so in template, for e. g.:

{{ lookup('dig', ansible_host) }}

Notes:

• Since not only DNS name could be used in inventory a check if it's not IP already better be added
• Obviously enough this receipt wouldn't work as intended for indirect host specifications (like using jump hosts, for e. g.)

But still it serves 99 % (figuratively speaking) of use cases.

I use m_ for member variables just to take advantage of Intellisense and related IDE-functionality. When I'm coding the implementation of a class I can type m_ and see the combobox with all m_ members grouped together.

But I could live without m_ 's without problem, of course. It's just my style of work.

Fragment PHP (in console Cloud9):

echo "\n";
echo "1: first_srt=1\nsecnd_srt=2\n";
echo "\n";
echo '2: first_srt=1\nsecnd_srt=2\n';
echo "\n";
echo "==============\n";

I have extended cletus proposed answer to working code example.

1. One ExecutorService (pes) accepts Producer tasks.
2. One ExecutorService (ces) accepts Consumer tasks.
3. Both Producer and Consumer shares BlockingQueue.
4. Multiple Producer tasks generates different numbers.
5. Any of Consumer tasks can consume number generated by Producer

Code:

import java.util.concurrent.*;

public class ProducerConsumerWithES {
    public static void main(String args[]){
         BlockingQueue<Integer> sharedQueue = new LinkedBlockingQueue<Integer>();

         ExecutorService pes = Executors.newFixedThreadPool(2);
         ExecutorService ces = Executors.newFixedThreadPool(2);

         pes.submit(new Producer(sharedQueue,1));
         pes.submit(new Producer(sharedQueue,2));
         ces.submit(new Consumer(sharedQueue,1));
         ces.submit(new Consumer(sharedQueue,2));

                System.out.println("Produced:" + number + ":by thread:"+ threadNo);
                sharedQueue.put(number);
            } catch (Exception err) {
                err.printStackTrace();
            }
        }
    }
}

class Consumer implements Runnable{
    private final BlockingQueue<Integer> sharedQueue;
    private int threadNo;
    public Consumer (BlockingQueue<Integer> sharedQueue,int threadNo) {
        this.sharedQueue = sharedQueue;

               err.printStackTrace();
            }
        }

Note. If you don't need multiple Producers and Consumers, keep single Producer and Consumer. I have added multiple Producers and Consumers to showcase capabilities of BlockingQueue among multiple Producers and Consumers.

The correct way would be:

location / {
    rewrite (.*) base.html last;
}

Using last will make nginx find a new suitable location block according to the result of rewriting.

try_files is also a perfectly valid approach to this problem.

Just throw it on cat, which line-wraps automatically

In the past I have used HttpUtility.HtmlEncode to encode text for xml. It performs the same task, really. I havent ran into any issues with it yet, but that's not to say I won't in the future. As the name implies, it was made for HTML, not XML.

You've probably already read it, but here is an article on xml encoding and decoding.

EDIT: Of course, if you use an xmlwriter or one of the new XElement classes, this encoding is done for you. In fact, you could just take the text, place it in a new XElement instance, then return the string (.tostring) version of the element. I've heard that SecurityElement.Escape will perform the same task as your utility method as well, but havent read much about it or used it.

EDIT2: Disregard my comment about XElement, since you're still on 2.0

You can always disable the use of pre-compiled headers in the project settings.

Instructions for VS 2010 (should be similar for other versions of VS):

Select your project, use the "Project -> Properties" menu and go to the "Configuration Properties -> C/C++ -> Precompiled Headers" section, then change the "Precompiled Header" setting to "Not Using Precompiled Headers" option.

If you are only trying to setup a minimal Visual Studio project for simple C++ command-line programs (such as those developed in introductory C++ programming classes), you can create an empty C++ project.

Like this,

Random random = new Random();
int randomNumber = random.nextInt(upperBound - lowerBound) + lowerBound;

This is a common problem in web applications which employ JavaScript namespacing. When this is the case, the problem 99.9% of the time is IE's inability to bind methods within the current namespace to the "this" keyword.

For example, if I have the JS namespace "StackOverflow" with the method "isAwesome". Normally, if you are within the "StackOverflow" namespace you can invoke the "isAwesome" method with the following syntax:

this.isAwesome();

Chrome, Firefox and Opera will happily accept this syntax. IE on the other hand, will not. Thus, the safest bet when using JS namespacing is to always prefix with the actual namespace. A la:

StackOverflow.isAwesome();

SELECT 'Free &' || ' Clear' FROM DUAL;

you can do something like adding a class to add border radius

HTML:

<a href="#" class="btn btn-default btn-circle"><i class="fa fa-user"></i></a>

CSS:

.btn-circle {
  width: 30px;
  height: 30px;
  text-align: center;
  padding: 6px 0;
  font-size: 12px;
  line-height: 1.42;
  border-radius: 15px;
}

in case you wanted to change dimension you need to change the font size or padding accordingly

Use the Google Guava API's join method:

Joiner.on(",").join(collectionOfStrings);

Coinbase has a REST API that gives you access to historical prices from their website. The data seems to show the Coinbase spot price (in USD) about every ten minutes.

Results are returned in CSV format. You must query the page number you want through the API. There are 1000 results (or price points) per page. That's about 7 days' worth of data per page.

You can do that by simply adding new elements to the array with the help of the push() method.

let colors = ["Red", "Blue", "Orange"];
console.log('Array before push: ' + colors);
// append new value to the array
colors.push("Green");
console.log('Array after push : ' + colors);

Another method is used for appending an element to the beginning of an array is the unshift() function, which adds and returns the new length. It accepts multiple arguments, attaches the indexes of existing elements, and finally returns the new length of an array:

let colors = ["Red", "Blue", "Orange"];
console.log('Array before unshift: ' + colors);
// append new value to the array
colors.unshift("Black", "Green");
console.log('Array after unshift : ' + colors);

There are other methods too. You can check them out here.

Get First Day of Last Month

Select ADDDATE(LAST_DAY(ADDDATE(now(), INTERVAL -2 MONTH)), INTERVAL 1 DAY);

Get Last Day of Last Month

Select LAST_DAY(ADDDATE(now(), INTERVAL -1 MONTH));

It works in both browsers if you use scrollTop() with 'document':

$(document).scrollTop();

...instead of 'html' or 'body'. Other way it won't work at the same time in both browsers.

Try turning the IEnumerable into a List. From this point on you will be able to use List's Remove method to remove items.

To pass it as a param to the Remove method using Linq you can get the item by the following methods:

• users.Single(x => x.userId == 1123)
• users.First(x => x.userId == 1123)

The code is as follows:

users = users.ToList(); // Get IEnumerable as List

users.Remove(users.First(x => x.userId == 1123)); // Remove item

// Finished

Try adding this:

$mail->SMTPAuth   = true;
$mail->SMTPSecure = "tls";

By looking at your debug logs, you can notice that the failing PhpMailer log shows this:

(..snip..)
SMTP -> ERROR: AUTH not accepted from server: 250 orion.bommtempo.net.br Hello admin-teste.bommtempo.com.br [200.155.129.6]
(..snip..)
503 AUTH command used when not advertised
(..snip..)

While your successful PEAR log shows this:

DEBUG: Send: STARTTLS
DEBUG: Recv: 220 TLS go ahead

My guess is that explicitly asking PHPMailer to use TLS will put it on the right track.
Also, make sure you're using the latest versin of PHPMailer.

use the int function to help

intchecker = float(input('Please enter a integer: '))
intcheck = 0
while intcheck != 1:
    if intchecker - int(intchecker) > 0:
        intchecker = float(input("You didn't enter a integer. "
                                 "Please enter a integer: "))
    else:
        intcheck = 1
print('you have entered a integer')

1. Why is this happening?

   The entire ext/mysql PHP extension, which provides all functions named with the prefix mysql_, was officially deprecated in PHP v5.5.0 and removed in PHP v7.

   It was originally introduced in PHP v2.0 (November 1997) for MySQL v3.20, and no new features have been added since 2006. Coupled with the lack of new features are difficulties in maintaining such old code amidst complex security vulnerabilities.

   The manual has contained warnings against its use in new code since June 2011.

2. How can I fix it?

   As the error message suggests, there are two other MySQL extensions that you can consider: MySQLi and PDO_MySQL, either of which can be used instead of ext/mysql. Both have been in PHP core since v5.0, so if you're using a version that is throwing these deprecation errors then you can almost certainly just start using them right away—i.e. without any installation effort.

   They differ slightly, but offer a number of advantages over the old extension including API support for transactions, stored procedures and prepared statements (thereby providing the best way to defeat SQL injection attacks). PHP developer Ulf Wendel has written a thorough comparison of the features.

   Hashphp.org has an excellent tutorial on migrating from ext/mysql to PDO.

3. I understand that it's possible to suppress deprecation errors by setting error_reporting in php.ini to exclude E_DEPRECATED:

   error_reporting = E_ALL ^ E_DEPRECATED
   

   What will happen if I do that?

   Yes, it is possible to suppress such error messages and continue using the old ext/mysql extension for the time being. But you really shouldn't do this—this is a final warning from the developers that the extension may not be bundled with future versions of PHP (indeed, as already mentioned, it has been removed from PHP v7). Instead, you should take this opportunity to migrate your application now, before it's too late.

   Note also that this technique will suppress all E_DEPRECATED messages, not just those to do with the ext/mysql extension: therefore you may be unaware of other upcoming changes to PHP that would affect your application code. It is, of course, possible to only suppress errors that arise on the expression at issue by using PHP's error control operator—i.e. prepending the relevant line with @—however this will suppress all errors raised by that expression, not just E_DEPRECATED ones.

What should you do?

• You are starting a new project.

  There is absolutely no reason to use ext/mysql—choose one of the other, more modern, extensions instead and reap the rewards of the benefits they offer.

• You have (your own) legacy codebase that currently depends upon ext/mysql.

  It would be wise to perform regression testing: you really shouldn't be changing anything (especially upgrading PHP) until you have identified all of the potential areas of impact, planned around each of them and then thoroughly tested your solution in a staging environment.

  • Following good coding practice, your application was developed in a loosely integrated/modular fashion and the database access methods are all self-contained in one place that can easily be swapped out for one of the new extensions.

    Spend half an hour rewriting this module to use one of the other, more modern, extensions; test thoroughly. You can later introduce further refinements to reap the rewards of the benefits they offer.

  • The database access methods are scattered all over the place and cannot easily be swapped out for one of the new extensions.

    Consider whether you really need to upgrade to PHP v5.5 at this time.

    You should begin planning to replace ext/mysql with one of the other, more modern, extensions in order that you can reap the rewards of the benefits they offer; you might also use it as an opportunity to refactor your database access methods into a more modular structure.

    However, if you have an urgent need to upgrade PHP right away, you might consider suppressing deprecation errors for the time being: but first be sure to identify any other deprecation errors that are also being thrown.

• You are using a third party project that depends upon ext/mysql.

  Consider whether you really need to upgrade to PHP v5.5 at this time.

  Check whether the developer has released any fixes, workarounds or guidance in relation to this specific issue; or, if not, pressure them to do so by bringing this matter to their attention. If you have an urgent need to upgrade PHP right away, you might consider suppressing deprecation errors for the time being: but first be sure to identify any other deprecation errors that are also being thrown.

  It is absolutely essential to perform regression testing.

Until PHP 5.3 release don't expect to have a good ORM. It's a OO limitation of PHP.

pygame.key.get_pressed() returns a list with the state of each key. If a key is held down, the state for the key is True, otherwise False. Use pygame.key.get_pressed() to evaluate the current state of a button and get continuous movement:

while True:

    pressed_key= pygame.key.get_pressed()
    x += (keys[pygame.K_RIGHT] - keys[pygame.K_LEFT]) * speed
    y += (keys[pygame.K_DOWN] - keys[pygame.K_UP]) * speed

The keyboard events (see pygame.event module) occur only once when the state of a key changes. The KEYDOWN event occurs once every time a key is pressed. KEYUP occurs once every time a key is released. Use the keyboard events for a single action or movement:

while True:

    for event in pygame.event.get():
        if event.type == pygame.KEYDOWN:
            if event.key == pygame.K_LEFT:
                x -= speed
            if event.key == pygame.K_RIGHT:
                x += speed
            if event.key == pygame.K_UP:
                y -= speed
            if event.key == pygame.K_DOWN:
                y += speed

After spending hours, this neatly helped me to solve my problem:

Yes, you can run commands on the Ansible host. You can specify that all tasks in a play run on the Ansible host, or you can mark individual tasks to run on the Ansible host.

