SUMMARY
=======
The TEXT sample demonstrates how to display and print text using a CScrollView
derived class. It is possible to implement text output in a CScrollView class by
overriding OnDraw and drawing the entire document using TextOut. However,
further steps are required to draw the text efficiently and to include support
for multipage documents. Here are the features implemented in this sample and
the locations:
