The issue is that you are not able to get a connection to MYSQL database and hence it is throwing an error saying that cannot build a session factory.

Please see the error below:

 Caused by: java.sql.SQLException: Access denied for user ''@'localhost' (using password: NO) 

which points to username not getting populated.

Please recheck system properties

dataSource.setUsername(System.getProperty("root"));

some packages seems to be missing as well pointing to a dependency issue:

package org.gjt.mm.mysql does not exist

Please run a mvn dependency:tree command to check for dependencies

This was my stupidity, but a stupidity that was not easy to identify :).

Problem:

1. My code is compiled on Jdk 1.8.
2. My eclipse, had JDK 1.8 as the compiler.
3. My tomcat in eclipse was using Java 1.7 for its container, hence it was not able to understand the .class files which were compiled using 1.8.
4. To avoid the problem, ensure in your eclipse, double click on your server -> Open Launch configuration -> Classpath -> JRE System Library -> Give the JDK/JRE of the compiled version of java class, in my case, it had to be JDK 1.8
   5. Post this, clean the server, build and redeploy, start the tomcat.

If you are deploying manually into your server, ensure your JAVA_HOME, JDK_HOME points to the correct JDK which you used to compile the project and build the war.

If you do not like to change JAVA_HOME, JDK_HOME, you can always change the JAVA_HOME and JDK_HOME in catalina.bat(for tomcat server) and that'll enable your life to be easy!

In my case I had to move the @Service annotation from the interface to the implementation class.

If you are sure you haven't messed the jar, then please clean the project and perform mvn clean install. This should solve the problem.

With Spring Boot :

In the pom.xml

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <configuration>
                <addResources>true</addResources>
            </configuration>
        </plugin>
    </plugins>
</build>

Example in class Java

@Configuration
@Slf4j
public class MyAppConfig {
    @Value("${foo}")
    private String foo;
    @Value("${bar}")
    private String bar;
    @Bean("foo")
    public String foo() {
        log.info("foo={}", foo);
        return foo;
    }
    @Bean("bar")
    public String bar() {
        log.info("bar={}", bar);
        return bar;
    }
    [ ... ]

In the properties files :

src/main/resources/application.properties

foo=all-env-foo

src/main/resources/application-rec.properties

bar=rec-bar

src/main/resources/application-prod.properties

bar=prod-bar

In the VM arguments of Application.java

-Dspring.profiles.active=[rec|prod]

Don't forget to run mvn command after modifying the properties !

mvn clean package -Dmaven.test.skip=true

In the log file for -Dspring.profiles.active=rec :

The following profiles are active: rec
foo=all-env-foo
bar=rec-bar

In the log file for -Dspring.profiles.active=prod :

The following profiles are active: prod
foo=all-env-foo
bar=prod-bar

In the log file for -Dspring.profiles.active=local :

Could not resolve placeholder 'bar' in value "${bar}"

Oups, I forget to create application-local.properties.

I had the same error and I had not made any changes to the application config or the web.xml. Multiple tries to revert back some minor changes to code was not clearing the exceptions. Finally it worked after restarting STS.

You will have to annotate your service with @Service since you have said I am using annotations for mapping

According to the stack trace, your issue is that your app cannot find org.apache.commons.dbcp.BasicDataSource, as per this line:

java.lang.ClassNotFoundException: org.apache.commons.dbcp.BasicDataSource

I see that you have commons-dbcp in your list of jars, but for whatever reason, your app is not finding the BasicDataSource class in it.

You have to use at least version 3.2.8.RELEASE of spring-core.

For Maven, set in your pom.xml:

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-core</artifactId>
    <version>3.2.8.RELEASE</version>
</dependency>

Source: http://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/cglib/core/SpringNamingPolicy.html, since 3.2.8.

make sure your properties file exist in classpath directory but not in sub folder of your classpath directory. if it is exist in sub folder then write as below classpath:subfolder/idm.properties

You have an incompatibility between the version of ASM required by Hibernate (asm-1.5.3.jar) and the one required by Spring. But, actually, I wonder why you have asm-2.2.3.jar on your classpath (ASM is bundled in spring.jar and spring-core.jar to avoid such problems AFAIK). See HHH-2222.

i dont know whether it is relevant to your issue, i got similar issue which i got solved by

1) In eclipse right click server and clean

if it still didnt work

2) export the project and delete the project create the project with same name and import the project and add the project to server and run.

Today I found the same issue on a Error reporting app. I don't want to resort to HTML, to allow outlook to display the messages I had to do (assuming StringBuilder sb):

sb.Append(" \r\n\r\n").Append("Exception Time:" + DateTime.UtcNow.ToString());

A DATE value per the SQL standard is YYYY-MM-DD. So even though Oracle stores the time information, my guess is that they're displaying the value in a way that is compatible with the SQL standard. In the standard, there is the TIMESTAMP data type that includes date and time info.

nodeValue is also a standard DOM property you can use:

function showPanel(fieldName) {
  var fieldNameElement = document.getElementById(field_name);
  if(fieldNameElement.firstChild)
    fieldNameElement.firstChild.nodeValue = "New Text";
}

Consider breaking this problem up into two pieces:

1. filter out the items that match the given regular expression
2. determine if that filtered list has 0 matches in it

const sampleStringData = ["frog", "pig", "tiger"];

const matches = sampleStringData.filter((animal) => /any.regex.here/.test(animal));

if (matches.length === 0) {
  console.log("No matches");
}

Fravadona's answer is awesome and correct, but it requires the presence of lscpu. Since it is not present on the system where I need the number of physical cores, I tried to come up with one that relies only on proc/cpuinfo

cat /proc/cpuinfo | grep -B2 'core id' | sed 's/siblings.*/'/ | tr -d '[:space:]' | sed 's/--/\n/'g | sort -u | wc -l

It works perfectly, but unfortunately it isn't as robust as Fravadona's, since it will break if

• the name or order of the fields inside /proc/cpuinfo changes
• grep replaces the line separator it inserts (currently --) by some other string.

BUT, other than that, it works flawlessly :)

Here is a quick explanation of everything that is happening

grep -B2 'core id'

get only the lines we are interested (i.e "core id" and the 2 preceding lines)

sed 's/siblings.*/'/

remove the "siblings..." line

tr -d '[:space:]'

replace spacing chars

sed 's/--/\n/'g

replace the '--' char, which was inserted by grep, by a line break

sort -u

group by "physical id,core id"

wc -l

count the number of lines

Being a total noobie, I was very pleased with myself when this worked. I never thought I would be able to join the required lines together to group by "physical id" and "core id". It is kind of hacky, but works.

If any guru knows a way to simplify this mess, please let me know.

It's been a while since this question was asked, hope can help. Because you can not change or alter the db structure, you can do this. according the postgresql docs.

TRUNCATE -- empty a table or set of tables.

TRUNCATE [ TABLE ] [ ONLY ] name [ * ] [, ... ]
    [ RESTART IDENTITY | CONTINUE IDENTITY ] [ CASCADE | RESTRICT ]

Description

TRUNCATE quickly removes all rows from a set of tables. It has the same effect as an unqualified DELETE on each table, but since it does not actually scan the tables it is faster. Furthermore, it reclaims disk space immediately, rather than requiring a subsequent VACUUM operation. This is most useful on large tables.

Truncate the table othertable, and cascade to any tables that reference othertable via foreign-key constraints:

TRUNCATE othertable CASCADE;

The same, and also reset any associated sequence generators:

TRUNCATE bigtable, fattable RESTART IDENTITY;

Truncate and reset any associated sequence generators:

TRUNCATE revinfo RESTART IDENTITY CASCADE ;

The main reason for a member prefix is to distinguish between a member function local and a member variable with the same name. This is useful if you use getters with the name of the thing.

Consider:

class person
{
public:
    person(const std::string& full_name)
        : full_name_(full_name)
    {}

    const std::string& full_name() const { return full_name_; }
private:
    std::string full_name_;
};

The member variable could not be called full_name in this case. You need to rename the member function to get_full_name() or decorate the member variable somehow.

It's a little tricky because of the nested IFs but here is my answer (confirmed in Google Spreadsheets):

=IF(AND(A2>=0,    A2<500),  "Less than 500", 
 IF(AND(A2>=500,  A2<1000), "Between 500 and 1000", 
 IF(AND(A2>=1000, A2<1500), "Between 1000 and 1500", 
 IF(AND(A2>=1500, A2<2000), "Between 1500 and 2000", "Undefined"))))

Something simply like this will work I guess if it is bash shell.

read -sp "db_password:" password | docker run -itd --name <container_name> --build-arg mysql_db_password=$db_password alpine /bin/bash

Simply read it silently and pass as argument in Docker image. You need to accept the variable as ARG in Dockerfile.

You should not play with the height. Let the text field determine the height based on the font used.

If you want to control the width of the text field then you can use

textField.setColumns(...);

to let the text field determine the preferred width.

Or if you want the width to be the entire width of the parent panel then you need to use an appropriate layout. Maybe the NORTH of a BorderLayout.

See the Swing tutorial on Layout Managers for more information.

Use Object.keys(myObject).length to get the length of object/array

var myObject = new Object();
myObject["firstname"] = "Gareth";
myObject["lastname"] = "Simpson";
myObject["age"] = 21;

console.log(Object.keys(myObject).length); //3

You need seek to the beginning of the file before writing and then use file.truncate() if you want to do inplace replace:

import re

myfile = "path/test.xml"

with open(myfile, "r+") as f:
    data = f.read()
    f.seek(0)
    f.write(re.sub(r"<string>ABC</string>(\s+)<string>(.*)</string>", r"<xyz>ABC</xyz>\1<xyz>\2</xyz>", data))
    f.truncate()

The other way is to read the file then open it again with open(myfile, 'w'):

with open(myfile, "r") as f:
    data = f.read()

with open(myfile, "w") as f:
    f.write(re.sub(r"<string>ABC</string>(\s+)<string>(.*)</string>", r"<xyz>ABC</xyz>\1<xyz>\2</xyz>", data))

Neither truncate nor open(..., 'w') will change the inode number of the file (I tested twice, once with Ubuntu 12.04 NFS and once with ext4).

By the way, this is not really related to Python. The interpreter calls the corresponding low level API. The method truncate() works the same in the C programming language: See http://man7.org/linux/man-pages/man2/truncate.2.html

For my Android projects I've used the Base64 library from here:

http://iharder.net/base64

It's a very extensive library and so far I've had no problems with it.

JSON itself does not specify how dates should be represented, but JavaScript does.

You should use the format emitted by Date's toJSON method:

2012-04-23T18:25:43.511Z

Here's why:

1. It's human readable but also succinct

2. It sorts correctly

3. It includes fractional seconds, which can help re-establish chronology

4. It conforms to ISO 8601

5. ISO 8601 has been well-established internationally for more than a decade

6. ISO 8601 is endorsed by W3C, RFC3339, and XKCD

That being said, every date library ever written can understand "milliseconds since 1970". So for easy portability, ThiefMaster is right.

Very easy..

int (name of integer) = [(name of string, no ()) intValue];

If you also want to block Sundays (or other days) as well as the array of dates, I use this code:

jQuery(function($){

    var disabledDays = [
       "27-4-2016", "25-12-2016", "26-12-2016",
       "4-4-2017", "5-4-2017", "6-4-2017", "6-4-2016", "7-4-2017", "8-4-2017", "9-4-2017"
    ];

   //replace these with the id's of your datepickers
   $("#id-of-first-datepicker,#id-of-second-datepicker").datepicker({
      beforeShowDay: function(date){
         var day = date.getDay();
         var string = jQuery.datepicker.formatDate('d-m-yy', date);
         var isDisabled = ($.inArray(string, disabledDays) != -1);

         //day != 0 disables all Sundays
         return [day != 0 && !isDisabled];
      }
   });
});   

I did this class for that purpose. it produces a variable size matrix ( expandable) when more items are added

In Jackson 2.4, you can convert as follows:

MyClass newJsonNode = jsonObjectMapper.treeToValue(someJsonNode, MyClass.class);

where jsonObjectMapper is a Jackson ObjectMapper.

In older versions of Jackson, it would be

MyClass newJsonNode = jsonObjectMapper.readValue(someJsonNode, MyClass.class);

Use Group by:

int[] values = new []{1,2,3,4,5,4,4,3};

var groups = values.GroupBy(v => v);
foreach(var group in groups)
    Console.WriteLine("Value {0} has {1} items", group.Key, group.Count());

It's because your statement does not produce output.

