You could also you Point2D Java API class:

public static double distance(double x1, double y1, double x2, double y2)

Example:

double distance = Point2D.distance(3.0, 4.0, 5.0, 6.0);
System.out.println("The distance between the points is " + distance);

Yes. Or, rather, no.

Er, I mean, it doesn't matter. Use the one that makes sense for your particular project. PX and EM or both equally valid but will behave a bit different depending on your overall page's CSS architecture.

UPDATE:

To clarify, I'm stating that usually it likely doesn't matter which you use. At times, you may specifically want to choose one over the other. EMs are nice if you can start from scratch and want to use a base font size and make everything relative to that.

PXs are often needed when you're retrofitting a redesign onto an existing code base and need the specificity of px to prevent bad nesting issues.

Here are two functions to calculate distance and bearing, which are based on the code in previous messages and https://gist.github.com/jeromer/2005586 (added tuple type for geographical points in lat, lon format for both functions for clarity). I tested both functions and they seem to work right.

#coding:UTF-8
from math import radians, cos, sin, asin, sqrt, atan2, degrees

def haversine(pointA, pointB):

    if (type(pointA) != tuple) or (type(pointB) != tuple):
        raise TypeError("Only tuples are supported as arguments")

    lat1 = pointA[0]
    lon1 = pointA[1]

    lat2 = pointB[0]
    lon2 = pointB[1]

    # convert decimal degrees to radians 
    lat1, lon1, lat2, lon2 = map(radians, [lat1, lon1, lat2, lon2]) 

    # haversine formula 
    dlon = lon2 - lon1 
    dlat = lat2 - lat1 
    a = sin(dlat/2)**2 + cos(lat1) * cos(lat2) * sin(dlon/2)**2
    c = 2 * asin(sqrt(a)) 
    r = 6371 # Radius of earth in kilometers. Use 3956 for miles
    return c * r


def initial_bearing(pointA, pointB):

    if (type(pointA) != tuple) or (type(pointB) != tuple):
        raise TypeError("Only tuples are supported as arguments")

    lat1 = radians(pointA[0])
    lat2 = radians(pointB[0])

    diffLong = radians(pointB[1] - pointA[1])

    x = sin(diffLong) * cos(lat2)
    y = cos(lat1) * sin(lat2) - (sin(lat1)
            * cos(lat2) * cos(diffLong))

    initial_bearing = atan2(x, y)

    # Now we have the initial bearing but math.atan2 return values
    # from -180° to + 180° which is not what we want for a compass bearing
    # The solution is to normalize the initial bearing as shown below
    initial_bearing = degrees(initial_bearing)
    compass_bearing = (initial_bearing + 360) % 360

    return compass_bearing

pA = (46.2038,6.1530)
pB = (46.449, 30.690)

print haversine(pA, pB)

print initial_bearing(pA, pB)

I implemeneted this algorithm in typescript and ES6

export type Coordinate = {
  lat: number;
  lon: number;
};

get the distance between two points:

function getDistanceBetweenTwoPoints(cord1: Coordinate, cord2: Coordinate) {
  if (cord1.lat == cord2.lat && cord1.lon == cord2.lon) {
    return 0;
  }

  const radlat1 = (Math.PI * cord1.lat) / 180;
  const radlat2 = (Math.PI * cord2.lat) / 180;

  const theta = cord1.lon - cord2.lon;
  const radtheta = (Math.PI * theta) / 180;

  let dist =
    Math.sin(radlat1) * Math.sin(radlat2) +
    Math.cos(radlat1) * Math.cos(radlat2) * Math.cos(radtheta);

  if (dist > 1) {
    dist = 1;
  }

  dist = Math.acos(dist);
  dist = (dist * 180) / Math.PI;
  dist = dist * 60 * 1.1515;
  dist = dist * 1.609344; //convert miles to km
  
  return dist;
}

get the distance between an array of coordinates

export function getTotalDistance(coordinates: Coordinate[]) {
  coordinates = coordinates.filter((cord) => {
    if (cord.lat && cord.lon) {
      return true;
    }
  });
  
  let totalDistance = 0;

  if (!coordinates) {
    return 0;
  }

  if (coordinates.length < 2) {
    return 0;
  }

  for (let i = 0; i < coordinates.length - 2; i++) {
    if (
      !coordinates[i].lon ||
      !coordinates[i].lat ||
      !coordinates[i + 1].lon ||
      !coordinates[i + 1].lat
    ) {
      totalDistance = totalDistance;
    }
    totalDistance =
      totalDistance +
      getDistanceBetweenTwoPoints(coordinates[i], coordinates[i + 1]);
  }

  return totalDistance.toFixed(2);
}

In C++ it is done like this:

#define LOCAL_PI 3.1415926535897932385 

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

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

Here is same thing as the C++ answer but ported to pascal. The order of the point parameter has changed to suit my code but is the same thing.

function Dot(const p1, p2: PointF): double;
begin
  Result := p1.x * p2.x + p1.y * p2.y;
end;
function SubPoint(const p1, p2: PointF): PointF;
begin
  result.x := p1.x - p2.x;
  result.y := p1.y - p2.y;
end;

function ShortestDistance2(const p,v,w : PointF) : double;
var
  l2,t : double;
  projection,tt: PointF;
begin
  // Return minimum distance between line segment vw and point p
  //l2 := length_squared(v, w);  // i.e. |w-v|^2 -  avoid a sqrt
  l2 := Distance(v,w);
  l2 := MPower(l2,2);
  if (l2 = 0.0) then begin
    result:= Distance(p, v);   // v == w case
    exit;
  end;
  // Consider the line extending the segment, parameterized as v + t (w - v).
  // We find projection of point p onto the line.
  // It falls where t = [(p-v) . (w-v)] / |w-v|^2
  t := Dot(SubPoint(p,v),SubPoint(w,v)) / l2;
  if (t < 0.0) then begin
    result := Distance(p, v);       // Beyond the 'v' end of the segment
    exit;
  end
  else if (t > 1.0) then begin
    result := Distance(p, w);  // Beyond the 'w' end of the segment
    exit;
  end;
  //projection := v + t * (w - v);  // Projection falls on the segment
  tt.x := v.x + t * (w.x - v.x);
  tt.y := v.y + t * (w.y - v.y);
  result := Distance(p, tt);
end;

Try This Code. here we have two longitude and latitude values and selected_location.distanceTo(near_locations) function returns the distance between those places in meters.

Location selected_location = new Location("locationA");
            selected_location.setLatitude(17.372102);
            selected_location.setLongitude(78.484196);
Location near_locations = new Location("locationB");
            near_locations.setLatitude(17.375775);
            near_locations.setLongitude(78.469218);
double distance = selected_location.distanceTo(near_locations);

here "distance" is distance between locationA & locationB (in Meters)

So simple just use abs((a) - (b)).

will work seamless without any additional care in signs(positive , negative)

def get_distance(p1,p2):
     return abs((p1) - (p2))

get_distance(0,2)
2

get_distance(0,2)
2

get_distance(-2,0)
2

get_distance(2,-1)
3

get_distance(-2,-1)
1

You should use this command to set the global installation flocation of npm packages

(git bash) npm config --global set prefix </path/you/want/to/use>/npm

(cmd/git-cmd) npm config --global set prefix <drive:\path\you\want\to\use>\npm

You may also consider the npm-cache location right next to it. (as would be in a normal nodejs installation on windows)

(git bash) npm config --global set cache </path/you/want/to/use>/npm-cache

(cmd/git-cmd) npm config --global set cache <drive:\path\you\want\to\use>\npm-cache

I am using Android 10 in MiA2. The mistake I was making is that I tried to install the app via ES Explorer. I tried Settings -> Apps & Notifications -> Advanced -> Special App Access -> Install Unknown Apps -> ES File Manage -> Allow from this source. Even then the app won't install.

Then I tired to install the app using the default File Manager and it installed easily.

I answered a similar question before on how to run a Docker container inside Docker.

To run docker inside docker is definitely possible. The main thing is that you run the outer container with extra privileges (starting with --privileged=true) and then install docker in that container.

Check this blog post for more info: Docker-in-Docker.

One potential use case for this is described in this entry. The blog describes how to build docker containers within a Jenkins docker container.

However, Docker inside Docker it is not the recommended approach to solve this type of problems. Instead, the recommended approach is to create "sibling" containers as described in this post

So, running Docker inside Docker was by many considered as a good type of solution for this type of problems. Now, the trend is to use "sibling" containers instead. See the answer by @predmijat on this page for more info.

Add a static method inside your functional interface

package example;

interface Action<T, U> {
       U execute(T t);
       static  Action<Void,Void> invoke(Runnable runnable){
           return (v) -> {
               runnable.run();
                return null;
            };         
       }
    }

public class Lambda {


    public static void main(String[] args) {

        Action<Void, Void> a = Action.invoke(() -> System.out.println("Do nothing!"));
        Void t = null;
        a.execute(t);
    }

}

Output

Do nothing!

Here's my solution using React Hooks. It combines the spread operator and the ternary operator.

style.js

export default {
  normal:{
    background: 'purple',
    color: '#ffffff'
  },
  hover: {
    background: 'red'
  }
}

Button.js

import React, {useState} from 'react';
import style from './style.js'

function Button(){

  const [hover, setHover] = useState(false);

  return(
    <button
      onMouseEnter={()=>{
        setHover(true);
      }}
      onMouseLeave={()=>{
        setHover(false);
      }}
      style={{
        ...style.normal,
        ...(hover ? style.hover : null)
      }}>

        MyButtonText

    </button>
  )
}

Try the sql server management studio (version 2008 or earlier) from Microsoft. Download it from here. Not sure about the license, but it seems to be free if you download the EXPRESS EDITION.

You might also be able to use later editions of SSMS. For 2016, you will need to install an extension.

If you have the option you can copy the sdf file to a different machine which you are allowed to pollute with additional software.

Update: comment from Nick Westgate in nice formatting

The steps are not all that intuitive:

1. Open SQL Server Management Studio, or if it's running select File -> Connect Object Explorer...
2. In the Connect to Server dialog change Server type to SQL Server Compact Edition
3. From the Database file dropdown select < Browse for more...>
4. Open your SDF file.

Not sure if this is really beneficial or why I prefer this style but what I do (in vanilla js) is:

document.querySelector('#selector').toggleAttribute('data-something');

This will add the attribute in all lowercase without a value or remove it if it already exists on the element.

I have encountered similar myself before for 2 reasons; 1. MVC is not installed. 2. The url routing module is not registered (this varies by machine in my workplace for a reason I cannot fully explain - it is not always registered at a system level ), try registering it in the application web.config:

<system.web> 
      ... 
      <httpModules> 
         ... 
         <add name="UrlRoutingModule" type="System.Web.Routing.UrlRoutingModule, System.Web.Routing, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> 
      </httpModules>
   </system.web>

Edit: I forgot to add the location for iis 7+:

<system.webServer> 

      <modules> 
         ... 
         <add name="UrlRoutingModule" type="System.Web.Routing.UrlRoutingModule, System.Web.Routing, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> 
      </modules>
</system.webServer>

What you see is the interpreter echoing back the return value of next() in addition to i being printed each iteration:

>>> a = iter(list(range(10)))
>>> for i in a:
...    print(i)
...    next(a)
... 
0
1
2
3
4
5
6
7
8
9

So 0 is the output of print(i), 1 the return value from next(), echoed by the interactive interpreter, etc. There are just 5 iterations, each iteration resulting in 2 lines being written to the terminal.

If you assign the output of next() things work as expected:

>>> a = iter(list(range(10)))
>>> for i in a:
...    print(i)
...    _ = next(a)
... 
0
2
4
6
8

or print extra information to differentiate the print() output from the interactive interpreter echo:

>>> a = iter(list(range(10)))
>>> for i in a:
...    print('Printing: {}'.format(i))
...    next(a)
... 
Printing: 0
1
Printing: 2
3
Printing: 4
5
Printing: 6
7
Printing: 8
9

In other words, next() is working as expected, but because it returns the next value from the iterator, echoed by the interactive interpreter, you are led to believe that the loop has its own iterator copy somehow.

Do this:

>>> d = [ [ None for y in range( 2 ) ] for x in range( 2 ) ]
>>> d
[[None, None], [None, None]]
>>> d[0][0] = 1
>>> d
[[1, None], [None, None]]

The other solutions will lead to this kind of problem:

>>> d = [ [ None ] * 2 ] * 2
>>> d
[[None, None], [None, None]]
>>> d[0][0] = 1
>>> d
[[1, None], [1, None]]

From the Gnuplot documentation. To draw a vertical line from the bottom to the top of the graph at x=3, use:

set arrow from 3, graph 0 to 3, graph 1 nohead

Kind of backward way, but without exec/system:

file_put_contents("testFile", "test");
$user = fileowner("testFile");
unlink("testFile");

If you create a file, the owner will be the PHP user.

