进度条直到加载内容 [英] Progress bar until content is loaded

问题描述

大家好，

我正在使用Vb.Net开发Windows Phone 8.0应用程序。

我创建了一个加载页面作为控件我称之为弹出宽度函数ShowSplash（）

这是我的代码：

 

Private Sub ShowSplash（）



        popup.Child =新的LoadingPage

        popup.IsOpen = True



        Dim bw As New BackgroundWorker



        AddHandler bw.DoWork，AddressOf backroungWorker_DoWork

        AddHandler bw.RunWorkerCompleted，AddressOf backroungWorker_RunWorkerCompleted

        bw.RunWorkerAsync（）



   结束分


    Private Sub backroungWorker_DoWork（发件人为对象，e为DoWorkEventArgs）

        Thread.Sleep（9000）

   结束分


    Private Sub backroungWorker_RunWorkerCompleted（sender As Object，e As RunWorkerCompletedEventArgs）

        Me.Dispatcher.BeginInvoke（功能（）

                &NBSP ;   popup.IsOpen =假

                  结束功能）

   结束Sub

问题是：现在我使用了9秒的thread.Sleep但是我想显示加载页面，直到加载页面内容（加载时间可以每页都不同）。我该怎么办 ？！

感谢所有

您好卢卡，可能是
我的文章对你有帮助......

也许你可以使用Tasks而不是BackgroundWorker。

问候。

Hi all,

I'm developing a Windows Phone 8.0 App with Vb.Net.

I've created a loading page as control which I call as popup width the functions ShowSplash()

Here's my code:

 

Private Sub ShowSplash()

        popup.Child = New LoadingPage
        popup.IsOpen = True

        Dim bw As New BackgroundWorker

        AddHandler bw.DoWork, AddressOf backroungWorker_DoWork
        AddHandler bw.RunWorkerCompleted, AddressOf backroungWorker_RunWorkerCompleted
        bw.RunWorkerAsync()

    End Sub

    Private Sub backroungWorker_DoWork(sender As Object, e As DoWorkEventArgs)
        Thread.Sleep(9000)
    End Sub

    Private Sub backroungWorker_RunWorkerCompleted(sender As Object, e As RunWorkerCompletedEventArgs)
        Me.Dispatcher.BeginInvoke(Function()
                                      popup.IsOpen = False
                                  End Function)
    End Sub

Question is: now I use thread.Sleep of 9 seconds but I want to show the loading page until page content is loaded (the loading time can be different for each page). What can I do? 

Thanks all!

Hi Luca, May be my article helps to you...

May be you can use Tasks instead of BackgroundWorker, too.
