Well, if you can use Tcl/Tk in your environment, you probably should write a TCL script and use that. You might also look at wish.

root.configure(background='black')

or more generally

<widget>.configure(background='black')

This is the easiest solution if you have multiple files and do not want to type in the names one by one:

qpdf --empty --pages *.pdf -- out.pdf

Modification to the answer by Justin that works for me:

1. Added img.onload
2. Expand the POST request with a real example

function handleFiles()
{
    var dataurl = null;
    var filesToUpload = document.getElementById('photo').files;
    var file = filesToUpload[0];

    // Create an image
    var img = document.createElement("img");
    // Create a file reader
    var reader = new FileReader();
    // Set the image once loaded into file reader
    reader.onload = function(e)
    {
        img.src = e.target.result;

        img.onload = function () {
            var canvas = document.createElement("canvas");
            var ctx = canvas.getContext("2d");
            ctx.drawImage(img, 0, 0);

            var MAX_WIDTH = 800;
            var MAX_HEIGHT = 600;
            var width = img.width;
            var height = img.height;

            if (width > height) {
              if (width > MAX_WIDTH) {
                height *= MAX_WIDTH / width;
                width = MAX_WIDTH;
              }
            } else {
              if (height > MAX_HEIGHT) {
                width *= MAX_HEIGHT / height;
                height = MAX_HEIGHT;
              }
            }
            canvas.width = width;
            canvas.height = height;
            var ctx = canvas.getContext("2d");
            ctx.drawImage(img, 0, 0, width, height);

            dataurl = canvas.toDataURL("image/jpeg");

            // Post the data
            var fd = new FormData();
            fd.append("name", "some_filename.jpg");
            fd.append("image", dataurl);
            fd.append("info", "lah_de_dah");
            $.ajax({
                url: '/ajax_photo',
                data: fd,
                cache: false,
                contentType: false,
                processData: false,
                type: 'POST',
                success: function(data){
                    $('#form_photo')[0].reset();
                    location.reload();
                }
            });
        } // img.onload
    }
    // Load files into file reader
    reader.readAsDataURL(file);
}

1 - Open Eclipse IDE. 2 - Press: Alt + H 3 - Use keyboard arrows to go dwn the list 4 - Select About Eclipse IDE tab.

You have the pipe the other way around and you need to echo the query, like this:

myvariable=$(echo "SELECT A, B, C FROM table_a" | mysql db -u $user -p $password)

Another alternative is to use only the mysql client, like this

myvariable=$(mysql db -u $user -p $password -se "SELECT A, B, C FROM table_a")

(-s is required to avoid the ASCII-art)

Now, BASH isn't the most appropriate language to handle this type of scenarios, especially handling strings and splitting SQL results and the like. You have to work a lot to get things that would be very, very simple in Perl, Python or PHP.

For example, how will you get each of A, B and C on their own variable? It's certainly doable, but if you do not understand pipes and echo (very basic shell stuff), it will not be an easy task for you to do, so if at all possible I'd use a better suited language.

I have done a microbenchmark (JMH) to compare Moneta (java currency JSR 354 implementation) against BigDecimal in terms of performance.

Surprisingly, BigDecimal performance seems to be better than moneta's. I have used following moneta config:

Please feel free to correct me if i'm missing something

In this case, it doesn't matter as there is no content between the two divs.

Either one will get the browser to scroll down to it.

The a element will look like:

<a href="mypageName.html#buttonOne">buttonOne</a>

Or:

<a href="mypageName.html#linkedinB">linkedinB</a>

This is one example where using prepared statements really saves you some trouble.

In MySQL, in order to insert a null value, you must specify it at INSERT time or leave the field out which requires additional branching:

INSERT INTO table2 (f1, f2)
  VALUES ('String Value', NULL);

However, if you want to insert a value in that field, you must now branch your code to add the single quotes:

INSERT INTO table2 (f1, f2)
  VALUES ('String Value', 'String Value');

Prepared statements automatically do that for you. They know the difference between string(0) "" and null and write your query appropriately:

$stmt = $mysqli->prepare("INSERT INTO table2 (f1, f2) VALUES (?, ?)");
$stmt->bind_param('ss', $field1, $field2);

$field1 = "String Value";
$field2 = null;

$stmt->execute();

It escapes your fields for you, makes sure that you don't forget to bind a parameter. There is no reason to stay with the mysql extension. Use mysqli and it's prepared statements instead. You'll save yourself a world of pain.

You can use link_to_function (removed in Rails 4.1):

link_to_function 'My link with obtrusive JavaScript', 'alert("Oh no!")'

Or, if you absolutely need to use link_to:

link_to 'Another link with obtrusive JavaScript', '#',
        :onclick => 'alert("Please no!")'

However, putting JavaScript right into your generated HTML is obtrusive, and is bad practice.

Instead, your Rails code should simply be something like this:

link_to 'Link with unobtrusive JavaScript',
        '/actual/url/in/case/javascript/is/broken',
        :id => 'my-link'

And assuming you're using the Prototype JS framework, JS like this in your application.js:

$('my-link').observe('click', function (event) {
  alert('Hooray!');
  event.stop(); // Prevent link from following through to its given href
});

Or if you're using jQuery:

$('#my-link').click(function (event) {
  alert('Hooray!');
  event.preventDefault(); // Prevent link from following its href
});

By using this third technique, you guarantee that the link will follow through to some other page—not just fail silently—if JavaScript is unavailable for the user. Remember, JS could be unavailable because the user has a poor internet connection (e.g., mobile device, public wifi), the user or user's sysadmin disabled it, or an unexpected JS error occurred (i.e., developer error).

An Iterator moves forward only, if it read it once, it's done. Your

m.get(itr2.next());

is reading the next value of itr2.next();, that is why you are missing a few (actually not a few, every other) keys.

We can solve this by using modulus operator (%)

26 % 7 = 5;

but 26 / 7 = 3 because it will give quotient but % operator will give remainder.

The answers that have been given so far will only work the first time that the ng-repeat gets rendered, but if you have a dynamic ng-repeat, meaning that you are going to be adding/deleting/filtering items, and you need to be notified every time that the ng-repeat gets rendered, those solutions won't work for you.

So, if you need to be notified EVERY TIME that the ng-repeat gets re-rendered and not just the first time, I've found a way to do that, it's quite 'hacky', but it will work fine if you know what you are doing. Use this $filter in your ng-repeat before you use any other $filter:

.filter('ngRepeatFinish', function($timeout){
    return function(data){
        var me = this;
        var flagProperty = '__finishedRendering__';
        if(!data[flagProperty]){
            Object.defineProperty(
                data, 
                flagProperty, 
                {enumerable:false, configurable:true, writable: false, value:{}});
            $timeout(function(){
                    delete data[flagProperty];                        
                    me.$emit('ngRepeatFinished');
                },0,false);                
        }
        return data;
    };
})

This will $emit an event called ngRepeatFinished every time that the ng-repeat gets rendered.

How to use it:

<li ng-repeat="item in (items|ngRepeatFinish) | filter:{name:namedFiltered}" >

The ngRepeatFinish filter needs to be applied directly to an Array or an Object defined in your $scope, you can apply other filters after.

How NOT to use it:

<li ng-repeat="item in (items | filter:{name:namedFiltered}) | ngRepeatFinish" >

Do not apply other filters first and then apply the ngRepeatFinish filter.

When should I use this?

If you want to apply certain css styles into the DOM after the list has finished rendering, because you need to have into account the new dimensions of the DOM elements that have been re-rendered by the ng-repeat. (BTW: those kind of operations should be done inside a directive)

What NOT TO DO in the function that handles the ngRepeatFinished event:

• Do not perform a $scope.$apply in that function or you will put Angular in an endless loop that Angular won't be able to detect.

• Do not use it for making changes in the $scope properties, because those changes won't be reflected in your view until the next $digest loop, and since you can't perform an $scope.$apply they won't be of any use.

"But filters are not meant to be used like that!!"

No, they are not, this is a hack, if you don't like it don't use it. If you know a better way to accomplish the same thing please let me know it.

Summarizing

This is a hack, and using it in the wrong way is dangerous, use it only for applying styles after the ng-repeat has finished rendering and you shouldn't have any issues.

I found the solution thanks to the link in Vincent's answer.

This post is now nearly 5 years old! Python-2.7 will stop receiving official updates from python.org in 2020. Also, Python-3.7 has been released. Check out Python-Future on how to make your Python-2 code compatible with Python-3. For updating conda, the documentation now recommends using conda update --all in each of your conda environments to update all packages and the Python executable for that version. Also, since they changed their name to Anaconda, I don't know if the Windows registry keys are still the same.

There have been no updates to Python(x,y) since June of 2015, so I think it's safe to assume it has been abandoned.

As @cxw comments below, these answers are for the same bit-versions, and by bit-version I mean 64-bit vs. 32-bit. For example, these answers would apply to updating from 64-bit Python-2.7.10 to 64-bit Python-2.7.11, ie: the same bit-version. While it is possible to install two different bit versions of Python together, it would require some hacking, so I'll save that exercise for the reader. If you don't want to hack, I suggest that if switching bit-versions, remove the other bit-version first.

• Anaconda and MiniConda can be used with an existing Python installation by disabling the options to alter the Windows PATH and Registry. After extraction, create a symlink to conda in your bin or install conda from PyPI. Then create another symlink called conda-activate to activate in the Anaconda/Miniconda root bin folder. Now Anaconda/Miniconda is just like Ruby RVM. Just use conda-activate root to enable Anaconda/Miniconda.
• Portable Python is no longer being developed or maintained.

TL;DR

• Using Anaconda or miniconda, then just execute conda update --all to keep each conda environment updated,
• same major version of official Python (e.g. 2.7.5), just install over old (e.g. 2.7.4),
• different major version of official Python (e.g. 3.3), install side-by-side with old, set paths/associations to point to dominant (e.g. 2.7), shortcut to other (e.g. in BASH $ ln /c/Python33/python.exe python3).

The answer depends:

1. If OP has 2.7.x and wants to install newer version of 2.7.x, then

   • if using MSI installer from the official Python website, just install over old version, installer will issue warning that it will remove and replace the older version; looking in "installed programs" in "control panel" before and after confirms that the old version has been replaced by the new version; newer versions of 2.7.x are backwards compatible so this is completely safe and therefore IMHO multiple versions of 2.7.x should never necessary.
   • if building from source, then you should probably build in a fresh, clean directory, and then point your path to the new build once it passes all tests and you are confident that it has been built successfully, but you may wish to keep the old build around because building from source may occasionally have issues. See my guide for building Python x64 on Windows 7 with SDK 7.0.
   • if installing from a distribution such as Python(x,y), see their website. Python(x,y) has been abandoned. I believe that updates can be handled from within Python(x,y) with their package manager, but updates are also included on their website. I could not find a specific reference so perhaps someone else can speak to this. Similar to ActiveState and probably Enthought, Python (x,y) clearly states it is incompatible with other installations of Python:

     It is recommended to uninstall any other Python distribution before installing Python(x,y)

   • Enthought Canopy uses an MSI and will install either into Program Files\Enthought or home\AppData\Local\Enthought\Canopy\App for all users or per user respectively. Newer installations are updated by using the built in update tool. See their documentation.
   • ActiveState also uses an MSI so newer installations can be installed on top of older ones. See their installation notes.

     Other Python 2.7 Installations On Windows, ActivePython 2.7 cannot coexist with other Python 2.7 installations (for example, a Python 2.7 build from python.org). Uninstall any other Python 2.7 installations before installing ActivePython 2.7.

   • Sage recommends that you install it into a virtual machine, and provides a Oracle VirtualBox image file that can be used for this purpose. Upgrades are handled internally by issuing the sage -upgrade command.

   • Anaconda can be updated by using the conda command:

     conda update --all
     

     Anaconda/Miniconda lets users create environments to manage multiple Python versions including Python-2.6, 2.7, 3.3, 3.4 and 3.5. The root Anaconda/Miniconda installations are currently based on either Python-2.7 or Python-3.5.

     Anaconda will likely disrupt any other Python installations. Installation uses MSI installer. [UPDATE: 2016-05-16] Anaconda and Miniconda now use .exe installers and provide options to disable Windows PATH and Registry alterations.

     Therefore Anaconda/Miniconda can be installed without disrupting existing Python installations depending on how it was installed and the options that were selected during installation. If the .exe installer is used and the options to alter Windows PATH and Registry are not disabled, then any previous Python installations will be disabled, but simply uninstalling the Anaconda/Miniconda installation should restore the original Python installation, except maybe the Windows Registry Python\PythonCore keys.

     Anaconda/Miniconda makes the following registry edits regardless of the installation options: HKCU\Software\Python\ContinuumAnalytics\ with the following keys: Help, InstallPath, Modules and PythonPath - official Python registers these keys too, but under Python\PythonCore. Also uninstallation info is registered for Anaconda\Miniconda. Unless you select the "Register with Windows" option during installation, it doesn't create PythonCore, so integrations like Python Tools for Visual Studio do not automatically see Anaconda/Miniconda. If the option to register Anaconda/Miniconda is enabled, then I think your existing Python Windows Registry keys will be altered and uninstallation will probably not restore them.

