with odata service, can query clientside without using dto. need dto layer if use odata svc? cons , pros if don't use dto. in our old system querying mechanism there many query service-methods returns dto collection. odata services confuses mind... seems like; responsibility of server moves client. same confusion goes on, transaction scripts. i'm curios thoughts. when on server side - thing matters odata either edm model or poco models. when genrate edmx file can considered business object or model layer , pump in namespaces. in way there no business logic applying in there. but on client side can centralize odata method invocation. since support callbacks can have view model call repository , pass call back. in way dont bloat view model extensive odata query invocation. sort of repositroy pattern talking about. hope gives direction. regards :)

i couldnt make program sleep() after using kill(pid,sigterm) can ? the code i'm using: kill(pid_of_process_to_be_killed,sigterm); sleep(5); --> not working sleep(5); --> working the solution is: kill(pid_of_process_to_be_killed,sigterm); sleep(sleep(5)); but why first sleep after kill return 0 ? your sleep() call may terminating due receiving signal. check return value. if it's positive, might want sleep() again on value. http://www.manpagez.com/man/3/sleep/ : if sleep() function returns because requested time has elapsed, value returned zero. if sleep() function returns due delivery of signal, value returned unslept amount (the requested time minus time slept) in seconds

question has been updated exclude regex possible solution. i'm trying build php function allow me strip outside of specified tags while preserving specified tags , content , not sure how this... for example: $string = "lorem ipsum <div><p>some video content</p><object></object></div><p>dolor sit</p> amet <img>" some_function($string, "<div><img>"); returns: "<div><p>some video content</p><object></object></div><img>" thanks help! ok, think figured out way based on modified version of explode_tags function posted link above: function explode_tags($chr, $str) { ($i=0, $j=0; $i < strlen($str); $i++) { if ($str{$i} == $chr) { while ($str{$i+1} == $chr) $i++; $j++; continue; } if ($str{$i} == "<") { if (strlen($res[$j]) > 0) $

background: working on winform based .net 4.0 desktop application has few threads , timers , uses gdi processing user controls. during development peep sysinternal's process explorer make sure there isn't unusual application such count of gdi handles or user objects etc. problem: while using process explorer, found threads tab application's property in process explorer shows lots , lots of entries of "clr.dll!loghelp_terminateonassert+0x58f68". normal? think not because non of other .net application (that had written in past) shows same entry in properties in process explorer. whats loghelp_terminateonassert()?

damn short titles! :p basically have entity named "threads" , have entity named "messages". have 1 many relationship threads ->> messages (and 1 one inverse relationship). what need records threads entity , each 1 need message latest timestamp (this int in "lastupdated" attribute, highest number guess suffice). i'm not sure other information may want, here screenshot of entities: i'm sure there must better way iterating through records , comparing threadids? thank you. once have individual thread objects, need sort on messages objects , take topmost message object. the easiest solution create method in thread class this: - (messages *) lastupdatedmessage{ nssortdescriptor *sort=[nssortdescriptor sortdescriptorwithkey:@"lastupdated" ascending:no]; nsarray *sortedmessages=[self.messagesinthread sortedarrayusingdescriptors:[nsarray arraywithobject:sort]]; return [sortedmessages objectatindex:0];

my c++ compiler complains when try initialize int member variable in class definition. tells "only static const integral data members can initialized within class". can please explain rationale behind restriction (if possible example). the rationale "low-level" nature of c++. if allow this, compiler need generate initialization code constructors not entirely clear developer. after might necessary initialize members of base classes on construction of derived class when base class constructors not explicitly invoked. static const integral variables not need intitalization upon object creation.

i have managed use sapi text-to-speech in delphi/lazarus using following code: procedure tform1.button1click(sender: tobject); var spvoice: variant; begin spvoice := createoleobject('sapi.spvoice'); spvoice.speak('hello world!', 0); end; this code automatically chooses english standard voice. since need localize spanish investigated if system (windows xp standard spanish) had spanish voice or needed install it, , how change default voice, no luck far. therefore questions are: how can know if system has spanish voice installed or need install it? supposing have voice need installed, how can make sapi use voice instead of standard one? i guessing can spanish voice using following code (c0a code spanish language): spvoice.getvoices('','language=c0a').item(0) but not know how set voice used. edit : avoid confusions, need make compatible delphi , lazarus, being last 1 primary development tool. no freely available version

