javascript - Can I get text source of link stylesheet? -

i seek css text link element. illustration style element simplest:

[].map.call(document.stylesheets, function(stylesheet) { var tag = stylesheet.ownernode.tagname.tolowercase(); if (tag == 'style') { homecoming stylesheet.ownernode.textcontent; } else if (tag == 'link') { //is possible receive source here without ajax? } });

is there way link source without loading text?

with document.stylesheets can interate through loaded stylesheets on page. each 1 list of css rules elements. can obtain csstext property of these css rules.

based on this post, i've come sample script css rules text loaded on page. hope helps...

http://jsfiddle.net/qmaw7/1/

var cssstyles = ""; //started @ index 1 index 0 browser's user agent stylesheet. for(var i=1; i<document.stylesheets.length; i++) { var style = null; (document.stylesheets[i]) { if (typeof cssrules != "undefined") style = cssrules; else if (typeof rules != "undefined") style = rules; } for(var item in style) { if(style[item].csstext != undefined) cssstyles = (style[item].csstext); } } alert(cssstyles);

Read many Excel files from R -

Read many Excel files from R -

it's first time r, maybe problem trivial

i need download date xls files url , each 1 should in 1 info frame. here .

i decided utilize gdata bundle (package ‘xlsreadwrite’ not available r version 3.1.0, rodbc not available win64)

downloading works great 1 file (year e.g = 2013 )

readxls<-function() { library("gdata") link<-paste0("http://nbp.pl/kursy/archiwum/archiwum_tab_a_",year,".xls") xlsdata <<- read.xls(link, sheet = 1, perl = "c:\\perl64\\bin\\perl.exe", header=true) }

i tried read many .xls list() using loop. (e.g. y_begin=2012, y_end=2014)

readxls<-function() { library("gdata") ldata<<- list() j=1 (i in y_begin:y_end) { link<-paste0("http://nbp.pl/kursy/archiwum/archiwum_tab_a_",i,".xls") xlsdata <<- read.xls(link, sheet = 1, perl = "c:\\perl64\\bin\\perl.exe", header=true) ldata[j] <<- xlsdata j<-j+1 } }

i thought after i'd able merge them, don't know how info single info frame in list illustration > view(ldata[2]) returns first collumn

avoid utilize for loop , specially side effect. improve utilize lapply here. r way things ( functional programming). here this:

library(gdata) readxls<-function() { ids <- seq(y_begin,y_end) links <-paste0("http://nbp.pl/kursy/archiwum/archiwum_tab_a_",ids,".xls") lapply (links,function(i) read.xls(link, sheet = 1, perl = "c:\\perl64\\bin\\perl.exe", header=true) ) }

this homecoming list of data.frame, merge them, assuming ll same:

ll <- readxls() do.call(rbind,ll)

r excel

c++ - Is VC++ still broken Sequentially-Consistent-wise? -

c++ - Is VC++ still broken Sequentially-Consistent-wise? -

i watched (most of) herb sutter's atmoic<> weapons video, , wanted test "conditional lock" loop within sample. apparently, although (if understand correctly) c++11 standard says below illustration should work , sequentially consistent, not.

before read on, question is: correct? compiler broken? code broken - have race status here missed? how bypass this?

i tried on 3 different versions of visual c++: vc10 professional, vc11 professional , vc12 express (== visual studio 2013 desktop express).

below code used visual studio 2013. other versions used boost instead of std, thought same.

#include <iostream> #include <thread> #include <mutex> int = 0; std::mutex m; void other() { std::lock_guard<std::mutex> l(m); std::this_thread::sleep_for(std::chrono::milliseconds(2)); = 999999; std::this_thread::sleep_for(std::chrono::seconds(2)); std::cout << << "\n"; } int main(int argc, char* argv[]) { bool work = (argc > 1); if (work) { m.lock(); } std::thread th(other); (int = 0; < 100000000; ++i) { if (i % 7 == 3) { if (work) { ++a; } } } if (work) { std::cout << << "\n"; m.unlock(); } th.join(); }

to summarize thought of code: global variable a protected global mutex m. assuming there no command line arguments (argc==1) thread runs other() 1 supposed access global variable a.

the right output of programme print 999999.

however, because of compiler loop optimization (using register in-loop increments , @ end of loop copying value a), a modified assembly though it's not supposed to.

this happened in 3 vc versions, although in code illustration in vc12 had plant calls sleep() create break.

