Since AngularJS 1.5 we should use $onInit which is available on any AngularJS component. Taken from the component lifecycle documentation since v1.5 its the preffered way:

$onInit() - Called on each controller after all the controllers on an element have been constructed and had their bindings initialized (and before the pre & post linking functions for the directives on this element). This is a good place to put initialization code for your controller.

var myApp = angular.module('myApp',[]);
myApp.controller('MyCtrl', function ($scope) {

    //default state
    $scope.name = '';

    //all your init controller goodness in here
    this.$onInit = function () {
      $scope.name = 'Superhero';
    }
});

An advanced example of using component lifecycle:

The component lifecycle gives us the ability to handle component stuff in a good way. It allows us to create events for e.g. "init", "change" or "destroy" of an component. In that way we are able to manage stuff which is depending on the lifecycle of an component. This little example shows to register & unregister an $rootScope event listener $on. By knowing, that an event $on binded on $rootScope will not be undinded when the controller loses its reference in the view or getting destroyed we need to destroy a $rootScope.$on listener manually. A good place to put that stuff is $onDestroy lifecycle function of an component:

var myApp = angular.module('myApp',[]);

myApp.controller('MyCtrl', function ($scope, $rootScope) {

  var registerScope = null;

  this.$onInit = function () {
    //register rootScope event
    registerScope = $rootScope.$on('someEvent', function(event) {
        console.log("fired");
    });
  }

  this.$onDestroy = function () {
    //unregister rootScope event by calling the return function
    registerScope();
  }
});

The following code works fine:

@using (Html.BeginForm("Upload", "Upload", FormMethod.Post, 
                                      new { enctype = "multipart/form-data" }))
{
    @Html.ValidationSummary(true)
    <fieldset>
        Select a file <input type="file" name="file" />
        <input type="submit" value="Upload" />
    </fieldset>
}

and generates as expected:

<form action="/Upload/Upload" enctype="multipart/form-data" method="post">    
    <fieldset>
        Select a file <input type="file" name="file" />
        <input type="submit" value="Upload" />
    </fieldset>
</form>

On the other hand if you are writing this code inside the context of other server side construct such as an if or foreach you should remove the @ before the using. For example:

@if (SomeCondition)
{
    using (Html.BeginForm("Upload", "Upload", FormMethod.Post, 
                                      new { enctype = "multipart/form-data" }))
    {
        @Html.ValidationSummary(true)
        <fieldset>
            Select a file <input type="file" name="file" />
            <input type="submit" value="Upload" />
        </fieldset>
    }
}

As far as your server side code is concerned, here's how to proceed:

[HttpPost]
public ActionResult Upload(HttpPostedFileBase file) 
{
    if (file != null && file.ContentLength > 0) 
    {
        var fileName = Path.GetFileName(file.FileName);
        var path = Path.Combine(Server.MapPath("~/content/pics"), fileName);
        file.SaveAs(path);
    }
    return RedirectToAction("Upload");
}

Found it on another thread that solved my problem... was using an internet connection less network.

In that case copy the xsd files from the url and place it next to the beans.xml file and change the xsi:schemaLocation as under:

 <beans xmlns="http://www.springframework.org/schema/beans" 
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://www.springframework.org/schema/beans 
spring-beans-3.1.xsd">

Since Java 10, you can use local variable inference (a.k.a. "var") to make a lot of the already available answers less bloated. For example:

for (var entry : map.entrySet()) {
    System.out.println(entry.getKey() + " : " + entry.getValue());
}

In my case, I edited the known_hosts file with root user. So it changed the file ownership to root and jenkins user started throwing "[email protected]:xxxxxx/xxxx.git HEAD" returned status code 128: stdout: stderr: Host key verification failed" error while cloning git image. Reverting the ownership resolved the issue.

The error message means that it cannot locate your python executable or binary.

In many cases, it's installed at c:\python27. if it's not installed yet, you can install it with npm install --global windows-build-tools, which will only work if it hasn't been installed yet.

Adding it to the environment variables does not always work. A better alternative, is to just set it in the npm config.

npm config set python c:\python27\python.exe

append is appending an element to a list. if you want to extend the list with the new list you need to use extend.

>>> c = [1, 2, 3]
>>> c.extend(c)
>>> c
[1, 2, 3, 1, 2, 3]

<div class="form-group">
                    <div class="input-group col-md-5">
                    <div class="input-group-addon">
                    <span class="glyphicon glyphicon-envelope"></span> 
            </div>
                        <input class="form-control" type="text" name="text" placeholder="Enter Your Email Id" width="50px">

                    </div>
                    <input type="button" name="SIGNUP" value="SIGNUP">
            </div>

For those using something like babel stage-2 or transform-class-properties:

import React, { PropTypes, Component } from 'react';

export default class ExampleComponent extends Component {
   static contextTypes = {
      // some context types
   };

   static propTypes = {
      prop1: PropTypes.object
   };

   static defaultProps = {
      prop1: { foobar: 'foobar' }
   };

   ...

}

Update

As of React v15.5, PropTypes was moved out of the main React Package (link):

import PropTypes from 'prop-types';

Edit

As pointed out by @johndodo, static class properties are actually not a part of the ES7 spec, but rather are currently only supported by babel. Updated to reflect that.

You can check your g++ by command:

which g++
g++ --version

this will tell you which complier is currently it is pointing.

To switch to g++ 4.7 (assuming that you have installed it in your machine),run:

sudo update-alternatives --config gcc

There are 2 choices for the alternative gcc (providing /usr/bin/gcc).

  Selection    Path              Priority   Status
------------------------------------------------------------
  0            /usr/bin/gcc-4.6   60        auto mode
  1            /usr/bin/gcc-4.6   60        manual mode
* 2            /usr/bin/gcc-4.7   40        manual mode

Then select 2 as selection(My machine already pointing to g++ 4.7,so the *)

Once you switch the complier then again run g++ --version to check the switching has happened correctly.

Now compile your program with

g++ -std=c++11 your_file.cpp -o main

There's a way you can get this problem without having mixed newline problems (at least, in my shell, which is GNU bash v4.3.30):

#!/bin/bash
# foo.sh

function foo() {
    echo "I am quoting a thing `$1' inside a function."
}

while [ "$input" != "y" ]; do
    read -p "Hit `y' to continue: " -n 1 input
    echo
done

foo "What could possibly go wrong?"

$ ./foo.sh
./foo.sh: line 11: syntax error near unexpected token `done'
./foo.sh: line 11: `done'

This is because bash expands backticks inside double-quoted strings (see the bash manual on quoting and command substitution), and before finding a matching backtick, will interpret any additional double quotes as part of the command substitution:

$ echo "Command substitution happens inside double-quoted strings: `ls`"
Command substitution happens inside double-quoted strings: foo.sh
$ echo "..even with double quotes: `grep -E "^foo|wrong" foo.sh`"
..even with double quotes: foo "What could possibly go wrong?"

You can get around this by escaping the backticks in your string with a backslash, or by using a single-quoted string.

I'm not really sure why this only gives the one error message, but I think it has to do with the function definition:

#!/bin/bash
# a.sh

function a() {
    echo "Thing's `quoted'"
}
a
while true; do
    echo "Other `quote'"
done

#!/bin/bash
# b.sh

echo "Thing's `quoted'"
while true; do
    echo "Other `quote'"
done

$ ./a.sh
./a.sh: line 10: syntax error near unexpected token `done'
./a.sh: line 10: `done'
$ ./b.sh
./b.sh: command substitution: line 6: unexpected EOF while looking for matching `''
./b.sh: command substitution: line 9: syntax error: unexpected end of file
Thing's quote'
./b.sh: line 7: syntax error near unexpected token `done'
./b.sh: line 7: `done'

This looks like JavaScript Object Notation (JSON). You can parse JSON that resides in some variable, e.g. json_string, like so:

require 'json'
JSON.parse(json_string)

If you’re using an older Ruby, you may need to install the json gem.

There are also other implementations of JSON for Ruby that may fit some use-cases better:

• YAJL C Bindings for Ruby
• JSON::Stream

In Sourcetree: Just ignore a file in specified folder. Sourcetree will ask if you like to ignore all files in that folder. It's perfect!

Compiler by itself would not know that the conditions you have given are optimum .. meaning of this is you have covered all cases .. So therefore it always wants a return statement ... So either you can change last else if with else or just write return 0 after last else if ;`int binary(int val, int sorted[], int low, int high) { int mid = (low+high)/2;

if(high < low)
    return -1;

if(val < sorted[mid])
    return binary(val, sorted, low, mid-1);

else if(val > sorted[mid])
    return binary(val, sorted, mid+1, high);

else if(val == sorted[mid])
    return mid;
return 0; }`

Using the "file" command may be useful for this:

#!/bin/bash
check_file(){

if [ -z "${1}" ] ;then
 echo "Please input something"
 return;
fi

f="${1}"
result="$(file $f)"
if [[ $result == *"cannot open"* ]] ;then
        echo "NO FILE FOUND ($result) ";
elif [[ $result == *"directory"* ]] ;then
        echo "DIRECTORY FOUND ($result) ";
else
        echo "FILE FOUND ($result) ";
fi

}

check_file "${1}"

Output examples :

$ ./f.bash login
DIRECTORY FOUND (login: directory) 
$ ./f.bash ldasdas
NO FILE FOUND (ldasdas: cannot open `ldasdas' (No such file or  directory)) 
$ ./f.bash evil.php 
FILE FOUND (evil.php: PHP script, ASCII text) 

FYI: the answers above work but you can use -s to help in weird situations by checking for a valid file first:

#!/bin/bash

check_file(){
    local file="${1}"
    [[ -s "${file}" ]] || { echo "is not valid"; return; } 
    [[ -d "${file}" ]] && { echo "is a directory"; return; }
    [[ -f "${file}" ]] && { echo "is a file"; return; }
}

check_file ${1}

You could use the Fisher-Yates Shuffle (code adapted from this site):

function shuffle(array) {
    let counter = array.length;

    // While there are elements in the array
    while (counter > 0) {
        // Pick a random index
        let index = Math.floor(Math.random() * counter);

        // Decrease counter by 1
        counter--;

        // And swap the last element with it
        let temp = array[counter];
        array[counter] = array[index];
        array[index] = temp;
    }

    return array;
}

In C++ it is done like this:

#define LOCAL_PI 3.1415926535897932385 

double ToRadians(double degrees) 
{
  double radians = degrees * LOCAL_PI / 180;
  return radians;
}

double DirectDistance(double lat1, double lng1, double lat2, double lng2) 
{
  double earthRadius = 3958.75;
  double dLat = ToRadians(lat2-lat1);
  double dLng = ToRadians(lng2-lng1);
  double a = sin(dLat/2) * sin(dLat/2) + 
             cos(ToRadians(lat1)) * cos(ToRadians(lat2)) * 
             sin(dLng/2) * sin(dLng/2);
  double c = 2 * atan2(sqrt(a), sqrt(1-a));
  double dist = earthRadius * c;
  double meterConversion = 1609.00;
  return dist * meterConversion;
}

You have three options:

• Style links to look like buttons using CSS.

  Just look at the light blue "tags" under your question.

  It is possible, even to give them a depressed appearance when clicked (using pseudo-classes like :active), without any scripting. Lots of major sites, such as Google, are starting to make buttons out of CSS styles these days anyway, scripting or not.

• Put a separate <form> element around each one.

  As you mentioned in the question. Easy and will definitely work without Javascript (or even CSS). But it adds a little extra code which may look untidy.

• Rely on Javascript.

  Which is what you said you didn't want to do.

