(from what you've shown) In line 167 you create a reference to an object of
type Object, but not an actual object. Thus, rs is an empty (null)
reference. In line 168, you attempt to use the null reference to qualify use
of the EOF, which fails because rs does not point to an object.

What is rs supposed to be? I could make a guess that you are trying to
create a recordset and that you are using ADO in your ASP application? The
..NET data access technology is ADO.NET, which does not use recordsets. When
you write:

Dim rs As Object

in VB.NET, you are creating a reference to an object of type Object (Object
being the class that sits at the top of the .NET Framework class hierarchy).
I could simply say that to create an actual object, you would just change
the statement to:

Dim rs as New Object

Then, rs would contain the address of the of the instance. However, that
answer masks the differences between the languages and between ASP and
ASP.NET, and will probably only get you to the "next error".
In VB.NET, as opposed to "classic" VB/VBA, you are dealing with a new,
object oriented programming language with rules that are quite different
from those for VB/VBA.

To convert your current ASP applications properly, you'll need to understand
the new world of .NET and how it differs from older technologies.
