MFC CMenu工具提示未显示

Question

我试图用这样的东西来设置的CMenu项的工具提示(如描述在这里),但它只是显示在一个单一的线和换行符是不可见的.

// read control id
UINT id = menu->GetMenuItemID(1235);
// modify caption and add tooltip?
menu->ModifyMenu( id, MF_BYCOMMAND, id, "Click here\nThis is the tooltip for the menu item ...");

我还尝试直接在菜单项的visual studio资源设计器中设置标题,效果相同.你能给我任何关于什么错误的提示吗？我在Windows 7上使用VS2008.

任何帮助表示赞赏!

也许您还没有将 windows xp 常用控件添加到您的应用程序中。

尝试将通用控件添加到 stdafx.h 中：
