i might overlooking more robust error reporting, error reporting sql server gives me line number (which 1 line) non-syntactical errors. today client had ',' in price value, dealing 72 or fields took me quite awhile find given cannot cast float message. i thinking maybe force sql run code in multiple lines line number more useful bit of info. i tried line break, putting in new lines, , adding new line characters non of worked. does know way this, or have method tracking down these errors? i think try try_convert in fields not set varchar; mean can apply function dates, numbers, , other not character data. you can take @ example: http://msdn.microsoft.com/en-us/library/hh230993.aspx hope helps!

today in class, professor introduced admissable heuristics , , stated guarantee optimality a* algorithm . i asked him explain using extreme example make obvious, couldn't. can please help? we have list of candidates, right? and each of them has etc (expected total cost) reach goal starting node (i.e. cost reach node + expected remaining cost goal (the heuristic)). now if expected cost identical actual cost, we'll literally pick nodes on shortest path (well, of shortest paths), , nothing else. since pick lowest etc, should pretty obvious why pick nodes shortest path - not on shortest path have higher etc. what if etc less actual cost? pick lowest etc, may end picking nodes not on shortest path. can never reach goal through path that's not shortest path because: the shortest path has lower actual cost non-shortest path the etc @ goal same cost reach goal via path (since we're @ goal, expected remaining cost 0) the etc less or equal actual total

i'm little bit confused this, , feel stupid asking question, want understand it. so, i'm working client side web framework, backbone, angular or durandal. framework includes routing. but of course still have server database stuff, , on, has routing. my question is: when use "client-side routing" or "server-side routing"? how "decided" whether routing performed on client side or whether request first sent web server? i have particularly hard time imagining because client side routing before server ever gets know request. i'd thankful if explain how these 2 routing systems work together. p.s.: have not included code samples because i'm not looking answer concerning particular framework, concerning routing process in general. tl;dr: with server-side routing download entire new webpage whenever click on link, with client-side routing webapp downloads, processes , displays new data you. imagine user

consider have code following: class foo { y func(x x) {...} void dosomethingwithafunc(function<x,y> f){...} void hotfunction(){ dosomethingwithafunc(this::func); } } suppose hotfunction called often. advisable cache this::func , maybe this: class foo { function<x,y> f = this::func; ... void hotfunction(){ dosomethingwithafunc(f); } } as far understanding of java method references goes, virtual machine creates object of anonymous class when method reference used. thus, caching reference create object once while first approach creates on each function call. correct? should method references appear @ hot positions in code cached or vm able optimize , make caching superfluous? there general best practice or highly vm-implemenation specific whether such caching of use? you have make distinction between frequent executions of same call-site , stateless lambda or state-full lambdas, , frequent uses of met

'://' . $request->gethttphost() . $request->getbasepath() . $path; } now make sort of toolkit or urlhelper class , define service can inject request object, seems overdone me create service such simple method. what suggest in case? guys when have created reusable functions? thanks far. for reusability, use: services (when need inject other dependencies through constructor), don't have manually everytime. helper controller, controllers extend. classes public static fun

is possible synchronize swapbuffers in many threads? when try turn on vertical synchronization (wglswapintervalext), stops threads, until doesn't tick (ex. when open 3 windows, every window has approximately 20 frames [60/3] ) every window has separate thread, , of course every thread has own swapbuffer function. swap control per-window in wgl (when set it, applied window current render context tied to). association between render context , window tied device context (see wglmakecurrent (...) ). need vsync 1 of 3 windows if reliably hitting < ~5.6 ms frame time in each. what should consider here having 1 of contexts set swap interval 1 , remaining 2 use 0 . context syncrhonized vblank (swap interval = 1 ) lead other 2 threads. say, have other 2 threads call glflush (...) , busy wait until first thread stops blocking vsync before calling swapbuffers (...) . reason glflush (...) other 2 threads accomplish useful rendering tasks while wait first (synchronized

so using setup_rmainloop() initializing r environment embedded within c++ project had problems saving images device , changed code use rf_initembeddedr(0, null) , worked fine but problem whenever error running statement , don't error details. for ex , following r script x<- 2 abc() used return following error if used setup_rmainloop() : error: not find function "abc" but rf_initembeddedr(0, null) , don't error details. any ideas how can error details ?

