问题 Windows UWP app in C#. I have a method that checks a condition and depending on the condition, it may need to show a listview to the user so they can select an item from the list. I have more code in the method, after I potentially show the list view that needs to run after. However, because the listview shows and I have to wait for the SelectionChanged event handler to fire, I cannot figure out how to pause the calling method on that line until the event handler is completed for

问题 I'm deploying my Windows 10 Mobile application on my device. I want to inspect the folder to be sure the application created folders and files. How can I do that? I tried with the webapp in the phone but I access only on the Documents folder.

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 Problem: I have created two APPX-files with version 0.0.1 and version 0.0.2. After the installation of version 0.0.1 the app is visible and accessible. All is ok so far. Now I want to update that app to version 0.0.2. I open the 0.0.2 APPX-file and the installation pop-up comes up. I press the install button and the app seems to install, same like the 0.0.1 installation. After about a minute I open the app again, but against my expectations version 0.0.1 is still installed. I have also tried

问题 I've been trying to get the row index and the column index when specific cell of grid control is tapped. So far nothing... I achieved to take the absolute value of X and Y when I tap somewhere on the grid control. private void gridGameBoard_Tapped(object sender, TappedRoutedEventArgs e) { Grid grd = sender as Grid; Point pos = e.GetPosition(grd); } I've tried this: int row = Grid.GetColumn(grd); int col = Grid.GetRow(grd); Both gives me only zeros no matter where I tap. I didn't find another

问题 How can i make such alist of checkboxes, that they are left aligned to the button, from where it opens, and provide a opening and closing Animation, like in the Alarm & Clock App in Windows 10? I tried with Popups and Flyouts, but there isnt the same effect. 回答1: It looks that this Control in the Alarm & Clock App is actually expanded from a ComboBox control. So we can use a ComboBox to do this, for example: <ComboBox x:Name="comboBox" VerticalAlignment="Center" HorizontalAlignment="Stretch"

问题 I am creating a custom transport controls. In that, I have added an AppBarButton. To change the visibility of that I have created a Property for it, but for some reason, it doesn't work. The AppBarButton is always visible. Code of the Property //To change Visibility for CompactOverlayButton public bool IsCompactOverlayButtonVisible { get { return compactOverlayButton != null && compactOverlayButton.Visibility == Visibility.Visible; } set { if (compactOverlayButton != null) //To neglect the
