Files in MFC
In the Microsoft Foundation Class Library (MFC), class CFile handles normal file I/O operations. This family of articles explains how to open and close files as well as read and write data to those files. It also discusses file status operations. For a description of how to use the object-based serialization features of MFC as an alternative way of reading and writing data in files, see the article Serialization.
When you use MFC
CDocument objects, the framework does much of the serialization work for you. In particular, the framework creates and uses the
CFile object. You only have to write code in your override of the
Serialize member function of class
CFile class provides an interface for general-purpose binary file operations. The
CMemFile classes derived from
CFile and the
CSharedFile class derived from
CMemFile supply more specialized file services.
For more information about alternatives to MFC file handling, see File Handling in the Run-Time Library Reference.
For information about derived
CFile classes, see the MFC hierarchy chart.
