How to implement OnDraw(), Serizalize()   

Hi, everyone,

I am a newbie to MFC and currently working on a project that needs to 
display file data and save opened files onto storage. After I created a MDI 
project and the default code had given me the basic frames and 
functionalities. When I open a file, a child window is opened with the 
filename on top. But no data is displayed. After reading the MSDN help 
information, I realize that I need to override OnDraw() method of CView, and 
Serialize() method of CDocument. Can anyone give me some example code 
implementing these two methods so to display and save file data? 
The example code in MSDN docs doesn't seem to be of much help. In OnDraw(), 
we get the file by calling GetDocument(), then what should we do to display 
the data in the document? 
In Serialize(), we need to add storing code and loading code, but what 
should they be? 

Thanks for your help.