1. Remove the 'import R.java' line from your code. Its done by Eclipse in order to solve the problem.
2. Go to "note_edit.xml" file. Wherever you find "match_parent" as an attribute value, replace it with either "fill_parent" or "wrap_content".
3. Do a clean build. R.java will be generated automatically.

If you got this problem, it means "match_parent" property is not supported in your content. Instead, "fill_parent" is used.

"fill_parent: The view should be as big as its parent (minus padding). This constant is deprecated starting from API Level 8 and is replaced by match_parent. "

An update for Rails 5:

gem 'protected_attributes' 

doesn't seem to work anymore. But give:

gem 'protected_attributes_continued'

a try.

If you have the google collections library, Tom's answer can be simplified a lot by using ImmutableSet (http://google-collections.googlecode.com/svn/trunk/javadoc/com/google/common/collect/ImmutableSet.html)

This really removes a lot of clutter from the initialization proposed

private static final Set<String> VALUES =  ImmutableSet.of("AB","BC","CD","AE");

FWIW:

We had a situation where we needed to kill our iFrame when this "breaker" code showed up. So, I used the PHP function get_headers($url); to check out the remote URL before showing it in an iFrame. For better performance, I cached the results to a file so I was not making a HTTP connection each time.

Following worked for me in C++11:

template <typename Enum>
constexpr typename std::enable_if<std::is_enum<Enum>::value,
                                  typename std::underlying_type<Enum>::type>::type
to_integral(Enum const& value) {
    return static_cast<typename std::underlying_type<Enum>::type>(value);
}

UPDATE : see Mike Todd's solution for a complete answer.

$("#div1").animate({ scrollTop: $('#div1').height()}, 1000);

if you want it to be animated (over 1000 milliseconds).

$('#div1').scrollTop($('#div1').height())

if you want it instantaneous.

For reference using the [EnableCors()] approach will not work if you intercept the Message Pipeline using a DelegatingHandler. In my case was checking for an Authorization header in the request and handling it accordingly before the routing was even invoked, which meant my request was getting processed earlier in the pipeline so the [EnableCors()] had no effect.

In the end found an example CrossDomainHandler class (credit to shaunxu for the Gist) which handles the CORS for me in the pipeline and to use it is as simple as adding another message handler to the pipeline.

public class CrossDomainHandler : DelegatingHandler
    {
        const string Origin = "Origin";
        const string AccessControlRequestMethod = "Access-Control-Request-Method";
        const string AccessControlRequestHeaders = "Access-Control-Request-Headers";
        const string AccessControlAllowOrigin = "Access-Control-Allow-Origin";
        const string AccessControlAllowMethods = "Access-Control-Allow-Methods";
        const string AccessControlAllowHeaders = "Access-Control-Allow-Headers";

        protected override Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
        {
            bool isCorsRequest = request.Headers.Contains(Origin);
            bool isPreflightRequest = request.Method == HttpMethod.Options;
            if (isCorsRequest)
            {
                if (isPreflightRequest)
                {
                    return Task.Factory.StartNew(() =>
                    {
                        HttpResponseMessage response = new HttpResponseMessage(HttpStatusCode.OK);
                        response.Headers.Add(AccessControlAllowOrigin, request.Headers.GetValues(Origin).First());

                        string accessControlRequestMethod = request.Headers.GetValues(AccessControlRequestMethod).FirstOrDefault();
                        if (accessControlRequestMethod != null)
                        {
                            response.Headers.Add(AccessControlAllowMethods, accessControlRequestMethod);
                        }

                        string requestedHeaders = string.Join(", ", request.Headers.GetValues(AccessControlRequestHeaders));
                        if (!string.IsNullOrEmpty(requestedHeaders))
                        {
                            response.Headers.Add(AccessControlAllowHeaders, requestedHeaders);
                        }

                        return response;
                    }, cancellationToken);
                }
                else
                {
                    return base.SendAsync(request, cancellationToken).ContinueWith(t =>
                    {
                        HttpResponseMessage resp = t.Result;
                        resp.Headers.Add(AccessControlAllowOrigin, request.Headers.GetValues(Origin).First());
                        return resp;
                    });
                }
            }
            else
            {
                return base.SendAsync(request, cancellationToken);
            }
        }
    }

To use it add it to the list of registered message handlers

config.MessageHandlers.Add(new CrossDomainHandler());

Any preflight requests by the Browser are handled and passed on, meaning I didn't need to implement an [HttpOptions] IHttpActionResult method on the Controller.

You can execute raw query using ActiveRecord. And I will suggest to go with SQL block

query = <<-SQL 
  SELECT * 
  FROM payment_details
  INNER JOIN projects 
          ON projects.id = payment_details.project_id
  ORDER BY payment_details.created_at DESC
SQL

result = ActiveRecord::Base.connection.execute(query)

Convert String to Data

extension String {
    func toData() -> Data {
        return Data(self.utf8)
    }
}

Convert Data to String

extension Data {
      func toString() -> String {
          return String(decoding: self, as: UTF8.self)
      }
   }

This is kind of Flex/BlazeDS specific, but here's the solution I've come up with. Sorry if answering my own question is a faux pas.

    HttpServletRequest request = flex.messaging.FlexContext.getHttpRequest();

    Cookie[] cookies = request.getCookies();

    for (Cookie c:cookies)
    {
        log.debug(String.format("Cookie: %s, %s, domain: %s",c.getName(), c.getValue(),c.getDomain()));
    }

It works, I get the cookies. My problem was looking to Spring - BlazeDS had it. Spring probably does too, but I still don't know how to get to it.

I like re, but here is my solution without it:

from itertools import groupby
sep = ' ,-!?'
s = "Hey, you - what are you doing here!?"
print [''.join(g) for k, g in groupby(s, sep.__contains__) if not k]

sep.__contains__ is a method used by 'in' operator. Basically it is the same as

lambda ch: ch in sep

but is more convenient here.

groupby gets our string and function. It splits string in groups using that function: whenever a value of function changes - a new group is generated. So, sep.__contains__ is exactly what we need.

groupby returns a sequence of pairs, where pair[0] is a result of our function and pair[1] is a group. Using 'if not k' we filter out groups with separators (because a result of sep.__contains__ is True on separators). Well, that's all - now we have a sequence of groups where each one is a word (group is actually an iterable so we use join to convert it to string).

This solution is quite general, because it uses a function to separate string (you can split by any condition you need). Also, it doesn't create intermediate strings/lists (you can remove join and the expression will become lazy, since each group is an iterator)

Just try -webkit-flexbox. it's working for safari. webkit-flex safari will not taking.

You can do :

 System.out.println(nir[0].length);

But be aware that there's no real two-dimensional array in Java. Each "first level" array contains another array. Each of these arrays can be of different sizes. nir[0].length isn't necessarily the same size as nir[1].length.

$("#name", '#form2').val("Hello World")

Alternatively:

ALTER TABLE users
ADD COLUMN `status` INT(10) UNSIGNED NOT NULL AFTER `lastname`,
ADD COLUMN `log` VARCHAR(12) NOT NULL AFTER `lastname`,
ADD COLUMN `count` SMALLINT(6) NOT NULL AFTER `lastname`;

Will put them in the order you want while streamlining the AFTER statement.

This is a full solution for all android versions, I had a hard time with this too.

}

Also I want to add that the "upload page" like the one in this example, wont work on < 4 versions, since it has an image preview feature, if you want to make it work use a simple php upload without preview.

Update:

Please find the solution for lollipop devices here and thanks for gauntface

Update 2:

Complete solution for all android devices till oreo here and this is more advanced version, you should look into it, maybe it can help.

Browsers control a lot of this functionality but

<a href="http://www.yahoo.com" target="_blank">Go to Yahoo</a>

will attempt to open yahoo.com in a new window.

As mentioned in previous posts already, OPTIONS requests are there for a reason. If you have an issue with large response times from your server (e.g. overseas connection) you can also have your browser cache the preflight requests.

Have your server reply with the Access-Control-Max-Age header and for requests that go to the same endpoint the preflight request will have been cached and not occur anymore.

If you're converting an HTML doc into a PDF page, but the page spills onto two pages, try reducing the font size. Of course you can also decrease the spacing between paragraphs (with the CSS margin-top/margin-bottom styles), or even the left and right gutters with margins. But to my eye, keep things in proportion and just make the text a little smaller:

p { font-size: 90%; }

or

body { font-size: 9.5pt }

CURL OPERATION BETWEEN SERVER TO SERVER WITHOUT HTML FORM IN PHP USING MULTIPART/FORM-DATA

// files to upload

$filename = "https://example.s3.amazonaws.com/0.jpg";       

// URL to upload to (Destination server)

$url = "https://otherserver/image";

AND

    $curl = curl_init();

    curl_setopt_array($curl, array(
        CURLOPT_URL => $url,
        CURLOPT_RETURNTRANSFER => 1,
        CURLOPT_MAXREDIRS => 10,
        CURLOPT_TIMEOUT => 30,
        //CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
        CURLOPT_CUSTOMREQUEST => "POST",
        CURLOPT_POST => 1,
        CURLOPT_POSTFIELDS => file_get_contents($filename),
        CURLOPT_HTTPHEADER => array(
            //"Authorization: Bearer $TOKEN",
            "Content-Type: multipart/form-data",
            "Content-Length: " . strlen(file_get_contents($filename)),
            "API-Key: abcdefghi" //Optional if required
        ),
    ));

   $response = curl_exec($curl);

    $info = curl_getinfo($curl);
//echo "code: ${info['http_code']}";

//print_r($info['request_header']);

    var_dump($response);
    $err = curl_error($curl);

    echo "error";
    var_dump($err);
    curl_close($curl);

The other difference between divide and conquer and dynamic programming could be:

Divide and conquer:

1. Does more work on the sub-problems and hence has more time consumption.
2. In divide and conquer the sub-problems are independent of each other.

Dynamic programming:

1. Solves the sub-problems only once and then stores it in the table.
2. In dynamic programming the sub-problem are not independent.

In the future (perhaps) you will be able to use :nth-child(an+b of s)

Actually, browser support for the “of” filter is very limited. Only Safari seems to support the syntax.

https://css-tricks.com/almanac/selectors/n/nth-child/

I found the path and wrote it in the options

There is another approach. In my example you see some business logic in repository class that I use with dependency injection in ASP .NET MVC Core 3.1.

And here I want to get connectiongString for that business logic because probably another repository will have access to another database at all.

This pattern allows you in the same business logic repository have access to different databases.

C#

public interface IStatsRepository
{
            IEnumerable<FederalDistrict> FederalDistricts();
}

class StatsRepository : IStatsRepository
{
   private readonly DbContextOptionsBuilder<EFCoreTestContext>
                optionsBuilder = new DbContextOptionsBuilder<EFCoreTestContext>();
   private readonly IConfigurationRoot configurationRoot;

   public StatsRepository()
   {
       IConfigurationBuilder configurationBuilder = new ConfigurationBuilder().SetBasePath(Environment.CurrentDirectory)
           .AddJsonFile("appsettings.json", optional: true, reloadOnChange: true);
       configurationRoot = configurationBuilder.Build();
   }

   public IEnumerable<FederalDistrict> FederalDistricts()
   {
        var conn = configurationRoot.GetConnectionString("EFCoreTestContext");
        optionsBuilder.UseSqlServer(conn);

        using (var ctx = new EFCoreTestContext(optionsBuilder.Options))
        { 
            return ctx.FederalDistricts.Include(x => x.FederalSubjects).ToList();
        }
    }
}

appsettings.json

{
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft": "Warning",
      "Microsoft.Hosting.Lifetime": "Information"
    }
  },
  "AllowedHosts": "*",
  "ConnectionStrings": {
    "EFCoreTestContext": "Data Source=DESKTOP-GNJKL2V\\MSSQLSERVER2014;Database=Test;Trusted_Connection=True;MultipleActiveResultSets=true"
  }
}

You may be able to use absolute positioning.

