I cannot open the bluetoothadvertisement Solution (cs). I receive a message that "bluetoothadvertisement.csproj" and "tasks.csproj" are not compatible with my Visual Studio version. I just downloaded the last community version of Visual Studio 2015.

Any idea why I have problems with the bluetoothadvertisement sample?

I'm using Windows 10 Build 10130 which is running as a virtual machine.

I was looking over the Pull To Refresh sample and had a couple of questions:

1.) I noticed that you put the ListView inside a ScrollViewer. I was under the impression that it shouldn't be done, because it would prevent virtualization. Is that not the case?

2.) I am able to get the pull to refresh to work with my touch screen, but is there any way to get it to work with a mouse?

After clicking navigation menu list item many times, the memory raised and never decreased(wait 20 minutes). I don't think enable navigation cache is good idea, because it only decrease the times of create new page instances. I just don't know how to dispose the no used pages? Does anyone can help me ?

Exeption:
"Access is denied. Your App does not have permission to use Bluetooth in the background. Make sure you have declared the Task Type 'bluetooth' in your manifest."

This exeption was trow for BluetoothAdvertisement SampleProject, same for my testProject.

Hi,

For a week or two now, namespace "Windows" is not recognised with my universal windows hosted apps.
Please find the screenshot of what's going on when i press F12:

Was perfectly working before and as you can see, next to "undefined" the rest is recognised but I cannot use the windows API within my hosted app because (typeof Windows) always returns "undefined".

Do you know why suddenly, all calls to "Windows" return first "undefined"?

Thanks

I launch sample:

• socketactivitystreamsocket on desktop
• socketactivitystreamsocket on my Lumia with windows 10

Initially, all works fine.
Then I lock screen and wait for 8 minutes and send a message - nothing happened.
I send a message again. And see the message on server side "An existing connection was forcibly closed by remote host. (Exception from HRESULT: 0x80072746)"

Log of my actions:

9.44 - send messages all works fine even on lock screen
9.44 - lock screen
9.52 - send message nothing
9.52 - send message nothing
9.52 - An existing connection was forcibly closed by the remote host.
9.53 - Client connected message in server app
9.54 - Send message nothing
9.54 - Send message
9.54 - An existing connection was forcibly closed by the remote host. (Exception from HRESULT: 0x80072746)
9.56 - unlock the phone - no any message after 9.44

Nice start. Basic navigation on the samples i have tried appears to have the same flaw. Using Lumia 630 with latest build from the week of 5/5/2015. The flaws are as follow, back button no longer navigates between pages on phone, i understand that there is no back button on the desktop/tablet but it breaks a consistant feature of Windows phone from 7.0

Second, when starting the any app, pressing the link such as 1) Do this, . the pages disappears, i have to recall it by the hamburger menu then it works fine. I will have a look at these in the next couple of days.

Is there going to be a forum/discussion area on app design? I noticed in the latest release, the sizes of the tiles have changed slightly of the start page.

Press on the hamburger menu, it asserts out:
Exception = {"The text associated with this error code could not be found.\r\n\r\nA TargetPropertyPath for a Style Setter cannot specify an explicit Target object. [Line: 55 Position: 49]"}

In the WebAccountManagement sample, the scenario "login with default Microsoft Account" seems to login ok, but the webAccount.userName is always null.
Also, when,extending the scope with wl.emails in,addition,to wl.basics, no emails information is available.
Would This ne because I run,the code from a Windows 10 build 10240 included in,a,professional domain ? Or is This due to annoter reason ?

Please provide samples on how to create Alarms and Reminders with Windows 10 API. Nothing can be found on the Internet.

Hi,

I have updated my phone to the latest WIndow 10 build for Windows Phone. When I build the "bluetoothadvertismentsample" I get the following exception:

{System.UnauthorizedAccessException: Access is denied.