   • WinPython updates, I think, can be handled through the WinPython Control Panel.
   • PortablePython is no longer being developed. It had no update method. Possibly updates could be unzipped into a fresh directory and then App\lib\site-packages and App\Scripts could be copied to the new installation, but if this didn't work then reinstalling all packages might have been necessary. Use pip list to see what packages were installed and their versions. Some were installed by PortablePython. Use easy_install pip to install pip if it wasn't installed.

2. If OP has 2.7.x and wants to install a different version, e.g. <=2.6.x or >=3.x.x, then installing different versions side-by-side is fine. You must choose which version of Python (if any) to associate with *.py files and which you want on your path, although you should be able to set up shells with different paths if you use BASH. AFAIK 2.7.x is backwards compatible with 2.6.x, so IMHO side-by-side installs is not necessary, however Python-3.x.x is not backwards compatible, so my recommendation would be to put Python-2.7 on your path and have Python-3 be an optional version by creating a shortcut to its executable called python3 (this is a common setup on Linux). The official Python default install path on Windows is

   • C:\Python33 for 3.3.x (latest 2013-07-29)
   • C:\Python32 for 3.2.x
   • &c.
   • C:\Python27 for 2.7.x (latest 2013-07-29)
   • C:\Python26 for 2.6.x
   • &c.

3. If OP is not updating Python, but merely updating packages, they may wish to look into virtualenv to keep the different versions of packages specific to their development projects separate. Pip is also a great tool to update packages. If packages use binary installers I usually uninstall the old package before installing the new one.

I hope this clears up any confusion.

some people talk very well about PyInstaller

http://www.pyinstaller.org/

Add the following to package.json:

  "engines": {
    "node": ">=10.0.0",
    "npm": ">=6.0.0"
  },

Add the following to .npmrc (same directory as package.json):

engine-strict=true

All are good answers explaining why you cannot modify string literals because they are placed in read-only memory. However, when push comes to shove, there is a way to do this. Check out this example:

#include <sys/mman.h>
#include <unistd.h>
#include <stddef.h>
#include <string.h>
#include <stdlib.h>
#include <stdio.h>

int take_me_back_to_DOS_times(const void *ptr, size_t len);

int main()

    return 0;

I have written this as part of my somewhat deeper thoughts on const-correctness, which you might find interesting (I hope :)).

Hope it helps. Good Luck!

dropdowns always show up on top, only solution for this problem is to hide dropdowns when image is displayed (display:block or visibility:visibile) and show them when image hidden (display:none or visibility:hidden)

Trying with a different version of gcc worked for me - gcc 4.9 in my case.

While I tried the approach above, it becomes a complete disaster with mvc. Your controller passing a model and your view using a strongly typed model become too difficult to work with.

Get your Dataset into a List ..... I have a repository pattern and here is an example of getting a dataset from an old school asmx web service private readonly CISOnlineSRVDEV.ServiceSoapClient _ServiceSoapClient;

    public Get_Client_Repository()
        : this(new CISOnlineSRVDEV.ServiceSoapClient())
    {

    }
    public Get_Client_Repository(CISOnlineSRVDEV.ServiceSoapClient serviceSoapClient)
    {
        _ServiceSoapClient = serviceSoapClient;
    }


    public IEnumerable<IClient> GetClient(IClient client)
    {
        // ****  Calling teh web service with passing in the clientId and returning a dataset
        DataSet dataSet = _ServiceSoapClient.get_clients(client.RbhaId,
                                                        client.ClientId,
                                                        client.AhcccsId,
                                                        client.LastName,
                                                        client.FirstName,
                                                        "");//client.BirthDate.ToString());  //TODO: NEED TO FIX

        // USE LINQ to go through the dataset to make it easily available for the Model to display on the View page
        List<IClient> clients = (from c in dataSet.Tables[0].AsEnumerable()
                                 select new Client()
                                 {
                                     RbhaId = c[5].ToString(),
                                     ClientId = c[2].ToString(),
                                     AhcccsId = c[6].ToString(),
                                     LastName = c[0].ToString(), // Add another field called   Sex M/F  c[4]
                                     FirstName = c[1].ToString(),
                                     BirthDate = c[3].ToDateTime()  //extension helper  ToDateTime()
                                 }).ToList<IClient>();

        return clients;

    }

Then in the Controller I'm doing this

IClient client = (IClient)TempData["Client"];

// Instantiate and instance of the repository 
var repository = new Get_Client_Repository();
// Set a model object to return the dynamic list from repository method call passing in the parameter data
var model = repository.GetClient(client);

// Call the View up passing in the data from the list
return View(model);

Then in the View it is easy :

@model IEnumerable<CISOnlineMVC.DAL.IClient>

@{
    ViewBag.Title = "CLIENT ALL INFORMATION";
}

<h2>CLIENT ALL INFORMATION</h2>

<table>
    <tr>
        <th></th>
        <th>Last Name</th>
        <th>First Name</th>
        <th>Client ID</th>
        <th>DOB</th>
        <th>Gender</th>
        <th>RBHA ID</th>
        <th>AHCCCS ID</th>
    </tr>

@foreach (var item in Model) {
    <tr>
        <td>
            @Html.ActionLink("Select", "ClientDetails", "Cis", new { id = item.ClientId }, null) |
        </td>
        <td>
            @item.LastName
        </td>
        <td>
            @item.FirstName
        </td>
         <td>
            @item.ClientId
        </td>
         <td>
            @item.BirthDate
        </td>
         <td>
            Gender @* ADD in*@
        </td>
         <td>
            @item.RbhaId
        </td>
         <td>
            @item.AhcccsId
        </td>
    </tr>
}

</table>

The same problem Error while retrieving information from server. [RPC:S-5:AEC-0] was resolved after these steps:

1. Change password of your Google account via web.
2. Wait for a Sign-in error notification on your device.
3. Type new password and problem should disappeared.

Actually, this helps me.

list.append returns None, since it is an in-place operation and you are assigning it back to dates_dict[key]. So, the next time when you do dates_dict.get(key, []).append you are actually doing None.append. That is why it is failing. Instead, you can simply do

dates_dict.setdefault(key, []).append(date)

But, we have collections.defaultdict for this purpose only. You can do something like this

from collections import defaultdict
dates_dict = defaultdict(list)
for key, date in cur:
    dates_dict[key].append(date)

This will create a new list object, if the key is not found in the dictionary.

Note: Since the defaultdict will create a new list if the key is not found in the dictionary, this will have unintented side-effects. For example, if you simply want to retrieve a value for the key, which is not there, it will create a new list and return it.

cell.setCellType(Cell.CELL_TYPE_STRING); is working fine for me

Here's a way to do it:

// The method to call
void Foo()
{
}


Action action = Foo;
action.BeginInvoke(ar => action.EndInvoke(ar), null);

Of course you need to replace Action by another type of delegate if the method has a different signature

Global Gzip in HttpModule

If you don't have access to shared hosting - the final IIS instance. You can create a HttpModule that gets added this code to every HttpApplication.Begin_Request event:-

HttpContext context = HttpContext.Current;
context.Response.Filter = new GZipStream(context.Response.Filter, CompressionMode.Compress);
HttpContext.Current.Response.AppendHeader("Content-encoding", "gzip");
HttpContext.Current.Response.Cache.VaryByHeaders["Accept-encoding"] = true;

Take a look at this site, it explains two methods for reading from console in java, using Scanner or the classical InputStreamReader from System.in.

Following code is taken from cited website:

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class ReadConsoleSystem {
  public static void main(String[] args) {

    System.out.println("Enter something here : ");

    try{
        BufferedReader bufferRead = new BufferedReader(new InputStreamReader(System.in));
        String s = bufferRead.readLine();

        System.out.println(s);
    }
    catch(IOException e)
    {
        e.printStackTrace();
    }

  }
}

--

import java.util.Scanner;

public class ReadConsoleScanner {
  public static void main(String[] args) {

      System.out.println("Enter something here : ");

       String sWhatever;

       Scanner scanIn = new Scanner(System.in);
       sWhatever = scanIn.nextLine();

       scanIn.close();            
       System.out.println(sWhatever);
  }
}

Regards.

EDIT: Thanks for the comments - I looked it up in the C99 standard, which says in section 6.5.3.4:

The value of the result is implementation-defined, and its type (an unsigned integer type) is size_t, defined in <stddef.h> (and other headers)

So, the size of size_t is not specified, only that it has to be an unsigned integer type. However, an interesting specification can be found in chapter 7.18.3 of the standard:

limit of size_t

SIZE_MAX 65535

Which basically means that, irrespective of the size of size_t, the allowed value range is from 0-65535, the rest is implementation dependent.

This is just an example how to use it in a unit test that I hacked to debug this issue. The key ingredients are

• mapper.registerModule(new JavaTimeModule());
• maven dependency of <artifactId>jackson-datatype-jsr310</artifactId>

Code:

import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.datatype.jsr310.JavaTimeModule;
import org.testng.Assert;
import org.testng.annotations.Test;

import java.io.IOException;
import java.io.Serializable;
import java.time.Instant;

class Mumu implements Serializable {
    private Instant from;
    private String text;

    Mumu(Instant from, String text) {
        this.from = from;
        this.text = text;
    }

    public Mumu() {
    }

    public Instant getFrom() {
        return from;
    }

    public String getText() {
        return text;
    }

    @Override
    public String toString() {
        return "Mumu{" +
                "from=" + from +
                ", text='" + text + '\'' +
                '}';
    }
}
public class Scratch {


    @Test
    public void JacksonInstant() throws IOException {
        ObjectMapper mapper = new ObjectMapper();
        mapper.registerModule(new JavaTimeModule());

        Mumu before = new Mumu(Instant.now(), "before");
        String jsonInString = mapper.writeValueAsString(before);


        System.out.println("-- BEFORE --");
        System.out.println(before);
        System.out.println(jsonInString);

        Mumu after = mapper.readValue(jsonInString, Mumu.class);
        System.out.println("-- AFTER --");
        System.out.println(after);

        Assert.assertEquals(after.toString(), before.toString());
    }

}

Other answers already on Stackoverflow:

• How do I install modules locally without root access...
• How can I use a new Perl module without install permissions?

From perlfaq8:

When you build modules, tell Perl where to install the modules.

For Makefile.PL-based distributions, use the INSTALL_BASE option when generating Makefiles:

perl Makefile.PL INSTALL_BASE=/mydir/perl

You can set this in your CPAN.pm configuration so modules automatically install in your private library directory when you use the CPAN.pm shell:

% cpan
cpan> o conf makepl_arg INSTALL_BASE=/mydir/perl
cpan> o conf commit

For Build.PL-based distributions, use the --install_base option:

perl Build.PL --install_base /mydir/perl

You can configure CPAN.pm to automatically use this option too:

% cpan
cpan> o conf mbuildpl_arg '--install_base /mydir/perl'
cpan> o conf commit

You may get more success if you do a "search" for the runtime env from the preferences screen instead of hitting "add" - see this demo on youtube. http://www.youtube.com/watch?v=EOkN5IPoJVs&playnext_from=TL&videos=rVnITzSU2Z8 - When you hit search, you are prompted to point to the tomcat directory and then it SHOULD add it as a server runtime environment. Unfortunately for me, that is not the case (I get "no new server runtime environments were found") But you might have more success.

Try this

<script type="text/javascript" src="//www.google.com/recaptcha/api/js/recaptcha_ajax.js"></script>
<script type="text/javascript">
          function showRecaptcha() {
            Recaptcha.create("YOURPUBLICKEY", 'captchadiv', {
              theme: 'red',
              callback: Recaptcha.focus_response_field
            });
          }
 </script>

<div id="captchadiv"></div>

If you calll showRecaptcha the captchadiv will be populated with a new recaptcha instance.

Note: keyCode is becoming deprecated, use key instead.

function keyPress (e) {
    if(e.key === "Escape") {
        // write your logic here.
    }
}

Code Snippet:

var msg = document.getElementById('state-msg');

document.body.addEventListener('keypress', function(e) {
  if (e.key == "Escape") {
    msg.textContent += 'Escape pressed:'
  }
});

Press ESC key <span id="state-msg"></span>

keyCode is becoming deprecated

It seems keydown and keyup work, even though keypress may not

$(document).keyup(function(e) {
     if (e.key === "Escape") { // escape key maps to keycode `27`
        // <DO YOUR WORK HERE>
    }
});

Which keycode for escape key with jQuery

Study up on multidimensional arrays. This question might help.

The other answer below by Eric is wrong. The namespace declaration he mentioned had nothing to do with the problem.

The real reason it doesn't work is due to security concerns (cf. issue 4197, issue 111905).

