There is simple answer in the official guide:

What does it not do?

It does not cause a full page reload when the browser URL is changed. To reload the page after changing the URL, use the lower-level API, $window.location.href.

In my experience, it has expired at the end of that month. That is based on the fact that I can use it during that month, and that month is when my bank sends a new one.

Note that it is now possible to use some of C++11 std::thread in the win32 threading mode. These header-only adapters worked out of the box for me: https://github.com/meganz/mingw-std-threads

From the revision history it looks like there is some recent attempt to make this a part of the mingw64 runtime.

awk ' BEGIN { print "Hello, world" } ' > test.txt

I had the same problem. Adding new rows to WPF DataGrid requires a trick. DataGrid relies on property fields of an item object. ExpandoObject enables to add new properties dynamically. The code below explains how to do it:

// using System.Dynamic;

DataGrid dataGrid;

string[] labels = new string[] { "Column 0", "Column 1", "Column 2" };

foreach (string label in labels)
{
    DataGridTextColumn column = new DataGridTextColumn();
    column.Header = label;
    column.Binding = new Binding(label.Replace(' ', '_'));

    dataGrid.Columns.Add(column);
}

int[] values = new int[] { 0, 1, 2 };

dynamic row = new ExpandoObject();

for (int i = 0; i < labels.Length; i++)
    ((IDictionary<String, Object>)row)[labels[i].Replace(' ', '_')] = values[i];

dataGrid.Items.Add(row);

//edit:

Note that this is not the way how the component should be used, however, it simplifies a lot if you have only programmatically generated data (eg. in my case: a sequence of features and neural network output).

Try this puglin simpleUpload, no need form

Html:

<input type="file" name="arquivo" id="simpleUpload" multiple >
<button type="button" id="enviar">Enviar</button>

Javascript:

$('#simpleUpload').simpleUpload({
  url: 'upload.php',
  trigger: '#enviar',
  success: function(data){
    alert('Envio com sucesso');

  }
});

Although JS implementations might keep track of such a value internally, there's no standard way to get it.

In the past, Mozilla's Javascript variant exposed the non-standard __count__, but it has been removed with version 1.8.5.

For cross-browser scripting you're stuck with explicitly iterating over the properties and checking hasOwnProperty():

function countProperties(obj) {
    var count = 0;

    for(var prop in obj) {
        if(obj.hasOwnProperty(prop))
            ++count;
    }

    return count;
}

In case of ECMAScript 5 capable implementations, this can also be written as (Kudos to Avi Flax)

function countProperties(obj) {
    return Object.keys(obj).length;
}

Keep in mind that you'll also miss properties which aren't enumerable (eg an array's length).

If you're using a framework like jQuery, Prototype, Mootools, $whatever-the-newest-hype, check if they come with their own collections API, which might be a better solution to your problem than using native JS objects.

You don't want to do this. It is invalid HTML to have more than one element with the same id. Browsers won't treat that well, and you will have undefined behavior, meaning you have no idea what the browser will give you when you select an element by that id, it could be unpredictable.

You should be using a class, or just iterating through the inputs and keeping track of an index.

Try something like this:

var div2 = document.getElementById('div2');
for(i = j = 0; i < div2.childNodes.length; i++)
    if(div2.childNodes[i].nodeName == 'INPUT'){
        j++;
        var input = div2.childNodes[i];
        alert('This is edit'+j+': '+input);
    }

use rgba (rgb with alpha transparency):

border: 10px solid rgba(0,0,0,0.5); // 0.5 means 50% of opacity

The alpha transparency variate between 0 (0% opacity = 100% transparent) and 1 (100 opacity = 0% transparent)

To Add Custom View to SuperView use:

self.view.addSubview(myView)

To Remove Custom View from Superview use:

self.view.willRemoveSubview(myView)

To make this work in Chrome and Safari, you would have to do it like this

window.onbeforeunload = function(e) {
    return "Sure you want to leave?";
};

Jenkins 2.9

1. Jenkins > New Item

   

2. Enter an item name - E.g. "MY_CLONE"

   

3. Specify the source (Copy from) job > OK

   When you start typing the name, the existing values will be found. Notice that this is case sensitive.

   

4. Click on Save if you want to keep the default values.

5. Now both jobs are available in the same location:

   

Exit code 137 (128+9) indicates that your program exited due to receiving signal 9, which is SIGKILL. This also explains the killed message. The question is, why did you receive that signal?

The most likely reason is probably that your process crossed some limit in the amount of system resources that you are allowed to use. Depending on your OS and configuration, this could mean you had too many open files, used too much filesytem space or something else. The most likely is that your program was using too much memory. Rather than risking things breaking when memory allocations started failing, the system sent a kill signal to the process that was using too much memory.

As I commented earlier, one reason you might hit a memory limit after printing finished counting is that your call to counter.items() in your final loop allocates a list that contains all the keys and values from your dictionary. If your dictionary had a lot of data, this might be a very big list. A possible solution would be to use counter.iteritems() which is a generator. Rather than returning all the items in a list, it lets you iterate over them with much less memory usage.

So, I'd suggest trying this, as your final loop:

for key, value in counter.iteritems():
    writer.writerow([key, value])

Note that in Python 3, items returns a "dictionary view" object which does not have the same overhead as Python 2's version. It replaces iteritems, so if you later upgrade Python versions, you'll end up changing the loop back to the way it was.

You want to use "multiline".

$string =~ /(START)(.+?)(END)/m;

Dynamic Values (oh no! D;)

As npup explains in his answer, a simple css rule will only target the attribute value which means that this doesn't cover the actual value of the html node.

JAVASCRIPT TO THE RESCUE!

• Ugly workaround: http://jsfiddle.net/QmvHL/

Original Answer

Yes it's very possible, using css attribute selectors you can reference input's by their value in this sort of fashion:

input[value="United States"] { color: #F90; }?

• jsFiddle example

from the reference

• [att] Match when the element sets the "att" attribute, whatever the value of the attribute.

• [att=val] Match when the element's "att" attribute value is exactly "val".

• [att~=val] Represents an element with the att attribute whose value is a white space-separated list of words, one of which is exactly "val". If "val" contains white space, it will never represent anything (since the words are separated by spaces). If "val" is the empty string, it will never represent anything either.

• [att|=val] Represents an element with the att attribute, its value either being exactly "val" or beginning with "val" immediately followed by "-" (U+002D). This is primarily intended to allow language subcode matches (e.g., the hreflang attribute on the a element in HTML) as described in BCP 47 ([BCP47]) or its successor. For lang (or xml:lang) language subcode matching, please see the :lang pseudo-class.

Command line arguments are accessible via String[] args parameter of main method.

For first argument you can check args[0]

entire code would look like

public static void main(String[] args) {
    if ("a".equals(args[0])) {
         // do something
    }
}

select to_char(sysdate, 'DD-fmMONTH-YYYY') "Date" from Dual;

The above query result will be as given below.

Here's what I always do:

ls log* | awk 'END{print NR}'

While many options above function well, I found coercion of non-target variables to chr problematic. Using ifelse and grepl within lapply resolves this off-target effect (in limited testing). Using slarky's regular expression in grepl:

set.seed(42)
x1 <- sample(c("a","b"," ", "a a", NA), 10, TRUE)
x2 <- sample(c(rnorm(length(x1),0, 1), NA), length(x1), TRUE)

df <- data.frame(x1, x2, stringsAsFactors = FALSE)

The problem of coercion to character class:

df2 <- lapply(df, function(x) gsub("^$|^ $", NA, x))
lapply(df2, class)

$x1 [1] "character"

$x2 [1] "character"

Resolution with use of ifelse:

df3 <- lapply(df, function(x) ifelse(grepl("^$|^ $", x)==TRUE, NA, x))
lapply(df3, class)

$x1 [1] "character"

$x2 [1] "numeric"

Have you tried running the code in the Page_Load() method?

protected void Page_Load(object sender, EventArgs e) 
{

         Label1.Text = "test";
        if (Request.QueryString["ID"] != null)
        {

            string test = Request.QueryString["ID"];
            Label1.Text = "Du har nu lånat filmen:" + test;
        }
}

The standard technique in plugin form would look something like this:

(function($) {
    $.fn.goTo = function() {
        $('html, body').animate({
            scrollTop: $(this).offset().top + 'px'
        }, 'fast');
        return this; // for chaining...
    }
})(jQuery);

Then you could just say $('#div_element2').goTo(); to scroll to <div id="div_element2">. Options handling and configurability is left as an exercise for the reader.

Unfortunately you're probably done with the animation and presentation already. In the hopes this answer can help future questioners, however, this blog post has a walkthrough of steps that can loop a single slide as a sort of sub-presentation.

First, click Slide Show > Set Up Show.

Put a checkmark to Loop continuously until 'Esc'.

Click Ok. Now, Click Slide Show > Custom Shows. Click New.

Select the slide you are looping, click Add. Click Ok and Close.

Click on the slide you are looping. Click Slide Show > Slide Transition. Under Advance slide, put a checkmark to Automatically After. This will allow the slide to loop automatically. Do NOT Apply to all slides.

Right click on the thumbnail of the current slide, select Hide Slide.

Now, you will need to insert a new slide just before the slide you are looping. On the new slide, insert an action button. Set the hyperlink to the custom show you have created. Put a checkmark on "Show and Return"

This has worked for me.

print '\033[1m  Your Name  \033[0m'

\033[1m is the unicode for bold in the terminal \033[0m is the unicode for end the edited text and back default text formate!!!!!

if you do not use \033[0m than all upcoming text of the terminal will become bold!!!!!!!!!

You might set location directly because it's slightly shorter. If you're trying to be terse, you can usually omit the window. too.

URL assignments to both location.href and location are defined to work in JavaScript 1.0, back in Netscape 2, and have been implemented in every browser since. So take your pick and use whichever you find clearest.

Looks like the path you gave doesn't have any bootstrap files in them.

href="~/lib/bootstrap/dist/css/bootstrap.min.css"

Make sure the files exist over there , else point the files to the correct path, which should be in your case

href="~/node_modules/bootstrap/dist/css/bootstrap.min.css"

It seems that in the debug log for Java 6 the request is send in SSLv2 format.

main, WRITE: SSLv2 client hello message, length = 110

This is not mentioned as enabled by default in Java 7.
Change the client to use SSLv3 and above to avoid such interoperability issues.

