如何在寡妇应用程序中将进度条显示为窗体中心的弹出窗口？ [英] How to show progress bar as popup in center of form in widows application ?

问题描述

嗨
我正在开发windows应用程序，因为我需要弹出进度条，在按钮点击事件中我需要在Windows窗体应用程序的中心显示进度条，例如。当开始关闭进度条时代码之间执行2到5分钟，所以我需要向用户显示一条消息（如Please Wait ...）。在按钮形式已经得到控制，所以我不能在设计时将进度条放在窗体的中心。

 私人  Sub  BtnCheckin_Click（ ByVal  sender  As  System。 Object ， ByVal  e  As  System.EventArgs）< span class =code-keyword>句柄 BtnCheckin.Click 
 ' 这里需要启动显示进度条 
 
 .................. ....... 
 ........................ 
 ........... ........... 
 ........................ 
 ....... .................. 
 ........................ 
 ...................... 
 ........................ 
 
 ' 这里需要关闭进度条 
 
 结束  Sub  

注意：为什么代码执行2到5分钟，bcz我将绑定（超过10000）节点到树视图，因此在树视图中绑定节点需要2到5分钟。

如果你不能要查看解决方案，请参阅：

  //   --BEGIN  
  //  在我的主要部分主要表单 
 pb.Style = ProgressBarStyle.Marquee; 
 pb.MarqueeAnimationSpeed =  30 ; 
 
  private  BackgroundWorker worker =  null ; 
 worker =  new  BackgroundWorker（）; 
 worker.DoWork + =  new  DoWorkEventHandler（worker_DoWork）; 
 worker.RunWorkerAsync（）; 
  //   --- END  
 
  void  worker_DoWork（ object  sender，DoWorkEventArgs e）
 {
 BuildTree（）; 
} 

概念是使用BackgroudWorker。

如果您想在父表单的中心显示带有progressbarr的表单，请使用正确的 StartPosition [ ^ ]或位置。

Private Sub BtnCheckin_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnCheckin.Click
'Here need to start to show progress bar

.........................
........................

End Sub

Note: why code ececute 2 to 5 mins,bcz i will bind(more than 10000) node to treeview,so it take 2 to 5 mins to bind node in treeview.

Pls reply asap

Please, read my comment first.
Have a look here: http://www.experts-exchange.com/Programming/Languages/.NET/Q_23786595.html[^]

In case you're not able to view the solution, please see:

//--BEGIN
//  In my main section of the 'main form'
            pb.Style = ProgressBarStyle.Marquee;
            pb.MarqueeAnimationSpeed = 30;

        private BackgroundWorker worker = null;
        worker = new BackgroundWorker();
        worker.DoWork +=new DoWorkEventHandler(worker_DoWork);
        worker.RunWorkerAsync();
//---END

        void worker_DoWork(object sender, DoWorkEventArgs e)
        {
            BuildTree();
        }

The concept is to use BackgroudWorker.

If you would like to show form with progressbarr on the center of parent form, use proper StartPosition[^] or Location.
