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 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.

suppose have following scenario: 2 users both signal ready play, rails app receives , starts game one of 2 users issue "forfeit" via ajax (im assuming it's not possible prevent that, amirite?) by time other user polls figure out whether game has started, game has ended , scores updated that user confused i'm not quite sure here. can give me ideas? alright, figured out did wrong. (cant self answer yet because rep low) when user polls figure out whether his/her game has started, , receive moves , etc, check "game in progress" , "user = user polling" attributes figure out respond. that's wrong, because ends, logic fails find relevant game retrieve data , give user. what i'm think of right is, add "end game has been polled" attribute game object (well, playing objects through relationships) if game ended has not been polled, user receive once respond confirm. game not polled again. the flag indicating gam...

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 ;)

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 .
