Edit: This is out of date, see @Merlin's answer.

[False], being a nonempty list, is not the same as False. You should write:

test = df.sort('one', ascending=False)

Path.GetDirectoryName(System.Diagnostics.Process.GetCurrentProcess().MainModule.FileName) Is the only one that has worked for me in every case I have tried.

I used a method similar to user496892:

SPBoundField hiddenField = new SPBoundField();
hiddenField.HeaderText = "Header";
hiddenField.DataField = "DataFieldName";
grid.Columns.Add(hiddenField);

grid.DataSource = myDataSource;
grid.DataBind();

hiddenField.Visible = false;

To solve your question definitely need to use the Style and Template for the Button. But how exactly does he look like? Decisions may be several. For example, Button are two texts to better define the relevant TextBlocks? Can be directly in the template, but then use the buttons will be limited, because the template can be only one ContentPresenter. I decided to do things differently, to identify one ContentPresenter with an icon in the form of a Path, and the content is set using the buttons on the side.

The style:

<Style TargetType="{x:Type Button}">
    <Setter Property="Background" Value="#373737" />
    <Setter Property="Foreground" Value="White" />
    <Setter Property="FontSize" Value="15" />
    <Setter Property="SnapsToDevicePixels" Value="True" />

    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type Button}">
                <Border CornerRadius="4" Background="{TemplateBinding Background}">
                    <Grid>
                        <Path x:Name="PathIcon" Width="15" Height="25" Stretch="Fill" Fill="#4C87B3" HorizontalAlignment="Left" Margin="17,0,0,0" Data="F1 M 30.0833,22.1667L 50.6665,37.6043L 50.6665,38.7918L 30.0833,53.8333L 30.0833,22.1667 Z "/>
                        <ContentPresenter x:Name="MyContentPresenter" Content="{TemplateBinding Content}" HorizontalAlignment="Center" VerticalAlignment="Center" Margin="0,0,0,0" />                                
                    </Grid>
                </Border>

                <ControlTemplate.Triggers>
                    <Trigger Property="IsMouseOver" Value="True">
                        <Setter Property="Background" Value="#E59400" />
                        <Setter Property="Foreground" Value="White" />
                        <Setter TargetName="PathIcon" Property="Fill" Value="Black" />
                    </Trigger>

                    <Trigger Property="IsPressed" Value="True">
                        <Setter Property="Background" Value="OrangeRed" />
                        <Setter Property="Foreground" Value="White" />
                    </Trigger>
                </ControlTemplate.Triggers>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

Sample of using:

<Button Width="200" Height="50" VerticalAlignment="Top" Margin="0,20,0,0" />
    <Button.Content>
        <StackPanel>
            <TextBlock Text="Watch Now" FontSize="20" />
            <TextBlock Text="Duration: 50m" FontSize="12" Foreground="Gainsboro" />
        </StackPanel>
    </Button.Content>
</Button>

Output

It is best to StackPanel determine the Resources and set the Button so:

<Window.Resources>
    <StackPanel x:Key="MyStackPanel">
        <TextBlock Name="MainContent" Text="Watch Now" FontSize="20" />
        <TextBlock Name="DurationValue" Text="Duration: 50m" FontSize="12" Foreground="Gainsboro" />
    </StackPanel>
</Window.Resources>

<Button Width="200" Height="50" Content="{StaticResource MyStackPanel}" VerticalAlignment="Top" Margin="0,20,0,0" />

The question remains with setting the value for TextBlock Duration, because this value must be dynamic. I implemented it using attached DependencyProperty. Set it to the window, like that:

<Window Name="MyWindow" local:MyDependencyClass.CurrentDuration="Duration: 50m" ... />

Using in TextBlock:

<TextBlock Name="DurationValue" Text="{Binding ElementName=MyWindow, Path=(local:MyDependencyClass.CurrentDuration)}" FontSize="12" Foreground="Gainsboro" />

In fact, there is no difference for anyone to determine the attached DependencyProperty, because it is the predominant feature.

Example of set value:

private void Button_Click(object sender, RoutedEventArgs e)
{
    MyDependencyClass.SetCurrentDuration(MyWindow, "Duration: 101m");
}

Code behind

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
    }

    private void Button_Click(object sender, RoutedEventArgs e)
    {
        MyDependencyClass.SetCurrentDuration(MyWindow, "Duration: 101m");
    }
}

public class MyDependencyClass : DependencyObject
{
    public static readonly DependencyProperty CurrentDurationProperty;        

    public static void SetCurrentDuration(DependencyObject DepObject, string value)
    {
        DepObject.SetValue(CurrentDurationProperty, value);
    }

    public static string GetCurrentDuration(DependencyObject DepObject)
    {
        return (string)DepObject.GetValue(CurrentDurationProperty);
    }

    static MyDependencyClass()
    {
        PropertyMetadata MyPropertyMetadata = new PropertyMetadata("Duration: 0m");

        CurrentDurationProperty = DependencyProperty.RegisterAttached("CurrentDuration",
                                                            typeof(string),
                                                            typeof(MyDependencyClass),
                                                            MyPropertyMetadata);
    }
}

Along with Bootstrap 3 I used this code. The second set of rules just undo what bootstrap does for focus/active buttons:

button::-moz-focus-inner {
  border: 0;    /*removes dotted lines around buttons*/
}

.btn.active.focus, .btn.active:focus, .btn.focus, .btn.focus:active, .btn:active:focus, .btn:focus{
  outline:0;
}

NOTE that your custom css file should come after Bootstrap css file in your html code to override it.

For swift 2.0 and above do this

@IBOutlet weak var imageView: UIImageView!
    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        let tap = UITapGestureRecognizer(target: self, action: #selector(ViewController.tappedMe))
        imageView.addGestureRecognizer(tap)
        imageView.userInteractionEnabled = true
    }
    func tappedMe()
    {
        print("Tapped on Image")
    }

You can start reading from here jQuery.ajax()

Actually Controller Action is a public method which can be accessed through Url. So any call of an Action from an Ajax call, either MicrosoftMvcAjax or jQuery can be made. For me, jQuery is the simplest one. It got a lots of examples in the link I gave above. The typical example for an ajax call is like this.

$.ajax({
    // edit to add steve's suggestion.
    //url: "/ControllerName/ActionName",
    url: '<%= Url.Action("ActionName", "ControllerName") %>',
    success: function(data) {
         // your data could be a View or Json or what ever you returned in your action method 
         // parse your data here
         alert(data);
    }
});

More examples can be found in here

For Windows:

pip install --upgrade pip wheel
pip install bzt
pip install lxml

You CAN use UTF-8 in the POST request, all you need is to specify the charset in your request.

You should use this request:

curl -X POST -H "Content-Type: application/x-www-form-urlencoded; charset=utf-8" --data-ascii "content=derinhält&date=asdf" http://myserverurl.com/api/v1/somemethod

This is an oldie, and there are a few solutions out there, but I came up with a shorter and simpler formula than any other I encountered, and it might be useful to anyone passing by.

I have named the colors list Colors (A2:A7), and the array formula put in cell C2 is this (fixed):

=IFERROR(INDEX(Colors,MATCH(SUM(COUNTIF(C$1:C1,Colors)),COUNTIF(Colors,"<"&Colors),0)),"")

Use Ctrl+Shift+Enter to enter the formula in C2, and copy C2 down to C3:C7.

Explanation with sample data {"red"; "blue"; "red"; "green"; "blue"; "black"}:

1. COUNTIF(Colors,"<"&Colors) returns an array (#1) with the count of values that are smaller then each item in the data {4;1;4;3;1;0} (black=0 items smaller, blue=1 item, red=4 items). This can be translated to a sort value for each item.
2. COUNTIF(C$1:C...,Colors) returns an array (#2) with 1 for each data item that is already in the sorted result. In C2 it returns {0;0;0;0;0;0} and in C3 {0;0;0;0;0;1} because "black" is first in the sort and last in the data. In C4 {0;1;0;0;1;1} it indicates "black" and all the occurrences of "blue" are already present.
3. The SUM returns the k-th sort value, by counting all the smaller values occurrences that are already present (sum of array #2).
4. MATCH finds the first index of the k-th sort value (index in array #1).
5. The IFERROR is only to hide the #N/A error in the bottom cells, when the sorted unique list is complete.

To know how many unique items you have you can use this regular formula:

=SUM(IF(FREQUENCY(COUNTIF(Colors,"<"&Colors),COUNTIF(Colors,"<"&Colors)),1))

Both store memory addresses to the first elements of two different arrays. These addresses can't be equal hence the output.

Try this

$('#D25,#E37,#E31,#F37,#E16,#E40,#F16,#F40,#E41,#F41').bind('DOMNodeInserted DOMNodeRemoved',function(){
          // your code;
       });

Do not use this. This may crash the page.

$('mydiv').bind("DOMSubtreeModified",function(){
  alert('changed');
});

1. Start -> Run -> perfmon
2. Look at the zillions of counters that SQL Server installs

This is what I do on mine

$(document).ready(function() {
  if ($('#userForm').valid()) {
    var formData = $("#userForm").serializeArray();
    $.ajax({
      url: 'http://www.example.com/user/' + $('#Id').val() + '?callback=?',
      type: "GET",
      data: formData,
      dataType: "jsonp",
      jsonpCallback: "localJsonpCallback"
    });
  });

function localJsonpCallback(json) {
  if (!json.Error) {
    $('#resultForm').submit();
  } else {
    $('#loading').hide();
    $('#userForm').show();
    alert(json.Message);
  }
}

You can have - characters in your images. Assume you have a local image (not a local registry) named centos-base-image with tag 7.3.1611.

In the example above FROM is fetching your local image, you can provide additional instructions to fetch an image from your custom registry (e.g. FROM localhost:5000/my-image:with.tag). See https://docs.docker.com/engine/reference/commandline/pull/#pull-from-a-different-registry and https://docs.docker.com/registry/#tldr

Finally, if your image is not being resolved when providing a name, try adding a tag to the image when you create it

This GitHub thread describes a similar issue of not finding local images by name.

By omitting a specific tag, docker will look for an image tagged "latest", so either create an image with the :latest tag, or change your FROM

Editor's note: disabling SSL verification has security implications. Without verification of the authenticity of SSL/HTTPS connections, a malicious attacker can impersonate a trusted endpoint such as Gmail, and you'll be vulnerable to a Man-in-the-Middle Attack.

Be sure you fully understand the security issues before using this as a solution.

I have also this error in laravel 4.2 I solved like this way. Find out StreamBuffer.php. For me I use xampp and my project name is itis_db for this my path is like this. So try to find according to your one

C:\xampp\htdocs\itis_db\vendor\swiftmailer\swiftmailer\lib\classes\Swift\Transport\StreamBuffer.php

and find out this function inside StreamBuffer.php

private function _establishSocketConnection()

and paste this two lines inside of this function

$options['ssl']['verify_peer'] = FALSE;
$options['ssl']['verify_peer_name'] = FALSE;

and reload your browser and try to run your project again. For me I put on like this:

private function _establishSocketConnection()
{
    $host = $this->_params['host'];
    if (!empty($this->_params['protocol'])) {
        $host = $this->_params['protocol'].'://'.$host;
    }
    $timeout = 15;
    if (!empty($this->_params['timeout'])) {
        $timeout = $this->_params['timeout'];
    }
    $options = array();
    if (!empty($this->_params['sourceIp'])) {
        $options['socket']['bindto'] = $this->_params['sourceIp'].':0';
    }
    
   $options['ssl']['verify_peer'] = FALSE;
    $options['ssl']['verify_peer_name'] = FALSE;

    $this->_stream = @stream_socket_client($host.':'.$this->_params['port'], $errno, $errstr, $timeout, STREAM_CLIENT_CONNECT, stream_context_create($options));
    if (false === $this->_stream) {
        throw new Swift_TransportException(
            'Connection could not be established with host '.$this->_params['host'].
            ' ['.$errstr.' #'.$errno.']'
            );
    }
    if (!empty($this->_params['blocking'])) {
        stream_set_blocking($this->_stream, 1);
    } else {
        stream_set_blocking($this->_stream, 0);
    }
    stream_set_timeout($this->_stream, $timeout);
    $this->_in = &$this->_stream;
    $this->_out = &$this->_stream;
}

Hope you will solve this problem.....

