问题 I'm new in UWP programming. And have some question. I have JSON with data (orders). There are some count of orders. I need to generate Grids with Text fields. Now I have xaml like this: <StackPanel Height="1020" Width="350" BorderBrush="#FFFDFCFC" BorderThickness="0,0,1,0"> <Grid Height="204" BorderBrush="#FFFBF8F8" BorderThickness="0,0,0,1"> <TextBlock x:Name="date1" HorizontalAlignment="Left" TextAlignment="Center" TextWrapping="Wrap" Text="" VerticalAlignment="Top" Width="350" Height="50"

问题 I am trying to figure out how to get rid of the padding below the text in a listview row: And my markup for the Listview: <ListView ItemsSource ="{Binding AllowedApplicants}" Height="250" Width="219" VerticalAlignment="Top" Grid.Row="3" Grid.Column="1" Grid.ColumnSpan="2" Margin="20,5" BorderBrush="Bisque" BorderThickness="2"> <ListView.ItemTemplate> <DataTemplate> <TextBlock Text="{Binding}" Padding="5,5" /> </DataTemplate> </ListView.ItemTemplate> </ListView> I can't figure out where this

问题 As I couldn't find any way to peek for data (read data without consuming the buffer) as asked at How to peek StreamSocket for data in UWP apps I'm now trying to make my own "peek" but still no luck. I don't see how I can read data from StreamSocket in the manner which will let me use timeouts and leave the connection usable in case if timeout elapses. In the end, the problem is as follows. In my, let's say, IMAP client, I get response from a server and if this response is negative, I need to

问题 I'm trying to store my 16000hz 16bit mono PCM audio bytes to a wav file in a Windows 10 app. NAudio normaly has a WavFileWriter, but it seems to be gone in the Windows 10 version. I can only seem to find access to new WaveFormat(16000, 16, 1); from https://www.nuget.org/packages/NAudio/1.7.3/ Is there a stream I can use to create the Wav file or its bytes? 回答1: I suspect that NAudio removed WavFileWriter because there's now a substitute in the standard UWP API, in the Windows.Media.Audio

问题 I have troubles with setting AppBarButton visibility in codebehinde.

问题 I want to display a local XML file on a WebView . The XML file references a local XSL file (in the same folder). But the stylesheet is not applied and the reason for this seems to be security concerns. If I open the file in the console of Edge I get XSLT8690: The system cannot locate the object specified. Is there a possibility to allow the XSL transformation of a local file (e.g. like here)? How can I display a local XML file, which references a stylesheet? 回答1: If your XML and XSL file are

问题 first of all I really hope I'm not asking already answered question, I did my research on stack overflow and beyond and so far didn't find answer to my question. I finally accomplished that my Universal windows (10) app makes a project folder for user, inside LocalState folder, but its fine as long as it stays there. Now, I'm trying to generate some simple text file and save in "Project" folder, example path: LocalState\Project1\example.txt. I tried with following code: StorageFolder mapa

I am seeing calls to ActualWidthPropertyChanged, but they are not triggering any call to WidthPropertyChanged. What am I missing? class WindowsElement: DependencyObject {