The container box should be set to position: relative.

The top-right text should be set to position: absolute; top: 0; right: 0. The bottom-right text should be set to position: absolute; bottom: 0; right: 0.

You'll need to experiment with padding to stop the main contents of the box from running underneath the absolute positioned elements, as they exist outside the normal flow of the text contents.

I was able to overcome this by using "gcc" instead of "g++" for my compiler. I know this isn't an option for most people, but thought I'd mention it as a workaround option :)

Instead of using ->bindParam() you can pass the data only at the time of ->execute():

$data = [   ':item_name' => $_POST['item_name'],   ':item_type' => $_POST['item_type'],   ':item_price' => $_POST['item_price'],   ':item_description' => $_POST['item_description'],   ':image_location' => 'images/'.$_FILES['file']['name'],   ':status' => 0,   ':id' => 0, ];  $stmt->execute($data); 

In this way you would know exactly what values are going to be sent.

if using react:

const html = ReactDOM.findDOMNode(document.getElementsByTagName('html')[0]).outerHTML;

There's better support for this now through conda-env. You can, for example, now do:

name: sample_env
channels:
dependencies:
   - requests
   - bokeh>=0.10.0
   - pip:
     - "--editable=git+https://github.com/pythonforfacebook/facebook-sdk.git@8c0d34291aaafec00e02eaa71cc2a242790a0fcc#egg=facebook_sdk-master"

It's still calling pip under the covers, but you can now unify your conda and pip package specifications in a single environment.yml file.

If you wanted to update your root environment with this file, you would need to save this to a file (for example, environment.yml), then run the command: conda env update -f environment.yml.

It's more likely that you would want to create a new environment:

conda env create -f environment.yml (changed as supposed in the comments)

Try:

DataTable.Rows[RowNo].ItemArray[columnIndex].ToString()

(This is C# code. Change this to VB equivalent)

As indicated here https://stackoverflow.com/a/1632004/330867, you can implement it by "filtering" what is originating the exit of this page.

As mentionned in the comments, here's a new version of the code in the other question, which also include the ajax request you make in your question :

var canExit = true;

// For every function that will call an ajax query, you need to set the var "canExit" to false, then set it to false once the ajax is finished.

function checkCart() {
  canExit = false;
  $.ajax({
    url : 'index.php?route=module/cart/check',
    type : 'POST',
    dataType : 'json',
    success : function (result) {
       if (result) {
        canExit = true;
       }
    }
  })
}

$(document).on('click', 'a', function() {canExit = true;}); // can exit if it's a link
$(window).on('beforeunload', function() {
    if (canExit) return null; // null will allow exit without a question
    // Else, just return the message you want to display
    return "Do you really want to close?";
});

Important: You shouldn't have a global variable defined (here canExit), this is here for simpler version.

Note that you can't override completely the confirm message (at least in chrome). The message you return will only be prepended to the one given by Chrome. Here's the reason : How can I override the OnBeforeUnload dialog and replace it with my own?

At the server you can check the MIME type, lookup flv mime type here or on google.

You should be checking that the mime type is

video/x-flv

If you were using a FileUpload in C# for instance, you could do

FileUpload.PostedFile.ContentType == "video/x-flv"

    var p=document.getElementById('childId').parentNode;
    var c=document.getElementById('childId');
    p.removeChild(c);
    alert('Deleted');

p is parent node and c is child node
parentNode is a JavaScript variable which contains parent reference

Easy to understand

Try adding WorksheetFunction:

If Not IsError(Application.WorksheetFunction.Match(ValueToSearchFor, RangeToSearchIn, 0)) Then
' String is in range

An application pool is a group of urls served by worker processors or set of worker processors.

There can exist any number of application pools.

In IIS it is possible to create more than one application pool.

An application in different application pool runs in different worker processors.

Advantage: If an error occurred in one application pool will not effect the applications running in another application pool.

This works perfectly fine with me. It takes label and format the value.

options: {
        tooltips: {
            callbacks: {
                label: function(tooltipItem, data) {

                    let label = data.labels[tooltipItem.index];
                    let value = data.datasets[tooltipItem.datasetIndex].data[tooltipItem.index];
                    return ' ' + label + ': ' + value + ' %';

                }
            }
        }
    }

Use $ne instead of $not

http://docs.mongodb.org/manual/reference/operator/ne/#op._S_ne

db.collections.find({"name": {$ne: ""}});

Since I can't comment on Jasper's answer, I'd like to point out a small bug in his solution:

str.replace(/[^a-z0-9\s]/gi, '').replace(/[_\s]/g, '-');

The problem is that first code removes all the hyphens and then tries to replace them :) You should reverse the replace calls and also add hyphen to second replace regex. Like this:

str.replace(/[_\s]/g, '-').replace(/[^a-z0-9-\s]/gi, '');

This is an old question, but this is another way, using jQuery to reuse the popover and to keep using the original bootstrap data attributes to make it more semantic:

The link

<a href="#" rel="popover" data-trigger="focus" data-popover-content="#popover">
   Show it!
</a>

Custom content to show

<!-- Let's show the Bootstrap nav on the popover-->
<div id="list-popover" class="hide">
    <ul class="nav nav-pills nav-stacked">
        <li><a href="#">Action</a></li>
        <li><a href="#">Another action</a></li>
        <li><a href="#">Something else here</a></li>
        <li><a href="#">Separated link</a></li>
    </ul>
</div>

Javascript

$('[rel="popover"]').popover({
    container: 'body',
    html: true,
    content: function () {
        var clone = $($(this).data('popover-content')).clone(true).removeClass('hide');
        return clone;
    }
});

You need to use javaScript's parseInt() method to turn the strings back into numbers. Right now they are strings so adding two strings concatenates them, which is why you're getting "12".

Here is the SetForegroundWindow equivalent:

form.Activate();

I have seen people doing weird things like:

this.TopMost = true;
this.Focus();
this.BringToFront();
this.TopMost = false;

Consider using CloudBerry Explorer freeware to upload the full folder structure to Amazon S3.

Consider my code:

import os


def readFile(filename):
    filehandle = open(filename)
    print filehandle.read()
    filehandle.close()



fileDir = os.path.dirname(os.path.realpath('__file__'))
print fileDir

#For accessing the file in the same folder
filename = "same.txt"
readFile(filename)

#For accessing the file in a folder contained in the current folder
filename = os.path.join(fileDir, 'Folder1.1/same.txt')
readFile(filename)

#For accessing the file in the parent folder of the current folder
filename = os.path.join(fileDir, '../same.txt')
readFile(filename)

#For accessing the file inside a sibling folder.
filename = os.path.join(fileDir, '../Folder2/same.txt')
filename = os.path.abspath(os.path.realpath(filename))
print filename
readFile(filename)

This code will change the color of the placeholder using the ::placeholder selector.

::-webkit-input-placeholder {

    color: red;
}

:-ms-input-placeholder { 
    /* Internet Explorer */
    color: red;
}

::placeholder {
    color: red;
}

This works!

A primary key is not required. A foreign key is not required either. You can construct a query joining two tables on any column you wish as long as the datatypes either match or are converted to match. No relationship needs to explicitly exist.

To do this you use an outer join:

select tablea.code, tablea.name, tableb.location from tablea left outer join 
tableb on tablea.code = tableb.code

join with out relation

SQL join

I hope your stored procedure is not doing a cursor loop!

If not, take the query from your stored procedure and integrate that query within the query you are posting here:

SELECT t.TenantName, t.CarPlateNumber, t.CarColor, t.Sex, t.SSNO, t.Phone, t.Memo,
        u.UnitNumber,
        p.PropertyName
        ,dt.TenantBalance
FROM tblTenant t
    LEFT JOIN tblRentalUnit u ON t.UnitID = u.ID
    LEFT JOIN tblProperty   p ON u.PropertyID = p.ID
    LEFT JOIN (SELECT ID, SUM(ISNULL(trans.Amount,0)) AS TenantBalance
                   FROM tblTransaction
                   GROUP BY tenant.ID
              ) dt ON t.ID=dt.ID
ORDER BY p.PropertyName, t.CarPlateNumber

If you are doing something more than a query in your stored procedure, create a temp table and execute the stored procedure into this temp table and then join to that in your query.

create procedure test_proc
as
  select 1 as x, 2 as y
  union select 3,4 
  union select 5,6 
  union select 7,8 
  union select 9,10
  return 0
go 

create table #testing
(
  value1   int
  ,value2  int
)

INSERT INTO #testing
exec test_proc


select
  *
  FROM #testing

Here's an approach in Swift, using a UIButton extension to add an IBInspectable, called highlightedBackgroundColor. Similar to subclassing, without requiring a subclass.

private var HighlightedBackgroundColorKey = 0
private var NormalBackgroundColorKey = 0

extension UIButton {

    @IBInspectable var highlightedBackgroundColor: UIColor? {
        get {
            return objc_getAssociatedObject(self, &HighlightedBackgroundColorKey) as? UIColor
        }

        set(newValue) {
            objc_setAssociatedObject(self,
                &HighlightedBackgroundColorKey, newValue, UInt(OBJC_ASSOCIATION_RETAIN))
        }
    }

    private var normalBackgroundColor: UIColor? {
        get {
            return objc_getAssociatedObject(self, &NormalBackgroundColorKey) as? UIColor
        }

        set(newValue) {
            objc_setAssociatedObject(self,
                &NormalBackgroundColorKey, newValue, UInt(OBJC_ASSOCIATION_RETAIN))
        }
    }

    override public var backgroundColor: UIColor? {
        didSet {
            if !highlighted {
                normalBackgroundColor = backgroundColor
            }
        }
    }

    override public var highlighted: Bool {
        didSet {
            if let highlightedBackgroundColor = self.highlightedBackgroundColor {
                if highlighted {
                    backgroundColor = highlightedBackgroundColor
                } else {
                    backgroundColor = normalBackgroundColor
                }
            }
        }
    }
}

I hope this helps.

This uses the modulo 10 method to figure out each digit in a number greater than 0, then this will reverse the order of the array. This is assuming you are not using "0" as a starting digit.

This is modified to take in user input. This array is originally inserted backwards, so I had to use the Collections.reverse() call to put it back into the user's order.

    Scanner scanNumber = new Scanner(System.in);
    int userNum = scanNumber.nextInt(); // user's number

    // divides each digit into its own element within an array
    List<Integer> checkUserNum = new ArrayList<Integer>();
    while(userNum > 0) {
        checkUserNum.add(userNum % 10);
        userNum /= 10;
    }

    Collections.reverse(checkUserNum); // reverses the order of the array

    System.out.print(checkUserNum);

WHERE is first, then you GROUP the result of the query, and last but not least HAVING-clause is taken to filter the grouped result. This is the "logical" order, I don't know how this is technically implemented in the engine.

Checking your linked site, you may include a script tag passing a ?var=desiredVarName parameter which will be set as a global variable containing the IP address:

<script type="text/javascript" src="http://l2.io/ip.js?var=myip"></script>
                                                      <!-- ^^^^ -->
<script>alert(myip);</script>

Demo

I believe I don't have to say that this can be easily spoofed (through either use of proxies or spoofed request headers), but it is worth noting in any case.

