It sounds like you're using Subclipse; is that correct? If so, there's a great list of decorators and their descriptions at this answer by Tim Stone.

Here's the relevant snippet for your case:

- A file not under version control. These are typically new files that you have not committed to the repository yet.
- A file with no local changes.

Usually when I want to pass arguments to an alias in Bash, I use a combination of an alias and a function like this, for instance:

function __t2d {                                                                
         if [ "$1x" != 'x' ]; then                                              
            date -d "@$1"                                                       
         fi                                                                     
} 

alias t2d='__t2d'                                                               

process.cwd() returns the current working directory,

i.e. the directory from which you invoked the node command.

__dirname returns the directory name of the directory containing the JavaScript source code file

You can met another way to get time in seconds/milliseconds since 1 Jan 1970:

var milliseconds = +new Date;        
var seconds = milliseconds / 1000;

But be careful with such approach, cause it might be tricky to read and understand it.

Always remember that in case of checked exception you can catch only after throwing the exception(either you throw or any inbuilt method used in your code can throw) ,but in case of unchecked exception You an catch even when you have not thrown that exception.

Add jquery-2.1.0.min.js file

<script src="https://code.jquery.com/jquery-2.1.0.min.js"></script>

Write the codes given below:

<script>
$(document).ready(function () {   
    $("#checkAll").change(function() {
        var checked = $(this).is(':checked'); // Get Checkbox state
        if (this.checked) //If true then checked all checkboxes
           $(".classofyourallcheckbox").prop('checked', true);
        else
           $(".classofyourallcheckbox").prop('checked', false); //or uncheck all textboxes 
    }); 
});
</script>

I believe that as of PHP 5.3, you can use const outside of classes, as shown here in the second example:

http://www.php.net/manual/en/language.constants.syntax.php

<?php
// Works as of PHP 5.3.0
const CONSTANT = 'Hello World';

echo CONSTANT;
?>

To decompile APK Use APKTool.
You can learn how APKTool works on http://www.decompileandroid.com/ or by reading the documentation.

1. When you want to store 'wide' (Unicode) characters.
2. Yes: 255 of them (excluding 0).
3. Yes.
4. Here's an introductory article: http://www.joelonsoftware.com/articles/Unicode.html

Install the colorlog package, you can use colors in your log messages immediately:

• Obtain a logger instance, exactly as you would normally do.
• Set the logging level. You can also use the constants like DEBUG and INFO from the logging module directly.
• Set the message formatter to be the ColoredFormatter provided by the colorlog library.

import colorlog

logger = colorlog.getLogger()
logger.setLevel(colorlog.colorlog.logging.DEBUG)

handler = colorlog.StreamHandler()
handler.setFormatter(colorlog.ColoredFormatter())
logger.addHandler(handler)

logger.debug("Debug message")
logger.info("Information message")
logger.warning("Warning message")
logger.error("Error message")
logger.critical("Critical message")

output:

UPDATE: extra info

Just update ColoredFormatter:

handler.setFormatter(colorlog.ColoredFormatter('%(log_color)s [%(asctime)s] %(levelname)s [%(filename)s.%(funcName)s:%(lineno)d] %(message)s', datefmt='%a, %d %b %Y %H:%M:%S'))

output:

Package:

pip install colorlog

output:

A handy base R option could be colMeans():

df[, colMeans(is.na(df)) != 1]

In here, We can define user defined comparator:

Below code :

 import java.util.*;
 import java.util.Collections;
 import java.util.Comparator; 


 class Checker implements Comparator<String>
 {
    public int compare(String str1, String str2)
    {
        if (str1.length() < str2.length()) return -1;
        else                               return 1;
    }
 }


class Main
{  
   public static void main(String args[])
    {  
      PriorityQueue<String> queue=new PriorityQueue<String>(5, new Checker());  
      queue.add("india");  
      queue.add("bangladesh");  
      queue.add("pakistan");  
 
      while (queue.size() != 0)
      {
         System.out.printf("%s\n",queue.remove());
      }
   }  
}  

Output :

   india                                               
   pakistan                                         
   bangladesh

Use this extension and download image faster.

extension UIImageView {
    public func imageFromURL(urlString: String) {

        let activityIndicator = UIActivityIndicatorView(activityIndicatorStyle: .gray)
        activityIndicator.frame = CGRect.init(x: 0, y: 0, width: self.frame.size.width, height: self.frame.size.height)
        activityIndicator.startAnimating()
        if self.image == nil{
            self.addSubview(activityIndicator)
        }

        URLSession.shared.dataTask(with: NSURL(string: urlString)! as URL, completionHandler: { (data, response, error) -> Void in

            if error != nil {
                print(error ?? "No Error")

                let image = UIImage(data: data!)
                activityIndicator.removeFromSuperview()
                self.image = image
            })

        }).resume()
    }

Simplest:

Form form = new Form();
form.add("id", "1");    
form.add("name", "supercobra");
ClientResponse response = webResource
  .type(MediaType.APPLICATION_FORM_URLENCODED_TYPE)
  .post(ClientResponse.class, form);

You need to give relative or absolute or fixed positioning to your container (#shop) and set its zIndex to say 100.

You also need to give say relative positioning to your elements with the class content and lower zIndex say 97.

Do the above-mentioned with your images too and set their zIndex to 91.

And then position your button higher by setting its position to absolute and zIndex to 95

A UDF will only return a value it won't allow you to change the properties of a cell/sheet/workbook. Move your code to a Worksheet_Change event or similar to change properties.

Eg

Private Sub worksheet_change(ByVal target As Range)
  target.Font.Bold = True
End Sub

from urllib.request import Request, urlopen
from urllib.error import URLError, HTTPError
req = Request("http://stackoverflow.com")
try:
    response = urlopen(req)
except HTTPError as e:
    print('The server couldn\'t fulfill the request.')
    print('Error code: ', e.code)
except URLError as e:
    print('We failed to reach a server.')
    print('Reason: ', e.reason)
else:
    print ('Website is working fine')

Works on Python 3

You should be using the dirpath which you call root. The dirnames are supplied so you can prune it if there are folders that you don't wish os.walk to recurse into.

import os
result = [os.path.join(dp, f) for dp, dn, filenames in os.walk(PATH) for f in filenames if os.path.splitext(f)[1] == '.txt']

Edit:

After the latest downvote, it occurred to me that glob is a better tool for selecting by extension.

import os
from glob import glob
result = [y for x in os.walk(PATH) for y in glob(os.path.join(x[0], '*.txt'))]

Also a generator version

from itertools import chain
result = (chain.from_iterable(glob(os.path.join(x[0], '*.txt')) for x in os.walk('.')))

Edit2 for Python 3.4+

from pathlib import Path
result = list(Path(".").rglob("*.[tT][xX][tT]"))

Which version of Firefox on which platform is your client using?

The are people having the same problem as documented here in the Support Forum for Firefox. I hope you can find a solution there. Good luck!

Update:

Let your client check the settings in Firefox: On "Advanced" - "Encryption" there is a button "View Certificates". Look for "Comodo CA Limited" in the list. I saw that Comodo is the issuer of the certificate of that domain name/server. On two of my machines (FF 3.0.3 on Vista and Mac) the entry is in the list (by default/Mozilla).

You've probably miss-typed something above that bit of code or created your own class called IPAddress. If you're using the .net one, that function should be available.

Have you tried using System.Net.IPAddress just in case?

System.Net.IPAddress ipaddress = System.Net.IPAddress.Parse("127.0.0.1");  //127.0.0.1 as an example

The docs on Microsoft's site have a complete example which works fine on my machine.

What you need to do is this:

Settings | About Phone

Scroll to the bottom to build number. Tap on build number about 7 times. Each time you will get a popup message saying you are x steps away from being a developer

When you get to the final step you will get a message saying now you are a developer

Go back into settings and you will see a new setting Developer options there you will see a lot of options for developers. Enable USB debugging

Re-connect you phone to the usb, and you should see you device under adb devices.

I hope this answer helps someone else.

There is probably no need to use the ldpi , mdpi or hdpi qualifiers in this case.

When you define a dimension in a resource file you include the measurement unit. If you use sp units they are scaled according to the screen density so text at 15sp should appear roughly the same size on screens of differing density.
(The real screen density of the device isn't going to exactly match as Android generalises screen density into 120, 160, 240, 320, 480 and 640 dpi groups.)

When calling getResources().getDimension(R.dimen.textsize) it will return the size in pixels. If using sp it will scaled by the screen density,

Calling setText(float) sets the size in sp units. This is where the issue is,
i.e you have pixels measurements on one hand and sp unit on the other to fix do this:

textView.setTextSize(TypedValue.COMPLEX_UNIT_PX,
    getResources().getDimension(R.dimen.textsize));

Note you can also use

getResources().getDimensionPixelSize(R.dimen.textSize);

instead of getDimension() and it will round and convert to an non fractional value.

To install a new package and only that, you have two options:

1. Using the require command, just run:

   composer require new/package
   

   Composer will guess the best version constraint to use, install the package, and add it to composer.lock.

   You can also specify an explicit version constraint by running:

   composer require new/package ~2.5
   

–OR–

2. Using the update command, add the new package manually to composer.json, then run:

   composer update new/package
   

If Composer complains, stating "Your requirements could not be resolved to an installable set of packages.", you can resolve this by passing the flag --with-dependencies. This will whitelist all dependencies of the package you are trying to install/update (but none of your other dependencies).

Regarding the question asker's issues with Laravel and mcrypt: check that it's properly enabled in your CLI php.ini. If php -m doesn't list mcrypt then it's missing.

Important: Don't forget to specify new/package when using composer update! Omitting that argument will cause all dependencies, as well as composer.lock, to be updated.

Use the random module: http://docs.python.org/library/random.html

import random
random.sample(set([1, 2, 3, 4, 5, 6]), 2)

This samples the two values without replacement (so the two values are different).

