<p class=MsoNormal><font size=2 face=Arial><span lang=EN-AU style='font-size:
10.0pt;font-family:Arial'>I have had considerable frustrations with developing
under Visual C++ 6.0 using MFC. In looking through the postings on the
newsgroup, the major problems lie in vtkMFC* and, also for new users, how to
integrate these classes into an application. </span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span lang=EN-AU style='font-size:
10.0pt;font-family:Arial'>So, I decided to revisit the whole problem and
develop without using the vtkMFC* classes. In fact it turned out to be quite
simple to just create a project and modify some of the methods to yield a full
blown application that also has printing enabled. </span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span lang=EN-AU style='font-size:

application you only have to modify the constructor, destructor and pipeline
for the view. This was a big surprise! </span></font></p>