Besides all the warnings of Darin and lazy (they are right); the question still offerst something to learn.

If you want to execute methods that don't directly produce output, you do:

@{ Response.Redirect("~/Account/LogIn?returnUrl=Products");}

This is also true for rendering partials like:

@{ Html.RenderPartial("_MyPartial"); }

$('div.target').each(function() {
   /* Measure the width of each image. */
   var test = $(this).find('.scrolling img').width();

   /* Find out how many images there are. */
   var testimg = $(this).find('.scrolling img').length;

   /* Do the maths. */
   var final = (test* testimg)*1.2;

   /* Apply the maths to the CSS. */
   $(this).find('scrolling').width(final); 
});

Here you loop through all your div's with class target and you do the calculations. Within this loop you can simply use $(this) to indicate the currently selected <div> tag.

This method works:

audio.pause();
audio.currentTime = 0;

But if you don't want to have to write these two lines of code every time you stop an audio you could do one of two things. The second I think is the more appropriate one and I'm not sure why the "gods of javascript standards" have not made this standard.

First method: create a function and pass the audio

function stopAudio(audio) {
    audio.pause();
    audio.currentTime = 0;
}

//then using it:
stopAudio(audio);

Second method (favoured): extend the Audio class:

Audio.prototype.stop = function() {
    this.pause();
    this.currentTime = 0;
};

I have this in a javascript file I called "AudioPlus.js" which I include in my html before any script that will be dealing with audio.

Then you can call the stop function on audio objects:

audio.stop();

FINALLY CHROME ISSUE WITH "canplaythrough":

I have not tested this in all browsers but this is a problem I came across in Chrome. If you try to set currentTime on an audio that has a "canplaythrough" event listener attached to it then you will trigger that event again which can lead to undesirable results.

So the solution, similar to all cases when you have attached an event listener that you really want to make sure it is not triggered again, is to remove the event listener after the first call. Something like this:

//note using jquery to attach the event. You can use plain javascript as well of course.
$(audio).on("canplaythrough", function() {
    $(this).off("canplaythrough");

    // rest of the code ...
});

BONUS:

Note that you can add even more custom methods to the Audio class (or any native javascript class for that matter).

For example if you wanted a "restart" method that restarted the audio it could look something like:

Audio.prototype.restart= function() {
    this.pause();
    this.currentTime = 0;
    this.play();
};

I had trouble with SQLite3, nStore and Alfred.

What works for me is node-dirty:

path = "#{__dirname}/data/messages.json"
messages = db path

message = 'text': 'Lorem ipsum dolor sit...'

messages.on "load", ->    
    messages.set 'my-unique-key', message, ->
        console.log messages.get('my-unique-key').text

    messages.forEach (key, value) ->
        console.log "Found key: #{key}, val: %j", value

messages.on "drain", ->
    console.log "Saved to #{path}"

In addition to substring answer, you can do it as mystring.SubString(0,3) and check in case statement if its "abc".

But before the switch statement you need to ensure that your mystring is atleast 3 in length.

I think, I've found the best tutorial on how to use the RecyclerView with all basic functions we need (single+multiselection, highlight, ripple, click and remove in multiselection, etc...).

Here it is --> http://enoent.fr/blog/2015/01/18/recyclerview-basics/

Based on that, I was able to create a library "FlexibleAdapter", which extends a SelectableAdapter. I think this must be a responsibility of the Adapter, actually you don't need to rewrite the basic functionalities of Adapter every time, let a library to do it, so you can just reuse the same implementation.

This Adapter is very fast, it works out of the box (you don't need to extend it); you customize the items for every view types you need; ViewHolder are predefined: common events are already implemented: single and long click; it maintains the state after rotation and much much more.

Please have a look and feel free to implement it in your projects.

As a twist of the accepted answer (https://stackoverflow.com/a/255638/986160) assuming that the keys will be associated with signle values in the dictionary. Similar to (https://stackoverflow.com/a/255630/986160) but a bit more elegant. The novelty is in that the consuming class can be used as an enumeration alternative (but for strings too) and that the dictionary implements IEnumerable.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Collections;

namespace MyApp.Dictionaries
{

    class BiDictionary<TFirst, TSecond> : IEnumerable
    {
        IDictionary<TFirst, TSecond> firstToSecond = new Dictionary<TFirst, TSecond>();
        IDictionary<TSecond, TFirst> secondToFirst = new Dictionary<TSecond, TFirst>();

        public void Add(TFirst first, TSecond second)
        {
            firstToSecond.Add(first, second);
            secondToFirst.Add(second, first);
        }

        public TSecond this[TFirst first]
        {
            get { return GetByFirst(first); }
        }

        public TFirst this[TSecond second]
        {
            get { return GetBySecond(second); }
        }

        public TSecond GetByFirst(TFirst first)
        {
            return firstToSecond[first];
        }

        public TFirst GetBySecond(TSecond second)
        {
            return secondToFirst[second];
        }

        public IEnumerator GetEnumerator()
        {
            return GetFirstEnumerator();
        }

        public IEnumerator GetFirstEnumerator()
        {
            return firstToSecond.GetEnumerator();
        }

        public IEnumerator GetSecondEnumerator()
        {
            return secondToFirst.GetEnumerator();
        }
    }
}

And as a consuming class you could have

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace MyApp.Dictionaries
{
    class Greek
    {

        public static readonly string Alpha = "Alpha";
        public static readonly string Beta = "Beta";
        public static readonly string Gamma = "Gamma";
        public static readonly string Delta = "Delta";


        private static readonly BiDictionary<int, string> Dictionary = new BiDictionary<int, string>();


        static Greek() {
            Dictionary.Add(1, Alpha);
            Dictionary.Add(2, Beta);
            Dictionary.Add(3, Gamma);
            Dictionary.Add(4, Delta);
        }

        public static string getById(int id){
            return Dictionary.GetByFirst(id);
        }

        public static int getByValue(string value)
        {
            return Dictionary.GetBySecond(value);
        }

    }
}

The reason why the naive solution doesn't work is that it gives a higher probability density to the points closer to the circle center. In other words the circle that has radius r/2 has probability r/2 of getting a point selected in it, but it has area (number of points) pi*r^2/4.

Therefore we want a radius probability density to have the following property:

The probability of choosing a radius smaller or equal to a given r has to be proportional to the area of the circle with radius r. (because we want to have a uniform distribution on the points and larger areas mean more points)

In other words we want the probability of choosing a radius between [0,r] to be equal to its share of the overall area of the circle. The total circle area is pi*R^2, and the area of the circle with radius r is pi*r^2. Thus we would like the probability of choosing a radius between [0,r] to be (pi*r^2)/(pi*R^2) = r^2/R^2.

Now comes the math:

The probability of choosing a radius between [0,r] is the integral of p(r) dr from 0 to r (that's just because we add all the probabilities of the smaller radii). Thus we want integral(p(r)dr) = r^2/R^2. We can clearly see that R^2 is a constant, so all we need to do is figure out which p(r), when integrated would give us something like r^2. The answer is clearly r * constant. integral(r * constant dr) = r^2/2 * constant. This has to be equal to r^2/R^2, therefore constant = 2/R^2. Thus you have the probability distribution p(r) = r * 2/R^2

Note: Another more intuitive way to think about the problem is to imagine that you are trying to give each circle of radius r a probability density equal to the proportion of the number of points it has on its circumference. Thus a circle which has radius r will have 2 * pi * r "points" on its circumference. The total number of points is pi * R^2. Thus you should give the circle r a probability equal to (2 * pi * r) / (pi * R^2) = 2 * r/R^2. This is much easier to understand and more intuitive, but it's not quite as mathematically sound.

Passing the :value option to f.label will ensure the label tag's for attribute is the same as the id of the corresponding radio_button

<% form_for(@message) do |f| %>
  <%= f.radio_button :contactmethod, 'email' %> 
  <%= f.label :contactmethod, 'Email', :value => 'email' %>
  <%= f.radio_button :contactmethod, 'sms' %>
  <%= f.label :contactmethod, 'SMS', :value => 'sms' %>
<% end %>

See ActionView::Helpers::FormHelper#label

the :value option, which is designed to target labels for radio_button tags

You can derive a class from Runnable, and during the construction (say) pass the parameter in.

Then launch it using Thread.start(Runnable r);

If you mean whilst the thread is running, then simply hold a reference to your derived object in the calling thread, and call the appropriate setter methods (synchronising where appropriate)

make sure you use the POST to insert the data. Actually you were using GET.

You don't need to. Just slap it on there as many times as you want and as often as you want. MDN explains identical event listeners:

If multiple identical EventListeners are registered on the same EventTarget with the same parameters, the duplicate instances are discarded. They do not cause the EventListener to be called twice, and they do not need to be removed manually with the removeEventListener method.

I know this thread is really old but the solution from @Ivan Bondarenko helped me in my situation.

I had the following in my pom.xml.

<build>
    ...
    <plugins>
         <plugin>
                <groupId>com.consol.citrus</groupId>
                <artifactId>citrus-remote-maven-plugin</artifactId>
                <version>${citrus.version}</version>
                <executions>
                    <execution>
                        <id>generate-citrus-war</id>
                        <goals>
                            <goal>test-war</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
    </plugins>
</build>

What I wanted, was to disable the execution of generate-citrus-war for a specific profile and this was the solution:

<profile>
    <id>it</id>
    <build>
        <plugins>
            <plugin>
                <groupId>com.consol.citrus</groupId>
                <artifactId>citrus-remote-maven-plugin</artifactId>
                <version>${citrus.version}</version>
                <executions>
                    <!-- disable generating the war for this profile -->
                    <execution>
                        <id>generate-citrus-war</id>
                        <phase/>
                    </execution>

                    <!-- do something else -->
                    <execution>
                        ...
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>
</profile>

Or you can use an arrow function to define it:

$(document).ready(() => {
  $('#bfCaptchaEntry').click(()=>{
    
  });
});

For better browser support:

$(document).ready(function() {
  $('#bfCaptchaEntry').click(function (){
    
  });
});

Use slicing, rebuilding the string minus the index you want to remove:

newstr = oldstr[:4] + oldstr[5:]

You can also get them with pure javascript.

For example:

new URL(location.href).searchParams.get('page')

For this url: websitename.com/user/?page=1, it would return a value of 1

Answear taken from Php manual strtotime function comments :

echo date( "Y-m-d", strtotime( "2009-01-31 -1 day"));

Or

$date = "2009-01-31";
echo date( "Y-m-d", strtotime( $date . "-1 day"));

What you want is org.mockito.Mockito.CALLS_REAL_METHODS according to the docs:

/**
 * Optional <code>Answer</code> to be used with {@link Mockito#mock(Class, Answer)}
 * <p>
 * {@link Answer} can be used to define the return values of unstubbed invocations.
 * <p>
 * This implementation can be helpful when working with legacy code.
 * When this implementation is used, unstubbed methods will delegate to the real implementation.
 * This is a way to create a partial mock object that calls real methods by default.
 * <p>
 * As usual you are going to read <b>the partial mock warning</b>:
 * Object oriented programming is more less tackling complexity by dividing the complexity into separate, specific, SRPy objects.
 * How does partial mock fit into this paradigm? Well, it just doesn't... 
 * Partial mock usually means that the complexity has been moved to a different method on the same object.
 * In most cases, this is not the way you want to design your application.
 * <p>
 * However, there are rare cases when partial mocks come handy: 
 * dealing with code you cannot change easily (3rd party interfaces, interim refactoring of legacy code etc.)
 * However, I wouldn't use partial mocks for new, test-driven & well-designed code.
 * <p>
 * Example:
 * <pre class="code"><code class="java">
 * Foo mock = mock(Foo.class, CALLS_REAL_METHODS);
 *
 * // this calls the real implementation of Foo.getSomething()
 * value = mock.getSomething();
 *
 * when(mock.getSomething()).thenReturn(fakeValue);
 *
 * // now fakeValue is returned
 * value = mock.getSomething();
 * </code></pre>
 */

Thus your code should look like:

import org.junit.Test;
import static org.mockito.Mockito.*;
import static org.junit.Assert.*;

public class StockTest {

    public class Stock {
        private final double price;
        private final int quantity;

        Stock(double price, int quantity) {
            this.price = price;
            this.quantity = quantity;
        }

        public double getPrice() {
            return price;
        }

        public int getQuantity() {
            return quantity;
        }

        public double getValue() {
            return getPrice() * getQuantity();
        }
    }

    @Test
    public void getValueTest() {
        Stock stock = mock(Stock.class, withSettings().defaultAnswer(CALLS_REAL_METHODS));
        when(stock.getPrice()).thenReturn(100.00);
        when(stock.getQuantity()).thenReturn(200);
        double value = stock.getValue();

        assertEquals("Stock value not correct", 100.00 * 200, value, .00001);
    }
}

The call to Stock stock = mock(Stock.class); calls org.mockito.Mockito.mock(Class<T>) which looks like this:

 public static <T> T mock(Class<T> classToMock) {
    return mock(classToMock, withSettings().defaultAnswer(RETURNS_DEFAULTS));
}

The docs of the value RETURNS_DEFAULTS tell:

/**
 * The default <code>Answer</code> of every mock <b>if</b> the mock was not stubbed.
 * Typically it just returns some empty value. 
 * <p>
 * {@link Answer} can be used to define the return values of unstubbed invocations. 
 * <p>
 * This implementation first tries the global configuration. 
 * If there is no global configuration then it uses {@link ReturnsEmptyValues} (returns zeros, empty collections, nulls, etc.)
 */

None of the answers above solved my problem so I wanted to include a current solution (as of April 2019) for people using Ubuntu 18.04. This is how I solved the question above...

