Answer 1

什么没反应？
就是Windows入门的代码。

Answer 2

TCHAR lpszClassName[]=L"TEST";//窗口类名
TCHAR lpszTitle[]=L"WAHAHA";//窗口标题名
//窗口的定义
wndclass.style=0;
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=lpszClassName;
//窗口的注册if(!RegisterClass(&wndclass))
{MessageBeep(0);
return FALSE;
}
//创建窗口
hwnd=CreateWindow(
  lpszClassName,
  lpszTitle,
  WS_OVERLAPPEDWINDOW,
  CW_USEDEFAULT,
  CW_USEDEFAULT,
  CW_USEDEFAULT,
  CW_USEDEFAULT,
  NULL,
  NULL,
  hInstance,
  NULL
  );修改了一下，窗口类名要指定正确

Answer 3

就是这里要改
wndclass.lpszClassName=lpszClassName;

Answer 4

wndclass.lpszClassName=NULL;
//窗口的注册改成
wndclass.lpszClassName=lpszClassName;