Look for differences in JSSE providers in Java 7 and Java 6

Use the following instead:

boost::function<void (int)> f2( boost::bind( &myclass::fun2, this, _1 ) );

This forwards the first parameter passed to the function object to the function using place-holders - you have to tell Boost.Bind how to handle the parameters. With your expression it would try to interpret it as a member function taking no arguments.
See e.g. here or here for common usage patterns.

Note that VC8s cl.exe regularly crashes on Boost.Bind misuses - if in doubt use a test-case with gcc and you will probably get good hints like the template parameters Bind-internals were instantiated with if you read through the output.

I was able to make this work with the

transform: scale(1.03);

Property applied on the image. For some reason, on Chrome, the other solutions provided wouldn't work if there was any relatively positioned parent element.

Check http://jsfiddle.net/ud5ya7jt/

This way the image will be slightly zoomed in by 3% and the edges will be cropped which shouldn't be a problem on a blurred image anyway. It worked well in my case because I was using a high res image as a background. Good luck!

HTML:

<input name="name" id="name" type="text" value="Name" onfocus="clearField(this);" onblur="fillField(this);"/>

JS:

function clearField(input) {
  if(input.value=="Name") { //Only clear if value is "Name"
    input.value = "";
  }
}
function fillField(input) {
    if(input.value=="") {
        input.value = "Name";
    }
}

I came across this error due to the improper closing of the statement,

@using (Html.BeginForm("DeleteSelected", "Employee", FormMethod.Post))

{

} //This curly bracket needed to be closed at the end.

In Index.cshtml view file.I didn't close the statement at the end of the program. instead, I ended up closing improperly and ran into this error.

I was sure there isn't a need of checking Controller ActionMethod code because I have returned the Controller method properly to the View. So It has to be the view that's not responding and met with similar Error.

you can add the username and password to the SOAP Header

BindingProvider prov = (BindingProvider)port;
prov.getRequestContext().put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY,

prov.getRequestContext().put(BindingProvider.PASSWORD_PROPERTY, "mypassword");
prov.getRequestContext().put(MessageContext.HTTP_REQUEST_HEADERS, headers);

This feature has been built-in into Atom editor (see: symbols-view package), but you need to generate ctags symbols file for your project ^{GH-9, GH-20}.

To do that, install ctags command (e.g. brew install ctags on macOS), then:

1. Append, link or copy ctags-config to your ~/.ctags, example on macOS:

   ln -vs "$(find /Applications/Atom.app -name ctags-config -print -quit)" ~/.ctags
   

2. Go to your project folder and run:

   cd your/project/directory
   ctags -R .
   

3. Restart Atom editor.

Alternatively you can use symbol-gen package to generate ctags symbols file for your project based on the options found in .ctags file. You can install it from Atom Package Manager by: apm install symbol-gen. Then hit CMD-Alt-G to generate tags file for your project.

After following above, you can use Go To Declaration option from the context menu.

On macOS you can use also use the following keyboard shortcuts:

• CMD-R to jump to a function/method in the current ,editor
• Alt-CMD-Down to go to declaration.

I found the solution.

As said in the EDIT of my answer, a <div> is misfunctioning in a <table>. So I wrote this code instead :

<tr id="hidden" style="display:none;">
    <td class="depot_table_left">
        <label for="sexe">Sexe</label>
    </td>
    <td>
        <select type="text" name="sexe">
            <option value="1">Sexe</option>
            <option value="2">Joueur</option>
            <option value="3">Joueuse</option>
        </select>
    </td>
</tr>

And this is working fine.

Thanks everybody ;)

You can use an array in the select() to define more columns and you can use the DB::raw() there with aliasing it to followers. Should look like this:

$query = DB::table('category_issue')
    ->select(array('issues.*', DB::raw('COUNT(issue_subscriptions.issue_id) as followers')))
    ->where('category_id', '=', 1)
    ->join('issues', 'category_issue.issue_id', '=', 'issues.id')
    ->left_join('issue_subscriptions', 'issues.id', '=', 'issue_subscriptions.issue_id')
    ->group_by('issues.id')
    ->order_by('followers', 'desc')
    ->get();

Try changing your headers to this:

$headers = "MIME-Version: 1.0" . "\r\n";
$headers .= "Content-type: text/html; charset=iso-8859-1" . "\r\n";
$headers .= "From: [email protected]" . "\r\n" .
"Reply-To: [email protected]" . "\r\n" .
"X-Mailer: PHP/" . phpversion();

For a few reasons.

• One of which is the need of a Reply-To and,

• The use of apostrophes instead of double-quotes. Those two things in my experience with forms, is usually what triggers a message ending up in the Spam box.

You could also try changing the $from to:

$from = "[email protected]";

You can use conda remove --force.

The documentation says:

--force               Forces removal of a package without removing packages
                      that depend on it. Using this option will usually
                      leave your environment in a broken and inconsistent
                      state

Try following command :

find /your/path -printf "%k %p\n" | sort -g -k 1,1 | awk '{if($1 > 500000) print $1/1024 "MB" " " $2 }' |tail -n 1 

This will print the largest file name and size and more than 500M. You can move the if($1 > 500000),and it will print the largest file in the directory.

@therefromhere's answer is the best one. However Node versions have moved ever onwards and upwards, and the versioning was complicated by the remerge of io.js. Following the steps in his answer, you will end up with Node version 0.10.25 - not the most recent version.

You should still purge any existing node/npm packages with

sudo apt-get purge nodejs npm

and then go and look at the nodesource deb install page at https://github.com/nodesource/distributions#debinstall.

All Node.js versions are listed on the above page with the Linux commands to install them. And these packages will work on both Debian and Ubuntu.

P.S. If you want to run Node v4.4 or higher on Ubuntu Precise or Debian Wheezy, you should review the information about running on older distros.

P.P.S. If your apt-get is failing, the script will not complete (Google references were failing my apt-get update). You should see messages about the NodeSource signing key being added to your keyring and a final message instructing you to Run 'apt-get install nodejs' to install Node.js.

P.P.P.S. npm is installed with node. Once installed, you can update to the latest npm with sudo npm install npm -g

Use the getTime method to get the time in total milliseconds since 1970-01-01, and subtract those:

var time = new Date().getTime() - new Date("2013-02-20T12:01:04.753Z").getTime();

Alternatively, you can use requests.Session and observe cookies before and after a request:

>>> import requests
>>> session = requests.Session()
>>> print(session.cookies.get_dict())
{}
>>> response = session.get('http://google.com')
>>> print(session.cookies.get_dict())

I encountered this problem with the Android SDK sdkmanager. For me this solution worked:

1. Go to /usr/lib/jvm/java-8-oracle/jre/lib/security/
2. Replace cacert with cacert.original

The cacert file was a tiny one (22B). I have installed oracle-java8-installer from ppa:webupd8team/java (according to this manual: https://docs.nativescript.org/start/ns-setup-linux).

When you get the error message, you have the option to click on "Debug": this will lead you to the line where the error occurred. The Dark Canuck seems to be right, and I guess the error occurs on the line:

Sheets("Sheet1").protect Password:="btfd"

because most probably the "Sheet1" does not exist. However, if you say "It works fine, but when I save the file I get the message: run-time error '9': subscription out of range" it makes me think the error occurs on the second line:

ActiveWorkbook.Save

Could you please check this by pressing the Debug button first? And most important, as Gordon Bell says, why are you using a macro to protect a workbook?

Javadocs don't offer any special tools for external links, so you should just use standard html:

Here all solutions are based on Class Component, but i guess most of the people who learned React recently (like me), at this time using functional Component. So here is the solution based on functional component.

Using useRef hooks of ReactJs and inputRef property of TextField.

    import React, { useRef, Component } from 'react'
    import { TextField, Button } from '@material-ui/core'
    import SendIcon from '@material-ui/icons/Send'

    export default function MultilineTextFields() {
    const valueRef = useRef('') //creating a refernce for TextField Component

    const sendValue = () => {
        return console.log(valueRef.current.value) //on clicking button accesing current value of TextField and outputing it to console 
    }

    return (
        <form noValidate autoComplete='off'>
        <div>
            <TextField
            id='outlined-textarea'
            label='Content'
            placeholder='Write your thoughts'
            multiline
            variant='outlined'

This exception could point to the LINQ parameter that is named source:

 System.Linq.Enumerable.Select[TSource,TResult](IEnumerable`1 source, Func`2 selector)

As the source parameter in your LINQ query (var nCounts = from sale in sal) is 'sal', I suppose the list named 'sal' might be null.

I try to @Chumillas's answer and @chhameed's answer, but it not work,because the sql is wrong.So I found new approach,like this:

• Insert echo $sql; flush(); exit; into before return $sql; _compile_select function of DB_active_rec.php

Just use:

 param.AddWithValue("@Date_Of_Birth",DOB);

That will take care of all your problems.

You need to make the call to setDate separately from the initialization call. So to create the datepicker and set the date in one go:

$("#mydate").datepicker().datepicker("setDate", new Date());

Why it is like this I do not know. If anyone did, that would be interesting information.

Using pygame on any platform

The advantage of using pygame is that it can be made to work on any OS platform. Below example code is for GNU/Linux though.

First install the pygame module for python3 as explained in detail here.

$ sudo pip3 install pygame

The pygame module can play .wav and .ogg files from any file location. Here is an example:

#!/usr/bin/env python3
import pygame
pygame.mixer.init()
sound = pygame.mixer.Sound('/usr/share/sounds/freedesktop/stereo/phone-incoming-call.oga')
sound.play()

The problem here is that you are including commands.c in commands.h before the function prototype. Therefore, the C pre-processor inserts the content of commands.c into commands.h before the function prototype. commands.c contains the function definition. As a result, the function definition ends up before than the function declaration causing the error.

The content of commands.h after the pre-processor phase looks like this:

#ifndef COMMANDS_H_
#define COMMANDS_H_

// function definition
void f123(){

}

// function declaration
void f123();

#endif /* COMMANDS_H_ */

This is an error because you can't declare a function after its definition in C. If you swapped #include "commands.c" and the function declaration the error shouldn't happen because, now, the function prototype comes before the function declaration.

