I was curious if anyone could be of help.

I am currently taking a class (Programming with VB.NET) and the instructor has gone off on his own path, naturally away from the book, and gotten into an area that I admittedly am having a real hard time with and have not been able to get much help from the instructor.

We are creating and working with .dll files. Creating them, then referencing them to create new programs.

I have gone through the entire book and there is no information about working with .dll's, I have searched extensively on the internet looking for help and even gone through most of the MSDN library trying to get a better understanding.

Does anyone have any links or information on setting up and using .dll's in the VB.NET programming language?
