Programs & Examples On #Smtpclient

Based on the existing answers, here's a step-by-step guide to sending automated e-mails over SMTP, using a GMail account, from the command line, without disclosing the password.

Requirements

First, install the following software packages:

• Expect
• OpenSSL
• Core Utils (base64)

These instructions assume a Linux operating system, but should be reasonably easy to port to Windows (via Cygwin or native equivalents), or other operating system.

Authentication

Save the following shell script as authentication.sh:

#!/bin/bash

# Asks for a username and password, then spits out the encoded value for
# use with authentication against SMTP servers.

echo -n "Email (shown): "
read email
echo -n "Password (hidden): "
read -s password
echo

TEXT="\0$email\0$password"

echo -ne $TEXT | base64

Make it executable and run it as follows:

chmod +x authentication.sh
./authentication.sh

When prompted, provide your e-mail address and password. This will look something like:

Email (shown): [email protected]
Password (hidden): 
AGJvYkBnbWFpbC5jb20AYm9iaXN0aGViZXN0cGVyc29uZXZlcg==

Copy the last line (AGJ...==), as this will be used for authentication.

Notification

Save the following expect script as notify.sh (note the first line refers to the expect program):

#!/usr/bin/expect

set address "[lindex $argv 0]"
set subject "[lindex $argv 1]"
set ts_date "[lindex $argv 2]"
set ts_time "[lindex $argv 3]"

set timeout 10
spawn openssl s_client -connect smtp.gmail.com:465 -crlf -ign_eof 

expect "220" {
  send "EHLO localhost\n"

  expect "250" {
    send "AUTH PLAIN YOUR_AUTHENTICATION_CODE\n"

    expect "235" {
      send "MAIL FROM: <YOUR_EMAIL_ADDRESS>\n"

      expect "250" {
        send "RCPT TO: <$address>\n"

        expect "250" {
          send "DATA\n"

          expect "354" {
            send "Subject: $subject\n\n"
            send "Email sent on $ts_date at $ts_time.\n"
            send "\n.\n"

            expect "250" {
                send "quit\n"
            }
          }
        }
      }
    }
  }
}

Make the following changes:

1. Paste over YOUR_AUTHENTICATION_CODE with the authentication code generated by the authentication script.
2. Change YOUR_EMAIL_ADDRESS with the e-mail address used to generate the authentication code.
3. Save the file.

For example (note the angle brackets are retained for the e-mail address):

send "AUTH PLAIN AGJvYkBnbWFpbC5jb20AYm9iaXN0aGViZXN0cGVyc29uZXZlcg==\n"
send "MAIL FROM: <[email protected]>\n"

Lastly, make the notify script executable as follows:

chmod +x notify.sh

Send E-mail

Send an e-mail from the command line as follows:

./notify.sh [email protected] "Command Line" "March 14" "15:52"

The default configuration of most SMTP servers is not to relay from an untrusted source to outside domains. For example, imagine that you contact the SMTP server for foo.com and ask it to send a message to [email protected]. Because the SMTP server doesn't really know who you are, it will refuse to relay the message. If the server did do that for you, it would be considered an open relay, which is how spammers often do their thing.

If you contact the foo.com mail server and ask it to send mail to [email protected], it might let you do it. It depends on if they trust that you're who you say you are. Often, the server will try to do a reverse DNS lookup, and refuse to send mail if the IP you're sending from doesn't match the IP address of the MX record in DNS. So if you say that you're the bar.com mail server but your IP address doesn't match the MX record for bar.com, then it will refuse to deliver the message.

You'll need to talk to the administrator of that SMTP server to get the authentication information so that it will allow relay for you. You'll need to present those credentials when you contact the SMTP server. Usually it's either a user name/password, or it can use Windows permissions. Depends on the server and how it's configured.

See Unable to send emails to external domain using SMTP for an example of how to send the credentials.

Finally got working :)

using System.Net.Mail;
using System.Text;

...

// Command line argument must the the SMTP host.
SmtpClient client = new SmtpClient();
client.Port = 587;
client.Host = "smtp.gmail.com";
client.EnableSsl = true;
client.Timeout = 10000;
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.UseDefaultCredentials = false;
client.Credentials = new System.Net.NetworkCredential("[email protected]","password");

MailMessage mm = new MailMessage("[email protected]", "[email protected]", "test", "test");
mm.BodyEncoding = UTF8Encoding.UTF8;
mm.DeliveryNotificationOptions = DeliveryNotificationOptions.OnFailure;

client.Send(mm);

sorry about poor spelling before

SmtpClient MyMail = new SmtpClient();
MailMessage MyMsg = new MailMessage();
MyMail.Host = "mail.eraygan.com";
MyMsg.Priority = MailPriority.High;
MyMsg.To.Add(new MailAddress(Mail));
MyMsg.Subject = Subject;
MyMsg.SubjectEncoding = Encoding.UTF8;
MyMsg.IsBodyHtml = true;
MyMsg.From = new MailAddress("username", "displayname");
MyMsg.BodyEncoding = Encoding.UTF8;
MyMsg.Body = Body;
MyMail.UseDefaultCredentials = false;
NetworkCredential MyCredentials = new NetworkCredential("username", "password");
MyMail.Credentials = MyCredentials;
MyMail.Send(MyMsg);

The answer I have finally found is that the SMTP service on the server is not using the same certificate as https.

The diagnostic steps I had read here make the assumption they use the same certificate and every time I've tried this in the past they have done and the diagnostic steps are exactly what I've done to solve the problem several times.

In this case those steps didn't work because the certificates in use were different, and the possibility of this is something I had never come across.

The solution is either to export the actual certificate from the server and then install it as a trusted certificate on my machine, or to get a different valid/trusted certificate for the SMTP service on the server. That is currently with our IT department who administer the servers to decide which they want to do.

Five years later (I hope this developer isn't still waiting for a fix to this..)

I had the same issue, caused by the same error: I was declaring the SmtpClient inside the loop.

The fix is simple - declare it once, outside the loop...

MailAddress mail = null;
SmtpClient client = new SmtpClient();
client.Port = 25;
client.EnableSsl = false;
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.UseDefaultCredentials = true;
client.Host = smtpAddress;       //  Enter your company's email server here!

for(int i = 0; i < number ; i++)
{
    mail = new MailMessage(iMail.from, iMail.to);
    mail.Subject = iMail.sub;
    mail.Body = iMail.body;
    mail.IsBodyHtml = true;
    mail.Priority = MailPriority.Normal;
    mail.Sender = from;
    client.Send(mail);
}
mail.Dispose();
client.Dispose();

There are two problems in your code:

• the return value of scanf must be checked
• the %d conversion does not take overflows into account (blindly applying *10 + newdigit for each consecutive numeric character)

The first value you got (-104204697) is equals to 5623125698541159 modulo 2^32; it is thus the result of an overflow (if int where 64 bits wide, no overflow would happen). The next values are uninitialized (garbage from the stack) and thus unpredictable.

The code you need could be (similar to the answer of BLUEPIXY above, with the illustration how to check the return value of scanf, the number of items successfully matched):

#include <stdio.h>

int main(int argc, char *argv[]) {
    int i, j;
    short unsigned digitArray[16];
    i = 0;
    while (
        i != sizeof(digitArray) / sizeof(digitArray[0])
     && 1 == scanf("%1hu", digitArray + i)
    ) {
        i++;
    }
    for (j = 0; j != i; j++) {
        printf("%hu\n", digitArray[j]);
    }
    return 0;
}

This is what works for me with percentage-based height and parent still growing according to children height. Works fine in Firefox, Chrome and Safari.

.parent {_x000D_
  position: relative;_x000D_
  min-height: 100%;_x000D_
}_x000D_
_x000D_
.child {_x000D_
  min-height: 100vh;_x000D_
}

<div class="parent">_x000D_
    <div class="child"></div>_x000D_
  </div>

When you run npm update in the command prompt, when it is done it will recommend you type a new command called npm fund.

When you run npm fund it will list all the modules and packages you have installed that were created by companies or organizations that need money for their IT projects. You will see a list of webpages where you can send them money. So "funds" means "Angular packages you installed that could use some money from you as an option to help support their businesses".

It's basically a list of the modules you have that need contributions or donations of money to their projects and which list websites where you can enter a credit card to help pay for them.

I had to do two things to the IIS configuration of the site/application. My issue had to do with getting net.tcp working in an IIS Web Site App:

First:

1. Right click on the IIS App name.
2. Manage Web Site
3. Advanced Settings
4. Set Enabled protocols to be "http,net.tcp"

Second:

1. Under the Actions menu on the right side of the Manager, click Bindings...
2. Click Add
3. Change type to "net.tcp"
4. Set binding information to {open port number}:*
5. OK

Change the code where you load the partial view to:

@Html.Partial("_CreateNote", new QuickNotes.Models.Note())

This is because the partial view is expecting a Note but is getting passed the model of the parent view which is the IEnumerable

Another approach is put the HTML in a separate file and mark the area to change with a placeholder [[content]] in this case. (You can also use sprintf instead of the str_replace.)

$page = 'Hello, World!';
$content = file_get_contents('html/welcome.html');
$pagecontent = str_replace('[[content]]', $content, $page);
echo($pagecontent);

Alternatively, you can just output all the PHP stuff to the screen captured in a buffer, write the HTML, and put the PHP output back into the page.

It might seem strange to write the PHP out, catch it, and then write it again, but it does mean that you can do all kinds of formatting stuff (heredoc, etc.), and test it outputs correctly without the hassle of the page template getting in the way. (The Joomla CMS does it this way, BTW.)

I.e.:

<?php
    ob_start();
    echo('Hello, World!');
    $php_output = ob_get_contents();
    ob_end_clean();
?>
<h1>My Template page says</h1>
<?php
    echo($php_output);
?>
<hr>
Template footer

You can use XMLHttpRequest, fetch API, ...

If you want to use XMLHttpRequest you can do the following

var xhr = new XMLHttpRequest();
xhr.open("POST", url, true);
xhr.setRequestHeader('Content-Type', 'application/json');
xhr.send(JSON.stringify({
    name: "Deska",
    email: "[email protected]",
    phone: "342234553"
 }));
xhr.onload = function() {
    var data = JSON.parse(this.responseText);
    console.log(data);
};

Or if you want to use fetch API

fetch(url, {
    method:"POST",
    body: JSON.stringify({
        name: "Deska",
        email: "[email protected]",
        phone: "342234553"
        })
    })
    .then(result => {
        // do something with the result
        console.log("Completed with result:", result);
    });

// array of $ids that you need to select
$ids = array('1', '2', '3', '4', '5', '6', '7', '8');

// create sql part for IN condition by imploding comma after each id
$in = '(' . implode(',', $ids) .')';

// create sql
$sql = 'SELECT * FROM products WHERE catid IN ' . $in;

// see what you get
var_dump($sql);

Update: (a short version and update missing comma)

$ids = array('1','2','3','4');
$sql = 'SELECT * FROM products WHERE catid IN (' . implode(',', $ids) . ')';

Working with Intellij, because I don't know how to set keyboard shortcut to mvn spring-boot:run -Dspring.profiles.active=dev, I have to do this:

<plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
    <configuration>
        <jvmArguments>
            -Dspring.profiles.active=dev
        </jvmArguments>
    </configuration>
</plugin>

{glue} offers much better string interpolation, see my other answer. Also, as Dainis rightfully mentions, sprintf() is not without problems.

There's also sprintf():

sprintf("Current working dir: %s", wd)

To print to the console output, use cat() or message():

cat(sprintf("Current working dir: %s\n", wd))
message(sprintf("Current working dir: %s\n", wd))

If you're in netbeans you can right click in the test method and click "Run Focused Test Method".

Inside a manager:

def delete_everything(self):
    Reporter.objects.all().delete()

def drop_table(self):
    cursor = connection.cursor()
    table_name = self.model._meta.db_table
    sql = "DROP TABLE %s;" % (table_name, )
    cursor.execute(sql)

 Intent callIntent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:"+198+","+1+","+1)); 
             startActivity(callIntent);

for multiple ordered call

This is used to DTMF calling systems. If call is drop then, you should pass more " , " between numbers.

There is a pandas function that can be applied to DateTime index in pandas data frame.

date = dataframe.index #date is the datetime index
date = dates.strftime('%Y-%m-%d') #this will return you a numpy array, element is string.
dstr = date.tolist() #this will make you numpy array into a list

the element inside the list:

u'1910-11-02'

You might need to replace the 'u'.

There might be some additional arguments that I should put into the previous functions.

I'm doing the same thing using invalidateViews() and that works for me. If you want it to invalidate immediately you could try calling postInvalidate after calling invalidateViews.

The method find will return the character position in a string. Then, if you want remove every thing from the character, do this:

mystring = "123?567"
mystring[ 0 : mystring.index("?")]

>> '123'

If you want to keep the character, add 1 to the character position.

