问题 In Windows 10 UWP app how do I detect if the current internet connection is Wifi or Cellular? 回答1: In UWP you can check network connectivity using the IsWlanConnectionProfile or IsWwanConnectionProfile properties.

问题 The RenderTargetBitmap class worked with simple Canvas + InkManager (in Windows 8.1) to render ink strokes to an image. UWP introduced InkCanvas and a new Inking API. However, it seems like the RenderTargetBitmap does not work with that. When I try to capture ink strokes with RenderAsync method, no ink strokes get rendered only other objects like Rectangle and so on. Is it a bug or this new API is not meant to be used this way? If not, then how can I render an image out of InkCanvas ? Thanks!

问题 I have a Listview with 20 items in it. I want to scroll the Listview programmatically. ListView?.ScrollIntoView(ListView.Items[0]) will scroll the listview to the first item. ListView?.ScrollIntoView(ListView.Items.Count - 1) will scroll the listview to the bottom of the page. However, I am unable to use the same function to scroll the listview to an item in middle.

问题 I wrote a UWP-App and after generating and installing the .appxbundle, every time I start the App I get a net_http_client_execution_error . The App is starting and running fine, when started in Visual Studio 2015. So there is no chance for me to get the problem, if I debug the app. Update: By default Windows restricts apps to reach the localhost (127.0.0.1). I have running a couch database there. This couch database should run there for our costumers as well. Is it possible to allow a App to
