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 No error occurred.
CFileException::genericException An unspecified error occurred.
CFileException::fileNotFound The file could not be located.
CFileException::badPath All or part of the path is invalid.
CFileException::tooManyOpenFiles The permitted number of open files was exceeded.
CFileException::accessDenied The file could not be accessed.
CFileException::invalidFile There was an attempt to use an invalid file handle.

CFileException::lockViolation There was an attempt to lock a region that was already locked.
CFileException::diskFull The disk is full.
CFileException::endOfFile The end of file was reached.
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, there will be syntax errors that 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)
