Just save some one time. I spent 3 hours to find out that it was just html encoding problem. Try this

if(get_magic_quotes_gpc()){
   $param = stripslashes($row['your column name']);
}else{
  $param = $row['your column name'];
}

$param = json_decode(html_entity_decode($param),true);
$json_errors = array(
JSON_ERROR_NONE => 'No error has occurred',
JSON_ERROR_DEPTH => 'The maximum stack depth has been exceeded',
JSON_ERROR_CTRL_CHAR => 'Control character error, possibly incorrectly encoded',
JSON_ERROR_SYNTAX => 'Syntax error',
);
echo 'Last error : ', $json_errors[json_last_error()], PHP_EOL, PHP_EOL;
print_r($param);

This is the most elegant solution I have created. It uses binary search, doing 10 iterations. The naive way was to do a while loop and increase the font size by 1 until the element started to overflow. You can determine when an element begins to overflow using element.offsetHeight and element.scrollHeight. If scrollHeight is bigger than offsetHeight, you have a font size that is too big.

Binary search is a much better algorithm for this. It also is limited by the number of iterations you want to perform. Simply call flexFont and insert the div id and it will adjust the font size between 8px and 96px.

I have spent some time researching this topic and trying different libraries, but ultimately I think this is the easiest and most straightforward solution that will actually work.

Note if you want you can change to use offsetWidth and scrollWidth, or add both to this function.

// Set the font size using overflow property and div height
function flexFont(divId) {
    var content = document.getElementById(divId);
    content.style.fontSize = determineMaxFontSize(content, 8, 96, 10, 0) + "px";
};

// Use binary search to determine font size
function determineMaxFontSize(content, min, max, iterations, lastSizeNotTooBig) {
    if (iterations === 0) {
        return lastSizeNotTooBig;
    }
    var obj = fontSizeTooBig(content, min, lastSizeNotTooBig);

    // if `min` too big {....min.....max.....}
    // search between (avg(min, lastSizeTooSmall)), min)
    // if `min` too small, search between (avg(min,max), max)
    // keep track of iterations, and the last font size that was not too big
    if (obj.tooBig) {
        (lastSizeTooSmall === -1) ?
            determineMaxFontSize(content, min / 2, min, iterations - 1, obj.lastSizeNotTooBig, lastSizeTooSmall) :
                determineMaxFontSize(content, (min + lastSizeTooSmall) / 2, min, iterations - 1, obj.lastSizeNotTooBig, lastSizeTooSmall);

    } else {
        determineMaxFontSize(content, (min + max) / 2, max, iterations - 1, obj.lastSizeNotTooBig, min);
    }
}

// determine if fontSize is too big based on scrollHeight and offsetHeight, 
// keep track of last value that did not overflow
function fontSizeTooBig(content, fontSize, lastSizeNotTooBig) {
    content.style.fontSize = fontSize + "px";
    var tooBig = content.scrollHeight > content.offsetHeight;
    return {
        tooBig: tooBig,
        lastSizeNotTooBig: tooBig ? lastSizeNotTooBig : fontSize
    };
}

SELECT * FROM `table_name` 
ORDER BY `table_name`.`column_name` DESC
LIMIT 1 

You can set the default search_path at the database level:

ALTER DATABASE <database_name> SET search_path TO schema1,schema2;

Or at the user or role level:

ALTER ROLE <role_name> SET search_path TO schema1,schema2;

Or if you have a common default schema in all your databases you could set the system-wide default in the config file with the search_path option.

When a database is created it is created by default from a hidden "template" database named template1, you could alter that database to specify a new default search path for all databases created in the future. You could also create another template database and use CREATE DATABASE <database_name> TEMPLATE <template_name> to create your databases.

You can set padding to your view by pro grammatically throughout below code -

view.setPadding(0,1,20,3);

And, also there are different type of padding available -

Padding

PaddingBottom

PaddingLeft

PaddingRight

PaddingTop

These, links will refer Android Developers site. Hope this helps you lot.

You might want to give XStream a shot, it is not complicated. It basically does the heavy lifting.

public static string ToFormattedCurrencyString(
    this decimal currencyAmount,
    string isoCurrencyCode,
    CultureInfo userCulture)
{
    var userCurrencyCode = new RegionInfo(userCulture.Name).ISOCurrencySymbol;

if (userCurrencyCode == isoCurrencyCode)
{
    return currencyAmount.ToString("C", userCulture);
}

return string.Format(
    "{0} {1}", 
    isoCurrencyCode, 
    currencyAmount.ToString("N2", userCulture));

}

Here's a question and answer for this: Difference between screen.availHeight and window.height()

Has pics too, so you can actually see the differences. Hope this helps.

Basically, $(window).height() give you the maximum height inside of the browser window (viewport), and$(document).height() gives you the height of the document inside of the browser. Most of the time, they will be exactly the same, even with scrollbars.

This might help you out:

Sub SelectFolder()
    Dim diaFolder As FileDialog
    Dim Fname As String

    Set diaFolder = Application.FileDialog(msoFileDialogFolderPicker)
    diaFolder.AllowMultiSelect = False
    diaFolder.Show

    Fname = diaFolder.SelectedItems(1)

    ActiveSheet.Range("B9") = Fname

End Sub

You need to add the source from where you're loading the data.

For Example:

$("#step1Content").load("yourpage.html");

Hope It will help you.

Today things have changed a little.

Now we avoid use ProgressDialog to show spinning progress:

If you want to put in your app a spinning progress you should use an Activity indicators:

http://developer.android.com/design/building-blocks/progress.html#activity

Taking for granted that the JSON you posted is actually what you are seeing in the browser, then the problem is the JSON itself.

The JSON snippet you have posted is malformed.

You have posted:

[{
        "name" : "shopqwe",
        "mobiles" : [],
        "address" : {
            "town" : "city",
            "street" : "streetqwe",
            "streetNumber" : "59",
            "cordX" : 2.229997,
            "cordY" : 1.002539
        },
        "shoe"[{
                "shoeName" : "addidas",
                "number" : "631744030",
                "producent" : "nike",
                "price" : 999.0,
                "sizes" : [30.0, 35.0, 38.0]
            }]

while the correct JSON would be:

[{
        "name" : "shopqwe",
        "mobiles" : [],
        "address" : {
            "town" : "city",
            "street" : "streetqwe",
            "streetNumber" : "59",
            "cordX" : 2.229997,
            "cordY" : 1.002539
        },
        "shoe" : [{
                "shoeName" : "addidas",
                "number" : "631744030",
                "producent" : "nike",
                "price" : 999.0,
                "sizes" : [30.0, 35.0, 38.0]
            }
        ]
    }
]

Generally speaking, they do the same job.
Nevertheless, the bracket notation gives you the opportunity to do stuff that you can't do with dot notation, like

var x = elem["foo[]"]; // can't do elem.foo[];

This can be extended to any property containing special characters.

If you are able to, use Boost. I have had good luck with their random library.

uniform_int should do what you want.

It is possibly to use the flag -o,--offline "Work offline" to prevent that.

Like this:

maven compile -o

Have a look at the advanced wheres documentation for Fluent: http://laravel.com/docs/queries#advanced-wheres

Here's an example of what you're trying to achieve:

DB::table('users')
    ->whereIn('id', function($query)
    {
        $query->select(DB::raw(1))
              ->from('orders')
              ->whereRaw('orders.user_id = users.id');
    })
    ->get();

This will produce:

select * from users where id in (
    select 1 from orders where orders.user_id = users.id
)

Although not exactly answering the question as formulated, but if you need or can take the end result as string you can also use

string s = Char.ConvertFromUtf32(56);

which will give you surrogate UTF-16 pairs if needed, protecting you if you are out side of the BMP.

Simply use

java.util.Collections.sort(list)

without String.CASE_INSENSITIVE_ORDER comparator parameter.

I'm the OP. After some research and testing, the answer is:

No, there is no way to do exactly that.

You need to open the connection first:

 SQLConnection.Open();

You can also "center" the text with:

vertical-align: middle;

Changing the image file to drawable-nodpi folder from drawable folder worked for me.

I was struggling a lot with different solutions including \vspace{-Xmm} on the top and bottom of the page and dealing with warnings and errors. Finally I found this answer:

You can change the margins of just one or more pages and then restore it to its default:

\usepackage{geometry}
...
... 
...
\newgeometry{top=5mm, bottom=10mm}     % use whatever margins you want for left, right, top and bottom.
...
... %<The contents of enlarged page(s)>
...    
\restoregeometry     %so it does not affect the rest of the pages.
...
... 
...

PS:

1- This can also fix the following warning:

LaTeX Warning: Float too large for page by ...pt on input line ...

2- For more detailed answer look at this.

3- I just found that this is more elaboration on Kevin Chen's answer.

I was running on Win7, Tomcat7 with maven-pom setup on Eclipse Mars with maven project enabled. On a NOT running server I only had to change from 3.1 to 3.0 on this screen:

For me it was important to have Dynamic Web Module disabled! Then change the version and then enable Dynamic Web Module again.

One checkbox to rule them all

For people still looking for plugin to control checkboxes through one that's lightweight, has out-of-the-box support for UniformJS and iCheck and gets unchecked when at least one of controlled checkboxes is unchecked (and gets checked when all controlled checkboxes are checked of course) I've created a jQuery checkAll plugin.

Feel free to check the examples on documentation page.

For this question example all you need to do is:

$( '#select_all' ).checkall({
    target: 'input[type="checkbox"][name="select"]'
});

Isn't that clear and simple?

Like well explained in the link below, an identifying relation is somewhat like a weak entity type relation to its parent in the ER conceptual model. UML style CADs for data modeling do not use ER symbols or concepts, and the kind of relations are: identifying, non-identifying and non-specific.

Identifying ones are relations parent/child where the child is kind of a weak entity (even at the traditional ER model its called identifying relationship), which does not have a real primary key by its own attributes and therefore cannot be identified uniquely by its own. Every access to the child table, on the physical model, will be dependent (inclusive semantically) on the parent's primary key, which turns into part or total of the child's primary key (also being a foreign key), generally resulting in a composite key on the child side. The eventual existing keys of the child itself are only pseudo or partial-keys, not sufficient to identify any instance of that type of Entity or Entity Set, without the parent's PK.

Non-identifying relationship are the ordinary relations (partial or total), of completely independent entity sets, whose instances do not depend on each others' primary keys to be uniquely identified, although they might need foreign keys for partial or total relationships, but not as the primary key of the child. The child has its own primary key. The parent idem. Both independently. Depending on the cardinality of the relationship, the PK of one goes as a FK to the other (N side), and if partial, can be null, if total, must be not null. But, at a relationship like this, the FK will never be also the PK of the child, as when an identifying relationship is the case.

The way you have it is correct at the moment. Either the id of the select is not what you say or you have some issues in the dom.

Check the Id of the element and also check your markup validates at here at W3c.

Without a valid dom jQuery cannot work correctly with the selectors.

