asp数据连接库代码

这是我经常用的asp数据库连接代码,拿出来当然不是为了什么喽,只希望给初学者一些帮助,因为我记得我刚学时这个连接也搞一半天时间啊.

<%
Dim Rs,Conn//这里申明一下,必须在函数或过程外面申明,要不然会定义无效,原因是变量的全局和私有变量的原因了.

Sub Db_connect()//建立连接
  Dpath ="data\db1.mdb"
  Set Conn=Server.CreateObject("Adodb.connection")
  Set Rs =Server.CreateObject("Adodb.Recordset")
  Conn.connectionstring="Provider=Microsoft.Jet.oledb.4.0;Data source="&Server.MapPath(Dpath)
  Conn.open
End sub

sub closedb()//关闭连接
  if isobject(Rs) then
   if not(Rs is nothing) then
    Rs.close
    set Rs=nothing
    end if
   end if
  if isobject(Conn) then
   if not(Conn is nothing) then
    Conn.close
    set Conn=nothing
   end if
  end if
end sub

'*********************************************************

function html_encode(html)//这里是进行基本的过滤函数,这个可以把textarea里面的回车替换成换行
  dim temp
  temp=replace(html,"<","<")
  temp=replace(temp,">",">")
  temp=replace(temp,"'","单引号")
  temp=replace(temp,chr(13),"<br>")
  html_encode=replace(temp,chr(32)," ")
end function

function encode_html(html)//这个刚好和上面个函数相反还原数据.

dim temp
  temp=replace(html,"<","<")
  temp=replace(temp,">",">")
  temp=replace(temp,"单引号","'")
  temp=replace(temp,chr(13),"<br>")
  encode_html=replace(temp,chr(32)," ")
end function
%>
