php - Paypal IPN sandbox test -
in ipn script using variable called num_of_items. utilize loop loop thru each item create sure cost , cost paid correct.
the problem ipn works great when straight utilize method. however, when utilize post method , test via paypal's sandbox ipn simulator won't pass value script. so, script doesn't set database.
i know how can test ipn script via ipn simulator pass in variable?

ruby on rails - session[:previous_url] with endless scrolling -
when user logs in or signs in application redirected page on.
this code in application_controller.rb:
def after_sign_in_path_for(resource) session[:previous_url] || root_path end the problem i'm using ajax , will_paginate implement endless scrolling. when user has scrolled past first page , login redirected url looks this:
www.example.com/path_=1412539956365&page=6 showing posts on page 6. how redirect to:
www.example.com/path
you utilize regex strip out query strings. here illustration using rails console:
?> session[:previous_url] => www.example.com/path_=1412539956365&page=6 ?> session[:previous_url][/[^\?_]+/] => "www.example.com/path" you can alter function to:
def after_sign_in_path_for(resource) session[:previous_url][/[^\?_]+/] || root_path end ruby-on-rails
java - Correct way to create a JFrame -
this question has reply here:
extends jframe vs. creating within the program 6 answersi reading 2 ways of creating jframe , don't undersand improve or differences:
import java.awt.*; import javax.swing.*; public class myframepanel { public static void main(string[] args) { jframe myframe = new jframe("myframepanel"); .... and 1 find in books:
import java.awt.*; import javax.swing.*; public class buttonframe **extends jframe**{ public buttonframe() { super("button frame"); setdefaultcloseoperation(jframe.exit_on_close); ... setvisible(true); } public static void main(string[] args) { buttonframe bf = new buttonframe(); } } i going utilize first 1 -i found in stackoverflow- wonder why of books reading java using "extends jframe" one.
thank much , sorry bothering if question stupid.
the first 1 choice. think composition on inheritance.
to favor composition on inheritance design principle gives design higher flexibility, giving business-domain classes , more stable business domain in long term.
if won't utilize myframepanel within jframe, instead in applet, it's easier switch , improve maintain in long term.

jsf - Edit commandLink goes to Edit page but does not populate values into input fields -
my edit page not display bean values when it's called datalist populated jdbc search works fine if list not jdbc search.
the delete link works fine edit link returns edit page no populated values in fields.

if utilize @viewscoped bean, jsf create new instance of when navigate list page edit page. have 3 alternatives can think of:
@sessionscoped. open edit page via ajax , popup panel. use @viewscoped, add together user id url view parameter (ie. edituser.xhtml?id=123), , load user info db in edit page instead of list page, on page load. in scenario, it's best have different managed beans list , edit pages. jsf jsf-2
javascript - Passing two different arguments to function -
i have written jquery functions, , realized needed reuse code situation. refactored code take selector arguement, can utilize case 1, , case 2. however, when execute functions in document.ready weird results.
$( document ).ready(function() { imagecalc('.com-background > img'); setimagedims('.com-background > img', '#main-content'); imagecalc('.blog-entry-content iframe'); setimagedims('.blog-entry-content iframe', '#content'); }); it should noted, these selectors no show on same page. also, when run 1 instance of imagecalc() , setimagedims() these functions work fine. here functions in question..
function imagecalc(selector) { var obj=$(selector); $imgwidth = obj.width(); $imgheight = obj.height(); $imgaspectratio = $imgheight / $imgwidth; // $(selector).css('margin-left', function( calcmargin ) { homecoming parseint($('.main-content').css('padding')) * -1 + "px"; }); prepare ie obj.css('margin-left', '-10px' ); } function setimagedims(selector, content_area) { var container = $(content_area); $(selector).css('height', function() { homecoming $imgaspectratio * container.width(); }); $(selector).css('width', function() { homecoming container.width() + 20; }); } in summary, code works fine, when have each function called 1 time in document.ready need utilize code 2 scenarios, how can this?
add var in front end of $imgwidth, $imgheight, , $imgaspectratio variables. without var, they're beingness declared @ global scope, , hence accidentally getting shared across both calls function.
update: noticed $imgaspectratio beingness used both functions. perhaps can create homecoming value first function, can passed sec function.
to elaborate... should theoretically work, although i'm not able test since don't have corresponding html:
function imagecalc(selector) { var obj=$(selector); var $imgwidth = obj.width(); var $imgheight = obj.height(); var $imgaspectratio = $imgheight / $imgwidth; // $(selector).css('margin-left', function( calcmargin ) { homecoming parseint($('.main-content').css('padding')) * -1 + "px"; }); prepare ie obj.css('margin-left', '-10px' ); homecoming $imgaspectratio; } function setimagedims(selector, content_area, $imgaspectratio) { var container = $(content_area); $(selector).css('height', function() { homecoming $imgaspectratio * container.width(); }); $(selector).css('width', function() { homecoming container.width() + 20; }); } $( document ).ready(function() { var ratio1 = imagecalc('.com-background > img'); setimagedims('.com-background > img', '#main-content', ratio1); var ratio2 = imagecalc('.blog-entry-content iframe'); setimagedims('.blog-entry-content iframe', '#content', ratio2); }); javascript jquery