HTTPS support

In case your page is served using the https protocol, most browsers will block content in the same page served using the http protocol (that includes scripts and images), so the options are rather limited. If you have < 5k hits/day, the Smart IP API can be used. For instance:

<script>
var myip;
function ip_callback(o) {
    myip = o.host;
}
</script>
<script src="https://smart-ip.net/geoip-json?callback=ip_callback"></script>
<script>alert(myip);</script>

Demo

Edit: Apparently, this https service's certificate has expired so the user would have to add an exception manually. Open its API directly to check the certificate state: https://smart-ip.net/geoip-json

With back-end logic

The most resilient and simple way, in case you have back-end server logic, would be to simply output the requester's IP inside a <script> tag, this way you don't need to rely on external resources. For example:

PHP:

<script>var myip = '<?php echo $_SERVER['REMOTE_ADDR']; ?>';</script>

There's also a more sturdy PHP solution (accounting for headers that are sometimes set by proxies) in this related answer.

C#:

<script>var myip = '<%= Request.UserHostAddress %>';</script>

Another possible situation: accessing parent (a template class) member in a template class.

Fix method: using the parent class member by its full name (by prefixing this-> or parentClassName:: to the name of the member).

see: templates: parent class member variables not visible in inherited class

It's due to you sending one object, and you're expecting two parameters.

Try this and you'll see:

public class UserDetails
{
   public string username { get; set; }
   public string password { get; set; }
}

public JsonResult Login(UserDetails data)
{
   string error = "";
   //the rest of your code
}

First of all you should configure $resource in different manner: without query params in the URL. Default query parameters may be passed as properties of the second parameter in resource(url, paramDefaults, actions). It is also to be mentioned that you configure get method of resource and using query instead.

Service

angular.module('admin.services', ['ngResource'])       
  // GET TASK LIST ACTIVITY
  .factory('getTaskService', function($resource) {
    return $resource(
      '../rest/api.php',
      { method: 'getTask', q: '*' }, // Query parameters
      {'query': { method: 'GET' }}
    );
  })

You can use this code in case you want to change the color programmatically

floating.setBackgroundTintList(getResources().getColorStateList(R.color.vermelho));

var Hello = React.createClass({
    render: function() {
      return (
        <div className="divClass">
           <img src={this.props.url} alt={`${this.props.title}'s picture`}  className="img-responsive" />
           <span>Hello {this.props.name}</span>
        </div>
      );
    }
});

SQLite is database engine, .sqlite or .db should be a database. If you don't need to program anything, you can use a GUI like sqlitebrowser or anything like that to view the database contents.

^{Note: Though my original answer attracted several upvotes, I decided that I could do much better. You can find my original (simplistic and misguided) answer in the edit history.}

If Microsoft had the intent of providing a means of outputting a blank line from cmd.exe, Microsoft surely would have documented such a simple operation. It is this omission that motivated me to ask this question.

So, because a means for outputting a blank line from cmd.exe is not documented, arguably one should consider any suggestion for how to accomplish this to be a hack. That means that there is no known method for outputting a blank line from cmd.exe that is guaranteed to work (or work efficiently) in all situations.

With that in mind, here is a discussion of methods that have been recommended for outputting a blank line from cmd.exe. All recommendations are based on variations of the echo command.

echo.

While this will work in many if not most situations, it should be avoided because it is slower than its alternatives and actually can fail (see here, here, and here). Specifically, cmd.exe first searches for a file named echo and tries to start it. If a file named echo happens to exist in the current working directory, echo. will fail with:

'echo.' is not recognized as an internal or external command,
operable program or batch file.

echo:
echo\

At the end of this answer, the author argues that these commands can be slow, for instance if they are executed from a network drive location. A specific reason for the potential slowness is not given. But one can infer that it may have something to do with accessing the file system. (Perhaps because : and \ have special meaning in a Windows file system path?)

However, some may consider these to be safe options since : and \ cannot appear in a file name. For that or another reason, echo: is recommended by SS64.com here.

echo(
echo+
echo,
echo/
echo;
echo=
echo[
echo]

This lengthy discussion includes what I believe to be all of these. Several of these options are recommended in this SO answer as well. Within the cited discussion, this post ends with what appears to be a recommendation for echo( and echo:.

My question at the top of this page does not specify a version of Windows. My experimentation on Windows 10 indicates that all of these produce a blank line, regardless of whether files named echo, echo+, echo,, ..., echo] exist in the current working directory. (Note that my question predates the release of Windows 10. So I concede the possibility that older versions of Windows may behave differently.)

In this answer, @jeb asserts that echo( always works. To me, @jeb's answer implies that other options are less reliable but does not provide any detail as to why that might be. Note that @jeb contributed much valuable content to other references I have cited in this answer.

Conclusion: Do not use echo.. Of the many other options I encountered in the sources I have cited, the support for these two appears most authoritative:

echo(
echo:

But I have not found any strong evidence that the use of either of these will always be trouble-free.

Example Usage:

@echo off
echo Here is the first line.
echo(
echo There is a blank line above this line.

Expected output:

Here is the first line.

There is a blank line above this line.

I sometimes encounter the same issue. I can only answer your second bullet, because I am not as expert in R as I am with other languages. I have found that the standard for loop has some unexpected results. Say x = 0

for (i in 1:x) {
  print(i)
}

The output is

[1] 1
[1] 0

Whereas with python, for example

for i in range(x):
  print i

does nothing. The loop is not entered.

I expected that if x = 0 that in R, the loop would not be entered. However, 1:0 is a valid range of numbers. I have not yet found a good workaround besides having an if statement wrapping the for loop

An alternative to NCover can be PartCover, is an open source code coverage tool for .NET very similar to NCover, it includes a console application, a GUI coverage browser, and XSL transforms for use in CruiseControl.NET.

It is a very interesting product.

OpenCover has replaced PartCover.

It would be good to know what your purpose is, why you want to initialize the keys in the first place. I am not sure you need to do that at all.

1) If you want to count the number of occurrences of keys, you can just do:

Definition = {}
# ...
Definition[key] = Definition.get(key, 0) + 1

2) If you want to get None (or some other value) later for keys that you did not encounter, again you can just use the get() method:

Definition.get(key)  # returns None if key not stored
Definition.get(key, default_other_than_none)

3) For all other purposes, you can just use a list of the expected keys, and check if the keys found later match those.

For example, if you only want to store values for those keys:

expected_keys = ['apple', 'banana']
# ...
if key_found in expected_keys:
    Definition[key_found] = value

Or if you want to make sure all expected keys were found:

assert(all(key in Definition for key in expected_keys))

You just try the following code.It will delete all the sms that are all in phone (Received or Sent)

Uri uri = Uri.parse("content://sms");

ContentResolver contentResolver = getContentResolver();

Cursor cursor = contentResolver.query(uri, null, null, null,
  null);



while (cursor.moveToNext()) {

 long thread_id = cursor.getLong(1);
 Uri thread = Uri.parse("content://sms/conversations/"
   + thread_id);
 getContentResolver().delete(thread, null, null);
}

You can use Apache commons-io for this task:

Refer to this method:

public static byte[] readFileToByteArray(File file) throws IOException

Update:

Java 7 way:

byte[] bytes = Files.readAllBytes(Paths.get(filename));

and if it is a text file and you want to convert it to String (change encoding as needed):

StandardCharsets.UTF_8.decode(ByteBuffer.wrap(bytes)).toString()

Use otool:

otool -TV your.dylib

OR

nm -g your.dylib

it is very simple after exporting the Cert.p12 and key.p12, Please find below command for the generating 'apns' .pem file.

https://www.sslshopper.com/ssl-converter.html ?

command to create apns-dev.pem from Cert.pem and Key.pem
?    

openssl rsa -in Key.pem -out apns-dev-key-noenc.pem
?    

cat Cert.pem apns-dev-key-noenc.pem > apns-dev.pem

Above command is useful for both Sandbox and Production.

I have used this command to troubleshoot client certificate negotiation:

openssl s_client -connect www.test.com:443 -prexit

The output will probably contain "Acceptable client certificate CA names" and a list of CA certificates from the server, or possibly "No client certificate CA names sent", if the server doesn't always require client certificates.

First, you're using the modifiers under an incorrect assumption.

Pattern.MULTILINE or (?m) tells Java to accept the anchors ^ and $ to match at the start and end of each line (otherwise they only match at the start/end of the entire string).

Pattern.DOTALL or (?s) tells Java to allow the dot to match newline characters, too.

Second, in your case, the regex fails because you're using the matches() method which expects the regex to match the entire string - which of course doesn't work since there are some characters left after (\\W)*(\\S)* have matched.

So if you're simply looking for a string that starts with User Comments:, use the regex

^\s*User Comments:\s*(.*)

with the Pattern.DOTALL option:

Pattern regex = Pattern.compile("^\\s*User Comments:\\s+(.*)", Pattern.DOTALL);
Matcher regexMatcher = regex.matcher(subjectString);
if (regexMatcher.find()) {
    ResultString = regexMatcher.group(1);
} 

ResultString will then contain the text after User Comments:

The attribute that stores the classes in use is className.

So you can say:

if (document.body.className.match(/\bmyclass\b/)) {
    ....
}

If you're using .NET Core 3.0, you can use System.Text.Json (which is now built-in) to deserialize JSON.

The first step is to create classes to model the JSON. There are many tools which can help with this, and some of the answers here list them.

Some options are http://json2csharp.com, http://app.quicktype.io, or use Visual Studio (menu Edit → Paste Special → Paste JSON as classes).

public class Person
{
    public string Id { get; set; }
    public string Name { get; set; }
}

public class Response
{
    public List<Person> Data { get; set; }
}

Then you can deserialize using:

var people = JsonSerializer.Deserialize<Response>(json);

If you need to add settings, such as camelCase handling, then pass serializer settings into the deserializer like this:

var options = new JsonSerializerOptions() { PropertyNamingPolicy = JsonNamingPolicy.CamelCase };
var person = JsonSerializer.Deserialize<Response>(json, options);

The encoding declaration identifies which encoding is used to represent the characters in the document.

More on the XML Declaration here: http://msdn.microsoft.com/en-us/library/ms256048.aspx

try this one

return Content("<form action='actionname' id='frmTest' method='post'><input type='hidden' name='someValue' value='" + someValue + "' /><input type='hidden' name='anotherValue' value='" + anotherValue + "' /></form><script>document.getElementById('frmTest').submit();</script>");

You're looking for the cunningly named Registry.GetValue method.

You would need to implement the interface and define the compareTo() method. For a good tutorial go to - Tutorials point link or MyKongLink

This is not a bug- you can only transition on ordinal/calculable properties (an easy way of thinking of this is any property with a numeric start and end number value..though there are a few exceptions).

This is because transitions work by calculating keyframes between two values, and producing an animation by extrapolating intermediate amounts.

visibility in this case is a binary setting (visible/hidden), so once the transition duration elapses, the property simply switches state, you see this as a delay- but it can actually be seen as the final keyframe of the transition animation, with the intermediary keyframes not having been calculated (what constitutes the values between hidden/visible? Opacity? Dimension? As it is not explicit, they are not calculated).

opacity is a value setting (0-1), so keyframes can be calculated across the duration provided.

A list of transitionable (animatable) properties can be found here

From the fine manual:

ALTER TABLE mytable ALTER COLUMN mycolumn DROP NOT NULL;

There's no need to specify the type when you're just changing the nullability.

