You can use like below

-(void)myMethod
 {

 NSString* htmlStr = @"<some>html</string>";
 NSString* strWithoutFormatting = [self stringByStrippingHTML:htmlStr];

 }

 -(NSString *)stringByStrippingHTML:(NSString*)str
 {
   NSRange r;
   while ((r = [str rangeOfString:@"<[^>]+>" options:NSRegularExpressionSearch]).location     != NSNotFound)
  {
     str = [str stringByReplacingCharactersInRange:r withString:@""];
 }
  return str;
 }

%08x means that every number should be printed at least 8 characters wide with filling all missing digits with zeros, e.g. for '1' output will be 00000001

Before actually answering your question:

Parameters in a URL (e.g. key=listOfUsers/user1) are GET parameters and you shouldn't be using them for POST requests. A quick explanation of the difference between GET and POST can be found here.

In your case, to make use of REST principles, you should probably have:

http://ip:5000/users
http://ip:5000/users/<user_id>

Then, on each URL, you can define the behaviour of different HTTP methods (GET, POST, PUT, DELETE). For example, on /users/<user_id>, you want the following:

GET /users/<user_id> - return the information for <user_id>
POST /users/<user_id> - modify/update the information for <user_id> by providing the data
PUT - I will omit this for now as it is similar enough to `POST` at this level of depth
DELETE /users/<user_id> - delete user with ID <user_id> 

So, in your example, you want do a POST to /users/user_1 with the POST data being "John". Then the XPath expression or whatever other way you want to access your data should be hidden from the user and not tightly couple to the URL. This way, if you decide to change the way you store and access data, instead of all your URL's changing, you will simply have to change the code on the server-side.

Now, the answer to your question: Below is a basic semi-pseudocode of how you can achieve what I mentioned above:

from flask import Flask
from flask import request

app = Flask(__name__)

@app.route('/users/<user_id>', methods = ['GET', 'POST', 'DELETE'])
def user(user_id):
    if request.method == 'GET':
        """return the information for <user_id>"""
        .
        .
        .
    if request.method == 'POST':
        """modify/update the information for <user_id>"""
        # you can use <user_id>, which is a str but could
        # changed to be int or whatever you want, along
        # with your lxml knowledge to make the required
        # changes
        data = request.form # a multidict containing POST data
        .
        .
        .
    if request.method == 'DELETE':
        """delete user with ID <user_id>"""
        .
        .
        .
    else:
        # POST Error 405 Method Not Allowed
        .
        .
        .

There are a lot of other things to consider like the POST request content-type but I think what I've said so far should be a reasonable starting point. I know I haven't directly answered the exact question you were asking but I hope this helps you. I will make some edits/additions later as well.

Thanks and I hope this is helpful. Please do let me know if I have gotten something wrong.

A Unix timestamp is simply the number of seconds since January the first 1970, so to add 24 hours to a Unix timestamp we just add the number of seconds in 24 hours. (24 * 60 *60)

time() + 24*60*60;

Make it Generic Swift 4

struct Matrix<T> {
    let rows: Int, columns: Int
    var grid: [T]
    init(rows: Int, columns: Int,defaultValue: T) {
        self.rows = rows
        self.columns = columns
        grid = Array(repeating: defaultValue, count: rows * columns) as! [T]
    }
    func indexIsValid(row: Int, column: Int) -> Bool {
        return row >= 0 && row < rows && column >= 0 && column < columns
    }
    subscript(row: Int, column: Int) -> T {
        get {
            assert(indexIsValid(row: row, column: column), "Index out of range")
            return grid[(row * columns) + column]
        }
        set {
            assert(indexIsValid(row: row, column: column), "Index out of range")
            grid[(row * columns) + column] = newValue
        }
    }
}


var matrix:Matrix<Bool> = Matrix(rows: 1000, columns: 1000,defaultValue:false)

matrix[0,10] = true


print(matrix[0,10])

Hashing algorithms are usually cryptographic in nature, but the principal difference is that encryption is reversible through decryption, and hashing is not.

An encryption function typically takes input and produces encrypted output that is the same, or slightly larger size.

A hashing function takes input and produces a typically smaller output, typically of a fixed size as well.

While it isn't possible to take a hashed result and "dehash" it to get back the original input, you can typically brute-force your way to something that produces the same hash.

In other words, if a authentication scheme takes a password, hashes it, and compares it to a hashed version of the requires password, it might not be required that you actually know the original password, only its hash, and you can brute-force your way to something that will match, even if it's a different password.

Hashing functions are typically created to minimize the chance of collisions and make it hard to just calculate something that will produce the same hash as something else.

You could use the @Consumes annotation to get the full body:

import javax.ws.rs.Consumes;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.core.MediaType;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerConfigurationException;
import javax.xml.transform.TransformerException;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamResult;
import org.w3c.dom.Document;

@Path("doc")
public class BodyResource
{
  @POST
  @Consumes(MediaType.APPLICATION_XML)
  public void post(Document doc) throws TransformerConfigurationException, TransformerException
  {
    Transformer tf = TransformerFactory.newInstance().newTransformer();
    tf.transform(new DOMSource(doc), new StreamResult(System.out));
  }
}

Note: Don't forget the "Content-Type: application/xml" header by the request.

Found a workaround solution. Say that you want to scroll to an div, Element here for example, and you want to have a spacing of 20px above it. Set the ref to a created div above it:

<div ref={yourRef} style={{position: 'relative', bottom: 20}}/> <Element />

Doing so will create this spacing that you want.

If you have a header, create an empty div as well behind the header and assign to it a height equal to the height of the header and reference it.

Unless you have sudo permissions to change it or its in your own usergroup/account you will not be able to get into it.

Check out man chmod in the terminal for more information about changing permissions of a directory.

Here's what I did to solve this:

• I removed workspace/.metadata
• run eclipse as an administrator.

You can't, Doctrine 2 doesn't allow for raw queries. It may seem like you can but if you try something like this:

$sql = "SELECT DATE_FORMAT(whatever.createdAt, '%Y-%m-%d') FORM whatever...";
$em = $this->getDoctrine()->getManager();
$em->getConnection()->exec($sql);

Doctrine will spit an error saying that DATE_FORMAT is an unknown function.

But my database (mysql) does know that function, so basically what is hapening is Doctrine is parsing that query behind the scenes (and behind your back) and finding an expression that it doesn't understand, considering the query to be invalid.

So if like me you want to be able to simply send a string to the database and let it deal with it (and let the developer take full responsibility for security), forget it.

Of course you could code an extension to allow that in some way or another, but you just as well off using mysqli to do it and leave Doctrine to it's ORM buisness.

Try this:

var request = WebRequest.Create("http://www.gravatar.com/avatar/6810d91caff032b202c50701dd3af745?d=identicon&r=PG");

using (var response = request.GetResponse())
using (var stream = response.GetResponseStream())
{
    pictureBox1.Image = Bitmap.FromStream(stream);
}

It is 2⁵³ == 9 007 199 254 740 992. This is because Numbers are stored as floating-point in a 52-bit mantissa.

The min value is -2⁵³.

This makes some fun things happening

Math.pow(2, 53) == Math.pow(2, 53) + 1
>> true

And can also be dangerous :)

var MAX_INT = Math.pow(2, 53); // 9 007 199 254 740 992
for (var i = MAX_INT; i < MAX_INT + 2; ++i) {
    // infinite loop
}

I'd just like to add to the very helpful answer from Kurt Pfeifle - there is now a Python wrapper for Tabula, and this seems to work very well so far: https://github.com/chezou/tabula-py

This will convert your PDF table to a Pandas data frame. You can also set the area in x,y co-ordinates which is obviously very handy for irregular data.

First of all, I don't see the reason for having an ID that's not unique, but I guess it's an ID that connects to another table. Second there is no need for subqueries, which beats up the server. You do this in one query, like this

SELECT id,GROUP_CONCAT(name, ':', value SEPARATOR "|") FROM sample GROUP BY id

You get fast and correct results, and you can split the result by that SEPARATOR "|". I always use this separator, because it's impossible to find it inside a string, therefor it's unique. There is no problem having two A's, you identify only the value. Or you can have one more colum, with the letter, which is even better. Like this :

SELECT id,GROUP_CONCAT(DISTINCT(name)), GROUP_CONCAT(value SEPARATOR "|") FROM sample GROUP BY name

On x86/x64 processors, a byte is 8 bits, and there are 256 possible binary states in 8 bits, 0 thru 255. This is how the OS translates your keyboard key strokes into letters on the screen. When you press the 'A' key, the keyboard sends a binary signal equal to the number 97 to the computer, and the computer prints a lowercase 'a' on the screen. You can confirm this in any Windows text editing software by holding an ALT key, typing 97 on the NUMPAD, then releasing the ALT key. If you replace '97' with any number from 0 to 255, you will see the character associated with that number on the system's character code page printed on the screen.

If a character is 8 bits, or 1 byte, then a WORD must be at least 2 characters, so 16 bits or 2 bytes. Traditionally, you might think of a word as a varying number of characters, but in a computer, everything that is calculable is based on static rules. Besides, a computer doesn't know what letters and symbols are, it only knows how to count numbers. So, in computer language, if a WORD is equal to 2 characters, then a double-word, or DWORD, is 2 WORDs, which is the same as 4 characters or bytes, which is equal to 32 bits. Furthermore, a quad-word, or QWORD, is 2 DWORDs, same as 4 WORDs, 8 characters, or 64 bits.

Note that these terms are limited in function to the Windows API for developers, but may appear in other circumstances (eg. the Linux dd command uses numerical suffixes to compound byte and block sizes, where c is 1 byte and w is bytes).

Check out this one, it's open source http://amateras.sourceforge.jp/cgi-bin/fswiki_en/wiki.cgi?page=EclipseHTMLEditor

According to a user on PHP.net site, his efforts to keep session alive failed, so he had to make a workaround.

<?php

$Lifetime = 3600;
$separator = (strstr(strtoupper(substr(PHP_OS, 0, 3)), "WIN")) ? "\\" : "/";

$DirectoryPath = dirname(__FILE__) . "{$separator}SessionData";
//in Wamp for Windows the result for $DirectoryPath
//would be C:\wamp\www\your_site\SessionData

is_dir($DirectoryPath) or mkdir($DirectoryPath, 0777);

if (ini_get("session.use_trans_sid") == true) {
    ini_set("url_rewriter.tags", "");
    ini_set("session.use_trans_sid", false);

}

ini_set("session.gc_maxlifetime", $Lifetime);
ini_set("session.gc_divisor", "1");
ini_set("session.gc_probability", "1");
ini_set("session.cookie_lifetime", "0");
ini_set("session.save_path", $DirectoryPath);
session_start();

?>

In SessionData folder it will be stored text files for holding session information, each file would be have a name similar to "sess_a_big_hash_here".

show user

to get connected user

 select instance_name from v$instance

to get instance or set in sqlplus

set sqlprompt "_USER'@'_CONNECT_IDENTIFIER> "

On Windows and Linux, press Ctrl+K, then release the keys and press O (the letter O, not Zero).

On macOS, press command+K, then O (without holding command).

This will open the active file tab in a new window/instance.

Python 3:

The official csv documentation recommends opening the file with newline='' on all platforms to disable universal newlines translation:

with open('output.csv', 'w', newline='', encoding='utf-8') as f:
    writer = csv.writer(f)
    ...

The CSV writer terminates each line with the lineterminator of the dialect, which is \r\n for the default excel dialect on all platforms.

Python 2:

On Windows, always open your files in binary mode ("rb" or "wb"), before passing them to csv.reader or csv.writer.

Although the file is a text file, CSV is regarded a binary format by the libraries involved, with \r\n separating records. If that separator is written in text mode, the Python runtime replaces the \n with \r\n, hence the \r\r\n observed in the file.

See this previous answer.

