>Isn't there a way to access the initial instance (CREATEOBJECT ...)

CREATEOBJECT would be used to start up a new instance, not connect to one already running.

I don't know of a way to directly call into instance1 from instance2. You can easily send a message from instance2 by using a go-between such as a log dbf or MSMQ event queue. Your problem is how to receive and act on that message inside of instance1. Thus the need for a timer or VFPCOM binding to MSMQ events.

More ideas, anyone?
