Answer 1

nCmdShow值是否正确，是否隐藏了

Answer 2

我用SW_SHOWNORMAL也无法显示，找来找去没找出问题在哪儿

Answer 3

 wndclass.lpszClassName="Action!";
    if (!RegisterClass(&wndclass))
    {
        MessageBox(NULL,"error in register!","",0x10);
        return 0;
    }
    hwnd=CreateWindow(TEXT("Do it!"),
        TEXT("Ðж¯"),WS_OVERLAPPEDWINDOW,CW_USEDEFAULT,CW_USEDEFAULT,
        CW_USEDEFAULT,CW_USEDEFAULT,NULL,NULL,hInstance,NULL);
你指定 的类名不一致导致的，你lpszClassName写的事Action！，而你在CreateWindow中写的是Do it！