If you want to run an entire play on the Ansible host, then specify hosts: 127.0.0.1 and connection:local in the play, for example:

- name: a play that runs entirely on the ansible host
  hosts: 127.0.0.1
  connection: local
  tasks:
  - name: check out a git repository
    git: repo=git://foosball.example.org/path/to/repo.git dest=/local/path

See Local Playbooks in the Ansible documentation for more details.

If you just want to run a single task on your Ansible host, you can use local_action to specify that a task should be run locally. For example:

- name: an example playbook
  hosts: webservers
  tasks:
  - ...

  - name: check out a git repository
    local_action: git repo=git://foosball.example.org/path/to/repo.git dest=/local/path

See Delegation in the Ansible documentation for more details.

Edit: You can avoid having to type connection: local in your play by adding this to your inventory:

localhost ansible_connection=local

(Here you'd use "localhost" instead of "127.0.0.1" to refer to the play).

Edit: In newer versions of ansible, you no longer need to add the above line to your inventory, ansible assumes it's already there.

I got here searching for a way to execute some code whenever the program ends.
Found this:

Kernel.at_exit { puts "sayonara" }
# do whatever
# [...]
# call #exit or #abort or just let the program end
# calling #exit! will skip the call

Called multiple times will register multiple handlers.

You can delete files in PHP using the unlink() function.

unlink('path/to/file.jpg');

Your main() method is static, but it is referencing two non-static members: con2 and getConnectionUrl2(). You need to do one of three things:

1) Make con2 and getConnectionUrl2() static.

2) Inside main(), create an instance of class testconnect and access con2 and getConnectionUrl2() off of that.

3) Break out a different class to hold con2 and getConnectionUrl2() so that testconnect only has main in it. It will still need to instantiate the different class and call the methods off that.

Option #3 is the best option. #1 is the worst.

But, you cannot access non-static members from within a static method.

Try:

0 */6 * * * command

. * has to

You have to hide the column at the grid view control rather than at the data source. Hiding it at the data source it will not render to the grid view at all, therefore you won't be able to access the value in the grid view. Doing it the way you're suggesting, you would have to access the column value through the data source as opposed to the grid view.

To hide the column on the grid view control, you can use code like this:

dataGridView1.Columns[0].Visible = false;

To access the column from the data source, you could try something like this:

object colValue = ((DataTable)dataGridView.DataSource).Rows[dataSetIndex]["ColumnName"];

If you prefer to avoid a web service, you can retrieve that information from the browser like this:

var d = new Date();
var usertime = d.toLocaleString();

//some browsers / OSs provide the timezone name in their local string
var tzsregex = /\b(ACDT|ACST|ACT|ADT|AEDT|AEST|AFT|AKDT|AKST|AMST|AMT|ART|AST|AWDT|AWST|AZOST|AZT|BDT|BIOT|BIT|BOT|BRT|BST|BTT|CAT|CCT|CDT|CEDT|CEST|CET|CHADT|CHAST|CIST|CKT|CLST|CLT|COST|COT|CST|CT|CVT|CXT|CHST|DFT|EAST|EAT|ECT|EDT|EEDT|EEST|EET|EST|FJT|FKST|FKT|GALT|GET|GFT|GILT|GIT|GMT|GST|GYT|HADT|HAEC|HAST|HKT|HMT|HST|ICT|IDT|IRKT|IRST|IST|JST|KRAT|KST|LHST|LINT|MART|MAGT|MDT|MET|MEST|MIT|MSD|MSK|MST|MUT|MYT|NDT|NFT|NPT|NST|NT|NZDT|NZST|OMST|PDT|PETT|PHOT|PKT|PST|RET|SAMT|SAST|SBT|SCT|SGT|SLT|SST|TAHT|THA|UYST|UYT|VET|VLAT|WAT|WEDT|WEST|WET|WST|YAKT|YEKT)\b/gi;

//in other browsers the timezone needs to be estimated based on the offset
var timezonenames = {"UTC+0":"GMT","UTC+1":"CET","UTC+2":"EET","UTC+3":"EEDT","UTC+3.5":"IRST","UTC+4":"MSD","UTC+4.5":"AFT","UTC+5":"PKT","UTC+5.5":"IST","UTC+6":"BST","UTC+6.5":"MST","UTC+7":"THA","UTC+8":"AWST","UTC+9":"AWDT","UTC+9.5":"ACST","UTC+10":"AEST","UTC+10.5":"ACDT","UTC+11":"AEDT","UTC+11.5":"NFT","UTC+12":"NZST","UTC-1":"AZOST","UTC-2":"GST","UTC-3":"BRT","UTC-3.5":"NST","UTC-4":"CLT","UTC-4.5":"VET","UTC-5":"EST","UTC-6":"CST","UTC-7":"MST","UTC-8":"PST","UTC-9":"AKST","UTC-9.5":"MIT","UTC-10":"HST","UTC-11":"SST","UTC-12":"BIT"};

var timezone = usertime.match(tzsregex);
if (timezone) {
    timezone = timezone[timezone.length-1];
} else {
    var offset = -1*d.getTimezoneOffset()/60;
    offset = "UTC" + (offset >= 0 ? "+" + offset : offset);
    timezone = timezonenames[offset];
}

//there are 3 variables can use to see the timezone
// usertime - full date
// offset - UTC offset time
// timezone - country

console.log('Full Date: ' + usertime);
console.log('UTC Offset: ' + offset);
console.log('Country Code Timezone: ' + timezone);

In my current case it is printing:

Full Date: ?27?/?01?/?2014? ?16?:?53?:?37 UTC Offset: UTC-3 Country Code Timezone: BRT

Hope it can be helpful.

If your using ASP.Net 5 (now known as ASP.Net Core v1) ensure in your project.json "commands" section for each site you are hosting that the Kestrel proxy listening port differs between sites, otherwise one site will work but the other will return a 504 gateway timeout.

 "commands": {
    "web": "Microsoft.AspNet.Server.Kestrel --server.urls http://localhost:5090"

As has been suggested at least twice, you can use descendingIterator with a Deque, in particular with a LinkedList. If you want to use the for-each loop (i.e., have an Iterable), you can construct and use a wraper like this:

import java.util.*;

public class Main {

    public static class ReverseIterating<T> implements Iterable<T> {
        private final LinkedList<T> list;

        public ReverseIterating(LinkedList<T> list) {
            this.list = list;
        }

        @Override
        public Iterator<T> iterator() {
            return list.descendingIterator();
        }
    }

    public static void main(String... args) {
        LinkedList<String> list = new LinkedList<String>();
        list.add("A");
        list.add("B");
        list.add("C");
        list.add("D");
        list.add("E");

        for (String s : new ReverseIterating<String>(list)) {
            System.out.println(s);
        }
    }
}

Java Usage example: myMenuItem.setIcon(android.R.drawable.ic_menu_save);

Resource Usage example: android:icon="@android:drawable/ic_menu_save"

You can use max-height in an inline style attribute, as below:

<div class="panel panel-primary">
  <div class="panel-heading">jhdsahfjhdfhs</div>
  <div class="panel-body" style="max-height: 10;">fdoinfds sdofjohisdfj</div>
</div>

To use scrolling with content that overflows a given max-height, you can alternatively try the following:

<div class="panel panel-primary">
  <div class="panel-heading">jhdsahfjhdfhs</div>
  <div class="panel-body" style="max-height: 10;overflow-y: scroll;">fdoinfds sdofjohisdfj</div>
</div>

To restrict the height to a fixed value you can use something like this.

<div class="panel panel-primary">
  <div class="panel-heading">jhdsahfjhdfhs</div>
  <div class="panel-body" style="min-height: 10; max-height: 10;">fdoinfds sdofjohisdfj</div>
</div>

Specify the same value for both max-height and min-height (either in pixels or in points – as long as it’s consistent).

You can also put the same styles in css class in a stylesheet (or a style tag as shown below) and then include the same in your tag. See below:

Style Code:

.fixed-panel {
  min-height: 10;
  max-height: 10;
  overflow-y: scroll;
}

Apply Style :

<div class="panel panel-primary">
  <div class="panel-heading">jhdsahfjhdfhs</div>
  <div class="panel-body fixed-panel">fdoinfds sdofjohisdfj</div>
</div>

Hope this helps with your need.

The absolute divs are taken out of the flow of the document so the containing div does not have any content except for the padding. Give #box a height to fill it out.

#box {
    background-color: #000;
    position: relative;
    padding: 10px;
    width: 220px;
    height:30px;
}

 if ($("#Password").val() != $("#ConfirmPassword").val()) {
          alert("Passwords do not match.");
      }

A JQuery approach that will eliminate needless code.

Window.load (as opposed to document.ready()) appears to the be the trick used in the JSFiddler onload demos of Fancybox 2.0:

$(window).load(function()
{
    $.fancybox("test");
});

Bare in mind you may be using document.ready() elsewhere, and IE9 gets upset with the load order of the two. This leaves you with two options: change everything to window.load or use a setTimer().

Introduction

Your title “Keep Me Logged In” - the best approach make it difficult for me to know where to start because if you are looking at best approach then you would have to consideration the following :

• Identification
• Security

Cookies

Cookies are vulnerable, Between common browser cookie-theft vulnerabilities and cross-site scripting attacks we must accept that cookies are not safe. To help improve security you must note that php setcookies has additional functionality such as

bool setcookie ( string $name [, string $value [, int $expire = 0 [, string $path [, string $domain [, bool $secure = false [, bool $httponly = false ]]]]]] )

• secure (Using HTTPS connection)
• httponly (Reduce identity theft through XSS attack)

Definitions

• Token ( Unpredictable random string of n length eg. /dev/urandom)
• Reference ( Unpredictable random string of n length eg. /dev/urandom)
• Signature (Generate a keyed hash value using the HMAC method)

Simple Approach

A simple solution would be :

• User is logged on with Remember Me
• Login Cookie issued with token & Signature
• When is returning, Signature is checked
• If Signature is ok .. then username & token is looked up in the database
• if not valid .. return to login page
• If valid automatically login

The above case study summarizes all example given on this page but they disadvantages is that

• There is no way to know if the cookies was stolen
• Attacker may be access sensitive operations such as change of password or data such as personal and baking information etc.
• The compromised cookie would still be valid for the cookie life span

Better Solution

A better solution would be

• User is logged in and remember me is selected
• Generate Token & signature and store in cookie
• The tokens are random and are only valid for single autentication
• The token are replace on each visit to the site
• When a non-logged user visit the site the signature, token and username are verified
• Remember me login should have limited access and not allow modification of password, personal information etc.

Example Code

// Set privateKey
// This should be saved securely 
$key = 'fc4d57ed55a78de1a7b31e711866ef5a2848442349f52cd470008f6d30d47282';
$key = pack("H*", $key); // They key is used in binary form

// Am Using Memecahe as Sample Database
$db = new Memcache();
$db->addserver("127.0.0.1");

try {
    // Start Remember Me
    $rememberMe = new RememberMe($key);
    $rememberMe->setDB($db); // set example database

    // Check if remember me is present
    if ($data = $rememberMe->auth()) {
        printf("Returning User %s\n", $data['user']);

        // Limit Acces Level
        // Disable Change of password and private information etc

    } else {
        // Sample user
        $user = "baba";

        // Do normal login
        $rememberMe->remember($user);
        printf("New Account %s\n", $user);
    }
} catch (Exception $e) {
    printf("#Error  %s\n", $e->getMessage());
}

Class Used

Testing in Firefox & Chrome

Advantage

• Better Security
• Limited access for attacker
• When cookie is stolen its only valid for single access
• When next the original user access the site you can automatically detect and notify the user of theft

Disadvantage

• Does not support persistent connection via multiple browser (Mobile & Web)
• The cookie can still be stolen because the user only gets the notification after the next login.

