As in this answer Custom HTTP Header for a specific file you can use <File> to enable CORS for a single file with this code:

<Files "index.php">
  Header set Access-Control-Allow-Origin "*"
  Header set Access-Control-Allow-Methods: "GET,POST,OPTIONS,DELETE,PUT"
</Files>

To use the least amount of space you should use a CHAR field constrained to 'Y' or 'N'. Oracle doesn't support BOOLEAN, BIT, or TINYINT data types, so CHAR's one byte is as small as you can get.

I think it would be a lot more productive to use a TextWriter, in this case a StreamWriter to write to the MemoryStream. After that, as other have said, you need to "rewind" the MemoryStream using something like stringAsStream.Position = 0L;.

stringAsStream = new MemoryStream();

// create stream writer with UTF-16 (Unicode) encoding to write to the memory stream
using(StreamWriter sWriter = new StreamWriter(stringAsStream, UnicodeEncoding.Unicode))
{
  sWriter.Write("Lorem ipsum.");
}
stringAsStream.Position = 0L; // rewind

Note that:

StreamWriter defaults to using an instance of UTF8Encoding unless specified otherwise. This instance of UTF8Encoding is constructed without a byte order mark (BOM)

Also, you don't have to create a new UnicodeEncoding() usually, since there's already one as a static member of the class for you to use in convenient utf-8, utf-16, and utf-32 flavors.

And then, finally (as others have said) you're trying to convert the bytes directly to chars, which they are not. If I had a memory stream and knew it was a string, I'd use a TextReader to get the string back from the bytes. It seems "dangerous" to me to mess around with the raw bytes.

You can have an iframe inside the modal markup and give the src attribute of it as the link to your pdf. On click of the link you can show this modal markup.

Use this single line.

This questions is already answered here. Just put height: 100% in both the div and the container td.

you can use ref to call the function of the child component from the parent

Functional Component Solution

in functional component, you have to use useImperativeHandle for getting ref into a child like below

import React, { forwardRef, useRef, useImperativeHandle } from 'react';
export default function ParentFunction() {
    const childRef = useRef();
    return (
        <div className="container">
            <div>
                Parent Component
            </div>
            <button
                onClick={() => { childRef.current.showAlert() }}
            >
            Call Function
            </button>
            <Child ref={childRef}/>
        </div>
    )
}
const Child = forwardRef((props, ref) => {
    useImperativeHandle(
        ref,
        () => ({
            showAlert() {
                alert("Child Function Called")
            }
        }),
    )
    return (
       <div>Child Component</div>
    )
})

Class Component Solution

Child.js

import s from './Child.css';

class Child extends Component {
 getAlert() {
    alert('clicked');
 }
 render() {
  return (
    <h1>Hello</h1>
  );
 }
}

export default Child;

Parent.js

class Parent extends Component {
 render() {
  onClick() {
    this.refs.child.getAlert();
  }
  return (
    <div>
      <Child ref="child" />
      <button onClick={this.onClick}>Click</button>
    </div>
  );
 }
}

according to the latest version of MySQL (phpMyAdmin), add a correct INDEX while choosing primary key. for example: id[int] INDEX 0 ,if id is your primary key and at the first index. Or,

For your problem try this one

CREATE TABLE `table`.`users` (
    `id` INT(11) NOT NULL AUTO_INCREMENT,
    `username` VARCHAR(50) NOT NULL,
    `password` VARCHAR(50) NOT NULL,
    `dir` VARCHAR(100) NOT NULL,
    PRIMARY KEY (`id`)
) ENGINE = MyISAM;

you can use the following SQL statement to check the given column on table was indexed or not

select  a.table_schema, a.table_name, a.column_name, index_name
from    information_schema.columns a
join    information_schema.tables  b on a.table_schema  = b.table_schema and
                                    a.table_name = b.table_name and 
                                    b.table_type = 'BASE TABLE'
left join (
 select     concat(x.name, '/', y.name) full_path_schema, y.name index_name
 FROM   information_schema.INNODB_SYS_TABLES  as x
 JOIN   information_schema.INNODB_SYS_INDEXES as y on x.TABLE_ID = y.TABLE_ID
 WHERE  x.name = 'your_schema'
 and    y.name = 'your_column') d on concat(a.table_schema, '/', a.table_name, '/', a.column_name) = d.full_path_schema
where   a.table_schema = 'your_schema'
and     a.column_name  = 'your_column'
order by a.table_schema, a.table_name;

since the joins are against INNODB_SYS_*, so the match indexes only came from INNODB tables only

Try this:

            DataTable dt = new DataTable();
            int sum = 0;
            foreach (DataRow dr in dt.Rows)
            {
                foreach (DataColumn dc in dt.Columns)
                {
                    sum += (int)dr[dc];
                }
            } 

It basically occours when you return from a loop you can only return from function

I modified Zack's answer since I wanted spaces and interpolation but not newlines and used:

%W[
  It's a nice day "#{name}"
  for a walk!
].join(' ')

where name = 'fred' this produces It's a nice day "fred" for a walk!

if you want to get the data in the entire row, you can use this combination below

tableModel.getDataVector().elementAt(jTable.getSelectedRow());

Where "tableModel" is the model for the table that can be accessed like so

(DefaultTableModel) jTable.getModel();

this will return the entire row data.

I hope this helps somebody

The replaceAll method is attempting to match the String literal [] which does not exist within the String try replacing these items separately.

String str = "[Chrissman-@1]";
str = str.replaceAll("\\[", "").replaceAll("\\]","");

I think that this may be easier to read and is definitely the standard for use in C#:

while(true)
{
   //Do My Loop Stuff
}

from flask import Flask, jsonify, request
app = Flask(__name__)

@app.route('/service', methods=['POST'])
def service():
    data = json.loads(request.data)
    text = data.get("text",None)
    if text is None:
        return jsonify({"message":"text not found"})
    else:
        return jsonify(data)

if __name__ == '__main__':
    app.run(host= '0.0.0.0',debug=True)

This code also works:

this.formGroup.controls.nameOfcontrol.value

Below worked for me,

-name: Upload html app directory to Deployment host
 copy: src=/var/lib/jenkins/workspace/Demoapp/html dest=/var/www/ directory_mode=yes

This may be what you want. Settings -> Appearance & Behavior -> System Settings > Project Opening > Default Directory

1. Open 'Preferences'
2. Select System Settings -> Project Opening
3. Set 'Default Directory' where you want.

It worked for me. I tried Android Studio 3.5.

You can achieve similar results with pig/hive queries. The main difference lies within approach to understanding/writing/creating queries.

Pig tends to create a flow of data: small steps where in each you do some processing
Hive gives you SQL-like language to operate on your data, so transformation from RDBMS is much easier (Pig can be easier for someone who had not earlier experience with SQL)

It is also worth noting, that for Hive you can nice interface to work with this data (Beeswax for HUE, or Hive web interface), and it also gives you metastore for information about your data (schema, etc) which is useful as a central information about your data.

I use both Hive and Pig, for different queries (I use that one where I can write query faster/easier, I do it this way mostly ad-hoc queries) - they can use the same data as an input. But currently I'm doing much of my work through Beeswax.

While @Andre is correct that there are issues with pseudo elements and their support, especially in older (IE) browsers, that support is improving all the time.

As for your question of, are there any issues, I'd say I've not really seen any, although the syntax for the pseudo-element can be a bit tricky, especially when first sussing it out. So:

div#top-level
  declarations: ...
  div.inside
    declarations: ...
    &:first-child
      declarations: ...

which compiles as one would expect:

div#top-level{
  declarations... }
div#top-level div.inside {
  declarations... }
div#top-level div.inside:first-child {
  declarations... }

I haven't seen any documentation on any of this, save for the statement that "sass can do everything that css can do." As always, with Haml and SASS the indentation is everything.

Do you have any open SQL Server Management Studio windows that are connected to this DB?

Put it in single user mode, and then try again.

I used requests-mock for writing tests for separate module:

# module.py
import requests

class A():

    def get_response(self, url):
        response = requests.get(url)
        return response.text

And the tests:

# tests.py
import requests_mock
import unittest

from module import A


class TestAPI(unittest.TestCase):

    @requests_mock.mock()
    def test_get_response(self, m):
        a = A()
        m.get('http://aurl.com', text='a response')
        self.assertEqual(a.get_response('http://aurl.com'), 'a response')
        m.get('http://burl.com', text='b response')
        self.assertEqual(a.get_response('http://burl.com'), 'b response')
        m.get('http://curl.com', text='c response')
        self.assertEqual(a.get_response('http://curl.com'), 'c response')

if __name__ == '__main__':
    unittest.main()

The pros and cons are pretty much identical.It depends on whether you want this or not.

Be careful, if MySQL timezone differs from your system time (for instance PHP), comparing the time or printing to the user will involve some tinkering.

Just so you know, I am using Visual Studio 2013 and have had the same problem until I used the Project Properties to switch to 3.5 framework and back to 4.5. This for some reason registered the .dll properly and I could use the System.Web.Extensions.

ls -l --block-size=M will give you a long format listing (needed to actually see the file size) and round file sizes up to the nearest MiB.

If you want MB (10^6 bytes) rather than MiB (2^20 bytes) units, use --block-size=MB instead.

If you don't want the M suffix attached to the file size, you can use something like --block-size=1M. Thanks Stéphane Chazelas for suggesting this.

This is described in the man page for ls; man ls and search for SIZE. It allows for units other than MB/MiB as well, and from the looks of it (I didn't try that) arbitrary block sizes as well (so you could see the file size as number of 412-byte blocks, if you want to).

Note that the --block-size parameter is a GNU extension on top of the Open Group's ls, so this may not work if you don't have a GNU userland (which most Linux installations do). The ls from GNU coreutils 8.5 does support --block-size as described above.

I have recently encountered this problem. Here are the steps to resolve

1. Check the servers section in the settings.xml file.Is username and password correct?

<servers>_x000D_
  <server>_x000D_
    <id>serverId</id>_x000D_
    <username>username</username>_x000D_
    <password>password</password>_x000D_
  </server>_x000D_
</servers>

2. Check the repository section in the pom.xml file.The id of the server tag should be the same as the id of the repository tag.

<repositories>_x000D_
 <repository>_x000D_
   <id>serverId</id>  _x000D_
   <url>http://maven.aliyun.com/nexus/content/groups/public/</url>_x000D_
 </repository>_x000D_
</repositories>

3. If the repository tag is not configured in the pom.xml file, look in the settings.xml file.

<profiles>_x000D_
 <profile>_x000D_
   <repositories>_x000D_
     <repository>_x000D_
      <id>serverId</id>_x000D_
      <name>aliyun</name>_x000D_
      <url>http://maven.aliyun.com/nexus/content/groups/public/</url>_x000D_
     </repository>_x000D_
   </repositories>_x000D_
 </profile>_x000D_
</profiles>

Note that you should ensure that the id of the server tag should be the same as the id of the repository tag.

Ljava.lang.String;@ is returned where you used string arrays as strings. Employee.getSelectCancel() does not seem to return a String[]

As Luke Smith says, image load is a mess. It's not reliable on all browsers. This fact has given me great pain. A cached image will not fire the event at all in some browsers, so those who said "image load is better than setTimeout" are wrong.

Luke Smith's solution is here.

And there is an interesting discussion about how this mess might be handled in jQuery 1.4.

I have found that it's pretty reliable to set the width to 0, then wait for the "complete" property to go true and the width property to come in greater than zero. You should watch for errors, too.

If you just need the current date, without time, another option is:

DateTime.now().withTimeAtStartOfDay()

The best equivalent is using ContextCompat.getColor and ResourcesCompat.getColor . I made some extension functions for quick migration:

@ColorInt
fun Context.getColorCompat(@ColorRes colorRes: Int) = ContextCompat.getColor(this, colorRes)

@ColorInt
fun Fragment.getColorCompat(@ColorRes colorRes: Int) = activity!!.getColorCompat(colorRes)

@ColorInt
fun Resources.getColorCompat(@ColorRes colorRes: Int) = ResourcesCompat.getColor(this, colorRes, null)

Because the main thread exits.