Below applies to all tags with the following two classes

.abc.xyz {  
  width: 200px !important;
}

applies to div tags with the following two classes

div.abc.xyz {  
  width: 200px !important;
}

If you wanted to modify this using jQuery

$(document).ready(function() {
  $("div.abc.xyz").width("200px");
});

I faced the same issue and It is really strange that the same code works in few case whereas it failed in some random cases.

I got it fixed by just making sure the proper setter/getter (Making sure the case sensitivity)

If you want to append instead of replace the output file, you may want to use

dir 1>> files.txt 2>> err.txt

or

dir 1>> files.txt 2>>&1

Old question but worth adding an answer if using .NET Core 3.0 or later. JSON serialization/deserialization is built into the framework (System.Text.Json), so you don't have to use third party libraries any more. Here's an example based off the top answer given by @Icarus

using System;
using System.Collections.Generic;

namespace ConsoleApp
{
    class Program
    {
        static void Main(string[] args)
        {
            var json = "[{\"Name\":\"John Smith\", \"Age\":35}, {\"Name\":\"Pablo Perez\", \"Age\":34}]";

            // use the built in Json deserializer to convert the string to a list of Person objects
            var people = System.Text.Json.JsonSerializer.Deserialize<List<Person>>(json);

            foreach (var person in people)
            {
                Console.WriteLine(person.Name + " is " + person.Age + " years old.");
            }
        }

        public class Person
        {
            public int Age { get; set; }
            public string Name { get; set; }
        }
    }
}

Just to clearify, in /etc/nginx/nginx.conf, you can put at the beginning of the file the line

error_log /var/log/nginx/error.log debug;

And then restart nginx:

sudo service nginx restart

That way you can detail what nginx is doing and why it is returning the status code 400.

Storing a list of object instances is very simple

class MyClass(object):
    def __init__(self, number):
        self.number = number

my_objects = []

for i in range(100):
    my_objects.append(MyClass(i))

# later

for obj in my_objects:
    print obj.number

The other answers to this question all miss the key point that in Java, there is one mutex associated with every object. (I'm assuming you know what a mutex or "lock" is.) This is not the case in most programming languages which have the concept of "locks". For example, in Ruby, you have to explicitly create as many Mutex objects as you need.

I think I know why the creators of Java made this choice (although, in my opinion, it was a mistake). The reason has to do with the inclusion of the synchronized keyword. I believe that the creators of Java (naively) thought that by including synchronized methods in the language, it would become easy for people to write correct multithreaded code -- just encapsulate all your shared state in objects, declare the methods that access that state as synchronized, and you're done! But it didn't work out that way...

Anyways, since any class can have synchronized methods, there needs to be one mutex for each object, which the synchronized methods can lock and unlock.

wait and notify both rely on mutexes. Maybe you already understand why this is the case... if not I can add more explanation, but for now, let's just say that both methods need to work on a mutex. Each Java object has a mutex, so it makes sense that wait and notify can be called on any Java object. Which means that they need to be declared as methods of Object.

Another option would have been to put static methods on Thread or something, which would take any Object as an argument. That would have been much less confusing to new Java programmers. But they didn't do it that way. It's much too late to change any of these decisions; too bad!

There are the slideDown, slideUp, and slideToggle functions native to jquery 1.3+, and they work quite nicely...

https://api.jquery.com/category/effects/

You can use slideDown just like this:

$("test").slideDown("slow");

And if you want to combine effects and really go nuts I'd take a look at the animate function which allows you to specify a number of CSS properties to shape tween or morph into. Pretty fancy stuff, that.

A more informative question is what makes code not thread safe- and the answer is that there are four conditions that must be true... Imagine the following code (and it's machine language translation)

totalRequests = totalRequests + 1
MOV EAX, [totalRequests]   // load memory for tot Requests into register
INC EAX                    // update register
MOV [totalRequests], EAX   // store updated value back to memory

1. The first condition is that there are memory locations that are accessible from more than one thread. Typically, these locations are global/static variables or are heap memory reachable from global/static variables. Each thread gets it's own stack frame for function/method scoped local variables, so these local function/method variables, otoh, (which are on the stack) are accessible only from the one thread that owns that stack.
2. The second condition is that there is a property (often called an invariant), which is associated with these shared memory locations, that must be true, or valid, for the program to function correctly. In the above example, the property is that “totalRequests must accurately represent the total number of times any thread has executed any part of the increment statement”. Typically, this invariant property needs to hold true (in this case, totalRequests must hold an accurate count) before an update occurs for the update to be correct.
3. The third condition is that the invariant property does NOT hold during some part of the actual update. (It is transiently invalid or false during some portion of the processing). In this particular case, from the time totalRequests is fetched until the time the updated value is stored, totalRequests does not satisfy the invariant.
4. The fourth and final condition that must occur for a race to happen (and for the code to therefore NOT be "thread-safe") is that another thread must be able to access the shared memory while the invariant is broken, thereby causing inconsistent or incorrect behavior.

I know this is really old, but I'm posting my solution anyways since google finds this thread.

background-image: url('./imagefolder/image.jpg');

That is what I do. Two dots means drill back one directory closer to root ".." while one "." should mean start where you are at as if it were root. I was having similar issues but adding that fixed it for me. You can even leave the "." in it when uploading to your host because it should work fine so long as your directory setup is exactly the same.

getActivity() is used for fragment. For activity, wherever you can use this, you can replace the this in fragment in similar cases with getActivity().

For now, semantically closest one would be a tuple with fixed number of elements.

typealias buffer = (
    SKSpriteNode, SKSpriteNode, SKSpriteNode, SKSpriteNode,
    SKSpriteNode, SKSpriteNode, SKSpriteNode, SKSpriteNode,
    SKSpriteNode, SKSpriteNode, SKSpriteNode, SKSpriteNode,
    SKSpriteNode, SKSpriteNode, SKSpriteNode, SKSpriteNode,
    SKSpriteNode, SKSpriteNode, SKSpriteNode, SKSpriteNode,

But this is (1) very uncomfortable to use and (2) memory layout is undefined. (at least unknown to me)

Here is a complete answer from hmkcode.com

If we have such JSON data

// JSON Data
var articles = [
    { 
        "title":"Title 1",
        "url":"URL 1",
        "categories":["jQuery"],
        "tags":["jquery","json","$.each"]
    },
    {
        "title":"Title 2",
        "url":"URL 2",
        "categories":["Java"],
        "tags":["java","json","jquery"]
    }
];

And we want to view in this Table structure

<table id="added-articles" class="table">
            <tr>
                <th>Title</th>
                <th>Categories</th>
                <th>Tags</th>
            </tr>
        </table>

The following JS code will fill create a row for each JSON element

// 1. remove all existing rows
$("tr:has(td)").remove();

// 2. get each article
$.each(articles, function (index, article) {

    // 2.2 Create table column for categories
    var td_categories = $("<td/>");

    // 2.3 get each category of this article
    $.each(article.categories, function (i, category) {
        var span = $("<span/>");
        span.text(category);
        td_categories.append(span);
    });

    // 2.4 Create table column for tags
   var td_tags = $("<td/>");

    // 2.5 get each tag of this article    
    $.each(article.tags, function (i, tag) {
        var span = $("<span/>");
        span.text(tag);
        td_tags.append(span);
    });

    // 2.6 Create a new row and append 3 columns (title+url, categories, tags)
    $("#added-articles").append($('<tr/>')
            .append($('<td/>').html("<a href='"+article.url+"'>"+article.title+"</a>"))
            .append(td_categories)
            .append(td_tags)
    ); 
});  

In owl carousel 2 you can use font-awesome icons or any custom images in navText option like this:

$(".category-wrapper").owlCarousel({
     items: 4,
     loop: true,
     margin: 30,
     nav: true,
     smartSpeed: 900,
     navText: ["<i class='fa fa-chevron-left'></i>","<i class='fa fa-chevron-right'></i>"]
});

A static variable declared in a header file outside of the class would be file-scoped in every .c file which includes the header. That means separate copy of a variable with same name is accessible in each of the .c files where you include the header file.

A static class variable on the other hand is class-scoped and the same static variable is available to every compilation unit that includes the header containing the class with static variable.

If your values are coming from the database, show selected values in that way.

<div class="form-group">
    <label for="status">Status</label>
    <select class="form-control" name="status" [(ngModel)]="category.status">
       <option [value]="1" [selected]="category.status ==1">Active</option>
       <option [value]="0" [selected]="category.status ==0">In Active</option>
    </select>
</div>

You can also do this:

wget -O - https://raw.github.com/luismartingil/commands/master/101_remote2local_wireshark.sh | bash

In C++:

#include <limits>

then use

int imin = std::numeric_limits<int>::min(); // minimum value
int imax = std::numeric_limits<int>::max();

std::numeric_limits is a template type which can be instantiated with other types:

float fmin = std::numeric_limits<float>::min(); // minimum positive value
float fmax = std::numeric_limits<float>::max();

In C:

#include <limits.h>

then use

int imin = INT_MIN; // minimum value
int imax = INT_MAX;

or

#include <float.h>

float fmin = FLT_MIN;  // minimum positive value
double dmin = DBL_MIN; // minimum positive value

float fmax = FLT_MAX;
double dmax = DBL_MAX;

Simply difference between Forward(ServletRequest request, ServletResponse response) and sendRedirect(String url) is

forward():

1. The forward() method is executed in the server side.
2. The request is transfer to other resource within same server.
3. It does not depend on the client’s request protocol since the forward () method is provided by the servlet container.
4. The request is shared by the target resource.
5. Only one call is consumed in this method.
6. It can be used within server.
7. We cannot see forwarded message, it is transparent.
8. The forward() method is faster than sendRedirect() method.
9. It is declared in RequestDispatcher interface.

sendRedirect():

1. The sendRedirect() method is executed in the client side.
2. The request is transfer to other resource to different server.
3. The sendRedirect() method is provided under HTTP so it can be used only with HTTP clients.
4. New request is created for the destination resource.
5. Two request and response calls are consumed.
6. It can be used within and outside the server.
7. We can see redirected address, it is not transparent.
8. The sendRedirect() method is slower because when new request is created old request object is lost.
9. It is declared in HttpServletResponse.

This post pertains to R proxy issues on *nix. You should know that R has many libraries/methods to fetch data over internet.

For 'curl', 'libcurl', 'wget' etc, just do the following:

1. Open a terminal. Type the following command:

   sudo gedit /etc/R/Renviron.site
   

2. Enter the following lines:

   http_proxy='http://username:[email protected]:port/'
   https_proxy='https://username:[email protected]:port/'
   

   Replace username, password, abc.com, xyz.com and port with these settings specific to your network.

3. Quit R and launch again.

This should solve your problem with 'libcurl' and 'curl' method. However, I have not tried it with 'httr'. One way to do that with 'httr' only for that session is as follows:

library(httr)
set_config(use_proxy(url="abc.com",port=8080, username="username", password="password"))

You need to substitute settings specific to your n/w in relevant fields.

The array declaration should be:

Car[] garage = new Car[100];

You can also just assign directly:

garage[1] = new Car("Blue");

I encountered the same error message but don't have any access to the table like "dba_free_space" because I am not a dba. I use some previous answers to check available space and I still have a lot of space. However, after reducing the full table scan as many as possible. The problem is solved. My guess is that Oracle uses temp table to store the full table scan data. It the data size exceeds the limit, it will show the error. Hope this helps someone with the same issue

Run a custom maven command in Eclipse as follows:

1. Right-click the maven project or pom.xml
2. Expand Run As
3. Select Maven Build...
4. Set Goals to the command, such as: clean install -X

Note: Eclipse prefixes the command with mvn automatically.