This could also likely be run with any of the temporary file functions such as tempnam(), which creates a random file in the temporary directory and returns the name of that file. If there are issues due to something like the permissions, open_basedir or safe mode that prevent writing a file, typically, the temp directory will still be allowed.

If the button is located between the form tags, I prefer this version:

$('.my-button').click(function (event) {
    var $target = $( event.target );
    $target.closest("form").submit();
});

There is no import aliasing mechanism in Java. You cannot import two classes with the same name and use both of them unqualified.

Import one class and use the fully qualified name for the other one, i.e.

import com.text.Formatter;

private Formatter textFormatter;
private com.json.Formatter jsonFormatter;

Something like this:

  public static void main(String[] args) {
   String N = "ABCD";
   char[] array = N.toCharArray();

   // and as you can see:
    System.out.println(array[0]);
    System.out.println(array[1]);
    System.out.println(array[2]);
  }

Try this:

$array_one = ['ratio_type'];
$array_two = ['ratio_type', 'ratio_type'];
$array_three = ['ratio_type'];
$array_four = ['ratio_type'];
$array_five = ['ratio_type', 'ratio_type', 'ratio_type'];
$array_six = ['ratio_type'];
$array_seven = ['ratio_type'];
$array_eight = ['ratio_type'];

$all_array_elements = array_merge_recursive(
    $array_one,
    $array_two,
    $array_three,
    $array_four,
    $array_five,
    $array_six,
    $array_seven,
    $array_eight
);

foreach ($all_array_elements as $key => $value) {
    echo "[$key]" . ' - ' . $value . PHP_EOL;
}

// OR
var_dump($all_array_elements);

Look at how Runtime.getRuntime().exec() passes the String command to the ProcessBuilder. It uses a tokenizer and explodes the command into individual tokens, then invokes exec(String[] cmdarray, ......) which constructs a ProcessBuilder.

If you construct the ProcessBuilder with an array of strings instead of a single one, you'll get to the same result.

The ProcessBuilder constructor takes a String... vararg, so passing the whole command as a single String has the same effect as invoking that command in quotes in a terminal:

shell$ "command with args"

You repository is bare, i.e. it does not have a working tree attached to it. You can clone it locally to create a working tree for it, or you could use one of several other options to tell Git where the working tree is, e.g. the --work-tree option for single commands, or the GIT_WORK_TREE environment variable. There is also the core.worktree configuration option but it will not work in a bare repository (check the man page for what it does).

# git --work-tree=/path/to/work/tree checkout master
# GIT_WORK_TREE=/path/to/work/tree git status

substring() needs to become substr().

Example: jsfiddle.net/xqyWV

what worked for me was using this:

$data = $request->request->all();
$name = $data['form']['name'];

there is no timeout, by default.

If you need to make single element you can use this construction:

$('<option/>', {
    'class': this.dataID,
    'text': this.s_dataValue
}).appendTo('.subCategory');

But if you need to print many elements you can use this construction:

function printOptions(arr){
    jQuery.each(arr, function(){
        $('<option/>', {
            'value': this.dataID,
            'text': this.s_dataValue
        }).appendTo('.subCategory');
    });
}

Some thing like this.

2020 Updated Answer

It is 2020 (7 years later) and I have learned more about Linux during this time. Specifically that it might not be a good idea to run sudo make install when installing libraries, as these may interfere with the package management system. (In this case apt as I am using Debian 10.)

If this is not correct, please correct me in the comments.

Alternative proposed solution

This information is taken from the GLFW docs, however I have expanded/streamlined the information which is relevant to Linux users.

• Go to home directory and clone glfw repository from github

cd ~
git clone https://github.com/glfw/glfw.git
cd glfw

• You can at this point create a build directory and follow the instructions here (glfw build instructions), however I chose not to do that. The following command still seems to work in 2020 however it is not explicitly stated by the glfw online instructions.

cmake -G "Unix Makefiles"

• You may need to run sudo apt-get build-dep glfw3 before (?). I ran both this command and sudo apt install xorg-dev as per the instructions.

• Finally run make

• Now in your project directory, do the following. (Go to your project which uses the glfw libs)

• Create a CMakeLists.txt, mine looks like this

CMAKE_MINIMUM_REQUIRED(VERSION 3.7)
PROJECT(project)

SET(CMAKE_CXX_STANDARD 14)
SET(CMAKE_BUILD_TYPE DEBUG)

set(GLFW_BUILD_DOCS OFF CACHE BOOL "" FORCE)
set(GLFW_BUILD_TESTS OFF CACHE BOOL "" FORCE)
set(GLFW_BUILD_EXAMPLES OFF CACHE BOOL "" FORCE)

add_subdirectory(/home/<user>/glfw /home/<user>/glfw/src)


FIND_PACKAGE(OpenGL REQUIRED)

SET(SOURCE_FILES main.cpp)

ADD_EXECUTABLE(project ${SOURCE_FILES})
TARGET_LINK_LIBRARIES(project glfw)
TARGET_LINK_LIBRARIES(project OpenGL::GL)

• If you don't like CMake then I appologize but in my opinion it is the easiest way to get your project working quickly. I would recommend learning to use it, at least to a basic level. Regretably I do not know of any good CMake tutorial

• Then do cmake . and make, your project should be built and linked against glfw3 shared lib

• There is some way of creating a dynamic linked lib. I believe I have used the static method here. Please comment / add a section in this answer below if you know more than I do

• This should work on other systems, if not let me know and I will help if I am able to

Another suggestion. One directive with selector.

HTML:

<button type="button" scroll-to="#catalogSection">Scroll To</button>

Angular:

app.directive('scrollTo', function () {
    return {
        restrict: 'A',
        link: function (scope, element, attrs) {
            element.on('click', function () {

                var target = $(attrs.scrollTo);
                if (target.length > 0) {
                    $('html, body').animate({
                        scrollTop: target.offset().top
                    });
                }
            });
        }
    }
});

Also notice $anchorScroll

go to http://nodejs.org/

and hit the button that says "Download For ..."

This'll download the .msi (or .pkg for mac) which will do all the installation and paths for you, unlike the selected answer.

You need to remove "in" from "collapse in"

It's possible to inject instance of ApplicationContext class by using SpringClassRule and SpringMethodRule rules. It might be very handy if you would like to use another non-Spring runners. Here's an example:

@ContextConfiguration(classes = BeanConfiguration.class)
public static class SpringRuleUsage {

    @ClassRule
    public static final SpringClassRule springClassRule = new SpringClassRule();

    @Rule
    public final SpringMethodRule springMethodRule = new SpringMethodRule();

    @Autowired
    private ApplicationContext context;

    @Test
    public void shouldInjectContext() {
    }
}

Just include windows.h instead of stdfax or create a clean project without template.

Sort of an old thread, but I had this same issue today so adding the solution for my problem which nobody has mentioned above.

My date data was downloaded from a csv file but the date came with a Timezone at the end (e.g. 9/7/2018 9:43:42 AM PDT). Excel allows it to be formatted as a date column but apparently does not like the timezone (i.e. PDT) at the end for sorting.

I removed the timezone at the end & then the sorting works.

I did: (1) Format as time (mm/dd/yy xx:xx PM) (2) Search for "M PDT" & replace all with "M" (3) Then sort gives you "Oldest to Newest" sort instead of "A to Z".

Note that all my datetimes were PDT so only one search & replace, but obviously if you have other timezones, you would have to a separate search & replace for each.

You can use built-in map function:

result = map(lambda x: x * P, S)

or list comprehensions that is a bit more pythonic:

result = [x * P for x in S]

Using a dispatch_after block is in most cases better than using sleep(time) as the thread on which the sleep is performed is blocked from doing other work. when using dispatch_after the thread which is worked on does not get blocked so it can do other work in the meantime.
If you are working on the main thread of your application, using sleep(time) is bad for the user experience of your app as the UI is unresponsive during that time.

Dispatch after schedules the execution of a block of code instead of freezing the thread:

Swift = 3.0

let seconds = 4.0
DispatchQueue.main.asyncAfter(deadline: .now() + seconds) {
    // Put your code which should be executed with a delay here
}

Swift < 3.0

let time = dispatch_time(dispatch_time_t(DISPATCH_TIME_NOW), 4 * Int64(NSEC_PER_SEC))
dispatch_after(time, dispatch_get_main_queue()) {
    // Put your code which should be executed with a delay here
}

var map = {'myKey1':myObj1, 'mykey2':myObj2};
// You don't need any get function, just use
map['mykey1']

If you want to revert all changes AND be up-to-date with the current remote master (for example you find that the master HEAD has moved forward since you branched off it and your push is being 'rejected') you can use

git fetch  # will fetch the latest changes on the remote
git reset --hard origin/master # will set your local branch to match the representation of the remote just pulled down.

Yes, you could append ;Connection Timeout=30 to your connection string and specify the value you wish.

The timeout value set in the Connection Timeout property is a time expressed in seconds. If this property isn't set, the timeout value for the connection is the default value (15 seconds).

Moreover, setting the timeout value to 0, you are specifying that your attempt to connect waits an infinite time. As described in the documentation, this is something that you shouldn't set in your connection string:

A value of 0 indicates no limit, and should be avoided in a ConnectionString because an attempt to connect waits indefinitely.

Regardless of whether its a script, a html file (for a frame, for example), css file, image, whatever, if you dont specify a server/domain the path of the html doc will be the default, so you could do, for example,

<script type=text/javascript src='/dir/jsfile.js'></script>

or

<script type=text/javascript src='../../scripts/jsfile.js'></script>

If you don't provide the server/domain, the path will be relative to either the path of the page or script of the main document's path

<div id="412412412" class="input-group date">
     <div class="input-group-prepend">
          <button class="btn btn-danger" type="button">Button Click</button>
          <input type="text" class="form-control" value="">
      </div>
</div>

In my situation, i use this code:

$(this).parent().closest('.date').attr('id')

Hope this help someone.

Reporting to an external website/database

I wanted a way to simply and automatically report errors (since users often don't) from our applications. The easiest solution I could come up with was a public URL - a web page which could take input and store it to a database - that is sent data upon an application error. (The database could then be checked by a dev or a script to know if there are new errors.)

I wrote the web page in PHP and created a mysql database, user, and table to store the data. I decided on four user variables, an id, and a timestamp. The possible variables (either included in the URL or as POST data) are:

• app (application name)
• msg (message - e.g. Exception occurred ...)
• dev (developer - e.g. Pat)
• src (source - this would come from a variable pertaining to the machine on which the app was running, e.g. Environment.MachineName or some such)
• log (a log file or verbose message)

(All of the variables are optional, but nothing is reported if none of them are set - so if you just visit the website URL nothing is sent to the db.)

To send the data to the URL, I used NLog's WebService target. (Note, I had a few problems with this target at first. It wasn't until I looked at the source that I figured out that my url could not end with a /.)

All in all, it's not a bad system for keeping tabs on external apps. (Of course, the polite thing to do is to inform your users that you will be reporting possibly sensitive data and to give them a way to opt in/out.)

MySQL stuff

(The db user has only INSERT privileges on this one table in its own database.)

CREATE TABLE `reports` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `ts` timestamp NULL DEFAULT CURRENT_TIMESTAMP,
  `applicationName` text,
  `message` text,
  `developer` text,
  `source` text,
  `logData` longtext,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8 COMMENT='storage place for reports from external applications'

Website code

(PHP 5.3 or 5.2 with PDO enabled, file is index.php in /report folder)

<?php
$app = $_REQUEST['app'];
$msg = $_REQUEST['msg'];
$dev = $_REQUEST['dev'];
$src = $_REQUEST['src'];
$log = $_REQUEST['log'];

$dbData =
    array(  ':app' => $app,
            ':msg' => $msg,
            ':dev' => $dev,
            ':src' => $src,
            ':log' => $log
    );
//print_r($dbData); // For debugging only! This could allow XSS attacks.
if(isEmpty($dbData)) die("No data provided");

try {
$db = new PDO("mysql:host=$host;dbname=reporting", "reporter", $pass, array(
    PDO::ATTR_PERSISTENT => true
));
$s = $db->prepare("INSERT INTO reporting.reports 
    (
    applicationName, 
    message, 
    developer, 
    source, 
    logData
    )
    VALUES
    (
    :app, 
    :msg, 
    :dev, 
    :src, 
    :log
    );"
    );
$s->execute($dbData);
print "Added report to database";
} catch (PDOException $e) {
// Sensitive information can be displayed if this exception isn't handled
//print "Error!: " . $e->getMessage() . "<br/>";
die("PDO error");
}

function isEmpty($array = array()) {
    foreach ($array as $element) {
        if (!empty($element)) {
            return false;
        }
    }
    return true;

Note: there may be some issues with the size of the log file, but I haven't figured out a simple way to truncate it (e.g. a la *nix's tail command).

On Salesforce platform this error is caused by /, the solution is to escape these as //.