Imagine this scenario:

1. You receive an email message from an attacker containing a web page as an attachment, which you download.

2. You open the now-local web page in your browser.

3. The local web page creates an <iframe> whose source is https://mail.google.com/mail/.

4. Because you are logged in to Gmail, the frame loads the messages in your inbox.

5. The local web page reads the contents of the frame by using JavaScript to access frames[0].document.documentElement.innerHTML. (An online web page would not be able to perform this step because it would come from a non-Gmail origin; the same-origin policy would cause the read to fail.)

6. The local web page places the contents of your inbox into a <textarea> and submits the data via a form POST to the attacker's web server. Now the attacker has your inbox, which may be useful for spamming or identify theft.

Chrome foils the above scenario by putting restrictions on local files opened using Chrome. To overcome these restrictions, we've got two solutions:

1. Try running Chrome with the --allow-file-access-from-files flag. I've not tested this myself, but if it works, your system will now also be vulnerable to scenarios of the kind mentioned above.

2. Upload it to a host, and problem solved.

Cprcrack's answer works very well for API levels 19 and under. Just a minor addition to cprcrack's onShowCustomView will get it working on API level 21+

if (Build.VERSION.SDK_INT >= 21) {
      videoViewContainer.setBackgroundColor(Color.BLACK);
      ((ViewGroup) webView.getParent()).addView(videoViewContainer);
      webView.scrollTo(0,0);  // centers full screen view 
} else {
      activityNonVideoView.setVisibility(View.INVISIBLE);
      ViewGroup.LayoutParams vg = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,
                    ViewGroup.LayoutParams.MATCH_PARENT);
      activityVideoView.addView(videoViewContainer,vg);
      activityVideoView.setVisibility(View.VISIBLE);
}

You will also need to reflect the changes in onHideCustomView

If you know there are three li's in the list you're looking at, for example, you could do this:

li + li + li { /* Selects third to last li */
}

In IE6 you can use expressions:

li {
    color: expression(this.previousSibling ? 'red' : 'green'); /* 'green' if last child */
}

I would recommend using a specialized class or Javascript (not IE6 expressions), though, until the :last-child selector gets better support.

I got it from jQuery Plugin Boilerplate

Also described in jQuery Plugin Boilerplate, reprise

// jQuery Plugin Boilerplate
// A boilerplate for jumpstarting jQuery plugins development
// version 1.1, May 14th, 2011
// by Stefan Gabos

// remember to change every instance of "pluginName" to the name of your plugin!
(function($) {

    // here we go!
    $.pluginName = function(element, options) {

    // plugin's default options
    // this is private property and is accessible only from inside the plugin
    var defaults = {

        foo: 'bar',

        // if your plugin is event-driven, you may provide callback capabilities
        // for its events. execute these functions before or after events of your
        // plugin, so that users may customize those particular events without
        // changing the plugin's code
        onFoo: function() {}

    }

    // to avoid confusions, use "plugin" to reference the
    // current instance of the object
    var plugin = this;

    // this will hold the merged default, and user-provided options
    // plugin's properties will be available through this object like:

You can apply a theme to any activity by including android:theme inside <activity> inside manifest file.

For example:

1. <activity android:theme="@android:style/Theme.Dialog">
2. <activity android:theme="@style/CustomTheme">

And if you want to set theme programatically then use setTheme() before calling setContentView() and super.onCreate() method inside onCreate() method.

Use sum() in place of count()

Try below:

SELECT
    ccc_news . * , 
    SUM(if(ccc_news_comments.id = 'approved', 1, 0)) AS comments
FROM
    ccc_news
    LEFT JOIN
        ccc_news_comments
    ON
        ccc_news_comments.news_id = ccc_news.news_id
WHERE
    `ccc_news`.`category` = 'news_layer2'
    AND `ccc_news`.`status` = 'Active'
GROUP BY
    ccc_news.news_id
ORDER BY
    ccc_news.set_order ASC
LIMIT 20 

As many people here have pointed out, arrays in C#, as well as in most other common languages, are statically sized. If you're looking for something more like PHP's arrays, which I'm just going to guess you are, since it's a popular language with dynamically sized (and typed!) arrays, you should use an ArrayList:

var mahByteArray = new ArrayList<byte>();

If you have a byte array from elsewhere, you can use the AddRange function.

mahByteArray.AddRange(mahOldByteArray);

Then you can use Add() and Insert() to add elements.

mahByteArray.Add(0x00); // Adds 0x00 to the end.
mahByteArray.Insert(0, 0xCA) // Adds 0xCA to the beginning.

Need it back in an array? .ToArray() has you covered!

mahOldByteArray = mahByteArray.ToArray();

A solution using java.util.regex.Pattern / java.util.regex.Matcher

String test = "foo bar baz ";
Pattern pattern = Pattern.compile(" ");
Matcher matcher = pattern.matcher(test);
int count = 0;
while (matcher.find()) {
    count++;
}
System.out.println(count);

I think the Class on img tag is better when You use the same style in different structure on Your site. You have to decide when you write less line of CSS code and HTML is more readable.

This might give the increased relevance to the head part that you want. It won't double it, but it might possibly good enough for your sake:

SELECT pages.*,
       MATCH (head, body) AGAINST ('some words') AS relevance,
       MATCH (head) AGAINST ('some words') AS title_relevance
FROM pages
WHERE MATCH (head, body) AGAINST ('some words')
ORDER BY title_relevance DESC, relevance DESC

-- alternatively:
ORDER BY title_relevance + relevance DESC

An alternative that you also want to investigate, if you've the flexibility to switch DB engine, is Postgres. It allows to set the weight of operators and to play around with the ranking.

You could use check constraint with a user defined function to make the check. It is more reliable than a trigger. It can be disabled and reenabled when necessary same as foreign keys and rechecked after a database2 restore.

CREATE FUNCTION dbo.fn_db2_schema2_tb_A
(@column1 INT) 
RETURNS BIT
AS
BEGIN
    DECLARE @exists bit = 0
    IF EXISTS (
      SELECT TOP 1 1 FROM DB2.SCHEMA2.tb_A 
      WHERE COLUMN_KEY_1 =  @COLUMN1
    ) BEGIN 
         SET @exists = 1 
      END;
      RETURN @exists
END
GO

ALTER TABLE db1.schema1.tb_S
  ADD CONSTRAINT CHK_S_key_col1_in_db2_schema2_tb_A
    CHECK(dbo.fn_db2_schema2_tb_A(key_col1) = 1)

FWIW, it smells like an error (or at least a potential source of future pain) to be using files from /usr/include when cross-compiling.

Be carefull when you use derived query for batch delete. It isn't what you expect: DeleteExecution

Couple of ways. Firstly, if you're adding a row each time a [de]activation occurs, you can set the column default to GETDATE() and not set the value in the insert. Otherwise,

UPDATE TableName SET [ColumnName] = GETDATE() WHERE UserId = @userId

Your question is not clear: you want to give "checkbox array id" at input and get true/false at output - in this way you will not know which checkbox was checked (as your function name suggest). So below there is my proposition of body of your isCheckedById which on input take checkbox id and on output return true/false (it's very simple but your ID should not be keyword),

this[id].checked

function isCheckedById(id) {
  return this[id].checked;
}



// TEST

function check() {
  console.clear()
  console.log('1',isCheckedById("myCheckbox1"));
  console.log('2',isCheckedById("myCheckbox2"));
  console.log('3',isCheckedById("myCheckbox3"));
}

<label><input id="myCheckbox1" type="checkbox">check 1</label>
<label><input id="myCheckbox2" type="checkbox">check 2</label>
<label><input id="myCheckbox3" type="checkbox">check 3</label>
<!-- label around inputs makes text clickable -->

You can actualy fake the transparency of option DOMElements with the following CSS:

CSS

option { 
    /* Whatever color  you want */
    background-color: #82caff;
}

See Demo

The option tag does not support rgba colors yet.

I had a really good experience with Avaje Ebean when I was writing a medium sized JavaSE application.

It uses standard JPA annotations to define entities, but exposes a much simpler API (No EntityManager or any of that attached/detached entities crap). It also lets you easily use SQL queries or event plain JDBC calls when necessary.

It also has a very nice fluid and type-safe API for queries. You can write things like:

List<Person> boys = Ebean.find(Person.class)
                                  .where()
                                       .eq("gender", "M")
                                       .le("age", 18)
                                  .orderBy("firstName")
                                  .findList();

Here's some code that may help:

ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive");

string serial_number="";

foreach (ManagementObject wmi_HD in searcher.Get())
{
    serial_number = wmi_HD["SerialNumber"].ToString();
}

MessageBox.Show(serial_number);

You can use in-place operator new. This would be a bit horrible, and I'd recommend keeping in a factory.

Car* createCars(unsigned number)
{
    if (number == 0 )
        return 0;
    Car* cars = reinterpret_cast<Car*>(new char[sizeof(Car)* number]);
    for(unsigned carId = 0;
        carId != number;
        ++carId)
    {
        new(cars+carId) Car(carId);
    }
    return cars;
}

And define a corresponding destroy so as to match the new used in this.

Here is what worked for me:

• Open a command prompt
• Type telnet
• Microsoft Telnet>open <host name or IP address><space><port>

It will confirm whether the port is opened.

Just for the record, if you want both (output and operation result) you can do:

output=`ls no_existing_file` ;  result=$?.success?

I think the difference between the two boils down to access. Environment variables are accessible by any process and Java system properties are only accessible by the process they are added to.

Also as Bohemian stated, env variables are set in the OS (however they 'can' be set through Java) and system properties are passed as command line options or set via setProperty().

Let's just say you have 3 buttons:

<input type="button" disabled="disabled" value="hello world">
<input type="button" disabled value="hello world">
<input type="button" value="hello world">

To style the disabled button you can use the following css:

input[type="button"]:disabled{
    color:#000;
}

This will only affect the button which is disabled.

To stop the color changing when hovering you can use this too:

input[type="button"]:disabled:hover{
    color:#000;
}

You can also avoid this by using a css-reset.

I compile Kotlin to byte code and then de-compile that to Java. I compile with the Kotlin compiler and de-compile with cfr.

My project is here.

This allows me to compile this:

package functionsiiiandiiilambdas.functions.p01tailiiirecursive

tailrec fun findFixPoint(x: Double = 1.0): Double =
        if (x == Math.cos(x)) x else findFixPoint(Math.cos(x))

To this:

package functionsiiiandiiilambdas.functions.p01tailiiirecursive;

public final class ExampleKt {
  public static final double findFixPoint(double x) {
    while (x != Math.cos(x)) {
      x = Math.cos(x);
    }
    return x;
  }

  public static /* bridge */ /* synthetic */ double findFixPoint$default(
      double d, int n, Object object) {
    if ((n & 1) != 0) {
      d = 1.0;
    }
    return ExampleKt.findFixPoint(d);
  }
}

java: Java application executor which is associated with a console to display output/errors

javaw: (Java windowed) application executor not associated with console. So no display of output/errors. It can be used to silently push the output/errors to text files. It is mostly used to launch GUI-based applications.

javaws: (Java web start) to download and run the distributed web applications. Again, no console is associated.

All are part of JRE and use the same JVM.

Answer for the "new" and "cool" Microsoft.

Yay, SQL Server driver now under MIT license on

• GitHub: https://github.com/Microsoft/mssql-jdbc
• Maven Central: http://search.maven.org/#search%7Cga%7C1%7Cmssql-jdbc

<dependency>
    <groupId>com.microsoft.sqlserver</groupId>
    <artifactId>mssql-jdbc</artifactId>
    <version>6.1.0.jre8</version>
</dependency>

Answer for the "old" Microsoft:

For my use-case (integration testing) it was sufficient to use a system scope for the JDBC driver's dependency as such:

<dependency>
    <groupId>com.microsoft.sqlserver</groupId>
    <artifactId>sqljdbc4</artifactId>
    <version>3.0</version>
    <scope>system</scope>
    <systemPath>${basedir}/lib/sqljdbc4.jar</systemPath>
    <optional>true</optional>
</dependency>

That way, I could put the JDBC driver into local version control. No need to have each developer manually set stuff up in their own repositories.

I took inspiration from this answer to another Stack Overflow question and I've also blogged about it here.

You can use:

SET PASSWORD FOR 'root' = PASSWORD('elephant7');

or, in latest versions:

SET PASSWORD FOR root = 'elephant7' 

You can also use:

UPDATE user SET password=password('elephant7') WHERE user='root';

but in Mysql 5.7 the field password is no more there, and you have to use:

UPDATE user SET authentication_string=password('elephant7') WHERE user='root';

You can nest table-cell directly within table. You muslt have a table. Starting eith table-row does not work. Try it with this HTML:

<html>
  <head>
    <style type="text/css">
.table {
  display: table;
  width: 100%;
}
.tr {
  display: table-row;
  width: 100%;
}
.td {
  display: table-cell;
}
    </style>
  </head>
  <body>

    <div class="table">
      <div class="tr">
        <div class="td">
          X
        </div>
        <div class="td">
          X
        </div>
        <div class="td">
          X
        </div>
      </div>
    </div>

      <div class="tr">
        <div class="td">
          X
        </div>
        <div class="td">
          X
        </div>
        <div class="td">
          X
        </div>
      </div>

    <div class="table">
        <div class="td">
          X
        </div>
        <div class="td">
          X
        </div>
        <div class="td">

You have to edit httpd.conf and find this line: Listen 127.0.0.1:80

Then write down your desired IP you set for LAN. Don't use automatic IP.
e.g.: Listen 192.168.137.1:80

I used 192.167.137.1 as my LAN IP of Windows 7. Restart Apache and enjoy sharing.

