You are just creating your array incorrectly. You could use http_build_query:

$fields = array(
            'username' => "annonymous",
            'api_key' => urlencode("1234"),
            'images' => array(
                 urlencode(base64_encode('image1')),
                 urlencode(base64_encode('image2'))
            )
        );
$fields_string = http_build_query($fields);

So, the entire code that you could use would be:

<?php
//extract data from the post
extract($_POST);

//set POST variables
$url = 'http://api.example.com/api';
$fields = array(
            'username' => "annonymous",
            'api_key' => urlencode("1234"),
            'images' => array(
                 urlencode(base64_encode('image1')),
                 urlencode(base64_encode('image2'))
            )
        );

//url-ify the data for the POST
$fields_string = http_build_query($fields);

//open connection
$ch = curl_init();

//set the url, number of POST vars, POST data
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_POST, 1);
curl_setopt($ch,CURLOPT_POSTFIELDS, $fields_string);

//execute post
$result = curl_exec($ch);
echo $result;

//close connection
curl_close($ch);
?>

Any easy way to cover ALL file inputs is to just style your input[type=button] and drop this in globally to turn file inputs into buttons:

$(document).ready(function() {
    $("input[type=file]").each(function () {
        var thisInput$ = $(this);
        var newElement = $("<input type='button' value='Choose File' />");
        newElement.click(function() {
            thisInput$.click();
        });
        thisInput$.after(newElement);
        thisInput$.hide();
    });
});

Here's some sample button CSS that I got from http://cssdeck.com/labs/beautiful-flat-buttons:

input[type=button] {
  position: relative;
  vertical-align: top;
  width: 100%;
  height: 60px;
  padding: 0;
  font-size: 22px;
  color:white;
  text-align: center;
  text-shadow: 0 1px 2px rgba(0, 0, 0, 0.25);
  background: #454545;
  border: 0;
  border-bottom: 2px solid #2f2e2e;
  cursor: pointer;
  -webkit-box-shadow: inset 0 -2px #2f2e2e;
  box-shadow: inset 0 -2px #2f2e2e;
}
input[type=button]:active {
  top: 1px;
  outline: none;
  -webkit-box-shadow: none;
  box-shadow: none;
}

Setting the cursor for 'body' will change the cursor for the background of the page but not for controls on it. For example, buttons will still have the regular cursor when hovering over them. The following is what I am using:

To set the 'wait' cursor, create a style element and insert in the head:

var css = "* { cursor: wait; !important}";
var style = document.createElement("style");
style.type = "text/css";
style.id = "mywaitcursorstyle";
style.appendChild(document.createTextNode(css));
document.head.appendChild(style);

Then to restore the cursor, delete the style element:

var style = document.getElementById("mywaitcursorstyle");
if (style) {
  style.parentNode.removeChild(style);
}

Well, I believe that I've solved the password configuration 'issue' - WampServer 2.2 - Windows 7.

The three steps that I did:

1. In the MySQL console set a new password. To make that: mysqladmin -u root password 'your_password'

2. In phpMyAdmin click in users and set the same password to the user root.

3. Finally, set your new password in the config.inc.php. Don't change anything else in this file.

This worked for me. Good luck!

Bugginess* in the new Drupal 8 capabilities here inspired us to write our own:

<a href="{{ view_node }}">{% if title|length > 32 %}{% set title_array = title|split(' ') %}{% set title_word_count = 0 %}{% for ta in title_array %}{% set word_count = ta|length %}{% if title_word_count < 32 %}{% set title_word_count = title_word_count + word_count %}{{ ta }} {% endif %}{% endfor %}...{% else %}{{ title }}{% endif %}</a>

This takes into consideration both words and characters (*the "word boundary" setting in D8 was displaying nothing).

IMHO, this looks better:

Chess *array = malloc(size * sizeof(Chess)); // array of pointers of size `size`

for ( int i =0; i < SOME_VALUE; ++i )
{
    array[i] = (Chess) malloc(sizeof(Chess));
}

Your Test2 class is not a Component, it has a Component which is a difference.

Either you do something like

frame.add(test.getPanel() );

after you introduced a getter for the panel in your class, or you make sure your Test2 class becomes a Component (e.g. by extending a JPanel)

Adding to other answers, the following helped me finish the installation mysql-python:

virtualenv, mysql-python, pip: anyone know how?

On Ubuntu...

apt-get install libmysqlclient-dev
apt-get install python-dev
pip install mysql-python

Don't forget to add 'sudo' to the beginning of commands if you don't have the proper permissions.

From the Xcode menu on top, click preferences, select the locations tab, look at the build location option.

You have 2 options:

1. Place build products in derived data location (recommended)
2. Place build products in locations specified by targets

Update: On xcode 4.6.2 you need to click the advanced button on the right side below the derived data text field. Build Location select legacy.

No use of any pre defined function as well as efficient: --- >>

     d = in.nextInt();

        for ( i=0;i< size;i++)

Avoid Eclipse for C/C++ development for now on Mac OS X v10.6 (Snow Leopard). There are serious problems which make debugging problematic or nearly impossible on it currently due to GDB incompatibility problems and the like. See: Trouble debugging C++ using Eclipse Galileo on Mac.

I post my solution in Kotlin, but it can work with java objects as well. I create a function extension so any object can use this function.

fun Any.iterateOverComponents() {

val fields = this.javaClass.declaredFields

fields.forEachIndexed { i, field ->

    fields[i].isAccessible = true
    // get value of the fields
    val value = fields[i].get(this)

    // print result
    Log.w("Msg", "Value of Field "
            + fields[i].name
            + " is " + value)
}}

Take a look at this webpage: https://www.geeksforgeeks.org/field-get-method-in-java-with-examples/

As well as \singlespacing mentioned previously to reduce the height of the table, a useful way to reduce the width of the table is to add \tabcolsep=0.11cm before the \begin{tabular} command and take out all the vertical lines between columns. It's amazing how much space is used up between the columns of text. You could reduce the font size to something smaller than \small but I normally wouldn't use anything smaller than \footnotesize.

I am using Ubuntu 16.04. For me it was the incorrect interpretor, which was by default using the virtual interpretor from project.

So, make sure you select the correct one, as the pip install will install the package to system python interpretor.

Just go to follow link domain.com/wp-admin/about.php

In addition to that, passing true to $.noConflict(true); will also restore previous (if any) global variable jQuery, so that plugins can be initialized with correct jQuery version when multiple versions are being used.

Not programming related, but I'll answer anyway. It's in /etc/hosts.

You can change it with a simple text editor such as nano.

(Obviously you would need a jailbroken iphone for this)

You can assign one color to every functionality to make it more useful.

#define Color_Red "\33[0:31m\\]" // Color Start
#define Color_end "\33[0m\\]" // To flush out prev settings
#define LOG_RED(X) printf("%s %s %s",Color_Red,X,Color_end)

foo()
{
LOG_RED("This is in Red Color");
}

Like wise you can select different color codes and make this more generic.

DATA = { u'spam': u'eggs', u'foo': frozenset([u'Gah!']), u'bar': { u'baz': 97 },
         u'list': [u'list', (True, u'Maybe'), set([u'and', u'a', u'set', 1])]}

def convert(data):
    if isinstance(data, basestring):
        return str(data)
    elif isinstance(data, collections.Mapping):
        return dict(map(convert, data.iteritems()))
    elif isinstance(data, collections.Iterable):
        return type(data)(map(convert, data))
    else:
        return data

print DATA
print convert(DATA)
# Prints:
# {u'list': [u'list', (True, u'Maybe'), set([u'and', u'a', u'set', 1])], u'foo': frozenset([u'Gah!']), u'bar': {u'baz': 97}, u'spam': u'eggs'}
# {'bar': {'baz': 97}, 'foo': frozenset(['Gah!']), 'list': ['list', (True, 'Maybe'), set(['and', 'a', 'set', 1])], 'spam': 'eggs'}

Assumptions:

• You've imported the collections module and can make use of the abstract base classes it provides
• You're happy to convert using the default encoding (use data.encode('utf-8') rather than str(data) if you need an explicit encoding).

If you need to support other container types, hopefully it's obvious how to follow the pattern and add cases for them.

div.abc.xyz {
    /* rules go here */
}

... or simply:

.abc.xyz {
    /* rules go here */
}

Here's what I did:

var timestamp = moment.unix({{ time }});
var utcOffset = moment().utcOffset();
var local_time = timestamp.add(utcOffset, "minutes");
var dateString = local_time.fromNow();

Where {{ time }} is the utc timestamp.

It depends on the jQuery selector that you use. Since id should be unique within the DOM, the first one would be simple:

$('#Comanda').hide();

The second one might require something more, depending on the other elements and how to uniquely identify it. If the name of that particular input is unique, then this would work:

$('input[name="Vizualizeaza"]').hide();

The prompt command will echo text to the output:

prompt A useful comment.
select(*) from TableA;

Will be displayed as:

SQL> A useful comment.
SQL> 
  COUNT(*)
----------
     0

Yes, you should always call base class __init__ explicitly as a good coding practice. Forgetting to do this can cause subtle issues or run time errors. This is true even if __init__ doesn't take any parameters. This is unlike other languages where compiler would implicitly call base class constructor for you. Python doesn't do that!

The main reason for always calling base class _init__ is that base class may typically create member variable and initialize them to defaults. So if you don't call base class init, none of that code would be executed and you would end up with base class that has no member variables.

Example:

class Base:
  def __init__(self):
    print('base init')

class Derived1(Base):
  def __init__(self):
    print('derived1 init')

class Derived2(Base):
  def __init__(self):
    super(Derived2, self).__init__()
    print('derived2 init')

print('Creating Derived1...')
d1 = Derived1()
print('Creating Derived2...')
d2 = Derived2()

This prints..

Creating Derived1...
derived1 init
Creating Derived2...
base init
derived2 init

Run this code.

value_counts omits NaN by default so you're most likely dealing with "".

So you can just filter them out like

filter = df["Tenant"] != ""
dfNew = df[filter]

The use-case for CORS is simple. Imagine the site alice.com has some data that the site bob.com wants to access. This type of request traditionally wouldn’t be allowed under the browser’s same origin policy. However, by supporting CORS requests, alice.com can add a few special response headers that allows bob.com to access the data. In order to understand it well, please visit this nice tutorial.. How to solve the issue of CORS

In my case it was a connection problem. I was connected to an internal wifi network, in which I had limited access to ressources. That was letting git do the fetch but at a certain time it crashed. This means it can be a network-connection problem. Check if everything is running properly: Antivirus, Firewall, etc.

The answer of elin3t is therefore important because ssh improves the performance of the downloading so that network problems can be avoided

You should set default values in migrations:

$table->tinyInteger('role')->default(1);

In my case, I have installed angular-cli locally using npm install --save-dev angular-cli. So, when I use command npm install -g @angular/cli, it generates error saying that "Your global Angular CLI version (1.7.3) is greater than your local version (1.4.9)". Please note that angular-cli, @angular/cli and @angular/cli@latest are two different cli's. What solves this is uninstall all cli and then install latest angular cli using npm install -g @angular/cli@latest

You can also use DEV_RANDOM, where 128 = 1/2 the generated token length. Code below generates 256 token.