I have done this way:

Get Compressed Bitmap from Singleton class:

ImageView imageView = (ImageView)findViewById(R.id.imageView);
Bitmap bitmap = ImageUtils.getInstant().getCompressedBitmap("Your_Image_Path_Here");
imageView.setImageBitmap(bitmap);

ImageUtils.java:

public class ImageUtils {

    public static ImageUtils mInstant;

    public static ImageUtils getInstant(){
        if(mInstant==null){
            mInstant = new ImageUtils();
        }
        return mInstant;
    }

    public  Bitmap getCompressedBitmap(String imagePath) {
        float maxHeight = 1920.0f;
        float maxWidth = 1080.0f;
        Bitmap scaledBitmap = null;
        BitmapFactory.Options options = new BitmapFactory.Options();
        options.inJustDecodeBounds = true;
        Bitmap bmp = BitmapFactory.decodeFile(imagePath, options);

        int actualHeight = options.outHeight;
        int actualWidth = options.outWidth;
        float imgRatio = (float) actualWidth / (float) actualHeight;
        float maxRatio = maxWidth / maxHeight;

        if (actualHeight > maxHeight || actualWidth > maxWidth) {
            if (imgRatio < maxRatio) {
                imgRatio = maxHeight / actualHeight;
                actualWidth = (int) (imgRatio * actualWidth);
                actualHeight = (int) maxHeight;
            } else if (imgRatio > maxRatio) {
                imgRatio = maxWidth / actualWidth;
                actualHeight = (int) (imgRatio * actualHeight);
                actualWidth = (int) maxWidth;
            } else {
                actualHeight = (int) maxHeight;
                actualWidth = (int) maxWidth;

            }
        }

        options.inSampleSize = calculateInSampleSize(options, actualWidth, actualHeight);
        options.inJustDecodeBounds = false;
        options.inDither = false;
        options.inPurgeable = true;
        options.inInputShareable = true;
        options.inTempStorage = new byte[16 * 1024];

        try {
            bmp = BitmapFactory.decodeFile(imagePath, options);
        } catch (OutOfMemoryError exception) {
            exception.printStackTrace();

        }
        try {
            scaledBitmap = Bitmap.createBitmap(actualWidth, actualHeight, Bitmap.Config.ARGB_8888);
        } catch (OutOfMemoryError exception) {
            exception.printStackTrace();
        }

        float ratioX = actualWidth / (float) options.outWidth;
        float ratioY = actualHeight / (float) options.outHeight;
        float middleX = actualWidth / 2.0f;
        float middleY = actualHeight / 2.0f;

        Matrix scaleMatrix = new Matrix();
        scaleMatrix.setScale(ratioX, ratioY, middleX, middleY);

        Canvas canvas = new Canvas(scaledBitmap);
        canvas.setMatrix(scaleMatrix);
        canvas.drawBitmap(bmp, middleX - bmp.getWidth() / 2, middleY - bmp.getHeight() / 2, new Paint(Paint.FILTER_BITMAP_FLAG));

        ExifInterface exif = null;
        try {
            exif = new ExifInterface(imagePath);
            int orientation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION, 0);
            Matrix matrix = new Matrix();
            if (orientation == 6) {
                matrix.postRotate(90);
            } else if (orientation == 3) {
                matrix.postRotate(180);
            } else if (orientation == 8) {
                matrix.postRotate(270);
            }
            scaledBitmap = Bitmap.createBitmap(scaledBitmap, 0, 0, scaledBitmap.getWidth(), scaledBitmap.getHeight(), matrix, true);
        } catch (IOException e) {
            e.printStackTrace();
        }
        ByteArrayOutputStream out = new ByteArrayOutputStream();
        scaledBitmap.compress(Bitmap.CompressFormat.JPEG, 85, out);

        byte[] byteArray = out.toByteArray();

        Bitmap updatedBitmap = BitmapFactory.decodeByteArray(byteArray, 0, byteArray.length);

        return updatedBitmap;
    }

    private int calculateInSampleSize(BitmapFactory.Options options, int reqWidth, int reqHeight) {
        final int height = options.outHeight;
        final int width = options.outWidth;
        int inSampleSize = 1;

        if (height > reqHeight || width > reqWidth) {
            final int heightRatio = Math.round((float) height / (float) reqHeight);
            final int widthRatio = Math.round((float) width / (float) reqWidth);
            inSampleSize = heightRatio < widthRatio ? heightRatio : widthRatio;
        }
        final float totalPixels = width * height;
        final float totalReqPixelsCap = reqWidth * reqHeight * 2;

        while (totalPixels / (inSampleSize * inSampleSize) > totalReqPixelsCap) {
            inSampleSize++;
        }
        return inSampleSize;
    }
}

Dimensions are same after compressing Bitmap.

How did I checked ?

Bitmap beforeBitmap = BitmapFactory.decodeFile("Your_Image_Path_Here");
Log.i("Before Compress Dimension", beforeBitmap.getWidth()+"-"+beforeBitmap.getHeight());

Bitmap afterBitmap = ImageUtils.getInstant().getCompressedBitmap("Your_Image_Path_Here");
Log.i("After Compress Dimension", afterBitmap.getWidth() + "-" + afterBitmap.getHeight());

Output:

Before Compress : Dimension: 1080-1452
After Compress : Dimension: 1080-1452

Hope this will help you.

It's an old question, however might be useful for someone like me.

lodash has _.inRange() function https://lodash.com/docs/4.17.4#inRange

Example:

_.inRange(3, 2, 4);
// => true

Please note that this method utilizes the Lodash utility library, and requires access to an installed version of Lodash.

the reason why $(string) is not working is because jquery is not finding html content between $(). Therefore you need to first parse it to html. once you have a variable in which you have parsed the html. you can then use $(string) and use all functions available on the object

You can use pandas library and reference the rows and columns like this:

import pandas as pd

input = pd.read_csv("path_to_file");

#for accessing ith row:
input.iloc[i]

#for accessing column named X
input.X

#for accessing ith row and column named X
input.iloc[i].X

I had two interfaces. First was child of other. I did following:

1. Added index signature in parent interface.
2. Used appropriate type using as keyword.

Complete code is as below:

Child Interface:

interface UVAmount {
  amount: number;
  price: number;
  quantity: number;
};

Parent Interface:

interface UVItem  {
// This is index signature which compiler is complaining about.
// Here we are mentioning key will string and value will any of the types mentioned.
  [key: string]:  UVAmount | string | number | object;

  name: string;
  initial: UVAmount;
  rating: number;
  others: object;
};

React Component:

let valueType = 'initial';

function getTotal(item: UVItem) {
// as keyword is the dealbreaker.
// If you don't use it, it will take string type by default and show errors.
  let itemValue = item[valueType] as UVAmount;

  return itemValue.price * itemValue.quantity;
}

Short answer: You can't.

You will have to use border-image property and a few images.

Use,

var url = $(this).attr('href');
window.open(url, '_blank');

Update:the href is better off being retrieved with prop since it will return the full url and it's slightly faster.

var url = $(this).prop('href');

In my experience, the fastest method is

UPDATE table_name SET field = REPLACE(field, 'foo', 'bar') WHERE field LIKE '%foo%';

The INSTR() way is the second-fastest and omitting the WHERE clause altogether is slowest, even if the column is not indexed.

Assuming SQL Server 2000, the following StackOverflow question should address your problem.

If using SQL Server 2005/2008, you can use the following code (taken from here):

select cast(replace(cast(myntext as nvarchar(max)),'find','replace') as ntext)
from myntexttable

In my case i had an overload of function that was causing this Exception, once i changed the name of my second function it ran ok, guess web server doesnot support function overloading

To format all the code in NetBeans, press Alt + Shift + F. If you want to indent lines, select the lines and press Alt + Shift + right arrow key, and to unindent, press Alt + Shift + left arrow key.

The unicode CLDR contains the postal code regex for each country. (158 regex's in total!)

• Download core.zip from http://unicode.org/Public/cldr/26.0.1/
• unzip core.zip
• Take a look at common/supplemental/postalCodeData.xml from the unzipped content (direct content: common/supplemental/postalCodeData.xml)

Google also has a web service with per-country address formatting information, including postal codes, here - http://i18napis.appspot.com/address (I found that link via http://unicode.org/review/pri180/ )

Edit

Here a copy of postalCodeData.xml regex :

In addition to the other answers (particularly by Lekakis), some string replacements can also be used in the option --log-file= as elaborated in the Valgrind's user manual.

Four replacements were available at the time of writing:

• %p: Prints the current process ID
  • valgrind --log-file="myFile-%p.dat" <application-name>
• %n: Prints file sequence number unique for the current process
  • valgrind --log-file="myFile-%p-%n.dat" <application-name>
• %q{ENV}: Prints contents of the environment variable ENV
  • valgrind --log-file="myFile-%q{HOME}.dat" <application-name>
• %%: Prints %
  • valgrind --log-file="myFile-%%.dat" <application-name>

This is not working as desired...

... have seen many use size calculations to check ...

I wanted to determine if it was open or not and I found isAcceptingText()

so this really does not answer the question as it does not address opening or closing rather more like is open or closed so it is related code that may help others in various scenarios...

in an activity

    if (((InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE)).isAcceptingText()) {
        Log.d(TAG,"Software Keyboard was shown");
    } else {
        Log.d(TAG,"Software Keyboard was not shown");
    }

in a fragment

    if (((InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE)).isAcceptingText()) {
        Log.d(TAG,"Software Keyboard was shown");
    } else {
        Log.d(TAG,"Software Keyboard was not shown");

    }

You can check like this:

int x;
cin >> x;

if (cin.fail()) {
    //Not an int.
}

Furthermore, you can continue to get input until you get an int via:

#include <iostream>



int main() {

    int x;
    std::cin >> x;
    while(std::cin.fail()) {
        std::cout << "Error" << std::endl;
        std::cin.clear();
        std::cin.ignore(256,'\n');
        std::cin >> x;
    }
    std::cout << x << std::endl;

    return 0;
}

EDIT: To address the comment below regarding input like 10abc, one could modify the loop to accept a string as an input. Then check the string for any character not a number and handle that situation accordingly. One needs not clear/ignore the input stream in that situation. Verifying the string is just numbers, convert the string back to an integer. I mean, this was just off the cuff. There might be a better way. This won't work if you're accepting floats/doubles (would have to add '.' in the search string).

#include <iostream>
#include <string>

int main() {

    std::string theInput;
    int inputAsInt;

    std::getline(std::cin, theInput);

    while(std::cin.fail() || std::cin.eof() || theInput.find_first_not_of("0123456789") != std::string::npos) {

        std::cout << "Error" << std::endl;

        if( theInput.find_first_not_of("0123456789") == std::string::npos) {
            std::cin.clear();
            std::cin.ignore(256,'\n');
        }

        std::getline(std::cin, theInput);
    }

    std::string::size_type st;
    inputAsInt = std::stoi(theInput,&st);
    std::cout << inputAsInt << std::endl;
    return 0;
}

Ajax Submit form with out page refresh by using jquery ajax method first include library jquery.js and jquery-form.js then create form in html:

<form action="postpage.php" method="POST" id="postForm" >

<div id="flash_success"></div>

name:
<input type="text" name="name" />
password:
<input type="password" name="pass" />
Email:
<input type="text" name="email" />

<input type="submit" name="btn" value="Submit" />
</form>

<script>
  var options = { 
        target:        '#flash_success',  // your response show in this ID
        beforeSubmit:  callValidationFunction,
        success:       YourResponseFunction  
    };
    // bind to the form's submit event
        jQuery('#postForm').submit(function() { 
            jQuery(this).ajaxSubmit(options); 
            return false; 
        }); 


});
function callValidationFunction()
{
 //  validation code for your form HERE
}

function YourResponseFunction(responseText, statusText, xhr, $form)
{
    if(responseText=='success')
    {
        $('#flash_success').html('Your Success Message Here!!!');
        $('body,html').animate({scrollTop: 0}, 800);

    }else
    {
        $('#flash_success').html('Error Msg Here');

    }
}
</script>

For z-index to work, you also need to give it a position:

header {
    width: 100%;
    height: 100px;
    background: url(../img/top.png) repeat-x;
    z-index: 110;
    position: relative;
}

Hello React Developers,

Instead of doing this disableHostCheck: true, in webpackDevServer.config.js. You can easily solve 'invalid host headers' error by adding a .env file to you project, add the variables HOST=0.0.0.0 and DANGEROUSLY_DISABLE_HOST_CHECK=true in .env file. If you want to make changes in webpackDevServer.config.js, you need to extract the react-scripts by using 'npm run eject' which is not recommended to do it. So the better solution is adding above mentioned variables in .env file of your project.

