First, review route inside index.php
require __DIR__.'/../vendor/autoload.php';
$app = require_once __DIR__.'/../bootstrap/app.php';
in my case the route did not work, I had to review the directories.
$insertation = "INSERT INTO contactinfo (name, email, subject, date, comments)
VALUES ('$name', '$email', '$subject', CURRENT_TIMESTAMP(), '$comments')";
You can use this Query. CURRENT_TIMESTAMP
Remember to use the parenthesis CURRENT_TIMESTAMP()
If you still get this error when sending email: "Failed to authenticate on SMTP server with username "[email protected]" using 3 possible authenticators"
You may try one of these methods:
Go to https://accounts.google.com/UnlockCaptcha, click continue and unlock your account for access through other media/sites.
Using a double quote password: "your password" <-- this one also solved my problem.
Likewise, I saw this error as a result of too little RAM. I cranked up the RAM on the VM and the error disappeared.
'default' => env('DB_CONNECTION', 'mysql'),
add this in your code
I suggest you look into getting composer
. https://getcomposer.org
Composer makes getting third-party libraries a LOT easier and using a single autoloader for all of them. It also standardizes on where all your dependencies are located, along with some automatization capabilities.
Download https://getcomposer.org/composer.phar to C:\Inetpub\wwwroot\php
Delete your C:\Inetpub\wwwroot\php\PHPMailer\
directory.
Use composer.phar
to get the phpmailer package using the command line to execute
cd C:\Inetpub\wwwroot\php
php composer.phar require phpmailer/phpmailer
After it is finished it will create a C:\Inetpub\wwwroot\php\vendor
directory along with all of the phpmailer files and generate an autoloader.
Next in your main project configuration file you need to include the autoload file.
require_once 'C:\Inetpub\wwwroot\php\vendor\autoload.php';
The vendor\autoload.php
will include the information for you to use $mail = new \PHPMailer;
Additional information on the PHPMailer package can be found at https://packagist.org/packages/phpmailer/phpmailer
In my case, my problem was environmental. Meaning, I did something wrong in my bash session. After attempting nearly everything in this thread, I opened a new bash session and everything was back to normal.
UPDATE:
Notice: This setting is not available for accounts with 2-Step Verification enabled, which mean you have to disable 2 factor authentication.
If you disable the 2-Step Verification:

Just in caser anyone ends here like me. In may case despite having enabled unsecure access to my google account, it refused to send the email throwing an SMTP ERROR: Password command failed: 534-5.7.14.
(Solution found at https://know.mailsbestfriend.com/smtp_error_password_command_failed_5345714-1194946499.shtml)
Steps:
log into your google account
Go to https://accounts.google.com/b/0/DisplayUnlockCaptcha and click continue to enable.
Setup your phpmailer as smtp with ssl:
$mail = new PHPMailer(true);
$mail->CharSet ="utf-8";
$mail->SMTPDebug = SMTP::DEBUG_SERVER; // or 0 for no debuggin at all
$mail->isSMTP();
$mail->Host = 'smtp.gmail.com';
$mail->Port = 465;
$mail->SMTPSecure = PHPMailer::ENCRYPTION_SMTPS;
$mail->SMTPAuth = true;
$mail->Username = 'yourgmailaccount';
$mail->Password = 'yourpassword';
And the other $mail object properties as needed.
Hope it helps someone!!
I had very similar problem today and solution was as it is..
$email = Array("Zaffar Saffee" => "[email protected]");
$schedule->command('cmd:mycmd')
->everyMinute()
->sendOutputTo("/home/forge/dev.mysite.com/storage/logs/cron.log")
->emailWrittenOutputTo($email);
It laravel 5.2 though...
my basic problem was , I was passing string instead of array so, error was
->emailWrittenOutputTo('[email protected]'); // string, we need an array
I also came across this problem. Google detected my Mac as a new device and blocked it. To unblock, in a web browser log in to your Google account and go to "Account Settings".
Scroll down and you'll find "Recent activities". Click just below that on "Devices".
Your device will be listed. Okay your device. SMTP started working for me after I did this and lowered the protection as mentioned above.
You should use an XOAuth2 token to connect to Gmail. No worries, Nodemailer already knows about that:
var smtpTransport = nodemailer.createTransport('SMTP', {
service: 'Gmail',
auth: {
XOAuth2: {
user: smtpConfig.user,
clientId: smtpConfig.client_id,
clientSecret: smtpConfig.client_secret,
refreshToken: smtpConfig.refresh_token,
accessToken: smtpConfig.access_token,
timeout: smtpConfig.access_timeout - Date.now()
}
}
};
You'll need to go to the Google Cloud Console to register your app. Then you need to retrieve access tokens for the accounts you wish to use. You can use passportjs for that.
Here's how it looks in my code:
var passport = require('passport'),
GoogleStrategy = require('./google_oauth2'),
config = require('../config');
passport.use('google-imap', new GoogleStrategy({
clientID: config('google.api.client_id'),
clientSecret: config('google.api.client_secret')
}, function (accessToken, refreshToken, profile, done) {
console.log(accessToken, refreshToken, profile);
done(null, {
access_token: accessToken,
refresh_token: refreshToken,
profile: profile
});
}));
exports.mount = function (app) {
app.get('/add-imap/:address?', function (req, res, next) {
passport.authorize('google-imap', {
scope: [
'https://mail.google.com/',
'https://www.googleapis.com/auth/userinfo.email'
],
callbackURL: config('web.vhost') + '/add-imap',
accessType: 'offline',
approvalPrompt: 'force',
loginHint: req.params.address
})(req, res, function () {
res.send(req.user);
});
});
};
Set IIS to forward your mail to the remote server. The specifics vary greatly depending on the version of IIS. For IIS 7.5:
[sendmail]
smtp_server=smtp.gmail.com
smtp_port=25
error_logfile=error.log
debug_logfile=debug.log
[email protected]
auth_password=gmailpassword
[email protected]
need authenticate username and password of mail then only once can successfully send mail from localhost
$mail->IsSMTP();
$mail->Host = "smtp.gmail.com";
$mail->SMTPAuth = true;
$mail->SMTPSecure = "ssl";
$mail->Username = "[email protected]";
$mail->Password = "**********";
$mail->Port = "465";
That is a working configuration.
try to replace what you have
You've got no SMTPSecure setting to define the type of authentication being used, and you're running the Host setting with the unnecessary 'ssl://' (PS -- ssl is over port 465, if you need to run it over ssl instead, see the accepted answer here. Here's the lines to add/change:
+ $mail->SMTPSecure = 'tls';
- $mail->Host = "ssl://smtp.gmail.com";
+ $mail->Host = "smtp.gmail.com";
b = email.message_from_string(a)
if b.is_multipart():
for payload in b.get_payload():
# if payload.is_multipart(): ...
print payload.get_payload()
else:
print b.get_payload()
u forgot to add proper content-type header in the response which is a must have http header when hosting on apache2
use
print "Content-type:text/html\r\n\r\n"
or
header('Content-Type: text/html');
Once had this issue, thought it reasonable to share how I resolved it;
I think the way to do that in php is to use the header function as:
header ("Location: exampleFile.php");
You could just enclose that header file in an if statement so that it redirects only when a certain condition is met, as in:
if (isset($_POST['submit'])){ header("Location: exampleFile.php") }
Hope that helps.
Try to login via the terminal using the following command:
mysql -u root -p
It will then prompt for your password. If this fails, then definitely the username or password is incorrect. If this works, then your database's password needs to be enclosed in quotes:
database_password: "0000"
this code working fine for me
$mail = new PHPMailer;
//Enable SMTP debugging.
$mail->SMTPDebug = 0;
//Set PHPMailer to use SMTP.
$mail->isSMTP();
//Set SMTP host name
$mail->Host = $hostname;
//Set this to true if SMTP host requires authentication to send email
$mail->SMTPAuth = true;
//Provide username and password
$mail->Username = $sender;
$mail->Password = $mail_password;
//If SMTP requires TLS encryption then set it
$mail->SMTPSecure = "ssl";
//Set TCP port to connect to
$mail->Port = 465;
$mail->From = $sender;
$mail->FromName = $sender_name;
$mail->addAddress($to);
$mail->isHTML(true);
$mail->Subject = $Subject;
$mail->Body = $Body;
$mail->AltBody = "This is the plain text version of the email content";
if (!$mail->send()) {
echo "Mailer Error: " . $mail->ErrorInfo;
}
else {
echo 'Mail Sent Successfully';
}
I was using just
$mail->Body = $message;
and for some sumbited forms the PHP was returning the error:
SMTP Error: data not accepted.SMTP server error: DATA END command failed Detail: This message was classified as SPAM and may not be delivered SMTP code: 550
I got it fixed adding this code after $mail->Body=$message :
$mail->MsgHTML = $message;
$mail->AltBody = $message;
The password is present in the log generated by docker run image as shown in the example below.
Additionally you can check the directory /var/jenkins_home/secrets/ Its in the file name initialAdminPassword
You can use cat /var/jenkins_home/secrets/initialAdminPassword to read it.
If you only want to check version for only one, you can do
composer show -- twig/twig
Note that only installed packages are shown by default now, and installed option is now deprecated.
My solution was to change:
'driver' => 'smtp',
to
'driver' => 'mail',
In app/config/mail
Hope that helps
You have to disable Globals
/**
* @backupGlobals disabled
*/
Well try ini_set('memory_limit', '256M');
134217728 bytes = 128 MB
Or rewrite the code to consume less memory.
Use comma separated values as below.
$email_to = 'Mary <[email protected]>, Kelly <[email protected]>';
@mail($email_to, $email_subject, $email_message, $headers);
or run a foreach for email address
//list of emails in array format and each one will see their own to email address
$arrEmail = array('Mary <[email protected]>', 'Kelly <[email protected]>');
foreach($arrEmail as $key => $email_to)
@mail($email_to, $email_subject, $email_message, $headers);
The suggested answer only works for certain versions of ruby. Some commenters suggest using ruby-dev; that didn't work for me either.
sudo apt-get install ruby-all-dev
worked for me.
If you still get
TCPDF ERROR: Unable to create output file: myfile.pdf
you can avoid TCPDF's file saving logic by putting PDF data to a variable and saving this string to a file:
$pdf_string = $pdf->Output('pseudo.pdf', 'S');
file_put_contents('./mydir/myfile.pdf', $pdf_string);
In the HTML form I have not added following line, so no attachment was going:
enctype="multipart/form-data"
After adding above line in form (as below), the attachment went perfect.
<form id="form1" name="form1" method="post" action="form_phpm_mailer.php" enctype="multipart/form-data">
If you are sure that you already resolved all merge conflicts:
rm -rf .git/MERGE*
And the error will disappear.
do like this-paste your html code inside your separate html file using GET method.
$mail->IsHTML(true);
$mail->WordWrap = 70;
$mail->addAttachment= $_GET['addattachment']; $mail->AltBody
=$_GET['AltBody']; $mail->Subject = $_GET['subject']; $mail->Body = $_GET['body'];
At least in the current versions of PHPMailers, there's a function clearReplyTos() to empty the reply-to array.
$mail->ClearReplyTos();
$mail->addReplyTo([email protected], 'EXAMPLE');
The best approach I've come up with is to use Sass imports on a selected basis to pull in your bootstrap (or any other) styles into emails as might be needed.
First, create a new scss parent file something like email.scss
for your email style. This could look like this:
// Core variables and mixins
@import "css/main/ezdia-variables";
@import "css/bootstrap/mixins";
@import "css/main/ezdia-mixins";
// Import base classes
@import "css/bootstrap/scaffolding";
@import "css/bootstrap/type";
@import "css/bootstrap/buttons";
@import "css/bootstrap/alerts";
// nest conflicting bootstrap styles
.bootstrap-style {
//use single quotes for nested imports
@import 'css/bootstrap/normalize';
@import 'css/bootstrap/tables';
}
@import "css/main/main";
// Main email classes
@import "css/email/zurb";
@import "css/email/main";
Then in your email templates, only reference your compiled email.css file, which only contains the selected bootstrap styles referenced and nested properly in your email.scss.
For example, certain bootstrap styles will conflict with Zurb's responsive table style. To fix that, you can nest bootstrap's styles within a parent class or other selector in order to call bootstrap's table styles only when needed.
This way, you have the flexibility to pull in classes only when needed. You'll see that I use http://zurb.com/
which is a great responsive email library to use. See also http://zurb.com/ink/
Lastly, use a premailer like https://github.com/fphilipe/premailer-rails3
mentioned above to process the style into inline css, compiling inline styles to only what is used in that particular email template. For instance, for premailer, your ruby file could look something like this to compile an email into inline style.
require 'rubygems' # optional for Ruby 1.9 or above.
require 'premailer'
premailer = Premailer.new('http://www.yourdomain.com/TestSnap/view/emailTemplates/DeliveryReport.jsp', :warn_level => Premailer::Warnings::SAFE)
# Write the HTML output
File.open("delivery_report.html", "w") do |fout|
fout.puts premailer.to_inline_css
end
# Write the plain-text output
File.open("output.txt", "w") do |fout|
fout.puts premailer.to_plain_text
end
# Output any CSS warnings
premailer.warnings.each do |w|
puts "#{w[:message]} (#{w[:level]}) may not render properly in #{w[:clients]}"
end
Hope this helps! Been struggling to find a flexible email templating framework across Pardot, Salesforce, and our product's built-in auto-response and daily emails.
You were setting BCC but then overwriting the variable with the FROM
$to = "[email protected]";
$subject .= "".$emailSubject."";
$headers .= "Bcc: ".$emailList."\r\n";
$headers .= "From: [email protected]\r\n" .
"X-Mailer: php";
$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n";
$message = '<html><body>';
$message .= 'THE MESSAGE FROM THE FORM';
if (mail($to, $subject, $message, $headers)) {
$sent = "Your email was sent!";
} else {
$sent = ("Error sending email.");
}
I had the same problem;
textStatus = 'error'
errorThrown = (empty)
xhr.status = 0
That fits my problem exactly. It turns out that when I was loading the HTML-page from my own computer this problem existed, but when I loaded the HTML-page from my webserver it went alright. Then I tried to upload it to another domain, and again the same error occoured. Seems to be a cross-domain problem. (in my case at least)
I have tried calling it this way also:
var request = $.ajax({
url: "http://crossdomain.url.net/somefile.php", dataType: "text",
crossDomain: true,
xhrFields: {
withCredentials: true
}
});
but without success.
This post solved it for me: jQuery AJAX cross domain
Use the serialize method:
$.ajax({
...
data: $("#registerSubmit").serialize(),
...
})
Docs: serialize()
go to config/environments/test.rb
Rails.application.routes.default_url_options[:host] = 'localhost:3000'
Under Windows only: You may try to use ini_set()
functionDocs for the SMTP
Docs and smtp_port
Docs settings:
ini_set('SMTP', 'mysmtphost');
ini_set('smtp_port', 25);
For prevent an error "can't modify frozen string" for encoding a varible you can use: var.dup.force_encoding(Encoding::ASCII_8BIT)
or var.dup.force_encoding(Encoding::UTF_8)
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.
The other post is correct to resolve the issue but doesn't address how to do it if the 2-step-verification is turned on. The option to allow the less secure apps is NOT available then. Here is an answer to how to do it:
a. Go to the URL of `https://myaccount.google.com/` and click `Sing-in and security`
b. Click on the app password.
You will reach a page like this,
c. Create name of your app and generate a password for the respective app.
d. Use that password acquired here inside the app.
This should resolve the issue.
I found the answer:
$mail->AddEmbeddedImage('img/2u_cs_mini.jpg', 'logo_2u');
and on the <img>
tag put src='cid:logo_2u'

