Redirect the output to DEVNULL:

import os
import subprocess

FNULL = open(os.devnull, 'w')
retcode = subprocess.call(['echo', 'foo'], 
    stdout=FNULL, 
    stderr=subprocess.STDOUT)

It is effectively the same as running this shell command:

retcode = os.system("echo 'foo' &> /dev/null")

Update: This answer applies to the original question relating to python 2.7. As of python >= 3.3 an official subprocess.DEVNULL symbol was added.

retcode = subprocess.call(['echo', 'foo'], 
    stdout=subprocess.DEVNULL, 
    stderr=subprocess.STDOUT)

To clarify some points:

As jro has mentioned, the right way is to use subprocess.communicate.

Yet, when feeding the stdin using subprocess.communicate with input, you need to initiate the subprocess with stdin=subprocess.PIPE according to the docs.

Note that if you want to send data to the process’s stdin, you need to create the Popen object with stdin=PIPE. Similarly, to get anything other than None in the result tuple, you need to give stdout=PIPE and/or stderr=PIPE too.

Also qed has mentioned in the comments that for Python 3.4 you need to encode the string, meaning you need to pass Bytes to the input rather than a string. This is not entirely true. According to the docs, if the streams were opened in text mode, the input should be a string (source is the same page).

If streams were opened in text mode, input must be a string. Otherwise, it must be bytes.

So, if the streams were not opened explicitly in text mode, then something like below should work:

import subprocess
command = ['myapp', '--arg1', 'value_for_arg1']
p = subprocess.Popen(command, stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
output = p.communicate(input='some data'.encode())[0]

I've left the stderr value above deliberately as STDOUT as an example.

That being said, sometimes you might want the output of another process rather than building it up from scratch. Let's say you want to run the equivalent of echo -n 'CATCH\nme' | grep -i catch | wc -m. This should normally return the number characters in 'CATCH' plus a newline character, which results in 6. The point of the echo here is to feed the CATCH\nme data to grep. So we can feed the data to grep with stdin in the Python subprocess chain as a variable, and then pass the stdout as a PIPE to the wc process' stdin (in the meantime, get rid of the extra newline character):

import subprocess

what_to_catch = 'catch'
what_to_feed = 'CATCH\nme'

# We create the first subprocess, note that we need stdin=PIPE and stdout=PIPE
p1 = subprocess.Popen(['grep', '-i', what_to_catch], stdin=subprocess.PIPE, stdout=subprocess.PIPE)

# We immediately run the first subprocess and get the result
# Note that we encode the data, otherwise we'd get a TypeError
p1_out = p1.communicate(input=what_to_feed.encode())[0]

# Well the result includes an '\n' at the end, 
# if we want to get rid of it in a VERY hacky way
p1_out = p1_out.decode().strip().encode()

# We create the second subprocess, note that we need stdin=PIPE
p2 = subprocess.Popen(['wc', '-m'], stdin=subprocess.PIPE, stdout=subprocess.PIPE)

# We run the second subprocess feeding it with the first subprocess' output.
# We decode the output to convert to a string
# We still have a '\n', so we strip that out
output = p2.communicate(input=p1_out)[0].decode().strip()

This is somewhat different than the response here, where you pipe two processes directly without adding data directly in Python.

Hope that helps someone out.

Very simple use of any

df <- <your structure>

df$Den <- apply(df,1,function(i) {ifelse(any(is.na(i)) | any(i != 1), 0, 1)})

It is neccesary to provide Group Id and Artifact Id to download the jar file you need. If you want to search it just use * , * for these fields.

Use a table variable or a temporary table.

As has been mentioned before, a cursor is a last resort. Mostly because it uses lots of resources, issues locks and might be a sign you're just not understanding how to use SQL properly.

Side note: I once came across a solution that used cursors to update rows in a table. After some scrutiny, it turned out the whole thing could be replaced with a single UPDATE command. However, in this case, where a stored procedure should be executed, a single SQL-command won't work.

Create a table variable like this (if you're working with lots of data or are short on memory, use a temporary table instead):

DECLARE @menus AS TABLE (
    id INT IDENTITY(1,1),
    parent NVARCHAR(128),
    child NVARCHAR(128));

The id is important.

Replace parent and child with some good data, e.g. relevant identifiers or the whole set of data to be operated on.

Insert data in the table, e.g.:

INSERT INTO @menus (parent, child) 
  VALUES ('Some name',  'Child name');
...
INSERT INTO @menus (parent,child) 
  VALUES ('Some other name', 'Some other child name');

Declare some variables:

DECLARE @id INT = 1;
DECLARE @parentName NVARCHAR(128);
DECLARE @childName NVARCHAR(128);

And finally, create a while loop over the data in the table:

WHILE @id IS NOT NULL
BEGIN
    SELECT @parentName = parent,
           @childName = child 
        FROM @menus WHERE id = @id;

    EXEC myProcedure @parent=@parentName, @child=@childName;

    SELECT @id = MIN(id) FROM @menus WHERE id > @id;
END

The first select fetches data from the temporary table. The second select updates the @id. MIN returns null if no rows were selected.

An alternative approach is to loop while the table has rows, SELECT TOP 1 and remove the selected row from the temp table:

WHILE EXISTS(SELECT 1 FROM @menuIDs) 
BEGIN
    SELECT TOP 1 @menuID = menuID FROM @menuIDs;

    EXEC myProcedure @menuID=@menuID;

    DELETE FROM @menuIDs WHERE menuID = @menuID;
END;

You can use the function MROUND(<reference cell>, <round to multiple of digit needed>).

Example:

1. For a value A1 = 21 round to multiple of 10 it would be written as =MROUND(A1,10) for which Result = 20

2. For a value Z4 = 55.1 round to multiple of 10 it would be written as =MROUND(Z4,10) for which Result = 60

In JUnit 4, another option for you may be to create an annotation to denote that the test needs to meet your custom criteria, then extend the default runner with your own and using reflection, base your decision on the custom criteria. It may look something like this:

public class CustomRunner extends BlockJUnit4ClassRunner {
    public CTRunner(Class<?> klass) throws initializationError {
        super(klass);
    }

    @Override
    protected boolean isIgnored(FrameworkMethod child) {
        if(shouldIgnore()) {
            return true;
        }
        return super.isIgnored(child);
    }

    private boolean shouldIgnore(class) {
        /* some custom criteria */
    }
}

Simply specify whether you want the time to be greater, smaller, or equal to the time you want, using, respectively:

find . -cmin +<time>
find . -cmin -<time>
find . -cmin  <time>

In your case, for example, the files with last edition in a maximum of 5 minutes, are given by:

find . -cmin -5

Gradle caches artifacts in USER_HOME/.gradle folder. The compiled scripts are usually in the .gradle folder in your project folder.

If you can't find the cache, maybe it's because you have not cached any artifacts yet. You can always see where Gradle has cached artifacts with a simple script:

apply plugin: 'java'

repositories{
  mavenCentral()
}

dependencies{
  compile 'com.google.guava:guava:12.0'
}

task showMeCache << {
  configurations.compile.each { println it }
}

Now if you run gradle showMeCache it should download the deps into cache and print the full path.

Let me clear two points here :

• firstly non-default argument should not follow default argument , it means you can't define (a=b,c) in function the order of defining parameter in function are :
  • positional parameter or non-default parameter i.e (a,b,c)
  • keyword parameter or default parameter i.e (a="b",r="j")
  • keyword-only parameter i.e (*args)
  • var-keyword parameter i.e (**kwargs)

def example(a, b, c=None, r="w" , d=[], *ae, **ab):

(a,b) are positional parameter

(c=none) is optional parameter

(r="w") is keyword parameter

(d=[]) is list parameter

(*ae) is keyword-only

(**ab) is var-keyword parameter

• now secondary thing is if i try something like this : def example(a, b, c=a,d=b):

argument is not defined when default values are saved,Python computes and saves default values when you define the function

c and d are not defined, does not exist, when this happens (it exists only when the function is executed)

"a,a=b" its not allowed in parameter.

var req = { mandrill_events: '[{"event":"inbound","ts":1426249238}]' }

console.log(Object.keys(req)[0]);

Make any Object array (req), then simply do Object.keys(req)[0] to pick the first key in the Object array.

A very easy solution worked for me:

  if (62 % 50 != 0) {
      var number = 62 / 50 + 1 // adding 1 is doing the actual "round up"
  }

number contains value 2

That's definitely possible. We'll take a general case with Apache here.

Let's say you're a big Symfony2 fan and you would like to access your symfony website at http://symfony.local/ from 4 different computers (the main one hosting your website, as well as a Mac, a Windows and a Linux distro connected (wireless or not) to the main computer.

General Sketch:

1 Set up a virtual host:

You first need to set up a virtual host in your apache httpd-vhosts.conf file. On XAMP, you can find this file here: C:\xampp\apache\conf\extra\httpd-vhosts.conf. On MAMP, you can find this file here: Applications/MAMP/conf/apache/extra/httpd-vhosts.conf. This step prepares the Web server on your computer for handling symfony.local requests. You need to provide the name of the Virtual Host as well as the root/main folder of your website. To do this, add the following line at the end of that file. You need to change the DocumentRoot to wherever your main folder is. Here I have taken /Applications/MAMP/htdocs/Symfony/ as the root of my website.

<VirtualHost *:80>
    DocumentRoot "/Applications/MAMP/htdocs/Symfony/"
    ServerName symfony.local
</VirtualHost>

2 Configure your hosts file:

For the client (your browser in that case) to understand what symfony.local really means, you need to edit the hosts file on your computer. Everytime you type an URL in your browser, your computer tries to understand what it means! symfony.local doesn't mean anything for a computer. So it will try to resolve the name symfony.local to an IP address. It will do this by first looking into the hosts file on your computer to see if he can match an IP address to what you typed in the address bar. If it can't, then it will ask DNS servers. The trick here is to append the following to your hosts file.

• On MAC, this file is in /private/etc/hosts;
• On LINUX, this file is in /etc/hosts;
• On WINDOWS, this file is in \Windows\system32\private\etc\hosts;
• On WINDOWS 7, this file is in \Windows\system32\drivers\etc\hosts;
• On WINDOWS 10, this file is in \Windows\system32\drivers\etc\hosts;

Hosts file

##
# Host Database
# localhost is used to configure the loopback interface
##
#...
127.0.0.1           symfony.local

From now on, everytime you type symfony.local on this computer, your computer will use the loopback interface to connect to symfony.local. It will understand that you want to work on localhost (127.0.0.1).

3 Access symfony.local from an other computer:

We finally arrive to your main question which is:

How can I now access my website through an other computer?

Well this is now easy! We just need to tell the other computers how they could find symfony.local! How do we do this?

3a Get the IP address of the computer hosting the website:

We first need to know the IP address on the computer that hosts the website (the one we've been working on since the very beginning). In the terminal, on MAC and LINUX type ifconfig |grep inet, on WINDOWS type ipconfig. Let's assume the IP address of this computer is 192.168.1.5.