This is very compact:

w['female'][w['female'] == 'female']=1
w['female'][w['female'] == 'male']=0

Another good one:

w['female'] = w['female'].replace(regex='female', value=1)
w['female'] = w['female'].replace(regex='male', value=0)

To truncate:

// Math.trunc() is part of the ES6 spec
console.log(Math.trunc( 1.5 ));  // returns 1
console.log(Math.trunc( -1.5 )); // returns -1
// Math.floor( -1.5 ) would return -2, which is probably not what you wanted

To round:

console.log(Math.round( 1.5 ));  // 2
console.log(Math.round( 1.49 )); // 1
console.log(Math.round( -1.6 )); // -2
console.log(Math.round( -1.3 )); // -1

If you're stuck with pre-5.10, then the solutions provided above will not fully replicate the say function. For example

sub say { print @_, "\n"; }

Will not work with invocations such as

say for @arr;

or

for (@arr) {
    say;
}

... because the above function does not act on the implicit global $_ like print and the real say function.

To more closely replicate the perl 5.10+ say you want this function

sub say {
    if (@_) { print @_, "\n"; }
    else { print $_, "\n"; }
}

Which now acts like this

my @arr = qw( alpha beta gamma );
say @arr;
# OUTPUT
# alphabetagamma
#
say for @arr;
# OUTPUT
# alpha
# beta
# gamma
#

The say builtin in perl6 behaves a little differently. Invoking it with say @arr or @arr.say will not just concatenate the array items, but instead prints them separated with the list separator. To replicate this in perl5 you would do this

sub say {
    if (@_) { print join($", @_) . "\n"; }
    else { print $_ . "\n"; }
}

$" is the global list separator variable, or if you're using English.pm then is is $LIST_SEPARATOR

It will now act more like perl6, like so

say @arr;
# OUTPUT
# alpha beta gamma
#

AngularJS pass string, numbers and booleans by value while it passes arrays and objects by reference. So you can create an empty object and make your date a property of that object. In that way angular will detect model changes.

In controller

app.module('yourModule').controller('yourController',function($scope){
$scope.vm={selectedDate:''}
});

In html

<div ng-controller="yourController">
<input id="selectedDueDate" type="text" ng-model="vm.selectedDate" />
</div>

the warning or error of kind IMPLICIT DECLARATION is that the compiler is expecting a Function Declaration/Prototype..

It might either be a header file or your own function Declaration..

I guess you should add android:centerColor

<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient
  android:startColor="#FFFFFF"
  android:centerColor="#000000"
  android:endColor="#FFFFFF"
  android:angle="0" />
</shape>

This example displays a horizontal gradient from white to black to white.

Is there any equivalent for the truststore? How can I view the trusted certificates?

Yes there is.The exact same command since keystore and truststore differ only in what they store i.e. private key or signed public key (certificate)

No other difference

Update 2018...

card has replaced the well.

Bootstrap 4

<div class="card card-body bg-light">

</div>

or, as two DIVs...

<div class="card bg-light">
    <div class="card-body">

    </div>
</div>

(Note: in Bootstrap 4 Alpha, these were known as card-block instead of card-body and bg-faded instead of bg-light)

My neat JavaScript trick is to separate the entire scenario into two different functions!

To prepare things, one global variable is declared and one event handler is defined:

  var tTimeout;
  element.addEventListener("transitionend", afterTransition, true);//firefox
  element.addEventListener("webkitTransitionEnd", afterTransition, true);//chrome

Then, when hiding element, I use something like this:

function hide(){
  element.style.opacity = 0;
}

function afterTransition(){
  element.style.display = 'none';
}

For reappearing the element, I am doing something like this:

function show(){
  element.style.display = 'block';
  tTimeout = setTimeout(timeoutShow, 100);
}

function timeoutShow(){
  element.style.opacity = 1;
}

It works, so far!

The reason behind this error is : Flask app is already running, hasn't shut down and in middle of that we try to start another instance by: with app.app_context(): #Code Before we use this with statement we need to make sure that scope of the previous running app is closed.

Like this.

.divContainer input[type="text"] {
  width:150px;
}
.divContainer input[type="radio"] {
  width:20px;
}

You can use a watchpoint for this (A breakpoint on data instead of code).

You can start by using watch i.
Then set a condition for it using condition <breakpoint num> i == 5

You can get the breakpoint number by using info watch

Spatial Indices, in particular R-trees and KD-trees, store spatial data efficiently. They are good for geographical map coordinate data and VLSI place and route algorithms, and sometimes for nearest-neighbor search.

Bit Arrays store individual bits compactly and allow fast bit operations.

The function STR_TO_DATE(COLUMN, '%input_format') can do it, you only have to specify the input format. Example : to convert p052011

SELECT STR_TO_DATE('p052011','p%m%Y') FROM your_table;

The result : 2011-05-00

Here's a solution to the general case that doesn't involve needing to know the length of the array ahead of time, using collect, or using udfs. Unfortunately this only works for spark version 2.1 and above, because it requires the posexplode function.

Suppose you had the following DataFrame:

df = spark.createDataFrame(
    [
        [1, 'A, B, C, D'], 
        [2, 'E, F, G'], 
        [3, 'H, I'], 
        [4, 'J']
    ]
    , ["num", "letters"]
)
df.show()
#+---+----------+
#|num|   letters|
#+---+----------+
#|  1|A, B, C, D|
#|  2|   E, F, G|
#|  3|      H, I|
#|  4|         J|
#+---+----------+

Split the letters column and then use posexplode to explode the resultant array along with the position in the array. Next use pyspark.sql.functions.expr to grab the element at index pos in this array.

import pyspark.sql.functions as f

df.select(
        "num",
        f.split("letters", ", ").alias("letters"),
        f.posexplode(f.split("letters", ", ")).alias("pos", "val")
    )\
    .show()
#+---+------------+---+---+
#|num|     letters|pos|val|
#+---+------------+---+---+
#|  1|[A, B, C, D]|  0|  A|
#|  1|[A, B, C, D]|  1|  B|
#|  1|[A, B, C, D]|  2|  C|
#|  1|[A, B, C, D]|  3|  D|
#|  2|   [E, F, G]|  0|  E|
#|  2|   [E, F, G]|  1|  F|
#|  2|   [E, F, G]|  2|  G|
#|  3|      [H, I]|  0|  H|
#|  3|      [H, I]|  1|  I|
#|  4|         [J]|  0|  J|
#+---+------------+---+---+

Now we create two new columns from this result. First one is the name of our new column, which will be a concatenation of letter and the index in the array. The second column will be the value at the corresponding index in the array. We get the latter by exploiting the functionality of pyspark.sql.functions.expr which allows us use column values as parameters.

df.select(
        "num",
        f.split("letters", ", ").alias("letters"),
        f.posexplode(f.split("letters", ", ")).alias("pos", "val")
    )\
    .drop("val")\
    .select(
        "num",
        f.concat(f.lit("letter"),f.col("pos").cast("string")).alias("name"),
        f.expr("letters[pos]").alias("val")
    )\
    .show()
#+---+-------+---+
#|num|   name|val|
#+---+-------+---+
#|  1|letter0|  A|
#|  1|letter1|  B|
#|  1|letter2|  C|
#|  1|letter3|  D|
#|  2|letter0|  E|
#|  2|letter1|  F|
#|  2|letter2|  G|
#|  3|letter0|  H|
#|  3|letter1|  I|
#|  4|letter0|  J|
#+---+-------+---+

Now we can just groupBy the num and pivot the DataFrame. Putting that all together, we get:

df.select(
        "num",
        f.split("letters", ", ").alias("letters"),
        f.posexplode(f.split("letters", ", ")).alias("pos", "val")
    )\
    .drop("val")\
    .select(
        "num",
        f.concat(f.lit("letter"),f.col("pos").cast("string")).alias("name"),
        f.expr("letters[pos]").alias("val")
    )\
    .groupBy("num").pivot("name").agg(f.first("val"))\
    .show()
#+---+-------+-------+-------+-------+
#|num|letter0|letter1|letter2|letter3|
#+---+-------+-------+-------+-------+
#|  1|      A|      B|      C|      D|
#|  3|      H|      I|   null|   null|
#|  2|      E|      F|      G|   null|
#|  4|      J|   null|   null|   null|
#+---+-------+-------+-------+-------+

Those algorithms are both incorrect because of the comparison:

for( int i = 0; i < elements.length - 1; i++)

or

for(int i = 0; i + 1 < elements.length; i++) {

It's true that the array elements range from 0 to length - 1, but the comparison in that case should be less than or equal to. Those should be:

for(int i = 0; i < elements.length; i++) {

or

for(int i = 0; i <= elements.length - 1; i++) {

or

for(int i = 0; i + 1 <= elements.length; i++) {

The array ["a", "b"] would iterate as:

i = 0 is < 2: elements[0] yields "a"

i = 1 is < 2: elements[1] yields "b"

then exit the loop because 2 is not < 2.

The incorrect examples both exit the loop prematurely and only execute with the first element in this simple case of two elements.

External fragmentation
Total memory space is enough to satisfy a request or to reside a process in it, but it is not contiguous so it can not be used.

Internal fragmentation
Memory block assigned to process is bigger. Some portion of memory is left unused as it can not be used by another process.

These are what's known as Shadow Copy Folders.

Simplistically....and I really mean it:

When ASP.NET runs your app for the first time, it copies any assemblies found in the /bin folder, copies any source code files (found for example in the App_Code folder) and parses your aspx, ascx files to c# source files. ASP.NET then builds/compiles all this code into a runnable application.

One advantage of doing this is that it prevents the possibility of .NET assembly DLL's #(in the /bin folder) becoming locked by the ASP.NET worker process and thus not updatable.

ASP.NET watches for file changes in your website and will if necessary begin the whole process all over again.

Theoretically the folder shouldn't need any maintenance, but from time to time, and only very rarely you may need to delete contents. That said, I work for a hosting company, we run up to 1200 sites per shared server and I haven't had to touch this folder on any of the 250 or so machines for years.

This is outlined in the MSDN article Understanding ASP.NET Dynamic Compilation

The correct way for checking the visibility of an element with Protractor is to call the isDisplayed method. You should be careful though since isDisplayed does not return a boolean, but rather a promise providing the evaluated visibility. I've seen lots of code examples that use this method wrongly and therefore don't evaluate its actual visibility.

