Programs & Examples On #Email

I had a similar issue. I had installed PHPMailer version 1.72 which is not prepared to manage SSL connections. Upgrading to last version solved the problem.

You can start from wikipedia article:

• Uppercase and lowercase English letters (a-z, A-Z)
• Digits 0 to 9
• Characters ! # $ % & ' * + - / = ? ^ _ ` { | } ~
• Character . (dot, period, full stop) provided that it is not the first or last character, and provided also that it does not appear two or more times consecutively.

If you are sending file attachments and your code works for small attachments but fails for large attachments:

If you get the error "Could not instantiate mail function" error when you try to send large emails and your PHP error log contains the message "Cannot send message: Too big" then your mail transfer agent (sendmail, postfix, exim, etc) is refusing to deliver these emails.

The solution is to configure the MTA to allow larger attachments. But this is not always possible. The alternate solution is to use SMTP. You will need access to a SMTP server (and login credentials if your SMTP server requires authentication):

$mail             = new PHPMailer();
$mail->IsSMTP();                           // telling the class to use SMTP
$mail->SMTPAuth   = true;                  // enable SMTP authentication
$mail->Host       = "mail.yourdomain.com"; // set the SMTP server
$mail->Port       = 26;                    // set the SMTP port
$mail->Username   = "yourname@yourdomain"; // SMTP account username
$mail->Password   = "yourpassword";        // SMTP account password

PHPMailer defaults to using PHP mail() function which uses settings from php.ini which normally defaults to use sendmail (or something similar). In the above example we override the default behavior.

Similar to Canavar's answer, but instead of NVelocity, I always use "StringTemplate" which I load the template from a configuration file, or load an external file using File.ReadAllText() and set the values.

It's a Java project but the C# port is solid and I've used it in several projects (just used it for email templating using the template in an external file).

Alternatives are always good.

If you want to generate your email bodies in razor, you can use Mailzory. Also, you can download the nuget package from here.

// template path
var viewPath = Path.Combine("Views/Emails", "hello.cshtml");
// read the content of template and pass it to the Email constructor
var template = File.ReadAllText(viewPath);

var email = new Email(template);

// set ViewBag properties
email.ViewBag.Name = "Johnny";
email.ViewBag.Content = "Mailzory Is Funny";

// send email
var task = email.SendAsync("[email protected]", "subject");
task.Wait()

In HTML5 you can do like this:

<form>
<input type="email" placeholder="Enter your email">
<input type="submit" value="Submit">
</form>

And when the user press submit, it automatically shows an error message like:

Use EmailMultiAlternatives and render_to_string to make use of two alternative templates (one in plain text and one in html):

from django.core.mail import EmailMultiAlternatives
from django.template import Context
from django.template.loader import render_to_string

c = Context({'username': username})    
text_content = render_to_string('mail/email.txt', c)
html_content = render_to_string('mail/email.html', c)

email = EmailMultiAlternatives('Subject', text_content)
email.attach_alternative(html_content, "text/html")
email.to = ['[email protected]']
email.send()

This is the code I ended up using:

import smtplib
from email.MIMEMultipart import MIMEMultipart
from email.MIMEBase import MIMEBase
from email import Encoders


SUBJECT = "Email Data"

msg = MIMEMultipart()
msg['Subject'] = SUBJECT 
msg['From'] = self.EMAIL_FROM
msg['To'] = ', '.join(self.EMAIL_TO)

part = MIMEBase('application', "octet-stream")
part.set_payload(open("text.txt", "rb").read())
Encoders.encode_base64(part)
    
part.add_header('Content-Disposition', 'attachment; filename="text.txt"')

msg.attach(part)

server = smtplib.SMTP(self.EMAIL_SERVER)
server.sendmail(self.EMAIL_FROM, self.EMAIL_TO, msg.as_string())

Code is much the same as Oli's post.

Code based from Binary file email attachment problem post.

Do not send email to 5,000 people using standard PHP tools. You'll get banned by most ISPs in seconds and never even know it. You should either use some mailing lists software or an Email Service Provider do to this.

It turns out the original poster's server (blueHost) has a FAQ concerning this very question.

Article 206.

This is because our servers require you (or your script) to use a properly formatted, valid From: field in the email's header. If the From: field is not formatted correctly, empty or the email address does not exist in the cPanel, the From: address will be changed to username@box###.bluehost.com.

You must change the script you are using to correctly use a valid From: header.

Examples of headers that should work would be:

From: [email protected]
From: "user" <[email protected]>

Examples of headers that will NOT work:

From: "[email protected]"
From: user @ domain.com
From: [email protected] <[email protected]>

Our servers will not accept the name for the email address and the email address to be the same. It will not accept a double declaration of the email address.

For scripts such as Joomla and Wordpress, you will need to follow their documentation for formatting the from fields properly. Wordpress will require the Mail From plugin.

Note: The email address you use must be a valid created account in the cPanel.

Two generic ways to do the same thing... I'm not aware of any specific open solutions to do this, but it'd be rather trivial to do.

You could write a daily or weekly cron/jenkins job to scrape the previous time period's email from the archive looking for your keyworkds/combinations. Sending a batch digest with what it finds, if anything.

But personally, I'd Setup a specific email account to subscribe to the various security lists you're interested in. Add a simple automated script to parse the new emails for various keywords or combinations of keywords, when it finds a match forward that email on to you/your team. Just be sure to keep the keywords list updated with new products you're using.

You could even do this with a gmail account and custom rules, which is what I currently do, but I have setup an internal inbox in the past with a simple python script to forward emails that were of interest.

Yes, according to RFC 3696 apostrophes are valid as long as they come before the @ symbol.

Images or binary data:

Intent sharingIntent = new Intent(Intent.ACTION_SEND);
sharingIntent.setType("image/jpg");
Uri uri = Uri.fromFile(new File(getFilesDir(), "foo.jpg"));
sharingIntent.putExtra(Intent.EXTRA_STREAM, uri.toString());
startActivity(Intent.createChooser(sharingIntent, "Share image using"));

or HTML:

Intent sharingIntent = new Intent(Intent.ACTION_SEND);
sharingIntent.setType("text/html");
sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, Html.fromHtml("<p>This is the text shared.</p>"));
startActivity(Intent.createChooser(sharingIntent,"Share using"));

Here is worked for me:

Subject: SomeSubject
From:Company B (me)
Reply-to:Company A
To:Company A's customers

On linux, mail utility can be used to send attachment with option "-a". Go through man pages to read about the option. For eg following code will send an attachment :

mail -s "THIS IS SUBJECT" -a attachment.txt [email protected] <<< "Hi Buddy, Please find failure reports."

Recently I had the same problem to include QR image/png in email. The QR image is a byte array which is generated using ZXing. We do not want to save it to a file because saving/reading from a file is too expensive (slow). So both of the answers above do not work for me. Here's what I did to solve this problem:

import javax.mail.util.ByteArrayDataSource;
import org.apache.commons.mail.ImageHtmlEmail;
...
ImageHtmlEmail email = new ImageHtmlEmail();
byte[] qrImageBytes = createQRCode(); // get your image byte array
ByteArrayDataSource qrImageDataSource = new ByteArrayDataSource(qrImageBytes, "image/png");
String contentId = email.embed(qrImageDataSource, "QR Image");

Let's say the contentId is "111122223333", then your HTML part should have this:

<img src="cid: 111122223333">

There's no need to convert the byte array to Base64 because Commons Mail does the conversion for you automatically. Hope this helps.

It's probably putting tabs into your message. Print out message before you pass it to sendMail.

You can add new line character in text/plain content type using %0A character code.

For example:

<a href="mailto:[email protected]?subject=Hello%20again&body=HI%20%0AThis%20is%20a%20new%20line"/>

Here is the jsfiddle

Just had this issue with an Outlook client going through a Exchange server to an external address on Windows XP. Clearing the temp files seemed to do the trick.

It looks like the class.phpmailer.php file is corrupt. I would download the latest version and try again.

I've always used phpMailer's SMTP feature:

$mail->IsSMTP();
$mail->Host = "localhost";

And if you need debug info:

$mail->SMTPDebug  = 2; // enables SMTP debug information (for testing)
                       // 1 = errors and messages
                       // 2 = messages only

Regex : ^[\\w!#$%&’*+/=?{|}~^-]+(?:\.[\w!#$%&’*+/=?{|}~^-]+)*@(?:[a-zA-Z0-9-]+\\.)+[a-zA-Z]{2,6}$

public static boolean isValidEmailId(String email) {
        String emailPattern = "^[\\w!#$%&’*+/=?`{|}~^-]+(?:\\.[\\w!#$%&’*+/=?`{|}~^-]+)*@(?:[a-zA-Z0-9-]+\\.)+[a-zA-Z]{2,6}$";
        Pattern p = Pattern.compile(emailPattern);
        Matcher m = p.matcher(email);
        return m.matches();
    }

Use Fake sendmail for Windows to send mail.

1. Create a folder named sendmail in C:\wamp\.
2. Extract these 4 files in sendmail folder: sendmail.exe, libeay32.dll, ssleay32.dll and sendmail.ini.
3. Then configure C:\wamp\sendmail\sendmail.ini:

smtp_server=smtp.gmail.com
smtp_port=465
[email protected]
auth_password=your_password

4. The above will work against a Gmail account. And then configure php.ini:

   sendmail_path = "C:\wamp\sendmail\sendmail.exe -t"

5. Now, restart Apache, and that is basically all you need to do.

Try using the verbatim operator "@" before your message:

message.Body = 
@"
FirstLine
SecondLine
"

Consider that also the distance of the text from the left margin affects on the real distance from the email body left margin..

Use this method:

 public String getUserEmail() {
    AccountManager manager = AccountManager.get(App.getInstance());
    Account[] accounts = manager.getAccountsByType("com.google");
    List<String> possibleEmails = new LinkedList<>();
    for (Account account : accounts) {
        possibleEmails.add(account.name);
    }
    if (!possibleEmails.isEmpty() && possibleEmails.get(0) != null) {
        return possibleEmails.get(0);
    }
    return "";
}

Note that this requires the GET_ACCOUNTS permission:

<uses-permission android:name="android.permission.GET_ACCOUNTS" />

Then:

editTextEmailAddress.setText(getUserEmail());

A minor update to this: a sender should never set the Return-Path: header. There's no such thing as a Return-Path: header for a message in transit. That header is set by the MTA that makes final delivery, and is generally set to the value of the 5321.From unless the local system needs some kind of quirky routing.

It's a common misunderstanding because users rarely see an email without a Return-Path: header in their mailboxes. This is because they always see delivered messages, but an MTA should never see a Return-Path: header on a message in transit. See http://tools.ietf.org/html/rfc5321#section-4.4

To get it working, I had to go to myaccount.google.com -> "connected apps & sites", and turn "Allow less secure apps" to "ON" (near the bottom of the page).

I didn't find any of the existing solutions fitting - simple HTML emails to simple plain text files.

I've opened up this repository, hope it helps someone. MIT license, by the way :)

https://github.com/RobQuistNL/SimpleHtmlToText

Example:

$myHtml = '<b>This is HTML</b><h1>Header</h1><br/><br/>Newlines';
echo (new Parser())->parseString($myHtml);

returns:

**This is HTML**
### Header ###


Newlines

that the OpenSSL extension enabled and the directory languages with "br"? first checks the data.

To send html file I have used below code in my project.

final String userID = "[email protected]";
final String userPass = "userpass";
final String emailTo = "[email protected]"

Properties props = new Properties();
props.put("mail.smtp.host", "smtp.gmail.com");
props.put("mail.smtp.socketFactory.port", "465");
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.port", "465");

Session session = Session.getDefaultInstance(props,
        new javax.mail.Authenticator() {
            protected PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication(userID, userPass);
            }
        });
try {

    Message message = new MimeMessage(session);
    message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(emailTo));
    message.setSubject("Hello, this is a test mail..");

    Multipart multipart = new MimeMultipart();
    String fileName = "fileName";

    addAttachment(multipart, fileName);

    MimeBodyPart messageBodyPart1 = new MimeBodyPart();
    messageBodyPart1.setText("No need to reply.");
    multipart.addBodyPart(messageBodyPart1);

    message.setContent(multipart);

    Transport.send(message);
    System.out.println("Email successfully sent to: " + emailTo);

} catch (MessagingException e) {
    e.printStackTrace();
}



private static void addAttachment(Multipart multipart, String fileName){
    DataSource source = null;
    File f = new File("filepath" +"/"+ fileName);
    if(f.exists() && !f.isDirectory()) {
        source = new FileDataSource("filepath" +"/"+ fileName);
        BodyPart messageBodyPart = new MimeBodyPart();
        try {
            messageBodyPart.setHeader("Content-Type", "text/html");
            messageBodyPart.setDataHandler(new DataHandler(source));
            messageBodyPart.setFileName(fileName);
            multipart.addBodyPart(messageBodyPart);
        } catch (MessagingException e) {
            e.printStackTrace();
        }
    }
}

Any script tags posted on an ASP.NET web form will cause your site to throw and unhandled exception.

You can use a asp regex validator to confirm input, just ensure you wrap your code behind method with a if(IsValid) clause in case your javascript is bypassed. If your client javascript is bypassed and script tags are posted to your asp.net form, asp.net will throw a unhandled exception.

You can use something like:

<asp:RegularExpressionValidator ID="regexEmailValid" runat="server" ValidationExpression="\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*" ControlToValidate="tbEmail" ErrorMessage="Invalid Email Format"></asp:RegularExpressionValidator>

Javascript:

var pattern = new RegExp("^[_A-Za-z0-9-]+(\\.[_A-Za-z0-9-]+)*@[A-Za-z0-9]+(\\.[A-Za-z0-9]+)*(\\.[A-Za-z]{2,})$");
var result = pattern .test(str);

The regex is not allowed for:

[email protected]
[email protected]..

Allowed for:

[email protected]
[email protected]

Source: http://www.mkyong.com/regular-expressions/10-java-regular-expression-examples-you-should-know/

I don't believe that there is a formal limit here, and I'm pretty sure there isn't any hard limit specified in the RFC either, as you found.

I think that some pretty common limitations for subject lines in general (not just e-mail) are:

• 80 Characters
• 128 Characters
• 256 Characters

Obviously, you want to come up with something that is reasonable. If you're writing an e-mail client, you may want to go with something like 256 characters, and obviously test thoroughly against big commercial servers out there to make sure they serve your mail correctly.

Hope this helps!

From Linux you can use 'swaks' which is available as an official packages on many distros including Debian/Ubuntu and Redhat/CentOS on EPEL:

swaks -f [email protected] -t [email protected] \
    --server mail.example.com

You could use "Test Mail Server Tool" to test email sending on your machine or localhost. Google and Download "Test Mail Server Tool" and set it up.

Then in your settings.py:

EMAIL_BACKEND= 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'localhost'
EMAIL_PORT = 25

From shell:

from django.core.mail import send_mail
send_mail('subject','message','sender email',['receipient email'],    fail_silently=False)

You can try Mailkit. It gives you better and advance functionality for send mail. You can find more from this Here is an example

    MimeMessage message = new MimeMessage();
    message.From.Add(new MailboxAddress("FromName", "[email protected]"));
    message.To.Add(new MailboxAddress("ToName", "[email protected]"));
    message.Subject = "MyEmailSubject";

    message.Body = new TextPart("plain")
    {
        Text = @"MyEmailBodyOnlyTextPart"
    };

    using (var client = new SmtpClient())
    {
        client.Connect("SERVER", 25); // 25 is port you can change accordingly

        // Note: since we don't have an OAuth2 token, disable
        // the XOAUTH2 authentication mechanism.
        client.AuthenticationMechanisms.Remove("XOAUTH2");

        // Note: only needed if the SMTP server requires authentication
        client.Authenticate("YOUR_USER_NAME", "YOUR_PASSWORD");

        client.Send(message);
        client.Disconnect(true);
    }

For me Just run this command first

composer dump-autoload

to add vendor folder.

then run this command

composer update --no-scripts

to update composer.

About all you can do is search DNS and ensure the domain that is in the email address has an MX record, other than that there is no reliable way of dealing with this.

Some servers may work with the rcpt-to method where you talk to the SMTP server, but it depends entirely on the configuration of the server. Another issue may be an overloaded server may return a 550 code saying user is unknown, but this is a temporary error, there is a permanent error (451 i think?) that can be returned. This depends entirely on the configuration of the server.

I personally would check for the DNS MX record, then send an email verification if the MX record exists.

If you are on Windows using SMTP, you can use error_get_last() when mail() returns false. Keep in mind this does not work with PHP's native mail() function.

$success = mail('[email protected]', 'My Subject', $message);
if (!$success) {
    $errorMessage = error_get_last()['message'];
}

With print_r(error_get_last()), you get something like this:

[type] => 2
[message] => mail(): Failed to connect to mailserver at "x.x.x.x" port 25, verify your "SMTP" and "smtp_port" setting in php.ini or use ini_set()
[file] => C:\www\X\X.php
[line] => 2

echo "This is the main body of the mail" | mail -s "Subject of the Email" [email protected] -- -f [email protected] -F "Elvis Presley"

or

echo "This is the main body of the mail" | mail -s "Subject of the Email" [email protected] -aFrom:"Elvis Presley<[email protected]>"

If you want only the email clients you should use android.content.Intent.EXTRA_EMAIL with an array. Here goes an example:

final Intent result = new Intent(android.content.Intent.ACTION_SEND);
result.setType("plain/text");
result.putExtra(android.content.Intent.EXTRA_EMAIL, new String[] { recipient });
result.putExtra(android.content.Intent.EXTRA_SUBJECT, subject);
result.putExtra(android.content.Intent.EXTRA_TEXT, body);

You can loop over recipientce like:

foreach (['[email protected]', '[email protected]'] as $recipient) {
    Mail::to($recipient)->send(new OrderShipped($order));
}

See documentation here

echo "Sending emails ..."
NOW=$(date +"%F %H:%M")
echo $NOW  " Running service" >> open_files.log
header=`echo "Service Restarting: " $NOW`


mail -s "$header" [email protected],   \
              [email protected], \ < open_files.log

Old post but as you said "why is it not using the correct certificate" I would like to offer an way to find out which SSL certificate is used for SMTP (see here) which required openssl:

openssl s_client -connect exchange01.int.contoso.com:25 -starttls smtp

This will outline the used SSL certificate for the SMTP service. Based on what you see here you can replace the wrong certificate (like you already did) with a correct one (or trust the certificate manually).

For people wanting to use the built-in .NET SmtpClient rather than the SendGrid client library (not sure if that was the OP's intent), I couldn't get it to work unless I used apikey as my username and the api key itself as the password as outlined here.

<mailSettings>
    <smtp>
        <network host="smtp.sendgrid.net" port="587" userName="apikey" password="<your key goes here>" />
    </smtp>
</mailSettings>

None of the mutt ones worked for me. It was thinking the email address was part of the attachemnt. Had to do:

echo "This is the message body" | mutt -a "/path/to/file.to.attach" -s "subject of message" -- [email protected]

I don't find any of the answers here useful, so I am providing my solution.

1. The problem is that you are using multipart/related as the content type which is not good in this case. I am using multipart/mixed and inside it multipart/alternative (it works on most clients).

