Not able to group similar records in XSLT -

Not able to group similar records in XSLT -

i trying grouping similar records based on language. not able grouping in xslt. using xsl key function grouping record in xslt. trying loop , add together each grouping records 1 group.

i have next input xml.

<root> <element name="david" language="german"></element> <element name="sarah" language="german"></element> <element name="isaac" language="english"></element> <element name="abraham" language="german"></element> <element name="jackson" language="english"></element> <element name="deweher" language="english"></element> <element name="jonathan" language="hindi"></element> <element name="mike" language="hindi"></element> </root>

xslt:

<?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/xsl/transform" xmlns:xs="http://www.w3.org/2001/xmlschema" exclude-result-prefixes="xs" version="1.0"> <xsl:key name="lang" match="element" use="@language"></xsl:key> <xsl:template match="/"> <root> <xsl:for-each select="key('lang',//element/@language)"> <group> <xsl:attribute name="name" select=".//@language"></xsl:attribute> <member><xsl:value-of select=".//@name"/></member> </group> </xsl:for-each> </root> </xsl:template> </xsl:stylesheet>

expected output :

<root> <group name="german"> <member>david</member> <member>sarah</member> <member>abraham</member> </group> <group name="english"> <member>isaac</member> <member>jackson</member> <member>deweher</member> </group> <group name="hindi"> <member>jonathan</member> <member>mike</member> </group> </root>

actual output :

<root> <group name="german"> <member>david</member> </group> <group name="german"> <member>sarah</member> </group> <group name="english"> <member>isaac</member> </group> <group name="german"> <member>abraham</member> </group> <group name="english"> <member>jackson</member> </group> <group name="english"> <member>deweher</member> </group> <group name="hindi"> <member>jonathan</member> </group> <group name="hindi"> <member>mike</member> </group> </root>

i getting each records separately. can please allow me know went wrong in xsl. :)

i made changes in stylesheet. should accomplish result expect:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/xsl/transform" version="1.0"> <xsl:output indent="yes"/> <xsl:key name="lang" match="element" use="@language"></xsl:key> <xsl:template match="root"> <xsl:copy> <xsl:for-each select="element[count(. | key('lang', @language)[1]) = 1]"> <group name="{@language}"> <xsl:for-each select="key('lang', @language)"> <member><xsl:value-of select="@name"/></member> </xsl:for-each> </group> </xsl:for-each> </xsl:copy> </xsl:template> </xsl:stylesheet>

the first loop selects each unique language (a node-set of size 3), , creates context inner loop. inner loop iterates through each element , selects ones have same language.

muenchian grouping may seem hard grasp, can apply template shown in this tutorial , not have think much. applied template example.

update: here solution without using for-each loops:

<?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/xsl/transform" version="1.0"> <xsl:output indent="yes"/> <xsl:key name="lang" match="element" use="@language"></xsl:key> <xsl:template match="root"> <xsl:copy> <xsl:apply-templates select="element[generate-id(.) = generate-id(key('lang', @language)[1])]"/> </xsl:copy> </xsl:template> <xsl:template match="element"> <group name="{@language}"> <xsl:apply-templates select="key('lang', @language)" mode="member"/> </group> </xsl:template> <xsl:template match="element" mode="member"> <member><xsl:value-of select="@name"/></member> </xsl:template> </xsl:stylesheet>

sql - Automated Heroku PostgreSQL Updates without Client Request -

i new web development. building simple text based web game. using heroku , postgresql. have sql table users , coin amount(their earnings).

i can receive/transmit info database using requests made players. want accomplish automate coin add-on each users account.

so let's @ origin of each hour, want add together 15 coins each user. how can possible accomplish kind of automation heroku , postgresql ?

i tried searching hour, wasn't able find name of process :(

while schedule (as sonnyhe notes), it's improve not to.

instead, update value when you're updating balance other reason, adding difference between time lastly added coins , current time, extracting hours, , multiplying 15.

if user asks view balance, need display lastly stored value plus hours since * 15.

that way you're not doing lots of unnecessary updates , causing unnecessary load.

Git-Repository inside Git-Repository (no submodule) -

Git-Repository inside Git-Repository (no submodule) -

i want utilize gitrepository within gitrepository. know there submodules read aren't great. right created git repository, added .gitignore , accepted files via whitelist. created directory within , created git init new git repository within root repository. right works without problems...

i seek visualize situation:

root-repository - .git - script.bat - readme.md - .gitignore (which ignores * , whitelists !script.bat !readme.md !.gitignore) - directory - - .git - - .gitignore - - other files...

what want achieve? root-repository should first repository every developer pulls. runs script (which git clones projects, adds environment variables, build dependencies , on..).

is okay or there downsides?

i haven't worked git submodules yet, can't compare 2 solutions. have done similar thing, similar reasons, difference root project not git repository. situation this:

root_directory - git_repo_1 - git_repo_2 - ... (more repos) - project_build_repository.

the project build repository contains scripts cloning entire project , building (the entire project built various subprojects, each of can built or used independantly).

there few downsides doing this, , there additional downside approach have taken not nowadays in variant have done.

the general downside whenever have apply operation all/multiple repositories, have manage manually, or manage script. leads variety of derivative problems -- forget something, have maintain scripts, deviate idiomatic way of doing things git -- depending on how work around root problem.