If the id's are correct and your dom validates then the following applies:

To Read Select Option Value

$('#selectId').val();

To Set Select Option Value

$('#selectId').val('newValue');

To Read Selected Text

$('#selectId>option:selected').text();

Here the trait fully emulates running controller by laravel router (including support of middlewares and dependency injection). Tested only with 5.4 version

<?php

namespace App\Traits;

use Illuminate\Pipeline\Pipeline;
use Illuminate\Routing\ControllerDispatcher;
use Illuminate\Routing\MiddlewareNameResolver;
use Illuminate\Routing\SortedMiddleware;

trait RunsAnotherController
{
    public function runController($controller, $method = 'index')
    {
        $middleware = $this->gatherControllerMiddleware($controller, $method);

        $middleware = $this->sortMiddleware($middleware);

        return $response = (new Pipeline(app()))
            ->send(request())
            ->through($middleware)
            ->then(function ($request) use ($controller, $method) {
                return app('router')->prepareResponse(
                    $request, (new ControllerDispatcher(app()))->dispatch(
                    app('router')->current(), $controller, $method
                )
                );
            });
    }

    protected function gatherControllerMiddleware($controller, $method)
    {
        return collect($this->controllerMidlleware($controller, $method))->map(function ($name) {
            return (array)MiddlewareNameResolver::resolve($name, app('router')->getMiddleware(), app('router')->getMiddlewareGroups());
        })->flatten();
    }

    protected function controllerMidlleware($controller, $method)
    {
        return ControllerDispatcher::getMiddleware(
            $controller, $method
        );
    }

    protected function sortMiddleware($middleware)
    {
        return (new SortedMiddleware(app('router')->middlewarePriority, $middleware))->all();
    }
}

Then just add it to your class and run the controller. Note, that dependency injection will be assigned with your current route.

class CustomController extends Controller {
    use RunsAnotherController;

    public function someAction() 
    {
        $controller = app()->make('App\Http\Controllers\AnotherController');

        return $this->runController($controller, 'doSomething');
    }
}

If you are using Fontawesome you can do this :

<input type="text" style="font-family:Arial, FontAwesome"  placeholder="&#xf007;" />

The complete list of unicode can be found in the The complete Font Awesome 4.6.3 icon reference

This is done with

ANALYZE TABLE table_name;

Read more about it here.

ANALYZE TABLE analyzes and stores the key distribution for a table. During the analysis, the table is locked with a read lock for MyISAM, BDB, and InnoDB. This statement works with MyISAM, BDB, InnoDB, and NDB tables.

You can also use Bootstrap 4 flex classes

Like: .align-item-center and .justify-content-center

We can use these classes identically for all device view.

Like: .align-item-sm-center, .align-item-md-center, .justify-content-xl-center, .justify-content-lg-center, .justify-content-xs-center

.text-center class is used to align text in center.

Type ctor, and then press the Tab key.

If you're using Selenium with Firefox you should be able to use EXSLT extensions, and regexp:test()

Does this work for you?

String expr = "//*[regexp:test(@id, 'sometext[0-9]+_text')]";
driver.findElement(By.xpath(expr));

You want the "popen" function. Here's an example of running the command "ls /etc" and outputing to the console.

#include <stdio.h>
#include <stdlib.h>


int main( int argc, char *argv[] )
{

  FILE *fp;
  char path[1035];

  /* Open the command for reading. */
  fp = popen("/bin/ls /etc/", "r");
  if (fp == NULL) {
    printf("Failed to run command\n" );
    exit(1);
  }

  /* Read the output a line at a time - output it. */
  while (fgets(path, sizeof(path), fp) != NULL) {
    printf("%s", path);
  }

  /* close */
  pclose(fp);

  return 0;
}

//Filter out array elements with keys shorter than 4 characters // By using Anonymous function with Closure...

function comparison($min)
{
   return function($item) use ($min) { 
      return strlen($item) >= $min;   
   }; 
}

$input = array(
  0      => "val 0",
  "one"  => "val one",
  "two"  => "val two",
  "three"=> "val three",
  "four" => "val four",  
  "five" => "val five",    
  "6"    => "val 6"    
);

$output = array_filter(array_keys($input), comparison(4));

print_r($output);

The following worked for me (based on example for a Django model, but you can pretty much use the code of the delete method on its own).

import boto3
from boto3.session import Session
from django.conf import settings

class Video(models.Model):
    title=models.CharField(max_length=500)
    description=models.TextField(default="")
    creation_date=models.DateTimeField(default=timezone.now)
    videofile=models.FileField(upload_to='videos/', null=True, verbose_name="")
    tags = TaggableManager()

    actions = ['delete']

    def __str__(self):
        return self.title + ": " + str(self.videofile)

    def delete(self, *args, **kwargs):
        session = Session (settings.AWS_ACCESS_KEY_ID, settings.AWS_SECRET_ACCESS_KEY)
        s3_resource = session.resource('s3')
        s3_bucket = s3_resource.Bucket(settings.AWS_STORAGE_BUCKET_NAME)

        file_path = "media/" + str(self.videofile)
        response = s3_bucket.delete_objects(
            Delete={
                'Objects': [
                    {
                        'Key': file_path
                    }
                ]
            })
        super(Video, self).delete(*args, **kwargs)

The API Doc are very clear on this.

All generators implement the interface org.hibernate.id.IdentifierGenerator. This is a very simple interface. Some applications can choose to provide their own specialized implementations, however, Hibernate provides a range of built-in implementations. The shortcut names for the built-in generators are as follows:

increment

generates identifiers of type long, short or int that are unique only when no other process is inserting data into the same table. Do not use in a cluster.

identity

supports identity columns in DB2, MySQL, MS SQL Server, Sybase and HypersonicSQL. The returned identifier is of type long, short or int.

sequence

uses a sequence in DB2, PostgreSQL, Oracle, SAP DB, McKoi or a generator in Interbase. The returned identifier is of type long, short or int

hilo

uses a hi/lo algorithm to efficiently generate identifiers of type long, short or int, given a table and column (by default hibernate_unique_key and next_hi respectively) as a source of hi values. The hi/lo algorithm generates identifiers that are unique only for a particular database.

seqhilo

uses a hi/lo algorithm to efficiently generate identifiers of type long, short or int, given a named database sequence.

uuid

uses a 128-bit UUID algorithm to generate identifiers of type string that are unique within a network (the IP address is used). The UUID is encoded as a string of 32 hexadecimal digits in length.

guid

uses a database-generated GUID string on MS SQL Server and MySQL.

native

selects identity, sequence or hilo depending upon the capabilities of the underlying database.

assigned

lets the application assign an identifier to the object before save() is called. This is the default strategy if no element is specified.

select

retrieves a primary key, assigned by a database trigger, by selecting the row by some unique key and retrieving the primary key value.

foreign

uses the identifier of another associated object. It is usually used in conjunction with a primary key association.

sequence-identity

a specialized sequence generation strategy that utilizes a database sequence for the actual value generation, but combines this with JDBC3 getGeneratedKeys to return the generated identifier value as part of the insert statement execution. This strategy is only supported on Oracle 10g drivers targeted for JDK 1.4. Comments on these insert statements are disabled due to a bug in the Oracle drivers.

If you are building a simple application with not much concurrent users, you can go for increment, identity, hilo etc.. These are simple to configure and did not need much coding inside the db.

You should choose sequence or guid depending on your database. These are safe and better because the id generation will happen inside the database.

Update: Recently we had an an issue with idendity where primitive type (int) this was fixed by using warapper type (Integer) instead.

If you're running cPanel/WHM, make sure that IP is whitelisted in the firewall. You will als need to add that IP to the remote SQL IP list in the cPanel account you're trying to connect to.

In NumPy it is quite simple

import numpy as np
P=2.45
S=[22, 33, 45.6, 21.6, 51.8]
SP = P*np.array(S)

I recommend taking a look at the NumPy tutorial for an explanation of the full capabilities of NumPy's arrays:

You can get the attributes of a model object returned as a hash using either

@post.attributes

or

@post.as_json

as_json allows you to include associations and their attributes as well as specify which attributes to include/exclude (see documentation). However, if you only need the attributes of the base object, benchmarking in my app with ruby 2.2.3 and rails 4.2.2 demonstrates that attributes requires less than half as much time as as_json.

I believe that I have the simplest answer yet using Spring Boot 1.4, included imports for the test class.:

public class SomeClass {  /// this goes in it's own file
//// fields go here
}

import org.junit.Before
import org.junit.Test
import org.junit.runner.RunWith
import org.springframework.beans.factory.annotation.Autowired
import org.springframework.boot.test.autoconfigure.web.servlet.WebMvcTest
import org.springframework.http.MediaType
import org.springframework.test.context.junit4.SpringRunner
import org.springframework.test.web.servlet.MockMvc

import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.post
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status

@RunWith(SpringRunner.class)
@WebMvcTest(SomeController.class)
public class ControllerTest {

  @Autowired private MockMvc mvc;
  @Autowired private ObjectMapper mapper;

  private SomeClass someClass;  //this could be Autowired
                                //, initialized in the test method
                                //, or created in setup block
  @Before
  public void setup() {
    someClass = new SomeClass(); 
  }

  @Test
  public void postTest() {
    String json = mapper.writeValueAsString(someClass);
    mvc.perform(post("/someControllerUrl")
       .contentType(MediaType.APPLICATION_JSON)
       .content(json)
       .accept(MediaType.APPLICATION_JSON))
       .andExpect(status().isOk());
  }

}

The problem is also identified in your status bar at the bottom:

You are in overwrite mode instead of insert mode.

The “Insert” key toggles between insert and overwrite modes.

myTest.js

module.exports.get = function () {};

exports.put = function () {};

console.log(module.exports)
// output: { get: [Function], put: [Function] }

exports and module.exports are the same and a reference to the same object. You can add properties by both ways as per your convenience.

Yep, just add parenthesis (calling the function). Make sure the function is in scope and actually returns something.

<ul class="ui-listview ui-radiobutton" ng-repeat="meter in meters">
  <li class = "ui-divider">
    {{ meter.DESCRIPTION }}
    {{ htmlgeneration() }}
  </li>
</ul>

From page 106 of the ggplot2 book by Hadley Wickham:

The default colour scheme, scale_colour_hue picks evenly spaced hues around the hcl colour wheel.

With a bit of reverse engineering you can construct this function:

ggplotColours <- function(n = 6, h = c(0, 360) + 15){
  if ((diff(h) %% 360) < 1) h[2] <- h[2] - 360/n
  hcl(h = (seq(h[1], h[2], length = n)), c = 100, l = 65)
}

Demonstrating this in barplot:

y <- 1:3
barplot(y, col = ggplotColours(n = 3))

You can also use @hourly instant of 0 * * * *

Take a look at strtol(), if you're using the C standard library.

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.

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.

"exit" is an event that gets triggered when node finish it's event loop internally, it's not triggered when you terminate the process externally.

What you're looking for is executing something on a SIGINT.

The docs at http://nodejs.org/api/process.html#process_signal_events give an example:

Example of listening for SIGINT:

// Start reading from stdin so we don't exit.
process.stdin.resume();

process.on('SIGINT', function () {
  console.log('Got SIGINT.  Press Control-D to exit.');
});

Note: this seems to interrupt the sigint and you would need to call process.exit() when you finish with your code.

I met the same problem on my Ubuntu 16.04 system. I managed to fix it by re-installing pip with the following command:

curl https://bootstrap.pypa.io/get-pip.py | sudo python3

->where() support passing any string to it and it will use it in the query.

You can try using this:

$this->db->select('*')->from('certs');
$this->db->where('`id` NOT IN (SELECT `id_cer` FROM `revokace`)', NULL, FALSE);

The ,NULL,FALSE in the where() tells CodeIgniter not to escape the query, which may mess it up.

UPDATE: You can also check out the subquery library I wrote.

$this->db->select('*')->from('certs');
$sub = $this->subquery->start_subquery('where_in');
$sub->select('id_cer')->from('revokace');
$this->subquery->end_subquery('id', FALSE);

Answer Given by rushUp Is correct but this will be more convenient

for (let [index, val] of array.entries() || []) {
   // your code goes here    
}

Make the class public.

class NewClass
{

}

is the same as:

internal class NewClass
{

}

so the class has to be public

You could try to split on (?<=\D)(?=\d)|(?<=\d)(?=\D), like:

str.split("(?<=\\D)(?=\\d)|(?<=\\d)(?=\\D)");

It matches positions between a number and not-a-number (in any order).

• (?<=\D)(?=\d) - matches a position between a non-digit (\D) and a digit (\d)
• (?<=\d)(?=\D) - matches a position between a digit and a non-digit.