2. The message structure should be as follows:

   [Headers]
   Content-type:multipart/mixed; boundary="boundary1"
   --boundary1
   Content-type:multipart/alternative; boundary="boundary2"
   --boundary2
   Content-Type: text/html; charset=ISO-8859-15
   Content-Transfer-Encoding: 7bit
   [HTML code with a href="cid:..."]
   
   --boundary2
   Content-Type: image/png;
   name="moz-screenshot.png"
   Content-Transfer-Encoding: base64
   Content-ID: <part1.06090408.01060107>
   Content-Disposition: inline; filename="moz-screenshot.png"
   [base64 image data here]
   
   --boundary2--
   --boundary1--
   

Then it will work

I know I'm joining late to the discussion, but I think this can be useful to others.

I wanted to avoid deprecated stuff and after a lot of fiddling I found a simple way to send to servers requiring Implicit SSL: use NuGet and add the MailKit package to the project. (I used VS2017 targetting .NET 4.6.2 but it should work on lower .NET versions...)

Then you'll only need to do something like this:

using MailKit.Net.Smtp;
using MimeKit;

var client = new SmtpClient();
client.Connect("server.name", 465, true);

// Note: since we don't have an OAuth2 token, disable the XOAUTH2 authentication mechanism.
client.AuthenticationMechanisms.Remove ("XOAUTH2");

if (needsUserAndPwd)
{
    // Note: only needed if the SMTP server requires authentication
    client.Authenticate (user, pwd);
}

var msg = new MimeMessage();
msg.From.Add(new MailboxAddress("[email protected]"));
msg.To  .Add(new MailboxAddress("[email protected]"));
msg.Subject = "This is a test subject";

msg.Body = new TextPart("plain") {
    Text = "This is a sample message body"
};

client.Send(msg);
client.Disconnect(true);

Of course you can also tweak it to use Explicit SSL or no transport security at all.

There is no b['body'] in python. You have to use get_payload.

if isinstance(mailEntity.get_payload(), list):
    for eachPayload in mailEntity.get_payload():
        ...do things you want...
        ...real mail body is in eachPayload.get_payload()...
else:
    ...means there is only text/plain part....
    ...use mailEntity.get_payload() to get the body...

Good Luck.

The minimum required:

import java.util.Properties;

import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.AddressException;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

public class MessageSender {

    public static void sendHardCoded() throws AddressException, MessagingException {
        String to = "[email protected]";
        final String from = "[email protected]";

        Properties properties = new Properties();
        properties.put("mail.smtp.starttls.enable", "true");
        properties.put("mail.smtp.auth", "true");
        properties.put("mail.smtp.host", "smtp.gmail.com");
        properties.put("mail.smtp.port", "587");

        Session session = Session.getInstance(properties,
                new javax.mail.Authenticator() {
                    protected PasswordAuthentication getPasswordAuthentication() {
                        return new PasswordAuthentication(from, "BeNice");
                    }
                });

        MimeMessage message = new MimeMessage(session);
        message.setFrom(new InternetAddress(from));
        message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));
        message.setSubject("Hello");
        message.setText("What's up?");

        Transport.send(message);
    }

}

cat > mail.txt <<EOL
To: <email>
Subject: <subject>
Content-Type: text/html

<html>
$(cat <report-table-*.html>)

EOL

And then:

sendmail -t < mail.txt

On Ubuntu 14.04 none of these suggestions worked. Postfix would override with the logged in system user as the sender. What worked was the following solution listed at this link --> Change outgoing mail address from root@servername - rackspace sendgrid postfix

STEPS:

1) Make sure this is set in /etc/postfix/main.cf:

   smtp_generic_maps = hash:/etc/postfix/generic

2) echo 'www-data [email protected]' >> /etc/postfix/generic

3) sudo postmap /etc/postfix/generic

4) sudo service postfix restart

I had the same problem and ended up actually using border instead of padding.

You need a SMPT Server in order for

... mail($to,$subject,$message,$headers);

to work.

You could try light weight SMTP servers like xmailer

I was facing the identical problem and followed the (very clearly spelled out) steps in Vinod's reply, however this then created a different error:

Unable to read data from the transport connection: net_io_connectionclosed

I did a bit more digging and poking around and (while I'm not sure why this worked) I solved it by:
- Going back into IIS6.0 management console
- Open SMTP Virtual Server properties
- On General tab, changing the 'IP Address:' setting back to '(All Unassigned)'

Not sure why this works, but hopefully will help out someone facing the same problem in the future.

After a full day of search, I disabled Avast for 10 minutes and Windows Firewall (important) and everything started working!

This was my error:

Mail server connection failed; nested exception is javax.mail.MessagingException: Could not convert socket to TLS; nested exception is: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target. Failed messages: javax.mail.MessagingException: Could not convert socket to TLS; nested exception is: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target  

Here is how to fix the issue in Avast 19.8.2393 by adding an exclusion to SMTP port 587 (or whichever port your application uses):

1. Open Avast

2. Click on 'Settings'

3. Click on 'Troubleshooting' and then 'Open old settings'

4. Click again on 'Troubleshooting', scroll down to 'Redirect settings' and delete the port that your app uses.

In my case, I just removed 587 from SMTP ports.

Now I am able to use Avast and also have my Windows Firewall switched on (no need to add additional exclusion for the Firewall).

Here are my application.properties e-mail properties:

###### I am using a Google App Password which I generated in my Gmail Security settings ######
spring.mail.host = smtp.gmail.com
spring.mail.port = 587
spring.mail.protocol = smtp
spring.mail.username = gmail account
spring.mail.password = password
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=true
spring.mail.properties.mail.smtp.connectiontimeout=5000
spring.mail.properties.mail.smtp.timeout=5000
spring.mail.properties.mail.smtp.writetimeout=5000

first login to your gmail account and under My account > Sign In And Security > Sign In to google, enable two step verification, then you can generate app password, and you can use that app password in .env file.

Your .env file will then look something like this

MAIL_DRIVER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=587
[email protected]
MAIL_PASSWORD=apppassword
MAIL_ENCRYPTION=tls

Don't forget to run php artisan config:cache after you make changes in your .env file.

You down with OOP?

You need to code your html using absolute path for images. By Absolute path means you have to upload the images in a server and in the src attribute of images you have to give the direct path like this <img src="http://yourdomain.com/images/example.jpg">.

Below is the PHP code for your refference :- Its taken from http://www.php.net/manual/en/function.mail.php

<?php
// multiple recipients
$to  = '[email protected]' . ', '; // note the comma
$to .= '[email protected]';

// subject
$subject = 'Birthday Reminders for August';

// message
$message = '
  <p>Here are the birthdays upcoming in August!</p>
';

// To send HTML mail, the Content-type header must be set
$headers  = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=UTF-8' . "\r\n";

// Additional headers
$headers .= 'To: Mary <[email protected]>, Kelly <[email protected]>' . "\r\n";
$headers .= 'From: Birthday Reminder <[email protected]>' . "\r\n";


// Mail it
mail($to, $subject, $message, $headers);
?>

Check out your php.ini, you can set these values there.

Here's the description in the php manual: http://php.net/manual/en/mail.configuration.php

If you want to use several different SMTP servers in your application, I recommend using a "bigger" mailing framework, p.e. Swiftmailer

Adding "\t\r\n" ( \t for TAB) instead of "\r\n" worked for me on Outlook 2010 . Note : adding 3 spaces at end of each line also do same thing but that looks like a programming hack!

It isn't possible as far as I can tell, since a link needs HTML, and mailto links don't create an HTML email.

This is probably for security as you could add javascript or iframes to this link and the email client might open up the end user for vulnerabilities.

import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText

def sender(recipients): 

    body = 'Your email content here'
    msg = MIMEMultipart()

    msg['Subject'] = 'Email Subject'
    msg['From'] = '[email protected]'
    msg['To'] = (', ').join(recipients.split(','))

    msg.attach(MIMEText(body,'plain'))

    server = smtplib.SMTP('smtp.gmail.com', 587)
    server.starttls()
    server.login('[email protected]', 'yourpassword')
    server.send_message(msg)
    server.quit()

if __name__ == '__main__':
    sender('[email protected],[email protected]')

It only worked for me with send_message function and using the join function in the list whith recipients, python 3.6.

If you are interested in html formatted email, make sure to pass Content-type: text/html; in the header. Example:

// multiple recipients
$to  = '[email protected]' . ', '; // note the comma
$to .= '[email protected]';

// subject
$subject = 'Birthday Reminders for August';

// message
$message = '
<html>
<head>
  <title>Birthday Reminders for August</title>
</head>
<body>
  <p>Here are the birthdays upcoming in August!</p>
  <table>
    <tr>
      <th>Person</th><th>Day</th><th>Month</th><th>Year</th>
    </tr>
    <tr>
      <td>Joe</td><td>3rd</td><td>August</td><td>1970</td>
    </tr>
    <tr>
      <td>Sally</td><td>17th</td><td>August</td><td>1973</td>
    </tr>
  </table>
</body>
</html>
';

// To send HTML mail, the Content-type header must be set
$headers  = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";

// Additional headers
$headers .= 'To: Mary <[email protected]>, Kelly <[email protected]>' . "\r\n";
$headers .= 'From: Birthday Reminder <[email protected]>' . "\r\n";
$headers .= 'Cc: [email protected]' . "\r\n";
$headers .= 'Bcc: [email protected]' . "\r\n";

// Mail it
mail($to, $subject, $message, $headers);

For more details, check php mail function.

First of all, you aren't forced to use an SMTP on your localhost, if you change that localhost entry into the DNS name of the MTA from your ISP provider (who will let you relay mail) it will work right away, so no messing about with your own email service. Just try to use your providers SMTP servers, it will work right away.

Per @l3x, it depends.

There are clearly two sets of general situations where the correct answer can be different, along with a third which is not as general:

a) You are a user sending private mails:

Very few modern email systems implement case sensitivity, so you are probably fine to ignore case and choose whatever case you feel like using. There is no guarantee that all your mails will be delivered - but so few mails would be negatively affected that you should not worry about it.

b) You are developing mail software:

See RFC5321 2.4 excerpt at the bottom.

When you are developing mail software, you want to be RFC-compliant. You can make your own users' email addresses case insensitive if you want to (and you probably should). But in order to be RFC compliant, you MUST treat outside addresses as case sensitive.

c) Managing business-owned lists of email addresses as an employee:

It is possible that the same email recipient is added to a list more than once - but using different case. In this situation though the addresses are technically different, it might result in a recipient receiving duplicate emails. How you treat this situation is similar to situation a) in that you are probably fine to treat them as duplicates and to remove a duplicate entry. It is better to treat these as special cases however, by sending a "reminder" mail to both addresses to ask them if the case of the email address is accurate.

From a legal standpoint, if you remove a duplicate without acknowledgement/permission from both addresses, you can be held responsible for leaking private information/authentication to an unauthorised address simply because two actually-separate recipients have the same address with different cases.

Excerpt from RFC5321 2.4:

The local-part of a mailbox MUST BE treated as case sensitive. Therefore, SMTP implementations MUST take care to preserve the case of mailbox local-parts. In particular, for some hosts, the user "smith" is different from the user "Smith". However, exploiting the case sensitivity of mailbox local-parts impedes interoperability and is discouraged.

I find this simple T-SQL query useful for returning valid e-mail addresses

SELECT email
FROM People
WHERE email LIKE '%_@__%.__%' 
    AND PATINDEX('%[^a-z,0-9,@,.,_]%', REPLACE(email, '-', 'a')) = 0

The PATINDEX bit eliminates all e-mail addresses containing characters that are not in the allowed a-z, 0-9, '@', '.', '_' & '-' set of characters.

It can be reversed to do what you want like this:

SELECT email
FROM People
WHERE NOT (email LIKE '%_@__%.__%' 
    AND PATINDEX('%[^a-z,0-9,@,.,_]%', REPLACE(email, '-', 'a')) = 0)

this will solve, it will accept empty string or exact an email id

"^$|^([\w\.\-]+)@([\w\-]+)((\.(\w){2,3})+)$"

Based on Arthur Halma's answer, I did the following that works correctly with Apple's, Android & iOS mail.

define("EMAIL_DOMAIN", "yourdomain.com");

public function send_email_html($to, $from, $subject, $html) {
  preg_match_all('~<img.*?src=.([\/.a-z0-9:_-]+).*?>~si',$html,$matches);
  $i = 0;
  $paths = array();
  foreach ($matches[1] as $img) {
    $img_old = $img;
    if(strpos($img, "http://") == false) {
      $uri = parse_url($img);
      $paths[$i]['path'] = $_SERVER['DOCUMENT_ROOT'].$uri['path'];
      $content_id = md5($img);
      $html = str_replace($img_old,'cid:'.$content_id,$html);
      $paths[$i++]['cid'] = $content_id;
    }
  }
  $uniqid   = md5(uniqid(time()));
  $boundary = "--==_mimepart_".$uniqid;

  $headers = "From: ".$from."\n".
  'Reply-to: '.$from."\n".
  'Return-Path: '.$from."\n".
  'Message-ID: <'.$uniqid.'@'.EMAIL_DOMAIN.">\n".
  'Date: '.gmdate('D, d M Y H:i:s', time())."\n".
  'Mime-Version: 1.0'."\n".
  'Content-Type: multipart/related;'."\n".
  '  boundary='.$boundary.";\n".
  '  charset=UTF-8'."\n".
  'X-Mailer: PHP/' . phpversion();

  $multipart = '';
  $multipart .= "--$boundary\n";
  $kod = 'UTF-8';
  $multipart .= "Content-Type: text/html; charset=$kod\n";
  $multipart .= "Content-Transfer-Encoding: 7-bit\n\n";
  $multipart .= "$html\n\n";
  foreach ($paths as $path) {
    if (file_exists($path['path']))
      $fp = fopen($path['path'],"r");
      if (!$fp)  {
        return false;
      }
    $imagetype = substr(strrchr($path['path'], '.' ),1);
    $file = fread($fp, filesize($path['path']));
    fclose($fp);
    $message_part = "";
    switch ($imagetype) {
      case 'png':
      case 'PNG':
            $message_part .= "Content-Type: image/png";
            break;
      case 'jpg':
      case 'jpeg':
      case 'JPG':
      case 'JPEG':
            $message_part .= "Content-Type: image/jpeg";
            break;
      case 'gif':
      case 'GIF':
            $message_part .= "Content-Type: image/gif";
            break;
    }
    $message_part .= "; file_name = \"$path\"\n";
    $message_part .= 'Content-ID: <'.$path['cid'].">\n";
    $message_part .= "Content-Transfer-Encoding: base64\n";
    $message_part .= "Content-Disposition: inline; filename = \"".basename($path['path'])."\"\n\n";
    $message_part .= chunk_split(base64_encode($file))."\n";
    $multipart .= "--$boundary\n".$message_part."\n";
  }
  $multipart .= "--$boundary--\n";
  mail($to, $subject, $multipart, $headers);
}

This is appeared as pretty easy task, as Facebook don't hiding user emails or phones from me. So here is html parsing function on PHP with cURL

/*

    Query
        user name, e-mail, phone, page etc
    Types of search
        all, people, pages, places, groups, apps, events
    Result
        Array with facebook page names ( facebook.com/{page} )

    Date    2016
*/
function facebook_search($query, $type = 'all'){
    $url = 'http://www.facebook.com/search/'.$type.'/?q='.$query;
    $user_agent = 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/48.0.2564.109 Safari/537.36';

    $c = curl_init();
    curl_setopt_array($c, array(
        CURLOPT_URL             => $url,
        CURLOPT_USERAGENT       => $user_agent,
        CURLOPT_RETURNTRANSFER  => TRUE,
        CURLOPT_FOLLOWLOCATION  => TRUE,
        CURLOPT_SSL_VERIFYPEER  => FALSE
    ));
    $data = curl_exec($c);

    preg_match_all('/href=\"https:\/\/www.facebook.com\/(([^\"\/]+)|people\/([^\"]+\/\d+))[\/]?\"/', $data, $matches);
    if($matches[3][0] != FALSE){                // facebook.com/people/name/id
        $pages = array_map(function($el){
            return explode('/', $el)[0];
        }, $matches[3]);
    } else                                      // facebook.com/name
        $pages = $matches[2];
    return array_filter(array_unique($pages));  // Removing duplicates and empty values
}

I found the answer:

$mail->AddEmbeddedImage('img/2u_cs_mini.jpg', 'logo_2u');

and on the <img> tag put src='cid:logo_2u'

The java application takes too long to respond(maybe due start-up/jvm being cold) thus you get the proxy error.

Proxy Error

The proxy server received an invalid response from an upstream server.
 The proxy server could not handle the request GET /lin/Campaignn.jsp.

As Albert Maclang said amending the http timeout configuration may fix the issue. I suspect the java application throws a 500+ error thus the apache gateway error too. You should look in the logs.

Messages have content. Content can be text, html, a DataHandler or a Multipart, and there can only be one content. Multiparts only have BodyParts but can have more than one. BodyParts, like Messages, can have content which has already been described.

A message with HTML, text and an a attachment can be viewed hierarchically like this:

message
  mainMultipart (content for message, subType="mixed")
    ->htmlAndTextBodyPart (bodyPart1 for mainMultipart)
      ->htmlAndTextMultipart (content for htmlAndTextBodyPart, subType="alternative")
        ->textBodyPart (bodyPart2 for the htmlAndTextMultipart)
          ->text (content for textBodyPart)
        ->htmlBodyPart (bodyPart1 for htmlAndTextMultipart)
          ->html (content for htmlBodyPart)
    ->fileBodyPart1 (bodyPart2 for the mainMultipart)
      ->FileDataHandler (content for fileBodyPart1 )

And the code to build such a message:

    // the parent or main part if you will
    Multipart mainMultipart = new MimeMultipart("mixed");

    // this will hold text and html and tells the client there are 2 versions of the message (html and text). presumably text
    // being the alternative to html
    Multipart htmlAndTextMultipart = new MimeMultipart("alternative");

    // set text
    MimeBodyPart textBodyPart = new MimeBodyPart();
    textBodyPart.setText(text);
    htmlAndTextMultipart.addBodyPart(textBodyPart);

    // set html (set this last per rfc1341 which states last = best)
    MimeBodyPart htmlBodyPart = new MimeBodyPart();
    htmlBodyPart.setContent(html, "text/html; charset=utf-8");
    htmlAndTextMultipart.addBodyPart(htmlBodyPart);

    // stuff the multipart into a bodypart and add the bodyPart to the mainMultipart
    MimeBodyPart htmlAndTextBodyPart = new MimeBodyPart();
    htmlAndTextBodyPart.setContent(htmlAndTextMultipart);
    mainMultipart.addBodyPart(htmlAndTextBodyPart);

    // attach file body parts directly to the mainMultipart
    MimeBodyPart filePart = new MimeBodyPart();
    FileDataSource fds = new FileDataSource("/path/to/some/file.txt");
    filePart.setDataHandler(new DataHandler(fds));
    filePart.setFileName(fds.getName());
    mainMultipart.addBodyPart(filePart);

    // set message content
    message.setContent(mainMultipart);

1. Download the Java mail jars.

2. Extract the downloaded file.

3. Copy the ".jar" file and paste it into ProjectName\WebContent\WEB-INF\lib folder

4. Right click on the Project and go to Properties

5. Select Java Build Path and then select Libraries

6. Add JARs...

7. Select the .jar file from ProjectName\WebContent\WEB-INF\lib and click OK

   that's all

In cases where you are hosting a Wordpress site on Linux and have server access you can save some headaches by installing msmtp which allows you to send via smtp from the standard php mail() function. msmtp is a simpler alternative to postfix which requires a bit more configuration.

