when link directly uploaded file in zend framework based project differing results depending on if i'm working in local environment or remote environment. in both cases want link uploaded photo. generated url looks like: http://whateverserverweareon/projectfiles/project18/photos/aphoto.jpg on local machine clicking link show me photo, in remote machine gives me warning "invalid controller..." (as, while not have "projectfiles" controller, uploaded photos in projectfiles directory on path specified in sample url). so how link these uploaded photos? create controller can link them? can bypass controller altogether , link directly? there sort of custom route need create? should doing in different manner? suggestions? the exception means on remote mashine file not exists in specified location. standard rewrite rules in .htaccess file written if file exists (i.e. /projectfiles/project18/photos/aphoto.jpg) index.php file of zf not executed. should

i have several iboutlet , use them iboutletcollection : @interface iboutletcollectionviewcontroller : uiviewcontroller { iboutletcollection (uilabel) nsarray *multiplelabels; } @property (nonatomic , retain) iboutletcollection (uilabel) nsarray *multiplelabels; @end but when want use uilable properties compiler gives error : request member 'textcolor' in not structure or union i think it's because of nsarray ! there solution ? you can use key-value coding set property on each label instance in array: [multiplelabels setvalue:[uicolor redcolor] forkey:@"textcolor"]; "iboutletcollection(uilabel)" can omitted in ivar declaration long it's used in property declaration. another option call "makeobjectsperformselector:" on nsarray instance: [multiplelabels makeobjectsperformselector:@selector(settextcolor:) withobject:[uicolor redcolor]];

i have browser plugins insert iframe webpage. iframe inserted possible (using domcontentloaded ) contents of iframe render page. in firefox doesn't happen however. though iframe seems inserted early, content of page/images/etc load prior iframe's content. is there way around firefox behavior iframe content can load or first? not sure if matters here 2 methods equivalent results: method 1. inserting iframe on domcontentloaded method 2: nsiwebprogresslistener() onstatechange: function (abrowser, awebprogress, arequest, astateflags, astatus) { const state_start = components.interfaces.nsiwebprogresslistener.state_start; const state_stop = components.interfaces.nsiwebprogresslistener.state_stop; if (astateflags & state_stop) { //document undefined @ state_start try { //create iframe } catch (e) {} } return true; }, the listener domcontentloaded fires later 1 think on ff. problem solved using firefox's on

is there windowbuilder scala? i don't know of wysiwyg gui builder scala. don't need one. in fact, strictly speaking, scala doesn't have gui; uses underlying platform's gui (or guis). so, jvm port of scala uses awt, swing or swt , cli port of scala uses winforms or wpf. i've heard rumors of ports of scala ecmascript runtime , objective-c runtime, , presumable use html5 , quartz/cocoa, respectively. this means can use existing tools, expression blend wpf or matisse swing. note, however, @ least swing, there brilliant scala.swing library, contains embedded dsl building guis programmatically. not wysiwyg, it's not asking for, prefer it, because wymiwyg (what mean get), gui tools have used far, seems impossible achieve.

here problem , have created sortablecollection : observablecollection , added sort method (sort colors). when sort collection principal thread , works every thing fine , works when try sort customcollection using item in collection have expetion : (the calling thread cannot access object because different thread owns it). have looked in web , found several solution , one solution this type of solution put collection multithread insertion , removing moving operation. not custom sort. help, wpf classes have thread affinity. means changes objects must in same thread created. difficult create user interface api thread-safe, microsoft chose keep singlethreaded , force run-time checking make sure of it. that said, there few options have perform sort in background thread, , apply in ui thread. first option copy sortablecollection plain old list or array , perform sort in background. once background thread complete, use dispatcher execute code in ui thread. every ui elem

i have first class constructor takes parameter. public class first { first(object o){ o.tostring(); } } i have second class extends first one. public class second extends first { second(object o) { super(o); } } what want keep constructor of second class private in order to have possibility instantiate 1 instance of class (using singleton pattern, instance), compiler doesn't allow me that. if can't set constructor private here, can allow 1 instance of class created? you can make constructor of second private no problems. can't make constructor of first private, unless use nested classes. as example, works fine: class first { first(object o) { o.tostring(); } } class second extends first { private final static second instance = new second(new object()); private second(object o) { super(o); } public static second getinstance() { return instance; } }

in framework project have class represents tabs in content management system. in framewrok implementations desirable extend class defintions of tabs specific implementation. had though changing cmstabs class partial, this: namespace framework { /// <summary> /// class containing common cms tab names /// </summary> public static partial class cmstab { /// <summary> /// information tab /// </summary> public const string information = "information"; and creating class same name , namespace in assembly implements framework. however, when build framework assembly, cmstabs class appears no longer partial - it's members hidden in implementing assembly when add partial class that. when disassembled in reflector, this: public class cmstab {... is there need make retain partial status, assuming possible trying do. thanks. you can't have partial class span assemblies: all partial-type definitions meant parts

i'm implementing script engine in game wrote using c# "dynamic" feature. how system should work when script called, should register events listens for, return control application. when event script listening fired script should execute. 1 thing i'd implement in script engine have methods names automatically bind events. example, onturnstart() listener should automatically bind turnstart event. the scripts need execute existing methods , change variable values in classes; stuff player.takedamage() , player.hp = somevalue. scripts need wait start of players' turn , end of players' turn before being unloaded. the complicated part these scripts need able changed without making code changes game. (security aside) current plan have script changes automatically download when game starts ensure players using same version of scripts. however have 3 questions: 1) how register , unregister script event listeners? 2) can dynamic code listen events? 3) (how)

