// Test Whether the dir exist CString m_dir; if (m_dir.Right(1) == “\\”) m_dir = m_dir.Left(m_dir.GetLength()-1); if (GetFileAttributes(m_dir) == FILE_ATTRIBUTE_DIRECTORY) return TURE; else CreateAllDirectory(m_dir); // Function CreateAllDirectory // recursive function void CreateAllDirectory(CString Dir) { if (Dir.Right(1) == “\\”) Dir = Dir.Left(Dir.GetLength()-1); if (GetFileAttributes == FILE_ATTRIBUTE_DIRECTORY) return; else if (GetFileAttributes(Dir) != -1) { if (DeleteFile(Dir)) // delete the file with the same name if (CreateDirectory(Dir, NULL)) return; MessageBox(_T(“Can not create directory for captured pictures”), NULL, MB_OK); } int n = Dir.ReverseFind(‘\\’); CreateAllDirectory(Dir.Left(n)); if (!CreateDirectory(Dir, NULL)) MessageBox(_T(“Can not create directory for captured pictures”), NULL, MB_OK); } 考试大提示判断Dir中某个文件是否存在,还可以通过FileFind来实现: BOOL FileExist(CString strFileName) { CFileFind fFind; return fFind.FindFile(strFileName); } |