Happy Coding :)

Any ranking of various data structures will be at least partially tied to problem context. It would help to learn how to analyze time and space performance of algorithms. Typically, "big O notation" is used, e.g. binary search is in O(log n) time, which means that the time to search for an element is the log (in base 2, implicitly) of the number of elements. Intuitively, since every step discards half of the remaining data as irrelevant, doubling the number of elements will increases the time by 1 step. (Binary search scales rather well.) Space performance concerns how the amount of memory grows for larger data sets. Also, note that big-O notation ignores constant factors - for smaller data sets, an O(n^2) algorithm may still be faster than an O(n * log n) algorithm that has a higher constant factor. Complex algorithms often have more work to do on startup.

Besides time and space, other characteristics include whether a data structure is sorted (trees and skiplists are sorted, hash tables are not), persistence (binary trees can reuse pointers from older versions, while hash tables are modified in place), etc.

While you'll need to learn the behavior of several data structures to be able to compare them, one way to develop a sense for why they differ in performance is to closely study a few. I'd suggest comparing singly-linked lists, binary search trees, and skip lists, all of which are relatively simple, but have very different characteristics. Think about how much work it takes to find a value, add a new value, find all values in order, etc.

There are various texts on analyzing algorithms / data structure performance that people recommend, but what really made them make sense to me was learning OCaml. Dealing with complex data structures is ML's strong suit, and their behavior is much clearer when you can avoid pointers and memory management as in C. (Learning OCaml just to understand data structures is almost certainly the long way around, though. :) )

Postgres started on Linux/Unix. I suspect that reversing the slash with fix it.

\i somedir/script2.sql 

If you need to fully qualify something

\i c:/somedir/script2.sql

If that doesn't fix it, my next guess would be you need to escape the backslash.

\i somedir\\script2.sql

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

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

Update:

Two possible solutions:

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

hope this help you or Ctrl + Alt + Shift + S => select Dependencies tab and find what you need ( see my image)

SelectedValue returns the same value as SelectedItem.Value.

SelectedItem.Value and SelectedItem.Text might have different values and the performance is not a factor here, only the meanings of these properties matters.

<asp:DropDownList runat="server" ID="ddlUserTypes">
    <asp:ListItem Text="Admins" Value="1" Selected="true" />
    <asp:ListItem Text="Users" Value="2"/>
</asp:DropDownList>

Here, ddlUserTypes.SelectedItem.Value == ddlUserTypes.SelectedValue and both would return the value "1".

ddlUserTypes.SelectedItem.Text would return "Admins", which is different from ddlUserTypes.SelectedValue

edit

under the hood, SelectedValue looks like this

public virtual string SelectedValue
{
    get
    {
        int selectedIndex = this.SelectedIndex;
        if (selectedIndex >= 0)
        {
            return this.Items[selectedIndex].Value;
        }
        return string.Empty;
    }
}

and SelectedItem looks like this:

public virtual ListItem SelectedItem
{
    get
    {
        int selectedIndex = this.SelectedIndex;
        if (selectedIndex >= 0)
        {
            return this.Items[selectedIndex];
        }
        return null;
    }
}

One major difference between these two properties is that the SelectedValue has a setter also, since SelectedItem doesn't. The getter of SelectedValue is faster when writing code, and the problem of execution performance has no real reason to be discussed. Also a big advantage of SelectedValue is when using Binding expressions.

edit data binding scenario (you can't use SelectedItem.Value)

<asp:Repeater runat="server">
 <ItemTemplate>
     <asp:DropDownList ID="ddlCategories" runat="server" 
                       SelectedValue='<%# Eval("CategoryId")%>'>
     </asp:DropDownList>
 </ItemTemplate>
</asp:Repeater>

I had to install MariaDB. I am using OpenSUSE LINUX Leap 15 and had to execute these commands:

sudo zypper update
sudo zypper install mariadb mariadb-client mariadb-tools
sudo systemctl start mysql
sudo systemctl enable mysql //enable auto start at boot time3
sudo mysql_secure_installation

It is possible to provide a class or other information through AdditionalViewData - I use this where I'm allowing a user to create a form based on database fields (propertyName, editorType, and editorClass).

Based on your initial example:

@Html.EditorFor(x => x.Created, new { cssClass = "date" })

and in the custom template:

<div>
    @Html.TextBoxFor(x => x.Created, new { @class = ViewData["cssClass"] })
</div>

Let's get pedantic, because there are differences that can actually affect your code's behavior. Much of the following is taken from comments made to an "Old New Thing" article.

Sometimes the memory returned by the new operator will be initialized, and sometimes it won't depending on whether the type you're newing up is a POD (plain old data), or if it's a class that contains POD members and is using a compiler-generated default constructor.

• In C++1998 there are 2 types of initialization: zero and default
• In C++2003 a 3rd type of initialization, value initialization was added.

Assume:

struct A { int m; }; // POD
struct B { ~B(); int m; }; // non-POD, compiler generated default ctor
struct C { C() : m() {}; ~C(); int m; }; // non-POD, default-initialising m

In a C++98 compiler, the following should occur:

• new A - indeterminate value

• new A() - zero-initialize

• new B - default construct (B::m is uninitialized)

• new B() - default construct (B::m is uninitialized)

• new C - default construct (C::m is zero-initialized)

• new C() - default construct (C::m is zero-initialized)

In a C++03 conformant compiler, things should work like so:

• new A - indeterminate value

• new A() - value-initialize A, which is zero-initialization since it's a POD.

• new B - default-initializes (leaves B::m uninitialized)

• new B() - value-initializes B which zero-initializes all fields since its default ctor is compiler generated as opposed to user-defined.

• new C - default-initializes C, which calls the default ctor.

• new C() - value-initializes C, which calls the default ctor.

So in all versions of C++ there's a difference between new A and new A() because A is a POD.

And there's a difference in behavior between C++98 and C++03 for the case new B().

This is one of the dusty corners of C++ that can drive you crazy. When constructing an object, sometimes you want/need the parens, sometimes you absolutely cannot have them, and sometimes it doesn't matter.

char(36) would be a good choice. Also MySQL's UUID() function can be used which returns a 36-character text format (hex with hyphens) which can be used for retrievals of such IDs from the db.

This is something you solve in the "controller", which is the point of logicless templating.

// some function that retreived data through ajax
function( view ){

   if ( !view.avatar ) {
      // DEFAULTS can be a global settings object you define elsewhere
      // so that you don't have to maintain these values all over the place
      // in your code.
      view.avatar = DEFAULTS.AVATAR;
   }

   // do template stuff here

}

This is actually a LOT better then maintaining image url's or other media that might or might not change in your templates, but takes some getting used to. The point is to unlearn template tunnel vision, an avatar img url is bound to be used in other templates, are you going to maintain that url on X templates or a single DEFAULTS settings object? ;)

Another option is to do the following:

// augment view
view.hasAvatar = !!view.avatar;
view.noAvatar = !view.avatar;

And in the template:

{{#hasAvatar}}
    SHOW AVATAR
{{/hasAvatar}}
{{#noAvatar}}
    SHOW DEFAULT
{{/noAvatar}}

But that's going against the whole meaning of logicless templating. If that's what you want to do, you want logical templating and you should not use Mustache, though do give it yourself a fair chance of learning this concept ;)

Put this code in your activity

 if (id==R.id.uz)
    {
        LocaleHelper.setLocale(MainActivity.this, mLanguageCode);

        //It is required to recreate the activity to reflect the change in UI.
        recreate();
        return true;
    }
    if (id == R.id.ru) {

        LocaleHelper.setLocale(MainActivity.this, mLanguageCode);

        //It is required to recreate the activity to reflect the change in UI.
        recreate();
    }

I just want to add that this nearly identical post provides the very useful alternative of using an echo pipe if no force or quiet switch is available. For instance, I think it's the only way to bypass the Y/N prompt in this example.

Echo y|NETDOM COMPUTERNAME WorkComp /Add:Work-Comp

In a general sense you should first look at your command switches for /f, /q, or some variant thereof (for example, Netdom RenameComputer uses /Force, not /f). If there is no switch available, then use an echo pipe.

You can create a new file, setenv.sh (or setenv.bat) inside tomcats bin directory and add following line there

export CLASSPATH=$CLASSPATH:/XX/xx/PATH_TO_DIR

Array.prototype.sort_by = function(key_func, reverse=false){
    return this.sort( (a, b) => ( key_func(b) - key_func(a) ) * (reverse ? 1 : -1) ) 
}

Then for example if we have

var arr = [ {id: 0, balls: {red: 8,  blue: 10}},
            {id: 2, balls: {red: 6 , blue: 11}},
            {id: 1, balls: {red: 4 , blue: 15}} ]

arr.sort_by(el => el.id, reverse=true)
/* would result in
[ { id: 2, balls: {red: 6 , blue: 11 }},
  { id: 1, balls: {red: 4 , blue: 15 }},
  { id: 0, balls: {red: 8 , blue: 10 }} ]
*/

or

arr.sort_by(el => el.balls.red + el.balls.blue)
/* would result in
[ { id: 2, balls: {red: 6 , blue: 11 }},    // red + blue= 17
  { id: 0, balls: {red: 8 , blue: 10 }},    // red + blue= 18
  { id: 1, balls: {red: 4 , blue: 15 }} ]   // red + blue= 19
*/

 Create PROCEDURE  Stored_Procedure_Name_2
  (
  @param1 int = 5  ,
  @param2 varchar(max),
  @param3 varchar(max)

 )
AS


DECLARE @Table TABLE
(
   /*TABLE DEFINITION*/
   id int,
   name varchar(max),
   address varchar(max)
)

INSERT INTO @Table 
EXEC Stored_Procedure_Name_1 @param1 , @param2 = 'Raju' ,@param3 =@param3

SELECT id ,name ,address  FROM @Table  

sp_lock

When reading sp_lock information, use the OBJECT_NAME( ) function to get the name of a table from its ID number, for example:

SELECT object_name(16003073)

EDIT :

There is another proc provided by microsoft which reports objects without the ID translation : http://support.microsoft.com/kb/q255596/

My issue came from a bad query. I referenced a table in FROM the was not referenced in SELECT.

example:

   SELECT t.*,s.ticket_status as `ticket_status`
   FROM tickets_new t, ticket_status s, users u

, users u is what was causing the issue for me. Removing that solved the issue.

For reference this was in a CodeIgniter dev environment.

Look at the these pages on limits.h and float.h, which are included as part of the standard c library.

Most *nixen understand the environment variable 'http_proxy' when performing web requests.

export http_proxy=http://my-proxy-server.com:8080/
svn co http://code.sixapart.com/svn/perlball/

should do the trick. Most http libraries check for this (and other) environment variables.

This is an old post, but this worked for me

<select>_x000D_
  <option value="" disabled selected>Please select a name...</option> _x000D_
  <option>this</option>_x000D_
  <option>that</option>_x000D_
</select>

According to the official documentation @ https://github.com/electron/electron/blob/v8.0.0-beta.1/docs/api/menu.md the proper way to do this now since 7.1.2 and I have tested it on 8.0 as well is to :

const { app, Menu } = require('electron')

Menu.setApplicationMenu(null)

do a phpinfo(), and look for session.save_path. the directory there needs to have the correct permissions for the user and/or group that your webserver runs as

It's more convenient to use a session, this way you don't have to remember to set headers each time:

session = requests.Session()
session.headers.update({'User-Agent': 'Custom user agent'})

session.get('https://httpbin.org/headers')

By default, session also manages cookies for you. In case you want to disable that, see this question.

Check the default superclass's constructor. It need be public or protected.

clearfix should contain the floating elements but in your html you have added clearfix only after floating right that is your pull-right so you should do like this:

<div class="clearfix">
  <div id="sidebar">
    <ul>
      <li>A</li>
      <li>A</li>
      <li>C</li>
      <li>D</li>
      <li>E</li>
      <li>F</li>
      <li>...</li>
      <li>Z</li>
    </ul>
  </div>
  <div id="main">
    <div>
      <div class="pull-right">
        <a>RIGHT</a>
      </div>
    </div>
  <div>MOVED BELOW Z</div>
</div>

see this demo

Happy to know you solved the problem by setting overflow properties. However this is also good idea to clear the float. Where you have floated your elements you could add overflow: hidden; as you have done in your main.

Some people mentioning sc delete as an answer. This is how I did it, but it took me a while to find the <service-name> parameter.

The command sc query type= service (note, it's very particular with formatting, the space before "service" is necessary) will output a list of Windows services installed, complete with their qualified name to be used with sc delete <service-name> command.

The list is quite long so you may consider piping the output to a text file (i.e. >> C:\test.txt) and then searching through that.

The SERVICE_NAME is the one to use with sc delete <service-name> command.

IntelliJ has no option to click on a file and choose "Add to .gitignore" like Eclipse has.

The quickest way to add a file or folder to .gitignore without typos is:

1. Right-click on the file in the project browser and choose "Copy Path" (or use the keyboard shortcut that is displayed there).
2. Open the .gitignore file in your project, and paste.
3. Adjust the pasted line so that it is relative to the location of the .gitignore file.

