error C2601: 'Winsunproc' : local function definitions are illegal为什么总是出现这个

Answer 1

MSG msg;
{
后面的大括号删掉。。。
=>
MSG msg;
while (GetMessage(&msg,NULL,0,0))
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
return 0;
}

另外：。。。。
1.所有的hwnd，注意，w应该是大写的(参数传进来的就是大写，你自己写的)。
2.hdc定义和使用大小写也不一致。
3.break后面是分号。。。

追问

改了还是有错 break;
case WM_DESTROY:
PostQuitMessage(0);
break;
default:
return DefWindowProc(hWnd,uMsg,wParam,lParam);
}
}
return 0;
}
