得到顯示器解析度
Dim X As Short = System.Windows.Forms.Screen.PrimaryScreen.Bounds.Width
Dim Y As Short = System.Windows.Forms.Screen.PrimaryScreen.Bounds.Height
MsgBox("您的顯示器解析度是:" & X & " X " & Y)

得到特殊檔案夾的路徑
'"Desktop"案頭檔案夾路徑
MsgBox(Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory))
'"Favorites"收藏夾路徑
MsgBox(Environment.GetFolderPath(Environment.SpecialFolder.Favorites))
'"Application Data"路徑
MsgBox(Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData))

'通用寫法
'Dim SPEC As String = Environment.GetFolderPath(Environment.SpecialFolder.XXXXXXX)
'XXXXXXX是特殊檔案夾的名字

得到作業系統版本資訊
MsgBox(Environment.OSVersion.ToString)

得到當前登入的使用者名稱
MsgBox(Environment.UserName)

得到當前應用程式的路徑
MsgBox(Environment.CurrentDirectory)

開啟和關閉CD-ROM
'先建立模組
Module mciAPIModule
  Declare Function mciSendString Lib "winmm.dll" Alias "mciSendStringA" _
  (ByVal lpstrCommand As String, ByVal lpstrReturnString As String, _
  ByVal uReturnLength As Integer, ByVal hwndCallback As Integer) As Integer
End Module

'開啟CD-ROM
Dim lRet As Long
lRet = mciSendString("set cdAudio door open", 0&, 0, 0)

'關閉CD-ROM
Dim lRet As Long
lRet = mciSendString("set cdAudio door Closed", 0&, 0, 0)

得到電腦IP和電腦全名
Dim MYIP As System.Net.IPHostEntry = System.Net.Dns.GetHostByName(System.Net.Dns.GetHostName)
MsgBox("您的IP地址:" & (MYIP.AddressList.GetValue(0).ToString))
MsgBox("您的電腦全名:" & (MYIP.HostName.ToString))

使用win32_operatingSystem (wmi Class)得到電腦資訊
'添加ListBox在Form1_Load事件裡,並引用system.Managment
Dim opSearch As New ManagementObjectSearcher("SELECT * FROM Win32_OperatingSystem")
Dim opInfo As ManagementObject
For Each opInfo In opSearch.Get()
  ListBox1.Items.Add("Name: " & opInfo("name").ToString())
  ListBox1.Items.Add("Version: " & opInfo("version").ToString())
  ListBox1.Items.Add("Manufacturer: " & opInfo("manufacturer").ToString())
  ListBox1.Items.Add("Computer name: " & opInfo("csname").ToString())
  ListBox1.Items.Add("Windows Directory: " & opInfo("windowsdirectory").ToString())
Next

列出電腦安裝的全部字型,並添加到ListBox
'建立Form並添加ListBox和Button
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim fntCollection As InstalledFontCollection = New InstalledFontCollection()
Dim fntFamily() As FontFamily
fntFamily = fntCollection.Families
ListBox1.Items.Clear()
Dim i As Integer = 0
For i = 0 To fntFamily.Length - 1
  ListBox1.Items.Add(fntFamily(i).Name)
Next
End Sub

使用Win32_Processor列出處理器的資訊
Imports System.Management
Public Class Form1
  Inherits System.Windows.Forms.Form

#Region " Windows 表單設計器產生的程式碼 "

  Public Sub New()
    MyBase.New()

    '該調用是 Windows 表單設計器所必需的。
