Change localhost:8080 to localhost:3306.

Add path of your PHP to Windows System Path. The path should contain php.exe.

After adding the path open a new command prompt and make sure php.exe is in path by typing

C:\>php --help

Once you see proper help message from above, enable the php_ldap.dll extension in php.ini

Also copy php_ldap.dll from php/ext directory to apache/bin folder

Restart wamp and phpinfo() will now show ldap enabled.

This is how I've managed to load CURL correctly. In my case php was installed from zip package, so I had to add php directory to PATH environment variable.

I assume you are using windows. Open the command prompt and type ipconfig and find out your local address (on your pc) it should look something like 192.168.1.13 or 192.168.0.5 where the end digit is the one that changes. It should be next to IPv4 Address.

If your WAMP does not use virtual hosts the next step is to enter that IP address on your phones browser ie http://192.168.1.13 If you have a virtual host then you will need root to edit the hosts file.

If you want to test the responsiveness / mobile design of your website you can change your user agent in chrome or other browsers to mimic a mobile.

See http://googlesystem.blogspot.co.uk/2011/12/changing-user-agent-new-google-chrome.html.

Edit: Chrome dev tools now has a mobile debug tool where you can change the size of the viewport, spoof user agents, connections (4G, 3G etc).

If you get forbidden access then see this question WAMP error: Forbidden You don't have permission to access /phpmyadmin/ on this server. Basically, change the occurrances of deny,allow to allow,deny in the httpd.conf file. You can access this by the WAMP menu.

To eliminate possible causes of the issue for now set your config file to

<Directory />
    Options FollowSymLinks
    AllowOverride All
    Order allow,deny
    Allow from all
    <RequireAll>
        Require all granted
    </RequireAll>
</Directory>

As thatis working for my windows PC, if you have the directory config block as well change that also to allow all.

Config file that fixed the problem:

https://gist.github.com/samvaughton/6790739

Problem was that the /www apache directory config block still had deny set as default and only allowed from localhost.

Try using fake sendmail to send emails in a WAMP enviroment.

http://jesin.tk/using-sendmail-on-windows/

Check your apache error log. I had this error "[error] (OS 5)Access is denied. : could not open transfer log file C:/wamp/logs/access.log. Unable to open logs" Then I rename my "access.log" to other name, you can delete if you don't need/never see your access log. Then restart your apache service. This happen because the file size too big. I think if you trying to open this file using notepad, it will not open, I tried to open that before. Hope it help.

Click wamp icon :

1- apache -> httpd.conf (A notepad file will be opened)

2- Find 80

3 -Replace with 81

Listen 12.34.56.78:81 Listen 0.0.0.0:81 Listen [::0]:81

4- Restart wamp services

!!Done

The simplest solution is to disable the IIS service from the services snapin

(use the start menu -> search programs and files -> services.msc to launch the snapin )

This will stop IIS using port 80. Then change Apache back to using port 80.

I had the same problem, and I solved it by installing :

• Redistribuable Visual C++ pour Visual Studio 2012 Update 4 (6.9 MB)
• Redistributable Visual C++ pour Visual Studio 2015 Update 1 (14.1 MB)

NB : 64 bit installation was enough, I had to uninstall / reinstall Wamp after that

When installing Wamperserver 3 on windows 10, it now gives a nice big warning during the install telling you it won't work unless you install many of these packages.

It worked for me after I followed the instructions and then restart the computer and reinstalled.

--- Installation of Wampserver --- BEFORE proceeding with the installation of Wampserver, you must ensure that certain elements are installed on your system, otherwise Wampserver will absolutely not run, and in addition, the installation will be faulty and you need to remove Wampserver BEFORE installing the elements that were missing. Make sure you are "up to date" in the redistributable packages VC9, VC10, VC11, VC13 , VC14 and VC15 See --- Visual C++ Packages below.

--- Do not install Wampserver OVER an existing version, follow the advice: - Install a new version of Wampserver: http://forum.wampserver.com/read.php?2,123606 If you install Wampserver over an existing version, not only it will not work, but you risk losing your existing databases.

--- Install Wampserver in a folder at the root of a disk, for example C:\wamp or D:\wamp. Take an installation path that does not include spaces or diacritics; Therefore, no installation in c: \ Program Files\ or C: \ Program Files (x86\ We must BEFORE installing, disable or close some applications: - Close Skype or force not to use port 80 Item No. 04 of the Wampserver TROUBLESHOOTING TIPS:http://forum.wampserver.com/read.php?2,134915 - Disable IIS Item No. 08 of the Wampserver TROUBLESHOOTING TIPS:http://forum.wampserver.com/read.php?2,134915 If these prerequisites are not in place, Press the Cancel button to cancel the installation, then apply the prerequisites and restart the installation.

This works on Wamp 3+.

• Go to wamp folder (wamp/ or wamp64/)
• Open wampmanager.conf
• Find urlAddLocalhost param and set it on: urlAddLocalhost = "on"

There should not be the need to tweak the index.php in www folder.

Check whether MySQL server is running at all. If you not run apache server(or any server you use) this could happen. After run your local server and refresh the page.

Use this :

php -r "readfile('https://getcomposer.org/installer');" | php

The values indicated by Ram Sharma might need to be changed in Wamp alias configuration files instead.

In <wamp_dir>/alias/phpmyadmin.conf, in the <Directory> section:

  php_admin_value upload_max_filesize 1280M
  php_admin_value post_max_size 1280M
  php_admin_value max_execution_time 1800

WAMP stands for Windows,Apache,Mysql,Php

XAMPP stands for X-os,Apache,Mysql,Php,Perl. (x-os means it can use for any operating system)

Advantages of XAMPP:

• It is cross-platform software

• It possesses many other essential modules such as phpMyAdmin, OpenSSL, MediaWiki, WordPress, Joomla and more.

• it is easy to configure and use.

Advantages of WAMP:

• It is easy to Use. (Changing Configuration)

• WAMP is Available for both 64 bit and 32-bit system.

if you are running projects which have specific version requirements WAMP is better choice because you can switch between multiple versions. for example 7x and PHP 5x or Magento2.2.4 won't work on php7.2 but Magento2.3.needs php7.2 or up to work.

Before you can fix anything you need to know which service has not started, Apache or MySQL.

As the TEST PORT 80 utility is saying Apache is running its probably the MySQL service that has not started. Unless you have another Apache running!

So which service has not started???

If the wampmanager icon is not GREEN then one of the services ( Apache/MySQL ) has not started properly.

How to tell which service is not running if the wampmanager icon is orange.

Left click the wampmanager icon to reveal the menu-> Apache -> Service If the Start/Resume service menu is Green then Apache IS NOT running.

Left click the wampmanager icon to reveal the menu-> MySQL -> Service If the Start/Resume service menu is Green then MySQL IS NOT running.

If Apache is the service that is not running it is normally, but not always, because something else has captured port 80.

Now do, Left click the wampmanager icon to reveal the menu-> Apache -> Service -> Test port 80 This will launch a command window and display some information about what, if anything is using port 80.

Whatever it is should be re-configured to not use port 80 or uninstalled if you are not using it.

If port 80 is not the problem look for errors in the appropriate error log ( use the wamp manager menus to view the error logs )

If these do not exists or show no errors then also check the Windows Event Viewer Start -> Administrative Tools -> Event Viewer And look in the 'Windows Logs' -> Application' section accessed from the menu on the left of the dialog for error messages from Apache and or MySQL.

If its MYSQL that has not started.

Check the mysql error log by using the menus

wampmanager->MySQL->error log

Check the Windows Event log for messages from MYSQL

Check you dont have another MYSQL Server instance running.

How to Configure SKYPE so it does not require port 80 or 443

Run SKYPE then using the menus do this: Tools -> Options -> Advanced -> Connection Un-Check the checkbox next to 'Use port 80 and 443 as alternatives for incomming connections' Now restart SKYPE for these changes to take effect.

If you are running Windows 8 SKYPE comes as an app and this cannot ( as yet ) be configured in this way. However if you uninstall the SKYPE app and install SKYPE in the old way, you can reconfigure it, and it works just as well.

The steps are as follows :

1. Close WAMP (if running)
2. Navigate to WAMP\bin\php\(your version of php)\
3. Edit php.ini
4. Search for curl, uncomment extension=php_curl.dll
5. Navigate to WAMP\bin\Apache\(your version of apache)\bin\
6. Edit php.ini
7. Search for curl, uncomment extension=php_curl.dll
8. Save both
9. Restart WAMP

Yea, this was a pain for me as well.

So what i did was find the "Start Wampserver", just hit the start button and type it in.

Then right click on it , select properties. I set it to run in XP servive pack 3 on the capatability tab. I also checked the box "Run this program as an administrator".

Then I right clicked the WAMPSERVER on the System Tray, and re-started all services. This worked perfect for me, hope this will help you as well.

Rob

Guzzle, which is used by cartalyst/stripe, will do the following to find a proper certificate archive to check a server certificate against:

1. Check if openssl.cafile is set in your php.ini file.
2. Check if curl.cainfo is set in your php.ini file.
3. Check if /etc/pki/tls/certs/ca-bundle.crt exists (Red Hat, CentOS, Fedora; provided by the ca-certificates package)
4. Check if /etc/ssl/certs/ca-certificates.crt exists (Ubuntu, Debian; provided by the ca-certificates package)
5. Check if /usr/local/share/certs/ca-root-nss.crt exists (FreeBSD; provided by the ca_root_nss package)
6. Check if /usr/local/etc/openssl/cert.pem (OS X; provided by homebrew)
7. Check if C:\windows\system32\curl-ca-bundle.crt exists (Windows)
8. Check if C:\windows\curl-ca-bundle.crt exists (Windows)

You will want to make sure that the values for the first two settings are properly defined by doing a simple test:

echo "openssl.cafile: ", ini_get('openssl.cafile'), "\n";
echo "curl.cainfo: ", ini_get('curl.cainfo'), "\n";

Alternatively, try to write the file into the locations indicated by #7 or #8.

The problem may lie in you don't have enabled openssl extention in your php.ini file

go to your php.ini file end remove ; in line where extension=openssl is

Of course in question code there is a part of code responsible for checking whether extension is loaded or not but maybe some uncautious forget about it

Check your my.cnf file in your MySQL program directory, look for

[mysqld]
datadir=

The datadir is the location where your MySQL database is stored.

For me, using OS X Catalina: Changing from AllowOverride None to AllowOverride All is the one that works.

httpd.conf is located on /etc/apache2/httpd.conf.

Env: PHP7. MySQL8.

I wanted to run my server online and not under localhost / 127.0.0.1 and had the forbidden message. I am running the WAMP 2.2 server (Apache 2.4.2 / PHP 5.4.3 / MySQL 5.5.24) on Windows 7 64 bit. What worked for me is the following:

1. Press the startup WAMP icon in the menu
2. Choose Apache folder
3. Choose the file httpd.conf
4. Under the Directory tab section (section with "# Online --> Require all granted" text), I had the "Require local" option which I changed to "Require all granted"
5. Restart all services of the WAMP

Again, it worked for me and from this thread I understand that there are many cases in which you may get the above error message so if mine does not work, try other solutions.

Good luck.

(I hope it helps someone like it helped me. I did not find any one of the solutions above working for me.)

It depends on your OS, but if you are on Windows XP, you need to go to Systems Properties, then Advanced, then Environment Variables, and include the php binary path to the %PATH% variable.

Locate it by browsing your WAMP directory. It's called php.exe

localhost is a special hostname that almost always resolves to 127.0.0.1. If you ask someone else to connect to http://localhost they'll be connecting to their computer instead or yours.

To share your web server with someone else you'll need to find your IP address or your hostname and provide that to them instead. On windows you can find this with ipconfig /all on a command line.

You'll also need to make sure any firewalls you may have configured allow traffic on port 80 to connect to the WAMP server.

Options>Advanced>connections

Uncheck the option :

Use port 80 and 443 as alternative....

I run on wamp and I had this problem once. There can be many factors to this though there is 5 main ones that come to my mind.

1st. A program can cause this(Even antivirus software just depends what you have.)

2nd. Is your computer full or using alot of space this happen to a partner site of mine.

3rd. Check your regerstry files there could be errors or other things. (This end up being my problem.)

4th. After you uninstalled it did you manually delete the files that were left on your computer.(Yes even after you uninstall with wamp it has a tendency to leave a folder or 2 with some important data on it. When you install this will not be remodified and will stay the same.)

5th. Download the latest wamp or the lastest stable version of it.

Hope one of these things help.

WAMP Server may turn orange for various reason as it is not working. This is also a another type of issue. that can be due to webservices is running in services.msc This is explained in the below blog. Please try it. How to resolve HTTP Error 404 and launch localhost with WAMP Server for PHP & MySql?

Here's how I get there using Version 3.0.6 on Windows

just do these steps if you don't need your old php version:

• open wamp and right click on wamp manager than go : tools/Change PHP CLI Version than change php version to latest
• another time right click on wamp manager than go : tools/Delete unuserd versions and delete the oldest version which your system insist on it to be your pc php version :D
• go to control panel/user account/change my environment variables and in PATH variable click edit and add your latest php version path which is in your wamp server bin folder
• close all command lines or IDEs and restart them and check for php -v

this works well

I have found that if you are using ammps that for some reason its always forbidden when its in your root folder so i put it in the directory above my root folder and made a alias in the httpd.conf using this

Alias /phpmyadmin "C:/Program Files (x86)/Ampps/phpMyAdmin"

please note i am using ammps and i dont know for sure if it will work for others but its worth a try ;)

after your pc connects to other pc use these 4 step:
4 steps:
1- Edit this file: httpd.conf
for that click on wamp server and select Apache and select httpd.conf
2- Find this text: Deny from all
in the below tag:

  <Directory "c:/wamp/www"><!-- maybe other url-->

    #
    # Possible values for the Options directive are "None", "All",
    # or any combination of:
    #   Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews
    #
    # Note that "MultiViews" must be named *explicitly* --- "Options All"
    # doesn't give it to you.
    #
    # The Options directive is both complicated and important.  Please see
    # http://httpd.apache.org/docs/2.4/mod/core.html#options
    # for more information.
    #
    Options Indexes FollowSymLinks

    #
    # AllowOverride controls what directives may be placed in .htaccess files.
    # It can be "All", "None", or any combination of the keywords:
    #   AllowOverride FileInfo AuthConfig Limit
    #
    AllowOverride All

    #
    # Controls who can get stuff from this server.
    #
#    Require all granted
#   onlineoffline tag - don't remove
     Order Deny,Allow
    Deny from all
     Allow from 127.0.0.1
     Allow from ::1
     Allow from localhost
</Directory>

3- Change to: Deny from none
like this:

<Directory "c:/wamp/www">

    #
    # Possible values for the Options directive are "None", "All",
    # or any combination of:
    #   Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews
    #
    # Note that "MultiViews" must be named *explicitly* --- "Options All"
    # doesn't give it to you.
    #
    # The Options directive is both complicated and important.  Please see
    # http://httpd.apache.org/docs/2.4/mod/core.html#options
    # for more information.
    #
    Options Indexes FollowSymLinks

    #
    # AllowOverride controls what directives may be placed in .htaccess files.
    # It can be "All", "None", or any combination of the keywords:
    #   AllowOverride FileInfo AuthConfig Limit
    #
    AllowOverride All

    #
    # Controls who can get stuff from this server.
    #
#    Require all granted
#   onlineoffline tag - don't remove
     Order Deny,Allow
    Deny from none
     Allow from 127.0.0.1
     Allow from ::1
     Allow from localhost

4- Restart Apache
Don't forget restart Apache or all servises!!!

