OK, I think I found that I can use a TOmniMessageQueue as one option. If I create this with a handler for the OnMessage event, that seems to allow me to accomplish updating the Activity Indicator in the UI without adding much overhead to the Parallel.Pipeline process. Is this a good option for the library or is there another method that perhaps works better?

I am just getting familiar with using OmniThread and I have been trying to figure out how to get feedback from a Parallel.Pipeline to the main UI thread to update an activity indicator or progress bar. I understand how to use TOmniEventMonitor when using the CreateTask API call. But as I look at a Parallel.Pipeline command I can't see how to register a TOmniEventMonitor object to collect info from the threads that are part of the Pipeline. What is the best option to get messages back to the UI to update progress for a Parallel.Pipeline task? In looking at the FileScanner demo, the are doing something like this to create the task. FFolderScanner := Parallel.Pipeline .NoThrottling .Stage(UniqueFilter_asy) .Stage(FolderScanner_asy) .NumTasks(inpNumScanners.Value) .Stage(DataCollector_asy, Parallel.TaskConfig.OnTerminated(WorkDone) ) .Run; How do I link in or use a TOmniEventMonitor that can work with each of the Stages of this Pipeline. Thanks. tim
