问题 It is exciting that Windows 8 is supporting so many languages for Metro App development. One that especially interested me was the HTML5/CSS/JavaScript. What I don't understand, is this code going to get compiled in a sort of executable (like the C#, VB, and C++ option), or would my app basically be running in IE as an actual web page? 回答1: Yes. Javascript is executed on Windows 8 by the Chakra engine. Similar to the .NET just-in-time compiler, it translates javascript to optimized machine

问题 It seems I can't do myObject.BeginAnimation(dp , animation) . Is this a bug or has it been changed? 回答1: You need to use a storyboard. Add your animation to the storyboard and have the storyboard begin the animation. var storyboard = new Storyboard(); var opacityAnimation = new DoubleAnimation { From = 0, To = 1, Duration = DurationHelper.FromTimeSpan(TimeSpan.FromSeconds(1)), }; storyboard.Children.Add(opacityAnimation); Storyboard.SetTargetProperty(opacityAnimation, "Opacity"); Storyboard

问题 I'm migrating/converting/rebuilding a Windows Phone 7.1 app to a Windows 8 Store App. One method I am using in de WP7 app is giving me trouble: private byte[] GetSHA256Key(string data, string secretKey) { byte[] value = Encoding.UTF8.GetBytes(data); byte[] secretKeyBytes = Encoding.UTF8.GetBytes(secretKey); HMACSHA256 hmacsha256 = new HMACSHA256(secretKeyBytes); byte[] resultBytes = hmacsha256.ComputeHash(value); return resultBytes; } Looking at the documentation for Windows Store Apps I came

问题 How do I port a Windows8 app that I built onto a Surface? I've built the app using Visual Studio and I can test it just fine on the desktop machine by just hitting F5. How can I put it onto a Surface to test it without having to publish it to the Store? Thanks. 回答1: This link explains how to test your app on a Surface using remote debugging: http://timheuer.com/blog/archive/2012/10/26/remote-debugging-windows-store-apps-on-surface-arm-devices.aspx A quick summary: 1.

问题 Does anyone know what framework microsoft used to develop the metro like web management portal on windows azure. If so. Is it available to developers? 回答1: I posed the same question and got a lot of hate for it. The winning answer is the Metro UI Pack. It does a lot of what they do in Azure, but you'd have to implement the rest yourself. 回答2: The CSS is probably custom, but the portal uses a few open source libraries for the javascript part: jquery-1.7.1 jquery-ui jsObservable JsRender

问题 Just curious, from a standpoint of WinAPI developer, what desktop do Metro apps run in? This stuff: 回答1: I didn't know that it would be such a secret... so I had to do some investigating and here's what I found: First off, to answer my original question -- the Metro (or Modern UI) stuff runs in the exact same desktop as the "desktop" apps (pardon the pun.) It is actually all very simple. The short answer -- all Microsoft approved Metro stuff runs in the Internet Explorer_Server container

问题 I am learning how to develop Windows 8 Metro style apps but i couldn't found a way to store user data in SQL Server for example. What could i use or how to store user data. 回答1: You cannot access local "desktop services" from the Metro app. So you will not be able to communicate with a local SQL Server. You can use online services that store your information or you can use local storage. Take a look at: How to store and retrieve local application data ApplicationData sample That question is

问题 I'm implementing SQLite database in my Windows Store application (WinRT).

问题 I am working on a Win8-UI-App (previously called Metro...) and trying to implement Periodic (Documentation for different methods) Tile Updates (Live Tiles) for the first time. I found a couple of very good resources on the internet and was able to do it. Unfortunately the question of where I should register for the notifications remained unsolved: Do I have to register for Notifications every time the app starts (e.g. in the App.xaml.cs OnLaunched() Method)? - Or is there an other, more
