i have winforms c# app displays tabular data db gridview control. i need programmatically add final column tickbox each row, in order find out rows have been ticked form current view. how go doing that, tickbox column not exist in db? you add column directly datasource before binding datagridview. supposing using datatable datacolumn dc = table.columns.add("select", typeof(bool)); dc.defaultvalue = false; grid.datasource = dt; another method define datagridviewcheckboxcolumn() , append current column list checkcol = new datagridviewcheckboxcolumn(); checkcol.headertext = "select"; checkcol.width = 80; checkcol.readonly = false; grid.columns.add(checkcol);

so problem having appears bug occurs on linux. i'm trying have swing app record when key pressed down, detect when key released. shouldn't in issue because keylistener supposed handle me. the problem when hold key down lots of repeated keypressed()/keyreleased() events instead of single keypressed(). have solution or workaround knowing when key released on linux? thank you. so problem having appears bug occurs on linux yes linux problem. on windows when key held down multiple keypressed events single keyreleased event. this question asked , i've never seen solution. but think basis of solution use timer. when key pressed start timer. when keypressed restart timer. long timer interval greater repeat rate of key board timer continually reset when key held down. when keypresses stop being generated timer fire assume key has been released. implies have delay in processing keyreleased.

i'm trying create chrome packaged app complicated web app. i'm getting error: refused execute inline event handler because violates following content security policy directive: "default-src 'self' chrome-extension-resource:". note 'script-src' not explicitly set, 'default-src' used fallback. how explicitly set policy in manifest.json? i've tried things like: "content_security_policy": "default-src 'inline'; script-src 'inline'" but still same error message. syntax wrong, or error red herring? you can't loosen default csp in packaged app. if you're doing <button id="foo" onclick="dosomething()"> should instead include separate js file in html document.queryselector("#foo").onclick = dosomething; in onload handler. comply csp , make app more resistant xss attacks.

i'm fixing :active states of buttons on mobile page so: $('body').on('touchstart', 'a', function (e) { $(this).addclass("active"); }).on('touchend touchcancel click', 'a', function (e) { $(this).removeclass("active"); }); this delegation/bubbling approach works great, because i'm doing lots of dynamic page manipulation , don't want have re-apply hack. however, have additional code this: $('a#myanchor').click(function(e){ e.preventdefault(); // return false; }); this of course prevents first block working :( there elegant solution this? i know can re-apply hack #myanchor , that's ugly. is there way prevent clicking <a> causing navigation, allowing click event still propagate dom? bonus: can prevent other explicit click handlers attached #myanchor firing, still allow propagation dom? you've sorted now, it's annoying seeing unanswered quest

i have employee table foreign key dno refers dnumber in department table. in department table there foreign key mgr_ssn refers ssn in employee table. i created table using alter table employee add foreign key (dno) references department(dnumber) on delete restrict on update cascade; (both dno , mgr_ssn not null) but confused how insert data, because violates referential integrity constraint, suggestion? thank :) foreign keys not given "not null" constraint. if there new employee has not been assigned dept. or new dept no manager. still, problem should use " deferrable " property of oracle constraints. means, constraint checked @ commit point only. can insert dno , empnos first, commit later. @ point there no constraint viokation fk exists. alter table employee add foreign key (dno) references department(dnumber) deferred deferrable; --do same dept then, insert emp (...) insert dept(...) commit;

i trying read element can later use id of element. using below code first webelement. throws following in console: "[org.openqa.selenium.remote.remotewebelement@f76d0bdd -> unknown locator]" webelement ele = driver.switchto().activeelement(); system.out.println("webelement :"+ele); you seeing because asking code print ele.tostring() . which, according source, going give exact message see: https://code.google.com/p/selenium/source/browse/java/client/src/org/openqa/selenium/remote/remotewebelement.java#375 specifically: public string tostring() { if (foundby == null) { return string.format("[%s -> unknown locator]", super.tostring()); } return string.format("[%s]", foundby); } it says 'unknown locator' because 1 isn't explicitly set setfoundby . so, suggest if want id of element, use: ele.getattribute("id");