You perhaps use the wrong username.
I had a similar error. Ensure you're not using uppercase while logging into server.
Example: [email protected]
If you use ->setUsername('JacekPL')
, this can cause an error. Use ->setUsername('jacekpl')
instead. This solved my problem.
Since some of the answers give here relate to setting up SMTP in general (and not just for @shinod particular issue where it had been working and stopped), I thought it would be helpful if I updated the answer because this is a lot simpler to do now than it used to be :-)
In PHP 4 the PEAR Mail package is typically already installed, and this really simple tutorial shows you the few lines of code that you need to add to your php file http://email.about.com/od/emailprogrammingtips/qt/PHP_Email_SMTP_Authentication.htm
Most hosting companies list the SMTP settings that you'll need. I use JustHost, and they list theirs at https://my.justhost.com/cgi/help/26 (under Outgoing Mail Server)
In your mail3.php file you should trap errors in a try {} catch {}
try {
/*code here for email*/
} catch (Exception $e) {
header('HTTP/1.1 500 Internal Server Error');
}
Then in your success
call you wont have to worry about your errors, because it will never return as a success.
and you can use: window.location.href = "thankyou.php";
inside your success function like Nick stated.
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 need to call the AddAddress
method once for every recipient. Like so:
$mail->AddAddress('[email protected]', 'Person One');
$mail->AddAddress('[email protected]', 'Person Two');
// ..
Better yet, add them as Carbon Copy recipients.
$mail->AddCC('[email protected]', 'Person One');
$mail->AddCC('[email protected]', 'Person Two');
// ..
To make things easy, you should loop through an array to do this.
$recipients = array(
'[email protected]' => 'Person One',
'[email protected]' => 'Person Two',
// ..
);
foreach($recipients as $email => $name)
{
$mail->AddCC($email, $name);
}
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

I was getting ó in $mail->Subject /w PHPMailer.
So for me the complete solution is:
// Your Subject with tildes. Example.
$someSubjectWithTildes = 'Subscripción España';
$mailer->CharSet = 'UTF-8';
$mailer->Encoding = 'quoted-printable';
$mailer->Subject = html_entity_decode($someSubjectWithTildes);
Hope it helps.
This one works fine
use try { as above
use Catch as above but comment out the echo lines
} catch (phpmailerException $e) {
//echo $e->errorMessage(); //Pretty error messages from PHPMailer
} catch (Exception $e) {
//echo $e->getMessage(); //Boring error messages from anything else!
}
Then add this
if ($e) {
//enter yor error message or redirect the user
} else {
//do something else
}
I solved this by adding email accounts in Cpanel and also adding that same email to the header from field like this
$header = 'From: XXXXXXXX <[email protected]>' . "\r\n";
This a system error.
Check error of the system with:
tail /var/log/httpd/error_log
It can be any reason.
All answers are great. Here is an example use case for multiple add address: The ability to add as many email you want on demand with a web form:
See it in action with jsfiddle here (except the php processor)
### Send unlimited email with a web form
# Form for continuously adding e-mails:
<button type="button" onclick="emailNext();">Click to Add Another Email.</button>
<div id="addEmail"></div>
<button type="submit">Send All Emails</button>
# Script function:
<script>
function emailNext() {
var nextEmail, inside_where;
nextEmail = document.createElement('input');
nextEmail.type = 'text';
nextEmail.name = 'emails[]';
nextEmail.className = 'class_for_styling';
nextEmail.style.display = 'block';
nextEmail.placeholder = 'Enter E-mail Here';
inside_where = document.getElementById('addEmail');
inside_where.appendChild(nextEmail);
return false;
}
</script>
# PHP Data Processor:
<?php
// ...
// Add the rest of your $mailer here...
if ($_POST[emails]){
foreach ($_POST[emails] AS $postEmail){
if ($postEmail){$mailer->AddAddress($postEmail);}
}
}
?>
So what it does basically is to generate a new input text box on every click with the name "emails[]".
The [] added at the end makes it an array when posted.
Then we go through each element of the array with "foreach" on PHP side adding the:
$mailer->AddAddress($postEmail);
It can be this:
If you are using cpanel for your website smtp restrictions are problem and cause this error. SMTP Restrictions
You need to make sure that your from address is a valid email account setup on that server.
Exim 4 requires that AUTH command only be sent after the client issued EHLO - attempts to authenticate without EHLO would be rejected. Some mailservers require that EHLO be issued twice. PHPMailer apparently fails to do so. If PHPMailer does not allow you to force EHLO initiation, you really should switch to SwiftMailer 4.
On CentOS 5.5, the easiest way I've found to set the default from domain is to modify the hosts file. If your hosts file contains your WAN/public IP address, simply modify the first hostname listed for it. For example, your hosts file may look like:
...
11.22.33.44 localhost default-domain whatever-else.com
...
To make it send from whatever-else.com, simply modify it so that whatever-else.com is listed first, for example:
...
11.22.33.44 whatever-else.com localhost default-domain
...
I can't speak for any other distro (or even version of CentOS) but in my particular case, the above works perfectly.

To convert a time in one timezone to another timezone in Python, you could use datetime.astimezone():
so, below code is to convert the local time to other time zone.
# Time conversion from local time
import datetime
import pytz
dt_today = datetime.datetime.today() # Local time
dt_India = dt_today.astimezone(pytz.timezone('Asia/Kolkata'))
dt_London = dt_today.astimezone(pytz.timezone('Europe/London'))
India = (dt_India.strftime('%m/%d/%Y %H:%M'))
London = (dt_London.strftime('%m/%d/%Y %H:%M'))
print("Indian standard time: "+India+" IST")
print("British Summer Time: "+London+" BST")
import pytz
for tz in pytz.all_timezones:
print(tz)
Kotlin way:
Manifest:
<application android:name="MyApplication">
</application>
MyApplication.kt
class MyApplication: Application() {
override fun onCreate() {
super.onCreate()
instance = this
}
companion object {
lateinit var instance: MyApplication
private set
}
}
You can then access the property via MyApplication.instance
There are several ways you can do that:
node_modules/@angular/core/package.json
and check version
field.If you need to use it in your code, you can import it from the @angular/core
:
import { VERSION } from '@angular/core';
Inspect the rendered DOM - Angular adds the version to the main component element:
<my-app ng-version="4.1.3">
Here is a simple function to do this for you:
def precision(num,x):
return "{0:.xf}".format(round(num))
Here, num is the decimal number. x is the decimal up to where you want to round a floating number.
The advantage over other implementation is that it can fill zeros at the right end of the decimal to make a deciaml number up to x decimal places.
Example 1:
precision(10.2, 9)
will return
10.200000000 (up to 9 decimal points)
Example 2:
precision(10.2231, 2)
will return
10.22 (up to two decimal points)
When using either a DISABLE or ENABLE TRIGGER statement in a batch that has other statements in it, the statement just before it must end with a semicolon. Otherwise, you'll get a syntax error. I tore my hair out with this one... And afterwards, I stumbled on this MS Connect item about the same thing. It is closed as won't fix.

