My thanks to Scott Button for a pointer to the fix for this. Just in case
anyone here comes across the problem, here's the pointer.

It seems that when making a reference to anything inside Project, from VBA
code external to Project, the reference needs to be "fully qualified."

So, in my own code below,

Dim objMSProject As MSProject.Application
Set objMSProject = New MSProject.Application
...
Set R = ActiveProject.Resources
should read
Set R = objMSProject.Resources

and
Names = Left$(Names, Len(Names) - Len(ListSeparator & " "))
should read
Names = Left$(Names, Len(Names) - Len(objMSProject.ListSeparator
& " "))

Go figure.

Well, I'm stumped again and in need of serious assistance.

I'm building an Excel add-in for creating project plans, which then are
exported to MS-Project for tracking. But I need to have the resource list
in an Excel worksheet before the plan can be built. And that's where I'm
in trouble. The rest of the add-in actually works, including the piece
that exports the plan to MS-Project (2003). But I'm stuck on the part
that automates the retrieval of the resource list from Project.

The code below shows how far I've been able to get on my own. It actually
works, every second time that it runs, and it fails every second time that
it runs. I get a message that the application server doesn't exist or is
not available. But I can't figure out what's going on, and the available
documentation is, well, excessively challenging for me (read that as I
don't know Project's object model and I can't find readable
documentation). Can somebody here straighten me out? I would be entirely
grateful

Tony