From the session_destroy() page in the PHP manual:

<?php
// Initialize the session.
// If you are using session_name("something"), don't forget it now!
session_start();

// Unset all of the session variables.
$_SESSION = array();

// If it's desired to kill the session, also delete the session cookie.
// Note: This will destroy the session, and not just the session data!
if (ini_get("session.use_cookies")) {
    $params = session_get_cookie_params();
    setcookie(session_name(), '', time() - 42000,
        $params["path"], $params["domain"],
        $params["secure"], $params["httponly"]
    );
}

// Finally, destroy the session.
session_destroy();
?>

This works for me https://www.nuget.org/packages/ASquare.WindowsTaskScheduler/

It is nicely designed Fluent API.

//This will create Daily trigger to run every 10 minutes for a duration of 18 hours
SchedulerResponse response = WindowTaskScheduler
    .Configure()
    .CreateTask("TaskName", "C:\\Test.bat")
    .RunDaily()
    .RunEveryXMinutes(10)
    .RunDurationFor(new TimeSpan(18, 0, 0))
    .SetStartDate(new DateTime(2015, 8, 8))
    .SetStartTime(new TimeSpan(8, 0, 0))
    .Execute();

For me, what caused this error was that I accidentally had the same message being sent twice to the same class member. When I right clicked on the button in the gui, I could see the method name twice, and I just deleted one. Newbie mistake in my case for sure, but wanted to get it out there for other newbies to consider.

In case anybody trying to run the automated unit tests via maven-surefire-plugin on CI(jenkins,..), and getting the above mentioned error, be sure to update your surefire plugin configuration :

It isn't exactly a ZIP, but the only way to compress a file using Windows tools is:

makecab <source> <dest>.cab

To decompress:

expand <source>.cab <dest>

Advanced example (from ss64.com):

Create a self extracting archive containing movie.mov:
C:\> makecab movie.mov "temp.cab"
C:\> copy /b "%windir%\system32\extrac32.exe"+"temp.cab" "movie.exe"
C:\> del /q /f "temp.cab"

There is no semicolon at the end of that instruction causing the error.

EDIT

Like RiverC pointed out, there is no semicolon at the end of the previous line!

require ("scripts/connect.php") 

EDIT

It seems you have no-semicolons whatsoever.

http://php.net/manual/en/language.basic-syntax.instruction-separation.php

As in C or Perl, PHP requires instructions to be terminated with a semicolon at the end of each statement.

you can try it too:

$(document).ajaxError(
    function (event, jqXHR, ajaxSettings, thrownError) {
        alert('[event:' + event + '], [jqXHR:' + jqXHR + '], [ajaxSettings:' + ajaxSettings + '], [thrownError:' + thrownError + '])');
    });

Chrome 30> supports video alpha transparency.

http://updates.html5rocks.com/2013/07/Alpha-transparency-in-Chrome-video

In general, you can't; you have to write the whole file again (at least from the point of change to the end).

In some specific cases you can do better than this -

if all your data elements are the same length and in no specific order, and you know the offset of the one you want to get rid of, you could copy the last item over the one to be deleted and truncate the file before the last item;

or you could just overwrite the data chunk with a 'this is bad data, skip it' value or keep a 'this item has been deleted' flag in your saved data elements such that you can mark it deleted without otherwise modifying the file.

This is probably overkill for short documents (anything under 100 KB?).

For ignoring all warnings use this sample, on the top of your code :

error_reporting(0);

BigDecimal(19.0001).setScale(2, BigDecimal.RoundingMode.DOWN)

As Ennui mentioned, IE 10 supports the -ms prefixed version of Flexbox (IE 11 supports it unprefixed). The errors I can see in your code are:

• You should have display: -ms-flexbox instead of display: -ms-flex
• I think you should specify all 3 flex values, like flex: 0 1 auto to avoid ambiguity

So the final updated code is...

.flexbox form {
    display: -webkit-flex;
    display: -moz-flex;
    display: -ms-flexbox;
    display: -o-flex;
    display: flex;

    /* Direction defaults to 'row', so not really necessary to specify */
    -webkit-flex-direction: row;
    -moz-flex-direction: row;
    -ms-flex-direction: row;
    -o-flex-direction: row;
    flex-direction: row;
}

.flexbox form input[type=submit] {
    width: 31px;
}

.flexbox form input[type=text] {
    width: auto;

    /* Flex should have 3 values which is shorthand for 
       <flex-grow> <flex-shrink> <flex-basis> */
    -webkit-flex: 1 1 auto;
    -moz-flex: 1 1 auto;
    -ms-flex: 1 1 auto;
    -o-flex: 1 1 auto;
    flex: 1 1 auto;

    /* I don't think you need 'display: flex' on child elements * /
    display: -webkit-flex;
    display: -moz-flex;
    display: -ms-flex;
    display: -o-flex;
    display: flex;
    /**/
}

After doing some research, it seems I cannot have two connections opened to the same database with the TransactionScope block. I needed to modify my code to look like this:

public void MyAddUpdateMethod()
{
    using (TransactionScope Scope = new TransactionScope(TransactionScopeOption.RequiresNew))
    {
        using(SQLServer Sql = new SQLServer(this.m_connstring))
        {
            //do my first add update statement            
        }

        //removed the method call from the first sql server using statement
        bool DoesRecordExist = this.SelectStatementCall(id)
    }
}

public bool SelectStatementCall(System.Guid id)
{
    using(SQLServer Sql = new SQLServer(this.m_connstring))
    {
        //create parameters
    }
}

Yep, Use a better option source filter. If you're searching with JSON it'll look something like this:

{
    "_source": ["user", "message", ...],
    "query": ...,
    "size": ...
}

In ES 2.4 and earlier, you could also use the fields option to the search API:

{
    "fields": ["user", "message", ...],
    "query": ...,
    "size": ...
}

This is deprecated in ES 5+. And source filters are more powerful anyway!

Here's an example of how to do it in C.

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

void segfault_sigaction(int signal, siginfo_t *si, void *arg)
{
    printf("Caught segfault at address %p\n", si->si_addr);
    exit(0);
}

int main(void)
{
    int *foo = NULL;
    struct sigaction sa;

    memset(&sa, 0, sizeof(struct sigaction));
    sigemptyset(&sa.sa_mask);
    sa.sa_sigaction = segfault_sigaction;
    sa.sa_flags   = SA_SIGINFO;

    sigaction(SIGSEGV, &sa, NULL);

    /* Cause a seg fault */
    *foo = 1;

    return 0;
}

Just throwing this out there - easy to now copy/paste into a word or google doc:

PRINT '<html><body>'
SET NOCOUNT ON
DECLARE @tableName VARCHAR(30)
DECLARE tableCursor CURSOR LOCAL FAST_FORWARD FOR
    SELECT T.name AS TableName 
      FROM sys.objects AS T
     WHERE T.type_desc = 'USER_TABLE'
     ORDER BY T.name
OPEN tableCursor
FETCH NEXT FROM tableCursor INTO @tableName
WHILE @@FETCH_STATUS = 0 BEGIN
    PRINT '<h2>' + @tableName + '</h2>'
    PRINT '<pre>'
    SELECT LEFT(C.name, 30) AS ColumnName,
           LEFT(ISC.DATA_TYPE, 10) AS DataType,
           C.max_length AS Size,
           CAST(P.precision AS VARCHAR(4)) + '/' + CAST(P.scale AS VARCHAR(4)) AS PrecScale,
           CASE WHEN C.is_nullable = 1 THEN 'Null' ELSE 'No Null' END AS [Nullable],
           LEFT(ISNULL(ISC.COLUMN_DEFAULT, ' '), 5)  AS [Default],
           CASE WHEN C.is_identity = 1 THEN 'Identity' ELSE '' END AS [Identity]
    FROM   sys.objects AS T
           JOIN sys.columns AS C ON T.object_id = C.object_id
           JOIN sys.types AS P ON C.system_type_id = P.system_type_id
           JOIN INFORMATION_SCHEMA.COLUMNS AS ISC ON T.name = ISC.TABLE_NAME AND C.name = ISC.COLUMN_NAME
    WHERE  T.type_desc = 'USER_TABLE'
      AND  T.name = @tableName
    ORDER BY T.name, ISC.ORDINAL_POSITION
    PRINT '</pre>'
    FETCH NEXT FROM tableCursor INTO @tableName

END

CLOSE tableCursor
DEALLOCATE tableCursor
SET NOCOUNT OFF
PRINT '</body></html>'

Great solution, thank you! I took the AndyDBell's question and Cuong Le's answer to build an example with two diferent interface's implementation:

public interface ISample
{
    int SampleId { get; set; }
}

public class Sample1 : ISample
{
    public int SampleId { get; set; }
    public Sample1() { }
}


public class Sample2 : ISample
{
    public int SampleId { get; set; }
    public String SampleName { get; set; }
    public Sample2() { }
}

public class SampleGroup
{
    public int GroupId { get; set; }
    public IEnumerable<ISample> Samples { get; set; }
}

class Program
{
    static void Main(string[] args)
    {
        //Sample1 instance
        var sz = "{\"GroupId\":1,\"Samples\":[{\"SampleId\":1},{\"SampleId\":2}]}";
        var j = JsonConvert.DeserializeObject<SampleGroup>(sz, new SampleConverter<Sample1>());
        foreach (var item in j.Samples)
        {
            Console.WriteLine("id:{0}", item.SampleId);
        }
        //Sample2 instance
        var sz2 = "{\"GroupId\":1,\"Samples\":[{\"SampleId\":1, \"SampleName\":\"Test1\"},{\"SampleId\":2, \"SampleName\":\"Test2\"}]}";
        var j2 = JsonConvert.DeserializeObject<SampleGroup>(sz2, new SampleConverter<Sample2>());
        //Print to show that the unboxing to Sample2 preserved the SampleName's values
        foreach (var item in j2.Samples)
        {
            Console.WriteLine("id:{0} name:{1}", item.SampleId, (item as Sample2).SampleName);
        }
        Console.ReadKey();
    }
}

And a generic version to the SampleConverter:

public class SampleConverter<T> : CustomCreationConverter<ISample> where T: new ()
{
    public override ISample Create(Type objectType)
    {
        return ((ISample)new T());
    }
}

Have a look at the rack-cors middleware. It will handle CORS headers in a configurable manner.

As Gerben suggested, just change:

order deny,allow
deny from all

to

order allow,deny

And the restrictions will work as you want them to.

Details can be found in Apache's docs.

IIUC, if you make your (unfortunately named) List into an ndarray, you can simply index into it naturally.

>>> import numpy as np
>>> m = np.arange(16)*10
>>> m[df.A]
array([  0,  40,  50,  60, 150, 150, 140, 130])
>>> df["D"] = m[df.A]
>>> df
    A   B   C    D
0   0 NaN NaN    0
1   4 NaN NaN   40
2   5 NaN NaN   50
3   6 NaN NaN   60
4  15 NaN NaN  150
5  15 NaN NaN  150
6  14 NaN NaN  140
7  13 NaN NaN  130

Here I built a new m, but if you use m = np.asarray(List), the same thing should work: the values in df.A will pick out the appropriate elements of m.

Note that if you're using an old version of numpy, you might have to use m[df.A.values] instead-- in the past, numpy didn't play well with others, and some refactoring in pandas caused some headaches. Things have improved now.

I have reformatted your slow sql query with www.prettysql.net

SELECT *
FROM some_table
WHERE
 relevant_field in
 (
  SELECT relevant_field
  FROM some_table
  GROUP BY relevant_field
  HAVING COUNT ( * ) > 1
 );

When using a table in both the query and the subquery, you should always alias both, like this:

SELECT *
FROM some_table as t1
WHERE
 t1.relevant_field in
 (
  SELECT t2.relevant_field
  FROM some_table as t2
  GROUP BY t2.relevant_field
  HAVING COUNT ( t2.relevant_field ) > 1
 );

Does that help?

Go to designer.cs file of the form in which you have the grid view and comment the following line: - //this.dataGridView1.AlternatingRowsDefaultCellStyle = dataGridViewCellStyle1;

if you are using vs 2008 or .net framework 3.5 as it will be by default applied to alternating rows.

