WNDCLASSEX wc :This is a struct that contains the information for the window class.

ZeroMemory(&wc, sizeof(WNDCLASSEX)) : ZeroMemory is a function that initializes an entire block of memory to NULL.

wc.cbSize = sizeof(WNDCLASSEX): size up this structure and tell it what it's measurements are.

wc.style = CS_HREDRAW | CS_VREDRAW:There are plenty of values we can insert, but we will almost never use any of them in game programming.

wc.lpfnWndProc = WindowProc:This value tells the window class what function to use when it gets a message from Windows.

wc.hInstance = hInstance:Just put the value Windows handed to us in WinMain().

wc.hCursor = LoadCursor(NULL, IDC_ARROW):This member stores the default mouse image for the window class.

Window Size Versue Client Size

BOOL AdjustWindowRect(LPRECT lpRect,DWORD dwStyle,BOOL bMenu);
RECT wr = {0,0,windowWidth,windowHeight};
LPRECT lpRect: Send &wr.
WORD dwStyle: your windowstyle.
BOOL bMenu: not necessary always FALSE.

part of Code


RECT wr = {0,0,500,400};
AdjustWindowRect(&wr,WS_OVERLAPPEDWINDOW,FALSE);
hWnd = CreateWindowEx(NULL,"WindowClass1","WindowClass1",WS_OVERLAPPEDWINDOW,300,300,wr.right-wr.left,wr.bottom-wr.top,NULL,NULL,hInstance,NULL);


It is adjust your image at right  position while you change your window size.
