一、得到显示器分辨率
Dim X As Short = System.Windows.Forms.Screen.PrimaryScreen.Bounds.Width Dim Y As Short = System.Windows.Forms.Screen.PrimaryScreen.Bounds.Height MsgBox("您的显示器分辨率是:" & X & " X " & Y)
二、得到特殊文件夹的路径
'"Desktop"桌面文件夹路径 MsgBox(Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory)) '"Favorites"收藏夹路径 MsgBox(Environment.GetFolderPath(Environment.SpecialFolder.Favorites)) '"Application Data"路径 MsgBox(Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData))
'通用写法 'Dim SPEC As String = Environment.GetFolderPath(Environment.SpecialFolder.XXXXXXX) 'XXXXXXX是特殊文件夹的名字
三、得到操作系统版本信息
MsgBox(Environment.OSVersion.ToString) 得到当前登录的用户名 MsgBox(Environment.UserName) 得到当前应用程序的路径 MsgBox(Environment.CurrentDirectory)
四、打开和关闭CD-ROM
'先新建模块 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 '打开CD-ROM Dim lRet As Long lRet = mciSendString("set cdAudio door open", 0&, 0, 0) 关闭CD-ROM Dim lRet As Long lRet = mciSendString("set cdAudio door Closed", 0&, 0, 0)
五、得到计算机IP和计算机全名

End Sub
#End Region
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) _ Handles MyBase.Load On Error Resume Next Dim SoundDeviceQuery As New SelectQuery("Win32_CDROMDrive") Dim SoundDeviceSearch As New ManagementObjectSearcher(SoundDeviceQuery) Dim SoundDeviceInfo As ManagementObject For Each SoundDeviceInfo In SoundDeviceSearch.Get() Dim SizeInMBs As Long = (Val(SoundDeviceInfo("Size").ToString())) SizeInMBs = Int((SizeInMBs / (1024 * 1024))) ListBox1.Items.Add("CD-Rom Description: " & SoundDeviceInfo("caption").ToString()) ListBox1.Items.Add("CD-Rom Manufacturer: " & SoundDeviceInfo("Manufacturer").ToString()) ListBox1.Items.Add("CD-Rom Drive: " & SoundDeviceInfo("drive").ToString()) ListBox1.Items.Add("CD-Rom Media Loaded: " & SoundDeviceInfo("MediaLoaded").ToString()) ListBox1.Items.Add("CD-Rom Media Type: " & SoundDeviceInfo("MediaType").ToString()) ListBox1.Items.Add("CD-Rom Volume Name: " & SoundDeviceInfo("VolumeName").ToString()) ListBox1.Items.Add("CD-Rom Size: " & SizeInMBs & " MBytes") ListBox1.Items.Add("CD-Rom Status: " & SoundDeviceInfo("Status").ToString()) ListBox1.Items.Add("CD-Rom MaxMediaSize: " & SoundDeviceInfo("MaxMediaSize").ToString()) ListBox1.Items.Add("CD-Rom Id: " & SoundDeviceInfo("Id").ToString()) ListBox1.Items.Add("CD-Rom TransferRate: "+Int(SoundDeviceInfo("TransferRate").ToString())+" KBs/秒") Next End Sub End Class
八、得到硬盘信息
Imports System.Management Public Class Form1 Inherits System.Windows.Forms.Form
#Region " Windows Form Designer generated code "
Public Sub New() MyBase.New() InitializeComponent() End Sub
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 Private components As System.ComponentModel.IContainer Friend WithEvents ListBox1 As System.Windows.Forms.ListBox Private Sub InitializeComponent() Me.ListBox1 = New System.Windows.Forms.ListBox Me.SuspendLayout() ' 'ListBox1 ' Me.ListBox1.Location = New System.Drawing.Point(8, 8) Me.ListBox1.Name = "ListBox1" Me.ListBox1.Size = New System.Drawing.Size(272, 212) Me.ListBox1.TabIndex = 0 ' 'Form1 ' Me.AutoScaleBaseSize = New System.Drawing.Size(5, 13) Me.ClientSize = New System.Drawing.Size(292, 238) Me.Controls.AddRange(New System.Windows.Forms.Control() {Me.ListBox1}) Me.Name = "Form1" Me.Text = "Form1" Me.ResumeLayout(False)

九、得到声卡信息
Imports System.Management Public Class Form1 Inherits System.Windows.Forms.Form
#Region " Windows Form Designer generated code "
Public Sub New() MyBase.New() InitializeComponent() End Sub
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 Private components As System.ComponentModel.IContainer Friend WithEvents ListBox1 As System.Windows.Forms.ListBox Private Sub InitializeComponent() Me.ListBox1 = New System.Windows.Forms.ListBox Me.SuspendLayout() ' 'ListBox1 ' Me.ListBox1.Location = New System.Drawing.Point(8, 8) Me.ListBox1.Name = "ListBox1" Me.ListBox1.Size = New System.Drawing.Size(272, 212) Me.ListBox1.TabIndex = 0 ' 'Form1 ' Me.AutoScaleBaseSize = New System.Drawing.Size(5, 13) Me.ClientSize = New System.Drawing.Size(292, 238) Me.Controls.AddRange(New System.Windows.Forms.Control() {Me.ListBox1}) Me.Name = "Form1" Me.Text = "Form1" Me.ResumeLayout(False)
End Sub
#End Region
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim SoundDeviceQuery As New SelectQuery("Win32_SoundDevice") Dim SoundDeviceSearch As New ManagementObjectSearcher(SoundDeviceQuery) Dim SoundDeviceInfo As ManagementObject For Each SoundDeviceInfo In SoundDeviceSearch.Get() ListBox1.Items.Add("Sound Device Description: " & SoundDeviceInfo("Caption").ToString()) ListBox1.Items.Add("Sound Device Status: " & SoundDeviceInfo("status").ToString()) ListBox1.Items.Add("Sound Device Manufacturer: " & SoundDeviceInfo("Manufacturer").ToString()) Next End Sub
End Class
