遍历驱动器
Private Sub ShowDrives()
Dim d() As String
d = System.IO.Directory.GetLogicalDrives()
Dim en As System.Collections.IEnumerator

en = d.GetEnumerator
While en.MoveNext
Console.WriteLine(CStr(en.Current))
End While
End Sub



编写随Windows启动运行的程序
通过设置和读取注册表，可以实现我们的应用程序随Windows的启动即可执行的功能。下面就是实现的代码：

Form1.vb

Imports Microsoft.Win32.Registry
Public Class Form1
Inherits System.Windows.Forms.Form

#Region \" Windows 窗体设计器生成的代码 \"
Public Sub New()
MyBase.New()
\'该调用是 Windows 窗体设计器所必需的。
InitializeComponent()
\'在 InitializeComponent() 调用之后添加任何初始化
End Sub

\'窗体重写处置以清理组件列表。
Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)
If disposing Then
If Not (components Is Nothing) Then
components.Dispose()
End If
End If
MyBase.Dispose(disposing)
End Sub

\'Windows 窗体设计器所必需的
Private components As System.ComponentModel.IContainer

\'注意：以下过程是 Windows 窗体设计器所必需的
\'可以使用 Windows 窗体设计器修改此过程。
\'不要使用代码编辑器修改它。
Friend WithEvents CheckBox1 As System.Windows.Forms.CheckBox
