Programs & Examples On #Jquery pagination

i had the same problem with my jar the solution

1. Create the MANIFEST.MF file:

Manifest-Version: 1.0

Sealed: true

Class-Path: . lib/jarX1.jar lib/jarX2.jar lib/jarX3.jar

Main-Class: com.MainClass

2. Right click on project, Select Export.

select export all outpout folders for checked project

3. select using existing manifest from workspace and select the MANIFEST.MF file

This worked for me :)

SQLAlchemy's declarative extension, which is becoming standard in 0.5, provides an all in one interface very much like that of Django or Storm. It also integrates seamlessly with classes/tables configured using the datamapper style:

Base = declarative_base()

class Foo(Base):
    __tablename__ = 'foos'
    id = Column(Integer, primary_key=True)

class Thing(Base):
    __tablename__ = 'things'

    id = Column(Integer, primary_key=True)
    name = Column(Unicode)
    description = Column(Unicode)
    foo_id = Column(Integer, ForeignKey('foos.id'))
    foo = relation(Foo)

engine = create_engine('sqlite://')

Base.metadata.create_all(engine)  # issues DDL to create tables

session = sessionmaker(bind=engine)()

foo = Foo()
session.add(foo)
thing = Thing(name='thing1', description='some thing')
thing.foo = foo  # also adds Thing to session
session.commit()

You can create an appropriate table through management studio interface and insert data into the table like it's shown below. It may take some time depending on the amount of data, but it is very handy.

put this in your "head" of your index.html

 <style>
  html body{
    left: 0;
    right: 0;
    bottom: 0;
    top: 0;
    margin: 0;
  }
  </style>

You need to set postion:relative of outer DIV and position:absolute of inner div.
Try this. Here is the Demo

#one
{
    background-color: #EEE;
    margin: 62px 258px;
    padding: 5px;
    width: 200px;
    position: relative;   
}

#two
{
    background-color: #F00;
    display: inline-block;
    height: 30px;
    position: absolute;
    width: 100px;
    top:10px;
}?

This is all you need to read.

https://developer.mozilla.org/en-US/docs/Web/API/FileReader/readAsBinaryString

var height = 200;
var width  = 200;

canvas.width  = width;
canvas.height = height;

var ctx = canvas.getContext('2d');

ctx.strokeStyle = '#090';
ctx.beginPath();
ctx.arc(width/2, height/2, width/2 - width/10, 0, Math.PI*2);
ctx.stroke();

canvas.toBlob(function (blob) {
  //consider blob is your file object

  var reader = new FileReader();

  reader.onload = function () {
    console.log(reader.result);
  }

  reader.readAsBinaryString(blob);
});

If you need to handle error messages using jQuery.AJAX you will need to modify the xhr function so the responseType is not being modified when an error happens.

So you will have to modify the responseType to "blob" only if it is a successful call:

$.ajax({
    ...
    xhr: function() {
        var xhr = new XMLHttpRequest();
        xhr.onreadystatechange = function() {
            if (xhr.readyState == 2) {
                if (xhr.status == 200) {
                    xhr.responseType = "blob";
                } else {
                    xhr.responseType = "text";
                }
            }
        };
        return xhr;
    },
    ...
    error: function(xhr, textStatus, errorThrown) {
        // Here you are able now to access to the property "responseText"
        // as you have the type set to "text" instead of "blob".
        console.error(xhr.responseText);
    },
    success: function(data) {
        console.log(data); // Here is "blob" type
    }
});

Note

If you debug and place a breakpoint at the point right after setting the xhr.responseType to "blob" you can note that if you try to get the value for responseText you will get the following message:

The value is only accessible if the object's 'responseType' is '' or 'text' (was 'blob').

If you need all the PHP available parameters, use this:

function in_array(needle, haystack, argStrict) {
    var key = '', strict = !!argStrict;
    if (strict) {
        for (key in haystack) {
            if (haystack[key] === needle) {
                return true;
            }
        }
    }
    else {
        for (key in haystack) {
            if (haystack[key] == needle) {
                return true;
            }
        }
    }
    return false;
}

Replace '+' with '000'. For example, 'U+1F600' will become 'U0001F600' and prepend the Unicode code with "\" and print. Example:

>>> print("Learning : ", "\U0001F40D")
Learning :  
>>> 

Check this maybe it will help python unicode emoji

As well described in React's official docs, If you use routers that use the HTML5 pushState history API under the hood, you just need to below content to .htaccess file in public directory of your react-app.

Options -MultiViews
    RewriteEngine On
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^ index.html [QSA,L]

And if using relative path update the package.json like this:

"homepage": ".",

Note: If you are using react-router@^4, you can root <Link> using the basename prop on any <Router>.

import React from 'react';
import BrowserRouter as Router from 'react-router-dom';
...
<Router basename="/calendar"/>
<Link to="/today"/>

You need to set the timeout to "None" when you open the serial port:

ser = serial.Serial(**bco_port**, timeout=None, baudrate=115000, xonxoff=False, rtscts=False, dsrdtr=False) 

This is a blocking command, so you are waiting until you receive data that has newline (\n or \r\n) at the end: line = ser.readline()

Once you have the data, it will return ASAP.

If you have a Style component that you can require from your Component, then you could have something like this at the top of the file:

const Dimensions = require('Dimensions');

const window = Dimensions.get('window');

And then you could provide fulscreen: {width: window.width, height: window.height}, in your Style component. Hope this helps

This method zips a folder and adds all of the child files & folders (including empty folders) into the zip file.

void zipFolder(Path sourceDir, Path targetFile) throws IOException {
    ZipDirectoryVisitor zipVisitor = new ZipDirectoryVisitor(sourceDir);
    Files.walkFileTree(sourceDir, zipVisitor);
    FileOutputStream fos = new FileOutputStream(targetFile.toString());
    ZipOutputStream zos = new ZipOutputStream(fos);
    byte[] buffer = new byte[1024];
    for (ZipEntry entry : zipVisitor.getZipEntries()) {
        zos.putNextEntry(entry);
        Path curFile = Paths.get(sourceDir.getParent().toString(), entry.toString());
        if (!curFile.toFile().isDirectory()) {
            FileInputStream in = new FileInputStream(Paths.get(sourceDir.getParent().toString(), entry.toString()).toString());
            int len;
            while ((len = in.read(buffer)) > 0) {
                zos.write(buffer, 0, len);
            }
            in.close();
        }
        zos.closeEntry();
    }
    zos.close();

}

And here is the ZipDirectoryVisitor implementation:

class ZipDirectoryVisitor extends SimpleFileVisitor<Path> {
    private Path dirToZip;
    private List<ZipEntry> zipEntries; // files and folders inside source folder as zip entries
    public ZipDirectoryVisitor(Path dirToZip) throws IOException {
        this.dirToZip = dirToZip;
        zipEntries = new ArrayList<>();
    }

    @Override
    public FileVisitResult visitFile(Path path, BasicFileAttributes basicFileAttributes) throws IOException {
        // According to zip standard backslashes
        // should not be used in zip entries
        String zipFile = dirToZip.getParent().relativize(path).toString().replace("\\", "/");
        ZipEntry entry = new ZipEntry(zipFile);
        zipEntries.add(entry);
        return FileVisitResult.CONTINUE;
    }


    @Override
    public FileVisitResult preVisitDirectory(Path path, BasicFileAttributes basicFileAttributes) throws IOException {
        String zipDir = dirToZip.getParent().relativize(path).toString().replace("\\", "/");
        // Zip directory entries should end with a forward slash
        ZipEntry entry = new ZipEntry(zipDir + "/");
        zipEntries.add(entry);
        return FileVisitResult.CONTINUE;
    }


    @Override
    public FileVisitResult visitFileFailed(Path path, IOException e) throws IOException {
        System.err.format("Could not visit file %s while creating a file list from file tree", path);
        return FileVisitResult.TERMINATE;
    }

    public List<ZipEntry> getZipEntries() {
        return zipEntries;
    }
}

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

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

So, in your ES6 example with:

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

var a = new Animal();

module.exports = {Animal: Animal};

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

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

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

let a = new Animal();

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

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

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

module.exports = Animal;

And, then import it with:

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

let a = new Animal();

Thanks for Ripon Al Wasim's answer. I did some improvement. because of network problems, I retry three times until break loop.

driver.get(url)
# Get scroll height
last_height = driver.execute_script("return document.body.scrollHeight")
try_times = 0
while True:
    # Scroll down to bottom
    driver.execute_script("window.scrollBy(0,2000)")

    # Wait to load page
    time.sleep(scroll_delay)
    # Calculate new scroll height and compare with last scroll height
    new_height = driver.execute_script("return document.body.scrollHeight")

    if last_height == new_height:
        try_times += 1

    if try_times > 3:
        try_times = 0
        break
    last_height = new_height

OpenCV HSV range is: H: 0 to 179 S: 0 to 255 V: 0 to 255

On Gimp (or other photo manipulation sw) Hue range from 0 to 360, since opencv put color info in a single byte, the maximum number value in a single byte is 255 therefore openCV Hue values are equivalent to Hue values from gimp divided by 2.

I found when trying to do object detection based on HSV color space that a range of 5 (opencv range) was sufficient to filter out a specific color. I would advise you to use an HSV color palate to figure out the range that works best for your application.

More information will be useful.

When I was faced with the same error message all I had to do was to correctly configure the credentials page of the DataSource(I am using Report Builder 3). if you chose the default, the report would work fine in Report Builder but would fail on the Report Server.

Swift 3

The most upvoted answer is not correct for Swift 3.

The correct code to change color is:

self.navigationController?.navigationBar.tintColor = UIColor.white

If you want to change color, change UIColor.white above to the desired color

You should use stdClass if you want magic members, if you write a class - define what it contains.

I came up with a solution that allows you to use NSLocalizedString. I create a category of NSBundle call NSBundle+RunTimeLanguage. The interface is like this.

// NSBundle+RunTimeLanguage.h
#import <Foundation/Foundation.h>
@interface NSBundle (RunTimeLanguage)
#define NSLocalizedString(key, comment) [[NSBundle mainBundle] runTimeLocalizedStringForKey:(key) value:@"" table:nil]
- (NSString *)runTimeLocalizedStringForKey:(NSString *)key value:(NSString *)value table:(NSString *)tableName;
@end

The implementation is like this.

// NSBundle+RunTimeLanguage.m
#import "NSBundle+RunTimeLanguage.h"
#import "AppDelegate.h"

@implementation NSBundle (RunTimeLanguage)

- (NSString *)runTimeLocalizedStringForKey:(NSString *)key value:(NSString *)value table:(NSString *)tableName
{
    AppDelegate *appDelegate = (AppDelegate *)[UIApplication sharedApplication].delegate;
    NSString *path= [[NSBundle mainBundle] pathForResource:[appDelegate languageCode] ofType:@"lproj"];
    NSBundle *languageBundle = [NSBundle bundleWithPath:path];
    NSString *localizedString=[languageBundle localizedStringForKey:key value:key table:nil];
    return localizedString;
}
@end

Than just add import NSBundle+RunTimeLanguage.h into the files that use NSLocalizedString.

As you can see I store my languageCode in a property of AppDelegate. This could be stored anywhere you'd like.

This only thing I don't like about it is a Warning that NSLocalizedString marco redefined. Perhaps someone could help me fix this part.

You need to use reflection to get the method to start with, then "construct" it by supplying type arguments with MakeGenericMethod:

MethodInfo method = typeof(Sample).GetMethod(nameof(Sample.GenericMethod));
MethodInfo generic = method.MakeGenericMethod(myType);
generic.Invoke(this, null);

For a static method, pass null as the first argument to Invoke. That's nothing to do with generic methods - it's just normal reflection.

As noted, a lot of this is simpler as of C# 4 using dynamic - if you can use type inference, of course. It doesn't help in cases where type inference isn't available, such as the exact example in the question.

var pinIcon = new google.maps.MarkerImage(
    "http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=%E2%80%A2|00D900",
    null, /* size is determined at runtime */
    null, /* origin is 0,0 */
    null, /* anchor is bottom center of the scaled image */
    new google.maps.Size(12, 18)
);

 Try with the below codes. All should work. 
    $('select').val(2);
    $('select').prop('selectedIndex', 1);
    $('select>option[value="5"]').prop('selected', true);
    $('select>option:eq(3)').attr('selected', 'selected');
    $("select option:contains(COMMERCIAL)").attr('selected', true);

Another option is YADDRESS.

