Multiple Resource files

I am using Microsoft Visual C++ 6.0. My problem is as so, I have 2 projects which are each basically dialog boxes with lots of buttons. I want to get one to open up the other. My problem with this is that I do not know how to get them to link up so to speak. I created them separately, thus they have separate resource (.rc) files. How do I join the resource files? Or Also each project has its own resource.h file, is there a way I can merge them together?
Am I being specific enough?

--Thank You
