要求：
能够读取按照 INI文件的Section和Key来读出相应的Value。
比如一个配置文件
SMSVote.ini
---------------------------------
[SMSVote]
Server=(local)
DB=SMSVote
User=sa
PassWord=123
[DB2Vote]
Server=192.168.0.1
DB=DB2
User=sa
PassWord=
---------------------------------

主体程序（方法）：

inifile.asp
-----------------------------------------------
<%
set IniFileDictionary = CreateObject("Scripting.Dictionary")

Sub IniFileLoad(ByVal FilSpc)
   IniFileDictionary.RemoveAll
   FilSpc = lcase(FilSpc)
   if left(FilSpc, 1) = "p" then
       'Physical path
       PhyPth = mid(FilSpc, instr(FilSpc, "=") + 1)
   else
       'Virtual path
       PhyPth = Server.MapPath(mid(FilSpc, instr(FilSpc, "=") + 1))
   end if

   set FilSys = CreateObject("Scripting.FileSystemObject")
   set IniFil = FilSys.OpenTextFile(PhyPth, 1)
   do while not IniFil.AtEndOfStream
       StrBuf = IniFil.ReadLine
       if StrBuf <> "" then
           'There is data on this line
           if left(StrBuf, 1) <> ";" then
               'It's not a comment
               if left(StrBuf, 1) = "[" then

如何使用？

看看这个：
conn.asp
-----------------------------------------------


<%
         on error resume next
         dim conn,connstr,dbuid,dbpwd,dbname,dbip
         call IniFileLoad("virtual=SMSVote.ini") '配置文件的名字
         dbuid=Chr("SMSVote","User")            'Section="SMSVote",Key="User"
         dbpwd=Chr("SMSVote","PassWord")    'Section="SMSVote",Key="PassWord"
         dbname=Chr("SMSVote","DB")              'Section="SMSVote",Key="DB"
         dbip=Chr("SMSVote","server")          'Section="SMSVote",Key="server"

set conn=Server.CreateObject("adodb.Connection")
connstr="PROVIDER=SQLOLEDB;DATA SOURCE="&dbip&";UID="&dbuid&";PWD="&dbpwd&";DATABASE="&dbname
conn.open connstr
'response.write conn
response.write err.description
%>
