Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Visual Objects is an object-oriented computer programming language that is used to create software programs that operate primarily under Windows. Although it can be used as a general-purpose programming tool, it is almost exclusively used to create database programs. The original Visual Objects project (code-named Aspen) was started as part of Nantucket's attempts to bring the Clipper language to Windows, and move from the procedural to the object-oriented style. It also converted Clipper from a p-code system to being a true native compiler and introduced more elements of the C language (such as typed variables), while including Windows extensions (such as COM, ODBC, and later ADO). With its symbol datatype, it offers the ability form name-based linkages, which may be used to connect menu events to object methods or form direct linkages between server columns and controls.