Here are the steps:

Install msmtp

sudo apt-get install msmtp-mta ca-certificates

Create a new configuration file:

sudo nano /etc/msmtprc

...with the following configuration information:

# Set defaults.    
defaults

# Enable or disable TLS/SSL encryption.
tls on
tls_starttls on
tls_trust_file /etc/ssl/certs/ca-certificates.crt

# Set up a default account's settings.
account default
host <smtp.example.net>
port 587
auth on
user <[email protected]>
password <password>
from <[email protected]>
syslog LOG_MAIL

You need to replace the configuration data represented by everything within "<" and ">" (inclusive, remove these). For host/username/password, use your normal credentials for sending mail through your mail provider.

Tell PHP to use it

sudo nano /etc/php5/apache2/php.ini

Add this single line:

sendmail_path = /usr/bin/msmtp -t

Complete documention can be found here:

https://marlam.de/msmtp/

A combination of this http://www.webcheatsheet.com/PHP/send_email_text_html_attachment.php#attachment

with the php upload file example would work. In the upload file example instead of using move_uploaded_file to move it from the temporary folder you would just open it:

$attachment = chunk_split(base64_encode(file_get_contents($tmp_file))); 

where $tmp_file = $_FILES['userfile']['tmp_name'];

and send it as an attachment like the rest of the example.

All in one file / self contained:

<? if(isset($_POST['submit'])){
//process and email
}else{
//display form
}
?>

I think its a quick exercise to get what you need working based on the above two available examples.

P.S. It needs to get uploaded somewhere before Apache passes it along to PHP to do what it wants with it. That would be your system's temp folder by default unless it was changed in the config file.

Below the attached solution work over local machine and server.

     public static string SendMail(string bodyContent)
    {
        string sendMail = "";
        try
        {

            string fromEmail = "[email protected]";
            MailMessage mailMessage = new MailMessage(fromEmail, "[email protected]", "Subject", body);
            mailMessage.IsBodyHtml = true;
            SmtpClient smtpClient = new SmtpClient("smtp.gmail.com", 587);
            smtpClient.EnableSsl = true;
            smtpClient.UseDefaultCredentials = false;
            smtpClient.Credentials = new NetworkCredential(fromEmail, frompassword);
            smtpClient.Send(mailMessage);
        }
        catch (Exception ex)
        {
            sendMail = ex.Message.ToString();
            Console.WriteLine(ex.ToString());
        }
        return sendMail;
    }

You can also use sendmail:

/usr/sbin/sendmail [email protected] < /file/to/send

Usually a good place to start when you run into problems is the manual. The page on configuring email explains that there's a big difference between the PHP mail command running on MSWindows and on every other operating system; it's a good idea when posting a question to provide relevant information on how that part of your system is configured and what operating system it is running on.

Your PHP is configured to talk to an SMTP server - the default for an MSWindows machine, but either you have no MTA installed or it's blocking connections. While for a commercial website running your own MTA robably comes quite high on the list of things to do, it is not a trivial exercise - you really need to know what you're doing to get one configured and running securely. It would make a lot more sense in your case to use a service configured and managed by someone else.

Since you'll be connecting to a remote MTA using a gmail address, then you should probably use Gmail's server; you will need SMTP authenticaton and probably SSL support - neither of which are supported by the mail() function in PHP. There's a simple example here using swiftmailer with gmail or here's an example using phpmailer

I think you are not configured properly,

if you are using XAMPP then you can easily send mail from localhost.

for example you can configure C:\xampp\php\php.ini and c:\xampp\sendmail\sendmail.ini for gmail to send mail.

in C:\xampp\php\php.ini find extension=php_openssl.dll and remove the semicolon from the beginning of that line to make SSL working for gmail for localhost.

in php.ini file find [mail function] and change

SMTP=smtp.gmail.com
smtp_port=587
sendmail_from = [email protected]
sendmail_path = "C:\xampp\sendmail\sendmail.exe -t"

(use the above send mail path only and it will work)

Now Open C:\xampp\sendmail\sendmail.ini. Replace all the existing code in sendmail.ini with following code

[sendmail]

smtp_server=smtp.gmail.com
smtp_port=587
error_logfile=error.log
debug_logfile=debug.log
[email protected]
auth_password=my-gmail-password
[email protected]

Now you have done!! create php file with mail function and send mail from localhost.

Update

First, make sure you PHP installation has SSL support (look for an "openssl" section in the output from phpinfo()).

You can set the following settings in your PHP.ini:

ini_set("SMTP","ssl://smtp.gmail.com");
ini_set("smtp_port","465");

For regex, I first look at this web site: RegExLib.com

Try using SMTP to send email:-

$mail->IsSMTP();
$mail->Host = "smtp.example.com";

// optional
// used only when SMTP requires authentication  
$mail->SMTPAuth = true;
$mail->Username = 'smtp_username';
$mail->Password = 'smtp_password';

Perhaps your hosting server and email server are located at same place and you don't need to go for smtp authentication. Just keep every thing default like:

$config = array(        
    'protocol' => '',
    'smtp_host' => '',
    'smtp_port' => '',
    'smtp_user' => '[email protected]',
    'smtp_pass' => '**********'
    );

or

$config['protocol'] = '';
$config['smtp_host'] = '';
$config['smtp_port'] = ;
$config['smtp_user'] = '[email protected]';
$config['smtp_pass'] = 'password';

it works for me.

Well, the easiest solution would of course be to pipe the output into mail:

vs@lambda:~$ cat test.sh
sleep 3 && echo test | mail -s test your@address
vs@lambda:~$ nohup sh test.sh
nohup: ignoring input and appending output to `nohup.out'

I guess sh test.sh & will do just as fine normally.

You can add subject added to the mailto command using either one of the following ways. Add ?subject out mailto to the mailto tag.

<a href="mailto:[email protected]?subject=testing out mailto">First Example</a>

We can also add text into the body of the message by adding &body to the end of the tag as shown in the below example.

 <a href="mailto:[email protected]?subject=testing out mailto&body=Just testing">Second Example</a>

How to add subject to mailto tag

According to official standard RFC 2822 valid email regex is

(?:[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*|"(?:[\x01-\x08\x0b\x0c\x0e-\x1f\x21\x23-\x5b\x5d-\x7f]|\\[\x01-\x09\x0b\x0c\x0e-\x7f])*")@(?:(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?|\[(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.){3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?|[a-z0-9-]*[a-z0-9]:(?:[\x01-\x08\x0b\x0c\x0e-\x1f\x21-\x5a\x53-\x7f]|\\[\x01-\x09\x0b\x0c\x0e-\x7f])+)\])

if you want to use it in Java its really very easy

import java.util.regex.*;

class regexSample 
{
   public static void main(String args[]) 
   {
      //Input the string for validation
      String email = "[email protected]";

      //Set the email pattern string
      Pattern p = Pattern.compile(" (?:[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*|"
              +"(?:[\\x01-\\x08\\x0b\\x0c\\x0e-\\x1f\\x21\\x23-\\x5b\\x5d-\\x7f]|\\[\\x01-\\x09\\x0b\\x0c\\x0e-\\x7f])*\")"
                     + "@(?:(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?|\\[(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\\.){3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?|[a-z0-9-]*[a-z0-9]:(?:[\\x01-\\x08\\x0b\\x0c\\x0e-\\x1f\\x21-\\x5a\\x53-\\x7f]|\\[\\x01-\\x09\\x0b\\x0c\\x0e-\\x7f])+)\\]");

      //Match the given string with the pattern
      Matcher m = p.matcher(email);

      //check whether match is found 
      boolean matchFound = m.matches();

      if (matchFound)
        System.out.println("Valid Email Id.");
      else
        System.out.println("Invalid Email Id.");
   }
}

Support, unfortunately, is brutal at best. Here's a post on the topic:

https://www.campaignmonitor.com/blog/email-marketing/2013/02/embedded-images-in-html-email/

And the post content:

in php.ini file,uncomment this one

sendmail_path = "\"C:\xampp\sendmail\sendmail.exe\" -t"
;sendmail_path="C:\xampp\mailtodisk\mailtodisk.exe"

and in sendmail.ini

smtp_server=smtp.gmail.com
smtp_port=465
error_logfile=error.log
debug_logfile=debug.log
[email protected]
auth_password=yourpassword
[email protected]
hostname=localhost

configure this one..it will works...it working fine for me.

thanks.

320

And the segments look like this

{64}@{255}

64 + 1 + 255 = 320

You should also read this if you are validating emails

Use this method it under your email service it can attach any email body and attachments to Microsoft outlook

using Outlook = Microsoft.Office.Interop.Outlook; // Reference Microsoft.Office.Interop.Outlook from local or nuget if you will user a build agent later

 try {
                    var officeType = Type.GetTypeFromProgID("Outlook.Application");
    
                    if(officeType == null) {//outlook is not installed
                        return new PdfErrorResponse {
                            ErrorMessage = "System cant start Outlook!, make sure outlook is installed on your computer."
                        };
                    } else {
                        // Outlook is installed.    
                        // Continue your work.
                        Outlook.Application objApp = new Outlook.Application();
                        Outlook.MailItem mail = null;
                        mail = (Outlook.MailItem)objApp.CreateItem(Outlook.OlItemType.olMailItem);
                        //The CreateItem method returns an object which has to be typecast to MailItem 
                        //before using it.
                        mail.Attachments.Add(attachmentFilePath,Outlook.OlAttachmentType.olEmbeddeditem,1,$"Attachment{ordernumber}");
                        //The parameters are explained below
                        mail.To = recipientEmailAddress;
                        //mail.CC = "[email protected]";//All the mail lists have to be separated by the ';'
    
                        //To send email:
                        //mail.Send();
                        //To show email window
                        await Task.Run(() => mail.Display());
                    }
    
                } catch(System.Exception) {
                    return new PdfErrorResponse {
                        ErrorMessage = "System cant start Outlook!, make sure outlook is installed on your computer."
                    };
                }

Try to set the port on 26, this has fixed my problem with the message "data not accepted".

As per RFC2368 which defines mailto:, further reinforced by an example in RFC1738, it is explicitly stated that the only valid way to generate a line break is with %0D%0A.

This also applies to all url schemes such as gopher, smtp, sdp, imap, ldap, etc..

Or you can have extension for optional text of UITextField:

how to use:

if  emailTextField.text.isEmailValid() {
      print("email is valid")
}else{
      print("wrong email address")
}

extension:

extension Optional where Wrapped == String {
    func isEmailValid() -> Bool{
        guard let email = self else { return false }
        let emailPattern = "[A-Za-z-0-9.-_]+@[A-Za-z0-9]+\\.[A-Za-z]{2,3}"
        do{
            let regex = try NSRegularExpression(pattern: emailPattern, options: .caseInsensitive)
            let foundPatters = regex.numberOfMatches(in: email, options: .anchored, range: NSRange(location: 0, length: email.count))
            if foundPatters > 0 {
                return true
            }
        }catch{
            //error
        }
        return false
    }
}

If you can't follow Max's suggestion of installing Blat (or any other utility) on your server, then perhaps your server already has software installed that can send emails.

I know that both Oracle and SqlServer have the capability to send email. You might have to work with your DBA to get that feature enabled and/or get the privilege to use it. Of course I can see how that might present its own set of problems and red tape. Assuming you can access the feature, it is fairly simple to have a batch file login to a database and send mail.

A batch file can easily run a VBScript via CSCRIPT. A quick google search finds many links showing how to send email with VBScript. The first one I happened to look at was http://www.activexperts.com/activmonitor/windowsmanagement/adminscripts/enterprise/mail/. It looks straight forward.

Using ubuntu 10.4, this is how the mutt solution is written

echo | mutt -a myfile.zip -- [email protected]

Your email variable is empty because of the scope, you should set a use clause such as:

Mail::send('emails.activation', $data, function($message) use ($email, $subject) {
    $message->to($email)->subject($subject);
});

If not HTML, then UTF-8 is not recommended. koi8-r and windows-1251 only without problems. So use html mail.

$headers['Content-Type']='text/html; charset=UTF-8';
$body='<html><head><meta charset="UTF-8"><title>ESP Notufy - ESP ?????????</title></head><body>'.$text.'</body></html>';


$mail_object=& Mail::factory('smtp',
    array ('host' => $host,
        'auth' => true,
        'username' => $username,
        'password' => $password));
$mail_object->send($recipents, $headers, $body);
}

Unless you have a mail server set up on your local computer, setting SMTP = localhost won't have any effect.

In days gone by (long ago), it was sufficient to set the value of SMTP to the address of your ISP's SMTP server. This now rarely works because most ISPs insist on authentication with a username and password. However, the PHP mail() function doesn't support SMTP authentication. It's designed to work directly with the mail transport agent of the local server.

You either need to set up a local mail server or to use a PHP classs that supports SMTP authentication, such as Zend_Mail or PHPMailer. The simplest solution, however, is to upload your mail processing script to your remote server.

I guess problem is in width attributes in table and td remove 'px' for example

<table border="0" cellpadding="0" cellspacing="0" width="580px" style="background-color: #0290ba;">

Should be

<table border="0" cellpadding="0" cellspacing="0" width="580" style="background-color: #0290ba;">

Anybody can try the following (mailto function only accepts plaintext but here i show how to use HTML innertext properties and how to add an anchor as mailto body params):

//Create as many html elements you need.

const titleElement = document.createElement("DIV");
titleElement.innerHTML = this.shareInformation.title; // Just some string

//Here I create an <a> so I can use href property
const titleLinkElement = document.createElement("a");
titleLinkElement.href = this.shareInformation.link; // This is a url

...

let mail = document.createElement("a");

// Using es6 template literals add the html innerText property and anchor element created to mailto body parameter
mail.href = 
  `mailto:?subject=${titleElement.innerText}&body=${titleLinkElement}%0D%0A${abstractElement.innerText}`;
mail.click();

// Notice how I use ${titleLinkElement} that is an anchor element, so mailto uses its href and renders the url I needed

I am storing a class object into a string using toString() method. Now, I want to convert the string into that class object.

First, if I'm understanding your question, you want to store your object into a String and then later to be able to read it again and re-create the Object.

Personally, when I need to do that I use ObjectOutputStream. However, there is a mandatory condition. The object you want to convert to a String and then back to an Object must be a Serializable object, and also all its attributes.

Let's Consider ReadWriteObject, the object to manipulate and ReadWriteTest the manipulator.

Here is how I would do it:

public class ReadWriteObject implements Serializable {

    /** Serial Version UID */
    private static final long serialVersionUID = 8008750006656191706L;

    private int age;
    private String firstName;
    private String lastName;

    /**
     * @param age
     * @param firstName
     * @param lastName
     */
    public ReadWriteObject(int age, String firstName, String lastName) {
        super();
        this.age = age;
        this.firstName = firstName;
        this.lastName = lastName;
    }

    /*
     * (non-Javadoc)
     * 
     * @see java.lang.Object#toString()
     */
    @Override
    public String toString() {
        return "ReadWriteObject [age=" + age + ", firstName=" + firstName + ", lastName=" + lastName + "]";
    }

}


public class ReadWriteTest {

    public static void main(String[] args) throws IOException, ClassNotFoundException {
        // Create Object to write and then to read
        // This object must be Serializable, and all its subobjects as well
        ReadWriteObject inputObject = new ReadWriteObject(18, "John", "Doe");

        // Read Write Object test

        // Write Object into a Byte Array
        ByteArrayOutputStream baos = new ByteArrayOutputStream(1024);
        ObjectOutputStream oos = new ObjectOutputStream(baos);
        oos.writeObject(inputObject);
        byte[] rawData = baos.toByteArray();
        String rawString = new String(rawData);
        System.out.println(rawString);

        // Read Object from the Byte Array
        byte[] byteArrayFromString = rawString.getBytes();
        ByteArrayInputStream bais = new ByteArrayInputStream(byteArrayFromString);
        ObjectInputStream ois = new ObjectInputStream(bais);
        Object outputObject = ois.readObject();
        System.out.println(outputObject);
    }
}

The Standard Output is similar to that (actually, I can't copy/paste it) :

¬í ?sr ?*com.ajoumady.stackoverflow.ReadWriteObjecto$˲é¦LÚ ?I ?ageL ?firstNamet ?Ljava/lang/String;L ?lastNameq ~ ?xp ?t ?John ?Doe

ReadWriteObject [age=18, firstName=John, lastName=Doe]

Try This(Simple javascript):-

 <!DOCTYPE html>_x000D_
    <html>_x000D_
       <script>_x000D_
          function change(value){_x000D_
          document.getElementById("count").value= 500*value;_x000D_
          document.getElementById("totalValue").innerHTML= "Total price: $" + 500*value;_x000D_
          }_x000D_
          _x000D_
       </script>_x000D_
       <body>_x000D_
          Product price: $500_x000D_
          <br>_x000D_
          <div id= "totalValue">Total price: $500 </div>_x000D_
          <br>_x000D_
          <input type="button" onclick="change(2)" value="2&#x00A;Qty">_x000D_
          <input type="button" onclick="change(4)" value="4&#x00A;Qty">_x000D_
          <br>_x000D_
          Total <input type="text" id="count" value="1">_x000D_
       </body>_x000D_
    </html>

Hope this will help you..

For posterity: as of 0.15.0, there is a handy .dt accessor you can use to pull such values from a datetime/period series (in the above case, just sales.timestamp.dt.hour!

I also had similar problems when trying to link static compiled fontconfig and expat into a linux shared object:

/opt/rh/devtoolset-7/root/usr/libexec/gcc/x86_64-redhat-linux/7/ld: /3rdparty/fontconfig/lib/linux-x86_64/libfontconfig.a(fccfg.o): relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a shared object; recompile with -fPIC
/opt/rh/devtoolset-7/root/usr/libexec/gcc/x86_64-redhat-linux/7/ld: /3rdparty/expat/lib/linux-x86_64/libexpat.a(xmlparse.o): relocation R_X86_64_PC32 against symbol `stderr@@GLIBC_2.2.5' can not be used when making a shared object; recompile with -fPIC
[...]

This contrary to the fact that I was already passing -fPIC flags though CFLAGS variable, and other compilers/linkers variants (clang/lld) were perfectly working with the same build configuration. It ended up that these dependencies control position-independent code settings through despicable autoconf scripts and need --with-pic switch during build configuration on linux gcc/ld combination, and its lack probably overrides same the setting in CFLAGS. Pass the switch to configure script and the dependencies will be correctly compiled with -fPIC.

I'm not sure you understand what "exit" states

Terminates execution of the script. Shutdown functions and object destructors will always be executed even if exit is called.

It's normal to do that, it must clear it's memmory of all the variables and functions you called before. Not doing this would mean your memmory would remain stuck and ocuppied in your RAM, and if this would happen several times you would need to reboot and flush your RAM in order to have any left.

SELECT DATEPART(QUARTER, @date)

This returns the quarter of the @date, assuming @date is a DATETIME.

I tried everything and nothing worked so here is another solution that finally worked (for me).

I had to check Enable Java EE configuration under Preferences -> Maven -> Jave EE configuration

After that you can check that more entries were added in Deployment assemblies of the project settings.

