Modules versus Class Method

[T2T2]

I was talking with another vb programmer who suggested something to me.

At the moment I use a common module to set up global variables ( public rather than dim/private)
This is mainly for flag switching, controls such as recordsets, connections, passing on file position info, etc.

It was suggested that using class methods would be more efficient?
Especially in the process of releasing resources.

My guess is that class methods are part of object oriented methodology, and it presents a different way of coding logic?

Has anyone gone down the object oriented approach, or know a bit about class methods?

I am curious to learn some more.
Maybe object oriented programming is more powerful and produces better results? ?