3b Edit the hosts file on the computer you are trying to access the website from.:

Again, on MAC, this file is in /private/etc/hosts; on LINUX, in /etc/hosts; and on WINDOWS, in \Windows\system32\private\etc\hosts (if you're using WINDOWS 7, this file is in \Windows\system32\drivers\etc\hosts).. The trick is now to use the IP address of the computer we are trying to access/talk to:

##
# Host Database
# localhost is used to configure the loopback interface
##
#...
192.168.1.5         symfony.local

4 Finally enjoy the results in your browser

You can now go into your browser and type http://symfony.local to beautifully see your website on different computers! Note that you can apply the same strategy if you are a OSX user to test your website on Internet Explorer via Virtual Box (if you don't want to use a Windows computer). This is beautifully explained in Crafting Your Windows / IE Test Environment on OSX.

You can also access your localhost from mobile devices

You might wonder how to access your localhost website from a mobile device. In some cases, you won't be able to modify the hosts file (iPhone, iPad...) on your device (jailbreaking excluded).

Well, the solution then is to install a proxy server on the machine hosting the website and connect to that proxy from your iphone. It's actually very well explained in the following posts and is not that long to set up:

On a Mac, I would recommend: Testing a Mac OS X web site using a local hostname on a mobile device: Using SquidMan as a proxy. It's a 100% free solution. Some people can also use Charles as a proxy server but it's 50$.

On Linux, you can adapt the Mac OS way above by using Squid as a proxy server.

On Windows, you can do that using Fiddler. The solution is described in the following post: Monitoring iPhone traffic with Fiddler

Edit 23/11/2017: Hey I don't want to modify my Hosts file

@Dre. Any possible way to access the website from another computer by not editing the host file manually? let's say I have 100 computers wanted to access the website

This is an interesting question, and as it is related to the OP question, let me help.

You would have to do a change on your network so that every machine knows where your website is hosted. Most everyday routers don't do that so you would have to run your own DNS Server on your network.

Let's pretend you have a router (192.168.1.1). This router has a DHCP server and allocates IP addresses to 100 machines on the network.

Now, let's say you have, same as above, on the same network, a machine at 192.168.1.5 which has your website. We will call that machine pompei.

$ echo $HOSTNAME
pompei

Same as before, that machine pompei at 192.168.1.5 runs an HTTP Server which serves your website symfony.local.

For every machine to know that symfony.local is hosted on pompei we will now need a custom DNS Server on the network which knows where symfony.local is hosted. Devices on the network will then be able to resolve domain names served by pompei internally.

3 simple steps.

Step 1: DNS Server

Set-up a DNS Server on your network. Let's have it on pompei for convenience and use something like dnsmasq.

Dnsmasq provides Domain Name System (DNS) forwarder, ....

We want pompei to run DNSmasq to handle DNS requests Hey, pompei, where is symfony.local and respond Hey, sure think, it is on 192.168.1.5 but don't take my word for it.

Go ahead install dnsmasq, dnsmasq configuration file is typically in /etc/dnsmasq.conf depending on your environment.

I personally use no-resolv and google servers server=8.8.8.8 server=8.8.8.4.

*Note:* ALWAYS restart DNSmasq if modifying /etc/hosts file as no changes will take effect otherwise.

Step 2: Firewall

To work, pompei needs to allow incoming and outgoing 'domain' packets, which are going from and to port 53. Of course! These are DNS packets and if pompei does not allow them, there is no way for your DNS server to be reached at all. Go ahead and open that port 53. On linux, you would classically use iptables for this.

Sharing what I came up with but you will very likely have to dive into your firewall and understand everything well.

#
# Allow outbound DNS port 53
#
 iptables -A INPUT -p tcp --dport 53 -j ACCEPT
 iptables -A INPUT -p udp --dport 53 -j ACCEPT

 iptables -A OUTPUT -p tcp --dport 53 -j ACCEPT
 iptables -A OUTPUT -p udp --dport 53 -j ACCEPT

 iptables -A INPUT -p udp --sport 53 -j ACCEPT
 iptables -A INPUT -p tcp --sport 53 -j ACCEPT

 iptables -A OUTPUT -p tcp --sport 53 -j ACCEPT
 iptables -A OUTPUT -p udp --sport 53 -j ACCEPT

Step 3: Router

Tell your router that your dns server is on 192.168.1.5 now. Most of the time, you can just login into your router and change this manually very easily.

That's it, When you are on a machine and ask for symfony.local, it will ask your DNS Server where symfony.local is hosted, and as soon as it has received its answer from the DNS server, will then send the proper HTTP request to pompei on 192.168.1.5.

I let you play with this and enjoy the ride. These 2 steps are the main guidelines, so you will have to debug and spend a few hours if this is the first time you do it. Let's say this is a bit more advanced networking, there are primary DNS Server, secondary DNS Servers, etc.. Good luck!

$("#datepicker").datepicker("option", "dateFormat", "yy-mm-dd ");

For the time picker, you should add timepicker to Datepicker, and it would be formatted with one equivalent command.

EDIT

Use this one that extend jQuery UI Datepicker. You can pick up both date and time.

http://trentrichardson.com/examples/timepicker/

Use a Linux Live cd/usb and boot an that to be able to directly connect to your wifi hardware or use linux as the main OS with direct access to the wifi card and then use windows as a guest os, I know that this maybe not the ideal way but it will work.

If you want to do that why not go with a while, for ease of mind? :P No, but seriously I didn't know that and seems kinda nice so thanks, nice to know!

As mentioned by Seeker, the problem could have been that you setup the click() function too soon. From your code snippet, we cannot know where you placed the script and whether it gets run at the right time.

An important point is to run such scripts after the document is ready. This is done by placing the click() initialization within that other function as in:

jQuery(document).ready(function()
  {
    jQuery("body").click(function()
      {
        // ... your click code here ...
      });
  });

This is usually the best method, especially if you include your JavaScript code in your <head> tag. If you include it at the very bottom of the page, then the ready() function is less important, but it may still be useful.

Another way to get this error is by accidentally writing the definition of something in an anonymous namespace:

foo.h:

namespace foo {
    void bar();
}

foo.cc:

namespace foo {
    namespace {  // wrong
        void bar() { cout << "hello"; };
    }
}

other.cc file:

#include "foo.h"

void baz() {
    foo::bar();
}

Go to the bottom of the file

• G
• Shift + g

Go to the top of the file

• g+g

Its very simple. Just create a View with the black background color.

<View
    android:layout_width="match_parent"
    android:layout_height="1dp"
    android:background="#000"/>

This will create a horizontal line with background color. You can also add other attributes such as margins, paddings etc just like any other view.

Here is some good explaination. check out it.

CHECKPOINT; 
GO 
DBCC DROPCLEANBUFFERS; 
GO

From the linked article:

If all of the performance testing is conducted in SQL Server the best approach may be to issue a CHECKPOINT and then issue the DBCC DROPCLEANBUFFERS command. Although the CHECKPOINT process is an automatic internal system process in SQL Server and occurs on a regular basis, it is important to issue this command to write all of the dirty pages for the current database to disk and clean the buffers. Then the DBCC DROPCLEANBUFFERS command can be executed to remove all buffers from the buffer pool.

I encountered the same error message but don't have any access to the table like "dba_free_space" because I am not a dba. I use some previous answers to check available space and I still have a lot of space. However, after reducing the full table scan as many as possible. The problem is solved. My guess is that Oracle uses temp table to store the full table scan data. It the data size exceeds the limit, it will show the error. Hope this helps someone with the same issue

pid_t child_pid, wpid;
int status = 0;

//Father code (before child processes start)

for (int id=0; id<n; id++) {
    if ((child_pid = fork()) == 0) {
        //child code
        exit(0);
    }
}

while ((wpid = wait(&status)) > 0); // this way, the father waits for all the child processes 

//Father code (After all child processes end)

wait waits for a child process to terminate, and returns that child process's pid. On error (eg when there are no child processes), -1 is returned. So, basically, the code keeps waiting for child processes to finish, until the waiting errors out, and then you know they are all finished.

That's desired behavior, you should define the model in the controller, not in the view.

<div ng-controller="Main">
  <input type="text" ng-model="rootFolders">
</div>


function Main($scope) {
  $scope.rootFolders = 'bob';
}

The reason DISTINCT and GROUP BY work on entire rows is that your query returns entire rows.

To help you understand: Try to write out by hand what the query should return and you will see that it is ambiguous what to put in the non-duplicated columns.

If you literally don't care what is in the other columns, don't return them. Returning a random row for each e-mail address seems a little useless to me.

By dynamically allocating a Movie object with new Movie(), you get a pointer to the new object. You do not need a second vector for the movies, just store the pointers and you can access them. Like Brian wrote, the vector would be defined as

std::vector<Movie *> movies

But be aware that the vector will not delete your objects afterwards, which will result in a memory leak. It probably doesn't matter for your homework, but normally you should delete all pointers when you don't need them anymore.

Expand your one liner into multiple lines. Then it becomes easy:

f.write(re.split("Tech ID:|Name:|Account #:",line)[-1])

parts = re.split("Tech ID:|Name:|Account #:",line)
wanted_part = parts[-1]
wanted_part_stripped = wanted_part.strip()
f.write(wanted_part_stripped)

We don't need to bother entering the current line number.

If you would like to change each foo to bar for current line (.) and the two next lines (+2), simply do:

:.,+2s/foo/bar/g

If you want to confirm before changes are made, replace g with gc:

:.,+2s/foo/bar/gc

Possible Cause #1 (same as the first 3 answers for this question): Project Structure Settings

1. File > Project Structure > Under Project Settings, go to Project > set Project SDK to 1.8 (with version 65 or above, latest is 112) and set Project Language Level to 8.

If the above does not work, check the target bytecode version of your compiler and move on to Possible Cause #2.

Possible Cause #2: Compiler

The reason it is throwing that exception is because you have the argument rb, which opens the file in binary mode. Change that to r, which will by default open the file in text mode.

Your code:

import csv
ifile  = open('sample.csv', "rb")
read = csv.reader(ifile)
for row in read :
    print (row) 

New code:

import csv
ifile  = open('sample.csv', "r")
read = csv.reader(ifile)
for row in read :
    print (row)

A Daemon is just program that runs as a background process, rather than being under the direct control of an interactive user...

[The below bash code is for Debian systems - Ubuntu, Linux Mint distros and so on]

The simple way:

The simple way would be to edit your /etc/rc.local file and then just have your script run from there (i.e. everytime you boot up the system):

sudo nano /etc/rc.local

Add the following and save:

#For a BASH script
/bin/sh TheNameOfYourScript.sh > /dev/null &

The better way to do this would be to create a Daemon via Upstart:

sudo nano /etc/init/TheNameOfYourDaemon.conf

add the following:

description "My Daemon Job"
author "Your Name"
start on runlevel [2345]    

pre-start script
  echo "[`date`] My Daemon Starting" >> /var/log/TheNameOfYourDaemonJobLog.log
end script

exec /bin/sh TheNameOfYourScript.sh > /dev/null &

Save this.