You don't need to use anything but plain React and ES6 to achieve what you want. As per Jim's answer, just define the constant in the right place. I like the idea of keeping the constant local to the component if not needed externally. The below is an example of possible usage.

import React from "react";

const sizeToLetterMap = {
  small_square: 's',
  large_square: 'q',
  thumbnail: 't',
  small_240: 'm',
  small_320: 'n',
  medium_640: 'z',
  medium_800: 'c',
  large_1024: 'b',
  large_1600: 'h',
  large_2048: 'k',
  original: 'o'
};

class PhotoComponent extends React.Component {
  constructor(args) {
    super(args);
  }

  photoUrl(image, size_text) {
    return (<span>
      Image: {image}, Size Letter: {sizeToLetterMap[size_text]}
    </span>);
  }

  render() {
    return (
      <div className="photo-wrapper">
        The url is: {this.photoUrl(this.props.image, this.props.size_text)}
      </div>
    )
  }
}

export default PhotoComponent;

// Call this with <PhotoComponent image="abc.png" size_text="thumbnail" />
// Of course the component must first be imported where used, example:
// import PhotoComponent from "./photo_component.jsx";

The ObjectiveC equivalent is:

    myView.translatesAutoresizingMaskIntoConstraints = NO;

    [[myView.centerXAnchor constraintEqualToAnchor:self.view.centerXAnchor] setActive:YES];

    [[myView.centerYAnchor constraintEqualToAnchor:self.view.centerYAnchor] setActive:YES];

The sys.path list contains the list of directories which will be searched for modules at runtime:

python -v
>>> import sys
>>> sys.path
['', '/usr/local/lib/python25.zip', '/usr/local/lib/python2.5', ... ]

Anonymous FTP usage is covered by RFC 1635: How to Use Anonymous FTP:

What is Anonymous FTP?

Anonymous FTP is a means by which archive sites allow general access to their archives of information. These sites create a special account called "anonymous".

…

Traditionally, this special anonymous user account accepts any string as a password, although it is common to use either the password "guest" or one's electronic mail (e-mail) address. Some archive sites now explicitly ask for the user's e-mail address and will not allow login with the "guest" password. Providing an e-mail address is a courtesy that allows archive site operators to get some idea of who is using their services.

These are general recommendations, though. Each FTP server may have its own guidelines.

For sample use of the ftp command on anonymous FTP access, see appendix A:

    Dim v: v = s  'Cast to variant for 64-bit VBA support
    With CreateObject("htmlfile")
    With .parentWindow.clipboardData
        Select Case True
            Case Len(s): .setData "text", v
            Case Else:   Clipboard = .getData("text")
        End Select
    End With
    End With
End Function

'Three examples of copying text to the clipboard:
Clipboard "Excel Hero was here."
Clipboard var1 & vbLF & var2
Clipboard 123

'To read text from the clipboard:
MsgBox Clipboard

This is a solution that does NOT use MS Forms nor the Win32 API. Instead it uses the Microsoft HTML Object Library which is fast and ubiquitous and NOT deprecated by Microsoft like MS Forms. And this solution respects line feeds. This solution also works from 64-bit Office. Finally, this solution allows both writing to and reading from the Windows clipboard. No other solution on this page has these benefits.

A char is an integral type. When you write

char ch = 'A';

you're setting the value of ch to whatever number your compiler uses to represent the character 'A'. That's usually the ASCII code for 'A' these days, but that's not required. You're almost certainly using a system that uses ASCII.

Like any numeric type, you can initialize it with an ordinary number:

char ch = 13;

If you want do do arithmetic on a char value, just do it: ch = ch + 1; etc.

However, in order to display the value you have to get around the assumption in the iostreams library that you want to display char values as characters rather than numbers. There are a couple of ways to do that.

std::cout << +ch << '\n';
std::cout << int(ch) << '\n'

You can simply use:

mvn --settings YourOwnSettings.xml clean install

or

mvn -s YourOwnSettings.xml clean install

You don't need to create an extension method for this

@Url.Action("Action", "Controller", values: null);

• Action - Name of the action
• Controller - Name of the controller
• values - Object containing route values: aka GET parameters

There are also lots of other overloads to Url.Action you can use to generate links.

If you are using chart.js in an Angular project with Typescript, the you can try the following;

Import the library:
    import { Chart } from 'chart.js';

In your Component Class declare the variable and define a method:

  chart: Chart;

  drawGraph(): void {
    if (this.chart) {
      this.chart.destroy();
    }

    this.chart = new Chart('myChart', {
       .........
    });
  }


In HTML Template:
<canvas id="myChart"></canvas>

The reason csv doesn't support that is because variable-length lines are not really supported on most filesystems. What you should do instead is collect all the data in lists, then call zip() on them to transpose them after.

>>> l = [('Result_1', 'Result_2', 'Result_3', 'Result_4'), (1, 2, 3, 4), (5, 6, 7, 8)]
>>> zip(*l)
[('Result_1', 1, 5), ('Result_2', 2, 6), ('Result_3', 3, 7), ('Result_4', 4, 8)]

Similar to another solution here, with minor modification:

<form method="METHOD" id="FORMID">
   <!-- ...your inputs -->
</form>
<button type="submit" form="FORMID" value="Submit">Submit</button>

I've gone through these posts and somehow ended up finding a simple answer, which I'm posting here for those how want short and sweet solutions:

1. Use console.log("Hello World") in your script.
2. Go to https://script.google.com/home/my and select your add-on.
3. Click on the ellipsis menu on Project Details, select Executions.

4. Click on the header of the latest execution and read the log.

It's possible in ggplot and you can use scale_date for this task

 library(ggplot2)  
 Lines <- "Date            Visits
    11/1/2010   696537
    11/2/2010   718748
    11/3/2010   799355
    11/4/2010   805800
    11/5/2010   701262
    11/6/2010   531579
    11/7/2010   690068
    11/8/2010   756947
    11/9/2010   718757
    11/10/2010  701768
    11/11/2010  820113
    11/12/2010  645259"
    dm <- read.table(textConnection(Lines), header = TRUE)
    dm <- mutate(dm, Date = as.Date(dm$Date, "%m/%d/%Y"))
    ggplot(data = dm, aes(Date, Visits)) + 
    geom_line() + 
    scale_x_date(format = "%b %d", major =  "1 day")

You can also do it like this

public Map<Boolean, List<Student>> getpartitionMap(List<Student> studentsList) {

    List<Predicate<Student>> allPredicates = getAllPredicates();
    Predicate<Student> compositePredicate =  allPredicates.stream()
                             .reduce(w -> true, Predicate::and)
     Map<Boolean, List<Student>> studentsMap= studentsList
                .stream()
                .collect(Collectors.partitioningBy(compositePredicate));
    return studentsMap;
}

public List<Student> getValidStudentsList(Map<Boolean, List<Student>> studentsMap) throws Exception {

    List<Student> validStudentsList =  studentsMap.entrySet()
             .stream()
             .filter(p -> p.getKey() == Boolean.TRUE)
             .flatMap(p -> p.getValue().stream())
             .collect(Collectors.toList());

    return validStudentsList;
}

public List<Student> getInValidStudentsList(Map<Boolean, List<Student>> studentsMap) throws Exception {

    List<Student> invalidStudentsList = 
             partionedByPredicate.entrySet()
             .stream()
             .filter(p -> p.getKey() == Boolean.FALSE)
             .flatMap(p -> p.getValue().stream())
             .collect(Collectors.toList());

    return invalidStudentsList;

}

With flatMap you will get just List<Student> instead of List<List<Student>>.

Thanks

Project -> Clean -> Clean all Projects and then Project -> Build Project worked for me (I did the un-checking generate make-file automatically and then rechecking it before doing this). This was for an AVR (micro-processor programming) project through the AVR CDT plugin in eclipse Juno though.

You need to make sure that all possible divisors don't evenly divide the number you're checking. In this case you'll print the number you're checking any time just one of the possible divisors doesn't evenly divide the number.

Also you don't want to use a continue statement because a continue will just cause it to check the next possible divisor when you've already found out that the number is not a prime.

var dateObj = new Date();
var month = dateObj.getUTCMonth() + 1; //months from 1-12
var day = dateObj.getUTCDate();
var year = dateObj.getUTCFullYear();

newdate = year + "/" + month + "/" + day;

or you can set new date and give the above values

In Angular earlier we had .angular-cli.json file which referred to favicon.ico. If you'll upgrade into one of the newer versions of Angular then you'll have angular.json instead. For these newer versions, you have to refer the favicon path in your index.html from now onwards.

If you are

• trying to communicate between two containers from different docker-compose projects and don't want to use the same network (because let's say they would have PostgreSQL or Redis container on the same port and you would prefer to not changing these ports and not use it at the same network)
• developing locally and want to imitate communication between two docker compose projects
• running two docker-compose projects on localhost
• developing especially Django apps or Django Rest Framework (drf) API and running app inside container on some exposed port
• getting Connection refused while trying to communicate between two containers

And you want to

• container api_a communicate to api_b (or vice versa) without the same "docker network"

(example below)

you can use "host" of the second container as IP of your computer and port that is mapped from inside Docker container. You can obtain IP of your computer with this script (from: Finding local IP addresses using Python's stdlib):

import socket
def get_ip():
    s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
    try:
        # doesn't even have to be reachable
        s.connect(('10.255.255.255', 1))
        IP = s.getsockname()[0]
    except:
        IP = '127.0.0.1'
    finally:
        s.close()
    return IP

Example:

project_api_a/docker-compose.yml:

networks:
  app-tier:
    driver: bridge

services:
  api:
    container_name: api_a
    image: api_a:latest
    depends_on:
      - postgresql
    networks:
      - app-tier

inside api_a container you are running Django app: manage.py runserver 0.0.0.0:8000

and second docker-compose.yml from other project:

project_api_b/docker-compose-yml :

networks:
  app-tier:
    driver: bridge

services:
  api:
    container_name: api_b
    image: api_b:latest
    depends_on:
      - postgresql
    networks:
      - app-tier

inside api_b container you are running Django app: manage.py runserver 0.0.0.0:8001

And trying to connect from container api_a to api_b then URL of api_b container will be: http://<get_ip_from_script_above>:8001/

It can be especially valuable if you are using even more than two(three or more) docker-compose projects and it's hard to provide common network for all of it - it's good workaround and solution

Java is a server side language, whereas javascript is a client side language. Both cannot communicate. If you have setup some server side script using Java you could use AJAX on the client in order to send an asynchronous request to it and thus invoke any possible Java functions. For example if you use jQuery as js framework you may take a look at the $.ajax() method. Or if you wanted to do it using plain javascript, here's a tutorial.

If you just want the bitmap, This too works

InputStream inputStream = mContext.getContentResolver().openInputStream(uri);
Bitmap bmp = BitmapFactory.decodeStream(inputStream);
if( inputStream != null ) inputStream.close();

sample uri : content://media/external/images/media/12345

You need to put the files into an array in order to sort and find the last modified file.

$files = array();
if ($handle = opendir('.')) {
    while (false !== ($file = readdir($handle))) {
        if ($file != "." && $file != "..") {
           $files[filemtime($file)] = $file;
        }
    }
    closedir($handle);

    // sort
    ksort($files);
    // find the last modification
    $reallyLastModified = end($files);

    foreach($files as $file) {
        $lastModified = date('F d Y, H:i:s',filemtime($file));
        if(strlen($file)-strpos($file,".swf")== 4){
           if ($file == $reallyLastModified) {
             // do stuff for the real last modified file
           }
           echo "<tr><td><input type=\"checkbox\" name=\"box[]\"></td><td><a href=\"$file\" target=\"_blank\">$file</a></td><td>$lastModified</td></tr>";
        }
    }
}

Not tested, but that's how to do it.

What you exactly wan't to do ?. To change Datatype of column you can simple use alter command as

ALTER TABLE table_name ALTER COLUMN LoginDate DateTime;

But remember there should valid Date only in this column however data-type is nvarchar.

