For Swift 3+ and Xcode 9+ Try using this

extension ViewController: UICollectionViewDelegateFlowLayout {

func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {

    let collectionWidth = collectionView.bounds.width
    return CGSize(width: collectionWidth/3, height: collectionWidth/3)

}

func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, minimumLineSpacingForSectionAt section: Int) -> CGFloat {
    return 0
}

func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, minimumInteritemSpacingForSectionAt section: Int) -> CGFloat {
    return 0

}

For now I just switched registry URL from https to http. Like this:

npm config set registry="http://registry.npmjs.org/"

In my case I was adding the buttons dynamically so my solution required some XML part and some Java part. I had to find and mix solutions from a few different places and thought I will share it here so someone else looking for the similar solution might find it helpful.

First part of my layout file XML...

<android.support.v7.widget.GridLayout
    xmlns:grid="http://schemas.android.com/apk/res-auto"
    android:id="@+id/gl_Options"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    grid:useDefaultMargins="true">
</android.support.v7.widget.GridLayout>

grid:useDefaultMargins="true" is not required but I added because that looked better to me, you may apply other visual affects (e.g. padding) as mentioned in some answers here. Now for the buttons as I have to add them dynamically. Here is the Java part of my code to make these buttons, I am including only those lines related to this context. Assume I have to make buttons from as many myOptions are available to my code and I am not copying the OnClickListener code as well.

import android.support.v7.widget.GridLayout;   //Reference to Library

public class myFragment extends Fragment{
    GridLayout gl_Options;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        gl_AmountOptions = (GridLayout)view.findViewById( R.id.gl_AmountOptions );
        ...
        gl_Options.removeAllViews();     // Remove all existing views
        gl_AmountOptions.setColumnCount( myOptions.length <= 9 ? 3: 4 );  // Set appropriate number of columns

        for( String opt : myOptions ) {
            GridLayout.LayoutParams lParams   = new GridLayout.LayoutParams( GridLayout.spec( GridLayout.UNDEFINED, 1f), GridLayout.spec( GridLayout.UNDEFINED, 1f));
            // The above defines LayoutParameters as not specified Column and Row with grid:layout_columnWeight="1" and grid:layout_rowWeight="1"
            lParams.width = 0;    // Setting width to "0dp" so weight is applied instead

            Button b = new Button(this.getContext());
            b.setText( opt );
            b.setLayoutParams(lParams);
            b.setOnClickListener( myClickListener );
            gl_Options.addView( b );
        }
    }
}

As we are using GridLayout from support library and not the standard GridLayout, we have to tell grade about that in YourProject.grade file.

dependencies {
    compile 'com.android.support:appcompat-v7:23.4.0'
    ...
    compile 'com.android.support:gridlayout-v7:23.4.0'
}

When you push to a remote and you use the --set-upstream flag git sets the branch you are pushing to as the remote tracking branch of the branch you are pushing.

Adding a remote tracking branch means that git then knows what you want to do when you git fetch, git pull or git push in future. It assumes that you want to keep the local branch and the remote branch it is tracking in sync and does the appropriate thing to achieve this.

You could achieve the same thing with git branch --set-upstream-to or git checkout --track. See the git help pages on tracking branches for more information.

I was experiencing a similar problem running (and trying to debug) two different Django applications on the same machine.

I was running them with these commands:

./manage.py runserver 8000
./manage.py runserver 8001

When I did login in the first one and then in the second one I always got logged out the first one and viceversa.

I added this on my /etc/hosts

127.0.0.1    app1
127.0.0.1    app2

Then I started the two apps with these commands:

./manage.py runserver app1:8000
./manage.py runserver app2:8001

Problem solved :)

The PID is stored in $$.

Example: kill -9 $$ will kill the shell instance it is called from.

You can try this force-download script. Even if you don't use it, it'll probably point you in the right direction:

<?php

$filename = $_GET['file'];

// required for IE, otherwise Content-disposition is ignored
if(ini_get('zlib.output_compression'))
  ini_set('zlib.output_compression', 'Off');

// addition by Jorg Weske
$file_extension = strtolower(substr(strrchr($filename,"."),1));

if( $filename == "" ) 
{
  echo "<html><title>eLouai's Download Script</title><body>ERROR: download file NOT SPECIFIED. USE force-download.php?file=filepath</body></html>";
  exit;
} elseif ( ! file_exists( $filename ) ) 
{
  echo "<html><title>eLouai's Download Script</title><body>ERROR: File not found. USE force-download.php?file=filepath</body></html>";
  exit;
};
switch( $file_extension )
{
  case "pdf": $ctype="application/pdf"; break;

HTTP status code 500 usually means that the webserver code has crashed. You need to determine the status code beforehand using HttpURLConnection#getResponseCode() and in case of errors, read the HttpURLConnection#getErrorStream() instead. It may namely contain information about the problem.

If the host has blocked you, you would rather have gotten a 4nn status code like 401 or 403.

I've just been banging my head against a wall trying to solve a bug because I read this page and concluded there was no meaningful difference when in practice there is so I'll post this link here in case anyone else finds they get different results out of == and equals.

Object == equality fails, but .Equals succeeds. Does this make sense?

string a = "x";
string b = new String(new []{'x'});

Console.WriteLine("x == x " + (a == b));//True
Console.WriteLine("object x == x " + ((object)a == (object)b));//False
Console.WriteLine("x equals x " + (a.Equals(b)));//True
Console.WriteLine("object x equals x " + (((object)a).Equals((object)b)));//True

For a non-recursive delete (using du and awk):

rm `du * | awk '$1 == "0" {print $2}'`

With the property (highlighted) I can get the instance of the MainForm class. But this is a good practice? What do you recommend?

For this I use the property MainFormInstance that runs on the OnLoad method.

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using LightInfocon.Data.LightBaseProvider;
using System.Configuration;

namespace SINJRectifier
{

    public partial class MainForm : Form
    {
        public MainForm()
        {
            InitializeComponent();
        }

        protected override void OnLoad(EventArgs e)
        {
            UserInterface userInterfaceObj = new UserInterface();
            this.chklbBasesList.Items.AddRange(userInterfaceObj.ExtentsList(this.chklbBasesList));
            MainFormInstance.MainFormInstanceSet = this; //Here I get the instance
        }

        private void btnBegin_Click(object sender, EventArgs e)
        {
            Maestro.ConductSymphony();
            ErrorHandling.SetExcecutionIsAllow();
        }
    }

    static class MainFormInstance  //Here I get the instance
    {
        private static MainForm mainFormInstance;

        public static MainForm MainFormInstanceSet { set { mainFormInstance = value; } }

        public static MainForm MainFormInstanceGet { get { return mainFormInstance; } }
    }
}

This confusion is because URL is still 'broken' to this day

Take "http://www.google.com" for instance. This is a URL. A URL is a Uniform Resource Locator and is really a pointer to a web page (in most cases). URLs actually have a very well-defined structure since the first specification in 1994.

We can extract detailed information about the "http://www.google.com" URL:

+---------------+-------------------+   
|      Part     |      Data         |   
+---------------+-------------------+   
|  Scheme       | http              |   
|  Host address | www.google.com    |   
+---------------+-------------------+  

If we look at a more complex URL such as "https://bob:[email protected]:8080/file;p=1?q=2#third" we can extract the following information:

+-------------------+---------------------+
|        Part       |       Data          |
+-------------------+---------------------+
|  Scheme           | https               |
|  User             | bob                 |
|  Password         | bobby               |
|  Host address     | www.lunatech.com    |
|  Port             | 8080                |
|  Path             | /file               |
|  Path parameters  | p=1                 |
|  Query parameters | q=2                 |
|  Fragment         | third               |
+-------------------+---------------------+

The reserved characters are different for each part

For HTTP URLs, a space in a path fragment part has to be encoded to "%20" (not, absolutely not "+"), while the "+" character in the path fragment part can be left unencoded.

Now in the query part, spaces may be encoded to either "+" (for backwards compatibility: do not try to search for it in the URI standard) or "%20" while the "+" character (as a result of this ambiguity) has to be escaped to "%2B".

This means that the "blue+light blue" string has to be encoded differently in the path and query parts: "http://example.com/blue+light%20blue?blue%2Blight+blue". From there you can deduce that encoding a fully constructed URL is impossible without a syntactical awareness of the URL structure.

What this boils down to is

you should have %20 before the ? and + after

Source

You can also do this with ant contrib's if task.

<if>
    <equals arg1="${condition}" arg2="true"/>
    <then>
        <copy file="${some.dir}/file" todir="${another.dir}"/>
    </then>
    <elseif>
        <equals arg1="${condition}" arg2="false"/>
        <then>
            <copy file="${some.dir}/differentFile" todir="${another.dir}"/>
        </then>
    </elseif>
    <else>
        <echo message="Condition was neither true nor false"/>
    </else>
</if>

If you want to get stdout and stderr back (including extracting it from the CalledProcessError in the event that one occurs), use the following:

import subprocess

command = ["ls", "-l"]
try:
    output = subprocess.check_output(command, stderr=subprocess.STDOUT).decode()
    success = True 
except subprocess.CalledProcessError as e:
    output = e.output.decode()
    success = False

print(output)

This is Python 2 and 3 compatible.

If your command is a string rather than an array, prefix this with:

import shlex
command = shlex.split(command)

I am using MEANJS 0.6.0 with [email protected], it's good

Client:

Controller:

var input = { keyword: vm.keyword };
ProductAPi.getOrder(input)

services:

this.getOrder = function (input) {return $http.get('/api/order', { params: input });};

Server

routes

app.route('/api/order').get(products.order);

controller

exports.order = function (req, res) {
  var keyword = req.query.keyword
  ...

For special character set, you need to check UNICODE Charts. After choose your character, you can use sql statement below,

SELECT COMPOSE('do' || UNISTR('\0304' || 'TTTT')) FROM dual;

--

doTTTT

Yet another solution (Monday is the first day):

select 
    to_char(sysdate - to_char(sysdate, 'd') + 2, 'yyyymmdd') first_day_of_week
    , to_char(sysdate - to_char(sysdate, 'd') + 8, 'yyyymmdd') last_day_of_week
from
    dual

Also you can use the following command:

git push -u origin master

This creates (-u) another branch in your remote repo. Once the authentication using ssh is done that is.

I believe I have a much simpeler solution for this.

public class MyFragment extends Fragment{

   private String mTitle;
   private List<MyObject> mObjects;

   public static MyFragment newInstance(String title, List<MyObject> objects)
   MyFragment myFrag = new MyFragment();
   myFrag.mTitle = title;
   myFrag.mObjects = objects;
   return myFrag;
   }

There's a convenient method for this in MySql called GROUP_CONCAT. An equivalent for SQL Server doesn't exist, but you can write your own using the SQLCLR. Luckily someone already did that for you.

Your query then turns into this (which btw is a much nicer syntax):

SELECT CUSTOMFIELD, ISSUE, dbo.GROUP_CONCAT(STRINGVALUE)
FROM Jira.customfieldvalue
WHERE CUSTOMFIELD = 12534 AND ISSUE = 19602
GROUP BY CUSTOMFIELD, ISSUE

But please note that this method is good for at the most 100 rows within a group. Beyond that, you'll have major performance problems. SQLCLR aggregates have to serialize any intermediate results and that quickly piles up to quite a lot of work. Keep this in mind!

Interestingly the FOR XML doesn't suffer from the same problem but instead uses that horrendous syntax.

You can also specify the exact values for each gr

0 2,10,12,14,16,18,20 * * *

It stands for 2h00, 10h00, 12h00 and so on, till 20h00.

From the above answer, we have:

The comma, ",", means "and". If you are confused by the above line, remember that spaces are the field separators, not commas.

And from (Wikipedia page):

*    *    *    *    *  command to be executed
-    -    -    -    -
¦    ¦    ¦    ¦    ¦
¦    ¦    ¦    ¦    ¦
¦    ¦    ¦    ¦    +----- day of week (0 - 7) (0 or 7 are Sunday, or use names)
¦    ¦    ¦    +---------- month (1 - 12)
¦    ¦    +--------------- day of month (1 - 31)
¦    +-------------------- hour (0 - 23)
+------------------------- min (0 - 59)

Hope it helps :)

EDIT:

• don't miss the 1st 0 (zero) and the following space: it means "the minute zero", you can also set it to 15 (the 15th minute) or expressions like */15 (every minute divisible by 15, i.e. 0,15,30)

The "break" command does not work within an "if" statement.

If you remove the "break" command from your code and then test the code, you should find that the code works exactly the same without a "break" command as with one.

"Break" is designed for use inside loops (for, while, do-while, enhanced for and switch).