Example for getting the visibility of an element:

element(by.className('your-class-name')).isDisplayed().then(function (isVisible) {
    if (isVisible) {
        // element is visible
    } else {
        // element is not visible
    }
});

However, you don't need this if you are just checking the visibility of the element (as opposed to getting it) because protractor patches Jasmine expect() so it always waits for promises to be resolved. See github.com/angular/jasminewd

So you can just do:

expect(element(by.className('your-class-name')).isDisplayed()).toBeTruthy();

Since you're using AngularJS to control the visibility of that element, you could also check its class attribute for ng-hide like this:

var spinner = element.by.css('i.icon-spin');
expect(spinner.getAttribute('class')).not.toMatch('ng-hide'); // expect element to be visible

Further to @Penn's comment, and in case the link breaks, you can also achieve this by setting the Default property of the button to True (you can set this in the properties window, open by hitting F4)

That way whenever Return is hit, VBA knows to activate the button's click event. Similarly setting the Cancel property of a button to True would cause that button's click event to run whenever ESC key is hit (useful for gracefully exiting the Userform)

This is what you want

function isANumber(str){
  return !/\D/.test(str);
}

If you want to extend it just because you need Not-Swipeable behaviour, you dont need to do it. ViewPager2 provides nice property called : isUserInputEnabled

It would seem likely that the ActiveWorkbook has not been saved...

Try CurDir() instead.

You first need to check if directory exists file_exists('path_to_directory')

Then use mkdir(path_to_directory) to create a directory

mkdir( string $pathname [, int $mode = 0777 [, bool $recursive = FALSE [, resource $context ]]] ) : bool

More about mkdir() here

Full code here:

$structure = './depth1/depth2/depth3/';
if (!file_exists($structure)) {
    mkdir($structure);
}

<?php
// Example API call
$data = array(array (
    "REGION" => "MUMBAI",
    "LOCATION" => "NA",
    "STORE" => "AMAZON"));
// json encode data
$authToken = "xxxxxxxxxx";
$data_string = json_encode($data); 
// set up the curl resource
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://domainyouhaveapi.com");   
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'Content-Type:application/json',       
    'Content-Length: ' . strlen($data_string) ,
    'API-TOKEN-KEY:'.$authToken ));   // API-TOKEN-KEY is keyword so change according to ur key word. like authorization 
// execute the request
$output = curl_exec($ch);
//echo $output;
// Check for errors
if($output === FALSE){
    die(curl_error($ch));
}
echo($output) . PHP_EOL;
// close curl resource to free up system resources
curl_close($ch);

My answer is just a conceptual one without any source code. It might be useful for some readers like myself to understand.

It depends on your initial approach on how you architecture your app. There are basically two approaches.

1. You create one activity (base activity) and all the other views and screens will be fragments. That base activity contains the implementation for Drawer and Coordinator Layouts. It is actually my preferred way of doing because having small self-contained fragments will make app development easier and smoother.

2. If you have started your app development with activities, one for each screen , then you will probably create base activity, and all other activity extends from it. The base activity will contain the code for drawer and coordinator implementation. Any activity that needs drawer implementation can extend from base activity.

I would personally prefer avoiding to use fragments and activities mixed without any organizing. That makes the development more difficult and get you stuck eventually. If you have done it, refactor your code.

Solution is

1. Connect your computer to the internet

2. Click

Sync project with Gradle files

On toolbar

It will automatically sync the gradle.

$.get = $.ajax({type: 'GET'});

$.load() is a helper function which only can be invoked on elements.

$.ajax() gives you most control. you can specify if you want to POST data, got more callbacks etc.

You're not the only person having problems with Python 2.6 and MySQL (http://blog.contriving.net/2009/03/04/using-python-26-mysql-on-windows-is-nearly-impossible/). Here's an explanation how it should run under Python 2.5 http://i.justrealized.com/2008/04/08/how-to-install-python-and-django-in-windows-vista/ Good luck

        i = 1
    End If
Loop
Wscript.Echo "Notepad has been terminated."

It might be late but can help. On the first fragment or activity do declare a class...for example

   @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        description des = new description();

        if (requestCode == PICK_IMAGE_REQUEST && data != null && data.getData() != null) {
            filePath = data.getData();
            try {
                bitmap = MediaStore.Images.Media.getBitmap(getActivity().getContentResolver(), filePath);
                imageView.setImageBitmap(bitmap);
                ByteArrayOutputStream stream = new ByteArrayOutputStream();
                bitmap.compress(Bitmap.CompressFormat.PNG, 100, stream);
                constan.photoMap = bitmap;
            } catch (IOException e) {
                e.printStackTrace();
            }
       }
    }

public static class constan {
    public static Bitmap photoMap = null;
    public static String namePass = null;
}

Then on the second class/fragment do this..

Bitmap bm = postFragment.constan.photoMap;
final String itemName = postFragment.constan.namePass;

Hope it helps.

Yes, you can do print all keys using below bash script,

for key in $(redis-cli -p 6379 keys \*);
  do echo "Key : '$key'" 
     redis-cli -p 6379 GET $key;
done

where, 6379 is a port on which redis is running.

Step by step explanation how to make it work :

1- First create a python file according to the basic skeleton mentioned above. And save it to a path for example : "c:\PythonFiles\AppServerSvc.py"

import win32serviceutil
import win32service
import win32event
import servicemanager
import socket


class AppServerSvc (win32serviceutil.ServiceFramework):
    _svc_name_ = "TestService"
    _svc_display_name_ = "Test Service"


    def __init__(self,args):
        win32serviceutil.ServiceFramework.__init__(self,args)
        self.hWaitStop = win32event.CreateEvent(None,0,0,None)
        socket.setdefaulttimeout(60)

    def SvcStop(self):
        self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING)
        win32event.SetEvent(self.hWaitStop)

    def SvcDoRun(self):
        servicemanager.LogMsg(servicemanager.EVENTLOG_INFORMATION_TYPE,
                          servicemanager.PYS_SERVICE_STARTED,
                          (self._svc_name_,''))
        self.main()

    def main(self):
        # Your business logic or call to any class should be here
        # this time it creates a text.txt and writes Test Service in a daily manner 
        f = open('C:\\test.txt', 'a')
        rc = None
        while rc != win32event.WAIT_OBJECT_0:
            f.write('Test Service  \n')
            f.flush()
            # block for 24*60*60 seconds and wait for a stop event
            # it is used for a one-day loop
            rc = win32event.WaitForSingleObject(self.hWaitStop, 24 * 60 * 60 * 1000)
        f.write('shut down \n')
        f.close()

if __name__ == '__main__':
    win32serviceutil.HandleCommandLine(AppServerSvc)

2 - On this step we should register our service.

Run command prompt as administrator and type as:

sc create TestService binpath= "C:\Python36\Python.exe c:\PythonFiles\AppServerSvc.py" DisplayName= "TestService" start= auto

the first argument of binpath is the path of python.exe

second argument of binpath is the path of your python file that we created already

Don't miss that you should put one space after every "=" sign.

Then if everything is ok, you should see

[SC] CreateService SUCCESS

Now your python service is installed as windows service now. You can see it in Service Manager and registry under :

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TestService

3- Ok now. You can start your service on service manager.

You can execute every python file that provides this service skeleton.

During initial testing for Membership.ValidateUser with a SqlMembershipProvider, I use a hash (SHA1) algorithm combined with a salt, and, if I changed the salt length to a length not divisible by four, I received this error.

I have not tried any of the fixes above, but if the salt is being altered, this may help someone pinpoint that as the source of this particular error.

You are wrong in the way you display the data I guess, because for me:

    String dateString = "03/26/2012 11:49:00 AM";
    SimpleDateFormat dateFormat = new SimpleDateFormat("MM/dd/yyyy hh:mm:ss aa");
    Date convertedDate = new Date();
    try {
        convertedDate = dateFormat.parse(dateString);
    } catch (ParseException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    System.out.println(convertedDate);

Prints:

Mon Mar 26 11:49:00 EEST 2012

you can import bs4 instead of BeautifulSoup. Since bs4 is a built-in module, no additional installation is required.

from bs4 import BeautifulSoup
import re

doc = ['<html><head><title>Page title</title></head>',
       '<body><p id="firstpara" align="center">This is paragraph <b>one</b>.',
       '<p id="secondpara" align="blah">This is paragraph <b>two</b>.',
       '</html>']
soup = BeautifulSoup(''.join(doc))

print soup.prettify()

If you want to request, using requests module. request is using urllib, requests modules. but I personally recommendation using requests module instead of urllib

module install for using:

$ pip install requests

Here's how to use the requests module:

import requests as rq
res = rq.get('http://www.example.com')

print(res.content)
print(res.status_code)

Try using the ISO string

var isodate = new Date().toISOString()

See also: method definition at MDN.

You can use the replace function

UPDATE your_table SET field = REPLACE(your_field, 'cat','dog')

The function definition is as follows (got from here):

replace(string text, from text, to text)

and returns the modified text. You can also check out this sql fiddle.

import com.google.common.base

if(!Strings.isNullOrEmpty(String str)) {
   // Do your stuff here 
}

There are several options, including using the method you demonstrate, With, and using a variable.

My preference is option 4 below: Dim a variable of type Worksheet and store the worksheet and call the methods on the variable or pass it to functions, however any of the options work.

Sub Test()
  Dim SheetName As String
  Dim SearchText As String
  Dim FoundRange As Range

  SheetName = "test"      
  SearchText = "abc"

  ' 0. If you know the sheet is the ActiveSheet, you can use if directly.
  Set FoundRange = ActiveSheet.UsedRange.Find(What:=SearchText)
  ' Since I usually have a lot of Subs/Functions, I don't use this method often.
  ' If I do, I store it in a variable to make it easy to change in the future or
  ' to pass to functions, e.g.: Set MySheet = ActiveSheet
  ' If your methods need to work with multiple worksheets at the same time, using
  ' ActiveSheet probably isn't a good idea and you should just specify the sheets.

