How to use aysnc module in node.js to loop over two arrays -

How to use aysnc module in node.js to loop over two arrays -

i want loop on array , write info database. code below shows how in non-async way loop. know not preferred way of doing it.

for(var x = 0;x < tt.matches.length;x++) //match each player match , playerid tournament tree { if(tt.matches[x].p[0] !== -1) { var tmid = json.stringify(tt.matches[x].id); player.update({ _id : grupd.players[y] },{ tournamentmatchid : tmid, treeid : tt.matches[x].p[0], opponent : tt.matches[x].p[1] },{ safe : true }, function (err) { if(err) { console.log(err); } }); y++; } if(tt.matches[x].p[0] === -1) { byes++; } if(tt.matches[x].p[1] !== -1) { var tmid = json.stringify(tt.matches[x].id); player.update({ _id : grupd.players[y] },{ tournamentmatchid : tmid, treeid : tt.matches[x].p[1], opponent : tt.matches[x].p[0] },{ safe : true }, function (err) { if(err) { console.log(err); } }); y++; } if(tt.matches[x].p[1] === -1) { byes++; } }

i need perform following, 1 time again shown in 'traditional way'.

for(var x = 0;x < plyrs.length;x++) { var nextmatch = json.stringify(tt.upcoming(plyrs[x].treeid)) ; player.update({ _id : plyrs[x]._id },{ tournamentmatchid : nextmatch },{ safe : true }, function (err) { if(err) { console.log(err); } }); }

you keeping counter of open db calls, calling next phase of programme when of calls have returned. see below.

there's theoretical hole in approach though, if of player.update() calls homecoming before process.nexttick completion status may triggered early.

var activecalls = 0; for(var x = 0;x < tt.matches.length;x++) //match each player match , playerid tournament tree { if(tt.matches[x].p[0] !== -1) { var tmid = json.stringify(tt.matches[x].id); activecalls++; player.update({ _id : grupd.players[y] },{ tournamentmatchid : tmid, treeid : tt.matches[x].p[0], opponent : tt.matches[x].p[1] },{ safe : true }, function (err) { activecalls--; if(err) { console.log(err); } if ( activecalls == 0 ) donextthing() }); y++; } if(tt.matches[x].p[0] === -1) { byes++; } if(tt.matches[x].p[1] !== -1) { var tmid = json.stringify(tt.matches[x].id); activecalls++; player.update({ _id : grupd.players[y] },{ tournamentmatchid : tmid, treeid : tt.matches[x].p[1], opponent : tt.matches[x].p[0] },{ safe : true }, function (err) { activecalls--; if(err) { console.log(err); } if ( activecalls == 0 ) donextthing() }); y++; } if(tt.matches[x].p[1] === -1) { byes++; } }

php - substr not working correctly? -

i creating forum, , working on bbcode section. bbcode works, implementing emoticon system. syntax looks this: [e]:)[/e]

i made string testing purposes:

[b]hello world[/b] [i]i having fun[/i] [e]:)[/e] how doing today?! <3[color=blue]:d[/color]

and returning not want. here returning:

:)[/e] how doing today?! <3[color=bl

this code:

function bbcode($str) { if (strpos($str, '[e]')!==false && strpos($str, '[/e]')!==false) { $f = strpos($str, '[e]') + 3; $s = strpos($str, '[/e]'); $emote = substr($str, $f, $s); } homecoming $emote; }

note $f , $s returning right positions, 45 , 47, substr not cutting string correctly. why , how can prepare it?

"string substr ( string $string , int $start [, int $length ] )

returns portion of string specified start and length parameters."

$emote = substr($str, $f, $s - $f);

so here problem, given code, added before please input name ignored, , automatically first instruction run(without first checking if x 5, input name, instructions prior run. if first line of programme printf, ignored , inquire input print printf statement though first. please help

int main(int argc, char** argv) { char val[70]; int x=3; if(x>5) { if(write(1, "please input name", 22)!=22) { homecoming -1; } if(read(0, val, 36) < 0) {} if(write(1, val, 36)!=36) {} } }

printf works on stdout file*. read() , write() calls work straight on file descriptors.

a file* buffered, meaning stuff printf resides in buffer in programme until flushed. while write() sends info straight operating system, without buffering in application.

so flush file* buffer create output appear:

int main(int argc, char** argv) { char val[70]; int x=3; printf("hello"); fflush(stdout);

and if stdout terminal, auto flushed when write newline, e.g. printf("hello\n");

HTML/CSS Div Extending Beyond Its Closing Tag -

on web page i'm creating, page dynamically generated php-based cms. cms fetches info page database, echoes right html tags etc onto page.

the problem have reason browser extending div beyond it's closing tag.

ie: though can see tag closes, browser doesn't appear to, styling applied within div beingness applied whole page.

below html output. (this extract of page, , header div 1 that's persisting).