You will find create_tables.sql.gz file in /usr/share/doc/phpmyadmin/examples/ dir

Extract it and change pma_ prefix by pma__ or vice versa

Then import you new script SQL :

As Chris suggests, you can do it like this:

public string GetXMLAsString(XmlDocument myxml)
{
    return myxml.OuterXml;
}

Or like this:

public string GetXMLAsString(XmlDocument myxml)
    {

        StringWriter sw = new StringWriter();
        XmlTextWriter tx = new XmlTextWriter(sw);
        myxml.WriteTo(tx);

        string str = sw.ToString();// 
        return str;
    }

and if you really want to create a new XmlDocument then do this

XmlDocument newxmlDoc= myxml

Using async and await it is lot more easy.

router.post('/login',async (req, res, next) => {
i = await queries.checkUser(req.body);
console.log('i: '+JSON.stringify(i));
});

//User Available Check
async function checkUser(request) {
try {
    let response = await sql.query('select * from login where email = ?', 
    [request.email]);
    return response[0];

    } catch (err) {
    console.log(err);

  }

}

reload the form

Form1_Load(sender, e)

Just add parameters, split by comma:

UPDATE tablename SET column1 = "value1", column2 = "value2" ....

See also: mySQL manual on UPDATE

In Java, you can't, as foreach was meant to hide the iterator. You must do the normal For loop in order to get the current iteration.

x and y returns true if both x and y are true.
x or y returns if either one is true.

From this we can conclude that or contains and within itself unless you mean xOR (or except if and is true)

Stefan Haustein function for xamarin/c#:

public string GetFilenameFromURI(Android.Net.Uri uri)
        {
            string result = null;
            if (uri.Scheme == "content")
            {
                using (var cursor = Application.Context.ContentResolver.Query(uri, null, null, null, null))
                {
                    try
                    {
                        if (cursor != null && cursor.MoveToFirst())
                        {
                            result = cursor.GetString(cursor.GetColumnIndex(OpenableColumns.DisplayName));
                        }
                    }
                    finally
                    {
                        cursor.Close();
                    }
                }
            }
            if (result == null)
            {
                result = uri.Path;
                int cut = result.LastIndexOf('/');
                if (cut != -1)
                {
                    result = result.Substring(cut + 1);
                }
            }
            return result;
        }

These are behavior patterns I have noticed while trying to understand Jackson serialization.

1) Assume there is an object Classroom and a class Student. I've made everything public and final for ease.

public class Classroom {
    public final double double1 = 1234.5678;
    public final Double Double1 = 91011.1213;
    public final Student student1 = new Student();
}

public class Student {
    public final double double2 = 1920.2122;
    public final Double Double2 = 2324.2526;
}

2) Assume that these are the serializers we use for serializing the objects into JSON. The writeObjectField uses the object's own serializer if it is registered with the object mapper; if not, then it serializes it as a POJO. The writeNumberField exclusively only accepts primitives as arguments.

public class ClassroomSerializer extends StdSerializer<Classroom> {
    public ClassroomSerializer(Class<Classroom> t) {
        super(t);
    }

    @Override
    public void serialize(Classroom value, JsonGenerator jgen, SerializerProvider provider) throws IOException, JsonGenerationException {
        jgen.writeStartObject();
        jgen.writeObjectField("double1-Object", value.double1);
        jgen.writeNumberField("double1-Number", value.double1);
        jgen.writeObjectField("Double1-Object", value.Double1);
        jgen.writeNumberField("Double1-Number", value.Double1);
        jgen.writeObjectField("student1", value.student1);
        jgen.writeEndObject();
    }
}

public class StudentSerializer extends StdSerializer<Student> {
    public StudentSerializer(Class<Student> t) {
        super(t);
    }

    @Override
    public void serialize(Student value, JsonGenerator jgen, SerializerProvider provider) throws IOException, JsonGenerationException {
        jgen.writeStartObject();
        jgen.writeObjectField("double2-Object", value.double2);
        jgen.writeNumberField("double2-Number", value.double2);
        jgen.writeObjectField("Double2-Object", value.Double2);
        jgen.writeNumberField("Double2-Number", value.Double2);
        jgen.writeEndObject();
    }
}

3) Register only a DoubleSerializer with DecimalFormat output pattern ###,##0.000, in SimpleModule and the output is:

{
  "double1" : 1234.5678,
  "Double1" : {
    "value" : "91,011.121"
  },
  "student1" : {
    "double2" : 1920.2122,
    "Double2" : {
      "value" : "2,324.253"
    }
  }
}

You can see that the POJO serialization differentiates between double and Double, using the DoubleSerialzer for Doubles and using a regular String format for doubles.

4) Register DoubleSerializer and ClassroomSerializer, without the StudentSerializer. We expect that the output is such that if we write a double as an object, it behaves like a Double, and if we write a Double as a number, it behaves like a double. The Student instance variable should be written as a POJO and follow the pattern above since it does not register.

{
  "double1-Object" : {
    "value" : "1,234.568"
  },
  "double1-Number" : 1234.5678,
  "Double1-Object" : {
    "value" : "91,011.121"
  },
  "Double1-Number" : 91011.1213,
  "student1" : {
    "double2" : 1920.2122,
    "Double2" : {
      "value" : "2,324.253"
    }
  }
}

5) Register all serializers. The output is:

{
  "double1-Object" : {
    "value" : "1,234.568"
  },
  "double1-Number" : 1234.5678,
  "Double1-Object" : {
    "value" : "91,011.121"
  },
  "Double1-Number" : 91011.1213,
  "student1" : {
    "double2-Object" : {
      "value" : "1,920.212"
    },
    "double2-Number" : 1920.2122,
    "Double2-Object" : {
      "value" : "2,324.253"
    },
    "Double2-Number" : 2324.2526
  }
}

exactly as expected.

Another important note: If you have multiple serializers for the same class registered with the same Module, then the Module will select the serializer for that class that is most recently added to the list. This should not be used - it's confusing and I am not sure how consistent this is

Moral: if you want to customize serialization of primitives in your object, you must write your own serializer for the object. You cannot rely on the POJO Jackson serialization.

A little background information:

As said, if you want to have a dynamic collection of things, use a List<T>. Internally, a List uses an array for storage too. That array has a fixed size just like any other array. Once an array is declared as having a size, it doesn't change. When you add an item to a List, it's added to the array. Initially, the List starts out with an array that I believe has a length of 16. When you try to add the 17th item to the List, what happens is that a new array is allocated, that's (I think) twice the size of the old one, so 32 items. Then the content of the old array is copied into the new array. So while a List may appear dynamic to the outside observer, internally it has to comply to the rules as well.

And as you might have guessed, the copying and allocation of the arrays isn't free so one should aim to have as few of those as possible and to do that you can specify (in the constructor of List) an initial size of the array, which in a perfect scenario is just big enough to hold everything you want. However, this is micro-optimization and it's unlikely it will ever matter to you, but it's always nice to know what you're actually doing.

you have done it the correct way using

curl_setopt($ch, CURLOPT_POSTFIELDS,$body);

but i notice your missing

curl_setopt($ch, CURLOPT_POST,1);

You can not create URI from resources inside of the jar file. You can simply write it to the temp file and then use it (java8):

Path path = File.createTempFile("some", "address").toPath();
Files.copy(ClassLoader.getSystemResourceAsStream("/path/to/resource"), path, StandardCopyOption.REPLACE_EXISTING);

Eric Saupe knows how to do it

$('a[data-toggle="tab"]').on('shown.bs.tab', function (e) {_x000D_
  var target = $(e.target).attr("href") // activated tab_x000D_
  alert(target);_x000D_
});

I needed to do this just now and required a cross-platform solution that was suitable for c++11, boost and openssl. I took D'Nabre's solution as a starting point and boiled it down to the following:

#include <openssl/md5.h>
#include <iomanip>
#include <sstream>
#include <boost/iostreams/device/mapped_file.hpp>

const std::string md5_from_file(const std::string& path)
{
    unsigned char result[MD5_DIGEST_LENGTH];
    boost::iostreams::mapped_file_source src(path);
    MD5((unsigned char*)src.data(), src.size(), result);

    std::ostringstream sout;
    sout<<std::hex<<std::setfill('0');
    for(auto c: result) sout<<std::setw(2)<<(int)c;

    return sout.str();
}

A quick test executable demonstrates:

#include <iostream>

int main(int argc, char *argv[]) {
    if(argc != 2) {
        std::cerr<<"Must specify the file\n";
        exit(-1);
    }
    std::cout<<md5_from_file(argv[1])<<"  "<<argv[1]<<std::endl;
    return 0;
}

Some linking notes: Linux: -lcrypto -lboost_iostreams Windows: -DBOOST_ALL_DYN_LINK libeay32.lib ssleay32.lib

In static class, if you are getting information from xml or reg, class tries to initialize all properties. therefore, you should control if the config variable is there otherwise properties will not initialize so the class.

Check xml referance variable is there, Check reg referance variable is is there, Make sure you handle if they are not there.

Yes -- parseFloat.

parseFloat(document.getElementById(amtid4).innerHTML);

For formatting numbers, use toFixed:

var num = parseFloat(document.getElementById(amtid4).innerHTML).toFixed(2);

num is now a string with the number formatted with two decimal places.

Though many have already answered the difference between Val and var. But one point to notice is that val is not exactly like final keyword.

We can change the value of val using recursion but we can never change value of final. Final is more constant than Val.

def factorial(num: Int): Int = {
 if(num == 0) 1
 else factorial(num - 1) * num
}

Method parameters are by default val and at every call value is being changed.

    var topbarHeight: CGFloat {

    }
}

For the guys who still search some cool and easy spinner, we have multiple exemples of spinner on fontawesome site : https://fontawesome.com/v4.7.0/examples/

You just have to inspect the spinner you want with your debugger and copy the css styles.

Thought to add my solution for this, after spending a few hours on the same error :(

The guys above were correct that the first thing you should check is whether you had missed adding any frameworks, see the steps provided by Pruthvid above.

My problem, it turned out, was a compile class missing after I deleted it, and later added it back in again.

Check your "Compile Sources" as shown for the reported error classes. Add in any missing classes that you created.

NOTE: This error is almost always caused because the command does not exist, because the working directory does not exist, or from a windows-only bug.

I found a particular easy way to get the idea of the root cause of:

Error: spawn ENOENT

The problem of this error is, there is really little information in the error message to tell you where the call site is, i.e. which executable/command is not found, especially when you have a large code base where there are a lot of spawn calls. On the other hand, if we know the exact command that cause the error then we can follow @laconbass' answer to fix the problem.

I found a very easy way to spot which command cause the problem rather than adding event listeners everywhere in your code as suggested in @laconbass' answer. The key idea is to wrap the original spawn call with a wrapper which prints the arguments send to the spawn call.

Here is the wrapper function, put it at the top of the index.js or whatever your server's starting script.

(function() {
    var childProcess = require("child_process");
    var oldSpawn = childProcess.spawn;
    function mySpawn() {
        console.log('spawn called');
        console.log(arguments);
        var result = oldSpawn.apply(this, arguments);
        return result;
    }
    childProcess.spawn = mySpawn;
})();

Then the next time you run your application, before the uncaught exception's message you will see something like that:

spawn called
{ '0': 'hg',
  '1': [],
  '2':
   { cwd: '/* omitted */',
     env: { IP: '0.0.0.0' },
     args: [] } }

In this way you can easily know which command actually is executed and then you can find out why nodejs cannot find the executable to fix the problem.

A foreach loop calls the GetEnumerator method.
If the collection is null, this method call results in a NullReferenceException.

It is bad practice to return a null collection; your methods should return an empty collection instead.

For Python 3.2+ simple-date is a wrapper around pytz that tries to simplify things.

If you have a time then

SimpleDate(time).convert(tz="...")

may do what you want. But timezones are quite complex things, so it can get significantly more complicated - see the the docs.

./gradlew

Your directory with gradlew is not included in the PATH, so you must specify path to the gradlew. . means "current directory".

The common way is the format() function:

>>> s = "This is an {example} with {vars}".format(vars="variables", example="example")
>>> s
'This is an example with variables'

It works fine with a multi-line format string:

>>> s = '''\
... This is a {length} example.
... Here is a {ordinal} line.\
... '''.format(length='multi-line', ordinal='second')
>>> print(s)
This is a multi-line example.
Here is a second line.

You can also pass a dictionary with variables:

>>> d = { 'vars': "variables", 'example': "example" }
>>> s = "This is an {example} with {vars}"
>>> s.format(**d)
'This is an example with variables'

The closest thing to what you asked (in terms of syntax) are template strings. For example:

>>> from string import Template
>>> t = Template("This is an $example with $vars")
>>> t.substitute({ 'example': "example", 'vars': "variables"})
'This is an example with variables'

I should add though that the format() function is more common because it's readily available and it does not require an import line.

//ul[@class="featureList" and li//text()[contains(., "Model")]]

int[] anArray = { 1, 5, 2, 7 };
// Finding max
int m = anArray.Max();

// Positioning max
int p = Array.IndexOf(anArray, m);

If the move-left and move-right shortcuts do not appear on your screen, click at the rightmost position of your toolbar at the top. You should get "Add or Remove Buttons." Add the buttons "decrease line indent" and "increase line indent"

To get body lines use escape()

body_line =  escape("\n");

so

href = "mailto:[email protected]?body=hello,"+body_line+"I like this.";

This new package looks nice http://cran.r-project.org/web/packages/openxlsx/openxlsx.pdf It doesn't require rJava and is using 'Rcpp' for speed.

To disable foreign key constraints:

DECLARE @sql NVARCHAR(MAX) = N'';

;WITH x AS 
(
  SELECT DISTINCT obj = 
      QUOTENAME(OBJECT_SCHEMA_NAME(parent_object_id)) + '.' 
    + QUOTENAME(OBJECT_NAME(parent_object_id)) 
  FROM sys.foreign_keys
)
SELECT @sql += N'ALTER TABLE ' + obj + ' NOCHECK CONSTRAINT ALL;
' FROM x;

EXEC sp_executesql @sql;

To re-enable:

DECLARE @sql NVARCHAR(MAX) = N'';

;WITH x AS 
(
  SELECT DISTINCT obj = 
      QUOTENAME(OBJECT_SCHEMA_NAME(parent_object_id)) + '.' 
    + QUOTENAME(OBJECT_NAME(parent_object_id)) 
  FROM sys.foreign_keys
)
SELECT @sql += N'ALTER TABLE ' + obj + ' WITH CHECK CHECK CONSTRAINT ALL;
' FROM x;

EXEC sp_executesql @sql;

However, you will not be able to truncate the tables, you will have to delete from them in the right order. If you need to truncate them, you need to drop the constraints entirely, and re-create them. This is simple to do if your foreign key constraints are all simple, single-column constraints, but definitely more complex if there are multiple columns involved.

Here is something you can try. In order to make this a part of your SSIS package you'll need a place to store the FK definitions while the SSIS package runs (you won't be able to do this all in one script). So in some utility database, create a table:

CREATE TABLE dbo.PostCommand(cmd NVARCHAR(MAX));

Then in your database, you can have a stored procedure that does this:

DELETE other_database.dbo.PostCommand;

DECLARE @sql NVARCHAR(MAX) = N'';

SELECT @sql += N'ALTER TABLE ' + QUOTENAME(OBJECT_SCHEMA_NAME(fk.parent_object_id))
   + '.' + QUOTENAME(OBJECT_NAME(fk.parent_object_id)) 
   + ' ADD CONSTRAINT ' + fk.name + ' FOREIGN KEY (' 
   + STUFF((SELECT ',' + c.name
    FROM sys.columns AS c 
        INNER JOIN sys.foreign_key_columns AS fkc 
        ON fkc.parent_column_id = c.column_id
        AND fkc.parent_object_id = c.[object_id]
    WHERE fkc.constraint_object_id = fk.[object_id]
    ORDER BY fkc.constraint_column_id 
    FOR XML PATH(''), TYPE).value('.', 'nvarchar(max)'), 1, 1, '')
+ ') REFERENCES ' + 
QUOTENAME(OBJECT_SCHEMA_NAME(fk.referenced_object_id))
+ '.' + QUOTENAME(OBJECT_NAME(fk.referenced_object_id))
+ '(' + 
STUFF((SELECT ',' + c.name
    FROM sys.columns AS c 
        INNER JOIN sys.foreign_key_columns AS fkc 
        ON fkc.referenced_column_id = c.column_id
        AND fkc.referenced_object_id = c.[object_id]
    WHERE fkc.constraint_object_id = fk.[object_id]
    ORDER BY fkc.constraint_column_id 
    FOR XML PATH(''), TYPE).value('.', 'nvarchar(max)'), 1, 1, '') + ');
' FROM sys.foreign_keys AS fk
WHERE OBJECTPROPERTY(parent_object_id, 'IsMsShipped') = 0;

INSERT other_database.dbo.PostCommand(cmd) SELECT @sql;

IF @@ROWCOUNT = 1
BEGIN
  SET @sql = N'';

  SELECT @sql += N'ALTER TABLE ' + QUOTENAME(OBJECT_SCHEMA_NAME(fk.parent_object_id))
    + '.' + QUOTENAME(OBJECT_NAME(fk.parent_object_id)) 
    + ' DROP CONSTRAINT ' + fk.name + ';
  ' FROM sys.foreign_keys AS fk;

  EXEC sp_executesql @sql;
END

Now when your SSIS package is finished, it should call a different stored procedure, which does:

DECLARE @sql NVARCHAR(MAX);

SELECT @sql = cmd FROM other_database.dbo.PostCommand;

EXEC sp_executesql @sql;

If you're doing all of this just for the sake of being able to truncate instead of delete, I suggest just taking the hit and running a delete. Maybe use bulk-logged recovery model to minimize the impact of the log. In general I don't see how this solution will be all that much faster than just using a delete in the right order.

In 2014 I published a more elaborate post about this here:

• Drop and Re-Create All Foreign Key Constraints in SQL Server

Here what you can try:

var d = Date.parse("2016-07-19T20:23:01.804Z");
alert(d); //this is in milliseconds

Locks still have uses in JS. In my experience I only needed to use locks to prevent spam clicking on elements making AJAX calls. If you have a loader set up for AJAX calls then this isn't required (as well as disabling the button after clicking). But either way here is what I used for locking:

var LOCK_INDEX = [];
function LockCallback(key, action, manual) {
    if (LOCK_INDEX[key])
        return;
    LOCK_INDEX[key] = true;
    action(function () { delete LOCK_INDEX[key] });
    if (!manual)
        delete LOCK_INDEX[key];
}

Usage:

Manual unlock (usually for XHR)

LockCallback('someKey',(delCallback) => { 
    //do stuff
    delCallback(); //Unlock method
}, true)

Auto unlock

LockCallback('someKey',() => { 
    //do stuff
})

If your table is MyISAM:

SELECT  *
FROM    pages
WHERE   MATCH(title, content) AGAINST ('keyword' IN BOOLEAN MODE)

This will be much faster if you create a FULLTEXT index on your columns:

CREATE FULLTEXT INDEX fx_pages_title_content ON pages (title, content)

, but will work even without the index.

I know it's an old question but maybe someone can use this solution:

int size = 0; // Fill all bits with zero (0)
size = ~size; // Negate all bits, thus all bits are set to one (1)

So far we have -1 as result 'till size is a signed int.

size = (unsigned int)size >> 1; // Shift the bits of size one position to the right.