Assuming your page is available under "http://example.com"
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
driver = webdriver.Firefox()
driver.get("http://example.com")
Select element by id:
inputElement = driver.find_element_by_id("a1")
inputElement.send_keys('1')
Now you can simulate hitting ENTER:
inputElement.send_keys(Keys.ENTER)
or if it is a form you can submit:
inputElement.submit()
I had this issue as well. In my case, I was trying to get a post-receive Git hook to update a working copy on a server with each push. Tried to follow the instructions in the blog you linked to. Didn't work for me as well and overriding the settings on a per-user basis didn't seem to work either.
What I ended up having to do was disable SSL verification (as the article mentions) for Git as a whole. Not the perfect solution, but it'll work until I can figure out a better one.
I edited the Git config text file (with my favorite line-ending neutral app like Notepad++) located at:
C:\Program Files (x86)\Git\etc\gitconfig
In the [http] block, I added an option to disable sslVerify. It looked like this when I was done:
[http]
sslVerify = false
sslCAinfo = /bin/curl-ca-bundle.crt
That did the trick.
NOTE:
This disables SSL verification and is not recommended as a long term solution.
You can disable this per-repository which still isn't great, but localizes the setting.
With the advent of LetsEncrypt.org, it is now fairly simple, automated and free to set up SSL as an alternative to self-signed certs and negates the need to turn off sslVerify.
Development Phase:
Step 1: Create Certificate .pem from Certificate .p12
openssl pkcs12 -clcerts -nokeys -out apns-dev-cert.pem -in apns-dev-cert.p12
Step 2: Create Key .pem from Key .p12
openssl pkcs12 -nocerts -out apns-dev-key.pem -in apns-dev-key.p12
Step 3 (Optional): If you want to remove pass phrase asked in second step
openssl rsa -in apns-dev-key.pem -out apns-dev-key-noenc.pem
Step 4: Now we have to merge the Key .pem and Certificate .pem to get Development .pem needed for Push Notifications in Development Phase of App.
If 3rd step was performed, run:
cat apns-dev-cert.pem apns-dev-key-noenc.pem > apns-dev.pem
If 3rd step was not performed, run:
cat apns-dev-cert.pem apns-dev-key.pem > apns-dev.pem
Step 5: Check certificate validity and connectivity to APNS
If 3rd step was performed, run:
openssl s_client -connect gateway.sandbox.push.apple.com:2195 -cert apns-dev-cert.pem -key apns-dev-key-noenc.pem
If 3rd step was not performed, run:
openssl s_client -connect gateway.sandbox.push.apple.com:2195 -cert apns-dev-cert.pem -key apns-dev-key.pem
Production Phase:
Step 1: Create Certificate .pem from Certificate .p12
openssl pkcs12 -clcerts -nokeys -out apns-pro-cert.pem -in apns-pro-cert.p12
Step 2: Create Key .pem from Key .p12
openssl pkcs12 -nocerts -out apns-pro-key.pem -in apns-pro-key.p12
Step 3 (Optional): If you want to remove pass phrase asked in second step
openssl rsa -in apns-pro-key.pem -out apns-pro-key-noenc.pem
Step 4: Now we have to merge the Key .pem and Certificate .pem to get Production .pem needed for Push Notifications in Production Phase of App.
If 3rd step was performed, run:
cat apns-pro-cert.pem apns-pro-key-noenc.pem > apns-pro.pem
If 3rd step was not performed, run:
cat apns-pro-cert.pem apns-pro-key.pem > apns-pro.pem
Step 5: Check certificate validity and connectivity to APNS.
If 3rd step was performed, run:
openssl s_client -connect gateway.push.apple.com:2195 -cert apns-pro-cert.pem -key apns-pro-key-noenc.pem
If 3rd step was not performed, run:
openssl s_client -connect gateway.push.apple.com:2195 -cert apns-pro-cert.pem -key apns-pro-key.pem
It's really simple using the forEach method since ES5+. You can directly change each property of each object in your array.
myArray.forEach(function (arrayElem){
arrayElem = newPropertyValue;
});
If you want to access a specific property on each object:
myArray.forEach(function (arrayElem){
arrayElem.nameOfYourProperty = newPropertyValue;
});
The varying line-ending characters don't matter, assuming the file is open in text mode, which is what you get unless you ask for binary. The compiled program will write out the correct thing for the system compiled for.
The only difference is that std::endl
flushes the output buffer, and '\n'
doesn't. If you don't want the buffer flushed frequently, use '\n'
. If you do (for example, if you want to get all the output, and the program is unstable), use std::endl
.
A function is just a class with a __call__
method, so you can do
hasattr(obj, '__call__')
For example:
>>> hasattr(x, '__call__')
True
>>> x = 2
>>> hasattr(x, '__call__')
False
That is the "best" way of doing it, but depending on why you need to know if it's callable or note, you could just put it in a try/execpt block:
try:
x()
except TypeError:
print "was not callable"
It's arguable if try/except is more Python'y than doing if hasattr(x, '__call__'): x()
.. I would say hasattr
is more accurate, since you wont accidently catch the wrong TypeError, for example:
>>> def x():
... raise TypeError
...
>>> hasattr(x, '__call__')
True # Correct
>>> try:
... x()
... except TypeError:
... print "x was not callable"
...
x was not callable # Wrong!
UPDATE dummy SET myfield=1 WHERE id>1;

There are no global variables in Java, but there are global classes with public fields. You can use static import feature of java 5 to make it look almost like global variables.
unset($a->new_property);
This works for array elements, variables, and object attributes.
Example:
$a = new stdClass();
$a->new_property = 'foo';
var_export($a); // -> stdClass::__set_state(array('new_property' => 'foo'))
unset($a->new_property);
var_export($a); // -> stdClass::__set_state(array())
Either use casting as others have already said, or multiply one of the int variables by 1.0
:
double firstSolution = ((1.0* b1 * a22 - b2 * a12) / (a11 * a22 - a12 * a21));
You can also just right click on the page in the browser and select "Inspect Element" to bring up the developer tools.
If the string was constructed in the same program, I would recommend using this:
String newline = System.getProperty("line.separator");
boolean hasNewline = word.contains(newline);
But if you are specced to use \n, this driver illustrates what to do:
class NewLineTest {
public static void main(String[] args) {
String hasNewline = "this has a newline\n.";
String noNewline = "this doesn't";
System.out.println(hasNewline.contains("\n"));
System.out.println(hasNewline.contains("\\n"));
System.out.println(noNewline.contains("\n"));
System.out.println(noNewline.contains("\\n"));
}
}
Resulted in
true
false
false
false
In reponse to your comment:
class NewLineTest {
public static void main(String[] args) {
String word = "test\n.";
System.out.println(word.length());
System.out.println(word);
word = word.replace("\n","\n ");
System.out.println(word.length());
System.out.println(word);
}
}
Results in
6
test
.
7
test
.
Just use the already built-in Contains() method:
using System.Linq;
//...
string[] array = { "foo", "bar" };
if (array.Contains("foo")) {
//...
}
Window.Show will show the window, and continue execution -- it's a non-blocking call.
Window.ShowDialog will block the calling thread (kinda [1]), and show the dialog. It will also block interaction with the parent/owning window. When the dialog is dismissed (for whatever reason), ShowDialog will return to the caller, and will allow you to access DialogResult (if you want it).
[1] It will keep the dispatcher pumping by pushing a dispatcher frame onto the WPF dispatcher. This will cause the message pump to keep pumping.

Set rng = Range(Selection.Address)
If you want a loop to execute while a condition is true, and not for a certain number of iterations, it is much easier for someone else to understand:
while (cond_true)
than something like this:
for (; cond_true ; )
I know this is an older question, but I figure a useful answer never hurts. I was having issues with my encoding between a desktop application, SQLite, and GET/POST variables. Some would be in UTF-8, some would be in ASCII, and basically everything would get screwed up when foreign characters got involved.
Here is my solution. It scrubs your GET/POST/REQUEST (I omitted cookies, but you could add them if desired) on each page load before processing. It works well in a header. PHP will throw warnings if it can't detect the source encoding automatically, so these warnings are suppressed with @'s.
//Convert everything in our vars to UTF-8 for playing nice with the database...
//Use some auto detection here to help us not double-encode...
//Suppress possible warnings with @'s for when encoding cannot be detected
try
{
$process = array(&$_GET, &$_POST, &$_REQUEST);
while (list($key, $val) = each($process)) {
foreach ($val as $k => $v) {
unset($process[$key][$k]);
if (is_array($v)) {
$process[$key][@mb_convert_encoding($k,'UTF-8','auto')] = $v;
$process[] = &$process[$key][@mb_convert_encoding($k,'UTF-8','auto')];
} else {
$process[$key][@mb_convert_encoding($k,'UTF-8','auto')] = @mb_convert_encoding($v,'UTF-8','auto');
}
}
}
unset($process);
}

Have a look at the official issue 33930. There is pointed out, that it may have to do with the start up of OpenGL during the start of the emulator. Others wrote it only crashes when they use WXGA800-skin and suggest to manually set the resolution to 800x1280.
Further there are ZIP-files provided to manually downgrade your android SDK to version 19 and plattform-tools to version 11. This may help as well to temporally fix the issue.
If you don't know (or care) how many arguments you will be passing to the function, you could also use a very simple approach like;
Code:
function FunctionName()
{
Write-Host $args
}
That would print out all arguments. For example:
FunctionName a b c 1 2 3
Output
a b c 1 2 3
I find this particularly useful when creating functions that use external commands that could have many different (and optional) parameters, but relies on said command to provide feedback on syntax errors, etc.
Here is a another real-world example (creating a function to the tracert command, which I hate having to remember the truncated name);
Code:
Function traceroute
{
Start-Process -FilePath "$env:systemroot\system32\tracert.exe" -ArgumentList $args -NoNewWindow
}
I don't think you can do this with the standard tools. You can use ipcs -mp
to get the process ID of the last process to attach/detach but I'm not aware of how to get all attached processes with ipcs
.
With a two-process-attached segment, assuming they both stayed attached, you can possibly figure out from the creator PID cpid
and last-attached PID lpid
which are the two processes but that won't scale to more than two processes so its usefulness is limited.
The cat /proc/sysvipc/shm
method seems similarly limited but I believe there's a way to do it with other parts of the /proc
filesystem, as shown below:
When I do a grep
on the procfs
maps for all processes, I get entries containing lines for the cpid
and lpid
processes.
For example, I get the following shared memory segment from ipcs -m
:
------ Shared Memory Segments --------
key shmid owner perms bytes nattch status
0x00000000 123456 pax 600 1024 2 dest
and, from ipcs -mp
, the cpid
is 3956 and the lpid
is 9999 for that given shared memory segment (123456).
Then, with the command grep 123456 /proc/*/maps
, I see:
/proc/3956/maps: blah blah blah 123456 /SYSV000000 (deleted)
/proc/9999/maps: blah blah blah 123456 /SYSV000000 (deleted)
So there is a way to get the processes that attached to it. I'm pretty certain that the dest
status and (deleted)
indicator are because the creator has marked the segment for destruction once the final detach occurs, not that it's already been destroyed.
So, by scanning of the /proc/*/maps
"files", you should be able to discover which PIDs are currently attached to a given segment.
You could use CONCAT, and the numeric argument of it is converted to its equivalent binary string form.
select t2.*
from t1 join t2
on t2.url=CONCAT('site.com/path/%', t1.id, '%/more') where t1.id > 9000
According to VBA help on SET statement it sets a reference to an object.so if you change a property the actual object will also changes.
Dim newObj as Object
Set var1=Object1(same type as Object)
Set var2=Object1(same type as Object)
Set var3=Object1(same type as Object)
Set var4=Object1(same type as Object)
Var1.property1=NewPropertyValue
the other Vars properties also changes,so:
Var1.property1=Var2.property1=Var3.property1=Var4.property1=Object1.Property1=NewpropertyValue`
actualy all vars are the same!
Came up with a quick and dirty fix to this. Just used <select onchange='this.options[this.selectedIndex].onclick();> <option onclick='alert("hello world")' ></option> </select>
Hope this helps

