问题描述
喂，
我在做一个简单的人民币上下文菜单时遇到了魔鬼-我确信我对一些基本的东西误解了.尽管菜单显示在人民币上-最低菜单项的文本不显示-我只能看到竖线.但是，将第二级菜单悬停在关联的父菜单的垂直栏上时，显示会很好.附上有关情况的jpg，以防万一我不清楚自己的意思.
以防万一-我正在使用Windows Vista Home Premium(32位).
使用Visual C ++ 2008 Express编译
在此先感谢您为解决此问题提供的帮助.

Aloha,
I''m having a devil of a time trying to do a simple RMB context menu - and I''m sure I''m misunderstanding something basic. Although the menu displays on RMB - the lowest menu item''s text doesn''t display - I just get vertical bars. But the 2nd level menu displays fine when hovering over the associated parent menu''s vertical bar. A jpg of the situation is attached in case I''m not explaining myself clearly.
In case it makes a difference - I''m using Windows Vista Home premium (32 bit).
Compiled using Visual C++ 2008 Express
Thanks in advance for any help in solving this problem.
Aloha

推荐答案
尝试:
hMenu = CreatePopupMenu();
代替:
Instead of:
hMenu = CreateMenu();
CreateMenu用于创建菜单，您可以在标题栏下面看到.右键单击菜单是一个弹出菜单，因此应这样创建.
CreateMenu is used to create the menu you can see below the title bar. A right click menu is a popup menu, so it should be created as such.
