• For those functions (and constructors, etc.) that are defined in the header, prepend an inline qualifier at the declaration.
  
• Enclose the definitions into a guard like this:

  #ifndef _AFXEXT
  ... // offending definitions
  #endif

CFile   file1("c:\\testfile.txt", CFile::modeRead),
        file2("c:\\testfile.tmp", CFile::modeWrite | CFile::modeCreate);
CString strLine;
 
while (file1.ReadString(strLine))
{
    strLine.Replace("1234", "56");
    file2.WriteString(strLine);
}
 
file1.Close();
file2.Close();
 
CFile::Remove("c:\\textfile.txt");
CFile::Rename("c:\\testfile.tmp", "c:\\testfile.txt");
