To test, well just try to show all files with a .GIF extension in the root of C:
Set objFSO = createObject("Scripting.FileSystemObject")

Set objFC = objF.Files
response.write "<table border=""0"" cellpadding=""5"">"
For Each f1 in objFC
if instr(ucase(f1.Name), ".GIF") then
response.write "<tr><td>" & f1.name & "</td><td>" & f1.Datecreated & "</td><td>" & f1.Size & "</td><td>"
if gfxSpex(f1.Path, w, h, c, strType) = true then
response.write w & " x " & h & " " & c & " colors"
else
response.write " "
end if
response.write "</td></tr>"

29.分页代码:
<%本程序文件名为：Pages.asp%>
<%包含ADO常量表文件adovbs.inc，可从"\Program Files\Common Files\System\ADO"目录下拷贝%>
<!--#Include File="adovbs.inc"-->
<%＊建立数据库连接，这里是Oracle8.05数据库
Set conn=Server.createObject("ADODB.Connection")
conn.Open "Provider=msdaora.1;Data Source=YourSrcName;User ID=YourUserID;Password=YourPassword;"
Set rs=Server.createObject("ADODB.Recordset") 创建Recordset对象
rs.CursorLocation=adUseClient 设定记录集指针属性
＊设定一页内的记录总数，可根据需要进行调整
rs.PageSize=10
＊设置查询语句
StrSQL="select ID,姓名,住址,电话 from 通讯录 Order By ID"
rs.Open StrSQL,conn,adOpenStatic,adLockReadOnly,adCmdText
