Integrate existing VB database with windows store app

Hi
Can I integrate a VB Database Access 2007 with a Windows 2008 store app?
If yes, can I have a hyperlink that retrieves a search inside this database and goes directly to a page created by this database?
Imagine that I have an e-book with a table of contents where I have several hyperlinks for a query that shows me a specific poem and image inside a page.
Is there a sample?
thanks

Hi Rui - there are no APIs that will connect to an Access database directly within a Windows Store app. You can convert the database to SQLite, or provide a web-based interface to the Access database in order to retrieve/update the data.

How to use local .sdf database in a windows store apps

Hi,
I am new in windows store app development. I have been working in WPF application development for long time. Now I want develop windows store apps. I am studying on it. I got a problem. I what to store data from windows store app in .sdf database file. I
confused is .sdf database is compatible with windows store apps.
I want Deploy the apps in windows apps store. Is .sdf database support in client machine while he download it and run his own machine.
Please Suggest me about it with sample reference. It will be very helpful for me.

SDF files are used by Microsoft SQL Server Compact Edition. SQL CE is not supported for Windows Store Apps/Universal Apps. Only WP Silverlight Apps can use SQL CE. You will have to switch to a different database format.
As far as I know the only DB currently supported for local deployment with Windows Store Apps is SQLite.

How to use offline map for windows store app using c# and xaml

Hi friends,
I want to integrate offline map in my windows store app but I am not able to achieve that.
Below is my requirement:
When a user wants to go somewhere where she/he doesn't want to use wi-fi or mobile data but wants to use map to assist her/him to roam around. For this I want to give an option to download the map for that region/area before leaving for that place and there
she/he can use map even in offline.
Is it possible that I can achieve this using Bing maps?
If yes then tell me the processes to follow.
If no then can I achieve this using "Here" or by using any other API or by tweaking any way?
Note: I am showing maps in case of online and user can search for directions or any places in that. I am using Bing maps for that.
Thanks,
S.Sandeep

Hi Sandeepmsandy,
There is no available code sample for this scenario. You may write your own.
Step 1: Get pdf URL from sqlite database. Please refer to the following MSDN blog and see a code sample.
http://blogs.msdn.com/b/robertgreen/archive/2012/11/13/using-sqlite-in-windows-store-apps.aspx. Note, you need to retarget the project to 8.1 and then get two sqlite packages from NuGet before building this sample.
Step 2: Use some special classes to get file from serer.
HttpWebRequest can help download small pdf files. For more information to see
https://social.msdn.microsoft.com/Forums/windowsapps/en-US/de96a61c-e089-4595-8349-612be5d23ee6/download-file-with-httpwebrequest?forum=winappswithcsharp. It’s easy for use, but if you want to download the larger or many files, it’s recommend to use
BackgroundTransfer namespace. The classes in this namespace provide a power way to transfer files in the background. See a code sample from MSND.

Login to WebApi (MVC + WebApi) with Microsoft Account from Windows Store App

Hi
How can I access a WebApi Controller (ASP.NET MVC+WebApi) that is secured with Microsoft Account from a Windows Store App?
I have no idea how to login. I tried the LiveSDK but this gives me only access to OneDrive, Callender and so on.
Could someone please point me in the right direction.
Thanks
Guenter

Hi Guenter,
To be clear, you are using Microsoft account as login and at same time you have your own REST service for other functionalities?
Let's say if you login with LiveSDk, you should be able to get some access token, see this for more information:
Signing users in, after that use the token to access your REST service, as I understand REST service is a kind of http request, we can use HTTPClient to request data from the address.
I'm afraid there is no existing sample here but the only thing I found is HTTPClient sample:
https://code.msdn.microsoft.com/windowsapps/HttpClient-sample-55700664, you can use POST to send your token information to the server.

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

How to display the PPT, PDF, XL, DOC files with in the Windows store app?