Quick Fix

• Introduction of approval system for each system that must have persistent connection
• Use multiple cookies for the authentication

Multiple Cookie Approach

When an attacker is about to steal cookies the only focus it on a particular website or domain eg. example.com

But really you can authenticate a user from 2 different domains (example.com & fakeaddsite.com) and make it look like "Advert Cookie"

• User Logged on to example.com with remember me
• Store username, token, reference in cookie
• Store username, token, reference in Database eg. Memcache
• Send refrence id via get and iframe to fakeaddsite.com
• fakeaddsite.com uses the reference to fetch user & token from Database
• fakeaddsite.com stores the signature
• When a user is returning fetch signature information with iframe from fakeaddsite.com
• Combine it data and do the validation
• ..... you know the remaining

Some people might wonder how can you use 2 different cookies ? Well its possible, imagine example.com = localhost and fakeaddsite.com = 192.168.1.120. If you inspect the cookies it would look like this

From the image above

• The current site visited is localhost
• It also contains cookies set from 192.168.1.120

192.168.1.120

• Only accepts defined HTTP_REFERER
• Only accepts connection from specified REMOTE_ADDR
• No JavaScript, No content but consist nothing rather than sign information and add or retrieve it from cookie

Advantage

• 99% percent of the time you have tricked the attacker
• You can easily lock the account in the attacker first attempt
• Attack can be prevented even before the next login like the other methods

Disadvantage

• Multiple Request to server just for a single login

Improvement

• Done use iframe use ajax

You need to put the entire ternary expression in parenthesis. Unfortunately that means you can't use "@:", but you could do something like this:

@(deletedView ? "Deleted" : "Created by")

Razor currently supports a subset of C# expressions without using @() and unfortunately, ternary operators are not part of that set.

var fs = require("fs");
var filename = "./index.html";

function start(resp) {
    resp.writeHead(200, {
        "Content-Type": "text/html"
    });
    fs.readFile(filename, "utf8", function(err, data) {
        if (err) throw err;
        resp.write(data);
        resp.end();
    });
}

?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#FFFFFF"
android:id="@+id/myScreen"
</LinearLayout>

In other words, "android:background" is the tag in the XML you want to change.

If you need to dynamically update the background value, see the following:

Exercise: Change background color, by SeekBar

declare @dt1 datetime='2012/06/13 08:11:12', @dt2 datetime='2012/06/12 02:11:12'

select CAST((@dt2-@dt1) as time(0))

With standart binding you need to use converters that looks little windy. So, I recommend you to look at my project CalcBinding, which was developed specially to resolve this problem and some others. With advanced binding you can write expressions with many source properties directly in xaml. Say, you can write something like:

<Button IsEnabled="{c:Binding Path=!IsReadOnly}" />

or

<Button Content="{c:Binding ElementName=grid, Path=ActualWidth+Height}"/>

or

<Label Content="{c:Binding A+B+C }" />

or

<Button Visibility="{c:Binding IsChecked, FalseToVisibility=Hidden}" />

where A, B, C, IsChecked - properties of viewModel and it will work properly

_ Alias for gettext()

The underscore character '_' as in _() is an alias to the gettext() function.

Starting with matplotlib 1.4.0 there is now an an interactive backend for use in the notebook

%matplotlib notebook

There are a few version of IPython which do not have that alias registered, the fall back is:

%matplotlib nbagg

If that does not work update you IPython.

To play with this, goto tmpnb.org

and paste

%matplotlib notebook

import pandas as pd
import numpy as np
import matplotlib

from matplotlib import pyplot as plt
import seaborn as sns

ts = pd.Series(np.random.randn(1000), index=pd.date_range('1/1/2000', periods=1000))
ts = ts.cumsum()

df = pd.DataFrame(np.random.randn(1000, 4), index=ts.index,
                  columns=['A', 'B', 'C', 'D'])
df = df.cumsum()
df.plot(); plt.legend(loc='best')    

into a code cell (or just modify the existing python demo notebook)

The --download-cache option should do what you want:

pip install --download-cache="/pth/to/downloaded/files" package

However, when I tested this, the main package downloaded, saved and installed ok, but the the dependencies were saved with their full url path as the name - a bit annoying, but all the tar.gz files were there.

The --download option downloads the main package and its dependencies and does not install any of them. (Note that prior to version 1.1 the --download option did not download dependencies.)

pip install package --download="/pth/to/downloaded/files"

The pip documentation outlines using --download for fast & local installs.

You should also use the style 'color' and not 'font-color'

<?php

foreach($months as $key => $month){
  if(strpos($filename,$month)!==false){
        echo "<style = 'color: #ff0000;'> Movie List for {$key} 2013 </style>";
    }
}

?>

In general, the comments on double and single quotes are correct in other suggestions. $Variables only execute in double quotes.

var newElementsAppended = $(newHtml).appendTo("#myDiv");
newElementsAppended.effects("highlight", {}, 2000);

Show as decimal Select ifnull(format(100.00, 1, 'en_US'), 0) 100.0

Show as Percentage Select concat(ifnull(format(100.00, 0, 'en_US'), 0), '%') 100%

There is a much simpler solution for that.
Actually treating the items of JArray as JObject works.
Here is an example:
Let's say we have such array of JSON objects:

JArray jArray = JArray.Parse(@"[
              {
                ""name"": ""Croke Park II"",
                ""url"": ""http://twitter.com/search?q=%22Croke+Park+II%22"",
                ""promoted_content"": null,
                ""query"": ""%22Croke+Park+II%22"",
                ""events"": null
              },
              {
                ""name"": ""Siptu"",
                ""url"": ""http://twitter.com/search?q=Siptu"",
                ""promoted_content"": null,
                ""query"": ""Siptu"",
                ""events"": null
              }]");

To get access each item we just do the following:

foreach (JObject item in jArray)
{
    string name = item.GetValue("name").ToString();
    string url = item.GetValue("url").ToString();
    // ...
}

As the question seems unclear, I'm sorry if this answer is not directly related to the original intent.

For those using Select2 version 4+ and according to official plugin documentation, .select2("enable")is not the way to go anymore for disabling the select box (not a single option of it). It will even be completely removed from version 4.1 onward.

Quoted directy from the documentation (see https://select2.org/upgrading/migrating-from-35#select2-enable):

Select2 will respect the disabled property of the underlying select element. In order to enable or disable Select2, you should call .prop('disabled', true/false) on the element. Support for the old methods will be completely removed in Select2 4.1.

So in the previous answer's example, it should be: $('select').prop(disabled,true);

Case 1

INSERT INTO tab_student (name_student, id_teacher_fk)
    VALUES ('dan red', 
           (SELECT id_teacher FROM tab_teacher WHERE name_teacher ='jason bourne')

it is advisable to store your values in lowercase to make retrieval easier and less error prone

Case 2

mysql docs

INSERT INTO tab_teacher (name_teacher) 
    VALUES ('tom stills')
INSERT INTO tab_student (name_student, id_teacher_fk)
    VALUES ('rich man', LAST_INSERT_ID())

You can specify JsonSerializerSettings for each JsonConvert, and you can set a global default.

Single JsonConvert with an overload:

// Option #1.
JsonSerializerSettings config = new JsonSerializerSettings { ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore };
this.json = JsonConvert.SerializeObject(YourObject, Formatting.Indented, config);

// Option #2 (inline).
JsonConvert.SerializeObject(YourObject, Formatting.Indented,
    new JsonSerializerSettings() {
        ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore
    }
);

Global Setting with code in Application_Start() in Global.asax.cs:

JsonConvert.DefaultSettings = () => new JsonSerializerSettings {
     Formatting = Newtonsoft.Json.Formatting.Indented,
     ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore
};

Reference: https://github.com/JamesNK/Newtonsoft.Json/issues/78

For ASP.NET MVC if you want to make an exception for leaving the page via submitting a particular form:

Set a form id:

@using (Html.BeginForm("Create", "MgtJob", FormMethod.Post, new { id = "createjob" }))
{
  // Your code
}



<script type="text/javascript">

  // Without submit form
   $(window).bind('beforeunload', function () {
        if ($('input').val() !== '') {
            return "It looks like you have input you haven't submitted."
        }
    });

    // this will call before submit; and it will unbind beforeunload
    $(function () {
        $("#createjob").submit(function (event) {
            $(window).unbind("beforeunload");
        });
    });

</script>

Yep, you are right, these are oop constructs.

__init__ is the constructor for a class. The self parameter refers to the instance of the object (like this in C++).

class Point:
    def __init__(self, x, y):
        self._x = x
        self._y = y

The __init__ method gets called when memory for the object is allocated:

x = Point(1,2)

It is important to use the self parameter inside an object's method if you want to persist the value with the object. If, for instance, you implement the __init__ method like this:

class Point:
    def __init__(self, x, y):
        _x = x
        _y = y

Your x and y parameters would be stored in variables on the stack and would be discarded when the init method goes out of scope. Setting those variables as self._x and self._y sets those variables as members of the Point object (accessible for the lifetime of the object).

The pythonic way to read a file and put every lines in a list:

from __future__ import with_statement #for python 2.5
with open('C:/path/numbers.txt', 'r') as f:
    lines = f.readlines()

Then, assuming that each lines contains a number,

numbers =[int(e.strip()) for e in lines]

If it matters whether the file you're looking for is a directory and not just a file, you could use File.directory? or Dir.exist?. This will return true only if the file exists and is a directory.

As an aside, a more idiomatic way to write the method would be to take advantage of the fact that Ruby automatically returns the result of the last expression inside the method. Thus, you could write it like this:

def directory_exists?(directory)
  File.directory?(directory)
end

Note that using a method is not necessary in the present case.

This works on a Mac as noted by Alex Moore-Niemi:

set backupdir=$TMPDIR//
set directory=$TMPDIR//

Make sure to use TMPDIR and not TEMPDIR.

The easiest way is to use Resource Manager

Then you can select each density

And after importing you can see the 6 different versions of this image

You should use something similar to this for adding TextView to LinearLayout dynamically:

LinearLayout linearLayout = getActivity().findViewById(R.id.infoLayout);

TextView valueTV = new TextView(context);
valueTV.setText("hallo hallo");
valueTV.setId(Integer.parseInt("5"));
valueTV.setLayoutParams(new LinearLayout.LayoutParams(
       LinearLayout.LayoutParams.FILL_PARENT,
       LinearLayout.LayoutParams.WRAP_CONTENT));

linearLayout.addView(valueTV);

getActivity() is used for inside Fragments, you can use context or anything similar per each instance you are inside.

UNIX filesystems (generally) don't store creation times. Instead, there are only access time, (data) modification time, and (inode) change time.

That being said, find has -atime -mtime -ctime predicates:

$ man 1 find
...
-ctime  n
        The primary shall evaluate as true if the time of last change of
        file status information subtracted from the initialization time,
        divided by 86400 (with any remainder discarded), is n.
...

Thus find -ctime 0 finds everything for which the inode has changed (e.g. includes file creation, but also counts link count and permissions and filesize change) less than an hour ago.

-(BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string {
    if (textField.text.length >= 50) {
        return NO;
    }
    return YES;
}

One peculiarity of the do while is that you need a semi-colon after the while to complete. It is often used in macro definitions to execute several statements only once while constraining the impact of the macro. If macros where defined as blocks, some parsing errors may occur.

One explanation among others

If you want to make a diff against current branch you can ommit it and use:

git diff $BRANCH -- path/to/file

this way it will diff from current branch to the referenced branch ($BRANCH).

Eclipse hooks Dynamic Web projects into tomcat and maintains it's own configuration but does not deploy the standard tomcat ROOT.war. As http://localhost:8085/ link returns 404 does indeed show that tomcat is up and running, just can't find a web app deployed to root.

By default, any deployed dynamic web projects use their project name as context root, so you should see http://localhost:8085/yourprojectname working properly, but check the Servers tab first to ensure that your web project has actually been deployed.

Hope that helps.

If it's open to a modification, you could use a suffix instead of a prefix. Then you could use tab-completion to get the original filename and add the suffix.

Otherwise, no this isn't something that is supported by the mv command. A simple shell script could cope though.

