i using jquery easyui treegrid on project. i have tree loaded initial data. afterwards, need insert new rows on tree when user clicks "add" button. add click handler has code , working expected: var row = $treegrid.treegrid('getselected'); if (row) { var obj = { id: "x" + ++maxid, code: "x" + maxid, amount: 2 }; $treegrid.treegrid('insert', { after: row.id, data: obj }); $("#txtresult").text("added new row: " + obj.id); } however afterwards when check children of row (where new child added), not include newly added row. i have setup jsfiddle demonstrate issue. reproduce it: select row @ 2nd level , click add child. new row added per code above. "row added" message displayed below buttons. select parent , click "show children" button. children count of selected row shown below buttons. after inserting row, ha...

first off, clear confusion, 'module based program intelligent linking' mean having adapter class intelligently inherit individual header files through 'plug-n-play' type system. system needs consist of simple folder called example 'modules', , all user needs activate module drag , drop header , source file of module folder. believe need utilize scripting language generate required text, such #include s, in adapter file. not know dynamic link libraries, prefer use them if possible (they need produce same effect of course). for example, lets have main here: moduleadapter->initialize(); while (true) { moduleadapter->update(); moduleadapter->render(); } moduleadapter->release(); this loop should able pass update , render function calls all of linked modules. next, example empty module file called 'module0.h', have this: class module0 { public: void initialize(); void update(); void render(); void releas...

i've been using git version control , github publishing code little while now. i'm getting comfortable interface , find helpful. however, i'm bit torn situation. i'm student using school computers , personal computer write code. i have work on application multiple computers. in middle of writing code when period ends , need leave. feels wrong push code github sync remote branch pc when home (this means that'd i'd have daily pushes github.) however, correct usage? if not, tool should use? want sync multiple workspaces code incorrect , buggy. it's ok push target work in progress branch. later on can ammend or squash history of branch before merging other main branches. take @ this: https://git-scm.com/book/es/v2/git-tools-rewriting-history

if call 1 lambda function 1 request, within function, there 3 calls made different functions count 4 calls or 1 call since based on 1 request? so if count 4 (from economic stand point) wouldnt better if 1 writes 1 long function instead of many small functions, despite being ill advised design pattern stand point? every invocation of lambda function counts. doesn't matter whether call console, cli, event source, or lambda function count invocation. personally, focus on writing lambda functions in way makes sense , allowed me use them effectively. if find costs factor later, can adjust then.

i'm thinking of writing application when running keeps track of websites visit , connections make. browser history, want in way utilizes network concepts. i have rudimentary understanding of http, able listen in on http requests browser , automatically pull information whenever request made? if can give me suggestion or outline of how can done, can research on implementing it, helpful! i'm thinking of implementing in python, , operating system ubuntu thank much. you implementing proxy . in case, basically, agent sits between browser , internet. proxy receive request client, then, send remote server, remote server may reply , you'll have send server response client. to retrieve informations wanting, reading http rfc helpful.

currently working on migrating bt2006 r2 (vs2005) bt2013 r2 (vs2013). tried below twp approaches. approach i: first, open bt2006 r2 project in (vs2010)[bt2010] [intermediate] then upgrade bt2010 project bt2013 r2 (opening in vs2013 project). it's work fine. there no issue on that. approach ii: directly open bt2006r2 project solution file in vs2013 (without intermediate version) getting below error error migrating project user file. element biztalk beneath element visualstudioproject unrecognized. i tried remove project user file , migrate bt2013 r2. still same error occurred. so means, can't direct migration bt2006 r2 bt2013 r2? do need first approach above? put way, if direct upgrade not work, have use intermediate step. that's it. so, yes, must follow approach 1.

is byte code intermediate form of code between assembly code , machine code? , bytecode same object code? this think - high level language->assembly language->machine code/object code (0s , 1s. different different cpus) is this? high level language->assembly language-> byte code(will taken care of virtual machine, convert machine code) -> machine code i've read - so- bytecode vs assembly language code , need understand better bytecode nothing more instruction set vm. implementation of may or may not involve jit machine code. often, not. official lua implementation, example, interprets bytecode rather converting machine code. .net , java implementations compile "hot paths" machine code more efficient execution. ultimately, vm implementation detail , has nothing bytecode itself, instructions vm. object code, afaik, machine code.

probably bad title, don't know how precisely describe this. template.body.helpers({ messages: function () { return messages.find({}, { sort: {createdat: -1} }); } }); this code have. on client side, takes {{#each messages}} <span class="text"> {{messagetext}} </span> {{/each}} each message contains "text" , "username". how go about, in "return messages" part, modifying returns? so like template.body.helpers({ messages: function () { messages.find().foreach(function(thismsg){ messagetext = slugify(thismsg.messagetext) }; } }); get messages, modify fields , return them. perhaps in subscriptions instead? please help. you can pass message in helper , can modify message , pass template this. your template code. {{#each messages}} <span class="text"> {{slugifymessage text}} </span> {{/each}} you helper code. ...

i'm reading mono's marshalling guide , purpose of marshalling strings between objective-c++ , unity (for ios games), , i'm confused string marshalling encodings in mono. i understand string encodings marshalling specified charset enum, allows ansi , unicode (=utf-16) (and auto, makes runtime choose between first two). but guide keeps saying mono marshals strings in utf-8. how possible? magic happens if no charset specified? mean can safely pass -[nsstring utf8string] objective-c++ c#, if don't specify charset? , imply incompatibility microsoft's runtime? the ansi charset value meaningless on non-windows operating systems, in case utf-8 used, case ios. this incompatibility ms runtime, bigger incompatibility in case ms runtime doesn't run @ on ios:).

i'm not sure if did not found information or if it's not possible. i've looked several pages. want use generic generic version of nsorderedset in swift. with set can this: swift’s set type bridged foundation’s nsset class. source: apple docs - sets in nsmanagedobject subclass can change nsset set , work. (tested it) @property nsarray<nsdate *> *dates; @property nsset<nsstring *> *words; @property nsdictionary<nsurl *, nsdata *> *cacheddata; var dates: [nsdate] var words: set<string> var cacheddata: [nsurl: nsdata] source: apple docs - lightweight generics but couldn't find reference ordered set in swift. use nsorderedset objective-c won't have generics in swift then. is there possibility define order in set in swift? no, there no ordered set in swift , in honesty, shouldn't using ordered set period. of use. but times, useful. don't have sort data yourself. when have entity list of sub entiti...

i'm using word "warping" because word explain want do, i'm not sure suitable term... what want achieve find operation modify image image. i'll explain myself : have 2 images similar (the same scene, same moment not same point of view), want know how transform image1 image2, transformations have do. so, thinking : if want transform i1 i2 : convert i1 , i2 b&w pictures. apply sobel filter. create patches both images (little image part of big images). 15px*15px patches. find differences between i1.patch(x,y) , i2.patch(x,y) , find transformation transform i1.patch(x,y) i2.patch(x,y). for patches, apply transformation on coloured image. do think it's idea that? know method better? and if think it's idea, have idea point number 4 above? because have idea, think i'm little naive think it'll work: use 2 matrices , find path transform 1 least possible operations or use standard warping algorithm. i'm use opencv3.0 on wind...