Here is another, very manual solution. You can define the size of the axis and paddings are considered accordingly (including legend and tickmarks). Hope it is of use to somebody.

Example (axes size are the same!):

   public class Temp {

        public static void main(String[] args) {

         File file = new File("c:/EventItemBroker.java");

         byte[] b = new byte[(int) file.length()];
         try {
               FileInputStream fileInputStream = new FileInputStream(file);
               fileInputStream.read(b);
               for (int i = 0; i < b.length; i++) {
                           System.out.print((char)b[i]);
                }
          } catch (FileNotFoundException e) {
                      System.out.println("File Not Found.");
                      e.printStackTrace();
          }
          catch (IOException e1) {
                   System.out.println("Error Reading The File.");
                    e1.printStackTrace();
          }

       }
    }

Converting Bytes to File

      public class WriteByteArrayToFile {

         public static void main(String[] args) {

            String strFilePath = "Your path";
            try {
                 FileOutputStream fos = new FileOutputStream(strFilePath);
                 String strContent = "Write File using Java ";

                 fos.write(strContent.getBytes());
                 fos.close();
           }
          catch(FileNotFoundException ex)   {
                 System.out.println("FileNotFoundException : " + ex);
          }
         catch(IOException ioe)  {
                 System.out.println("IOException : " + ioe);
          }

       }
     }

Some notes that I also found useful:

• Keep your default values on the right side.

  function whatever($var1, $var2, $var3="constant", $var4="another")
  

• The default value of the argument must be a constant expression. It can't be a variable or a function call.

You want to use String.Replace to remove a character.

s = s.Replace("\n", String.Empty);
s = s.Replace("\r", String.Empty);
s = s.Replace("\t", String.Empty);

Note that String.Trim(params char[] trimChars) only removes leading and trailing characters in trimChars from the instance invoked on.

You could make an extension method, which avoids the performance problems of the above of making lots of temporary strings:

static string RemoveChars(this string s, params char[] removeChars) {
    Contract.Requires<ArgumentNullException>(s != null);
    Contract.Requires<ArgumentNullException>(removeChars != null);
    var sb = new StringBuilder(s.Length);
    foreach(char c in s) { 
        if(!removeChars.Contains(c)) {
            sb.Append(c);
        }
    }
    return sb.ToString();
}

I built a library that can make any ViewPager, pagerAdapter (or FragmentStatePagerAdapter), and optional TabLayout infinitely Scrolling.

https://github.com/memorex386/infinite-scroll-viewpager-w-tabs

I had the same problem. This is my solution, I'm not sure that is the good practice, tell me if not:

state = {
  value: this.props.value
};

componentDidUpdate(prevProps) {
  if(prevProps.value !== this.props.value) {
    this.setState({value: this.props.value});
  }
}

UPD: Now you can do the same thing using React Hooks: (only if component is a function)

const [value, setValue] = useState(propName);
// This will launch only if propName value has chaged.
useEffect(() => { setValue(propName) }, [propName]);

This is really handy, but I wanted a way to show all user objects, not just tables, so I adapted it to use sys.objects instead of sys.tables

SET NOCOUNT ON
DECLARE @AllTables table (DbName sysname,SchemaName sysname, ObjectType char(2), ObjectName sysname)
DECLARE
     @SearchDb nvarchar(200)
    ,@SearchSchema nvarchar(200)
    ,@SearchObject nvarchar(200)
    ,@SQL nvarchar(4000)
SET @SearchDb='%'
SET @SearchSchema='%'
SET @SearchObject='%Something%'
SET @SQL='select ''?'' as DbName, s.name as SchemaName, t.type as ObjectType, t.name as ObjectName 
from [?].sys.objects t inner join sys.schemas s on t.schema_id=s.schema_id 
WHERE t.type in (''FN'',''IF'',''U'',''V'',''P'',''TF'') 
AND ''?'' LIKE '''+@SearchDb+''' 
AND s.name LIKE '''+@SearchSchema+''' 
AND t.name LIKE '''+@SearchObject+''''

INSERT INTO @AllTables (DbName, SchemaName, ObjectType, ObjectName)
    EXEC sp_msforeachdb @SQL
SET NOCOUNT OFF
SELECT * FROM @AllTables ORDER BY DbName, SchemaName, ObjectType, ObjectName

input:-webkit-autofill { background: #fff !important; }

If you are using an earlier version of QT (<5) try this

QMAKE_CXXFLAGS += -std=c++0x

You don't need jQuery for that. Use regular javascript

var arr = new Array();
// or var arr = [];
arr.push('value1');
arr.push('value2');

Note: In javascript, you can also use Objects as Arrays, but still have access to the Array prototypes. This makes the object behave like an array:

var obj = new Object();
Array.prototype.push.call(obj, 'value');

will create an object that looks like:

{
    0: 'value',
    length: 1
}

You can access the vaules just like a normal array f.ex obj[0].

In My case, I've written below code in build.gradle

android {
// ...
aaptOptions.cruncherEnabled = false
aaptOptions.useNewCruncher = false
// ...
}

It's work for me!...

You have a few options:

• Powershell looks for executables in your path, just as cmd.exe does. So you can just type explorer on the powershell prompt. Using this method, you can also pass cmd-line arguments (see http://support.microsoft.com/kb/314853)
• The Invoke-Item cmdlet provides a way to run an executable file or to open a file (or set of files) from within Windows PowerShell. Alias: ii
• use system.diagnostics.process

Examples:

PS C:\> explorer
PS C:\> explorer .
PS C:\> explorer /n
PS C:\> Invoke-Item c:\path\
PS C:\> ii c:\path\
PS C:\> Invoke-Item c:\windows\explorer.exe
PS C:\> ii c:\windows\explorer.exe
PS C:\> [diagnostics.process]::start("explorer.exe")

Have the certificate and bundle copied in one .crt file and make sure that there is a blank line between the certificates in the file.

This worked for me on a GitLab server after trying everything on the Internet.

First off, a disclaimer: I don't think marrying POST with URL parameters is a brilliant idea. Like others suggested, you're better off using a hidden form for passing user information.

However, a question made me curious how PHP is handling such a case. It turned out that it's possible in theory. Here's a proof:

post_url_params.html

<!DOCTYPE html>
<html>
    <head></head>
    <body>
        <form method="post" action="post_url_params.php?key1=value1">
            <input type="hidden" name="key2" value="value2">
            <input type="hidden" name="key3" value="value3">
            <input type="submit" value="click me">
        </form>
    </body>
</html>

post_url_params.php

<?php
    print_r($_POST);
    print_r($_GET);
    echo $_SERVER['REQUEST_METHOD'];
?>

Output

Array ( [key2] => value2 [key3] => value3 )
Array ( [key1] => value1 )
POST

One can clearly see that PHP stores URL parameters in the $_GET variable and form data in the $_POST variable. I suspect it's very PHP- and server-specific, though, and is definitely not a thing to rely on.

JSONP is a way of getting around the browser's same-origin policy. How? Like this:

The goal here is to make a request to otherdomain.com and alert the name in the response. Normally we'd make an AJAX request:

$.get('otherdomain.com', function (response) {
  var name = response.name;
  alert(name);
});

However, since the request is going out to a different domain, it won't work.

We can make the request using a <script> tag though. Both <script src="otherdomain.com"></script> and $.get('otherdomain.com') will result in the same request being made:

GET otherdomain.com

Q: But if we use the <script> tag, how could we access the response? We need to access it if we want to alert it.

A: Uh, we can't. But here's what we could do - define a function that uses the response, and then tell the server to respond with JavaScript that calls our function with the response as its argument.

Q: But what if the server won't do this for us, and is only willing to return JSON to us?

A: Then we won't be able to use it. JSONP requires the server to cooperate.

Q: Having to use a <script> tag is ugly.

A: Libraries like jQuery make it nicer. Ex:

$.ajax({
    url: "http://otherdomain.com",
    jsonp: "callback",
    dataType: "jsonp",
    success: function( response ) {
        console.log( response );
    }
});

It works by dynamically creating the <script> tag DOM element.

Q: <script> tags only make GET requests - what if we want to make a POST request?

A: Then JSONP won't work for us.

Q: That's ok, I just want to make a GET request. JSONP is awesome and I'm going to go use it - thanks!

A: Actually, it isn't that awesome. It's really just a hack. And it isn't the safest thing to use. Now that CORS is available, you should use it whenever possible.

Some important and successfully executed software projects like Google Chrome and Mozilla Firefox are fine examples of both iterative and incremental software development.

I will quote fine ars technica article which describes this approach: http://arstechnica.com/information-technology/2010/07/chrome-team-sets-six-week-cadence-for-new-major-versions/

According to Chrome program manager Anthony Laforge, the increased pace is designed to address three main goals. One is to get new features out to users faster. The second is make the release schedule predictable and therefore easier to plan which features will be included and which features will be targeted for later releases. Third, and most counterintuitive, is to cut the level of stress for Chrome developers. Laforge explains that the shorter, predictable time periods between releases are more like "trains leaving Grand Central Station." New features that are ready don't have to wait for others that are taking longer to complete—they can just hop on the current release "train." This can in turn take the pressure off developers to rush to get other features done, since another release train will be coming in six weeks. And they can rest easy knowing their work isn't holding the train from leaving the station.<<

The params parameter modifier gives callers a shortcut syntax for passing multiple arguments to a method. There are two ways to call a method with a params parameter:

1) Calling with an array of the parameter type, in which case the params keyword has no effect and the array is passed directly to the method:

object[] array = new[] { "1", "2" };

// Foo receives the 'array' argument directly.
Foo( array );

2) Or, calling with an extended list of arguments, in which case the compiler will automatically wrap the list of arguments in a temporary array and pass that to the method:

// Foo receives a temporary array containing the list of arguments.
Foo( "1", "2" );

// This is equivalent to:
object[] temp = new[] { "1", "2" );
Foo( temp );

In order to pass in an object array to a method with a "params object[]" parameter, you can either:

1) Create a wrapper array manually and pass that directly to the method, as mentioned by lassevk:

Foo( new object[] { array } );  // Equivalent to calling convention 1.

2) Or, cast the argument to object, as mentioned by Adam, in which case the compiler will create the wrapper array for you:

Foo( (object)array );  // Equivalent to calling convention 2.

However, if the goal of the method is to process multiple object arrays, it may be easier to declare it with an explicit "params object[][]" parameter. This would allow you to pass multiple arrays as arguments:

void Foo( params object[][] arrays ) {
  foreach( object[] array in arrays ) {
    // process array
  }
}

...
Foo( new[] { "1", "2" }, new[] { "3", "4" } );

// Equivalent to:
object[][] arrays = new[] {
  new[] { "1", "2" },
  new[] { "3", "4" }
};
Foo( arrays );

Edit: Raymond Chen describes this behavior and how it relates to the C# specification in a new post.

You can put iframe inside a <div>

<div>
    <iframe></iframe>
</div>

It works because it is now inside a block element.

Stacker posed a great answer, I would go one step farther to make it more dynamic and use Spring 3 EL Expression.

<bean id="listBean" class="java.util.ArrayList">
        <constructor-arg>
            <value>#{springDAOBean.getGenericListFoo()}</value>
        </constructor-arg>
</bean>

I was trying to figure out how I could do this with the util:list but couldn't get it work due to conversion errors.

If you want the max for array or list indices (equivalent to size_t in C/C++), you can use numpy:

np.iinfo(np.intp).max

This is same as sys.maxsize however advantage is that you don't need import sys just for this.

If you want max for native int on the machine:

np.iinfo(np.intc).max

You can look at other available types in doc.

For floats you can also use sys.float_info.max.

As we've already figured out in the question and the posted answers, there is an anti Web-scraping and a Bot detection service called "Distil Networks" in play here. And, according to the company CEO's interview:

Even though they can create new bots, we figured out a way to identify Selenium the a tool they’re using, so we’re blocking Selenium no matter how many times they iterate on that bot. We’re doing that now with Python and a lot of different technologies. Once we see a pattern emerge from one type of bot, then we work to reverse engineer the technology they use and identify it as malicious.

It'll take time and additional challenges to understand how exactly they are detecting Selenium, but what can we say for sure at the moment:

• it's not related to the actions you take with selenium - once you navigate to the site, you get immediately detected and banned. I've tried to add artificial random delays between actions, take a pause after the page is loaded - nothing helped
• it's not about browser fingerprint either - tried it in multiple browsers with clean profiles and not, incognito modes - nothing helped
• since, according to the hint in the interview, this was "reverse engineering", I suspect this is done with some JS code being executed in the browser revealing that this is a browser automated via selenium webdriver

Decided to post it as an answer, since clearly:

Can a website detect when you are using selenium with chromedriver?

Yes.

