i decompiled executable lost source code sometime ago. code wasn't same i've written has variables guess added automatically compiler. far, ok. when opened gui designer error: i don't understand why erros since variables declared , code compile fine. can't use gui designer. how fix this? when use designer design user interface, corresponding code put in separate file warning should not manually edit file, otherwise designer stop working. the decompiler doesn't take account designer @ all, you'll end code compiles , functions should - designer wouldn't able read properly. perhaps easiest solution create , design new form, , copy in code decompiled files afterwards (unless else has great idea not know of, of course).

i'm trying match string pattern, can have sub strings same pattern. here's example string: nicaragua [[note|note|congo member of iccrom 1999 , nicaragua 1971. both suspended iccrom general assembly in november 2013 having omitted pay contributions 6 consecutive calendar years (iccrom [[statutes|s|url|www.iccrom.org/about/statutes/]], article 9).]].

i trying compare 2 ipv6 addresses want create code portable. know ipv6 addresses stored in network byte order (big endian) on big-endian cpu can use memcmp across 2 in6_addr structs. easiest way same thing on little-endian machine? [edit] when want compare 2 addresses want figure out whether address less, equal, or greater other. thought memcmp endian dependent in order scans across bits in memory. actually, think memcmp work. there's not popular machine 128-bit data type know of. suspect ipv6 address carried around arrays of bytes. given network byte order big-endian, memcmp see , compare high-order byte first, want to. you right have wondered if machine's endianness matters portability, in case, think doesn't. endianness matters when we're working 16- or 32-bit integers have been copied off network, , want work them integers. here, array of bytes, concern not exist. i don't -- understand sure i'm doing first -- but, try , see!

i need way collect queries executed in oracle db (oracle database 11g) in last several hours regardless of how fast queries (this used calculate sql coverage after running tests against application has several points queries executed). i cannot use tables v$sql since there's no guarantee query remain there long enough. seems use dba_hist_sqltext didn't find way filter out queries executed before current test run. so question is: table use absolutely queries executed in given period of time (up 2 hours) , db configuration should adjust reach goal? "i need query since need learn queries out of queries coded in application executed during test" the simplest way of capturing queries executed enable fine grained audit on database tables. use data dictionary generate policies on every application table. note when writing os file such number of policies generate high impact on database, , increase length of time takes run tests. therefore should us

simple question here. have active record results this: @users = user.all later on, want data on user ispecific id. user.find('c5ab1bfc-90ac-4b59-b5d3-fd8940aab7b1') make query database. know user in list @users, there way find user @users id, without making db query, , without looping on @users object? yep can use #detect select first match in relation without firing off query: @user = @users.detect{ |u| u.id == 'c5ab1bfc-90ac-4b59-b5d3-fd8940aab7b1' } but if running simple #find query on user (user.find params[:id]), that's not going kill application, unless i'm terribly mistaken. updated: thanks d34n5 correcting me, #select iterate through entire collection whereas #detect (aliased #find) stop @ , return first occurrence.

i've searched site solution couldn't find extract purpose. i have 2 functions. first function fades in multiple elements in delay each other until every element faded in. want start second function after first done every element. i've tried .done() , .when() or .promise() figure out solution. (the fiddle below way simplified show problem. site i'm working on more complex, therefor need solution calling function after function , not settimeout() or else.) var v = $(".box"); var cur = 0; var first = function () { function fadeinnextli() { v.eq(cur++).fadein(200); if(cur != v.length) settimeout(fadeinnextli,100); } fadeinnextli(); return $.deferred().resolve(); }; var second = function () { alert('done'); }; first().done(second) https://jsfiddle.net/c633f5w8/3/ thank in advance. i didn't want rewrite have necessary stuff. illustrates use of fadein callback. https://jsfiddle.net/c633f5

we building trading system using (jms, weblogic , oracle backend) multiple trade events create journal entries merged single position row in database table. means multiple jms consumers creating multiple journal entries contending hold of single position row update it. not scalable design because no matter how many consumers have, blocked many times while waiting lock on single oracle row. (because have few distinct positions on of activity happening). as alternative, can keep inserting journal entries. every insert journal entry can further published event queue , consumer can call oracle view (which runs aggregate query) publish things downstream. this 2nd solution has other issues time take compute oracle view number of journal entries keep growing on time. is there other way can designed ?

i want compare 2 uicolors generated using [uicolor colorwithpatternimage:] equality. can't seem figure out how this. [[uicolor colorwithpatternimage:[uiimage imagenamed:@"camo2"]] isequal: [uicolor colorwithpatternimage:[uiimage imagenamed:@"camo2"]]] always returns false, whether use == or isequal. know if it's possible compare colorwithpatternimages, or cgpatterns suppose? i've tried comparing cgcolorgetpattern(color.cgcolor) doesn't work either. edit: reason have function accepts uicolor , gives me nsstring displaying user. +(nsstring *)colornameforcolor:(uicolor *)color { if ([color isequal:[uicolor whitecolor]]) { return @"white"; } if ([color isequal:[uicolor colorwithpatternimage:[uiimage imagenamed:@"camo"]]]) { return @"camo"; } ... } is insane thing do? suppose make own object has color property , colorname property... using private apis this took r

we have following use case example: we have users, stores, friends (relationships between users) , likes. store these tables in mysql , key-value stores in redis, in order read redis cache , not hit database. writes done both data stores. our app therefore fast, , scalable since hit database reads. using aws scalable redis. however, have problem when user logged in , have show list of stores, , of friends store. join, , redis not support joins directly. we'd know best way store , show data. ex: if should stored in redis table key value "store/user_who likes" , mantained every write, or maybe have hourly cron construct this. can read stored data or should construct join on demand? notice not facebook updates info in realtime, rather takes several minutes friend see of friends likes page have in common. in advance responses. depends how important you. why not store each person's friends set, , each store's likes set, , when need friends given store,

i'm building php oop mvc framework personal use. i'd know if there's way or correct implementation of following: being able call method "subclass" (not extended) "subclass". mean... have class creates new objects each subclass instead of using inheritance. let's call mainclass, , has 3 "subclasses" this class mainclass { public $db; public $forms; public $pagination; function __construct() { $this->db = new class_db(); $this->forms = new class_forms(); $this->utils = new class_utils(); } } and initialization is $mainclass = new mainclass(); i can example $mainclass->utils->show_text("hello world"); and works fine. what i'd is... within $mainclass->utils->test() (another test method), able access $mainclass->db without using global or $globals. is there alternative way of achieving this? able access $mainclass methods , submet
