entrypointnotfound error although a DLL is referenced

I'm working in Visual Basic.net and I'm new to creating DLLs. I ran
into a problem creating a simple DLL. I used this newsgroup to try and
figure out what was wrong and I'm still stuck with an
entrypointnotfound error. What do I need to do to make this simple
subroutine call work?

This is the code for the DLL:
<CODE>
Public Class returnNumber
Public Sub Encode_L10()
MsgBox("Returns a 10")
End Sub
End Class
</CODE>

This is the code for the calling form:
<CODE>
Public Class Form1
Inherits System.Windows.Forms.Form
'Windows Form designer code snipped
Public Declare Sub Encode_L10 Lib "ForrestryDLL.dll" ()

Private Sub frmMain_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load

Encode_L10()

End Sub

End Class
</CODE>

The DLL "ForrestryDLL.dll" is listed under "references" in the solution
explorer. What am I doing wrong?

VB.NET cannot be used to create applications which export functions that can
be used with 'Declare'.
This is the code for the DLL:
<CODE>
Public Class returnNumber
Public Sub Encode_L10()
MsgBox("Returns a 10")
End Sub
End Class
</CODE>

Use this code to call the function:

\\\
Imports ClassLibrary1
..
..
..
Dim r As New ReturnNumber()
r.Encode_L10()
///
