Public Methods   ResourceDb ()   ~ResourceDb ()   ResourceDb (char *resName, Database *dbObj, int indexOffset, int useCommonBuf=0) void  init (char *, Database *, int, int=0) void  deinit () char *  read (int=-1) File *  get_file () void  init_imported (char *, int, int=0) char *  read_imported (long) Public Attributes char  init_flag Detailed Description Implementation of a resource using a database (file) as the data source. Database resource files are built by LIBDB.EXE, it is always have a .RES extension. Definition at line 18 of file ORESDB.H.

File * ResourceDb::get_file (    )    Position the file pointer to the beginning of the data and return the file stream Syntax : get_file() Return : <FILE*> the file stream NULL if the record has not index to data Definition at line 123 of file ORESDB.CPP. References NULL. void ResourceDb::init (  char *    resName, Database *    dbObj, int    indexOffset, int    useCommonBuf = 0 )    <char*> resName = name of the resource file (e.g. "GIF.RES") <Database*> dbObj = name of the database (e.g. Database db("PFILE.DBF")) <int> indexOffset = offset of the index field [int] useCommonBuf = whether use the vga common buffer to store the data or not (default:0) Definition at line 29 of file ORESDB.CPP. References NULL. Referenced by ResourceDb(). void ResourceDb::init_imported (  char *    resName, int    readAll, int    useCommonBuf = 0 )    If the whole database has been read into memory, then only no need to tell ResourceDb the database name and the index offset <char*> resName = name of the resource file (e.g. "GIF.RES") <int> readAll = whether read all data into the buffer or read one each time [int] useCommonBuf = whether use the vga common buffer to store the data or not (default:0) Definition at line 155 of file ORESDB.CPP. References NULL. char * ResourceDb::read (  int    recNo = -1 )    Read in data from the resource file and store in an the buffer of this class The index field of the current record in the database object is used to locate the data in the resource file. Syntax : read(int recNo) [int] recNo = the record no. in the database. (default : current record no.) Return : <char*> data pointer NULL if the record has not index to data Definition at line 84 of file ORESDB.CPP. References COMMON_DATA_BUF_SIZE, and NULL. char * ResourceDb::read_imported (  long    offset )    If ResourceDb is initialized using init_imported(), then use read_imported to read the record <long> offset = offset to the data in the resource file Return : <char*> data pointer NULL if the record has not index to data Definition at line 198 of file ORESDB.CPP.
