Kevin,

I did this a while ago in VC5. I'm guessing that the generated project.h
file has a "include "interface.h" directive, for a file which isn't
accessible to the compiler. From memory...

- put your interface.idl in a "global" include directory (any IDL that
imports it will try and import the interface.h file produced by MIDL.
- add the interface.idl project to any project that needs it
- in the build settings for that file, put in the MIDL build command to
build it

When your project.idl file is compiled, it will import the include.idl (and
generate a "include interface.h" in the generated project.h file). Your
project must be able to find this interaface.h file at compile time.

One bad point about this is that you lose wizard control/usage for the
interface.IDL files - that is you can't use the VC5 wizards to create
methods/properties on the interfaces defined in the non-project.idl - not a
big deal.

Hope that helps,
Scott
