How to call IDL 'modules' from C++?

IDL has a way of specifying a 'module' which has a name and a list of functions. These functions become known to the user
via the typelibrary. As the module is not a interface, how do we call these functions in VC++?.
In VB, I noticed that, if you just include the dll or olb as reference, you can start using those functions directly, as if they are
available as 'global' functions. However, when I tried to use that olb or dll in VC++ using #import, the generared .tli/tlh files
don't contain any info about these functions. Class Wizard also gave the same result.
One example of that type of OLB: C:\Program Files\Common Files\Microsoft Shared\Vba\Vba332.dll
Can any one please help me out to get those functions for use in VC++?