java - Why can't this class find this array? -
i have array works in first class (coloredwordsexperiment), while sec class, (buttonhandler), cannot find it.
the unusual thing if i, in buttonhandler class, substitute coloredwords.labels[i] or let's "coloredwords.labels[1]" coloredwords.labels1, while in first class declare jlabel labels1 = new jlabel; works.
that's had since have 12 labels decided utilize array instead. problem class buttonhandler cannot find variable "coloredwords.labels[i]".
this code (i left out unimportant stuff otherwise code quite long):
public class coloredwordsexperiment { buttonhandler buttonhandler; coloredwordsexperiment(){ jlabel[] labels = new jlabel[12]; (i = 0; < 12; i++) { labels[i] = new jlabel("press button"); labels[i].setpreferredsize(new dimension(90,40)); labels[i].setopaque(true); labels[i].setbackground(color.white); labels[i].sethorizontalalignment(swingconstants.center); labelcontainer.add(labels[i]); } button1 = new jbutton("matching"); buttonhandler = new buttonhandler(this); button1.addactionlistener(buttonhandler); } public static void main(string[] arg) { new coloredwordsexperiment(); } } -
class buttonhandler implements actionlistener { coloredwordsexperiment coloredwords; public buttonhandler(coloredwordsexperiment coloredwords) { this.coloredwords = coloredwords; } @override public void actionperformed(actionevent e){ if (e.getactioncommand().equals("matching")) { (i = 0; < 12; i++) { coloredwords.labels[i].settext("text changed"); } } }
jlabel[] labels variable declared within constructor of coloredwordsexperiment class. move field in class , initialize in class constructor:
public class coloredwordsexperiment { buttonhandler buttonhandler; //it should declared here jlabel[] labels; coloredwordsexperiment() { //this variable within class constructor //jlabel[] labels = new jlabel[12]; //this line initializes labels field labels = new jlabel[12]; // rest of code... } } also, should declare getter method obtain 1 of jlabels within labels variable instead of using direct access variable. create code cleaner.

