This 2-part series describes how to create 4D 2004/v11 SQL Plug-in functions that are cross platform, Unicode aware and Universal Binary. Some basic information on how to use the Xcode and Visual Studio IDE (Integrated Development Environment) are also included. Advanced topics such as the use of plug-in areas, event handling and printing are NOT discussed. The main objective is to present the reader with guidance on how to write simple plug-ins that can successfully handle text, picture and numeric data on each of the platforms supported by 4D.

Part 1 of this series herein covers many of these issues in theory. Part 2 will present some specific hands-on examples. (NOTE: ALL SOURCE CODE FILES ARE INCLUDED WITH THE PART 2 DOWNLOAD.)