the disadvantage approach has on mine 1 of ambiguity. naive user might git command (status, force etc) , expect submodules be handled correctly not be. compound issues discussed in previous paragraph.

i don't recommend approach (i evaluating utilize of git submodule , comparing tradeoffs in near future), in approach user following:

create project dir. in project dir, clone project_build_repo. run initial clone script, checks out submodules in right paths.

in case readme etc info goes in project_build_repo.

good luck.

is possible phone call apache solr url jquery autocomplete or shall write restful client json data, pls help me out.

yes, if javascript running in localhost:8983. if not, phone call violate cross-domain policy of browser.

if not, need create simple backend bouncer on same domain website. so, if solr running @ localhost:8983 , website running @ localhost:80, need backend helper javascript.

the js in question quite simple, can utilize $.get or $.getjson. recommend getjson this, see documentation , examples @ http://api.jquery.com/jquery.getjson/.

i have no clue how backend built, c# mvc ajax controller action bouncing this. note wrote without testing, not work straight can utilize guideline.

php - issue with mysqli query when I use the function to run the query -

why error when run query using mysqli within function? works fine outside of function. when running function, error states "$db" variable undefined.

<?php $username = 'username'; $password = 'password'; $db = new mysqli('localhost', 'root', 'root', 'rocketforce_blog'); $result = $db->query("select * users user_name = '$username' , password = '$password'"); $row = $result->num_rows; $cnt = count($row); echo $cnt; //======================================================================================= function user_exists($username, $password) { $result = $db->query("select * users user_name = '$username' , password = '$password'"); $row = $result->num_rows; $cnt = count($row); homecoming $cnt; } echo user_exists($username, $password); ?>

the variable $db not known in scope of function. if want known in function, either have pass $db parameter function. eg

function user_exists($db, $username, $password) { $result = $db->query("select * users user_name = '$username' , password = '$password'"); $row = $result->num_rows; $cnt = count($row); homecoming $cnt; } echo user_exists($db, $username, $password);

or import global $db variable scope of function. that:

function user_exists($username, $password) { global $db; $result = $db->query("select * users user_name = '$username' , password = '$password'"); $row = $result->num_rows; $cnt = count($row); homecoming $cnt; } echo user_exists($username, $password);

c# - List with Associated Detail Box GUI -

i'm working in c# / wpf , i'm trying develop window has next layout:

the thought click each item in datagrid , see associated details of item in command below datagrid. i'm not sure kind of command house expanded details. question around options how accomplish kind of ui, i'm novice @ wpf.

a neat , easy solution have 2 separate views. 1 embedded in other. grid listed items main view. details panel sec view embedded in first one.

to communicate item selected , details should displayed using binding. on panel displaying details using datacontext , bind item selected on grid. and, on grid, communicate item has been selected using selectedvalue.

below sample should give thought what's relation between views.

<window ... xmlns:view="clr-namespace:sampleproject.view" ... /> <grid> <grid.rowdefinitions> <rowdefinition height="*"/> <rowdefinition height="*"/> </grid.rowdefinitions> ... <!-- let's assume sec view defined in view folder --> <view:detailsview datacontext="{binding selecteditem, updatesourcetrigger=propertychanged, mode=twoway}"/> <datagrid itemssource="{binding items, updatesourcetrigger=propertychanged, notifyonsourceupdated=true}" selectedvalue="{binding selecteditem, updatesourcetrigger=propertychanged}" > ...

the items collection of products want display in datagrid. should implemented in viewmodel of main view. selecteditem property on viewmodel.

note sample give thought what's construction of solution might it's far finish solution. still, hope help understand how go on project.

main point communication between panels done utilize of binding datacontext (on detailsview) , selectedvalue (on grid).

java - How to add css-keyframes to vaadin components? -

java - How to add css-keyframes to vaadin components? -

i'd add together keyframe-animation vaadin label component: background should create colored transition red yellow.

but bg color not alter in way. missing anything?

private label label = new label("background reddish fading"); lable.setcss("red");

css:

.v-label-red { @include red; }

keyframe:

@-webkit-keyframes reddish { {background: red;} {background: yellow;} } @keyframes reddish { {background: red;} {background: yellow;} }

be sure have @keyframes out of main @mixin of theme. next .v-label-red needs background set (most same to in keyframes , needs time handle (now goes white -> reddish -> yellowish -> white in no time. here example, should bring on right track:

css

@import "../reindeer/reindeer.scss"; @keyframes keyframe1 { {background: red;} {background: yellow;} } @keyframes keyframe2 { {background: yellow;} {background: red;} } @mixin app { @include reindeer; .keyframe1 { background: yellow; -webkit-animation: keyframe1 1s linear; -moz-animation: keyframe1 1s linear; -ms-animation: keyframe1 1s linear; animation: keyframe1 1s linear; } .keyframe2 { background: red; -webkit-animation: keyframe2 1s linear; -moz-animation: keyframe2 1s linear; -ms-animation: keyframe2 1s linear; animation: keyframe2 1s linear; } }

vaadin ui code (groovy)

