using .dll in a Class Library

[Lucrezia]

Hi,
this is my first time in the forum, I hope to be clear.
I have to create a Class Library in VB.NET 2003 (and not other) using a .dll already existed.
I’ve load this .dll in the Reference of my Class Library but I can’t use their objects.
Instead, if I create a Windows Form Apllication, I can load the .dll both in the Reference and in the Form, and in this case I can use their objects.
The question is: Is there in the Class Library a step to do in order to be able to use an existed .dll?
I’ve tried to look on web and I find something about Interface and Interoperability, but without an exhaustive example.
Anyone could help me? Thanks in advance!

Why not I wonder? There's no reason you can't, since you can reference and use it in other project I mean. Perhaps you have problems finding the namespaces? Open the Object Browser and have a look how it's layed out, you can use 'view in Object Browser' context menu option on the reference in Solution Explorer.