sql - Oracle - select records in which a subset does not repeat -
i have oracle info set next columns f1, f2, f3, f4 follows:
a, b, c, d a, b, c, e a, f, c, d a, g, c, d i filter out duplicate fields in column f1 , f2 only. illustration above, see line 1 , 2 have identical values (a,b) in field (f1,f2), need either
a, b, c, d or a, b, c, e but not both. final result expect be:
a, b, c, d a, f, c, d a, g, c, d or
a, b, c, e a, f, c, d a, g, c, d how issue oracle statement accomplish goal? have tried:
select * t (rowid,f1,f2) in (select distinct rowid, f1,f2 t) but statement not help , still print out. please help.
below quick , dirty script create testing info set:
create table "t" ( "f1" varchar2(20 byte), "f2" varchar2(20 byte), "f3" varchar2(20 byte), "f4" varchar2(20 byte) ) insert t (f1,f2,f3,f4) values ('a','b','c','d'); insert t (f1,f2,f3,f4) values ('a','b','c','e'); insert t (f1,f2,f3,f4) values ('a','f','c','d'); insert t (f1,f2,f3,f4) values ('a','g','c','h');
is corresponding needs:
select t.* t bring together (select f1, f2, min(rowid) rid t grouping by(f1,f2)) o on t.rowid = o.rid see http://sqlfiddle.com/#!4/dcf9c/4
the inner query remove duplicated on f1,f2 (deterministically keeping minimum rowid in case of duplicates). outer select simple bring together on rowid extract entire row.
if t view, cannot utilize rowid. have rely on instead:
select f1, f2, f3, min(f4) f4 t natural bring together (select f1, f2, min(f3) f3 t grouping by(f1,f2)) o grouping by(f1,f2,f3); see http://sqlfiddle.com/#!4/dcf9c/8
the key thought here create 3-uple distinct f1,f2 , corresponding minimum f3 (inner query). extending 3-uple adding minimum f4 (outer query). can generalized n-uple nesting more queries.

for loop - PHP Find right value for x when x + 20% = 276 -
i need able solve x value x + 20% = y script. y value known in script, x needs solved.
i've tried loop.
the echo $i should output 230, @ moment script doesn't homecoming (blank white screen)
$amount = 276; for($i = 1; $i<300; $i++) { if($i+20% == $amount) { echo $i; } }
basic maths: calculate 120% of value $i:
if (($i/100)*120 == $amount) or improve still, calculate value $i if know value 120%:
$i = ($amount/120)*100; which can simplified to:
$i = ($amount/12)*10; //same goes first snippet: if (($i/10)*12 == $amount) php for-loop

ios - ReactiveCocoa: how to keep signal until the server is connected? -
i have 2 signals (racsignal):
synchronizetoserversignal: signal containing info sent server. serverconnectionsignal: signal containing boolean value indicate connection state. the synchronizetoserversignal triggered when content changed, , signal controlled serverconnectionsignal:
serverconnectionsignal yes, synchronizetoserversignal maintain sending next value (data). if latest value of serverconnectionsignal no, synchronizetoserversignal maintain holding latest value , discarding old values. 1 time serverconnectionsignal sends yes, serverconnectionsignal maintain sending next value again. how utilize reactivecocoa accomplish this?
replaylast give signal holds onto latest value sent , discards old values. if:then:else: allows switch between 2 signals based on value of 3rd boolean signal.
but switch between? since want ignore values, can utilize [racsignal empty] -- switching between signal useful value , signal no values:
[racsignal if:serverconnectionsignal then:[synchronizetoserversignal replaylast] else:[racsignal empty]] subscribenext:^(id x) { // sync here }]; the intent of code made lot more clear helper method in category, though:
@implementation racsignal (helpers) - (racsignal *)guard:(racsignal *)boolsignal { homecoming [racsignal if:boolsignal then:self else:[racsignal empty]]; } @end then can write:
[[synchronizetoserversignal replaylast] guard:serverconnectionsignal] much more clear!

PHP date timestamp timezone not converted properly -
so have code:
$timestamp = 1414708099; echo $timestamp; $date = date_make_date($timestamp, 'utc', 'datestamp'); date_timezone_set($date, timezone_open('america/new_york')); $timestamp = $date->format('u'); echo '<br>'; echo $timestamp; which supposed convert timezone of initial timestamp utc new york.
but ends printing
1414708099<br>1414708099 hence timezone didnt change...
what did wrong?
btw uses drupal 6 date_api.module: http://drupalcontrib.org/api/drupal/contributions!date!date_api.module/function/date_make_date/6
as per comments
a timestamp always utc. can't apply time zone timestamp - consider timezone 0. whatever do, stays 0. asked date formatted u - manual states this:
u: seconds since unix epoch (january 1 1970 00:00:00 gmt).
you can't seconds unix epoch new york. number same location in world. now, had formatted date using, say, $date->format('y-m-d h:i:s') correctly formatted time timezone offset new york.
long story short - there no problem whatsoever here. works intended.