I like this solution from a similar question. https://stackoverflow.com/a/25036303/2364401 Use bootstraps text-center class on the actual table data <td> and table header <th> elements. So

and

input[name] Inputs elements with name property.

[id|=view] Elements with id that start with view-.

[class~=button] Elements with the button class.

In header.php insert this code to show menu:

    }

    function end_el( &$output, $item, $depth = 0, $args = array() ) {
        echo '</a></li>';
    }
}

I had something else, the files itself where inaccessible in a SBS envirenment.

Delete the files in the config folder (if you can't open them!) and replace them with a copy of the folder on your own local pc.

Fixed it for me :)

You have to specify the projectBaseDir if the module name doesn't match you module directory.

Since both your module are located in ".", you can simply add the following to your sonar-project properties:

module1.sonar.projectBaseDir=.
module2.sonar.projectBaseDir=.

Sonar will handle your modules as components of the project:

EDIT

If both of your modules are located in the same source directory, define the same source folder for both and exclude the unwanted packages with sonar.exclusions:

module1.sonar.sources=src/main/java
module1.sonar.exclusions=app2code/**/*

module2.sonar.sources=src/main/java
module2.sonar.exclusions=app1code/**/*

You need a little statistical knowledge to see this. R squared between two vectors is just the square of their correlation. So you can define you function as:

rsq <- function (x, y) cor(x, y) ^ 2

Sandipan's answer will return you exactly the same result (see the following proof), but as it stands it appears more readable (due to the evident $r.squared).

Let's do the statistics

Basically we fit a linear regression of y over x, and compute the ratio of regression sum of squares to total sum of squares.

lemma 1: a regression y ~ x is equivalent to y - mean(y) ~ x - mean(x)

lemma 2: beta = cov(x, y) / var(x)

lemma 3: R.square = cor(x, y) ^ 2

Warning

R squared between two arbitrary vectors x and y (of the same length) is just a goodness measure of their linear relationship. Think twice!! R squared between x + a and y + b are identical for any constant shift a and b. So it is a weak or even useless measure on "goodness of prediction". Use MSE or RMSE instead:

• How to obtain RMSE out of lm result?
• R - Calculate Test MSE given a trained model from a training set and a test set

I agree with 42-'s comment:

The R squared is reported by summary functions associated with regression functions. But only when such an estimate is statistically justified.

R squared can be a (but not the best) measure of "goodness of fit". But there is no justification that it can measure the goodness of out-of-sample prediction. If you split your data into training and testing parts and fit a regression model on the training one, you can get a valid R squared value on training part, but you can't legitimately compute an R squared on the test part. Some people did this, but I don't agree with it.

Here is very extreme example:

preds <- 1:4/4
actual <- 1:4

The R squared between those two vectors is 1. Yes of course, one is just a linear rescaling of the other so they have a perfect linear relationship. But, do you really think that the preds is a good prediction on actual??

In reply to wordsforthewise

Thanks for your comments 1, 2 and your answer of details.

You probably misunderstood the procedure. Given two vectors x and y, we first fit a regression line y ~ x then compute regression sum of squares and total sum of squares. It looks like you skip this regression step and go straight to the sum of square computation. That is false, since the partition of sum of squares does not hold and you can't compute R squared in a consistent way.

As you demonstrated, this is just one way for computing R squared:

preds <- c(1, 2, 3)
actual <- c(2, 2, 4)
rss <- sum((preds - actual) ^ 2)  ## residual sum of squares
tss <- sum((actual - mean(actual)) ^ 2)  ## total sum of squares
rsq <- 1 - rss/tss
#[1] 0.25

But there is another:

regss <- sum((preds - mean(preds)) ^ 2) ## regression sum of squares
regss / tss
#[1] 0.75

Also, your formula can give a negative value (the proper value should be 1 as mentioned above in the Warning section).

preds <- 1:4 / 4
actual <- 1:4
rss <- sum((preds - actual) ^ 2)  ## residual sum of squares
tss <- sum((actual - mean(actual)) ^ 2)  ## total sum of squares
rsq <- 1 - rss/tss
#[1] -2.375

Final remark

I had never expected that this answer could eventually be so long when I posted my initial answer 2 years ago. However, given the high views of this thread, I feel obliged to add more statistical details and discussions. I don't want to mislead people that just because they can compute an R squared so easily, they can use R squared everywhere.

Nianliang's solution turned out so useful from my Vagrant ubunuto, thart I ended up adding these 2 commands to my /etc/init.d/mongodb file:

.
.
.    
start|stop|restart)
        rm /var/lib/mongodb/mongod.lock
        mongod --repair
.
.
.

checked the program and the results are as,

p++;    // use it then move to next int position
++p;    // move to next int and then use it
++*p;   // increments the value by 1 then use it 
++(*p); // increments the value by 1 then use it
++*(p); // increments the value by 1 then use it
*p++;   // use the value of p then moves to next position
(*p)++; // use the value of p then increment the value
*(p)++; // use the value of p then moves to next position
*++p;   // moves to the next int location then use that value
*(++p); // moves to next location then use that value

You can use the visual mode also (some commands are usable with the delete option also) vip vap to select paragraph, v2ap to select two paragraphs dap works, d2ap also. You can delete within blocks of [ ] like da[

For reference: the types of objects. From vim documentation : section 4. http://vimdoc.sourceforge.net/htmldoc/visual.html

4. Operating on the Visual area             *visual-operators*

...    
The objects that can be used are:

iw  inner word                  
aW  a WORD (with white space)

Try this : Using this you can select data from last 30 days

SELECT
    *
FROM
    product
WHERE
    purchase_date > DATE_SUB(CURDATE(), INTERVAL 1 MONTH)

You can execute this in 2 simple statements:

row.names(samp) <- samp$names
samp[1] <- NULL

today is 29th of January, +1 month means 29th of Fabruary, but because February consists of 28 days this year, it overlaps to the next day which is March 1st

instead try

strtotime('next month')

Personally I like the sub-classing of the view + drawRect, but here's just another way of going about it (and it kind of works along the same lines as the accepted answer by @If Pollavith):

Your new border layer can be set up to have whatever dimensions you like. So, like @If Pollavith's answer, you create a layer to be as tall as you want it to be, and as wide as the view you want to have bordered. Use the layer's frame definition to place it where you want it, and then add it as a sub-layer to your view.

For reference, my own requirement was to put a border on the LEFT-HAND side of the view (please don't cut and paste this code and dis' me just 'cos it doesn't put a border at the top of the view -- modifying the code below is simple enough):

    CALayer *leftBorder = [CALayer layer];
leftBorder.borderColor = [UIColor colorWithRed:0.0 green:91.0/255.0 blue:141.0/255.0 alpha:1.0].CGColor;
leftBorder.borderWidth = 1;
leftBorder.frame = CGRectMake(0, 0, 1.0, CGRectGetHeight(self.myTargetView.frame));
[self.myTargetView.layer addSublayer:leftBorder];

I guess the only moderate benefit over this and making a small UIView or UILabel is that the CALayer is supposedly 'lighter-weight', and there's a lot of interesting views (as in opinions) about over-riding drawRect versus using CALayers (like here: iOS: Using UIView's 'drawRect:' vs. its layer's delagate 'drawLayer:inContext:').

I like the colour blue.

Is your link to another web page? If so, perhaps you could put the variable in the query string and set the session variable when the page being linked to is loaded.

So the link looks like this:

<a href="home.php?variable=value" name="home">home</a>

And the homge page would parse the query string and set the session variable.

Add set nocount on to the beginning of the stored proc (if you're on SQL Server). I just solved this problem in my own work and it was caused by intermediate results, such as "1203 Rows Affected", being loaded into the Recordset I was trying to use.

You can check an example in Plunker over here plunker example filters

filter() {

    let storeId = 1;
    this.bookFilteredList = this.bookList
                                .filter((book: Book) => book.storeId === storeId);
    this.bookList = this.bookFilteredList; 
}

Open a new worksheet on the related instance (Alt-F10) and run the following query

SELECT view_name, owner
FROM sys.all_views 
ORDER BY owner, view_name

I like this a lot better. reduces the if/switch, just do.

private enum Alignment { LEFT, RIGHT;

void process() {
//Process it...
} 
};    
String drawCellValue (int maxCellLength, String cellValue, Alignment align){
  align.process();
}

of course, it can be:

String process(...) {
//Process it...
} 

From the release news of ggplot 2.2.0: "The main plot title is now left-aligned to better work better with a subtitle". See also the plot.title argument in ?theme: "left-aligned by default".

As pointed out by @J_F, you may add theme(plot.title = element_text(hjust = 0.5)) to center the title.

ggplot() +
  ggtitle("Default in 2.2.0 is left-aligned")

ggplot() +
  ggtitle("Use theme(plot.title = element_text(hjust = 0.5)) to center") +
  theme(plot.title = element_text(hjust = 0.5))

That's no struts related problem but rather plain HMTL/CSS.

I'm not HTML or CSS expert, but I guess you could use a div with a border on the left or right side only.

I guess the below should work (instead of the writer part from your example). I'm unfortunately with no build environment so It's from memory but I hope it helps

using (var fs = File.Open(filePath, FileMode.Open, FileAccess.ReadWrite)))
        {
            var destinationReader = StreamReader(fs);
            var writer = StreamWriter(fs);
            while ((line = reader.ReadLine()) != null)
            {
              if (line_number == line_to_edit)
                {
                    writer.WriteLine(lineToWrite);
                }
                else
                {
                    destinationReader .ReadLine();
                }
                line_number++;
            }
        }

You may also want to look at rsync if you're doing a lot of files.

If you're going to making a lot of changes and want to keep your directories and files in sync, you may want to use a version control system like Subversion or Git. See http://xoa.petdance.com/How_to:_Keep_your_home_directory_in_Subversion

You can create a SqlCommand with CommandText equal to

INSERT INTO aspnet_GameProfiles(UserId, GameId) OUTPUT INSERTED.ID VALUES(@UserId, @GameId)

and execute int id = (int)command.ExecuteScalar.

This MSDN article will give you some additional techniques.

I would use a regex:

import re
new_list = [re.sub(r"\.(?=[^.]*$)", r". - ", s) for s in old_list]

All that is needed is "#,0.00", c# does the rest.

Num.ToString("#,0.00"")

• The "#,0" formats the thousand separators
• "0.00" forces two decimal points

Bit less elegant but can also do:

DOM stands for Document Object Model. It is the W3C(World Wide Web Consortium) Standard. It define standard for accessing and manipulating HTML and XML document and The elements of DOM is head,title,body tag etc. So the answer of your first statement is

Statement #1 You can add multiple classes to a single DOM element.

Explanation : "div class="cssclass1 cssclass2 cssclass3"

Here tag is element of DOM and i have applied multiple classes to DOM element.

Adding a separate answer because it is radically different.

You could use rgba and set the alpha channel low (to get transparency) to make your drop shadow less noticeable.

Try something like this (play with the .5)

-webkit-box-shadow: 0px -4px 7px rbga(230, 230, 230, .5);
-moz-box-shadow: 0px -4px 7px rbga(230, 230, 230, .5);
box-shadow: 0px -4px 7px rbga(230, 230, 230, .5);

Hope this helps!

You can use a lambda:

Collectors.toMap(p -> p.getLast(), Function.identity())

or, more concisely, you can use a method reference using :::

Collectors.toMap(Person::getLast, Function.identity())

and instead of Function.identity, you can simply use the equivalent lambda:

Collectors.toMap(Person::getLast, p -> p)

If you use Netbeans you should get hints whenever an anonymous class can be replaced by a lambda.

If you are stuck with C++98 and don't want to use boost, here there is the solution I use when I need to initialize a static map:

typedef std::pair< int, char > elemPair_t;
elemPair_t elemPairs[] = 
{
    elemPair_t( 1, 'a'), 
    elemPair_t( 3, 'b' ), 
    elemPair_t( 5, 'c' ), 
    elemPair_t( 7, 'd' )
};

const std::map< int, char > myMap( &elemPairs[ 0 ], &elemPairs[ sizeof( elemPairs ) / sizeof( elemPairs[ 0 ] ) ] );

Try this:

if ( jQuery('#postageyes').is(':checked') ){ ... }

If you add helper fields to the coordinates table, you can improve response time of the query.

