OpenBackup - method of the PmgEventViewer object

Open backup.
Empty OpenBackup(Variant vBackup, [Variant nMoveTo])
vBackup(Variant) Backup identifier. The value $latest means the last newest backup.
nMoveTo[optional] (Variant) Parameter indicating where to move the selected row of the opened backup.

The allowed values are: 21, 22, 23 and 24 (default).

See the MoveTo method.

The viewer connects automatically to the last backup after opening. The OpenBackup method allows switching between backups.

The method is asynchronous, therefore the onConnect event is triggered after each connection to the backup (includig the initial automatic connection).

Calling this method is relevant only if the PmaEventGroup object to which this viewr is connected to has the "Storage type" configurator set to the same type that creates the backups, i.e. "Text file (*.ev)" or "dBase III file (*.dbf)".
This method is also functional in Web panels.