osx - NSTableview View Based Scrolling Performance -
i new os x cocoa programming have decided give go new swift language.
i have nstableview 1500 rows (will more) , 7 columns. there 1 checkbox column , rest text fields, 1 date formate , 1 currency formatter. first set cell based. scrolling buttery smooth (i did test adding 1 1000000 rows, still smooth). under mavericks.
i upgraded yosemite, scrolling performance degraded. enabling core animation layer checkbox on table view improved still worse in mavericks.
during reading trying improve scroll performance in yosemite came across "view-based" nstableviews. documentation said cell based table views should not used , supported legacy projects.
i hence converted table view based table view. sample simple concept, nil complicated. scrolling performance absolutely terrible. if scroll slow smooth plenty start scroll faster hasn't buffered plenty , starts stuttering , jerking. when nstableview populated, focusing , defocusing window takes sec or more (i tried in mavericks 1 time again , not present, scrolling little better, still near cell based).
are view based nstableviews bad scrolling performance? if why apple recommend using them on cell based nstableviews.
also applications safari , reeder2 have buttery smooth scrolling in yosemite. how accomplish this?
am missing or performance of os x going hell each new thing? i.e
mavericks > yosemite
cell-based > view-based
old > new
any help much appreciated. thanks!
according apple, osx never enable quartzcore default (as ios, instead, do). so, need to:
link against quartzcore.framework project under build settings pane. enable coreanimation layer (under view effects inspector on ib) main window (if possible, otherwise sure enable on container view give poor performances).quoting apple docs:
in ios apps, core animation enabled , every view backed layer. in os x, apps must explicitly enable core animation back upwards doing following:
link against quartzcore framework. (ios apps must link against framework if utilize core animation interfaces explicitly.) enable layer back upwards 1 or more of nsview objects doing 1 of following:
in nib files, utilize view effects inspector enable layer back upwards views. inspector displays checkboxes selected view , subviews. recommended enable layer back upwards in content view of window whenever possible. views create programmatically, phone call view’s setwantslayer: method , pass value of yes indicate view should utilize layers. enabling layer back upwards in 1 of preceding ways creates layer-backed view. layer-backed view, scheme takes responsibility creating underlying layer object , keeping layer updated. in os x, possible create layer-hosting view, whereby app creates , manages underlying layer object. (you cannot create layer-hosting views in ios.) more info on how create layer-hosting view, see “layer hosting lets alter layer object in os x.”

echo "row count:"; echo $recycle_sql->rowcount(); and result:
row count:1row count:0row count:0row count:0row count:0row count:0row count:0row count:0row count:0row count:0row count:0row count:0row count:0row count:0row count:0row count:0row count:0row count:0row count:0 as can see, it's first time it's beingness run, there valid row.
what doing wrong?
the explanation right in documentation of rowcount():
if lastly sql statement executed associated pdostatement select statement, databases may homecoming number of rows returned statement. however, behaviour not guaranteed databases , should not relied on portable applications.
in other words, rowcount() not provide info whether code works.
to check if query successful, check homecoming value of execute() or fetch(), both homecoming false on failure. in latter case, create sure compare using === match type. in addition, functions throw exceptions additional information, if query fails. check the examples fetch() on how handle these exceptions.
apart that, not using result in $recycle @ all.

does has thought can problem?
those 2 .jar files depend other .jar files.
look @ project pages this log4j find out .jar files need add together application too.
update:
those .jar files remain in conflict existing java apis used domino server. that's why error without using them in xpage used domino server executing xpage.