$token = bin2hex(mcrypt_create_iv(128, MCRYPT_DEV_RANDOM));

I use this solution to delete empty lines and join everything together as one line:

match_p = re.sub(r'\s{2}', '', my_txt) # my_txt is text above

#pragma warning( push )
#pragma warning( disable : 4101)
// Your function
#pragma warning( pop ) 

$("a").click(function(){
                alert('disabled');
                return false;

}); 

this is my solution:

var matrixRegex = /(?:matrix\(|\s*,\s*)([-+]?[0-9]*\.?[0-9]+(?:[e][-+]?[0-9]+)?)/gi;

var getMatches = function(string, regex) {
    regex || (regex = matrixRegex);
    var matches = [];
    var match;
    while (match = regex.exec(string)) {
        matches.push(match[1]);
    }
    return matches;
};

$.cssHooks['rotation'] = {
    get: function(elem) {
        var $elem = $(elem);
        var matrix = getMatches($elem.css('transform'));
        if (matrix.length != 6) {
            return 0;
        }
        return Math.atan2(parseFloat(matrix[1]), parseFloat(matrix[0])) * (180/Math.PI);
    }, 
    set: function(elem, val){
        var $elem = $(elem);
        var deg = parseFloat(val);
        if (!isNaN(deg)) {
            $elem.css({ transform: 'rotate(' + deg + 'deg)' });
        }
    }
};
$.cssNumber.rotation = true;
$.fx.step.rotation = function(fx) {
    $.cssHooks.rotation.set(fx.elem, fx.now + fx.unit);
};

then you can use it in the default animate fkt:

//rotate to 90 deg cw
$('selector').animate({ rotation: 90 });

//rotate to -90 deg ccw
$('selector').animate({ rotation: -90 });

//rotate 90 deg cw from current rotation
$('selector').animate({ rotation: '+=90' });

//rotate 90 deg ccw from current rotation
$('selector').animate({ rotation: '-=90' });

I know this is an old question, but I wanted to make sure a couple of other options are noted.

Since you can't store a TimeSpan greater than 24 hours in a time sql datatype field; a couple of other options might be.

1. Use a varchar(xx) to store the ToString of the TimeSpan. The benefit of this is the precision doesn't have to be baked into the datatype or the calculation, (seconds vs milliseconds vs days vs fortnights) All you need to to is use TimeSpan.Parse/TryParse. This is what I would do.

2. Use a second date, datetime or datetimeoffset, that stores the result of first date + timespan. Reading from the db is a matter of TimeSpan x = SecondDate - FirstDate. Using this option will protect you for other non .NET data access libraries access the same data but not understanding TimeSpans; in case you have such an environment.

I've had a similar requirement: I needed to inject a Spring-managed repository bean into my Person entity class ("entity" as in "something with an identity", for example an JPA entity). A Person instance has friends, and for this Person instance to return its friends, it shall delegate to its repository and query for friends there.

@Entity
public class Person {
    private static PersonRepository personRepository;

    @Id
    @GeneratedValue
    private long id;

    public static void setPersonRepository(PersonRepository personRepository){
        this.personRepository = personRepository;
    }

    public Set<Person> getFriends(){
        return personRepository.getFriends(id);
    }

    ...
}

.

@Repository
public class PersonRepository {

    public Person get Person(long id) {
        // do database-related stuff
    }

    public Set<Person> getFriends(long id) {
        // do database-related stuff
    }

    ...
}

So how did I inject that PersonRepository singleton into the static field of the Person class?

I created a @Configuration, which gets picked up at Spring ApplicationContext construction time. This @Configuration gets injected with all those beans that I need to inject as static fields into other classes. Then with a @PostConstruct annotation, I catch a hook to do all static field injection logic.

@Configuration
public class StaticFieldInjectionConfiguration {

    @Inject
    private PersonRepository personRepository;

    @PostConstruct
    private void init() {
        Person.setPersonRepository(personRepository);
    }
}

Not sure what you are really after but if you want to print exactly what you have you can do:

Option 1

print(df['Item'].to_csv(index=False))

Sweet
Candy
Chocolate

Option 2

for v in df['Item']:
    print(v)

Sweet
Candy
Chocolate

Try this way ->

Firstly create a class TimeTask that run your task, it looks like:

public class CustomTask extends TimerTask  {

   public CustomTask(){

     //Constructor

   }

   public void run() {
       try {

         // Your task process

       } catch (Exception ex) {
           System.out.println("error running thread " + ex.getMessage());
       }
    }
}

then in main class you instantiate the task and run it periodically started by a specified date:

 public void runTask() {

        Calendar calendar = Calendar.getInstance();
        calendar.set(
           Calendar.DAY_OF_WEEK,
           Calendar.MONDAY
        );
        calendar.set(Calendar.HOUR_OF_DAY, 15);
        calendar.set(Calendar.MINUTE, 40);
        calendar.set(Calendar.SECOND, 0);
        calendar.set(Calendar.MILLISECOND, 0);



        Timer time = new Timer(); // Instantiate Timer Object

        // Start running the task on Monday at 15:40:00, period is set to 8 hours
        // if you want to run the task immediately, set the 2nd parameter to 0
        time.schedule(new CustomTask(), calendar.getTime(), TimeUnit.HOURS.toMillis(8));
}

If you need to open Emacs without X:

emacs -nw

Just use = IF(A1="Bla*","YES","NO"). When you insert the asterisk, it acts as a wild card for any amount of characters after the specified text.

I ended up here and my issue was that I was querying for

{$not: {email: /@domain.com/}}

instead of

{email: {$not: /@domain.com/}}

So, @Vivek has got the solution to the problem through a dialogue in the Comments rather than through an actual answer.

"The file is being created by user oracle just noticed this in our development database. i'm getting this error because, the directory where i try to create the file doesn't have write access for others and user oracle comes under others category. "

Who says SO is a Q&A site not a forum? Er, me, amongst others. Anyway, in the absence of an accepted answer to this question I proffer a link to an answer of mine on the topic of UTL_FILE.FOPEN(). Find it here.

P.S. I'm marking this answer Community Wiki, because it's not a proper answer to this question, just a redirect to somewhere else.

You can also use,

parent.jQuery("#testdiv").attr("style", content from form);

The default constructor initializes the string to the empty string. This is the more economic way of saying the same thing.

However, the comparison to NULL stinks. That is an older syntax still in common use that means something else; a null pointer. It means that there is no string around.

If you want to check whether a string (that does exist) is empty, use the empty method instead:

if (myStr.empty()) ...

Headings are normally bold-faced; that has been turned off for this demonstration of size correspondence. MSIE and Opera interpret these sizes the same, but note that Gecko browsers and Chrome interpret Heading 6 as 11 pixels instead of 10 pixels/font size 1, and Heading 3 as 19 pixels instead of 18 pixels/font size 4 (though it's difficult to tell the difference even in a direct comparison and impossible in use). It seems Gecko also limits text to no smaller than 10 pixels.

In addition to anyListOf above, you can always specify generics explicitly using this syntax:

when(mock.process(Matchers.<List<Bar>>any(List.class)));

Java 8 newly allows type inference based on parameters, so if you're using Java 8, this may work as well:

when(mock.process(Matchers.any()));

Remember that neither any() nor anyList() will apply any checks, including type or null checks. In Mockito 2.x, any(Foo.class) was changed to mean "any instanceof Foo", but any() still means "any value including null".

NOTE: The above has switched to ArgumentMatchers in newer versions of Mockito, to avoid a name collision with org.hamcrest.Matchers. Older versions of Mockito will need to keep using org.mockito.Matchers as above.

sh: http://man.cx/sh
bash: http://man.cx/bash

TL;DR: bash is a superset of sh with a more elegant syntax and more functionality. It is safe to use a bash shebang line in almost all cases as it's quite ubiquitous on modern platforms.

NB: in some environments, sh is bash. Check sh --version.

Additionally, you can use Google CityHash:

#include <stddef.h>
#include <stdio.h>
#include <string.h>

#include <byteswap.h>

#include "city.h"

I have run into this before and trying a number of things has fixed it for me:

• Delete a bin folder if it exists
• Delete the hidden .vs folder
• Make sure the 4.6.1 targeting pack is installed
• Last Ditch Effort: Add a reference to System.Runtime (right click project -> add -> reference -> tick the box next to System.Runtime), although I think I've always figured out one of the above has solved it instead of doing this.

Also, if this is a .net core app running on the full framework, I've found you have to include a global.json file at the root of your project and point it to the SDK you want to use for that project:

{
  "sdk": {
    "version": "1.0.0-preview2-003121"
  }
}

The easisest thing to do is to wrap your code in a transaction, and then execute each batch of T-SQL code line by line.

For example,

Begin Transaction

         -Do some T-SQL queries here.

Rollback transaction -- OR commit transaction

If you want to incorporate error handling you can do so by using a TRY...CATCH BLOCK. Should an error occur you can then rollback the tranasction within the catch block.

For example:

USE AdventureWorks;
GO
BEGIN TRANSACTION;

BEGIN TRY
    -- Generate a constraint violation error.
    DELETE FROM Production.Product
    WHERE ProductID = 980;
END TRY
BEGIN CATCH
    SELECT 
        ERROR_NUMBER() AS ErrorNumber
        ,ERROR_SEVERITY() AS ErrorSeverity
        ,ERROR_STATE() AS ErrorState
        ,ERROR_PROCEDURE() AS ErrorProcedure
        ,ERROR_LINE() AS ErrorLine
        ,ERROR_MESSAGE() AS ErrorMessage;

    IF @@TRANCOUNT > 0
        ROLLBACK TRANSACTION;
END CATCH;

IF @@TRANCOUNT > 0
    COMMIT TRANSACTION;
GO

Hope this helps but please let me know if you need more details.

In Bootstrap 4 it was renamed to .rounded-circle

Usage :

<div class="col-xs-7">
    <img src="img/gallery2.JPG" class="rounded-circle" alt="HelPic>
</div>

See migration docs from bootstrap.

You can add style to your text:

  style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0); 
    text-shadow: rgb(255, 255, 255) -2px -2px 0px, rgb(255, 255, 255) -2px 2px 0px, 
     rgb(255, 255, 255) 2px -2px 0px, rgb(255, 255, 255) 2px 2px 0px;"

White, in this example. Does not work in IE :)

I've been trying to do this in Jupyter Lab so thought it might be useful to post the answer here. You can find the shortcuts in settings and also add your own, where a full list of the possible shortcuts can be found here.

For example, I added my own shortcut to run all cells. In Jupyter Lab, under Settings > Advanced Settings, select Keyboard Shortcuts, then add the following code to 'User Overrides':

{
    "notebook:run-all-cells": {
      "command": "notebook:run-all-cells",
      "keys": [
        "Shift Backspace"
      ],
      "selector": ".jp-Notebook.jp-mod-editMode"
    }
}

Here, Shift + Backspace will run all cells in the notebook.

Try the below code to unprotect the workbook. It works for me just fine in excel 2010 but I am not sure if it will work in 2013.

I had this problem myself. Most of the information I could find online was related to people having this problem with an ASP.NET web application. I was creating a Win Forms stand alone app so most of the advice wasn't helpful for me.

Turns out that the problem was that my project was set to use the ".NET 4 Framework Client Profile" as the target framework and the System.Web.Extensions reference was not in the list for adding. I changed the target to ".NET 4 Framework" and then the reference was available by the normal methods.

Here is what worked for me step by step:

1. Right Click you project Select Properties
2. Change your Target Framework to ".NET Framework 4"
3. Do whatever you need to do to save the changes and close the preferences tab
4. Right click on the References item in your Solution Explorer
5. Choose Add Reference...
6. In the .NET tab, scroll down to System.Web.Extensions and add it.