Use Math.round(), possibly in conjunction with MidpointRounding.AwayFromZero

eg:

Math.Round(1.2) ==> 1
Math.Round(1.5) ==> 2
Math.Round(2.5) ==> 2
Math.Round(2.5, MidpointRounding.AwayFromZero) ==> 3

Well, the only thing I can make it work is like so:

servers: >
    dev.example.com,
    another.example.com

@Value("${servers}")
private String[] array;

And dont forget the @Configuration above your class....

Without the "," separation, no such luck...

Works too (boot 1.5.8 versie)

servers: 
       dev.example.com,
       another.example.com

Five years later with introduction of React Hooks there is now much more elegant way of doing it with use useContext hook.

You define context in a global scope, export variables, objects and functions in the parent component and then wrap children in the App in a context provided and import whatever you need in child components. Below is a proof of concept.

import React, { useState, useContext } from "react";
import ReactDOM from "react-dom";
import styles from "./styles.css";

// Create context container in a global scope so it can be visible by every component
const ContextContainer = React.createContext(null);

const initialAppState = {
  selected: "Nothing"
};

function App() {
  // The app has a state variable and update handler
  const [appState, updateAppState] = useState(initialAppState);

  return (
    <div>
      <h1>Passing state between components</h1>

      {/* 
          This is a context provider. We wrap in it any children that might want to access
          App's variables.
          In 'value' you can pass as many objects, functions as you want. 
           We wanna share appState and its handler with child components,           
       */}
      <ContextContainer.Provider value={{ appState, updateAppState }}>
        {/* Here we load some child components */}
        <Book title="GoT" price="10" />
        <DebugNotice />
      </ContextContainer.Provider>
    </div>
  );
}

// Child component Book
function Book(props) {
  // Inside the child component you can import whatever the context provider allows.
  // Earlier we passed value={{ appState, updateAppState }}
  // In this child we need the appState and the update handler
  const { appState, updateAppState } = useContext(ContextContainer);

  function handleCommentChange(e) {
    //Here on button click we call updateAppState as we would normally do in the App
    // It adds/updates comment property with input value to the appState
    updateAppState({ ...appState, comment: e.target.value });
  }

  return (
    <div className="book">
      <h2>{props.title}</h2>
      <p>${props.price}</p>
      <input
        type="text"
        //Controlled Component. Value is reverse vound the value of the variable in state
        value={appState.comment}
        onChange={handleCommentChange}
      />
      <br />
      <button
        type="button"
        // Here on button click we call updateAppState as we would normally do in the app
        onClick={() => updateAppState({ ...appState, selected: props.title })}
      >
        Select This Book
      </button>
    </div>
  );
}

// Just another child component
function DebugNotice() {
  // Inside the child component you can import whatever the context provider allows.
  // Earlier we passed value={{ appState, updateAppState }}
  // but in this child we only need the appState to display its value
  const { appState } = useContext(ContextContainer);

  /* Here we pretty print the current state of the appState  */
  return (
    <div className="state">
      <h2>appState</h2>
      <pre>{JSON.stringify(appState, null, 2)}</pre>
    </div>
  );
}

const rootElement = document.body;
ReactDOM.render(<App />, rootElement);

You can run this example in the Code Sandbox editor.

//add a reference to System.Windows.Forms.dll

public partial class MainWindow : Window, System.Windows.Forms.IWin32Window
{
    public MainWindow()
    {
        InitializeComponent();
    }

    private void button_Click(object sender, RoutedEventArgs e)
    {
        var fbd = new FolderBrowserDialog();
        fbd.ShowDialog(this);
    }

    IntPtr System.Windows.Forms.IWin32Window.Handle
    {
        get
        {
            return ((HwndSource)PresentationSource.FromVisual(this)).Handle;
        }
    }
}

In my case, Run as Administrator does not help. I solved the problem by changing the Build-in Account to Local System in Configuration Manager.

Type switches can also be used with reflection stuff:

var str = "hello!"
var obj = reflect.ValueOf(&str)

switch obj.Elem().Interface().(type) {
case string:
    log.Println("obj contains a pointer to a string")
default:
    log.Println("obj contains something else")
}

You can use something like this:

for i in `cat foo.txt`
do
    sudo $i
done

Though if the commands have arguments (i.e. there is whitespace in the lines) you may have to monkey around with that a bit to protect the whitepace so that the whole string is seen by sudo as a command. But it gives you an idea on how to start.

I'm not sure there is an api to get the default system font name. So I just get the name like this :

    //get system default font
    UILabel *label = [[UILabel alloc] init];        
    fontname = label.font.fontName;
    [label release];

Looks stupid but it works.

After wasting a lot of time in finding its solution, I've found one. For your convenience I've used the complete code that you can replace your whole file with.

This is a general answer. Let's say you want to import a file named testjs.js into your angular 2 component. Create testjs.js in your assets folder:

assets > testjs.js

function test(){
    alert('TestingFunction')
}

include testjs.js in your index.html

index.html

<!doctype html>
<html>
<head>
  <meta charset="utf-8">
  <title>Project1</title>
  <base href="/">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="icon" type="image/x-icon" href="favicon.ico">

  <script src="./assets/testjs.js"></script>

</head>
<body>
  <app-root>Loading...</app-root>
</body>
</html>

In your app.component.ts or in any component.ts file where you want to call this js declare a variable and call the function like below:

app.component.ts

import { Component } from '@angular/core';

declare var test: any;


@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})

export class AppComponent {
  title = 'app works!';


  f(){
    new test();
  }
}

Finally in your app.component.html test the function

app.component.html

<h1>
  <button (click)='f()'>Test</button>
</h1>

Maybe a better solution for this as I figured out. Spec says as cited from @JohnnyCoder :

media.pause()

Sets the paused attribute to true, loading the media resource if necessary.

--> loading it

if (videoEl.readyState !== 4) {
    videoEl.load();
}
videoEl.play();

indicates the readiness state of the media HAVE_ENOUGH_DATA = 4

Basically only load the video if it is not already loaded. Mentioned error occurred for me, because video was not loaded. Maybe better than using a timeout.

To make the numbers overwrite each other, you can do something like this:

for i in range(1,100):
    print "\r",i,

That should work as long as the number is printed in the first column.

EDIT: Here's a version that will work even if it isn't printed in the first column.

prev_digits = -1
for i in range(0,1000):
    print("%s%d" % ("\b"*(prev_digits + 1), i)),
    prev_digits = len(str(i))

I should note that this code was tested and works just fine in Python 2.5 on Windows, in the WIndows console. According to some others, flushing of stdout may be required to see the results. YMMV.

I had the same issue too, the problem is exacerbated with the download link now only working for Visual Studio 2017, and installing the package from the download link did nothing for VS2015, although it took up 5gB of space.

I looked everywhere on how to do it with the Nu Get package manager and I couldn't find the solution.

It turns out it's even simpler than that, all you have to do is right-click the project or solution in the Solution Explorer from within Visual Studio, and click "Install Missing Components"

You can use GCD. It is a little more verbose than @synchronized, but works as a replacement:

let serialQueue = DispatchQueue(label: "com.test.mySerialQueue")
serialQueue.sync {
    // code
}

In regards to setting the logging.properties value

org.apache.tomcat.util.digester.Digester.level = SEVERE

... if you're running an embedded tomcat server in eclipse, the logging.properties file used by default is the JDK default at %JAVA_HOME%/jre/lib/logging.properties

If you want to use a different logging.properties file (e.g. in the tomcat server's conf directory), this needs to be set via the java.util.logging.config.file system property. e.g. to use the logging properties defined in the file c:\java\apache-tomcat-7.0.54\conf\eclipse-logging.properties, add this to the VM argument list:

-Djava.util.logging.config.file="c:\java\apache-tomcat-7.0.54\conf\eclipse-logging.properties"

(double-click on the server icon, click 'Open launch configuration', select the Arguments tab, then enter this in the 'VM arguments' text box)

You might also find it useful to add the VM argument

-Djava.util.logging.SimpleFormatter.format="%1$tc %4$s %3$s %5$s%n"

as well, which will then include the source logger name in the output, which should make it easier to determine which logger to throttle in the logging.properties file (as per http://docs.oracle.com/javase/7/docs/api/java/util/logging/SimpleFormatter.html )

You can define a context for your application say ExampleContext which will hold the context of your application and then use it to instantiate an activity like this:

var intent = new Intent(Application.ApplicationContext, typeof(Activity2));
intent.AddFlags(ActivityFlags.NewTask);
Application.ApplicationContext.StartActivity(intent);

Please bear in mind that this code is written in C# as I use MonoDroid, but I believe it is very similar to Java. For how to create an ApplicationContext look at this thread

This has nothing to do with the MIME type, but the Content-Disposition header, which should be something like:

Content-Disposition: attachment; filename=genome.jpeg;

Make sure it is actually correctly passed to the client (not filtered by the server, proxy or something). Also you could try to change the order of writing headers and set them before getting output stream.

While respond_to? will return true only for public methods, checking for "method definition" on a class may also pertain to private methods.

On Ruby v2.0+ checking both public and private sets can be achieved with

Foo.private_instance_methods.include?(:bar) || Foo.instance_methods.include?(:bar)

For DataFrame df:

import numpy as np
index = df['b'].index[df['b'].apply(np.isnan)]

will give you back the MultiIndex that you can use to index back into df, e.g.:

df['a'].ix[index[0]]
>>> 1.452354

For the integer index:

df_index = df.index.values.tolist()
[df_index.index(i) for i in index]
>>> [3, 6]

To change transparency on an svg code the simplest way is to open it on any text editor and look for the style attributes. It depends on the svg creator the way the styles are displayed. As i am an Inkscape user the usual way it set the style values is through a style tag just as if it were html but using svg native attributes like fill, stroke, stroke-width, opacity and so on. opacity affects the whole svg object, or path or group in which its stated and fill-opacity, stroke-opacity will affect just the fill and the stroke transparency. That said, I have also used and tasted to just use fill and instead of using#fff use instead the rgba standard like this rgba(255, 255, 255, 1) just as in css. This works fine for must modern browsers.

Keep in mind that if you intend to further reedit your svg the best practice, in my experience, is to always keep an untouched version at hand. Inkscape is more flexible with hand changed svgs but Illustrator and CorelDraw may have issues importing and edited svg.

Notice that in the last example the fill-opacity has been removed as rgba standard covers both color and alpha channel.

you can use webview to show the pdf inside an application , for that you have to :

1. convert the pdf to html file and store it in asset folder
2. load the html file to the web view ,

Many pdf to html online converter available.

Example:

    consent_web = (WebView) findViewById(R.id.consentweb);
    consent_web.getSettings().setLoadWithOverviewMode(true);
    consent_web.getSettings().setUseWideViewPort(true);
    consent_web.loadUrl("file:///android_asset/spacs_html.html");

MySQL doesn't allow selecting from a table and update in the same table at the same time. But there is always a workaround :)

This doesn't work >>>>

UPDATE table1 SET col1 = (SELECT MAX(col1) from table1) WHERE col1 IS NULL;

But this works >>>>

UPDATE table1 SET col1 = (SELECT MAX(col1) FROM (SELECT * FROM table1) AS table1_new) WHERE col1 IS NULL;

This is not an answer, but too long for a comment.

In reply to JP's answers / comments, I have run the following test to compare the performance of the 2 methods. The Profiler object is a custom class - but in summary, it uses a kernel32 function which is fairly accurate (Private Declare Sub GetLocalTime Lib "kernel32" (lpSystemTime As SYSTEMTIME)).