I've used the following code a few times and it works sweet:

$("body").click(function(e){ 
    // Check what has been clicked:
    var target = $(e.target); 
    if(target.is("#target")){
    // The target was clicked
    // Do something...
  }
});

Use the stringi package:

require(stringi)

group<-data.frame(c("12357e", "12575e", "197e18", "e18947"))
stri_replace_all(group[,1], "", fixed="e")
[1] "12357" "12575" "19718" "18947"

You can use Array.push() for appending elements to an array.

For deleting, it is best to use this.$delete(array, index) for reactive objects.

Vue.delete( target, key ): Delete a property on an object. If the object is reactive, ensure the deletion triggers view updates. This is primarily used to get around the limitation that Vue cannot detect property deletions, but you should rarely need to use it.

https://vuejs.org/v2/api/#Vue-delete

If you use this:

contentType: "application/json"

AJAX won't sent GET or POST params to the server.... dont know why.

It took me hours to lear it today.

Just Use:

$.ajax(
  { url : 'http://blabla.com/wsGetReport.php',
    data : myFormData, type : 'POST', dataType : 'json', 
    // contentType: "application/json", 
    success : function(wsQuery) { }
  }
)

I got the same error.

I was refering a VS2010 DLL in a VS2012 project.

Just recompiled the DLL on VS2012 and now everything is fine.

function is_mobile_valid(string_or_number){
            var mobile=string_or_number;
            if(mobile.length!=10){
                return false;

            }
            intRegex = /[0-9 -()+]+$/;
            is_mobile=true;
            for ( var i=0; i < 10; i++) {
                if(intRegex.test(mobile[i]))
                     { 
                     continue;
                     }
                    else{
                        is_mobile=false;
                        break;
                    }
                 }
            return is_mobile;

}

You can just check by calling the function is_mobile_valid(your_string_of_mobile_number);

We can use refs in another way as-

We are going to create a Parent element, it will render a <Child/> component. As you can see, the component that will be rendered, you need to add the ref attribute and provide a name for it.
Then, the triggerChildAlert function, located in the parent class will access the refs property of the this context (when the triggerChildAlert function is triggered will access the child reference and it will has all the functions of the child element).

class Parent extends React.Component {
    triggerChildAlert(){
        this.refs.child.callChildMethod();
        // to get child parent returned  value-
        // this.value = this.refs.child.callChildMethod();
        // alert('Returned value- '+this.value);
    }

    render() {
        return (
            <div>
                {/* Note that you need to give a value to the ref parameter, in this case child*/}
                <Child ref="child" />
                <button onClick={this.triggerChildAlert}>Click</button>
            </div>
        );
    }
}  

Now, the child component, as theoretically designed previously, will look like:

class Child extends React.Component {
    callChildMethod() {
        alert('Hello World');
        // to return some value
        // return this.state.someValue;
    }

    render() {
        return (
            <h1>Hello</h1>
        );
    }
}

Hope will help you !

You can try this.. My own version of it..

funcc() {
while true ; do 
for i in \| \/ \- \\ \| \/ \- \\; do 
  echo -n -e "\r$1  $i  "
sleep 0.5
done  
#echo -e "\r                                                                                      "
[ -f /tmp/print-stat ] && break 2
done
}

funcc "Checking Kubectl" & &>/dev/null
sleep 5
touch /tmp/print-stat
echo -e "\rPrint Success                  "

Like this:

import java.util.*;
Set<Integer> a = new HashSet<Integer>();
a.add( 1);
a.add( 2);
a.add( 3);

Or adding from an Array/ or multiple literals; wrap to a list, first.

Integer[] array = new Integer[]{ 1, 4, 5};
Set<Integer> b = new HashSet<Integer>();
b.addAll( Arrays.asList( b));         // from an array variable
b.addAll( Arrays.asList( 8, 9, 10));  // from literals

To get the intersection:

// copies all from A;  then removes those not in B.
Set<Integer> r = new HashSet( a);
r.retainAll( b);
// and print;   r.toString() implied.
System.out.println("A intersect B="+r);

Hope this answer helps. Vote for it!

Daniel Kutik's answer is correct, but it can be even more safe, with database renaming.

So, the truly safe way is:

1. Create new database with the different encoding and name
2. Dump your database
3. Restore dump to the new DB
4. Test that your application runs correctly with the new DB
5. Rename old DB to something meaningful
6. Rename new DB
7. Test application again
8. Drop the old database

In case of emergency, just rename DBs back

Simple-read but precise solution would be:

func nowAsUnixMilliseconds(){
    return time.Now().Round(time.Millisecond).UnixNano() / 1e6
}

This function:

1. Correctly rounds the value to the nearest millisecond (compare with integer division: it just discards decimal part of the resulting value);
2. Does not dive into Go-specifics of time.Duration coercion — since it uses a numerical constant that represents absolute millisecond/nanosecond divider.

P.S. I've run benchmarks with constant and composite dividers, they showed almost no difference, so feel free to use more readable or more language-strict solution.

You can use the WebFont module, which greatly simplifies the process.

render(){
  webfont.load({
     custom: {
       families: ['MyFont'],
       urls: ['/fonts/MyFont.woff']
     }
  });
  return (
    <div style={your style} >
      your text!
    </div>
  );
}

In case anyone else is wondering, you can use is_ to generate foo IS NULL:

>>> from sqlalchemy.sql import column
>>> print column('foo').is_(None)
foo IS NULL
>>> print column('foo').isnot(None)
foo IS NOT NULL

I was having the same sort of problem. Apparently it's simply because PHP doesn't recognise utf-8.

I was tearing my hair out at first when a '£' sign kept showing up as '£', despite it appearing ok in DreamWeaver. Eventually I remembered I had been having problems with links relative to the index file, when the pages, if viewed directly would work with slideshows, but not when used with an include (but that's beside the point. Anyway I wondered if this might be a similar problem, so instead of putting into the page that I was having problems with, I simply put it into the index.php file - problem fixed throughout.

I build my own solution using va_arg. This solution is C++98 compliant.

#include <cstdarg>
#include <iostream>
#include <vector>

template <typename T>
std::vector<T> initVector (int len, ...)
{
  std::vector<T> v;
  va_list vl;
  va_start(vl, len);
  for (int i = 0; i < len; ++i)
    v.push_back(va_arg(vl, T));
  va_end(vl);
  return v;
}

int main ()
{
  std::vector<int> v = initVector<int> (7,702,422,631,834,892,104,772);
  for (std::vector<int>::const_iterator it = v.begin() ; it != v.end(); ++it)
    std::cout << *it << std::endl;
  return 0;
}

Demo

Try

//*[text()='qwerty'] because . is your current element

You can use something like this:

List<Object[]> list = em.createQuery("SELECT p.field1, p.field2 FROM Entity p").getResultList();

then you can iterate over it:

for (Object[] obj : list){
    System.out.println(obj[0]);
    System.out.println(obj[1]);
}

BUT if you have only one field in query, you get a list of the type not from Object[]

If you're going to run a little console app, you may as well install clrver.exe from the .NET SDK. I don't think you can get cleaner than that. This isn't my answer (but I happen to agree), I found it here.

I was going to write up my own explanation but this Wikipedia article pretty much sums it up.

Here is the basic concept:

Copy-on-write (sometimes referred to as "COW") is an optimization strategy used in computer programming. The fundamental idea is that if multiple callers ask for resources which are initially indistinguishable, you can give them pointers to the same resource. This function can be maintained until a caller tries to modify its "copy" of the resource, at which point a true private copy is created to prevent the changes becoming visible to everyone else. All of this happens transparently to the callers. The primary advantage is that if a caller never makes any modifications, no private copy need ever be created.

Also here is an application of a common use of COW:

The COW concept is also used in maintenance of instant snapshot on database servers like Microsoft SQL Server 2005. Instant snapshots preserve a static view of a database by storing a pre-modification copy of data when underlaying data are updated. Instant snapshots are used for testing uses or moment-dependent reports and should not be used to replace backups.

>>> k = [[1, 2], [4], [5, 6, 2], [1, 2], [3], [4]]
>>> k = sorted(k)
>>> k
[[1, 2], [1, 2], [3], [4], [4], [5, 6, 2]]
>>> dedup = [k[i] for i in range(len(k)) if i == 0 or k[i] != k[i-1]]
>>> dedup
[[1, 2], [3], [4], [5, 6, 2]]

I don't know if it's necessarily faster, but you don't have to use to tuples and sets.

Your code was right except you are not passing the JSON keys as strings.

It should have double or single quotes around it

{ "field1": "hello", "field2" : "hello2"}

$.ajax(
   {
      type: 'post',
      url: 'superman',
      data: { 
        "field1": "hello", // Quotes were missing
        "field2": "hello1" // Here also
      },
      success: function (response) {
        alert(response);
      },
      error: function () {
        alert("error");
      }
   }
);

The most straightforward way:

long millisInDay = 60 * 60 * 24 * 1000;
long currentTime = new Date().getTime();
long dateOnly = (currentTime / millisInDay) * millisInDay;
Date clearDate = new Date(dateOnly);

Check out this GitHub repository that describes best practices for AngularJS apps. It has naming conventions for different components. It is not complete, but it is community-driven so everyone can contribute.

I advise you check out http://wurfl.io/

In a nutshell, if you import a tiny JS file:

<script type='text/javascript' src="//wurfl.io/wurfl.js"></script>

you will be left with a JSON object that looks like:

{
 "complete_device_name":"Google Nexus 7",
 "is_mobile":true,
 "form_factor":"Tablet"
}

(that's assuming you are using a Nexus 7, of course) and you will be able to do things like:

if(WURFL.form_factor == "Tablet"){
    //dostuff();
}

This is what you are looking for.

casting of generics is not possible, but if you define the list in another way it is possible to store TestB in it:

List<? extends TestA> myList = new ArrayList<TestA>();

You still have type checking to do when you are using the objects in the list.

In addition to the accepted answer you can use this if you want to group by multiple columns:

<ul ng-repeat="(key, value) in players | groupBy: '[team,name]'">

You have a pointer to a char. So as your system knows, on that memory address there is a char value on sizeof(char) space. When you cast it up to int*, you will work with data of sizeof(int), so you will print your char and some memory-garbage after it as an integer.

$('#some_select_box option:selected').remove();

Exporting the credential also work, In linux:

export AWS_SECRET_ACCESS_KEY="XXXXXXXXXXXX"
export AWS_ACCESS_KEY_ID="XXXXXXXXXXX"

Subtract from another date object

var d = new Date();

d.setHours(d.getHours() - 2);

• Complete reference list for Date object

You can verify where your Setting.xml is by pressing shortcut Ctrl+3, you will see Quick Access on top right side of Eclipse, then search setting.xml in searchbox. If you got setting.xml it will show up in search. Click that, and it will open the window showing directory path wherever it is stored. Your Maven Global Settings should be as such:

Global Setting C:\maven\apache-maven-3.5.0\conf\settings.xml
User Setting %userprofile%\\.m2\setting.xml
You can use global setting usually and leave the second option user setting untouched. Store your setting.xml in Global Setting

A generic, pure Java solution..

For Windows and MacOS, the following can be inferred (most of the time)...

public static boolean isJDK() {
    String path = System.getProperty("sun.boot.library.path");
    if(path != null && path.contains("jdk")) {
        return true;
    }
    return false;
}

However... on Linux this isn't as reliable... For example...

• Many JREs on Linux contain openjdk the path
• There's no guarantee that the JRE doesn't also contain a JDK.