Your App does not have permission to use Bluetooth in the background. Make sure you have declared the Task Type 'bluetooth' in your manifest.

at System.Threading.WinRTSynchronizationContext.Invoker.InvokeCore()}

I have attached a screenshot that clearly shows that the Task-Type was added by the creator of the sample.

Any ideas how to fix this?

I see only one commit and my forked does not look anything like this one now... I'm no git expert so I don't know if there's anything I can do to catch up. My forked repo says I'm 118 commits ahead of Microsoft master... how is that even possible?

I'm lost here

Running against WP Emulator works though.

The result is always false.

Are there any examples that use the hardware back button on windows mobile and the back button in tablet mode?

The BackgroundAudio is pretty nice :-). But I miss some sample how to enable the controls to change track and pause in the taskbar when you hovering the icon. Currently they are just disabled. I thought this would be solved by using SystemMediaTransportControls which the sample use. But it seems to just work with the controls on the keyboard, not the task bar.

Project: speechandtts
Phone: Lumia 920

Exception 0x80050022 occurred on creating SpeechRecognizer.
Also there is no prompt to request permissions.

How can I open this project ?

The Hamburger-Button overlay the title. After a toggle of the button the bug is gone.

The JS samples all appear to use a build of WinJS 4.0 other than what was shipped with the VS2015 RC. This makes it very difficult to grab the code and toss it in a new JS UWP app without downgrading WinJS.

I tried to scenario-2 of Bluetooth Advertisement Watcher and Publisher sample app, but that couldn't be detected by other iBeacon-Applications on android or iPad.
I changed manufacturerData.CompanyId at the sample app's code, but I got same result.
Is there other necessary source cord change?

By the way, the watcher (scenario-1) can be received the advertise message of iBeacon and BLE Beacon.

I've only been able to get cortana to work with this app once. Cortana doesn't provide the commands that are installed under the "?" menu. Uninstalled/Reinstalled and though the commands show in the help menu - after typing them in the ask me anything box, then only "bing search" is an option.

Whats the right way of tickling it to make it work?

Hi,
are there any plans to add js versions for the video playback samples?

Thanks,

I downloaded the examples yesterday (Sunday august 2) and tried Two of them(SerialArduino and WebView) and both give Lots of errors. SerialArduino gives 1816 and WebView 84 errors.
The most significant error is: Error CS0246 The type or namespace name 'System' could not be found in .NETCore,Version=v5.0.AssemblyAttributes.cs.
I am using visual studio 2015 C# on windows 10, targeting x86 debugging on local machine.

in the ControlInfoData.json about the Hambuger pattern the link is "Title": "Hamburger pattern", "Uri": "https://github.com/Microsoft/Windows-universal-samples" }. I do not think that explains anything about the Hamburger pattern, if there is a link about this, is interesting to update to the right link

It would be great to see a sample demonstrating the new ValidationErrors property along with its companion properties ValidationState, ValidationIndicatorStyle & IsValidationIndicatorEnabled.

It would also be good to see how it integrates with ValidationAttribute and IValidatableObject.

Hi team,

1. After review notice that code contain -webkit -moz prefixes. I don't understand why it needed for win applications.
2. If it for reuse same code for web may be will be useful to do tool for build app oriented for web and app oriented for win app. It can be i don't know similar to postcss with extensions or plugins for it.

PS: if it possible can show where i can ask question like "How it can be ... la la la ?". Because after some hours i didn't understand where place where can i ask it.

Sorry for strange question but it really not useful.

Thank you.

I should clarify, it is on the state triggers Readme: https://github.com/Microsoft/Windows-universal-samples/tree/master/xaml_statetriggers

Link to Sample 1 is 404

The following files are missing in the WebView sample (though they show up on the project)
winrttoastnotificationwrapper.cpp
winrttoastnotificationwrapper.h
winrtsharedobject.h
winrtsharedobject.cpp

In Build 2015 there was a session about accessing/managing user data (emails, contacts, appointment) - https://channel9.msdn.com/Events/Build/2015/2-684 .