To add a bit more value to all the other answer's to this question, one should invest a few minutes in the question: What is the output of the following code?
#include <iostream>
void throw_exception() throw(const char *)
{
throw 10;
}
void my_unexpected(){
std::cout << "well - this was unexpected" << std::endl;
}
int main(int argc, char **argv){
std::set_unexpected(my_unexpected);
try{
throw_exception();
}catch(int x){
std::cout << "catch int: " << x << std::endl;
}catch(...){
std::cout << "catch ..." << std::endl;
}
}
Answer: As noted here, the program calls std::terminate()
and thus none of the exception handlers will get called.
Details: First my_unexpected()
function is called, but since it doesn't re-throw a matching exception type for the throw_exception()
function prototype, in the end, std::terminate()
is called. So the full output looks like this:
user@user:~/tmp$ g++ -o except.test except.test.cpp
user@user:~/tmp$ ./except.test
well - this was unexpected
terminate called after throwing an instance of 'int'
Aborted (core dumped)

You can't. bash only does integers; you must delegate to a tool such as bc
.
First thing first, button()
is a jQuery ui function to create a button widget which has nothing to do with jQuery core, it just styles the button.
So if you want to use the widget add jQuery ui's javascript and CSS files or alternatively remove it, like this:
$("#filter").click(function(){
alert('clicked!');
});
Another thing that might have caused you the problem is if you didn't wait for the input to be rendered and wrote the code before the input. jQuery has the ready function, or it's alias $(func)
which execute the callback once the DOM is ready.
Usage:
$(function(){
$("#filter").click(function(){
alert('clicked!');
});
});
So even if the order is this it will work:
$(function(){
$("#filter").click(function(){
alert('clicked!');
});
});
<input type="button" id="filter" name="filter" value="Filter" />
SELECT DISTINCT a,b,c FROM t
is roughly equivalent to:
SELECT a,b,c FROM t GROUP BY a,b,c
It's a good idea to get used to the GROUP BY syntax, as it's more powerful.
For your query, I'd do it like this:
UPDATE sales
SET status='ACTIVE'
WHERE id IN
(
SELECT id
FROM sales S
INNER JOIN
(
SELECT saleprice, saledate
FROM sales
GROUP BY saleprice, saledate
HAVING COUNT(*) = 1
) T
ON S.saleprice=T.saleprice AND s.saledate=T.saledate
)
OpenSSH cannot use PKCS#12 files out of the box. As others suggested, you must extract the private key in PEM format which gets you from the land of OpenSSL to OpenSSH. Other solutions mentioned here don’t work for me. I use OS X 10.9 Mavericks (10.9.3 at the moment) with “prepackaged” utilities (OpenSSL 0.9.8y, OpenSSH 6.2p2).
First, extract a private key in PEM format which will be used directly by OpenSSH:
openssl pkcs12 -in filename.p12 -clcerts -nodes -nocerts | openssl rsa > ~/.ssh/id_rsa
I strongly suggest to encrypt the private key with password:
openssl pkcs12 -in filename.p12 -clcerts -nodes -nocerts | openssl rsa -passout 'pass:Passw0rd!' > ~/.ssh/id_rsa
Obviously, writing a plain-text password on command-line is not safe either, so you should delete the last command from history or just make sure it doesn’t get there. Different shells have different ways. You can prefix your command with space to prevent it from being saved to history in Bash and many other shells. Here is also how to delete the command from history in Bash:
history -d $(history | tail -n 2 | awk 'NR == 1 { print $1 }')
Alternatively, you can use different way to pass a private key password to OpenSSL - consult OpenSSL documentation for pass phrase arguments.
Then, create an OpenSSH public key which can be added to authorized_keys file:
ssh-keygen -y -f ~/.ssh/id_rsa > ~/.ssh/id_rsa.pub
You may try this way. just use a function to get your object
def get_object(self, id):
try:
return UniversityDetails.objects.get(email__exact=email)
except UniversityDetails.DoesNotExist:
return False
Corresponding to INSERT (Transact-SQL) (SQL Server 2005) you can't omit INSERT INTO dbo.Blah
and have to specify it every time or use another syntax/approach,
To avoid throw a exception while "p" or "p.User" is None, you can use:
{{ (p and p.User and p.User['first_name']) or "default_value" }}
I agree with other answers that you are doing something weird here. You have a list containing a string with multiple entries that are themselves integers that you are comparing to an integer id.
This is almost surely not what you should be doing. You probably should be taking input and converting it to integers before storing in your list. You could do that with:
input = '350882 348521 350166\r\n'
list.append([int(x) for x in input.split()])
Then your test will pass. If you really are sure you don't want to do what you're currently doing, the following should do what you want, which is to not add the new id that already exists:
list = ['350882 348521 350166\r\n']
id = 348521
if id not in [int(y) for x in list for y in x.split()]:
list.append(id)
print list
Because apt-cache policy
will list all the matches available, even if not installed, I would suggest using this command for a more manageable shortlist of GTK-related packages installed on your system:
apt list --installed libgtk*
function test(string) {
return ! string.match(/abc|def/);
}
alter table table_name rename column oldColumn to newColumn;
in most cases the List<String>
should be enough. No need to create an ArrayList
import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
...
String[] words={"ace","boom","crew","dog","eon"};
List<String> l = Arrays.<String>asList(words);
// if List<String> isnt specific enough:
ArrayList<String> al = new ArrayList<String>(l);
This work for me!
$(document).ready(function() {
$(document).on("click", "#tableId tbody tr", function() {
//some think
});
});
I suggest that you should not do it like this.
Action methods should be designed to be easily unit-tested. In this case, you should not access data directly from the request, because if you do it like this, when you want to unit test this code you have to construct a HttpRequestMessage
.
You should do it like this to let MVC do all the model binding for you:
[HttpPost]
public void Confirmation(YOURDTO yourobj)//assume that you define YOURDTO elsewhere
{
//your logic to process input parameters.
}
In case you do want to access the request. You just access the Request property of the controller (not through parameters). Like this:
[HttpPost]
public void Confirmation()
{
var content = Request.Content.ReadAsStringAsync().Result;
}
In MVC, the Request property is actually a wrapper around .NET HttpRequest and inherit from a base class. When you need to unit test, you could also mock this object.
Include in the GROUP BY
clause all SELECT
expressions that are not group function arguments.
I know this is an old post but since it comes up in a google search I thought I'd share some knowledge here. @erin-geyer pointed out that mixing migrations and seeders can create headaches and @justamartin countered that sometimes you want/need data to be populated as part of your deployment.
I'd go one step further and say that sometimes it is desirable to be able to roll out data changes consistently so that you can for example deploy to staging, see that all is well, and then deploy to production with confidence of the same results (and not have to remember to run some manual step).
However, there is still value in separating out the seed and the migration as those are two related but distinct concerns. Our team has compromised by creating migrations which call seeders. This looks like:
public function up()
{
Artisan::call( 'db:seed', [
'--class' => 'SomeSeeder',
'--force' => true ]
);
}
This allows you to execute a seed one time just like a migration. You can also implement logic that prevents or augments behavior. For example:
public function up()
{
if ( SomeModel::count() < 10 )
{
Artisan::call( 'db:seed', [
'--class' => 'SomeSeeder',
'--force' => true ]
);
}
}
This would obviously conditionally execute your seeder if there are less than 10 SomeModels. This is useful if you want to include the seeder as a standard seeder that executed when you call artisan db:seed
as well as when you migrate so that you don't "double up". You may also create a reverse seeder so that rollbacks works as expected, e.g.
public function down()
{
Artisan::call( 'db:seed', [
'--class' => 'ReverseSomeSeeder',
'--force' => true ]
);
}
The second parameter --force
is required to enable to seeder to run in a production environment.
Per JamieL's answer to another post:
Since Express.js 3x the response object has a json() method which sets all the headers correctly for you.
Example:
res.json({"foo": "bar"});
you should try the new Java Executor Services. http://docs.oracle.com/javase/6/docs/api/java/util/concurrent/ExecutorService.html
With this you don't need to program the loop the time measuring by yourself.

final ExecutorService service = Executors.newSingleThreadExecutor();

Here is the solution with a for
loop. Importantly, it takes the one call to readLines
out of the for loop so that it is not improperly called again and again. Here it is:
fileName <- "up_down.txt"
conn <- file(fileName,open="r")
linn <-readLines(conn)
for (i in 1:length(linn)){
print(linn[i])
}
close(conn)
Create an object holding following properties with an appropriate name.
and use this as a value in your map.
Also consider overriding the equals() and hashCode() method accordingly if you do not want object equality to be used for comparison (e.g. when inserting values into your map).
Calling .html()
serializes the element to a string, so all event handlers and other associated data is lost. Here's how I'd do it:
$("#myButton").click(function ()
{
var test = $('<button/>',
{
text: 'Test',
click: function () { alert('hi'); }
});
var parent = $('<tr><td></td></tr>').children().append(test).end();
$("#addNodeTable tr:last").before(parent);
});
Or,
$("#myButton").click(function ()
{
var test = $('<button/>',
{
text: 'Test',
click: function () { alert('hi'); }
}).wrap('<tr><td></td></tr>').closest('tr');
$("#addNodeTable tr:last").before(test);
});
If you don't like passing a map of properties to $()
, you can instead use
$('<button/>')
.text('Test')
.click(function () { alert('hi'); });
// or
$('<button>Test</button>').click(function () { alert('hi'); });
You can use CSS gradient - although there are not consistent across browsers so You would have to code it for every one
Like that: CSS3 Transparency + Gradient
Gradient should be more transparent on top or on top right corner (depending on capabilities)
Add a column for example 'Selected' First. Then Filter your data. Go to the column 'Selected'. Provide any proxy text or number to all rows. like '1' or 'A' - now your hidden Rows are Blank Now, Clear Filter and Use Sorting - two levels Sort by - 'Selected' Ascending - this leaves blank cells at bottom Add Sort Level - 'Any column you Desire' your order
Now, Why dont you drag the autofill yourself.
Oops, I have no reputation here.
Use float() in place of int() so that your program can handle decimal points. Also, don't use next
as it's a built-in Python function, next().
Also you code as posted is missing import sys
and the definition for dead
You probably had using namespace std;
before in your code you did in class. That explicitly tells the precompiler to look for the symbols in std
, which means you don't need to std::
. Though it is good practice to std::cout
instead of cout
so you explicitly invoke std::cout
every time. That way if you are using another library that redefines cout
, you still have the std::cout
behavior instead of some other custom behavior.
I had the same issue with my app by iPads (armv7, armv7s, amr64) only by presenting another UIViewController and after dismiss them goes nav bar under status bar... I spend a lot of time to find any solution for that. I'm using storyboard and in InterfaceBuilder for UIViewController which makes terrible i set Presentation from FullScreen -> Current Context and it fix this issue. It works in my app only for iPads => iOS8.0 (testing with iOS8.1) and for iPads with iOS 7.1 not work!!
Three options:
script
is the last tag of the body, the DOM would be ready before script tag executesonreadystatechange
document.onreadystatechange = function () {
if (document.readyState == "complete") {
// document is ready. Do your stuff here
}
}
Source: MDN
DOMContentLoaded
document.addEventListener('DOMContentLoaded', function() {
console.log('document is ready. I can sleep now');
});
Concerned about stone age browsers:
Go to the jQuery source code and use the ready
function. In that case you are not parsing+executing the whole library you're are doing only a very small part of it.
Most of these answers assume the input contains a space - not whitespace, and a single space at that. If you can safely make that assumption, then the accepted answer (from bennett) is quite elegant and also the method I'll be going with when I can.
When we can't make that assumption, a more robust solution needs to cover the following siutations that most answers here don't consider:
\n
) and Windows (\r\n
) newline charactersTo cover these cases this solution uses regex to convert all whitespace (including recurring and Windows newline characters) to a single space, trims, then splits by a single space:
Swift 3:
let searchInput = " First \r\n \n \t\t\tMiddle Last "
let searchTerms = searchInput
.replacingOccurrences(
of: "\\s+",
with: " ",
options: .regularExpression
)
.trimmingCharacters(in: .whitespaces)
.components(separatedBy: " ")
// searchTerms == ["First", "Middle", "Last"]
$dateValue = '2012-01-05';
$year = date('Y',strtotime($dateValue));
$month = date('F',strtotime($dateValue));
Use SSIS to extract and process the information. That way you will have the processing of the XML files separated from SQL Server. You can also do the SSIS transformations on a separate server if needed. Store the phone numbers in a standard format using VARCHAR. NVARCHAR would be unnecessary since we are talking about numbers and maybe a couple of other chars, like '+', ' ', '(', ')' and '-'.
Rename file extensions for all files under current directory and sub directories without any other packages (only use shell script):
Create a shell script rename.sh
under current directory with the following code:
#!/bin/bash
for file in $(find . -name "*$1"); do
mv "$file" "${file%$1}$2"
done
Run it by ./rename.sh .old .new
.
Eg. ./rename.sh .html .txt
The difference is that the post-increment operator i++
returns i
as it was before incrementing, and the pre-increment operator ++i
returns i
as it is after incrementing. If you're asking about a typical for
loop:
for (i = 0; i < 10; i++)
or
for (i = 0; i < 10; ++i)
They're exactly the same, since you're not using i++
or ++i
as a part of a larger expression.
I had the same problem on my mac, but in my case, the problem was that I did not run the database (sudo mongod) before; the problem was solved when I first ran the mondo sudod on the console and, once it was done, on another console, the connection to the server ...
if (chapeau) {
You forgot the ending brace to this if
statement, so the subsequent else if
is considered a syntax error. You need to add the brace when the if
statement body is complete:
if (chapeau) {
cout << "le Professeur Violet";
}
else if (moustaches) {
cout << "le Colonel Moutarde";
}

