In an application created with AppWizard, you have two options: change the       
                                                                                 
derivation of the current view, or create a new view and use the new view        
in                                                                               
your MDI application along with the original view.                               
                                                                                 
To create a new view, use ClassWizard to create a new class derived from         
CView. After the class has been created, the steps to use the new view or        
to                                                                               
modify the view provided by App Wizard are the same.                             
                                                                                 
1.  Modify the header file for the view class to change all references to        
CView to the name of the desired view class. In this example, the class is       
                                                                                 
derived from CScrollView.                                                        
Usually, this step involves changing the class the view class is derived         
from                                                                             
as follows:                                                                      
                                                                                 
                                                                                 
class CMyView : public CScrollView                                               
                                                                                 
                                                                                 
2.  Modify the implementation file for the view class to change all              
references to CView to the name of the desired view class. This involves         
changing the IMPLEMENT_DYNCREATE line as follows:                                
                                                                                 
IMPLEMENT_DYNCREATE(CMyView, CScrollView)                                        
        changing the BEGIN_MESSAGE_MAP as follows:                               
                                                                                 
BEGIN_MESSAGE_MAP(CMyView, CScrollView)                                          
                                                                                 
and changing any other references to CView to CScrollView.                       
                                                                                 
                                                                                 
3.  No further modifications are required if you are modifying a view            
created                                                                          
by App Wizard. If you create a new view, find the AddDocTemplate() call in       
                                                                                 
the CWinApp::InitInstance() function. The third parameter to
