C++如何调用CreateWindow函数

CreateWindow函数是在Window.h中吗？MSDN里没写啊。还有CreateWindow函数具体要如何定义，最后4个参数怎么填，哪些是可空的？动态创建窗口是否是CreateWindow然后ShowWindow就可以了？我看的那个CreateWindow函数的实例还是不懂。希望来回答，带一些代码和注释最好了，可以加分。

Answer 1

先调用RegisterClassEx
WNDCLASSEX wcex;

wcex.cbSize = sizeof(WNDCLASSEX);

wcex.style = CS_HREDRAW | CS_VREDRAW;
wcex.lpfnWndProc = WndProc;
wcex.cbClsExtra = 0;
wcex.cbWndExtra = 0;
wcex.hInstance = hInstance;
wcex.hIcon = LoadIcon(hInstance, MAKEINTRESOURCE(IDI_MY111));
wcex.hCursor = LoadCursor(NULL, IDC_ARROW);
wcex.hbrBackground = (HBRUSH)(COLOR_WINDOW+1);
wcex.lpszMenuName = MAKEINTRESOURCE(IDC_MY111);
wcex.lpszClassName = szWindowClass;
wcex.hIconSm = LoadIcon(wcex.hInstance, MAKEINTRESOURCE(IDI_SMALL));

RegisterClassEx(&wcex);

hWnd = CreateWindow(szWindowClass, szTitle, WS_OVERLAPPEDWINDOW,
CW_USEDEFAULT, 0, CW_USEDEFAULT, 0, NULL, NULL, hInstance, NULL);

ShowWindow(hWnd, nCmdShow);
UpdateWindow(hWnd);

接下去还要有消息循环哦~~
