In recent years, the concept of "business objects" has taken hold in the developer community. Basically, these are the processes that deal with some input data and mediate the appropriate business response. These pages show how Visual Basic is a great tool to implement such a system. .

Amazon.com Review
Rockford Lhotka's Professional Visual Basic 5.0 Business Objects shows off the capabilities of Visual Basic (VB) 5.0 for developing "business objects" that model real-world entities used in everyday corporations. The author first explores traditional VB "two-tiered" client-server systems, where applications on the client server talk to database servers directly. The author then explores today's three-tiered systems, where business objects--encompassing business rules--work on the server. By separating "business objects" from the user interface code, developers can create more flexible and scalable systems, which is one of the book's main goals.
After modeling a group of objects for a hypothetical video rental store, the author shows how to use these VB classes in a variety of ways, such as in VB 5 forms and even within Microsoft Office (in an Excel spreadsheet). He shows how to deploy the business objects in a traditional two-tiered setting in VB with a database. He then demonstrates how to distribute these objects onto the server (using the Distributed Component Object Model [DCOM] capabilities of VB 5) and, finally, into a three-tiered setting using Microsoft Transaction Server. A final chapter even shows how business objects can be used on the Internet using Active Server Pages (ASPs).
Professional Visual Basic 5.0 Business Objects is a great guide to the new object-oriented capabilities of Visual Basic 5 and other Microsoft products. This text makes a good case for a company to invest in a library of business objects that can be reused across projects and in a variety of architectures. With its outlook on hands-on programming, this book can serve as a capable guide to the future of development in Visual Basic.

This book was the Driving factor in my becoming a MCSD,
By A Customer
This review is from: Professional Visual Basic 5.0 Business Objects (Hardcover)
If your trying to pass the VB desktop/enterprise or Analyzing Requirements MCP exams this is the book for you. If you can read this book, follow the examples, and understand all of the concepts you can pass any of the before mentioned exams. This was my first Wrox press book, I will never buy a computer book from any other publisher again. Feel free to email me for more specific information.

A Seriously Flawed and sloppy work,
By A Customer
This review is from: Professional Visual Basic 5.0 Business Objects (Hardcover)
This book may make for good reading but the Video store project does not work as it is written out here. The flaws in the code are so numerous and frustrating and it really amazes me everyone giving this book such high marks when the project from the book so obviously does not work. Rocky makes use of the LSet statement to copy user-defined-types from one memory location to another with disasterous results. What galls me is that on his web site he defends his dubious methods and from the reviews for the version 6 edition of the book, as evidenced elsehwere here at amazon, he doesn't really make many changes in the new edition. Wrox press books are so promising at a glance but I find the examples are almost always seriously flawed. Beginning Database Programming with VB6 is the same way. You can read the best bits of these books on the MSDN library. Don't waste your money here....

5.0 out of 5 stars
A cornucpia of OO in VB, usual excellence fm WROX and Lhotka,
By A Customer
This review is from: Professional Visual Basic 5.0 Business Objects (Hardcover)
Speaking as a VB programmer, this book is very well written. Lhotka models a hypothetical VideoStore, and takes one step by step, explaining Object Orientation, all the wonderfully simple techniques like For Each Loop implementation for Parent-Child Objects. And after he makes you feel at the top of the world, he brings in DCOM, MTS and ASP ( One feels like VB OO expert, and by then One is!!! ). This book is a must on developers library. I need it everytime, most of the times when I design and sometimes for inspiration.
