Using merge and renaming your t vector as tt (see the PS of Andrie) :

merge(tt,z,by="row.names",all.x=TRUE)[,-(5:8)]

Now if you would work with dataframes instead of matrices, this would even become a whole lot easier :

z <- as.data.frame(z)
tt <- as.data.frame(tt)
merge(tt,z["symbol"],by="row.names",all.x=TRUE)

Lots of these answers no longer apply, so here's mine:

Use the Share Dialog described at the Facebook Dev Page.

Example:

https://www.facebook.com/dialog/share?
  app_id=<your_app_id>
  &display=popup
  &href=https%3A%2F%2Fdevelopers.facebook.com%2Fdocs%2F
  &redirect_uri=https%3A%2F%2Fdevelopers.facebook.com%2Ftools%2Fexplorer

But you have to put in your registered app_id, the href, and a redirect uri.

Most of the references on the web about this issue point out to the fact that you cannot download files via ajax call 'out of the box'. I have seen (hackish) solutions that involve iframes and also solutions like @dcodesmith's that work and are perfectly viable.

Here's another solution I found that works in Angular and is very straighforward.

In the view, wrap the csv download button with <a> tag the following way :

<a target="_self" ng-href="{{csv_link}}">
  <button>download csv</button>
</a>

(Notice the target="_self there, it's crucial to disable Angular's routing inside the ng-app more about it here)

Inside youre controller you can define csv_link the following way :

$scope.csv_link = '/orders' + $window.location.search;

(the $window.location.search is optional and onlt if you want to pass additionaly search query to your server)

Now everytime you click the button, it should start downloading.

You can do it like that but storing a DataSet object in Session is not very efficient. If you have a web app with lots of users it will clog your server memory really fast.

If you really must do it like that I suggest removing it from the session as soon as you don't need the DataSet.

There is no this pointer in a static method. (I don't believe this code will even compile.)

You shouldn't be doing these things in a static method like main(); set things up in a constructor. I didn't compile or run this to see if it actually works, but give it a try.

public class Calc extends JFrame implements ActionListener {

    private Button button1;

    public Calc()
    {
        super();
        this.setSize(100, 100);
        this.setVisible(true);

        this.button1 = new JButton("1");
        this.button1.addActionListener(this);
        this.add(button1);
    }


    public static void main(String[] args) {

        Calc calc = new Calc();
        calc.setVisible(true);
    }

    public void actionPerformed(ActionEvent e) {
        if(e.getSource() == button1)
    }  

}

I'm using doctrine and I have added the driverOptions in my doctrine.local.php :

return array(
'doctrine' => array(
    'connection' => array(
        'orm_default' => array(
            'driverClass' => 'Doctrine\DBAL\Driver\PDOMySql\Driver',
            'params' => array(
                'host' => 'localhost',
                'port' => '3306',
                'user' => 'myusr',
                'password' => 'mypwd',
                'dbname' => 'mydb',
                'driverOptions' => array(
                    PDO::MYSQL_ATTR_INIT_COMMAND => "SET sql_mode=(SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY',''))"
                ),
            ),
        ),
    ),
));

In phpmyadmin the user needs SUPER activated in the privileges.

Personally, I like the 'batch' command.

$ batch
> mycommand -x arg1 -y arg2 -z arg3
> ^D

This stuffs it in to the background, and then mails the results to you. It's a part of cron.

preg_match('/'.preg_quote('^\'£$%^&*()}{@#~?><,@|-=-_+-¬', '/').'/', $string);

string keyName=@"HKEY_LOCAL_MACHINE\System\CurrentControlSet\services\pcmcia";
string valueName="Start";
if (Registry.GetValue(keyName, valueName, null) == null)
{
     //code if key Not Exist
}
else
{
     //code if key Exist
}

putting a quick example, should be a sufficient starting point

Code in Form A

public event EventHandler<EventArgs> RowAdded;

private void btnRowAdded_Click(object sender, EventArgs e)
{
     // insert data
     // if successful raise event
     OnRowAddedEvent();
}

private void OnRowAddedEvent()
{
     var listener = RowAdded;
     if (listener != null)
         listener(this, EventArgs.Empty);
}

Code in Form B

private void button1_Click(object sender, EventArgs e)
{
     var frm = new Form2();
     frm.RowAdded += new EventHandler<EventArgs>(frm_RowAdded);
     frm.Show();
}

void frm_RowAdded(object sender, EventArgs e)
{
     // retrieve data again
}

You can even consider creating your own EventArgs class that can contain the newly added data. You can then use this to directly add the data to a new row in DatagridView

I would agree that it were nice if such a function was part of the included batteries. But it isn't, as far as I know. Here is a version for arbitrary axes, and giving optimal performance.

import numpy as np

def normalized(a, axis=-1, order=2):
    l2 = np.atleast_1d(np.linalg.norm(a, order, axis))
    l2[l2==0] = 1
    return a / np.expand_dims(l2, axis)

A = np.random.randn(3,3,3)
print(normalized(A,0))
print(normalized(A,1))
print(normalized(A,2))

print(normalized(np.arange(3)[:,None]))
print(normalized(np.arange(3)))

When the normType is NORM_MINMAX, cv::normalize normalizes _src in such a way that the min value of dst is alpha and max value of dst is beta. cv::normalize does its magic using only scales and shifts (i.e. adding constants and multiplying by constants).

CV_8UC1 says how many channels dst has.

The documentation here is pretty clear: http://docs.opencv.org/modules/core/doc/operations_on_arrays.html#normalize

I had the same problem shadow/elevation not showing on Android with elevation:2. Then i noticed that the view element is fool width, so I added margin:2 to the view element and elevation properly appeared.

Style:

    margin: 2,
    shadowColor: '#000',
    shadowOffset: {
      width: 0,
      height: 1
    },
    shadowOpacity: 0.2,
    shadowRadius: 1.41,
    elevation: 2

Android:

iOS:

Private Function GetIPv4Address() As String
    GetIPv4Address = String.Empty
    Dim strHostName As String = System.Net.Dns.GetHostName()
    Dim iphe As System.Net.IPHostEntry = System.Net.Dns.GetHostEntry(strHostName)

    For Each ipheal As System.Net.IPAddress In iphe.AddressList
        If ipheal.AddressFamily = System.Net.Sockets.AddressFamily.InterNetwork Then
            GetIPv4Address = ipheal.ToString()
        End If
    Next

You can scale the image with pygame.transform.scale:

import pygame
picture = pygame.image.load(filename)
picture = pygame.transform.scale(picture, (1280, 720))

You can then get the bounding rectangle of picture with

rect = picture.get_rect()

and move the picture with

rect = rect.move((x, y))
screen.blit(picture, rect)

where screen was set with something like

screen = pygame.display.set_mode((1600, 900))

To allow your widgets to adjust to various screen sizes, you could make the display resizable:

import os
import pygame
from pygame.locals import *

pygame.init()
screen = pygame.display.set_mode((500, 500), HWSURFACE | DOUBLEBUF | RESIZABLE)
pic = pygame.image.load("image.png")
screen.blit(pygame.transform.scale(pic, (500, 500)), (0, 0))
pygame.display.flip()
while True:
    pygame.event.pump()
    event = pygame.event.wait()
    if event.type == QUIT:
        pygame.display.quit()
    elif event.type == VIDEORESIZE:
        screen = pygame.display.set_mode(
            event.dict['size'], HWSURFACE | DOUBLEBUF | RESIZABLE)
        screen.blit(pygame.transform.scale(pic, event.dict['size']), (0, 0))
        pygame.display.flip()

Here's some code that works for us. We found MSIE to be hit and miss with DomContentLoaded, there appears to be some delay when no additional resources are cached (up to 300ms based on our console logging), and it triggers too fast when they are cached. So we resorted to a fallback for MISE. You also want to trigger the doStuff() function whether DomContentLoaded triggers before or after your external JS files.

// detect MSIE 9,10,11, but not Edge
ua=navigator.userAgent.toLowerCase();isIE=/msie/.test(ua);

function doStuff(){
    //
}
if(isIE){
    // play it safe, very few users, exec ur JS when all resources are loaded
    window.onload=function(){doStuff();}
} else {
    // add event listener to trigger your function when DOMContentLoaded
    if(document.readyState==='loading'){
        document.addEventListener('DOMContentLoaded',doStuff);
    } else {
        // DOMContentLoaded already loaded, so better trigger your function
        doStuff();
    }
}

If you have to ask this question then you're probably unfamiliar with what most web applications/services do. You're probably thinking that all software do this:

user do an action
       ¦
       v
 application start processing action
   +--> loop ...
          +--> busy processing
 end loop
   +--> send result to user

However, this is not how web applications, or indeed any application with a database as the back-end, work. Web apps do this:

user do an action
       ¦
       v
 application start processing action
   +--> make database request
          +--> do nothing until request completes
 request complete
   +--> send result to user

In this scenario, the software spend most of its running time using 0% CPU time waiting for the database to return.

Multithreaded network app:

Multithreaded network apps handle the above workload like this:

request --> spawn thread
              +--> wait for database request
                     +--> answer request
request --> spawn thread
              +--> wait for database request
                     +--> answer request
request --> spawn thread
              +--> wait for database request
                     +--> answer request

So the thread spend most of their time using 0% CPU waiting for the database to return data. While doing so they have had to allocate the memory required for a thread which includes a completely separate program stack for each thread etc. Also, they would have to start a thread which while is not as expensive as starting a full process is still not exactly cheap.

Singlethreaded event loop

Since we spend most of our time using 0% CPU, why not run some code when we're not using CPU? That way, each request will still get the same amount of CPU time as multithreaded applications but we don't need to start a thread. So we do this:

request --> make database request
request --> make database request
request --> make database request
database request complete --> send response
database request complete --> send response
database request complete --> send response

In practice both approaches return data with roughly the same latency since it's the database response time that dominates the processing.

The main advantage here is that we don't need to spawn a new thread so we don't need to do lots and lots of malloc which would slow us down.

Magic, invisible threading

The seemingly mysterious thing is how both the approaches above manage to run workload in "parallel"? The answer is that the database is threaded. So our single-threaded app is actually leveraging the multi-threaded behaviour of another process: the database.

Where singlethreaded approach fails

A singlethreaded app fails big if you need to do lots of CPU calculations before returning the data. Now, I don't mean a for loop processing the database result. That's still mostly O(n). What I mean is things like doing Fourier transform (mp3 encoding for example), ray tracing (3D rendering) etc.

Another pitfall of singlethreaded apps is that it will only utilise a single CPU core. So if you have a quad-core server (not uncommon nowdays) you're not using the other 3 cores.

Where multithreaded approach fails

A multithreaded app fails big if you need to allocate lots of RAM per thread. First, the RAM usage itself means you can't handle as many requests as a singlethreaded app. Worse, malloc is slow. Allocating lots and lots of objects (which is common for modern web frameworks) means we can potentially end up being slower than singlethreaded apps. This is where node.js usually win.

One use-case that end up making multithreaded worse is when you need to run another scripting language in your thread. First you usually need to malloc the entire runtime for that language, then you need to malloc the variables used by your script.

So if you're writing network apps in C or go or java then the overhead of threading will usually not be too bad. If you're writing a C web server to serve PHP or Ruby then it's very easy to write a faster server in javascript or Ruby or Python.

Hybrid approach

Some web servers use a hybrid approach. Nginx and Apache2 for example implement their network processing code as a thread pool of event loops. Each thread runs an event loop simultaneously processing requests single-threaded but requests are load-balanced among multiple threads.

Some single-threaded architectures also use a hybrid approach. Instead of launching multiple threads from a single process you can launch multiple applications - for example, 4 node.js servers on a quad-core machine. Then you use a load balancer to spread the workload amongst the processes.

In effect the two approaches are technically identical mirror-images of each other.

Since most sessions are stored in a COOKIE (as per the above comments and solutions) it is important to make sure the COOKIE is flagged as a SECURE one (front C#):

myHttpOnlyCookie.HttpOnly = true;

and/or vie php.ini (default TRUE since php 5.3):

session.cookie_httponly = True

Assuming your byte1 is a byte(8bits), When you do a bitwise AND of a byte with 0xFF, you are getting the same byte.

So byte1 is the same as byte1 & 0xFF

Say byte1 is 01001101 , then byte1 & 0xFF = 01001101 & 11111111 = 01001101 = byte1

If byte1 is of some other type say integer of 4 bytes, bitwise AND with 0xFF leaves you with least significant byte(8 bits) of the byte1.

The reason you can't make sense of how to accomplish what you're trying to do is probably that what you're trying to do doesn't really make sense. You want to call getInstance(x) with different arguments, but always return the same object? What behavior is it you want when you call getInstance(2) and then getInstance(5)?

If you want the same object but for its internal value to be different, which is the only way it's still a singleton, then you don't need to care about the constructor at all; you just set the value in getInstance() on the object's way out. Of course, you understand that all your other references to the singleton now have a different internal value.

If you want getInstance(2) and getInstance(5) to return different objects, on the other hand, you're not using the Singleton pattern, you're using the Factory pattern.

I think you can try this:

<a th:href="${'/category/edit/' + {category.id}}">view</a>

Or if you have "idCategory" this:

<a th:href="${'/category/edit/' + {category.idCategory}}">view</a>

If you do not have too many folders then I suggest you use if statements to choose an upload folder depending on the user input details. E.g.