If you wan't to convert data type while fetching data then you can use CONVERT function as,

CONVERT(data_type(length),expression,style)

eg:

SELECT CONVERT(DateTime, loginDate, 6)

This will return 29 AUG 13. For details about CONVERT function you can visit ,

http://www.w3schools.com/sql/func_convert.asp.

Remember, Always use DataTime data type for DateTime column.

Thank You

You need to make sure and have the following:

#include <windows.h>

and not this:

#include "windows.h"

If that's not the problem, then check RichieHindle's response.

What about this ?

create table dbo.[Address]
(
Id int identity not null,
City nvarchar(255) not null,
Street nvarchar(255) not null,
CONSTRAINT PK_Address PRIMARY KEY (Id)
)

create table dbo.[Person]
(
Id int identity not null,
AddressId int not null,
FirstName nvarchar(255) not null,
LastName nvarchar(255) not null,
CONSTRAINT PK_Person PRIMARY KEY (Id),
CONSTRAINT FK_Person_Address FOREIGN KEY (AddressId) REFERENCES dbo.[Address] (Id)
)

I suggest, you use the MaskedTextBox: http://msdn.microsoft.com/en-us/library/system.windows.forms.maskedtextbox.aspx

You could try pprintjson.

Installation

$ pip3 install pprintjson

Usage

Pretty print JSON from a file using the pprintjson CLI.

$ pprintjson "./path/to/file.json"

Pretty print JSON from a stdin using the pprintjson CLI.

$ echo '{ "a": 1, "b": "string", "c": true }' | pprintjson

Pretty print JSON from a string using the pprintjson CLI.

$ pprintjson -c '{ "a": 1, "b": "string", "c": true }'

Pretty print JSON from a string with an indent of 1.

$ pprintjson -c '{ "a": 1, "b": "string", "c": true }' -i 1

Pretty print JSON from a string and save output to a file output.json.

$ pprintjson -c '{ "a": 1, "b": "string", "c": true }' -o ./output.json

Output

With the forcats package from the tidyverse this is easy, too.

mutate(dat, x = fct_recode(x, "B" = "A"))

1. According to composer's manual:

   require-dev (root-only)

   Lists packages required for developing this package, or running tests, etc. The dev requirements of the root package are installed by default. Both install or update support the --no-dev option that prevents dev dependencies from being installed.

   So running composer install will also download the development dependencies.

2. The reason is actually quite simple. When contributing to a specific library you may want to run test suites or other develop tools (e.g. symfony). But if you install this library to a project, those development dependencies may not be required: not every project requires a test runner.

For some git-commands you can specify --verbose,

git 'command' --verbose

or

git 'command' -v.

Make sure the switch is after the actual git command. Otherwise - it won't work!

Also useful:

git 'command' --dry-run 

You have two options:

• FLUSHDB - clears currently active database
• FLUSHALL - clears all the existing databases

I've knocked up a MaxOrDefault extension method. There's not much to it but its presence in Intellisense is a useful reminder that Max on an empty sequence will cause an exception. Additionally, the method allows the default to be specified if required.

    public static TResult MaxOrDefault<TSource, TResult>(this 
    IQueryable<TSource> source, Expression<Func<TSource, TResult?>> selector,
    TResult defaultValue = default (TResult)) where TResult : struct
    {
        return source.Max(selector) ?? defaultValue;
    }

In ES6:

let myObj   = {myFn : function() {}, tamato: true};
let allKeys = Object.keys(myObj);
let fnKeys  = allKeys.filter(key => typeof myObj[key] == 'function');
console.log(fnKeys);
// output: ["myFn"]

UPDATE: (5 years later)

Note: If you decide to use Kappa Architecture (Event Sourcing + CQRS), then you do not need updated date at all. Since your data is an immutable, append-only event log, you only ever need event created date. Similar to the Lambda Architecture, described below. Then your application state is a projection of the event log (derived data). If you receive a subsequent event about existing entity, then you'll use that event's created date as updated date for your entity. This is a commonly used (and commonly misunderstood) practice in miceroservice systems.

UPDATE: (4 years later)

If you use ObjectId as your _id field (which is usually the case), then all you need to do is:

let document = {
  updatedAt: new Date(),
}

Check my original answer below on how to get the created timestamp from the _id field. If you need to use IDs from external system, then check Roman Rhrn Nesterov's answer.

UPDATE: (2.5 years later)

You can now use the #timestamps option with mongoose version >= 4.0.

let ItemSchema = new Schema({
  name: { type: String, required: true, trim: true }
},
{
  timestamps: true
});

If set timestamps, mongoose assigns createdAt and updatedAt fields to your schema, the type assigned is Date.

You can also specify the timestamp fileds' names:

timestamps: { createdAt: 'created_at', updatedAt: 'updated_at' }

Note: If you are working on a big application with critical data you should reconsider updating your documents. I would advise you to work with immutable, append-only data (lambda architecture). What this means is that you only ever allow inserts. Updates and deletes should not be allowed! If you would like to "delete" a record, you could easily insert a new version of the document with some timestamp/version filed and then set a deleted field to true. Similarly if you want to update a document – you create a new one with the appropriate fields updated and the rest of the fields copied over.Then in order to query this document you would get the one with the newest timestamp or the highest version which is not "deleted" (the deleted field is undefined or false`).

Data immutability ensures that your data is debuggable – you can trace the history of every document. You can also rollback to previous version of a document if something goes wrong. If you go with such an architecture ObjectId.getTimestamp() is all you need, and it is not Mongoose dependent.

ORIGINAL ANSWER:

If you are using ObjectId as your identity field you don't need created_at field. ObjectIds have a method called getTimestamp().

ObjectId("507c7f79bcf86cd7994f6c0e").getTimestamp()

This will return the following output:

ISODate("2012-10-15T21:26:17Z")

More info here How do I extract the created date out of a Mongo ObjectID

In order to add updated_at filed you need to use this:

var ArticleSchema = new Schema({
  updated_at: { type: Date }
  // rest of the fields go here
});

ArticleSchema.pre('save', function(next) {
  this.updated_at = Date.now();
  next();
});

For those of you using Centos (and perhaps other linux distibutions), you need to make sure that its FW (iptables) allows for port 80 or any other port you want.

See here on how to completely disable it (for testing purposes only!). And here for specific rules

Came across this looking for something else. While the post looks fairly old, the easiest solution in bash is illustrated below (at least bash 4) using set -- "${@:#}" where # is the starting number of the array element we want to preserve forward:

    #!/bin/bash

    someVar="${1}"
    someOtherVar="${2}"
    set -- "${@:3}"
    input=${@}

    [[ "${input[*],,}" == *"someword"* ]] && someNewVar="trigger"

    echo -e "${someVar}\n${someOtherVar}\n${someNewVar}\n\n${@}"

Basically, the set -- "${@:3}" just pops off the first two elements in the array like perl's shift and preserves all remaining elements including the third. I suspect there's a way to pop off the last elements as well.

Yes, we can run docker in docker, we'll need to attach the unix sockeet "/var/run/docker.sock" on which the docker daemon listens by default as volume to the parent docker using "-v /var/run/docker.sock:/var/run/docker.sock". Sometimes, permissions issues may arise for docker daemon socket for which you can write "sudo chmod 757 /var/run/docker.sock".

And also it would require to run the docker in privileged mode, so the commands would be:

sudo chmod 757 /var/run/docker.sock

docker run --privileged=true -v /var/run/docker.sock:/var/run/docker.sock -it ...

Whilst the accepted answer works and is good for Linq to Objects it bugged me that the SQL query isn't just a straight Left Outer Join.

The following code relies on the LinkKit Project that allows you to pass expressions and invoke them to your query.

static IQueryable<TResult> LeftOuterJoin<TSource,TInner, TKey, TResult>(
     this IQueryable<TSource> source, 
     IQueryable<TInner> inner, 
     Expression<Func<TSource,TKey>> sourceKey, 
     Expression<Func<TInner,TKey>> innerKey, 
     Expression<Func<TSource, TInner, TResult>> result
    ) {
    return from a in source.AsExpandable()
            join b in inner on sourceKey.Invoke(a) equals innerKey.Invoke(b) into c
            from d in c.DefaultIfEmpty()
            select result.Invoke(a,d);
}

It can be used as follows

Table1.LeftOuterJoin(Table2, x => x.Key1, x => x.Key2, (x,y) => new { x,y});

Markup

<select id="my_select">
    <option value="1">First</option>
    <option value="2">Second</option>
    <option value="3">Third</option>
</select>

jQuery

var my_value = 2;
$('#my_select option').each(function(){
    var $this = $(this); // cache this jQuery object to avoid overhead

    if ($this.val() == my_value) { // if this option's value is equal to our value
        $this.prop('selected', true); // select this option
        return false; // break the loop, no need to look further
    }
});

Demo

If the resource is showing and is a view, you can also capture it. Like a screenshot:

View rootView = ((View) findViewById(R.id.yourView)).getRootView();
rootView.setDrawingCacheEnabled(true);
rootView.layout(0, 0, rootView.getWidth(), rootView.getHeight());
rootView.buildDrawingCache();

Bitmap bm = Bitmap.createBitmap(rootView.getDrawingCache());

rootView.setDrawingCacheEnabled(false);

This actually grabs the whole layout but you can alter as you wish.

Try like this.

var hostname = window.location.origin

If the URL is "http://example.com/path" then you will get  "http://example.com" as the result.

This won't work for local domains

When you have URL like "https://localhost/MyProposal/MyDir/MyTestPage.aspx" 
and your virtual directory path is "https://localhost/MyProposal/" 
In such cases, you will get "https://localhost".

Even though this post is outdated, collection.remove is deprecated! collection.delete_one should be used instead!

You can do this in very simple way using size property of angular modal.

var modal = $modal.open({
                    templateUrl: "/partials/welcome",
                    controller: "welcomeCtrl",
                    backdrop: "static",
                    scope: $scope,
                    size:'lg' // you can try different width like 'sm', 'md'
                });

If you do a lot with timing, I can recommend this little (20 line) context manager:

• https://github.com/brouberol/timer-context-manager

You code could look like this then:

#!/usr/bin/env python
# coding: utf-8

from timer import Timer

if __name__ == '__main__':
    a, record = None, []
    while not a == '':
        with Timer() as t: # everything in the block will be timed
            a = input('Type: ')
        record.append(t.elapsed_s)
    # drop the last item (makes a copy of the list):
    record = record[:-1] 
    # or just delete it:
    # del record[-1]

Just for reference, here's the content of the Timer context manager in full:

from timeit import default_timer

class Timer(object):
    """ A timer as a context manager. """

    def __init__(self):
        self.timer = default_timer
        # measures wall clock time, not CPU time!
        # On Unix systems, it corresponds to time.time
        # On Windows systems, it corresponds to time.clock

    def __enter__(self):
        self.start = self.timer() # measure start time
        return self

    def __exit__(self, exc_type, exc_value, exc_traceback):
        self.end = self.timer() # measure end time
        self.elapsed_s = self.end - self.start # elapsed time, in seconds
        self.elapsed_ms = self.elapsed_s * 1000  # elapsed time, in milliseconds

I know this is a very old question but I post this solution in case it helps somebody. I recently met this problem and google led me here. The answer here helps me to understand the problem but there are still issues due to my parameter combination. What eventually solves my problem is curl to C# converter. It is a very powerful tool and supports most of the parameters for Curl. The code it generates is almost immediately runnable.

One of the way to enable cross domain request on local chrome browser :

1. Create a short cut of google chrome.
2. Properties -> append "--disable-web-security --user-data-dir" at the end of target.
3. Close or kill all process of google chrome.
4. Restart and hit the UI url.

Now UI and API running on different ports will be able to work together. I hope this helps.