However, including a .c file is a bad practice and should be avoided. A better solution for this problem would be to include commands.h in commands.c and link the compiled version of command to the main file. For example:

commands.h

#ifndef COMMANDS_H_
#define COMMANDS_H_

void f123(); // function declaration

#endif

commands.c

#include "commands.h"

void f123(){} // function definition

There's also str_pad

<?php
$input = "Alien";
echo str_pad($input, 10);                      // produces "Alien     "
echo str_pad($input, 10, "-=", STR_PAD_LEFT);  // produces "-=-=-Alien"
echo str_pad($input, 10, "_", STR_PAD_BOTH);   // produces "__Alien___"
echo str_pad($input, 6 , "___");               // produces "Alien_"
?>

Use GREATEST()

E.g.:

SELECT GREATEST(2,1);

Note: Whenever if any single value contains null at that time this function always returns null (Thanks to user @sanghavi7)

Why you cant use default CSS classes and add some your style?

.slick-next {
  /*my style*/
  background: url(my-image.png);
}

and

.slick-prev {
  /*my style*/
  background: url(my-image.png);
}

Are you used simple background css property?

in example: http://jsfiddle.net/BNvke/1/

You can use Font Awesome too. Don't forget about CSS pseudo elements.

And don't forget jQuery, you can replace elements, add classes, etc.

Update: Using DateTimeFormat, introduced in java 8:

The idea is to define two formats: one for the input format, and one for the output format. Parse with the input formatter, then format with the output formatter.

Your input format looks quite standard, except the trailing Z. Anyway, let's deal with this: "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'". The trailing 'Z' is the interesting part. Usually there's time zone data here, like -0700. So the pattern would be ...Z, i.e. without apostrophes.

The output format is way more simple: "dd-MM-yyyy". Mind the small y -s.

Here is the example code:

DateTimeFormatter inputFormatter = DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'", Locale.ENGLISH);
DateTimeFormatter outputFormatter = DateTimeFormatter.ofPattern("dd-MM-yyy", Locale.ENGLISH);
LocalDate date = LocalDate.parse("2018-04-10T04:00:00.000Z", inputFormatter);
String formattedDate = outputFormatter.format(date);
System.out.println(formattedDate); // prints 10-04-2018

Original answer - with old API SimpleDateFormat

SimpleDateFormat inputFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
SimpleDateFormat outputFormat = new SimpleDateFormat("dd-MM-yyyy");
Date date = inputFormat.parse("2018-04-10T04:00:00.000Z");
String formattedDate = outputFormat.format(date);
System.out.println(formattedDate); // prints 10-04-2018

I had to:

• Create a local administrator
• Add a Microsoft Loopback adapter
• Reference the location as \\127.0.0.1\SSRSFileShare

This is a warning for usual. You can either disable it by

#pragma warning(disable:4996)

or simply use fopen_s like Microsoft has intended.

But be sure to use the pragma before other headers.

1. This is not done in PHP. It's part of the <head> tags in a HTML page.
2. That icon is called a favicon. According to Wikipedia:

   A favicon (short for favorites icon), also known as a shortcut icon, website icon, URL icon, or bookmark icon is a 16×16 or 32×32 pixel square icon associated with a particular website or webpage.

3. Adding it is easy. Just add an .ico image file that is either 16x16 pixels or 32x32 pixels. Then, in the web pages, add <link rel="shortcut icon" href="favicon.ico" type="image/x-icon"> to the <head> element.
4. You can easily generate favicons here.

You can also use the Get-Counter cmdlet (PowerShell 2.0):

Get-Counter '\Memory\Available MBytes'
Get-Counter '\Processor(_Total)\% Processor Time'

To get a list of memory counters:

Get-Counter -ListSet *memory* | Select-Object -ExpandProperty  Counter

It indicates that you do not have a newline (usually '\n', aka CR or CRLF) at the end of file.

That is, simply speaking, the last byte (or bytes if you're on Windows) in the file is not a newline.

The message is displayed because otherwise there is no way to tell the difference between a file where there is a newline at the end and one where is not. Diff has to output a newline anyway, or the result would be harder to read or process automatically.

Note that it is a good style to always put the newline as a last character if it is allowed by the file format. Furthermore, for example, for C and C++ header files it is required by the language standard.

This isn't about MS and what they want. They have created an *open system for others to plug-in 'providers' - postgres and sqlite have it - mysql is just laggin... but, good news for those interested, i too was looking for this and found that the MySql Connector/Net 6.0 will have it... you can check it out here:

[Update April 2016] This answer is now outdated, custom naked domain mapping is supported, see Lawrence Mok's answer.

I have figured it out!

First off: it is impossible to link something like mydomain.com with your appspot app. This is considered a naked domain, which is not supported by Google App Engine (anymore). Strictly speaking, the answer to my question has to be "impossible". Read on...

All you can do is add subdomains pointing to your app, e.g myappid.mydomain.com. The key to get your top level domain linked to your app is to realize that www is a subdomain like any other!

myappid.mydomain.com is treated exactly the same as www.mydomain.com!

Here are the steps:

1. Go to appengine.google.com, open your app
2. Administration > Versions > Add Domain... (your domain has to be linked to your Google Apps account, follow the steps to do that including the domain verification.)
3. Go to www.google.com/a/yourdomain.com
4. Dashboard > your app should be listed here. Click on it.
5. myappid settings page > Web address > Add new URL
6. Simply enter www and click Add
7. Using your domain hosting provider's web interface, add a CNAME for www for your domain and point to ghs.googlehosted.com

Now you have www.mydomain.com linked to your app.

I wished this would have been more obvious in the documentation...Good luck!

If you are having a problem with NULL values, use the COALESCE function to replace the NULL with the value of your choice. Your query would then look like this:

SELECT (COALESCE(field1, '') + '' + COALESCE(field2, '') + '' + COALESCE(field3,'')) FROM table1

just create new android project and copy paste my code and have fun! :) also remember in xml i have image view and his background images replace with yout own images thanks..

The Status Value being returned by a Stored Procedure can only be an INT datatype. You cannot return other datatypes in the RETURN statement.

From Lesson 2: Designing Stored Procedures:

Every stored procedure can return an integer value known as the execution status value or return code.

If you still want a table returned from the SP, you'll either have to work the record set returned from a SELECT within the SP or tie into an OUTPUT variable that passes an XML datatype.

Install gcc multiple library.

sudo apt-get install gcc-multilib

Once you define a class (MyDTOClass) indicating what you expect to receive it should be as simple as...

public ActionResult Post([FromBody]MyDTOClass inputData){
 ... do something with input data ...
}

Thx to Julias:

Parsing Json .Net Web Api

Make sure your request is sent with the http header:

Content-Type: application/json

The following code allows you to specify the row/column number and get the resulting cell value:

WebDriver driver = new ChromeDriver();
WebElement base = driver.findElement(By.className("Table"));
tableRows = base.findElements(By.tagName("tr"));
List<WebElement> tableCols = tableRows.get([ROW_NUM]).findElements(By.tagName("td"));
String cellValue = tableCols.get([COL_NUM]).getText();

Followings gives dimensions as well as channels:

import numpy as np
from PIL import Image

with Image.open(filepath) as img:
    shape = np.array(img).shape

I believe this is what you are looking for:

maybe doesnt exists javaee-api-7.0.jar. download this jar and on your project right clik

1. on your project right click
2. build path
3. Configure build path
4. Add external Jars
5. javaee-api-7.0.jar choose
6. Apply and finish

This should technically be achievable using window.location.reload():

HTML:

<button (click)="refresh()">Refresh</button>

TS:

refresh(): void {
    window.location.reload();
}

Update:

Here is a basic StackBlitz example showing the refresh in action. Notice the URL on "/hello" path is retained when window.location.reload() is executed.

Yes, you could use a transparent div positioned over the iframe area, with a loader gif as only background.

Then you can attach an onload event to the iframe:

 $(document).ready(function() {

   $("iframe#id").load(function() {
      $("#loader-id").hide();
   });
});

If your console does not show (base) after running conda activate base, then try running:

conda init

Then running conda activate <your_env> should show the name of (<your_env>) at the beginning of the shell prompt.

This worked for me on Windows. My PATH environment variable was set properly so conda activate base did not raise any error but quietly failed.

I'd use the word 'return' to remember, the r comes before the n.

Now that it's 2018 here's a quick and simple method.

This will add an event listener, but if it already fired we'll check that the dom is in a ready state or that it's complete. This can fire before or after sub-resources have finished loading (images, stylesheets, frames, etc).

function domReady(fn) {_x000D_
  // If we're early to the party_x000D_
  document.addEventListener("DOMContentLoaded", fn);_x000D_
  // If late; I mean on time._x000D_
  if (document.readyState === "interactive" || document.readyState === "complete" ) {_x000D_
    fn();_x000D_
  }_x000D_
}_x000D_
_x000D_
domReady(() => console.log("DOM is ready, come and get it!"));

Update

Here's some quick utility helpers using standard ES6 Import & Export I wrote that include TypeScript as well. Maybe I can get around to making these a quick library that can be installed into projects as a dependency.

JavaScript

export const domReady = (callBack) => {
  if (document.readyState === "loading") {
    document.addEventListener('DOMContentLoaded', callBack);
  }
  else {
    callBack();
  }
}

export const windowReady = (callBack) => {
  if (document.readyState === 'complete') {
    callBack();
  }
  else {
    window.addEventListener('load', callBack);
  }
}

TypeScript

export const domReady = (callBack: () => void) => {
  if (document.readyState === "loading") {
    document.addEventListener('DOMContentLoaded', callBack);
  }
  else {
    callBack();
  }
}

export const windowReady = (callBack: () => void) => {
  if (document.readyState === 'complete') {
    callBack();
  }
  else {
    window.addEventListener('load', callBack);
  }
}

Promises

export const domReady = new Promise(resolve => {
  if (document.readyState === "loading") {
    document.addEventListener('DOMContentLoaded', resolve);
  }
  else {
    resolve();
  }
});

export const windowReady = new Promise(resolve => {
  if (document.readyState === 'complete') {
    resolve();
  }
  else {
    window.addEventListener('load', resolve);
  }
});

set #container div top to zero

#container{ 


 top: 0;



}

For others who ran into this issue in a project that is not using a sonar-runners.property file, you may find (as I did) that you need to tweak your pom.xml file, adding a sonar.host.url property.

For example, I needed to add the following line under the 'properties' element:

For those who still have this error even if they have tried the solutions mentioned before, try this it works on windows 10/ macOS and linux (run in the command line):

1. flutter channel dev
2. flutter upgrade
3. flutter config --android-studio-dir="C:\Program Files\Android\Android Studio"

Many of us know that the Popular Method of Escaping Single Quotes is by Doubling them up easily like below.

