OnInitialUpdate( ) is a virtual view function Called by the
framework after the view is first attached to the document,
but before the view is initially displayed. The default
implementation of this function calls the OnUpdate member
function
OnUpdate() is called by the framework when the doc has been
modified.It is actually called by UpdateAllViews() to
reflect changes in all the views associated with the doc.

implemenation calls OnUpdate function. if the window is
resizable or it has scroll bars, use OnUpdate() to change
the scroll limits and document changes.
