anyone can detail pros , cons pass data 1 class using event mechanism? when best time use event pass data? let's take example. have system 20 people subscribed weather station changes in weather. want weather station keep track of people , services subscribed? in opinion weather station should not know people or services waiting weather changes. weather station should dispatch event, , whoever listening notified :-) so point is, use events notify observers action or state change occurred in object. observers can difference type of objects since don't have know them. if listens object, takes care of it. if 1 one relation , object waiting happen of same type, wouldn't need event case. events great decouple systems, seen in example above weather station. weather station can run on own without knowing services or users listening it.

i have page has multiple forms. i'm using mootools sliding tabs each of buttons on menu slide along next form. there 3 forms technically on same html page. see example of technique @ http://creativepony.com/archive/demos/sliding-tabs/ my problem when user presses tab key , tabs through last field want tab order goes first field. user not accidentally tab next form. user end looping around same form fields. user reach next form use menu don't want them able tab next form. i aware of setting tab order 'tabindex' doesn't me make user return first field of form. any ideas how achieve javascript? i making fields in forms aren't visible disabled , browser knows skip them, regardless of navigation mechanism (think accessibility aids).

this basic database design question. want table (or multiple tables) defining relationships between customers. want primarycustomer can linked multiple secondarycustomers, , can have many secondarycustomers same relationship. primarycustomerid relationshipid secondarycustomerid 1) if primary key {primarycustomerid} can have 1 linked customer of kind. 2) if primary key {primarycustomerid, relationshipid} , can have 1 linked customer each relationship type. 3) if primary key {primarycustomerid, relationshipid, secondarycustomerid} , can have whatever like, having columns primary key seems wrong. what's right way set things up? number 3 right way go data model. linking tables have columns in join link other tables.

i working on widget fetching , displaying data. refresh rate custom. what do, fetch data when widget displayed (when launcher on top). is there way check if launcher displayed? there's no way of doing this, unless of course homescreen has api requesting information. best bet listening screen turn ons/turnoffs. but so, pick conservative refresh rate , let users modify it.

my project's output path set "bin\debug\" i'm building through vs2010 , builds ..\..\build\bin\x86\debug (and not bin\debug). can't find other settings in .sln or .csproj might affect this. ideas? turns out have (plugin?) msbuild looks before.targets file in parent directory , overwriting outdir based on that.

i creating outlook 2007 add-in using vsto. need store information (entered user) each email. first thought create small "database" references each email necessary. can't seem find accessible identifier each email purpose. there id or other unique field available each mail message item can use? c# or vb.net code fine. can easy points you! thanks in advance! the mail item has number of properties, including entryid property . can add custom properties .

i'm trying make "dark mode" app, , i'd in easy way. there way apply filter or create view on other views appear inverted - "accessibility" on ios 3.2+? know core image filters don't work on iphone, that's not big deal me - long there's way apply different sort of filter. is feasible on iphone? how apple it? it sounds you're thinking of placing semi-transparent view filled dark color on entire user interface. if that's case, should read forwarding touch events discussion of issues involved. another way change set of colors , images use draw views. both these schemes easier , work better if you're dealing custom views. if you're using overlay, document linked above explains standard ui elements don't take kindly event forwarding. if change colors, well... depending on ui elements you're using, may or may not possible substitute own images , colors.

when wrote these commands out = ones(size(ben)) imshow(out) the output white picture expect dark picture because rgb values 1,1,1. when give 255,255,255 gives white picture. isn't dilemma ? try out = ones(size(ben), 'uint8'); ones() default creates array of doubles. when imshow() gets array of doubles assumes pixel values range between 0 , 1, , assigns white color greater 1. however, if pass array of uint8 imshow() assume range between 0 , 255. you can try using imagesc(); instead of imshow() , may need colormap gray after wards grayscale image. another alternative rescale image before display: imshow(out / max(out(:)));

this apparently interview question (found in collection of interview questions), if it's not it's pretty cool. we told efficiently on complexity measures. thought of creating hashmap maps words frequency. o(n) in time , space complexity, since there may lots of words cannot assume can store in memory. i must add nothing in question says words cannot stored in memory, if case? if that's not case, question not seem challenging. optimizing own time: sort file | uniq -c | sort -nr | head -10 possibly followed awk '{print $2}' eliminate counts.

