问题 I have a c++ dll that I want to utilize in the UWP project that I am working on. I need some assistant on how to achieve that. 回答1: C++ doesn't have a concept of "referencing DLLs". All you need to do to use them is to make sure they're copied next to your executable when you build your app. If you're using Visual Studio C# project (.csproj), add it to it as "Content" type: <ItemGroup Condition="'$(Platform)' == 'x86'"> <Content Include="$(ProjectDir)MyDLL\x86\MyDLL.dll">

问题 I am migrating my Windows Phone 8 App to Windows Universal Apps. I have created a Resource Dictionary with some values in Windows 8.1 project and included its path in App.xaml file.

问题 I am developing a Windows 10 Universal App and I have trouble getting items to populate in a ComboBox (both ComboBox items and SelectedValue) that is within a GridView DataTemplate. I don't seem to be able to find a way to do this. Here are the details: I have an object ( UserData ) that can contain multiple instances of another object ( List<VisitedCity> ).

问题 When user closes the app, I believe the OnSuspending method in App.xaml.cs is called first before termination. So, I put my code in there in order to automatically save what the user wrote in the TextBox to a .txt file called TextFile1.txt. The program runs without errors but it doesn't save the user's data to the .txt file when app is closed. Code in App.xaml.cs : private MainPage mainFrame; private async void OnSuspending(object sender, SuspendingEventArgs e) { var deferral = e

问题 Let's say I have a StackPanel (Orientation="Horizontal") with a fixed width and a variable/unknown amount of children, how do I tell all the children in XAML (not in code) to set their widths' to all be equal and fill up the entire StackPanel's width? It's easy enough to do with Grid when you know the number of children (just use ColumnDefinitions with Width="*"), but I'm not sure how to do it with panels (StackPanel, PivotHeaderPanel, etc) or lists (GridView, ListView, etc). 回答1: According

I already tryed to set "Compile with .NET Native tool chain" options in project's build settings, but the results still contains a lot of files. 回答1: Within the uwp development framework, there's no such thing as an exe file. From the MSDN:

问题 I'm developing a Windows phone 8.1 app and there's this scenario where I should open the webview for the user to enter the card details. Once the card details are entered and processed, the payment API will send the transaction details back as a POST request to the webview. I'm not able to get the POST data, tried so many methods.

问题 I have a strange issue with my C# UWP-Win10 app. When I re-size the window often or clicking a random button often (>3 times), I'm getting the error: An unhandled win32 exception occurred in bla.exe [bla-id] After closing this window the app crashes and in the output-window I get: The program '[bla-id] bla.exe' has exited with code -1073741811 (0xc000000d).

问题 In my Universal Windows App , I am subscribing to the Holding event in my ListViewItem DataTemplat e: <ListView.ItemTemplate> <DataTemplate> <Grid Holding="ListViewItem_Holding"> <FlyoutBase.AttachedFlyout> <MenuFlyout Placement="Right"> <!-- using the Click event --> <MenuFlyoutItem Text="delete" Click="DeleteProductClick" /> <MenuFlyoutItem Text="edit" /> </MenuFlyout> </FlyoutBase.AttachedFlyout> <TextBlock Text="{Binding Name}" /> </Grid> </DataTemplate> </ListView.ItemTemplate> All works

问题 The following code doesn't compile in a Windows 10 Universal App, but does in a .Net console app (both using Reflection): string objType = "MyObjType"; var a = Assembly.GetExecutingAssembly(); var newObj = a.CreateInstance(objType); It would appear that universal windows apps don't contain the method Assembly.GetExecutingAssembly() ; nor do the Assembly objects seem to contain CreateInstance . Activator.CreateInstance has 16 overloads in .Net and only 3 in A Win 10 app. I'm referencing the
