Delphi, COM - Including one type library in another type library

I am a Delphi (7.0 Professional) developer. I have developed 2 separate type libraries in 2 separate project groups. I need to use / reference some of the interfaces that are defined in type library B in type library A. Eg. interface ISomething is defined in type library B. Interface IAnother is defined in type library A. Interface IAnother has a method/property that must return a result of type ISomething. How can I do this?

Assuming that you have registered type lib B, then in project A you can:

- bring up the type library viewer
- select the top level node (library)
- go to the uses tab
- right click, show all type libraries
- check the type library for B

then when defining methods / props, you will the see the references from B available as data types.