If you are planning a public facing web site then you should not go with either option. Your should use a Content Delivery Network (CDN). There are price, scalability and speed advantages to a CDN when delivering a large amount of static content over the internet.

Checkout this wiki, specifically the section Restrictions on valid host names

Hostnames are composed of series of labels concatenated with dots, as are all domain names. For example, "en.wikipedia.org" is a hostname. Each label must be between 1 and 63 characters long, and the entire hostname (including the delimiting dots but not a trailing dot) has a maximum of 253 ASCII characters.

The Internet standards (Requests for Comments) for protocols mandate that component hostname labels may contain only the ASCII letters 'a' through 'z' (in a case-insensitive manner), the digits '0' through '9', and the hyphen ('-'). The original specification of hostnames in RFC 952, mandated that labels could not start with a digit or with a hyphen, and must not end with a hyphen. However, a subsequent specification (RFC 1123) permitted hostname labels to start with digits. No other symbols, punctuation characters, or white space are permitted.

I had this error aswell.

I am working in mysql workbench. When giving the values they have to be inside "". That solved it for me.

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

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

To get access each item we just do the following:

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

I had a fragment that was getting loaded-in after/by the main partial that came in via routing.

I needed to run a function after that subpartial loaded and I didn't want to write a new directive and figured out you could use a cheeky ngIf

Controller of parent partial:

$scope.subIsLoaded = function() { /*do stuff*/; return true; };

HTML of subpartial

<element ng-if="subIsLoaded()"><!-- more html --></element>

The analytic function approach would look something like

SELECT a, some_date_column
  FROM (SELECT a,
               some_date_column,
               rank() over (partition by a order by some_date_column desc) rnk
          FROM tablename)
 WHERE rnk = 1

Note that depending on how you want to handle ties (or whether ties are possible in your data model), you may want to use either the ROW_NUMBER or the DENSE_RANK analytic function rather than RANK.

This steps are all in the terminal:)->source

1. Step make sure your server is running:

sudo /usr/local/mysql/support-files/mysql.server start

2. Check MySQL version. "This also puts you in to a shell interactive dialogue with mySQL, type q to exit."

/usr/local/mysql/bin/mysql -v

3. Make your life easier: "After installation, in order to use mysql commands without typing the full path to the commands you need to add the mysql directory to your shell path, (optional step) this is done in your “.bash_profile” file in your home directory, if you don’t have that file just create it using vi or nano:"

cd ; nano .bash_profile

paste in and save:

export PATH="/usr/local/mysql/bin:$PATH"

"The first command brings you to your home directory and opens the .bash_profile file or creates a new one if it doesn’t exist, then add in the line above which adds the mysql binary path to commands that you can run. Exit the file with type “control + x” and when prompted save the change by typing “y”. Last thing to do here is to reload the shell for the above to work straight away."

source ~/.bash_profile mysql -v

"You will get the version number again, just type “q” to exit."

4. Check out on which port the server is running:

in your terminal type in: mysql

and then

SHOW GLOBAL VARIABLES LIKE 'PORT';

use everytime a semikolon in the mysql client (shell)!

now you know your port and where you can configure your server(in the terminal with mysql shell/client). but for a successful connection with MySQL Benchmark or an other client you have to know more. username, passwort hostname and port. after the installation the root user has no passwort so set(howtoSetPW) the passwort in terminal with mysql shell/client. and the server is running local. so type in root, yourPW, localhost and 3007. have fun!

You can use both PHP and javascript. Perform your php codes in the backend and redirect to a php page. On the php page you redirected to add the code below:

<?php if(condition_to_check_for){ ?>

    <script type="text/javascript">
       window.open('url_goes_here', '_blank');
    </script>

<?  } ?>

Try this:

#include <windows.h>

int main ()

{
    system ("start notepad.exe") // As an example. Change [notepad] to any executable file //

    return 0 ;
}

Isn't this as simple as adding your git install to your Windows path?

E.g. Win+R rundll32.exe sysdm.cpl,EditEnvironmentVariables Edit...PATH appending your Mysysgit install path e.g. ;C:\Program Files (x86)\Git\bin. Re-run Cygwin and voila. As Cygwin automatically loads in the Windows environment, so too will your native install of Git.

In my case, I have Eclipse Maven project. I had the same issue and I posted detailed explanation of the issue and answer here Eclipse Maven - Code Completion fails "This compilation unit is not on the build path of a Java project" and "Failed to Download Index" Error

It seems you are hitting a UTF-8 byte order mark (BOM). Try using this unicode string with BOM extracted out:

import codecs

content = unicode(q.content.strip(codecs.BOM_UTF8), 'utf-8')
parser.parse(StringIO.StringIO(content))

I used strip instead of lstrip because in your case you had multiple occurences of BOM, possibly due to concatenated file contents.

NaN === NaN;        // false
Number.NaN === NaN; // false
isNaN(NaN);         // true
isNaN(Number.NaN);  // true

Equality operator (== and ===) cannot be used to test a value against NaN.

Look at Mozilla Documentation The global NaN property is a value representing Not-A-Numbe

The best way is using 'isNaN()' which is buit-in function to check NaN. All browsers supports the way..

Wrap the 'child' function(s) being passed as/with arguments within function wrappers to prevent them being evaluated when the 'parent' function is called.

function outcome(){
    return false;
}

function process(callbackSuccess, callbackFailure){
    if ( outcome() )
        callbackSuccess();
    else
        callbackFailure();
}

process(function(){alert("OKAY");},function(){alert("OOPS");})

If you define the method as static you can use it without instantiating the class first, but then you also dont have the object variables available for use.

public class Foo {
   public static String Bar() {
      return "bla";
   }
}

In that case you could call it with Foo.Bar().

The accepted answer works but can got complicated when I wanted to try adding Accept headers. This is what I ended up with. It seems simpler to me so I think I'll stick with it in the future:

client.DefaultRequestHeaders.Add("Accept", "application/*+xml;version=5.1");
client.DefaultRequestHeaders.Add("Authorization", "Basic " + authstring);

If you just need to suspend for testing purpose you current thread execution try this:

function longExecFunc(callback, count) {

    for (var j = 0; j < count; j++) {
        for (var i = 1; i < (1 << 30); i++) {
            var q = Math.sqrt(1 << 30);
        }
    }
    callback();
}
longExecFunc(() => { console.log('done!')}, 5); //5, 6 ... whatever. Higher -- longer

Your syntax is incorrect. The var keyword in your for loop must be followed by a variable name, in this case its propName

var propValue;
for(var propName in nyc) {
    propValue = nyc[propName]

    console.log(propName,propValue);
}

I suggest you have a look here for some basics:

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/for...in

You can setup _JAVA_OPTIONS instead of JAVA_OPTS. This should work without $_JAVA_OPTIONS.

In our case, we had dropped support for SSL3, TLS1.0, and TLS1.1 for PCI-DSS compliance on our origin servers. However, you have to manually add support for TLS 1.1+ on your CloudFront origin server config. The AWS console displays the client-to-CF SSL settings, but does not easily show you CF-to-origin settings until you drill down. To fix, in the AWS console under CloudFront:

1. Click DISTRIBUTIONS.
2. Select your distro.
3. Click ORIGINS tab.
4. Select your origin server.
5. Click EDIT.
6. Select all protocols that your origin supports under "Origin SSL Protocols"

I Used Datatable JS plugin for my purpose of exporting an html table data into various formats. With my experience it was very quick, easy to use and configure with minimal coding.

Below is a sample jquery call using datatable plugin, #example is your table id

$(document).ready(function() {
    $('#example').DataTable( {
        dom: 'Bfrtip',
        buttons: [
            'copyHtml5',
            'excelHtml5',
            'csvHtml5',
            'pdfHtml5'
        ]
    } );
} );

Please find the complete example in below datatable reference link :

https://datatables.net/extensions/buttons/examples/html5/simple.html

This is how it looks after configuration( from reference site) :

You need to have following library references in your html ( some can be found in the above reference link)

jquery-1.12.3.js
jquery.dataTables.min.js
dataTables.buttons.min.js
jszip.min.js
pdfmake.min.js
vfs_fonts.js
buttons.html5.min.js

Using comparison operators is way, way faster than calling any function. I'm not 100% sure if this exists, but I think it doesn't.

You can do it like:

change_column :table_name, :column_name, 'integer USING CAST(column_name AS integer)'

or try this:

change_column :table_name, :column_name, :integer, using: 'column_name::integer'

TL;DR;

In most cases, granting access to the following account(s) (one|both) will be enough:

1. IIS AppPool\DefaultAppPool
2. IUSR

with Access Rights:

1. Read & Execute
2. List folder contents
3. Read

That's it!

Read on for a more detailed explanation...

1. Open IIS and select your application.
2. On the right side click on Authentication.
3. Select "Anonymous authentication" here.
4. The following dialog pops up.

Grant access to the web application folder's ACL depending what is selected in the pic above:

• Specific user: grant access for both IUSR (in my case) + IIS AppPool\DefaultAppPool
• Application pool identity: grant access for IIS AppPool\DefaultAppPool only

IIS AppPool\DefaultAppPool account is the default AppPool account for new IIS web applications, if you have set a custom account, use the custom one.

Give the following permissions to the account(s):

1. Read & Execute
2. List folder contents
3. Read

After hours of debugging I could only get this to work using the following packages:

requests[security]==2.7.0  # not 2.18.1
cryptography==1.9  # not 2.0

using OpenSSL 1.0.2g 1 Mar 2016

Without these packages verify=False was not working.

I hope this helps someone.

Let's consider those tables :

A

id | SomeData

B

id | id_A | SomeOtherData

id_A being a foreign key to table A

Writting this query :

SELECT *
FROM A
LEFT JOIN B
ON A.id = B.id_A;

Will provide this result :

/ : part of the result
                                       B
                      +---------------------------------+
            A         |                                 |
+---------------------+-------+                         |
|/////////////////////|///////|                         |
|/////////////////////|///////|                         |
|/////////////////////|///////|                         |
|/////////////////////|///////|                         |
|/////////////////////+-------+-------------------------+
|/////////////////////////////|
+-----------------------------+

What is in A but not in B means that there is null values for B.

Now, let's consider a specific part in B.id_A, and highlight it from the previous result :

/ : part of the result
* : part of the result with the specific B.id_A
                                       B
                      +---------------------------------+
            A         |                                 |
+---------------------+-------+                         |
|/////////////////////|///////|                         |
|/////////////////////|///////|                         |
|/////////////////////+---+///|                         |
|/////////////////////|***|///|                         |
|/////////////////////+---+---+-------------------------+
|/////////////////////////////|
+-----------------------------+

Writting this query :

SELECT *
FROM A
LEFT JOIN B
ON A.id = B.id_A
AND B.id_A = SpecificPart;

Will provide this result :

/ : part of the result
* : part of the result with the specific B.id_A
                                       B
                      +---------------------------------+
            A         |                                 |
+---------------------+-------+                         |
|/////////////////////|       |                         |
|/////////////////////|       |                         |
|/////////////////////+---+   |                         |
|/////////////////////|***|   |                         |
|/////////////////////+---+---+-------------------------+
|/////////////////////////////|
+-----------------------------+

Because this removes in the inner join the values that aren't in B.id_A = SpecificPart

Now, let's change the query to this :

SELECT *
FROM A
LEFT JOIN B
ON A.id = B.id_A
WHERE B.id_A = SpecificPart;

The result is now :

/ : part of the result
* : part of the result with the specific B.id_A
                                       B
                      +---------------------------------+
            A         |                                 |

None of the configuration above worked for me on my CentOS 7 server. After hours of searching, that what worked for me:

Edit file phpMyAdmin.conf

sudo nano /etc/httpd/conf.d/phpMyAdmin.conf

And replace the existing <Directory> ... </Directory> node with the following:

<Directory /usr/share/phpMyAdmin/>
   AddDefaultCharset UTF-8

   <IfModule mod_authz_core.c>
     # Apache 2.4
     <RequireAny>
       #Require ip 127.0.0.1
       #Require ip ::1
       Require all granted
     </RequireAny>
   </IfModule>
   <IfModule !mod_authz_core.c>
     # Apache 2.2
     Order Deny,Allow
     Deny from All
     Allow from 127.0.0.1
     Allow from ::1
   </IfModule>
</Directory>

There are multiple options. See Split single comma delimited string into rows in Oracle

You just need to add LEVEL in the select list as a column, to get the sequence number to each row returned. Or, ROWNUM would also suffice.

