i have php file returns string this ["item1","item2","item3","item4"] i need create combobox extjs. options must items 4 options. how if php link items.php . make things clear need combobox displayfield , valuefield have same values, item1 displayfield , valuefield . in advance! p.s. string not json formatted, guess it's array store. firstly, think have modify php script returns string @ least [["item1"],["item2"],["item3"],["item4"]] . otherwise have create own extjs reader or override ext.data.reader.array.read method. secondly, store should this: var store = ext.create('ext.data.store', { fields: ['item'], proxy: { type: 'ajax', url: '/items.php', reader: { type: 'array' } } } thirdly, combo config should this: ext.create('ext.form.combobox', { store: store, displayfield: 'item', v

i understand using as operator cast object, on explicit cast, more desirable due fact if cast fails, reference variable goes null instead of throwing exception. however, lets check see type of class object is, that's inside of list, prior using as operator, so, drawablegamecomponent drawcomponent; foreach (component in components) { if (component drawablegamecomponent) { drawcomponent = component drawablegamecomponent; // drawcomponent } } does using as operator lose benefits checking is operator first? doing following cast good, because first check class type using is before attempting cast? if (component drawablegamecomponent) { ((drawablegamecomponent)componet).visible = true; } i'm wondering if there underlying piece i'm missing, or if comes down matter of taste pattern use. latter pattern create garbage through explicit cast? thanks in advance! better (saves 1 "cast" - compare generated il)

i've started designing 'schema' of distributed store database. i keep having mental debates on how denormalize. understand how it, , why increase performance if denormalization matches queries minimize gathering data multiple places... ...but, it's said pre-mature optimization bad. advantages of design relational, references instead of duplicate data embedded clear: elegant, flexible, no worries keeping duplicate data consistent, etc. so wondering whether it's reasonable strategy design schema in relational way, using application layer gather data necessary, , change later if needed. if traffic becomes issue, on technology can scale horizontally design changes (isolation, denormalization). seems best choice among: start rdbms, move distributed store if needed start distributed store, full denormalized design (scale-ready) start distributed store relational design, denormalize + isolate if needed thoughts? thanks i'd go option 2,

i noticed breaking (for me using ognl) change in 2.9.0-1: i find that, in 2.9, methods declared in trait become volatile when mixed in class: example in 2.9.0-1 import java.lang.reflect.modifier trait supertrait { def getknoll = "kanutten" } class klasswithknoll extends supertrait { def getknall = "mars" } val qsc = classof[klasswithknoll] val knollgetter = qsc.getdeclaredmethod("getknoll") println("isvolatile: " + modifier.isvolatile(knollgetter.getmodifiers())) this prints out isvolatile: true but in 2.8.1: it prints out isvolatile: false this breaking change me ognl refuses execute volatile (why don't know) in expressions. so - question is; why change made? there's no such thing volatile method. seeing 0x0040 flag set, acc_volatile fields, acc_bridge methods. since modifier.isvolatile method takes int, can't tell you're asking not meaningful.

i implement such design using floating css divs: --------------- |header | --------------- |col1| row1 | | |--------| | | row2 | --------------- | footer | --------------- i searched around found no easy way it. how achieve this? thanks. edit: want clarify problem. want have 2 rows of images next menu bar on left. trying use float:left image layout. edit2: solved problem myslef using display:inline-block image elements instead of float:left. i start container has width of page. example, we'll width:950px. of weird widths caused because of borders, if removed them, the widths more regular numbers 400, 950, 350 etc. here live example: http://jsfiddle.net/edgbp/embedded/result/ <html> <head> <style type="text/css"> #maincontent { width:950px; height:100%; margin:0 auto; } #header { width:946px; height:150px; border:#000 solid; border-width:2px 2px 1px 2px; } #leftcolumn { widt

code: import ast globalsdict = {} fast = ast.functiondef( name="foo", args=ast.arguments(args=[], vararg=none, kwarg=none, defaults=[]), body=[], decorator_list=[]) exprast = ast.interactive(body=[fast]) ast.fix_missing_locations(exprast) compiled = compile(exprast, "<foo>", "single") eval(compiled, globalsdict, globalsdict) print globalsdict["foo"] with both cpython , pypy, getting segmentation fault. why? cpython bug report pypy bug report abstract syntax trees documentation i guess function definition must not have empty body. tested code adding no-op statement function body: fast = ast.functiondef( # ... body=[ast.pass()], # ... and segmentation fault gone; output is: <function foo @ 0x022db3f0> if correct, bug in ast module, since should check empty body.

