在任务栏中显示进度条我做错了什么？

发布于 2024-12-28 08:03:27 字数 637 浏览 4 评论 0原文

在我上一篇文章之后，我试图完成这项工作

，我有以下代码（已编辑）：

 public partial class Form1 : Form
 {
   ...
   private TaskDialog Taskbar = new TaskDialog();
 }

 private void timer1_Tick(object sender, EventArgs e)
    {
        Taskbar.ProgressBar.Value = progressBar1.Value;
    }

 private void button2_Click(object sender, EventArgs e)
    {
      bgWorker.RunWorkerAsync();
    }

 bgWorker_dowork()
 {
   timer1.Enabled = true;
      timer1.Start();

      while(progressBar1.Value < progressBar1.Maximum)
      {
        progressBar1.Value++;
      } 
  }

我做错了什么？

编辑：我无法让它在任务栏上最小化时显示进度条，尽管我做了建议的更改。

Following my previous post iam trying to make this work

I have the following code (Edited):

 public partial class Form1 : Form
 {
   ...
   private TaskDialog Taskbar = new TaskDialog();
 }

 private void timer1_Tick(object sender, EventArgs e)
    {
        Taskbar.ProgressBar.Value = progressBar1.Value;
    }

 private void button2_Click(object sender, EventArgs e)
    {
      bgWorker.RunWorkerAsync();
    }

 bgWorker_dowork()
 {
   timer1.Enabled = true;
      timer1.Start();

      while(progressBar1.Value < progressBar1.Maximum)
      {
        progressBar1.Value++;
      } 
  }

那是因为您阻塞了 GUI 线程，

  while(true)
  {
    progressBar1.Value++;
  }

这将导致它锁定并阻止它更新 UI。

永远不要在主线程上运行这样的循环，使用 BackGroundWorker 来处理类似的事情。

That's because you're blocking your GUI thread

  while(true)
  {
    progressBar1.Value++;
  }

This will cause it to lock and prevent it from updating the UI.

Never run such loops on your main thread, use a BackGroundWorker for stuff like that.

确保进度条的值不应超过最大值。

ProgressBar.Maximum 属性

ProgressBar.Minimum属性

 while (progressBar1.Value < progressBar1.Maximum) 
 { 
       progressBar1.Value++; 
       Application.DoEvents();//This will update the UI paintings 
                              //which is not happening prior to this code.     
 }

Make sure the value of the Progress Bar should not exceed the Maximum Value.

ProgressBar.Maximum Property

ProgressBar.Minimum Property

 while (progressBar1.Value < progressBar1.Maximum) 
 { 
       progressBar1.Value++; 
       Application.DoEvents();//This will update the UI paintings 
                              //which is not happening prior to this code.     
 }