PRINT 'It''s me, Arul.';

we are going to look on some other alternate ways of escaping the single quotes.

1.UNICODE Characters

39 is the UNICODE character of Single Quote. So we can use it like below.

PRINT 'Hi,it'+CHAR(39)+'s Arul.';
PRINT 'Helo,it'+NCHAR(39)+'s Arul.';

2.QUOTED_IDENTIFIER

Another simple and best alternate solution is to use QUOTED_IDENTIFIER. When QUOTED_IDENTIFIER is set to OFF, the strings can be enclosed in double quotes. In this scenario, we don’t need to escape single quotes. So,this way would be very helpful while using lot of string values with single quotes. It will be very much helpful while using so many lines of INSERT/UPDATE scripts where column values having single quotes.

SET QUOTED_IDENTIFIER OFF;
PRINT "It's Arul."
SET QUOTED_IDENTIFIER ON;

CONCLUSION

The above mentioned methods are applicable to both AZURE and On Premises .

If you mean using a literal, you simply have to create a binary string:

insert into Files (FileId, FileData) values (1, 0x010203040506)

And you will have a record with a six byte value for the FileData field.

You indicate in the comments that you want to just specify the file name, which you can't do with SQL Server 2000 (or any other version that I am aware of).

You would need a CLR stored procedure to do this in SQL Server 2005/2008 or an extended stored procedure (but I'd avoid that at all costs unless you have to) which takes the filename and then inserts the data (or returns the byte string, but that can possibly be quite long).

In regards to the question of only being able to get data from a SP/query, I would say the answer is yes, because if you give SQL Server the ability to read files from the file system, what do you do when you aren't connected through Windows Authentication, what user is used to determine the rights? If you are running the service as an admin (God forbid) then you can have an elevation of rights which shouldn't be allowed.

<?php

header("Content-Type: $type");
readfile($file);

That's the short version. There's a few extra little things you can do to make things nicer, but that'll work for you.

C++ has Automatic variables - not Stack variables.

Automatic variable means that C++ compiler handles memory allocation / free by itself. C++ can automatically handle objects of any class - no matter whether it has dynamically allocated members or not. It's achieved by strong guarantee of C++ that object's destructor will be called automatically when execution is going out of scope where automatic variable was declared. Inside of a C++ object can be a lot of dynamic allocations with new in constructor, and when such an object is declared as an automatic variable - all dynamic allocations will be performed, and freed then in destructor.

Stack variables in C can't be dynamically allocated. Stack in C can store pointers, or fixed arrays or structs - all of fixed size, and these things are being allocated in memory in linear order. When a C program frees a stack variable - it just moves stack pointer back and nothing more.

Even though C++ programs can use Stack memory segment for storing primitive types, function's args, or other, - it's all decided by C++ compiler, not by program developer. Thus, it is conceptually wrong to equal C++ automatic variables and C stack variables.

To seach within a repository, add the URL parametes /search?q=search_terms at the root of the repo, for example:

https://github.com/bmewburn/vscode-intelephense/search?q=phpstorm

In the above example, it returns 2 results in Code and 160 results in Issues.

Many ways this can be achieved.

Simple approach should be taking Substring of an input string.

var result = input.Substring(input.Length - 3);

Another approach using Regular Expression to extract last 3 characters.

var result = Regex.Match(input,@"(.{3})\s*$");

Either you can Downgrade to JRE 1.7.49

or if you want to run on JRE 8

Step to fix:-

• Go to Lib folder of Liferay Tomcat .

• Replace :- ecj-3.7.2.jar with ecj-4.4.2.

• Restart the Server

YOUR-COMMAND &> YOUR-LOG.log &    

This should run the command and assign a process id you can simply tail -f YOUR-LOG.log to see results written to it as they happen. you can log out anytime and the process will carry on

One API method I use when I'm not sure what the bean name is org.springframework.beans.factory.ListableBeanFactory#getBeanNamesForType(java.lang.Class<?>). I simple pass it the class type and it retrieves a list of beans for me. You can be as specific or general as you'd like to retrieve all the beans relate with that type and its subtypes, example

@Autowired
ApplicationContext ctx

...

SomeController controller = ctx.getBeanNamesForType(SomeController)

According to Wikipedia:

A segmentation fault occurs when a program attempts to access a memory location that it is not allowed to access, or attempts to access a memory location in a way that is not allowed (for example, attempting to write to a read-only location, or to overwrite part of the operating system).

I've set up a JSFiddle to test several different solutions to this problem. Based on the [vague] criteria of

1) Maximum flexibility

2) No weird behavior

The accepted answer here of

img { display: block; }

which is recommended by a lot of people (such as in this excellent article), actually ranks fourth.

1st, 2nd, and 3rd place are all a toss-up between these three solutions:

1) The solution given by @Dave Kok and @Hasan Gursoy:

img { vertical-align: top; } /* or bottom */

pros:

• All display values work on both the parent and img.
• No very strange behavior; any siblings of the img fall where you'd expect them to.
• Very efficient.

cons:

• In the [perfectly valid] case of both the parent and img having `display: inline`, the value of this property can determine the position of the img's parent (a bit strange).

2) Setting font-size: 0; on the parent element:

.parent {
    font-size: 0;
    vertical-align: top;
}
.parent > * {
    font-size: 16px;
    vertical-align: top;
}

Since this one [kind of] requires vertical-align: top on the img, this is basically an extension of the 1st solution.

pros:

• All display values work on both the parent and img.
• No very strange behavior; any siblings of the img fall where you'd expect them to.
• Fixes the inline whitespace problem for any siblings of the img.
• Although this still moves the position of the parent in the case of the parent and img both having `display: inline`, at least you can't see the parent anymore.

cons:

• Less efficient code.
• This assumes "correct" markup; if the img has text node siblings, they won't show up.

3) Setting line-height: 0 on the parent element:

.parent {
    line-height: 0;
    vertical-align: top;
}
.parent > * {
    line-height: 1.15;
    vertical-align: top;
}

Similar to the 2nd solution in that, to make it fully flexible, it basically becomes an extension of the 1st.

pros:

• Behaves like the first two solutions on all display combinations except when the parent and img have `display: inline`.

cons:

• Less efficient code.
• In the case of both the parent and img having `display: inline`, we get all sorts of crazy. (Maybe playing with the `line-height` property isn't the best idea...)

So there you have it. I hope this helps some poor soul.

Replace

volume = (4 / 3) Math.PI * Math.pow(radius, 3);

With:

volume = (4 * Math.PI * Math.pow(radius, 3)) / 3;

Because to declare a type, its size needs to be known. You can forward declare a pointer to the type, or typedef a pointer to the type.

If you really want to, you can use the pimpl idiom to keep the includes down. But if you want to use a type, rather than a pointer, the compiler has to know its size.

Edit: j_random_hacker adds an important qualification to this answer, basically that the size needs to be know to use the type, but a forward declaration can be made if we only need to know the type exists, in order to create pointers or references to the type. Since the OP didn't show code, but complained it wouldn't compile, I assumed (probably correctly) that the OP was trying to use the type, not just refer to it.

If these strings are currently in the db, you can skip php by using mysql's STR_TO_DATE() function.

I assume the strings use a format like month/day/year where month and day are always 2 digits, and year is 4 digits.

UPDATE some_table
   SET new_column = STR_TO_DATE(old_column, '%m/%d/%Y')

You can support other date formats by using other format specifiers.

This worked for me:

find /A -type d -exec chmod 0755 {} \;
find /A -type f -exec chmod 0644 {} \;

For JavaScript arrays, you use push().

var a = [];
a.push(12);
a.push(32);

For jQuery objects, there's add().

$('div.test').add('p.blue');

Note that while push() modifies the original array in-place, add() returns a new jQuery object, it does not modify the original one.

New in Python 3.7+

The datetime standard library introduced a function for inverting datetime.isoformat().

classmethod datetime.fromisoformat(date_string):

Return a datetime corresponding to a date_string in one of the formats emitted by date.isoformat() and datetime.isoformat().

Specifically, this function supports strings in the format(s):

YYYY-MM-DD[*HH[:MM[:SS[.mmm[mmm]]]][+HH:MM[:SS[.ffffff]]]]

where * can match any single character.

Caution: This does not support parsing arbitrary ISO 8601 strings - it is only intended as the inverse operation of datetime.isoformat().

Example of use:

from datetime import datetime

date = datetime.fromisoformat('2017-01-01T12:30:59.000000')

I did this and it works for me. "content" is placesContent object. not the html content!

var placesContent = $('#placescontent');
$('#places').popover({
        trigger: "click",
        placement: "bottom",
        container: 'body',
        html : true,
        content : placesContent,
    });

$('#places').on('shown.bs.popover', function(){
  $('#addPlaceBtn').on('click', addPlace);
}

<div id="placescontent"><div id="addPlaceBtn">Add</div></div>

I know that it may be not directly answer to your question, because you said that null values have to be supported.

But I just want to note that supporting nulls in compareTo is not in line with compareTo contract described in official javadocs for Comparable:

Note that null is not an instance of any class, and e.compareTo(null) should throw a NullPointerException even though e.equals(null) returns false.

So I would either throw NullPointerException explicitly or just let it be thrown first time when null argument is being dereferenced.

completing Kai Noack's answer, I would do this:

var originalTitle = document.title;
document.title = "Print page title";
window.print();
document.title = originalTitle;

this way once you print page, This will return to have its original title.

At the Maven repo, there are samples to add the dependency in maven, sbt, gradle, etc.

https://mvnrepository.com/artifact/org.apache.httpcomponents/httpcore/4.4.11

ie for Maven, you just create a project, for example

mvn archetype:generate -DarchetypeGroupId=org.apache.maven.archetypes -DarchetypeArtifactId=maven-archetype-quickstart -DarchetypeVersion=1.4

then look at the pom.xml, then at the library at the dependencies xml element:

<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpcore</artifactId>
    <version>4.4.11</version>
</dependency>

For sbt do something like

sbt new scala/hello-world.g8

then edit the build.sbt to add the library

libraryDependencies += "org.apache.httpcomponents" % "httpcore" % "4.4.11"

Ctrl + 2: Access the popup list of methods and symbols in the current file.

This is super useful because with this shortcut you can navigate through a file entirely using the keyboard. When you get to the list, start typing characters and the list will type-select to the symbol you are looking for.

