let's have trip planning application, , each trip composed of "path" resources (representing route driven, example) composed series of points. can crud these resources using requests (just example): post /trips/1234/paths <path> <point>32,32</point> <point>32,34</point> <point>34,34</point> </path> delete /trips/1234/paths/3 now consider want able split path 2 paths. in aobve example, might want pick point (32,34) split on, result in 2 paths - 1 ends @ point, 1 starts @ point. means single action creates 2 new resources, , simultaneously, deletes (the path split). so if path in example above path in system, , split single call, system contain 2 new paths , original gone. example: <path> <point>32,32</point> <point>32,34</point> </path> <path> <point>32,34</point> <point>34,34</point> </path> i'm struggling how handled r...

i using linq on view in sql server database. concrete sentence following: var valoresfiltrados = context.vdonotuse_v2.select(donotuse => donotuse).where(donotuse => donotuse.platformvalue.equals(platform) && donotuse.bank.equals(bank) && donotuse.languagevalue.equals("cze_cz")).orderby(donotuse => donotuse.id); where vdonotuse view's entity. sentece returning duplicated values (the first ids example 12170, 12171, 12170, 12171, 12204...) , values not ordered, can see in example. however, if use sqldataadapter following sentence (which sure equivalent linq one), works , returns correct values: "select * vdonotuse_v2 platformvalue = '" + platform + "' , bank = '" + bank + "' , languagevalue = 'cze_cz' order id asc" of course, both of them using same connection , database. does knows why happening? you need make sure have set entity keys in entity datamodel view correctly. fi...

the current, official compiler go (http://code.google.com/p/go/) uses handcrafted, arguably arcane code generator, includes injecting custom sections elf binary. this approach has spawned quite few bugs related utilities directly read and/or write elf information, such ldd , objdump or strip . i believe have been prevented using welltested crossplatform code generator, such llvm, , use linking facilities shipped os, such ld on unix/linux (or ld.exe on windows w/ mingw), or link.exe on windows visual studio. so why go use own code generator? reinventing wheel? or there more important reasons behind it? for information on how use gccgo, more traditional compiler using gcc end, see setting , using gccgo . the go language specification compiler agnostic. can choose available compilers, write 1 yourself, or contribute llvm go frontend project. for historical perspective on go compiler technology, read answer question: what compiler technology used build compiler...

so have 2 search bars, couple of buttons , tableview below (yes, these) in 1 view. , have navigation bar on top of button. for particular operation, remove search bars, buttons , display 1 uitableviewcell in view. if press edit, want whole view reloaded, not tableview want view have search bars , buttons , navigation screen. i did [self.view reloadinputviews] in ibaction of edit button. control goes here, view not reloaded. why? reloadinputviews used views firstresponders. self.view not first responder @ time. why want using "reloadinputviews", wouldn't easier use: [self.view setneedslayout] ?

i have object needs have 4-5 values passed it. illustrate: class swoosh(): spam = '' eggs = '' swallow = '' coconut = '' [... methods ...] right now, way use swoosh is: swoosh = swoosh() swoosh.set_spam('spam!') swoosh.set_eggs('eggs!') swoosh.set_swallow('swallow!') swoosh.set_coconut('migrated.') i'm having doubts whether pythonic or java influence. or necessary? also, in case you're wondering why i'm using setters instead of accessing object variables - basic validation has done there, hence set_ methods. i reckon provide different way initialize swoosh - provide __init__() accept dict / list ? anyway, i'm looking help/advice more experienced stuff. thanks in advance input on this. firstly you're using old style classes. really, really should using new style classes inherit object : class swoosh(object): defining __init__ method takes argume...

so use such script random int generation inside of range function randominrange(start, end) { if ((start >= 0) && (end >= 0)) { return math.round(math.abs(start) + (math.random() * (math.abs(end) - math.abs(start)))); } else if ((start <= 0) && (end <= 0)) { return 0 - (math.round(math.abs(start) + (math.random() * (math.abs(end) - math.abs(start))))); } else { return math.round(((start) + math.random() * (end - start))); } } you can see @ work here . positive ranges correct, negative correct bad , wrong results mixed. why , how fix it? i try use formula math.round(start + math.random() * (end - start)); ok, found problem, you're performing algebra on strings (since in code $('fnt').value value of input box, string), not numbers, things + end concatenating strings , not adding numeric content. in particular example, have: math.round(((start) + math.random() * (end - start))) which evaluates...

i have piece of code changes xslt of searchresultwebpart @ sharepoint 2010 search center result page (spfileitem - spfile of search result page) : splimitedwebpartmanager wpmanager = spfileitem.getlimitedwebpartmanager(personalizationscope.shared); foreach (webpart wpitem in wpmanager.webparts) { if (wpitem coreresultswebpart) { ((coreresultswebpart)wpitem).uselocationvisualization = false; ((coreresultswebpart)wpitem).xsl = somexsl; wpmanager.savechanges(wpitem); } spfileitem.update(); spfileitem.checkin(consts.checkincomment, spcheckintype.majorcheckin); but, code doesn't work if called on feature activated (gives invalidoperationexception - incorrect object state). works in console application. after reflecting, found out there piece of code inside searchresultwebpart, checks if webpart wasn't initialized - throws mentioned above exception on setting xsl property. know how work problem out? me it'd quite convenient xsl change @ featureac...

possible duplicate: what use of := syntax? i've tried hunting down mdsn documentation := in vb.net scoured google linked dead msdn page... purpose of := be? it names arguments, allowing call method arguments in order other specified in method definition. for example: sub foo (byval x long, byval y long) debug.print (string.format("{0}, {1}", x.tostring, y.tostring)) end function can called order of arguments reversed using names: foo (y:=999, x:=111) prints: 111, 999 this useful when have long list of optional arguments, want specify few of them, , want specify not first ones.

i'm bit confused; if object declared in .h file considered automatically "public" right? use @property in .h file, however, edit them? don't understand: use getter/setter private objects, why use @property objects declared in .h file , considered "public"? second thing, found example: don't understand why use @synthesize primarykey in code: http://staging.icodeblog.com/wp-content/uploads/2008/08/9-todom1.png , why don't use @property database object? it not correct if object (ivar) declared in .h file, public. if getter/setter methods provided, otherwise not. indeed, @property / @synthesize directives facilities meant declare , define default getter/setter methods. so, instead of writing them yourself, use directives. it worth noting declaring properties possibility of using dot notation refer properties of objects. , clarify lot, retain / assign / copy specifiers, how memory meant managed properties. (and, of course, @syn...

i'm writing workaround web form. given problem hitting submit pops out loading animation. content saved, form still shown, loading animation. the idea trigger event, 2-3 seconds after submit click, reset form content , hide loading animation. how suggest approach this? thank you. use callback functions in events chain them - way make sure action has completed, instead of trying run of them @ same time. if post code can more. there's .delay() function, think callbacks more appropriate, because process event driven , not time driven. have more flexibility in case in process goes wrong, instead of statically resetting after click.