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

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

Update:

Two possible solutions:

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

To fetch even records

select *
from (select id,row_number() over (order by id) as r from table_name) T
where mod(r,2)=0;

To fetch odd records

select *
from (select id,row_number() over (order by id) as r from table_name) T
where mod(r,2)=1;

Here are the different ways in which you can create an array of booleans in typescript:

let arr1: boolean[] = [];
let arr2: boolean[] = new Array();
let arr3: boolean[] = Array();

let arr4: Array<boolean> = [];
let arr5: Array<boolean> = new Array();
let arr6: Array<boolean> = Array();

let arr7 = [] as boolean[];
let arr8 = new Array() as Array<boolean>;
let arr9 = Array() as boolean[];

let arr10 = <boolean[]> [];
let arr11 = <Array<boolean>> new Array();
let arr12 = <boolean[]> Array();

let arr13 = new Array<boolean>();
let arr14 = Array<boolean>();

You can access them using the index:

console.log(arr[5]);

and you add elements using push:

arr.push(true);

When creating the array you can supply the initial values:

let arr1: boolean[] = [true, false];
let arr2: boolean[] = new Array(true, false);

For repeating an action in the future, there is the built in setInterval function that you can use instead of setTimeout.
It has a similar signature, so the transition from one to another is simple:

setInterval(function() {
    // do stuff
}, duration);

If all you want to do is display the date with a specific format, just call:

@String.Format(myFormat, Model.MyDateTime)

Using @Html.DisplayFor(...) is just extra work unless you are specifying a template, or need to use something that is built on templates, like iterating an IEnumerable<T>. Creating a template is simple enough, and can provide a lot of flexibility too. Create a folder in your views folder for the current controller (or shared views folder) called DisplayTemplates. Inside that folder, add a partial view with the model type you want to build the template for. In this case I added /Views/Shared/DisplayTemplates and added a partial view called ShortDateTime.cshtml.

@model System.DateTime

@Model.ToShortDateString()

And now you can call that template with the following line:

@Html.DisplayFor(m => m.MyDateTime, "ShortDateTime")

This is all perfectly normal. Microsoft added sequences in SQL Server 2012, finally, i might add and changed the way identity keys are generated. Have a look here for some explanation.

If you want to have the old behaviour, you can:

1. use trace flag 272 - this will cause a log record to be generated for each generated identity value. The performance of identity generation may be impacted by turning on this trace flag.
2. use a sequence generator with the NO CACHE setting (http://msdn.microsoft.com/en-us/library/ff878091.aspx)

Use the below code. This should work.

$comments = EmailArchive::find()->where(['email_id' => $id])->all();

files directory:

Project->

-functions.php

-main.php

functions.php

function sum(a,b){
 return a+b;
}
function product(a,b){
return a*b;
}

main.php

require_once "functions.php";
echo "sum of two numbers ". sum(4,2);
echo "<br>"; //  create break line
echo "product of two numbers ".product(2,3);

The Output Is :

sum of two numbers 6 product of two numbers 6

Note: don't write public before function. Public, private, these modifiers can only use when you create class.

For me, the problem was caused by the hosting company (Godaddy) treating POST operations which had substantial response data (anything more than tens of kilobytes) as some sort of security threat. If more than 6 of these occurred in one minute, the host refused to execute the PHP code that responded to the POST request during the next minute. I'm not entirely sure what the host did instead, but I did see, with tcpdump, a TCP reset packet coming as the response to a POST request from the browser. This caused the http status code returned in a jqXHR object to be 0.

Changing the operations from POST to GET fixed the problem. It's not clear why Godaddy impose this limit, but changing the code was easier than changing the host.

Just happened to me after upgrading to Android Studio 3.1. The Offline Work checkbox was unchecked, so no luck there.

I went to Settings > Build, Execution, Deployment > Compiler and the Command-line Options textfield contained --offline, so I just deleted that and everything worked.

To change the size of (almost) all text elements, in one place, and synchronously, rel() is quite efficient:
g+theme(text = element_text(size=rel(3.5))

You might want to tweak the number a bit, to get the optimum result. It sets both the horizontal and vertical axis labels and titles, and other text elements, on the same scale. One exception is faceted grids' titles which must be manually set to the same value, for example if both x and y facets are used in a graph:
theme(text = element_text(size=rel(3.5)), strip.text.x = element_text(size=rel(3.5)), strip.text.y = element_text(size=rel(3.5)))

Your data structure and your JSON do not match.

Your JSON is this:

{
    "JsonValues":{
        "id": "MyID",
        ...
    }
}

But the data structure you try to serialize it to is this:

class ValueSet
{
    [JsonProperty("id")]
    public string id
    {
        get;
        set;
    }
    ...
}

You are skipping a step: Your JSON is a class that has one property named JsonValues, which has an object of your ValueSet data structure as value.

Also inside your class your JSON is this:

"values": { ... }

Your data structure is this:

[JsonProperty("values")]
public List<Value> values
{
    get;
    set;
}

Note that { .. } in JSON defines an object, where as [ .. ] defines an array. So according to your JSON you don't have a bunch of values, but you have one values object with the properties value1 and value2 of type Value.

Since the deserializer expects an array but gets an object instead, it does the least non-destructive (Exception) thing it could do: skip the value. Your property values remains with it's default value: null.

If you can: Adjust your JSON. The following would match your data structure and is most likely what you actually want:

{
    "id": "MyID",

     "values": [
         {
            "id": "100",
            "diaplayName": "MyValue1"
         }, {
            "id": "200",
            "diaplayName": "MyValue2"
         }
     ]
}

As a general rule of thumb, if I have to set the value of the string more than once, or if there are any appends to the string, then it needs to be a string builder. I have seen applications that I have written in the past before learning about string builders that have had a huge memory foot print that just seems to keep growing and growing. Changing these programs to use the string builder cut down the memory usage significantly. Now I swear by the string builder.

You could use the PowerShell equivalent of String.Format - it's usually the easiest way to build up a string. Place {0}, {1}, etc. where you want the variables in the string, put a -f immediately after the string and then the list of variables separated by commas.

Get-ChildItem c:\code|%{'{0}\{1}\{2}.dll' -f $_.fullname,$buildconfig,$_.name}

(I've also taken the dash out of the $buildconfig variable name as I have seen that causes issues before too.)

First, the valid syntax is

jQuery("input[name=ticketID]")

second, have you tried:

jQuery(":radio")

instead?

third, why not assign a class to all the radio buttons, and select them by class?

Tuples are compared position by position: the first item of the first tuple is compared to the first item of the second tuple; if they are not equal (i.e. the first is greater or smaller than the second) then that's the result of the comparison, else the second item is considered, then the third and so on.

See Common Sequence Operations:

Sequences of the same type also support comparisons. In particular, tuples and lists are compared lexicographically by comparing corresponding elements. This means that to compare equal, every element must compare equal and the two sequences must be of the same type and have the same length.

Also Value Comparisons for further details:

Lexicographical comparison between built-in collections works as follows:

• For two collections to compare equal, they must be of the same type, have the same length, and each pair of corresponding elements must compare equal (for example, [1,2] == (1,2) is false because the type is not the same).
• Collections that support order comparison are ordered the same as their first unequal elements (for example, [1,2,x] <= [1,2,y] has the same value as x <= y). If a corresponding element does not exist, the shorter collection is ordered first (for example, [1,2] < [1,2,3] is true).

If not equal, the sequences are ordered the same as their first differing elements. For example, cmp([1,2,x], [1,2,y]) returns the same as cmp(x,y). If the corresponding element does not exist, the shorter sequence is considered smaller (for example, [1,2] < [1,2,3] returns True).

Note 1: < and > do not mean "smaller than" and "greater than" but "is before" and "is after": so (0, 1) "is before" (1, 0).

Note 2: tuples must not be considered as vectors in a n-dimensional space, compared according to their length.

Note 3: referring to question https://stackoverflow.com/questions/36911617/python-2-tuple-comparison: do not think that a tuple is "greater" than another only if any element of the first is greater than the corresponding one in the second.

I found that for me the best permanent solution to stay up-to-date under Linux was to install the R-patched project. This will keep your R installation up-to-date, and you needn't even move your packages between installations (which is described in RyanStochastic's answer).

For openSUSE, see the instructions here.

This may help:

function doAjax(url, callback) {
    var xmlhttp = window.XMLHttpRequest ? new XMLHttpRequest() : new ActiveXObject("Microsoft.XMLHTTP");

    xmlhttp.onreadystatechange = function() {
        if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
            callback(xmlhttp.responseText);
        }
    }

    xmlhttp.open("GET", url, true);
    xmlhttp.send();
}

Use the wc utility with the print the byte counts (-c) option:

$ SO="stackoverflow"
$ echo -n "$SO" | wc -c
    13

You'll have to use the do not output the trailing newline (-n) option for echo. Otherwise, the newline character will also be counted.

Please put your related value and try this :

declare @x int, @y varchar(200),
        @dt1 smalldatetime = '2014-01-21 10:00:00', 
        @dt2 smalldatetime = getdate()

set @x = datediff (HOUR, @dt1, @dt2)
set @y =  @x * 60 -  DATEDIFF(minute,@dt1, @dt2)
set @y = cast(@x as varchar(200)) + ':' + @y
Select @y

You can apply any CSS class on this tag.

I am using below solution but for that you have to install sshpass If its not already installed, install it using sudo apt install sshpass

Now you can do this,

sshpass -p *YourPassword* shh root@IP

You can create a bash alias as well so that you don't have to run the whole command again and again. Follow below steps

cd ~

sudo nano .bash_profile

at the end of the file add below code

mymachine() { sshpass -p *YourPassword* shh root@IP }

source .bash_profile

Now just run mymachine command from terminal and you'll enter your machine without password prompt.

Note:

1. mymachine can be any command of your choice.
2. If security doesn't matter for you here in this task and you just want to automate the work you can use this method.

If you try exec sp_rename and receieve a LockMatchID error then it might help to add a use [database] statement first:

I tried

 exec sp_rename '[database_name].[dbo].[table_name]', 'new_table_name';
 -- Invalid EXECUTE statement using object "Object", method "LockMatchID".

What I had to do to fix it was to rewrite it to:

use database_name
exec sp_rename '[dbo].[table_name]', 'new_table_name';

for testing purposes only you could Go to your facebook developer dashboard. create your app then in the top left corner open the apps dropdown menu and click create test app take the app ID and use instead.

I think it works the other way

<#if object.attribute??>
   Do whatever you want....
</#if>

If object.attribute is NOT NULL, then the content will be printed.

By HTML5 drafts, input type=time creates a control for time of the day input, expected to be implemented using “the user’s preferred presentation”. But this really means using a widget where time presentation follows the rules of the browser’s locale. So independently of the language of the surrounding content, the presentation varies by the language of the browser, the language of the underlying operating system, or the system-wide locale settings (depending on browser). For example, using a Finnish-language version of Chrome, I see the widget as using the standard 24-hour clock. Your mileage will vary.

Thus, input type=time are based on an idea of localization that takes it all out of the hands of the page author. This is intentional; the problem has been raised in HTML5 discussions several times, with the same outcome: no change. (Except possibly added clarifications to the text, making this behavior described as intended.)

Note that pattern and placeholder attributes are not allowed in input type=time. And placeholder="hrs:mins", if it were implemented, would be potentially misleading. It’s quite possible that the user has to type 12.30 (with a period) and not 12:30, when the browser locale uses “.” as a separator in times.

My conclusion is that you should use input type=text, with pattern attribute and with some JavaScript that checks the input for correctness on browsers that do not support the pattern attribute natively.