String user= request.getParameter("username");
if (user=="Alfred"){
//Path A;
}
if (user=="other"){
//Path B;
}

Use: Path.GetFileName Method

var onlyFileName = System.IO.Path.GetFileName(ofd.FileName);

Updating the ~/.profile or ~/.bash_profile does not work sometimes. I just deleted JDK 6 and sourced .bash_profile.

Try running this:

sudo rm -rd jdk1.6.0_* #it may not let you delete without sudo

Then, modify/add your JAVA_HOME and PATH variables.

source ~/.bash_profile #assuming you've updated $JAVA_HOME and $PATH

Dozer is a Java Bean to Java Bean mapper that recursively copies data from one object to another. Typically, these Java Beans will be of different complex types.

Dozer supports simple property mapping, complex type mapping, bi-directional mapping, implicit-explicit mapping, as well as recursive mapping. This includes mapping collection attributes that also need mapping at the element level.

if($('#postcode_div').is(':visible')) {
    if($('#postcode_text').val()=='') {
        $('#spanPost').text('\u00a0');
    } else {
        $('#spanPost').text($('#postcode_text').val());
}

Try invoking your command with Invoke-Expression:

Invoke-Expression $cmd1

Here is a working example on my machine:

$cmd = "& 'C:\Program Files\7-zip\7z.exe' a -tzip c:\temp\test.zip c:\temp\test.txt"
Invoke-Expression $cmd

iex is an alias for Invoke-Expression so you could do:

iex $cmd1

Good Luck...

To my opinion the best option to route to css & js use the following code:

<link rel="stylesheet" type="text/css" href="{{ URL::to('route/to/css') }}">

So if you have css file called main.css inside of css folder in public folder it should be the following:

<link rel="stylesheet" type="text/css" href="{{ URL::to('css/main.css') }}">

I would recommend using CSS for this. You should create a CSS rule to enforce the centering, for example:

.ui-helper-center {
    text-align: center;
}

And then add the ui-helper-center class to the table cells for which you wish to control the alignment:

<td class="ui-helper-center">Content</td>

EDIT: Since this answer was accepted, I felt obligated to edit out the parts that caused a flame-war in the comments, and to not promote poor and outdated practices.

See Gabe's answer for how to include the CSS rule into your page.

The reason this convention came into practice is because on UNIX-like operating systems a newline character is treated as a line terminator and/or message boundary (this includes piping between processes, line buffering, etc.).

Consider, for example, that a file with just a newline character is treated as a single, empty line. Conversely, a file with a length of zero bytes is actually an empty file with zero lines. This can be confirmed according to the wc -l command.

Altogether, this behavior is reasonable because there would be no other way to distinguish between an empty text file versus a text file with a single empty line if the \n character was merely a line-separator rather than a line-terminator. Thus, valid text files should always end with a newline character. The only exception is if the text file is intended to be empty (no lines).

Wherever possible, please don't use SCREEN_ORIENTATION_LANDSCAPE or SCREEN_ORIENTATION_PORTRAIT. Instead use:

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR_LANDSCAPE);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR_PORTRAIT);

These allow the user to orient the device to either landscape orientation, or either portrait orientation, respectively. If you've ever had to play a game with a charging cable being driven into your stomach, then you know exactly why having both orientations available is important to the user.

Note: For phones, at least several that I've checked, it only allows the "right side up" portrait mode, however, SENSOR_PORTRAIT works properly on tablets.

Note: this feature was introduced in API Level 9, so if you must support 8 or lower (not likely at this point), then instead use:

setRequestedOrientation(Build.VERSION.SDK_INT < 9 ?
                        ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE :
                        ActivityInfo.SCREEN_ORIENTATION_SENSOR_LANDSCAPE);
setRequestedOrientation(Build.VERSION.SDK_INT < 9 ?
                        ActivityInfo.SCREEN_ORIENTATION_PORTRAIT :
                        ActivityInfo.SCREEN_ORIENTATION_SENSOR_PORTRAIT);

A long time ago:

Call any of these

byte[] org.apache.commons.io.FileUtils.readFileToByteArray(File file)
byte[] org.apache.commons.io.IOUtils.toByteArray(InputStream input) 

From

http://commons.apache.org/io/

If the library footprint is too big for your Android app, you can just use relevant classes from the commons-io library

Today (Java 7+ or Android API Level 26+)

Luckily, we now have a couple of convenience methods in the nio packages. For instance:

byte[] java.nio.file.Files.readAllBytes(Path path)

Javadoc here

You can use dict.get()

value = d.get(key)

which will return None if key is not in d. You can also provide a different default value that will be returned instead of None:

value = d.get(key, "empty")

I prefer a more generic method in which may be user doesn't prefer to give key 'results'. You can still flatten it by using a recursive approach of finding key having nested data or if you have key but your JSON is very nested. It is something like:

from pandas import json_normalize

def findnestedlist(js):
    for i in js.keys():
        if isinstance(js[i],list):
            return js[i]
    for v in js.values():
        if isinstance(v,dict):
            return check_list(v)


def recursive_lookup(k, d):
    if k in d:
        return d[k]
    for v in d.values():
        if isinstance(v, dict):
            return recursive_lookup(k, v)
    return None

def flat_json(content,key):
    nested_list = []
    js = json.loads(content)
    if key is None or key == '':
        nested_list = findnestedlist(js)
    else:
        nested_list = recursive_lookup(key, js)
    return json_normalize(nested_list,sep="_")

key = "results" # If you don't have it, give it None

csv_data = flat_json(your_json_string,root_key)
print(csv_data)

A Record lets you create a new type from a Union. The values in the Union are used as attributes of the new type.

For example, say I have a Union like this:

type CatNames = "miffy" | "boris" | "mordred";

Now I want to create an object that contains information about all the cats, I can create a new type using the values in the CatName Union as keys.

type CatList = Record<CatNames, {age: number}>

If I want to satisfy this CatList, I must create an object like this:

const cats:CatList = {
  miffy: { age:99 },
  boris: { age:16 },
  mordred: { age:600 }
}

You get very strong type safety:

• If I forget a cat, I get an error.
• If I add a cat that's not allowed, I get an error.
• If I later change CatNames, I get an error. This is especially useful because CatNames is likely imported from another file, and likely used in many places.

Real-world React example.

I used this recently to create a Status component. The component would receive a status prop, and then render an icon. I've simplified the code quite a lot here for illustrative purposes

I had a union like this:

type Statuses = "failed" | "complete";

I used this to create an object like this:

const icons: Record<
  Statuses,
  { iconType: IconTypes; iconColor: IconColors }
> = {
  failed: {
    iconType: "warning",
    iconColor: "red"
  },
  complete: {
    iconType: "check",
    iconColor: "green"
  };

I could then render by destructuring an element from the object into props, like so:

const Status = ({status}) => <Icon {...icons[status]} />

If the Statuses union is later extended or changed, I know my Status component will fail to compile and I'll get an error that I can fix immediately. This allows me to add additional error states to the app.

Note that the actual app had dozens of error states that were referenced in multiple places, so this type safety was extremely useful.

If your arrays are sorted, this should run in O(n), where n is min( a.length, b.length )

function intersect_1d( a, b ){
    var out=[], ai=0, bi=0, acurr, bcurr, last=Number.MIN_SAFE_INTEGER;
    while( ( acurr=a[ai] )!==undefined && ( bcurr=b[bi] )!==undefined ){
        if( acurr < bcurr){
            if( last===acurr ){
                out.push( acurr );
            }
            last=acurr;
            ai++;
        }
        else if( acurr > bcurr){
            if( last===bcurr ){
                out.push( bcurr );
            }
            last=bcurr;
            bi++;
        }
        else {
            out.push( acurr );
            last=acurr;
            ai++;
            bi++;
        }
    }
    return out;
}

Change the USB cable !!!! I can't explain this technically, however after a lot of trial and error, this what have worked for me.

Formats

Python docstrings can be written following several formats as the other posts showed. However the default Sphinx docstring format was not mentioned and is based on reStructuredText (reST). You can get some information about the main formats in this blog post.

Note that the reST is recommended by the PEP 287

There follows the main used formats for docstrings.

- Epytext

Historically a javadoc like style was prevalent, so it was taken as a base for Epydoc (with the called Epytext format) to generate documentation.

Example:

"""
This is a javadoc style.

@param param1: this is a first param
@param param2: this is a second param
@return: this is a description of what is returned
@raise keyError: raises an exception
"""

- reST

Nowadays, the probably more prevalent format is the reStructuredText (reST) format that is used by Sphinx to generate documentation. Note: it is used by default in JetBrains PyCharm (type triple quotes after defining a method and hit enter). It is also used by default as output format in Pyment.

Example:

"""
This is a reST style.

:param param1: this is a first param
:param param2: this is a second param
:returns: this is a description of what is returned
:raises keyError: raises an exception
"""

- Google

Google has their own format that is often used. It also can be interpreted by Sphinx (ie. using Napoleon plugin).

Example:

"""
This is an example of Google style.

Args:
    param1: This is the first param.
    param2: This is a second param.

Returns:
    This is a description of what is returned.

Raises:
    KeyError: Raises an exception.
"""

Even more examples

- Numpydoc

Note that Numpy recommend to follow their own numpydoc based on Google format and usable by Sphinx.

"""
My numpydoc description of a kind
of very exhautive numpydoc format docstring.

Parameters
----------
first : array_like
    the 1st param name `first`
second :
    the 2nd param
third : {'value', 'other'}, optional
    the 3rd param, by default 'value'

Returns
-------
string
    a value in a string

Raises
------
KeyError
    when a key error
OtherError
    when an other error
"""

Converting/Generating

It is possible to use a tool like Pyment to automatically generate docstrings to a Python project not yet documented, or to convert existing docstrings (can be mixing several formats) from a format to an other one.

Note: The examples are taken from the Pyment documentation

Here you go.

if (!is_dir('path/to/directory')) {
    if (!mkdir('path/to/directory', 0777, true) && !is_dir('path/to/directory')) {
        throw new \RuntimeException(sprintf('Directory "%s" was not created', 'path/to/directory'));
    }
}

This is a self-compiled bat/.net hybrid (should be saved as .BAT) that can be used on any system that have installed .net framework (it's a rare thing to see an windows without .NET framework even for the oldest XP/2003 installations) . It uses jscript.net compiler to create an exe capable to print strings with different background/foreground color only for the current line.

@if (@X)==(@Y) @end /* JScript comment

@LiviuT's answer is awesome, but seems to leave lots of folks wondering how to re-access the handler's tear-down function from another $scope or function, if you want to destroy it from a place other than where it was created. @?????? ?????????'s answer works just great, but isn't very idiomatic. (And relies on what's supposed to be a private implementation detail, which could change any time.) And from there, it just gets more complicated...

I think the easy answer here is to simply carry a reference to the tear-down function (offCallMeFn in his example) in the handler itself, and then call it based on some condition; perhaps an arg that you include on the event you $broadcast or $emit. Handlers can thus tear down themselves, whenever you want, wherever you want, carrying around the seeds of their own destruction. Like so:

// Creation of our handler:
var tearDownFunc = $rootScope.$on('demo-event', function(event, booleanParam) {
    var selfDestruct = tearDownFunc;
    if (booleanParam === false) {
        console.log('This is the routine handler here. I can do your normal handling-type stuff.')
    }
    if (booleanParam === true) {
        console.log("5... 4... 3... 2... 1...")
        selfDestruct();
    }
});

// These two functions are purely for demonstration
window.trigger = function(booleanArg) {
    $scope.$emit('demo-event', booleanArg);
}
window.check = function() {
    // shows us where Angular is stashing our handlers, while they exist
    console.log($rootScope.$$listeners['demo-event'])
};

// Interactive Demo:

>> trigger(false);
// "This is the routine handler here. I can do your normal handling-type stuff."

>> check();
// [function] (So, there's a handler registered at this point.)  

>> trigger(true);
// "5... 4... 3... 2... 1..."

>> check();
// [null] (No more handler.)

>> trigger(false);
// undefined (He's dead, Jim.)

Two thoughts:

1. This is a great formula for a run-once handler. Just drop the conditionals and run selfDestruct as soon as it has completed its suicide mission.
2. I wonder about whether the originating scope will ever be properly destroyed and garbage-collected, given that you're carrying references to closured variables. You'd have to use a million of these to even have it be a memory problem, but I'm curious. If anybody has any insight, please share.

Your model is @Messages, change it to @message.

To change it like you should use migration:

def change   rename_table :old_table_name, :new_table_name end 

Of course do not create that file by hand but use rails generator:

rails g migration ChangeMessagesToMessage 

That will generate new file with proper timestamp in name in 'db dir. Then run:

rake db:migrate 

And your app should be fine since then.

The for loop in list comprehension takes time and makes it slow. It is better to use numpy parameters (low, high, size, ..etc)

import numpy as np
import time
rang = 10000
tic = time.time()
for i in range(rang):
    sampl = np.random.uniform(low=0, high=2, size=(182))
print("it took: ", time.time() - tic)

tic = time.time()
for i in range(rang):
    ran_floats = [np.random.uniform(0,2) for _ in range(182)]
print("it took: ", time.time() - tic)

sample output:

('it took: ', 0.06406784057617188)

('it took: ', 1.7253198623657227)

You can use ng-change instead of ng-click:

<!doctype html>
<html>
<head>
  <script src="http://code.angularjs.org/1.2.3/angular.min.js"></script>
  <script>
        var app = angular.module('myapp', []);
        app.controller('mainController', function($scope) {
          $scope.vm = {};
          $scope.vm.myClick = function($event) {
                alert($event);
          }
        });     
  </script>  
</head>
<body ng-app="myapp">
  <div ng-controller="mainController">
    <input type="checkbox" ng-model="vm.myChkModel" ng-change="vm.myClick(vm.myChkModel)">
  </div>
</body>
</html>

Anyway you need 'Year'.

