The Essential Learning Guide for Component-Oriented Application Development for Windows, this book presents an organised, progressive learning path through the jungle of COM details, starting from the beginning and moving to a level of professional practice. It provides necessary (and rarely published) details about COM's essential data structures: BSTR, Variant, and SafeArray. The book emphasizes DCOM security mechanisms, which are rarely covered and absolutely necessary for the use of DCOM in business environments.
You will also find full coverage of ActiveX scripting, a technology that "slips through the cracks" of most COM books. Source code for all projects presented in the book in all four development environments are included on the companion CD-ROM, which also includes trial versions of Microsoft's Visual J++ and Visual Basic; numerous third-party ActiveX components; freeware; and trial-version development environments for HTML and ASP.
