因为项目需要，所以从网上找了一个类，但是那个类问题比较多，所以自己修改了一下，增加容错程度，提升一些性能，里面有部分代码是根据我的项目修改的，所以大家在使用的时候自己改一下就可以了。
使用方法：
<%On Error Resume Next%>

<!--#include file="../Include/Config.Class.asp"-->
<!--#include file="../Include/DBControl.Class.asp"-->
<!--#include file="../Include/FunctionLib.Class.asp"-->
<!--#include file="../Include/Manager.Class.asp"-->
<!--#include file="../Include/Export2Excel.Class.asp"-->
