i have prolog code data.pl , , need use php file. search in internet, found this: exec('start <path/to/prolog> -f data.pl -g elem(a,[a,b])', $output) i've tried shell-exec() , system() commands, not work either. i've tried correct directory paths, , move data.pl path/to/prolog folder, , still no result. can me on issue? a better approach integrating web application prolog application can using swi's built-in http server. spare need load prolog , parse input file every call. provides more web-ish integration, can use ajax , similar approaches. if insist on invoking prolog executable php runtime env., you'll have provide more details. errors in php logs? have checked file permissions? did try giving full paths both prolog executable , data file? saying "it doesn't work" statement, not question. finally, efficiency issues, advisable compile prolog data file quick load format (qlf) instead of re-parsing each request

i have function: void writemap(object value) { idictionary<string, object> vv = (idictionary<string, object>)value; foreach (keyvaluepair<string, object> obj in vv) { (write key) (write value) } } it works if value of type idictionary<string, object> , like: idictionary<string, int> idictionary<string, myclass> idictionary<string, string[]> etc. the cast throws run-time exception. function not modify container, prints keys , values. ideas on how can make work? appreciated. thanks! add generic type parameter method corresponding type of values in dictionary: void writemap<t>(idictionary<string, t> dict) { foreach (keyvaluepair<string, t> in dict) { // write key // write value } } this has advantage of eliminating cast. if need pass dictionary in object reason, cast idictionary .

i new neo4j & playing learn in deep. have small doubt like, if created 2 nodes in space , provided relationship , system time (to know @ time friends each other) between 2 nodes. so question is, possible 2 different relation times (if provide direction both & created relation once)? you people knows how traverse function behaves in neo4j. if please explain me example how ? your question not entirely clear. if have (person) - knows [started = time] -> (person) then can have many of relationships you'd like, in either direction (both means 2 relationship, 1 in either direction). for direct relationships do: node me, you; (relationship r : me.getrelationships(knows)) { if (r.getothernode(me).equals(you)) result.add(r.getproperty("time")); } for longer paths can use graphalgofactory.allsimplepaths retrieve paths between 2 people , relationships , time information whatever want. hth michael

i all, have win32 application , several dlls must use global variable. in each dll put extern mytype* myvariable = null; and in main program have mytype* myvariable = null; mavariable = new mytype(); .... now, when dlls loaded myvariable null , cannot use it. how can share instance of main program dlls? you should make changes in program. if possible can move myvariable exe 1 dll. can continue use import libraries. it general can export functions or data exe, in cases there less sense this. can see seldom. example winword.exe or excel.exe this. if need export frunction or data exe , use in dll should use dynamical binding respect of getprocaddress , getmodulehandle(null) . can such kind of manual binding inside of dllmain . address of myvariable of exe can save in local myvariable of dll.

how save iplimage of opencv flash file? maybe there library that? if mean storing output flash video (.flv) use ffmpeg (libavcodec/libavformat). cross platform , supports .flv format (besides massive amout of others) , should quite easy do. can embed audio too. as note: ffmpeg partially included in opencv (depending on build) video coder/decoder, don't know though if can force write .flv (by choosing right codec string) within opencv. anyways it's not hard convert iplimage ffmpeg buffer , store there. a problem might have latest opencv (2.1) has trouble build ffmpeg support or build against ffmpeg version don't want. mentioned above don't need use ffmpeg via opencv 2.1 api, since can use directly using ffmpeg api. look examples in libavcodec on how write video, , check opencv source on how convert iplimage avpacket/avframe. i've done before , quite easy do.

i have programmed in both java , c, , trying hands dirty c++. given code: class booth { private : int tickets_sold; public : int get_tickets_sold(); void set_tickets_sold(); }; in java, wherever needed value of tickets_sold , call getter repeatedly. for example: if (obj.get_tickets_sold() > 50 && obj.get_tickets_sold() < 75){ //do } in c value of particular variable in structure: if( obj_t->tickets_sold > 50 && obj_t->tickets_sold < 75){ //do } so while using structures in c, save on 2 calls otherwise make in java, 2 getters is, not sure if actual calls or java somehow inlines calls. my point if use same technique used in java in c++ well, 2 calls getter member functions cost me, or compiler somehow know inline code? (thus reducing overhead of function call altogether?) alternatively, better off using: int num_tickets = 0; if ( (num_tickets = obj.get_ticket_sold()) > 50 && nu

what ( real | significiant ) difference (s) between adt list implementation , linked list implementation with respect queue ? moreover, can suggest website visual example of these type of lists ? it hard understand question, in attempt ask actual question is, believe have figured out. assumption is, question is: "what difference between std::list , std::queue. @fatai: please correct me, when wrong. the std::list doubly-linked list. each element of list "knows" next , previous element. , list "knows" it's beginning , end. here: http://www.cplusplus.com/reference/stl/list/ the std::queue list, special functionality. functionality allows insert elements @ front, , remove elements back. have here: http://www.cplusplus.com/reference/stl/queue/ if want have minimal functionality, i'd use queue. queue optimized purpose. prevents doing things accidentally wrong (such remove element middle). i hope answers (confusing) question. ;-)

i'm wondering under circumstances code breaks in second assert. in other words, when can -[uiimage cgimage] return nil ? documentation isn't telling here. - (void)setimage:(uiimage *)animage { assert(animage); cgimageref cgimage = animage.cgimage; assert(cgimage); } i'm pretty sure, uiimage correct since it's fetched app bundle. far haven't been able reproduce case see user crash reports. another possibility have multiple threads accessing same uiimage object @ same time; happening in code same symptom. that might explain sporadic crash reports, too, since access patterns depend on timing changes run run.
