This is a really simple issue, but I have racked my brain on how to get these values over. I am knowledgable on asp classic but .net has me lost. All of the code I am using, or trying to use, is vb. In classic asp I could easily set a variable and say that <%test_value = 1%> then call it later by saying <%response.write test_value%>.

I basically am trying to learn how to do this simple task in VB but I am feeling stupid on why I cannot make it happen. I am trying to do the same thing but in the .vb file, and pull the value into the .aspx file.

Below is a very simple string that I want to work, which does not. I think I am attaching myself to classic and making it more difficult than it is in .net. Thanks for your help!
---.vb file---

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Dim test_value = "25"
    End Sub
 
End Class

On first glance I would say you haven't declared your variable properly in the code file:

Dim test_value = "25"

becomes

Dim test_value as String = "25"

Apologies, I should have looked more thoroughly.

I would have Response.Write(test_value) in the code behind i.e.

---.vb file---
Partial Class _Default
    Inherits System.Web.UI.Page
 
    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Dim test_value As Integer = 25
        Response.Write(test_value)
    End Sub
 
End Class


And remove <% %> from the aspx file.

Take a look here for some help to get you up to speed http://www.asp.net/learn
