In real development, project groups will usually be used with some form of
components. When you are creating a system that uses one or more components, especially
components that are still in development, a project group can greatly simplify
your work. After a component is stable, or when using third-party components,
there should be no need to have their code available and a simple reference to
the component should suffice. To illustrate the use of project groups when developing
with components, this section walks you through the creation and debugging of
an ActiveX DLL.

NOTE - To Which Project Am I Adding? Other than
the previously mentioned options, the Project Explorer behaves the same when dealing
with a project group as it does for a single project. The project affected by
the various Add commands, such as for forms and modules, is always the currently
selected one.