here's of assembly code (the adress of a in run 0x00f65498):

loop initialization - value a copied edi

27: (int = 0; < 100000000; ++i) 00f61543 xor esi,esi 00f61545 mov edi,dword ptr ds:[0f65498h] 00f6154b jmp main+0c0h (0f61550h) 00f6154d lea ecx,[ecx] 28: { 29: if (i % 7 == 3)

increment within condition, , after loop copied location of a unconditionally

30: { 31: if (work) 00f61572 mov al,byte ptr [esp+1bh] 00f61576 jne main+0edh (0f6157dh) 00f61578 test al,al 00f6157a je main+0edh (0f6157dh) 32: { 33: ++a; 00f6157c inc edi 27: (int = 0; < 100000000; ++i) 00f6157d inc esi 00f6157e cmp esi,5f5e100h 00f61584 jl main+0c0h (0f61550h) 32: { 33: ++a; 00f61586 mov dword ptr ds:[0f65498h],edi 34: }

and output of programme 0.

the 'volatile' keyword prevent kind of optimization. that's it's for: every utilize of 'a' read or written shown, , won't moved in different order other volatile variables.

the implementation of mutex should include compiler-specific instructions cause "fence" @ point, telling optimizer not reorder instructions across boundary. since implementation not compiler vendor, maybe that's left out? i've never checked.

since 'a' global, think compiler more careful it. but, vs10 doesn't know threads won't consider other threads utilize it. since optimizer grasps entire loop execution, knows functions called within loop won't touch 'a' , that's plenty it.

i'm not sure new standard says thread visibility of global variables other volatile. is, there rule prevent optimization (even though function can grasped way downwards knows other functions don't utilize global, must assume other threads can) ?

i suggest trying newer compiler compiler-provided std::mutex, , checking c++ standard , current drafts that. think above should help know for.

how do I change the location of the httpd.conf for Apache on windows? -

i working on setting load balancing cluster on windows server 2012 , have shared drive want configuration files apache exist at. way each fellow member of lb can load exact same config files. how alter config file located independently of serverroot is?

start apache process -d parameter , give alternative serverroot argument, though i'd imagine much improve thought utilize mechanism sync files locally each server.

also read http://httpd.apache.org/docs/2.4/mod/core.html#mutex, it's advised if you're running networked file system.

if want specify main config file, start process -f parameter , path config file argument.

inserting variables and looping over a python class call -

i'm using flask-sqlalchemy , flask-wtf. want take string produced "row.form_field" query , place wtf form class call. ideas on how can pull off?

from forms import form_list models import form_value form = form_list values = form_value.query.filter_by(form_entry_id = id) row in values: print row.form_field, row.value #this works. form.row.form_field.data = row.value #this not! # form.???how insert "row.form_field" here???.data = row.value

you can utilize getattr:

getattr(form, row.form_field).data = row.value

but easier, can pass info instantiated wtforms class:

data = {row.form_field: row.value row in values} form_list = formlist(**data)

Java - MySQL to Hive Import where MySQL Running on Windows and Hive Running on Cent OS (Horton Sandbox) -

before reply , comments. tried several alternative found in stackoverflow end failure. next links -

how can execute sqoop in java? how utilize sqoop in java program? how import table mysql hive using java? how load sql info hortonworks sandbox?

i tried in horton sandbox through command line , succeded.

sqoop import --connect jdbc:mysql://192.168.56.101:3316/database_name --username=user --password=pwd --table table_name --hive-import -m 1 -- --schema default

where 192.168.56.101 windows , 192.168.56.102 horton sandbox 2.6.

now want same thing java java code run somewhere else not in horton sandbox.

how loacate hive_home , other sqoop parameters because running in sandbox. parameters have pass. should passes sqoopoptions or sqoop.runtools string array arguments. both failing. i confused while import library (com.cloudera.sqoop , org.apache.sqoop) , this

the method run(com.cloudera.sqoop.sqoopoptions) in type importtool not applicable arguments (org.apache.sqoop.sqoopoptions) 2 line (option parameter added between 2 lines)

sqoopoptions options = new sqoopoptions(); int ret = new importtool().run(options);

if take cloudera method deprecated if take apace run method doesn't take options argument

i strucked in weeks. please help.

yes can via ssh. horton sandbox comes ssh back upwards pre installed. can execute sqoop command via ssh client on windows. or if want programaticaly (thats have done in java) have follow step.

download sshxcute java library : https://code.google.com/p/sshxcute/ add build path of java project contains next java code import net.neoremind.sshxcute.core.sshexec; import net.neoremind.sshxcute.core.connbean; import net.neoremind.sshxcute.task.customtask; import net.neoremind.sshxcute.task.impl.execcommand; public class testssh { public static void main(string args[]) throws exception{ // initialize connbean object, parameter list ip, username, password connbean cb = new connbean("192.168.56.102", "root","hadoop"); // set connbean instance parameter sshexec static method getinstance(connbean) retrieve singleton sshexec instance sshexec ssh = sshexec.getinstance(cb); // connect server ssh.connect(); customtask sampletask1 = new execcommand("echo $ssh_client"); // print client ip connected ssh server on horton sandbox system.out.println(ssh.exec(sampletask1)); customtask sampletask2 = new execcommand("sqoop import --connect jdbc:mysql://192.168.56.101:3316/mysql_db_name --username=mysql_user --password=mysql_pwd --table mysql_table_name --hive-import -m 1 -- --schema default"); ssh.exec(sampletask2); ssh.disconnect(); } }