The pointsize command scales the size of points, but does not affect the size of dots.

In other words, plot ... with points ps 2 will generate points of twice the normal size, but for plot ... with dots ps 2 the "ps 2" part is ignored.

You could use circular points (pt 7), which look just like dots.

Posts by John Peter and Dileep kurahe helped me to develop what I consider as being a simpler and cleaner solution, just in case anyone else is still looking. (I am not showing any database code because I actually used a $_SESSION variable.)

The above solutions invariably caused an error upon loading in Excel, about the extension not matching the formatting type. And some of these solutions create a spreadsheet with the data across the page in columns where it would be more traditional to have column headings and list the data down the rows. So here is my simple solution:

$filename = "webreport.csv";
header("Content-Type: application/xls");    
header("Content-Disposition: attachment; filename=$filename");  
header("Pragma: no-cache"); 
header("Expires: 0");
foreach($results as $x => $x_value){
    echo '"'.$x.'",' . '"'.$x_value.'"' . "\r\n";
}

1. Change to .csv (which Excel instantly updates to .xls and there is no error upon loading.)
2. Use the comma as delimiter.
3. Double quote the Key and Value to escape any commas in the data.
4. I also prepended column headers to $results so the spreadsheet looked even nicer.

Typically, you'd use a built-in layout control appropriate for your scenario (e.g. use a grid as a parent if you want scaling relative to the parent). If you want to do it with an arbitrary parent element, you can create a ValueConverter do it, but it probably won't be quite as clean as you'd like. However, if you absolutely need it, you could do something like this:

public class PercentageConverter : IValueConverter
{
    public object Convert(object value, 
        Type targetType, 
        object parameter, 
        System.Globalization.CultureInfo culture)
    {
        return System.Convert.ToDouble(value) * 
               System.Convert.ToDouble(parameter);
    }

    public object ConvertBack(object value, 
        Type targetType, 
        object parameter, 
        System.Globalization.CultureInfo culture)
    {
        throw new NotImplementedException();
    }
}

Which can be used like this, to get a child textbox 10% of the width of its parent canvas:

<Window x:Class="WpfApplication1.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="clr-namespace:WpfApplication1"
    Title="Window1" Height="300" Width="300">
    <Window.Resources>
        <local:PercentageConverter x:Key="PercentageConverter"/>
    </Window.Resources>
    <Canvas x:Name="canvas">
        <TextBlock Text="Hello"
                   Background="Red" 
                   Width="{Binding 
                       Converter={StaticResource PercentageConverter}, 
                       ElementName=canvas, 
                       Path=ActualWidth, 
                       ConverterParameter=0.1}"/>
    </Canvas>
</Window>

I'm not sure whether it is a new feature in later versions of matplotlib, but at least for 1.3.1, this is simply:

plt.title(figure_title, y=1.08)

This also works for plt.suptitle(), but not (yet) for plt.xlabel(), etc.

You don't have jdk1.7.0_17 in your PATH - check again. There is only JRE which may not contain 'javac' compiler.

Besides it is best to set JAVA_HOME variable, and then include it in PATH.

A difference between print and sys.stdout.write to point out in Python 3, is also the value which is returned when executed in the terminal. In Python 3, sys.stdout.write returns the length of the string whereas print returns just None.

So for example running following code interactively in the terminal would print out the string followed by its length, since the length is returned and output when run interactively:

>>> sys.stdout.write(" hi ")
 hi 4

Try this pattern:

public static PricesResponse getResponse(EventRequestRaw request) {

    // String urlParameters  = "param1=a&param2=b&param3=c";
    String urlParameters = Piping.serialize(request);

    HttpURLConnection conn = RestClient.getPOSTConnection(endPoint, urlParameters);

    PricesResponse response = null;

    try {
        // POST
        OutputStreamWriter writer = new OutputStreamWriter(conn.getOutputStream());
        writer.write(urlParameters);
        writer.flush();

        // RESPONSE
        BufferedReader reader = new BufferedReader(new InputStreamReader((conn.getInputStream()), StandardCharsets.UTF_8));
        String json = Buffering.getString(reader);
        response = (PricesResponse) Piping.deserialize(json, PricesResponse.class);

        writer.close();
        reader.close();

    } catch (Exception e) {
        e.printStackTrace();
    }

    conn.disconnect();

    System.out.println("PricesClient: " + response.toString());

    return response;
}

public static HttpURLConnection getPOSTConnection(String endPoint, String urlParameters) {

    return RestClient.getConnection(endPoint, "POST", urlParameters);

}


public static HttpURLConnection getConnection(String endPoint, String method, String urlParameters) {

    System.out.println("ENDPOINT " + endPoint + " METHOD " + method);
    HttpURLConnection conn = null;

    try {
        URL url = new URL(endPoint);
        conn = (HttpURLConnection) url.openConnection();
        conn.setRequestMethod(method);
        conn.setDoOutput(true);
        conn.setRequestProperty("Content-Type", "text/plain");

    } catch (IOException e) {
        e.printStackTrace();
    }

    return conn;
}

While not recommended, you can also disable SSL cert validation alltogether:

import javax.net.ssl.*;
import java.security.SecureRandom;
import java.security.cert.X509Certificate;

public class SSLTool {

  public static void disableCertificateValidation() {
    // Create a trust manager that does not validate certificate chains
    TrustManager[] trustAllCerts = new TrustManager[] { 
      new X509TrustManager() {
        public X509Certificate[] getAcceptedIssuers() { 
          return new X509Certificate[0]; 
        }
        public void checkClientTrusted(X509Certificate[] certs, String authType) {}
        public void checkServerTrusted(X509Certificate[] certs, String authType) {}
    }};

    // Ignore differences between given hostname and certificate hostname
    HostnameVerifier hv = new HostnameVerifier() {
      public boolean verify(String hostname, SSLSession session) { return true; }
    };

    // Install the all-trusting trust manager
    try {
      SSLContext sc = SSLContext.getInstance("SSL");
      sc.init(null, trustAllCerts, new SecureRandom());
      HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
      HttpsURLConnection.setDefaultHostnameVerifier(hv);
    } catch (Exception e) {}
  }
}

You can use:

skopeo inspect docker://<REMOTE_REGISTRY> --authfile <PULL_SECRET> | jq .RepoTags

The solution is just 3 lines:

@media only screen and (max-width: 479px) {
   .nav-tabs > li {
      width: 100%;
   }
}

..but you have to accept the idea of tabs that wrap to more lines in other dimensions.

Of course you can achieve a horizontal scrolling area with white-space: nowrap trick but the scrollbars look ugly on desktops so you have to write js code and the whole thing starts becoming no trivial at all!

I ran into the same issue today, try running ur container with this command.

docker run --name mariadbtest -p 3306:3306 -e MYSQL_ROOT_PASSWORD=mypass -d mariadb/server:10.3

I would simply write each line to a file, since it's already in a CSV format:

write_file = "output.csv"
with open(write_file, "w") as output:
    for line in text:
        output.write(line + '\n')

I can't recall how to write lines with line-breaks at the moment, though :p

Also, you might like to take a look at this answer about write(), writelines(), and '\n'.

My mistake was forgetting single/double quotation around url in javascript:

so wrong code was:

window.location = https://google.com;

and correct code:

window.location = "https://google.com";

My problem was when my fellow developer added a pod in the project and then i pull the project using github then the error occurred. I ran pod install and it updated the pods with new library which was added by my fellow developer. hope it helps.

In C# v.7 you could use an inline out parameter, without an additional variable declaration:

int.TryParse(TextBoxD1.Text, out int x);

Ran into a similar issue and my problem was that MySQL installed itself configured to run on non-default port. I do not know the reason for that, but to find out which port MySQL is running on, run the following in MySql client:

SHOW GLOBAL VARIABLES LIKE 'PORT';

The other answers set the timezone for all dates in your system. This doesn't always work well if you want to support multiple timezones for your users.

Here's the short version:

<?php
$date = new DateTime("now", new DateTimeZone('America/New_York') );
echo $date->format('Y-m-d H:i:s');

Works in PHP >= 5.2.0

List of supported timezones: php.net/manual/en/timezones.php

Here's a version with an existing time and setting timezone by a user setting

<?php

$usersTimezone = 'America/New_York';
$date = new DateTime( 'Thu, 31 Mar 2011 02:05:59 GMT', new DateTimeZone($usersTimezone) );
echo $date->format('Y-m-d H:i:s');

Here is a more verbose version to show the process a little more clearly

<?php

// Date for a specific date/time:
$date = new DateTime('Thu, 31 Mar 2011 02:05:59 GMT');

// Output date (as-is)
echo $date->format('l, F j Y g:i:s A');     

// Output line break (for testing)
echo "\n<br />\n";

// Example user timezone (to show it can be used dynamically)
$usersTimezone = 'America/New_York';

// Convert timezone
$tz = new DateTimeZone($usersTimezone);
$date->setTimeZone($tz);

// Output date after 
echo $date->format('l, F j Y g:i:s A');

Libraries

• Carbon — A very popular date library.
• Chronos — A drop-in replacement for Carbon focused on immutability. See below on why that's important.
• jenssegers/date — An extension of Carbon that adds multi-language support.

I'm sure there are a number of other libraries available, but these are a few I'm familiar with.

Bonus Lesson: Immutable Date Objects

While you're here, let me save you some future headache. Let's say you want to calculate 1 week from today and 2 weeks from today. You might write some code like:

<?php

// Create a datetime (now, in this case 2017-Feb-11)
$today = new DateTime();

echo $today->format('Y-m-d') . "\n<br>";
echo "---\n<br>";

$oneWeekFromToday = $today->add(DateInterval::createFromDateString('7 days'));
$twoWeeksFromToday = $today->add(DateInterval::createFromDateString('14 days'));

echo $today->format('Y-m-d') . "\n<br>";
echo $oneWeekFromToday->format('Y-m-d') . "\n<br>";
echo $twoWeeksFromToday->format('Y-m-d') . "\n<br>";
echo "\n<br>";

The output:

2017-02-11 
--- 
2017-03-04 
2017-03-04 
2017-03-04

Hmmmm... That's not quite what we wanted. Modifying a traditional DateTime object in PHP not only returns the updated date but modifies the original object as well.

This is where DateTimeImmutable comes in.

$today = new DateTimeImmutable();

echo $today->format('Y-m-d') . "\n<br>";
echo "---\n<br>";

$oneWeekFromToday = $today->add(DateInterval::createFromDateString('7 days'));
$twoWeeksFromToday = $today->add(DateInterval::createFromDateString('14 days'));

echo $today->format('Y-m-d') . "\n<br>";
echo $oneWeekFromToday->format('Y-m-d') . "\n<br>";
echo $twoWeeksFromToday->format('Y-m-d') . "\n<br>";

The output:

2017-02-11 
---

In this second example, we get the dates we expected back. By using DateTimeImmutable instead of DateTime, we prevent accidental state mutations and prevent potential bugs.

I had a similar issue, but it turns out I was just referencing a cell which was off the page {i.e. cells(i,1).cut cells (i-1,2)}

As also noted by John Szakmeister and VasiliNovikov, the shortest command to get the full diff from master's perspective on your branch is:

git diff master...

This uses your local copy of master.

