You can always loop using an index counter the conventional C style looping:

for i in range(len(l)-1):
    print l[i+1]

It is always better to follow the "loop on every element" style because that's the normal thing to do, but if it gets in your way, just remember the conventional style is also supported, always.

Damir is correct,

Your subquery needs to ensure that dps_user.id equals um.profile_id, otherwise it will grab the top row which might, but probably not equal your id of 'u162231993'

Your query should look like this:

SELECT u.id, mbg.marker_value 
FROM dps_user u
LEFT JOIN 
    (SELECT TOP 1 m.marker_value, um.profile_id
     FROM dps_usr_markers um (NOLOCK)
         INNER JOIN dps_markers m (NOLOCK) 
             ON m.marker_id= um.marker_id AND 
                m.marker_key = 'moneyBackGuaranteeLength'
     WHERE u.id = um.profile_id
     ORDER BY m.creation_date
    ) MBG ON MBG.profile_id=u.id 
WHERE u.id = 'u162231993'

i had the same problem and i search and search .. but got no result.
so i put my brain in over drive. and i came up with the below solution. try this in the View Page

at the head of the page add this code

 @{
      var Lst = ViewBag.data as IEnumerable<MyProject.Models.Person>;
    }

to display the particular attribute use the below code

@Lst.FirstOrDefault().FirstName

in your case use below code.

<td>@Lst.FirstOrDefault().FirstName </td>  

Hope this helps...

Came across this issue two days back, spent whole complete two days, So I found that I need to give the access to IUSR user group at DCOMCNFG --> My Computer Properties --> Com Security --> Launch and Activation Permissions --> Edit defaults and give all rights to IUSR.

hope it will help someone....

This problem is solved easily with moment.js, like this example:

var difference = mostDate.diff(minorDate, "minutes");

The second parameter can be changed for another parameters, see the moment.js documentation.

e.g.: "days", "hours", "minutes", etc.

http://momentjs.com/docs/

The CDN for moment.js is available here:

https://cdnjs.com/libraries/moment.js

Thanks.

EDIT:

mostDate and minorDate should be a moment type.

EDIT 2:

For those who are reading my answer in 2020+, momentjs is now a legacy project.

If you are still looking for a well-known library to do this job, I would recommend date-fns.

// How many minutes are between 2 July 2014 12:07:59 and 2 July 2014 12:20:00?
var result = differenceInMinutes(
  new Date(2014, 6, 2, 12, 20, 0),
  new Date(2014, 6, 2, 12, 7, 59)
)
//=> 12

View -> Show Symbol -> uncheck Show End of Line.

You can have as many classes as you wish like this

public class Fun {
    Fun() {
        System.out.println("Fun constructor");
    }
    void fun() {
        System.out.println("Fun mathod");
    }
    public static void main(String[] args) {
        Fun fu = new Fun();
        fu.fun();
        Fen fe = new Fen();
        fe.fen();
        Fin fi = new Fin();
        fi.fin();
        Fon fo = new Fon();
        fo.fon();
        Fan fa = new Fan();
        fa.fan();
        fa.run();
    }
}

class Fen {
    Fen() {
        System.out.println("fen construuctor");

    }
    void fen() {
        System.out.println("Fen method");
    }
}

class Fin {
    void fin() {
        System.out.println("Fin method");
    }
}

class Fon {
    void fon() {
        System.out.println("Fon method");
    } 
}

class Fan {
    void fan() {
        System.out.println("Fan method");
    }
    public void run() {
        System.out.println("run");
    }
}

I was using CakePHP and I was seeing this error:

This page isn’t working
localhost is currently unable to handle this request.
HTTP ERROR 500

I went to see the CakePHP Debug Level defined at app\config\core.php:

/**
 * CakePHP Debug Level:
 *
 * Production Mode:
 *  0: No error messages, errors, or warnings shown. Flash messages redirect.
 *
 * Development Mode:
 *  1: Errors and warnings shown, model caches refreshed, flash messages halted.
 *  2: As in 1, but also with full debug messages and SQL output.
 *  3: As in 2, but also with full controller dump.
 *
 * In production mode, flash messages redirect after a time interval.
 * In development mode, you need to click the flash message to continue.
 */
Configure::write('debug', 0);

I chanted the value from 0 to 1:

Configure::write('debug', 1);

After this change, when trying to reload the page again, I saw the corresponding error:

Fatal error: Uncaught Exception: Facebook needs the CURL PHP extension.

Conclusion: The solution in my case to see the errors was to change the CakePHP Debug Level from 0 to 1 in order to show errors and warnings.

1) Update Devise so that it can handle Rails 4.0 by adding this line to your application's Gemfile:

gem 'devise', '3.0.0.rc' 

Then execute:

$ bundle

2) Add the old functionality of attr_accessible again to rails 4.0

Try to use attr_accessible and don't comment this out.

Add this line to your application's Gemfile:

gem 'protected_attributes'

Then execute:

$ bundle

You can do it in one line by converting your lists to sets and using set.difference:

item_list = ['item', 5, 'foo', 3.14, True]
list_to_remove = ['item', 5, 'foo']

final_list = list(set(item_list) - set(list_to_remove))

Would give you the following output:

final_list = [3.14, True]

Note: this will remove duplicates in your input list and the elements in the output can be in any order (because sets don't preserve order). It also requires all elements in both of your lists to be hashable.

I needed to correct the privileges.REVOKE ALL PRIVILEGES ONlogs.* FROM 'root'@'root'; GRANT ALL PRIVILEGES ONlogs.* TO 'root'@'root'WITH GRANT OPTION;

OK, this error may seem obvious, but one day I was looking for an answer JUST TO FOUND OUT THAT I HAD 2 times COMPONENTS declared. it was driving me nuts as VueJS does not complain at all when you declare it 2 times, obvious I had a lot of code in between, and when I added a new component, I placed the declaration in the top, while I also had one close to the bottom. So next time looks for this first, saves a lot of time

Python 3.3 introduces Python Launcher for Windows that is installed into c:\Windows\ as py.exe and pyw.exe by the installer. The installer also creates associations with .py and .pyw. Then add #!python3 or #!python2 as the first lline. No need to add anything to the PATH environment variable.

Update: Just install Python 3.3 from the official python.org/download. It will add also the launcher. Then add the first line to your script that has the .py extension. Then you can launch the script by simply typing the scriptname.py on the cmd line, od more explicitly by py scriptname.py, and also by double clicking on the scipt icon.

The py.exe looks for C:\PythonXX\python.exe where XX is related to the installed versions of Python at the computer. Say, you have Python 2.7.6 installed into C:\Python27, and Python 3.3.3 installed into C:\Python33. The first line in the script will be used by the Python launcher to choose one of the installed versions. The default (i.e. without telling the version explicitly) is to use the highest version of Python 2 that is available on the computer.

Remember, no quotes, no matter if your path has spaces (as opposed to command line execution).

See here: Find the JRE for Eclipse

 $table  = 'your table name';
 $column = 'q6'
 $add = mysql_query("ALTER TABLE $table ADD $column VARCHAR( 255 ) NOT NULL");

you can change VARCHAR( 255 ) NOT NULL into what ever datatype you want.

Adding the following on the div surrounding the element in question fixed this for me.

-webkit-transform-style: preserve-3d;

The jagged edges were appearing around the video window in my case.

A quick search of the docs for the ListView class has turned up getChildCount() and getChildAt() methods inherited from ViewGroup. Can you iterate through them using these? I'm not sure but it's worth a try.

I found that the repo that had the package was not enabled. On OEL7,

$ vi /etc/yum.repos.d/ULN-Base.repo
Set enabled to 1 for ol7_optional_latest

$ yum install php-bcmath

and that worked...

I used the following command to find where the package was

$ yum --noplugins --showduplicates --enablerepo \* --disablerepo \*-source --disablerepo C5.\*,c5-media,\*debug\*,\*-source list \*bcmath

Make a script like this:

#!/bin/bash

echo $((0x$1)).$((0x$2)).$((0x$3)).$((0x$4))

Example:

sh converthextoip.sh c0 a8 00 0b

Result:

192.168.0.11

For anyone looking to use variable with the match method, this worked for me

var alpha = 'fig';
'food fight'.match(alpha + 'ht')[0]; // fight

I think what you want to do is

<link rel="stylesheet" type="text/css" href="font/font-face/my-font-face.css">

The basic difference is, like you stated, generating GUI events from the BackgroundWorker. If the thread does not need to update the display or generate events for the main GUI thread, then it can be a simple thread.

Functional Component

Actually, for functional component the best practice is like below, I create a sample Spinner component:

import React from 'react';
import { ActivityIndicator } from 'react-native';
import { colors } from 'helpers/theme';
import type { FC } from 'types';

interface SpinnerProps {
  color?: string;
  size?: 'small' | 'large' | 1 | 0;
  animating?: boolean;
  hidesWhenStopped?: boolean;
}

const Spinner: FC<SpinnerProps> = ({
  color,
  size,
  animating,
  hidesWhenStopped,
}) => (
  <ActivityIndicator
    color={color}
    size={size}
    animating={animating}
    hidesWhenStopped={hidesWhenStopped}
  />
);

Spinner.defaultProps = {
  animating: true,
  color: colors.primary,
  hidesWhenStopped: true,
  size: 'small',
};

export default Spinner;

If your data resides on HDFS, perhaps the fastest approach is to use hadoop streaming. Apache Pig's COUNT UDF, operates on a bag, and therefore uses a single reducer to compute the number of rows. Instead you can manually set the number of reducers in a simple hadoop streaming script as follows:

$HADOOP_HOME/bin/hadoop jar $HADOOP_HOME/hadoop-streaming.jar -Dmapred.reduce.tasks=100 -input <input_path> -output <output_path> -mapper /bin/cat -reducer "wc -l"

Note that I manually set the number of reducers to 100, but you can tune this parameter. Once the map-reduce job is done, the result from each reducer is stored in a separate file. The final count of rows is the sum of numbers returned by all reducers. you can get the final count of rows as follows:

$HADOOP_HOME/bin/hadoop fs -cat <output_path>/* | paste -sd+ | bc

With shortcuts available, the quickest way is to

1. Open the Developer Tools

   • Windows: F12 or Ctrl+Shift+I
   • Mac: Cmd+Opt+I

2. Open the Command Menu

   • Windows: Ctrl+Shift+P
   • Mac: Cmd+Shift+P

3. Type print and select Emulate CSS print media type from the context menu

   

Looking at the excellent and currently most-upvoted answer by lmeurs, I think this solution might also remain stable over time.

var dict = File.ReadLines("test.txt")
               .Where(line => !string.IsNullOrWhitespace(line))
               .Select(line => line.Split(new char[] { '=' }, 2, 0))
               .ToDictionary(parts => parts[0], parts => parts[1]);


or 

    enter code here

If you're using Windows 10 with the built-in SSH, as of August 2020 it only supports ed25519 keys. You'll get the key_load_public: invalid format error if you use e.g. an RSA key.

As per this GitHub issue it should be fixed via Windows Update some time in 2020. So one solution is to just wait for the update to ship.

If you can't wait, a workaround is to generate a new ed25519 key, which is good advice anyway.

> ssh-keygen -o -a 100 -t ed25519

You can use it with e.g. github, but some older systems might not support this newer format.

