问题 I am running into a problem with my background task on Windows Mobile 10 (build 10.0.14393.82). In my background task, HTTP client is sometimes throwing an Exception with the error (note it seems to happen when the phone is locked): The server name or address could not be resolved The phone shouldn't have an issue resolving the address, since it resolves it fine when running in the foreground. Has anyone else seen this issue, or have any ideas? 回答1: check the IsNetworkRequested property when

问题 The issue I've got an application that tracks vehicles on a map. However I cannot get the little buggers to rotate in the direction of their motion. Basically, all of them are going sideways! Ugh!

问题 I want to bind to a text block the current size of the window. In the current implementation the size of the main window is set at run time BUT if I resize the window after the application has launched the new size is not updated in the text block. <Grid x:Name="grid" Background="#FFE8E8E8"> <TextBox x:Name="textBoxSample" Width="300" Height="200" Text="{Binding ActualWidth, ElementName=grid}"></TextBox> </Grid> 回答1: In UWP, the Grid controls normally automatically resize to fit its parent

问题 I am trying to scan a USB drive that is inserted into a Raspberry Pi running Windows 10 IoT Core for a specific file in a specific folder. I am currently able to detect when a USB drive is added or removed from the device using Windows.Devices.Enumeration.DeviceWatcher and can find the DeviceId using that as well. I did this using the DeviceEnumerationAndPairing demo project. I am aware that StorageDevice.FromId() would work for this usually but it seems to not agree with Windows 10 IoT Core.

问题 On Package.Appmanifest we can define SplashScreen background color that is used for: 1) SplashScreen background - pretty obvious 2) to fit the space between new window border and not (yet) resized content when user is resizing the app window If you don't know what I am writing about under 2) - just run Xbox app (or any other written with UWP), grab window border and then quickly move the window border back and forward. The problem is that I would like to have two separate colors for that.

问题 I have two different Unity projects, one is a HoloLens application and the other is the desktop application. My goal is to manipulate an object in the HoloLens application through the desktop application. At the moment I have Unet working when the HoloLens is the host and the desktop acting as the client. Manipulating through the HoloLens and transferring that to the desktop application works, but it doesn't vice versa. I am unable to connect to the desktop application when it serves as the

问题 I'm experiencing the Registration of the app failed. (0x80073cf6) error. What I've tried so far: Delete the package in AppData (I can't find it anymore there, the package family name has been changed to my associated store listing). Repair Visual Studio Acquire developer license Make a new project (that works, for the 1st time, after that same error). It happens on my phone (950XL, developer unlocked) and on my machine.

问题 In my UWP app, I'm trying to refresh the density bars on a calendarview if the user clicks a button, the problem is that, although calendarView.UpdateLayout(); should re-run the CalendarViewDayItemChanging event, it runs only when the CalendarView is loaded the first time.