because sometimes, need friend. i can think of following tricks: read wrapper - readonlycollection . friend keeps pointer modifiable object, while else can access wrapper. write delegate - friend gives constructor of object reference delegate 1 of parameters, constructor fills address private method can used modify object. reflection - bad idea. included completeness. multiple assemblies - put friends in separate assembly , set modifier methods internal . expose modifiable object, add comments modifier methods "this infrastructure method - don't call it!" nested classes. add system.componentmodel.editorbrowsable(system.componentmodel. editorbrowsablestate.never) attribute member want friend access hide intellisense. implicit interface implementation - see comments. is list exhaustive? can sort these in order of decreasing performance? order of decreasing neatness? suggestions when use which? you can use internalsvisibleto attribute. for giv

is possible on android intercept outgoing text message , show "prompt" user before goes out? for example, can @ message, spell check, prompt user change spelling of before message sent? or, example, if create game around text messaging, , format of text needed changed little before going receiver (like adding comma). is possible? if so, start learn how this? is possible on android intercept outgoing text message , show "prompt" user before goes out? afaik, no. smsmanager -- on device uses send sms messages -- sends them directly. there no broadcast intents or plug-ins or intercept these messages. in part, imagine privacy reasons.

is there reason why there no implicit ordering lists in scala? val lists = list(list(2, 3, 1), list(2, 1, 3)) lists.sorted error: not find implicit value parameter ord: ordering[list[int]] edit yes, question why there no built-in ordering that's implicitly in scope. me, seems obvious second list should "less than" first list since items @ 0 equal , second list has lower item @ 1. wondering if maybe it's there's no answer when lists 2 different sizes. i think it's oversight. lexicographic ordering make sense on seqs. should add standard library.

the problem in middle of file fseek next exists bytes of length m want replace bytes of length n . simple write keep m-n bytes still there. if m > n , if m < n bytes ( n-m ) not willing change overwritten. i want replace known startpos endpos byte stream variable length bytes. best solution. -- edit -- though can done taking backup. there exists direct solution ? messy ? , kind of poor coding. o = fopen(original, 'r') b = fopen(backup, 'w') while(fpos(o) <= startpos){ buffer += fgetc(o) } fwrite(b, buffer) fwrite(b, replacementbytes) buffer = "" fseek(o, endpos) while(!feof(o)){ buffer += fgetc(o) } fwrite(b, buffer) //now copy backup original the robust solution re-write whole file, scratch. operating systems let overwrite bytes, not insert or remove them, file, accomplish that, have copy file, replacing target bytes during copy.

i need advice on best way implement scrollable playing field in simple game. field consists of multiple rows, 9 cells in each row. rows can dynamically added , removed during course of game. each cell has digit in it, , optionally several overlayed images, selection, selector over, crossed out, etc. (see pic below). user should able click on individual cells of row select/deselect/cross touched cells. @ point in game there can 0 3000 cells (0 333 rows). field should scroll , down smoothly. i thinking having listview each row being row on field. way add/remove rows dynamically during game. however, how should implement row: have 1 bitmap representing row, , when user touches -- coordinates of touch area, , find out cell affected, , act upon that. possible touch coordinates of row in listview? if not, should place 9 dummy image placeholders in each row, , act on user touching those? performance? or should have 1 huge bitmap / canvas representing entire field, place inside scrol

i've been playing wpf months now, , quite it. 1 of things don't why ms doesn't put little more effort in helping developers supplying basic controls, , need off chest :) for example, figure applications somewhere need let edit properties - configuration or whatever. used types in proprety-grid editor ? text numbers (byte, float/double, int, etc) colors ....etc. so why isn't there simple control edit numbers ? generic numericupdown control allows type in numbers (no text, no pasting invalid input) or spin them up/down according given rules (decimal, floating point, min/maxvalue) ? why isn't there generic colorpicker, people same user-experience in every application ? why isn't there standard implementation of searchtextbox, breadcrumb-control, or these other standard control types users have gotten accustomed last 10 years ? (..but @ least did have time implement a generic splashscreen - because knows greatly increases user-productivity....)

i'm studying way serialize part of data in database , deserialize in database b (a sort of save/restore between different installations) , i've had django natural keys avoid problems due duplicated ids. the issue should add custom manager , new method models. there way make django automatically generate natural keys looking @ unique=true or unique_togheter fields? please note answer has nothing django, give alternative think about. you didn't mention database, however, in sql server there binary_checksum() keyword can use give unique value data held in row. think of hash against fields in row. checksum method can used update database checking if local row checksum <> remote row checksum. this sql below update local database remote database. won't insert new rows, use insert ... id > @maxlocalid select delivery_item_id, binary_checksum(*) bc #di [remote.network.local].yourdatabase.dbo.delivery_item di select delivery_item_id, b

if have following private volatile collection<integer> ints; private void mymethod() { ( integer : ints ) { ... } } the ints collection never changed entire collection maybe replaced thread (so it's immutable collection). should copying ints variable locally before iterate it? i'm not sure if accessed multiple times. ie iterating collection, thread replaces collection, code continues iterating new collection. edit : this question relevant additional info on how foreach works internally. you don't have to. implicitly, code ints.iterator() anyway, , point on use iterator, on old collection.

i want quick&dirt load testing - results cached. commented out solr caches - still cached. can caching come 'field collapsing cache'. -- although don't see element in config file. ( system jumps 1gb 7 gb of ram when load test lots of queries ). can lucence cache? +-----------------------------------------------------+ want lower caches cache 100 or 1000 documents. ( right - when 50 000 unique queries solr use 7 gb of ram , fits in cache! ) any suggestions how proper stress test solr - small number of queries (some 100 0000 - not in millions testers have)? this not recommended praxis. results won't realistic. important tune cache settings! try hit solr queries build log files. i'm using fastbench kind of testing can use jmeter, bash script or sth. similar can lucence cache? yes field collapsing cache no, you'll need patch + config that
