使用 VB 脚本监控目录 [英] Monitoring directory with VB Script
本文介绍了使用 VB 脚本监控目录的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我使用下面的代码来捕获在目录中创建的文件:
I'm using the code below to capture a file created in a directory:
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正在捕获文件.
The problem is that the script is capturing the file while it is being written to the directory.
如何判断写文件完成?
推荐答案
我记得我是这样做 à Vbscript 的,你可以看看这段代码
I remember that i made à Vbscript like that , you can take a look at this code
