if have function takes int *& , means? how can pass int or pointer int function? function(int *& mynumber); whenever try pass pointer function says: error: no matching function call 'function(int *)' note: candidate 'function(int *&)' it's reference pointer int. means function in question can modify pointer int itself. you can pass pointer in, 1 complication being pointer needs l-value, not r-value, example int myint; function(&myint); alone isn't sufficient , neither 0/null allowable, as: int myint; int *myintptr = &myint; function(myintptr); would acceptable. when function returns it's quite possible myintptr no longer point pointing to. int *myintptr = null; function(myintptr); might make sense if function expecting allocate memory when given null pointer. check documentation provided function (or read source!) see how pointer expected used.

in asp.net application set <system.web><globalization culture="pl-pl" uiculture="pl-pl" /> to have numbers , dates in culture. surprisingly noticed methods invoked job scheduler (quartz library) use en-us? why that? web.config globalization relatively simple - sets thread locale when request being processed. seem invoking methods non-asp.net thread, using quartz.net scheduler. invoker has set thread locale before calling methods, in job code, set locale manually, call methods need, so: thread.currentthread.currentculture = new cultureinfo("pl-pl"); thread.currentthread.currentuiculture = new cultureinfo("pl-pl");

how memory allocated in slave nodes execution of mpi programs ? how slave nodes know amount of memory reserve ? happens when slave node can't find data wants access ? this not homework problem , question tried came in mind , could'nt find on googling with non-specific question, best answer can expect non-specific when programming using mpi typically write single program launched (via mpirun/mpiexec, or batching system eg. torque) on set of notes. the master-slave model 1 approach. the memory allocation typically under program control, in application allocate memory needed, in mpi program. as finding data, provided them (directly or indirectly) (by master process, if master-slave model used). if indeed each mpi instance has "search" data processing, program unable find requires, should send suitable error message/status caller (or master process) .pmcd.

hello, what meaning of {$var} in php? example: $query = "update table set field = '{$var}'"; thx. {$var} "shields" variable name surrounding characters. example: $root = "stick"; echo "{$root}y"; # adjectify! will output "sticky", where: $root = "stick"; echo "$rooty"; # adjectify! no, kidding. will output nothing @ all, since variable $rooty doesn't exist. it allows use expressions more variable names, array indexing or property access.

i'd create simple visual effect display of rows of data on iphone/android/etc, seen in this example . the effect simple; it's 2 rectangles on top of each other, top 1 lighter bottom 1 , lighter-yet border-top. it: <style> .rowtop { background-color: #333; border-top: 1px solid #ccc; height: 25px; } .rowbottom { background-color: #000; height: 25px; } </style> <div class="row"> <div class="rowtop">&nbsp;</div> <div class="rowbottom">&nbsp;</div> </div> now i'd able place text , labels on top of this, again seen in the example . that's need help. i'd place text relative "row", row made of 2 divs, it's complicated. text has live on top of "rowtop" , "rowbottom" divs. i tried messing around third div labels , setting z-index couldn't wanted. i think can use background image instead of rowtop , rowbottom , make easy on myself, won...

i've got bit of chicken , egg. i need bind gridview set of database values. gridview dynamic , columns, cells created @ run time. as such, need re-bind grid on every postback in pre-init, init events after post back. however, data used populate grid uses value dropdown box on same page. such, value of dropdown not accessible through viewstate until after init event (i.e. selected index first item in list until after on init). how can access value of drop down in time rebind grid before pageload event? if gridview has same number of columns, have dynamic query generate column names aliases, , rebind gridview on dropdown change?

look @ profile pages of users have asked more 10 questions. (e.g., https://webapps.stackexchange.com/users/2496/tobeannounced ) now try skipping questions 10-20, or page 2 of questions have asked. the load new page instantaneous. how accomplished? simply loading questions when first page loaded additional pages called load fast? in other words, additional pages pre-loaded? using network tab of firebug firefox, can see http requests being made. turned on can see clicking next link fires off http request grabs next page of questions (i.e. not preloading questions initial page load). it's small request, small response, , server replies really quickly, why happens instantaneously.

i have advanced search on web page, how works follows. when search made, random results appear on content page, page included pagination, problem everytime visitor goes 1st page different results appear. possible use pagination this, or ordring random. i'm using query select * table order rand() limit 0,20; you should use seed mysql rand consistent results. in php $paginationrandseed = $_get['paginationrandseed']? ( (int) $_get['paginationrandseed'] ): rand() ; and in mysql use seed "select * table order rand(".$paginationrandseed.") limit 0,20" of course you'll need propagate initial seed in page requests. good luck, alin

i've been running simple debug tests against arrays, , noticed when var_dump() of array, output flagging element in array referenced variable. simple experiment, ran following code: $array = range(1,4); var_dump($array); echo '<br />'; foreach($array &$value) { } var_dump($array); echo '<br />'; $value2 = &$array[1]; var_dump($array); echo '<br />'; which gives following output: array(4) { [0]=> int(1) [1]=> int(2) [2]=> int(3) [3]=> int(4) } array(4) { [0]=> int(1) [1]=> int(2) [2]=> int(3) [3]=> ∫(4) } array(4) { [0]=> int(1) [1]=> ∫(2) [2]=> int(3) [3]=> ∫(4) } note ∫ symbol alongside element 3 , subsequently element 1. note entries don't show entry's datatype. following experimentation, don't see if var_dump scalar type, or objects or resources. if array contains string data, symbol & (and still show datatype), likewise float, boolean , object entries. t...

simple. when html page contains lot of small images take time have rendered, since each file needs requested separately. example, if have 500 32x32 avatar images want display, browser needs 500 requests 500 headers resulting in 500 responses headers. thus, lot of traffic. reduce amount of traffic, think better send files single request/response , have client script splitting of file separate images, placed wherever needed. thus, browser executes script, script requests image package, server returns package , script put images in it's proper locations. thus, 1 request/response instead of 500 requests/responses. has similar been created already? if so, whom? it called css-sprites, have big image images in grid pattern , css rules 1 want. check http://spritegen.website-performance.org/ http://csssprites.com/

i have requirement end user should not able go restricted page after logout/sign out. end user able browser button, visiting browser history or re-entering url in browser's address bar. basically, want end user should not able access restricted page in way after sign out. how can achieve best? can disable button javascript? you can , should not disable browser button or history. that's bad user experience. there javascript hacks, not reliable , not work when client has js disabled. your concrete problem requested page been loaded browser cache instead of straight server. harmless, indeed confusing enduser, because s/he incorrectly thinks it's coming server. you need instruct browser not cache all restricted jsp pages (and not logout page/action itself!). way browser forced request page server instead of cache , hence login checks on server executed. can using filter sets necessary response headers in dofilter() method: @webfilter public class noca...