<div id="header"> <table> <tr> <td style="width: 10%;"> <img style="height: 120px; width: 101px;" src="img" alt="some alt"> </td> <td> <h2>heading</h2> <h3>subhead</h3> </td> </tr> <table> </div> <div id="menubar">

i've included opening of next div.

if seek , style h2 , h3 within of div, of h2 , h3 tags on page affected. here's css:

#header h2 { font-size: 24pt; font-weight: 900; color: #776f65; letter-spacing: 0; line-height: 0; } #header h3 { font-weight: 900; color: #776f65; letter-spacing: 0; padding-left: 35px; }

and finally, here's php code utilize generate html output:

echo('<div id="header">'); // header element begins here while($row = mysql_fetch_array($getheaderelements)) { echo($row['content']); } echo('</div>'); // end header element.

does know why unusual behavior occurring?

regards, ben.

the "end" tag <table> start tag table.

this error cause of problem.

combinatorics - Find vector elements that sum up to specific number in MATLAB -

combinatorics - Find vector elements that sum up to specific number in MATLAB -

let consider have vector vec.

is ther way find vector elements can grouped sum given number num in matlab?

for illustration if vec = [2 5 7 10] , num = 17

the requested algorithm should provide reply subvectors [2 5 10] , [7 10] sum given num.

here way solve using conbntns, function mapping toolbox retrieves possible combinations of set of values (if don't have toolbox, can utilize combinator fex). so, vector a, example, we'll find possible combination of given length (1 length of a) sum them , see equal num=17:

num=17; a=[2 5 7 10]; ii=1:numel(a) b=combntns(a,ii); c=sum(b,2); d=find(c==num); if ~isempty(d) b(d,:) end end ans = 7 10 ans = 2 5 10

of course of study can store b(d,:) output cell array or whatever future use...

select date.date::date generate_series('2012-01-01'::timestamp time zone,'now'::text::date::timestamp time zone, '1 day') date(date) order date.date desc;

if there no entry date given widget_id, want utilize previous one. widget 1337 doesn't have entry on 2012-05-10, on 2012-05-08, want resultset show 2012-05-08 entry on 2012-05-10 well:

actual data: widget_id | for_date | score 1312 | 2012-05-07 | 20 1337 | 2012-05-07 | 12 1337 | 2012-05-08 | 41 1337 | 2012-05-11 | 500 desired output based on generate series: widget_id | for_date | score 1336 | 2012-05-07 | 20 1337 | 2012-05-07 | 12 1336 | 2012-05-08 | 20 1337 | 2012-05-08 | 41 1336 | 2012-05-09 | 20 1337 | 2012-05-09 | 41 1336 | 2012-05-10 | 20 1337 | 2012-05-10 | 41 1336 | 2012-05-11 | 20 1337 | 2012-05-11 | 500

eventually want boil downwards view have consistent info sets per day can query easily.

i'm working on moving site cf8 cf10 , came across wasn't expecting. mysql query has simple concatenate combine company id company name such:

select concat(co_coid, ' - ',co_company) idconame

on cf8, returns string can display value on cfselect.

998 - company 999 - company b

etc.

however, on cf10 when dump query it's showing binary info , have utilize tostring() on output.

i knew there gotchas required using tostring() when returning encrypted info weren't there before, i'm not sure why it's doing on simple string concatenation.

[update] can changed through connect string or other server wide setting? know can utilize tostring() on output, or cast() in query, server wide ideal. mysql server same server, there's no version alter there.

convert number string,

jquery - Browser local storage get and set json objects issue -

im receiving webservice string has json format. using jquery.parsejson im creating json object on client side (and can access without issues).

after utilize localstorage.setitem add together json object browser local storage. issue comes when localstorage.getitem , [object object] , dont know how access object json object anymore.

do know whats cause , solution this?

thanks

jose.

you can stringify object before storing it, , later parse when retrieve it:

var testobject = { 'one': 1, 'two': 2, 'three': 3 }; // set object storage localstorage.setitem('testobject', json.stringify(testobject)); //retrieve object , parse 1 time again var retrievedobject = json.parse(localstorage.getitem('testobject'));

Android LinearLayout set layout_gravity in java code -

Android LinearLayout set layout_gravity in java code -

i have problem on layout :(

<linearlayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/cuerpo" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_gravity="center_vertical" android:orientation="vertical" > ...

in java code

linearlayout cuerpo = (linearlayout) findviewbyid(r.id.cuerpo); if(align){ cuerpo.setgravity(gravity.center_vertical); }else{ cuerpo.setgravity(gravity.no_gravity); }

i need layout_gravity no gravity.

the layout gravity talking within layoutparams of of linearlayout object. so, logically, have follow next steps:

get layoutparams of linearlayout.

if know layoutparams supposed be, can cast them (beware, based on your choice, must create sure correct!).

set gravity of layoutparams desire.

so in code be:

viewgroup.layoutparams layoutparams = cuerpo.getlayoutparams(); // step 1. linearlayout.layoutparams castlayoutparams = (linearlayout.layoutparams) layoutparams; // step 2. castlayoutparams.gravity = gravity.center_vertical; // step 3.

or simple 1 liner steps in one:

((linearlayout.layoutparams) cuerpo.getlayoutparams()).gravity = gravity.center_vertical;

please beware:

i cannot see trying do, not seem correct. type of layoutparams not type of view, type of layout view reside in.

(i.e. in @gincsait's reference, if have button in linearlayout, layoutparams of button of type linearlayout.layoutparams. same cannot said layoutparams of linearlayout.)

javascript - Is it possible to have event-based communication between browser windows? -

javascript - Is it possible to have event-based communication between browser windows? -

is possible have event-based communication between browser tabs/windows?

i known (at to the lowest degree theoretically) possible using local storage. please provide little illustration of code doing that? send event in 1 tab, , receive in another.

are there libraries/jquery-plugins that?