@vaadinui @theme('app') @compilestatic class appui extends ui { final static string k1 = 'keyframe1' final static string k2 = 'keyframe2' @override protected void init(vaadinrequest vaadinrequest) { final layout = new verticallayout() layout.setspacing(true) layout.setmargin(true) final headline = new label('hello world') headline.addstylename(k1) final button = new button("toggle", { if (headline.stylename.contains(k1)) { headline.addstylename(k2) headline.removestylename(k1) } else { headline.addstylename(k1) headline.removestylename(k2) } } button.clicklistener) layout.addcomponents(headline, button) setcontent(layout) } }

this code fade label on loading , fade between 2 states on button clicks.

xamarin - Android Setting New default home in code -

xamarin - Android Setting New default home in code -

i have app want set default home screen, i'm running unusual problem.

i have setting allows user select default home screen.

i utilize next code allow them select default activity:

intent selector = new intent(intent.actionmain); selector.addcategory(intent.categoryhome); selector.addcategory(intent.categorydefault); selector.setcomponent(new componentname("android", "com.android.internal.app.resolveractivity")); startactivity(selector);

with no default set, run code , select app default , tell utilize that.

now, run code again, , tell utilize different activity (not mine) , utilize it.

the problem is, never switches different if default set.

i've seen other applications allow this, i'm missing something, don't know what.

i'm testing on samsung galaxy s4 api level set 14.

ok, found reply question.

the reply here: http://www.trustydroid.com/2014/05/19/force-show-default-app-chooser-dialog/

the 1 thing should maintain in mind component name must correct. apparently under api14, ignores component (and acts works) if class name not correct. goes through motions of enabling component, launching chooser, disabling component. however, never saves new default.

after tried compiling under api19, os threw exception lead me prepare issue having working (which wrong class name).

once had straightened out, did wanted.

for completeness sake, here code:

create fakeactivity this:

[activity(label = "fakelauncher", enabled = false)] [intentfilter(new[] { intent.actionmain }, categories = new[] { intent.categoryhome, intent.categorydefault })] public class fakelauncher : activity { protected override void oncreate(bundle bundle) { base.oncreate(bundle); // create application here } }

then ever want alter default home run code:

componentname componentname = new componentname(application.packagename, "<fake activity class name>"); packagemanager.setcomponentenabledsetting(componentname, android.content.pm.componentenabledstate.enabled, android.content.pm.componentenableoption.dontkillapp); intent tempintent = new intent(intent.actionmain); tempintent.addcategory(intent.categoryhome); startactivity(tempintent); packagemanager.setcomponentenabledsetting(componentname, android.content.pm.componentenabledstate.disabled, android.content.pm.componentenableoption.dontkillapp);

php - Mongo Update Speed -

php - Mongo Update Speed -

i have script when run on local scheme runs when running on production scheme runs much slower. have confirmed php profiler slow-down happening in update method on mongocollection object. have copied php software (binary , modules) production scheme local scheme create sure isn't due difference in machine/network. running production php software on local scheme runs slow. problem not machine or network. since same script not script. points 1 of 3 possibilities:

difference in php version difference in mongo driver version difference in configuration

the script in question iterates through records in collection , makes update each one. update has write concern set 0 speed more of import knowing executed successfully. php profiler stopped providing info 1 time called update (since update implemented in c). turned next strace see if scheme calls help explain difference in speed. loop updates beingness issued has next strace output on fast system:

notice have added scheme calls. looks checking reply me indicates it's not using write concern 0. major difference between 2 php installations fast 1 using driver 1.4.5 while slow 1 using 1.5.3.

i compared update code both versions. in 1.4.5 it seems send message , return. on other hand looking @ 1.5.3 it sends message gets reply. don't see skipping checking reply if write status 0. if follow code extracts reply can see calls these 2 additional scheme calls.

can understand improve help me figure out how code running fast in production. on fast php install (mongo driver 1.4.5) script executes in 2-3 minutes. on slow scheme (mongo driver 1.5.3) killed after 30 minutes because tired of waiting. knows how long have taken done.

(note: updated original reply after research)

the new write operation commands came in 2.6 , hence in utilize between supported driver (php 1.5+) , mongodb server (2.6+) mean new semantics of w=0 writes in play. means server waits operation finish before sending response (that is, difference between w=0 , w=1 w=0 omits error details). driver still waits response before returning phone call (i.e. no longer fire , forget).

you can see in mongodb shell also, , official way around utilize new bulk api. although know 1.5 driver fall legacy write operations when connecting 2.4 , below server, there no way forcefulness behavior in php driver.

javascript - ReceiveMessage event showing data as undefined -

i have iframe in there javascript function:

function callparent(){ parent.postmessage('closemodal','*'); homecoming true; }

and other javascript function in main page:

$(window).on('message',function(e){ console.log(e); });

it's printing e in e.data it's giving undefined. expecting info string 'closemodal'.

how message string iframe?

the info you're passing in

e.originalevent.data

so on main page:

$(window).on('message',function(e){ console.log(e.originalevent.data); });

as pointy commented jquery creates own event object.

if not using jquery have had

window.onmessage = function(e){ console.log(e.data); };

i horrible regular expressions , new url rewrite module in iis please bear me...

i have scenario have 1-2 pages need redirected specific location , protocol (https).