How to get_absolute_url with domain in Django template? -

How to get_absolute_url with domain in Django template? -

so struggling bit, logically seems simple due limited understanding of django not sure , how formulate solution.

basically have blog app set , shows complete(all content including disqus discussion) latest post on home page. post has farther link posts own page well. have set disqus , need key info utilize disqus_url , disqus_identifier. have set model follows method get_absolute_url follows:

def get_absolute_url(self): homecoming reverse('blog.views.renderblog',args=[str(self.id),str(self.slug)])

my view set follows:

def renderblog(request,postid=1,slug=none): template = 'blog_home.html' if(postid == 1 , slug == none): post = post.objects.latest('date_created') else: post = post.objects.get(slug=slug, id=postid) info = { 'post':post, } homecoming render(request, template, data)

as can see view set handle both url's follows:

url(r'^$', 'renderblog', name='bloghome'), url(r'^post/(?p<postid>\d{1,4})/(?p<slug>[\w-]+)/$', 'renderblog', name='blogpostpage'),

in template setting disqus_identifier = '{{ post.get_absolute_url }}' , hardcoding domain portion in meantime disqus_url = 'http://127.0.0.1{{ post.get_absolute_url }}';.. same goes comment count <a href="" data-disqus-identifier.

i dont doing things in hackish manner, best method me total absolute url. have looked @ request.get_absolute_uri not sure on how utilize want.

thanks

the way configure context_processor:

from django.contrib.sites.models import site def base_context_processor(request): homecoming { 'base_url': "http://%s" % site.objects.get_current().domain } # or if don't want utilize 'sites' app homecoming { 'base_url': request.build_absolute_uri("/").rstrip("/") }

in settings.py:

template_context_processors = ( ... 'path.to.base_context_processor', ... )

(in newer versions of django, modify context_processors under templates, options instead.)

then in templates:

<a href="{{ base_url }}{{ obj.get_absolute_url }}">object name</a>

another solution utilize request.build_absolute_uri(location), have create template tag takes request object , location or object has get_absolute_uri method. able utilize templates that: {% get_full_uri request=request obj=post %}. here documentation on how write custom tags.

python - pass multiple dictionaries to a function as an argument -

python - pass multiple dictionaries to a function as an argument -

i have 2 dictionaries: sp=dict{'key1':'value1','key2':'value2'}, cp=dict{'key1':'value1','key2':'value2'}

i have function take 2 dictionaries inputs, don't know how that.

i'd tried:

def test(**sp,**cp): print sp.keys(),cp.keys() test(**sp,**cp)

the real function more complicated lots of modification of 2 dictionaries. simple test function doesn't work me :(

if want take 2 dictionaries separate arguments, do

def test(sp, cp): print sp.keys(),cp.keys() test(sp, cp)

you utilize ** when want pass individual key/value pairs of dictionary separate keyword arguments. if you're passing whole dictionary single argument, pass it, same way other argument value.

javascript - Angular application architecture + controller re-initialising issues -

javascript - Angular application architecture + controller re-initialising issues -

i have been developing angularjs search our website on lastly week , have ran big problem, think maybe misunderstanding of technology case (this first medium sized angularjs app).

basic overview of how app works

user types in search query, api returns data, i utilize ng-repeat on checkbox input field iterate on facets returned, each input field has ng-model (e.g. <input type="checkbox" ng-model="filters['key']['name'] />, property on filters object have (plain old empty js object), when user clicks facet (checks checkbox), property added filters (e.g. { brand: { sony: true } }, a have watch on filters, updates url + performs search.

here issues having

the initial page load blocking ui (the more facets returned api, bigger freeze), it's not noticeable on 100~ items (although there tiny delay!), 1 time bigger that, blocking ui noticeably long time.

the above not issue in itself, happy little delay on initial page load whilst ng-repeat adding stuff dom, when update $location.path, pretty url (after filter clicked), controller getting re-initialised, , huge freeze again.

here why think huge delay: route has changed, hence angular go fetch template again, re-initialise controller , in turn add together items dom again, correct?

i found using $location.search , reloadonsearch set false in route, controller isn't re-initialised, when click in browser, have write code handle both cases, ideally i'd utilize same code both!

i have tried various fixes found in angularjs github issues prevent path changes reloading controller, , briefly tried ui.router, both without success!

my questions

is there uniform way modify $location.path doesn't issue total controller reload, works / forwards buttons in browser? (using $location.search not issue if there isn't, how can ng-repeat not lock page whilst adding hundreds of elements dom? (since in scrollable list, need write custom directive partially render list? + add together more on scroll)

cheers.

answered myself after long search, , doesn't produce elegant solution!

i dropped in ui-router reloadonsearch: false, in states, downside have hear $locationchangesuccess event , lot of manual work populate scope state that's in url.