(i know can communicate between windows/tabs of same browser using cookies; not need; prefer event-based approach, don't want recheck state of cookies every millisecond).

localstorage has events can subscribe syncronize other pages.

note: if update key's value in window a, event not triggered in window a. triggered in windows b & c.

here demo: http://html5demos.com/storage-events

open page in several tabs. alter value on input , see reflected in divs.

here code javascript:

var datainput = document.getelementbyid('data'), output = document.getelementbyid('fromevent'); // handle updates storage-event-test key in other windows addevent(window, 'storage', function (event) { if (event.key == 'storage-event-test') { output.innerhtml = event.newvalue; } }); // update storage-event-test key when value on input changed addevent(datainput, 'keyup', function () { localstorage.setitem('storage-event-test', this.value); });

markup:

<div> <p>your test data: <input type="text" name="data" value="" placeholder="change me" id="data" /> <small>(this echoed on <em>other</em> windows)</small></p> <p id="fromevent">waiting info via <code>storage</code> event...</p> </div>

the html 5 spec discusses info passed in event:

[constructor(domstring type, optional storageeventinit eventinitdict)] interface storageevent : event { readonly attribute domstring key; readonly attribute domstring? oldvalue; readonly attribute domstring? newvalue; readonly attribute domstring url; readonly attribute storage? storagearea; }; dictionary storageeventinit : eventinit { domstring key; domstring? oldvalue; domstring? newvalue; domstring url; storage? storagearea; };

from: http://www.w3.org/tr/webstorage/#the-storage-event

using event, can create other pages react when specific key in local storage updated.

if clone repositories using ssh, solve problem now. but, wanted know if next possible:-

after connecting remote ec2 instance using fabric, if next command hg clone, asks user name , password. have type 2 things manually on command prompt. there way can pass these values run time automatically?

thanks!

you can utilize ssh keys , connect using ssh+hg protocol. it'll auth w/o password if set up.

i using cloud connection easy see usage in centralized location. create collection of log messages, analytic points, errors, etc. in users local storage , fire off asynchronous service @ application launch (and perhaps every few min thereafter) made sure user connected internet, , force records local storage azure mobile service. if haven't set azure mobile services before, they're super easy, cheap, , handy. can create table store info points , add together property user's receipt id (that uniquely identifies them , machine). you've got 1 table usage info of users. that's $0.02.

c# - How do I write a method that can take either a DataGridView or a ListView as input? -

i using next 2 methods persist column info datagridview , listview.

i notice methods similar , in fact utilize same info construction store column settings in. properties storing each column things like, visible, width, displayindex

how can re-write have single function can handle datagridview or listview?

i have thought investigating whether both datagridview , listview inherit mutual class or implement mutual interface - not sure how find out.

also have thought extending each class implement mutual interface... not sure how proceed.

public void savedatagridview ( datagridview view) { foreach (datagridviewcolumn col in view.columns) { // save properties } } public void savedatalistview(listview view) { foreach (columnheader col in view.columns) { // save properties } }

no way until utilize dynamic keyword not increment performance.

datagridview.columns , listview.columns have no mutual base of operations type (except ilist, seek uncertainty luck). neither columnheader , datagridviewcolumn have too.

just short quick question. how index look cobol array? example, if index k=1, next find element of k=2

element(k+1)

unfortunately not acceptable in cobol , know if there alternative?

i'm not sure why think won't work, long set in cobol statement.

id division. program-id. submod. info division. working-storage section. 01 a-nicely-named-table. 05 filler occurs 2 times. 10 a-nicely-named-entry pic x. 01 another-piece-of-data pic x value space. 01 a-nicely-named-subscript binary pic 9(4). linkage section. 01 l-input pic x(4). 01 l-to-hex pic bxbxbxbx. procedure partition using l-input l-to-hex. move "a" a-nicely-named-entry ( 1 ) move "b" a-nicely-named-entry ( 2 ) move 1 a-nicely-named-subscript if a-nicely-named-entry ( a-nicely-named-subscript + 1 ) equal "b" move a-nicely-named-entry ( a-nicely-named-subscript + 1 ) another-piece-of-data end-if display ">" another-piece-of-data "<" goback .

output is:

>b<

with reference comment, not "strictness" thing means. "+ 1" 1 thing, "relative subscript", , "+1" else, sec subscript.

depending on compiler, may able code:

move element(k++1) ...

you may have set moaning compiler, , suppose in may not work. would, however, horrible way write cobol.

i'd suggest not using names element. @ point in future appear "reserved word" cobol. don't shorthand. utilize names, utilize effective spacings. it'll help understand programme little later, , help else has @ it.

php - Codeigniter: getting a user name with id -

i've got project i'm working on in, user can register , assigned id. user has ability post blogs or comment, these blogs or comments assigned authorid same users userid.

i need way name posted below these blogs or messages instead of id-which does.