var obja = {}; var objb = new object; var objc = {}; objc.tostring = function () { homecoming "objc" }; alert(obja); // [object object] alert(objb); // [object object] alert(objc); // objc if want inspect object, should either console.log it, json.stringify() it, or enumerate on it's properties , inspect them individually using for in.

javascript - What's the good practice to wrap some useful js libraries to angular modules? -
there useful libraries want utilize in angularjs, e.g. jquery, underscore, underscore.string.
it might not thought utilize them straight in angular code(say, controllers, directives), because it's hard mock , test. want wrap them angular modules:
angularunderscore.js
define(['angular', 'underscore'], function(ng, _) { homecoming ng.module('3rd-libraries') .service('underscoreservice', function() { homecoming _; }); }); my questions are:
is utilize.service() define service? or mill or constant better? is utilize underscoreservice, or underscore plenty , better?
i believe question of scope. although disagree, think loading _underscore dependency of every tests suite fine. reason rule of thumb saying "static" operation - - generic algorithm used not application logic or info sensitive, should tested separately (or not @ in case of _underscope frameworks). this makes tests simpler write, more readable , maintainable , putting rare cases aside, these tests fail anyway if _underscore have new bug on sorting array. moreover, can't see benefitting (other mocking, addressed before) di of these algorithm.
however, if algorithm more complex , involves info logic dependency, introduce mill (or service, both singletons) encapsulating logic , making testable itself. far service vs mill (vs provider), there tons of answers out there, liked: this

int j = 0; for(j=0; j<n; j++){ unsigned int ii = (morton_codes[j]>>sft) & 0x07; binsizes[ii]++; } parallel substituting following
int rc,j; pthread_t *thread = (pthread_t *)malloc(nthreads*sizeof(pthread_t)); belong *belongs = (belong *)malloc(nthreads*sizeof(belong)); pthread_mutex_init(&bin_mtx, null); (j = 0; j < nthreads; j++){ belongs[j].n = nthreads; belongs[j].n = n; belongs[j].tid = j; belongs[j].sft = sft; belongs[j].binsizes = binsizes; belongs[j].mcodes = morton_codes; rc = pthread_create(&thread[j], null, belong_wrapper, (void *)&belongs[j]); } (j = 0; j < nthreads; j++){ rc = pthread_join(thread[j], null); } and defining these outside recursive function
typedef struct{ int n, n, tid, sft; int *binsizes; unsigned long int *mcodes; }belong; pthread_mutex_t bin_mtx; void * belong_wrapper(void *arg){ int n, n, tid, sft, j; int *binsizes; unsigned int ii; unsigned long int *mcodes; n = ((belong *)arg)->n; n = ((belong *)arg)->n; tid = ((belong *)arg)->tid; sft = ((belong *)arg)->sft; binsizes = ((belong *)arg)->binsizes; mcodes = ((belong *)arg)->mcodes; (j = tid; j<n; j+=n){ ii = (mcodes[j] >> sft) & 0x07; pthread_mutex_lock(&bin_mtx); binsizes[ii]++; pthread_mutex_unlock(&bin_mtx); } } however takes lot more time serial 1 execute... why happening? should change?
since you're using single mutex guard updates binsizes array, you're still doing updates array sequentially: 1 thread can phone call binsizes[ii]++ @ given time. you're still executing function in sequence incurring overhead of creating , destroying threads.
there several options can think of (there more):
do @chris suggests , create each thread update 1 portion ofbinsizes. might not viable depending on properties of calculation you're using compute ii. create multiple mutexes representing different partitions of binsizes. example, if binsizes has 10 elements, create 1 mutex elements 0-4, , elements 5-9, utilize them in thread so:
if (ii < 5) { mtx_index = 0; } else { mtx_index = 1; } pthread_mutex_lock(&bin_mtx[mtx_index]); binsizes[ii]++; pthread_mutex_unlock(&bin_mtx[mtx_index]); you generalize thought size of binsizes , range: potentially have different mutex each array element. of course of study you're opening overhead of creating each of these mutexes, , possibility of deadlock if tries lock several of them @ 1 time etc...
finally, abandon thought of parallelizing block altogether: other users have mentioned using threads way subject level of diminishing returns. unless binsizes array large, might not see huge benefit parallelization if "do right".