$.browser was removed from jQuery starting with version 1.9. It is now available as a plugin. It's generally recommended to avoid browser detection, which is why it was removed.

since HashMap implements Serializable interface, you can simply use ObjectOutputStream class to write whole Map to file, and read it again using ObjectInputStream class

below simple code that explain usage of ObjectOutStream and ObjectInputStream

import java.util.*;
import java.io.*;
public class A{

    HashMap<String,String> hm;
    public A() {
        hm=new HashMap<String,String>();

        hm.put("1","A");
        hm.put("2","B");
        hm.put("3","C");

        method1(hm);

    }

public void method1(HashMap<String,String> map) {
    //write to file : "fileone"
    try {
        File fileOne=new File("fileone");
        FileOutputStream fos=new FileOutputStream(fileOne);
        ObjectOutputStream oos=new ObjectOutputStream(fos);

        oos.writeObject(map);
        oos.flush();
        oos.close();
        fos.close();
    } catch(Exception e) {}

    //read from file 
    try {
        File toRead=new File("fileone");
        FileInputStream fis=new FileInputStream(toRead);
        ObjectInputStream ois=new ObjectInputStream(fis);

        HashMap<String,String> mapInFile=(HashMap<String,String>)ois.readObject();

        ois.close();
        fis.close();
        //print All data in MAP
        for(Map.Entry<String,String> m :mapInFile.entrySet()){
            System.out.println(m.getKey()+" : "+m.getValue());
        }
    } catch(Exception e) {}
  }

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

}

or if you want to write data as text to file you can simply iterate through Map and write key and value line by line, and read it again line by line and add to HashMap

import java.util.*;
import java.io.*;
public class A{

    HashMap<String,String> hm;
    public A(){
        hm=new HashMap<String,String>();

        hm.put("1","A");
        hm.put("2","B");
        hm.put("3","C");

        method2(hm);

    }

public void method2(HashMap<String,String> map) {
    //write to file : "fileone"
    try {
        File fileTwo=new File("filetwo.txt");
        FileOutputStream fos=new FileOutputStream(fileTwo);
        PrintWriter pw=new PrintWriter(fos);

        for(Map.Entry<String,String> m :map.entrySet()){
            pw.println(m.getKey()+"="+m.getValue());
        }

        pw.flush();
        pw.close();
        fos.close();
    } catch(Exception e) {}

    //read from file 
    try {
        File toRead=new File("filetwo.txt");
        FileInputStream fis=new FileInputStream(toRead);

        Scanner sc=new Scanner(fis);

        HashMap<String,String> mapInFile=new HashMap<String,String>();

        //read data from file line by line:
        String currentLine;
        while(sc.hasNextLine()) {
            currentLine=sc.nextLine();
            //now tokenize the currentLine:
            StringTokenizer st=new StringTokenizer(currentLine,"=",false);
            //put tokens ot currentLine in map
            mapInFile.put(st.nextToken(),st.nextToken());
        }
        fis.close();

        //print All data in MAP
        for(Map.Entry<String,String> m :mapInFile.entrySet()) {
            System.out.println(m.getKey()+" : "+m.getValue());
        }
    }catch(Exception e) {}
  }

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

}

NOTE: above code may not be the fastest way to doing this task, but i want to show some application of classes

See ObjectOutputStream , ObjectInputStream, HashMap, Serializable, StringTokenizer

That's a really insecure idea, but: Using the passwd command from within a shell script

Just try this. It's easy without any extra builtin functions.

#include <iostream>

int prime(int n,int r){

  for(int i=2;n<=r;i++){
    if(i==2 || i==3 || i==5 || i==7){
      std::cout<<i<<" ";
      n++;
    } else if(i%2==0 || i%3==0 || i%5==0 || i%7==0)
      continue;
    else {
      std::cout<<i<<" ";
      n++;
    }
  }

}

main(){

  prime(1,25);
}

Testing by 2,3,5,7 is good enough for up to 120, so 100 is OK.

There are 25 primes below 100, an 30 below 121 = 11*11.

Yes you can compare with the help of data like below code

UITableViewCell *cell = (UITableViewCell*)[self.view viewWithTag:indexPath.row + 100];

UIImage *secondImage = [UIImage imageNamed:@"boxhover.png"];

NSData *imgData1 = UIImagePNGRepresentation(cell.imageView.image);
NSData *imgData2 = UIImagePNGRepresentation(secondImage);

BOOL isCompare =  [imgData1 isEqual:imgData2];
if(isCompare)
{
    //contain same image
    cell.imageView.image = [UIImage imageNamed:@"box.png"];
}
else
{
    //does not contain same image
    cell.imageView.image = secondImage;
}

You first have to 'dot' source the script, so for you :

. .\Get-NetworkStatistics.ps1

The first 'dot' asks PowerShell to load the script file into your PowerShell environment, not to start it. You should also use set-ExecutionPolicy Unrestricted or set-ExecutionPolicy AllSigned see(the Execution Policy instructions).

As for security issues, here is what a security consultant will tell you on the whole field issue (this is from an actual independent security audit):

HTML Autocomplete Enabled – Password fields in HTML forms have autocomplete enabled. Most browsers have a facility to remember user credentials entered into HTML forms.

Relative Risk: Low

Affected Systems/Devices: o https://*******/

I also agree this should cover any field that contains truly private data. I feel that it is alright to force a person to always type their credit card information, CVC code, passwords, usernames, etc whenever that site is going to access anything that should be kept secure [universally or by legal compliance requirements]. For example: purchase forms, bank/credit sites, tax sites, medical data, federal, nuclear, etc - not Sites like Stack Overflow or Facebook.

Other types of sites - e.g. TimeStar Online for clocking in and out of work - it's stupid, since I always use the same PC/account at work, that I can't save the credentials on that site - strangely enough I can on my Android but not on an iPad. Even shared PCs this wouldn't be too bad since clocking in/out for someone else really doesn't do anything but annoy your supervisor. (They have to go in and delete the erroneous punches - just choose not to save on public PCs).

If you are using MS Word then try ALT+E, S, U, Enter (Uses the Paste Special)

If you can't update configuration files but control the code that handles file uploads use HttpContext.Current.Request.GetBufferlessInputStream(true).

The true value for disableMaxRequestLength parameter tells the framework to ignore configured request limits.

A pure CSS approach adding to solution of @jerseyboy above.

But take care, as @jerseyboy states in his comment:

Rescaling canvas with CSS is troublesome. At least on Chrome and Safari, mouse/touch event positions will not correspond 1:1 with canvas pixel positions, and you'll have to transform the coordinate systems.

I really like Vitaly Zinchenkos solution since it was short.

Here is an even briefer version in kotlin for a simple fade out

viewToAnimate?.alpha = 1f
viewToAnimate?.animate()
             ?.alpha(0f)
             ?.setDuration(1000)
             ?.setInterpolator(DecelerateInterpolator())
             ?.start()

If you are on Red Hat/CentOS:

# To allow for building python ssl libs
yum install openssl-devel
# Download the source of *any* python version
cd /usr/src
wget https://www.python.org/ftp/python/3.6.2/Python-3.6.2.tar.xz
tar xf Python-3.6.2.tar.xz 
cd Python-3.6.2

# Configure the build w/ your installed libraries
./configure

# Install into /usr/local/bin/python3.6, don't overwrite global python bin
make altinstall

In my case work that: I just wrote sudo before the command :

sudo npm run deploy

The new ASP.NET Web API is a continuation of the previous WCF Web API project (although some of the concepts have changed).

WCF was originally created to enable SOAP-based services. For simpler RESTful or RPCish services (think clients like jQuery) ASP.NET Web API should be good choice.

For us, WCF is used for SOAP and Web API for REST. I wish Web API supported SOAP too. We are not using advanced features of WCF. Here is comparison from MSDN:

ASP.net Web API is all about HTTP and REST based GET,POST,PUT,DELETE with well know ASP.net MVC style of programming and JSON returnable; web API is for all the light weight process and pure HTTP based components. For one to go ahead with WCF even for simple or simplest single web service it will bring all the extra baggage. For light weight simple service for ajax or dynamic calls always WebApi just solves the need. This neatly complements or helps in parallel to the ASP.net MVC.

Check out the podcast : Hanselminutes Podcast 264 - This is not your father's WCF - All about the WebAPI with Glenn Block by Scott Hanselman for more information.

In the scenarios listed below you should go for WCF:

1. If you need to send data on protocols like TCP, MSMQ or MIME
2. If the consuming client just knows how to consume SOAP messages

WEB API is a framework for developing RESTful/HTTP services.

There are so many clients that do not understand SOAP like Browsers, HTML5, in those cases WEB APIs are a good choice.

HTTP services header specifies how to secure service, how to cache the information, type of the message body and HTTP body can specify any type of content like HTML not just XML as SOAP services.

For the final, compiled code of your application, the short answer is “no”. Different tools are able to extract different information from the code (e.g. the forms setups) and there are P code decompilers (see Edgar's excellent link for such tools). However, up to this day, there is no decompiler for native code. I'm not aware of anything similar for other high-level languages either.

This code works to catch the user closing the console window:

using System;
using System.Runtime.InteropServices;

class Program {
    static void Main(string[] args) {
        handler = new ConsoleEventDelegate(ConsoleEventCallback);
        SetConsoleCtrlHandler(handler, true);
        Console.ReadLine();
    }

    static bool ConsoleEventCallback(int eventType) {
        if (eventType == 2) {
            Console.WriteLine("Console window closing, death imminent");
        }
        return false;
    }
    static ConsoleEventDelegate handler;   // Keeps it from getting garbage collected
    // Pinvoke
    private delegate bool ConsoleEventDelegate(int eventType);
    [DllImport("kernel32.dll", SetLastError = true)]
    private static extern bool SetConsoleCtrlHandler(ConsoleEventDelegate callback, bool add);

}

Beware of the restrictions. You have to respond quickly to this notification, you've got 5 seconds to complete the task. Take longer and Windows will kill your code unceremoniously. And your method is called asynchronously on a worker thread, the state of the program is entirely unpredictable so locking is likely to be required. Do make absolutely sure that an abort cannot cause trouble. For example, when saving state into a file, do make sure you save to a temporary file first and use File.Replace().

As mentioned in several answers already that have been already given, you can use ToShorDateString():

DateTime.Now.ToShortDateString();

However, you may be a bit blocked if you also want to use the culture as a parameter. In this case you can use the ToString() method with the "d" format:

DateTime.Now.ToString("d", CultureInfo.GetCultureInfo("en-US"))

I assume you're trying to tunnel into some unix box.

Make sure X11 forwarding is enabled in your PuTTY settings.

As others have pointed out, clone will do it. Be aware that clone of a hash makes a shallow copy. That is to say:

h1 = {:a => 'foo'} 
h2 = h1.clone
h1[:a] << 'bar'
p h2                # => {:a=>"foobar"}

What's happening is that the hash's references are being copied, but not the objects that the references refer to.

If you want a deep copy then:

def deep_copy(o)
  Marshal.load(Marshal.dump(o))
end

h1 = {:a => 'foo'}
h2 = deep_copy(h1)
h1[:a] << 'bar'
p h2                # => {:a=>"foo"}

deep_copy works for any object that can be marshalled. Most built-in data types (Array, Hash, String, &c.) can be marshalled.

Marshalling is Ruby's name for serialization. With marshalling, the object--with the objects it refers to--is converted to a series of bytes; those bytes are then used to create another object like the original.

The date function would be defined something like this:

function date($format, $timestamp = null)
{
    if ($timestamp === null) {
        $timestamp = time();
    }

    // Format the timestamp according to $format
}

Usually, you would put the default value like this:

function foo($required, $optional = 42)
{
    // This function can be passed one or more arguments
}

However, only literals are valid default arguments, which is why I used null as default argument in the first example, not $timestamp = time(), and combined it with a null check. Literals include arrays (array() or []), booleans, numbers, strings, and null.

three different approaches:

1. Classic client/server approach: don't put any database in the shops; simply have the applications access your server. Of course it's better if you set a VPN, but simply wrapping the connection in SSL or ssh is reasonable. Pro: it's the way databases were originally thought. Con: if you have high latency, complex operations could get slow, you might have to use stored procedures to reduce the number of round trips.