To compare a specific file use:

git diff master... filepath

Output example:

As of November 17, 2015. This rule has officially changed. Instagram has deprecated the rule against using their API to upload images.

Good luck.

You'll need some sort of uniquely identifying column in your table, like an auto-filling primary key or a datetime column (preferably the primary key). Then you can do this:

SELECT * FROM table_name ORDER BY unique_column DESC LIMIT 1

The ORDER BY column tells it to rearange the results according to that column's data, and the DESC tells it to reverse the results (thus putting the last one first). After that, the LIMIT 1 tells it to only pass back one row.

Each row in /proc/$PID/maps describes a region of contiguous virtual memory in a process or thread. Each row has the following fields:

address           perms offset  dev   inode   pathname
08048000-08056000 r-xp 00000000 03:0c 64593   /usr/sbin/gpm

• address - This is the starting and ending address of the region in the process's address space
• permissions - This describes how pages in the region can be accessed. There are four different permissions: read, write, execute, and shared. If read/write/execute are disabled, a - will appear instead of the r/w/x. If a region is not shared, it is private, so a p will appear instead of an s. If the process attempts to access memory in a way that is not permitted, a segmentation fault is generated. Permissions can be changed using the mprotect system call.
• offset - If the region was mapped from a file (using mmap), this is the offset in the file where the mapping begins. If the memory was not mapped from a file, it's just 0.
• device - If the region was mapped from a file, this is the major and minor device number (in hex) where the file lives.
• inode - If the region was mapped from a file, this is the file number.
• pathname - If the region was mapped from a file, this is the name of the file. This field is blank for anonymous mapped regions. There are also special regions with names like [heap], [stack], or [vdso]. [vdso] stands for virtual dynamic shared object. It's used by system calls to switch to kernel mode. Here's a good article about it: "What is linux-gate.so.1?"

You might notice a lot of anonymous regions. These are usually created by mmap but are not attached to any file. They are used for a lot of miscellaneous things like shared memory or buffers not allocated on the heap. For instance, I think the pthread library uses anonymous mapped regions as stacks for new threads.

Note that as of Microsoft SQL Server 2016, UTF-8 is supported by bcp, BULK_INSERT, and OPENROWSET.

Addendum 2016-12-21: SQL Server 2016 SP1 now enables Unicode Compression (and most other previously Enterprise-only features) for all versions of MS SQL including Standard and Express. This is not the same as UTF-8 support, but it yields a similar benefit if the goal is disk space reduction for Western alphabets.

You have to properly understand what is a "stdafx.h", aka precompiled header. Other questions or Wikipedia will answer that. In many cases a precompiled header can be avoided, especially if your project is small and with few dependencies. In your case, as you probably started from a template project, it was used to include Windows.h only for the _TCHAR macro.

Then, precompiled header is usually a per-project file in Visual Studio world, so:

1. Ensure you have the file "stdafx.h" in your project. If you don't (e.g. you removed it) just create a new temporary project and copy the default one from there;
2. Change the #include <stdafx.h> to #include "stdafx.h". It is supposed to be a project local file, not to be resolved in include directories.

Secondly: it's inadvisable to include the precompiled header in your own headers, to not clutter namespace of other source that can use your code as a library, so completely remove its inclusion in vector.h.

A good idea is to set all of the "" (blank cells) to NA before any further analysis.

If you are reading your input from a file, it is a good choice to cast all "" to NAs:

foo <- read.table(file="Your_file.txt", na.strings=c("", "NA"), sep="\t") # if your file is tab delimited

If you have already your table loaded, you can act as follows:

foo[foo==""] <- NA

Then to keep only rows with no NA you may just use na.omit():

foo <- na.omit(foo)

Or to keep columns with no NA:

foo <- foo[, colSums(is.na(foo)) == 0] 

You could use

Calendar cal = Calendar.getInstance();
cal.setTime(beginupd);
long millis = cal.getTimeInMillis();

No.

The content-type should be whatever it is known to be, if you know it. application/octet-stream is defined as "arbitrary binary data" in RFC 2046, and there's a definite overlap here of it being appropriate for entities whose sole intended purpose is to be saved to disk, and from that point on be outside of anything "webby". Or to look at it from another direction; the only thing one can safely do with application/octet-stream is to save it to file and hope someone else knows what it's for.

You can combine the use of Content-Disposition with other content-types, such as image/png or even text/html to indicate you want saving rather than display. It used to be the case that some browsers would ignore it in the case of text/html but I think this was some long time ago at this point (and I'm going to bed soon so I'm not going to start testing a whole bunch of browsers right now; maybe later).

RFC 2616 also mentions the possibility of extension tokens, and these days most browsers recognise inline to mean you do want the entity displayed if possible (that is, if it's a type the browser knows how to display, otherwise it's got no choice in the matter). This is of course the default behaviour anyway, but it means that you can include the filename part of the header, which browsers will use (perhaps with some adjustment so file-extensions match local system norms for the content-type in question, perhaps not) as the suggestion if the user tries to save.

Hence:

Content-Type: application/octet-stream
Content-Disposition: attachment; filename="picture.png"

Means "I don't know what the hell this is. Please save it as a file, preferably named picture.png".

Content-Type: image/png
Content-Disposition: attachment; filename="picture.png"

Means "This is a PNG image. Please save it as a file, preferably named picture.png".

Content-Type: image/png
Content-Disposition: inline; filename="picture.png"

Means "This is a PNG image. Please display it unless you don't know how to display PNG images. Otherwise, or if the user chooses to save it, we recommend the name picture.png for the file you save it as".

Of those browsers that recognise inline some would always use it, while others would use it if the user had selected "save link as" but not if they'd selected "save" while viewing (or at least IE used to be like that, it may have changed some years ago).

Simplified:

• Static linking: one large executable
• Dynamic linking: a small executable plus one or more library files (.dll files on Windows, .so on Linux, or .dylib on macOS)

Instead of using a PreferenceActivity to directly load preferences, use an AppCompatActivity or equivalent that loads a PreferenceFragmentCompat that loads your preferences. It's part of the support library (now Android Jetpack) and provides compatibility back to API 14.

In your build.gradle, add a dependency for the preference support library:

dependencies {
    // ...
    implementation "androidx.preference:preference:1.0.0-alpha1"
}

Note: We're going to assume you have your preferences XML already created.

For your activity, create a new activity class. If you're using material themes, you should extend an AppCompatActivity, but you can be flexible with this:

public class MyPreferencesActivity extends AppCompatActivity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.my_preferences_activity)
        if (savedInstanceState == null) {
            getSupportFragmentManager().beginTransaction()
                    .replace(R.id.fragment_container, MyPreferencesFragment())
                    .commitNow()
        }
    }
}

Now for the important part: create a fragment that loads your preferences from XML:

public class MyPreferencesFragment extends PreferenceFragmentCompat {

    @Override
    public void onCreatePreferences(Bundle savedInstanceState, String rootKey) {
        setPreferencesFromResource(R.xml.my_preferences_fragment); // Your preferences fragment
    }
}

For more information, read the Android Developers docs for PreferenceFragmentCompat.

This is the easiest way to do it: http://jsfiddle.net/thirtydot/jwJBd/

(or with table-layout: fixed for even width distribution: http://jsfiddle.net/thirtydot/jwJBd/59/)

This won't work in IE7.

#horizontal-style {
    display: table;
    width: 100%;
    /*table-layout: fixed;*/
}
#horizontal-style li {
    display: table-cell;
}
#horizontal-style a {
    display: block;
    border: 1px solid red;
    text-align: center;
    margin: 0 5px;
    background: #999;
}

_{Old answer before your edit: http://jsfiddle.net/thirtydot/DsqWr/}

Its 2020 and lots of you will come here looking for a similar solution but with Hooks ( They are great! ) and with latest approaches in terms of code cleanliness and syntax.

So as previous answers had stated, the best approach to this kind of problem is to hold the state outside of child component fieldEditor. You could do that in multiple ways.

The most "complex" is with global context (state) that both parent and children could access and modify. Its a great solution when components are very deep in the tree hierarchy and so its costly to send props in each level.

In this case I think its not worth it, and more simple approach will bring us the results we want, just using the powerful React.useState().

Approach with React.useState() hook, way simpler than with Class components

As said we will deal with changes and store the data of our child component fieldEditor in our parent fieldForm. To do that we will send a reference to the function that will deal and apply the changes to the fieldForm state, you could do that with:

function FieldForm({ fields }) {
  const [fieldsValues, setFieldsValues] = React.useState({});
  const handleChange = (event, fieldId) => {
    let newFields = { ...fieldsValues };
    newFields[fieldId] = event.target.value;

    setFieldsValues(newFields);
  };

  return (
    <div>
      {fields.map(field => (
        <FieldEditor
          key={field}
          id={field}
          handleChange={handleChange}
          value={fieldsValues[field]}
        />
      ))}
      <div>{JSON.stringify(fieldsValues)}</div>
    </div>
  );
}

Note that React.useState({}) will return an array with position 0 being the value specified on call (Empty object in this case), and position 1 being the reference to the function that modifies the value.

Now with the child component, FieldEditor, you don't even need to create a function with a return statement, a lean constant with an arrow function will do!

const FieldEditor = ({ id, value, handleChange }) => (
  <div className="field-editor">
    <input onChange={event => handleChange(event, id)} value={value} />
  </div>
);

Aaaaand we are done, nothing more, with just these two slime functional components we have our end goal "access" our child FieldEditor value and show it off in our parent.

You could check the accepted answer from 5 years ago and see how Hooks made React code leaner (By a lot!).

Hope my answer helps you learn and understand more about Hooks, and if you want to check a working example here it is.

loadXMLDoc JS function should return false, otherwise it will result in postback.

Here are conversion method for both ways. this = instance of your class

public string ToXML()
    {
        using(var stringwriter = new System.IO.StringWriter())
        { 
            var serializer = new XmlSerializer(this.GetType());
            serializer.Serialize(stringwriter, this);
            return stringwriter.ToString();
        }
    }

 public static YourClass LoadFromXMLString(string xmlText)
    {
        using(var stringReader = new System.IO.StringReader(xmlText))
        {
            var serializer = new XmlSerializer(typeof(YourClass ));
            return serializer.Deserialize(stringReader) as YourClass ;
        }
    }

The fastest way is to check if there is a non letter:

if (!/[^a-zA-Z]/.test(word))

If we're going to be as sloppy as to use tolower(), do this:

char blah[] = "blah blah Blah BLAH blAH\0"; int i=0; while(blah[i]|=' ', blah[++i]) {}

But, well, it kinda explodes if you feed it some symbols/numerals, and in general it's evil. Good interview question, though.

With ES6 you can now do it like this

Example Codepen URl to load

const iframe = '<iframe height="265" style="width: 100%;" scrolling="no" title="fx." src="//codepen.io/ycw/embed/JqwbQw/?height=265&theme-id=0&default-tab=js,result" frameborder="no" allowtransparency="true" allowfullscreen="true">See the Pen <a href="https://codepen.io/ycw/pen/JqwbQw/">fx.</a> by ycw(<a href="https://codepen.io/ycw">@ycw</a>) on <a href="https://codepen.io">CodePen</a>.</iframe>'; 

A function component to load Iframe

function Iframe(props) {
  return (<div dangerouslySetInnerHTML={ {__html:  props.iframe?props.iframe:""}} />);
}

Usage:

import React from "react";
import ReactDOM from "react-dom";
function App() {
  return (
    <div className="App">
      <h1>Iframe Demo</h1>
      <Iframe iframe={iframe} />,
    </div>
  );
}

const rootElement = document.getElementById("root");
ReactDOM.render(<App />, rootElement);

Edit on CodeSandbox:

https://codesandbox.io/s/react-iframe-demo-g3vst

It is simple: if recv() returns 0 bytes; you will not receive any more data on this connection. Ever. You still might be able to send.