Also, what I haven't experimented with is older selenium and older browser versions - in theory, there could be something implemented/added to selenium at a certain point that Distil Networks bot detector currently relies on. Then, if this is the case, we might detect (yeah, let's detect the detector) at what point/version a relevant change was made, look into changelog and changesets and, may be, this could give us more information on where to look and what is it they use to detect a webdriver-powered browser. It's just a theory that needs to be tested.

What you are doing is not necessarily bad practice but it does however require an extraordinary amount of typing. I would accomplish what you are trying to do like this.

foreach($_POST as $var => $val){
    $$var = $val;
}

This will take all the POST variables and put them in their own individual variables. So if you have a input field named email and the luser puts in [email protected] you will have a var named $email with a value of "[email protected]".

Remember - if you set the buttons to vbOkOnly - it will always return 1.

So you can't decide if a user clicked on the close or the OK button. You just have to add a vbOk option.

std::pair<int, int> divide(int dividend, int divisor)
{
   // :
   return std::make_pair(quotient, remainder);
}

std::pair<int, int> answer = divide(5,2);
 // answer.first == quotient
 // answer.second == remainder

std::pair is essentially your struct solution, but already defined for you, and ready to adapt to any two data types.

0xe0434352 is the SEH code for a CLR exception. If you don't understand what that means, stop and read A Crash Course on the Depths of Win32™ Structured Exception Handling. So your process is not handling a CLR exception. Don't shoot the messenger, KERNELBASE.DLL is just the unfortunate victim. The perpetrator is MyApp.exe.

There should be a minidump of the crash in DrWatson folders with a full stack, it will contain everything you need to root cause the issue.

I suggest you wire up, in your myapp.exe code, AppDomain.UnhandledException and Application.ThreadException, as appropriate.

Just came to this post from a google search on how to check if a string equals another string.

I use HandlebarsJS in NodeJS server-side, but I also use the same template files on the front-end using the browser version of HandlebarsJS to parse it. This meant that if I wanted a custom helper, I'd have to define it in 2 separate places, or assign a function to the object in question - too much effort!!

What people forget is that certain objects have inherit functions that can be used in the moustache template. In the case of a string:

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/match

An Array containing the entire match result and any parentheses-captured matched results; null if there were no matches.

We can use this method to return either an array of matches, or null if no matches were found. This is perfect, because looking at the HandlebarsJS documentation http://handlebarsjs.com/builtin_helpers.html

You can use the if helper to conditionally render a block. If its argument returns false, undefined, null, "", 0, or [], Handlebars will not render the block.

So...

{{#if your_string.match "what_youre_looking_for"}} 
String found :)
{{else}}
No match found :(
{{/if}}

UPDATE:

After testing on all browsers, this doesn't work on Firefox. HandlebarsJS passes other arguments to a function call, meaning that when String.prototype.match is called, the second argument (i.e. the Regexp flags for the match function call as per above documentation) appears to be being passed. Firefox sees this as a deprecated use of String.prototype.match, and so breaks.

A workaround is to declare a new functional prototype for the String JS object, and use that instead:

if(typeof String.includes !== 'function') {
    String.prototype.includes = function(str) {
        if(!(str instanceof RegExp))
            str = new RegExp((str+'').escapeRegExp(),'g');
        return str.test(this);
    }
}

Ensure this JS code is included before you run your Handlebars.compile() function, then in your template...

{{#your_string}}
    {{#if (includes "what_youre_looking_for")}} 
        String found :)
    {{else}}
        No match found :(
    {{/if}}
{{/your_string}}

If you have deadlocks occurring in a combination of locks, threads and forks in the logging module, that is reported in bug report 6721 (see also related SO question).

There is a small fixup solution posted here.

However, that will just fix any potential deadlocks in logging. That will not fix that things are maybe garbled up. See the other answers presented here.

The following event listener solved this nicely for me even when using multiple markers and info windows:

//Add click event listener
google.maps.event.addListener(marker, 'click', function() {
  // Helper to check if the info window is already open
  google.maps.InfoWindow.prototype.isOpen = function(){
      var map = infoWindow.getMap();
      return (map !== null && typeof map !== "undefined");
  }
  // Do the check
  if (infoWindow.isOpen()){
    // Close the info window
    infoWindow.close();
  } else {
    //Set the new content
    infoWindow.setContent(contentString);
    //Open the infowindow
    infoWindow.open(map, marker);
  }
});

set myPATH="C:\Users\DEB\Downloads\10.1.1.0.4"
cd %myPATH%

• The single quotes do not indicate a string, they make it starts: 'C:\ instead of C:\ so

• %name% is the usual syntax for expanding a variable, the !name! syntax needs to be enabled using the command setlocal ENABLEDELAYEDEXPANSION first, or by running the command prompt with CMD /V:ON.

• Don't use PATH as your name, it is a system name that contains all the locations of executable programs. If you overwrite it, random bits of your script will stop working. If you intend to change it, you need to do set PATH=%PATH%;C:\Users\DEB\Downloads\10.1.1.0.4 to keep the current PATH content, and add something to the end.

From Effective Go:

Constants in Go are just that—constant. They are created at compile time, even when defined as locals in functions, and can only be numbers, characters (runes), strings or booleans. Because of the compile-time restriction, the expressions that define them must be constant expressions, evaluatable by the compiler. For instance, 1<<3 is a constant expression, while math.Sin(math.Pi/4) is not because the function call to math.Sin needs to happen at run time.

Slices and arrays are always evaluated during runtime:

var TestSlice = []float32 {.03, .02}
var TestArray = [2]float32 {.03, .02}
var TestArray2 = [...]float32 {.03, .02}

[...] tells the compiler to figure out the length of the array itself. Slices wrap arrays and are easier to work with in most cases. Instead of using constants, just make the variables unaccessible to other packages by using a lower case first letter:

var ThisIsPublic = [2]float32 {.03, .02}
var thisIsPrivate = [2]float32 {.03, .02}

thisIsPrivate is available only in the package it is defined. If you need read access from outside, you can write a simple getter function (see Getters in golang).

I had this annoying issue since I upgraded my VS 2019 to 16.4.3 and caused me a lot of headache.
Finally I solved the problem this way:

1. Stop Debugging
2. Select the solution from "Solution Explorer"
3. In the Properties window change the "Active config" Property From "Release|Any CPU" To "Debug|Any CPU"
4. In Debug > Options > General Check the Edit and Continue checkbox

That worked for me, and hope it works for you too.

UPDATE

cleanBuildCache no longer works.

Android Gradle plugin now utilizes Gradle cache feature
https://guides.gradle.org/using-build-cache/

TO CLEAR CACHE

Clean the cache directory to avoid any hits from previous builds

 rm -rf $GRADLE_HOME/caches/build-cache-*

https://guides.gradle.org/using-build-cache/#caching_android_projects

Other digressions: see here (including edits).

=== OBSOLETE INFO ===

Newest solution using Gradle task:

cleanBuildCache

Available via Android plugin for Gradle, revision 2.3.0 (February 2017)

Dependencies:

1. Gradle 3.3 or higher.
2. Build Tools 25.0.0 or higher.

More info at:
https://developer.android.com/studio/build/build-cache.html#clear_the_build_cache

Background

Build cache
Stores certain outputs that the Android plugin generates when building your project (such as unpackaged AARs and pre-dexed remote dependencies). Your clean builds are much faster while using the cache because the build system can simply reuse those cached files during subsequent builds, instead of recreating them. Projects using Android plugin 2.3.0 and higher use the build cache by default. To learn more, read Improve Build Speed with Build Cache.

NOTE: The cleanBuildCache task is not available if you disable the build cache.

USAGE

Windows:

gradlew cleanBuildCache

Linux / Mac:

gradle cleanBuildCache

Android Studio / IntelliJ:

gradle tab (default on right) select and run the task or add it via the configuration window 

NOTE: gradle / gradlew are system specific files containing scripts. Please see the related system info how to execute the scripts:

• Linux
• Windows
• Mac

To remove the border-radius on the corners add this style to your custom.css file

    .navbar-inner{
       -webkit-border-radius: 0; -moz-border-radius: 0; border-radius: 0;
    }

TEXT is a data-type for text based input. On the other hand, you have BLOB and CLOB which are more suitable for data storage (images, etc) due to their larger capacity limits (4GB for example).

As for the difference between BLOB and CLOB, I believe CLOB has character encoding associated with it, which implies it can be suited well for very large amounts of text.

BLOB and CLOB data can take a long time to retrieve, relative to how quick data from a TEXT field can be retrieved. So, use only what you need.

I had similar problem, but the wrong setting was in the extern .lib file from which I did not have sources. If you do not have the source files, the simplest workaround is to just change the content of the .lib file.

Open the .lib file in an editor (I used PSPad, bud Windows notepad is also possible) and replace all occurences of _ITERATOR_DEBUG_LEVEL=2 to _ITERATOR_DEBUG_LEVEL=0

You will have to use the fluent API to do this.

Try adding the following to your DbContext:

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{   
    modelBuilder.Entity<User>()
        .HasOptional(a => a.UserDetail)
        .WithOptionalDependent()
        .WillCascadeOnDelete(true);
}

This worked for me Option + left-arrow or Option + right-arrow for moving the cursor to the start or end of the line.

Mac Os Version: Catalina

From MSDN:

The foreach statement repeats a group of embedded statements for each element in an array or an object collection that implements the System.Collections.IEnumerable or System.Collections.Generic.IEnumerable(Of T) interface.

So, it's not necessarily Array. It could even be a lazy collection with no idea about the count of items in the collection.

It may not be the elegant way but you can iterate all classes in the assembly and invoke Type.IsSubclassOf(AbstractDataExport) for each one.

Regex to the rescue!

import re

s = re.sub('[^0-9a-zA-Z]+', '*', s)

Example:

>>> re.sub('[^0-9a-zA-Z]+', '*', 'h^&ell`.,|o w]{+orld')
'h*ell*o*w*orld'

Use the <sup></sup>tag (<sub></sub> is the equivalent for subscripts). See this gist for an example.

You can just write your chars as Strings and use the equals method.

For Example:

String firstChar = "A";
String secondChar = "B";
String thirdChar = "C";

if (firstChar.equalsIgnoreCase(secondChar) ||
        (firstChar.equalsIgnoreCase(thirdChar))) // As many equals as you want
{
    System.out.println(firstChar + " is the same as " + secondChar);
} else {
    System.out.println(firstChar + " is different than " + secondChar);
}

Use $ne (for "not equal")

db.collection.find({ "fieldToCheck": { $exists: true, $ne: null } })

I would put this as a comment, but I don't have the rep for it. What Josh Crozier answered is correct, but for IE .cur and .ani are the only supported formats for this. So you should probably have a fallback just in case:

.test {
    cursor:url("http://www.javascriptkit.com/dhtmltutors/cursor-hand.gif"), url(foo.cur), auto;
}

Here is a working example (you'll have to trust me that there's a submit() method on the controller - it prints an Object, like {user: 'abc'} if 'abc' is entered in the input field):

<form #loginForm="ngForm" (ngSubmit)="submit(loginForm.value)">
    <input type="text" name="user" ngModel required>
    <button  type="submit"  [disabled]="loginForm.invalid">
        Submit
    </button>
</form>

As you can see:

• don't use loginForm.form, just use loginForm
• loginForm.invalid works as well as !loginForm.valid
• if you want submit() to be passed the correct value(s), the input element should have name and ngModel attributes

Also, this is when you're NOT using the new FormBuilder, which I recommend. Things are very different when using FormBuilder.

This was already mentioned in a comment by benvoliot above. But, I think it's worth a top-level post because it sure had me scratching my head. I'm posting this in case it helps someone else out.

I wrote a simple test client and the CoreConnectionPNames.CONNECTION_TIMEOUT timeout works perfectly in that case. The request gets canceled if the server doesn't respond.

Inside the server code I was actually trying to test however, the identical code never times out.

Changing it to time out on the socket connection activity (CoreConnectionPNames.SO_TIMEOUT) rather than the HTTP connection (CoreConnectionPNames.CONNECTION_TIMEOUT) fixed the problem for me.

Also, read the Apache docs carefully: http://hc.apache.org/httpcomponents-core-ga/httpcore/apidocs/org/apache/http/params/CoreConnectionPNames.html#CONNECTION_TIMEOUT

Note the bit that says

Please note this parameter can only be applied to connections that are bound to a particular local address.

I hope that saves someone else all the head scratching I went through. That will teach me not to read the documentation thoroughly!

The Heap is divided into young and old generations as follows :

Young Generation: It is a place where an object lived for a short period and it is divided into two spaces:

• Eden Space: When object created using new keyword memory allocated on this space.
• Survivor Space (S0 and S1): This is the pool which contains objects which have survived after minor java garbage collection from Eden space.

Old Generation: This pool basically contains tenured and virtual (reserved) space and will be holding those objects which survived after garbage collection from the Young Generation.

• Tenured Space: This memory pool contains objects which survived after multiple garbage collection means an object which survived after garbage collection from Survivor space.

