使用filesystemobject，可以对服务器上的文件进行操作，浏览、复制、移动、删除等。有ado的支持，asp对数据库的操作非常得心应手。你甚至可以像使用本地数据库那样，管理远程主机上的数据库，对表格、记录进行各种操作。上回曾贴一篇较复杂的用ASP＋RDS客户端参生报表
此回贴一篇较庞杂的用ASP＋RDS＋组件客户端参生报表
毛病申明：(若提醒ActiveX 元件没法参生 RDS.DataSpace)
IE需设置平安选项
操作：菜单东西->INTERNET选项->平安性->自界说
设置：肇端但ActiveX不标示为平安->开启
道理申明：
客户端直接用RDS发生RecordSet平安性不敷，利用了
middle-tier Automation components 后可大大增添平安性！
请看下文：
编写注册元件：
ActiveX Dll project:iacrdsobj.vbp
Class Module name:RsOp

Public Function ReturnRs(strDB As Variant, strSQL As Variant) As ADODB.Recordset
'Returns an ADODB recordset.
On Error GoTo ehGetRecordset
Dim cn As New ADODB.Connection
Dim rs As New ADODB.Recordset
Dim strConnect As String
strConnect = "Provider=SQLOLEDB;Server=server name ;uid=sa;pwd=; Database=" & strDB & ";"
cn.Open strConnect
'These are not listed in the typelib.
rs.CursorLocation = adUseClient
'Using the Unspecified parameters, an ADO/R recordset is returned.
rs.Open strSQL, cn, adOpenUnspecified, adLockUnspecified, adCmdUnspecified
Set ReturnRs = rs
Exit Function
ehGetRecordset:
Err.Raise Err.Number, Err.Source, Err.Description
End Function
然后 MAKE iacrdsobj.dll
如有错，请设置VB菜单PROJECT－REFREENCE
增添 MicroSoft ActiveX Data Object 2.6 Library(固然数字要高一点)

然后注册iacrdsobj.dll到数据库server(为平安，最好更改数据库uid最好不为sa)！
好，接上去看asp

帮助用户快速实现各种应用服务，ASP商有整合各方面资源的能力，可在短期内为用户提供所需的解决方案。例如，典型的ERP安装，如果要在客户端安装的话需要半年到二年的时间，但是美国的一些ASP商如USI和CORIO能在90—120天内提供ERP应用方案。

从事这个行业，那么你可以学ASP语言，简单快速上手，熟练dreamweav排版，写asp代码，熟练photoshop处理图片，打好基础就行了