.net - Performance issue with reading integers from a binary file at specific locations in F# -

this morning asked here why python code (a lot) slower f# version i'm wondering whether f# version can made faster. ideas how create faster version of below code reads sorted list of unique indexes binary file 32-bit integers? note tried 2 approaches, 1 based on binaryreader, other 1 based on memorymappedfile (and more on github).

module simpleread allow readvalue (reader:binaryreader) cellindex = // set stream right location reader.basestream.position <- cellindex*4l match reader.readint32() | int32.minvalue -> none | v -> some(v) allow readvalues filename indices = utilize reader = new binaryreader(file.open(filename, filemode.open, fileaccess.read, fileshare.read)) // utilize list or array forcefulness creation of values (otherwise reader gets disposed before values read) allow values = list.map (readvalue reader) (list.ofseq indices) values module memorymappedsimpleread = open system.io.memorymappedfiles allow readvalue (reader:memorymappedviewaccessor) offset cellindex = allow position = (cellindex*4l) - offset match reader.readint32(position) | int32.minvalue -> none | v -> some(v) allow readvalues filename indices = utilize mmf = memorymappedfile.createfromfile(filename, filemode.open) allow offset = (seq.min indices ) * 4l allow lastly = (seq.max indices) * 4l allow length = 4l+last-offset utilize reader = mmf.createviewaccessor(offset, length, memorymappedfileaccess.read) allow values = (list.ofseq indices) |> list.map (readvalue reader offset) values

for comparing here latest numpy version

class="lang-py prettyprint-override">import numpy np def convert(v): if v <> -2147483648: homecoming v else: homecoming none def read_values(filename, indices): values_arr = np.memmap(filename, dtype='int32', mode='r') homecoming map(convert, values_arr[indices])

update in contrary said before here, python still lot slower f# version due error in python tests appeared otherwise. leaving question here in case in depth knowledge of binaryreader or memorymappedfile knows improvements.

i managed simplereader 30% faster using reader.basestream.seek instead of reader.basestream.position. replaced lists arrays didn't alter lot.

the total code of simple reader now:

open scheme open system.io allow readvalue (reader:binaryreader) cellindex = // set stream right location reader.basestream.seek(int64 (cellindex*4), seekorigin.begin) |> ignore match reader.readint32() | int32.minvalue -> none | v -> some(v) allow readvalues indices filename = utilize reader = new binaryreader(file.open(filename, filemode.open, fileaccess.read, fileshare.read)) // utilize list or array forcefulness creation of values (otherwise reader gets disposed before values read) allow values = array.map (readvalue reader) indices values

but value in textfield not refresh until calling of roweditor.

i need set text value cell, without updating store. , if click cancel button of roweditor, need cell value returning old one.

thanks time, replies , help.

you can alter using selection model of grid,something :

{ text: 'type', dataindex: 'type', editor: { xtype: 'combo', typeahead: true, selectontab: true, displayfield:"name", listeners: { select: function(combo, records) { mygrid= this.up('grid'); var selectedmodel = this.up('grid').getselectionmodel().getselection()[0]; //selectedmodel.set('dataindexofnextcol', "success"); val = combo.getvalue(); if(val == 'type1'){ ext.getcmp('textfld').setvalue("success"); } else{ ext.getcmp('textfld').setvalue("failure"); } } }, { text: 'item', dataindex: 'item', editor: { xtype: 'textfield', id: 'textfld' } }

you have commit changes on update.so can phone call edit event listener,

listeners: { edit: function(editor, e) { e.record.commit(); } },

for reference , have @ demo

try instead:

also, aware while (!feof($f)) wrong. should check eof when reading file, not @ top of loop. way avoid processing empty lines.

while (!feof($f)) { $s = fgets($f); if (!$s) break; $arrm = preg_split('/[\r\n]+/',$s); : : }

im working on app users needs login to. coded in java, login works without problems. however, want receive "message" json , display it. said, code works, if json string "message" dosent contain special characters æ, ø, å. i've tried anything, also, have file gets info db , shows in listview, used exact same code, , works. json in login.php returns null, replaces whole string , replaces null.

my login.php (returning null)

