问题 Is there a control to show an animated gif in a Windows Store (Metro) app in Windows 8? I am using C# and XAML with databinding. 回答1: The Image control doesn't support animated GIFs.

However, you can display an animated gift

问题 On button click I want to open the default metro browser (usually IE) without opening a new tab/page, just open the browser, If it is already running then just switch to it as it is to it's current state. Is there a way to do that? 回答1: This is just something to try, and may or may not work in your scenario: If you know the url that is open in the browser, your Windows Store app could launch that same url with the launcher. In my app, when I launch the same url multiple times, IE will pop up

问题 I have a BitmapImage object, which already has its source etc set. I simply want to save it to my apps local storage folder, so that I can reference it at other points in the program. I just cannot figure out how to get it from object to file though! I've found solutions to similar problems for WP7, but its just not the same. Ive got as far as creating my image from a Base64 string (which works as I can load the image into a UI image viewer and see it) and have called it img , and I know I

问题 I really like C# and I am familiar with it, but I also want to use HTML5/JavaScript to manage the UI for my Windows 8 Metro app. So, how can I import and use objects from a library made in C# in the Javascript files? Example here is the starting JS code for an empty HTML5/JS project... // For an introduction to the Blank template, see the following documentation: // http://go.microsoft.com/fwlink/?LinkId=232509 (function () { "use strict"; var app = WinJS.Application; app.onactivated =

问题 I am tempting to look at the ToDoMVC samples and have tried porting them to a Win8 JS app by just copying and pasting the code but also having the relevant WinJS libs referenced. Due to MS security principals around InnerHTML etc I have referenced jQuery-Win8 which attempts to get around the issue however in the Angular and Backbone examples when I run the app I get an exception on appendChild I've read in some places you should be able to continue running the app but if I do press Continue