In some engineering fields, you have fixed day and month and year can be variable. But that day and month are important for beginning calculation without considering which year you are. Your user, for example, only should select a day and a month and providing year is up to you.

You can create a custom combobox using this: Customizable ComboBox Drop-Down.

1- In VS create a user control.

2- See the code in the link above for impelemnting that control.

3- Create another user control and place in it 31 button or label and above them place a label to show months.

4- Place the control in step 3 in your custom combobox.

5- Place the control in setp 4 in step 1.

You now have a control with only days and months. You can use any year that you have in your database or ....

Transient variables in Java are never serialized.

You might be interested in Apache Bench tool which is basically used to do simple load testing.

example :

ab -n 500 -c 20 http://www.example.com/

n = total number of request, c = number of concurrent request

Add android:enabled="true" to BottomNavigationMenu Items.

And then set bottomNavigationView.setOnNavigationItemSelectedListener(mListener) and set it as selected by doing bottomNavigationView.selectedItemId = R.id.your_menu_id

There are right answers but I just want to add one more option (requires downtime):

1. Stop Redis.
2. Delete RDB file (find location in redis.conf).
3. Start Redis.

The Accept Ranges header (the bit in writeHead()) is required for the HTML5 video controls to work.

I think instead of just blindly send the full file, you should first check the Accept Ranges header in the REQUEST, then read in and send just that bit. fs.createReadStream support start, and end option for that.

So I tried an example and it works. The code is not pretty but it is easy to understand. First we process the range header to get the start/end position. Then we use fs.stat to get the size of the file without reading the whole file into memory. Finally, use fs.createReadStream to send the requested part to the client.

var fs = require("fs"),
    http = require("http"),
    url = require("url"),
    path = require("path");

http.createServer(function (req, res) {
  if (req.url != "/movie.mp4") {
    res.writeHead(200, { "Content-Type": "text/html" });
    res.end('<video src="http://localhost:8888/movie.mp4" controls></video>');
  } else {
    var file = path.resolve(__dirname,"movie.mp4");
    fs.stat(file, function(err, stats) {
      if (err) {
        if (err.code === 'ENOENT') {
          // 404 Error if file not found
          return res.sendStatus(404);
        }
      res.end(err);
      }
      var range = req.headers.range;
      if (!range) {
       // 416 Wrong range
       return res.sendStatus(416);
      }
      var positions = range.replace(/bytes=/, "").split("-");
      var start = parseInt(positions[0], 10);
      var total = stats.size;
      var end = positions[1] ? parseInt(positions[1], 10) : total - 1;
      var chunksize = (end - start) + 1;

      res.writeHead(206, {
        "Content-Range": "bytes " + start + "-" + end + "/" + total,
        "Accept-Ranges": "bytes",
        "Content-Length": chunksize,
        "Content-Type": "video/mp4"
      });

      var stream = fs.createReadStream(file, { start: start, end: end })
        .on("open", function() {
          stream.pipe(res);
        }).on("error", function(err) {
          res.end(err);
        });
    });
  }
}).listen(8888);

Try This

Instead of removing all assertions, you should still check for things like a person being his/her own parent or other impossible situations and present an error. Maybe issue a warning if it is unlikely so the user can still detect common input errors, but it will work if everything is correct.

I would store the data in a vector with a permanent integer for each person and store the parents and children in person objects where the said int is the index of the vector. This would be pretty fast to go between generations (but slow for things like name searches). The objects would be in order of when they were created.

It shouldn't be HTTP headers if the file has been downloaded successfully and it's the same file that you can open from OI.

A shot in the dark, but could it be that you are not allowing installation from unknown sources, and that OI is somehow bypassing that?

SUMMARY:

I provide here a no-jQuery cross-browser desktop-and-mobile ability to consistently respond to range/slider interactions, something not possible in current browsers. It essentially forces all browsers to emulate IE11's on("change"... event for either their on("change"... or on("input"... events. The new function is...

function onRangeChange(r,f) {
  var n,c,m;
  r.addEventListener("input",function(e){n=1;c=e.target.value;if(c!=m)f(e);m=c;});
  r.addEventListener("change",function(e){if(!n)f(e);});
}

...where r is your range input element and f is your listener. The listener will be called after any interaction that changes the range/slider value but not after interactions that do not change that value, including initial mouse or touch interactions at the current slider position or upon moving off either end of the slider.

Problem:

As of early June 2016, different browsers differ in terms of how they respond to range/slider usage. Five scenarios are relevant:

1. initial mouse-down (or touch-start) at the current slider position
2. initial mouse-down (or touch-start) at a new slider position
3. any subsequent mouse (or touch) movement after 1 or 2 along the slider
4. any subsequent mouse (or touch) movement after 1 or 2 past either end of the slider
5. final mouse-up (or touch-end)

The following table shows how at least three different desktop browsers differ in their behaviour with respect to which of the above scenarios they respond to:

Solution:

The onRangeChange function provides a consistent and predictable cross-browser response to range/slider interactions. It forces all browsers to behave according to the following table:

In IE11, the code essentially allows everything to operate as per the status quo, i.e. it allows the "change" event to function in its standard way and the "input" event is irrelevant as it never fires anyway. In other browsers, the "change" event is effectively silenced (to prevent extra and sometimes not-readily-apparent events from firing). In addition, the "input" event fires its listener only when the range/slider's value changes. For some browsers (e.g. Firefox) this occurs because the listener is effectively silenced in scenarios 1, 4 and 5 from the above list.

(If you truly require a listener to be activated in either scenario 1, 4 and/or 5 you could try incorporating "mousedown"/"touchstart", "mousemove"/"touchmove" and/or "mouseup"/"touchend" events. Such a solution is beyond the scope of this answer.)

Functionality in Mobile Browsers:

I have tested this code in desktop browsers but not in any mobile browsers. However, in another answer on this page MBourne has shown that my solution here "...appears to work in every browser I could find (Win desktop: IE, Chrome, Opera, FF; Android Chrome, Opera and FF, iOS Safari)". (Thanks MBourne.)

Usage:

To use this solution, include the onRangeChange function from the summary above (simplified/minified) or the demo code snippet below (functionally identical but more self-explanatory) in your own code. Invoke it as follows:

onRangeChange(myRangeInputElmt, myListener);

where myRangeInputElmt is your desired <input type="range"> DOM element and myListener is the listener/handler function you want invoked upon "change"-like events.

Your listener may be parameter-less if desired or may use the event parameter, i.e. either of the following would work, depending on your needs:

var myListener = function() {...

or

var myListener = function(evt) {...

(Removing the event listener from the input element (e.g. using removeEventListener) is not addressed in this answer.)

Demo Description:

In the code snippet below, the function onRangeChange provides the universal solution. The rest of the code is simply an example to demonstrate its use. Any variable that begins with my... is irrelevant to the universal solution and is only present for the sake of the demo.

The demo shows the range/slider value as well as the number of times the standard "change", "input" and custom "onRangeChange" events have fired (rows A, B and C respectively). When running this snippet in different browsers, note the following as you interact with the range/slider:

• In IE11, the values in rows A and C both change in scenarios 2 and 3 above while row B never changes.
• In Chrome and Safari, the values in rows B and C both change in scenarios 2 and 3 while row A changes only for scenario 5.
• In Firefox, the value in row A changes only for scenario 5, row B changes for all five scenarios, and row C changes only for scenarios 2 and 3.
• In all of the above browsers, the changes in row C (the proposed solution) are identical, i.e. only for scenarios 2 and 3.

Credit:

While the implementation here is largely my own, it was inspired by MBourne's answer. That other answer suggested that the "input" and "change" events could be merged and that the resulting code would work in both desktop and mobile browsers. However, the code in that answer results in hidden "extra" events being fired, which in and of itself is problematic, and the events fired differ between browsers, a further problem. My implementation here solves those problems.

Because JavaScript is such a small language, yet with incredible complexity, you should be able to ask relatively basic questions and find out if they are really that good based on their answers. For instance, my standard first question to gauge the rest of the interview is:

In JavaScript, what is the difference between var x = 1 and x = 1? Answer in as much or as little detail as you feel comfortable.

Novice JS programmers might have a basic answer about locals vs globals. Intermediate JS guys should definitely have that answer, and should probably mention function-level scope. Anyone calling themselves an "advanced" JS programmer should be prepared to talk about locals, implied globals, the window object, function-scope, declaration hoisting, and scope chains. Furthermore, I'd love to hear about [[DontDelete]], hoisting precedence (parameters vs var vs function), and undefined.

Another good question is to ask them to write a sum() function that accepts any number of arguments, and returns their sum. Then, ask them to use that function (without modification) to sum all the values in an array. They should write a function that looks like this:

function sum() {
  var i, l, result = 0;
  for (i = 0, l = arguments.length; i < l; i++) {
    result += arguments[i];
  }
  return result;
}
sum(1,2,3); // 6

And they should invoke it on your array like this (context for apply can be whatever, I usually use null in that case):

var data = [1,2,3];
sum.apply(null, data); // 6

If they've got those answers, they probably know their JavaScript. You should then proceed to asking them about non-JS specific stuff like testing, workflows, version control, etc. to find out if they're a good programmer.

There is a command line program to convert any Java project into a SBT/Maven project.

It resolves all jars and tries to figure out the correct version based on SHA checksum, classpath or filename. Then it tries to compile the sources until it finds a working configuration. Custom tasks to execute per dependency configuration can be given too.

Note that datetime.datetime.fromtimestamp(timestamp) and .utcfromtimestamp(timestamp) fail on windows for dates before Jan. 1, 1970 while negative unix timestamps seem to work on unix-based platforms. The docs say this:

"This may raise ValueError, if the timestamp is out of the range of values supported by the platform C gmtime() function. It’s common for this to be restricted to years in 1970 through 2038"

Check out the MSDN article Asynchronous Programming with Async and Await if you can afford to play with new stuff. It was added to .NET 4.5.

Example code snippet from the link (which is itself from this MSDN sample code project):

// Three things to note in the signature: 
//  - The method has an async modifier.  
//  - The return type is Task or Task<T>. (See "Return Types" section.)
//    Here, it is Task<int> because the return statement returns an integer. 
//  - The method name ends in "Async."
async Task<int> AccessTheWebAsync()
{ 
    // You need to add a reference to System.Net.Http to declare client.
    HttpClient client = new HttpClient();

    // GetStringAsync returns a Task<string>. That means that when you await the 
    // task you'll get a string (urlContents).
    Task<string> getStringTask = client.GetStringAsync("http://msdn.microsoft.com");

    // You can do work here that doesn't rely on the string from GetStringAsync.
    DoIndependentWork();

    // The await operator suspends AccessTheWebAsync. 
    //  - AccessTheWebAsync can't continue until getStringTask is complete. 
    //  - Meanwhile, control returns to the caller of AccessTheWebAsync. 
    //  - Control resumes here when getStringTask is complete.  
    //  - The await operator then retrieves the string result from getStringTask. 
    string urlContents = await getStringTask;

    // The return statement specifies an integer result. 
    // Any methods that are awaiting AccessTheWebAsync retrieve the length value. 
    return urlContents.Length;
}

Quoting:

If AccessTheWebAsync doesn't have any work that it can do between calling GetStringAsync and awaiting its completion, you can simplify your code by calling and awaiting in the following single statement.

string urlContents = await client.GetStringAsync();

More details are in the link.

Set universal_newlines to True, i.e.

You may use sshfs:

$ sshfs user@ip:/<remote-path> <local-mount-path>
$ docker save <image-id> > <local-mount-path>/myImage.tar

Try putting your image into a container like so:

HTML:

<div>
    <img src="http://www.testimoniesofheavenandhell.com/Animal-Pictures/wp-content/uploads/2013/04/Dog-Animal-Picture-Siberian-Husky-Puppy-HD-Wallpaper.jpg" />
</div>

CSS:

div
{
    width: 200px;
    height: 200px;
    overflow: hidden;
}

div > img
{
    width: 300px;
}

Here's a fiddle.

I would like to make a addon for tiago's answer:

Suppose you're hiding element using ng-show and adding a required attribute on the same:

<div ng-show="false">
    <input required name="something" ng-model="name"/>
</div>

will throw an error something like :

An invalid form control with name='' is not focusable

This is because you just cannot impose required validation on hidden elements. Using ng-required makes it easier to conditionally apply required validation which is just awesome!!

Don't get confused with the concepts of Angular and RxJS

We have pipes concept in Angular and pipe() function in RxJS.

1) Pipes in Angular: A pipe takes in data as input and transforms it to the desired output
https://angular.io/guide/pipes

2) pipe() function in RxJS: You can use pipes to link operators together. Pipes let you combine multiple functions into a single function.

The pipe() function takes as its arguments the functions you want to combine, and returns a new function that, when executed, runs the composed functions in sequence.
https://angular.io/guide/rx-library (search for pipes in this URL, you can find the same)

So according to your question, you are referring pipe() function in RxJS

On a Mac, I found the output contained the information I was looking for:

Just download and install "Samsung Kies" from this link. and everything would work as required.