1. I installed the Android SDK from the website, and put it in this folder: /usr/lib/Android/

2. Search for where the SDK is installed and the version. In my case it was here:

   /usr/lib/Android/Sdk/build-tools/28.0.3

   Note: that I am using version 28.0.3, your version may differ.

3. Add ANDROID_HOME to the environment path. To do this, open /etc/environment with a text editor:

   sudo nano /etc/environment

   Add a line for ANDROID_HOME for your specific version and path. In my case it was:

   ANDROID_HOME="/usr/lib/Android/Sdk/build-tools/28.0.3"

4. Finally, source the updated environment with: source /etc/environment

   Confirm this by trying: echo $ANDROID_HOME in the terminal. You should get the path of your newly created variable.

   One additionally note about sourcing, I did have to restart my computer for the VScode terminal to recognize my changes. After the restart, the environment was set and I haven't had any issues since.

Option 2 is correct: The nested <ul> is a child of the <li> it belongs in.

If you validate, option 1 comes up as an error in html 5 -- credit: user3272456

Correct: <ul> as child of <li>

The proper way to make HTML nested list is with the nested <ul> as a child of the <li> to which it belongs. The nested list should be inside of the <li> element of the list in which it is nested.

<ul>
    <li>Parent/Item
        <ul>
            <li>Child/Subitem
            </li>
        </ul>
    </li>
</ul>

W3C Standard for Nesting Lists

A list item can contain another entire list — this is known as "nesting" a list. It is useful for things like tables of contents, such as the one at the start of this article:

1. Chapter One
   1. Section One
   2. Section Two
   3. Section Three
2. Chapter Two
3. Chapter Three

The key to nesting lists is to remember that the nested list should relate to one specific list item. To reflect that in the code, the nested list is contained inside that list item. The code for the list above looks something like this:

<ol>
  <li>Chapter One
    <ol>
      <li>Section One</li>
      <li>Section Two </li>
      <li>Section Three </li>
    </ol>
  </li>
  <li>Chapter Two</li>
  <li>Chapter Three  </li>
</ol>

Note how the nested list starts after the <li> and the text of the containing list item (“Chapter One”); then ends before the </li> of the containing list item. Nested lists often form the basis for website navigation menus, as they are a good way to define the hierarchical structure of the website.

Theoretically you can nest as many lists as you like, although in practice it can become confusing to nest lists too deeply. For very large lists, you may be better off splitting the content up into several lists with headings instead, or even splitting it up into separate pages.

Been dealing with this issue today using Mongoose 3.5(.2) and none of the answers quite helped me solve this issue. The following code snippet does the trick

Post.find().sort('-posted').find(function (err, posts) {
    // user posts array
});

You can send any standard parameters you need to find() (e.g. where clauses and return fields) but no callback. Without a callback it returns a Query object which you chain sort() on. You need to call find() again (with or without more parameters -- shouldn't need any for efficiency reasons) which will allow you to get the result set in your callback.

As Jason says, you can create a variable of the right type and pass that. You might want to encapsulate it in your own method:

public static DateTime? TryParse(string text)
{
    DateTime date;
    if (DateTime.TryParse(text, out date))
    {
        return date;
    }
    else
    {
        return null;
    }
}

... or if you like the conditional operator:

public static DateTime? TryParse(string text)
{
    DateTime date;
    return DateTime.TryParse(text, out date) ? date : (DateTime?) null;
}

Or in C# 7:

public static DateTime? TryParse(string text) =>
    DateTime.TryParse(text, out var date) ? date : (DateTime?) null;

To handle One-To-Many relationships in Django you need to use ForeignKey.

The documentation on ForeignKey is very comprehensive and should answer all the questions you have:

https://docs.djangoproject.com/en/dev/ref/models/fields/#foreignkey

The current structure in your example allows each Dude to have one number, and each number to belong to multiple Dudes (same with Business).

If you want the reverse relationship, you would need to add two ForeignKey fields to your PhoneNumber model, one to Dude and one to Business. This would allow each number to belong to either one Dude or one Business, and have Dudes and Businesses able to own multiple Numbers. I think this might be what you are after.

class Business(models.Model):
    ...
class Dude(models.Model):
    ...
class PhoneNumber(models.Model):
    dude = models.ForeignKey(Dude)
    business = models.ForeignKey(Business)

Sadly, there's no equivalent to the null coalescing operator that works with DBNull; for that, you need to use the ternary operator:

newValue = (oldValue is DBNull) ? null : oldValue;

In addition to global "editor.rulers" setting, it's also possible to set this on a per-language level.

For example, style guides for Python projects often specify either 79 or 120 characters vs. Git commit messages should be no longer than 50 characters.

So in your settings.json, you'd put:

"[git-commit]": {"editor.rulers": [50]},
"[python]": {
    "editor.rulers": [
        79,
        120
    ]
}

var_dump($obj); 

If you want more info you can use a ReflectionClass:

http://www.phpro.org/manual/language.oop5.reflection.html

Here's the example:

// Test
public void foo() {
    C c = new C();
    A s;
    s = ((A.B)c).get();
    System.out.println(s.getR());
}

// classes
class C {}

class A {
   public class B extends C{
     A get() {return A.this;}
   }
   public String getR() {
     return "This is string";
   }
}

If you want to open it for a range and for a protocol

ufw allow 11200:11299/tcp
ufw allow 11200:11299/udp

Here is how I do it. You will need to get the namespace URL and the element name from your generated code.

new JAXBElement(new QName("http://www.novell.com/role/service","userDN"),
                new String("").getClass(),testDN);

Your function will return the size of a ResultSet, but its cursor will be set after last record, so without rewinding it by calling beforeFirst(), first() or previous() you won't be able to read its rows, and rewinding methods won't work with forward only ResultSet (you'll get the same exception you're getting in your second code fragment).

In SQL Enterprise Management Studio, open up your table, add the column where you want it, and then -- instead of saving the change -- generate the change script. You can see how it's done in SQL.

In short, what others have said is right. SQL Management studio pulls all your data into a temp table, drops the table, recreates it with columns in the right order, and puts the temp table data back in there. There is no simple syntax for adding a column in a specific position.

The right is php_memcache.dll. In my case i was using lib compiled with vc9 instead of vc6 compiler. In apatche error logs i got something like:

PHP Startup: sqlanywhere: Unable to initialize module Module compiled with build ID=API20090626, TS,VC9 PHP compiled with build ID=API20090626, TS,VC6 These options need to match

Check if you have same log and try downloading different dll that are compiled with different compiler.

I've investigated this issue, referring to the LayoutInflater docs and setting up a small sample demonstration project. The following tutorials shows how to dynamically populate a layout using LayoutInflater.

Before we get started see what LayoutInflater.inflate() parameters look like:

• resource: ID for an XML layout resource to load (e.g., R.layout.main_page)
• root: Optional view to be the parent of the generated hierarchy (if attachToRoot is true), or else simply an object that provides a set of LayoutParams values for root of the returned hierarchy (if attachToRoot is false.)

• attachToRoot: Whether the inflated hierarchy should be attached to the root parameter? If false, root is only used to create the correct subclass of LayoutParams for the root view in the XML.

• Returns: The root View of the inflated hierarchy. If root was supplied and attachToRoot is true, this is root; otherwise it is the root of the inflated XML file.

Now for the sample layout and code.

Main layout (main.xml):

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/container"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
</LinearLayout>

Added into this container is a separate TextView, visible as small red square if layout parameters are successfully applied from XML (red.xml):

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="25dp"
    android:layout_height="25dp"
    android:background="#ff0000"
    android:text="red" />

Now LayoutInflater is used with several variations of call parameters

public class InflaterTest extends Activity {

    private View view;

    @Override
    public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);

      setContentView(R.layout.main);
      ViewGroup parent = (ViewGroup) findViewById(R.id.container);

      // result: layout_height=wrap_content layout_width=match_parent
      view = LayoutInflater.from(this).inflate(R.layout.red, null);
      parent.addView(view);

      // result: layout_height=100 layout_width=100
      view = LayoutInflater.from(this).inflate(R.layout.red, null);
      parent.addView(view, 100, 100);

      // result: layout_height=25dp layout_width=25dp
      // view=textView due to attachRoot=false
      view = LayoutInflater.from(this).inflate(R.layout.red, parent, false);
      parent.addView(view);

      // result: layout_height=25dp layout_width=25dp 
      // parent.addView not necessary as this is already done by attachRoot=true
      // view=root due to parent supplied as hierarchy root and attachRoot=true
      view = LayoutInflater.from(this).inflate(R.layout.red, parent, true);
    }
}

The actual results of the parameter variations are documented in the code.

SYNOPSIS: Calling LayoutInflater without specifying root leads to inflate call ignoring the layout parameters from the XML. Calling inflate with root not equal null and attachRoot=true does load the layout parameters, but returns the root object again, which prevents further layout changes to the loaded object (unless you can find it using findViewById()). The calling convention you most likely would like to use is therefore this one:

loadedView = LayoutInflater.from(context)
                .inflate(R.layout.layout_to_load, parent, false);

To help with layout issues, the Layout Inspector is highly recommended.

using javascript:

here input element is used

<input type="text" id="fname" onkeyup="javascript:console.log(window.event.key)">

if you want to use multiline code use curly braces after javascript:

<input type="text" id="fname" onkeyup="javascript:{ console.log(window.event.key); alert('hello'); }">

There are two possible approaches; either you create a unique value and store somewhere along with the creation time, for example in a database, or you put the creation time inside the token so that you can decode it later and see when it was created.

To create a unique token:

string token = Convert.ToBase64String(Guid.NewGuid().ToByteArray());

Basic example of creating a unique token containing a time stamp:

byte[] time = BitConverter.GetBytes(DateTime.UtcNow.ToBinary());
byte[] key = Guid.NewGuid().ToByteArray();
string token = Convert.ToBase64String(time.Concat(key).ToArray());

To decode the token to get the creation time:

byte[] data = Convert.FromBase64String(token);
DateTime when = DateTime.FromBinary(BitConverter.ToInt64(data, 0));
if (when < DateTime.UtcNow.AddHours(-24)) {
  // too old
}

Note: If you need the token with the time stamp to be secure, you need to encrypt it. Otherwise a user could figure out what it contains and create a false token.

mongo-db is likely not a great choice for new developers.
On the other hand mongoose as an ORM (Object Relational Mapping) can be a better choice for the new-bies.

You should be referencing it as localhost. Like this:

<img src="http:\\localhost\site\img\mypicture.jpg"/>

The only way I have 100% consistently been able to avoid this flex-direction column bug is to use a min-width media query to assign a max-width to the child element on desktop sized screens.

.parent {
    display: flex;
    flex-direction: column;
}

//a media query targeting desktop sort of sized screens
@media screen and (min-width: 980px) {
    .child {
        display: block;
        max-width: 500px;//maximimum width of the element on a desktop sized screen
    }
}

You will need to set naturally inline child elements (eg. <span> or <a>) to something other than inline (mainly display:block or display:inline-block) for the fix to work.

Kotlin:

var ver: String = packageManager.getPackageInfo(packageName, 0).versionName

As I understand your question..