2. replicated master/master: as @Book Of Zeus suggested. Cons: somewhat more complex to setup (especially if you have several shops), breaking in any shop machine could potentially compromise the whole system. Pros: better responsivity as read operations are totally local and write operations are propagated asynchronously.

3. offline operations + sync step: do all work locally and from time to time (might be once an hour, daily, weekly, whatever) write a summary with all new/modified records from the last sync operation and send to the server. Pros: can work without network, fast, easy to check (if the summary is readable). Cons: you don't have real-time information.

PHP has its own inbuilt class that can be used to unzip or extracts contents from a zip file. The class is ZipArchive. Below is the simple and basic PHP code that will extract a zip file and place it in a specific directory:

<?php
$zip_obj = new ZipArchive;
$zip_obj->open('dummy.zip');
$zip_obj->extractTo('directory_name/sub_dir');
?>

If you want some advance features then below is the improved code that will check if the zip file exists or not:

<?php
$zip_obj = new ZipArchive;
if ($zip_obj->open('dummy.zip') === TRUE) {
   $zip_obj->extractTo('directory/sub_dir');
   echo "Zip exists and successfully extracted";
}
else {
   echo "This zip file does not exists";
}
?>

With library fpp, you can easily create time series with date format: time_ser=ts(data,frequency=4,start=c(1954,2))

here we start at the 2nd quarter of 1954 with quarter fequency.

The problem is that HTML doesn't recognize the escape character. You could work around that by using the single quotes for the HTML attribute and the double quotes for the onclick.

<a href="#" onclick='DoEdit("Preliminary Assessment \"Mini\""); return false;'>edit</a>

If you're using jackson, better to convert directly to ObjectNode.

//not including SerializationFeatures for brevity
static final ObjectMapper mapper = new ObjectMapper();

//pass it your payload
public static ObjectNode convObjToONode(Object o) {
    StringWriter stringify = new StringWriter();
    ObjectNode objToONode = null;

    try {
        mapper.writeValue(stringify, o);
        objToONode = (ObjectNode) mapper.readTree(stringify.toString());
    } catch (IOException e) {
        e.printStackTrace();
    }

    System.out.println(objToONode);
    return objToONode;
}

Casting to an int truncates the value. Adding 0.5 causes it to do proper rounding.

int y = (int)(x + 0.5);

Try:

android:lines="2"

\n should work.

Steps (1) Just Select your range, rows or column or array , (2) Press ctrl+H , (3 a) then in the find type a space (3 b) in the replace do not enter anything, (4)then just click on replace all..... you are done.

You should be using DATEADD is Sql server so if try this simple select you will see the affect

Select DATEADD(Month, -1, getdate())

Result

2013-04-20 14:08:07.177

in your case try this query

SELECT name
FROM (
SELECT name FROM 
Hist_answer
WHERE id_city='34324' AND datetime >= DATEADD(month,-1,GETDATE())
UNION ALL
SELECT name FROM 
Hist_internet
WHERE id_city='34324' AND datetime >= DATEADD(month,-1,GETDATE())
) x
GROUP BY name ORDER BY name

I had the same issue. In the Google APIs Console, you should check that there is only one key generated for that app. I had a stretch where I migrated my code from one PC to the next and so on (it got messy), and had multiple keys for my one project. The older keys are all listed as inactive on the API console page, but for some reason caused a conflict. After deleting them completely, I ran it again and it worked.

If you don't want to install anything but do want to download an SVN or GIT repository, then you can use this: http://downloadsvn.codeplex.com/

I have nothing to do with this project, but I just used it now and it saved me a few minutes. Maybe it will help someone.

So I know that this post is pretty old, but I figured I may as well add a function that has helped me over the years. Why not just remake the explode function using split as mentioned above? Well here it is:

function explode(str,begin,end)
{
   t=str.split(begin);
   t=t[1].split(end);
   return t[0];
}

This function works well if you are trying to get the values between two values. For instance:

data='[value]insertdataherethatyouwanttoget[/value]';

If you were interested in getting the information from between the two [values] "tags", you could use the function like the following.

out=explode(data,'[value]','[/value]');
//Variable out would display the string: insertdataherethatyouwanttoget

But let's say you don't have those handy "tags" like the example above displayed. No matter.

out=explode(data,'insert','wanttoget');
//Now out would display the string: dataherethatyou

Since my initial answer was criticised on the basis that my special-purpose constructors did not call the (unique) default constructor, I post here a modified version that honours the wishes that all constructors shall call the default one:

class Cheese:
    def __init__(self, *args, _initialiser="_default_init", **kwargs):
        """A multi-initialiser.
        """
        getattr(self, _initialiser)(*args, **kwargs)

    def _default_init(self, ...):
        """A user-friendly smart or general-purpose initialiser.
        """
        ...

    def _init_parmesan(self, ...):
        """A special initialiser for Parmesan cheese.
        """
        ...

    def _init_gouda(self, ...):
        """A special initialiser for Gouda cheese.
        """
        ...

    @classmethod
    def make_parmesan(cls, *args, **kwargs):
        return cls(*args, **kwargs, _initialiser="_init_parmesan")

    @classmethod
    def make_gouda(cls, *args, **kwargs):
        return cls(*args, **kwargs, _initialiser="_init_gouda")

For me it was missing MySQL PDO, I recompiled my PHP with the --with-pdo-mysql option, installed it and restarted apache and it was all working

The most safe way is probably overriding keys method that is used to generate output:

new JSONObject(){
  @Override
  public Iterator keys(){
    TreeSet<Object> sortedKeys = new TreeSet<Object>();
    Iterator keys = super.keys();
    while(keys.hasNext()){
      sortedKeys.add(keys.next());
    }
    return sortedKeys.iterator();
  }
};

Extracted from @Resord's comments above. This one worked for me and more closely inclined with the question.

$(this).parent().closest('.a');

Thanks

As far as i understood your issue is that you want to change the text of the button with the clicking linked text, if so you can try this one: http://jsbin.com/owuyix/4/edit

 $(function(){

    $(".dropdown-menu li a").click(function(){

      $(".btn:first-child").text($(this).text());
      $(".btn:first-child").val($(this).text());

   });

});

As per your comment:

this doesn't work for me when I have lists item <li> populated through ajax call.

so you have to delegate the event to the closest static parent with .on() jQuery method:

 $(function(){

    $(".dropdown-menu").on('click', 'li a', function(){
      $(".btn:first-child").text($(this).text());
      $(".btn:first-child").val($(this).text());
   });

});

Here event is delegated to static parent $(".dropdown-menu"), although you can delegate the event to the $(document) too because it is always available.

Socket connections in Android are the same as in Java: http://www.oracle.com/technetwork/java/socket-140484.html

Things you need to be aware of:

1. If phone goes to sleep your app will no longer execute, so socket will eventually timeout. You can prevent this with wake lock. This will eat devices battery tremendously - I know I wouldn't use that app.
2. If you do this constantly, even when your app is not active, then you need to use Service.
3. Activities and Services can be killed off by OS at any time, especially if they are part of an inactive app.

Take a look at AlarmManager, if you need scheduled execution of your code.

Do you need to run your code and receive data even if user does not use the app any more (i.e. app is inactive)?

To expand on Johan's answer, if the part_num column in the sub-select can contain null values then the query will break.

To correct this, add a null check...

SELECT pm.id FROM r2r.partmaster pm
WHERE pm.id NOT IN 
      (SELECT pd.part_num FROM wpsapi4.product_details pd 
                  where pd.part_num is not null)

• Sorry but I couldn't add a comment as I don't have the rep!

I'm having the same issue in Eclipse Luna in my Ubuntu VM, but I just tried to Ctrl+click on a method and it worked (even though my mouse cursor didn't change to a pointer).

I have come across this with the Hero, using what I thought was a published API. In the end, I used a test to see if the intent could be received:

private boolean isCallable(Intent intent) {
    List<ResolveInfo> list = getPackageManager().queryIntentActivities(intent, 
        PackageManager.MATCH_DEFAULT_ONLY);
    return list.size() > 0;
}

In use when I would usually just start the activity:

final Intent intent = new Intent("com.android.camera.action.CROP");
intent.setClassName("com.android.camera", "com.android.camera.CropImage");
if (isCallable(intent)) {
    // call the intent as you intended.
} else {
    // make alternative arrangements.
}

obvious: If you go down this route - using non-public APIs - you must absolutely provide a fallback which you know definitely works. It doesn't have to be perfect, it can be a Toast saying that this is unsupported for this handset/device, but you should avoid an uncaught exception. end obvious.

I find the Open Intents Registry of Intents Protocols quite useful, but I haven't found the equivalent of a TCK type list of intents which absolutely must be supported, and examples of what apps do different handsets.

You can use fs.promises available natively since Node v11.0.0

import fs from 'fs';

const readFile = async filePath => {
  try {
    const data = await fs.promises.readFile(filePath, 'utf8')
    return data
  }
  catch(err) {
    console.log(err)
  }
}

What he said. You can handle the exceptions however you like, but Thread.sleep(miliseconds); is the best route to take.

public static void main(String[] args) throws InterruptedException {

Make the value a list, e.g.

a["abc"] = [1, 2, "bob"]

UPDATE:

There are a couple of ways to add values to key, and to create a list if one isn't already there. I'll show one such method in little steps.

key = "somekey"
a.setdefault(key, [])
a[key].append(1)

Results:

>>> a
{'somekey': [1]}

Next, try:

key = "somekey"
a.setdefault(key, [])
a[key].append(2)

Results:

>>> a
{'somekey': [1, 2]}

The magic of setdefault is that it initializes the value for that key if that key is not defined, otherwise it does nothing. Now, noting that setdefault returns the key you can combine these into a single line:

a.setdefault("somekey",[]).append("bob")

Results:

>>> a
{'somekey': [1, 2, 'bob']}

You should look at the dict methods, in particular the get() method, and do some experiments to get comfortable with this.

Here's a neat workaround for simultaneous access:

while True:
    connection = sqlite3.connect('user.db', timeout=1)
    cursor = connection.cursor()
    try:
        cursor.execute("SELECT * FROM queue;")
        result = cursor.fetchall()
    except sqlite3.OperationalError:
        print("database locked")
    num_users = len(result)
# ...

to install php5-curl under opensuse:

sudo yast2

->software ->software management ->search for curl ->check php5-curl case and accept.

after installation you need to restart apache server

service apache2 restart

It looks like you don't have any records that match your query, so you'd want to return an empty array (or null or something) if the number of rows == 0.

Live Demo

Tested on Chrome / FF / IE11

There is a Chrome/IE annoyance which is that these browsers add <div> element for each new line. There is a post about this here and it can be fixed by setting the contenteditable element to be display:inline-block

Select some highlighted HTML and paste it here:

function onPaste(e){_x000D_
  var content;_x000D_
  e.preventDefault();_x000D_
_x000D_
  if( e.clipboardData ){_x000D_
    content = e.clipboardData.getData('text/plain');_x000D_
    document.execCommand('insertText', false, content);_x000D_
    return false;_x000D_
  }_x000D_
  else if( window.clipboardData ){_x000D_
    content = window.clipboardData.getData('Text');_x000D_
    if (window.getSelection)_x000D_
      window.getSelection().getRangeAt(0).insertNode( document.createTextNode(content) );_x000D_
  }_x000D_
}_x000D_
_x000D_
_x000D_
/////// EVENT BINDING /////////_x000D_

The command has to be entered in the directory of the repository. The error is complaining that your current directory isn't a git repo

1. Are you in the right directory? Does typing ls show the right files?
2. Have you initialized the repository yet? Typed git init? (git-init documentation)

Either of those would cause your error.

