After you extract the classes.dex file, just drag and drop it to d2j-dex2jar

You first have to tell Gnuplot to use a style that uses points, e.g. with points or with linespoints. Try for example:

plot sin(x) with points

Output:

Now try:

plot sin(x) with points pointtype 5

Output:

You may also want to look at the output from the test command which shows you the capabilities of the current terminal. Here are the capabilities for my pngairo terminal:

I'm running Chrome version 60 and none of the previous CSS answers worked.

I found that Chrome was adding the blue highlight via the outline style. Adding the following CSS fixed it for me:

:focus {
    outline: none !important;
}

Peeskillet's lame tutorial for working with JTables in Netbeans GUI Builder

• Set the table column headers
  1. Highglight the table in the design view then go to properties pane on the very right. Should be a tab that says "Properties". Make sure to highlight the table and not the scroll pane surrounding it, or the next step wont work
  2. Click on the ... button to the right of the property model. A dialog should appear.
  3. Set rows to 0, set the number of columns you want, and their names.

• Add a button to the frame somwhere,. This button will be clicked when the user is ready to submit a row

  1. Right-click on the button and select Events -> Action -> actionPerformed

  2. You should see code like the following auto-generated

     private void jButton1ActionPerformed(java.awt.event.ActionEvent) {}
     

• The jTable1 will have a DefaultTableModel. You can add rows to the model with your data

  private void jButton1ActionPerformed(java.awt.event.ActionEvent) {
      String data1 = something1.getSomething();
      String data2 = something2.getSomething();
      String data3 = something3.getSomething();
      String data4 = something4.getSomething();
  
      Object[] row = { data1, data2, data3, data4 };
  
      DefaultTableModel model = (DefaultTableModel) jTable1.getModel();
  
      model.addRow(row);
  
      // clear the entries.
  }
  

So for every set of data like from a couple text fields, a combo box, and a check box, you can gather that data each time the button is pressed and add it as a row to the model.

Dump an entire database to a file:

mysqldump -u USERNAME -p password DATABASENAME > FILENAME.sql

Ok, to remove all variables, maybe the prettiest is

$url = strtok($url, '?');

See about strtok here.

Its the fastest (see below), and handles urls without a '?' properly.

To take a url+querystring and remove just one variable (without using a regex replace, which may be faster in some cases), you might do something like:

function removeqsvar($url, $varname) {
    list($urlpart, $qspart) = array_pad(explode('?', $url), 2, '');
    parse_str($qspart, $qsvars);
    unset($qsvars[$varname]);
    $newqs = http_build_query($qsvars);
    return $urlpart . '?' . $newqs;
}

A regex replace to remove a single var might look like:

function removeqsvar($url, $varname) {
    return preg_replace('/([?&])'.$varname.'=[^&]+(&|$)/','$1',$url);
}

Heres the timings of a few different methods, ensuring timing is reset inbetween runs.

You don't have to cram multiple operations into one stream/lambda. Consider separating them into 2 statements (using static import of toList()):

entryList.forEach(e->e.setTempId(tempId));

List<Entry> updatedEntries = entryList.stream()
  .map(e->entityManager.update(entry, entry.getId()))

The python-ldap is based on OpenLDAP, so you need to have the development files (headers) in order to compile the Python module. If you're on Ubuntu, the package is called libldap2-dev.

Debian/Ubuntu:

sudo apt-get install libsasl2-dev python-dev libldap2-dev libssl-dev

RedHat/CentOS:

sudo yum install python-devel openldap-devel

PHP 7.1.0 has introduced the iterable pseudo-type and the is_iterable() function, which is specially designed for such a purpose:

This […] proposes a new iterable pseudo-type. This type is analogous to callable, accepting multiple types instead of one single type.

iterable accepts any array or object implementing Traversable. Both of these types are iterable using foreach and can be used with yield from within a generator.

function foo(iterable $iterable) {
    foreach ($iterable as $value) {
        // ...
    }
}

This […] also adds a function is_iterable() that returns a boolean: true if a value is iterable and will be accepted by the iterable pseudo-type, false for other values.

var_dump(is_iterable([1, 2, 3])); // bool(true)
var_dump(is_iterable(new ArrayIterator([1, 2, 3]))); // bool(true)
var_dump(is_iterable((function () { yield 1; })())); // bool(true)
var_dump(is_iterable(1)); // bool(false)
var_dump(is_iterable(new stdClass())); // bool(false)

You can also use the function is_array($var) to check if the passed variable is an array:

<?php
    var_dump( is_array(array()) ); // true
    var_dump( is_array(array(1, 2, 3)) ); // true
    var_dump( is_array($_SERVER) ); // true
?>

You need to escape the quotes in the string by adding a backslash \ before ".

Like:

"<font color=\"red\">"

I discovered that this behaviour only occurs after running a particular script, similar to the one in the question. I have no idea why it occurs.

It works (refreshes the graphs) if I put

plt.clf()
plt.cla()
plt.close()

after every plt.show()

JSONObject typically uses HashMap internally to store the data. So, you can use it as Map in your code.

Example,

JSONObject obj = JSONObject.fromObject(strRepresentation);
Iterator i = obj.entrySet().iterator();
while (i.hasNext()) {
   Map.Entry e = (Map.Entry)i.next();
   System.out.println("Key: " + e.getKey());
   System.out.println("Value: " + e.getValue());
}

Functional approach. Returns array of all matched elements and trims spaces around while checking.

function getElementsByText(str, tag = 'a') {
  return Array.prototype.slice.call(document.getElementsByTagName(tag)).filter(el => el.textContent.trim() === str.trim());
}

Usage

getElementsByText('Text here'); // second parameter is optional tag (default "a")

if you're looking through different tags i.e. span or button

getElementsByText('Text here', 'span');
getElementsByText('Text here', 'button');

The default value tag = 'a' will need Babel for old browsers

If #button_id implies a standard HTML button (like a submit button) you can use the 'disabled' attribute to make the button inactive to the browser.

$("#button_id").click(function() {
    $('#button_id').attr('disabled', 'true');

    //do something

     $('#button_id').removeAttr('disabled');
});   

What you may need to be careful with, however, is the order in which these things may happen. If you are using the jquery hide command, you may want to include the "$('#button_id').removeAttr('disabled');" as part of a call back, so that it does not happen until the hide is complete.

[edit] example of function using a callback:

$("#button_id").click(function() {
    $('#button_id').attr('disabled', 'true');
    $('#myDiv').hide(function() { $('#button_id').removeAttr('disabled'); });
});   

I'll make the @zyxue answer a bit more explicit:

RE_D = re.compile('\d')

def has_digits(string):
    res = RE_D.search(string)
    return res is not None

has_digits('asdf1')
Out: True

has_digits('asdf')
Out: False

which is the solution with the fastest benchmark from the solutions that @zyxue proposed on the answer.

I am on Ubuntu 18.04 and got the same error, was worried for weeks too. Finally realized that gpg2 is not pointing towards anything. So simply run

git config --global gpg.program gpg

And tada, it works like charm.

Your commits will now have verified tag with them.

You should find installed packages in :

anaconda's directory / lib / site_packages

That's where i found mine.

Use the Equals method:

object value2 = null;
Console.WriteLine(object.Equals(value2,null));

Brackets are used around identifiers, so your code will look for the field %'% in the Header table. You want to use a string insteaed. To put an apostrophe in a string literal you use double apostrophes.

SELECT *
FROM Header WHERE userID LIKE '%''%'

minrk's answer is right.

However, I found that the images appeared broken in Print View (on my Windows machine running the Anaconda distribution of IPython version 0.13.2 in a Chrome browser)

The workaround for this was to use <img src="../files/image.png"> instead.

This made the image appear correctly in both Print View and the normal iPython editing view.

UPDATE: as of my upgrade to iPython v1.1.0 there is no more need for this workaround since the print view no longer exists. In fact, you must avoid this workaround since it prevents the nbconvert tool from finding the files.

use this if your email column contains empty values

 select * from table where email in (
    select email from table group by email having count(*) > 1 and email != ''

•   is the character entity reference (meant to be easily parseable by humans).
•   is the numeric entity reference (meant to be easily parseable by machines).

They are the same except for the fact that the latter does not need another lookup table to find its actual value. The lookup table is called a DTD, by the way.

You can read more about character entity references in the offical W3C documents.

It is because of this line:

printf ("Hi %s,</br />", $name);

You should not print/echo anything before sending the headers.

Look in the file Microsoft.Common.targets

The answer to the question is in the file Microsoft.Common.targets for your target framework version.

For .Net Framework version 4.0 (and 4.5 !) the AssemblySearchPaths-element is defined like this:

    <!--
    The SearchPaths property is set to find assemblies in the following order:

        (1) Files from current project - indicated by {CandidateAssemblyFiles}
        (2) $(ReferencePath) - the reference path property, which comes from the .USER file.
        (3) The hintpath from the referenced item itself, indicated by {HintPathFromItem}.
        (4) The directory of MSBuild's "target" runtime from GetFrameworkPath.
            The "target" runtime folder is the folder of the runtime that MSBuild is a part of.
        (5) Registered assembly folders, indicated by {Registry:*,*,*}
        (6) Legacy registered assembly folders, indicated by {AssemblyFolders}
        (7) Resolve to the GAC.
        (8) Treat the reference's Include as if it were a real file name.
        (9) Look in the application's output folder (like bin\debug)
    -->
<AssemblySearchPaths Condition=" '$(AssemblySearchPaths)' == ''">
  {CandidateAssemblyFiles};
  $(ReferencePath);
  {HintPathFromItem};
  {TargetFrameworkDirectory};
  {Registry:$(FrameworkRegistryBase),$(TargetFrameworkVersion),$(AssemblyFoldersSuffix)$(AssemblyFoldersExConditions)};
  {AssemblyFolders};
  {GAC};
  {RawFileName};
  $(OutDir)
</AssemblySearchPaths>

For .Net Framework 3.5 the definition is the same, but the comment is wrong. The 2.0 definition is slightly different, it uses $(OutputPath) instead of $(OutDir).

On my machine I have the following versions of the file Microsoft.Common.targets:

C:\Windows\Microsoft.NET\Framework\v2.0.50727\Microsoft.Common.targets
C:\Windows\Microsoft.NET\Framework\v3.5\Microsoft.Common.targets
C:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets

C:\Windows\Microsoft.NET\Framework64\v2.0.50727\Microsoft.Common.targets
C:\Windows\Microsoft.NET\Framework64\v3.5\Microsoft.Common.targets
C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Microsoft.Common.targets

This is with Visual Studio 2008, 2010 and 2013 installed on Windows 7.

The fact that the output directory is searched can be a bit frustrating (as the original poster points out) because it may hide an incorrect HintPath. The solution builds OK on your local machine, but breaks when you build on in a clean folder structure (e.g. on the build machine).

you can use list extend method, it shows to be the fastest:

flat_list = []
for sublist in l:
    flat_list.extend(sublist)

performance:

import functools
import itertools
import numpy
import operator
import perfplot



def functools_reduce_iconcat(a):
    return functools.reduce(operator.iconcat, a, [])


def itertools_chain(a):
    return list(itertools.chain.from_iterable(a))


def numpy_flat(a):
    return list(numpy.array(a).flat)


def extend(a):
    n = []

    list(map(n.extend, a))

    return n 


perfplot.show(
    setup=lambda n: [list(range(10))] * n,
    kernels=[
        functools_reduce_iconcat, extend,itertools_chain, numpy_flat
        ],
    n_range=[2**k for k in range(16)],
    xlabel='num lists',
    )

output:

Try this

int numberOfRecords = dtFoo.Select("IsActive = 'Y'").Count<DataRow>();    
Console.WriteLine("Count: " + numberOfRecords.ToString());

You can cut using following ,
-d: delimiter ,-f for fields
\t used for tab separated fields

cut -d$'\t' -f 1-3,7-

<body oncontextmenu="return false" onselectstart="return false" ondragstart="return false" >

Set these attributes in your selected tag

No Need JQuery (like)

So actually, my comment that you should do a console.log(el.nativeElement) should have pointed you in the right direction, but I didn't expect the output to be just a string representing the DOM Element.