After generating your key, if you're using either of the below features, don't forget to update them!

1. ~\.ssh\config might still point to the old key.
2. Add the new key to ssh-agent via the ssh-add command

Boost.Config offers these typedefs for toolsets that do not provide them natively. The documentation for this specific functionality is here: Standard Integer Types

Perhaps you have the compiler settings for your IDE set to Java 1.4 mode even if you are using a Java 5 JDK? Otherwise I agree with the other people who already mentioned autoboxing/unboxing.

I have found the solution to this issue using ObjectDoesNotExist on this way

After this, my code works as I need

Thanks any way, your post help me to solve my issue

The problem here is that you have two different languages that solve two different problems... its like comparing C++ with assembler.

Python is for rapid application development and for when performance is a minimal concern.

C++ is not for rapid application development and inherits a legacy of speed from C - for low level programming.

1. Edit the file /etc/postgresql/<version>/main/pg_hba.conf and find the following line:

   local   all             postgres                                md5
   

2. Edit the line and change md5 at the end to trust and save the file

3. Reload the postgresql service

   $ sudo service postgresql reload
   

4. This will load the configuration files. Now you can modify the postgres user by logging into the psql shell

   $ psql -U postgres
   

5. Update the postgres user's password

   alter user postgres with password 'secure-passwd-here';
   

6. Edit the file /etc/postgresql/<version>/main/pg_hba.conf and change trust back to md5 and save the file

7. Reload the postgresql service

   $ sudo service postgresql reload
   

8. Verify that the password change is working

   $ psql -U postgres -W
   

There is an interesting Video on YouTube about this. Its from Linus Torwalds himself: Goolge Tech Talk: Linus Torvalds on git

It is simple actually, like C programming you just need to pass the array indices on the right hand side while declaration. But yeah the syntax will be like [0:3] for 4 elements.

reg a[0:3]; 

This will create a 1D of array of single bit. Similarly 2D array can be created like this:

reg [0:3][0:2];

Now in C suppose you create a 2D array of int, then it will internally create a 2D array of 32 bits. But unfortunately Verilog is an HDL, so it thinks in bits rather then bunch of bits (though int datatype is there in Verilog), it can allow you to create any number of bits to be stored inside an element of array (which is not the case with C, you can't store 5-bits in every element of 2D array in C). So to create a 2D array, in which every individual element can hold 5 bit value, you should write this:

reg [0:4] a [0:3][0:2];

Ok so I was able to figure out for the version 5.2. You will first need to create assets folder in your public folder then put css folder and all css files into it then link it like this :

<link href="assets/css/bootstrap.min.css" rel="stylesheet">

Hope that helps!

Try something like:

$post_data="dispnumber=567567567&extension=6";
$url="http://xxxxxxxx.xxx/xx/xx";

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/x-www-form-urlencoded'));   
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
$result = curl_exec($ch);

echo $result;

Best way to find the average of some numbers is trying Classes ......

public static void main(String[] args) {
    average(1,2,5,4);

}

public static void average(int...numbers){
    int total = 0;
    for(int x: numbers){
        total+=x;
    }
    System.out.println("Average is: "+(double)total/numbers.length);

}

If you are getting this error in Workbench but you are able to log in from terminal then follow this steps.

First simply log in with your current password:

sudo mysql -u root -p

Then change your password because having low strength password gives error sometimes.

ALTER USER 'root'@'localhost' IDENTIFIED BY 'new-strong-password';

FLUSH PRIVILEGES;

Then simply exit and again login with your new password:

quit

sudo mysql -u root -p

Once you successfully logged in type the command:

use mysql;

It should show a message like 'Database changed' then type:

UPDATE user SET plugin='mysql_native_password' WHERE User='root';

After that type:

UPDATE mysql.user set authentication_string=PASSWORD('new-strong-password') where user='root';

Then type:

FLUSH PRIVILEGES;

Then simply exit:

quit

Now try to log in with your new password in your WORKBENCH. Hope it will work. Thank you.

Something like gunzip using the -r flag?....

Travel the directory structure recursively. If any of the file names specified on the command line are directories, gzip will descend into the directory and compress all the files it finds there (or decompress them in the case of gunzip ).

The following might be a portable solution. It follows standards.

#include <iostream>
#include <fstream>
#include <string>
#include <cstdlib>
#include <sstream>

std::string ssystem (const char *command) {
    char tmpname [L_tmpnam];
    std::tmpnam ( tmpname );
    std::string scommand = command;
    std::string cmd = scommand + " >> " + tmpname;
    std::system(cmd.c_str());
    std::ifstream file(tmpname, std::ios::in | std::ios::binary );
    std::string result;
    if (file) {
        while (!file.eof()) result.push_back(file.get())
            ;
        file.close();
    }
    remove(tmpname);
    return result;
}

// For Cygwin

Use $http_MY_CUSTOM_HEADER

You can write some-thing like

set my_header $http_MY_CUSTOM_HEADER;
if($my_header != 'some-value') {
#do some thing;
}

The query will be something like:

SELECT 
  DATE_FORMAT(
    MIN(timestamp),
    '%d/%m/%Y %H:%i:00'
  ) AS tmstamp,
  name,
  COUNT(id) AS cnt 
FROM
  table
GROUP BY ROUND(UNIX_TIMESTAMP(timestamp) / 300), name

SASS (SCSS) triangle mixin

I wrote this to make it easier (and DRY) to automatically generate a CSS triangle:

// Triangle helper mixin (by Yair Even-Or)
// @param {Direction} $direction - either `top`, `right`, `bottom` or `left`
// @param {Color} $color [currentcolor] - Triangle color
// @param {Length} $size [1em] - Triangle size
@mixin triangle($direction, $color: currentcolor, $size: 1em) {
  $size: $size/2;
  $transparent: rgba($color, 0);
  $opposite: (top:bottom, right:left, left:right, bottom:top);

  content: '';
  display: inline-block;
  width: 0;
  height: 0;
  border: $size solid $transparent;
  border-#{map-get($opposite, $direction)}-color: $color;
  margin-#{$direction}: -$size;
}

use-case example:

span {
  @include triangle(bottom, red, 10px);
}

Playground page

Important note:
if the triangle seems pixelated in some browsers, try one of the methods described here.

You can use "index" if you only want to find a single character, e.g.:

LIST="server1 server2 server3 server4 server5"
SOURCE="3"
if expr index "$LIST" "$SOURCE"; then
    echo "match"
    exit -1
else
    echo "no match"
fi

Output is:

23
match

You should use System.Windows.Forms.Cursor.Position: "A Point that represents the cursor's position in screen coordinates."

I suggest this discriminative question:

Is the open-source tool necessary in your process of making money?

• a blog engine on your commercial web site is necessary: commercial use.
• winamp for listening to music is not necessary: non-commercial use.

Keep in mind this overwrites any ID that the element already has:

 $(".element").attr("id","SomeID");

The reason why addClass exists is because an element can have multiple classes, so you wouldn't want to necessarily overwrite the classes already set. But with most attributes, there is only one value allowed at any given time.

If you use chrome, you can make a shortcut,right click and edit the shortcut's target, append this after target's string:

--ignore-certificate-errors

The complete string looks like this:

"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --ignore-certificate-errors

Clickatell is a popular SMS gateway. It works in 200+ countries.

Their API offers a choice of connection options via: HTTP/S, SMPP, SMTP, FTP, XML, SOAP. Any of these options can be used from php.

The HTTP/S method is as simple as this:

http://api.clickatell.com/http/sendmsg?to=NUMBER&msg=Message+Body+Here

The SMTP method consists of sending a plain-text e-mail to: [email protected], with the following body:

user: xxxxx
password: xxxxx
api_id: xxxxx
to: 448311234567
text: Meet me at home

You can also test the gateway (incoming and outgoing) for free from your browser

If your query failed, you'll receive a FALSE return value. Otherwise you'll receive a resource/TRUE.

$result = mysql_query($query);

if(!$result){
    /* check for error, die, etc */
}

Basically as long as it's not false, you're fine. Afterwards, you can continue your code.

if(!$result)

This part of the code actually runs your query.

Assign the onclick like this:

divTag.onclick = printWorking;

The onclick property will not take a string when assigned. Instead, it takes a function reference (in this case, printWorking).
The onclick attribute can be a string when assigned in HTML, e.g. <div onclick="func()"></div>, but this is generally not recommended.

SequenceEqual will only return true if two conditions or met.

1. They contain the same elements.
2. The elements are in the same order.

If you only want to check if they contain the same elements regardless of their order and your problem is of the type

Does values2 contain all the values contained in values1?

you can use LINQ extension method Enumerable.Except and then check if the result has any value. Here's an example

int[] values1 = { 1, 2, 3, 4 };
int[] values2 = { 1, 2, 5 };
var result = values1.Except(values2);
if(result.Count()==0)
{
   //They are the same
}
else
{
    //They are different
}

And also by using this you get the different items as well automatically. Two birds with one stone.

Keep in mind, if you execute your code like this

var result = values2.Except(values1);

you will get different results.

In my case I have a local copy of an array and want to check if anything has been removed from the original array so I use this method.

You can download in the current directory with a . :

Late to the party, but might be of interest...

I find a combination of labs and guides specification useful in many cases:

You want nothing but a grid and a background:

ggplot(diamonds, mapping = aes(x = clarity)) + 
  geom_bar(aes(fill = cut)) + 
  labs(x = NULL, y = NULL) + 
  guides(x = "none", y = "none")

You want to only suppress the tick-mark label of one or both axes:

ggplot(diamonds, mapping = aes(x = clarity)) + 
  geom_bar(aes(fill = cut)) + 
  guides(x = "none", y = "none")

Usage:

select replace_foreign_key('user_rates_posts', 'post_id', 'ON DELETE CASCADE');

Function:

CREATE OR REPLACE FUNCTION 
    replace_foreign_key(f_table VARCHAR, f_column VARCHAR, new_options VARCHAR) 
RETURNS VARCHAR
AS $$
DECLARE constraint_name varchar;
DECLARE reftable varchar;
DECLARE refcolumn varchar;
BEGIN

SELECT tc.constraint_name, ccu.table_name AS foreign_table_name, ccu.column_name AS foreign_column_name 
FROM 
    information_schema.table_constraints AS tc 
    JOIN information_schema.key_column_usage AS kcu
      ON tc.constraint_name = kcu.constraint_name
    JOIN information_schema.constraint_column_usage AS ccu
      ON ccu.constraint_name = tc.constraint_name
WHERE constraint_type = 'FOREIGN KEY' 
   AND tc.table_name= f_table AND kcu.column_name= f_column
INTO constraint_name, reftable, refcolumn;

EXECUTE 'alter table ' || f_table || ' drop constraint ' || constraint_name || 
', ADD CONSTRAINT ' || constraint_name || ' FOREIGN KEY (' || f_column || ') ' ||
' REFERENCES ' || reftable || '(' || refcolumn || ') ' || new_options || ';';

RETURN 'Constraint replaced: ' || constraint_name || ' (' || f_table || '.' || f_column ||
 ' -> ' || reftable || '.' || refcolumn || '); New options: ' || new_options;

END;
$$ LANGUAGE plpgsql;

Be aware: this function won't copy attributes of initial foreign key. It only takes foreign table name / column name, drops current key and replaces with new one.