If you are looking for an example of Cross-domain request . I'll put it in fragments for you to get enough idea.

        this.userService.changeUser(this.userModel);
        this.router.navigate(['/home']);
      }

user.ts: model.

export class User {

constructor(
    public  name : String,

Spring Webservice.

package com.rest;

import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

@RestController
// This annotation opens door for cross-domain(Cross-origin resource sharing (CORS)) from any host
@CrossOrigin(origins="*") 
public class MainController {

     @RequestMapping(value="/login", method=RequestMethod.POST)
     public User validUser(@RequestBody User user){


         BaseResponse response = new BaseResponse();

         if(user.getName().equalsIgnoreCase("shaz") && user.getPwd().equals("pwd")){

             user.setLoggedIn(true);
         }
         else{

             user.setLoggedIn(false);

         }
         return user;

     }
}

Now when you pass name as "shaz" and pwd as "pwd" in the form and hit submit,it gets validated from the SpringWebService and the loggedIn flag is set to true and the user entity is returned in response. Based on the loggedIn status from response,the user is redirected to home page or an error is thrown.

Note: I have not shared the complete setup and code

Refer this: https://shahbaazdesk.wordpress.com/2018/04/03/angular5-with-spring-webservice/

I recommend using the HTML <base> element:

<head>
    <base href="http://www.example.com/default/">
    <link rel="stylesheet" href="style.css" />
    <script src="script.js"></script>
</head>

In this example, the stylesheet is located in http://www.example.com/default/style.css, the script in http://www.example.com/default/script.js. The advantage of <base> over / is that it is more flexible. Your whole website can be located in a subdirectory of a domain, and you can easily alter the default directory of your website.

You can do this using Input.setSelectionRange, part of the Range API for interacting with text selections and the text cursor:

var searchInput = $('#Search');

// Multiply by 2 to ensure the cursor always ends up at the end;
// Opera sometimes sees a carriage return as 2 characters.
var strLength = searchInput.val().length * 2;

searchInput.focus();
searchInput[0].setSelectionRange(strLength, strLength);

Demo: Fiddle

What worked for me is the following:

Switch to the needed branch:

git checkout -b BranchName

And then I pulled the "master" by:

git pull origin master

There are scenarios in wich you cannot use bc becouse it might simply not be present, like in some cut down versions of busybox or embedded systems. In any case limiting outer dependencies is always a good thing to do so you can always add zeroes to the number being divided by (numerator), that is the same as multiplying by a power of 10 (you should choose a power of 10 according to the precision you need), that will make the division output an integer number. Once you have that integer treat it as a string and position the decimal point (moving it from right to left) a number of times equal to the power of ten you multiplied the numerator by. This is a simple way of obtaining float results by using only integer numbers.

I had this same error showing. When I replaced jQuery selector with normal JavaScript, the error was fixed.

var this_id = $(this).attr('id');

Replace:

getComputedStyle( $('#'+this_id)[0], "")

With:

getComputedStyle( document.getElementById(this_id), "")

This one helped me,

res.format({
        json:function(){
                            var responseData    = {};
                            responseData['status'] = 200;
                            responseData['outputPath']  = outputDirectoryPath;
                            responseData['sourcePath']  = url;
                            responseData['message'] = 'Scraping of requested resource initiated.';
                            responseData['logfile'] = logFileName;
                            res.json(JSON.stringify(responseData));
                        }
    });

You could fill the C Column with variations on the following formula:

=IF(ISERROR(MATCH(A1,$B:$B,0)),"",A1)

Then C would only contain values that were in A and C.

Replace(@"\""", "")

You have to use double-doublequotes to escape double-quotes within a verbatim string.

you to restart services PostgreSQL from task manager click ctrl+alt+delete then chose services the postgresql-[version] chose the option to run automatically then start and apply ->ok

sudo nano /etc/redis/redis.conf 

find and uncomment line # requirepass foobared, then restart server

now you password is foobared

The compiler cannot guess what should be passed for the base constructor argument. You have to do it explicitly:

public class child : parent {
    public child(int i) : base(i) {
        Console.WriteLine("child");
    }
}

I found a nice solution here:

isiterable = lambda obj: isinstance(obj, basestring) \
    or getattr(obj, '__iter__', False)

By referring to https://jwt.io/ you can find jwt implementations in many languages including java. Also the site provide some comparison between these implementation (the algorithms they support and ....).

For java these are mentioned libraries:

• https://github.com/jwtk/jjwt
• https://github.com/auth0/java-jwt ( A tutorial at https://auth0.com/docs/server-apis/java)
• https://bitbucket.org/b_c/jose4j
• https://bitbucket.org/connect2id/nimbus-jose-jwt

You can do this way:

var preval = $('#my_select').val(); // get the def value

$("#reset").on("click", function () {
   $('#my_select option[value*="' + preval + '"]').prop('selected', true);
});

checkout this fiddle

take a var which holds the default loaded value before change event then get the option with the attribute selector of value with holds the var value set the property to selected.

git push -u upstream/dev

You just need to set the table cell padding to zero. Here's a jsfiddle (using Bootstrap 2.3.2) with your code slightly modified:

http://jsfiddle.net/marciowerner/fhjgn7b5/4/

The javascript is optional and only needed if you want to use a cell padding other than zero.

$('.collapse').on('show.bs.collapse', function() {_x000D_
  $(this).parent().removeClass("zeroPadding");_x000D_
});_x000D_
_x000D_
$('.collapse').on('hide.bs.collapse', function() {_x000D_
  $(this).parent().addClass("zeroPadding");_x000D_
});

.zeroPadding {_x000D_
  padding: 0 !important;_x000D_
}

  <table class="table table-bordered table-striped">_x000D_
    <tr>_x000D_
      <td>_x000D_
        <button type="button" class="btn" data-toggle="collapse" data-target="#collapseme">Click to expand</button>_x000D_
      </td>_x000D_
    </tr>_x000D_
    <tr>_x000D_
      <td class="zeroPadding">_x000D_
        <div class="collapse out" id="collapseme">Should be collapsed</div>_x000D_

  </table>_x000D_
</body>

So maybe you want to have this in your index.html to load the library, script, and initialize the app with a view:

<html>
  <body ng-app="yourApp">
    <div class="span12">
      <div ng-view=""></div>
    </div>
    <script src="http://code.angularjs.org/1.2.0-rc.2/angular.js"></script>
    <script src="script.js"></script>
  </body>
</html>

Then yourView.html could just be:

<div>
  <h1>{{ stuff.h1 }}</h1>
  <p>{{ stuff.content }}</p>
</div>

scripts.js could have your controller with data $scope'd to it.

angular.module('yourApp')
    .controller('YourCtrl', function ($scope) {
      $scope.stuff = {
        'h1':'Title',
        'content':"A paragraph..."
      };
    });

Lastly, you'll have to config routes and assign the controller to view for it's $scope (i.e. your data object)

angular.module('yourApp', [])
.config(function ($routeProvider) {
  $routeProvider
    .when('/', {
      templateUrl: 'views/yourView.html',
      controller: 'YourCtrl'
    });
});

I haven't tested this, sorry if there's a bug but I think this is the Angularish way to get data

Echoing Data If It Exists

Sometimes you may wish to echo a variable, but you aren't sure if the variable has been set. We can express this in verbose PHP code like so:

{{ isset($name) ? $name : 'Default' }}

However, instead of writing a ternary statement, Blade provides you with the following convenient short-cut:

{{ $name or 'Default' }}

In this example, if the $name variable exists, its value will be displayed. However, if it does not exist, the word Default will be displayed.

From https://laravel.com/docs/5.4/blade#displaying-data

The difference between starting an Activity from a Fragment and an Activity is how you get the context, because in both cases it has to be an activity.

From an activity: The context is the current activity (this)

Intent intent = new Intent(this, NewActivity.class);
startActivity(intent);

From a fragment: The context is the parent activity (getActivity()). Notice, that the fragment itself can start the activity via startActivity(), this is not necessary to be done from the activity.

Intent intent = new Intent(getActivity(), NewActivity.class);
startActivity(intent);

if [ ${foo:+1} ]
then
    echo "yes"
fi

prints yes if the variable is set. ${foo:+1} will return 1 when the variable is set, otherwise it will return empty string.

Just an idea, if you know the categories, as small, medium, and large mentioned above...

At the bottom of the sheet, make 3 rows that only say small, medium, and large, change the font to white, and then sort so that it alphabetizes, placing a blank row between each section.

At some point, I suppose you will add your programatically created LinearLayout to some root layout that you defined in .xml. This is just a suggestion of mine and probably one of many solutions, but it works: Simply set an ID for the programatically created layout, and add it to the root layout that you defined in .xml, and then use the set ID to add the Fragment.

It could look like this:

LinearLayout rowLayout = new LinearLayout();
rowLayout.setId(whateveryouwantasid);
// add rowLayout to the root layout somewhere here

FragmentManager fragMan = getFragmentManager();
FragmentTransaction fragTransaction = fragMan.beginTransaction();   

Fragment myFrag = new ImageFragment();
fragTransaction.add(rowLayout.getId(), myFrag , "fragment" + fragCount);
fragTransaction.commit();

Simply choose whatever Integer value you want for the ID:

rowLayout.setId(12345);

If you are using the above line of code not just once, it would probably be smart to figure out a way to create unique-IDs, in order to avoid duplicates.

UPDATE:

Here is the full code of how it should be done: (this code is tested and works) I am adding two Fragments to a LinearLayout with horizontal orientation, resulting in the Fragments being aligned next to each other. Please also be aware, that I used a fixed height and width of 200dp, so that one Fragment does not use the full screen as it would with "match_parent".

MainActivity.java:

public class MainActivity extends Activity {

    @SuppressLint("NewApi")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);     

        LinearLayout fragContainer = (LinearLayout) findViewById(R.id.llFragmentContainer);

        LinearLayout ll = new LinearLayout(this);
        ll.setOrientation(LinearLayout.HORIZONTAL);

        ll.setId(12345);

        getFragmentManager().beginTransaction().add(ll.getId(), TestFragment.newInstance("I am frag 1"), "someTag1").commit();
        getFragmentManager().beginTransaction().add(ll.getId(), TestFragment.newInstance("I am frag 2"), "someTag2").commit();

        fragContainer.addView(ll);
    }
}

TestFragment.java:

public class TestFragment extends Fragment {

    public static TestFragment newInstance(String text) {

        TestFragment f = new TestFragment();

        Bundle b = new Bundle();
        b.putString("text", text);
        f.setArguments(b);
        return f;
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

        View v =  inflater.inflate(R.layout.fragment, container, false);

        ((TextView) v.findViewById(R.id.tvFragText)).setText(getArguments().getString("text"));     
        return v;
    }
}

activity_main.xml:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/rlMain"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="5dp"
    tools:context=".MainActivity" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/hello_world" />

    <LinearLayout
        android:id="@+id/llFragmentContainer"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_alignLeft="@+id/textView1"
        android:layout_below="@+id/textView1"
        android:layout_marginTop="19dp"
        android:orientation="vertical" >
    </LinearLayout>
</RelativeLayout>

fragment.xml:

  <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="200dp"
    android:layout_height="200dp" >

    <TextView
        android:id="@+id/tvFragText"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:text="" />

</RelativeLayout>

And this is the result of the above code: (the two Fragments are aligned next to each other)

I too have been through this pain - if the query is dynamically generated (e.g. Hibernate Criteria) then I couldn't find a practical way to do it.

The good news for me was that I was only investigating union to solve a performance problem when using an 'or' in an Oracle database.

The solution Patrick posted (combining the results programmatically using a set) while ugly (especially since I wanted to do results paging as well) was adequate for me.

Take the number 123.456789

• As an integer, this number would be 123
• As a fixed point (2), this number would be 123.46 (Assuming you rounded it up)
• As a floating point, this number would be 123.456789

Floating point lets you represent most every number with a great deal of precision. Fixed is less precise, but simpler for the computer..

This is a classic difficulty in LaTeX.

The problem is how to do layout with floats (figures and tables, an similar objects) and footnotes. In particular, it is hard to pick a place for a float with certainty that making room for the associated footnotes won't cause trouble. So the standard tabular and figure environments don't even try.

