i have product page has 3 x drop down lists allow visitor select product attributes - example pair of trousers colour / waist size / leg length. currently have drop downs hooked cascading use of jquery , json - each selection populates next drop down list down hierarchy calling jsonresult action via jquery within page. when selections made, , visitor has decided upon product variant, need update page contents - elements such price / image / stock availability / long description , table of specifications can product variant specific. these page elements need change distributed throughout markup rather being in 1 block complicate matters little. currently page (view) has these elements within main view - best way achieve changing page reflect visitors choice? this webforms app made use of several updatepanels achieve same thing, relative mvc newbie i'm not sure of approach tackle kind of problem? thanks. basically have 3 major options: display prerendered vi

while building project, got below error message. the type 'tracker_ascx' exists in both 'appdata\local\temp\190\temporary asp.net files\root\web_tracker.ascx.7a9a6bd4.fnv2mhdj.dll' , 'appdata\local\temp\190\temporary asp.net files\root\web_tracker.ascx.7a9a6bd4.pxdl7dxj.dll'. the application runs in .net framework 4.0 this happend because may have reference of old dlls if u added new version. clean solution , rebuild it.

why uses polymorphism in java while using collections. what difference between these initializations. private list<order> orderlist = new arraylist<order>(); private arraylist<order> orderlist = new arraylist<order>(); in second form, orderlist can treated arraylist<order> or inheriting arraylist<order> . in first form, orderlist treated list<order> , recommended when use functionality defined list<t> interface. way code more flexible , can refactored (e.g. realize need linkedlist<t> instead, change initialization , of code not need changed). also, helpful code refactoring use interfaces instead of actual types, if possible (e.g. use parameters of type list<t> instead of arraylist<t> ), because allows caller change list type without changing in called function.

i have 2 codes: normal: int* p[5]; (int i=0;i<5;i++){ int s = rand()%25; p[i]=&s; } dynamic: int* p[5]; (int i=0;i<5;i++){ int* s = new int; *s = rand()%25; //edit: typo, didn't want make random pointer p[i]=s; } now if print array p, p[i] first , then: *p[i] after it, get: static dynamic 0x22ff04 7 0x22ff30 7 0x22ff04 7 0x22ff24 14 0x22ff04 7 0x22ffa6 2 0x22ff04 7 0x22ff89 8 0x22ff04 7 0x22ff13 21 now why elements in p pointing @ same location normal declaration while in dynamic declaration there multiple objects created? why this? in first case, entries point s , left dangling moment s goes out of scope. dereferencing p[i] leads undefined behaviour. in second case, each entry points separate heap-allocated object. here, there's no undefined behaviour (but there's memory leak).

my question is, how can cursor size (in kbs) without fetching ? i've examined lot of question such here don't want fetch query result learn how kb it. i want like: var mongoclient = require('mongodb').mongoclient, test = require('assert'); mongoclient.connect('mongodb://localhost:27017/test', function(err, db) { var collection = db.collection('simple_query'); // insert bunch of documents testing collection.insertmany([{a:1}, {a:2}, {a:3}], {w:1}, function(err, result) { test.equal(null, err); collection.find(/**some query*/).size(function(err, size) { test.equal(null, err); test.equal(32111351, size); // in bytes or kilobytes whatever db.close(); }); }); }); something this? var avgsize = db.collectionname.stats().avgobjsize; // ... collection.count(/* query */, function(err, count) { var approximatesize = count*avgsize; // work simple database models } i know not perfect,

i understand basic inheritance , understand basics of generics. but not understand class definition: public class exportcontroller : abstractfeedcontroller<iexportfeed> the exportcontroller inherits abstractfeedcontroller ... but, <iexportfeed> do/mean? generics? yes, generic definition. in short, abstractfeedcontroller defines generic implementation can applied various types including iexportfeed in case. look @ definition of class abstractfeedcontroller , see class abstractfeedcontroller<t>{ ... in class see type t used multiple times. whenever see t , can swap in mind type think can apply. in class definition, might see where t : ... . condition on type t , limiting kind of types class can use. read this msdn article in-depth explanation.

i came across stackoverflow question: when use struct? in it, had answer said bit profound: in addition, realize when struct implements interface - enumerator - , cast implemented type, struct becomes reference type , moved heap. internal dictionary class, enumerator still value type. however, method calls getenumerator(), reference-type ienumerator returned. exactly mean? if had like struct foo : ifoo { public int foobar; } class bar { public ifoo biz{get; set;} //assume foo } ... var b=new bar(); var f=b.biz; f.foobar=123; //what happen here b.biz.foobar=567; //would overwrite above, or have no effect? b.biz=new foo(); //and here!? what detailed semantics of value-type structure being treated reference-type? every declaration of structure type declares 2 types within runtime: value type, , heap object type. point of view of external code, heap object type behave class fields , methods of corresponding value type. point of view of inter
