[VFP6] I have a front-end VFP app that accesses a middle-tier written in VFP. I want the middle tier to be either VCXs or DLLs. How can I abstract this from my front end NewObject() calls?

Example:
Class foo could be in either FooClass.vcx or FooClass.dll
Syntax would be:
NewObject("foo", "FooClass") or
NewObject("FooClass.foo")

The point being, I have to know when coding how my middle-tier is architected.

What I really want is something like:
NewObject("foo", "FooClass")
which would look in either the VCX or DLL as appropriate.

Is there a simple way to do this?
