i ran across problem, wanted function work on both doubles , integers , wondered, why there no common interface number types (containing arithmetic operators , comparisons). it make writing functions math.min (which exist in gazillion overloads) way more convenient. would introducing additional interface breaking change? edit: think using like public t add<t>(t a, t b) t: inumber { return a+b; } or public t range<t>(t x, t min, t max) t:inumber { return max(x, min(x, max), min); } if want such kind of "generic" arithmetics option in strongly-typed language such c# quite limited. marc gravell described problem follows : .net 2.0 introduced generics .net world, opened door many elegant solutions existing problems. generic constraints can used restrict type-arguments known interfaces etc, ensure access functionality - or simple equality/inequality tests comparer<t>.default , equalitycomparer<t>.default singletons

i'm trying use mbprogresshud show loading animation while i'm accessing information smooth out process of going uitableview listing uiwebview has detailed information of item selected. if call [self fetchplayer]; without using mbprogresshud have no issues , works fine albeit without animation. if call [self loadinganimation]; half works. first time select uitableview loads correctly every time, if go , select same or different item quite null values playerdetails items. i'm not sure mbprogresshud method doing cause here code. nslog displaying correct information - main class calling 2 methods not output correctly. - (void)loadinganimation { // hud dispable input on view (use higest view possible in view hierarchy) hud = [[mbprogresshud alloc] initwithview:self.navigationcontroller.view]; // add hud screen [self.navigationcontroller.view addsubview:hud]; hud.labeltext = @"loading"; // show hud while provided method executes in new thre

ok, have 2 tables in mysql. 1 table holds customer information, other holds phone numbers. need join these tables in 1 query select 2 phone numbers phones table customer information. right query is: select customers.name, phones.phone, phones2.phone customers left join phones on phones.customerid=customers.id left join phones phones2 on phones2.customerid=customers.id group customers.id; however, returns same phone number phone 1 , phone 2. need offset phones2 1, don't know how syntactically. the phones in separate table because it's 1 many relationship. i need in 1 query because i'm exporting directly csv. help appreciated. in advance. to avoid getting same phone number twice change this: left join phones phones2 on phones2.customerid=customers.id to this: left join phones phones2 on phones2.customerid=customers.id , phones2.phone <> phones.phone

i have parent many children, fine. against each parent trying store default_child. want make default_child mandatory can not think how this. creating parent first mean violating mandatory default_child condition. creating child first mean violating it's fk condition. how others deal this? thanks! constraints can typically marked "deferrable", means can ask database defer checking them until commit time. lets resolve situations 1 constraint needs violated temporarily while building transaction, satisfied again time you're ready commit.

is there 'standard' way specify task continuation should run on thread initial task created? currently have code below - working keeping track of dispatcher , creating second action seems unnecessary overhead. dispatcher = dispatcher.currentdispatcher; task task = task.factory.startnew(() => { dolongrunningwork(); }); task uitask= task.continuewith(() => { dispatcher.invoke(new action(() => { this.textblock1.text = "complete"; } }); call continuation taskscheduler.fromcurrentsynchronizationcontext() : task uitask= task.continuewith(() => { this.textblock1.text = "complete"; }, taskscheduler.fromcurrentsynchronizationcontext()); this suitable if current execution context on ui thread.

i have display 2 images single mouseover . when mouseover image, first, image displayed time delay of 5000, image needed display same hover. on mouseout display original image. i not familiar javascript , jquery. can please give me idea how this. what did is, $('.image1').mouseover(function() { setinterval($(this).removeclass(.image1).addclass('image-over1'),5000); $(this).removeclass(.image1).addclass('image-over2'); }); $('.image1').mouseout(function() { $(this).removeclass('image-over1'); $(this).removeclass('image-over2').addclass(item); }); $('.image1').click(function(){ document.location='index.php?page='index.php'; }) the .hover() function lets specify both mouseover/mouseout @ same time, , need make function setinterval : $('.image1').hover(function(evt) { // mouse on function. // dom element got mouseover. var target = evt.t

when using paypal standard or paypal express, customers directed paypal website either complete sale, or sign in paypal accounts verify payment, respectively. there significant percentage of customers not complete sale point. magento reserves order increment id these abandoned carts, , sales_flat_quote_address table contains address details, these don't appear in abandoned carts report or anywhere else can see in admin. it helpful able display order details customer has entered contact information in shipping/billing steps of checkout, , hence should open being contacted reactivate checkout. i'm looking architectural suggestions on how display these details , reduce order leakage? new report best, or module adds node under sales menu. don't have experience in writing new reports, , sales grid/views quite complex... thanks, jonathan you can customize abodoned cart report display these carts. collection method responsible report called mage_reports_m

to communicate between views , objects persistant information, example username , choice of font size display, considered form put these onto application object, or more efficient put them static singletons? for example: public class application { static void main (string[] args) { uiapplication.main (args); } public static username {get;set;} } i don't think there's difference performance-wise between putting static objects application vs singletons vs static classes. for things colors , fonts, prefer create static classes hold each type of object, example write this: public static class colors { public static color toolbarcolor = color.black; .. } this makes easier change colors around entire app without having searching around everywhere. same thing fonts, images, etc.

