Thanks Joe,

So further, because a CFormView is just a wrapper to manage a dialog. Then
the terms form a dialog ARE synonymous (as I noted in one of my
references)?

No, a CFormView is a wrapper to manage a dialog template. A CDialog is also
a wrapper to manage a dialog template. The term "form" is used in other
environment and is not well defined in MFC.

So I can say that a CFormView is View based application because it has the
doc-view framework. This framework incorporates the IsModified() and
m_bModified to allow automatic updates of the document from the view and
vice-versa.

However, dialogs typically use DDX and therefore, the full utilization of
the doc-view framework is not realized in FormView. Is that a fair
statement?

DDX is used identically in CDialog and CFormView.

In fact in the FormView apps I have seen, the data is handled at the
control
level. That is, OnSelChange() handler will just take the appropriate
action
on a data-pool (structure, class, link-list, etc). There really is no DDX
or
IsModified() stuff going on.

DDX is used identically in CDialog and CFormView. IsModified is a feature
unique to doc/view.