c# - Adding a bool for each property -
i'm building c# class works 2 different info sources. load info source , take configuration set function. want several tasks on properties within object.
for example.
public string streetaddress { { homecoming _streetaddress; } set { if (value.length <= 64) _streetaddress = value; else _streetaddress = value.substring(0, 1024).trim(); } } public string city { { homecoming _city; } set { if (value.length <= 128) _city = value; else _city = value.substring(0, 128).trim(); } } public string state { { homecoming _state; } set { if (value.length <= 128) _state = value; else _state = value.substring(0, 128).trim(); } } so holds info 1 side. hoping able store , set alter flag on each property. if take state example. if person moved texas illinois want set bool within property note alter able loop on changes before saving object db. don't see way assign state variable within property. best way write object on top of command or there more creative way store multiple strings within 1 property?
if you'd oop way of doing thing, can:
define interface , class holding property, such as:
interface ipropertyslot { bool isdirty { get; } void resetisdirty(); object untypedvalue { get; } } class propertyslot<t>:ipropertyslot { public t value { get; private set; } public bool setvalue(t value) { if (!equals(_value, value)) { value = value; isdirty = true; homecoming true; } homecoming false; } public bool isdirty { get; private set; } public void resetisdirty() { isdirty = false; } public object untypedvalue { { homecoming value; } } } store properties within class in dictionary string (for name of property) ipropertyslot , get/set them through pair of methods:
void setproperty<t>(string name, t value) { ipropertyslot property; if (!_properties.trygetvalue(name, out property)) { property = new propertyslot<t>(); _properties[name] = property; } ((propertyslot<t>)property) .setvalue(value); } t getproperty<t>(string name) { ipropertyslot property; if (!_properties.trygetvalue(name, out property)) { property = new propertyslot<t>(); _properties[name] = property; } homecoming ((propertyslot<t>)property).value; } finding changed properties later matter of going on _properties.values , finding of them isdirty.
this approach gives way add together more functionality properties in oo manner (such raising propertychanged/propertychanging events, mapping db fields, etc.).

playframework - Keeping a Play framework app running in a Docker container without a pseudo-TTY -
i have development setup need multiple containers running different services, , i'm trying utilize fig accomplish this. else works fine, 1 of these services play framework app, , not want remain running unless gets pseudo-tty. fine , good, since want coordinate these multiple containers, want fig up, , command not seem allocate pseudo-tty's, process dies after startup, , containers along it.
i've created a repository showcase of problem can clone , run, instructions in readme. if can shed lite on how create e.g. middleman script maintain app running, or other solution fig up linked container setup, that'd brilliant.
alternatively, if using other methods of coordinating multiple containers this, maybe nice shell script runner manages things, welcome insight.
edit: changed accepted reply because new 1 solves problem. workaround reply still has valuable info, though.
fig has been replaced docker compose, , in docker-compose.yml file can add together stdin_open: true setting, should prepare issue:
web: image: brikis98/ping-play ports: - "9000:9000" stdin_open: true in illustration above, brikis98/ping-play image play app executes activator run default. if run docker-compose up on yaml file above, play app boots , keeps running instead of exiting immediately.

php - Optimistic lock in Doctrine2 doesn't work for many to many relation -
i have entity user has many many relation roles. i've tried implement optimistic lock, works fine, when changed roles, doesn't alter version (user entity version), proper behaviour?
class user { /** * user's roles. * * @orm\manytomany(targetentity="role") */ private $roles; ...
doctrine 2's locking mechanisms don't take associations account. protect against changes entities themselves. imho expected, because has no way know associations include , ignore. isn't you'd want happen blindly on associations.
theoretically doctrine 2 accomplish adding alternative association mappings, @ moment isn't supported.
so have 2 options:
try implement such feature, , submit pr :) implement own optimistic locking mechanism take specific association account. php concurrency doctrine2 optimistic-locking optimistic-concurrency

