i trying make gridview control in asp.net multi sort based on if user pressed ctrl key when trying sort clicking on column name. problem when using firefox, if click on column name ctrl key pressed, browser tries open "javascript:__dopostback('ctl00$contentpla..." link in new tab. ie , chrome both don't unless link real link. is there way can prevent firefox opening link in new tab , still cause page postback normally? thanks. you need capture event of ctrl key being pushed down, using document.onkeydown. in event handler, check if 'ctrl' (key code 17) pressed, follows: function document_keydown(e) { var keyid = (window.event) ? event.keycode : e.keycode; if (keyid == 17) { ctrldown = true; } } here, i'm setting 'ctrldown' variable true. for onkeyup event, can exact opposite: function document_keyup(e) { var keyid = (window.event) ? event.keycode : e.keycode; if (keyid == 17) { ...

is there way collect usage metrics of asp.net web service google analytics collect usage metrics of web site. without implementing own database tables or code. i don't need collect huge amount of information collected google analytics, simple information, number of calls , distribution on time. if no external tool can used, how process request web service extract information request location, request source, , other information collected. if you're hosting service in iis web server (which persume do), can check iis web server application log, requests written file. open *.log file , copy contents excel, , use excel pivot/group/filter/sort data present count (the number of requests) web service in meanigful manner.

i have simple piece of code public actionresult listtogrid(string field, string direction) { _model.mylist = _repo.list(); } to sort, can : _model.mylist = _employeeservice.list().orderby(x => x.firstname).tolist<employee>(); but i'd use "as field" name receive (field) in argument , direction received too. thanks, you use reflection, rather slow. efficient declare delegate use in sort, , assign function depending on string: func<employee,string> order; switch (field) { case "firstname": order = x => x.fristname; case "lastname": order = x => x.lastname; } for direction think it's best use separate codes: var list = _employeeservice.list(); ienumerable<employee> sorted; if (direction == "ascending") { sorted = list.orderby(order); } else { sorted = list.orderbydescending(order); } _model.list = sorted.tolist<employee>();

in web app i've created in zend framework, i'm creating new database every new client registers. query of course rather heavy , time consuming since need create database, create 10 tables , put data in tables. we using 1 large sql file read in , exec(). after queries, mysql connection in zf, need insert new record in 1 of tables have been created in previous step. this fails: when first query isn't finished yet , try insert data in on of tables being created, error "table xxxx doesn't exist". all happens in fraction of second, cannot find way "wait" first large query have finished. putting sleep(2) command before second statement solved problem, that's not way want play. also, cannot use transaction since using create database , other statements cannot used transactions. one database per client can of worms want eliminate before gets out of hand. use single database client_id field in each table indicate client record bel...

i trying make link create new nested resource in rails 3 application, can't figure out. syntax link new nested resource solution: make sure have resources nested in routes file. resources :books resources :chapters end then in view script can call this: <%= link_to 'new chapter', new_book_chapter_path(@book) %> the rails guide on routing quite helpful. note: if message couldn't find book without id , problem isn't link, it's code in controller. def new @book = book.find(params[:book_id]) #instead of :id @chapter = @book.chapter.new respond_with(@chapter) end make changes in routes as map.resources :books |book| book.resources :chapters end and use this link_to new_book_chapter_path(@book) you can use link understand concept better nested routes

i created 1 web application want store past logged user name list comparing new users going login. how using servletcontext ? or there other way? in jsf, application scoped managed beans stored in servletcontext. so, create , declare application scoped managed bean , put list in there. however, there better ways particular functional requirement yet unclear in question. @ least, implementing httpsessionlistener or httpsessionbindinglistener better idea since logins coupled httpsession . here several examples: how invalidate session when user logs in twice? how check who's online?

i'm having design problem don't know how overcome in java. want override method called parent constructor. here simple example of problem: public class parent { public parent(){ a(); } public void a() { // code return; } } public class child extends parent { public child() { super(); } public void a() { super.a(); // more code return; } } i know child class wont initialized until parent constructed therefore childs a() method wont called. correct design overcome problem? the child override called - child constructor won't have executed yet, unless it's designed invoked on partially initialized object, have problem. best approach not call virtual methods in contructors . is problem. in control of both classes? can redesign avoid problem in first place?

can make video "stretch" width & height of video element? apparentlyby default, video gets scaled & fitted inside video element, proportionally. thanks from the spec <video> : video content should rendered inside element's playback area such video content shown centered in playback area @ largest possible size fits within it, video content's aspect ratio being preserved. thus, if aspect ratio of playback area not match aspect ratio of video, video shown letterboxed or pillarboxed. areas of element's playback area not contain video represent nothing. there no provisions stretching video instead of letterboxing it. because stretching gives bad user experience, , of time not intended. images stretched fit default, , because of that, see lots of images badly distorted online, due simple mistake in specifying height , width. you can achieve stretched effect using css 3 transforms , though aren't standardized or implemented in ...

os figured out how use -mthumb , -mno-thumb compiler flag , more or less understand it's doing. but -mthumb-interlinking flag doing? when needed, , set whole project if set 'compile thumb' in project settings? thanks info! open terminal , type man gcc do mean -mthumb-interwork ? -mthumb-interwork generate code supports calling between arm , thumb instruction sets. without option 2 instruction sets cannot reliably used inside 1 program. default -mno-thumb-interwork, since larger code generated when -mthumb-interwork specified. if related build configuration, should able set separately each configuration "such release or debug". why want change these settings? know using thumb instructions save memory save enough matter in case?

when using raw_input in loop, until character typed (say 'a' ), how can print inputs before that, in reverse order, without storing inputs in data structure? using string simple: def foo(): x = raw_input("enter character: ") string = "" while not (str(x) == "a"): string = str(x) + "\n" + string x = raw_input("enter character: ") print string.strip() but how same without string? this not practical approach, since asked it: def getchar(): char = raw_input("enter character: ") if char != 'a': getchar() print char getchar() of course means i'm using "hidden" data structures, local namespace , call stack.

i have question in mind. convention, unix associates file descriptor 0, 1, 2 stdin, stdout, stderr on every process. file, e.g. pointed stdin, shared different processes? if shared, when open 2 shells type inputs these 2 shells, how os doing manage shared file? overview the descriptor table per-process, it's possible every process in system have different file open in every descriptor table slot but in practice it's bit more complex. if 2 processes open file independently, each have separate access file, own read , write pointers, , interact if both write same file. but when process fork(2)'s, parent , child's descriptors point same file table entry, , share single position in file. enables unix processes share access input stream without needing aware of situation. three tables access files chained through 3 important tables in unix. descriptor table per-process , points file table . think of file table open file table . there third table, calle...