Put a sleep in the main thread.

cout << "Hello";
sleep(1);

return 0;

The POSIX standard does not specify what happens when the main thread exits.
But in most implementations this will cause all spawned threads to die.

So in the main thread you should wait for the thread to die before you exit. In this case the simplest solution is just to sleep and give the other thread a chance to execute. In real code you would use pthread_join();

#include <iostream>
#include <pthread.h>
using namespace std;

#if defined(__cplusplus)
extern "C"
#endif
void *print_message(void*)
{
    cout << "Threading\n";
}



int main() 
{
    pthread_t t1;

    pthread_create(&t1, NULL, &print_message, NULL);
    cout << "Hello";

    void* result;
    pthread_join(t1,&result);

    return 0;
}

Use align-items: flex-start on the container, or align-self: flex-start on the flex items.

No need for display: inline-flex.

An initial setting of a flex container is align-items: stretch. This means that flex items will expand to cover the full length of the container along the cross axis.

The align-self property does the same thing as align-items, except that align-self applies to flex items while align-items applies to the flex container.

By default, align-self inherits the value of align-items.

Since your container is flex-direction: column, the cross axis is horizontal, and align-items: stretch is expanding the child element's width as much as it can.

You can override the default with align-items: flex-start on the container (which is inherited by all flex items) or align-self: flex-start on the item (which is confined to the single item).

Learn more about flex alignment along the cross axis here:

• How does flex-wrap work with align-self, align-items and align-content?

First add the import line:

from pyspark.sql.functions import min, max

To find the min value of age in the dataframe:

df.agg(min("age")).show()

+--------+
|min(age)|
+--------+
|      29|
+--------+

To find the max value of age in the dataframe:

df.agg(max("age")).show()

+--------+
|max(age)|
+--------+
|      77|
+--------+

You could raise SystemExit(0) instead of going to all the trouble to import sys; sys.exit(0).

Here's another suggestion:

public interface Service<T> {
   T execute();
}

using this simple interface you can pass arguments via constructor in the concrete service classes:

public class FooService implements Service<String> {

    private final String input1;
    private final int input2;

    public FooService(String input1, int input2) {
       this.input1 = input1;
       this.input2 = input2;
    }

    @Override
    public String execute() {
        return String.format("'%s%d'", input1, input2);
    }
}

This:

    print "\n"

is printing out two \n characters -- the one you tell it to, and the one that Python prints out at the end of any line which doesn't end with a , like you use in print a,. Simply use

    print

instead.

This error just means that myapp.views.home is not something that can be called, like a function. It is a string in fact. While your solution works in django 1.9, nevertheless it throws a warning saying this will deprecate from version 1.10 onwards, which is exactly what has happened. The previous solution by @Alasdair imports the necessary view functions into the script through either from myapp import views as myapp_views or from myapp.views import home, contact

For me the problem was bad/missing config values for the Plesk server running the whole thing. I just followed the directions here: http://davidseah.com/blog/2007/04/separate-php-error-logs-for-multiple-domains-with-plesk/

You can configure PHP to have a separate error log file for each VirtualHost definition. The trick is knowing exactly how to set it up, because you can’t touch the configuration directly without breaking Plesk. Every domain name on your (dv) has its own directory in /var/www/vhosts. A typical directory has the following top level directories:

cgi-bin/
conf/
error_docs/
httpdocs/
httpsdocs/
...and so on

You’ll want to create a vhost.conf file in the domain directory’s conf/ folder with the following lines:

php_value error_log /path/to/error_log
php_flag display_errors off
php_value error_reporting 6143
php_flag log_errors on

Change the first value to match your actual installation (I used /tmp/phperrors.log). After you’re done editing the vhost.conf file, test the configuration from the console with:

apachectl configtest
…or if you don’t have apachectl (as Plesk 8.6 doesn’t seem to)…

/etc/init.d/httpd configtest

And finally tell Plesk that you’ve made this change.

/usr/local/psa/admin/bin/websrvmng -a

If they are in the same controller class, it would be:

foreach ( $characters as $character) {
    $num += $this->getFactorial($index) * $index;
    $index ++;
}

Otherwise you need to create a new instance of the class, and call the method, ie:

$controller = new MyController();
foreach ( $characters as $character) {
    $num += $controller->getFactorial($index) * $index;
    $index ++;
}

You need an assignment operator so that:

arrayOfAs[i] = A(3);

works as it should.

I don't know JavaScript and I just started to learn PHP, so what helped for me from all those responses was:

1. Create inedx.php and insert:

<iframe name="email" style=""></iframe>
<form action="email.php" method="post" target="email">
<input type="email" name="email" >
<input type="submit" name="Submit" value="Submit">
</form>

2. Create email.php and insert this code to check if you are getting the data (you should see it on index.php in the iframe):

    <?php
    if (isset($_POST['Submit'])){
    $email = $_POST['email'];
    echo $email;
    }
    ?>

3. If everything is ok, change the code on email.php to:

    <?php
    if (isset($_POST['Submit'])){
    $to = $_POST['email'];
    $subject = "Test email";
    $message = "Test message";
    $headers = "From: [email protected] \r\n";
    $headers .= "Reply-To: [email protected] \r\n";
    $headers .= "MIME-Version: 1.0\r\n";
    $headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n";
    
    mail($to, $subject, $message, $headers);
    }
    ?>

Hope this helps for all other rookies like me :)

The standard streams have a boolalpha flag that determines what gets displayed -- when it's false, they'll display as 0 and 1. When it's true, they'll display as false and true.

There's also an std::boolalpha manipulator to set the flag, so this:

#include <iostream>
#include <iomanip>

int main() {
    std::cout<<false<<"\n";
    std::cout << std::boolalpha;   
    std::cout<<false<<"\n";
    return 0;
}

...produces output like:

0
false

For what it's worth, the actual word produced when boolalpha is set to true is localized--that is, <locale> has a num_put category that handles numeric conversions, so if you imbue a stream with the right locale, it can/will print out true and false as they're represented in that locale. For example,

#include <iostream>
#include <iomanip>
#include <locale>

int main() {
    std::cout.imbue(std::locale("fr"));

    std::cout << false << "\n";
    std::cout << std::boolalpha;
    std::cout << false << "\n";
    return 0;
}

...and at least in theory (assuming your compiler/standard library accept "fr" as an identifier for "French") it might print out faux instead of false. I should add, however, that real support for this is uneven at best--even the Dinkumware/Microsoft library (usually quite good in this respect) prints false for every language I've checked.

The names that get used are defined in a numpunct facet though, so if you really want them to print out correctly for particular language, you can create a numpunct facet to do that. For example, one that (I believe) is at least reasonably accurate for French would look like this:

#include <array>
#include <string>
#include <locale>
#include <ios>
#include <iostream>

class my_fr : public std::numpunct< char > {
protected:
    char do_decimal_point() const { return ','; }
    char do_thousands_sep() const { return '.'; }
    std::string do_grouping() const { return "\3"; }
    std::string do_truename() const { return "vrai";  }
    std::string do_falsename() const { return "faux"; }
};

int main() {
    std::cout.imbue(std::locale(std::locale(), new my_fr));

    std::cout << false << "\n";
    std::cout << std::boolalpha;
    std::cout << false << "\n";
    return 0;
}

And the result is (as you'd probably expect):

0
faux

According to Joshua Bloch (Effective Java), you should use private constructor which always throws exception. That will finally discourage user to create instance of util class.

Marking class abstract is not recommended because is abstract suggests reader that class is designed for inheritance.

From a SQLServerCentral.Com article by Ken Powers:

The Semicolon

The semicolon character is a statement terminator. It is a part of the ANSI SQL-92 standard, but was never used within Transact-SQL. Indeed, it was possible to code T-SQL for years without ever encountering a semicolon.

Usage

There are two situations in which you must use the semicolon. The first situation is where you use a Common Table Expression (CTE), and the CTE is not the first statement in the batch. The second is where you issue a Service Broker statement and the Service Broker statement is not the first statement in the batch.

You can now link to an external site using React Link by providing an object to to with the pathname key:

<Link to={ { pathname: '//example.zendesk.com/hc/en-us/articles/123456789-Privacy-Policies' } } >

If you find that you need to use JS to generate the link in a callback, you can use window.location.replace() or window.location.assign().

Over using window.location.replace(), as other good answers suggest, try using window.location.assign().

window.location.replace() will replace the location history without preserving the current page.

window.location.assign() will transition to the url specified, but will save the previous page in the browser history, allowing proper back-button functionality.

https://developer.mozilla.org/en-US/docs/Web/API/Location/replace https://developer.mozilla.org/en-US/docs/Web/API/Location/assign

Also, if you are using a window.location = url method as mentioned in other answers, I highly suggest switching to window.location.href = url. There is a heavy argument about it, where many users seem to adamantly want to revert the newer object type window.location to its original implementation as string merely because they can (and they egregiously attack anyone who says otherwise), but you could theoretically interrupt other library functionality accessing the window.location object.

Check out this convo. It's terrible. Javascript: Setting location.href versus location

The problem with your code is :

     String  show[]= {rs4.getString(1)};
     String actuate[]={rs4.getString(2)};

This will create a new array every time your loop (an not append as you might be assuming) and hence in the end you will have only one element per array.

Here is one more way to solve this :

    StringBuilder sids = new StringBuilder ();
    StringBuilder lids = new StringBuilder ();

    while (rs4.next()) {
        sids.append(rs4.getString(1)).append(" ");
        lids.append(rs4.getString(2)).append(" ");
    }

    String show[] = sids.toString().split(" "); 
    String actuate[] = lids.toString().split(" ");

These arrays will have all the required element.

Dependencies

These are the packages that your package needs to run, so they will be installed when people run

 npm install PACKAGE-NAME

An example would be if you used jQuery in your project. If someone doesn't have jQuery installed, then it wouldn't work. To save as a dependency, use

 npm install --save

These are the dependencies that you use in development, but isn't needed when people are using it, so when people run npm install, it won't install them since the are not necessary. For example, if you use mocha to test, people don't need mocha to run, so npm install doesn't install it. To save as a dev dependency, use

npm install PACKAGE --save-dev

Peer Dependencies

These can be used if you want to create and publish your own library so that it can be used as a dependency. For example, if you want your package to be used as a dependency in another project, then these will also be installed when someone installs the project which has your project as a dependency. Most of the time you won't use peer dependencies.

Here's this exact same question elsewhere, that includes a more robust equals, hash that maerics alludes to:

http://groups.google.com/group/comp.lang.java.help/browse_thread/thread/f8b63fc645c1b487/1d94be050cfc249b

That discussion goes on to mirror the maerics vs ColinD approaches of "should I re-use a class Tuple with an unspecific name, or make a new class with specific names each time I encounter this situation". Years ago I was in the latter camp; I've evolved into supporting the former.

Storing "Simple" Repeating Patterns

For my PHP/MySQL based calendar, I wanted to store repeating/recurring event information as efficiently as possibly. I didn't want to have a large number of rows, and I wanted to easily lookup all events that would take place on a specific date.

The method below is great at storing repeating information that occurs at regular intervals, such as every day, every n days, every week, every month every year, etc etc. This includes every Tuesday and Thursday type patterns as well, because they are stored separately as every week starting on a Tuesday and every week starting on a Thursday.

