请高手帮我讲解一下！下面代码是什么意思？重点讲解下on error resume next和 For each next的用法！
<%
on error resume next
For each drv in fso.Drives
Response.Write "<tr>"
Response.Write "<td>" & drv.DriveLetter & "</td>"
Response.write "<td>" & tran(drv.DriveType) & "</td>"
Response.write "<td>" & drv.VolumeName & "</td>"
Response.write "<td>" & FormatNumber(drv.TotalSize / 1024, 0)& "</td>"
Response.write "<td>" & FormatNumber(drv.Availablespace / 1024, 0) & "</td>"
Response.write "<td>" & drv.FileSystem & "</td>"
Response.write "<td>" & drv.SerialNumber & "</td>"
Response.write "<td>" & drv.IsReady & "</td>"
Response.write "<td>&quo

on error resume next
For each drv in fso.Drives
Response.Write "<tr>"
Response.Write "<td>" & drv.DriveLetter & "</td>"
Response.write "<td>" & tran(drv.DriveType) & "</td>"
Response.write "<td>" & drv.VolumeName & "</td>"
Response.write "<td>" & FormatNumber(drv.TotalSize / 1024, 0)& "</td>"

Response.write "<td>" & drv.FileSystem & "</td>"
Response.write "<td>" & drv.SerialNumber & "</td>"
Response.write "<td>" & drv.IsReady & "</td>"
Response.write "<td>&quo
on error resume next遇到错误时,继续执行后面的代码,不显示出错信息.
for each 变量 in 对象集
代码
next
遍历对象的每一个元素,进行循环.
常用于对一个数组或控件集合进行循环检索判断.
drv in fso.Drives
fso.drives 是用fso对象获取服务器上的每一个驱动器.
然后用 drv 取代它的单个值.
on error resume next遇到错误则继续执行后面的代码!
For each nex遍历数组中的各个对象!