What can you do:

1. Fake it. Just put a hardcoded vertical skip at the bottom of the caption and then write the footnote yourself (use \footnotesize for the size). You also have to manage the symbols or number yourself with \footnotemark. Simple, but not very attractive, and the footnote does not appear at the bottom of the page.
2. Use the tabularx, longtable, threeparttable[x] (kudos to Joseph) or ctable which support this behavior.
3. Manage it by hand. Use [h!] (or [H] with the float package) to control where the float will appear, and \footnotetext on the same page to put the footnote where you want it. Again, use \footnotemark to install the symbol. Fragile and requires hand-tooling every instance.
4. The footnotes package provides the savenote environment, which can be used to do this.
5. Minipage it (code stolen outright, and read the disclaimer about long caption texts in that case):

    \begin{figure}
      \begin{minipage}{\textwidth}
        ...
        \caption[Caption for LOF]%
          {Real caption\footnote{blah}}
      \end{minipage}
    \end{figure}

Another reason this can happen is if you send the wrong appId. This can happen in early development if you have a development app and a production app. If you hard-code the appId for dev and push to prod, this will show up.

There are three ways:

• Use SFTP plugin (commercial) http://wbond.net/sublime_packages/sftp - I personally recommend this, as after settings public SSH keys with passphrase it is safe, easy and worth every penny http://opensourcehacker.com/2012/10/24/ssh-key-and-passwordless-login-basics-for-developers/

• Mount the remote as local file system using osxfuse and sshfs as mentioned in the comments. This might be little difficult, depending on OSX version and your skills with UNIX file systems.

• Hack together something like rmate which does file editing over remote tunneling using some kind of a local daemon (very difficult, cumbersome, but sudo compatible) http://blog.macromates.com/2011/mate-and-rmate/

Also, in theory, you can install X11 on the remote server and run Sublime there over VNC or X11 forwarding, but there would be no point doing this.

I feel like none of the answers have crystallized why mapDispatchToProps is useful.

This can really only be answered in the context of the container-component pattern, which I found best understood by first reading:Container Components then Usage with React.

In a nutshell, your components are supposed to be concerned only with displaying stuff. The only place they are supposed to get information from is their props.

Separated from "displaying stuff" (components) is:

• how you get the stuff to display,
• and how you handle events.

That is what containers are for.

Therefore, a "well designed" component in the pattern look like this:

class FancyAlerter extends Component {
    sendAlert = () => {
        this.props.sendTheAlert()
    }

    render() {
        <div>
          <h1>Today's Fancy Alert is {this.props.fancyInfo}</h1>
          <Button onClick={sendAlert}/>
        </div>
     }
}

See how this component gets the info it displays from props (which came from the redux store via mapStateToProps) and it also gets its action function from its props: sendTheAlert().

That's where mapDispatchToProps comes in: in the corresponding container

// FancyButtonContainer.js

function mapDispatchToProps(dispatch) {
    return({
        sendTheAlert: () => {dispatch(ALERT_ACTION)}
    })
}

function mapStateToProps(state) {
    return({fancyInfo: "Fancy this:" + state.currentFunnyString})
}

export const FancyButtonContainer = connect(
    mapStateToProps, mapDispatchToProps)(
    FancyAlerter
)

I wonder if you can see, now that it's the container 1 that knows about redux and dispatch and store and state and ... stuff.

The component in the pattern, FancyAlerter, which does the rendering doesn't need to know about any of that stuff: it gets its method to call at onClick of the button, via its props.

And ... mapDispatchToProps was the useful means that redux provides to let the container easily pass that function into the wrapped component on its props.

All this looks very like the todo example in docs, and another answer here, but I have tried to cast it in the light of the pattern to emphasize why.

(Note: you can't use mapStateToProps for the same purpose as mapDispatchToProps for the basic reason that you don't have access to dispatch inside mapStateToProp. So you couldn't use mapStateToProps to give the wrapped component a method that uses dispatch.

I don't know why they chose to break it into two mapping functions - it might have been tidier to have mapToProps(state, dispatch, props) IE one function to do both!

1 Note that I deliberately explicitly named the container FancyButtonContainer, to highlight that it is a "thing" - the identity (and hence existence!) of the container as "a thing" is sometimes lost in the shorthand

export default connect(...) ????????????

syntax that is shown in most examples

java.lang.NoSuchMethodError: javax.servlet.ServletContext.getContextPath()Ljava/lang/String;

That method was added in Servlet 2.5.

So this problem can have at least 3 causes:

1. The servlet container does not support Servlet 2.5.
2. The web.xml is not declared conform Servlet 2.5 or newer.
3. The webapp's runtime classpath is littered with servlet container specific JAR files of a different servlet container make/version which does not support Servlet 2.5.

To solve it,

1. Make sure that your servlet container supports at least Servlet 2.5. That are at least Tomcat 6, Glassfish 2, JBoss AS 4.1, etcetera. Tomcat 5.5 for example supports at highest Servlet 2.4. If you can't upgrade Tomcat, then you'd need to downgrade Spring to a Servlet 2.4 compatible version.
2. Make sure that the root declaration of web.xml complies Servlet 2.5 (or newer, at least the highest whatever your target runtime supports). For an example, see also somewhere halfway our servlets wiki page.
3. Make sure that you don't have any servlet container specific libraries like servlet-api.jar or j2ee.jar in /WEB-INF/lib or even worse, the JRE/lib or JRE/lib/ext. They do not belong there. This is a pretty common beginner's mistake in an attempt to circumvent compilation errors in an IDE, see also How do I import the javax.servlet API in my Eclipse project?.

Use minDate

var date = new Date();
var today = new Date(date.getFullYear(), date.getMonth(), date.getDate());

$('#date').datepicker({ 
    minDate: today
});

//Simple example code:

foreach (var item in YourCheckedListBox.CheckedItems)
{List<string>.Add(item);}

You are assigning to a function call:

invest(initial_amount,top_company(5,year,year+1)) = subsequent_amount

which is illegal in Python. The question is, what do you want to do? What does invest() do? I suppose it returns a value, namely what you're trying to use as subsequent_amount, right?

If so, then something like this should work:

amount = invest(amount,top_company(5,year,year+1),year)

childClass::customMethod() has different arguments, or a different access level (public/private/protected) than parentClass::customMethod().

In case of NULL columns it is better to use IF clause like this which combine the two functions of : CONCAT and COALESCE and uses special chars between the columns in result like space or '_'

SELECT FirstName , LastName , 
IF(FirstName IS NULL AND LastName IS NULL, NULL,' _ ',CONCAT(COALESCE(FirstName ,''), COALESCE(LastName ,''))) 
AS Contact_Phone FROM   TABLE1

Use the in keyword without is.

if "x" in dog:
    print "Yes!"

If you'd like to check for the non-existence of a character, use not in:

if "x" not in dog:
    print "No!"

python_test.py

import subprocess
a = subprocess.check_output("batch_1.bat")
print a

This gives output from batch file to be print on the python IDLE/running console. So in batch file you can echo the result in each step to debug the issue. This is also useful in automation when there is an error happening in the batch call, to understand and locate the error easily.(put "echo off" in batch file beginning to avoid printing everything)

batch_1.bat

echo off    
echo "Hello World" 
md newdir 
echo "made new directory"

I have SingleChildScrollView as a parent, and one Column Widget and then List View Widget as last child.

Adding these properties in List View Worked for me.

  physics: NeverScrollableScrollPhysics(),
  shrinkWrap: true,
  scrollDirection: Axis.vertical,

That's another solution (Spring Security 3):

public String getLoggedUser() throws Exception {
    String name = SecurityContextHolder.getContext().getAuthentication().getName();
    return (!name.equals("anonymousUser")) ? name : null;
}

I was trying these examples without success. Apparently other stylesheets on the page were setting default font sizes for different tags. If you adjust the ui-datepicker you are changing a div. If you change a div you need to make sure the contents of that div inherit that size. This is what finally worked for me:

<style type="text/css">
.ui-datepicker-calendar tr, .ui-datepicker-calendar td, .ui-datepicker-calendar td a, .ui-datepicker-calendar th{font-size:inherit;}
div.ui-datepicker{font-size:16px;width:inherit;height:inherit;}
.ui-datepicker-title span{font-size:16px;}
</style>

Good luck!

Not this one. Use this:

Menu File → Preferences → Workspace Settings, "editor.formatOnType": true

You can always use the

echo "Column1`tColumn2`tColumn3..." >> results.csv

You will need to put "`t" between the columns to separates the variables into their own column. Here is the way I wrote my script:

echo "Host`tState" >> results.csv
$names = Get-Content "hostlist.txt"
foreach ($name in $names) {
    $count = 0
    $count2 = 13490

    if ( Test-Connection -ComputerName $name -Count 1 -ErrorAction SilentlyContinue ) {
        echo "$name`tUp" >> results.csv
    }
    else {
        echo "$name`tDown" >> results.csv
    }

    $count++
    Write-Progress -Activity "Gathering Information" -status "Pinging Hosts..." -percentComplete ($count / $count2 *100)

}

This is the easiest way to me. The output I get is :

Host|State
----------
H1  |Up
H2  |UP
H3  |Down

You can play around with the look, but that's the basic idea. The $count is just a progress bar if you want to spice up the look

You could use animation like this:

-webkit-animation: spin 1s infinite linear;

@-webkit-keyframes spin {
    0%   {-webkit-transform: rotate(0deg)}
    100% {-webkit-transform: rotate(360deg)}
}

In Swift 2.0:

UIApplication.sharedApplication().openURL(NSURL(string: "http://stackoverflow.com")!)

There is a difference between . and text(), but this difference might not surface because of your input document.

If your input document looked like (the simplest document one can imagine given your XPath expressions)

Example 1

<html>
  <a>Ask Question</a>
</html>

Then //a[text()="Ask Question"] and //a[.="Ask Question"] indeed return exactly the same result. But consider a different input document that looks like

Example 2

<html>
  <a>Ask Question<other/>
  </a>
</html>

where the a element also has a child element other that follows immediately after "Ask Question". Given this second input document, //a[text()="Ask Question"] still returns the a element, while //a[.="Ask Question"] does not return anything!

This is because the meaning of the two predicates (everything between [ and ]) is different. [text()="Ask Question"] actually means: return true if any of the text nodes of an element contains exactly the text "Ask Question". On the other hand, [.="Ask Question"] means: return true if the string value of an element is identical to "Ask Question".

In the XPath model, text inside XML elements can be partitioned into a number of text nodes if other elements interfere with the text, as in Example 2 above. There, the other element is between "Ask Question" and a newline character that also counts as text content.

To make an even clearer example, consider as an input document:

Example 3

<a>Ask Question<other/>more text</a>

Here, the a element actually contains two text nodes, "Ask Question" and "more text", since both are direct children of a. You can test this by running //a/text() on this document, which will return (individual results separated by ----):

Ask Question
-----------------------
more text

So, in such a scenario, text() returns a set of individual nodes, while . in a predicate evaluates to the string concatenation of all text nodes. Again, you can test this claim with the path expression //a[.='Ask Questionmore text'] which will successfully return the a element.

Finally, keep in mind that some XPath functions can only take one single string as an input. As LarsH has pointed out in the comments, if such an XPath function (e.g. contains()) is given a sequence of nodes, it will only process the first node and silently ignore the rest.

Just a small addition to Jeff Bowman's excellent answer, as I found this question when searching for a solution to one of my own problems:

If a call to a method matches more than one mock's when trained calls, the order of the when calls is important, and should be from the most wider to the most specific. Starting from one of Jeff's examples:

when(foo.quux(anyInt(), anyInt())).thenReturn(true);
when(foo.quux(anyInt(), eq(5))).thenReturn(false);

is the order that ensures the (probably) desired result:

foo.quux(3 /*any int*/, 8 /*any other int than 5*/) //returns true
foo.quux(2 /*any int*/, 5) //returns false

If you inverse the when calls then the result would always be true.

In Python, a distinction between expressions and statements is rigidly enforced, in contrast to languages such as Common Lisp, Scheme, or Ruby.

Wikipedia

So by introducing such operators, you would break the expression/statement split.

For the same reason you can't write

if x = 0:
  y = 1

as you can in some other languages where such distinction is not preserved.

