Question

User-1578974752 posted

The project in online Test. Now my issue is :

There are 3 pages in the Test . Users are not allowed to go back or click page 1 once they go to the second page.

The problem is that,if the user is in 3rd page, then they copy the link and paste in in another page means start button is showing for them to start.once they click 1,2,and 3 pages are showing and they can re do the test.

how can I prevent ,if they copy the link separately to another page how can I force them to login page?

As I am using Datapager for page control. where should I place the Response.redirect("login.aspx") code

Appreciate the help

Hi,

I would start by preventing direclty what I want to prevent (ie don't update the db with answsers if you already have anwssers for this user). Here it seems you are trying to pvent them to do bad things by keeping them away from a page that allows them to do something you don"t want...

First page is having only a start button. If the user ,click start button,3 pages will be shown each page with 5 questions.Once the user press save on first page -> 5 questions with answers will be inserted to a table along with the userid. they can not go back in any way to see page 1 if they are in page 2. same for second and 3rd page. once click finish button,the answers of the 15 inserted questions will be compared with the correct answers in master table,will get marks if it is correct.

Now when the user copy the link to another page means, page with start button is showing ,so that they can click the start button again and 3 pages can be seen and can do the test again.

I have tried, with

if session value is “ ” then response.redirect (“login.aspx”)

but this is not working. session time out need to be 30 min, I cannot change it.

In the page load,only start button is there.Once the user click start then they can see the first page .

Here which ever page is copying to another explorer they can see the start button and can re-do the test.

listview is used with datapager.

<asp:Datapager ID="dtpgr" runat="server" pagedcontrolid="ListView1" Pagesize="5">

 

 

    

           <Fields>

               <asp:NumericPagerFieldButtonCount="5"

 

           NumericButtonCssClass="numeric_button"

 

           CurrentPageLabelCssClass="current_page"

 

           NextPreviousButtonCssClass="next_button" />

           </Fields>

       </asp:DataPager>

Hi shsu,

You could use session.You could set  the timeout in web.config.

<system.web>
  　　<sessionState mode="InProc" timeout="120"/>
  　　</system.web>　

Below is my code.

 Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        If Not IsPostBack Then
            Dim record = Session("record")
            If record Is Nothing Then
                Session("record") = "have started"

            Else
                Response.Write("you have started the exam")
                Response.End()
            End If
        End If
    End Sub

The result.

Best regards,

Actually by using ur code,,i could restrict the user from copying the link. But after finishing the test ,when they try to take another test, "you have started the Test is showing"

How to solve that. Appreciate the Help

Don't use the same session value name for each exam. Change the code to use a different name, depending on what exam it is, not to use "record" for all of them.  Three exams?  Use something like exam1, exam2, exam3 (your choice).

Hi shsu,

You should specify the columns you want to get from your table.

select TOP 15 * FROM UserDetail where UserTestID ='1209' ORDERBY ASC
