问题 I am porting a Silverlight application to UWP. In my Silverlight app, i get the public instance properties: Type t; t.GetProperties(BindingFlags.Instance | BindingFlags.Public); In UWP it look like the GetProperties(BindingFlags.Instance | BindingFlags.Public) method is no longer available.

问题 I have a ListView backed by an ObservableCollection . The user can add a new row, where in code I add a new object to the collection: array.Add(obj) . Now what I'd like to do is give focus to a TextBox in the new row. The problem is that I believe I need to wait until the UI is created, and I don't know of an event that will let me know when the new row is ready. I've tried getting the new container and a reference to TextBox in ListView_SelectionChanged , but I was getting null return values

问题 Summary: I have a collection FrameworkElements (basically web view brushes drawn on rectanlges), and I'd like to save each of these as a PNG file in my UWP app. More details: I followed the example at https://stackoverflow.com/a/17222629/2884981 to split the content of a WebView into separate "pages". I've put the main bits of code at the bottom. At the bottom of GetWebPages() I have return pages; At this point I have a list of all the "pages". What I'd like to do, is then convert each of

问题 My problem is that with UWP-Apps I can not use RSACryptoServiceProvider . That means I have to use CryptographicEngine to en/decrypt data. How can I Import my Public/Private Key to AsymmetricKeyAlgorithmProvider 's ImportKeyPair -Method? How do I have to create the IBuffer parameter? I have two Pem or alternatively xml files, one for Private and one for Public key, which I want to use for en/decryption. They are externally created. I already found a Solution with Chilkat's Rsa Class. But this

问题 I am porting an WP7 Silverlight application to the UWP Windows 10 mobile platform. In my old code I used to check if the keyboard was deployed in the following way: if (DeviceStatus.IsKeyboardDeployed) { // do stuff } else { //do stuff } Now I want to do the same in WM10 but there does not seem to be an equivalent of this function anymore. I already checked the following link And Googled but cannot find it. Does anybody know if you still can detect this in any way? 回答1: I think you can make

问题 I have been to try to use Mysql with c++ in UWP for 2 days...but I could not do so. I already installed Mysql.data and Mysql.ConnectorNet.Data through Nuget.