You can use == to compare with a zero value composite literal because all fields are comparable:

if (Session{}) == session  {
    fmt.Println("is zero value")
}

playground example

Because of a parsing ambiguity, parentheses are required around the composite literal in the if condition.

The use of == above applies to structs where all fields are comparable. If the struct contains a non-comparable field (slice, map or function), then the fields must be compared one by one to their zero values.

An alternative to comparing the entire value is to compare a field that must be set to a non-zero value in a valid session. For example, if the player id must be != "" in a valid session, use

if session.playerId == "" {
    fmt.Println("is zero value")
}

Youtube doesn't provide any option for an end time, but there alternative sites that provide this, like Tubechop. Otherwise try writing a function that either pauses video/skips to next when your when your video has played its desired duration.

OR: using the Youtube Javascript player API, you could do something like this:

function onPlayerStateChange(evt) {
    if (evt.data == YT.PlayerState.PLAYING && !done) {
        setTimeout(stopVideo, 6000);
        done = true;
    }
}

you have to match the input format of your date field to the required entity format which is yyyy/mm/dd

@mani's response is now slightly outdated as using catch-all '*' routes is no longer supported when using Vue 3 onward. If this is no longer working for you, try replacing the old catch-all path with

{ path: '/:pathMatch(.*)*', component: PathNotFound },

Essentially, you should be able to replace the '*' path with '/:pathMatch(.*)*' and be good to go!

Reason: Vue Router doesn't use path-to-regexp anymore, instead it implements its own parsing system that allows route ranking and enables dynamic routing. Since we usually add one single catch-all route per project, there is no big benefit in supporting a special syntax for *.

(from https://next.router.vuejs.org/guide/migration/#removed-star-or-catch-all-routes)

1. origin - This is a custom and most common name to point to remote.

$ git remote add origin https://github.com/git/git.git --- You will run this command to link your github project to origin. Here origin is user-defined. You can rename it by $ git remote rename old-name new-name

2. master - The default branch name in Git is master. For both remote and local computer.

3. origin/master - This is just a pointer to refer master branch in remote repo. Remember i said origin points to remote.

$ git fetch origin - Downloads objects and refs from remote repository to your local computer [origin/master]. That means it will not affect your local master branch unless you merge them using $ git merge origin/master. Remember to checkout the correct branch where you need to merge before run this command

Note: Fetched content is represented as a remote branch. Fetch gives you a chance to review changes before integrating them into your copy of the project. To show changes between yours and remote $git diff master..origin/master

create two Date objects and call valueOf() on both, then compare them.

JavaScript Date Object Reference

This is how I was able to trigger a button click when the page loads.

<li ng-repeat="a in array">
  <a class="button" id="btn" ng-click="function(a)" index="$index" on-load-clicker>
    {{a.name}}
  </a>
</li>

A simple directive that takes the index from the ng-repeat and uses a condition to call the first button in the index and click it when the page loads.

angular
    .module("myApp")
        .directive('onLoadClicker', function ($timeout) {
            return {
                restrict: 'A',
                scope: {
                    index: '=index'
                },
                link: function($scope, iElm) {
                    if ($scope.index == 0) {
                        $timeout(function() {

                            iElm.triggerHandler('click');

                        }, 0);
                    }
                }
            };
        });

This was the only way I was able to even trigger an auto click programmatically in the first place. angular.element(document.querySelector('#btn')).click(); Did not work from the controller so making this simple directive seems most effective if you are trying to run a click on page load and you can specify which button to click by passing in the index. I got help through this stack-overflow answer from another post reference: https://stackoverflow.com/a/26495541/4684183 onLoadClicker Directive.

The main (very interesting) difference for me is that:
"string" & Null -> "string"
while
"string" + Null -> Null

But that's probably more useful in database apps like Access.

onclick vs addEventListener. A matter of preference perhaps (where IE>9).

// Using closures
function onClickLink(e, index) {   
    alert(index);
    return false;
}

var div = document.getElementById('div');

for (var i = 0; i < 10; i++) {
    var link = document.createElement('a');

    link.setAttribute('href', '#');
    link.innerHTML = i + '';
    link.addEventListener('click', (function(e) {
        var index = i;
        return function(e) {
            return onClickLink(e, index);
        }
    })(), false);
    div.appendChild(link);
    div.appendChild(document.createElement('BR'));
}

How abut just using a plain data-* attribute, not as cool as a closure, but..

function onClickLink(e) {       
    alert(e.target.getAttribute('data-index'));
    return false;
}

var div = document.getElementById('div');

for (var i = 0; i < 10; i++) {
    var link = document.createElement('a');

    link.setAttribute('href', '#');
    link.setAttribute('data-index', i);
    link.innerHTML = i + ' Hello';        
    link.addEventListener('click', onClickLink, false);
    div.appendChild(link);
    div.appendChild(document.createElement('BR'));
}

// aspx.cs

// Load CheckBoxList selected items into ListBox

    int status = 1;
    foreach (ListItem  s in chklstStates.Items  )
    {
        if (s.Selected == true)
        {
            if (ListBox1.Items.Count == 0)
            {
                ListBox1.Items.Add(s.Text);

            }
            else
            {
                foreach (ListItem list in ListBox1.Items)
                {
                    if (list.Text == s.Text)
                    {
                        status = status * 0;

                    }
                    else
                    {
                        status = status * 1;
                    }
                }
                if (status == 0)
                { }
               else
                {
                    ListBox1.Items.Add(s.Text);
                }
                status = 1;

In the top level of the IIS Manager (above Sites), you should see the Application Pools tree node. Right click on "Application Pools", choose "Add Application Pool".

Give it a name, choose .NET Framework 4.0 and either Integrated or Classic mode.

When you add or edit a web site, your new application pools will now show up in the list.

To clear all rows that have data I use two variables like this. I like this because you can adjust it to a certain range of columns if you need to. Dim CRow As Integer Dim LastRow As Integer

CRow = 1
LastRow = Cells(Rows.Count, 3).End(xlUp).Row

Do Until CRow = LastRow + 1
    Cells(CRow, 1).Value = Empty
    Cells(CRow, 2).Value = Empty
    Cells(CRow, 3).Value = Empty
    Cells(CRow, 4).Value = Empty
    CRow = CRow + 1
Loop

It works for me with

logging.level.org.hibernate.SQL= DEBUG

logging.level.org.hibernate.type=TRACE

ssize_t is used for functions whose return value could either be a valid size, or a negative value to indicate an error. It is guaranteed to be able to store values at least in the range [-1, SSIZE_MAX] (SSIZE_MAX is system-dependent).

So you should use size_t whenever you mean to return a size in bytes, and ssize_t whenever you would return either a size in bytes or a (negative) error value.

My 2 cents:

I did notice that some singleton / static fields were reseted when my activity was destroyed. I noticed this on some low end 2.3 devices.

My case was very simple : I just have a private filed "init_done" and a static method "init" that I called from activity.onCreate(). I notice that the method init was re-executing itself on some re-creation of the activity.

While I cannot prove my affirmation, It may be related to WHEN the singleton/class was created/used first. When the activity get destroyed/recycled, it seem that all class that only this activity refer are recycled too.

I moved my instance of singleton to a sub class of Application. I acces them from the application instance. and, since then, did not notice the problem again.

I hope this can help someone.

I used the code below and it worked for me.

String email="";
    SqlDataReader reader=cmd.ExecuteReader();
    if(reader.Read()){
        email=reader["Email"].ToString();
    }

String To=email;

Change your main to:

public static void main(String[] args) {
    EchoServer echoServer = new EchoServer();
    echoServer.listen();
}

When you declare Object EchoServer0; you have a few mistakes.

1. EchoServer0 is of type Object, therefore it doesn't have the method listen().
2. You will also need to create an instance of it with new.
3. Another problem, this is only regarding naming conventions, you should call your variables starting by lower case letters, echoServer0 instead of EchoServer0. Uppercase names are usually for class names.
4. You should not create a variable with the same name as its class. It is confusing.

In case you need to convert a timeval struct (seconds, microseconds) containing UNIX time to DateTime without losing precision, this is how:

DateTime _epochTime = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc);
private DateTime UnixTimeToDateTime(Timeval unixTime)
{
    return _epochTime.AddTicks(
        unixTime.Seconds * TimeSpan.TicksPerSecond +
        unixTime.Microseconds * TimeSpan.TicksPerMillisecond/1000);
}

Figured I'd throw this on here since this seems to be most popular form of this question.

I ran a 100 year comparison on 3 of the most popular types of age funcs i could find for PHP and posted my results (as well as the functions) to my blog.

As you can see there, all 3 funcs preform well with just a slight difference on the 2nd function. My suggestion based on my results is to use the 3rd function unless you want to do something specific on a person's birthday, in which case the 1st function provides a simple way to do exactly that.

_{Found small issue with test, and another issue with 2nd method! Update coming to blog soon! For now, I'd take note, 2nd method is still most popular one I find online, and yet still the one I'm finding the most inaccuracies with!}

My suggestions after my 100 year review:

If you want something more elongated so that you can include occasions like birthdays and such:

function getAge($date) { // Y-m-d format
    $now = explode("-", date('Y-m-d'));
    $dob = explode("-", $date);
    $dif = $now[0] - $dob[0];
    if ($dob[1] > $now[1]) { // birthday month has not hit this year
        $dif -= 1;
    }
    elseif ($dob[1] == $now[1]) { // birthday month is this month, check day
        if ($dob[2] > $now[2]) {
            $dif -= 1;
        }
        elseif ($dob[2] == $now[2]) { // Happy Birthday!
            $dif = $dif." Happy Birthday!";
        };
    };
    return $dif;
}

getAge('1980-02-29');

But if you just simply want to know the age and nothing more, then:

function getAge($date) { // Y-m-d format
    return intval(substr(date('Ymd') - date('Ymd', strtotime($date)), 0, -4));
}

getAge('1980-02-29');

See BLOG

A key note about the strtotime method:

Note:

Dates in the m/d/y or d-m-y formats are disambiguated by looking at the 
separator between the various components: if the separator is a slash (/), 
then the American m/d/y is assumed; whereas if the separator is a dash (-) 
or a dot (.), then the European d-m-y format is assumed. If, however, the 
year is given in a two digit format and the separator is a dash (-, the date 
string is parsed as y-m-d.

To avoid potential ambiguity, it's best to use ISO 8601 (YYYY-MM-DD) dates or 
DateTime::createFromFormat() when possible.

If you want to check if an element is visible on the page, depending on the visibility of its parent, you can check if width and height of the element are both equal to 0.

jQuery

$element.width() === 0 && $element.height() === 0

Vanilla

element.clientWidth === 0 && element.clientHeight === 0

Or

element.offsetWidth === 0 && element.offsetHeight === 0

@Jon: Jon, are you saying using multiple where clauses e.g.

var query = from r in tempData.AsEnumerable()
            where r.Field<string>("UserName") != "XXXX" 
            where r.Field<string>("UserName") != "YYYY"
            select r;

is more restictive than using

var query = from r in tempData.AsEnumerable()
            where r.Field<string>("UserName") != "XXXX" && r.Field<string>("UserName") != "YYYY"
            select r;

I think they are equivalent as far as the result goes.

However, I haven't tested, if using multiple where in the first example cause in 2 subqueries, i.e. .Where(r=>r.UserName!="XXXX").Where(r=>r.UserName!="YYYY) or the LINQ translator is smart enought to execute .Where(r=>r.UserName!="XXXX" && r.UsernName!="YYYY")

You should remove navbar-fixed-top class otherwise navbar stays fixed on top of page where you want logo.

If you want to place logo inside navbar:

Navbar height (set in @navbarHeight LESS variable) is 40px by default. Your logo has to fit inside or you have to make navbar higher first.

Then use brand class:

<div class="navbar navbar-fixed-top">
  <div class="navbar-inner">
    <div class="container">
      <a href="/" class="brand"><img alt="" src="/logo.gif" /></a>
    </div>
  </div>
</div>

If your logo is higher than 20px, you have to fix stylesheets as well.

If you do that in LESS:

.navbar .brand {
  @elementHeight: 32px;
  padding: ((@navbarHeight - @elementHeight) / 2 - 2) 20px ((@navbarHeight - @elementHeight) / 2 + 2);
}

@elementHeight should be set to your image height.

