The code of previous question came right of out of an MFC generated app
for the OnNewDocument, with Doc/View support and CEditView being the base
class. I probably
should have show the whole sequence to eliminate ambiguity. But anyhow if
I understand you correctly then the code is calling
((CEditView*)m_viewList.GetHead()) so as to point to the correct window to
set text ?
See this is one of the main areas of my confusion so far. I'm used to
dealing with window
handles. I'm still struggling with how to connect with the correct window
without a hwnd.
But I think you have helped me along my way with some more practice and
printouts

In MFC a window is accessed with a pointer to the associated CWnd-derived
object, instead of using window handles. If you peek inside an MFC function
like CWnd::SetWindowText you will see a little one-line function like
::SetWindowText(m_hWnd, ...), so MFC is merely hiding the handle (m_hWnd)
inside a C++ object.

!!! While !!!
I'm here can you guys give me some insight on where I should declare an
instance
of a generic class that I created ? Does it matter or should I instance it
in the MainFrame.cpp.? I'm somewhat confused with a WinMain function. If
it does not
need global scope then I can instance it where ever I want correct ?
Thanks to all replies, as usual all you all have been a tremendous help to
a struggling learner of C++ and MFC.

Yes, you can add a generic class anywhere you want. Making it a member of
the CDocument is probably the most common place, because views have easy
access to the associated CDocument. That's the place for "data."
