无效定义，编译过了，界面就是不出来？
在C中建立一个菜单，但是就显示时里的项目是无效的定义，此问题1，问题了，就是将这些问题//取消掉，单单只是窗口一运行就退出，怎么也看不出那里错，报错是:The thread 0xD5C has exited with code 10 (0xA).
Menu.exe ' has exited with code 0 (0x0).

全部的程序如下：第一个问题的报错如下：

# include <string.h>
# include "menu.h "
# include "resource.h "

[解决办法]
界面不出来可能原因很多，DEBUG一下，看看HWND的值。
