推荐答案

正如你所说的一篇文章，请在底部添加评论。

作者将收到通知并回复。

As you are referring one Article, then please add a comment at the bottom.
The author will get notified and reply you back.

如果查看afxwin.h文件， CDocument 类实现确实有这些调用。不确定为什么MS没有记录它们但是它们就在那里。



DoSave标记为：

If you look at the afxwin.h file, the CDocument class implementation does have those calls. Not sure why MS doesn't document them but they're there.

DoSave is under a section labeled as:

// implementation helpers

和其他两个在：

and the other two are under:

// file menu commands

没有 OnSave ，但有 OnSaveDocument ：

为什么你可能需要帮助才能覆盖？如果一个函数是虚函数（并且上面提到的函数是虚函数），我希望你知道如何覆盖它。如果不是，你根本无法覆盖它？这些东西可能需要帮助吗？



另一方面，文章的作者负责，无论是否能与这个人联系。我有一个问题要问：您是否要开始自己编写代码而不是阅读其他人提供的代码并使用它？或者你已经做到了？然后专注于它。和其他人一起玩代码并不是最有效的做事方式或学习方式。

There is no OnSave, but there is OnSaveDocument:

And why would you possibly need help on overriding? If a function is virtual (and the function mentioned above is virtual), I hope you know how to override it. If it is not, you cannot override it at all? How such stuff may possibly need any help with?

On the other detail, the author of the article is responsible, no matter if can reach this person or not. I have a question for you: are you going to start writing code by yourself instead of reading code offered by others and playing with it? Or you already do? Then focus on it. Playing with other people's code is not the most productive way of doing things or learning.
