 Random Display of Records
Hi all,
I am doing a simple program which display random records to students.The student table has the following fields(Access Database)
Code:
1.Studentid-Number
2.Studentname-Text
3.Class-Text
4.Ans-Text
and Question table as
Code:
1.Questionid-Number
2.Questions-Text
Now What i am trying to do is , when the first time is student is login,he wil be shown a random record from the question and his answered wil be stored in the Ans field of the student table with column separeated.The he will be redirected to the same page with one new question.This question should not be in the Ans Field, and must be randomly generated.I am using this code.But this not working.Can some body help.

Re: Random Display of Records
Without looking real close, this loop will never run since you are setting you are setting isinvalid to false before hitting the loop.
Code:
if rsresults.EOF=false then
Response.Write("Records" & rsresults("ans"))
answeredquestions=split(rsresults("ans"),",")
'Loop through the returned answers and check whether the the
'Question is answered or not
isvalid=false
rndnumber=RandomNumber(50)
' Response.Write("number" & rndnumber)
do while isvalid=true
rndnumber=RandomNumber(50)
for icount=lbound(answeredquestions) to ubound(answeredquestions)
if cint(rndnumber)=cint(answeredquestions(icount)) then
isvalid=true
else
isvalid=false
end if
next
loop
End if
