HTTP Basic + HTTPS is one common method.

Try this:

require 'open-uri'
open('image.png', 'wb') do |file|
  file << open('http://example.com/image.png').read
end

For the record:

"Data at the root level is invalid" means that you have attempted to parse something that is not an XML document. It doesn't even start to look like an XML document. It usually means just what you found: you're parsing something like the string "C:\inetpub\wwwroot\mysite\officelist.xml".

I came across the same problem. I properly installed the MYSQL Workbench 6.x, but faced the connection as below:

I did a bit R&D on this and found that MySQL service in service.msc is not present. To achieve this I created a new connection in MySQL Workbench then manually configured the MySQL Database Server in "System Profile" (see the below picture).

You also need to install MySQL Database Server and set a configuration file path for my.ini. Now at last test the connection (make sure MySQL service is running in services.msc).

Process GET parameters

The <f:viewParam> manages the setting, conversion and validation of GET parameters. It's like the <h:inputText>, but then for GET parameters.

The following example

<f:metadata>
    <f:viewParam name="id" value="#{bean.id}" />
</f:metadata>

does basically the following:

• Get the request parameter value by name id.
• Convert and validate it if necessary (you can use required, validator and converter attributes and nest a <f:converter> and <f:validator> in it like as with <h:inputText>)
• If conversion and validation succeeds, then set it as a bean property represented by #{bean.id} value, or if the value attribute is absent, then set it as request attribtue on name id so that it's available by #{id} in the view.

So when you open the page as foo.xhtml?id=10 then the parameter value 10 get set in the bean this way, right before the view is rendered.

As to validation, the following example sets the param to required="true" and allows only values between 10 and 20. Any validation failure will result in a message being displayed.

<f:metadata>
    <f:viewParam id="id" name="id" value="#{bean.id}" required="true">
        <f:validateLongRange minimum="10" maximum="20" />
    </f:viewParam>
</f:metadata>
<h:message for="id" />

Performing business action on GET parameters

You can use the <f:viewAction> for this.

<f:metadata>
    <f:viewParam id="id" name="id" value="#{bean.id}" required="true">
        <f:validateLongRange minimum="10" maximum="20" />
    </f:viewParam>
    <f:viewAction action="#{bean.onload}" />
</f:metadata>
<h:message for="id" />

with

public void onload() {
    // ...
}

The <f:viewAction> is however new since JSF 2.2 (the <f:viewParam> already exists since JSF 2.0). If you can't upgrade, then your best bet is using <f:event> instead.

<f:event type="preRenderView" listener="#{bean.onload}" />

This is however invoked on every request. You need to explicitly check if the request isn't a postback:

public void onload() {
    if (!FacesContext.getCurrentInstance().isPostback()) {
        // ...
    }
}

When you would like to skip "Conversion/Validation failed" cases as well, then do as follows:

public void onload() {
    FacesContext facesContext = FacesContext.getCurrentInstance();
    if (!facesContext.isPostback() && !facesContext.isValidationFailed()) {
        // ...
    }
}

Using <f:event> this way is in essence a workaround/hack, that's exactly why the <f:viewAction> was introduced in JSF 2.2.

Pass view parameters to next view

You can "pass-through" the view parameters in navigation links by setting includeViewParams attribute to true or by adding includeViewParams=true request parameter.

<h:link outcome="next" includeViewParams="true">
<!-- Or -->
<h:link outcome="next?includeViewParams=true">

which generates with the above <f:metadata> example basically the following link

<a href="next.xhtml?id=10">

with the original parameter value.

This approach only requires that next.xhtml has also a <f:viewParam> on the very same parameter, otherwise it won't be passed through.

Use GET forms in JSF

The <f:viewParam> can also be used in combination with "plain HTML" GET forms.

<f:metadata>
    <f:viewParam id="query" name="query" value="#{bean.query}" />
    <f:viewAction action="#{bean.search}" />
</f:metadata>
...
<form>
    <label for="query">Query</label>
    <input type="text" name="query" value="#{empty bean.query ? param.query : bean.query}" />
    <input type="submit" value="Search" />
    <h:message for="query" />
</form>
...
<h:dataTable value="#{bean.results}" var="result" rendered="#{not empty bean.results}">
     ...
</h:dataTable>

With basically this @RequestScoped bean:

private String query;
private List<Result> results;

public void search() {
    results = service.search(query);
}

Note that the <h:message> is for the <f:viewParam>, not the plain HTML <input type="text">! Also note that the input value displays #{param.query} when #{bean.query} is empty, because the submitted value would otherwise not show up at all when there's a validation or conversion error. Please note that this construct is invalid for JSF input components (it is doing that "under the covers" already).

I just wrote this cos none of the answers already here were simple enough. You can replace the hardcoded 128 for whatever you want or base them off the size of the original image. All i wanted was to rescale the image into a 128x128 image, keeping the aspect ratio and centering the result in the new image.

    private Bitmap CreateLargeIconForImage(Bitmap src)
    {
        Bitmap bmp = new Bitmap(128, 128);
        Graphics g = Graphics.FromImage(bmp);

        float scale = Math.Max((float)src.Width / 128.0f, (float)src.Height / 128.0f);
        PointF p = new PointF(128.0f - ((float)src.Width / scale), 128.0f - ((float)src.Height / scale));
        SizeF size = new SizeF((float)src.Width / scale, (float)src.Height / scale);

        g.DrawImage(src, new RectangleF(p, size));

        return bmp;
    }

I tried the below and it worked well,

Install Dimensions Data Model and OLE DB Access

and follow the below steps in excel

Data->Get External Data ->From Other sources -> From Data Connection Wizard -> Other/Advanced-> SPSS MR DM-2 OLE DB Provider-> Metadata type as SPSS File(SAV)-> SPSS data file in Metadata Location->Finish

I had the same problem and found a very elegant solution for a Pager Class from

http://blogs.taiga.nl/martijn/2008/08/27/paging-with-aspnet-mvc/

In your controller the call looks like:

return View(partnerList.ToPagedList(currentPageIndex, pageSize));

and in your view:

<div class="pager">
    Seite: <%= Html.Pager(ViewData.Model.PageSize, 
                          ViewData.Model.PageNumber,
                          ViewData.Model.TotalItemCount)%>
</div>

I just think of Rebuild as performing the Clean first followed by the Build. Perhaps I am wrong ... comments?

OSX Sierra, Python 2.7, Graphviz 2.38

Using pip install graphviz and conda install graphviz BOTH resolves the problem.

pip only gets path problem same as yours and conda only gets import error.

Would the use of <caption> be allowed?

<ul>
  <caption> Title of List </caption>
  <li> Item 1 </li>
  <li> Item 2 </li>
</ul>

Accessing a single row

//Result as an Object
$result = $this->db->select('age')->from('my_users_table')->where('id', '3')->limit(1)->get()->row();
echo $result->age;

//Result as an Array
$result = $this->db->select('age')->from('my_users_table')->where('id', '3')->limit(1)->get()->row_array();
echo $result['age'];

The whole point of using Maps is direct access. If you know for sure that the value in a map will never be Groovy-false, then you can do this:

def mymap = [name:"Gromit", likes:"cheese", id:1234]
def key = "likes"

if(mymap[key]) {
    println mymap[key]
}

However, if the value could potentially be Groovy-false, you should use:

if(mymap.containsKey(key)) {
    println mymap[key]
}

The easiest solution, though, if you know the value isn't going to be Groovy-false (or you can ignore that), and want a default value, is like this:

def value = mymap[key] ?: "default"

All three of these solutions are significantly faster than your examples, because they don't scan the entire map for keys. They take advantage of the HashMap (or LinkedHashMap) design that makes direct key access nearly instantaneous.

Sometimes you may get "Exception in thread "main" java.lang.NoClassDefFoundError: org/codehaus/classworlds/Launcher" even after setting M2_HOME and PATH parameters correctly.

This exception is because your JDK/Java version need to be updated/installed.

In HTML:

<form onsubmit="return false">
</form>

in order to avoid refresh at all "buttons", even with onclick assigned.

Just for reference's sake. This is how to do it with JQuery (useful for instance when you cannot query by element id):

$('#iframe').get(0).contentWindow.document.body.innerHTML

Here's another way to do it: add a div in your form with a classname dropzone, and implement dropzone programmatically.

HTML :

<div id="dZUpload" class="dropzone">
      <div class="dz-default dz-message"></div>
</div>

JQuery:

$(document).ready(function () {
    Dropzone.autoDiscover = false;
    $("#dZUpload").dropzone({
        url: "hn_SimpeFileUploader.ashx",
        addRemoveLinks: true,
        success: function (file, response) {
            var imgName = response;
            file.previewElement.classList.add("dz-success");
            console.log("Successfully uploaded :" + imgName);
        },
        error: function (file, response) {
            file.previewElement.classList.add("dz-error");
        }
    });
});

Note : Disabling autoDiscover, otherwise Dropzone will try to attach twice

You can fire the event simply with

document.getElementById("elementID").onchange();

I dont know if this doesnt work on some browsers, but it should work on FF 3 and IE 7+

How about this... It only requires one iteration over the string (doesn't use strlen, which iterates over the string). When the function returns you get a pointer to the start of the trimmed string which is null terminated. The string is trimmed of spaces from the left (until the first character is found). The string is also trimmed of all trailing spaces after the last nonspace character.

char* trim(char* input) {
    char* start = input;
    while (isSpace(*start)) { //trim left
        start++;
    }

    char* ptr = start;
    char* end = start;
    while (*ptr++ != '\0') { //trim right
        if (!isSpace(*ptr)) { //only move end pointer if char isn't a space
            end = ptr;
        }
    }

    *end = '\0'; //terminate the trimmed string with a null
    return start;
}

bool isSpace(char c) {
    switch (c) {
        case ' ':
        case '\n':
        case '\t':
        case '\f':
        case '\r':
            return true;
            break;
        default:
            return false;
            break;
    }
}

Just put this code in your content div

<?php
// TO SHOW THE PAGE CONTENTS
    while ( have_posts() ) : the_post(); ?> <!--Because the_content() works only inside a WP Loop -->
        <div class="entry-content-page">
            <?php the_content(); ?> <!-- Page Content -->
        </div><!-- .entry-content-page -->

    <?php
endwhile; //resetting the page loop
wp_reset_query(); //resetting the page query
?>

try using dedicated functions from high level programming languages. JavaScript .getSeconds(); suits here:

var specifiedTime = new Date("November 02, 2017 06:00:00");
var specifiedTimeSeconds = specifiedTime.getSeconds(); 

var currentTime = new Date();
var currentTimeSeconds = currentTime.getSeconds(); 

alert(specifiedTimeSeconds-currentTimeSeconds);

Edit: After Docker 1.9, the docker network command (see below https://stackoverflow.com/a/35184695/977939) is the recommended way to achieve this.

My solution is to set up a dnsmasq on the host to have DNS record automatically updated: "A" records have the names of containers and point to the IP addresses of the containers automatically (every 10 sec). The automatic updating script is pasted here:

#!/bin/bash

# 10 seconds interval time by default
INTERVAL=${INTERVAL:-10}

# dnsmasq config directory
DNSMASQ_CONFIG=${DNSMASQ_CONFIG:-.}

# commands used in this script
DOCKER=${DOCKER:-docker}
SLEEP=${SLEEP:-sleep}
TAIL=${TAIL:-tail}

declare -A service_map

while true
do
    changed=false
    while read line
    do
        name=${line##* }
        ip=$(${DOCKER} inspect --format '{{.NetworkSettings.IPAddress}}' $name)
        if [ -z ${service_map[$name]} ] || [ ${service_map[$name]} != $ip ] # IP addr changed
        then
            service_map[$name]=$ip
            # write to file
            echo $name has a new IP Address $ip >&2
            echo "host-record=$name,$ip"  > "${DNSMASQ_CONFIG}/docker-$name"
            changed=true
        fi
    done < <(${DOCKER} ps | ${TAIL} -n +2)

    # a change of IP address occured, restart dnsmasq
    if [ $changed = true ]
    then
        systemctl restart dnsmasq
    fi

    ${SLEEP} $INTERVAL
done

Make sure your dnsmasq service is available on docker0. Then, start your container with --dns HOST_ADDRESS to use this mini dns service.