Assuming I have two tables, one called events like this:

ID    NAME
1     Sample Event
2     Another Event

And a table called events_meta like this:

ID    event_id      meta_key           meta_value
1     1             repeat_start       1299132000
2     1             repeat_interval_1  432000

With repeat_start being a date with no time as a unix timestamp, and repeat_interval an amount in seconds between intervals (432000 is 5 days).

repeat_interval_1 goes with repeat_start of the ID 1. So if I have an event that repeats every Tuesday and every Thursday, the repeat_interval would be 604800 (7 days), and there would be 2 repeat_starts and 2 repeat_intervals. The table would look like this:

ID    event_id      meta_key           meta_value
1     1             repeat_start       1298959200 -- This is for the Tuesday repeat
2     1             repeat_interval_1  604800
3     1             repeat_start       1299132000 -- This is for the Thursday repeat
4     1             repeat_interval_3  604800
5     2             repeat_start       1299132000
6     2             repeat_interval_5  1          -- Using 1 as a value gives us an event that only happens once

Then, if you have a calendar that loops through every day, grabbing the events for the day it's at, the query would look like this:

SELECT EV.*
FROM `events` EV
RIGHT JOIN `events_meta` EM1 ON EM1.`event_id` = EV.`id`
RIGHT JOIN `events_meta` EM2 ON EM2.`meta_key` = CONCAT( 'repeat_interval_', EM1.`id` )
WHERE EM1.meta_key = 'repeat_start'
    AND (
        ( CASE ( 1299132000 - EM1.`meta_value` )
            WHEN 0
              THEN 1
            ELSE ( 1299132000 - EM1.`meta_value` )
          END
        ) / EM2.`meta_value`
    ) = 1
LIMIT 0 , 30

Replacing {current_timestamp} with the unix timestamp for the current date (Minus the time, so the hour, minute and second values would be set to 0).

Hopefully this will help somebody else too!

Storing "Complex" Repeating Patterns

This method is better suited for storing complex patterns such as

Event A repeats every month on the 3rd of the month starting on March 3, 2011

or

Event A repeats Friday of the 2nd week of the month starting on March 11, 2011

I'd recommend combining this with the above system for the most flexibility. The tables for this should like like:

ID    NAME
1     Sample Event
2     Another Event

And a table called events_meta like this:

ID    event_id      meta_key           meta_value
1     1             repeat_start       1299132000 -- March 3rd, 2011
2     1             repeat_year_1      *
3     1             repeat_month_1     *
4     1             repeat_week_im_1   2
5     1             repeat_weekday_1   6

repeat_week_im represents the week of the current month, which could be between 1 and 5 potentially. repeat_weekday in the day of the week, 1-7.

Now assuming you are looping through the days/weeks to create a month view in your calendar, you could compose a query like this:

SELECT EV . *
FROM `events` AS EV
JOIN `events_meta` EM1 ON EM1.event_id = EV.id
AND EM1.meta_key = 'repeat_start'
LEFT JOIN `events_meta` EM2 ON EM2.meta_key = CONCAT( 'repeat_year_', EM1.id )
LEFT JOIN `events_meta` EM3 ON EM3.meta_key = CONCAT( 'repeat_month_', EM1.id )
LEFT JOIN `events_meta` EM4 ON EM4.meta_key = CONCAT( 'repeat_week_im_', EM1.id )
LEFT JOIN `events_meta` EM5 ON EM5.meta_key = CONCAT( 'repeat_weekday_', EM1.id )
WHERE (
  EM2.meta_value =2011
  OR EM2.meta_value = '*'
)
AND (
  EM3.meta_value =4
  OR EM3.meta_value = '*'
)
AND (
  EM4.meta_value =2
  OR EM4.meta_value = '*'
)
AND (
  EM5.meta_value =6
  OR EM5.meta_value = '*'
)
AND EM1.meta_value >= {current_timestamp}
LIMIT 0 , 30

This combined with the above method could be combined to cover most repeating/recurring event patterns. If I've missed anything please leave a comment.

You come across this issue when your function name and one of the id names in the file are same. just make sure all your id names in the file are unique.

You first have to tell Gnuplot to use a style that uses points, e.g. with points or with linespoints. Try for example:

plot sin(x) with points

Output:

Now try:

plot sin(x) with points pointtype 5

Output:

You may also want to look at the output from the test command which shows you the capabilities of the current terminal. Here are the capabilities for my pngairo terminal:

This is an servlet code which contain a string variable a. the value for a is getting from an html page with form. then set the variable into the request object. then pass it to jsp using forward and requestdispatcher methods.

String a=req.getParameter("username");
req.setAttribute("name", a);
RequestDispatcher rd=req.getRequestDispatcher("/login.jsp");
rd.forward(req, resp);

in jsp follow these steps shown below in the program

<%String name=(String)request.getAttribute("name");
out.print("your name"+name);%>

Definitely regex:

string CleanPhone(string phone)
{
    Regex digitsOnly = new Regex(@"[^\d]");   
    return digitsOnly.Replace(phone, "");
}

or within a class to avoid re-creating the regex all the time:

private static Regex digitsOnly = new Regex(@"[^\d]");   

public static string CleanPhone(string phone)
{
    return digitsOnly.Replace(phone, "");
}

Depending on your real-world inputs, you may want some additional logic there to do things like strip out leading 1's (for long distance) or anything trailing an x or X (for extensions).

You could use PhoneGap.

This has the benefit of being a cross-platform solution. Be warned though that you may need to pay subscription fees. The simplest solution is to just embed a WebView as detailed in @Enigma's answer.

ReSharper offers a Generate Constructor tool where you can select any field/properties that you want initialized. I use the Alt + Ins hot-key to access this.

I would use inspect.currentframe().f_back.f_code.co_name. Its use hasn't been covered in any of the prior answers which are mainly of one of three types:

• Some prior answers use inspect.stack but it's known to be too slow.
• Some prior answers use sys._getframe which is an internal private function given its leading underscore, and so its use is implicitly discouraged.
• One prior answer uses inspect.getouterframes(inspect.currentframe(), 2)[1][3] but it's entirely unclear what [1][3] is accessing.

import inspect
from types import FrameType
from typing import cast


def caller_name() -> str:
    """Return the calling function's name."""
    # Ref: https://stackoverflow.com/a/57712700/
    return cast(FrameType, cast(FrameType, inspect.currentframe()).f_back).f_code.co_name


if __name__ == '__main__':
    def _test_caller_name() -> None:
        assert caller_name() == '_test_caller_name'
    _test_caller_name()

Note that cast(FrameType, frame) is used to satisfy mypy.

Acknowlegement: comment by 1313e for an answer.

Use the following code:

foreach (string line in File.ReadAllLines(fileName))

This was a HUGE difference in reading performance.

It comes at the cost of memory consumption, but totally worth it!

Update 17/07/27: As this is the most-voted answer, I should update this to include current information locally (with links to the references).

From the spec ^[1]:

The aside element represents a section of a page that consists of content that is tangentially related to the content of the parenting sectioning content, and which could be considered separate from that content. Such sections are often represented as sidebars in printed typography.

Great! Exactly what we're looking for. In addition, it is best to check on <section> as well.

The section element represents a generic section of a document or application. A section, in this context, is a thematic grouping of content. Each section should be identified, typically by including a heading (h1-h6 element) as a child of the section element.

...

A general rule is that the section element is appropriate only if the element’s contents would be listed explicitly in the document’s outline.

Excellent. Just what we're looking for. As opposed to <article> ^[2] which is for "self-contained" content, <section> allows for related content that isn't stand-alone, or generic enough for a <div> element.

As such, the spec seems to suggest that using Option 1, <aside> with <section> children is best practice.

a is defined locally in the function, and can't be used outside the function. If you want to return a char array from the function, you'll need to allocate it dynamically:

char *a = malloc(1000);

And at some point call free on the returned pointer.

You should also see a warning at this line: char b = "blah";: you're trying to assign a string literal to a char.

Probably you didn't add your room class to child RoomDatabase child class in @Database(entities = {your_classes})

You could use this to pick all li elements without class:

$('ul#list li:not([class])')

It shows how an algorithm scales based on input size.

O(n²): known as Quadratic complexity

• 1 item: 1 operations
• 10 items: 100 operations
• 100 items: 10,000 operations

Notice that the number of items increases by a factor of 10, but the time increases by a factor of 10². Basically, n=10 and so O(n²) gives us the scaling factor n² which is 10².

O(n): known as Linear complexity

• 1 item: 1 second
• 10 items: 10 seconds
• 100 items: 100 seconds

This time the number of items increases by a factor of 10, and so does the time. n=10 and so O(n)'s scaling factor is 10.

O(1): known as Constant complexity

• 1 item: 1 operations
• 10 items: 1 operations
• 100 items: 1 operations

The number of items is still increasing by a factor of 10, but the scaling factor of O(1) is always 1.

O(log n): known as Logarithmic complexity

• 1 item: 1 operations
• 10 items: 2 operations
• 100 items: 3 operations
• 1000 items: 4 operations
• 10,000 items: 5 operations

The number of computations is only increased by a log of the input value. So in this case, assuming each computation takes 1 second, the log of the input n is the time required, hence log n.

That's the gist of it. They reduce the maths down so it might not be exactly n² or whatever they say it is, but that'll be the dominating factor in the scaling.

You only have to get the view of activity that carry this fragment and this could only happen when your fragment is already created

override the onViewCreated() method inside your fragment and enjoy its magic :) ..

@Override
public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);
    Button button = (Button) view.findViewById(R.id.YOURBUTTONID);
    button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
         //place your action here
         }
    });

Hope this could help you ;

For Python versions prior to 2.6, use the string formatting operator %:

filename = "ME%d.txt" % i

For 2.6 and later, use the str.format() method:

filename = "ME{0}.txt".format(i)

Though the first example still works in 2.6, the second one is preferred.

If you have more than 10 files to name this way, you might want to add leading zeros so that the files are ordered correctly in directory listings:

filename = "ME%02d.txt" % i
filename = "ME{0:02d}.txt".format(i)

This will produce file names like ME00.txt to ME99.txt. For more digits, replace the 2 in the examples with a higher number (eg, ME{0:03d}.txt).

From the error, I infer that referenceElement is a dictionary (see repro below). A dictionary cannot be hashed and therefore cannot be used as a key to another dictionary (or itself for that matter!).

>>> d1, d2 = {}, {}
>>> d1[d2] = 1
Traceback (most recent call last):
  File "<input>", line 1, in <module>
TypeError: unhashable type: 'dict'

You probably meant either for element in referenceElement.keys() or for element in json['referenceElement'].keys(). With more context on what types json and referenceElement are and what they contain, we will be able to better help you if neither solution works.

If you want downloads number for each customer, use:

select ssn
     , sum(time)
  from downloads
 group by ssn

If you want just one record -- for a customer with highest number of downloads -- use:

select *
  from (
        select ssn
             , sum(time)
          from downloads
         group by ssn
         order by sum(time) desc
       )
 where rownum = 1

However if you want to see all customers with the same number of downloads, which share the highest position, use:

select *
  from (
        select ssn
             , sum(time)
             , dense_rank() over (order by sum(time) desc) r
          from downloads
         group by ssn
       )
 where r = 1

As others have said both are valid and will do the trick. I'm not 100% convinced that they are identical though. If you have some style cascading going on then they could in theory produce different results since they are effectively overriding different values.

For example. If you set "border: none;" and then later on have two different styles that override the border width and style then one will do something and the other will not.

In the following example on both IE and firefox the first two test divs come out with no border. The second two however are different with the first div in the second block being plain and the second div in the second block having a medium width dashed border.

So though they are both valid you may need to keep an eye on your styles if they do much cascading and such like I think.

<html>
<head>
<style>
div {border: 1px solid black; margin: 1em;}
.zerotest div {border: 0;}
.nonetest div {border: none;}

div.setwidth {border-width: 3px;}
div.setstyle {border-style: dashed;}

</style>
</head>
<body>

<div class="zerotest">
<div class="setwidth">
"Border: 0" and "border-width: 3px"
</div>
<div class="setstyle">
"Border: 0" and "border-style: dashed"
</div>
</div>

<div class="nonetest">
<div class="setwidth">
"Border: none" and "border-width: 3px"
</div>
<div class="setstyle">
"Border: none" and "border-style: dashed"
</div>
</div>

</body>
</html>

You can technically use colons and periods in id/name attributes, but I would strongly suggest avoiding both.

In CSS (and several JavaScript libraries like jQuery), both the period and the colon have special meaning and you will run into problems if you're not careful. Periods are class selectors and colons are pseudo-selectors (eg., ":hover" for an element when the mouse is over it).

If you give an element the id "my.cool:thing", your CSS selector will look like this:

#my.cool:thing { ... /* some rules */ ... }

Which is really saying, "the element with an id of 'my', a class of 'cool' and the 'thing' pseudo-selector" in CSS-speak.