my blog controller handles blog posting (commenting similar) exception of add together blog function:

function blogtoevoegen() { $this->form_validation->set_rules('blogtitel', 'blogtitel', 'min_length[3]|required|xss_clean|callback_username_check'); $this->form_validation->set_rules('blogtekst', 'blogtekst', 'min_length[2]|required|xss_clean'); if ($this->form_validation->run() == false) { $this->load->view('view_page', $this->view_data); } else { $data = array( 'id' => $this->input->post('id'), 'blogtitel' => $this->input->post('blogtitel'), 'blogtekst' => $this->input->post('blogtekst'), 'auteur_id' => $this->session->userdata('gebruiker_id'), ); $this->db->set('datum', 'now()', false); $this->db->insert('blogs', $data); redirect('blog/eigenblogs'); } }

a function handles displaying of blog post (it gets comments linked blog)

function comments() { $this->db->where('id', $this->uri->segment(3)); $this->db->select('blogtitel, blogtekst, auteur_id, datum'); $data['query2'] = $this->db->get('blogs'); $this->db->where('boodschap_id', $this->uri->segment(3)); $data['query'] = $this->db->get('comments'); $data ["titel"] = "pxl - comment"; $data ["pagina"] = "content_comment"; $this->load->view("view_page", $data); }

the view code displays these blogs (left code comments out)

<?php foreach ($query2->result() $rij): ?> <div class="post"> <h2><?= $rij->blogtitel ?></h2> <p><?= $rij->blogtekst ?></p> <p class="meta">posted <a href="#"><?= $rij->auteur_id ?></a> on <?= $rij->datum ?> </p> </div> <?php endforeach; ?> <hr>

i need way alter auteur_id name (made out of combination first + lastly name).

what need here called sql join. find more in ci manual:

here illustration of need:

$this->db->select('*'); $this->db->from('blogs'); $this->db->join('users', 'users.id = blogs.author_id'); $query = $this->db->get();

this blog posts , query user in users table based on author_id.

entity framework - WPF MVVM Light DataGrid and separate Add Item View -

entity framework - WPF MVVM Light DataGrid and separate Add Item View -

i learning wpf , mvvm , trying create programme has datagrid , button opens form using command can add together item datagrid.

the problem not sure how should implement viewmodels. have 1 viewmodel datagrid form works correctly , using repository retrieve info entity framework.

is possible add together object add together form , have appear in datagrid in other form automatically when press add together button or need refresh action on datagrid? using observable collections in viewmodel , have implemented onpropertychange functionality in collection parameter in view model.

as far can understand when set in repository, every view model gets info should refreshed... though not sure if should write message code work.

i pretty confused , hope can shed lite here... in advance. tell me if have missed mention , add together it:)

edit: how register models:

simpleioc.default.register<parentslistviewmodel>(); simpleioc.default.register<editparentviewmodel>();

and how register repository:

simpleioc.default.register<iparentsrepository, parentsrepository>();

and how retrieve instances of viewmodels:

parentslistviewmodel parentslistviewmodelinstance = servicelocator.current.getinstance<parentslistviewmodel>(); editparentviewmodel editparentviewmodelinstance = servicelocator.current.getinstance<editparentviewmodel>();

the parentslistviewmodel datagrid viewmodel , editparentviewmodel 1 utilize adding/editing records in repository. service locator passes instances of repositories automaticaly have no thought how passes instance of repository viewmodels. pass same instance?

the view models wont automatically refresh when add together repository.

all observable collection inform ui when new item added / removed observable collection (roughly speaking). inotifypropertychange inform ui specific property has changed.

you have few options getting want work (if understand correctly):

you refresh entire observable collection when item added you repository inform datagrid view model event when new item added - datagrid view model can update observable collection you add together form view model talk info grid view model , tell when new item added - in situation you'll need mechanism marshaling info 1 view model another.

does help?

edit 12/02/2013 17:30 gmt:

here's quick , dirty illustration of alternative 2 like. requires same instance of repository shared between 2 view models - in case have injected on constructors.

public interface iparentsrepository{ event eventhandler<myitemaddedeventargs> itemadded; //your normal interface implementation here } public class parentsrepository : iparentsrepository { public event eventhandler<myitemaddedeventargs> itemadded; public list<myitem> getallitems() { //logic returns items here homecoming new list<myitem>(); } public void additem(myitem item) { //logic adds item here //fire item added event onitemadded(item); } private void onitemadded(myitem item) { if(itemadded != null) itemadded(this, new myitemaddedeventargs(item)); } } public class myitemaddedeventargs : eventargs { public myitemaddedeventargs(myitem itemadded) { } public myitem itemadded { get; set; } } public class myitem { public string someproperty { get; set; } } public class mydatagridviewmodel { private readonly iparentsrepository _parentsrepository; public mydatagridviewmodel(iparentsrepository parentsrepository) { _parentsrepository = parentsrepository; _parentsrepository.itemadded += _parentsrepository_itemadded; var myitems = _parentsrepository.getallitems(); myitems = new observablecollection<myitem>(myitems); } void _parentsrepository_itemadded(object sender, myitemaddedeventargs e) { if(!myitems.contains(e.itemadded)) myitems.add(e.itemadded); } public observablecollection<myitem> myitems { get; set; } } public class myadditemviewmodel { private readonly iparentsrepository _parentsrepository; public myadditemviewmodel(iparentsrepository parentsrepository) { _parentsrepository = parentsrepository; } //your logic add together item here }

this method adjusted method 1, when _parentsrepository_itemadded event fires, rather adding new item, fetch whole dataset again.

android - ImageButton with different states images size -

android - ImageButton with different states images size -

how can prevent imagebutton having fixed size? drawables used in selector have different size, , want imagebutton resize match image size.

i've tried adjustviewbounds without success.

<relativelayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:padding="8dp" > <imagebutton android:id="@+id/picture_imagebutton" android:layout_width="wrap_content" android:layout_height="wrap_content" android:adjustviewbounds="true" android:src="@drawable/tab_background_selector" /> </relativelayout>

instead of using imagebutton, utilize imageview because imagebutton cannot resized based on imagesize. imageview best alternative way can suggest problem. acheive next way:

layout.xml:

<relativelayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <imageview android:id="@+id/image" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/image_selection"/> </relativelayout>

image_selection.xml:

<selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_focused="true" android:state_pressed="true" android:drawable="@drawable/default_image"/> //default_image.png displayed when activity loads. <item android:state_focused="false" android:state_pressed="true" android:drawable="@drawable/default_image_hover" /> //default_image_hover.png image displaed during onclick of imageview <item android:state_focused="true" android:drawable="@drawable/default_image_hover" /> <item android:state_focused="false" android:drawable="@drawable/default_image"/> </selector>

i'm next tutorial here http://trek.github.com/ , i'm @ blocked point.

ember code in index.html:

<script type="text/x-handlebars" data-template-name="application"> <h2>ember committers:</h2> {{outlet}} </script> <script type="text/x-handlebars" data-template-name="contributors"> {{#each person in controller}} {{person.login}} {{/each}} </script>

ember code in app.js:

app = ember.application.create(); // application default controller , view app. applicationcontroller = ember.controller.extend(); app.applicationview= ember.view.extend( { templatename: 'application' }); // contributors controller , view... app. allcontributorscontroller = ember.arraycontroller.extend(); app.allcontributorsview= ember.view.extend( { templatename: 'contributors' }); app.router = ember.router.extend({ root: ember.route.extend({ index: ember.route.extend({ route: '/', connectoutlets: function(router) { // here connect allcontributers info & template outlet in application template. router.get('applicationcontroller').connectoutlet('allcontributors', [{login:'wycats'},{login: 'tomdale'}]); } }) }) });

at point when run it, expect see text "ember committers:" along 2 login names specified via connectoutlet().

i see header text , not logins , don't errors.

any ideas?

i've had success when i've done routes way on emberjs.com guide page http://emberjs.com/guides/routing/defining-your-routes/

you'd define routes via

app.router.map(function(){ this.route('contributors'); });

at point, default if go #/contributors set contributors template {{outlet}} (no view declaration necessary).

if need alter outlet, within route (not router! confusion cost me day) creating 1 contributors:

app.contributorsroute = ember.route.extend({ connectoutlets: ... });

how to programmatically add colspan in ZK/Zul? -

how to programmatically add colspan in ZK/Zul? -

how set property of colspan in zul framework?

e.g.

tr tr = new tr(); td td = new td(); tr.appendchild(td); td = new td(); tr.appendchild(td);

now, in next row, have set single td within table row through composer cover space of 2 td . how can accomplish this?

<table> <tr> <td> </td/> <td> </td> </tr> <tr> <td colspan="2"> </td> </tr> </table>

in zul not done <table>, <tr>, , <td> tags <grid>, <row>, , <cell> tags. so..

<grid> <columns> <column label="a" /> <column label="b" /> </columns> <rows> <row> <cell> <label value="item 1" /> </cell> <cell> <label value="item 2" /> </cell> </row> <row> <cell colspan="2"> <label value="item 3" /> </cell> </row> </rows> </grid>

from java side, then, becomes easy..

grid grid = new grid(); rows rows = new rows(); rows.setparent(grid); row row1 = new row(); row1.setparent(rows); cell cell1 = new cell(); cell1.setparent(row1); cell1.appendchild(new label("item1")); cell cell2 = new cell(); cell2.setparent(row1); cell2.appendchild(new label("item2")); row row2 = new row(); row2.setparent(rows); cell cell3 = new cell(); cell3.setparent(row2); cell3.appendchild(new label("item3")); cell3.setcolspan(2); // you're looking

knockout.js - javascript - knockout - how it works? -

knockout.js - javascript - knockout - how it works? -

i trying utilize knockout , wonder myself how works network point of view : can see "calls" browser client server retrieve data? mean : used utilize ajax calls populate forms, tables... => can see ajax calls server. same thing when need submit form : can see ajax calls. means can debug firefbug , see parameters sent/ response received, inluding headers (request/response). knocknout, info in form "binding" automatically framework ko. so, know how works really? how calls done? there way "see" info flow?

from network point of view, nil changes when using knockout. you'll still need create ajax calls populate view models, they're outside framework, not part of it. means can still set breakpoint on ajax calls , observe stuff beingness sent , received.

a major code departure network calls exist within knockout viewmodel.

var somevm = function(data) { var self = this; self.id = ko.observable(data.id); // ... self.getitems = function() { // ajax phone call here, method on vm } }

however, tj crowder points out - key mechanic of knockout binding client side view model user interface, either info population or visibility command in single page application. networking you'll have handle, it's not part of knockout. likely, you'll create little changes in placement of ajax calls.

objective c - Zooming UIImage in a UIScrollView -

i have custom class implements uiscrollview.

i created 1 uiimageview , add together subview of uiscrollview. scrolls vertically , horizontally perfectly, seems ignoring zooming stuff. here code:

- (void) setupboard { // add together board uiimageview *imageholder = [[uiimageview alloc] initwithimage:[uiimage imagenamed:@"grid.jpg"]]; [self addsubview:imageholder]; self.contentsize = cgsizemake(imageholder.frame.size.width, imageholder.frame.size.height); self.indicatorstyle = uiscrollviewindicatorstylewhite; self.maximumzoomscale = 5.0; self.minimumzoomscale = 0.2; self.zoomscale = 0.7; self.clipstobounds = yes; }

how zoom using standard pinch gestures? help appreciated. thanks!

