Examples of errors detected by the V762 diagnostic

V762. Consider inspecting virtual function arguments. See NN argument of function 'Foo' in derived class and base class.


Notepad++

V762 It is possible a virtual function was overridden incorrectly. See first argument of function 'redraw' in derived class 'SplitterContainer' and base class 'Window'. splittercontainer.h 61


class Window
{
  ....
  virtual void display(bool toShow = true) const
  {
    ::ShowWindow(_hSelf, toShow ? SW_SHOW : SW_HIDE);
  }

  virtual void redraw(bool forceUpdate = false) const
  {
    ::InvalidateRect(_hSelf, nullptr, TRUE);
    if (forceUpdate)
      ::UpdateWindow(_hSelf);
  }
  ....
}

class SplitterContainer : public Window
{
  ....
  virtual void display(bool toShow = true) const; // <= good

  virtual void redraw() const;                    // <= error
  ....
}

Similar errors can be found in some other places:
