Multiple Projects within a Project????

I'm using VB6 and I have a project that has other projects listed in the Object Explorer. In the primary project (which contains a MDI form), I put a statement in the MDI Form that tries to reference another form from within another project and it won't let me do it. What am I doing wrong?

Thanks,

A group is just a set of projects that go together. If you want to reference another project, then you'd need to shell that project and tell it what to do. After that, you get into remote inputs and the like... stuff beyond my level.

I initially used the "Shell" command, however, what I was trying to accomplish was keeping the called program within the MDI form at all times until the user exited the called program....kinda like calling a form in vbModal. Unfortunately I don't know how to do that...do you?

If it's another program, then you can't nest it within the current form. The best way to do that would be to add what you need to the current project so you can pass everything around quickly and easily.

Yes, I know I can do that but I want to keep the projects separate and not include a form here and there.
