if open file reading, may define 1 or more state flags, example: ios::out ios::out | iso::app i read bitwise or, , how "merges" 2 bit sets, for example: 1010 | 0111 = 1111 now being said, not understand how works "behind scenes" when use method ifstream.open(filename, stateflaga | stateflagb | stateflagc) , on. can elaborate more on inner workings of these state flags , memory representation? edit: give more emphasis on trying understand (if helps), assume open method receive 1 or more state flags separate arguments in signature, , not delimited bitwise or, want understand how bitwise or works on these state flags produce different final state when combining several flags, , result allows me use 1 argument state flag or set of state flags. ie: ifstream.open(filename, stateflaga | stateflagb | stateflagc) and not ifstream.open(filename, stateflaga , stateflagb , stateflagc) if take gnu libstdc++ implementation , @ how these implemented,

i have groups field in mongodb database "groups" : "[\"5514efcc6970640f40150100\", \"5514efcc6970640f40160100\", \"5514efcc6970640f40170100\", \"5514efcc6970640f40180100\"] please suggest query check if field exist above database array. like modelname.find(:groups=> 5514efcc6970640f40150100) looks have string in groups , not array. string looks called inspect on array of bson objectids in ruby , stored stringified array in mongodb. the leading double quote here: ⬇ "groups" : "[\"5514efcc6970640f40150100\", ... ⬆ tells you have string. inside string have looks array of strings still string. if that's have think you're stuck regex searches (which slow), like: model.where(:groups => /"5514efcc6970640f40150100"/) that assumes groups strings consistently formed , stringified arrays of hexadecimal strings. if case i'd suggest fi

this has been posted before, couldn't find solution searching. i'm new html , css started ~1 week ago, if there solution explanation go long way rather modified code/solution. so attempting split div 2 columns 1 of 25% width , other 75% width. haven't started doing css yet hence why styling inline @ moment. general div of 100% width displays fine when try split 2 inner div's seems work list trying create displays correctly next column of 75% appears below div. why , there anyway fix it. <div style="width:100%;background:orange"> <div style = "text-align:center;width:25%;background-color:red;"> list <ul> <li> something</li> <li> something</li> <li> something</li> <li> something</li> <li> something</li> </ul> </div> <div style="width:75%;background:purple;">

how call angularjs page totally different, not mine, , caller page uses post form-data. there needed special web server setup on side, or can angular handle incoming post request totally without server side logic on side (so angular-page can served anywhere, simple file server dropbox)? you mean angular page angular page communication? angular runs in browser, want client client communication. have build around server yourself. easiest way use websockets. client sends message server -> server sends message target client -> client receives message or client sends message server -> server stores message , waits client pick -> client picks message server if mean page x calls angular page via post request. your angular page communicates server time. should not try catch post request page inside angular (you can't anyways), have catch on server , somehow load appropriate page angular logic kicks in. you cant catch post requests in browser, on serve

i wondering efficient way/best library parse cron expression , return list of time points in java. for example have cron expression, say, fire every minute in october 2010 , list/array of epoch times (or other date format) returned correspond times trigger fires. thanks you use org.quartz.cronexpression.getnextvalidtimeafter() . using method can iteratively many trigger times wish. you have decide starting point of iteration, current moment or epoch or smth else. and can parse string cron expression org.quartz.cronexpression using constructor cronexpression(string cronexpression) . edit: can find similar functionality in spring framework's cronsequencegenerator . both used in similar iterative fashion check 1 suits best regarding performance etc.

i have 2 .xls files. 1 of files has column named "customer id" witch contains 700 8 digit values such 11557096. other file has column named "requested for" includes 2000 values customer id plus / name such 11557096 - john doe. find rows on second file match customer id's on "customer id" column on "requested for" column. here simple filter example can start with. the set up sub button1_click() dim rws long, rng range, filtrng range rws = cells(rows.count, "a").end(xlup).row set rng = range(cells(2, 1), cells(rws, 2)) application.screenupdating = 0 rng.autofilter 1, range("d1") set filtrng = rng.offset(1) filtrng.copy sheets("sheet2").cells(rows.count, "a").end(xlup).offset(1, 0) activesheet.autofiltermode = 0 end sub the filter result paste next sheet. the sample workbook once have going can work on different sheets , different workbooks.

i'm testing tidy php add 'human' layout view of given html page once it's sent browser (it's generated in compressed form default), have problem. every <link> element rel attribute set stylesheet gets type="text/css" appended @ end. same goes <style> element, behaves in same fashion. <script> element gets type="text/javascript" appended. while it's fine me, filter these bits out, , know if there's option in tidy configuration (i've been reading option list in tidy website haven't found suggesting me such filtering) or must filtering manually like: $output = str_replace([" type=\"text/javascript\"", " type=\"text/css\""], ["", ""], tidy_parse_string($input, $options, "utf8")); is there better filtering procedure one?

i have coordinates of current location , trying find out how ne , sw corners current location on google maps using latlngbounds. i don't seem understand how implement latlngbounds api google has written here: https://developers.google.com/maps/documentation/business/mobile/android/reference/com/google/android/m4b/maps/model/latlngbounds if explain me latlngbounds , how use great. please let me know if need add more information clear up. thank you. a latlng point; latlngbounds rectangle. @ minimum, construct latlngbounds, need 2 latlngs: 1 southwest corner of rectangle, , 1 northeast corner of rectangle. given 2 points, other 2 points of rectangle trivially computed. its not clear question why need latlngbounds. should need if plan put imagery onto map, or draw type of rectangle. if want show marker or infobox don't need latlngbounds. if plan use groundoverlay show image centered upon latlng point, more complicated think. have use geolocation mappin

i new dart language. know more conventions programmers follow while developing in language. should encapsulate class members do, example in java? whenever create property of class, should make private , provide getters/setters? or there situations when should leave them public? if so, examples of these situations? in opinion, type annotations such string, int, etc. increase readability of code. serve documentation other developers reading/using code. programmer should not think value of type storing in variable right now. again, situations, require using var keyword when declaring variable? dmitry. thank you. thanks checking out dart! no need encapsulate class fields. dart creates implicit getters , setters you. if need compute field, can implement getter or setter manually. bonus: doesn't break consumers of api. example: class person { int age; } later, want calculate age: class person { datetime birthdate; int age => new datetime.now().di
