To synchronize the current database with the server use the synchronizestatement.

This is exactly the same as choosing Synchronize from the File menu (see Shared Database Synchronization).

Force Synchronization

When Panorama synchronizes with the server, it transfers only the records that have actually changed. These updated records are merged with the existing unchanged records in the local database. A more drastic way to synchronize is called Force Synchronization which transfers the entire database from the server to the local database, including both changed and unchanged records. Here’s how to do this in a procedure:


Theoretically you should never need to do a Force Synchronize, but the option is there if for any reason you think a database is not synchronizing properly. This statement is the same as holding down the Option key when you choose the Synchronize command from the File menu (which converts the menu item to Download Data).

Automatic Pre and Post Synchronization Procedures

You may want to run a procedure automatically before and/or after each synchronization is performed. For example, you may want to make sure that the database is sorted a certain way after each synchronization, or you may want the current record to remain the same after a synchronization. To make this possible, Panorama checks for two special procedures in your database — ..PreSynchronize and ..PostSynchronize. If it finds a ..PreSynchronize procedure it will run it before the synchronization is performed. If it finds a ..PostSynchronize procedure it will run after the synchronization is complete.

When Panorama calls the ..PostSyncrhronize procedure, it passes a dictionary that tells you what happened during the synchronization process. The values in this dictionary are:

Note: Panorama X handles these parameters differently than Panorama 6 did. If you are porting a Panorama 6 with a ..PostSynchronize procedure, you will have to rework any code that accessed these parameters to get information from the dictionary instead of from numbered parameters.


The ..PreSynchronize procedure can be used to save status about the database before the synchronization.

For example, here is a typical ..PreSynchronize procedure that saves the ID of the current record.

letfileglobal BeforeSyncRecordID = info("serverrecordid")

If you also add this ..PostSynchronize procedure to your database, Panorama will use the findid statement to make sure that the current record is the same before and after the synchronization process (unless the current record has been deleted).

findid BeforeSyncRecordID

Note: You could instead use the the find or findbackwards statement to restore the position in the database, like this:

findbackwards BeforeSyncRecordID=info("serverrecordid")

If you also want to display the normal notification when the synchronization is over, here is how to do that in the ..PostSynchronize procedure:

let syncInfo = parameter(1)
let message = getdictionaryvalue(syncInfo,"NOTIFICATION")
let extramessage = getdictionaryvalue(syncInfo,"NOTIFICATIONDETAIL")
nsnotify message,"TEXT",extramessage

You could also customize the message if you wish, or even supply a completely different message.
