参考代码一：
复制代码 代码如下:
Function DeleteLog( )
Dim objFSO, objFolder, strPath, targetFSO, subFSO, DirPath
DirPath = createobject("Scripting.FileSystemObject").GetFile(Wscript.ScriptFullName).ParentFolder.Path&"\Log\"
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set targetFSO = objFSO.GetFolder(DirPath)
Set subFSO = targetFSO.SubFolders

For Each subFolder in SubFSO
If DateDiff("d", subFolder.name, date)>3 Then
strPath = DirPath&subFolder.name
objFSO.DeleteFolder(strPath)
End If
Next
End Function
Call DeleteLog( )
这样在task Schdeuler里面schedule我的vbs程序就没有报错啦。撒花，结贴~~
