Front End Refresh on different machines or networks.

Front End Refresh on different machines or networks.

I am working on an application that has been split into a front end and a back end. The front end can run on different machines, and even on different networks. I can make changes to the underlying back end records and do a requery, but I need to have any changes show up instantly for anyone else using the system. Refresh only updates the image for the instance on one computer. How do I get it to happen for everybody at the same time?

RE: Front End Refresh on different machines or networks.

You could use the timeout event on the form to perform a refresh every XYZ(seconds, minutes, hours) etc.

Or you could poll another DB record to see when the last time something changed and if so do a refresh.

None of these approaches are very efficient, what are all the current users looking at that needs real-time updates to be so critical, is a live chat application?
