dear competent people. i'm having problem following code, sub completes correctly not copy correct data correct location. repeating pattern of lines of zeros not correlate iterators in place. i think problem copying values sub-set of range, episode&r. looked @ using union property shown wrong commenter below. currently 9 ranges named "episode"1-9 each row of contains data 1 respondent. columns 5 through 15 of these ranges contain data copied, therefore range copied each respondent is: row i, columns 5 through fifteen. step stuck with. if copy it, data end on sheet2 range has been named each respondent, called respondent&n. rows of response&n represent time slots during episode&r can occur. outside of slots episode&r occurs there can zeroes, isn't necessary. the logical structure appears work fine. have watched local values counters closely in debugging , work supposed to. i looking @ using range.item method select row 'n', c

i have been learning ios development few days now. @ moment, have questions on how rootviewcontroller used. searched web 3 hours yesterday looking answer turned quite few results never answered question. i trying learn program app using code (no storyboards/xib files). trying understand how switch between views without using uinavigationcontroller. in project have main delegate creates window, initializes main view controller (which loads separate view well) , adds rootviewcontroller. my first view has button calls function in controller switch next view. here question arises: switch main rootviewcontroller next view or load next view subview of rootviewcontroller? rootviewcontroller supposed encase views application? (i think how uinavigationcontroller works) i have gotten switching of rootviewcontroller work in app, want make sure there isn't other way suppose manage views. i not switch rootviewcontroller, think should remain stable. add subview, or can presen

i'm beginner in linq , have observed inner join query slower , less efficient than, example, crossing tables in code. furthermore, these data charged in listview lighter. here code: public static ienumerable<alumno> getitems() { return (from gal in me.table<grupoalumno>() join alu in me.table<alumno>() on gal.idalumno equals alu.id select alu); } how possible? thank you. i disagree existing accepted answer! linq not operate on ienumerable<t> - can operate on iqueryable<t> , when linq statement executed in query language such sql. in case, linq similar in performance operating directly in sql, has other advantages compile time type checking , intellisense. i agree @anders whenever facing performance issues measuring happening first step - i'd disagree "linq not way go" - i'd opposite - "linq way go" please make sure measure , understand happen

the existing application working on, action classes interact dao classes directly. would better action classes, invoke service layer classes(businessfacade) in turn invoke dao? is better develop layer between action classes , dao layer? it's better because in way can separate business logic (the logic not related naviagtion matters) possible reuse. if separate you'll able reuse business logic in non web application. the data access layer intended layer objects persisted to, , restored from, abstract storage , actually, specially in case of rdbms persistence, may implemented orms, can see business logic layer orm persist objects. prefer merge business logic orm, in case rather front end framework.

i'm getting documents web , many of them binary files (executables, pdf, etc.). in java, correct type hold binary data until save in database? can use string this? use byte array (byte[]) or inputstream (e.g. bytearrayinputstream). java strings not container generic binary data. the apache library commons-io has nice utility classes dealing bytes , streams. e.g. ioutils.tobytearray(inputstream) bytebuffer introduced part of java nio , available in java 4 (1.4) , later. in specialized scenarios, can have performance benefits on using byte[]. has helpful convenience methods. still use byte[], though, since more known, more common in apis, , performs enough.

i'm not familiar graph theory, i'll try explain problem. have dictionnary this: {67: [68, 332], 68: [67], 265: [266], 266: [265], 332: [67, 333], 333: [332, 334], 334: [333, 335], 335: [334, 336], 336: [335]} the keys of dict nodes, , values edges of graph. how can find connected groups in graph? [there 2 groups - 265->266 , 67->...->366] it looks graph undirected, meaning that, 2 nodes , b, if there edge b there edge b a. find connected components of graph, can use depth-first search . start @ node , follow edges until can't reach more nodes without hitting duplicates. first connected component. start @ node haven't touched yet , repeat. you're done when you've reached nodes in graph.

which style preferable? style a: def foo(): import some_module some_module.something style b: import some_module def foo(): some_module.something assume some_module not used elsewhere in code, inside function. indeed, noted, it's best follow pep 8 recommendation , imports @ top. there exceptions though. key understanding them lies in embedded question in second paragraph: "at stage import ... happen?" import executable statement. when import module, executable statements in module run. "def" executable statement; execution causes defined name associated (already-compiled) code. if have: def f(): import return none in module import, (compiled) import , return statements associated name "f" @ point. when run f(), import statement there runs. if defer importing "very big" or "heavy", , never run function (in case f), import never happens. saves time (and space well). of c

i have been trying hang of tdd , unit testing (in python, using nose) , there few basic concepts i'm stuck on. i've read lot on subject nothing seems address issues - because they're basic they're assumed understood. the idea of tdd unit tests written before code test. unit test should test small portions of code (e.g. functions) which, purposes of test, self-contained , isolated. however, seems me highly dependent on implementation. during implementation, or during later bugfix may become necessary abstract of code new function. should go through tests , mock out function keep them isolated? surely in doing there danger of introducing new bugs tests, , tests no longer test same situation? from limited experience in writing unit tests, appears isolating function results in test longer , more complicated code testing. if test fails tells there either bug in code or in test, not obvious which. not isolating may mean shorter , easier read test, not unit tes

by using asihttprequest , asidownloadcache able continue previous downloaded session.now don't want use asidownloadcache.so,is there alternatives achieve it. in advance. if server supports it, can specify content-range field in header of http request , ask small portion of file @ once. when portions, can assemble file together. you can set http headers nsmutableurlrequest setvalue:@"0-1023/*" forhttpheaderfield:@"content-range"]; , example downloads 1024 byte of file. see content-range in http://www.w3.org/protocols/rfc2616/rfc2616-sec14.html this way can download file in parts , next time when want resume download can continue next part don't have yet.

if have getter method has 1 statement this public class numberclass{ int number; public int getnumber() { return number; } ... } and multiple threads access method, have synchronize method or not necessary since has 1 statement?? it has nothing 1 or more statements. depends on whether or not value has been updated in thread , if want of threads see consistent value. if number field updated in thread1, thread2 may either original value or new value depending on how update sychronized . if set not synchronized or not value subject race conditions. you can use volatile keyword or atomicinteger share value between multiple threads reliably.

are there object representation of these comparison operators (<, <=, ==, >=, >, !=) in java ? e.g. use case: void filterhotel( object operator, float rating ) { string query = "select hotel.name hotel hotel.rating " + operator.tostring() + rating; // execute query } no . easy write, consider using enum custom method: public enum operator { equal("=="), not_equal("<>"), greater_than(">"), greater_than_or_equal(">="), less_than("<"), less_than_or_equal("<="); private final string representation; private operator(string representation) { this.representation = representation; } public string getrepresentation() { return representation; } } pass e.g. operator.less_than , extract actual operator using operator.getrepresentation() . also make sure user cannot put arbitrary string in place of o

i have 3 divs: <div id="main"> <div id="one"></div> <div id="two"></div> </div> div "one" contains content height 300px example. div "two" contains more or less content height 400px example. both content changing, it's not static cannot calculate heights manually. style of div "two" contain "overflow-y: scroll;" how create div "two" same height div "one" can smaller or bigger? here quick sketch: using javascript, like: document.getelementbyid("two").style.height = document.getelementbyid("one").clientheight;