Sub test()

  Dim origNum As String
  Dim creditOrDebit As String
  Dim b As Boolean
  Dim p As Profiler
  Dim i As Long

  Set p = New_Profiler

  origNum = "30062600006"
  creditOrDebit = "D"

  p.startTimer ("nested_ifs")

  For i = 1 To 1000000

    If creditOrDebit = "D" Then
      If origNum = "006260006" Then
        b = True
      ElseIf origNum = "30062600006" Then
        b = True
      End If
    End If

  Next i

  p.stopTimer ("nested_ifs")
  p.startTimer ("or_and")

  For i = 1 To 1000000

    If (origNum = "006260006" Or origNum = "30062600006") And creditOrDebit = "D" Then
      b = True
    End If

  Next i

  p.stopTimer ("or_and")

  p.printReport

End Sub

The results of 5 runs (in ms for 1m loops):

If creditOrDebit is not "D", JP's code runs faster (around 60ms vs. 125ms for the or/and code).

    int x=550;
    string s=" ";
    string y=" ";

    while (x>0)
    {

        s += x%2;
        x=x/2;
    }


    Console.WriteLine(Reverse(s));
}

{
    char[] charArray = s.ToCharArray();
    Array.Reverse( charArray );
    return new string( charArray );

If you just want to get the information of current directory, you can type:

pwd

and you don't need to use the Nautilus, or you can use a teamviewer software to remote connect to the computer, you can get everything you want.

gawk '{$1=$1}1' OFS="\n" file

You could always use apache commons' DateUtils class. It has the static method isSameDay() which "Checks if two date objects are on the same day ignoring time."

static boolean isSameDay(Date date1, Date date2) 

This is a bit of a pain on Windows. Here's what I do.

Install latest Sun JDK, e.g. 6u11, in path like c:\install\jdk\sun\6u11, then let the installer install public JRE in the default place (c:\program files\blah). This will setup your default JRE for the majority of things.

Install older JDKs as necessary, like 5u18 in c:\install\jdk\sun\5u18, but don't install the public JREs.

When in development, I have a little batch file that I use to setup a command prompt for each JDK version. Essentially just set JAVA_HOME=c:\jdk\sun\JDK_DESIRED and then set PATH=%JAVA_HOME%\bin;%PATH%. This will put the desired JDK first in the path and any secondary tools like Ant or Maven can use the JAVA_HOME variable.

The path is important because most public JRE installs put a linked executable at c:\WINDOWS\System32\java.exe, which usually overrides most other settings.

A terser way, either with rev :

x[!(!duplicated(x) & rev(!duplicated(rev(x))))]

... rather than fromLast:

x[!(!duplicated(x) & !duplicated(x, fromLast = TRUE))]

... and as a helper function to provide either logical vector or elements from original vector :

duplicates <- function(x, as.bool = FALSE) {
    is.dup <- !(!duplicated(x) & rev(!duplicated(rev(x))))
    if (as.bool) { is.dup } else { x[is.dup] }
}

Treating vectors as data frames to pass to table is handy but can get difficult to read, and the data.table solution is fine but I'd prefer base R solutions for dealing with simple vectors like IDs.

From the fine manual.

You must own the table to use ALTER TABLE.

Or be a database superuser.

ERROR: must be owner of relation contact

PostgreSQL error messages are usually spot on. This one is spot on.

Those two parameters (or variants of) are sent, by convention, with all events.

• sender: The object which has raised the event
• e an instance of EventArgs including, in many cases, an object which inherits from EventArgs. Contains additional information about the event, and sometimes provides ability for code handling the event to alter the event somehow.

In the case of the events you mentioned, neither parameter is particularly useful. The is only ever one page raising the events, and the EventArgs are Empty as there is no further information about the event.

Looking at the 2 parameters separately, here are some examples where they are useful.

sender

Say you have multiple buttons on a form. These buttons could contain a Tag describing what clicking them should do. You could handle all the Click events with the same handler, and depending on the sender do something different

private void HandleButtonClick(object sender, EventArgs e)
{
    Button btn = (Button)sender;
    if(btn.Tag == "Hello")
      MessageBox.Show("Hello")
    else if(btn.Tag == "Goodbye")
       Application.Exit();
    // etc.
}

Disclaimer : That's a contrived example; don't do that!

e

Some events are cancelable. They send CancelEventArgs instead of EventArgs. This object adds a simple boolean property Cancel on the event args. Code handling this event can cancel the event:

private void HandleCancellableEvent(object sender, CancelEventArgs e)
{
    if(/* some condition*/)
    {
       // Cancel this event
       e.Cancel = true;
    }
}

After updating my Android SDK I stumbled upon this very problem and I tried many ways without success. What was most irritating to me when searching for a fix, were the lots of answers suggesting to change the CompileSdkVersion to a certain number while obviously this number changes with time, so here's what I did instead.

I created a new project and ran it on the emulator to make sure it's working, then checked its "\android\app\build.gradle" file and copied the numeric value of CompileSdkVersion and pasted into the same file in my other project that could not be built properly anymore. Now my problem's gone. Hope that helps.

If the selector is contained within a variable, the code below may be helpful:

selector_name = $this.attr('name');
//selector_name = users[0][first:name]

escaped_selector_name = selector_name.replace(/(:|\.|\[|\])/g,'\\$1');
//escaped_selector_name = users\\[0\\]\\[first\\:name\\]

In this case we prefix all special characters with double backslash.

You can use dict to convert string to boolean. Change this line flag = bool(reader[0]) to:

flag = {'True': True, 'False': False}.get(reader[0], False) # default is False

You can use:

var queryString = url.Substring(url.IndexOf('?')).Split('#')[0]
System.Web.HttpUtility.ParseQueryString(queryString)

I have no idea what linux distribution "ubuntu centOS" is. Ubuntu and CentOS are two different distributions.

To answer the question in the header: To install make in ubuntu you have to install build-essentials

sudo apt-get install build-essential

You can use find to look for the selected option that is a descendant of the node(s) pointed to by the current jQuery object:

var cur_value = $(this).find('option:selected').text();

Since this is likely an immediate child, I would actually suggest using .children instead:

var cur_value = $(this).children('option:selected').text();

Some Linux based MySQL installations require case sensitive. Work around is to apply nativeQuery.

@Query(value = 'select ID, CLUMN2, CLUMN3 FROM VENDOR c where c.ID = :ID', nativeQuery = true)

Try This:

Select race_id, race_description
, Case patIndex ('%[ /-]%', LTrim (race_description))
    When 0 Then LTrim (race_description)
    Else substring (LTrim (race_description), 1, patIndex ('%[ /-]%', LTrim (race_description)) - 1)
End race_abbreviation

        if(jsonViewAnnotation!=null){
            boolean jsonViewPresent = false;
            Class[] viewNames = jsonViewAnnotation.value();
            if(jsonViewName!=null && Arrays.asList(viewNames).contains(jsonViewName) ){
                fields.add(field);
            }
        }
    }
    return fields;

Run

docker images

to see a list of the images on the host. Let's say you have an image called awesomesauce. In your terminal, cd to the directory where you want to export the image to. Now run:

docker save awesomesauce:latest > awesomesauce.tar

Copy the tar file to a thumb drive or whatever, and then copy it to the new host computer.

Now from the new host do:

docker load < awesomesauce.tar

It looks like in the ECMAScript 6 proposal there are the Array methods find() and findIndex(). MDN also offers polyfills which you can include to get the functionality of these across all browsers.

find():

function isPrime(element, index, array) {
    var start = 2;
    while (start <= Math.sqrt(element)) {
        if (element % start++ < 1) return false;
    }
    return (element > 1);
}

console.log( [4, 6, 8, 12].find(isPrime) ); // undefined, not found
console.log( [4, 5, 8, 12].find(isPrime) ); // 5

findIndex():

function isPrime(element, index, array) {
    var start = 2;
    while (start <= Math.sqrt(element)) {
        if (element % start++ < 1) return false;
    }
    return (element > 1);
}

console.log( [4, 6, 8, 12].findIndex(isPrime) ); // -1, not found
console.log( [4, 6, 7, 12].findIndex(isPrime) ); // 2

In my case the issue was related to too long log outputting into IntelliJ IDEA console (OS windows 10).

As the accepted answer, John Feminella stated that:

The proper way to check properties of duck-typed objects is to ask them if they quack, not to see if they fit in a duck-sized container. The "compare it directly" approach will give the wrong answer for many functions, like builtins.

Even though, there're two libs to distinguish functions strictly, I draw an exhaustive comparable table:

The "duck typing" is a preferred solution for general purpose:

def detect_function(obj):
    return hasattr(obj,"__call__")

In [26]: detect_function(detect_function)
Out[26]: True
In [27]: callable(detect_function)
Out[27]: True

As for the builtins function

In [43]: callable(hasattr)
Out[43]: True

When go one more step to check if builtin function or user-defined funtion

#check inspect.isfunction and type.FunctionType
In [46]: inspect.isfunction(detect_function)
Out[46]: True
In [47]: inspect.isfunction(hasattr)
Out[47]: False
In [48]: isinstance(detect_function, types.FunctionType)
Out[48]: True
In [49]: isinstance(getattr, types.FunctionType)
Out[49]: False
#so they both just applied to judge the user-definded

Determine if builtin function

In [50]: isinstance(getattr, types.BuiltinFunctionType)
Out[50]: True
In [51]: isinstance(detect_function, types.BuiltinFunctionType)
Out[51]: False

Summary

Employ callable to duck type checking a function,
Use types.BuiltinFunctionType if you have further specified demand.

Based on previous answers I've created this comfortable helper to support all DisplayAttribute properties in a readable way:

public static class EnumExtensions
    {
        public static DisplayAttributeValues GetDisplayAttributeValues(this Enum enumValue)
        {
            var displayAttribute = enumValue.GetType().GetMember(enumValue.ToString()).First().GetCustomAttribute<DisplayAttribute>();

            return new DisplayAttributeValues(enumValue, displayAttribute);
        }

        public sealed class DisplayAttributeValues
        {
            private readonly Enum enumValue;
            private readonly DisplayAttribute displayAttribute;

            public DisplayAttributeValues(Enum enumValue, DisplayAttribute displayAttribute)
            {
                this.enumValue = enumValue;
                this.displayAttribute = displayAttribute;
            }

            public bool? AutoGenerateField => this.displayAttribute?.GetAutoGenerateField();
            public bool? AutoGenerateFilter => this.displayAttribute?.GetAutoGenerateFilter();
            public int? Order => this.displayAttribute?.GetOrder();
            public string Description => this.displayAttribute != null ? this.displayAttribute.GetDescription() : string.Empty;
            public string GroupName => this.displayAttribute != null ? this.displayAttribute.GetGroupName() : string.Empty;
            public string Name => this.displayAttribute != null ? this.displayAttribute.GetName() : this.enumValue.ToString();
            public string Prompt => this.displayAttribute != null ? this.displayAttribute.GetPrompt() : string.Empty;
            public string ShortName => this.displayAttribute != null ? this.displayAttribute.GetShortName() : this.enumValue.ToString();
        }
    }

you can also use this command :

wget --mirror -pc --convert-links -P ./your-local-dir/ http://www.your-website.com

so that you get the exact mirror of the website you want to download

My problem was I was creating the route first

// ...
router.get('/post/data', myController.postHandler);
// ...

and registering the middleware after the route

app.use(bodyParser.json());
//etc

due to app structure & copy and pasting the project together from examples.

Once I fixed the order to register middleware before the route, it all worked.

Actually the XSD is XML itself. Its purpose is to validate the structure of another XML document. The XSD is not mandatory for any XML, but it assures that the XML could be used for some particular purposes. The XML is only containing data in suitable format and structure.

You could use a Comparator with Java's built-in methods for sorting and binary search. Suppose you have a class like this, where a and b are the fields you want to use for sorting:

class Thing { String a, b, c, d; }

You would define your Comparator:

Comparator<Thing> comparator = new Comparator<Thing>() {
  public int compare(Thing o1, Thing o2) {
    if (o1.a.equals(o2.a)) {
      return o1.b.compareTo(o2.b);
    }
    return o1.a.compareTo(o2.a);
  }
};

Then sort your list:

Collections.sort(list, comparator);

And finally do the binary search:

int i = Collections.binarySearch(list, thingToFind, comparator);

You could try the following code. I can't vouch for browser compatibility though, so you'll have to test that.

function testImage(URL) {
    var tester=new Image();
    tester.onload=imageFound;
    tester.onerror=imageNotFound;
    tester.src=URL;
}

function imageFound() {
    alert('That image is found and loaded');
}

function imageNotFound() {
    alert('That image was not found.');
}

testImage("http://foo.com/bar.jpg");

And my sympathies for the jQuery-resistant boss!