If you are sure that your entity has not been modified (or if you agree any modification will be lost), then you may reattach it to the session with lock.

session.lock(entity, LockMode.NONE);

It will lock nothing, but it will get the entity from the session cache or (if not found there) read it from the DB.

It's very useful to prevent LazyInitException when you are navigating relations from an "old" (from the HttpSession for example) entities. You first "re-attach" the entity.

Using get may also work, except when you get inheritance mapped (which will already throw an exception on the getId()).

entity = session.get(entity.getClass(), entity.getId());

You open the variable "file" as a read only then attempt to write to it:

file = open('ValidEmails.txt','r')

Instead, use the 'w' flag.

file = open('ValidEmails.txt','w')
...
file.write(email)

Create a new "Empty Project" , Add your Cpp file to the new project, delete the line that includes stdafx.

Done.

The project no longer needs the stdafx. It is added automatically when you create projects with installed templates.

The Tumbler V2 API provides a pure JSON response but requires jumping through a few hoops:

1. Register an application
2. Get your "OAuth Consumer Key" which you'll find when editing your application from the apps page
3. Use any of the methods that only require an API Key for authentication as this can be passed in the URL, e.g. posts
4. Enjoy your JSON response!

We use bootstrap 4 in asp.net core but reference the libraries from "npm" using the "Package Installer" extension and found this to be better than Nuget for Javascript/CSS libraries.

We then use the "Bundler & Minifier" extension to copy the relevant files for distribution (from the npm node_modules folder, which sits outside the project) into wwwroot as we like for development/deployment.

i guess this one will be handy as well as precise

If you want to set the font-size as a percentage of the viewport width, use the vwunit:

#mydiv { font-size: 5vw; }

The other alternative is to use SVG embedded in the HTML. It will just be a few lines. The font-size attribute to the text element will be interpreted as "user units", for instance those the viewport is defined in terms of. So if you define viewport as 0 0 100 100, then a font-size of 1 will be one one-hundredth of the size of the svg element.

And no, there is no way to do this in CSS using calculations. The problem is that percentages used for font-size, including percentages inside a calculation, are interpreted in terms of the inherited font size, not the size of the container. CSS could use a unit called bw (box-width) for this purpose, so you could say div { font-size: 5bw; }, but I've never heard this proposed.

You can use proxytunnel:

proxytunnel -p yourproxy:8080 -d www.google.com:443 -a 7000

and then you can do this:

Hope this can help you!

Beside all the above hints like track by and smaller loops, this one also helped me a lot

<span ng-bind="::stock.name"></span>

this piece of code would print the name once it has been loaded, and stop watching it after that. Similarly, for ng-repeats, it could be used as

<div ng-repeat="stock in ::ctrl.stocks">{{::stock.name}}</div>

however it only works for AngularJS version 1.3 and higher. From http://www.befundoo.com/blog/optimizing-ng-repeat-in-angularjs/

Keep dump/backup of all databases.This is not 100% reliable process. Manual backup: Go to datadir path (see in my.ini file) and copy all databases.sql files from data folder

This error will be thrown when unexpectedly MySql service is stopped or disabled and not able to restart in the Services.

First try restart PC and MySql Service couple of times ,if still getting same error then follow the steps.

Keep open the following wizards and folders:

• C:\Program Files (x86)\MySQL\MySQL Server 5.5\bin

• C:\Program Files (x86)\MySQL\MySQL Server 5.5

Services list ->select MySql Service.

1. Go to installed folder MySql, double-click on instance config C:\Program Files (x86)\MySQL\MySQL Server 5.5\bin\MySqlInstanceConfig.exe

Then select remove instance and click on next to remove non-working MySql service instance. See in the Service list (refresh F5) where MySql service should not be found.

2. Now go to C:\Program Files (x86)\MySQL\MySQL Server 5.5 open my.ini file check below

#Path to installation directory

basedir="C:/Program Files (x86)/MySQL/MySQL Server 5.5/"

#Path to data directory

datadir="C:/ProgramData/MySQL/MySQL Server 5.5/Data/"

3. Choose data dir Go to "C:/ProgramData/MySQL/MySQL Server 5.5/Data/" It contains all tables data and log info, ib data, user.err,user.pid . Delete

   • log files,
   • ib data,
   • user.err,
   • user.pid files.

(why because to create new MySql instance or when reconfiguring MySql service by clicking on MySqlInstanceConfig.exe and selecting default configure, after enter choosing password and clicking on execute the wizard will try to create these log files or will try to append the text again to these log files and other files which will make the setup wizard as unresponding and finally end up with configuration not done).

4. After deleted selected files from C:/ProgramData/MySQL/MySQL Server 5.5/Data/ go to C:\Program Files (x86)\MySQL\MySQL Server 5.5

Delete the selected files my.ini and and other .bak format files which cause for the instance config.exe un-responding.

5. C:\Program Files (x86)\MySQL\MySQL Server 5.5\bin\MySqlInstanceConfig.exe Select MySqlInstanceConfig.exe and double-click on it and select default configuration or do the regular set up that we do when installing MySql server first time.

You can supply a function argument to scale, and ggplot will use that function to calculate the tick locations.

library(ggplot2)
dat <- data.frame(x = rnorm(100), y = rnorm(100))
number_ticks <- function(n) {function(limits) pretty(limits, n)}

ggplot(dat, aes(x,y)) +
  geom_point() +
  scale_x_continuous(breaks=number_ticks(10)) +
  scale_y_continuous(breaks=number_ticks(10))

Try this:

Define a funciton:

<?php
function phpAlert($msg) {
    echo '<script type="text/javascript">alert("' . $msg . '")</script>';
}
?>

Call it like this:

<?php phpAlert(   "Hello world!\\n\\nPHP has got an Alert Box"   );  ?>

My host is Windows10 my VM guest is ubuntu build by vagrant. This worked for me:

Or in pure WPF use PointToScreen.

Sample helper method:

// Gets the absolute mouse position, relative to screen
Point GetMousePos() => _window.PointToScreen(Mouse.GetPosition(_window));

var pdf = MyPdf.pdf;
window.open(pdf);

This will open the pdf document in a full window from JavaScript

A function to open windows would look like this:

function openPDF(pdf){
  window.open(pdf);
  return false;
}

Anyway inline css is never recommended. We used styled-components in our project which is based on JSS. It protects css overriding by adding dynamic class names on components. You can also add css values based on the props passed.

For those wanting a simple solution without jQuery, here's a way.

textarea and message container to put in your form:

<textarea onKeyUp="count_it()" id="text" name="text"></textarea>
Length <span id="counter"></span>

JavaScript:

<script>
function count_it() {
    document.getElementById('counter').innerHTML = document.getElementById('text').value.length;
}
count_it();
</script>

The script counts the characters initially and then for every keystroke and puts the number in the counter span.

Your CRON should look like this:

*/5 * * * *

CronWTF is really usefull when you need to test out your CRON settings.

Might be a good idea to pipe the output into a log file so you can see if your script is throwing any errors too - since you wont see them in your terminal.

Also try using a shebang at the top of your PHP file, so the system knows where to find PHP. Such as:

#!/usr/bin/php

that way you can call the whole thing like this

*/5 * * * * php /path/to/script.php > /path/to/logfile.log

Previous answers assume that the branch to be reset is the current branch (checked out). In comments, OP hap497 clarified that the branch is indeed checked out, but this is not explicitly required by the original question. Since there is at least one "duplicate" question, Reset branch completely to repository state, which does not assume that the branch is checked out, here's an alternative:

If branch "mybranch" is not currently checked out, to reset it to remote branch "myremote/mybranch"'s head, you can use this low-level command:

git update-ref refs/heads/mybranch myremote/mybranch

This method leaves the checked out branch as it is, and the working tree untouched. It simply moves mybranch's head to another commit, whatever is given as the second argument. This is especially helpful if multiple branches need to be updated to new remote heads.

Use caution when doing this, though, and use gitk or a similar tool to double check source and destination. If you accidentally do this on the current branch (and git will not keep you from this), you may become confused, because the new branch content does not match the working tree, which did not change (to fix, update the branch again, to where it was before).

The easystream open source library has direct support to convert an OutputStream to an InputStream: http://io-tools.sourceforge.net/easystream/tutorial/tutorial.html

// create conversion
final OutputStreamToInputStream<Void> out = new OutputStreamToInputStream<Void>() {
    @Override
    protected Void doRead(final InputStream in) throws Exception {
           LibraryClass2.processDataFromInputStream(in);
           return null;
        }
    };
try {   
     LibraryClass1.writeDataToTheOutputStream(out);
} finally {
     // don't miss the close (or a thread would not terminate correctly).
     out.close();
}

They also list other options: http://io-tools.sourceforge.net/easystream/outputstream_to_inputstream/implementations.html

• Write the data the data into a memory buffer (ByteArrayOutputStream) get the byteArray and read it again with a ByteArrayInputStream. This is the best approach if you're sure your data fits into memory.
• Copy your data to a temporary file and read it back.
• Use pipes: this is the best approach both for memory usage and speed (you can take full advantage of the multi-core processors) and also the standard solution offered by Sun.
• Use InputStreamFromOutputStream and OutputStreamToInputStream from the easystream library.

It is possible to define util methods which solves this in an almost pretty way with Java 8 lambda.

This is a variation of H-MANs solution but it uses overloaded methods with multiple arguments to handle multiple steps instead of catching NullPointerException.