From Java List class you have to methods add(E e) and get(int position).

add(E e)

Appends the specified element to the end of this list (optional operation).

get(int index)

Returns the element at the specified position in this list.

Example:

List<String> myString = new ArrayList<String>();

// How you add your data in string list
myString.add("Test 1");
myString.add("Test 2");
myString.add("Test 3");
myString.add("Test 4");

// retrieving data from string list array in for loop
for (int i=0;i < myString.size();i++)
{
  Log.i("Value of element "+i,myString.get(i));
}

But efficient way to iterate thru loop

for (String value : myString)
{
  Log.i("Value of element ",value);
}

You cannot call orElse after ifPresent, the reason is, orElse is called on an optiional but ifPresent returns void. So the best approach to achieve is ifPresentOrElse. It could be like this:

op.ifPresentOrElse( 
            (value) 
                -> { System.out.println( 
                         "Value is present, its: "
                         + value); }, 
            () 
                -> { System.out.println( 
                         "Value is empty"); }); 

>>> from datetime import datetime

>>>  a = datetime.now()

# wait a bit 
>>> b = datetime.now()

>>> d = b - a # yields a timedelta object
>>> d.seconds
7

(7 will be whatever amount of time you waited a bit above)

I find datetime.datetime to be fairly useful, so if there's a complicated or awkward scenario that you've encountered, please let us know.

EDIT: Thanks to @WoLpH for pointing out that one is not always necessarily looking to refresh so frequently that the datetimes will be close together. By accounting for the days in the delta, you can handle longer timestamp discrepancies:

>>> a = datetime(2010, 12, 5)
>>> b = datetime(2010, 12, 7)
>>> d = b - a
>>> d.seconds
0
>>> d.days
2
>>> d.seconds + d.days * 86400
172800

If you plan to build a full functional applications with more than a handful of features, I will suggest to jump right to using Eclipse RCP as the framework.

If your application won't grow too big or your requirements are just too unique to be handled by a normal business framework, you can safely jump with Swing.

At the end of the day, I'd suggest you to try both technologies to find the one suit you better. Like Netbeans vs Eclipse vs IntelliJ, there is no the absolute correct answer here and both frameworks have their own drawbacks.

Pro Swing:

• more experts
• more Java-like (almost no public field, no need to dispose on resource)

Pro SWT:

• more OS native
• faster

You are looking for the re.sub function.

import re
s = "Example String"
replaced = re.sub('[ES]', 'a', s)
print replaced 

will print axample atring

You can get another validation on this tutorial : http://twitterbootstrap.org/bootstrap-form-validation

They use JQuery validation.

jquery.validate.js

jquery.validate.min.js

jquery-1.7.1.min.js

And you'll get the source code there.

happy coding.

You can't.

Well, of course you could, however an int (System.Int32) is not big enough to hold every possible decimal value.

That means if you cast a decimal that's larger than int.MaxValue you will overflow, and if the decimal is smaller than int.MinValue, it will underflow.

What happens when you under/overflow? One of two things. If your build is unchecked (i.e., the CLR doesn't care if you do), your application will continue after the value over/underflows, but the value in the int will not be what you expected. This can lead to intermittent bugs and may be hard to fix. You'll end up your application in an unknown state which may result in your application corrupting whatever important data its working on. Not good.

If your assembly is checked (properties->build->advanced->check for arithmetic overflow/underflow or the /checked compiler option), your code will throw an exception when an under/overflow occurs. This is probably better than not; however the default for assemblies is not to check for over/underflow.

The real question is "what are you trying to do?" Without knowing your requirements, nobody can tell you what you should do in this case, other than the obvious: DON'T DO IT.

If you specifically do NOT care, the answers here are valid. However, you should communicate your understanding that an overflow may occur and that it doesn't matter by wrapping your cast code in an unchecked block

unchecked
{
  // do your conversions that may underflow/overflow here
}

That way people coming behind you understand you don't care, and if in the future someone changes your builds to /checked, your code won't break unexpectedly.

If all you want to do is drop the fractional portion of the number, leaving the integral part, you can use Math.Truncate.

decimal actual = 10.5M;
decimal expected = 10M;
Assert.AreEqual(expected, Math.Truncate(actual));

it is working in google chrome when you add !important attribute to background image make sure you add attribute first and try again, you can do it like that

    .inputbg {
background: url('inputbg.png') !important;  

}

You can try specifying the BaseException type explicitly. However, this will only catch derivatives of BaseException. While this includes all implementation-provided exceptions, it is also possibly to raise arbitrary old-style classes.

try:
  do_something()
except BaseException, e:
  logger.error('Failed to do something: ' + str(e))

When you create the tsconfig.json file by tsc --init, then it comments the input and output file directory. So this is the root cause of the error.

To get around the problem, uncomment these two lines:

"outDir": "./", 
"rootDir": "./", 

Initially it would look like above after un-commenting.

But all my .ts scripts were inside src folder. So I have specified /src.

"outDir": "./scripts", 
"rootDir": "./src", 

Please note that you need to specify the location of your .ts scripts in rootDir.

Here is a CoffeeScript solution.

I was looking for the same solution and found seomething very intersting from this answer: Rejecting promises with multiple arguments (like $http) in AngularJS

the answer of this guy Florian

promise = deferred.promise

promise.success = (fn) ->
  promise.then (data) ->
   fn(data.payload, data.status, {additional: 42})
  return promise

promise.error = (fn) ->
  promise.then null, (err) ->
    fn(err)
  return promise

return promise 

And to use it:

service.get().success (arg1, arg2, arg3) ->
    # => arg1 is data.payload, arg2 is data.status, arg3 is the additional object
service.get().error (err) ->
    # => err

In extremely non-technical terms, it may mean that you forgot to put "ejb:" or "jdbc:" or something at the very beginning of the URI you are trying to connect.

The way I load static images and fonts:

module: {
    rules: [
      ....

      {
        test: /\.(jpe?g|png|gif|svg)$/i,
        /* Exclude fonts while working with images, e.g. .svg can be both image or font. */
        exclude: path.resolve(__dirname, '../src/assets/fonts'),
        use: [{
          loader: 'file-loader',
          options: {
            name: '[name].[ext]',
            outputPath: 'images/'
          }
        }]
      },
      {
        test: /\.(woff(2)?|ttf|eot|svg|otf)(\?v=\d+\.\d+\.\d+)?$/,
        /* Exclude images while working with fonts, e.g. .svg can be both image or font. */
        exclude: path.resolve(__dirname, '../src/assets/images'),
        use: [{
          loader: 'file-loader',
          options: {
            name: '[name].[ext]',
            outputPath: 'fonts/'
          },
        }
    ]
}

Don't forget to install file-loader to have that working.

Since this page is the number 1 result for the google search "c++ floating point exception", I want to add another thing that can cause such a problem: use of undefined variables.

   <input type="text" id="text" name="search">
<table id="table_data">
        <tr class="listR"><td>PHP</td></tr>
        <tr class="listR"><td>MySql</td></tr>
        <tr class="listR"><td>AJAX</td></tr>
        <tr class="listR"><td>jQuery</td></tr>
        <tr class="listR"><td>JavaScript</td></tr>
        <tr class="listR"><td>HTML</td></tr>
        <tr class="listR"><td>CSS</td></tr>
        <tr class="listR"><td>CSS3</td></tr>
</table>

$("#textbox").on('keyup',function(){
        var f = $(this).val();
      $("#table_data tr.listR").each(function(){
            if ($(this).text().search(new RegExp(f, "i")) < 0) {
                $(this).fadeOut();
             } else {
                 $(this).show();
            }
        });
    });

Demo You can perform by search() method with use RegExp matching text

graphics.h appears to something once bundled with Borland and/or Turbo C++, in the 90's.

http://www.daniweb.com/software-development/cpp/threads/17709/88149#post88149

It's unlikely that you will find any support for that file with modern compiler. For other graphics libraries check the list of "related" questions (questions related to this one). E.g., "A Simple, 2d cross-platform graphics library for c or c++?".

Warning! Your SQL isn't a good idea, because it will select all rows (no WHERE clause assumes "WHERE 1"!) and clog your application if you have a large number of rows. (What's the point of selecting 1,000 rows when 1 will do?) So instead, when selecting only one row, make sure you specify the LIMIT clause:

$sql = "SELECT id FROM games LIMIT 1";  // Select ONLY one, instead of all
$result = $db->query($sql);
$row = $result->fetch_assoc();
echo 'Game ID: '.$row['id'];

This difference requires MySQL to select only the first matching record, so ordering the table is important or you ought to use a WHERE clause. However, it's a whole lot less memory and time to find that one record, than to get every record and output row number one.

Simply...

    preg_match('/(?:http[s]*\:\/\/)*(.*?)\.(?=[^\/]*\..{2,5})/i', $url, $match);

Just read $match[1]

Working example

It works perfectly with this list of urls

$url = array(
    'http://www.domain.com', // www
    'http://domain.com', // --nothing--
    'https://domain.com', // --nothing--
    'www.domain.com', // www
    'domain.com', // --nothing--
    'www.domain.com/some/path', // www
    'http://sub.domain.com/domain.com', // sub
    '???????????????.????????.ua', // ??????????????? ;)
    '????????.ua', // --nothing--
    'http://sub-domain.domain.net/domain.net', // sub-domain
    'sub-domain.third-Level_DomaIN.domain.uk.co/domain.net' // sub-domain
);

foreach ($url as $u) {
    preg_match('/(?:http[s]*\:\/\/)*(.*?)\.(?=[^\/]*\..{2,5})/i', $u, $match);
    var_dump($match);
}

On Mac OS use

find -E packages  -regex ".*\.(jpg|gif|png|jpeg)"

The generic view of a loop is

for (initialization; condition; increment-decrement){}

The first part initializes the code. The second part is the condition that will continue to run the loop as long as it is true. The last part is what will be run after each iteration of the loop. The last part is typically used to increment or decrement a counter, but it doesn't have to.

Use .push:

items.push({'id':5});

The difference is that, for example, a

List<HashMap<String,String>>

is a

List<? extends Map<String,String>>

but not a

List<Map<String,String>>

So:

void withWilds( List<? extends Map<String,String>> foo ){}
void noWilds( List<Map<String,String>> foo ){}

void main( String[] args ){
    List<HashMap<String,String>> myMap;

    withWilds( myMap ); // Works
    noWilds( myMap ); // Compiler error
}

You would think a List of HashMaps should be a List of Maps, but there's a good reason why it isn't:

Suppose you could do:

List<HashMap<String,String>> hashMaps = new ArrayList<HashMap<String,String>>();

List<Map<String,String>> maps = hashMaps; // Won't compile,
                                          // but imagine that it could

Map<String,String> aMap = Collections.singletonMap("foo","bar"); // Not a HashMap

maps.add( aMap ); // Perfectly legal (adding a Map to a List of Maps)

// But maps and hashMaps are the same object, so this should be the same as

hashMaps.add( aMap ); // Should be illegal (aMap is not a HashMap)

So this is why a List of HashMaps shouldn't be a List of Maps.

aView.center = CGPointMake(150, 150); // set center

or

aView.frame = CGRectMake( 100, 200, aView.frame.size.width, aView.frame.size.height ); // set new position exactly

or

aView.frame = CGRectOffset( aView.frame, 10, 10 ); // offset by an amount

Edit:

I didn't compile this yet, but it should work:

#define CGRectSetPos( r, x, y ) CGRectMake( x, y, r.size.width, r.size.height )

aView.frame = CGRectSetPos( aView.frame, 100, 200 );

Short and sweet, no additional modules needed:

my $toDate = `date +%m/%d/%Y" "%l:%M:%S" "%p`;

Output for example would be: 04/25/2017 9:30:33 AM

You just need to change some files. This works for me.

Global.ascx

public class WebApiApplication : System.Web.HttpApplication {
    protected void Application_Start()
    {
        WebApiConfig.Register(GlobalConfiguration.Configuration);
    } }

WebApiConfig.cs

All the requests has to call this code.

public static class WebApiConfig {
    public static void Register(HttpConfiguration config)
    {
        EnableCrossSiteRequests(config);
        AddRoutes(config);
    }

    private static void AddRoutes(HttpConfiguration config)
    {
        config.Routes.MapHttpRoute(
            name: "Default",
            routeTemplate: "api/{controller}/"
        );
    }

    private static void EnableCrossSiteRequests(HttpConfiguration config)
    {
        var cors = new EnableCorsAttribute(
            origins: "*", 
            headers: "*", 
            methods: "*");
        config.EnableCors(cors);
    } }

Some Controller

Nothing to change.

