A few months ago, I saw an article written by a netizen lshdic using JS+VML "A complete program to create a three-dimensional columnar voting chart using Vml".
I think this method is very good. It can generate statistical charts without using pictures. Now let us implement this program using ASP.
Preparation: Use ACCESS to create an MDB database named vote.mdb, and create the following two tables in the database:
Then we create the file conn.asp that connects to the database according to the convention of ASP development.
<%
'conn.asp
Set conn=Server.CreateObject("ADODB.Connection")
conn.Open "driver={Microsoft Access Driver (*.mdb)};dbq="& Server.MapPath("vote.mdb")
%>
Display the list of voting projects, because what we want to make is a multi-project voting system vote_list.asp
<!--#include file="conn.asp"-->
