CFileException::m_cause
Contains values defined by a CFileException enumerated type.
int m_cause;
Remarks
This data member is a public variable of type int. The enumerators and their meanings are as follows:
CFileException::none 0: No error occurred.
CFileException::genericException 1: An unspecified error occurred.
CFileException::fileNotFound 2: The file could not be located.
CFileException::badPath 3: All or part of the path is invalid.
CFileException::tooManyOpenFiles 4: The permitted number of open files was exceeded.
CFileException::accessDenied 5: The file could not be accessed.
CFileException::invalidFile 6: There was an attempt to use an invalid file handle.
CFileException::removeCurrentDir 7: The current working directory cannot be removed.
CFileException::directoryFull 8: There are no more directory entries.
CFileException::badSeek 9: There was an error trying to set the file pointer.

Note
These CFileException cause enumerators are distinct from the CArchiveException cause enumerators.
Note
CArchiveException::generic is deprecated. Use genericException instead. If generic is used in an application and built with /clr, the resulting syntax errors are not easy to decipher.
Example
try
{
CFile f(_T("M_Cause_File.dat"), CFile::modeWrite);
}
catch(CFileException* e)
{
if( e->m_cause == CFileException::fileNotFound)
TRACE(_T("ERROR: File not found\n"));
