the window receives a WM_SIZE message
wParam carries additional information
http://msdn.microsoft.com/en-us/library/windows/desktop/ms632646%28v=vs.85%29.aspx

you can also use WM_ACTIVATE
http://msdn.microsoft.com/en-us/library/windows/desktop/ms646274%28v=vs.85%29.aspx

but, WM_SIZE carries more info - the window is sent both messages, along with a few others