Like this:

CREATE TABLE `Coordinates` (
`id` INT(10) UNSIGNED NOT NULL COMMENT 'id for the object',
`type` TINYINT(4) UNSIGNED NOT NULL DEFAULT '0' COMMENT 'type',
`sin_lat` FLOAT NOT NULL COMMENT 'sin(lat) in radians',
`cos_cos` FLOAT NOT NULL COMMENT 'cos(lat)*cos(lon) in radians',
`cos_sin` FLOAT NOT NULL COMMENT 'cos(lat)*sin(lon) in radians',
`lat` FLOAT NOT NULL COMMENT 'latitude in degrees',
`lon` FLOAT NOT NULL COMMENT 'longitude in degrees',
INDEX `lat_lon_idx` (`lat`, `lon`)
)    

If you're using TokuDB, you'll get even better performance if you add clustering indexes on either of the predicates, for example, like this:

alter table Coordinates add clustering index c_lat(lat);
alter table Coordinates add clustering index c_lon(lon);

You'll need the basic lat and lon in degrees as well as sin(lat) in radians, cos(lat)*cos(lon) in radians and cos(lat)*sin(lon) in radians for each point. Then you create a mysql function, smth like this:

CREATE FUNCTION `geodistance`(`sin_lat1` FLOAT,
                              `cos_cos1` FLOAT, `cos_sin1` FLOAT,
                              `sin_lat2` FLOAT,
                              `cos_cos2` FLOAT, `cos_sin2` FLOAT)
    RETURNS float
    LANGUAGE SQL
    DETERMINISTIC
    CONTAINS SQL
    SQL SECURITY INVOKER
   BEGIN
   RETURN acos(sin_lat1*sin_lat2 + cos_cos1*cos_cos2 + cos_sin1*cos_sin2);
   END

This gives you the distance.

Don't forget to add an index on lat/lon so the bounding boxing can help the search instead of slowing it down (the index is already added in the CREATE TABLE query above).

INDEX `lat_lon_idx` (`lat`, `lon`)

Given an old table with only lat/lon coordinates, you can set up a script to update it like this: (php using meekrodb)

$users = DB::query('SELECT id,lat,lon FROM Old_Coordinates');

foreach ($users as $user)
{
  $lat_rad = deg2rad($user['lat']);
  $lon_rad = deg2rad($user['lon']);

  DB::replace('Coordinates', array(
    'object_id' => $user['id'],
    'object_type' => 0,
    'sin_lat' => sin($lat_rad),
    'cos_cos' => cos($lat_rad)*cos($lon_rad),
    'cos_sin' => cos($lat_rad)*sin($lon_rad),
    'lat' => $user['lat'],
    'lon' => $user['lon']
  ));
}

Then you optimize the actual query to only do the distance calculation when really needed, for example by bounding the circle (well, oval) from inside and outside. For that, you'll need to precalculate several metrics for the query itself:

// assuming the search center coordinates are $lat and $lon in degrees
// and radius in km is given in $distance
$lat_rad = deg2rad($lat);
$lon_rad = deg2rad($lon);
$R = 6371; // earth's radius, km
$distance_rad = $distance/$R;
$distance_rad_plus = $distance_rad * 1.06; // ovality error for outer bounding box
$dist_deg_lat = rad2deg($distance_rad_plus); //outer bounding box
$dist_deg_lon = rad2deg($distance_rad_plus/cos(deg2rad($lat)));
$dist_deg_lat_small = rad2deg($distance_rad/sqrt(2)); //inner bounding box
$dist_deg_lon_small = rad2deg($distance_rad/cos(deg2rad($lat))/sqrt(2));

Given those preparations, the query goes something like this (php):

$neighbors = DB::query("SELECT id, type, lat, lon,
       geodistance(sin_lat,cos_cos,cos_sin,%d,%d,%d) as distance
       FROM Coordinates WHERE
       lat BETWEEN %d AND %d AND lon BETWEEN %d AND %d
       HAVING (lat BETWEEN %d AND %d AND lon BETWEEN %d AND %d) OR distance <= %d",
  // center radian values: sin_lat, cos_cos, cos_sin
       sin($lat_rad),cos($lat_rad)*cos($lon_rad),cos($lat_rad)*sin($lon_rad),
  // min_lat, max_lat, min_lon, max_lon for the outside box
       $lat-$dist_deg_lat,$lat+$dist_deg_lat,
       $lon-$dist_deg_lon,$lon+$dist_deg_lon,
  // min_lat, max_lat, min_lon, max_lon for the inside box
       $lat-$dist_deg_lat_small,$lat+$dist_deg_lat_small,
       $lon-$dist_deg_lon_small,$lon+$dist_deg_lon_small,
  // distance in radians
       $distance_rad);

EXPLAIN on the above query might say that it's not using index unless there's enough results to trigger such. The index will be used when there's enough data in the coordinates table. You can add FORCE INDEX (lat_lon_idx) to the SELECT to make it use the index with no regards to the table size, so you can verify with EXPLAIN that it is working correctly.

With the above code samples you should have a working and scalable implementation of object search by distance with minimal error.

After editing .gitignore to match the ignored files, you can do git ls-files -ci --exclude-standard to see the files that are included in the exclude lists; you can then do

• Linux/MacOS: git ls-files -ci --exclude-standard -z | xargs -0 git rm --cached
• Windows (PowerShell): git ls-files -ci --exclude-standard | % { git rm --cached "$_" }
• Windows (cmd.exe): for /F "tokens=*" %a in ('git ls-files -ci --exclude-standard') do @git rm --cached "%a"

to remove them from the repository (without deleting them from disk).

Edit: You can also add this as an alias in your .gitconfig file so you can run it anytime you like. Just add the following line under the [alias] section (modify as needed for Windows or Mac):

apply-gitignore = !git ls-files -ci --exclude-standard -z | xargs -0 git rm --cached

(The -r flag in xargs prevents git rm from running on an empty result and printing out its usage message, but may only be supported by GNU findutils. Other versions of xargs may or may not have a similar option.)

Now you can just type git apply-gitignore in your repo, and it'll do the work for you!

The easiest way would be to use a GUI:

For Gnome use gnome-schedule (universe)

sudo apt-get install gnome-schedule 

For KDE use kde-config-cron

It should be pre installed on Kubuntu

But if you use a headless linux or don´t want GUI´s you may use:

crontab -e

If you type it into Terminal you´ll get a table.
You have to insert your cronjobs now.
Format a job like this:

*     *     *     *     *  YOURCOMMAND
-     -     -     -     -
|     |     |     |     |
|     |     |     |     +----- Day in Week (0 to 7) (Sunday is 0 and 7)
|     |     |     +------- Month (1 to 12)
|     |     +--------- Day in Month (1 to 31)
|     +----------- Hour (0 to 23)
+------------- Minute (0 to 59)

There are some shorts, too (if you don´t want the *):

@reboot --> only once at startup
@daily ---> once a day
@midnight --> once a day at midnight
@hourly --> once a hour
@weekly --> once a week
@monthly --> once a month
@annually --> once a year
@yearly --> once a year

If you want to use the shorts as cron (because they don´t work or so):

@daily --> 0 0 * * *
@midnight --> 0 0 * * *
@hourly --> 0 * * * *
@weekly --> 0 0 * * 0
@monthly --> 0 0 1 * *
@annually --> 0 0 1 1 *
@yearly --> 0 0 1 1 *

Very easy with the dateTime() object, too.

$tomorrow = new DateTime('tomorrow');
echo $tomorrow->format("Y-m-d"); // Tomorrow's date

$yesterday = new DateTime('yesterday');
echo $yesterday->format("Y-m-d"); // Yesterday's date

I would recommend reading in the line into a string, then splitting it based on the spaces. For this, you can use the getline(...) function. The trick is having a dynamic sized data structure to hold the strings once it's split. Probably the easiest to use would be a vector.

#include <string>
#include <vector>
...
  string rawInput;
  vector<String> numbers;
  while( getline( cin, rawInput, ' ' ) )
  {
    numbers.push_back(rawInput);
  }

So say the input looks like this:

Enter a number, or numbers separated by a space, between 1 and 1000.
10 5 20 1 200 7

You will now have a vector, numbers, that contains the elements: {"10","5","20","1","200","7"}.

Note that these are still strings, so not useful in arithmetic. To convert them to integers, we use a combination of the STL function, atoi(...), and because atoi requires a c-string instead of a c++ style string, we use the string class' c_str() member function.

while(!numbers.empty())
{
  string temp = numbers.pop_back();//removes the last element from the string
  num = atoi( temp.c_str() ); //re-used your 'num' variable from your code

  ...//do stuff
}

Now there's some problems with this code. Yes, it runs, but it is kind of clunky, and it puts the numbers out in reverse order. Lets re-write it so that it is a little more compact:

#include <string>
...
string rawInput;
cout << "Enter a number, or numbers separated by a space, between 1 and 1000." << endl;
while( getline( cin, rawInput, ' ') )
{
  num = atoi( rawInput.c_str() );
  ...//do your stuff
}

There's still lots of room for improvement with error handling (right now if you enter a non-number the program will crash), and there's infinitely more ways to actually handle the input to get it in a usable number form (the joys of programming!), but that should give you a comprehensive start. :)

Note: I had the reference pages as links, but I cannot post more than two since I have less than 15 posts :/

Edit: I was a little bit wrong about the atoi behavior; I confused it with Java's string->Integer conversions which throw a Not-A-Number exception when given a string that isn't a number, and then crashes the program if the exception isn't handled. atoi(), on the other hand, returns 0, which is not as helpful because what if 0 is the number they entered? Let's make use of the isdigit(...) function. An important thing to note here is that c++ style strings can be accessed like an array, meaning rawInput[0] is the first character in the string all the way up to rawInput[length - 1].

#include <string>
#include <ctype.h>
...
string rawInput;
cout << "Enter a number, or numbers separated by a space, between 1 and 1000." << endl;
while( getline( cin, rawInput, ' ') )
{
  bool isNum = true;
  for(int i = 0; i < rawInput.length() && isNum; ++i)
  {
    isNum = isdigit( rawInput[i]);
  }

  if(isNum)
  {
    num = atoi( rawInput.c_str() );
    ...//do your stuff
  }
  else
    cout << rawInput << " is not a number!" << endl;
}

The boolean (true/false or 1/0 respectively) is used as a flag for the for-loop, which steps through each character in the string and checks to see if it is a 0-9 digit. If any character in the string is not a digit, the loop will break during it's next execution when it gets to the condition "&& isNum" (assuming you've covered loops already). Then after the loop, isNum is used to determine whether to do your stuff, or to print the error message.

How malloc() and free() works depends on the runtime library used. Generally, malloc() allocates a heap (a block of memory) from the operating system. Each request to malloc() then allocates a small chunk of this memory be returning a pointer to the caller. The memory allocation routines will have to store some extra information about the block of memory allocated to be able to keep track of used and free memory on the heap. This information is often stored in a few bytes just before the pointer returned by malloc() and it can be a linked list of memory blocks.

By writing past the block of memory allocated by malloc() you will most likely destroy some of the book-keeping information of the next block which may be the remaining unused block of memory.

One place where you program may also crash is when copying too many characters into the buffer. If the extra characters are located outside the heap you may get an access violation as you are trying to write to non-existing memory.

Correct me if i'm wrong, but json is just text seperated by ":", so just use

String line = ""; //stores the text to parse.

StringTokenizer st = new StringTokenizer(line, ":");
String input1 = st.nextToken();

keep using st.nextToken() until you're out of data. Make sure to use "st.hasNextToken()" so you don't get a null exception.

One way, making the preprocessor do the work. It also ensures your enums and strings are in sync.

#define FOREACH_FRUIT(FRUIT) \
        FRUIT(apple)   \
        FRUIT(orange)  \
        FRUIT(grape)   \
        FRUIT(banana)  \

#define GENERATE_ENUM(ENUM) ENUM,
#define GENERATE_STRING(STRING) #STRING,

enum FRUIT_ENUM {
    FOREACH_FRUIT(GENERATE_ENUM)
};

static const char *FRUIT_STRING[] = {
    FOREACH_FRUIT(GENERATE_STRING)
};

After the preprocessor gets done, you'll have:

enum FRUIT_ENUM {
    apple, orange, grape, banana,
};

static const char *FRUIT_STRING[] = {
    "apple", "orange", "grape", "banana",
};

Then you could do something like:

printf("enum apple as a string: %s\n",FRUIT_STRING[apple]);

If the use case is literally just printing the enum name, add the following macros:

#define str(x) #x
#define xstr(x) str(x)

Then do:

printf("enum apple as a string: %s\n", xstr(apple));

In this case, it may seem like the two-level macro is superfluous, however, due to how stringification works in C, it is necessary in some cases. For example, let's say we want to use a #define with an enum:

#define foo apple

int main() {
    printf("%s\n", str(foo));
    printf("%s\n", xstr(foo));
}

The output would be:

foo
apple

This is because str will stringify the input foo rather than expand it to be apple. By using xstr the macro expansion is done first, then that result is stringified.

