问题 I'm building a Windows 8 app and have come up with the following exception: SuspensionManager failed When running the following code: private async void OnSuspending(object sender, SuspendingEventArgs e) { var deferral = e.SuspendingOperation.GetDeferral(); await SuspensionManager.SaveAsync(); deferral.Complete(); } The exception occurs on the third line of the method, and it doesn't really give any detail. I've failed to find anything useful regarding this on the net. Has anyone seen this

问题 My C#/XAML WinRT app makes use of ApplicationData.LocalFolder to store data. I'm wondering if there's any size limit for this folder. I didn't find any information on the web/MSDN... Is this folder limited in size or not? 回答1: As you can read in the documentation available at http://msdn.microsoft.com/en-us/library/windows/apps/hh464917.aspx: There are no general size restriction on local data stored. 来源： https://stackoverflow.com/questions/12857077/size-limit-of-local-folder

问题 I have a ScrollViewer with an Image Control in it. It displays a rather large image. I want my user to be able to zoom into the image using gestures. I therefore enabled the ZoomMode on the Scrollviewer. However the Scrollviewer automatically scrolls back to the left "edge" of the image whenever the user releases its finger, making effectively zooming in and out of the image impossible. This is the Template i am using: <DataTemplate x:Key="SingleItemTemplate"> <ScrollViewer ZoomMode="Enabled"

问题 I've been looking at the XAML Images sample project and the XAML to load an image in that sample looks like this: <Image Source="Assets/image1.jpg"/> However, in my own project I find that I cannot load any images like that. If I try I get E_NETWORK_ERROR when I handle the ImageFailed. Instead, I discovered that I have to use the ms-appx:/// prefix like this: <Image Source="ms-appx:///Assets/image1.jpg"/> Then it works. Any ideas what's different about my project vs the sample that would

问题 I realize that a local SQL Server instance is not accessible to my Windows 8 app. Instead, I have a SQL Server in Azure. In SQL Server Management Studio, I just change the querystring and interact with the Azure database like any other. How can I reference that database in my Windows 8 app? 回答1: You can't access directly on sql databases.. Because Windows 8 Apps different from windows forms. But you can be used web services or azure, amazon services, storage files etc. 回答2: This is what the

问题 Is there a new macro to determine in code if the application is running on WinRT? As I'm working with LoadLibrary , it would be great if there is a macro to replace all calls to LoadLibrary with one to LoadPackagedLibrary ... I'm understanding the documentation correct as in I can load any DLL (as long as it's inside my package) via LoadPackagedLibrary , right?! (And as long as that DLL doesn't use black-listed APIs...) 回答1: I recently updated to Visual Studio 2012, and think I found the

问题 I can't get chrome on windows 8 to open mailto links. They work fine in IE, and they work fine in chrome if the mailto is handled by a website (such as gmail), but I can't get it to work if Outlook is set to handle the uri. Has anyone else faced this issue? 回答1: You should follow the standard bug investigation/reporting path: look up a similar issue at http://crbug.com if none is found, file a new one at http://new.crbug.com That said, http://code.google.com/p/chromium/issues/detail?id=62254

问题 While looking at some official Windows8/"Metro" material, I see this line of xaml: <TextBlock Text="Contoso Cookbook" FontFamily="Segoe UI" FontWeight="SemiLight" FontSize="26.667" /> What?!? A font size of 26.667? I realize this is 2/3rds of 40, and 5/6ths of 32, so maybe there's some conversion thing happening there, but is this going to be the preferred way of setting font sizes, and if so, what are the guidelines for coming up with these seemingly random sizes? 回答1: There are pre-defined
