BackupDatabaseDlg::userNotify Method

The following example of a notification callback shows the handling of the JadeDatabaseAdmin class FileBackupStartEvent, BackupAbortedEvent, BackupCompleteEvent, and backup progress events.

userNotify(eventType: Integer; theObject: Object; eventTag: Integer;
           info: Any) updating;
begin
    if eventTag = BackupComplete then
        finalise(false /*completed ok*/);
        return;
    endif;
    if eventTag = BackupAbort or eventTag = BackupCancel then
        finalise(true /*aborted*/);
        return;
    endif;
    if backupCancelled then
        // The user has cancelled the backup, avoid processing any of
        // the events handled below
        return;
    endif;
    if eventTag = FileBackupStart then
        currentFile := info.DbFile;
        if currentFile <> null then
            beginNotification(currentFile, DbFile.BackupProgressEvent,
                              Response_Continuous, BackupProgress);
            updateProgress("Processing file...", currentFile.name, 0);
        endif;
    elseif eventTag = FileBackupComplete then
        if currentFile <> null then
            endNotification(currentFile, DbFile.BackupProgressEvent);
        endif;
        currentFile := null;
    elseif eventTag = BackupProgress then
        if currentFile <> null then
            updateProgress("Processing File...", currentFile.name,
                           info.Integer);
        endif;
    endif;
end;
