◄CFile► ◄Up► ◄Contents► ◄Index► ◄Back► ──Microsoft Foundation Classes────────────────────────────────────────────── virtual BOOL Open( const char* pszFileName, UINT nOpenFlags, CFileException* pError = NULL ); Parameter Description <pszFileName> A string that is the path to the desired file. The path may be relative or absolute, but may not contain a network name. <nOpenFlags> A UINT that defines the file's sharing and access mode. It specifies the action to take when opening the file. You can combine options by using the bitwise-OR (|) operator. One access permission and one share option are required; the modeCreate and modeNoInherit modes are optional. See the ◄CFile► constructor for a list of mode options. <pError> A pointer to an existing file-exception object that indicates the completion status of the open operation. Remarks Open is designed for use with the default CFile constructor. The two functions form a "safe" method for opening a file where a failure is a normal, expected condition. The constructor is guaranteed to succeed, and Open returns (a pointer to) an exception object, bypassing the THROW/TRY/CATCH mechanism. Return Value TRUE if the open was successful; otherwise FALSE. The <pError> parameter is only meaningful if FALSE is returned. Example CFile f; CFileException e; char* pFileName = "test.dat"; if( !f.Open( pFileName, CFile::modeCreate | CFile::modeWrite, &e ) ) { #ifdef _DEBUG afxDump << "File could not be opened " << e.m_cause << "\n"; #endif } See Also ◄CFile::CFile►, ◄CFile::Close► -♦-
