Need to capture when the screen has been re-sized?

I need to (perhaps) force a server round-trip whenever the screen has been resized. I have a multiple screens under a tab control. If I manually re-size a screen I can only then get the contents to stretch to full screen if I click on another tab button and then back again.

I would like to detect the screen re-size and then have the screen re-displayed, which I think will happen if I force a server round-trip.

Has anyone done anything like this before.