I think this would do it:

<html>
<head>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.0/jquery.min.js"></script>
<script type="text/javascript">
    $(document).ready(function(){

         $(".divlink").click(function(){
         $("#content").attr("src" , $(this).attr("ref"));

});

});
</script>

By the way if you can avoid Jquery, you can just use the target attribute of <a> element:

<html>
<body>
<iframe id="content" name="content"></iframe>

<a href="page1.html" target="content" >Page 1</a><br />
<a href="page2.html" target="content" >Page 2</a><br />
<a href="page3.html" target="content" >Page 3</a><br />
<a href="page4.html" target="content" >Page 4</a><br />
<a href="page5.html" target="content" >Page 5</a><br />
<a href="page6.html" target="content" >Page 6</a><br />
</body>
</html> 

Can you give this a try,

return View::make("user/regprofile", compact('students')); OR
return View::make("user/regprofile")->with(array('students'=>$students));

While, you can set multiple variables something like this,

$instructors="";
$instituitions="";

$compactData=array('students', 'instructors', 'instituitions');
$data=array('students'=>$students, 'instructors'=>$instructors, 'instituitions'=>$instituitions);

return View::make("user/regprofile", compact($compactData));
return View::make("user/regprofile")->with($data);

Try this jQuery which works in IE9, FF, Chrome and provides a countdown to users:

$("#comments").bind("keyup keydown", function() {
    var max = 500;
    var value = $(this).val();
    var left = max - value.length;
    if(left < 0) {
        $(this).val( value.slice(0, left) );
        left = 0;
    }
    $("#charcount").text(left);
}); 

<textarea id="comments" onkeyup="ismaxlength(this,500)"></textarea>
<span class="max-char-limit"><span id="charcount">500</span> characters left</span>

Indeed, just as commented by Tim Williams, the way to make it work is pre-formatting as text. Thus, to do it all via VBA, just do that:

Cells(1, 1).NumberFormat = "@"
Cells(1, 1).Value = "1234,56"

I think this should do it:

var ct = $('#mylist').children().size(); 

try the following:

 myPictureBox.Image = global::mynamespace.Properties.Resources.photo1;

and replace namespace with your project namespace

If you need in different Layer :

Create a Static Class and expose all config properties on that layer as below :

using Microsoft.Extensions.Configuration;_x000D_
using System.IO;_x000D_
_x000D_
namespace Core.DAL_x000D_
{_x000D_
    public static class ConfigSettings_x000D_
    {_x000D_
        public static string conStr1 { get ; }_x000D_
        static ConfigSettings()_x000D_
        {_x000D_
            var configurationBuilder = new ConfigurationBuilder();_x000D_
            string path = Path.Combine(Directory.GetCurrentDirectory(), "appsettings.json");_x000D_
            configurationBuilder.AddJsonFile(path, false);_x000D_
            conStr1 = configurationBuilder.Build().GetSection("ConnectionStrings:ConStr1").Value;_x000D_
        }_x000D_
    }_x000D_
}

You can use the strip() function to remove trailing (and leading) whitespace; passing it an argument will let you specify which whitespace:

for i in range(len(lists)):
    grades.append(lists[i].strip('\n'))

It looks like you can just simplify the whole block though, since if your file stores one ID per line grades is just lists with newlines stripped:

Before

lists = files.readlines()
grades = []

for i in range(len(lists)):
    grades.append(lists[i].split(","))

After

grades = [x.strip() for x in files.readlines()]

(the above is a list comprehension)

Finally, you can loop over a list directly, instead of using an index:

Before

for i in range(len(grades)):
    # do something with grades[i]

After

for thisGrade in grades:
    # do something with thisGrade

Checkout intent properties like no history , clear back stack etc ... Intent.setFlags

Intent mStartActivity = new Intent(HomeActivity.this, SplashScreen.class);
int mPendingIntentId = 123456;
PendingIntent mPendingIntent = PendingIntent.getActivity(HomeActivity.this, mPendingIntentId, mStartActivity,
PendingIntent.FLAG_CANCEL_CURRENT);
AlarmManager mgr = (AlarmManager) HomeActivity.this.getSystemService(Context.ALARM_SERVICE);
mgr.set(AlarmManager.RTC, System.currentTimeMillis() + 100, mPendingIntent);
System.exit(0);

Let's look at this with the help of an example. Suppose we have a direct mapped cache and the write back policy is used. So we have a valid bit, a dirty bit, a tag and a data field in a cache line. Suppose we have an operation : write A ( where A is mapped to the first line of the cache).

What happens is that the data(A) from the processor gets written to the first line of the cache. The valid bit and tag bits are set. The dirty bit is set to 1.

Dirty bit simply indicates was the cache line ever written since it was last brought into the cache!

Now suppose another operation is performed : read E(where E is also mapped to the first cache line)

Since we have direct mapped cache, the first line can simply be replaced by the E block which will be brought from memory. But since the block last written into the line (block A) is not yet written into the memory(indicated by the dirty bit), so the cache controller will first issue a write back to the memory to transfer the block A to memory, then it will replace the line with block E by issuing a read operation to the memory. dirty bit is now set to 0.

So write back policy doesnot guarantee that the block will be the same in memory and its associated cache line. However whenever the line is about to be replaced, a write back is performed at first.

A write through policy is just the opposite. According to this, the memory will always have a up-to-date data. That is, if the cache block is written, the memory will also be written accordingly. (no use of dirty bits)

CODE

<?php

# setup test array.
$cats = array();
$cats[] = (object) array('id' => 15);
$cats[] = (object) array('id' => 18);
$cats[] = (object) array('id' => 23);

function extract_ids($array = array())
{
    $ids = array();
    foreach ($array as $object) {
        $ids[] = $object->id;
    }
    return $ids;
}

$cat_ids = extract_ids($cats);
var_dump($cats);
var_dump($cat_ids);

?>

OUTPUT

# var_dump($cats);
array(3) {
  [0]=>
  object(stdClass)#1 (1) {
    ["id"]=>
    int(15)
  }
  [1]=>
  object(stdClass)#2 (1) {
    ["id"]=>
    int(18)
  }
  [2]=>
  object(stdClass)#3 (1) {
    ["id"]=>
    int(23)
  }
}

# var_dump($cat_ids);
array(3) {
  [0]=>
  int(15)
  [1]=>
  int(18)

  int(23)
}

I know its using a loop, but it's the simplest way to do it! And using a function it still ends up on a single line.

I think is more robust to use regular expressions:

import re

for i, line in enumerate(content):
    print line if not (re.match('\r?\n', line)) else pass

This would match in Windows/unix. In addition if you are not sure about lines containing only space char you could use '\s*\r?\n' as expression

If you really want to understand ANSI C 89, I need to correct you in one thing; In ANSI C 89 the difference between the following functions:

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

is:

int main()

• a function that expects unknown number of arguments of unknown types. Returns an integer representing the application software status.

int main(void)

• a function that expects no arguments. Returns an integer representing the application software status.

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

• a function that expects argc number of arguments and argv[] arguments. Returns an integer representing the application software status.

About when using each of the functions

int main(void)

• you need to use this function when your program needs no initial parameters to run/ load (parameters received from the OS - out of the program it self).

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

• you need to use this function when your program needs initial parameters to load (parameters received from the OS - out of the program it self).

About void main()

In ANSI C 89, when using void main and compiling the project AS -ansi -pedantic (in Ubuntu, e.g) you will receive a warning indicating that your main function is of type void and not of type int, but you will be able to run the project. Most C developers tend to use int main() on all of its variants, though void main() will also compile.

Here's the definitive solution that merges all other answers. Features:

1. You can copy-paste the code into your shell or script.

2. You can use it as you like:

   >>> clear()
   >>> -clear
   >>> clear  # <- but this will only work on a shell
   

3. You can import it as a module:

   >>> from clear import clear
   >>> -clear
   

4. You can call it as a script:

   $ python clear.py
   

5. It is truly multiplatform; if it can't recognize your system
   (ce, nt, dos or posix) it will fall back to printing blank lines.

You can download the [full] file here: https://gist.github.com/3130325
Or if you are just looking for the code:

class clear:
 def __call__(self):
  import os
  if os.name==('ce','nt','dos'): os.system('cls')
  elif os.name=='posix': os.system('clear')
  else: print('\n'*120)
 def __neg__(self): self()
 def __repr__(self):
  self();return ''

clear=clear()

you don't need to create a hidden field for all checkboxes just copy my code. it will change the value of checkbox if not checked the value will assign 0 and if checkbox checked then assign value into 1

$("form").submit(function () {

    var this_master = $(this);

    this_master.find('input[type="checkbox"]').each( function () {
        var checkbox_this = $(this);


        if( checkbox_this.is(":checked") == true ) {
            checkbox_this.attr('value','1');
        } else {
            checkbox_this.prop('checked',true);
            //DONT' ITS JUST CHECK THE CHECKBOX TO SUBMIT FORM DATA    
            checkbox_this.attr('value','0');
        }
    })
})

Private Sub cmdClear_Click()
    ComboBox1.Value = Null
    ComboBox2.Value = Null
End Sub

As others have indicated, bash does not have built-in floating-point operators.

You can implement floating-point in bash, even without using calculator programs like bc and awk, or any external programs for that matter.

I'm doing exactly this in my project, shellmath, in three basic steps:

1. Break the numbers down into their integer and fractional parts
2. Use the built-in integer operators to process the parts separately while being careful about place-value and carrying
3. Recombine the results

As a teaser, I've added a demo script that calculates e using its Taylor series centered at x=0.

Please check it out if you have a moment. I welcome your feedback!

Because there are two print statements. First is inside function and second is outside function. When function not return any thing that time it return None value.

Use return statement at end of function to return value.

e.g.:

Return None value.

>>> def test1():
...    print "In function."
... 
>>> a = test1()
In function.
>>> print a
None
>>> 
>>> print test1()
In function.
None
>>>
>>> test1()
In function.
>>> 

Use return statement

>>> def test():
...   return "ACV"
... 
>>> print test()
ACV
>>> 
>>> a = test()
>>> print a
ACV
>>> 

You can just run:

git stash pop

and it will unstash your changes.

If you want to preserve the state of files (staged vs. working), use

git stash apply --index

There are a few problems here.

1: onBlur expects a callback, and you are calling renderPasswordConfirmError and using the return value, which is null.

2: you need a place to render the error.

3: you need a flag to track "and I validating", which you would set to true on blur. You can set this to false on focus if you want, depending on your desired behavior.

handleBlur: function () {
  this.setState({validating: true});
},
render: function () {
  return <div>
    ...
    <input
        type="password"
        placeholder="Password (confirm)"
        valueLink={this.linkState('password2')}
        onBlur={this.handleBlur}
     />
    ...
    {this.renderPasswordConfirmError()}
  </div>
},
renderPasswordConfirmError: function() {
  if (this.state.validating && this.state.password !== this.state.password2) {
    return (
      <div>
        <label className="error">Please enter the same password again.</label>
      </div>
    );
  }  
  return null;
},

I had the same problem in Xcode 11.5 after revoking a certificate through Apple's developer homepage and adding it again (even though it looked different afterwards):

Every time I tried to archive my app, it would fail at the very end (not the pods but my actual app) with the same PhaseScriptExecution failed with a nonzero exit code error message. There is/was a valid team with an "Apple Development" signing certificate in "Signing & Capabilities" (project file in Xcode) and locking & unlocking the keychain, cleaning & building the project, restarting,... didn't work.

The problem was caused by having two active certificates of the same type that I must have added on accident, in addition to the renewed one. I deleted both the renewed one and the duplicate and it worked again.

You can find your certificates here or find the page like this:

• https://developer.apple.com/
• "Account" (at the top)
• Log in
• "Certificates, IDs & Profiles" (on the left)

Also check that there aren't any duplicates in your keychain! Be careful though - don't delete or add anything unless you know what you're doing, otherwise you might create a huge mess!

I think this should work,

a = numpy.arange(0,27.,3).reshape(3,3)

a /=  a.sum(axis=1)[:,numpy.newaxis]

HTML5 is supported on both Google (android) phones such as Galaxy S, and iPhone. iPhone however doesn't support Flash, which Google phones do support.

You can do this in jquery by setting the attribute disabled to 'disabled'.

$(this).prop('disabled', true);

I have made a simple example http://jsfiddle.net/4gnXL/2/

The solution is well documented in the official docs: https://ipython.readthedocs.org/en/latest/install/kernel_install.html

I tried the first approach. Since I already had ipykernel installed, simply running python3 -m ipykernel install --user solved the problem.

I landed here with the same issue, then figured it out on my own. This weird character was appearing with my HTML.

The issue is most likely your code editor. I use Espresso and sometimes run into issues like this.

To fix it, simply highlight the affected code, then go to the menu and click "convert to numeric entities". You'll see the numeric value of this character appear; simply delete it and it's gone forever.

In my case the format changing did not help, nothing changed in the date representation whatever cell format I was selecting. However, I found that the correct date entry for 18.11.1999 when F2 pressed was 18 11 1999 - whith spaces, no dots! When I performed "search-replace" and changed dots with space, the problem was solved.

In any case, you can override height with max-height.

Adding to @MK Yung and @Bruno's answer.. Do enter a password for the destination keystore. I saw my console hanging when I entered the command without a password.

