我刚刚开始使用Windows Store应用程序开发,我只是想要一个非常简单的应用程序:几乎是一个从左到右填充的progres栏,但即使这个任务显然不适合我。DispatcherTimer不会触发
我有以下代码:
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Runtime.InteropServices.WindowsRuntime;
using Windows.Foundation;
using Windows.Foundation.Collections;
using Windows.UI.Xaml;
using Windows.UI.Xaml.Controls;
using Windows.UI.Xaml.Controls.Primitives;
using Windows.UI.Xaml.Data;
using Windows.UI.Xaml.Input;
using Windows.UI.Xaml.Media;
using Windows.UI.Xaml.Navigation;
// The Blank Page item template is documented at http://go.microsoft.com/fwlink/?LinkId=234238
namespace TimeLoader
{
/// <summary>
/// An empty page that can be used on its own or navigated to within a Frame.
/// </summary>
public sealed partial class MainPage : Page
{
private DispatcherTimer refreshTimer;
public MainPage()
{
this.InitializeComponent();
}
void refreshTimer_Tick(object sender, object e)
{
TimePassedBar.Value += 5;
}
private void Page_Loaded(object sender, RoutedEventArgs e)
{
TimePassedBar.Value = 50;
new DispatcherTimer();
this.refreshTimer = new DispatcherTimer();
this.refreshTimer.Interval = new TimeSpan(0, 0, 0, 100);
this.refreshTimer.Tick += refreshTimer_Tick;
this.refreshTimer.Start();
}
}
}
<Page
x:Class="TimeLoader.MainPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:TimeLoader"

<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
<Grid.RowDefinitions>
<RowDefinition/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition></ColumnDefinition>
</Grid.ColumnDefinitions>
<ProgressBar Grid.Row="0" Grid.Column="0" Height="150" Value="75" VerticalAlignment="Center" Name="TimePassedBar"/>
</Grid>
</Page>
现在同样的设置工作得很好,当我这样做是在WPF但是当我开始这个代码生成作为Windows商店应用Tick事件永远不会触发。在构建Windows应用商店应用时,是否需要特别注意特殊情况?我看上去很高,很遗憾在这件事上没有发现任何东西。
谢谢,从我的WPF复制代码时,两个拼写错误,我没有注意到他们中的任何一个xD。非常感谢您帮助我解决这个问题! – 2014-12-11 01:42:30