from uiscrollview class reference overview:

the uiscrollview class can have delegate must adopt uiscrollviewdelegate protocol. zooming , panning work, delegate must implement both viewforzoominginscrollview: , scrollviewdidendzooming:withview:atscale:; in addition, maximum (maximumzoomscale) , minimum (minimumzoomscale) zoom scale must different.

i suspect either haven't assigned delegate scroll view, or delegate doesn't implement both of methods.

jquery - Make an async ajax request when clicking on a link -

jquery - Make an async ajax request when clicking on a link -

i'm using php/jquery , have next scenario:

i have site (site1.php) link, points site (site2.php), added link ajax-onclick-event jquery requests site (ajaxcall.php). other site has "a lot of work" do, it's not short request.

my goal is: set request ajaxcall.php in background (asynchron) , go site2.php. (i not need reply of ajaxcall.php)

my first implementation this:

<!doctype html> <html> <head> <script src="http://code.jquery.com/jquery-1.9.1.min.js"></script> <script type="text/javascript"> $(document).ready(function() { $("#link").on("click",function(){ $.get('./ajaxcall.php'); </script> </head> <body> <a href="./file2.php" id="link">link</a> </body> </html>

obviously won't work. because ajax-request (which async), aborted page changed.

so far can see have 2 possiblities here:

make request synchron & show loading indicator ($.ajax({url: './ajaxcall.php',async:false});) --> disadvantage: file2.php not open before ajaxcall.php done.

open popup (window.open('ajaxcall.php')) , create synchron-ajax-request / or similar there , auto-close after --> advantage: file2.php should open --> (big)disadvantage: popup

??? improve way ???

i hope understood i'm trying accomplish , can help me :)

try code...

$(document).ready(function() { $("#link").on("click",function(e){ e.preventdefault(); var href = this.href; $.get('./ajaxcall.php', function() { window.location.href = href; }); }); });

it stops execution of link (with e.preventdefault()), gets target url , redirects page location when request complete.

hello oh mighty stackoverflow.com community.

this question i've been fiddling while now. have (will have) arduino 2560 talking rpi using pair of 388 rf transmitter/receiver - serial communication. create matters worse, there many transmitters (arduinos) , single reciever (rpi). 2 questions cannot quite figure reply for:

protocol extremely primitive - if want error correction, have take myself. thought utilize extremely simple parity bit start , see how goes. thoughts?

speaking of protocol - how going encode data? there single number going transmit - transmitter id - accompanied boolean flag (sensor active/inactive). best way encode info serial rf transmission? text? can transmit stream of bytes, much be, create farther porting hard (big/little endian, word size, etc). tried consider exotics such nanopb no matter how protocol buffers great overkill task. understand position wobbly here, i'd appreciate ideas.

finally, know sounds lame i'm pretty sure has done before , there might sort of cross-platform library can utilize exchange. if indeed so, great - can want instead of re-inventing wheel.

anyway, here's stand. appreciate answers.

this transmitter i'm using , receiver.

thanks lot everyone!

have looked @ arduino virtual wire library – http://www.pjrc.com/teensy/td_libs_virtualwire.html. works fine transmitters , receivers on arduino , should not hard port raspberry pi. there forum give-and-take @ http://www.raspberrypi.org/phpbb3/viewtopic.php?t=24215&p=239410.

what best way execute piece of code after arbitrary amount of time on app engine?

i figured using countdown millis or etamillis taskqueue work, haven't seen evidence of doing same thing, such long time frames.

is best approach, or there improve way?

if able persist object in datastore of relevant info future processing (including when processing object's info should begin), have cron job periodically query datastore date/time range filter , trigger processing of above objects @ appropriate time.

what want

currently have png image of 4000x4000. after using tinypng.org became 288kb file.

now want fastes way load image, place in dom , able draw lot of canvas' on it.

i tested , results stunned me.

what tested

i made 3 tests , check load speed.

(423ms) <canvas> (138ms) <img> (501ms) css background-image

the <img> tag fastest.

question

so, bad-practice utilize <img> tag display huge (background) image , utilize dirty css able draw canvas on it?

or improve utilize canvas in case , don't worry longer load time?

great question! related: when utilize img vs. css background-image?

from article, if people intended print page wouldn't utilize <img> - appear on print. same apply <canvas>, making background-image logical solution.

how background image added through css? inline or through own stylesheet? if it's using own stylesheet, have tried compressing css before testing speed?

this related, suppose: do images load faster in html or css?

well, depends if build facebook sdk only, or you've included library own android project (i suppose that's case). if have jar's within project folder (added jars project), remove them , re-create them somewhere outside project root, add together them 1 time again external jars. question might possible duplicate.

my question: there way command line width more exactly avoid result in sec plot? particularly find document-unfriendly, , more publishing purposes include plot newly defined line width.

best, ismail

whilst @didzis has correct answer, expand on few points

aesthetics can set or mapped within ggplot call.

an aesthetic defined within aes(...) mapped data, , legend created.

an aesthetic may set single value, defining outside aes().

as far can tell, want set size single value, not map within phone call aes()

when phone call aes(size = 2) creates variable called `2` , uses create size, mapping constant value within phone call aes (thus appears in legend).