If you need a quick ad-hoc solution for common cases with minimum code, then this recursive CTE two-liner will do it:

DECLARE @s VARCHAR(200) = ',1,2,,3,,,4,,,,5,'

;WITH
a AS (SELECT i=-1, j=0 UNION ALL SELECT j, CHARINDEX(',', @s, j + 1) FROM a WHERE j > i),
b AS (SELECT SUBSTRING(@s, i+1, IIF(j>0, j, LEN(@s)+1)-i-1) s FROM a WHERE i >= 0)
SELECT * FROM b

Either use this as a stand-alone statement or just add the above CTEs to any of your queries and you will be able to join the resulting table b with others for use in any further expressions.

edit (by Shnugo)

If you add a counter, you will get a position index together with the List:

DECLARE @s VARCHAR(200) = '1,2333,344,4'

;WITH
a AS (SELECT n=0, i=-1, j=0 UNION ALL SELECT n+1, j, CHARINDEX(',', @s, j+1) FROM a WHERE j > i),
b AS (SELECT n, SUBSTRING(@s, i+1, IIF(j>0, j, LEN(@s)+1)-i-1) s FROM a WHERE i >= 0)
SELECT * FROM b;

The result:

n   s
1   1
2   2333
3   344
4   4

Without knowing your compiler, no one can give you specific, step by step instructions, but the basic procedure is as follows:

1. Specify the path which should be searched in order to find the actual library (usually under Library Search Paths, Library Directories, etc. in the properties page)

2. Under linker options, specify the actual name of the library. In VS, you would write Allegro.lib (or whatever it is), on Linux you usually just write Allegro (prefixes/suffixes are added automatically in most cases). This is usually under "Libraries->Input", just "Libraries", or something similar.

3. Ensure that you have included the headers for the library and make sure that they can be found (similar process to that listed in step #1 and #2). If it is a static library, you should be good; if it's a DLL, you need to copy it in your project.

4. Mash the build button.

Choreographer lets apps to connect themselves to the vsync, and properly time things to improve performance.

Android view animations internally uses Choreographer for the same purpose: to properly time the animations and possibly improve performance.

Since Choreographer is told about every vsync events, it can tell if one of the Runnables passed along by the Choreographer.post* apis doesn't finish in one frame's time, causing frames to be skipped.

In my understanding Choreographer can only detect the frame skipping. It has no way of telling why this happens.

The message "The application may be doing too much work on its main thread." could be misleading.

I was struggling with the same issue and didn't work for me using this

{{dateObj | date:'ydM'}}

So, I've tried a workaround, not the best solution but it worked:

{{dateObj | date:'d'}}/{{dateObj | date:'M'}}/{{dateObj | date:'y'}}

I can always create a custom pipe.

Please open your Visual Studio as administrator:

A very simple and elegant solution to this is provided by W3C. Simply use the margin:0 auto declaration as follows:

.top_image img { margin:0 auto; }

Microsoft is moving away from software and database diagramming using Visio and instead transitioning into Visual Studio. See the "Modeling" Projects.

ScreenShot

There are a few different options on how to do this. The most basic is to use varargin, and then use nargin, size etc. to determine whether the optional arguments have been passed to the function.

% Function that takes two arguments, X & Y, followed by a variable 
% number of additional arguments
function varlist(X,Y,varargin)
   fprintf('Total number of inputs = %d\n',nargin);

   nVarargs = length(varargin);
   fprintf('Inputs in varargin(%d):\n',nVarargs)
   for k = 1:nVarargs
      fprintf('   %d\n', varargin{k})
   end

A little more elegant looking solution is to use the inputParser class to define all the arguments expected by your function, both required and optional. inputParser also lets you perform type checking on all arguments.

This is a very old thread, but I have found a pure CSS solution to this using some creative nesting. I wasn't a fan of the jQuery method at all...

Such type of code will also return you the same error this is because of the intents as the return statement should be for else not for if statement.

above code can be changed to

This may solve such issues

There is definitively no way to do this with standard formulas. However, a crazy sort of answer can be found here. It still avoids VBA, and it will allow you to get your result dynamically.

1. First, make the formula that will generate your formula, but don't add the = at the beginning!

2. Let us pretend that you have created this formula in cell B2 of Sheet1, and you would like the formula to be evaluated in column c.

3. Now, go to the Formulas tab, and choose "Define Name". Give it the name myResult (or whatever you choose), and under Refers To, write =evaluate(Sheet1!$B2) (note the $)

4. Finally, go to C2, and write =myResult. Drag down, and... voila!

I think following command may help you!

mvn -U clean install

Same problem as above, but vastly different root. For me, it was that I was hitting an endpoint with an https rewrite rule. Hitting it on http caused the error, worked as expected with https.

By default CM10 only allows root access from Apps not ADB. Go to Settings -> Developer options -> Root access, and change option to "Apps and ADB".

The following worked for me:

import sys, glob
sys.path.append('/home/marc/python/importtest/modus')
fl = glob.glob('modus/*.py')
modulist = []
adapters=[]
for i in range(len(fl)):
    fl[i] = fl[i].split('/')[1]
    fl[i] = fl[i][0:(len(fl[i])-3)]
    modulist.append(getattr(__import__(fl[i]),fl[i]))
    adapters.append(modulist[i]())

It loads modules from the folder 'modus'. The modules have a single class with the same name as the module name. E.g. the file modus/modu1.py contains:

class modu1():
    def __init__(self):
        self.x=1
        print self.x

The result is a list of dynamically loaded classes "adapters".

You can either use the eval function as in some other answers. (Don't forget the extra braces.) You will know why when you dig deeper), or simply use the jQuery function parseJSON:

var response = '{"result":true , "count":1}'; 
var parsedJSON = $.parseJSON(response);

OR

You can use this below code.

var response = '{"result":true , "count":1}';
var jsonObject = JSON.parse(response);

And you can access the fields using jsonObject.result and jsonObject.count.

Update:

If your output is undefined then you need to follow THIS answer. Maybe your json string has an array format. You need to access the json object properties like this

var response = '[{"result":true , "count":1}]'; // <~ Array with [] tag
var jsonObject = JSON.parse(response);
console.log(jsonObject[0].result); //Output true
console.log(jsonObject[0].count); //Output 1

You are splitting a string on a fairly complex sub string. I'd use regular expressions instead of String.Split. The later is more for tokenizing you text.

For example:

var rx = new System.Text.RegularExpressions.Regex("is Marco and");
var array = rx.Split("My name is Marco and I'm from Italy");

You need to escape the backslash \:

println yourString.replace("\\", "/")

System.out.print("Enter a Value: ");
val = s.nextInt();

This line is placed in last.The whole code is as follows:-

public static void main(String[] args){
    int min, max;

    Scanner s = new Scanner(System.in);
    System.out.print("Enter a Value: ");
    int val = s.nextInt();
    min = max = val;

    while (val != 0) {
        if (val < min) {
            min = val;
        }
        if (val > max) {
            max = val;
        }
        System.out.print("Enter a Value: ");
        val = s.nextInt();

    }
    System.out.println("Min: " + min);
    System.out.println("Max: " + max);
}

In my case I missed to call the constructor of the class I inherited from.

Before:

@Component({ ... })
export class ComponentA extends ComponentParent {
  // ...
}

After:

@Component({ ... })
export class ComponentA extends ComponentParent {
  constructor(protected route: ActivatedRoute, protected store$: Store<AppState>) {
    super(route, store$);
  }
  // ...
}

DateTime.Parse() will try figure out the format of the given date, and it usually does a good job. If you can guarantee dates will always be in a given format then you can use ParseExact():

string s = "2011-03-21 13:26";

DateTime dt = 
    DateTime.ParseExact(s, "yyyy-MM-dd HH:mm", CultureInfo.InvariantCulture);

(But note that it is usually safer to use one of the TryParse methods in case a date is not in the expected format)

Make sure to check Custom Date and Time Format Strings when constructing format string, especially pay attention to number of letters and case (i.e. "MM" and "mm" mean very different things).

Another useful resource for C# format strings is String Formatting in C#

I ran into this same issue recently, posted the my solution also here: Preventing element from displaying on top of footer when using position:fixed

You can achieve a solution leveraging the position property of the element with jQuery, switching between the default value (static for divs), fixed and absolute. You will also need a container element for your fixed element. Finally, in order to prevent the fixed element to go over the footer, this container element can't be the parent of the footer.

The javascript part involves calculating the distance in pixels between your fixed element and the top of the document, and comparing it with the current vertical position of the scrollbar relatively to the window object (i.e. the number of pixels above that are hidden from the visible area of the page) every time the user scrolls the page. When, on scrolling down, the fixed element is about to disappear above, we change its position to fixed and stick on top of the page.

This causes the fixed element to go over the footer when we scroll to the bottom, especially if the browser window is small. Therefore, we will calculate the distance in pixels of the footer from the top of the document and compare it with the height of the fixed element plus the vertical position of the scrollbar: when the fixed element is about to go over the footer, we will change its position to absolute and stick at the bottom, just over the footer.

Here's a generic example.

The HTML structure:

<div id="content">
    <div id="leftcolumn">
        <div class="fixed-element">
            This is fixed 
        </div>
    </div>
    <div id="rightcolumn">Main content here</div>
    <div id="footer"> The footer </div>
</div>  

The CSS:

#leftcolumn {
    position: relative;
}
.fixed-element {
    width: 180px;
}
.fixed-element.fixed {
    position: fixed;
    top: 20px;
}
.fixed-element.bottom {
    position: absolute;
    bottom: 356px; /* Height of the footer element, plus some extra pixels if needed */
}

The JS:

// Position of fixed element from top of the document
var fixedElementOffset = $('.fixed-element').offset().top;
// Position of footer element from top of the document.
// You can add extra distance from the bottom if needed,
// must match with the bottom property in CSS
var footerOffset = $('#footer').offset().top - 36;

var fixedElementHeight = $('.fixed-element').height(); 

// Check every time the user scrolls
$(window).scroll(function (event) {

    // Y position of the vertical scrollbar
    var y = $(this).scrollTop();

    if ( y >= fixedElementOffset && ( y + fixedElementHeight ) < footerOffset ) {
        $('.fixed-element').addClass('fixed');
        $('.fixed-element').removeClass('bottom');          
    }
    else if ( y >= fixedElementOffset && ( y + fixedElementHeight ) >= footerOffset ) {
        $('.fixed-element').removeClass('fixed');           
        $('.fixed-element').addClass('bottom');
    }
    else {
        $('.fixed-element').removeClass('fixed bottom');
    }

 });

You can also "WAITFOR" a "TIME":

    RAISERROR('Im about to wait for a certain time...', 0, 1) WITH NOWAIT
    WAITFOR TIME '16:43:30.000'
    RAISERROR('I waited!', 0, 1) WITH NOWAIT

It's much more easier to add only the event for mousedown:

private void MyDataGridView_MouseDown(object sender, MouseEventArgs e)
{
    if (e.Button == MouseButtons.Right)
    {
        var hti = MyDataGridView.HitTest(e.X, e.Y);
        MyDataGridView.Rows[hti.RowIndex].Selected = true;
        MyDataGridView.Rows.RemoveAt(rowToDelete);
        MyDataGridView.ClearSelection();
    }
}

This is easier. Of cource you have to init your mousedown-event as already mentioned with:

this.MyDataGridView.MouseDown += new System.Windows.Forms.MouseEventHandler(this.MyDataGridView_MouseDown);

in your constructor.

One idea:

try {
    int i = Integer.parseInt(myString);
    if (i < 0) {
        // Error, negative input
    }
} catch (NumberFormatException e) {
    // Error, not a number.
}

There is also, in commons-lang library the CharUtils class that provides the methods isAsciiNumeric() to check that a character is a number, and isAsciiAlpha() to check that the character is a letter...

The following works fine for me in Excel 2007. It is simple, and performs a full copy (retains all formatting, etc.):

Sheets("Sheet1").Columns(1).Copy Destination:=Sheets("Sheet2").Columns(2)

"Columns" returns a Range object, and so this is utilizing the "Range.Copy" method. "Destination" is an option to this method - if not provided the default is to copy to the paste buffer. But when provided, it is an easy way to copy.

As when manually copying items in Excel, the size and geometry of the destination must support the range being copied.