Even if I think this solution is kind of cool I think I prefer Helder Pereira's seconds one since that doesn't require any util methods.

void example() {
    Entry entry = new Entry();
    // This is the same as H-MANs solution 
    Person person = getNullsafe(entry, e -> e.getPerson());    
    // Get object in several steps
    String givenName = getNullsafe(entry, e -> e.getPerson(), p -> p.getName(), n -> n.getGivenName());
    // Call void methods
    doNullsafe(entry, e -> e.getPerson(), p -> p.getName(), n -> n.nameIt());        
}

/** Return result of call to f1 with o1 if it is non-null, otherwise return null. */
public static <R, T1> R getNullsafe(T1 o1, Function<T1, R> f1) {
    if (o1 != null) return f1.apply(o1);
    return null; 
}

public static <R, T0, T1> R getNullsafe(T0 o0, Function<T0, T1> f1, Function<T1, R> f2) {
    return getNullsafe(getNullsafe(o0, f1), f2);
}

public static <R, T0, T1, T2> R getNullsafe(T0 o0, Function<T0, T1> f1, Function<T1, T2> f2, Function<T2, R> f3) {
    return getNullsafe(getNullsafe(o0, f1, f2), f3);
}


/** Call consumer f1 with o1 if it is non-null, otherwise do nothing. */
public static <T1> void doNullsafe(T1 o1, Consumer<T1> f1) {
    if (o1 != null) f1.accept(o1);
}

public static <T0, T1> void doNullsafe(T0 o0, Function<T0, T1> f1, Consumer<T1> f2) {
    doNullsafe(getNullsafe(o0, f1), f2);
}

public static <T0, T1, T2> void doNullsafe(T0 o0, Function<T0, T1> f1, Function<T1, T2> f2, Consumer<T2> f3) {
    doNullsafe(getNullsafe(o0, f1, f2), f3);
}


class Entry {
    Person getPerson() { return null; }
}

class Person {
    Name getName() { return null; }
}

class Name {
    void nameIt() {}
    String getGivenName() { return null; }
}

For faster overall reading / uploading a (large) file, consider increasing the size of bufferSize (Source.DefaultBufSize set to 2048), for instance as follows,

val file = new java.io.File("myFilename")
io.Source.fromFile(file, bufferSize = Source.DefaultBufSize * 2)

Note Source.scala. For further discussion see Scala fast text file read and upload to memory.

You can try overflow css property.

This is working for me:

$user_info = DB::table('usermetas')
                 ->select('browser', DB::raw('count(*) as total'))
                 ->groupBy('browser')
                 ->get();

If you just want to change file permissions, you want to be careful about using -R on chmod since it will change anything, files or folders. If you are doing a relative change (like adding write permission for everyone), you can do this:

sudo chmod -R a+w /var/www

But if you want to use the literal permissions of read/write, you may want to select files versus folders:

sudo find /var/www -type f -exec chmod 666 {} \;

(Which, by the way, for security reasons, I wouldn't recommend either of these.)

Or for folders:

sudo find /var/www -type d -exec chmod 755 {} \;

Quick fix. Create whole structure tr > td > button; then find button inside; attach event on it; end filtering of chain and at the and insert it into dom.

$("#myButton").click(function () {
    var test = $('<tr><td><button>Test</button></td></tr>').find('button').click(function () {
        alert('hi');
    }).end();

    $("#nodeAttributeHeader").attr('style', 'display: table-row;');
    $("#addNodeTable tr:last").before(test);
});

Tested and working!

Here is example with only CSS for that. In example I'm using SASS and SLIM.

https://codepen.io/Darex1991/pen/zBxPxe

Slim:

a.btn.btn--joined-state
  span joined
  span leave

SASS:

Override the default input onChange behavior (call the function only when control loss focus and value was change)

NOTE: ngChange is not similar to the classic onChange event it firing the event while the value is changing This directive stores the value of the element when it gets the focus
On blurs it checks whether the new value has changed and if so it fires the event

@param {String} - function name to be invoke when the "onChange" should be fired

@example < input my-on-change="myFunc" ng-model="model">

angular.module('app', []).directive('myOnChange', function () { 
    return {
        restrict: 'A',
        require: 'ngModel',
        scope: {
            myOnChange: '='
        },
        link: function (scope, elm, attr) {
            if (attr.type === 'radio' || attr.type === 'checkbox') {
                return;
            }
            // store value when get focus
            elm.bind('focus', function () {
                scope.value = elm.val();

            });

            // execute the event when loose focus and value was change
            elm.bind('blur', function () {
                var currentValue = elm.val();
                if (scope.value !== currentValue) {
                    if (scope.myOnChange) {
                        scope.myOnChange();
                    }
                }
            });
        }
    };
});

To find all files modified in the last 24 hours use the one below. The -1 here means changed 1 day or less ago.

find . -mtime -1 -ls

You can do this in 2 steps:

1: Change the input type(In your EditText field) in the layout file to android:inputType="number"

2: Use int a = Integer.parseInt(yourEditTextObject.getText().toString());

You need to convert the date time object to a string.

The following code worked for me:

import datetime
collection = []
dateTimeString = str(datetime.date.today())
collection.append(dateTimeString)
print collection

Let me know if you need any more help.

You have to add it to /etc/paths.

Reference (which works for me) : Here

A solution that does not add extra leading or trailing whitespace:

awk '{ for(i=4; i<NF; i++) printf "%s",$i OFS; if(NF) printf "%s",$NF; printf ORS}'

### Example ###
$ echo '1 2 3 4 5 6 7' |
  awk '{for(i=4;i<NF;i++)printf"%s",$i OFS;if(NF)printf"%s",$NF;printf ORS}' |
  tr ' ' '-'
4-5-6-7

Sudo_O proposes an elegant improvement using the ternary operator NF?ORS:OFS

$ echo '1 2 3 4 5 6 7' |
  awk '{ for(i=4; i<=NF; i++) printf "%s",$i (i==NF?ORS:OFS) }' |
  tr ' ' '-'
4-5-6-7

EdMorton gives a solution preserving original whitespaces between fields:

$ echo '1   2 3 4   5    6 7' |
  awk '{ sub(/([^ ]+ +){3}/,"") }1' |
  tr ' ' '-'
4---5----6-7

BinaryZebra also provides two awesome solutions:
^{(these solutions even preserve trailing spaces from original string)}

$ echo -e ' 1   2\t \t3     4   5   6 7 \t 8\t ' |
  awk -v n=3 '{ for ( i=1; i<=n; i++) { sub("^["FS"]*[^"FS"]+["FS"]+","",$0);} } 1 ' |
  sed 's/ /./g;s/\t/->/g;s/^/"/;s/$/"/'
"4...5...6.7.->.8->."

$ echo -e ' 1   2\t \t3     4   5   6 7 \t 8\t ' |
  awk -v n=3 '{ print gensub("["FS"]*([^"FS"]+["FS"]+){"n"}","",1); }' |
  sed 's/ /./g;s/\t/->/g;s/^/"/;s/$/"/'
"4...5...6.7.->.8->."

The solution given by larsr in the comments is almost correct:

$ echo '1 2 3 4 5 6 7' | 
  awk '{for (i=3;i<=NF;i++) $(i-2)=$i; NF=NF-2; print $0}' | tr  ' ' '-'
3-4-5-6-7

This is the fixed and parametrized version of larsr solution:

$ echo '1 2 3 4 5 6 7' | 
  awk '{for(i=n;i<=NF;i++)$(i-(n-1))=$i;NF=NF-(n-1);print $0}' n=4 | tr ' ' '-'
4-5-6-7

All other answers before Sep-2013 are nice but add extra spaces:

• Example of answer adding extra leading spaces:

  $ echo '1 2 3 4 5 6 7' | 
    awk '{$1=$2=$3=""}1' | 
    tr  ' ' '-'
  ---4-5-6-7
  

• Example of answer adding extra trailing space

  $ echo '1 2 3 4 5 6 7' | 
    awk '{for(i=4;i<=13;i++)printf "%s ",$i;printf "\n"}' | 
    tr ' ' '-'
  4-5-6-7-------
  

I found that the following code, when inserted into the site's footer, worked well enough:

<script type="text/javascript">
$("#nav-ask").remove();
</script>

This may or may not require jquery. The site I'm editing has jquery, but unfortunately I'm no javascripter, so I only have a limited knowledge of what's going on here, and the requirements of this code snippet...

Unfortunately, there is no cross-browser support for opening a confirmation dialog that is not the default OK/Cancel pair. The solution you provided uses VBScript, which is only available in IE.

I would suggest using a Javascript library that can build a DOM-based dialog instead. Try Jquery UI: http://jqueryui.com/

Take for example, you want to write Junit for below mentioned code fragment

public int divideByZeroDemo(int a,int b){

    return a/b;
}

public void exceptionWithMessage(String [] arr){

    throw new ArrayIndexOutOfBoundsException("Array is out of bound");
}

The above code is to test for some unknown exception that may occur and the below one is to assert some exception with custom message.

 @Rule
public ExpectedException exception=ExpectedException.none();

private Demo demo;
@Before
public void setup(){

    demo=new Demo();
}
@Test(expected=ArithmeticException.class)
public void testIfItThrowsAnyException() {

    demo.divideByZeroDemo(5, 0);

}

@Test
public void testExceptionWithMessage(){


    exception.expectMessage("Array is out of bound");
    exception.expect(ArrayIndexOutOfBoundsException.class);
    demo.exceptionWithMessage(new String[]{"This","is","a","demo"});
}

Select-Object returns a custom PSObject with just the properties specified. Even with a single property, you don't get the ACTUAL variable; it is wrapped inside the PSObject.

Instead, do:

Get-Date | Select-Object -ExpandProperty DayOfWeek

That will get you the same result as:

(Get-Date).DayOfWeek

The difference is that if Get-Date returns multiple objects, the pipeline way works better than the parenthetical way as (Get-ChildItem), for example, is an array of items. This has changed in PowerShell v3 and (Get-ChildItem).FullPath works as expected and returns an array of just the full paths.

It's probably worth answering that iPads running iOS 13 will have navigator.platform set to MacIntel, which means you'll need to find another way to detect iPadOS devices.

the juicy bits

#include <ctype.h> // isdigit, tolower

from_hex(char ch) {
  return isdigit(ch) ? ch - '0' : tolower(ch) - 'a' + 10;
}

char to_hex(char code) {
  static char hex[] = "0123456789abcdef";
  return hex[code & 15];
}

noting that

char d = from_hex(hex[0]) << 4 | from_hex(hex[1]);

as in

// %7B = '{'

char d = from_hex('7') << 4 | from_hex('B');

Although purely from engineering perspective, indexed views sound like something everybody could use to improve performance but the real life scenario is very different. I have been unsuccessful is using indexed views where I most need them because of too many restrictions on what can be indexed and what cannot.

If you have outer joins in the views, they cannot be used. Also, common table expressions are not allowed... In fact if you have any ordering in subselects or derived tables (such as with partition by clause), you are out of luck too.

That leaves only very simple scenarios to be utilizing indexed views, something in my opinion can be optimized by creating proper indexes on underlying tables anyway.

I will be thrilled to hear some real life scenarios where people have actually used indexed views to their benefit and could not have done without them

This script works only on the path names. It does not require any of the files to exist. If the paths passed are not absolute, the behavior is a bit unusual, but it should work as expected if both paths are relative.