using size = 1 (and without reg_labeller perhaps defined somewhere in script)

figure29 + geom_line(aes(group=factor(tradlib)),size=1) + facet_grid(regionsfull~., scales="free_y") + scale_colour_brewer(type = "div") + theme(axis.text.x = element_text(colour = 'black', angle = 90, size = 13, hjust = 0.5, vjust = 0.5),axis.title.x=element_blank()) + ylab("fsi (%change)") + theme(axis.text.y = element_text(colour = 'black', size = 12), axis.title.y = element_text(size = 12, hjust = 0.5, vjust = 0.2)) + theme(strip.text.y = element_text(size = 11, hjust = 0.5, vjust = 0.5, face = 'bold'))

and size = 2

figure29 + geom_line(aes(group=factor(tradlib)),size=2) + facet_grid(regionsfull~., scales="free_y") + scale_colour_brewer(type = "div") + theme(axis.text.x = element_text(colour = 'black', angle = 90, size = 13, hjust = 0.5, vjust = 0.5),axis.title.x=element_blank()) + ylab("fsi (%change)") + theme(axis.text.y = element_text(colour = 'black', size = 12), axis.title.y = element_text(size = 12, hjust = 0.5, vjust = 0.2)) + theme(strip.text.y = element_text(size = 11, hjust = 0.5, vjust = 0.5, face = 'bold'))

you can define size work appropriately final image size , device type.

the issue having value @ bottom, requiredoptions. want text box enabled only if withprotocol checkbox checked. however, can't figure out value , type of value use. have tried following:

html5 - How do i use KineticJS polygon object with geoJSON coordinates rather than points? -

html5 - How do i use KineticJS polygon object with geoJSON coordinates rather than points? -

i creating interactive map on html5 canvas using kineticjs, problem map info in geojson, have polygon coordinates rather polygon points.

this how polygon points(according tutorial)

//javascript object map info var mymap = { 'russia': { points: [44,1,397,1,518,2,518,151,515,..............6,43,4,43,4] }, 'azerbaijan': { points: [198, 242, 201, 245, 203,..............197, 242] }, 'uae': { points: [224,406,225,410,...............225,407] } }; //function homecoming map info function getdata() { homecoming mymap; }

then utilize kineticjs polygon object draw map on html5 canvas.

//store map info in variable var areas = getdata(); //loop through map (var key in areas) { (function () { var k = key; var area = areas[key]; var points = area.points; var shape = new kinetic.polygon({ points: points, fill: '#fff', stroke: '#555', strokewidth: .5, alpha: 0.1 }); } ()); }

does know how can accomplish same geojson coordinates? here sample of geojson. coordinates nested within geometry object.

{ "type": "featurecollection", "features": [{ "type": "feature", "id": 0, "properties": { "objectid_1": 29, "objectid": 29, "county_nam": "baringo", "county_cod": 30, "shape_leng": 5.81571392065, "shape_area": 0.88451236881 }, "geometry": { "type": "polygon", "coordinates": [ [ [ 36.028686523000033, 1.276123047000056 ], [ 36.036499023000033, 1.263916016000053 ], [ 36.039306641000053, 1.259887695000032 ],............[ 36.028686523000033, 1.276123047000056 ] ] ] } } ] }

var myarray = new array(); for( var level1 in coordinates ){ // each array in coordinates for( var level2 in level1){ // each array in array for( var number in level2){ // each number in array myarray.push(number); } } } var points = myarray;

maybe many levels of nesting, main idea:

go through sub arrays , grab numbers in each , place them in new array.

how find element <a> in page contain href attr /dailytickets/front/user.form.php, alter /dailytickets/front/contacts.form.php?

notice want maintain url query parameters (id) next path (user.form.php). example, changing this:

<a id="user_648_648" href="/dailytickets/front/user.form.php?id=648">conseilleruser</a>

to this:

<a id="user_648_648"href="/dailytickets/front/contacts.form.php?id=648">conseilleruser</a>

i'm starting this, don't know how end it:

$('a[href*="dailytickets/front/user.form.php"]').each(function () { if ($(this).children().length == 0) { ........... } });

there's no need loop, jquery interally you, , using selector outright alter , elements match:

$('a[href*="dailytickets/front/user.form.php"]').attr('href', function(i,href) { homecoming href.replace('user.form.php', 'contacts.form.php'); });

c# - Do a post since a JQUERY dialog? -

i've got 2 buttons within of htmlform , working well, differenciate of pass name of button in actionname. below:

[httppost] public actionresult index(string button, quizcompletedviewmodel q) { // quizcompletedviewmodel model of razor view ... } @using (html.beginform("index", "quiz", formmethod.post, new { id = "form" })) { <div> <!-- old code using 2 buttons post --> <div class="float-right"> @* <input name="button" type="submit" value="save" /> <input name="button" type="submit" value="done" />*@ <input name="button" type="button" value="done" /> </div> <div id="dialog-form"> <input name="button" type="button" value="cancel" /> <input name="button" type="submit" value="save" /> <input name="button" type="submit" value="done" /> </div> </div> <div id="question-container"> @for (int = 0; < model.questions.count; i++) { ... } </div> }

then need alter 2 buttons of current view , show pop these 2 buttons above (id="dialog-form"). momment little hard me using jquery when user press buttons , perform post old code.

can lend me hand?

i think might help you, have tweak needs, jquery dialog displays go on button in code illustration , bind function it, can replace asp.net webforms __dopostback cause postback on mvc page.

