Page refresh / Postback

When I click a button, I want to change some settings to some objects on my page, refresh so those changes are displayed, and then run some code that takes about 5 minutes to run.

How could I do this?

Also, during my code that takes 5 minutes to run, I would like to be able to change some data in a label and have the label changes be updated on the page while the code keeps running, obviously during this process I do not want the page to refresh or postback.

Thanks in advance.

Anyone have ideas on these questions?

Thanks

Nobody has answered, since very few people go into this area, I'd suppose. The only thing I can think of at this moment is "ASP.NET" multithreading. Do a search on it in google, see if it's helpful.