hi: using hibernate3.6,i meet problem when querying. take hql exmaple: string hql="select count(distinct ip),sum(bytes) entity en .... query q=session.createquery(hql); list<?> list=q.list(); now can retrive columen properties list following way: string[] properties={"count","sum"}; (object obj : list) { map<string, object> m = new hashmap<string, object>(); object[] props = (object[]) obj; if(properties.length!=props.length) throw .... (int = 0; < props.length; i++) { m.put(properties[i], props[i]); } } now,my problem that,when hql result no set,the count 0,but sum null. want 0 also. of course,i can converting explicitly if know column name , type(they count,sum in above example) of result table db,but did not know. that's say,i can not use this: if(props[i]=null) props[i]=0; m.put(properties[i], props[i]); since type of props[

are there frameworks flash (as3) optimised outputing iphone using flash packager iphone ? i have used "packager iphone" of flash apps , games, , work ok. there things need changing. there guidelines creating content , using packager. can see guidelines here . are there application or game frameworks out there yet, take sort of optimisation account? i not think exists far. project suspended while (when apple not allowing use c++/objective c devices) - it's life, expect come.

let's have 3 classes. 1 being parent , 2 being "childs". however, i'm not using class - extends - : class root { function root(){ $this->son = new son(); $this->daughter = new daughter(); } } class son { ... } class daughter { ... } how call function of son function of daughter ? in other words, how reference class root son/daughter call functions of each other, each other? a classic case of dependency injection. class root { function root() { $this->son = new son($this); $this->daughter = new daughter($this); } } class son { function __construct($parent) { $this->parent = $parent; } function foo() { $this->parent->daughter->bar(); } } just careful not create rigid dependencies between classes shouldn't have them. inheritance may better way go. alternatives include registry pattern , factory patterns.

i've finished implementing modal dialog login popup asp.net website. experience similar digg.com. when log in, fancy popup modal dialog (provided jquery tools overlay control ). dialog ascx file in master page, it's available globally. uses pagemethod validate current user. if validation succeeds, call window.location.reload(); in pagemethod's success callback. this works great when logging in on page doesn't require authentication, when non-auth users trying navigate page requires auth? is possible modify web.config file instead of redirecting signin.aspx page non-authenticated users invoke modal dialog instead? let's non-authenticated user on default.aspx doesn't require auth. wants navigate "add.aspx" does require auth. what's best way handle modal dialog popup? if have use dedicated page, guess i'll have signin.aspx page invokes dialog when loads , if authentication succeeds, it'll use javascript redirect destinatio

so have rather large opengl program going, , checking normal memory leaks (those new , delete) rather trivial -- run on valgrind. but best way check potential opengl leaks? there opengl utility that'll tell how many resources (e.g framebuffers) being used @ time, or such? or way attach counter every glgenblah , gldeleteblah pairs? glintercept check textures haven't been freed, perhaps checks framebuffers, if not, maybe modified it.

i browsed through mark probst's diploma thesis , stumpled on following code: typedef void* cont(void); (;;) { cp = (cont*)(*cp)(); } i'm pretty sure cast should read (cont) , not (cont*) , because explains: the function wishing proper tail call returns the address of function called and cont pointer-to-function type. let's change line to: cp = (cont)(*cp)(); now wondering, how can rid of cast? can cont defined returns cont ? how typedef cont like? need helper type achieve this? impossible? no, typedef void* cont(void); cont defines function type returning void * . think confusing typedef void (*cont)(void); or typedef void *(*cont)(void); . i don't believe it's possible eliminate need cast in scenario i'm open convinced otherwise.

i setting variable in makefile this: somevar = foo this makefile later includes other makefile in actual building of programs takes place: include generic/makefile.common so no build targets defined in first makefile , it's setting variables used common generic makefile actual package building. now know should careful when using foo , remind myself of this, want print warning message whenever makefile used setup make process. problem cannot insert echo command after variable definition, because not yet building there. is there solution (more elegant adding fake target message printed destroy separation of setting variables , building)? somevar = foo $(warning careful foo)

i making several jquery xml requests , need called on document ready , others need called function call? noticing lot of code duplicates because wrapping xml requests in function. here example. $.ajax({ type: "get", url: "english.xml", datatype: "xml", success: function searchstr(xml, val){ val = val.tolowercase(); $(xml).find("a").each(function(){ $(this).find('b').each(function(){ $(this).find('c').each(function(){ $(this).find('d').each(function(){ //calculations }); $(this).find('d2').each(function(){ //calculations }); }); }); }); } }); this first 1 being called on document ready.... function searchforstring(val){ $.ajax({ type: "get", url: "english.xml", datatype: "xml", succe

