A TLB file is a "type library". It is a compiled version of the IDL for
a set of COM interfaces. IDL is modified subset of C++ that is used to
declare the functions within a COM interface, their parameters, and
their types. It is intended to be a language-independent way to define
the functions within an interface.
Looks like you're on your way.
