问题 I am currently working on a Windows 8 app which needs to store some tables. Currently, I am using XML files with XDocument classes to solve the purpose. It employs save and load methods using GetFileAsync and CreateFileAsync etc. Moreover, there save and load methods are called by different events. However, whenever there are repeated calls, an exception is thrown telling me that file access is denied. Expected behavior - more details here! While there are dirty methods to avoid this (like

问题 I need to display an animated GIF in my metro app, but I can't find any control that allows it. (I tried Image , MediaElement and MediaPlayer from the Player Framework) Is it possible somehow to display an animated GIF? 回答1: While I haven't checked if it works and it might not work for you due to airspace issues - you could try hosting your gif in a WebView control. It might be a lot easier than the otherwise better solutions proposed by Norbert and Carl. 回答2: You can achieve this natively by

问题 I'm trying to create an LINQ Query with 4 arguments in the Where clause. It's a Windows 8 App project and I'm using an SQLite Database. (SQLite implementation ) Here's the code snippet: public List<FinancialListBoxExpenseItem> retrieveExpenseItems(int month, int year, bool isPaid, StaticResources.FrequencyEnum frequencyEnum) { List<FinancialListBoxExpenseItem> tmpList = null; connection.RunInTransaction(() => { var items = from s in connection.Table<FinancialListBoxExpenseItem>() where (s

问题 Below is a sample implementation that uses metro API and data binding (using MVVM) to populate list of folders in a drop down list. The View model‘s constructor uses SetFolders method (private async), which calls an awaitable method fileService.GetFoldersAsync() to get list of folders. The folders list is then gets assigned to the property called “FoldersList”. XAML uses this property to populate a drop down list using the data binding. I wonder is there a better way to set the FoldersList

问题 My WPF application needs to list the localized names of all Metro/WinRT applications installed for the user. I created a repo to store a working sample for the code presented: https://github.com/luisrigoni/metro-apps-list 1) Using PackageManager.FindPackagesForUser() method var userSecurityId = WindowsIdentity.GetCurrent().User.Value; var packages = packageManager.FindPackagesForUser(userSecurityId); foreach (var package in packages) Debug.WriteLine(package.Id.Name); } // output: // Microsoft

问题 i can't seem to find a dependency injection framework for windows 8 metro apps. Is there a framework for win8 metro apps? Ninject is not yet support for win8 metro. So does anybody have a suggestion? (Castle, Spring, ...) 回答1: Here is the source for Ninject WinRT: https://github.com/remogloor/ninject It just not yet released. 回答2: You could try Unity 3.0 for .NET4.5 Preview. 回答3: I've been using the Beta version of Autofac Portable Library (which is supported in Metro apps) and it is working

问题 I'm currently working on a metro game for Windows 8 using C# and SharpDX. The project is going well, but recently there's been a need to start tracking down memory leaks and I'm not really sure where to begin. The built in memory profiler in Visual Studio 11 doesn't work for metro apps yet, WinDBG can't seem to connect to metro apps (unless I'm using it incorrectly), and I'm having a hard time finding any information about looking at managed allocations in .NET 4.5 for metro. Does anyone have

问题 When my app is running in Windows 8 WINRT can I prevent the OS to go to locked screen/sleep mode? 回答1: You can use the DisplayRequest class to indicate that you are busy playing back something that requires the display to stay active and un-dimmed. A good how-to article with sample code is available here. Don't use it frivolously, it is quite detrimental to power consumption. Good odds that the Store will reject your app if you use it for no obvious benefit to the user. 回答2: You cannot
