i want write gui code orthogonal. lets have circle class , square class , need interact. right now, circle , square talking each other - circle object sends message square object, use square_obj.listen_for_circle(circle_obj) listen_for_circle method implements addlistener. this problem me since 2 objects linked - , removing 1 object code break it. looking circle_obj able broadcast global message 'circle_event' . additionally square_obj listening global message broadcasts of type 'circle_event' , , upon hearing event - action.(ahhh, objects have no links each other in code base!) is possible or reasonable in matlab? (or maybe i'm going crazy). always, advice appreciated. i'm not sure why addlistener problematic you. adds event listener doesn't if event-origin object (the circle) deleted. alternately can use event.listener or handle.listener . undocumented work well, , used within matlab codebase (m-files). see explanation here: http://u...

here 2 methods in view controller apple tutorial: - (void)viewdidunload { self.eventsarray = nil; self.locationmanager = nil; self.addbutton = nil; } - (void)dealloc { [managedobjectcontext release]; [eventsarray release]; [locationmanager release]; [addbutton release]; [super dealloc]; } couldn't dealloc method shortened following? if not, why not? - (void)dealloc { [managedobjectcontext release]; [super dealloc]; } - (void)viewdidunload not guaranteed called, should release things in dealloc too. see this question find out when it's called, , should when is.

i need fields list template? how can this? var web = site.openweb(); var template = web.listtemplates["sometemplate"]; template ... ???? -there no method fields. there no built-in method fields list template. way can fields parsing schema xml of list , getting <field> , <fieldref> tags. easier create list instance, can query later on following examples. to fields list can use splist.fields property, e.g. so: foreach (spfield spfield in mylist.fields) { //your code here } msdn splistitem.fields you can fields list item "in reverse" splistitem.fields property . might interested in thread: check if list column exists using sharepoint client object model?

i'm trying implement comet (xhr streaming) node.js. since, xhr streaming make client side xhr.responsetext keep growing, necessary client side close current xhr , restart xhr streaming again. in server side, each xhr streaming, http.serverresponse object should held until http session over. the problem is: how can node.js detect browser side has ended 1 http session? i thought, ideally, there 1 callback argument http.serverresponse.write. writing closed http session trigger callback , let know aborted. but, there no such callback argument. i think http://socket.io/ need client.on('disconnect', function(){ … })

i have created base-controller controllers inherit. controller fills data (which use in views) viewdata -container this: protected override void initialize(system.web.routing.requestcontext rc) { base.initialize(rc); viewdata["cms_configuration"] = new cmsconfiguration(); // etc. } i don't fact need read (and cast) viewdata within views. i'd introduce baseviewmodel viewmodels inherit from, defining properties instead of using viewdata. how or can populate baseviewmodel within basecontroller? there kind of hook? or need define function in basecontroller, call in child-controller? e.g. (child-controller: //{...} base.populatebaseview(myview); return view(myview); thx tipps. sl3dg3 you optionally use actionfilters stuff this: check out article: http://www.asp.net/mvc/tutorials/understanding-action-filters-cs it explains actionfilters nicely. way can separate different populate-logic different filters, , tur...

i have 2 tables wish update articles , articles_entities articles has pk of id , articles_entities has fk article_id both these fields char(36) uuid. looking convert these fields int(10). is there way can update 2 tables 1 query , key keys matching? or have write script through each articles , update references? i using innodb if helps. two steps: ensure foreign key set "on update cascade", update mother table's id field contains numbers. on update cascade constraint have innodb update child table updates mother... if have lot of rows, prepared extremely slow. change type of both columns int. may need drop foreign key before , re-create afterwards.

what difference between javascript's window.location.href = window.location.href and window.location.reload() functions? if remember correctly, window.location.reload() reloads current page post data, while window.location.href=window.location.href not include post data. as noted @w3max in comments below, window.location.href=window.location.href not reload page if there's anchor (#) in url - must use window.location.reload() in case. also, noted @mic below, window.location.reload() takes additional argument skipcache using window.location.reload(true) browser skip cache , reload page server. window.location.reload(false) opposite, , load page cache if possible.

how architecture android app like? should "work/business logic" been done in background service , activity communicates service query/fetch data somewhere (local/distant)? would implement "service" activity calls real android-service? or pojo-singleton work (perhaps using background threads). or instantiate background threads in activity time-consuming actions (query webservice). how abstract data access right way? use contentprovider access/abstract data? how/from should queried? activity? service? ..? i've tried search app architecture design, found how android architecture looks like, not how android app should like. so what's opinion that? components of android application should communicate each other ensure best extensibility/encapsulation,...? there's no 1 answer question. oo design isn't android specific. i'd rule - if framework gives high level object (such service in case of android) fits use case, use it. if fin...

edit okay, rookie here please bear me. i'm trying ask following: is plausible python-syntax fan use 1 of these options while other team members "plain vanilla" version? matter of personal preference, or require converting other people using these technologies well? is possible convert between, say, jython , java or pyjamas , javascript? also, in general, advantages/disadvantages have people experienced using these in "real world"? i think states little more i'm looking for. input uses these technologies in industry helpful. thanks in advance insights. you talking 2 different things. first, jython , ironpython python implementations can embed in java or c# application provide scripting capability. reduces amount of code have write overall. or can @ them way glue , leverage existing collection of class libraries. @ it, these things , lots of people use them. but pyjamas else entirely. complicates web stack , makes harder pass pro...

i've written program highlights numbers , copies them. able basic math copied text, such multiplication or addition, can't figure out how assign clipboard data variable. basically, able copy number, assign variable "a", repeat variable "b" , multiply 2 together. have figured out how select , copy number part isn't issue. appreciated, different approach have tried. here latest attempt @ problem: handle clip0; openclipboard(null); emptyclipboard(); clip0 = getclipboarddata(cf_text); variable = (char)clip0; closeclipboard(); where "variable" variable. whenever run program , tell output "variable", returns value of 0. another attempt made this: handle clip1; if (openclipboard(null)) clip1 = getclipboarddata(cf_text); variable = (char)clip1; closeclipboard(); but "variable" take on value of -8 the text content of clipboard c-string pointed c. if(openc...