To help guard against SQL injection, I normally try to use functions wherever possible. In this case, you could do:

...
SET @TableName = '<[db].><[schema].>tblEmployees'
SET @TableID   = OBJECT_ID(TableName) --won't resolve if malformed/injected.
...
SET @SQLQuery = 'SELECT * FROM ' + OBJECT_NAME(@TableID) + ' WHERE EmployeeID = @EmpID' 

Python 3 built-in exceptions have the strerror field:

except ValueError as err:
  err.strerror = "New error message"
  raise err

Simple version for Python 2.7+

my_ordered_dict = json.loads(json_str, object_pairs_hook=collections.OrderedDict)

Or for Python 2.4 to 2.6

import simplejson as json
import ordereddict

my_ordered_dict = json.loads(json_str, object_pairs_hook=ordereddict.OrderedDict)

Checking Permission Results

 @Override

    super.onRequestPermissionsResult(requestCode, permissions, grantResults);

    switch (requestCode) {
        case CAMERA_PERMISSION_REQUEST_CODE:
            if (grantResults.length > 0 && permissions[0].equals(Manifest.permission.CAMERA)) {
                // check whether camera permission granted or not.
                if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {

                }
            }
            break;
        case STORAGE_PERMISSION_REQUEST_CODE:
            if (grantResults.length > 0 && permissions[0].equals(Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
                // check whether storage permission granted or not.
                if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                    launchCamera();
                }
            }
            break;
        case MULTIPLE_PERMISSIONS:
            if (grantResults.length > 0 && permissions[0].equals(Manifest.permission.CAMERA) && permissions[1].equals(Manifest.permission.WRITE_EXTERNAL_STORAGE)) {

                    launchCamera();

                }
            }
            break;
        default:
            break;
    }
}

you can just copy and paste this code, it works fine. change context(this) & permissions according to you.

Depending on your URL scheme, you can make the UTF-8 encoded part "not important". For example, if you look at Stack Overflow URLs, they're of the following form:

http://stackoverflow.com/questions/2742852/unicode-characters-in-urls

However, the server doesn't actually care if you get the part after the identifier wrong, so this also works:

http://stackoverflow.com/questions/2742852/?????????????????

So if you had a layout like this, then you could potentially use UTF-8 in the part after the identifier and it wouldn't really matter if it got garbled. Of course this probably only works in somewhat specialised circumstances...

Scripts based on processing the list of installed plugins may not work as there are dependencies between installed plugins (e,g, cordova-plugin-file and cordova-plugin-file-transfer).

In the example, the script will find the file plugin first, then it will try to remove it and we'll get an error as file-transfer requires it. Therefore, we shall have

If anyone is getting this error using Nginx, try adding the following to your server config:

server {
    listen 443 ssl;
    ...
}

The issue stems from Nginx serving an HTTP server to a client expecting HTTPS on whatever port you're listening on. When you specify ssl in the listen directive, you clear this up on the server side.

That will almost work.

When pushing to a non-default branch, you need to specify the source ref and the target ref:

git push origin branch1:branch2

Or

git push <remote> <branch with new changes>:<branch you are pushing to> 

$('input[name="testing"]').val(theValue);

Try this out:

grep "Killed process" /var/log/syslog

There is no limit to the input of md5 that I know of. Some implementations require the entire input to be loaded into memory before passing it into the md5 function (i.e., the implementation acts on a block of memory, not on a stream), but this is not a limitation of the algorithm itself. The output is always 128 bits. Note that md5 is not an encryption algorithm, but a cryptographic hash. This means that you can use it to verify the integrity of a chunk of data, but you cannot reverse the hashing. Also note that md5 is considered broken, so you shouldn't use it for anything security-related (it's still fine to verify the integrity of downloaded files and such).

This is Microsoft's recommended way to handle WCF client calls:

For more detail see: Expected Exceptions

try
{
    ...
    double result = client.Add(value1, value2);
    ...
    client.Close();
}
catch (TimeoutException exception)
{
    Console.WriteLine("Got {0}", exception.GetType());
    client.Abort();
}
catch (CommunicationException exception)
{
    Console.WriteLine("Got {0}", exception.GetType());
    client.Abort();
}

Additional information So many people seem to be asking this question on WCF that Microsoft even created a dedicated sample to demonstrate how to handle exceptions:

c:\WF_WCF_Samples\WCF\Basic\Client\ExpectedExceptions\CS\client

Download the sample: C# or VB

Considering that there are so many issues involving the using statement, (heated?) Internal discussions and threads on this issue, I'm not going to waste my time trying to become a code cowboy and find a cleaner way. I'll just suck it up, and implement WCF clients this verbose (yet trusted) way for my server applications.

Optional Additional Failures to catch

Many exceptions derive from CommunicationException and I don't think most of those exceptions should be retried. I drudged through each exception on MSDN and found a short list of retry-able exceptions (in addition to TimeOutException above). Do let me know if I missed an exception that should be retried.

  // The following is typically thrown on the client when a channel is terminated due to the server closing the connection.
catch (ChannelTerminatedException cte)
{
secureSecretService.Abort();
// todo: Implement delay (backoff) and retry
}

// The following is thrown when a remote endpoint could not be found or reached.  The endpoint may not be found or 
// reachable because the remote endpoint is down, the remote endpoint is unreachable, or because the remote network is unreachable.
catch (EndpointNotFoundException enfe)
{
secureSecretService.Abort();
// todo: Implement delay (backoff) and retry
}

// The following exception that is thrown when a server is too busy to accept a message.
catch (ServerTooBusyException stbe)
{
secureSecretService.Abort();
// todo: Implement delay (backoff) and retry
}

Admittedly, this is a bit of mundane code to write. I currently prefer this answer, and don't see any "hacks" in that code that may cause issues down the road.

FIX FOR OSX EL CAPITAN

I'm still on OSX 10.11.6 with XCode 8.2.1 ... will upgrade someday but not today. I was able to get past the :CFBundleIdentifier error by downgrading react native to 52.0

yarn upgrade [email protected]

Got me a successful build on the simulator. Cheers!

If I understand you right, you can do this:

<img src="image.png" style="background-color:red;" />

In fact, you can even apply a whole background-image to the image, resulting in two "layers" without the need for multi-background support in the browser ;)

Like this (for MySQL):

SELECT IFNULL(MAX(X), 0) AS MaxX
FROM tbl
WHERE XID = 1

For MSSQL replace IFNULL with ISNULL or for Oracle use NVL

Okay, so I needed a solution to this, and I borrowed heavily from the answers to this question and made a library: https://github.com/rahuldottech/varDx (Licensed under the MIT license).

It uses serialize() and unserialize() and writes data to a file. It can read and write multiple objects/variables/whatever to and from the same file.

Usage:

<?php
require 'varDx.php';
$dx = new \varDx\cDX; //create an object
$dx->def('file.dat'); //define data file
$val1 = "this is a string";
$dx->write('data1', $val1); //writes key to file
echo $dx->read('data1'); //returns key value from file

See the github page for more information. It has functions to read, write, check, modify and delete data.

Based on the suggestion of using the PushbackInputStream, you'll find an exemple implementation here:

/**
 * @author Lorber Sebastien <i>([email protected])</i>
 */
public class NonEmptyInputStream extends FilterInputStream {

  /**
   * Once this stream has been created, do not consume the original InputStream 
   * because there will be one missing byte...
   * @param originalInputStream
   * @throws IOException
   * @throws EmptyInputStreamException
   */
  public NonEmptyInputStream(InputStream originalInputStream) throws IOException, EmptyInputStreamException {
    super( checkStreamIsNotEmpty(originalInputStream) );
  }


  /**
   * Permits to check the InputStream is empty or not
   * Please note that only the returned InputStream must be consummed.
   *
   * see:
   * http://stackoverflow.com/questions/1524299/how-can-i-check-if-an-inputstream-is-empty-without-reading-from-it
   *
   * @param inputStream
   * @return
   */
  private static InputStream checkStreamIsNotEmpty(InputStream inputStream) throws IOException, EmptyInputStreamException {
    Preconditions.checkArgument(inputStream != null,"The InputStream is mandatory");
    PushbackInputStream pushbackInputStream = new PushbackInputStream(inputStream);
    int b;
    b = pushbackInputStream.read();
    if ( b == -1 ) {
      throw new EmptyInputStreamException("No byte can be read from stream " + inputStream);
    }
    pushbackInputStream.unread(b);
    return pushbackInputStream;
  }

  public static class EmptyInputStreamException extends RuntimeException {
    public EmptyInputStreamException(String message) {
      super(message);
    }
  }

}

And here are some passing tests:

  @Test(expected = EmptyInputStreamException.class)
  public void test_check_empty_input_stream_raises_exception_for_empty_stream() throws IOException {
    InputStream emptyStream = new ByteArrayInputStream(new byte[0]);
    new NonEmptyInputStream(emptyStream);
  }

  @Test
  public void test_check_empty_input_stream_ok_for_non_empty_stream_and_returned_stream_can_be_consummed_fully() throws IOException {
    String streamContent = "HELLooooô wörld";
    InputStream inputStream = IOUtils.toInputStream(streamContent, StandardCharsets.UTF_8);
    inputStream = new NonEmptyInputStream(inputStream);
    assertThat(IOUtils.toString(inputStream,StandardCharsets.UTF_8)).isEqualTo(streamContent);
  }

ehh, its not a bug as one person mentioned. that is the expected behavior as the number of days in a month is often different. The easiest way to get the previous month using strtotime would probably be to use -1 month from the first of this month.

$date_string = date('Y-m', strtotime('-1 month', strtotime(date('Y-m-01'))));

Just set focusable property of your edittext to "false" and you are done.

<EditText
        android:id="@+id/EditTextInput"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:focusable="false"
        android:gravity="right"
        android:cursorVisible="true">
    </EditText>

Below options doesn't work

In code:

editText.setEnabled(false); Or, in XML: android:editable="false"

FYI this kind of code works (you can find it ugly, it is your right :) ) :

def list = null
list.each { println it }
soSomething()

In other words, this code has null/empty checks both useless:

if (members && !members.empty) {
    members.each { doAnotherThing it }
}

def doAnotherThing(def member) {
  // Some work
}

You can't install and run in one go - but you can certainly use adb to start your already installed application. Use adb shell am start to fire an intent - you will need to use the correct intent for your application though. A couple of examples:

adb shell am start -a android.intent.action.MAIN -n com.android.settings/.Settings 

will launch Settings, and

adb shell am start -a android.intent.action.MAIN -n com.android.browser/.BrowserActivity 

will launch the Browser. If you want to point the Browser at a particular page, do this

adb shell am start -a android.intent.action.VIEW -n com.android.browser/.BrowserActivity http://www.google.co.uk

If you don't know the name of the activities in the APK, then do this

aapt d xmltree <path to apk> AndroidManifest.xml

the output content will includes a section like this:

   E: activity (line=32)
    A: android:theme(0x01010000)=@0x7f080000
    A: android:label(0x01010001)=@0x7f070000
    A: android:name(0x01010003)="com.anonymous.MainWindow"
    A: android:launchMode(0x0101001d)=(type 0x10)0x3
    A: android:screenOrientation(0x0101001e)=(type 0x10)0x1

        XE: (line=34)

That tells you the name of the main activity (MainWindow), and you can now run

adb shell am start -a android.intent.action.MAIN -n com.anonymous/.MainWindow

The GIMP (GNU Image Manipulation Program). It's free, open source and runs on Windows and Linux (and maybe Mac?).

The ruby version 1.8.7 seems to be your system ruby.