Confirm that it looks ok:

init-checkconf /etc/init/TheNameOfYourDaemon.conf

Now reboot the machine:

sudo reboot

Now when you boot up your system, you can see the log file stating that your Daemon is running:

cat  /var/log/TheNameOfYourDaemonJobLog.log

• Now you may start/stop/restart/get the status of your Daemon via:

restart: this will stop, then start a service

sudo service TheNameOfYourDaemonrestart restart

start: this will start a service, if it's not running

sudo service TheNameOfYourDaemonstart start

stop: this will stop a service, if it's running

sudo service TheNameOfYourDaemonstop stop

status: this will display the status of a service

sudo service TheNameOfYourDaemonstatus status

Send a POST request with content type = 'form-data':

import requests
files = {
    'username': (None, 'myusername'),
    'password': (None, 'mypassword'),
}
response = requests.post('https://example.com/abc', files=files)

Beautiful Soup 4 allows you to set a formatter to your output

If you pass in formatter=None, Beautiful Soup will not modify strings at all on output. This is the fastest option, but it may lead to Beautiful Soup generating invalid HTML/XML, as in these examples:

print(soup.prettify(formatter=None))
# <html>
#  <body>
#   <p>
#    Il a dit <<Sacré bleu!>>
#   </p>
#  </body>
# </html>

link_soup = BeautifulSoup('<a href="http://example.com/?foo=val1&bar=val2">A link</a>')
print(link_soup.a.encode(formatter=None))
# <a href="http://example.com/?foo=val1&bar=val2">A link</a>

There are a few ways to do this it seems.

Option 1: Native Angular

Angular provides an $anchorScroll service, but the documentation is severely lacking and I've not been able to get it to work.

Check out http://www.benlesh.com/2013/02/angular-js-scrolling-to-element-by-id.html for some insight into $anchorScroll.

Option 2: Custom Directive / Native JavaScript

Another way I tested out was creating a custom directive and using el.scrollIntoView(). This works pretty decently by basically doing the following in your directive link function:

var el = document.getElementById(attrs.href);
el.scrollIntoView();

However, it seems a bit overblown to do both of these when the browser natively supports this, right?

Option 3: Angular Override / Native Browser

If you take a look at http://docs.angularjs.org/guide/dev_guide.services.$location and its HTML Link Rewriting section, you'll see that links are not rewritten in the following:

Links that contain target element

Example: <a href="/ext/link?a=b" target="_self">link</a>

So, all you have to do is add the target attribute to your links, like so:

<a href="#anchorLinkID" target="_self">Go to inpage section</a>

Angular defaults to the browser and since its an anchor link and not a different base url, the browser scrolls to the correct location, as desired.

I went with option 3 because its best to rely on native browser functionality here, and saves us time and effort.

Gotta note that after a successful scroll and hash change, Angular does follow up and rewrite the hash to its custom style. However, the browser has already completed its business and you are good to go.

Dependency Walker tells all(well almost). http://www.dependencywalker.com/

It does not "install" -just get it, extract it and run the exec. It works for any x32 or x64 windows module|application.

As I recall it is fairly straightforward to see all dependencies, i.e. the dll modules, and since the appl. is a sum of the dependencies one can ascertain if it is full x64, x32(x86) or a bit of each.

Type of CPU that the module was built for is in the "CPU" column. Most 64-bit aps are still a bit of each but 32-bit ap w/b all x86.

Beautiful program for geeks/programmers and it is free...

In case you need something simple without wanting to extend the Array prototype:

// Example array
var array = [{id: 1}, {id: 2}, {id: 3}];

function pushIfNew(obj) {
  for (var i = 0; i < array.length; i++) {
    if (array[i].id === obj.id) { // modify whatever property you need
      return;
    }
  }
  array.push(obj);
}

You can use generic code inspection via instanceof:

var e = document.getElementById('#my-element');
if (e instanceof HTMLInputElement) {}         // <input>
elseif (e instanceof HTMLSelectElement) {}    // <select>
elseif (e instanceof HTMLTextAreaElement) {}  // <textarea>
elseif (  ... ) {}                            // any interface

Look here for a complete list of interfaces.

i'm not too experienced with open cv but if you want the code in the for loop to be called when a key is pressed, you can use a while loop and an raw_input and a condition to prevent the loop from executing forever

import cv2

camera = cv2.VideoCapture(0)
i = 0
while i < 10:
    raw_input('Press Enter to capture')
    return_value, image = camera.read()
    cv2.imwrite('opencv'+str(i)+'.png', image)
    i += 1
del(camera)

I got this error quite a lot, so now I do a batch removal of all unused containers at once:

docker container prune 

add -f to force removal without prompt.

To list all unused containers (without removal):

docker container ls -a --filter status=exited --filter status=created 

See here more examples how to prune other objects (networks, volumes, etc.).

As per comments, First you need to install an instance of SQL Server if you don't already have one - https://msdn.microsoft.com/en-us/library/ms143219.aspx

Once this is installed you must connect to this instance (server) and then you can create a database here - https://msdn.microsoft.com/en-US/library/ms186312.aspx

"Server unable to read htaccess file" means just that. Make sure that the permissions on your .htaccess file are world-readable.

In confing.yml

1. Go to home
2. Open .bashrc

3. Create alias at bottom of the file

   alias alias_name='command to do'
   eg: alias cdDesktop='cd /Desktop'
   

4. Save the file

5. source .bashrc

   source ~/.bashrc
   

6. Open terminal (Ctrl+Alt+T) & type cdDesktop & press enter

Something like this? Haven't tested it but should work fine.

function magic($obj, $var, $value = NULL)
{
    if($value == NULL)
    {
        return $obj->$var;
    }
    else
    {
        $obj->$var = $value;
    }
}

I thought this would work, based on this source.

SELECT
  'Currently, ' 
  || (SELECT COUNT(*) FROM V$SESSION)
  || ' out of ' 
  || DECODE(VL.SESSIONS_MAX,0,'unlimited',VL.SESSIONS_MAX) 
  || ' connections are used.' AS USAGE_MESSAGE

  V$LICENSE VL

However, Justin Cave is right. This query gives better results:

SELECT
  'Currently, ' 
  || (SELECT COUNT(*) FROM V$SESSION)
  || ' out of ' 
  || VP.VALUE 
  || ' connections are used.' AS USAGE_MESSAGE
FROM

In case anyone needed the above in swift :

SWIFT 3.0 and above :

this will capitalize your string, make the first letter capital :

viewNoteDateMonth.text  = yourString.capitalized

this will uppercase your string, make all the string upper case :

viewNoteDateMonth.text  = yourString.uppercased()

I've recently stumbled upon the following solution to this problem:

Source: Multiple versions of Chrome

...this is registry data problem: How to do it then (this is an example for 2.0.172.39 and 3.0.197.11, I'll try it with next versions as they will come, let's assume I've started with Chrome 2):

1. Install Chrome 2, you'll find it Application Data folder, since I'm from Czech Republic and my name is Bronislav Klucka the path looks like this:

   C:\Documents and Settings\Bronislav Klucka\Local Settings\Data aplikací\Google\Chrome
   

   and run Chrome

2. Open registry and save

   [HKEY_CURRENT_USER\Software\Google\Update\Clients\{8A69D345-D564-463c-AFF1-A69D9E530F96}]
   [HKEY_CURRENT_USER\Software\Google\Update\ClientState\{8A69D345-D564-463c-AFF1-A69D9E530F96}]
   

   keys, put them into one chrome2.reg file and copy this file next to chrome.exe (ChromeDir\Application)

3. Rename Chrome folder to something else (e.g. Chrome2)

4. Install Chrome 3, it will install to Chrome folder again and run Chrome

5. Save the same keys (there are changes due to different version) and save it to the chrome3.reg file next to chrome.exe file of this new version again

6. Rename the folder again (e.g. Chrome3)

   the result would be that there is no Chrome dir (only Chrome2 and Chrome3)

7. Go to the Application folder of Chrome2, create chrome.bat file with this content:

   @echo off
   regedit /S chrome2.reg
   START chrome.exe -user-data-dir="C:\Docume~1\Bronis~1\LocalS~1\Dataap~1\Google\Chrome2\User Data"
   rem START chrome.exe -user-data-dir="C:\Documents and Settings\Bronislav Klucka\Local Settings\Data aplikací\Google\Chrome2\User Data"
   

   the first line is generic batch command, the second line will update registry with the content of chrome2.reg file, the third lines starts Chrome pointing to passed directory, the 4th line is commented and will not be run.

   Notice short name format passed as -user-data-dir parameter (the full path is at the 4th line), the problem is that Chrome using this parameter has a problem with diacritics (Czech characters)

8. Do 7. again for Chrome 3, update paths and reg file name in bat file for Chrome 3

Try running both bat files, seems to be working, both versions of Chrome are running simultaneously.

Updating: Running "About" dialog displays correct version, but an error while checking for new one. To correct that do (I'll explain form Chrome2 folder): 1. rename Chrome2 to Chrome 2. Go to Chrome/Application folder 3. run chrome2.reg file 4. run chrome.exe (works the same for Chrome3) now the version checking works. There has been no new version of Chrome since I've find this whole solution up. But I assume that update will be downloaded to this folder so all you need to do is to update reg file after update and rename Chrome folder back to Chrome2. I'll update this post after successful Chrome update.

Another option would be use a dictionary instead of an array:

Dim oNames As Object
Set oNames = CreateObject("Scripting.Dictionary")
'You could if need be create this automatically from an existing Array
'The 1 is just a dummy value, we just want the names as keys
oNames.Add "JOHN", 1
oNames.Add "BOB", 1
oNames.Add "JAMES", 1
oNames.Add "PHILIP", 1

As this would then get you a one-liner of

oNames.Exists("JOHN")

The advantage a dictionary provides is exact matching over partial matching from Filter. Say if you have the original list of names in an Array, but were looking for "JO" or "PHIL" who were actually two new people in addition to the four we started with. In this case, Filter(oNAMES, "JO") will match "JOHN" which may not be desired. With a dictionary, it won't.

Click "View Detail..." a window will open where you can expand the "Inner Exception" my guess is that when you try to delete the record there is a reference constraint violation. The inner exception will give you more information on that so you can modify your code to remove any references prior to deleting the record.

lsof -t -i tcp:8000 | xargs kill -9

I'm particularly fond of this date picker built for Mootools: http://electricprism.com/aeron/calendar/

It's lovely right out of the box.

net stop <your service> && net start <your service>

No net restart, unfortunately.

It is used in the stack unwiding tables, which you can see for instance in the assembly output of my answer to another question. As mentioned on that answer, its use is defined by the Itanium C++ ABI, where it is called the Personality Routine.

The reason it "works" by defining it as a global NULL void pointer is probably because nothing is throwing an exception. When something tries to throw an exception, then you will see it misbehave.

Of course, if nothing is using exceptions, you can disable them with -fno-exceptions (and if nothing is using RTTI, you can also add -fno-rtti). If you are using them, you have to (as other answers already noted) link with g++ instead of gcc, which will add -lstdc++ for you.