Stick to A-Z of any case, numbers, underscores and hyphens. And as said above, make sure your ids are unique.

That should be your first concern.

If you're using Python3, then install:

python3 -m pip install --user xlsxwriter

This will run pip with the appropriate version of Python3. If you run bare pip3 and have many versions of Python install, it will still fail leading to more confusion.

The --user flag will allow to install as a regular user and no require root.

typeperf gives me issues when it randomly doesn't work on some computers (Error: No valid counters.) or if the account has insufficient rights. Otherwise, here is a way to extract just the value from its output. It still needs rounding though:

@for /f "delims=, tokens=2" %p in ('typeperf "\Processor(_Total)\% Processor Time" -sc 3 ^| find ":"') do @echo %~p%

Powershell has two cmdlets to get the percent utilization for all CPUs: Get-Counter (preferred) or Get-WmiObject:

Powershell "Get-Counter '\Processor(*)\% Processor Time' | Select -Expand Countersamples | Select InstanceName, CookedValue"

Or,

Powershell "Get-WmiObject Win32_PerfFormattedData_PerfOS_Processor | Select Name, PercentProcessorTime"

To get the overall CPU load with formatted output exactly like the question:

Powershell "[string][int](Get-Counter '\Processor(*)\% Processor Time').Countersamples[0].CookedValue + '%'"

Or,

 Powershell "gwmi Win32_PerfFormattedData_PerfOS_Processor | Select -First 1 | %{'{0}%' -f $_.PercentProcessorTime}"

I have a Samsung Galaxy Tab 2 7.0 with Android 4.1.1. Apparently it does NOT sync to ntp. I loaded an app that says my tablet is 20 seconds off of ntp, but it can't set it unless I root the device.

the articles posted by Ricky are very good, but unfortunately they don't answer your question.

To solve your problem you should try this piece of code:

ExeConfigurationFileMap configMap = new ExeConfigurationFileMap();
configMap.ExeConfigFilename = @"d:\test\justAConfigFile.config.whateverYouLikeExtension";
Configuration config = ConfigurationManager.OpenMappedExeConfiguration(configMap, ConfigurationUserLevel.None);

If need to access a value within the config you can use the index operator:

config.AppSettings.Settings["test"].Value;

There are some misconceptions here.

Frequencies above 500 can be represented in an FFT result of length 1000. Unfortunately these frequencies are all folded together and mixed into the first 500 FFT result bins. So normally you don't want to feed an FFT a signal containing any frequencies at or above half the sampling rate, as the FFT won't care and will just mix the high frequencies together with the low ones (aliasing) making the result pretty much useless. That's why data should be low-pass filtered before being sampled and fed to an FFT.

The FFT returns amplitudes without frequencies because the frequencies depend, not just on the length of the FFT, but also on the sample rate of the data, which isn't part of the FFT itself or it's input. You can feed the same length FFT data at any sample rate, as thus get any range of frequencies out of it.

The reason the result plots ends at 500 is that, for any real data input, the frequencies above half the length of the FFT are just mirrored repeats (complex conjugated) of the data in the first half. Since they are duplicates, most people just ignore them. Why plot duplicates? The FFT calculates the other half of the result for people who feed the FFT complex data (with both real and imaginary components), which does create two different halves.

lvalue means "left value" -- it should be assignable. You cannot change the value of text since it is an array, not a pointer.

Either declare it as char pointer (in this case it's better to declare it as const char*):

const char *text;
if(number == 2) 
    text = "awesome"; 
else 
    text = "you fail";

Or use strcpy:

char text[60];
if(number == 2) 
    strcpy(text, "awesome"); 
else 
    strcpy(text, "you fail");

The message is fairly self-explanatory; your working directory should not be the NumPy source directory when you invoke Python; NumPy should be installed and your working directory should be anything but the directory where it lives.

This won't fix branches that already have the code you don't want in them (see below for how to do that), but if they had pulled some-branch and now want it to be clean (and not "ahead" of origin/some-branch) then you simply:

git checkout some-branch   # where some-branch can be replaced by any other branch
git branch base-branch -D  # where base-branch is the one with the squashed commits
git checkout -b base-branch origin/base-branch  # recreating branch with correct commits

Note: You can combine these all by putting && between them

Note2: Florian mentioned this in a comment, but who reads comments when looking for answers?

Note3: If you have contaminated branches, you can create new ones based off the new "dumb branch" and just cherry-pick commits over.

Ex:

git checkout feature-old  # some branch with the extra commits
git log                   # gives commits (write down the id of the ones you want)
git checkout base-branch  # after you have already cleaned your local copy of it as above
git checkout -b feature-new # make a new branch for your feature
git cherry-pick asdfasd   # where asdfasd is one of the commit ids you want
# repeat previous step for each commit id
git branch feature-old -D # delete the old branch

Now feature-new is your branch without the extra (possibly bad) commits!

As per recent version. You need to go advanced settings. In this section you will find the un-publish button.

The quick and dirty way to check what string you need it to look at the generated .resources files.

Your .resources are generated in the resources projects obj/Debug directory. (if not right click on .resx file in solution explorer and hit 'Run Custom Tool' to generate the .resources files)

Navigate to this directory and have a look at the filenames. You should see a file ending in XYZ.resources. Copy that filename and remove the trailing .resources and that is the file you should be loading.

For example in my obj/Bin directory I have the file:

MyLocalisation.Properties.Resources.resources

If the resource files are in the same Class library/Application I would use the following C#

ResourceManager RM = new ResourceManager("MyLocalisation.Properties.Resources", Assembly.GetExecutingAssembly());

However, as it sounds like you are using the resources file from a separate Class library/Application you probably want

Assembly localisationAssembly = Assembly.Load("MyLocalisation");
ResourceManager RM =  new ResourceManager("MyLocalisation.Properties.Resources", localisationAssembly);

I found the answer I was looking for. The thing to use here is the construct of

\left \middle \right

For example, in this case, two possible solutions are:

$\left( {\frac{a_1}{a_2}} \middle/ {\frac{b_1}{b_2}} \right) $

Or, in case the brackets are not necessary:

$\left. {\frac{a_1}{a_2}} \middle/ {\frac{b_1}{b_2}} \right. $

The font may exist with different names, and not at all on some systems, so you need to use different variations and fallback to get the closest possible look on all systems:

font-family: "Comic Sans MS", "Comic Sans", cursive;

Be careful what you use this font for, though. Many consider it as ugly and overused, so it should not be use for something that should look professional.

I am a beginner in coding. This is my attempt to answer the questions. Used Python3.7 version without importing any libraries.

This code extracts and returns a decimal number from a string made of sets of characters separated by blanks (words).

Attention: In case there are more than one number, it returns the last value.

line = input ('Please enter your string ')
for word in line.split():
    try:
        a=float(word)
        print (a)
    except ValueError:
        pass

If you're using WPF there is a LoadCompleted event.

If it's Windows.Forms, the DocumentCompleted event should be the correct one. If the page you're loading has frames, your WebBrowser control will fire the DocumentCompleted event for each frame (see here for more details). I would suggest checking the IsBusy property each time the event is fired and if it is false then your page is fully done loading.

You can synchronize your code over the class. That would be simplest.

   public class Test  
    {  
       private static int count = 0;  
       private static final Object lock= new Object();    
       public synchronized void foo() 
      {  
          synchronized(Test.class)
         {  
             count++;  
         }  
      }  
    }

Hope you find this answer useful.

Sqliteman is my current preference: It uses QT, so it's cross-platform. Since I develop on Windows, Linux and OS X, it helps to have the same tools available on each.

I also tried SQLite Admin (Windows, so irrelevant to the question anyway) for a while, but it seems unmaintained these days, and has the most annoying hotkeys of any application I've ever used - Ctrl-S clears the current query, with no hope of undo.

In my case I solved recreating the database. I made some changes in a model and launching Update-Database in Package Manager Console I got the following Error:

"The ALTER TABLE statement conflicted with the FOREIGN KEY constraint "FK_dbo.Activities_dbo.Projects_ProjectId". The conflict occurred in database "TrackEmAllContext-20190530144302", table "dbo.Projects", column 'Id'."

Just like ASP.NET variant, except put the hidden input with the same name before the actual checkbox (of the same name). Only last values will be sent. This way if a box is checked then its name and value "on" is sent, whereas if it's unchecked then the name of the corresponding hidden input and whatever value you might like to give it will be sent. In the end you will get the $_POST array to read, with all checked and unchecked elements in it, "on" and "false" values, no duplicate keys. Easy to process in PHP.

If you already have the figure object use:

f.set_figheight(15)
f.set_figwidth(15)

But if you use the .subplots() command (as in the examples you're showing) to create a new figure you can also use:

f, axs = plt.subplots(2,2,figsize=(15,15))

$str = "Is your name O\'vins?";

// Outputs: Is your name O'vins? echo stripslashes($str);

<location path="ControllerName/ActionName">
    <system.web>
        <httpRuntime executionTimeout="1000"/>
    </system.web>
</location>

Probably it is better to set such values in web.config instead of controller. Hardcoding of configurable options is considered harmful.

take look at this snippet from my project

 $("input[type="submit"]", "#letter-form").on("click",
        function(e) {
             e.preventDefault();


$.post($("#letter-form").attr('action'), $("#letter-form").serialize(),
                 function(response) {// your response from form submit
                    if (response.result === 'Redirect') {
                        window.location = response.url;
                    } else {
                        Message(response.saveChangesResult, response.operation, response.data);
                    }
});
$(this).attr('disabled', 'disabled'); //this is what you want

so just disabled the button after your operation executed

$(this).attr('disabled', 'disabled');

I use the _var naming for member variables of my classes. There are 2 main reasons I do:

1) It helps me keep track of class variables and local function variables when I'm reading my code later.

2) It helps in Intellisense (or other code-completion system) when I'm looking for a class variable. Just knowing the first character is helpful in filtering through the list of available variables and methods.

NEQ is usually used for numbers and == is typically used for string comparison.

I cannot find any documentation that mentions a specific and equivalent inequality operand for string comparison (in place of NEQ). The solution using IF NOT == seems the most sound approach. I can't immediately think of a circumstance in which the evaluation of operations in a batch file would cause an issue or unexpected behavior when applying the IF NOT == comparison method to strings.

I wish I could offer insight into how the two functions behave differently on a lower level - would disassembling separate batch files (that use NEQ and IF NOT ==) offer any clues in terms of which (unofficially documented) native API calls conhost.exe is utilizing?

org.apache.commons.lang3.StringEscapeUtils from commons-lang3 is marked deprecated now. You can use org.apache.commons.text.StringEscapeUtils#unescapeJava(String) instead. It requires an additional Maven dependency:

        <dependency>
            <groupId>org.apache.commons</groupId>
            <artifactId>commons-text</artifactId>
            <version>1.4</version>
        </dependency>

and seems to handle some more special cases, it e.g. unescapes:

• escaped backslashes, single and double quotes
• escaped octal and unicode values
• \\b, \\n, \\t, \\f, \\r

Without VBA...

If you can use a helper column, you can use the MATCH function to test if a value in one column exists in another column (or in another column on another worksheet). It will return an Error if there is no match

To simply identify duplicates, use a helper column

Assume data in Sheet1, Column A, and another list in Sheet2, Column A. In your helper column, row 1, place the following formula:

=If(IsError(Match(A1, 'Sheet2'!A:A,False)),"","Duplicate")

Drag/copy this forumla down, and it should identify the duplicates.

To highlight cells, use conditional formatting:

With some tinkering, you can use this MATCH function in a Conditional Formatting rule which would highlight duplicate values. I would probably do this instead of using a helper column, although the helper column is a great way to "see" results before you make the conditional formatting rule.

Something like:

=NOT(ISERROR(MATCH(A1, 'Sheet2'!A:A,FALSE)))

For Excel 2007 and prior, you cannot use conditional formatting rules that reference other worksheets. In this case, use the helper column and set your formatting rule in column A like:

=B1="Duplicate"

This screenshot is from the 2010 UI, but the same rule should work in 2007/2003 Excel.