I had the same issue of multiple DocumentCompleted fired events and tried out all the suggestions above. Finally, seems that in my case neither IsBusy property works right nor Url property, but the ReadyState seems to be what I needed, because it has the status 'Interactive' while loading the multiple frames and it gets the status 'Complete' only after loading the last one. Thus, I know when the page is fully loaded with all its components.

I hope this may help others too :)

jQuery is required ;-)

While creating the matrix X and Y vector use values.

X=dataset.iloc[:,4].values
Y=dataset.iloc[:,0:4].values

It will definitely solve your problem.

I also got a similar error when forced to use TLS1.2 for java 6. And I handled it thanks to this library:

1. Clone Source Code: https://github.com/tobszarny/ssl-provider-jvm16

2. Add Main Class:

   public static void main(String[] args) throws Exception {
       try {
           String apiUrl = "https://domain/api/query?test=123";
   
           URL myurl = new URL(apiUrl);
           HttpsURLConnection con = (HttpsURLConnection) myurl.openConnection();
           con.setSSLSocketFactory(new TSLSocketConnectionFactory());
           int responseCode = con.getResponseCode();
           System.out.println("GET Response Code :: " + responseCode);
       } catch (Exception ex) {
           ex.printStackTrace();
       }
   }
   

You can use Double.parseDouble() to convert a String to a double:

String text = "12.34"; // example String
double value = Double.parseDouble(text);

For your case it looks like you want:

double total = Double.parseDouble(jlbTotal.getText());
double price = Double.parseDouble(jlbPrice.getText());

Volatile means other threads can edit that particular variable. So the compiler allows access to them.

http://www.javamex.com/tutorials/synchronization_volatile.shtml

Transient means that when you serialize an object, it will return its default value on de-serialization

http://www.geekinterview.com/question_details/2

You can only use await in an async method, and Main cannot be async.

You'll have to use your own async-compatible context, call Wait on the returned Task in the Main method, or just ignore the returned Task and just block on the call to Read. Note that Wait will wrap any exceptions in an AggregateException.

If you want a good intro, see my async/await intro post.

//See this:


// global var, naming bB
var bB = 5;

//  Dependency Injection cokntroller
var a = function(str, fn) {
  //stringify function body
  var fnStr = fn.toString();

  // Key: get form args to string
  var args = fnStr.match(/function\s*\((.*?)\)/);
  // 
  console.log(args);
  // if the form arg is 'bB', then exec it, otherwise, do nothing
  for (var i = 0; i < args.length; i++) {
    if(args[i] == 'bB') {
      fn(bB);
    }
  }
}
// will do nothing
a('sdfdfdfs,', function(some){
alert(some)
});
// will alert 5

a('sdfdsdsfdfsdfdsf,', function(bB){
alert(bB)
});

// see, this shows you how to get function args in string

Try http://www.sql-server-helper.com/tips/date-formats.aspx. Lists all formats needed. In this case select Convert(varchar(10),CONVERT(date,YourDateColumn,106),103) change 103 to 104 id you need dd.mm.yyyy

From a relational database theory point of view, there should be absolutely no problem on updating the primary key of a table, provided that there are no duplicates among the primary keys and that you do not try to put a NULL value in any of the primary key columns.

I have overcome this problem by changing the device screen size.

I have found that if you are specifying 1024 mb ram then you have to specify the device screen size in hdpi only and if it is 512 mb ram then it should be mdpi or others.

So, We can clearly say that ram size should be specify according to the screen size . If you are specifying the 1024 ram size while keeping the device screen size in mdpi then it results in the above mentioned error i.e "Failed to allocate memory: 8 This application has requested the Runtime to terminate it in an unusual way.

Please contact the application's support team for more information."

make your options in AVD manager as follows:

[2013-01-11 14:44:01 - SDK Manager] hw.sensors.orientation=yes

[2013-01-11 14:44:01 - SDK Manager] hw.camera.front=none

[2013-01-11 14:44:01 - SDK Manager] hw.gps=yes

[2013-01-11 14:44:01 - SDK Manager] skin.dynamic=no

[2013-01-11 14:44:01 - SDK Manager] hw.keyboard=no

[2013-01-11 14:44:01 - SDK Manager] vm.heapSize=32

[2013-01-11 14:44:01 - SDK Manager] hw.ramSize=343

getline, as it name states, read a whole line, or at least till a delimiter that can be specified.

So the answer is "no", getlinedoes not match your need.

But you can do something like:

inFile >> first_name >> last_name >> age;
name = first_name + " " + last_name;

You must sort your data according your needs (es. in reverse order) and use select top query

I got it done by only encoding the output using utf-8. Here is the code example

new_tweets = api.GetUserTimeline(screen_name = user,count=200)
result = new_tweets[0]
try: text = result.text
except: text = ''

with open(file_name, 'a', encoding='utf-8') as f:
    writer = csv.writer(f)
    writer.writerows(text)

i.e: do not encode when collecting data from api, encode the output (print or write) only.

Function pointer is usually defined by typedef, and used as param & return value.

Above answers already explained a lot, I just give a full example:

#include <stdio.h>

#define NUM_A 1
#define NUM_B 2

// define a function pointer type
typedef int (*two_num_operation)(int, int);

// an actual standalone function
static int sum(int a, int b) {
    return a + b;
}

// use function pointer as param,
static int sum_via_pointer(int a, int b, two_num_operation funp) {
    return (*funp)(a, b);
}

// use function pointer as return value,
static two_num_operation get_sum_fun() {
    return &sum;
}

// test - use function pointer as variable,
void test_pointer_as_variable() {
    // create a pointer to function,
    two_num_operation sum_p = &sum;
    // call function via pointer
    printf("pointer as variable:\t %d + %d = %d\n", NUM_A, NUM_B, (*sum_p)(NUM_A, NUM_B));
}

// test - use function pointer as param,
void test_pointer_as_param() {
    printf("pointer as param:\t %d + %d = %d\n", NUM_A, NUM_B, sum_via_pointer(NUM_A, NUM_B, &sum));
}

// test - use function pointer as return value,
void test_pointer_as_return_value() {
    printf("pointer as return value:\t %d + %d = %d\n", NUM_A, NUM_B, (*get_sum_fun())(NUM_A, NUM_B));
}

int main() {
    test_pointer_as_variable();
    test_pointer_as_param();
    test_pointer_as_return_value();

    return 0;
}

This worked for me

ffmpeg -i file.mp4 -vf fps=1 %d.jpg

The hashes are just because your column width is not enough to display the "number".

About the sorting, you should review how you system region and language is configured. For the US region, Excel date input should be "5/17/2012" not "17/05/2012" (this 17-may-12).

Ok, so the easiest method to create several plots is this:

import matplotlib.pyplot as plt
x=[[1,2,3,4],[1,2,3,4],[1,2,3,4],[1,2,3,4]]
y=[[1,2,3,4],[1,2,3,4],[1,2,3,4],[1,2,3,4]]
for i in range(len(x)):
    plt.figure()
    plt.plot(x[i],y[i])
    # Show/save figure as desired.
    plt.show()
# Can show all four figures at once by calling plt.show() here, outside the loop.
#plt.show()

Note that you need to create a figure every time or pyplot will plot in the first one created.

If you want to create several data series all you need to do is:

import matplotlib.pyplot as plt
plt.figure()
x=[[1,2,3,4],[1,2,3,4],[1,2,3,4],[1,2,3,4]]
y=[[1,2,3,4],[2,3,4,5],[3,4,5,6],[7,8,9,10]]
plt.plot(x[0],y[0],'r',x[1],y[1],'g',x[2],y[2],'b',x[3],y[3],'k')

You could automate it by having a list of colours like ['r','g','b','k'] and then just calling both entries in this list and corresponding data to be plotted in a loop if you wanted to. If you just want to programmatically add data series to one plot something like this will do it (no new figure is created each time so everything is plotted in the same figure):

import matplotlib.pyplot as plt
x=[[1,2,3,4],[1,2,3,4],[1,2,3,4],[1,2,3,4]]
y=[[1,2,3,4],[2,3,4,5],[3,4,5,6],[7,8,9,10]]
colours=['r','g','b','k']
plt.figure() # In this example, all the plots will be in one figure.    
for i in range(len(x)):
    plt.plot(x[i],y[i],colours[i])
plt.show()

Hope this helps. If anything matplotlib has a very good documentation page with plenty of examples.

17 Dec 2019: added plt.show() and plt.figure() calls to clarify this part of the story.

   self.tableView.tableHeaderView = segmentedControl; 

If you want it to obey your width and height properly though enclose your segmentedControl in a UIView first as the tableView likes to mangle your view a bit to fit the width.

Copy isn't useless if you imagine the use case to copy some values into an existing collection. I.e. you want to overwrite existing elements instead of inserting.

An example: a = [1,2,3,4,5] b = [2,2,2,2,3,3,3,3,3,4,4,4,] a.copy(b) = [1,2,3,4,5,3,3,3,3,4,4,4]

However I'd expect a copy method that would take additional parameters for the start index of the source and target collection, as well as a parameter for count.

See Java BUG 6350752

For using the new progress bar

style="?android:attr/progressBarStyleHorizontal"

for the old grey color progress bar use

style="@android:style/Widget.ProgressBar.Horizontal"

in this one you have the option of changing the height by setting minHeight

The complete XML code is:

    <ProgressBar
    android:id="@+id/pbProcessing"
    style="?android:attr/progressBarStyleHorizontal"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_below="@+id/tvProcessing"
    android:indeterminateOnly="true"/>

indeterminateOnly is set to true for getting indeterminate horizontal progress bar

Go to "Run" and execute this:

%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -ir

NOTE: run as administrator.

I modified your solution to chain over multiple properties:

public static string GetPropertyName<T>(Expression<Func<T>> propertyLambda)
{
    MemberExpression me = propertyLambda.Body as MemberExpression;
    if (me == null)
    {
        throw new ArgumentException("You must pass a lambda of the form: '() => Class.Property' or '() => object.Property'");
    }

    string result = string.Empty;
    do
    {
        result = me.Member.Name + "." + result;
        me = me.Expression as MemberExpression;
    } while (me != null);

    result = result.Remove(result.Length - 1); // remove the trailing "."
    return result;
}

Usage:

string name = GetPropertyName(() => someObject.SomeProperty.SomeOtherProperty);
// returns "SomeProperty.SomeOtherProperty"

It's caused by n % x where x = 0 in the first loop iteration. You can't calculate a modulus with respect to 0.

Simply run on terminal : sudo chown -R $(whoami) ~/.npm

This worked for me !!

Doing Project -> Clean... fixed it for me.