i experimenting splice() method in jconsole a = [1,2,3,4,5,6,7,8,9,10] 1,2,3,4,5,6,7,8,9,10 here, simple array 1 10. b = ['a','b','c'] a,b,c and b a.splice(0, 2, b) 1,2 a,b,c,3,4,5,6,7,8,9,10 when pass array b third argument of splice, mean "remove first 2 arguments of index zero, , replace them b array". i've never seen passing array splice()'s third argument (all guide pages read talk list of arguments), but, well, seems trick. [1,2] removed , [a,b,c,3,4,5,6,7,8,9,10]. build array, call c: c = ['one','two','three'] one,two,three and try same: a.splice(0, 2, c) a,b,c,3 one,two,three,4,5,6,7,8,9,10 this time, 4 (instead of 2) elements removed [a,b,c,3] , c array added @ beginning. knows why? i'm sure solution trivial, don't right now. array.splice not support array third parameter. reference: https://developer.mozilla.org/en/javascript/reference/global_objects/array/splice u

the main issue if tab selected 'select' event doesn't fire if set same tab id again. reason required in update content located in tab. need way fire 'select' if specify selected tab id. in theory should work like: tabcontrol.tabs('select', -1); tabcontrol.tabs('select', selectedtab); but 'select' takes 0 based index, doesn't reset tabs desired , doesn't raise event again. any solution? i wouldn't recommend selecting tab twice because need reload contents. instead solved same issue calling tabs() 'load' method instead of 'select'. var selectedtab = tabcontrol.tabs('option', 'selected'); tabcontrol.tabs('load', selectedtab);

assume doing validation on text box bound property. on setter property might decorate property following [regular3xpression("^[0-9]$", errormessage = "must integer.")] however, if user types in letter in textbox, validation never happen because exception type converter. in other words, if had validation summary connected; display error "input string not in correct format." not desired "must integer". am missing something? seems broken, there way work around this?

i'm in process of creating simple user control; imagebutton. i've bound image button , i've decided add tooltip. i'm having troubles. seems can hard-code text tooltip in xaml control, when it's bound it's returning empty string. here's xaml control: <button x:class="bcocb.dacms.controls.imagebutton" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" mc:ignorable="d" d:designheight="300" d:designwidth="300" name="this" style="{staticresource disabledbutton}"> <image source="{binding elementname=this, path=source}" /> <

on old computer, eclipse validate jsp files. new installation, no longer , there not option apply jsp validator under project->properties->validation. missing configuration, plugin, or package? appreciated. my suspicion don't have eclipse java ee developers installed. have eclipse java developers. you need web tools contains jsp validators. check comparisons of eclipse here .

i've got task<t>: task<a> sometask = ... this task can result in being successful, faulted or cancelled. i want transform result when task successful, , preserve outcome if not. this seems difficult when sometask throws exception. what i've tried: task<b> resulttask = startmytask().continuewith<b>( t => foo(t.result), taskcontinuationoptions.onlyonrantocompletion); this results in resulttask being cancelled if sometask faults. want fault. task<b> resulttask = startmytask().continuewith<b>( t => foo(t.result)); this breaks visual studio debugger because .result throws exception. if press f5, resulttask faults expected, smells. is there way let resulttask have same outcome sometask if sometask faults? essentially i'm trying express tasks: int f() { throw new someexception(); } string g(int x) { return x.tostring(); } try { string result = g(f()); } catch (someexception e)

can please explain why compiles , why t end type int& ? #include <utility> void f(int& r) { ++r; } template <typename fun, typename t> void g(fun fun, t&& t) { fun(std::forward<t>(t)); } int main() { int = 0; g(f, i); } i see on gcc 4.5.0 20100604 , gdb 7.2-60.2 because of perfect forwarding, when argument p&& lvalue, p deduced argument's type plus having & attached. int & && p being int& . if argument rvalue p deduced argument's type, would int&& argument p being int if pass, example 0 directly. int& && collapse int& (this semantic view - syntactically int& && illegal. saying u && when u template parameter or typedef refering type int& , u&& still type int& - i.e 2 references "collapse" 1 lvalue reference). that's why t has type int& .

i have 30 smart-sensors distributed in several private networks internet access (all of them). have establish persistent connection (socket) between sensors , server has public ip. a user can access each sensor through website (django) , send or data. from point of view, how can ensure several persistent , private connections? found https://github.com/gregmuellegger/django-websocket , think not suitable application because cannot recover existent socket connection other django views. any suggestions received. i found approach using twisted perspective broker json-rpc in server providing methods support each smart sensor, , other side each sensor use json library authenticate (basic) , send data. what think? solution? post results test it. set seperate server keeps persistent connections, , allow django application query it. twisted can provide great framework writing simple, single purpouse servers, , there tutorial on how write xml-rpc server here . python has e

i have 2 existing indices in db below create nonclustered index indextable1 on table (fkanothertable) create nonclustered index indextable2 on table (fkanothertable) include (pktable) i had hunch , research seems point queries call #1 satisfied #2 , #1 wasteful. couldn't find definitive answer though. is assumption correct , can drop #1 , potentially improve performance? yes. #2 entirely covers #1 , possibly vice-versa in fact. pktable clustered index key? if included in #1 (at key level because non clustered index not declared unique). if pktable not clustering key queries seeking on #1 still satisfied #2 #2 may occupy more pages making scans have used #1 tad less efficient.