  ' 1. Using Sheets or Worksheets (Least efficient if repeating or calling multiple times)
  Set FoundRange = Sheets(SheetName).UsedRange.Find(What:=SearchText)
  Set FoundRange = Worksheets(SheetName).UsedRange.Find(What:=SearchText)

  ' 2. Using Named Sheet, i.e. Sheet1 (if Worksheet is named "Sheet1"). The
  ' sheet names use the title/name of the worksheet, however the name must
  ' be a valid VBA identifier (no spaces or special characters. Use the Object
  ' Browser to find the sheet names if it isn't obvious. (More efficient than #1)
  Set FoundRange = Sheet1.UsedRange.Find(What:=SearchText)

  ' 3. Using "With" (more efficient than #1)
  With Sheets(SheetName)
    Set FoundRange = .UsedRange.Find(What:=SearchText)
  End With
  ' or possibly...
  With Sheets(SheetName).UsedRange
    Set FoundRange = .Find(What:=SearchText)
  End With

  ' 4. Using Worksheet variable (more efficient than 1)
  Dim MySheet As Worksheet
  Set MySheet = Worksheets(SheetName)
  Set FoundRange = MySheet.UsedRange.Find(What:=SearchText)

  ' Calling a Function/Sub
  Test2 Sheets(SheetName) ' Option 1
  Test2 Sheet1 ' Option 2
  Test2 MySheet ' Option 4

End Sub

Sub Test2(TestSheet As Worksheet)
    Dim RowIndex As Long
    For RowIndex = 1 To TestSheet.UsedRange.Rows.Count
        If TestSheet.Cells(RowIndex, 1).Value = "SomeValue" Then
            ' Do something
        End If
    Next RowIndex
End Sub

If you add Settings to a Class Library project in Visual Studio (Project Properties, Settings), it will add an app.config file to your project with the relevant userSettings/applicatioNSettings sections, and the default values for these settings from your Settings.settings file.

However this configuration file will not be used at runtime - instead the class library uses the configuration file of its hosting application.

I believe the main reason for generating this file is so that you can copy/paste the settings into the host application's configuration file.

right way is

import datetime
isinstance(x, datetime.date)

When I try this on my machine it works fine. You need to look into why datetime.date is not a class. Are you perhaps masking it with something else? or not referencing it correctly for your import?

W3C make it clear, on the specification about Button element

Button may be seen as a generic class for all kind of Buttons with no default behavior.

Restart the kernel. Then look at the colors you get, say, when you import. My spyder2 (python 2.7) uses Anaconda's ipython 5.3.0 and import is pink, the best matching scheme for the editor is Monokai, you choose this in

Tools > Preferences > Syntax coloring

My spyder3, when choosing dark IPython (2.4.1) background prints colors a bit different than Monokai, but if you go to

Tools > Preferences > Syntax coloring  

you go to Monokai tab and tweak the colors a bit. I had to change builtin from lilac to cyan

Javascript using the onLoad() event, will wait for the page to be loaded before executing.

<body onload="somecode();" >

If you're using the jQuery framework's document ready function the code will load as soon as the DOM is loaded and before the page contents are loaded:

$(document).ready(function() {
    // jQuery code goes here
});

Even though you've accepted an answer, I want to post this method. I use jQuery to center it vertically instead of css (although both of these methods work). Here is a fiddle, and I'll post the code here anyways.

HTML:

<h1>Hello world!</h1>

Javascript (jQuery):

$(document).ready(function(){
  $('h1').css({ 'width':'100%', 'text-align':'center' });
  var h1 = $('h1').height();
  var h = h1/2;
  var w1 = $(window).height();
  var w = w1/2;
  var m = w - h
  $('h1').css("margin-top",m + "px")
});

This takes the height of the viewport, divides it by two, subtracts half the height of the h1, and sets that number to the margin-top of the h1. The beauty of this method is that it works on multiple-line h1s.

EDIT: I modified it so that it centered it every time the window is resized.

You need to construct a date string. You're using / or - operators which do MATH/numeric operations on the numeric return values of DATEPART. Then DATENAME is taking that numeric value and interpreting it as a date.

You need to convert it to a string. For example:

SELECT (
  DATENAME(dw, 
  CAST(DATEPART(m, GETDATE()) AS VARCHAR) 
  + '/' 
  + CAST(DATEPART(d, myDateCol1) AS VARCHAR) 
  + '/' 
  + CAST(DATEPART(yy, getdate()) AS VARCHAR))
  )

The Python with statement is built-in language support of the Resource Acquisition Is Initialization idiom commonly used in C++. It is intended to allow safe acquisition and release of operating system resources.

The with statement creates resources within a scope/block. You write your code using the resources within the block. When the block exits the resources are cleanly released regardless of the outcome of the code in the block (that is whether the block exits normally or because of an exception).

Many resources in the Python library that obey the protocol required by the with statement and so can used with it out-of-the-box. However anyone can make resources that can be used in a with statement by implementing the well documented protocol: PEP 0343

Use it whenever you acquire resources in your application that must be explicitly relinquished such as files, network connections, locks and the like.

You can attempt to push the cookie val to another domain using an image tag.

Your mileage may vary when trying to do this because some browsers require you to have a proper P3P Policy on the WebApp2 domain or the browser will reject the cookie.

If you look at plus.google.com p3p policy you will see that their policy is:

CP="This is not a P3P policy! See http://www.google.com/support/accounts/bin/answer.py?hl=en&answer=151657 for more info."

that is the policy they use for their +1 buttons to these cross domain requests.

Another warning is that if you are on https make sure that the image tag is pointing to an https address also otherwise the cookies will not set.

There's a lot of buggy code here and regex solutions are very slow. I found a solution that works up to 20x faster than the regex counterpart and is elegantly simple:

    /*
    *   @param      string      parameter to return the value of.
    *   @return     string      value of chosen parameter, if found.
    */
    function get_param(return_this)
    {
        return_this = return_this.replace(/\?/ig, "").replace(/=/ig, ""); // Globally replace illegal chars.

        var url = window.location.href;                                   // Get the URL.
        var parameters = url.substring(url.indexOf("?") + 1).split("&");  // Split by "param=value".
        var params = [];                                                  // Array to store individual values.

        for(var i = 0; i < parameters.length; i++)
            if(parameters[i].search(return_this + "=") != -1)
                return parameters[i].substring(parameters[i].indexOf("=") + 1).split("+");

        return "Parameter not found";
    }

console.log(get_param("parameterName"));

Regex is not the be-all and end-all solution, for this type of problem simple string manipulation can work a huge amount more efficiently. Code source.

In bootstrap 4, if you want to over-ride when navbar-expand-*, expands and collapses and shows and hides the hamburger (navbar-toggler) you have to find that style/definition in bootstrap.css, and redefine it in your own customstyle.css (or directly in bootstrap.css if you are so inclined).

Eg. I wanted the navbar-expand-lg to collapses and shows the navbar-toggler at 950px. In bootstrap.css I find:

@media (max-width: 991.98px) {
  .navbar-expand-lg > .container,
  .navbar-expand-lg > .container-fluid {
    padding-right: 0;
    padding-left: 0;
  }
}

And below that ...

@media (min-width:992px) { 
    ... lots of styling ...
}

I copied both @media queries and stuck them in my style.css, then modified the size to fit my needs. I my case I wanted it to collapse at 950px. The @media queries must need to be different sizes (I'm guessing), so I set container max-width to 949.98px and used the 950px for the other @media query and so the following code was appended to my style.css. This was not easy to detangle from twisted solutions I found on Stackoverflow and elsewhere. Hope this helps.

@media (max-width: 949.98px) {
    .navbar-expand-lg > .container,
    .navbar-expand-lg > .container-fluid {
        padding-right: 0;
        padding-left: 0;
    }
}

@media (min-width: 950px) {
    .navbar-expand-lg {
        -webkit-box-orient: horizontal;
        -webkit-box-direction: normal;
        -ms-flex-flow: row nowrap;

While using laravel 5 use this code as you don`t need headers.

return response()->download($pathToFile); .

If you are using Fileentry you can use below function for downloading.

// download file
public function download($fileId){  
    $entry = Fileentry::where('file_id', '=', $fileId)->firstOrFail();
    $pathToFile=storage_path()."/app/".$entry->filename;
    return response()->download($pathToFile);

I don't know about doing it in Yii, but you could just do this, and it should work anywhere (largely lifted from my answer here):

// Get HTTP/HTTPS (the possible values for this vary from server to server)
$myUrl = (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] && !in_array(strtolower($_SERVER['HTTPS']),array('off','no'))) ? 'https' : 'http';
// Get domain portion
$myUrl .= '://'.$_SERVER['HTTP_HOST'];
// Get path to script
$myUrl .= $_SERVER['REQUEST_URI'];
// Add path info, if any
if (!empty($_SERVER['PATH_INFO'])) $myUrl .= $_SERVER['PATH_INFO'];

$get = $_GET; // Create a copy of $_GET
unset($get['lg']); // Unset whatever you don't want
if (count($get)) { // Only add a query string if there's anything left
  $myUrl .= '?'.http_build_query($get);
}

echo $myUrl;

Alternatively, you could pass the result of one of the Yii methods into parse_url(), and manipulate the result to re-build what you want.

A common "Pythonic" way to handle this kind of situation is known as EAFP for "It's easier to ask forgiveness than permission". Which usually means writing code that assumes everything is fine, but then wrapping it with a try...except block to handle things—just in case—it's not.

Here's that coding style applied to your problem:

try:
    my_value = int(my_value)
except TypeError:
    my_value = 0  # or whatever you want to do

answer = my_value / divisor

Or perhaps the even simpler and slightly faster:

try:
    answer = int(my_value) / divisor
except TypeError:
    answer = 0

The inverse and more traditional approach is known as LBYL which stands for "Look before you leap" is what @Soviut and some of the others have suggested. For additional coverage of this topic see my answer and associated comments to the question Determine whether a key is present in a dictionary elsewhere on this site.

One potential problem with EAFP is that it can hide the fact that something is wrong with some other part of your code or third-party module you're using, especially when the exceptions frequently occur (and therefore aren't really "exceptional" cases at all).

if you have

ReferenceError: Base64 is not defined

you can upload your file here you will have something as :

data:image/jpeg;base64,/veryLongBase64Encode....

on your js do :

var imgData = 'data:image/jpeg;base64,/veryLongBase64Encode....'
var doc = new jsPDF()

doc.setFontSize(40)
doc.addImage(imgData, 'JPEG', 15, 40, 180, 160)

Can see example here

Simply like that:

arr.join("")

Running from the command line means running from the terminal or DOS shell. You are running it from Python itself.

You can use this method for validating email address in java.

public class EmailValidator {
    private Pattern pattern;
    private Matcher matcher;

    private static final String EMAIL_PATTERN = 
        "^[_A-Za-z0-9-\\+]+(\\.[_A-Za-z0-9-]+)*@"
        + "[A-Za-z0-9-]+(\\.[A-Za-z0-9]+)*(\\.[A-Za-z]{2,})$";

    public EmailValidator() {
        pattern = Pattern.compile(EMAIL_PATTERN);
    }

    /**
    * Validate hex with regular expression
    * 
    * @param hex
    *            hex for validation
    * @return true valid hex, false invalid hex
    */
    public boolean validate(final String hex) {

    matcher = pattern.matcher(hex);
    return matcher.matches();

    }
}

This was how added my headers in my flask application and it worked perfectly

@app.after_request
def add_header(response):
    response.headers['X-Content-Type-Options'] = 'nosniff'
    return response

There Are 2 ways to return a string from the controller to the view:

First

You could return only the string, but it will not be included in your .cshtml file. it will be just a string appearing in your browser.