Change the port 80 to port 8080 and restart all services and access like localhost:8080/

It will work fine.

Open the port where your system is running (sample 8080). Open the port everywhere... Modem, firewalls, etc etc etc.

THen, send your ip + port to the person who will use it.

sample: http://200.200.200.200:8080/mySite/

I find the best (and least frustrating) path is to start with Allow from All, then, when you know it will work that way, scale it back to the more secure Allow from 127.0.0.1 or Allow from ::1 (localhost).

As long as your firewall is configured properly, Allow from all shouldn't cause any problems, but it is better to only allow from localhost if you don't need other computers to be able to access your site.

Don't forget to restart Apache whenever you make changes to httpd.conf. They will not take effect until the next start.

Hopefully this is enough to get you started, there is lots of documentation available online.

Showing image in title bar is easy. please follow the steps :

a) first save you image some where in the folder and name like favicon. b) then use below line inside head tag of the html view

<link rel="icon" type="image/png" href="image_url" />

c) Here you must know the path of your file, where you have saved the image d) save your image url in place of image_url e) save your working.

Windows 10 x64 released August 2015 - same issue arising. MSVCR110.dll is also found in the sysWOW64 folder (which is where I found it, copying to system32 does not help). To resolve:

1. uninstall the x86 versions of VC 11 vcredist_x64/86.exe for 2012 and 2013
2. uninstall WAMP Server 2.5
3. delete (maybe back up first) the WAMP folder
4. restart windows
5. reinstall WAMP 2.5

Hopefully like me you have a MySQL database backup handy!

If you're using Windows 10, as I am, and the port is occupied by Microsoft-IIS/10.0, change the lines 62 and 63, of the httpd.conf, from:

Listen 0.0.0.0:80
Listen [::0]:80

To:

Listen 0.0.0.0:8080
Listen [::0]:8080

As the people here suggested.

And also, change the line 221, from:

ServerName localhost:80

To:

ServerName localhost:8080

Now, your host will be available at http://localhost:8080/.

In lieu of changing the port, I reclaimed port 80 as being used by IIS.

So I went to services, and stopped the following:

1. World Wide Web Publishing Services.
2. Web Management Service
3. Web Deployment Agent Service.

set them to manual so that it will not start on dev environment restart.

I had the same issue, tried all nothing works, following works for me

Following is what i had

#onlineoffline tag - don't remove

Require local

Change to

Require all granted
Order Deny,Allow
Allow from all

My solution on Windows 10 was just to stop IIS (Internet Information Services).

I have some experiences in Wamp 3.0 and Apache 2.4 .

After all works do this steps:

1- Disable nod32.

2- Add this line to <VirtualHost *:80> block in httpd-vhosts.conf file:

Require ip 192.168.100 #client ip, allow 192.168.100.### ip's access

As an alternative to PHPMailer, Pear's Mail and others you could use the Zend's library

  $config = array('auth' => 'login',
                   'ssl' => 'ssl',
                   'port'=> 465,
                   'username' => '[email protected]',
                   'password' => 'XXXXXXX');

 $transport = new Zend_Mail_Transport_Smtp('smtp.gmail.com', $config);
 $mail = new Zend_Mail();
 $mail->setBodyText('This is the text of the mail.');
 $mail->setFrom('[email protected]', 'Some Sender');
 $mail->addTo('[email protected]', 'Some Recipient');
 $mail->setSubject('TestSubj');
 $mail->send($transport); 

That is my set up in localhost server and I can able to see incoming mail to my mail box.

EasyPHP is very good :

• lightweight & portable : no windows service (like wamp)
• easy to configure (all configuration files in the same folder : httpd.conf, php.ini & my.ini)
• auto restarts apache when you edit httpd.conf

WAMP or UWAMP are good choices if you need to test with multiples versions of PHP and Apache.

But you can also use multiple versions of PHP with EasyPHP (by downloading the PHP version you need on php.net, and loading this version by editing httpd.conf) :

LoadModule php4_module "${path}/php4/php4apache2_2.dll"

If you are using Microsoft Drivers 3.1, 3.0, and 2.0. Please check your PHP version already install with IIS.

Use this script to check the php version:

<?php echo phpinfo(); ?>

OR

If you have installed PHP Manager in IIS using web platform Installer you can check the version from it.

Then:
If you are using new PHP version (5.6) please download Drivers from here

For PHP version Lower than 5.6 - please download Drivers from here

• PHP Driver version 3.1 requires PHP 5.4.32, or PHP 5.5.16, or later.
• PHP Driver version 3.0 requires PHP 5.3.0 or later. If possible, use PHP 5.3.6, or later.
• PHP Driver version 2.0 driver works with PHP 5.2.4 or later, but not with PHP 5.4. If possible, use PHP 5.2.13, or later.

Then use the PHP Manager to add that downloaded drivers into php config file.You can do it as shown below (browse the files and press OK). Then Restart the IIS Server

If this method not work please change the php version and try to run your php script.

Tip:Change the php version to lower and try to understand what happened.then you can download relevant drivers.

I used Mercury/32 and Pegasus Mail to get the mail() functional. It works great too as a mail server if you want an email address ending with your domain name.

1. Go to C:\xampp\phpMyAdmin

2. Edit the config.inc.php file

3. Replace $cfg['Servers'][$i]['auth_type'] = 'config'; by $cfg['Servers'][$i]['auth_type'] = 'cookie';

For now on the PHPMyAdmin will ask you for your password, no more error.

Also beware that "setup" (i.e. localhost/phpmyadmin/setup) has an error in the way it handles the "no password" option. While it creates a line that says:

$cfg['Servers'][$i]['nopassword'] = true;

the actual name of the parameter should be as shown here:

$cfg['Servers'][$i]['AllowNoPassword'] = true;

This "setup" error exists as of today, Oct 20, 2015.

just add following line in wamp/alias/phpmyadmin.conf
Allow from ::1

so it will look something like this depending your phpmyadmin version.

<Directory "c:/wamp/apps/phpmyadmin3.5.1/">
Options Indexes FollowSymLinks MultiViews
AllowOverride all
    Order Deny,Allow
Deny from all
Allow from 127.0.0.1
Allow from ::1
</Directory> 

It gets revealed when you debug using the debug() function. Suppose you want to see the underlying code in t() transpose function. Just typing 't', doesn't reveal much.

>t 
function (x) 
UseMethod("t")
<bytecode: 0x000000003085c010>
<environment: namespace:base>

But, Using the 'debug(functionName)', it reveals the underlying code, sans the internals.

> debug(t)
> t(co2)
debugging in: t(co2)
debug: UseMethod("t")
Browse[2]> 
debugging in: t.ts(co2)
debug: {
    cl <- oldClass(x)
    other <- !(cl %in% c("ts", "mts"))
    class(x) <- if (any(other)) 
        cl[other]
    attr(x, "tsp") <- NULL
    t(x)
}
Browse[3]> 
debug: cl <- oldClass(x)
Browse[3]> 
debug: other <- !(cl %in% c("ts", "mts"))
Browse[3]> 
debug: class(x) <- if (any(other)) cl[other]
Browse[3]>  
debug: attr(x, "tsp") <- NULL
Browse[3]> 
debug: t(x)

EDIT: debugonce() accomplishes the same without having to use undebug()

For anyone looking to use this and keep the 'click' functionality (as John Landheer mentions in his comment), you can do it with just a couple of modifications:

Add a couple of globals:

var clickms = 100;
var lastTouchDown = -1;

Then modify the switch statement from the original to this:

var d = new Date();
switch(event.type)
{
    case "touchstart": type = "mousedown"; lastTouchDown = d.getTime(); break;
    case "touchmove": type="mousemove"; lastTouchDown = -1; break;        
    case "touchend": if(lastTouchDown > -1 && (d.getTime() - lastTouchDown) < clickms){lastTouchDown = -1; type="click"; break;} type="mouseup"; break;
    default: return;
}

You may want to adjust 'clickms' to your tastes. Basically it's just watching for a 'touchstart' followed quickly by a 'touchend' to simulate a click.

The phantom comments, adding // where you want new lines, are great!

1. The @formatter: off adds a reference from the code to the editor. The code should, in my opinion, never have such references.

2. The phantom comments (//) will work regardless of the formatting tool used. Regardless of Eclipse or InteliJ or whatever editor you use. This even works with the very nice Google Java Format

3. The phantom comments (//) will work all over your application. If you also have Javascript and perhaps use something like JSBeautifier. You can have similar code style also in the Javascript.

4. Actually, you probably DO want formatting right? You want to remove mixed tab/space and trailing spaces. You want to indent the lines according to the code standard. What you DONT want is a long line. That, and only that, is what the phantom comment gives you!

I would like just to add that if you want to use windows socket library you have to :

• at the beginning : call WSAStartup()

• at the end : call WSACleanup()

$today_at_midnight = strtotime(date("Ymd"));

should give you what you're after.

explanation

What I did was use PHP's date function to get today's date without any references to time, and then pass it to the 'string to time' function which converts a date and time to a epoch timestamp. If it doesn't get a time, it assumes the first second of that day.

References: Date Function: http://php.net/manual/en/function.date.php

String To Time: http://us2.php.net/manual/en/function.strtotime.php

For us, everything was fine, emails are very small and not a lot of them are sent and sudently it gave this error. It appeared that a technicien installed ASTARO which was preventing email to be sent. and we were getting this error so yes the error is a bit cryptic but I hope this could help others.

Your regexp seems to validate both the file name and the extension. Is that what you need? I'll assume it's just the extension and would use a regexp like this:

\.(jpg|gif|doc|pdf)$

And set the matching to be case insensitive.

This probably harks from the old VB NOT .Net days when bool.ToString produced True or False.

python3 -m ensurepip

I'm not sure when exactly this was introduced, but it's installed pip3 for me when it didn't already exist.

git commit is nothing but saving our changes officially, for every commit we give commit message, once we are done with commits we can push it to remote to see our change globally

which means we can do numerous commits before we push to remote (we can see the list of commits happened and the messages too) git saves each commit with commit id which is a 40 digit code

and I use git push only when i wanted to see my change in remote (There after i will check whether my code worked in jenkins)

Depending on your URL scheme, you can make the UTF-8 encoded part "not important". For example, if you look at Stack Overflow URLs, they're of the following form:

http://stackoverflow.com/questions/2742852/unicode-characters-in-urls

However, the server doesn't actually care if you get the part after the identifier wrong, so this also works:

http://stackoverflow.com/questions/2742852/?????????????????

So if you had a layout like this, then you could potentially use UTF-8 in the part after the identifier and it wouldn't really matter if it got garbled. Of course this probably only works in somewhat specialised circumstances...

You can specify properties according profiles in one application.properties(yml) like here. Then mvn clean spring-boot:run -Dspring.profiles.active=dev should run it correct. It works for me

This validates dd/mm/yyy dates. Edit your jquery.validate.js and add these.

Reference(Regex): Regex to validate date format dd/mm/yyyy

    return this.optional(element) || /^(?:(?:31(\/|-|\.)(?:0?[13578]|1[02]))\1|(?:(?:29|30)(\/|-|\.)(?:0?[1,3-9]|1[0-2])\2))(?:(?:1[6-9]|[2-9]\d)?\d{2})$|^(?:29(\/|-|\.)0?2\3(?:(?:(?:1[6-9]|[2-9]\d)?(?:0[48]|[2468][048]|[13579][26])|(?:(?:16|[2468][048]|[3579][26])00))))$|^(?:0?[1-9]|1\d|2[0-8])(\/|-|\.)(?:(?:0?[1-9])|(?:1[0-2]))\4(?:(?:1[6-9]|[2-9]\d)?\d{2})$/.test(value);
}

messages: {
    dateBR: "Invalid date."
}

classRuleSettings: {
    dateBR: {dateBR: true}

Usage:

            dateBR: true
        }

This may not be as slick as a one-liner, but I use it to perform date manipulation mainly for reports:

DECLARE @Date datetime
SET @Date = GETDATE()

-- Set all time components to zero
SET @Date = DATEADD(ms, -DATEPART(ms, @Date), @Date) -- milliseconds = 0
SET @Date = DATEADD(ss, -DATEPART(ss, @Date), @Date) -- seconds = 0
SET @Date = DATEADD(mi, -DATEPART(mi, @Date), @Date) -- minutes = 0
SET @Date = DATEADD(hh, -DATEPART(hh, @Date), @Date) -- hours = 0

-- Extra manipulation for month and year
SET @Date = DATEADD(dd, -DATEPART(dd, @Date) + 1, @Date) -- day = 1
SET @Date = DATEADD(mm, -DATEPART(mm, @Date) + 1, @Date) -- month = 1

I use this to get hourly, daily, monthly, and yearly dates used for reporting and performance indicators, etc.

There is another solution.

Implement IFormatProvider to return a ICustomFormatter that will be passed to string.Format :

public class StringPadder : ICustomFormatter
{
  public string Format(string format, object arg,
       IFormatProvider formatProvider)
  {
     // do padding for string arguments
     // use default for others
  }
}

public class StringPadderFormatProvider : IFormatProvider
{
  public object GetFormat(Type formatType)
  { 
     if (formatType == typeof(ICustomFormatter))
        return new StringPadder();

     return null;
  }
  public static readonly IFormatProvider Default =
     new StringPadderFormatProvider();
}

Then you can use it like this :

string.Format(StringPadderFormatProvider.Default, "->{0:x20}<-", "Hello");

The String#replaceAll() interprets the argument as a regular expression. The \ is an escape character in both String and regex. You need to double-escape it for regex:

string.replaceAll("\\\\", "\\\\\\\\");

But you don't necessarily need regex for this, simply because you want an exact character-by-character replacement and you don't need patterns here. So String#replace() should suffice:

string.replace("\\", "\\\\");

Update: as per the comments, you appear to want to use the string in JavaScript context. You'd perhaps better use StringEscapeUtils#escapeEcmaScript() instead to cover more characters.

