问题 I'm migrating my Windows 8.1 projects to Windows 10 (Universal Windows Platform). At this moment I was stopped by ResourceDictionary changes in UWP . For simplicity: I have Windows 8.1 solution with 2 projects: App project (FooApp)+ Styles (FooStyles) project. FooApp has reference to FooStyles, and in App.xaml I have: <Application.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="ms-appx:///FooStyles/Brushes.xaml"/> </ResourceDictionary

问题 I wanted a single-row GridView that can be scrolled horizontally both with mouse and touch swipe. The GridView is to present images through binding so that a single image will be selected from an array of images. Everything works fine (binding, image selection, etc.) except that the horizontal scroll doesn't work. The XAML code is shown below. What am I missing? <GridView x:Name="IconGridView" Grid.Row="0" Margin="8,12" DataContext="{x:Bind IconManagerObj}" DoubleTapped="{x:Bind IconGridView

问题 I want my c# UWP App to support calling numbers. When I'm on W10 mobile I want it to use W10 PhoneCall API normal (this is working) Windows.ApplicationModel.Calls.PhoneCallManager.ShowPhoneCallUI(number, name); but on W10 Desktop/PC I won't have a GSM provider, so I thought, maybe use skype to call the number, the user pressed. Is that possible via UWP? Maybe similar like opening websites: await Windows.System.Launcher.LaunchUriAsync(new Uri(website)); 回答1: Yes， it's possible and you're right

问题 I am having a lot of trouble clearing the WebView cache in my UWP app. If I edit the content of a JS file linked from my HTML page, I can't get the change into my app unless I re-install the app. The static WebView.ClearTemporaryWebDataAsync() method doesn't seem to work. I have also tried adding headers to the request to disable caching: private void reloadPage() { string url = getUrl(); HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Get, new Uri(url)); request.Headers.Add(

问题 Microsoft documentation states that you can set icons using SVG vector graphics files: https://docs.microsoft.com/en-us/windows/uwp/design/style/icons However, when I try to use an svg file to set the icon, it just shows blank: <AppBarButton Label="BitmapIcon"> <AppBarButton.Icon> <BitmapIcon UriSource="ms-appx:///Svg/MyButton.svg"/> </AppBarButton.Icon> </AppBarButton> This is how I added Svg file to my project: Under project I created a Directory "Svg", and inside of Svg folder I added the

问题 I am fairly new to Xaml. I am learning UWP(Universal Windows Platform) and I have more buttons and I want to bind their Background property to a property of a ViewModel that will change during some events.

问题 I'm trying to call methods from an unmanaged dll from a C# UWP application. I do this, but pinvoking "LoadLibrary()" on the unmanaged dll so that I can use it. This all works fine in Debug mode, however in Release mode, I get a curious error: Message: Class Initialization method Tests.UnitTests.InitializeClient threw exception.
