Delphi and Delphi ControlsDelphi is an application development environment from Borland. It allows programmers to write application programs for Microsoft Windows very quickly, by "plugging together" pre-written components and adding the minimum of their own coding.
Using pre-written, pre-tested components eliminates much of the tedious, repetitive and error-prone programming tasks normally associated with programming for Windows.
Delphi comes with a large number of these components as part of the delivered product, but one of Delphi's strengths is that components are available from independent developers, performing a huge range of functions. This allows the application programmer to get on with the job of writing the application, without having to write his own text editor, say. He simply chooses a text-editor component that suits his requirements off the shelf from a component supplier.