My eclipse had stopped working so I cleaned workspace directory and after I run eclipse when I import the project I had this problem. Other solutions suggested here didn't work.

        public FilteredRequest(ServletRequest request) {
            super((HttpServletRequest)request);

            for (int i = 0; i < input.length(); i++) {
                if (allowedChars.indexOf(input.charAt(i)) >= 0) {
                    result += input.charAt(i);

['C', '8/1/2014', '30000', '28960', 'N']
<class 'list'>


you can convert a dataframe to a nested list
[['A', '1/1/2014', '1000', '4000', 'Y'], ['A', '2/1/2014', '12000', '10000', 'Y'], ['A', '3/1/2014', '36000', '2000', 'Y'], ['B', '4/1/2014', '15000', '10000', 'N'], ['B', '4/1/2014', '12000', '11500', 'N'], ['B', '4/1/2014', '90000', '11000', 'N'], ['C', '7/1/2014', '22000', '18000', 'N'], ['C', '8/1/2014', '30000', '28960', 'N'], ['C', '9/1/2014', '53000', '51200', 'N']]
<class 'list'>

the content of a dataframe can be accessed as a numpy.ndarray
[['A' '1/1/2014' '1000' '4000' 'Y']
 ['A' '2/1/2014' '12000' '10000' 'Y']

as pointed out by cs95 other methods should be preferred over pandas .values attribute from pandas version 0.24 on see here. I use it here, because most people will (by 2019) still have an older version, which does not support the new recommendations. You can check your version with print(pd.__version__)

You need to tell it which index in data to use, or double loop through all.

E.g., to get the values in the 4th index in the outside array.:

foreach($user->data[3]->values as $values)
{
     echo $values->value . "\n";
}

To go through all:

foreach($user->data as $mydata)
{
    foreach($mydata->values as $values) {
        echo $values->value . "\n";
    }

}   

Datatype: array_name:datatype[]=[]; Example string: users:string[]=[];

For array of objects:

Objecttype: object_name:objecttype[]=[{}]; Example user: Users:user[]=[{}];

And if in some cases it's coming undefined in binding, make sure to initialize it on Oninit().

I clicked on this button and it worked for me.

Here is the screenshot

First of all, this approach won't scale in the large, you'll need a separate index from words to item (like an inverted index).

If your data is not large, you can do

SELECT DISTINCT(name) FROM mytable WHERE name LIKE '%mall%' OR description LIKE '%mall%'

using OR if you have multiple keywords.

I recently had the requirement to use JNDI with an embedded Tomcat in Spring Boot.
Actual answers give some interesting hints to solve my task but it was not enough as probably not updated for Spring Boot 2.

Here is my contribution tested with Spring Boot 2.0.3.RELEASE.

Specifying a datasource available in the classpath at runtime

You have multiple choices :

• using the DBCP 2 datasource (you don't want to use DBCP 1 that is outdated and less efficient).
• using the Tomcat JDBC datasource.
• using any other datasource : for example HikariCP.

If you don't specify anyone of them, with the default configuration the instantiation of the datasource will throw an exception :

• To use Apache JDBC datasource, you don't need to add any dependency but you have to change the default factory class to org.apache.tomcat.jdbc.pool.DataSourceFactory.
  You can do it in the resource declaration : resource.setProperty("factory", "org.apache.tomcat.jdbc.pool.DataSourceFactory"); I will explain below where add this line.

• To use DBCP 2 datasource a dependency is required:

  <dependency> <groupId>org.apache.tomcat</groupId> <artifactId>tomcat-dbcp</artifactId> <version>8.5.4</version> </dependency>

Of course, adapt the artifact version according to your Spring Boot Tomcat embedded version.

• To use HikariCP, add the required dependency if not already present in your configuration (it may be if you rely on persistence starters of Spring Boot) such as :

  <dependency> <groupId>com.zaxxer</groupId> <artifactId>HikariCP</artifactId> <version>3.1.0</version> </dependency>

and specify the factory that goes with in the resource declaration:

resource.setProperty("factory", "com.zaxxer.hikari.HikariJNDIFactory");

Datasource configuration/declaration

You have to customize the bean that creates the TomcatServletWebServerFactory instance.
Two things to do :

• enabling the JNDI naming which is disabled by default

• creating and add the JNDI resource(s) in the server context

For example with PostgreSQL and a DBCP 2 datasource, do that :

@Bean
public TomcatServletWebServerFactory tomcatFactory() {
    return new TomcatServletWebServerFactory() {
        @Override
        protected TomcatWebServer getTomcatWebServer(org.apache.catalina.startup.Tomcat tomcat) {
            tomcat.enableNaming(); 
            return super.getTomcatWebServer(tomcat);
        }

        @Override 
        protected void postProcessContext(Context context) {

            // context
            ContextResource resource = new ContextResource();
            resource.setName("jdbc/myJndiResource");
            resource.setType(DataSource.class.getName());
            resource.setProperty("driverClassName", "org.postgresql.Driver");

            resource.setProperty("url", "jdbc:postgresql://hostname:port/dbname");
            resource.setProperty("username", "username");
            resource.setProperty("password", "password");
            context.getNamingResources()
                   .addResource(resource);          
        }
    };
}

Here the variants for Tomcat JDBC and HikariCP datasource.

In postProcessContext() set the factory property as explained early for Tomcat JDBC ds :

    @Override 
    protected void postProcessContext(Context context) {
        ContextResource resource = new ContextResource();       
        //...
        resource.setProperty("factory", "org.apache.tomcat.jdbc.pool.DataSourceFactory");
        //...
        context.getNamingResources()
               .addResource(resource);          
    }
};

and for HikariCP :

    @Override 
    protected void postProcessContext(Context context) {
        ContextResource resource = new ContextResource();       
        //...
        resource.setProperty("factory", "com.zaxxer.hikari.HikariDataSource");
        //...
        context.getNamingResources()
               .addResource(resource);          
    }
};

Using/Injecting the datasource

You should now be able to lookup the JNDI ressource anywhere by using a standard InitialContext instance :

InitialContext initialContext = new InitialContext();
DataSource datasource = (DataSource) initialContext.lookup("java:comp/env/jdbc/myJndiResource");

You can also use JndiObjectFactoryBean of Spring to lookup up the resource :

JndiObjectFactoryBean bean = new JndiObjectFactoryBean();
bean.setJndiName("java:comp/env/jdbc/myJndiResource");
bean.afterPropertiesSet();
DataSource object = (DataSource) bean.getObject();

To take advantage of the DI container you can also make the DataSource a Spring bean :

@Bean(destroyMethod = "")
public DataSource jndiDataSource() throws IllegalArgumentException, NamingException {
    JndiObjectFactoryBean bean = new JndiObjectFactoryBean();
    bean.setJndiName("java:comp/env/jdbc/myJndiResource");
    bean.afterPropertiesSet();
    return (DataSource) bean.getObject();
}

And so you can now inject the DataSource in any Spring beans such as :

@Autowired
private DataSource jndiDataSource;

Note that many examples on the internet seem to disable the lookup of the JNDI resource on startup :

bean.setJndiName("java:comp/env/jdbc/myJndiResource");
bean.setProxyInterface(DataSource.class);
bean.setLookupOnStartup(false);
bean.afterPropertiesSet(); 

But I think that it is helpless as it invokes just after afterPropertiesSet() that does the lookup !

Check out Google Collections' Multimap, e.g. page 28 of this presentation.

If you can't use that library for some reason, consider using ConcurrentHashMap instead of SynchronizedHashMap; it has a nifty putIfAbsent(K,V) method with which you can atomically add the element list if it's not already there. Also, consider using CopyOnWriteArrayList for the map values if your usage patterns warrant doing so.

cd /home/www && find . -type f -print0 |
  xargs -0 perl -i.bak -pe 's/subdomainA\.example\.com/subdomainB.example.com/g'

Try the following:

str1="2345";
int x=str1.charAt(2)-'0';
//here x=4;

if u subtract by char '0', the ASCII value needs not to be known.

You cannot do new T() due to type erasure. The default constructor can only be

public Navigation() {     this("", "", null); } 

​ You can create other constructors to provide default values for trigger and description. You need an concrete object of T.

You should be able to do this with a pretty standard DAO recordset loop. You can see some examples at the following links:
http://msdn.microsoft.com/en-us/library/bb243789%28v=office.12%29.aspx
http://www.granite.ab.ca/access/email/recordsetloop.htm

My own standard loop looks something like this:

Dim rs As DAO.Recordset
Set rs = CurrentDb.OpenRecordset("SELECT * FROM Contacts")

'Check to see if the recordset actually contains rows
If Not (rs.EOF And rs.BOF) Then
    rs.MoveFirst 'Unnecessary in this case, but still a good habit
    Do Until rs.EOF = True
        'Perform an edit
        rs.Edit
        rs!VendorYN = True
        rs("VendorYN") = True 'The other way to refer to a field
        rs.Update

        'Save contact name into a variable
        sContactName = rs!FirstName & " " & rs!LastName

        'Move to the next record. Don't ever forget to do this.
        rs.MoveNext
    Loop
Else
    MsgBox "There are no records in the recordset."
End If

MsgBox "Finished looping through records."

rs.Close 'Close the recordset
Set rs = Nothing 'Clean up

It's a linefeed character. How you use it would be up to you.

If you need an index on the sha1 column, I suggest CHAR(40) for performance reasons. In my case the sha1 column is an email confirmation token, so on the landing page the query enters only with the token. In this case CHAR(40) with INDEX, in my opinion, is the best choice :)

If you want to adopt this method, remember to leave $raw_output = false.

Another thing that people may find useful when using the develop method is the --user option to install without sudo. Ex:

python setup.py develop --user

instead of

sudo python setup.py develop

There is no hard and fast rule.

Here are some rules to make code thread safe in .NET and why these are not good rules:

1. Function and all functions it calls must be pure (no side effects) and use local variables. Although this will make your code thread-safe, there is also very little amount of interesting things you can do with this restriction in .NET.
2. Every function that operates on a common object must lock on a common thing. All locks must be done in same order. This will make the code thread safe, but it will be incredibly slow, and you might as well not use multiple threads.
3. ...

There is no rule that makes the code thread safe, the only thing you can do is make sure that your code will work no matter how many times is it being actively executed, each thread can be interrupted at any point, with each thread being in its own state/location, and this for each function (static or otherwise) that is accessing common objects.

This issue is related to network connectivity if not solved adding maven { url "http://jcenter.bintray.com"} at project level.

Just try to change your network and sync the gradle, should fix this issue for sure.

No, don't do it that way.

From your Eclipse workspace, right click your project on the left pane -> Properties -> Java Build Path -> Add Jars -> add your jars here.

Tadaa!! :)

I realized that by looking at the stack trace it was trying to load my own script in place of another module called the same way,i.e., my script was called random.py and when a module i used was trying to import the "random" package, it was loading my script causing a circular reference and so i renamed it and deleted a .pyc file it had created from the working folder and things worked just fine.

As Apple has changed how you can access any user private data types in iOS 10.

You need to add the "Privacy - Camera usage description" key to your app’s Info.plist and their usage information which is apply for your application, as in below example I had provided that I have used to scan barcodes.

For more information please find the below screenshot.

Depending on how you can organize your code, another option can be to put the environment variable within a function that's executed at runtime.

In this file, the environment variable is set at import time and requires dynamic requires in order to test different environment variables (as described in this answer):

const env = process.env.MY_ENV_VAR;

const envMessage = () => `MY_ENV_VAR is set to ${env}!`;

export default myModule;

In this file, the environment variable is set at envMessage execution time, and you should be able to mutate process.env directly in your tests:

const envMessage = () => {
  const env = process.env.MY_VAR;
  return `MY_ENV_VAR is set to ${env}!`;
}

export default myModule;

Jest test:

const vals = [
  'ONE',
  'TWO',
  'THREE',
];

vals.forEach((val) => {
  it(`Returns the correct string for each ${val} value`, () => {
    process.env.MY_VAR = val;

    expect(envMessage()).toEqual(...

