问题 I'm developing a UWP app with Visual Studio 2015, and one of the things I want to do use some sample data at design time.

问题 I've created my first UWP app. It's a Windows 8.1 UWP app which will help with scheduling courses at my university who's current system is awful. I've been working on it with my Windows 10 desktop computer with a 1080p monitor at default system scaling (100%). I deployed a test build and installed it on my laptop. The laptop is also Windows 10 and 1080p but has a smaller screen so I have system scaling set to 125%. My problem is that instead of this higher scaling factor making my app have

由 好久不见. 提交于 2019-12-07 08:49:03
问题 Universal Windows Platform app with Visual Studio 2015 (RTM) I have a DataTemplate that is used in multiple pages of my app, so I'd prefer to write it once and access it from anywhere I need to. In order to make it accessible by any page, I write it in my App.xaml 's <Application.Resources> : <Application x:Class="MyApp.App" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="using:MyApp" xmlns:viewmodels="using

SerialDevice.FromIdAsync() yields a null serial port

由 人走茶凉 提交于 2019-12-07 08:43:55
问题 I have something strange happening with my code when trying to connect to a serial port. When using Serial Sample, everything works just fine and it connects on the first try. However, with my code the serial port returns a null. I have found a workaround by nested the call to write the serial port in a do loop until the serial port is no longer null and it works. It takes, on average, 500 loops to connect and it has always connected. I know it's dangerous because there is the infinite loop

Bitmap smoothing in UWP

由 末鹿安然 提交于 2019-12-07 08:06:07
问题 I am trying to figure out how to resize an image without losing quality in UWP. I know in WPF there's an option to smooth an image using this: RenderOptions.BitmapScalingMode="HighQuality" but I can't seem to find an equivalent in UWP. Here's what the image looks like: And what it's supposed to look like: If you look closely, you can see that the picture is badly pixelated. How can I achieve this in UWP? I'm resizing it by XAML (circle crop): <Ellipse x:Name="personImageContainer" Width="50"

How to debug an UWP app in Release mode + “.Net Native tool chain”

由 走远了吗. 提交于 2019-12-07 07:58:54
问题 I have developed an UWP app that works globally fine, but I encounter some problems with the Store app, or with the Release build, whereas all works fine in Debug build... The app seems very basic: ts allows users to create and sync forms through webservices. At the launch of the app, a test is done to see if a user is already logged in: if it's not the case, the app navigates to the " Login " page, otherwise it navigates to the " Home " page, which contains the forms list. Then the user can