Mads Hansen's solution is good but to succeed in reading the external file in .NET 4 took some time to figure out using hints in the comments about resolvers, ProhibitDTD and so on.
This is how it's done:
XmlReaderSettings settings = new XmlReaderSettings();
settings.DtdProcessing = DtdProcessing.Parse;
XmlUrlResolver resolver = new XmlUrlResolver();
resolver.Credentials = System.Net.CredentialCache.DefaultCredentials;
settings.XmlResolver = resolver;
var reader = XmlReader.Create("logfile.xml", settings);
XmlDocument doc = new XmlDocument();
doc.Load(reader);
foreach (XmlElement element in doc.SelectNodes("//event"))
{
var ch = element.ChildNodes;
var count = ch.Count;
}
logfile.xml:
<?xml version="1.0"?>
<!DOCTYPE logfile [
<!ENTITY events
SYSTEM "events.txt">
]>
<logfile>
&events;
</logfile>
events.txt:

<item1>item1</item1>
<item2>item2</item2>

Convert dates to Java 8 java.time.LocalDate as seen here.
LocalDate localDate1 = date1.toInstant().atZone(ZoneId.systemDefault()).toLocalDate();
LocalDate localDate2 = date2.toInstant().atZone(ZoneId.systemDefault()).toLocalDate();
// compare dates
assertTrue("Not on the same day", localDate1.equals(localDate2));
It's important to point out that all of the above solutions map the port to every interface on your machine. This is less than desirable if you have a public IP address, or your machine has an IP on a large network. Your application may be exposed to a much wider audience than you'd hoped.
redis:
build:
context:
dockerfile: Dockerfile-redis
ports:
- "127.0.0.1:3901:3901"
127.0.0.1
is the ip address that maps to the hostname localhost
on your machine. So now your application is only exposed over that interface and since 127.0.0.1
is only accessible via your machine, you're not exposing your containers to the entire world.
The documentation explains this further and can be found here: https://docs.docker.com/compose/compose-file/#ports
Note: If you're using Docker for mac this will make the container listen on 127.0.0.1 on the Docker for Mac VM and will not be accessible from your localhost. If I recall correctly.
If you want to trim the whitespace off just the beginning and end of the string, you can do something like this:
some_string = " Hello, world!\n "
new_string = some_string.strip()
# new_string is now "Hello, world!"
This works a lot like Qt's QString::trimmed() method, in that it removes leading and trailing whitespace, while leaving internal whitespace alone.
But if you'd like something like Qt's QString::simplified() method which not only removes leading and trailing whitespace, but also "squishes" all consecutive internal whitespace to one space character, you can use a combination of .split()
and " ".join
, like this:
some_string = "\t Hello, \n\t world!\n "
new_string = " ".join(some_string.split())
# new_string is now "Hello, world!"
In this last example, each sequence of internal whitespace replaced with a single space, while still trimming the whitespace off the start and end of the string.
I'd use standard javascript:
for (var m in myMap){
for (var i=0;i<myMap[m].length;i++){
... do something with myMap[m][i] ...
}
}
Note the different ways of treating objects and arrays.
You can define your escape character, but you can only use it with a LIKE
clause.
Example:
SELECT columns FROM table
WHERE column LIKE '%\%%' ESCAPE '\'
Here it will search for %
in whole string and this is how one can use ESCAPE
identifier in SQL Server
.
Also do note when specifying DATETIME
as DATETIME(3)
or like on MySQL 5.7.x, you also have to add the same value for CURRENT_TIMESTAMP(3)
. If not it will keep throwing 'Invalid default value'.
I think you're confused by different paradigms here. First, war files and server deployment -- those things belong to Java Enterprise Edition (Java EE). These concepts have no real place in a spring-boot application, which follows a different model.
Spring-boot is responsible for creating an embedded container and running your services within it directly from standard jar files (although it can do a lot more). I think the intent of this model is to support micro-service development -- where each service has its own container and is completely self contained. You can use your code to generate Java EE apps too, but that would be silly considering that spring-boot is a lot easier (for certain types of application/service).
So, given this information you now have to decide what paradigm you're going to follow, and you need to follow that and only that.
Spring-boot is executable -- you just have to run the main method in the App class which you can do from the command line or using your favourite IDE or maven or gradle (tip: maven is the right answer). This will bring up a tomcat server (by default) and your service will be available within it. Given the configuration you posted above your service should be available at: http://localhost:7777/context/help
-- the context
is meant to be replaced with your context name, which you haven't shared.
You aren't meant to be creating a war, running tomcat, or deploying anything. None of that is necessary in spring-boot. The packaging in your pom should be jar
, not war
and the scope
of the spring-boot-starter-tomcat
should be removed -- it certainly isn't provided.
When you run your main method, the console output should tell you the context that you've registered; use that to get the URL right.
Having said all that, spring-boot has to exist in a JEE world for now (until it is widely adopted). For that reason, the spring people have documented an approach to building a war rather than an executable jar, for deployment to a servlet or JEE container. This allows a lot of the spring-boot tech to be used in environments where there are restrictions against using anything but wars (or ears). However, this is a just a response to the fact that such environments are quite common, and is not seen as a necessary, or even desirable, part of the solution.

Once I changed Options -Index

First of all, the .json
attribute is a property that delegates to the request.get_json()
method, which documents why you see None
here.
You need to set the request content type to application/json
for the .json
property and .get_json()
method (with no arguments) to work as either will produce None
otherwise. See the Flask Request
documentation:
This will contain the parsed JSON data if the mimetype indicates JSON (application/json, see
is_json()
), otherwise it will beNone
.
You can tell request.get_json()
to skip the content type requirement by passing it the force=True
keyword argument.
Note that if an exception is raised at this point (possibly resulting in a 400 Bad Request response), your JSON data is invalid. It is in some way malformed; you may want to check it with a JSON validator.
You indicated that you're using Angular 1.2.0... as one of the other comments indicated, ng-bind-html-unsafe
has been deprecated.
Instead, you'll want to do something like this:
<div ng-bind-html="preview_data.preview.embed.htmlSafe"></div>
In your controller, inject the $sce
service, and mark the HTML as "trusted":
myApp.controller('myCtrl', ['$scope', '$sce', function($scope, $sce) {
// ...
$scope.preview_data.preview.embed.htmlSafe =
$sce.trustAsHtml(preview_data.preview.embed.html);
}
Note that you'll want to be using 1.2.0-rc3 or newer. (They fixed a bug in rc3 that prevented "watchers" from working properly on trusted HTML.)
The number is held in an int[]
- the maximum size of an array is Integer.MAX_VALUE
. So the maximum BigInteger probably is (2 ^ 32) ^ Integer.MAX_VALUE
.
Admittedly, this is implementation dependent, not part of the specification.
In Java 8, some information was added to the BigInteger javadoc, giving a minimum supported range and the actual limit of the current implementation:
BigInteger
must support values in the range-2
Integer.MAX_VALUE
(exclusive) to+2
Integer.MAX_VALUE
(exclusive) and may support values outside of that range.Implementation note:
BigInteger
constructors and operations throwArithmeticException
when the result is out of the supported range of-2
Integer.MAX_VALUE
(exclusive) to+2
Integer.MAX_VALUE
(exclusive).
Javascript which runs on the client machine can't access the local disk file system due to security restrictions.
If you want to access the client's disk file system then look into an embedded client application which you serve up from your webpage, like an Applet, Silverlight or something like that. If you like to access the server's disk file system, then look for the solution in the server side corner using a server side programming language like Java, PHP, etc, whatever your webserver is currently using/supporting.

You could always use ADO to write the results out to the worksheet cells from a recordset object
Spring Boot allows you to use a simple script to initialize your database, using Spring Batch.
Still, if you want to use something a bit more elaborated to manage DB versions and so on, Spring Boot integrates well with Flyway.
See also:
If it's possible, you can build the position array using find function, and then sort the array.
Or maybe you can use a map where the key would be the element, and the values a list of its position in the upcoming arrays (A, B and C)
It depends on later uses of those arrays.
Use ALT + CTRL + O. It will organize all the imports. You can find various other options in the "Code" Menu.

This code will list out all the form variables that are being sent in a POST. This way you can see if you have the proper names of the post values.
string[] keys = Request.Form.AllKeys;
for (int i= 0; i < keys.Length; i++)
{
Response.Write(keys[i] + ": " + Request.Form[keys[i]] + "<br>");
}
I had the same problem
I fixed that by using two options
contentType: false
processData: false
Actually I Added these two command to my $.ajax({}) function
You can also do this to set a header for all future gets for the Session object, where x-test will be in all s.get() calls:
s = requests.Session()
s.auth = ('user', 'pass')
s.headers.update({'x-test': 'true'})
# both 'x-test' and 'x-test2' are sent
s.get('http://httpbin.org/headers', headers={'x-test2': 'true'})
from: http://docs.python-requests.org/en/latest/user/advanced/#session-objects
This work on all browser to get pasted value. And also to creating common method for all text box.
$("#textareaid").bind("paste", function(e){
var pastedData = e.target.value;
alert(pastedData);
} )
To follow up, I just ran into this as well. When I installed Node.js there was an option that said Add to PATH (Available After Restart). Seems like Windows just needs a restart to make things work.

