To create an out-of-process server, just compile your project that has public classes in it into an exe. The exe will contain the logic for the automation object, instead of a dll.

I don't think the website shows how to create either kind, for this, look at the VFP 6 help under out-of-process servers. The site shows how to successfully call them from VFP.