>>> import requests
>>> response = requests.get('https://website.com/id', headers={'Authorization': 'access_token myToken'})

If the above doesnt work , try this:

>>> import requests
>>> response = requests.get('https://api.buildkite.com/v2/organizations/orgName/pipelines/pipelineName/builds/1230', headers={ 'Authorization': 'Bearer <your_token>' })
>>> print response.json()

use some thing like

Form1 fc = Application.OpenForms["Form1 "] != null ? (Form1 ) Application.OpenForms["Form1 "] : null;

It will close the form1 you can open that form again if you want it using :

Form1 frm = New Form1();
frm.show();

There are many different versions of mail around. When you go beyond mail -s subject to1@address1 to2@address2

• With some mailx implementations, e.g. from mailutils on Ubuntu or Debian's bsd-mailx, it's easy, because there's an option for that.

  mailx -a 'Content-Type: text/html' -s "Subject" to@address <test.html
  

• With the Heirloom mailx, there's no convenient way. One possibility to insert arbitrary headers is to set editheaders=1 and use an external editor (which can be a script).

  ## Prepare a temporary script that will serve as an editor.
  
  ## This script will be passed to ed.
  temp_script=$(mktemp)
  cat <<'EOF' >>"$temp_script"
  1a
  Content-Type: text/html
  .
  $r test.html
  w
  q
  EOF
  ## Call mailx, and tell it to invoke the editor script
  EDITOR="ed -s $temp_script" heirloom-mailx -S editheaders=1 -s "Subject" to@address <<EOF
  ~e
  .
  EOF
  rm -f "$temp_script"
  

• With a general POSIX mailx, I don't know how to get at headers.

If you're going to use any mail or mailx, keep in mind that

• This isn't portable even within a given Linux distribution. For example, both Ubuntu and Debian have several alternatives for mail and mailx.

• When composing a message, mail and mailx treats lines beginning with ~ as commands. If you pipe text into mail, you need to arrange for this text not to contain lines beginning with ~.

If you're going to install software anyway, you might as well install something more predictable than mail/Mail/mailx. For example, mutt. With Mutt, you can supply most headers in the input with the -H option, but not Content-Type, which needs to be set via a mutt option.

mutt -e 'set content_type=text/html' -s 'hello' 'to@address' <test.html

Or you can invoke sendmail directly. There are several versions of sendmail out there, but they all support sendmail -t to send a mail in the simplest fashion, reading the list of recipients from the mail. (I think they don't all support Bcc:.) On most systems, sendmail isn't in the usual $PATH, it's in /usr/sbin or /usr/lib.

cat <<'EOF' - test.html | /usr/sbin/sendmail -t
To: to@address
Subject: hello
Content-Type: text/html

EOF

I use Composer-Setup.exe and it works fine. Just in case you need to know where is the composer.phar (to use with PhpStorm) :

C:\ProgramData\ComposerSetup\bin\composer.phar

The reason the size of your pointer is 4 bytes is because you are compiling for a 32-bit architecture. As FryGuy pointed out, on a 64-bit architecture you would see 8.

You can also use Object Oriented Programming (OOP) instead of procedural programming:

$fiveDays = new DateInterval('P5D');
$today = new DateTime();
$fiveDaysAgo = $today->sub(fiveDays); // or ->add(fiveDays); to add 5 days

Or with just one line of code:

$fiveDaysAgo = (new DateTime())->sub(new DateInterval('P5D'));

Coming a little later to the discussion but here a variation that's a little faster than the substring + array push one.

// substring + array push + end precalc
var chunks = [];

for (var i = 0, e = 3, charsLength = str.length; i < charsLength; i += 3, e += 3) {
    chunks.push(str.substring(i, e));
}

Pre-calculating the end value as part of the for loop is faster than doing the inline math inside substring. I've tested it in both Firefox and Chrome and they both show speedup.

You can try it here

I had trouble binding a value with any of the symbols in AngularJS 1.6. I did not get any value at all, only undefined, even though I did it the exact same way as other bindings in the same file that did work.

Problem was: my variable name had an underscore.

This fails:

bindings: { import_nr: '='}

This works:

bindings: { importnr: '='}

(Not completely related to the original question, but that was one of the top search results when I looked, so hopefully this helps someone with the same problem.)

Angular expressions do not support the ternary operator before 1.1.5, but it can be emulated like this:

condition && (answer if true) || (answer if false)

So in example, something like this would work:

<div ng-repeater="item in items">
    <div>{{item.description}}</div>
    <div>{{isExists(item) && 'available' || 'oh no, you don't have it'}}</div>
</div>

UPDATE: Angular 1.1.5 added support for ternary operators:

{{myVar === "two" ? "it's true" : "it's false"}}

these functions will solve the problem, you need to implement the DrawThumbnails function and have a global variable to store the images. I love to get this to work with a class object that has the ThumbnailImageArray as a member variable, but am struggling!

called as in addThumbnailImages(10);

var ThumbnailImageArray = [];

function addThumbnailImages(MaxNumberOfImages)
{
    var imgs = [];

        if (loadedimages==arr.length)
        {
            postaction(ThumbnailImageArray); //call postaction and pass in newimages array as parameter
        }
    };

    for (var i=0; i<arr.length; i++)
    {
        ThumbnailImageArray[i]=new Image();
        ThumbnailImageArray[i].src=arr[i];
        ThumbnailImageArray[i].onload=function(){ imageloadpost();};
        ThumbnailImageArray[i].onerror=function(){ imageloadpost();};
    }
    //return blank object with done() method    
    //remember user defined callback functions to be called when images load
    return  { done:function(f){ postaction=f || postaction } };
}

If you want a generic error you can setup all $.ajax() (which $.get() uses underneath) requests jQuery makes to display an error using $.ajaxSetup(), for example:

$.ajaxSetup({
  error: function(xhr, status, error) {
    alert("An AJAX error occured: " + status + "\nError: " + error);
  }
});

Just run this once before making any AJAX calls (no changes to your current code, just stick this before somewhere). This sets the error option to default to the handler/function above, if you made a full $.ajax() call and specified the error handler then what you had would override the above.

//you can do in this way...as BigDecimal is immutable so cant set values except in constructor

BigDecimal test = BigDecimal.ZERO;
BigDecimal result = test.add(new BigDecimal(30));
System.out.println(result);

result would be 30

Embed code example:

<object type="application/pdf" data="example.pdf" width="100%" height="100%" id="examplePDF" name="examplePDF"><param name='src' value='example.pdf'/></object>

<script>
   examplePDF.printWithDialog();
</script>

May have to fool around with the ids/names. Using adobe reader...

My experience with trying to use CSS to modify the scroll bars is don't. Only IE will let you do this.

With the module pygame.draw shapes like rectangles, circles, polygons, liens, ellipses or arcs can be drawn. Some examples:

pygame.draw.rect draws filled rectangular shapes or outlines. The arguments are the target Surface (i.s. the display), the color, the rectangle and the optional outline width. The rectangle argument is a tuple with the 4 components (x, y, width, height), where (x, y) is the upper left point of the rectangle. Alternatively, the argument can be a pygame.Rect object:

pygame.draw.rect(window, color, (x, y, width, height))

rectangle = pygame.Rect(x, y, width, height)
pygame.draw.rect(window, color, rectangle)

pygame.draw.circle draws filled circles or outlines. The arguments are the target Surface (i.s. the display), the color, the center, the radius and the optional outline width. The center argument is a tuple with the 2 components (x, y):

pygame.draw.circle(window, color, (x, y), radius)

pygame.draw.polygon draws filled polygons or contours. The arguments are the target Surface (i.s. the display), the color, a list of points and the optional contour width. Each point is a tuple with the 2 components (x, y):

pygame.draw.polygon(window, color, [(x1, y1), (x2, y2), (x3, y3)])

Minimal example:

import pygame

pygame.init()

window = pygame.display.set_mode((200, 200))
clock = pygame.time.Clock()

run = True
while run:
    clock.tick(60)
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False

    window.fill((255, 255, 255))

    pygame.draw.rect(window, (0, 0, 255), (20, 20, 160, 160))
    pygame.draw.circle(window, (255, 0, 0), (100, 100), 80)
    pygame.draw.polygon(window, (255, 255, 0), 
        [(100, 20), (100 + 0.8660 * 80, 140), (100 - 0.8660 * 80, 140)])

    pygame.display.flip()

pygame.quit()
exit()

Recent Update July 2017:

1. Go to Google Console
2. Click on Left most top panel and click credentials.
3. In the API keys table, you will find the API key in the key column.

Your module and your class AthleteList have the same name. The line

import AthleteList

imports the module and creates a name AthleteList in your current scope that points to the module object. If you want to access the actual class, use

AthleteList.AthleteList

In particular, in the line

return(AthleteList(templ.pop(0), templ.pop(0), templ))

you are actually accessing the module object and not the class. Try

return(AthleteList.AthleteList(templ.pop(0), templ.pop(0), templ))

You have forgotten to derive from Base

public class Ext : Base
                 ^^^^^^        

This should do it

replacements = {'zero':'0', 'temp':'bob', 'garbage':'nothing'}

with open('path/to/input/file') as infile, open('path/to/output/file', 'w') as outfile:
    for line in infile:
        for src, target in replacements.iteritems():
            line = line.replace(src, target)
        outfile.write(line)

EDIT: To address Eildosa's comment, if you wanted to do this without writing to another file, then you'll end up having to read your entire source file into memory:

lines = []
with open('path/to/input/file') as infile:
    for line in infile:
        for src, target in replacements.iteritems():
            line = line.replace(src, target)
        lines.append(line)
with open('path/to/input/file', 'w') as outfile:
    for line in lines:
        outfile.write(line)

Edit: If you are using Python 3.x, use replacements.items() instead of replacements.iteritems()

Math.floor(1+7/8)

This issue is fixed now with update Fabric Gradle version 1.30.0:

Update release: March 19, 2019

Please see this Link: https://docs.fabric.io/android/changelog.html#march-15-2019

Please update your classpath dependency in project level Gradle:

buildscript {
    // ... repositories, etc. ...

    dependencies {
        // ...other dependencies ...
        classpath 'io.fabric.tools:gradle:1.30.0'
    }
}

In Java as other suggest

listitem.setClickable(false);

Or in xml:

android:clickable="false"

It works very fine

audio /= np.max(np.abs(audio),axis=0)
image *= (255.0/image.max())

Using /= and *= allows you to eliminate an intermediate temporary array, thus saving some memory. Multiplication is less expensive than division, so

image *= 255.0/image.max()    # Uses 1 division and image.size multiplications

is marginally faster than

image /= image.max()/255.0    # Uses 1+image.size divisions

Since we are using basic numpy methods here, I think this is about as efficient a solution in numpy as can be.

In-place operations do not change the dtype of the container array. Since the desired normalized values are floats, the audio and image arrays need to have floating-point point dtype before the in-place operations are performed. If they are not already of floating-point dtype, you'll need to convert them using astype. For example,

image = image.astype('float64')

Since the SERVICE_USER table is not a pure join table, but has additional functional fields (blocked), you must map it as an entity, and decompose the many to many association between User and Service into two OneToMany associations : One User has many UserServices, and one Service has many UserServices.

You haven't shown us the most important part : the mapping and initialization of the relationships between your entities (i.e. the part you have problems with). So I'll show you how it should look like.

If you make the relationships bidirectional, you should thus have

class User {
    @OneToMany(mappedBy = "user")
    private Set<UserService> userServices = new HashSet<UserService>();
}

class UserService {
    @ManyToOne
    @JoinColumn(name = "user_id")
    private User user;

    @ManyToOne
    @JoinColumn(name = "service_code")
    private Service service;

    @Column(name = "blocked")
    private boolean blocked;
}

class Service {
    @OneToMany(mappedBy = "service")
    private Set<UserService> userServices = new HashSet<UserService>();
}

If you don't put any cascade on your relationships, then you must persist/save all the entities. Although only the owning side of the relationship (here, the UserService side) must be initialized, it's also a good practice to make sure both sides are in coherence.

User user = new User();
Service service = new Service();
UserService userService = new UserService();

user.addUserService(userService);
userService.setUser(user);

service.addUserService(userService);
userService.setService(service);

session.save(user);
session.save(service);
session.save(userService);

For Fedora:

# Fedora 18 or greater
sudo dnf group install "MinGW cross-compiler"

# Or (not recommended, because of its deprecation)
sudo yum groupinstall -y "MinGW cross-compiler"

If your icons are in an icon stack you can use the following code:

.icon-stack{ margin: auto; display: block; } 

I would suggest you have a look at BackgroundWorker. If you have a loop that large in your WinForm it will block and your app will look like it has hanged.

