well know,there have some member in the WNDCLASSEX,such as
lpfnWndProc,hIcon,i know "lp" represent to long pointer,"h" represent
to handle.but what does "cb" in cbSize represent to.

iirc bc is bit or byte count :), you should see a dissasembly moving the size for whatch if is a byte or bits count... also i go more for bits count .... in some way.

From MSDN:

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winui/winui/windowsuserinterface/windowing/windowclasses/windowclassreference/windowclassstructures/wndclassex.asp

WNDCLASSEX Structure


typedef struct {
UINT cbSize;
UINT style;
WNDPROC lpfnWndProc;
int cbClsExtra;
int cbWndExtra;
HINSTANCE hInstance;
HICON hIcon;
HCURSOR hCursor;
HBRUSH hbrBackground;
LPCTSTR lpszMenuName;
LPCTSTR lpszClassName;
HICON hIconSm;
} WNDCLASSEX, *PWNDCLASSEX;

UINT = unsigned int = DWORD

I believe 'cb' stands for 'count in bytes'.