Additional info: There is a .ignore plugin available for IntelliJ which adds a "Add to .gitignore" item to the popup menu when you right-click a file. It works like a charm.

If you are a regular Eclipse user than you might have got this error many times. The error simply says, “you’ve made changes in files in your workspace from outside eclipse”. The simplest solution would be to select the project and press F5 (Right click -> Refresh).

if you need more explanation you can read from this web site

var fields = $('form input[value=""]');
fields.val(' ');
setTimeout(function() {
    fields.val('');
}, 500);

Replace @RestController with @Controller.

I somehow had this issue after I lost internet connection. I was able to fix it by updating the Maven indexes in Eclipse and then selecting my project and updating the Snapshots/releases.

The better way is using 'background-size'.

.pnx-msg-icon .pnx-icon-msg-warning{
background-image: url("../pics/edit.png");
background-repeat: no-repeat;
background-size: 10px;
width: 10px;
height: 10px;
cursor: pointer;
}

even if your icon dimensions is bigger than 10px it will be 10px.

You have to use the jquery attribute selector. You can read more here:

http://api.jquery.com/attribute-equals-selector/

In your case it should be:

$('input[name="btnName"]')

If the form is using redirects, authentication, cookies, SSL (https), or anything else other than a totally open script expecting POST variables, you are going to start gnashing your teeth really quick. Take a look at Snoopy, which does exactly what you have in mind while removing the need to set up a lot of the overhead.

I am looking for this kind of solution for my self as well. I found reference in terms aggregation.

So, according to that following is the proper solution.

{
"aggs" : {
    "langs" : {
        "terms" : { "field" : "language",  
                    "size" : 500 }
    }
}}

But if you ran into following error:

"error": {
        "root_cause": [
            {
                "type": "illegal_argument_exception",
                "reason": "Fielddata is disabled on text fields by default. Set fielddata=true on [fastest_method] in order to load fielddata in memory by uninverting the inverted index. Note that this can however use significant memory. Alternatively use a keyword field instead."
            }
        ]}

In that case, you have to add "KEYWORD" in the request, like following:

   {
    "aggs" : {
        "langs" : {
            "terms" : { "field" : "language.keyword",  
                        "size" : 500 }
        }
    }}

For those with a git gui bent, you can also use gitk.

Right click on the commit you want to return to and select "Reset master branch to here". Then choose hard from the next menu.

JPA 2.0 doesn't support RETURN values, only calls.

My solution was. Create a FUNCTION calling PROCEDURE.

So, inside JAVA code you execute a NATIVE QUERY calling the oracle FUNCTION.

As described here: Angular NgModelController, you should provide the <input with the required controller ngModel

<input submit-required="true" ng-model="user.Name"></input>

More clarified version of above answers:

IEnumerable<IGrouping<int, ClassA>> groups = list.GroupBy(x => x.PropertyIntOfClassA);

foreach (var groupingByClassA in groups)
{
    int propertyIntOfClassA = groupingByClassA.Key;

    //iterating through values
    foreach (var classA in groupingByClassA)
    {
        int key = classA.PropertyIntOfClassA;
    }
}

Add Directory to PATH if not already exists:

set myPath=c:\mypath
For /F "Delims=" %%I In ('echo %PATH% ^| find /C /I "%myPath%"') Do set pathExists=%%I 2>Nul
If %pathExists%==0 (set PATH=%myPath%;%PATH%)

Make sure the PNGs are fully opaque before creating the video

e.g. with imagemagick, give them a black background:

convert 0.png -background black -flatten +matte 0_opaque.png

From my tests, no bitrate or codec is sufficient to make the video look good if you feed ffmpeg PNGs with transparency

This code works for me: I set values whit an INSERT and get the LAST_INSERT_ID() of this value whit a SELECT; I use java NetBeans 8.1, MySql and java.JDBC.driver

                try {

        String Query = "INSERT INTO `stock`(`stock`, `min_stock`,   
                `id_stock`) VALUES ("

                + "\"" + p.get_Stock().getStock() + "\", "
                + "\"" + p.get_Stock().getStockMinimo() + "\","
                + "" + "null" + ")";

        Statement st = miConexion.createStatement();
        st.executeUpdate(Query);

        java.sql.ResultSet rs;
        rs = st.executeQuery("Select LAST_INSERT_ID() from stock limit 1");                
        rs.next(); //para posicionar el puntero en la primer fila
        ultimo_id = rs.getInt("LAST_INSERT_ID()");
        } catch (SqlException ex) { ex.printTrace;}

Use Str() Function. It takes three arguments(the number, the number total characters to display, and the number of decimal places to display

  Select Str(12345.6789, 12, 3)

displays: ' 12345.679' ( 3 spaces, 5 digits 12345, a decimal point, and three decimal digits (679). - it rounds if it has to truncate, (unless the integer part is too large for the total size, in which case asterisks are displayed instead.)

for a Total of 12 characters, with 3 to the right of decimal point.

If you want to add the elements in a list (list2) to the end of other list (list), then you can use the list extend method

list = [1, 2, 3]
list2 = [4, 5, 6]
list.extend(list2)
print list
[1, 2, 3, 4, 5, 6]

Or if you want to concatenate two list then you can use + sign

list3 = list + list2
print list3
[1, 2, 3, 4, 5, 6]

you can use below code to get email address after ? in the URL

<?php_x000D_
if (isset($_GET['email'])) {_x000D_
    echo $_GET['email'];_x000D_
}

It's an interesting question, because it shows that there are a lot of different approaches to achieve the same result. Below I show three different implementations.

Default methods in Collection Framework: Java 8 added some methods to the collections classes, that are not directly related to the Stream API. Using these methods, you can significantly simplify the implementation of the non-stream implementation:

Collection<DataSet> convert(List<MultiDataPoint> multiDataPoints) {
    Map<String, DataSet> result = new HashMap<>();
    multiDataPoints.forEach(pt ->
        pt.keyToData.forEach((key, value) ->
            result.computeIfAbsent(
                key, k -> new DataSet(k, new ArrayList<>()))
            .dataPoints.add(new DataPoint(pt.timestamp, value))));
    return result.values();
}

Stream API with flatten and intermediate data structure: The following implementation is almost identical to the solution provided by Stuart Marks. In contrast to his solution, the following implementation uses an anonymous inner class as intermediate data structure.

Collection<DataSet> convert(List<MultiDataPoint> multiDataPoints) {
    return multiDataPoints.stream()
        .flatMap(mdp -> mdp.keyToData.entrySet().stream().map(e ->
            new Object() {
                String key = e.getKey();
                DataPoint dataPoint = new DataPoint(mdp.timestamp, e.getValue());
            }))
        .collect(
            collectingAndThen(
                groupingBy(t -> t.key, mapping(t -> t.dataPoint, toList())),
                m -> m.entrySet().stream().map(e -> new DataSet(e.getKey(), e.getValue())).collect(toList())));
}

Stream API with map merging: Instead of flattening the original data structures, you can also create a Map for each MultiDataPoint, and then merge all maps into a single map with a reduce operation. The code is a bit simpler than the above solution:

Collection<DataSet> convert(List<MultiDataPoint> multiDataPoints) {
    return multiDataPoints.stream()
        .map(mdp -> mdp.keyToData.entrySet().stream()
            .collect(toMap(e -> e.getKey(), e -> asList(new DataPoint(mdp.timestamp, e.getValue())))))
        .reduce(new HashMap<>(), mapMerger())
        .entrySet().stream()
        .map(e -> new DataSet(e.getKey(), e.getValue()))
        .collect(toList());
}

You can find an implementation of the map merger within the Collectors class. Unfortunately, it is a bit tricky to access it from the outside. Following is an alternative implementation of the map merger:

<K, V> BinaryOperator<Map<K, List<V>>> mapMerger() {
    return (lhs, rhs) -> {
        Map<K, List<V>> result = new HashMap<>();
        lhs.forEach((key, value) -> result.computeIfAbsent(key, k -> new ArrayList<>()).addAll(value));
        rhs.forEach((key, value) -> result.computeIfAbsent(key, k -> new ArrayList<>()).addAll(value));
        return result;
    };
}

change your collation. You can use utf8_general_ci that supports almost all

I strongly advice NOT to use the code:

process.setMaxListeners(0);

The warning is not there without reason. Most of the time, it is because there is an error hidden in your code. Removing the limit removes the warning, but not its cause, and prevents you from being warned of a source of resource leakage.

If you hit the limit for a legitimate reason, put a reasonable value in the function (the default is 10).

Also, to change the default, it is not necessary to mess with the EventEmitter prototype. you can set the value of defaultMaxListeners attribute like so:

require('events').EventEmitter.defaultMaxListeners = 15;

you can use window.setInterval and time must to be define in miliseconds, in below case the function will call after every single second (1000 miliseconds)

<script>
  var time = 3670;
window.setInterval(function(){

  // Time calculations for days, hours, minutes and seconds
    var h = Math.floor(time / 3600);
    var m = Math.floor(time % 3600 / 60);
    var s = Math.floor(time % 3600 % 60);

  // Display the result in the element with id="demo"
  document.getElementById("demo").innerHTML =  h + "h "
  + m + "m " + s + "s ";

  // If the count down is finished, write some text 
  if (time < 0) {
    clearInterval(x);
    document.getElementById("demo").innerHTML = "EXPIRED";
  }

  time--;
}, 1000);


</script>

In the v-model the value of the property might not be a strict boolean value and the checkbox might not 'recognise' the value as checked/unchecked. There is a neat feature in VueJS to make the conversion to true or false:

<input
  type="checkbox"
  v-model="toggle"
  true-value="yes"
  false-value="no"
>

You can do it in the following way:

 myfxn <- function(var1,var2,var3){
      var1*var2*var3

    }

    lapply(1:3,myfxn,var2=2,var3=100)

and you will get the answer:

[[1]] [1] 200

[[2]] [1] 400

[[3]] [1] 600

Check constraints are supported as of version 8.0.15 (yet to be released)

https://bugs.mysql.com/bug.php?id=3464

[23 Jan 16:24] Paul Dubois

Posted by developer: Fixed in 8.0.15.

Previously, MySQL permitted a limited form of CHECK constraint syntax, but parsed and ignored it. MySQL now implements the core features of table and column CHECK constraints, for all storage engines. Constraints are defined using CREATE TABLE and ALTER TABLE statements.

Thank goodness I found this. The following is extremely important:

<meta http-equiv="X-UA-Compatible" content="IE=9" >

Without this, none of the reports I'd been generating would work post IE9 install despite having worked great in IE8. They would show up properly in a web browser control, but there would be missing letters, jacked up white space, etc, when I called .Print(). They were just basic HTML that should be capable of being rendered even in Mosaic. heh Not sure why the IE7 compatibility mode was going haywire. Notably, you could .Print() the same page 5 times and have it be missing different letters each time. It would even carry over into PDF output, so it's definitely the browser.

None of the 'overflow' solutions worked for me. I'm coding a parallax effect with JavaScript using jQuery. In Chrome and Safari on OSX the elastic/rubber-band effect was messing up my scroll numbers, since it actually scrolls past the document's height and updates the window variables with out-of-boundary numbers. What I had to do was check if the scrolled amount was larger than the actual document's height, like so:

$(window).scroll(
    function() {
        if ($(window).scrollTop() + $(window).height() > $(document).height()) return;
        updateScroll(); // my own function to do my parallaxing stuff
    }
);

Assuming we are talking about web applications and building APIs:

One approach is to categorize files by feature, much like what a micro service architecture would look like. The biggest win in my opinion is that it is super easy to see which files relate to a feature of the application.

The best way to illustrate is through an example:

We are developing a library application. In the first version of the application, a user can:

• Search for books and see metadata of books
• Search for authors and see their books

In a second version, users can also:

• Create an account and log in
• Loan/borrow books

In a third version, users can also:

• Save a list of books they want to read/mark favorites

First we have the following structure:

books
  +- controllers
  ¦   +- booksController.js
  ¦   +- authorsController.js
  ¦
  +- entities
      +- book.js
      +- author.js

We then add on the user and loan features:

user
  +- controllers
  ¦   +- userController.js
  +- entities
  ¦   +- user.js
  +- middleware
       +- authentication.js
loan
  +- controllers
  ¦   +- loanController.js
  +- entities
      +- loan.js

And then the favorites functionality:

favorites
  +- controllers
  ¦   +- favoritesController.js
  +- entities
      +- favorite.js

For any new developer that gets handed the task to add on that the books search should also return information if any book have been marked as favorite, it's really easy to see where in the code he/she should look.

Then when the product owner sweeps in and exclaims that the favorites feature should be removed completely, it's easy to remove it.