You are correct in that static files are copied to the application at link-time, and that shared files are just verified at link time and loaded at runtime.

The dlopen call is not only for shared objects, if the application wishes to do so at runtime on its behalf, otherwise the shared objects are loaded automatically when the application starts. DLLS and .so are the same thing. the dlopen exists to add even more fine-grained dynamic loading abilities for processes. You dont have to use dlopen yourself to open/use the DLLs, that happens too at application startup.

Use HH for 24 hour hours format:

DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss")

Or the tt format specifier for the AM/PM part:

DateTime.Now.ToString("yyyy-MM-dd hh:mm:ss tt")

Take a look at the custom Date and Time format strings documentation.

You can use this code, this code is for AES-256-CBC or you can use it for other AES encryption. Key length error mainly comes in 256-bit encryption.

This error comes due to the encoding or charset name we pass in the SecretKeySpec. Suppose, in my case, I have a key length of 44, but I am not able to encrypt my text using this long key; Java throws me an error of invalid key length. Therefore I pass my key as a BASE64 in the function, and it converts my 44 length key in the 32 bytes, which is must for the 256-bit encryption.

import javax.crypto.Cipher;
import javax.crypto.spec.IvParameterSpec;
import javax.crypto.spec.SecretKeySpec;
import java.security.MessageDigest;
import java.security.Security;
import java.util.Base64;

public class Encrypt {

    static byte [] arr = {1,2,3,4,5,6,7,8,9};

    // static byte [] arr = new byte[16];

      public static void main(String...args) {
        try {
         //   System.out.println(Cipher.getMaxAllowedKeyLength("AES"));
            Base64.Decoder decoder = Base64.getDecoder();
            // static byte [] arr = new byte[16];
            Security.setProperty("crypto.policy", "unlimited");
            String key = "Your key";
       //     System.out.println("-------" + key);

            String value = "Hey, i am adnan";
            String IV = "0123456789abcdef";
       //     System.out.println(value);
            // log.info(value);
          IvParameterSpec iv = new IvParameterSpec(IV.getBytes());
            //    IvParameterSpec iv = new IvParameterSpec(arr);

        //    System.out.println(key);
            SecretKeySpec skeySpec = new SecretKeySpec(decoder.decode(key), "AES");
         //   System.out.println(skeySpec);
            Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
        //    System.out.println("ddddddddd"+IV);
            cipher.init(Cipher.ENCRYPT_MODE, skeySpec, iv);
       //     System.out.println(cipher.getIV());

            byte[] encrypted = cipher.doFinal(value.getBytes());
            String encryptedString = Base64.getEncoder().encodeToString(encrypted);

            System.out.println("encrypted string,,,,,,,,,,,,,,,,,,,: " + encryptedString);
            // vars.put("input-1",encryptedString);
            //  log.info("beanshell");
        }catch (Exception e){
            System.out.println(e.getMessage());
        }
    }
}

I don't understand where the first "result with sample data" is coming from, but the problem in the console app is that you're using SelectMany to look at each item in each group.

I think you just want:

List<ResultLine> result = Lines
    .GroupBy(l => l.ProductCode)
    .Select(cl => new ResultLine
            {
                ProductName = cl.First().Name,
                Quantity = cl.Count().ToString(),
                Price = cl.Sum(c => c.Price).ToString(),
            }).ToList();

The use of First() here to get the product name assumes that every product with the same product code has the same product name. As noted in comments, you could group by product name as well as product code, which will give the same results if the name is always the same for any given code, but apparently generates better SQL in EF.

I'd also suggest that you should change the Quantity and Price properties to be int and decimal types respectively - why use a string property for data which is clearly not textual?

$newstr = substr_replace($oldstr, $str_to_insert, $pos, 0);

Bash has built in features to access the last command executed. But that's the last whole command (e.g. the whole case command), not individual simple commands like you originally requested.

!:0 = the name of command executed.

!:1 = the first parameter of the previous command

!:* = all of the parameters of the previous command

!:-1 = the final parameter of the previous command

!! = the previous command line

etc.

So, the simplest answer to the question is, in fact:

echo !!

...alternatively:

echo "Last command run was ["!:0"] with arguments ["!:*"]"

Try it yourself!

echo this is a test

For the one shot solution I have found this tool that does the job: https://www.npmjs.com/package/junit-viewer

junit-viewer --results=surefire-reports --save=file_location.html

--results= is directory with xml files (test reports)

Ctrl+Alt+Down Copies current line to below like notepad++ (Ctrl+D)

If your whole screen is 180° rotted then you should disable your hotkey settings.

Right Click -> Graphics Options -> Hot Keys -> Disable

That it now you done try shortcut Ctrl+Alt+Down

You can take a look at this article. It makes use of registry to read the list of installed applications.

public void GetInstalledApps()
{
    string uninstallKey = @"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall";
    using (RegistryKey rk = Registry.LocalMachine.OpenSubKey(uninstallKey))
    {
        foreach (string skName in rk.GetSubKeyNames())
        {
            using (RegistryKey sk = rk.OpenSubKey(skName))
            {
                try
                {
                    lstInstalled.Items.Add(sk.GetValue("DisplayName"));
                }
                catch (Exception ex)
                { }
            }
        }
    }
}

"$env:computername.$env:userdnsdomain" 

will work if separated out like this

"$env:computername"+"$env:userdnsdomain"

You can calculate the offset of the element and then compare that with the scroll value like:

$(window).scroll(function() {
   var hT = $('#scroll-to').offset().top,
       hH = $('#scroll-to').outerHeight(),
       wH = $(window).height(),
       wS = $(this).scrollTop();
   if (wS > (hT+hH-wH)){
       console.log('H1 on the view!');
   }
});

Check this Demo Fiddle

Updated Demo Fiddle no alert -- instead FadeIn() the element

Updated code to check if the element is inside the viewport or not. Thus this works whether you are scrolling up or down adding some rules to the if statement:

   if (wS > (hT+hH-wH) && (hT > wS) && (wS+wH > hT+hH)){
       //Do something
   }

Demo Fiddle

Use Location property of the form. Set it to the desired top left point

desired x = (desktop_width - form_witdh)/2

desired y = (desktop_height - from_height)/2

Try this code. You get android device name.

public static String getDeviceName() {
    String manufacturer = Build.MANUFACTURER;
    String model = Build.MODEL;
    if (model.startsWith(manufacturer)) {
        return model;
    }
    return manufacturer + " " + model;
}

How about?

<?php
   $queried_post = get_page_by_path('my_slug',OBJECT,'post');
?>

Check you have the line:

 import org.json.JSONArray;

at the top of your source code

Minted, whether from GitHub or CTAN, the Comprehensive TeX Archive Network, works in Overleaf, TeX Live and MiKTeX.

It requires the installation of the Python package Pygments; this is explained in the documentation in either source above. Although Pygments brands itself as a Python syntax highlighter, Minted guarantees the coverage of hundreds of other languages.

Example:

\documentclass{article}
\usepackage{minted}
\begin{document}

\begin{minted}[mathescape, linenos]{python}

# Note: $\pi=\lim_{n\to\infty}\frac{P_n}{d}$
title = "Hello World"

sum = 0
for i in range(10):
 sum += i

\end{minted}

\end{document}

I used just the lines below and it worked. I just wanted to compile VirtualBox and VMWare WorkStation using kernel 4.8.10 on Ubuntu 14.04. Initially, most things were not working for example graphics and networking. I was lucky that VMWare workstation requested for gcc 6.2.0. I couldn't start my Genymotion Android emulators because virtualbox was down. Will post results later if necessary.

The OSIV Anti-Pattern

Instead of letting the business layer decide how it’s best to fetch all the associations that are needed by the View layer, OSIV (Open Session in View) forces the Persistence Context to stay open so that the View layer can trigger the Proxy initialization, as illustrated by the following diagram.

• The OpenSessionInViewFilter calls the openSession method of the underlying SessionFactory and obtains a new Session.
• The Session is bound to the TransactionSynchronizationManager.
• The OpenSessionInViewFilter calls the doFilter of the javax.servlet.FilterChain object reference and the request is further processed
• The DispatcherServlet is called, and it routes the HTTP request to the underlying PostController.
• The PostController calls the PostService to get a list of Post entities.
• The PostService opens a new transaction, and the HibernateTransactionManager reuses the same Session that was opened by the OpenSessionInViewFilter.
• The PostDAO fetches the list of Post entities without initializing any lazy association.
• The PostService commits the underlying transaction, but the Session is not closed because it was opened externally.
• The DispatcherServlet starts rendering the UI, which, in turn, navigates the lazy associations and triggers their initialization.
• The OpenSessionInViewFilter can close the Session, and the underlying database connection is released as well.

At first glance, this might not look like a terrible thing to do, but, once you view it from a database perspective, a series of flaws start to become more obvious.

The service layer opens and closes a database transaction, but afterward, there is no explicit transaction going on. For this reason, every additional statement issued from the UI rendering phase is executed in auto-commit mode. Auto-commit puts pressure on the database server because each transaction issues a commit at end, which can trigger a transaction log flush to disk. One optimization would be to mark the Connection as read-only which would allow the database server to avoid writing to the transaction log.

There is no separation of concerns anymore because statements are generated both by the service layer and by the UI rendering process. Writing integration tests that assert the number of statements being generated requires going through all layers (web, service, DAO) while having the application deployed on a web container. Even when using an in-memory database (e.g. HSQLDB) and a lightweight webserver (e.g. Jetty), these integration tests are going to be slower to execute than if layers were separated and the back-end integration tests used the database, while the front-end integration tests were mocking the service layer altogether.

The UI layer is limited to navigating associations which can, in turn, trigger N+1 query problems. Although Hibernate offers @BatchSize for fetching associations in batches, and FetchMode.SUBSELECT to cope with this scenario, the annotations are affecting the default fetch plan, so they get applied to every business use case. For this reason, a data access layer query is much more suitable because it can be tailored to the current use case data fetch requirements.

Last but not least, the database connection is held throughout the UI rendering phase which increases connection lease time and limits the overall transaction throughput due to congestion on the database connection pool. The more the connection is held, the more other concurrent requests are going to wait to get a connection from the pool.

Spring Boot and OSIV

Unfortunately, OSIV (Open Session in View) is enabled by default in Spring Boot, and OSIV is really a bad idea from a performance and scalability perspective.

So, make sure that in the application.properties configuration file, you have the following entry:

spring.jpa.open-in-view=false

This will disable OSIV so that you can handle the LazyInitializationException the right way.

Starting with version 2.0, Spring Boot issues a warning when OSIV is enabled by default, so you can discover this problem long before it affects a production system.

You can try to use the following code instead:

 $pro= model_name::where('col_name', '=', 'value')->get();

You use the String.format() method.

From Overview of Numeric Types;

BIT[(M)]

A bit-field type. M indicates the number of bits per value, from 1 to 64. The default is 1 if M is omitted.

This data type was added in MySQL 5.0.3 for MyISAM, and extended in 5.0.5 to MEMORY, InnoDB, BDB, and NDBCLUSTER. Before 5.0.3, BIT is a synonym for TINYINT(1).

TINYINT[(M)] [UNSIGNED] [ZEROFILL]

A very small integer. The signed range is -128 to 127. The unsigned range is 0 to 255.

Additionally consider this;

BOOL, BOOLEAN

These types are synonyms for TINYINT(1). A value of zero is considered false. Non-zero values are considered true.

None of these anwers worked for me, I found Werner Bihl's answer that fixed the problem.

Where do these values come from? The documentation for android:fontFamily does not list this information in any place

These are indeed not listed in the documentation. But they are mentioned here under the section 'Font families'. The document lists every new public API for Android Jelly Bean 4.1.

In the styles.xml file in the application I'm working on somebody listed this as the font family, and I'm pretty sure it's wrong:

Yes, that's wrong. You don't reference the font file, you have to use the font name mentioned in the linked document above. In this case it should have been this:

<item name="android:fontFamily">sans-serif</item>

Like the linked answer already stated, 12 variants are possible:

Added in Android Jelly Bean (4.1) - API 16 :

Regular (default):

<item name="android:fontFamily">sans-serif</item>
<item name="android:textStyle">normal</item> 

Italic:

<item name="android:fontFamily">sans-serif</item>
<item name="android:textStyle">italic</item>

Bold:

<item name="android:fontFamily">sans-serif</item>
<item name="android:textStyle">bold</item>

Bold-italic:

<item name="android:fontFamily">sans-serif</item>
<item name="android:textStyle">bold|italic</item>

Light:

<item name="android:fontFamily">sans-serif-light</item>
<item name="android:textStyle">normal</item>

Light-italic:

<item name="android:fontFamily">sans-serif-light</item>
<item name="android:textStyle">italic</item>

Thin :

<item name="android:fontFamily">sans-serif-thin</item>
<item name="android:textStyle">normal</item>

Thin-italic :

<item name="android:textStyle">italic</item>

Condensed regular:

<item name="android:fontFamily">sans-serif-condensed</item>
<item name="android:textStyle">normal</item>

Condensed italic:

<item name="android:fontFamily">sans-serif-condensed</item>
<item name="android:textStyle">italic</item>

Condensed bold:

<item name="android:textStyle">bold</item>

Condensed bold-italic:

<item name="android:fontFamily">sans-serif-condensed</item>
<item name="android:textStyle">bold|italic</item>

Added in Android Lollipop (v5.0) - API 21 :

Medium:

<item name="android:fontFamily">sans-serif-medium</item>
<item name="android:textStyle">normal</item>

Medium-italic:

<item name="android:fontFamily">sans-serif-medium</item>
<item name="android:textStyle">italic</item>

Black:

<item name="android:fontFamily">sans-serif-black</item>
<item name="android:textStyle">italic</item>

For quick reference, this is how they all look like:

As you use Joda Time, you should use DateTimeFormatter:

final DateTimeFormatter dtf = DateTimeFormatter.ofPattern("yyyy-MMM-dd");
final LocalDate dt = dtf.parseLocalDate(yourinput);

If using Java 8 or later, then refer to hertzi's answer

Eclipse Juno, Indigo and Kepler when using the bundled maven version(m2e), are not suppressing the message SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder". This behaviour is present from the m2e version 1.1.0.20120530-0009 and onwards.

Although, this is indicated as an error your logs will be saved normally. The highlighted error will still be present until there is a fix of this bug. More about this in the m2e support site.