You need to be aware that Excel is very sensitive to the culture you are running under as well.

You may find that you need to set the culture to EN-US before calling Excel functions. This does not apply to all functions - but some of them.

    CultureInfo en_US = new System.Globalization.CultureInfo("en-US"); 
    System.Threading.Thread.CurrentThread.CurrentCulture = en_US;
    string filePathLocal = _applicationObject.ActiveWorkbook.Path;
    System.Threading.Thread.CurrentThread.CurrentCulture = orgCulture;

This applies even if you are using VSTO.

You should create a XML file for the disabled button (drawable/btn_disable.xml)

<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid android:color="@color/grey" />
    <corners android:radius="6dp" />
</shape>

And create a selector for the button (drawable/btn_selector.xml)

<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:drawable="@drawable/btn_disable" android:state_enabled="false"/>
    <item android:drawable="@drawable/btn_default" android:state_enabled="true"/>
    <item android:drawable="@drawable/btn_default" android:state_pressed="false" />

</selector>

Add the selector to your button

<style name="srp_button" parent="@android:style/Widget.Button">
    <item name="android:background">@drawable/btn_selector</item>
</style>

As mentioned, the difference is primarily the size of the underlying variables, which in each case get larger to allow more characters to be represented.

However, fonts, encoding and things are wickedly complicated (unnecessarily?), so a big link is needed to fill in more detail:

Don't expect to understand it all, but if you don't want to have problems later it's worth learning as much as you can, as early as you can (or just getting someone else to sort it out for you).

Paul.

The simple way to do that is by command

adb install example.apk

and if you want to target connect device you can add parameter " -d "

adb install -d example.apk

if you have more than one device/emulator connected you will get this error

adb: error: connect failed: more than one device/emulator - waiting for device - error: more than one device/emulator

to avoid that you can list all devices by below command

adb devices

you will get results like below

 C:\Windows\System32>adb devices 
 List of devices attached 
 a3b09hh3e    device 
 emulator-5334    device

chose one of these devices and add parameter to adb command as " -s a3b09hh3e " as below

adb -s a3b09a6e install  example.apk

also as a hint if the path of the apk long and have a spaces, just add it between double quotes like

adb -s a3b09a6e install  "c:\my apk location\here 123\example.apk"

try this code

Intent photo= new Intent("android.media.action.IMAGE_CAPTURE");
                    startActivityForResult(photo, CAMERA_PIC_REQUEST);

jsonify serializes the data you pass it to JSON. If you want to serialize the data yourself, do what jsonify does by building a response with status=200 and mimetype='application/json'.

from flask import json

@app.route('/summary')
def summary():
    data = make_summary()
    response = app.response_class(
        response=json.dumps(data),
        status=200,
        mimetype='application/json'
    )
    return response

try this:

#outer {
    width:500px; 
    height:200px; 
    background:#FFCCCC;
    margin:50px auto 0 auto;
    display:table;
}
#inner {
    background:#FFCC33;
    margin:50px 50px 50px 50px;
    padding:10px;
    display:block;
}?

Good luck

If your code cannot be updated on some reason, just change your switch ... continue to switch ... break, as in previous versions of PHP it was meant to work this way.

r = requests.get('https://api.github.com', auth=('user', 'pass'))

r is a response. It has a request attribute which has the information you need.

r.request.allow_redirects  r.request.headers          r.request.register_hook
r.request.auth             r.request.hooks            r.request.response
r.request.cert             r.request.method           r.request.send
r.request.config           r.request.params           r.request.sent
r.request.cookies          r.request.path_url         r.request.session
r.request.data             r.request.prefetch         r.request.timeout
r.request.deregister_hook  r.request.proxies          r.request.url
r.request.files            r.request.redirect         r.request.verify

r.request.headers gives the headers:

{'Accept': '*/*',
 'Accept-Encoding': 'identity, deflate, compress, gzip',
 'Authorization': u'Basic dXNlcjpwYXNz',
 'User-Agent': 'python-requests/0.12.1'}

Then r.request.data has the body as a mapping. You can convert this with urllib.urlencode if they prefer:

import urllib
b = r.request.data
encoded_body = urllib.urlencode(b)

depending on the type of the response the .data-attribute may be missing and a .body-attribute be there instead.

It turns out that it was shrinking and growing correctly, providing the desired behaviour all along; except that in all current browsers flexbox wasn't accounting for the vertical scrollbar! Which is why the content appears to be getting cut off.

You can see here, which is the original code I was using before I added the fixed widths, that it looks like the column isn't growing to accomodate the text:

However if you make the content in that column wider, you'll see that it always cuts it off by the same amount, which is the width of the scrollbar.

So the fix is very, very simple - add enough right padding to account for the scrollbar:

http://jsfiddle.net/2w157dyL/2/

  main > section {_x000D_
    overflow-y: auto;_x000D_
    padding-right: 2em;_x000D_
  }

It was when I was trying some things suggested by Michael_B (specifically adding a padding buffer) that I discovered this, thanks so much!

Edit: I see that he also posted a fiddle which does the same thing - again, thanks so much for all your help

Android NDK official hello-libs CMake example

https://github.com/googlesamples/android-ndk/tree/840858984e1bb8a7fab37c1b7c571efbe7d6eb75/hello-libs

Just worked for me on Ubuntu 17.10 host, Android Studio 3, Android SDK 26, so I strongly recommend that you base your project on it.

The shared library is called libgperf, the key code parts are:

• hello-libs/app/src/main/cpp/CMakeLists.txt:

  // -L
  add_library(lib_gperf SHARED IMPORTED)
  set_target_properties(lib_gperf PROPERTIES IMPORTED_LOCATION
            ${distribution_DIR}/gperf/lib/${ANDROID_ABI}/libgperf.so)
  
  // -I
  target_include_directories(hello-libs PRIVATE
                             ${distribution_DIR}/gperf/include)
  // -lgperf
  target_link_libraries(hello-libs
                        lib_gperf)
  

• app/build.gradle:

  android {
      sourceSets {
          main {
              // let gradle pack the shared library into apk
              jniLibs.srcDirs = ['../distribution/gperf/lib']
  

  Then, if you look under /data/app on the device, libgperf.so will be there as well.

• on C++ code, use: #include <gperf.h>

• header location: hello-libs/distribution/gperf/include/gperf.h

• lib location: distribution/gperf/lib/arm64-v8a/libgperf.so

• If you only support some architectures, see: Gradle Build NDK target only ARM

The example git tracks the prebuilt shared libraries, but it also contains the build system to actually build them as well: https://github.com/googlesamples/android-ndk/tree/840858984e1bb8a7fab37c1b7c571efbe7d6eb75/hello-libs/gen-libs

This should work.

DisplayMetrics dm = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);
int width = dm.widthPixels; //320
int height = dm.heightPixels; //480

 import moment from 'moment';
 .....

  render() {
   return (
    <div>
        { 
        this.props.data.map((post,key) => 
            <div key={key} className="post-detail">
                <h1>{post.title}</h1>
                <p>{moment(post.date).calendar()}</p>
                <p dangerouslySetInnerHTML={{__html: post.content}}></p>
                <hr />
            </div>
        )}
    </div>
   );
  }

lapsList() {

    return this.state.laps.map((data) => {
      return (
        <View><Text>{data.time}</Text></View>
      )
    })
}

You forgot to return the map. this code will resolve the issue.

The easiest way would be

Section = 'Sec_' + Section

But for efficiency, see: https://waymoot.org/home/python_string/

This link just gave me the best answer:

$ wget --no-clobber --convert-links --random-wait -r -p --level 1 -E -e robots=off -U mozilla http://base.site/dir/

Worked like a charm.

Another solution: use flexjson.jar: http://mvnrepository.com/artifact/net.sf.flexjson/flexjson/3.2

List<yourEntity> yourEntityList = deserializer.deserialize(new InputStreamReader(input));

Starting with Bootstrap v3.3.0 you can use .media-left and .media-body

<div class="media">
    <span class="media-left">
        <img src="../site/img/success32.png" alt="...">
    </span>
    <div class="media-body">
        <h3 class="media-heading">Experience</h3>
        ...
    </div>
</div>

None of those worked for me. I was trying to clone a directory from a private git server and entered my credentials false and then it wouldn't let me try different credentials on subsequent tries, it just errored out immediately with an authentication error.

What did work was specifying the user name (mike-wise)in the url like this:

   git clone https://[email protected]/someuser/somerepo.git

For IE10+ standard conditions don't work cause of engine change or some another reasons, cause, you know, it's MSIE. But for IE10+ you need to run something like this in your scripts:

if (navigator.userAgent.match(/Trident\/7\./)) {
  // do stuff for IE.
}

On Windows 10 Anniversary Update, it's even easier to run shell commands in/with bash on ubuntu on windows

I was trying to set my region for my x-wrt r7000 netgear router, I found the following worked for me, using bash on ubuntu on windows, you do have to enable subsystem found in windows features, and dev mode on

ssh [email protected] < /mnt/c/ccode-eu.sh

For any of the JSON parse, use the website http://json2csharp.com/ (easiest way) to convert your JSON into C# class to deserialize your JSON into C# object.

 public class JSONClass
 {
        public string name { get; set; }
        public string url { get; set; }
        public bool visibility { get; set; }
        public string idField { get; set; }
        public bool defaultEvents { get; set; }
        public string type { get; set; }        
 }

Then use the JavaScriptSerializer (from System.Web.Script.Serialization), in case you don't want any third party DLL like newtonsoft.

using (StreamReader r = new StreamReader("jsonfile.json"))
{
   string json = r.ReadToEnd();
   JavaScriptSerializer jss = new JavaScriptSerializer();
   var Items = jss.Deserialize<JSONClass>(json);
}

Then you can get your object with Items.name or Items.Url etc.

you have to make a custom object where you used a UIView and inside you put a UIImageView and a UILabel

I solve this issue the following: style="?android:attr/ratingBarStyleSmall"

Without sharex=True, sharey=True you get:

With it you should get it nicer:

fig, axes2d = plt.subplots(nrows=3, ncols=3,
                           sharex=True, sharey=True,
                           figsize=(6,6))

for i, row in enumerate(axes2d):
    for j, cell in enumerate(row):
        cell.imshow(np.random.rand(32,32))

plt.tight_layout()

But if you want to add additional labels, you should add them only to the edge plots:

fig, axes2d = plt.subplots(nrows=3, ncols=3,
                           sharex=True, sharey=True,
                           figsize=(6,6))

for i, row in enumerate(axes2d):
    for j, cell in enumerate(row):
        cell.imshow(np.random.rand(32,32))
        if i == len(axes2d) - 1:
            cell.set_xlabel("noise column: {0:d}".format(j + 1))
        if j == 0:
            cell.set_ylabel("noise row: {0:d}".format(i + 1))

plt.tight_layout()

Adding label for each plot would spoil it (maybe there is a way to automatically detect repeated labels, but I am not aware of one).

The notion of complex numbers was introduced in mathematics, from the need of calculating negative quadratic roots. Complex number concept was taken by a variety of engineering fields.

Today that complex numbers are widely used in advanced engineering domains such as physics, electronics, mechanics, astronomy, etc...

