Hi,
No, I've only tried it with exchange rates at the moment and I don't really use it as a continuous feed. I have the processing linked to a button at the moment.
It was just a means of proving to a customer that it could be done on demand - one less thing to worry about
The way it seems to work is that a request is made to the URL and the results are returned in XML and you parse them.
I'm sure a timed processes could be set up to periodically issue a request to a news feed and display the results on a window? There a quite a few XML commands to help you parse XML files.
