Answer 1

你的菜单在那里？？最好用菜单ID来加载菜单，用名字的方法你又搞不清楚来龙去脉...
你创建一个菜单时都会给你一个ID的，还有，你编辑菜单时直接用资源编辑器来做即可，没必要去手工编辑RC文件

Answer 2

这样的问题一般都只能通过和标准的程序比较才能知道问题所在，而且的问题出在参数上，比如有时传NULL对，而传hwnd就不对。

Answer 3

菜单是IDR_MENU 101
能麻烦能讲具体一点吗？谢谢。。新手上路。。

Answer 4

secwndclass.lpszMenuName = MAKEINTRESOURCE(IDR_MENU1); // 这样来加载菜单，IDR_MENU1是菜单的ID，在资源编辑器里可以看到