Create Relative layout and inside that layout create your button with this line

android:layout_alignParentBottom="true"

From something that is ContainerAware (like a controller):

$request = $this->container->get('request');
$routeName = $request->get('_route');

The code on Scene delegate in Swift UI

Content view background-color

window.rootViewController?.view.backgroundColor = .lightGray

Both answers given are correct, but I do mine a little different. You might want to consider a couple things...

Start the batch with:

SetLocal

and end it with

EndLocal

This will keep all your 'SETs" to be only valid during the current session, and will not leave vars left around named like "FileName1" or any other variables you set during the run, that could interfere with the next run of the batch file. So, you can do something like:

IF "%1"=="" SET FileName1=c:\file1.txt

The other trick is if you only provide 1, or 2 parameters, use the SHIFT command to move them, so the one you are looking for is ALWAYS at %1...

For example, process the first parameter, shift them, and then do it again. This way, you are not hard-coding %1, %2, %3, etc...

The Windows batch processor is much more powerful than people give it credit for.. I've done some crazy stuff with it, including calculating yesterday's date, even across month and year boundaries including Leap Year, and localization, etc.

If you really want to get creative, you can call functions in the batch processor... But that's really for a different discussion... :)

Oh, and don't name your batch files .bat either.. They are .cmd's now.. heh..

Hope this helps.

The element is supported by all browsers and defines an embedded object within an HTML document.

Bottom line: OBJECT is Good, EMBED is Old. Beside's IE's PARAM tags, any content between OBJECT tags will get rendered if the browser doesn't support OBJECT's referred plugin, and apparently, the content gets http requested regardless if it gets rendered or not. Reference

Assuming you want an icon on the right (or left) then this should work best:

.show-hide-button::after {
    content:"";
    background-repeat: no-repeat;
    background-size: contain;
    display: inline-block;
    background-size: 1em;
    width: 1em;
    height: 1em;
    background-position: 0 2px;
    margin-left: .5em;
}
.show-hide-button.shown::after {
    background-image: url(img/eye.svg);
}

You could also do background-size: contain;, but that should be mostly the same. the background-position will depened on your image.

Then you can easily do an alternative state on hover:

.show-hide-button.shown:hover::after {
    background-image: url(img/eye-no.svg);
}

<img id="uxcMyImageId" src"myImage" width="100" height="100" />

specifying width and height in the image tag is a good practice..this way when the page loads there is space allocated for the image and the layout does not suffer any jerks even if the image takes a long time to load.

I would prefer it without enumerate and instead use "range" like this:

for item in range(0, len(alist)):
   if 123 in alist[item]:
      alist[item] = 2014

For those who are new to python it might be more readable and a little smarter to recap.

Assuming you have some level of control over the protocol, I'm a big fan of sending heartbeats to verify that a connection is active. It's proven to be the most fail proof method and will often give you the quickest notification when a connection has been broken.

TCP keepalives will work, but what if the remote host is suddenly powered off? TCP can take a long time to timeout. On the other hand, if you have logic in your app that expects a heartbeat reply every x seconds, the first time you don't get them you know the connection no longer works, either by a network or a server issue on the remote side.

See Do I need to heartbeat to keep a TCP connection open? for more discussion.

I wouldn't use a List in the first places as an EnumSet is more approriate but you can do

List<Something> somethingList = Arrays.asList(Something.values());

or

List<Something> somethingList =
                 new ArrayList<Something>(EnumSet.allOf(Something.class));

You can try http://www.datejs.com/

 $('#idInput').val( Date.parse("Jun 18, 2017 7:00:00 PM").toString('yyyy-MM-dd'));

You'll want to use a udf as below

from pyspark.sql.types import IntegerType
from pyspark.sql.functions import udf

def func(fruit1, fruit2):
    if fruit1 == None or fruit2 == None:
        return 3
    if fruit1 == fruit2:
        return 1
    return 0

func_udf = udf(func, IntegerType())
df = df.withColumn('new_column',func_udf(df['fruit1'], df['fruit2']))

With introduction of ContraintLayout, it's possible to implement with Guidelines:

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.example.eugene.test1.MainActivity">

    <TextView
        android:id="@+id/textView"
        android:layout_width="0dp"
        android:layout_height="0dp"
        android:background="#AAA"
        android:text="TextView"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintBottom_toTopOf="@+id/guideline" />

    <android.support.constraint.Guideline
        android:id="@+id/guideline"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        app:layout_constraintGuide_percent="0.5" />

</android.support.constraint.ConstraintLayout>

Assert does throw an AssertionError if you run your app with assertions turned on.

int a = 42;
assert a >= 0 && d <= 10;

If you run this with, say: java -ea -jar peiska.jar

It shall throw an java.lang.AssertionError

Also as a minor enhancement.

The main reason for the try/catch block is that e1 could be null for the initial movement. in addition to the try/catch, include a test for null and return. similar to the following

if (e1 == null || e2 == null) return false;
try {
...
} catch (Exception e) {}
return false;

You need to pass your context to your fyl class..
One solution is make a constructor like this for your fyl class:

public class fyl {
 Context mContext;
 public fyl(Context mContext) {
       this.mContext = mContext;
 }

 public Location getLocation() {
       --
       locationManager = (LocationManager)mContext.getSystemService(context);

       --
 }
}

So in your activity class create the object of fyl in onCreate function like this:

package com.atClass.lmt;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
import android.location.Location;

public class lmt extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        fyl lfyl = new fyl(this); //Here the context is passing 

        Location location = lfyl.getLocation();
        String latLongString = lfyl.updateWithNewLocation(location);

        TextView myLocationText = (TextView)findViewById(R.id.myLocationText);
        myLocationText.setText("Your current position is:\n" + latLongString);
    }
}

Use the below code in android.support.v4

FragmentTransaction ft1 = getFragmentManager().beginTransaction();
WebViewFragment w1 = new WebViewFragment();
w1.init(linkData.getLink());
ft1.addToBackStack(linkData.getName());
ft1.replace(R.id.listFragment, w1);
ft1.commit();

Use its value directly:

In [79]: df[df.c > 0.5][['b', 'e']].values
Out[79]: 
array([[ 0.98836259,  0.82403141],
       [ 0.337358  ,  0.02054435],
       [ 0.29271728,  0.37813099],
       [ 0.70033513,  0.69919695]])

The simplest way I found is by making the element font-size: 0px, then overwrite it with any font size when creating :after pseudo. Example below:

.pvw-title { 
    font-size:0px;
}

.pvw-title:after {
        content: "Hello";
        font-size:15px !important;
}

If you are searching by the fieldname1 value, try this:

var r = exitDictionary
   .Select(i => i.Value).Cast<Dictionary<string, object>>()
   .Where(d => d.ContainsKey("fieldname1"))
   .Select(d => d["fieldname1"]).Cast<List<Dictionary<string, string>>>()
   .SelectMany(d1 => 
       d1
        .Where(d => d.ContainsKey("valueTitle"))
        .Select(d => d["valueTitle"])
        .Where(v => v != null)).ToList();

If you are looking by the type of the value in the subDictionary (Dictionary<string, object> explicitly), you may do this:

var r = exitDictionary
   .Select(i => i.Value).Cast<Dictionary<string, object>>()
   .SelectMany(d=>d.Values)
   .OfType<List<Dictionary<string, string>>>()
   .SelectMany(d1 => 
       d1
        .Where(d => d.ContainsKey("valueTitle"))
        .Select(d => d["valueTitle"])
        .Where(v => v != null)).ToList();

Both alternatives will return:

title1
title2
title3
title1
title2
title3

Blundell's first answer didn't work for me. However it showed me the right way. I have done the same thing like this:

> for i in `git ls-files -i --exclude-from=.gitignore`; do git rm --cached $i; done
> git commit -m 'Removed all files that are in the .gitignore'
> git push origin master

I advise you to check the files to be deleted first by running the below statement:

git ls-files -i --exclude-from=.gitignore

I was using a default .gitignore file for visual studio and I noticed that it was removing all log and bin folders in the project which was not my intended action.

To make the answer more re-usable for things other than just the datepicker change function you can create a prototype to handle this for you.

// safety check to see if the prototype name is already defined
Function.prototype.method = function (name, func) {
    if (!this.prototype[name]) {
        this.prototype[name] = func;
        return this;
    }
};
Date.method('inPast', function () {
    return this < new Date($.now());// the $.now() requires jQuery
});

// including this prototype as using in example
Date.method('addDays', function (days) {
    var date = new Date(this);
    date.setDate(date.getDate() + (days));    
    return date;
});

If you dont like the safety check you can use the conventional way to define prototypes:

Date.prototype.inPast = function(){
    return this < new Date($.now());// the $.now() requires jQuery
}

Example Usage

var dt = new Date($.now());
var yesterday = dt.addDays(-1);
var tomorrow = dt.addDays(1);
console.log('Yesterday: ' + yesterday.inPast());
console.log('Tomorrow: ' + tomorrow.inPast());

  try {
        $result=DB::table('users')->whereExists(function ($Query){
            $Query->where('id','<','14162756');
            $Query->whereBetween('password',[14162756,48384486]);
            $Query->whereIn('id',[3,8,12]);
        });
    }catch (\Exception $error){
        Log::error($error);
        DB::rollBack(1);
        return redirect()->route('bye');
    }

Escaping works.

#!/bin/bash

Quoting the strings also produces the same output.

You could apply position: relative; to the div and then position: absolute; top: 0; to a paragraph or span inside of it containing the text.

In my case it was an idle timeout, that caused the connection to be dropped on the server. The connection was kept open, but not used for a long period of time. Then a client restart works, while I believe a reconnect will work as well.

A not bad solution is to have a daemon/service to ping the connection from time to time.

You can use the Object.values() method if you dont want to use the Object.keys().

As opposed to the Object.keys() method that returns an array of a given object's own enumerable properties, so for instance:

const object1 = {
 a: 'somestring',
 b: 42,
 c: false
};

console.log(Object.keys(object1));

Would print out the following array:

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

The Object.values() method returns an array of a given object's own enumerable property values.

So if you have the same object but use values instead,

const object1 = {
 a: 'somestring',
 b: 42,
 c: false
};

console.log(Object.values(object1));

You would get the following array:

[ 'somestring', 42, false ]

So if you wanted to access the object1.b, but using an index instead you could use:

Object.values(object1)[1] === 42

You can read more about this method here.

First, checkout parent branch.Then type

git fetch --all --prune 
git checkout <your branch>

Hope it helps!.

I'd say export your server config in IIS manager:

1. In IIS manager, click the Server node
2. Go to Shared Configuration under "Management"
3. Click “Export Configuration”. (You can use a password if you are sending them across the internet, if you are just gonna move them via a USB key then don't sweat it.)

4. Move these files to your new server

   administration.config
   applicationHost.config
   configEncKey.key 
   

5. On the new server, go back to the “Shared Configuration” section and check “Enable shared configuration.” Enter the location in physical path to these files and apply them.

6. It should prompt for the encryption password(if you set it) and reset IIS.

BAM! Go have a beer!

Yes they do.

You shouldn't really be overriding the constructor anyway. You should have a newInstance() static method defined and pass any parameters via arguments (bundle)

For example:

public static final MyFragment newInstance(int title, String message) {
    MyFragment f = new MyFragment();
    Bundle bdl = new Bundle(2);
    bdl.putInt(EXTRA_TITLE, title);
    bdl.putString(EXTRA_MESSAGE, message);
    f.setArguments(bdl);
    return f;
}

And of course grabbing the args this way:

@Override
public void onCreate(Bundle savedInstanceState) {
    title = getArguments().getInt(EXTRA_TITLE);
    message = getArguments().getString(EXTRA_MESSAGE);

    //...
    //etc
    //...
}

Then you would instantiate from your fragment manager like so:

@Override
public void onCreate(Bundle savedInstanceState) {
    if (savedInstanceState == null){
        getSupportFragmentManager()
            .beginTransaction()
            .replace(R.id.content, MyFragment.newInstance(
                R.string.alert_title,
                "Oh no, an error occurred!")
            )
            .commit();
    }
}

This way if detached and re-attached the object state can be stored through the arguments. Much like bundles attached to Intents.

Reason - Extra reading

I thought I would explain why for people wondering why.

