i trying pass php variable inside javascript bt not working. <a href="javascript:wait1();getpass('<?php echo $current?>');">comment</a> is possible or may incorrect somewhere... thanks response in advance! :) you're dynamically generating javascript. save headaches if when need you, keep simple. transfer data php javascript in simplest way possible @ top of page: <script type="text/javascript" > var $current = '<%? echo $current; %>'; </script> as others have pointed out, want encode , quote php variable, using json_encode (in case won't need quotes), or simpler escape function if know possible values. now, inline code can simpler: <a href="javascript:wait1();getpass($current);">comment</a> a final recommendation pull out own function, , use "onclick" attribute.

while looking best way search array of objects in javascript (there doesn't seem iterate + compare function that) came across post seems elegant way of doing this. however have questions: javascript doesn't have associative arrays. these seems one. gives? this seems elegant solution how stack against competition? "pass array , comparison function" - means several specific comparison functions various searches. "optimised findbyx functions" - means optimised searches each type needed. " scalalala method" - suspect slowest elegant. also how go taking reponse ajax , creating array similar structure this? tutorials hand-pick , roll examples demonstrate associativity of arrays not how used practically. is there pitfalls using method? decent links ( beyond this ) appreciated. thanks. update: having trouble with. if have data coming server similar this: $.getjson("map.php?jsoncallback=?", function(data) { (var ...

so, total newbie git. been reading through guides , think have basics having difficulties accomplishing 1 goal. i have repo created generic markup source code. stuff reuse every breakout. it's called markupdna.git i have different directories in mac sites dir ~/sites/project-n . build upon generic stuff , breakout of site. these tied main git repo forks, cannot fork own repo? i wish this: git clone <url> name git add . # make changes git commit -m 'whatever' git push but don't want push origin. want push fork of markupdna repo whence cloned. seems pushes changes right origin master. idea keep markupdna clean , have lot of forks different projects, each of have own cloned dir on hard drive. any ideas? it lot easier use branches , rather using separate forks. can still have separate checkouts each branch; clone repo multiple times, , use git checkout in each 1 switch appropriate branch (or git checkout -b create branch , check out @ onc...

what best way choose managing text/binary content on filesystem? typically when building web applications lot of multimedia binaries , other various text based content stored on filesystem, jdk 6 java.io still low level. it change java 7 can see here new java.nio.file.* package but until java 7 out , implemented ides etc., don't know use this, except of org.apache.commons.io. tried few samples jackrabbit, i'm not sure if idea purpose mentioned @ beginning. possible manage filesystem binary/text content jackrabbit ? put nodes , properties instead of directories. bring advantages ? it's not clear you're looking for, google's guava libraries have io package, , in particular, files class full of static methods file manipulation. it's not content repository system, may provide enough functionality you're trying do.

are new objets assigned eden space or eden + fromsurvivor space ? can free space in survivor space used allocation new objects? edit : consider scenario: suppose eden space full , survivor space occupancy less, in case if new object created (new object small enough fit survivor space) minor collection occur or space new object allocated fromsurvivor space? i believe eden space used small objects, , large objects allocated directly in old space. if new objects allocated in survivor space, kinda defeat point of having separate spaces. see this pdf more details, including: most objects allocated in eden. (as mentioned, few large objects may allocated directly in old generation.)

this question asked in interview . except collections.sort() other methods . sorting interfaces comparable<t> , comparator<t> standard interfaces used standard java sorting options (all except on primitive arrays, is). in java-speak, class implements comparable has "natural order". (technically, must implement comparable<? super e> e matches itself, have natural order). classes don't have natural order can sorted using external comparator. comparator can used implement sort order runs against natural order (e.g. sort strings in descending alphabetic order). these principles applied both in sortedset<e> , sortedmap<k,v> implementations, sort elements / keys automatically using either natural order or supplied comparator. these same principles can found in static utility methods arrays.sort(arr) , arrays.sort(arr, comparator) arrays collections.sort(list) , collections.sort(list, comparator) lists that can u...

is there way insert/select linq translates sql: insert tablea (...) select ... tableb ... yes @bzlm covered first, if prefer bit more verbose: // dc = datacontext, assumes tablea contains items of type var toinsert = b in tableb ... select new { ... }; tablea.insertallonsubmit(toinsert); dc.submitchanges(); i kind of prefer review/maintenance point of view think bit more obvious what's going on in select. in response observation @jfbeaulac : please note will not generate sql shown - far i'm aware it's not possible generate directly using linq (to sql), you'd have bypass linq , go straight database. functionally should achieve same result in perform select , insert data - round-trip data server client , may not optimal large volumes of data.

in various c++ code see different usage of strings: pwstr, char*, std::string, cstring, etc ... when best time use pwstr compared other string type? a pwstr wchar_t string pointer. unicode (usually ucs2) string each character taking 16 bits. a char* pointer 8 bits per character. ascii, ansi, utf8, or 1 of many hundreds of other encodings. although need worry encodings if need string hold languages other english or special symbols. in general, windows api unicode internally windows programmers use wchar strings. std::string , cstring can both unicode if right symbols #defined , choice between pwstr , std::string , cstring matter of preference or convention of codebase work with.

i storing datetime values in sqlite database (using delphi , disqlite library). nature of db such never need transferred between computers or systems, interoperability not constraint. focus instead on reading speed. datetime field indexed , searching on lot, reading in thousands of datetime values in sequence. since sqlite not have explicit data type datetime values, there several options: use real data type , store delphi's tdatetime values directly: fastest, no conversion string on loading; impossible debug dates using db manager such sqlitespy, since dates not human-readable. cannot use sqlite date functions (?) use simple string format, e.g. yyyymmddhhnnss: conversion required relatively easy on cpu (no need scan separators), data human-readable. still cannot use sqlite date functions. do else. what's recommended thing do? i have read http://www.sqlite.org/lang_datefunc.html there's no mention of data type use, and, not being formally schooled in programm...