Look at BackgroundWorker.ReportProgress() to see how to report progress back to the UI thread.

For example:

private void Calculate(int i)
{
    double pow = Math.Pow(i, i);
}

private void button1_Click(object sender, EventArgs e)
{
    progressBar1.Maximum = 100;
    progressBar1.Step = 1;
    progressBar1.Value = 0;
    backgroundWorker.RunWorkerAsync();
}

private void backgroundWorker_DoWork(object sender, DoWorkEventArgs e)
{
    var backgroundWorker = sender as BackgroundWorker;
    for (int j = 0; j < 100000; j++)
    {
        Calculate(j);
        backgroundWorker.ReportProgress((j * 100) / 100000);
    }
}

private void backgroundWorker_ProgressChanged(object sender, ProgressChangedEventArgs e)
{
    progressBar1.Value = e.ProgressPercentage;
}

private void backgroundWorker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
    // TODO: do something with final calculation.
}

There are a million ways to do this.

The first one would be to go ahead and run the array through foreach anyway, assuming you do have an array.

In other cases this is what you might need:

foreach ((array) $items as $item) {
    print $item;
}

Note: to all the people complaining about typecast, please note that the OP asked cleanest way to skip a foreach if array is empty (emphasis is mine). A value of true, false, numbers or strings is not considered empty. In addition, this would work with objects implementing \Traversable, whereas is_array wouldn't work.

Simplest example would consist of:

1. Getting user input.

2. Composing XML SOAP message similar to this

   <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                  xmlns:xsd="http://www.w3.org/2001/XMLSchema"
                  xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
     <soap:Body>
       <GetInfoByZIP xmlns="http://www.webserviceX.NET">
         <USZip>string</USZip>
       </GetInfoByZIP>
     </soap:Body>
   </soap:Envelope>
   

3. POSTing message to webservice url using XHR

4. Parsing webservice's XML SOAP response similar to this

   <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
                  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                  xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <soap:Body>
     <GetInfoByZIPResponse xmlns="http://www.webserviceX.NET">
      <GetInfoByZIPResult>
       <NewDataSet xmlns="">
        <Table>
         <CITY>...</CITY>
         <STATE>...</STATE>
         <ZIP>...</ZIP>
         <AREA_CODE>...</AREA_CODE>
         <TIME_ZONE>...</TIME_ZONE>
        </Table>
       </NewDataSet>
      </GetInfoByZIPResult>
     </GetInfoByZIPResponse>
    </soap:Body>
   </soap:Envelope>
   

5. Presenting results to user.

But it's a lot of hassle without external JavaScript libraries.

So, that is why i do a two (or more) post.

I was having the same problem when starting the service (logs can not be opened).

I thought it was because i was trying to have htdocs inside a VeraCrypt encripted container, absurd since i hace such contained mounted and i use a juntion to not affect paths.

The i read the cause could be low ram: after some tests i get to the next conclusion.

Windows is not sending pages to virtual ram to free enough ram if it is a service, for applications it is doing it, i have more than 200GiB of pagefile ready to be used as virtual ram in a 4GiB 64 Bit windows 10.

My solution:

1. Run a free utility that free ram (512MiB in my test)
2. Inmediatly after start the service, it starts with no errors

Real Cause:

• I was using a virtual machine that uses 1/2 physical free ram (1.5GiB)

Hope this help others.

Enable NSZombieEnabled to know which object is being released and then accessed. Then check if the getResultSetFromDB: has anything to do with that. Also check if docids has anything inside and if it is being retained.

This way you can be sure there is nothing wrong.

The element that you posted looks like it's just copy-pasted from the Google Maps embed feature.

If you'd like to drop markers for the locations that you have, you'll need to write some JavaScript to do so. I'm learning how to do this as well.

Check out the following: https://developers.google.com/maps/documentation/javascript/overlays

It has several examples and code samples that can be easily re-used and adapted to fit your current problem.

I know the question is already answered, but I find that the existing answers are not valid:
they will return True for linked tables with a non working back-end.
Using DCount can be much slower, but is more reliable.

Function IsTable(sTblName As String) As Boolean
    'does table exists and work ?
    'note: finding the name in the TableDefs collection is not enough,
    '      since the backend might be invalid or missing

    On Error GoTo hell
    Dim x
    x = DCount("*", sTblName)
    IsTable = True
    Exit Function
hell:
    Debug.Print Now, sTblName, Err.Number, Err.Description
    IsTable = False

End Function

You can add a new property of type IFormFile to your view model

public class CreatePost
{
   public string ImageCaption { set;get; }
   public string ImageDescription { set;get; }
   public IFormFile MyImage { set; get; }
}

and in your GET action method, we will create an object of this view model and send to the view.

public IActionResult Create()
{
   return View(new CreatePost());
}

Now in your Create view which is strongly typed to our view model, have a form tag which has the enctype attribute set to "multipart/form-data"

@model CreatePost
<form asp-action="Create" enctype="multipart/form-data">   

    <input asp-for="ImageCaption"/>
    <input asp-for="ImageDescription"/>
    <input asp-for="MyImage"/>

    <input type="submit"/>
</form>

And your HttpPost action to handle the form posting

[HttpPost]
public IActionResult Create(CreatePost model)
{
   var img = model.MyImage;
   var imgCaption = model.ImageCaption;

   //Getting file meta data
   var fileName = Path.GetFileName(model.MyImage.FileName);
   var contentType = model.MyImage.ContentType;

   // do something with the above data
   // to do : return something
}

If you want to upload the file to some directory in your app, you should use IHostingEnvironment to get the webroot path. Here is a working sample.

public class HomeController : Controller
{
    private readonly IHostingEnvironment hostingEnvironment;
    public HomeController(IHostingEnvironment environment)
    {
        hostingEnvironment = environment;
    }
    [HttpPost]
    public IActionResult Create(CreatePost model)
    {
        // do other validations on your model as needed
        if (model.MyImage != null)
        {
            var uniqueFileName = GetUniqueFileName(model.MyImage.FileName);
            var uploads = Path.Combine(hostingEnvironment.WebRootPath, "uploads");
            var filePath = Path.Combine(uploads,uniqueFileName);
            model.MyImage.CopyTo(new FileStream(filePath, FileMode.Create)); 

            //to do : Save uniqueFileName  to your db table   
        }
        // to do  : Return something
        return RedirectToAction("Index","Home");
    }
    private string GetUniqueFileName(string fileName)
    {
        fileName = Path.GetFileName(fileName);
        return  Path.GetFileNameWithoutExtension(fileName)
                  + "_" 
                  + Guid.NewGuid().ToString().Substring(0, 4) 
                  + Path.GetExtension(fileName);
    }
}

This will save the file to uploads folder inside wwwwroot directory of your app with a random file name generated using Guids ( to prevent overwriting of files with same name)

Here we are using a very simple GetUniqueName method which will add 4 chars from a guid to the end of the file name to make it somewhat unique. You can update the method to make it more sophisticated as needed.

Should you be storing the full url to the uploaded image in the database ?

No. Do not store the full url to the image in the database. What if tomorrow your business decides to change your company/product name from www.thefacebook.com to www.facebook.com ? Now you have to fix all the urls in the table!

What should you store ?

You should store the unique filename which you generated above(the uniqueFileName varibale we used above) to store the file name. When you want to display the image back, you can use this value (the filename) and build the url to the image.

For example, you can do this in your view.

@{
    var imgFileName = "cats_46df.png";
}
<img src="~/uploads/@imgFileName"  alt="my img"/>

I just hardcoded an image name to imgFileName variable and used that. But you may read the stored file name from your database and set to your view model property and use that. Something like

<img src="~/uploads/@Model.FileName"  alt="my img"/>

Storing the image to table

If you want to save the file as bytearray/varbinary to your database, you may convert the IFormFile object to byte array like this

private byte[] GetByteArrayFromImage(IFormFile file)
{
    using (var target = new MemoryStream())
    {
        file.CopyTo(target);
        return target.ToArray();
    }
}

Now in your http post action method, you can call this method to generate the byte array from IFormFile and use that to save to your table. the below example is trying to save a Post entity object using entity framework.

[HttpPost]
public IActionResult Create(CreatePost model)
{
    //Create an object of your entity class and map property values
    var post=new Post() { ImageCaption = model.ImageCaption };

    if (model.MyImage != null)
    {
       post.Image =  GetByteArrayFromImage(model.MyImage);
    }
    _context.Posts.Add(post);
    _context.SaveChanges();
    return RedirectToAction("Index","Home");
}

Take a look on if your database is fine tuned. Especially the transactions isolation. Isn't good idea to increase the innodb_lock_wait_timeout variable.

Check your database transaction isolation level in the mysql cli:

mysql> SELECT @@GLOBAL.tx_isolation, @@tx_isolation, @@session.tx_isolation;
+-----------------------+-----------------+------------------------+
| @@GLOBAL.tx_isolation | @@tx_isolation  | @@session.tx_isolation |
+-----------------------+-----------------+------------------------+
| REPEATABLE-READ       | REPEATABLE-READ | REPEATABLE-READ        |
+-----------------------+-----------------+------------------------+
1 row in set (0.00 sec)

You could get improvements changing de isolation level, use the oracle like READ COMMITTED instead REPEATABLE READ (InnoDB Defaults)

mysql> SET tx_isolation = 'READ-COMMITTED';
Query OK, 0 rows affected (0.00 sec)

mysql> SET GLOBAL tx_isolation = 'READ-COMMITTED';
Query OK, 0 rows affected (0.00 sec)

mysql> 

Also try use SELECT FOR UPDATE only in if necesary.

This should do the trick

public static IEnumerable<T> FindVisualChildren<T>(DependencyObject depObj) where T : DependencyObject
{
    if (depObj != null)
    {
        for (int i = 0; i < VisualTreeHelper.GetChildrenCount(depObj); i++)
        {
            DependencyObject child = VisualTreeHelper.GetChild(depObj, i);
            if (child != null && child is T)
            {
                yield return (T)child;
            }

            foreach (T childOfChild in FindVisualChildren<T>(child))
            {
                yield return childOfChild;
            }
        }
    }
}

then you enumerate over the controls like so

foreach (TextBlock tb in FindVisualChildren<TextBlock>(window))
{
    // do something with tb here
}

To avoid nesting and ngSwitch, there is also this possibility, which leverages the way logical operators work in Javascript:

<ng-container *ngIf="foo === 1; then first; else (foo === 2 && second) || (foo === 3 && third)"></ng-container>
  <ng-template #first>First</ng-template>
  <ng-template #second>Second</ng-template>
  <ng-template #third>Third</ng-template>

VB.NET, nullables and the ternary operator:

Dim i As Integer? = If(True, Nothing, 5)

This took me some time to debug, since I expected i to contain Nothing.

What does i really contain? 0.

This is surprising but actually "correct" behavior: Nothing in VB.NET is not exactly the same as null in CLR: Nothing can either mean null or default(T) for a value type T, depending on the context. In the above case, If infers Integer as the common type of Nothing and 5, so, in this case, Nothing means 0.

The advantage of lists appears if you need to insert items in the middle and don't want to start resizing the array and shifting things around.

You're correct in that this is typically not the case. I've had a few very specific cases like that, but not too many.

Have you looked in to web deployment projects?

A good summary of LLVM is this:

At the frontend you have Perl, and many other high level languages. At the backend, you have the natives code that run directly on the machine.

At the centre is your intermediate code representation. If every high level language can be represented in this LLVM IR format, then analysis tools based on this IR can be easily reused - that is the basic rationale.

select * from table_name ORDER BY primary_id DESC FETCH FIRST 1 ROWS ONLY;

That's the simplest one without doing sub queries

function GetCellValues() {
    var table = document.getElementById('mytable');
    for (var r = 0, n = table.rows.length; r < n; r++) {
        for (var c = 0, m = table.rows[r].cells.length; c < m; c++) {
            alert(table.rows[r].cells[c].innerHTML);
        }
    }
}

Try this:

document.addEventListener("keydown", KeyCheck);  //or however you are calling your method
function KeyCheck(event)
{
   var KeyID = event.keyCode;
   switch(KeyID)
   {
      case 8:
      alert("backspace");
      break; 
      case 46:
      alert("delete");
      break;
      default:
      break;
   }
}

If your cases are likely to remain grouped in the future--if more than one case corresponds to one result--the switch may prove to be easier to read and maintain.