It means that your non-blocking socket have to raise an exception (it might be system-dependent) if no data is available but the connection is still alive (the other end may send).

request.getContextPath()- returns root path of your application, while ../ - returns parent directory of a file.

You use request.getContextPath(), as it will always points to root of your application. If you were to move your jsp file from one directory to another, nothing needs to be changed. Now, consider the second approach. If you were to move your jsp files from one folder to another, you'd have to make changes at every location where you are referring your files.

Also, better approach of using request.getContextPath() will be to set 'request.getContextPath()' in a variable and use that variable for referring your path.

<c:set var="context" value="${pageContext.request.contextPath}" />
<script src="${context}/themes/js/jquery.js"></script>

PS- This is the one reason I can figure out. Don't know if there is any more significance to it.

here the link to webreports version 12 https://www.nuget.org/packages/Microsoft.ReportViewer.WebForms.v12/12.0.0?_src=template

after the package installed

on your toolbox browse the dll reference it to bin then that's it run the visual studio

Considere use DataBindingComplete event for update the style. The next code change the style of the cell:

    private void Grid_DataBindingComplete(object sender, DataGridViewBindingCompleteEventArgs e)
    {
        this.Grid.Rows[2].Cells[1].Style.BackColor = Color.Green;
    }

Let's make a Go 1-compatible list of all the ways to read and write files in Go.

Because file API has changed recently and most other answers don't work with Go 1. They also miss bufio which is important IMHO.

In the following examples I copy a file by reading from it and writing to the destination file.

Start with the basics

package main

import (
    "io"
    "os"
)

func main() {
    // open input file
    fi, err := os.Open("input.txt")
    if err != nil {
        panic(err)
    }
    // close fi on exit and check for its returned error
    defer func() {
        if err := fi.Close(); err != nil {
            panic(err)
        }
    }()

    // open output file
    fo, err := os.Create("output.txt")
    if err != nil {
        panic(err)
    }
    // close fo on exit and check for its returned error
    defer func() {
        if err := fo.Close(); err != nil {
            panic(err)
        }
    }()

    // make a buffer to keep chunks that are read
    buf := make([]byte, 1024)
    for {
        // read a chunk
        n, err := fi.Read(buf)
        if err != nil && err != io.EOF {
            panic(err)
        }
        if n == 0 {
            break
        }

        // write a chunk
        if _, err := fo.Write(buf[:n]); err != nil {
            panic(err)
        }
    }
}

Here I used os.Open and os.Create which are convenient wrappers around os.OpenFile. We usually don't need to call OpenFile directly.

Notice treating EOF. Read tries to fill buf on each call, and returns io.EOF as error if it reaches end of file in doing so. In this case buf will still hold data. Consequent calls to Read returns zero as the number of bytes read and same io.EOF as error. Any other error will lead to a panic.

Using bufio

package main

import (
    "bufio"
    "io"
    "os"
)

func main() {
    // open input file
    fi, err := os.Open("input.txt")
    if err != nil {
        panic(err)
    }
    // close fi on exit and check for its returned error
    defer func() {
        if err := fi.Close(); err != nil {
            panic(err)
        }
    }()
    // make a read buffer
    r := bufio.NewReader(fi)

    // open output file
    fo, err := os.Create("output.txt")
    if err != nil {
        panic(err)
    }
    // close fo on exit and check for its returned error
    defer func() {
        if err := fo.Close(); err != nil {
            panic(err)
        }
    }()
    // make a write buffer
    w := bufio.NewWriter(fo)

    // make a buffer to keep chunks that are read
    buf := make([]byte, 1024)
    for {
        // read a chunk
        n, err := r.Read(buf)
        if err != nil && err != io.EOF {
            panic(err)
        }
        if n == 0 {
            break
        }

        // write a chunk
        if _, err := w.Write(buf[:n]); err != nil {
            panic(err)
        }
    }

    if err = w.Flush(); err != nil {
        panic(err)
    }
}

bufio is just acting as a buffer here, because we don't have much to do with data. In most other situations (specially with text files) bufio is very useful by giving us a nice API for reading and writing easily and flexibly, while it handles buffering behind the scenes.

Note: The following code is for older Go versions (Go 1.15 and before). Things have changed. For the new way, take a look at this answer.

Using ioutil

package main

import (
    "io/ioutil"
)

func main() {
    // read the whole file at once
    b, err := ioutil.ReadFile("input.txt")
    if err != nil {
        panic(err)
    }

    // write the whole body at once
    err = ioutil.WriteFile("output.txt", b, 0644)
    if err != nil {
        panic(err)
    }
}

Easy as pie! But use it only if you're sure you're not dealing with big files.

What C needed was a better preprocessor. cfront was one and thus born c++

I'ld use C, where the 'c++ as preprocessor' would not be okay.

I'm pretty sure, at the bottom of any well written c++ library/framework/toolkit, you would find dirty-old-c ( or static casts, which is same )

Use mysqli instead of mysql, and you need to pass the database name or schema:

before:

$conn = mysql_connect($dbhost, $dbuser, $dbpass);

after:

$conn = mysql_connect($dbhost, $dbuser, $dbpass, $myDBname);

While other answers provide detailed solutions for various setups, this might help someone who is just looking for a general answer.

There are three general options, pick one or more:

1. On the client side, delete the cookie from the browser using javascript.

2. On the server side, set the cookie value to an empty string or something useless (for example "deleted"), and set the cookie expiration time to a time in the past.

3. On the server side, update the refreshtoken stored in your database. Use this option to log out the user from all devices where they are logged in (their refreshtokens will become invalid and they have to log in again).

It is possible to use the host_name() function

select HOST_NAME()

If you start out with:

let array = [
    {name: "malcom", dogType: "four-legged"},
    {name: "peabody", dogType: "three-legged"},
    {name: "pablo", dogType: "two-legged"}
];

And you want a set of, say, names, you would do:

let namesSet = new Set(array.map(item => item.name));

Solution

mylist = [1, 6, 7, 8, 1, 10, 15, 9]
print(mylist)
n = len(mylist)
for i in range(n):
    for j in range(1, n-i):
        if mylist[j-1] > mylist[j]:
             (mylist[j-1], mylist[j]) = (mylist[j], mylist[j-1])
print(mylist)

you can try this.

data_you_need=pd.DataFrame()
for infile in glob.glob("*.xlsx"):
    data = pandas.read_excel(infile)
    data_you_need=data_you_need.append(data,ignore_index=True)

I hope it can help.

There are multiple possible causes for this error:

1) When you put the property 'x' inside brackets you are trying to bind to it. Therefore first thing to check is if the property 'x' is defined in your component with an Input() decorator

Your html file:

<body [x]="...">

Your class file:

export class YourComponentClass {

  @Input()
  x: string;
  ...
}

(make sure you also have the parentheses)

2) Make sure you registered your component/directive/pipe classes in NgModule:

@NgModule({
  ...
  declarations: [
    ...,
    YourComponentClass
  ],
  ...
})

See https://angular.io/guide/ngmodule#declare-directives for more details about declare directives.

3) Also happens if you have a typo in your angular directive. For example:

<div *ngif="...">
     ^^^^^

Instead of:

<div *ngIf="...">

This happens because under the hood angular converts the asterisk syntax to:

<div [ngIf]="...">

• \s matches any white-space character
• \S matches any non-white-space character
• You can match a space character with just the space character;
• [^ ] matches anything but a space character.

Pick whichever is most appropriate.

In my case it was happening during json serialization of a web api return payload - I had a 'circular' reference in my Entity Framework model, I was returning a simple one-to-many object graph back but the child had a reference back to the parent, which apparently the json serializer doensn't like. Removing the property on the child that was referencing the parent did the trick.

Hope this helps someone who might have a similar issue.

simply add to your data structure ( mItems ) , and then notify your adapter about dataset change

private void addItem(String item) {
  mItems.add(item);
  mAdapter.notifyDataSetChanged();
}

addItem("New Item");

You can use _.omit() for emitting the key from a JSON array if you have fewer objects:

_.forEach(data, (d) => {
    _.omit(d, ['keyToEmit1', 'keyToEmit2'])
});

If you have more objects, you can use the reverse of it which is _.pick():

_.forEach(data, (d) => {
    _.pick(d, ['keyToPick1', 'keyToPick2'])
});

For me WORKSPACE was a valid property of the pipeline itself. So when I handed over this to a Groovy method as parameter context from the pipeline script itself, I was able to access the correct value using "... ${context.WORKSPACE} ..."

(on Jenkins 2.222.3, Build Pipeline Plugin 1.5.8, Pipeline: Nodes and Processes 2.35)

You want to make the format/style explicit and don't rely on interpretation based on local settings (which may vary among your clients infrastructure).

DECLARE @Test AS DATETIME
SET @Test = CONVERT(DATETIME, '2011-02-15 00:00:00', 120) -- yyyy-MM-dd hh:mm:ss
SELECT @Test

While there is a plethora of styles, you may want to remember few

• 126 (ISO 8601): yyyy-MM-ddThh:mm:ss(.mmm)
• 120: yyyy-MM-dd hh:mm:ss
• 112: yyyyMMdd

Note that the T in the ISO 8601 is actually the letter T and not a variable.

Here is another example you can try

private void dataGridView_CellContentClick(object sender, DataGridViewCellEventArgs e)
    {
        if (e.ColumnIndex == dataGridView.Columns["Select"].Index)
        {
            dataGridView.EndEdit();

            if ((bool)dataGridView.Rows[e.RowIndex].Cells["Select"].Value)
            {
                //-- checking current select, needs to uncheck any other cells that are checked
                foreach(DataGridViewRow row in dataGridView.Rows)
                {
                    if (row.Index == e.RowIndex)
                    {
                        dataGridView.Rows[row.Index].SetValues(true);
                    }
                    else
                    {
                        dataGridView.Rows[row.Index].SetValues(false);
                    }
                }
            }
        }
    }

Yet another .NET call to quickly authenticate LDAP credentials:

using System.DirectoryServices;

using(var DE = new DirectoryEntry(path, username, password)
{
    try
    {
        DE.RefreshCache(); // This will force credentials validation
    }
    catch (COMException ex)
    {
        // Validation failed - handle how you want
    }
}

The most of the above given examples create a problem when a year has 53 weeks (like 2020). So every fourth year you will experience a week difference. This code does not:

$thisYear = "2020";
$thisDate = "2020-04-24"; //or any other custom date
$weeknr = date("W", strtotime($thisDate)); //when you want the weeknumber of a specific week, or just enter the weeknumber yourself

$tempDatum = new DateTime();
$tempDatum->setISODate($thisYear, $weeknr);
$tempDatum_start = $tempDatum->format('Y-m-d');
$tempDatum->setISODate($thisYear, $weeknr, 7);
$tempDatum_end = $tempDatum->format('Y-m-d');

echo $tempDatum_start //will output the date of monday
echo $tempDatum_end // will output the date of sunday

If you have pointers to parent nodes, you can do it without additional memory.

def dfs(root):
    node = root
    while True:
        visit(node)
        if node.first_child:
            node = node.first_child      # walk down
        else:
            while not node.next_sibling:
                if node is root:
                    return
                node = node.parent       # walk up ...
            node = node.next_sibling     # ... and right

Note that if the child nodes are stored as an array rather than through sibling pointers, the next sibling can be found as:

def next_sibling(node):
    try:
        i =    node.parent.child_nodes.index(node)
        return node.parent.child_nodes[i+1]
    except (IndexError, AttributeError):
        return None

Most of these answers circulate around removing a file from the "staging area" pre-commit, but I often find myself looking here after I've already committed and I want to remove some sensitive information from the commit I just made.

