Universal Windows 10 SDK: Adding Flash to the Camera Sample

Its not too hard to add flash capability to the Universal Windows SDK Camera sample.  Here’s how.

Visual Studio 2015 Update 2 is now available

For those who have missed this, its at https://www.visualstudio.com/en-us/news/vs2015-update2-vs.aspx

 

I think that these two improvements are gems:

  • Universal Windows SDK Version Picker. When creating a new UWP project, you can now select the version of the Windows SDK to target as well as the minimum OS version on which the apps are to be available.
  • Debugging C++ Background Task in Universal Windows Apps. You can now debug Background task processes in a Universal Windows app in Visual Studio. You can access this option on the project Properties Debug tab.

 

PS: Has anyone tried Compact 2013 Platform Builder and App Development with this release.  Have they made it through unscathed?

I’ll try Iot-Core tomorrow.

Win 10 Phone: Universal Windows Apps Sideloading - Winappdeploycmd: (Further Updated)

In a previous blog I dicussed discussed in detail deployment of an app to a Windows 10 Phone.  One of the options, Sideloading required the winappdeploycmd tool that is installed with the Windows 10 SDK.  I suggested that maybe you could just install winappdeploycmd as its .msi installing is a separate entity in the SDK installation files.  I now have tested this.

Universal Windows Windows App: Create A Project Test Certificate

Visual Studio automatically creates a Test Certificate when the project is created. But in moving the code around, especially to and from a repository you might need to create a new one. Also, the default certificate that Visual Studio generates expires one year after the date on which the certificate was created. Before the certificate expires, you must use the App Manifest Designer to either regenerate the certificate or to create a new one. Without this you can’t create an AppX package for app installation. Here’s how to create a Test Certificate.

Unlocking a Windows Phone

I purchased some Windows 10 Phones for business use where they are to run a custom UWP business app.  Being about $100 they are quite economic but they were locked to local Telco, Optus (Australia). The Telco would give you the unlock key for $90 but I found an online site that could do it for about $20.

 

The key take home is that the instructions for implementing it as per the Telco and as per the source of the key I used, did not work for me but there is a simple method that worked for me that others had used with AT&T:

Yet another GEM: Universal Windows (10) App Settings – Solution

Universal Windows(10) Apps settings is easy. Its simple to specify as part of the build, save them to storage, get them back and modify .. I mean dead easy! Smile

Another GEM: Microsoft SQL Server Credentials for a Remote Web Service

It was simple enough to get access to a Microsoft  SQL Server from a Web Service when all were running on the same machine. You use Windows Authentication. But when the services are both running locally, with the user running a Windows 10 Universal app that calls the web service, they won’t be logged in an so the web service needs credential for the SQL service.

More GEMS: Kept getting Network Access Required in a Universal App–An hr or 2 later!

I’m creating a Windows 10 Universal Phone App that talks to a Web Service to post an entity (object) in Microsoft SQL Server running on the same machine as the Web Service. Initially did all including the app on my laptop using localhost as the network target. Solved the SQL Server credentials .. OK. But when I switch to using the laptop’s system name or its IP address (all still running on same machine) got Network Access Required error.

Little GEMS: XAML page not linked to its Codebehind Page .. Solution

 

In developing a Universal Windows app, when you add an existing XAML and its Codebehind page, they often end up unlinked in the Solution Explorer. This limits the ability to autogenrate event handlers in the codebehind page for UI elements.Spaso Lazarevic has a good solution that involves a little editing of the project file.

Win 10–IoT Core: Visual Studio 2015 Update 1 App Deployment – 3 Universal(Unencrypted Protocol)

In previous versions of IoT-Core, you just used the Authentication Mode-None when deploying and debugging an app from Visual Studio. This has changed a little so this blog is just a short note about the configuration for deploying a Universal Windows App from Visual Studio to an Windows 10 IoT-Core device.
