COM Object Communication

[cflanman]

How do you expose the interface of COM ObjectA to COM ObjectB? The GUI wants to "send" business ObjectA to business ObjectB (as in "ObjectB.DoThis(ObjectA)"), so that ObjectB can call ObjectA's services.

Since ObjectA's interface will be derived from IUnKnown, u could as well have the following function in ObjectB
ObjectB::DoThis(IUnknown* pIU)
this way the function DoThis can make calls provided by the interface of ObjectA.
(of course if it is in C++, u have to include
the header of the required interface of ObjectA)

Am i right ?
do reply...