i running tool in prolog, , after execute it, result appear on screen, inside prolog shell. how can copy result file? you never said prolog interpreter you're using. code works edinburgh-compatible version of prolog, swi-prolog (on fedora) in case. if have file hello.pl: hello_world :- write('hello world!'). then consult('hello'). qsave_program(hello,[stand_alone(true),goal(hello_world)]). quit interpreter , in shell: $chmod +x hello ./hello > output_file it doesn't return shell when it's done, need find way check whether or not program finished execution , ctrl-d , check output_file hope helps

my test application is #include <sys/types.h> #include <sys/wait.h> #include <signal.h> #include <unistd.h> #include <stdio.h> #include <stdlib.h> #include <string.h> #include <fcntl.h> int main(int argc, char *argv[], char *envp[]) { int fd[2]; if(pipe(fd) < 0) { printf("can\'t create pipe\n"); exit(-1); } pid_t fpid = fork(); if (fpid == 0) { close(0); close(fd[1]); char *s = (char *) malloc(sizeof(char)); while(1) if (read(fd[0], s, 1)) printf("%i\n", *s); } close(fd[0]); char *c = (char *) malloc(sizeof(char)); while (1) { if (read(0, c, 1) > 0) write(fd[1], c, 1); } return 0; } i want see char-code after each entered char. in fact *s printed after '\n' in console. seems stdin (file desc 0) buffered. read function buffer-less, isn't it? wrong. upd: use linux. so solution is #include <stdio.h> #include <stdlib.h> #

how redirect after click close button? $(document).ready(function() { var $dialog = $('<div></div>') .html('this dialog show every time!') .dialog({ autoopen: false, title: 'basic dialog' }); $('#opener').click(function() { $dialog.dialog('open'); // prevent default action, e.g., following link return false; }); }); you define callback close event in following way well: $(document).ready(function() { var $dialog = $('<div></div>') .html('this dialog show every time!') .dialog({ autoopen: false, title: 'basic dialog', close: function(ui, event) { $(this).dialog('close'); // redirect on here. } }); });

well, scenario may familiar because ve been @ quite while though closer ever still has never worked. going put extremely clear , detailed definitively nail it. scenario we have 1 long url line upon clicking 2 things should happen @ once (the current situation ony happens 1 of them 1 or 2) 1) jquery sensitive click , opens slide panel 2) same jquery has line makes div inside panel populated (thanks php sql powered file) so, issue line. 2 have been proposed, none trick 1 , 2 mentioned above. although both syntactically correct, is, order of dots , quotes correct, none of lines opens slide , and populates div. 1st line proposed: this line lets slide panel open not transmit id_cruise value $soutput .= '"<a href=\"#\"' .' id=\"' .addslashes($arow['id_cruise']) .'\" class=\"flip\">'.addslashes($arow['from_country']).'</a>",'; 2nd line proposed this line not open , not p

i'm using asp.net 4.0. i've got following code returns error of "cannot access disposed object. object name: 'datacontext accessed after dispose.'." public ienumerable<batchheader> getheaders() { using(nsfchecksdatacontext context = datacontext) { ienumerable<batchheader> headers = (from h in context.batchheaders select h); return headers; } } if change to: public ienumerable<batchheader> getheaders() { using(nsfchecksdatacontext context = datacontext) { return context.batchheaders.tolist(); } } it work fine. i'm using method populate radgrid. can explain why second method work not first? thanks.

is there way compare 2 functions in haskell? my thought answer no since functions not derive eq type class. i'm trying write pretty trivial function , seems normal sort of thing do: search :: ((enum a) => -> a) -> card -> [card] search op x list = if (op == succ && rank x == king) || (op == pred && rank x == ace) [] else let c = [ n | n <- list, rank n == op (rank x)] in if length c == 1 x : search op (head c) list else [] error message: no instance (eq (rank -> rank)) arising use of `==' basically either searches or down list of cards looking match either next or previous ranked card x, building list. taking 'pred' or 'succ' function operator works both forwards , backwards. however, need check doesn't go out of bounds on enum otherwise throws exception. so i'm looking way pre