desired url

https://www.domain.com/specific/location/mypage.aspx

i need create sure users hitting specific url when trying access page. of below should redirect user "desired" url:

http://www.domain.com/specific/location/mypage.aspx http://domain.com/specific/location/mypage.aspx https://domain.com/specific/location/mypage.aspx http://www.anotherdomain.com/specific/location/mypage.aspx http://anotherdomain.com.com/specific/location/mypage.aspx https://anotherdomain.com.com/specific/location/mypage.aspx

i need happen page , 1 other page , need create sure these pages beingness redirected ssl, rest of site should redirected http version if user types in https. how can accomplish this, need more 1 rule, etc?

any help appreciated.

thankfully, isn't complicated looks. when creating rules using iis url rewrite module, "url" in match tag looking @ after host name. doesn't see domain.com.

so, in web.config, within system.webserver section, in rewrite section:

<rule name="redirect specific location" enabled="true" stopprocessing="true"> <match url="specific\/location\/mypage\.aspx"/> <action type="redirect" url="https://www.domain.com/specific/location/mypage.aspx"/> </rule>

that way url coming in ends specific/location/mypage.aspx redirected, no matter hostname is.

thanks in advance.

if have coordinates easy. first create cv::mat , set white.

cv::mat image; image.setto(cv::scalar(255,255,255));

then if have begin , end coordinates can draw line using opencv line function.

cv::line(image, cv::point(initial_coords.x, initial_coords.y), cv::point(end_coords.x, end_coords.y), cv::scalar(0,0,255));

finally w utilize puttext function

cv::puttext(image, "text", cv::point(coords.x, coords.y), cv::font_hershey_script_simplex, 2, scalar::all(255), 3,8);

if need erase window before adding new things utilize 1 time again

i building database of skills , in origin thinking need title param them added required param. rid of title param can create new skills , description. right there error because looking :title. here controller:

class skillscontroller < applicationcontroller def index @skills = skill.all end def show @skills = skill.all end def new @skills = skill.all end def create @skills = skill.new(skill_params) if @skills.save redirect_to :action => 'index' else @skills = skill.find(:all) render :action => 'new' end end def edit @skills = skill.find(params[:id]) @skills = skill.find(:all) end def update @skills = skill.find(params[:id]) if @skills.update_attributes(params[:skill]) redirect_to :action => 'show', :id => @skills else @skills = skill.find(:all) render :action => 'edit' end end def delete skill.find(params[:id]).destroy redirect_to :action => 'index' end def show_skills @skills = skill.find(params[:id]) end end private def skill_params params.require(:skill).permit(:attribute_1, :attribute_2, :attribute_3) end

and here error when seek , submit new skill:

activerecord::statementinvalid in skillscontroller#create sqlite3::constraintexception: skills.title may not null: insert "skills" ("created_at") values (?)

i think easiest way bypass issue create skill.title not required not sure how prepare it. post /new form if helps:

<h1>add new skill</h1> <%= form_tag ({action: "create"}) %> <p><label for="skill">skill</label>: <%= text_field 'skill', 'title' %></p> <p><label for="skill_description">description</label><br/> <%= text_area 'skill', 'description' %></p> <%= submit_tag "create" %> <% end %> <%= link_to 'back', {:action => 'index'} %>

i tried getting rid of 'title' line , made more problems. maintain messing code , researching , give thanks knows issue. cheers , 1 time again stackers!!!

looks created title column not null constraint, database won't allow record created without title.

if don't need it, should drop column database.

create migration:

bundle exec rails generate migration remove_title_from_skills

edit migration file created , add:

def alter remove_column :skills, :title end

run migration:

bundle exec rake db:migrate

remove other references :title in application.

and undesired columns create them visible = false datagridview properties came problem if want specify info (rows) fill in datagridview such applying status like: fill info in datagridview isactive = 1 can still utilize above code modifications or have write sql query , fill datagridview manually ?

after searching , trying tons of codes got next in simplest code: in code above comment out lastly line datagridview1.datasource = schl.studentinfo.defaultview; or replace following

dataview dv = new dataview(schooldataset.studentinfo, "isactive = 'false'", "id", dataviewrowstate.currentrows);

the specific lines failing, error occurs when mcontext used.

@override public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); fragval = getarguments() != null ? getarguments().getint("val") : 1; mhandler = new handler(); // initializes bluetooth adapter. api level 18 , above, reference // bluetoothadapter through bluetoothmanager. final bluetoothmanager bluetoothmanager = (bluetoothmanager) mcontext.getsystemservice(context.bluetooth_service); mbluetoothadapter = bluetoothmanager.getadapter(); }

you have not initialized mcontext , null. invoking method on null reference causes npe.

in fragment, utilize getactivity() reference hosting activity can used context. (caveat: when attached activity. works in oncreate() comes after onattach().)

so, replace

mcontext.getsystemservice()

with

getactivity().getsystemservice()

random - Split an array into chaotic sub-arrays? -

random - Split an array into chaotic sub-arrays? -

there need split info array consisting of n rows , m columns s non-intersecting parts of (approximately) equal size.

realistically n*m not divisible s have work blocks of size floor(n*m) , ceil(n*m). @ moment to the lowest degree of concerns.

the essential required property every block structurally disconnected wholeness of info in sense neither big chunks of globally adjacent elements belong same block nor checker-board style splitting.

what suggest? should turn randomness or there neat structures suitable in situation?

i've found myself idly mulling on during snatched periods of downtime, , seems there should few ways it; depends on want achieve. here's i've been dreaming up, in case it's useful.

as understand this, you'd split n x m array i equal chunks, n , m unknown, , without adjacent elements sharing set.