What you have to do to inspect it in the way it helps you with your problem, is to do a console.log(el) in your example, then you'll have access to the nativeElement object and will see a property called innerHTML.

Which will lead to the answer to your original question:

let myCurrentContent:string = el.nativeElement.innerHTML; // get the content of your element
el.nativeElement.innerHTML = 'my new content'; // set content of your element

Update for better approach:

Since it's the accepted answer and web workers are getting more important day to day (and it's considered best practice anyway) I want to add this suggestion by Mark Rajcok here.

The best way to manipulate DOM Elements programmatically is using the Renderer:

constructor(private _elemRef: ElementRef, private _renderer: Renderer) { 
    this._renderer.setElementProperty(this._elemRef.nativeElement, 'innerHTML', 'my new content');
}

Edit

Since Renderer is deprecated now, use Renderer2 instead with setProperty

Update:

This question with its answer explained the console.log behavior.

Which means that console.dir(el.nativeElement) would be the more direct way of accessing the DOM Element as an "inspectable" Object in your console for this situation.

Hope this helped.

For anyone wondering how to do it in cordova hybrid app:

• go to index.js -> inside the function onDeviceReady() write :

    subscribe();
  

(It's important to write it at the top of the function!)

• then, in the same file (index.js) find :

  function subscribe(){

   FirebasePlugin.subscribe("write_here_your_topic", function(){
  
   },function(error){
  
       logError("Failed to subscribe to topic", error);
   });
   }
  

and write your own topic here -> "write_here_your_topic"

Might be worth looking at Google Breakpad, a cross-platform crash dump generator and tools to process the dumps.

First the bad answer. From this question there's a one-liner that you can run:

echo "" > $(docker inspect --format='{{.LogPath}}' <container_name_or_id>)

instead of echo, there's the simpler:

: > $(docker inspect --format='{{.LogPath}}' <container_name_or_id>)

or there's the truncate command:

truncate -s 0 $(docker inspect --format='{{.LogPath}}' <container_name_or_id>)

I'm not a big fan of either of those since they modify Docker's files directly. The external log deletion could happen while docker is writing json formatted data to the file, resulting in a partial line, and breaking the ability to read any logs from the docker logs cli. For an example of that happening, see this comment on duketwo's answer

Instead, you can have Docker automatically rotate the logs for you. This is done with additional flags to dockerd if you are using the default JSON logging driver:

dockerd ... --log-opt max-size=10m --log-opt max-file=3

You can also set this as part of your daemon.json file instead of modifying your startup scripts:

{
  "log-driver": "json-file",
  "log-opts": {"max-size": "10m", "max-file": "3"}
}

These options need to be configured with root access. Make sure to run a systemctl reload docker after changing this file to have the settings applied. This setting will then be the default for any newly created containers. Note, existing containers need to be deleted and recreated to receive the new log limits.

Similar log options can be passed to individual containers to override these defaults, allowing you to save more or fewer logs on individual containers. From docker run this looks like:

docker run --log-driver json-file --log-opt max-size=10m --log-opt max-file=3 ...

or in a compose file:

version: '3.7'
services:
  app:
    image: ...
    logging:
      options:
        max-size: "10m"
        max-file: "3"

For additional space savings, you can switch from the json log driver to the "local" log driver. It takes the same max-size and max-file options, but instead of storing in json it uses a binary syntax that is faster and smaller. This allows you to store more logs in the same sized file. The daemon.json entry for that looks like:

{
  "log-driver": "local",
  "log-opts": {"max-size": "10m", "max-file": "3"}
}

The downside of the local driver is external log parsers/forwarders that depended on direct access to the json logs will no longer work. So if you use a tool like filebeat to send to Elastic, or Splunk's universal forwarder, I'd avoid the "local" driver.

I've got a bit more on this in my Tips and Tricks presentation.

The correct syntax to do this on your relations is:

Event::whereHas('participants', function ($query) {
    return $query->where('IDUser', '=', 1);
})->get();

Using an iframe to "render" a PDF will not work on all browsers; it depends on how the browser handles PDF files. Some browsers (such as Firefox and Chrome) have a built-in PDF rendered which allows them to display the PDF inline where as some older browsers (perhaps older versions of IE attempt to download the file instead).

Instead, I recommend checking out PDFObject which is a Javascript library to embed PDFs in HTML files. It handles browser compatibility pretty well and will most likely work on IE8.

In your HTML, you could set up a div to display the PDFs:

<div id="pdfRenderer"></div>

Then, you can have Javascript code to embed a PDF in that div:

var pdf = new PDFObject({
  url: "https://something.com/HTC_One_XL_User_Guide.pdf",
  id: "pdfRendered",
  pdfOpenParams: {
    view: "FitH"
  }
}).embed("pdfRenderer");

You can get raw data using below method. BTW, this pattern is for Java 6. If you are using Java 7 or newer, please consider try-with-resources pattern.

public String getJSON(String url, int timeout) {
    HttpURLConnection c = null;
    try {
        URL u = new URL(url);
        c = (HttpURLConnection) u.openConnection();
        c.setRequestMethod("GET");
        c.setRequestProperty("Content-length", "0");
        c.setUseCaches(false);
        c.setAllowUserInteraction(false);
        c.setConnectTimeout(timeout);
        c.setReadTimeout(timeout);
        c.connect();
        int status = c.getResponseCode();

        switch (status) {
            case 200:
            case 201:
                BufferedReader br = new BufferedReader(new InputStreamReader(c.getInputStream()));
                StringBuilder sb = new StringBuilder();
                String line;
                while ((line = br.readLine()) != null) {
                    sb.append(line+"\n");
                }
                br.close();
                return sb.toString();
        }

    } catch (MalformedURLException ex) {
        Logger.getLogger(getClass().getName()).log(Level.SEVERE, null, ex);
    } catch (IOException ex) {
        Logger.getLogger(getClass().getName()).log(Level.SEVERE, null, ex);
    } finally {
       if (c != null) {
          try {
              c.disconnect();
          } catch (Exception ex) {
             Logger.getLogger(getClass().getName()).log(Level.SEVERE, null, ex);
          }
       }
    }
    return null;
}

And then you can use returned string with Google Gson to map JSON to object of specified class, like this:

String data = getJSON("http://localhost/authmanager.php");
AuthMsg msg = new Gson().fromJson(data, AuthMsg.class);
System.out.println(msg);

There is a sample of AuthMsg class:

public class AuthMsg {
    private int code;
    private String message;

    public int getCode() {
        return code;
    }
    public void setCode(int code) {
        this.code = code;
    }

    public String getMessage() {
        return message;
    }
    public void setMessage(String message) {
        this.message = message;
    }
}

JSON returned by http://localhost/authmanager.php must look like this:

{"code":1,"message":"Logged in"}

You can add .a file in the linking command:

  gcc yourfiles /path/to/library/libLIBRARY.a

But this is not talking with gcc driver, but with ld linker as options like -Wl,anything are.

When you tell gcc or ld -Ldir -lLIBRARY, linker will check both static and dynamic versions of library (you can see a process with -Wl,--verbose). To change order of library types checked you can use -Wl,-Bstatic and -Wl,-Bdynamic. Here is a man page of gnu LD: http://linux.die.net/man/1/ld

To link your program with lib1, lib3 dynamically and lib2 statically, use such gcc call:

gcc program.o -llib1 -Wl,-Bstatic -llib2 -Wl,-Bdynamic -llib3

Assuming that default setting of ld is to use dynamic libraries (it is on Linux).

You need to explicitly tell the data type or the type can be inferred when you declare anything in Swift.

The sample below declare a dictionary with key as a Int type and the value as a String type.

Method 1: Initializer

let dic = Dictionary<Int, String>()

Method 2: Shorthand Syntax

let dic = [Int:String]()

Method 3: Dictionary Literal

var dic = [1: "Sample"]
// dic has NOT to be a constant
dic.removeAll()

Step 1: Find server which are running: ps aux | grep puma Step 2: Kill those server Kill -9 [server number]

--Gets the size of each index for the specified table
DECLARE @TableName sysname = N'SomeTable';

SELECT i.name AS IndexName
      ,8 * SUM(s.used_page_count) AS IndexSizeKB
FROM sys.indexes AS i
    INNER JOIN sys.dm_db_partition_stats AS s 
        ON i.[object_id] = s.[object_id] AND i.index_id = s.index_id
WHERE s.[object_id] = OBJECT_ID(@TableName, N'U')
GROUP BY i.name
ORDER BY i.name;

SELECT i.name AS IndexName
      ,8 * SUM(a.used_pages) AS IndexSizeKB
FROM sys.indexes AS i
    INNER JOIN sys.partitions AS p 
        ON i.[object_id]  = p.[object_id] AND i.index_id = p.index_id
    INNER JOIN sys.allocation_units AS a 
        ON p.partition_id = a.container_id
WHERE i.[object_id] = OBJECT_ID(@TableName, N'U')
GROUP BY i.name
ORDER BY i.name;

I would like to add that if you're trying to get all of the check-boxes with that name that have been selected, you would want to use the following syntax:

$("[name='bla[]']:checked").each(function () {
    // do stuff
});

Make sure there is not a space between the closing ] and :checked

I wish I had my cable handy. I know you can telnet to the emulator to change its location

$ telnet localhost 5554
Android Console: type 'help' for a list of commands
OK
geo fix -82.411629 28.054553
OK

I cannot remember if you can telnet to your device, but I think you can. I hope this helps.

You'll need adb (android debugging bridge) for this (CLI).

As explained in the documentation, by using an @RequestParam annotation:

public @ResponseBody String byParameter(@RequestParam("foo") String foo) {
    return "Mapped by path + method + presence of query parameter! (MappingController) - foo = "
           + foo;
}

Press in cmd or bash : Ctrl + C

For me, just setting the compatibility level to higher level works fine. To see C.Level :

select compatibility_level from sys.databases where name = [your_database]

Try this code, Let $ be defined

(function ($, Drupal) {

  'use strict';

  Drupal.behaviors.module_name = {
    attach: function (context, settings) {
        jQuery(document).ready(function($) {
      $("#search_text").autocomplete({
          source:results,
          minLength:2,
          position: { offset:'-30 0' },  
          select: function(event, ui ) { 
                  goTo(ui.item.value);
                  return false;
          }        
        }); 
        });
   }
  };
})(jQuery, Drupal);

I've been usually doing generic filtering over rows like this:

criterion = lambda row: row['countries'] not in countries
not_in = df[df.apply(criterion, axis=1)]

Html

<img id="imgElem"></img>

Js

string baseStr64="/9j/4AAQSkZJRgABAQE...";
imgElem.setAttribute('src', "data:image/jpg;base64," + baseStr64);

As a side note, consider passing strings in setWord() as const references to avoid excess copying. Also, in displayWord, consider making this a const function to follow const-correctness.

void setWord(const std::string& word) {
  theWord = word;
}

Normally you want to perform this check atomically with using the result, so stat() is useless. Instead, open() the file read-only first and use fstat(). If it's a directory, you can then use fdopendir() to read it. Or you can try opening it for writing to begin with, and the open will fail if it's a directory. Some systems (POSIX 2008, Linux) also have an O_DIRECTORY extension to open which makes the call fail if the name is not a directory.

Your method with opendir() is also good if you want a directory, but you should not close it afterwards; you should go ahead and use it.

A simple solution for you if you're new to HTML, is just to use a table to line everything up.

<form>
  <table>
    <tr>
      <td align="right">First Name:</td>
      <td align="left"><input type="text" name="first" /></td>
    </tr>
    <tr>
      <td align="right">Last Name:</td>
      <td align="left"><input type="text" name="last" /></td>
    </tr>
    <tr>
      <td align="right">Email:</td>
      <td align="left"><input type="text" name="email" /></td>
    </tr>
  </table>
</form>

You can use the LIKE operator to compare the content of a T-SQL string, e.g.