Before installing, uninstall the drivers you have installed for your device.

Update:

Two possible solutions:

1. Try with the Google USB driver which comes with the SDK.
2. Download and install the Samsung USB driver from this link as suggested by Mauricio Gracia Gutierrez

If you use Integrated Security, you might want to know that you simply need to use -E like this:

sqlcmd -S Serverinstance -E -i import_file.sql

Your syntax is incorrect.

card_value = $(array[i]).val(); or card_value = array[i].value;

array[i] is not a jQuery object (for some reason).

Checking your browser's console can be helpful for things like this.

Just look at the docs:

require_relative complements the builtin method require by allowing you to load a file that is relative to the file containing the require_relative statement.

For example, if you have unit test classes in the "test" directory, and data for them under the test "test/data" directory, then you might use a line like this in a test case:

require_relative "data/customer_data_1"

I would do this:

data["list"].append({'b':'2'})

so simply you are adding an object to the list that is present in "data"

Place your layout in a ScrollView.

You can't declare an array using a variable so Byte byteData[len]; won't work. If you want to copy the data from a pointer, you also need to memcpy (which will go through the data pointed to by the pointer and copy each byte up to a specified length).

Try:

NSData *data = [NSData dataWithContentsOfFile:filePath];
NSUInteger len = [data length];
Byte *byteData = (Byte*)malloc(len);
memcpy(byteData, [data bytes], len);

This code will dynamically allocate the array to the correct size (you must free(byteData) when you're done) and copy the bytes into it.

You could also use getBytes:length: as indicated by others if you want to use a fixed length array. This avoids malloc/free but is less extensible and more prone to buffer overflow issues so I rarely ever use it.

I had given permissions I shouldn't have to write in some folders (especially /usr/bin/), and that caused the problem. I fixed it by opening Disk Utility and running 'Repair Disk Permissions' on the Macintosh HD disk.

I have edited the function for you,

void readFile()
{
    ifstream file;
    file.open ("program.txt");
    if (!file.is_open()) return;

    string word;
    while (file >> word)
    {
        cout<< word << '\n';
    }
}

Differences between isinstance() and type() in Python?

Type-checking with

isinstance(obj, Base)

allows for instances of subclasses and multiple possible bases:

isinstance(obj, (Base1, Base2))

whereas type-checking with

type(obj) is Base

only supports the type referenced.

As a sidenote, is is likely more appropriate than

type(obj) == Base

because classes are singletons.

Avoid type-checking - use Polymorphism (duck-typing)

In Python, usually you want to allow any type for your arguments, treat it as expected, and if the object doesn't behave as expected, it will raise an appropriate error. This is known as polymorphism, also known as duck-typing.

def function_of_duck(duck):
    duck.quack()
    duck.swim()

If the code above works, we can presume our argument is a duck. Thus we can pass in other things are actual sub-types of duck:

function_of_duck(mallard)

or that work like a duck:

function_of_duck(object_that_quacks_and_swims_like_a_duck)

and our code still works.

However, there are some cases where it is desirable to explicitly type-check. Perhaps you have sensible things to do with different object types. For example, the Pandas Dataframe object can be constructed from dicts or records. In such a case, your code needs to know what type of argument it is getting so that it can properly handle it.

So, to answer the question:

Differences between isinstance() and type() in Python?

Allow me to demonstrate the difference:

type

Say you need to ensure a certain behavior if your function gets a certain kind of argument (a common use-case for constructors). If you check for type like this:

def foo(data):
    '''accepts a dict to construct something, string support in future'''
    if type(data) is not dict:
        # we're only going to test for dicts for now
        raise ValueError('only dicts are supported for now')

If we try to pass in a dict that is a subclass of dict (as we should be able to, if we're expecting our code to follow the principle of Liskov Substitution, that subtypes can be substituted for types) our code breaks!:

from collections import OrderedDict

foo(OrderedDict([('foo', 'bar'), ('fizz', 'buzz')]))

raises an error!

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 3, in foo
ValueError: argument must be a dict

isinstance

But if we use isinstance, we can support Liskov Substitution!:

def foo(a_dict):
    if not isinstance(a_dict, dict):
        raise ValueError('argument must be a dict')
    return a_dict

foo(OrderedDict([('foo', 'bar'), ('fizz', 'buzz')]))

returns OrderedDict([('foo', 'bar'), ('fizz', 'buzz')])

Abstract Base Classes

In fact, we can do even better. collections provides Abstract Base Classes that enforce minimal protocols for various types. In our case, if we only expect the Mapping protocol, we can do the following, and our code becomes even more flexible:

from collections import Mapping

def foo(a_dict):
    if not isinstance(a_dict, Mapping):
        raise ValueError('argument must be a dict')
    return a_dict

Response to comment:

It should be noted that type can be used to check against multiple classes using type(obj) in (A, B, C)

Yes, you can test for equality of types, but instead of the above, use the multiple bases for control flow, unless you are specifically only allowing those types:

isinstance(obj, (A, B, C))

The difference, again, is that isinstance supports subclasses that can be substituted for the parent without otherwise breaking the program, a property known as Liskov substitution.

Even better, though, invert your dependencies and don't check for specific types at all.

Conclusion

So since we want to support substituting subclasses, in most cases, we want to avoid type-checking with type and prefer type-checking with isinstance - unless you really need to know the precise class of an instance.

You can install pip (or any other package) with easy_install almost as described in the first answer. However you will need a HTTPS proxy, too. The full sequence of commands is:

set http_proxy=http://proxy.myproxy.com
set https_proxy=http://proxy.myproxy.com
easy_install pip

You might also want to add a port to the proxy, such as http{s}_proxy=http://proxy.myproxy.com:8080

Since PowerShell 6.0, Join-Path has a new parameter called -AdditionalChildPath and can combine multiple parts of a path out-of-the-box. Either by providing the extra parameter or by just supplying a list of elements.

Example from the documentation:

Join-Path a b c d e f g
a\b\c\d\e\f\g

So in PowerShell 6.0 and above your variant

$path = Join-Path C: "Program Files" "Microsoft Office"

works as expected!

Looks like thread is old, I just wanted to add my solution here(Using AspectJ - AOP in spring).

Solution is to create a custom annotation @InjectSequenceValue as follows.

@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.FIELD)
public @interface InjectSequenceValue {
    String sequencename();
}

Now you can annotate any field in entity, so that the underlying field (Long/Integer) value will be injected at runtime using the nextvalue of the sequence.

Annotate like this.

//serialNumber will be injected dynamically, with the next value of the serialnum_sequence.
 @InjectSequenceValue(sequencename = "serialnum_sequence") 
  Long serialNumber;

So far we have marked the field we need to inject the sequence value.So we will look how to inject the sequence value to the marked fields, this is done by creating the point cut in AspectJ.

We will trigger the injection just before the save/persist method is being executed.This is done in the below class.

@Aspect
@Configuration
public class AspectDefinition {

    @Autowired
    JdbcTemplate jdbcTemplate;


    //@Before("execution(* org.hibernate.session.save(..))") Use this for Hibernate.(also include session.save())
    @Before("execution(* org.springframework.data.repository.CrudRepository.save(..))") //This is for JPA.
    public void generateSequence(JoinPoint joinPoint){

        Object [] aragumentList=joinPoint.getArgs(); //Getting all arguments of the save
        for (Object arg :aragumentList ) {
            if (arg.getClass().isAnnotationPresent(Entity.class)){ // getting the Entity class

                Field[] fields = arg.getClass().getDeclaredFields();
                for (Field field : fields) {
                    if (field.isAnnotationPresent(InjectSequenceValue.class)) { //getting annotated fields

                        field.setAccessible(true); 
                        try {
                            if (field.get(arg) == null){ // Setting the next value
                                String sequenceName=field.getAnnotation(InjectSequenceValue.class).sequencename();
                                long nextval=getNextValue(sequenceName);
                                System.out.println("Next value :"+nextval); //TODO remove sout.
                                field.set(arg, nextval);
                            }

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

        }
    }

    /**
     * This method fetches the next value from sequence
     * @param sequence
     * @return
     */

    public long getNextValue(String sequence){
        long sequenceNextVal=0L;

        SqlRowSet sqlRowSet= jdbcTemplate.queryForRowSet("SELECT "+sequence+".NEXTVAL as value FROM DUAL");
        while (sqlRowSet.next()){
            sequenceNextVal=sqlRowSet.getLong("value");

        }
        return  sequenceNextVal;
    }
}

Now you can annotate any Entity as below.

@Entity
@Table(name = "T_USER")
public class UserEntity {

    @Id
    @SequenceGenerator(sequenceName = "userid_sequence",name = "this_seq")
    @GeneratedValue(strategy = GenerationType.SEQUENCE,generator = "this_seq")
    Long id;
    String userName;
    String password;

    @InjectSequenceValue(sequencename = "serialnum_sequence") // this will be injected at the time of saving.
    Long serialNumber;

    String name;
}

Are you looking for...

a if b else c

Or perhaps you misunderstand Python's or? True or True is True.

You should be able to do this like (as you're using the query api):

Entrant.where("pincode").ne(null)

... which will result in a mongo query resembling:

entrants.find({ pincode: { $ne: null } })

A few links that might help:

• The mongoose query api
• The docs for mongo query operators

use this

 SELECT weight INTO @x FROM p_status where tcount=['value'] LIMIT 1;

tested and workes fine...

I implemented translucent Toolbar by creating two Theme.AppCompat.Light.NoActionBar themes and setting colorPrimary attribute to transparent color.

1) Create one theme for opaque Toolbar:

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">

    <!-- Toolbar background color -->
    <item name="colorPrimary">#ff212cff</item>

</style>

Second theme for transparent/overlay Toolbar:

<style name="AppTheme.Overlay" parent="AppTheme">
    <item name="colorPrimary">@color/transparent</item>
</style>

2) In your activity layout, put Toolbar behind content so it can be displayed in front of it:

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <fragment
        android:id="@+id/container"
        android:name="com.test.CustomFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="?attr/colorPrimary"
        android:minHeight="?attr/actionBarSize"
        app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
        app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"/>

</RelativeLayout>

3) Apply the transparent theme to your acivity in AndroidManifest.xml

    <activity
        android:name="com.test.TransparentActivity"
        android:parentActivityName="com.test.HomeActivity"
        android:theme="@style/AppTheme.Overlay" >
        <meta-data
            android:name="android.support.PARENT_ACTIVITY"
            android:value="com.test.HomeActivity" />
    </activity>

Simple two string solution from this answer:

For sh, bash, etc:

# ~/.profile
if ! pgrep -q -U `whoami` -x 'ssh-agent'; then ssh-agent -s > ~/.ssh-agent.sh; fi
. ~/.ssh-agent.sh

For csh, tcsh, etc:

# ~/.schrc
sh -c 'if ! pgrep -q -U `whoami` -x 'ssh-agent'; then ssh-agent -c > ~/.ssh-agent.tcsh; fi'
eval `cat ~/.ssh-agent.tcsh`

There might be another way, but this should work:

SELECT [Title], [Firstname], [Surname], [Company_name], [Interest] 
FROM [dbo].[EXTRANET] 
WHERE day(Submission_date)=day(now) and 
     month(Submission_date)=month(now)
     and year(Submission_date)=year(now)

std::string has a constructor for this:

const char *s = "Hello, World!";
std::string str(s);

Note that this construct deep copies the character list at s and s should not be nullptr, or else behavior is undefined.

Finally, I've defeated my CiSCO EAP-FAST corporate wifi network, and all our Android devices are now able to connect to it.

The walk-around I've performed in order to gain access to this kind of networks from an Android device are easiest than you can imagine.

There's a Wifi Config Editor in the Google Play Store you can use to "activate" the secondary CISCO Protocols when you are setting up a EAP wifi connection.

Its name is Wifi Config Advanced Editor.

• First, you have to setup your wireless network manually as close as you can to your "official" corporate wifi parameters.

• Save it.

• Go to the WCE and edit the parameters of the network you have created in the previous step.

• There are 3 or 4 series of settings you should activate in order to force the Android device to use them as a way to connect (the main site I think you want to visit is Enterprise Configuration, but don't forget to check all the parameters to change them if needed.
  As a suggestion, even if you have a WPA2 EAP-FAST Cipher, try LEAP in your setup. It worked for me as a charm.

• When you finished to edit the config, go to the main Android wifi controller, and force to connect to this network.

• Do not Edit the network again with the Android wifi interface.

I have tested it on Samsung Galaxy 1 and 2, Note mobile devices, and on a Lenovo Thinkpad Tablet.

This doesn't have the regex overhead

double myNum = 0;
String testVar = "Not A Number";

if (Double.TryParse(testVar, out myNum)) {
  // it is a number
} else {
  // it is not a number
}

Incidentally, all of the standard data types, with the glaring exception of GUIDs, support TryParse.

update
secretwep brought up that the value "2345," will pass the above test as a number. However, if you need to ensure that all of the characters within the string are digits, then another approach should be taken.

example 1:

public Boolean IsNumber(String s) {
  Boolean value = true;
  foreach(Char c in s.ToCharArray()) {
    value = value && Char.IsDigit(c);
  }

  return value;
}

or if you want to be a little more fancy

public Boolean IsNumber(String value) {
  return value.All(Char.IsDigit);
}

update 2 ( from @stackonfire to deal with null or empty strings)

public Boolean IsNumber(String s) { 
    Boolean value = true; 
    if (s == String.Empty || s == null) { 
        value=false; 
    } else { 
        foreach(Char c in s.ToCharArray()) { 
            value = value && Char.IsDigit(c); 
        } 
    } return value; 
}

The underscore is the wildcard in a LIKE query for one arbitrary character.