firstly, four colour theorem tells can 4 sets; might worth seeing if there's existing algoritm working these out array. on other end of scale, can trivially n x m groups, assigning each element it's own singleton set.

how approach rather depends on you'd minimise - whether want smallest number of groups i, example. if wasn't issue, seek following:

looking @ n alone, if n even, split array sets of size n/2, create n/2 sets - 1 containing 1st element of each group, 1 containing 2nd etc. these contain non-consecutive elements. if n odd, create singleton set consisting of nth element, , proceed above remainder.

in 1 - dimensional case, give n/2 sets of size 2, potential set of size 1. work 2 dimensions well, dividing both n , m above.

as said, isn't reply looking for, hope might help promote farther investigation - replace odd / check 1 highest mutual factor or prime decomposition, example. might worth asking on math overflow.

i can write pseudocode (or python) how above might possible, if useful.

i figure it's matter of creating new var's , writing function add together 6 existing img class (e.g. s1 becomes s7, etc.) that's guess , said, if that's right i'm still in embryonic stages of js coding.

your javascript swap image works fine, issue first part of script. commented out in fiddle , worked fine. there improve ways (sliding divs within container, build elements in javascript , append them frames on page - give pinterest style effect of loading new elements @ bottom) - depends on how want handle suggestion using jquery add together or remove elements dom.

//var s7= new image(); //img.src=url('https://encrypted-tbn0.gstatic.com/images?q=tbn:and9gcrhc9vk1u5yc5rwmhuk9ai2rgidcsh-wxpt-aleqm9onxi9xbn9da'); $(document).ready(function () { $('#prev').click(function () { $('.s1').css('background-image', 'url("http://i1281.photobucket.com/albums/a514/jshweky/gourmade%20to%20order/img_1483_zpsc4ca87cf.jpg")'); }); });

also, here alternate syntax .css() allow alter more 1 property of elements @ time (you need utilize .html() function alter text in next element too):

$('.s1').css({backgroundimage : 'url("http://i1281.photobucket.com/albums/a514/jshweky/gourmade%20to%20order/img_1483_zpsc4ca87cf.jpg")', backgroundsize : "cover"}); });

php - posts order by title second word -

php - posts order by title second word -

this mutual question, haven't been able find straightforward reply to. want generate list of custom post type titles. im using 'orderby' => 'title' have them display alphabetically. titles names , lastly names , want sort lastly name. know create meta fields seperated first , lastly names , order lastly name field. i'd see if there no method explode 'title' , pass sec word in `orderby'.

this basic code:

<?php // 'actors' post type $args = array( 'post_type' => 'actors', 'orderby' => 'title', 'order' => 'asc', 'nopaging' => true, 'cache_results' => false, 'update_post_meta_cache' => false ); $loop = new wp_query($args); while($loop->have_posts()): $loop->the_post(); echo '<li><img src="' . get_post_meta(get_the_id(),'_dtm_small_image', [0]) . '"><span>' . get_the_title() . '</span></li>'; endwhile; wp_reset_query(); ?>

iv'e tried to:

$gettitle = get_the_title(); $lastname = explode(" ", $gettitle);

and alter 'orderby' => $lastname[1], . doesnt work. there no way utilize sec word in title sort posts?

you can't loop, wordpress doesn't have option.

what can do, it's split title , create array.

$people = array(); while($loop->have_posts()): $loop->the_post(); list($firstname, $lastname) = explode(" ", get_the_title() ); // can utilize list, since said that's first , lastly name on title. $people[] = $lastname; endwhile; wp_reset_query(); sort($people); // sort array asc. note: can create function sort sort or rsort, on input foreach ($people $last) { echo $last, "<br />"; // echo lastly name }

this not efficient, works. should consider adding 2 fields wordpress.

osgi - when using gogo gosh scripts, how do I get print outs from all commands -

i'm trying automate provisioning , searching of service speed testing of changes osgi system. utilize maven pax:provision set environment various repositories.

i have commands load info xml files , commands search services. search commands homecoming string describing results.

i've provision.tsl file commands load osgi environment , search.tsl file runs search commands. in search.tsl have list of search command, each various tables i've loaded. e.g.

echo doing searching searchcell sometable somevalue searchcolumnname echo search someothertable searchcell someothertable someothervalue searchcolumnname echo search yetanothertable searchcell yetanothertable yetsomeothervalue searchcolumnname

however, when run search command e.g.

osgi> gosh search.tsl

i result lastly command in file. echo works normal though , looks like.

doing searching search someothertable search yetanothertable homecoming results searchcell yetanothertable

is expected behaviour gosh?

the gosh console automatically prints value of each interactive command.

this makes appear searchcell command printing result, when in fact returning string, gogo prints.

this doesn't work in scripts, either need recode searchcell command print stdout, or explicitly print each result in script:

echo doing searching echo (searchcell sometable somevalue searchcolumnname) echo search someothertable echo (searchcell someothertable someothervalue searchcolumnname)

time - How to convert Milliseconds to "X mins, x seconds" in Java? -

time - How to convert Milliseconds to "X mins, x seconds" in Java? -

i want record time using system.currenttimemillis() when user begins in program. when finishes, subtract current system.currenttimemillis() start variable, , want show them time elapsed using human readable format such "xx hours, xx mins, xx seconds" or "xx mins, xx seconds" because not take hour.