See Stringification for more information.

Here is the correct code for Swift 3, with comments for instructional purposes:

override func viewDidLoad()
{
    super.viewDidLoad()

    // CGRectMake has been deprecated - and should be let, not var
    let label = UILabel(frame: CGRect(x: 0, y: 0, width: 200, height: 21))

    // you will probably want to set the font (remember to use Dynamic Type!)
    label.font = UIFont.preferredFont(forTextStyle: .footnote)

    // and set the text color too - remember good contrast
    label.textColor = .black

    // may not be necessary (e.g., if the width & height match the superview)
    // if you do need to center, CGPointMake has been deprecated, so use this
    label.center = CGPoint(x: 160, y: 284)

    // this changed in Swift 3 (much better, no?)
    label.textAlignment = .center

    label.text = "I am a test label"

    self.view.addSubview(label)
}

xcopy "%userprofile%\Desktop\?????????" "D:\Backup\" /s/h/e/k/f/c

should work, assuming that your language setting allows Cyrillic (or you use Unicode fonts in the console).

For reference about the arguments: http://ss64.com/nt/xcopy.html

The error seems not to be one of a character field, but more of a numeric one. (If it were a string problem like WW mentioned, you'd get a 'value too big' or something similar.) Probably you are using more digits than are allowed, e.g. 1,000000001 in a column defined as number (10,2).

Look at the source code as WW mentioned to figure out what column may be causing the problem. Then check the data if possible that is being used there.

For windows: Best is to use pre-compiled package available from this site: http://www.lfd.uci.edu/%7Egohlke/pythonlibs/#scipy

It says on the PHP site that multiple queries are NOT permitted (EDIT: This is only true for the mysql extension. mysqli and PDO allow multiple queries) . So you can't do it in PHP, BUT, why can't you just execute that query in another mysql_query call, (like Jon's example)? It should still give you the correct result if you use the same connection. Also, mysql_num_rows may help also.

Considering

$string="We have www/audio path where the audio files are stored";  //Considering the string like this

Either you can use

strstr($string, 'www/audio');

Or

$expStr=explode("www/audio",$string);
$resultString="www/audio".$expStr[1];

If you know you're always going to use bash, it's much easier to always use the double bracket conditional compound command [[ ... ]], instead of the Posix-compatible single bracket version [ ... ]. Inside a [[ ... ]] compound, word-splitting and pathname expansion are not applied to words, so you can rely on

if [[ $aug1 == "and" ]];

to compare the value of $aug1 with the string and.

If you use [ ... ], you always need to remember to double quote variables like this:

if [ "$aug1" = "and" ];

If you don't quote the variable expansion and the variable is undefined or empty, it vanishes from the scene of the crime, leaving only

if [ = "and" ]; 

which is not a valid syntax. (It would also fail with a different error message if $aug1 included white space or shell metacharacters.)

The modern [[ operator has lots of other nice features, including regular expression matching.

Take a look at http://vpython.org/contents/docs/visual/VisualIntro.html.

It provides a vector class which has a method A.rotate(theta,B). It also provides a helper function rotate(A,theta,B) if you don't want to call the method on A.

Argh! From the FAQ:

How do I see a list of all of the ansible_ variables? Ansible by default gathers “facts” about the machines under management, and these facts can be accessed in Playbooks and in templates. To see a list of all of the facts that are available about a machine, you can run the “setup” module as an ad-hoc action:

ansible -m setup hostname

This will print out a dictionary of all of the facts that are available for that particular host.

Here is the output for my vagrant virtual machine called scdev:

scdev | success >> {
    "ansible_facts": {

Use -d (full list of file tests)

if (-d "cgi-bin") {
    # directory called cgi-bin exists
}
elsif (-e "cgi-bin") {
    # cgi-bin exists but is not a directory
}
else {
    # nothing called cgi-bin exists
}

As a note, -e doesn't distinguish between files and directories. To check if something exists and is a plain file, use -f.

Just use z-index CSS property as described in the highest liked answer and the nav bar will stick to the top.

Example:

<div class="navigation">
 <nav>
   <ul>
    <li>Home</li>
    <li>Contact</li>
   </ul>
 </nav>

.navigation {
   /* fixed keyword is fine too */
   position: sticky;
   top: 0;
   z-index: 100;
   /* z-index works pretty much like a layer:
   the higher the z-index value, the greater
   it will allow the navigation tag to stay on top
   of other tags */
}

Following these reccomended directions seemed to work:

Hint: Open the SDK manager by running: /path/to/android/tools/android

You will require: 1. "SDK Platform" for android-23 2. "Android SDK Platform-tools (latest) 3. "Android SDK Build-tools" (latest)

There is a package called eclipse-cdt in the Ubuntu 12.10 repositories, this is what you want. If you haven't got g++ already, you need to install that as well, so all you need is:

sudo apt-get install eclipse eclipse-cdt g++

Whether you messed up your system with your previous installation attempts depends heavily on how you did it. If you did it the safe way for trying out new packages not from repositories (i.e., only installed in your home folder, no sudos blindly copied from installation manuals...) you're definitely fine. Otherwise, you may well have thousands of stray files all over your file system now. In that case, run all uninstall scripts you can find for the things you installed, then install using apt-get and hope for the best.

suppose you have a nested object, like

var obj = {"parent": {"child": {....}}}

If you passed the reference of the complete object, like

[wholeObj] = "obj"

In that case, you can't detect the changes in the child objects, so to overcome this problem you can also pass the reference of the child object through another property, like

[wholeObj] = "obj" [childObj] = "obj.parent.child"

So you can also detect the changes from the child objects too.

ngOnChanges(changes: SimpleChanges) { 
    if (changes.childObj) {// your logic here}
}

NamingException's answer worked for me. Except I used

var date = $("#date").dtpicker({ dateFormat: 'dd,MM,yyyy' }).val()

datepicker didn't work but dtpicker did.

Add to the div style:

width: fit-content;

Well, after I did all those things I still got the errors so I closed Xcode and opened it up again and then it worked.

I suggest to use the name of the computer, e.g.http://mymac:1337/. Works for me perfect without any configuration required and I don't have to care about changing IP addresses due DHCP.

The accepted answer didn't work in my situation, not sure why. I switched from JRE1.7 to JRE1.8 and that resolved the issue automatically. JRE1.8 uses TLS1.2 by default

A DTU is a unit of measure for the performance of a service tier and is a summary of several database characteristics. Each service tier has a certain number of DTUs assigned to it as an easy way to compare the performance level of one tier versus another.

Database Throughput Unit (DTU): DTUs provide a way to describe the relative capacity of a performance level of Basic, Standard, and Premium databases. DTUs are based on a blended measure of CPU, memory, reads, and writes. As DTUs increase, the power offered by the performance level increases. For example, a performance level with 5 DTUs has five times more power than a performance level with 1 DTU. A maximum DTU quota applies to each server.

The DTU Quota applies to the server, not the individual databases and each server has a maximum of 1600 DTUs. The DTU% is the percentage of units your particular database is using and it seems that this number can go over 100% of the DTU rating of the service tier (I assume to the limit of the server). This percentage number is designed to help you choose the appropriate service tier.

From down toward the bottom of this announcement:

For example, if your DTU consumption shows a value of 80%, it indicates it is consuming DTU at the rate of 80% of the limit an S2 database would have. If you see values greater than 100% in this view it means that you need a performance tier larger than S2.

As an example, let’s say you see a percentage value of 300%. This tells you that you are using three times more resources than would be available in an S2. To determine a reasonable starting size, compare the DTUs available in an S2 (50 DTUs) with the next higher sizes (P1 = 100 DTUs, or 200% of S2, P2 = 200 DTUs or 400% of S2). Because you are at 300% of S2 you would want to start with a P2 and re-test.

for (int i = 0; i < clbIncludes.Items.Count; i++)
  if (clbIncludes.GetItemChecked(i))
    // Do selected stuff
  else
    // Do unselected stuff

If the the check is in indeterminate state, this will still return true. You may want to replace

if (clbIncludes.GetItemChecked(i))

with

if (clbIncludes.GetItemCheckState(i) == CheckState.Checked)

if you want to only include actually checked items.

If you use Unicode Character Set, but the entry wasn't set, you can specify /ENTRY:"wWinMainCRTStartup"

I have been searching for a solution for this and found it today. Here is how you can do it.

default clean command did not work for me giving following error:

$ slack-cleaner --token=<TOKEN> --message --channel <CHANNEL>

Running slack-cleaner v0.2.4
Channel, direct message or private group not found

but following worked without any issue to clean the bot messages

slack-cleaner --token <TOKEN> --message --group <CHANNEL> --bot --perform --rate 1 

or

slack-cleaner --token <TOKEN> --message --group <CHANNEL> --user "*" --perform --rate 1 

to clean all the messages.

I use rate-limit of 1 second to avoid HTTP 429 Too Many Requests error because of slack api rate limit. In both cases, channel name was supplied without # sign

I could do this on Linux.

$ pip3 install --user 'requests[socks]'
$ https_proxy=socks5://<hostname or ip>:<port> python3 -c \

By using cursor you can easily iterate through records individually and print records separately or as a single message including all the records.

DECLARE @CustomerID as INT;
declare @msg varchar(max)
DECLARE @BusinessCursor as CURSOR;

SET @BusinessCursor = CURSOR FOR
SELECT CustomerID FROM Customer WHERE CustomerID IN ('3908745','3911122','3911128','3911421')

OPEN @BusinessCursor;
    FETCH NEXT FROM @BusinessCursor INTO @CustomerID;
    WHILE @@FETCH_STATUS = 0
        BEGIN
            SET @msg = '{
              "CustomerID": "'+CONVERT(varchar(10), @CustomerID)+'",
              "Customer": {
                "LastName": "LastName-'+CONVERT(varchar(10), @CustomerID) +'",
                "FirstName": "FirstName-'+CONVERT(varchar(10), @CustomerID)+'",    
              }
            }|'
        print @msg
    FETCH NEXT FROM @BusinessCursor INTO @CustomerID;
END

if you're using SQL Server,

dateadd(DAY,0, datediff(day,0, created)) will return the day created

for example, if the sale created on '2009-11-02 06:12:55.000', dateadd(DAY,0, datediff(day,0, created)) return '2009-11-02 00:00:00.000'

select sum(amount) as total, dateadd(DAY,0, datediff(day,0, created)) as created
from sales
group by dateadd(DAY,0, datediff(day,0, created))

.forEach already has this ability:

const someArray = [9, 2, 5];
someArray.forEach((value, index) => {
    console.log(index); // 0, 1, 2
    console.log(value); // 9, 2, 5
});

But if you want the abilities of for...of, then you can map the array to the index and value:

for (const { index, value } of someArray.map((value, index) => ({ index, value }))) {
    console.log(index); // 0, 1, 2
    console.log(value); // 9, 2, 5
}

That's a little long, so it may help to put it in a reusable function:

function toEntries<T>(a: T[]) {
    return a.map((value, index) => [index, value] as const);
}

for (const [index, value] of toEntries(someArray)) {
    // ..etc..
}

Iterable Version

This will work when targeting ES3 or ES5 if you compile with the --downlevelIteration compiler option.

function* toEntries<T>(values: T[] | IterableIterator<T>) {
    let index = 0;
    for (const value of values) {
        yield [index, value] as const;
        index++;
    }
}

Array.prototype.entries() - ES6+

If you are able to target ES6+ environments then you can use the .entries() method as outlined in Arnavion's answer.

I could be wrong, but I believe since you are inheriting from foo, you have to call a base constructor. Since you explicitly defined the foo constructor to require (int, int) now you need to pass that up the chain.

public bar(int a, int b) : base(a, b)
{
     c = a * b;
}

This will initialize foo's variables first and then you can use them in bar. Also, to avoid confusion I would recommend not naming parameters the exact same as the instance variables. Try p_a or something instead, so you won't accidentally be handling the wrong variable.

You can use the pluck method:

Word_relation::where('word_one', $word_id)->pluck('word_two')->toArray();

For more info on what methods are available for using with collection, you can you can check out the Laravel Documentation.