<?php header('content-type:text/json;charset=utf-8'); $uname = $_post["txtuname"]; $pass = $_post["txtpass"]; $con=mysqli_connect("localhost","user","pass","db");// check connection if (mysqli_connect_errno()) { $response["success"] = 0; $response["message"] = "database error!"; die(json_encode($response)); echo "failed connect mysql: " . mysqli_connect_error(); } //mysql_query("set names 'utf8'", $con); mysql_query("set names 'utf8'"); $result = mysqli_query($con,"select * users email='$uname' , encrypted_password='$pass'"); while($row = mysqli_fetch_array($result)) { $response["success"] = 1; $response["message"] = $row['firstname'] .

my getdata.php (works)

<?php include "db_config.php"; $cat = $_get['app_category']; if($cat == '99'){ mysql_query("set names 'utf8'"); $sql=mysql_query("select * `test_fc`"); while($row=mysql_fetch_assoc($sql)) $output[]=$row; print ('{ "app_item":'); print(json_encode($output)); print ('}'); mysql_close(); } else { mysql_query("set names 'utf8'"); $sql=mysql_query("select * `test_fc` app_category={$cat}"); while($row=mysql_fetch_assoc($sql)) $output[]=$row; print ('{ "app_item":'); print(json_encode($output)); print ('}'); mysql_close(); } ?>

my java parser can read getdata.php without problem, special characters.

i've been stuck on past couple of days. help much appreciated!

edit: getting {"message":null,"success":}

the problem line:

mysql_query("set names 'utf8'");

you using mysql_* function while rest - , database connection - using mysqli_*. lead warning in php gets echoed out , invalidates json.

you should utilize either mysqli (preferred) or mysql (deprecated) not mix them.

android - Getting size from view that places inside a ViewGroup with GONE visibility (programatically it will be set as VISIBLE) -

android - Getting size from view that places inside a ViewGroup with GONE visibility (programatically it will be set as VISIBLE) -

i'm trying image photographic camera device, save it, , show preview in imageview.

my imageview (named imagepreview) defined within next layout:

<linearlayout android:id="@+id/ll_selected_image" android:layout_width="match_parent" android:layout_height="300dp" android:orientation="vertical" android:layout_gravity="center_horizontal" android:visibility="gone"> <!-- @ first gone --> <relativelayout android:layout_width="match_parent" android:layout_height="match_parent"> <imageview android:id="@+id/imagepreview" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_centerinparent="true"/> </relativelayout> </linearlayout>

when image acquired camera, seek scale image next this document, code is:

private void setpic() { // dimensions of view int targetw = mimageview.getwidth(); int targeth = mimageview.getheight(); // dimensions of bitmap bitmapfactory.options bmoptions = new bitmapfactory.options(); bmoptions.injustdecodebounds = true; bitmapfactory.decodefile(mcurrentphotopath, bmoptions); int photow = bmoptions.outwidth; int photoh = bmoptions.outheight; // determine how much scale downwards image int scalefactor = math.min(photow/targetw, photoh/targeth); // decode image file bitmap sized fill view bmoptions.injustdecodebounds = false; bmoptions.insamplesize = scalefactor; bmoptions.inpurgeable = true; bitmap bitmap = bitmapfactory.decodefile(mcurrentphotopath, bmoptions); mimageview.setimagebitmap(bitmap); }

the problem obtain "division zero" mimageview.getwidth(); , mimageview.getheight(); homecoming zero.

note visibility of parent linearlayout setted gone. then, application sets programmatically visible.

if remove gone, , add together visible instead, works good!

the unusual thing have tried add together in setpic(), first code lines, next code:

if(ivselectedimage.getvisibility() == view.visible) log.i(tag,"is visible!"); else if(ivselectedimage.getvisibility() == view.gone) log.i(tag,"is gone!"); else if(ivselectedimage.getvisibility() == view.invisible) log.i(tag,"is invisible!");

and prints in console "is visible"!

briefly: if set gone in xml, , set visible (programmatically) getheight() , getwidth() can't right value (also if when phone call these methods view visible). while, if set visible in xml, methods getheight() , getwidth() homecoming me right values.

you don't need utilize view size @ runtime example. based on code, while view visibility set gone main container, linearlayout, fixed height of 300dp. result, know 1 of dimensions of view since @ best android:layout_height="match_parent" can equal 300dp.

to scale need screen width - since main view (and nested relativelayout , imageview set match_parent). if you're in activity utilize this

display display = getwindowmanager().getdefaultdisplay(); point size = new point(); display.getsize(size); int width = size.x;

otherwise can display using

windowmanager wm = (windowmanager) context.getsystemservice(context.window_service); display display = wm.getdefaultdisplay();

just run calculation before need set image. store results sharedpreferences or , utilize ratio 300dp height , screen width scale image.