Normally you can choose the ruby version you'd like, if you are using rvm with following. Simple change into your directory in a new terminal and type in:

rvm use 2.0.0

You can find more details about rvm here: http://rvm.io Open the website and scroll down, you will see a few helpful links. "Setting up default rubies" for example could help you.

Update: To set the ruby as default:

rvm use 2.0.0 --default

The most important difference is this:

• In case of persist method, if the entity that is to be managed in the persistence context, already exists in persistence context, the new one is ignored. (NOTHING happened)

• But in case of merge method, the entity that is already managed in persistence context will be replaced by the new entity (updated) and a copy of this updated entity will return back. (from now on any changes should be made on this returned entity if you want to reflect your changes in persistence context)

headers were not working for me on my shared hosting, reason was i was using my hotmail email address in header. i created a email on my cpanel and i set that same email in the header yeah it worked like a charm!

 $header = 'From: ShopFive <[email protected]>' . "\r\n";

With urlsearchparams:

const params = new URLSearchParams()
params.append('imageurl', http://www.image.com/?username=unknown&password=unknown)
return `http://www.foobar.com/foo?${params.toString()}`

I think that you could use a POST or PATCH method to handle this since they typically design for this.

• Using a POST method is typically used to add an element when used on list resource but you can also support several actions for this method. See this answer: How to Update a REST Resource Collection. You can also support different representation formats for the input (if they correspond to an array or a single elements).

  In the case, it's not necessary to define your format to describe the update.

• Using a PATCH method is also suitable since corresponding requests correspond to a partial update. According to RFC5789 (http://tools.ietf.org/html/rfc5789):

  Several applications extending the Hypertext Transfer Protocol (HTTP) require a feature to do partial resource modification. The existing HTTP PUT method only allows a complete replacement of a document. This proposal adds a new HTTP method, PATCH, to modify an existing HTTP resource.

  In the case, you have to define your format to describe the partial update.

I think that in this case, POST and PATCH are quite similar since you don't really need to describe the operation to do for each element. I would say that it depends on the format of the representation to send.

The case of PUT is a bit less clear. In fact, when using a method PUT, you should provide the whole list. As a matter of fact, the provided representation in the request will be in replacement of the list resource one.

You can have two options regarding the resource paths.

• Using the resource path for doc list

In this case, you need to explicitely provide the link of docs with a binder in the representation you provide in the request.

Here is a sample route for this /docs.

The content of such approach could be for method POST:

[
    { "doc_number": 1, "binder": 4, (other fields in the case of creation) },
    { "doc_number": 2, "binder": 4, (other fields in the case of creation) },
    { "doc_number": 3, "binder": 5, (other fields in the case of creation) },
    (...)
]

• Using sub resource path of binder element

In addition you could also consider to leverage sub routes to describe the link between docs and binders. The hints regarding the association between a doc and a binder doesn't have now to be specified within the request content.

Here is a sample route for this /binder/{binderId}/docs. In this case, sending a list of docs with a method POST or PATCH will attach docs to the binder with identifier binderId after having created the doc if it doesn't exist.

The content of such approach could be for method POST:

[
    { "doc_number": 1, (other fields in the case of creation) },
    { "doc_number": 2, (other fields in the case of creation) },
    { "doc_number": 3, (other fields in the case of creation) },
    (...)
]

Regarding the response, it's up to you to define the level of response and the errors to return. I see two levels: the status level (global level) and the payload level (thinner level). It's also up to you to define if all the inserts / updates corresponding to your request must be atomic or not.

• Atomic

In this case, you can leverage the HTTP status. If everything goes well, you get a status 200. If not, another status like 400 if the provided data aren't correct (for example binder id not valid) or something else.

• Non atomic

In this case, a status 200 will be returned and it's up to the response representation to describe what was done and where errors eventually occur. ElasticSearch has an endpoint in its REST API for bulk update. This could give you some ideas at this level: http://www.elasticsearch.org/guide/en/elasticsearch/guide/current/bulk.html.

• Asynchronous

You can also implement an asynchronous processing to handle the provided data. In this case, the HTTP status returns will be 202. The client needs to pull an additional resource to see what happens.

Before finishing, I also would want to notice that the OData specification addresses the issue regarding relations between entities with the feature named navigation links. Perhaps could you have a look at this ;-)

This is the simplest example of function pointers and function pointer arrays that I wrote as an exercise.

    typedef double (*pf)(double x);  /*this defines a type pf */

    double f1(double x) { return(x+x);}
    double f2(double x) { return(x*x);}

    pf pa[] = {f1, f2};


    main()
    {
        pf p;

        p = pa[0];
        printf("%f\n", p(3.0));
        p = pa[1];
        printf("%f\n", p(3.0));
    }

I don't seem to have enough rep to close this as a duplicate, but it is one if someone else can do that. I posted the same thing over at A more pretty/informative Var_dump alternative in PHP? but for the sake of saving time, I'll copy/paste it here too:

I had to add another answer here because I didn't really want to go through the steps in the other solutions. It is extremely simple and requires no extensions, includes etc and is what I prefer. It's very easy and very fast.

First just json_encode the variable in question:

echo json_encode($theResult);

Copy the result you get into the JSON Editor at http://jsoneditoronline.org/ just copy it into the left side pane, click Copy > and it pretty prints the JSON in a really nice tree format.

To each their own, but hopefully this helps some others have one more nice option! :)

All the others have already mentioned the use of the scripting.runtime version of the Dictionary class. If you are unable to use this DLL you can also use this version, simply add it to your code.

https://github.com/VBA-tools/VBA-Dictionary/blob/master/Dictionary.cls

It is identical to Microsoft's version.

If you want to turn off the warnings about the specific strings, you can use the following:

strings.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>    

    <!--suppress MissingTranslation -->
    <string name="some_string">ignore my translation</string>
    ...

</resources>

If you want to warn on specific strings instead of an error, you will need to build a custom Lint rule to adjust the severity status for a specific thing.

http://tools.android.com/tips/lint-custom-rules

Do not use WP_Query() or get_posts(). From the WooCommerce doc:

wc_get_products and WC_Product_Query provide a standard way of retrieving products that is safe to use and will not break due to database changes in future WooCommerce versions. Building custom WP_Queries or database queries is likely to break your code in future versions of WooCommerce as data moves towards custom tables for better performance.

You can retrieve the products you want like this:

$args = array(
    'category' => array( 'hoodies' ),
    'orderby'  => 'name',
);
$products = wc_get_products( $args );

WooCommerce documentation

Note: the category argument takes an array of slugs, not IDs.

You'll want to use the specified market protocol:

final String appPackageName = "com.example"; // Can also use getPackageName(), as below
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + appPackageName)));

Keep in mind, this will crash on any device that does not have the Market installed (the emulator, for example). Hence, I would suggest something like:

final String appPackageName = getPackageName(); // getPackageName() from Context or Activity object
try {
    startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + appPackageName)));
} catch (android.content.ActivityNotFoundException anfe) {
    startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://play.google.com/store/apps/details?id=" + appPackageName)));
}

While using getPackageName() from Context or subclass thereof for consistency (thanks @cprcrack!). You can find more on Market Intents here: link.

Do it through the way Android Studio provided to you

Right click on the res folder and add your image as Image Assets in this way. Android studio will automatically generate image assets with different resolutions.

You can directly create the folder and drag image inside but you won't have the different sized icons if you do that.

Looks like you forgot the mode parameter when calling open, try w:

file = open("copy.txt", "w") 
file.write("Your text goes here") 
file.close() 

The default value is r and will fail if the file does not exist

'r' open for reading (default)
'w' open for writing, truncating the file first

Other interesting options are

'x' open for exclusive creation, failing if the file already exists
'a' open for writing, appending to the end of the file if it exists

See Doc for Python2.7 or Python3.6

-- EDIT --

As stated by chepner in the comment below, it is better practice to do it with a withstatement (it guarantees that the file will be closed)

with open("copy.txt", "w") as file:
    file.write("Your text goes here")

\xampp\apache\logs\error.log is the default location of error logs in php.

No.. It is not proper way. Refer the steps,

For Classpath reference: Right click on project in Eclipse -> Buildpath -> Configure Build path -> Java Build Path (left Pane) -> Libraries(Tab) -> Add External Jars -> Select your jar and select OK.

For Deployment Assembly: Right click on WAR in eclipse-> Buildpath -> Configure Build path -> Deployment Assembly (left Pane) -> Add -> External file system -> Add -> Select your jar -> Add -> Finish.

This is the proper way! Don't forget to remove environment variable. It is not required now.

Try this. Surely it will work. Try to use Maven, it will simplify you task.

@lockwobr Thanks for update

This does not work 100% of the time in api version 16, if you read the code on github the function "currentActivityThread" was change in Kitkat, so I want to say version 19ish, kind of hard to match api version to releases in github.

Having access to the current Activity is very handy. Wouldn’t it be nice to have a static getActivity method returning the current Activity with no unnecessary questions?

The Activity class is very useful. It gives access to the application’s UI thread, views, resources, and many more. Numerous methods require a Context, but how to get the pointer? Here are some ways:

• Tracking the application’s state using overridden lifecycle methods. You have to store the current Activity in a static variable and you need access to the code of all Activities.
• Tracking the application’s state using Instrumentation. Declare Instrumentation in the manifest, implement it and use its methods to track Activity changes. Passing an Activity pointer to methods and classes used in your Activities. Injecting the pointer using one of the code injection libraries. All of these approaches are rather inconvenient; fortunately, there is a much easier way to get the current Activity.
• Seems like the system needs access to all Activities without the issues mentioned above. So, most likely there is a way to get Activities using only static calls. I spent a lot of time digging through the Android sources on grepcode.com, and I found what I was looking for. There is a class called ActivityThread. This class has access to all Activities and, what’s even better, has a static method for getting the current ActivityThread. There is only one little problem – the Activity list has package access.

Easy to solve using reflection:

public static Activity getActivity() {
    Class activityThreadClass = Class.forName("android.app.ActivityThread");
    Object activityThread = activityThreadClass.getMethod("currentActivityThread").invoke(null);
    Field activitiesField = activityThreadClass.getDeclaredField("mActivities");
    activitiesField.setAccessible(true);

    Map<Object, Object> activities = (Map<Object, Object>) activitiesField.get(activityThread);
    if (activities == null)
        return null;

    for (Object activityRecord : activities.values()) {
        Class activityRecordClass = activityRecord.getClass();
        Field pausedField = activityRecordClass.getDeclaredField("paused");
        pausedField.setAccessible(true);
        if (!pausedField.getBoolean(activityRecord)) {
            Field activityField = activityRecordClass.getDeclaredField("activity");
            activityField.setAccessible(true);
            Activity activity = (Activity) activityField.get(activityRecord);
            return activity;
        }
    }

    return null;
}

Such a method can be used anywhere in the app and it’s much more convenient than all of the mentioned approaches. Moreover, it seems like it’s not as unsafe as it looks. It doesn’t introduce any new potential leaks or null pointers.

The above code snippet lacks exception handling and naively assumes that the first running Activity is the one we’re looking for. You might want to add some additional checks.

1. VARCHAR can store up to 2000 bytes of characters while VARCHAR2 can store up to 4000 bytes of characters.

2. If we declare datatype as VARCHAR then it will occupy space for NULL values. In the case of VARCHAR2 datatype, it will not occupy any space for NULL values. e.g.,

   name varchar(10)

will reserve 6 bytes of memory even if the name is 'Ravi__', whereas

name varchar2(10) 

will reserve space according to the length of the input string. e.g., 4 bytes of memory for 'Ravi__'.

Here, _ represents NULL.

NOTE: varchar will reserve space for null values and varchar2 will not reserve any space for null values.