As Standard says, bits that are shifted in are 1 if variable is signed and negative and 0 if variable would be unsigned or signed and positive.

As size is signed and negative we would shift in sign bit which is 1, which is not helping much, so we cast to unsigned int, forcing to shift in 0 instead, setting the sign bit to 0 while letting all other bits remain 1.

cout << size << endl; // Prints out size which is now set to maximum positive value.

We could also use a mask and xor but then we had to know the exact bitsize of the variable. With shifting in bits front, we don't have to know at any time how many bits the int has on machine or compiler nor need we include extra libraries.

It is the same as the HTML or JavaScript block comments:

<!-- The to-be-commented XML block goes here. -->

This work for me!

$(document).ready(function() {
    $(document).on("click", "#tableId tbody tr", function() {
        //some think
    });
});

git for-each-ref --format='%(refname:short) <- %(upstream:short)' refs/heads

will show a line for each local branch. A tracking branch will look like:

master <- origin/master

A non-tracking one will look like:

test <- 

TL;DR: rails g scaffold_controller <name>

Even though you already have a model, you can still generate the necessary controller and migration files by using the rails generate option. If you run rails generate -h you can see all of the options available to you.

Rails:
  controller
  generator
  helper
  integration_test
  mailer
  migration
  model
  observer
  performance_test
  plugin
  resource
  scaffold
  scaffold_controller
  session_migration
  stylesheets

If you'd like to generate a controller scaffold for your model, see scaffold_controller. Just for clarity, here's the description on that:

Stubs out a scaffolded controller and its views. Pass the model name, either CamelCased or under_scored, and a list of views as arguments. The controller name is retrieved as a pluralized version of the model name.

To create a controller within a module, specify the model name as a path like 'parent_module/controller_name'.

This generates a controller class in app/controllers and invokes helper, template engine and test framework generators.

To create your resource, you'd use the resource generator, and to create a migration, you can also see the migration generator (see, there's a pattern to all of this madness). These provide options to create the missing files to build a resource. Alternatively you can just run rails generate scaffold with the --skip option to skip any files which exist :)

I recommend spending some time looking at the options inside of the generators. They're something I don't feel are documented extremely well in books and such, but they're very handy.

Another tree implementation loosely based off of Bruno's answer:

class Node:
    def __init__(self):
        self.name: str = ''
        self.children: List[Node] = []
        self.parent: Node = self

    def __getitem__(self, i: int) -> 'Node':
        return self.children[i]

    def add_child(self):
        child = Node()
        self.children.append(child)
        child.parent = self
        return child

    def __str__(self) -> str:
        def _get_character(x, left, right) -> str:
            if x < left:
                return '/'
            elif x >= right:
                return '\\'
            else:
                return '|'

        if len(self.children):
            children_lines: Sequence[List[str]] = list(map(lambda child: str(child).split('\n'), self.children))
            widths: Sequence[int] = list(map(lambda child_lines: len(child_lines[0]), children_lines))
            max_height: int = max(map(len, children_lines))
            total_width: int = sum(widths) + len(widths) - 1
            left: int = (total_width - len(self.name) + 1) // 2
            right: int = left + len(self.name)

            return '\n'.join((
                self.name.center(total_width),
                ' '.join(map(lambda width, position: _get_character(position - width // 2, left, right).center(width),
                             widths, accumulate(widths, add))),
                *map(
                    lambda row: ' '.join(map(
                        lambda child_lines: child_lines[row] if row < len(child_lines) else ' ' * len(child_lines[0]),
                        children_lines)),
                    range(max_height))))
        else:
            return self.name

And an example of how to use it:

tree = Node()
tree.name = 'Root node'
tree.add_child()
tree[0].name = 'Child node 0'
tree.add_child()
tree[1].name = 'Child node 1'
tree.add_child()
tree[2].name = 'Child node 2'
tree[1].add_child()
tree[1][0].name = 'Grandchild 1.0'
tree[2].add_child()
tree[2][0].name = 'Grandchild 2.0'
tree[2].add_child()
tree[2][1].name = 'Grandchild 2.1'
print(tree)

Which should output:

                        Root node                        
     /             /                      \              
Child node 0  Child node 1           Child node 2        
                   |              /              \       
             Grandchild 1.0 Grandchild 2.0 Grandchild 2.1

To sort in descending order you can flip the two parameters

int[][] array= {
    {1, 5},
    {13, 1},
    {12, 100},
    {12, 85} 
};
Arrays.sort(array, (b, a) -> Integer.compare(a[0], b[0]));

Output:

13, 5
12, 100
12, 85
1, 5

You can do this without JavaScript. You can set the style on both divs to position: fixed and overflow-y: auto. You may need to make one of them higher than the other by setting its z-index (if they overlap).

Here's a basic example on CodePen.

If you're using the git GUI (on Windows) under the Repository menu you can use "Visualize master's History". Highlight a commit in the top pane and a file in the lower right and you'll see the diff for that commit in the lower left.

If the files are already in version control you need to remove them manually.

So for people who want semantics similar to:

$ chmod 755 somefile

Use:

$ python -c "import os; os.chmod('somefile', 0o755)"

If your Python is older than 2.6:

$ python -c "import os; os.chmod('somefile', 0755)"

Alternatively, you can use pseudo-elements to do so :) the advantage of the pseudo-element solution is that you can use it to space the inner border at an arbitrary distance away from the actual border, and the background will show through that space. The markup:

body {_x000D_
  background-image: linear-gradient(180deg, #ccc 50%, #fff 50%);_x000D_
  background-repeat: no-repeat;_x000D_
  height: 100vh;_x000D_
}_x000D_
.double-border {_x000D_
  background-color: #ccc;_x000D_
  border: 4px solid #fff;_x000D_
  padding: 2em;_x000D_
  width: 16em;_x000D_
  height: 16em;_x000D_
  position: relative;_x000D_
  margin: 0 auto;_x000D_
}_x000D_
.double-border:before {_x000D_
  background: none;_x000D_
  border: 4px solid #fff;_x000D_
  content: "";_x000D_
  display: block;_x000D_
  position: absolute;_x000D_
  top: 4px;_x000D_
  left: 4px;_x000D_
  right: 4px;_x000D_
  bottom: 4px;_x000D_
  pointer-events: none;_x000D_
}

<div class="double-border">_x000D_
  <!-- Content -->_x000D_
</div>

If you want borders that are consecutive to each other (no space between them), you can use multiple box-shadow declarations (separated by commas) to do so:

body {_x000D_
  background-image: linear-gradient(180deg, #ccc 50%, #fff 50%);_x000D_
  background-repeat: no-repeat;_x000D_
  height: 100vh;_x000D_

Switch to some other branch and delete Test_Branch, as follows:

$ git checkout master
$ git branch -d Test_Branch

If above command gives you error - The branch 'Test_Branch' is not fully merged. If you are sure you want to delete it and still you want to delete it, then you can force delete it using -D instead of -d, as:

$ git branch -D Test_Branch

To delete Test_Branch from remote as well, execute:

git push origin --delete Test_Branch

If the project has been already deleted from the project navigator, then right click in project navigator, and select refresh to refresh the workspace. Then re-add the deleted project.

This query comes from two other answers:

Get size of all tables in database

How to find largest objects in a SQL Server database?

, but I enhanced this to be universal. It uses sys.objects dictionary:

SELECT 
    s.NAME as SCHEMA_NAME,
    t.NAME AS OBJ_NAME,
    t.type_desc as OBJ_TYPE,
    i.name as indexName,
    sum(p.rows) as RowCounts,
    sum(a.total_pages) as TotalPages, 
    sum(a.used_pages) as UsedPages, 
    sum(a.data_pages) as DataPages,
    (sum(a.total_pages) * 8) / 1024 as TotalSpaceMB, 
    (sum(a.used_pages) * 8) / 1024 as UsedSpaceMB, 
    (sum(a.data_pages) * 8) / 1024 as DataSpaceMB
FROM 
    sys.objects t
INNER JOIN
    sys.schemas s ON t.SCHEMA_ID = s.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%' AND
    i.OBJECT_ID > 255 AND   
    i.index_id <= 1
GROUP BY 
    s.NAME, t.NAME, t.type_desc, i.object_id, i.index_id, i.name 
ORDER BY
    sum(a.total_pages) DESC
;

You can use something like ini_set('session.gc_maxlifetime', 28800); // 8 * 60 * 60 too.

As a conceptual example for understanding when you ought to use yield, let's say the method ConsumeLoop() processes the items returned/yielded by ProduceList():

void ConsumeLoop() {
    foreach (Consumable item in ProduceList())        // might have to wait here
        item.Consume();
}

IEnumerable<Consumable> ProduceList() {
    while (KeepProducing())
        yield return ProduceExpensiveConsumable();    // expensive
}

Without yield, the call to ProduceList() might take a long time because you have to complete the list before returning:

//pseudo-assembly
Produce consumable[0]                   // expensive operation, e.g. disk I/O
Produce consumable[1]                   // waiting...
Produce consumable[2]                   // waiting...
Produce consumable[3]                   // completed the consumable list
Consume consumable[0]                   // start consuming
Consume consumable[1]
Consume consumable[2]
Consume consumable[3]

Using yield, it becomes rearranged, sort of interleaved:

//pseudo-assembly
Produce consumable[0]
Consume consumable[0]                   // immediately yield & Consume
Produce consumable[1]                   // ConsumeLoop iterates, requesting next item
Consume consumable[1]                   // consume next
Produce consumable[2]
Consume consumable[2]                   // consume next
Produce consumable[3]
Consume consumable[3]                   // consume next

And lastly, as many before have already suggested, you should use Version 2 because you already have the completed list anyway.

If you want a no-bullet list (or any other non-standard usage) or more lines in a cell use <br />

For those interested in the OS X solution for apps like Intelli-J where authorizations are stored by OSX:

1. Hit CMD+SPACE
2. Type "keychain"
3. Open keychain access
4. Under "Keychains" on the left, choose "login"
5. Under "Category" on the right, choose "All items"
6. At the top right in the search box, type in the the host URL (e.g. svn.mycompany.com)
7. Your keychain item will show if you chose to have your Mac remember your login credentials.
8. Double click the item and check the "Show password" checkbox at the bottom of the dialog that pops up. You will have to enter your Mac login to reveal the password.

Much easier than having to try to decrypt a password :-)

If you really just want a random value from the available key range, use random.choice on the dictionary's values (converted to list form, if Python 3).

>>> from random import choice
>>> d = {1: 'a', 2: 'b', 3: 'c'}
>>>> choice(list(d.values()))

I think your issue is that Range("H18") doesn't contain a formula. Also, you could make your code more efficient by eliminating x. Instead, change your code to

Range("H18").GoalSeek Goal:=Range("H32").Value, ChangingCell:=Range("G18")

One more related question, since it took me forever to find the answer:

How to make the legend background blank (i.e. transparent, not white):

legend = plt.legend()
legend.get_frame().set_facecolor('none')

Warning, you want 'none' (the string). None means the default color instead.

It depends on what type of fading you are looking for.

But with shadow and rounded corners you can get a nice result. Rounded corners because the bigger the shadow, the weirder it will look in the edges unless you balance it out with rounded corners.

Python 3

from urllib.error import HTTPError

Python 2

from urllib2 import HTTPError

Just catch HTTPError, handle it, and if it's not Error 404, simply use raise to re-raise the exception.

See the Python tutorial.

e.g. complete example for Pyhton 2

import urllib2
from urllib2 import HTTPError
try:
   urllib2.urlopen("some url")
except HTTPError as err:
   if err.code == 404:
       <whatever>
   else:
       raise

I have just installed Python 3.6.2.

I got the path as

the reason of the exception has been explained already, however the suggested solution isn't really the best.

You should create a class that keeps a Scanner as private using Singleton Pattern, that makes that scanner unique on your code.

Then you can implement the methods you need or you can create a getScanner ( not recommended ) and you can control it with a private boolean, something like alreadyClosed.

If you are not aware how to use Singleton Pattern, here's a example:

public class Reader {
    
    
    private Scanner reader;
    private static Reader singleton = null;
    private boolean alreadyClosed;
    
    private Reader() {
        alreadyClosed = false;
        reader = new Scanner(System.in);
    }
    
    public static Reader getInstance() {
        if(singleton == null) {
            singleton = new Reader();
        }
        return singleton;
    }
    
    public int nextInt() throws AlreadyClosedException {
        if(!alreadyClosed) {
            return reader.nextInt();
        }
        throw new AlreadyClosedException(); //Custom exception
    }
    
    public double nextDouble() throws AlreadyClosedException {
        if(!alreadyClosed) {
            return reader.nextDouble();
        }
        throw new AlreadyClosedException();
    }
    
    public String nextLine() throws AlreadyClosedException {
        if(!alreadyClosed) {
            return reader.nextLine();
        }
        throw new AlreadyClosedException();
    }
    
    public void close() {
        alreadyClosed = true;
        reader.close();
    }   
}

Try It :

  DECLARE @String NVARCHAR(100)
    SET @String = '12354851'
    SELECT LEFT(@String, NULLIF(LEN(@String)-1,-1))

A few years late, but I'd like to add that if you need to do this in one fell swoop (like I did) you can set the config settings during the clone command. Try this:

git clone -c core.longpaths=true <your.url.here>

read reads until it finds a newline character or the end of file, and returns a non-zero exit code if it encounters an end-of-file. So it's quite possible for it to both read a line and return a non-zero exit code.

Consequently, the following code is not safe if the input might not be terminated by a newline:

while read LINE; do
  # do something with LINE
done

because the body of the while won't be executed on the last line.

Technically speaking, a file not terminated with a newline is not a text file, and text tools may fail in odd ways on such a file. However, I'm always reluctant to fall back on that explanation.

One way to solve the problem is to test if what was read is non-empty (-n):

while read -r LINE || [[ -n $LINE ]]; do
  # do something with LINE
done

Other solutions include using mapfile to read the file into an array, piping the file through some utility which is guaranteed to terminate the last line properly (grep ., for example, if you don't want to deal with blank lines), or doing the iterative processing with a tool like awk (which is usually my preference).

Note that -r is almost certainly needed in the read builtin; it causes read to not reinterpret \-sequences in the input.

Yeah, eclipse sees the top directory as the working/root directory, for the purposes of paths.

...just thought I'd add some extra info. I'm new here! I'd like to help.

    }

As far as the best algorithm goes you probably have it right. I would recommend that you unravel the recursive function and use a stack of your own (remember a stack overflow is the end of the world in a .Net 2.0+ app, the exception can not be caught IIRC).

The most important thing is that if you are using it in any form of a UI put it on a worker thread that signals the UI thread with updates.

If you run the mount command with no command-line arguments, which displays the file systems mounted on your system, you’ll notice a line that looks something like this: none on /dev/pts type devpts (rw,gid=5,mode=620) This indicates that a special type of file system, devpts , is mounted at /dev/pts .This file system, which isn’t associated with any hardware device, is a “magic” file system that is created by the Linux kernel. It’s similar to the /proc file system

Like the /dev directory, /dev/pts contains entries corresponding to devices. But unlike /dev , which is an ordinary directory, /dev/pts is a special directory that is cre- ated dynamically by the Linux kernel.The contents of the directory vary with time and reflect the state of the running system. The entries in /dev/pts correspond to pseudo-terminals (or pseudo-TTYs, or PTYs).

Linux creates a PTY for every new terminal window you open and displays a corre- sponding entry in /dev/pts .The PTY device acts like a terminal device—it accepts input from the keyboard and displays text output from the programs that run in it. PTYs are numbered, and the PTY number is the name of the corresponding entry in /dev/pts .

For example, if the new terminal window’s PTY number is 7, invoke this command from another window: % echo ‘I am a virtual di ’ > /dev/pts/7 The output appears in the new terminal window.

In java, DateFormatter by default uses DST,To avoid day Light saving (DST) you need to manually do a trick,
first you have to get the DST offset i.e. for how many millisecond DST applied, for ex somewhere DST is also for 45 minutes and for some places it is for 30 min
but in most cases DST is of 1 hour
you have to use Timezone object and check with the date whether it is falling under DST or not and then you have to manually add offset of DST into it. for eg:

 TimeZone tz = TimeZone.getTimeZone("EST");
 boolean isDST = tz.inDaylightTime(yourDateObj);
 if(isDST){
 int sec= tz.getDSTSavings()/1000;// for no. of seconds
 Calendar cal= Calendar.getInstance();
 cal.setTime(yourDateObj);
 cal.add(Calendar.Seconds,sec);
 System.out.println(cal.getTime());// your Date with DST neglected
  }

I found the answer to this problem here

Just do

mb_convert_encoding($data['name'], 'UTF-8', 'UTF-8');

I have another solution to do it without dynamic query. We can do it with the help of xquery as well.

    SET @Xml = cast(('<A>'+replace('3,4,22,6014',',' ,'</A><A>')+'</A>') AS XML)
    Select @Xml

    SELECT A.value('.', 'varchar(max)') as [Column] FROM @Xml.nodes('A') AS FN(A)

Here is the complete solution : http://raresql.com/2011/12/21/how-to-use-multiple-values-for-in-clause-using-same-parameter-sql-server/

Try getting the input stream from this you can then get the text data as so:-

    URL url;
    HttpURLConnection urlConnection = null;
    try {
        url = new URL("http://www.mysite.se/index.asp?data=99");

        urlConnection = (HttpURLConnection) url
                .openConnection();

        InputStream in = urlConnection.getInputStream();

        InputStreamReader isw = new InputStreamReader(in);

        int data = isw.read();
        while (data != -1) {
            char current = (char) data;
            data = isw.read();
            System.out.print(current);
        }
    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        if (urlConnection != null) {
            urlConnection.disconnect();
        }    
    }

You can probably use other inputstream readers such as buffered reader also.

The problem is that when you open the connection - it does not 'pull' any data.

Yes, assignment is supported for structs. However, there are problems:

struct S {
   char * p;
};

struct S s1, s2;
s1.p = malloc(100);
s2 = s1;

Now the pointers of both structs point to the same block of memory - the compiler does not copy the pointed to data. It is now difficult to know which struct instance owns the data. This is why C++ invented the concept of user-definable assignment operators - you can write specific code to handle this case.

If you want to compare two blocks of code / functions quickly you could do:

import timeit

start_time = timeit.default_timer()
func1()
print(timeit.default_timer() - start_time)

start_time = timeit.default_timer()
func2()
print(timeit.default_timer() - start_time)

A command like the one below will show three sections: request headers, response headers and data (separated by CRLF). It avoids technical information and syntactical noise added by curl.

curl -vs www.stackoverflow.com 2>&1 | sed '/^* /d; /bytes data]$/d; s/> //; s/< //'

The command will produce the following output:

Rather than Runtime.exec(String command), you need to use the exec(String command, String[] envp, File dir) method signature:

Process p =  Runtime.getRuntime().exec("cmd /c upsert.bat", null, new File("C:\\Program Files\\salesforce.com\\Data Loader\\cliq_process\\upsert"));

But personally, I'd use ProcessBuilder instead, which is a little more verbose but much easier to use and debug than Runtime.exec().

