Comments
On return, the second parameter contains a pointer to a pointer to a type
description that is referenced by this type description. A type description must
have a reference to each type description that occurs as the type of any of its
variables, function parameters, or function return types. For example, if the
type of a data member is a record type, the typeinfo for that data member
contains the hreftype of a referenced type description. To get a pointer to the type description,
the reference is passed to GetRefTypeInfo.

Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native.