SELECT * FROM [table] WHERE [field] LIKE '%stringtosearchfor%'.

The percent character '%' is a wild card- in this case it says return any records where [field] at least contains the value "stringtosearchfor".

The ubuntu package name is qt5-default, not qt.

brew install imagemagick

Don't forget to install also gs which is a dependency if you want to convert pdf to images for example :

brew install ghostscript

Instead of use img src="", try to create a div and set background-image as the image you want.

Right now it's working for me.

example:

App.js

import React, { Component } from 'react';
import './App.css';



class App extends Component {

  render() {
    return (
      <div>
        <div className="myImage"> </div>
      </div>
    );
  }
}

export default App;

App.css

.myImage {
  width: 60px;
  height: 60px;
  background-image: url("./icons/add-circle.png");
  background-repeat: no-repeat;
  background-size: 100%;
}

You need this:

$('.container').each(function(){  
     var $columns = $('.column',this);
     var maxHeight = Math.max.apply(Math, $columns.map(function(){
         return $(this).height();
     }).get());
     $columns.height(maxHeight);
});

Explanation

• The following snippet constructs an array of the heights:

  $columns.map(function(){
      return $(this).height();
  }).get()
  

• Math.max.apply( Math, array ) finds the maximum of array items

• $columns.height(maxHeight); sets all columns' height to maximum height.

Live demo

ResourceManager shouldn't be needed unless you're loading from an external resource.
For most things, say you've created a project (DLL, WinForms, whatever) you just use the project namespace, "Resources" and the resource identifier. eg:

Assuming a project namespace: UberSoft.WidgetPro

And your resx contains:

You can just use:

Ubersoft.WidgetPro.Properties.Resources.RESPONSE_SEARCH_WILFRED

In the first two cases, you simply forgot to actually call the member function (!, it's not a value) std::vector<int>::size like this:

#include <vector>

int main () {
    std::vector<int> v;
    auto size = v.size();
}

Your third call

int size = v.size();

triggers a warning, as not every return value of that function (usually a 64 bit unsigned int) can be represented as a 32 bit signed int.

int size = static_cast<int>(v.size());

would always compile cleanly and also explicitly states that your conversion from std::vector::size_type to int was intended.

Note that if the size of the vector is greater than the biggest number an int can represent, size will contain an implementation defined (de facto garbage) value.

Maybe you can use pandas crosstab function

test5 = pd.crosstab(index=faultdf['Site Name'], columns=faultdf[''Abuse/NFF''])

test5.plot(kind='bar', stacked=True)

div hover background color change

Try like this:

.class_name:hover{
    background-color:#FF0000;
}

you can wrap -Andrie answer into a generic function

mbind<-function(...){
 Reduce( function(x,y){cbind(x,y[match(row.names(x),row.names(y)),])}, list(...) )
}

Here, you can bind multiple frames with rownames as key

I've found FileFormat.info's Unicode Character Search to be most helpful in finding exact character codes.

Entering simply ' (the character to the left of the return key on my US Mac keyboard) into their search yields several results of various curls and languages.

I would presume the original question was asking for the typographically correct U+02BC ', rather than the typewriter fascimile U+0027 '.

The W3C recommends hex codes for HTML entities (see below). For U+02BC that would be ʼ, rather than ' for U+0027.

http://www.w3.org/International/questions/qa-escapes

Using character escapes in markup and CSS

Hex vs. decimal. Typically when the Unicode Standard refers to or lists characters it does so using a hexadecimal value. … Given the prevalence of this convention, it is often useful, though not required, to use hexadecimal numeric values in escapes rather than decimal values…

http://www.w3.org/TR/html4/charset.html

5 HTML Document Representation … 5.4 Undisplayable characters

…If missing characters are presented using their numeric representation, use the hexadecimal (not decimal) form, since this is the form used in character set standards.

Let's pretend you have HTML like this

<input type="radio" name="gender" id="gender_Male" value="Male" />
<input type="radio" name="gender" id="gender_Female" value="Female" />

For client-side validation, here's some Javascript to check which one is selected:

if(document.getElementById('gender_Male').checked) {
  //Male radio button is checked
}else if(document.getElementById('gender_Female').checked) {
  //Female radio button is checked
}

The above could be made more efficient depending on the exact nature of your markup but that should be enough to get you started.

If you're just looking to see if any radio button is selected anywhere on the page, PrototypeJS makes it very easy.

Here's a function that will return true if at least one radio button is selected somewhere on the page. Again, this might need to be tweaked depending on your specific HTML.

function atLeastOneRadio() {
    return ($('input[type=radio]:checked').size() > 0);
}

For server-side validation (remember, you can't depend entirely on Javascript for validation!), it would depend on your language of choice, but you'd but checking the gender value of the request string.

you can add infinite borders using box-shadow using css3 suppose you want to apply multiple borders on one div then code is like:

div {
    border-radius: 4px;
    /* #1 */
    border: 5px solid hsl(0, 0%, 40%);
    
    /* #2 */
    padding: 5px;
    background: hsl(0, 0%, 20%);
    
    /* #3 */
    outline: 5px solid hsl(0, 0%, 60%);
    
    /* #4 AND INFINITY!!! (CSS3 only) */
    box-shadow:
        0 0 0 10px red,
        0 0 0 15px orange,
        0 0 0 20px yellow,
        0 0 0 25px green,
        0 0 0 30px blue;
}

Here's yet another way to do it.

monthToNum(shortMonth):

    return {
            'jan' : 1,
            'feb' : 2,
            'mar' : 3,
            'apr' : 4,
            'may' : 5,
            'jun' : 6,
            'jul' : 7,
            'aug' : 8,
            'sep' : 9, 
            'oct' : 10,
            'nov' : 11,
            'dec' : 12
    }[shortMonth]

First method: You could use "+" sign for concatenating strings, but this always happens in print. Another way: The String class includes a method for concatenating two strings: string1.concat(string2);

The most simple way in my opinion would be to use the PyCharm IDE and install the 'multirun' plugin. I tried alot of the solutions here but this one worked for me in the end!

If you have an async method called " RefreshList " then, you can call that async method from a non-async method like below.

Task.Run(async () => { await RefreshList(); });

You really want to do this

flog.write("\nCompany Name: "+ pCompanyName.encode('utf-8'))

This is the "encode late" strategy described in this unicode presentation (slides 32 through 35).

My case is similar but this is occasion when you have few foobar-s, and you want to close only one - per one click:

Find parent case

$(".foobar-close-button-class").on("click", function () {
    $(this).parents('.foobar').fadeOut( 100 );
    // 'this' - means that you finding some parent class from '.foobar-close-button-class'
    // '.parents' -means that you finding parent class with name '.foobar'
});

Find child case

$(".foobar-close-button-class").on("click", function () {
    $(this).child('.foobar-close-button-child-class').fadeOut( 100 );
    // 'this' - means that you finding some child class from '.foobar-close-button-class'
    // '.child' -means that you finding child class with name '.foobar-close-button-child-class'
});

Just in case anyone comes looking a solution for this problem.

The Authentication problems can be alleviated by activating the google 2-step verification for the account in use and creating an app specific password. I had the same problem as the OP. Enabling 2-step worked.

This is by far (after hours of googling and trying scripts) the simplest to set up and nicest uploader I've found

https://github.com/FineUploader/fine-uploader

It doesn't require APC or any other external PHP libraries, I can get file progress feedback on a shared host, and it claims to support html5 drag and drop (personally untested) and multiple file uploads.

If you wish to use postman the right way is to use the headers as such

key: Authorization

value: jwt {token}

as simple as that.

Your code is correct. Kindly mark small correction.

#rightcolumn {
     width: 750px;
     background-color: #777;
     display: block;
     **float: left;(wrong)**
     **float: right; (corrected)**
     border: 1px solid white;
}

In my case, Emulator: Process finished with exit code 0 error started after I pressed on Restart in the Emulator.

It happened because in Android Studio 3.0 and up versions, the emulator saves the states of the current screen to launch it very quickly at next time. So when I pressed on Restart it closes emulator by saving state as Restart. So when I launch/start the emulator, it executes the Save States as Restart and then after emulator is not started automatically. So basically it stuck in to Save States of Restart.

I don't want to delete existing emulator and create a new one.
My default Boot Option of Emulator was Quick boot in AVD.
By doing Cold Boot Now from AVD (Android Virtual Device) Manager, it starts emulator again in normal mode without Save State.

Cold boot start emulator as from power up.

you can use pdf from html as follows,

Step 1: Add the following script to the header

<script src="https://cdnjs.cloudflare.com/ajax/libs/jspdf/1.3.2/jspdf.min.js"></script>

or download locally

Step 2: Add HTML script to execute jsPDF code

Customize this to pass the identifier or just change #content to be the identifier you need.

 <script>
    function demoFromHTML() {
        var pdf = new jsPDF('p', 'pt', 'letter');
        // source can be HTML-formatted string, or a reference
        // to an actual DOM element from which the text will be scraped.
        source = $('#content')[0];

        // we support special element handlers. Register them with jQuery-style 
        // ID selector for either ID or node name. ("#iAmID", "div", "span" etc.)
        // There is no support for any other type of selectors 
        // (class, of compound) at this time.
        specialElementHandlers = {
            // element with id of "bypass" - jQuery style selector
            '#bypassme': function (element, renderer) {
                // true = "handled elsewhere, bypass text extraction"
                return true
            }
        };
        margins = {
            top: 80,
            bottom: 60,
            left: 40,
            width: 522
        };
        // all coords and widths are in jsPDF instance's declared units
        // 'inches' in this case
        pdf.fromHTML(
            source, // HTML string or DOM elem ref.
            margins.left, // x coord
            margins.top, { // y coord
                'width': margins.width, // max width of content on PDF
                'elementHandlers': specialElementHandlers
            },

            function (dispose) {
                // dispose: object with X, Y of the last line add to the PDF 
                //          this allow the insertion of new lines after html
                pdf.save('Test.pdf');
            }, margins
        );
    }
</script>

Step 3: Add your body content

<a href="javascript:demoFromHTML()" class="button">Run Code</a>
<div id="content">
    <h1>  
        We support special element handlers. Register them with jQuery-style.
    </h1>
</div>

Refer to the original tutorial

See a working fiddle

I am assuming that we are dealing with a JFrame? The visible portion in the content pane - you have to use jframe.getContentPane().setBackground(...);

Well how to find dates between two given date in SQL server is explain on http://ektaraval.blogspot.com/2010/09/writing-recursive-query-to-find-out-all.html

Yes. Pass gcc the -E option. This will output preprocessed source code.

You can call the indexer directly on the datatable variable as well:

var cellValue = dt[i].ColumnName

Using Concat on the group by will work

SELECT clients.id, clients.name, portfolios.id, SUM ( portfolios.portfolio + portfolios.cash ) AS total
FROM clients, portfolios
WHERE clients.id = portfolios.client_id
GROUP BY CONCAT(portfolios.id, "-", clients.id)
ORDER BY total DESC
LIMIT 30

Thanks to Karl Knechtel i was able to understand your question. My interpretation:

1. You want a new list with the average of the element i and i+1.
2. You want to sum each element in the list.

First question using anonymous function (aka. Lambda function):

s = lambda l: [(l[0]+l[1])/2.] + s(l[1:]) if len(l)>1 else []  #assuming you want result as float
s = lambda l: [(l[0]+l[1])//2] + s(l[1:]) if len(l)>1 else []  #assuming you want floor result

Second question also using anonymous function (aka. Lambda function):

p = lambda l: l[0] + p(l[1:]) if l!=[] else 0

Both questions combined in a single line of code :

s = lambda l: (l[0]+l[1])/2. + s(l[1:]) if len(l)>1 else 0  #assuming you want result as float
s = lambda l: (l[0]+l[1])/2. + s(l[1:]) if len(l)>1 else 0  #assuming you want floor result

use the one that fits best your needs

I achieved this by getting a result list then checking if it is empty

public boolean exist(String value) {
        List<Object> options = getEntityManager().createNamedQuery("AppUsers.findByEmail").setParameter('email', value).getResultList();
        return !options.isEmpty();
    }

It is so annoying that getSingleResult() throws exceptions

Throws:

1. NoResultException - if there is no result
2. NonUniqueResultException - if more than one result and some other exception that you can get more info on from their documentation

There is no such method as slideLeft() and slideRight() which looks like slideUp() and slideDown(), but you can simulate these effects using jQuery’s animate() function.