The current available solution is to use an external maven version rather than the bundled version of Eclipse. You can find about this solution and more details regarding this bug in the question below which i believe describes the same problem you are facing.

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder". error

The below code works fine but I am not sure about the radio button and dropdown list

$( '#form_id' ).submit( function( event ) {
    event.preventDefault();

    //validate fields
    var fail = false;
    var fail_log = '';
    var name;
    $( '#form_id' ).find( 'select, textarea, input' ).each(function(){
        if( ! $( this ).prop( 'required' )){

        } else {
            if ( ! $( this ).val() ) {
                fail = true;
                name = $( this ).attr( 'name' );
                fail_log += name + " is required \n";
            }

        }
    });

    //submit if fail never got set to true
    if ( ! fail ) {
        //process form here.
    } else {
        alert( fail_log );
    }

});

You should use something ([ngClass] instead of *ngClass) like that:

<ol class="breadcrumb">
  <li [ngClass]="{active: step==='step1'}" (click)="step='step1; '">Step1</li>
  (...)

I haven't used connect by prior, but a quick search shows it's used for tree structures. In SQL Server, you use common table expressions to get similar functionality.

Java FX has Media and MediaPlayer classes which will play mp3 files.

Example code:

String bip = "bip.mp3";
Media hit = new Media(new File(bip).toURI().toString());
MediaPlayer mediaPlayer = new MediaPlayer(hit);
mediaPlayer.play();

You will need the following import statements:

import java.io.File;
import javafx.scene.media.Media;
import javafx.scene.media.MediaPlayer;

We had this in many other cases, what we decided internally is to always have a wrapper for the controller/directive so that we don't need to think about it. Here is you example with our wrapper.

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.0rc1/angular.min.js"></script>

<script>
    function main($scope) {
        $scope.thisScope = $scope;
        $scope.testa = false;
        $scope.testb = false;
        $scope.testc = false;
        $scope.testd = false;
    }
</script>

<div ng-app >
    <div ng-controller="main">

        Test A: {{testa}}<br />
        Test B: {{testb}}<br />
        Test C: {{testc}}<br />
        Test D: {{testd}}<br />

        <div>
            testa (without ng-if): <input type="checkbox" ng-model="thisScope.testa" />
        </div>
        <div ng-if="!testa">
            testb (with ng-if): <input type="checkbox" ng-model="thisScope.testb" />
        </div>
        <div ng-show="!testa">
            testc (with ng-show): <input type="checkbox" ng-model="thisScope.testc" />
        </div>
        <div ng-hide="testa">
            testd (with ng-hide): <input type="checkbox" ng-model="thisScope.testd" />
        </div>

    </div>

While you can't directly recover a MySQL password without bruteforcing, there might be another way - if you've used MySQL Workbench to connect to the database, and have saved the credentials to the "vault", you're golden.

On Windows, the credentials are stored in %APPDATA%\MySQL\Workbench\workbench_user_data.dat - encrypted with CryptProtectData (without any additional entropy). Decrypting is easy peasy:

std::vector<unsigned char> decrypt(BYTE *input, size_t length) {
    DATA_BLOB inblob { length, input };
    DATA_BLOB outblob;

    if (!CryptUnprotectData(&inblob, NULL, NULL, NULL, NULL, CRYPTPROTECT_UI_FORBIDDEN, &outblob)) {
            throw std::runtime_error("Couldn't decrypt");
    }

    std::vector<unsigned char> output(length);
    memcpy(&output[0], outblob.pbData, outblob.cbData);

    return output;
}

Setting a -vendor prefix that isn't supported in older browsers can cause them to throw an exception with .css. Instead detect the supported prefix first:

// Start with a fall back
var newCss = { 'zoom' : ui.value };

// Replace with transform, if supported
if('WebkitTransform' in document.body.style) 
{
    newCss = { '-webkit-transform': 'scale(' + ui.value + ')'};
}
// repeat for supported browsers
else if('transform' in document.body.style) 
{
    newCss = { 'transform': 'scale(' + ui.value + ')'};
}

// Set the CSS
$('.user-text').css(newCss)

That works in old browsers. I've done scale here but you could replace it with whatever other transform you wanted.

I wrote once a tool for myself to do exactly that thing:

After hours of research, I finally found a solution to take a screenshot of an element, even if the origin-clean FLAG is set (to prevent XSS), that´s why you can even capture for example Google Maps (in my case). I wrote a universal function to get a screenshot. The only thing you need in addition is the html2canvas library (https://html2canvas.hertzen.com/).

Example:

getScreenshotOfElement($("div#toBeCaptured").get(0), 0, 0, 100, 100, function(data) {
    // in the data variable there is the base64 image
    // exmaple for displaying the image in an <img>
    $("img#captured").attr("src", "data:image/png;base64,"+data);
});

Keep in mind console.log() and alert() won´t generate output if the size of the image is great.

Function:

function getScreenshotOfElement(element, posX, posY, width, height, callback) {
    html2canvas(element, {
        onrendered: function (canvas) {
            var context = canvas.getContext('2d');
            var imageData = context.getImageData(posX, posY, width, height).data;
            var outputCanvas = document.createElement('canvas');
            var outputContext = outputCanvas.getContext('2d');
            outputCanvas.width = width;
            outputCanvas.height = height;

            var idata = outputContext.createImageData(width, height);
            idata.data.set(imageData);
            outputContext.putImageData(idata, 0, 0);
            callback(outputCanvas.toDataURL().replace("data:image/png;base64,", ""));
        },
        width: width,
        height: height,
        useCORS: true,
        taintTest: false,
        allowTaint: false
    });
}

If you want a simple code to put on other location, take this:

using IWshRuntimeLibrary;

WshShell shell = new WshShell();
IWshShortcut shortcut = shell.CreateShortcut(@"C:\FOLDER\SOFTWARENAME.lnk");
shortcut.TargetPath = @"C:\FOLDER\SOFTWARE.exe";
shortcut.Save();

This is how I mange to get (as currently there is no direct support- in future it will be for sure) python 3.9 in anaconda and windows 10
Note: I needed extra packages so install them, install only what you need

conda create --name e39 python=3.9 --channel conda-forge

320

And the segments look like this

{64}@{255}

64 + 1 + 255 = 320

@Patrick To sort more than one field consecutively try ComparatorChain

A ComparatorChain is a Comparator that wraps one or more Comparators in sequence. The ComparatorChain calls each Comparator in sequence until either 1) any single Comparator returns a non-zero result (and that result is then returned), or 2) the ComparatorChain is exhausted (and zero is returned). This type of sorting is very similar to multi-column sorting in SQL, and this class allows Java classes to emulate that kind of behaviour when sorting a List.

To further facilitate SQL-like sorting, the order of any single Comparator in the list can >be reversed.

Calling a method that adds new Comparators or changes the ascend/descend sort after compare(Object, Object) has been called will result in an UnsupportedOperationException. However, take care to not alter the underlying List of Comparators or the BitSet that defines the sort order.

Instances of ComparatorChain are not synchronized. The class is not thread-safe at construction time, but it is thread-safe to perform multiple comparisons after all the setup operations are complete.

How about using a grid? it's 2019 and support is reasonable

After you write to the MemoryStream and before you read it back, you need to Seek back to the beginning of the MemoryStream so you're not reading from the end.

UPDATE

After seeing your update, I think there's a more reliable way to build the stream:

UnicodeEncoding uniEncoding = new UnicodeEncoding();
String message = "Message";

// You might not want to use the outer using statement that I have
// I wasn't sure how long you would need the MemoryStream object    
using(MemoryStream ms = new MemoryStream())
{
    var sw = new StreamWriter(ms, uniEncoding);
    try
    {
        sw.Write(message);
        sw.Flush();//otherwise you are risking empty stream
        ms.Seek(0, SeekOrigin.Begin);

        // Test and work with the stream here. 
        // If you need to start back at the beginning, be sure to Seek again.
    }
    finally
    {
        sw.Dispose();
    }
}

As you can see, this code uses a StreamWriter to write the entire string (with proper encoding) out to the MemoryStream. This takes the hassle out of ensuring the entire byte array for the string is written.

Update: I stepped into issue with empty stream several time. It's enough to call Flush right after you've finished writing.

The problem is that the regex pattern is being HTML encoded twice, once when the regex is being built, and once when being rendered in your view.

For now, try wrapping your TextBoxFor in an Html.Raw, like so:

@Html.Raw(Html.TextBoxFor(model => Model.FirstName, new { }))

You can animate it after the fadeIn completes using the callback as shown below:

$("#Friends").fadeIn('slow',function(){
  $(this).animate({'top': '-=30px'},'slow');
});

Plain and simple:

plt.plot(x, y, 'r-', alpha=0.7)

(I know I add nothing new, but the straightforward answer should be visible).

use these functions

    public static int getDateDifference(int previousYear, int previousMonthOfYear, int previousDayOfMonth, int nextYear, int nextMonthOfYear, int nextDayOfMonth, int differenceToCount){
    // int differenceToCount = can be any of the following
    //  Calendar.MILLISECOND;
    //  Calendar.SECOND;
    //  Calendar.MINUTE;
    //  Calendar.HOUR;
    //  Calendar.DAY_OF_MONTH;
    //  Calendar.MONTH;
    //  Calendar.YEAR;
    //  Calendar.----

    Calendar previousDate = Calendar.getInstance();
    previousDate.set(Calendar.DAY_OF_MONTH, previousDayOfMonth);
    // month is zero indexed so month should be minus 1
    previousDate.set(Calendar.MONTH, previousMonthOfYear);
    previousDate.set(Calendar.YEAR, previousYear);

    Calendar nextDate = Calendar.getInstance();
    nextDate.set(Calendar.DAY_OF_MONTH, previousDayOfMonth);
    // month is zero indexed so month should be minus 1
    nextDate.set(Calendar.MONTH, previousMonthOfYear);
    nextDate.set(Calendar.YEAR, previousYear);

    return getDateDifference(previousDate,nextDate,differenceToCount);
}
public static int getDateDifference(Calendar previousDate,Calendar nextDate,int differenceToCount){
    // int differenceToCount = can be any of the following
    //  Calendar.MILLISECOND;
    //  Calendar.SECOND;
    //  Calendar.MINUTE;
    //  Calendar.HOUR;
    //  Calendar.DAY_OF_MONTH;
    //  Calendar.MONTH;
    //  Calendar.YEAR;
    //  Calendar.----

    //raise an exception if previous is greater than nextdate.
    if(previousDate.compareTo(nextDate)>0){
        throw new RuntimeException("Previous Date is later than Nextdate");
    }

    int difference=0;
    while(previousDate.compareTo(nextDate)<=0){
        difference++;
        previousDate.add(differenceToCount,1);
    }
    return difference;
}

Since this is a common piece of functionality it's a good idea to write a directive for this. In fact, someone already did that and open sourced it. I used editablespan library in one of my projects and it worked perfectly, highly recommended.

The best way is

AddTaskViewController * add = [self.storyboard instantiateViewControllerWithIdentifier:@"addID"];
[self presentViewController:add animated:YES completion:nil];

You can look at the target of the mouseover event on some suitable ancestor:

var currentElement = null;

document.addEventListener('mouseover', function (e) {
    currentElement = e.target;
});

Here’s a demo.

A fun, simple solution:

for (int i = 0; i < 5; i++) 
  System.out.println("    *********".substring(i, 5 + 2*i));

This is an extension to BigJim's brilliant answer.

In my case I had a NodeBase class with a Children dictionary, and I needed a way to generically do O(1) lookups from the children. I was attempting to return a private dictionary field in the getter of Children, so obviously I wanted to avoid expensive copying/iterating. Therefore I used Bigjim's code to cast the Dictionary<whatever specific type> to a generic Dictionary<NodeBase>:

// Abstract parent class
public abstract class NodeBase
{
    public abstract IDictionary<string, NodeBase> Children { get; }
    ...
}

// Implementing child class
public class RealNode : NodeBase
{
    private Dictionary<string, RealNode> containedNodes;

    public override IDictionary<string, NodeBase> Children
    {
        // Using a modification of Bigjim's code to cast the Dictionary:
        return new IDictionary<string, NodeBase>().CastDictionary<string, RealNode, NodeBase>();
    }
    ...
}

This worked well. However, I eventually ran into unrelated limitations and ended up creating an abstract FindChild() method in the base class that would do the lookups instead. As it turned out this eliminated the need for the casted dictionary in the first place. (I was able to replace it with a simple IEnumerable for my purposes.)

So the question you might ask (especially if performance is an issue prohibiting you from using .Cast<> or .ConvertAll<>) is:

"Do I really need to cast the entire collection, or can I use an abstract method to hold the special knowledge needed to perform the task and thereby avoid directly accessing the collection?"

Sometimes the simplest solution is the best.

There are two distinct uses of mipmaps:

1. For launcher icons when building density specific APKs. Some developers build separate APKs for every density, to keep the APK size down. However some launchers (shipped with some devices, or available on the Play Store) use larger icon sizes than the standard 48dp. Launchers use getDrawableForDensity and scale down if needed, rather than up, so the icons are high quality. For example on an hdpi tablet the launcher might load the xhdpi icon. By placing your launcher icon in the mipmap-xhdpi directory, it will not be stripped the way a drawable-xhdpi directory is when building an APK for hdpi devices. If you're building a single APK for all devices, then this doesn't really matter as the launcher can access the drawable resources for the desired density.

2. The actual mipmap API from 4.3. I haven't used this and am not familiar with it. It's not used by the Android Open Source Project launchers and I'm not aware of any other launcher using.

You can use:

  import ipy_autoreload
  %autoreload 2 
  %aimport your_mod

another way is to provide no cache headers from serverside in the code that generates the response to ajax call:

response.setHeader( "Pragma", "no-cache" );
response.setHeader( "Cache-Control", "no-cache" );
response.setDateHeader( "Expires", 0 );

What is wrong with List.Find ??

I think we need more information on what you've done, and why it fails, before we can provide truly helpful answers.

