description: Two things to remedy this: use include instead of import; or put (a reference to) your interface inside a library block.

description: Add a library block for your interface and then importlib() your type library instead. You don't need to import the IDL in this case, but you can if you wish - just move the import line to the begining along with the other imports. Then it might be good idea to have two IDLs for the interface, the first where you define it and you import it in your new IDL, and the second where you import the interface definition only to build a type library from it: import "oaidl.idl"; import "ocidl.idl"; import "itf.idl" [...] library ItfLib { importlib("stdole32.tlb"); importlib("stdole2.tlb"); interface IMyItf; }; -- =============================== Alexander Nickolov, MCSD Panasonic Technologies Inc.

description: When you use import directive to import one IDL file into another, MIDL just puts signle #include statement in the generated header file. That's why you can't see the imported interface. Let's suppose you have files A.IDL and B.IDL and you want to import file B in A. Then the situation will look like this: // A.IDL starts here ... import "B.IDL"; ... // Geenrated A.H starts here ... #include "B.H"; ... So, there is no problem to use interfaces from B.IDL. I'm not sure about importing the file in library section, but if you have problems you can try to move the import "CP.IDL" at the begining of the file.