An easy to remember trick for all of you git commit --amend folks out there like me is that you can:

1. Delete the accidentally committed file.
2. git add . to add the deletion to the "staging area"
3. git commit --amend to remove the file from the previous commit.

You will notice in the commit message that the unwanted file is now missing. Hooray! (Commit SHA will have changed, so be careful if you already pushed your changes to the remote.)

Usually, I work with DATE columns, not the larger but more precise TIMESTAMP used by some answers.

The following will return the current UTC date as just that -- a DATE.

CAST(sys_extract_utc(SYSTIMESTAMP) AS DATE)

I often store dates like this, usually with the field name ending in _UTC to make it clear for the developer. This allows me to avoid the complexity of time zones until last-minute conversion by the user's client. Oracle can store time zone detail with some data types, but those types require more table space than DATE, and knowledge of the original time zone is not always required.

As apps run in the background anyway. I’m assuming what your really asking is how do you make apps do stuff in the background. The solution below will make your app do stuff in the background after opening the app and after the system has rebooted.

Below, I’ve added a link to a fully working example (in the form of an Android Studio Project)

This subject seems to be out of the scope of the Android docs, and there doesn’t seem to be any one comprehensive doc on this. The information is spread across a few docs.

The following docs tell you indirectly how to do this: https://developer.android.com/reference/android/app/Service.html

https://developer.android.com/reference/android/content/BroadcastReceiver.html

https://developer.android.com/guide/components/bound-services.html

In the interests of getting your usage requirements correct, the important part of this above doc to read carefully is: #Binder, #Messenger and the components link below:

https://developer.android.com/guide/components/aidl.html

Here is the link to a fully working example (in Android Studio format): http://developersfound.com/BackgroundServiceDemo.zip

This project will start an Activity which binds to a service; implementing the AIDL.

This project is also useful to re-factor for the purpose of IPC across different apps.

This project is also developed to start automatically when Android restarts (provided the app has been run at least one after installation and app is not installed on SD card)

When this app/project runs after reboot, it dynamically uses a transparent view to make it look like no app has started but the service of the associated app starts cleanly.

This code is written in such a way that it’s very easy to tweak to simulate a scheduled service.

This project is developed in accordance to the above docs and is subsequently a clean solution.

There is however a part of this project which is not clean being: I have not found a way to start a service on reboot without using an Activity. If any of you guys reading this post have a clean way to do this please post a comment.

Delimiters other than the default ; are typically used when defining functions, stored procedures, and triggers wherein you must define multiple statements. You define a different delimiter like $$ which is used to define the end of the entire procedure, but inside it, individual statements are each terminated by ;. That way, when the code is run in the mysql client, the client can tell where the entire procedure ends and execute it as a unit rather than executing the individual statements inside.

Note that the DELIMITER keyword is a function of the command line mysql client (and some other clients) only and not a regular MySQL language feature. It won't work if you tried to pass it through a programming language API to MySQL. Some other clients like PHPMyAdmin have other methods to specify a non-default delimiter.

Example:

DELIMITER $$
/* This is a complete statement, not part of the procedure, so use the custom delimiter $$ */
DROP PROCEDURE my_procedure$$

/* Now start the procedure code */
CREATE PROCEDURE my_procedure ()
BEGIN    
  /* Inside the procedure, individual statements terminate with ; */
  CREATE TABLE tablea (
     col1 INT,
     col2 INT
  );

  INSERT INTO tablea
    SELECT * FROM table1;

  CREATE TABLE tableb (
     col1 INT,
     col2 INT
  );
  INSERT INTO tableb
    SELECT * FROM table2;
  
/* whole procedure ends with the custom delimiter */
END$$

/* Finally, reset the delimiter to the default ; */
DELIMITER ;

Attempting to use DELIMITER with a client that doesn't support it will cause it to be sent to the server, which will report a syntax error. For example, using PHP and MySQLi:

$mysqli = new mysqli('localhost', 'user', 'pass', 'test');
$result = $mysqli->query('DELIMITER $$');
echo $mysqli->error;

Errors with:

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'DELIMITER $$' at line 1

This error may occur when your certificate has expired.

The solution is to renew certificate and sign the application with it.

This one get everything between the "." characters. Please note this won't work for more complex URLs like "www.somesite.co.uk" Ideally the function would check for how many instances of the "." character and choose the substring accordingly.

CREATE FUNCTION dbo.GetURL (@URL VARCHAR(250))
RETURNS VARCHAR(250)
AS BEGIN
    DECLARE @Work VARCHAR(250)

    SET @Work = @URL

    SET @Work = SUBSTRING(@work, CHARINDEX('.', @work) + 1, LEN(@work))   
    SET @Work = SUBSTRING(@work, 0, CHARINDEX('.', @work))

    --Alternate:
    --SET @Work = SUBSTRING(@work, CHARINDEX('.', @work) + 1, CHARINDEX('.', @work) + 1)   

    RETURN @work
END

My solution is to run twine upload over the python -m argument.

So just use python -m:

python -m twine upload dist/*

I'm not sure what your problem is (since you haven't told us), but I'm guessing at

a = Console.Read();

This will only read one character from your Console.

You can change your program to this. To make it more robust, accept more than 1 char input, and validate that the input is actually a number:

double a, b;
Console.WriteLine("istenen sayiyi sonuna .00 koyarak yaz");
if (double.TryParse(Console.ReadLine(), out a)) {
  b = a * Math.PI;
  Console.WriteLine("Sonuç " + b); 
} else {
  //user gave an illegal input. Handle it here.
}

This will -

• Resize width AND height without the need for a loop
• Doesn't exceed the images original dimensions

//////////////

private void ResizeImage(Image img, double maxWidth, double maxHeight)
{
    double resizeWidth = img.Source.Width;
    double resizeHeight = img.Source.Height;

    double aspect = resizeWidth / resizeHeight;

    if (resizeWidth > maxWidth)
    {
        resizeWidth = maxWidth;
        resizeHeight = resizeWidth / aspect;
    }
    if (resizeHeight > maxHeight)
    {
        aspect = resizeWidth / resizeHeight;
        resizeHeight = maxHeight;
        resizeWidth = resizeHeight * aspect;
    }

    img.Width = resizeWidth;
    img.Height = resizeHeight;
}

An alternative to darindaCoder's answer:

path = r'C:\DRO\DCL_rawdata_files'                     # use your path
all_files = glob.glob(os.path.join(path, "*.csv"))     # advisable to use os.path.join as this makes concatenation OS independent

df_from_each_file = (pd.read_csv(f) for f in all_files)
concatenated_df   = pd.concat(df_from_each_file, ignore_index=True)
# doesn't create a list, nor does it append to one

Oracle as well as modern versions of Ubuntu have moved to newer versions of Java. The default for Ubuntu 20.04 is OpenJDK 11 which is good enough for most purposes.

If you really need it for running legacy programs, OpenJDK 8 is also available for Ubuntu 20.04 from the official repositories.

If you really need exactly Java 7, the best bet as of 2020 is to download a Zulu distribution. The easiest to install if you have root privileges is the .DEB version, otherwise download the .ZIP one.

Hope this code will help

public class ThisFragment extends Fragment {

public Button button = null;
Intent intent;

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

    View rootView = inflater.inflate(R.layout.yourlayout, container, false);

    intent = new Intent(getActivity(), GoToThisActivity.class);
    button = (Button) rootView.findViewById(R.id.theButtonid);
    button.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            startActivity(intent);
        }
    });
    return rootView;
}

You can use this code, make sure you change "ThisFragment" as your fragment name, "yourlayout" as the layout name, "GoToThisActivity" change it to which activity do you want and then "theButtonid" change it with your button id you used.

Use SimpleCrypto

Using encrypt() and decrypt()

To use SimpleCrypto, first create a SimpleCrypto instance with a secret key (password). Secret key parameter MUST be defined when creating a SimpleCrypto instance.

To encrypt and decrypt data, simply use encrypt() and decrypt() function from an instance. This will use AES-CBC encryption algorithm.

var _secretKey = "some-unique-key";

var simpleCrypto = new SimpleCrypto(_secretKey);

var plainText = "Hello World!";
var chiperText = simpleCrypto.encrypt(plainText);
console.log("Encryption process...");
console.log("Plain Text    : " + plainText);
console.log("Cipher Text   : " + cipherText);
var decipherText = simpleCrypto.decrypt(cipherText);
console.log("... and then decryption...");
console.log("Decipher Text : " + decipherText);
console.log("... done.");

Application.SetOption "Auto compact", False '(mentioned above) Use this with a button caption: "DB Not Compact On Close"

Write code to toggle the caption with "DB Compact On Close" along with Application.SetOption "Auto compact", True

AutoCompact can be set by means of the button or by code, ex: after importing large temp tables.

The start up form can have code that turns off Auto Compact, so that it doesn't run every time.

This way, you are not trying to fight Access.

Sorry for adding another answer to an old post but I usually get a scroll event very well by using this code (it works at least on 6.1)

element.addEventListener('scroll', function() {
    console.log(this.scrollTop);
});

// This is the magic, this gives me "live" scroll events
element.addEventListener('gesturechange', function() {});

And that works for me. Only thing it doesn't do is give a scroll event for the deceleration of the scroll (Once the deceleration is complete you get a final scroll event, do as you will with it.) but if you disable inertia with css by doing this

-webkit-overflow-scrolling: none;

You don't get inertia on your elements, for the body though you might have to do the classic

document.addEventListener('touchmove', function(e) {e.preventDefault();}, true);

Found one more way of doing it

 if let parameters = route.parameters {

                    for (key, value) in parameters {
                         if value is String {
                            if let temp = value as? String {
                                multipartFormData.append(temp.description.data(using: .utf8)!, withName: key)
                            }
                        }

                            }
                            else if let temp = value as? [Int]{
                                multipartFormData.append(temp.description.data(using: .utf8)!, withName: key)
                            }
                            else if let temp = value as? [String]{
                                multipartFormData.append(temp.description.data(using: .utf8)!, withName: key)
                            }
                        }
                        else if CFGetTypeID(value as CFTypeRef) == CFNumberGetTypeID() {
                            if let temp = value as? Int {
                                multipartFormData.append(temp.description.data(using: .utf8)!, withName: key)
                            }
                        }
                        else if CFGetTypeID(value as CFTypeRef) == CFBooleanGetTypeID(){
                            if let temp = value as? Bool {
                                multipartFormData.append(temp.description.data(using: .utf8)!, withName: key)
                            }
                        }
                    }
                }

                if let items: [MultipartData] = route.multipartData{
                    for item in items {
                        if let value = item.value{
                            multipartFormData.append(value, withName: item.key, fileName: item.fileName, mimeType: item.mimeType)
                        }
                    }
                }

Just Define following lines at top of your Database SQL file.