Create a Empty Guid or New Guid Using a Class...

Default value of Guid is 00000000-0000-0000-0000-000000000000

public class clsGuid  ---This is class Name
{
    public Guid MyGuid { get; set; }
}

static void Main(string[] args)
        {
            clsGuid cs = new clsGuid();   
            Console.WriteLine(cs.MyGuid); --this will give empty Guid  "00000000-0000-0000-0000-000000000000"

            cs.MyGuid = new Guid();
            Console.WriteLine(cs.MyGuid); ----this will also give empty Guid  "00000000-0000-0000-0000-000000000000"

            cs.MyGuid = Guid.NewGuid();
            Console.WriteLine(cs.MyGuid); --this way, it will give new guid  "d94828f8-7fa0-4dd0-bf91-49d81d5646af"

            Console.ReadKey(); --this line holding the output screen in console application...
        }

Other option using apache-commons:

import org.apache.commons.codec.binary.Base64;
import org.apache.commons.io.FileUtils;

...
File file = new File( "path" );
byte[] bytes = Base64.decodeBase64( "base64" );
FileUtils.writeByteArrayToFile( file, bytes );

Works perfect:

    internal static int GetDifferenceInYears(DateTime startDate)
    {
        int finalResult = 0;

        const int DaysInYear = 365;

        DateTime endDate = DateTime.Now;

        TimeSpan timeSpan = endDate - startDate;

        if (timeSpan.TotalDays > 365)
        {
            finalResult = (int)Math.Round((timeSpan.TotalDays / DaysInYear), MidpointRounding.ToEven);
        }

        return finalResult;
    }

I always prefer to use the example mentioned in Konva JS: Image Events to load images.

1. You need to have a list of image URLs as object or array, for example:

   var sources = { lion: '/assets/lion.png', monkey: '/assets/monkey.png' };

2. Define the Function definition, where it receives list of image URLs and a callback function in its arguments list, so when it finishes loading image you can start excution on your web page:

    function loadImages(sources, callback) {_x000D_
                var images = {};_x000D_
                var loadedImages = 0;_x000D_
                var numImages = 0;_x000D_
                for (var src in sources) {_x000D_
                    numImages++;_x000D_
                }_x000D_
                for (var src in sources) {_x000D_
                    images[src] = new Image();_x000D_
                    images[src].onload = function () {_x000D_
                        if (++loadedImages >= numImages) {_x000D_
                            callback(images);_x000D_
                        }_x000D_
                    };_x000D_
                    images[src].src = sources[src];_x000D_
                }_x000D_
            }

3. Lastly, you need to call the function. You can call it for example from jQuery's Document Ready

$(document).ready(function (){ loadImages(sources, buildStage); });

The below code will first get all the checkboxes present on the page, and then deselect all the checked boxes.

List<WebElement> allCheckbox = driver.findElements(By
    .xpath("//input[@type='checkbox']"));

for (WebElement ele : allCheckbox) {
    if (ele.isSelected()) {
        ele.click();
    }
}

You can use HttpPost, there are methods to add Header to the Request.

DefaultHttpClient httpclient = new DefaultHttpClient();
String url = "http://localhost";
HttpPost httpPost = new HttpPost(url);

httpPost.addHeader("header-name" , "header-value");

HttpResponse response = httpclient.execute(httpPost);

function removeAllBlankOrNull(JsonObj) {
    $.each(JsonObj, function(key, value) {
        if (value === "" || value === null) {
            delete JsonObj[key];
        } else if (typeof(value) === "object") {
            JsonObj[key] = removeAllBlankOrNull(value);
        }
    });
    return JsonObj;
}

Deletes all empty strings and null values recursively. Fiddle

And, why not unobtrusive with jQuery:

  $(function() {
    $("#unobtrusive").click(function(e) {
      e.preventDefault(); // if desired...
      // other methods to call...
    });
  });

HTML

<a id="unobtrusive" href="http://jquery.com">jquery</a>

I would just use..

try:
    float(element)
except ValueError:
    print "Not a float"

..it's simple, and it works. Note that it will still throw OverflowError if element is e.g. 1<<1024.

Another option would be a regular expression:

import re
if re.match(r'^-?\d+(?:\.\d+)$', element) is None:
    print "Not float"

If you are actually looking for the index number (and not the value) of the selected option then it would be

document.forms[0].elements["CCards"].selectedIndex 
/* You may need to change document.forms[0] to reference the correct form */

or using jQuery

$('select[name="CCards"]')[0].selectedIndex 

More easy to understand (What is Lambda actually doing):

ls2=[[0,1,'f'],[4,2,'t'],[9,4,'afsd']]

Enter with Administrator user. First, you must enable it http://www.ghacks.net/2014/11/12/how-to-enable-the-hidden-windows-10-administrator-account/

Install it from C:\Android\sdk\extras\intel\Hardware_Accelerated_Execution_Manager\intelhaxm-andoid.exe

And login with your user. It work for me.

Using ramda#pickBy you will remove all null, undefined and false values:

const obj = {a:1, b: undefined, c: null, d: 1}
R.pickBy(R.identity, obj)

As @manroe pointed out, to keep false values use isNil():

const obj = {a:1, b: undefined, c: null, d: 1, e: false}
R.pickBy(v => !R.isNil(v), obj)

Below is an example of such a query:

INSERT INTO [93275].[93276].[93277].[93278] ( [Mobile Number], [Mobile Series], [Full Name], [Full Address], [Active Date], company ) IN 'I:\For Test\90-Mobile Series.accdb
SELECT [1].[Mobile Number], [1].[Mobile Series], [1].[Full Name], [1].[Full Address], [1].[Active Date], [1].[Company Name]
FROM 1
WHERE ((([1].[Mobile Series])="93275" Or ([1].[Mobile Series])="93276")) OR ((([1].[Mobile Series])="93277"));OR ((([1].[Mobile Series])="93278"));

CSS supports text input for colors (i.e. "black" = #000000 "white" = #ffffff) So I think the helpful solution we are looking for here is how can one have PHP take the output from an HTML form text input box and have it tell CSS to use this line of text for background color.

So that when a a user types "blue" into the text field titled "what is your favorite color", they are returned a page with a blue background, or whatever color they happen to type in so long as it is recognized by CSS.

I believe Dan is on the right track, but may need to elaborate for use PHP newbies, when I try this I am returned a green screen no matter what is typed in (I even set this up as an elseif to display a white background if no data is entered in the text field, still green?

For a more aesthetic appearance :) can be:

left:-9999em; 
top:-9999em; 

position for .sNv2 .nav UL can be replaced by z-index:-1 and z-index:1 for .sNv2 .nav LI:Hover UL

You can use

value.ToString(CultureInfo.InvariantCulture)

to get exact double value without putting precision.

I prepared a function by consolidating Mark Byers' solution with Reimund and Morten Zilmer's comments (relative path and including empty directories). As a best practice, with is used in ZipFile's file construction.

The function also prepares a default zip file name with the zipped directory name and '.zip' extension. Therefore, it works with only one argument: the source directory to be zipped.

import os
import zipfile

def zip_dir(path_dir, path_file_zip=''):
if not path_file_zip:
    path_file_zip = os.path.join(
        os.path.dirname(path_dir), os.path.basename(path_dir)+'.zip')
with zipfile.ZipFile(path_file_zip, 'wb', zipfile.ZIP_DEFLATED) as zip_file:
    for root, dirs, files in os.walk(path_dir):
        for file_or_dir in files + dirs:
            zip_file.write(
                os.path.join(root, file_or_dir),
                os.path.relpath(os.path.join(root, file_or_dir),
                                os.path.join(path_dir, os.path.pardir)))

updating ipykernel did it for me. it seems arch linux's ipykernel package had been outdated for some time

just do pip install --upgrade ipykernel

You should set async = false in head. Use post/get instead of ajax.

jQuery.ajaxSetup({ async: false });

    $.post({
        url: 'api.php',
        data: 'id1=' + q + '',
        dataType: 'json',
        success: function (data) {

            id = data[0];
            vname = data[1];

        }

Atom does not have block comment by default, so I would recommend searching for atom packages by "block comment" and install the one suits to you.

I prefer https://atom.io/packages/block-comment because is has the closest keyboard shortcut to line comment and it works as i need it to, meaning it would not comment the whole line but only the selected text.

line comment: CTRL+/ block comment: CTRL+SHIFT+/ (with the plugin installed)

use -ProjectName option in Package Manager Console:

Enable-Migrations -ProjectName Toombu.DataAccess -StartUpProjectName Toombu.Web -Verbose

The same origin policy is applicable only for browser side programming languages. So if you try to post to a different server than the origin server using JavaScript, then the same origin policy comes into play but if you post directly from the form i.e. the action points to a different server like:

<form action="http://someotherserver.com">

and there is no javascript involved in posting the form, then the same origin policy is not applicable.

See wikipedia for more information

The easiest solution is to redirect the standard output. In your python program file use the following:

if __name__ == "__main__":
   sys.stdout = open('file.log', 'w')
   #sys.stdout = open('/dev/null', 'w')
   main()

Any std output (e.g. the output of print 'hi there') will be redirected to file.log or if you uncomment the second line, any output will just be suppressed.

In addition to everything else that has been said, you can call DefaultIfEmpty() before you call Single(). This will ensure that your sequence contains something and thereby averts the InvalidOperationException "Sequence contains no elements". For example:

BlogPost post = (from p in dc.BlogPosts
                 where p.BlogPostID == ID
                 select p).DefaultIfEmpty().Single();

input[type="checkbox"] {
 /* your style */
}

But this will only work for browsers except IE7 and below, for those you will have to use a class.

Tag ids must be unique. You are updating the span with ID 'ItemCostSpan' of which there are two. Give the span a class and get it using find.

    $("legend").each(function() {
        var SoftwareItem = $(this).text();
        itemCost = GetItemCost(SoftwareItem);
        $("input:checked").each(function() {               
            var Component = $(this).next("label").text();
            itemCost += GetItemCost(Component);
        });            
        $(this).find(".ItemCostSpan").text("Item Cost = $ " + itemCost);
    });

Jano's answer is the easiest way to find it.. another way would be if you click on the scheme drop down bar -> edit scheme -> arguments tab and then add NSZombieEnabled in the Environment Variables column and YES in the value column...

