// Set Connection Info ITDBInfo database; database.SetUser(dbuser); database.SetPassword(dbpassword); database.SetSystem(dbinstance); database.SetDatabase(dbname); // Connect ITConnection conn; if ( !conn.Open(database) ) { printf("%s:Error: Failed to connect to the database\\n",dbinstance); // Would like to print error error_number:text. The message above does not // help to tell me why the connection failed }; How to trap error message from conn.Open(database). I would like to see the error message that is generated when I'm not able to connect ??