As Get-Date returns a DateTime object you are able to compare them directly. An example:

(get-date 2010-01-02) -lt (get-date 2010-01-01)

will return false.

If statement is used for checking just one condition quickly. When you have multiple options, use <xsl:choose> as illustrated below:

   <xsl:choose>
     <xsl:when test="$CreatedDate > $IDAppendedDate">
       <h2>mooooooooooooo</h2>
     </xsl:when>
     <xsl:otherwise>
      <h2>dooooooooooooo</h2>
     </xsl:otherwise>
   </xsl:choose>

Also, you can use multiple <xsl:when> tags to express If .. Else If or Switch patterns as illustrated below:

   <xsl:choose>
     <xsl:when test="$CreatedDate > $IDAppendedDate">
       <h2>mooooooooooooo</h2>
     </xsl:when>
     <xsl:when test="$CreatedDate = $IDAppendedDate">
       <h2>booooooooooooo</h2>
     </xsl:when>
     <xsl:otherwise>
      <h2>dooooooooooooo</h2>
     </xsl:otherwise>
   </xsl:choose>

The previous example would be equivalent to the pseudocode below:

   if ($CreatedDate > $IDAppendedDate)
   {
       output: <h2>mooooooooooooo</h2>
   }
   else if ($CreatedDate = $IDAppendedDate)
   {
       output: <h2>booooooooooooo</h2>
   }
   else
   {
       output: <h2>dooooooooooooo</h2>
   }

The answer already posted will work. If you want to use the jQuery :not you can do this:

if ($(this).is(':not(:checked)'))

or

if ($(this).attr('checked') == false)

You don't feel bad about using 'non post-back controls' anymore - and figuring how to smush them into a traditional asp.net environment.

This means that modern (free to use) javascript controls such this or this or this can all be used without that trying to fit a round peg in a square hole feel.

If the variant is empty then an error will be thrown. The bullet-proof code is the following:

Public Function GetLength(a As Variant) As Integer
   If IsEmpty(a) Then
      GetLength = 0
   Else
      GetLength = UBound(a) - LBound(a) + 1
   End If
End Function

You can set the line-height in pixels instead of percentage. Is that what you mean?

My 2 pennies:-

 collection.Count(v => (v.PropertyToUpdate = newValue) == null);

You can use AddHandler to add a handler for any event.

For example, this might be:

AddHandler theButton.Click, AddressOf Me.theButton_Click

For recent SQL:

select * from v$sql

For history:

select * from dba_hist_sqltext

the root parent have to be in pixels if you want to work freely with percents,

<body style="margin: 0px; width: 1886px; height: 939px;">
<div id="containerA" class="containerA" style="height:65%;width:100%;">
    <div id="containerAinnerDiv" style="position: relative; background-color: aqua;width:70%;height: 80%;left:15%;top:10%;">
       <div style="height: 100%;width: 50%;float: left;"></div>
       <div style="height: 100%;width: 28%;float:left">
            <img src="img/justimage.png" style="max-width:100%;max-height:100%;">
       </div>
       <div style="height: 100%;width: 22%;float: left;"></div>
    </div>
</div>
</body>

The 'file' protocol is not a network protocol. Therefore file://192.168.1.57/~User/2ndFile.html simply does not make much sense.

Question is how you load the first file. Is that really done using a web server? Does not really sound like. If it is, then why not use the same protocol, most likely http? You cannot expect to simply switch the protocol and use two different protocols the same way...

I suspect the first file is really loaded using the apache server at all, but simply by opening the file? href="2ndFile.html" simply works because it uses a "relative url". This makes the browser use the same protocol and path as where he got the first (current) file from.

I've created my own formatting utility. Which is extremely fast at processing the formatting along with giving you many features :)

It supports:

• Comma Formatting E.g. 1234567 becomes 1,234,567.
• Prefixing with "Thousand(K),Million(M),Billion(B),Trillion(T)".
• Precision of 0 through 15.
• Precision re-sizing (Means if you want 6 digit precision, but only have 3 available digits it forces it to 3).
• Prefix lowering (Means if the prefix you choose is too large it lowers it to a more suitable prefix).

The code can be found here. You call it like this:

public static void main(String[])
{
   int settings = ValueFormat.COMMAS | ValueFormat.PRECISION(2) | ValueFormat.MILLIONS;
   String formatted = ValueFormat.format(1234567, settings);
}

I should also point out this doesn't handle decimal support, but is very useful for integer values. The above example would show "1.23M" as the output. I could probably add decimal support maybe, but didn't see too much use for it since then I might as well merge this into a BigInteger type of class that handles compressed char[] arrays for math computations.

Dim and Private work the same, though the common convention is to use Private at the module level, and Dim at the Sub/Function level. Public and Global are nearly identical in their function, however Global can only be used in standard modules, whereas Public can be used in all contexts (modules, classes, controls, forms etc.) Global comes from older versions of VB and was likely kept for backwards compatibility, but has been wholly superseded by Public.

Just to help out anyone who has landed on this page after updating VS2015 to update 2 and trying to manage packages on a website, receiving the "NuGet configuration file is invalid" error, this is a known and acknowledged issue:

https://connect.microsoft.com/VisualStudio/feedback/details/2698136/nuget-configuration-is-invalid-manage-nuget-packages-for-solution-disabled

I got mine working again by installing package manager 3.4.4 (beta) from http://dist.nuget.org/index.html

They do also state update 3 for Visual Studio will also contain a fix

Profile pictures are scaled down to 125x125 on the facebook sever when they're uploaded, so as far as I know you can't get pictures bigger than that. How big is the picture you're getting?

I had added bootstrap to my project via bower, then I imported the bootstrap.min.js file and after the modal.js file. (The button that opens the modal is inside a form). I just remove the import for modal.js and it works for me.

If you are directly working with matplotlib's pyplot (plt) and if you are more familiar with the new-style format string, you can try this:

from matplotlib.ticker import StrMethodFormatter
plt.gca().yaxis.set_major_formatter(StrMethodFormatter('{x:,.0f}')) # No decimal places
plt.gca().yaxis.set_major_formatter(StrMethodFormatter('{x:,.2f}')) # 2 decimal places

From the documentation:

class matplotlib.ticker.StrMethodFormatter(fmt)

Use a new-style format string (as used by str.format()) to format the tick.

The field used for the value must be labeled x and the field used for the position must be labeled pos.

You can do the same with .ix, like this:

In [1]: df = pd.DataFrame(np.random.randn(5,4), columns=list('abcd'))

In [2]: df
Out[2]: 
          a         b         c         d
0 -0.323772  0.839542  0.173414 -1.341793
1 -1.001287  0.676910  0.465536  0.229544
2  0.963484 -0.905302 -0.435821  1.934512
3  0.266113 -0.034305 -0.110272 -0.720599
4 -0.522134 -0.913792  1.862832  0.314315

In [3]: df.ix[df.a>0, ['b','c']] = 0

In [4]: df
Out[4]: 
          a         b         c         d
0 -0.323772  0.839542  0.173414 -1.341793
1 -1.001287  0.676910  0.465536  0.229544
2  0.963484  0.000000  0.000000  1.934512
3  0.266113  0.000000  0.000000 -0.720599
4 -0.522134 -0.913792  1.862832  0.314315

EDIT

After the extra information, the following will return all columns - where some condition is met - with halved values:

>> condition = df.a > 0
>> df[condition][[i for i in df.columns.values if i not in ['a']]].apply(lambda x: x/2)

I hope this helps!

Guava Math library has a method specially designed for converting a double to a long:

long DoubleMath.roundToLong(double x, RoundingMode mode)

You can use java.math.RoundingMode to specify the rounding behavior.

To fetch only current date excluding time stamp:

in lower versions, looks like hive CURRENT_DATE is not available, hence you can use (it worked for me on Hive 0.14)

select TO_DATE(FROM_UNIXTIME(UNIX_TIMESTAMP()));

In higher versions say hive 2.0, you can use :

select CURRENT_DATE;

I have tested it (Chrome) and it working for me( both [^] and [^\0]), by changing the dot (.) by either [^\0] or [^] , because dot doesn't match line break (See here: http://www.regular-expressions.info/dot.html).

var ss= "<pre>aaaa\nbbb\nccc</pre>ddd";_x000D_
var arr= ss.match( /<pre[^\0]*?<\/pre>/gm );_x000D_
alert(arr);     //Working

It can be done at easily like as:

     <a id="send-thoughts" href="">Click</a>
     <textarea id="message"></textarea>

        $("a#send-thoughts").click(function() {
            var thought = $("#message").val();
            alert(thought);
        });

You may take a look at this post. The code might look like this:

var actualDivToBeUpdated = document.getElementById('test');
var div = document.createElement('div');
div.innerHTML = '<script type="text/javascript">alert("test");<\/script>';
var children = div.childNodes;
actualDivToBeUpdated.innerHTML = '';
for(var i = 0; i < children.length; i++) {
    actualDivToBeUpdated.appendChild(children[i]);
}

NSDate and the timeIntervalSince* methods will return a NSTimeInterval which is a double with sub-millisecond accuracy. NSTimeInterval is in seconds, but it uses the double to give you greater precision.

In order to calculate millisecond time accuracy, you can do:

// Get a current time for where you want to start measuring from
NSDate *date = [NSDate date];

// do work...

// Find elapsed time and convert to milliseconds
// Use (-) modifier to conversion since receiver is earlier than now
double timePassed_ms = [date timeIntervalSinceNow] * -1000.0;

Documentation on timeIntervalSinceNow.

There are many other ways to calculate this interval using NSDate, and I would recommend looking at the class documentation for NSDate which is found in NSDate Class Reference.

I have met the same problem. My project is running on the local server. I checked my php code.

$db = mysqli_connect('localhost', 'root', 'root', 'smart');

I use localhost to connect to my local database. That maybe the cause of the problem which you're describing. You can modify your HOSTS file. Add the line

127.0.0.1 localhost.

TL;DR

SELECT json_agg(t) FROM t

for a JSON array of objects, and

SELECT
    json_build_object(
        'a', json_agg(t.a),
        'b', json_agg(t.b)
    )
FROM t

for a JSON object of arrays.

List of objects

This section describes how to generate a JSON array of objects, with each row being converted to a single object. The result looks like this:

[{"a":1,"b":"value1"},{"a":2,"b":"value2"},{"a":3,"b":"value3"}]

9.3 and up

The json_agg function produces this result out of the box. It automatically figures out how to convert its input into JSON and aggregates it into an array.

SELECT json_agg(t) FROM t

There is no jsonb (introduced in 9.4) version of json_agg. You can either aggregate the rows into an array and then convert them:

SELECT to_jsonb(array_agg(t)) FROM t

or combine json_agg with a cast:

SELECT json_agg(t)::jsonb FROM t

My testing suggests that aggregating them into an array first is a little faster. I suspect that this is because the cast has to parse the entire JSON result.

9.2

9.2 does not have the json_agg or to_json functions, so you need to use the older array_to_json:

SELECT array_to_json(array_agg(t)) FROM t

You can optionally include a row_to_json call in the query:

SELECT array_to_json(array_agg(row_to_json(t))) FROM t

This converts each row to a JSON object, aggregates the JSON objects as an array, and then converts the array to a JSON array.

I wasn't able to discern any significant performance difference between the two.

Object of lists

This section describes how to generate a JSON object, with each key being a column in the table and each value being an array of the values of the column. It's the result that looks like this:

{"a":[1,2,3], "b":["value1","value2","value3"]}

9.5 and up

We can leverage the json_build_object function:

SELECT
    json_build_object(
        'a', json_agg(t.a),
        'b', json_agg(t.b)
    )
FROM t

You can also aggregate the columns, creating a single row, and then convert that into an object:

SELECT to_json(r)
FROM (
    SELECT
        json_agg(t.a) AS a,
        json_agg(t.b) AS b
    FROM t
) r

Note that aliasing the arrays is absolutely required to ensure that the object has the desired names.

