i'm trying develop simple hello word application assignment in java, i'm stuck on how begin, have downloaded simulator (leibcit) cant figure out how make work servers, i'm running tomcat jboss open other simulators. do perhaps have detailed description on how can go developing application user dials code, maybe: *111# i bring menu hello // user selects 1, opens menu 1 how 2. previous screen bye // ends session. any appreciated. i'm new here , sorry if question's been asked, looked around couldnt find understand.

i have used html2canvas.js in project convert element(body) canvas , convert canvas image. element contains images load cross domain. canvas create element working perfectly, when try canvas.todataurl("image/png"); gives error securityerror: operation insecure please me solve issue. canvas.todataurl("image/png"); working fine when image not load cross domain. thanks in advance. not html2canvas issue--just security issue. if lucky... you can use imageobject.crossorigin='anonymous' when downloading cross domain image. requires both server , browser allow anonymous x-domain transfers. sadly, servers , browsers don't yet allow. alternatively don't go cross-domain...serve image on own website. alternatively wrap image request in json request. here's script that: http://www.maxnov.com/getimagedata/

i've tried use ir in rails4 app, code class workspacescontroller < inheritedresources::base private def permitted_params params.permit(:workspace => [:name, :owner_id]) end end raises activemodel::forbiddenattributeserror exception. the same problem following code def permitted_params params.permit(:name, :owner_id) end whats wrong code? ps: i've tried following protip http://blog.josemarluedke.com/posts/inherited-resources-with-rails-4-and-strong-parameters 4.0rc1 doesn't work :( i had same problem. you need put permitted_params method public method in controller class. it's not private method. i hope help.

oracle / pl sql trigger have table dealing residential properties called unit_tbl. the primary composite key (unit_num, complex_num , owner_num) many owners can own same unit in same complex. other columns include num_of_bedrooms (ie 4, 3, 2, 1) , property_type (ie house, duplex, apartment, condo). assume following statement entered: insert unit_tbl (unit_id, complex_id, owner_id, num_beds, property_type) values (001, 1000, 010, 3, 'apartment'); i'd raise error if same unit_id , complex_id entered owner (of same property) if num_beds not match previous entry or if property type not match previous entry. for instance, error raised if insert or update follows: insert unit_tbl (unit_id, complex_id, owner_id, num_beds, property_type) values (001, 1000, 011, 2, 'apartment'); -- num_beds here not match same property entered. i've tried creating trigger: create or replace trigger unit_consist_check before insert or update on unit_tbl

i understand that, given expression initializing forwarding/universal reference,lvalues deduced of type t& , rvalues of type t (and not t&&). thus,to allow rvalues, 1 need write template<class t, enable_if<not_<is_lvalue_reference<t> >,otherconds... > = yes> void foo(t&& x) {} and not, template<class t, enable_if<is_rvalue_reference<t>,otherconds... > = yes> void foo(t&& x) {} my question , why forwarding references, rvalues deduced of type t , not t&& ? guess, if deduced t&& same referencing collapsing rule works t&& && same t&& . because @ time, deducing rvalue a arguments a&& instead of a seen unnecessary complication , departure normal rules of deduction: http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2002/n1385.htm http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2002/n1377.htm we didn't know if 1 exception of deduction

i switched idea had have problems eclipse. overall feels great. however, 1 issue annoys me. building simple application take lot of time. if change 1 line, building takes 1min. in eclipse took 3 seconds. i've searched lot how improve performance, nothing helped. use 64 bit version of idea, increased ram, gave compiler higher heapsize (java , android dx compiler), checked "make project automatically" , "compile independent modules in parallel". didn't change situation. why eclipse faster in building .apk idea is? how handle long process? in case antivirus software causing issue (zonealarm). please vote crazycoder's comment up, had correct intention. build , launching app takes 2 seconds now. great, great.

for program need method takes screenshot every half minute. googled , came method: public static bitmap capturescreen() { bitmap bmp = new bitmap(screen.primaryscreen.bounds.width, screen.primaryscreen.bounds.height, system.drawing.imaging.pixelformat.format32bppargb); graphics gfx = graphics.fromimage(bmp); gfx.copyfromscreen(screen.primaryscreen.bounds.x, seen.primaryscreen.bounds.y, 0, 0, screen.primaryscreen.bounds.size, copypixeloperation.sourcecopy); return bmp; } well works fine first 200 uses of method or so. function crashes @ copyfromscreen , says caused invalid argument exception. i'm confused why because parameters don't change. could function has bug? if there alternatives take screenshot? probably 2 separate failures dispose. both graphics , image / bitmap implement idisposable , "obvious" of 2 here: using(graphics gfx = graphics.fromimage(bmp)) { gfx.copyfromscreen(screen.

pf1==pf2 pf1 , pf2 point same array element pf1>pf2 pf1 higher address location pf1<pf2 pf2 lower address location i want know if third sentence should be： pf2 higher address location ？ the third statement should either: pf2 higher address location pf1 lower address location these statements equivalent in context. original quote got caught not making mind of 2 correct statements wanted make , ended being erroneous combining them. under memory addressing schemes such segmented addressing on 8086, possible have 2 different values segment:offset refer same address (because segments overlap). depending on whether (or how) pointer values normalized before comparison, might have pf1 < pf2 pointers still refer same address. however, sufficiently esoteric you're unlikely ever run such problem in practice.

i know 1 can either splice item out of array, or delete delete . former approach can cause concurrency problems, e.g. if 1 thread walking on array while has shifted or spliced. delete doesn't have issue if foreach used on array, since foreach walk on holes in array. however, array can't keep growing forever , necessitate sweeping, potentially causing same issue in case of splice. sounds need locking, i'd amused if javascript had facilities it. thoughts? no, can't have concurrency problem javascript isn't multithreaded. if use webworkers won't have problems no data shared (workers communicate passing messages). in node.js script isn't multi-threaded. so use splice , there no need lock array.

i have little problem. i installed eclipse cdt , created c project using mingw , simple warnings (like "unused variable" etc) shown errors. the program build fine , can run it, these errors annoying. i checked compiler settings , "warnings errors (-werror)" unchecked. what do? if -werror checked, build fail. way should check enforces take care of warnings right beginning. you can suppress warnings (but not all), special options gcc (mingw). can see options needed suppress or warning in end of warning itself. nevertheless, recommend against it. it's rather better resolve warnings right beginning. strive design projects in way able built -pedantic -wall -wextra -werror options. there 3 main benefits of approach: your code bulletproof; your code conform standard closely; your code more portable across different compilers (as of them tend treat warnings errors default). remember, leaving annoying warning flood bad habit, , should r

this may turn out more of style question, i'm little stumped on how best design restful api. let's want provide following api calls: get /player returns current player get /player/{id} returns specified player post /admin/player/{id} registers specified player put /admin/player/{id} updates specified player as surmised, last 2 require administrative rights, , first 2 merely require user logged system. so question involves how best lay api out resources. first instinct create single playerresource doesn't have class-level @path annotation, rather defines each method @path("player/...") or @path("admin/player/...") accordingly. work? smells bit me, there better way style-wise? alternative can think of create separate resource class contain admin-only calls, smells me since i'd have 2 resources dealing same model class. i'm looking little guidance on how best design thing. first restful web app, forgive horrible ign
