求助，win32程序不显示窗口

Question

求助大神，为什么这段代码运行不显示窗口，但是任务管理器里面显示这个程序正在运行？

#include<windows.h>

#define WINDOW_WIDTH 800
#define WINDOW_HEIGHT 600
#define WINDOW_TITLE TEXT("我的游戏程序")
#define CLASS_NAME TEXT("CLASS_NAME")

LRESULT CALLBACK WndProc(HWND hwnd,UINT msg,WPARAM wParam,LPARAM lParam);
int WINAPI WinMain(HINSTANCE hInstance,HINSTANCE hPrevInstance,LPSTR lpCmdLine,int iCmdShow)
{
    WNDCLASSEX wndclass = {0};
    wndclass.cbSize = sizeof(WNDCLASSEX);
    wndclass.style = CS_HREDRAW | 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 = TEXT("CLASSNAME");

    if (!RegisterClassEx(&wndclass))
    {
        return -1;
    }
    HWND hwnd = CreateWindow(CLASS_NAME, WINDOW_TITLE, WS_OVERLAPPEDWINDOW,
        CW_USEDEFAULT, CW_USEDEFAULT,CW_USEDEFAULT,CW_USEDEFAULT,NULL,NULL,hInstance,NULL);

    //MoveWindow(hwnd,250,80,WINDOW_WIDTH,WINDOW_HEIGHT,1);
    ShowWindow(hwnd,iCmdShow);
    UpdateWindow(hwnd);

    MSG msg = {0};
    /*while (msg.message != WM_QUIT)
    {
        if (PeekMessage(&msg, 0, 0, 0, PM_REMOVE))
        {
            TranslateMessage(&msg);
            DispatchMessage(&msg);
        }
    }*/
    while (GetMessage(&msg, NULL, 0, 0))
    {
        TranslateMessage(&msg);
        DispatchMessage(&msg);
    }
    UnregisterClass(CLASS_NAME,wndclass.hInstance);
    return 0;
}
LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
    switch (msg)
    {
    case WM_DESTROY:
        PostQuitMessage(0); break;
    default:return DefWindowProc(hwnd,msg,wParam,lParam);
    }
    return DefWindowProc(hwnd, msg, wParam, lParam);
}

用vc++新建一个win32窗口程序，和你的对照下。
