GAMBAS ALMOST MEANS BASIChttp://gambas.sourceforge.net

A Development Environment Inspired By JAVA™ And Visual Basic™ LINUX JAVA GAMBAS Visual Basic™Abstraction ALMOST Consistency QT MEANS OpenGL BASIC GTK+ SDL Simplification

Gambas History Developed by the French programmer Benoît Minisini First release coming in 1999 Gambas 1.x versions featured an interface made up ➢ Fimilar fashion to the interface of the GIMP ➢ only develop applications using Qt ➢ oriented towards the development of applications for KDE ➢ The last release is Gambas 1.0.19 Gambas 2.x was released on 02 January 2008➢ It featured a major redesign of the interface➢ Gambas 2.x versions can load up and run Gambas 1.x projects➢ use GTK+ for drawing or utilize OpenGL acceleration➢ The Stable Version & Using Now 2.23.1 (27 May 2011) Gambas 3 RC was released on 27 May 2011

WHY NOT USING GAMBAS? Writing Its Own Language Is Funny & Exciting Easy To Learn With Something Visual, Easy & Basic Development Environment Is Easy To Use Fast To Development Something Simple Application/Software An Object-oriented Language Components Are Designed To Be As Simple & Coherent AsPossible You Can Write Software That Is Independent From The Graphical Toolkit & The Underlaying Database Management System Good To Teach At University As Basic Programming Language To Make The Power Of GNU/Linux Libraries Easily Accessible Last, But Not Least : GNU/Linux Is Free, Powerful, Secure & Cool

THE GAMBAS FUTURE✔ New Development Environment✔ QT & QTK+ Components Completed✔ Controls Bound To Data Sources✔ Report Designer✔ DBUS Protocol✔ Making Web Applications✔ Help Porting Visual Basic™ Applications✔ Object Persistence System✔ And Many Moore.. Thank For Your Time To Viewing Facility in Gambas

Thank To...Benoît Minisini , Mark Alexander Bain, Adolf J Winterer, Google, Wikipedia And All...