ProcessBuilder pb = new ProcessBuilder("cmd", "/c", "upsert.bat");
File dir = new File("C:/Program Files/salesforce.com/Data Loader/cliq_process/upsert");
pb.directory(dir);
Process p = pb.start();

In BOOTSTRAP 4 you can use

<div class="row m-0">
my fullwidth div
</div>

... if you just use a .row without the .m-0 as a top level div, you will have unwanted margin, which makes the page wider than the browser window and cause a horizontal scrollbar.

Double is a wrapper class,

The Double class wraps a value of the primitive type double in an object. An object of type Double contains a single field whose type is double.

In addition, this class provides several methods for converting a double to a String and a String to a double, as well as other constants and methods useful when dealing with a double.

The double data type,

The double data type is a double-precision 64-bit IEEE 754 floating point. Its range of values is 4.94065645841246544e-324d to 1.79769313486231570e+308d (positive or negative). For decimal values, this data type is generally the default choice. As mentioned above, this data type should never be used for precise values, such as currency.

Check each datatype with their ranges : Java's Primitive Data Types.

Important Note : If you'r thinking to use double for precise values, you need to re-think before using it. Java Traps: double

These messages are due to incorrect default value of core.autocrlf on Windows.

The concept of autocrlf is to handle line endings conversions transparently. And it does!

Bad news: value needs to be configured manually.
Good news: it should only be done ONE time per git installation (per project setting is also possible).

How autocrlf works:

core.autocrlf=true:      core.autocrlf=input:     core.autocrlf=false:
                                             
        repo                     repo                     repo
      ^      V                 ^      V                 ^      V
     /        \               /        \               /        \
crlf->lf    lf->crlf     crlf->lf       \             /          \      
   /            \           /            \           /            \

Here crlf = win-style end-of-line marker, lf = unix-style (and mac osx).

(pre-osx cr in not affected for any of three options above)

When does this warning show up (under Windows)

    – autocrlf = true if you have unix-style lf in one of your files (= RARELY),
    – autocrlf = input if you have win-style crlf in one of your files (= almost ALWAYS),
    – autocrlf = false – NEVER!

What does this warning mean

The warning "LF will be replaced by CRLF" says that you (having autocrlf=true) will lose your unix-style LF after commit-checkout cycle (it will be replaced by windows-style CRLF). Git doesn't expect you to use unix-style LF under windows.

The warning "CRLF will be replaced by LF" says that you (having autocrlf=input) will lose your windows-style CRLF after a commit-checkout cycle (it will be replaced by unix-style LF). Don't use input under windows.

Yet another way to show how autocrlf works

1) true:             x -> LF -> CRLF
2) input:            x -> LF -> LF
3) false:            x -> x -> x

where x is either CRLF (windows-style) or LF (unix-style) and arrows stand for

file to commit -> repository -> checked out file

How to fix

Default value for core.autocrlf is selected during git installation and stored in system-wide gitconfig (%ProgramFiles(x86)%\git\etc\gitconfig). Also there're (cascading in the following order):

   – "global" (per-user) gitconfig located at ~/.gitconfig, yet another
   – "global" (per-user) gitconfig at $XDG_CONFIG_HOME/git/config or $HOME/.config/git/config and
   – "local" (per-repo) gitconfig at .git/config in the working dir.

So, write git config core.autocrlf in the working dir to check the currently used value and

   – add autocrlf=false to system-wide gitconfig         # per-system solution
   – git config --global core.autocrlf false            # per-user solution
   – git config --local core.autocrlf false              # per-project solution

Warnings
– git config settings can be overridden by gitattributes settings.
– crlf -> lf conversion only happens when adding new files, crlf files already existing in the repo aren't affected.

Moral (for Windows):
    - use core.autocrlf = true if you plan to use this project under Unix as well (and unwilling to configure your editor/IDE to use unix line endings),
    - use core.autocrlf = false if you plan to use this project under Windows only (or you have configured your editor/IDE to use unix line endings),
    - never use core.autocrlf = input unless you have a good reason to (eg if you're using unix utilities under windows or if you run into makefiles issues),

PS What to choose when installing git for Windows?
If you're not going to use any of your projects under Unix, don't agree with the default first option. Choose the third one (Checkout as-is, commit as-is). You won't see this message. Ever.

PPS My personal preference is configuring the editor/IDE to use Unix-style endings, and setting core.autocrlf to false.

You have to first convert your object literal to a Prototype Hash:

// Store your object literal
var obj = {foo: 1, bar: 2, barobj: {75: true, 76: false, 85: true}}

// Iterate like so.  The $H() construct creates a prototype-extended Hash.
$H(obj).each(function(pair){
  alert(pair.key);
  alert(pair.value);
});

Building on @SotiriosDelimanolis's comment, here is a method to deal with URLs (such as file:...) and non-URLs (such as C:...), using Spring's FileSystemResource:

public FileSystemResource get(String file) {
    try {
        // First try to resolve as URL (file:...)
        Path path = Paths.get(new URL(file).toURI());
        FileSystemResource resource = new FileSystemResource(path.toFile());
        return resource;
    } catch (URISyntaxException | MalformedURLException e) {
        // If given file string isn't an URL, fall back to using a normal file 
        return new FileSystemResource(file);
    }
}

You need to use the file:/// protocol (yes, that's three slashes) if you want to link to local files.

<a href="file:///C:\Videos\lecture.mp4">Link 2</a>

These will never open the file in your local applications automatically. That's for security reasons which I'll cover in the last section. If it opens, it will only ever open in the browser. If your browser can display the file, it will, otherwise it will probably ask you if you want to download the file.

You cannot cross from http(s) to the file protocol

Modern versions of many browsers (e.g. Firefox and Chrome) will refuse to cross from the http(s) protocol to the file protocol to prevent malicious behaviour.

This means a webpage hosted on a website somewhere will never be able to link to files on your hard drive. You'll need to open your webpage locally using the file protocol if you want to do this stuff at all.

Why does it get stuck without file:///?

The first part of a URL is the protocol. A protocol is a few letters, then a colon and two slashes. HTTP:// and FTP:// are valid protocols; C:/ isn't and I'm pretty sure it doesn't even properly resemble one.

C:/ also isn't a valid web address. The browser could assume it's meant to be http://c/ with a blank port specified, but that's going to fail.

Your browser may not assume it's referring to a local file. It has little reason to make that assumption because webpages generally don't try to link to peoples' local files.

So if you want to access local files: tell it to use the file protocol.

Why three slashes?

Because it's part of the File URI scheme. You have the option of specifying a host after the first two slashes. If you skip specifying a host it will just assume you're referring to a file on your own PC. This means file:///C:/etc is a shortcut for file://localhost/C:/etc.

These files will still open in your browser and that is good

Your browser will respond to these files the same way they'd respond to the same file anywhere on the internet. These files will not open in your default file handler (e.g. MS Word or VLC Media Player), and you will not be able to do anything like ask File Explorer to open the file's location.

This is an extremely good thing for your security.

Sites in your browser cannot interact with your operating system very well. If a good site could tell your machine to open lecture.mp4 in VLC.exe, a malicious site could tell it to open virus.bat in CMD.exe. Or it could just tell your machine to run a few Uninstall.exe files or open File Explorer a million times.

This may not be convenient for you, but HTML and browser security weren't really designed for what you're doing. If you want to be able to open lecture.mp4 in VLC.exe consider writing a desktop application instead.

I suppose your p2vg table has also an id field , in that case , postgres cannot find if the id in the SELECT refers to vg or p2vg.

you should use SELECT(vg.id,vg.name) to remove ambiguity

Character only takes one value dude! like: char y = 'h'; and maybe you typed like char y = 'hello'; or smthg. good luck. for the question asked above the answer is pretty simple u have to use DOUBLE QUOTES to give a string value. easy enough;)

[ $(echo $variable_to_test | sed s/\n// | sed s/\ //) == "" ] && echo "String is empty"

Stripping all newlines and spaces from the string will cause a blank one to be reduced to nothing which can be tested and acted upon

This is what worked for me: Using Gradle 4.8.1

buildscript {
    ext.kotlin_version = '1.1.1' 
repositories {
    jcenter()
    google()
}
dependencies {
    classpath 'com.android.tools.build:gradle:3.1.0'}
}
allprojects {
    repositories {
        mavenLocal()
        jcenter()
        google()
        maven {
            url "$rootDir/../node_modules/react-native/android"
        }
    maven {
            url 'https://dl.bintray.com/kotlin/kotlin-dev/'
    }
  }
}   

Based on the above post i tried this and this worked fine I wanted to use the value of Map B as keys for Map A:

<c:if test="${not empty activityCodeMap and not empty activityDescMap}">
<c:forEach var="valueMap" items="${auditMap}">
<tr>
<td class="activity_white"><c:out value="${activityCodeMap[valueMap.value.activityCode]}"/></td>
<td class="activity_white"><c:out value="${activityDescMap[valueMap.value.activityDescCode]}"/></td>
<td class="activity_white">${valueMap.value.dateTime}</td>
</tr>
</c:forEach>
</c:if>

if you have number of columns in your database table more than number of columns in your csv you can proceed like this:

LOAD DATA LOCAL INFILE 'pathOfFile.csv'
INTO TABLE youTable 
CHARACTER SET latin1 FIELDS TERMINATED BY ';' #you can use ',' if you have comma separated
OPTIONALLY ENCLOSED BY '"' 
ESCAPED BY '\\' 
LINES TERMINATED BY '\r\n'
(yourcolumn,yourcolumn2,yourcolumn3,yourcolumn4,...);

Quite Xcode and Open it again, it will show. For me it's worked.

I would say it has capabilities to seem OO. Especially if you take advantage of it's ability to create methods on an existing object (anonymous methods in some languages). Client script libraries like jquery (jquery.com) or prototype (prototypejs.org) are good examples of libraries taking advantage of this, making javascript behave pretty OO-like.

There are no post/pre increment/decrement operators in python like in languages like C.

We can see ++ or -- as multiple signs getting multiplied, like we do in maths (-1) * (-1) = (+1).

E.g.

---count

Parses as

-(-(-count)))

Which translates to

-(+count)

Because, multiplication of - sign with - sign is +

And finally,

-count

FYI, I put together a JSFiddle of this using the $cookieStore, two controllers, a $rootScope, and AngularjS 1.0.6. It's on JSFifddle as http://jsfiddle.net/krimple/9dSb2/ as a base if you're messing around with this...

The gist of it is:

Javascript

var myApp = angular.module('myApp', ['ngCookies']);

myApp.controller('CookieCtrl', function ($scope, $rootScope, $cookieStore) {
    $scope.bump = function () {
        var lastVal = $cookieStore.get('lastValue');
        if (!lastVal) {
            $rootScope.lastVal = 1;
        } else {
            $rootScope.lastVal = lastVal + 1;
        }
        $cookieStore.put('lastValue', $rootScope.lastVal);
    }
});

myApp.controller('ShowerCtrl', function () {
});

HTML

<div ng-app="myApp">
    <div id="lastVal" ng-controller="ShowerCtrl">{{ lastVal }}</div>
    <div id="button-holder" ng-controller="CookieCtrl">
        <button ng-click="bump()">Bump!</button>
    </div>
</div>

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

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

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

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

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

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

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

In my current case it is printing:

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

Hope it can be helpful.

If you're using Spring Boot, the simplest way to disable the Spring Security default headers is to use security.headers.* properties. In particular, if you want to disable the X-Frame-Options default header, just add the following to your application.properties:

security.headers.frame=false

There is also security.headers.cache, security.headers.content-type, security.headers.hsts and security.headers.xss properties that you can use. For more information, take a look at SecurityProperties.

You can do the following to learn/test the concept:

1. Open new Excel Workbook and in Excel VBA editor right-click on Modules->Insert->Module

2. In newly added Module1 add the declaration; Public Global1 As String

3. in Worksheet VBA Module Sheet1(Sheet1) put the code snippet:

Sub setMe()
      Global1 = "Hello"
End Sub

4. in Worksheet VBA Module Sheet2(Sheet2) put the code snippet:

Sub showMe()
    Debug.Print (Global1)
End Sub

5. Run in sequence Sub setMe() and then Sub showMe() to test the global visibility/accessibility of the var Global1

Hope this will help.

Instead of using <hr>, you can one of the border of the enclosing block and display it as a horizontal line.

Here is a sample code:

The HTML:

<div class="title_block">
    <h3>This is a header.</h3>
</div>
<p>Here is some sample paragraph text.<br>
This demonstrates that a horizontal line goes between the title and the paragraph.</p>

The CSS:

.title_block {
    border-bottom: 1px solid #ddd;
    padding-bottom: 5px;
    margin-bottom: 5px;
}

Encode URL String

    var url = $(location).attr('href'); //get current url
    //OR
    var url = 'folder/index.html?param=#23dd&noob=yes'; //or specify one

var encodedUrl = encodeURIComponent(url);
console.log(encodedUrl);
//outputs folder%2Findex.html%3Fparam%3D%2323dd%26noob%3Dyes

The only way to return the data from the function would be to make a synchronous call instead of an asynchronous call, but that would freeze up the browser while it's waiting for the response.

You can pass in a callback function that handles the result:

function testAjax(handleData) {
  $.ajax({
    url:"getvalue.php",  
    success:function(data) {
      handleData(data); 
    }
  });
}

Call it like this:

testAjax(function(output){
  // here you use the output
});
// Note: the call won't wait for the result,
// so it will continue with the code here while waiting.

Assuming your dataObject is defined the way you specified, you do this:

var dataArray = [];
for (var key in dataObject)
    dataArray.push(dataObject[key]);

And end up having dataArray populated with inner objects.

Threads > switch "Main" to "app"

In the "Threads" section I changed the context from "Main" > to "app". The "app" should have a blue arrow aside.

You need to bind the modal hide call to the onclick event.

Assuming you are using jQuery you can do that with:

$('#closemodal').click(function() {
    $('#modalwindow').modal('hide');
});

Also make sure the click event is bound after the document has finished loading:

$(function() {
   // Place the above code inside this block
});
enter code here

The nested class doesn't know about the outer class, and protected doesn't help. You'll have to pass some actual reference to objects of the nested class type. You could store a foo*, but perhaps a reference to the integer is enough:

class Outer
{
    int n;

public:
    class Inner
    {
        int & a;
    public:
        Inner(int & b) : a(b) { }
        int & get() { return a; }
    };

    // ...  for example:

    Inner inn;
    Outer() : inn(n) { }
};

Now you can instantiate inner classes like Inner i(n); and call i.get().

Based on easy-confirm-plugin i did it:

(function($) {
    $.postconfirm = {};
    $.postconfirm.locales = {};
    $.postconfirm.locales.ptBR = {
        title: 'Esta certo disto?',
        text: 'Esta certo que quer realmente ?',
        button: ['Cancela', 'Confirma'],
        closeText: 'fecha'
    };
    $.fn.postconfirm = function(options) {
        var options = jQuery.extend({
            eventType: 'click',
            icon: 'help'
        }, options);
        var locale = jQuery.extend({}, $.postconfirm.locales.ptBR, options.locale);
        var type = options.eventType;
        return this.each(function() {
            var target = this;
            var $target = jQuery(target);
            var getDlgDv = function() {
                var dlger = (options.dialog === undefined || typeof(options.dialog) != 'object');
                var dlgdv = $('<div class="dialog confirm">' + locale.text + '</div>');         
                return dlger ? dlgdv : options.dialog;          
            }           
            var dialog = getDlgDv();
            var handler = function(event) {
                    $(dialog).dialog('open');
                    event.stopImmediatePropagation();
                    event.preventDefault();
                    return false;
            };
            var init = function() 
            {
                $target.bind(type, handler); 
            };
            var buttons = {};
            buttons[locale.button[0]] = function() { $(dialog).dialog("close"); };
            buttons[locale.button[1]] = function() {
                $(dialog).dialog("close");
                alert('1');
                $target.unbind(type, handler);
                $target.click();
                $target.attr("disabled", true);
            };            
            $(dialog).dialog({
                autoOpen: false,
                resizable: false,
                draggable: true,
                closeOnEscape: true,
                width: 'auto',
                minHeight: 120,
                maxHeight: 200,
                buttons: buttons,
                title: locale.title,
                closeText: locale.closeText,
                modal: true
            });
            init();
        });
        var _attr = $.fn.attr;
        $.fn.attr = function(attr, value) {
            var returned = _attr.apply(this, arguments);
            if (attr == 'title' && returned === undefined) 
            {
                returned = '';
            }
            return returned;
        };
    };
})(jQuery);

you only need call in this way:

    <script type="text/javascript">     
        $(document).ready(function () {
            $(".mybuttonselector").postconfirm({ locale: {
                        title: 'title',
                        text: 'message',
                        button: ['bt_0', 'bt_1'],
                        closeText: 'X'
                    }
                });
        });
    </script>

If you're using jQuery 1.5, then statusCode will work.

If you're using jQuery 1.4, try this:

error: function(jqXHR, textStatus, errorThrown) {
    alert(jqXHR.status);
    alert(textStatus);
    alert(errorThrown);
}

You should see the status code from the first alert.

The accepted answer does not correctly dispose the WebResponse or decode the text. Also, there's a new way to do this in .NET 4.5.

To perform an HTTP GET and read the response text, do the following.

.NET 1.1 - 4.0

public static string GetResponseText(string address)
{
    var request = (HttpWebRequest)WebRequest.Create(address);

    using (var response = (HttpWebResponse)request.GetResponse())
    {
        var encoding = Encoding.GetEncoding(response.CharacterSet);

        using (var responseStream = response.GetResponseStream())
        using (var reader = new StreamReader(responseStream, encoding))
            return reader.ReadToEnd();
    }
}

.NET 4.5

private static readonly HttpClient httpClient = new HttpClient();

public static async Task<string> GetResponseText(string address)
{
    return await httpClient.GetStringAsync(address);
}

make sure your css reads:

margin: 0 auto;

Even though you're saying you have the left and right set to auto, you may be placing an error. Of course we wouldn't know though because you did not show us any code.

Jérôme Petazzoni has a pretty interesting blog post on how to Attach a volume to a container while it is running. This isn't something that's built into Docker out of the box, but possible to accomplish.

As he also points out

This will not work on filesystems which are not based on block devices.

It will only work if /proc/mounts correctly lists the block device node (which, as we saw above, is not necessarily true).

Also, I only tested this on my local environment; I didn’t even try on a cloud instance or anything like that

YMMV

It's even possible to restore without creating a blank database at all.

In Sql Server Management Studio, right click on Databases and select Restore Database...

In the Restore Database dialog, select the Source Database or Device as normal. Once the source database is selected, SSMS will populate the destination database name based on the original name of the database.

It's then possible to change the name of the database and enter a new destination database name.

With this approach, you don't even need to go to the Options tab and click the "Overwrite the existing database" option.

Also, the database files will be named consistently with your new database name and you still have the option to change file names if you want.

If you are writing xml, just use the classes provided by the framework to create the xml. You won't have to bother with escaping or anything.

Console.Write(new XElement("Data", "< > &"));

Will output

<Data>&lt; &gt; &amp;</Data>

If you need to read an XML file that is malformed, do not use regular expression. Instead, use the Html Agility Pack.

You could do this manually or using IndexOf method.