HTML Code:

<div class="text">Lorem ipsum.</div>

JQuery Code:

  $(document).ready(function(){
    var DivWidth = $(".text").width();
    $(".left").click(function(){
      $(".text").animate({
        width: 0
      });
    });
    $(".right").click(function(){
      $(".text").animate({
        width: DivWidth
      });
    });
  });

You can see an example here: How to slide toggle a DIV from Left to Right?

Here's the jQuery way to do it:

$('#calendar').attr('src', loc);

SELECT SUM(NULLs) AS 'NULLS', SUM(NOTNULLs) AS 'NOTNULLs' FROM 
    (select count(*) AS 'NULLs', 0 as 'NOTNULLs' FROM us WHERE a is null
    UNION select 0 as 'NULLs', count(*) AS 'NOTNULLs' FROM us WHERE a is not null) AS x

It's fugly, but it will return a single record with 2 cols indicating the count of nulls vs non nulls.

Update: capability appears to have been removed by Apple on or around iOS 4

Just to expand on an earlier answer, something like this does it for me:

NSString *num = [[NSUserDefaults standardUserDefaults] stringForKey:@"SBFormattedPhoneNumber"];

Note: This retrieves the "Phone number" that was entered during the iPhone's iTunes activation and can be null or an incorrect value. It's NOT read from the SIM card.

At least that does in 2.1. There are a couple of other interesting keys in NSUserDefaults that may also not last. (This is in my app which uses a UIWebView)

WebKitJavaScriptCanOpenWindowsAutomatically
NSInterfaceStyle
TVOutStatus
WebKitDeveloperExtrasEnabledPreferenceKey

and so on.

Not sure what, if anything, the others do.

In addition, you need the "AllowOverride Options" directive for this to work. (Apache 2.2.15)

What would happen, if you want to create many such records ones (to register 10 users, not just one)? I find the following solution (just 5 queryes):

Step I: Create temporary table to store new data.

CREATE TEMPORARY TABLE tmp (id bigint(20) NOT NULL, ...)...;

Next, fill this table with values.

INSERT INTO tmp (username, password, bio, homepage) VALUES $ALL_VAL

Here, instead of $ALL_VAL you place list of values: ('test1','test1','bio1','home1'),...,('testn','testn','bion','homen')

Step II: Send data to 'user' table.

INSERT IGNORE INTO users (username, password)
SELECT username, password FROM tmp;

Here, "IGNORE" can be used, if you allow some users already to be inside. Optionaly you can use UPDATE similar to step III, before this step, to find whom users are already inside (and mark them in tmp table). Here we suppouse, that username is declared as PRIMARY in users table.

Step III: Apply update to read all users id from users to tmp table. THIS IS ESSENTIAL STEP.

UPDATE tmp JOIN users ON tmp.username=users.username SET tmp.id=users.id

Step IV: Create another table, useing read id for users

INSERT INTO profiles (userid, bio, homepage) 
SELECT id, bio, homepage FROM tmp

some_instance.attributes

For python2 you can use this code before csv_writer.writerows(rows)
This code will NOT convert integers to utf-8 strings

def encode_rows_to_utf8(rows):
    encoded_rows = []
    for row in rows:
        encoded_row = []
        for value in row:
            if isinstance(value, basestring):
                value = unicode(value).encode("utf-8")
            encoded_row.append(value)
        encoded_rows.append(encoded_row)
    return encoded_rows

os.path.exists will also return True if there's a regular file with that name.

os.path.isdir will only return True if that path exists and is a directory, or a symbolic link to a directory.

you can also use the Array.find feature of es6. the doc is here

return restaurants.find(item => {
   return item.restaurant.food == 'chicken'
})

If you have installed using Homebrew, the below command should be enough.

brew services restart postgresql

This sometimes might not work. In that case, the below two commands should definitely work:

rm /usr/local/var/postgres/postmaster.pid

pg_ctl -D /usr/local/var/postgres start

It seems that this may be the answer you're looking for, I haven't tried this personally yet, but it seems like it may do the trick. With this command GIT will try to apply the changes as they were before, without trying to add all of them for commit.

git stash apply --index

here is the full explanation:

You need to properly decode the source text. Most likely the source text is in UTF-8 format, not ASCII.

Because you do not provide any context or code for your question it is not possible to give a direct answer.

I suggest you study how unicode and character encoding is done in Python:

http://docs.python.org/2/howto/unicode.html

def parseISO8601DateTime(datetimeStr):
    import time
    from datetime import datetime, timedelta

    def log_date_string(when):
        gmt = time.gmtime(when)
        if time.daylight and gmt[8]:
            tz = time.altzone
        else:
            tz = time.timezone
        if tz > 0:
            neg = 1
        else:
            neg = 0
            tz = -tz
        h, rem = divmod(tz, 3600)
        m, rem = divmod(rem, 60)
        if neg:
            offset = '-%02d%02d' % (h, m)
        else:
            offset = '+%02d%02d' % (h, m)

        return time.strftime('%d/%b/%Y:%H:%M:%S ', gmt) + offset

    dt = datetime.strptime(datetimeStr, '%Y-%m-%dT%H:%M:%S.%fZ')
    timestamp = dt.timestamp()
    return dt + timedelta(hours=dt.hour-time.gmtime(timestamp).tm_hour)

Note that we should look if the string doesn't ends with Z, we could parse using %z.

Although adequate answers have already been given, I'd like to propose a less verbose solution, that can be used without the helper methods available in an MVC controller class. Using a third party library called "RazorEngine" you can use .Net file IO to get the contents of the razor file and call

string html = Razor.Parse(razorViewContentString, modelObject);

Get the third party library here.

print('<tr><td>%04d</td>' % (i+1), file=Html_file)

UPDATE 2018 FOR JQUERY 3 AND LATER

I know this is an old question but none of the above solutions worked for me. Here is the solution that worked:

//I only created this function as I am making many ajax calls with different urls and appending the result to different divs
function makeAjaxCall(requestType, urlTo, resultAreaId){
        var jqxhr = $.ajax({
            type: requestType,
            url: urlTo
        });
        //this section is executed when the server responds with no error 
        jqxhr.done(function(){

        });
        //this section is executed when the server responds with error
        jqxhr.fail(function(){

        })
        //this section is always executed
        jqxhr.always(function(){
            console.log("getting header " + jqxhr.getResponseHeader('testHeader'));
        });
    }

Currently using Visual Studio Code and the command to disable tslint is

/* tslint:disable */

Something to note. The disable above disables ALL tslint rules on that page. If you want to disable a specific rule you can specify one/multiple rules.

/* tslint:disable comment-format */
/* tslint:disable:rule1 rule2 rule3 etc.. */

Or enable a rule

/* tslint:enable comment-format */

Python lists (which are not just arrays because their size can be changed on the fly) are normal Python objects and can be passed in to functions as any variable. The * syntax is used for unpacking lists, which is probably not something you want to do now.

In Oracle 11g, if you want to search any text in whole database or procedure below mentioned query can be used:

select * from user_source WHERE UPPER(text) LIKE '%YOUR SAGE%'

Modulus operator gives you the result in 'reduced residue system'. For example for mod 5 there are 5 integers counted: 0,1,2,3,4. In fact 19=12=5=-2=-9 (mod 7). The main difference that the answer is given by programming languages by 'reduced residue system'.

toggle the prompt by PROMPT command.

Usage:

ftp>cd /to/directory    
ftp>prompt    
ftp>mget  *

Method 1: Using sp_depends

 sp_depends 'dbo.First'
 GO

Method 2 : Using sys.procedures for Stored Procedures

select Name from sys.procedures where OBJECT_DEFINITION(OBJECT_ID) like '%Any Keyword Name%'

'% Any Keyword Name %' is the Search keyword you are looking for

Method 3 : Using sys.views for Views

select Name from sys.views where OBJECT_DEFINITION(OBJECT_ID) like '%Any Keyword Name%'

'% Any Keyword Name %' is the Search keyword you are looking for

This is actually a multi-step process. First you'll need to add all your files to the current stage:

git add .

You can verify that your files will be added when you commit by checking the status of the current stage:

git status

The console should display a message that lists all of the files that are currently staged, like this:

# On branch master
#
# Initial commit
#
# Changes to be committed:
#   (use "git rm --cached <file>..." to unstage)
#
#   new file:   README
#   new file:   src/somefile.js
#

If it all looks good then you're ready to commit. Note that the commit action only commits to your local repository.

git commit -m "some message goes here"

If you haven't connected your local repository to a remote one yet, you'll have to do that now. Assuming your remote repository is hosted on GitHub and named "Some-Awesome-Project", your command is going to look something like this:

git remote add origin [email protected]:username/Some-Awesome-Project

It's a bit confusing, but by convention we refer to the remote repository as 'origin' and the initial local repository as 'master'. When you're ready to push your commits to the remote repository (origin), you'll need to use the 'push' command:

git push origin master

This indicates the linux has delivered a SIGTERM to your process. This is usually at the request of some other process (via kill()) but could also be sent by your process to itself (using raise()). This signal requests an orderly shutdown of your process.

If you need a quick cheatsheet of signal numbers, open a bash shell and:

$ kill -l
 1) SIGHUP   2) SIGINT   3) SIGQUIT  4) SIGILL
 5) SIGTRAP  6) SIGABRT  7) SIGBUS   8) SIGFPE
 9) SIGKILL 10) SIGUSR1 11) SIGSEGV 12) SIGUSR2
13) SIGPIPE 14) SIGALRM 15) SIGTERM 16) SIGSTKFLT
17) SIGCHLD 18) SIGCONT 19) SIGSTOP 20) SIGTSTP
21) SIGTTIN 22) SIGTTOU 23) SIGURG  24) SIGXCPU
25) SIGXFSZ 26) SIGVTALRM   27) SIGPROF 28) SIGWINCH
29) SIGIO   30) SIGPWR  31) SIGSYS  34) SIGRTMIN
35) SIGRTMIN+1  36) SIGRTMIN+2  37) SIGRTMIN+3  38) SIGRTMIN+4
39) SIGRTMIN+5  40) SIGRTMIN+6  41) SIGRTMIN+7  42) SIGRTMIN+8
43) SIGRTMIN+9  44) SIGRTMIN+10 45) SIGRTMIN+11 46) SIGRTMIN+12
47) SIGRTMIN+13 48) SIGRTMIN+14 49) SIGRTMIN+15 50) SIGRTMAX-14
51) SIGRTMAX-13 52) SIGRTMAX-12 53) SIGRTMAX-11 54) SIGRTMAX-10
55) SIGRTMAX-9  56) SIGRTMAX-8  57) SIGRTMAX-7  58) SIGRTMAX-6
59) SIGRTMAX-5  60) SIGRTMAX-4  61) SIGRTMAX-3  62) SIGRTMAX-2
63) SIGRTMAX-1  64) SIGRTMAX    

You can determine the sender by using an appropriate signal handler like:

#include <signal.h>
#include <stdio.h>
#include <stdlib.h>

void sigterm_handler(int signal, siginfo_t *info, void *_unused)
{
  fprintf(stderr, "Received SIGTERM from process with pid = %u\n",
      info->si_pid);
  exit(0);
}

int main (void)
{
  struct sigaction action = {
    .sa_handler = NULL,
    .sa_sigaction = sigterm_handler,
    .sa_mask = 0,
    .sa_flags = SA_SIGINFO,
    .sa_restorer = NULL
  };

  sigaction(SIGTERM, &action, NULL);
  sleep(60);

  return 0;
}

Notice that the signal handler also includes a call to exit(). It's also possible for your program to continue to execute by ignoring the signal, but this isn't recommended in general (if it's a user doing it there's a good chance it will be followed by a SIGKILL if your process doesn't exit, and you lost your opportunity to do any cleanup then).

