I've seen plenty of examples of VFP developed COM components which simply return a value. That's straightforward. But how can I accomplish the following example?

My VFP app calls an out of process COM component (developed in VFP6) which SCANs through a large table and does a bunch of processing. This will be time consuming, so I want to display a thermometer bar on the UI to show its progress for the end user. The COM component is out of process and I know that it cannot display any UI, so what's the best way to make the calling process provide a thermometer bar?

Thanks in advance,
