hi everybody,

I would like to create a MFC MDI application having one document
using a data file and displaying those data in several Views in
Separate MDI Child Windows:
 * The first view, associated to the first MDI Child Window will
   display data as an image (will be associated with the OPEN-FILE
   command)
 * The second view, associated to the second MDI Child Window will
   display the same data as a graph
 * The third view, associated to the third MDI Child Window will
   display the same data as column of text

Could somebody please tell me how to do that.

Thank you in advance

As you probably know, you'll need 5 classes: one document, one child frame, and
three views.  When the document is first opened, the CMultiDocTemplate will open
the document, and create a child frame with one of the views in it.  One
solution to opening subsequent views (there are other good methods) is to derive
a class from CMultiDocTemplate, and use that in InitInstance, in place of the
base class.  In your derived class, in CreateNewFrame, you can repeat the steps
of creating frame windows, substituting the other view classes each time.  Look
at the CDocTemplate::CreateNewFrame source in DocTempl.cpp.

Take a look at CHKBOOK sample in msdn. There are also many samples on
