主要功能为：在聊天室中，每隔5分钟，向显示对话页面，发送一道题，所有用户都可答题。
答对者加相应的分值。
具体实现：在聊天室框架中加入一隐含帧，
此帧每5分钟刷新一次。
隐含帧内的asp页内容如下：
<%@ language=vbscript%>
<%response.expires=0%>
<%
dim conn,rs
application.lock
application("canswername")=application("answername") '保存答对题用户的名字
application("answername")=""
application("tanswername")="" '清除答错题用户的名子
set conn=server.createobject("adodb.connection")
accessdb="db1.mdb" '题库的连接
mydsn="driver={microsoft access driver (*.mdb)};"
mydsn=mydsn & "dbq=" &server.mappath(accessdb)
conn.open mydsn
set rs = server.createobject("adodb.recordset")
rs.cursorlocation=3
rs.open "select * from question ",conn
randomize '随机取得一道题的id
r=rs.recordcount
id=int((r-1)*rnd)+1
rs.close
set rs=nothing
set rs = server.createobject("adodb.recordset")
rs.open "select * from question where questionid="&id,conn
application("questionname")=rs("questionname") '题目
application("questionid")=rs("questionid") '题的id
application("questioncent")=rs("questioncent") '题的分数
application("questionclass")=rs("questionnotes")'题的说明
rs.close
set rs = nothing
set ra = server.createobject("adodb.recordset")
ra.open "select * from answer where questionid="&id,conn
application("answera")=ra("answera") '题的选项
application("answerb")=ra("answerb")
application("answerc")=ra("answerc")
application("answerd")=ra("answerd")
application("answertrue")=ra("answertrue") '题的正确答案
ra.close
set ra=nothing
conn.close
set conn=nothing
application("questiontime")=now()
application.unlock

答案处理部分，放在处理发送对话信息的程序中即可。下面是答案处理的代码部分：
if mid(fstr,i,1)="#" then 'fstr是保存对话信息的字符串变量
tfstr=mid(fstr,i+1,1)
if cint(datediff("n",application("questiontime"),now()))<=1 then '判断时间1分钟内答题有效
if lcase(tfstr)=lcase(application("answertrue")) then '判断答题是否正确
if instr(1,application("answername"),session("user_username"))>0 then '判断用户是否已经答过题了
tfstr=session("user_username")&"已经答过这道了！！！"
else
tfstr=session("user_username")&"答题正确！"
session("user_exp") =session("user_exp")+application("questioncent") '给答对题的用户加分
application("answername")=application("answername")&session("user_username")&" " '保存答对题用
户的名字
end if
else
if instr(1,application("tanswername"),session("user_username"))>0 then ''判断用户是否已经答过题
了
tfstr=session("user_username")&"已经答过这道了！！！"
else
application("tanswername")=application("tanswername")&session("user_username")&" " '保存答错题用
户的名字
end if
end if
end if |
