windows-8.1

问题 In Windows 8, you were able to create your own themes for your application (here's a tutorial). In Windows 8.1 Applications, themes are handled differently: you can change them at run-time and set a theme for a specific control in your XAML (if you don't want to apply the theme to the whole Application). For instance: <Grid x:Name="MainGrid" RequestedTheme="Dark"> However, I could not find a way to create my own themes. The property RequestedTheme takes an enumeration (its type is

问题 I'm trying to find out if a user added new music to the Music folder on the phone since app was last used. I try to do this by checking the DateModified of the Music folder (which updates correctly on the computer when adding new music to the phone): async void GetModifiedDate () { BasicProperties props = await KnownFolders.MusicLibrary.GetBasicPropertiesAsync(); Debug.WriteLine("DATEMODIFIED: " + props.DateModified.ToString()); } Unfortunately this returns: DATEMODIFIED: 1/1/1601 1:00:00 AM

问题 I have a simple piece of XAML that lays out a group of tiles, each with a background image icon. <Grid.Background> <ImageBrush Stretch="None" ImageSource="{Binding ImageSource}" AlignmentY="Center" AlignmentX="Center"/> </Grid.Background> This works fine, except the background image fills the square perfectly.

问题 I'm running into an odd problem. I created a Windows Runtime Component (for Windows Store) that makes some legacy C/C++ code available to .NET via some C# wrapper classes. I wrote a test harness Store App (hereafter referred to as "test1") that references the WRC project (both projects in the same solution). It calls into the component and everything works fine. Next I take the following output files from the WRC project: MyWrtComponent.dll MyWrtComponent.exp MyWrtComponent.pdb MyWrtComponent

问题 Recently I was developing a Universal app for both the Windows Phone and Windows Store. In that app, I was trying to fix the Orientation of the App to Landscape. But in WinRT based apps of Windows Phone 8.1, I failed to find any Orientation option. In the Silverlight apps, we can fix the Orientations as we want. But is there any way to fix the Orientation to Landscape mode in the Universal Apps? It will be very helpful if someone help me in this regard. Thanks in advance. :) 回答1: Under WinRT