i know exact advantage gained in doing android xml parsing using dom parser , sax parser? dom parser advantageous sax parser or vice-versa? please clarify. thanks, sen hi sax parsing best 1 implement dom, see difference between these 2 in following: dom the nodes in form of tree structure memory: occupies more memory, dom preffered in case of small xml documents slower @ runtime stored objects programmatically easy implement ease of navigation , use. sax sequence of events it doesn't use memory preferred large documents. faster @ runtime, because of above mentioned point. objects created. need write code creating objects in sax backward navigation not possible sequentially processes document

i'm using qt 4.7.0 (32 bit) on windows 7 ultimate (32 bit) machine. i've been using qt version 4.0 or 4.2 , i've used 4.x.y releases. recently, qt 4.7 i've faced trouble. i've written multithreaded application in older version of qt. i've forgotten version last version compiled , ran 4.5.x or 4.6.x. threaded part doesn't seem working correctly in 4.7, or misunderstood something. here problem: the main thread starts thinker thread. following run() function of thinker thread: void thinkerthread::run() { _threads_running = nsubthinkers; // ... _sub_thinker[0].start(); // ... _sub_thinker[1].start(); exec(); } the _sub_thinker 's finished() signal connected thinkerthread::subthinkerfinished() slot _sub_thinker s. when _sub_thinker s finish, thinkerthread::subthinkerfinished() calls quit() . there place quit() called: void thinkerthread::trykill() { (int = 0; < nsubthinkers; i++) _sub_

i have basic query access using sql, want bring null if nothing returned. for example if state where cust_id = "win" if there no "win" query bring null. i had thought use isnull have not managed work. thanks in advance zane to null if condition fails require either case statement around column definition or left outer join instead of clause. iif(cust_id = "win", "win", null) or left outer join tablename on tablename.cust_id = "win" should work - don't have access available check.

i looking simplify of code implementing pretty simple schema , discovered indexeddb spec isn't yet finalized. the schema used present table user filtering mechanism , allow user add/edit rows of table. doesn't need stay persisted client (but make less traffic when available). feel confident use implementation done in js , gain benefits of native implementation when exists (presumably increased query speed , local storage). i aware of http://code.google.com/p/indexeddb/ under requirement in such way nothing needs installed. have gone mad or there this? indexeddb not implemented in major browser atm. think firefox 4 may testing -- http://hacks.mozilla.org/2010/06/comparing-indexeddb-and-webdatabase/ edit: didn't read -- want pure js implementation; sorry.

i've made new warning settings in eclipse. these new settings i'm facing strange warning. after reading got know couldn't find way remove it. here problem sample code public class test { private string teststring; public void performaction() { new thread( new runnable() { @override public void run() { teststring = "initialize"; // ** } }); } } the line * * gives me warning in eclipse read access enclosing field test.teststring emulated synthetic accessor method. increasing visibility improve performance. problem is, don't want change access modifier of teststring . also, don't want create getter it. what change should done? more descriptive example public class synthetic { private jbutton testbutton; public synthetic() { testbutton = new jbutton("run"); testbutton.addactionlistener(new actionlistener() {

the opposite of list flattening. given list , length n return list of sub lists of length n. def sublist(lst, n): sub=[] ; result=[] in lst: sub+=[i] if len(sub)==n: result+=[sub] ; sub=[] if sub: result+=[sub] return result an example: if list is: [1,2,3,4,5,6,7,8] and n is: 3 return: [[1, 2, 3], [4, 5, 6], [7, 8]] is there more eloquent / concise way? an aside, preferred when appending lists lists (in context above): list1+=[list2] or: list1.append(list2) given (according summerfeild's 'programming in python 3') same? thanks. such list of lists constructed using list comprehension : in [17]: seq=[1,2,3,4,5,6,7,8] in [18]: [seq[i:i+3] in range(0,len(seq),3)] out[18]: [[1, 2, 3], [4, 5, 6], [7, 8]] there grouper idiom : in [19]: import itertools in [20]: list(itertools.izip_longest(*[iter(seq)]*3)) out[20]: [(1, 2, 3), (4, 5, 6), (7, 8, none)] but note missing elements filled value none. iz

i'm putting wcf service handles large search (currently 50-60 parameters, more added in future). handle this, have search object criteria passed service in message object. while search parameters must available, case 2-3 of parameters receive user input , others null. mind, doesn't make sense pass entire object around through every method if few fields used. i'm looking technique extract fields used values, can validated , passed data layer execute search. few ways accomplish can think of include: use reflection loop through properties, , add non-null properties dictionary<string, object> . problem comes mind here lose type of search parameter, means data layer search function 1 giant case statement hard-coded cast values each potential field. seems overkill , creating way tight of coupling. create searchvalue class name, value, , system.type properties, , use reflection build list<searchvalue> . still results in big case check in search, rather property

i using xstream de/serialize objects json. i want serialize java.util.properties want serialized in javascript object literal. i.e. properties p = new properties(); p.setproperty("a", "b"); p.setproperty("x", "y"); should converted to: {a: 'b', x: 'y'} it not easy xstream, because xstream first marshals properties object intermediary xml before converting xml json , getting xml right hard. it far easier loop on properties , build json string directly. example, this: stringbuilder builder = new stringbuilder() ; builder.append('{'); enumeration keys = props.keys(); while (keys.hasmoreelements()) { string key = (string)keys.nextelement(); string value = (string)props.get(key); builder.append('"').append(key).append('"'); builder.append(':'); builder.append('"').append(value).append('"').append(','); } builder.