From the PHP manual:

<?php
$row = 1;
if (($handle = fopen("test.csv", "r")) !== FALSE) {
    while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
        $num = count($data);
        echo "<p> $num fields in line $row: <br /></p>\n";
        $row++;
        for ($c=0; $c < $num; $c++) {
            echo $data[$c] . "<br />\n";
        }
    }
    fclose($handle);
}
?>

You can use zip with * to get transpose of a matrix:

>>> A = [[ 1, 2, 3],[ 4, 5, 6]]
>>> zip(*A)
[(1, 4), (2, 5), (3, 6)]
>>> lis  = [[1,2,3], 
... [4,5,6],
... [7,8,9]]
>>> zip(*lis)
[(1, 4, 7), (2, 5, 8), (3, 6, 9)]

If you want the returned list to be a list of lists:

>>> [list(x) for x in zip(*lis)]
[[1, 4, 7], [2, 5, 8], [3, 6, 9]]
#or
>>> map(list, zip(*lis))
[[1, 4, 7], [2, 5, 8], [3, 6, 9]]

It is better to also escape SQL reserved words. For example:

function ms_escape_string($data) {
    if (!isset($data) or empty($data))
        return '';

    if (is_numeric($data))
        return $data;

    $non_displayables = array(
        '/%0[0-8bcef]/',        // URL encoded 00-08, 11, 12, 14, 15
        '/%1[0-9a-f]/',         // url encoded 16-31
        '/[\x00-\x08]/',        // 00-08
        '/\x0b/',               // 11
        '/\x0c/',               // 12
        '/[\x0e-\x1f]/',        // 14-31
        '/\27/'
    );
    foreach ($non_displayables as $regex)
        $data = preg_replace( $regex, '', $data);
    $reemplazar = array('"', "'", '=');
    $data = str_replace($reemplazar, "*", $data);
    return $data;
}

I was searching for how to undo a pull request and got here.

I was about to just git reset --hard to "a long time ago" and do a fast forward back to where I was before doing the pull request.

Besides looking here, I also asked my co-worker what he would do, and he had a typically good answer: using the example output in the first answer above:

git reset --hard 9271e6e

As with most things in Git, if you're doing it some way that's not easy, you're probably doing it wrong.

Depends on the version of PHP. For php7.0 the following commands work:
sudo apt-get install php7.0-sqlite3
then restart the Apache server:
sudo service apache2 restart

Do something like:

<?php
if ($_SERVER['SCRIPT_FILENAME'] == '<path to php include file>') {
    header('HTTP/1.0 403 Forbidden');
    exit('Forbidden');
}
?>

You have to use Promise to print or store values of element.

 var ExpectedValue:string ="AllTestings.com";
          element(by.id("xyz")).getAttribute("value").then(function (Text) {

                        expect(Text.trim()).toEqual("ExpectedValue", "Wrong page navigated");//Assertion
        console.log("Text");//Print here in Console

                    });

I see you want to do Cloning, not just copying references. In this case you can use .Select to project array members to their clones. For example, if your elements implemented IClonable you could do something like this:

var newArray = array.Skip(3).Take(5).Select(eachElement => eachElement.Clone()).ToArray();

Note: This solution requires .NET Framework 3.5.

This is ALL I needed to init mongo in PowerShell, many replies are IMO too sophisticated.

1. Install: https://www.mongodb.com/download-center#community
2. Add C:\Program Files\MongoDB\Server\3.6\bin to environmental variable "path". Notice: this version will be outdated soon.
3. Turn on new PowerShell, as it gets environmental variables on a start, then type mongod
4. Open another PowerShell window and type mongo - you have access to mongo REPL! If you don't, just repeat 4 again (known bug: https://jira.mongodb.org/browse/SERVER-32473)

Output Buffering for Web Developers, a Beginner’s Guide:

Without output buffering (the default), your HTML is sent to the browser in pieces as PHP processes through your script. With output buffering, your HTML is stored in a variable and sent to the browser as one piece at the end of your script.

Advantages of output buffering for Web developers

• Turning on output buffering alone decreases the amount of time it takes to download and render our HTML because it's not being sent to the browser in pieces as PHP processes the HTML.
• All the fancy stuff we can do with PHP strings, we can now do with our whole HTML page as one variable.
• If you've ever encountered the message "Warning: Cannot modify header information - headers already sent by (output)" while setting cookies, you'll be happy to know that output buffering is your answer.

While AngularJS allows you to get a hand on a click event (and thus a target of it) with the following syntax (note the $event argument to the setMaster function; documentation here: http://docs.angularjs.org/api/ng.directive:ngClick):

function AdminController($scope) {    
  $scope.setMaster = function(obj, $event){
    console.log($event.target);
  }
}

this is not very angular-way of solving this problem. With AngularJS the focus is on the model manipulation. One would mutate a model and let AngularJS figure out rendering.

The AngularJS-way of solving this problem (without using jQuery and without the need to pass the $event argument) would be:

<div ng-controller="AdminController">
    <ul class="list-holder">
        <li ng-repeat="section in sections" ng-class="{active : isSelected(section)}">
            <a ng-click="setMaster(section)">{{section.name}}</a>
        </li>
    </ul>
    <hr>
    {{selected | json}}
</div>

where methods in the controller would look like this:

$scope.setMaster = function(section) {
    $scope.selected = section;
}

$scope.isSelected = function(section) {
    return $scope.selected === section;
}

Here is the complete jsFiddle: http://jsfiddle.net/pkozlowski_opensource/WXJ3p/15/

This is the way how I simulate constructor in functional components using the useRef hook:

function Component(props) {
    const willMount = useRef(true);
    if (willMount.current) {
        console.log('This runs only once before rendering the component.');
        willMount.current = false;        
    }

    return (<h1>Meow world!</h1>);
}

Here is the lifecycle example:

function RenderLog(props) {
    console.log('Render log: ' + props.children);
    return (<>{props.children}</>);
}

function Component(props) {

    console.log('Body');
    const [count, setCount] = useState(0);
    const willMount = useRef(true);

    if (willMount.current) {
        console.log('First time load (it runs only once)');
        setCount(2);
        willMount.current = false;
    } else {
        console.log('Repeated load');
    }

    useEffect(() => {
        console.log('Component did mount (it runs only once)');
        return () => console.log('Component will unmount');
    }, []);

    useEffect(() => {
        console.log('Component did update');
    });

    useEffect(() => {
        console.log('Component will receive props');
    }, [count]);


    return (
        <>
        <h1>{count}</h1>
        <RenderLog>{count}</RenderLog>
        </>
    );
}

[Log] Body
[Log] First time load (it runs only once)
[Log] Body
[Log] Repeated load
[Log] Render log: 2
[Log] Component did mount (it runs only once)
[Log] Component did update
[Log] Component will receive props

Of course Class components don't have Body steps, it's not possible to make 1:1 simulation due to different concepts of functions and classes.

#include <sstream> and use the fully qualified name i.e. std::stringstream ss;

Highlight both rows in the table design view and click on the key icon, they will now be a composite primary key.

I'm not sure of your question, but only one column per table may be an IDENTITY column, not both.

I just learned this trick from a friend. Put your code inside these 2 statements and it will be commented out.

        if (isAppEnabled(context, packageName))
            context.startActivity(context.getPackageManager().getLaunchIntentForPackage(packageName));

docs explicitly state that destination directory should not exist:

The destination directory, named by dst, must not already exist; it will be created as well as missing parent directories.

I think your best bet is to os.walk the second and all consequent directories, copy2 directory and files and do additional copystat for directories. After all that's precisely what copytree does as explained in the docs. Or you could copy and copystat each directory/file and os.listdir instead of os.walk.

Your string is invalid, but assuming it was valid, you'd have to do:

var finalData = str.replace(/\\/g, "");

When you want to replace all the occurences with .replace, the first parameter must be a regex, if you supply a string, only the first occurrence will be replaced, that's why your replace wouldn't work.

The Data Export function in MySQL Workbench allows 2 of the 3 ways. There's a checkbox Skip Table Data (no-data) on the export page which allows to either dump with or without data. Just dumping the data without meta data is not supported.

Min-value will always start at zero and its nothing you can do about it. But you can change its value when user start scrolling it around.

Here I set the max-value as 64. This calculations are simple: I want the user to pick a time from 15min to 16 hours, and he picks one of every 15min to 16 hours, clear? I know, very simple :)

    SeekBar seekBar = (SeekBar) dialog.findViewById(R.id.seekBar);
    seekBar.setMax(64);

    seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
        float b;

        @Override
        public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
            float des = (float) progress / 4;
            b = des;
            hours.setText(des + " hours");

It is going to write the value of your property model.Destination

This is by design. You'll want to populate your Destination property with the value you want in your controller before returning your view.

Check file_get_contents ^{PHP Manual} return value. If the value is FALSE then it could not read the file. If the value is NULL then the function itself is disabled.

To learn more what might gone wrong with the file_get_contents operation you must enable error reporting and the display of errors to actually read them.

# Enable Error Reporting and Display:
error_reporting(~0);
ini_set('display_errors', 1);

You can get more details about the why the call is failing by checking the INI values on your server. One value the directly effects the file_get_contents function is allow_url_fopen. You can do this by running the following code. You should note, that if it reports that fopen is not allowed, then you'll have to ask your provider to change this setting on your server in order for any code that require this function to work with URLs.

<html>
    <head>        
        <title>Test File</title>
        <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false">
        </script>
    </head>
    <body>
<?php

# Enable Error Reporting and Display:
error_reporting(~0);
ini_set('display_errors', 1);

$adr = 'Sydney+NSW';
echo $adr;
$url = "http://maps.googleapis.com/maps/api/geocode/json?address=$adr&sensor=false";
echo '<p>'.$url.'</p>';

$jsonData = file_get_contents($url);

print '<p>', var_dump($jsonData), '</p>';

# Output information about allow_url_fopen:
if (ini_get('allow_url_fopen') == 1) {
    echo '<p style="color: #0A0;">fopen is allowed on this host.</p>';
} else {
    echo '<p style="color: #A00;">fopen is not allowed on this host.</p>';
}


# Decide what to do based on return value:
if ($jsonData === FALSE) {
    echo "Failed to open the URL ", htmlspecialchars($url);
} elseif ($jsonData === NULL) {
    echo "Function is disabled.";
} else {
   echo $jsonData;
}

?>
    </body>
</html>

If all of this fails, it might be due to the use of short open tags, <?. The example code in this answer has been therefore changed to make use of <?php to work correctly as this is guaranteed to work on in all version of PHP, no matter what configuration options are set. To do so for your own script, just replace <? or <?php.

To be perfectly precise, Darwin is enough. No need to import the whole Cocoa framework.

import Darwin

Of course, if you need elements from Cocoa or Foundation or other higher level frameworks, you can import them instead

What you could do is something like this (pseudocode):

<container table>
  <tr>
    <td>
      <"300px" table>
    <td>
      <fixed layout table>

Basically, split up the table into two tables and have it contained by another table.

svn merge -r 1944:1943 . should revert the changes of r1944 in your working copy. You can then review the changes in your working copy (with diff), but you'd need to commit in order to apply the revert into the repository.

Option 1 is the only good solution.

Why?

• Option 2 does the same but you repeat the column name lots of times; additionally the SQL engine doesn't immediately know that you want to check if the value is one of the values in a fixed list. However, a good SQL engine could optimize it to have equal performance like with IN. There's still the readability issue though...

• Option 3 is simply horrible performance-wise. It sends a query every loop and hammers the database with small queries. It also prevents it from using any optimizations for "value is one of those in a given list"

2> use this source code.