Sorry this is a bit late but found the ideal solution for somple commands where you don't want any standard or error output (credit where it's due: http://felixmilea.com/2014/12/running-bash-commands-background-properly/)

This redirects output to null and keeps screen clear:

command &>/dev/null &

There's no supported way to do this, but won't you have to examine the files related to each installer to figure out how to actually install them after extracting them? Assuming you can spend the time to figure out which command-line applies, here are some candidate parameters that normally allow you to extract an installation.

MSI Based (may not result in a usable image for an InstallScript MSI installation):

• setup.exe /a /s /v"/qn TARGETDIR=\"choose-a-location\""

  or, to also extract prerequisites (for versions where it works),

• setup.exe /a"choose-another-location" /s /v"/qn TARGETDIR=\"choose-a-location\""

InstallScript based:

• setup.exe /s /extract_all

Suite based (may not be obvious how to install the resulting files):

• setup.exe /silent /stage_only ISRootStagePath="choose-a-location"

Ubuntu 16.04 64bit. I got the problem for apparently no reasons. The night before I watched a movie on my VideoLan instance, that night I would like to watch another one with VideoLan. VLC just didn't want to run because of the error into the question. I google a bit and I found the solution it solved my problem: from now on, VLC is runnable just like before. The solution is this comand:

sudo ln -sf /usr/lib/x86_64-linux-gnu/qt5/plugins/platforms/ /usr/bin/

I am not able to explain what are its consequencies, but I know it creates some missing symbolic link.

You can try this, which is working for my needs.

var d = new Date();
d.toLocaleTimeString().replace(/:\d{2}\s/,' ');

or

d.toLocaleString().replace(/:\d{2}\s/,' ');

From my knowledge, this is not possible.

Your browser has to have access to JS files to be able to execute them. If the browser has access, then browser's user also has access.

If you password protect your JS files, then the browser won't be able to access them, defeating the purpose of having JS in the first place.

function do_ajax(elem, mydata, filename)
{
    $.ajax({
        url: filename,
        context: elem,
        data: mydata,
        **contentType: false,
        processData: false**
        datatype: "html",
        success: function (data, textStatus, xhr) {
            elem.innerHTML = data;
        }
    });
}

Does your DLL project have any actual exports? If there are no exports, the linker will not generate an import library .lib file.

In the non-Express version of VS, the import libray name is specfied in the project settings here:

Configuration Properties/Linker/Advanced/Import Library

I assume it's the same in Express (if it even provides the ability to configure the name).

This query here will list the total size that a table takes up - clustered index, heap and all nonclustered indices:

SELECT 
    s.Name AS SchemaName,
    t.NAME AS TableName,
    p.rows AS RowCounts,
    SUM(a.total_pages) * 8 AS TotalSpaceKB, 
    SUM(a.used_pages) * 8 AS UsedSpaceKB, 
    (SUM(a.total_pages) - SUM(a.used_pages)) * 8 AS UnusedSpaceKB
FROM 
    sys.tables t
INNER JOIN 
    sys.schemas s ON s.schema_id = t.schema_id
INNER JOIN      
    sys.indexes i ON t.OBJECT_ID = i.object_id
INNER JOIN 
    sys.partitions p ON i.object_id = p.OBJECT_ID AND i.index_id = p.index_id
INNER JOIN 
    sys.allocation_units a ON p.partition_id = a.container_id
WHERE 
    t.NAME NOT LIKE 'dt%'    -- filter out system tables for diagramming
    AND t.is_ms_shipped = 0
    AND i.OBJECT_ID > 255 
GROUP BY 
    t.Name, s.Name, p.Rows
ORDER BY 
    s.Name, t.Name

If you want to separate table space from index space, you need to use AND i.index_id IN (0,1) for the table space (index_id = 0 is the heap space, index_id = 1 is the size of the clustered index = data pages) and AND i.index_id > 1 for the index-only space

The Beautiful Soup package does this immediately for you.

from bs4 import BeautifulSoup

soup = BeautifulSoup(html)
text = soup.get_text()
print(text)

You have two choices to do this.

The Quick and Dirty is selecting your files (using ctrl) in Project Explorer view, right-click them, choose Replace with... and then you choose the best option for you, from Latest from Repository, or some Branch version. After getting those files you modify them (with a space, or fix something, your call and commit them to create a newer revision.

A more clean way is choosing Merge at team menu and navigate through the wizard that will help you to recovery the old version in the actual revision.

Both commands have their command-line equivalents: svn revert and svn merge.

If you want to define an environment variable in your context base on documentation you shod define them as below

<Context ...>
  ...
  <Environment name="maxExemptions" value="10"
         type="java.lang.Integer" override="false"/>
  ...
</Context>

Also use them as below:

((Context)new InitialContext().lookup("java:comp/env")).lookup("maxExemptions")

You should get 10 as output.

curl is an extension that needs to be installed, it's got nothing to do with the PHP version.

http://www.php.net/manual/en/curl.setup.php

Coming at this almost a year later, there's a different manner in which I solved my particular problem. Since I wanted the link to be handled by my own app, there is a solution that is a bit simpler.

Besides the default intent filter, I simply let my target activity listen to ACTION_VIEW intents, and specifically, those with the scheme com.package.name

<intent-filter>
    <category android:name="android.intent.category.DEFAULT" />
    <action android:name="android.intent.action.VIEW" />
    <data android:scheme="com.package.name" />  
</intent-filter>

This means that links starting with com.package.name:// will be handled by my activity.

So all I have to do is construct a URL that contains the information I want to convey:

com.package.name://action-to-perform/id-that-might-be-needed/

In my target activity, I can retrieve this address:

Uri data = getIntent().getData();

In my example, I could simply check data for null values, because when ever it isn't null, I'll know it was invoked by means of such a link. From there, I extract the instructions I need from the url to be able to display the appropriate data.

Just in case if anyone is interested in labeling horizontal barplot graph, I modified Sharon's answer as below:

def show_values_on_bars(axs, h_v="v", space=0.4):
    def _show_on_single_plot(ax):
        if h_v == "v":
            for p in ax.patches:
                _x = p.get_x() + p.get_width() / 2
                _y = p.get_y() + p.get_height()
                value = int(p.get_height())
                ax.text(_x, _y, value, ha="center") 
        elif h_v == "h":
            for p in ax.patches:
                _x = p.get_x() + p.get_width() + float(space)
                _y = p.get_y() + p.get_height()
                value = int(p.get_width())
                ax.text(_x, _y, value, ha="left")

    if isinstance(axs, np.ndarray):
        for idx, ax in np.ndenumerate(axs):
            _show_on_single_plot(ax)
    else:
        _show_on_single_plot(axs)

Two parameters explained:

h_v - Whether the barplot is horizontal or vertical. "h" represents the horizontal barplot, "v" represents the vertical barplot.

space - The space between value text and the top edge of the bar. Only works for horizontal mode.

Example:

show_values_on_bars(sns_t, "h", 0.3)

In recent kernels (not sure since when) you can list the contents of /dev/serial to get a list of the serial ports on your system. They are actually symlinks pointing to the correct /dev/ node:

flu0@laptop:~$ ls /dev/serial/
total 0
drwxr-xr-x 2 root root 60 2011-07-20 17:12 by-id/
drwxr-xr-x 2 root root 60 2011-07-20 17:12 by-path/
flu0@laptop:~$ ls /dev/serial/by-id/
total 0
lrwxrwxrwx 1 root root 13 2011-07-20 17:12 usb-Prolific_Technology_Inc._USB-Serial_Controller-if00-port0 -> ../../ttyUSB0
flu0@laptop:~$ ls /dev/serial/by-path/
total 0
lrwxrwxrwx 1 root root 13 2011-07-20 17:12 pci-0000:00:0b.0-usb-0:3:1.0-port0 -> ../../ttyUSB0

This is a USB-Serial adapter, as you can see. Note that when there are no serial ports on the system, the /dev/serial/ directory does not exists. Hope this helps :).

Short ONELINER:

<input onkeypress="return /[a-z]/i.test(event.key)" >

For all unicode letters try this regexp: /\p{L}/u (but ... this) - and here is working example :)

for me also the file_exists() function is not working properly. So I got this alternative solution. Hope this one help someone

$path = 'http://localhost/admin/public/upload/video_thumbnail/thumbnail_1564385519_0.png';

    if (@GetImageSize($path)) {
        echo 'File exits';
    } else {
        echo "File doesn't exits";
    }

I'm using Rails + Cucumber + Selenium Webdriver + PhantomJS, and I've been using a monkey-patched version of Selenium Webdriver, which keeps PhantomJS browser open between test runs.

t.Log() will not show up until after the test is complete, so if you're trying to debug a test that is hanging or performing badly it seems you need to use fmt.

Yes: that was the case up to Go 1.13 (August 2019) included.

And that was followed in golang.org issue 24929

Consider the following (silly) automated tests:

func TestFoo(t *testing.T) {
    t.Parallel()

  for i := 0; i < 15; i++ {
        t.Logf("%d", i)
        time.Sleep(3 * time.Second)
    }
}

func TestBar(t *testing.T) {
    t.Parallel()

  for i := 0; i < 15; i++ {
        t.Logf("%d", i)
        time.Sleep(2 * time.Second)
    }
}

func TestBaz(t *testing.T) {
    t.Parallel()

  for i := 0; i < 15; i++ {
        t.Logf("%d", i)
        time.Sleep(1 * time.Second)
    }
}

If I run go test -v, I get no log output until all of TestFoo is done, then no output until all of TestBar is done, and again no more output until all of TestBaz is done.
This is fine if the tests are working, but if there is some sort of bug, there are a few cases where buffering log output is problematic:

• When iterating locally, I want to be able to make a change, run my tests, see what's happening in the logs immediately to understand what's going on, hit CTRL+C to shut the test down early if necessary, make another change, re-run the tests, and so on.
  If TestFoo is slow (e.g., it's an integration test), I get no log output until the very end of the test. This significantly slows down iteration.
• If TestFoo has a bug that causes it to hang and never complete, I'd get no log output whatsoever. In these cases, t.Log and t.Logf are of no use at all.
  This makes debugging very difficult.
• Moreover, not only do I get no log output, but if the test hangs too long, either the Go test timeout kills the test after 10 minutes, or if I increase that timeout, many CI servers will also kill off tests if there is no log output after a certain amount of time (e.g., 10 minutes in CircleCI).
  So now my tests are killed and I have nothing in the logs to tell me what happened.

But for (possibly) Go 1.14 (Q1 2020): CL 127120

testing: stream log output in verbose mode

The output now is:

=== RUN   TestFoo
=== PAUSE TestFoo
=== RUN   TestBar
=== PAUSE TestBar
=== RUN   TestGaz
=== PAUSE TestGaz
=== CONT  TestFoo
    TestFoo: main_test.go:14: hello from foo

--- PASS: TestBar (1.00s)

ok      dummy/streaming-test    1.022s

It is indeed in Go 1.14, as Dave Cheney attests in "go test -v streaming output":

In Go 1.14, go test -v will stream t.Log output as it happens, rather than hoarding it til the end of the test run.

Under Go 1.14 the fmt.Println and t.Log lines are interleaved, rather than waiting for the test to complete, demonstrating that test output is streamed when go test -v is used.

Advantage, according to Dave:

This is a great quality of life improvement for integration style tests that often retry for long periods when the test is failing.
Streaming t.Log output will help Gophers debug those test failures without having to wait until the entire test times out to receive their output.

The question is tricky in java (and probably also in other language).

A Integer is a 32-bit signed data type, but Integer.toBinaryString() returns a string representation of the integer argument as an unsigned integer in base 2.

So, Integer.parseInt(Integer.toBinaryString(X),2) can generate an exception (signed vs. unsigned).

The safe way is to use Integer.toString(X,2); this will generate something less elegant:

-11110100110

But it works!!!

Either add an event listener, or have the image announce itself with onload. Then figure out the dimensions from there.

<img id="photo"
     onload='loaded(this.id)'
     src="a_really_big_file.jpg"
     alt="this is some alt text"
     title="this is some title text" />

Nick has the right answer, but I wanted to add you could also get the cell data without needing the class name

var Something = $(this).closest('tr').find('td:eq(1)').text();

:eq(#) has a zero based index (link).

Yes, you can like this:

mailto: [email protected]?subject=something

i had the same problem. finally i got the solution

before updating listview, if the soft keypad is present close it first. after that set data source and call notifydatasetchanged().

while closing keypad internally listview will update its ui. it keep calling till closing keypad. that time if data source change it willl throw this exception. if data is updating in onActivityResult, there is a chance for same error.

 InputMethodManager imm = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);
            imm.hideSoftInputFromWindow(v.getWindowToken(), 0);

        view.postDelayed(new Runnable() {
            @Override
            public void run() {
                refreshList();
            }
        },100L);

I extracted the CPU part from Open Hardware Monitor into a separated library, exposing sensors and members normally hidden into OHM. It also includes many updates (like the support for Ryzen and Xeon) because on OHM they don't accept pull requests since 2015.