Pretty simple:

<script type="text/javascript">
    (function($) {
        $(function() {
            $("#accordion > div").accordion({ header: "h3", collapsible: true });
        })
    })(jQuery);
</script>

<div id="accordion">
    <div>
        <h3><a href="#">First</a></h3>
        <div>Lorem ipsum dolor sit amet. Lorem ipsum dolor sit amet. Lorem ipsum dolor sit amet.</div>
    </div>
    <div>
        <h3><a href="#">Second</a></h3>
        <div>Phasellus mattis tincidunt nibh.</div>
    </div>
    <div>
        <h3><a href="#">Third</a></h3>
        <div>Nam dui erat, auctor a, dignissim quis.</div>
    </div>
</div>

You aren't building your formula right.

Worksheets("EmployeeCosts").Range("B" & var1a).Formula =  "=SUM(H5:H" & var1a & ")"

This does the same as the following lines do:

Dim myFormula As String
myFormula = "=SUM(H5:H"
myFormula = myFormula & var1a
myformula = myformula & ")"

which is what you are trying to do.

Also, you want to have the = at the beginning of the formala.

In my case what removed this message was (After updating everything) deleting the emulator and creating a new one. Manually updating the adb didn't solved this for. Nor updating via the Android studio Gui. In my case it seems that since the emulator was created with "old" components it keep showing the message. I had three emulators, just deleted them all and created a new one. For my surprise when it started the message was no more.

Cannot tell if performance is better or not. The message just didn't came up. Also I have everything updated to the latest (emulators and sdk).

bool contains = pricePublicList.Any(p => p.Size == 200);

Put it into a ScrollViewer.

You have two possibilities (for an IPv4 address) :

• a varchar(15), if your want to store the IP address as a string
  • 192.128.0.15 for instance
• an integer (4 bytes), if you convert the IP address to an integer
  • 3229614095 for the IP I used before

The second solution will require less space in the database, and is probably a better choice, even if it implies a bit of manipulations when storing and retrieving the data (converting it from/to a string).

About those manipulations, see the ip2long() and long2ip() functions, on the PHP-side, or inet_aton() and inet_ntoa() on the MySQL-side.

This snippet will handle more than two checkboxes in case you decide to expand the form.

$("input[type=text]").keyup(function(){
    var count = 0, attr = "disabled", $sub = $("#submit"), $inputs = $("input[type=text]");  
    $inputs.each(function(){
        count += ($.trim($(this).val())) ? 1:0;
    });
    (count >= $inputs.length ) ? $sub.removeAttr(attr):$sub.attr(attr,attr);       
});

Gmail requires port 465, and also it's the code from phpmailer :)

Although @Remus Rusanu's is already an excelent answer, in case one is looking forward a better insight on SQL Server's Deadlock causes and trace strategies, I would suggest you to read Brad McGehee's How to Track Down Deadlocks Using SQL Server 2005 Profiler

If you need dynamic collection, you should consider using one of java.util.Collection implementations that fits your problem. E.g. java.util.List.

You can implement the interface with a class, then you can deal with initializing the members in the constructor:

class IXClass implements IX {
    a: string;
    b: any;
    c: AnotherType;

    constructor(obj: IX);
    constructor(a: string, b: any, c: AnotherType);
    constructor() {
        if (arguments.length == 1) {
            this.a = arguments[0].a;
            this.b = arguments[0].b;
            this.c = arguments[0].c;
        } else {
            this.a = arguments[0];
            this.b = arguments[1];
            this.c = arguments[2];
        }
    }
}

Another approach is to use a factory function:

function ixFactory(a: string, b: any, c: AnotherType): IX {
    return {
        a: a,
        b: b,
        c: c
    }
}

Then you can simply:

var ix: IX = null;
...

ix = new IXClass(...);
// or
ix = ixFactory(...);

For Angular 8 or posterior @ViewChild have an additional parameter called opts, which have two properties: read and static, read is optional. You can use it like so:

// ...
@ViewChild('mydiv', { static: false }) public mydiv: ElementRef;

constructor() {
// ...

<div #mydiv></div>

NOTE: Static: false is not required anymore in Angular 9. (just { static: true } when you are going to use that variable inside ngOnInit)

Rails doesnt like the using of ^ and $ for some security reasons , probably its better to use \A and \z to set the beginning and the end of the string

As mentioned in other answers, JavaScript regexes have no support for Unicode character classes. However, there is a library that does provide this: Steven Levithan's excellent XRegExp and its Unicode plug-in.

pygame is not distributed via pip. See this link which provides windows binaries ready for installation.

1. Install python
2. Make sure you have python on your PATH
3. Download the appropriate wheel from this link
4. Install pip using this tutorial

5. Finally, use these commands to install pygame wheel with pip

   • Python 2 (usually called pip)

     • pip install file.whl

   • Python 3 (usually called pip3)

     • pip3 install file.whl

Another tutorial for installing pygame for windows can be found here. Although the instructions are for 64bit windows, it can still be applied to 32bit

Yes, this can be done via javascript feature detection ( or browser detection , e.g. Modernizr ) . Then, use yepnope.js to load required resources ( JS and/or CSS )

Html5 also recommend to use <html lang="es-ES"> The small letter lang tag only specifies: language code The large letter specifies: country code

This is really useful for ie.Chrome, when the browser is proposing to translate web content(ie google translate)

Another option to fine-tune the line height of an icon is by using a percentage of the vertical-align property. Usually, 0% is a the bottom, and 100% at the top, but one could use negative values or more than a hundred to create interesting effects.

.my-element i.fa {
    vertical-align: 100%; // top
    vertical-align: 50%; // middle
    vertical-align: 0%; // bottom
}

Use this in your Textbox Keydown event.

Private Sub TextBox1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles TextBox1.KeyDown
    'you can enter decimal "if nonNumberEntered(e, TextBox1, True) then" 
    'otherwise just numbers "if nonNumberEntered(e, TextBox1) then"
    If nonNumberEntered(e, TextBox1, True) Then
        e.SuppressKeyPress = True
    End If
    If e.KeyCode = Keys.Enter Then
        'put your code here
    End If

End Sub

Copy this function in any module inside your vb.net project.

Public Function nonNumberEntered(ByVal e As System.Windows.Forms.KeyEventArgs, _
                          ByVal ob As TextBox, _
                          Optional ByVal decim As Boolean = False) As Boolean
    nonNumberEntered = False

    If decim Then
        ' Determine whether the keystroke is a number from the top of the keyboard.
        If e.KeyCode < Keys.D0 OrElse e.KeyCode > Keys.D9 Then
            ' Determine whether the keystroke is a number from the keypad.
            If e.KeyCode < Keys.NumPad0 OrElse e.KeyCode > Keys.NumPad9 Then
                If e.KeyCode <> Keys.Decimal And e.KeyCode <> Keys.OemPeriod Then
                    If e.KeyCode <> Keys.Divide And e.KeyCode <> Keys.OemQuestion Then
                        ' Determine whether the keystroke is a backspace.
                        If e.KeyCode <> Keys.Back And e.KeyCode <> Keys.Delete _
                        And e.KeyCode <> Keys.Left And e.KeyCode <> Keys.Right Then
                            ' A non-numerical keystroke was pressed. 
                            nonNumberEntered = True
                        End If
                    ElseIf ob.Text.Contains("/") Or ob.Text.Length = 0 Then
                        nonNumberEntered = True
                    End If
                ElseIf ob.Text.Contains(".") Or ob.Text.Length = 0 Then
                    nonNumberEntered = True
                End If
            End If
        End If
    Else
        ' Determine whether the keystroke is a number from the top of the keyboard.
        If e.KeyCode < Keys.D0 OrElse e.KeyCode > Keys.D9 Then
            ' Determine whether the keystroke is a number from the keypad.
            If e.KeyCode < Keys.NumPad0 OrElse e.KeyCode > Keys.NumPad9 Then
                ' Determine whether the keystroke is a backspace.
                If e.KeyCode <> Keys.Back And e.KeyCode <> Keys.Delete _
                    And e.KeyCode <> Keys.Left And e.KeyCode <> Keys.Right Then
                    ' A non-numerical keystroke was pressed. 
                    nonNumberEntered = True
                End If
            End If
        End If
    End If

    'If shift key was pressed, it's not a number.
    If Control.ModifierKeys = Keys.Shift Then
        nonNumberEntered = True
    End If

End Function

This will allow numbers like 2/4 or numbers like 3.5 to be entered in your textbox if using decim "nonNumberEntered(e,Textbox1, True)".

Allows only numbers to be entered in textbox if using "nonNumberEntered(e,Textbox1, False)" or "nonNumberEntered(e,Textbox1)".

Edit: added text.

There is a paper about this: http://www.cs.kent.edu/~jmaletic/papers/ICPC2010-CamelCaseUnderScoreClouds.pdf

TL;DR It says that snake_case is more readable than camelCase. That's why modern languages use (or should use) snake wherever they can.

I had a similar problems, till I got it working. Below is the full listing of the integration:

1. Generate public/private keys pair: ssh-keygen -t rsa

2. Copy the public key (~/.ssh/id_rsa.pub) and paste it in Bitbucket SSH keys, in user’s account management console:

3. Copy the private key (~/.ssh/id_rsa) to new user (or even existing one) with private key credentials, in this case, username will not make a difference, so username can be anything:

4. run this command to test if you can get access to Bitbucket account: ssh -T [email protected]

5. OPTIONAL: Now, you can use your git to to copy repo to your desk without passwjord git clone [email protected]:username/repo_name.git

6. Now you can enable Bitbucket hooks for Jenkins push notifications and automatic builds, you will do that in 2 steps:

   1. Add an authentication token inside the job/project you configure, it can be anything:

   2. In Bitbucket hooks: choose jenkins hooks, and fill the fields as below:

Where:

**End point**: username:usertoken@jenkins_domain_or_ip
**Project name**: is the name of job you created on Jenkins
**Token**: Is the authorization token you added in the above steps in your Jenkins' job/project 

Recommendation: I usually add the usertoken as the authorization Token (in both Jenkins Auth Token job configuration and Bitbucket hooks), making them one variable to ease things on myself.

modifying the proxy value under

I'm not sure how you might do this with Node, but the general idea would be to send an HTTP HEAD request to the URL you're interested in.

HEAD

Asks for the response identical to the one that would correspond to a GET request, but without the response body. This is useful for retrieving meta-information written in response headers, without having to transport the entire content.

Something like this, based it on this question:

var cli = require('cli');
var http = require('http');
var url = require('url');

cli.parse();

cli.main(function(args, opts) {
        this.debug(args[0]);

        var siteUrl = url.parse(args[0]);
        var site = http.createClient(80, siteUrl.host);
        console.log(siteUrl);

        var request = site.request('HEAD', siteUrl.pathname, {'host' : siteUrl.host})
        request.end();

        request.on('response', function(response) {
                response.setEncoding('utf8');
                console.log('STATUS: ' + response.statusCode);
                response.on('data', function(chunk) {
                        console.log("DATA: " + chunk);
                });
        });
});

This answer is pretty similar to Oz.'s, using <chrono> for C++ -- I didn't grab it from Oz. though...

I picked up the original snippet at the bottom of this page, and slightly modified it to be a complete console app. I love using this lil' ol' thing. It's fantastic if you do a lot of scripting and need a reliable tool in Windows to get the epoch in actual milliseconds without resorting to using VB, or some less modern, less reader-friendly code.

#include <chrono>
#include <iostream>

int main() {
    unsigned __int64 now = std::chrono::duration_cast<std::chrono::milliseconds>(std::chrono::system_clock::now().time_since_epoch()).count();
    std::cout << now << std::endl;
    return 0;
}

git commit -am "message"

is an easy way to tell git to delete files you have deleted, but I generally don't recommend such catch-all workflows. Git commits should in best practice be fairly atomic and only affect a few files.

git add .
git commit -m "message"

is an easy way to add all files new or modified. Also, the catch-all qualification applies. The above commands will not delete files deleted without the git rm command.

git add app
git commit -m "message"

is an easy way to add all files to the index from a single dir, in this case the app dir.

