vbscript - 如何通过vbs监控文件夹文件

Question

谁能帮我在哪里出错？此脚本用于监视文件夹以创建、删除或修改文本文件

sPath = "C:\scripts\test"
sComputer = "."
sDrive = split(sPath,":")(0)
sFolders1 = split(sPath,":")(1)
sFolders = REPLACE(sFolders1, "\", "\\") & "\\"

Set objWMIService = GetObject("winmgmts:\\" & sComputer & "\root\cimv2")
Set colMonitoredEvents = objWMIService.ExecNotificationQuery _
("SELECT * FROM __InstanceOperationEvent WITHIN 1 WHERE " _
& "TargetInstance ISA 'CIM_DataFile' AND " _
& "TargetInstance.Drive='" & sDrive & "' AND " _
& "TargetInstance.Path='" & sFolders & "' AND " _
& "TargetInstance.Extension = 'txt' ")

Wscript.Echo vbCrlf & Now & vbTab & _
"Begin Monitoring for a Folder " & sDrive & ":" & sFolders1 & " Change Event..." & vbCrlf

Do
    Set objLatestEvent = colMonitoredEvents.NextEvent
    Select Case objLatestEvent.Path_.Class

    Case "__InstanceCreationEvent"
    WScript.Echo Now & vbTab & objLatestEvent.TargetInstance.FileName & "." & objLatestEvent.TargetInstance.Extension _
    & " was created" & vbCrlf

    Case "__InstanceDeletionEvent"
    WScript.Echo Now & vbTab & objLatestEvent.TargetInstance.FileName & "." & objLatestEvent.TargetInstance.Extension _
    & " was deleted" & vbCrlf

    Case "__InstanceModificationEvent"
    If objLatestEvent.TargetInstance.LastModified <> _
    objLatestEvent.PreviousInstance.LastModified then
    WScript.Echo Now & vbTab & objLatestEvent.TargetInstance.FileName & "." & objLatestEvent.TargetInstance.Extension _
    & " was modified" & vbCrlf
    End If
    End Select
Loop

Set objWMIService = nothing
Set colMonitoredEvents = nothing
Set objLatestEvent = nothing

这个脚本在我写的时候运行完美

sPath = "\\ComputerName\C$\scripts\test"

安装的

sPath = "C:\scripts\test"

谢谢....

如果你用 google 搜索"WMI TargetInstance.Drive"，你会看到驱动器号需要一个冒号。像这样的查询

SELECT * FROM __InstanceOperationEvent WITHIN 1 WHERE TargetInstance ISA 'CIM_DataFile' AND TargetInstance.Drive='E:' AND TargetInstance.Path='\\trials\\SoTrials\\answers\\10041057\\data\\' AND TargetInstance.Extension = 'txt'

按预期工作。