$("#dialog").dialog({ autoopen: false, height: 380, width: 650, modal: true, close: function () { $('#btncreateaccount').button('refresh'); }, buttons: { 'continue': function () { $(this).dialog('close'); __dopostback($("#<%=btncreateaccount.clientid %>").attr("name"), ''); } } });

entity framework - .NET EF - dividing a byte field results an int instead of double -

entity framework - .NET EF - dividing a byte field results an int instead of double -

interesting one.

see next entity framework query:

entities.select(x => new { x.experiencemonths, calculated = (x.experiencemonths > 0 ? x.experiencemonths / 12 : 0) })

the column experiencemonths tinyint in database, means it's byte in ef model.

i'd expect calculated column double (float), since we're dividing number, no matter ends int , decimal portion of result removed, ex 3.7 ends 3.

is there way forcefulness ef convert result somehow double? adding (double) cast before partition look breaks @ runtime.

using ef5.

thanks!

i tried:

calculated = (x.experiencemonths > 0 ? ((double)x.experiencemonths) / 12 : 0)

and worked fine

r - pdf font and graph formatting (win.graph) -

r - pdf font and graph formatting (win.graph) -

i came upon problem in r in combination have tried solve , searched in internet, not solve yet. hope can help me.

i run r(x64) on windows 7. graphic device automatically uses arial font, , when save graphs bitmap "font" naturally remains is. however, prefer saving graphs pdf, in case font in resulting pdf exchanged helvetica when save via gui save button.

i found solution in internet, using arial afm-files , pdf("test_auto.pdf", family = "arial"), resulted in pdf using arial font---so far good.

now have to/want alter graph layout using win.graph, , problems start. here example:

arial <- type1font(family = "arial", metrics = c("c:/r_fonts/arialplain.afm", "c:/r_fonts/arialbold.afm", "c:/r_fonts/arialitalic.afm", "c:/r_fonts/arialbolditalic.afm")) pdffonts(arial = arial) setwd("c:/pdfcrop") d1<-matrix(c(1,2,3,4,6,3),3,2) d2<-matrix(c(1,2,3,5,3,1),3,2) #pdf("test_auto.pdf", family = "arial") win.graph(8.3,12,12) layout(matrix(c(1,2),1,2,byrow=true)) plot(d1,type="l",main="gobble r") plot(d2,type="l",main="gobble r") #dev.off()

now code works create graph looks want look, have save graph manually (file->save as) , helvetica font in pdf.

alternatively can alter lower part in

pdf("test_auto.pdf", family = "arial") #win.graph(8.3,12,12) layout(matrix(c(1,2),1,2,byrow=true)) plot(d1,type="l",main="gobble r") plot(d2,type="l",main="gobble r") dev.off()

and produces pdf-file uses arial, graph has other dimensions intending. when using both pdf "cannot opened because does't contain pages" (though not 0kb in size).

is there way work, or alternative win.graph can utilize between pdf() , dev.off()?

thanks help.

oh god, i'm sorry, stupid!

during overlooked, pdf-device has own size parameters.

arial <- type1font(family = "arial", metrics = c("c:/r_fonts/arialplain.afm", "c:/r_fonts/arialbold.afm", "c:/r_fonts/arialitalic.afm", "c:/r_fonts/arialbolditalic.afm")) pdffonts(arial = arial) setwd("c:/pdfcrop") d1<-matrix(c(1,2,3,4,6,3),3,2) d2<-matrix(c(1,2,3,5,3,1),3,2) pdf("test_auto.pdf", width=8.3, height=12, family = "arial") #win.graph(8.3,12,12) layout(matrix(c(1,2),1,2,byrow=true)) plot(d1,type="l",main="gobble r") plot(d2,type="l",main="gobble r") dev.off()

Why am I seeing ZgotmplZ in my Go HTML template output? -

Why am I seeing ZgotmplZ in my Go HTML template output? -

when i'm calling go template function output html, displays zgotmplz.

sample code:

http://play.golang.org/p/tfuja_pfkm

package main import ( "html/template" "os" ) func main() { funcmap := template.funcmap{ "printselected": func(s string) string { if s == "test" { homecoming `selected="selected"` } homecoming "" }, "safe": func(s string) template.html { homecoming template.html(s) }, } template.must(template.new("template").funcs(funcmap).parse(` <option {{ printselected "test" }} {{ printselected "test" | safe }} >test</option> `)).execute(os.stdout, nil) }

output:

<option zgotmplz zgotmplz >test</option>

"zgotmplz" special value indicates unsafe content reached css or url context @ runtime. output of illustration be

<img src="#zgotmplz">

you can add together safe , attr function template funcmap:

package main

import ( "html/template" "os" ) func main() { funcmap := template.funcmap{ "attr":func(s string) template.htmlattr{ homecoming template.htmlattr(s) }, "safe": func(s string) template.html { homecoming template.html(s) }, } template.must(template.new("template").funcs(funcmap).parse(` <option {{ .attr |attr }} >test</option> {{.html|safe}} `)).execute(os.stdout, map[string]string{"attr":`selected="selected"`,"html":`<option selected="selected">option</option>`})

}

the output looks like:

<option selected="selected" >test</option> <option selected="selected">option</option>

you may want define other functions can convert string template.css,template.js,template.jsstr,template.url etc.