So a more fail-safe approach is to check for the existence of the javac executable.

public static boolean isJDK() {
    String path = System.getProperty("sun.boot.library.path");
    if(path != null) {
        String javacPath = "";
        if(path.endsWith(File.separator + "bin")) {
            javacPath = path;
        } else {
            int libIndex = path.lastIndexOf(File.separator + "lib");
            if(libIndex > 0) {
                javacPath = path.substring(0, libIndex) + File.separator + "bin";
            }
        }
        if(!javacPath.isEmpty()) {
            return new File(javacPath, "javac").exists() || new File(javacPath, "javac.exe").exists();
        }
    }
    return false;
}

Warning: This will still fail for JRE + JDK combos which report the JRE's sun.boot.library.path identically between the JRE and the JDK. For example, Fedora's JDK will fail (or pass depending on how you look at it) when the above code is run. See unit tests below for more info...

It may have been an oversight of other answers, or perhaps it is a requirement of the user to indeed need console output, but the obvious answer to me is to create a secondary window that can be shown or hidden (with a checkbox or button) that shows all messages by appending lines of text to a text box widget and use that as a console?

The benefits of such a solution are:

• A simple solution (providing all it displays is a simple log).
• The ability to dock the 'console' widget onto the main application window. (In Qt, anyhow).
• The ability to create many consoles (if more than 1 thread, etc).
• A pretty easy change from local console output to sending log over network to a client.

Hope this gives you food for thought, although I am not in any way yet qualified to postulate on how you should do this, I can imagine it is something very achievable by any one of us with a little searching / reading!

In Kotlin you can do this...

Service:

class MyService : Service() {
    init {
        instance = this
    }

    companion object {
        lateinit var instance: MyService

        fun terminateService() {
            instance.stopSelf()
        }
    }
}

In your activity (or anywhere in your app for that matter):

btn_terminate_service.setOnClickListener {
    MyService.terminateService()
}

Note: If you have any pending intents showing a notification in Android's status bar, you may want to terminate that as well.

With System.getProperty("user.dir") you get the "Base of non-absolute paths" look at

Java Library Description

Though it is an old question, it is still a valid one.

Expected behavior:

• Show selected file name after upload.
• Do not do anything if the user clicks Cancel.
• Show the file name even when the user selects the same file.

Code with a demonstration:

<!DOCTYPE html>
<html>

<head>
  <title>File upload event</title>
</head>

<body>
  <form action="" method="POST" enctype="multipart/form-data">
    <input type="file" name="userFile" id="userFile"><br>
    <input type="submit" name="upload_btn" value="upload">
  </form>
  <script type="text/javascript">
    document.getElementById("userFile").onchange = function(e) {
      alert(this.value);
      this.value = null;
    }
  </script>
</body>

</html>

Explanation:

• The onchange event handler is used to handle any change in file selection event.
• The onchange event is triggered only when the value of an element is changed. So, when we select the same file using the input field the event will not be triggered. To overcome this, I set this.value = null; at the end of the onchange event function. It sets the file path of the selected file to null. Thus, the onchange event is triggered even at the time of the same file selection.

just saw this now, if you are working with a list of object you can try this

 public class user
{
    public string username { get; set; }
    public string password { get; set; }
}

  List<user> userlist = new List<user>();

        userlist.Add(new user { username = "macbruno", password = "1234" });
        userlist.Add(new user { username = "james", password = "5678" });
        string myusername = "james";
        string mypassword = "23432";

  user theUser = userlist.Find(
            delegate (user thisuser)
            {
                return thisuser.username== myusername && thisuser.password == mypassword;
            }
            );

            if (theUser != null)
            {
               Dosomething();
            }
            else
            {
                DoSomethingElse();

            }

Many of the Python directory functions are in the os.path module.

import os
os.path.isdir(d)

Multiline solution:

http://jsfiddle.net/zH58L/6/

<div style="display:table;width:30px;height:160px;">
    <img style="display:table-cell;width:30px;height:60px;padding:50px" src='...' />
    <div style="display:table-cell;height:30px;vertical-align:middle">
      Multiline text centered vertically
    </div>
</div>
<!-- note: img (height + 2x padding) must be equal to root div height -->

Works in all browers and ie9+

You can't.

Interfaces define contracts that other objects implement and therefore have no state that needs to be initialized.

If you have some state that needs to be initialized, you should consider using an abstract base class instead.

I'd like to add a little more detail to the explanation provided by everyone for the python 2 users. raw_input(), which, by now, you know that evaluates what ever data the user enters as a string. This means that python doesn't try to even understand the entered data again. All it will consider is that the entered data will be string, whether or not it is an actual string or int or anything.

While input() on the other hand tries to understand the data entered by the user. So the input like helloworld would even show the error as 'helloworld is undefined'.

In conclusion, for python 2, to enter a string too you need to enter it like 'helloworld' which is the common structure used in python to use strings.

If you get time as string in format such as 1441963946053 you simply could do something as following:

//String timestamp;
Long miliseconds = Long.valueOf(timestamp);
Timestamp ti = new Timestamp(miliseconds);

I use two methods for relative sizing. I have a class called Relative with three attached properties To, WidthPercent and HeightPercent which is useful if I want an element to be a relative size of an element anywhere in the visual tree and feels less hacky than the converter approach - although use what works for you, that you're happy with.

The other approach is rather more cunning. Add a ViewBox where you want relative sizes inside, then inside that, add a Grid at width 100. Then if you add a TextBlock with width 10 inside that, it is obviously 10% of 100.

The ViewBox will scale the Grid according to whatever space it has been given, so if its the only thing on the page, then the Grid will be scaled out full width and effectively, your TextBlock is scaled to 10% of the page.

If you don't set a height on the Grid then it will shrink to fit its content, so it'll all be relatively sized. You'll have to ensure that the content doesn't get too tall, i.e. starts changing the aspect ratio of the space given to the ViewBox else it will start scaling the height as well. You can probably work around this with a Stretch of UniformToFill.

If you want to just label the data points above the bar, you could use plt.annotate()

My code:

import numpy as np
import matplotlib.pyplot as plt

n = [1,2,3,4,5,]
s = [i**2 for i in n]
line = plt.bar(n,s)
plt.xlabel('Number')
plt.ylabel("Square")

for i in range(len(s)):
    plt.annotate(str(s[i]), xy=(n[i],s[i]), ha='center', va='bottom')

plt.show()

By specifying a horizontal and vertical alignment of 'center' and 'bottom' respectively one can get centered annotations.

Straight from the horse's mouth:

If you prefer to have dict-like view of the attributes, you can use the standard Python idiom, vars():

>>> parser = argparse.ArgumentParser()
>>> parser.add_argument('--foo')
>>> args = parser.parse_args(['--foo', 'BAR'])
>>> vars(args)
{'foo': 'BAR'}

— The Python Standard Library, 16.4.4.6. The Namespace object

You can put custom image in radiobutton like normal button. for that create one XML file in drawable folder e.g

<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/sub_screens_aus_hl" 
    android:state_pressed="true"/>  
<item android:drawable="@drawable/sub_screens_aus" 
    android:state_checked="true"/>  
<item android:drawable="@drawable/sub_screens_aus" 
    android:state_focused="true" />
<item android:drawable="@drawable/sub_screens_aus_dis" />  
</selector> 

Here you can use 3 different images for radiobutton

and use this file to RadioButton like:

android:button="@drawable/aus"
android:layout_height="120dp"
android:layout_width="wrap_content" 

Have a look at this sample:

public class A {
  //statements
}

public class B extends A {
  public void foo() { }
}

A a=new B();

//To execute **foo()** method.

((B)a).foo();

Internally, getters and setters are just methods. When C# compiles, it generates methods for your getters and setters like this, for example:

public int get_MyProperty() { ... }
public void set_MyProperty(int value) { ... }

C# allows you to declare these methods using a short-hand syntax. The line below will be compiled into the methods above when you build your application.

public int MyProperty { get; set; }

or

private int myProperty;
public int MyProperty 
{ 
    get { return myProperty; }
    set { myProperty = value; } // value is an implicit parameter containing the value being assigned to the property.
}

A "one-liner" using deconstruction and Linq to get "n [biggest unit of time] ago" :

TimeSpan timeSpan = DateTime.Now - new DateTime(1234, 5, 6, 7, 8, 9);

(string unit, int value) = new Dictionary<string, int>
{
    {"year(s)", (int)(timeSpan.TotalDays / 365.25)}, //https://en.wikipedia.org/wiki/Year#Intercalation
    {"month(s)", (int)(timeSpan.TotalDays / 29.53)}, //https://en.wikipedia.org/wiki/Month
    {"day(s)", (int)timeSpan.TotalDays},
    {"hour(s)", (int)timeSpan.TotalHours},
    {"minute(s)", (int)timeSpan.TotalMinutes},
    {"second(s)", (int)timeSpan.TotalSeconds},
    {"millisecond(s)", (int)timeSpan.TotalMilliseconds}
}.First(kvp => kvp.Value > 0);

Console.WriteLine($"{value} {unit} ago");

You get 786 year(s) ago

With the current year and month, like

TimeSpan timeSpan = DateTime.Now - new DateTime(2020, 12, 6, 7, 8, 9);

you get 4 day(s) ago

With the actual date, like

TimeSpan timeSpan = DateTime.Now - DateTime.Now.Date;

you get 9 hour(s) ago

To strip any whitespace, you can use a regular expression

$str=preg_replace('/\s+/', '', $str);

See also this answer for something which can handle whitespace in UTF-8 strings.

This is one possible solution although not very clean:

1. Make the property you need to expose to BAL & DAL internal
2. Mark BAL.dll & DAL.dll Internal Visible in assemblyinfo.cs

public class Person
{
    public Person(int id)
    {
         this.Id=id;
    }

    public string Name { get;  set; }
    public int Id { get; internal set; }
    public int Age { get; set; }
}

AssemblyInfo.cs for Entities.dll

[assembly: InternalsVisibleTo("DAL"), InternalsVisibleTo("BAL")]

That way all your internals will be visible to DAL & BAL. This may not be desirable but I'm just suggesting one possible solution.

As mentioned you can use:

overflow: scroll;

If you only want the scroll bar to appear when necessary, you can use the "auto" option:

overflow: auto;

I don't think you should be using the "float" property with "overflow", but I'd have to try out your example first.

The "Premature end of script headers" error message is probably the most loathed and common error message you'll find. What the error actually means, is that the script stopped for whatever reason before it returned any output to the web server. A common cause of this for script writers is to fail to set a content type before printing output code. In Perl for example, before printing any HTML it is necessary to tell the Perl script to set the content type to text/html, this is done by sending a header, like so:

print "Content-type: text/html\n\n";

puttygen supports exporting your private key to an OpenSSH compatible format. You can then use OpenSSH tools to recreate the public key.

1. Open PuttyGen
2. Click Load
3. Load your private key
4. Go to Conversions->Export OpenSSH and export your private key
5. Copy your private key to ~/.ssh/id_dsa (or id_rsa).

6. Create the RFC 4716 version of the public key using ssh-keygen

   ssh-keygen -e -f ~/.ssh/id_dsa > ~/.ssh/id_dsa_com.pub
   

7. Convert the RFC 4716 version of the public key to the OpenSSH format:

   ssh-keygen -i -f ~/.ssh/id_dsa_com.pub > ~/.ssh/id_dsa.pub
   

See this and this for more information.

And also Codepen sample available here: http://codepen.io/hayatbiralem/pen/KpzjOL

No needs plugin. It uses just a little css and jquery.

