But
if you want to launch a file into its default handler, please see
Launcher.LaunchFileAsync API. And you can refer to the link below:
http://msdn.microsoft.com/en-us/library/windows/apps/xaml/hh779671.aspx
private async void Button_Click(object sender, RoutedEventArgs e)
StorageFolder storageFolder =
Windows.Storage.ApplicationData.Current.LocalFolder;
StorageFile file =
await storageFolder.GetFileAsync("56.xlsx");
if (file != null)
// Launch the retrieved file
var success = await Windows.System.Launcher.LaunchFileAsync(file);
if (success)
// File launched
else
// File launch failed
else
// Could not find file

Image file can't be opened by windows store app if the file is in the Ext4's external hard disk.

My question is described below:
I have two disks, external hard disk and removable disk. They are formatted with EXT4.
I put the same image in the disks, and use Ext2Fsd to mount the disks.
I open the file in win8, and it will default open by the windows store app : photos.
It will be success to open if the file is in the Ext4's removable disk.
It will be failed to open if the file is in the Ext4's external hard disk.
I don't know why it will be failed to open if the file is in the Ext4's external hard disk.
Does anyone have similar experiences?

Hi hatasum,
Thanks for posting!
Base on my experience, if installed Ext2Fsd, we can read the ext4 file system on windows system. But Which version of Ext2Fsd did you use? From my experience, Ext2Fsd is not spported fine about windows 8 version. Please refer to this software official
website (http://www.ext2fsd.com/ ) . I suggest you could post this issue to the Ext2Fsd discussion forum ( such as
http://sourceforge.net/p/ext2fsd/discussion/143329/thread/7f262ad0/ )for better help.
Thanks for your understanding.

Can I use the new Bing Maps control released in Feb 2015 in my windows store app?

Can I use the new Bing Maps control released in Feb 2015 in my windows store app? If not, will there be a release of the store app version that has all or most of the updates that are in the new map control for WPF/Silverlight?

The FEB 2015 release was for the WPF map control which is for desktop only. There is an existing Bing Maps SDK for Windows Store apps which has a lot more functionality than the WPF map control already. You can find this SDK here:
https://visualstudiogallery.msdn.microsoft.com/224eb93a-ebc4-46ba-9be7-90ee777ad9e1
You can find documentation this SDK here:
https://msdn.microsoft.com/en-us/library/hh846481.aspx
Also, I have written a free ebook on this SDK here:

How can I download the latest Microsoft Office for my Macbook Air through the App Store?

How can I download the latest Microsoft Office for my Macbook Air through the App Store?

Welcome to Apple Support Communities
Microsoft Office is not available in the App Store. Instead, you can purchase it in the Microsoft site > http://www.microsoft.com/mac
Note that there are other apps that do the same, like Apple iWork (available in the Mac App Store) or LibreOffice, open-source and free. I recommend you to give LibreOffice a try.
If you are interested in Office for Windows, you can find it in the Microsoft Store or at shops