Explanation

Let's imagine our application has just started.

So at this point all three of these spaces are empty (Eden, S0, S1).

Whenever a new object is created it is placed in the Eden space.

When the Eden space gets full then the garbage collection process (minor GC) will take place on the Eden space and any surviving objects are moved into S0.

Our application then continues running add new objects are created in the Eden space the next time that the garbage collection process runs it looks at everything in the Eden space and in S0 and any objects that survive get moved into S1.

PS: Based on the configuration that how much time object should survive in Survivor space, the object may also move back and forth to S0 and S1 and then reaching the threshold objects will be moved to old generation heap space.

May it will help for u. U should use (localdb).

LocalDB automatic instance

Server=(localdb)\v11.0;Integrated Security=true;

LocalDB automatic instance with specific data file

Server=(localdb)\v11.0;Integrated Security=true; AttachDbFileName=C:\MyFolder\MyData.mdf;

Those steps should be able to be shortened down to:

hg pull
hg update -r MY_BRANCH -C

The -C flag tells the update command to discard all local changes before updating.

However, this might still leave untracked files in your repository. It sounds like you want to get rid of those as well, so I would use the purge extension for that:

hg pull
hg update -r MY_BRANCH -C
hg purge

In any case, there is no single one command you can ask Mercurial to perform that will do everything you want here, except if you change the process to that "full clone" method that you say you can't do.

I've got one more additional option to get value by id:

var idElement = document.getElementById("idName");
var selectedValue = idElement.options[idElement.selectedIndex].value;

It's a simple JavaScript solution.

git pull is nothing but git fetch followed by git merge. So what you can do is

git fetch remote example_branch

git merge <commit_hash>

After doing all of above I still couldn't login as root remotely, but Telnetting to port 3306 confirmed that MySQL was accepting connections.

I started looking at the users in MySQL and noticed there were multiple root users with different passwords.

select user, host, password from mysql.user;

So in MySQL I set all the passwords for root again and I could finally log in remotely as root.

use mysql;
update user set password=PASSWORD('NEWPASSWORD') where User='root';
flush privileges;

Since favorites is an array, you just need to splice it off and save the document.

var mongoose = require('mongoose'),
    Schema = mongoose.Schema;

var favorite = new Schema({
    cn: String,
    favorites: Array
});

module.exports = mongoose.model('Favorite', favorite);

exports.deleteFavorite = function (req, res, next) {
    if (req.params.callback !== null) {
        res.contentType = 'application/javascript';
    }
    // Changed to findOne instead of find to get a single document with the favorites.
    Favorite.findOne({cn: req.params.name}, function (error, doc) {
        if (error) {
            res.send(null, 500);
        } else if (doc) {
            var records = {'records': doc};
            // find the delete uid in the favorites array
            var idx = doc.favorites ? doc.favorites.indexOf(req.params.deleteUid) : -1;
            // is it valid?
            if (idx !== -1) {
                // remove it from the array.
                doc.favorites.splice(idx, 1);
                // save the doc
                doc.save(function(error) {
                    if (error) {
                        console.log(error);
                        res.send(null, 500);
                    } else {
                        // send the records
                        res.send(records);
                    }
                });
                // stop here, otherwise 404
                return;
            }
        }
        // send 404 not found
        res.send(null, 404);
    });
};

One of the problems of doing automated testing for APIs is that many of the tools require you to have the API server up and running before you run your test suite. It can be a real advantage to have a unit testing framework that is capable of running and querying the APIs in a fully automated test environment.

An option that's good for APIs implemented with Node.JS / Express is to use mocha for automated testing. In addition to unit tests, its easy to write functional tests against the APIs, separated into different test suites. You can start up the API server automatically in the local test environment and set up a local test database. Using make, npm, and a build server, you can create a "make test" target and an incremental build that will run the entire test suite every time a piece of code is submitted to your repository. For the truly fastidious developer, it will even generate a nice HTML code-coverage report showing you which parts of your code base are covered by tests or not. If this sounds interesting, here's a blog post that provides all the technical details.

If you're not using node, then whatever the defacto unit testing framework for the language is (jUnit, cucumber/capybara, etc) - look at its support for spinning up servers in the local test environment and running the HTTP queries. If it's a large project, the effort to get automated API testing and continual integration working will pay off pretty quickly.

Hope that helps.

Very informative answer from @stej, but here is a short answer: Among other options, you have 3 simple options to format [System.DateTime] stored in a variable:

1. Pass the variable to the Get-Date cmdlet: Get-Date -Format "HH:mm" $date

2. Use toString() method: $date.ToString("HH:mm")

3. Use Composite formatting: "{0:HH:mm}" -f $date

One more variant is using very powerfull JOOR library https://github.com/jOOQ/jOOR

MyObject myObject = new MyObject()
on(myObject).get("privateField");  

It allows to modify any fields like final static constants and call yne protected methods without specifying concrete class in the inheritance hierarhy

You are right that it should work; perhaps you forgot to instantiate something. Does your code look something like this?

String rssFeedURL = "http://stackoverflow.com";
this.rssFeedURLS = new ArrayList<String>();
this.rssFeedURLS.add(rssFeedURL);
if(this.rssFeedURLs.contains(rssFeedURL)) {
// this code will execute
}

For reference, note that the following conditional will also execute if you append this code to the above:

String copyURL = new String(rssFeedURL);
if(this.rssFeedURLs.contains(copyURL)) {
// code will still execute because contains() checks equals()
}

Even though (rssFeedURL == copyURL) is false, rssFeedURL.equals(copyURL) is true. The contains method cares about the equals method.

You can use jquery.form.js plugin to upload image via ajax to the server.

http://malsup.com/jquery/form/

Here is the sample jQuery ajax image upload script

(function() {
$('form').ajaxForm({
    beforeSubmit: function() {  
        //do validation here


    },

    beforeSend:function(){
       $('#loader').show();
       $('#image_upload').hide();
    },
    success: function(msg) {

        ///on success do some here
    }
}); })();  

If you have any doubt, please refer following ajax image upload tutorial here

To multiply, use mult for signed multiplication and multu for unsigned multiplication. Note that the result of the multiplication of two 32-bit numbers yields a 64-number. If you want the result back in $v0 that means that you assume the result will fit in 32 bits.

The 32 most significant bits will be held in the HI special register (accessible by mfhi instruction) and the 32 least significant bits will be held in the LO special register (accessible by the mflo instruction):

E.g.:

li $a0, 5
li $a1, 3
mult $a0, $a1
mfhi $a2 # 32 most significant bits of multiplication to $a2
mflo $v0 # 32 least significant bits of multiplication to $v0

To divide, use div for signed division and divu for unsigned division. In this case, the HI special register will hold the remainder and the LO special register will hold the quotient of the division.

E.g.:

div $a0, $a1
mfhi $a2 # remainder to $a2
mflo $v0 # quotient to $v0

I like the answers setting border-top, but they are somehow still a little off in Chrome...
BUT if I set border-top: 1px solid black; and border-bottom: 0px; I end up with a truly single line (that also works fine with higher thickness).

In order to calculate the difference you have to put the + operator,

that way typescript converts the dates to numbers.

+new Date()- +new Date("2013-02-20T12:01:04.753Z")

From there you can make a formula to convert the difference to minutes or hours.

Joining the party late, but just as a complement, I ran into some problems with Seaborn not so long ago, because CoLab installed a version with !pip that wasn't updated. In my specific case, I couldn't use Scatterplot, for example. The answer to this is below:

To install the module, all you need is:

!pip install seaborn

To upgrade it to the most updated version:

!pip install --upgrade seaborn

If you want to install a specific version

!pip install seaborn==0.9.0

I believe all the rules common to pip apply normally, so that pretty much should work.

You can get the comments of a particular method by using the ReflectionMethod class and calling ->getDocComment().

http://www.php.net/manual/en/reflectionclass.getdoccomment.php

If you want to add some comments in your JSON and allow trailing commas you might want use below implemention:

var fs = require('fs');

var data = parseJsData('./message.json');

console.log('[INFO] data:', data);

function parseJsData(filename) {
    var json = fs.readFileSync(filename, 'utf8')
        .replace(/\s*\/\/.+/g, '')
        .replace(/,(\s*\})/g, '}')
    ;
    return JSON.parse(json);
}

Note that it might not work well if you have something like "abc": "foo // bar" in your JSON. So YMMV.

I added this on my project and it seems to work:

HTMLElement.prototype.prependHtml = function (element) {
    const div = document.createElement('div');
    div.innerHTML = element;
    this.insertBefore(div, this.firstChild);
};

HTMLElement.prototype.appendHtml = function (element) {
    const div = document.createElement('div');
    div.innerHTML = element;
    while (div.children.length > 0) {
        this.appendChild(div.children[0]);
    }
};

Example:

document.body.prependHtml(`<a href="#">Hello World</a>`);
document.body.appendHtml(`<a href="#">Hello World</a>`);

Problem seems that you are not handling GET requests appropriately or directly posting the data without first getting the form.

When you first access the page, client will send GET request, in that case you should send html with appropriate form.

Later, user fills up the form and sends POST request with form data.

Your view should be:

def deposit(request,account_num):
   if request.method == 'POST':
      form_=AccountForm(request.POST or None, instance=account)
      if form.is_valid(): 
          #handle form data
          return HttpResponseRedirect("/history/" + account_num + "/")
      else:
         #handle when form not valid
    else:
       #handle when request is GET (or not POST)
       form_=AccountForm(instance=account)

    return render_to_response('history.html',
                          {'account_form': form},
                          context_instance=RequestContext(request))

Consider:

Function GetFolder() As String
    Dim fldr As FileDialog
    Dim sItem As String
    Set fldr = Application.FileDialog(msoFileDialogFolderPicker)
    With fldr
        .Title = "Select a Folder"
        .AllowMultiSelect = False
        .InitialFileName = Application.DefaultFilePath
        If .Show <> -1 Then GoTo NextCode
        sItem = .SelectedItems(1)
    End With
NextCode:
    GetFolder = sItem
    Set fldr = Nothing
End Function

By now, cloud bitbucket (I'm not sure which version) allows to revert a commit from the file system as follows (I do not see how to revert from the Bitbucket interface in the Chrome browser).

-backup your entire directory to secure the changes you inadvertently committed

-select checked out directory

-right mouse button: tortoise git menu

-repo-browser (the menu option 'revert' only undoes the uncommited changes)

-press the HEAD button

-select the uppermost line (the last commit)

-right mouse button: revert change by this commit

-after it undid the changes on the file system, press commit

-this updates GIT with a message 'Revert (your previous message). This reverts commit so-and-so'

-select 'commit and push'.

Starting with Requests version 2.4.2, you can use the json= parameter (which takes a dictionary) instead of data= (which takes a string) in the call:

>>> import requests
>>> r = requests.post('http://httpbin.org/post', json={"key": "value"})
>>> r.status_code
200
>>> r.json()
{'args': {},
 'data': '{"key": "value"}',
 'files': {},
 'form': {},
 'headers': {'Accept': '*/*',
             'Accept-Encoding': 'gzip, deflate',
             'Connection': 'close',
             'Content-Length': '16',
             'Content-Type': 'application/json',

I've tried this in Python 3.6.9

Convert Binary to Decimal

>>> 0b101111
47

>>> int('101111',2)
47

Convert Decimal to binary

>>> bin(47)
'0b101111'

Place a 0 as the second parameter python assumes it as decimal.

>>> int('101111',0)
101111

Interestingly, when I replaced this:

$("body").trigger("click")

With this:

jQuery("body").trigger("click")

It works!

Two ways to read file into list in python (note these are not either or) -

1. use of with - supported from python 2.5 and above
2. use of list comprehensions

1. use of with

This is the pythonic way of opening and reading files.

#Sample 1 - elucidating each step but not memory efficient
lines = []
with open("C:\name\MyDocuments\numbers") as file:
    for line in file: 
        line = line.strip() #or some other preprocessing
        lines.append(line) #storing everything in memory!

#Sample 2 - a more pythonic and idiomatic way but still not memory efficient
with open("C:\name\MyDocuments\numbers") as file:
    lines = [line.strip() for line in file]

#Sample 3 - a more pythonic way with efficient memory usage. Proper usage of with and file iterators. 
with open("C:\name\MyDocuments\numbers") as file:
    for line in file:
        line = line.strip() #preprocess line
        doSomethingWithThisLine(line) #take action on line instead of storing in a list. more memory efficient at the cost of execution speed.

the .strip() is used for each line of the file to remove \n newline character that each line might have. When the with ends, the file will be closed automatically for you. This is true even if an exception is raised inside of it.

2. use of list comprehension

This could be considered inefficient as the file descriptor might not be closed immediately. Could be a potential issue when this is called inside a function opening thousands of files.

data = [line.strip() for line in open("C:/name/MyDocuments/numbers", 'r')]

Note that file closing is implementation dependent. Normally unused variables are garbage collected by python interpreter. In cPython (the regular interpreter version from python.org), it will happen immediately, since its garbage collector works by reference counting. In another interpreter, like Jython or Iron Python, there may be a delay.