Which one is clearer is a matter of opinion. If using the json_build_object function, I highly recommend putting one key/value pair on a line to improve readability.

You could also use array_agg in place of json_agg, but my testing indicates that json_agg is slightly faster.

There is no jsonb version of the json_build_object function. You can aggregate into a single row and convert:

SELECT to_jsonb(r)
FROM (
    SELECT
        array_agg(t.a) AS a,
        array_agg(t.b) AS b
    FROM t
) r

Unlike the other queries for this kind of result, array_agg seems to be a little faster when using to_jsonb. I suspect this is due to overhead parsing and validating the JSON result of json_agg.

Or you can use an explicit cast:

SELECT
    json_build_object(
        'a', json_agg(t.a),
        'b', json_agg(t.b)
    )::jsonb
FROM t

The to_jsonb version allows you to avoid the cast and is faster, according to my testing; again, I suspect this is due to overhead of parsing and validating the result.

9.4 and 9.3

The json_build_object function was new to 9.5, so you have to aggregate and convert to an object in previous versions:

SELECT to_json(r)
FROM (
    SELECT
        json_agg(t.a) AS a,
        json_agg(t.b) AS b
    FROM t
) r

or

SELECT to_jsonb(r)
FROM (
    SELECT
        array_agg(t.a) AS a,
        array_agg(t.b) AS b
    FROM t
) r

depending on whether you want json or jsonb.

(9.3 does not have jsonb.)

9.2

In 9.2, not even to_json exists. You must use row_to_json:

SELECT row_to_json(r)
FROM (
    SELECT
        array_agg(t.a) AS a,
        array_agg(t.b) AS b
    FROM t
) r

Documentation

Find the documentation for the JSON functions in JSON functions.

json_agg is on the aggregate functions page.

Design

If performance is important, ensure you benchmark your queries against your own schema and data, rather than trust my testing.

Whether it's a good design or not really depends on your specific application. In terms of maintainability, I don't see any particular problem. It simplifies your app code and means there's less to maintain in that portion of the app. If PG can give you exactly the result you need out of the box, the only reason I can think of to not use it would be performance considerations. Don't reinvent the wheel and all.

Nulls

Aggregate functions typically give back NULL when they operate over zero rows. If this is a possibility, you might want to use COALESCE to avoid them. A couple of examples:

SELECT COALESCE(json_agg(t), '[]'::json) FROM t

Or

SELECT to_jsonb(COALESCE(array_agg(t), ARRAY[]::t[])) FROM t

I'f you're suppsed to be able to use it, then 3rd-party library should have a *.lib file as well as a *.dll file. You simply need to add the *.lib to the list of input file in your project's 'Linker' options.

This *.lib file isn't necessarily a 'static' library (which contains code): instead a *.lib can be just a file that links your executable to the DLL.

HTML are markup languages, basically they are set of tags like <html>, <body>, which is used to present a website using css, and javascript as a whole. All these, happen in the clients system or the user you will be browsing the website.

Now, Connecting to a database, happens on whole another level. It happens on server, which is where the website is hosted.

So, in order to connect to the database and perform various data related actions, you have to use server-side scripts, like php, jsp, asp.net etc.

Now, lets see a snippet of connection using MYSQLi Extension of PHP

$db = mysqli_connect('hostname','username','password','databasename');

This single line code, is enough to get you started, you can mix such code, combined with HTML tags to create a HTML page, which is show data based pages. For example:

<?php
    $db = mysqli_connect('hostname','username','password','databasename');
?>
<html>
    <body>
          <?php
                $query = "SELECT * FROM `mytable`;";
                $result = mysqli_query($db, $query);
                while($row = mysqli_fetch_assoc($result)) {
                      // Display your datas on the page
                }
          ?>
    </body>
</html>

In order to insert new data into the database, you can use phpMyAdmin or write a INSERT query and execute them.

Leave off the quotes

$cmd &
$othercmd &

eg:

nicholas@nick-win7 /tmp
$ cat test
#!/bin/bash

cmd="ls -la"

TL;DR For conforming browsers, yes; but there are no conforming browsers, so no.

According to the HTML 4 specification, <!------> hello--> is a perfectly valid comment. However, I've not found a browser which implements this correctly (i.e. per the specification) due to developers not knowing, nor following, the standards (as digitaldreamer pointed out).

You can find the definition of a comment for HTML4 on the w3c's website: http://www.w3.org/TR/html4/intro/sgmltut.html#h-3.2.4

Another thing that many browsers get wrong is that -- > closes a comment just like -->.

I posted an answer to this already when someone else asked the same question (see How to bring back "Browser mode" in IE11?).

Read my answer there for a fuller explaination, but in short:

• They removed it deliberately, because compat mode is not actually really very good for testing compatibility.

• If you really want to test for compatibility with any given version of IE, you need to test in a real copy of that IE version. MS provide free VMs on http://modern.ie/ for you to use for this purpose.

• The only way to get compat mode in IE11 is to set the X-UA-Compatible header. When you have this and the site defaults to compat mode, you will be able to set the mode in dev tools, but only between edge or the specified compat mode; other modes will still not be available.

Take a look at the keypress function.

I believe the enter key is 13 so you would want something like:

$('#searchButton').keypress(function(e){
    if(e.which == 13){  //Enter is key 13
        //Do something
    }
});

As per your question vertical listing have a scrollbar effect.

In Swift 4.2 the notification names have moved to a different namespace. So now it's

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    addKeyboardListeners()
}


override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)
    NotificationCenter.default.removeObserver(self)
}


func addKeyboardListeners() {
    NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillHide), name: UIResponder.keyboardWillHideNotification, object: nil)
    NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillShow), name: UIResponder.keyboardWillShowNotification, object: nil)
}

@objc private extension WhateverTheClassNameIs {

    func keyboardWillShow(_ notification: Notification) {
        // Do something here.
    }

    func keyboardWillHide(_ notification: Notification) {
        // Do something here.
    }
}

Here is another way to convert Drawable resource into Bitmap in android:

Drawable drawable = getResources().getDrawable(R.drawable.input);
Bitmap bitmap = ((BitmapDrawable)drawable).getBitmap();

\b matches a word-boundary. \B matches non-word-boundaries, and is equivalent to [^\b](?!\b) _{^{(thanks to @Alan Moore for the correction!)}}. Both are zero-width.

See http://www.regular-expressions.info/wordboundaries.html for details. The site is extremely useful for many basic regex questions.

Compatibility Guide for JDK 8 says that in Java 8 the command line flag MaxPermSize has been removed. The reason is that the permanent generation was removed from the hotspot heap and was moved to native memory. So in order to remove this message edit MAVEN_OPTS Environment User Variable:

Java 7

MAVEN_OPTS -Xmx512m -XX:MaxPermSize=128m

Java 8

MAVEN_OPTS -Xmx512m

Though this question was asked a few years ago, a jQuery plugin isn't required anymore provided the date value in question is a string with format mm/dd/yyyy (like when using a date-picker);

var birthdateVal = $('#birthdate').val();
//birthdateVal: 11/8/2014

var birthdate = new Date(birthdateVal);
//birthdate: Sat Nov 08 2014 00:00:00 GMT-0500 (Eastern Standard Time)

Pandas concat vs append vs join vs merge

• Concat gives the flexibility to join based on the axis( all rows or all columns)

• Append is the specific case(axis=0, join='outer') of concat

• Join is based on the indexes (set by set_index) on how variable =['left','right','inner','couter']

• Merge is based on any particular column each of the two dataframes, this columns are variables on like 'left_on', 'right_on', 'on'

Its just to save a byte of data when we do javascript minification.

consider the below anonymous function

function (){}

To make the above as self invoking function we will generally change the above code as

(function (){}())

Now we added two extra characters (,) apart from adding () at the end of the function which necessary to call the function. In the process of minification we generally focus to reduce the file size. So we can also write the above function as

!function (){}()

Still both are self invoking functions and we save a byte as well. Instead of 2 characters (,) we just used one character !

I removed the old web library such that are spring framework libraries. And build a new path of the libraries. Then it works.

I also had this issue where some parameterized queries or sp's would give me a SqlException (mostly the string or binary data would be truncated), and the statements where hard to debug (As far as i know there currently is no sql-profiler support for SQL Azure)

I see a lot of simular code in reactions here. I ended up putting my solution in a Sql-Library project for future use.

The generator is available here: https://github.com/jeroenpot/SqlHelper/blob/master/Source/Mirabeau.MsSql.Library/SqlGenerator.cs

It supports both CommandType.Text and CommandType.StoredProcedure

And if you install the nuget-package you can generate it with this statement:

SqlDebugHelper.CreateExecutableSqlStatement(sql, parameters);

I've made a little modification to split files based on size of each part.

##############################################################################
#.SYNOPSIS
# Breaks a text file into multiple text files in a destination, where each
# file contains a maximum number of lines.
#
#.DESCRIPTION
# When working with files that have a header, it is often desirable to have
# the header information repeated in all of the split files. Split-File
# supports this functionality with the -rc (RepeatCount) parameter.
#
#.PARAMETER Path
# Specifies the path to an item. Wildcards are permitted.
#
#.PARAMETER LiteralPath
# Specifies the path to an item. Unlike Path, the value of LiteralPath is
# used exactly as it is typed. No characters are interpreted as wildcards.
# If the path includes escape characters, enclose it in single quotation marks.
# Single quotation marks tell Windows PowerShell not to interpret any
# characters as escape sequences.
#
#.PARAMETER Destination
# (Or -d) The location in which to place the chunked output files.
#
#.PARAMETER Size
# (Or -s) The maximum size of each file. Size must be expressed in MB.
#
#.PARAMETER RepeatCount
# (Or -rc) Specifies the number of "header" lines from the input file that will
# be repeated in each output file. Typically this is 0 or 1 but it can be any
# number of lines.
#
#.EXAMPLE
# Split-File bigfile.csv -s 20 -rc 1
#
#.LINK 
# Out-TempFile

Combining previous answers:

$('input[name="cols"]').filter("[value='Site']").click();

When we does not want to own the object:

Ex:

class A
{
    shared_ptr<int> sPtr1;
    weak_ptr<int> wPtr1;
}

In the above class wPtr1 does not own the resource pointed by wPtr1. If the resource is got deleted then wPtr1 is expired.

To avoid circular dependency:

shard_ptr<A> <----| shared_ptr<B> <------
    ^             |          ^          |
    |             |          |          |
    |             |          |          |
    |             |          |          |
    |             |          |          |
class A           |     class B         |
    |             |          |          |
    |             ------------          |
    |                                   |
    -------------------------------------

Now if we make the shared_ptr of the class B and A, the use_count of the both pointer is two.

When the shared_ptr goes out od scope the count still remains 1 and hence the A and B object does not gets deleted.

class B;

class A
{
    shared_ptr<B> sP1; // use weak_ptr instead to avoid CD

public:
    A() {  cout << "A()" << endl; }
    ~A() { cout << "~A()" << endl; }

    void setShared(shared_ptr<B>& p)
    {
        sP1 = p;
    }
};

class B
{
    shared_ptr<A> sP1;

public:
    B() {  cout << "B()" << endl; }
    ~B() { cout << "~B()" << endl; }

    void setShared(shared_ptr<A>& p)
    {
        sP1 = p;
    }
};

int main()
{
    shared_ptr<A> aPtr(new A);
    shared_ptr<B> bPtr(new B);

    aPtr->setShared(bPtr);
    bPtr->setShared(aPtr);

    return 0;  
}

output:

A()
B()

As we can see from the output that A and B pointer are never deleted and hence memory leak.

To avoid such issue just use weak_ptr in class A instead of shared_ptr which makes more sense.

My fix was to remove the double quotes that I had enclosed the JAVA_HOME path in.

Instead of declaring JAVA_HOME as "C\Program Files..."

I removed the " and declared JAVA_HOME as C\Program Files...