Second

You could return a string as the Model object of View Result.

Here is the code sample to do this:

public class HomeController : Controller
{
    // GET: Home
    // this will return just a string, not html
    public string index()
    {
        return "URL to show";
    }

    public ViewResult AutoProperty()
    {   
        string s = "this is a string ";
        // name of view , object you will pass
        return View("Result", s);

    }
}

In the view file to run AutoProperty, It will redirect you to the Result view and will send s
code to the view

<!--this will make this file accept string as it's model-->
@model string

@{
    Layout = null;
}

<!DOCTYPE html>

<html>
<head>
    <meta name="viewport" content="width=device-width" />
    <title>Result</title>
</head>
<body>
    <!--this will represent the string -->
    @Model
</body>
</html>

I run this at http://localhost:60227/Home/AutoProperty.

If you're able to extract the loop code into a function, a return statement can be used to exit the outermost loop at any time.

def foo():
    for x in range(10):
        for y in range(10):
            print(x*y)
            if x*y > 50:
                return
foo()

If it's hard to extract that function you could use an inner function, as @bjd2385 suggests, e.g.

def your_outer_func():
    ...
    def inner_func():
        for x in range(10):
            for y in range(10):
                print(x*y)
                if x*y > 50:
                    return
    inner_func()
    ...

Go 1.11 will have a feature called go modules and you can simply add a dependency with a version. Follow these steps:

go mod init .
go mod edit -require github.com/wilk/[email protected]
go get -v -t ./...   
go build
go install 

Here's more info on that topic - https://github.com/golang/go/wiki/Modules

try this ^^

$(document).ready(function() {
        $("form").bind("keypress", function(e) {
            if (e.keyCode == 13) {
                return false;
            }
        });
    });

Hope this helps

Of course @Stephan202 has given a really nice answer. I am providing an alternative.

def compressx(min_index = 3, max_index = 6, x = ['a', 'b', 'c', 'd', 'e', 'f', 'g']):
    x = x[:min_index] + [''.join(x[min_index:max_index])] + x[max_index:]
    return x
compressx()

>>>['a', 'b', 'c', 'def', 'g']

You can also do the following.

x = x[:min_index] + [''.join(x[min_index:max_index])] + x[max_index:]
print(x)

>>>['a', 'b', 'c', 'def', 'g']

If you are looking for a library to get the job done, try:

1. Guava 26.0 documented here

   return XmlEscapers.xmlContentEscaper().escape(text);

   Note: There is also an xmlAttributeEscaper()

2. Apache Commons Text 1.4 documented here

   StringEscapeUtils.escapeXml11(text)

   Note: There is also an escapeXml10() method

To try and answer your main question:

why would you use .append() rather then .after() or vice verses?

When you are manipulating the DOM with jquery the methods you use depend on the result you want and a frequent use is to replace content.

In replacing content you want to .remove() the content and replace it with new content. If you .remove() the existing tag and then try to use .append() it won't work because the tag itself has been removed, whereas if you use .after(), the new content is added 'outside' the (now removed) tag and isn't affected by the previous .remove().

Do you mean just? alert()

function hello_world(){ alert("hello world"); }

i using laravel 5.* i figure i have a file call .env in the root of the project that look something like this:

APP_ENV=local
APP_DEBUG=true
APP_KEY=SomeRandomString

DB_HOST=localhost
DB_DATABASE=homestead
DB_USERNAME=homestead
DB_PASSWORD=secret

CACHE_DRIVER=file
SESSION_DRIVER=file
QUEUE_DRIVER=sync

MAIL_DRIVER=smtp
MAIL_HOST=mailtrap.io
MAIL_PORT=2525
MAIL_USERNAME=null
MAIL_PASSWORD=null
MAIL_ENCRYPTION=null

And that was over writing the bd configuration so you can wheather deleted those config vars so laravel take the configuration under /config or set up your configuration here.

I did the second and it works for me :)

I have came across the same issue, and noticed that my API has not hosted in the root folder and in an virtual directory. I moved my API to the root folder in IIS and worked.

A deleted function is implicitly inline

(Addendum to existing answers)

... And a deleted function shall be the first declaration of the function (except for deleting explicit specializations of function templates - deletion should be at the first declaration of the specialization), meaning you cannot declare a function and later delete it, say, at its definition local to a translation unit.

Citing [dcl.fct.def.delete]/4:

A deleted function is implicitly inline. ( Note: The one-definition rule ([basic.def.odr]) applies to deleted definitions. — end note ] A deleted definition of a function shall be the first declaration of the function or, for an explicit specialization of a function template, the first declaration of that specialization. [ Example:

struct sometype {
  sometype();
};
sometype::sometype() = delete;      // ill-formed; not first declaration

— end example )

A primary function template with a deleted definition can be specialized

Albeit a general rule of thumb is to avoid specializing function templates as specializations do not participate in the first step of overload resolution, there are arguable some contexts where it can be useful. E.g. when using a non-overloaded primary function template with no definition to match all types which one would not like implicitly converted to an otherwise matching-by-conversion overload; i.e., to implicitly remove a number of implicit-conversion matches by only implementing exact type matches in the explicit specialization of the non-defined, non-overloaded primary function template.

Before the deleted function concept of C++11, one could do this by simply omitting the definition of the primary function template, but this gave obscure undefined reference errors that arguably gave no semantic intent whatsoever from the author of primary function template (intentionally omitted?). If we instead explicitly delete the primary function template, the error messages in case no suitable explicit specialization is found becomes much nicer, and also shows that the omission/deletion of the primary function template's definition was intentional.

#include <iostream>
#include <string>

template< typename T >
void use_only_explicit_specializations(T t);

template<>
void use_only_explicit_specializations<int>(int t) {
    std::cout << "int: " << t;
}

int main()
{
    const int num = 42;
    const std::string str = "foo";
    use_only_explicit_specializations(num);  // int: 42
    //use_only_explicit_specializations(str); // undefined reference to `void use_only_explicit_specializations< ...
}

However, instead of simply omitting a definition for the primary function template above, yielding an obscure undefined reference error when no explicit specialization matches, the primary template definition can be deleted:

#include <iostream>
#include <string>

template< typename T >
void use_only_explicit_specializations(T t) = delete;

template<>
void use_only_explicit_specializations<int>(int t) {
    std::cout << "int: " << t;
}

int main()
{
    const int num = 42;
    const std::string str = "foo";
    use_only_explicit_specializations(num);  // int: 42
    use_only_explicit_specializations(str);
    /* error: call to deleted function 'use_only_explicit_specializations' 
       note: candidate function [with T = std::__1::basic_string<char>] has 
       been explicitly deleted
       void use_only_explicit_specializations(T t) = delete; */
}

Yielding a more more readable error message, where the deletion intent is also clearly visible (where an undefined reference error could lead to the developer thinking this an unthoughtful mistake).

Returning to why would we ever want to use this technique? Again, explicit specializations could be useful to implicitly remove implicit conversions.

#include <cstdint>
#include <iostream>

void warning_at_best(int8_t num) { 
    std::cout << "I better use -Werror and -pedantic... " << +num << "\n";
}

template< typename T >
void only_for_signed(T t) = delete;

template<>
void only_for_signed<int8_t>(int8_t t) {
    std::cout << "UB safe! 1 byte, " << +t << "\n";
}

template<>
void only_for_signed<int16_t>(int16_t t) {
    std::cout << "UB safe! 2 bytes, " << +t << "\n";
}

int main()
{
    const int8_t a = 42;
    const uint8_t b = 255U;
    const int16_t c = 255;
    const float d = 200.F;

    warning_at_best(a); // 42
    warning_at_best(b); // implementation-defined behaviour, no diagnostic required
    warning_at_best(c); // narrowing, -Wconstant-conversion warning
    warning_at_best(d); // undefined behaviour!

    only_for_signed(a);
    only_for_signed(c);

    //only_for_signed(b);  
    /* error: call to deleted function 'only_for_signed' 
       note: candidate function [with T = unsigned char] 
             has been explicitly deleted
       void only_for_signed(T t) = delete; */

    //only_for_signed(d);
    /* error: call to deleted function 'only_for_signed' 
       note: candidate function [with T = float] 
             has been explicitly deleted
       void only_for_signed(T t) = delete; */
}

For a default export we do not use { } when we import.

For example,

File player.js

export default vx;

File index.js

import vx from './player';

File index.js

File player.js

If we want to import everything that we export then we use *:

By this way, you hold a form by his ID and throw all his content. This technic is fastiest.

document.forms["id_form"].reset();

Assign your image to a string. Eg image Now set icon to a fixed size label.

image.setIcon(new javax.swing.ImageIcon(image.getScaledInstance(50,50,WIDTH)));

array = array.uniq

uniq removes all duplicate elements and retains all unique elements in the array.

Google's Guava library also has these:

It looks like equals2 is just calling equals, so it will give the same results.

For gmail these settings worked for me, the ServicePointManager.SecurityProtocol line was necessary. Because I has setup 2 step verification I needed get a App Password from google app password generator.

SmtpClient mailer = new SmtpClient();
mailer.Host = "smtp.gmail.com";
mailer.Port = 587;
mailer.EnableSsl = true;
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls;

I think that a good idea is to use mb_stpos:

$haystack = 'How are you?';
$needle = 'are';

if (mb_strpos($haystack, $needle) !== false) {

    echo 'true';
}

Because this solution is case sensitive and safe for all Unicode characters.

But you can also do it like this (sauch response was not yet):

if (count(explode($needle, $haystack)) > 1) {

    echo 'true';
}

This solution is also case sensitive and safe for Unicode characters.

In addition you do not use the negation in the expression, which increases the readability of the code.

