RONG>在VB中使用WMI获取系统硬件和软件Software有关信息

介绍:

WMI是英文Windows Management
Instrumentation简写它功能主要是:访问本地主机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权限)比如:重启关机关闭进程创建进程等

例子如下:

´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\")
_disibledevent=> InstancesOf(\"Win32_VideoController\")

_disibledevent=> InstancesOf(\"Win32_PhysicalMemory\")

_disibledevent=>


Debug.Pr \"TypeDetail: \" & objItem.TypeDetail
Debug.Pr \"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
_disibledevent=> For Each obj In wmiObjSet
MsgBox \"你当前使用系统是 \" & obj.Caption
Next
End Sub

介绍说明:

大家可能会发现个规律,实际上WMI对信息提取都是使用了WIN32_类库名这样规律,下列表格就是微软操作系统各种硬件类描述

其它WMI管理类信息在



可以找到,其中也还有部分举例代码

Win32_SoundDevice : CIM_LogicalDevice
{
u16 ;
;
u32 ;
boolean ;
;
;
;
u16 ;
boolean ;
;
datetime ;
u32 ;
;
u32 ;
;
;
u16 ;
boolean ;
;
;
u16 ;
;
;
};

Win32_PrJob : CIM_Job
{
;
;
;
;
;
datetime ;
;
datetime ;
u32 ;
;
;
;
;
u32 ;
;
;
u32 ;
u32 ;
datetime ;
;
u32 ;
datetime ;
u32 ;
datetime ;
};

如

Set wmiObjSet = GetObject(\"winmgmts:{impersonationLevel=impersonate}\"). _
InstancesOf(\"Win32_PrJob\")

可以获得打印任务列表等信息



对于VB来讲获得系统硬件和软件Software信息大都使用API,现在使用WMI可以快速实现我们目标.如获取驱动器/显卡/共享信息等等都会变得方便和有效