Web.config

You need to add handlers in your web.config

<configuration> 
  <system.webServer>
    <handlers>
      <remove name="ExtensionlessUrlHandler-Integrated-4.0" />
      <remove name="OPTIONSVerbHandler" />
      <remove name="TRACEVerbHandler" />
      <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
    </handlers>   
  </system.webServer> 
</configuration>

Update

Apple has clarified that slicing occurs independent of enabling bitcode. I've observed this in practice as well where a non-bitcode enabled app will only be downloaded as the architecture appropriate for the target device.

Original

More specifically:

Bitcode. Archive your app for submission to the App Store in an intermediate representation, which is compiled into 64- or 32-bit executables for the target devices when delivered.

Slicing. Artwork incorporated into the Asset Catalog and tagged for a platform allows the App Store to deliver only what is needed for installation.

The way I read this, if you support bitcode, downloaders of your app will only get the compiled architecture needed for their own device.

In my case, I found out it was division by zero.

(Get-WmiObject -Class Win32_NetworkAdapterConfiguration | where {$_.DefaultIPGateway -ne $null}).IPAddress | select-object -first 1

1. First you need to add all untracked files. Use this command line:

   git add *

2. Then commit using this command line :

   git commit -a

You can access the groups simply through the groups attribute on User.

from django.contrib.auth.models import User, Group

group = Group(name = "Editor")
group.save()                    # save this new group for this example
user = User.objects.get(pk = 1) # assuming, there is one initial user 
user.groups.add(group)          # user is now in the "Editor" group

then user.groups.all() returns [<Group: Editor>].

Alternatively, and more directly, you can check if a a user is in a group by:

if django_user.groups.filter(name = groupname).exists():

    ...

Note that groupname can also be the actual Django Group object.

Use the rename script this way:

$ rename 's/^/PRE_/' *

There are no problems with metacharacters or whitespace in filenames.

Data as JSON:

data = [
       {
       "rank":"9",
       "content":"Alon",
       "UID":"5"
       },
       {
       "rank":"6",
       "content":"Tala",
       "UID":"6"
       }
       ]

You can use jQuery to iterate over JSON and create tables dynamically:

num_rows = data.length;
num_cols = size_of_array(data[0]);

table_id = 'my_table';
table = $("<table id=" + table_id + "></table>");

header = $("<tr class='table_header'></tr>");
$.each(Object.keys(data[0]), function(ind_header, val_header) {
col = $("<td>" + val_header + "</td>");
header.append(col);
})
table.append(header);

$.each(data, function(ind_row, val) {
row = $("<tr></tr>");
$.each(val, function(ind_cell, val_cell) {
col = $("<td>" + val_cell + "</td>");
row.append(col);
})
table.append(row);
})

Here is the size_of_array function:

function size_of_array(obj) {
    size = Object.keys(obj).length;
    return(size)
    };

You can also add styling if needed:

$('.' + content['this_class']).children('canvas').remove();
$('.' + content['this_class']).append(table);
$('#' + table_id).css('width', '100%').css('border', '1px solid black').css('text-align', 'center').css('border-collapse', 'collapse');
$('#' + table_id + ' td').css('border', '1px solid black');

Result:

The exception is caused by disabled Download Manager. And there is no way to activate/deactivate Download Manager directly, since it's system application and we don't have access to it.

Only alternative way is redirect user to settings of Download Manager Application.

try {
     //Open the specific App Info page:
     Intent intent = new Intent(android.provider.Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
     intent.setData(Uri.parse("package:" + "com.android.providers.downloads"));
     startActivity(intent);

} catch ( ActivityNotFoundException e ) {
     e.printStackTrace();

     //Open the generic Apps page:
     Intent intent = new Intent(android.provider.Settings.ACTION_MANAGE_APPLICATIONS_SETTINGS);
     startActivity(intent);
}

Use a regular for loop and format the index to be used in the selector.

var array = [];
for (var i = 0; i < 4; i++) {
    var selector = '' + i;
    if (selector.length == 1)
        selector = '0' + selector;
    selector = '#event' + selector;
    array.push($(selector, response).html());
}

Read the FAQ! Holding C++ data in C can be risky.

In C++, a pointer to an object can be converted to void * without any casts. But it's not true the other way round. You'd need a static_cast to get the original pointer back.

Updated answer

When I originally answered this question in 2014, there was no requirement to not scale the image up in the case of a small image. (The question was edited in 2015.) If you have such a requirement, you will indeed need to compare the image's size to that of the imageView and use either UIViewContentModeCenter (in the case of an image smaller than the imageView) or UIViewContentModeScaleAspectFit in all other cases.

Original answer

Setting the imageView's contentMode to UIViewContentModeScaleAspectFit was enough for me. It seems to center the images as well. I'm not sure why others are using logic based on the image. See also this question: iOS aspect fit and center

Use either JavaScript or jQuery for this.

Using JavaScript

<script>
function val() {
    d = document.getElementById("select_id").value;
    alert(d);
}
</script>

<select onchange="val()" id="select_id">

Using jQuery

$('#select_id').change(function(){
    alert($(this).val());
})

From ScottGu's blog:

Starting with the ASP.NET MVC 3 Beta release, you can now add a file called _ViewStart.cshtml (or _ViewStart.vbhtml for VB) underneath the \Views folder of your project:

The _ViewStart file can be used to define common view code that you want to execute at the start of each View’s rendering. For example, we could write code within our _ViewStart.cshtml file to programmatically set the Layout property for each View to be the SiteLayout.cshtml file by default:

Because this code executes at the start of each View, we no longer need to explicitly set the Layout in any of our individual view files (except if we wanted to override the default value above).

Important: Because the _ViewStart.cshtml allows us to write code, we can optionally make our Layout selection logic richer than just a basic property set. For example: we could vary the Layout template that we use depending on what type of device is accessing the site – and have a phone or tablet optimized layout for those devices, and a desktop optimized layout for PCs/Laptops. Or if we were building a CMS system or common shared app that is used across multiple customers we could select different layouts to use depending on the customer (or their role) when accessing the site.

This enables a lot of UI flexibility. It also allows you to more easily write view logic once, and avoid repeating it in multiple places.

Also see this.

In a more general sense this ability of MVC framework to "know" about _Viewstart.cshtml is called "Coding by convention".

Convention over configuration (also known as coding by convention) is a software design paradigm which seeks to decrease the number of decisions that developers need to make, gaining simplicity, but not necessarily losing flexibility. The phrase essentially means a developer only needs to specify unconventional aspects of the application. For example, if there's a class Sale in the model, the corresponding table in the database is called “sales” by default. It is only if one deviates from this convention, such as calling the table “products_sold”, that one needs to write code regarding these names.

Wikipedia

There's no magic to it. Its just been written into the core codebase of the MVC framework and is therefore something that MVC "knows" about. That why you don't find it in the .config files or elsewhere; it's actually in the MVC code. You can however override to alter or null out these conventions.

If your environment is using both Guice and Spring and using the constructor @Inject, for example, with Play Framework, you will also run into this issue if you have mistakenly auto-completed the import with an incorrect choice of:

import com.google.inject.Inject;

Then you get the same missing default constructor error even though the rest of your source with @Inject looks exactly the same way as other working components in your project and compile without an error.

Correct that with:

import javax.inject.Inject;

Do not write a default constructor with construction time injection.

NSArray *directoryPath = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,YES);
NSString *imagePath =  [directoryPath objectAtIndex:0];
//If you have superate folder
imagePath= [imagePath stringByAppendingPathComponent:@"ImagesFolder"];//Get docs dir path with folder name
_imageName = [_imageName stringByAppendingString:@".jpg"];//Assign image name
imagePath= [imagePath stringByAppendingPathComponent:_imageName];
NSLog(@"%@", imagePath);

//Method 1:
BOOL file = [[NSFileManager defaultManager] fileExistsAtPath: imagePath];
if (file == NO){
    NSLog("File not exist");
} else {
    NSLog("File exist");
}

//Method 2:
NSData *data = [NSData dataWithContentsOfFile:imagePath];
UIImage *image = [UIImage imageWithData:data];
if (!(image == nil)) {//Check image exist or not
    cell.photoImageView.image = image;//Display image
}

And for those of you using an anonymous expression:

await Task.Run(async () =>
{
   SQLLiteUtils slu = new SQLiteUtils();
   await slu.DeleteGroupAsync(groupname);
});

Ternary operator works because the first part of it returns a Boolean value. In your case, jQuery's css method returns the jQuery object, thus not valid for ternary operation.

If you want to set an html content containg script tag to iframe, you have access to the iframe you created with:

$(iframeElement).contentWindow.document

so you can set innerHTML of any element in this.

But, for script tag, you should create and append an script tag, like this:

Was having this issue testing long doubles, and alas, I came across a fix! You have to compile your project with -D__USE_MINGW_ANSI_STDIO:

Jason Huntley@centurian /home/developer/dependencies/Python-2.7.3/test $ gcc main.c

Jason Huntley@centurian /home/developer/dependencies/Python-2.7.3/test $ a.exe c=0.000000

Jason Huntley@centurian /home/developer/dependencies/Python-2.7.3/test $ gcc main.c -D__USE_MINGW_ANSI_STDIO

Jason Huntley@centurian /home/developer/dependencies/Python-2.7.3/test $ a.exe c=42.000000

Code:

Jason Huntley@centurian /home/developer/dependencies/Python-2.7.3/test
$ cat main.c
#include <stdio.h>

int main(int argc, char **argv)
{
   long double c=42;

   c/3;

   printf("c=%Lf\n",c);

   return 0;
}

I have seen various answers which say when I uninstalled this or that it worked. I think that the uninstall is probably just sorting out an issue in the registry, rather it being an issue with the particular application that is being uninstalled.

I have also seen cases of people saying kill the RDP task but I don't have that and I still have the error.

I have seen cases of people saying clear the clipboard in Excel, but that doesn't work for me - nor does changing the settings in the Clipboard.

I believe that the issue is that an application has a lock on the clipboard and that application is not releasing it. The clipboard is a shared resource, so that implies that each application has to get a lock on it before changing it and then release the lock once it has completed the change, however, it looks like sometimes the lock is not released.

I found that the following cured it. Close down all MS applications including IE and Outlook. Check Task Manager processes to make sure that they are all gone.

Then restart the application where you had the Copy and Paste issue and it will probably then work.

The heap part gets worse, my friends. UTF-16 isn't guaranteed to be limited to 16 bits and can expand to 32

I took Eugen Rieck's answer and worked with it. My code adds the following:

1. ps ax includes grep, so I excluded it with grep -Eiv 'grep'
2. Added a few ifs and echoes to make it human-readable.

I've created a file, named it killserver, here it goes:

#!/bin/bash
PROCESS_TO_KILL=bin/node
PROCESS_LIST=`ps ax | grep -Ei ${PROCESS_TO_KILL} | grep -Eiv 'grep' | awk ' { print $1;}'`
KILLED=
for KILLPID in $PROCESS_LIST; do
  if [ ! -z $KILLPID ];then
    kill -9 $KILLPID
    echo "Killed PID ${KILLPID}"
    KILLED=yes
  fi
done

if [ -z $KILLED ];then
    echo "Didn't kill anything"
fi

Results

<input id="checkboxId" type="checkbox" checked="" name="copyNewAddrToBilling">

and then in JavaScript:

document.getElementById("checkboxId").checked = false;

CSS will skip over style declarations it doesn't understand. Mozilla-based browsers will not understand -webkit-prefixed declarations, and WebKit-based browsers will not understand -moz-prefixed declarations.

Because of this, we can simply declare width twice:

elem {
    width: 100%;
    width: -moz-available;          /* WebKit-based browsers will ignore this. */
    width: -webkit-fill-available;  /* Mozilla-based browsers will ignore this. */
    width: fill-available;
}

The width: 100% declared at the start will be used by browsers which ignore both the -moz and -webkit-prefixed declarations or do not support -moz-available or -webkit-fill-available.

Last column in your input file must have some data in it (be it space or char, but not null). I guess, 1st record contains null after last ',' which sqlldr won't recognize unless specifically asked to recognize nulls using TRAILING NULLCOLS option. Alternatively, if you don't want to use TRAILING NULLCOLS, you will have to take care of those NULLs before you pass the file to sqlldr. Hope this helps

Both @Autowired (or @Inject) and @Resource work equally well. But there is a conceptual difference or a difference in the meaning

• @Resource means get me a known resource by name. The name is extracted from the name of the annotated setter or field, or it is taken from the name-Parameter.
• @Inject or @Autowired try to wire in a suitable other component by type.