Let know your opinion :)

var arr = Array.prototype.slice.call( htmlCollection )

will have the same effect using "native" code.

Edit

Since this gets a lot of views, note (per @oriol's comment) that the following more concise expression is effectively equivalent:

var arr = [].slice.call(htmlCollection);

But note per @JussiR's comment, that unlike the "verbose" form, it does create an empty, unused, and indeed unusable array instance in the process. What compilers do about this is outside the programmer's ken.

Edit

Since ECMAScript 2015 (ES 6) there is also Array.from:

var arr = Array.from(htmlCollection);

Edit

ECMAScript 2015 also provides the spread operator, which is functionally equivalent to Array.from (although note that Array.from supports a mapping function as the second argument).

var arr = [...htmlCollection];

I've confirmed that both of the above work on NodeList.

I was very reluctant to choose the path I finally decide to take because of many answers. While they add more understanding to what is SQL and its principles, I decided to become an outlaw. I was also hesitant to post my findings as for some it's more important to vent frustration to someone breaking the rules rather than understanding that there are very few universal truthes.

I have tested it extensively and, in my specific case, it was way more efficient than both using array type (generously offered by PostgreSQL) or querying another table.

Here is my answer: I have successfully implemented a list into a single field in PostgreSQL, by making use of the fixed length of each item of the list. Let say each item is a color as an ARGB hex value, it means 8 char. So you can create your array of max 10 items by multiplying by the length of each item:

ALTER product ADD color varchar(80)

In case your list items length differ you can always fill the padding with \0

NB: Obviously this is not necessarily the best approach for hex number since a list of integers would consume less storage but this is just for the purpose of illustrating this idea of array by making use of a fixed length allocated to each item.

The reason why: 1/ Very convenient: retrieve item i at substring i*n, (i +1)*n. 2/ No overhead of cross tables queries. 3/ More efficient and cost-saving on the server side. The list is like a mini blob that the client will have to split.

While I respect people following rules, many explanations are very theoretical and often fail to acknowledge that, in some specific cases, especially when aiming for cost optimal with low-latency solutions, some minor tweaks are more than welcome.

"God forbid that it is violating some holy sacred principle of SQL": Adopting a more open-minded and pragmatic approach before reciting the rules is always the way to go. Else you might end up like a candid fanatic reciting the Three Laws of Robotics before being obliterated by Skynet

I don't pretend that this solution is a breakthrough, nor that it is ideal in term of readability and database flexibility, but it can certainly give you an edge when it comes to latency.

FOR KOTLIN USERS

inside your getView(...) method if you try to start an activity through button onClickListener:

   myButton.setOnClickListener{
        val intent = Intent(this@CurrentActivity, SecondActivity::class.java)
        startActivity(intent)
   }

Pass the correct pointer for "this"

Try invoking your command with Invoke-Expression:

Invoke-Expression $cmd1

Here is a working example on my machine:

$cmd = "& 'C:\Program Files\7-zip\7z.exe' a -tzip c:\temp\test.zip c:\temp\test.txt"
Invoke-Expression $cmd

iex is an alias for Invoke-Expression so you could do:

iex $cmd1

You can do either

From a view file:

<?php echo $this->request->here() ?>">

Which will give you the absolute url from the hostname i.e. /controller/action/params

Or

<?php echo Router::url(null, true) ?> 

which should give you the full url with the hostname.

When using jQuery, it is advised to use $(this) usually. But if you know (you should learn and know) the difference, sometimes it is more convenient and quicker to use just this. For instance:

$(".myCheckboxes").change(function(){ 
    if(this.checked) 
       alert("checked"); 
});

is easier and purer than

$(".myCheckboxes").change(function(){ 
      if($(this).is(":checked")) 
         alert("checked"); 
});

In addition to the suggested,

String Text = mySpinner.getSelectedItem().toString();

You can do,

String Text = String.valueOf(mySpinner.getSelectedItem());

This will work although when embedding PHP in HTML it is better practice to use the following form:

<table>
    <?php foreach($array as $key=>$value): ?>
    <tr>
        <td><?= $key; ?></td>
    </tr>
    <?php endforeach; ?>
</table>

You can find the doc for the alternative syntax on PHP.net

This will add an image to another.

I find this package quite useful and very simple: https://github.com/amphp/parallel-functions

<?php

use function Amp\ParallelFunctions\parallelMap;
use function Amp\Promise\wait;

$responses = wait(parallelMap([
    'https://google.com/',
    'https://github.com/',
    'https://stackoverflow.com/',
], function ($url) {
    return file_get_contents($url);
}));

It will load all 3 urls in parallel. You can also use class instance methods in the closure.

For example I use Laravel extension based on this package https://github.com/spatie/laravel-collection-macros#parallelmap

Here is my code:

    /**
     * Get domains with all needed data
     */
    protected function getDomainsWithdata(): Collection
    {
        return $this->opensrs->getDomains()->parallelMap(function ($domain) {
            $contact = $this->opensrs->getDomainContact($domain);
            $contact['domain'] = $domain;
            return $contact;
        }, 10);
    }

It loads all needed data in 10 parallel threads and instead of 50 secs without async it finished in just 8 secs.

I don't try to answer all of my questions, as I believe it is too broad. Just a couple of notes:

there are cases when object construction is a task complex enough to justify its extraction to another class.

That class is in fact a Builder, rather than a Factory.

In the general case, I don't want to force the users of the factory to be restrained to dynamic allocation.

Then you could have your factory encapsulate it in a smart pointer. I believe this way you can have your cake and eat it too.

This also eliminates the issues related to return-by-value.

Conclusion: Making a factory by returning an object is indeed a solution for some cases (such as the 2-D vector previously mentioned), but still not a general replacement for constructors.

Indeed. All design patterns have their (language specific) constraints and drawbacks. It is recommended to use them only when they help you solve your problem, not for their own sake.

If you are after the "perfect" factory implementation, well, good luck.

You need to make an HTTP call to your games.json to retrieve it. Something like:

this.http.get(./app/resources/games.json).map

Not sure if it'll work in all circumstances, but in our case, we were trying to override the describe function in Jest so that we can parse the name and skip the whole describe block if it met some criteria.

Here's what worked for us:

function describe( name, callback ) {
  if ( name.includes( "skip" ) )
    return this.describe.skip( name, callback );
  else
    return this.describe( name, callback );
}

Two things that are critical here:

1. We don't use an arrow function () =>.

   Arrow functions change the reference to this and we need that to be the file's this.

2. The use of this.describe and this.describe.skip instead of just describe and describe.skip.

Again, not sure it's of value to anybody but we originally tried to get away with Matthew Crumley's excellent answer but needed to make our method a function and accept params in order to parse them in the conditional.

For any reason in Firefox even though I have return false; and myform.preventDefault(); in the function, it refreshes the page after function runs. And I don't know if this is a good practice, but it works for me, I insert javascript:this.preventDefault(); in the action attribute .

As I said, I tried all the other suggestions and they work fine in all browsers but Firefox, if you have the same issue, try adding the prevent event in the action attribute either javascript:return false; or javascript:this.preventDefault();. Do not try with javascript:void(0); which will break your code. Don't ask me why :-).

I don't think this is an elegant way to do it, but in my case I had no other choice.

Update:

If you received an error... after ajax is processed, then remove the attribute action and in the onsubmit attribute, execute your function followed by the false return:

onsubmit="functionToRun(); return false;"

I don't know why all this trouble with Firefox, but hope this works.

A lot of answers have been given, based on technical considerations, especially around performance. According to me, choice between TreeSet and HashSet matters.

But I would rather say the choice should be driven by conceptual considerations first.

If, for the objects your need to manipulate, a natural ordering does not make sense, then do not use TreeSet.
It is a sorted set, since it implements SortedSet. So it means you need to override function compareTo, which should be consistent with what returns function equals. For example if you have a set of objects of a class called Student, then I do not think a TreeSet would make sense, since there is no natural ordering between students. You can order them by their average grade, okay, but this is not a "natural ordering". Function compareTo would return 0 not only when two objects represent the same student, but also when two different students have the same grade. For the second case, equals would return false (unless you decide to make the latter return true when two different students have the same grade, which would make equals function have a misleading meaning, not to say a wrong meaning.)
Please note this consistency between equals and compareTo is optional, but strongly recommended. Otherwise the contract of interface Set is broken, making your code misleading to other people, thus also possibly leading to unexpected behavior.

This link might be a good source of information regarding this question.

Sorry for late reply.But this would work properly.

daytext=(textview)findviewById(R.id.day);

Calender c=Calender.getInstance();
SimpleDateFormat sd=new SimpleDateFormat("EEEE");
String dayofweek=sd.format(c.getTime());


daytext.setText(dayofweek);

If you want to view the file in the browser, it's also possible using a similar method to the one provided by rufo and Torxed:

Since I realized that (the very excellent) answers of this post lack of by and aggregate explanations. Here is my contribution.

BY

The by function, as stated in the documentation can be though, as a "wrapper" for tapply. The power of by arises when we want to compute a task that tapply can't handle. One example is this code:

ct <- tapply(iris$Sepal.Width , iris$Species , summary )
cb <- by(iris$Sepal.Width , iris$Species , summary )

 cb
iris$Species: setosa
   Min. 1st Qu.  Median    Mean 3rd Qu.    Max. 
  2.300   3.200   3.400   3.428   3.675   4.400 
-------------------------------------------------------------- 
iris$Species: versicolor
   Min. 1st Qu.  Median    Mean 3rd Qu.    Max. 
  2.000   2.525   2.800   2.770   3.000   3.400 
-------------------------------------------------------------- 
iris$Species: virginica
   Min. 1st Qu.  Median    Mean 3rd Qu.    Max. 
  2.200   2.800   3.000   2.974   3.175   3.800 


ct
$setosa
   Min. 1st Qu.  Median    Mean 3rd Qu.    Max. 
  2.300   3.200   3.400   3.428   3.675   4.400 

$versicolor
   Min. 1st Qu.  Median    Mean 3rd Qu.    Max. 
  2.000   2.525   2.800   2.770   3.000   3.400 

$virginica
   Min. 1st Qu.  Median    Mean 3rd Qu.    Max. 
  2.200   2.800   3.000   2.974   3.175   3.800 

If we print these two objects, ct and cb, we "essentially" have the same results and the only differences are in how they are shown and the different class attributes, respectively by for cb and array for ct.

As I've said, the power of by arises when we can't use tapply; the following code is one example:

 tapply(iris, iris$Species, summary )
Error in tapply(iris, iris$Species, summary) : 
  arguments must have same length

R says that arguments must have the same lengths, say "we want to calculate the summary of all variable in iris along the factor Species": but R just can't do that because it does not know how to handle.

With the by function R dispatch a specific method for data frame class and then let the summary function works even if the length of the first argument (and the type too) are different.

it works indeed and the result is very surprising. It is an object of class by that along Species (say, for each of them) computes the summary of each variable.

Note that if the first argument is a data frame, the dispatched function must have a method for that class of objects. For example is we use this code with the mean function we will have this code that has no sense at all:

 by(iris, iris$Species, mean)
iris$Species: setosa
[1] NA
------------------------------------------- 
iris$Species: versicolor
[1] NA
------------------------------------------- 
iris$Species: virginica

3: In mean.default(data[x, , drop = FALSE], ...) :

AGGREGATE

aggregate can be seen as another a different way of use tapply if we use it in such a way.

     Group.1     x
1     setosa 5.006
2 versicolor 5.936
3  virginica 6.588

The two immediate differences are that the second argument of aggregate must be a list while tapply can (not mandatory) be a list and that the output of aggregate is a data frame while the one of tapply is an array.

The power of aggregate is that it can handle easily subsets of the data with subset argument and that it has methods for ts objects and formula as well.