Or do it this way to use ALL jQuery. The each can loop through any data be it DOM elements or an array/object.

var data = ['one', 'two', 'three', 'four', 'five', 'six', 'seven', 'eight'];
var numCols = 1;           


$.each(data, function(i) {
  if(!(i%numCols)) tRow = $('<tr>');

  tCell = $('<td>').html(data[i]);

  $('table').append(tRow.append(tCell));
});

A simpler solution would be to do an inorder traversal and keep track of the element currently to be printed with a counter k. When we reach k, print the element. The runtime is O(n). Remember the function return type can not be void, it has to return its updated value of k after each recursive call. A better solution to this would be an augmented BST with a sorted position value at each node.

public static int kthSmallest (Node pivot, int k){
    if(pivot == null )
        return k;   
    k = kthSmallest(pivot.left, k);
    k--;
    if(k == 0){
        System.out.println(pivot.value);
    }
    k = kthSmallest(pivot.right, k);
    return k;
}

        //Call alert from shared class
        SharedClass.sharedInstance.alert(view: self, title: "", message: msg)
    } else {
        //Call spinner from shared class

        task.resume()

    }

}

If you have interest to use this function in SharedClass

//My shared class
import UIKit
class SharedClass: NSObject {

static let sharedInstance = SharedClass()

func postRequestFunction(apiName: String , parameters: String, onCompletion: @escaping (_ success: Bool, _ error: Error?, _ result: [String: Any]?)->()) {

    var URL =  "your URL here/index.php/***?"

    URL = URL.replacingOccurrences(of: "***", with: apiName)

    var request = URLRequest(url: URL(string: URL)!)
    request.setValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")
    request.httpMethod = "POST"
    print("shared URL : \(request)")
    request.httpBody = parameters.data(using: .utf8)

    var returnRes:[String:Any] = [:]
    let task = URLSession.shared.dataTask(with: request) { data, response, error in

        if let error = error {
            onCompletion(false, error, nil)
        } else {
            guard let data = data else {
                onCompletion(false, error, nil)
                return
            }

            if let httpStatus = response as? HTTPURLResponse, httpStatus.statusCode == 200 {
                do {
                   returnRes = try JSONSerialization.jsonObject(with: data, options: []) as! [String : Any]
                    onCompletion(true, nil, returnRes)

                } catch let error as NSError {
                   onCompletion(false, error, nil)
                }
            } else {
                onCompletion(false, error, nil)
            }
        }
    }
    task.resume()
}


private override init() {

}

And finally call this function like this....

SharedClass.sharedInstance.postRequestFunction(apiName: "Your API name", parameters: parameters) { (success, error, result) in
    print(result!)
    if success {
        //Your code here
    } else {
        print(error?.localizedDescription ?? "")
    }
}

To prevent duplication in memory, resharper is suggesting this:

List<string> myList = new List<string>();
IEnumerable<string> myEnumerable = myList;
List<string> listAgain = myList as List<string>() ?? myEnumerable.ToList();

.ToList() returns a new immutable list. So changes to listAgain does not effect myList in @Tamas Czinege answer. This is correct in most instances for least two reasons: This helps prevent changes in one area effecting the other area (loose coupling), and it is very readable, since we shouldn't be designing code with compiler concerns.

But there are certain instances, like being in a tight loop or working on an embedded or low memory system, where compiler considerations should be taken into consideration.

Two other alternatives:

3. a combination of NULLIF and NVL2. You can only use this if emp_id is NOT NULL, which it is in your case:

   select nvl2(nullif(emp_id,1),'False','True') from employee;
   

4. simple CASE expression (Mt. Schneiders used a so-called searched CASE expression)

   select case emp_id when 1 then 'True' else 'False' end from employee;
   

Here is the code of removing duplicates values from NSMutable Array..it will work for you. myArray is your Mutable Array that you want to remove duplicates values..

for(int j = 0; j < [myMutableArray count]; j++){
    for( k = j+1;k < [myMutableArray count];k++){
    NSString *str1 = [myMutableArray objectAtIndex:j];
    NSString *str2 = [myMutableArray objectAtIndex:k];
    if([str1 isEqualToString:str2])
        [myMutableArray removeObjectAtIndex:k];
    }
 } // Now print your array and will see there is no repeated value

OSX users can follow by Nicolay77 or mikkom that uses the mdbtools utility. You can install it via Homebrew. Just have your homebrew installed and then go

$ homebrew install mdbtools

Then create one of the scripts described by the guys and use it. I've used mikkom's one, converted all my mdb files into sql.

$ ./to_mysql.sh myfile.mdb > myfile.sql

(which btw contains more than 1 table)

I combined two of the previous answers (jsfiddle).

input {
    /* round the corners */
    border-radius: 4px;
    -moz-border-radius: 4px;
    -webkit-border-radius: 4px;    
}

input:focus { 
    outline:none;
    border: 1px solid #4195fc; 
    /* create a BIG glow */
    box-shadow: 0px 0px 14px #4195fc; 
    -moz-box-shadow: 0px 0px 14px #4195fc;
    -webkit-box-shadow: 0px 0px 14px #4195fc;  
}?

Without using set

data=[1, 2, 3, 1, 2, 5, 6, 7, 8]
uni_data=[]
for dat in data:
    if dat not in uni_data:
        uni_data.append(dat)

print(uni_data) 

Judging from other answers, no one except @rob-kennedy talked about the call_args_list.

It's a powerful tool for that you can implement the exact contrary of MagicMock.assert_called_with()

call_args_list is a list of call objects. Each call object represents a call made on a mocked callable.

>>> from unittest.mock import MagicMock
>>> m = MagicMock()
>>> m.call_args_list
[]
>>> m(42)
<MagicMock name='mock()' id='139675158423872'>
>>> m.call_args_list
[call(42)]
>>> m(42, 30)
<MagicMock name='mock()' id='139675158423872'>
>>> m.call_args_list
[call(42), call(42, 30)]

Consuming a call object is easy, since you can compare it with a tuple of length 2 where the first component is a tuple containing all the positional arguments of the related call, while the second component is a dictionary of the keyword arguments.

>>> ((42,),) in m.call_args_list
True
>>> m(42, foo='bar')
<MagicMock name='mock()' id='139675158423872'>
>>> ((42,), {'foo': 'bar'}) in m.call_args_list
True
>>> m(foo='bar')
<MagicMock name='mock()' id='139675158423872'>
>>> ((), {'foo': 'bar'}) in m.call_args_list
True

So, a way to address the specific problem of the OP is

def test_something():
    with patch('something') as my_var:
        assert ((some, args),) not in my_var.call_args_list

Note that this way, instead of just checking if a mocked callable has been called, via MagicMock.called, you can now check if it has been called with a specific set of arguments.

That's useful. Say you want to test a function that takes a list and call another function, compute(), for each of the value of the list only if they satisfy a specific condition.

You can now mock compute, and test if it has been called on some value but not on others.

use app.render in scenarios where you need to render a view but not send it to a client via http. html emails springs to mind.

Option 2 will work. You could also use a Set<Character> or

char[] myCharSet = new char[] {'A', 'B', 'C', ...};
Arrays.sort(myCharSet);
if (Arrays.binarySearch(myCharSet, symbol) >= 0) { ... }

Sometimes you need to grep the process by name - in that case:

ps aux | grep simple-scan

Example output:

simple-scan  1090  0.0  0.1   4248  1432 ?        S    Jun11   0:00

I made it calculate days in month from datetimepicker selected month and year , and I but the code in datetimepicker1 textchanged to return the result in a textbox with this code

private void DateTimePicker1_ValueChanged(object sender, EventArgs e)
{
    int s = System.DateTime.DaysInMonth(DateTimePicker1.Value.Date.Year, DateTimePicker1.Value.Date.Month);

    TextBox1.Text = s.ToString();
} 

Night's answer is correct

 html, body {margin:0;padding:0;height:100%;}

Also check that your div or element is NOT inside another one (with height less than 100%) Hope this helps someone else.

So many ways to do it.

From Workbench: File > Run SQL Script -- then follow prompts

From Windows Command Line:
   Option 1: mysql -u usr -p
             mysql> source file_path.sql
   Option 2: mysql -u usr -p '-e source file_path.sql'
   Option 3: mysql -u usr -p < file_path.sql
   Option 4: put multiple 'source' statements inside of file_path.sql (I do this to drop and recreate schemas/databases which requires multiple files to be run)
             mysql -u usr -p < file_path.sql

If you get errors from the command line, make sure you have previously run

cd {!!>>mysqld.exe home directory here<<!!}
mysqld.exe --initialize 

This must be run from within the mysqld.exe directory, hence the CD.

Hope this is helpful and not just redundant.

This is Linq

var mergedList = list1.Union(list2).ToList();

This is Normaly (AddRange)

var mergedList=new List<Person>();
mergeList.AddRange(list1);
mergeList.AddRange(list2);

This is Normaly (Foreach)

var mergedList=new List<Person>();

foreach(var item in list1)
{
    mergedList.Add(item);
}
foreach(var item in list2)
{
     mergedList.Add(item);
}

This is Normaly (Foreach-Dublice)

var mergedList=new List<Person>();

foreach(var item in list1)
{
    mergedList.Add(item);
}
foreach(var item in list2)
{
   if(!mergedList.Contains(item))
   {
     mergedList.Add(item);
   }
}

It's often the good idea to rely on standard library provided solution:

private static void stackOverflow15554296()
    throws
        NoSuchAlgorithmException, NoSuchPaddingException,        
        InvalidKeyException, IllegalBlockSizeException,
        BadPaddingException
{

    // prepare key
    KeyGenerator keygen = KeyGenerator.getInstance("AES");
    SecretKey aesKey = keygen.generateKey();
    String aesKeyForFutureUse = Base64.getEncoder().encodeToString(
            aesKey.getEncoded()
    );

    // cipher engine
    Cipher aesCipher = Cipher.getInstance("AES/ECB/PKCS5Padding");

    // cipher input
    aesCipher.init(Cipher.ENCRYPT_MODE, aesKey);
    byte[] clearTextBuff = "Text to encode".getBytes();
    byte[] cipherTextBuff = aesCipher.doFinal(clearTextBuff);

    // recreate key
    byte[] aesKeyBuff = Base64.getDecoder().decode(aesKeyForFutureUse);
    SecretKey aesDecryptKey = new SecretKeySpec(aesKeyBuff, "AES");

    // decipher input
    aesCipher.init(Cipher.DECRYPT_MODE, aesDecryptKey);
    byte[] decipheredBuff = aesCipher.doFinal(cipherTextBuff);
    System.out.println(new String(decipheredBuff));
}

This prints "Text to encode".

Solution is based on Java Cryptography Architecture Reference Guide and https://stackoverflow.com/a/20591539/146745 answer.

From C++ Templates The Complete Guide:

Member function templates cannot be declared virtual. This constraint is imposed because the usual implementation of the virtual function call mechanism uses a fixed-size table with one entry per virtual function. However, the number of instantiations of a member function template is not fixed until the entire program has been translated. Hence, supporting virtual member function templates would require support for a whole new kind of mechanism in C++ compilers and linkers. In contrast, the ordinary members of class templates can be virtual because their number is fixed when a class is instantiated

This should work, but there is a little trick. After you enter the formula, you need to hold down Ctrl+Shift while you press Enter. When you do, you'll see that the formula bar has curly-braces around your formula. This is called an array formula.

For example, if the Months are in cells A2:A100 and the amounts are in cells B2:B100, your formula would look like {=SUM(If(A2:A100="January",B2:B100))}. You don't actually type the curly-braces though.

You could also do something like =SUM((A2:A100="January")*B2:B100). You'd still need to use the trick to get it to work correctly.

If you want to stay close to .NET check out Enterprise Library Logging Application Block. Look here. Or for a quickstart tutorial check this. I have used the Validation application Block from the Enterprise Library and it really suits my needs and is very easy to "inherit" (install it and refrence it!) in your project.

d and i conversion specifiers behave the same with fprintf but behave differently for fscanf.

As some other wrote in their answer, the idiomatic way to print an int is using d conversion specifier.

Regarding i specifier and fprintf, C99 Rationale says that:

The %i conversion specifier was added in C89 for programmer convenience to provide symmetry with fscanf’s %i conversion specifier, even though it has exactly the same meaning as the %d conversion specifier when used with fprintf.

You can try this

$('#startdate').val()

or

$('#startdate').data('date')

nltk.download() will not solve this issue. I tried the below and it worked for me:

in the '...AppData\Roaming\nltk_data\tokenizers' folder, extract downloaded punkt.zip folder at the same location.

The Apache Geronimo project provides a Servlet 3.0 API dependency on the Maven Central repo:

<dependency>
    <groupId>org.apache.geronimo.specs</groupId>
    <artifactId>geronimo-servlet_3.0_spec</artifactId>
    <version>1.0</version>
</dependency>

HTML is in its basic form just XML. You could Parse your text in an XmlDocument object, and on the root element call InnerText to extract the text. This will strip all HTML tages in any form and also deal with special characters like <   all in one go.