I only tested it on OS X, so it might not be portable.

in your HTML : <input type="file" id="yourFile"> don't forget to reference your js file or put the following script between <script></script> in your script :

According to the discussion here you can directly compare two vectors using

==

if (vector1 == vector2){
   //true
}
else{
   //false
}

list.count(x) returns the number of times x appears in a list

For Spring boot v2.1.3.RELEASE, just add the follow properties into application.propertes:

spring.main.web-application-type=none

window.onresize = function() {
    // your code
};

THE PROBLEM is here: onClick={this.handleButtonChange(false)}

When you pass this.handleButtonChange(false) to onClick, you are actually calling the function with value = false and setting onClick to the function's return value, which is undefined. Also, calling this.handleButtonChange(false) then calls this.setState() which triggers a re-render, resulting in an infinite render loop.

THE SOLUTION is to pass the function in a lambda: onClick={() => this.handleButtonChange(false)}. Here you are setting onClick to equal a function that will call handleButtonChange(false) when the button is clicked.

The below example may help:

function handleButtonChange(value){
  console.log("State updated!")
}

console.log(handleButtonChange(false))
//output: State updated!
//output: undefined

console.log(() => handleButtonChange(false))
//output: ()=>{handleButtonChange(false);}

Here is one approach. ifelse is vectorized and it checks all rows for zero values of b and replaces est with (a - 5)/2.53 if that is the case.

df <- transform(df, est = ifelse(b == 0, (a - 5)/2.53, est))

I got the same error when I changed the Compile SDK version from API:21 to API:16. The problem was, appcompat version. If you need to use an older version of android API, so you have to change this appcompat version also. In my case (for API:16), I had to use appcompat-v7:19.+.

So I replace dependencies in build.gradle as follows,

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:19.+'
}

And make sure you have older versions of appcompat versions on your SDK

JavaScript is executed in the browser, which is pretty far removed from Eclipse. Eclipse would have to somehow hook into the browser's JavaScript engine to debug it. Therefore there's no built-in debugging of JavaScript via Eclipse, since JS isn't really its main focus anyways.

However, there are plug-ins which you can install to do JavaScript debugging. I believe the main one is the AJAX Toolkit Framework (ATF). It embeds a Mozilla browser in Eclipse in order to do its debugging, so it won't be able to handle cross-browser complications that typically arise when writing JavaScript, but it will certainly help.

Test the return value of grep:

./somecommand | grep 'string' &> /dev/null
if [ $? == 0 ]; then
   echo "matched"
fi

which is done idiomatically like so:

if ./somecommand | grep -q 'string'; then
   echo "matched"
fi

and also:

./somecommand | grep -q 'string' && echo 'matched'

Better use Uri.IsWellFormedUriString(string uriString, UriKind uriKind). http://msdn.microsoft.com/en-us/library/system.uri.iswellformeduristring.aspx

Example :-

 if(Uri.IsWellFormedUriString(slct.Text,UriKind.Absolute))
 {
        Uri uri = new Uri(slct.Text);
        if (DeleteFileOnServer(uri))
        {
          nn.BalloonTipText = slct.Text + " has been deleted.";
          nn.ShowBalloonTip(30);
        }
 }

Step For Windows

1. press the ctrl + r.then type cmd and hit enter.

2. now command prompt will be open.

3. after the type cd filepath of file. ex(cd C:\Users\user\Desktop\ ) then hit the enter.

4. please check if npm installed or not using this command node -v. then if you installed will get node version.
5. type the command on command prompt like this node filename.js . example(node app.js)

C:\Users\user\Desktop>node app.js

Is it possible to add onclick to a div and have it occur if any area of the div is clicked.

Yes … although it should be done with caution. Make sure there is some mechanism that allows keyboard access. Build on things that work

If yes then why is the onclick method not going through to my div.

You are assigning a string where a function is expected.

divTag.onclick = printWorking;

There are nicer ways to assign event handlers though, although older versions of Internet Explorer are sufficiently different that you should use a library to abstract it. There are plenty of very small event libraries and every major library jQuery) has event handling functionality.

That said, now it is 2019, older versions of Internet Explorer no longer exist in practice so you can go direct to addEventListener

SET XACT_ABORT ON instructs SQL Server to rollback the entire transaction and abort the batch when a run-time error occurs. It covers you in cases like a command timeout occurring on the client application rather than within SQL Server itself (which isn't covered by the default XACT_ABORT OFF setting.)

Since a query timeout will leave the transaction open, SET XACT_ABORT ON is recommended in all stored procedures with explicit transactions (unless you have a specific reason to do otherwise) as the consequences of an application performing work on a connection with an open transaction are disastrous.

There's a really great overview on Dan Guzman's Blog,

From here

<nul set /p =Testing testing

and also to echo beginning with spaces use

echo.Message goes here

If you need the port number also, you can use

Request.Url.Authority

Example:

string url = Request.Url.Authority + HttpContext.Current.Request.RawUrl.ToString();

if (Request.ServerVariables["HTTPS"] == "on")
{
    url = "https://" + url;
}
else 
{
    url = "http://" + url;
}

You'll need to add a firewall rule to open inbound access to tcp:9090 to your instances. If you have more than the two instances, and you only want to open 9090 to those two, you'll want to make sure that there is a tag that those two instances share. You can add or update tags via the console or the command-line; I'd recommend using the GUI for that if needed because it handles the read-modify-write cycle with setinstancetags.

If you want to open port 9090 to all instances, you can create a firewall rule like:

gcutil addfirewall allow-9090 --allowed=tcp:9090

which will apply to all of your instances.

If you only want to open port 9090 to the two instances that are serving your application, make sure that they have a tag like my-app, and then add a firewall like so:

gcutil addfirewall my-app-9090 --allowed=tcp:9090 --target_tags=my-app

You can read more about creating and managing firewalls in GCE here.

You can write

i = 5 + tup()[0]

Tuples can be indexed just like lists.

The main difference between tuples and lists is that tuples are immutable - you can't set the elements of a tuple to different values, or add or remove elements like you can from a list. But other than that, in most situations, they work pretty much the same.

Until very recent years, PHP has defined its AST and PHP interpreter has isolated the parser from the evaluation part. During the time when the closure is introduced, PHP's parser is highly coupled with the evaluation.

Therefore when the closure was firstly introduced to PHP, the interpreter has no method to know which which variables will be used in the closure, because it is not parsed yet. So user has to pleased the zend engine by explicit import, doing the homework that zend should do.

This is the so-called simple way in PHP.

You can simply add an inspect() method to your object which will override the representation of object in console.log messages

eg:

var myObject = {
   "a":"a",
   "b":{
      "c":"c",
      "d":{
         "e":"e",
         "f":{
            "g":"g",
            "h":{
               "i":"i"
            }
         }
      }
   }
};
myObject.inspect = function(){ return JSON.stringify( this, null, ' ' ); }

then, your object will be represented as required in both console.log and node shell

Update:

object.inspect has been deprecated ( https://github.com/nodejs/node/issues/15549). Use myObject[util.inspect.custom] instead:

const util = require('util')

var myObject = {
  /* nested properties not shown */
}

myObject[util.inspect.custom] = function(){ return JSON.stringify( this, null, 4 ); }


console.log(util.inspect(myObject))

Just a note that as of Ruby 2.0 there is no need to add # encoding: utf-8. UTF-8 is automatically detected.

In C++11 at least, when the expression used to initialize a local static variable is not a 'constexpr' (cannot be evaluated by the compiler), then initialization must happen during the first call to the function. The simplest example is to directly use a parameter to intialize the local static variable. Thus the compiler must emit code to guess whether the call is the first one or not, which in turn requires a local boolean variable. I've compiled such example and checked this is true by seeing the assembly code. The example can be like this:

void f( int p )
{
  static const int first_p = p ;
  cout << "first p == " << p << endl ;
}

void main()
{
   f(1); f(2); f(3);
}

of course, when the expresion is 'constexpr', then this is not required and the variable can be initialized on program load by using a value stored by the compiler in the output assembly code.

Here are the basics. I'm not sure that any of these count as "clear and simple" though.

sar(1M)

And just what's wrong with sar? :)

This is the format of /etc/crontab:

# .---------------- minute (0 - 59)
# |  .------------- hour (0 - 23)
# |  |  .---------- day of month (1 - 31)
# |  |  |  .------- month (1 - 12) OR jan,feb,mar,apr ...
# |  |  |  |  .---- day of week (0 - 6) (Sunday=0 or 7) OR sun,mon,tue,wed,thu,fri,sat
# |  |  |  |  |
# *  *  *  *  * user-name  command to be executed

I recommend copy & pasting that into the top of your crontab file so that you always have the reference handy. RedHat systems are setup that way by default.

To run something every minute:

* * * * * username /var/www/html/a.php

To run something at midnight of every day:

0 0 * * * username /var/www/html/reset.php

You can either include /usr/bin/php in the command to run, or you can make the php scripts directly executable:

chmod +x file.php

Start your php file with a shebang so that your shell knows which interpreter to use:

#!/usr/bin/php
<?php
// your code here

"use strict";

Basically it enables the strict mode.

Strict Mode is a feature that allows you to place a program, or a function, in a "strict" operating context. In strict operating context, the method form binds this to the objects as before. The function form binds this to undefined, not the global set objects.

As per your comments you are telling some differences will be there. But it's your assumption. The Node.js code is nothing but your JavaScript code. All Node.js code are interpreted by the V8 JavaScript engine. The V8 JavaScript Engine is an open source JavaScript engine developed by Google for Chrome web browser.

So, there will be no major difference how "use strict"; is interpreted by the Chrome browser and Node.js.

Please read what is strict mode in JavaScript.

ECMAScript 6 Code & strict mode. Following is brief from the specification:

10.2.1 Strict Mode Code

An ECMAScript Script syntactic unit may be processed using either unrestricted or strict mode syntax and semantics. Code is interpreted as strict mode code in the following situations:

• Global code is strict mode code if it begins with a Directive Prologue that contains a Use Strict Directive (see 14.1.1).
• Module code is always strict mode code.
• All parts of a ClassDeclaration or a ClassExpression are strict mode code.
• Eval code is strict mode code if it begins with a Directive Prologue that contains a Use Strict Directive or if the call to eval is a direct eval (see 12.3.4.1) that is contained in strict mode code.
• Function code is strict mode code if the associated FunctionDeclaration, FunctionExpression, GeneratorDeclaration, GeneratorExpression, MethodDefinition, or ArrowFunction is contained in strict mode code or if the code that produces the value of the function’s [[ECMAScriptCode]] internal slot begins with a Directive Prologue that contains a Use Strict Directive.
• Function code that is supplied as the arguments to the built-in Function and Generator constructors is strict mode code if the last argument is a String that when processed is a FunctionBody that begins with a Directive Prologue that contains a Use Strict Directive.