I am a little late to party but you may want to consider using GetAwaiter.GetResult() to run your async code in sync context but as paralled as below;

 Parallel.ForEach(ids, i =>
{
    ICustomerRepo repo = new CustomerRepo();
    // Run this in thread which Parallel library occupied.
    var cust = repo.GetCustomer(i).GetAwaiter().GetResult();
    customers.Add(cust);
});

The following modification of Rômulo's answer works for me on Python 2 and 3 (2.7.12 and 3.6.1):

import os
import subprocess

process = subprocess.Popen(command, stdout=subprocess.PIPE)
while True:
  line = process.stdout.readline()
  if line != '':
    os.write(1, line)
  else:
    break

If you are looking to reduce the size using coding itself, you can follow this code in php.

<?php 
function compress($source, $destination, $quality) {

    $info = getimagesize($source);

    if ($info['mime'] == 'image/jpeg') 
        $image = imagecreatefromjpeg($source);

    elseif ($info['mime'] == 'image/gif') 
        $image = imagecreatefromgif($source);

    elseif ($info['mime'] == 'image/png') 
        $image = imagecreatefrompng($source);

    imagejpeg($image, $destination, $quality);

    return $destination;
}

$source_img = 'source.jpg';
$destination_img = 'destination .jpg';

$d = compress($source_img, $destination_img, 90);
?>

$d = compress($source_img, $destination_img, 90);

This is just a php function that passes the source image ( i.e., $source_img ), destination image ( $destination_img ) and quality for the image that will take to compress ( i.e., 90 ).

$info = getimagesize($source);

The getimagesize() function is used to find the size of any given image file and return the dimensions along with the file type.

I just found a solution for jaxrs-ri-2.16 - simply use

String output = response.readEntity(String.class)

this delivers the content as expected.

It seems that in the debug log for Java 6 the request is send in SSLv2 format.

main, WRITE: SSLv2 client hello message, length = 110

This is not mentioned as enabled by default in Java 7.
Change the client to use SSLv3 and above to avoid such interoperability issues.

Look for differences in JSSE providers in Java 7 and Java 6

I would have thought that it would be better to use stat to find the size of a file, since the filesystem knows it already, rather than causing the whole file to have to be read with awk or wc - especially if it is a multi-GB file or one that may be non-resident in the file-system on an HSM.

stat -c%s file

Yes, I concede it doesn't account for multi-byte characters, but would add that the OP has never clarified whether that is/was an issue.

You Need to write a custom Deserializer and then loop it and get the values of the hasmap.

Custom Deserializer:-

public class UserDetailsDeserializer implements JsonDeserializer<AllUserDetailsKeyModel> {
  /*
    bebebejunskjd:{
      "email": "[email protected]",
          "mobileNum": "12345678",
          "password": "1234567",
          "username": "akhil"}*/
  @Override public AllUserDetailsKeyModel deserialize(JsonElement json, Type typeOfT,
      JsonDeserializationContext context) throws JsonParseException {

    final JsonObject jsonObject = json.getAsJsonObject();

    Gson gson = new Gson();

    Type AllUserDetailsResponseModel =
        new TypeToken<HashMap<String, AllUserDetailsResponseModel>>(){}.getType();

    HashMap<String, AllUserDetailsResponseModel> user =
        gson.fromJson(jsonObject, AllUserDetailsResponseModel);
    AllUserDetailsKeyModel result = new AllUserDetailsKeyModel();
    result.setResult(user);
    return result;
  }


}

The code in comments is my object model and u should replaceAllUserDetailsKeyModel with your model class and add this to the rest client like below:-

private Converter.Factory createGsonConverter() {
    GsonBuilder gsonBuilder = new GsonBuilder();
    gsonBuilder.registerTypeAdapter(AllUserDetailsKeyModel.class, new UserDetailsDeserializer());
    Gson gson = gsonBuilder.create();
    return GsonConverterFactory.create(gson);
  }

This the custom Convertor for Retrofit.

In your onResponse you just loop with hasmaps and get value by key and my model class looks like below:-

public class AllUserDetailsKeyModel {

  private Map<String, AllUserDetailsResponseModel> result;

  public Map<String, AllUserDetailsResponseModel> getResult() {
    return result;
  }

  public void setResult(Map<String, AllUserDetailsResponseModel> result) {
    this.result = result;
  }

}

probably you need to give a Type T where T is your data Type and my model consists only of a hashmap and getters and setters for that.

And finally set Custom Convertor to retrofit like below:- .addConverterFactory(createGsonConverter())

Let me know if you need more clarifications.

So, this is an awfully old question which already has an accepted answer, but I believe that this answer would have been chosen had it been posted four years ago.

I solved this purely with CSS, and with NO EXTRA DOM ELEMENTS! This means that the two colors are purely that, just background colors of ONE ELEMENT, not the background color of two.

I used a gradient and, because I set the color stops so closely together, it looks as if the colors are distinct and that they do not blend.

Here is the gradient in native syntax:

background: repeating-linear-gradient(#74ABDD, #74ABDD 49.9%, #498DCB 50.1%, #498DCB 100%);

Color #74ABDD starts at 0% and is still #74ABDD at 49.9%.

Then, I force the gradient to shift to my next color within 0.2% of the elements height, creating what appears to be a very solid line between the two colors.

Here is the outcome:

And here's my JSFiddle!

Have fun!

I got it to work on ASP.NET MVC 5

I saw many people interested in and suffering from this code and i know it's really confusing and disrupting for the first time.

Notes

• worked on MVC 5 on both server and client side :D
• I didn't install "ExpressiveAnnotations" library at all.
• I'm taking about the Original code from "@Dan Hunex", Find him above

Tips To Fix This Error

"The type System.Web.Mvc.RequiredAttributeAdapter must have a public constructor which accepts three parameters of types System.Web.Mvc.ModelMetadata, System.Web.Mvc.ControllerContext, and ExpressiveAnnotations.Attributes.RequiredIfAttribute Parameter name: adapterType"

Tip #1: make sure that you're inheriting from 'ValidationAttribute' not from 'RequiredAttribute'

 public class RequiredIfAttribute : ValidationAttribute, IClientValidatable { ...}

Tip #2: OR remove this entire line from 'Global.asax', It is not needed at all in the newer version of the code (after edit by @Dan_Hunex), and yes this line was a must in the old version ...

DataAnnotationsModelValidatorProvider.RegisterAdapter(typeof(RequiredIfAttribute), typeof(RequiredAttributeAdapter));

Tips To Get The Javascript Code Part Work

1- put the code in a new js file (ex:requiredIfValidator.js)

2- warp the code inside a $(document).ready(function(){........});

3- include our js file after including the JQuery validation libraries, So it look like this now :

@Scripts.Render("~/bundles/jqueryval")
<script src="~/Content/JS/requiredIfValidator.js"></script>

4- Edit the C# code

from

rule.ValidationParameters["dependentproperty"] = (context as ViewContext).ViewData.TemplateInfo.GetFullHtmlFieldId(PropertyName);

to

rule.ValidationParameters["dependentproperty"] = PropertyName;

and from

if (dependentValue.ToString() == DesiredValue.ToString())

to

if (dependentValue != null && dependentValue.ToString() == DesiredValue.ToString())

My Entire Code Up and Running

Global.asax

Nothing to add here, keep it clean

requiredIfValidator.js

create this file in ~/content or in ~/scripts folder

    $.validator.unobtrusive.adapters.add('requiredif', ['dependentproperty', 'desiredvalue'], function (options)
{
    options.rules['requiredif'] = options.params;
    options.messages['requiredif'] = options.message;
});


$(document).ready(function ()
{

    $.validator.addMethod('requiredif', function (value, element, parameters) {
        var desiredvalue = parameters.desiredvalue;
        desiredvalue = (desiredvalue == null ? '' : desiredvalue).toString();
        var controlType = $("input[id$='" + parameters.dependentproperty + "']").attr("type");
        var actualvalue = {}
        if (controlType == "checkbox" || controlType == "radio") {
            var control = $("input[id$='" + parameters.dependentproperty + "']:checked");
            actualvalue = control.val();
        } else {
            actualvalue = $("#" + parameters.dependentproperty).val();
        }
        if ($.trim(desiredvalue).toLowerCase() === $.trim(actualvalue).toLocaleLowerCase()) {
            var isValid = $.validator.methods.required.call(this, value, element, parameters);
            return isValid;
        }
        return true;
    });
});

_Layout.cshtml or the View

@Scripts.Render("~/bundles/jqueryval")
<script src="~/Content/JS/requiredIfValidator.js"></script>

RequiredIfAttribute.cs Class

create it some where in your project, For example in ~/models/customValidation/

    using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.Web.Mvc;

namespace Your_Project_Name.Models.CustomValidation

        private String PropertyName { get; set; }
        private Object DesiredValue { get; set; }
        private readonly RequiredAttribute _innerAttribute;

        public RequiredIfAttribute(String propertyName, Object desiredvalue)
        {
            PropertyName = propertyName;
            DesiredValue = desiredvalue;
            _innerAttribute = new RequiredAttribute();
        }

        protected override ValidationResult IsValid(object value, ValidationContext context)
        {
            var dependentValue = context.ObjectInstance.GetType().GetProperty(PropertyName).GetValue(context.ObjectInstance, null);

            if (dependentValue != null && dependentValue.ToString() == DesiredValue.ToString())
            {
                if (!_innerAttribute.IsValid(value))
                {
                    return new ValidationResult(FormatErrorMessage(context.DisplayName), new[] { context.MemberName });
                }
            }
            return ValidationResult.Success;
        }

        public IEnumerable<ModelClientValidationRule> GetClientValidationRules(ModelMetadata metadata, ControllerContext context)
        {
            var rule = new ModelClientValidationRule
            {
                ErrorMessage = ErrorMessageString,
                ValidationType = "requiredif",
            };
            rule.ValidationParameters["dependentproperty"] = PropertyName;
            rule.ValidationParameters["desiredvalue"] = DesiredValue is bool ? DesiredValue.ToString().ToLower() : DesiredValue;

            yield return rule;
        }
    }
}

The Model

    using System;

        [RequiredIf("ORG_BY_CD", "5", ErrorMessage = "Coordinator ID is required")] // This means: IF 'ORG_BY_CD' is equal 5 (for the example)  > make 'COR_CI_ID_NUM' required and apply its all validation / data annotations
        [RegularExpression("[0-9]+", ErrorMessage = "Enter Numbers Only")]
        [MaxLength(9, ErrorMessage = "Enter a valid ID Number")]
        [MinLength(9, ErrorMessage = "Enter a valid ID Number")]
        public string COR_CI_ID_NUM { get; set; }
    }

Hope this was helpful

Thank You

Simplified way of doing this based on the accepted answer.

In my case I needed to check if current date (Today) is pithing the range of two other dates so used newDate() instead of hardcoded values but you can get the point how you can use hardcoded dates.

var currentDate = new Date().toJSON().slice(0,10);
var from = new Date('2020/01/01');
var to   = new Date('2020/01/31');
var check = new Date(currentDate);

console.log(check > from && check < to);

You should be able just to type bash into the terminal to switch to bash, and then type zsh to switch to zsh. Works for me at least.

I ended up abandoning the code for my other answer to this question and going with this answer instead.

I believe the best way to do this is to not use ng-show and ng-animate at all.

/* Executes jQuery slideDown and slideUp based on value of toggle-slidedown 
   attribute.  Set duration using slidedown-duration attribute.  Add the 
   toggle-required attribute to all contained form controls which are
   input, select, or textarea.  Defaults to hidden (up) if not specified
   in slidedown-init attribute.  */
fboApp.directive('toggleSlidedown', function(){
    return {
        restrict: 'A',
        link: function (scope, elem, attrs, ctrl) {
            if ('down' == attrs.slidedownInit){
                elem.css('display', '');
            } else {
                elem.css('display', 'none');
            }
            scope.$watch(attrs.toggleSlidedown, function (val) {
                var duration = _.isUndefined(attrs.slidedownDuration) ? 150 : attrs.slidedownDuration;
                if (val) {
                    elem.slideDown(duration);
                } else {
                    elem.slideUp(duration);
                }
            });
        }
    }
});

Yep - 'E' does the trick

http://download.oracle.com/javase/6/docs/api/java/text/SimpleDateFormat.html

Date date = new Date();
DateFormat df = new SimpleDateFormat("yyyy-MM-E");
System.out.println(df.format(date));

I think the Wikipedia-article on Deprecation answers this one pretty well:

In the process of authoring computer software, its standards or documentation, deprecation is a status applied to software features to indicate that they should be avoided, typically because they have been superseded. Although deprecated features remain in the software, their use may raise warning messages recommending alternative practices, and deprecation may indicate that the feature will be removed in the future. Features are deprecated—rather than immediately removed—in order to provide backward compatibility, and give programmers who have used the feature time to bring their code into compliance with the new standard.