SET SQL_MODE = "NO_AUTO_VALUE_ON_ZERO";
SET time_zone = "+00:00";

It is working for me.

Another way to check if given URL is valid is to try to access it, below function will fetch the headers from given URL, this will ensure that URL is valid AND web server is alive:

function is_url($url){
        $response = array();
        //Check if URL is empty
        if(!empty($url)) {
            $response = get_headers($url);
        }
        return (bool)in_array("HTTP/1.1 200 OK", $response, true);
/*Array
(
    [0] => HTTP/1.1 200 OK 
    [Date] => Sat, 29 May 2004 12:28:14 GMT
    [Server] => Apache/1.3.27 (Unix)  (Red-Hat/Linux)
    [Last-Modified] => Wed, 08 Jan 2003 23:11:55 GMT
    [ETag] => "3f80f-1b6-3e1cb03b"
    [Accept-Ranges] => bytes
    [Content-Length] => 438
    [Connection] => close
    [Content-Type] => text/html
)*/ 
    }   

Open terminal nano ~/.ssh/id_rsa.pub

I had the same issue and I resolved it by making changes in the UnityConfig.cs file In order to resolve the dependency issue in the UnityConfig.cs file you have to add:

public static void RegisterComponents()    
{
    var container = new UnityContainer();
    container.RegisterType<ITestService, TestService>();
    DependencyResolver.SetResolver(new UnityDependencyResolver(container));
}

The rule is as following :

A B 

B as a descendant of A

A > B 

B as a child of A

So

div.dropdown *

and not

div.dropdown > *

You can call a reset function before appending. Something like this:

    function resetNewReviewBoardForm() {
    $("#Description").val('');
    $("#PersonName").text('');
    $("#members").empty(); //this one what worked in my case
    $("#EmailNotification").val('False');
}

This solves the issue in the appropriate way

// Merge a row
            ws.Cell("B2").Value = "Merged Row(1) of Range (B2:D3)";
            ws.Range("B2:D3").Row(1).Merge();

You can also use JSONObject class from json.org to this will convert your HashMap to JSON string which is well formatted

Example:

Map<String,Object> map = new HashMap<>();
map.put("myNumber", 100);
map.put("myString", "String");

JSONObject json= new JSONObject(map);

String result= json.toString();

System.out.print(result);

result:

{'myNumber':100, 'myString':'String'}

Your can also get key from it like

System.out.print(json.get("myNumber"));

result:

100

git pull -s recursive -X theirs <remoterepo or other repo>

Or, simply, for the default repository:

git pull -X theirs

If you're already in conflicted state...

git checkout --theirs path/to/file

setTimeout(function() { $location.path("/abc"); },0);

it should solve your problem.

Sure, a Linked List is a bit confusing for programming n00bs, pretty much the temptation is to look at it as Russian Dolls, because that's what it seems like, a LinkedList Object in a LinkedList Object. But that's a touch difficult to visualize, instead look at it like a computer.

LinkedList = Data + Next Member

Where it's the last member of the list if next is NULL

So a 5 member LinkedList would be:

LinkedList(Data1, LinkedList(Data2, LinkedList(Data3, LinkedList(Data4, LinkedList(Data5, NULL)))))

But you can think of it as simply:

Data1 -> Data2 -> Data3 -> Data4 -> Data5 -> NULL

So, how do we find the end of this? Well, we know that the NULL is the end so:

public void append(LinkedList myNextNode) {
  LinkedList current = this; //Make a variable to store a pointer to this LinkedList
  while (current.next != NULL) { //While we're not at the last node of the LinkedList
    current = current.next; //Go further down the rabbit hole.
  }
  current.next = myNextNode; //Now we're at the end, so simply replace the NULL with another Linked List!
  return; //and we're done!
}

This is very simple code of course, and it will infinitely loop if you feed it a circularly linked list! But that's the basics.

This helped me:

docker-compose down  # Stop container on current dir if there is a docker-compose.yml
docker rm -fv $(docker ps -aq)  # Remove all containers
sudo lsof -i -P -n | grep <port number>  # List who's using the port

and then: kill -9 <process id> (macOS) or sudo kill <process id> (Linux).

In your head element add

<script type="text/javascript" src="myscript.js"></script>

Same as @Habib's answer, but as a function:

List<int> randomList = new List<int>();
int UniqueRandomInt(int min, int max)
{
    var rand = new Random();
    int myNumber;
    do
    {
       myNumber = rand.Next(min, max);
    } while (randomList.Contains(myNumber));
    return myNumber;
}

If randomList is a class property, UniqueRandomInt will return unique integers in the context of the same instance of that class. If you want it to be unique globally, you will need to make randomList static.

Add cellpadding and cellspacing to solve it. Edit: Also removed double pixel border.

<style>
td
{border-left:1px solid black;
border-top:1px solid black;}
table
{border-right:1px solid black;
border-bottom:1px solid black;}
</style>
<html>
    <body>
        <table cellpadding="0" cellspacing="0">
            <tr>
                <td width="350" >
                    Foo
                </td>
                <td width="80" >
                    Foo1
                </td>
                <td width="65" >
                    Foo2
                </td>
            </tr>
            <tr>
                <td>
                    Bar1

                <td>

If you're using framework 4.0 then the entry in the web.config (<pages validateRequest="false" />)

<configuration>
    <system.web>
        <pages validateRequest="false" />
    </system.web>
</configuration>

If you're using framework 4.5 then the entry in the web.config (requestValidationMode="2.0")

<system.web>
    <compilation debug="true" targetFramework="4.5" />
    <httpRuntime targetFramework="4.5" requestValidationMode="2.0"/>
</system.web>

If you want for only single page then, In you aspx file you should put the first line as this :

<%@ Page EnableEventValidation="false" %>

if you already have something like <%@ Page so just add the rest => EnableEventValidation="false" %>

I recommend not to do it.

You could also try to include md5-hash-sums or similar do determine whether there are any differences at all. Then, only compare files which have different hashes...

use the below command to set the port number in node process while running node JS programme:

set PORT =3000 && node file_name.js

The set port can be accessed in the code as

process.env.PORT 

Routes monitor the $location service and respond to changes in URL (typically through the hash). To "activate" a route, you simply change the URL. The easiest way to do that is with anchor tags.

<a href="#/home">Go Home</a>
<a href="#/about">Go to About</a>

Nothing more complicated is needed. If, however, you must do this from code, the proper way is by using the $location service:

$scope.go = function ( path ) {
  $location.path( path );
};

Which, for example, a button could trigger:

<button ng-click="go('/home')"></button>

I did this;

In controller:

public ActionResult Index()
{
  var invoices = db.Invoices;

  var categories = db.Categories.ToList();
  ViewData["MyData"] = categories; // Send this list to the view

  return View(invoices.ToList());
}

In view:

@model IEnumerable<abc.Models.Invoice>

@{
    ViewBag.Title = "Invoices";
}

@{
  var categories = (List<Category>) ViewData["MyData"]; // Cast the list
}

@foreach (var c in @categories) // Print the list
{
  @Html.Label(c.Name);
}

<table>
    ...
    @foreach (var item in Model) 
    {
      ...
    }
</table>

Hope it helps

I would go like this (regex explained in comments):

import re

# If you need to use the regex more than once it is suggested to compile it.
pattern = re.compile(r"</{0,}\[\d+>")

# <\/{0,}\[\d+>
# 
# Match the character “<” literally «<»
# Match the character “/” literally «\/{0,}»
#    Between zero and unlimited times, as many times as possible, giving back as needed (greedy) «{0,}»
# Match the character “[” literally «\[»
# Match a single digit 0..9 «\d+»
#    Between one and unlimited times, as many times as possible, giving back as needed (greedy) «+»
# Match the character “>” literally «>»

subject = """this is a paragraph with<[1> in between</[1> and then there are cases ... where the<[99> number ranges from 1-100</[99>. 
and there are many other lines in the txt files
with<[3> such tags </[3>"""

result = pattern.sub("", subject)

print(result)

If you want to learn more about regex I recomend to read Regular Expressions Cookbook by Jan Goyvaerts and Steven Levithan.

Use the fnReloadAjax() by the DataTables.net author.

On Ubuntu systems, use the following locations:

1. System-wide persistent variables in the format of JAVA_PATH=/usr/local/java store in

   /etc/environment
   

2. System-wide persistent variables that reference variables such as
   export PATH="$JAVA_PATH:$PATH" store in

   /etc/.bashrc
   

3. User specific persistent variables in the format of PATH DEFAULT=/usr/bin:usr/local/bin store in

   ~/.pam_environment
   

For more details on #2, check this Ask Ubuntu answer. NOTE: #3 is the Ubuntu recommendation but may have security concerns in the real world.

We have a react application and our development machines are both mac and pc. The start command doesn't work for PC so here is how we got around it:

"start": "PORT=3001 react-scripts start",
"start-pc": "set PORT=3001&& react-scripts start",

On my mac:

npm start

On my pc:

 npm run start-pc

I've found that you don't need the serializer at all. If you return the object as a List. Let me use an example.

In our asmx we get the data using the variable we passed along

// return data
[WebMethod(CacheDuration = 180)]
public List<latlon> GetData(int id) 
{
    var data = from p in db.property 
               where p.id == id 
               select new latlon
               {
                   lat = p.lat,
                   lon = p.lon

               };
    return data.ToList();
}

public class latlon
{
    public string lat { get; set; }
    public string lon { get; set; }
}

Then using jquery we access the service, passing along that variable.

// get latlon
function getlatlon(propertyid) {
var mydata;

$.ajax({
    url: "getData.asmx/GetLatLon",
    type: "POST",
    data: "{'id': '" + propertyid + "'}",
    async: false,
    contentType: "application/json;",
    dataType: "json",
    success: function (data, textStatus, jqXHR) { //
        mydata = data;
    },
    error: function (xmlHttpRequest, textStatus, errorThrown) {
        console.log(xmlHttpRequest.responseText);
        console.log(textStatus);
        console.log(errorThrown);
    }
});
return mydata;
}

// call the function with your data
latlondata = getlatlon(id);

And we get our response.

{"d":[{"__type":"MapData+latlon","lat":"40.7031420","lon":"-80.6047970}]}

Adding to Brian Agnew's answer.

You can also do //div[@id='..' or @class='...] and you can have parenthesized expressions inside //div[@id='..' and (@class='a' or @class='b')].

I am not sure if/how browsers scale large icons, but The W3C suggests the following¹:

The format for the image you have chosen must be 16x16 pixels or 32x32 pixels, using either 8-bit or 24-bit colors. The format of the image must be one of PNG (a W3C standard), GIF, or ICO.

¹ w3c.org: How to Add a Favicon to your Site (Draft in development).

In your test, you are comparing the two TestParent beans, not the single TestedChild bean.

Also, Spring proxies your @Configuration class so that when you call one of the @Bean annotated methods, it caches the result and always returns the same object on future calls.

See here:

• How does Spring @Configuration cache references to beans

This will add an image to another.

using (Graphics grfx = Graphics.FromImage(image))
{
    grfx.DrawImage(newImage, x, y)
}

Graphics is in the namespace System.Drawing

To copy formatting:

Range("F10").Select
Selection.Copy
Range("I10:J10").Select ' note that we select the whole merged cell
Selection.PasteSpecial Paste:=xlPasteFormats

copying the formatting will break the merged cells, so you can use this to put the cell back together

Range("I10:J10").Select
Selection.Merge

To copy a cell value, without copying anything else (and not using copy/paste), you can address the cells directly

Range("I10").Value = Range("F10").Value

other properties (font, color, etc ) can also be copied by addressing the range object properties directly in the same way

If the time is 11:03, then the accepted answer will print 11:3.