Additionally if you are lost on what features are supported by your current version of Node.js, this node.green can help you (leverages from the same data as kangax).

I am not sure about this tutorial but I had the same problem when I forgot to include the file into grunt/gulp minimization process.

grunt.initConfig({
  uglify: {
    my_target: {
      files: {
        'dest/output.min.js': ['src/input1.js', 'src/missing_controller.js']
      }
    }
  }
});

Hope that helps.

For .NET server can configure this in web.config as shown below

 <system.webServer>
   <httpProtocol>
     <customHeaders>
       <add name="Access-Control-Allow-Origin" value="your_clientside_websiteurl" />
     </customHeaders>
   </httpProtocol>
 </system.webServer>

For instance lets say, if the server domain is http://live.makemypublication.com and client is http://www.makemypublication.com then configure in server's web.config as below

 <system.webServer>
   <httpProtocol>
     <customHeaders>
       <add name="Access-Control-Allow-Origin" value="http://www.makemypublication.com" />
     </customHeaders>
  </httpProtocol>
 </system.webServer>

The IDLE shell window is not the same as a terminal shell (e.g. running sh or bash). Rather, it is just like being in the Python interactive interpreter (python -i). The easiest way to run a script in IDLE is to use the Open command from the File menu (this may vary a bit depending on which platform you are running) to load your script file into an IDLE editor window and then use the Run -> Run Module command (shortcut F5).

For beyond compare on Windows 7

git config --global merge.tool bc3
git config --global mergetool.bc3.path "C:\Program Files (x86)\Beyond Compare 3\BCompare.exe"

My SQL teacher said that if you specify both a DEFAULT value and NOT NULLor NULL, DEFAULT should always be expressed before NOT NULL or NULL.

Like this:

ALTER TABLE tbl ADD COLUMN col VARCHAR(20) DEFAULT "MyDefault" NOT NULL

ALTER TABLE tbl ADD COLUMN col VARCHAR(20) DEFAULT "MyDefault" NULL

Then number of columns must match between both parts of the union.

In order to build the full path, you need to "aggregate" all values of the Location column. You still need to select the id and other columns inside the CTE in order to be able to join properly. You get "rid" of them by simply not selecting them in the outer select:

with q as 
(
   select ID, PartOf_LOC_id, Location, ' > ' + Location as path
   from tblLocation 
   where ID = 1 

   union all

   select child.ID, child.PartOf_LOC_id, Location, parent.path + ' > ' + child.Location 
   from tblLocation child
     join q parent on parent.ID = t.LOC_PartOf_ID
)
select path
from q;

In my case it was my AVG anti-virus that triggered the exception.

I added my VS Projects directory to the "Allowed" list. And I had to add the executable to the AVG exceptions list after I copied the .exe to my App directory.

Instead of getting all the table columns using * in your sql statement, you use to specify the table columns you need.

You can use the SQL statement something like:

SELECT CONCAT(FIRSTNAME, ' ', LASTNAME) AS FIRSTNAME FROM customer;

BTW, why couldn't you use FullName instead of FirstName? Like this:

SELECT CONCAT(FIRSTNAME, ' ', LASTNAME) AS 'CUSTOMER NAME' FROM customer;

Add one more line after initializing file object

File fnew = new File("../playlist/" + existingPlaylist.getText() + ".txt");
fnew.createNewFile();

SELECT
    dp.state_desc + ' ' 
       + dp.permission_name collate latin1_general_cs_as
       + ISNULL((' ON ' + QUOTENAME(s.name) + '.' + QUOTENAME(o.name)),'')
       + ' TO ' + QUOTENAME(dpr.name)
FROM sys.database_permissions AS dp
  LEFT JOIN sys.objects AS o ON dp.major_id=o.object_id
  LEFT JOIN sys.schemas AS s ON o.schema_id = s.schema_id
  LEFT JOIN sys.database_principals AS dpr ON dp.grantee_principal_id=dpr.principal_id
WHERE dpr.name NOT IN ('public','guest')

Slight change of the accepted answer if you want to grab permissions that are applied at database level in addition to object level. Basically switch to LEFT JOIN and make sure to handle NULL for object and schema names.

You can have it this way:

It is important to mind the commas after each struct item or set of items.

earnings := []LineItemsType{

        LineItemsType{

            TypeName: "Earnings",

            Totals: 0.0,

            HasTotal: true,

            items: []LineItems{

                LineItems{

                    name: "Basic Pay",

                    amount: 100.0,
                },

                LineItems{

                    name: "Commuter Allowance",

                    amount: 100.0,
                },
            },
        },
        LineItemsType{

            TypeName: "Earnings",

            Totals: 0.0,

            HasTotal: true,

            items: []LineItems{

                LineItems{

                    name: "Basic Pay",

                    amount: 100.0,
                },

                LineItems{

                    name: "Commuter Allowance",

                    amount: 100.0,
                },
            },
        },
    }

Simply do this:

IF EXISTS (SELECT * FROM tablename)
BEGIN
    DELETE from  tablename
    DBCC checkident ('tablename', reseed, 0)
END

Please refer to the following method. It takes your date String as argument1, you need to specify the existing format of the date as argument2, and the result (expected) format as argument 3.

Refer to this link to understand various formats: Available Date Formats

public static String formatDateFromOnetoAnother(String date,String givenformat,String resultformat) {

    String result = "";
    SimpleDateFormat sdf;
    SimpleDateFormat sdf1;

    try {
        sdf = new SimpleDateFormat(givenformat);
        sdf1 = new SimpleDateFormat(resultformat);
        result = sdf1.format(sdf.parse(date));
    }
    catch(Exception e) {
        e.printStackTrace();
        return "";
    }
    finally {
        sdf=null;
        sdf1=null;
    }
    return result;
}

This just worked for me:

I was trying to leave a space in the Apple Pages new LaTeX input area. I typed the following and it left a clean line.

\mbox{\phantom{0}}\\

I think you are talking about padding strings with spaces.

One way to do this is with string format codes.

For example, if you want to pad a string to a certain length with spaces, use something like this:

String padded = String.format("%-20s", str);

In a formatter, % introduces a format sequence. The - means that the string will be left-justified (spaces will be added on the right of the string). The 20 means the resulting string will be 20 characters long. The s is the character string format code, and ends the format sequence.

The accepted answer which was triggering input event with jQuery didn't work for me. Creating an event and dispatching with native JavaScript did the trick.

$("input")[0].dispatchEvent(new Event("input", { bubbles: true }));

You can try this :

To open Gallery :

private void browseImage() {

        try {
  Intent galleryIntent = new Intent(Intent.ACTION_PICK,
                    android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
  startActivityForResult(galleryIntent, GALLERY_IMAGE_PICK); //GALLERY_IMAGE_PICK it is a string
  } catch (Exception e) {}
     }

To open Camera :

 private void captureImage() {
    Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

    fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE);

    intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);

    // start the image capture Intent

    startActivityForResult(intent, CAMERA_CAPTURE_IMAGE_REQUEST_CODE);

}

From plt.imshow() official guide, we know that aspect controls the aspect ratio of the axes. Well in my words, the aspect is exactly the ratio of x unit and y unit. Most of the time we want to keep it as 1 since we do not want to distort out figures unintentionally. However, there is indeed cases that we need to specify aspect a value other than 1. The questioner provided a good example that x and y axis may have different physical units. Let's assume that x is in km and y in m. Hence for a 10x10 data, the extent should be [0,10km,0,10m] = [0, 10000m, 0, 10m]. In such case, if we continue to use the default aspect=1, the quality of the figure is really bad. We can hence specify aspect = 1000 to optimize our figure. The following codes illustrate this method.

%matplotlib inline
import numpy as np
import matplotlib.pyplot as plt
rng=np.random.RandomState(0)
data=rng.randn(10,10)
plt.imshow(data, origin = 'lower',  extent = [0, 10000, 0, 10], aspect = 1000)

Nevertheless, I think there is an alternative that can meet the questioner's demand. We can just set the extent as [0,10,0,10] and add additional xy axis labels to denote the units. Codes as follows.

plt.imshow(data, origin = 'lower',  extent = [0, 10, 0, 10])
plt.xlabel('km')
plt.ylabel('m')

To make a correct figure, we should always bear in mind that x_max-x_min = x_res * data.shape[1] and y_max - y_min = y_res * data.shape[0], where extent = [x_min, x_max, y_min, y_max]. By default, aspect = 1, meaning that the unit pixel is square. This default behavior also works fine for x_res and y_res that have different values. Extending the previous example, let's assume that x_res is 1.5 while y_res is 1. Hence extent should equal to [0,15,0,10]. Using the default aspect, we can have rectangular color pixels, whereas the unit pixel is still square!

plt.imshow(data, origin = 'lower',  extent = [0, 15, 0, 10])
# Or we have similar x_max and y_max but different data.shape, leading to different color pixel res.
data=rng.randn(10,5)
plt.imshow(data, origin = 'lower',  extent = [0, 5, 0, 5])

The aspect of color pixel is x_res / y_res. setting its aspect to the aspect of unit pixel (i.e. aspect = x_res / y_res = ((x_max - x_min) / data.shape[1]) / ((y_max - y_min) / data.shape[0])) would always give square color pixel. We can change aspect = 1.5 so that x-axis unit is 1.5 times y-axis unit, leading to a square color pixel and square whole figure but rectangular pixel unit. Apparently, it is not normally accepted.

data=rng.randn(10,10)
plt.imshow(data, origin = 'lower',  extent = [0, 15, 0, 10], aspect = 1.5)

The most undesired case is that set aspect an arbitrary value, like 1.2, which will lead to neither square unit pixels nor square color pixels.

plt.imshow(data, origin = 'lower',  extent = [0, 15, 0, 10], aspect = 1.2)

Long story short, it is always enough to set the correct extent and let the matplotlib do the remaining things for us (even though x_res!=y_res)! Change aspect only when it is a must.

Read Byte by Byte and check that each byte against '\n' if it is not, then store it into buffer
if it is '\n' add '\0' to buffer and then use atoi()

You can read a single byte like this

char c;
read(fd,&c,1);

See read()