Manually:

int index = 43;
string piece = myString.Substring(index);

Using IndexOf you can see where the fullstop is:

int index = myString.IndexOf(".") + 1;
string piece = myString.Substring(index);

For page object model -

 @FindBy(xpath="//foo")
   public WebElement textBox;

now in your function

 public void clearExistingText(String newText){
    textBox.clear();
    textBox.sendKeys(newText);
  }

for general selenium architecture -

driver.findElement(By.xpath("//yourxpath")).clear();
driver.findElement(By.xpath("//yourxpath")).sendKeys("newText");

Here's a shell script I wrote for the use case of a single subdirectory sparse checkout

coSubDir.sh

localRepo=$1
remoteRepo=$2
subDir=$3


# Create local repository for subdirectory checkout, make it hidden to avoid having to drill down to the subfolder
mkdir ./.$localRepo
cd ./.$localRepo
git init
git remote add -f origin $remoteRepo
git config core.sparseCheckout true

# Add the subdirectory of interest to the sparse checkout.
echo $subDir >> .git/info/sparse-checkout

git pull origin master

# Create convenience symlink to the subdirectory of interest
cd ..
ln -s ./.$localRepo/$subDir $localRepo

One more (idio(ma)tic) way:

URL.split("/")[-1]

try using

import mainLogo from'./logoWhite.png';

//then in the render function of Jsx insert the mainLogo variable

class NavBar extends Component {
  render() {
    return (
      <nav className="nav" style={nbStyle}>
        <div className="container">
          //right below here
          <img  src={mainLogo} style={nbStyle.logo} alt="fireSpot"/>
        </div>
      </nav>
    );
  }
}

Maybe more clear:

Note that precision is the total number of digits, scale included

NUMBER(Precision,Scale)

Precision 8, scale 3 : 87654.321

Precision 5, scale 3 : 54.321

Precision 5, scale 1 : 5432.1

Precision 5, scale 0 : 54321

Precision 5, scale -1: 54320

Precision 5, scale -3: 54000

In System.Web.Mvc.Html ( in System.Web.Mvc.dll ) the begin form is defined like:- Details

BeginForm ( this HtmlHelper htmlHelper, string actionName, string
controllerName, object routeValues, FormMethod method, object htmlAttributes)

Means you should use like this :

Html.BeginForm( string actionName, string controllerName,object routeValues, FormMethod method, object htmlAttributes)

So, it worked in MVC 4

@using (Html.BeginForm(null, null, new { @id = string.Empty }, FormMethod.Post,
    new { @id = "signupform" }))
{
    <input id="TRAINER_LIST" name="TRAINER_LIST" type="hidden" value="">
    <input type="submit" value="Create" id="btnSubmit" />
}

Just git commit it.

Optionally git abort it:

If you want to save the workbook with the macros use the below code

if you want to save workbook with no macros and no pop-up use this

Sub save()
    Application.DisplayAlerts = False
    ActiveWorkbook.SaveAs Filename:="C:\Users\" & Environ$("username") & _

I think I use the simplest method to get the full profile picture. You can get full profile picture or you can set the profile picture dimension yourself:

$facebook->api(me?fields=picture.width(800).height(800))

You can set width and height as per your need. Though Facebook doesn't return the exact size asked for, It returns the closest dimension picture available with them.

This is an old question but I came across another solution not yet listed.

You can use the Object.assign function to get the desired output:

var output = Object.assign([], "Hello, world!");_x000D_
console.log(output);_x000D_
    // [ 'H', 'e', 'l', 'l', 'o', ',', ' ', 'w', 'o', 'r', 'l', 'd', '!' ]

Not necessarily right or wrong, just another option.

Object.assign is described well at the MDN site.

If both the list are too big and when we use lamda expression then it will take a long time to fetch . Better to use linq in this case to fetch parameters list:

var items = (from x in parameters
                join y in myStrings on x.Source equals y
                select x)
            .ToList();

The accepted answer (https://stackoverflow.com/a/41348219/4974715) is not realistically maintainable or suitable because "CanReadResource" is being used as a claim (but should essentially be a policy in reality, IMO). The approach at the answer is not OK in the way it was used, because if an action method requires many different claims setups, then with that answer you would have to repeatedly write something like...

[ClaimRequirement(MyClaimTypes.Permission, "CanReadResource")] 
[ClaimRequirement(MyClaimTypes.AnotherPermision, "AnotherClaimVaue")]
//and etc. on a single action.

So, imagine how much coding that would take. Ideally, "CanReadResource" is supposed to be a policy that uses many claims to determine if a user can read a resource.

What I do is I create my policies as an enumeration and then loop through and set up the requirements like thus...

services.AddAuthorization(authorizationOptions =>
        {
            foreach (var policyString in Enum.GetNames(typeof(Enumerations.Security.Policy)))
            {
                authorizationOptions.AddPolicy(
                    policyString,
                    authorizationPolicyBuilder => authorizationPolicyBuilder.Requirements.Add(new DefaultAuthorizationRequirement((Enumerations.Security.Policy)Enum.Parse(typeof(Enumerations.Security.Policy), policyWrtString), DateTime.UtcNow)));

      /* Note that thisn does not stop you from 
          configuring policies directly against a username, claims, roles, etc. You can do the usual.
     */
            }
        }); 

The DefaultAuthorizationRequirement class looks like...

public class DefaultAuthorizationRequirement : IAuthorizationRequirement
{
    public Enumerations.Security.Policy Policy {get; set;} //This is a mere enumeration whose code is not shown.
    public DateTime DateTimeOfSetup {get; set;} //Just in case you have to know when the app started up. And you may want to log out a user if their profile was modified after this date-time, etc.
}

public class DefaultAuthorizationHandler : AuthorizationHandler<DefaultAuthorizationRequirement>
{
    private IAServiceToUse _aServiceToUse;

    public DefaultAuthorizationHandler(
        IAServiceToUse aServiceToUse
        )
    {
        _aServiceToUse = aServiceToUse;
    }

    protected async override Task HandleRequirementAsync(AuthorizationHandlerContext context, DefaultAuthorizationRequirement requirement)
    {
        /*Here, you can quickly check a data source or Web API or etc. 
           to know the latest date-time of the user's profile modification...
        */
        if (_aServiceToUse.GetDateTimeOfLatestUserProfileModication > requirement.DateTimeOfSetup)
        {
            context.Fail(); /*Because any modifications to user information, 
            e.g. if the user used another browser or if by Admin modification, 
            the claims of the user in this session cannot be guaranteed to be reliable.
            */
            return;
        }

        bool shouldSucceed = false; //This should first be false, because context.Succeed(...) has to only be called if the requirement specifically succeeds.

        bool shouldFail = false; /*This should first be false, because context.Fail() 
        doesn't have to be called if there's no security breach.
        */

        // You can do anything.
        await doAnythingAsync();

       /*You can get the user's claims... 
          ALSO, note that if you have a way to priorly map users or users with certain claims 
          to particular policies, add those policies as claims of the user for the sake of ease. 
          BUT policies that require dynamic code (e.g. checking for age range) would have to be 
          coded in the switch-case below to determine stuff.
       */

        var claims = context.User.Claims;

        // You can, of course, get the policy that was hit...
        var policy = requirement.Policy

        //You can use a switch case to determine what policy to deal with here...
        switch (policy)
        {
            case Enumerations.Security.Policy.CanReadResource:
                 /*Do stuff with the claims and change the 
                     value of shouldSucceed and/or shouldFail.
                */
                 break;
            case Enumerations.Security.Policy.AnotherPolicy:
                 /*Do stuff with the claims and change the 
                    value of shouldSucceed and/or shouldFail.
                 */
                 break;
                // Other policies too.

            default:
                 throw new NotImplementedException();
        }

        /* Note that the following conditions are 
            so because failure and success in a requirement handler 
            are not mutually exclusive. They demand certainty.
        */

        if (shouldFail)
        {
            context.Fail(); /*Check the docs on this method to 
            see its implications.
            */
        }                

        if (shouldSucceed)
        {
            context.Succeed(requirement); 
        } 
     }
}

Note that the code above can also enable pre-mapping of a user to a policy in your data store. So, when composing claims for the user, you basically retrieve the policies that had been pre-mapped to the user directly or indirectly (e.g. because the user has a certain claim value and that claim value had been identified and mapped to a policy, such that it provides automatic mapping for users who have that claim value too), and enlist the policies as claims, such that in the authorization handler, you can simply check if the user's claims contain requirement.Policy as a Value of a Claim item in their claims. That is for a static way of satisfying a policy requirement, e.g. "First name" requirement is quite static in nature. So, for the example above (which I had forgotten to give example on Authorize attribute in my earlier updates to this answer), using the policy with Authorize attribute is like as follows, where ViewRecord is an enum member:

[Authorize(Policy = nameof(Enumerations.Security.Policy.ViewRecord))] 

A dynamic requirement can be about checking age range, etc. and policies that use such requirements cannot be pre-mapped to users.

An example of dynamic policy claims checking (e.g. to check if a user is above 18 years old) is already at the answer given by @blowdart (https://stackoverflow.com/a/31465227/4974715).

PS: I typed this on my phone. Pardon any typos and lack of formatting.

You can use the ant-contrib task "for" to iterate on the list of files separate by any delimeter, default delimeter is ",".

Following is the sample file which shows this:

<project name="modify-files" default="main" basedir=".">
    <taskdef resource="net/sf/antcontrib/antlib.xml"/>
    <target name="main">
        <for list="FileA,FileB,FileC,FileD,FileE" param="file">
          <sequential>
            <echo>Updating file: @{file}</echo>
            <!-- Do something with file here -->
          </sequential>
        </for>                         
    </target>
</project>

By default, the datetime object is naive in Python, so you need to make both of them either naive or aware datetime objects. This can be done using:

import datetime
import pytz

utc=pytz.UTC

challenge.datetime_start = utc.localize(challenge.datetime_start) 
challenge.datetime_end = utc.localize(challenge.datetime_end) 
# now both the datetime objects are aware, and you can compare them

Note: This would raise a ValueError if tzinfo is already set. If you are not sure about that, just use

start_time = challenge.datetime_start.replace(tzinfo=utc)
end_time = challenge.datetime_end.replace(tzinfo=utc)

BTW, you could format a UNIX timestamp in datetime.datetime object with timezone info as following

d = datetime.datetime.utcfromtimestamp(int(unix_timestamp))
d_with_tz = datetime.datetime(
    year=d.year,
    month=d.month,
    day=d.day,
    hour=d.hour,
    minute=d.minute,
    second=d.second,
    tzinfo=pytz.UTC)

The problem is that you are not tracking the files locally but identical files are tracked remotely so in order to "pull" your system would be forced to overwrite the local files which are not version controlled.

Try running

git add * 
git stash
git pull

This will track all files, remove all of your local changes to those files, and then get the files from the server.

As one of the possible codes

    echo off
    for /f "usebackq tokens=* delims= " %%x in (`chdir`) do set var=%var% %%x
    echo The current directory is: "%var:~1%"

When I was trying to add another flavour I face same situation.

I found in one of post and I gave successful try and it work. Following I did: File -> Invalidate Cached/Restart.

Its seems that server is not running properly so ensure that with terminal by

telnet ip port

example

telnet localhost 8069

It will return connected to localhost so it indicates that there is no problem with the connection Else it will return Connection refused it indicates that there is problem with the connection

1) setState actions are asynchronous and are batched for performance gains. This is explained in the documentation of setState.

setState() does not immediately mutate this.state but creates a pending state transition. Accessing this.state after calling this method can potentially return the existing value. There is no guarantee of synchronous operation of calls to setState and calls may be batched for performance gains.

2) Why would they make setState async as JS is a single threaded language and this setState is not a WebAPI or server call?

This is because setState alters the state and causes rerendering. This can be an expensive operation and making it synchronous might leave the browser unresponsive.

Thus the setState calls are asynchronous as well as batched for better UI experience and performance.

Yes. Use the Tag Editor. You can click through to manage individual resources.

https://docs.aws.amazon.com/awsconsolehelpdocs/latest/gsg/tag-editor.html

public static Date getDateByString(String dateTime) {
        if(dateTime==null || dateTime.isEmpty()) {
            return null;
        }
        else{
            String modified = dateTime + ".000+0000";
            DateFormat formatter = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSZ");
            Date dateObj = new Date();
            Date dateObj1 = new Date();
            try {
                if (dateTime != null) {
                    dateObj = formatter.parse(modified);
                }

            } catch (ParseException e) {
                e.printStackTrace();
            }

            return dateObj;
        }

    }

Figured it out, folks! for the NAME of the text box, you have to use "q". I had "g" just for my own personal preferences. But apparently it has to be "q".

Anyone know why?

Should be in

Program Files>Microsoft SQL Server>MSSQL 1.0>MSSQL>BACKUP>

In my case it is

C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\Backup

If you use the gui or T-SQL you can specify where you want it T-SQL example

BACKUP DATABASE [YourDB] TO  DISK = N'SomePath\YourDB.bak' 
WITH NOFORMAT, NOINIT,  NAME = N'YourDB Full Database Backup', 
SKIP, NOREWIND, NOUNLOAD,  STATS = 10
GO

With T-SQL you can also get the location of the backup, see here Getting the physical device name and backup time for a SQL Server database

SELECT          physical_device_name,
                backup_start_date,
                backup_finish_date,
                backup_size/1024.0 AS BackupSizeKB
FROM msdb.dbo.backupset b
JOIN msdb.dbo.backupmediafamily m ON b.media_set_id = m.media_set_id
WHERE database_name = 'YourDB'
ORDER BY backup_finish_date DESC

• Deep copy: Clone this object and every reference to every other object it has
• Shallow copy: Clone this object and keep its references
• Object clone() throws CloneNotSupportedException: It is not specified whether this should return a deep or shallow copy, but at the very least: o.clone() != o

What @JosephSilber said, or pass the $event object into ng-click callback and stop the propagation inside of it:

<div ng-controller="OverlayCtrl" class="overlay" ng-click="hideOverlay()">
  <img src="http://some_src" ng-click="nextImage($event)"/>
</div>

$scope.nextImage = function($event) {
  $event.stopPropagation();
  // Some code to find and display the next image
}

Your code should read -

String kk = wd.findElement(By.cssSelector("div[id^='customSelect'] span.selectLabel")).getText();

Use CSS. it's much cleaner and easier.. Let me know if that solves your issue.

@albert's solution was the closest I think but it can only parse up to 3 byte utf-8 characters

function utf8ArrayToStr(array) {
  var out, i, len, c;
  var char2, char3;

  out = "";
  len = array.length;
  i = 0;

  // XXX: Invalid bytes are ignored
  while(i < len) {
    c = array[i++];
    if (c >> 7 == 0) {
      // 0xxx xxxx
      out += String.fromCharCode(c);
      continue;
    }

    // Invalid starting byte
    if (c >> 6 == 0x02) {
      continue;
    }

    // #### MULTIBYTE ####
    // How many bytes left for thus character?
    var extraLength = null;
    if (c >> 5 == 0x06) {
      extraLength = 1;
    } else if (c >> 4 == 0x0e) {
      extraLength = 2;
    } else if (c >> 3 == 0x1e) {
      extraLength = 3;
    } else if (c >> 2 == 0x3e) {
      extraLength = 4;
    } else if (c >> 1 == 0x7e) {
      extraLength = 5;
    } else {
      continue;
    }

    // Do we have enough bytes in our data?
    if (i+extraLength > len) {
      var leftovers = array.slice(i-1);

      // If there is an invalid byte in the leftovers we might want to
      // continue from there.
      for (; i < len; i++) if (array[i] >> 6 != 0x02) break;
      if (i != len) continue;

      // All leftover bytes are valid.
      return {result: out, leftovers: leftovers};
    }
    // Remove the UTF-8 prefix from the char (res)
    var mask = (1 << (8 - extraLength - 1)) - 1,
        res = c & mask, nextChar, count;

    for (count = 0; count < extraLength; count++) {
      nextChar = array[i++];

      // Is the char valid multibyte part?
      if (nextChar >> 6 != 0x02) {break;};
      res = (res << 6) | (nextChar & 0x3f);
    }

    if (count != extraLength) {
      i--;
      continue;
    }

    if (res <= 0xffff) {
      out += String.fromCharCode(res);
      continue;
    }

    res -= 0x10000;
    var high = ((res >> 10) & 0x3ff) + 0xd800,
        low = (res & 0x3ff) + 0xdc00;
    out += String.fromCharCode(high, low);
  }

  return {result: out, leftovers: []};
}

This returns {result: "parsed string", leftovers: [list of invalid bytes at the end]} in case you are parsing the string in chunks.

EDIT: fixed the issue that @unhammer found.

I wrote a code used to count vowels. You may use this to count any character of your choosing. I hope this helps! (coded in Python 3.6.0)

while(True):
phrase = input('Enter phrase you wish to count vowels: ')
if phrase == 'end': #This will to be used to end the loop 
    quit() #You may use break command if you don't wish to quit
lower = str.lower(phrase) #Will make string lower case
convert = list(lower) #Convert sting into a list
a = convert.count('a') #This will count letter for the letter a
e = convert.count('e')
i = convert.count('i')
o = convert.count('o')
u = convert.count('u')

vowel = a + e + i + o + u #Used to find total sum of vowels

print ('Total vowels = ', vowel)
print ('a = ', a)
print ('e = ', e)
print ('i = ', i)
print ('o = ', o)
print ('u = ', u)

Another option is to use Promise.all to wait for an array of promises to resolve and then act on those.

Code below shows how to wait for all the promises to resolve and then deal with the results once they are all ready (as that seemed to be the objective of the question); Also for illustrative purposes, it shows output during execution (end finishes before middle).

function append_output(suffix, value) {
  $("#output_"+suffix).append(value)
}

function kickOff() {
  let start = new Promise((resolve, reject) => {
    append_output("now", "start")
    resolve("start")
  })
  let middle = new Promise((resolve, reject) => {
    setTimeout(() => {
      append_output("now", " middle")
      resolve(" middle")
    }, 1000)
  })
  let end = new Promise((resolve, reject) => {
    append_output("now", " end")
    resolve(" end")
  })

  Promise.all([start, middle, end]).then(results => {
    results.forEach(
      result => append_output("later", result))
  })
}

kickOff()

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
Updated during execution: <div id="output_now"></div>
Updated after all have completed: <div id="output_later"></div>

This variant is better because you could not know whether file exists or not. You should send correct header when you know for certain that you can read contents of your file. Also, if you have branches of code that does not finish with '.end()', browser will wait until it get them. In other words, your browser will wait a long time.

