window's size

how to get the window’s size (height and width) ?

2

depends on your OS

in windows, you can use a number of functions for determining this:
GetWindowExtEx()
GetClientRect()
etc…

also, during a WM_SIZE message
width = LOWORD(lParam)
height = HIWORD(lParam)

if you are using glut then you can set the initial window size with glutInitWindowSize and then use glutReshapeFunc to set up a reshape handler that will keep track of window reshape events.