JArray array= (JArray)ojObject ["chats"];
int id = Convert.ToInt32(array[0].toString());

However it depends on jQuery, here is a version that has no dependencies:

HTML

<div id="sticky" class="sticky"></div>

CSS

.sticky {
  width: 100%
}

.fixed {
  position: fixed;
  top:0;
}

JS
(This uses eyelidlessness's answer for finding offsets in Vanilla JS.)

function findOffset(element) {
  var top = 0, left = 0;

  do {
    top += element.offsetTop  || 0;
    left += element.offsetLeft || 0;
    element = element.offsetParent;
  } while(element);

  return {
    top: top,
    left: left
  };
}

window.onload = function () {
  var stickyHeader = document.getElementById('sticky');
  var headerOffset = findOffset(stickyHeader);

  window.onscroll = function() {
    // body.scrollTop is deprecated and no longer available on Firefox
    var bodyScrollTop = document.documentElement.scrollTop || document.body.scrollTop;

    if (bodyScrollTop > headerOffset.top) {
      stickyHeader.classList.add('fixed');
    } else {
      stickyHeader.classList.remove('fixed');
    }
  };
};

You need to use the new operator when creating the object

Contacts.add(new Data(name, address, contact)); // Creating a new object and adding it to list - single step

or else

Data objt = new Data(name, address, contact); // Creating a new object
Contacts.add(objt); // Adding it to the list

and your constructor shouldn't contain void. Else it becomes a method in your class.

public Data(String n, String a, String c) { // Constructor has the same name as the class and no return type as such

You need an Oracle Client: http://www.oracle.com/technology/oramag/oracle/08-nov/o68odpnet.html

This uses twitter bootstrap 3.x with one css class to get labels to sit on top of the inputs. Here's a fiddle link, make sure to expand results panel wide enough to see effect.

HTML:

  <div class="row myform">
     <div class="col-md-12">
        <form name="myform" role="form" novalidate>
           <div class="form-group">
              <label class="control-label" for="fullName">Address Line</label>
              <input required type="text" name="addr" id="addr" class="form-control" placeholder="Address"/>
           </div>

           <div class="form-inline">
              <div class="form-group">
                 <label>State</label>
                 <input required type="text" name="state" id="state" class="form-control" placeholder="State"/>
              </div>

              <div class="form-group">
                 <label>ZIP</label>
                 <input required type="text" name="zip" id="zip" class="form-control" placeholder="Zip"/>
              </div>
           </div>

           <div class="form-group">
              <label class="control-label" for="country">Country</label>
              <input required type="text" name="country" id="country" class="form-control" placeholder="country"/>
           </div>
        </form>
     </div>
  </div>

CSS:

.myform input.form-control {
   display: block;  /* allows labels to sit on input when inline */
   margin-bottom: 15px; /* gives padding to bottom of inline inputs */
}

this will help all of you to find your own correct details use

npm ls dist-tag

this will then show the correct info so you don't guess the version file location etc

enjoy :)

The use of _New is useful when working on pages that are Iframed. Since target="_blank" doesn't do the trick and opens the page on the same iframe... target new is the best solution for Iframe Pages. Just my five cents.

In Swift 3 something like this with @objc:

func startTimerForResendingCode() {
    let timerIntervalForResendingCode = TimeInterval(60)
    Timer.scheduledTimer(timeInterval: timerIntervalForResendingCode,
                         target: self,
                         selector: #selector(timerEndedUp),
                         userInfo: nil,
                         repeats: false)
}




@objc func timerEndedUp() {
    output?.timerHasFinishedAndCodeMayBeResended()
}

to force running only one instace of a program in .net (C#) use this code in program.cs file:

public static Process PriorProcess()
    // Returns a System.Diagnostics.Process pointing to
    // a pre-existing process with the same name as the
    // current one, if any; or null if the current process
    // is unique.
    {
        Process curr = Process.GetCurrentProcess();
        Process[] procs = Process.GetProcessesByName(curr.ProcessName);
        foreach (Process p in procs)
        {
            if ((p.Id != curr.Id) &&
                (p.MainModule.FileName == curr.MainModule.FileName))
                return p;
        }
        return null;
    }

and the folowing:

[STAThread]
    static void Main()
    {
        if (PriorProcess() != null)
        {

            MessageBox.Show("Another instance of the app is already running.");
            return;
        }
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        Application.Run(new Form());
    }

Two problems:

1 - You never told Git to start tracking any file

You write that you ran

git init
git commit -m "first commit"

and that, at that stage, you got

nothing added to commit but untracked files present (use "git add" to track).

Git is telling you that you never told it to start tracking any files in the first place, and it has nothing to take a snapshot of. Therefore, Git creates no commit. Before attempting to commit, you should tell Git (for instance):

Hey Git, you see that README.md file idly sitting in my working directory, there? Could you put it under version control for me? I'd like it to go in my first commit/snapshot/revision...

For that you need to stage the files of interest, using

git add README.md

before running

git commit -m "some descriptive message"

2 - You haven't set up the remote repository

You then ran

git remote add origin https://github.com/VijayNew/NewExample.git

After that, your local repository should be able to communicate with the remote repository that resides at the specified URL (https://github.com/VijayNew/NewExample.git)... provided that remote repo actually exists! However, it seems that you never created that remote repo on GitHub in the first place: at the time of writing this answer, if I try to visit the correponding URL, I get

Before attempting to push to that remote repository, you need to make sure that the latter actually exists. So go to GitHub and create the remote repo in question. Then and only then will you be able to successfully push with

git push -u origin master

Use Decimal.Truncate

It removes the fractional part from the decimal.

int i = (int)Decimal.Truncate(12.66m)

You can download the wheel corresponding to your configuration here ("Pillow-4.1.1-cp36-cp36m-win_amd64.whl" in your case) and install it with:

pip install some-package.whl

If you have problem to install the wheel read this answer

I think this would be a better way to do it in Swift:

func filterContentForSearchText(searchText:NSString, scope:NSString)
{
   searchResults = recipes.filter { name.rangeOfString(searchText) != nil  }
}

Without code this is difficult to help you but here's some practical advice for you:

I suspect that your "image wall" has some sort of container with an id or class to give it styles.

eg:

<body>

<div id="maincontainer">
  <div id="header"></div>

  <div id="content">
    <div id="imagewall">
      <img src"img.jpg">
<!-- code continues -->

Styling a size on all images for your image wall, while not affecting other images, like you logo, etc. is easy if your code is set up similar to the above.

#imagewall img {
  width: 100px;
  height: 100px; }

But if your images are not perfectly square they will be skewed using this method.

By default the function returns FALSE (boolean) if the segment does not exist. There is an optional second parameter that permits you to set your own default value if the segment is missing. For example, this would tell the function to return the number zero in the event of failure: $product_id = $this->uri->segment(3, 0);

It helps avoid having to write code like this:

[if ($this->uri->segment(3) === FALSE)
{
    $product_id = 0;
}
else
{
    $product_id = $this->uri->segment(3);
}]

This one worked for me

$('#Form').submit(function(){
var btn= $(this).find("input[type=submit]:focus").val();
alert('you have clicked '+ btn);

}

Your code looks great, the only thing i see is that you did not include the collapsed class in your button selector. http://www.bootply.com/cpHugxg2f8 Note: Requires JavaScript plugin If JavaScript is disabled and the viewport is narrow enough that the navbar collapses, it will be impossible to expand the navbar and view the content within the .navbar-collapse.

The responsive navbar requires the collapse plugin to be included in your version of Bootstrap.

<div class="navbar-wrapper">
      <div class="container">

        <nav class="navbar navbar-inverse navbar-static-top">
          <div class="container">
            <div class="navbar-header">
              <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="navbar">
                <span class="sr-only">Toggle navigation</span>
                <span class="icon-bar"></span>
                <span class="icon-bar"></span>
                <span class="icon-bar"></span>
              </button>
              <a class="navbar-brand" href="#">Project name</a>
            </div>
            <div id="navbar" class="navbar-collapse collapse">
              <ul class="nav navbar-nav">
                    <li><a href="">Page 1</a>
                    </li>
                    <li><a href="">Page 2</a>
                    </li>
                    <li><a href="">Page 3</a>
                    </li>

              </ul>
            </div>
          </div>
        </nav>

      </div>
    </div>

Ctrl+Shift+Space shows the Edit.ParameterInfo for the selected method, and by selected method I mean the caret must be within the method parentheses.

Here is the Visual Studio 2010 Keybinding Poster.

And for those still using 2008.

You can use your original script to set the variables, but you need to call it the following way (with stand-alone dot):

. ./minientrega.sh

Also there might be an issue with cat | while read approach. I would recommend to use the approach while read line; do .... done < $FILE.

Here is a working example:

> cat test.conf
VARIABLE_TMP1=some_value

> cat run_test.sh
#/bin/bash
while read line; do export "$line";
done < test.conf
echo "done"

> . ./run_test.sh
done

> echo $VARIABLE_TMP1
some_value

I think that you should use mysqli_connect instead of mysql_connect

This is an option:

dbContext.Entry(entity).State = EntityState.Detached;

There are a lot of really weirdly complicated answers to this question. Am I oversimplifying this, because this seems sufficient for most things to me.

from threading import Thread

class PropagatingThread(Thread):
    def run(self):
        self.exc = None
        try:
            if hasattr(self, '_Thread__target'):
                # Thread uses name mangling prior to Python 3.
                self.ret = self._Thread__target(*self._Thread__args, **self._Thread__kwargs)
            else:
                self.ret = self._target(*self._args, **self._kwargs)
        except BaseException as e:
            self.exc = e

    def join(self):
        super(PropagatingThread, self).join()
        if self.exc:
            raise self.exc
        return self.ret

If you're certain you'll only ever be running on one or the other version of Python, you could reduce the run() method down to just the mangled version (if you'll only be running on versions of Python before 3), or just the clean version (if you'll only be running on versions of Python starting with 3).

Example usage:

def f(*args, **kwargs):
    print(args)
    print(kwargs)
    raise Exception('I suck at this')

t = PropagatingThread(target=f, args=(5,), kwargs={'hello':'world'})
t.start()
t.join()

And you'll see the exception raised on the other thread when you join.

If you are using six or on Python 3 only, you can improve the stack trace information you get when the exception is re-raised. Instead of only the stack at the point of the join, you can wrap the inner exception in a new outer exception, and get both stack traces with

six.raise_from(RuntimeError('Exception in thread'),self.exc)

or

raise RuntimeError('Exception in thread') from self.exc

bash:

fspec="/exp/home1/abc.txt"
fname="${fspec##*/}"

Here are some examples from this blog mentioned earlier:

<configuration>    
   <Database>    
      <add key="ConnectionString" value="data source=.;initial catalog=NorthWind;integrated security=SSPI"/>    
   </Database>    
</configuration>  

get values:

 NameValueCollection db = (NameValueCollection)ConfigurationSettings.GetConfig("Database");         
    labelConnection2.Text = db["ConnectionString"];

-

Another example:

<Locations 
   ImportDirectory="C:\Import\Inbox"
   ProcessedDirectory ="C:\Import\Processed"
   RejectedDirectory ="C:\Import\Rejected"
/>

get value:

Hashtable loc = (Hashtable)ConfigurationSettings.GetConfig("Locations"); 

labelImport2.Text = loc["ImportDirectory"].ToString();
labelProcessed2.Text = loc["ProcessedDirectory"].ToString();

You simply have to use the filter filter (see the documentation) :

<div id="totalPos">{{(tweets | filter:{polarity:'Positive'}).length}}</div>
<div id="totalNeut">{{(tweets | filter:{polarity:'Neutral'}).length}}</div>
<div id="totalNeg">{{(tweets | filter:{polarity:'Negative'}).length}}</div>

Fiddle

As of iOS 5, Apple now allows you to make custom containers for the purpose of adding a UIViewController to another UIViewController particularly via methods such as addChildViewController so it is indeed possible to nest UIViewControllers

EDIT: Including in-place summary so as to avoid link breakage

I quote:

iOS provides many standard containers to help you organize your apps. However, sometimes you need to create a custom workflow that doesn’t match that provided by any of the system containers. Perhaps in your vision, your app needs a specific organization of child view controllers with specialized navigation gestures or animation transitions between them. To do that, you implement a custom container - Tell me more...