Here's a sample tabs markup:

<ul class="nav nav-tabs nav-tabs-responsive">
    <li class="active">
        <a href="#tab1" data-toggle="tab">
            <span class="text">Tab 1</span>
        </a>
    </li>
    <li class="next">
        <a href="#tab2" data-toggle="tab">
            <span class="text">Tab 2</span>
        </a>
    </li>
    <li>
        <a href="#tab3" data-toggle="tab">
            <span class="text">Tab 3</span>
        </a>
    </li>
    ...
</ul>

.. and jQuery codes are also here:

(function($) {

  'use strict';

  $(document).on('show.bs.tab', '.nav-tabs-responsive [data-toggle="tab"]', function(e) {
    var $target = $(e.target);
    var $tabs = $target.closest('.nav-tabs-responsive');
    var $current = $target.closest('li');
    var $parent = $current.closest('li.dropdown');
        $current = $parent.length > 0 ? $parent : $current;
    var $next = $current.next();
    var $prev = $current.prev();
    var updateDropdownMenu = function($el, position){
      $el
        .find('.dropdown-menu')
        .removeClass('pull-xs-left pull-xs-center pull-xs-right')
        .addClass( 'pull-xs-' + position );
    };

    $tabs.find('>li').removeClass('next prev');
    $prev.addClass('prev');
    $next.addClass('next');

    updateDropdownMenu( $prev, 'left' );
    updateDropdownMenu( $current, 'center' );
    updateDropdownMenu( $next, 'right' );
  });

})(jQuery);

With BS 4, you can also use the sizing, and apply w-100 so that the button can occupy the complete width of the parent container.

What type is the collection? If it's List, you can use the helpful "RemoveAll":

int cnt = workspace.RoleAssignments
                      .RemoveAll(spa => spa.Member.Name == shortName)

(This works in .NET 2.0. Of course, if you don't have the newer compiler, you'll have to use "delegate (SPRoleAssignment spa) { return spa.Member.Name == shortName; }" instead of the nice lambda syntax.)

Another approach if it's not a List, but still an ICollection:

   var toRemove = workspace.RoleAssignments
                              .FirstOrDefault(spa => spa.Member.Name == shortName)
   if (toRemove != null) workspace.RoleAssignments.Remove(toRemove);

This requires the Enumerable extension methods. (You can copy the Mono ones in, if you are stuck on .NET 2.0). If it's some custom collection that cannot take an item, but MUST take an index, some of the other Enumerable methods, such as Select, pass in the integer index for you.

Prefix you literal with 0b like in

int i = 0b11111111;

See here.

Try to use single quotes (') to avoid shell escaping of your string. Remember that the expression needs to match the whole path, i.e. needs to look like:

 find . -regex '\./[a-f0-9-]*.jpg'

Apart from that, it seems that my find (GNU 4.4.2) only knows basic regular expressions, especially not the {36} syntax. I think you'll have to make do without it.

You can do this:

app-routing-modules.ts:

import { NgModule                  }    from '@angular/core';
import { RouterModule, Routes      }    from '@angular/router';
import { PowerBoosterComponent     }    from './component/power-booster.component';


export const routes: Routes = [
  { path:  'pipeexamples',component: PowerBoosterComponent, 
data:{  name:'shubham' } },
    ];
    @NgModule({
      imports: [ RouterModule.forRoot(routes) ],
      exports: [ RouterModule ]
    })
    export class AppRoutingModule {}

In this above route, I want to send data via a pipeexamples path to PowerBoosterComponent.So now I can receive this data in PowerBoosterComponent like this:

power-booster-component.ts

import { Component, OnInit } from '@angular/core';
import { Router, ActivatedRoute, Params, Data } from '@angular/router';

@Component({
  selector: 'power-booster',
  template: `
    <h2>Power Booster</h2>`
})

export class PowerBoosterComponent implements OnInit {
  constructor(
    private route: ActivatedRoute,
    private router: Router

  ) { }
  ngOnInit() {
    //this.route.snapshot.data['name']
    console.log("Data via params: ",this.route.snapshot.data['name']);
  }
}

So you can get the data by this.route.snapshot.data['name'].

A simple way is as follows:

def count_letters(word, char):
    return word.count(char)

Or, there's another way count each element directly:

from collections import Counter
Counter('banana')

Of course, you can specify one element, e.g.

Counter('banana')['a']

The reason you are getting the the IOException is because you are not catching the IOException of your countLines method. You'll want to do something like this:

public static void main(String[] args) {
  int lines = 0;  

  // TODO - Need to get the filename to populate sFileName.  Could
  // come from the command line arguments.

   try {
       lines = LineCounter.countLines(sFileName);
    }
    catch(IOException ex){
        System.out.println (ex.toString());
        System.out.println("Could not find file " + sFileName);
    }

   if(lines > 0) {
     // Do rest of program.
   }
}

@RequestBody : Annotation indicating a method parameter should be bound to the body of the HTTP request.

For example:

@RequestMapping(path = "/something", method = RequestMethod.PUT)
public void handle(@RequestBody String body, Writer writer) throws IOException {
    writer.write(body);
}

@ResponseBody annotation can be put on a method and indicates that the return type should be written straight to the HTTP response body (and not placed in a Model, or interpreted as a view name).

For example:

@RequestMapping(path = "/something", method = RequestMethod.PUT)
public  @ResponseBody String helloWorld() {
    return "Hello World";
}  

Alternatively, we can use @RestController annotation in place of @Controller annotation. This will remove the need to using @ResponseBody.

Two additional ideas, if you want to check if a device is root capable from your app:

1. Check for the existing of the 'su' binary: run "which su" from Runtime.getRuntime().exec()
2. Look for the SuperUser.apk in /system/app/Superuser.apk location

While you can't inform JavaScript the language about types, you can inform your IDE about them, so you get much more useful autocompletion.

Here are two ways to do that:

1. Use JSDoc, a system for documenting JavaScript code in comments. In particular, you'll need the @param directive:

   /**
    * @param {Date} myDate - The date
    * @param {string} myString - The string
    */
   function myFunction(myDate, myString) {
     // ...
   }
   

   You can also use JSDoc to define custom types and specify those in @param directives, but note that JSDoc won't do any type checking; it's only a documentation tool. To check types defined in JSDoc, look into TypeScript, which can parse JSDoc tags.

2. Use type hinting by specifying the type right before the parameter in a
   /* comment */:

   

   This is a pretty widespread technique, used by ReactJS for instance. Very handy for parameters of callbacks passed to 3rd party libraries.

TypeScript

For actual type checking, the closest solution is to use TypeScript, a (mostly) superset of JavaScript. Here's TypeScript in 5 minutes.

This is easier to do if you convert your matrix to a data frame using as.data.frame(). In that case the previous answers (using subset or m$three) will work, otherwise they will not.

To perform the operation on a matrix, you can define a column by name:

m[m[, "three"] == 11,]

Or by number:

m[m[,3] == 11,]

Note that if only one row matches, the result is an integer vector, not a matrix.

Yes, You can add

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

in your source code's first line.

You can read more details here https://www.python.org/dev/peps/pep-0263/

I suspect you want to check that it's after 11pm or before 7am:

select *
from MyTable
where CAST(Created as time) >= '23:00:00' 
   or CAST(Created as time) < '07:00:00'

I posted something similar here

From Joachim's answer, from Dianne Hackborn:

http://groups.google.com/group/android-developers/browse_thread/thread/d2a5c203dad6ec42

I ended up just using:

FragmentManager fm = getActivity().getSupportFragmentManager();
for(int i = 0; i < fm.getBackStackEntryCount(); ++i) {    
    fm.popBackStack();
}

But could equally have used something like:

((AppCompatActivity)getContext()).getSupportFragmentManager().popBackStack(String name, FragmentManager.POP_BACK_STACK_INCLUSIVE)

Which will pop all states up to the named one. You can then just replace the fragment with what you want

on linux try: pkill node

on windows:

Taskkill /IM node.exe /F

or

from subprocess import call

call(['taskkill', '/IM', 'node.exe', '/F'])

One other solution can be:

public int longToInt(Long longVariable)
{
    try { 
            return Integer.valueOf(longVariable.toString()); 
        } catch(IllegalArgumentException e) { 
               Log.e(e.printstackstrace()); 
        }
}

I have tried this for cases where the client is doing a POST and the server DB understands only Integers while the client has a Long.

All other answers don't quite solve the issue. They print the date formatted as mm/dd/yyyy but the question was regarding MM/dd/yyyy. Notice the subtle difference? MM indicates that a leading zero must pad the month if the month is a single digit, thus having it always be a double digit number.

i.e. whereas mm/dd would be 3/31, MM/dd would be 03/31.

I've created a simple function to achieve this. Notice that the same padding is applied not only to the month but also to the day of the month, which in fact makes this MM/DD/yyyy:

function getFormattedDate(date) {_x000D_
  var year = date.getFullYear();_x000D_
_x000D_
  var month = (1 + date.getMonth()).toString();_x000D_
  month = month.length > 1 ? month : '0' + month;_x000D_
_x000D_
  var day = date.getDate().toString();_x000D_
  day = day.length > 1 ? day : '0' + day;_x000D_
  _x000D_
  return month + '/' + day + '/' + year;_x000D_
}

Update for ES2017 using String.padStart(), supported by all major browsers except IE.

function getFormattedDate(date) {_x000D_
    let year = date.getFullYear();_x000D_
    let month = (1 + date.getMonth()).toString().padStart(2, '0');_x000D_
    let day = date.getDate().toString().padStart(2, '0');_x000D_
  _x000D_
    return month + '/' + day + '/' + year;_x000D_
}

Dereferencing a pointer means getting the value that is stored in the memory location pointed by the pointer. The operator * is used to do this, and is called the dereferencing operator.

int a = 10;
int* ptr = &a;

printf("%d", *ptr); // With *ptr I'm dereferencing the pointer. 
                    // Which means, I am asking the value pointed at by the pointer.
                    // ptr is pointing to the location in memory of the variable a.
                    // In a's location, we have 10. So, dereferencing gives this value.

// Since we have indirect control over a's location, we can modify its content using the pointer. This is an indirect way to access a.

 *ptr = 20;         // Now a's content is no longer 10, and has been modified to 20.

These days, the most popular (and very simple) option is the ElementTree API, which has been included in the standard library since Python 2.5.

The available options for that are:

• ElementTree (Basic, pure-Python implementation of ElementTree. Part of the standard library since 2.5)
• cElementTree (Optimized C implementation of ElementTree. Also offered in the standard library since 2.5)
• LXML (Based on libxml2. Offers a rich superset of the ElementTree API as well XPath, CSS Selectors, and more)

Here's an example of how to generate your example document using the in-stdlib cElementTree:

import xml.etree.cElementTree as ET

root = ET.Element("root")
doc = ET.SubElement(root, "doc")

ET.SubElement(doc, "field1", name="blah").text = "some value1"
ET.SubElement(doc, "field2", name="asdfasd").text = "some vlaue2"

tree = ET.ElementTree(root)
tree.write("filename.xml")

I've tested it and it works, but I'm assuming whitespace isn't significant. If you need "prettyprint" indentation, let me know and I'll look up how to do that. (It may be an LXML-specific option. I don't use the stdlib implementation much)

For further reading, here are some useful links:

• API docs for the implementation in the Python standard library
• Introductory Tutorial (From the original author's site)
• LXML etree tutorial. (With example code for loading the best available option from all major ElementTree implementations)

As a final note, either cElementTree or LXML should be fast enough for all your needs (both are optimized C code), but in the event you're in a situation where you need to squeeze out every last bit of performance, the benchmarks on the LXML site indicate that:

• LXML clearly wins for serializing (generating) XML
• As a side-effect of implementing proper parent traversal, LXML is a bit slower than cElementTree for parsing.