Using any of the below SQLs, you could include them into a FUNCTION.

INSTR in CONNECT BY clause:

SQL> WITH DATA AS
  2    ( SELECT 'word1, word2, word3, word4, word5, word6' str FROM dual
  3    )
  4  SELECT trim(regexp_substr(str, '[^,]+', 1, LEVEL)) str
  5  FROM DATA
  6  CONNECT BY instr(str, ',', 1, LEVEL - 1) > 0
  7  /

STR
----------------------------------------
word1
word2
word3
word4
word5
word6

6 rows selected.

REGEXP_SUBSTR in CONNECT BY clause:

SQL> WITH DATA AS
  2    ( SELECT 'word1, word2, word3, word4, word5, word6' str FROM dual
  3    )
  4  SELECT trim(regexp_substr(str, '[^,]+', 1, LEVEL)) str
  5  FROM DATA
  6  CONNECT BY regexp_substr(str , '[^,]+', 1, LEVEL) IS NOT NULL
  7  /

STR

  4      SELECT trim(regexp_substr(str, '[^,]+', 1, LEVEL)) str
  5      FROM DATA
  6      CONNECT BY LEVEL 

Using XMLTABLE

You could also use DBMS_UTILITY package provided by Oracle. It provides various utility subprograms. One such useful utility is COMMA_TO_TABLE procedure, which converts a comma-delimited list of names into a PL/SQL table of names.

Read DBMS_UTILITY.COMMA_TO_TABLE

The /sys filesystem should contain plenty information for your quest. My system (2.6.32-40-generic #87-Ubuntu) suggests:

/sys/class/tty

Which gives you descriptions of all TTY devices known to the system. A trimmed down example:

# ll /sys/class/tty/ttyUSB*
lrwxrwxrwx 1 root root 0 2012-03-28 20:43 /sys/class/tty/ttyUSB0 -> ../../devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.4/2-1.4:1.0/ttyUSB0/tty/ttyUSB0/
lrwxrwxrwx 1 root root 0 2012-03-28 20:44 /sys/class/tty/ttyUSB1 -> ../../devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.3/2-1.3:1.0/ttyUSB1/tty/ttyUSB1/

Following one of these links:

# ll /sys/class/tty/ttyUSB0/
insgesamt 0
drwxr-xr-x 3 root root    0 2012-03-28 20:43 ./
drwxr-xr-x 3 root root    0 2012-03-28 20:43 ../
-r--r--r-- 1 root root 4096 2012-03-28 20:49 dev
lrwxrwxrwx 1 root root    0 2012-03-28 20:43 device -> ../../../ttyUSB0/
drwxr-xr-x 2 root root    0 2012-03-28 20:49 power/
lrwxrwxrwx 1 root root    0 2012-03-28 20:43 subsystem -> ../../../../../../../../../../class/tty/
-rw-r--r-- 1 root root 4096 2012-03-28 20:43 uevent

Here the dev file contains this information:

# cat /sys/class/tty/ttyUSB0/dev
188:0

This is the major/minor node. These can be searched in the /dev directory to get user-friendly names:

# ll -R /dev |grep "188, *0"
crw-rw----   1 root dialout 188,   0 2012-03-28 20:44 ttyUSB0

The /sys/class/tty dir contains all TTY devices but you might want to exclude those pesky virtual terminals and pseudo terminals. I suggest you examine only those which have a device/driver entry:

# ll /sys/class/tty/*/device/driver
lrwxrwxrwx 1 root root 0 2012-03-28 19:07 /sys/class/tty/ttyS0/device/driver -> ../../../bus/pnp/drivers/serial/
lrwxrwxrwx 1 root root 0 2012-03-28 19:07 /sys/class/tty/ttyS1/device/driver -> ../../../bus/pnp/drivers/serial/
lrwxrwxrwx 1 root root 0 2012-03-28 19:07 /sys/class/tty/ttyS2/device/driver -> ../../../bus/platform/drivers/serial8250/
lrwxrwxrwx 1 root root 0 2012-03-28 19:07 /sys/class/tty/ttyS3/device/driver -> ../../../bus/platform/drivers/serial8250/
lrwxrwxrwx 1 root root 0 2012-03-28 20:43 /sys/class/tty/ttyUSB0/device/driver -> ../../../../../../../../bus/usb-serial/drivers/ftdi_sio/
lrwxrwxrwx 1 root root 0 2012-03-28 21:15 /sys/class/tty/ttyUSB1/device/driver -> ../../../../../../../../bus/usb-serial/drivers/ftdi_sio/

If you don't want to use any external libraries or 3rd party tools, Please try below code.

• This will parse xml into python dictionary
• This will parse xml attrbutes as well
• This will also parse empty tags like <tag/> and tags with only attributes like <tag var=val/>

Code

ToggleButton inherits from TextView so you can set drawables to be displayed at the 4 borders of the text. You can use that to display the icon you want on top of the text and hide the actual text

<ToggleButton
    android:id="@+id/toggleButton1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:drawableTop="@android:drawable/ic_menu_info_details"
    android:gravity="center"
    android:textOff=""
    android:textOn=""
    android:textSize="0dp" />

The result compared to regular ToggleButton looks like

The seconds option is to use an ImageSpan to actually replace the text with an image. Looks slightly better since the icon is at the correct position but can't be done with layout xml directly.

You create a plain ToggleButton

<ToggleButton
    android:id="@+id/toggleButton3"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:checked="false" />

Then set the "text" programmatially

ToggleButton button = (ToggleButton) findViewById(R.id.toggleButton3);
ImageSpan imageSpan = new ImageSpan(this, android.R.drawable.ic_menu_info_details);
SpannableString content = new SpannableString("X");

The result here in the middle - icon is placed slightly lower since it takes the place of the text.

When the length of v will be zero, it'll give you the value error.

You should check the length or you should check the list first whether it is none or not.

If you mean the type of procedure you find in SQL Server, prior to 2010, you can't. If you want a query that accepts a parameter, you can use the query design window:

 PARAMETERS SomeParam Text(10);
 SELECT Field FROM Table
 WHERE OtherField=SomeParam

You can also say:

CREATE PROCEDURE ProcedureName
   (Parameter1 datatype, Parameter2 datatype) AS
   SQLStatement

From: http://msdn.microsoft.com/en-us/library/aa139977(office.10).aspx#acadvsql_procs

Note that the procedure contains only one statement.

Sometimes it may be required to execute the update atomically that is using one update request to the database without reading it first.

Also get-set attribute-save may cause problems if such updates may be done concurrently or if you need to set the new value based on the old field value.

In such cases query expressions together with update may by useful:

TemperatureData.objects.filter(id=1).update(value=F('value') + 1)

In a nutshell, it is your lockscreen.

PIN, pattern, face, password locks or the default lock (slide to unlock), but it is your lock screen.

USE MyDatabase
SELECT Count(*)
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_TYPE = 'BASE TABLE';

to get table counts

SELECT COUNT(*)
FROM information_schema.tables
WHERE table_schema = 'dbName';

this also works

USE databasename;
SHOW TABLES;
SELECT FOUND_ROWS();

Had same issue, however I'm using Macbook Pro (2016) which has USB-c only and I forgot my adapter at home.

Since unable to run adb at all on my development machine, I found a different approach.

Connecting phone with USB cable to another computer (in same WiFi) and enable run adb tcpip from there.

Master-machine : computer where development goes on, with only USB-C connectors

Slave-machine: another computer with USB and in same WiFi

Steps:

1. Connect the phone to a different computer (slave-machine)
2. Run adb usb && adb tcpip 5555 from there

3. On master machine

   deko$: adb devices
   List of devices attached
   
   deko$: adb connect 10.0.20.153:5555
   connected to 10.0.20.153:5555
   

4. Now Android Studio or Xamarin can install and run app on the phone

Sidenote:

I also tested Bluetooth tethering from the Phone to Master-machine and successfully connected to phone. Both Android Studio and Xamarin worked well, however the upload process, from Xamarin was taking long time. But it works.

Open up a command prompt and type java -jar jbpm-installer-3.2.7.jar

It looks like there's an extra space character in your string. You can use trim() to remove leading and trailing whitespaces:

temp1 = Integer.parseInt(display.getText().trim(), 16 );

Or if you think the presence of a space means there's something else wrong, you'll have to look into it yourself, since we don't have the rest of your code.

Try it:

$table->integer('user_id')->unsigned()->nullable();

I recently ran into this as well and this was a helpful post. I took the above Topera a step further and this works for me in both chrome and firefox:

var temp = new Date(  Date("2010-08-17 12:09:36")   );
alert(temp);

the internal call to Date() returns a string that new Date() can parse.

Well, once you have your font, you can invoke deriveFont. For example,

helvetica = helvetica.deriveFont(Font.BOLD, 12f);

Changes the font's style to bold and its size to 12 points.

If there are are no duplicate elements or you don't care about them, then you can use the Set class:

a1 = Set.new [5, 1, 6, 14, 2, 8]
a2 = Set.new [2, 6, 15]
a1.subset?(a2)
=> false

Behind the scenes this uses

all? { |o| set.include?(o) }

Or if "NOT EXISTS" are not implemented

SELECT *
FROM   B
WHERE (SELECT count(*)  FROM   A WHERE  A.ID = B.ID) < 1

Simple answer

If you want to match single character, put it inside those brackets [ ]

Examples

• match + ...... [+] or +
• match a ...... a
• match & ...... &

...and so on. You can check your regular expresion online on this site: https://regex101.com/

1. Create a UNIQUE constraint on your subs_email column, if one does not already exist:

   ALTER TABLE subs ADD UNIQUE (subs_email)
   

2. Use INSERT ... ON DUPLICATE KEY UPDATE:

   INSERT INTO subs
     (subs_name, subs_email, subs_birthday)
   VALUES
     (?, ?, ?)
   ON DUPLICATE KEY UPDATE
     subs_name     = VALUES(subs_name),
     subs_birthday = VALUES(subs_birthday)
   

You can use the VALUES(col_name) function in the UPDATE clause to refer to column values from the INSERT portion of the INSERT ... ON DUPLICATE KEY UPDATE - dev.mysql.com

3. Note that I have used parameter placeholders in the place of string literals, as one really should be using parameterised statements to defend against SQL injection attacks.

Check these things.

1.A device is connected to your system or not.

2.Deployment target in xcode. (General->Deployment info->Deployment target) It should match with the ios version of your device.

3.Change your bundle identifier. Follow general rules of setting a unique bundle identifier for yourproject while running in device. See this what is correct format of bundle identifier in iOS?

Also be careful with the number of bundle identifiers you set in the project. Please remember all bundle identifiers or note it down somewhere. Since you are using a free account you have limited access to the number of bundle id's.

You should also disable push notifications in the "Capabilities" section of the project. Try changing "App groups" as well in the format of group.com.someString.

These things helped me run my app in real device without any errors.

It is possible to increase heap size allocated by the JVM by using command line options Here we have 3 options

-Xms<size>        set initial Java heap size
-Xmx<size>        set maximum Java heap size
-Xss<size>        set java thread stack size

java -Xms16m -Xmx64m ClassName

In the above line we can set minimum heap to 16mb and maximum heap 64mb

We can pass multiple parameters with var_dump like:

var_dump("array1",$array1,"array2",$array2);

The question has been answered, my contribution consists in clarifying one thing that may confuse beginners:

Some of the suggested and correct answers used firstChild.data and others used firstChild.nodeValue instead. In case you are wondering what is the different between them, you should remember they do the same thing because nodeValue is just an alias for data.

The reference to my statement can be found as a comment on the source code of minidom:

#nodeValue is an alias for data

If you want to do it safely, you may want to use http://docs.python.org/library/ast.html#ast.literal_eval

from this answer: Python "safe" eval (string to bool/int/float/None/string)

It might not do math, but you could parse the math operators and then operate on safely evaluated terms.

None of the current answers show the InputStream being closed (this will leak a file descriptor), and/or don't deal with .getResourceAsStream() returning null when the resource is not found (this will lead to a NullPointerException with the confusing message, "inStream parameter is null"). You need something like the following:

String propertiesFilename = "server.properties";
Properties prop = new Properties();
try (var inputStream = getClass().getClassLoader().getResourceAsStream(propertiesFilename)) {
    if (inputStream == null) {
        throw new FileNotFoundException(propertiesFilename);
    }
    prop.load(inputStream);
} catch (IOException e) {
    throw new RuntimeException(
                "Could not read " + propertiesFilename + " resource file: " + e);
}

If your code doesn't cross filesystem boundaries, i.e. you're just working with one filesystem, then use java.io.File.separator.

This will, as explained, get you the default separator for your FS. As Bringer128 explained, System.getProperty("file.separator") can be overriden via command line options and isn't as type safe as java.io.File.separator.

The last one, java.nio.file.FileSystems.getDefault().getSeparator(); was introduced in Java 7, so you might as well ignore it for now if you want your code to be portable across older Java versions.

So, every one of these options is almost the same as others, but not quite. Choose one that suits your needs.