Hence LIKE %_% means "give me all records with at least one arbitrary character in this column".

You have to escape the wildcard character, in sql-server with [] around:

SELECT m.* 
FROM Manager m 
WHERE m.managerid    LIKE  '[_]%'
AND   m.managername  LIKE '%[_]%'

See: LIKE (Transact-SQL)

Demo

I found json_reformat to be very handy. So I just did the following:

curl http://127.0.0.1:5000/people/api.json | json_reformat

that's it!

I have created a realtively small (4.89 KB) javascript library for this exact functionality.

Found on my GitHub here: https://github.com/thelevicole/youtube-to-html5-loader/

It's as simple as:

<video data-yt2html5="https://www.youtube.com/watch?v=ScMzIvxBSi4"></video>

<script src="https://cdn.jsdelivr.net/gh/thelevicole/[email protected]/dist/YouTubeToHtml5.js"></script>
<script>new YouTubeToHtml5();</script>

Working example here: https://jsfiddle.net/thelevicole/5g6dbpx3/1/

What the library does is extract the video ID from the data attribute and makes a request to the https://www.youtube.com/get_video_info?video_id=. It decodes the response which includes streaming information we can use to add a source to the <video> tag.

You have to update your

scanBasePackages = { "com.exm.java" }

to add the path to your service (after annotating it with @service )

Not sure if this is still relevant, but I use this way

Public bEnableEvents As Boolean
Public bclickok As Boolean
Public booRestoreErrorChecking As Boolean   'put this at the top of the module

 Private Declare Function apiGetComputerName Lib "kernel32" Alias _
"GetComputerNameA" (ByVal lpBuffer As String, nSize As Long) As Long
Private Declare Function apiGetUserName Lib "advapi32.dll" Alias _
"GetUserNameA" (ByVal lpBuffer As String, nSize As Long) As Long

Function GetUserID() As String
' Returns the network login name
On Error Resume Next
Dim lngLen As Long, lngX As Long
Dim strUserName As String
strUserName = String$(254, 0)
lngLen = 255
lngX = apiGetUserName(strUserName, lngLen)
If lngX <> 0 Then
    GetUserID = Left$(strUserName, lngLen - 1)
Else
    GetUserID = ""
End If
Exit Function
End Function

This next bit I save file as PDF, but can change to suit

Public Sub SaveToDesktop()
Dim LoginName As String
LoginName = UCase(GetUserID)

ChDir "C:\Users\" & LoginName & "\Desktop\"
Debug.Print LoginName
ActiveSheet.ExportAsFixedFormat Type:=xlTypePDF, Filename:= _
    "C:\Users\" & LoginName & "\Desktop\MyFileName.pdf", Quality:=xlQualityStandard, _
    IncludeDocProperties:=True, IgnorePrintAreas:=False, OpenAfterPublish:= _
    True
End Sub

We've used a solution based on timeGetTime in winmm.dll for millisecond accuracy for many years. See http://www.aboutvb.de/kom/artikel/komstopwatch.htm

The article is in German, but the code in the download (a VBA class wrapping the dll function call) is simple enough to use and understand without being able to read the article.

According to an article on Medium, this will work:

install --upgrade pandas==1.0.0rc0

You simply cannot. DataFrames, same as other distributed data structures, are not iterable and can be accessed using only dedicated higher order function and / or SQL methods.

You can of course collect

for row in df.rdd.collect():
    do_something(row)

or convert toLocalIterator

for row in df.rdd.toLocalIterator():
    do_something(row)

and iterate locally as shown above, but it beats all purpose of using Spark.

To avoid Special Characters in input type

public static InputFilter filter = new InputFilter() {
    @Override
    public CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend) {
        String blockCharacterSet = "~#^|$%*!@/()-'\":;,?{}=!$^';,?×÷<>{}€£¥?%~`¤??_|«»¡¿°•???¦???????????????:-);-):-D:-(:'(:O 1234567890";
        if (source != null && blockCharacterSet.contains(("" + source))) {
            return "";
        }
        return null;
    }
};

You can set filter to your edit text like below

edtText.setFilters(new InputFilter[] { filter });

By combining Sanjeevakumar Hiremath's and Jeff Mercado's answers you can actually in a way get around the problem when retrieving the icon from a 64-bit process in a 32-bit process.

using System;
using System.Management;
using System.Diagnostics;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            int processID = 6680;   // Change for the process you would like to use
            Process process = Process.GetProcessById(processID);
            string path = ProcessExecutablePath(process);
        }

        static private string ProcessExecutablePath(Process process)
        {
            try
            {
                return process.MainModule.FileName;
            }
            catch
            {
                string query = "SELECT ExecutablePath, ProcessID FROM Win32_Process";
                ManagementObjectSearcher searcher = new ManagementObjectSearcher(query);

                foreach (ManagementObject item in searcher.Get())
                {
                    object id = item["ProcessID"];
                    object path = item["ExecutablePath"];

                    if (path != null && id.ToString() == process.Id.ToString())
                    {
                        return path.ToString();
                    }
                }
            }

            return "";
        }
    }
}

This may be a bit slow and doesn't work on every process which lacks a "valid" icon.

You need to use the jQuery AJAX or XMLHttpRequest() for post the data to the server. After data posting you can redirect your page to another page by window.location.href.

Example:

 var xhttp = new XMLHttpRequest();
  xhttp.onreadystatechange = function() {
    if (this.readyState == 4 && this.status == 200) {
      window.location.href = 'https://website.com/my-account';
    }
  };
  xhttp.open("POST", "demo_post.asp", true);
  xhttp.send();

Func - When you want a delegate for a function that may or may not take parameters and returns a value. The most common example would be Select from LINQ:

var result = someCollection.Select( x => new { x.Name, x.Address });

Action - When you want a delegate for a function that may or may not take parameters and does not return a value. I use these often for anonymous event handlers:

button1.Click += (sender, e) => { /* Do Some Work */ }

Predicate - When you want a specialized version of a Func that evaluates a value against a set of criteria and returns a boolean result (true for a match, false otherwise). Again, these are used in LINQ quite frequently for things like Where:

var filteredResults = 
    someCollection.Where(x => x.someCriteriaHolder == someCriteria);

I just double checked and it turns out that LINQ doesn't use Predicates. Not sure why they made that decision...but theoretically it is still a situation where a Predicate would fit.

This is all i can find out. Not sure if it helps, but thought I'd add it to the mix.

WORD-WRAP

This property specifies whether the current rendered line should break if the content exceeds the boundary of the specified rendering box for an element (this is similar in some ways to the ‘clip’ and ‘overflow’ properties in intent.) This property should only apply if the element has a visual rendering, is an inline element with explicit height/width, is absolutely positioned and/or is a block element.

WORD-BREAK

This property controls the line breaking behavior within words. It is especially useful in cases where multiple languages are used within an element.

this will help all of you to find your own correct details use

npm ls dist-tag

this will then show the correct info so you don't guess the version file location etc

enjoy :)

There is another way to solve this, using a map:

vector<double> v = {...}; // input data
map<double, unsigned> m; // mapping from value to its index
for (auto it = v.begin(); it != v.end(); ++it)
    m[*it] = it - v.begin();

This will eradicate non-unique elements though. If that's not acceptable, use a multimap:

vector<double> v = {...}; // input data
multimap<double, unsigned> m; // mapping from value to its index
for (auto it = v.begin(); it != v.end(); ++it)
    m.insert(make_pair(*it, it - v.begin()));

In order to output the indices, iterate over the map or multimap:

for (auto it = m.begin(); it != m.end(); ++it)
    cout << it->second << endl;

I had a similar issue in Azure Data Factory with the : character.

I resolved the problem by substituting : with %3A

as shown here.

For example, I substituted

date1=2020-01-25T00:00:00.000Z

with

date1=2020-01-25T00%3A00%3A00.000Z

You need an INSERT ... SELECT

INSERT INTO exception_codes( code, message )
  SELECT code, message
    FROM exception_code_tmp

How does the virtual keyword work?

Assume that Man is a base class, Indian is derived from man.

Class Man
{
 public: 
   virtual void do_work()
   {}
}

Class Indian : public Man
{
 public: 
   void do_work()
   {}
}

Declaring do_work() as virtual simply means: which do_work() to call will be determined ONLY at run-time.

Suppose I do,

Man *man;
man = new Indian();
man->do_work(); // Indian's do work is only called.

If virtual is not used, the same is statically determined or statically bound by the compiler, depending on what object is calling. So if an object of Man calls do_work(), Man's do_work() is called EVEN THOUGH IT POINTS TO AN INDIAN OBJECT

I believe that the top voted answer is misleading - Any method whether or not virtual can have an overridden implementation in the derived class. With specific reference to C++ the correct difference is run-time (when virtual is used) binding and compile-time (when virtual is not used but a method is overridden and a base pointer is pointed at a derived object) binding of associated functions.

There seems to be another misleading comment that says,

"Justin, 'pure virtual' is just a term (not a keyword, see my answer below) used to mean "this function cannot be implemented by the base class."

THIS IS WRONG! Purely virtual functions can also have a body AND CAN BE IMPLEMENTED! The truth is that an abstract class' pure virtual function can be called statically! Two very good authors are Bjarne Stroustrup and Stan Lippman.... because they wrote the language.

Simpler than ever, forget about ViewTypes. Is not recommended to use multiple viewtypes inside one adapter, it will mess the code and break the single responsibility principle since now the adapter needs to handle logic to know which view to inflate, now imagine working in large teams where each team has to work in one of those viewtypes features, it will be a mess to touch the same adapter by all the teams that work in the different viewtypes, this is solved using ConcatAdapter where you isolate the adapters, code them one by one and then just merge them inside one view.

From recyclerview:1.2.0-alpha04 you now can use ConcatAdapter

If you need a view with different viewTypes , you can just write the Adapters for each section and just use ConcatAdapter to merge all of them inside one recyclerview

ConcatAdapter

This image shows 3 different viewtypes that one recyclerview has, header, content and footer.

You only create one adapter for each section, and then just use ConcatAdapter to merge them inside one recyclerview

val firstAdapter: FirstAdapter = …
val secondAdapter: SecondAdapter = …
val thirdAdapter: ThirdAdapter = …
val concatAdapter = ConcatAdapter(firstAdapter, secondAdapter, 
     thirdAdapter)
recyclerView.adapter = concatAdapter

Thats all you need to know, if you want to handle loading state, for example remove the last adapter after some loading happened, you can use LoadState

Abramov's goal - and everyone's ideally - is simply to encapsulate complexity (and async calls) in the place where it's most appropriate.

Where's the best place to do that in the standard Redux dataflow? How about:

• Reducers? No way. They should be pure functions with no side-effects. Updating the store is serious, complicated business. Don't contaminate it.
• Dumb View Components? Definitely No. They have one concern: presentation and user-interaction, and should be as simple as possible.
• Container Components? Possible, but sub-optimal. It makes sense in that the container is a place where we encapsulate some view related complexity and interact with the store, but:
  • Containers do need to be more complex than dumb components, but it's still a single responsibility: providing bindings between view and state/store. Your async logic is a whole separate concern from that.
  • By placing it in a container, you'd be locking your async logic into a single context, for a single view/route. Bad idea. Ideally it's all reusable, and totally decoupled.
• Some other Service Module? Bad idea: you'd need to inject access to the store, which is a maintainability/testability nightmare. Better to go with the grain of Redux and access the store only using the APIs/models provided.
• Actions and the Middlewares that interpret them? Why not?! For starters, it's the only major option we have left. :-) More logically, the action system is decoupled execution logic that you can use from anywhere. It's got access to the store and can dispatch more actions. It has a single responsibility which is to organize the flow of control and data around the application, and most async fits right into that.
  • What about the Action Creators? Why not just do async in there, instead of in the actions themselves, and in Middleware?
    • First and most important, the creators don't have access to the store, as middleware does. That means you can't dispatch new contingent actions, can't read from the store to compose your async, etc.
    • So, keep complexity in a place that's complex of necessity, and keep everything else simple. The creators can then be simple, relatively pure functions that are easy to test.

In the iframe: So that means you have to add some code in the iframe page. Simply add this script to your code IN THE IFRAME:

<body onload="parent.alertsize(document.body.scrollHeight);">

In the holding page: In the page holding the iframe (in my case with ID="myiframe") add a small javascript:

<script>
function alertsize(pixels){
    pixels+=32;
    document.getElementById('myiframe').style.height=pixels+"px";
}
</script>

What happens now is that when the iframe is loaded it triggers a javascript in the parent window, which in this case is the page holding the iframe.

To that JavaScript function it sends how many pixels its (iframe) height is.

The parent window takes the number, adds 32 to it to avoid scrollbars, and sets the iframe height to the new number.

That's it, nothing else is needed.

But if you like to know some more small tricks keep on reading...