These elements make aggregate easier to work with that tapply in some situations. Here are some examples (available in documentation):

ag <- aggregate(len ~ ., data = ToothGrowth, mean)

 ag
  supp dose   len
1   OJ  0.5 13.23
2   VC  0.5  7.98
3   OJ  1.0 22.70
4   VC  1.0 16.77
5   OJ  2.0 26.06
6   VC  2.0 26.14

We can achieve the same with tapply but the syntax is slightly harder and the output (in some circumstances) less readable:

att <- tapply(ToothGrowth$len, list(ToothGrowth$dose, ToothGrowth$supp), mean)

 att
       OJ    VC
0.5 13.23  7.98
1   22.70 16.77
2   26.06 26.14

There are other times when we can't use by or tapply and we have to use aggregate.

 ag1 <- aggregate(cbind(Ozone, Temp) ~ Month, data = airquality, mean)

 ag1
  Month    Ozone     Temp
1     5 23.61538 66.73077
2     6 29.44444 78.22222
3     7 59.11538 83.88462
4     8 59.96154 83.96154
5     9 31.44828 76.89655

We cannot obtain the previous result with tapply in one call but we have to calculate the mean along Month for each elements and then combine them (also note that we have to call the na.rm = TRUE, because the formula methods of the aggregate function has by default the na.action = na.omit):

ta1 <- tapply(airquality$Ozone, airquality$Month, mean, na.rm = TRUE)
ta2 <- tapply(airquality$Temp, airquality$Month, mean, na.rm = TRUE)

 cbind(ta1, ta2)
       ta1      ta2
5 23.61538 65.54839
6 29.44444 79.10000
7 59.11538 83.90323
8 59.96154 83.96774
9 31.44828 76.90000

while with by we just can't achieve that in fact the following function call returns an error (but most likely it is related to the supplied function, mean):

by(airquality[c("Ozone", "Temp")], airquality$Month, mean, na.rm = TRUE)

Other times the results are the same and the differences are just in the class (and then how it is shown/printed and not only -- example, how to subset it) object:

byagg <- by(airquality[c("Ozone", "Temp")], airquality$Month, summary)
aggagg <- aggregate(cbind(Ozone, Temp) ~ Month, data = airquality, summary)

The previous code achieve the same goal and results, at some points what tool to use is just a matter of personal tastes and needs; the previous two objects have very different needs in terms of subsetting.

There is indeed a Groovier Way.

if(members){
    //Some work
}

does everything if members is a collection. Null check as well as empty check (Empty collections are coerced to false). Hail Groovy Truth. :)

Two ways.

i. You can put it in ApplicationController and add the filters in the controller

    class ApplicationController < ActionController::Base       def filter_method       end     end      class FirstController < ApplicationController       before_filter :filter_method     end      class SecondController < ApplicationController       before_filter :filter_method     end 

But the problem here is that this method will be added to all the controllers since all of them extend from application controller

ii. Create a parent controller and define it there

 class ParentController < ApplicationController   def filter_method   end  end  class FirstController < ParentController   before_filter :filter_method end  class SecondController < ParentController   before_filter :filter_method end 

I have named it as parent controller but you can come up with a name that fits your situation properly.

You can also define the filter method in a module and include it in the controllers where you need the filter

Below code Worked for me, I am also using UITableview class

- (id)initWithStyle:(UITableViewStyle)style
{
     self = [super initWithStyle:UITableViewStyleGrouped];

     if (self)
    {

     }
    return self;
}

Note that the approach from @AndrewMyers's answer matches the entire string to the regular expression, with the effect of anchoring the regular expression at both ends of the string using ^ and $. Example:

scala> val MY_RE = "(foo|bar).*".r
MY_RE: scala.util.matching.Regex = (foo|bar).*

scala> val result = "foo123" match { case MY_RE(m) => m; case _ => "No match" }
result: String = foo

scala> val result = "baz123" match { case MY_RE(m) => m; case _ => "No match" }
result: String = No match

scala> val result = "abcfoo123" match { case MY_RE(m) => m; case _ => "No match" }
result: String = No match

And with no .* at the end:

scala> val MY_RE2 = "(foo|bar)".r
MY_RE2: scala.util.matching.Regex = (foo|bar)

scala> val result = "foo123" match { case MY_RE2(m) => m; case _ => "No match" }
result: String = No match

These didn't work for me (SQL2008 Enterprise), I also couldn't see any running processes or users connected to the DB. Restarting the server (Right click on Sql Server in Management Studio and pick Restart) allowed me to restore the DB.

you should use :

ln -s /home/jake/doc/test/2000/something xxx

use .replace(/.*\/(\S+)\//img,"$1")

"/installers/services/".replace(/.*\/(\S+)\//img,"$1"); //--> services

"/services/".replace(/.*\/(\S+)\//img,"$1"); //--> services

Try this regex "[-.]+". The + after treats consecutive delimiter chars as one. Remove plus if you do not want this.

sudo apt-get install putty

This will automatically install the puttygen tool.

Now to convert the PPK file to be used with SSH command execute the following in terminal

puttygen mykey.ppk -O private-openssh -o my-openssh-key

Then, you can connect via SSH with:

ssh -v [email protected] -i my-openssh-key

I think this is the most comprehensive answer on the PostgreSQL wiki itself: https://wiki.postgresql.org/wiki/BinaryFilesInDB

Read the part with the title 'What is the best way to store the files in the Database?'

You can achieve this with this simple CSS/HTML:

.image-container {
    position: relative;
    width: 200px;
    height: 300px;
}
.image-container .after {
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
    display: none;
    color: #FFF;
}
.image-container:hover .after {
    display: block;
    background: rgba(0, 0, 0, .6);
}

HTML

{{ form.field_name.value }} works for me

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

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

Will not work with invocations such as

say for @arr;

or

for (@arr) {
    say;
}

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

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

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

Which now acts like this

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

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

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

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

It will now act more like perl6, like so

say @arr;
# OUTPUT
# alpha beta gamma
#

DBMS stands for "Database Management Systems" it includes all Databases. RDBMS are a special Type of DMBS . R in RDBMS implies that the database uses the Relational model. a collection of related tables in the relational model makes up a database.DBMS is used for simple and small application while RDBMS is used for applications with a huge database.DBMS are for smaller organizations where security is not concerned(i.e. DBMS does not impose any constraints) while RDBMS is quitely opposite( RDBMS define the integrity constraint for the purpose of holding ACID PROPERTY).

str.strip() returns a string with leading+trailing whitespace removed, .lstrip and .rstrip for only leading and trailing respectively.

You can always code your own button with custom graphics and a PictureBox, though it won't necessarily match the Windows theme of your users.

you have to create a custom DataGridView

`

namespace System.Windows.Forms
{
    class MyDataGridView : DataGridView
    {
        public bool PreventUserClick = false;

        public MyDataGridView()
        {

        }
        protected override void OnMouseDown(MouseEventArgs e)
        {
            if (PreventUserClick) return;

            base.OnMouseDown(e);
        }
    }
}

` note that you have to first compile the program once with the added class, before you can use the new control.

then go to The .Designer.cs and change the old DataGridView to the new one without having to mess up you previous code.

private System.Windows.Forms.DataGridView dgv; // found close to the bottom

…

private void InitializeComponent() {
    ...
    this.dgv = new System.Windows.Forms.DataGridView();
    ...
}

to (respective)

private System.Windows.Forms.MyDataGridView dgv;

this.dgv = new System.Windows.Forms.MyDataGridView();

I'm not sure for UIImage, but this kind of behaviour usually occurs when coordinates are flipped. Most of OS X coordinate systems have their origin at the lower left corner, as in Postscript and PDF. But CGImage coordinate system has its origin at the upper left corner.

Possible solutions may involve an isFlipped property or a scaleYBy:-1 affine transform.

the correct answer is good , but

OutputStreamWriter wr= new OutputStreamWriter(con.getOutputStream());
wr.write(parent.toString());

not work for me , instead of it , use :

byte[] outputBytes = rootJsonObject.getBytes("UTF-8");
OutputStream os = con.getOutputStream();
os.write(outputBytes);

A class, in Python, is an object, and just like any other object, it is an instance of "something". This "something" is what is termed as a Metaclass. This metaclass is a special type of class that creates other class's objects. Hence, metaclass is responsible for making new classes. This allows the programmer to customize the way classes are generated.

To create a metaclass, overriding of new() and init() methods is usually done. new() can be overridden to change the way objects are created, while init() can be overridden to change the way of initializing the object. Metaclass can be created by a number of ways. One of the ways is to use type() function. type() function, when called with 3 parameters, creates a metaclass. The parameters are :-

1. Class Name
2. Tuple having base classes inherited by class
3. A dictionary having all class methods and class variables

Another way of creating a metaclass comprises of 'metaclass' keyword. Define the metaclass as a simple class. In the parameters of inherited class, pass metaclass=metaclass_name

Metaclass can be specifically used in the following situations :-

1. when a particular effect has to be applied to all the subclasses
2. Automatic change of class (on creation) is required
3. By API developers

Finally, the wait is over with SQL Server 2016. They have introduced the Split string function, STRING_SPLIT:

select OtherID, cs.Value --SplitData
from yourtable
cross apply STRING_SPLIT (Data, ',') cs

All the other methods to split string like XML, Tally table, while loop, etc.. have been blown away by this STRING_SPLIT function.

Here is an excellent article with performance comparison: Performance Surprises and Assumptions: STRING_SPLIT.

For older versions, using tally table here is one split string function(best possible approach)

CREATE FUNCTION [dbo].[DelimitedSplit8K]

You can try in this way.

   for(int a=5;a>0;a--){
        int b=0;
       for(b=0;b<a;b++){
           System.out.print(" ");
       }
        for (int j=b;j<5;j++){
            System.out.print(" $ ");
        }
        System.out.println("");

    }

The above answer didn't work with Angular 6. So following is how I resolved it. Lets say this is how I defined my input box -

<input type="number" id="myTextBox" name="myTextBox"_x000D_
 [(ngModel)]="response.myTextBox"_x000D_
            #myTextBox="ngModel">

To check if the field is empty or not this should be the script.

<div *ngIf="!myTextBox.value" style="color:red;">_x000D_
 Your field is empty_x000D_
</div>

Do note the subtle difference between the above answer and this answer. I have added an additional attribute .value after my input name myTextBox. I don't know if the above answer worked for above version of Angular, but for Angular 6 this is how it should be done.

Some more explanation on why this check works; when there is no value present in the input box the default value of myTextBox.value will be undefined. As soon as you enter some text, your text becomes the new value of myTextBox.value.

When your check is !myTextBox.value it is checking that the value is undefined or not, it is equivalent to myTextBox.value == undefined.

Map object in JavaScript . This is already about 3 years old now. This map data structure retains the order in which items are inserted. With this retrieving last item will actually result in latest item inserted in the Map

This shell script also works for finding a file in a directory:

echo "enter file"

read -r a

if [ -s /home/trainee02/"$a" ]
then
    echo "yes. file is there."
else
    echo "sorry. file is not there."

Shout out to: https://boltons.readthedocs.io/en/latest/socketutils.html

It provides a buffered socket, this provides a lot of very useful functionality such as:

.recv_until()    #recv until occurrence of bytes
.recv_closed()   #recv until close
.peek()          #peek at buffer but don't pop values
.settimeout()    #configure timeout (including recv timeout)

In a function:

a += 1

will be interpreted by the compiler as assign to a => Create local variable a, which is not what you want. It will probably fail with a a not initialized error since the (local) a has indeed not been initialized:

>>> a = 1
>>> def f():
...     a += 1
... 
>>> f()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 2, in f
UnboundLocalError: local variable 'a' referenced before assignment

You might get what you want with the (very frowned upon, and for good reasons) global keyword, like so:

>>> def f():
...     global a
...     a += 1
... 
>>> a
1
>>> f()
>>> a
2

In general however, you should avoid using global variables which become extremely quickly out of hand. And this is especially true for multithreaded programs, where you don't have any synchronization mechanism for your thread1 to know when a has been modified. In short: threads are complicated, and you cannot expect to have an intuitive understanding of the order in which events are happening when two (or more) threads work on the same value. The language, compiler, OS, processor... can ALL play a role, and decide to modify the order of operations for speed, practicality or any other reason.

The proper way for this kind of thing is to use Python sharing tools (locks and friends), or better, communicate data via a Queue instead of sharing it, e.g. like this:

from threading import Thread
from queue import Queue
import time

def thread1(threadname, q):
    #read variable "a" modify by thread 2
    while True:
        a = q.get()
        if a is None: return # Poison pill
        print a

def thread2(threadname, q):
    a = 0
    for _ in xrange(10):
        a += 1
        q.put(a)
        time.sleep(1)
    q.put(None) # Poison pill

queue = Queue()
thread1 = Thread( target=thread1, args=("Thread-1", queue) )
thread2 = Thread( target=thread2, args=("Thread-2", queue) )

thread1.start()
thread2.start()
thread1.join()
thread2.join()

It seems you need DataFrame.var:

Normalized by N-1 by default. This can be changed using the ddof argument

var1 = credit_card.var()

Sample:

#random dataframe
np.random.seed(100)
credit_card = pd.DataFrame(np.random.randint(10, size=(5,5)), columns=list('ABCDE'))
print (credit_card)
   A  B  C  D  E
0  8  8  3  7  7
1  0  4  2  5  2
2  2  2  1  0  8
3  4  0  9  6  2
4  4  1  5  3  4

var1 = credit_card.var()
print (var1)
A     8.8
B    10.0
C    10.0
D     7.7
E     7.8
dtype: float64

var2 = credit_card.var(axis=1)
print (var2)
0     4.3
1     3.8
2     9.8
3    12.2
4     2.3
dtype: float64

If need numpy solutions with numpy.var:

print (np.var(credit_card.values, axis=0))
[ 7.04  8.    8.    6.16  6.24]

print (np.var(credit_card.values, axis=1))
[ 3.44  3.04  7.84  9.76  1.84]

Differences are because by default ddof=1 in pandas, but you can change it to 0:

var1 = credit_card.var(ddof=0)
print (var1)
A    7.04
B    8.00
C    8.00
D    6.16
E    6.24
dtype: float64

var2 = credit_card.var(ddof=0, axis=1)
print (var2)
0    3.44
1    3.04
2    7.84
3    9.76
4    1.84
dtype: float64

in your Project perspective, look for Application --> build.gradle and edit this lines

android { compileSdkVersion "android-N" buildToolsVersion "24.0.0 rc1"

like this:

android { compileSdkVersion 24 buildToolsVersion "23.0.3"

With Swift 5, you can choose one of the two following Playground code samples in order to animate your UILabel's text changes with some cross dissolve animation.