...and:

When you design a container, you create explicit parent-child relationships between your container, the parent, and other view controllers, its children - Tell me more

Sample (courtesy of Apple docs) Adding another view controller’s view to the container’s view hierarchy

- (void) displayContentController: (UIViewController*) content
{
   [self addChildViewController:content];                 
   content.view.frame = [self frameForContentController]; 
   [self.view addSubview:self.currentClientView];
   [content didMoveToParentViewController:self];          
}

You will not write code into a static block that needs to be invoked anywhere in your program. If the purpose of the code is to be invoked then you must place it in a method.

You can write static initializer blocks to initialize static variables when the class is loaded but this code can be more complex..

A static initializer block looks like a method with no name, no arguments, and no return type. Since you never call it it doesn't need a name. The only time its called is when the virtual machine loads the class.

JavaScript syntax 101. Here is a function declaration:

function foo() {}

Note that there's no semicolon: this is just a function declaration. You would need an invocation, foo(), to actually run the function.

Now, when we add the seemingly innocuous exclamation mark: !function foo() {} it turns it into an expression. It is now a function expression.

The ! alone doesn't invoke the function, of course, but we can now put () at the end: !function foo() {}() which has higher precedence than ! and instantly calls the function.

So what the author is doing is saving a byte per function expression; a more readable way of writing it would be this:

(function(){})();

Lastly, ! makes the expression return true. This is because by default all immediately invoked function expressions (IIFE) return undefined, which leaves us with !undefined which is true. Not particularly useful.

All the download process is too long, just navigate to your project preview and select project view, right click on app folder, then click on new, then create a new image asset. Kindly choose the file path and click next and finish.

important: Reinstall your app.

Founder a simple solution here:

https://stackoverflow.com/a/47132808/9656339

pd.concat([df1, df2]).loc[df1.index.symmetric_difference(df2.index)]

You can use the flip commands numpy.flipud() or numpy.fliplr() to get the indexes in descending order after sorting using the argsort command. Thats what I usually do.

I can confirm this works. I exported the reg file after I had made the adjustments and then put it in a logon script like this:

REM ------ IE Auto Detect Settings FIX ------------------
REG IMPORT \\mydomain.local\netlogon\IE-Autofix.reg 2>NUL

You are almost always better off using an options hash.

def ldap_get(base_dn, filter, options = {})
  options[:scope] ||= LDAP::LDAP_SCOPE_SUBTREE
  ...
end

ldap_get(base_dn, filter, :attrs => X)

For example you want to find a mean of each column in matrix. Let's create the following matrix

mat2 = np.array([1,5,6,7,3,0,3,5,9,10,8,0], dtype=np.float64).reshape(3, 4)

The function for mean is

def my_mean(x):
    return sum(x)/len(x)

To do what is needed and store result in colon vector 'results'

results = np.zeros(4)
for i in range(0, 4):
    mat2[:, i] = my_mean(mat2[:, i])

results = mat2[1,:]      

The results are: array([4.33333333, 5. , 5.66666667, 4. ])

This is a slightly modified solution. The Process will be killed when it was idle for at least 1 second. Maybe you should add a timeof of X seconds and call the function from a separate thread.

private void SendToPrinter()
{
  ProcessStartInfo info = new ProcessStartInfo();
  info.Verb = "print";
  info.FileName = @"c:\output.pdf";
  info.CreateNoWindow = true;
  info.WindowStyle = ProcessWindowStyle.Hidden;

  Process p = new Process();
  p.StartInfo = info;
  p.Start();

  long ticks = -1;
  while (ticks != p.TotalProcessorTime.Ticks)
  {
    ticks = p.TotalProcessorTime.Ticks;
    Thread.Sleep(1000);
  }

  if (false == p.CloseMainWindow())
    p.Kill();
}

You probably want to make a range query, for example, all items created after a given date:

db.gpsdatas.find({"createdAt" : { $gte : new ISODate("2012-01-12T20:15:31Z") }});

I'm using $gte (greater than or equals), because this is often used for date-only queries, where the time component is 00:00:00.

If you really want to find a date that equals another date, the syntax would be

db.gpsdatas.find({"createdAt" : new ISODate("2012-01-12T20:15:31Z") });

I had this happen repeatedly after adding images to a project in Eclipse and making them part of the build path. The solution was to right-click on the class containing the main method, and then choose Run As -> Java Application. It seems that when you add a file to the build path, Eclipse automatically assumes that file is where the main method is. By going through the Run As menu instead of just clicking the green Run As button, it allows you to specify the correct entry-point.

I'm going to make a couple of assumptions in my answer. I'm assuming your data starts in A1 and there are no empty cells in the first column of each row that has data.

This code will:

1. Find the last row in column A that has data
2. Loop through each row
3. Find the last column in current row with data
4. Loop through each cell in current row up to last column found.

This is not a fast method but will iterate through each one individually as you suggested is your intention.

Sub iterateThroughAll()
    ScreenUpdating = False
    Dim wks As Worksheet
    Set wks = ActiveSheet

    Dim rowRange As Range
    Dim colRange As Range

    Dim LastCol As Long
    Dim LastRow As Long
    LastRow = wks.Cells(wks.Rows.Count, "A").End(xlUp).Row

    Set rowRange = wks.Range("A1:A" & LastRow)

    'Loop through each row
    For Each rrow In rowRange
        'Find Last column in current row
        LastCol = wks.Cells(rrow, wks.Columns.Count).End(xlToLeft).Column
        Set colRange = wks.Range(wks.Cells(rrow, 1), wks.Cells(rrow, LastCol))

        'Loop through all cells in row up to last col
        For Each cell In colRange
            'Do something to each cell
            Debug.Print (cell.Value)
        Next cell
    Next rrow
    ScreenUpdating = True
End Sub

You can use:

width: -webkit-fit-content;
height: -webkit-fit-content;
width: -moz-fit-content;
height: -moz-fit-content;

a couple years down the road, I'd vote for three.js because

ie 11 supports webgl (to what extent I can't assure you since i'm usually in chrome)

and, as far as importing external models into three.js, here's a link to mrdoob's updated loaders (so many!)

UPDATE nov 2019: the THREE.js loaders are now far more and it makes little sense to post them all: just go to this link

http://threejs.org/examples and review the loaders - at least 20 of them

Call

element.iCheck('update');

To get the updated markup on the element

 SELECT * FROM users WHERE Id Between 15 and 25

it will print from 15 to 25 as like limit in MYSQl

@CMS's answer is just fine, but I want to note that you can use this package: https://github.com/sindresorhus/slugify, which does it for you and covers many edge cases (i.e., German umlauts, Vietnamese, Arabic, Russian, Romanian, Turkish, etc.).

Pretty late response but you can do the following in Kotlin:

activity?.applicationContext?.let { SymptomsAdapters(it, param2, param3, ...) }

(?.) is for safe null operation to prevent from the null pointer exception.

You do not want to create a new context as that can lead to memory leaks when interchanging between fragments or when the device changes rotation.

And as someone mentioned above, in Java you can obtain context in a fragment by doing the following:

getActivity().getApplicationContext()

Taking some answers one step further - if you do the following you can check if any element within the radio group has been checked:

if ($('input[name="yourRadioNames"]:checked').val()){ (checked) or if (!$('input[name="yourRadioNames"]:checked').val()){ (not checked)

You can also use short trick to use image and color both like this :-

body {
     background:#000 url('images/checked.png');
 }

In VB : This should work

ConfigurationManager.ConnectionStrings("SQLServer").ConnectionString

In C# it would be (as per comment of Ala)

ConfigurationManager.ConnectionStrings["SQLServer"].ConnectionString

in the folder where the build.xml resides run command only -

ant

and not the command - `

ant build.xml

`

. if you are using the ant file as build xml then the below steps helps you Steps : open cmd Prompt >> switch to the project location >>type ant and click enter key

If you add an alert right after the buster code, then the alert will stall the javascript thread, and it will let the page load. This is what StackOverflow does, and it busts out of my iframes, even when I use the frame busting buster. It also worked with my simple test page. This has only been tested in Firefox 3.5 and IE7 on windows.

Code:

<script type="text/javascript">
if (top != self){
  top.location.replace(self.location.href);
  alert("for security reasons bla bla bla");
}
</script>

I get into ElementNotVisibleException exception using selenium for functional tests on a django site with bootstrap glyphicons as links in templates as:

<a href="{% url 'item-add' %}"><span class="glyphicon glyphicon-plus text-danger"></span></a>

During my functional tests, the bootstrap style is not loaded, then trying to click on such links will raise ElementNotVisibleException. I manage to make them clickable just adding a space in the tag, like that:

<a href="{% url 'item-add' %}"><span class="glyphicon glyphicon-plus text-danger">&nbsp;</span></a>

0(logn)-Binary search, peak element in an array(there can be more than one peak) 0(1)-in python calculating the length of a list or a string. The len() function takes 0(1) time. Accessing an element in an array takes 0(1) time. Push operation in a stack takes 0(1) time. 0(nlogn)-Merge sort. sorting in python takes nlogn time. so when you use listname.sort() it takes nlogn time.

Note-Searching in a hash table sometimes takes more than constant time because of collisions.

this is an interesting question so let check it if you have a image for use as a website-icon then

Add this to your script

   <link rel="icon" type="image/gif" href="animated_favicon1.gif" />

otherwise if you have a icon for your website icon then you chose

 <link rel="shortcut icon" href="favicon.ico" />

I always use http://www.iconspedia.com/ for more icons

if my answer solved your problem then give me vote ok

This an alternate code to other answers:

x[, sapply(x, class) == "numeric"]

with a data.table

x[, lapply(x, is.numeric) == TRUE, with = FALSE]

cache:true only works with GET and HEAD request.

You could roll your own solution as you said with something along these lines :

var localCache = {
    data: {},
    remove: function (url) {
        delete localCache.data[url];
    },
    exist: function (url) {
        return localCache.data.hasOwnProperty(url) && localCache.data[url] !== null;
    },
    get: function (url) {
        console.log('Getting in cache for url' + url);
        return localCache.data[url];
    },
    set: function (url, cachedData, callback) {
        localCache.remove(url);
        localCache.data[url] = cachedData;
        if ($.isFunction(callback)) callback(cachedData);
    }
};

$(function () {
    var url = '/echo/jsonp/';
    $('#ajaxButton').click(function (e) {
        $.ajax({
            url: url,
            data: {
                test: 'value'
            },
            cache: true,
            beforeSend: function () {
                if (localCache.exist(url)) {
                    doSomething(localCache.get(url));
                    return false;
                }
                return true;
            },
            complete: function (jqXHR, textStatus) {
                localCache.set(url, jqXHR, doSomething);
            }
        });
    });
});

function doSomething(data) {
    console.log(data);
}

Working fiddle here

EDIT: as this post becomes popular, here is an even better answer for those who want to manage timeout cache and you also don't have to bother with all the mess in the $.ajax() as I use $.ajaxPrefilter(). Now just setting {cache: true} is enough to handle the cache correctly :

var localCache = {
    /**
     * timeout for cache in millis
     * @type {number}
     */
    timeout: 30000,
    /** 
     * @type {{_: number, data: {}}}
     **/
    data: {},
    remove: function (url) {
        delete localCache.data[url];
    },
    exist: function (url) {
        return !!localCache.data[url] && ((new Date().getTime() - localCache.data[url]._) < localCache.timeout);
    },
    get: function (url) {
        console.log('Getting in cache for url' + url);
        return localCache.data[url].data;
    },
    set: function (url, cachedData, callback) {
        localCache.remove(url);
        localCache.data[url] = {
            _: new Date().getTime(),
            data: cachedData
        };
        if ($.isFunction(callback)) callback(cachedData);
    }
};