When you are not sure of the number of rows, then you can do it this way:

followers_df.index = range(len(followers_df))

We have this issue as well (or a variant).

Try the following:

1) Add a timeout to p.WaitForExit(nnnn); where nnnn is in milliseconds.

2) Put the ReadToEnd call before the WaitForExit call. This is what we've seen MS recommend.

You can use the following command to end an ongoing process:

ctrl + c

You could simply have: var result = (str == "true").

If after calling "csrutil disabled" still your command does not work, try with "sudo" in terminal, for example:

sudo mv geckodriver /usr/local/bin

And it should work.

You can use the

jar tf example.jar

In asp.net is more to do, to get completely running under another namespace.

• Copy your source folder and rename it to your new project name.
• Open it and Replace all by Ctrl + H and be sure to include all Replace everything
• Press F2 on your Projectname and rename it to your new project name
• go to your project properties and adjust it, coz everything has gone and you need to make a new Debug Profile Profile to Create
• All dependencies have now an exclamation mark - restart visual studio
• Clean your solution and Run it and it should work :)

1. Make your activity A in manifest file: launchMode = "singleInstance"
2. When the user clicks new, do FirstActivity.fa.finish(); and call the new Intent.
3. When the user clicks modify, call the new Intent or simply finish activity B.

The answer of Shyam was right. I already faced with this issue before. It's not a problem, it's a SPRING feature. "Transaction rolled back because it has been marked as rollback-only" is acceptable.

Conclusion

• USE REQUIRES_NEW if you want to commit what did you do before exception (Local commit)
• USE REQUIRED if you want to commit only when all processes are done (Global commit) And you just need to ignore "Transaction rolled back because it has been marked as rollback-only" exception. But you need to try-catch out side the caller processNextRegistrationMessage() to have a meaning log.

Let's me explain more detail:

Question: How many Transaction we have? Answer: Only one

Because you config the PROPAGATION is PROPAGATION_REQUIRED so that the @Transaction persist() is using the same transaction with the caller-processNextRegistrationMessage(). Actually, when we get an exception, the Spring will set rollBackOnly for the TransactionManager so the Spring will rollback just only one Transaction.

Question: But we have a try-catch outside (), why does it happen this exception? Answer Because of unique Transaction

1. When persist() method has an exception

2. Go to the catch outside

   Spring will set the rollBackOnly to true -> it determine we must 
   rollback the caller (processNextRegistrationMessage) also.
   

3. The persist() will rollback itself first.

4. Throw an UnexpectedRollbackException to inform that, we need to rollback the caller also.
5. The try-catch in run() will catch UnexpectedRollbackException and print the stack trace

Question: Why we change PROPAGATION to REQUIRES_NEW, it works?

Answer: Because now the processNextRegistrationMessage() and persist() are in the different transaction so that they only rollback their transaction.

Thanks

To get a list of the words that appear more than once together with how often they occur, use a combination of GROUP BY and HAVING:

SELECT word, COUNT(*) AS cnt
FROM words
GROUP BY word
HAVING cnt > 1

To find the number of words in the above result set, use that as a subquery and count the rows in an outer query:

SELECT COUNT(*)
FROM
(
    SELECT NULL
    FROM words
    GROUP BY word
    HAVING COUNT(*) > 1
) T1

Recently an awesome tool called Get Waves was introduced where you can simply from UI create your own waves and then export this to SVG format. This is as simple as going to the https://getwaves.io/ website and enjoying it!

Edit:

Recently I've discovered also a new tool - https://shapedivider.app/

In your main.ts, you are bootstrapping both your AppModule and your App. It should just be the AppModule, which then bootstraps the App.

If you compare your main.ts to the docs you'll see the difference - just remove all references to App from main.ts

Though this is not recent, I thought, my answer can still help others:

cd tomcat/lib 
java -cp catalina.jar org.apache.catalina.util.ServerInfo

and that's it.

Server version: Apache Tomcat/7.0.30

The JAVA Documentation says:

java [ options ] -jar file.jar [ argument ... ]

and

... Non-option arguments after the class name or JAR file name are passed to the main function...

Maybe you have to put the arguments in single quotes.

Seems to work

$(".selector").change(function() {

    var $value = $(this).val();

    var $title = $(this).children('option[value='+$value+']').html();

    $('#bacon').val($title);

});

Just check with your firebug. And don't put css on hidden input.

I wrote a little bash onliner that you can write to a script to get a friendly output:

mysql_references_to:

mysql -uUSER -pPASS -A DB_NAME -se "USE information_schema; SELECT * FROM KEY_COLUMN_USAGE WHERE REFERENCED_TABLE_NAME = '$1' AND REFERENCED_COLUMN_NAME = 'id'\G" | sed 's/^[ \t]*//;s/[ \t]*$//' |egrep "\<TABLE_NAME|\<COLUMN_NAME" |sed 's/TABLE_NAME: /./g' |sed 's/COLUMN_NAME: //g' | paste -sd "," -| tr '.' '\n' |sed 's/,$//' |sed 's/,/./'

So the execution: mysql_references_to transaccion (where transaccion is a random table name) gives an output like this:

carrito_transaccion.transaccion_id
comanda_detalle.transaccion_id
comanda_detalle_devolucion.transaccion_positiva_id
comanda_detalle_devolucion.transaccion_negativa_id
comanda_transaccion.transaccion_id
cuenta_operacion.transaccion_id
...

I was dealing with this issue after upgrading from Visual Studio 2013 to Visual Studio 2015 After trying most of the advice found in this and other similar SO posts, I finally found the problem. The first part of the fix was to update all of my NuGet stuff to the latest version (you might need to do this in VS13 if you are experiencing the Nuget bug) after, I had to, as you may need to, fix the versions listed in the Views Web.config. This includes:

1. Fix MVC versions and its child libraries to the new version (expand the References then right click onSytem.Web.MVC then Properties to get your version)
2. Fix the Razor version.

Mine looked like this:

This works like a charm, fast and accurate:

function replace_string_in_file($filename, $string_to_replace, $replace_with){
    $content=file_get_contents($filename);
    $content_chunks=explode($string_to_replace, $content);
    $content=implode($replace_with, $content_chunks);
    file_put_contents($filename, $content);

Usage:

$filename="users/data/letter.txt";
$string_to_replace="US$";
$replace_with="Yuan";
replace_string_in_file($filename, $string_to_replace, $replace_with);

// never forget about EXPLODE when it comes about string parsing // it's a powerful and fast tool

The docker run command first creates a writeable container layer over the specified image, and then starts it using the specified command.

That is, docker run is equivalent to the API /containers/create then /containers/(id)/start.

You do not run an existing container, you docker exec to it (since docker 1.3).
You can restart an exited container.

You don't need a custom control, just put your container in a border element:

<Border BorderBrush="#FF000000" BorderThickness="1" CornerRadius="8">
   <Grid/>
</Border>

You can replace the <Grid/> with any of the layout containers...

You can use SVGs to connect two divs using only HTML and CSS:

<div id="div1" style="width: 100px; height: 100px; top:0; left:0; background:#777; position:absolute;"></div>
<div id="div2" style="width: 100px; height: 100px; top:300px; left:300px; background:#333; position:absolute;"></div>

(please use seperate css file for styling)

Create a svg line and use this line to connect above divs

<svg width="500" height="500"><line x1="50" y1="50" x2="350" y2="350" stroke="black"/></svg>

where,

x1,y1 indicates center of first div and
x2,y2 indicates center of second div

You can check how it looks in the snippet below

<div id="div1" style="width: 100px; height: 100px; top:0; left:0; background:#777; position:absolute;"></div>_x000D_
<div id="div2" style="width: 100px; height: 100px; top:300px; left:300px; background:#333; position:absolute;"></div>_x000D_
_x000D_
<svg width="500" height="500"><line x1="50" y1="50" x2="350" y2="350" stroke="black"/></svg>

In C++, there is no difference in main() and main(void).

But in C, main() will be called with any number of parameters.

Example:

main ( ){
    main(10,"abc",12.28);
    //Works fine !
    //It won't give the error. The code will compile successfully.
    //(May cause Segmentation fault when run)
}

main(void) will be called without any parameters. If we try to pass then this end up leading to a compiler error.

Example:

main (void) {
     main(10,"abc",12.13);
     //This throws "error: too many arguments to function ‘main’ "
}

Description

You can do this using jQuery.offset() and jQuery.animate().

Check out the jsFiddle Demonstration.

Sample

function scrollToAnchor(aid){
    var aTag = $("a[name='"+ aid +"']");
    $('html,body').animate({scrollTop: aTag.offset().top},'slow');
}

scrollToAnchor('id3');

To add to the answers above, the App Domain is required for security reasons. For example, your app has been sending the browser to "www.example.com/PAGE_NAME_HERE", but suddenly a third party application (or something else) sends the user to "www.supposedlymaliciouswebsite.com/PAGE_HERE", then a 191 error is thrown saying that this wasn't part of the app domains you listed in your Facebook application settings.

Alternatively, have a look at autotest.

Running autotest in a command window will mean that the spec file will be executed whenever you save it. Also, it will be run whenever the file you are speccing is run.

For instance, if you have a model spec file called person_spec.rb, and a model file that it is speccing called person.rb, then whenever you save either of these files from your editor, the spec file will be executed.

This was already answered but I think the --global config is not covered properly.

By running npm config rm proxy you remove proxy from user configuration.
This can be easily verified by running: npm config list.

If there is proxy or https-proxy setting set in global config you have to use --global in the command to remove it.

So at the end this will clean-up proxies from both local and global configs:

npm config rm proxy
npm config rm https-proxy
npm config --global rm proxy
npm config --global rm https-proxy

The code you posted gives the critical value for a one-sided test (Hence the answer to you question is simply:

abs(qt(0.25, 40)) # 75% confidence, 1 sided (same as qt(0.75, 40))
abs(qt(0.01, 40)) # 99% confidence, 1 sided (same as qt(0.99, 40))

Note that the t-distribution is symmetric. For a 2-sided test (say with 99% confidence) you can use the critical value

abs(qt(0.01/2, 40)) # 99% confidence, 2 sided

int is a primitive type, you can read what does mean a primitive type in java here, and a Map is an interface that has to objects as input:

public interface Map<K extends Object, V extends Object>

object means a class, and it means also that you can create an other class that exends from it, but you can not create a class that exends from int. So you can not use int variable as an object. I have tow solutions for your problem:

Map<String, Integer> map = new HashMap<>();

or

Map<String, int[]> map = new HashMap<>();
int x = 1;

//put x in map
int[] x_ = new int[]{x};
map.put("x", x_);

//get the value of x
int y = map.get("x")[0];

You have to set the associatedEmployee on the Vehicle before persisting the Employee.

Employee newEmployee = new Employee("matt");
vehicle1.setAssociatedEmployee(newEmployee);
vehicles.add(vehicle1);

newEmployee.setVehicles(vehicles);

Employee savedEmployee = employeeDao.persistOrMerge(newEmployee);

Here's my expression dark theme for WPF controls.

Imagine you have an abstract superclass that is generic:

public abstract class Foo<? extends T> {}

And then you have a second class that extends Foo with a generic Bar that extends T:

public class Second extends Foo<Bar> {}

You can get the class Bar.class in the Foo class by selecting the Type (from bert bruynooghe answer) and infering it using Class instance:

Type mySuperclass = myFoo.getClass().getGenericSuperclass();
Type tType = ((ParameterizedType)mySuperclass).getActualTypeArguments()[0];
//Parse it as String
String className = tType.toString().split(" ")[1];
Class clazz = Class.forName(className);

You have to note this operation is not ideal, so it is a good idea to cache the computed value to avoid multiple calculations on this. One of the typical uses is in generic DAO implementation.

