i'm new boost (and stackoverflow) , want use multiarray of vectors. have done way: typedef boost::multi_array<std::vector<vector3_t>, 2> array_type; array_type* mimage; int mresolution = 1000; mimage = new array_type (boost::extents[mresolution][mresolution]); //works mimage[0][0].origin()->push_back(vector3_t()); //error: abort() mimage[1][1].origin()->push_back(vector3_t()); //error: abort() mimage[500][440].origin()->push_back(vector3_t()); on internet can find examples of multiarray use int,doule , on. possible use std::vector in mutliarray ? know use 3d multiarray, prefer vectors elemet. boost.multiarray supports std::vector elements. in general, boost.multiarray perform concept checking @ compile-time. thus, if code compiles complete type, should supported. with mimage[0][0].origin() : mimage[0][0] returns reference std::vector<vector3_t> . origin() not member function on std::vector<vector3_t> , resulting in erro

i converted pojo data json string way, gson gson = new gsonbuilder().disablehtmlescaping().create(); string json=gson.tojson(user); i got json string not format need, got json = {"userid":300,"username":"asd","password":"s","enabled":1} so, want convert json string key-value pair below , {"userid":300,"username":"asd","password":"s","enabled":1} into json string value (without key) below [300,"asd","s",1] you whack properties of user list<object> , json that. this mean gson made json array out of list , want. as doesn't seem make sense use case have bit of hardcoding - don't think gson can you: final list<object> props = new linkedlist<>(); props.add(user.getid()); props.add(user.getusername()); //etc final string json=gson.tojson(props);

i wanted draggable table rows, found tablednd jquery plugin , works fine $(function() { $("table").tablednd(); }); as can see there: http://jsfiddle.net/drbfs/1/ . but wanted make 1 column draggable. mean, whole row (tr) moved now, can move row dragging left column (td.drag), when trying drag right column should no effect. have got idea how can done? it appears older plugin, might have been possible @ 1 point, according document: http://isocra.com/2008/02/table-drag-and-drop-jquery-plugin/ however, after looking through source now, no longer possible. instead, perhaps consider using jquery ui sortable. if wrap rows in tbody, code want: jquery(function () { jquery('table tbody').sortable({ handle:'.drag' }); });

i wish add compression our spring based web-service (serving both xml , json), see there number of different gzip compression filters, not sure which accepted common i.e. there jboss or spring offering? additionally have read compressing content below 1000-860 bytes pointless compression time greater time saved , if below 150 bytes object grows . do these filters support minimum object size out of box? this old thread, compression in filter happens before jsp rendered. possibly enable through apache, doing filter using servlets/filters or spring mvc isn't going you: http://forum.springsource.org/showthread.php?45604-using-gzip-for-compression-how i notice reading question using xml , json responses. possibly still gain benefit @ spring mvc/controller level if looking for, still pursue gzip capabilities in apache. http://betterexplained.com/articles/how-to-optimize-your-site-with-gzip-compression/

i creating 1st ecommerce website. after searching lot confused whether use session , db or cookie . some says session best because not every user purchases have in cart, db heavy. some says db should used cart data persist in different sessions . what best choice? sites do? note: user must login buy something. edit: that, when user add in cart insert in db temptable have foreign key of userid(user must login buy something). when users checkouts records table deleted , inserted perminent table. if user left pc few hours, have login , data there(session problem solved). if uses pc, have login , data there(cookie problem solved). if removed cookies, data still there(cookie problem solved). is technique? personally wouldn't rely on sessions hold basket. customers can quite spend time on site, wander away - perhaps desk. should happen, , have left browser , session expires, cart... there plenty of other reasons too. maybe started shopping, closed

the pre/post build events in visual studio has bugged me few years, haven't got around research better alternative. thing want achieve pretty same post build events: call piece of code before or after project build. the 2 things pre/post build events bugs me (1) code separated project , compiled command line .exe , (2) every error end cryptical message in error pane. i ideally want write static method inside project gets called before or after project builds , if exception pops up, gets stack traced other exception in debug mode. what existing (simple) approach can use done?

i have asp.net web api web service throws serializationexception in circumstances. problem i'm unable trap , log exception server-side -- place shows in body of http response client. i registered exceptionfilterattribute described in exception handling in asp.net web api , verified works when throw exception within controller. unfortunately serializationexception being thrown during response (after controller) , appears swallowed asp.net. tried hooking application_error() in global.asax.cs didn't show there either. how can catch serializationexception exceptions during web api response? if, instead of returning object, use apicontroller.createresponse() method , return httpresponsemessage can response.content.loadintobufferasync().wait() , force serialization happen whilst still in action , therefore can catch exception.