Here is other solution using function:

function isContainsStr($haystack, $needle) {

    return count(explode($needle, $haystack)) > 1;
}

if (isContainsStr($haystack, $needle)) {

    echo 'true';
}

Sort of already answered this in the comments, but just so this question has an answer, the problem was resolved through running:

sudo apt-get install python3-pymysql

I say a website can be a web application, but more often a website has multiple web applications. the relationship between the two is one of composition: website composed of applications.

a dating site might have a photo upload web application, a calendar one so you can mark when you're dating who.

These applications are embedded throughout the website.

Months are zero-based in Calendar. So 12 is interpreted as december + 1 month. Use

c.set(year, month - 1, day, 0, 0);  

Windows Form Iteration Technique

foreach (DataGridViewRow row in dataGridView1.Rows)
{
    if (row.Selected)
    {
        foreach (DataGridViewCell cell in row.Cells)
        {
            int index = cell.ColumnIndex;
            if (index == 0)
            {
                value = cell.Value.ToString();
                //do what you want with the value
            }
        }
    }
}

Had a similar problem, where I had to set the form back to pristine, but also to untouched, since $invalid and $error were both used to show error messages. Only using setPristine() was not enough to clear the error messages.

I solved it by using setPristine() and setUntouched(). (See Angular's documentation: https://docs.angularjs.org/api/ng/type/ngModel.NgModelController)

So, in my controller, I used:

$scope.form.setPristine(); 
$scope.form.setUntouched();

These two functions reset the complete form to $pristine and back to $untouched, so that all error messages were cleared.

This is improvement of Prateek answer - event is pass by parameter so reply_click not need to use global variable (and as far no body presents this variant)

function reply_click(e) {
  console.log(e.target.id);
}

<button id="1" onClick="reply_click(event)">B1</button>
<button id="2" onClick="reply_click(event)">B2</button>
<button id="3" onClick="reply_click(event)">B3</button>

There is no reliable way to check this. It's really under client's hand to tell you where it came from. You could imagine to use cookie or sessions informations put only on some pages of your website, but doing so your would break user experience with bookmarks.

Inline functions have special rules about what extern means. (Note that inline functions are a C99 or GNU extension; they weren't in original C.

For non-inline functions, extern is not needed as it is on by default.

Note that the rules for C++ are different. For example, extern "C" is needed on the C++ declaration of C functions that you are going to call from C++, and there are different rules about inline.

The problem may be if you are using older version of jQuery. Because older versions of jQuery have 'live' method instead of 'on'

Please run the below comments to update to Angular 6 from Angular 5

1. ng update @angular/cli
2. ng update @angular/core
3. npm install rxjs-compat (In order to support older version rxjs 5.6 )
4. npm install -g rxjs-tslint (To change from rxjs 5 to rxjs 6 format in code. Install globally then only will work)
5. rxjs-5-to-6-migrate -p src/tsconfig.app.json (After installing we have to change it in our source code to rxjs6 format)
6. npm uninstall rxjs-compat (Remove this finally)

Here is code you can get url segment.

{{ Request::segment(1) }}

If you don't want the data to be escaped then use {!! !!} else use {{ }}.

{!! Request::segment(1) !!}

I actually came across something like this not too long ago... check it out over on msdn (see the first answer)

in summary:

.cer - certificate stored in the X.509 standard format. This certificate contains information about the certificate's owner... along with public and private keys.

.pvk - files are used to store private keys for code signing. You can also create a certificate based on .pvk private key file.

.pfx - stands for personal exchange format. It is used to exchange public and private objects in a single file. A pfx file can be created from .cer file. Can also be used to create a Software Publisher Certificate.

I summarized the info from the page based on the suggestion from the comments.

I would suggest the use of exists instead of in because in some scenarios that implies null values the behavior is different, so

CREATE TRIGGER sampleTrigger
    ON database1.dbo.table1
    FOR DELETE
AS
    DELETE FROM database2.dbo.table2 childTable
    WHERE bar = 4 AND exists (SELECT id FROM deleted where deleted.id = childTable.id)
GO

You can create an array with all elements from a given Swift Set simply with

let array = Array(someSet)

This works because Set conforms to the SequenceType protocol and an Array can be initialized with a sequence. Example:

let mySet = Set(["a", "b", "a"])  // Set<String>
let myArray = Array(mySet)        // Array<String>
print(myArray) // [b, a]

If you only use this structure for once, i.e. create a global/static variable, you can remove typedef, and initialized this variable instantly:

struct {
    int id;
    char *name;
} employee = {
    .id = 0,
    .name = "none"
};

Then, you can use employee in your code after that.

In Ruby and other languages that support POSIX character classes in bracket expressions, you can do simply:

/\A[[:alpha:]]+\z/i

That will match alpha-chars in all Unicode alphabet languages. Easy peasy.

More info: http://en.wikipedia.org/wiki/Regular_expression#Character_classes http://ruby-doc.org/core-2.0/Regexp.html

SQL supports qualifying a column by prefixing the reference with either the full table name:

SELECT tbl_names.id, tbl_section.id, name, section
  FROM tbl_names
  JOIN tbl_section ON tbl_section.id = tbl_names.id 

...or a table alias:

SELECT n.id, s.id, n.name, s.section
  FROM tbl_names n
  JOIN tbl_section s ON s.id = n.id 

The table alias is the recommended approach -- why type more than you have to?

Why Do These Queries Look Different?

Secondly, my answers use ANSI-92 JOIN syntax (yours is ANSI-89). While they perform the same, ANSI-89 syntax does not support OUTER joins (RIGHT, LEFT, FULL). ANSI-89 syntax should be considered deprecated, there are many on SO who will not vote for ANSI-89 syntax to reinforce that. For more information, see this question.

<input type="text" inputmode="numeric">

With Inputmode you can give a hint to the browser.

Just to add that even though there are few usecases where you should use them, spawnSync / execFileSync / execSync were added to node.js in these commits: https://github.com/joyent/node/compare/d58c206862dc...e8df2676748e

Algorithm           ArrayList   LinkedList

ArrayLists are good for write-once-read-many or appenders, but bad at add/remove from the front or middle.

it depends, by that I mean it depends on what shell you are using. here are the constraints I see:

1. must run in the same process as your shell, to catch aliases and functions and variables that would effect the commands you can find, think PATH or EDITOR although EDITOR might be out of scope. You can have unexported variables that can effect things.
2. it is shell specific or your going off into the kernel, /proc/pid/enviorn and friends do not have enough information

I use ZSH so here is a zsh answer, it does the following 3 things:

1. dumps path
2. dumps alias names
3. dumps functions that are in the env
4. sorts them

here it is:

feed_me() {
    (alias | cut -f1 -d= ; hash -f; hash -v | cut -f 1 -d= ; typeset +f) | sort
}

If you use zsh this should do it.

GitLens has a nice Git history browser. Install GitLens from the extensions marketplace, and then run "Show GitLens Explorer" from the command palette.

If there is someone interested in achieve the @Pedro Silva solution in JS, I just ported this same solution for it:

const getBase64Size = (base64) => {
  let padding = base64.length
    ? getBase64Padding(base64)
    : 0
  return ((Math.ceil(base64.length / 4) * 3 ) - padding) / 1000
}

const getBase64Padding = (base64) => {
  return endsWith(base64, '==')
    ? 2
    : 1
}

const endsWith = (str, end) => {
  let charsFromEnd = end.length
  let extractedEnd = str.slice(-charsFromEnd)
  return extractedEnd === end
}

You can use finds null separated output option with read to iterate over directory structures safely.

#!/bin/bash
find . -type f -print0 | while IFS= read -r -d $'\0' file; 
  do echo "$file" ;
done

So for your case

#!/bin/bash
find . -maxdepth 1 -type f  -print0 | while IFS= read -r -d $'\0' file; do
  for ((i=0; i<=3; i++)); do
    ./MyProgram.exe "$file" 'Logs/'"`basename "$file"`""$i"'.txt'
  done
done

additionally

#!/bin/bash
while IFS= read -r -d $'\0' file; do
  for ((i=0; i<=3; i++)); do
    ./MyProgram.exe "$file" 'Logs/'"`basename "$file"`""$i"'.txt'
  done
done < <(find . -maxdepth 1 -type f  -print0)

will run the while loop in the current scope of the script ( process ) and allow the output of find to be used in setting variables if needed

Even though it is little late, but PHP has one better solution for this:

$words=str_word_count($myvalue, 1);
echo $words[0];

Define width of .absorbing-column

Set table-layout to auto and define an extreme width on .absorbing-column.

Here I have set the width to 100% because it ensures that this column will take the maximum amount of space allowed, while the columns with no defined width will reduce to fit their content and no further.

This is one of the quirky benefits of how tables behave. The table-layout: auto algorithm is mathematically forgiving.

You may even choose to define a min-width on all td elements to prevent them from becoming too narrow and the table will behave nicely.

table {_x000D_
    table-layout: auto;_x000D_
    border-collapse: collapse;_x000D_
    width: 100%;_x000D_
}_x000D_
table td {_x000D_
    border: 1px solid #ccc;_x000D_
}_x000D_
table .absorbing-column {_x000D_
    width: 100%;_x000D_
}

<table>_x000D_

    <tr>_x000D_
      <th>Column A</th>_x000D_

      <td>Data A.1 lorem</td>_x000D_

From the "Updating Chosen Dynamically" section in the docs: You need to trigger the 'chosen:updated' event on the field

$(document).ready(function() {

    $('select').chosen();

    $('button').click(function() {
        $('select').val(2);
        $('select').trigger("chosen:updated");
    });

});

NOTE: versions prior to 1.0 used the following:

$('select').trigger("liszt:updated");

If possible, add this to the main Apache configuration file. It is a lighter-weight solution, less processing required.

<VirtualHost 64.65.66.67>
        ServerName example.com
        Redirect permanent / http://www.example.com/
</VirtualHost>
<VirtualHost 64.65.66.67>
   ServerAdmin [email protected]
   ServerName www.example.com
   DocumentRoot /var/www/example
   .
   .
   . etc

So, the separate VirtualHost for "example.com" captures those requests and then permanently redirects them to your main VirtualHost. So there's no REGEX parsing with every request, and your client browsers will cache the redirect so they'll never (or rarely) request the "wrong" url again, saving you on server load.

Note, the trailing slash in Redirect permanent / http://www.example.com/. Without it, a redirect from example.com/asdf would redirect to http://www.example.comasdf instead of http://www.example.com/asdf.

