UC知道用VC++写了一个win32程序,运行时无响应(内有代码)?

少了这句：
winclass.lpszClassName=WINDOW_CLASS_NAME;
并且你这句应该是NULL：
winclass.lpszMenuName=WINDOW_CLASS_NAME;
语法很多行无用，并且写法很不好。。。
比如switch的clause中已经return了，还加了break;
你在CreateWindow后就直接return 了，当然没窗口显示
在while之前加上这两句
ShowWindow(hWnd, nCmdShow);
UpdateWindow(hWnd);
综合上面2位的意见....