asp.net c# mvc 4 code first application - in visual studio 2012 express, sql server 2012 express. i have places object. output name of places in list - check box next each. i logged in users select places - , have saved. later can login , see them again, appropriate check boxes selected. what best approach? i'm new mvc , not sure of best practice here. thanks update the below checkboxlistfor helper worked great, though wasn't obvious how process user selection (it returns list of ids). i created below take list of ids - convert list of objects, , add selectecities list in view model. select checkboxes user selected before page posted: public actionresult examples(postedcities postedcities) { // viewmodel citiesviewmodel cvm = new citiesviewmodel(); // create list of cities list<city> cities = new list<city>{ new city { id = 1, name = "london"}, new city { id = 2, name = "saigon"}, new city { id = 3, name = "new

here simple c++ snippet: int x1 = 10, x2=20, y1=132, y2=12, minx, miny, maxx, maxy; x1<=x2 ? minx=x1,maxx=x2 : minx=x2,maxx=x1; y1<=y2 ? miny=y1,maxy=y2 : miny=y2,maxy=y1; cout<<"minx="<<minx<<"\n"; cout<<"maxx="<<maxx<<"\n"; cout<<"miny="<<miny<<"\n"; cout<<"maxy="<<maxy<<"\n"; i thought result should be: minx=10 maxx=20 miny=12 maxy=132 but result is: minx=10 maxx=10 miny=12 maxy=132 could give explanation why maxx not 20? thanks. due operator precedence, expression parsed this: (x1<=x2 ? minx=x1,maxx=x2 : minx=x2), maxx=x1; you can solve with: (x1<=x2) ? (minx=x1,maxx=x2) : (minx=x2, maxx=x1); and don't need first 2 pairs of parentheses. also check question .

when using matlab through gui, can interrupt computation pressing ctrl - c . is there way same programmatically when using matlab through the matlab engine c api ? on unix systems there solution: send sigint signal . not kill matlab. it'll interrupt computation. looking solution works on windows. clarifications (seeing answerer misunderstood): i looking way interrupt matlab calculation, without having control on matlab code being run. i'm looking programmatic equivalent of pressing ctrl - c in @ matlab command window, on windows systems. a mathematica-matlab interface : need forward interrupts mathematica matlab. mentioned above, have working implementation on unix; question how on windows. one way make matlab engine session visible, prior executing long computations. way if want interrupt execution, bring visible command window focus , hit ctrl-c. this can done using engsetvisible function here quick example tried using matlab com automation

i reconized numpy can link blas, , thought of why not using gpu accelerated blas library. did use so? update (2014-05-22) amd has produced beta release of amd core math library (acml) version 6.0 can offload fft , blas functions gpu using clmath internally. announcement here: acml beta 6.0 release leverages power of heterogeneous compute . caveat here input data must transferred cpu gpu , output data returned cpu on each blas or fft call. therefore, amd has bunch of scripts tuning when problem large enough acml use gpu instead of cpu. for sake of completeness, i'll mention nvidia supports similar functionality nvblas library relies on cublas , cuda won't work on nvidia gpus. original answer unfortunately, amd's gpu accelerate blas library cannot directly link numpy or other application expecting standard cpu-based blas library. reason existing gpu blas libraries require 1 first copy matrices gpu before calling blas functions. requires modify n

in python documentation itertools provides following "recipe" advancing iterator n steps: def consume(iterator, n): "advance iterator n-steps ahead. if n none, consume entirely." # use functions consume iterators @ c speed. if n none: # feed entire iterator zero-length deque collections.deque(iterator, maxlen=0) else: # advance empty slice starting @ position n next(islice(iterator, n, n), none) i'm wondering why recipe fundamentally different (aside handling of consuming whole iterator): def other_consume(iterable, n): in xrange(n): next(iterable, none) i used timeit confirm that, expected, above approach slower. what's going on in recipe allows superior performance? uses islice , looking @ islice , appears doing fundamentally same thing code above: def islice(iterable, *args): s = slice(*args) = iter(xrange(s.start or 0, s.stop or sys.maxint, s.step or 1)) nexti = next(i

as understand, update object couchdb. have send whole object since "inserting" new revision same id. neat , works quite well. but have problem, i'm not sure how should handle that. have object can't sent user completely. have hide informations such password hash. the data sent client, revision sent too. when try update object have 1 problem. since data missing, update erase attributes missing user. that said, easiest way have object couchdb, check if id , rev matches. if match, merge object missing attributes. work pretty , can support deleting attributes too. then using technique, add objects cache reduce time query frequent objects database. if object can updated, clear cache id. if object newer, i'll have handle error or merge object. is there better "good way" handle problem? edit after thinking during night, think found much better solution. instead of having username , password inside profile. i'll separate identification obje