Use Array(N+1).join("string_to_repeat")

Abrahamchez's solution https://developer.apple.com/library/ios/qa/qa1797/_index.html worked for me as follows. I had a single UITableviewcontroller as my initial view. I had tried the offset code and embedding in a navcon but neither solved the statusbar transparency.

Add a Viewcontroller and make it the initial view. This should show you critical Top & Bottom Layout Guides.

Drag the old Tableview into the View in the new controller.

Do all the stuff to retrofit the table into the new controller:

Change your old view controller.h file to inherit/subclass from UIViewController instead of UITableViewController.

Add UITableViewDataSource and UITableViewDelegate to the viewcontroller's .h.

Re-connect anything needed in the storyboard, such as a Searchbar.

The big thing is to get the constraints set up, as in the Apple Q&A. I didn't bother inserting a toolbar. Not certain the exact sequence. But a red icon appeared on the Layout Guides, perhaps when I built. I clicked it and let Xcode install/clean up the constraints.

Then I clicked everywhere until I found the Vertical Space constraint and changed its top value from -20 to 0 and it worked perfectly.

var markerArray = [];
markerArray.push(L.marker([51.505, -0.09]));
...
var group = L.featureGroup(markerArray).addTo(map);
map.fitBounds(group.getBounds());

Here's some status code, which you should know for your kind of knowledge.

Number 2 is correct. Use the correct design until and unless you detect a performance problem. Most RDBMS will not have a problem with a narrow but very long table.

Functions are not meant to be used that way, if you wish to perform data change you can just create a Stored Proc for that.

SBJSON *parser = [[SBJSON alloc] init];

NSString *url_str=[NSString stringWithFormat:@"Example APi Here"];

url_str = [url_str stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

NSURLRequest *request =[NSURLRequest requestWithURL:[NSURL URLWithString:url_str]];

NSData *response = [NSURLConnection sendSynchronousRequest:request  returningResponse:nil error:nil];

NSString *json_string = [[NSString alloc] initWithData:response1 encoding:NSUTF8StringEncoding]

NSDictionary *statuses = [parser2 objectWithString:json_string error:nil];

 NSArray *news_array=[[statuses3 objectForKey:@"sold_list"] valueForKey:@"list"];

    for(NSDictionary *news in news_array)
{

    @try {
        [title_arr addObject:[news valueForKey:@"gtitle"]];    //values Add to title array

    }
    @catch (NSException *exception) {

To add interceptor to a spring boot application, do the following

1. Create an interceptor class

   public class MyCustomInterceptor implements HandlerInterceptor{
   
       //unimplemented methods comes here. Define the following method so that it     
       //will handle the request before it is passed to the controller.
   
       @Override
       public boolean preHandle(HttpServletRequest request,HttpServletResponse  response){
       //your custom logic here.
           return true;
       }
   }
   

2. Define a configuration class

   @Configuration
   public class MyConfig extends WebMvcConfigurerAdapter{
       @Override
       public void addInterceptors(InterceptorRegistry registry){
           registry.addInterceptor(new MyCustomInterceptor()).addPathPatterns("/**");
       }
   }
   

3. Thats it. Now all your requests will pass through the logic defined under preHandle() method of MyCustomInterceptor.

Its simple, just make sure the data type in your columns are the same. For e.g. I faced the same error, that and an another error:

Error in contrasts<-(*tmp*, value = contr.funs[1 + isOF[nn]]) : contrasts can be applied only to factors with 2 or more levels

So, I went back to my excel file or csv file, set a filter on the variable throwing me an error and checked if the distinct datatypes are the same. And... Oh! it had numbers and strings, so I converted numbers to string and it worked just fine for me.

Best way is to handle this in an Ant script. You can create 2 different tasks for the 2 jar files. Specify class A as the main class in the manifst file for the first jar. similarly specify class B as the main class in the manifest file for the second jar.

you can easily run the Ant tasks from Netbeans.

I would try to avoid changing the xticklabels if possible, otherwise it can get very confusing if you for example overplot your histogram with additional data.

Defining the range of your grid is probably the best and with imshow it can be done by adding the extent keyword. This way the axes gets adjusted automatically. If you want to change the labels i would use set_xticks with perhaps some formatter. Altering the labels directly should be the last resort.

fig, ax = plt.subplots(figsize=(6,6))

ax.imshow(hist, cmap=plt.cm.Reds, interpolation='none', extent=[80,120,32,0])
ax.set_aspect(2) # you may also use am.imshow(..., aspect="auto") to restore the aspect ratio

I found information about .bashrc and .bash_profile here to sum it up:

.bash_profile is executed when you login. Stuff you put in there might be your PATH and other important environment variables.

.bashrc is used for non login shells. I'm not sure what that means. I know that RedHat executes it everytime you start another shell (su to this user or simply calling bash again) You might want to put aliases in there but again I am not sure what that means. I simply ignore it myself.

.profile is the equivalent of .bash_profile for the root. I think the name is changed to let other shells (csh, sh, tcsh) use it as well. (you don't need one as a user)

There is also .bash_logout wich executes at, yeah good guess...logout. You might want to stop deamons or even make a little housekeeping . You can also add "clear" there if you want to clear the screen when you log out.

Also there is a complete follow up on each of the configurations files here

These are probably even distro.-dependant, not all distros choose to have each configuraton with them and some have even more. But when they have the same name, they usualy include the same content.

Please see this, more current solution before using a custom parsing function like below, or a 3rd party library.

The a code below works and is still useful in situations where URLSearchParams is not available, but it was written in a time when there was no native solution available in JavaScript. In modern browsers or Node.js, prefer to use the built-in functionality.

function parseURLParams(url) {
    var queryStart = url.indexOf("?") + 1,
        queryEnd   = url.indexOf("#") + 1 || url.length + 1,
        query = url.slice(queryStart, queryEnd - 1),
        pairs = query.replace(/\+/g, " ").split("&"),
        parms = {}, i, n, v, nv;

    if (query === url || query === "") return;

    for (i = 0; i < pairs.length; i++) {
        nv = pairs[i].split("=", 2);
        n = decodeURIComponent(nv[0]);
        v = decodeURIComponent(nv[1]);

        if (!parms.hasOwnProperty(n)) parms[n] = [];
        parms[n].push(nv.length === 2 ? v : null);
    }
    return parms;
}

Use as follows:

var urlString = "http://www.example.com/bar?a=a+a&b%20b=b&c=1&c=2&d#hash";
    urlParams = parseURLParams(urlString);

which returns a an object like this:

{
  "a"  : ["a a"],     /* param values are always returned as arrays */
  "b b": ["b"],       /* param names can have special chars as well */
  "c"  : ["1", "2"]   /* an URL param can occur multiple times!     */
  "d"  : [null]       /* parameters without values are set to null  */ 
} 

So

parseURLParams("www.mints.com?name=something")

gives

{name: ["something"]}

EDIT: The original version of this answer used a regex-based approach to URL-parsing. It used a shorter function, but the approach was flawed and I replaced it with a proper parser.

This is an improvement of the ideas expressed in other answers in order to show how to gain access to the ngRepeat properties ($index, $first, $middle, $last, $even, $odd) when using declarative syntax and isolate scope (Google recommended best practice) with an element-directive. Note the primary difference: scope.$parent.$last.

angular.module('myApp', [])
.directive('myRepeatDirective', function() {
  return {
    restrict: 'E',
    scope: {
      someAttr: '='
    },
    link: function(scope, element, attrs) {
      angular.element(element).css('color','blue');
      if (scope.$parent.$last){
        window.alert("im the last!");
      }
    }
  };
});

I had the same problem. Don't remember where I found it on the web, but here is what I did:

Click "Start button"

in the search box, enter "Turn windows features on or off"

in the features window, Click: "Internet Information Services"

Click: "World Wide Web Services"

Click: "Application Development Features"

Check (enable) the features. I checked all but CGI.

IIS - this configuration section cannot be used at this path (configuration locking?)

This is an option:

dbContext.Entry(entity).State = EntityState.Detached;

You can pass PHP arrays to JavaScript using json_encode PHP function.

<?php
    $phpArray = array(
        0 => "Mon", 
        1 => "Tue", 
        2 => "Wed", 
        3 => "Thu",
        4 => "Fri", 
        5 => "Sat",
        6 => "Sun",
    )
?>

<script type="text/javascript">

    var jArray = <?php echo json_encode($phpArray); ?>;

    for(var i=0; i<jArray.length; i++){
        alert(jArray[i]);
    }

 </script>

I assume that each house is stored in its own table and has an 'id' field, e.g house id. So when you loop through the houses and display them, you could do something like this:

<a href="house.php?id=<?php echo $house_id;?>">
  <?php echo $house_name;?>
</a>

Then in house.php, you would get the house id using $_GET['id'], validate it using is_numeric() and then display its info.

This worked for me:

use <Database>
EXEC  sp_change_users_login @Action='update_one', @UserNamePattern='<userLogin>',@LoginName='<userLogin>';

The problem can be visualized with:

SELECT sid FROM sys.sysusers WHERE name = '<userLogin>'
SELECT sid FROM sys.syslogins WHERE name = '<userLogin>';

when you upload your files to the server be careful ,some tomes your images will not appear on the web page and a crashed icon will appear that means your file path is not properly arranged or coded when you have the the following file structure the code should be like this File structure: ->web(main folder) ->images(subfolder)->logo.png(image in the sub folder)the code for the above is below follow this standard

 <img src="../images/logo.jpg" alt="image1" width="50px" height="50px">

if you uploaded your files to the web server by neglecting the file structure with out creating the folder web if you directly upload the files then your images will be broken you can't see images,then change the code as following

 <img src="images/logo.jpg" alt="image1" width="50px" height="50px">

You need to use "\n" not '\n' in your gsub. The different quote marks behave differently.

Double quotes " allow character expansion and expression interpolation ie. they let you use escaped control chars like \n to represent their true value, in this case, newline, and allow the use of #{expression} so you can weave variables and, well, pretty much any ruby expression you like into the text.

While on the other hand, single quotes ' treat the string literally, so there's no expansion, replacement, interpolation or what have you.

In this particular case, it's better to use either the .delete or .tr String method to delete the newlines.

In short there's no way to recover the passphrase for a pair of SSH keys. Why? Because it was intended this way in the first place for security reasons. The answers the other people gave you are all correct ways to CHANGE the password of your keys, not to recover them. So if you've forgotten your passphrase, the best you can do is create a new pair of SSH keys. Here's how to generate SSH keys and add it to your GitHub account.