Thanks for the idea of breaking down a formula Werner!

Using Alt+Enter allows one to put each bit of a complex substitute formula on separate lines: they become easier to follow and automatically line themselves up when Enter is pressed.

Just make sure you have enough end statements to match the number of substitute( lines either side of the cell reference.

As in this example:

=
substitute(
substitute(
substitute(
substitute(
B11
,"(","")
,")","")
,"[","")
,"]","")

becomes:

=
SUBSTITUTE(
SUBSTITUTE(
SUBSTITUTE(
SUBSTITUTE(B12,"(",""),")",""),"[",""),"]","")

which works fine as is, but one can always delete the extra paragraphs manually:

=SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(B12,"(",""),")",""),"[",""),"]","")

Name > substitute()

[American Samoa] > American Samoa

Try the following:

create these folders under storage/framework:

You could just nest the Text components with the required style. The style will be applied along with already defined style in the first Text component.

Example:

 <Text style={styles.paragraph}>
   Trouble singing in. <Text style={{fontWeight: "bold"}}> Resolve</Text>
 </Text>

You could download Better Touch Tools. It's an app that allows you to make custom key-bindings and shortcuts over your entire system or individual apps. Using it, you could make a shortcut in the terminal that emulates ctrl-a/ctrl-e whenever you press cmd-left/cmd-right, respectively. I definitely recommend it! I've been using it for years and I have over 50 shortcuts spread across several different apps.

There's only one registered mediatype for SVG, and that's the one you listed, image/svg+xml. You can of course serve SVG as XML too, though browsers tend to behave differently in some scenarios if you do, for example I've seen cases where SVG used in CSS backgrounds fail to display unless served with the image/svg+xml mediatype.

If you want to fully copy properties of an object in a different instance, you may want to use this technique:

Serialize it to JSON and then de-serialize it back to Object.

In bootstrap 4 use:

This will push the navbar to the right. Use mr-auto to push it to the left, this is the default behaviour.

I had a similar issue where videos inside a <video> tag only played on Chrome and Firefox but not Safari. Here is what I did to fix it...

A weird trick I found was to have two different references to your video, one in a <video> tag for Chrome and Firefox, and the other in an <img> tag for Safari. Fun fact, videos do actually play in an <img> tag on Safari. After this, write a simple script to hide one or the other when a certain browser is in use. So for example:

<video id="video-tag" autoplay muted loop playsinline> 
    <source src="video.mp4" type="video/mp4" />  
</video>
<img id="img-tag" src="video.mp4">

<script type="text/javascript">
    function BrowserDetection() {

    //Check if browser is Safari, if it is, hide the <video> tag, otherwise hide the <img> tag
    if (navigator.userAgent.search("Safari") >= 0 && navigator.userAgent.search("Chrome") < 0) {
        document.getElementById('video-tag').style.display= "none";
    } else {
        document.getElementById('img-tag').style.display= "none";
    }               

    //And run the script. Note that the script tag needs to be run after HTML so where you place it is important. 
    BrowserDetection();
</script>

This also helps solve the problem of a thin black frame/border on some videos on certain browsers where they are rendered incorrectly.

You can use @echo ( @echo + [space] + [insecable space] )

Note: The insecable space can be obtained with Alt+0160

Hope it helps :)

[edit] Hmm you're right, I needed it in a Makefile, it works perfectly in there. I guess my answer is not adapted for batch files... My bad.

Compare the cell with "" (empty line):

=IF(A1="",1,0)

I have experienced that a drop-down menu, referring to a control range (for example after copying sheets from one workbook to another), will keep that cell reference after copying the worksheet, and keeps a data connection which is invisible in "Connections". I found this in the "Search" menu in the ribbon, where an arrow can be selected to mark objects. Underneath the arrow is a menu selection to see all the objects listed in a panel. Then you can delete those unwanted objects and the data source/connection is gone...

Try netstat like this: netstat -ntp, without the -l. It will show tcp connection in TIME_WAIT state.

Is there a way to detect if a key is currently down in JavaScript?

Nope. The only possibility is monitoring each keyup and keydown and remembering.

after some period of time the key begins to repeat, firing off keydown and keyup events like a fiend.

It shouldn't. You'll definitely get keypress repeating, and in many browsers you'll also get repeated keydown, but if keyup repeats, it's a bug.

Unfortunately it is not a completely unheard-of bug: on Linux, Chromium, and Firefox (when it is being run under GTK+, which it is in popular distros such as Ubuntu) both generate repeating keyup-keypress-keydown sequences for held keys, which are impossible to distinguish from someone hammering the key really fast.

The rep.row function seems to sometimes make lists for columns, which leads to bad memory hijinks. I have written the following which seems to work well:

library(plyr)
rep.row <- function(r, n){
  colwise(function(x) rep(x, n))(r)
}

The second button from the left. The one on the right of the house in the image you posted is your logout button.

For your error message try this link in the documentation: http://wiki.phpmyadmin.net/pma/Configuration_storage

Make certain you have a phpadmin control user account created. This is covered in the second paragraph in on the documentation page in the link.

d = {0: 'zero', '0': 'ZERO', 1: 'one', '1': 'ONE'}

print("List of enumerated d= ", list(enumerate(d.items())))

output:

List of enumerated d=  [(0, (0, 'zero')), (1, ('0', 'ZERO')), (2, (1, 'one')), (3, ('1', 'ONE'))]

This function will print variable name with its value:

import inspect

def print_this(var):
    callers_local_vars = inspect.currentframe().f_back.f_locals.items()
    print(str([k for k, v in callers_local_vars if v is var][0])+': '+str(var))

***Input & Function call:***
my_var = 10

print_this(my_var)

***Output**:*
my_var: 10

Map<String, Integer> map = new HashMap<>();
map.put("test1", 1);
map.put("test2", 2);

Map<String, Integer> map2 = new HashMap<>();
map.forEach(map2::put);

System.out.println("map: " + map);
System.out.println("map2: " + map2);
// Output:
// map:  {test2=2, test1=1}
// map2: {test2=2, test1=1}

You can use the forEach method to do what you want.

What you're doing there is:

map.forEach(new BiConsumer<String, Integer>() {
    @Override
    public void accept(String s, Integer integer) {
        map2.put(s, integer);     
    }
});

Which we can simplify into a lambda:

map.forEach((s, integer) ->  map2.put(s, integer));

And because we're just calling an existing method we can use a method reference, which gives us:

map.forEach(map2::put);

You may use Reflection to set the UseDefaultCredentials-Property from Code to "true"

System.Reflection.PropertyInfo pInfo = System.Net.WebRequest.DefaultWebProxy.GetType().GetProperty("WebProxy", 
System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance);

((System.Net.WebProxy)pInfo.GetValue(System.Net.WebRequest.DefaultWebProxy, null)).UseDefaultCredentials = true;

One other scenario which I encountered.

String imageName ="Hello" and then when it is passed into getIdentifier function as first argument, it will pass the name with string null termination and will always return zero. Pass this imageName.substring(0, imageName.length()-1)

Timer.Elapsed expects method of specific signature (with arguments object and EventArgs). If you want to use your PlayMusicEvent method with additional argument evaluated during event registration, you can use lambda expression as an adapter:

myTimer.Elapsed += new ElapsedEventHandler((sender, e) => PlayMusicEvent(sender, e, musicNote));

Edit: you can also use shorter version:

myTimer.Elapsed += (sender, e) => PlayMusicEvent(sender, e, musicNote);

Try this, may this will help you

SELECT DATEDIFF(DAY, DATEADD(DAY,-1,'2013-03-13 00:00:00.000') , GETDATE())

The nextInt() method leaves the \n (end line) symbol and is picked up immediately by nextLine(), skipping over the next input. What you want to do is use nextLine() for everything, and parse it later:

String nextIntString = keyboard.nextLine(); //get the number as a single line
int nextInt = Integer.parseInt(nextIntString); //convert the string to an int

This is by far the easiest way to avoid problems--don't mix your "next" methods. Use only nextLine() and then parse ints or separate words afterwards.

Also, make sure you use only one Scanner if your are only using one terminal for input. That could be another reason for the exception.

Last note: compare a String with the .equals() function, not the == operator.

if (playAgain == "yes"); // Causes problems
if (playAgain.equals("yes")); // Works every time

char[] chars = new char[10];
Arrays.fill(chars, '*');
String text = new String(chars);

It really depends on how you write your bash scripts. If your /bin/sh is symlinked to bash, when bash is invoked as sh, some features are unavailable.

If you want bash-specific, non-POSIX features, use #!/bin/bash

At least for Ubuntu (maybe also others) works this (inspired by a previous post in this thread):

printf "Installed with pip:";
pip list 2>/dev/null | gawk '{print $1;}' | while read; do pip show "${REPLY}" 2>/dev/null | grep 'Location: /usr/local/lib/python2.7/dist-packages' >/dev/null; if (( $? == 0 )); then printf " ${REPLY}"; fi; done; echo

It means that no rows will be returned if @region is NULL, when used in your first example, even if there are rows in the table where Region is NULL.

When ANSI_NULLS is on (which you should always set on anyway, since the option to not have it on is going to be removed in the future), any comparison operation where (at least) one of the operands is NULL produces the third logic value - UNKNOWN (as opposed to TRUE and FALSE).

UNKNOWN values propagate through any combining boolean operators if they're not already decided (e.g. AND with a FALSE operand or OR with a TRUE operand) or negations (NOT).

The WHERE clause is used to filter the result set produced by the FROM clause, such that the overall value of the WHERE clause must be TRUE for the row to not be filtered out. So, if an UNKNOWN is produced by any comparison, it will cause the row to be filtered out.

@user1227804's answer includes this quote:

If both sides of the comparison are columns or compound expressions, the setting does not affect the comparison.

from SET ANSI_NULLS^*

However, I'm not sure what point it's trying to make, since if two NULL columns are compared (e.g. in a JOIN), the comparison still fails:

create table #T1 (
    ID int not null,
    Val1 varchar(10) null
)
insert into #T1(ID,Val1) select 1,null

create table #T2 (
    ID int not null,
    Val1 varchar(10) null
)
insert into #T2(ID,Val1) select 1,null

select * from #T1 t1 inner join #T2 t2 on t1.ID = t2.ID and t1.Val1 = t2.Val1

The above query returns 0 rows, whereas:

select * from #T1 t1 inner join #T2 t2 on t1.ID = t2.ID and (t1.Val1 = t2.Val1 or t1.Val1 is null and t2.Val1 is null)

Returns one row. So even when both operands are columns, NULL does not equal NULL. And the documentation for = doesn't have anything to say about the operands:

When you compare two NULL expressions, the result depends on the ANSI_NULLS setting:

If ANSI_NULLS is set to ON, the result is NULL¹, following the ANSI convention that a NULL (or unknown) value is not equal to another NULL or unknown value.

If ANSI_NULLS is set to OFF, the result of NULL compared to NULL is TRUE.

Comparing NULL to a non-NULL value always results in FALSE².

However, both ¹ and ² are incorrect - the result of both comparisons is UNKNOWN.

^*The cryptic meaning of this text was finally discovered years later. What it actually means is that, for those comparisons, the setting has no effect and it always acts as if the setting were ON. Would have been clearer if it had stated that SET ANSI_NULLS OFF was the setting that had no affect.

If you want to ignore the insertion of existing value, there must be a Key field in your Table. Just create a table With Primary Key Field Like:

CREATE TABLE IF NOT EXISTS TblUsers (UserId INTEGER PRIMARY KEY, UserName varchar(100), ContactName varchar(100),Password varchar(100));

And Then Insert Or Replace / Insert Or Ignore Query on the Table Like:

INSERT OR REPLACE INTO TblUsers (UserId, UserName, ContactName ,Password) VALUES('1','UserName','ContactName','Password');

It Will Not Let it Re-Enter The Existing Primary key Value... This Is how you can Check Whether a Value exists in the table or not.

You'll have to use a setTimeout (like you are) but also store the reference so you can keep resetting the limit. Something like:

//_x000D_
// $('#element').donetyping(callback[, timeout=1000])_x000D_
// Fires callback when a user has finished typing. This is determined by the time elapsed_x000D_
// since the last keystroke and timeout parameter or the blur event--whichever comes first._x000D_
//   @callback: function to be called when even triggers_x000D_
//   @timeout:  (default=1000) timeout, in ms, to to wait before triggering event if not_x000D_
//              caused by blur._x000D_
// Requires jQuery 1.7+_x000D_
//_x000D_
;(function($){_x000D_
    $.fn.extend({_x000D_
        donetyping: function(callback,timeout){_x000D_
            timeout = timeout || 1e3; // 1 second default timeout_x000D_
            var timeoutReference,_x000D_
                doneTyping = function(el){_x000D_
                    if (!timeoutReference) return;_x000D_
                    timeoutReference = null;_x000D_

You can have - characters in your images. Assume you have a local image (not a local registry) named centos-base-image with tag 7.3.1611.

docker version 
      Client:

In the example above FROM is fetching your local image, you can provide additional instructions to fetch an image from your custom registry (e.g. FROM localhost:5000/my-image:with.tag). See https://docs.docker.com/engine/reference/commandline/pull/#pull-from-a-different-registry and https://docs.docker.com/registry/#tldr

Finally, if your image is not being resolved when providing a name, try adding a tag to the image when you create it

This GitHub thread describes a similar issue of not finding local images by name.