Use list.sort instead:

list.sort((o1, o2) -> o1.getItem().getValue().compareTo(o2.getItem().getValue()));

and make it more succinct using Comparator.comparing:

list.sort(Comparator.comparing(o -> o.getItem().getValue()));

After either of these, list itself will be sorted.

Your issue is that list.stream.sorted returns the sorted data, it doesn't sort in place as you're expecting.

The second question is actually easier to answer. Look at the stringWithContentsOfURL:encoding:error: method of NSString - it lets you pass in a URL as an instance of NSURL (which can easily be instantiated from NSString) and returns a string with the complete contents of the page at that URL. For example:

NSString *googleString = @"http://www.google.com";
NSURL *googleURL = [NSURL URLWithString:googleString];
NSError *error;
NSString *googlePage = [NSString stringWithContentsOfURL:googleURL 
                                                encoding:NSASCIIStringEncoding
                                                   error:&error];

After running this code, googlePage will contain the HTML for www.google.com, and error will contain any errors encountered in the fetch. (You should check the contents of error after the fetch.)

Going the other way (from a UIWebView) is a bit trickier, but is basically the same concept. You'll have to pull the request from the view, then do the fetch as before:

NSURL *requestURL = [[yourWebView request] URL];
NSError *error;
NSString *page = [NSString stringWithContentsOfURL:requestURL 
                                          encoding:NSASCIIStringEncoding
                                             error:&error];

EDIT: Both these methods take a performance hit, however, since they do the request twice. You can get around this by grabbing the content from a currently-loaded UIWebView using its stringByEvaluatingJavascriptFromString: method, as such:

NSString *html = [yourWebView stringByEvaluatingJavaScriptFromString: 
                                         @"document.body.innerHTML"];

This will grab the current HTML contents of the view using the Document Object Model, parse the JavaScript, then give it to you as an NSString* of HTML.

Another way is to do your request programmatically first, then load the UIWebView from what you requested. Let's say you take the second example above, where you have NSString *page as the result of a call to stringWithContentsOfURL:encoding:error:. You can then push that string into the web view using loadHTMLString:baseURL:, assuming you also held on to the NSURL you requested:

[yourWebView loadHTMLString:page baseURL:requestURL];

I'm not sure, however, if this will run JavaScript found in the page you load (the method name, loadHTMLString, is somewhat ambiguous, and the docs don't say much about it).

For more info:

• UIWebView class reference
• NSString class reference
• NSURL class reference

I used the same method mentioned by @S-T after the pip uninstall command. And even after that the I got the message that Django was already installed. So i deleted the 'Django-1.7.6.egg-info' folder from '/usr/lib/python2.7/dist-packages' and then it worked for me.

use a static defaultProps like:

export default class AddAddressComponent extends Component {
    static defaultProps = {
        provinceList: [],
        cityList: []
    }

render() {
   let {provinceList,cityList} = this.props
    if(cityList === undefined || provinceList === undefined){
      console.log('undefined props')
    }
    ...
}

AddAddressComponent.contextTypes = {
  router: React.PropTypes.object.isRequired
}

AddAddressComponent.defaultProps = {
  cityList: [],
  provinceList: [],
}

AddAddressComponent.propTypes = {
  userInfo: React.PropTypes.object,
  cityList: PropTypes.array.isRequired,
  provinceList: PropTypes.array.isRequired,
}

Taken from: https://github.com/facebook/react-native/issues/1772

If you wish to check the types, see how to use PropTypes in treyhakanson's or Ilan Hasanov's answer, or review the many answers in the above link.

You can do something like

git push origin +<short_commit_sha>^:<branch_name>

Make sure upload plugin implements this.each in it so that it will execute the logic for all the matching elements. It should ideally work

$("#upload_link,#upload_link2,#upload_link3").upload(function(){ });

In Juptyer notebook, a very simple way is

!pip install <package_name> --upgrade

So, you just need to replace with the actual package name.

I did some more work on these extensions - You can find the code here

I wrote some extension methods that extend System.Enum that I use often... I'm not claiming that they are bulletproof, but they have helped... Comments removed...

namespace Enum.Extensions {

    public static class EnumerationExtensions {

        public static bool Has<T>(this System.Enum type, T value) {
            try {
                return (((int)(object)type & (int)(object)value) == (int)(object)value);
            } 
            catch {
                return false;
            }
        }

        public static bool Is<T>(this System.Enum type, T value) {
            try {
                return (int)(object)type == (int)(object)value;
            }
            catch {
                return false;
            }    
        }


        public static T Add<T>(this System.Enum type, T value) {
            try {
                return (T)(object)(((int)(object)type | (int)(object)value));
            }
            catch(Exception ex) {
                throw new ArgumentException(
                    string.Format(
                        "Could not append value from enumerated type '{0}'.",
                        typeof(T).Name
                        ), ex);
            }    
        }


        public static T Remove<T>(this System.Enum type, T value) {
            try {
                return (T)(object)(((int)(object)type & ~(int)(object)value));
            }
            catch (Exception ex) {
                throw new ArgumentException(
                    string.Format(
                        "Could not remove value from enumerated type '{0}'.",
                        typeof(T).Name
                        ), ex);
            }  
        }

    }
}

Then they are used like the following

SomeType value = SomeType.Grapes;
bool isGrapes = value.Is(SomeType.Grapes); //true
bool hasGrapes = value.Has(SomeType.Grapes); //true

value = value.Add(SomeType.Oranges);
value = value.Add(SomeType.Apples);
value = value.Remove(SomeType.Grapes);

bool hasOranges = value.Has(SomeType.Oranges); //true
bool isApples = value.Is(SomeType.Apples); //false
bool hasGrapes = value.Has(SomeType.Grapes); //false

I found something from Arvind Pereira (http://robotics.usc.edu/~ampereir/wordpress/?p=626) and seemed to work for me:

plt.savefig(filename, transparent = True, bbox_inches = 'tight', pad_inches = 0)

For those interested, this is code for creating SHA-256 hash using sjcl:

import sjcl from 'sjcl'

const myString = 'Hello'
const myBitArray = sjcl.hash.sha256.hash(myString)
const myHash = sjcl.codec.hex.fromBits(myBitArray)

I had exactly the same problem. My environment was:

• Spring STS 3.7.3.RELEASE
• Build Id: 201602250940
• Platform: Eclipse Mars.2 (4.5.2)

The symptoms of the problems were:

1. There was a red error flag on my PM file. and the description of the error was as described in the original question asked here.
2. There were known compilation problems in the several Java files in the project, but eclipse still was not showing them flagged as error in the editor pane as well as the project explorer tree on the left side.

The solution (described above) about updating the m2e extensions worked for me.

Better solution (my recommondation):

• update Eclipse m2e extensions
• From Help > Install New Software.., add a new repository (via the Add.. option), pointing to the following URL: https://otto.takari.io/content/sites/m2e.extras/m2eclipse-mavenarchiver/0.17.2/N/LATEST/
• Select the m2e extensions, accept the license.
• After update, you will be asked for restarting STS. The problem goes away after STS comes back up.

Just in case anyone is interested, heres a complete Java module gradle file that correctly generates and references the built artefacts within an Android multi module application

buildscript {
    repositories {
        maven {
            url "https://plugins.gradle.org/m2/"
        }
    }
    dependencies {
        classpath "net.ltgt.gradle:gradle-apt-plugin:0.15"
    }
}

apply plugin: "net.ltgt.apt"
apply plugin: "java-library"
apply plugin: "idea"

idea {
    module {
        sourceDirs += file("$buildDir/generated/source/apt/main")
        testSourceDirs += file("$buildDir/generated/source/apt/test")
    }
}

dependencies {

    // Dagger 2 and Compiler
    compile "com.google.dagger:dagger:2.15"
    apt "com.google.dagger:dagger-compiler:2.15"
    compile "com.google.guava:guava:24.1-jre"

}

sourceCompatibility = "1.8"
targetCompatibility = "1.8"

The one liner "no imports" version

a = [0,88,26,3,48,85,65,16,97,83,91]
ind_pos = [1,5,7]
[ a[i] for i in ind_pos ]

There are several answers that cover how to solve this if you have a UNIQUE index that you can check against with ON DUPLICATE KEY or INSERT IGNORE. That is not always the case, and as UNIQUE has a length constraint (1000 bytes) you might not be able to change that. For example, I had to work with metadata in WordPress (wp_postmeta).

I finally solved it with two queries:

UPDATE wp_postmeta SET meta_value = ? WHERE meta_key = ? AND post_id = ?;
INSERT INTO wp_postmeta (post_id, meta_key, meta_value) SELECT DISTINCT ?, ?, ? FROM wp_postmeta WHERE NOT EXISTS(SELECT * FROM wp_postmeta WHERE meta_key = ? AND post_id = ?);

Query 1 is a regular UPDATE query with no effect when the dataset in question is not there. Query 2 is an INSERT which depends on a NOT EXISTS, i.e. the INSERT is only executed when the dataset doesn't exist.

Here's a method which is similar to Kelly's but will remove any pre-existing script with the same source, and uses jQuery.

<script>
    function reload_js(src) {
        $('script[src="' + src + '"]').remove();
        $('<script>').attr('src', src).appendTo('head');
    }
    reload_js('source_file.js');
</script>

Note that the 'type' attribute is no longer needed for scripts as of HTML5. (http://www.w3.org/html/wg/drafts/html/master/scripting-1.html#the-script-element)

A simpler way which eliminates checking if the app can open the url.

  loadInBrowser = () => {
    Linking.openURL(this.state.url).catch(err => console.error("Couldn't load page", err));
  };

Calling it with a button.

<Button title="Open in Browser" onPress={this.loadInBrowser} />

You can iterate over keys by calling map.keySet(), or iterate over the entries by calling map.entrySet(). Iterating over entries will probably be faster.

for (Map.Entry<String, List<String>> entry : map.entrySet()) {
    List<String> list = entry.getValue();
    // Do things with the list
}

If you want to ensure that you iterate over the keys in the same order you inserted them then use a LinkedHashMap.

By the way, I'd recommend changing the declared type of the map to <String, List<String>>. Always best to declare types in terms of the interface rather than the implementation.

To insert a single row of data:

INSERT INTO USERS
VALUES (1, 'Mike', 'Jones');

To do an insert on specific columns (as opposed to all of them) you must specify the columns you want to update.

INSERT INTO USERS (FIRST_NAME, LAST_NAME)
VALUES ('Stephen', 'Jiang');

To insert multiple rows of data in SQL Server 2008 or later:

INSERT INTO USERS VALUES
(2, 'Michael', 'Blythe'),
(3, 'Linda', 'Mitchell'),
(4, 'Jillian', 'Carson'),
(5, 'Garrett', 'Vargas');

To insert multiple rows of data in earlier versions of SQL Server, use "UNION ALL" like so:

INSERT INTO USERS (FIRST_NAME, LAST_NAME)
SELECT 'James', 'Bond' UNION ALL
SELECT 'Miss', 'Moneypenny' UNION ALL
SELECT 'Raoul', 'Silva'

Note, the "INTO" keyword is optional in INSERT queries. Source and more advanced querying can be found here.

So when sending the message to telegram you use:

$token = <Enter Your Token Here>
$url = "https://api.telegram.org/bot".$token;

$chat_id = <The Chat Id Goes Here>;
$test = <Message goes Here>;

//sending Message normally without styling
$response = file_get_content($url."\sendMessage?chat_id=$chat_id&text=$text");

If our message has html tags in it we add "parse_mode" so that our url becomes:

$response = file_get_content($url."\sendMessage?chat_id=$chat_id&text=$text&parse_mode=html")

parse mode can be "HTML" or "markdown"

You can also open a required file through a prompt, This helps when you want to select file from different path and different file.

