is possible created function in web service have multiple threads, 1 returns value user, , 1 continues process transaction? i've never used multithreading before , seems able running transaction asynchronously. no code has been written yet. trying see if possible before begin coding. although can fire off threads , like, other .net application have take account operating environment. any long running process should handed off process windows service web server worker processes can , recycled , goes threads. you're tying threads used further service requests web application. in regards paul abbot said, in principle if had way of returning kind of work id client poll status of processing in request, , can apply within same process or out of process in external service.

i'm writing actionscript3 flash game, needs access rest services specified sponsor (buyer of game) - things highscores etc. know how use urlloader, urlrequest, set urlrequestheader. unfortunately sponsor on shared hosting , can't put crossdomain.xml in server root, can't connect localhost flash game ( same origin policy ). learned there way connect rest api proxying calls through php file on different server. so have proxy.php file on private server, , calling like: www.myserver.pl/scripts/proxy.php?url=http%3a%2f%2sponsorserver.hosting.com/api/init.json (url=urlencoded address) it connects (returns http 200), don't know yet how pass custom headers init.json script; tried combinations sending them through , post, calling script through , post (using restclient ff extension). this proxy.php: $getvars = 'myparam1=3;&myparam2=data;'; // test purposes $url = $_get['url'] .

i have list view when populated data doesn't scroll. why happening think there's no problem java code. think problem xml. here's xml <relativelayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@drawable/bg_main" tools:context=".ireportmain" > <relativelayout android:id="@+id/header" android:layout_width="match_parent" android:layout_height="83dp" android:layout_alignparentleft="true" android:layout_alignparenttop="true" android:background="@drawable/bg_nav" android:gravity="top" > <imageview android:id="@+id/logo1" android:layout_width="150dp" android:layout_height="80dp" android

i have adbanner on first screen , wondering if ok copy , paste onto other screens or require coding ? p.s having adbanner on more 1 screen make more revenue or 1 screen fine? having ad banner on multiple screens increase likelihood of user noticing ad , clicking through (which generates revenue you). make sense code against api ad , display on each screen api handle tracking click throughs , refreshing new ad after specified amount of time.

i have following relations : class cartitem belongs_to :cart belongs_to :product class product (<=> category) has_many :cart_items class cart has_many :cart_items when adds product cart, creates line in cartitem table cart.id , product.id. can add et remove product cart on edit page, works. but add or remove more 1 product cart @ same time. need input number field when customer put number want add/remove. however, don't manage because in edit form, if put field called example "number" (for each product) error appear because there no attribute "number". should add "field_tag" how can work ? in advance i work on ecommerce gem written rails called spree . here's how we've solved problem. we have 4 models: variant , product , order , lineitem . these form basics of our ordering system. variant can considered "mutation" of product. have tshirt come in red, green or blue. product tshirt, while colours variant

i hope can give idea on how improve performance of scrolling on app. basically have tiles/images being generated in secondary thread, , once ready add them relativelayout on specific position layoutparams. i'm setting size of relativelayout fixed avoid complexities. relativelayout 1 add scrollview. i listen scroll change event of scrollview, able request new tiles when scroll new position. when happens, new tiles generated on secondary thread, , @ same time information remove old tiles not necessary anymore (this helps keep quantity of tiles not blow out memory). but, main problem here while scrolling , adding/removing tiles (using addview() , removeview()) scrolling jerky. have same app in ios, using same approach , scrolling perfect. here's have: // main activity relativelayout tilecanvas = new relativelayout(this); tilecanvas.setlayoutparams(new layoutparams(800, 10000)); scrollview scroll = new scrollview(this). scroll.addview(tilecanvas); setcontentview(scrol

edit! changed answer own after lot of follow-up research showed there isn't simple answer question. see below! so, in followup last question, i'm trying better handle on best javascript practices optimize performance. following example, i'm testing in chrome 28.0.1500.70 using in-browser profiler. i've got math functions encapsulated in object getting called few hundred k-times second , trying shave bit of execution time. i've done optimization making local copies of parent objects locals locals in called functions , got decent (~16%) performance boost. however, when did same calling function parent object, got huge (~100%) performance increase. the original setup calcneighbors calling fellow parent object function cirind via this.cirind. making local var copy of cirind , calling instead gave huge performance gain, less half execution time before calcneighbors. however, making cirind inline function in calcneighbors caused return same slower per

