Dear List... A small correction to the response below... "OPPI" is NOT obsolete, merely the manner in which the linking to the Geosoft libraries is done has changed to use geogx.lib; I should have said that the old OPPI DLL used below was obsolete...

The bug was an erroneous check made on the input line number, which should have simply checked that the line number was not a dummy, instead of checking that it was >= 0. The work-around is simply to link with the latest version of geogx.lib as is shown in the example workspaces in your oasismontaj/gxdev/c directories (for example "/chanadd/chanadd.dsw".

Also, the SetLineNum_DB() function fails if a negative integer is passed in as the new line number. I have encountered Geosoft databases which contain negative line numbers, so they are obviously allowed, but why doesn't OPPI support setting negative line numbers ? Is this a bug. And is there a work-around ? Here's a sample piece of code which works fine if line numbers are positive but fails if they're negative: // Create line symbol vnLineHandle[nLine] = CreateSymbEx_DB(pGeo, &hDB, linenum_str, _l(DB_SYMB_LINE), _l(DB_OWN_SHARED), _l(DB_CATEGORY_LINE_FLIGHT),&nTemp); long nLineHandle = vnLineHandle[nLine]; // Lock the symbol LockSymb_DB(pGeo, &hDB, &nLineHandle,_l(DB_LOCK_READWRITE), _l(DB_WAIT_NONE)); // Generate a negative line number - just for testing. This causes the SetLineNum_DB() function to fail ! long nNewLineNum = -100+nLine; SetLineNum_DB(pGeo, &hDB, &nLineHandle, &nNewLineNum); // Unlock the symbol UnLockSymb_DB(pGeo, &hDB, &nLineHandle); GEO_ERROR; Thanks, Anthony. _______________________________________________________ More mailing list info http://www.geosoft.com/support/listserv/index.html _______________________________________________________ More mailing list info http://www.geosoft.com/support/listserv/index.html _______________________________________________________ More mailing list info http://www.geosoft.com/support/listserv/index.html
