我们不做你的作业：它是有原因的。它就是为了让你思考你被告知的事情，并试着理解它。它也在那里，以便您的导师可以识别您身体虚弱的区域，并将更多的注意力集中在补救措施上。



亲自尝试，你可能会发现它不是和你想的一样困难！

现在这就是我在Karthik给出的帮助下解决它的方式：

 受保护的  Sub  Timer1_Tick（ ByVal 发​​件人作为 对象， ByVal  e  As  System.EventArgs）句柄 Timer1.Tick 
 
  Dim  timer_arr（） As   String  
  Dim  timer  As   String  
 timer = Button1.Text 
 
 timer_arr = timer.Split（ ： ）
会话（  seconds）=  Integer  .Parse（timer_arr（ 2 ））
  Dim  minutes = 整数 .Parse（timer_arr（ 1 ））
  Dim  hours = 整数 .Parse（timer_arr（ 0 ））
 如果会话（  seconds） =  0  和 minutes =  0  和 hours =  0  然后 
 Timer1.Enabled = 错误 
 其他 
 Session（  seconds）= Session（ 秒） -   1  
 结束 如果 
 如果（会话（  seconds）<  0 ）然后 
会话（ 秒）=  59  
会话（  minutes）=会话（ 分钟） -   1  
 结束 如果 
 如果会话（ 分钟）<  0  然后 
会话（ 分钟）=  59  
会话（   TimerRemaining）=会话（  TimerRemaining） -   1  
 结束 如果 
 
 Button1.Text = Session（  TimerRemaining）。ToString（）&  ：&会话（  Minutes）。ToString&  ：&会话（  Seconds）。ToString 
 
 如果会话（  TimerRemaining）=  0  和会话（ 分钟）=  0  和会话（ 秒）=  0  然后 
 Button1.Enabled =  False  
 Timer1.Enabled =  False  
 结束 如果 
 结束  Sub  

<前l ang =vb> 受保护的 Sub Page_Load（ ByVal sender 作为 对象， ByVal e As System.EventArgs）句柄 我 .Load


如果 不 IsPostBack 然后
会话（ TimerRemaining）= < span class =code-digit> 1
Session（ Minutes）= 0
会话（ 秒）= 0
对接on1.Text = Session（ TimerRemaining）。ToString（）& ：&会话（ Minutes）。ToString& ：&会话（ Seconds）。ToString

I need a code for putting a timer on aN ASP.NET page to check the time as you write an examination online. The code should be in Vb.net. And postback shouldn''t restart the timer

Hi,

hope it helps

We do not do your homework: it is set for a reason. It is there so that you think about what you have been told, and try to understand it. It is also there so that your tutor can identify areas where you are weak, and focus more attention on remedial action.

Try it yourself, you may find it is not as difficult as you think!

Now this is the way I solved it with the help given me above by Karthik:

Protected Sub Timer1_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Handles Timer1.Tick

       Dim timer_arr() As String
       Dim timer As String
       timer = Button1.Text

       timer_arr = timer.Split(":")
       Session("seconds") = Integer.Parse(timer_arr(2))
       Dim minutes = Integer.Parse(timer_arr(1))
       Dim hours = Integer.Parse(timer_arr(0))
       If Session("seconds") = 0 And minutes = 0 And hours = 0 Then
           Timer1.Enabled = False
       Else
           Session("seconds") = Session("seconds") - 1
       End If
       If (Session("seconds") < 0) Then
           Session("seconds") = 59
           Session("minutes") = Session("minutes") - 1
       End If
       If Session("minutes") < 0 Then
           Session("Minutes") = 59
           Session("TimerRemaining") = Session("TimerRemaining") - 1
       End If

       Button1.Text = Session("TimerRemaining").ToString() & ":" & Session("Minutes").ToString & ":" & Session("Seconds").ToString

       If Session("TimerRemaining") = 0 And Session("minutes") = 0 And Session("seconds") = 0 Then
           Button1.Enabled = False
           Timer1.Enabled = False
       End If
   End Sub

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load


        If Not IsPostBack Then
            Session("TimerRemaining") = 1
            Session("Minutes") = 0
            Session("Seconds") = 0
            Button1.Text = Session("TimerRemaining").ToString() & ":" & Session("Minutes").ToString & ":" & Session("Seconds").ToString
        End If
   End Sub

<form id="form1" runat="server">

                        <div>
        <asp:ScriptManager ID="ScriptManager1" runat="server">
        </asp:ScriptManager>
        <asp:UpdatePanel ID="UpdatePanel1" runat="server">
            <ContentTemplate>
                <asp:Button ID="Button1" runat="server" Text="Button" />
                <asp:Timer ID="Timer1" runat="server" Interval="1000">
                </asp:Timer>
            </ContentTemplate>
        </asp:UpdatePanel>
    </div>
