Windows应用程序-灾难性故障( HRESULT: 0x8000FFFF (E_UNEXPECTED)例外)
Windows应用程序-灾难性故障( HRESULT: 0x8000FFFF (E_UNEXPECTED)例外)
提问于 2013-11-18 22:14:08
我试图在C#中编写一个小型库，以便将一些类和UI元素重用到不同的项目中。
我想放在这个库中的一个UI元素是一个非常简单的UserControl：
<UserControl
x:Class="MyProjet.UiUtil.Progress"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:MyProjet.UiUtil"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d"
d:DesignHeight="300"
d:DesignWidth="400">
<UserControl.Resources>
<Style x:Key="BasicTextStyle" TargetType="TextBlock">
<Setter Property="Foreground" Value="{StaticResource ApplicationForegroundThemeBrush}"/>
<Setter Property="FontSize" Value="{StaticResource ControlContentThemeFontSize}"/>
<Setter Property="FontFamily" Value="{StaticResource ContentControlThemeFontFamily}"/>
<Setter Property="TextTrimming" Value="WordEllipsis"/>
<Setter Property="TextWrapping" Value="Wrap"/>
<Setter Property="Typography.StylisticSet20" Value="True"/>
<Setter Property="Typography.DiscretionaryLigatures" Value="True"/>
<Setter Property="Typography.CaseSensitiveForms" Value="True"/>
</Style>
<Style x:Key="BaselineTextStyle" TargetType="TextBlock" BasedOn="{StaticResource BasicTextStyle}">
<Setter Property="LineHeight" Value="20"/>
<Setter Property="LineStackingStrategy" Value="BlockLineHeight"/>
<!-- Aligne correctement le texte sur sa ligne de base -->
<Setter Property="RenderTransform">
<Setter.Value>
<TranslateTransform X="-1" Y="4"/>
</Setter.Value>
</Setter>
</Style>
<Style x:Key="HeaderTextStyle" TargetType="TextBlock" BasedOn="{StaticResource BaselineTextStyle}">
<Setter Property="FontSize" Value="56"/>
<Setter Property="FontWeight" Value="Light"/>
<Setter Property="LineHeight" Value="40"/>
<Setter Property="RenderTransform">
<Setter.Value>
<TranslateTransform X="-2" Y="8"/>
</Setter.Value>
</Setter>
</Style>
<Style x:Key="SubheaderTextStyle" TargetType="TextBlock" BasedOn="{StaticResource BaselineTextStyle}">
<Setter Property="FontSize" Value="26.667"/>
<Setter Property="FontWeight" Value="Light"/>
<Setter Property="LineHeight" Value="30"/>
<Setter Property="RenderTransform">
<Setter.Value>
<TranslateTransform X="-1" Y="6"/>
</Setter.Value>
</Setter>
</Style>
</UserControl.Resources>
<Grid x:Name="GridRoot" Width="{Binding Path=GridWidth}" Height="{Binding Path=GridHeight}" Background="{StaticResource ApplicationPageBackgroundThemeBrush}">
<Grid.RowDefinitions>
<RowDefinition Height="140" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<TextBlock x:Name="TxtTitle" Grid.Row="0" Text="{Binding Path=Title}" Style="{StaticResource HeaderTextStyle}" TextAlignment="Center" TextWrapping="Wrap" Margin="12,12,12,0" VerticalAlignment="Center" HorizontalAlignment="Center" />
<StackPanel Grid.Row="1" VerticalAlignment="Center" HorizontalAlignment="Center">
<TextBlock x:Name="TxtDescription" Text="{Binding Path=Description}" TextAlignment="Center" Style="{StaticResource SubheaderTextStyle}" TextWrapping="Wrap" />
<ProgressBar IsIndeterminate="True" Margin="0, 15" Width="350" />
</StackPanel>
</Grid>
</UserControl>而背后的密码是：
using Windows.UI.Xaml;
using Windows.UI.Xaml.Media;
namespace MyProjet.UiUtil
{
public sealed partial class Progress
{
/// <summary>
/// Inner class for MVVM.
/// </summary>
public sealed class ViewModelProgress
{
public string Title { get; set; }
public string Description { get; set; }
public double GridHeight
{
get
{
return Window.Current.Bounds.Height;
}
}
public double GridWidth
{
get
{
return Window.Current.Bounds.Width;
}
}
}
/// <summary>
/// Default constructor.
/// </summary>
/// <param name="title"></param>
/// <param name="description"></param>
/// <param name="backgroundColor"></param>
/// <param name="titleForeground"></param>
/// <param name="descriptionForeground"></param>
public Progress(string title, string description, Brush backgroundColor, Brush titleForeground, Brush descriptionForeground)
{
InitializeComponent();
GridRoot.Background = backgroundColor;
TxtTitle.Foreground = titleForeground;
TxtDescription.Foreground = descriptionForeground;
this.DataContext = new ViewModelMBProgressHUD() { Title = title, Description = description };
}
}
}这里有一个示例，说明如何在Windows应用程序的MainPage中使用此用户控件：
using System;
using Windows.UI;
using Windows.UI.Xaml;
using Windows.UI.Xaml.Controls.Primitives;
using Windows.UI.Xaml.Media;
using Windows.UI.Xaml.Navigation;
namespace SampleProject
{
public sealed partial class MainPage
{
private Popup _popup;
private DispatcherTimer _timer;
public MainPage()
{
this.InitializeComponent();
}
protected override void OnNavigatedTo(NavigationEventArgs e)
{
base.OnNavigatedTo(e);
_popup = new Popup() { Child = new Progress("Mon Titre", "Ma description", new SolidColorBrush(Colors.Magenta), new SolidColorBrush(Colors.Green), new SolidColorBrush(Colors.Orange)), IsOpen = false };
_timer = new DispatcherTimer() { Interval = TimeSpan.FromSeconds(5) };
_timer.Tick += timer_Tick;
}
private void timer_Tick(object sender, object e)
{
_timer.Stop();
_popup.IsOpen = false;
BtnDisplay.IsEnabled = true;
}
private void BtnDisplay_Click(object sender, RoutedEventArgs e)
{
BtnDisplay.IsEnabled = false;
_timer.Start();
_popup.IsOpen = true;
}
}
}当我将UserControl文件复制到示例项目中时，一切正常工作，但是当我从库中使用UserControl (包为nuget依赖项)时，我有以下错误消息和代码：
灾难性故障( HRESULT: 0x8000FFFF (E_UNEXPECTED)除外) Windows.UI.Xaml.Controls.Frame.NavigationFailed未被处理。
我在互联网上读到，评论或取消评论这句话会有帮助：
base.OnNavigatedTo(e);对我来说，这不会改变任何事情..。
希望有人能帮我！
提前通知你！

我所犯的错误似乎与这个主题有关：http://support.microsoft.com/kb/2739194/en-us

当我得到这个错误(没有其他内部异常)时-它被链接到一个DsiplayMemberPath属性在一个ListView。删除它会使它再次工作。
这个人似乎也有类似的问题，但没有明确原因导致错误。
作为一种解决办法，我重写了模型对象上的ToString方法，以显示我想要的属性。
