Window messages.. Quite easy, apart from one: WM_SIZE.
How is the lParam supposed to specify both the width and the height of a window's client area? (I've probably missed something)

lParam
The low-order word of lParam specifies the new width of the client area.
The high-order word of lParam specifies the new height of the client area.
So,
width = lParam & 0xffff;
height = (lParam >> 16) & 0xffff; // or you can use lParam >>> 16;
lParam is dword (double word), of length of 4-byte. A word, in x86 terms, is 2-byte. And little-endian.