our customer advertises products product's attributes vastly different 1 another. there many product "classes" there products. originally, created eav database added , removed attributes each "class" of product. whole thing works well, complexity mind numbing. this database #1. we came set of fields common represent products (pocos), moving "extra" fields xml field "catch all". this database #2. now have customers using old , customers use new. didn't want update old until needed so, have changes time time take longer necessary because of eav structure. questions: any examples out there on how code ef persist pocos eav databases (where have table of field names , table of data)? should scrap database , write "normal" tables older customers, given have changes time time? normal of course referring boyce codd normal form. we handled older database bleeding structure software, mapping pocos in repository. ...

let's article has many tags through taggings. article has_many :taggings has_many :tags, :though :taggings end @article.tags #gives tags article how find tags article not have? thanks the way can think of using rails finders 2 queries , subtract: class article def unused_tags tag.all - self.tags end end alternately, through sql (which more efficient since you'd getting rows want ): query = <<-eos select * tags t not exists ( select 1 taggings article_id = ? , tag_id = t.id ) eos tag.find_by_sql [query, article.id]

how apply function every element in list using linq in c# method reduce() in python? assuming you're talking this reduce function , equivalent in c# , linq enumerable.aggregate . quick example: var list = enumerable.range(5, 3); // [5, 6, 7] console.writeline("aggregation: {0}", list.aggregate((a, b) => (a + b))); // result "aggregation: 18"

everyone! i'm quite new regular expressions, them, lot! call me nitpicky if will, i'd know if should avoid using lookaheads , lookbehinds if have option. for example, 2 commands below same thing, 1 uses lookbehind , other doesn't. the_str = regex.replace(the_str, @"(;|!|\?) \.{3}", "$1..."); the_str = regex.replace(the_str, @"(?<=(;|!|\?)) \.{3}", "..."); which 1 use? more efficient? thanks answers! i tested both locally , method using lookbehind 25% slower. another variation tested using lookahead instead of lookbehind 10% slower: s = regex.replace(s, @"(;|!|\?) (?=\.{3})", "$1"); i don't think there's enough of performance difference advise avoiding lookarounds. if think makes code more readable use them. optimize performance if profiling shows have performance problem , regular expression bottleneck. for information, string tested on "blah; ... foo ...; bar bar ? ....

i denying user ability drop tree during conditions, it's going well, want tell user why i'm denying drop. prefer tooltip, doesn't seem work. can not have tooltip during drag operation? how can force one? flex seems treat tooltips property of ui component, component deciding when , if show it. force doing 1 in javascript saying "show now" "stop showing now" does know doing during drag? thanks ~mike what try show tooltip mx.managers.tooltipmanager . create example vbox implements mx.controls.tooltip , displays message want show user. you can see working example @ flexexamples . another idea show programmatic mouse cursor when drop denied. i've read article on inside ria .

i want ask question because php documentation doesn't mention it how 1 put xml data , binary data together? $imagecontent = @file_get_contents($imagelocation); $xmldata ="<xml></xml>"; $headers = array("mime-version: 1.0"); curl_setopt($ch, curlopt_customrequest, "put"); curl_setopt($ch, curlopt_httpheader, $headers ); curl_setopt($ch, curlopt_postfields,$data); i know if pass $data array, curl automaticly set multipart, how can associate different content types different contentvariables? $xmldata $imagecontent content-type: application/atom+xml content-type: "jpg" i have sample wich done fputs , more inline , uses boundary. don't know if have curl , if how it? can provide samplecode please? thanks, richard i've found answer similar question , can useful you.

i have group of equations , i'd show under transformation, system looks else. i'd group ams align environment inside pair of brackets such align environment vertically centered on line , can like: (that uses matrix environment, alignment centered.) i using lyx. \begin{equation} \left\{ \begin{matrix} x = & y \\ y = & -x-\mu(x^4-1)y \end{matrix} \right\} \rightarrow \left\{ \begin{matrix} w = & -x \\ x = & w-\mu f(x) \end{matrix} \right\} \end{equation} produces closely thing shown above.

i have model called contacts. contacts can have different status "bad, positive, wrong..." these status may need changed on time, across contacts, same options. should model way: contacts.rb belongs_to :status_contact statuscontacts.rb has_many :contacts then manually populate types of status in table? i want use ajax click button corresponding value update value contacts. it looks you're trying ensure values status going restricted set of possible answers of choosing. if that's you're trying do, there's no special need separate table. can use magic of activerecord validations instead here. first, create string database column contact called :status. then can use validation ensure values limited ones want. in rails 3, can this: validate :status, :inclusion => { :in => %w( bad positive wrong ) } (if you're using rails 2, use #validates_inclusion_of instead.) in activerecord, validations check object's values...

i'm writing web service returns different types of errors. each method can return 1 of 3 basic types of errors: general , invalidinput , or non . in addition 3 possible values, each method can have it's own errors (e.g. signin method - invalidpassword) - each method can return 1 error. example signin method able return 1 of following error types: general, invalidinput, non, invalidpassword. @ first thought of using enums, think error types should implement inheritance because there basic 3 types, , each new method's error types inherit that.. can't think how. thought of using static class - have 1 string static field - , inheritance irrelevant again... problem enums web service's client meaningless int (through json) so question is: way of conveying idea there 3 basic possible values, , can add make new type of errors? it best if reconsidered interfaces. it far better use exceptions on error codes not because easy forget checking error code, b...