So, basically these are two quite distinct concepts. Unfortunately the Spring-Implementation of @Resource has a built-in fallback, which kicks in when resolution by-name fails. In this case, it falls back to the @Autowired-kind resolution by-type. While this fallback is convenient, IMHO it causes a lot of confusion, because people are unaware of the conceptual difference and tend to use @Resource for type-based autowiring.

Following Peter Hauge's comment, upon running docker network ls I saw (among other lines) the following:

NETWORK ID          NAME                                    DRIVER              SCOPE
dc6a83d13f44        bridge                                  bridge              local
ea98225c7754        docker_gwbridge                         bridge              local
107dcd8aa889        host                                    host                local

The line with NAME and DRIVER as both host seems to be what he is referring to with "networks already created on your host". So, following https://gist.github.com/bastman/5b57ddb3c11942094f8d0a97d461b430, I ran the command

docker network rm $(docker network ls | grep "bridge" | awk '/ / { print $1 }')

Now docker-compose up works (although newnym.py produces an error).

$('.modal').on('shown.bs.modal',function(){      //correct here use 'shown.bs.modal' event which comes in bootstrap3
  $(this).find('iframe').attr('src','http://www.google.com')
})

As shown above use 'shown.bs.modal' event which comes in bootstrap 3.

EDIT :-

and just try to open some other url from iframe other than google.com ,it will not allow you to open google.com due to some security threats.

The reason for this is, that Google is sending an "X-Frame-Options: SAMEORIGIN" response header. This option prevents the browser from displaying iFrames that are not hosted on the same domain as the parent page.

One possibility:

myArray = myArray.filter(function( obj ) {
    return obj.field !== 'money';
});

Please note that filter creates a new array. Any other variables referring to the original array would not get the filtered data although you update your original variable myArray with the new reference. Use with caution.

The way we have done it was using Broadcasts:

1. Send the broadcast every time the user changes language
2. Register the broadcast receiver in the AppActivity.onCreate() and unregister in AppActivity.onDestroy()
3. In BroadcastReceiver.onReceive() just restart the activity.

AppActivity is the parent activity which all other activities subclass.

Below is the snippet from my code, not tested outside the project, but should give you a nice idea.

When the user changes the language

sendBroadcast(new Intent("Language.changed"));

And in the parent activity

public class AppActivity extends Activity {

    /**
     * The receiver that will handle the change of the language.
     */
    private BroadcastReceiver mLangaugeChangedReceiver;

    @Override
    protected void onCreate(final Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // ...
        // Other code here
        // ...

        // Define receiver
        mLangaugeChangedReceiver = new BroadcastReceiver() {

            @Override
            public void onReceive(final Context context, final Intent intent) {
                startActivity(getIntent());
                finish();
            }
        };

        // Register receiver
        registerReceiver(mLangaugeChangedReceiver, new IntentFilter("Language.changed"));
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();

        // ...
        // Other cleanup code here
        // ...

        // Unregister receiver
        if (mLangaugeChangedReceiver != null) {
            try {
                unregisterReceiver(mLangaugeChangedReceiver);
                mLangaugeChangedReceiver = null;
            } catch (final Exception e) {}
        }
    }
}

This will also refresh the activity which changed the language (if it subclasses the above activity).

This will make you lose any data, but if it is important you should already have taken care of this using Actvity.onSaveInstanceState() and Actvity.onRestoreInstanceState() (or similar).

Let me know your thoughts about this.

Cheers!

The original post might have been true back in 2009, but now it is actually incorrect now, and no linking is even required for the stylesheet as I see mentioned in some of the other responses. Rails will now do this for you by default.

• Place any new sheet .css (or other) in app/assets/stylesheets
• Test your server with rails-root/scripts/rails server and you'll see the link is added by rails itself.

You can test this with a path in your browser like testserverpath:3000/assets/filename_to_test.css?body=1

None of the above solutions worked for me, but simply stopping and running "ng serve" again.

Best solution is posted at phpjs.org implementation of PHP function htmlentities

The format is htmlentities(string, quote_style, charset, double_encode) Full documentation on the PHP function which is identical can be read here

There is a really simple way to do this using a more recent version of SQL Server Management Studio (I'm using 18.4)

1. Open the "Connect to Server" dialog
2. Click the "Server Name" dropdown so it opens
3. Press the down arrow on your keyboard to highlight a server name
4. Press delete on your keyboard

Login gone! No messing around with dlls or bin files.

I prefer to store image paths in the DB and images on the filesystem (with rsync between servers to keep everything reasonably current).

However, some of the content-management-system stuff I do needs the images in the CMS for several reasons- visibility control (so the asset is held back until the press release goes out), versioning, reformatting (some CMS's will dynamically resize for thumbnails )and ease of use for linking the images into the WYSIWYG pages.

So the rule of thumb for me is to always stash application stuff on the filesystem, unless it's CMS driven.

I think you want this syntax:

ALTER TABLE tb_TableName  
add constraint cnt_Record_Status Default '' for Record_Status

Based on some of your comments, I am going to guess that you might already have null values in your table which is causing the alter of the column to not null to fail. If that is the case, then you should run an UPDATE first. Your script will be:

update tb_TableName
set Record_Status  = ''
where Record_Status is null

ALTER TABLE tb_TableName
ALTER COLUMN Record_Status VARCHAR(20) NOT NULL

ALTER TABLE tb_TableName
ADD CONSTRAINT DEF_Name DEFAULT '' FOR Record_Status

See SQL Fiddle with demo

You can also try this.

 $(document).ready(function () {
            var url = "@(Html.Raw(Url.Action("ActionName", "ControllerName")))";
            $("#PartialViewDivId").load(url);
        setInterval(function () {
            var url = "@(Html.Raw(Url.Action("ActionName", "ControllerName")))";
            $("#PartialViewDivId").load(url);
        }, 30000); //Refreshes every 30 seconds

        $.ajaxSetup({ cache: false });  //Turn off caching
    });

It makes an initial call to load the div, and then subsequent calls are on a 30 second interval.

In the controller section you can update the object and pass the object to the partial view.

public class ControllerName: Controller
{
    public ActionResult ActionName()
    {
        .
        .   // code for update object
        .
        return PartialView("PartialViewName", updatedObject);
    }
}

I think the best way is by using TableAdapters rather than using Commands objects, its Update method sends all changes mades (Updates,Inserts and Deletes) inside a Dataset or DataTable straight TO the database. Usually when using a DataGridView you bind to a BindingSource which lets you interact with a DataSource such as Datatables or Datasets.

If you work like this, then on your bounded DataGridView you can just do:

this.customersBindingSource.EndEdit();
this.myTableAdapter.Update(this.myDataSet.Customers);

The 'customersBindingSource' is the DataSource of the DataGridView.

The adapter's Update method will update a single data table and execute the correct command (INSERT, UPDATE, or DELETE) based on the RowState of each data row in the table.

From: https://msdn.microsoft.com/en-us/library/ms171933.aspx

So any changes made inside the DatagridView will be reflected on the Database when using the Update method.

More about TableAdapters: https://msdn.microsoft.com/en-us/library/bz9tthwx.aspx

var fileName = req.files.upload.name;

var arr = fileName.split('.');

var extension = arr[length-1];

I know it's an old post but I had the same issue today, what I did is simple : changing my script that send my playbook from my local host to the server, before sending it with maven command, I did this :

cat common_vars.yml > vars.yml
cat snapshot_vars.yml >> vars.yml
# or 
#cat release_vars.yml >> vars.yml
mvn ....

If you want to call your activity, just use this . You use the getActivity method when you are inside a fragment.

You can also do this in addition

import re
string='24234ww'
val = re.search('[a-zA-Z]+',string) 
val[0].isalpha() # returns True if the variable is an alphabet
print(val[0]) # this will print the first instance of the matching value

Also note that if variable val returns None. That means the search did not find a match

You need to edit your my.cnf file and make sure you have the port set as in the following line:

port = 3360

Then restart your MySQL service and you should be good to go. There is no query you can run to make this change because the port is not a dynamic variable (q.v. here for MySQL documentation showing a table of all system variables).

data attributes are commonly used for a variety of interactions. Typically via javascript. They do not affect anything regarding site behavior and stand as a convenient method to pass data for whatever purpose needed. Here is an article that may clear things up:

http://ejohn.org/blog/html-5-data-attributes/

You can create a data attribute by prefixing data- to any standard attribute safe string (alphanumeric with no spaces or special characters). For example, data-id or in this case data-reactid

Markdown gets converted into HTML/XHMTL.

John Gruber created the Markdown language in 2004 in collaboration with Aaron Swartz on the syntax, with the goal of enabling people to write using an easy-to-read, easy-to-write plain text format, and optionally convert it to structurally valid HTML (or XHTML).

HTML is completely based on using   for adding extra spaces if it doesn't externally define/use JavaScript or CSS for elements.

Markdown is a lightweight markup language with plain text formatting syntax. It is designed so that it can be converted to HTML and many other formats using a tool by the same name.

If you want to use »

1. only one space » either use   or just hit Spacebar (2nd one is good choice in this case)

2. more than one space » use  +space (for 2 consecutive spaces)

eg. If you want to add 10 spaces contiguously then you should use

                   

 space space space space space

instead of using 10   one after one as the below one

You just need to put -y with the install command.

Another way to install python3 is using wget. Below are the steps for installation.

wget http://www.python.org/ftp/python/3.3.5/Python-3.3.5.tar.xz
tar xJf ./Python-3.3.5.tar.xz
cd ./Python-3.3.5
./configure --prefix=/opt/python3.3
make && sudo make install

Also,one can create an alias for the same using

echo 'alias py="/opt/python3.3/bin/python3.3"' >> ~/.bashrc

Now open a new terminal and type py and press Enter.

Did you set proper charset in the HTML Head section?

<meta http-equiv="Content-Type" content="text/html;charset=UTF-8">

or you can set content type in your php script using -

   header( 'Content-Type: text/html; charset=utf-8' ); 

There are already some discussions here on StackOverflow - please have a look

How to make MySQL handle UTF-8 properly setting utf8 with mysql through php

PHP/MySQL with encoding problems

So what i want to know is how can i directly store ???????? into my database and fetch it and display in my webpage using PHP.

I am not sure what you mean by "directly storing in the database" .. did you mean entering data using PhpMyAdmin or any other similar tool? If yes, I have tried using PhpMyAdmin to input unicode data, so it has worked fine for me - You could try inputting data using phpmyadmin and retrieve it using a php script to confirm. If you need to submit data via a Php script just set the NAMES and CHARACTER SET when you create mysql connection, before execute insert queries, and when you select data. Have a look at the above posts to find the syntax. Hope it helps.

** UPDATE ** Just fixed some typos etc

All else being equal, the best solution is one that clearly expresses your intent. So:

int totalSeconds = 453;
int minutes = totalSeconds / 60;
int remainingSeconds = totalSeconds % 60;

is probably the best of the three options you presented. As noted in other answers however, the div method will calculate both values for you at once.

"How to find all a which are children of <li class=test> but not any others?"

Given the HTML below (I added another <a> to show te difference between select and select_one):

<div>
  <li class="test">
    <a>link1</a>
    <ul>
      <li>
        <a>link2</a>
      </li>
    </ul>
    <a>link3</a>
  </li>
</div>

The solution is to use child combinator (>) that is placed between two CSS selectors:

>>> soup.select('li.test > a')
[<a>link1</a>, <a>link3</a>]

In case you want to find only the first child:

>>> soup.select_one('li.test > a')
<a>link1</a>

If you are willing to insert non-semantic nodes into your document, you can do this in a CSS-only IE-compatible manner by wrapping your divs in fake A tags.

<style type="text/css">
  .content {
    background: #ccc;
  }

  .fakeLink { /* This is to make the link not look like one */
    cursor: default;
    text-decoration: none;
    color: #000;
  }

  a.fakeLink:hover .content {
    background: #000;
    color: #fff;
  }

</style>
<div id="catestory">

  <a href="#" onclick="return false();" class="fakeLink">
    <div class="content">
      <h2>some title here</h2>
      <p>some content here</p>
    </div>
  </a>

  <a href="#" onclick="return false();" class="fakeLink">
    <div class="content">
      <h2>some title here</h2>
      <p>some content here</p>
    </div>
  </a>

  <a href="#" onclick="return false();" class="fakeLink">
    <div class="content">
      <h2>some title here</h2>
      <p>some content here</p>
    </div>
  </a>

</div>

On my network just setting http_proxy didn't work for me. The following points were relevant.