$.ajaxPrefilter(function (options, originalOptions, jqXHR) {
    if (options.cache) {
        var complete = originalOptions.complete || $.noop,
            url = originalOptions.url;
        //remove jQuery cache as we have our own localCache
        options.cache = false;
        options.beforeSend = function () {
            if (localCache.exist(url)) {
                complete(localCache.get(url));
                return false;
            }
            return true;
        };
        options.complete = function (data, textStatus) {
            localCache.set(url, data, complete);
        };
    }
});

$(function () {
    var url = '/echo/jsonp/';
    $('#ajaxButton').click(function (e) {
        $.ajax({
            url: url,
            data: {
                test: 'value'
            },
            cache: true,
            complete: doSomething
        });
    });
});

function doSomething(data) {
    console.log(data);
}

And the fiddle here CAREFUL, not working with $.Deferred

Here is a working but flawed implementation working with deferred:

var localCache = {
    /**
     * timeout for cache in millis
     * @type {number}
     */
    timeout: 30000,
    /** 
     * @type {{_: number, data: {}}}
     **/
    data: {},
    remove: function (url) {
        delete localCache.data[url];
    },
    exist: function (url) {
        return !!localCache.data[url] && ((new Date().getTime() - localCache.data[url]._) < localCache.timeout);
    },
    get: function (url) {
        console.log('Getting in cache for url' + url);
        return localCache.data[url].data;
    },
    set: function (url, cachedData, callback) {
        localCache.remove(url);
        localCache.data[url] = {
            _: new Date().getTime(),
            data: cachedData
        };
        if ($.isFunction(callback)) callback(cachedData);
    }
};

$.ajaxPrefilter(function (options, originalOptions, jqXHR) {
    if (options.cache) {
        //Here is our identifier for the cache. Maybe have a better, safer ID (it depends on the object string representation here) ?
        // on $.ajax call we could also set an ID in originalOptions
        var id = originalOptions.url+ JSON.stringify(originalOptions.data);
        options.cache = false;
        options.beforeSend = function () {
            if (!localCache.exist(id)) {
                jqXHR.promise().done(function (data, textStatus) {
                    localCache.set(id, data);
                });
            }
            return true;
        };

    }
});

$.ajaxTransport("+*", function (options, originalOptions, jqXHR, headers, completeCallback) {

    //same here, careful because options.url has already been through jQuery processing
    var id = originalOptions.url+ JSON.stringify(originalOptions.data);

    options.cache = false;

    if (localCache.exist(id)) {
        return {
            send: function (headers, completeCallback) {
                completeCallback(200, "OK", localCache.get(id));
            },
            abort: function () {
                /* abort code, nothing needed here I guess... */
            }
        };
    }
});

$(function () {
    var url = '/echo/jsonp/';
    $('#ajaxButton').click(function (e) {
        $.ajax({
            url: url,
            data: {
                test: 'value'
            },
            cache: true
        }).done(function (data, status, jq) {
            console.debug({
                data: data,
                status: status,
                jqXHR: jq
            });
        });
    });
});

Fiddle HERE Some issues, our cache ID is dependent of the json2 lib JSON object representation.

Use Console view (F12) or FireBug to view some logs generated by the cache.

MartinVonMartinsgrün and 4Levels methods confirmed work great on Mac OS X Mountain Lion.

The file I needed to update was ~/.profile.

However, I couldn't leave this question without recommending my favorite application, iTerm 2.

iTerm 2 lets you load global color schemes from a file. Really easy to experiment and try a bunch of color schemes.

Here's a screenshot of the iTerm 2 window and the color preferences.

Once I added the following to my ~/.profile file iTerm 2 was able to override the colors.

export CLICOLOR=1
export LSCOLORS=GxFxCxDxBxegedabagaced
export PS1='\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '

Here is a great repository with some nice presets:

iTerm2 Color Schemes on Github by mbadolato

Bonus: Choose "Show/hide iTerm2 with a system-wide hotkey" and bind the key with BetterTouchTool for an instant hide/show the terminal with a mouse gesture.

Depending on the libc release it could be needed to set both SO_REUSEADDR and SO_REUSEPORT socket options as explained in socket(7) documentation :

   SO_REUSEPORT (since Linux 3.9)
          Permits multiple AF_INET or AF_INET6 sockets to be bound to an
          identical socket address.  This option must be set on each
          socket (including the first socket) prior to calling bind(2)
          on the socket.  To prevent port hijacking, all of the
          processes binding to the same address must have the same
          effective UID.  This option can be employed with both TCP and
          UDP sockets.

As this socket option appears with kernel 3.9 and raspberry use 3.12.x, it will be needed to set SO_REUSEPORT.

You can set theses two options before calling bind like this :

    int reuse = 1;
    if (setsockopt(sockfd, SOL_SOCKET, SO_REUSEADDR, (const char*)&reuse, sizeof(reuse)) < 0)
        perror("setsockopt(SO_REUSEADDR) failed");

#ifdef SO_REUSEPORT
    if (setsockopt(sockfd, SOL_SOCKET, SO_REUSEPORT, (const char*)&reuse, sizeof(reuse)) < 0) 
        perror("setsockopt(SO_REUSEPORT) failed");
#endif

I found that I could access the checkbox directly using Worksheets("SheetName").CB_Checkboxname.value directly without relating to additional objects.

@thebjorn has given a good answer. But if you want more options, you can try OpenCV, SimpleCV.

using SimpleCV (not supported in python3.x):

from SimpleCV import Image, Camera

cam = Camera()
img = cam.getImage()
img.save("filename.jpg")

using OpenCV:

from cv2 import *
# initialize the camera
cam = VideoCapture(0)   # 0 -> index of camera
s, img = cam.read()
if s:    # frame captured without any errors
    namedWindow("cam-test",CV_WINDOW_AUTOSIZE)
    imshow("cam-test",img)
    waitKey(0)
    destroyWindow("cam-test")
    imwrite("filename.jpg",img) #save image

using pygame:

import pygame
import pygame.camera

pygame.camera.init()
pygame.camera.list_cameras() #Camera detected or not
cam = pygame.camera.Camera("/dev/video0",(640,480))
cam.start()
img = cam.get_image()
pygame.image.save(img,"filename.jpg")

Install OpenCV:

install python-opencv bindings, numpy

Install SimpleCV:

install python-opencv, pygame, numpy, scipy, simplecv

get latest version of SimpleCV

Install pygame:

install pygame

I seriously do think that it is code smell if you need to mock static methods, too.

• Static methods to access common functionality? -> Use a singleton instance and inject that
• Third party code? -> Wrap it into your own interface/delegate (and if necessary make it a singleton, too)

The only time this seems overkill to me, is libs like Guava, but you shouldn't need to mock this kind anyway cause it's part of the logic... (stuff like Iterables.transform(..))
That way your own code stays clean, you can mock out all your dependencies in a clean way, and you have an anti corruption layer against external dependencies. I've seen PowerMock in practice and all the classes we needed it for were poorly designed. Also the integration of PowerMock at times caused serious problems
(e.g. https://code.google.com/p/powermock/issues/detail?id=355)

PS: Same holds for private methods, too. I don't think tests should know about the details of private methods. If a class is so complex that it tempts to mock out private methods, it's probably a sign to split up that class...

You can use TreeMap which internally implements the SortedMap below is the example

Sorting by ascending ordering :

  Map<Float, String> ascsortedMAP = new TreeMap<Float, String>();

  ascsortedMAP.put(8f, "name8");
  ascsortedMAP.put(5f, "name5");
  ascsortedMAP.put(15f, "name15");
  ascsortedMAP.put(35f, "name35");
  ascsortedMAP.put(44f, "name44");
  ascsortedMAP.put(7f, "name7");
  ascsortedMAP.put(6f, "name6");

  for (Entry<Float, String> mapData : ascsortedMAP.entrySet()) {
    System.out.println("Key : " + mapData.getKey() + "Value : " + mapData.getValue());
  }

Sorting by descending ordering :

If you always want this create the map to use descending order in general, if you only need it once create a TreeMap with descending order and put all the data from the original map in.

  // Create the map and provide the comparator as a argument
  Map<Float, String> dscsortedMAP = new TreeMap<Float, String>(new Comparator<Float>() {
    @Override
    public int compare(Float o1, Float o2) {
      return o2.compareTo(o1);
    }
  });
  dscsortedMAP.putAll(ascsortedMAP);

for further information about SortedMAP read http://examples.javacodegeeks.com/core-java/util/treemap/java-sorted-map-example/

I've also had this issue.

I've found out that it is because Eclipse couldn't find all include headers.

Easy fix:

This simple and quick solution might fix your problem (for example, when the Eclipse project was moved to a different location on disk, then imported again in Eclipse), if not, jump to the next section (Detailed fix).

1. Go to project > properties > C/C++ Build > Tool Chain Editor
2. Change the Current toolchain to any other value, click Apply
3. Set the Current toolchain to the original value, click Apply
4. Compile your project

Detailed fix:

Before proceeding check if your toolchain is properly installed.

1. Switch to a new workspace.
2. Remove .cproject file and the ".settings" folder
3. Import your project as Makefile project (or just create a new if you prefer CDT Build system)
4. Go to project-> properties->C/C++ Build->Toolchain editor. Choose your toolchain.
5. Press project->Index->Rebuild
6. If the problem isn't resolved, change system language to English and try the above steps again.

Outdated answer:

This answer has been outdated. Proceed if nothing of the above helps

If the previous steps don't help we'll need to setup include directories manually (not recommended though)

1. Search all unresolved headers using "Right click on Project > Index > Search for unresolved includes".
2. Search their locations using "find /usr/include/ -name vector -print"
3. Put include folder paths to "Right click on Project > Properties > C++ General/Path and Symbols/C++"
4. Run "Right click on Project > Index > Rebuild"
5. Start from step 1 if there are any unresolved symbols left.