First download the exe file of the IEDriverServer (64 bit and 32 bit). Don't need to install, only download this file with your browser( 64 or 32 bit) and simply give the path of the exe file in the given code.

http://www.seleniumhq.org/download/

use this code

package myProject;

import org.openqa.selenium.ie.InternetExplorerDriver;

public class Browserlaunch {

    public static void main(String[] args) {

        System.setProperty("webdriver.ie.driver", "C:/Drivers/IEDriverServer.exe");
        InternetExplorerDriver IEDriver=new InternetExplorerDriver();
        IEDriver.get("http://localhost:8888");
    }
}

I would use the SET command from the command prompt to export all the variables, rather than just PATH as recommended above.

C:\> SET >> allvariables.txt

To import the variablies, one can use a simple loop:

C:\> for /F %A in (allvariables.txt) do SET %A

Yes there is using the following code will allow you to apply a blurring effect to the specified image and also it will allow you to choose the amount of blurring.

img {
  -webkit-filter: blur(10px);
    filter: blur(10px);
}

In my view the perfect answer you must required is

var reader = new FileReader();

//Read the contents of Image File.
reader.readAsDataURL(fileUpload.files[0]);
reader.onload = function (e) {

  //Initiate the JavaScript Image object.
  var image = new Image();

  //Set the Base64 string return from FileReader as source.
  image.src = e.target.result;

  //Validate the File Height and Width.
  image.onload = function () {
    var height = this.height;
    var width = this.width;
    if (height > 100 || width > 100) {
      alert("Height and Width must not exceed 100px.");
      return false;
    }
    alert("Uploaded image has valid Height and Width.");
    return true;
  };
};

• real: The actual time spent in running the process from start to finish, as if it was measured by a human with a stopwatch

• user: The cumulative time spent by all the CPUs during the computation

• sys: The cumulative time spent by all the CPUs during system-related tasks such as memory allocation.

Notice that sometimes user + sys might be greater than real, as multiple processors may work in parallel.

Here how to build a CLASSPATH by scanning a given directory.

setlocal ENABLEDELAYEDEXPANSION
if defined CLASSPATH (set CLASSPATH=%CLASSPATH%;.) else (set CLASSPATH=.)
FOR /R .\lib %%G IN (*.jar) DO set CLASSPATH=!CLASSPATH!;%%G
Echo The Classpath definition is %CLASSPATH%

works in XP (or better). With W2K, you need to use a couple of BAT files to achieve the same result (see Include all jars in the classpath definition ).

It's not needed for 1.6 since you can specify a wildcard directly in CLASSPATH (ex. -cp ".\lib*").

It's the "Import existing project into workspace" option under Import->General.

your_list = [None]*size_required

To reference the contents of the single array containing one or more objects i.e. everything in the brackets of something like this {messages: [{"a":1,"b":2}] } ,just add [0] to the query to get the first array element

e.g. messages[0] will reference the object {"a":1,"b":2} as opposed to just messages which would reference the entire array [{"a":1,"b":2}]

from there you can work with the result as typical object and use Object.keys for example to get "a" and "b".

In Jenkins 2.138.3 there are two different types of pipelines.

Declarative and Scripted pipelines.

"Declarative pipelines is a new extension of the pipeline DSL (it is basically a pipeline script with only one step, a pipeline step with arguments (called directives), these directives should follow a specific syntax. The point of this new format is that it is more strict and therefore should be easier for those new to pipelines, allow for graphical editing and much more. scripted pipelines is the fallback for advanced requirements."

jenkins pipeline: agent vs node?

Here is an example of using environment and global variables in a Declarative Pipeline. From what I can tell enviroment are static after they are set.

def  browser = 'Unknown'

pipeline {
    agent any
    environment {
    //Use Pipeline Utility Steps plugin to read information from pom.xml into env variables
    IMAGE = readMavenPom().getArtifactId()
    VERSION = readMavenPom().getVersion()


    }
    stages {
        stage('Example') {
            steps {
                script {
                    browser = sh(returnStdout: true, script: 'echo Chrome')
                }
            }
        }
        stage('SNAPSHOT') {
                when {
                    expression { 
                        return !env.JOB_NAME.equals("PROD") && !env.VERSION.contains("RELEASE")
                    }
                }
                steps {
                    echo "SNAPSHOT"
                    echo "${browser}"
                }
            }
            stage('RELEASE') {
                when {
                    expression { 
                        return !env.JOB_NAME.equals("TEST") && !env.VERSION.contains("RELEASE")
                    }
                }
                steps {
                    echo "RELEASE"
                    echo "${browser}"
                }
            }
    }//end of stages 
}//end of pipeline

Usually you already know the extension, so you might wish to use:

basename filename .extension

for example:

basename /path/to/dir/filename.txt .txt

and we get

filename

I've had to do this a few times to-date. Note that this only works on 1 file at a time.

1. Get a list of all commits that modified a file. The one at the bottom will the the first commit:

   git log --pretty=oneline --branches -- pathToFile

2. To remove the file from history use the first commit sha1 and the path to file from the previous command, and fill them into this command:

   git filter-branch --index-filter 'git rm --cached --ignore-unmatch <path-to-file>' -- <sha1-where-the-file-was-first-added>..

There is a Ruby gem that interfaces your ssh configuration file which is called sshez.

All you have to do is sshez <alias> [email protected] -p <port-number>, and then you can connect using ssh <alias>. It is also useful since you can list your aliases using sshez list and can easily remove them using sshez remove alias.

I updated the plugin with the nightly builds: http://www.eclipse.org/egit/download/

With an update, it worked for me. (Eclipse Helios, Mac OS X)

UPDATE : The accepted answer provides the solution, but .on() is the method that should be use from now on.

"As of jQuery 3.0, .bind() has been deprecated. It was superseded by the .on() method for attaching event handlers to a document since jQuery 1.7, so its use was already discouraged."

For those who are having trouble with fatal error: ESP8266WiFi.h: No such file or directory, you can install the package manually.

1. Download the Arduino ESP8266 core from here https://github.com/esp8266/Arduino
2. Go into library from the downloaded core and grab ESP8266WiFi.
3. Drag that into your local Arduino/library folder. This can be found by going into preferences and looking at your Sketchbook location

You may still need to have the http://arduino.esp8266.com/stable/package_esp8266com_index.json package installed beforehand, however.

Edit: That wasn't the full issue, you need to make sure you have the correct ESP8266 Board selected before compiling.

Hope this helps others.

I'm using this wrapper, which comfortably turns any function for running in a Thread - taking care of its return value or exception. It doesn't add Queue overhead.

def threading_func(f):
    """Decorator for running a function in a thread and handling its return
    value or exception"""
    def start(*args, **kw):
        def run():
            try:
                th.ret = f(*args, **kw)
            except:
                th.exc = sys.exc_info()
        def get(timeout=None):
            th.join(timeout)
            if th.exc:
                raise th.exc[0], th.exc[1], th.exc[2] # py2
                ##raise th.exc[1] #py3                
            return th.ret
        th = threading.Thread(None, run)
        th.exc = None
        th.get = get
        th.start()
        return th
    return start

Usage Examples

def f(x):
    return 2.5 * x
th = threading_func(f)(4)
print("still running?:", th.is_alive())
print("result:", th.get(timeout=1.0))

@threading_func
def th_mul(a, b):
    return a * b
th = th_mul("text", 2.5)

try:
    print(th.get())
except TypeError:
    print("exception thrown ok.")

Notes on threading module

Comfortable return value & exception handling of a threaded function is a frequent "Pythonic" need and should indeed already be offered by the threading module - possibly directly in the standard Thread class. ThreadPool has way too much overhead for simple tasks - 3 managing threads, lots of bureaucracy. Unfortunately Thread's layout was copied from Java originally - which you see e.g. from the still useless 1st (!) constructor parameter group.

Sorry I am very late to the party.

Let me try to explain the difference using mvn dependency:tree command

Consider the below example

Parent POM - My Project

<modules>
    <module>app</module>
    <module>data</module>
</modules>

<dependencies>
    <dependency>
        <groupId>com.google.guava</groupId>

    <dependencies>
        <dependency>
            <groupId>org.apache.commons</groupId>
            <artifactId>commons-lang3</artifactId>
            <version>3.9</version>
        </dependency>
    </dependencies>
</dependencyManagement>

Child POM - data module

<dependencies>
    <dependency>
        <groupId>org.apache.commons</groupId>
        <artifactId>commons-lang3</artifactId>
    </dependency>
</dependencies>

Child POM - app module (has no extra dependency, so leaving dependencies empty)

 <dependencies>
</dependencies>

On running mvn dependency:tree command, we get following result

There are various Inline elements that can help you, for the simplest formatting options you can use Bold, Italic and Underline:

<TextBlock>
    Sample text with <Bold>bold</Bold>, <Italic>italic</Italic> and <Underline>underlined</Underline> words.
</TextBlock>

I think it is worth noting, that those elements are in fact just shorthands for Span elements with various properties set (i.e.: for Bold, the FontWeight property is set to FontWeights.Bold).

This brings us to our next option: the aforementioned Span element.

You can achieve the same effects with this element as above, but you are granted even more possibilities; you can set (among others) the Foreground or the Background properties:

<TextBlock>
    Sample text with <Span FontWeight="Bold">bold</Span>, <Span FontStyle="Italic">italic</Span> and <Span TextDecorations="Underline">underlined</Span> words. <Span Foreground="Blue">Coloring</Span> <Span Foreground="Red">is</Span> <Span Background="Cyan">also</Span> <Span Foreground="Silver">possible</Span>.
</TextBlock>

The Span element may also contain other elements like this:

<TextBlock>
    <Span FontStyle="Italic">Italic <Span Background="Yellow">text</Span> with some <Span Foreground="Blue">coloring</Span>.</Span>
</TextBlock>

There is another element, which is quite similar to Span, it is called Run. The Run cannot contain other inline elements while the Span can, but you can easily bind a variable to the Run's Text property:

<TextBlock>
    Username: <Run FontWeight="Bold" Text="{Binding UserName}"/>
</TextBlock>

Also, you can do the whole formatting from code-behind if you prefer:

TextBlock tb = new TextBlock();
tb.Inlines.Add("Sample text with ");
tb.Inlines.Add(new Run("bold") { FontWeight = FontWeights.Bold });
tb.Inlines.Add(", ");
tb.Inlines.Add(new Run("italic ") { FontStyle = FontStyles.Italic });
tb.Inlines.Add("and ");
tb.Inlines.Add(new Run("underlined") { TextDecorations = TextDecorations.Underline });
tb.Inlines.Add("words.");

=> [5, 6] 

If you want to remove n starting elements you can use x.shift(n)

The options property contains all the <options> - from there you can look at .text

document.getElementById('test').options[0].text == 'Text One'

Here is an example of what I would do. I hope it's what you're looking for.

char_array = c("foo_bar","bar_foo","apple","beer")
a = data.frame("data"=char_array,"data2"=1:4)
a$data = substr(a$data,1,nchar(a$data)-3)

a should now contain:

  data data2
1 foo_ 1
2 bar_ 2
3   ap 3
4    b 4

ORDER BY column OFFSET 0 ROWS

Surprisingly makes it work, what a strange feature.

A bigger example with a CTE as a way to temporarily "store" a long query to re-order it later:

;WITH cte AS (
    SELECT .....long select statement here....
)

SELECT * FROM 
(
    SELECT * FROM 
    ( -- necessary to nest selects for union to work with where & order clauses
        SELECT * FROM cte WHERE cte.MainCol= 1 ORDER BY cte.ColX asc OFFSET 0 ROWS 
    ) first
    UNION ALL
    SELECT * FROM 
    (  
        SELECT * FROM cte WHERE cte.MainCol = 0 ORDER BY cte.ColY desc OFFSET 0 ROWS 
    ) last
) as unionized
ORDER BY unionized.MainCol desc -- all rows ordered by this one
OFFSET @pPageSize * @pPageOffset ROWS -- params from stored procedure for pagination, not relevant to example
FETCH FIRST @pPageSize ROWS ONLY -- params from stored procedure for pagination, not relevant to example

So we get all results ordered by MainCol

But the results with MainCol = 1 get ordered by ColX

And the results with MainCol = 0 get ordered by ColY

You can also use the FileReader class :

    var reader = new FileReader();
    reader.onload = function (e) {
        var data = this.result;
    }
    reader.readAsDataURL( file );

}

After all these months have passed after the original question, it's now worth pointing out that Microsoft has devised a solution of their own. See http://blogs.msdn.com/b/vbertocci/archive/2012/11/20/introducing-the-developer-preview-of-the-json-web-token-handler-for-the-microsoft-net-framework-4-5.aspx for details.