Real and imaginary part, of a negative square root example:

#include <stdio.h>   
#include <complex.h>

int main() 
{
    int negNum;

    printf("Calculate negative square roots:\n"
           "Enter negative number:");

    scanf("%d", &negNum);

    double complex negSqrt = csqrt(negNum);

    double pReal = creal(negSqrt);
    double pImag = cimag(negSqrt);

    printf("\nReal part %f, imaginary part %f"
           ", for negative square root.(%d)",
           pReal, pImag, negNum);

    return 0;
}

Assuming you're the administrator of the machine, Ubuntu has granted you the right to sudo to run any command as any user.
Also assuming you did not restrict the rights in the pg_hba.conf file (in the /etc/postgresql/9.1/main directory), it should contain this line as the first rule:

# Database administrative login by Unix domain socket  
local   all             postgres                                peer

(About the file location: 9.1 is the major postgres version and main the name of your "cluster". It will differ if using a newer version of postgres or non-default names. Use the pg_lsclusters command to obtain this information for your version/system).

Anyway, if the pg_hba.conf file does not have that line, edit the file, add it, and reload the service with sudo service postgresql reload.

Then you should be able to log in with psql as the postgres superuser with this shell command:

sudo -u postgres psql

Once inside psql, issue the SQL command:

ALTER USER postgres PASSWORD 'newpassword';

In this command, postgres is the name of a superuser. If the user whose password is forgotten was ritesh, the command would be:

ALTER USER ritesh PASSWORD 'newpassword';

References: PostgreSQL 9.1.13 Documentation, Chapter 19. Client Authentication

Keep in mind that you need to type postgres with a single S at the end

If leaving the password in clear text in the history of commands or the server log is a problem, psql provides an interactive meta-command to avoid that, as an alternative to ALTER USER ... PASSWORD:

\password username

It asks for the password with a double blind input, then hashes it according to the password_encryption setting and issue the ALTER USER command to the server with the hashed version of the password, instead of the clear text version.

Based on this forum post: https://groups.google.com/forum/#!topic/ggplot2/mK9DR3dKIBU

Sounds like the easiest thing to do is to add a line break (\n) before your x axis, and after your y axis labels. Seems a lot easier (although dumber) than the solutions posted above.

ggplot(mpg, aes(cty, hwy)) + 
    geom_point() + 
    xlab("\nYour_x_Label") + ylab("Your_y_Label\n")

Hope that helps!

There is an Euclid's algorithm for GCD,

public int GCF(int a, int b) {
    if (b == 0) return a;
    else return (GCF (b, a % b));
}

By the way, a and b should be greater or equal 0, and LCM = |ab| / GCF(a, b)

You will have to use JavaScript. The browser will only send the value of the selected option (so its not PHP's fault).

What your JS should do is hook into the form's submit event and create a hidden field with the value of the selected option's stud_name value. This hidden field will then get sent to the server.

That being said ... you shouldn't relay on the client to provide the correct data. You already know what stud_name should be for a given value on the server (since you are outputting it). So just apply the same logic when you are processing the form.

Have you ever heard of Promises? They work on all modern browsers and are relatively simple to use. Have a look at this simple method to inject css to the html head:

function loadStyle(src) {
    return new Promise(function (resolve, reject) {
        let link = document.createElement('link');
        link.href = src;
        link.rel = 'stylesheet';

        link.onload = () => resolve(link);
        link.onerror = () => reject(new Error(`Style load error for ${src}`));

        document.head.append(link);
    });
}

You can implement it as follows:

window.onload = function () {
    loadStyle("https://fonts.googleapis.com/css2?family=Raleway&display=swap")
        .then(() => loadStyle("css/style.css"))
        .then(() => loadStyle("css/icomoon.css"))
        .then(() => {
            alert('All styles are loaded!');
        }).catch(err => alert(err));
}

It's really cool, right? This is a way to decide the priority of the styles using Promises.

To see a multi-style loading implementation see: https://stackoverflow.com/a/63936671/13720928

the point can be if you are not using valid login for linked server. Problem is on destination server side.

There are few steps to try:

1. Align db user and login on destination server: alter user [DBUSER_of_linkedserverlogin] with login = [linkedserverlogin]

2. recreate login on destination server used by linked server.

3. Backup table and recreate it.

2nd resolved my issue with "The value violated the integrity constraints for the column.".

The best and fastest option, rather than storing everything in a list and re-opening the file to write it, is in my opinion to re-write the file elsewhere.

with open("yourfile.txt", "r") as file_input:
    with open("newfile.txt", "w") as output: 
        for line in file_input:
            if line.strip("\n") != "nickname_to_delete":
                output.write(line)

That's it! In one loop and one only you can do the same thing. It will be much faster.

There is no php.ini used by the command line. You have to copy the file from ...EasyPHP-<<version>>\apache\php.ini to ...EasyPHP-<<version>>\php\php.ini than edit the one in php directory

It's a surprisingly little-known feature of C++ (as evidenced by the fact that no-one has given this as an answer yet), but it actually has special syntax for value-initializing an array:

new int[10]();

Note that you must use the empty parentheses — you cannot, for example, use (0) or anything else (which is why this is only useful for value initialization).

This is explicitly permitted by ISO C++03 5.3.4[expr.new]/15, which says:

A new-expression that creates an object of type T initializes that object as follows:

...

• If the new-initializer is of the form (), the item is value-initialized (8.5);

and does not restrict the types for which this is allowed, whereas the (expression-list) form is explicitly restricted by further rules in the same section such that it does not allow array types.

If you are into performance, then it is worth using ENUM type. It will probably be faster on big tables, due to the better index performance.

The way of using it (source: http://dev.mysql.com/doc/refman/5.5/en/enum.html):

CREATE TABLE shirts (
    name VARCHAR(40),
    size ENUM('x-small', 'small', 'medium', 'large', 'x-large')
);

But, I always say that explaining the query like this:

EXPLAIN SELECT * FROM shirts WHERE size='medium';

will tell you lots of information about your query and help on building a better table structure. For this end, it is usefull to let phpmyadmin Propose a table table structure - but this is more a long time optimisation possibility, when the table is already filled with lots of data.

It will work as expected.

You should use LoadXml method, not Load:

xmlDoc.LoadXml(myXML); 

Load method is trying to load xml from a file and LoadXml from a string. You could also use XPath:

XmlDocument xmlDoc = new XmlDocument();
xmlDoc.LoadXml(xml);

string xpath = "myDataz/listS/sog";
var nodes = xmlDoc.SelectNodes(xpath);

foreach (XmlNode childrenNode in nodes)
{
    HttpContext.Current.Response.Write(childrenNode.SelectSingleNode("//field1").Value);
} 

The answer to your question is not specific to objective-c, however in different languages, Class methods may be called static methods.

The difference between class methods and instance methods are

Class methods

• Operate on Class variables (they can not access instance variables)
• Do not require an object to be instantiated to be applied
• Sometimes can be a code smell (some people who are new to OOP use as a crutch to do Structured Programming in an OO enviroment)

Instance methods

• Operate on instances variables and class variables
• Must have an instanciated object to operate on

protected void Page_Load(object sender, EventArgs e)
    {
        // prevent user from making operation twice
        btnSave.Attributes.Add("onclick", 
                               "this.disabled=true;" + GetPostBackEventReference(btnSave).ToString() + ";");

        // ... etc. 
    }

I noticed that there is another CSS selector that does the same thing . The syntax is as follows :

[id|="name_id"]

This will select all elements ID which begins with the word enclosed in double quotes.

Lodash is inspired by Underscore.js, but nowadays it is a superior solution. You can make your custom builds, have a higher performance, support AMD and have great extra features. Check this Lodash vs. Underscore.js benchmarks on jsperf and... this awesome post about Lodash:

One of the most useful feature when you work with collections, is the shorthand syntax:

var characters = [
  { 'name': 'barney', 'age': 36, 'blocked': false },
  { 'name': 'fred',   'age': 40, 'blocked': true }
];

// Using "_.filter" callback shorthand
_.filter(characters, { 'age': 36 });

// Using Underscore.js
_.filter(characters, function(character) { return character.age === 36; } );

// ? [{ 'name': 'barney', 'age': 36, 'blocked': false }]

(taken from Lodash documentation)

I got much better solution .

here is my directive , I have injected on object reference in directive and has extend that by adding invoke function in directive code .

app.directive('myDirective', function () {
    return {
        restrict: 'E',
        scope: {
        /*The object that passed from the cntroller*/
        objectToInject: '=',
        },
        templateUrl: 'templates/myTemplate.html',

        link: function ($scope, element, attrs) {
            /*This method will be called whet the 'objectToInject' value is changes*/
            $scope.$watch('objectToInject', function (value) {
                /*Checking if the given value is not undefined*/
                if(value){
                $scope.Obj = value;
                    /*Injecting the Method*/
                    $scope.Obj.invoke = function(){
                        //Do something
                    }
                }    
            });
        }
    };
});

Declaring the directive in the HTML with a parameter:

<my-directive object-to-inject="injectedObject"></ my-directive>

my Controller:

app.controller("myController", ['$scope', function ($scope) {
   // object must be empty initialize,so it can be appended
    $scope.injectedObject = {};

    // now i can directly calling invoke function from here 
     $scope.injectedObject.invoke();
}];

JLRishe's answer is correct, so I simply use this in my event handler:

if (event.target instanceof Element) { /*...*/ }

C:

static void print_buf(const char *title, const unsigned char *buf, size_t buf_len)
{
    size_t i = 0;
    fprintf(stdout, "%s\n", title);
    for(i = 0; i < buf_len; ++i)
    fprintf(stdout, "%02X%s", buf[i],
             ( i + 1 ) % 16 == 0 ? "\r\n" : " " );

}

C++:

void print_bytes(std::ostream& out, const char *title, const unsigned char *data, size_t dataLen, bool format = true) {
    out << title << std::endl;
    out << std::setfill('0');
    for(size_t i = 0; i < dataLen; ++i) {
        out << std::hex << std::setw(2) << (int)data[i];
        if (format) {
            out << (((i + 1) % 16 == 0) ? "\n" : " ");
        }
    }
    out << std::endl;
}

New Python users on Windows often forget to add Python's \Scripts directory to the PATH variable during the installation. I recommend to use the Python launcher and execute pip as a script with the -m switch. Then you can install the wheels for a specific Python version (if more than one are installed) and the Scripts directory doesn't have to be in the PATH. So open the command line, navigate (with the cd command) to the folder where the .whl file is located and enter:

py -3.6 -m pip install your_whl_file.whl

Replace 3.6 by your Python version or just enter -3 if the desired Python version appears first in the PATH. And with an active virtual environment: py -m pip install your_whl_file.whl.

Of course you can also install packages from PyPI in this way, e.g.

py -3.6 -m pip install pygame

So, why didn't anybody suggest just using options that eliminate the parts he doesn't want to process.