I don't find examples for those API, i'm interested also in background task triggers for tracking those data.

I want to run the sample from above and get a Access to name disabled by Privacy Settings or Group Policy.
How can I check them both? I have enabled Account Info under privacy settings

I am trying to connect two devices via WiFi direct using the Sample WiFi direct code. One device is a surface 3 running Windows 10 and the other is a Samsung tablet (also tried tv) running android (the Samsung devices can easily connect with each other, so I know it is not the hardware). For the two primary devices, they are able to see each other to connect. I am sending a connection request from the Samsung to the Windows 10 device. The below code gives the error:

Connect operation failed: AsyncBehaviorError: Status is 'error', but getResults did not return an error

My impression is that this line is run but then fails to continue Windows.Devices.WiFiDirect.WiFiDirectDevice.fromIdAsync(deviceId, connectionParams).then(

The relevant code is below:

function OnConnectionRequested(e) {
               var connectionRequest = e.getConnectionRequest();

        WinJS.log && WinJS.log("Connecting to " + connectionRequest.deviceInformation.name + "...", "sample", "status");

        var connectionParams = new Windows.Devices.WiFiDirect.WiFiDirectConnectionParameters();
        connectionParams.groupOwnerIntent = parseInt(txtGOIntent.value.toString());

        var deviceId = connectionRequest.deviceInformation.id;

// device id comes back equaling: "WiFiDirect#26:4B:03:36:49:C6_PendingRequest"

       Windows.Devices.WiFiDirect.WiFiDirectDevice.fromIdAsync(deviceId).then(
    function (wfdDevice) {
        //this code never gets run
    },
    function (err) {
        WinJS.log && WinJS.log("Connect operation failed: " + err.toString(), "sample", "error");
        return;
    });
    }'

My best guess is that there is something wrong with the format of the id of the device and/or completing the call for fromIdAsync. However when I put the line regarding fromIdAsync and store it in a variable, it returns an object, meaning it is not null. One additional point is that I have tried passing all values 0-7 to account for different device types https://msdn.microsoft.com/en-us/library/windows/apps/windows.devices.enumeration.deviceinformationkind such as Windows.Devices.WiFiDirect.WiFiDirectDevice.fromIdAsync(deviceId, connectionParams, 0)

I am at a loss on how to debug this anymore.

However, of the 100 or so times I have tried, it worked for like 3 in the row, but stopped working when I restarted the program. Any help would be greatly appreciated.

It would be nice to have an example of VOIP application for Windows Universal App Platform. I expect it has some differences from regular apps (like in WP8). So it would be nice to have a dedicated example of VOIP app.

Hello,

I am unable to open a lot of the projects included here with Visual Studio 2015 (build 10074) using the RC version of Visual Studio 2015 Enterprise. Do I need to do anything else?

It would be nice to have an example of VOIP application for Windows Universal App Platform. I expect it has some differences from regular apps (like in WP8). So it would be nice to have a dedicated example of VOIP app.
UPD: Is it even possible to create VOIP app using universal app platform which have comparable functionality to WP8 Silverlight?

Hello there

I was trying to build and run the AppServices sample but it seems NuGet is unable to fetch the required packages to compile the solution. Build log here: https://gist.github.com/tiagomargalho/01a1fd552a12b15e9a86

I'm running VS 2015 RTM, NuGet 3.1.60724.766 and Visual Studio Tools for Universal Apps 14.0.23121.

Is this something I can somehow fix?
Thanks!

Will there be javascript samples for the new Win 10 map control? Everything I've seen in the samples and elsewhere is specific to C#/XAML. Will the updated map control be supported in javascript apps?

Not sure if this is just a bug with the beta. Run the app and press an arrow key. FocusManager.TryMoveFocus throws an exception -- 'System.ArgumentException'
