Synchronization is a key feature of many UltraLite applications. This section describes how to add synchronization to your application.
The synchronization logic that keeps UltraLite applications up to date with the consolidated database is not held in the application itself. Synchronization scripts stored in the consolidated database, together with the MobiLink server and the UltraLite runtime library, control how changes are processed when they are uploaded and determines which changes are to be downloaded.
OverviewThe specifics of each synchronization are controlled by a set of synchronization parameters. These parameters are gathered into a structure, which is then supplied as an argument in a function call to synchronize. The outline of the method is the same in each development model.
To add synchronization to your applicationInitialize the structure that holds the synchronization parameters.
Assign the parameter values for your application.
See Network protocol options for UltraLite synchronization streams.
Call the synchronization function, supplying the structure or object as argument.
You must ensure that there are no uncommitted changes when you synchronize.
