<P></P>这是一个用asp.net写的论坛程序,虽然简单但可以运行。
<P></P>
<P>这个程序的编程思想其实还是基本延续了asp的方式,如果让那只大鸟儿看见可能要嘘之以鼻。但实际上这种方式对于asp程序向asp.net的快速移植还是有用的。如果你对这种移植不屑那也没办法,这个贴子就算给asp.net刚入门的小虾们开开眼。</P>
<P>这个例子包含3部分</P>
<P>1)forum.aspx-论坛主页。</P>
<P>2)reply.aspx-当在论坛主页中点击一个贴子时调用,显示贴子详细内容。</P>
<P>3)postmessage.aspx-上贴时调用,将内容保存入数据库</P>
<P>数据库结构 Table - newpost :This table will contain the New Topic posted messages
<BR>postid (primary key) The unique id for each new topic. <BR>name The name of
the author of the message. <BR>email E-mail address of the author. <BR>subject
Subject of the message. <BR>ip IP address of the author. <BR>date Date / Time of
the Post <BR>message Message posted. <BR>replies Number of replies to the post
(if any) <BR>views Number of times the message has been viewed. </P>
<P><BR>Table - reply :This table will contain the Replies made to the new
topics. <BR>replyid (primary key) The unique id for each reply. <BR>name Name of
the author. <BR>email E-mail address of the author. <BR>subject Subject of the
post <BR>ip IP of the author. <BR>date Date / Time of post. <BR>message Message
posted. <BR>postid postid from the "newpost" table for which this message is a
reply. </P>
