问题 I'm trying to write a class "Temperature" that handles communicating with my RaspberryPi through SPI to read some temperature data. The goal is to be able to call a GetTemp() method from outside of my Temperature class so that I can use temperature data whenever I need it in the rest of my program. My code is set up like this: public sealed class StartupTask : IBackgroundTask { private BackgroundTaskDeferral deferral; public void Run(IBackgroundTaskInstance taskInstance) { deferral =

问题 How can I maximize a window in a UWP project (not fullscreen!) using C#? I tried the method TryResizeView with the window bounds as parameters but nothing happens. Thanks 回答1: This is not possible in UWP at this time. So, I can't get you Maximize, but I can get you pretty close: var av = Windows.UI.ViewManagement.ApplicationView.GetForCurrentView(); var di = Windows.Graphics.Display.DisplayInformation.GetForCurrentView(); var bounds = av.VisibleBounds; var factor = di.RawPixelsPerViewPixel;

问题 ITNOA I want to detect airplane mode in windows phone 10 ( Universal Windows Application ) programmatically. Is there any way? thx 回答1: You can use this documentation and MobileBroadbandRadioState enum for UWP apps but it's reserved for mobile operators and you can't use it in app you want to upload to Store. First, you have to edit Package.appxmanifest file and add rescap namespace <Package xmlns="http://schemas.microsoft.com/appx/manifest/foundation/windows10" xmlns:mp="http://schemas

问题 Is there a way to use OpenCV libraries on a UWP application for Windows 10 without needing to create my own wrappers around openCV or purchasing Emgu CV wrappers? I am aware that there is Android and iOS support (as stated in their page) but no reference for UWP or Windows 8 store apps whatsoever. It just states that Windows is supported. 回答1: Yes there is, but I think it is not offical yet, or maybe not finished/tested. It is developed at Microsoft and most of it should be merged into master

问题 I've created a .resw file by following the instructions at https://docs.microsoft.com/en-us/windows/uwp/globalizing/put-ui-strings-into-resources. While the localization works fine at runtime, no text is displayed at design time. The only solution proposed so far seems to only work in windows 8.1 apps: Windows store app ResourceLoader at design time 回答1: The New Method of solution that you have mentioned also works in UWP. And it's more recommended to use Data Binding at design time. The

问题 Trying to figure out how to package the following solution with Visual Studio 2017 Desktop Bridge (Application Packaging Project): .NET Library DLL. WinForms executable referencing 1. Native C++ DLL exporting some functions used by 1 and 2 with [DllImport]. I added project 2 to Applications section of a package and buit it. In the target folder I have EXE (from project 2) and DLL (from project 1). And the question is: how to correctly add the project 3 (native c++ library) to a package? I

问题 I'm working in a UWP app in which I need to launch Microsoft Edge or Internet Explorer when the users clicks on a button. I've found that the way to do it is calling the System.Diagnostics.Process.Start() but I get: The type or namespace name 'Process' does not exist in the namespace 'System.Diagnostics' I've tried to install it with NuGet but I've gotten several Exceptions also... I've also tried using Launcher, but it hasn't done anything: await Launcher.LaunchUriAsync(new Uri("LINK"));

问题 I am using a frame to show my current page. The user can switch between two pages. I navigate to the pages via: frame.Navigate(typeof(FirstPage)); and frame.Navigate(typeof(SecondPage)); I thought that every time I switch between the pages the old page will be destoyed/unload all it's content. But looking on the memory usage, it doesn't look like it: (every time I navigate to the SecondPage I run the garbage collector so you can see when a navigation occured) Do I have to change the frame

问题 I have a class library (Imp.Dash.Cook) referenced by my main UWP app (Imp.Dash).
