so i'd able allow other applications residing on same machine call java application. the call either launch app if not running , invoke method or invoke method. ideally communication should language independent calling application written in language. has done before , can suggest things explore/avoid? thanks i'd use tcp , make application daemon. if want application easy other platforms integrate with, should use text based protocol define suit needs. and avoid xml if don't need transport complex structures. (i'd go json if need more complex data transfer). if new socket programming, might help: http://download.oracle.com/javase/tutorial/networking/sockets/

i had extract 2nd parameter (array) onclick attribute on image, jquery returned function onclick , not string value expected. had use native method. quick search says may work browsers ff, not ie. use chrome. <img src="path/pic.png" onclick="funcname(123456,[12,34,56,78,890]);" /> i thought work, it not : var div = $('div_id'); var onclick_string = $(div).find('img').eq(0).attr('onclick'); var onclick_part = $(onclick_string).match(/funcname\([0-9]+,(\[.*\])/)[1]; // reason \d doesnt work (digit) this works var div = $('div_id'); var onclick_string = $(div).find('img')[0].getattributenode('onclick').value; var onclick_part = $(onclick_string).match(/funcname\([0-9]+,(\[.*\])/)[1]; // reason \d doesnt work (digit) is there way of getting 2nd parameter ? why not store in data property? <img src="path/pic.png" onclick="funcname(123456);" data-mydata='12,34,56,7

suppose define grid in xaml like: <grid x:name="layoutroot" background="white"> <grid.rowdefinitions> <rowdefinition height="auto" /> <rowdefinition height="*"/> </grid.rowdefinitions> <grid.columndefinitions> <columndefinition width="auto"/> <columndefinition width="*"/> </grid.columndefinitions> </grid> then want add child control grid in column=0, row = 1 in code behind. how implement it? quite late response here go: grid.setrow(yourcontrol, 1); grid.setcolumn(yourcontrol, 1); grid.setrow(othercontrol, 0); grid.setcolumn(othercontrol, 0); the first parameter control you've added grid. second parameter column/row position want add to.

most applications (and libraries) using opengl on linux load libgl.so @ runtime using dlopen api, instead of dynamically linking against it. why this? the reason can imagine it's because graphic driver vendor provides different libgl , , 2 different libgl abi incompatible. (well, hum, why should abi incompatible? , if are, why loading them via dlopen fix issue?) anyway, supposing there's reason doing that, i'd well. have link opensource c/c++ code loads opengl functions via dlopen , can include project without needing many tweaks? there 2 main reasons people this: you can give sensible error systems don't have opengl vendors offer many different extensions , sane way support multiple sets of extensions without different binaries per vendor use dlsym check them. glew offers nice way of doing though.

i'm trying override default resourcebundlelocator in hibernate validation 4.1. far works perfectly, examples of usage include java code instantiate validationfactory. when using web application spring hibernate validation automatically configured (only suitable hibernate validation *.jar file should exist , automatically used). how can substitute resourcebundlelocator in scenario? not see way of specyfing custom resourcebundlelocator in properties or applicationcontext.xml file. the magic method required job localvalidatorfactorybean#setvalidationmessagesource(messagesource messagesource) . first of all, contract of method:- specify custom spring messagesource resolving validation messages, instead of relying on jsr-303's default "validationmessages.properties" bundle in classpath. may refer spring context's shared "messagesource" bean, or special messagesource setup validation purposes only.

in question asked, raised concern spring framework not type safe. true, or fixed, , can give example means exactly? first of all, "type-safe" mean dependency injection framework. can think of can bean context specifying type, , not bean name. spring 3 allows this. otherwise, type-safety means when can define dependencies type. , can in versions of spring. another thing compile-time safety. spring pre-3.0 when had differentiate between 2 beans share same interface (or supertype) using string-based name. in spring 3.0 can use annotation-based qualifiers (using javax.inject.qualifier ), compile-time safer well. another thing mention use of generics. can have, example @inject list<myservice> in spring.

can explain this? >>> x=x[0]=[0] >>> x [[...]] >>> x x[0] true >>> x[0][0][0][0][0][0][0] [[...]] >>> x in x true what [...]? that's python telling you have circular reference; it's smart enough not enter infinite loop trying print out.

