[解决办法]
ShowWindow (hwnd, iCmdShow) ;

UpdateWindow (hwnd) ;

这两句话跑哪里去了？我没有看到。。。
[解决办法]
很正常
你没写显示代码
就像上面的大哥那段代码你没写
if(!(hwnd1 = CreateWindowEx(NULL,
WINDOW_CLASS_NAME_2,
"YOUR BASIC WINDOW ",
WS_OVERLAPPEDWINDOW | WS_VISIBLE,
0, 0,
400, 400,
NULL,
NULL,
hinstance,
NULL)))
return (0);
后面写即可
ShowWindow (hwnd, iCmdShow) ;
UpdateWindow (hwnd) ;
