why do you want to call Bar and Pimpl in method Test of class Y? If we put something (like Bar) in Pimpl part, it means it is not visible. So, I think it does not make senses to access Bar if it is in Pimpl part. Any comments?

class CTestDlg : public CDialog  // class Y : public X
{
protected:
  virtual BOOL OnInitDialog(void);
  // ...
};
BOOL CTestDlg::OnInitDialog()
{
  // ...
  CMenu* pMenu = GetSystemMenu(FALSE); // This is something like invoking X::Bar().
  // ...
}

I think you can still access Foo in class Y, right?

Do you mean the pattern of MFC dialog is good or not?

George_George wrote:

Does it relates to my original question?

In the ANSI version of this function, the name is limited to MAX_PATH characters. To extend this limit to 32,767 wide characters, call the Unicode version of the function and prepend "\\?\" to the path. For more information, see Naming a File[^].