i'm using simplemodal (great library eric martin) create "wizard" users enter data. i'm making wizard work replacing contents of modal's div... ie: when modal displayed move contents of page1 modaldiv. when user clicks next, move contents of modaldiv page1 , move contents of page2 modaldiv. this works great, problem have having i'm using datepicker on page2. reading simplemodal documentation initializing datepicker in "onshow" callback... works great if datepicker on page1, not work if datepicker on page 2. how re-initialize datepicker when load page 2? well crap.. right when finished typing had idea solution, , worked (and it's better). i put page1 div , page2 div in modal div , hide/show page1 div , page2 div instead of moving contents around... kiss principle... gotta love it...

i'm using vs 2010 , playing around ability create, load, , save settings. read http://www.codeproject.com/kb/cs/usersettings.aspx default value field must given. possible set default value of string-type setting applications running directory? if not possible, hack @ give default value of "." , check @ run-time, changing program's current directory if needed, i'm open suggestions less hacky. go "hack" , detect when need use assigned value or else. settings dumb containers , know nothing app itself.

what best way create tutorial or screens can viewed in iphone app on launch? i'm debating between using 2 paradigms: edit screenshot of app image editing program add static text. interaction tapping or scrolling through tips. involves creating custom uiviewcontroller advance next screen. create custom iphone uicontrol on top of app user interface can tapped advance next tutorial tip. application transition between modes , active, rather static. involves adding hooks app's custom viewcontroller's handle "tutorialuicontrol" objects. here's screenshots of application need make screen ui for, it's application creates artwork. more app information screenshot 1: view mode allows viewers scroll through image list, uiimagepicker, custom image collections. screenshot 2: action mode - allows viewers select images save "my saved" album active art generation album "my evolution" or evolve images using sexual/asexual image reprodu

i trying make ajax call passing named parameters: $this->js->link('save',array( 'controller' => 'screens', 'action' => 'create') + $this->params['named'], array( 'update' => '#results')); however named parameters passed in above call incorrect (though correct when passed without ajax): example results: without ajax: http://paste.ubuntu.com/546338/ with ajax: http://paste.ubuntu.com/546337/ escaping ajax url might help, how can (or other way) ? p.s. : problem persists js helper, if use ajax helper data passes correctly. however, ajax helper depreciated , not recommended. what leo means this: $this->js->link('save', array('url'=>array('controller'=>'blah', 'action'=>'foo', $this->params['named']), 'update'=>'div&#

i figured out in order turn [some name] [some_name] need use following expression: s/\(\[[^ ]*\) /\1_/ i.e. create backreference capture starts literal '[' contains number of non space characters, followed space, replaced non space characters followed underscore. don't know yet though how alter expression works underscores within braces e.g. [a few words] [a_few_words]. i sense i'm close, missing chunk of knowledge unlock key making thing work infinite number of times within constraints of first set of []s contained in line (of sql server ddl in case). any suggestions gratefully received.... there 2 parts trickery needed: stop replacing when reach close square bracket (but repeatedly on line): s/\(\[[^] ]*\) /\1_/g this matches open square bracket, followed 0 or more characters neither blank nor close square bracket. global suffix means pattern applied sequences starting open square bracket followed blank or close square bracket on line. no

ngen + appdomain problem here. i'm working on application changes revolve around making native images load correctly prevent awful jit time in our .net application. parts easy, assemblies have load in appdomains (which our app has use variety of reasons) load native image first time, , on subsequent loads (in new appdomain) image rejected , jit occurs. i know domain-neutral loading, , have made use of of our assemblies makes sense, doing domain-neutral loading cancels out 1 of major reasons using appdomains in first place -- domain neutral images can never unloaded. put succinctly, need way have native images loading , assembly unloading. had hoped normal restriction wouldn't apply long unloaded first usage of native image before tried load again, resulted in rejection if trying load native image concurrently. this msdn article contains following quote: an alternative approach falling jit compilation load different copies of native image every appdomai
