How to use a UpdatePanel to set a labels text to a SqlDataSource value every 5 seconds

I need to use an updatepanel to set a labels text to a sqldatasource value every 5 seconds. I don't really know how to use the updatepanel, I also can't find a way to run a script every 5 seconds.

D开发者_如何学运维oes anybody have any ideas for this?

I'm using vb.net and asp.net.