This works for me in Ansible 2.9:

variable1 = www.example.com. 
variable2 = www.example.org. 

when: ".com" in variable1

and for not:

when: not ".com" in variable2

I refined the bash solution a bit, so that the more efficient scan is used instead of keys, and printing out array and hash values is supported. My solution also prints out the key name.

redis_print.sh:

#!/bin/bash

# Default to '*' key pattern, meaning all redis keys in the namespace
REDIS_KEY_PATTERN="${REDIS_KEY_PATTERN:-*}"
for key in $(redis-cli --scan --pattern "$REDIS_KEY_PATTERN")
do
    type=$(redis-cli type $key)
    if [ $type = "list" ]
    then
        printf "$key => \n$(redis-cli lrange $key 0 -1 | sed 's/^/  /')\n"
    elif [ $type = "hash" ]
    then
        printf "$key => \n$(redis-cli hgetall $key | sed 's/^/  /')\n"
    else
        printf "$key => $(redis-cli get $key)\n"
    fi
done

Note: you can formulate a one-liner of this script by removing the first line of redis_print.sh and commanding: cat redis_print.sh | tr '\n' ';' | awk '$1=$1'

If you are sure that the modification in the SQL file has no impact on your existing schema, you can also update the checksum of the existing schema.

I did this following a slight change in the sql file.

Here is how I updated the checksum:

update flyway_schema_history set checksum = '-1934991199' where installed_rank = '1';

Yet another solution.

Add ErrorControllers or static page to with 404 error information.

Modify your web.config (in case of controller).

<system.web>
    <customErrors mode="On" >
       <error statusCode="404" redirect="~/Errors/Error404" />
    </customErrors>
</system.web>

Or in case of static page

<system.web>
    <customErrors mode="On" >
        <error statusCode="404" redirect="~/Static404.html" />
    </customErrors>
</system.web>

This will handle both missed routes and missed actions.

The "official" way to get the vs2015 is to go to https://my.visualstudio.com/ ; join the " Visual Studio Dev Essentials" and then search the relevant file to download https://my.visualstudio.com/Downloads?q=Visual%20Studio%202015%20with%20Update%203

You are setting the ScaleType to ScaleType.FIT_XY. According to the javadocs, this will stretch the image to fit the whole area, changing the aspect ratio if necessary. That would explain the behavior you are seeing.

To get the behavior you want... FIT_CENTER, FIT_START, or FIT_END are close, but if the image is narrower than it is tall, it will not start to fill the width. You could look at how those are implemented though, and you should probably be able to figure out how to adjust it for your purpose.

In JBoss Developer 4.0 and above (Eclipse-based), this is a tad easier. Just right-click on your file or folder that contains xml-based files, choose "Exclude Validation", then click "Yes" to confirm. Then right-click the same files/folder again and click on "Validate", which will remove the errors with a confirmation.

This is not another code as you have already helped yourself; but for you to take a look at the performance when using Excel functions in VBA.

• Match() is faster for smaller number of search, but it isn't when it compared to a large number of data. And in that instance you may consider a variant array/dictionary/arrayList approach depending on if you want to sort, you want to have duplicates or not..

• Error handling on Match

PS: **On a latter note, if you wish to do pattern matching then you may consider ScriptingObject **Regex.

An idea using reflection:

class ViewModelBase : INotifyPropertyChanged {

    public event PropertyChangedEventHandler PropertyChanged;

    bool Notify<T>(MethodBase mb, ref T oldValue, T newValue) {

        // Get Name of Property
        string name = mb.Name.Substring(4);

        // Detect Change
        bool changed = EqualityComparer<T>.Default.Equals(oldValue, newValue);

        // Return if no change
        if (!changed) return false;

        // Update value
        oldValue = newValue;

        // Raise Event
        if (PropertyChanged != null) {
            PropertyChanged(this, new PropertyChangedEventArgs(name));
        }//if

        // Notify caller of change
        return true;

    }//method

    string name;

    public string Name {
        get { return name; }
        set {
            Notify(MethodInfo.GetCurrentMethod(), ref this.name, value);
        }
    }//method

}//class

Finally this worked for me

private String buildBasicAuthorizationString(String username, String password) {

    String credentials = username + ":" + password;
    return "Basic " + new String(Base64.encode(credentials.getBytes(), Base64.NO_WRAP));
}

Instead of using re.search use re.findall it will return you all matches in a List. Or you could also use re.finditer (which i like most to use) it will return an Iterator Object and you can just use it to iterate over all found matches.

line = 'bla bla bla<form>Form 1</form> some text...<form>Form 2</form> more text?'
for match in re.finditer('<form>(.*?)</form>', line, re.S):
    print match.group(1)

The top 2 answers (from Adam Robinson and Andrejs Cainikovs) are kinda, sorta correct, in that they do technically work, but their explanations are wrong and so could be misleading in many cases. For example, while the SQL_Latin1_General_CP1_CI_AS collation will work in many cases, it should not be assumed to be the appropriate case-insensitive collation. In fact, given that the O.P. is working in a database with a case-sensitive (or possibly binary) collation, we know that the O.P. isn't using the collation that is the default for so many installations (especially any installed on an OS using US English as the language): SQL_Latin1_General_CP1_CI_AS. Sure, the O.P. could be using SQL_Latin1_General_CP1_CS_AS, but when working with VARCHAR data, it is important to not change the code page as it could lead to data loss, and that is controlled by the locale / culture of the collation (i.e. Latin1_General vs French vs Hebrew etc). Please see point # 9 below.

The other four answers are wrong to varying degrees.

I will clarify all of the misunderstandings here so that readers can hopefully make the most appropriate / efficient choices.

1. Do not use UPPER(). That is completely unnecessary extra work. Use a COLLATE clause. A string comparison needs to be done in either case, but using UPPER() also has to check, character by character, to see if there is an upper-case mapping, and then change it. And you need to do this on both sides. Adding COLLATE simply directs the processing to generate the sort keys using a different set of rules than it was going to by default. Using COLLATE is definitely more efficient (or "performant", if you like that word :) than using UPPER(), as proven in this test script (on PasteBin).

   There is also the issue noted by @Ceisc on @Danny's answer:

   In some languages case conversions do not round-trip. i.e. LOWER(x) != LOWER(UPPER(x)).

   The Turkish upper-case "I" is the common example.

2. No, collation is not a database-wide setting, at least not in this context. There is a database-level default collation, and it is used as the default for altered and newly created columns that do not specify the COLLATE clause (which is likely where this common misconception comes from), but it does not impact queries directly unless you are comparing string literals and variables to other string literals and variables, or you are referencing database-level meta-data.

3. No, collation is not per query.

4. Collations are per predicate (i.e. something operand something) or expression, not per query. And this is true for the entire query, not just the WHERE clause. This covers JOINs, GROUP BY, ORDER BY, PARTITION BY, etc.

5. No, do not convert to VARBINARY (e.g.convert(varbinary, myField) = convert(varbinary, 'sOmeVal')) for the following reasons:

   1. that is a binary comparison, which is not case-insensitive (which is what this question is asking for)
   2. if you do want a binary comparison, use a binary collation. Use one that ends with _BIN2 if you are using SQL Server 2008 or newer, else you have no choice but to use one that ends with _BIN. If the data is NVARCHAR then it doesn't matter which locale you use as they are all the same in that case, hence Latin1_General_100_BIN2 always works. If the data is VARCHAR, you must use the same locale that the data is currently in (e.g. Latin1_General, French, Japanese_XJIS, etc) because the locale determines the code page that is used, and changing code pages can alter the data (i.e. data loss).
   3. using a variable-length datatype without specifying the size will rely on the default size, and there are two different defaults depending on the context where the datatype is being used. It is either 1 or 30 for string types. When used with CONVERT() it will use the 30 default value. The danger is, if the string can be over 30 bytes, it will get silently truncated and you will likely get incorrect results from this predicate.
   4. Even if you want a case-sensitive comparison, binary collations are not case-sensitive (another very common misconception).

6. No, LIKE is not always case-sensitive. It uses the collation of the column being referenced, or the collation of the database if a variable is compared to a string literal, or the collation specified via the optional COLLATE clause.

7. LCASE is not a SQL Server function. It appears to be either Oracle or MySQL. Or possibly Visual Basic?

8. Since the context of the question is comparing a column to a string literal, neither the collation of the instance (often referred to as "server") nor the collation of the database have any direct impact here. Collations are stored per each column, and each column can have a different collation, and those collations don't need to be the same as the database's default collation or the instance's collation. Sure, the instance collation is the default for what a newly created database will use as its default collation if the COLLATE clause wasn't specified when creating the database. And likewise, the database's default collation is what an altered or newly created column will use if the COLLATE clause wasn't specified.

9. You should use the case-insensitive collation that is otherwise the same as the collation of the column. Use the following query to find the column's collation (change the table's name and schema name):

   SELECT col.*
   FROM   sys.columns col
   WHERE  col.[object_id] = OBJECT_ID(N'dbo.TableName')
   AND    col.[collation_name] IS NOT NULL;
   

   Then just change the _CS to be _CI. So, Latin1_General_100_CS_AS would become Latin1_General_100_CI_AS.

   If the column is using a binary collation (ending in _BIN or _BIN2), then find a similar collation using the following query:

   SELECT *
   FROM   sys.fn_helpcollations() col
   WHERE  col.[name] LIKE N'{CurrentCollationMinus"_BIN"}[_]CI[_]%';
   

   For example, assuming the column is using Japanese_XJIS_100_BIN2, do this:

   SELECT *
   FROM   sys.fn_helpcollations() col
   WHERE  col.[name] LIKE N'Japanese_XJIS_100[_]CI[_]%';
   

For more info on collations, encodings, etc, please visit: Collations Info

Databases are heavily optimized for common usage scenarios (and LIKE is one of those).

You won't find a faster way of doing your search if you want to stay on the DB-level.

So basically I have been searching the solution for two days. I tried everything

• Installing Cmake
• Adding path
• installing dlib from the links mentioned in the answers
• Installing ## Heading ## numpy, scipy, matplotlib, pandas
• etc etc etc

BUT THE ONLY SOLUTION THAT WORKED WAS INSTALLING MICROSOFT VISUAL STUDIO C++

After installing MS VS C++ I ran command pip install dlib and it is working like a charm. BEST OF LUCK

Link to download Visual Studio C++

https://visualstudio.microsoft.com/thank-you-for-downloading-visual-studio-for-cplusplus/?sku=Community&rel=16&rid=30005

You can do a precheck with regular expression wheather they are numbers as like

function myFunction() {
    var y = document.getElementById("txt1").value;
    var z = document.getElementById("txt2").value;
    if((x.search(/[^0-9]/g) != -1)&&(y.search(/[^0-9]/g) != -1))
      var x = Number(y)+ Number(z);
    else
      alert("invalid values....");
    document.getElementById("demo").innerHTML = x;
  }

Try this.

public function insert_data_function($your_data)
{
    $this->db->insert("your_table",$your_data);
    $last_id = $this->db->insert_id();
    return $last_id;
}

Assuming that we're talking about overloading operator << for all classes derived from std::ostream to handle the Matrix class (and not overloading << for Matrix class), it makes more sense to declare the overload function outside the Math namespace in the header.

Use a friend function only if the functionality cannot be achieved via the public interfaces.

Matrix.h

namespace Math { 
    class Matrix { 
        //...
    };  
}
std::ostream& operator<<(std::ostream&, const Math::Matrix&);

Note that the operator overload is declared outside the namespace.

Matrix.cpp

using namespace Math;
using namespace std;

ostream& operator<< (ostream& os, const Matrix& obj) {
    os << obj.getXYZ() << obj.getABC() << '\n';
    return os;
}

On the other hand, if your overload function does need to be made a friend i.e. needs access to private and protected members.

Math.h

namespace Math {
    class Matrix {
        public:
            friend std::ostream& operator<<(std::ostream&, const Matrix&);
    };
}

You need to enclose the function definition with a namespace block instead of just using namespace Math;.

Matrix.cpp

using namespace Math;
using namespace std;

namespace Math {
    ostream& operator<<(ostream& os, const Matrix& obj) {
        os << obj.XYZ << obj.ABC << '\n';
        return os;
    }                 
}

I would suggest you override the addClass function. You can do it this way:

// Create a closure
(function(){
    // Your base, I'm in it!
    var originalAddClassMethod = jQuery.fn.addClass;

    jQuery.fn.addClass = function(){
        // Execute the original method.
        var result = originalAddClassMethod.apply( this, arguments );

        // call your function
        // this gets called everytime you use the addClass method
        myfunction();

        // return the original result
        return result;
    }
})();

// document ready function
$(function(){
    // do stuff
});

For simple things, I just use the XmlDocument/XmlNode/XmlAttribute classes and XmlDocument DOM found in System.XML.

It generates the XML for me, I just need to link a few items together.

However, on larger things, I use XML serialization.

The controller function/object represents an abstraction model-view-controller (MVC). While there is nothing new to write about MVC, it is still the most significant advanatage of angular: split the concerns into smaller pieces. And that's it, nothing more, so if you need to react on Model changes coming from View the Controller is the right person to do that job.

The story about link function is different, it is coming from different perspective then MVC. And is really essential, once we want to cross the boundaries of a controller/model/view (template).

Let' start with the parameters which are passed into the link function:

function link(scope, element, attrs) {

• scope is an Angular scope object.
• element is the jqLite-wrapped element that this directive matches.
• attrs is an object with the normalized attribute names and their corresponding values.

To put the link into the context, we should mention that all directives are going through this initialization process steps: Compile, Link. An Extract from Brad Green and Shyam Seshadri book Angular JS:

Compile phase (a sister of link, let's mention it here to get a clear picture):

In this phase, Angular walks the DOM to identify all the registered directives in the template. For each directive, it then transforms the DOM based on the directive’s rules (template, replace, transclude, and so on), and calls the compile function if it exists. The result is a compiled template function,

Link phase:

To make the view dynamic, Angular then runs a link function for each directive. The link functions typically creates listeners on the DOM or the model. These listeners keep the view and the model in sync at all times.

A nice example how to use the link could be found here: Creating Custom Directives. See the example: Creating a Directive that Manipulates the DOM, which inserts a "date-time" into page, refreshed every second.

Just a very short snippet from that rich source above, showing the real manipulation with DOM. There is hooked function to $timeout service, and also it is cleared in its destructor call to avoid memory leaks

.directive('myCurrentTime', function($timeout, dateFilter) {

 function link(scope, element, attrs) {

 ...

 // the not MVC job must be done
 function updateTime() {
   element.text(dateFilter(new Date(), format)); // here we are manipulating the DOM

Sorry but vim don't work that way.

You should switch to "normal" mode, navigate and then go back to insert again.

i == 'InvKey' && i == 'PostDate' will never be true, since i can never equal two different things at once.

You're probably trying to write

if (i !== 'InvKey' && i !== 'PostDate')) 

Unless you have more style sheets than that, you've messed up your break points:

#1 (max-width: 700px)
#2 (min-width: 701px) and (max-width: 900px)
#3 (max-width: 901px)

The 3rd media query is probably meant to be min-width: 901px. Right now, it overlaps #1 and #2, and only controls the page layout by itself when the screen is exactly 901px wide.