DYNAMIC HEIGHT IN THE IFRAME? If you like me like to toggle content the iframe height will change (without the page reloading and triggering the onload). I usually add a very simple toggle script I found online:

<script>
function toggle(obj) {
    var el = document.getElementById(obj);
    if ( el.style.display != 'block' ) el.style.display = 'block';
    else el.style.display = 'none';
}
</script>

to that script just add:

<script>
function toggle(obj) {
    var el = document.getElementById(obj);
    if ( el.style.display != 'block' ) el.style.display = 'block';
    else el.style.display = 'none';
    parent.alertsize(document.body.scrollHeight); // ADD THIS LINE!
}
</script>

How you use the above script is easy:

<a href="javascript:toggle('moreheight')">toggle height?</a><br />
<div style="display:none;" id="moreheight">
more height!<br />
more height!<br />
more height!<br />
</div>

For those that like to just cut and paste and go from there here is the two pages. In my case I had them in the same folder, but it should work cross domain too (I think...)

Demo

select a.* , b.Aa , b.Ab, b.Ac from table1 a left join table2 b on a.id=b.id

this should select all columns from table 1 and only the listed columns from table 2 joined by id.

"Any" works well. Just make sure that the any keyword is on the right side of the equal to sign i.e. is present after the equal to sign.

Below statement will throw error: ERROR: syntax error at or near "any"

select 1 where any('{hello}'::text[]) = 'hello';

Whereas below example works fine

select 1 where 'hello' = any('{hello}'::text[]);

Here is perhaps the simplest way to obtain the value of a single cell.

document.querySelector("#table").children[0].children[r].children[c].innerText

where r is the row index and c is the column index

Therefore, to obtain all cell data and put it in a multi-dimensional array:

var tableData = [];  
Array.from(document.querySelector("#table").children[0].children).forEach(function(tr){tableData.push(Array.from(tr.children).map(cell => cell.innerText))}); 
var cell = tableData[1][2];//2nd row, 3rd column

To access a specific cell's data in this multi-dimensional array, use the standard syntax: array[rowIndex][columnIndex].

You should use Android NDK to develop performance-critical portions of your apps in native code. See Android NDK.

Anyway i don't think it is the right way to develop an entire application.

Try using OPENDATASOURCE The syntax is like this:

select * from OPENDATASOURCE ('SQLNCLI', 'Data Source=192.168.6.69;Initial Catalog=AnotherDatabase;Persist Security Info=True;User ID=sa;Password=AnotherDBPassword;MultipleActiveResultSets=true;' ).HumanResources.Department.MyTable    

Adding on to the top answer you can also use views with a dark gray background color in a Linear Layout like so.

<View
    android:layout_width="match_parent"
    android:layout_height="1dip"
    android:layout_marginBottom="4dip"
    android:layout_marginLeft="4dip"
    android:layout_marginRight="4dip"
    android:layout_marginTop="4dip"
    android:background="@android:color/darker_gray"/>

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginBottom="4dip"
    android:orientation="horizontal"
    android:weightSum="1">

    <Button
        android:id="@+id/button_decline"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="10dp"
        android:layout_weight="0.50"
        android:background="?android:attr/selectableItemBackground"
        android:padding="10dip"
        android:text="@string/decline"/>

    <View
        android:layout_width="1dip"
        android:layout_height="match_parent"
        android:layout_marginLeft="4dip"
        android:layout_marginRight="4dip"
        android:background="@android:color/darker_gray"/>

    <Button
        android:id="@+id/button_accept"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginRight="10dp"
        android:layout_weight="0.50"
        android:background="?android:attr/selectableItemBackground"
        android:padding="10dip"
        android:text="@string/accept"/>
</LinearLayout>

If your line is horizontal you'll want to set the height to 1dip and the width to match the parent and vice-versa if your line is vertical.

This works nicely on macOS too:

ruby -e "Dir['*'].each { |p| File.rename(p, p.downcase) }"

User interactive approach:

git clean -i -fd

Remove .classpath [y/N]? N
Remove .gitignore [y/N]? N
Remove .project [y/N]? N
Remove .settings/ [y/N]? N
Remove src/com/amazon/arsdumpgenerator/inspector/ [y/N]? y
Remove src/com/amazon/arsdumpgenerator/manifest/ [y/N]? y
Remove src/com/amazon/arsdumpgenerator/s3/ [y/N]? y
Remove tst/com/amazon/arsdumpgenerator/manifest/ [y/N]? y
Remove tst/com/amazon/arsdumpgenerator/s3/ [y/N]? y

-i for interactive
-f for force
-d for directory
-x for ignored files(add if required)

Note: Add -n or --dry-run to just check what it will do.

This answer goes over the exact same thing (although for angular) -- it is a CORS issue.

One quick fix is to modify each POST request by specifying one of the 'Content-Type' header values which will not trigger a "preflight". These types are:

• application/x-www-form-urlencoded
• multipart/form-data
• text/plain

ANYTHING ELSE triggers a preflight.

For example:

$.ajax({
   url: 'http://api.example.com/users/get',
   type: 'POST',
   headers: {
      'name-api-key':'ewf45r4435trge',
      'Content-Type':'application/x-www-form-urlencoded'
   },
   data: {
      'uid':36,
   },
   success: function(data) {
      console.log(data);
   }
});

create an int array and a list

from array import array
listA = list(range(0,50))
for item in listA:
    print(item)
arrayA = array("i", listA)
for item in arrayA:
    print(item)

If you use numpy, this is easy:

slice = arr[:2,:2]

or if you want the 0's,

slice = arr[0:2,0:2]

You'll get the same result.

*note that slice is actually the name of a builtin-type. Generally, I would advise giving your object a different "name".

Another way, if you're working with lists of lists*:

slice = [arr[i][0:2] for i in range(0,2)]

(Note that the 0's here are unnecessary: [arr[i][:2] for i in range(2)] would also work.).

What I did here is that I take each desired row 1 at a time (arr[i]). I then slice the columns I want out of that row and add it to the list that I'm building.

If you naively try: arr[0:2] You get the first 2 rows which if you then slice again arr[0:2][0:2], you're just slicing the first two rows over again.

*This actually works for numpy arrays too, but it will be slow compared to the "native" solution I posted above.

very good explanation on this post.

http://useyourloaf.com/blog/2010/10/02/dynamically-loading-new-rows-into-a-table.html

simple you have to add last row and hide it and when table row hit last row than show the row and load more items.

You can also use /dev/urandom:

grep -m1 -ao '[0-9]' /dev/urandom | sed s/0/10/ | head -n1

Have you checked this http://support.microsoft.com/kb/209805? In particular, whether you have Msrd3x40.dll.

You may also like to check that you have the latest version of Jet: http://support.microsoft.com/kb/239114

Actually you need two div's for vertical centering. The div containing the content must have a width and height.

#container {_x000D_
  position: absolute;_x000D_
  top: 50%;_x000D_
  margin-top: -200px;_x000D_
  /* half of #content height*/_x000D_
  left: 0;_x000D_
  width: 100%;_x000D_
}_x000D_
_x000D_
#content {_x000D_
  width: 624px;_x000D_
  margin-left: auto;_x000D_
  margin-right: auto;_x000D_
  height: 395px;_x000D_
  border: 1px solid #000000;_x000D_
}

<div id="container">_x000D_
  <div id="content">_x000D_
    <h1>Centered div</h1>_x000D_
  </div>_x000D_
</div>

Here is the result

You have to add an OnItemClickListener to the listview to determine which item was clicked, then find the checkbox.

mListView.setOnItemClickListener(new OnItemClickListener()
{
    @Override
    public void onItemClick(AdapterView<?> parent, View v, int position, long id)
    {
        CheckBox cb = (CheckBox) v.findViewById(R.id.checkbox_id);
    }
});

You must add your keyListener to every component that you need. Only the component with the focus will send these events. For instance, if you have only one TextBox in your JFrame, that TextBox has the focus. So you must add a KeyListener to this component as well.

The process is the same:

myComponent.addKeyListener(new KeyListener ...);

Note: Some components aren't focusable like JLabel.

For setting them to focusable you need to:

myComponent.setFocusable(true);

You might want to use one of the existing open source Finite State Machines. E.g. bbv.Common.StateMachine found at http://code.google.com/p/bbvcommon/wiki/StateMachine. It has a very intuitive fluent syntax and a lot of features such as, enter/exit actions, transition actions, guards, hierarchical, passive implementation (executed on the thread of the caller) and active implementation (own thread on which the fsm runs, events are added to a queue).

Taking Juliets example the definition for the state machine gets very easy:

var fsm = new PassiveStateMachine<ProcessState, Command>();
fsm.In(ProcessState.Inactive)
   .On(Command.Exit).Goto(ProcessState.Terminated).Execute(SomeTransitionAction)
   .On(Command.Begin).Goto(ProcessState.Active);
fsm.In(ProcessState.Active)
   .ExecuteOnEntry(SomeEntryAction)
   .ExecuteOnExit(SomeExitAction)
   .On(Command.End).Goto(ProcessState.Inactive)
   .On(Command.Pause).Goto(ProcessState.Paused);
fsm.In(ProcessState.Paused)
   .On(Command.End).Goto(ProcessState.Inactive).OnlyIf(SomeGuard)
   .On(Command.Resume).Goto(ProcessState.Active);
fsm.Initialize(ProcessState.Inactive);
fsm.Start();

fsm.Fire(Command.Begin);

Update: The project location has moved to: https://github.com/appccelerate/statemachine

you can try to get it in a lot of ways :

1.Using media="bogus" and a <link> at the foot

<head>
    <!-- unimportant nonsense -->
    <link rel="stylesheet" href="style.css" media="bogus">
</head>
<body>
    <!-- other unimportant nonsense, such as content -->
    <link rel="stylesheet" href="style.css">
</body>

2.Inserting DOM in the old way

<script type="text/javascript">
(function(){
  var bsa = document.createElement('script');
     bsa.type = 'text/javascript';
     bsa.async = true;
     bsa.src = 'https://s3.buysellads.com/ac/bsa.js';
  (document.getElementsByTagName('head')[0]||document.getElementsByTagName('body')[0]).appendChild(bsa);
})();
</script>

3.if you can try plugins you could try loadCSS

<script>
  // include loadCSS here...
  function loadCSS( href, before, media ){ ... }
  // load a file
  loadCSS( "path/to/mystylesheet.css" );
</script>

I'm lately here. But somethings I just known that might help you a bit.

If you are using Java, there is nothing much to change. But for kotlin developers, here is some following snippet I think that can make you a basement to run on:

• Parent fragment:

inline fun <reified T : SampleFragment> newInstance(text: String): T {
    return T::class.java.newInstance().apply {
        arguments = Bundle().also { it.putString("key_text_arg", text) }
    }
}

• Normal call

val f: SampleFragment = SampleFragment.newInstance("ABC")
// or val f = SampleFragment.newInstance<SampleFragment>("ABC")

• You can extend the parent init operation in child fragment class by:

fun newInstance(): ChildSampleFragment {
    val child = UserProfileFragment.newInstance<ChildSampleFragment>("XYZ")
    // Do anything with the current initialized args bundle here
    // with child.arguments = ....
    return child
}

Happy coding.

Replacing substrings should not be that hard.

std::string ReplaceString(std::string subject, const std::string& search,
                          const std::string& replace) {
    size_t pos = 0;
    while((pos = subject.find(search, pos)) != std::string::npos) {
         subject.replace(pos, search.length(), replace);
         pos += replace.length();
    }
    return subject;
}

If you need performance, here is an optimized function that modifies the input string, it does not create a copy of the string:

void ReplaceStringInPlace(std::string& subject, const std::string& search,
                          const std::string& replace) {
    size_t pos = 0;
    while((pos = subject.find(search, pos)) != std::string::npos) {
         subject.replace(pos, search.length(), replace);
         pos += replace.length();
    }
}

Tests:

std::string input = "abc abc def";
std::cout << "Input string: " << input << std::endl;

std::cout << "ReplaceString() return value: " 
          << ReplaceString(input, "bc", "!!") << std::endl;
std::cout << "ReplaceString() input string not changed: " 
          << input << std::endl;

ReplaceStringInPlace(input, "bc", "??");
std::cout << "ReplaceStringInPlace() input string modified: " 
          << input << std::endl;

Output:

Input string: abc abc def
ReplaceString() return value: a!! a!! def
ReplaceString() input string not modified: abc abc def
ReplaceStringInPlace() input string modified: a?? a?? def

.class is used when there isn't an instance of the class available.

.getClass() is used when there is an instance of the class available.

object.getClass() returns the class of the given object.

For example:

String string = "hello";
System.out.println(string.getClass().toString());

This will output:

class java.lang.String

This is the class of the string object :)

Here's a heavy-weight solution that gets you indenting, plus all the HTML pretty-printing you don't necessarily want to care about while you're editing.

First, download Tidy. Make sure you add the binary to your path, so you can call it from any location.

Next, create a config file describing your favorite HTML flavor. Documentation is not great for Tidy, but here's an overview, and a list of all the options. Here's my config file:

bare: yes
break-before-br: no
clean: yes
drop-proprietary-attributes: yes
fix-uri: yes
indent-spaces: 4
indent: yes
logical-emphasis: yes
markup: yes
output-xhtml: yes
quiet: yes
quote-marks: yes
replace-color: yes
tab-size: 4
uppercase-tags: no
vertical-space: yes
word-2000: yes
wrap: 0

Save this as tidyrc_html.txt in your ftplugin folder (under vimfiles).