Padding calculation is taken from Twitter Bootstrap LESS - https://github.com/twitter/bootstrap/blob/v2.0.4/less/navbar.less#L51-52

Alternatively you can calculate padding values yourself and use pure CSS.

This works for Twitter Bootstrap versions 2.0.x, should work in 2.1 as well, but padding calculation was changed a bit: https://github.com/twitter/bootstrap/blob/v2.1.0/less/navbar.less#L50

Yes you can.

See the code from the following thread from 2007: PDF within a DIV

<div>
    <object data="test.pdf" type="application/pdf" width="300" height="200">
        alt : <a href="test.pdf">test.pdf</a>
    </object>
</div>

It uses <object>, which can be styled with CSS, and so you can float them, give them borders, etc.

(In the end, I edited my pdf files to remove large borders and converted them to jpg images.)

I think you need to set symbreaks = FALSE That should allow for asymmetrical color scales.

If your project doesn't have an upstream branch, that is if this is the very first time the remote repository is going to know about the branch created in your local repository the following command should work.

git push --set-upstream origin <branch-name>

If you use different version of play services libraries, you will get this error.

For example, below entries in build.gradle file cause the error as versions are different.

implementation 'com.google.android.gms:play-services-maps:11.4.2'
implementation 'com.google.android.gms:play-services-location:11.6.0'

To fix the issue use same versions.

implementation 'com.google.android.gms:play-services-maps:11.6.0'
implementation 'com.google.android.gms:play-services-location:11.6.0'

If you're using Python3.x input will return a string,so you should use int method to convert string to integer.

Python3 Input

If the prompt argument is present, it is written to standard output without a trailing newline. The function then reads a line from input, converts it to a string (stripping a trailing newline), and returns that. When EOF is read, EOFError is raised.

By the way,it's a good way to use try catch if you want to convert string to int:

try:
  i = int(s)
except ValueError as err:
  pass 

Hope this helps.

Try giving your divs a width of 100%.

I did the below changes and works fine for me.

Just add the attribute <iframe src="URL" target="_parent" />

_parent: this would open embedded page in same window.

_blank: In different tab

There are many ways. Here are at least five:

/*
 * An example of converting std::string to (const)char* using five
 * different methods. Error checking is emitted for simplicity.
 *
 * Compile and run example (using gcc on Unix-like systems):

 *  $ g++ -Wall -pedantic -o test ./test.cpp
 *  $ ./test
 *  Original string (0x7fe3294039f8): hello

    // This is the initial C++ string.
    s0 = "hello";

    // Method #1: Just use "c_str()" method to obtain a pointer to a

    // the memory is invalidated.
    s2 = (char *)alloca(s0.size() + 1);
    memcpy(s2, s0.c_str(), s0.size() + 1);

    // Method #3: Allocate memory dynamically and copy the content of the

    // Release memory...
    free(s3);
    delete [] s4;
    free(s5);
}

problem is with dos line ending. Following will convert it for unix

dos2unix file_name

NB: you may need to install dos2unix first with yum install dos2unix

another way to do it is using sed command to search and replace the dos line ending characters to unix format:

$sed -i -e 's/\r$//' your_script.sh

Try with this:

          $.ajax({
              type: 'POST',
              url: URL,
              defaultHeaders: {
                  'Content-Type': 'application/json',
                  "Access-Control-Allow-Origin": "*",
                  'Accept': 'application/json'
               },

              data: obj,
              dataType: 'json',
              success: function (response) {
            //    BindTableData();
                console.log("success ");
                alert(response);
              },
              error: function (xhr) {
                console.log("error ");
                console.log(xhr);
              }
          });

Alternative solution, where you can have the database in the folder you want inside the solution. That worked for me:

.ConnectionString(@"Data Source=LocalDB)\MSSQLLocalDB;
                    AttachDbFilename="+AppDomain.CurrentDomain.BaseDirectory+"Folder1\\Folder2\\SampleDatabase.mdf" + ";
                    Integrated Security=True;")

I had the same problem but what worked for me was removing this from the Connection String:

persist security info=True

Just try to create the marker and set the draggable property to true. The code will be something as follows:

Marker = new google.maps.Marker({
    position: latlon,
    map: map,            
    draggable: true,
    title: "Drag me!"
});

I hope this helps!

This is pretty straightforward using the File class.

if(File.Exists(@"C:\test.txt"))
{
    File.Delete(@"C:\test.txt");
}

if you are using Eclipse watch your POM dependencies and your Eclipse buildpath dependency on junit

if you select use Junit4 eclipse create TestCase using org.junit package but your POM use by default Junit3 (junit.framework package) that is the cause, like this picture:

Just update your Junit dependency in your POM file to Junit4 or your Eclipse BuildPath to Junit3

For DEFAULT CURRENT_TIMESTAMP:

ALTER TABLE tablename
 CHANGE COLUMN columnname1 columname1 DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP,
 CHANGE COLUMN columnname2 columname2 DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP;

Please note double columnname declaration

Removing DEFAULT CURRENT_TIMESTAMP:

ALTER TABLE tablename
 ALTER COLUMN columnname1 DROP DEFAULT,
 ALTER COLUMN columnname2 DROPT DEFAULT;

Note that re.match(pattern, string, flags=0) only returns matches at the beginning of the string. If you want to locate a match anywhere in the string, use re.search(pattern, string, flags=0) instead (https://docs.python.org/3/library/re.html). This will scan the string and return the first match object. Then you can extract the matching string with match_object.group(0) as the folks suggested.

You might find this link helpful:

http://tldp.org/LDP/abs/html/string-manipulation.html

In general,

To replace the first match of $substring with $replacement:

${string/substring/replacement}

To replace all matches of $substring with $replacement:

${string//substring/replacement}

EDIT: Note that this applies to a variable named $string.

Found this as I was searching for which way is fastest to pull the second element of a 2-tuple list. Not what I wanted but ran same test as shown with a 3rd method plus test the zip method

setup = 'elements = [(1,1) for _ in range(100000)];from operator import itemgetter'
method1 = '[x[1] for x in elements]'
method2 = 'map(itemgetter(1), elements)'
method3 = 'dict(elements).values()'
method4 = 'zip(*elements)[1]'

import timeit
t = timeit.Timer(method1, setup)
print('Method 1: ' + str(t.timeit(100)))
t = timeit.Timer(method2, setup)
print('Method 2: ' + str(t.timeit(100)))
t = timeit.Timer(method3, setup)
print('Method 3: ' + str(t.timeit(100)))
t = timeit.Timer(method4, setup)
print('Method 4: ' + str(t.timeit(100)))

Method 1: 0.618785858154
Method 2: 0.711684942245
Method 3: 0.298138141632
Method 4: 1.32586884499

So over twice as fast if you have a 2 tuple pair to just convert to a dict and take the values.

Working one liner if you want a single result from the collection:

$ipAddy = [System.Net.Dns]::GetHostAddresses("yahoo.com")[0].IPAddressToString;

I recommend using subprocess if writing a beautiful and readable code is your cup of tea:

import subprocess
subprocess.Popen("rm -r my_dir", shell=True)

And if you are not a software engineer, then maybe consider using Jupyter; you can simply type bash commands:

!rm -r my_dir

Traditionally, you use shutil:

import shutil

You are getting undefined because you probably have the components outside React Router.

Remember that you need to make sure that the component from which you are calling this.props.location is inside a <Route /> component such as this:

<Route path="/dashboard" component={Dashboard} />

Then inside the Dashboard component, you have access to this.props.location...

Try simple code, to convert DataTable to excel file as csv:

var lines = new List<string>();

string[] columnNames = dataTable.Columns
    .Cast<DataColumn>()
    .Select(column => column.ColumnName)
    .ToArray();

var header = string.Join(",", columnNames.Select(name => $"\"{name}\""));
lines.Add(header);

var valueLines = dataTable.AsEnumerable()
    .Select(row => string.Join(",", row.ItemArray.Select(val => $"\"{val}\"")));

lines.AddRange(valueLines);

File.WriteAllLines("excel.csv", lines);

This will write a new file excel.csv into the current working directory which is generally either where the .exe is or where you launch it from.

Change <?php echo $proxy ?> to ' . $proxy . '.

You use <?php when you're outputting HTML by leaving PHP mode with ?>. When you using echo, you have to use concatenation, or wrap your string in double quotes and use interpolation.

Be careful when using Convert.ToInt32() on a char! It will return the UTF-16 code of the character!

If you access the string only in a certain position using the [i] indexing operator, it will return a char and not a string!

String input = "123678";
                    ^
                    |
int indexOfSeven =  4;

int x = Convert.ToInt32(input[indexOfSeven]);             // Returns 55

int x = Convert.ToInt32(input[indexOfSeven].toString());  // Returns 7

I do not unit test private methods. A private method is an implementation detail that should be hidden to the users of the class. Testing private methods breaks encapsulation.

If I find that the private method is huge or complex or important enough to require its own tests, I just put it in another class and make it public there (Method Object). Then I can easily test the previously-private-but-now-public method that now lives on its own class.

Two entries in an array can't share a key, you'll need to change the key for the duplicate

Windows INI API support for:

• Line comments: yes, using semi-colon ;
• Trailing comments: No

The authoritative source is the Windows API function that reads values out of INI files

GetPrivateProfileString

Retrieves a string from the specified section in an initialization file.

The reason "full line comments" work is because the requested value does not exist. For example, when parsing the following ini file contents:

[Application]
UseLiveData=1
;coke=zero
pepsi=diet   ;gag
#stackoverflow=splotchy

Reading the values:

• UseLiveData: 1
• coke: not present
• ;coke: not present
• pepsi: diet ;gag
• stackoverflow: not present
• #stackoverflow: splotchy

Update: I used to think that the number sign (#) was a pseudo line-comment character. The reason using leading # works to hide stackoverflow is because the name stackoverflow no longer exists. And it turns out that semi-colon (;) is a line-comment.

But there is no support for trailing comments.

Define a constructor in the abstract class which sets the field so that the concrete implementations are per the specification required to call/override the constructor.

E.g.

public abstract class AbstractTable {
    protected String name;

    public AbstractTable(String name) {
        this.name = name;
    }
}

When you extend AbstractTable, the class won't compile until you add a constructor which calls super("somename").

public class ConcreteTable extends AbstractTable {
    private static final String NAME = "concreteTable";

    public ConcreteTable() {
        super(NAME);
    }
}

This way the implementors are required to set name. This way you can also do (null)checks in the constructor of the abstract class to make it more robust. E.g:

public AbstractTable(String name) {
    if (name == null) throw new NullPointerException("Name may not be null");
    this.name = name;
}

The simplest solution is Go to Build Path > Configure Build Path > Java Compiler and then select the 'Compiler compliance level:' to the latest one from 1.4 (probably you have this).

The /EXCLUDE: argument expects a file containing a list of excluded files.

So create a file called excludedfileslist.txt containing:

.cs\

Then a command like this:

xcopy /r /d /i /s /y /exclude:excludedfileslist.txt C:\dev\apan C:\web\apan

Alternatively you could use Robocopy, but would require installing / copying a robocopy.exe to the machines.

Update

An anonymous comment edit which simply stated "This Solution exclude also css file!"

This is true creating a excludedfileslist.txt file contain just:

.cs

(note no backslash on the end)

Will also exclude all of the following:

• file1.cs
• file2.css
• dir1.cs\file3.txt
• dir2\anyfile.cs.something.txt

Sometimes people don't read or understand the XCOPY command's help, here is an item I would like to highlight:

Using /exclude

• List each string in a separate line in each file. If any of the listed strings match any part of the absolute path of the file to be copied, that file is then excluded from the copying process. For example, if you specify the string "\Obj\", you exclude all files underneath the Obj directory. If you specify the string ".obj", you exclude all files with the .obj extension.

As the example states it excludes "all files with the .obj extension" but it doesn't state that it also excludes files or directories named file1.obj.tmp or dir.obj.output\example2.txt.