1 Setting http_proxy for your user wont be preserved when you execute sudo - to preserve it, do:

sudo -E yourcommand

I got my install working by first installing cntlm local proxy. The instructions here is succinct : http://www.leg.uct.ac.za/howtos/use-isa-proxies

Instead of student number, you'd put your domain username

2 To use the cntlm local proxy, exec:

pip install --proxy localhost:3128 pygments

Well, this is already in 2018 but I think it is better late than never (like a title in a TV program), lol. Down here is the jQuery code that I create during my thesis.

    });
    var activeTab = localStorage.getItem('activeTab');
    if(activeTab){
        $('#myTab a[href="' + activeTab + '"]').tab('show');
    }
});
</script>

and here is the code for bootstrap tabs:

Dont forget to call the bootstrap and other fundamental things 

here are quick codes for you:

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>

Now let's come to the explanation:

The jQuery code in the above example simply gets the element's href attribute value when a new tab has been shown using the jQuery .attr() method and save it locally in the user's browser through HTML5 localStorage object. Later, when the user refresh the page it retrieves this data and activate the related tab via .tab('show') method.

Looking up for some examples? here is one for you guys.. https://jsfiddle.net/Wineson123/brseabdr/

I wish my answer could help you all.. Cheerio! :)

Just a few minutes ago i was facing the same problem. I got the problem that is after just placing your jQuery start the other jQuery scripting. After all it will work fine.

Typical usage for conditional removal of error from Model State:

1. Make conditional first part of controller action
2. Perform logic to remove error from ModelState
3. Do the rest of the existing logic (typically Model State validation, then everything else)

Example:

public ActionResult MyAction(MyViewModel vm)
{
    // perform conditional test
    // if true, then remove from ModelState (e.g. ModelState.Remove("MyKey")

    // Do typical model state validation, inside following if:
    //     if (!ModelState.IsValid)

    // Do rest of logic (e.g. fetching, saving

In your example, keep everything as is and add the logic suggested to your Controller's Action. I'm assuming your ViewModel passed to the controller action has the Person and Senior Person objects with data populated in them from the UI.

In Bootstrap 3 (not tested in 4) you can override default colors with using a template when creating the tooltip. With this method you can specify tooltip colors runtime:

var bgColor = '#dd0000'; //red
var textColor = '#ffffff'; //white

$('#yourControlId').tooltip({
    placement: "top",
    template: '<div class="tooltip" role="tooltip"><div class="tooltip-arrow" style="border-top-color:' + bgColor + ';"></div><div class="tooltip-inner" style="background-color:' + bgColor + ';color:' + textColor + ';"></div></div>'
});

The template is based on original tooltip template. I only added the color styles. The placement must be top, because of arrow styling. (I haven't tried other placement types)

I've also faced a similar situation where I needed a script which can take care of javac and then java(ing) my java program. So, I came up with this BATCH script.

I think that the correct form to insert a value on a specify row is:

UPDATE table SET column = value WHERE columnid = 1

it works, and is similar if you write on Microsoft SQL Server

INSERT INTO table(column) VALUES (130) WHERE id = 1;

on mysql you have to Update the table.

You cant combine this to attributes.

But you can put both on one action method but you can encapsulate your logic into a other method and call this method from both actions.

The ActionName Attribute allows to have 2 ActionMethods with the same name.

[HttpGet]
public ActionResult MyMethod()
{
    return MyMethodHandler();
}

[HttpPost]
[ActionName("MyMethod")]
public ActionResult MyMethodPost()
{
    return MyMethodHandler();
}

private ActionResult MyMethodHandler()
{
    // handle the get or post request
    return View("MyMethod");
}

I added the start and exit which works. Without both it was not working

start C:/Anaconda3/Library/bin/pyrcc4.exe -py3 {path}/Resourses.qrc -{path}/Resourses_rc.py
exit

Try with this:

myListView.ItemsSource = new List< DictionaryEntry >();

Windows Character Encoding Issue

I was having the same issue. I was editing files in PDT Eclipse on Windows and WinSCPing them over. I just copied and pasted the contents into a nano window, saved, and now they worked. Definitely some Windows character encoding issue, and not a matter of Shebangs or interpreter flags.

If you have both Python2 and Python3 installed on your Mac, you can use

python --version

to check the version of Python2, and

python3 --version

to check the version of Python3.

However, if only Python3 is installed, then your system might use python instead of python3 for Python3. In this case, you can just use

python --version

to check the version of Python3.

require will throw a PHP Fatal Error if the file cannot be loaded. (Execution stops)

include produces a Warning if the file cannot be loaded. (Execution continues)

Here is a nice illustration of include and require difference:

Make second argument of Response false as shown below.

Response.Redirect(url,false);

Make that "three single comment-markers"

In C# it's ///

which as default spits out:

/// <summary>
/// 
/// </summary>
/// <returns></returns>

Here's some tips on editing VS templates.

-- IN arguments : you get them. You can modify them locally but caller won't see it
-- IN OUT arguments: initialized by caller, already have a value, you can modify them and the caller will see it
-- OUT arguments: they're reinitialized by the procedure, the caller will see the final value.
CREATE PROCEDURE f (p IN NUMBER, x IN OUT NUMBER, y OUT NUMBER)
IS
BEGIN
   x:=x * p;
   y:=4 * p;
END;
/

SET SERVEROUTPUT ON

declare
   foo number := 30;
   bar number := 0;
begin
   f(5,foo,bar);
   dbms_output.put_line(foo || ' ' || bar);
end;

When ever the array is declared, then only we have to add the key-value's in NSDictionary like

NSDictionary *normalDict = [[NSDictionary alloc]initWithObjectsAndKeys:@"Value1",@"Key1",@"Value2",@"Key2",@"Value3",@"Key3",nil];

we cannot add or remove the key values in this NSDictionary

Where as in NSMutableDictionary we can add the objects after intialization of array also by using this method

NSMutableDictionary *mutableDict = [[NSMutableDictionary alloc]init];'
[mutableDict setObject:@"Value1" forKey:@"Key1"];
[mutableDict setObject:@"Value2" forKey:@"Key2"];
[mutableDict setObject:@"Value3" forKey:@"Key3"];

for removing the key value we have to use the following code

[mutableDict removeObject:@"Value1" forKey:@"Key1"];

You can use the following

WebDriverWait wait = new WebDriverWait(driver, new TimeSpan(0,0,5));
wait.Until(ExpectedConditions.ElementToBeClickable((By.Id("login")));

I fixed the problem adding this binding redirect to my .config file:

<runtime>
    . . . 
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
        <dependentAssembly>
            <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed"
                culture="neutral" />
            <bindingRedirect oldVersion="4.5.0.0" newVersion="6.0.0.0" />
        </dependentAssembly>
    </assemblyBinding>
</runtime>

The error message complains about not finding version 4.5.0.0, the current version of Newtonsoft.Json is 6.0.0.0 so the redirect should go from 4.5 to 6.0, not viceversa

You appear to have a heredoc containing a single SQL*Plus command, though it doesn't look right as noted in the comments. You can either pass a value in the heredoc:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql BUILDING
exit;
EOF

or if BUILDING is $2 in your script:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql $2
exit;
EOF

If your file.sql had an exit at the end then it would be even simpler as you wouldn't need the heredoc:

sqlplus -S user/pass@localhost @/opt/D2RQ/file.sql $2

In your SQL you can then refer to the position parameters using substitution variables:

...
}',SEM_Models('&1'),NULL,
...

The &1 will be replaced with the first value passed to the SQL script, BUILDING; because that is a string it still needs to be enclosed in quotes. You might want to set verify off to stop if showing you the substitutions in the output.

You can pass multiple values, and refer to them sequentially just as you would positional parameters in a shell script - the first passed parameter is &1, the second is &2, etc. You can use substitution variables anywhere in the SQL script, so they can be used as column aliases with no problem - you just have to be careful adding an extra parameter that you either add it to the end of the list (which makes the numbering out of order in the script, potentially) or adjust everything to match:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql total_count BUILDING
exit;
EOF

or:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql total_count $2
exit;
EOF

If total_count is being passed to your shell script then just use its positional parameter, $4 or whatever. And your SQL would then be:

SELECT COUNT(*) as &1
FROM TABLE(SEM_MATCH(
'{
        ?s rdf:type :ProcessSpec .
        ?s ?p ?o
}',SEM_Models('&2'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));

If you pass a lot of values you may find it clearer to use the positional parameters to define named parameters, so any ordering issues are all dealt with at the start of the script, where they are easier to maintain:

define MY_ALIAS = &1
define MY_MODEL = &2

SELECT COUNT(*) as &MY_ALIAS
FROM TABLE(SEM_MATCH(
'{
        ?s rdf:type :ProcessSpec .
        ?s ?p ?o
}',SEM_Models('&MY_MODEL'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));

From your separate question, maybe you just wanted:

SELECT COUNT(*) as &1
FROM TABLE(SEM_MATCH(
'{
        ?s rdf:type :ProcessSpec .
        ?s ?p ?o
}',SEM_Models('&1'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));

... so the alias will be the same value you're querying on (the value in $2, or BUILDING in the original part of the answer). You can refer to a substitution variable as many times as you want.

That might not be easy to use if you're running it multiple times, as it will appear as a header above the count value in each bit of output. Maybe this would be more parsable later:

select '&1' as QUERIED_VALUE, COUNT(*) as TOTAL_COUNT

If you set pages 0 and set heading off, your repeated calls might appear in a neat list. You might also need to set tab off and possibly use rpad('&1', 20) or similar to make that column always the same width. Or get the results as CSV with:

select '&1' ||','|| COUNT(*)

Depends what you're using the results for...

from StringIO import StringIO
out = StringIO()
out = tree.export_graphviz(clf, out_file=out)
print out.getvalue()

You can see a digraph Tree. Then, clf.tree_.feature and clf.tree_.value are array of nodes splitting feature and array of nodes values respectively. You can refer to more details from this github source.

GregorianCalendar c = GregorianCalendar.from((LocalDate.parse("2016-06-22")).atStartOfDay(ZoneId.systemDefault()));

Not directly, no. But you could use a site, such as colorschemedesigner.com, that will give you your base color and then give you the hex and rgb codes for different ranges of your base color.

Once I find my color schemes for my site, I put the hex codes for the colors and name them inside a comment section at the top of my stylesheet.

I have another solution. If Alpha and Beta are your only extra class then why not make a static variable with the image of the class.

Like in Alpha class :

public class Alpha{
        public static Alpha alpha;
        public Alpha(){
                this.alpha = this;
}

Now you you can call the function in Beta class by just using these lines :

new Alpha();
Alpha.alpha.DoSomethingAlpha();

An executable file needs to have permissions for execute set before you can execute it.

In your machine where you are building the docker image (not inside the docker image itself) try running:

ls -la path/to/directory

The first column of the output for your executable (in this case docker-entrypoint.sh) should have the executable bits set something like:

-rwxrwxr-x

If not then try:

chmod +x docker-entrypoint.sh

and then build your docker image again.

Docker uses it's own file system but it copies everything over (including permissions bits) from the source directories.

If you are using Entity Framework like me, you should define Time out on Startup class as follows:

 services.AddDbContext<ApplicationDbContext>(options => options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection"), o => o.CommandTimeout(180)));

you have error in your code unexpected token.use:

  $('#purpose').on('change', function () {
   if (this.value == '1') {
    $("#business").show();
    } else {
    $("#business").hide();
   }

   });

Demo

Update: You can narrow down the code using .toggle()

 $('#purpose').on('change', function () {
   $("#business").toggle(this.value == '1');
 });

rem This is the command line version
cscript "C:\Users\guest\Desktop\123\MyScript.vbs"

OR

rem This is the windowed version
wscript "C:\Users\guest\Desktop\123\MyScript.vbs"

You can also add the option //e:vbscript to make sure the scripting engine will recognize your script as a vbscript.

Windows/DOS batch files doesn't require escaping \ like *nix.

You can still use "C:\Users\guest\Desktop\123\MyScript.vbs", but this requires the user has *.vbs associated to wscript.

