i have third-party library (mogre), in struct (vector3). add overload '+' operator (no override needed) type not sure how. i cannot use extension methods operator want extend; class not sealed not partial either, if try , define again new operator overload conflicts. is possible extend type this? best way it? you cannot add operator overload third-party type -- class don't have ability edit. operator overloads must defined inside type operate on (at least 1 of args). since it's not type, can't edit it, , struct s cannot extended. but, if non- sealed class , you'd have sub-class, ruin point because you'd have use subclass , not superclass operator, since can't define operator overload between base types... public class { public int x { get; set; } } public class b : { public static operator + (a first, second) { // won't compile because either first or second must type b... } } you overload between i...

i want make mobile version of website (you know, .m in url). how done, , different regular website? can still make website in html/css/javascript, or need additional tools mobile sites? final question - there difference viewing mobile website on android phone versus iphone? thanks. how done? in same way websites, html/css/js , bit more. what different regular website? basically not only: the display size biggest (or in case, smaller) difference, have take care of small displays , viewports. the user interact finger , not mouse, clickable area must bigger. can still make website in html/css/javascript, or need additional tools mobile sites? yes can (and should) use html/css/js check different video/audio tags on webkit mobile. is there difference viewing mobile website on android phone versus iphone? both come webkit have small differences (like touch events) websites differences minimal.

i'm writing application connects twitter , uses oauth api, issue storing consumer_key , consumer_key_secret how can safely store these values they're difficult user still have ability use them within application? i've had storing them within pyc , encrypting them suggestions far, i'm open other ideas. an alternative drm (which describing) proxy secured interaction through server application on own, controlled machine. since you're using oauth, can use same authentication credentials against own server connecting directly twitter. the advantage approach there no private key disclosure; don't share private key consumers, since that's stored on remote server cannot read, , consumers don't share passwords (instead, oauth token ties particular login specific service).

i have condition way construct string (finalvalue) based on number of non null values in input. wondering if ok on load setter method string (finalvalue) 1 diff no of parameters , call them based on values get? bad programming practice? public void setfinalstring(string a){ this.finalstring = a; } public void setfinalstring(string a, string b){ this.finalstring = + " --f " + b; } or can have method construct finalstring based on inputs , invoke setter (no overloading here) finalstring. pls tell me ok on load setters , suggest better approach? thanks yes, bad approach, setter supposed set passed parameter encapsulated private ivar. the other logic should somewhere else not in setter, although accepted have restrictions when set parameter in setter i.e. public setage(int age) { if (age >= 0) this.age = age; else this.age = 0; } that logic setter should have, should never receive more value assigning ivar.

i'm starting new google app engine application , considering 2 frameworks: flask , webapp2 . i'm rather satisfied built-in webapp framework i've used previous app engine application, think webapp2 better , won't have problems it. however, there lot of reviews of flask, approach , things i've read far in documentation , want try out. i'm bit concerned limitations can face down road flask. so, question - do know problems, performance issues, limitations (e.g. routing system, built-in authorization mechanism, etc.) flask bring google app engine application? "problem" mean can't work around in several lines of code (or reasonable amount of code , efforts) or impossible. and follow-up question: there killer-features in flask think can blow mind , make me use despite problems can face? disclaimer: i'm author of tipfy , webapp2. a big advantage of sticking webapp (or natural evolution, webapp2) don't have create own version...

ok, i'm developing web app has begun more ajaxified. read blog talked javascript hijacking , , i'm little confused when it's problem. want clarification question 1: problem/vulnerability? if site returns json data 'get' request has sensitive information information can wrong hands. i use asp.net mvc , method returns json requires explicitly allow json requests. i'm guessing trying save uninitiated security vulnerability. question 2: hijacking occur sniffing/reading response it's being sent through internet? ssl mitigate attack? question 3: led me ask question myself. if i'm storing page state in local javascript object(s) of page, can hijack data(other logged in user)? question 4: can safely mitigate against this vulnerability returning json 'post' request? the post linked talking csrf & xss (see comment on question), in context: is problem/vulnerabiliy ("if site returns json data 'get' re...

so have 2 tables: courses: -course_id (primary key) -course_code -title sections: -section_id (primary key) -course_id (foreign key) -day each course has number of sections belong it. let's use example. the tables: course_id course_code title 1 abc title1 2 bbc title2 section_id course_id day 1 1 monday 2 1 tuesday 3 2 monday 4 2 monday i want able run query asks courses give me ones of sections fit criteria. in case, let's want see "all courses have of sections on monday". desired output be: course_id course_code title section_id day 2 bbc title2 3 monday 2 bbc title2 4 monday notice how entry (2, abc, title1, 1, monday) omitted? can't seem think of way this. in advance! try this: select * courses c1 ...

i have function that, argument sake, has 2 lines of code. line line b both lines calls third party web service work. appears though service call on line b contingent on being called (time-wise) after call line a. works fine in non-threaded environment application threading lots (potentially 100) of these calls. the problem threading, believe, context switching between threads causing enough time (a small amount of time) elapse between call on line , call on line b it's causing call on line b throw custom soap exception. my knowledge of threading doesn't extend situation this. there anyway make sure call on line b happens after call on line without thread context switching occurring in between? if need these lines called can lock them, meaning nothing else enter section until complete: lock(lck) { line line b } however, may cause problems if 100 threads doing - lose parallelism. in fact, whatever do, if general requirement, lose degree of paralle...

i'm working asp.net (2.0), , want generate group of radio buttons data source. simple enough using radiobuttonlist, want text associated each radio button have more formatting...in particular, of text should regular weight, bold. doesn't seem match radiobuttonlist. using repeater, can create single radiobutton each item in dataset, give them same groupname, , they'll work correctly on client side...but when form submitted, it's not clear me how discover button selected (server side). unlike radiobuttonlist, don't have single containing object can ask selected item from. we use bit more interactive, posting information server on radio button click, we'd avoid postbacks if possible. am missing simple? put radiobutton's in panel, iterate control collection of panel foreach (control ctrl in panel1.controls) { if (ctrl.gettype().name == "radiobutton") { if (((radiobutton)ctrl).checked) ...
