问题 I'm Trying to make app send a pulse to a relay. I got it done with a Button_click, but now I want to do it with any keystroke. What Can I use for this? I read about KeyDown but I don't really know how to integrate it, Any help would be much appreciated. Thank you in advance! Here is how my code looks like: private void Button_Click(object sender, RoutedEventArgs e) { if (relay_state == 0) { relayPin.Write(GpioPinValue.Low); relay_state = 1; } else if (relay_state == 1) { relayPin.Write

问题 Defined Light theme ( <AcrylicBrush TintColor="Red"/> ), Dark, ( <AcrylicBrush TintColor="Orange"/> ) in App.xaml. Per this post, Changing UWP project's Target Version from 1803 to 1809 disables NavigationView's Acrylic texture - why?, I added the following to ShellPage.xaml. The expected behavior when I toggle between Light and Dark theme is that the app NavigationView control will have an AcrylicBrush tint that toggles between Red and Orange.

问题 I've developed an UWP app for a client: as we encountered some bugs that I can't reproduce on my device, we've implemented HockeyApp . The client wanted to gain time/money so I only used the basis crash report: HockeyClient.Current.Configure("xxxxxx", new TelemetryConfiguration() { EnableDiagnostics = true }) .SetExceptionDescriptionLoader((Exception ex) => { return "Exception HResult: " + ex.HResult.ToString(); }); But it seems that isn't enough, as the doesn't allow me to fix the latest

问题 I'm trying to develop an UWP app that is able to continually track the user's location in an in-process background task. I've been looking at the Microsoft sample code on GitHub (geolocation / Secenario3_BackgroundTask) but the problem there is that it is based on a TimeTrigger. The shortest interval that TimeTrigger allows is 15 minutes, but I need to get location updates much more frequently. Let's say at least once per minute. Is that possible at all? I've seen that there is a

问题 Having spent some time reading up on the Windows.Storage classes and methods, I'm a bit shocked to find that there is no simple way to retrieve a list of the internal drives on a machine using UWP. I've found examples such as this: How to get logical drives names in Windows 10?, but this provides the removable drives only (Flash drives, DVD drive, etc). I know I can allow the user to select a folder and that'll provide me with the handle to the selected drive, but it seems clunky as I want

问题 I have a problem with a Windows 10 UWP Store App. In the app are two pages (Page1 and Page2) with similar xaml controls, but one page (Page1) cause a lot of problems while testing the app by microsoft. If they try to start the app the initialization of Page1 throw an exception. When I remove one specific xaml control all is fine, but Page2 contains exactly the same controls and works perfectly. On my local machine I have no exceptions, no warnings, the windows certification kit say the app