There is a way around .css files being excluded also, change the excludedfileslist.txt file to contain just:

.cs\

(note the backslash on the end).

Here is a complete test sequence for your reference:

I've solved my problems, so I post here the correct code in case someone needs similar stuff.

Open Port

int USB = open( "/dev/ttyUSB0", O_RDWR| O_NOCTTY );

Set parameters

struct termios tty;
struct termios tty_old;
memset (&tty, 0, sizeof tty);

/* Error Handling */
if ( tcgetattr ( USB, &tty ) != 0 ) {
   std::cout << "Error " << errno << " from tcgetattr: " << strerror(errno) << std::endl;
}

/* Save old tty parameters */
tty_old = tty;

/* Set Baud Rate */
cfsetospeed (&tty, (speed_t)B9600);
cfsetispeed (&tty, (speed_t)B9600);

/* Setting other Port Stuff */
tty.c_cflag     &=  ~PARENB;            // Make 8n1
tty.c_cflag     &=  ~CSTOPB;
tty.c_cflag     &=  ~CSIZE;
tty.c_cflag     |=  CS8;

tty.c_cflag     &=  ~CRTSCTS;           // no flow control
tty.c_cc[VMIN]   =  1;                  // read doesn't block
tty.c_cc[VTIME]  =  5;                  // 0.5 seconds read timeout
tty.c_cflag     |=  CREAD | CLOCAL;     // turn on READ & ignore ctrl lines

/* Make raw */
cfmakeraw(&tty);

/* Flush Port, then applies attributes */
tcflush( USB, TCIFLUSH );
if ( tcsetattr ( USB, TCSANOW, &tty ) != 0) {
   std::cout << "Error " << errno << " from tcsetattr" << std::endl;
}

Write

unsigned char cmd[] = "INIT \r";
int n_written = 0,
    spot = 0;

do {
    n_written = write( USB, &cmd[spot], 1 );
    spot += n_written;
} while (cmd[spot-1] != '\r' && n_written > 0);

It was definitely not necessary to write byte per byte, also int n_written = write( USB, cmd, sizeof(cmd) -1) worked fine.

At last, read:

int n = 0,
    spot = 0;
char buf = '\0';

/* Whole response*/
char response[1024];
memset(response, '\0', sizeof response);

do {
    n = read( USB, &buf, 1 );
    sprintf( &response[spot], "%c", buf );
    spot += n;
} while( buf != '\r' && n > 0);

if (n < 0) {
    std::cout << "Error reading: " << strerror(errno) << std::endl;
}
else if (n == 0) {
    std::cout << "Read nothing!" << std::endl;
}
else {
    std::cout << "Response: " << response << std::endl;
}

This one worked for me. Thank you all!

Here's some code that might do the trick for you (taken from Ryan Farley's blog)

public static Control GetPostBackControl(Page page)
{
    Control control = null;

    string ctrlname = page.Request.Params.Get("__EVENTTARGET");
    if (ctrlname != null && ctrlname != string.Empty)
    {
        control = page.FindControl(ctrlname);
    }
    else
    {
        foreach (string ctl in page.Request.Form)
        {
            Control c = page.FindControl(ctl);
            if (c is System.Web.UI.WebControls.Button)
            {
                control = c;
                break;
            }
        }
    }
    return control;
}

char buffer [50];

unsigned long a = 5;

int n=sprintf (buffer, "%lu", a);

I could install app on Nexus, but couldn't on Samsung. Nothing helped me except the change of the USB cable.

Well, I'm not 100% sure, but I don't think jQuery extends/parses those functions and attributes (.paused, .pause(), .play()).

try to access those over the DOM element, like:

$('.player_audio').click(function() {
  if (this.paused == false) {
      this.pause();
      alert('music paused');
  } else {
      this.play();
      alert('music playing');
  }
});

For radio buttons use the following script:

var myRadio = $('input[name=meme_wall_share]');
var checkedValue = myRadio.filter(':checked').val();

Maybe this is unrelated but a similar error appears when you upgrade postgres to a major version using brew; using brew info postgresql found out this that helped:

To migrate existing data from a previous major version of PostgreSQL run:
brew postgresql-upgrade-database

Here's a version that works recursively (using *) on an arbitrary number of objects:

echo '{"A": {"a": 1}}' '{"A": {"b": 2}}' '{"B": 3}' |\
  jq --slurp 'reduce .[] as $item ({}; . * $item)'

{
  "A": {
    "a": 1,
    "b": 2
  },
  "B": 3
}

You can use from bellow code for date and time :

DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
       //get current date time with Calendar()
       Calendar cal = Calendar.getInstance();
       System.out.println("Current Date Time : " + dateFormat.format(cal.getTime()));

       cal.add(Calendar.DATE, 1);
       System.out.println("Add one day to current date : " + dateFormat.format(cal.getTime()));

       cal = Calendar.getInstance();
       cal.add(Calendar.MONTH, 1);
       System.out.println("Add one month to current date : " + dateFormat.format(cal.getTime()));

       cal = Calendar.getInstance();
       cal.add(Calendar.YEAR, 1);
       System.out.println("Add one year to current date : " + dateFormat.format(cal.getTime()));

       cal = Calendar.getInstance();
       cal.add(Calendar.HOUR, 1);
       System.out.println("Add one hour to current date : " + dateFormat.format(cal.getTime()));

       cal = Calendar.getInstance();
       cal.add(Calendar.MINUTE, 1);
       System.out.println("Add one minute to current date : " + dateFormat.format(cal.getTime()));

       cal = Calendar.getInstance();
       cal.add(Calendar.SECOND, 1);
       System.out.println("Add one second to current date : " + dateFormat.format(cal.getTime()));

       cal = Calendar.getInstance();
       cal.add(Calendar.DATE, -1);
       System.out.println("Subtract one day from current date : " + dateFormat.format(cal.getTime()));

       cal = Calendar.getInstance();
       cal.add(Calendar.MONTH, -1);
       System.out.println("Subtract one month from current date : " + dateFormat.format(cal.getTime()));

       cal = Calendar.getInstance();
       cal.add(Calendar.YEAR, -1);
       System.out.println("Subtract one year from current date : " + dateFormat.format(cal.getTime()));

       cal = Calendar.getInstance();
       cal.add(Calendar.HOUR, -1);
       System.out.println("Subtract one hour from current date : " + dateFormat.format(cal.getTime()));

       cal = Calendar.getInstance();
       cal.add(Calendar.MINUTE, -1);
       System.out.println("Subtract one minute from current date : " + dateFormat.format(cal.getTime()));

       cal = Calendar.getInstance();
       cal.add(Calendar.SECOND, -1);
       System.out.println("Subtract one second from current date : " + dateFormat.format(cal.getTime()));

Output :

Current Date Time : 2008/12/28 10:24:53
Add one day to current date : 2008/12/29 10:24:53
Add one month to current date : 2009/01/28 10:24:53

If you need just time :

DateFormat dateFormat = new SimpleDateFormat("HH:mm:ss");

As you already state in your question, the main difference between union and struct is that union members overlay the memory of each other so that the sizeof of a union is the one , while struct members are laid out one after each other (with optional padding in between). Also an union is large enough to contain all its members, and have an alignment that fits all its members. So let's say int can only be stored at 2 byte addresses and is 2 bytes wide, and long can only be stored at 4 byte addresses and is 4 bytes long. The following union

union test {
    int a;
    long b;
}; 

could have a sizeof of 4, and an alignment requirement of 4. Both an union and a struct can have padding at the end, but not at their beginning. Writing to a struct changes only the value of the member written to. Writing to a member of an union will render the value of all other members invalid. You cannot access them if you haven't written to them before, otherwise the behavior is undefined. GCC provides as an extension that you can actually read from members of an union, even though you haven't written to them most recently. For an Operation System, it doesn't have to matter whether a user program writes to an union or to a structure. This actually is only an issue of the compiler.

Another important property of union and struct is, they allow that a pointer to them can point to types of any of its members. So the following is valid:

struct test {
    int a;
    double b;
} * some_test_pointer;

some_test_pointer can point to int* or double*. If you cast an address of type test to int*, it will point to its first member, a, actually. The same is true for an union too. Thus, because an union will always have the right alignment, you can use an union to make pointing to some type valid:

union a {
    int a;
    double b;
};

That union will actually be able to point to an int, and a double:

union a * v = (union a*)some_int_pointer;
*some_int_pointer = 5;
v->a = 10;
return *some_int_pointer;    

is actually valid, as stated by the C99 standard:

An object shall have its stored value accessed only by an lvalue expression that has one of the following types:

• a type compatible with the effective type of the object
• ...
• an aggregate or union type that includes one of the aforementioned types among its members

The compiler won't optimize out the v->a = 10; as it could affect the value of *some_int_pointer (and the function will return 10 instead of 5).

How about:

df <- data.frame(matrix(ncol = 3, nrow = 0))
x <- c("name", "age", "gender")
colnames(df) <- x

To do all these operations in one-liner:

setNames(data.frame(matrix(ncol = 3, nrow = 0)), c("name", "age", "gender"))

#[1] name   age    gender
#<0 rows> (or 0-length row.names)

Or

data.frame(matrix(ncol=3,nrow=0, dimnames=list(NULL, c("name", "age", "gender"))))

I don't know if this will help with your current predicament as this is a recent feature, but you can specify the visibility of symbols in a global manner. Passing -fvisibility=hidden -fvisibility-inlines-hidden at compilation can help the linker to later get rid of unneeded symbols. If you're producing an executable (as opposed to a shared library) there's nothing more to do.

More information (and a fine-grained approach for e.g. libraries) is available on the GCC wiki.

pdfrw will let you read in pages from an existing PDF and draw them to a reportlab canvas (similar to drawing an image). There are examples for this in the pdfrw examples/rl1 subdirectory on github. Disclaimer: I am the pdfrw author.

System.Net.HttpWebRequest adds the header 'HTTP header "Expect: 100-Continue"' to every request unless you explicitly ask it not to by setting this static property to false:

System.Net.ServicePointManager.Expect100Continue = false;

Some servers choke on that header and send back the 417 error you're seeing.

Give that a shot.

As soon as signed and unsigned ints are mixed in an expression things start to get messy and you probably will lose information. Restricting Java to signed ints only really clears things up. I’m glad I don’t have to worry about the whole signed/unsigned business, though I sometimes do miss the 8th bit in a byte.

A string holds one value, but a string[] holds many strings, as it's an array of string.

If an immutable map fits your needs then there is a library by google called guava (see also guava questions)

Guava provides an ImmutableMap with reliable user-specified iteration order. This ImmutableMap has O(1) performance for containsKey, get. Obviously put and remove are not supported.

ImmutableMap objects are constructed by using either the elegant static convenience methods of() and copyOf() or a Builder object.

Remove the width:100%; declarations.

Block elements should take up the whole available width by default.

You want set_ticks_position rather than set_label_position:

ax.xaxis.set_ticks_position('top') # the rest is the same

This gives me:

Marc Gravell's answer is very complete, but I thought I'd add something about this from the user's point of view, as well...

The main difference, from a user's perspective, is that, when you use IQueryable<T> (with a provider that supports things correctly), you can save a lot of resources.

For example, if you're working against a remote database, with many ORM systems, you have the option of fetching data from a table in two ways, one which returns IEnumerable<T>, and one which returns an IQueryable<T>. Say, for example, you have a Products table, and you want to get all of the products whose cost is >$25.

If you do:

 IEnumerable<Product> products = myORM.GetProducts();
 var productsOver25 = products.Where(p => p.Cost >= 25.00);

What happens here, is the database loads all of the products, and passes them across the wire to your program. Your program then filters the data. In essence, the database does a SELECT * FROM Products, and returns EVERY product to you.

With the right IQueryable<T> provider, on the other hand, you can do:

 IQueryable<Product> products = myORM.GetQueryableProducts();
 var productsOver25 = products.Where(p => p.Cost >= 25.00);

The code looks the same, but the difference here is that the SQL executed will be SELECT * FROM Products WHERE Cost >= 25.

From your POV as a developer, this looks the same. However, from a performance standpoint, you may only return 2 records across the network instead of 20,000....
