在VB中使用WMI获取系统硬件和软件有关信息

简介:

      WMI是英文Windows Management
      Instrumentation的简写，它的功能主要是：访问本地主机的一些信息和服务，可以管理远程计算机（当然你必须要拥有足够的权限），比如：重启，关机，关闭进程，创建进程等。

实例如下:

'用WMI,先工程-引用 Microsoft WMI Scripting V1.1 Library

    获取显卡/声卡/内存/操作系统的信息

   声卡信息

Private Sub wmiSoundDeviceInfo()

   Dim wmiObjSet As SWbemObjectSet
   Dim obj As SWbemObject
  
   Set wmiObjSet = GetObject("winmgmts:{impersonationLevel=impersonate}"). _
                          InstancesOf("Win32_SoundDevice")
   On Local Error Resume Next
  
   For Each obj In wmiObjSet
      MsgBox obj.ProductName
   Next
End Sub

显卡信息

Private Sub wmiVideoControllerInfo()

   Dim wmiObjSet As SWbemObjectSet
   Dim obj As SWbemObject
  
   Set wmiObjSet = GetObject("winmgmts:{impersonationLevel=impersonate}"). _
                          InstancesOf("Win32_VideoController")
  
   On Local Error Resume Next
  
   For Each obj In wmiObjSet
      MsgBox obj.VideoProcessor
   Next
End Sub

内存信息

Private Sub wmiPhysicalMemoryInfo()

   Dim wmiObjSet As SWbemObjectSet
   Dim obj As SWbemObject
  
   Set wmiObjSet = GetObject("winmgmts:{impersonationLevel=impersonate}"). _
                          InstancesOf("Win32_PhysicalMemory")
  
   On Local Error Resume Next
  
   For Each objItem In wmiObjSet
        Debug.Print "BankLabel: " & objItem.BankLabel
        Debug.Print "Capacity: " & objItem.Capacity
        Debug.Print "Caption: " & objItem.Caption
        Debug.Print "CreationClassName: " & objItem.CreationClassName
        Debug.Print "DataWidth: " & objItem.DataWidth
        Debug.Print "Description: " & objItem.Description
        Debug.Print "DeviceLocator: " & objItem.DeviceLocator
        Debug.Print "FormFactor: " & objItem.FormFactor
        Debug.Print "HotSwappable: " & objItem.HotSwappable
        Debug.Print "InstallDate: " & objItem.InstallDate
        Debug.Print "InterleaveDataDepth: " & objItem.InterleaveDataDepth
        Debug.Print "InterleavePosition: " & objItem.InterleavePosition
        Debug.Print "Manufacturer: " & objItem.Manufacturer
        Debug.Print "MemoryType: " & objItem.MemoryType
        Debug.Print "Model: " & objItem.Model
        Debug.Print "Name: " & objItem.name
        Debug.Print "OtherIdentifyingInfo: " & objItem.OtherIdentifyingInfo
        Debug.Print "PartNumber: " & objItem.PartNumber
        Debug.Print "PositionInRow: " & objItem.PositionInRow
        Debug.Print "PoweredOn: " & objItem.PoweredOn

        Debug.Print "TotalWidth: " & objItem.TotalWidth
        Debug.Print "TypeDetail: " & objItem.TypeDetail
        Debug.Print "Version: " & objItem.Version
   Next
End Sub

操作系统信息

Private Sub Command1_Click()
    Dim wmiObjSet As SWbemObjectSet
    Dim obj As SWbemObject
    Dim msg As String
    Dim dtb As String
    Dim d As String
    Dim t As String
    Dim bias As Long
    On Local Error Resume Next
    Set wmiObjSet = GetObject("winmgmts:{impersonationLevel=impersonate}").InstancesOf("Win32_OperatingSystem")
    For Each obj In wmiObjSet
        MsgBox "你当前使用的系统是 " & obj.Caption
    Next
End Sub

说明:

大家可能会发现一个规律,实际上WMI对信息的提取都是使用了WIN32_类库名这样的规律,下列表格就是微软的操作系统各种硬件类的描述

其它WMI管理的类的信息在

可以找到,其中也还有部分示例代码

Win32 Classes

Microsoft® Windows® classes give you the means to manipulate a variety of objects. The following table identifies the categories of Windows classes.

Category Description Computer system hardware Classes that represent hardware related objects. Operating system Classes that represent operating system related objects. Installed applications Classes that represent software related objects. WMI service management Classes used to manage WMI. Performance counters

Classes that represent formatted and raw performance data.

硬件类

Computer System Hardware Classes

he Cooling Devices subcategory groups classes that represent instrumentable fans, temperature probes, and refrigeration devices.

Class Description Win32_Fan Represents the properties of a fan device in the computer system. Win32_HeatPipe Represents the properties of a heat pipe cooling device. Win32_Refrigeration Represents the properties of a refrigeration device. Win32_TemperatureProbe Represents the properties of a temperature sensor (electronic thermometer).

Input Device Classes

The Input Devices subcategory groups classes that represent keyboards and pointing devices.

Class Description Win32_Keyboard Represents a keyboard installed on a Windows system. Win32_PointingDevice Represents an input device used to point to and select regions on the display of a Windows computer system.
