with bison have many %left's (+,*, etc) , few %right's (=, +=, etc). these tokens. have rule. its | rval | attrdata rval the problem is, attrdata rval returns rval attrdata 1+1 either (attrdata 1) +1 or attrdata (1+1). apply left rule attrdata doesnt work cause isnt token. tried %prec , error too. i can fix writing | attrdata '(' rval ')' dont want , rather have users write attrdata (1+1) since of time they'll mean (attrdata 1)+1. how give rule left precedence? the thing similar have else, solved forcing braces no confusion (if cond { if cond } else ) you can set explicit precedences may you if else example %nonassoc lower_than_else %nonassoc else %% stmt : if expr stmt %prec lower_than_else ; | if expr stmt else stmt;

file includes files b , c. c has access stuff defined in , b, c doesn't know that. how can tell c has access intellisense works? perhaps more clear example: if master.php includes library.php , page.php page.php has access library.php , there's no way page.php know that. want manually tell page.php library.php included, , have komodo save in meta data or project file. the basic answer that, depending on komodo settings, automatically gather (though in experience it's not 100% reliable). can set directories automatically import intellisense in ide settings. 2 places check: go edit->preferences->code intelligence in komodo ide , make sure 'include files , directories project base directory' go edit->preferences->languages->php , add other directories import zend framework, instance.

what easiest way save form data , retrieve when user navigates page? we have application process consists of several web forms. if user clicks go step auto-populate fields. assuming there common generic way without having mess individual controls - it? put forms on same page , enable viewstate. that is, instead of using 3 distinct pages, use single page has panels each of virtual "pages." keep track of page user on (with viewstate-managed property), , show/hide forms appropriate page. the next/back controls should post , increment/decrement current page. since it's same form, , it's posting itself, viewstate persist field values automatically. the thing won't work if click browser's "back" button. block using window.onbeforeunload prevent it.

i want have table track commissions due our wireless sales. each plan pays different commission, not problem. our reconciliation carriers don't pay (they may miss line or 2). the problem occurs when carriers change how pay commissions. want able go , see there 4 lines not paid in january @ commission rate x. feb same types of plans sold commission rates x-10. if change rate in commission table plan, when go pull data january report incorrect commission rates. i have table sales set date stamp thinking can cross reference somehow. hope followed this. i looking best way structure this. you should "stamp" record commission rate. either stamp actual rate every record... or keep commission id , put each record.

how can read register value variable 1 inline assembler command? using gcc on old freebsd system (v2.1 i386). i have such code: static volatile unsigned long r_eax, r_ebx; asm ("movl %%eax, %0\n" :"=r"(r_eax)); asm ("movl %%ebx, %0\n" :"=r"(r_ebx)); as result this: mov %eax,%eax mov %eax,0x1944b8 mov 0x1944b8,%eax mov %ebx,%eax mov %eax,0x1944bc mov 0x1944bc,%eax but need just: mov %eax,0x1944b8 mov %ebx,0x1944bc how can achieve result? this me (as long r_eax / r_ebx static) asm ("movl %%eax, %0\n" "movl %%ebx, %1\n" : "=m"(r_eax), "=m"(r_ebx)); beware that, unless specify assembly language statements within same asm() bracket, compiler might decide sorts of "interesting optimizations" in-between, including modifications these regs.

possible duplicate: java problem-whats reason behind , probable output long milli=24*60*60*1000; long micro=24*60*60*1000*1000; long result=micro/milli; the result should 1000 not. why work when use 24*60*60*1000*1000l ? can tell me reason this? the trouble calculation done on int s , casted long , , unfortunately 24*60*60*1000*1000 won't fit in int , wraps around. like long micro=24l*60*60*1000*1000; to force last multiplication done on longs.
