UWP API in ASP.NET

由 核能气质少年 提交于 2020-01-30 06:16:08
问题 I'd like to use a piece of Windows 10 specific UWP API (specifically, the Windows.Graphics.Printing3D stuff) in an ASP.NET code-behind DLL. Is there any way to do so? 回答1: While looking for a .NET-only resolution to this one, I've found a moderately clean way - a Win32/64 C++ DLL that would consume UWP API and present a COM- or P/Invoke-based interface to .NET. Create a regular Win32 DLL. Build an interface for .NET to consume - exported functions or objects, depends. In my case, a single

【UWP】使用 LiteDB 存储数据

原文: 【UWP】使用 LiteDB 存储数据 序言： 在 UWP 中，常见的存储数据方式基本上就两种。第一种方案是 UWP 框架提供的 ApplicationData Settings 这一系列的方法，适用于存放比较轻量的数据，例如存个 Boolean 类型的设置项这种是最适合不过的了。另一种方案是用 Sqlite 这种数据库，适合存放数据量大或者结构复杂，又或者需要根据条件查询的场合，例如开发个宝可梦数据查询，或者 Jav 图书馆（咳咳）。 场景分析： 在某些场合，我们很可能是要持久化一个复杂的对象的，例如通过 OAuth 授权成功获取到的用户信息，有可能就类似下面的结构： { "id": 1, "name": "Justin Liu", "gender": 2, "location": { "name": "Melbourne", "name_cn": "墨尔本" } } 又或者做一个 RSS 阅读器，弄个后台服务提前先把数据拉下来，那肯定也要存放起来吧。这相当于要把一个以时间排序为依据的列表进行持久化。 ApplicationData Settings 方案 在以上两种场合，用 ApplicationData Settings 解决起来可能是比较快速的。以第一种情况来说，又可以细分两种存储方案。 A 方案，分字段存放： ApplicationData.Current

How to Javascript notify() with ms-appdata on Windows 10 UWP

由 |▌冷眼眸甩不掉的悲伤 提交于 2020-01-26 03:27:09
问题 Due to file-writing security issues we have tried to switch our app from using ms-appx-web: to using ms-appdata:. But it immediately fails because we rely on window.external.notify() which works fine with ms-appx-web: but seems to behave as a no-op with ms-appdata:. As a test we loaded the following html into a WebView object: <html> <head> <script> function demofunc( str ) { document.getElementById("demo").innerHTML += str; window.external.notify( str ); } </script> </head> <body onLoad=