i know basic definition of recursive function.....but want know impact on memory?? why not chosen on loop or iteration? c++ not mandate tail call optimization, recursive functions can trivially converted loops may still take space linear in call depth (storing frame). additionally, c/c++ not necessarily detect stack overflow, that's problem potentially deep calls. edited have more qualified language ("necessarily") edit some people seem hung on fact specific compilers such gcc , clang perform tail call optimization and/or stack overflow detection. point is, if not mandated, unsafe. example, gcc performs tail call optimization @ -o2, -o3 , -os. so, if program depends on tail call optimization being performed, program mysteriously die when compiles without optimization flag (on gcc). if programming practice, then, means, can continue write programs depend on compiler flags. or ones depend on compilers. optimization not optional.

i wondering how this: at moment have this, can see selecting status 0 & 2 , later in code updating status 0 97 , status 2 99 select id_queue, status table status in (0,2) order status, id_queue asc update; update table set status = 97 id_queue= " + id_sms + "; update table set status = 99 id_queue= " + id_sms + "; i want select & update , , row ids of id_queue later use can help? much appreciated. update table set status = case status when 0 97 when 2 98 end status in (0, 2) if want save id_queue values, you'll either need create temp table, or store them in program outside database. i'd second reasonably sized set - lot less housekeeping if can keep them in scope in program.

i having application build using j2me lwuit. need send e-mail app. to make application smaller, i'd suggest implement smpt on socketconnection . small e-mails shall pretty straightforward: socketconnection connection = (socketconnection)connector.open("socket://your.smtp.server:25"); datainputstream = sc.opendatainputstream(); dataoutputstream os = sc.opendataoutputstream(); //now smtp chat server using approach may allow make application depend on midp/cldc profiles, easier portable other phones (at least in theory).

i suspect shouldn't using static factory method here, mean time @ loss how implement this. following code gives compile error on line in createopenport assigns _currentport_datareceived because delegate method isn't static. how can resolve this, preferably using non-static factory method? public static serialportservice createopenport(string portname, int baudrate, parity parity, int databits, stopbits stopbits) { var service = new serialportservice { _currentport = new serialport(portname, baudrate, parity, databits, stopbits) }; service._currentport.datareceived += currentportcharsreceived; service._currentport.open(); return service; } void currentportcharsreceived(object sender, serialdatareceivedeventargs e) { var port = (serialport) sender; var chars = new char[port.bytestoread]; var x = port.read(chars, 0, chars.length);

can explain why request tokens must exchanged access tokens after user approval? why not pretend request token access token once user has approved access? short answer : authenticate application. refer youtube's oauth process flow diagram oauth 3-legged protocol. in particular case, youtube needs authenticate 2 different entities - a) user , b) application needs accss. now, after user grants access (step 10 in diagram), youtube knows "user x wants grant application y access youtube". hasn't yet verified application y. rogue application can perform steps step 10 pretending valid, known application - , such action must prevented. in last 3 steps, application verifies youtube signing request. once done, youtube can safely provide access token application.

what warning mean in jersey 1.4: warning: sub-resource method, public final java.lang.string com.xxx.render(), uri template, "/", treated resource method this how method looks: @get @produces(mediatype.application_xml) @path("/") public final string render() { return "test"; } why need specify such path method? @get enough tell jersey default method entire class (i'm assuming class has @path("/myres") annotation).

in visual studio, when you're debugging breakpoints can change line of code next execute dragging execution cursor line; lets skip if statements , like. i idly wondering if there similar feature in delphi knew about? i've been having around in cpu window (delphi 2006) seem able run through instructions in order, not skip them. in cpu view can right-click , choose "new eip (ctrl + n)" set instruction pointer.

how can access element: <input type="submit" value="save xml" onclick="some code goes here"> more info: have access programmatically web page , simulate clicking on button on it, generate xml file hope able save on local machine. trying using htmlunit libraries, examples find use getelementbyid() or getelementbyname() methods. unfortunately, exact element doesn't have name or id, failed miserably. supposed thing have use getbyxpath() method got lost xpath documentation(this matter new me). have been stuck on couple of hours need can get. in advance. there several options xpath select input element. below 1 option, looks throughout document input element has attribute named type value "submit" , attribute named value value "save xml". //input[@type='submit' , @value='save xml'] if provide little bit more structure, more specific (and efficient) xpath created. instance, might wor
