Hi Joe,

What you want can't be done by doing some settings in the OAS. I'm developing Oracle web applications since august '99 now, and this is how I solve it. There are two possibilities:
- write a 'wrapper' procedure that creates the wait-screen and afterwards calls the procedure that generates your page that takes so long to load. As you know every procedure that is executed starts a new stream to the client when htp calls are made. Be sure to first do your querying or whatever takes so long, and only after that start with the htp.htmlopen call. Otherwise you'd still get a blank screen.
- Simply use the onLoad attribute of your <BODY>-tag and write some fancy javascript to show a progress bar. You can find a lot of little free javascripts that can do this on the net ( http://www.javascript.com ). The last option is the one I fancy the most, however if you're just beginning with html the first option would be the easiest.

Good luck,

Bastiaan Schaap
