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...

问题 I'm using the Windows Phone 8.1 DatePicker It's displaying the date as month/day/year by default and I can't see any way to change this to the 'correct' way of day/month/year .

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 was wondering how I could go about converting an ImageSource object (in my case the source property of an image element) to a WriteableBitmap . The WriteableBitmap(BitmapSource) constructor doesn't work in Windows 8 Metro, so I can't do that. I've tried to load the ImageSource object into a stream and then use WriteableBitmap.SetSource(stream) , but I can't figure out how do load the image in a stream either.

问题 I would like to disable all navigation on my FlipView (scrolling horizontally) from user's input (e.g. mouse wheel and touch screen). The only way the flipview is supposed to change its selected index is programatically, I have already removed the side buttons in the FlipView 's style. I tried changing some of the ScrollViewer 's properties in its style but I can't manage to block everything. Anybody can hint me the correct and clean way to do this? 回答1: I found the solution by overriding the

问题 I have some WP7 code that looks like this: using System.Windows; using System.Windows.Threading; public static class GlobalDispatcher { public static Dispatcher Current { get { return Deployment.Current.Dispatcher; } } } What is the equivalent in WinRT?

问题 I would like to do something like this http://weblogs.asp.net/broux/archive/2011/02/08/silverlight-how-to-watermark-a-writeablebitmapimage-with-a-text.aspx.