I know a lot's of time has passed since this publish, but I've fallen in a similar situation and create a simples class to simplify my life.

public struct StringMaskFormatter {

    public var pattern              : String    = ""
    public var replecementChar      : Character = "*"
    public var allowNumbers         : Bool      = true
    public var allowText            : Bool      = false


    public init(pattern:String, replecementChar:Character="*", allowNumbers:Bool=true, allowText:Bool=true)
    {
        self.pattern            = pattern
        self.replecementChar    = replecementChar
        self.allowNumbers       = allowNumbers
        self.allowText          = allowText
    }


    private func prepareString(string:String) -> String {

        var charSet : NSCharacterSet!

        if allowText && allowNumbers {
            charSet = NSCharacterSet.alphanumericCharacterSet().invertedSet
        }
        else if allowText {
            charSet = NSCharacterSet.letterCharacterSet().invertedSet
        }
        else if allowNumbers {
            charSet = NSCharacterSet.decimalDigitCharacterSet().invertedSet
        }

        let result = string.componentsSeparatedByCharactersInSet(charSet)
        return result.joinWithSeparator("")
    }

    public func createFormattedStringFrom(text:String) -> String
    {
        var resultString = ""
        if text.characters.count > 0 && pattern.characters.count > 0
        {

            var finalText   = ""
            var stop        = false
            let tempString  = prepareString(text)

            var formatIndex = pattern.startIndex
            var tempIndex   = tempString.startIndex

            while !stop
            {
                let formattingPatternRange = formatIndex ..< formatIndex.advancedBy(1)

                if pattern.substringWithRange(formattingPatternRange) != String(replecementChar) {
                    finalText = finalText.stringByAppendingString(pattern.substringWithRange(formattingPatternRange))
                }
                else if tempString.characters.count > 0 {
                    let pureStringRange = tempIndex ..< tempIndex.advancedBy(1)
                    finalText = finalText.stringByAppendingString(tempString.substringWithRange(pureStringRange))
                    tempIndex = tempIndex.advancedBy(1)
                }

                formatIndex = formatIndex.advancedBy(1)

                if formatIndex >= pattern.endIndex || tempIndex >= tempString.endIndex {
                    stop = true
                }

                resultString = finalText

            }
        }

        return resultString
    }

This solution was base on this article: http://vojtastavik.com/2015/03/29/real-time-formatting-in-uitextfield-swift-basics/

Yes, Daniel is correct, but to expand upon his answer, your primary app component would need to have a navbar component within it. That way, when you render the primary app (any page under the '/' path), it would also display the navbar. I am guessing that you wouldn't want your login page to display the navbar, so that shouldn't be a nested component, and should instead be by itself. So your routes would end up looking something like this:

<Router>
  <Route path="/" component={App}>
    <Route path="page1" component={Page1} />
    <Route path="page2" component={Page2} />
  </Route>
  <Route path="/login" component={Login} />
</Router>

And the other components would look something like this:

var NavBar = React.createClass({
  render() {
    return (
      <div>
        <ul>
          <a onClick={() => history.push('page1') }>Page 1</a>
          <a onClick={() => history.push('page2') }>Page 2</a>
        </ul>
      </div>
    )
  }
});

var App = React.createClass({
  render() {
    return (
      <div>
        <NavBar />
        <div>Other Content</div>
        {this.props.children}
      </div>
    )
  }
});

<div style="width:1px;background-color:red;height:30px;float:right;"></div>

Easily can be done using a div like this

You will need to configure your apache2.conf to make phpMyAdmin works.

sudo nano /etc/apache2/apache2.conf

Then add the following line to the end of the file.

Include /etc/phpmyadmin/apache.conf

Then restart apache

sudo service apache2 restart

You can use .add() and .subtract() method to get yesterday and tomorrow date. Then use format method to get only date .format("D/M/Y"), D stand for Day, M for Month, Y for Year. Check in Moment Docs

 let currentMilli = Date.now()
 let today = Moment(currentMilli).format("D/M/Y");
 let tomorrow = Moment(currentMilli).add(1, 'days').format("D/M/Y");
 let yesterday = Moment(currentMilli).subtract(1, 'days').format("D/M/Y");

Result will be:

Current Milli - 1576693800000
today - 19/12/2019
tomorrow - 18/12/2019
yesterday - 18/12/2019

This tool: jscompressor.com is pretty good.

1st: goto the drive where your eclipse reside and goto sdk and platform tool in my case C:\adt-bundle-windows-x86_64-20140702\sdk\platform-tools

2nd:copy that address for ease of access

3:open command prompt win+r and type cmd hit enter

4:paste the address in cmd and hit enter thats all

fixed my agent string evaluation by scrubbing the string for LOWERCASE "iphone os 5_0" as opposed to "iPhone OS 5_0." now i am properly assigning iOS 5 specific classes to my html, when the uppercase scrub failed.

IMPORTANT: <button> should never be a descendent of <a>.

Try <a href="http://stackoverflow.com"><button>Link Text</button></a> in any html validator like https://validator.w3.org and you'll get an error. There's really no point in using a button if you're not using the button. Just style the <a> with css to look like a button. If you're using a framework like Bootstrap, you could apply the button style(s) btn, btn-primary etc.

If i understand your question you want to have the overlay just over the image and not cover everything?

I'd set the parent DIV (i renamed in content in the jsfiddle) position to relative, as the overlay should be positioned relative to this div not the window.

.content
{
  position: relative;
}

I did some pocking around and updated your fiddle to just have the overlay sized to the img which (I think) is what you want, let me know anyway :) http://jsfiddle.net/b9Vyw/

I like Alex FTPS Client which is written by a Microsoft MVP name Alex Pilotti. It's a C# library you can use in Console apps, Windows Forms, PowerShell, ASP.NET (in any .NET language). If you have a multithreaded app you will have to configure the library to run syncronously, but overall a good client that will most likely get you what you need.

I encountered the same issue. You have to use ActiveX or Flash (or Java). The good thing is that it doesn't have to be invasive. I have a simple ActiveX method that will return the size of the to-be-uploaded file.

If you go with Flash, you can even do some fancy js/css to cusomize the uploading experience--only using Flash (as a 1x1 "movie") to access it's file uploading features.

Based on the above mentioned answers, I managed to compare my custom Class Objects like this:

ArrayList<Item> itemList = new ArrayList<>();
...
Collections.sort(itemList, new Comparator<Item>() {
            @Override
            public int compare(Item item, Item t1) {
                String s1 = item.getTitle();
                String s2 = t1.getTitle();
                return s1.compareToIgnoreCase(s2);
            }

        });

Something like this:

$(myObj).attr({"data-test-1": num1, "data-test-2": num2});

The following "Cake way" is useful because you can grab the full current URL and modify parts of it without manually having to parse out the $_SERVER[ 'REQUEST_URI' ] string and then manually concatenating it back into a valid url for output.

Full current url:
Router::reverse($this->request, true)

Easily modifying specific parts of current url:
1) make a copy of Cake's request object: $request_copy = $this->request

2) Then modify $request_copy->params and/or $request_copy->query arrays

3) Finally: $new_url = Router::reverse($request_copy, true).

This should work:

window.onload = function() {
  document.getElementById('about').className = 'expand';
};

Or if you're using jQuery:

$(function() {
  $('#about').addClass('expand');
});

Jquery later allowed you to to find the parents with the .parents() method.

Hence I recommend using:

var $div = $('#divid').parents('div[class^="div-a"]');

This gives all parent nodes matching the selector. To get the first parent matching the selector use:

var $div = $('#divid').parents('div[class^="div-a"]').eq(0);

For other such DOM traversal queries, check out the documentation on traversing the DOM.

According to this site, this is supported in the playbackRate and defaultPlaybackRate attributes, accessible via the DOM. Example:

/* play video twice as fast */
document.querySelector('video').defaultPlaybackRate = 2.0;
document.querySelector('video').play();

/* now play three times as fast just for the heck of it */
document.querySelector('video').playbackRate = 3.0;

The above works on Chrome 43+, Firefox 20+, IE 9+, Edge 12+.

If anybody else had a problem with best answer's solution (including disabling foreign keys), here is another solution from me:

-- CLEAN DB
USE [DB_NAME]
    EXEC sp_MSForEachTable 'ALTER TABLE ? NOCHECK CONSTRAINT ALL'
    EXEC sp_MSForEachTable 'DELETE FROM ?'

    DECLARE @Sql NVARCHAR(500) DECLARE @Cursor CURSOR
    SET @Cursor = CURSOR FAST_FORWARD FOR

    SELECT DISTINCT sql = 'ALTER TABLE [' + tc2.TABLE_NAME + '] DROP [' + rc1.CONSTRAINT_NAME + ']'
    FROM INFORMATION_SCHEMA.REFERENTIAL_CONSTRAINTS rc1
    LEFT JOIN INFORMATION_SCHEMA.TABLE_CONSTRAINTS tc2 ON tc2.CONSTRAINT_NAME =rc1.CONSTRAINT_NAME
    OPEN @Cursor FETCH NEXT FROM @Cursor INTO @Sql
    WHILE (@@FETCH_STATUS = 0)
      BEGIN
        Exec SP_EXECUTESQL @Sql
        FETCH NEXT 
        FROM @Cursor INTO @Sql
      END
    CLOSE @Cursor DEALLOCATE @Cursor
    GO

    EXEC sp_MSForEachTable 'DROP TABLE ?'
    GO

    EXEC sp_MSForEachTable 'ALTER TABLE ? WITH CHECK CHECK CONSTRAINT ALL'

you can set PYTHONPATH, by os.environ['PATHPYTHON']=/some/path, then you need to call os.system('python') to restart the python shell to make the newly added path effective.

By omitting all parts of the head, the loop can also become infinite:

for (;;) {}

You can get the all record of the date '2016-07-14' by using it

 whereDate('date','=','2016-07-14')

Or use the another code for dynamic date

whereDate('date',$date)

<input type="submit" value="Create" name="button"/>_x000D_
<input type="submit" value="Reset" name="button" />

write the following code in Controler.

[HttpPost]
        public ActionResult Login(string button)
        {
            switch (button)
            {
                case "Create":
                    return RedirectToAction("Deshboard", "Home");
                    break;
                case "Reset":
                    return RedirectToAction("Login", "Home");
                    break;
            }

            return View();
        }

If you want to know this, it exists an open source library called aFileDialog that it is an small and easy to use which provides a file picker.

The difference with another file chooser's libraries for Android is that aFileDialog gives you the option to open the file chooser as a Dialog and as an Activity.

It also lets you to select folders, create files, filter files using regular expressions and show confirmation dialogs.

In Python, lambda is a keyword used to define anonymous functions(functions with no name) and that's why they are known as lambda functions.

Basically it is used for defining anonymous functions that can/can't take argument(s) and returns value of data/expression. Let's see an example.

>>> # Defining a lambda function that takes 2 parameters(as integer) and returns their sum
... 
>>> lambda num1, num2: num1 + num2 
<function <lambda> at 0x1004b5de8>
>>> 
>>> # Let's store the returned value in variable & call it(1st way to call)
... 
>>> addition = lambda num1, num2: num1 + num2
>>> addition(62, 5)
67
>>> addition(1700, 29)
1729
>>> 
>>> # Let's call it in other way(2nd way to call, one line call )
... 
>>> (lambda num1, num2: num1 + num2)(120, 1)
121
>>> (lambda num1, num2: num1 + num2)(-68, 2)
-66
>>> (lambda num1, num2: num1 + num2)(-68, 2**3)
-60
>>> 

Now let me give an answer of your 2nd question. The 1st answer is also great. This is my own way to explain with another example.

Suppose we have a list of items(integers and strings with numeric contents) as follows,

nums = ["2", 1, 3, 4, "5", "8", "-1", "-10"]

and I want to sort it using sorted() function, lets see what happens.

>>> nums = ["2", 1, 3, 4, "5", "8", "-1", "-10"]
>>> sorted(nums)
[1, 3, 4, '-1', '-10', '2', '5', '8']
>>>

It didn't give me what I expected as I wanted like below,

['-10', '-1', 1, '2', 3, 4, '5', '8']

It means we need some strategy(so that sorted could treat our string items as an ints) to achieve this. This is why the key keyword argument is used. Please look at the below one.

>>> nums = ["2", 1, 3, 4, "5", "8", "-1", "-10"]
>>> sorted(nums, key=int)
['-10', '-1', 1, '2', 3, 4, '5', '8']
>>> 

Lets use lambda function as a value of key

>>> names = ["Rishikesh", "aman", "Ajay", "Hemkesh", "sandeep", "Darshan", "Virendra", "Shwetabh"]
>>> names2 = sorted(names)
>>> names2
['Ajay', 'Darshan', 'Hemkesh', 'Rishikesh', 'Shwetabh', 'Virendra', 'aman', 'sandeep']
>>> # But I don't want this o/p(here our intention is to treat 'a' same as 'A')
...
>>> names3 = sorted(names, key=lambda name:name.lower())
>>> names3
['Ajay', 'aman', 'Darshan', 'Hemkesh', 'Rishikesh', 'sandeep', 'Shwetabh', 'Virendra']
>>>

You can define your own function(callable) and provide it as value of key.

