This article was previously published under Q92803 SUMMARY
In an application developed with the Microsoft Foundation Classes
(MFC) that uses the CFile class, the Write() member function may
appear not to correctly process the carriage return-linefeed (CR/LF)
combination unless both the carriage return and linefeed are
explicitly stated.
For example, the following code
CFile file;
// ...
file.Write("Hello\n", 6);
file.Write("Hello\n", 6);
produces the following output:
-------------------
Hello
Hello
-------------------
However, the following code
file.Write("Hello\n\r", 7);
file.Write("Hello\n\r", 7);
produces the following output:
-------------------
Hello
Hello
-------------------
MORE INFORMATION
When an application uses the CStdioFile class derived from CFile, an
application can open a file in either text mode or binary mode. Using
a CStdioFile object is the preferred method to place a CR/LF
combination into a file. However, if the application must use a CFile
object, a CR/LF combination may be explicitly output as demonstrated
above.