One more file: add the following line to (or create) html.vim, also in ftplugin:

map <leader>tidy :%! tidy -config ~/vimfiles/ftplugin/tidyrc_html.txt <CR>

To use it, just open an HTML file, and type /tidy. (That / is the <leader> key.)

There you go! Not a quick solution, by any means, but now you're a bit better equipped for editing those huge, messed-up HTML files.

If we have two input fields then get the values from input fields, and then add them using JavaScript.

$('input[name="yourname"]').keyup(function(event) {
    /* Act on the event */
    var value1 = $(this).val();
    var value2 = $('input[name="secondName"]').val();
    var roundofa = +value2+ +value1;

    $('input[name="total"]').val(addition);
});

However, you should also read Elias Mårtenson's answer on Android plurals treatment of “zero”. There is a problem with the interpretation of certain values such as "zero".

It turns out you can also use pow(). For example, you can use the following to express 10 to the 9th.

pow(10, 9)

Along with pow, powf() returns a float instead of a double. I have only tested this on Swift 4 and macOS 10.13.

Using basename I used the following to achieve this:

for file in *; do
    ext=${file##*.}
    fname=`basename $file $ext`

    # Do things with $fname
done;

This requires no a priori knowledge of the file extension and works even when you have a filename that has dots in it's filename (in front of it's extension); it does require the program basename though, but this is part of the GNU coreutils so it should ship with any distro.

There is a pairwise() function example in the itertools document:

from itertools import tee, izip
def pairwise(iterable):
    "s -> (s0,s1), (s1,s2), (s2, s3), ..."
    a, b = tee(iterable)
    next(b, None)
    return izip(a, b)

import pandas as pd
df = pd.DataFrame(['AA', 'BB', 'CC'], columns = ['value'])

for (i1, row1), (i2, row2) in pairwise(df.iterrows()):
    print i1, i2, row1["value"], row2["value"]

Here is the output:

0 1 AA BB
1 2 BB CC

But, I think iter rows in a DataFrame is slow, if you can explain what's the problem you want to solve, maybe I can suggest some better method.

NOTE: If you are working with an HTML5 browser then you should ignore this answer. This is now possible as can be seen in the other answers.

There is no way to modify the URL in the browser without reloading the page. The URL represents what the last loaded page was. If you change it (document.location) then it will reload the page.

One obvious reason being, you write a site on www.mysite.com that looks like a bank login page. Then you change the browser URL bar to say www.mybank.com. The user will be totally unaware that they are really looking at www.mysite.com.

Either the parameter supplied for ZIP_CODE is larger (in length) than ZIP_CODEs column width or the parameter supplied for CITY is larger (in length) than CITYs column width.

It would be interesting to know the values supplied for the two ? placeholders.

I agree with above answers, Here is a complete read and write sample for anyone who needs it.

     router.post('/', function(req, res, next) {

        console.log(req.body);

        var tital = req.body.title;
        var description = req.body.description;

we developed a module on GitHub that has hooks for fetching data so you can use it like this for your purpose:

import { useFetching } from "react-concurrent";

const app = () => {
  const { data, isLoading, error , refetch } = useFetching(() =>
    fetch("http://example.com"),
  );
};

You can fork that out, but any PRs are welcome. https://github.com/hosseinmd/react-concurrent#react-concurrent

List is the preferred way in java 1.5 and beyond as it can use generics. Arrays cannot have generics. Also Arrays have a pre defined length, which cannot grow dynamically. Initializing an array with a large size is not a good idea. ArrayList is the the way to declare an array with generics and it can dynamically grow. But if delete and insert is used more frequently, then linked list is the fastest data structure to be used.

Another simple but effective method is to use split + join repeatedly.

"a=b,c:d".split('=').join(',').split(':').join(',').split(',')

Essentially doing a split followed by a join is like a global replace so this replaces each separator with a comma then once all are replaced it does a final split on comma

The result of the above expression is:

['a', 'b', 'c', 'd']

Expanding on this you could also place it in a function:

function splitMulti(str, tokens){
        var tempChar = tokens[0]; // We can use the first token as a temporary join character
        for(var i = 1; i < tokens.length; i++){
            str = str.split(tokens[i]).join(tempChar);
        }
        str = str.split(tempChar);
        return str;
}

Usage:

splitMulti('a=b,c:d', ['=', ',', ':']) // ["a", "b", "c", "d"]

If you use this functionality a lot it might even be worth considering wrapping String.prototype.split for convenience (I think my function is fairly safe - the only consideration is the additional overhead of the conditionals (minor) and the fact that it lacks an implementation of the limit argument if an array is passed).

Be sure to include the splitMulti function if using this approach to the below simply wraps it :). Also worth noting that some people frown on extending built-ins (as many people do it wrong and conflicts can occur) so if in doubt speak to someone more senior before using this or ask on SO :)

    var splitOrig = String.prototype.split; // Maintain a reference to inbuilt fn
    String.prototype.split = function (){
        if(arguments[0].length > 0){
            if(Object.prototype.toString.call(arguments[0]) == "[object Array]" ) { // Check if our separator is an array
                return splitMulti(this, arguments[0]);  // Call splitMulti
            }
        }
        return splitOrig.apply(this, arguments); // Call original split maintaining context
    };

Usage:

var a = "a=b,c:d";
    a.split(['=', ',', ':']); // ["a", "b", "c", "d"]

// Test to check that the built-in split still works (although our wrapper wouldn't work if it didn't as it depends on it :P)
        a.split('='); // ["a", "b,c:d"] 

Enjoy!

I had the same problem: Singleton or make a subclass android.os.Application?

First I tried with the Singleton but my app at some point makes a call to the browser

Intent myIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.google.com"));

and the problem is that, if the handset doesn't have enough memory, most of your classes (even Singletons) are cleaned to get some memory so, when returning from the browser to my app, it crashed everytime.

Solution: put needed data inside a subclass of Application class.

You can also use parseReactHTMLComponent from Jumper Package. Just look at it, it's easy and you don't need to use JSX syntax.

If anyone actually knew a general and always-applicable answer, it would have been implemented everywhere ages ago and would make our lives SO much easier.

There are many things you can do, but every single one of them has a problem:

1. As Ashwin Prabhu said, if you know the script well, you can observe its behaviour and track some of its variables on window or document etc. This solution, however, is not for everyone and can be used only by you and only on a limited set of pages.

2. Your solution by observing the HTML code and whether it has or hasn't been changed for some time is not bad (also, there is a method to get the original and not-edited HTML directly by WebDriver), but:

   • It takes a long time to actually assert a page and could prolong the test significantly.
   • You never know what the right interval is. The script might be downloading something big that takes more than 500 ms. There are several scripts on our company's internal page that take several seconds in IE. Your computer may be temporarily short on resources - say that an antivirus will make your CPU work fully, then 500 ms may be too short even for a noncomplex scripts.
   • Some scripts are never done. They call themselves with some delay (setTimeout()) and work again and again and could possibly change the HTML every time they run. Seriously, every "Web 2.0" page does it. Even Stack Overflow. You could overwrite the most common methods used and consider the scripts that use them as completed, but ... you can't be sure.
   • What if the script does something other than changing the HTML? It could do thousands of things, not just some innerHTML fun.

3. There are tools to help you on this. Namely Progress Listeners together with nsIWebProgressListener and some others. The browser support for this, however, is horrible. Firefox began to try to support it from FF4 onwards (still evolving), IE has basic support in IE9.

And I guess I could come up with another flawed solution soon. The fact is - there's no definite answer on when to say "now the page is complete" because of the everlasting scripts doing their work. Pick the one that serves you best, but beware of its shortcomings.

Yes, you can have it on multiple lines using the white-space css property :)

input[type="submit"] {_x000D_
    white-space: normal;_x000D_
    width: 100px;_x000D_
}

<input type="submit" value="Some long text that won't fit." />

add this to your element

 white-space: normal;
 width: 100px;

In my case the database was restored and it already had the user used for the connection. I had to drop the user in the database and recreate the user-mapping for the login.

1. Drop the user

   DROP USER [MyUser]
   

It might fail if the user owns any schemas. Those has to assigned to dbo before dropping the user. Get the schemas owned by the user using first query below and then alter the owner of those schemas using second query (HangFire is the schema obtained from previous query).

select * from information_schema.schemata where schema_owner = 'MyUser'
ALTER AUTHORIZATION ON SCHEMA::[HangFire] TO [dbo]     

2. Update user mapping for the user. In management studio go to Security-> Login -> Open the user -> Go to user mapping tab -> Enable the database and grant appropriate role.

Definition:

public static string ConvertByteToString(this byte[] source)
{
    return source != null ? System.Text.Encoding.UTF8.GetString(source) : null;
}

Using:

string result = input.ConvertByteToString();

DataTable.Clone() should do the trick.

DataTable newTable = originalTable.Clone();

If you are able to read the excel file correctly and only the integer values are not showing up. you can specify like this.

df = pd.read_excel('my.xlsx',sheetname='Sheet1', engine="openpyxl", dtype=str)

this should change your integer values into a string and show in dataframe

As you already hinted in your question, your code creates all promises synchronously. Instead they should only be created at the time the preceding one resolves.

Secondly, each promise that is created with new Promise needs to be resolved with a call to resolve (or reject). This should be done when the timer expires. That will trigger any then callback you would have on that promise. And such a then callback (or await) is a necessity in order to implement the chain.

With those ingredients, there are several ways to perform this asynchronous chaining:

1. With a for loop that starts with an immediately resolving promise

2. With Array#reduce that starts with an immediately resolving promise

3. With a function that passes itself as resolution callback

4. With ECMAScript2017's async / await syntax

5. With ECMAScript2020's for await...of syntax

See a snippet and comments for each of these options below.

1. With for

You can use a for loop, but you must make sure it doesn't execute new Promise synchronously. Instead you create an initial immediately resolving promise, and then chain new promises as the previous ones resolve:

for (let i = 0, p = Promise.resolve(); i < 10; i++) {
    p = p.then(_ => new Promise(resolve =>
        setTimeout(function () {
            console.log(i);
            resolve();
        }, Math.random() * 1000)
    ));
}

2. With reduce

This is just a more functional approach to the previous strategy. You create an array with the same length as the chain you want to execute, and start out with an immediately resolving promise:

[...Array(10)].reduce( (p, _, i) => 
    p.then(_ => new Promise(resolve =>
        setTimeout(function () {
            console.log(i);
            resolve();
        }, Math.random() * 1000)
    ))
, Promise.resolve() );

This is probably more useful when you actually have an array with data to be used in the promises.

3. With a function passing itself as resolution-callback

Here we create a function and call it immediately. It creates the first promise synchronously. When it resolves, the function is called again:

(function loop(i) {
    if (i < 10) new Promise((resolve, reject) => {
        setTimeout( () => {
            console.log(i);
            resolve();
        }, Math.random() * 1000);
    }).then(loop.bind(null, i+1));
})(0);

This creates a function named loop, and at the very end of the code you can see it gets called immediately with argument 0. This is the counter, and the i argument. The function will create a new promise if that counter is still below 10, otherwise the chaining stops.

The call to resolve() will trigger the then callback which will call the function again. loop.bind(null, i+1) is just a different way of saying _ => loop(i+1).

4. With async/await

Modern JS engines support this syntax:

(async function loop() {
    for (let i = 0; i < 10; i++) {
        await new Promise(resolve => setTimeout(resolve, Math.random() * 1000));
        console.log(i);
    }
})();

It may look strange, as it seems like the new Promise() calls are executed synchronously, but in reality the async function returns when it executes the first await. Every time an awaited promise resolves, the function's running context is restored, and proceeds after the await, until it encounters the next one, and so it continues until the loop finishes.

As it may be a common thing to return a promise based on a timeout, you could create a separate function for generating such a promise. This is called promisifying a function, in this case setTimeout. It may improve the readability of the code:

const delay = ms => new Promise(resolve => setTimeout(resolve, ms));

(async function loop() {
    for (let i = 0; i < 10; i++) {
        await delay(Math.random() * 1000);
        console.log(i);
    }
})();

5. With for await...of

With EcmaScript 2020, the for await...of found its way to modern JavaScript engines. Although it does not really reduce code in this case, it allows to isolate the definition of the random interval chain from the actual iteration of it:

const delay = ms => new Promise(resolve => setTimeout(resolve, ms));
async function * randomDelays(count ,max) {
    for (let i = 0; i < count; i++) yield delay(Math.random() * max).then(() => i);
}

(async function loop() {
    for await (let i of randomDelays(10, 1000)) console.log(i);
})();

If your goal is only to take the files and not the folder, the approach I made was to use the file size as a filter. This property is the current size of the file hosted by AWS. All the folders return 0 in that property. The following is a C# code using linq but it shouldn't be hard to translate to Java.

var amazonClient = new AmazonS3Client(key, secretKey, region);
var listObjectsRequest= new ListObjectsRequest
            {
                BucketName = 'someBucketName',
                Delimiter = 'someDelimiter',
                Prefix = 'somePrefix'
            };
var objects = amazonClient.ListObjects(listObjectsRequest);
var objectsInFolder = objects.S3Objects.Where(file => file.Size > 0).ToList();

Here is a slightly simpler version that I found. It reads the entire file in one go and only requires a single using directive.

byte[] ComputeHash(string filePath)
{
    using (var md5 = MD5.Create())
    {
        return md5.ComputeHash(File.ReadAllBytes(filePath));
    }
}

You should use better authentication with open keys. In these case you need no password and no expect.

