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 %> <HTML> <head> <meta http-equiv='Content-Type' content='text/html; charset=gb2312'> <Link Rel='stylesheet' Href='../Style.Css' Type='text/css'> <meta http-equiv="refresh" content="300;url=question.asp"> <title><%=Application("V")%></title> <script Language="JavaScript"> parent.ShowSays.document.write("******系统消息:******<br>"); //向聊天室显示对话窗口写入问题 parent.ShowSays.document.write("**上题答对者为:<%=application"CanswerName")%><br>"); parent.ShowSays.document.write("问题::<%=application("questionName")%>"); parent.ShowSays.document.write(" <%=application("questionCent")%>分(1分钟之内,回答输入‘#答案’)<%=Time()%><br>"); parent.ShowSays.document.write("A::<%=application("answerA")%><br>"); parent.ShowSays.document.write("B::<%=application("answerB")%><br>"); parent.ShowSays.document.write("C::<%=application("answerC")%><br>"); parent.ShowSays.document.write("D::<%=application("answerD")%><br>"); </script> </head> <body bgcolor='#FFFFFF'> </Body> </html> 处理答题部分略!!! 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