The -L merely gives the path where to find the .a or .so file. What you're looking for is to add -lmine to the LIBS variable.

Make that -static -lmine to force it to pick the static library (in case both static and dynamic library exist).

Addition: Suppose the path to the file has been conveyed to the linker (or compiler driver) via -L you can also specifically tell it to link libfoo.a by giving -l:libfoo.a. Note that in this case the name includes the conventional lib-prefix. You can also give a full path this way. Sometimes this is the better method to "guide" the linker to the right location.

The use of cron on OS X is discouraged. launchd is used instead. Try man launchctl to get started. You have to create special XML files that define your jobs and put them in a special place with certain permissions.

You'll usually just need to figure out launchctl load

http://developer.apple.com/library/mac/#documentation/Darwin/Reference/ManPages/man1/launchctl.1.html

If you really do want to use cron on OS X, check out this answer: https://superuser.com/a/243944/2449

i solved this in a shorter fashion.

Dim marray() as variant, array2() as variant, YY ,ZZ as integer
YY=1
ZZ=1

Redim marray(1 to 1000, 1 to 10)
Do while ZZ<100 ' this is populating the first array
marray(ZZ,YY)= "something"
ZZ=ZZ+1
YY=YY+1 
Loop
'this part is where you store your array in another then resize and restore to original
array2= marray
Redim marray(1 to ZZ-1, 1 to YY)
marray = array2

It will be faster to just make a HEAD request so no HTML will be fetched.
Also I am sure google would like it better this way :)

try:
    import httplib
except:
    import http.client as httplib

def have_internet():
    conn = httplib.HTTPConnection("www.google.com", timeout=5)
    try:
        conn.request("HEAD", "/")
        conn.close()
        return True
    except:
        conn.close()
        return False

I've updated Eric D's answer for Swift 5:

 func convertStringToDictionary(text: String) -> [String:AnyObject]? {
    if let data = text.data(using: .utf8) {
        do {
            let json = try JSONSerialization.jsonObject(with: data, options: .mutableContainers) as? [String:AnyObject]
            return json
        } catch {
            print("Something went wrong")
        }
    }
    return nil
}

When working with async functions or observables provided by 3rd party libraries, for example Cloud firestore, I've found functions the waitFor method shown below (TypeScript, but you get the idea...) to be helpful when you need to wait on some process to complete, but you don't want to have to embed callbacks within callbacks within callbacks nor risk an infinite loop.

This method is sort of similar to a while (!condition) sleep loop, but yields asynchronously and performs a test on the completion condition at regular intervals till true or timeout.

export const sleep = (ms: number) => {
    return new Promise(resolve => setTimeout(resolve, ms))
}
/**
 * Wait until the condition tested in a function returns true, or until 
 * a timeout is exceeded.
 * @param interval The frenequency with which the boolean function contained in condition is called.
 * @param timeout  The maximum time to allow for booleanFunction to return true
 * @param booleanFunction:  A completion function to evaluate after each interval. waitFor will return true as soon as the completion function returns true.   
 */
export const waitFor = async function (interval: number, timeout: number,
    booleanFunction: Function): Promise<boolean> {
    let elapsed = 1;
    if (booleanFunction()) return true;
    while (elapsed < timeout) {
        elapsed += interval;
        await sleep(interval);
        if (booleanFunction()) {
            return true;
        }
    }
    return false;
}

The say you have a long running process on your backend you want to complete before some other task is undertaken. For example if you have a function that totals a list of accounts, but you want to refresh the accounts from the backend before you calculate, you can do something like this:

async recalcAccountTotals() : number {
     this.accountService.refresh();   //start the async process.
     if (this.accounts.dirty) {
           let updateResult = await waitFor(100,2000,()=> {return !(this.accounts.dirty)})
     }
 if(!updateResult) { 
      console.error("Account refresh timed out, recalc aborted");
      return NaN;
    }
 return ... //calculate the account total. 
}

Another alternative is to use a markdown editor like StackEdit. It converts html (or text) into markdown in a WYSIWYG editor. You can create indents, titles, lists in the editor, and it will show you the corresponding text in markdown format. You can then save, publish, share, or download the file. You can access it on their website - no downloads required!

function func(a, b)
{
  if (typeof a == 'undefined')
    a = 10;
  if (typeof b == 'undefined')
    b = 20;
  // do what you want ... for example
  alert(a + ',' + b);
}

in shorthand

function func(a, b)
{
  a = (typeof a == 'undefined')?10:a;
  b = (typeof b == 'undefined')?20:b;

  // do what you want ... for example
  alert(a + ',' + b);
}

I've also had good results with Eclipse and Pydev. Although I still require a shell opened to the project directory to run manage.py commands. I've also been using it with the Bazaar plugin for revision control and syncing code with the server.

You can convert the SecretKey to a byte array (byte[]), then Base64 encode that to a String. To convert back to a SecretKey, Base64 decode the String and use it in a SecretKeySpec to rebuild your original SecretKey.

For Java 8

SecretKey to String:

// create new key
SecretKey secretKey = KeyGenerator.getInstance("AES").generateKey();
// get base64 encoded version of the key
String encodedKey = Base64.getEncoder().encodeToString(secretKey.getEncoded());

String to SecretKey:

// decode the base64 encoded string
byte[] decodedKey = Base64.getDecoder().decode(encodedKey);
// rebuild key using SecretKeySpec
SecretKey originalKey = new SecretKeySpec(decodedKey, 0, decodedKey.length, "AES"); 

For Java 7 and before (including Android):

NOTE I: you can skip the Base64 encoding/decoding part and just store the byte[] in SQLite. That said, performing Base64 encoding/decoding is not an expensive operation and you can store strings in almost any DB without issues.

NOTE II: Earlier Java versions do not include a Base64 in one of the java.lang or java.util packages. It is however possible to use codecs from Apache Commons Codec, Bouncy Castle or Guava.

SecretKey to String:

// CREATE NEW KEY
// GET ENCODED VERSION OF KEY (THIS CAN BE STORED IN A DB)

    SecretKey secretKey;
    String stringKey;

    try {secretKey = KeyGenerator.getInstance("AES").generateKey();}
    catch (NoSuchAlgorithmException e) {/* LOG YOUR EXCEPTION */}

    if (secretKey != null) {stringKey = Base64.encodeToString(secretKey.getEncoded(), Base64.DEFAULT)}

String to SecretKey:

// DECODE YOUR BASE64 STRING
// REBUILD KEY USING SecretKeySpec

    byte[] encodedKey     = Base64.decode(stringKey, Base64.DEFAULT);
    SecretKey originalKey = new SecretKeySpec(encodedKey, 0, encodedKey.length, "AES");

One thing that could have happened:

• 1: you create your serialized data with a given library A (version X)
• 2: you then try to read this data with the same library A (but version Y)

Hence, at compile time for the version X, the JVM will generate a first Serial ID (for version X) and it will do the same with the other version Y (another Serial ID).

When your program tries to de-serialize the data, it can't because the two classes do not have the same Serial ID and your program have no guarantee that the two Serialized objects correspond to the same class format.

Assuming you changed your constructor in the mean time and this should make sense to you.

Very simple...

1- just grab activity by getActivity() in the fragment

2- then call finish();

So just getActivity().finish(); will finish the parent activity.

One more trick for controller event listeners.

You can use wildcards to watch for an event from any component:

this.control({
   '*':{ 
       myCustomEvent: this.doSomething
   }
});

For Chrome:

1. Set your email manager to Gmail

1. Write mailto: in the address bar and press enter.

Easier:

1. Edit search engines:

1. Write mt and enter in address bar.

I had this issue in a .net 4 web forms vs2010 project and tried everything mentioned on this page. Ended up removing and adding global.asax actually resolved the issue for me.

I have used graphviz ( https://www.graphviz.org/gallery ) together with LaTeX using dot command to generate graphs in PDF and includegraphics to include those.

If graphviz produces what you are aiming at, this might be the best way to integrate: dot2tex: https://ctan.org/pkg/dot2tex?lang=en

You can use some thing like this

  is a HTML entity. When doing .text(), all HTML entities are decoded to their character values.

Instead of comparing using the entity, compare using the actual raw character:

var x = td.text();
if (x == '\xa0') { // Non-breakable space is char 0xa0 (160 dec)
  x = '';
}

Or you can also create the character from the character code manually it in its Javascript escaped form:

var x = td.text();
if (x == String.fromCharCode(160)) { // Non-breakable space is char 160
  x = '';
}

More information about String.fromCharCode is available here:

fromCharCode - MDC Doc Center

More information about character codes for different charsets are available here:

after is now a JavaScript method

MDN Documentation

Quoting MDN

The ChildNode.after() method inserts a set of Node or DOMString objects in the children list of this ChildNode's parent, just after this ChildNode. DOMString objects are inserted as equivalent Text nodes.

The browser support is Chrome(54+), Firefox(49+) and Opera(39+). It doesn't support IE and Edge.

Snippet

var elm=document.getElementById('div1');
var elm1 = document.createElement('p');
var elm2 = elm1.cloneNode();
elm.append(elm1,elm2);

//added 2 paragraphs
elm1.after("This is sample text");
//added a text content
elm1.after(document.createElement("span"));
//added an element
console.log(elm.innerHTML);

<div id="div1"></div>

In the snippet, I used another term append too

Try putting this in the constructor of whatever control is housing your textbox:

Loaded += (sender, e) =>
{
    MoveFocus(new TraversalRequest(FocusNavigationDirection.Next));
    myTextBox.SelectAll();
}

Reviving an old thread, but this pretty clean approach was not listed.

function mycommand() {
    ssh [email protected] <<+
    cd testdir;./test.sh "$1"
+
}

ID attributes cannot start with a number and they should be unique. In any case, you can use :eq() to select a specific row using a 0-based integer:

// Remove the third row
$("#test tr:eq(2)").remove();

Alternatively, rewrite your HTML so that it's valid:

<table id="test">
 <tr id=test1><td>bla</td></tr>
 <tr id=test2><td>bla</td></tr>
 <tr id=test3><td>bla</td></tr>
 <tr id=test4><td>bla</td></tr>
</table>

And remove it referencing just the id:

$("#test3").remove();

I've personally always used boost.regex (although I don't have much need for regex in C++). Microsoft Labs has a regex library too, called GRETA: http://research.microsoft.com/projects/greta/. Apparently it's very fast and features a whole Perl 5 syntax. I haven't used it, but you may want to test it out.

I tried your code and got a top rounded corner button. I gave the colors as @ffffff and stroke I gave #C0C0C0.

try

1. Giving android : bottomLeftRadius="0.1dp" instead of 0. if its not working
2. Check in what drawable and the emulator's resolution. I created a drawable folder under res and using it. (hdpi, mdpi ldpi) the folder you have this XML. this is my output.

To expand a bit on Hossein Narimani Rad's answer, you can rename both a table and columns using System.ComponentModel.DataAnnotations.Schema.TableAttribute and System.ComponentModel.DataAnnotations.Schema.ColumnAttribute respectively.