Why not encapsulate a set with a list, sort like:

new ArrayList( new LinkedHashSet() )

This leaves the other implementation for someone who is a real master of Collections ;-)

You could use the xpath :

//div[@class="measure-tab" and .//span[contains(., "someText")]]

Input :

<root>
<div class="measure-tab">
  <td> someText</td>
</div>
<div class="measure-tab">
  <div>
    <div2>
       <span>someText2</span>
   </div2>
  </div>
</div>
</root>

Output :

    Element='<div class="measure-tab">
  <div>
    <div2>
      <span>someText2</span>
    </div2>
  </div>
</div>'

try this:

patch -p1 < patchfile

As mentioned above, res.locals is a good (recommended) way to do this. See here for a quick tutorial on how to do this in Express.

I had similar problem when I tried to build a signed apk for my app.

Strange, it happened only when I wanted to build a release apk, while on debug apk everything worked OK.

Finally, looking on this thread, I checked for support library duplications in build.gradle and removed any duplications but this wasn't enough..

I had to do clean project and only then finally I've got it to work.

You should use built-in bootstrap4 spacing classes for customizing the spacing of elements, that's more convenient method .

@Sotirios Delimanolis answer do the job however I was looking for comparing strings within this mockMvc assertion

So here it is

.andExpect(content().string("\"Username already taken - please try with different username\""));

Of course my assertion fail:

java.lang.AssertionError: Response content expected:
<"Username already taken - please try with different username"> but was:<"Something gone wrong">

because:

  MockHttpServletResponse:
            Body = "Something gone wrong"

So this is proof that it works!

Protected internal best suites when you want a member or type to be used in a derived class from another assembly at the same time just want to consume the member or type in the parent assembly without deriving from the class where it is declared. Also if you want only to use a member or type with out deriving from another class, in the same assembly you can use internal only.

I found a simple solution, just open Settings of TortoiseSVN, and expand Icon Overlays, select Icon Set and change the icon set.

The default icon set of mine is XP Style, and I change it to Win10 because Win10 is the OS I am currently using.

Restart your computer and problem gets solved.

If you really want to use Deleted, you'd have to make your foreign keys nullable, but then you'd end up with orphaned records (which is one of the main reasons you shouldn't be doing that in the first place). So just use Remove()

ObjectContext.DeleteObject(entity) marks the entity as Deleted in the context. (It's EntityState is Deleted after that.) If you call SaveChanges afterwards EF sends a SQL DELETE statement to the database. If no referential constraints in the database are violated the entity will be deleted, otherwise an exception is thrown.

EntityCollection.Remove(childEntity) marks the relationship between parent and childEntity as Deleted. If the childEntity itself is deleted from the database and what exactly happens when you call SaveChanges depends on the kind of relationship between the two:

A thing worth noting is that setting .State = EntityState.Deleted does not trigger automatically detected change. (archive)

I tried this command to display the list of files in the directory.

dir /s /b > List.txt

In the file it displays the list below.

C:\Program Files (x86)\Cisco Systems\Cisco Jabber\XmppMgr.dll

C:\Program Files (x86)\Cisco Systems\Cisco Jabber\XmppSDK.dll

C:\Program Files (x86)\Cisco Systems\Cisco Jabber\accessories\Plantronics

C:\Program Files (x86)\Cisco Systems\Cisco Jabber\accessories\SennheiserJabberPlugin.dll

C:\Program Files (x86)\Cisco Systems\Cisco Jabber\accessories\Logitech\LogiUCPluginForCisco

C:\Program Files (x86)\Cisco Systems\Cisco Jabber\accessories\Logitech\LogiUCPluginForCisco\lucpcisco.dll

What is want to do is only to display sub-directory not the full directory path.

Just like this:

Cisco Jabber\XmppMgr.dll Cisco Jabber\XmppSDK.dll

Cisco Jabber\accessories\JabraJabberPlugin.dll

Cisco Jabber\accessories\Logitech

Cisco Jabber\accessories\Plantronics

Cisco Jabber\accessories\SennheiserJabberPlugin.dll

Not sure what kind of text box you are refering to. However, I'm not sure if you can do this in a text box on a user form.

A text box on a sheet you can though.

Sheets("Sheet1").Shapes("TextBox 1").TextFrame2.TextRange.Text = "R2=" & variable
Sheets("Sheet1").Shapes("TextBox 1").TextFrame2.TextRange.Characters(2, 1).Font.Superscript = msoTrue

And same thing for an excel cell

Sheets("Sheet1").Range("A1").Characters(2, 1).Font.Superscript = True

If this isn't what you're after you will need to provide more information in your question.

EDIT: posted this after the comment sorry

URLs can give a lot of clues, especially with Content Management Systems.

For example "http://abcxyz.com/node/46" looks a lot like Drupal.

Also many frameworks have standard JavaScript and CSS files they use.

Though weirdly named, you can use the getimagesize() function. This will also give you mime information:

Array
(
    [0] => 295 // width
    [1] => 295 // height
    [2] => 3 // http://php.net/manual/en/image.constants.php
    [3] => width="295" height="295" // width and height as attr's
    [bits] => 8
    [mime] => image/png
)

Return val from procedure

ALTER PROCEDURE testme @input  VARCHAR(10),
                       @output VARCHAR(20) output
AS
  BEGIN
      IF @input >= '1'
        BEGIN
            SET @output = 'i am back';

            RETURN;
        END
  END

DECLARE @get VARCHAR(20);

EXEC testme
  '1',
  @get output

SELECT @get 

Try this code.

public void send (String fileName) {
    String SFTPHOST = "host:IP";
    int SFTPPORT = 22;
    String SFTPUSER = "username";
    String SFTPPASS = "password";
    String SFTPWORKINGDIR = "file/to/transfer";

    Session session = null;
    Channel channel = null;
    ChannelSftp channelSftp = null;
    System.out.println("preparing the host information for sftp.");

    try {
        JSch jsch = new JSch();
        session = jsch.getSession(SFTPUSER, SFTPHOST, SFTPPORT);
        session.setPassword(SFTPPASS);
        java.util.Properties config = new java.util.Properties();
        config.put("StrictHostKeyChecking", "no");
        session.setConfig(config);
        session.connect();
        System.out.println("Host connected.");
        channel = session.openChannel("sftp");
        channel.connect();
        System.out.println("sftp channel opened and connected.");
        channelSftp = (ChannelSftp) channel;
        channelSftp.cd(SFTPWORKINGDIR);
        File f = new File(fileName);
        channelSftp.put(new FileInputStream(f), f.getName());
        log.info("File transfered successfully to host.");
    } catch (Exception ex) {
        System.out.println("Exception found while tranfer the response.");
    } finally {
        channelSftp.exit();
        System.out.println("sftp Channel exited.");
        channel.disconnect();
        System.out.println("Channel disconnected.");
        session.disconnect();
        System.out.println("Host Session disconnected.");
    }
}   

Take a look at the formats in ?strptime

R> foo <-  factor("1/15/2006 0:00:00")
R> foo <- as.Date(foo, format = "%m/%d/%Y %H:%M:%S")                                           
R> foo                                                                                       
 [1] "2006-01-15"                                                                             
R> class(foo)                                                                                
 [1] "Date"  

Note that this will work even if foo starts out as a character. It will also work if using other date formats (as.POSIXlt, as.POSIXct).

Even though there is something easy like .equals, I'd like to point out TWO mistakes you made in your code. The first: when you go through the arrays, you say b is true or false. Then you start again to check, because of the for-loop. But each time you are giving b a value. So, no matter what happens, the value b gets set to is always the value of the LAST for-loop. Next time, set boolean b = true, if equal = true, do nothing, if equal = false, b=false.

Secondly, you are now checking each value in array1 with each value in array2. If I understand correctly, you only need to check the values at the same location in the array, meaning you should have deleted the second for-loop and check like this: if (array2[i] == array1[i]). Then your code should function as well.

Your code would work like this:

public static void compareArrays(int[] array1, int[] array2) {
    boolean b = true;
    for (int i = 0; i < array2.length; i++) {
        if (array2[i] == array1[i]) {
            System.out.println("true");
        } else {
            b = false;
            System.out.println("False");
        }
    } 
    return b;

}

But as said by other, easier would be: Arrays.equals(ary1,ary2);

In case you arrive here looking for a way to make PDF from view templates in Express, a colleague and I made express-template-to-pdf

which allows you to generate PDF from whatever templates you're using in Express - Pug, Nunjucks, whatever.

It depends on html-pdf and is written to use in your routes just like you use res.render:

const pdfRenderer = require('@ministryofjustice/express-template-to-pdf')

app.set('views', path.join(__dirname, 'views'))
app.set('view engine', 'pug')

app.use(pdfRenderer())

If you've used res.render then using it should look obvious:

app.use('/pdf', (req, res) => {
    res.renderPDF('helloWorld', { message: 'Hello World!' });
})

You can pass options through to html-pdf to control the PDF document page size etc

Merely building on the excellent work of others.

You did not add # before id of the button. You do not have right selector in your jquery code. So jquery is never execute in your button click. its submitted your form directly not passing any ajax request.

See documentation: http://api.jquery.com/category/selectors/
its your friend.

Try this:

It seems that id: $("#Shareitem").val() is wrong if you want to pass the value of

<input type="hidden" name="id" value="" id="id">

you need to change this line:

id: $("#Shareitem").val()

by

id: $("#id").val()

All together:

 <script src="http://code.jquery.com/jquery-1.11.0.min.js"></script>
    <script>
    $(document).ready(function(){
      $("#Shareitem").click(function(e){
          e.preventDefault();
        $.ajax({type: "POST",
                url: "/imball-reagens/public/shareitem",
                data: { id: $("#Shareitem").val(), access_token: $("#access_token").val() },
                success:function(result){
          $("#sharelink").html(result);
        }});
      });
    });
    </script>

In 2020

check before use

You can use computedStyleMap()

The answer is valid but sometimes you need to check what unit it returns, you can get that without any slice() or substring() string.

var element = document.querySelector('.js-header-rep');
element.computedStyleMap().get('padding-left');

var element = document.querySelector('.jsCSS');_x000D_
var con = element.computedStyleMap().get('padding-left');_x000D_
console.log(con);

.jsCSS {_x000D_
  width: 10rem;_x000D_
  height: 10rem;_x000D_
  background-color: skyblue;_x000D_
  padding-left: 10px;_x000D_
}

<div class="jsCSS"></div>

I had trouble with the most popular answer (overthinking). It put AFolder in the \Server\MyFolder\AFolder and I wanted the contents of AFolder and below in MyFolder. This didn't work.

Copy-Item -Verbose -Path C:\MyFolder\AFolder -Destination \\Server\MyFolder -recurse -Force

Plus I needed to Filter and only copy *.config files.

This didn't work, with "\*" because it did not recurse

Copy-Item -Verbose -Path C:\MyFolder\AFolder\* -Filter *.config -Destination \\Server\MyFolder -recurse -Force

I ended up lopping off the beginning of the path string, to get the childPath relative to where I was recursing from. This works for the use-case in question and went down many subdirectories, which some other solutions do not.

Get-Childitem -Path "$($sourcePath)/**/*.config" -Recurse | 
ForEach-Object {
  $childPath = "$_".substring($sourcePath.length+1)
  $dest = "$($destPath)\$($childPath)" #this puts a \ between dest and child path
  Copy-Item -Verbose -Path $_ -Destination $dest -Force   
}

The answer shared by @mockinterface is correct. Although I would like to add my 2 cents to it.

If someone is using frameworks like scrapy the you will have to use /html/body//a[contains(@href,'com')][2]/@href along with get() like this:

response.xpath('//a[contains(@href,'com')][2]/@href').get()

jus do this import { shallow, mount } from "enzyme";

const store = mockStore({
  startup: { complete: false }
});

describe("==== Testing App ======", () => {
  const setUpFn = props => {
    return mount(
      <Provider store={store}>
        <App />
      </Provider>
    );
  };

  let wrapper;
  beforeEach(() => {
    wrapper = setUpFn();
  });

I had faced same issue whenever I tried executing curl on my https server.

