Cincom® VisualWorks® 9.0

Cincom VisualWorksIt is our pleasure to bring you the current major release of Cincom VisualWorks 9.0. Both Cincom® ObjectStudio® and Cincom VisualWorks share the same core libraries and foundation, which means enhancements on the foundation improve both products. This release has very significant and meaningful upgrades for the Cincom Smalltalk Foundation and for each product.

VisualWorks is an enterprise-class, multilingual, cross-platform, application development and delivery platform that’s used by worldclass companies in areas such as semiconductor manufacturing, shipping, financial risk management, insurance, banking, government, education and healthcare.

The VisualWorks suite is the premiere Smalltalk environment and has an unrivaled live and interactive development environment that is highly effective and productive.

VisualWorks includes components for any type of work that your team might contemplate—Client, Server, Client-Server, Distributed, Grid or Web—and allows you to build them with superior development tools.

VisualWorks can work or integrate with most standard technologies such as internet protocols (HTTP, HTTP/2, FTP, POP3, etc.), secure protocols (TLS, HTTPS), most relational databases (RDBs), sockets, COM, Web services (WS*), Web standards (HTML5, JavaScript, Ajax, JSON, WebSockets), MQSeries and more. This allows VisualWorks to seamlessly plug into an enterprise infrastructure—an important feature for IS shops that need to integrate multiple applications from multiple sources.

VisualWorks Project Manager

The Project Manager allows easy location and launching of projects as well as new project creation.

GUI Tools

The Cairo graphics package is an option with available libraries, allowing powerful graphic techniques for attractive applications. The user interface operates with multiple processes instead of a single “distinguished” process, enabling more responsive applications. Shortcut keys are industry standard where applicable.
