如果你使用过大部分，那么你的ASP功力应该是非常高的了

ADO对象(太常用了)：
Connection
Command
RecordSet
Record
Stream

ASP支持的对象太多了，你可以自己写COM组件，下面是我们经常使用的：
Server.CreateObject("Scripting.FileSystemObject")
Server.CreateObject("Scripting.Dictionary")  HashTable
Server.CreateXObject("Word.Application")   //Server
ActiveXObject("Word.Application")   //Client
Server.CreateObject("Excel.Application")  //Server
ActiveXObject("Excel.Application")   //Client
CreateObject("PowerPoint.Application")
Server.CreateObject("Microsoft.XMLHTTP")
Server.CreateObject("Microsoft.XMLDOM")
Server.CreateObject("MSXML2.XMLHTTP.4.0")
Server.CreateObject("WScript.Shell")
Server.CreateObject("wscript.network") //网络地址的
Server.CreateObject("MSWC.AdRotator")
CreateObject("Excel.Sheet")
MS FrontPage: oFP = CreateObject("FrontPage.Application")
MS Access: oAccess = CreateObject("Access.Application")
MS Graph: oGraph = CreateObject("MSGraph.Application")

下面是我们应该知道的：

CreateObject("PhotoShop.Application")

//关于SQL Server的
CreateObject("SQLDMO.SQLServer")
CreateObject("SQLDMO.Login")
CreateObject("SQLDMO.Backup")
CreateObject("SQLDMO.User")
Server.CreateObject("SQLDMO.BackupDevice")
Server.CreateObject("SQLDMO.Database")
Server.CreateObject("SQLDMO.Restore")
具体的例子请看下面的连接
http://www.asp101.com/articles/carvin/sqldmobackup/default.asp

//MSMQ的
Server.CreateObject("MSMQ.MSMQQueueInfo")
CreateObject("MSMQ.MSMQQuery")
//全文索引的
Server.CreateObject("ixsso.Query")
Server.CreateObject("ixsso.Util")
邮件发送的组件我没有总结，请热心的朋友总结出来：
CDO,Jmail,Imail等。