Do you need to install it with yum? There's plenty other possibilities:

• Grab the binary from http://maven.apache.org/download.html and put it in your /usr/bn
• If you are using Eclipse you can get the m2eclipse plugin (http://m2eclipse.sonatype.org/) which bundles a version of maven

If you are using PHP's curl bindings, you can check the error code using curl_getinfo as such:

$handle = curl_init($url);
curl_setopt($handle,  CURLOPT_RETURNTRANSFER, TRUE);

/* Get the HTML or whatever is linked in $url. */
$response = curl_exec($handle);

/* Check for 404 (file not found). */
$httpCode = curl_getinfo($handle, CURLINFO_HTTP_CODE);
if($httpCode == 404) {
    /* Handle 404 here. */
}

curl_close($handle);

/* Handle $response here. */

Just treat the ES6 class name the same as you would have treated the constructor name in the ES5 way. They are one and the same.

The ES6 syntax is just syntactic sugar and creates exactly the same underlying prototype, constructor function and objects.

So, in your ES6 example with:

// animal.js
class Animal {
    ...
}

var a = new Animal();

module.exports = {Animal: Animal};

You can just treat Animal like the constructor of your object (the same as you would have done in ES5). You can export the constructor. You can call the constructor with new Animal(). Everything is the same for using it. Only the declaration syntax is different. There's even still an Animal.prototype that has all your methods on it. The ES6 way really does create the same coding result, just with fancier/nicer syntax.

On the import side, this would then be used like this:

const Animal = require('./animal.js').Animal;

let a = new Animal();

This scheme exports the Animal constructor as the .Animal property which allows you to export more than one thing from that module.

If you don't need to export more than one thing, you can do this:

// animal.js
class Animal {
    ...
}

module.exports = Animal;

And, then import it with:

const Animal = require('./animal.js');

let a = new Animal();

List<Address> addList=new ArrayList<Address>();


@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
@Column(name="emp_id")
public int getId() {
    return id;
}
public void setId(int id) {
    this.id = id;
}
public String getEmpName() {
    return empName;
}
public void setEmpName(String empName) {
    this.empName = empName;
}

@OneToMany(mappedBy="employee",cascade=CascadeType.ALL)
public List<Address> getAddList() {
    return addList;
}

public void setAddList(List<Address> addList) {
    this.addList = addList;
}
}

We have two entities Employee and Address with One to Many relationship.

import java.io.Serializable;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.ManyToOne;
import javax.persistence.Table;

@Entity
@Table(name="address")
public class Address implements Serializable{

private static final long serialVersionUID = 1L;

private int address_id;
private String address;
Employee employee;

@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
public int getAddress_id() {
    return address_id;
}
public void setAddress_id(int address_id) {
    this.address_id = address_id;
}
public String getAddress() {
    return address;
}
public void setAddress(String address) {
    this.address = address;
}

@ManyToOne
@JoinColumn(name="emp_id")
public Employee getEmployee() {
    return employee;
}
public void setEmployee(Employee employee) {
    this.employee = employee;
}
}

By this way we can implement inner join between two tables

import java.util.List;
import org.hibernate.Query;
import org.hibernate.Session;

public class Main {

public static void main(String[] args) {
    saveEmployee();

    retrieveEmployee();

}

private static void saveEmployee() {
    Employee employee=new Employee();
    Employee employee1=new Employee();
    Employee employee2=new Employee();
    Employee employee3=new Employee();

    Address address=new Address();
    Address address1=new Address();
    Address address2=new Address();
    Address address3=new Address();

    address.setAddress("1485,Sector 42 b");
    address1.setAddress("1485,Sector 42 c");
    address2.setAddress("1485,Sector 42 d");
    address3.setAddress("1485,Sector 42 a");

    employee.setEmpName("Varun");
    employee1.setEmpName("Krishan");
    employee2.setEmpName("Aasif");
    employee3.setEmpName("Dut");

    address.setEmployee(employee);
    address1.setEmployee(employee1);
    address2.setEmployee(employee2);
    address3.setEmployee(employee3);

    employee.getAddList().add(address);
    employee1.getAddList().add(address1);
    employee2.getAddList().add(address2);
    employee3.getAddList().add(address3);

    Session session=HibernateUtil.getSessionFactory().openSession();

    session.beginTransaction();

    session.save(employee);
    session.save(employee1);
    session.save(employee2);
    session.save(employee3);
    session.getTransaction().commit();
    session.close();
}

private static void retrieveEmployee() {
    try{

    String sqlQuery="select e from Employee e inner join e.addList";

    Session session=HibernateUtil.getSessionFactory().openSession();

    Query query=session.createQuery(sqlQuery);

    List<Employee> list=query.list();

     list.stream().forEach((p)->{System.out.println(p.getEmpName());});     
    session.close();
    }catch(Exception e){
        e.printStackTrace();
    }
}
}

I have used Java 8 for loop for priting the names. Make sure you have jdk 1.8 with tomcat 8. Also add some more records for better understanding.

 public class HibernateUtil {
 private static SessionFactory sessionFactory ;
 static {
    Configuration configuration = new Configuration();

    configuration.addAnnotatedClass(Employee.class);
    configuration.addAnnotatedClass(Address.class);
                  configuration.setProperty("connection.driver_class","com.mysql.jdbc.Driver");
    configuration.setProperty("hibernate.connection.url", "jdbc:mysql://localhost:3306/hibernate");                                
    configuration.setProperty("hibernate.connection.username", "root");     
    configuration.setProperty("hibernate.connection.password", "root");
    configuration.setProperty("dialect", "org.hibernate.dialect.MySQLDialect");
    configuration.setProperty("hibernate.hbm2ddl.auto", "update");
    configuration.setProperty("hibernate.show_sql", "true");
    configuration.setProperty(" hibernate.connection.pool_size", "10");


   // configuration
    StandardServiceRegistryBuilder builder = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties());
    sessionFactory = configuration.buildSessionFactory(builder.build());
 }
public static SessionFactory getSessionFactory() {
    return sessionFactory;
}
} 

Given a regular expression of (foobar) you can reference the first group using $1 and so on if you have more groups in the replace input field.

You cannot color plain text in a GitHub README.md file. You can however add color to code samples with the tags below.

To do this just add tags such as these samples to your README.md file:

```json
   // code for coloring
```
```html
   // code for coloring
```
```js
   // code for coloring
```
```css
   // code for coloring
```
// etc.

No "pre" or "code" tags needed.

This is covered in the GitHub Markdown documentation (about half way down the page, there's an example using Ruby). GitHub uses Linguist to identify and highlight syntax - you can find a full list of supported languages (as well as their markdown keywords) over in the Linguist's YAML file.

The variable arguments must be the last of the parameters specified in your function declaration. If you try to specify another parameter after the variable arguments, the compiler will complain since there is no way to determine how many of the parameters actually belong to the variable argument.

void print(final String format, final String... arguments) {
    System.out.format( format, arguments );
}

Use the ampersand just like you would from the shell.

#!/usr/bin/bash
function_to_fork() {
   ...
}

function_to_fork &
# ... execution continues in parent process ...

I would use the back-tick ``.

let name1 = 'Geoffrey';
let msg1 = `Hello ${name1}`;
console.log(msg1); // 'Hello Geoffrey'

But if you don't know name1 when you create msg1.

For exemple if msg1 came from an API.

You can use :

let name2 = 'Geoffrey';
let msg2 = 'Hello ${name2}';
console.log(msg2); // 'Hello ${name2}'

const regexp = /\${([^{]+)}/g;
let result = msg2.replace(regexp, function(ignore, key){
    return eval(key);
});
console.log(result); // 'Hello Geoffrey'

It will replace ${name2} with his value.

I think what you are asking is the difference between RPC Literal, Document Literal and Document Wrapped SOAP web services.

Note that Document web services are delineated into literal and wrapped as well and they are different - one of the primary difference is that the latter is BP 1.1 compliant and the former is not.

Also, in Document Literal the operation to be invoked is not specified in terms of its name whereas in Wrapped, it is. This, I think, is a significant difference in terms of easily figuring out the operation name that the request is for.

In terms of RPC literal versus Document Wrapped, the Document Wrapped request can be easily vetted / validated against the schema in the WSDL - one big advantage.

I would suggest using Document Wrapped as the web service type of choice due to its advantages.

SOAP on HTTP is the SOAP protocol bound to HTTP as the carrier. SOAP could be over SMTP or XXX as well. SOAP provides a way of interaction between entities (client and servers, for example) and both entities can marshal operation arguments / return values as per the semantics of the protocol.

If you were using XML over HTTP (and you can), it is simply understood to be XML payload on HTTP request / response. You would need to provide the framework to marshal / unmarshal, error handling and so on.

You just need to override onCreateDialog in an Activity.

                return filename.contains(FTYPE) || sel.isDirectory();
            }

        };
        mFileList = mPath.list(filter);
    }

And if you don't want R to add decimals or zeros, you can stop it from drawing the x axis or the y axis or both using ...axt. Then, you can add your own ticks and labels:

plot(x, y, xaxt="n")
plot(x, y, yaxt="n")
axis(1 or 2, at=c(1, 5, 10), labels=c("First", "Second", "Third"))

Use an onsubmit attribute on the form tag rather than onclick on the submit.

Your code is correct, except you are adding (concatenating) strings, not adding integers. Just change your code into:

function compute() {
    if ( $('input[name=type]:checked').val() != undefined ) {
        var a = parseInt($('input[name=service_price]').val());
        var b = parseInt($('input[name=modem_price]').val());
        var total = a+b;
        $('#total_price').val(a+b);
    }
}

and this should work.

Here is some working example that updates the sum when the value when checkbox is checked (and if this is checked, the value is also updated when one of the fields is changed): jsfiddle.

Override the onsubmit action of the form to be a call to your function and add return false after it, ie:

<form onsubmit="javascript:myfunc();return false;" >

While Large Text File Viewer works great for just looking at a large file (and is free!), if the file is either a delimited or fixed-width file, then you should check out File Query. Not only can it open a file of any size (I have personally opened a 280GB file, but it can go larger), but it lets you query the file as though it was in a database as well, finding out any sort of information you could want from it.

It is not free though, so it is more for people that work with large files a lot, but if you have a one-off problem, you can just use the 30-day trial for free.

About efficient method. You can use CursorLoader. For example I included my action. And you must implement ContentProvider for your data base. https://developer.android.com/reference/android/content/ContentProvider.html

If you implement this, you will call you data base very efficient.

public class LoadEntitiesActionImp implements LoaderManager.LoaderCallbacks<Cursor> {

   public interface OnLoadEntities {
       void onSuccessLoadEntities(List<Entities> entitiesList);
   }

    private OnLoadEntities onLoadEntities;

    private final Context context;

    private final LoaderManager loaderManager;

    public LoadEntitiesActionImp(Context context, LoaderManager loaderManager) {
        this.context = context;
        this.loaderManager = loaderManager;
    }

    public void setCallback(OnLoadEntities onLoadEntities) {
        this.onLoadEntities = onLoadEntities;
    }

    public void loadEntities() {
        loaderManager.initLoader(LOADER_ID, null, this);
    }

    @Override
    public Loader<Cursor> onCreateLoader(int id, Bundle args) {
        return new CursorLoader(context, YOUR_URI, null, YOUR_SELECTION, YOUR_ARGUMENTS_FOR_SELECTION, YOUR_SORT_ORDER);
    }

    @Override
    public void onLoadFinished(Loader<Cursor> loader, Cursor cursor) {
    }

    @Override
    public void onLoaderReset(Loader<Cursor> loader) {
    }

I ran into this exact same error message. I tried Aditi's example, and then I realized what the real issue was. (Because I had another apiEndpoint making a similar call that worked fine.) In this case The object in my list had not had an interface extracted from it yet. So because I apparently missed a step, when it went to do the bind to the

List<OfthisModelType>

It failed to deserialize.

If you see this issue, check to see if that could be the issue.

If you need quick way to convert strings into bools (that functions with most strings) try.

def conv2bool(arg):
   try:
     res= (arg[0].upper()) == "T"
   except Exception,e:
     res= False
   return res # or do some more processing with arg if res is false

Not all programs do the same thing or run on the same hardware.

This is usually the answer why various language features exist. Arrays are a core computer science concept. Replacing arrays with lists/matrices/vectors/whatever advanced data structure would severely impact performance, and be downright impracticable in a number of systems. There are any number of cases where using one of these "advanced" data collection objects should be used because of the program in question.

In business programming (which most of us do), we can target hardware that is relatively powerful. Using a List in C# or Vector in Java is the right choice to make in these situations because these structures allow the developer to accomplish the goals faster, which in turn allows this type of software to be more featured.