The final implementation:

public abstract class Foo<T> {

    private Class<T> inferedClass;

    public Class<T> getGenericClass(){
        if(inferedClass == null){
            Type mySuperclass = getClass().getGenericSuperclass();
            Type tType = ((ParameterizedType)mySuperclass).getActualTypeArguments()[0];
            String className = tType.toString().split(" ")[1];
            inferedClass = Class.forName(className);
        }
        return inferedClass;
    }
}

The value returned is Bar.class when invoked from Foo class in other function or from Bar class.

int[] getAdminIDList(String tableName, String attributeName, int value) throws SQLException {
    ArrayList list = null;
    Statement statement = conn.createStatement();
    ResultSet result = statement.executeQuery("SELECT admin_id FROM " + tableName + " WHERE " + attributeName + "='" + value + "'");
    while (result.next()) {
        list.add(result.getInt(1));
    }
    statement.close();
    int id[] = new int[list.size()];
    for (int i = 0; i < id.length; i++) {
        try {
            id[i] = ((Integer) list.get(i)).intValue();
        } catch(NullPointerException ne) {
        } catch(ClassCastException ch) {}
    }
    return id;
}
// enter code here

This code shows why ArrayList is important and why we use it. Simply casting int from Object. May be its helpful.

If you're using SSMS (or old school Enterprise Manager) to edit the table directly, press CTRL+0 to add a null.

$personCount=1;
while ($personCount < 10) {
    $result=0;
    $result.= $personCount . "person ";
    $personCount++;

}

Use StringBuilder class, like so:

StringBuilder meme = new StringBuilder(" ");

// Convert and append your double variable
meme.append(String.valueOf(doubleVariable));

// Convert string builder to string
jTextField9.setText(meme.toString());

You will get you desired output.

Simple Description!

The index is nothing but a data structure that stores the values for a specific column in a table. An index is created on a column of a table.

Example: We have a database table called User with three columns – Name, Age and Address. Assume that the User table has thousands of rows.

Now, let’s say that we want to run a query to find all the details of any users who are named 'John'. If we run the following query:

SELECT * FROM User 
WHERE Name = 'John'

The database software would literally have to look at every single row in the User table to see if the Name for that row is ‘John’. This will take a long time.

This is where index helps us: index is used to speed up search queries by essentially cutting down the number of records/rows in a table that needs to be examined.

How to create an index:

CREATE INDEX name_index
ON User (Name)

An index consists of column values(Eg: John) from one table, and those values are stored in a data structure.

So now the database will use the index to find employees named John because the index will presumably be sorted alphabetically by the Users name. And, because it is sorted, it means searching for a name is a lot faster because all names starting with a “J” will be right next to each other in the index!

You can also use the cell property.

Cells(1, 1).Value = "Hey, what's up?"

Make sure to use a . before Cells(1,1).Value as in .Cells(1,1).Value, if you are using it within With function. If you are selecting some sheet.

Important behavior changes between old and new style classes

• super added
• MRO changed (explained below)
• descriptors added
• new style class objects cannot be raised unless derived from Exception (example below)
• __slots__ added

MRO (Method Resolution Order) changed

It was mentioned in other answers, but here goes a concrete example of the difference between classic MRO and C3 MRO (used in new style classes).

The question is the order in which attributes (which include methods and member variables) are searched for in multiple inheritance.

Classic classes do a depth-first search from left to right. Stop on the first match. They do not have the __mro__ attribute.

class C: i = 0
class C1(C): pass
class C2(C): i = 2
class C12(C1, C2): pass
class C21(C2, C1): pass

assert C12().i == 0
assert C21().i == 2

try:
    C12.__mro__
except AttributeError:
    pass
else:
    assert False

New-style classes MRO is more complicated to synthesize in a single English sentence. It is explained in detail here. One of its properties is that a base class is only searched for once all its derived classes have been. They have the __mro__ attribute which shows the search order.

class C(object): i = 0
class C1(C): pass
class C2(C): i = 2
class C12(C1, C2): pass
class C21(C2, C1): pass

assert C12().i == 2
assert C21().i == 2

assert C12.__mro__ == (C12, C1, C2, C, object)
assert C21.__mro__ == (C21, C2, C1, C, object)

New style class objects cannot be raised unless derived from Exception

Around Python 2.5 many classes could be raised, and around Python 2.6 this was removed. On Python 2.7.3:

# OK, old:
class Old: pass
try:
    raise Old()
except Old:
    pass
else:
    assert False

# TypeError, new not derived from `Exception`.
class New(object): pass
try:
    raise New()
except TypeError:
    pass
else:
    assert False

# OK, derived from `Exception`.
class New(Exception): pass
try:
    raise New()
except New:
    pass
else:
    assert False

# `'str'` is a new style object, so you can't raise it:
try:
    raise 'str'
except TypeError:
    pass
else:
    assert False

Without using any other libraries:

import * as axios from "axios";

// Mock out all top level functions, such as get, put, delete and post:
jest.mock("axios");

// ...

test("good response", () => {
  axios.get.mockImplementation(() => Promise.resolve({ data: {...} }));
  // ...
});

test("bad response", () => {
  axios.get.mockImplementation(() => Promise.reject({ ... }));
  // ...
});

It is possible to specify the response code:

axios.get.mockImplementation(() => Promise.resolve({ status: 200, data: {...} }));

It is possible to change the mock based on the parameters:

axios.get.mockImplementation((url) => {
    if (url === 'www.example.com') {
        return Promise.resolve({ data: {...} });
    } else {
        //...
    }
});

Jest v23 introduced some syntactic sugar for mocking Promises:

axios.get.mockImplementation(() => Promise.resolve({ data: {...} }));

It can be simplified to

axios.get.mockResolvedValue({ data: {...} });

There is also an equivalent for rejected promises: mockRejectedValue.

Further Reading:

• Jest mocking documentation
• A GitHub discussion that explains about the scope of the jest.mock("axios") line.
• Another answer of mine which addresses applying the techniques above to Axios request interceptors.

just use inner join because group by won't work with multiple columns saying not contained in either an aggregate function.

SELECT a.*
FROM yourtable a
INNER JOIN 
  (SELECT yourcolumn,
    MIN(id) as id
  FROM yourtable 
  GROUP BY yourcolumn
) AS b
  ON a.yourcolumn= b.yourcolumn
  AND a.id = b.id;

Using Date pattern yyyy-MM-dd'T'HH:mm:ss.SSS'Z' and Java 8 you could do

String string = "2018-04-10T04:00:00.000Z";
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'", Locale.ENGLISH);
LocalDate date = LocalDate.parse(string, formatter);
System.out.println(date);

Update: For pre 26 use Joda time

String string = "2018-04-10T04:00:00.000Z";
DateTimeFormatter formatter = DateTimeFormat.forPattern("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
LocalDate date = org.joda.time.LocalDate.parse(string, formatter);

In app/build.gradle file, add like this-

dependencies {    
    compile 'joda-time:joda-time:2.9.4'
}

USE [DATABASE]

DECLARE @USERNAME VARCHAR(500)

DECLARE @STRSQL NVARCHAR(MAX)

SET @USERNAME='[USERNAME] '
SET @STRSQL=''

select @STRSQL+=CHAR(13)+'GRANT EXECUTE ON ['+ s.name+'].['+obj.name+'] TO'+@USERNAME+';'
from
    sys.all_objects as obj
inner join
    sys.schemas s ON obj.schema_id = s.schema_id
where obj.type in ('P','V','FK')
AND s.NAME NOT IN ('SYS','INFORMATION_SCHEMA')


EXEC SP_EXECUTESQL @STRSQL

var str = "I'm a very^ we!rd* Str!ng.";
$('body').html(str.replace(/[^a-z0-9\s]/gi, " ").replace(/^\s+|\s+$|\s+(?=\s)/g, "").replace(/[_\s]/g, "-").toLowerCase());

First regex remove special characters with spaces than remove extra spaces from string and the last regex replace space with "-"

Simple, use array_intersect() instead:

$result = array_intersect($array1, $array2);

Another method for cleaner argument passing would be splatting.

Define your parameters and values as a hashtable like this:

$params = @{ 'class' = 'Win32_BIOS';
             'computername'='SERVER-R2';
             'filter'='drivetype=3';
             'credential'='Administrator' }

And then call your commandlet like this:

Get-WmiObject @params

This is how I got 1.7 to work with Eclipse. I hope it helps.

1. I Downloaded the latest OpenJDK 1.7 universal (32/64 bits) JDK from Mac OS/X branch from http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html
2. copied the jdk to /Library/Java/JavaVirtualMachines/ next to the default 1.6.0 one
3. In Eclipse > Preferences > Java > Installed JREs you add a new one, of type MacOS X VM, and set the home as /Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home and name Java SE 7 (OpenJDK)
4. Click Finish
5. Set the added JRE as default

that should be it :)

Disabling certificate checking is the wrong solution, and radically insecure.

The correct solution is to import the self-signed certificate into your truststore. An even more correct solution is to get the certificate signed by a CA.

If this is 'only for testing' it is still necessary to test the production configuration. Testing something else isn't a test at all, it's just a waste of time.

I think you don't have to use sub query in this scenario.You can directly left outer join the DEPRMNT table .

While using Left Outer Join ,don't use columns in the RHS table of the join in the where condition, you ll get wrong output

Get started quickly

You simply type vim into the terminal to open it and start a new file.

You can pass a filename as an option and it will open that file, e.g. vim main.c. You can open multiple files by passing multiple file arguments.

Vim has different modes, unlike most editors you have probably used. You begin in NORMAL mode, which is where you will spend most of your time once you become familiar with vim.

To return to NORMAL mode after changing to a different mode, press Esc. It's a good idea to map your Caps Lock key to Esc, as it's closer and nobody really uses the Caps Lock key.

The first mode to try is INSERT mode, which is entered with a for append after cursor, or i for insert before cursor.

To enter VISUAL mode, where you can select text, use v. There are many other variants of this mode, which you will discover as you learn more about vim.

To save your file, ensure you're in NORMAL mode and then enter the command :w. When you press :, you will see your command appear in the bottom status bar. To save and exit, use :x. To quit without saving, use :q. If you had made a change you wanted to discard, use :q!.

Configure vim to your liking

You can edit your ~/.vimrc file to configure vim to your liking. It's best to look at a few first (here's mine) and then decide which options suits your style.

This is how mine looks:

To get the file explorer on the left, use NERDTree. For the status bar, use vim-airline. Finally, the color scheme is solarized.

Further learning

You can use man vim for some help inside the terminal. Alternatively, run vimtutor which is a good hands-on starting point.

It's a good idea to print out a Vim Cheatsheet and keep it in front of you while you're learning vim.

Good luck!

Use Navigator:-

The navigator is an object that contains all information about the client machine's browser.

navigator.appName returns the name of the client machine's browser.

navigator.appName === 'Microsoft Internet Explorer' ||  !!(navigator.userAgent.match(/Trident/) || navigator.userAgent.match(/rv:11/)) || (typeof $.browser !== "undefined" && $.browser.msie === 1) ? alert("Please dont use IE.") : alert("This is not IE")

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

I know this is 8 years old, but no one seems to have actually read and answered the question.

You can call .values() on a dict to get a list of the inner dicts and thus access them by index.

>>> mydict = {
...  'Apple': {'American':'16', 'Mexican':10, 'Chinese':5},
...  'Grapes':{'Arabian':'25','Indian':'20'} }

>>>mylist = list(mydict.values())
>>>mylist[0]
{'American':'16', 'Mexican':10, 'Chinese':5},
>>>mylist[1]
{'Arabian':'25','Indian':'20'}

>>>myInnerList1 = list(mylist[0].values())
>>>myInnerList1
['16', 10, 5]
>>>myInnerList2 = list(mylist[1].values())
>>>myInnerList2
['25', '20']

This worked for me.
