C++ Database Applications with the Paradox Engine

Overview

C++ Database Applications with the Paradox Engine gives you the tools you need to write professional-quality Paradox business applications. After introducing you to the Paradox Engine, its advantages, and latest developments, this book offers solutions and complete code for three crucial database functions missing from the Engine itself: maintaining relational integrity, validity checking, and queries. Through the sample business application presented here, you'll learn how to plan an object-oriented application; create a user interface complete with drop-down and pop-up menus, scrolling list boxes, data field boxes, buttons, and more; integrate the Paradox Engine and the user interlace by creating C++ classes for functions the Engine cannot perform; develop C++ classes that maintain the relational integrity of a record in a multi-user environment; and create C++ classes that do queries.