If you check: https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/app/Fragment.java

You will see the instantiate(..) method in the Fragment class calls the newInstance method:

public static Fragment instantiate(Context context, String fname, @Nullable Bundle args) {
    try {
        Class<?> clazz = sClassMap.get(fname);
        if (clazz == null) {
            // Class not found in the cache, see if it's real, and try to add it
            clazz = context.getClassLoader().loadClass(fname);
            if (!Fragment.class.isAssignableFrom(clazz)) {
                throw new InstantiationException("Trying to instantiate a class " + fname
                        + " that is not a Fragment", new ClassCastException());
            }

http://docs.oracle.com/javase/6/docs/api/java/lang/Class.html#newInstance() Explains why, upon instantiation it checks that the accessor is public and that that class loader allows access to it.

It's a pretty nasty method all in all, but it allows the FragmentManger to kill and recreate Fragments with states. (The Android subsystem does similar things with Activities).

Example Class

I get asked a lot about calling newInstance. Do not confuse this with the class method. This whole class example should show the usage.

/**

public class StationInfoAccessibilityFragment extends BaseFragment implements JourneyProviderListener {

    public static final StationInfoAccessibilityFragment newInstance(String crsCode) {
        StationInfoAccessibilityFragment fragment = new StationInfoAccessibilityFragment();

        final Bundle args = new Bundle(1);
        args.putString(EXTRA_CRS_CODE, crsCode);
        fragment.setArguments(args);

        return fragment;
    }

    // Views
    LinearLayout mLinearLayout;

    /**
     * Layout Inflater
     */
    private LayoutInflater mInflater;
    /**
     * Station Crs Code
     */
    private String mCrsCode;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        mCrsCode = getArguments().getString(EXTRA_CRS_CODE);
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        mInflater = inflater;
        return inflater.inflate(R.layout.fragment_station_accessibility, container, false);
    }

    @Override
    public void onViewCreated(View view, Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);
        mLinearLayout = (LinearLayout)view.findViewBy(R.id.station_info_accessibility_linear);
        //Do stuff
    }

    @Override
    public void onResume() {
        super.onResume();
        getActivity().getSupportActionBar().setTitle(R.string.station_info_access_mobility_title);
    }

    // Other methods etc...
}

For python 3 pip install urllib

If you need a background image, you can use CircleAvatar with IconButton. Set the backgroundImage property.

CircleAvatar(
  backgroundImage: NetworkImage(userAvatarUrl),
)

Example with button:

        CircleAvatar(
          backgroundColor: Colors.blue,
          radius: 20,
          child: IconButton(
            padding: EdgeInsets.zero,
            icon: Icon(Icons.add),
            color: Colors.white,
            onPressed: () {},
          ),
        ),

If all the keys are strings and all of them have the underscore prefix, then you can patch up the hash in place with this:

h.keys.each { |k| h[k[1, k.length - 1]] = h[k]; h.delete(k) }

The k[1, k.length - 1] bit grabs all of k except the first character. If you want a copy, then:

new_h = Hash[h.map { |k, v| [k[1, k.length - 1], v] }]

Or

new_h = h.inject({ }) { |x, (k,v)| x[k[1, k.length - 1]] = v; x }

You could also use sub if you don't like the k[] notation for extracting a substring:

h.keys.each { |k| h[k.sub(/\A_/, '')] = h[k]; h.delete(k) }
Hash[h.map { |k, v| [k.sub(/\A_/, ''), v] }]
h.inject({ }) { |x, (k,v)| x[k.sub(/\A_/, '')] = v; x }

And, if only some of the keys have the underscore prefix:

h.keys.each do |k|
  if(k[0,1] == '_')
    h[k[1, k.length - 1]] = h[k]
    h.delete(k)
  end
end

Similar modifications can be done to all the other variants above but these two:

Hash[h.map { |k, v| [k.sub(/\A_/, ''), v] }]
h.inject({ }) { |x, (k,v)| x[k.sub(/\A_/, '')] = v; x }

should be okay with keys that don't have underscore prefixes without extra modifications.

I've just used Excel 2016 to open Access 2003 tables.

1. Open a new worksheet
2. Go to Data tab
3. Click on "From Access" menu item
4. Select the database's .mdb file
5. In the "Data Link Properties" box that opens, switch to the "Provider" tab
6. Select the "Microsoft Jet 4.0 OLE DB Provider"
7. Click on Next
8. Reselect the database's .mdb file (it forgets it when you change Provider)
9. Click OK
10. From the Select Table dialogue that appears, choose the table you want to import.

Well, the problem is that Files.newBufferedReader(Path path) is implemented like this :

public static BufferedReader newBufferedReader(Path path) throws IOException {
    return newBufferedReader(path, StandardCharsets.UTF_8);
}

so basically there is no point in specifying UTF-8 unless you want to be descriptive in your code. If you want to try a "broader" charset you could try with StandardCharsets.UTF_16, but you can't be 100% sure to get every possible character anyway.

This is what I'm using at the moment:

import os, shutil
path = "/volume1/Users/Transfer/"
moveto = "/volume1/Users/Drive_Transfer/"
files = os.listdir(path)
files.sort()
for f in files:
    src = path+f
    dst = moveto+f
    shutil.move(src,dst)

Now fully functional. Hope this helps you.

Edit:

I've turned this into a function, that accepts a source and destination directory, making the destination folder if it doesn't exist, and moves the files. Also allows for filtering of the src files, for example if you only want to move images, then you use the pattern '*.jpg', by default, it moves everything in the directory

import os, shutil, pathlib, fnmatch

def move_dir(src: str, dst: str, pattern: str = '*'):
    if not os.path.isdir(dst):
        pathlib.Path(dst).mkdir(parents=True, exist_ok=True)
    for f in fnmatch.filter(os.listdir(src), pattern):
        shutil.move(os.path.join(src, f), os.path.join(dst, f))

Dont use a foreach then. Use a 'for loop'. Your code is a bit messed up but you could do something like...

for (Int32 i = 0; i < dt_pattern.Rows.Count; i++)
{
    double yATmax = ToDouble(dt_pattern.Rows[i+1]["Ampl"].ToString()) + AT;
}

Note you would have to take into account during the last row there will be no 'i+1' so you will have to use an if statement to catch that.

One thing I want to add. Sometimes, there can be precision loss. You may want to add some epsilon value first before converting. Not sure why that works... but it work.

int someint = (somedouble+epsilon);

Apache PDFBox also works great for me.

Usage with the command line tool:

javar -jar pdfbox-app-2.0.19.jar PDFToImage -quality 1.0  -dpi 150 -prefix out_dir/page -format png

You can do it as simple as this using swift 2:

let alertController = UIAlertController(title: "iOScreator", message:
        "Hello, world!", preferredStyle: UIAlertControllerStyle.Alert)
alertController.addAction(UIAlertAction(title: "Dismiss", style: UIAlertActionStyle.Destructive,handler: { action in
        self.pressed()
}))

func pressed()
{
    print("you pressed")
}

    **or**


let alertController = UIAlertController(title: "iOScreator", message:
        "Hello, world!", preferredStyle: UIAlertControllerStyle.Alert)
alertController.addAction(UIAlertAction(title: "Dismiss", style: UIAlertActionStyle.Destructive,handler: { action in
      print("pressed")
 }))

All the answers above are correct i am just showing another way that can be done.

There's a change_column method, just execute it in your migration with datetime as a new type.

change_column(:my_table, :my_column, :my_new_type)

<gradient android:startColor="#ffdd00"
    android:endColor="@color/colorPrimary"
    android:centerColor="#ffff" />

<corners android:radius="33dp"/>

<padding
    android:bottom="7dp"
    android:left="7dp"
    android:right="7dp"
    android:top="7dp"
    />

The following code will reduce the problem to check the protocol. The $_SERVER['APP_URL'] will display the domain name with the protocol

$_SERVER['APP_URL'] will return protocol://domain ( eg:-http://localhost)

$_SERVER['REQUEST_URI'] for remaining parts of the url such as /directory/subdirectory/something/else

 $url = $_SERVER['APP_URL'].$_SERVER['REQUEST_URI'];

The output would be like this

http://localhost/directory/subdirectory/something/else

With Subversion 1.5, it becomes possible to check out (all) the files of a directory without checking out any subdirectories (the various --depth flags). Not quite what you asked for, but a form of "less than all."

Sorry, but it might even be more complicated, involving pbkdf2, or even a variation of it. Listen to the WWDC 2010 session #209, which mainly talks about the security measures in iOS 4, but also mentions briefly the separate encryption of backups and how they're related.

You can be pretty sure that without knowing the password, there's no way you can decrypt it, even by brute force.

Let's just assume you want to try to enable people who KNOW the password to get to the data of their backups.

I fear there's no way around looking at the actual code in iTunes in order to figure out which algos are employed.

Back in the Newton days, I had to decrypt data from a program and was able to call its decryption function directly (knowing the password, of course) without the need to even undersand its algorithm. It's not that easy anymore, unfortunately.

I'm sure there are skilled people around who could reverse engineer that iTunes code - you just have to get them interested.

In theory, Apple's algos should be designed in a way that makes the data still safe (i.e. practically unbreakable by brute force methods) to any attacker knowing the exact encryption method. And in WWDC session 209 they went pretty deep into details about what they do to accomplish this. Maybe you can actually get answers directly from Apple's security team if you tell them your good intentions. After all, even they should know that security by obfuscation is not really efficient. Try their security mailing list. Even if they do not repond, maybe someone else silently on the list will respond with some help.

Good luck!

The linked list holds operations on the shared data structure.

For example, if I have a stack, it will be manipulated with pushes and pops. The linked list would be a set of pushes and pops on the pseudo-shared stack. Each thread sharing that stack will actually have a local copy, and to get to the current shared state, it'll walk the linked list of operations, and apply each operation in order to its local copy of the stack. When it reaches the end of the linked list, its local copy holds the current state (though, of course, it's subject to becoming stale at any time).

In the traditional model, you'd have some sort of locks around each push and pop. Each thread would wait to obtain a lock, then do a push or pop, then release the lock.

In this model, each thread has a local snapshot of the stack, which it keeps synchronized with other threads' view of the stack by applying the operations in the linked list. When it wants to manipulate the stack, it doesn't try to manipulate it directly at all. Instead, it simply adds its push or pop operation to the linked list, so all the other threads can/will see that operation and they can all stay in sync. Then, of course, it applies the operations in the linked list, and when (for example) there's a pop it checks which thread asked for the pop. It uses the popped item if and only if it's the thread that requested this particular pop.

var result = priceLog.GroupBy(s => s.LogDateTime.ToString("MMM yyyy")).Select(grp => new PriceLog() { LogDateTime = Convert.ToDateTime(grp.Key), Price = (int)grp.Average(p => p.Price) }).ToList();

I have converted it to int because my Price field was int and Average method return double .I hope this will help

I'm surprised no one has mentioned using regular expressions via re.sub():

import re
print re.sub(r'([\"])',    r'\\\1', 'it\'s "this"')  # it's \"this\"
print re.sub(r"([\'])",    r'\\\1', 'it\'s "this"')  # it\'s "this"
print re.sub(r'([\" \'])', r'\\\1', 'it\'s "this"')  # it\'s\ \"this\"

Important things to note:

• In the search pattern, include \ as well as the character(s) you're looking for. You're going to be using \ to escape your characters, so you need to escape that as well.
• Put parentheses around the search pattern, e.g. ([\"]), so that the substitution pattern can use the found character when it adds \ in front of it. (That's what \1 does: uses the value of the first parenthesized group.)
• The r in front of r'([\"])' means it's a raw string. Raw strings use different rules for escaping backslashes. To write ([\"]) as a plain string, you'd need to double all the backslashes and write '([\\"])'. Raw strings are friendlier when you're writing regular expressions.
• In the substitution pattern, you need to escape \ to distinguish it from a backslash that precedes a substitution group, e.g. \1, hence r'\\\1'. To write that as a plain string, you'd need '\\\\\\1' — and nobody wants that.

This answer has been very beautifully explained in book "Microservices Interview Questions, For Java Developers (Spring Boot, Spring Cloud, Cloud Native Applications) by Munish Chandel, Version 1.30, 25.03.2018.

The following content has been taken from this book, and total credit for this answer goes to the Author of the book i.e. Munish Chandel

application.yml

application.yml/application.properties file is specific to Spring Boot applications. Unless you change the location of external properties of an application, spring boot will always load application.yml from the following location:

/src/main/resources/application.yml

You can store all the external properties for your application in this file. Common properties that are available in any Spring Boot project can be found at: https://docs.spring.io/spring-boot/docs/current/reference/html/common-application-properties.html You can customize these properties as per your application needs. Sample file is shown below:

spring:
    application:
        name: foobar
    datasource:
        driverClassName: com.mysql.jdbc.Driver
        url: jdbc:mysql://localhost/test
server:
    port: 9000

bootstrap.yml

bootstrap.yml on the other hand is specific to spring-cloud-config and is loaded before the application.yml

bootstrap.yml is only needed if you are using Spring Cloud and your microservice configuration is stored on a remote Spring Cloud Config Server.