what's best way this?

since 1.5 there java.util.concurrent.timeunit class, utilize this:

string.format("%d min, %d sec", timeunit.milliseconds.tominutes(millis), timeunit.milliseconds.toseconds(millis) - timeunit.minutes.toseconds(timeunit.milliseconds.tominutes(millis)) );

(thanks @damian comments) if want add together leading 0 values 0-9, do:

string.format("%02d min, %02d sec", timeunit.milliseconds.tominutes(millis), timeunit.milliseconds.toseconds(millis) - timeunit.minutes.toseconds(timeunit.milliseconds.tominutes(millis)) );

for java versions below 1.5 or systems not back upwards timeunit class (such android before api version 9), next equations can used:

int seconds = (int) (milliseconds / 1000) % 60 ; int minutes = (int) ((milliseconds / (1000*60)) % 60); int hours = (int) ((milliseconds / (1000*60*60)) % 24); //etc...

from time time, "could not connect. many connections" error. tends happen when have google bot scanning website.

this problem seems have started ever since upgrading mysqli mysql. there advice on how ensure connections closed?

thanks

you need increment number of connections mysql server (the default 100 , typically each page load consumes 1 connection)

edit /etc/my.cnf

max_connections = 250

then restart mysql

service mysqld restart

ios - UITableview create alphabetic indexing from data array -

ios - UITableview create alphabetic indexing from data array -

i have nsmutablearray populated sqlite query returns want display in uitableview in alphabetical order.

i know want display letter indexs see in contacts application etc.

however not sure how set indexs , create sections array each sections next letter in alphabet.

how go taking array , getting sections , indexs needed?

let's array (nsmutablearray myarray) letters looks this:

( { headertitle = v; rowvalues = ( { id = 60; name = "valley of giants (2)"; "real_name" = "valley of giants"; "wine_count" = " (2)"; } ); }, { headertitle = r; rowvalues = ( { id = 47; name = "rothbury estate (6)"; "real_name" = "rothbury estate"; "wine_count" = " (6)"; }, { id = 48; name = "rouge homme (4)"; "real_name" = "rouge homme"; }, { id = 45; name = "rawson\u2019s retreat (7)"; "real_name" = "rawson\u2019s retreat"; }, { id = 46; name = "rosemount estate (36)"; "real_name" = "rosemount estate"; } ); },

in table view, set number of sections

- (nsinteger)numberofsectionsintableview:(uitableview *)tableview { homecoming [myarray count]; }

number of rows in section:

- (nsinteger)tableview:(uitableview *)tableview numberofrowsinsection:(nsinteger)section{ homecoming [[[myarray objectatindex:section] objectforkey:@"rowvalues"] count]; }

section title

-(nsstring *)tableview:(uitableview *)tableview titleforheaderinsection:(nsinteger)section{ homecoming [[myarray objectatindex:section] valueforkey:@"headertitle"]; }

then within cellforrowatindexpath can access info this

- (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath{ nsstring *name= [[[[myarray objectatindex:indexpath.section] objectforkey:@"rowvalues"] objectatindex:indexpath.row] valueforkey:@"name"]; // , create cell do... }

if need sort array in alphabetical order can like:

nssortdescriptor *descriptor = [[nssortdescriptor alloc] initwithkey:@"headertitle" ascending:yes]; [myarray sortusingdescriptors:[nsarray arraywithobject:descriptor]];

c# 4.0 - C# explicit cast - from collection of KeyValuerPair to Dictionary -

c# 4.0 - C# explicit cast - from collection of KeyValuerPair to Dictionary -

i have list of keyvaluepairs. utilize todictionary.

however noted error message (shown below) has explicit cast, implies can cast list dictionary<...>. how can this?

cannot implicitly convert type 'system.linq.iorderedenumerable<system.collections.generic.keyvaluepair<int,string>>' 'system.collections.generic.dictionary<int, string>'. explicit conversion exists (are missing cast?)

sample code:

dictionary<int, string> d = new dictionary<int, string>() { {3, "c"}, {2, "b"}, {1, "a"}, }; var s = d.orderby(i => i.value); d = s;

implies can cast list dictionary

well, implies cast valid @ compile-time. doesn't mean work @ execution time.

it's possible code work:

iorderedenumerable<keyvaluepair<string, string>> pairs = getpairs(); dictionary<string, string> dictionary = (dictionary<string, string>) pairs;

... if value returned getpairs() class derived dictionary<,> implemented iorderedenumerable<keyvaluepair<string, string>>. it's unlikely that's actually case in normal code. compiler can't stop trying, won't end well. (in particular, if code in question , standard linq objects, fail @ execution time.)

you should stick todictionary... although should aware you'll lose ordering, there's no point in ordering start with.

to show code in question:

dictionary<int, string> d = new dictionary<int, string>() { {3, "c"}, {2, "b"}, {1, "a"}, }; var s = d.orderby(i => i.value); d = (dictionary<int, string>) s;

that compiles, fails @ execution time predicted:

unhandled exception: system.invalidcastexception: unable cast object of type 'system.linq.orderedenumerable`2[system.collections.generic.keyvaluepair`2[system.int32,system.string],system.string]' type 'system.collections.generic.dictionary`2[system.int32,system.string]'. @ test.main()

as bit of background, can always cast interface type non-sealed class ("target"), if type doesn't implement interface, because it's possible class derived "target" implement interface.

from section 6.2.4 of c# 5 specification:

the explicit reference conversions are:

... from class-type s interface-type t, provided s not sealed , provided s not implement t. ...