i have sample program nothing hello world. open ie , go development environement , access silverlight, loads xap first time , if close ie , open again, xap not downloaded. since there no changes expect not download. after deploying in qa environement, open ie first time, load xap expected. now close ie , open again, expect not download xap does download xap again. if refresh on page not download xap. happens on fresh ie open in our qa environment. all above tests done on same box same ie setting. there no client side ie cache issue. did check date , time on servers see if there difference specified in silverlight xap gets downloaded everytime link , our servers in same date , time. does 1 know how prevent iis not download everytime? the default settings in ie mean fresh instance of ie always attempt fetch each unique url when first encountered. ie if cache headers sent resource last time fetched indicate resource still fresh. however ie send if-modified-since

i have set reportsmanager page 2 accounts have access using "folder settings" security role assignment page. added 2 accounts, lets call them "user" , "reportuser". "user" content manager role. "reportuser" browser role. likewise under "site settings" set "user" system administrator , "reportsuser" system user. when launch reportsmanager page locally while logged in "user" can access site correctly expect. when try access reportsmanager while logged in "reportsuser" tells me rsaccessdenied. "user" member of administrators. "reportsuser" normal user. even though "reportsuser" set site browser , site settings config of system user had still launch ie administrator (or disable uac) reportsuser able view page without error. if turned off uac wasn't issue have leave uac on. if hit reports manager page xp acts normal. stupid uac.

i have check box in winforms, when checked set string e.g.: string checkbox = true edit: or better example: bool checkbox = true; so when method run lookup string , dependent on it's value perform a submethod... so question how set string on checkbox when clicked, have checked actions list , closest "checkchanged", won't work. why checkchanged not work? bool checkbox = false; private void checkbox1_checkedchanged(object sender, eventargs e) { if (checkbox1.checked) { checkbox = true; } } or use checkbox1.checked in subroutine.

i reading answer question , solve problem single field, how watch fields (input, select, radio, etc...) on form? this have (i'm using delegate, form injects page dynamically): $('#preferencesbody').delegate('input[type="radio"], select', 'change', function() { var key = $(this).attr('data-key'); var value = $(this).val(); // how old value, , compare current value, if different, call saveuserpreferences? preferences.saveuserpreferences(key, value); }); thanks. $('#formid :input') will select input fields (including textarea's , buttons) on form id=formid so function this.. $('#preferencesbody').delegate(':input', 'change', function() { var key = $(this).attr('data-key'); var value = $(this).val(); preferences.saveuserpreferences(key, value); });

how manage, morbo-server called here background-process shutdown/killed automatically if close firefox-window or if stop script in way? #!/bin/bash morbo mojolicious_lite.pl & firefox -new-window http://localhost:3000/ ok, let's solve one. #!/bin/bash morbo mojolicious_lite.pl & p=$! trap "kill $p" int # maybe want exit here too? firefox -new-window http://localhost:3000/ wait this 1 should work... when firefox exits shell wait remaining jobs (morbo) can interrupted ctrl-c - in case trap kills them. you can test visually (i.e. seeing gets executed) with bash -x run.sh assuming script called run.sh ;)

alright, i'm going try explain best possible: i have 2 models employer.rb class employer < activerecord::base has_many :listings end listing.rb class listing < activerecord::base belongs_to :employer end employers login through employers_controller , listings created through listings_controller i'm having trouble getting id employer table being inserted employer_id column in each individual created listing. hope makes sense. if has advice, appreciated. have feeling because i'm doing outside of employer_controller, not sure. thanks! 1) if not dealing nested resource then when render new action of listing controller, know employer (@employer) want create listing. so render hidden field employer_id using hidden_field or hidden_field_tag hidden_field_tag 'employer_id', @employer.id() 2) if dealing nested resource , route looks /employers/:employer_id/listings/new / (get) && /employers/:employer_id/listings

i have strange issue contentinsent . implementing "pull & release" refresh on uitableview , works fine, in cases display "loading" status without user interaction. thought use contentinset in following way: scrollview.contentinset = uiedgeinsetsmake(60.0f, 0.0f, 0.0f, 0.0f); everything works fine 1 or 2 cells displayed - out of 3 possible on view. once number of cells grows banner @ top not displayed, @ same time manually scrolling works fine. have move scroll besides moving content? ok, found answer playing bit different values. turnes out in case described above besides setting contentinset have setup contentoffset . in case following code worked: scrollview.contentinset = uiedgeinsetsmake(60.0f, 0.0f, 0.0f, 0.0f); scrollview.contentoffset = cgpointmake(0.0f, -60.0f);

when create standard class do: $test = null; $test->id = 1; $test->name = 'name'; however in strict-mode error. so correct way of doing is: $test = new stdclass(); $test->id = 1; $test->name = 'name'; so wondering: is big no-no do: $test = null; want? what gain conforming strict standards? make sure code keep on working in future versions? better backwards compatible? matter of best practice? else? edit typo is big no-no do: $test = null; want? yes. it's allowed because php loose, turning on strict mode gives god's-honest truth. what gain conforming strict standards? make sure code keep on working in future versions? better backwards compatible? matter of best practice? yes. something else? it's right .

probably newbie question but, ive been reading around , have found difficulty in understanding creation , storage of passwords. i've read md5/hash passwords best ways store them in database. however, how go creating passwords in first place? so have login page user bob, , password bob123 - how 1. bobs password database begin (hashed) 2. how retrive , confirm hashed password? thanks first off md5 isn't greatest hashing method use try sha256 or sha512 that said lets use hash('sha256') instead of md5() represent hashing part of process. when first create username , password hash raw password salt (some random characters added each password make them longer/stronger). might coming in create user form: $escapedname = mysql_real_escape_string($_post['name']); # use whatever escaping function db requires important. $escapedpw = mysql_real_escape_string($_post['password']); # generate random salt use account $salt = bin2hex(mcrypt_c