About to connect() to localhost port 443 (#0)
Trying ::1...
Connected to localhost (::1) port 443 (#0)
Initializing NSS with certpath: sql:/etc/pki/nssdb

Observed this issue when I configured keystore path incorrectly. After correcting keystore path it worked.

either of these jQuery functions should work:

$("#element").removeAttr("style");
$("#element").removeAttr("background-color") 

I recognize that the answer works and has been accepted but there is a much cleaner way to write that query. Tested on mysql and postgres.

SELECT wpoi.order_id As No_Commande
FROM  wp_woocommerce_order_items AS wpoi
LEFT JOIN wp_postmeta AS wpp ON wpoi.order_id = wpp.post_id 
                            AND wpp.meta_key = '_shipping_first_name'
WHERE  wpoi.order_id =2198 

It is just a typo(I guess)-

p+=1;

instead of p +1=p; is required .

As name suggest lvalue expression should be left-hand operand of the assignment operator.

Answer

You can't according to the PHP manual:

Once the cookies have been set, they can be accessed on the next page load with the $_COOKIE or $HTTP_COOKIE_VARS arrays.

This is because cookies are sent in response headers to the browser and the browser must then send them back with the next request. This is why they are only available on the second page load.

Work around

But you can work around it by also setting $_COOKIE when you call setcookie():

if(!isset($_COOKIE['lg'])) {
    setcookie('lg', 'ro');
    $_COOKIE['lg'] = 'ro';
}
echo $_COOKIE['lg'];

The simplest way is using libraries like google-http-java-client but if you want parse the JSON response by yourself you can do that in a multiple ways, you can use org.json, json-simple, Gson, minimal-json, jackson-mapper-asl (from 1.x)... etc

A set of simple examples:

Using Gson:

import java.io.IOException;

import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;

public class Gson {

    public static void main(String[] args) {
    }

    public HttpResponse http(String url, String body) {

        try (CloseableHttpClient httpClient = HttpClientBuilder.create().build()) {
            HttpPost request = new HttpPost(url);
            StringEntity params = new StringEntity(body);
            request.addHeader("content-type", "application/json");
            request.setEntity(params);
            HttpResponse result = httpClient.execute(request);
            String json = EntityUtils.toString(result.getEntity(), "UTF-8");

            com.google.gson.Gson gson = new com.google.gson.Gson();
            Response respuesta = gson.fromJson(json, Response.class);

            System.out.println(respuesta.getExample());
            System.out.println(respuesta.getFr());

        } catch (IOException ex) {
        }
        return null;
    }

    public class Response{

        private String example;
        private String fr;

        public String getExample() {
            return example;
        }
        public void setExample(String example) {
            this.example = example;
        }
        public String getFr() {
            return fr;
        }
        public void setFr(String fr) {
            this.fr = fr;
        }
    }
}

Using json-simple:

import java.io.IOException;

import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;
import org.json.simple.JSONArray;
import org.json.simple.JSONObject;
import org.json.simple.parser.JSONParser;

public class JsonSimple {

    public static void main(String[] args) {

    }

    public HttpResponse http(String url, String body) {

        try (CloseableHttpClient httpClient = HttpClientBuilder.create().build()) {
            HttpPost request = new HttpPost(url);
            StringEntity params = new StringEntity(body);
            request.addHeader("content-type", "application/json");
            request.setEntity(params);
            HttpResponse result = httpClient.execute(request);

            String json = EntityUtils.toString(result.getEntity(), "UTF-8");
            try {
                JSONParser parser = new JSONParser();
                Object resultObject = parser.parse(json);

                if (resultObject instanceof JSONArray) {
                    JSONArray array=(JSONArray)resultObject;
                    for (Object object : array) {
                        JSONObject obj =(JSONObject)object;
                        System.out.println(obj.get("example"));
                        System.out.println(obj.get("fr"));
                    }

                }else if (resultObject instanceof JSONObject) {
                    JSONObject obj =(JSONObject)resultObject;
                    System.out.println(obj.get("example"));
                    System.out.println(obj.get("fr"));
                }

            } catch (Exception e) {
                // TODO: handle exception
            }

        } catch (IOException ex) {
        }
        return null;
    }
}

etc...

From your output:

no listening sockets available, shutting down

what basically means, that any port in which one apache is going to be listening is already being used by another application.

netstat -punta | grep LISTEN

Will give you a list of all the ports being used and the information needed to recognize which process is so you can kill stop or do whatever you want to do with it.

After doing a nmap of your ip I can see that

80/tcp    open     http

so I guess you sorted it out.

unique only removes consecutive duplicate elements (which is necessary for it to run in linear time), so you should perform the sort first. It will remain sorted after the call to unique.

This code explains the use of the ~tilda character, which was the most confusing thing to me. Once I understood this, it makes things much easier to understand:

@ECHO off
SET "PATH=%~dp0;%PATH%"
ECHO %PATH%
ECHO.
CALL :testargs "these are days" "when the brave endure"
GOTO :pauseit
:testargs
SET ARGS=%~1;%~2;%1;%2
ECHO %ARGS%
ECHO.
exit /B 0
:pauseit
pause

You can just set the onClick of an ImageView and also set it to be clickable, Or set the drawableBottom property of a regular button.

    ImageView iv = (ImageView)findViewById(R.id.ImageView01);
   iv.setOnClickListener(new OnClickListener() {
   public void onClick(View v) {
    // TODO Auto-generated method stub

   }
   });

I had the same problem and I searched a lot in web but no solution worked for me .finally I noticed by chance that mysql is using port 3308 instead of port 3306 which seems to be default ,,, I changed the port to 3306 and surprisingly it worked :) .... (my problem was in connecting php to mysql database, php my admin page was shown perfectly)

The approach you're looking for is FillDown. Another way so you don't have to kick your head off every time is to store formulas in an array of strings. Combining them gives you a powerful method of inputting formulas by the multitude. Code follows:

Sub FillDown()

    Dim strFormulas(1 To 3) As Variant

    With ThisWorkbook.Sheets("Sheet1")
        strFormulas(1) = "=SUM(A2:B2)"
        strFormulas(2) = "=PRODUCT(A2:B2)"
        strFormulas(3) = "=A2/B2"

        .Range("C2:E2").Formula = strFormulas
        .Range("C2:E11").FillDown
    End With

End Sub

Screenshots:

Result as of line: .Range("C2:E2").Formula = strFormulas:

Result as of line: .Range("C2:E11").FillDown:

Of course, you can make it dynamic by storing the last row into a variable and turning it to something like .Range("C2:E" & LRow).FillDown, much like what you did.

Hope this helps!

Note also that if you have wordpress just scroll down to the bottom of the webpage when in edit mode, and select "featured image" (bottom right side of screen).

After spending much time searching for a response to this answer: how to download a simple image from my API restful server written in Node.js into an Angular component app, I finally found a beautiful answer in this web Angular HttpClient Blob. Essentially it consist on:

API Node.js restful:

   /* After routing the path you want ..*/
  public getImage( req: Request, res: Response) {

    // Check if file exist...
    if (!req.params.file) {
      return res.status(httpStatus.badRequest).json({
        ok: false,
        msg: 'File param not found.'
      })
    }
    const absfile = path.join(STORE_ROOT_DIR,IMAGES_DIR, req.params.file);

    if (!fs.existsSync(absfile)) {
      return res.status(httpStatus.badRequest).json({
        ok: false,
        msg: 'File name not found on server.'
      })
    }
    res.sendFile(path.resolve(absfile));
  }

Angular 6 tested component service (EmployeeService on my case):

  downloadPhoto( name: string) : Observable<Blob> {
    const url = environment.api_url + '/storer/employee/image/' + name;

    return this.http.get(url, { responseType: 'blob' })
      .pipe(
        takeWhile( () => this.alive),
        filter ( image => !!image));
  }

Template

 <img [src]="" class="custom-photo" #photo>

Component subscriber and use:

@ViewChild('photo') image: ElementRef;

I've added a number of helper methods to the O2 Platform (Open Source project) which allow you easily script an interaction with another process via the console output and input (see http://code.google.com/p/o2platform/source/browse/trunk/O2_Scripts/APIs/Windows/CmdExe/CmdExeAPI.cs)

Also useful for you might be the API that allows the viewing of the console output of the current process (in an existing control or popup window). See this blog post for more details: http://o2platform.wordpress.com/2011/11/26/api_consoleout-cs-inprocess-capture-of-the-console-output/ (this blog also contains details of how to consume the console output of new processes)

In an upvoted comment to the accepted answer, Joe asks:

Is there any way to print to the console AND capture the output so that it shows in the junit report?

In UNIX, this is commonly referred to as teeing. Ideally, teeing rather than capturing would be the py.test default. Non-ideally, neither py.test nor any existing third-party py.test plugin (...that I know of, anyway) supports teeing – despite Python trivially supporting teeing out-of-the-box.

Monkey-patching py.test to do anything unsupported is non-trivial. Why? Because:

• Most py.test functionality is locked behind a private _pytest package not intended to be externally imported. Attempting to do so without knowing what you're doing typically results in the public pytest package raising obscure exceptions at runtime. ^{Thanks alot, py.test. Really robust architecture you got there.}
• Even when you do figure out how to monkey-patch the private _pytest API in a safe manner, you have to do so before running the public pytest package run by the external py.test command. You cannot do this in a plugin (e.g., a top-level conftest module in your test suite). By the time py.test lazily gets around to dynamically importing your plugin, any py.test class you wanted to monkey-patch has long since been instantiated – and you do not have access to that instance. This implies that, if you want your monkey-patch to be meaningfully applied, you can no longer safely run the external py.test command. Instead, you have to wrap the running of that command with a custom setuptools test command that (in order):
  1. Monkey-patches the private _pytest API.
  2. Calls the public pytest.main() function to run the py.test command.

This answer monkey-patches py.test's -s and --capture=no options to capture stderr but not stdout. By default, these options capture neither stderr nor stdout. This isn't quite teeing, of course. But every great journey begins with a tedious prequel everyone forgets in five years.

Why do this? I shall now tell you. My py.test-driven test suite contains slow functional tests. Displaying the stdout of these tests is helpful and reassuring, preventing leycec from reaching for killall -9 py.test when yet another long-running functional test fails to do anything for weeks on end. Displaying the stderr of these tests, however, prevents py.test from reporting exception tracebacks on test failures. Which is completely unhelpful. Hence, we coerce py.test to capture stderr but not stdout.

Before we get to it, this answer assumes you already have a custom setuptools test command invoking py.test. If you don't, see the Manual Integration subsection of py.test's well-written Good Practices page.

Do not install pytest-runner, a third-party setuptools plugin providing a custom setuptools test command also invoking py.test. If pytest-runner is already installed, you'll probably need to uninstall that pip3 package and then adopt the manual approach linked to above.

Assuming you followed the instructions in Manual Integration highlighted above, your codebase should now contain a PyTest.run_tests() method. Modify this method to resemble:

class PyTest(TestCommand):
             .
             .
             .
    def run_tests(self):
        # Import the public "pytest" package *BEFORE* the private "_pytest"
        # package. While importation order is typically ignorable, imports can
        # technically have side effects. Tragicomically, that is the case here.
        # Importing the public "pytest" package establishes runtime
        # configuration required by submodules of the private "_pytest" package.
        # The former *MUST* always be imported before the latter. Failing to do
        # so raises obtuse exceptions at runtime... which is bad.
        import pytest
        from _pytest.capture import CaptureManager, FDCapture, MultiCapture

        # If the private method to be monkey-patched no longer exists, py.test
        # is either broken or unsupported. In either case, raise an exception.
        if not hasattr(CaptureManager, '_getcapture'):
            from distutils.errors import DistutilsClassError
            raise DistutilsClassError(
                'Class "pytest.capture.CaptureManager" method _getcapture() '
                'not found. The current version of py.test is either '
                'broken (unlikely) or unsupported (likely).'
            )

        # Old method to be monkey-patched.
        _getcapture_old = CaptureManager._getcapture

        # New method applying this monkey-patch. Note the use of:
        #
        # * "out=False", *NOT* capturing stdout.
        # * "err=True", capturing stderr.
        def _getcapture_new(self, method):
            if method == "no":
                return MultiCapture(
                    out=False, err=True, in_=False, Capture=FDCapture)
            else:
                return _getcapture_old(self, method)

        # Replace the old with the new method.
        CaptureManager._getcapture = _getcapture_new

        # Run py.test with all passed arguments.
        errno = pytest.main(self.pytest_args)
        sys.exit(errno)

To enable this monkey-patch, run py.test as follows:

python setup.py test -a "-s"

Stderr but not stdout will now be captured. Nifty!

