Hi Randy,

I know that ATL generated MIDL scripts work in this was (this is what has
been bugging me)... I must be doing something wrong. My version of MIDL is
the latest (from the downloadable platform SDK). To illustrate here is a
glimpse at my MIDL file (the names have been changed to protect the
innocent):

        import "objidl.idl";
        import "urlmon.idl";
        import "wtypes.idl";

        /**** Interfaces ********************************************************/
        [ object, uuid(51694020-93AF-11CF-B80D-444553540000),
pointer_default(unique) ]
        interface IInterface1 : IUnknown
        {
                ...
        };

        typedef IInterface1 *PINTERFACE1;

        [ object, uuid(51694021-93AF-11CF-B80D-444553540000),
pointer_default(unique) ]
        interface IInterface2 : IInterface1
        {
                ...
        };

        typedef IInterface2 *PINTERFACE2;

[ uuid(51694100-93AF-11CF-B80D-444553540000), version(1.0) ]
library ILibrary
{
        importlib("stdole32.tlb");

        interface IInterface1;
        interface IInterface2;
};

----------
If I move each of the interface definitions inside of the library statement a
TLB is generated but proxy/stub generation fails. As it is, the proxy/stub
works but it won't generate a type library.
