Hi!

I have no experience in COM interop so I really need some help.

I have to reuse some vb.net code in VBA.
I made a new class library project where I added a new com class with
some public members and methods. After resolving some conflicts, like
some Warnings about generic types, I was able to add this library in
VBA in References.

my questions are:

do I have to add all my classes from vb.net as Com classes in this
library? Can I still let some as normal classes? Am I able to use them
like this?
what about masks? Am I able to add them also and reuse in VBA?

I have to pay attention to all used types not to be generic ones? where
can I find which types are nongeneric?

thanks a lot!