By omitting a specific tag, docker will look for an image tagged "latest", so either create an image with the :latest tag, or change your FROM

In Windows 7 and later, this will do the trick for you

• Select the file/files.
• Hold the shift key and then right-click on the selected file/files.
• You will see Copy as Path. Click that.
• Open a Notepad file and paste and you will be good to go.

The menu item Copy as Path is not available in Windows XP.

S3N is not a default file format. You need to build your version of Spark with a version of Hadoop that has the additional libraries used for AWS compatibility. Additional info I found here, https://www.hakkalabs.co/articles/making-your-local-hadoop-more-like-aws-elastic-mapreduce

SELECT * FROM Table where codtable not in (Select codtable from Table where fecha is null)

Hint: If you can´t see the app-debug.apk in your debug folder, you have to click on BUILD --> Rebuild Project in Android Studio.

As discussed somewhat in the question comments, this is one way you could do it:

• When you first retrieve the data, loop through all locations and set storeDefault to the store that is currently the default.
• In the markup: <input ... ng-model="$parent.storeDefault" value="{{location.id}}">
• Before you save the data, loop through all the merchant.storeLocations and set isDefault to false except for the store where location.id compares equal to storeDefault.

The above assumes that each location has a field (e.g., id) that holds a unique value.

Note that $parent.storeDefault is used because ng-repeat creates a child scope, and we want to manipulate the storeDefault parameter on the parent scope.

Fiddle.

first convert your array too JSON

while($query->fetch()){
   $col[] = json_encode($row,JSON_UNESCAPED_UNICODE);
}

then vonvert back it to array

foreach($col as &$array){
   $array = json_decode($array,true);
}

good luck

Not possible.

You can only store, simple values in SharedPrefences SharePreferences.Editor

What particularly about the class do you need to save?

there are four types of strings available in php. They are single quotes ('), double quotes (") and Nowdoc (<<<'EOD') and heredoc(<<<EOD) strings

you can use both single quotes and double quotes inside heredoc string. Variables will be expanded just as double quotes.

nowdoc strings will not expand variables just like single quotes.

ref: http://www.php.net/manual/en/language.types.string.php#language.types.string.syntax.heredoc

You could do it like this:

• mark the <a> with a class, say "cancel"

• set up the dialog by acting on all elements with class="cancel":

  $('a.cancel').click(function() { 
    var a = this; 
    $('#myDialog').dialog({
      buttons: {
        "Yes": function() {
           window.location = a.href; 
        }
      }
    }); 
    return false;
  });
  

(plus your other options)

The key points here are:

• make it as unobtrusive as possible
• if all you need is the URL, you already have it in the href.

However, I recommend that you make this a POST instead of a GET, since a cancel action has side effects and thus doesn't comply with GET semantics...

Illegal State Exception is an Unchecked exception.

It indicate that method has been invoked at wrong time.

example:

Thread t = new Thread();
t.start();
//
//
t.start();

output:

Runtime Excpetion: IllegalThreadStateException

We cant start the Thread again, it will throw IllegalStateException.

Using jQuery 1.9.1 I just found out that, although technically identical)*, this did not work in IE10 (but in Firefox):

// did not work in IE10
$(function() {
    $(window).resize(CmsContent.adjustSize);
});

while this worked in both browsers:

// did work in IE10
$(function() {
    $(window).bind('resize', function() {
        CmsContent.adjustSize();
    };
});

Edit:
)* Actually not technically identical, as noted and explained in the comments by WraithKenny and Henry Blyth.

Your app is crashing at:

welcomePlayer.setText("Welcome Back, " + String.valueOf(mPlayer.getName(this)) + " !");

because mPlayer=null.

You forgot to initialize Player mPlayer in your PlayGame Activity.

mPlayer = new Player(context,"");

The short answer is: properties wins hands down. Always.

There is sometimes a need for getters and setters, but even then, I would "hide" them to the outside world. There are plenty of ways to do this in Python (getattr, setattr, __getattribute__, etc..., but a very concise and clean one is:

def set_email(self, value):
    if '@' not in value:
        raise Exception("This doesn't look like an email address.")
    self._email = value

def get_email(self):
    return self._email

email = property(get_email, set_email)

Here's a brief article that introduces the topic of getters and setters in Python.

ALTER TABLE [table_name] ALTER COLUMN [column_name] varchar(150)

better to use touchstart event with .on() jQuery method:

$(window).load(function() { // better to use $(document).ready(function(){
    $('.List li').on('click touchstart', function() {
        $('.Div').slideDown('500');
    });
});

And i don't understand why you are using $(window).load() method because it waits for everything on a page to be loaded, this tend to be slow, while you can use $(document).ready() method which does not wait for each element on the page to be loaded first.

Example: Read json from file

/* test.json */
{
   "appDesc": {
      "description": "SomeDescription",
      "message": "SomeMessage"
   },
   "appName": {
      "description": "Home",
      "message": "Welcome",
      "imp":["awesome","best","good"]
   }
}


void readJson()
   {
      QString val;
      QFile file;
      file.setFileName("test.json");
      file.open(QIODevice::ReadOnly | QIODevice::Text);
      val = file.readAll();
      file.close();
      qWarning() << val;
      QJsonDocument d = QJsonDocument::fromJson(val.toUtf8());
      QJsonObject sett2 = d.object();
      QJsonValue value = sett2.value(QString("appName"));
      qWarning() << value;
      QJsonObject item = value.toObject();
      qWarning() << tr("QJsonObject of description: ") << item;

      /* in case of string value get value and convert into string*/
      qWarning() << tr("QJsonObject[appName] of description: ") << item["description"];
      QJsonValue subobj = item["description"];
      qWarning() << subobj.toString();

      /* in case of array get array and convert into string*/
      qWarning() << tr("QJsonObject[appName] of value: ") << item["imp"];
      QJsonArray test = item["imp"].toArray();
      qWarning() << test[1].toString();
   }

OUTPUT

QJsonValue(object, QJsonObject({"description": "Home","imp": ["awesome","best","good"],"message": "YouTube"}) ) 
"QJsonObject of description: " QJsonObject({"description": "Home","imp": ["awesome","best","good"],"message": "YouTube"}) 
"QJsonObject[appName] of description: " QJsonValue(string, "Home") 
"Home" 
"QJsonObject[appName] of value: " QJsonValue(array, QJsonArray(["awesome","best","good"]) ) 
"best" 

Example: Read json from string

Assign json to string as below and use the readJson() function shown before:

val =   
'  {
       "appDesc": {
          "description": "SomeDescription",
          "message": "SomeMessage"
       },
       "appName": {
          "description": "Home",
          "message": "Welcome",
          "imp":["awesome","best","good"]
       }
    }';

OUTPUT

QJsonValue(object, QJsonObject({"description": "Home","imp": ["awesome","best","good"],"message": "YouTube"}) ) 
"QJsonObject of description: " QJsonObject({"description": "Home","imp": ["awesome","best","good"],"message": "YouTube"}) 
"QJsonObject[appName] of description: " QJsonValue(string, "Home") 
"Home" 
"QJsonObject[appName] of value: " QJsonValue(array, QJsonArray(["awesome","best","good"]) ) 
"best" 

you also call fragment method using interface like

first you create interface

public interface InterfaceName {
    void methodName();
}

after creating interface you implement interface in your fragment

MyFragment extends Fragment implements InterfaceName {
    @overide
    void methodName() {

    }
}

and you create the reference of interface in your activity

class Activityname extends AppCompatActivity {
    Button click;
    MyFragment fragment;

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity);

        click = findViewById(R.id.button);

        fragment = new MyFragment();

        click.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
               fragment.methodName();
            }
        });
    }
}

I had to decide between the parseFloat() and Number() conversions before I could make toFixed() call. Here's an example of a number formatting post-capturing user input.

HTML:

<input type="number" class="dec-number" min="0" step="0.01" />

Event handler:

$('.dec-number').on('change', function () {
     const value = $(this).val();
     $(this).val(value.toFixed(2));
});

The above code will result in TypeError exception. Note that although the html input type is "number", the user input is actually a "string" data type. However, toFixed() function may only be invoked on an object that is a Number.

My final code would look as follows:

$('.dec-number').on('change', function () {
     const value = Number($(this).val());
     $(this).val(value.toFixed(2));
});

The reason I favor to cast with Number() vs. parseFloat() is because I don't have to perform an extra validation neither for an empty input string, nor NaN value. The Number() function would automatically handle an empty string and covert it to zero.

The simplest way is -

public class SecondLargest {
    public static void main(String[] args) {
        int[] arr = { 1, 2, 5, 6, 3 };

        int first = Integer.MIN_VALUE;
        int second = Integer.MIN_VALUE;
        for (int i = 0; i < arr.length; i++) {
            // If current element is smaller than first then update both first
            // and second
            if (arr[i] > first) {
                second = first;
                first = arr[i];
            }
            // If arr[i] is in between first and second then update second
            else if (arr[i] > second && arr[i] != first) {
                second = arr[i];
            }
        }
    }
}

You can also put the JavaScript code in script tags, rather than a separate function. <script>//JS Code</script> This way the code will get executes on Page Load.

I had much issues with this one too. I finally found out what's the final deal.

Referring to @Gokhan Oner answer, once you've got your Service class and the POJO representing your object, your YAML config file nice and lean, if you use the annotation @ConfigurationProperties, you have to explicitly get the object for being able to use it. Like :

@ConfigurationProperties(prefix = "available-payment-channels-list")
//@Configuration  <-  you don't specificly need this, instead you're doing something else
public class AvailableChannelsConfiguration {

    private String xyz;
    //initialize arraylist
    private List<ChannelConfiguration> channelConfigurations = new ArrayList<>();

    public AvailableChannelsConfiguration() {
        for(ChannelConfiguration current : this.getChannelConfigurations()) {
            System.out.println(current.getName()); //TADAAA
        }
    }

    public List<ChannelConfiguration> getChannelConfigurations() {
        return this.channelConfigurations;
    }

    public static class ChannelConfiguration {
        private String name;
        private String companyBankAccount;
    }

}

And then here you go. It's simple as hell, but we have to know that we must call the object getter. I was waiting at initialization, wishing the object was being built with the value but no. Hope it helps :)

    $ch = curl_init();

    $data = array(
        'client_id' => 'xx',
        'client_secret' => 'xx',
        'redirect_uri' => $x,
        'grant_type' => 'xxx',
        'code' => $xx,
    );

    $data = http_build_query($data);

    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
    curl_setopt($ch, CURLOPT_URL, "https://example.com");
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_POST, 1);

    $output = curl_exec($ch);

(Almost) All answers are deprecated in Android P, so here is C# solution (which is easy to follow for Java developers)

public bool IsOnline(Context context)
{
    var cm = (ConnectivityManager)context.GetSystemService(Context.ConnectivityService);

    if (cm == null) return false;

    if (Build.VERSION.SdkInt < BuildVersionCodes.M)
    {
        var ni = cm.ActiveNetworkInfo;

        if (ni == null) return false;

        return ni.IsConnected && (ni.Type == ConnectivityType.Wifi || ni.Type == ConnectivityType.Mobile);
    }

    return cm.GetNetworkCapabilities(cm.ActiveNetwork).HasTransport(Android.Net.TransportType.Wifi)
        || cm.GetNetworkCapabilities(cm.ActiveNetwork).HasTransport(Android.Net.TransportType.Cellular);
}   

The key here is Android.Net.TransportType

The filter design method in accepted answer is correct, but it has a flaw. SciPy bandpass filters designed with b, a are unstable and may result in erroneous filters at higher filter orders.

Instead, use sos (second-order sections) output of filter design.

from scipy.signal import butter, sosfilt, sosfreqz

def butter_bandpass(lowcut, highcut, fs, order=5):
        nyq = 0.5 * fs
        low = lowcut / nyq
        high = highcut / nyq
        sos = butter(order, [low, high], analog=False, btype='band', output='sos')
        return sos

def butter_bandpass_filter(data, lowcut, highcut, fs, order=5):
        sos = butter_bandpass(lowcut, highcut, fs, order=order)
        y = sosfilt(sos, data)
        return y

Also, you can plot frequency response by changing

b, a = butter_bandpass(lowcut, highcut, fs, order=order)
w, h = freqz(b, a, worN=2000)

to

sos = butter_bandpass(lowcut, highcut, fs, order=order)
w, h = sosfreqz(sos, worN=2000)

For simple stuff I just use the following:

unsigned TokenizeString(const std::string& i_source,
                        const std::string& i_seperators,
                        bool i_discard_empty_tokens,
                        std::vector<std::string>& o_tokens)
{
    unsigned prev_pos = 0;
    unsigned pos = 0;
    unsigned number_of_tokens = 0;
    o_tokens.clear();
    pos = i_source.find_first_of(i_seperators, pos);
    while (pos != std::string::npos)
    {
        std::string token = i_source.substr(prev_pos, pos - prev_pos);
        if (!i_discard_empty_tokens || token != "")
        {
            o_tokens.push_back(i_source.substr(prev_pos, pos - prev_pos));
            number_of_tokens++;
        }

        pos++;
        prev_pos = pos;
        pos = i_source.find_first_of(i_seperators, pos);
    }

    if (prev_pos < i_source.length())
    {
        o_tokens.push_back(i_source.substr(prev_pos));
        number_of_tokens++;
    }

    return number_of_tokens;
}

Cowardly disclaimer: I write real-time data processing software where the data comes in through binary files, sockets, or some API call (I/O cards, camera's). I never use this function for something more complicated or time-critical than reading external configuration files on startup.