This has a couple benefits:

1. Not only will this create the the name migrations automatically, but
2. it will also deliciously delete any foreign keys and recreate them against the new table and column names, giving the foreign keys and constaints proper names.
3. All this without losing any table data

For example, adding [Table("Staffs")]:

[Table("Staffs")]
public class AccountUser
{
    public long Id { get; set; }

    public long AccountId { get; set; }

    public string ApplicationUserId { get; set; }

    public virtual Account Account { get; set; }

    public virtual ApplicationUser User { get; set; }
}

Will generate the migration:

    protected override void Up(MigrationBuilder migrationBuilder)
    {
        migrationBuilder.DropForeignKey(
            name: "FK_AccountUsers_Accounts_AccountId",

Just add Axios.defaults.withCredentials=true instead of ({credentials: true}) in client side, and change app.use(cors()) to

app.use(cors(
  {origin: ['your client side server'],
  methods: ['GET', 'POST'],
  credentials:true,
}
))

I had same problem, my issue was that downloaded Apache 2.4 but 32 bits. Then re-download 64bits version and it's works.

I hope it helps you

It doesn't work because it's syntactically nonsensical. You simply can't do that in JavaScript like that.

You can, however, use jQuery:

  if ($(this).is('[href$=?]'))

You can also just look at the "href" value:

  if (/\?$/.test(this.href))

I am afraid the body of your question is unrelated to title question.

If to answer the title:

In SQL, is UPDATE always faster than DELETE+INSERT?

then answer is NO!

Just google for

• "Expensive direct update"* "sql server"
• "deferred update"* "sql server"

Such update(s) result in more costly (more processing) realization of update through insert+update than direct insert+update. These are the cases when

• one updates the field with unique (or primary) key or
• when the new data does not fit (is bigger) in the pre-update row space allocated (or even maximum row size),resulting in fragmentation,
• etc.

My fast (non-exhaustive) search, not pretending to be covering one, gave me [1], [2]

You can use scroll-behavior: smooth; to get this done without Javascript

https://developer.mozilla.org/en-US/docs/Web/CSS/scroll-behavior

I've tried various combinations and had them fail in FireFox. It has been a while so the answer above may work fine or I may have missed something.

What has always worked for me is to add the following to the head of each page, or the template (Master Page in .net).

<script language="javascript" type="text/javascript">
    window.onbeforeunload = function () {   
        // This function does nothing.  It won't spawn a confirmation dialog   
        // But it will ensure that the page is not cached by the browser.
    }  
</script>

This has disabled all caching in all browsers for me without fail.

Basically, it will make your code a lot easier to compile under other compilers which also implement the ANSI standard, and, if you are careful in which libraries/api calls you use, under other operating systems/platforms.

The first one, turns off SPECIFIC features of GCC. (-ansi) The second one, will complain about ANYTHING at all that does not adhere to the standard (not only specific features of GCC, but your constructs too.) (-pedantic).

Here is a detailed information on setting up Java and its paths on CentOS6.

Below steps are for the installation of latest Java version 8:

1. Download java rpm package from Oracle site. (jdk-8-linux-x64.rpm)
2. Install from the rpm. (rpm -Uvh jdk-8-linux-x64.rpm)
3. Open /etc/profile, and set the java paths, save it.
4. Check the java installation path, and java version, with the commands: which java, java -version

Now you can test the installation with a sample java program

UPDATE tablename SET fieldname = CONCAT("test", fieldname) [WHERE ...]

You can try configure SQL server:

1. Step 1: Open SQL server 20xx Configuration Manager
2. Step 2: Click Protocols for SQL.. in SQL server configuration. Then, right click TCP/IP, choose Properties
3. Step 3: Click tab IP Address, Edit All TCP. Port is 1433

NOTE: ALL TCP port is 1433 Finally, restart the server.

I know this is a really old question but it is also one that is still relevant, though these days applies only to mozilla. (I have no idea what explorer does coz we don't code for non standard browsers).

Chrome is well behaved if one includes an icon tag in the header.

Although mozilla are well aware of the issue, as usual, they never fix the annoying small stuff. Even 6 years later.

So, there are two ways of forcing an icon refresh with firefox.

1. Have all your clients uninstall firefox. Then re-install.

2. Manually type just the domain in the url bar - do not use http or www just the domain (mydomain.com).

This assumes of course that your ns records include resolution for the domain name only.

test -z returns true if the parameter is empty (see man sh or man test).

There exist somewhere another java.exe from jre version 1.8 that it is in "path" you should find and delete it if it is possible. it may be in user tempdata for applications that need jre.

Description

There are many ways to validate your TextBox. You can do this on every keystroke, at a later time, or on the Validating event.

The Validating event gets fired if your TextBox looses focus. When the user clicks on a other Control, for example. If your set e.Cancel = true the TextBox doesn't lose the focus.

MSDN - Control.Validating Event When you change the focus by using the keyboard (TAB, SHIFT+TAB, and so on), by calling the Select or SelectNextControl methods, or by setting the ContainerControl.ActiveControl property to the current form, focus events occur in the following order

Enter

GotFocus

Leave

Validating

Validated

LostFocus

When you change the focus by using the mouse or by calling the Focus method, focus events occur in the following order:

Enter

GotFocus

LostFocus

Leave

Validating

Validated

Sample Validating Event

private void textBox1_Validating(object sender, CancelEventArgs e)
{
    if (textBox1.Text != "something")
        e.Cancel = true;
}

Update

You can use the ErrorProvider to visualize that your TextBox is not valid. Check out Using Error Provider Control in Windows Forms and C#

I didn't want to have to have the YouTube app present on the device so I used this tutorial:

http://www.viralandroid.com/2015/09/how-to-embed-youtube-video-in-android-webview.html

...to produce this code in my app:

WebView mWebView; 

@Override
public void onCreate(Bundle savedInstanceState) {
    setContentView(R.layout.video_webview);
    mWebView=(WebView)findViewById(R.id.videoview);

    //build your own src link with your video ID
    String videoStr = "<html><body>Promo video<br><iframe width=\"420\" height=\"315\" src=\"https://www.youtube.com/embed/47yJ2XCRLZs\" frameborder=\"0\" allowfullscreen></iframe></body></html>";

    mWebView.setWebViewClient(new WebViewClient() {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
                return false;
        }
    });
    WebSettings ws = mWebView.getSettings();
    ws.setJavaScriptEnabled(true);
    mWebView.loadData(videoStr, "text/html", "utf-8");

    android:layout_height="wrap_content"
    />  
</LinearLayout>     

This worked just how I wanted it. It doesn't autoplay but the video streams within my app. Worth noting that some restricted videos won't play when embedded.

A more raw approach without using sort Arrays.sort method. This is using insertion sort.

public static void main(String[] args){
    String wordSt="watch";
    char[] word=wordSt.toCharArray();

    for(int i=0;i<(word.length-1);i++){
        for(int j=i+1;j>0;j--){
            if(word[j]<word[j-1]){
                char temp=word[j-1];
                word[j-1]=word[j];
                word[j]=temp;
            }
        }
    }
    wordSt=String.valueOf(word);
    System.out.println(wordSt);
}

The "Lines" property of a TextBox is an array of strings. By definition, you cannot add elements to an existing string[], like you can to a List<string>. There is simply no method available for the purpose. You must instead create a new string[] based on the current Lines reference, and assign it to Lines.

Using a little Linq (.NET 3.5 or later):

textBox1.Lines = textBox.Lines.Concat(new[]{"Some Text"}).ToArray();

This code is fine for adding one new line at a time based on user interaction, but for initializing a textbox with a few dozen new lines, it will perform very poorly. If you're setting the initial value of a TextBox, I would either set the Text property directly using a StringBuilder (as other answers have mentioned), or if you're set on manipulating the Lines property, use a List to compile the collection of values and then convert it to an array to assign to Lines:

var myLines = new List<string>();

myLines.Add("brown");
myLines.Add("brwn");
myLines.Add("brn");
myLines.Add("brow");
myLines.Add("br");
myLines.Add("brw");
...

textBox1.Lines = myLines.ToArray();

Even then, because the Lines array is a calculated property, this involves a lot of unnecessary conversion behind the scenes.

url isn't an object on the Marker class. But there's nothing stopping you adding that as a property to that class. I'm guessing whatever example you were looking at did that too. Do you want a different URL for each marker? What happens when you do:

for (var i = 0; i < locations.length; i++) 
{
    var flag = new google.maps.MarkerImage('markers/' + (i + 1) + '.png',
      new google.maps.Size(17, 19),
      new google.maps.Point(0,0),
      new google.maps.Point(0, 19));
    var place = locations[i];
    var myLatLng = new google.maps.LatLng(place[1], place[2]);
    var marker = new google.maps.Marker({
        position: myLatLng,
        map: map,
        icon: flag,
        shape: shape,
        title: place[0],
        zIndex: place[3],
        url: "/your/url/"
    });

    google.maps.event.addListener(marker, 'click', function() {
        window.location.href = this.url;
    });
}

TypeScript 2.0 has the readonly modifier:

class MyClass {
    readonly myReadOnlyProperty = 1;

    myMethod() {
        console.log(this.myReadOnlyProperty);
        this.myReadOnlyProperty = 5; // error, readonly
    }
}

new MyClass().myReadOnlyProperty = 5; // error, readonly

It's not exactly a constant because it allows assignment in the constructor, but that's most likely not a big deal.

Alternative Solution

An alternative is to use the static keyword with readonly:

class MyClass {
    static readonly myReadOnlyProperty = 1;

    constructor() {
        MyClass.myReadOnlyProperty = 5; // error, readonly
    }

    myMethod() {
        console.log(MyClass.myReadOnlyProperty);
        MyClass.myReadOnlyProperty = 5; // error, readonly
    }
}

MyClass.myReadOnlyProperty = 5; // error, readonly

This has the benefit of not being assignable in the constructor and only existing in one place.

When running Nginx in a Docker container, be aware that a volume mounted over the log dir defeats the purpose of creating a softlink between the log files and stdout/stderr in your Dockerfile, as described in @Boeboe 's answer.

In that case you can either create the softlink in your entrypoint (executed after volumes are mounted) or not use a volume at all (e.g. when logs are already collected by a central logging system).

I finally was able to insert a row, on the condition that it didn't already exist, using the following model:

INSERT INTO table ( column1, column2, column3 )
(
    SELECT $column1, $column2, $column3
      WHERE NOT EXISTS (
        SELECT 1
          FROM table 
          WHERE column1 = $column1
          AND column2 = $column2
          AND column3 = $column3 
    )
)

which I found at:

http://www.postgresql.org/message-id/[email protected]

I faced this issue, and resolved this issue using getchar() to catch the ('\n') new char

$('#baba option:first').attr('selected',true);

I found this solution where you can simply, check the server response code using status code.

