RE: [geonet]: Lines extracted in random order?

[Ian MacLeod]

Hello Bob,   One way to do this is to call the SymbLST_DB function to get a list of DB_SYMB_LINE objects, sort the list of lines using Sort_LST, then go through the list in order.  You get the line symbol from the value part of the LST as a number string and cast the converted value to a line symbol to get the line, something like (untested):   hLST = Create_LST(127); SymbLST_DB(hDB,hLST,DB_SYMB_LINE); Sort_LST(hLST,0,0);   iLines = iSize_LST(hLST); for (iLine=0;iLine<iLines;iLine++) {       GetItem_LST(hLST,1,iLine,sLine)     hLine = (DB_SYMB)iScan_STR(sLine);       ...   }   Regards, Ian _______________ Geosoft Inc.

Hi,   I am extracting data from a gdb in a standalone C program using the prototype code:      hLine = FirstSelLine_DB(pGeo,&hDB);    do {       if (!iIsLineValid_DB(pGeo,&hDB,&hLine)) break;       iLineN = iLineNumber_DB(pGeo,&hDB,&hLine);         ….some processing ….         hLine = NextSelLine_DB(pGeo,&hDB,_l(hLine));    } while (1);   The problem is that the lines are extracted in “random” order and not sequentially with respect to line number. Is there a method for extracting the lines in sequential line number order?   Thanks in advance for any help,   Regards, Rob   Robert G Ellis Minerals Discovery Group, BHP World Exploration Inc. 1111 West Georgia Street, Suite 1400 Vancouver, BC, Canada, V6E 4M3 Telephone: (direct) 604 632 1470  (reception) 604 632 1450 Fax: 604 683 4125 EMAIL: [EMAIL PROTECTED]
