uwp

My UWP needs to load a file and I want to know: Where to put this file, in the package installation folder or the application data folder? How to deploy this file to the folder I want when I deploy my app using VS 2015? You can add files either as resources or content files to your project. If the file is something like a Image, SQLite Database or text file, the best approach will be the Content build action. You can then access the file using StorageFile.GetFromApplicationUriAsync : var storeLogoFile = StorageFile.GetFromApplicationUriAsync( new Uri( "ms-appx:///Assets/StoreLogo.png" ) ); You

I'm working with UWP and trying to make the app with a trial version (1 month) and products purchase that make full version with expiration (1 month and 1 year). The general idea is, when the user downloads for first time the app, he has a trial period of 1 month with ads. After the month of trial version the app asks that need to buy a product with a periord of time and with this remove adds. The problem is that I don't know how to make at same time the buy of full version and product expiration, or make the full version with expiration.

I made a C# executable which make a test folder and copy test.txt file from it's execution folder to AppData folder. Here is my code: static void Main() { string fullPath = $"{Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData)}\\test"; string destination = $"{fullPath}\\test.txt"; Directory.CreateDirectory(fullPath); string location = System.Reflection.Assembly.GetExecutingAssembly().Location; int index = location.LastIndexOf("\\"); string source = $"{location.Substring(0, index)}\\test.txt"; File.Copy(source, destination); } Then I make appxmanifest.xml file using the

How do you get the currently highlighted/selected node from a TreeView control? Based on the documentation here it should be possible to iterate through the control's SelectedNodes property but its always empty. EDIT: This turns out to be an actual bug with XAML, tracked here . Until it's fixed, the accepted answer does fine as work-around. Context: I'm working on a simple demo application to explore the TreeView control. I'm trying to add a keyboard shortcut to delete the currently active/selected node. I have the delete functionality in a RelayCommand class that implements ICommand . I have

I am new to T10 and trying to learn it. This is a follow-up to Template 10 Multiple Windows In 'regular' (meaning non-Template10) UWP app I've learned to do something like this (as a short example) in order to support multiple views: public App() { InitializeComponent(); Suspending += OnSuspending; } readonly List<CoreDispatcher> _dispatchers = new List<CoreDispatcher>(); protected override async void OnLaunched(LaunchActivatedEventArgs e) { Frame rootFrame = Window.Current.Content as Frame; if (rootFrame == null) { rootFrame = new Frame(); rootFrame.NavigationFailed += OnNavigationFailed;

So HoloLens is stupid in that it only recognizes one FilePicker at a time (no matter how many may be installed). I don't believe the developers are going to try making multiple filepickers work. So, I'm trying to figure out my own filepicker in an attempt to be a proxy-select for other filepickers. In essence, I want to make a filepicker chooser that appears as a typical filepicker (if that makes sense). Trouble is, it doesn't appear possible to get a list of pickers installed! Am I experiencing a pipe dream, or is there a way to invoke a picker from a list of pickers? For the moment this is a
