我在CDialogBar上有一个CMFCMenuButton，它有一个非常奇怪的行为：它在Debug构建中显示其下拉列表，但在发布版本中不显示。

发布版本：

似乎在OnShowMenu（）的__super :: OnShowMenu（）的调用中发生错误，我的派生类的方法。

It seems that there is happening something wrong in the call of __super::OnShowMenu() of the OnShowMenu() method of my derived class.

为了使事情变得更糟，我的机器上有一些配置没有进入MFC功能包方法...我做了一切把这个工作，我无法到达那里。

To make thing worse, there is some configuration on my machine that is not stepping into the MFC feature pack methods ... I made everything to put this working and I could not get there.

请帮助。

推荐答案

对不起，这是我的错误：

Sorry, it was my mistake:

在我的派生类OnShowMenu函数中，我不得不替换：

On my derived class OnShowMenu function, I had to replace:

pMyMenu= new CMenu;
ASSERT(pMyMenu->CreatePopupMenu());
this->m_hMenu= pMyMenu->GetSafeHmenu();

与此：

pMyMenu= new CMenu;
pMyMenu->CreatePopupMenu();
this->m_hMenu= pMyMenu->GetSafeHmenu();

是的，该错误是由ASSERT引起的。

Yes, the bug was caused by the ASSERT.
