Application update

A application can fetch an update from an update database. The application needs a licence table additional to the update tables. In the licence table contains the licence number for which updates should be fetched..

An Update Daemon must be initialized before any update can be fetched by the application. The Update Daemon should be initialized at the beginning of the application. For this, the event AfterIntializeMacro of the MiddlePanel are recommended. The system command StartUpdateDaemon can be used for activating the Update Daemon.

The update process can be started with the system command CheckUpdate. If an update was found, a message dialog will be opened which informs about the update process (s. fig. 278 ).