When writing embedded software or an operating system an array may often be the better choice. While an array offers less functionality, it takes up less RAM, and the compiler can optimize code more efficiently for look-ups into arrays.

I am sure I am leaving out a number of the benefits for these cases, but I hope you get the point.

In my case it was getting install at a different python dist_package (python 3.5) whereas I was using python 3.6, so the below helped:

From Wikipedia http://en.wikipedia.org/wiki/Berkeley_sockets#bind.28.29

connect():

The connect() system call connects a socket, identified by its file descriptor, to a remote host specified by that host's address in the argument list.

Certain types of sockets are connectionless, most commonly user datagram protocol sockets. For these sockets, connect takes on a special meaning: the default target for sending and receiving data gets set to the given address, allowing the use of functions such as send() and recv() on connectionless sockets.

connect() returns an integer representing the error code: 0 represents success, while -1 represents an error.

bind():

bind() assigns a socket to an address. When a socket is created using socket(), it is only given a protocol family, but not assigned an address. This association with an address must be performed with the bind() system call before the socket can accept connections to other hosts. bind() takes three arguments:

sockfd, a descriptor representing the socket to perform the bind on. my_addr, a pointer to a sockaddr structure representing the address to bind to. addrlen, a socklen_t field specifying the size of the sockaddr structure. Bind() returns 0 on success and -1 if an error occurs.

Examples: 1.)Using Connect

#include <stdio.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <string.h>

int main(){
  int clientSocket;
  char buffer[1024];
  struct sockaddr_in serverAddr;
  socklen_t addr_size;

  /*---- Create the socket. The three arguments are: ----*/
  /* 1) Internet domain 2) Stream socket 3) Default protocol (TCP in this case) */
  clientSocket = socket(PF_INET, SOCK_STREAM, 0);

  /*---- Configure settings of the server address struct ----*/
  /* Address family = Internet */
  serverAddr.sin_family = AF_INET;
  /* Set port number, using htons function to use proper byte order */
  serverAddr.sin_port = htons(7891);
  /* Set the IP address to desired host to connect to */
  serverAddr.sin_addr.s_addr = inet_addr("192.168.1.17");
  /* Set all bits of the padding field to 0 */
  memset(serverAddr.sin_zero, '\0', sizeof serverAddr.sin_zero);  

  /*---- Connect the socket to the server using the address struct ----*/
  addr_size = sizeof serverAddr;
  connect(clientSocket, (struct sockaddr *) &serverAddr, addr_size);

  /*---- Read the message from the server into the buffer ----*/
  recv(clientSocket, buffer, 1024, 0);

  /*---- Print the received message ----*/
  printf("Data received: %s",buffer);   

  return 0;
}

2.)Bind Example:

int main()
{
    struct sockaddr_in source, destination = {};  //two sockets declared as previously
    int sock = 0;
    int datalen = 0;
    int pkt = 0;

    uint8_t *send_buffer, *recv_buffer;

    struct sockaddr_storage fromAddr;   // same as the previous entity struct sockaddr_storage serverStorage;
    unsigned int addrlen;  //in the previous example socklen_t addr_size;
    struct timeval tv;
    tv.tv_sec = 3;  /* 3 Seconds Time-out */
    tv.tv_usec = 0;

    /* creating the socket */         
    if ((sock = socket(AF_INET, SOCK_DGRAM, IPPROTO_UDP)) < 0) 
        printf("Failed to create socket\n");

    /*set the socket options*/
    setsockopt(sock, SOL_SOCKET, SO_RCVTIMEO, (char *)&tv, sizeof(struct timeval));

    /*Inititalize source to zero*/
    memset(&source, 0, sizeof(source));       //source is an instance of sockaddr_in. Initialization to zero
    /*Inititalize destinaton to zero*/
    memset(&destination, 0, sizeof(destination));


    /*---- Configure settings of the source address struct, WHERE THE PACKET IS COMING FROM ----*/
    /* Address family = Internet */
    source.sin_family = AF_INET;    
    /* Set IP address to localhost */   
    source.sin_addr.s_addr = INADDR_ANY;  //INADDR_ANY = 0.0.0.0
    /* Set port number, using htons function to use proper byte order */
    source.sin_port = htons(7005); 
    /* Set all bits of the padding field to 0 */
    memset(source.sin_zero, '\0', sizeof source.sin_zero); //optional


    /*bind socket to the source WHERE THE PACKET IS COMING FROM*/
    if (bind(sock, (struct sockaddr *) &source, sizeof(source)) < 0) 
        printf("Failed to bind socket");

    /* setting the destination, i.e our OWN IP ADDRESS AND PORT */
    destination.sin_family = AF_INET;                 
    destination.sin_addr.s_addr = inet_addr("127.0.0.1");  
    destination.sin_port = htons(7005); 

    //Creating a Buffer;
    send_buffer=(uint8_t *) malloc(350);
    recv_buffer=(uint8_t *) malloc(250);

    addrlen=sizeof(fromAddr);

    memset((void *) recv_buffer, 0, 250);
    memset((void *) send_buffer, 0, 350);

    sendto(sock, send_buffer, 20, 0,(struct sockaddr *) &destination, sizeof(destination));

    pkt=recvfrom(sock, recv_buffer, 98,0,(struct sockaddr *)&destination, &addrlen);
    if(pkt > 0)
        printf("%u bytes received\n", pkt);
    }

I hope that clarifies the difference

Please note that the socket type that you declare will depend on what you require, this is extremely important

If you are not limiting yourself to the standard library, I like psutil for this.

For instance to find all "python" processes:

>>> import psutil
>>> [p.info for p in psutil.process_iter(attrs=['pid', 'name']) if 'python' in p.info['name']]
[{'name': 'python3', 'pid': 21947},
 {'name': 'python', 'pid': 23835}]

An additional clarification is that factories can create functions/primitives, while services cannot. Check out this jsFiddle based on Epokk's: http://jsfiddle.net/skeller88/PxdSP/1351/.

The factory returns a function that can be invoked:

myApp.factory('helloWorldFromFactory', function() {
  return function() {
    return "Hello, World!";
  };
});

The factory can also return an object with a method that can be invoked:

myApp.factory('helloWorldFromFactory', function() {
  return {
    sayHello: function() {
      return "Hello, World!";
    }
  };
});

The service returns an object with a method that can be invoked:

myApp.service('helloWorldFromService', function() {
  this.sayHello = function() {
     return "Hello, World!";
  };
});

For more details, see a post I wrote on the difference: http://www.shanemkeller.com/tldr-services-vs-factories-in-angular/

PrimeNG has a native AutoComplete component with advanced features like templating and multiple selection.

Words in a text are always a source of randomness. Given a certain word, nothing can be inferred about the next word. For each word, we can take the ASCII codes of its letters, add those codes to form a number. The parity of this number is a good candidate for a random boolean.

Possible drawbacks:

1. this strategy is based upon using a text file as a source for the words. At some point, the end of the file will be reached. However, you can estimate how many times you are expected to call the randomBoolean() function from your app. If you will need to call it about 1 million times, then a text file with 1 million words will be enough. As a correction, you can use a stream of data from a live source like an online newspaper.

2. using some statistical analysis of the common phrases and idioms in a language, one can estimate the next word in a phrase, given the first words of the phrase, with some degree of accuracy. But statistically, these cases are rare, when we can accuratelly predict the next word. So, in most cases, the next word is independent on the previous words.

In Eclipse, in the root of my project, there is a file called 'the_comedy_of_errors' (no extension) - created with File> New > File , where I pasted some content from here: http://shakespeare.mit.edu/comedy_errors/comedy_errors.1.1.html

I think this should help:

Also documentations also prove that you can use require() for json files: https://www.bennadel.com/blog/2908-you-can-use-require-to-load-json-javascript-object-notation-files-in-node-js.htm

var jsonfile = require("./path/to/jsonfile.json");
node = jsonfile.adjacencies.nodeTo;
node2 = jsonfile.adjacencies.nodeFrom;
node3 = jsonfile.adjacencies.data.$color;
//other things.

Code like this

 <html>
    <head>
          <script type="text/javascript" src="path/to/script.js"></script>
          <!--other script and also external css included over here-->
    </head>
    <body>
        <form>
            <select name="users" onChange="showUser(this.value)">
               <option value="1">Tom</option>
               <option value="2">Bob</option>
               <option value="3">Joe</option>
            </select>
        </form>
    </body>
    </html>

I hope it will help you.... thanks

The answers mentioning canvas.width return the internal dimensions of the canvas, i.e. those specified when creating the element:

<canvas width="500" height="200">

If you size the canvas with CSS, its DOM dimensions are accessible via .scrollWidth and .scrollHeight:

var canvasElem = document.querySelector('canvas');_x000D_
document.querySelector('#dom-dims').innerHTML = 'Canvas DOM element width x height: ' +_x000D_
      canvasElem.scrollWidth +_x000D_
      ' x ' +_x000D_
      canvasElem.scrollHeight_x000D_
_x000D_
var canvasContext = canvasElem.getContext('2d');_x000D_
document.querySelector('#internal-dims').innerHTML = 'Canvas internal width x height: ' +_x000D_
      canvasContext.canvas.width +_x000D_
      ' x ' +_x000D_
      canvasContext.canvas.height;_x000D_
_x000D_
canvasContext.fillStyle = "#00A";_x000D_
canvasContext.fillText("Distorted", 0, 10);

<p id="dom-dims"></p>_x000D_
<p id="internal-dims"></p>_x000D_
<canvas style="width: 100%; height: 123px; border: 1px dashed black">

In general one could,

merge_list <- function(...) by(v<-unlist(c(...)),names(v),base::c)

Note that the by() solution returns an attributed list, so it will print differently, but will still be a list. But you can get rid of the attributes with attr(x,"_attribute.name_")<-NULL. You can probably also use aggregate().

You can construct it:

#modal-select-your-position li {
/* handle multiline */
    overflow: visible;
    padding-left: 17px;
    position: relative;
}

#modal-select-your-position li:before {
/* your own marker in content */
   content: "—";
   left: 0;
   position: absolute;
}

If you put something like this in your .ssh/config:

Host githost
HostName git.host.de
Port 4019
User root

then you should be able to use the basic syntax:

git push githost:/var/cache/git/project.git master

Using Javascript's es6 or node, you can do the following:

var [a,b,c,d] = [0,1,2,3]

And if you want to easily print multiple variables in a single line, just do this:

console.log(a, b, c, d)

0 1 2 3

This is similar to @alex gray 's answer here, but this example is in Javascript instead of CoffeeScript.

Note that this uses Javascript's array destructuring assignment

Apache shows php code instead of executing Issue fixed

1. Opened php5.6 conf or php7.x conf

# following command:

$ sudo vi /etc/apache2/mods-enabled/php5.6.conf

2. Commented following lines

3. Restarted the server

$ sudo service apache2 restart

4 Enjoy :)

I ran into the same problem every time it finds a special character marks it as ??. to solve this, I tried using the encoding: ISO-8859-1

BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream("txtPath"),"ISO-8859-1"));

while ((line = br.readLine()) != null) {

}

I hope this can help anyone who sees this post.

One of the benefits is you can use it in multiple views and have a consistent label text. It is also used by asp.net MVC scaffolding to generate the labels text and makes it easier to generate meaningful text

[Display(Name = "Wild and Crazy")]
public string WildAndCrazyProperty { get; set; }

"Wild and Crazy" shows up consistently wherever you use the property in your application.

Sometimes this is not flexible as you might want to change the text in some view. In that case, you will have to use custom markup like in your second example

One issue that may cause an ImagePullBackOff especially if you are pulling from a private registry is if the pod is not configured with the imagePullSecret of the private registry.

An authentication error may cause an imagePullBackOff.

I had a function defined in the wrong schema and without a public synonym. I.e. my proc was in schema "Dogs" and the function was in schema "Cats". The function didn't have a public synonym on it to allow Dogs to access the cats' function.

I saw a question the other day where someone inadvertently used an incomplete type by specifying something like

struct a {
    int q; 
}; 
struct A *x; 
x->q = 3;

The compiler knew that struct A was a struct, despite A being totally undefined, by virtue of the struct keyword.

That was in C++, where such usage of struct is atypical (and, it turns out, can lead to foot-shooting). In C if you do

typedef struct a {
    ...
} a;

then you can use a as the typename and omit the struct later. This will lead the compiler to give you an undefined identifier error later, rather than incomplete type, if you mistype the name or forget a header.

Once again the problem with unit-testing comes from manually creating objects using new operator. Consider passing already created Second instead:

class First {

  private Second second;

  public First(int num, Second second) {
    this.second = second;
    this.num = num;
  }

  // some other methods...

I know this might mean major rewrite of your API, but there is no other way. Also this class doesn't have any sense:

Mockito.when(new Second(any(String.class).thenReturn(null)));

First of all Mockito can only mock methods, not constructors. Secondly, even if you could mock constructor, you are mocking constructor of just created object and never really doing anything with that object.

