<br>主题：关于动态创建菜单的小问题
<br>内容：我想动态建菜单，用的是如下代码：<BR>&nbsp;&nbsp;&nbsp;&nbsp;CWnd *pParent=GetParent();<BR>&nbsp;&nbsp;&nbsp;&nbsp;CMenu *pMenu=pParent-&gt;GetMenu();<BR>&nbsp;&nbsp;&nbsp;&nbsp;CMenu *SubMenu=pMenu-&gt;GetSubMenu(5);<BR><BR>&nbsp;&nbsp;&nbsp;&nbsp;SubMenu-&gt;AppendMenu(MF_STRING|MF_ENABLED,New_Lap_ID++,“1”);<BR><BR>但是所建的菜单不能如图所示的那样，在y菜单的下拉菜单里。1,2,3为要动态添加的菜单。<BR>因为我不能用GetSubMenu获得指向y菜单的指针，因为参数不允许。我该怎么办呢？<BR><BR>谢谢各位指点。<BR><BR>

<br>内容：CreatePopupMenu()<BR>这是MSDN中的一个例子，对你或许有帮助<BR>// The code fragment below shows how to create a new menu for the<BR>// application window using CreateMenu() and CreatePopupMenu().<BR>// Then, the created menu will replace the current menu of the<BR>// application. The old menu will be destroyed with DestroyMenu().<BR>// NOTE: The code fragment below is done in a CFrameWnd-derived class.<BR><BR>// Create a new menu for the application window.<BR>VERIFY(m_NewMenu.CreateMenu());<BR><BR>// Create a "File" popup menu and insert this popup menu to the<BR>// new menu of the application window. The "File" menu has only<BR>// one menu item, i.e. "Exit".<BR>VERIFY(m_FileMenu.CreatePopupMenu());<BR>m_FileMenu.AppendMenu(MF_STRING, ID_APP_EXIT, (LPCTSTR)"E&amp;xit");<BR>m_NewMenu.AppendMenu(MF_POPUP, (UINT) m_FileMenu.m_hMenu, "&amp;File");<BR><BR>// Remove and destroy old menu<BR>SetMenu(NULL);<BR>CMenu* old_menu = CMenu::FromHandle(m_hMenuDefault);<BR>old_menu-&gt;DestroyMenu();<BR><BR>// Add new menu.<BR>SetMenu(&amp;m_NewMenu);<BR><BR>// Assign default menu<BR>m_hMenuDefault = m_NewMenu.m_hMenu;