If you want it with expect, use this script (see answer Automate scp file transfer using a shell script ):

#!/usr/bin/expect -f

# connect via scp
    spawn scp "[email protected]:/home/santhosh/file.dmp" /u01/dumps/file.dmp
#######################
expect {
-re ".*es.*o.*" {
    exp_send "yes\r"
    exp_continue
}
-re ".*sword.*" {
    exp_send "PASSWORD\r"
}
}
interact

Also, you can use pexpect (python module):

def doScp(user,password, host, path, files):
 fNames = ' '.join(files)
 print fNames
 child = pexpect.spawn('scp %s %s@%s:%s' % (fNames, user, host,path))
 print 'scp %s %s@%s:%s' % (fNames, user, host,path)
    i = child.expect(['assword:', r"yes/no"], timeout=30)
    if i == 0:
        child.sendline(password)
    elif i == 1:
        child.sendline("yes")
        child.expect("assword:", timeout=30)
        child.sendline(password)
    data = child.read()
    print data
    child.close()

Hey now you can give to body background image

and set the background-position:center center;

as like this

body{
background:url('../img/some.jpg') no-repeat center center;
min-height:100%;
}

The very same. A C string is nothing but an array of characters, so a pointer to a string is a pointer to an array of characters. And a pointer to an array is the very same as a pointer to its first element.

Yes I got the trick.

public void onClick(View v) {

            if( Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH ){
                imgDisplay.setSystemUiVisibility( View.SYSTEM_UI_FLAG_HIDE_NAVIGATION );

            }
            else if( Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB )
                imgDisplay.setSystemUiVisibility( View.STATUS_BAR_HIDDEN );
            else{}

    }

But it didn't solve my problem completely. I want to hide the horizontal scrollview too, which is in front of the imageView (below), which can't be hidden in this.

I use FLTK because Qt is not free. I don't choose wxWidgets, because my first test with a simple Hello, World! program produced an executable of 24 MB, FLTK 0.8 MB...

You're right:

$('#myTableRow').remove();

This works fine if your row has an id, such as:

<tr id="myTableRow"><td>blah</td></tr>

If you don't have an id, you can use any of jQuery's plethora of selectors.

Things changed a lot since the answer was posted. Now you will see a small key symbol on the right hand side of the URL bar.
Click the symbol and it will take you directly to the saved password dialog where you can remove the password.

Successfully tested in Chrome 49

@sfussenegger's answer explains how to make this work. But I'd say don't do it!

Experienced Java programmers use, and expect to see

        System.out.println(...);

and not

        out.println(...);

A static import of System.out or System.err is (IMO) bad style because:

• it breaks the accepted idiom, and
• it makes it harder to track down unwanted trace prints that were added during testing and not removed.

If you find yourself doing lots of output to System.out or System.err, I think it is a better to abstract the streams into attributes, local variables or methods. This will make your application more reusable.

list1 = (x[0] for x in source_list)
list2 = (x[1] for x in source_list)

I was just having the same issue with ReSharper 8.2 in Visual Studio 2013, and none of the usual solutions here of clearing caches, suspending ReSharper or re-installing ReSharper was working.

In my case I ended up solving it as follows... I looked at one of the symbols that it couldn't resolve and noted it was in System.Web.Http.dll. I then found that this was in the Microsoft.AspNet.WebApi.Core NuGet package. I used the package manager console to try and uninstall that package, except of course it told me that it couldn't due to other dependencies.

So I uninstalled each dependency up to and including Microsoft.AspNet.WebApi.Core, and then re-installed each package again in the reverse order. ReSharper picked everything up correctly as it was installed, and now seems fine.

1. Generate a random number using your favourite random-number generator
2. Multiply and divide it to get a number matching the number of characters in your code alphabet
3. Get the item at that index in your code alphabet.
4. Repeat from 1) until you have the length you want

e.g (in pseudo code)

int myInt = random(0, numcharacters)
char[] codealphabet = 'ABCDEF12345'
char random = codealphabet[i]
repeat until long enough

Axios is a promise based HTTP client for the browser and Node.js. Axios makes it easy to send asynchronous HTTP requests to REST endpoints and perform CRUD operations. It can be used in plain JavaScript or with a library such as Vue or React.

const axios = require('axios');

        var dataToPost = {
          email: "your email",
          password: "your password"
        };

        let axiosConfiguration = {
          headers: {
              'Content-Type': 'application/json;charset=UTF-8',
              "Access-Control-Allow-Origin": "*",
          }
        };

        axios.post('endpoint or url', dataToPost, axiosConfiguration)
        .then((res) => {
          console.log("Response: ", res);
        })
        .catch((err) => {
          console.log("error: ", err);
        })

I solved that problem by using a special setting for JsonSerializerSettings which is called TypeNameHandling.All

TypeNameHandling setting includes type information when serializing JSON and read type information so that the create types are created when deserializing JSON

Serialization:

var settings = new JsonSerializerSettings { TypeNameHandling = TypeNameHandling.All };
var text = JsonConvert.SerializeObject(configuration, settings);

Deserialization:

var settings = new JsonSerializerSettings { TypeNameHandling = TypeNameHandling.All };
var configuration = JsonConvert.DeserializeObject<YourClass>(json, settings);

The class YourClass might have any kind of base type fields and it will be serialized properly.

I know this has been answered, but in VB.net above 2013 (the lowest I've personally used) you can just compare strings with an = operator. This is the easiest way.

So basically:

If string1 = string2 Then
    'do a thing
End If

A quite common usage for '&&' is compiling software with autotools. For example:

./configure --prefix=/usr && make && sudo make install

Basically if the configure succeeds, make is run to compile, and if that succeeds, make is run as root to install the program. I use this when I am mostly sure that things will work, and it allows me to do other important things like look at stackoverflow an not 'monitor' the progress.

Sometimes I get really carried away...

tar xf package.tar.gz && ( cd package; ./configure && make && sudo make install ) && rm package -rf

I do this when for example making a linux from scratch box.

git log --full-history -- [file path] shows the changes of a file and works even if the file was deleted.

Example:

git log --full-history  -- myfile

If you want to see only the last commit, which deleted the file, use -1 in addition to the command above. Example:

git log --full-history -1 -- [file path]

See also my article: Which commit deleted a file.

also you can use this way. it will change your big drawble fit to your canvas:

Resources res = getResources();
Bitmap bitmap = BitmapFactory.decodeResource(res, yourDrawable);
yourCanvas.drawBitmap(bitmap, 0, 0, yourPaint);

If you use code analysis tools (e.g. FxCop), it will recommend that you mark a method static if that method don't access instance data. The rationale is that there is a performance gain. MSDN: CA1822 - Mark members as static.

It is more of a guideline than a rule, really...

Add div wrapper

<div id=myForm>
<select name=countries>
 <option value=af>Afghanistan</option>
 <option value=ax>Åland Islands</option>
 ...
 <option value=gs>South Georgia and the South Sandwich Islands</option>
 ...
</select>
</div>

and then write CSS

#myForm select { 
width:200px; }

#myForm select:focus {
width:auto; }

Hope this will help.

You can use timeit magic function for that.

%timeit CODE_LINE

Or on the cell

%%timeit 

SOME_CELL_CODE

Check more IPython magic functions at https://nbviewer.jupyter.org/github/ipython/ipython/blob/1.x/examples/notebooks/Cell%20Magics.ipynb

I used this for breadcrums in the category template page:

$cat_obj = $wp_query->get_queried_object();
$thiscat_id = $cat_obj->term_id;
$thiscat = get_category($thiscat_id);
$parentcat = get_category($thiscat->parent);

An alternative way to go around the problem, is to make the name of the session cookie be port related. For example:

• mysession8080 for the server running on port 8080
• mysession8000 for the server running on port 8000

Your code could access the webserver configuration to find out which port your server uses, and name the cookie accordingly.

Keep in mind that your application will receive both cookies, and you need to request the one that corresponds to your port.

There is no need to have the exact port number in the cookie name, but this is more convenient.

In general, the cookie name could encode any other parameter specific to the server instance you use, so it can be decoded by the right context.

For modern browsers only

If you target browsers that support the URLSearchParams API (most recent browsers) and FormData(formElement) constructor (most recent browsers), use this:

new URLSearchParams(new FormData(formElement)).toString()

Everywhere except IE

For browsers that support URLSearchParams but not the FormData(formElement) constructor, use this FormData polyfill and this code (works everywhere except IE):

new URLSearchParams(Array.from(new FormData(formElement))).toString()

Example

var form = document.querySelector('form');
var out = document.querySelector('output');

function updateResult() {
  try {
    out.textContent = new URLSearchParams(Array.from(new FormData(form)));
    out.className = '';
  } catch (e) {
    out.textContent = e;
    out.className = 'error';
  }
}

updateResult();
form.addEventListener('input', updateResult);

body { font-family: Arial, sans-serif; display: flex; flex-wrap: wrap; }
input[type="text"] { margin-left: 6px; max-width: 30px; }
label + label { margin-left: 10px; }
output { font-family: monospace; }
.error { color: #c00; }
div { margin-right: 30px; }

<!-- FormData polyfill for older browsers -->
<script src="https://unpkg.com/[email protected]/formdata.min.js"></script>
<div>
  <h3>Form</h3>
  <form id="form">
    <label>x:<input type="text" name="x" value="1"></label>
    <label>y:<input type="text" name="y" value="2"></label>
    <label>
    z:
    <select name="z">
      <option value="a" selected>a</option>
      <option value="b" selected>b</option>
    </select>
  </label>
  </form>
</div>
<div>
  <h3>Query string</h3>
  <output for="form"></output>
</div>

Compatible with IE 10

For even older browsers (e.g. IE 10), use the FormData polyfill, an Array.from polyfill if necessary and this code:

Array.from(
  new FormData(formElement),
  e => e.map(encodeURIComponent).join('=')
).join('&')

Take a pointer to the first element instead:

process_data (&something [0]);

You can omit the -jar option and start the jar file like this:

java -cp MyJar.jar;C:\externalJars\* mainpackage.MyMainClass

This also works like a charm

    <label class="radio-inline">_x000D_
      <input type="radio" name="optradio" checked>Option 1_x000D_

In Java, single quotes can only take one character, with escape if necessary. You need to use full quotation marks as follows for strings:

y = "hello";

You also used

System.out.println(g);

which I assume should be

System.out.println(y);

Note: When making char values (you'll likely use them later) you need single quotes. For example:

char foo='m';

Actually you don't even need the block:

  Dir.chdir 'C:/Users/name/Music'
  music = Dir['C:/Users/name/Music/*.{mp3, MP3}']
  puts 'what would you like to call the playlist?'
  playlist_name = gets.chomp + '.m3u'

  File.open(playlist_name, 'w').puts(music)

First of all, you should make an HTML form containing a file input element. You also need to set the form's enctype attribute to multipart/form-data:

<form method="post" enctype="multipart/form-data" action="/upload">
    <input type="file" name="file">
    <input type="submit" value="Submit">
</form>

Assuming the form is defined in index.html stored in a directory named public relative to where your script is located, you can serve it this way:

const http = require("http");
const path = require("path");
const fs = require("fs");

const express = require("express");

const app = express();
const httpServer = http.createServer(app);

const PORT = process.env.PORT || 3000;

httpServer.listen(PORT, () => {
  console.log(`Server is listening on port ${PORT}`);
});

// put the HTML file containing your form in a directory named "public" (relative to where this script is located)
app.get("/", express.static(path.join(__dirname, "./public")));

Once that's done, users will be able to upload files to your server via that form. But to reassemble the uploaded file in your application, you'll need to parse the request body (as multipart form data).

In Express 3.x you could use express.bodyParser middleware to handle multipart forms but as of Express 4.x, there's no body parser bundled with the framework. Luckily, you can choose from one of the many available multipart/form-data parsers out there. Here, I'll be using multer:

You need to define a route to handle form posts:

const multer = require("multer");

const handleError = (err, res) => {
  res
    .status(500)
    .contentType("text/plain")
    .end("Oops! Something went wrong!");
};

const upload = multer({
  dest: "/path/to/temporary/directory/to/store/uploaded/files"
  // you might also want to set some limits: https://github.com/expressjs/multer#limits
});


app.post(
  "/upload",
  upload.single("file" /* name attribute of <file> element in your form */),
  (req, res) => {
    const tempPath = req.file.path;
    const targetPath = path.join(__dirname, "./uploads/image.png");

    if (path.extname(req.file.originalname).toLowerCase() === ".png") {
      fs.rename(tempPath, targetPath, err => {
        if (err) return handleError(err, res);

        res
          .status(200)
          .contentType("text/plain")
          .end("File uploaded!");
      });
    } else {
      fs.unlink(tempPath, err => {
        if (err) return handleError(err, res);

        res
          .status(403)
          .contentType("text/plain")
          .end("Only .png files are allowed!");
      });
    }
  }
);

In the example above, .png files posted to /upload will be saved to uploaded directory relative to where the script is located.

In order to show the uploaded image, assuming you already have an HTML page containing an img element:

<img src="/image.png" />

you can define another route in your express app and use res.sendFile to serve the stored image:

app.get("/image.png", (req, res) => {
  res.sendFile(path.join(__dirname, "./uploads/image.png"));
});
