let me describe scenario before question: let counter defined number starting 0. i have 2 tags: let them a1 , a2 i first dynamically added a1 html , used this: jquery("a.adder").click(function(){adder(this, counter)}); then did counter++ then dynamically added a2 html , used again on both tags jquery("a.adder").click(function(){adder(this, counter)}); then did counter++ also, in adder(param1, param2) , alert(counter) okay here's question: after doing that, when clicked on a1 has 2 handlers, alert output 2 (it alerts twice each handler) , a2, alert 2 when clicked. why happening? the reason returns 2 both anonymous functions creating closure on counter variable. means methods don't have current value of counter when bind them, have reference variable. any changes in variable later on reflected in captured variable. you can prevent creating new variable second binding: var counter = 0; function adder(e, counter) { ...

i need make few changes existing xml files, while preserving formatting , comments - except minor changes should untouched. i've tried xml.etree , lxml.etree no success. the xml generated ide, editor lacking in functionality, have make few manual changes. want keep formatting diffs pretty , not polluting history. with multitude of python xml libraries thought i'd ask here if has done similar. how many , kind of changes need make? sounds me may better served using standalone xml editor (just google them, there lots). frankly, i'm kind of surprised ide doesn't have adequate search-and-replace needs. (most of ones i've seen have regex facilities this.) if need write program make xml changes, , don't want mess formatting , comments, best bet may open xml regular text file in python, , use regular expression library ( import re ) search-and-replace.

i'm building simple website generator application in rails 3.0. i'd "publish" action in controller works ordinary "show" action, instead, saves page html file in "public" directory instead of displaying in browser. is, i'd use rails render mechanism create file instead of providing http response. what's best way this? should add caches_page :publish controller? or use render_to_string , file.new ? you can use render_to_string method: http://apidock.com/rails/abstractcontroller/rendering/render_to_string you still need respond controller though. maybe redirect page saved?

i need make query : select * table cola= "aaa" , ( (colb = "bbb" , (colc="ccc" or colc = "ddd")) or (colb="eee" , colc = "fff") ) i tried andexpression() , orexpression() , openexpression() or closeexpression() , can't figure out ! appreciated ! whereexpression , andexpression etc. should work (see this question ), doesn't work me time, neither. as long where clauses relatively simple, add repetition , use logical operator precedence : select * table cola="aaa" , colb="bbb" , colc="ccc" or cola="aaa" , colb="bbb" , colc="ddd" or cola="aaa" , colb="eee" , colc="fff" this result in this: db.select().from<table>() .where(table.colacolumn).isequalto("aaa") .and(table.colbco...

i know method returning list<string> @ moment. in (which occur quite in our application) scenarios, returns list having only one string. so return either string or list<string> . since it's unpredictable it'll return @ run time, @ present it's return type kept object . what alternative approach used avoid method returning object ? edit: have answer question what alternative approach used avoid method returning object ? ; without considering scenario described. list enough here. why return string ? list<string> single string in perfectly defined... use that! ambiguous api silly here. another option might ienumerable<string> , but... meh, return list single string !

could enlighten me on main differences in c# between enumerations, structs , classes? use classes type of code never seen need use others? refering : introduction objects , classes in c# - introduction introduction objects , classes in c# - world's classes , objects in object-oriented programming programmers write independent parts of program called classes. each class represents part of program functionality , these classes can assembled form program. in our world have classes , objects classes. in our world considered object. example, people objects, animals objects too, minerals objects; in world object. easy, right? classes? in our world have differentiate between objects living with. must understand there classifications (this how name , concepts of class) of objects. example, i'm object, david object too, maria object. people class (or type). have dog called ricky it's object. friend's d...

sorry confusing title. i have form-- form1 has 1 file input ( multiple attribute set user can select mutiple files). form doesn't submitted. i have form -- form2 has single file input . no mutiple attribute. now via javascript fetch each files fileinput previous form , assign file form2's input field , ajax submit. once ajax submit complete same 2nd file , 3rd file , on. i don't want use flash or java applet. aware ie doesn't support multiple attribute opera can use invalid min max attribute same. my basic question how fetch files form1 input field , assisgn form2's field .. is there solution ? or approach incorrect ? what want achieve on ui side ? file gets uploaded , server processing , returns data. want user can select 10 files 1st file uploaded output received. first : idea wrong. cannot assign value via javascript input type = file . i thought of idea using xmlhttprequest. here code : <form id="new_picture_form" meth...

i've got problem that's baffling me bit. here's bit of background: in process of upgrading asp.net 2.0 web app .net 4 onto 64 bit server. have test app deployed both new , old servers make sure things work expected before go live; both of point same database on server. here's problem: double totalgross; double totalnet = 9999999.00; float taxrate = 15.00f; totalgross = totalnet * (1 + (taxrate / 100)); on old server, .tostring() on totalgross produces: 11499998.85 on new server, .tostring() on totalgross produces: 11499998.6115814 currently @ loss why might be? latter value doesn't represent first number un-rounded? by way - i'm not after ways correct/improve code... after possible reasons why happen! update i created console app , built in x86 , x64 , ran both versions on server , outputted 2 different figures. indeed seem sort of loss of precision between 32bit , 64bit when using double. surprise me 'loss of precision in question 0....