On modern Debian you just get your file with:

ls --format=single-column 

Further more, you don't have to pay attention to what directory you are running it in if you use the full directory:

ls --format=single-column /root/dir/starting/point/to/target/dir/

This last command I am using the above and I get the following output:

bot@dev:~/downloaded/Daily# ls --format=single-column /home/bot/downloaded/Daily/*.gz
/home/bot/downloaded/Daily/Liq_DailyManifest_V3_US_20141119_IENT1.txt.gz
/home/bot/downloaded/Daily/Liq_DailyManifest_V3_US_20141120_IENT1.txt.gz
/home/bot/downloaded/Daily/Liq_DailyManifest_V3_US_20141121_IENT1.txt.gz

The answer has been given before. It works for "jdk-8u91-windows-x64.exe" also

1. Unzip with 7-zip, so we get tools.zip

2. Unzip tools.zip to a folder folder_name so we get the contents in the picture

3. In cmd move to the folder folder_name/bin and run the command

   java -version

the output will be

Error occurred during initialization of VM
java/lang/NoClassDefFoundError: java/lang/Object

this indicates that there is something messing. Actually we need to unpack all packages.

4. In cmd move to the folder folder_name and automatically do the unpacking by executing the command

   for /r %x in (*.pack) do .\bin\unpack200 -r "%x" "%~dx%~px%~nx.jar"

5. Do step 3 again, if you get the output bellow, then the JDK is ready to use.

java version "1.8.0_91"
Java(TM) SE Runtime Environment (build 1.8.0_91-b15)
Java HotSpot(TM) 64-Bit Server VM (build 25.91-b15, mixed mode)

Use reqclient: not designed for scripting purpose like request or many other libraries. Reqclient allows in the constructor specify many configurations useful when you need to reuse the same configuration again and again: base URL, headers, auth options, logging options, caching, etc. Also has useful features like query and URL parsing, automatic query encoding and JSON parsing, etc.

The best way to use the library is create a module to export the object pointing to the API and the necessary configurations to connect with:

Module client.js:

let RequestClient = require("reqclient").RequestClient

let client = new RequestClient({
  baseUrl: "https://myapp.com/api/v1",
  cache: true,
  auth: {user: "admin", pass: "secret"}
})

module.exports = client

And in the controllers where you need to consume the API use like this:

let client = require('client')
//let router = ...

router.get('/dashboard', (req, res) => {
  // Simple GET with Promise handling to https://myapp.com/api/v1/reports/clients
  client.get("reports/clients")
    .then(response => {
       console.log("Report for client", response.userId)  // REST responses are parsed as JSON objects
       res.render('clients/dashboard', {title: 'Customer Report', report: response})
    })
    .catch(err => {
      console.error("Ups!", err)
      res.status(400).render('error', {error: err})
    })
})

router.get('/orders', (req, res, next) => {
  // GET with query (https://myapp.com/api/v1/orders?state=open&limit=10)
  client.get({"uri": "orders", "query": {"state": "open", "limit": 10}})
    .then(orders => {
      res.render('clients/orders', {title: 'Customer Orders', orders: orders})
    })
    .catch(err => someErrorHandler(req, res, next))
})

router.delete('/orders', (req, res, next) => {
  // DELETE with params (https://myapp.com/api/v1/orders/1234/A987)
  client.delete({
    "uri": "orders/{client}/{id}",
    "params": {"client": "A987", "id": 1234}
  })
  .then(resp => res.status(204))
  .catch(err => someErrorHandler(req, res, next))
})

reqclient supports many features, but it has some that are not supported by other libraries: OAuth2 integration and logger integration with cURL syntax, and always returns native Promise objects.

read this;-

http://php.net/manual/en/soapclient.call.php

Or

This is a good example, for the SOAP function "__call". However it is deprecated.

<?php
    $wsdl = "http://webservices.tekever.eu/ctt/?wsdl";
    $int_zona = 5;
    $int_peso = 1001;
    $cliente = new SoapClient($wsdl);
    print "<p>Envio Internacional: ";
    $vem = $cliente->__call('CustoEMSInternacional',array($int_zona, $int_peso));
    print $vem;
    print "</p>";
?>

Oh, I have just the thing you need!

$host = "ftp://example.com/dir/";
$savePath = "downloadedFiles";
if($check = isFtpUp($host)){

    echo $ip." -is alive<br />";

    $check = trim($check);
    $files = explode("\n",$check);

    foreach($files as $n=>$file){
        $file = trim($file);
        if($file !== "." || $file !== ".."){
            if(!saveFtpFile($file, $host.$file, $savePath)){
                // downloading failed. possible reason: $file is a folder name.
                // echo "Error downloading file.<br />";
            }else{
                echo "File: ".$file." - saved!<br />";
            }
        }else{
            // do nothing
        }
    }
}else{
    echo $ip." - is down.<br />";
}

and functions isFtpUp and saveFtpFile are as follows:

function isFtpUp($host){
$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $host);
curl_setopt($ch, CURLOPT_USERPWD, "anonymous:[email protected]");
curl_setopt($ch, CURLOPT_FTPLISTONLY, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 3);

$result = curl_exec($ch);

return $result;

}

function saveFtpFile( $targetFile = null, $sourceFile = null, $savePath){

// function settings
set_time_limit(60);
$timeout = 60;
$ftpuser = "anonymous";
$ftppassword = "[email protected]";
$savePath = "downloadedFiles"; // should exist!
$curl = curl_init();
$file = @fopen ($savePath.'/'.$targetFile, 'w');

if(!$file){
    return false;
}

curl_setopt($curl, CURLOPT_URL, $sourceFile);
curl_setopt($curl, CURLOPT_USERPWD, $ftpuser.':'.$ftppassword);

// curl settings

// curl_setopt($curl, CURLOPT_FAILONERROR, 1);
// curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_TIMEOUT, $timeout);
curl_setopt($curl, CURLOPT_FILE, $file);

$result = curl_exec($curl);


if(!$result){
    return false;
}

curl_close($curl);
fclose($file);

return $result;
}

EDIT:

it's a php script. save it as a .php file, put it on your webserver, change $ip to address(need not be ip) of ftp server you want to download files from, create a directory named downloadedFiles on the same directory as this file.

Add a WHERE clause

UPDATE dbo.TestStudents  
SET     LASTNAME =  CASE  
                        WHEN LASTNAME = 'AAA' THEN 'BBB' 
                        WHEN LASTNAME = 'CCC' THEN 'DDD' 
                        WHEN LASTNAME = 'EEE' THEN 'FFF' 
                        ELSE LASTNAME
                    END 
WHERE   LASTNAME IN ('AAA', 'CCC', 'EEE')

I think you should refactor your packages in more convenient hierarchy, so they are out of the base package.

But if you can't do this, try:

<context:component-scan base-package="com.example">
    ...
    <context:exclude-filter type="regex" expression="com\.example\.ignore.*"/>
</context:component-scan>

Here you could find more examples: Using filters to customize scanning

You could use the Directory class

 Directory.GetFiles(path, "*.txt", SearchOption.AllDirectories)

Use join:

>>> sentence = ['this', 'is', 'a', 'sentence']
>>> '-'.join(sentence)
'this-is-a-sentence'
>>> ' '.join(sentence)
'this is a sentence'

You can provide padding to an input like this:

HTML:

<input type=text id=firstname />

CSS:

input {
    width: 250px;
    padding: 5px;
}

however I would also add:

input {
    width: 250px;
    padding: 5px;
    -webkit-box-sizing: border-box; /* Safari/Chrome, other WebKit */
    -moz-box-sizing: border-box;    /* Firefox, other Gecko */
    box-sizing: border-box;         /* Opera/IE 8+ */
}

Box sizing makes the input width stay at 250px rather than increase to 260px due to the padding.

For reference.

I had a related situation, where I specifically needed to set the cursor position to the END of a contenteditable div. I didn't want to use a full fledged library like Rangy, and many solutions were far too heavyweight.

In the end, I came up with this simple jQuery function to set the carat position to the end of a contenteditable div:

$.fn.focusEnd = function() {
    $(this).focus();
    var tmp = $('<span />').appendTo($(this)),
        node = tmp.get(0),
        range = null,
        sel = null;

    if (document.selection) {
        range = document.body.createTextRange();
        range.moveToElementText(node);
        range.select();
    } else if (window.getSelection) {
        range = document.createRange();
        range.selectNode(node);
        sel = window.getSelection();
        sel.removeAllRanges();
        sel.addRange(range);
    }
    tmp.remove();
    return this;
}

The theory is simple: append a span to the end of the editable, select it, and then remove the span - leaving us with a cursor at the end of the div. You could adapt this solution to insert the span wherever you want, thus putting the cursor at a specific spot.

Usage is simple:

$('#editable').focusEnd();

That's it!

For the 64-bit 2020 version

I tried in vain to find the current location of this file for version 2020. When navigating to Help > Edit Custom Properties a new (empty) file is created at appData/Roaming/JetBrains/IntelliJIdea2020.1/idea.properties. There is no /bin directory as some tutorials suggest. However, neither adding the block from the accepted answer to this file nor adding the same file to /bin resulted in an update to my configuration.

I finally discovered that a reference to the same property exists in appData/Roaming/JetBrains/IntelliJIdea2020.1/idea64.exe.vmoptions. It looks like this:

-Didea.max.intellisense.filesize=3470

I changed it to this, which should be adequate for my needs:

-Didea.max.intellisense.filesize=9999

This strikes me as a bug in this version where the behavior of the menu item doesn't reflect what's needed, but it may also be the case that my particular setup is somehow different than stock. I do have PyCharm and the JDK installed.

Easiest way: search for javac.exe in windows search bar. Then copy and paste the entire folder name and add it into the environmental variables path in advanced system settings.

Sadly there are no operation-assignment operators in VBA.

(Addition-assignment += are available in VB.Net)

Pointless workaround;

Sub Inc(ByRef i As Integer)
   i = i + 1  
End Sub
...
Static value As Integer
inc value
inc value

Is this what you need?

DataTable myDataTable = new DataTable();
List<int> myList = new List<int>();
foreach (DataRow row in myDataTable.Rows)
{
    myList.Add((int)row[0]);
}

You may approach this differently; omit the use of the :empty pseudo-class and utilize input events to detect a significant value in the <input> field and style it accordingly:

var inputs = document.getElementsByTagName('input');_x000D_
_x000D_
for (var i = 0; i < inputs.length; i++) {_x000D_
  var input = inputs[i];_x000D_
  input.addEventListener('input', function() {_x000D_
    var bg = this.value ? 'green' : 'red';_x000D_
    this.style.backgroundColor = bg;_x000D_
  });_x000D_
}

body {_x000D_
  padding: 40px;_x000D_
}_x000D_
#inputList li {_x000D_
  list-style-type: none;_x000D_
  padding-bottom: 1.5em;_x000D_
}_x000D_
#inputList li input,_x000D_
#inputList li label {_x000D_
  float: left;_x000D_
  width: 10em;_x000D_
}_x000D_
#inputList li input {_x000D_
  color: white;_x000D_
  background-color: red;_x000D_
}_x000D_
#inputList li label {_x000D_
  text-align: right;_x000D_
  padding-right: 1em;_x000D_
}

<ul id="inputList">_x000D_
  <li>_x000D_
    <label for="username">Enter User Name:</label>_x000D_
    <input type="text" id="username" />_x000D_
  </li>_x000D_
  <li>_x000D_
    <label for="password">Enter Password:</label>_x000D_
    <input type="password" id="password" />_x000D_
  </li>_x000D_
</ul>

This will delete all content from current line to end of the file. This is very useful when you're dealing with test vector generation or stripping.

In two words:

attr_accessor is getter, setter method. whereas attr_accessible is to say that particular attribute is accessible or not. that's it.

I wish to add we should use Strong parameter instead of attr_accessible to protect from mass asignment.

