if mvvm data binding , cannot view.dothis() , otherwise it's mvp, how invoke actions on views? suppose have view has snackbar . view controlled viewmodel . how viewmodel supposed show snackbar without going snackbar.show() ? in mvvm, viewmodel captures state of view. view observes viewmodel changes , updates itself. thus, communication between view & viewmodel happens through change of values (as against method calls in mvp). since snackbar global behaviour (like toast), can implemented @ activity/fragment level. so, can make messagehelper interface , pass viewmodel dependency. activity implement , display snackbar . example: itemviewmodel consumes interface activity base class implements interface however, possible there view specific behaviour cannot implemented @ activity level. such cases, can make use of databinding.observable trigger event. example, lets want animate particular view. can create bindingadapter @bindingadapter({"shaket

the signature of modifyioref straightforward enough: modifyioref :: ioref -> (a -> a) -> io () unfortunately, not thread safe. there alternative adresses issue: atomicmodifyioref :: ioref -> (a -> (a,b)) -> io b what differences between these 2 functions? how supposed use b parameter when modifying ioref might read thread? as stated in comment, without concurrency you'd able write like modifyandreturn ref f = old <- readioref ref let !(new, r) = f old writeioref r new return r but in concurrent context, else change reference between read , write.

i building exam datesheet. i'm having issues in finding conflicts between time.. i have list of strings stores time intervals like- list<string> times = new list<string>(); times.add("6:00 pm 9:00 pm"); times.add("10:00 1:00 pm"); now suppose, if want add below time list, first want check not conflict time there. so, in below case, should not added. if(notconflict("5:00 pm 7:00 pm")) times.add("5:00 pm 7:00 pm"); but following can added since there no conflict. if(notconflict("2:00 pm 5:00 pm")) times.add("2:00 pm 5:00 pm"); i cannot use datetime here because old system , time being stored above. , being used @ many places. this should work: private static tuple<datetime, datetime> parsedate(string datetimes) { var split = datetimes.split(new[] { " " }, stringsplitoptions.none); var time1 = datetime.parseexact(split[0], "h:mm tt",

i wrote query difficult read , im afraid efficiency might bad. can query written more efficiently in terms of matching consumerid's each table consumerdata.consumerid? select consumerdata.consumerid, signupdate, city, state, year(dob), topaffiliate, activestatus, lastuseddate, (select sum(achload.transactionamount) achload achload.consumerid = consumerdata.consumerid) total_ach, (select sum(billpay.transactionamount) billpay billpay.consumerid = consumerdata.consumerid) bill_pay, (select sum(recharge.transactionamount) recharge recharge.consumerid = consumerdata.consumerid) revenue, (select count(cash.consumerid) cash cash.consumerid = consumerdata.consumerid) cash__txns, (select sum(moneytransfer.transactionamount) moneytransfer moneytransfer.consumerid = consumerdata.consumerid) transfer, (select sum(moneytransfer.commissionfeeamount) moneytransfer moneytransfer.consumerid = tbl_accounts_consumerdata.consumerid) commission_fee, (select count(interchangetransactio

window.addeventlistener("contextmenu", function(e) { e.preventdefault(); return false; }); while above code overrides "right click menu" intended, seems, opera have right-click gestures, when hold down "right-click" button, , swipe left, browser goes back in game "right click" utilised, results in unintentional back/forward events repeatedly i'm looking programmatic solution fix issue, there events fired can caught , prevented? ps. i'm aware there old questions try solve same issue: how disable opera mouse gestures? - if there still no programmatic solution issue, add warning game nudge people use chrome instead why not this? var w = window; $(w).mousedown(function () { if (w.opera || navigator.useragent.match(/opera|opr\//)) $(this).bind("mousemove", function () { return false; }); } }); note: right click captured mousedown.

i using firebase cloud messaging send message app. thinking using send data app server, not sure if there advantage in using on classic http rest api. i better of sticking classic http api send message devices server, or using firebase upstream message better in ways? the "official" advantage of upstream fcm message, @ least on android, no additional network connection needed, resulting in performance , battery-saving benefits, , possibly easier implementation. depending on how authenticate users see potential simplification in case of fcm, may not need separate authentication mechanism compared rest api.

what trying accomplish run load of 6000 vusers on web page. cannot figure out how call load controllers. cannot find clear documentation next call load tests , assign work multiple load controllers. since internal company. cannot use vsts load controllers. based on these pages https://blogs.msdn.microsoft.com/edwinh/2016/04/21/guide-to-get-started-with-visual-studio-web-load-testing-and-automation-2/ https://msdn.microsoft.com/library/dn250793(v=vs.120).aspx#anchor_3 you can install load controllers on other servers. have done this. i connected load controller in load settings file. but, how attached 2 or more load controllers? i tried build test using solution test settings file. don't see way attach many load controllers. if run test build runs.. have no info see if ran test. load tests need more resources can run directly visual studio can use controller , agents. 1 controller can used load test can control many agents. see here brief idea of how works.
