其实没有题目写得那么复杂，就是用计划任务每隔一段时间调用VBS脚本，刷新生成一个文件列表文件用于WEB服务调用。
代码如下:
Option Explicit
On Error Resume Next
'生成列表的文件类型
Const sListFileType = "wmv,rm,wma"
'文件所在的相对路径
Const sShowPath="."
'排序类型的常量定义
Const iOrderFieldFileName = 0
Const iOrderFieldFileExt = 1
Const iOrderFieldFileSize = 2
Const iOrderFieldFileType = 3
Const iOrderFieldFileDate = 4
'排序顺逆的常量定义
const iOrderAsc = 0
const iOrderDesc = 1
'生成列表的文件数量
const iShowCount = 20
'显示的日期格式函数
Function Cndate2(date1,intDateStyle)
dim strdate,dDate1
strdate=cstr(date1)
If Isdate(strdate) Then
If Left(cstr(strdate),1)="0" Then
dDate1=Cdate("20"+cstr(strdate))
else
dDate1=Cdate(strdate)
End If
Else