NSString *str = @"Banana";
NSData *data = [str dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:true];

To answer the question as asked (without repeating unduly what appears in other answers)

Lexers and parsers are not very different, as suggested by the accepted answer. Both are based on simple language formalisms: regular languages for lexers and, almost always, context-free (CF) languages for parsers. They both are associated with fairly simple computational models, the finite state automaton and the push-down stack automaton. Regular languages are a special case of context-free languages, so that lexers could be produced with the somewhat more complex CF technology. But it is not a good idea for at least two reasons.

A fundamental point in programming is that a system component should be buit with the most appropriate technology, so that it is easy to produce, to understand and to maintain. The technology should not be overkill (using techniques much more complex and costly than needed), nor should it be at the limit of its power, thus requiring technical contortions to achieve the desired goal.

That is why "It seems fashionable to hate regular expressions". Though they can do a lot, they sometimes require very unreadable coding to achieve it, not to mention the fact that various extensions and restrictions in implementation somewhat reduce their theoretical simplicity. Lexers do not usually do that, and are usually a simple, efficient, and appropriate technology to parse token. Using CF parsers for token would be overkill, though it is possible.

Another reason not to use CF formalism for lexers is that it might then be tempting to use the full CF power. But that might raise sructural problems regarding the reading of programs.

Fundamentally, most of the structure of program text, from which meaning is extracted, is a tree structure. It expresses how the parse sentence (program) is generated from syntax rules. Semantics is derived by compositional techniques (homomorphism for the mathematically oriented) from the way syntax rules are composed to build the parse tree. Hence the tree structure is essential. The fact that tokens are identified with a regular set based lexer does not change the situation, because CF composed with regular still gives CF (I am speaking very loosely about regular transducers, that transform a stream of characters into a stream of token).

However, CF composed with CF (via CF transducers ... sorry for the math), does not necessarily give CF, and might makes things more general, but less tractable in practice. So CF is not the appropriate tool for lexers, even though it can be used.

One of the major differences between regular and CF is that regular languages (and transducers) compose very well with almost any formalism in various ways, while CF languages (and transducers) do not, not even with themselves (with a few exceptions).

(Note that regular transducers may have others uses, such as formalization of some syntax error handling techniques.)

BNF is just a specific syntax for presenting CF grammars.

EBNF is a syntactic sugar for BNF, using the facilities of regular notation to give terser version of BNF grammars. It can always be transformed into an equivalent pure BNF.

However, the regular notation is often used in EBNF only to emphasize these parts of the syntax that correspond to the structure of lexical elements, and should be recognized with the lexer, while the rest with be rather presented in straight BNF. But it is not an absolute rule.

To summarize, the simpler structure of token is better analyzed with the simpler technology of regular languages, while the tree oriented structure of the language (of program syntax) is better handled by CF grammars.

I would suggest also looking at AHR's answer.

But this leaves a question open: Why trees?

Trees are a good basis for specifying syntax because

• they give a simple structure to the text

• there are very convenient for associating semantics with the text on the basis of that structure, with a mathematically well understood technology (compositionality via homomorphisms), as indicated above. It is a fundamental algebraic tool to define the semantics of mathematical formalisms.

Hence it is a good intermediate representation, as shown by the success of Abstract Syntax Trees (AST). Note that AST are often different from parse tree because the parsing technology used by many professionals (Such as LL or LR) applies only to a subset of CF grammars, thus forcing grammatical distorsions which are later corrected in AST. This can be avoided with more general parsing technology (based on dynamic programming) that accepts any CF grammar.

Statement about the fact that programming languages are context-sensitive (CS) rather than CF are arbitrary and disputable.

The problem is that the separation of syntax and semantics is arbitrary. Checking declarations or type agreement may be seen as either part of syntax, or part of semantics. The same would be true of gender and number agreement in natural languages. But there are natural languages where plural agreement depends on the actual semantic meaning of words, so that it does not fit well with syntax.

Many definitions of programming languages in denotational semantics place declarations and type checking in the semantics. So stating as done by Ira Baxter that CF parsers are being hacked to get a context sensitivity required by syntax is at best an arbitrary view of the situation. It may be organized as a hack in some compilers, but it does not have to be.

Also it is not just that CS parsers (in the sense used in other answers here) are hard to build, and less efficient. They are are also inadequate to express perspicuously the kinf of context-sensitivity that might be needed. And they do not naturally produce a syntactic structure (such as parse-trees) that is convenient to derive the semantics of the program, i.e. to generate the compiled code.

foo = File or Object. It is used in place of an object variable or file name.

The JSON sample you provided is not valid. Check it online with this JSON Validator http://jsonlint.com/. You need to remove the extra comma on line 59.

One you have valid json you can use this code to convert it to an array.

json_decode($json, true);

It means "don't echo the command to standard output".

Rather strangely,

echo off

will send echo off to the output! So,

@echo off

sets this automatic echo behaviour off - and stops it for all future commands, too.

after generating XML you can just Replace your XML <Marks>... content here </Marks> tags with <SubjectMarks>... content here </SubjectMarks>tag. and pass updated XML to your DB.

Edit: I here explain complete process here.

Your XML Generate Like as below.

<NewDataSet>
      <StudentMarks> 
          <StudentID>1</StudentID>
          <CourseID>100</CourseID>
          <SubjectCode>MT400</SubjectCode>
          <Marks>80</Marks>
      </StudentMarks>
      <StudentMarks> 
          <StudentID>1</StudentID>
          <CourseID>100</CourseID>
          <SubjectCode>MT400</SubjectCode>
          <Marks>79</Marks>
      </StudentMarks>
      <StudentMarks> 
          <StudentID>1</StudentID>
          <CourseID>100</CourseID>
          <SubjectCode>MT400</SubjectCode>
          <Marks>88</Marks>
      </StudentMarks>
  </NewDataSet>

Here you can assign XML to string variable like as

string strXML = DataSet.GetXML();

strXML = strXML.Replace ("<Marks>","<SubjectMarks>");
strXML = strXML.Replace ("<Marks/>","<SubjectMarks/>");

and now pass strXML To your DB. Hope it will help for you.

I came up with my own basic method which seems to work fine (so far). There's probably a dozen things some of the popular scripts address that I haven't thought of.

Note - This solution is fast and easy to implement but of course not great for performance. Definitely look into the new Intersection Observer as mentioned by Apoorv and explained by developers.google if performance is an issue.

The JQuery

$(window).scroll(function() {
    $.each($('img'), function() {
        if ( $(this).attr('data-src') && $(this).offset().top < ($(window).scrollTop() + $(window).height() + 100) ) {
            var source = $(this).data('src');
            $(this).attr('src', source);
            $(this).removeAttr('data-src');
        }
    })
})

Sample html code

<div>
    <img src="" data-src="pathtoyour/image1.jpg">
    <img src="" data-src="pathtoyour/image2.jpg">
    <img src="" data-src="pathtoyour/image3.jpg">
</div>

Explained

When the page is scrolled each image on the page is checked..

$(this).attr('data-src') - if the image has the attribute data-src

and how far those images are from the bottom of the window..

$(this).offset().top < ($(window).scrollTop() + $(window).height() + 100)

adjust the + 100 to whatever you like (- 100 for example)

var source = $(this).data('src'); - gets the value of data-src= aka the image url

$(this).attr('src', source); - puts that value into the src=

$(this).removeAttr('data-src'); - removes the data-src attribute (so your browser doesn't waste resources messing with the images that have already loaded)

Adding To Existing Code

To convert your html, in an editor just search and replace src=" with src="" data-src="

A simple CSV file should suffice

You can't access element like you did (document.frm_new_user_request). You have to use the function getElementById:

document.getElementById("frm_new_user_request")

So getting a value from an input could look like this:

var value = document.getElementById("frm_new_user_request").value

Also you can use some JavaScript framework, e.g. jQuery, which simplifies operations with DOM (Document Object Model) and also hides differences between various browsers from you.

Getting a value from an input using jQuery would look like this:

• input with ID "element": var value = $("#element).value
• input with class "element": var value = $(".element).value

PHP 7.1:

$next_date = new DateTime('next Thursday');
$stamp = $next_date->getTimestamp();

PHP manual getTimestamp()

This style:

table tr td { border: 1px solid red; }
td table tr td { border: none; }

gives me:

However, using a class is probably the right approach here.

Chrome 52+ supports alpha hex:

background: #56ff0077;

CARL LANGE also showed how to get hidden, autoplaying audio in html5 on a iOS device. Works for me.

In HTML,

<div id="hideme">
    <audio id="audioTag" controls>
        <source src="/path/to/audio.mp3">
    </audio>
</div>

with JS

<script type="text/javascript">
window.onload = function() {
    var audioEl = document.getElementById("audioTag");
    audioEl.load();
    audioEl.play();
};
</script>

In CSS,

#hideme {display: none;}

The following link explains filters in Angular extremely well. It shows how it is possible to define custom sort logic within an ng-repeat. http://toddmotto.com/everything-about-custom-filters-in-angular-js

For sorting object with properties, this is the code I have used: (Note that this sort is the standard JavaScript sort method and not specific to angular) Column Name is the name of the property on which sorting is to be performed.

self.myArray.sort(function(itemA, itemB) {
    if (self.sortOrder === "ASC") {
        return itemA[columnName] > itemB[columnName];
    } else {
        return itemA[columnName] < itemB[columnName];
    }
});

Since you are the only user:

git reset --hard HEAD@{1}
git push -f
git reset --hard HEAD@{1}

( basically, go back one commit, force push to the repo, then go back again - remove the last step if you don't care about the commit )

Without doing any changes to your local repo, you can also do something like:

git push -f origin <sha_of_previous_commit>:master

Generally, in published repos, it is safer to do git revert and then git push

class Node
{
  int data;
     Node link;

     public Node()
     {
         data=0;
         link=null;
        }

     Node ptr,start,temp;

    void create()throws  IOException
     {
         int n;
         BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
         System.out.println("Enter first data");
         this.data=Integer.parseInt(br.readLine());
         ptr=this;
         start=ptr;
         char ins ='y';
         do
         {
             System.out.println("Wanna Insert another node???");
             ins=(char)br.read();
             br.read();
             if(ins=='y')
             {
                 temp=new Node();
                 System.out.println("Enter next data");
                 temp.data=Integer.parseInt(br.readLine());
                 temp.link=null;
                 ptr.link=temp;
                 temp=null;
                 ptr=ptr.link;
                }
            }while(ins=='y');
        }

public static void main(String args[])throws IOException
     {
       Node first= new Node();
       first.create();
}
}

1. without third party library
2. no need for pre-ordering array
3. you can get any portion of the tree you want

Try this

function getUnflatten(arr,parentid){
  let output = []
  for(const obj of arr){
    if(obj.parentid == parentid)

      let children = getUnflatten(arr,obj.id)

      if(children.length){
        obj.children = children
      }
      output.push(obj)
    }
  }

  return output
 }

Test it on Jsfiddle

Short answer: you want to set the handler to a function:

elemm.onclick = function() { alert('blah'); };

Slightly longer answer: you'll have to write a few more lines of code to get that to work consistently across browsers.

The fact is that even the sligthly-longer-code that might solve that particular problem across a set of common browsers will still come with problems of its own. So if you don't care about cross-browser support, go with the totally short one. If you care about it and absolutely only want to get this one single thing working, go with a combination of addEventListener and attachEvent. If you want to be able to extensively create objects and add and remove event listeners throughout your code, and want that to work across browsers, you definitely want to delegate that responsibility to a library such as jQuery.

There are errors here :

var formTag = document.getElementsByTagName("form"), // form tag is an array
selectListItem = $('select'),
makeSelect = document.createElement('select'),
makeSelect.setAttribute("id", "groups");

The code must change to:

var formTag = document.getElementsByTagName("form");
var selectListItem = $('select');
var makeSelect = document.createElement('select');
makeSelect.setAttribute("id", "groups");

By the way, there is another error at line 129 :

var createLi.appendChild(createSubList);

Replace it with:

createLi.appendChild(createSubList);