#1. Using UIView's transition(with:duration:options:animations:completion:) class method

import UIKit
import PlaygroundSupport

class ViewController: UIViewController {

    let label = UILabel()

    override func viewDidLoad() {

Another way to do this is to define a base (abstract) test class that your actual test classes will extend :

@RunWith(SpringRunner.class)
@SpringBootTest()
@ActiveProfiles("staging")
public abstract class BaseIntegrationTest {
}

Concrete test :

public class SampleSearchServiceTest extends BaseIntegrationTest{

    @Inject
    private SampleSearchService service;

    @Test
    public void shouldInjectService(){
        assertThat(this.service).isNotNull();
    }
} 

This allows you to extract more than just the @ActiveProfiles annotation. You could also imagine more specialised base classes for different kinds of integration tests, e.g. data access layer vs service layer, or for functional specialties (common @Before or @After methods etc).

You can use below IsValidDate():

 public static bool IsValidDate(string value, string[] dateFormats)
    {
        DateTime tempDate;
        bool validDate = DateTime.TryParseExact(value, dateFormats, DateTimeFormatInfo.InvariantInfo, DateTimeStyles.None, ref tempDate);
        if (validDate)
            return true;
        else
            return false;
    }

And you can pass in the value and date formats. For example:

var data = "02-08-2019";
var dateFormats = {"dd.MM.yyyy", "dd-MM-yyyy", "dd/MM/yyyy"}

if (IsValidDate(data, dateFormats))
{
    //Do something
}
else
{
    //Do something else
}

open your git command line

put

git config --global user.email "[email protected]"

this command on command line and change email address put your own email which those use creating accout for github

hit enter

put git config --global user.name "Your Name"

use your own name insted of your name

hit enter

Download the following jars and add it to your WEB-INF/lib directory:

• jsp-api-2.0.jar
• jstl-1.2.jar

I use __dict__

Example:

class MyObj(object):
  def __init__(self):
    self.name = 'Chuck Norris'
    self.phone = '+6661'

obj = MyObj()
print(obj.__dict__)

# Output:  
# {'phone': '+6661', 'name': 'Chuck Norris'}

After some days searching the Internet I found that this error usually occurs when an html element id has the same id as some variable in the javascript function. After changing the name of one of them my code was working fine.

In my case it was that the C: drive was out of space. Ensure that you have enough space available.

If you just want to see how your picture will look on the website without uploading it to the server or without running your website on a local server, I think a very simple solution will be to convert your picture into a Base64 and add the contents into an IMG tag or as a background-image with CSS.

Are there any libraries to do this in numpy/SciPy

Sure. You can do this without OpenCV, scikit-image or PIL.

Image resizing is basically mapping the coordinates of each pixel from the original image to its resized position.

Since the coordinates of an image must be integers (think of it as a matrix), if the mapped coordinate has decimal values, you should interpolate the pixel value to approximate it to the integer position (e.g. getting the nearest pixel to that position is known as Nearest neighbor interpolation).

All you need is a function that does this interpolation for you. SciPy has interpolate.interp2d.

You can use it to resize an image in numpy array, say arr, as follows:

W, H = arr.shape[:2]
new_W, new_H = (600,300)
xrange = lambda x: np.linspace(0, 1, x)

f = interp2d(xrange(W), xrange(H), arr, kind="linear")
new_arr = f(xrange(new_W), xrange(new_H))

Of course, if your image is RGB, you have to perform the interpolation for each channel.

If you would like to understand more, I suggest watching Resizing Images - Computerphile.

You should use destroy() to close a tkinter window.

   from Tkinter import *
   root = Tk()
   Button(root, text="Quit", command=root.destroy).pack()
   root.mainloop()

Explanation:

root.quit() The above line just Bypasses the root.mainloop() i.e root.mainloop() will still be running in background if quit() command is executed.

root.destroy() While destroy() command vanish out root.mainloop() i.e root.mainloop() stops.

So as you just want to quit the program so you should use root.destroy() as it will it stop the mainloop()`.

But if you want to run some infinite loop and you don't want to destroy your Tk window and want to execute some code after root.mainloop() line then you should use root.quit(). Ex:

from Tkinter import *
def quit():
    global root
    root.quit()

root = Tk()
while True:
    Button(root, text="Quit", command=quit).pack()
    root.mainloop()
    #do something

This may or may not help anyone, but I had a page I could not get to center correctly no matter what Css tricks I tried so I wrote a JQuery file call Center Page:

The problem occurred with zoom level of the browser, the page would shift based upon if you were 100%, 125%, 150%, etc.

The code below is in a JQuery file called centerpage.js.

From my page I had to link to JQuery and this file to get it work, even though my master page already had a link to JQuery.

<title>Home Page.</title>
<script src="Scripts/jquery-1.7.1.min.js"></script>
<script src="Scripts/centerpage.js"></script>

centerpage.js:

// centering page element
function centerPage() {
    // get body element
    var body = document.body;

    // if the body element exists
    if (body != null) {
        // get the clientWidth
        var clientWidth = body.clientWidth;

        // request data for centering
        var windowWidth = document.documentElement.clientWidth;
        var left = (windowWidth - bodyWidth) / 2;

        // this is a hack, but it works for me a better method is to determine the 
        // scale but for now it works for my needs
        if (left > 84) {
            // the zoom level is most likely around 150 or higher
            $('#MainBody').removeClass('body').addClass('body150');
        } else if (left < 100) {
            // the zoom level is most likely around 110 - 140
            $('#MainBody').removeClass('body').addClass('body125');
        }
    }
}


// CONTROLLING EVENTS IN jQuery
$(document).ready(function() {
    // center the page
    centerPage();
});

Also if you want to center a panel:

// centering panel
function centerPanel($panelControl) {
    // if the panel control exists
    if ($panelControl && $panelControl.length) {
        // request data for centering
        var windowWidth = document.documentElement.clientWidth;
        var windowHeight = document.documentElement.clientHeight;
        var panelHeight = $panelControl.height();
        var panelWidth = $panelControl.width();

        // centering
        $panelControl.css({
            'position': 'absolute',
            'top': (windowHeight - panelHeight) / 2,
            'left': (windowWidth - panelWidth) / 2
        });

        // only need force for IE6
        $('#backgroundPanel').css('height', windowHeight);
    }
}

Use the std::getline() from <string>.

 istream & getline(istream & is,std::string& str)

So, for your case it would be:

std::getline(read,x);

Uninstall the make install software when make uninstall invalid.

• make install will create file '.installed.list'
• Choose to clean up the files described in .installed.list (need to be careful if you have multiple versions)
• Case: ruby2.4 switch to ruby2.3, thinking directly delete all ruby software, and then re-make install 2.3, see: Ruby # Installation Guide
• make install -> .installed.list
• see .installed.list file, delete all install files.

BEGIN...END works, you just have to add a commented section. The easiest way to do this is to add a section name! Another route is to add a comment block. See below:

BEGIN  -- Section Name
/* 
Comment block some stuff  --end comment should be on next line
*/

 --Very long query

With Eclipse 3.7 Indigo, I found the link at http://www.eclipse.org/mpc/ which told me the download location and plugin was http://download.eclipse.org/mpc/indigo/ Which made the "Eclipse Marketplace Client" available in my Software updates after I added that address as a repository. Didn't seem to be in the core list on a fresh install.

getActionCommand()

Returns the command string associated with this action. This string allows a "modal" component to specify one of several commands, depending on its state. For example, a single button might toggle between "show details" and "hide details". The source object and the event would be the same in each case, but the command string would identify the intended action.

IMO, this is useful in case you a single command-component to fire different commands based on it's state, and using this method your handler can execute the right lines of code.

JTextField has JTextField#setActionCommand(java.lang.String) method that you can use to set the command string used for action events generated by it.

getSource()

Returns: The object on which the Event initially occurred.

We can use getSource() to identify the component and execute corresponding lines of code within an action-listener. So, we don't need to write a separate action-listener for each command-component. And since you have the reference to the component itself, you can if you need to make any changes to the component as a result of the event.

If the event was generated by the JTextField then the ActionEvent#getSource() will give you the reference to the JTextField instance itself.

you need to assign the mysql_query to a variable (eg $result), then display this variable as you would a normal result from the database.

It should be well noted that the use of live() in jQuery has been deprecated since version 1.7 and has been removed in jQuery 1.9. Instead, the use of on() is recommended.

I would highly suggest the following methodology for binding, as it solves the following potential challenges:

1. By binding the event onto document.body and passing $selector as the second argument to on(), elements can be attached, detached, added or removed from the DOM without needing to deal with re-binding or double-binding events. This is because the event is attached to document.body rather than $selector directly, which means $selector can be added, removed and added again and will never load the event bound to it.
2. By calling off() before on(), this script can live either within within the main body of the page, or within the body of an AJAX call, without having to worry about accidentally double-binding events.
3. By wrapping the script within $(function() {...}), this script can again be loaded by either the main body of the page, or within the body of an AJAX call. $(document).ready() does not get fired for AJAX requests, while $(function() {...}) does.

Here is an example:

<!DOCTYPE html>
  <head>
    <script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
    <script type="text/javascript">
      $(function() {
        var $selector = $('textarea');

        // Prevent double-binding
        // (only a potential issue if script is loaded through AJAX)
        $(document.body).off('keyup', $selector);

        // Bind to keyup events on the $selector.
        $(document.body).on('keyup', $selector, function(event) {
          if(event.keyCode == 13) { // 13 = Enter Key
            alert('enter key pressed.');
          }
        });
      });
    </script>
  </head>
  <body>

  </body>
</html>

String emailData = {"to": "[email protected]","subject":"User details","body": "The user has completed his training"
}

// Java model class
public class EmailData {
    public String to;
    public String subject;
    public String body;
}

//Final Data
Gson gson = new Gson();  
EmailData emaildata = gson.fromJson(emailData, EmailData.class);

Both answers above explain very well the question regarding string patterns. However, just in case you are working with ISO 8601 there is no need to apply DateTimeFormatter since LocalDateTime is already prepared for it:

Convert LocalDateTime to Time Zone ISO8601 String

LocalDateTime ldt = LocalDateTime.now(); 
ZonedDateTime zdt = ldt.atZone(ZoneOffset.UTC); //you might use a different zone
String iso8601 = zdt.toString();

Convert from ISO8601 String back to a LocalDateTime

String iso8601 = "2016-02-14T18:32:04.150Z";
ZonedDateTime zdt = ZonedDateTime.parse(iso8601);
LocalDateTime ldt = zdt.toLocalDateTime();

I use Netbeans 7. Choose menu File \ New project, choose Import from existing folder.

Maybe you should better use a case for such lists:

case "$cms" in
  wordpress|meganto|typo3)
    do_your_else_case
    ;;
  *)
    do_your_then_case
    ;;
esac

I think for long such lists this is better readable.

If you still prefer the if you can do it with single brackets in two ways:

if [ "$cms" != wordpress -a "$cms" != meganto -a "$cms" != typo3 ]; then

or

if [ "$cms" != wordpress ] && [ "$cms" != meganto ] && [ "$cms" != typo3 ]; then

hwloc (http://www.open-mpi.org/projects/hwloc/) is worth looking at. Though requires another library integration into your code but it can provide all the information about your processor (number of cores, the topology, etc.)

Take a look at Numeral.js. It can format numbers, currency, percentages and has support for localization.

In Bootstrap 4 the correct answer is to use the text-xs-right class.

This works because xs denotes the smallest viewport size in BS. If you wanted to, you could apply the alignment only when the viewport is medium or larger by using text-md-right.

In the latest alpha, text-xs-right has been simplified to text-right.

<div class="row">
    <div class="col-md-6">Total cost</div>
    <div class="col-md-6 text-right">$42</div>
</div>

This works for strings, integers and numeric:

SELECT CONCAT(REPLICATE('0', 4 - LEN(id)), id)

Where 4 is desired length. Works for numbers with more than 4 digits, returns empty string on NULL value.
