问题 I'm working on creating custom controls for a XAML app for Windows 8.1 Universal/UWP and keep finding little nuances. I can't seem to find any great tutorials on creating custom implementations of existing controls (like the TextBox) so I've been looking through the source code of controls like Telerik to try and understand how their custom controls are working.

问题 I've got a Windows 10 UWP application written in C#. I'm using SQLite to store my data locally. The issue I'm experiencing is that the file is never saved and/or retrieved using this code. It should work, but I can't find out what's wrong. dbExists always evaluates to false, so what am I missing here? private SQLiteConnection localConn; private string dbPath = Path.Combine(Windows.Storage.ApplicationData.Current.LocalFolder.Path, "myDatabase.db"); public async void DBInit() { bool dbExists =

This is the code I developed, using examples in Win Dev Center and some other answers here on Stack Overflow: public sealed partial class MainPage : Page { // Some other things private void

问题 This official MSDN document describes how to share data between Universal Windows Platform (UWP) apps. But can we pass a string to an UWP app from a Windows Forms app and launch the UWP app from Windows Forms app? I did not find any document for this scenario. I'm using C# but the language does not matter in this scenario. NOTE : In our case, it's a long string that contains data that Windows Forms app wants to pass to the UWP app that uses that data. 回答1: The easiest way to do this would be
