pan gesture / scrolling on web view not working on webview hosting jquery datatables table until click on table header done. meaning, user cannot scroll table , down , sideways, until presses table header (which sorts table). happens on non-jquery-tables js code – webview not scrollable. interesting thing note, when attach chrome debugger webview, scrolling starts work. i’ve tested same code on android chrome browser local , remote js code – , scrolling works. leads me think there’s kind of issue webview itself. thought might swipe gesture collision - there no swipe gesture defined (meaning web view standalone in activity , there no windows swipe to). any ideas? you should post code, android webview has many options, i'll start testing: webview.getsettings().setbuiltinzoomcontrols(true); also check javascript enable. hope helps

so have string of characters typically formatted this: " t e xt" bold character red. i want display these types of strings in richtextbox bold character being red. i have text in string variable , have location of red character (in string) in int variable. my solution is: get characters before red character get red character get characters after red character display characters before red character display red character (with foreground = brushes.red) display characters after red characters this i've got far: https://github.com/icebbyice/rapide/blob/master/rapide/spreadwindow.xaml.cs find: "//stackoverflow" (also, seperateoutputs not completed) i stopped there because thought there had more efficient way because changing content of rich text box (up 1000 content changes / 60 seconds). so, there better way this?

i'm trying write search query in linq. below condition. where (!string.isnullorempty(namewithinitials) && tb.namewithinitials.contains(namewithinitials)) && (!string.isnullorempty(studentregno) && tbsr.studentregistrationno.contains(studentregno)) && (!string.isnullorempty(nic) && tb.nic.contains(nic)) && (!string.isnullorempty(fullname) && tbi.name.contains(fullname)) it doesn't return values if pass single parameter. example if pass 'chamara' fullname doesn't return result if pass parameters @ once returns matching records. i need work when pass several parameters dynamically you using , ( && ) everywhere, if @ least 1 of these conditions false, where condition false. try using or conditions instead: where (string.isnullorempty(namewithinitials) || tb.namewithinitials.contains(namewithinitials)) && (string.isnullorempty(studentregno) || tbsr.studentregistrat...

i developing countdown timer app. user can register app , share own countdown timer; however, have problem here, how let user synchronize same countdown timer? use angular , nodejs + mongodb develop app. problem countdown timer running angularjs 1 user can see running timer, other people can't. should update every second number in database , query every second or running timer in backend? any suggestion ? i'd way: when timable action occurs server-side, store both start time and end time in database. upon page load, both numbers pulled client, figures out delta , starts own local countdown. gui can optionally show server-side end time, "time of record."

is possible define default trait in factorygirl? if define factory (where both question_response belongs_to question): factory :question_response question work_history trait :open question { factorygirl.create :question, question_type: 'open' } end end when factorygirl.create :question_response, :open first create default question , create inside trait, unnecessary operation. ideally i'd this: factory :question_response work_history trait :default question { factorygirl.create :question, question_type: 'yes_no' } end trait :open question { factorygirl.create :question, question_type: 'open' } end end and doing factorygirl.create :question use default trait, doesn't seem possible. when factorygirl.create :question_response, :open first create default question , create inside trait it's not true. if specify trait question , overwrite factory behavior before creation not create default ques...

so have create socket , using function socket.bind() , keep on getting following error: 1 usage of each socket address (protocol/network address/port) permitted here code: import socket s = socket.socket() host = socket.gethostname() port = 12345 s.bind((host, port)) s.listen(5) while true: c , addr = s.accept() print('thank connecting to', addr) c.send('hello , connecting') c.close() the port / ip combination bound already. can not bind again. should check if other instance of program still running. if not, use other port.
