Question

HttpContext not declared

Asked by: fleet

I declare a session varaible in nav.vb file.  When I try and referance it in the Constants.vb page the HttpContext is underlined. The error message says “HttpContext not declared”. Can someone tell me how to fix this?
I'm creating this web application in Visual Studio 2.0.  An example of the code is below:

NAV.VB FILE
Imports Microsoft.VisualBasic
Imports System.IO
Imports System.Data
Imports System.Web.UI

Public Class Nav

        HttpContext.Current.Session("CurrentDir") = "OFAFas"

        If Directory.Exists("o:\current\apps\dgs.otr.fas\FAS") Then
            HttpContext.Current.Session("CurrentDir") = "FAS"
        End If

    End Function

End Class


CONSTANTS.VB FILE
Imports Microsoft.VisualBasic
Imports System.IO
Imports System.Data
Public Class Constants
Public Const TransactionTemplates = "\" &    HttpContext.Current.Session("CurrentDir") & "\TransactionFiles\"  
End Class

Import the System.Web Namespace.

 

by: fleetPosted on 2007-05-09 at 09:14:32ID: 19058187

It didn't work. When I put
Imports System.Web.Namespace
System.Web.Namespace is underlined.  It says doesn't contain any public member or cannot be found.

 

by: ethothsPosted on 2007-05-09 at 09:25:31ID: 19058287

Put precicley this....

Imports System.Web

System.Web is a namespace.  Prehaps I should not have capitalised the word namespace previously.

 

by: fleetPosted on 2007-05-09 at 09:29:47ID: 19058318

I put
Imports System.Web
Still get the same message, HttpContext not declared.  

 

by: ethothsPosted on 2007-05-09 at 10:08:23ID: 19058585

Make sure your project has a reference to System.Web also.

 

by: fleetPosted on 2007-05-09 at 10:25:01ID: 19058715

OK, I made sure my project has a reference to System.Web. It didn't, so I put it in.  Now all of the HttpContext.Current.Session("CurrentDir")  is now underlined and the message is "Constant expression is required".  If I change Imports System.Web to Imports System.Web.IU the HttpContext is underlined and the message is HttpContext not declared.  I'm confused. I know I'm missing something but I don't know what.  

 

by: ethothsPosted on 2007-05-10 at 01:23:58ID: 19063365

You NEED a reference to System.Web. You can optionally inport System.Web or you can just use the fully qualified name System.Web.HttpContext. That is all that is needed.

You sample code is missing the function signature. Please send your real code.
