AJ Suite of Components, Gabriel Inzirillo

AJAR SA is the Swiss 4D Distributor. It has more than 25 years experience in distributing 4D Solutions to the Swiss and Liechtenstein markets.  AJAR’s expertise in 4D is far more than simply distributing the 4D Solution.  AJAR SA offers many services such as first level support, consulting, training, and audits.  All of that combined with a tight relation with 4D SAS gives their partners the best service possible.

Since a long time ago, AJAR SA have proposed some components to the 4D developers (ToolTip, Regex, etc.), but those components were never harmonized and some were even never released.  In that matter, AJAR is now bringing forth some tools that can help 4D developers to build applications with some nice UI features as well as some well-designed tools to help solve some daily business issues.
