WNDCLASS初始化

Question

下面两段代码有什么区别?
1.

    WNDCLASS    wndclass = {
        CS_HREDRAW,
        WndProc,
        0,
        0,
        hInstance,
        LoadIcon(NULL, IDI_APPLICATION),
        LoadCursor(NULL, IDC_ARROW),
        (HBRUSH)GetStockObject(WHITE_BRUSH),
                NULL,
        szAppName
    };

2.

    WNDCLASS    wndclass = {};

    wndclass.style = CS_HREDRAW;
    wndclass.lpfnWndProc = WndProc;
    wndclass.cbClsExtra = 0;
    wndclass.cbWndExtra = 0;
    wndclass.hInstance = hInstance;
    wndclass.hIcon = LoadIcon(NULL, IDI_APPLICATION);
    wndclass.hCursor = LoadCursor(NULL, IDC_ARROW);
    wndclass.hbrBackground = (HBRUSH)GetStockObject(WHITE_BRUSH);
    wndclass.lpszMenuName = NULL;
    wndclass.lpszClassName = szAppName;

为什么执行1段代码后，进入RegisterClass(&wndclass)会返回假，执行2段代码后，进入RegisterClass(&wndclass)会返回真，

两种写法只是对结构体赋值的不同写法罢了，都是可行的，你说不行，说明第一段成员顺序或者类型没有写对