using mac os x 10.8.4, chrome 27 (latest stable). i have script every x seconds (with setinterval() ) makes ajax call jquery see if there's still connection server (heartbeat). posts data , depending on if succeeded or not, calls other functions. it works fine until mac goes sleep (screen black, hdd powers down, etc.), wake , ajax call failed , tried call function (variable) apparently no longer exists: post http://mywebsite.com/index.php jquery.min.js:4 uncaught typeerror: cannot call method 'onlost' of undefined onlost function within other variables, such mylib , anotherlib . instantiated in loading page. code lot more complex, here's simplified version: var mylib = new mylib(); mylib.anotherlib = function() { this.onlost = function() { ... }} setinterval() { function() { $.ajax({ failed: mylib.anotherlib.onlost }); }, 10000); after error occurs, script behaves normal. can access mylib , onlost() fine. know browsers implement settimeout() , s

this simple question, i've read details using case in where clause, couldn't able make clear idea how use it. below sample query: 1 select * dual 2 (1 =1) 3 , (sysdate+1 > sysdate) 4 , (30 > 40) 5 , (25 < 35); i have procedure i_value in parameter. need ignore 4th line if i_value 's' , need ignore 5th line if i_value 't'. thanks in advance. i think best way solve problem: select * dual (1 = 1) , (sysdate + 1 > sysdate) , case when i_value = 's' case when (25 < 35) 1 else 0 end when i_value = 't' case when (30 > 40) 1 else 0 end end = 1; of course, use dynamic sql, it'd more difficulty , less effectively.

i have amazon ec2 instance ebs volume. standard ebs volumes billed $0.10 per 1 million i/o requests now not able guess how normal i/o request normal server. , in max case how large can be. how can metrics or stats somewhere can see how max busy server can see how max can get? i know can find way of controlling it. presently, have 1 public site not traffic want know if traffic increases how max can go. if you're worried price predictability may consider switching piops volume on standard ebs volume. ebs web site : with provisioned iops volumes, charged amount provision in iops (input/output operations per second) x percentage of days provision month. the predictable billing model of piops volume (not mention performance) can make them attractive workloads.

let's suppose have such structure of classes: base class object , parent class bool , int , float , bytes , unicode classes. before had functions bool cast_bool() const , int cast_int() const , etc. virtual functions in object class , in child classes i've implemented these functions separately. it seems better solution implement template <typename type> type cast() const function instead. however, since c++ prohibits virtual template functions don't know how can complete task. need provide template <typename type> type cast() const object , childs. generic object::cast<type>() const throw casterror ; every type bool , int , etc. i'll implement functions bool::cast<bool>() const , int::cast<bool>() const , etc. i'm planning add cast builtin objects, though overload operator bool() const , operator signed short() const , etc. if there no implementation, template must switch generic form object class, throwing error. there w

according docs: https://developers.google.com/appengine/docs/quotas#channel the daily quota billing enabled apps sending data through channel api capped @ 2gb. correct? i think it's small. if had app sent data every 5 seconds (at 32kb per message) hour, i'd on quota in hour 90 users. 2gb volume cap cloud solution seems bit small. am missing something? i don't think correct. billing enabled app shows in quota details: channel data sent 0% 0% 0.00 of 2,088.13 gbytes

if (from razor view), call c# helper (i.e compiled dll). there performance loss here? e.g i use @model.user.getfriendlyname(); (calls method in model inside dll). or pass friendlyname razor view, (storing in viewmodel initially). is there speed difference between these 2 methodologies? calling user.getfriendlyname() isn't slower in view anywhere else. razor views compiled classes behind scenes. one thing keep in mind if method gets database cause queries , if using orm lazy loading context/session lost then.

recently i've got confused following situation. difference between 2 if usage: case 1 amount=10 if [[ $amount -eq 10 ]] echo "something" fi script output: $ ./1.sh case 2 if [[ amount -eq 10 ]] this works (note variable name doesn't contain $ ). so question how work without dollar sign in variable name. p.s. i'm using posix shell on hp-ux. man bash arithmetic evaluation ... shell variables allowed operands; parameter expansion per‐ formed before expression evaluated. within expression, shell variables may referenced name without using parameter expansion syntax. in context shell not expect numerics, expands strings variables. makes sense me.

this can seems simple question ... crux how match button delegate signature void, object, eventargs method or use event delegate. as example, have code button changes color when it's clicked. however, button1.click += new eventhandler(kk.changecolor); carries eventargs button changecolor(object sender, eventargs e) method, meaningless rest of code use coloreventargs; , button1.click += delegate(object sender, eventargs e){ kk.changecolor(sender); }; doesn't allow later removal of delegate later in code. so better? adding unnecessary parameters methods match button delegate or suffering not being able remove delegate later ? or how change delegate signature of button? it seems there must 'cleaner' way this? will appreciate advice. " it seems there must 'cleaner' way this? " in opinion, better design depends on changecolor method do. if doing specific operation closely related event button clicked, leave real even
