请问一下哪位大神帮我看看程序，怎么运行结果是窗体创建过程失败，按照书上敲的代码，求解，谢谢。

Question

#include

LRESULT CALLBACK WinProc(HWND hWnd, UINT msg, WPARAM wParam, LPARAM lParam);

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInst, LPSTR lpCmdLine, int nShowCmd)
{
WNDCLASSEX wClass;
ZeroMemory(&wClass, sizeof(WNDCLASSEX));
wClass.cbClsExtra = NULL;

wClass.hInstance = hInstance;
wClass.lpfnWndProc = (WNDPROC)WinProc;
wClass.lpszClassName = "Windows Class";
wClass.lpszMenuName = NULL;
wClass.style = CS_HREDRAW | CS_VREDRAW;

if (!RegisterClassEx(&wClass))
{
    int nResult = GetLastError();
    MessageBox(NULL,
        "对不起，窗体注册失败",
        "窗体类错误",
        MB_ICONERROR);
}


HWND hWnd = CreateWindowEx(NULL,
    "Window class",
    "这是一个简单的窗体程序",
    WS_OVERLAPPEDWINDOW,
    200,
    200,
    640,
    480,
    NULL,
    NULL,
    hInstance,
    NULL);

if (!hWnd)
{
    int nResult = GetLastError();
    MessageBox(NULL,
        "创建窗体过程发生错误",
    "窗体创建失败",
        MB_ICONERROR);
}

ShowWindow(hWnd, nShowCmd);

MSG msg;
ZeroMemory(&msg, sizeof(MSG));

while (GetMessage(&msg, NULL, 0, 0))
{
    TranslateMessage(&msg);
    DispatchMessage(&msg);

}
return 0;

}

LRESULT CALLBACK WinProc(HWND hWnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
switch (msg)
{
case WM_DESTROY:
{
PostQuitMessage(0);
return 0;

}

    break;

}

return DefWindowProc(hWnd, msg, wParam, lParam);

}

如果是vc++，用新建项目-win32应用，创建一个初始化的代码，自己对照，不要找着抄，这么抄很容易写错。
