Question

我正在使用以下代码捕获在目录中创建的文件：

strComputer = "."
strQueryFolder = Replace(strFolder, "\", "\\\\")
Set objWMIService = GetObject("winmgmts:" & "{impersonationLevel=impersonate}!\\" &     strComputer & "\root\cimv2") 
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该文件。

如何识别写文件的完成情况？

我记得我像这样制作了Vbscript，你可以看看这段代码

我希望这可以帮助你并给你更多的想法。