There are five ways to convert The First Way :
String str = " 123" ;
int i = Integer.parse(str);
output : 123
The second way :
String str = "hello123world";
int i = Integer.parse(str.replaceAll("[\\D]" , "" ) );
output : 123
The Third Way :
String str"123";
int i = new Integer(str);
output "123
The Fourth Way :
String str"123";
int i = Integer.valueOf(Str);
output "123
The Fifth Way :
String str"123";
int i = Integer.decode(str);
output "123

An array is a structure with a certain size. You can use dynamic arrays in vba that you can shrink or grow using ReDim but you can't remove elements in the middle. It's not clear from your sample how your array functionally works or how you determine the index position (eachHdr) but you basically have 3 options
(A) Write a custom 'delete' function for your array like (untested)
Public Sub DeleteElementAt(Byval index As Integer, Byref prLst as Variant)
Dim i As Integer
' Move all element back one position
For i = index + 1 To UBound(prLst)
prLst(i - 1) = prLst(i)
Next
' Shrink the array by one, removing the last one
ReDim Preserve prLst(Len(prLst) - 1)
End Sub
(B) Simply set a 'dummy' value as the value instead of actually deleting the element
If prLst(eachHdr) = "0" Then
prLst(eachHdr) = "n/a"
End If
(C) Stop using an array and change it into a VBA.Collection. A collection is a (unique)key/value pair structure where you can freely add or delete elements from
Dim prLst As New Collection

Classic example "Index in Books"
Consider a "Book" of 1000 pages, divided by 10 Chapters, each section with 100 pages.
Simple, huh?
Now, imagine you want to find a particular Chapter that contains a word "Alchemist". Without an index page, you have no other option than scanning through the entire book/Chapters. i.e: 1000 pages.
This analogy is known as "Full Table Scan" in database world.
But with an index page, you know where to go! And more, to lookup any particular Chapter that matters, you just need to look over the index page, again and again, every time. After finding the matching index you can efficiently jump to that chapter by skipping the rest.
But then, in addition to actual 1000 pages, you will need another ~10 pages to show the indices, so totally 1010 pages.
Thus, the index is a separate section that stores values of indexed column + pointer to the indexed row in a sorted order for efficient look-ups.
Things are simple in schools, isn't it? :P
Try:-
Dim objShell
Set objShell = WScript.CreateObject( "WScript.Shell" )
objShell.Run("""c:\Program Files\Mozilla Firefox\firefox.exe""")
Set objShell = Nothing
Note the extra ""s in the string. Since the path to the exe contains spaces it needs to be contained with in quotes. (In this case simply using "firefox.exe" would work).
Also bear in mind that many programs exist in the c:\Program Files (x86) folder on 64 bit versions of Windows.
I've used the following approach successfully in all major browsers including Chrome:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="content-type" content="text/html;charset=UTF-8" />
<title>Paginated HTML</title>
<style type="text/css" media="print">
div.page
{
page-break-after: always;
page-break-inside: avoid;
}
</style>
</head>
<body>
<div class="page">
<h1>This is Page 1</h1>
</div>
<div class="page">
<h1>This is Page 2</h1>
</div>
<div class="page">
<h1>This is Page 3</h1>
</div>
</body>
</html>
This is a simplified example. In the real code, each page div contains many more elements.
Most problems can be solved using (i) just locks, (ii) just semaphores, ..., or (iii) a combination of both! As you may have discovered, they're very similar: both prevent race conditions, both have acquire()
/release()
operations, both cause zero or more threads to become blocked/suspected...
Really, the crucial difference lies solely on how they lock and unlock.
For both locks/semaphores, trying to call acquire()
while the primitive is in state 0 causes the invoking thread to be suspended. For locks - attempts to acquire the lock is in state 1 are successful. For semaphores - attempts to acquire the lock in states {1, 2, 3, ...} are successful.
For locks in state state 0, if same thread that had previously called acquire()
, now calls release, then the release is successful. If a different thread tried this -- it is down to the implementation/library as to what happens (usually the attempt ignored or an error is thrown). For semaphores in state 0, any thread can call release and it will be successful (regardless of which thread previous used acquire to put the semaphore in state 0).
From the preceding discussion, we can see that locks have a notion of an owner (the sole thread that can call release is the owner), whereas semaphores do not have an owner (any thread can call release on a semaphore).
What causes a lot of confusion is that, in practice they are many variations of this high-level definition.
Important variations to consider:
acquire()
/release()
be called? -- [Varies massively]These depends on your book / lecturer / language / library / environment.
Here's a quick tour noting how some languages answer these details.
pthread_mutex_t
. By default, they can't be shared with any other processes (PTHREAD_PROCESS_PRIVATE
), however mutex's have an attribute called pshared. When set, so the mutex is shared between processes (PTHREAD_PROCESS_SHARED
). sem_t
. Similar to mutexes, semaphores can be shared between threasds of many processes or kept private to the threads of one single process. This depends on the pshared argument provided to sem_init
. threading.RLock
) is mostly the same as C/C++ pthread_mutex_t
s. Both are both reentrant. This means they may only be unlocked by the same thread that locked it. It is the case that sem_t
semaphores, threading.Semaphore
semaphores and theading.Lock
locks are not reentrant -- for it is the case any thread can perform unlock the lock / down the semaphore.threading.Semaphore
) is mostly the same as sem_t
. Although with sem_t
, a queue of thread ids is used to remember the order in which threads became blocked when attempting to lock it while it is locked. When a thread unlocks a semaphore, the first thread in the queue (if there is one) is chosen to be the new owner. The thread identifier is taken off the queue and the semaphore becomes locked again. However, with threading.Semaphore
, a set is used instead of a queue, so the order in which threads became blocked is not stored -- any thread in the set may be chosen to be the next owner.java.util.concurrent.ReentrantLock
) is mostly the same as C/C++ pthread_mutex_t
's, and Python's threading.RLock
in that it also implements a reentrant lock. Sharing locks between processes is harder in Java because of the JVM acting as an intermediary. If a thread tries to unlock a lock it doesn't own, an IllegalMonitorStateException
is thrown.java.util.concurrent.Semaphore
) is mostly the same as sem_t
and threading.Semaphore
. The constructor for Java semaphores accept a fairness boolean parameter that control whether to use a set (false) or a queue (true) for storing the waiting threads. In theory, semaphores are often discussed, but in practice, semaphores aren't used so much. A semaphore only hold the state of one integer, so often it's rather inflexible and many are needed at once -- causing difficulty in understanding code. Also, the fact that any thread can release a semaphore is sometimes undesired. More object-oriented / higher-level synchronization primitives / abstractions such as "condition variables" and "monitors" are used instead.
In my case with Eclipse IDE, I had the same problem and the solution was:
1- Install the latest available API (SDK Platform & Google APIs)
2- Create the project with the following settings:
Pseudocode:
$base = log($size) / log(1024);
$suffix = array("", "k", "M", "G", "T")[floor($base)];
return pow(1024, $base - floor($base)) . $suffix;
let clickTimes = 0;
let timer = null;
roundBox.click = function (e) {
clearTimeout(timer);
timer = setTimeout(() => { // ????
console.log("single click");
}, 600);
clickTimes++;
if (clickTimes == 2) { // ??
clearTimeout(timer);
clickTimes = 0;
console.log("double click");
toggleExpanded(id);
}
}
I've implemented this in Kotlin like this:
fun Sheet.buildRow ( rowNum:Int ) : Row {
val templateRow = this.getRow( rowNum )
this.shiftRows( rowNum+1, sheet.lastRowNum, 1 )
val newRow = this.createRow( rowNum+1 )
templateRow.cellIterator().forEach {
newRow.createCell( it.columnIndex ).cellStyle = it.cellStyle
}
return templateRow
}
It doesn't copy the cell values, just the format. Should be applicable to Java as well.
improvement based on Jeetendra Chauhan's answer
$('ul.menu').each(function(){
$(this).children('li').sort((a,b)=>a.innerText.localeCompare(b.innerText)).appendTo(this);
});
why i consider it an improvement:
using each
to support running on more than one ul
using children('li')
instead of ('ul li')
is important because we only want to process direct children and not descendants
using the arrow function (a,b)=>
just looks better (IE not supported)
using vanilla innerText
instead of $(a).text()
for speed improvement
using vanilla localeCompare
improves speed in case of equal elements (rare in real life usage)
using appendTo(this)
instead of using another selector will make sure that even if the selector catches more than one ul still nothing breaks
In my case, it was Blend SDK missed out on TeamCity machine. This caused the error due incorrect way of assembly resolving then.
An output reg foo
is just shorthand for output foo_wire; reg foo; assign foo_wire = foo
. It's handy when you plan to register that output anyway. I don't think input reg
is meaningful for module
(perhaps task
). input wire
and output wire
are the same as input
and output
: it's just more explicit.
Yes, according to HTML5 drafts you can use the pattern
attribute to specify the allowed input using a regular expression. For some types of data, you can use special input fields like <input type=email>
. But these features still widely lack support or have qualitatively poor support.
Slice notation a[start_index:end_index:step]
return a[::2]
where start_index
defaults to 0
and end_index
defaults to the len(a)
.
Don't worry about any performance differences, they're going to be minimal in this case normally.
Method 2 is preferable because
it doesn't require mutating a collection that exists outside the lambda expression,
it's more readable because the different steps that are performed in the collection pipeline are written sequentially: first a filter operation, then a map operation, then collecting the result (for more info on the benefits of collection pipelines, see Martin Fowler's excellent article),
you can easily change the way values are collected by replacing the Collector
that is used. In some cases you may need to write your own Collector
, but then the benefit is that you can easily reuse that.
Use Process Explorer to find the process id. Then use Handle to find out what files are open.
Eg handle -p
I like this approach because you are using utilities from Microsoft itself.
Use pipe()
and write to the appropriate file descriptor.
https://docs.python.org/library/os.html#file-descriptor-operations
As others have said, it will only work when T is constrained to be a reference type. Without any constraints, you can compare with null, but only null - and that comparison will always be false for non-nullable value types.
Instead of calling Equals, it's better to use an IComparer<T>
- and if you have no more information, EqualityComparer<T>.Default
is a good choice:
public bool Compare<T>(T x, T y)
{
return EqualityComparer<T>.Default.Equals(x, y);
}
Aside from anything else, this avoids boxing/casting.
The Java Packager tool compiles, packages, and prepares Java and JavaFX applications for distribution. The javapackager command is the command-line version.
– Oracle's documentation
The javapackager
utility ships with the JDK. It can generate .exe files with the -native exe
flag, among many other things.
WinRun4j is a java launcher for windows. It is an alternative to javaw.exe and provides the following benefits:
- Uses an INI file for specifying classpath, main class, vm args, program args.
- Custom executable name that appears in task manager.
- Additional JVM args for more flexible memory use.
- Built-in icon replacer for custom icon.
- [more bullet points follow]
– WinRun4J's webpage
WinRun4J is an open source utility. It has many features.
Packages your JAR, assets and a JVM for distribution on Windows, Linux and Mac OS X, adding a native executable file to make it appear like a native app. Packr is most suitable for GUI applications.
– packr README
packr is another open source tool.
JSmooth is a Java Executable Wrapper. It creates native Windows launchers (standard .exe) for your java applications. It makes java deployment much smoother and user-friendly, as it is able to find any installed Java VM by itself.
– JSmooth's website
JSmooth is open source and has features, but it is very old. The last release was in 2007.
JexePack is a command line tool (great for automated scripting) that allows you to package your Java application (class files), optionally along with its resources (like GIF/JPG/TXT/etc), into a single compressed 32-bit Windows EXE, which runs using Sun's Java Runtime Environment. Both console and windowed applications are supported.
– JexePack's website
JexePack is trialware. Payment is required for production use, and exe files created with this tool will display "reminders" without payment. Also, the last release was in 2013.
InstallAnywhere makes it easy for developers to create professional installation software for any platform. With InstallAnywhere, you’ll adapt to industry changes quickly, get to market faster and deliver an engaging customer experience. And know the vulnerability of your project’s OSS components before you ship.
– InstallAnywhere's website
InstallAnywhere is a commercial/enterprise package that generates installers for Java-based programs. It's probably capable of creating .exe files.
As an alternative to .exe files, you can create a JAR file that automatically runs when double-clicked, by adding an entry point to the JAR manifest.
An excellent source of information on this topic is Excelsior's article "Convert Java to EXE – Why, When, When Not and How".
See also the companion article "Best JAR to EXE Conversion Tools, Free and Commercial".
Using Bryan McLemore answer, I extended it to support objects that throw in a safe manor with the Swift 2.0 defer ability.
func synchronized( lock:AnyObject, block:() throws -> Void ) rethrows