Example :

$.ajax({
type : "POST",
url : "/package/callApi/createUser",
data : JSON.stringify(data),
contentType: "application/json; charset=UTF-8",
success: function (response) {  
    alert("Account created");
},
statusCode: {
    403: function() {
       // Only if your server returns a 403 status code can it come in this block. :-)
        alert("Username already exist");
    }
},
error: function (e) {
    alert("Server error - " + e);
} 
});

Reference to HEAD is not necessary.

git checkout -- file.js is sufficient

1. There is no such thing as xhr.file = file;; the file object is not supposed to be attached this way.

2. xhr.send(file) doesn't send the file. You have to use the FormData object to wrap the file into a multipart/form-data post data object:

   var formData = new FormData();
   formData.append("thefile", file);
   xhr.send(formData);
   

After that, the file can be access in $_FILES['thefile'] (if you are using PHP).

Remember, MDC and Mozilla Hack demos are your best friends.

EDIT: The (2) above was incorrect. It does send the file, but it would send it as raw post data. That means you would have to parse it yourself on the server (and it's often not possible, depend on server configuration). Read how to get raw post data in PHP here.

The JIT Compiler is probably going to make this pretty fast since it's just branches and basic tests. You could probably make it more elegant with a HashMap lookup to a callback but I doubt it would be any faster. As to memory, this is pretty slim as is.

Somehow I doubt this code is actually a critical bottle neck for memory or performance. Do you have any real reason to try to optimize it?

This was pretty well answered over here: How to make a YouTube embedded video a full page width one?

If you add '?rel=0&autoplay=1' to the end of the url in the embed code (like this)

<iframe id="video" src="//www.youtube.com/embed/5iiPC-VGFLU?rel=0&autoplay=1" frameborder="0" allowfullscreen></iframe>

of the video it should play on load. Here's a demo over at jsfiddle.

(Swift 3) Add text box and uipickerview to the storyboard then add delegate and data source to uipickerview and add delegate to textbox. Follow video for assistance https://youtu.be/SfjZwgxlwcc

import UIKit

    @IBOutlet weak var textBox: UITextField!
    @IBOutlet weak var dropDown: UIPickerView!

    var list = ["1", "2", "3"]

    public func numberOfComponents(in pickerView: UIPickerView) -> Int{

    func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {

        self.view.endEditing(true)

        if textField == self.textBox {
            self.dropDown.isHidden = false
            //if you don't want the users to se the keyboard type:

[ round(x,2) for x in [2.15295647e+01, 8.12531501e+00, 3.97113829e+00, 1.00777250e+01]]

Your 2nd attempt will work perfectly, and is actually a really good way to handle variable names that you want to have available globally. But you have a name error in the last line. Here is how it should be:

# ../myproject/main.py

# Import globfile    
import globfile

# Save myList into globfile
globfile.myList = []

# Import subfile
import subfile

# Do something
subfile.stuff()
print(globfile.myList[0])

See the last line? myList is an attr of globfile, not subfile. This will work as you want.

grep -Po 'potato:\s\K.*' file

-P to use Perl regular expression

-o to output only the match

\s to match the space after potato:

\K to omit the match

.* to match rest of the string(s)

You can use a post-commit hook.

Put the post-commit hook script in the hooks folder, create a wget_folder in your C:\ drive, and put the wget.exe file in this folder. Add the following code in the file called post-commit.bat

SET REPOS=%1   
SET REV=%2

FOR /f "tokens=*" %%a IN (  
'svnlook uuid %REPOS%'  
) DO (  
SET UUID=%%a  
)  

FOR /f "tokens=*" %%b IN (  
'svnlook changed --revision %REV% %REPOS%'  
) DO (  
SET POST=%%b   
)

echo %REPOS% ----- 1>&2

echo %REV% -- 1>&2

echo %UUID% --1>&2

echo %POST% --1>&2

C:\wget_folder\wget ^   
    --header="Content-Type:text/plain" ^   
    --post-data="%POST%" ^   
    --output-document="-" ^   
    --timeout=2 ^     
    http://localhost:9090/job/Test/build/%UUID%/notifyCommit?rev=%REV%    

where Test = name of the job

echo is used to see the value and you can also add exit 2 at the end to know about the issue and whether the post-commit hook script is running or not.

With Chris's inspiring post here:

https://css-tricks.com/different-transitions-for-hover-on-hover-off/

I managed to come up with this:

#banner
{
    display:block;
    width:100%;
    background-repeat:no-repeat;
    background-position:center bottom;
    background-image:url(../images/image1.jpg);
    /* HOVER OFF */
    @include transition(background-image 0.5s ease-in-out); 

    &:hover
    {
        background-image:url(../images/image2.jpg);
        /* HOVER ON */
        @include transition(background-image 0.5s ease-in-out); 
    }
}

I'm guessing this question was mainly about InstallShield given the tags, but in case anyone comes here with the same problem for WiX-based packages (and possibly others), just call the installer with /extract, like so:

C:\> installer.exe /extract

That'll place the MSI in the folder alongside the installer.

Despite all the other great answers none helped me until I found a comment that pointed out this Updating images:

The default pull policy is IfNotPresent which causes the kubelet to skip pulling an image if it already exists.

That's exactly what I wanted, but didn't seem to work.

Reading further said the following:

If you would like to always force a pull, you can do one of the following:

• omit the imagePullPolicy and use :latest as the tag for the image to use.

When I replaced latest with a version (that I had pushed to minikube's Docker daemon), it worked fine.

$ kubectl create deployment presto-coordinator \
    --image=warsaw-data-meetup/presto-coordinator:beta0
deployment.apps/presto-coordinator created

$ kubectl get deployments
NAME                 READY   UP-TO-DATE   AVAILABLE   AGE
presto-coordinator   1/1     1            1           3s

Find the pod of the deployment (using kubectl get pods) and use kubectl describe pod to find out more on the pod.

Set's do not have an order - so you may lose your order when you convert your list into a set, i.e.:

>>> orderedVars = ['0', '1', '2', '3']
>>> setVars = set(orderedVars)
>>> print setVars
('4', '2', '3', '1')

Generally the order will remain, but for large sets it almost certainly won't.

Finally, just incase people are wondering, you don't need a ', ' in the join.

Just: ''.join(set)

:)

Suppose you want to set a pop-up text box for clicking a button lets say bt whose id is button, then code using Toast will somewhat look like this:

Button bt;
bt = (Button) findViewById(R.id.button);
bt.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {            
Toast.makeText(getApplicationContext(),"The text you want to display",Toast.LENGTH_LONG)
}

You could use

var a = document.querySelector('a[data-a="1"]');

instead of

var a = document.querySelector('a[data-a=1]');

Just add weightSum tag to linearlayout to 1 and for the corresponding view beneath it give layout_weight as .9 it will create a space between the views. You can experiment with the values to get appropriate value for you.

It depends which version of the .NET Framework you are using. .NET 4.0 made thread management a whole lot easier using Tasks:

class Program
{
    static void Main(string[] args)
    {
        Task task1 = Task.Factory.StartNew(() => doStuff());
        Task task2 = Task.Factory.StartNew(() => doStuff());
        Task task3 = Task.Factory.StartNew(() => doStuff());

        Task.WaitAll(task1, task2, task3);
                Console.WriteLine("All threads complete");
    }

    static void doStuff()
    {
        //do stuff here
    }
}

In previous versions of .NET you could use the BackgroundWorker object, use ThreadPool.QueueUserWorkItem(), or create your threads manually and use Thread.Join() to wait for them to complete:

static void Main(string[] args)
{
    Thread t1 = new Thread(doStuff);
    t1.Start();

    Thread t2 = new Thread(doStuff);
    t2.Start();

    Thread t3 = new Thread(doStuff);
    t3.Start();

    t1.Join();
    t2.Join();
    t3.Join();

    Console.WriteLine("All threads complete");
}

glob2rx() converts a pattern including a wildcard into the equivalent regular expression. You then need to pass this regular expression onto one of R's pattern matching tools.

If you want to match "blue*" where * has the usual wildcard, not regular expression, meaning we use glob2rx() to convert the wildcard pattern into a useful regular expression:

> glob2rx("blue*")
[1] "^blue"

The returned object is a regular expression.

Given your data:

x <- c('red','blue1','blue2', 'red2')

we can pattern match using grep() or similar tools:

> grx <- glob2rx("blue*")
> grep(grx, x)
[1] 2 3
> grep(grx, x, value = TRUE)
[1] "blue1" "blue2"
> grepl(grx, x)
[1] FALSE  TRUE  TRUE FALSE

As for the selecting rows problem you posted

> a <- data.frame(x =  c('red','blue1','blue2', 'red2'))
> with(a, a[grepl(grx, x), ])
[1] blue1 blue2
Levels: blue1 blue2 red red2
> with(a, a[grep(grx, x), ])
[1] blue1 blue2
Levels: blue1 blue2 red red2

or via subset():

> with(a, subset(a, subset = grepl(grx, x)))
      x
2 blue1
3 blue2

Hope that explains what grob2rx() does and how to use it?

It's just what it says:

You have specified encoding as a keyword argument, but "r" as a positional argument. You can't have positional arguments after keyword arguments. Perhaps you wanted to do:

inputFile = open((x), "r", encoding = "utf8")

To convert a DateTime to a TimeSpan you should choose a base date/time - e.g. midnight of January 1st, 2000, and subtract it from your DateTime value (and add it when you want to convert back to DateTime).

If you simply want to convert a DateTime to a number you can use the Ticks property.

While the accepted answer is very true, just want to point out that AllowTransparency has some downfalls. It does not allow child window controls to show up, ie WebBrowser, and it usually forces software rendering which can have negative performance effects.

There is a better work around though.

When you want to create a window with no border that is resizeable and is able to host a WebBrowser control or a Frame control pointed to a URL you simply couldn't, the contents of said control would show empty.

I found a workaround though; in the Window, if you set the WindowStyle to None, ResizeMode to NoResize (bear with me, you will still be able to resize once done) then make sure you have UNCHECKED AllowsTransparency you will have a static sized window with no border and will show the browser control.

Now, you probably still want to be able to resize right? Well we can to that with a interop call:

    [DllImport("user32.dll", CharSet = CharSet.Auto)]
    private static extern IntPtr SendMessage(IntPtr hWnd, uint Msg, IntPtr wParam, IntPtr lParam);

    [DllImportAttribute("user32.dll")]
    public static extern bool ReleaseCapture();

    //Attach this to the MouseDown event of your drag control to move the window in place of the title bar
    private void WindowDrag(object sender, MouseButtonEventArgs e) // MouseDown
    {
        ReleaseCapture();
        SendMessage(new WindowInteropHelper(this).Handle,
            0xA1, (IntPtr)0x2, (IntPtr)0);
    }

    //Attach this to the PreviewMousLeftButtonDown event of the grip control in the lower right corner of the form to resize the window
    private void WindowResize(object sender, MouseButtonEventArgs e) //PreviewMousLeftButtonDown
    {
        HwndSource hwndSource = PresentationSource.FromVisual((Visual)sender) as HwndSource;
        SendMessage(hwndSource.Handle, 0x112, (IntPtr)61448, IntPtr.Zero);
    }

And voila, A WPF window with no border and still movable and resizable without losing compatibility with with controls like WebBrowser

Original answer using git's start-ssh-agent

Make sure you have Git installed and have git's cmd folder in your PATH. For example, on my computer the path to git's cmd folder is C:\Program Files\Git\cmd

Make sure your id_rsa file is in the folder c:\users\yourusername\.ssh

Restart your command prompt if you haven't already, and then run start-ssh-agent. It will find your id_rsa and prompt you for the passphrase

Update 2019 - A better solution if you're using Windows 10: OpenSSH is available as part of Windows 10 which makes using SSH from cmd/powershell much easier in my opinion. It also doesn't rely on having git installed, unlike my previous solution.