i know it's purpose is, , know how use it. i'm curious, code doing , why written way i? i'm referring this: def get_context_data(self, **kwargs): context = super(createlisting, self).get_context_data(**kwargs) context['action'] = reverse('create-listing') return context so i'm creating dict called context django base controller class manipulating on end? or off? super part throws me off because i'm not sure relevant information i'm getting it. the super call getting context whatever createlisting s super class is. it's can subclass view , add more context in each of subclasses - in instance you're adding action context.

i want use gridview in asp.net , when click button rows in gridview save in array , can use them 1 one. please tell me solution or suggest me book or link or ... thanks here suppose button not in grid. on click event of button can write following code string[] str = new string[gv.rows.count]; (int = 0; < gv.rows.count; i++) { str[i]= gv.rows[i].cells[0].text.tostring(); } and can have values of gridview cell against each row. now it's how use array further. thanks

enum suit: string { case spades = "♠" case hearts = "♥" case diamonds = "♦" case clubs = "♣" } for example, how can like: for suit in suit { // suit print(suit.rawvalue) } resulting example: ♠ ♥ ♦ ♣ i made utility function iterateenum() iterating cases arbitrary enum types. here example usage: enum suit:string { case spades = "♠" case hearts = "♥" case diamonds = "♦" case clubs = "♣" } f in iterateenum(suit) { println(f.rawvalue) } outputs: ♠ ♥ ♦ ♣ but, only debug or test purpose: relies on several undocumented current(swift1.1) compiler behaviors. so, use @ own risk :) here code: func iterateenum<t: hashable>(_: t.type) -> generatorof<t> { var cast: (int -> t)! switch sizeof(t) { case 0: return generatorof(generatorofone(unsafebitcast((), t.self))) case 1: cast = { unsafebitcast(uint8(trunca

i want know how can make app work in offline when user lost network connectivity. i need post data server using json post method when user not connected wifi or mobile data. i using following code detect network state using broadcast receiver , don't know how proceed after this. please assist me proceed further. public class updatereceiver extends broadcastreceiver { @override public void onreceive(context context, intent intent) { connectivitymanager connectivitymanager = (connectivitymanager) context .getsystemservice(context.connectivity_service); networkinfo activenetinfo = connectivitymanager .getnetworkinfo(connectivitymanager.type_wifi); boolean isconnected = activenetinfo != null && activenetinfo.isconnectedorconnecting(); if (isconnected) { log.e("net", "connected" + isconnected); } else { log.e("net",

is possible compile go program specific flags coverage analysis? the use case: compile app; run functional automated tests; analyse coverage; should similar gcov or python coverage . many thanks! yes, go has cover tool (as of version 1.2) incorporated test process. go test alone compile program , run automated tests may have. adding -cover flag provide statistics on test coverage. to run it: go test -cover you can output coverage profile: go test -coverprofile=coverage.out and view with: go tool cover -func=coverage.out or go tool cover -html=coverage.out for html formatted output (with colour coding). see http://blog.golang.org/cover , go tool cover -h , go testflag more info.

bear me. take little explaining. i have main page divided 3 <divs> top <div> has hyperlink in it. 1 of other <divs> (called "menu_div") has <object> in loads perl script. default, hidden when hyperlink clicked within "header_div", makes "menu_div" visible via "parent.document.getlementbyid('menu_div).style.visibility='visible'" @ same time, sets "show_hide" flag 1 if user clicks on hyperlink again, checks status of "show_hide", , if set 1, hides <div> , sets flag 0. ** in effect, each time user clicks hyperlink, box toggles on , off with box open, , running script, goes till final part. can hide box again using visibility statement above. however, <header_div> containing hyperlink still set "show_hide flag @ "1", (to popup window open) ** - once menu.pl script has closed window, if hyperlink clicked again, nothing happens (as it's resetting &quo

i use mysql dbms, have these rows in table: product_name | product_code | prod_type prod1@00x | 1 | @prod2@00x | 2 | +prod3@@00x | 3 | i wanna set prod_type = product_name without special characters. => prod_type prod100x prod200x prod300x (i can have other special characters not '@' , '+') how can that? method 1: you can use replace() method remove special characters in mysql, don't know if it's efficient though. should work. like below: select replace(replace(product_name,'@',''),'+','') prod_type table1 fiddle demo method 2: if have other special charcter go ( source ) -- ---------------------------- -- function structure `udf_cleanstring` -- ---------------------------- drop function if exists `udf_cleanstring`; delimiter ;; create function `udf_cleanstring`(`in_str` varchar(4096)) returns varchar(4096) charset utf8 begin
