Automatically Synchronize With Central every hour

I don’t know why Erik wants to call this FaceMelter, but here is an example of how to use the Idling event and 2014’s new SynchronizeWithCentral method to automatically Synchronize With Central at a desired interval.

For testing purposes I set it to auto-synch every 3 minutes. You would probably want an interval a bit longer 🙂

public static class myCommand
{
    // store the time when the last save occurred
    static DateTime lastSaveTime;

    public static void idleUpdate(object sender, IdlingEventArgs e)
    {
        // set an initial value for the last saved time
        if (lastSaveTime == DateTime.MinValue)
            lastSaveTime = DateTime.Now;

        // check the current time
        DateTime now = DateTime.Now;

        TimeSpan elapsedTime = now.Subtract(lastSaveTime);
        double minutes = elapsedTime.Minutes;

        UIApplication uiApp = sender as UIApplication;
        // write a comment to the journal file for diagnostic purposes
        uiApp.Application.WriteJournalComment("Idle check. Elapsed time = " + minutes,true);

        // don't do anything if less than 3 minutes since last auto-save
        if (minutes < 3)
            return;

        Document doc = uiApp.ActiveUIDocument.Document;
        if (!doc.IsWorkshared)
            return;

        TransactWithCentralOptions transact = new TransactWithCentralOptions();
        SynchronizeWithCentralOptions synch = new SynchronizeWithCentralOptions();
        synch.Comment = "Autosaved by the API at " + DateTime.Now;
        RelinquishOptions relinquishOptions = new RelinquishOptions(true);
        relinquishOptions.CheckedOutElements = true;
        synch.SetRelinquishOptions(relinquishOptions);

        uiApp.Application.WriteJournalComment("AutoSave To Central", true);
        doc.SynchronizeWithCentral(transact, synch);

        // update the last saved time
        lastSaveTime = DateTime.Now;
    }
}

class rtcApplication : IExternalApplication
{
    public static FailureDefinitionId failureDefinitionId = new FailureDefinitionId(new Guid("E7BC1F65-781D-48E8-AF37-1136B62913F5"));
    public Autodesk.Revit.UI.Result OnStartup(UIControlledApplication application)
    {
        // register the idling event when Revit starts
        application.Idling += new EventHandler<IdlingEventArgs>(myCommand.idleUpdate);
        return Result.Succeeded;
    }
    public Result OnShutdown(UIControlledApplication application)
    { return Result.Succeeded; }
}