(the case s does implement t covered implicit reference conversions.)

if seek implicitly convert value , there's no implicit conversion available, there's explicit conversion available, compiler give warning in question. means can prepare compiler-error cast, need aware of possibility of failing @ execution time.

here's example:

using system; class test { static void main() { iformattable x = getobject(); } static object getobject() { homecoming datetime.now.second >= 30 ? new object() : 100; } }

error message:

test.cs(7,26): error cs0266: cannot implicitly convert type 'object' 'system.iformattable'. explicit conversion exists (are missing cast?)

so can add together cast:

iformattable x = (iformattable) getobject();

at point, code work half time - other half, it'll throw exception.

my code using read_line_to_codes/2 , read_stream_to_codes/2 in order read user_input. how these reads organized:

main :- read_line_to_codes(user_input, [a]), read_line_to_codes(user_input, b), /* parsing happens here */ read_stream_to_codes(user_input, c), /* more parsing happens here , code goes on */

i compiling programme using next command:

swipl -q -t main -o programme -c program.pl

the programme runs fine, due reads in main, output |:|: characters (the swipl console shows |: whenever user has input something). when remove i/o code program, runs without outputting characters.

is there way rid of behavior?

you have utilize prompt1/1 predicate set prompt next line or prompt/2 alter prompt message globally.

e.g. using prompt1/1:

?- read_line_to_codes(user_input, l). |: test l = [116, 101, 115, 116]. ?- prompt1(''), read_line_to_codes(user_input, l). test l = [116, 101, 115, 116].

or, using prompt/2:

?- prompt(old, 'give me: '). old = '|: '. ?- read_line_to_codes(user_input, l). give me: abc l = [97, 98, 99].

i know can generating new erd each time want add together table 5 tables. there work-around don't have reverse engineer each time want add together new table thinks related 5 tables.

thanks.

try reverse engineering science new model , save that. open main model , take file -> include model include other model.

algorithm - Efficiently filling empty cells in 3D matrix -

algorithm - Efficiently filling empty cells in 3D matrix -

i have 3d "cubical" matrix, cells filled , others empty. closed part enclosed filled cells represents hollow shape. example, matrix have cells filled in such way form surface of hollow sphere. now, want efficient way fill interior of sphere: if cell c0 surrounded in directions filled cells (filled cell in direction need not immediate neighbour of c0), fill c0.

a naive way next :-

for each cell, scan in +x, -x, +y, -y, +z, -z direction, , see if encounter filled cell in each , every direction.

if filled cell encountered in each , every direction, fill cell (as part of interior of shape).

if reach end of grid in 1 direction without encountering filled cell, cell under consideration not interior shape, , should remain unfilled.

the complexity of above approach o(n^4), dimension of 3d grid n*n*n.

an optimization follows :-

if unfilled cell c[x][y][z], encountered 1 filled cell each in 6 directions, not c[x][y][z] needs filled, guaranteed cells scanned (i.e. {in +x direction, cells c[x][y][z], c[x+1][y][z], c[x+2][y][z], ..., till first filled cell}, -x, +y, -y, +z, -z direction) must part of interior of shape, , hence must filled.

another follows :-

if unfilled cell c[x][y][z], not encounter filled cell in, say, +x direction, not c[x][y][z] remain unfilled, guaranteed cells scanned (i.e. in +x direction, cells c[x][y][z], c[x+1][y][z], c[x+2][y][z], ..., till end of grid) must part of exterior , hence, must remain unfilled.

can suggest more efficient approach problem? simple optimizations above, might not cut down order of time complexity, welcome.

wpf - TaskFactory New UI Creation -

wpf - TaskFactory New UI Creation -

how create new ui element using taskfactory? when seek next error :

the calling thread must sta, because many ui components require this.

example code

dim txtboxlist new list(of textbox) sub startthread() dim ts taskscheduler = taskscheduler.fromcurrentsynchronizationcontext() task.factory.startnew(sub() createcontrol(), ts) end sub sub createcontrol() dim txtbox new textbox dispatcher.begininvoke(sub() txtboxlist.add(txtbox)) end sub

if you're working wpf, need leave behind , notions might have learned ancient technologies , understand , encompass the wpf mentality.

basically, never need create or manipulate ui elements in procedural code in wpf. instead, wpf lends heavily utilize databinding.

the wpf threading model not allow create or manipulate instances of ui elements in background threads, , add together them visual tree created "main" ui thread.

anyways, there 0 need such thing, because creating ui elements in cases trivial task can (and must) performed ui thread.

rather worrying visual tree, should concentrate on having data loaded in background threads, , passed datacontext ui can display info accordingly.

this little illustration uses itemscontrol display list of users, loaded asynchronously in background thread , dispatched ui thread display:

