用VB脚本监控目录

Question

我使用下面的代码来捕获在目录中创建的文件:

strComputer = "."
strQueryFolder = Replace(strFolder, "", "\\")
Set objWMIService = GetObject("winmgmts:" & "{impersonationLevel=impersonate}!\" &     strComputer & "rootcimv2") 
Set colMonitoredEvents = objWMIService.ExecNotificationQuery ("SELECT * FROM __InstanceCreationEvent WITHIN " & nFrequency & " WHERE Targetinstance ISA 'CIM_DirectoryContainsFile' and TargetInstance.GroupComponent='Win32_Directory.Name=""" & strQueryFolder & """'") 
Do 
    Set objLatestEvent = colMonitoredEvents.NextEvent
    strNewFile = objLatestEvent.TargetInstance.PartComponent
    arrNewFile = Split(strNewFile, "=")
    strFilePath = arrNewFile(1)
    strFilePath = Replace(strFilePath, "\", "")
    strFilePath = Replace(strFilePath, Chr(34), "")
    strFileName = Replace(strFilePath, strFolder, "")
    strTempFilePath = WScript.CreateObject("Scripting.FileSystemObject").GetSpecialFolder(2) & "TEMP.M4A"
    'Do something with strTempFilePath 
Loop

问题是脚本在将文件写入目录时捕获了该文件。

如何识别文件写入完成?

我记得我做过这样的 Vbscript，你可以看看这段代码

我希望能帮助你，给你更多的想法。
