I don't understand how I would do this using the DLL approach. I presume that each time I call the dll, it will always return properties the first object - I don't know how I would return the full range of objects. Is there some way to impliment a NEXT UNTIL or something, or some other way of returning properties of a series of objects?

Create a collection in the VB .DLL to hold the data, and populate it with the data that you want to return; rather than returning the value as a single value from the method, simply spin through the collection after calling the method that populates it.