You could zero-pad the minutes:

"Created at {:d}:{:02d}".format(tdate.hour, tdate.minute)

Or go another way and use tdate.time() and only take the hour/minute part:

str(tdate.time())[0:5]

Using an enhanced for would be even nicer:

int sum = 0;
for (int d : data) sum += d;

Another thing that will probably give you a big surprise is the wrong result that you will obtain from

double average = sum / data.length;

Reason: on the right-hand side you have integer division and Java will not automatically promote it to floating-point division. It will calculate the integer quotient of sum/data.length and only then promote that integer to a double. A solution would be

double average = 1.0d * sum / data.length;

This will force the dividend into a double, which will automatically propagate to the divisor.

On Android 10, none worked for me.

But I that worked perfectly fine (1st line in oncreate):

    View decorView = getWindow().getDecorView();
    int uiOptions = View.SYSTEM_UI_FLAG_IMMERSIVE;
    decorView.setSystemUiVisibility(uiOptions);

    setContentView(....);

    if (getSupportActionBar() != null) {
        getSupportActionBar().hide();
    }

enjoy :)

One of the most straightforward ways to do it is

git for-each-ref --format='%(refname:short)' refs/heads/

This works perfectly for scripts as well.

public static IEnumerable<IEnumerable<T>> Batch<T>(this IEnumerable<T> items, int maxItems)
{
    return items.Select((item, index) => new { item, index })
                .GroupBy(x => x.index / maxItems)
                .Select(g => g.Select(x => x.item));
}

The problems you have are because of the extra <form> you have, that your data goes in GET method, and you are accessing the data in PHP using POST.

<body>
<!--<form>-->
    <form action="myprocessingscript.php" method="POST">

Java does not (yet) support closures. But there are other languages like Scala and Groovy which run in the JVM and do support closures.

I know it's not the asnwer to the precise question (Chrome Developer Tools) but I'm using this workaround with success: http://www.telerik.com/fiddler

(pretty sure some of the web devs already know about this tool)

1. Save the file locally
2. Edit as required
3. Profit!

Full docs: http://docs.telerik.com/fiddler/KnowledgeBase/AutoResponder

PS. I would rather have it implemented in Chrome as a flag preserve after reload, cannot do this now, forums and discussion groups blocked on corporate network :)

Since I don't see any jQuery based solutions that don't require extra libraries here is a simple one that is a bit more flexible than those using fadeIn/fadeOut.

$.fn.blink = function (count) {
    var $this = $(this);

    count = count - 1 || 0;

    $this.animate({opacity: .25}, 100, function () {
        $this.animate({opacity: 1}, 100, function () {
            if (count > 0) {
                $this.blink(count);
            }
        });
    });
};

Use it like this

$('#element').blink(3); // 3 Times.

The error code indicates the function definition cannot be found. Make sure you're calling the function from the same workspace as the divrat.m file is stored. And make sure divrat function is not a subfunction, it should be first function declaration in the file. You can also try to call the function from the same divrat.m file in order to see if the problem is with workspace selection or the function.

By the way, why didn't you simply say

s = sqrt(diag(C));

Wouldn't it be the same?

No one has clearly mentioned this, but this kind of pattern is usually not suited for semaphores. The reason is that any thread can release a semaphore, but you usually only want the owner thread that originally locked to be able to unlock. For this use case, in Java, we usually use ReentrantLocks, which can be created like this:

import java.util.concurrent.locks.Lock;
import java.util.concurrent.locks.ReentrantLock;

private final Lock lock = new ReentrantLock(true);

And the usual design pattern of usage is:

  lock.lock();
  try {
      // do something
  } catch (Exception e) {
      // handle the exception
  } finally {
      lock.unlock();
  }

Here is an example in the java source code where you can see this pattern in action.

Reentrant locks have the added benefit of supporting fairness.

Use semaphores only if you need non-ownership-release semantics.

There's an article over on MSDN that has a sample application for zipping and unzipping files and folders purely in C#. I've been using some of the classes in that successfully for a long time. The code is released under the Microsoft Permissive License, if you need to know that sort of thing.

EDIT: Thanks to Cheeso for pointing out that I'm a bit behind the times. The MSDN example I pointed to is in fact using DotNetZip and is really very fully-featured these days. Based on my experience of a previous version of this I'd happily recommend it.

SharpZipLib is also quite a mature library and is highly rated by people, and is available under the GPL license. It really depends on your zipping needs and how you view the license terms for each of them.

Update to SQL server 2016/2017/…
We have some stored procedures in place to import and export databases.
In the sp we use (amongst other things) RESTORE FILELISTONLY FROM DISK where we create a table "#restoretemp" for the restore from file.

With SQL server 2016, MS has added a field SnapshotURL nvarchar(360) (restore url Azure) what has caused the error message.
After I have enhanced the additional field, the restore has worked again.
Code snipped (see last field):

 SET @query = 'RESTORE FILELISTONLY FROM DISK = ' + QUOTENAME(@BackupFile , '''')
CREATE TABLE #restoretemp
(
LogicalName nvarchar(128)
,PhysicalName nvarchar(128)
,[Type] char(1)
,FileGroupName nvarchar(128)
,[Size] numeric(20,0)
,[MaxSize] numeric(20,0)
,FileID bigint
,CreateLSN numeric(25,0)
,DropLSN numeric(25,0) NULL
,UniqueID uniqueidentifier
,ReadOnlyLSN numeric(25,0)
,ReadWriteLSN numeric(25,0)
,BackupSizeInByte bigint
,SourceBlockSize int
,FilegroupID int
,LogGroupGUID uniqueidentifier NULL

,IsPresent bit
,TDEThumbprint varbinary(32)
-- Added field 01.10.2018 needed from SQL Server 2016 (Azure URL)
,SnapshotURL nvarchar(360)
)

INSERT #restoretemp EXEC (@query)
SET @errorstat = @@ERROR
if @errorstat <> 0 
Begin
if @Rueckgabe = 0 SET @Rueckgabe = 6
End
Print @Rueckgabe

IMHO it is considered as malformed header data.

You actually want to send those name value pairs as the request content (this is the way POST works) and not as headers.

The second way is true.

In addition to registering a ByteArrayHttpMessageConverter, you may want to use a ResponseEntity instead of @ResponseBody. The following code works for me :

@RequestMapping("/photo2")
public ResponseEntity<byte[]> testphoto() throws IOException {
    InputStream in = servletContext.getResourceAsStream("/images/no_image.jpg");

    final HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.IMAGE_PNG);

    return new ResponseEntity<byte[]>(IOUtils.toByteArray(in), headers, HttpStatus.CREATED);
}

Here is a script which generates grant queries for a particular table. It omits owner's privileges.

SELECT 
    format (
      'GRANT %s ON TABLE %I.%I TO %I%s;',
      string_agg(tg.privilege_type, ', '),
      tg.table_schema,
      tg.table_name,
      tg.grantee,
      CASE
        WHEN tg.is_grantable = 'YES' 
        THEN ' WITH GRANT OPTION' 
        ELSE '' 
      END
    )
  FROM information_schema.role_table_grants tg
  JOIN pg_tables t ON t.schemaname = tg.table_schema AND t.tablename = tg.table_name
  WHERE
    tg.table_schema = 'myschema' AND
    tg.table_name='mytable' AND
    t.tableowner <> tg.grantee
  GROUP BY tg.table_schema, tg.table_name, tg.grantee, tg.is_grantable;

I had the same error message when I switched to guest profile in my emulator. I switched back to owner profile and it worked.

an option that worked for me, define the field in the original form as:

forms.CharField(widget = forms.HiddenInput(), required = False)

then when you override it in the new Class it will keep it's place.

Generally the cast operator is preferred to the Class#cast method as it's more concise and can be analyzed by the compiler to spit out blatant issues with the code.

Class#cast takes responsibility for type checking at run-time rather than during compilation.

There are certainly use-cases for Class#cast, particularly when it comes to reflective operations.

Since lambda's came to java I personally like using Class#cast with the collections/stream API if I'm working with abstract types, for example.

Dog findMyDog(String name, Breed breed) {

You are using an $id variable in your model, but your are plucking it from nowhere. You need to pass the $id variable from your controller to your model.

Controller

Lets pass the $id to the model via a parameter of the row_delete() method.

function delete_row()
{
   $this->load->model('mod1');

   // Pass the $id to the row_delete() method
   $this->mod1->row_delete($id);


   redirect($_SERVER['HTTP_REFERER']);  
}

Model

Add the $id to the Model methods parameters.

function row_delete($id)
{
   $this->db->where('id', $id);
   $this->db->delete('testimonials'); 
}

The problem now is that your passing the $id variable from your controller, but it's not declared anywhere in your controller.

There is a much easier way to run Java, no configuration needed:

1. Install the Code Runner Extension
2. Open your Java code file in Text Editor, then use shortcut Ctrl+Alt+N, or press F1 and then select/type Run Code, or right click the Text Editor and then click Run Code in context menu, the code will be compiled and run, and the output will be shown in the Output Window.

If you just deleted the branch, you will see something like this in your terminal:

Deleted branch branch_name(was e562d13)

• where e562d13 is a unique ID (a.k.a. the "SHA" or "hash"), with this you can restore the deleted branch.

To restore the branch, use:

git checkout -b <branch_name> <sha>

for example:

git checkout -b branch_name e562d13 

A quick hack I used which works well:

const monthNumber = 8;_x000D_
const yearNumber = 2018;_x000D_
const date = `${['Jan', 'Feb', 'Mar', 'Apr',_x000D_
  'May', 'Jun', 'Jul', 'Aug',_x000D_
  'Sep', 'Oct', 'Nov', 'Dec'][monthNumber - 1]_x000D_
      } ${yearNumber}`;_x000D_
_x000D_
console.log(date);

This answer is update to Swift 3.

This is how you can add an image view programmatically where you can control the constraints.

Class ViewController: UIViewController {

    let someImageView: UIImageView = {
       let theImageView = UIImageView()
       theImageView.image = UIImage(named: "yourImage.png")
       theImageView.translatesAutoresizingMaskIntoConstraints = false //You need to call this property so the image is added to your view
       return theImageView
    }()

    override func viewDidLoad() {
       super.viewDidLoad()

       view.addSubview(someImageView) //This add it the view controller without constraints
       someImageViewConstraints() //This function is outside the viewDidLoad function that controls the constraints
    }

    // do not forget the `.isActive = true` after every constraint
    func someImageViewConstraints() {
        someImageView.widthAnchor.constraint(equalToConstant: 180).isActive = true
        someImageView.heightAnchor.constraint(equalToConstant: 180).isActive = true
        someImageView.centerXAnchor.constraint(equalTo: view.centerXAnchor).isActive = true
        someImageView.centerYAnchor.constraint(equalTo: view.centerYAnchor, constant: 28).isActive = true
    }

2. Go to Security tab.
3. Either Enable/Disable the protected mode for all(Internet, Local Intranet, Trusted Sites & Restricted Sites.)

Modern processors are too fast to register the running time. Hence it may return zero. In this case, the time you started and ended is too small and therefore both the times are the same after round of.
