ASP+VML+DB实现投票统计项目
作者：采集员 文章来源：来源于网络 点击数： 更新时间：2005/9/10 12:39:22

       几个月前我看到过一位网友lshdic写的一篇用JS+VML的《使用 Vml 制作立体柱状投票统计图的完整程序》。
       我觉得这个方法非常不错，可以不使用图片就生成统计图，现在就让我们一起来用ASP实现这个程序。

      准备工作：用ACCESS建立一个MDB数据库,名为vote.mdb，并且在数据库中建立如下两个表：



然后建立我们按照ASP开发的惯例建立连接数据库的文件conn.asp
<%
'conn.asp
Set conn=Server.CreateObject("ADODB.Connection")
conn.Open "driver={Microsoft Access Driver (*.mdb)};dbq="& Server.MapPath("vote.mdb")
%>

显示投票项目的列表，因为我们要制作的是一个多项目的投票系统vote_list.asp
<!--#include file="conn.asp"-->
<html>
<head>
<title>投票项目列表</title>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<link href="../images/main.css" rel="stylesheet" type="text/css">
</head>
<%
set rs=conn.execute("select * from votetitle order by voteid desc")
%>
<table border=1 cellspacing="0" style="border-collapse: collapse" cellpadding="0" bgcolor="#ffffff" bordercolor="#000000" width=100%>
  <tr>
    <td bgcolor="#EFEFEF">所有投票列表</td>
  </tr>
  <%do while not rs.eof%>
  <tr>
    <td>编号：<font color="#FF0000"><%=rs("voteid")%>&nbsp; </font><a href="vote.asp?voteid=<%=rs("voteid")%>" target="_blank"><%=rs("votetitle")%>
      </a>(<%=rs("time")%>)</td>
  </tr>
  <%rs.movenext 
loop 
rs.close
set rs=nothing%>
</table>
</body>
</html>

投票显示页面vote_show.asp
<%if request("voteid")="" then
response.write "参数没有指定。"
response.End()
end if%>