Sub openwb()
Dim wkbk As Workbook
Dim NewFile As Variant

NewFile = Application.GetOpenFilename("microsoft excel files (*.xlsm*), *.xlsm*")

If NewFile <> False Then
Set wkbk = Workbooks.Open(NewFile)
End If
End Sub

The best way to handle the LazyInitializationException is to fetch it upon query time, like this:

select t
from Topic t
left join fetch t.comments

You should ALWAYS avoid the following anti-patterns:

• FetchType.EAGER
• OSIV (Open Session in View)
• hibernate.enable_lazy_load_no_trans Hibernate configuration property

Therefore, make sure that your FetchType.LAZY associations are initialized at query time or within the original @Transactional scope using Hibernate.initialize for secondary collections.

Since JDK 1.7, the canonical way to have an application be notified of changes to a file is using the WatchService API. The WatchService is event-driven. The official tutorial provides an example:

For individual files, various solutions exist, such as:

• https://dzone.com/articles/listening-to-fileevents-with-java-nio

Note that Apache VFS uses a polling algorithm, although it may offer greater functionality. Also note that the API does not offer a way to determine whether a file has been closed.

PyCharm 4 now has virtualenvs integrated in the IDE. When selecting your project interpreter, you can create, add, or select a virtualenv. They've added a "Python Console" that runs in the configured project interpreter.

More info here.

If you would like to see more how this work with a live example. http://jsfiddle.net/juanmendez/k6chmnch/

var app = angular.module('app', []);
app.controller("myController", function ($scope) {
    $scope.title = "binding";
});
app.directive("jmFind", function () {
    return {
        replace: true,
        restrict: 'C',
        transclude: true,
        scope: {
            title1: "=",
            title2: "@"
        },
        template: "<div><p>{{title1}} {{title2}}</p></div>"

We'll check a Collection object is empty, null or not. these all methods which are given below, are present in org.apache.commons.collections4.CollectionUtils package.

Check on List or set type of collection Objects.

CollectionUtils.isEmpty(listObject);
CollectionUtils.isNotEmpty(listObject);

Check on Map type of Objects.

MapUtils.isEmpty(mapObject);
MapUtils.isNotEmpty(mapObject);

The return type of all methods is boolean.

You can use operator.itemgetter for that:

import operator
stats = {'a':1000, 'b':3000, 'c': 100}
max(stats.iteritems(), key=operator.itemgetter(1))[0]

And instead of building a new list in memory use stats.iteritems(). The key parameter to the max() function is a function that computes a key that is used to determine how to rank items.

Please note that if you were to have another key-value pair 'd': 3000 that this method will only return one of the two even though they both have the maximum value.

>>> import operator
>>> stats = {'a':1000, 'b':3000, 'c': 100, 'd':3000}
>>> max(stats.iteritems(), key=operator.itemgetter(1))[0]
'b' 

If using Python3:

>>> max(stats.items(), key=operator.itemgetter(1))[0]
'b'

This works for me,this method will SFTP a file to a location within your network. It uses SSH.NET.2013.4.7 library.One can just download it for free.

    //Secure FTP
    public void SecureFTPUploadFile(string destinationHost,int port,string username,string password,string source,string destination)

    {
        ConnectionInfo ConnNfo = new ConnectionInfo(destinationHost, port, username, new PasswordAuthenticationMethod(username, password));

        var temp = destination.Split('/');
        string destinationFileName = temp[temp.Count() - 1];
        string parentDirectory = destination.Remove(destination.Length - (destinationFileName.Length + 1), destinationFileName.Length + 1);


        using (var sshclient = new SshClient(ConnNfo))
        {
            sshclient.Connect();
            using (var cmd = sshclient.CreateCommand("mkdir -p " + parentDirectory + " && chmod +rw " + parentDirectory))
            {
                cmd.Execute();
            }
            sshclient.Disconnect();
        }


        using (var sftp = new SftpClient(ConnNfo))
        {
            sftp.Connect();
            sftp.ChangeDirectory(parentDirectory);
            using (var uplfileStream = System.IO.File.OpenRead(source))
            {
                sftp.UploadFile(uplfileStream, destinationFileName, true);
            }
            sftp.Disconnect();
        }
    }

just write it yourself using simple recursion:

public List<File> addFiles(List<File> files, File dir)
{
    if (files == null)
        files = new LinkedList<File>();

    if (!dir.isDirectory())
    {
        files.add(dir);
        return files;
    }

    for (File file : dir.listFiles())
        addFiles(files, file);
    return files;
}

Found a way to find the current route name works for laravel v5 , v5.1.28 and v5.2.10

Namespace

use Illuminate\Support\Facades\Route;

and

$currentPath= Route::getFacadeRoot()->current()->uri();

For Laravel laravel v5.3 you can just use:

use Illuminate\Support\Facades\Route;

Route::currentRouteName();

In C++, variable length arrays are not legal. G++ allows this as an "extension" (because C allows it), so in G++ (without being -pedantic about following the C++ standard), you can do:

int n = 10;
double a[n]; // Legal in g++ (with extensions), illegal in proper C++

If you want a "variable length array" (better called a "dynamically sized array" in C++, since proper variable length arrays aren't allowed), you either have to dynamically allocate memory yourself:

int n = 10;
double* a = new double[n]; // Don't forget to delete [] a; when you're done!

Or, better yet, use a standard container:

int n = 10;
std::vector<double> a(n); // Don't forget to #include <vector>

If you still want a proper array, you can use a constant, not a variable, when creating it:

const int n = 10;
double a[n]; // now valid, since n isn't a variable (it's a compile time constant)

Similarly, if you want to get the size from a function in C++11, you can use a constexpr:

constexpr int n()
{
    return 10;
}

double a[n()]; // n() is a compile time constant expression

The problem could be that we need to specifically give adb root access in the developnent options in the latest CMs.. Here is what i did.

abc@abc-L655:~$ sudo adb kill-server
abc@abc-L655:~$ sudo adb root start-server * daemon not running. starting it now on port 5037 * * daemon started successfully * root access is disabled by system setting - enable in settings -> development options

after altering the development options...

abc@abc-L655:~$ sudo adb kill-server
abc@abc-L655:~$ sudo adb root start-server
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
restarting adbd as root
abc@abc-L655:~$ adb shell
root@android:/ # ls /data/ .... good to go.. 

You probably need something like:

result.className = 'red'; 

In pure JavaScript you should use className to deal with classes. jQuery has an abstraction called addClass for it.

For Word 2010 and 2013, go to File > Options > Customize Ribbon > Keyboard Shortcuts > All Commands (in left list) > Color: (in right list) -- at this point, you type in the short cut (such as Alt+r) and select the color (such as red). (This actually goes back to 2003 but I don't have that installed to provide the pathway.)

Named aggregations with pandas >= 0.25.0

Since pandas version 0.25.0 we have named aggregations where we can groupby, aggregate and at the same time assign new names to our columns. This way we won't get the MultiIndex columns, and the column names make more sense given the data they contain:

aggregate and get a list of strings

grp = df.groupby('A').agg(B_sum=('B','sum'),
                          C=('C', list)).reset_index()

print(grp)
   A     B_sum               C
0  1  1.615586  [This, string]
1  2  0.421821         [is, !]
2  3  0.463468             [a]
3  4  0.643961        [random]

aggregate and join the strings

grp = df.groupby('A').agg(B_sum=('B','sum'),
                          C=('C', ', '.join)).reset_index()

print(grp)
   A     B_sum             C
0  1  1.615586  This, string
1  2  0.421821         is, !
2  3  0.463468             a
3  4  0.643961        random

If you ever have a choice between a reflective solution and a non-reflective solution, never pick the reflective one (involving Class objects). It's not that it's "Wrong" or anything, but anything involving reflection is generally less obvious and less clear.

I try

rm ~/.ssh/id_rsa.pub

then it work!

SHOW TABLES LIKE 'TableName'

If you have ANY results, the table exists.

To use this approach in PDO:

$pdo         = new \PDO(/*...*/);
$result      = $pdo->query("SHOW TABLES LIKE 'tableName'");
$tableExists = $result !== false && $result->rowCount() > 0;

To use this approach with DEPRECATED mysql_query

$result      = mysql_query("SHOW TABLES LIKE 'tableName'");
$tableExists = mysql_num_rows($result) > 0;

These are my solutions for paging the result of query in SQL server side. these approaches are different between SQL Server 2008 and 2012. Also, I have added the concept of filtering and order by with one column. It is very efficient when you are paging and filtering and ordering in your Gridview.

Before testing, you have to create one sample table and insert some row in this table : (In real world you have to change Where clause considering your table fields and maybe you have some join and subquery in main part of select)

Create Table VLT
(
    ID int IDentity(1,1),
    Name nvarchar(50),
    Tel Varchar(20)
)
GO


Insert INTO VLT
VALUES
    ('NAME' + Convert(varchar(10),@@identity),'FAMIL' + Convert(varchar(10),@@identity))
GO 500000

In all of these sample, I want to query 200 rows per page and I am fetching the row for page number 1200.

In SQL server 2008, you can use the CTE concept. Because of that, I have written two type of query for SQL server 2008+

DECLARE @FilterValue nvarchar(255) = '' --The value the user gave for the filter
DECLARE @FilterColumn int = 1 --The column to wich the filter is applied, represents the column number like when we send the information.

The easiest way is just a link tag:

<link rel="image_src" href="http://stackoverflow.com/images/logo.gif" />

But there are some other things you can add to your site to make it more Social media friendly:

Open Graph Tags

Open Graph tags are tags that you add to the <head> of your website to describe the entity your page represents, whether it is a band, restaurant, blog, or something else.

An Open Graph tag looks like this:

<meta property="og:tag name" content="tag value"/> 

If you use Open Graph tags, the following six are required:

• og:title - The title of the entity.
• og:type - The type of entity. You must select a type from the list of Open Graph types.
• og:image - The URL to an image that represents the entity. Images must be at least 50 pixels by 50 pixels. Square images work best, but you are allowed to use images up to three times as wide as they are tall.
• og:url - The canonical, permanent URL of the page representing the entity. When you use Open Graph tags, the Like button posts a link to the og:url instead of the URL in the Like button code.
• og:site_name - A human-readable name for your site, e.g., "IMDb".
• fb:admins or fb:app_id - A comma-separated list of either the Facebook IDs of page administrators or a Facebook Platform application ID. At a minimum, include only your own Facebook ID.

More information on Open Graph tags and details on Administering your page can be found on the Open Graph protocol documentation.

http://developers.facebook.com/docs/reference/plugins/like

You shouldn't use ${varName} when you're outside of strings, you should just use varName. Inside strings you use it like this; echo "this is a string ${someVariable}";. Infact you can place an general java expression inside of ${...}; echo "this is a string ${func(arg1, arg2)}.

I know the Q is not about Firefox but I did not want to add a copy of this question to just answer it myself.

For Firefox you need to add debugger; to be able to do what @matt-ball suggested for the script tag.

So on your code, you add debugger above the line you want to debug and then you can add breakpoints. If you just set the breakpoints on the browser it won't stop.

If this is not the place to add a Firefox answer given that the question is about Chrome. Don't :( minus the answer just let me know where I should post it and I'll happily move the post. :)

You can follow below steps to resolve this error:

Step 1

Open terminal

Step 2

cd node_modules/react-native/third-party

Step 3

ls

Copy or identify glog-{version}

Step 4

cd ../../../

Step 5

cd node_modules/react-native/third-party/glog-{version}

Step 6

./configure

I hope this will work !!!

TRANSLATE (column_name, 'd'||CHR(10)||CHR(13), 'd')

The 'd' is a dummy character, because translate does not work if the 3rd parameter is null.

I faced same issue apply all possible solution but finally this solve my problem

export class AppRoutingModule {
constructor(private router: Router) {
    this.router.errorHandler = (error: any) => {
        this.router.navigate(['404']); // or redirect to default route
    }
  }
}

Hope this will help you.

