The Session doesn't work?

wangweiming · July 27th, 2005, 05:20 AM

Hi,friends,I'm a beginner.
I use the session to store a variable,then I change it,but it doesn't alter ,it seems that the variable isn't stored in the session.

the code as follow
<%@ Page language="c#"%>
<script Language="c#" runat="server">
void EmptyClick(object sender, EventArgs e){
    Session["BasketCount"] = 0;
}
void AddClick(object sender, EventArgs e){
    if(Session["BasketCount"] != null){
     int i = (int)Session["BasketCount"];
     i++;
     Session["BasketCount"] = (object)i;
    }
    else {
     Session["BasketCount"] = 1;
    }
}
</script>
<html>
<body>
    <form id="BasketForm" method="post" runat="server">
     <asp:Button id="Empty" OnClick="EmptyClick" runat="server" Text="Empty"/>
     <br />
     <asp:Button id="Add" OnClick="AddClick" runat="server" Text="Add"/>
     <br />
     Basket items : <%=Session["BasketCount"]%>
     <br />
    </form>
</body>
</html>

When I push the "add" button,the Basket item(Session["BasketCount"]) doesn't increase as expected.

THANKS!

The code you posted worked fine at my computer as it is, perhaps it is a cookie problem or such.

BTW... I made the code a bit less verbose, and probably a bit less readable... ;)

Code:

  void AddClick(object sender, EventArgs e)
  {
      Session["BasketCount"] = 
          ((Session["BasketCount"] != null)? 
              (int)Session["BasketCount"] : 0) + 1;
  }

Hope it helps, Jacob.

Thanks for your help,Jacob.
It's so odd that the Session["basketcount"] dosen't changed in my computer,even the cookie has open completely.Maybe something in my iis goes wrong .

I have find the sticking point.It was brought about by Zone Labs security software.When I closed it,the problem went all right.
Thank you all the same,jacob.

I find the sticking point all by chance.Hope this topic can help some unlucky beginners like me.(It has puzzled me for nearly one weak!)

Well, don't you think that it was a cookie problem after all then? I have used Zone Alarm as well, and have had similar problems.

Maybe.But when I opened Zone Alarm,I can used the cookie in my programme freely.I setted Zone Alarm by default.

For tomorrow I work hard!
