Presenting the definitive guide to building object-oriented software for the Internet and client/server applications. Some 125,000 software developers are already using the Powersoft Foundation Class (PFC), and this book/CD-ROM explains the PFC Library for PowerBuilder-the collection of programs frequently used and reused by developers when building software applications with PowerBuilder. Encompassing the latest 5.1 release of PowerBuilder, this sourcebook provides in-depth guidance on application development, performance tuning, maintenance, documentation, and more. A special section covers the use of PFC on the Internet. Given that Powersoft itself asked these expert authors to create this package, it promises to be the premier PFC Library resource!