One solution could be to wrap the options inside optgroup:

optgroup { font-size:40px; }

<select>
  <optgroup>
    <option selected="selected" class="service-small">Service area?</option>
    <option class="service-small">Volunteering</option>
    <option class="service-small">Partnership &amp; Support</option>
    <option class="service-small">Business Services</option>
  </optgroup>
</select>

With the newer versions of angularjs the correct answer to this question is to use ng-if:

<ul>
  <li ng-if="list.length === 0">( No items in this list yet! )</li>
  <li ng-repeat="item in list">{{ item }}</li>
</ul>

This solution will not flicker when the list is about to download either because the list has to be defined and with a length of 0 for the message to display.

Here is a plunker to show it in use: http://plnkr.co/edit/in7ha1wTlpuVgamiOblS?p=preview

Tip: You can also show a loading text or spinner:

  <li ng-if="!list">( Loading... )</li>

console.log() in java is System.out.println(); to put text on the next line

And System.out.print(); puts text on the same line.

If you have date object like

var date = new Date('2017/12/03');

then there is inbuilt method in javascript for getting date in milliseconds format which is valueOf()

date.valueOf(); //1512239400000 in milliseconds format

C99 requires that when a/b is representable:

(a/b) * b + a%b shall equal a

This makes sense, logically. Right?

Let's see what this leads to:

Example A. 5/(-3) is -1

=> (-1) * (-3) + 5%(-3) = 5

This can only happen if 5%(-3) is 2.

Example B. (-5)/3 is -1

=> (-1) * 3 + (-5)%3 = -5

This can only happen if (-5)%3 is -2

Angularjs Dependency Injection framework is responsible for injecting the dependancies of you app module to your controllers. This is possible through its injector.

You need to first identify the ng-app and get the associated injector. The below query works to find your ng-app in the DOM and retrieve the injector.

angular.element('*[ng-app]').injector()

In chrome, however, you can point to target ng-app as shown below. and use the $0 hack and issue angular.element($0).injector()

Once you have the injector, get any dependency injected service as below

injector = angular.element($0).injector();
injector.get('$mdToast');

It wasn't working because your image was too big - there are restrictions on the image dimensions. In Firefox, for example, the size limit is 128x128px. See this page for more details.

Additionally, you also have to add in auto.

jsFiddle demo here - note that's an actual image, and not a default cursor.

.test {_x000D_
  background:gray;_x000D_
  width:200px;_x000D_
  height:200px;_x000D_
  cursor:url(http://www.javascriptkit.com/dhtmltutors/cursor-hand.gif), auto;_x000D_
}

<div class="test">TEST</div>

type='Submit' is set to forward & get the values on BACK-END (PHP, .NET etc). type='button' will reflect normal button behavior.

The above code is working for me.

You can use the following code to generate a requirements.txt file:

pip install pipreqs

pipreqs /path/to/project

more info related to pipreqs can be found here.

Sometimes you come across pip freeze, but this saves all packages in the environment including those that you don't use in your current project.

I'm using NetBeans and needed a solution for this also. After googleling around and starting from Christopher's answer i managed to build a script that helps you easily do this in NetBeans. I'm putting the instructions here in case someone else will need them.

What you have to do is download one-jar. You can use the link from here: http://one-jar.sourceforge.net/index.php?page=getting-started&file=ant Extract the jar archive and look for one-jar\dist folder that contains one-jar-ant-task-.jar, one-jar-ant-task.xml and one-jar-boot-.jar. Extract them or copy them to a path that we will add to the script below, as the value of the property one-jar.dist.dir.

Just copy the following script at the end of your build.xml script (from your NetBeans project), just before /project tag, replace the value for one-jar.dist.dir with the correct path and run one-jar target.

For those of you that are unfamiliar with running targets, this tutorial might help: http://www.oracle.com/technetwork/articles/javase/index-139904.html . It also shows you how to place sources into one jar, but they are exploded, not compressed into jars.

<property name="one-jar.dist.dir" value="path\to\one-jar-ant"/>
<import file="${one-jar.dist.dir}/one-jar-ant-task.xml" optional="true" />

<target name="one-jar" depends="jar">
<property name="debuglevel" value="source,lines,vars"/>
<property name="target" value="1.6"/>
<property name="source" value="1.6"/>
<property name="src.dir"          value="src"/>
<property name="bin.dir"          value="bin"/>
<property name="build.dir"        value="build"/>
<property name="dist.dir"         value="dist"/>
<property name="external.lib.dir" value="${dist.dir}/lib"/>
<property name="classes.dir"      value="${build.dir}/classes"/>
<property name="jar.target.dir"   value="${build.dir}/jars"/>
<property name="final.jar"        value="${dist.dir}/${ant.project.name}.jar"/>
<property name="main.class"       value="${main.class}"/>

<path id="project.classpath">
    <fileset dir="${external.lib.dir}">
        <include name="*.jar"/>
    </fileset>
</path>

<mkdir dir="${bin.dir}"/>
<!-- <mkdir dir="${build.dir}"/> -->
<!-- <mkdir dir="${classes.dir}"/> -->
<mkdir dir="${jar.target.dir}"/>
<copy includeemptydirs="false" todir="${classes.dir}">
    <fileset dir="${src.dir}">
        <exclude name="**/*.launch"/>
        <exclude name="**/*.java"/>
    </fileset>
</copy>

<!-- <echo message="${ant.project.name}: ${ant.file}"/> -->
<javac debug="true" debuglevel="${debuglevel}" destdir="${classes.dir}" source="${source}" target="${target}">
    <src path="${src.dir}"/>
    <classpath refid="project.classpath"/>   
</javac>

<delete file="${final.jar}" />
<one-jar destfile="${final.jar}" onejarmainclass="${main.class}">
    <main>
        <fileset dir="${classes.dir}"/>
    </main>
    <lib>
        <fileset dir="${external.lib.dir}" />
    </lib>
</one-jar>

<delete dir="${jar.target.dir}"/>

</target>

Best of luck and don't forget to vote up if it helped you.

You can also use the TimeUnit class. You could define

private static final String FORMAT = "%02d:%02d:%02d";

public static String parseTime(long milliseconds) {
      return String.format(FORMAT,
              TimeUnit.MILLISECONDS.toHours(milliseconds),
              TimeUnit.MILLISECONDS.toMinutes(milliseconds) - TimeUnit.HOURS.toMinutes(
              TimeUnit.MILLISECONDS.toHours(milliseconds)),
              TimeUnit.MILLISECONDS.toSeconds(milliseconds) - TimeUnit.MINUTES.toSeconds(
              TimeUnit.MILLISECONDS.toMinutes(milliseconds)));
   }

just

pecl uninstall module_name

then

pecl install module_name

This depends. If you are concerned that your variable could end up as something that resolves to TRUE. Then hard checking is a must. Otherwise it is up to you. However, I doubt that the syntax whatever == TRUE would ever confuse anyone who knew what they were doing.

If you use the WEB API with Claims, you can use this:

[AttributeUsage(AttributeTargets.Method | AttributeTargets.Class, Inherited = true, AllowMultiple = true)]
public class AutorizeCompanyAttribute:  AuthorizationFilterAttribute
{
    public string Company { get; set; }

    public override void OnAuthorization(HttpActionContext actionContext)
    {
        var claims = ((ClaimsIdentity)Thread.CurrentPrincipal.Identity);
        var claim = claims.Claims.Where(x => x.Type == "Company").FirstOrDefault();

        string privilegeLevels = string.Join("", claim.Value);        

        if (privilegeLevels.Contains(this.Company)==false)
        {
            actionContext.Response = actionContext.Request.CreateResponse(HttpStatusCode.Unauthorized, "Usuario de Empresa No Autorizado");
        }
    }
}
[HttpGet]
[AutorizeCompany(Company = "MyCompany")]
[Authorize(Roles ="SuperAdmin")]
public IEnumerable MyAction()
{....
}

If you work with rails and you have the keys in a separate list, you can use the * notation:

keys = [:foo, :bar]
hash1 = {foo: 1, bar:2, baz: 3}
hash2 = hash1.slice(*keys)
=> {foo: 1, bar:2}

As other answers stated, you can also use slice! to modify the hash in place (and return the erased key/values).

Please Check URL you have pasted and It takes additional h after clone.

So either you have paste full git clone http://<URL>.git or just remove additional letter before git repository URL.

I had the same problem.

Solved by sharing internet connection (on the hosting OS).

Network Connection Properties -> advanced -> Allow other users to connect...

#include<algorithm>
#include<vector>
#include<iostream>
using namespace std;
int main()
{
    vector<int>v1;
    for(int i=0; i<5; i++)
        v1.push_back(i*2);
    for(int i=0; i<v1.size(); i++)
        cout<<v1[i];    //02468
    reverse(v1.begin(),v1.end());
    
    for(int i=0; i<v1.size(); i++)
        cout<<v1[i];   //86420
}

Select the contents of the row like this:

$(row).contents().slideDown();

.contents() - Get the children of each element in the set of matched elements, including text and comment nodes.

This is only due to javahome path missing.

Use the command line below:--

For Windows OS- Open your command prompt

netbeans-6.5.1-windows.exe --javahome "C:\\Program Files\Java\jdk1.5.0"

For Linux OS- Open your Terminal

netbeans-6.5.1-windows.sh --javahome /usr/jdk/jdk1.6.0_04

The problem solved.

Renderer has been deprecated in Angular 4.0.0-rc.1, read the update below

The angular2 way is to use listen or listenGlobal from Renderer

For example, if you want to add a click event to a Component, you have to use Renderer and ElementRef (this gives you as well the option to use ViewChild, or anything that retrieves the nativeElement)

constructor(elementRef: ElementRef, renderer: Renderer) {

    // Listen to click events in the component
    renderer.listen(elementRef.nativeElement, 'click', (event) => {
      // Do something with 'event'
    })
);

You can use listenGlobal that will give you access to document, body, etc.

renderer.listenGlobal('document', 'click', (event) => {
  // Do something with 'event'
});

Note that since beta.2 both listen and listenGlobal return a function to remove the listener (see breaking changes section from changelog for beta.2). This is to avoid memory leaks in big applications (see #6686).

So to remove the listener we added dynamically we must assign listen or listenGlobal to a variable that will hold the function returned, and then we execute it.

// listenFunc will hold the function returned by "renderer.listen"
listenFunc: Function;

// globalListenFunc will hold the function returned by "renderer.listenGlobal"
globalListenFunc: Function;

constructor(elementRef: ElementRef, renderer: Renderer) {
    
    // We cache the function "listen" returns
    this.listenFunc = renderer.listen(elementRef.nativeElement, 'click', (event) => {
        // Do something with 'event'
    });

    // We cache the function "listenGlobal" returns
    this.globalListenFunc = renderer.listenGlobal('document', 'click', (event) => {
        // Do something with 'event'
    });
}

ngOnDestroy() {
    // We execute both functions to remove the respectives listeners

    // Removes "listen" listener
    this.listenFunc();
    
    // Removs "listenGlobal" listener
    this.globalListenFunc();
}

Here's a plnkr with an example working. The example contains the usage of listen and listenGlobal.

Using RendererV2 with Angular 4.0.0-rc.1+ ^{_{(Renderer2 since 4.0.0-rc.3)}}

• 25/02/2017: Renderer has been deprecated, now we should use RendererV2 (see line below). See the commit.

• 10/03/2017: RendererV2 was renamed to Renderer2. See the breaking changes.

RendererV2 has no more listenGlobal function for global events (document, body, window). It only has a listen function which achieves both functionalities.

For reference, I'm copy & pasting the source code of the DOM Renderer implementation since it may change (yes, it's angular!).

listen(target: 'window'|'document'|'body'|any, event: string, callback: (event: any) => boolean):
      () => void {
    if (typeof target === 'string') {
      return <() => void>this.eventManager.addGlobalEventListener(
          target, event, decoratePreventDefault(callback));
    }
    return <() => void>this.eventManager.addEventListener(
               target, event, decoratePreventDefault(callback)) as() => void;
  }

As you can see, now it verifies if we're passing a string (document, body or window), in which case it will use an internal addGlobalEventListener function. In any other case, when we pass an element (nativeElement) it will use a simple addEventListener

To remove the listener it's the same as it was with Renderer in angular 2.x. listen returns a function, then call that function.

Example

// Add listeners
let global = this.renderer.listen('document', 'click', (evt) => {
  console.log('Clicking the document', evt);
})

let simple = this.renderer.listen(this.myButton.nativeElement, 'click', (evt) => {
  console.log('Clicking the button', evt);
});

// Remove listeners
global();
simple();

You can get deadlocks on more than just row locks, e.g. see this. The scripts may be competing for other resources, such as index blocks.

