i'm using gson project. in particular use code generate json strings: gson gs = new gson(); jsonobject cmdobj = new jsonobject(); cmdobj.addproperty("cmd", cmd); cmdobj.add("arg", args); string cmdstr = cmdobj.tostring(); which produces like: {"cmd":"handshake","arg":{"protocol":"syncmanager","servername":"12345678910"}} then on client machine reads json data: string cmdstr = readcommand(this.is); gson gs = new gson(); jsonobject jsobj = gs.fromjson(cmdstr, jsonobject.class); jsonelement cmd = jsobj.get("cmd"); jsonobject args = jsobj.get("arg").getasjsonobject(); the problem jsobj should contain parsed object doesn't contain ( if tostring() prints {} ). why this? want jsonobject tree had on other side, not object serialization. clues? jsonobject jsobj = new gson().fromjson(cmdstr...

this visual studio 2008. has static class extensions. public class dummy { public readonly int x; public dummy(int x) { this.x = x; } public override string tostring() { return x.tostring(); } } [obsolete("do not use", true)] public static class extensions { public static int squared(this dummy dummy) { return dummy.x * dummy.x; } } class program { static void main(string[] args) { var d = new dummy(42); console.writeline(string.format("{0}^2={1}", d, d.squared())); } } that repros in vs2010 well. looks bug. i'll entered in database. you can work around bug putting attribute on actual method. thanks report!

i working on document based application. when opening saved file, load in nsmanagedobjectcontext view controller. view controller needs observe changed on property "depth" on objects of type. when view controller gets context, gets these objects, adds observer of value on each, , keeps them in array keep track. whenever core data sends contextdidchange notification, add created objects array after observing them. deleted objects, remove view controller observer , remove them array. this works great until close document , reopen it. when happens, objects added array. observation works fine. however, second first "nsmanagedobjectcontextobjectsdidchangenotification" comes in, of nsmanagedobjects somehow no longer in array set up. on delete, crash telling me can't remove observer that's not observer. it's strange. why nsmanagedobjets gone? don't release array or funny business @ all. when close document , reopen it, getting...

are there decent articles online explain in detail how conventions work in ef 4.1? there article linked scott gu's blog, dated 2010, think in ctp 4. not sure if conventions have beem modified since then. don't understand how works. example how know use table skilltype if have code (what for?): public dbset<skilltype> skilltypes { get; set; } this 1 of confusions, there foreign keys, primary keys, etc. need familiarise myself these conventions goof articles can read please let me know. did google , couldn't solid , concrete. there no real walkthrough. can find basic description of conventions in msdn. my answer on msdn forum posts links conventions. there big change in conventions since ctp5. first of cannot add custom conventions more - feature removed final version. if define dbset in example not job convention define table. there mechanism (probably using reflection) finds defined sets in contexts , starts mapping generation.

i'm working on branch , bound algorithm traveling salesman problem , i've run little hitch. i'm using pretty standard queue nodes representing subsets of vertices (paths). i'm pretty sure have whole thing worked out, @ moment have public class queue, , underneath private class node, of properties: current path, lower bound, etc. however, in main program, initialize queue of nodes , create 2 starting nodes, error "node cannot resolved type". assumed because within queue class , not accessible main program, when move out, errors everywhere else on items connected node. i hope makes sense, i'm not sure how else explain it, else seems fine. here's snippet of code clarification: `public class queue<item> implements iterable<item> { private int n; // number of elements on queue private node first; // beginning of queue private node last; // end of queue // helper linked list class public class node { ...

to gae+html5 gurus out there :) when user logs on gae hosted application, credentials stored locally in cookie (correct?). after cookie expires (e.g. if users hits logout on browser tab), no login_required protected methods work. regular webapp require re-authentication next time user navigates login_protected url automatically redirecting login screen. what right way cached webapp handling this? my test simple login_protected page accessed chrome , ios browser. it's cached , accessible offline expected. then, (while online) , after authentication expires, server log shows 302 response followed 200 response of authentication dialog page, of course no authentication happens. thanks! if using google authentication provide access page . means if logged in 1 of other google services. cookie still exists in browser. login_required assume logged on based on cookie. seeing redirection google's page that's 302. if want can manage sessions on own , chec...

i made custom sessionstatestore provider, dependencies not resolving. used unity di. i googled lot problem , got useful hints, still can't right. the providers constructed , managed framework, , there no opportunity intercept construction provide additional dependency injection override initialize() method in custom provider, , dependency injection there there's similar problem , decent solution here , here (structuremap, not unity), can't right. please help. thanks. providers painful things . there's no nice way address problem, practical way handle provider composition root - in other words, if entry point of application. within provider can compose of services. if use di container (like unity) can store container instance in httpcontext , there compose object graph within provider.

i have callback function function loops through comments of article in blog. tried switch "threaded/nested" comments , therefore extended callback function. far works, can't rid of feeling, didn't write according best php-practice (and performance). i use css framework , have math .span-xy classes assign single comments. start input value global constant , output eg. span-12 parent comment. have reduce/rise value per +/- (int) 1 every level of nesting. came building arrays, counting them, iterating through , building temp arrays every comment. question: there easier way around this? <!-- final html mark-up output: list of comments (threaded/nested) --> <ul> <li id="1" class="push-<?php echo $push; ?> span-<?php echo $span; ?>">comment - parent</li> <li id="2">comment - child of #1 <ul class="children"> <li id="3">comment -...

i having trouble writing regular expression in c#; purpose extract words start '@' given string can stored in type of data structure. if string "the quick @brown fox jumps on lazy @dog", i'd array contains 2 elements: brown , dog. needs handle edge cases properly. example, if it's @@brown, should still produce 'brown' not '@brown'. something c#: string quick = "the quick @brown fox jumps on lazy @dog @@dog"; matchcollection results = regex.matches(quick, "@\\w+"); foreach (match m in results) { literal1.text += m.value.replace("@", ""); } takes care of edge case too. (@@dog => dog)