Extending the above monkey-patch to tee stdout and stderr is left as an exercise to the reader with a barrel-full of free time.

For Android studio v2.1

Follow these easy steps from images.

1. Go "File" and click "Project structure".

2. Then select "Project" from left menu and then change "Gradle version" to the version your sdk manager has installed. In my case it is 2.10 so i change version to 2.10 and then click on "Ok". And then android studio automatically do gradle sync again and error was fixed.

There's another way with post instead of ajax

var jqxhr = $.post( "example.php", function() {
  alert( "success" );
})
  .done(function() {
    alert( "second success" );
  })
  .fail(function() {
    alert( "error" );
  })
  .always(function() {
    alert( "finished" );
  });

I've tried ControlBrushKey but it didn't work for unselected rows. The background for the unselected row was still white. But I've managed to find out that I have to override the rowstyle.

<DataGrid x:Name="pbSelectionDataGrid" Height="201" Margin="10,0"
          FontSize="20" SelectionMode="Single" FontWeight="Bold">
    <DataGrid.Resources>
        <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="#FFFDD47C"/>
        <SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="#FFA6E09C"/>
        <SolidColorBrush x:Key="{x:Static SystemColors.HighlightTextBrushKey}" Color="Red"/>
        <SolidColorBrush x:Key="{x:Static SystemColors.ControlTextBrushKey}" Color="Violet"/>
    </DataGrid.Resources>
    <DataGrid.RowStyle>
        <Style TargetType="DataGridRow">
            <Setter Property="Background" Value="LightBlue" />
        </Style>
    </DataGrid.RowStyle>
</DataGrid>

I know this is an older thread but I wanted to give what I think to be helpful information.

I personally use PyPy which is really easy to install using pip. I interchangeably use Python/PyPy interpreter, you don't need to change your code at all and I've found it to be roughly 40x faster than the standard python interpreter (Either Python 2x or 3x). I use pyCharm Community Edition to manage my code and I love it.

I like writing code in python as I think it lets you focus more on the task than the language, which is a huge plus for me. And if you need it to be even faster, you can always compile to a binary for Windows, Linux, or Mac (not straight forward but possible with other tools). From my experience, I get about 3.5x speedup over PyPy when compiling, meaning 140x faster than python. PyPy is available for Python 3x and 2x code and again if you use an IDE like PyCharm you can interchange between say PyPy, Cython, and Python very easily (takes a little of initial learning and setup though).

Some people may argue with me on this one, but I find PyPy to be faster than Cython. But they're both great choices though.

Edit: I'd like to make another quick note about compiling: when you compile, the resulting binary is much bigger than your python script as it builds all dependencies into it, etc. But then you get a few distinct benefits: speed!, now the app will work on any machine (depending on which OS you compiled for, if not all. lol) without Python or libraries, it also obfuscates your code and is technically 'production' ready (to a degree). Some compilers also generate C code, which I haven't really looked at or seen if it's useful or just gibberish. Good luck.

Hope that helps.

Bootstrap 4 (update 2019)

A multi-item carousel can be accomplished in several ways as explained here. Another option is to use separate thumbnails to navigate the carousel slides.

Bootstrap 3 (original answer)

This can be done using the grid inside each carousel item.

       <div id="myCarousel" class="carousel slide">
                <div class="carousel-inner">
                    <div class="item active">
                        <div class="row">
                            <div class="col-sm-3">..
                            </div>
                            <div class="col-sm-3">..
                            </div>
                            <div class="col-sm-3">..
                            </div>
                            <div class="col-sm-3">..
                            </div>
                        </div>
                        <!--/row-->
                    </div>
                    ...add more item(s)
                 </div>
        </div>

I faced the same 415 http error when sending objects, serialized into JSON, via PUT/PUSH requests to my JAX-rs services, in other words my server was not able to de-serialize the objects from JSON. In my case, the server was able to serialize successfully the same objects in JSON when sending them into its responses.

As mentioned in the other responses I have correctly set the Accept and Content-Type headers to application/json, but it doesn't suffice.

Solution

I simply forgot a default constructor with no parameters for my DTO objects. Yes this is the same reasoning behind @Entity objects, you need a constructor with no parameters for the ORM to instantiate objects and populate the fields later.

Adding the constructor with no parameters to my DTO objects solved my issue. Here follows an example that resembles my code:

Wrong

@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
public class NumberDTO {
    public NumberDTO(Number number) {
        this.number = number;
    }

    private Number number;

    public Number getNumber() {
        return number;
    }

    public void setNumber(Number string) {
        this.number = string;
    }
}

Right

@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
public class NumberDTO {

    public NumberDTO() {
    }

    public NumberDTO(Number number) {
        this.number = number;
    }

    private Number number;

    public Number getNumber() {
        return number;
    }

    public void setNumber(Number string) {
        this.number = string;
    }
}

I lost hours, I hope this'll save yours ;-)

Add following to get best warnings, you will not regret it. If you can, compile WISE (warning is error)

- Wall -pedantic -Weffc++ -Werror

This is similar to, but more general than, @Jacob Relkin's solution:

This is ES2015:

const randomChoice = arr => {
    const randIndex = Math.floor(Math.random() * arr.length);
    return arr[randIndex];
};

The code works by selecting a random number between 0 and the length of the array, then returning the item at that index.

From Oracle's java tutorial

import java.net.*;
import java.io.*;

public class URLConnectionReader {
    public static void main(String[] args) throws Exception {
        URL yahoo = new URL("http://www.yahoo.com/");
        URLConnection yc = yahoo.openConnection();
        BufferedReader in = new BufferedReader(
                                new InputStreamReader(
                                yc.getInputStream()));
        String inputLine;

        while ((inputLine = in.readLine()) != null) 
            System.out.println(inputLine);
        in.close();
    }
}

The reason you're facing this is due to the difference between composition and aggregation.

In composition, the child object is created when the parent is created and is destroyed when its parent is destroyed. So its lifetime is controlled by its parent. e.g. A blog post and its comments. If a post is deleted, its comments should be deleted. It doesn't make sense to have comments for a post that doesn't exist. Same for orders and order items.

In aggregation, the child object can exist irrespective of its parent. If the parent is destroyed, the child object can still exist, as it may be added to a different parent later. e.g.: the relationship between a playlist and the songs in that playlist. If the playlist is deleted, the songs shouldn't be deleted. They may be added to a different playlist.

The way Entity Framework differentiates aggregation and composition relationships is as follows:

• For composition: it expects the child object to a have a composite primary key (ParentID, ChildID). This is by design as the IDs of the children should be within the scope of their parents.

• For aggregation: it expects the foreign key property in the child object to be nullable.

So, the reason you're having this issue is because of how you've set your primary key in your child table. It should be composite, but it's not. So, Entity Framework sees this association as aggregation, which means, when you remove or clear the child objects, it's not going to delete the child records. It'll simply remove the association and sets the corresponding foreign key column to NULL (so those child records can later be associated with a different parent). Since your column does not allow NULL, you get the exception you mentioned.

Solutions:

1- If you have a strong reason for not wanting to use a composite key, you need to delete the child objects explicitly. And this can be done simpler than the solutions suggested earlier:

context.Children.RemoveRange(parent.Children);

2- Otherwise, by setting the proper primary key on your child table, your code will look more meaningful:

parent.Children.Clear();

'[{"event":"inbound","ts":1426249238}]' is a string, you cannot access any properties there. You will have to parse it to an object, with JSON.parse() and then handle it like a normal object

You need to make your anchor display: block or display: inline-block; and then it will accept the width and height values.

If you have a PC with internet access in your LAN, you should install a local Maven repository.

I recommend Artifactory Open Source. This is what we use in our organization, it is really easy to setup.

Artifactory acts as a proxy between your build tool (Maven, Ant, Ivy, Gradle etc.) and the outside world.

It caches remote artifacts so that you don’t have to download them over and over again.

It blocks unwanted (and sometimes security-sensitive) external requests for internal artifacts and controls how and where artifacts are deployed, and by whom.

After setting up Artifactory you just need to change Maven's settings.xml in the development machines:

<?xml version="1.0" encoding="UTF-8"?>
<settings xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd" xmlns="http://maven.apache.org/SETTINGS/1.0.0"

We used this solution because we had problems with internet access in our development machines and some artifacts downloaded corrupted files or didn't download at all. We haven't had problems since.

System.in.read() reads from the standard input.

The standard input can be used to get input from user in a console environment but, as such user interface has no editing facilities, the interactive use of standard input is restricted to courses that teach programming.

Most production use of standard input is in programs designed to work inside Unix command-line pipelines. In such programs the payload that the program is processing is coming from the standard input and the program's result gets written to the standard output. In that case the standard input is never written directly by the user, it is the redirected output of another program or the contents of a file.

A typical pipeline looks like this:

# list files and directories ordered by increasing size
du -s * | sort -n

sort reads its data from the standard input, which is in fact the output of the du command. The sorted data is written to the standard output of sort, which ends up on the console by default, and can be easily redirected to a file or to another command.

As such, the standard input is comparatively rarely used in Java.

You can do something like this below:

//when the Add Field button is clicked
$("#add").click(function (e) {
//Append a new row of code to the "#items" div
  $("#items").append('<div><input type="text" name="input[]"><button  class="delete">Delete</button></div>');
});

You could overlay one element above the blurred element like so

DEMO

div {
    position: absolute;
    left:0;
    top: 0;
}
p {
    position: absolute;
    left:0;
    top: 0;
}

setval('sequence_name', sequence_value)

In Simple Words -

The export statement is used when creating JavaScript modules to export functions, objects, or primitive values from the module so they can be used by other programs with the import statement.

Here is a link to get clear understanding : MDN Web Docs

Verified the following on Virtualbox-5.0.24, Android_x86-4.4-r5. You get a screen similar to an 8" table. You can play around with the xxx in DPI=xxx, to change the resolution. xxx=100 makes it really small to match a real table exactly, but it may be too small when working with android in Virtualbox.

VBoxManage setextradata <VmName> "CustomVideoMode1" "440x680x16"

First, I would like to clarify something. Is this a post back (trip back to server) never occur, or is it the post back occurs, but it never gets into the ddlCountry_SelectedIndexChanged event handler?

I am not sure which case you are having, but if it is the second case, I can offer some suggestion. If it is the first case, then the following is FYI.

For the second case (event handler never fires even though request made), you may want to try the following suggestions:

1. Query the Request.Params[ddlCountries.UniqueID] and see if it has value. If it has, manually fire the event handler.
2. As long as view state is on, only bind the list data when it is not a post back.
3. If view state has to be off, then put the list data bind in OnInit instead of OnLoad.

Beware that when calling Control.DataBind(), view state and post back information would no longer be available from the control. In the case of view state is on, between post back, values of the DropDownList would be kept intact (the list does not to be rebound). If you issue another DataBind in OnLoad, it would clear out its view state data, and the SelectedIndexChanged event would never be fired.

In the case of view state is turned off, you have no choice but to rebind the list every time. When a post back occurs, there are internal ASP.NET calls to populate the value from Request.Params to the appropriate controls, and I suspect happen at the time between OnInit and OnLoad. In this case, restoring the list values in OnInit will enable the system to fire events correctly.

Thanks for your time reading this, and welcome everyone to correct if I am wrong.

The Bitmap class is an implementation of the Image class. The Image class is an abstract class;

The Bitmap class contains 12 constructors that construct the Bitmap object from different parameters. It can construct the Bitmap from another bitmap, and the string address of the image.

See more in this comprehensive sample.

Two generic ways to do the same thing... I'm not aware of any specific open solutions to do this, but it'd be rather trivial to do.

You could write a daily or weekly cron/jenkins job to scrape the previous time period's email from the archive looking for your keyworkds/combinations. Sending a batch digest with what it finds, if anything.

But personally, I'd Setup a specific email account to subscribe to the various security lists you're interested in. Add a simple automated script to parse the new emails for various keywords or combinations of keywords, when it finds a match forward that email on to you/your team. Just be sure to keep the keywords list updated with new products you're using.

You could even do this with a gmail account and custom rules, which is what I currently do, but I have setup an internal inbox in the past with a simple python script to forward emails that were of interest.

You can't. You can only have one slide size and one orientation per presentation.