Selecting the text to fix, and CtrlK, CtrlF shortcut certainly works. However, I generally find that if a particular method (for instance) has it's indentation messed up, simply removing the closing brace of the method, and re-adding, in fact fixes the indentation anyway, thereby doing without the need to select the code before hand, ergo is quicker. ymmv.

You can also try this, after injecting $window service.

$window.location.reload();

Two ways:

1. Implement ActionListener in your class, then use jBtnSelection.addActionListener(this); Later, you'll have to define a menthod, public void actionPerformed(ActionEvent e). However, doing this for multiple buttons can be confusing, because the actionPerformed method will have to check the source of each event (e.getSource()) to see which button it came from.

2. Use anonymous inner classes:

jBtnSelection.addActionListener(new ActionListener() { 
  public void actionPerformed(ActionEvent e) { 
    selectionButtonPressed();
  } 
} );

Later, you'll have to define selectionButtonPressed(). This works better when you have multiple buttons, because your calls to individual methods for handling the actions are right next to the definition of the button.

The second method also allows you to call the selection method directly. In this case, you could call selectionButtonPressed() if some other action happens, too - like, when a timer goes off or something (but in this case, your method would be named something different, maybe selectionChanged()).

I solved the problem by configuring the build path. Right click on the project(or any of the subfolders)-> Build path -> Configure build path. Once the property window opens up, click on the 'Source' tab and add your src and tst folders. But this alone did not work for me. Strangely, I had to retype the annotations.(Project->clean or restart might also have worked though).

you can check length of items

ng-show="items.length"

If you don't want to use $(this).val(), you can try:

var file_onchange = function () {
  var input = this; // avoid using 'this' directly

  if (input.files && input.files[0]) {
    var type = input.files[0].type; // image/jpg, image/png, image/jpeg...

    // allow jpg, png, jpeg, bmp, gif, ico
    var type_reg = /^image\/(jpg|png|jpeg|bmp|gif|ico)$/;

    if (type_reg.test(type)) {
      // file is ready to upload
    } else {
      alert('This file type is unsupported.');
    }
  }
};

$('#file').on('change', file_onchange);

Hope this helps!

It is a Generic Type Parameter.

A generic type parameter allows you to specify an arbitrary type T to a method at compile-time, without specifying a concrete type in the method or class declaration.

For example:

public T[] Reverse<T>(T[] array)
{
    var result = new T[array.Length];
    int j=0;
    for(int i=array.Length - 1; i>= 0; i--)
    {
        result[j] = array[i];
        j++;
    }
    return result;
}

reverses the elements in an array. The key point here is that the array elements can be of any type, and the function will still work. You specify the type in the method call; type safety is still guaranteed.

So, to reverse an array of strings:

string[] array = new string[] { "1", "2", "3", "4", "5" };
var result = reverse(array);

Will produce a string array in result of { "5", "4", "3", "2", "1" }

This has the same effect as if you had called an ordinary (non-generic) method that looks like this:

public string[] Reverse(string[] array)
{
    var result = new string[array.Length];
    int j=0;
    for(int i=array.Length - 1; i >= 0; i--)
    {
        result[j] = array[i];
        j++;
    }
    return result;
}

The compiler sees that array contains strings, so it returns an array of strings. Type string is substituted for the T type parameter.

Generic type parameters can also be used to create generic classes. In the example you gave of a SampleCollection<T>, the T is a placeholder for an arbitrary type; it means that SampleCollection can represent a collection of objects, the type of which you specify when you create the collection.

So:

var collection = new SampleCollection<string>();

creates a collection that can hold strings. The Reverse method illustrated above, in a somewhat different form, can be used to reverse the collection's members.

So far I have found two quick ways in cmd linux

1. Use old school mail

mail -s "$(echo -e "This is Subject\nContent-Type: text/html")" [email protected] < mytest.html

1. Use mutt

mutt -e "my_hdr Content-Type: text/html" [email protected] -s "subject" < mytest.html

I had the same problem with Visual Studio 2015 and Resharper 9.2

"Resharper 9 keyboard shortcuts not working in Visual Studio 2015"

I had tried all possible resetting and applying keyboard schemes and found the answer from Yuri Fedoseev.

My Windows 10 language configuration only had Swedish in the language preferences "Control Panel\Clock, Language, and Region\Language"

The solution was to add English(I chose the US version) in the language list. And then go to Resharper > Options > Keyboard & Menus > Apply Scheme. (perhaps you do not even need to apply the scheme)

Here is a pure-java implementation of background image repeating:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Bitmap bmp = BitmapFactory.decodeResource(getResources(), R.drawable.bg_image);
    BitmapDrawable bitmapDrawable = new BitmapDrawable(bmp);
    bitmapDrawable.setTileModeXY(Shader.TileMode.REPEAT, Shader.TileMode.REPEAT);
    LinearLayout layout = new LinearLayout(this);
    layout.setBackgroundDrawable(bitmapDrawable);
}

In this case, our background image would have to be stored in res/drawable/bg_image.png.

You could use DataGrid in WPF

SqlDataAdapter da = new SqlDataAdapter("Select * from Table",con);
DataTable dt = new DataTable("Call Reciept");
da.Fill(dt);
DataGrid dg = new DataGrid();
dg.ItemsSource = dt.DefaultView;

It looks that 3.15 offers no satisfying solution: either one uses the old style with Cell.CELL_TYPE_*, or we use the method getCellTypeEnum() which is marked as deprecated. A lot of disturbances for little add value...

When working with flags I often declare additional None and All items. These are helpful to check whether all flags are set or no flag is set.

[Flags] 
enum SuitsFlags { 

    None =     0,

    Spades =   1 << 0, 
    Clubs =    1 << 1, 
    Diamonds = 1 << 2, 
    Hearts =   1 << 3,

    All =      ~(~0 << 4)

}

Usage:

Spades | Clubs | Diamonds | Hearts == All  // true
Spades & Clubs == None  // true

 
Update 2019-10:

Since C# 7.0 you can use binary literals, which are probably more intuitive to read:

[Flags] 
enum SuitsFlags { 

    None =     0b0000,

    Spades =   0b0001, 
    Clubs =    0b0010, 
    Diamonds = 0b0100, 
    Hearts =   0b1000,

    All =      0b1111

}

[EDIT 2020]-> Now I totally recommend the answer here, way easier using android studio, faster and no need to wright any code - the one below was back in the eclipse days :) -.

You can use this code in any activity. It will log the hashkey in the logcat, which is the debug key. This is easy, and it's a relief than using SSL.

PackageInfo info;
try {
    info = getPackageManager().getPackageInfo("com.you.name", PackageManager.GET_SIGNATURES);
    for (Signature signature : info.signatures) {
        MessageDigest md;
        md = MessageDigest.getInstance("SHA");
        md.update(signature.toByteArray());
        String something = new String(Base64.encode(md.digest(), 0));
        //String something = new String(Base64.encodeBytes(md.digest()));
        Log.e("hash key", something);
    }
} catch (NameNotFoundException e1) {
    Log.e("name not found", e1.toString());
} catch (NoSuchAlgorithmException e) {
    Log.e("no such an algorithm", e.toString());
} catch (Exception e) {
    Log.e("exception", e.toString());
}

You can delete the code after knowing the key ;)

MySQLi stands for MySQL improved. It's an object-oriented interface to the MySQL bindings which makes things easier to use. It also offers support for prepared statements (which are very useful). If you're on PHP 5 use MySQLi.

      }

      int i = 5;

      while (i * i <= n)
      {
        if (n % i == 0 || n % (i + 2) == 0)
        {
          retVal = false;

Using BufferedReader:

import java.io.BufferedReader;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;

BufferedReader br;
try {
    br = new BufferedReader(new FileReader("/fileToRead.txt"));
    try {
        String x;
        while ( (x = br.readLine()) != null ) {
            // Printing out each line in the file
            System.out.println(x);
        }
    }
    catch (IOException e) {
        e.printStackTrace();
    }
}
catch (FileNotFoundException e) {
    System.out.println(e);
    e.printStackTrace();
}

In my case i have multiple sections and both the section and row index is vital, so in such a case i just created a property on UIButton which i set the cell indexPath like so:

fileprivate struct AssociatedKeys {
    static var index = 0
}

extension UIButton {

    var indexPath: IndexPath? {
        get {
            return objc_getAssociatedObject(self, &AssociatedKeys.index) as? IndexPath
        }
        set {
            objc_setAssociatedObject(self, &AssociatedKeys.index, newValue, .OBJC_ASSOCIATION_RETAIN_NONATOMIC)
        }
    }
}

Then set the property in cellForRowAt like this :

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCellWithIdentifier("Cell") as! Cell
    cell.button.indexPath = indexPath
}

Then in the handleTapAction you can get the indexPath like this :

@objc func handleTapAction(_ sender: UIButton) {
    self.selectedIndex = sender.indexPath

}

(SELECT ename FROM EMP WHERE empno = mgr)

There are no records in EMP that meet this criteria.

You need to self-join to get this relation.

SELECT e.ename AS Employee, e.empno, m.ename AS Manager, m.empno
FROM EMP AS e LEFT OUTER JOIN EMP AS m
ON e.mgr =m.empno;

EDIT:

The answer you selected will not list your president because it's an inner join. I'm thinking you'll be back when you discover your output isn't what your (I suspect) homework assignment required. Here's the actual test case:

> select * from emp;

 empno | ename |    job    | deptno | mgr  
-------+-------+-----------+--------+------
  7839 | king  | president |     10 |     
  7698 | blake | manager   |     30 | 7839
(2 rows)

> SELECT e.ename employee, e.empno, m.ename manager, m.empno
FROM emp AS e LEFT OUTER JOIN emp AS m
ON e.mgr =m.empno;

 employee | empno | manager | empno 
----------+-------+---------+-------
 king     |  7839 |         |      
 blake    |  7698 | king    |  7839
(2 rows)

The difference is that an outer join returns all the rows. An inner join will produce the following:

> SELECT e.ename, e.empno, m.ename as manager, e.mgr
FROM emp e, emp m
WHERE e.mgr = m.empno;

 ename | empno | manager | mgr  
-------+-------+---------+------
 blake |  7698 | king    | 7839
(1 row)

Here's some possible solutions: JQuery History Salajax A Better Ajax Back Button

Necromancing:

It's relativiely simple to emulate a COUNT DISTINCT over PARTITION BY with MAX via DENSE_RANK:

;WITH baseTable AS
(
    SELECT 'RM1' AS RM, 'ADR1' AS ADR
    UNION ALL SELECT 'RM1' AS RM, 'ADR1' AS ADR
    UNION ALL SELECT 'RM2' AS RM, 'ADR1' AS ADR
    UNION ALL SELECT 'RM2' AS RM, 'ADR2' AS ADR
    UNION ALL SELECT 'RM2' AS RM, 'ADR2' AS ADR
    UNION ALL SELECT 'RM2' AS RM, 'ADR3' AS ADR
    UNION ALL SELECT 'RM3' AS RM, 'ADR1' AS ADR
    UNION ALL SELECT 'RM2' AS RM, 'ADR1' AS ADR
    UNION ALL SELECT 'RM3' AS RM, 'ADR1' AS ADR
    UNION ALL SELECT 'RM3' AS RM, 'ADR2' AS ADR
)
,CTE AS
(
    SELECT RM, ADR, DENSE_RANK() OVER(PARTITION BY RM ORDER BY ADR) AS dr 
    FROM baseTable
)
SELECT
     RM
    ,ADR

    ,COUNT(CTE.ADR) OVER (PARTITION BY CTE.RM ORDER BY ADR) AS cnt1 
    ,COUNT(CTE.ADR) OVER (PARTITION BY CTE.RM) AS cnt2 
    -- Not supported
    --,COUNT(DISTINCT CTE.ADR) OVER (PARTITION BY CTE.RM ORDER BY CTE.ADR) AS cntDist
    ,MAX(CTE.dr) OVER (PARTITION BY CTE.RM ORDER BY CTE.RM) AS cntDistEmu 
FROM CTE

Note:
This assumes the fields in question are NON-nullable fields.
If there is one or more NULL-entries in the fields, you need to subtract 1.

Using ng-pattern on the text field:

<input type="text"  ng-model="myText" name="inputName" ng-pattern="onlyNumbers">

Then include this on your controller

$scope.onlyNumbers = /^\d+$/;

Below solution worked for me.

CONVERT( Table1.FromColumn USING utf8)    =  CONVERT(Table2.ToColumn USING utf8) 

It doesn't do anything -- the under/overflow just happens.

A "-1" that is the result of a computation that overflowed is no different from the "-1" that resulted from any other information. So you can't tell via some status or by inspecting just a value whether it's overflowed.

But you can be smart about your computations in order to avoid overflow, if it matters, or at least know when it will happen. What's your situation?