Edit for updated question:

(max-width: 640px)
(max-width: 800px)
(max-width: 1024px)
(max-width: 1280px)

Media queries aren't like catch or if/else statements. If any of the conditions match, then it will apply all of the styles from each media query it matched. If you only specify a min-width for all of your media queries, it's possible that some or all of the media queries are matched. In your case, a device that's 640px wide matches all 4 of your media queries, so all for style sheets are loaded. What you are most likely looking for is this:

(max-width: 640px)
(min-width: 641px) and (max-width: 800px)
(min-width: 801px) and (max-width: 1024px)
(min-width: 1025px)

Now there's no overlap. The styles will only apply if the device's width falls between the widths specified.

"DeprecationWarning: Unhandled promise rejections are deprecated"

TLDR: A promise has resolve and reject, doing a reject without a catch to handle it is deprecated, so you will have to at least have a catch at top level.

If multiple characters are bound inside a single integer/long, as was my issue:

s = '0123456789'
nchars = len(s)
# string to int or long. Type depends on nchars
x = sum(ord(s[byte])<<8*(nchars-byte-1) for byte in range(nchars))
# int or long to string
''.join(chr((x>>8*(nchars-byte-1))&0xFF) for byte in range(nchars))

Yields '0123456789' and x = 227581098929683594426425L

left = 37,up = 38, right = 39,down = 40

$(document).keydown(function(e) {
switch(e.which) {
    case 37:
    $( "#prev" ).click();
    break;

    case 38:
    $( "#prev" ).click();
    break;

    case 39:
    $( "#next" ).click();
    break;

    case 40:
    $( "#next" ).click();
    break;

    default: return;
}
e.preventDefault();

});

When you execute a method (i.e. function assigned to an object), inside it you can use this variable to refer to this object, for example:

var obj = {_x000D_
  someProperty: true,_x000D_
  someMethod: function() {_x000D_
    console.log(this.someProperty);_x000D_
  }_x000D_
};_x000D_
obj.someMethod(); // logs true

If you assign a method from one object to another, its this variable refers to the new object, for example:

var obj = {_x000D_
  someProperty: true,_x000D_
  someMethod: function() {_x000D_
    console.log(this.someProperty);_x000D_
  }_x000D_
};_x000D_
_x000D_
var anotherObj = {_x000D_
  someProperty: false,_x000D_
  someMethod: obj.someMethod_x000D_
};_x000D_
_x000D_
anotherObj.someMethod(); // logs false

The same thing happens when you assign requestAnimationFrame method of window to another object. Native functions, such as this, has build-in protection from executing it in other context.

There is a Function.prototype.call() function, which allows you to call a function in another context. You just have to pass it (the object which will be used as context) as a first parameter to this method. For example alert.call({}) gives TypeError: Illegal invocation. However, alert.call(window) works fine, because now alert is executed in its original scope.

If you use .call() with your object like that:

support.animationFrame.call(window, function() {});

it works fine, because requestAnimationFrame is executed in scope of window instead of your object.

However, using .call() every time you want to call this method, isn't very elegant solution. Instead, you can use Function.prototype.bind(). It has similar effect to .call(), but instead of calling the function, it creates a new function which will always be called in specified context. For example:

window.someProperty = true;_x000D_
var obj = {_x000D_
  someProperty: false,_x000D_
  someMethod: function() {_x000D_
    console.log(this.someProperty);_x000D_
  }_x000D_
};_x000D_
_x000D_
var someMethodInWindowContext = obj.someMethod.bind(window);_x000D_
someMethodInWindowContext(); // logs true

The only downside of Function.prototype.bind() is that it's a part of ECMAScript 5, which is not supported in IE <= 8. Fortunately, there is a polyfill on MDN.

As you probably already figured out, you can use .bind() to always execute requestAnimationFrame in context of window. Your code could look like this:

var support = {
    animationFrame: (window.requestAnimationFrame ||
        window.mozRequestAnimationFrame ||
        window.webkitRequestAnimationFrame ||
        window.msRequestAnimationFrame ||
        window.oRequestAnimationFrame).bind(window)
};

Then you can simply use support.animationFrame(function() {});.

Yes, this is probably a bit late. But one thing to add to everyone else's comments is that, Camel is actually a toolbox rather than a complete set of features. You should bear this in mind when developing and need to do various transformations and protocol conversions.

Camel itself relies on other frameworks and therefore sometimes you need to understand those as well in order to understand which is best suited for your needs. There are for example multiple ways to handle REST. This can get a bit confusing at first, but once you starting using and testing you will feel at ease and your knowledge of the different concepts will increase.

Even if I'm a bit late, I thought it would be interesting for future users to share some one-liners implementations I did using ES6.

One thing that I consider important depending on your environment or/and what you will do with with the data is to preserve the full byte value. For example, (5).toString(2) will give you 101, but the complete binary conversion is in reality 00000101, and that's why you might need to create a leftPad implementation to fill the string byte with leading zeros. But you may not need it at all, like other answers demonstrated.

If you run the below code snippet, you'll see the first output being the conversion of the abc string to a byte array and right after that the re-transformation of said array to it's corresponding string.

// For each byte in our array, retrieve the char code value of the binary value_x000D_
const binArrayToString = array => array.map(byte => String.fromCharCode(parseInt(byte, 2))).join('')_x000D_
_x000D_
// Basic left pad implementation to ensure string is on 8 bits_x000D_
const leftPad = str => str.length < 8 ? (Array(8).join('0') + str).slice(-8) : str_x000D_
_x000D_
// For each char of the string, get the int code and convert it to binary. Ensure 8 bits._x000D_
const stringToBinArray = str => str.split('').map(c => leftPad(c.charCodeAt().toString(2)))_x000D_
_x000D_
const array = stringToBinArray('abc')_x000D_
_x000D_
console.log(array)_x000D_
console.log(binArrayToString(array))

I recently found out that :active:focus does the same thing in css as :active:hover if you need to override a custom css library, they might use both.

Try the following code:

It's working without StoryBoard:

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: NSDictionary?) -> Bool {
    self.window = UIWindow(frame: UIScreen.mainScreen().bounds)
    self.window!.backgroundColor = UIColor.whiteColor()

    // Create a nav/vc pair using the custom ViewController class

    let nav = UINavigationController()
    let vc = ViewController(nibName: "ViewController", bundle: nil)

    // Push the vc onto the nav
    nav.pushViewController(vc, animated: false)

    // Set the window’s root view controller
    self.window!.rootViewController = nav

    // Present the window
    self.window!.makeKeyAndVisible()
    return true
}

It's not that hard...

I have just discovered an alternative way of opening a new tab with the Router.

On your template,

<a (click)="openNewTab()" >page link</a>

And on your component.ts, you can use serializeUrl to convert the route into a string, which can be used with window.open()

openNewTab() {
  const url = this.router.serializeUrl(
    this.router.createUrlTree(['/example'])
  );

  window.open(url, '_blank');
}

Neither <iostream> nor <iostream.h> are standard C header files. Your code is meant to be C++, where <iostream> is a valid header. Use g++ (and a .cpp file extension) for C++ code.

Alternatively, this program uses mostly constructs that are available in C anyway. It's easy enough to convert the entire program to compile using a C compiler. Simply remove #include <iostream> and using namespace std;, and replace cout << endl; with putchar('\n');... I advise compiling using C99 (eg. gcc -std=c99)

If you aren't comfortable with using negative margins, check this out.

div {
  position: fixed;
  left: 50%;
  bottom: 20px;
  transform: translate(-50%, -50%);
  margin: 0 auto;
}

<div>
  Your Text
</div>

Especially useful when you don't know the width of the div.

align="center" has no effect.

Since you have position:absolute, I would recommend positioning it 50% from the left and then subtracting half of its width from its left margin.

#manipulate {
    position:absolute;
    width:300px;
    height:300px;
    background:#063;
    bottom:0px;
    right:25%;
    left:50%;
    margin-left:-150px;
}

I think my answer will be more technical, but not different as the others present the same thing using different techniques.
So, first things first, the solution to this problem is the use of a design pattern known as "observer", it let's you decouple your data from your presentation, making the change in one thing be broadcasted to their listeners, but in this case it's made two-way.

For the DOM to JS way

To bind the data from the DOM to the js object you may add markup in the form of data attributes (or classes if you need compatibility), like this:

<input type="text" data-object="a" data-property="b" id="b" class="bind" value=""/>
<input type="text" data-object="a" data-property="c" id="c" class="bind" value=""/>
<input type="text" data-object="d" data-property="e" id="e" class="bind" value=""/>

This way it can be accessed via js using querySelectorAll (or the old friend getElementsByClassName for compatibility).

Now you can bind the event listening to the changes in to ways: one listener per object or one big listener to the container/document. Binding to the document/container will trigger the event for every change made in it or it's child, it willhave a smaller memory footprint but will spawn event calls.
The code will look something like this:

//Bind to each element
var elements = document.querySelectorAll('input[data-property]');

function toJS(){
    //Assuming `a` is in scope of the document
    var obj = document[this.data.object];
    obj[this.data.property] = this.value;
}

elements.forEach(function(el){
    el.addEventListener('change', toJS, false);
}

//Bind to document
function toJS2(){
    if (this.data && this.data.object) {
        //Again, assuming `a` is in document's scope
        var obj = document[this.data.object];
        obj[this.data.property] = this.value;
    }
}

document.addEventListener('change', toJS2, false);

For the JS do DOM way

You will need two things: one meta-object that will hold the references of witch DOM element is binded to each js object/attribute and a way to listen to changes in objects. It is basically the same way: you have to have a way to listen to changes in the object and then bind it to the DOM node, as your object "can't have" metadata you will need another object that holds metadata in a way that the property name maps to the metadata object's properties. The code will be something like this:

var a = {
        b: 'foo',
        c: 'bar'
    },
    d = {
        e: 'baz'
    },
    metadata = {
        b: 'b',
        c: 'c',
        e: 'e'
    };
function toDOM(changes){
    //changes is an array of objects changed and what happened
    //for now i'd recommend a polyfill as this syntax is still a proposal
    changes.forEach(function(change){
        var element = document.getElementById(metadata[change.name]);
        element.value = change.object[change.name];
    });
}
//Side note: you can also use currying to fix the second argument of the function (the toDOM method)
Object.observe(a, toDOM);
Object.observe(d, toDOM);

I hope that i was of help.

WARNING: There is a significant performance penalty with the live version of hover. It's especially noticeable in a large page on IE8.

I am working on a project where we load multi-level menus with AJAX (we have our reasons :). Anyway, I used the live method for the hover which worked great on Chrome (IE9 did OK, but not great). However, in IE8 It not only slowed down the menus (you had to hover for a couple seconds before it would drop), but everything on the page was painfully slow, including scrolling and even checking simple checkboxes.

Binding the events directly after they loaded resulted in adequate performance.

By using docker-compose:

Assuming that you have following directory layout:

$MYAPP_ROOT/docker-compose.yml

Introduction to Algorithms by Cormen et. al. is a standard introductory algorithms book, and is used by many universities, including my own. It has pretty good coverage and is very approachable.

And anything by Robert Sedgewick is good too.

SI = Source Index
DI = Destination Index

As others have indicated, they have special uses with the string instructions. For real mode programming, the ES segment register must be used with DI and DS with SI as in

movsb  es:di, ds:si

SI and DI can also be used as general purpose index registers. For example, the C source code

srcp [srcidx++] = argv [j];

compiles into

8B550C         mov    edx,[ebp+0C]
8B0C9A         mov    ecx,[edx+4*ebx]
894CBDAC       mov    [ebp+4*edi-54],ecx
47             inc    edi

where ebp+12 contains argv, ebx is j, and edi has srcidx. Notice the third instruction uses edi mulitplied by 4 and adds ebp offset by 0x54 (the location of srcp); brackets around the address indicate indirection.

AX = accumulator
DX = double word accumulator
CX = counter
BX = base register

They look like general purpose registers, but there are a number of instructions which (unexpectedly?) use one of them—but which one?—implicitly.

I use this:

import os,sys
from PIL import Image
from PIL.ExifTags import TAGS

for (k,v) in Image.open(sys.argv[1])._getexif().items():
        print('%s = %s' % (TAGS.get(k), v))

or to get a specific field:

def get_field (exif,field) :
  for (k,v) in exif.items():
     if TAGS.get(k) == field:
        return v

exif = image._getexif()
print get_field(exif,'ExposureTime')

You can do this:

fso.CopyFile "C:\Minecraft\options.txt", "H:\Minecraft\.minecraft\options.txt"

Include the filename in the folder that you copy to.

Regarding the benchmark suite mentioned, these results also hold for sorted arrays.

sort_by/reverse it is:

# foo.rb
require 'benchmark'

NUM_RUNS = 1000

# arr = []
arr1 = 3000.times.map { { num: rand(1000) } }
arr2 = 3000.times.map { |n| { num: n } }.reverse

Benchmark.bm(20) do |x|
  { 'randomized'     => arr1,
    'sorted'         => arr2 }.each do |label, arr|
    puts '---------------------------------------------------'
    puts label

    x.report('sort_by / reverse') {
      NUM_RUNS.times { arr.sort_by { |h| h[:num] }.reverse }
    }
    x.report('sort_by -') {
      NUM_RUNS.times { arr.sort_by { |h| -h[:num] } }
    }
  end
end

And the results:

$: ruby foo.rb
                           user     system      total        real
---------------------------------------------------

<Prefix> & for killing a window

<Prefix> x for killing a pane

If there is only one pane (i.e. the window is not split into multiple panes, <Prefix> x would kill the window)

As always iterated, <Prefix> is generally CTRL+b. (I think for beginner questions, we can just say CTRL+b all the time, and not talk about prefix at all, but anyway :) )

Module importing is quite fast, but not instant. This means that:

• Putting the imports at the top of the module is fine, because it's a trivial cost that's only paid once.
• Putting the imports within a function will cause calls to that function to take longer.

So if you care about efficiency, put the imports at the top. Only move them into a function if your profiling shows that would help (you did profile to see where best to improve performance, right??)

The best reasons I've seen to perform lazy imports are:

• Optional library support. If your code has multiple paths that use different libraries, don't break if an optional library is not installed.
• In the __init__.py of a plugin, which might be imported but not actually used. Examples are Bazaar plugins, which use bzrlib's lazy-loading framework.