1. Open Manage optional features from the start menu and make sure you have Open SSH Client in the list. If not, you should be able to add it.

2. Open Services from the start Menu

3. Scroll down to OpenSSH Authentication Agent > right click > properties

4. Change the Startup type from Disabled to any of the other 3 options. I have mine set to Automatic (Delayed Start)

5. Open cmd and type where ssh to confirm that the top listed path is in System32. Mine is installed at C:\Windows\System32\OpenSSH\ssh.exe. If it's not in the list you may need to close and reopen cmd.

Once you've followed these steps, ssh-agent, ssh-add and all other ssh commands should now work from cmd. To start the agent you can simply type ssh-agent.

6. Optional step/troubleshooting: If you use git, you should set the GIT_SSH environment variable to the output of where ssh which you ran before (e.g C:\Windows\System32\OpenSSH\ssh.exe). This is to stop inconsistencies between the version of ssh you're using (and your keys are added/generated with) and the version that git uses internally. This should prevent issues that are similar to this

Some nice things about this solution:

• You won't need to start the ssh-agent every time you restart your computer
• Identities that you've added (using ssh-add) will get automatically added after restarts. (It works for me, but you might possibly need a config file in your c:\Users\User\.ssh folder)
• You don't need git!
• You can register any rsa private key to the agent. The other solution will only pick up a key named id_rsa

Hope this helps

I haven't been using jquery for a while but you might be looking for this:

jQuery.makeArray(obj)

I agree with the first answer but I would also declare the class as final so that it cannot be extended as extending a singleton violates the singleton pattern. Also the instance variable should be private so that it cannot be accessed directly. Also make the __clone method private so that you cannot clone the singleton object.

Below is some example code.

/**
 * Singleton class
 *
 */
final class UserFactory
{
    private static $_instance = null;

    /**
     * Private constructor
     *
     */
    private function __construct() {}

    /**
     * Private clone method
     *
     */
     private function __clone() {}

    /**
     * Call this method to get singleton
     *
     * @return UserFactory
     */
    public static function getInstance()
    {
        if (self::$_instance === null) {
            self::$_instance = new UserFactory();
        }
        return self::$_instance;
    }
}

Example Usage

$user_factory = UserFactory::getInstance();

What this stops you from doing (which would violate the singleton pattern..

YOU CANNOT DO THIS!

$user_factory = UserFactory::$_instance;

class SecondUserFactory extends UserFactory { }

instead of going through this you can always use another approach which is also fast

create a new partial view in the Shared Directory and call your partial view in your layout as

@Html.Partial("MyPartialView")

in your partial view you can call your db and perform what ever you want to do

@{
    IEnumerable<HOXAT.Models.CourseCategory> categories = new HOXAT.Models.HOXATEntities().CourseCategories;
}

<div>
//do what ever here
</div>

assuming you have added your Entity Framework Database

I fought with this one for a while. My goal was to have a table with headers where the widths of the each header column was the the same as the corresponding body column and was the minimum size necessary to fit the data. also the body data was scrollable underneath header.

I solved this by using divs and not tables. Each "table" was a div with the header being a div of divs and the body being a div of divs. I used the style as indicated by @sushil above. I added a bit of javascript/jQuery to balance the columns. Maybe 20-30 lines.

Unfortunately I lost the code and have to rebuild it. I know this is a bit old, but maybe it will help someone else.

Unfortunately none of the above solved the problem for me.

I didn't want to edit the bootstrap-responsive.css so I went the easy way:

1. Create a css with priority over bootstrap-responsive.css
2. Copy all the content of the @media (min-width: 768px) and (max-width: 979px) (line 461 with latest bootstrap version 2.3.1 as of today)
3. Paste it in your high priority css
4. In your css, put @media (min-width: 979px) in the place where it said @media (min-width: 768px) and (max-width: 979px) before. This sets the from 768 to 979 style to everything above 768.

That's it. It's not optimal, you will have duplicated css, but it works 100% perfect!

change it to Console (/SUBSYSTEM:CONSOLE) it will work

With below converter

public class CustomDateTimeConverter : IsoDateTimeConverter
    {
        public CustomDateTimeConverter()
        {
            DateTimeFormat = "yyyy-MM-dd";
        }

        public CustomDateTimeConverter(string format)
        {
            DateTimeFormat = format;
        }
    }

Can use it with a default custom format

class ReturnObjectA 
{
    [JsonConverter(typeof(DateFormatConverter))]
    public DateTime ReturnDate { get;set;}
}

Or any specified format for a property

class ReturnObjectB 
{
    [JsonConverter(typeof(DateFormatConverter), "dd MMM yy")]
    public DateTime ReturnDate { get;set;}
}

I got this exception because I typed:

ws.get_Range("K:K").EntireColumn.AutoFit();
ws.get_Range("N:N").EntireColumn.AutoFit();
ws.get_Range("0:0").EntireColumn.AutoFit();

See a mistake? Hint: Excel is accepting indexing from 1, but not from 0 as C# does.

    $routeProvider
 .when('/main' , {templateUrl: 'partials/main.html',  controller: MainController})
 .when('/login', {templateUrl: 'partials/login.html', controller: LoginController}).
 .when('/login', {templateUrl: 'partials/index.html', controller: IndexController})
 .otherwise({redirectTo: '/index'});

You could use table, i.e.

n_occur <- data.frame(table(vocabulary$id))

gives you a data frame with a list of ids and the number of times they occurred.

n_occur[n_occur$Freq > 1,]

tells you which ids occurred more than once.

vocabulary[vocabulary$id %in% n_occur$Var1[n_occur$Freq > 1],]

returns the records with more than one occurrence.

Assuming you also want to strip whitespace at beginning and end of each line, you can map the string strip function to the list returned by readlines:

map(str.strip, open('filename').readlines())

There is actually a property for this in the CSS4 media query draft.

The ‘pointer’ media feature is used to query about the presence and accuracy of a pointing device such as a mouse. If a device has multiple input mechanisms, it is recommended that the UA reports the characteristics of the least capable pointing device of the primary input mechanisms. This media query takes the following values:

‘none’
- The input mechanism of the device does not include a pointing device.

‘coarse’
- The input mechanism of the device includes a pointing device of limited accuracy.

‘fine’
- The input mechanism of the device includes an accurate pointing device.

This would be used as such:

/* Make radio buttons and check boxes larger if we have an inaccurate pointing device */
@media (pointer:coarse) {
    input[type="checkbox"], input[type="radio"] {
        min-width:30px;
        min-height:40px;
        background:transparent;
    }
}

I also found a ticket in the Chromium project related to this.

Browser compatibility can be tested at Quirksmode. These are my results (22 jan 2013):

• Chrome/Win: Works
• Chrome/iOS: Doesn't work
• Safari/iOS6: Doesn't work

Try this:

$Date = $row['valdate']->format('d/m/Y'); // the result will 01/12/2015

NOTE: $row['valdate'] its a value date in the database

One way of doing this without changing Volley's source code is to check for the response data in the VolleyError and parse it your self.

As of f605da3 commit, Volley throws a ServerError exception that contains the raw network response.

So you can do something similar to this in your error listener:

/* import com.android.volley.toolbox.HttpHeaderParser; */
public void onErrorResponse(VolleyError error) {

    // As of f605da3 the following should work
    NetworkResponse response = error.networkResponse;
    if (error instanceof ServerError && response != null) {
        try {
            String res = new String(response.data,
                       HttpHeaderParser.parseCharset(response.headers, "utf-8"));
            // Now you can use any deserializer to make sense of data
            JSONObject obj = new JSONObject(res);
        } catch (UnsupportedEncodingException e1) {
            // Couldn't properly decode data to string
            e1.printStackTrace();
        } catch (JSONException e2) {
            // returned data is not JSONObject?
            e2.printStackTrace();
        }
    }
}

For future, if Volley changes, one can follow the above approach where you need to check the VolleyError for raw data that has been sent by the server and parse it.

I hope that they implement that TODO mentioned in the source file.

Use:

document.getElementById("resultFrame").contentWindow.Reset();

to access the Reset function in the iframe

document.getElementById("resultFrame") will get the iframe in your code, and contentWindow will get the window object in the iframe. Once you have the child window, you can refer to javascript in that context.

Also see HERE in particular the answer from bobince.

Since Android Studio V1.0 the jar file is available inside the following project link:

debug ver: "your_app"\build\intermediates\bundles\debug\classes.jar

release ver: "your_app"\build\intermediates\bundles\release\classes.jar

The JAR file is created on the build procedure, In Android Studio GUI it's from Build->Make Project and from CMD line it's "gradlew build".

Django has method_decorator which is a decorator that turns any decorator into a method decorator, you can see how it's implemented in django.utils.decorators:

https://github.com/django/django/blob/50cf183d219face91822c75fa0a15fe2fe3cb32d/django/utils/decorators.py#L53

https://docs.djangoproject.com/en/3.0/topics/class-based-views/intro/#decorating-the-class

Just come across this, the answer is simple, use ISNULL. SQL won't return rows if the field you are testing has no value (in some of the records) when doing a text comparison search, eg:

WHERE wpp.comment NOT LIKE '%CORE%'

So, you have temporarily substitute a value in the null (empty) records by using the ISNULL command, eg

WHERE (ISNULL(wpp.comment,'')) NOT LIKE '%CORE%'

This will then show all your records that have nulls and omit any that have your matching criteria. If you wanted, you could put something in the commas to help you remember, eg

WHERE (ISNULL(wpp.comment,'some_records_have_no_value')) NOT LIKE '%CORE%'

1. check the rsp's reply
2. check that you have permissions to read the file
3. check whether the file is not locked by other application. It is relevant mostly if you are on windows. for example I think that you can get the exception if you are trying to read the file while it is opened in notepad

Here is the answer: Download the "Windows Mobile Device Center" for your machine type, likely 64bit.
http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=3182

Before you run the install, change the compatibility settings to 'Windows 7'. Then install it... Then run it: You'll find it under 'WMDC'.. Your device should now recognize, when plugged in, mine did!

I was trying to fetch table meta data, but had the following error:

Using:

String JDBC_URL = "jdbc:h2:mem:test;DB_CLOSE_DELAY=-1";

DatabaseMetaData metaData = connection.getMetaData();
...
metaData.getColumns(...);

returned an empty ResultSet.