Important points about bootstrap.yml

1. When used with Spring Cloud Config server, you shall specify the application-name and config git location using below properties.

spring.application.name: "application-name"
spring.cloud.config.server.git.uri: "git-uri-config"

2. When used with microservices (other than cloud config server), we need to specify the application name and location of config server using below properties

spring.application.name: 
spring.cloud.config.uri: 

3. This properties file can contain other configuration relevant to Spring Cloud environment for e.g. eureka server location, encryption/decryption related properties.

Upon startup, Spring Cloud makes an HTTP(S) call to the Spring Cloud Config Server with the name of the application and retrieves back that application’s configuration.

application.yml contains the default configuration for the microservice and any configuration retrieved (from cloud config server) during the bootstrap process will override configuration defined in application.yml

tl;dr: (try it here)

If you have the following HTML:

<div id="menu" style="display: none;">
   <!-- menu stuff in here -->
   <ul><li>Menu item</li></ul>
</div>

<div class="parent">Hover over me to show the menu here</div>

then you can use the following JavaScript code:

$(".parent").mouseover(function() {
    // .position() uses position relative to the offset parent, 
    var pos = $(this).position();

    // .outerWidth() takes into account border and padding.
    var width = $(this).outerWidth();

    //show the menu directly over the placeholder
    $("#menu").css({
        position: "absolute",
        top: pos.top + "px",
        left: (pos.left + width) + "px"
    }).show();
});

But it doesn't work!

This will work as long as the menu and the placeholder have the same offset parent. If they don't, and you don't have nested CSS rules that care where in the DOM the #menu element is, use:

$(this).append($("#menu"));

just before the line that positions the #menu element.

But it still doesn't work!

You might have some weird layout that doesn't work with this approach. In that case, just use jQuery.ui's position plugin (as mentioned in an answer below), which handles every conceivable eventuality. Note that you'll have to show() the menu element before calling position({...}); the plugin can't position hidden elements.

Update notes 3 years later in 2012:

(The original solution is archived here for posterity)

So, it turns out that the original method I had here was far from ideal. In particular, it would fail if:

• the menu's offset parent is not the placeholder's offset parent
• the placeholder has a border/padding

Luckily, jQuery introduced methods (position() and outerWidth()) way back in 1.2.6 that make finding the right values in the latter case here a lot easier. For the former case, appending the menu element to the placeholder works (but will break CSS rules based on nesting).

Don't try this, totally un-recommend, don't do this:

import string
s='ABCD'
print(''.join([string.ascii_lowercase[string.ascii_uppercase.index(i)] for i in s]))

Output:

abcd

Since no one wrote it yet you can use swapcase (so uppercase letters will become lowercase, and vice versa) (and this one you should use in cases where i just mentioned (convert upper to lower, lower to upper)):

s='ABCD'
print(s.swapcase())

Output:

abcd

if (window.confirm('Really go to another page?'))
{
    alert('message');
    window.location = '/some/url';
}
else
{
    die();
}

<url-pattern>/*</url-pattern>

The /* on a servlet overrides all other servlets, including all servlets provided by the servletcontainer such as the default servlet and the JSP servlet. Whatever request you fire, it will end up in that servlet. This is thus a bad URL pattern for servlets. Usually, you'd like to use /* on a Filter only. It is able to let the request continue to any of the servlets listening on a more specific URL pattern by calling FilterChain#doFilter().

<url-pattern>/</url-pattern>

The / doesn't override any other servlet. It only replaces the servletcontainer's builtin default servlet for all requests which doesn't match any other registered servlet. This is normally only invoked on static resources (CSS/JS/image/etc) and directory listings. The servletcontainer's builtin default servlet is also capable of dealing with HTTP cache requests, media (audio/video) streaming and file download resumes. Usually, you don't want to override the default servlet as you would otherwise have to take care of all its tasks, which is not exactly trivial (JSF utility library OmniFaces has an open source example). This is thus also a bad URL pattern for servlets. As to why JSP pages doesn't hit this servlet, it's because the servletcontainer's builtin JSP servlet will be invoked, which is already by default mapped on the more specific URL pattern *.jsp.

<url-pattern></url-pattern>

Then there's also the empty string URL pattern . This will be invoked when the context root is requested. This is different from the <welcome-file> approach that it isn't invoked when any subfolder is requested. This is most likely the URL pattern you're actually looking for in case you want a "home page servlet". I only have to admit that I'd intuitively expect the empty string URL pattern and the slash URL pattern / be defined exactly the other way round, so I can understand that a lot of starters got confused on this. But it is what it is.

Front Controller

In case you actually intend to have a front controller servlet, then you'd best map it on a more specific URL pattern like *.html, *.do, /pages/*, /app/*, etc. You can hide away the front controller URL pattern and cover static resources on a common URL pattern like /resources/*, /static/*, etc with help of a servlet filter. See also How to prevent static resources from being handled by front controller servlet which is mapped on /*. Noted should be that Spring MVC has a builtin static resource servlet, so that's why you could map its front controller on / if you configure a common URL pattern for static resources in Spring. See also How to handle static content in Spring MVC?

Use boolean function like below:

//a[(contains(@id, 'xx'))=false]

From the Google Font Directory examples:

@font-face {
  font-family: 'Tangerine';
  font-style: normal;
  font-weight: normal;
  src: local('Tangerine'), url('http://example.com/tangerine.ttf') format('truetype');
}
body {
  font-family: 'Tangerine', serif;
  font-size: 48px;
}

This works cross browser with .ttf, I believe it may work with .otf. (Wikipedia says .otf is mostly backwards compatible with .ttf) If not, you can convert the .otf to .ttf

Here are some good sites:

• Good primer:

You can use the folowing code:

def float_range(initVal, itemCount, step):
    for x in xrange(itemCount):
        yield initVal
        initVal += step

[x for x in float_range(1, 3, 0.1)]

An earlier comment on an answer said it, but it is easy to miss among all the other answers.

When using bash:

echo this file: "$BASH_SOURCE"
echo this dir: "$(dirname "$BASH_SOURCE")"

Bash Reference Manual, 5.2 Bash Variables

Completely relative:

<img src="kitten.png"/>

this is a relative path indeed.

Absolute in all respects:

<img src="http://www.foo.com/images/kitten.png"/>

this is a URL, and it can be seen in some way as an absolute path, but it's not representative for this matter.

The difference between relative and absolute paths is that when using relative paths you take as reference the current working directory while with absolute paths you refer to a certain, well known directory. Relative paths are useful when you make some program that has to use resources from certain folders that can be opened using the working directory as a starting point.

Example of relative paths:

• image.png, which is the equivalent to .\image.png (in Windows) or ./image.png (anywhere else). The . explicitly specifies that you're expressing a path relative to the current working directory, but this is implied whenever the path doesn't begin at a root directory (designated with a slash), so you don't have to use it necessarily (except in certain contexts where a default directory (or a list of directories to search) will be applied unless you explicitly specify some directory).

• ..\images\image2.jpg This way you can access resources from directories one step up the folders tree.  The ..\ means you've exited the current folder, entering the directory that contains both the working and images folders.  Again, use \ in Windows and / anywhere else.

Example of absolute paths:

• D:\documents\something.doc
• E:\music\good_music.mp3

and so on.

In addition to the answer of BalusC, use the following Java RegExp to replace && with and:

Search:  (#\{[^\}]*)(&&)([^\}]*\})
Replace: $1and$3

You have run this regular expression replacement multiple times to find all occurences in case you are using >2 literals in your EL expressions. Mind to replace the leading # by $ if your EL expression syntax differs.

There is an another issue about connection. Some android versions can connect but some cannot. So there is an another solution

in AndroidManifest.xml:

<application ... android:usesCleartextTraffic="true">_x000D_
        ..._x000D_
    </application>

Just add 'android:usesCleartextTraffic="true"'

and problem solved finally.

I highly recommend you to use ViewStubs like this

<FrameLayout
    android:layout_width="fill_parent"
    android:layout_height="0dp"
    android:layout_weight="1" >

    <ListView
        android:id="@android:id/list"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" />

    <ViewStub
        android:id="@android:id/empty"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:layout="@layout/empty" />
</FrameLayout>

See the full example from Cyril Mottier

std::find().

I believe a simple cast can work

int ascii = (int) "A"

public int height(){

    if(this.root== null) return 0;

    int leftDepth = nodeDepth(this.root.left, 1);
    int rightDepth = nodeDepth(this.root.right, 1);

    int height = leftDepth > rightDepth? leftDepth: rightDepth;

    return height;
}


private int nodeDepth(Node node, int startValue){

    int nodeDepth = 0;

    if(node.left == null && node.right == null) return startValue;
    else{
        startValue++;
        if(node.left!= null){
            nodeDepth = nodeDepth(node.left, startValue);
        }

        if(node.right!= null){
            nodeDepth = nodeDepth(node.right, startValue);
        }
    }

    return nodeDepth;
}

to close bootstrap modal you can pass 'hide' as option to modal method as follow

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

Please take a look at working fiddle here

bootstrap also provide events that you can hook into modal functionality, like if you want to fire a event when the modal has finished being hidden from the user you can use hidden.bs.modal event you can read more about modal methods and events here in Documentation

If non of the above method work, give a id to your close button and trigger click on close button.

type sqlplus/"as sysdba" in cmd for connection in cmd prompt

try this:

for (int i = 1; i <= 20; i++) {
    LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
            LinearLayout.LayoutParams.MATCH_PARENT,
            LinearLayout.LayoutParams.WRAP_CONTENT);
    Button btn = new Button(this);
    btn.setId(i);
    final int id_ = btn.getId();
    btn.setText("button " + id_);
    btn.setBackgroundColor(Color.rgb(70, 80, 90));
    linear.addView(btn, params);
    btn1 = ((Button) findViewById(id_));
    btn1.setOnClickListener(new View.OnClickListener() {
        public void onClick(View view) {
            Toast.makeText(view.getContext(),
                    "Button clicked index = " + id_, Toast.LENGTH_SHORT)
                    .show();
        }
    });
}

You can just create your own .white class and add it to the glyphicon element.

.white, .white a {
  color: #fff;
}

<i class="glyphicon glyphicon-home white"></i>

Add the permissions to the app manifest

Add one of the following permissions as a child of the element in your Android manifest. Either the coarse location permission:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.myapp" >
  ...
  <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
  ...
</manifest>

Or the fine location permission:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.myapp" >
  ...
  <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
  ...
</manifest>

The following code sample checks for permission using the Support library before enabling the My Location layer:

if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION)
                == PackageManager.PERMISSION_GRANTED) {
    mMap.setMyLocationEnabled(true);
} else {
    // Show rationale and request permission.
}
The following sample handles the result of the permission request by implementing the ActivityCompat.OnRequestPermissionsResultCallback from the Support library:

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    if (requestCode == MY_LOCATION_REQUEST_CODE) {
      if (permissions.length == 1 &&
          permissions[0] == Manifest.permission.ACCESS_FINE_LOCATION &&
          grantResults[0] == PackageManager.PERMISSION_GRANTED) {
        mMap.setMyLocationEnabled(true);
    } else {
      // Permission was denied. Display an error message.
    }
}

This example provides current location update using GPS provider. Entire Android app code is as follows,

import android.os.Bundle;
import android.app.Activity;
import android.content.Context;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.widget.TextView;

import android.util.Log;

public class MainActivity extends Activity implements LocationListener{
protected LocationManager locationManager;
protected LocationListener locationListener;
protected Context context;
TextView txtLat;
String lat;
String provider;
protected String latitude,longitude; 
protected boolean gps_enabled,network_enabled;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
txtLat = (TextView) findViewById(R.id.textview1);

locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, this);
}
@Override
public void onLocationChanged(Location location) {
txtLat = (TextView) findViewById(R.id.textview1);
txtLat.setText("Latitude:" + location.getLatitude() + ", Longitude:" + location.getLongitude());
}

@Override
public void onProviderDisabled(String provider) {
Log.d("Latitude","disable");
}

@Override
public void onProviderEnabled(String provider) {
Log.d("Latitude","enable");
}

@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
Log.d("Latitude","status");
}
}
