Hi-

I'm trying to simply set/get session variables with no luck.

I'm attempting to set them in global.asax:
Sub Session_Start(Sender As Object, E As EventArgs)
Session("UserName") = "gagz"
End Sub

and trying to access from an aspx file a couple ways:
in aspx as:
<title>Welcome <%=Session(&quot;UserName&quot;)%>

and in aspx.vb file:
txtbox.Text = Session(&quot;UserName&quot;)

Neither way is working... am I missing something obvious?

Thanks for the help.

I don't think you can set a session variable within the global asax file...

try setting it a different way... i alwas use a splash screen (a welcome screen you can say) and when the people hit ok, then in the code behind that ok button set your session...

just an idea.

well thats stinks... I want it to be someplace generic, because some of the values will be coming from a cookie. Also, the user could enter from any page on the site... There my be a generic place to do it...

Could I maybe do it in a header file and do a simple check to see if a session is started when each page loads?

This worked for me. ASP.NET does not like render tags. Instead use response.write(). Make sure you use the parentheses. I don't know why your codebehind wasn't working, since I didn't see all the code.

global.asax
------------------------
<script language=&quot;VB&quot; runat=&quot;server&quot;>
Sub Session_Start(ByVal Sender As Object, ByVal E As EventArgs)
Session(&quot;UserName&quot;)=&quot;ASDF&quot;
End Sub
</script>

test.aspx
---------------------------
<%@ Page Language=&quot;VB&quot; %>
<html>
<body>
<%
response.write(Session(&quot;UserName&quot;))
%>
</body>
</html>

you're right... response.write does work... but I still can't assign the variable to a text box in my code behind:
txtName.Text = Session(&quot;UserName&quot;)

any ideas?

Just wondering if anyone ever had a chance to see if they could read the session variable in code behind and assign it to a text box as above?

I use the session feature with a custom session object that holds all the user permissions, including user name. Once I access the custom object I could place the data anywhere I want to, even in textboxes. works great for me.

this saves a session object; it is run when user logs in:
Dim authRes As Boolean = authObj.authenticate(txtUser.Text, txtPass.Text)
If (authRes) Then
'set session object
Session(&quot;curSessionRights&quot;) = authObj.session_obj

this accesses the session object; is in page_init:
cur_session.session_obj = Session(&quot;curSessionRights&quot;)