But using the following URL instead it worked properly:

String JDBC_URL = "jdbc:h2:mem:test;DB_CLOSE_DELAY=-1;DATABASE_TO_UPPER=false";

There was a need to specify: DATABASE_TO_UPPER=false

You can use git stash to save the current repository before doing the commit you want to make (after merging the changes from the upstream repo with git stash pop). I had to do this yesterday when I had the same problem.

it means "append "THIS" to the current value"

example:

a = "hello"; a += " world";

printing a now will output: "hello world"

In JdbcTemplate , queryForInt, queryForLong, queryForObject all such methods expects that executed query will return one and only one row. If you get no rows or more than one row that will result in IncorrectResultSizeDataAccessException . Now the correct way is not to catch this exception or EmptyResultDataAccessException, but make sure the query you are using should return only one row. If at all it is not possible then use query method instead.

List<String> strLst  = getJdbcTemplate().query(sql,new RowMapper {

  public Object mapRow(ResultSet rs, int rowNum) throws SQLException {
        return rs.getString(1);
  }

});

if ( strLst.isEmpty() ){
  return null;
}else if ( strLst.size() == 1 ) { // list contains exactly 1 element
  return strLst.get(0);
}else{  // list contains more than 1 elements
  //your wish, you can either throw the exception or return 1st element.    
}

Many of the answerers spotted the issue and already gave the solution.

I just want to suggest another solution, which is changing the Glogal variable value from within the tool Mysql Workbench. That is ofcourse IF you use Workbench running locally on server (or via SSH connection)

You just connect to your instance and go on menu:

Server -> Options File -> Networking -> max_allowed_packed

You set the desired value and then you need to restart MySql Service.

copy your Json and paste at textbox on http://json2csharp.com/ and click on Generate button,

A cs class will be generated use that cs file as below:

var generatedcsResponce = JsonConvert.DeserializeObject(yourJson);

where RootObject is the name of the generated cs file;

Set a flag on hover:

var over = false;
$('#elem').hover(function() {
  over = true;
},
function () {
  over = false;
});

Then just check your flag.

This might be trivial and not related to the OP's question, but I often made this mistaken at the beginning when I was learning scripting

VAR_NAME = $(hostname)
echo "the hostname is ${VAR_NAME}"  

This will produce 'command not found' response. The correct way is to eliminate the spaces

VAR_NAME=$(hostname)

The following code allows you to specify the row/column number and get the resulting cell value:

WebDriver driver = new ChromeDriver();
WebElement base = driver.findElement(By.className("Table"));
tableRows = base.findElements(By.tagName("tr"));
List<WebElement> tableCols = tableRows.get([ROW_NUM]).findElements(By.tagName("td"));
String cellValue = tableCols.get([COL_NUM]).getText();

I have solved it by discarding my local amended commit and adding the new changes on top:

# Rewind to commit before conflicting
git reset --soft HEAD~1

# Pull the remote version
git pull

# Add the new commit on top
git add ...
git commit
git push

Import JSON/CSV file in MongoDB

• wait wait
• first check mongoimport.exe file in your bin folder(C:\Program Files\MongoDB\Server\4.4\bin) if it is not then download mongodb database tools(https://www.mongodb.com/try/download/database-tools)
• copy extracted(unzip) files(inside unzipped bin) to bin folder(C:\Program Files\MongoDB\Server\4.4\bin)
• copy your json file to bin folder(C:\Program Files\MongoDB\Server\4.4\bin)
• Now open your commond prompt change its directory to bin

cd "C:\Program Files\MongoDB\Server\4.4\bin"

• Now copy this on your commnad prompt

mongoimport -d tymongo -c test --type json --file restaurants.json

• where d- database(tymongo-database name), c-collection(test-collection name)

FOR CSV FILE

 mongoimport -d tymongo -c test --type csv --file database2.csv --headerline

You need to tell the run to wait until the process is finished. Something like:

const DontWaitUntilFinished = false, ShowWindow = 1, DontShowWindow = 0, WaitUntilFinished = true
set oShell = WScript.CreateObject("WScript.Shell")
command = "cmd /c C:\windows\system32\wscript.exe <path>\myScript.vbs " & args
oShell.Run command, DontShowWindow, WaitUntilFinished

In the script itself, start Excel like so. While debugging start visible:

File = "c:\test\myfile.xls"
oShell.run """C:\Program Files\Microsoft Office\Office14\EXCEL.EXE"" " & File, 1, true

In python, extracting substring form string can be done using findall method in regular expression (re) module.

>>> import re
>>> s = 'gfgfdAAA1234ZZZuijjk'
>>> ss = re.findall('AAA(.+)ZZZ', s)
>>> print ss
['1234']

I also face this issue but it is resolved in different way. Steps that I follow may be helpful for others.

1. Right click on project (the one you are working on)
2. Go to Properties > Java Build Path > JRE System Library
3. Click Edit... on the right
4. Choose the JRE 7

You can use the row_numer() over(partition by ...) syntax like so:

select * from
(
select *
, ROW_NUMBER() OVER(PARTITION BY CName ORDER BY AddressLine) AS row
from myTable
) as a
where row = 1

What this does is that it creates a column called row, which is a counter that increments every time it sees the same CName, and indexes those occurrences by AddressLine. By imposing where row = 1, one can select the CName whose AddressLine comes first alphabetically. If the order by was desc, then it would pick the CName whose AddressLine comes last alphabetically.

That's strange, it definitely works for me:

from matplotlib import pyplot as plt

plt.figure(figsize = (20,2))
plt.imshow(random.rand(8, 90), interpolation='nearest')

I am using the "MacOSX" backend, btw.

Date.strptime(updated,"%a, %d %m %Y %H:%M:%S %Z")

Should be:

Date.strptime(updated, '%a, %d %b %Y %H:%M:%S %Z')

strtotime(), as in date("F j, Y", strtotime("yesterday"));

Use c_str() to convert the std::string to const char *.

cout << "String is  : " << text.c_str() << endl ;

I'm not sure it's worth it for me to type this all up from scratch since this article published in A List Apart does a pretty good job explaining it. MDN also has a handy guide for HTML5 forms and validation (covering the API and also the related CSS).

We can use RegularExpressionValidator to validate email address format. You need to specify the regular expression in ValidationExpression property of RegularExpressionValidator. So it will look like

 <asp:RegularExpressionValidator ID="validateEmail"    
  runat="server" ErrorMessage="Invalid email."
  ControlToValidate="txtEmail" 
  ValidationExpression="^([\w\.\-]+)@([\w\-]+)((\.(\w){2,3})+)$" />

Also in event handler of button or link you need to check !Page.IsValid. Check sample code here : sample code

Also if you don't want to use RegularExpressionValidator you can write simple validate method and in that method usinf RegEx class of System.Text.RegularExpressions namespace.

Check example:

example

egrep -o '^[^:]*:'

You can use mkdir:

$ man 2 mkdir

#include <sys/stat.h>
#include <sys/types.h>

int result = mkdir("/home/me/test.txt", 0777);

I can't see it listed here, but I encountered the problem of my R.java being removed and not being automatic rebuilt.

This happened to me when I was dealing with switch statements and strings. Eclipse suggested that I change my projects compliance to 1.7 which promptly broke the project (R.java) as Android can't use this compliance.

Console:

[2013-03-12 17:26:33 - CrimeAtlas] Android requires compiler compliance level 5.0 or 6.0. Found '1.7' instead. Please use Android Tools > Fix Project Properties.

I fixed the error by using "Fix Project Properties" and then going through the log like suggested. I commented out the XML in files mentioned replacing them temporarily with a LinearLayout. When it's fixed, bam, it reappears (if "Build Automaticly" is on). I can then change the XML files back if there was nothing wrong.

A couple ideas were tossed around using "typeof", jQuery ".is" and ".filter" so I thought I would post up a quick perf compare of them. The typeof appears to be the best choice for this. While the others will work, there appears to be a clear performance difference when invoking the jq library for this effort.

LINQ to SQL only supports 1 to 1 mapping of database tables, views, sprocs and functions available in Microsoft SQL Server. It's a great API to use for quick data access construction to relatively well designed SQL Server databases. LINQ2SQL was first released with C# 3.0 and .Net Framework 3.5.

LINQ to Entities (ADO.Net Entity Framework) is an ORM (Object Relational Mapper) API which allows for a broad definition of object domain models and their relationships to many different ADO.Net data providers. As such, you can mix and match a number of different database vendors, application servers or protocols to design an aggregated mash-up of objects which are constructed from a variety of tables, sources, services, etc. ADO.Net Framework was released with the .Net Framework 3.5 SP1.

This is a good introductory article on MSDN: Introducing LINQ to Relational Data

I don't have enough rep to comment in the correct place, but I spent all day on this so want to share.

While trying to implement the "MultipleButtonAttribute" solution ValueProvider.GetValue(keyValue) would incorrectly come back null.

It turned out I was referencing System.Web.MVC version 3.0 when it should have been 4.0 (other assemblies are 4.0). I don't know why my project didn't upgrade correctly and I had no other obvious problems.

So if your ActionNameSelectorAttribute is not working... check that.

In the summary() output, the function also counts the NAs so one can use this function if one wants the sum of NAs in several variables.

The ODP.Net provider from oracle uses bind by position as default. To change the behavior to bind by name. Set property BindByName to true. Than you can dismiss the double definition of parameters.

using(OracleCommand cmd = con.CreateCommand()) {
    ...
    cmd.BindByName = true;
    ...
}

Maybe you can try something like this:

Using a directive

directive('watchChange', function() {
    return {
        scope: {
            onchange: '&watchChange'
        },
        link: function(scope, element, attrs) {
            element.on('input', function() {
                scope.onchange();
            });
        }
    };
});

Test with [char]9, such as:

$Tab = [char]9
Write-Output "$Tab hello"

Output:

     hello

Setting the following option:

The way I got around this issue is by not calling intent within a dialog. **** use syntax applicable to activity or fragment accordingly

@Override
public void onClick(DialogInterface dialog, int which) {
    checkvariable= true;
    getActivity().finish();
}

@Override
public void onStop() {
    super.onStop();
    if (checkvariable) {
        startActivity(intent); 
    }
}

If you have a _Layout.cshtml view like this

<html>
    <body>
        @RenderBody()
        @RenderSection("scripts", required: false)
    </body>
</html>

then you can have an index.cshtml content view like this

@section scripts {
     <script type="text/javascript">alert('hello');</script>
}

the required indicates whether or not the view using the layout page must have a scripts section

also you should click right button on mouse at your projectname and choose "open module settings" or press F4 button. Then on "dependencies" tab add your lib.jar to declare needed lib

Ok, instead of identifying players by name track with sockets through which they have connected. You can have a implementation like

Server

var allClients = [];
io.sockets.on('connection', function(socket) {
   allClients.push(socket);

   socket.on('disconnect', function() {
      console.log('Got disconnect!');

      var i = allClients.indexOf(socket);
      allClients.splice(i, 1);
   });
});

Hope this will help you to think in another way
