'''Visual Smalltalk Enterprise''' (VSE) is a [[Smalltalk]] dialect that runs only on Microsoft Windows, and is the last in a long line of Smalltalk implementations first produced by Digitalk and now available through Cincom.

Active development has stopped since aroundlate 19991997<ref>{{cite web|last1=Hoyer|first1=Henrik|title=Is Cincom slowly killing Visual Smalltalk Enterprice|url=http://forum.world.st/Is-Cincom-slowly-killing-Visual-Smalltalk-Enterprice-td2513847.html|website=SmallTalk forum|accessdate=2015-12-23}}</ref> and VSE is now only available as a version called VSE 2000, and only to licensed users of previous VSE versions.

==History==

Line 13 ⟶ 30:

* Smalltalk/V Win (1991, [[Windows 3.x]])

* Visual Smalltalk Enterprise (VSE) (1992, [[Windows 3.x]])

* Visual Smalltalk Enterprise 3.0 (1995, [[Windows 95]])

In reality, beforeBefore Smalltalk/V, therethe wasfirst acommercial Smalltalk product, thefrom firstDigitalk one fromwas Digitalk, namedMethods Methodsreleased in 1983. The windowing interface was not graphically based - instead it drew its windows using special symbols stored in a character format. Further, it predated the use of a mouse to drive the interface.

There have also been versions of Smalltalk/V for the Apple Macintosh and IBM OS/2 operating systems. A version for OS/2 was also available for VSE.

In July 1995 ParcPlace and Digitalk merged, later renaming the company to ObjectShare, and in 1997 the company announced it was moving away from Smalltalk and focus towards Java.<ref>{{cite web|last1=Levez|first1=Belinda|title=Reconstructed timeline for Visual Smalltalk from Digitalk|url=http://answers.google.com/answers/threadview/id/236072.html|website=Google Answers|accessdate=2016-03-20}}</ref>

== PARTS Workbench ==

Visual Smalltalk Enterprise usually comes with another sub-system called the PARTS Workbench. This system allows the layout of components, which can then be connected using a visual representation of event-message links. Programmers can add scripts to particular components and build nested-components. They can also enhance the functionality of the main VSE Smalltalk system and use that within the PARTS Workbench.

Although the PARTS Workbench allows very easy development of small systems (somewhat after the style of Visual Basic) it is argued that it encourages fragmentary development. The natural style of using this system tends to lead to lots ofmany links and scripts - it is not based around the idea of 'model' (as used in '[[Model–View–Controller]]' approaches common in many Smalltalks as well as in other languages). However, as an 'HCI' for programmers, the PARTS Workbench has many features that are not in modern Smalltalks. It has an immediacy that makes it very good for introductory teaching and for rapidly implementing programs with visual interfaces.