Two ways to do this:

1) Using a Frame Layout

android:layout_gravity="bottom|right"

2) Using a Relative Layout

android:layout_alignParentRight="true"
android:layout_alignParentBottom="true" 

Instead of manually adding the package name on the build.gradle, you can do it this way:

first add this line at the beggining

import java.util.regex.Pattern

Then add this on the defaultConfig

android {
    ...
    defaultConfig {
        ...
        applicationId = doExtractStringFromManifest("package")
        ...
    }
    ...
}

And finally add the doExtractStringFromManifest method

def doExtractStringFromManifest(name) {
     def manifestFile = file(android.sourceSets.main.manifest.srcFile)
     def pattern = Pattern.compile(name + "=\"(\\S+)\"")
     def matcher = pattern.matcher(manifestFile.getText())
     matcher.find()
     return matcher.group(1)
}

As there are a lot of Cordova comments on the answer, if you are working with Cordova, you shouldn't really edit the build.gradle yourself, it has a comment at the beggining that say

// GENERATED FILE! DO NOT EDIT!

So, if you are using a Cordova, the best thing you can do is to update to cordova-android 5.1.0 or greater where this changes are already present.

I'd like to point out a use case for this that is not an anti-pattern, and there is no better way to do it.

This seems to be a missing feature in python.

There are a number of functions, like patch.object, that take the name of a method or property to be patched or accessed.

Consider this:

patch.object(obj, "method_name", new_reg)

This can potentially start "false succeeding" when you change the name of a method. IE: you can ship a bug, you thought you were testing.... simply because of a bad method name refactor.

Now consider: varname. This could be an efficient, built-in function. But for now it can work by iterating an object or the caller's frame:

Now your call can be:

patch.member(obj, obj.method_name, new_reg)

And the patch function can call:

varname(var, obj=obj)

This would: assert that the var is bound to the obj and return the name of the member. Or if the obj is not specified, use the callers stack frame to derive it, etc.

Could be made an efficient built in at some point, but here's a definition that works. I deliberately didn't support builtins, easy to add tho:

Feel free to stick this in a package called varname.py, and use it in your patch.object calls:

patch.object(obj, varname(obj, obj.method_name), new_reg)

Note: this was written for python 3.

String name = in.readLine(); ;
System.out.println("Hello " + name);

Without a block you can only declare variables and more than that assign them a value in single statement.

For method main() will be best choice for now:

public class details {
    public static void main(String[] args){
        BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
        System.out.println("What is your name?");
        String name = in.readLine(); ;
        System.out.println("Hello " + name);
    }
}

or If you want to use static block then...

public class details {
    static {
        BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
        System.out.println("What is your name?");
        String name = in.readLine(); ;
        System.out.println("Hello " + name);
    }
}

or if you want to build another method then..

public class details {
    public static void main(String[] args){
        myMethod();
    }
    private static void myMethod(){
        BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
        System.out.println("What is your name?");
        String name = in.readLine(); ;
        System.out.println("Hello " + name);
    }
}

Also worry about exception due to BufferedReader .

Linked to, but not explicitly mentioned here, is exactly when __all__ is used. It is a list of strings defining what symbols in a module will be exported when from <module> import * is used on the module.

For example, the following code in a foo.py explicitly exports the symbols bar and baz:

__all__ = ['bar', 'baz']

waz = 5
bar = 10
def baz(): return 'baz'

These symbols can then be imported like so:

from foo import *

print(bar)
print(baz)

# The following will trigger an exception, as "waz" is not exported by the module
print(waz)

If the __all__ above is commented out, this code will then execute to completion, as the default behaviour of import * is to import all symbols that do not begin with an underscore, from the given namespace.

Reference: https://docs.python.org/tutorial/modules.html#importing-from-a-package

NOTE: __all__ affects the from <module> import * behavior only. Members that are not mentioned in __all__ are still accessible from outside the module and can be imported with from <module> import <member>.

INSERT INTO TABLE_NAME (TIMESTAMP_VALUE) VALUES (TO_TIMESTAMP('2014-07-02 06:14:00.742000000', 'YYYY-MM-DD HH24:MI:SS.FF'));

In latest Angular 7/8, you can use the simplest approach:-

import { HttpClient, HttpHeaders, HttpParams } from '@angular/common/http';

getDetails(searchParams) {
    const httpOptions = {
        headers: { 'Content-Type': 'application/json' },
        params: { ...searchParams}
    };
    return this.http.get(this.Url, httpOptions);
}

WordPress overrides PHP's memory limit to 256M, with the assumption that whatever it was set to before is going to be too low to render the dashboard. You can override this by defining WP_MAX_MEMORY_LIMIT in wp-config.php:

define( 'WP_MAX_MEMORY_LIMIT' , '512M' );

I agree with DanFromGermany, 256M is really a lot of memory for rendering a dashboard page. Changing the memory limit is really putting a bandage on the problem.

Summarising @Rasmi Ranjan Nayak and @nogard answers and adding another option:

On the console

You should use the flag --gtest_filter, like

--gtest_filter=Test_Cases1*

(You can also do this in Properties|Configuration Properties|Debugging|Command Arguments)

On the environment

You should set the variable GTEST_FILTER like

export GTEST_FILTER = "Test_Cases1*"

On the code

You should set a flag filter, like

::testing::GTEST_FLAG(filter) = "Test_Cases1*";

such that your main function becomes something like

int main(int argc, char **argv) {
    ::testing::InitGoogleTest(&argc, argv);
    ::testing::GTEST_FLAG(filter) = "Test_Cases1*";
    return RUN_ALL_TESTS();
}

See section Running a Subset of the Tests for more info on the syntax of the string you can use.

GUID is Microsoft's implementation of the UUID standard.

Per Wikipedia:

The term GUID usually refers to Microsoft's implementation of the Universally Unique Identifier (UUID) standard.

An updated quote from that same Wikipedia article:

RFC 4122 itself states that UUIDs "are also known as GUIDs". All this suggests that "GUID", while originally referring to a variant of UUID used by Microsoft, has become simply an alternative name for UUID…

And it's unlikely too -- EOT is a fairly restrictive format that is supported only by IE. Both Safari 3.1 and Firefox 3.1 (well the current alpha) and possibly Opera 9.6 support true type font (ttf) embedding, and at least Safari supports SVG fonts through the same mechanism. A list apart had a good discussion about this a while back.

Subprocess is based on popen2, and as such has a number of advantages - there's a full list in the PEP here, but some are:

• using pipe in the shell
• better newline support
• better handling of exceptions

In your second example the "map" reference is of type Map, which is an interface implemented by HashMap (and other types of Map). This interface is a contract saying that the object maps keys to values and supports various operations (e.g. put, get). It says nothing about the implementation of the Map (in this case a HashMap).

The second approach is generally preferred as you typically wouldn't want to expose the specific map implementation to methods using the Map or via an API definition.

tooltips: {
            enabled: true,
                  mode: 'single',
                  callbacks: {
                    label: function(tooltipItems, data) { 
                      return data.datasets[tooltipItems.datasetIndex].label+": "+tooltipItems.yLabel;
                    }
                  }
                }

If you grep the command that you are looking for with a pipe from ps aux, it will wrap the text automatically. I used a lot of the other answers on here, but sometimes if you are looking for something specific, it is nice to just use grep and you know that it will wrap lines.

For instance ps aux | grep ffmpeg .

Applying the input-block-level class works great for me, across various screen widths. It is defined by Bootstrap in mixins.less as follows:

// Block level inputs
.input-block-level {
  display: block;
  width: 100%;
  min-height: 28px;        // Make inputs at least the height of their button counterpart
  .box-sizing(border-box); // Makes inputs behave like true block-level elements
}

This is very similar to the style suggested by 'assembler' in his comment on issue #1058.

Another important difference in this context would with process.stdout.clearLine() and process.stdout.cursorTo(0).

This would be useful if you want to show percentage of download or processing in the only one line. If you use clearLine(), cursorTo() with console.log() it doesn't work because it also append \n to the text. Just try out this example:

var waitInterval = 500;
var totalTime = 5000;
var currentInterval = 0;

function showPercentage(percentage){
    process.stdout.clearLine();
    process.stdout.cursorTo(0);
    console.log(`Processing ${percentage}%...` ); //replace this line with process.stdout.write(`Processing ${percentage}%...`);
}

var interval = setInterval(function(){
 currentInterval += waitInterval;
 showPercentage((currentInterval/totalTime) * 100);
}, waitInterval);

setTimeout(function(){
 clearInterval(interval); 
}, totalTime);

Emil's answer is correct, but it's my understanding that inet_ntoa is deprecated and that instead you should use inet_ntop. If you are using IPv4, cast your struct sockaddr to sockaddr_in. Your code will look something like this:

struct addrinfo *res;   // populated elsewhere in your code
struct sockaddr_in *ipv4 = (struct sockaddr_in *)res->ai_addr;
char ipAddress[INET_ADDRSTRLEN];
inet_ntop(AF_INET, &(ipv4->sin_addr), ipAddress, INET_ADDRSTRLEN);

printf("The IP address is: %s\n", ipAddress);

Take a look at this great resource for more explanation, including how to do this for IPv6 addresses.

You seem to be using grep() like the Unix grep utility, which is wrong.

Perl's grep() in scalar context evaluates the expression for each element of a list and returns the number of times the expression was true. So when $match contains any "true" value, grep($match, @array) in scalar context will always return the number of elements in @array.

Instead, try using the pattern matching operator:

if (grep /$match/, @array) {
    print "found it\n";
}

It sounds to me as if you actually mean "linux guests" and not "linux hosts".

But in any case, I suspect you did not install the VMWare Tools: doubleclick on that icon on the Desktop that can be seen on your screenshot. It will install some drivers that communicate with VMWare that, among other things, allow to adjust the screen resolution dynamically.

When the installation process is finished, you'll most likely have to reboot the VM.

The problem is that this character is UTF8, but json_encode does not handle it correctly. To say more, there is a list of other characters (see Unicode characters list), that will trigger the same error, so stripping off this one (Å) will not correct an issue to the end.

What we have used is to convert these chars to html entities like this:

htmlentities( (string) $value, ENT_QUOTES, 'utf-8', FALSE);

If you're using AFNetworking you can use its own implementation for internet reachability status.

The best way to use AFNetworking is to subclass the AFHTTPClient class and use this class to do your network connections.

One of the advantages of using this approach is that you can use blocks to set the desired behavior when the reachability status changes. Supposing that I've created a singleton subclass of AFHTTPClient (as said on the "Subclassing notes" on AFNetworking docs) named BKHTTPClient, I'd do something like:

BKHTTPClient *httpClient = [BKHTTPClient sharedClient];
[httpClient setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status)
{
    if (status == AFNetworkReachabilityStatusNotReachable) 
    {
    // Not reachable
    }
    else
    {
        // Reachable
    }
}];

You could also check for Wi-Fi or WLAN connections specifically using the AFNetworkReachabilityStatusReachableViaWWAN and AFNetworkReachabilityStatusReachableViaWiFi enums (more here).

It's good practice to use a context manager or call close() in case of exceptions during the file saving process. Could happen if your storage backend is down, etc.

Any overwrite behavior should be configured in your storage backend. For example S3Boto3Storage has a setting AWS_S3_FILE_OVERWRITE. If you're using FileSystemStorage you can write a custom mixin.

You might also want to call the model's save method instead of the FileField's save method if you want any custom side-effects to happen, like last-updated timestamps. If that's the case, you can also set the name attribute of the file to the name of the file - which is relative to MEDIA_ROOT. It defaults to the full path of the file which can cause problems if you don't set it - see File.__init__() and File.name.

Here's an example where self is the model instance where my_file is the FileField / ImageFile, calling save() on the whole model instance instead of just FileField:

import os
from django.core.files import File

with open(filepath, 'rb') as fi:
    self.my_file = File(fi, name=os.path.basename(fi.name))
    self.save()

If you want the server’s default error page to be displayed, you have to handle this in the server.

There is a modern API dedicated for this purpose - Broadcast Channel

It is as easy as:

var bc = new BroadcastChannel('test_channel');

bc.postMessage('This is a test message.'); /* send */

bc.onmessage = function (ev) { console.log(ev); } /* receive */

There is no need for the message to be just a DOMString, any kind of object can be sent.

Probably, apart from API cleanness, it is the main benefit of this API - no object stringification.

Currently supported only in Chrome and Firefox, but you can find a polyfill that uses localStorage.

After installation of Oracle Client 11.02.04, reboot the server and make sure USERS(Local Computer) is added with Full Control on Root folder for eg WWW

Tested, it worked.

maybe you need this.

>>> x = np.array([11,22])
>>> y = np.array([18,7,6])
>>> z = np.array([1,3,5])
>>> np.concatenate((x,y,z))
array([11, 22, 18,  7,  6,  1,  3,  5])

An HttpOnly cookie means that it's not available to scripting languages like JavaScript. So in JavaScript, there's absolutely no API available to get/set the HttpOnly attribute of the cookie, as that would otherwise defeat the meaning of HttpOnly.

Just set it as such on the server side using whatever server side language the server side is using. If JavaScript is absolutely necessary for this, you could consider to just let it send some (ajax) request with e.g. some specific request parameter which triggers the server side language to create an HttpOnly cookie. But, that would still make it easy for hackers to change the HttpOnly by just XSS and still have access to the cookie via JS and thus make the HttpOnly on your cookie completely useless.

My issue was due to target framework mentioned in windows service config was

<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6"/>
 </startup>

and my server in which I tried to install windows service was not supported for this .Net version.

Changing which , I could able to resolve the issue.

This is the correct syntax:

String arlist1 [] = { "value1`", "value2", "value3" };
JSONArray jsonArray1 = new JSONArray(arlist1);

For me, Visual Studio on Mac doesn't support Node.js (editing and debugging) whereas Visual Studio Code does this very well.

@: one-way binding

=: two-way binding

&: function binding

From MSDN Documentation

nvarchar [ ( n | max ) ]

Variable-length Unicode string data. n defines the string length and can be a value from 1 through 4,000. max indicates that the maximum storage size is 2^31-1 bytes (2 GB). The storage size, in bytes, is two times the actual length of data entered + 2 bytes

I got this error because I was using require('https') where I should have been using require('http').

Simply put: 1) make sure all items are comparable 2) sort the array 2) iterate over the array and find duplicates

Here is a working example that get IT skills that a job candidate does not already have.