Are you projecting the presentation or delivering it on a laptop? If so, the size is sort of irrelevant.
Regardless of the slide size, the projected/displayed image will never be longer or wider than the projector/display accepts.

This may also happen if your JSON file is not just 1 JSON record. A JSON record looks like this:

[{"some data": value, "next key": "another value"}]

It opens and closes with a bracket [ ], within the brackets are the braces { }. There can be many pairs of braces, but it all ends with a close bracket ]. If your json file contains more than one of those:

[{"some data": value, "next key": "another value"}]
[{"2nd record data": value, "2nd record key": "another value"}]

then loads() will fail.

I verified this with my own file that was failing.

import json

guestFile = open("1_guests.json",'r')
guestData = guestFile.read()
guestFile.close()
gdfJson = json.loads(guestData)

This works because 1_guests.json has one record []. The original file I was using all_guests.json had 6 records separated by newline. I deleted 5 records, (which I already checked to be bookended by brackets) and saved the file under a new name. Then the loads statement worked.

Error was

   raise ValueError(errmsg("Extra data", s, end, len(s)))
ValueError: Extra data: line 2 column 1 - line 10 column 1 (char 261900 - 6964758)

PS. I use the word record, but that's not the official name. Also, if your file has newline characters like mine, you can loop through it to loads() one record at a time into a json variable.

Here's the answer

Steps to follow:

1. Open the Visual Basic Editor. In Excel, hit Alt+F11 if on Windows, Fn+Option+F11 if on a Mac.

2. Insert a new module. From the menu: Insert -> Module (Don't skip this!).

3. Create a Public function. Example:

   Public Function findArea(ByVal width as Double, _
                            ByVal height as Double) As Double
       ' Return the area
       findArea = width * height
   End Function
   

4. Then use it in any cell like you would any other function: =findArea(B12,C12).

If you're looking for "in-place" editing of a ListView's contents (specifically the subitems of a ListView in details view mode), you'll need to implement this yourself, or use a third-party control.

By default, the best you can achieve with a "standard" ListView is to set it's LabelEdit property to true to allow the user to edit the text of the first column of the ListView (assuming you want to allow a free-format text edit).

Some examples (including full source-code) of customized ListView's that allow "in-place" editing of sub-items are:

C# Editable ListView
In-place editing of ListView subitems

I've found the answer regarding how to do this myself. Inside the model code, just put:

For Rails <= 2:

include ActionController::UrlWriter

For Rails 3:

include Rails.application.routes.url_helpers

This magically makes thing_path(self) return the URL for the current thing, or other_model_path(self.association_to_other_model) return some other URL.

Lots of good answers, but here is one more ;)

You can add handler for the click to the table

<table id = 'dsTable' onclick="tableclick(event)">

And then just find out what the target of the event was

function tableclick(e) {
    if(!e)
     e = window.event;

    if(e.target.value == "Delete")
       deleteRow( e.target.parentNode.parentNode.rowIndex );
}

Then you don't have to add event handlers for each row and your html looks neater. If you don't want any javascript in your html you can even add the handler when page loads:

document.getElementById('dsTable').addEventListener('click',tableclick,false);

??

Here is working code: http://jsfiddle.net/hX4f4/2/

Use str.join:

In [27]: mylist = ['10', '12', '14']

In [28]: print '\n'.join(mylist)
10
12
14

If you need just a left margin, you can try this:

UItextField *textField = [[UITextField alloc] initWithFrame:...];
UIView *leftView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 10, textField.frame.size.height)];
leftView.backgroundColor = textField.backgroundColor;
textField.leftView = leftView;
textField.leftViewMode = UITextFieldViewModeAlways;

It works for me. I hope this may help.

I know the question is old, but in support of the above answers i wanted to share my working code. Just add these two methods to whatever class.The code checks if facebook app is installed, if not installed the url is opened in a browser.And if any errors occur when trying to find the profileId, the page will be opened in a browser. Just pass the url(example, http://www.facebook.com/AlibabaUS) to openUrl: and it will do all the magic. Hope it helps someone!.

NOTE: UrlUtils was the class that had the code for me, you might have to change it to something else to suite your needs.

+(void) openUrlInBrowser:(NSString *) url
{
    if (url.length > 0) {
        NSURL *linkUrl = [NSURL URLWithString:url];
        [[UIApplication sharedApplication] openURL:linkUrl];
    }
}
+(void) openUrl:(NSString *) urlString
{

    //check if facebook app exists
    if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"fb://"]]) {

        // Facebook app installed
        NSArray *tokens = [urlString componentsSeparatedByString:@"/"];
        NSString *profileName = [tokens lastObject];

        //call graph api
        NSURL *apiUrl = [NSURL URLWithString:[NSString stringWithFormat:@"https://graph.facebook.com/%@",profileName]];
        NSData *apiResponse = [NSData dataWithContentsOfURL:apiUrl];

        NSError *error = nil;
        NSDictionary *jsonDict = [NSJSONSerialization JSONObjectWithData:apiResponse options:NSJSONReadingMutableContainers error:&error];

        //check for parse error
        if (error == nil) {

            NSString *profileId = [jsonDict objectForKey:@"id"];

            if (profileId.length > 0) {//make sure id key is actually available
                NSURL *fbUrl = [NSURL URLWithString:[NSString stringWithFormat:@"fb://profile/%@",profileId]];
                [[UIApplication sharedApplication] openURL:fbUrl];
            }
            else{
                [UrlUtils openUrlInBrowser:urlString];
            }

        }
        else{//parse error occured

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

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

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

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

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

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

First of all, you should look gradle.properties and these values have to be true. If you cannot see them you have to write.

android.useAndroidX=true
android.enableJetifier=true

After that you can use AndroidX dependencies in your build.gradle (Module: app). Also, you have to check compileSDKVersion and targetVersion. They should be minimum 28. For example I am using 29.

So, an androidx dependency example:

implementation 'androidx.cardview:cardview:1.0.0'

However be careful because everything is not start with androidx like cardview dependency. For example, old design dependency is:

implementation 'com.android.support:design:27.1.1'

But new design dependency is:

implementation 'com.google.android.material:material:1.3.0'

RecyclerView is:

implementation 'androidx.recyclerview:recyclerview:1.1.0'

So, you have to search and read carefully. Happy code.

@canerkaseler

The accepted answer is correct. However, I needed a little bit more clarity, so in case someone else does too:

Leaflet allows events to fire on virtually anything you do on its map, in this case a marker.

So you could create a marker as suggested by the question above:

L.marker([10.496093,-66.881935]).addTo(map).on('mouseover', onClick);

Then create the onClick function:

function onClick(e) {
    alert(this.getLatLng());
}

Now anytime you mouseover that marker it will fire an alert of the current lat/long.

However, you could use 'click', 'dblclick', etc. instead of 'mouseover' and instead of alerting lat/long you can use the body of onClick to do anything else you want:

L.marker([10.496093,-66.881935]).addTo(map).on('click', function(e) {
    console.log(e.latlng);
});

Here is the documentation: http://leafletjs.com/reference.html#events

ALTER TABLE TableName ADD NewColumnName INTEGER, FOREIGN KEY(NewColumnName) REFERENCES [ForeignKey_TableName](Foreign_Key_Column)

If you are at the root of your working directory, you can do git checkout -- . to check-out all files in the current HEAD and replace your local files.

You can also do git reset --hard to reset your working directory and replace all changes (including the index).

svn delete --keep-local the_file

You can use this simple plugin to add scrollUp and scrollDown to your jQuery

https://github.com/phpust/JQueryScrollDetector

At first I used James Lawruk's method. This however changed all the widths of the td's.

The solution for me was to use white-space: normal on the columns (which was set to white-space: nowrap). This way the text will always break. Using word-wrap: break-word will ensure that everything will break when needed, even halfway through a word.

The CSS will look like this then:

td, th {
    white-space: normal; /* Only needed when it's set differntly somewhere else */
    word-wrap: break-word;
}

This might not always be the desirable solution, as word-wrap: break-word might make your words in the table illegible. It will however keep your table the right width.

By specifying the positions we can achieve this,

.div1 {
  width:300px;
  height: auto;
  background-color: grey;  
  border:1px solid;
  position:relative;
  overflow:auto;
}
.div2 {
  width:150px;
  height:auto;
  background-color: #F4A460;  
  float:left;
}
.div3 {
  width:150px;
  height:100%;
  position:absolute;
  right:0px;
  background-color: #FFFFE0;  
  float:right;
}

but it is not possible to achieve this using float.

I think that the handling of a dialog should be the responsibility of the view, and the view needs to have code to support that.

If you change the ViewModel - View interaction to handle dialogs then the ViewModel is dependant on that implementation. The simplest way to deal with this problem is to make the View responsible for performing the task. If that means showing a dialog then fine, but could also be a status message in the status bar etc.

My point is that the whole point of the MVVM pattern is to separate business logic from the GUI, so you shouldn't be mixing GUI logic (to display a dialog) in the business layer (the ViewModel).

You may be calling fragmentManager.popBackStackImmediate(); when activity is paused. Activity is not finished but is paused and not on foreground. You need to check whether activity is paused or not before popBackStackImmediate().

You can't expect ObjectInputStream to automagically convert text into objects. The hexadecimal 54657374 is "Test" as text. You must be sending it directly as bytes.

Since Git uses curl under the hood, you can use ~/.netrc file with the credentials. For GitHub it would look something like this:

machine github.com
  login <github username>
  password <password OR github access token>

If you choose to use access tokens, it can be generated from:

Settings -> Developer settings -> Personal access tokens

This should also work if you are using Github Enterprise in your own corporation. just put your enterprise github url in the machine field.

There is a simple hack to this:

Insert a hidden input field in the form with an entity which only occur in the character set the server your posting (or doing a GET) to accepts.

Example: If the form is located on a server serving ISO-8859-1 and the form will post to a server expecting UTF-8 insert something like this in the form:

<input name="iehack" type="hidden" value="&#9760;" />

IE will then "detect" that the form contains a UTF-8 character and use UTF-8 when you POST or GET. Strange, but it does work.

An even simpler way to kill all child process of a bash script:

pkill -P $$

The -P flag works the same way with pkill and pgrep - it gets child processes, only with pkill the child processes get killed and with pgrep child PIDs are printed to stdout.

There is a way to insert sections in partial views, though it's not pretty. You need to have access to two variables from the parent View. Since part of your partial view's very purpose is to create that section, it makes sense to require these variables.

Here's what it looks like to insert a section in the partial view:

@model KeyValuePair<WebPageBase, HtmlHelper>
@{
    Model.Key.DefineSection("SectionNameGoesHere", () =>
    {
        Model.Value.ViewContext.Writer.Write("Test");
    });
}

And in the page inserting the partial view...

@Html.Partial(new KeyValuePair<WebPageBase, HtmlHelper>(this, Html))

You can also use this technique to define the contents of a section programmatically in any class.

Enjoy!

There are two ways to look at changing colors for a Node.js console today.

One is through general-purpose libraries that can decorate a text string with color tags, which you then output through the standard console.log.

The top libraries for that today:

• chalk
• colors
• cli-color

And the other way - patching the existing console methods. One such library - manakin lets you automatically set standard colors for all your console methods (log, warn, error and info).

One significant difference from the generic color libraries - it can set colors either globally or locally, while keeping consistent syntax and output format for every Node.js console method, which you then use without having to specify the colors, as they are all set automatically.

I had to change the console background color to white because of eye problems, but the font is gray colored and it makes the messages unreadable. How can I change it?

Specifically for your problem, here's the simplest solution:

var con = require('manakin').global;
con.log.color = 30; // Use black color for console.log

It will set black color for every console.log call in your application. See more color codes.

Default colors as used by manakin:

In order to create dates from free text in Javascript you need to parse it into the Date() object.

You could use Date.parse() which takes free text tries to convert it into a new date but if you have control over the page I would recommend using HTML select boxes instead or a date picker such as the YUI calendar control or the jQuery UI Datepicker.

Once you have a date as other people have pointed out you can use simple arithmetic to subtract the dates and convert it back into a number of days by dividing the number (in seconds) by the number of seconds in a day (60*60*24 = 86400).

Creating an object within class is called tight coupling, Spring removes this dependency by following a design pattern(DI/IOC). In which object of class in passed in constructor rather than creating in class. More over we give super class reference variable in constructor to define more general structure.

With explode function of php

$array=explode(" ",$str); 

This is a quick example for you http://codepad.org/Pbg4n76i

Shouldn't creating a new Runnable class make a new second thread?

