Hi all,

I am still unable get retrieve an Application variable in .NET.

I can use the Session object by just typing.. Session("myVar") in aspx or
..vb.
However, using Application("myVar") results in nothing.

I have tried executing the following code..but nothing is outputted.

If Application("UrlPrefix") Is Nothing Then
Response.Write("<NULL>")
Else
Response.Write("Type: " & Application("UrlPrefix").GetType().Name & ",
Value: """ + Application("UrlPrefix").ToString() + """")
End If

If i include this code.. 'Response.Write(Application.Keys.Count) i get 0

So either the application object is not being created ..or it needs to be
referenced some how..

Am i missing something here?

The code is contained in a .vb file used for a user control.

These are the imports i am using, in case they are relevant.
Imports Microsoft.VisualBasic
Imports System
Imports System.Configuration
Imports System.Data
Imports System.Data.SqlClient
Imports System.Web.UI
Imports System.Web.UI.WebControls

Would appreciate any help to get beyond this.!!!

Cheers,
Adam
 
You mean that even code like this will not run as expected?

Application("mykey") = "value";
Response.Write( Application("mykey") );

I think you should check the exactly excute path during the request.
The application variables may not been initilized correctly.

Click to expand...

You cannot initialize Application variables in code.
They can only be initialized in global.asax.

You can *assign a value* to an Application variable in code,
but you cannot create an Application variable in code.

Is that what you've been trying to do ?
Or, are you attempting to assign a value to an already-created App var ?

What happens if you run :

Dim AppVarCount As String = Application.Contents.Count.ToString()
Response.Write(AppVarCount)

?
