How to overwrite OnFileSaveAs?

[Damir Cosic]

I would like to write my own OnFileSaveAs, but I encountered some problems. I tried to implement this message handler in different classes (CMainFrm, CView, ...), but it didn't work. Then I found in Technical Note 22 and another article that this command message is 'prewired' to CDocument class. So I guess my question is how to 'unwire' that message and use it as I want.

Thanks.
