将进度栏从简单副本添加到C驱动器

问题描述

我使用的代码如下：

  My.Computer.FileSystem.CopyFile（
Software\Service Packs \WindowsXP\SP2\WindowsXP-KB835935-SP2-ENU.exe，
C：\Service Pack\WindowsXP-KB835935-SP2-ENU.exe）
 
 Process.Start（C：\Service Pack\WindowsXP-KB835935-SP2-ENU.exe）
  

这只是将Windows XP Service Pack从pendrive复制到上面的C驱动器。

我希望在表单中添加一个进度条，

解决方案

将一个ProgressBar和Timer拖到窗体。

在 Timer1_Tick 下添加以下代码：

代码示例

 私有子Timer1_Tick（）处理Timer1.Tick 
 ProgressBar1.Increment（20）
如果ProgressBar1.Value = ProgressBar1.Maximum然后
 Timer1.Stop 
'当进度条达到最大值时在这里添加要做的事。 
 End If 
 End Sub 
 
 Private Sub Form1_Load（）处理Mybase.Load 
 Timer1.Stop 
 End Sub 
 
 Private Sub Button1_Click（）Handles Button1.Click 
 Timer1.Start 
 End Sub 
  

说明

ProgressBar1.Increment 中指定的值表示增加的百分比。

语句 Timer1.Start 必须添加到事件中您要触发 ProgressBar （不必在 Form_Load 事件下写入）。

希望它能正常工作。

I am using this code:

My.Computer.FileSystem.CopyFile(
            "Software\Service Packs\WindowsXP\SP2\WindowsXP-KB835935-SP2-ENU.exe",
            "C:\Service Pack\WindowsXP-KB835935-SP2-ENU.exe")

        Process.Start("C:\Service Pack\WindowsXP-KB835935-SP2-ENU.exe")

This simply copies Windows XP Service Pack from a pendrive to the C Drive located above.

I wish to add a Progress bar to the Form and need the code in order to do this.

Thank you,

解决方案

Drag a ProgressBar and Timer to the form.

Add the following code under Timer1_Tick event:

Code And Example

Private Sub Timer1_Tick () Handles Timer1.Tick
      ProgressBar1.Increment (20)
      If ProgressBar1.Value = ProgressBar1.Maximum then
           Timer1.Stop
           'Add things here you want to do when progressbar reaches maximum.
      End If
End Sub

Private Sub Form1_Load () Handles Mybase.Load
      Timer1.Stop
End Sub

Private Sub Button1_Click () Handles Button1.Click
      Timer1.Start
End Sub

Explanation

The value specified in the ProgressBar1.Increment means the percentage of increase. It will stop increasing when the value is maximum.

The Statement Timer1.Start must be added to the event from which you want to trigger the ProgressBar (Not necessary to write under the Form_Load event).

Hope it works perfectly.
