为什么我通过调用CMFCRibbonBar :: RemoveCategory()删除类别后清除了CMFCRibbonBar :: m_hWnd [英] why the CMFCRibbonBar::m_hWnd was cleared after I removed a category by calling CMFCRibbonBar::RemoveCategory()

问题描述

亲爱的所有人

现在，我创建了一个MFC应用程序并使用了功能区UI，它看起来很酷，但是我遇到了一个问题，但是还没有找到答案.
看起来像这样:

我在功能区中添加了一些类别，当销毁框架窗口时，我尝试通过CMFCRibbonBar :: RemoveCategory()删除指定的类别，但是我发现CMFCRibbonBar :: m_hWnd之后在调试中将其更改为0，并在以后导致异常.谁能提供一些想法?