i need write application (among other things) renders 2d animated images, let's suppose it's videogame. figured out videogame-like images can have quite complex structure depends little on program logic, on image itself: it can have several animations (one each state object draw can on) to pass state there acyclic animation too. each animation can made of several frames, each of has got duration. and way store images on disk can complex: the above properties of image, of states , of frames should stored on data file bound image, not hardcoded in program source. the different frames put in same image file, or on different layers of image file, or on different image files. background pixels indicated via separated bitmask or using specific color. and guess actual videogames need lot more parameters don't (don't know, bitmask identify pixels replaced team color or whatever). this makes me think there must library of this. half hour on google didn&

in following function looking expression replace isintegral<t> . the intention when t integral type add 0.5f before static_cast implictly floors value (and obtain rounded value), when t fractional type add nothing, , static_cast can reduce precision. t interpolate( t const & prev, t const & next, float interpolation ) { float prevfloat = static_cast< float >( prev ); float nextfloat = static_cast< float >( next ); float result = prevfloat + ( (nextfloat-prevfloat) * interpolation ); return static_cast< t >( result + ( isintegral<t> ? 0.5f : 0.0f ); } use std::numeric_limits<t>::is_integer (it's in <limits> header).

i trying use django's generic views make user registration page. have following code in app's urls.py from django.conf.urls.defaults import * models import ticket urlpatterns = patterns('', (r'^new/$', 'django.views.generic.create_update.create_object', { 'model': user } ), ) now when go url following: templatedoesnotexist @ /new/ auth/user_form.html i have tried making template match keep getting message. advice? also, assumed make template me. put in template file when make it? edit: coming rails mixing templates , views. still stuck think need make function in view. like: def user_form: #stuff you need create template file using format <app_label>/<model_name>_form.html . place template template directory defined in template_dirs in settings file. in template file itself, need use context defined standard modelform. {{ form.name.label_tag }} {{ form.name }}

i have graph (implemented vector) of linkedlists , want connect linkedlists not share common elements. think way right takes o(n^3). have loop iterates through vector, nested loop inside iterates through vector (so can compare each list every other one), inside loop use recursion compare lists. before trying way, tried having while loop inside 2nd loop iterate through each list , use binary search see if 2nd list contains each element, think takes same amount of time or longer. here loop: public void addedges(){ for(int =0; < size()-1; i++){ for(int j = i+1; j < size(); j++){ if(compatible(get(i),get(j),1,1)){ get(i).linkto(get(j)); get(j).linkto(get(i)); } } } } and here recursion: public boolean compatible(row a, row b, int indexa, int indexb){ if(a.get(indexa).getend() == b.get(indexb).getend()){ return false; } else if(a.get(indexa).getend() == 0){ return true; } else if(a.get(indexa).getend() > b.get(indexb).geten

the query below works fine. following: update flag1 = '$uflag' if flag1 empty. update flag2 = '$uflag' if flag1 had value in , flag2 empty. update flag3 = '$uflag' if flag1 , flag2 have values in them , flag3 empty. how this? update submission set votes_up = $votes_up, flag1 = '$uflag' submissionid = $id if want keep query simple, determine sql utilize in php using conditions prior sql's execution.

i creating uisegmentedcontrol replacement works own custom images. because separators need different colors on both sides decided give middle item 2 borders. now display uisegmentedcontrol replacement, calculate available width 1 item (frame.size.width / numberofitems). create uibutton custom background image (the stretchable middle segment image). next thing position everything. because 1px separators need visible when select item, give every item 1px larger frame should have. next item overlaps 1px left. segmentrect = cgrectmake(indexofobject * (self.frame.size.width / numberofsegments), 0, (self.frame.size.width / numberofsegments) + 1, self.frame.size.height); using result nearly perfect custom uisegmentedcontrol (retina): now things pretty ok, changes when adding more/less segments. 300px wide control way, each segment gets 25px of space. if change number let's 13, shows up: notice different border between '3' , '4'. (easier spot on non-retina be

