I keep getting an error that says...

Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive

...when I try to use the Session object. I have Session State enabled in both IIS and in my web.config file.

The only thing I can think of is that maybe the fact that there are some classic ASP pages in the same folder as my ASP.NET web application, maybe that's throwing IIS off. I'm not passing any info from the classic ASP page to the ASP.NET page (that's being done with good old cookie). The error is being thrown between one aspx page and another.

Any ideas?

I figured this out guys.

You can't declare members like...
 
.NET hates that. You have to declare the member like this...
 
And then later on set it equal to your session variable, e.g.
 

Seems kind of stupid to me, but oh well.

You can define it as Dim myVariable As String = <something>. Are you sure that the Session("myVariable") is not nothing. That may be the problem. Also, you can disable session state in the @Page directive, make sure that isn't a factor also.

Hi Brian,

I get that you can declare members/variables as

Dim myVariable As String = <something>

It's just that .NET doesn't want to do that when the <something> is a value from the session class.

Try it out. Let me know if it works for you.

Aaron

Yeah, I do a IsNothing(Session("object")) first to make sure it exists, because then you get an error for that when you convert it.

Dim var as string
If (IsNothing(Session("variable"))) then
  var = Session("variable").ToString()
else
  var = string.emtpy
end if