JavaScript dynamically detect all CSS values -

JavaScript dynamically detect all CSS values -

this script dynamically detects possible style properties element supports...

for (i in document.getelementbyid('body').style) { document.getelementbyid('q').value = document.getelementbyid('q').value+', '+i; }

my question how dynamically observe possible values given property supports? dynamic clearly mean not creating array possible values (static) , iterating on array using css.supports.

im not sure that's possible since endless. looking see classes of values acceptable.

when property value number top accepts length can in, cm, mm, pt, pc, px, ex, em, percentage, auto, or inherit

in case of content accepts different range of values normal, none, string's, uri's, counter, attr(attrname), open-quote, close-quote, no-open-quote, no-close-quote, inherit (and it's possible it's looking combination of things)

(src:w3.org)

each property described in w3 document has different set of types accepts.

i don't know how javascript spit out kind of schema/dtd come exhaustive list of potential values represent classes of values , test each using css.supports(propertyname,value);

c# - Select XElements from comma separated values -

c# - Select XElements from comma separated values -

i using linq-to-xml in project , want extract elements in comma separated string i.e.

here sample xml file

<?xml version="1.0" encoding="utf-8"?> <newdataset> <table> <entity>employee</entity> <entityid>2857</entityid> .. more nodes... .. more nodes... </table> <table> <entity>employee</entity> <entityid>2856</entityid> .. more nodes... .. more nodes... </table> ....... </newdataset>

here xelement:

xelement mainentities = xelement.load(strfilename); ienumerable<xelement> entityelements; entityelements = mainentities.elements("table").where(xtab => (string)xtab.element("entity").value == "employee");

and comma separated string

var filter = new list<string> { stremployeeids };

i tried

entityelements = mainentities.elements("table").where(xtab => (string)xtab.element("entity").value == "employee" && filter.contains((string)xtab.element("entityid").value));

but it's not working...

how can got elements in filter entityelements;

assuming stremployeeids defined this:

string stremployeeids = "1,2,3";

you need split string create list out of it:

string[] filter = stremployeeids.split(',');

javascript - Use ID from one page in JQuery -

i have dynamic html in page. want utilize id , info 1 js file other.

i have next html in care.js file

$('#chat-box').html( '<p style="margin-top:10px;">enter name</p><input type="text" id="chat-box-name" class="chat-editing" />' );

now want utilize info entered in above input box in chat.js.

is possible can usethe id/data 1 js file other in same project??

thanks

when code executes have element code child:

<div id="chat-box"> <p style="margin-top:10px;">enter name</p> <input type="text" id="chat-box-name" class="chat-editing" /> </div>

if create sure code sec javascript file gets executed after added content #chat-box can utilize javascript value of inputbox. assuming utilize jquery, did in question:

var input = $('#chat-box-name').val(); //the input

pure javascript:

var input = document.getelementbyid('chat-box-name').value;

c# - Exceptions lose part of stacktrace in try/catch context -

c# - Exceptions lose part of stacktrace in try/catch context -

i have 2 examples. in first case, debugger catches unhandled exception:

static void main(string[] args) { exec(); } static void exec() { throw new exception(); }

and exception has total stacktrace:

@ consoleapplication28.program.exec() @ consoleapplication28.program.main(string[] args) @ system.appdomain._nexecuteassembly(runtimeassembly assembly, string[] args) @ system.appdomain.executeassembly(string assemblyfile, evidence assemblysecurity, string[] args) @ microsoft.visualstudio.hostingprocess.hostproc.runusersassembly() @ system.threading.threadhelper.threadstart_context(object state) @ system.threading.executioncontext.runinternal(executioncontext executioncontext, contextcallback callback, object state, boolean preservesyncctx) @ system.threading.executioncontext.run(executioncontext executioncontext, contextcallback callback, object state, boolean preservesyncctx) @ system.threading.executioncontext.run(executioncontext executioncontext, contextcallback callback, object state) @ system.threading.threadhelper.threadstart()

the sec case:

static void main(string[] args) { exec(); } static void exec() { seek { throw new exception(); } grab (exception ex) { } // breakpoint }

at breakpoint exception has short stacktrace:

@ consoleapplication28.program.exec()

why stacktraces cutting containing method in sec case, , how prevent it? need total stacktrace bugreports, otherwise it's not possible find there problem is, without total stacktrace.

what you're seeing in visual studio debugger unhandled exception visual studio hosting process trapping (ie after first 2 stack frames part of vs "host plumbing"). if disable hosting process (project properties->enable visual studio hosting process), you'll see "short" stack trace in both scenarios (notwithstanding won't see stack frame main in sec case because exception "handled", not allowed propagate main). shorter stack trace stack trace see if running application outside debugger.

the stack works imagine - each method phone call pushes stack frame onto it, , @ end of method stack frame "popped", or removed stack. stack trace see on exception composed of stack frames frame exception thrown, frame exception handled, stack "unwound".

python - Print encoded string -

python - Print encoded string -

i'm developing own mp3 decoder using python i'm little bit stuck decoding id3 tag. don't want utilize existing libraries mutagen or eyed3 follow id3v2 specification.