Hi,
I would like to display the PPT, PDF, XL, DOC files with in the Windows store app? is there any controls provided by Microsoft to view these files with in the app?
Or
Any workaround to achieve the desired functionality?
Kindly provide your inputs if any one has.
Regards
Prasad

Hi Prasad,
As I know currently there is no in-build functionality to display the PPT, XLS or DOC file directly on the Windows Store App, but you can always open these files by
Launcher class
However a good news is we can display PDF on Windows Store App by
Windows.Data.Pdf class, see this for more information:

Consuming live streaming in Windows Store app with C#

I need to know how can I use a URL for camera live streaming. The camera is located in a remote place and used in a radar on the street. I don't know in fact how to consume the live streaming of this camera?
Ahmed Abd El-Karim

Hi Ahmed,
Real Time Messaging Protocol seems what you need, the URL could be start with "rtmp://".
However we do not have this supported in Windows Store App, if you need this functionality, probably you may need write your own code. See more information from:

Distributing multiple versions of an app within a single Windows Store app

The company I work for creates Point Of Sale (POS) software using Software As A Service (SAAS), so we host our clients' databases. We do not force all of our clients to all be on the same version of our software; i.e. some clients are on version 3,
others v4, others v5, etc. As you would expect, the database schema for each of these versions is different, so each of these clients also use a different version of our client-side app.
We are looking at making a Windows Store app that acts as a light-weight POS app that clients can use to sell their products. The problem is, we will require having multiple versions of our Windows Store app in production; the version of the app that
the client uses must correspond to their database version. We were initially hoping to have our Windows Store app detect which version of the app the client should be using, and then automatically update itself to the correct version, but
were told on this post that it violates the Windows Store certification criteria, so that's not an option.
It has been suggested that we put multiple apps into the Store; one for each version of our software. We really don't want to do this though, as when we upgrade a client's database from one version to the next it would require that they uninstall their current
app and install the newer versions app, causing them to lose all of their custom settings. We would like the updates to remain as transparent to the end users as possible; the store clerk shouldn't need to worry about which version their database is on so
they know which app to download from the Store.
As a possible workaround, is it ok for us to package all 3 versions of our app into a single Windows Store app, and then just have the app check at runtime which version it should run? I assume that this is alright, since we will not be downloading
any other code or installing any software/apps, as was the case with our original solution that violates the certification criteria. Essentially we would just have 3 different classes and determine at run-time which classes code we should run.
I know that this solution isn't ideal, as it means our app will be 3 times larger than it needs to be, and that an update to any one of the 3 versions of our software will require an update to the Store app (so potentially users may download a new version
of the Store app, even though it doesn't have any changes for the particular code version (i.e. class) that they will use), but it's one of the best alternatives we have come up with. I just want to check that this solution doesn't also violate any certification
criteria before we go down this road.
If this is not allowed then our only other alternative might be to go with sideloading (as
I discuss on this thread) and avoid using the Windows Store all together, but we would prefer to use the Store if possible as it eliminates a lot of overhead that we would have to deal with if we use sideloading.
Any insights or suggestions that you can give are appreciated. Thanks!

Hey Mr_bigworlds, thanks for the reply. The moderator on this post actually told me that this
would be a better forum for my inquiries. I agree that there may be another forum better suited for this question (there are so many that I don't know about), but since this relates to Windows Store certification criteria, I don't think the Windows Desktop
Development forums are the place for it.

Trigger Windows Store Apps update by script at first login

Hi
Is it possible to trigger Windows 8.1 to check for Windows Store Apps updates at first login?
My issue is that when I add language packs to my Windows 8.1 images, the default apps (Mail, Calendar, Food and Drinks) are still in English. Not until the Windows Store apps are updated will they change to the correct language (Language of the
OS). I have turned on autodownload in the registry using this registry key:
REG ADD "HKLM\Software\Microsoft\Windows\CurrentVersion\WindowsStore\WindowsUpdate" /v "AutoDownload" /t REG_DWORD /d 4 /f
It seems kind of random how long it takes before the autodownload kicks in. Some times it just a reboot and other times it takes like 24 hours. Can I trigger this update to start with some kind of script?

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.

Tabbed page in a Windows Store App

I am creating a Windows 8.1 app (Windows Store App) and I need to have a tab-based page in this app. As an example, for adding a new contact, I need to group the new contact details in tabs which can be switched from the left side
menu items.
I tried to use a FlipView for this purpose but I don't want the users to be able to switch between pages by flipping. I want to create a page similar to
[Add a recipe] page in Microsoft Food & Drink app.
How can I do this?

You can create a Page that contains a
Frame and switch out the frame as each menu item is clicked.

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
