An engineis a section of an application that determines how that application manages and manipulates a type of data. From a developmental standpoint, an engine also can be an application or a module that has an open application programming interface (API) to which your application passes data in order to access the processing capabilities of the engine.
An engine can be another application, such as the Help system for Microsoft Windows CE. Applications pass Help files to the Help system, and the Help system displays those files. An engine also can be part of the operating system (OS), such as the spelling checker. An application passes the spelling-checker text strings, and the spelling checker checks the spelling of the words in those strings.
This section discusses the Help and spelling-checker engines, how they work, and how you can use their capabilities in your applications.