When we have to send multiple trigger parameters to jenkins job, the following commands works.

curl -X POST -i -u "auto_user":"xxxauthentication_tokenxxx" "JENKINS_URL/view/tests/job/helloworld/buildWithParameters?param1=162&param2=store"

Ok, solved my problem, if anyone is passing by here is the answer:

Just had to add left: 0, and top: 0, to the styles, and yes, I'm tired.

position: 'absolute',
left:     0,
top:      0,

Here is Blake's excellent answer as an extension method. Add this to your project and the calls in the question will work as expected.
Meaning it is used like MyNullableDateTime.ToString("dd/MM/yyyy"), with the same output as MyDateTime.ToString("dd/MM/yyyy"), except that the value will be "N/A" if the DateTime is null.

public static string ToString(this DateTime? date, string format)
{
    return date != null ? date.Value.ToString(format) : "N/A";
}

I ended up just making a short and sweet fsize function(note, no error checking)

int fsize(FILE *fp){
    int prev=ftell(fp);
    fseek(fp, 0L, SEEK_END);
    int sz=ftell(fp);
    fseek(fp,prev,SEEK_SET); //go back to where we were
    return sz;
}

It's kind of silly that the standard C library doesn't have such a function, but I can see why it'd be difficult as not every "file" has a size(for instance /dev/null)

What worked for me :

  $where = '';
   /* $this->db->like('ust.title',$query_data['search'])
        ->or_like('usr.f_name',$query_data['search'])
        ->or_like('usr.l_name',$query_data['search']);*/
        $where .= "(ust.title like '%".$query_data['search']."%'";
        $where .= " or usr.f_name like '%".$query_data['search']."%'";
        $where .= "or usr.l_name like '%".$query_data['search']."%')";
        $this->db->where($where);



$datas = $this->db->join(TBL_USERS.' AS usr','ust.user_id=usr.id')
            ->where_in('ust.id', $blog_list) 
            ->select('ust.*,usr.f_name as f_name,usr.email as email,usr.avatar as avatar, usr.sex as sex')
            ->get_where(TBL_GURU_BLOG.' AS ust',[
                'ust.deleted_at'     =>  NULL,
                'ust.status'     =>  1,
            ]); 

I have to do this to create a query like this :

SELECT `ust`.*, `usr`.`f_name` as `f_name`, `usr`.`email` as `email`, `usr`.`avatar` as `avatar`, `usr`.`sex` as `sex` FROM `blog` AS `ust` JOIN `users` AS `usr` ON `ust`.`user_id`=`usr`.`id` WHERE (`ust`.`title` LIKE '%mer%' ESCAPE '!' OR  `usr`.`f_name` LIKE '%lok%' ESCAPE '!' OR  `usr`.`l_name` LIKE '%mer%' ESCAPE '!') AND `ust`.`id` IN('36', '37', '38') AND `ust`.`deleted_at` IS NULL AND `ust`.`status` = 1 ;

Suggestion 1

When you add an object to $stateProvider.state that object is then passed with the state. So you can add additional properties which you can read later on when needed.

Example route configuration

$stateProvider
.state('public', {
    abstract: true,
    module: 'public'
})
.state('public.login', {
    url: '/login',
    module: 'public'
})
.state('tool', {
    abstract: true,
    module: 'private'
})
.state('tool.suggestions', {
    url: '/suggestions',
    module: 'private'
});

The $stateChangeStart event gives you acces to the toState and fromState objects. These state objects will contain the configuration properties.

Example check for the custom module property

$rootScope.$on('$stateChangeStart', function(e, toState, toParams, fromState, fromParams) {
    if (toState.module === 'private' && !$cookies.Session) {
        // If logged out and transitioning to a logged in page:
        e.preventDefault();
        $state.go('public.login');
    } else if (toState.module === 'public' && $cookies.Session) {
        // If logged in and transitioning to a logged out page:
        e.preventDefault();
        $state.go('tool.suggestions');
    };
});

I didn't change the logic of the cookies because I think that is out of scope for your question.

Suggestion 2

You can create a Helper to get you this to work more modular.

Value publicStates

myApp.value('publicStates', function(){
    return {
      module: 'public',
      routes: [{
        name: 'login', 
        config: { 
          url: '/login'
        }
      }]
    };
});

Value privateStates

myApp.value('privateStates', function(){
    return {
      module: 'private',
      routes: [{
        name: 'suggestions', 
        config: { 
          url: '/suggestions'
        }
      }]
    };
});

The Helper

myApp.provider('stateshelperConfig', function () {
  this.config = {
    // These are the properties we need to set
    // $stateProvider: undefined
    process: function (stateConfigs){
      var module = stateConfigs.module;
      $stateProvider = this.$stateProvider;
      $stateProvider.state(module, {
        abstract: true,
        module: module
      });
      angular.forEach(stateConfigs, function (route){
        route.config.module = module;
        $stateProvider.state(module + route.name, route.config);
      });
    }
  };

  this.$get = function () {
    return {
      config: this.config
    };
  };
});

Now you can use the helper to add the state configuration to your state configuration.

myApp.config(['$stateProvider', '$urlRouterProvider', 
    'stateshelperConfigProvider', 'publicStates', 'privateStates',
  function ($stateProvider, $urlRouterProvider, helper, publicStates, privateStates) {
    helper.config.$stateProvider = $stateProvider;
    helper.process(publicStates);
    helper.process(privateStates);
}]);

This way you can abstract the repeated code, and come up with a more modular solution.

Note: the code above isn't tested

I fixed it with Datejs

This is alerting the first day:

var fd = Date.today().clearTime().moveToFirstDayOfMonth();
var firstday = fd.toString("MM/dd/yyyy");
alert(firstday);

This is for the last day:

var ld = Date.today().clearTime().moveToLastDayOfMonth();
var lastday = ld.toString("MM/dd/yyyy");
alert(lastday);

Swift 4

You can use Async Function for these situations. When you use DispatchGroup(),Sometimes deadlock may be occures.

var a: Int?
@objc func myFunction(completion:@escaping (Bool) -> () ) {

    DispatchQueue.main.async {
        let b: Int = 3
        a = b
        completion(true)
    }

}

override func viewDidLoad() {
    super.viewDidLoad()

    myFunction { (status) in
        if status {
            print(self.a!)
        }
    }
}

Late to the party, but the tsbox package is designed to perform conversions like this. To convert your data into a ts-object, you can do:

dta <- data.frame(
  Dates = c("3/14/2013", "3/15/2013", "3/18/2013", "3/19/2013"),
  Bajaj_close = c(1854.8, 1850.3, 1812.1, 1835.9),
  Hero_close = c(1669.1, 1684.45, 1690.5, 1645.6)
)

dta
#>       Dates Bajaj_close Hero_close
#> 1 3/14/2013      1854.8    1669.10
#> 2 3/15/2013      1850.3    1684.45
#> 3 3/18/2013      1812.1    1690.50
#> 4 3/19/2013      1835.9    1645.60

library(tsbox)
ts_ts(ts_long(dta))
#> Time Series:
#> Start = 2013.1971293045 
#> End = 2013.21081883954 
#> Frequency = 365.2425 
#>          Bajaj_close Hero_close
#> 2013.197      1854.8    1669.10
#> 2013.200      1850.3    1684.45
#> 2013.203          NA         NA
#> 2013.205          NA         NA
#> 2013.208      1812.1    1690.50
#> 2013.211      1835.9    1645.60

It automatically parses the dates, detects the frequency and makes the missing values at the weekends explicit. With ts_<class>, you can convert the data to any other time series class.

Wasim's answer a few posts up from here works as advertised:

I was in need of copying the data from one workbook to another using VBA. The requirement was as mentioned below 1. On pressing an Active X button open the dialogue to select the file from which the data needs to be copied. 2. On clicking OK the value should get copied from a cell / range to currently working workbook.

I did not want to use the open function because it opens the workbook which will be annoying

Below is the code that I wrote in the VBA. Any improvement or new alternative is welcome.

"Best" is a partially subjective decision. Use tuples for small return sets in the general case where an immutable is acceptable. A tuple is always preferable to a list when mutability is not a requirement.

For more complex return values, or for the case where formality is valuable (i.e. high value code) a named tuple is better. For the most complex case an object is usually best. However, it's really the situation that matters. If it makes sense to return an object because that is what you naturally have at the end of the function (e.g. Factory pattern) then return the object.

As the wise man said:

Premature optimization is the root of all evil (or at least most of it) in programming.

This will do the trick. Although it could be improved to ignore attributes that are now irrelevant.

Plugin:

(function($){
  $.fn.changeType = function(type) {  
    return this.each(function(i, elm) {
        var newElm = $("<input type=\""+type+"\" />");
        for(var iAttr = 0; iAttr < elm.attributes.length; iAttr++) {
            var attribute = elm.attributes[iAttr].name;
            if(attribute === "type") {
                continue;
            }
            newElm.attr(attribute, elm.attributes[iAttr].value);
        }
        $(elm).replaceWith(newElm);
    });
  };
})(jQuery);

Usage:

$(":submit").changeType("checkbox");

A very short answer: Given a fixed budget you will achieve better performing java application than a C++ application (ROI considerations) In addition Java platform has more decent profilers, that will help you pinpoint your hotspots more quickly

There's also the Java 7 solution, using the new(ish) Path abstraction:

Path fileToDeletePath = Paths.get("fileToDelete_jdk7.txt");
Files.delete(fileToDeletePath);

Hope this helps.

The usual error is one tries to put Content-Type: {multipart/form-data} into the header of the post request. That will fail, it is best to let Postman do it for you. For example:

Fails If In Header

Works

Check this link . You were missing . before myButton. It was a small error. :)

.myButton{
    background:url(./images/but.png) no-repeat;
    cursor:pointer;
    border:none;
    width:100px;
    height:100px;
}

.myButton:active  /* use Dot here */
{   
    background:url(./images/but2.png) no-repeat;
}

Simply do :

int index = List.FindIndex(your condition);

E.g.

int index = cars.FindIndex(c => c.ID == 150);

The Dim keyword is optional, when we are using it with modifiers- Public, Protected, Friend, Protected Friend,Private,Shared,Shadows,Static,ReadOnly etc. e.g. - Static nTotal As Integer

For reference type, we have to use new keyword to create the new instance of the class or structure. e.g. Dim lblTop As New System.Windows.Forms.Label.

Dim statement can be used with out a datatype when you set Option Infer to On. In that case the compiler infers the data type of a variable from the type of its initialization expression. Example :

Option Infer On

Module SampleMod

Sub Main()

 Dim nExpVar = 5

The above statement is equivalent to- Dim nExpVar As Integer

"+" does not mutate the list

.append() mutates the old list

$criteria = new \Doctrine\Common\Collections\Criteria();
    $criteria->where($criteria->expr()->gt('id', 'id'))
        ->setMaxResults(1)
        ->orderBy(array("id" => $criteria::DESC));

$results = $articlesRepo->matching($criteria);

The simplest that helped me:

rm -rf _dir_in_question_
svn up

If you have changes in the problematic dir, then this is not a good solution for you.

The first version will add a new KeyValuePair to the dictionary, throwing if key is already in the dictionary. The second, using the indexer, will add a new pair if the key doesn't exist, but overwrite the value of the key if it already exists in the dictionary.

IDictionary<string, string> strings = new Dictionary<string, string>();

strings["foo"] = "bar";          //strings["foo"] == "bar"
strings["foo"] = string.Empty;   //strings["foo"] == string.empty
strings.Add("foo", "bar");       //throws