Reference the DLL´s to your Resources and and use the AssemblyResolve-Event to return the Resource-DLL.

public partial class App : Application
{
    public App()
    {
        AppDomain.CurrentDomain.AssemblyResolve += (sender, args) =>
        {

            Assembly thisAssembly = Assembly.GetExecutingAssembly();

            //Get the Name of the AssemblyFile
            var name = args.Name.Substring(0, args.Name.IndexOf(',')) + ".dll";

            //Load form Embedded Resources - This Function is not called if the Assembly is in the Application Folder
            var resources = thisAssembly.GetManifestResourceNames().Where(s => s.EndsWith(name));
            if (resources.Count() > 0)
            {
                var resourceName = resources.First();
                using (Stream stream = thisAssembly.GetManifestResourceStream(resourceName))
                {
                    if (stream == null) return null;
                    var block = new byte[stream.Length];
                    stream.Read(block, 0, block.Length);
                    return Assembly.Load(block);
                }
            }
            return null;
        };
    }
}

ARIA (Accessible Rich Internet Applications) defines a way to make Web content and Web applications more accessible to people with disabilities.

The hidden attribute is new in HTML5 and tells browsers not to display the element. The aria-hidden property tells screen-readers if they should ignore the element. Have a look at the w3 docs for more details:

https://www.w3.org/WAI/PF/aria/states_and_properties#aria-hidden

Using these standards can make it easier for disabled people to use the web.

Having tried everything, I finally came up with a solution.

Just place the following in your template:

{{currentDirective.attr = parentDirective.attr; ''}}

It just writes the parent scope attribute/variable you want to access to the current scope.

Also notice the ; '' at the end of the statement, it's to make sure there's no output in your template. (Angular evaluates every statement, but only outputs the last one).

It's a bit hacky, but after a few hours of trial and error, it does the job.

if you are looking to do it via code on specific conditions, here is the solution worked for me. I have used in middleware to block certain users: these lines from below is the actual code to logout:

$auth = new LoginController();
$auth->logout($request);

Complete File:

namespace App\Http\Middleware;
use Closure;
use Auth;
use App\Http\Controllers\Auth\LoginController;
class ExcludeCustomers{
    public function handle($request, Closure $next){
        $user = Auth::guard()->user();
        if( $user->role == 3 ) {
            $auth = new LoginController();
            $auth->logout($request);
            header("Location: https://google.com");
            die();
        } 
        return $next($request);
    }
}

For people coming here from Google looking for a fast way to downsample images in numpy arrays for use in Machine Learning applications, here's a super fast method (adapted from here ). This method only works when the input dimensions are a multiple of the output dimensions.

The following examples downsample from 128x128 to 64x64 (this can be easily changed).

Channels last ordering

# large image is shape (128, 128, 3)
# small image is shape (64, 64, 3)
input_size = 128
output_size = 64
bin_size = input_size // output_size
small_image = large_image.reshape((output_size, bin_size, 
                                   output_size, bin_size, 3)).max(3).max(1)

Channels first ordering

# large image is shape (3, 128, 128)
# small image is shape (3, 64, 64)
input_size = 128
output_size = 64
bin_size = input_size // output_size
small_image = large_image.reshape((3, output_size, bin_size, 
                                      output_size, bin_size)).max(4).max(2)

For grayscale images just change the 3 to a 1 like this:

Channels first ordering

# large image is shape (1, 128, 128)
# small image is shape (1, 64, 64)
input_size = 128
output_size = 64
bin_size = input_size // output_size
small_image = large_image.reshape((1, output_size, bin_size,
                                      output_size, bin_size)).max(4).max(2)

This method uses the equivalent of max pooling. It's the fastest way to do this that I've found.

Sounds like an lxml advertisement in here. ;) ElementTree is included in the std library. Under 2.6 and below its xpath is pretty weak, but in 2.7+ much improved:

import xml.etree.ElementTree as ET
root = ET.parse(filename)
result = ''

for elem in root.findall('.//child/grandchild'):
    # How to make decisions based on attributes even in 2.6:
    if elem.attrib.get('name') == 'foo':
        result = elem.text
        break

This is an improvement to Eric's answer:

UIViewController *_topMostController(UIViewController *cont) {
    UIViewController *topController = cont;

    while (topController.presentedViewController) {
        topController = topController.presentedViewController;
    }

    if ([topController isKindOfClass:[UINavigationController class]]) {
        UIViewController *visible = ((UINavigationController *)topController).visibleViewController;
        if (visible) {
            topController = visible;
        }
    }

    return (topController != cont ? topController : nil);
}

UIViewController *topMostController() {
    UIViewController *topController = [UIApplication sharedApplication].keyWindow.rootViewController;

    UIViewController *next = nil;

    while ((next = _topMostController(topController)) != nil) {
        topController = next;
    }

    return topController;
}

_topMostController(UIViewController *cont) is a helper function.

Now all you need to do is call topMostController() and the top most UIViewController should be returned!

I'd recomment using good old javascript:

document.getElementById("addRunner").reset();

You can't use variable names to bind columns or other system objects, you need dynamic sql

DECLARE @value varchar(10)  
SET @value = 'intStep'  
DECLARE @sqlText nvarchar(1000); 

SET @sqlText = N'SELECT ' + @value + ' FROM dbo.tblBatchDetail'
Exec (@sqlText)

If Python3 is your cup of tea, you can do this (but please explain why you would?):

ls -1 | python -c "import sys; print(','.join(sys.stdin.read().splitlines()))"

The Swift version from String to Data and back to String:

Xcode 10.1 • Swift 4.2.1

extension Data {
    var string: String? {
        return String(data: self, encoding: .utf8)
    }
}

extension StringProtocol {
    var data: Data {
        return Data(utf8)
    }
}

extension String {
    var base64Decoded: Data? {
        return Data(base64Encoded: self)
    }
}

Playground

let string = "Hello World"                                  // "Hello World"
let stringData = string.data                                // 11 bytes
let base64EncodedString = stringData.base64EncodedString()  // "SGVsbG8gV29ybGQ="
let stringFromData = stringData.string                      // "Hello World"

let base64String = "SGVsbG8gV29ybGQ="
if let data = base64String.base64Decoded {
    print(data)                                    //  11 bytes
    print(data.base64EncodedString())              // "SGVsbG8gV29ybGQ="
    print(data.string ?? "nil")                    // "Hello World"
}

let stringWithAccent = "Olá Mundo"                          // "Olá Mundo"
print(stringWithAccent.count)                               // "9"
let stringWithAccentData = stringWithAccent.data            // "10 bytes" note: an extra byte for the acute accent
let stringWithAccentFromData = stringWithAccentData.string  // "Olá Mundo\n"

Zeep is a decent SOAP library for Python that matches what you're asking for: http://docs.python-zeep.org

It is called an interface. Many OO languages have this feature. You might want to read through the php explanation here: http://de2.php.net/interface

<script type = "text/javascript">
function get_values(input_id)
{
var input = document.getElementById(input_id).value;
document.write(input);
}
</script>

<!--Insert more code here-->


<input type = "text" id = "textfield">
<input type = "button" onclick = "get('textfield')" value = "submit">

Next time you ask a question here, include more detail and what you have tried.

(?<![\w\d])abc(?![\w\d])

this makes sure that your match is not preceded by some character, number, or underscore and is not followed immediately by character or number, or underscore

so it will match "abc" in "abc", "abc.", "abc ", but not "4abc", nor "abcde"

Header names are not case sensitive.

From RFC 2616 - "Hypertext Transfer Protocol -- HTTP/1.1", Section 4.2, "Message Headers":

Each header field consists of a name followed by a colon (":") and the field value. Field names are case-insensitive.

The updating RFC 7230 does not list any changes from RFC 2616 at this part.

Alternatively (I'd say preferably), you can do it like this:

$(function () {
  $("div.class, div.secondclass").click(function(){
    //Doo something
  });
});

You can just use Lombok with access level PRIVATE in @NoArgsConstructor annotation to avoid unnecessary initialization.

@NoArgsConstructor(access = AccessLevel.PRIVATE)

public class FilePathHelper {

// your code

}

The key is to use "Content-Type": "text/plain" as mentioned by @MadhuBhat.

axios.post(path, code, { headers: { "Content-Type": "text/plain" } }).then(response => {
    console.log(response);
});

A thing to note if you use .NET is that a raw string to a controller will return 415 Unsupported Media Type. To get around this you need to encapsulate the raw string in hyphens like this and send it as "Content-Type": "application/json":

axios.post(path, "\"" + code + "\"", { headers: { "Content-Type": "application/json" } }).then(response => {
    console.log(response);
});

C# Controller:

[HttpPost]
public async Task<ActionResult<string>> Post([FromBody] string code)
{
    return Ok(code);
}

You can also make a POST with query params if that helps:

.post(`/mails/users/sendVerificationMail`, null, { params: {
  mail,
  firstname
}})
.then(response => response.status)
.catch(err => console.warn(err));

This will POST an empty body with the two query params:

POST http://localhost:8000/api/mails/users/sendVerificationMail?mail=lol%40lol.com&firstname=myFirstName

This answer really helped me get started (noob) - but I encountered some weird behavior when I set a start date of 12/31/2014 and added +1 to default the end date. Instead of giving me an end date of 01/01/2015 I was getting 02/01/2015 (!!!). This version parses the components of the start date to avoid these end of year oddities.

 $( "#date_start" ).datepicker({

   minDate: 0,
   dateFormat: "mm/dd/yy",

   onSelect: function(selected) {
         $("#date_end").datepicker("option","minDate", selected); //  mindate on the End datepicker cannot be less than start date already selected.
         var date = $(this).datepicker('getDate');
         var tempStartDate = new Date(date);
         var default_end = new Date(tempStartDate.getFullYear(), tempStartDate.getMonth(), tempStartDate.getDate()+1); //this parses date to overcome new year date weirdness
         $('#date_end').datepicker('setDate', default_end); // Set as default                           
   }

 });

 $( "#date_end" ).datepicker({

   minDate: 0,
   dateFormat: "mm/dd/yy",

   onSelect: function(selected) {
     $("#date_start").datepicker("option","maxDate", selected); //  maxdate on the Start datepicker cannot be more than end date selected.

  }

});

If you are looking for the actual row that you just inserted with Laravel 3 and 4 when you perform a save or create action on a new model like:

$user->save();

-or-

$user = User::create(array('email' => '[email protected]'));

then the inserted model instance will be returned and can be used for further action such as redirecting to the profile page of the user just created.

Looking for the last inserted record works on low volume system will work almost all of the time but if you ever have to inserts go in at the same time you can end up querying to find the wrong record. This can really become a problem in a transactional system where multiple tables need updated.

If you use CURLOPT_COOKIE_FILE and CURLOPT_COOKIE_JAR curl will read/write the cookies from/to a file. You can, after curl is done with it, read and/or modify it however you want.

StringUtils.abbreviate("abcdefg", 6);

This will give you the following result: abc...

Where 6 is the needed length, and "abcdefg" is the string that needs to be abbrevieted.

Why not doing it in two lines?

var a, b, c, d;    // All in the same scope
a = b = c = d = 1; // Set value to all.

The reason why, is to preserve the local scope on variable declarations, as this:

var a = b = c = d = 1;

will lead to the implicit declarations of b, c and d on the window scope.

Using Google's Gson

Why not use Google's Gson as mentioned in here?

Very straight forward and did the job for me:

HashMap<String,String> map = new Gson().fromJson( yourJsonString, new TypeToken<HashMap<String, String>>(){}.getType());

This may help if it is the same problem I had. Trying to use ng serve and ng build --watch sometimes worked but mostly they were not watching for code changes and I thought it was something to do with ng.

Then I remembered a problem I had a while back with inotify watches

I ran this on my Ubuntu machine and it seems to have kicked in and watching code changes:

echo fs.inotify.max_user_watches=524288 | sudo tee /etc/sysctl.d/40-max-user-watches.conf && sudo sysctl --system

grep will print any lines matching the pattern you provide. If you only want to print the part of the line that matches the pattern, you can pass the -o option:

-o, --only-matching Print only the matched (non-empty) parts of a matching line, with each such part on a separate output line.