How to pass a value from JavaScript in php? -
translate translator google. did not swear if not clear. russia.
the question arose. how pass value of alert in javascript in variable $ value in php, , write in case file. , question: how hide alert? or utilize instead visually not visible, value passed?
//a lot of code { console.log(data); alert(data['value']); } }); so. there php script writes logs (current page , previous one) file. according principle here:
//a lot of code $home = $_server['http_host'] . $_server['request_uri']; $referer = $_server['http_referer']; $value = how value of java script convey here?; $lines = file($file); while(count($lines) > $sum) array_shift($lines); $lines[] = $home."|".$referer."|".$value."|\r\n"; file_put_contents($file, $lines); it necessary value of js transferred php-script , write file. how it? prompt please. novice in of this.
php scripts run before javascript, means can pass php variables javascript, not other way around. however, can create ajax post request javascript php script, , grab post info in php through global $_post variable.
assuming utilize jquery, javascript like:
// assign info object: var info = { value: "test" }; // send php script via ajax post request: $.ajax({ type: "post", url: "http://your-site-url/script.php", data: info }); and php script like:
// if value received, assign it: if(isset($_post['value'])) $value = $_post['value']; else // else; javascript php jquery json
python - List of ints to string -
i have list of ints:
(83, 105, 101, 109, 101, 110, 115) which believe codes siemens.
how can convert list string in pythonic way?
i know can individual chars chr(x) , concatenate them doesn't seem best way.
using bytes (or str) , bytearray:
>>> bytes(bytearray((83, 105, 101, 109, 101, 110, 115))) 'siemens' in python 3.x:
>>> bytes((83, 105, 101, 109, 101, 110, 115)).decode() 'siemens' python string char int

there's bit of redundancy in current code. starting if-checks, here's how approach this:
var sourcedirectory = new directoryinfo(sourcefolder); // remember this, reused if (sourcedirectory.exists) { // files in directory, if none found, empty array foreach (var file in sourcedirectory.getfiles(pattern)) { file.moveto(path.combine(destinationfolder, file.name)); } // re-check directory remaining files if (sourcedirectory.getfiles(pattern).length == 0) //before deleting create sure temp folder empty. sourcedirectory.delete(); // delete temp folder after moving contents. } as little performance improvement, replace sourcedirectory.getfiles() sourcedirectory.enumeratefiles() in for-loop. allow start moving them method finds them, not after have been found.

for ex--- direction votes party east 5000 bjp east 8000 aap there 1 max value in east direction display count 1.. plz tell me....
<table class="bordered"> <tr> <?php $sqlst = "select distinct state voter_count"; $resultst = mysql_query($sqlst); while($rowst = mysql_fetch_array($resultst,mysql_assoc)) { ?> <td> <table class="bordered"> <thead> <tr> <th colspan="3"><?php echo $rowst['state']; ?></th> </tr> <?php $state = $rowst["state"]; $sqlco = "select distinct district,direction voter_count state = '$state'"; $resultco = mysql_query($sqlco); while($rowco = mysql_fetch_array($resultco,mysql_assoc)) { ?> <tr> <?php $district = $rowco['district']; $direction = $rowco['direction']; $sqlvotes = "select max(votes) vote,direction voter_count state = '$state' , district = '$district' , direction = '$constituency'"; $resultvotes = mysql_query($sqlvotes); while($rowvotes = mysql_fetch_array($resultvotes,mysql_assoc)) { ?> <th><?php echo $rowvotes['vote']; ?></th> <th><?php echo $rowvotes['direction']; ?></th> </tr> <?php } } ?> </thead> </table> </td> <?php } ?> </tr> </table>
not 100% sure final table needs like, start (you don't need first query, can want 1 query):
select max(votes) vote,direction, state, district voter_count grouping direction, state, district as 1 of comments mentioned refer link how utilize grouping by: http://www.w3schools.com/sql/sql_groupby.asp