Cheers!

Every thread accessing a volatile field will read its current value before continuing, instead of (potentially) using a cached value.

Only member variable can be volatile or transient.

You can use Explicit wait or Fluent Wait

Example of Explicit Wait -

WebDriverWait wait = new WebDriverWait(WebDriverRefrence,20);
WebElement aboutMe;
aboutMe= wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("about_me")));     

Example of Fluent Wait -

Wait<WebDriver> wait = new FluentWait<WebDriver>(driver)                            
.withTimeout(20, TimeUnit.SECONDS)          
.pollingEvery(5, TimeUnit.SECONDS)          
.ignoring(NoSuchElementException.class);    

  WebElement aboutMe= wait.until(new Function<WebDriver, WebElement>() {       
public WebElement apply(WebDriver driver) { 
return driver.findElement(By.id("about_me"));     
 }  
});

You just need to a add the path of your PHP file. In case you are using wamp or have not installed it on the C drive.

This also could be easiest way to add items in ListBox.

for (int i = 0; i < MyList.Count; i++)
{
        listBox1.Items.Add(MyList.ElementAt(i));
}

Further improvisation of this code can add items at runtime.

I posted an answer to this already when someone else asked the same question (see How to bring back "Browser mode" in IE11?).

Read my answer there for a fuller explaination, but in short:

• They removed it deliberately, because compat mode is not actually really very good for testing compatibility.

• If you really want to test for compatibility with any given version of IE, you need to test in a real copy of that IE version. MS provide free VMs on http://modern.ie/ for you to use for this purpose.

• The only way to get compat mode in IE11 is to set the X-UA-Compatible header. When you have this and the site defaults to compat mode, you will be able to set the mode in dev tools, but only between edge or the specified compat mode; other modes will still not be available.

<?php if(!class_exists('PDO2')) {
    class PDO2 {
        private static $_instance;
        public static function getInstance() {
            if (!isset(self::$_instance)) {
                try {
                    self::$_instance = new PDO(
                        'mysql:host=***;dbname=***',
                        '***',
                        '***',
                        array(
                            PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES utf8mb4 COLLATE utf8mb4_general_ci",
                            PDO::ATTR_ERRMODE            => PDO::ERRMODE_EXCEPTION
                        )
                    );
                } catch (PDOException $e) {
                    throw new PDOException($e->getMessage(), (int) $e->getCode());

}
$req = PDO2::getInstance()->prepare('SELECT * FROM table');
$req->execute();
$count = $req->rowCount();
$results = $req->fetchAll(PDO::FETCH_ASSOC);
$req->closeCursor();
// Do other requests maybe
// And close connection
PDO2::closeInstance();
// print output

Full example, with custom class PDO2.

In the other question I suggested autoexnt. That is also possible in this situation. Just set the service to run manually (ie not automatic at startup). When you want to run your batch, modify the autoexnt.bat file to call the batch file you want, and start the autoexnt service.

The batchfile to start this, can look like this (untested):

echo call c:\path\to\batch.cmd %* > c:\windows\system32\autoexnt.bat
net start autoexnt

Note that batch files started this way run as the system user, which means you do not have access to network shares automatically. But you can use net use to connect to a remote server.

You have to download the Windows 2003 Resource Kit to get it. The Resource Kit can also be installed on other versions of windows, like Windows XP.

According to @Data description you can use:

All generated getters and setters will be public. To override the access level, annotate the field or class with an explicit @Setter and/or @Getter annotation. You can also use this annotation (by combining it with AccessLevel.NONE) to suppress generating a getter and/or setter altogether.

This worked for me:

HTML:

<div>

  WHATEVER YOU WANT

  <a href="YOUR LINK HERE">
    <span class="span-link"></span>
  </a>

</div>

CSS:

.span-link {
  position:absolute;
  width:100%;
  height:100%;
  top:0;
  left: 0;
  z-index: 9999;
}

This adds an invisible element (the span), which covers your entire div, and is above your whole div on the z-index, so when someone clicks on that div, the click is essentially intercepted by your invisible "span" layer, which is linked.

Note: If you're already using z-indexes for other elements, just make sure the value of this z-index is higher than anything you want it to rest "on top" of.

You didn't mention if you are using Excel 2003 or 2007, but you may run into an issue with the # of rows in Excel 2003 being capped at 65,536. If you are using 2007, the limit is 1,048,576.

Also, can I ask what your end goal is for your analysis? If you need to perform many statistical calculations on your data, I would recommend moving out of the Excel environment into something that is more directly suited for data manipulation and analysis, such as R.

There are a variety of options for connecting R to Excel, including

1. RExcel
2. RODBC
3. Other options in the R manual

Regardless of what you choose to use to move data in/out of R, the code to change from wide to long format is pretty trivial. I enjoy the melt() function from the reshape package. That code would look like:

library(reshape)
#Fake data, 4 columns, 20k rows
df <- data.frame(foo = rnorm(20000)
    , bar = rlnorm(20000)
    , fee = rnorm(20000)
    , fie = rlnorm(20000)
)
#Create new object with 1 column, 80k rows
df.m <- melt(df)

From there, you can perform any number of statistical or graphing operations. If you use the RExcel plugin above, you can fire all of this up and run it within Excel itself. The R community is very active and can help address any and all questions you may encounter.

Good luck!

Here's another version, and it's arguably a bit simpler.

multipetal <- function(df, n) {
    varname <- paste("petal", n, sep=".")
    df<-mutate_(df, .dots=setNames(paste0("Petal.Width*",n), varname))
    df
}

for(i in 2:5) {
    iris <- multipetal(df=iris, n=i)
}

In Visual Studio you can directly embed access to a file resource via the Resources tab of the Project properties ("Analytics" in this example).

The resulting file can then be accessed as a byte array by

byte[] jsonSecrets = GoogleAnalyticsExtractor.Properties.Resources.client_secrets_reporter;

Should you need it as a stream, then ( from https://stackoverflow.com/a/4736185/432976 )

Stream stream = new MemoryStream(jsonSecrets)

List<String> l = new ArrayList<String>(listOfTopicAuthors);

The other answers are right, but when you're dealing with interfaces you cannot use typeof or instanceof because interfaces don't get compiled to javascript.

Instead you can use a typecast + function check typeguard to check your variable:

interface Car {
    drive(): void;
    honkTheHorn(): void;
}

interface Bike {
    drive(): void;
    ringTheBell(): void;
}

function start(vehicle: Bike | Car ) {
    vehicle.drive();

    // typecast and check if the function exists
    if ((<Bike>vehicle).ringTheBell) {
        const bike = (<Bike>vehicle);
        bike.ringTheBell();
    } else {
        const car = (<Car>vehicle);
        car.honkTheHorn();
    }
}

And this is the compiled JavaScript in ES2017:

function start(vehicle) {
    vehicle.drive();
    if (vehicle.ringTheBell) {
        const bike = vehicle;
        bike.ringTheBell();
    }
    else {
        const car = vehicle;
        car.honkTheHorn();
    }
}

I had my files at the correct places, and just removing <scope>test</scope> from the JUnit dependency entry solved the problem (I am using JUnit 4.12). I believe that with the test scope the dependency was just being ignored during the compilation phase. Now everything is working even when I call mvn test.

I think the project you are looking for is: https://github.com/sarxos/webcam-capture (I'm the author)

There is an example working exactly as you've described - after it's run, the window appear where, after you press "Start" button, you can see live image from webcam device and save it to file after you click on "Snapshot" (source code available, please note that FPS counter in the corner can be disabled):

The project is portable (WinXP, Win7, Win8, Linux, Mac, Raspberry Pi) and does not require any additional software to be installed on the PC.

API is really nice and easy to learn. Example how to capture single image and save it to PNG file:

Webcam webcam = Webcam.getDefault();
webcam.open();
ImageIO.write(webcam.getImage(), "PNG", new File("test.png"));

Keep the original bootstrap with 12 columns, do not customize it. The only modification you need to make is some css after the original bootstrap responsive css, like this:

The following code has been tested for Bootstrap 2.3.2:

<style type="text/css">
/* start of modification for 5 columns */
@media (min-width: 768px){
    .fivecolumns .span2 {
        width: 18.297872340425532%;
        *width: 18.2234042553191494%;
    }
}
@media (min-width: 1200px) {
    .fivecolumns .span2 {
        width: 17.9487179487179488%;
        *width: 17.87424986361156592%;
    }
}
@media (min-width: 768px) and (max-width: 979px) {
    .fivecolumns .span2 {
        width: 17.79005524861878448%;
        *width: 17.7155871635124022%;
    }
}
/* end of modification for 5 columns */
</style>

And the html:

<div class="row-fluid fivecolumns">
    <div class="span2">
        <h2>Heading</h2>
        <p>Donec id elit non mi porta gravida at eget metus. Fusce dapibus, tellus ac cursus commodo, tortor mauris condimentum nibh, ut fermentum massa justo sit amet risus. Etiam porta sem malesuada magna mollis euismod. Donec sed odio dui. </p>
        <p><a class="btn" href="#">View details &raquo;</a></p>
    </div>
    <div class="span2">
        <h2>Heading</h2>
        <p>Donec id elit non mi porta gravida at eget metus. Fusce dapibus, tellus ac cursus commodo, tortor mauris condimentum nibh, ut fermentum massa justo sit amet risus. Etiam porta sem malesuada magna mollis euismod. Donec sed odio dui. </p>
        <p><a class="btn" href="#">View details &raquo;</a></p>
    </div>
    <div class="span2">
        <h2>Heading</h2>
        <p>Donec sed odio dui. Cras justo odio, dapibus ac facilisis in, egestas eget quam. Vestibulum id ligula porta felis euismod semper. Fusce dapibus, tellus ac cursus commodo, tortor mauris condimentum nibh, ut fermentum massa justo sit amet risus.</p>
        <p><a class="btn" href="#">View details &raquo;</a></p>
    </div>
    <div class="span2">
        <h2>Heading</h2>
        <p>Donec sed odio dui. Cras justo odio, dapibus ac facilisis in, egestas eget quam. Vestibulum id ligula porta felis euismod semper. Fusce dapibus, tellus ac cursus commodo, tortor mauris condimentum nibh, ut fermentum massa justo sit amet risus.</p>
        <p><a class="btn" href="#">View details &raquo;</a></p>
    </div>
    <div class="span2">
        <h2>Heading</h2>
        <p>Donec sed odio dui. Cras justo odio, dapibus ac facilisis in, egestas eget quam. Vestibulum id ligula porta felis euismod semper. Fusce dapibus, tellus ac cursus commodo, tortor mauris condimentum nibh, ut fermentum massa justo sit amet risus.</p>
        <p><a class="btn" href="#">View details &raquo;</a></p>
    </div>
</div>

Note: Even though the span2 times 5 doesn't equal 12 columns, you get the idea :)

A working example can be found here http://jsfiddle.net/v3Uy5/6/

Easy. Use .shape.

>>> nparray.shape
(5, 6) #Returns a tuple of array dimensions.

this query return last record for every Form_id:

    SELECT m1.*
     FROM messages m1 LEFT JOIN messages m2
     ON (m1.Form_id = m2.Form_id AND m1.id < m2.id)
     WHERE m2.id IS NULL;

Yes, using the indexOf() method on the string class. See the API documentation for this method