my first question on so! :) in advanced! i'm having problem jqgrid multiple selection functionality. can define single multiple selection key , above shift doesnt select more 1 row collection @ time. any clue on different grid plugin or work around functionality? also, jqgrid have option hide check boxes when multiselect active? welcome on stackoverflow.com! you can find here examples shows live how different settings of jqgrid having multiselect:true works. option documented . you can @ here code implement musliselect behavior standard. tell truth don't tested solution.to hide checkboxes can use $("#list").jqgrid('hidecol','cb'); because checkboxes placed in column name 'cb'. mostly jqgrid used paging feature, not many rows displayed @ once , not real problem select many rows. nevertheless agree keybord support not enough in jqgrid. other important functionality on other side rich, don't see alternative plugin

my question this: if have 2 heads (branches changes) in mercurial repository, , i'd rid of 1 of them, discard changes branch instead of merging them other, , can't strip out changesets have merge, how can command line client? if have 2 heads in mercurial repository, , use tortoisehg client, repository might this: then can rid of test2 head doing merge , discarding. first update head i'd keep ( test3 in case, in image above current parent of working folder). right-click , select "merge with...": and in dialog pops choose discard changes merge target (ie. branch i'd discard changes from): after merge has gone through, changes in test2 head has been discarded, , can commit. head has disappeared, changeset still part of history. my question this: how can same thing using command line client? can't find matching options hg merge command: hg merge [-p] [-f] [[-r] rev] merge working directory revision ... snipped text options:

i'm having problem initializing array of structs in c program. here's function gets initialized: void initializebpstructures() { satcountertable = (struct satcountertableentry *)malloc(sizeof(struct satcountertableentry) * counter_count); } counter_count integer global variable , satcountertable declared earlier in c source file static struct satcountertableentry* satcountertable; and if it's relevant satcountertable struct struct satcountertableentry { enum satcounter_state predict_state; md_addr_t tag; }; md_addr_t label unsigned int corresponding memory address the problem when try , compile, following error sim-safe.c:129: error: expected expression before ‘=’ token and array initialization in intitializebpstructures() on line 129. i'm not sure why line problem. ideas? edit: here's additional lines of code around function struct satcountertableentry { enum satcounter_state predict_state; md_addr_t tag; };

i'm binding user settings bunch of controls on winform dialog has ok/cancel buttons. while works great read in bindings in, commit binding changes if user clicks ok, , not if click cancel. there simplistic setting achieve rather managing reading , committing myself? right now, let's have textbox binds user setting called "country". has "united states" in , if user changes "bolivia", committed typed instead of when ok button pressed. to save settings, add in ok button event handler: properties.settings.default.save(); to reload settings: properties.settings.default.reload(); good luck!

let's have array this: array ( ['one'] => array ( ['wantedkey'] => 5 ['otherkey1'] => 6 ['otherkey2'] => 7 ) ['two'] => => array ( ['otherkey1'] => 5 ['otherkey2'] => 6 ['wantedkey'] => 7 ) ['three'] => => array ( ['otherkey1'] => 5 ['wantedkey'] => 6 ['otherkey2'] => 7 ) ) if apply sth array instances of 'wantedkey': function test_print($item, $key) { if ($key === 'wantedkey') { print $item; } } array_walk_recursive($myarray, 'test_print'); but array_walk_recursive doesn't tell me (afaik) in array....is there way track positi

for xmpp interface stack overflow chat , taking html of chat messages , converting valid xml , , setting html child element of xmpp message object. in mac os x jabber client working great! meant when users in chat posted oneboxed image, image show in xmpp client (adium os x): however updated adium latest version , apparently they considered doing security hole , against xmpp specs, , changed behavior . reasoning xmpp should not reveal ip address, , fetch image on http reveal ip address. so chats imageless on xmpp. how can make images work on xmpp? should xmpp component download images , embed them <message> stanzas? can images proxied through xmpp server? or impossibility? adium, ichat , pidgin support xep-0231 , allows send provide binary data, including images purpose. basically, allows specify unique identifier source image, , other client can decide if wants request data in <iq> request. i've been working in python's twisted , meeting fr

what mean when have list parameter method? public static void killzombies(this list<zombie> zombiestokill, int numberofbullets) { ... } that mean method extension method : the code calling method might little confusing: var zombies = new list<zombie>(); zombies.killzombies(15); in reality, kind of syntactic sugar equivalent to: public static void killzombies(list<zombie> zombiestokill, int numberofbullets) { // code here } with calling code looking like: var zombies = new list<zombie>(); killzombies(zombies, 15);