In my case, I need to set the path of openssl.cnf file manually on the command using config option. So the command

openssl req -x509 -config "C:\Users\sk\Downloads\openssl-0.9.8k_X64\openssl.cnf" -newkey rsa:4096 -keyout key.pem -out cert.pem -nodes -days 900

The DragListView lib does this really neat with very nice support for custom animations such as elevation animations. It is also still maintained and updated on a regular basis.

Here is how you use it:

1: Add the lib to gradle first

dependencies {
    compile 'com.github.woxthebox:draglistview:1.2.1'
}

2: Add list from xml

<com.woxthebox.draglistview.DragListView
    android:id="@+id/draglistview"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

3: Set the drag listener

mDragListView.setDragListListener(new DragListView.DragListListener() {
    @Override
    public void onItemDragStarted(int position) {
    }

    @Override
    public void onItemDragEnded(int fromPosition, int toPosition) {
    }
});

4: Create an adapter overridden from DragItemAdapter

public class ItemAdapter extends DragItemAdapter<Pair<Long, String>, ItemAdapter.ViewHolder>
    public ItemAdapter(ArrayList<Pair<Long, String>> list, int layoutId, int grabHandleId, boolean dragOnLongPress) {
        super(dragOnLongPress);
        mLayoutId = layoutId;
        mGrabHandleId = grabHandleId;
        setHasStableIds(true);
        setItemList(list);
}

5: Implement a viewholder that extends from DragItemAdapter.ViewHolder

public class ViewHolder extends DragItemAdapter.ViewHolder {
    public TextView mText;

    public ViewHolder(final View itemView) {
        super(itemView, mGrabHandleId);
        mText = (TextView) itemView.findViewById(R.id.text);
    }

    @Override
    public void onItemClicked(View view) {
    }

    @Override
    public boolean onItemLongClicked(View view) {
        return true;
    }
}

It's 2³¹ − 1 (32 bits, one is used for sign).

If you want an approximate value, use 2¹⁰ = 1024 ≈ 10³, so 2³¹ ≈ 2*10⁹. If you want to compute an exact value by hand, use exponentiation by squaring to get to 2³² = 2⁽²⁵⁾ and divide by two. You only need to square five times to get 2³²:

2*2 = 4
4*4 = 16
16*16 = 256
256*256 = 25*25*100 + 2*250*6 + 36 = 62500 + 3000 + 36 = 65536
65536*65536 =65000*65000 + 2*65000*536 + 536*536 =  
4225000000 + 130000*536 + (250000 + 3600 + 36*36) =
4225000000 + 69680000 + 250000 + 3600 + 1296 =
4294967296

dividing this by two and subtracting one gives you 2,147,483,647. If you don't need all digits, but only want say, the first three significant digits, the computations on each squaring step are very easy.

Swift version:

If you are in a Navigation Controller:

let viewController: ViewController = self.storyboard?.instantiateViewControllerWithIdentifier("VC") as ViewController
self.navigationController?.pushViewController(viewController, animated: true)

Or if you just want to present a new view:

let viewController: ViewController = self.storyboard?.instantiateViewControllerWithIdentifier("VC") as ViewController
self.presentViewController(viewController, animated: true, completion: nil)

Check out the Programmatically Displaying the Settings Page

    startActivity(context, new Intent(Settings.ACTION_SETTINGS), /*options:*/ null);

In general, you use the predefined constant Settings.ACTION__SETTINGS. The full list can be found here

You can do (jQuery 1.6 onwards):

$('#idCheckbox').prop('checked', true);
$('#idCheckbox').prop('checked', false);

to remove you can also use:

$('#idCheckbox').removeProp('checked');

with jQuery < 1.6 you must do

$('#idCheckbox').attr('checked', true);
$('#idCheckbox').removeAttr('checked');

To use the array type properly as a function argument or template parameter, make a struct instead of a typedef, then add an operator[] to the struct so you can keep the array like functionality like so:

typedef struct type24 {
  char& operator[](int i) { return byte[i]; }
  char byte[3];
} type24;

type24 x;
x[2] = 'r';
char c = x[2];

If you want the year of any date object, I used the following method:

public static int getYearFromDate(Date date) {
    int result = -1;
    if (date != null) {
        Calendar cal = Calendar.getInstance();
        cal.setTime(date);
        result = cal.get(Calendar.YEAR);
    }
    return result;
}

Yes, I also found it here: http://developer.android.com/tools/testing/activity_testing.html It's seems a key-input protection mechanism which includes the screen-lock, but not only includes it. According to this webpage, it also defines some key-input restriction for auto-test framework in Android.

java.exe is the console app while javaw.exe is windows app (console-less). You can't have Console with javaw.exe.

Another alternative would be to set environment variable ANDROID_SERIAL to the relevant serial, here assuming you are using Windows:

set ANDROID_SERIAL=7f1c864e
echo %ANDROID_SERIAL%
"7f1c864e"

Then you can use adb.exe shell without any issues.

Query to find out all the datatype of columns being used in any database

SELECT distinct DATA_TYPE FROM INFORMATION_SCHEMA.columns 
WHERE table_schema = '<db_name>' AND column_name like '%';

You could open a command prompt, CD to the Debug or Release folder, and type the name of your exe. When I suggest this to people they think it is a lot of work, but here are the bare minimum clicks and keystrokes for this:

• in Visual Studio, right click your project in Solution Explorer or the tab with the file name if you have a file in the solution open, and choose Open Containing Folder or Open in Windows Explorer
• in the resulting Windows Explorer window, double-click your way to the folder with the exe
• Shift-right-click in the background of the explorer window and choose Open Commmand Window here
• type the first letter of your executable and press tab until the full name appears
• press enter

I think that's 14 keystrokes and clicks (counting shift-right-click as two for example) which really isn't much. Once you have the command prompt, of course, running it again is just up-arrow, enter.

Embed code example:

<object type="application/pdf" data="example.pdf" width="100%" height="100%" id="examplePDF" name="examplePDF"><param name='src' value='example.pdf'/></object>

<script>
   examplePDF.printWithDialog();
</script>

May have to fool around with the ids/names. Using adobe reader...

I know it's not exactly what you are looking for, but maybe it'll help you.

You can try use a jQuery selector :contains(), add a class and then do a normal style for a class.

I did it by passing the cookie through the HttpContext:

HttpContext localContext = new BasicHttpContext();

localContext.setAttribute(ClientContext.COOKIE_STORE, cookieStore);

response = client.execute(httppost, localContext);

In Jackson 2.x, use:

Here is a tutorial to export files as ZIP:

Before getting started, there is a library to save files, the name of library is fileSaver.js, You can find this library here. Let's get started, Now, include the required libraries:

<script src="https://cdnjs.cloudflare.com/ajax/libs/jszip/3.1.4/jszip.min.js"  type="text/javascript"></script>
<script type="text/javascript" src="https://fastcdn.org/FileSaver.js/1.1.20151003/FileSaver.js" ></script>

Now copy this code and this code will download a zip file with a file hello.txt having content Hello World. If everything thing works fine, this will download a file.

<script type="text/javascript">
    var zip = new JSZip();
    zip.file("Hello.txt", "Hello World\n");
    zip.generateAsync({type:"blob"})
    .then(function(content) {
        // see FileSaver.js
        saveAs(content, "file.zip");
    });
</script>

This will download a file called file.zip. You can read more here: http://www.wapgee.com/story/248/guide-to-create-zip-files-using-javascript-by-using-jszip-library

I was facing the same problem. After a lot of alternatives what I did was just reset the embed src="" with the same URL.

Code snippet:

  $("#videocontainer").fadeOut(200);<br/>
  $("#videoplayer").attr("src",videoURL);

I was able to at least stop the video from playing when I hide it.:-)

I haven't tried using Lombok yet - it is/was next on my list, but it sounds as if Java 8 has caused significant problems for it, and remedial work was still in progress as of a week ago. My source for that is https://code.google.com/p/projectlombok/issues/detail?id=451 .

It's a hex number and is 16 decimal.

I found it very useful to encode my URL to a safe one when I was returning a value through Ajax/PHP to a URL which was then read by the page again.

PHP output with URL encoder for the special character &:

// PHP returning the success information of an Ajax request
echo "".str_replace('&', '%26', $_POST['name']) . " category was changed";

// JavaScript sending the value to the URL
window.location.href = 'time.php?return=updated&val=' + msg;

// JavaScript/PHP executing the function printing the value of the URL,
// now with the text normally lost in space because of the reserved & character.

setTimeout("infoApp('updated','<?php echo $_GET['val'];?>');", 360);

I suppose you want to publish and access your applications/websites from LAN; probably as virtual directories under the default website.The steps could vary depending on your IIS version, but basically it comes down to these steps:

Restore your "Default Website" Website :

1. create a new website

2. set "Default Website" as its name

3. In the Binding section (bottom panel), enter your local IP address in the "IP Address" edit.

4. Keep the "Host" edit empty

that's it: now whenever you type your local ip address in your browser, you will get the website you just added. Now if you want to access any of your other webapplications/websites from LAN, just add a virtual application under your default website pointing to the directory containing your published application/website. Now you can type : http://yourLocalIPAddress/theNameOfYourApplication to access it from your LAN.

According to user m9dhatter on LinuxQuestions.org:

"make" uses the time stamp of the file to determine if the file it is trying to compile is old or new. if your clock is bonked, it may have problems compiling.

if you try to modify files at another machine with a clock time ahead by a few minutes and transfer them to your machine and then try to compile it may cough up a warning that says the file was modified from the future. clock may be skewed or something to that effect ( cant really remember ). you could just ls to the offending file and do this:

#touch <filename of offending file>

As seen on WWDC 2016/XCode 8 (what's new in LLVM session @5:05). Class properties can be declared as follows

@interface MyType : NSObject
@property (class) NSString *someString;
@end

NSLog(@"format string %@", MyType.someString);

Note that class properties are never synthesized

@implementation
static NSString * _someString;
+ (NSString *)someString { return _someString; }
+ (void)setSomeString:(NSString *)newString { _someString = newString; }
@end

There is an 'exceptions' window in VS2005 ... try Ctrl+Alt+E when debugging and click on the 'Thrown' checkbox for the exception you want to stop on.

public ActionResult SomeAction(string start, string end)

The framework will map the query string parameters to the method parameters.

You can simply put javascript expression in ng-model.

When a script is loaded, any parameters that are passed are automatically loaded into a special variables $args. You can reference that in your script without first declaring it.

As an example, create a file called test.ps1 and simply have the variable $args on a line by itself. Invoking the script like this, generates the following output:

PowerShell.exe -File test.ps1 a b c "Easy as one, two, three"
a
b
c
Easy as one, two, three

As a general recommendation, when invoking a script by calling PowerShell directly I would suggest using the -File option rather than implicitly invoking it with the & - it can make the command line a bit cleaner, particularly if you need to deal with nested quotes.

Turn if off:

You can use error_reporting(); or put an @ in front of your fileopen().

If you're using Microsoft's C++ compiler, then you could do the following:

struct __declspec(novtable) IFoo
{
    virtual void Bar() = 0;
};

class Child : public IFoo
{
public:
    virtual void Bar() override { /* Do Something */ }
}

I like this approach because it results in a lot smaller interface code and the generated code size can be significantly smaller. The use of novtable removes all reference to the vtable pointer in that class, so you can never instantiate it directly. See the documentation here - novtable.

I also ran into problems this morning with users being able to enter non-integer responses to my specific request for an integer.

This was the solution that ended up working well for me to force an answer I wanted:

player_number = 0
while player_number != 1 and player_number !=2:
    player_number = raw_input("Are you Player 1 or 2? ")
    try:
        player_number = int(player_number)
    except ValueError:
        print "Please enter '1' or '2'..."

I would get exceptions before even reaching the try: statement when I used

player_number = int(raw_input("Are you Player 1 or 2? ") 

and the user entered "J" or any other non-integer character. It worked out best to take it as raw input, check to see if that raw input could be converted to an integer, and then convert it afterward.