<window x:class="wpfapplication7.asyncitemscontrol" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> <itemscontrol itemssource="{binding}"> <itemscontrol.itemtemplate> <datatemplate> <border background="lightgray" borderbrush="black" borderthickness="1" margin="2"> <stackpanel> <textblock text="{binding lastname}" margin="2"/> <textblock text="{binding firstname}" margin="2"/> </stackpanel> </border> </datatemplate> </itemscontrol.itemtemplate> </itemscontrol> </window>

code behind:

public partial class asyncitemscontrol : window { public asyncitemscontrol() { initializecomponent(); var dispatcher = taskscheduler.fromcurrentsynchronizationcontext(); task.factory.startnew(() => getusers()) .continuewith(x => datacontext = x.result,dispatcher); } public list<user> getusers() { // pretend method calls web service or database retrieve data, , takes 5 seconds response: thread.sleep(5000); homecoming new list<user> { new user() {firstname = "marty", lastname = "mcfly"}, new user() {firstname = "emmett", lastname = "brown"}, new user() {firstname = "bufford", lastname = "tannen"} }; } }

data item:

public class user { public string lastname { get; set; } public string firstname { get; set; } }

result:

notice illustration uses databinding , not create or manipulate ui elements in procedural code, rather operates simple user class simple string properties.

also notice during 5 seconds "load" time, ui responsive because actual work beingness performed background thread.

this approach allows greater separation between ui , info allows much greater scalability , customizability of ui without having alter underlying business / application logic.

notice how itemscontrol takes care of creating , rendering appropiate ui elements needed display 3 info items. actual definition of "how each item looks" datatemplate.

i recommend reading material linked thoughout reply more in-depth understanding of how wpf works in general.

side note: if you're targetting c# 5.0 can leverage async / await , create code cleaner removing task based stuff. i'm on c# 4.0 feature not available me.

wpf rocks. re-create , paste code in file -> new project -> wpf application , see results yourself.

let me know if need farther help.

the documentation doesn't http://hackage.haskell.org/package/http-conduit-1.2.1/docs/network-http-conduit.html

note docs request:

the constructor info type not exposed. instead, should utilize either def method retrieve default instance, or parseurl build url, , use records below create modifications.

so can configure request using number of record names. in case need requestheaders , requestbody. here example:

{-# language overloadedstrings #-} import data.text (text) import qualified data.aeson aeson import qualified data.map map import network.http.conduit main :: io () main = request <- parseurl "http://example.com" res <- withmanager $ httplbs $ configurerequest request print res configurerequest r = r { method = methodpost, requestheaders = ("content-type", "application/json") : requestheaders r, requestbody = requestbodylbs (aeson.encode $ map.fromlist [("aaa" :: text, "bbbccsddd" :: text)]) }

How to change String Array to ArrayList in java -

How to change String Array to ArrayList in java -

here original code has defined string-array (25). working perfectly. don't need define 25. instead, used arraylist. please check code.

using string of array:

public string[] getemailaddr(string straccountnbr) throws exception { string strquery2 = null; resultset rs = null; preparedstatement ps = null; string[] emailaddress = new string[25]; int i=0; strquery2 = "select c.emailaddress emailaddress" + " customeremailid c " + "where c.accountnbr = ? " ; logmsg("strquery2: "+strquery2); ps = getdbconn().preparestatement(strquery2); ps.setstring(1, straccountnbr); rs = ps.executequery(); while(rs.next()) { emailaddress[i]=(rs.getstring("emailaddress")); logmsg("emailaddress[i]"+" "+i+": "+emailaddress[i]); i=i+1; } homecoming emailaddress; }

here, need alter string-array arraylist. tried this,

public string[] getemailaddr(string straccountnbr) throws exception { string strquery2 = null; resultset rs = null; preparedstatement ps = null; //newly tried // arraylist<string> strarremailids = new arraylist<string>(); string[] emailaddress= new string[strarremailids.size()]; strarremailids.toarray(emailaddress); //newly tried // int i=0; strquery2 = "select c.emailaddress emailaddress" + " customeremailid c " + "where c.accountnbr = ? " ; logmsg("strquery2: "+strquery2); ps = getdbconn().preparestatement(strquery2); ps.setstring(1, straccountnbr); rs = ps.executequery(); while(rs.next()) { emailaddress[i]=(rs.getstring("emailaddress")); logmsg("emailaddress[i]"+" "+i+": "+emailaddress[i]); i=i+1; } homecoming emailaddress; }

email ids database instead of example.com.

but getting java.lang.arrayindexoutofboundsexception: 0 error in line. emailaddress[i]=(rs.getstring("emailaddress"));

please help!

this not how utilize arraylist.

first, need write:

list<string> strarremailids = new arraylist<>();

so, programme interface , utilize java 7 diamond operator.

next, remove index i. don't need this.

finally, do:

emailaddress.add(rs.getstring("emailaddress"));

to convert string[] can do:

string[] arr = emailaddress.toarray(new string[emailaddress.size()]);

here suggestion final code:

public string[] getemailaddr(string straccountnbr) throws exception { final list<string> emailaddress = new arraylist<>(); final string strquery2 = "select c.emailaddress emailaddress" + " customeremailid c " + "where c.accountnbr = ? "; seek (final preparedstatement ps = getdbconn().preparestatement(strquery2)) { ps.setstring(1, straccountnbr); seek (final resultset rs = ps.executequery()) { while (rs.next()) { emailaddress.add(rs.getstring("emailaddress")); } } } homecoming emailaddress.toarray(new string[emailaddress.size()]); }

i have removed pointless assignments null. have added try-with-resources blocks close external resources, code 1 massive memory leak.