I've gotten around this in the past by engineering the parallelism in such a way that different instances are working on portions of the workload that are less likely to affect blocks that are close to each other; for example, for an update of a large table, instead of setting up the parallel slaves using something like MOD(n,10), I'd use TRUNC(n/10) which mean that each slave worked on a contiguous set of data.

There are, of course, much better ways of splitting up a job for parallelism, e.g. DBMS_PARALLEL_EXECUTE.

Not sure why you're getting "PL/SQL successfully completed", perhaps your scripts are handling the exception?

I believe there are two answers. One using 'pure' Javascript with IIFE function to hide its auxiliary construction functions. And the other using a NodeJS module to also hide its auxiliary construction functions.

I will show only the example with a NodeJS module.

Class Vector2d.js:

/*

    Implement a class of type Vetor2d with three types of constructors.

*/

// If a constructor function is successfully executed,
// must have its value changed to 'true'.let global_wasExecuted = false;  
global_wasExecuted = false;   

//Tests whether number_value is a numeric type
function isNumber(number_value) {
    
    let hasError = !(typeof number_value === 'number') || !isFinite(number_value);

    if (hasError === false){
        hasError = isNaN(number_value);
    }

    return !hasError;
}

// Object with 'x' and 'y' properties associated with its values.
function vector(x,y){
    return {'x': x, 'y': y};
}

//constructor in case x and y are 'undefined'
function new_vector_zero(x, y){

    if (x === undefined && y === undefined){
        global_wasExecuted = true;
        return new vector(0,0);
    }
}

//constructor in case x and y are numbers
function new_vector_numbers(x, y){

    let x_isNumber = isNumber(x);
    let y_isNumber = isNumber(y);

    if (x_isNumber && y_isNumber){
        global_wasExecuted = true;
        return new vector(x,y);
    }
}

//constructor in case x is an object and y is any
//thing (he is ignored!)
function new_vector_object(x, y){

    let x_ehObject = typeof x === 'object';
    //ignore y type

    if (x_ehObject){

        //assigns the object only for clarity of code
        let x_object = x;

        //tests whether x_object has the properties 'x' and 'y'
        if ('x' in x_object && 'y' in x_object){

            global_wasExecuted = true;

            /*
            we only know that x_object has the properties 'x' and 'y',
            now we will test if the property values ??are valid,
            calling the class constructor again.            
            */
            return new Vector2d(x_object.x, x_object.y);
        }

    }
}


//Function that returns an array of constructor functions
function constructors(){
    let c = [];
    c.push(new_vector_zero);
    c.push(new_vector_numbers);
    c.push(new_vector_object);

    /*
        Your imagination is the limit!
        Create as many construction functions as you want.    
    */

    return c;
}

    constructor(x, y){

        //returns an array of constructor functions
        let my_constructors = constructors();

            new_vector = my_constructors[index](x,y);
            
            if (global_wasExecuted) {
            
                this.x = new_vector.x;
                this.y = new_vector.y;

                break; 
            };
        };
    }

    toString(){
        return `(x: ${this.x}, y: ${this.y})`;
    }

}

//Only the 'Vector2d' class will be visible externally
module.exports = Vector2d;  

The useVector2d.js file uses the Vector2d.js module:

const Vector = require('./Vector2d');

let v1 = new Vector({x: 2, y: 3});
console.log(`v1 = ${v1.toString()}`);

let v2 = new Vector(1, 5.2);
console.log(`v2 = ${v2.toString()}`);

let v3 = new Vector();
console.log(`v3 = ${v3.toString()}`);

Terminal output:

v1 = (x: 2, y: 3)
v2 = (x: 1, y: 5.2)
v3 = (x: 0, y: 0)

With this we avoid dirty code (many if's and switch's spread throughout the code), difficult to maintain and test. Each building function knows which conditions to test. Increasing and / or decreasing your building functions is now simple.

When I ran taskkill to stop the javaw.exe process it would say it had terminated but remained running. The jqs process (java qucikstart) needs to be stopped also. Running this batch file took care of the issue.

taskkill /f /im jqs.exe
taskkill /f /im javaw.exe
taskkill /f /im java.exe

@RobinL as mentioned in previous comments, you can use chart.series[n].setData(). First you need to make sure you’ve assigned a chart instance to the chart variable, that way it adopts all the properties and methods you need to access and manipulate the chart.

I’ve also used the second parameter of setData() and had it false, to prevent automatic rendering of the chart. This was because I have multiple data series, so I’ll rather update each of them, with render=false, and then running chart.redraw(). This multiplied performance (I’m having 10,000-100,000 data points and refreshing the data set every 50 milliseconds).

If you want to get started with Java, you will be much happier with a Java IDE. IntelliJ Community Edition, Eclipse, and Netbeans are all free.

I know IntelliJ can be set to use Visual Studio keyboard shortcuts, so even if you are a keyboard junkie like myself, you won't feel out of place in a Java IDE.

The differences in IDEs are minimal, and the time you will save by using a Java IDE for Java development will be huge.

Good luck!

Note the guidelines for performing work on a UI thread, collected on my blog:

• Don't block the UI thread for more than 50ms at a time.
• You can schedule ~100 continuations on the UI thread per second; 1000 is too much.

There are two techniques you should use:

1) Use ConfigureAwait(false) when you can.

E.g., await MyAsync().ConfigureAwait(false); instead of await MyAsync();.

ConfigureAwait(false) tells the await that you do not need to resume on the current context (in this case, "on the current context" means "on the UI thread"). However, for the rest of that async method (after the ConfigureAwait), you cannot do anything that assumes you're in the current context (e.g., update UI elements).

For more information, see my MSDN article Best Practices in Asynchronous Programming.

2) Use Task.Run to call CPU-bound methods.

You should use Task.Run, but not within any code you want to be reusable (i.e., library code). So you use Task.Run to call the method, not as part of the implementation of the method.

So purely CPU-bound work would look like this:

// Documentation: This method is CPU-bound.
void DoWork();

Which you would call using Task.Run:

await Task.Run(() => DoWork());

Methods that are a mixture of CPU-bound and I/O-bound should have an Async signature with documentation pointing out their CPU-bound nature:

// Documentation: This method is CPU-bound.
Task DoWorkAsync();

Which you would also call using Task.Run (since it is partially CPU-bound):

await Task.Run(() => DoWorkAsync());

You can also do this without using groupby or loc. By simply including the condition in code. Let the name of dataframe be df. Then you can try :

df[df['a']==1]['b'].sum()

or you can also try :

sum(df[df['a']==1]['b'])

Another way could be to use the numpy library of python :

import numpy as np
print(np.where(df['a']==1, df['b'],0).sum())

A simple solution using fscanf:

void read_ints (const char* file_name)
{
  FILE* file = fopen (file_name, "r");
  int i = 0;

  fscanf (file, "%d", &i);    
  while (!feof (file))
    {  
      printf ("%d ", i);
      fscanf (file, "%d", &i);      
    }
  fclose (file);        
}

If the types of your items are all different, here is a class I made to get them more intuitively.

The usage of this class:

var t = TypedTuple.Create("hello", 1, new MyClass());
var s = t.Get<string>();
var i = t.Get<int>();
var c = t.Get<MyClass>();

Use:

function console_log($data) {
    $bt = debug_backtrace();
    $caller = array_shift($bt);

    if (is_array($data))
        $dataPart = implode(',', $data);
    else
        $dataPart = $data;

    $toSplit = $caller['file'])) . ':' .
               $caller['line'] . ' => ' . $dataPart

    error_log(end(split('/', $toSplit));
}

I think you mean cast(floor(cast(getdate()as float))as datetime)

real is only 32-bits, and could lose some information

This is fastest cast(cast(getdate()+x-0.5 as int)as datetime)

...though only about 10% faster(about 0.49 microseconds CPU vs. 0.58)

This was recommended, and takes the same time in my test just now: DATEADD(dd, DATEDIFF(dd, 0, getdate()), 0)

In SQL 2008, the SQL CLR function is about 5 times faster than using a SQL function would be, at 1.35 microseconds versus 6.5 microsections, indicating much lower function-call overhead for a SQL CLR function versus a simple SQL UDF.

In SQL 2005, the SQL CLR function is 16 times faster, per my testing, versus this slow function:

create function dateonly (  @dt datetime )
returns datetime
as
begin
return cast(floor(cast(@dt as float))as int)
end

If you are mocking the behavior (with something like doNothing()) there should really be no need to call to verify*(). That said, here's my stab at re-writing your test method:

@PrepareForTest({InternalUtils.class})
@RunWith(PowerMockRunner.class)
public class InternalServiceTest { //Note the renaming of the test class.
   public void testProcessOrder() {
        //Variables
        InternalService is = new InternalService();
        Order order = mock(Order.class);

        //Mock Behavior
        when(order.isSuccessful()).thenReturn(true);
        mockStatic(Internalutils.class);
        doNothing().when(InternalUtils.class); //This is the preferred way
                                               //to mock static void methods.
        InternalUtils.sendEmail(anyString(), anyString(), anyString(), anyString());

        //Execute
        is.processOrder(order);            

        //Verify
        verifyStatic(InternalUtils.class); //Similar to how you mock static methods
                                           //this is how you verify them.
        InternalUtils.sendEmail(anyString(), anyString(), anyString(), anyString());
   }
}

I grouped into four sections to better highlight what is going on:

1. Variables

I choose to declare any instance variables / method arguments / mock collaborators here. If it is something used in multiple tests, consider making it an instance variable of the test class.

2. Mock Behavior

This is where you define the behavior of all of your mocks. You're setting up return values and expectations here, prior to executing the code under test. Generally speaking, if you set the mock behavior here you wouldn't need to verify the behavior later.

3. Execute

Nothing fancy here; this just kicks off the code being tested. I like to give it its own section to call attention to it.

4. Verify

This is when you call any method starting with verify or assert. After the test is over, you check that the things you wanted to have happen actually did happen. That is the biggest mistake I see with your test method; you attempted to verify the method call before it was ever given a chance to run. Second to that is you never specified which static method you wanted to verify.

Additional Notes

This is mostly personal preference on my part. There is a certain order you need to do things in but within each grouping there is a little wiggle room. This helps me quickly separate out what is happening where.

I also highly recommend going through the examples at the following sites as they are very robust and can help with the majority of the cases you'll need:

• https://github.com/powermock/powermock/wiki/Mockito (PowerMock Overview / Examples)
• http://site.mockito.org/mockito/docs/current/org/mockito/Mockito.html (Mockito Overview / Examples)

In regards to @bmasterswizzle's BRILLIANT answer - more specifically - to @DanRamos' question about how to force the new interface's link-state to "up".. I use this script, of whose origin I cannot recall, but which works fabulously (in coordination with @bmasterswizzles "Mona Lisa" of answers)...

#!/bin/zsh

[[ "$UID" -ne "0" ]] && echo "You must be root. Goodbye..." && exit 1
echo "starting"
exec 4<>/dev/tap0
ifconfig tap0 10.10.10.1 10.10.10.255
ifconfig tap0 up
ping -c1 10.10.10.1
echo "ending"
export PS1="tap interface>"
dd of=/dev/null <&4 & # continuously reads from buffer and dumps to null

I am NOT quite sure I understand the alteration to the prompt at the end, or...

dd of=/dev/null <&4 & # continuously reads from buffer and dumps to null

but WHATEVER. it works. link light: green?. loves it.

If you use the JQuery library you can use the .hover() event which merges the mouseover and mouseout event and helps you with the timing and child elements:

$(this).hover(function(){},function(){});

The first function is the start of the hover and the next is the end. Read more at: http://docs.jquery.com/Events/hover

1) The most simple way would be using WMPLib

WMPLib.WindowsMediaPlayer Player;

private void PlayFile(String url)
{
    Player = new WMPLib.WindowsMediaPlayer();
    Player.PlayStateChange += Player_PlayStateChange;
    Player.URL = url;
    Player.controls.play();
}

private void Player_PlayStateChange(int NewState)
{
    if ((WMPLib.WMPPlayState)NewState == WMPLib.WMPPlayState.wmppsStopped)
    {
        //Actions on stop
    }
}

2) Alternatively you can use the open source library NAudio. It can play mp3 files using different methods and actually offers much more than just playing a file.

This is as simple as

using NAudio;
using NAudio.Wave;

IWavePlayer waveOutDevice = new WaveOut();
AudioFileReader audioFileReader = new AudioFileReader("Hadouken! - Ugly.mp3");

waveOutDevice.Init(audioFileReader);
waveOutDevice.Play();

Don't forget to dispose after the stop

waveOutDevice.Stop();
audioFileReader.Dispose();
waveOutDevice.Dispose();