Absolutely valid.

    <form action="javascript:alert('Hello there, I am being submitted');">
        <button type="submit">
            Let's do it
        </button>
    </form>
    <!-- Tested in Firefox, Chrome, Edge and Safari -->

So for a short answer: yes, this is an option, and a nice one. It says "when submitted, please don't go anywhere, just run this script" - quite to the point.

A minor improvement

To let the event handler know which form we're dealing with, it would seem an obvious way to pass on the sender object:

    <form action="javascript:myFunction(this)">  <!-- should work, but it won't -->

But instead, it will give you undefined. You can't access it because javascript: links live in a separate scope. Therefore I'd suggest the following format, it's only 13 characters more and works like a charm:

    <form action="javascript:;" onsubmit="myFunction(this)">  <!-- now you have it! -->

... now you can access the sender form properly. (You can write a simple "#" as action, it's quite common - but it has a side effect of scrolling to the top when submitting.)

Again, I like this approach because it's effortless and self-explaining. No "return false", no jQuery/domReady, no heavy weapons. It just does what it seems to do. Surely other methods work too, but for me, this is The Way Of The Samurai.

A note on validation

Forms only get submitted if their onsubmit event handler returns something truthy, so you can easily run some preemptive checks:

    <form action="/something.php" onsubmit="return isMyFormValid(this)">

Now isMyFormValid will run first, and if it returns false, server won't even be bothered. Needless to say, you will have to validate on server side too, and that's the more important one. But for quick and convenient early detection this is fine.

My variant: stored procedure that takes table name, field names and delimiter as arguments. Inspired by post http://www.marcogoncalves.com/2011/03/mysql-split-column-string-into-rows/

delimiter $$

DROP PROCEDURE IF EXISTS split_value_into_multiple_rows $$
CREATE PROCEDURE split_value_into_multiple_rows(tablename VARCHAR(20),
    id_column VARCHAR(20), value_column VARCHAR(20), delim CHAR(1))
  BEGIN
    DECLARE id INT DEFAULT 0;
    DECLARE value VARCHAR(255);
    DECLARE occurrences INT DEFAULT 0;
    DECLARE i INT DEFAULT 0;
    DECLARE splitted_value VARCHAR(255);
    DECLARE done INT DEFAULT 0;

    DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = 1;

    SET @expr = CONCAT('CREATE TEMPORARY TABLE tmp_table1 (id INT NOT NULL, value VARCHAR(255)) ENGINE=Memory SELECT ',
        id_column,' id, ', value_column,' value FROM ',tablename);

        FETCH cur INTO id, value;

        WHILE i <= occurrences DO
          SET splitted_value = (SELECT TRIM(SUBSTRING_INDEX(
              SUBSTRING_INDEX(value, delim, i), delim, -1)));

Usage example (normalization):

CALL split_value_into_multiple_rows('my_contacts', 'contact_id', 'interests', ',');

CREATE TABLE interests (
  interest_id INT NOT NULL AUTO_INCREMENT PRIMARY KEY,
  interest VARCHAR(30) NOT NULL
) SELECT DISTINCT value interest FROM tmp_table2;

CREATE TABLE contact_interest (
  contact_id INT NOT NULL,
  interest_id INT NOT NULL,
  CONSTRAINT fk_contact_interest_my_contacts_contact_id FOREIGN KEY (contact_id) REFERENCES my_contacts (contact_id),
  CONSTRAINT fk_contact_interest_interests_interest_id FOREIGN KEY (interest_id) REFERENCES interests (interest_id)
) SELECT my_contacts.contact_id, interests.interest_id
    FROM my_contacts, tmp_table2, interests
    WHERE my_contacts.contact_id = tmp_table2.id AND interests.interest = tmp_table2.value;

Use the affix component included with Bootstrap. Start with a 'navbar-static-top' and this will change it to fixed when the height of your header (content above the navbar) is reached...

$('#nav').affix({
      offset: {
        top: $('header').height()
      }
});

My solution to this issue was that my old laptop was taking wayyyyyyyyyyy too long to start up. I opened Virtual Box, connected to the box and waited for the screen to load. Took about 8 minutes.

Then it connected and mounted my folders and went ahead.

just be patient sometimes!

The scope <scope>provided</scope> gives you an opportunity to tell that the jar would be available at runtime, so do not bundle it. It does not mean that you do not need it at compile time, hence maven would try to download that.

Now I think, the below maven artifact do not exist at all. I tries searching google, but not able to find. Hence you are getting this issue.

Change groupId to <groupId>net.sourceforge.ant4x</groupId> to get the latest jar.

<dependency>
  <groupId>net.sourceforge.ant4x</groupId>
  <artifactId>ant4x</artifactId>
  <version>${net.sourceforge.ant4x-version}</version>
  <scope>provided</scope>
</dependency>

Another solution for this problem is:

1. Run your own maven repo.
2. download the jar
3. Install the jar into the repository.
4. Add a code in your pom.xml something like:

Where http://localhost/repo is your local repo URL:

<repositories>
    <repository>
        <id>wmc-central</id>
        <url>http://localhost/repo</url>
    </repository>
    <-- Other repository config ... -->
</repositories>

No it is not possible. The only way that is possible is

static void Main(string[] args)
{
    BaseClass myBaseObject = new DerivedClass();
    DerivedClass myDerivedObject = myBaseObject as DerivedClass;

    myDerivedObject.MyDerivedProperty = true;
}

Just additional notes. Using class ES6, When we create static methods..the Javacsript engine set the descriptor attribute a lil bit different from the old-school "static" method

function Car() {

}

Car.brand = function() {
  console.log('Honda');
}

console.log(
  Object.getOwnPropertyDescriptors(Car)
);

it sets internal attribute (descriptor property) for brand() to

..
brand: [object Object] {
    configurable: true,
    enumerable: true,
    value: ..
    writable: true

}
..

compared to

class Car2 {
   static brand() {
     console.log('Honda');
   }
}

console.log(
  Object.getOwnPropertyDescriptors(Car2)
);

that sets internal attribute for brand() to

..
brand: [object Object] {
    configurable: true,
    enumerable: false,
    value:..
    writable: true
  }

..

see that enumerable is set to false for static method in ES6.

it means you cant use the for-in loop to check the object

for (let prop in Car) {
  console.log(prop); // brand
}

for (let prop in Car2) {
  console.log(prop); // nothing here
}

static method in ES6 is treated like other's class private property (name, length, constructor) except that static method is still writable thus the descriptor writable is set to true { writable: true }. it also means that we can override it

Car2.brand = function() {
   console.log('Toyota');
};

console.log(
  Car2.brand() // is now changed to toyota
);

Try the following:

$ch = curl_init("http://www.example-webpage.com/file.html");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_BINARYTRANSFER, true);
$content = curl_exec($ch);
curl_close($ch);

I would only recommend this for small files. Big files are read as a whole and are likely to produce a memory error.

EDIT: after some discussion in the comments we found out that the problem was that the server couldn't resolve the host name and the page was in addition a HTTPS resource so here comes your temporary solution (until your server admin fixes the name resolving).

what i did is just pinging graph.facebook.com to see the IP address, replace the host name with the IP address and instead specify the header manually. This however renders the SSL certificate invalid so we have to suppress peer verification.

//$url = "https://graph.facebook.com/19165649929?fields=name";
$url = "https://66.220.146.224/19165649929?fields=name";
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_BINARYTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Host: graph.facebook.com'));
$output = curl_exec($ch);
curl_close($ch); 

Keep in mind that the IP address might change and this is an error source. you should also do some error handling using curl_error();.

Background

You can use the base64 CLI tool to generate the base64 encoded version of your username + password like this:

$ echo -n "joeuser:secretpass" | base64
am9ldXNlcjpzZWNyZXRwYXNz

-or-

$ base64 <<<"joeuser:secretpass"
am9ldXNlcjpzZWNyZXRwYXNzCg==

Base64 is reversible so you can also decode it to confirm like this:

$ echo -n "joeuser:secretpass" | base64 | base64 -D
joeuser:secretpass

-or-

$ base64 <<<"joeuser:secretpass" | base64 -D
joeuser:secretpass

NOTE: username = joeuser, password = secretpass

Example #1 - using -H

You can put this together into curl like this:

$ curl -H "Authorization: Basic $(base64 <<<"joeuser:secretpass")" http://example.com

Example #2 - using -u

Most will likely agree that if you're going to bother doing this, then you might as well just use curl's -u option.

$ curl --help |grep -- "--user "
 -u, --user USER[:PASSWORD]  Server user and password

For example:

$ curl -u someuser:secretpass http://example.com

But you can do this in a semi-safer manner if you keep your credentials in a encrypted vault service such as LastPass or Pass.

For example, here I'm using the LastPass' CLI tool, lpass, to retrieve my credentials:

$ curl -u $(lpass show --username example.com):$(lpass show --password example.com) \
     http://example.com

Example #3 - using curl config

There's an even safer way to hand your credentials off to curl though. This method makes use of the -K switch.

$ curl -X GET -K \
    <(cat <<<"user = \"$(lpass show --username example.com):$(lpass show --password example.com)\"") \
    http://example.com

When used, your details remain hidden, since they're passed to curl via a temporary file descriptor, for example:

+ curl -skK /dev/fd/63 -XGET -H 'Content-Type: application/json' https://es-data-01a.example.com:9200/_cat/health
++ cat
+++ lpass show --username example.com
+++ lpass show --password example.com
1561075296 00:01:36 rdu-es-01 green 9 6 2171 1085 0 0 0 0 - 100.0%       

NOTE: Above I'm communicating with one of our Elasticsearch nodes, inquiring about the cluster's health.

This method is dynamically creating a file with the contents user = "<username>:<password>" and giving that to curl.

HTTP Basic Authorization

The methods shown above are facilitating a feature known as Basic Authorization that's part of the HTTP standard.

When the user agent wants to send authentication credentials to the server, it may use the Authorization field.

The Authorization field is constructed as follows:

1. The username and password are combined with a single colon (:). This means that the username itself cannot contain a colon.
2. The resulting string is encoded into an octet sequence. The character set to use for this encoding is by default unspecified, as long as it is compatible with US-ASCII, but the server may suggest use of UTF-8 by sending the charset parameter.
3. The resulting string is encoded using a variant of Base64.
4. The authorization method and a space (e.g. "Basic ") is then prepended to the encoded string.

For example, if the browser uses Aladdin as the username and OpenSesame as the password, then the field's value is the base64-encoding of Aladdin:OpenSesame, or QWxhZGRpbjpPcGVuU2VzYW1l. Then the Authorization header will appear as:

Authorization: Basic QWxhZGRpbjpPcGVuU2VzYW1l

Source: Basic access authentication

For anyone that this might be handy for, here is a jQuery dependent function I had success with for applying a CSS animation via a CSS class, then getting a callback from afterwards. It may not work perfectly since I had it being used in a Backbone.js App, but maybe useful.

var cssAnimate = function(cssClass, callback) {
    var self = this;

    // Checks if correct animation has ended
    var setAnimationListener = function() {
        self.one(
            "webkitAnimationEnd oanimationend msAnimationEnd animationend",
            function(e) {
                if(
                    e.originalEvent.animationName == cssClass &&
                    e.target === e.currentTarget
                ) {
                    callback();
                } else {
                    setAnimationListener();
                }
            }
        );
    }

    self.addClass(cssClass);
    setAnimationListener();
}

I used it kinda like this

cssAnimate.call($("#something"), "fadeIn", function() {
    console.log("Animation is complete");
    // Remove animation class name?
});

Original idea from http://mikefowler.me/2013/11/18/page-transitions-in-backbone/

And this seems handy: http://api.jqueryui.com/addClass/

Update

After struggling with the above code and other options, I would suggest being very cautious with any listening for CSS animation ends. With multiple animations going on, this can get messy very fast for event listening. I would strongly suggest an animation library like GSAP for every animation, even the small ones.
