The CStudioFile class is intended for WinCE MFC applications because MFC for 
WinCE did not implement the CStdioFile text file functions.  You should 
use the CStdioFile in Win32 programs.   
 
This class implements both UNICODE and ASCII text file reads and writes. If the 
format is UNICODE, it is assumed to contain 16-bit strings.  Other UNICODE formats  
cannot be read by WinCE programs. It is the caller's responsibility to know which format  
the file is in. 
 
Because of file buffering, programmers should not mix the CFile::Read and 
CFile::Write with the ReadString methods in this class.  Doing so will cause 
unpredictable results. 
 
CFile::typeText is stripped from the open flags when the Open method is called 
to avoid the ASSERT in the base class.  It is not necessary to include this  
flag when using the CStudioFile class.