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

function start(resp) {

    fs.readFile(filename, "utf8", function(err, data) {
        if (err) {
            // may be filename does not exists?
            resp.writeHead(404, {
                'Content-Type' : 'text/html'
            });
            // log this error into browser
            resp.write(err.toString());
            resp.end();
        } else {

            resp.writeHead(200, {
                "Content-Type": "text/html"
            });      
            resp.write(data.toString());
            resp.end();
        }
    });
}

Two options save vijay.sql

declare
begin
execute immediate 
'CREATE TABLE DMS_POP_WKLY_REFRESH_'||to_char(sysdate,'YYYYMMDD')||' NOLOGGING PARALLEL AS
SELECT wk.*,bbc.distance_km ,NVL(bbc.tactical_broadband_offer,0) tactical_broadband_offer ,
       sel.tactical_select_executive_flag,
       sel.agent_name,
       res.DMS_RESIGN_CAMPAIGN_CODE,
       pclub.tactical_select_flag
FROM   spineowner.pop_wkly_refresh_20100201 wk,
       dms_bb_coverage_102009 bbc,

       DMS_RESIGN_CAMPAIGN_26052009 res,
       DMS_PRIORITY_CLUB pclub
WHERE  wk.mpn = bbc.mpn(+)
AND    wk.mpn = sel.mpn (+)
AND    wk.mpn = res.mpn (+)
AND    wk.mpn = pclub.mpn (+)'
end;
/

The above will generate table names automatically based on sysdate. If you still need to pass as variable, then save vijay.sql as

declare
begin
execute immediate 
'CREATE TABLE DMS_POP_WKLY_REFRESH_'||&1||' NOLOGGING PARALLEL AS
SELECT wk.*,bbc.distance_km ,NVL(bbc.tactical_broadband_offer,0) tactical_broadband_offer ,

I'm doing the following:

getLocalStorageSizeLimit = function () {

    var maxLength = Math.pow(2,24);
    var preLength = 0;
    var hugeString = "0";
    var testString;
    var keyName = "testingLengthKey";

    //2^24 = 16777216 should be enough to all browsers
    testString = (new Array(Math.pow(2, 24))).join("X");

    while (maxLength !== preLength) {
        try  {
            localStorage.setItem(keyName, testString);

            preLength = testString.length;
            maxLength = Math.ceil(preLength + ((hugeString.length - preLength) / 2));

            testString = hugeString.substr(0, maxLength);
        } catch (e) {
            hugeString = testString;

            maxLength = Math.floor(testString.length - (testString.length - preLength) / 2);
            testString = hugeString.substr(0, maxLength);
        }
    }

    localStorage.removeItem(keyName);

    maxLength = JSON.stringify(this.storageObject).length + maxLength + keyName.length - 2;

    return maxLength;
};

the error can be due to one of several missing package. Below command will install several packages like g++, gcc, etc.

sudo apt-get install build-essential

I was tired of searching on google how to run iReport with java 8.

I did everything as said on the Internet,But I don't know why they weren't work for me.

Then I Change My Computer JDK Current Version form 1.8 to 1.7 Using Registry Editor.

Now it work fine.

To Change Current Version

Start => Type regedit (Press Enter) => HKEY_LOCAL_MACHINE => SOFTWARE => JavaSoft => Java Development Kit => Change Key Value of CurrentVersion From 1.8 to 1.7

You could try scraping whatever you need with PHP or another server side language, then put the iframe to the scraped content. Here's an example with PHP:

scrapedcontent.php:

<?php
$homepage = file_get_contents('http://www.example.com/');
echo $homepage;
?>

index.html:

<iframe src="scrapedcontent.php"></iframe>

([my double-compatible primitive type here])(Math.random() * [my max value here] * (Math.random() > 0.5 ? 1 : -1))

example:

// need a random number between -500 and +500
long myRandomLong = (long)(Math.random() * 500 * (Math.random() > 0.5 ? 1 : -1));

You don't need to convert your dates to timestamp before the sorting, but it's a good idea though because it will take more time to sort without it.

$data = array(
    array(
        "title" => "Another title",
        "date"  => "Fri, 17 Jun 2011 08:55:57 +0200"
    ),
    array(
        "title" => "My title",
        "date"  => "Mon, 16 Jun 2010 06:55:57 +0200"
    )
);

function sortFunction( $a, $b ) {
    return strtotime($a["date"]) - strtotime($b["date"]);
}
usort($data, "sortFunction");
var_dump($data);

You can use "Gena" library. It closely resembles stl::vector in pure C89.

From the README, it features:

• Access vector elements just like plain C arrays: vec[k][j];
• Have multi-dimentional arrays;
• Copy vectors;
• Instantiate necessary vector types once in a separate module, instead of doing this every time you needed a vector;
• You can choose how to pass values into a vector and how to return them from it: by value or by pointer.

You can check it out here:

https://github.com/cher-nov/Gena

I think the solution is just as simple as this:

Card temp = deck[cardAindex];
deck[cardAIndex]=deck[cardBIndex]; 
deck[cardBIndex]=temp;

$myArr = array();

function someFuntion(array $myArr) {
    $myVal = //some processing here to determine value of $myVal
    $myArr[] = $myVal;

    return $myArr;
}

$myArr = someFunction($myArr);

If it's not the Home edition of XP, you can use \\servername\c$

Just in case anyone arrives here and was hoping for VB (I did, and I didn't enter c# as a search term), here's the basics of the first response..

Public Shared Function ConvertDataTableToHTML(dt As DataTable) As String
    Dim html As String = "<table>"
    html += "<tr>"
    For i As Integer = 0 To dt.Columns.Count - 1
        html += "<td>" + System.Web.HttpUtility.HtmlEncode(dt.Columns(i).ColumnName) + "</td>"
    Next
    html += "</tr>"
    For i As Integer = 0 To dt.Rows.Count - 1
        html += "<tr>"
        For j As Integer = 0 To dt.Columns.Count - 1
            html += "<td>" + System.Web.HttpUtility.HtmlEncode(dt.Rows(i)(j).ToString()) + "</td>"
        Next
        html += "</tr>"
    Next
    html += "</table>"
    Return html
End Function

You are referring to the type rather than the instance. Make 'Model' lowercase in the example in your second and fourth code samples.

Model.GetHtmlAttributes

should be

model.GetHtmlAttributes

Your condition is right (though you should drop the == true). What is happening is that the scanner will keep going until it reaches the end of the input. Try Ctrl+D, or pipe the input from a file (java myclass < input.txt).

I really like the solution proposed by @Brian Diggs. However, in my case, I create the line plots in a loop rather than giving them explicitly because I do not know apriori how many plots I will have. When I tried to adapt the @Brian's code I faced some problems with handling the colors correctly. Turned out I needed to modify the aesthetic functions. In case someone has the same problem, here is the code that worked for me.

I used the same data frame as @Brian:

data <- structure(list(month = structure(c(1317452400, 1317538800, 1317625200, 1317711600, 
                                       1317798000, 1317884400, 1317970800, 1318057200, 
                                       1318143600, 1318230000, 1318316400, 1318402800, 
                                       1318489200, 1318575600, 1318662000, 1318748400, 
                                       1318834800, 1318921200, 1319007600, 1319094000), 
                                     class = c("POSIXct", "POSIXt"), tzone = ""),
                   TempMax = c(26.58, 27.78, 27.9, 27.44, 30.9, 30.44, 27.57, 25.71, 
                               25.98, 26.84, 33.58, 30.7, 31.3, 27.18, 26.58, 26.18, 
                               25.19, 24.19, 27.65, 23.92), 
                   TempMed = c(22.88, 22.87, 22.41, 21.63, 22.43, 22.29, 21.89, 20.52,
                                 19.71, 20.73, 23.51, 23.13, 22.95, 21.95, 21.91, 20.72, 
                                 20.45, 19.42, 19.97, 19.61), 
                   TempMin = c(19.34, 19.14, 18.34, 17.49, 16.75, 16.75, 16.88, 16.82, 
                               14.82, 16.01, 16.88, 17.55, 16.75, 17.22, 19.01, 16.95, 
                               17.55, 15.21, 14.22, 16.42)), 
              .Names = c("month", "TempMax", "TempMed", "TempMin"), 
              row.names = c(NA, 20L), class = "data.frame")  

In my case, I generate my.cols and my.names dynamically, but I don't want to make things unnecessarily complicated so I give them explicitly here. These three lines make the ordering of the legend and assigning colors easier.

my.cols <- heat.colors(3, alpha=1)
my.names <- c("TempMin", "TempMed", "TempMax")
names(my.cols) <- my.names

And here is the plot:

p <-  ggplot(data, aes(x = month))

for (i in 1:3){
  p <- p + geom_line(aes_(y = as.name(names(data[i+1])), colour = 
colnames(data[i+1])))#as.character(my.names[i])))
}
p + scale_colour_manual("", 
                        breaks = as.character(my.names),
                        values = my.cols)
p

That's only a convention. The Javascript language does not give any special meaning to identifiers starting with underscore characters.

That said, it's quite a useful convention for a language that doesn't support encapsulation out of the box. Although there is no way to prevent someone from abusing your classes' implementations, at least it does clarify your intent, and documents such behavior as being wrong in the first place.

Frustratingly the Numpy package published to PyPI won't install on most Windows computers https://github.com/numpy/numpy/issues/5479

Instead:

1. Download the Numpy wheel for your Python version from http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy
2. Install it from the command line pip install numpy-1.10.2+mkl-cp35-none-win_amd64.whl

<a onclick="jsfunction()" href="#">

or

<a onclick="jsfunction()" href="javascript:void(0);">

Edit:

The above response is really not a good solution, having learned a lot about JS since I initially posted. See EndangeredMassa's answer below for the better approach to solving this problem.

In the Storyboard, select the UITableView, and modify the property Style from Plain to Grouped.

Try this, replacing .myClassName with the actual name of the class (but keep the period at the beginning).

$('.myClassName').each(function() {
    alert( this.id );
});

So if the class is "test", you'd do $('.test').each(func....

This is the specific form of .each() that iterates over a jQuery object.

The form you were using iterates over any type of collection. So you were essentially iterating over an array of characters t,e,s,t.

Using that form of $.each(), you would need to do it like this:

$.each($('.myClassName'), function() {
    alert( this.id );
});

...which will have the same result as the example above.

SELECT last_value, increment_by from "other_schema".id_seq;

for adding a seq to a column where the schema is not public try this.

nextval('"other_schema".id_seq'::regclass)

Routes

Use them to define specific routes that aren't managed by controllers.

Controllers

Use them when you want to use traditional MVC architecture

Solution to your problem

You don't register controllers as routes unless you want a specific 'named' route for a controller action.

Rather than create a route for your controllers actions, just register your controller:

Route::controller('user');

Now your controller is registered, you can navigate to http://localhost/mysite/public/user and your get_index will be run.

You can also register all controllers in one go:

Route::controller(Controller::detect());

If the object is actually a Boolean instance, then just cast it:

boolean di = (Boolean) someObject;

The explicit cast will do the conversion to Boolean, and then there's the auto-unboxing to the primitive value. Or you can do that explicitly:

boolean di = ((Boolean) someObject).booleanValue();

If someObject doesn't refer to a Boolean value though, what do you want the code to do?

Python tells me where it lives when it gives me an error message :)

>>> import os
>>> os.environ['PYTHONPATH'].split(os.pathsep)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Users\martin\AppData\Local\Programs\Python\Python36-32\lib\os.py", line 669, in __getitem__
    raise KeyError(key) from None
KeyError: 'PYTHONPATH'
>>>

None of the above methods worked for me. If you are on Windows, try this on PyCharm terminal:

setx YOUR_VAR "VALUE"

You can access it in your scripts using os.environ['YOUR_VAR'].

// start snippet
error: function(XMLHttpRequest, textStatus, errorThrown) {
        if (XMLHttpRequest.readyState == 4) {
            // HTTP error (can be checked by XMLHttpRequest.status and XMLHttpRequest.statusText)
        }
        else if (XMLHttpRequest.readyState == 0) {
            // Network error (i.e. connection refused, access denied due to CORS, etc.)
        }
        else {
            // something weird is happening
        }
    }
//end snippet

If you don't have the .PBO file:

C#

public int GetLineNumber(Exception ex)
{
    var lineNumber = 0;
    const string lineSearch = ":line ";
    var index = ex.StackTrace.LastIndexOf(lineSearch);
    if (index != -1)
    {
        var lineNumberText = ex.StackTrace.Substring(index + lineSearch.Length);
        if (int.TryParse(lineNumberText, out lineNumber))
        {
        }
    }
    return lineNumber;
}

Vb.net

Public Function GetLineNumber(ByVal ex As Exception)
    Dim lineNumber As Int32 = 0
    Const lineSearch As String = ":line "
    Dim index = ex.StackTrace.LastIndexOf(lineSearch)
    If index <> -1 Then
        Dim lineNumberText = ex.StackTrace.Substring(index + lineSearch.Length)
        If Int32.TryParse(lineNumberText, lineNumber) Then
        End If
    End If
    Return lineNumber
End Function

Or as an extentions on the Exception class

public static class MyExtensions
{
    public static int LineNumber(this Exception ex)
    {
        var lineNumber = 0;
        const string lineSearch = ":line ";
        var index = ex.StackTrace.LastIndexOf(lineSearch);
        if (index != -1)
        {
            var lineNumberText = ex.StackTrace.Substring(index + lineSearch.Length);
            if (int.TryParse(lineNumberText, out lineNumber))
            {
            }
        }
        return lineNumber;
    }
}   

TemplateBinding is not quite the same thing. MSDN docs are often written by people that have to quiz monosyllabic SDEs about software features, so the nuances are not quite right.

TemplateBindings are evaluated at compile time against the type specified in the control template. This allows for much faster instantiation of compiled templates. Just fumble the name in a templatebinding and you'll see that the compiler will flag it.

The binding markup is resolved at runtime. While slower to execute, the binding will resolve property names that are not visible on the type declared by the template. By slower, I'll point out that its kind of relative since the binding operation takes very little of the application's cpu. If you were blasting control templates around at high speed you might notice it.

As a matter of practice use the TemplateBinding when you can but don't fear the Binding.

regexObject.test( String ) is faster than string.match( RegExp ).

The MDN site describes the format for document.cookie, and has an example regex to grab a cookie (document.cookie.replace(/(?:(?:^|.*;\s*)test2\s*\=\s*([^;]*).*$)|^.*$/, "$1");). Based on that, I'd go for this:

/^(.*;)?\s*cookie1\s*=/.test(document.cookie);

The question seems to ask for a solution which returns false when the cookie is set, but empty. In that case:

/^(.*;)?\s*cookie1\s*=\s*[^;]/.test(document.cookie);

Tests

function cookieExists(input) {return /^(.*;)?\s*cookie1\s*=/.test(input);}
function cookieExistsAndNotBlank(input) {return /^(.*;)?\s*cookie1\s*=\s*[^;]/.test(input);}
var testCases = ['cookie1=;cookie1=345534;', 'cookie1=345534;cookie1=;', 'cookie1=345534;', ' cookie1 = 345534; ', 'cookie1=;', 'cookie123=345534;', 'cookie=345534;', ''];
console.table(testCases.map(function(s){return {'Test String': s, 'cookieExists': cookieExists(s), 'cookieExistsAndNotBlank': cookieExistsAndNotBlank(s)}}));

Go to File > Preferences > Settings (or press Ctrl+,) then click the leftmost icon in the top right corner, "Open Settings (JSON)"

In the JSON settings window, add this (within the curly braces {}):

"terminal.integrated.shell.windows": "C:\\WINDOWS\\System32\\bash.exe"`

(Here you can put any other custom settings you want as well)

Checkout that path to make sure your bash.exe file is there otherwise find out where it is and point to that path instead.

Now if you open a new terminal window in VS Code, it should open with bash instead of PowerShell.

One does not imply the other. For a language to be statically typed it means that the types of all variables are known or inferred at compile time.

A strongly typed language does not allow you to use one type as another. C is a weakly typed language and is a good example of what strongly typed languages don't allow. In C you can pass a data element of the wrong type and it will not complain. In strongly typed languages you cannot.

You're setting the global git options, but the local checkout possibly has overrides set. Try setting them again with git config --local <setting> <value>. You can look at the .git/config file in your local checkout to see what local settings the checkout has defined.

The shortest in terms of lines of code i can think of is for the first question.

>>> import numpy as np
>>> p = np.array([[1,2],[3,4]])

>>> p = np.append(p, [[5,6]], 0)
>>> p = np.append(p, [[7],[8],[9]],1)

>>> p
array([[1, 2, 7],
   [3, 4, 8],
   [5, 6, 9]])

And the for the second question

    p = np.array(range(20))
>>> p.shape = (4,5)
>>> p
array([[ 0,  1,  2,  3,  4],
       [ 5,  6,  7,  8,  9],
       [10, 11, 12, 13, 14],
       [15, 16, 17, 18, 19]])
>>> n = 2
>>> p = np.append(p[:n],p[n+1:],0)
>>> p = np.append(p[...,:n],p[...,n+1:],1)
>>> p
array([[ 0,  1,  3,  4],
       [ 5,  6,  8,  9],
       [15, 16, 18, 19]])

Try

comp.requestFocusInWindow();

You can use strip() or split() to control the spaces values as in the following:

words = "   first  second   "

# Remove end spaces
def remove_end_spaces(string):
    return "".join(string.rstrip())


# Remove the first and end spaces
def remove_first_end_spaces(string):
    return "".join(string.rstrip().lstrip())


# Remove all spaces
def remove_all_spaces(string):
    return "".join(string.split())


# Show results
print(words)
print(remove_end_spaces(words))
print(remove_first_end_spaces(words))
print(remove_all_spaces(words))

Apart from other answer There are calculator provided by Youtube to check your usage. It is good to identify your usage. https://developers.google.com/youtube/v3/determine_quota_cost

type() is a better solution than isinstance(), particularly for booleans:

True and False are just keywords that mean 1 and 0 in python. Thus,

isinstance(True, int)

and

isinstance(False, int)

both return True. Both booleans are an instance of an integer. type(), however, is more clever:

type(True) == int

returns False.

For regex in Java, and I believe also in most regex engines, if you want to include the last part this will work:

.+?(abc)

For example, in this line:

I have this very nice senabctence

select all characters until "abc" and also include abc

using our regex, the result will be: I have this very nice senabc

Test this out: https://regex101.com/r/mX51ru/1

Underscore is a wildcard for something. for example 'A_%' will look for all match that Start whit 'A' and have minimum 1 extra character after that

You forgot to use setState. Example:

removePeople(e){
  var array = this.state.people;
  var index = array.indexOf(e.target.value); // Let's say it's Bob.
  delete array[index];
  this.setState({
    people: array
  })
},

But it's better to use filter because it does not mutate array. Example:

removePeople(e){
  var array = this.state.people.filter(function(item) {
    return item !== e.target.value
  });
  this.setState({
    people: array
  })
},

I had some problems with andy's code, but it gave me some great ideas. First problem was that we should pop off any jqXHR objects that successfully complete. I also had to modify the abortAll function. Here is my final working code:

$.xhrPool = [];
$.xhrPool.abortAll = function() {
            $(this).each(function(idx, jqXHR) {
                        jqXHR.abort();
                        });
};
$.ajaxSetup({
    beforeSend: function(jqXHR) {
            $.xhrPool.push(jqXHR);
            }
});
$(document).ajaxComplete(function() {
            $.xhrPool.pop();
            });

I didn't like the ajaxComplete() way of doing things. No matter how I tried to configure .ajaxSetup it did not work.

" the user is the one who select max no and min no ?" What do you mean by this line ?

You can use java function int random = Random.nextInt(n). This returns a random int in range[0, n-1]).

and you can set it in your textview using the setText() method

Here are some useful delete operations for mongodb using mongo shell

To delete particular document in collections: db.mycollection.remove( {name:"stack"} )

To delete all documents in collections: db.mycollection.remove()

To delete any particular collection : db.mycollection.drop()

to delete database : first go to that database by use mydb command and then

db.dropDatabase()

After tried all above, still can't resolved my issue yet. But got new solution for my problem.

At server where you are going to make a request, there should be a entry of your virtual host.

sudo vim /etc/hosts

and insert

192.xxx.x.xx www.domain.com

The reason if you are making request from server to itself then, to resolve your virtual host or to identify it, server would need above stuff, otherwise server won't understand your requesting(origin) host.