//Get a list of skills from the Skill table
IEnumerable<Skill> skillenum = skillrepository.Skill;
//Get a list of skills the candidate has                   
IEnumerable<CandSkill> candskillenum = candskillrepository.CandSkill
       .Where(p => p.Candidate_ID == Candidate_ID);             
//Using the enum lists with LINQ filter out the skills not in the candidate skill list
IEnumerable<Skill> skillenumresult = skillenum.Where(p => !candskillenum.Any(p2 => p2.Skill_ID == p.Skill_ID));
//Assign the selectable list to a viewBag
ViewBag.SelSkills = new SelectList(skillenumresult, "Skill_ID", "Skill_Name", 1);

For me both these methods didn't work:

• navigationView.getMenu().getItem(0).setChecked(true);
• navigationView.setCheckedItem(id);

Try this one, it works for me.

onNavigationItemSelected(navigationView.getMenu().findItem(R.id.nav_profile));

1. First try npm install ,if the issue is not yet fixed try the following one after the other.
2. npm cache clean ,then
3. npm install -g npm,then npm install,Finally
4. ng serve --o to run the project. Hope this will help....

Get local file data in js(data.js) load:

function loadMyFile(){
    console.log("ut:"+unixTimeSec());
    loadScript("data.js?"+unixTimeSec(), loadParse);
}
function loadParse(){
    var mA_=mSdata.split("\n");
    console.log(mA_.length);
}
function loadScript(url, callback){

    var script = document.createElement("script")
    script.type = "text/javascript";

    if (script.readyState){  //IE
        script.onreadystatechange = function(){
            if (script.readyState == "loaded" ||
                    script.readyState == "complete"){
                script.onreadystatechange = null;
                callback();
            }
        };
    } else {  //Others
        script.onload = function(){
            callback();
        };

}
function unixTimeSec(){
    return Math.round( (new Date()).getTime()/1000);

For those looking for an example of how to pass the OAuth2 authorization (access token) in the header (as opposed to using a request or body parameter), here is how it's done:

Authorization: Bearer 0b79bab50daca910b000d4f1a2b675d604257e42

Using properties is to me more intuitive and fits better into most code.

Comparing

o.x = 5
ox = o.x

vs.

o.setX(5)
ox = o.getX()

is to me quite obvious which is easier to read. Also properties allows for private variables much easier.

As Darin says, you can read from the input stream - but I'd avoid relying on all the data being available in a single go. If you're using .NET 4 this is simple:

MemoryStream target = new MemoryStream();
model.File.InputStream.CopyTo(target);
byte[] data = target.ToArray();

It's easy enough to write the equivalent of CopyTo in .NET 3.5 if you want. The important part is that you read from HttpPostedFileBase.InputStream.

For efficient purposes you could check whether the stream returned is already a MemoryStream:

byte[] data;
using (Stream inputStream = model.File.InputStream)
{
    MemoryStream memoryStream = inputStream as MemoryStream;
    if (memoryStream == null)
    {
        memoryStream = new MemoryStream();
        inputStream.CopyTo(memoryStream);
    }
    data = memoryStream.ToArray();
}

In Pro Angular-6 book is detailed as below;

• valid: This property returns true if the element’s contents are valid and false otherwise.

• invalid: This property returns true if the element’s contents are invalid and false otherwise.

• pristine: This property returns true if the element’s contents have not been changed.

• dirty: This property returns true if the element’s contents have been changed.
• untouched: This property returns true if the user has not visited the element.
• touched: This property returns true if the user has visited the element.

There are two problems in your code:

• The property is called visibility and not visiblity.
• It is not a property of the element itself but of its .style property.

It's easy to fix. Simple replace this:

document.getElementById("remember").visiblity

with this:

document.getElementById("remember").style.visibility

First, make sure the listener on database server (computer A) that receives client connection requests is running. To do so, run lsnrctl status command.

In case, if you get TNS:no listener message (see below image), it means listener service is not running. To start it, run lsnrctl start command.

Second, for database operations and connectivity from remote clients, the following executables must be added to the Windows Firewall exception list: (see image)

Oracle_home\bin\oracle.exe - Oracle Database executable

Oracle_home\bin\tnslsnr.exe - Oracle Listener

Finally, install oracle instant client on client machine (computer B) and run:

sqlplus user/password@computerA:port/XE

Since Swift 4.2

There is a new set of APIs:

let randomIntFrom0To10 = Int.random(in: 0 ..< 10)
let randomDouble = Double.random(in: 1 ... 10)

• All numeric types now have the random(in:) method that takes range.

• It returns a number uniformly distributed in that range.

TL;DR

Well, what is wrong with the "good" old way?

1. You have to use imported C APIs (They are different between platforms).

2. And moreover...

What if I told you that the random is not that random?

If you use arc4random() (to calculate the remainder) like arc4random() % aNumber, the result is not uniformly distributed between the 0 and aNumber. There is a problem called the Modulo bias.

Modulo bias

Normally, the function generates a random number between 0 and MAX (depends on the type etc.). To make a quick, easy example, let's say the max number is 7 and you care about a random number in the range 0 ..< 2 (or the interval [0, 3) if you prefer that).

The probabilities for individual numbers are:

• 0: 3/8 = 37.5%
• 1: 3/8 = 37.5%
• 2: 2/8 = 25%

In other words, you are more likely to end up with 0 or 1 than 2. Of course, bare in mind that this is extremely simplified and the MAX number is much higher, making it more "fair".

This problem is addressed by SE-0202 - Random unification in Swift 4.2

Because the compiler knows the binding at compile time. If you invoke a method on an interface, for example, then the compiler can't know and the binding is resolved at runtime because the actual object having a method invoked on it could possible be one of several. Therefore that is runtime or dynamic binding.

Your invocation is bound to the Animal class at compile time because you've specified the type. If you passed that variable into another method somewhere else, noone would know (apart from you because you wrote it) what actual class it would be. The only clue is the declared type of Animal.

There is really quite a number of ways to do this and all of the above are in one way or another valid approaches... Let me add a straightforward proposition. So assuming your current existing json file looks is this....

{
     "name":"myname"
}

And you want to bring in this new json content (adding key "id")

{
     "id": "134",
     "name": "myname"
 }

My approach has always been to keep the code extremely readable with easily traceable logic. So first, we read the entire existing json file into memory, assuming you are very well aware of your json's existing key(s).

import json 

# first, get the absolute path to json file
PATH_TO_JSON = 'data.json' #  assuming same directory (but you can work your magic here with os.)

# read existing json to memory. you do this to preserve whatever existing data. 
with open(PATH_TO_JSON,'r') as jsonfile:
    json_content = json.load(jsonfile) # this is now in memory! you can use it outside 'open'

Next, we use the 'with open()' syntax again, with the 'w' option. 'w' is a write mode which lets us edit and write new information to the file. Here s the catch that works for us ::: any existing json with the same target write name will be erased automatically.

So what we can do now, is simply write to the same filename with the new data

# add the id key-value pair (rmbr that it already has the "name" key value)
json_content["id"] = "134"

with open(PATH_TO_JSON,'w') as jsonfile:
    json.dump(json_content, jsonfile, indent=4) # you decide the indentation level

And there you go! data.json should be good to go for an good old POST request

index(substring [, offset]) ? fixnum or nil
index(regexp [, offset]) ? fixnum or nil

Returns the index of the first occurrence of the given substring or pattern (regexp) in str. Returns nil if not found. If the second parameter is present, it specifies the position in the string to begin the search.

"hello".index('e')             #=> 1
"hello".index('lo')            #=> 3
"hello".index('a')             #=> nil
"hello".index(?e)              #=> 1
"hello".index(/[aeiou]/, -3)   #=> 4

Check out ruby documents for more information.

Another option is to use the Aggregate extension rather than Join:

String s = myDict.Select(x => x.Key + "=" + x.Value).Aggregate((s1, s2) => s1 + ";" + s2);

Had a similar problem. I updated my Genymotion and my android SDK's/libraries/dependencies and all seemed to work. To update my SDK's I used android sdk manager {ANDROID_SDK_FOLDER}/tools/android sdk

You don't need case in the where statement, just use parentheses and or:

Select * From Times
WHERE StartDate <= @Date AND EndDate >= @Date
AND (
    (@day = 'Monday' AND Monday = 1)
    OR (@day = 'Tuesday' AND Tuesday = 1)
    OR Wednesday = 1
)

Additionally, your syntax is wrong for a case. It doesn't append things to the string--it returns a single value. You'd want something like this, if you were actually going to use a case statement (which you shouldn't):

Select * From Times
WHERE (StartDate <= @Date) AND (EndDate >= @Date)
AND 1 = CASE WHEN @day = 'Monday' THEN Monday
             WHEN @day = 'Tuesday' THEN Tuesday
             ELSE Wednesday
        END 

And just for an extra umph, you can use the between operator for your date:

where @Date between StartDate and EndDate

Making your final query:

select
    * 
from 
    Times
where
    @Date between StartDate and EndDate
    and (
        (@day = 'Monday' and Monday = 1)
        or (@day = 'Tuesday' and Tuesday = 1)
        or Wednesday = 1
    )

An "if" is not a loop. Just use the break inside the "if" and it will break out of the "while".

If you ever need to use genuine nested loops, Java has the concept of a labeled break. You can put a label before a loop, and then use the name of the label is the argument to break. It will break outside of the labeled loop.

asp:TextBox ID="txtName" placeholder="any text here"

The solutions above work fine for local testing and firing up browsers from the java code.If you fancy firing up your selenium grid later then this parameter is a must have in order to tell the remote node where to find the geckodriver:

-Dwebdriver.gecko.driver="C:\geckodriver\geckodriver.exe"

The node cannot find the gecko driver when specified in the Automation Java code.

So the complete command for the node whould be (assuming node and hub for test purposes live on same machine) :

java -Dwebdriver.gecko.driver="C:\geckodriver\geckodriver.exe" -jar selenium-server-standalone-2.53.0.jar -role node -hub http://localhost:4444/grid/register

And you should expect to see in the node log :

00:35:44.383 INFO - Launching a Selenium Grid node
Setting system property webdriver.gecko.driver to C:\geckodriver\geckodriver.exe

You can use offsetWidth. Refer to this post and question for more.

console.log("width:" + document.getElementsByTagName("div")[0].offsetWidth + "px");

div {border: 1px solid #F00;}

<div style="width: 100%; height: 10px;"></div>

}

I find this explanation quite clear (it's pure copy from Technet):

There are two types of temporary tables: local and global. Local temporary tables are visible only to their creators during the same connection to an instance of SQL Server as when the tables were first created or referenced. Local temporary tables are deleted after the user disconnects from the instance of SQL Server. Global temporary tables are visible to any user and any connection after they are created, and are deleted when all users that are referencing the table disconnect from the instance of SQL Server.

You can try to develop some sort of a generic component that accepts a SynchronizationContext as input and uses it to invoke the events.

Models must be named and called with the first letter of the model name capitalized and the rest in lowercase.

For example: $this->load->model('Logon_model');

and:

class Logon_model extends CI_Model {
...

But you are correct about the file name.

Here is a lengthy article on stdin, stdout and stderr:

• What Are stdin, stdout, and stderr on Linux?

To summarize:

Streams Are Handled Like Files

Streams in Linux—like almost everything else—are treated as though they were files. You can read text from a file, and you can write text into a file. Both of these actions involve a stream of data. So the concept of handling a stream of data as a file isn’t that much of a stretch.

Each file associated with a process is allocated a unique number to identify it. This is known as the file descriptor. Whenever an action is required to be performed on a file, the file descriptor is used to identify the file.

These values are always used for stdin, stdout, and stderr:

0: stdin
1: stdout
2: stderr

Ironically I found this question on stack overflow and the article above because I was searching for information on abnormal / non-standard streams. So my search continues.

The example, I have used today:

import PIL
import numpy
from PIL import Image

def resize_image(numpy_array_image, new_height):
    # convert nympy array image to PIL.Image
    image = Image.fromarray(numpy.uint8(numpy_array_image))
    old_width = float(image.size[0])
    old_height = float(image.size[1])
    ratio = float( new_height / old_height)
    new_width = int(old_width * ratio)
    image = image.resize((new_width, new_height), PIL.Image.ANTIALIAS)
    # convert PIL.Image into nympy array back again
    return array(image)

String s = "prefix/dir1/dir2/dir3/dir4"

String parts[] = s.split("/");

System.out.println(s[0]); // "prefix"
System.out.println(s[1]); // "dir1"
...

This works for me:

<input id="AllowRating" type="checkbox" @(Model.AllowRating?"checked='checked'":"")    style="" onchange="" />

If you really wants to use HTML Helpers:

@Html.CheckBoxFor(m => m.AllowRating, new { @checked = Model.AllowRating})

New in python 3.8, you can pass a delimiter argument to the hex function, as in this example

>>> value = b'\xf0\xf1\xf2'
>>> value.hex('-')
'f0-f1-f2'
>>> value.hex('_', 2)
'f0_f1f2'
>>> b'UUDDLRLRAB'.hex(' ', -4)
'55554444 4c524c52 4142'

The previous answers are quite complete regarding what :: method reference does. To sum up, it provides a way to refer to a method(or constructor) without executing it, and when evaluated, it creates an instance of the functional interface that provides the target type context.

Below are two examples to find an object with the max value in an ArrayList WITH and WITHOUT the use of :: method reference. Explanations are in the comments below.

WITHOUT the use of ::

import java.util.*;

class MyClass {
    private int val;
    MyClass (int v) { val = v; }
    int getVal() { return val; }
}

class ByVal implements Comparator<MyClass> {
    // no need to create this class when using method reference
    public int compare(MyClass source, MyClass ref) {
        return source.getVal() - ref.getVal();
    }
}

public class FindMaxInCol {
    public static void main(String args[]) {
        ArrayList<MyClass> myClassList = new ArrayList<MyClass>();
        myClassList.add(new MyClass(1));
        myClassList.add(new MyClass(0));
        myClassList.add(new MyClass(3));
        myClassList.add(new MyClass(6));

        MyClass maxValObj = Collections.max(myClassList, new ByVal());
    }
}

WITH the use of ::

import java.util.*;

class MyClass {
    private int val;
    MyClass (int v) { val = v; }
    int getVal() { return val; }
}

public class FindMaxInCol {
    static int compareMyClass(MyClass source, MyClass ref) {
        // This static method is compatible with the compare() method defined by Comparator. 
        // So there's no need to explicitly implement and create an instance of Comparator like the first example.
        return source.getVal() - ref.getVal();
    }

    public static void main(String args[]) {
        ArrayList<MyClass> myClassList = new ArrayList<MyClass>();
        myClassList.add(new MyClass(1));
        myClassList.add(new MyClass(0));
        myClassList.add(new MyClass(3));
        myClassList.add(new MyClass(6));

        MyClass maxValObj = Collections.max(myClassList, FindMaxInCol::compareMyClass);
    }
}

almost there, just change outerWidth: 100%; to width: auto; (outerWidth is not a CSS property)

alternatively, apply the following styles to bar:

width: auto;
display: block;