defer {
objc_sync_exit(lock)
}
try block()
}
[Your Drive]:\xampp\php\php.ini: In this file uncomment the following line:
extension=php_ldap.dll
Move the file: libsasl.dll, from [Your Drive]:\xampp\php to [Your Drive]:\xampp\apache\bin Restart Apache. You can now use functions of the LDAP Module!
You need to check out the attr
method in the jQuery docs. You are misusing it. What you are doing within the if statements simply replaces all image tags src
with the string specified in the 2nd parameter.
A better way to approach replacing a series of images source would be to loop through each and check it's source.
Example:
$('img').each(function () {
var curSrc = $(this).attr('src');
if ( curSrc === 'http://example.com/smith.gif' ) {
$(this).attr('src', 'http://example.com/johnson.gif');
}
if ( curSrc === 'http://example.com/williams.gif' ) {
$(this).attr('src', 'http://example.com/brown.gif');
}
});
Few answers appear to be using the newer ip
command (replacement for ifconfig
) so here is one that uses ip addr
, grep
, and awk
to simply print the IPv4 address associated with the wlan0
interface:
ip addr show wlan0|grep inet|grep -v inet6|awk '{print $2}'|awk '{split($0,a,"/"); print a[1]}'
While not the most compact or fancy solution, it is (arguably) easy to understand (see explanation below) and modify for other purposes, such as getting the last 3 octets of the MAC address like this:
ip addr show wlan0|grep link/ether|awk '{print $2}'|awk '{split($0,mac,":"); print mac[4] mac[5] mac[6]}'
Explanation: ip addr show wlan0
outputs information associated with the network interface named wlan0
, which should be similar to this:
4: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
link/ether dc:a6:32:04:06:ab brd ff:ff:ff:ff:ff:ff
inet 172.18.18.1/24 brd 172.18.18.255 scope global noprefixroute wlan0
valid_lft forever preferred_lft forever
inet6 fe80::d340:5e4b:78e0:90f/64 scope link
valid_lft forever preferred_lft forever
Next grep inet
filters out the lines that don't contain "inet" (IPv4 and IPv6 configuration) and grep -v inet6
filters out the remaining lines that do contain "inet6", which should result in a single line like this one:
inet 172.18.18.1/24 brd 172.18.18.255 scope global noprefixroute wlan0
Finally, the first awk
extract the "172.18.18.1/24" field and the second removes the network mask shorthand, leaving just the IPv4 address.
Also, I think it's worth mentioning that if you are scripting then there are often many richer and/or more robust tools for obtaining this information, which you might want to use instead. For example, if using Node.js there is ipaddr-linux
, if using Ruby there is linux-ip-parser
, etc.

I was having a similar or the same certification validation problem. I read that OpenSSL versions less than 1.0.2, which requests depends upon sometimes have trouble validating strong certificates (see here). CentOS 7 seems to use 1.0.1e which seems to have the problem.
I wasn't sure how to get around this problem on CentOS, so I decided to allow weaker 1024bit CA certificates.
import certifi # This should be already installed as a dependency of 'requests'
requests.get("https://example.com", verify=certifi.old_where())

this type of error usually occur when you try to access data through the index in which data data has not been assign. for example
//assign of data in to array
for(int i=0; i<10; i++){
arr[i]=i;
}
//accessing of data through array index
for(int i=10; i>=0; i--){
cout << arr[i];
}
the code will give error (vector subscript out of range) because you are accessing the arr[10] which has not been assign yet.

The error you mentioned happens when you have two versions of NumPy on your system. As you mentioned, the version of NumPy you imported is still not upgraded since you tried to upgrade it through pip (it will upgrade the version existing in '/Library/Python/2.7/site-packages'
).
However Python still loads the packages from '/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/numpy'
where the pre-installed packages live.
In order to upgrade that version you have to use easy_install
. The other way around this problem is using virtualenv
and setting up a new environment with all the requirements you need.
Knowing the error message would be rather valuable. It is meant to provide info, even though it doesn't make any sense to you it does to us. Being forced to guess, I'd say that the DLL is a 32-bit DirectX filter. In which case this should be the proper course of action:
cd c:\windows\syswow64
move ..\system32\dllname.ax .
regsvr32.exe dllname.ax
This must be run at an elevated command prompt so that UAC cannot stop the registry access that's required. Ask more questions about this at superuser.com
There is no guarantee that a GUID contains alpha characters. FFFFFFFF-FFFF-FFFF-FFFF-FFFFFFFFFFFF
is a valid GUID so is 00000000-0000-0000-0000-000000000000
and anything in between.
If you are using .NET 4.0, you can use the answer above for the Guid.Parse and Guid.TryParse. Otherwise, you can do something like this:
public static bool TryParseGuid(string guidString, out Guid guid)
{
if (guidString == null) throw new ArgumentNullException("guidString");
try
{
guid = new Guid(guidString);
return true;
}
catch (FormatException)

DateTime.UtcNow.ToString("s")

Depends upon the version. The If
operator in VB.NET 2008 is a ternary operator (as well as a null coalescence operator). This was just introduced, prior to 2008 this was not available. Here's some more info: Visual Basic If announcement

Dim foo as String = If(bar = buz, cat, dog)
[EDIT]
Prior to 2008 it was IIf
, which worked almost identically to the If
operator described Above.
Example:
Dim foo as String = IIf(bar = buz, cat, dog)
Since Python 3 timedelta
supports multiplication with floats, so now you can do:
import random
random_date = start + (end - start) * random.random()
given that start
and end
are of the type datetime.datetime
. For example, to generate a random datetime within the next day:
import random
from datetime import datetime, timedelta
start = datetime.now()
end = start + timedelta(days=1)
random_date = start + (end - start) * random.random()
function removeParam(parameter)
{
var url=document.location.href;
var urlparts= url.split('?');
if (urlparts.length>=2)
{
var urlBase=urlparts.shift();
var queryString=urlparts.join("?");
var prefix = encodeURIComponent(parameter)+'=';
var pars = queryString.split(/[&;]/g);
for (var i= pars.length; i-->0;)
if (pars[i].lastIndexOf(prefix, 0)!==-1)
pars.splice(i, 1);
url = urlBase+'?'+pars.join('&');
window.history.pushState('',document.title,url); // added this line to push the new url directly to url bar .
}
return url;
}
This will resolve your problem

Answers of getting all file names recursively with C++11 for Windows and Linux(with experimental/filesystem
):
For Windows:

#include <sys/stat.h>
#include <windows.h>
void getFiles_w(string path, vector<string>& files) {
intptr_t hFile = 0;
struct _finddata_t fileinfo;

if (strcmp(fileinfo.name, ".") != 0 && strcmp(fileinfo.name, "..") != 0)
getFiles(p.assign(path).append("/").append(fileinfo.name), files);
}
else {
files.push_back(p.assign(path).append("/").append(fileinfo.name));
}
} while (_findnext(hFile, &fileinfo) == 0);
}
}
For Linux:
#include <experimental/filesystem>
bool getFiles(std::experimental::filesystem::path path, vector<string>& filenames) {
namespace stdfs = std::experimental::filesystem;
// http://en.cppreference.com/w/cpp/experimental/fs/directory_iterator

return true;
}
else {
filenames.push_back(iter->path().string()) ;
cout << iter->path().string() << endl;
}
}
return false;

==
checks for reference equality, however when writing code like:
Integer a = 1;
Integer b = 1;
Java is smart enough to reuse the same immutable for a
and b
, so this is true: a == b
. Curious, I wrote a small example to show where java stops optimizing in this way:
public class BoxingLol {
public static void main(String[] args) {
for (int i = 0; i < Integer.MAX_VALUE; i++) {
Integer a = i;
Integer b = i;
if (a != b) {
System.out.println("Done: " + i);
System.exit(0);
}
}
System.out.println("Done, all values equal");
}
}
When I compile and run this (on my machine), I get:

Look at this page: http://www.webcodingtech.com/javascript/change-cursor.php. Looks like you can access cursor off of style. This page shows it being done with the entire page, but I'm sure a child element would work just as well.

Remove this from #info
:
margin-left:auto;
Add this for your header:

}
Do you need the fixed width etc.? I removed the in my opinion not necessary stuff and centered the header with text-align
.