the problem frame info encoded in format cannot print, using debugger see value "hideaway" it's preceded unusual characters can see here:

'data': '\\x00hideaway'

i have next questions: kind of encoding that? how can decode , print string? think other mp3 files utilize different encoding in id3 tags?

by way, i'm using utf-8 declaration @ top of file

# -*- coding: utf-8 -*-

and i'm reading file using normal i/o methods in python (read())

the characacters \\x00 indicate single byte value of 0 precedes h. so, string looks this:

class="lang-none prettyprint-override">zero - h - - d - e ...

usually character strings have letters or numbers in them, not zero. perhaps usage specific id3v2?

considering idc3v2 standard (http://id3.org/id3v2.4.0-structure), see is:

class="lang-none prettyprint-override">frames allow different types of text encoding contains text encoding description byte. possible encodings: $00 iso-8859-1 [iso-8859-1]. terminated $00. $01 utf-16 [utf-16] encoded unicode [unicode] bom. strings in same frame shall have same byteorder. terminated $00 00. $02 utf-16be [utf-16] encoded unicode [unicode] without bom. terminated $00 00. $03 utf-8 [utf-8] encoded unicode [unicode]. terminated $00.

so, see 0 byte indicates iso-8859-1 encoding, next 0 byte.

your programme might deal so:

class="lang-python prettyprint-override">title = fp.read(number_of_bytes) if(title[0] == '\x00') title = title[1:].decode('iso8859-1') elif(title[0] == ... else ...) title = title[1:].decode('some-other-encoding') ...

there no problem function prodlist not show value instead alert gives me junk jquery : tried this: $('#prodlist option:selected').text; not have selected value prodlist too, , instead alert gives me junk jquery .

try this:

create property in viewmodel store selected value dropdownlist

shell - OSX autotools: `aclocal.m4' not being output by `autom4te' -

shell - OSX autotools: `aclocal.m4' not being output by `autom4te' -

i have been trying build freetype2 library in osx mavericks several weeks now, without success.

the problem using gnu autotools create configure build script.

i have installed automake, autoconf, libtoolize, m4 , perl5 using macports port command.

when executing aclocal, there supposed file created in configure directory contains autotools macros: aclocal.m4. however, file not beingness output, , subsequent glibtoolize , autoconf commands generating spurious configure script.

the result is: no aclocal.m4 file, , usual contents of ./autom4te.cache/traces.* beingness dumped @ top of generated configure file (the traces.* files empty).

e.g.:

m4trace:configure.ac:14: -1- ac_subst([shell]) m4trace:configure.ac:14: -1- ac_subst_trace([shell]) m4trace:configure.ac:14: -1- m4_pattern_allow([^shell$])

any help appreciated.

gnu autotools not back upwards execution on working directory stored on fat32 file system. results in spurious m4trace debug messages beingness output generated configure script.

it unknown why is, may related reliance on sleep command check whether file has changed. fat32 rounds time stamps nearest second, execution , subsequent modification checks may happen on sub-second timescale.

this has been raised development team, now, move working directory osx boot partition before executing gnu autotools.

objective c - NSImageView size vs NSImage size -

objective c - NSImageView size vs NSImage size -

does size of image used nsimageview need same dimensions image view?

as example, when have icon image dimensions 64px 64px create sure nsimageview displays image 64px 64px. however, if have nsimageview 48px 48px create sure have image 48px 48px image view. both of these images same icon, 1 larger other. instead of having 2 separate images in app (which can increment app size if there lot of images), wondering if have 1 image (the 64x64 image) , utilize larger image smaller sized nsimageviews.

no, don't need same size. can alter nsimageview's imagescaling , imagealignment ensure nsimage resizes nicely fill nsimageview.

see apple's documentation farther details.

gives me

i satisfied plot get, out of curiosity, there alternative automatically alter log base of operations of log scale?

as christoph said there no alternative in octave or matlab. may automate little bit process, , ensure consistency between ticks positions , labels, explained here.

for instance

x = 1:100; y = 2 .^ x; semilogy(x, y); base of operations = 2; tick_exponents = 0:20:100; set(gca, 'ytick', base of operations .^ tick_exponents); format_string = sprintf('%d^{%%d}', base); tick_labels = num2str(tick_exponents(:), format_string) set(gca, 'yticklabel', tick_labels);

which yields

c++ - Confused about behaviour of shaders in OpenGL - switching declarations creates errors and crashes -

c++ - Confused about behaviour of shaders in OpenGL - switching declarations creates errors and crashes -

i'm creating functions load shaders, create meshes, , like, started simple programme test functionalities adding, 1 one, , found problem bit:

const char* vertexshader = prm.loadshader ( "simple_vs.glsl" ).c_str (); const char* fragmentshader = prm.loadshader ( "simple_fs.glsl" ).c_str (); gluint vs = glcreateshader ( gl_vertex_shader ); glshadersource ( vs, 1, &vertexshader, null ); glcompileshader ( vs ); gluint fs = glcreateshader ( gl_fragment_shader ); glshadersource ( fs, 1, &fragmentshader, null ); glcompileshader ( fs );

if tried compile it, no errors, there black screen. if removed fragment shader, display triangle, meant to, without colors. if switched 2 declarations, in:

const char* fragmentshader = prm.loadshader ( "simple_fs.glsl" ).c_str (); const char* vertexshader = prm.loadshader ( "simple_vs.glsl" ).c_str ();

i error, , programme crash:

error code #3: shader info shader 1: warning: 0:1: '#version' : version number deprecated in ogl 3.0 forwards compatible context driver error: 0:1: '#extension' : 'gl_arb_separate_shader_objects' not supported

however, if set this:

const char* vertexshader = prm.loadshader ( "simple_vs.glsl" ).c_str (); gluint vs = glcreateshader ( gl_vertex_shader ); glshadersource ( vs, 1, &vertexshader, null ); glcompileshader ( vs ); const char* fragmentshader = prm.loadshader ( "simple_fs.glsl" ).c_str (); gluint fs = glcreateshader ( gl_fragment_shader ); glshadersource ( fs, 1, &fragmentshader, null ); glcompileshader ( fs );

it works fine. clueless why case, ran original code no issues in prior versions of program. checked prm.loadshader function, works fine, , returns expected value. none of changes have made programme deal shaders, confused bizzarely particular behaviour. can more experience explain why happening?

presumably prm.loadshader returns std::string value. calling c_str gives internal character storage of std::string, lives long std::string does. end of each of loadshader lines, std::string returned destroyed because temporary object, , pointers you've stored no longer pointing @ valid character arrays.

you can around storing local re-create of returned strings.

std::string vertexshader = prm.loadshader ( "simple_vs.glsl" ); const char* cvertexshader = vertexshader.c_str(); std::string fragmentshader = prm.loadshader ( "simple_fs.glsl" ); const char* cfragmentshader = vertexshader.c_str(); gluint vs = glcreateshader ( gl_vertex_shader ); glshadersource ( vs, 1, &cvertexshader, null ); glcompileshader ( vs ); gluint fs = glcreateshader ( gl_fragment_shader ); glshadersource ( fs, 1, &cfragmentshader, null ); glcompileshader ( fs );

java - Android NullPointerException while instantiating ViewPager Fragments onCreateView but not when swyping views -

i trying fill view pager fragments ability swype between different fragments. @ moment, when fragment calls oncreateview() nullpointerexception thrown while trying set text in textview, weirdly, if grab exception can swype through other fragments display correctly.

note: first , sec items not render in viewpager, if swype lastly fragment 1 time again display correctly.

here fragment class:

public class myfragment extends fragment { public static final string extra_message = "extra_message"; public static logiccontroller controller; public static mainactivity activity; public static final myfragment newinstance(string message, logiccontroller controller, mainactivity activity) { myfragment.activity = activity; myfragment.controller = controller; myfragment f = new myfragment(); bundle bdl = new bundle(1); bdl.putstring(extra_message, message); f.setarguments(bdl); homecoming f; } @override public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) { seek { string message = getarguments().getstring(extra_message); // view v = inflater.inflate(r.layout.myfragment_layout, container, false); view v = activity.getlayoutinflater().inflate(r.layout.myfragment_layout, null); // view mainview = pager; textview messagetextview = (textview)v.findviewbyid(r.id.testertextview); system.out.println(controller.getupdategeonetworkdelay() + messagetextview.gettext().tostring()); messagetextview.settext(message); homecoming v; } grab (exception e) { e.printstacktrace(); homecoming null; } } }

here fragment pager adapter:

public class mainpageadapter extends fragmentpageradapter { private list<fragment> fragments; public mainpageadapter(fragmentmanager fm, list<fragment> fragments) { super(fm); this.fragments = fragments; } @override public fragment getitem(int position) { fragment frag = this.fragments.get(position); system.out.println("fragment: " + frag + " pos: " + position); homecoming frag; } @override public int getcount() { homecoming this.fragments.size(); } }

the exception thrown on line:

messagetextview.settext(message);

i have reason believe problem due not referencing textview beyond level of expertise.

thanks help.

please check line :

system.out.println(controller.getupdategeonetworkdelay() + messagetextview.gettext().tostring()); messagetextview.settext(message);

my guess message content of arguments in bundle passed newinstance should this:

messagetextview.settext(getarguments().getstringextra(extra_message,"message not passed"));

also final modifier public static final myfragment newinstance in line seems inappropriate remove it.
