Bristol Technology Inc, Ridgefield, Connecticut, introduced version 2.1 of its Wind/U Windows-under-Unix environment at the Software Development ’95 show staged in San Francisco last week. Version 2.1 of the product supports Microsoft Corp’s Foundation Classes 3.0 for features such as docking toolbars and property sheets; Silicon Graphics Inc’s Irix V workstations and Visual C++ 2.0. The Windows source code house is still promising its Unix implementation of OLE 2.0 by summertime and had an early version up and running at the software event with sample application code such as Microsoft ‘drawcli’ and an in-process server Dynamic Data Library showing in-place activation, compound files and compound object model functionality. Bristol’s next challenge is to find Windows applications houses that want to put their programs up under Unix. It has a handful already lined up it claims.