Dear programers, I have written the below code for you, just try to understand it and comment your explanation. I would be glad to see your explanation(it's simple).

>>> def validator(item):
...     try:
...         return int(item)
...     except:
...         return 0
... 
>>> sorted(['gurmit', "0", 5, 2, 1, "front", -2, "great"], key=validator)
[-2, 'gurmit', '0', 'front', 'great', 1, 2, 5]
>>>

I hope it would be useful.

For debug purposes only, you can call _viewDelegate on views to get their view controllers. This is private API, so not safe for App Store, but for debugging it is useful.

Other useful methods:

• _viewControllerForAncestor - get the first controller that manages a view in the superview chain. (thanks n00neimp0rtant)
• _rootAncestorViewController - get the ancestor controller whose view hierarchy is set in the window currently.

If you want to move the position of the legend please use the following code:

library(reshape2) # for melt
df <- melt(outer(1:4, 1:4), varnames = c("X1", "X2"))
p1 <- ggplot(df, aes(X1, X2)) + geom_tile(aes(fill = value))
p1 + scale_fill_continuous(guide = guide_legend()) +
    theme(legend.position="bottom")

This should give you the desired result.

Yes, you can use GT for free. See the post with explanation. And look at repo on GitHub.

UPD 19.03.2019 Here is a version for browser on GitHub.

I got this same error and using a primary key did not make a difference. The issue was that the table is a linked Excel table. I know there are settings to change this but my IT department has locked this so we cant change it. Instead, I created a make table from the linked table and used that instead in my Update Query and it worked. Note, any queries in your query that are also linked to the same Excel linked table will cause the same error so you will need to change these as well so they are not directly linked to the Excel linked table. HTH

Resized VM with more memory fixed this issue.

@martinho as a newbie using Flask and Python myself, I think the previous answers here took for granted that you had a good understanding of the fundamentals. In case you or other viewers don't know the fundamentals, I'll give more context to understand the answer...

... the request.args is bringing a "dictionary" object for you. The "dictionary" object is similar to other collection-type of objects in Python, in that it can store many elements in one single object. Therefore the answer to your question

And how many parameters request.args.get() takes.

It will take only one object, a "dictionary" type of object (as stated in the previous answers). This "dictionary" object, however, can have as many elements as needed... (dictionaries have paired elements called Key, Value).

Other collection-type of objects besides "dictionaries", would be "tuple", and "list"... you can run a google search on those and "data structures" in order to learn other Python fundamentals. This answer is based Python; I don't have an idea if the same applies to other programming languages.

You should use readfile():

readfile("/path/to/file");

This will read the file and send it to the browser in one command. This is essentially the same as:

echo file_get_contents("/path/to/file");

except that file_get_contents() may cause the script to crash for large files, while readfile() won't.

Another workaround might be to use <div> of the same size to wrap the <svg>. After that, you will be able to apply "background-color", and "background-image" that will affect thesvg.

<div class="background">
  <svg></svg>
</div>

<style type="text/css">
.background{
  background-color: black; 
  /*background-image: */
}
</style>

Yes, using custom tags. Example in Python, making the !join tag join strings in an array:

import yaml

## define custom tag handler
def join(loader, node):
    seq = loader.construct_sequence(node)
    return ''.join([str(i) for i in seq])

## register the tag handler
yaml.add_constructor('!join', join)

## using your sample data
yaml.load("""
paths:
    root: &BASE /path/to/root/
    patha: !join [*BASE, a]
    pathb: !join [*BASE, b]
    pathc: !join [*BASE, c]
""")

Which results in:

{
    'paths': {
        'patha': '/path/to/root/a',
        'pathb': '/path/to/root/b',
        'pathc': '/path/to/root/c',
        'root': '/path/to/root/'
     }
}

The array of arguments to !join can have any number of elements of any data type, as long as they can be converted to string, so !join [*a, "/", *b, "/", *c] does what you would expect.

If you are using this form of the branch command (with start point), it does not matter where your HEAD is.

What you are doing:

git checkout dev
git branch test 07aeec983bfc17c25f0b0a7c1d47da8e35df7af8

• First, you set your HEAD to the branch dev,

• Second, you start a new branch on commit 07aeec98. There is no bb.txt at this commit (according to your github repo).

If you want to start a new branch at the location you have just checked out, you can either run branch with no start point:

git branch test

or as other have answered, branch and checkout there in one operation:

git checkout -b test

I think that you might be confused by that fact that 07aeec98 is part of the branch dev. It is true that this commit is an ancestor of dev, its changes are needed to reach the latest commit in dev. However, they are other commits that are needed to reach the latest dev, and these are not necessarily in the history of 07aeec98.

8480e8ae (where you added bb.txt) is for example not in the history of 07aeec98. If you branch from 07aeec98, you won't get the changes introduced by 8480e8ae.

In other words: if you merge branch A and branch B into branch C, then create a new branch on a commit of A, you won't get the changes introduced in B.

Same here, you had two parallel branches master and dev, which you merged in dev. Branching out from a commit of master (older than the merge) won't provide you with the changes of dev.

If you want to permanently integrate new changes from master into your feature branches, you should merge master into them and go on. This will create merge commits in your feature branches, though.

If you have not published your feature branches, you can also rebase them on the updated master: git rebase master featureA. Be prepared to solve possible conflicts.

If you want a workflow where you can work on feature branches free of merge commits and still integrate with newer changes in master, I recommend the following:

• base every new feature branch on a commit of master
• create a dev branch on a commit of master
• when you need to see how your feature branch integrates with new changes in master, merge both master and the feature branch into dev.

Do not commit into dev directly, use it only for merging other branches.

For example, if you are working on feature A and B:

a---b---c---d---e---f---g -master
    \       \
     \       \-x -featureB
      \
       \-j---k -featureA

Merge branches into a dev branch to check if they work well with the new master:

a---b---c---d---e---f---g -master
    \       \            \
     \       \            \--x'---k' -dev
      \       \             /    /   
       \       \-x----------    /    -featureB
        \                      /
         \-j---k--------------- -featureA

You can continue working on your feature branches, and keep merging in new changes from both master and feature branches into dev regularly.

a---b---c---d---e---f---g---h---i----- -master
    \       \            \            \
     \       \            \--x'---k'---i'---l' -dev
      \       \             /    /         /
       \       \-x----------    /         /  -featureB
        \                      /         /  
         \-j---k-----------------l------ -featureA

When it is time to integrate the new features, merge the feature branches (not dev!) into master.

You can write your query like so:

SELECT * FROM MyTable WHERE (A LIKE '%text1%' OR A LIKE '%text2%')

The % is a wildcard, meaning that it searches for all rows where column A contains either text1 or text2

The practical use of this construct? It is a javascript replaceAll() on strings.

var s = 'stackoverflow_is_cool';  
s = s.split('_').join(' ');  
console.log(s);

will output:

stackoverflow is cool

This answer is not exactly to this question. But I will add this since this question still searchable for how to add/deduct period from date.

$date = new DateTime('now');
$date->modify('+3 month'); // or you can use '-90 day' for deduct
$date = $date->format('Y-m-d h:i:s');
echo $date;

Walkthrough of creating and deleting an environment variable in bash:

Test if the DUALCASE variable exists:

el@apollo:~$ env | grep DUALCASE
el@apollo:~$ 

It does not, so create the variable and export it:

el@apollo:~$ DUALCASE=1
el@apollo:~$ export DUALCASE

Check if it is there:

el@apollo:~$ env | grep DUALCASE
DUALCASE=1

It is there. So get rid of it:

el@apollo:~$ unset DUALCASE

Check if it's still there:

el@apollo:~$ env | grep DUALCASE
el@apollo:~$ 

The DUALCASE exported environment variable is deleted.

Extra commands to help clear your local and environment variables:

Unset all local variables back to default on login:

el@apollo:~$ CAN="chuck norris"
el@apollo:~$ set | grep CAN
CAN='chuck norris'
el@apollo:~$ env | grep CAN
el@apollo:~$
el@apollo:~$ exec bash
el@apollo:~$ set | grep CAN
el@apollo:~$ env | grep CAN
el@apollo:~$

exec bash command cleared all the local variables but not environment variables.

Unset all environment variables back to default on login:

el@apollo:~$ export DOGE="so wow"
el@apollo:~$ env | grep DOGE
DOGE=so wow
el@apollo:~$ env -i bash
el@apollo:~$ env | grep DOGE
el@apollo:~$

env -i bash command cleared all the environment variables to default on login.

Here are the options described in @diegows's answer, described in more detail, from the documentation:

openssl req -x509 -newkey rsa:2048 -keyout key.pem -out cert.pem -days XXX

req

PKCS#10 certificate request and certificate generating utility.

-x509

this option outputs a self signed certificate instead of a certificate request. This is typically used to generate a test certificate or a self signed root CA.

-newkey arg

this option creates a new certificate request and a new private key. The argument takes one of several forms. rsa:nbits, where nbits is the number of bits, generates an RSA key nbits in size.

-keyout filename

this gives the filename to write the newly created private key to.

-out filename

This specifies the output filename to write to or standard output by default.

-days n

when the -x509 option is being used this specifies the number of days to certify the certificate for. The default is 30 days.

-nodes

if this option is specified then if a private key is created it will not be encrypted.

The documentation is actually more detailed than the above; I just summarized it here.

I'd go with the default arguments, especially since C++ doesn't let you chain constructors (so you end up having to duplicate the initialiser list, and possibly more, for each overload).

That said, there are some gotchas with default arguments, including the fact that constants may be inlined (and thereby become part of your class' binary interface). Another to watch out for is that adding default arguments can turn an explicit multi-argument constructor into an implicit one-argument constructor:

class Vehicle {
public:
  Vehicle(int wheels, std::string name = "Mini");
};

Vehicle x = 5;  // this compiles just fine... did you really want it to?

Pass by pointer is the only way you could pass "by reference" in C, so you still see it used quite a bit.

The NULL pointer is a handy convention for saying a parameter is unused or not valid, so use a pointer in that case.

References can't be updated once they're set, so use a pointer if you ever need to reassign it.

Prefer a reference in every case where there isn't a good reason not to. Make it const if you can.

Yes, I read all the answers. However, if you are me and have been pulling out all of what's left of your hair, then try checking the \bin folder. Like most proj files might have several configurations grouped under the XML element PropertyGroup, then I changed the OutputPath value from 'bin\Debug' to remove the '\Debug' part and Rebuild. This placed the files in the \bin folder allowing the Express IIS to find and load the build. I am left wondering what is the correct way to manage these different builds so that a local debug deploy is able to find and load the target environment.

• I would suggest you to extract the table using tabula.
• Pass your pdf as an argument to the tabula api and it will return you the table in the form of dataframe.
• Each table in your pdf is returned as one dataframe.
• The table will be returned in a list of dataframea, for working with dataframe you need pandas.

This is my code for extracting pdf.

import pandas as pd
import tabula
file = "filename.pdf"
path = 'enter your directory path here'  + file
df = tabula.read_pdf(path, pages = '1', multiple_tables = True)
print(df)

Please refer to this repo of mine for more details.

Instead of putting int( ), put float( ) which will let you use decimals along with integers.

This CSS seems to work in Safari and Chrome:

div#div2
{
-webkit-transform:rotate(90deg); /* Chrome, Safari, Opera */
transform:rotate(90deg); /* Standard syntax */
}

and in the body:

<div id="div2"><img src="image.jpg"  ></div>

But this (and the .rotate90 example above) pushes the rotated image higher up on the page than if it were un-rotated. Not sure how to control placement of the image relative to text or other rotated images.
