Programming Distributed Applications with COM and Visual Basic 6...

Any developer who wants to create LAN-based, WAN-based, and Web-based applications using Microsoft Windows NT Server as a foundation must use many separate pieces of software. Some of these pieces will be supplied by Microsoft, and you or your company will write other pieces. Still other pieces can come from third-party software vendors. Component Object Model (COM) is the glue that ties all of these pieces together. It enables programmers and companies to distribute and reuse their code efficiently. The more you know about COM, the easier it will be for you to put these systems together.
