About this title

Synopsis

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. Whether this be a stock-withdrawal from a warehouse supply system, an invoice-sender or whatever, writing the code in such a way that it can be used by an entire organization to maintain coherent information on the business is worthwhile. Visual Basic 5 classes can be exposed as ActiveX objects. This allows the developer to use DCOM to enable objects to communicate between machines. Also, objects can be both called and scripted by Active Server Pages and controlled by Microsoft Transaction Server, so that they are accessible through a web browser. Tied to these new server-side technologies from Microsoft, we can see that Visual Basic is a great tool to implement such a system. The book does this for a variety of client-server designs, to show how to design and deploy business objects.

About the Author

Rockford Lhotka has over 10 years experience in software development. He worked in Pascal, FORTRAN and Basic on VAX/VMS computers for a number of years until Windows NT and Visual Basic 1.0 first became available. Rockford has worked on many projects in various roles, including software development and design, network administration, help desk management and project management.

With the release of Visual Basic 4.0, Rockford began designing and developing n-tier client/server systems using component-based technology and has been doing so ever since. Rockford has been involved in the design and development of a number of successful, enterprise-level, applications based on the techniques discussed in this book.

In addition to designing and writing software, Rockford is an avid proponent of component-oriented design using Visual Basic and COM. He regularly speaks on these topics, as well as evangelizing the concepts to friends, coworkers and clients.