Like this:

echo 'Here is a line mentioning 99% somewhere' | grep -o '[0-9]+'

If you want your result concatenated, as you show in your question, you could try something like:

>>> reduce(lambda x, y: str(x)+str(y), map(ord,"hello world"))
'10410110810811132119111114108100'

The reason i could not delete some of the users via 'drop' statement was that there is a bug in Mysql http://bugs.mysql.com/bug.php?id=62255 with hostname containing upper case letters. The solution was running following query:

DELETE FROM mysql.user where host='Some_Host_With_UpperCase_Letters';

I am still trying to figure the other issue where the root user with all permissions are unable to grant privileges to new user for particular database

This is the way:

kill -9 $(pgrep -d' ' -f chrome)

This is a small tweak on the other answers. If you have nested divs you can include more exciting content such as H1s in your popup.

CSS

div.appear {
    width: 250px; 
    border: #000 2px solid;
    background:#F8F8F8;
    position: relative;
    top: 5px;
    left:15px;
    display:none;
    padding: 0 20px 20px 20px;
    z-index: 1000000;
}
div.hover  {
    cursor:pointer;
    width: 5px;
}
div.hover:hover div.appear {
    display:block;
}

HTML

<div class="hover">
<img src="questionmark.png"/>
    <div class="appear">
       <h1>My popup</h1>Hitherto and whenceforth.
    </div>
</div>

The problem with these solutions is that everything after this in the page gets shifted when the popup is displayed, ie, the rest of the page jumps downwards to 'make space'. The only way I could fix this was by making position:absolute and removing the top and left CSS tags.

This works for me:

git pull origin <sha>

e.g.

[dbn src]$ git fetch
[dbn src]$ git status
On branch current_feature
Your branch and 'origin/master' have diverged,
and have 2 and 7 different commits each, respectively.
...
[dbn src]$ git log -3 --pretty=oneline origin/master
f4d10ad2a5eda447bea53fed0b421106dbecea66 CASE-ID1: some descriptive msg
28eb00a42e682e32bdc92e5753a4a9c315f62b42 CASE-ID2: I'm so good at writing commit titles
ff39e46b18a66b21bc1eed81a0974e5c7de6a3e5 CASE-ID2: woooooo
[dbn src]$ git pull origin 28eb00a42e682e32bdc92e5753a4a9c315f62b42
[dbn src]$ git status
On branch current_feature
Your branch and 'origin/master' have diverged,
and have 2 and 1 different commits each, respectively.
...

This pulls 28eb00, ff39e4, and everything before, but doesn't pull f4d10ad. It allows the use of pull --rebase, and honors pull settings in your gitconfig. This works because you're basically treating 28eb00 as a branch.

For the version of git that I'm using, this method requires a full commit hash - no abbreviations or aliases are allowed. You could do something like:

[dbn src]$ git pull origin `git rev-parse origin/master^`

Here's an example:

char myChar = '|';
string myString = "||";

Chars are delimited by single quotes, and strings by double quotes.

The good news is C# switch statements work with strings!

switch (mytoken)
{
    case "==":
        //Something here.
        break;
    default:
        //Handle when no token is found.
        break;
}

// Converting String in to Double

double doubleValue = [yourString doubleValue];

// Converting Double in to String
NSString *yourString = [NSString stringWithFormat:@"%.20f", doubleValue];
// .20f takes the value up to 20 position after decimal

// Converting double to int

int intValue = (int) doubleValue;
or
int intValue = [yourString intValue];

Once changes has been committed it will not be able to delete. because commit's basic nature is not to delete.

Thing you can do (easy and safe method),

Interactive Rebase:

1) git rebase -i HEAD~2 #will show your recent 2 commits

2) Your commit will list like , Recent will appear at the bottom of the page LILO(last in Last Out)

Delete the last commit row entirely

3) save it by ctrl+X or ESC:wq

now your branch will updated without your last commit..

Fast way to get External ip without any connection Actualy no need any Http connection for that

first you must add NATUPNPLib.dll on Referance And select it from referances and check from properties window Embed Interop Type to False

using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using NATUPNPLib; // Add this dll from referance and chande Embed Interop Interop to false from properties panel on visual studio
using System.Net;

namespace Client
{
    class NATTRAVERSAL
    {
        //This is code for get external ip
        private void NAT_TRAVERSAL_ACT()
        {
            UPnPNATClass uPnP = new UPnPNATClass();
            IStaticPortMappingCollection map = uPnP.StaticPortMappingCollection;

            foreach (IStaticPortMapping item in map)
            {
                    Debug.Print(item.ExternalIPAddress); //This line will give you external ip as string
                    break;
            }
        }
    }
}

You can also use:

.rhead {
    width:300px;
}

but this will only with with some browsers, if I remember correctly IE8 does not allow this. Over all, It is safer to just put the width="" attribute in the <td> itself.

This flatten_nlevel function calls recursively the nested list1 to covert to one level. Try this out

def flatten_nlevel(list1, flat_list):
    for sublist in list1:
        if isinstance(sublist, type(list)):        
            flatten_nlevel(sublist, flat_list)
        else:
            flat_list.append(sublist)

list1 = [1,[1,[2,3,[4,6]],4],5]

items = []
flatten_nlevel(list1,items)
print(items)

output:

[1, 1, 2, 3, 4, 6, 4, 5]

Tablets supports tvdpi and for that scaling factor is 1.33 times dimensions of medium dpi

    ldpi | mdpi | tvdpi | hdpi | xhdpi | xxhdpi | xxxhdpi
    0.75 | 1    | 1.33  | 1.5  | 2     | 3      | 4

This means that if you generate a 400x400 image for xxxhdpi devices, you should generate the same resource in 300x300 for xxhdpi, 200x200 for xhdpi, 133x133 for tvdpi, 150x150 for hdpi, 100x100 for mdpi, and 75x75 for ldpi devices

John Resig, author of jQuery, submitted his version of cross-browser implementation of addEvent and removeEvent to circumvent compatibility issues with IE's improper or non-existent addEventListener.

function addEvent( obj, type, fn ) {
  if ( obj.attachEvent ) {
    obj['e'+type+fn] = fn;
    obj[type+fn] = function(){obj['e'+type+fn]( window.event );}
    obj.attachEvent( 'on'+type, obj[type+fn] );
  } else
    obj.addEventListener( type, fn, false );
}
function removeEvent( obj, type, fn ) {
  if ( obj.detachEvent ) {
    obj.detachEvent( 'on'+type, obj[type+fn] );
    obj[type+fn] = null;
  } else
    obj.removeEventListener( type, fn, false );
}

Here's Swift 3:

    if let htmlFile = Bundle.main.path(forResource: "aa", ofType: "html"){
        do{
            let htmlString = try NSString(contentsOfFile: htmlFile, encoding:String.Encoding.utf8.rawValue )
            messageWebView.loadHTMLString(htmlString as String, baseURL: nil)
        }
        catch _ {
        }
    }

This is because of a higher JDK during compile time and lower JDK during runtime. So you just need to update your JDK version, possible to JDK 7

Here is a real world example: Fixed point multiplies on old compilers.

These don't only come handy on devices without floating point, they shine when it comes to precision as they give you 32 bits of precision with a predictable error (float only has 23 bit and it's harder to predict precision loss). i.e. uniform absolute precision over the entire range, instead of close-to-uniform relative precision (float).

Modern compilers optimize this fixed-point example nicely, so for more modern examples that still need compiler-specific code, see

• Getting the high part of 64 bit integer multiplication: A portable version using uint64_t for 32x32 => 64-bit multiplies fails to optimize on a 64-bit CPU, so you need intrinsics or __int128 for efficient code on 64-bit systems.
• _umul128 on Windows 32 bits: MSVC doesn't always do a good job when multiplying 32-bit integers cast to 64, so intrinsics helped a lot.

C doesn't have a full-multiplication operator (2N-bit result from N-bit inputs). The usual way to express it in C is to cast the inputs to the wider type and hope the compiler recognizes that the upper bits of the inputs aren't interesting:

// on a 32-bit machine, int can hold 32-bit fixed-point integers.
int inline FixedPointMul (int a, int b)
{
  long long a_long = a; // cast to 64 bit.

  long long product = a_long * b; // perform multiplication

  return (int) (product >> 16);  // shift by the fixed point bias
}

The problem with this code is that we do something that can't be directly expressed in the C-language. We want to multiply two 32 bit numbers and get a 64 bit result of which we return the middle 32 bit. However, in C this multiply does not exist. All you can do is to promote the integers to 64 bit and do a 64*64 = 64 multiply.

x86 (and ARM, MIPS and others) can however do the multiply in a single instruction. Some compilers used to ignore this fact and generate code that calls a runtime library function to do the multiply. The shift by 16 is also often done by a library routine (also the x86 can do such shifts).

So we're left with one or two library calls just for a multiply. This has serious consequences. Not only is the shift slower, registers must be preserved across the function calls and it does not help inlining and code-unrolling either.

If you rewrite the same code in (inline) assembler you can gain a significant speed boost.

In addition to this: using ASM is not the best way to solve the problem. Most compilers allow you to use some assembler instructions in intrinsic form if you can't express them in C. The VS.NET2008 compiler for example exposes the 32*32=64 bit mul as __emul and the 64 bit shift as __ll_rshift.

Using intrinsics you can rewrite the function in a way that the C-compiler has a chance to understand what's going on. This allows the code to be inlined, register allocated, common subexpression elimination and constant propagation can be done as well. You'll get a huge performance improvement over the hand-written assembler code that way.

For reference: The end-result for the fixed-point mul for the VS.NET compiler is:

int inline FixedPointMul (int a, int b)
{
    return (int) __ll_rshift(__emul(a,b),16);
}

The performance difference of fixed point divides is even bigger. I had improvements up to factor 10 for division heavy fixed point code by writing a couple of asm-lines.

Using Visual C++ 2013 gives the same assembly code for both ways.

gcc4.1 from 2007 also optimizes the pure C version nicely. (The Godbolt compiler explorer doesn't have any earlier versions of gcc installed, but presumably even older GCC versions could do this without intrinsics.)

See source + asm for x86 (32-bit) and ARM on the Godbolt compiler explorer. (Unfortunately it doesn't have any compilers old enough to produce bad code from the simple pure C version.)

Modern CPUs can do things C doesn't have operators for at all, like popcnt or bit-scan to find the first or last set bit. (POSIX has a ffs() function, but its semantics don't match x86 bsf / bsr. See https://en.wikipedia.org/wiki/Find_first_set).

Some compilers can sometimes recognize a loop that counts the number of set bits in an integer and compile it to a popcnt instruction (if enabled at compile time), but it's much more reliable to use __builtin_popcnt in GNU C, or on x86 if you're only targeting hardware with SSE4.2: _mm_popcnt_u32 from <immintrin.h>.

Or in C++, assign to a std::bitset<32> and use .count(). (This is a case where the language has found a way to portably expose an optimized implementation of popcount through the standard library, in a way that will always compile to something correct, and can take advantage of whatever the target supports.) See also https://en.wikipedia.org/wiki/Hamming_weight#Language_support.

Similarly, ntohl can compile to bswap (x86 32-bit byte swap for endian conversion) on some C implementations that have it.

Another major area for intrinsics or hand-written asm is manual vectorization with SIMD instructions. Compilers are not bad with simple loops like dst[i] += src[i] * 10.0;, but often do badly or don't auto-vectorize at all when things get more complicated. For example, you're unlikely to get anything like How to implement atoi using SIMD? generated automatically by the compiler from scalar code.

Step 1

Step 4

Final Step

You should use List or array instead

List<Integer> list = new ArrayList<Integer>();
list.add(1);
list.add(2);
list.add(3);

Or

int[] arr  = new int[10];
arr[0]=1;
arr[1]=2;

Or even better

Map<String, Integer> map = new HashMap<String, Integer>();
map.put("n1", 1);
map.put("n2", 2);

//conditionally get 
map.get("n1");
