I'm currently looking to implement a CommandBar for a WinRT Windows Phone 8.1 app. Overall it is very straightforward but I am unable to style the control. I have themed my app so that the accent colour has been changed to green. This works well for pretty much everywhere in the app (buttons, textblocks etc.) but not for the AppBarButton. The brushes I'm overriding are SystemColorControlAccentBrush and PhoneAccentBrush but changing these does not make any difference to the colour of the AppBarButton when pressed: Any idea what I'm doing wrong/can this colour be changed? Set the CommandBar's

I'm beginner in Metro Style Developing, I tried to make a small game that's need a timer, countdown from 10 to 0. But at this Visual Studio there is no Timer Component, and DispatcherTimer Not mapped to an xmlns. I Tried to use TimeSpan, that have this field "TicksPerSecond" But this example dosen't help me to make my countdown timer : http://msdn.microsoft.com/en-us/library/system.timespan.tickspersecond.aspx TimeSpan also have this method "FromSeconds", and i Can't also use this one for my countdown timer : http://msdn.microsoft.com/en-us/library/system.timespan.fromseconds.aspx also I Read

I have a Windows RT app where I programmatically change the Bitmap in the Image component. All works well with the XAML and the code below except the flickering we see when the image is changed. What should I change to get rid of the flickering? XAML : <Page x:Class="iSurfBrainViewProto01.MainPage" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="using:iSurfBrainViewProto01" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc

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 FrameworkElement.RequestedTheme ) and an enumeration by definition cannot be extended (in C#). Also, if I want

The Metro documentation states that the applications are self-consistent (no shared DLL’s, etc), So I’m just wondering how you can create a modular, BIG Metro application by creating reusable components/libraries. Considering the case for HTML5/JavaScript Metro apps, if a lot of them should contain the same CSS and JavaScript (consider jQuery, templates) or WinJS scripts then it doesn't look quite good … I expected some form of libraries/reuse to exist from the start. The HDD space is definitely cheap nowadays but I think that a versioned library repository should be in place and the

When I create a winrt component using WRL, the problem is that I can only use ABI::Windows::xxx namespace, and I cannot use Windows::UI::Xaml::Media::Imaging namespace in WRL. Then, how to create a build-in winrt component as a return value? // idl import "inspectable.idl"; import "Windows.Foundation.idl"; import "Windows.UI.Xaml.Media.Imaging.idl"; namespace Decoder { interface IPhotoDecoder; runtimeclass PhotoDecoder; interface IPhotoDecoder : IInspectable { HRESULT Decode([in] int width, [in] int height, [out, retval] Windows.UI.Xaml.Media.Imaging.BitmapImage **ppBitmapImage); } [version

I am trying to start video preview capture from the camera in my UWP app but StartPreviewAsync throws an exception Sample Code: MediaCapture mc = new MediaCapture(); await mc.InitializeAsync(); await mc.StartPreviewAsync(); This error occurs because currently StartPreviewAsync requires a sink to output frames to. This can be fixed by creating a capture element in xaml to display the frames. <CaptureElement Name="captureElement"/> now code can be updated to display the preview to the screen MediaCapture mc = new MediaCapture(); await mc.InitializeAsync(); captureElement.Source = mc; await mc