A simpler, faster but slightly less random way is to use random.sample
instead of choosing each letter separately, If n-repetitions are allowed, enlarge your random basis by n times e.g.
import random
import string
char_set = string.ascii_uppercase + string.digits
print ''.join(random.sample(char_set*6, 6))
Note: random.sample prevents character reuse, multiplying the size of the character set makes multiple repetitions possible, but they are still less likely then they are in a pure random choice. If we go for a string of length 6, and we pick 'X' as the first character, in the choice example, the odds of getting 'X' for the second character are the same as the odds of getting 'X' as the first character. In the random.sample implementation, the odds of getting 'X' as any subsequent character are only 6/7 the chance of getting it as the first character
This works with font awesome:
<button class="btn btn-outline-success">
<i class="fa fa-print" aria-hidden="true"></i>
Print
</button>
Floats are used to store a wider range of number than can be fit in an integer. These include decimal numbers and scientific notation style numbers that can be bigger values than can fit in 32 bits. Here's the deep dive into them: http://en.wikipedia.org/wiki/Floating_point
HashMap
basically contains Entry
which subsequently contains Key(Object)
and Value(Object)
.Internally HashSet
are HashMap
and HashMap
do replace values as some of you already pointed..but does it really replaces the keys???No ..and that is the trick here. HashMap
keeps its value as key in the underlying HashMap
and value is just a dummy object.So if u try to reinsert same Value in HashMap(Key in underlying Map).It just replaces the dummy value and not the Key(Value for HashSet).
Look at the below code for HashSet Class:
public boolean [More ...] add(E e) {
return map.put(e, PRESENT)==null;
}
Here e is the value for HashSet but key for underlying map.and key is never replaced. Hope i am able to clear the confusion.
I think you don't have to use sub query in this scenario.You can directly left outer join the DEPRMNT table .
While using Left Outer Join ,don't use columns in the RHS table of the join in the where condition, you ll get wrong output
You have your storyboard set up to expect an outlet called tableView
but the actual outlet name is myTableView
.
If you delete the connection in the storyboard and reconnect to the right variable name, it should fix the problem.
So you know the key, value pair that you want to delete in advance? It's just much clearer to do this, then:
table.delete(key);
for (K key: table.keySet()) {
// do whatever you need to do with the rest of the keys
}
I finally found a solution. I wasted hours just trying to figure what this issue was. I tried deleting all those files suggested above and it didn't work for me, I tried adding new inbound rules to firewall for myslqd.exe and it didn't work. The thing that is causing this error is MySQL port is misconfigured and the fix was really simple. if you are using Wamp or Xampp go to Main Folder/Bin/mysql/mysql/ and find a file named my.ini
Open my.ini file press CTRL + F and inside it search for PORT and change whatever value of port to - 3306 and save file;
After that go to Wamp icon at the bottom of the taskbar (system tray) and left click choose mysql option and click "test port 3306 used" and see if it gives you any error. you can also click use other port other than whatever is shown there and port 3306.
Goodluck. if it works comment.
To get dynamic tagging to work with ajax, here's what I did.
Select2 version 3.5
This is easy in version 3.5 because it offers the createSearchChoice
hook. It even works for multiple select, as long as multiple: true
and tags: true
are set.
HTML
<input type="hidden" name="locations" value="Whistler, BC" />
JS
$('input[name="locations"]').select2({
tags: true,
multiple: true,
createSearchChoice: function(term, data) {
if (!data.length)
return { id: term, text: term };
},
ajax: {
url: '/api/v1.1/locations',
dataType: 'json'
}
});
The idea here is to use select2's createSearchChoice
hook which passes you both the term
that the user entered and the ajax response (as data
). If ajax returns an empty list, then tell select2 to offer the user-entered term
as an option.
Demo: https://johnny.netlify.com/select2-examples/version3
Select2 version 4.X
Version 4.X doesn't have a createSearchChoice
hook anymore, but here's how I did the same thing.
HTML
<select name="locations" multiple>
<option value="Whistler, BC" selected>Whistler, BC</option>
</select>
JS
$('select[name="locations"]').select2({
ajax: {
url: '/api/v1.1/locations',
dataType: 'json',
data: function(params) {
this.data('term', params.term);
return params;
},
processResults: function(data) {
if (data.length)
return {
results: data
};
else
return {
results: [{ id: this.$element.data('term'), text: this.$element.data('term') }]
};
}
}
});
The ideas is to stash the term that the user typed into jQuery's data store inside select2's data
hook. Then in select2's processResults
hook, I check if the ajax response is empty. If it is, I grab the stashed term that the user typed and return it as an option to select2.
Mature, simple to use and has lots of features if simple isn't enought: Nodemailer: https://github.com/andris9/nodemailer (note correct url!)
I guess you should install CA certificate form one if authority canter:
ssl_trusted_certificate ssl/SSL_CA_Bundle.pem;
No need to create a GD resource, as someone else suggested.
$input = 'http://images.websnapr.com/?size=size&key=Y64Q44QLt12u&url=http://google.com';
$output = 'google.com.jpg';
file_put_contents($output, file_get_contents($input));
Note: this solution only works if you're setup to allow fopen access to URLs. If the solution above doesn't work, you'll have to use cURL.
Use REN
Command
Ren
is for rename
ren ( where the file is located ) ( the new name )
example
ren C:\Users\&username%\Desktop\aaa.txt bbb.txt
it will change aaa.txt to bbb.txt
Your code will be :
ren (file located)AAA_a001.jpg a001.AAA.jpg
ren (file located)BBB_a002.jpg a002.BBB.jpg
ren (file located)CCC_a003.jpg a003.CCC.jpg
and so on
IT WILL NOT WORK IF THERE IS SPACES!
Hope it helps :D
For the record:
"Data at the root level is invalid" means that you have attempted to parse something that is not an XML document. It doesn't even start to look like an XML document. It usually means just what you found: you're parsing something like the string "C:\inetpub\wwwroot\mysite\officelist.xml".
Note that -p
is an argument to the mkdir
command specifically, not the whole of Unix. Every command can have whatever arguments it needs.
In this case it means "parents", meaning mkdir
will create a directory and any parents that don't already exist.
Try this:
dataTable.Columns["Marks"].ColumnName = "SubjectMarks";
I have never been a fan of closing blocks of PHP to output content to the browser, I prefer to have my output captured so if at some point within my logic I decide I want to change my output (after output has already been sent) I can just delete the current buffer.
But as Pekka said, the main reason you are having issues with your javascript inclusion is because your using href
to specify the location of the js file where as you should be using src
.
If you have a functions file with your functions inside then add something like:
function js_link($src)
{
if(file_exists("my/html/root/" . $src))
{
//we know it will exists within the HTTP Context
return sprintf("<script type=\"text/javascript\" src=\"%s\"></script>",$src);
}
return "<!-- Unable to load " . $src . "-->";
}
The n in your code without the need for closing your blocks with ?>
you can just use:
echo js_link("jquery/1.6/main.js");
@Egidius, when creating an XMLHttpRequest, you should use
var xhr = new XMLHttpRequest({mozSystem: true});
What is mozSystem?
mozSystem Boolean: Setting this flag to true allows making cross-site connections without requiring the server to opt-in using CORS. Requires setting mozAnon: true, i.e. this can't be combined with sending cookies or other user credentials. This only works in privileged (reviewed) apps; it does not work on arbitrary webpages loaded in Firefox.
Changes to your Manifest
On your manifest, do not forget to include this line on your permissions:
"permissions": {
"systemXHR" : {},
}
This is a known issue in Chrome and resolved in latest versions. Please refer https://bugs.chromium.org/p/chromium/issues/detail?id=942440 for more details.
If you want to use hex codes, you should add -e
option to enable interpretation of backslash escapes by echo (but the result is the same as with echo
CtrlRCtrlB). And as wallyk said, you probably want to add -n
to prevent the output of a newline:
echo -en '\x12\x02' > /dev/ttyS0
Also make sure that /dev/ttyS0
is the port you want.
use
header("Location: index.php"); //this work in my site
read more on header() at php documentation.
I use this helper method to render components and return an component instance. Methods can be called on that instance.
static async renderComponentAt(componentClass, props, parentElementId){
let componentId = props.id;
if(!componentId){
throw Error('Component has no id property. Please include id:"...xyz..." to component properties.');
}
let parentElement = document.getElementById(parentElementId);
return await new Promise((resolve, reject) => {
props.ref = (component)=>{
resolve(component);
};
let element = React.createElement(componentClass, props, null);
ReactDOM.render(element, parentElement);
});
}
I'm not exactly sure what the problem is, as your example code has several errors and doesn't really make it clear what you're trying to do. But here's how you add to a specific row of a 2D vector:
// declare 2D vector
vector< vector<int> > myVector;
// make new row (arbitrary example)
vector<int> myRow(1,5);
myVector.push_back(myRow);
// add element to row
myVector[0].push_back(1);
Does this answer your question? If not, could you try to be more specific as to what you are having trouble with?
You don't need the separate fill item. In fact, it's invalid. You just have to add a solid
block to the shape
. The subsequent stroke
draws on top of the solid
:
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners android:radius="5dp" />
<solid android:color="@android:color/white" />
<stroke
android:width="1dip"
android:color="@color/bggrey" />
</shape>
You also don't need the layer-list
if you only have one shape
.
Using docker-compose
, services are exposed to each other by name by default. Docs.
You could also specify an alias like;
version: '2.1'
services:
mongo:
image: mongo:3.2.11
redis:
image: redis:3.2.10
api:
image: some-image
depends_on:
- mongo
- solr
links:
- "mongo:mongo.openconceptlab.org"
- "solr:solr.openconceptlab.org"
- "some-service:some-alias"
And then access the service using the specified alias as a host name, e.g mongo.openconceptlab.org
for mongo
in this case.
And for those of you using an anonymous expression:
await Task.Run(async () =>
{
SQLLiteUtils slu = new SQLiteUtils();
await slu.DeleteGroupAsync(groupname);
});
Use the Distinct operator:
var idList = yourList.Select(x=> x.ID).Distinct();
The compiler is using the UTF-8 character encoding to read your source file. But the file must have been written by an editor using a different encoding. Open your file in an editor set to the UTF-8 encoding, fix the quote mark, and save it again.
Alternatively, you can find the Unicode point for the character and use a Unicode escape in the source code. For example, the character A
can be replaced with the Unicode escape \u0041
.
By the way, you don't need to use the begin- and end-line anchors ^
and $
when using the matches()
method. The entire sequence must be matched by the regular expression when using the matches()
method. The anchors are only useful with the find()
method.
a_list = [
[1,2],
[1,2],
[2,3],
[3,4]
]
print (list(map(list,set(map(tuple,a_list)))))
outputs: [[1, 2], [3, 4], [2, 3]]
if condition is null then it is number
IF(rtrim(P_COD_LEGACY, '0123456789') IS NULL) THEN
return 1;
ELSE
return 0;
END IF;
This is how you create a zip file from a source file:
String srcFilename = "C:/myfile.txt";
String zipFile = "C:/myfile.zip";
try {
byte[] buffer = new byte[1024];
FileOutputStream fos = new FileOutputStream(zipFile);
ZipOutputStream zos = new ZipOutputStream(fos);
File srcFile = new File(srcFilename);
FileInputStream fis = new FileInputStream(srcFile);
zos.putNextEntry(new ZipEntry(srcFile.getName()));
int length;
while ((length = fis.read(buffer)) > 0) {
zos.write(buffer, 0, length);
}
zos.closeEntry();
fis.close();
zos.close();
}
catch (IOException ioe) {
System.out.println("Error creating zip file" + ioe);
}
On windows use the name of the table in quotes:
TABLE "user";
or SELECT * FROM "user";
You have compiled your code with references to the correct math.h header file, but when you attempted to link it, you forgot the option to include the math library. As a result, you can compile your .o object files, but not build your executable.
As Paul has already mentioned add "-lm
" to link with the math library in the step where you are attempting to generate your executable.
Why for
sin()
in<math.h>
, do we need-lm
option explicitly; but, not forprintf()
in<stdio.h>
?
Because both these functions are implemented as part of the "Single UNIX Specification". This history of this standard is interesting, and is known by many names (IEEE Std 1003.1, X/Open Portability Guide, POSIX, Spec 1170).
This standard, specifically separates out the "Standard C library" routines from the "Standard C Mathematical Library" routines (page 277). The pertinent passage is copied below:
Standard C Library
The Standard C library is automatically searched by
cc
to resolve external references. This library supports all of the interfaces of the Base System, as defined in Volume 1, except for the Math Routines.Standard C Mathematical Library
This library supports the Base System math routines, as defined in Volume 1. The
cc
option-lm
is used to search this library.
The reasoning behind this separation was influenced by a number of factors:
The pressures that fed into the decision to put -lm
in a different library probably included, but are not limited to:
sin()
and putting it in a custom built library.In any case, it is now part of the standard to not be automatically included as part of the C language, and that's why you must add -lm
.
One more :
var a = document.createElement('a');
a.setAttribute('href', dataUri);
a.setAttribute('download', filename);
var aj = $(a);
aj.appendTo('body');
aj[0].click();
aj.remove();
Values like M_PI, M_PI_2, M_PI_4, etc are not standard C++ so a constexpr seems a better solution. Different const expressions can be formulated that calculate the same pi and it concerns me whether they (all) provide me the full accuracy. The C++ standard does not explicitly mention how to calculate pi. Therefore, I tend to fall back to defining pi manually. I would like to share the solution below which supports all kind of fractions of pi in full accuracy.
#include <ratio>
#include <iostream>
template<typename RATIO>
constexpr double dpipart()
{
long double const pi = 3.14159265358979323846264338327950288419716939937510582097494459230781640628620899863;
return static_cast<double>(pi * RATIO::num / RATIO::den);
}
int main()
{
std::cout << dpipart<std::ratio<-1, 6>>() << std::endl;
}