If you know what column the text/pattern you're looking for (e.g. "yyy") is in, you can just check that specific column to see if it matches, and print it.

For example, given a file with the following contents, (called asdf.txt)

xxx yyy zzz

to only print the second column if it matches the pattern "yyy", you could do something like this:

awk '$2 ~ /yyy/ {print $2}' asdf.txt

Note that this will also match basically any line where the second column has a "yyy" in it, like these:

xxx yyyz zzz
xxx zyyyz

Just replace @latest with the version number you want to downgrade to. I wanted to downgrade to version 3.10.10, so I used this command:

npm install -g [email protected]

If you're not sure which version you should use, look at the version history. For example, you can see that 3.10.10 is the latest version of npm 3.

Perhaps the following, then your calculator can use arbitrary number base (e.g. hex, binary, base 7! etc): (untested)

def convert(str):
    try:
        base = 10  # default
        if ':' in str:
            sstr = str.split(':')
            base, str = int(sstr[0]), sstr[1]
        val = int(str, base)
    except ValueError:
        val = None

    return val

val = convert(raw_input("Enter value:"))
# 10     : Decimal
# 16:a   : Hex, 10
# 2:1010 : Binary, 10

Okay, the .NET 2.0 answers:

If you don't need to clone the values, you can use the constructor overload to Dictionary which takes an existing IDictionary. (You can specify the comparer as the existing dictionary's comparer, too.)

If you do need to clone the values, you can use something like this:

public static Dictionary<TKey, TValue> CloneDictionaryCloningValues<TKey, TValue>
   (Dictionary<TKey, TValue> original) where TValue : ICloneable
{
    Dictionary<TKey, TValue> ret = new Dictionary<TKey, TValue>(original.Count,
                                                            original.Comparer);
    foreach (KeyValuePair<TKey, TValue> entry in original)
    {
        ret.Add(entry.Key, (TValue) entry.Value.Clone());
    }
    return ret;
}

That relies on TValue.Clone() being a suitably deep clone as well, of course.

If you have a module with a class you want to import, you can do it like this.

module = __import__(filename)
instance = module.MyClass()

If you do not know what the class is named, you can iterate through the classes available from a module.

import inspect
module = __import__(filename)
for c in module.__dict__.values():
    if inspect.isclass(c):
        # You may need do some additional checking to ensure 
        # it's the class you want
        instance = c()

In my case the issue seemed due to ajax delays but was related to internal iframes inside the main page. In seleminum it is possible to switch to internal frames with:

    driver.switchTo().frame("body");
    driver.switchTo().frame("bodytab");

I use java. After that I was able to locate the element

    driver.findElement(By.id("e_46")).click();

If you want to get only ID in array, can use array_map:

    $data = array_map(function($object){
        return $object->ID;
    }, $data);

With that, return an array with ID in every pos.

MySQL WorkBench is free software and is developed by Oracle, you can import an SQL File or specify a database and it will generate an SQL Diagram which you can move around to make it more visually appealing. It runs on GNU/Linux and Windows and it's free and has a professional look..

Yes it stops execution so this is generally preferable to HAVING COUNT(*) > 0 which often won't.

With EXISTS if you look at the execution plan you will see that the actual number of rows coming out of table1 will not be more than 1 irrespective of number of matching records.

In some circumstances SQL Server can convert the tree for the COUNT query to the same as the one for EXISTS during the simplification phase (with a semi join and no aggregate operator in sight) an example of that is discussed in the comments here.

For more complicated sub trees than shown in the question you may occasionally find the COUNT performs better than EXISTS however. Because the semi join needs only retrieve one row from the sub tree this can encourage a plan with nested loops for that part of the tree - which may not work out optimal in practice.

Use beginUpdates and endUpdates to insert a new cell when the button clicked.

As @vadian said in comment, begin/endUpdates has no effect for a single insert/delete/move operation

First of all, append data in your tableview array

Yourarray.append([labeltext])  

Then update your table and insert a new row

// Update Table Data
tblname.beginUpdates()
tblname.insertRowsAtIndexPaths([
NSIndexPath(forRow: Yourarray.count-1, inSection: 0)], withRowAnimation: .Automatic)
tblname.endUpdates()

This inserts cell and doesn't need to reload the whole table but if you get any problem with this, you can also use tableview.reloadData()

Swift 3.0

tableView.beginUpdates()
tableView.insertRows(at: [IndexPath(row: yourArray.count-1, section: 0)], with: .automatic)
tableView.endUpdates()

Objective-C

[self.tblname beginUpdates];
NSArray *arr = [NSArray arrayWithObject:[NSIndexPath indexPathForRow:Yourarray.count-1 inSection:0]];
[self.tblname insertRowsAtIndexPaths:arr withRowAnimation:UITableViewRowAnimationAutomatic];
[self.tblname endUpdates];

Option 3

Iterators are faster than using the get operation, since the get operation has to start from the beginning if it has to do some traversal. It probably wouldn't make a difference in an ArrayList, but other data structures could see a noticeable speed difference. This is also compatible with things that aren't lists, like sets.

String[] out = new String[n];
Iterator<String> iterator = in.iterator();
for (int i = 0; i < n && iterator.hasNext(); i++)
    out[i] = iterator.next();

I had a similar problem, the scenario was like this:

• My Activity is adding/replacing list fragments.
• Each list fragment has a reference to the activity, to notify the activity when a list item is clicked (observer pattern).
• Each list fragment calls setRetainInstance(true); in its onCreate method.

The onCreate method of the activity was like this:

mMainFragment = (SelectionFragment) getSupportFragmentManager()
                .findFragmentByTag(MAIN_FRAGMENT_TAG);
        if (mMainFragment == null) {
            mMainFragment = new SelectionFragment();

            mMainFragment.setListAdapter(new ArrayAdapter<String>(this,
                    R.layout.item_main_menu, getResources().getStringArray(
                            R.array.main_menu)));
mMainFragment.setOnSelectionChangedListener(this);
            FragmentTransaction transaction = getSupportFragmentManager()
                    .beginTransaction();
            transaction.add(R.id.content, mMainFragment, MAIN_FRAGMENT_TAG);
            transaction.commit();
        }

The exception was thrown because the when configuration changes (device rotated), the activity is created, the main fragment is retrieved from the history of the fragment manager and at the same time the fragment already has an OLD reference to the destroyed activity

changing the implementation to this solved the problem:

mMainFragment = (SelectionFragment) getSupportFragmentManager()
                .findFragmentByTag(MAIN_FRAGMENT_TAG);
        if (mMainFragment == null) {
            mMainFragment = new SelectionFragment();

            mMainFragment.setListAdapter(new ArrayAdapter<String>(this,
                    R.layout.item_main_menu, getResources().getStringArray(
                            R.array.main_menu)));
            FragmentTransaction transaction = getSupportFragmentManager()
                    .beginTransaction();
            transaction.add(R.id.content, mMainFragment, MAIN_FRAGMENT_TAG);
            transaction.commit();
        }
        mMainFragment.setOnSelectionChangedListener(this);

you need to set your listeners each time the activity is created to avoid the situation where the fragments have references to old destroyed instances of the activity.

Using tail -f output should work.

The way to do this in code is:

[button sizeToFit];

If you are subclassing and want to add extra rules you can override:

- (CGSize)sizeThatFits:(CGSize)size;

after you get the response just do call this function to append data to your body element

function createDiv(responsetext)
{
    var _body = document.getElementsByTagName('body')[0];
    var _div = document.createElement('div');
    _div.innerHTML = responsetext;
    _body.appendChild(_div);
}

@satya code modified as below

function httpGet(theUrl)
{
    if (window.XMLHttpRequest)
    {// code for IE7+, Firefox, Chrome, Opera, Safari
        xmlhttp=new XMLHttpRequest();
    }
    else
    {// code for IE6, IE5
        xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
    }
    xmlhttp.onreadystatechange=function()
    {
        if (xmlhttp.readyState==4 && xmlhttp.status==200)
        {
            createDiv(xmlhttp.responseText);
        }
    }
    xmlhttp.open("GET", theUrl, false);
    xmlhttp.send();    
}

Your "bad" output is UTF-8 displayed as CP1252.

On Windows, many editors assume the default ANSI encoding (CP1252 on US Windows) instead of UTF-8 if there is no byte order mark (BOM) character at the start of the file. While a BOM is meaningless to the UTF-8 encoding, its UTF-8-encoded presence serves as a signature for some programs. For example, Microsoft Office's Excel requires it even on non-Windows OSes. Try:

df.to_csv('file.csv',encoding='utf-8-sig')

That encoder will add the BOM.

You can use the Web API FontFace constructor (also Typescript) without need of CSS:

export async function loadFont(fontFamily: string, url: string): Promise<void> {
    const font = new FontFace(fontFamily, `local(${fontFamily}), url(${url})`);
    // wait for font to be loaded
    await font.load();
    // add font to document
    document.fonts.add(font);
    // enable font with CSS class
    document.body.classList.add("fonts-loaded");
}

import ComicSans from "./assets/fonts/ComicSans.ttf";

loadFont("Comic Sans ", ComicSans).catch((e) => {
    console.log(e);
});

Declare a file font.ts with your modules (TS only):

declare module "*.ttf";
declare module "*.woff";
declare module "*.woff2";

If TS cannot find FontFace type as its still officially WIP, add this declaration to your project. It will work in your browser, except for IE.

Use this:

mainWindow = new BrowserWindow({width: 640, height: 360})
mainWindow.setMenuBarVisibility(false)

Reference: https://github.com/electron/electron/issues/1415

I tried mainWindow.setMenu(null), but it didn't work.

First, clone the repository using git, e.g. with:

git clone git://github.com/facebook/facebook-ios-sdk.git

That downloads the complete history of the repository, so you can switch to any version. Next, change into the newly cloned repository:

cd facebook-ios-sdk

... and use git checkout <COMMIT> to change to the right commit:

git checkout 91f25642453

That will give you a warning, since you're no longer on a branch, and have switched directly to a particular version. (This is known as "detached HEAD" state.) Since it sounds as if you only want to use this SDK, rather than actively develop it, this isn't something you need to worry about, unless you're interested in finding out more about how git works.

public static int [] locations={1,2,3};

public static test dot=new test();
