About the Author

SBJ

United States United States
Real name is Steve Johnson. Programming since 1979. Started on a Heathkit Micro with a DEC LSI-11 and UCSD Pascal. Moved to PCs & DOS as soon as Turbo Pascal became available. Did some Assembly, ISR, TSR etc. All this while working for a Manufacturing Co. for 8 years. Had my own solo Co. doing barcode labeling software for 4 years (terrible business man, all I wanted to do was code). Since then working for various software companies. Moved to Windows around the time of 3.1 with Borland C then C++. Then on to VC++ and MFC, and just about anything I could get my hands on or had to learn for my job, and been at it ever since. Of course recently I've been playing with .NET, ASP, C#, WPF etc.