No. new Runnable does not create second Thread.

What is the purpose of the Runnable class here apart from being able to pass a Runnable class to postAtTime?

Runnable is posted to Handler. This task runs in the thread, which is associated with Handler.

If Handler is associated with UI Thread, Runnable runs in UI Thread.

If Handler is associated with other HandlerThread, Runnable runs in HandlerThread

To explicitly associate Handler to your MainThread ( UI Thread), write below code.

Handler  mHandler = new Handler(Looper.getMainLooper();

If you write is as below, it uses HandlerThread Looper.

HandlerThread handlerThread = new HandlerThread("HandlerThread");
handlerThread.start();
Handler requestHandler = new Handler(handlerThread.getLooper());

For new you should use delete. For new[] use delete[]. Your second variant is correct.

My problem was actually a problem of bad planning with the JSON object rather than an actual logic issue. What I ended up doing was organize the object as follows, per a suggestion from user2736012.

{
"dialog":
{
    "trunks":[
    {
        "trunk_id" : "1",
        "message": "This is just a JSON Test"
    },
    {
        "trunk_id" : "2",
        "message": "This is a test of a bit longer text. Hopefully this will at the very least create 3 lines and trigger us to go on to another box. So we can test multi-box functionality, too."
    }
    ]
}
}

At that point, I was able to do a fairly simple for loop based on the total number of objects.

var totalMessages = Object.keys(messages.dialog.trunks).length;

    for ( var i = 0; i < totalMessages; i++)
    {
        console.log("ID: " + messages.dialog.trunks[i].trunk_id + " Message " + messages.dialog.trunks[i].message);
    }

My method for getting totalMessages is not supported in all browsers, though. For my project, it actually doesn't matter, but beware of that if you choose to use something similar to this.

Yep, both and and or operators short-circuit -- see the docs.

You need to set ulimit -c. If you have 0 for this parameter a coredump file is not created. So do this: ulimit -c unlimited and check if everything is correct ulimit -a. The coredump file is created when an application has done for example something inappropriate. The name of the file on my system is core.<process-pid-here>.

Store connection string in web.config

It is a good practice to store the connection string for your application in a config file rather than as a hard coded string in your code. The way to do this differs between .NET 2.0 and .NET 3.5 (and above). This article cover both. https://www.connectionstrings.com/store-connection-string-in-webconfig/

Flex is the better way. Just try..

display: flex;

I solve it running as administrator cmd. Cleaning the cache npm cache clean -f And then try to install the package again

You should use this one too:

./gradlew :app:dependencies (Mac and Linux) -With ./

gradlew :app:dependencies (Windows) -Without ./

The libs you are using internally using any other versions of google play service.If yes then remove or update those libs.

Try this.

$('#checkbox').click(function(){
    if (this.checked) {
        $('p').css('color', '#0099ff')
    }
}) 

Sometimes we overkill jquery. Many things can be achieved using jquery with plain javascript.

IF is used to select the field, then the LIKE clause is placed after it:

SELECT  `id` ,  `naam` 
FROM  `klanten` 
WHERE IF(`email` != '', `email`, `email2`) LIKE  '%@domain.nl%'

You can use calc (100% - 100px) on the fluid element, along with display:inline-block for both elements.

Be aware that there should not be any space between the tags, otherwise you will have to consider that space in your calc too.

.left{
    display:inline-block;
    width:100px;
}
.right{
    display:inline-block;
    width:calc(100% - 100px);
}


<div class=“left”></div><div class=“right”></div>

On Linux or Mac, keep is simple and just use sed with the shell. No external libraries required. The following code works on Linux.

const shell = require('child_process').execSync
shell(`sed -i "s!oldString!newString!g" ./yourFile.js`)

The sed syntax is a little different on Mac. I can't test it right now, but I believe you just need to add an empty string after the "-i":

const shell = require('child_process').execSync
shell(`sed -i "" "s!oldString!newString!g" ./yourFile.js`)

The "g" after the final "!" makes sed replace all instances on a line. Remove it, and only the first occurrence per line will be replaced.

             $('#article' + j ).animate({'opacity': '1'}, 500);
          }
    }

});

I am sorting the data by Date and then doing lazy load on window scroll function.

I hope it helps :)

This answer is for those of you looking to Install Bootstrap 3 in your Rails app without using a gem. There are two simple ways to do this that take less than 10 minutes. Pick the one that suites your needs best. Glyphicons and Javascript work and I've tested them with the latest beta of Rails 4.1.0 as well.

1. Using Bootstrap 3 with Rails 4 - The Bootstrap 3 files are copied into the vendor directory of your application.

2. Adding Bootstrap from a CDN to your Rails application - The Bootstrap 3 files are served from the Bootstrap CDN.

Number 2 above is the most flexible. All you need to do is change the version number that is stored in a layout helper. So you can run the Bootstrap version of your choice, whether that is 3.0.0, 3.0.3 or even older Bootstrap 2 releases.

It seems daft, but I think when you use the same bind variable twice you have to set it twice:

cmd.Parameters.Add("VarA", "24");
cmd.Parameters.Add("VarB", "test");
cmd.Parameters.Add("VarB", "test");
cmd.Parameters.Add("VarC", "1234");
cmd.Parameters.Add("VarC", "1234");

Certainly that's true with Native Dynamic SQL in PL/SQL:

SQL> begin
  2     execute immediate 'select * from emp where ename=:name and ename=:name'
  3     using 'KING';
  4  end;
  5  /
begin
*
ERROR at line 1:
ORA-01008: not all variables bound


SQL> begin
  2     execute immediate 'select * from emp where ename=:name and ename=:name' 
  3     using 'KING', 'KING';
  4  end;
  5  /

PL/SQL procedure successfully completed.

You could only convert a JSON array into a CSV file.

Lets say, you have a JSON like the following :

{"infile": [{"field1": 11,"field2": 12,"field3": 13},
            {"field1": 21,"field2": 22,"field3": 23},
            {"field1": 31,"field2": 32,"field3": 33}]}

Lets see the code for converting it to csv :

import java.io.File;
import java.io.IOException;

import org.apache.commons.io.FileUtils;
import org.json.CDL;
import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;

public class JSON2CSV {
    public static void main(String myHelpers[]){
        String jsonString = "{\"infile\": [{\"field1\": 11,\"field2\": 12,\"field3\": 13},{\"field1\": 21,\"field2\": 22,\"field3\": 23},{\"field1\": 31,\"field2\": 32,\"field3\": 33}]}";

        JSONObject output;
        try {
            output = new JSONObject(jsonString);


            JSONArray docs = output.getJSONArray("infile");

            File file=new File("/tmp2/fromJSON.csv");
            String csv = CDL.toString(docs);
            FileUtils.writeStringToFile(file, csv);
        } catch (JSONException e) {
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }        
    }

}

Now you got the CSV generated from JSON.

It should look like this:

field1,field2,field3
11,22,33
21,22,23
31,32,33

The maven dependency was like,

<dependency>
    <groupId>org.json</groupId>
    <artifactId>json</artifactId>
    <version>20090211</version>
</dependency>

Update Dec 13, 2019:

Updating the answer, since now we can support complex JSON Arrays as well.

import java.nio.file.Files;
import java.nio.file.Paths;

import com.github.opendevl.JFlat;

public class FlattenJson {

    public static void main(String[] args) throws Exception {
        String str = new String(Files.readAllBytes(Paths.get("path_to_imput.json")));

        JFlat flatMe = new JFlat(str);

        //get the 2D representation of JSON document
        flatMe.json2Sheet().headerSeparator("_").getJsonAsSheet();

        //write the 2D representation in csv format
        flatMe.write2csv("path_to_output.csv");
    }

}

dependency and docs details are in link

<div class="form-group">
    <label class="font-normal MyText">MyText to copy</label>&nbsp;
    <button type="button" class="btn btn-default btn-xs btnCopy" data="MyText">Copy</button>
</div>


$(".btnCopy").click(function () {
        var element = $(this).attr("data");
        copyToClipboard($('.' + element));
  });

function copyToClipboard(element) {
    var $temp = $("<input>");
    $("body").append($temp);
    $temp.val($(element).text()).select();
    document.execCommand("copy");
    $temp.remove();
}

To add on to what Egon said, simply create your blob called "folder/1.txt", and it will work. No need to create a directory.

his issue is happening due to change of protocol from http to https for central repository. please refer following link for more details. https://support.sonatype.com/hc/en-us/articles/360041287334-Central-501-HTTPS-Required 

In order to fix the problem, copy following into your pom.ml file. This will set the repository url to use https.

char *arr; above statement implies that arr is a character pointer and it can point to either one character or strings of character

& char arr[]; above statement implies that arr is strings of character and can store as many characters as possible or even one but will always count on '\0' character hence making it a string ( e.g. char arr[]= "a" is similar to char arr[]={'a','\0'} )

But when used as parameters in called function, the string passed is stored character by character in formal arguments making no difference.

In my case I used this documentation to associate a key pair with my instance of Elastic Beanstalk

Important

You must create an Amazon EC2 key pair and configure your Elastic Beanstalk–provisioned Amazon EC2 instances to use the Amazon EC2 key pair before you can access your Elastic Beanstalk–provisioned Amazon EC2 instances. You can set up your Amazon EC2 key pairs using the AWS Management Console. For instructions on creating a key pair for Amazon EC2, see the Amazon Elastic Compute Cloud Getting Started Guide.

-(void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component
{
   weightSelected = [pickerArray objectAtIndex:row];
}

('' + 123456789).split('').map( x => +x ).reduce( (a,b) => a+b ) === 45

true

or without map

('' + 123456789).split('').reduce( (a,b) => (+a)+(+b) ) === 45

true

(This is paraphrased from the MS Access help files. I'm sure XL has something similar.) Basically, TimerInterval is a form-level property. Once set, use the sub Form_Timer to carry out your intended action.

Sub Form_Load()
    Me.TimerInterval = 1000 '1000 = 1 second
End Sub

Sub Form_Timer()
    'Do Stuff
End Sub

There is also another straight and more clear way

git commit -m "Title" -m "Description ..........";

There is a new feature in Directory and DirectoryInfo in .NET 4 that allows them to return an IEnumerable instead of an array, and start returning results before reading all the directory contents.

• What's New in the BCL in .NET 4 Beta 1
• Directory.EnumerateFileSystemEntries method overloads

public bool IsDirectoryEmpty(string path)
{
    IEnumerable<string> items = Directory.EnumerateFileSystemEntries(path);
    using (IEnumerator<string> en = items.GetEnumerator())
    {
        return !en.MoveNext();
    }
}

EDIT: seeing that answer again, I realize this code can be made much simpler...

public bool IsDirectoryEmpty(string path)
{
    return !Directory.EnumerateFileSystemEntries(path).Any();
}

If you want to print the last 10 lines, use

tail(dataset, 10)

for the first 10, you could also do

head(dataset, 10)

Example using log4j (src\log4j.xml):

<?xml version="1.0" encoding="UTF-8" ?>

<appender name="CA" class="org.apache.log4j.AsyncAppender">
    <param name="BufferSize" value="512"/>
    <appender-ref ref="CA_OUTPUT"/>
</appender>
<appender name="CA_OUTPUT" class="org.apache.log4j.ConsoleAppender">
    <layout class="org.apache.log4j.PatternLayout">
        <param name="ConversionPattern" value="[%p] %d %c %M - %m%n"/>
    </layout>
</appender>

<logger name="org.hibernate.SQL" additivity="false">
    <level value="DEBUG"/>
    <appender-ref ref="CA"/>
</logger>

<root>
    <level value="WARN"/>
    <appender-ref ref="CA"/>
</root>

It seems like it should be made possible to say:

extra_hosts:
 - "loghost:localhost"

So if the part after the colon (normally an IP address) doesn't start with a digit, then name resolution will be performed to look up an IP for localhost, and add something like to the container's /etc/hosts:

127.0.0.1 loghost

...assuming that localhost resolves to 127.0.0.1 on the host system.

It looks like it'd be really easy to add in docker-compose's source code: compose/config/types.py's parse_extra_hosts function would likely do it.

For docker itself, this would probably be addable in opts/hosts.go's ValidateExtraHost function, though then it's not strictly validating anymore, so the function would be a little misnamed.

It might actually be a little better to add this to docker, not docker-compose - docker-compose might just get it automatically if docker gets it.

Sadly, this would probably require a container bounce to change an IP address.