The setstate is asynchronous in react, so to see the updated state in console use the callback as shown below (Callback function will execute after the setstate update)

The below method is "not recommended" but for understanding, if you mutate state directly you can see the updated state in the next line. I repeat this is "not recommended"

To do it without using a JavaScript library such as jQuery, you'd do it like this:

var span = document.getElementById("myspan"),
    text = document.createTextNode(''+intValue);
span.innerHTML = ''; // clear existing
span.appendChild(text);

If you do want to use jQuery, it's just this:

$("#myspan").text(''+intValue);

For Error: 'opts' is deprecated. Use theme() instead. (Defunct; last used in version 0.9.1)' I replaced opts(title = "Boxplot - Candidate's Tweet Scores") with labs(title = "Boxplot - Candidate's Tweet Scores"). It worked!

Apple push will reject a string for a variety of reasons. I tested a variety of scenarios for push delivery, and this was my working fix (in python):

#  Apple rejects push payloads > 256 bytes (truncate msg to < 120 bytes to be safe)
if len(push_str) > 120:
    push_str = push_str[0:120-3] + '...'

# Apple push rejects all quotes, remove them
import re
push_str = re.sub("[\"']", '', push_str)

# Apple push needs to newlines escaped
import MySQLdb
push_str = MySQLdb.escape_string(push_str)

# send it
import APNSWrapper
wrapper = APNSWrapper.APNSNotificationWrapper(certificate=...)
message = APNSWrapper.APNSNotification()
message.token(...)
message.badge(1)
message.alert(push_str)
message.sound("default")
wrapper.append(message)
wrapper.notify()

I've installed and use VB6 for legacy projects many times on Windows 7.

What I have done and never came across any issues, is to install VB6, ignore the errors and then proceed to install the latest service pack, currently SP6.

Download here: http://www.microsoft.com/en-us/download/details.aspx?id=5721

Bonus: Also once you install it and realize that scrolling doesn't work, use the below: http://www.joebott.com/vb6scrollwheel.htm

I've read that using document fragments is performant because it avoids page reflow upon each insertion of DOM element, it's also well supported by all browsers (even IE 6).

var fragment = document.createDocumentFragment();_x000D_
_x000D_
$.each(result, function() {_x000D_
  fragment.appendChild($("<option />").val(this.ImageFolderID).text(this.Name)[0]);_x000D_
});_x000D_
_x000D_
$("#options").append(fragment);

I first read about this in CodeSchool's JavaScript Best Practices course.

Here's a comparison of different approaches, thanks go to the author.

I think you put the function in the $(document).ready....... The functions are always provided out the $(document).ready.......

EDIT 2 (For IE10-11 Users): The solution above will not work with the changes Microsoft has made to the browser as of late, so here's an updated solution that will allow you to grayscale (or desaturate) your images.

<svg>_x000D_
  <defs>_x000D_
    <filter xmlns="http://www.w3.org/2000/svg" id="desaturate">_x000D_
      <feColorMatrix type="saturate" values="0" />_x000D_
    </filter>_x000D_
  </defs>_x000D_
  <image xlink:href="http://www.polyrootstattoo.com/images/Artists/Buda/40.jpg" width="600" height="600" filter="url(#desaturate)" />_x000D_
</svg>

If you use <tbody> or <tfoot> in your table, you'll have to use the following syntax or you'll get a incorrect value:

var rowCount = $('#myTable >tbody >tr').length;

I realize there are a ton of solutions here, but I found none of them hit every requirement I had:

• No custom coding required
• Code works on page load
• No custom classes required (checkboxes or their parent)
• I needed several checkbox lists to share the same name for submitting Github issues via their API, and was using the name label[] to assign labels across many form fields (two checkbox lists and a few selects and textboxes) - granted I could have achieved this without them sharing the same name, but I decided to try it, and it worked.

The only requirement for this one is jQuery. You can combine this with @ewall's great solution to add custom validation error messages.

Also check out include-what-you-use, which solves a similar problem.

If your server have a http service you can compress your directory and download the compressed file.

Compress:

tar -zcvf archive-name.tar.gz -C directory-name .

Download throught your browser:

http://the-server-ip/archive-name.tar.gz

If you don't have direct access to the server ip, do a ssh tunnel throught putty, and forward the 80 port in some local port, and you can download the file.

You have a view model to which your view is strongly typed => use strongly typed helpers:

<%= Html.DropDownListFor(
    x => x.SelectedAccountId, 
    new SelectList(Model.Accounts, "Value", "Text")
) %>

Also notice that I use a SelectList for the second argument.

And in your controller action you were returning the view model passed as argument and not the one you constructed inside the action which had the Accounts property correctly setup so this could be problematic. I've cleaned it a bit:

public ActionResult AccountTransaction()
{
    var accounts = Services.AccountServices.GetAccounts(false);
    var viewModel = new AccountTransactionView
    {
        Accounts = accounts.Select(a => new SelectListItem
        {
            Text = a.Description,
            Value = a.AccountId.ToString()
        })
    };
    return View(viewModel);
}

We're getting errors about duplicate configuration directives on the one of our apps. After investigation it looks like it's because of this issue.

In brief, our root website is ASP.NET 3.5 (which is 2.0 with specific libraries added), and we have a subapplication that is ASP.NET 4.0.

web.config inheritance causes the ASP.NET 4.0 sub-application to inherit the web.config file of the parent ASP.NET 3.5 application.

However, the ASP.NET 4.0 application's global (or "root") web.config, which resides at C:\Windows\Microsoft.NET\Framework\v4.0.30319\Config\web.config and C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Config\web.config (depending on your bitness), already contains these config sections.

The ASP.NET 4.0 app then tries to merge together the root ASP.NET 4.0 web.config, and the parent web.config (the one for an ASP.NET 3.5 app), and runs into duplicates in the node.

The only solution I've been able to find is to remove the config sections from the parent web.config, and then either

1. Determine that you didn't need them in your root application, or if you do
2. Upgrade the parent app to ASP.NET 4.0 (so it gains access to the root web.config's configSections)

If the performance is an issue, you can use this command in MS_DOS:

dir /OD >d:\dir.txt

This command generate a dir.txt file in **d:** root the have all files sorted by date. And then read the file from your code. Also, you add other filters by * and ?.

There is the possibility of making something really more cool!

# Powershell 
$xl = new-object -ComObject excell.application
$doc=$xl.workbooks.open("Filepath")
$doc.Sheets.item(1).rows |
% { ($_.value2 | Select-Object -first 3 | Select-Object -last 2) -join "," }

You can check that theHref is defined by checking against undefined.

if (undefined !== theHref && theHref.length) {
    // `theHref` is not undefined and has truthy property _length_
    // do stuff
} else {
    // do other stuff
}

If you want to also protect yourself against falsey values like null then check theHref is truthy, which is a little shorter

if (theHref && theHref.length) {
    // `theHref` is truthy and has truthy property _length_
}

This is an exeprt from Technet (so not sure why the marked answer says named pipes are faster??):

Named Pipes vs. TCP/IP Sockets

In a fast local area network (LAN) environment, Transmission Control Protocol/Internet Protocol (TCP/IP) Sockets and Named Pipes clients are comparable with regard to performance. However, the performance difference between the TCP/IP Sockets and Named Pipes clients becomes apparent with slower networks, such as across wide area networks (WANs) or dial-up networks. This is because of the different ways the interprocess communication (IPC) mechanisms communicate between peers.

For named pipes, network communications are typically more interactive. A peer does not send data until another peer asks for it using a read command. A network read typically involves a series of peek named pipes messages before it starts to read the data. These can be very costly in a slow network and cause excessive network traffic, which in turn affects other network clients.

It is also important to clarify if you are talking about local pipes or network pipes. If the server application is running locally on the computer that is running an instance of SQL Server, the local Named Pipes protocol is an option. Local named pipes runs in kernel mode and is very fast.

For TCP/IP Sockets, data transmissions are more streamlined and have less overhead. Data transmissions can also take advantage of TCP/IP Sockets performance enhancement mechanisms such as windowing, delayed acknowledgements, and so on. This can be very helpful in a slow network. Depending on the type of applications, such performance differences can be significant.

TCP/IP Sockets also support a backlog queue. This can provide a limited smoothing effect compared to named pipes that could lead to pipe-busy errors when you are trying to connect to SQL Server.

Generally, TCP/IP is preferred in a slow LAN, WAN, or dial-up network, whereas named pipes can be a better choice when network speed is not the issue, as it offers more functionality, ease of use, and configuration options.

I have set up a select with a custom arrow similar to Julio's answer, however it doesn't have a set width and uses an svg as a background image. (arrow_drop_down from material-ui icons)

select {
  -webkit-appearance: none;
  -moz-appearance: none;
  background: transparent;
  background-image: url("data:image/svg+xml;utf8,<svg fill='black' height='24' viewBox='0 0 24 24' width='24' xmlns='http://www.w3.org/2000/svg'><path d='M7 10l5 5 5-5z'/><path d='M0 0h24v24H0z' fill='none'/></svg>");
  background-repeat: no-repeat;
  background-position-x: 100%;
  background-position-y: 5px;
  border: 1px solid #dfdfdf;
  border-radius: 2px;
  margin-right: 2rem;
  padding: 1rem;
  padding-right: 2rem;
}

If you need it to also work in IE update the svg arrow to base64 and add the following:

select::-ms-expand { display: none; }

background-image: url(data:image/svg+xml;base64,PHN2ZyBmaWxsPSdibGFjaycgaGVpZ2h0PScyNCcgdmlld0JveD0nMCAwIDI0IDI0JyB3aWR0aD0nMjQnIHhtbG5zPSdodHRwOi8vd3d3LnczLm9yZy8yMDAwL3N2Zyc+PHBhdGggZD0nTTcgMTBsNSA1IDUtNXonLz48cGF0aCBkPSdNMCAwaDI0djI0SDB6JyBmaWxsPSdub25lJy8+PC9zdmc+);

To make it easier to size and space the arrow, use this svg:

url("data:image/svg+xml,<svg width='24' height='24' xmlns='http://www.w3.org/2000/svg'><path d='m0,6l12,12l12,-12l-24,0z'/><path fill='none' d='m0,0l24,0l0,24l-24,0l0,-24z'/></svg>");

It doesn't have any spacing on the arrow's sides.

This works:

SELECT STR_TO_DATE(dateColumn, '%c/%e/%Y %r') FROM tabbleName WHERE 1

Per the JQuery documentation, .get() only takes the url, data (content), dataType, and success callback as its parameters. What you're really looking to do here is modify the jqXHR object before it gets sent. With .ajax(), this is done with the beforeSend() method. But since .get() is a shortcut, it doesn't allow it.

It should be relatively easy to switch your .ajax() calls to .get() calls though. After all, .get() is just a subset of .ajax(), so you can probably use all the default values for .ajax() (except, of course, for beforeSend()).

Edit:

::Looks at Jivings' answer::

Oh yeah, forgot about the cache parameter! While beforeSend() is useful for adding other headers, the built-in cache parameter is far simpler here.

This has been answered above, but I wanted to suggest an alternative.

When in the Build Settings for you project or target, you can go to the Editor menu and select Show Setting Names from the menu. This will change all of the options in the Build Settings pane to the build variable names. The option in the menu changes to Show Setting Titles, select this to change back to the original view.

This can be handy when you know what build setting you want to use in a script, toggle the setting names in the menu and you can see the variable name.

Example for people who are from Python background and want to integrate their machine learning model in the Node.js application:

It uses the child_process core module:

const express = require('express')
const app = express()

app.get('/', (req, res) => {

    const { spawn } = require('child_process');
    const pyProg = spawn('python', ['./../pypy.py']);

    pyProg.stdout.on('data', function(data) {

        console.log(data.toString());
        res.write(data);
        res.end('end');
    });
})

app.listen(4000, () => console.log('Application listening on port 4000!'))

It doesn't require sys module in your Python script.

Below is a more modular way of performing the task using Promise:

const express = require('express')
const app = express()

let runPy = new Promise(function(success, nosuccess) {

    const { spawn } = require('child_process');
    const pyprog = spawn('python', ['./../pypy.py']);

    pyprog.stdout.on('data', function(data) {

        success(data);
    });

    pyprog.stderr.on('data', (data) => {

        nosuccess(data);
    });
});

app.get('/', (req, res) => {

    res.write('welcome\n');

    runPy.then(function(fromRunpy) {
        console.log(fromRunpy.toString());
        res.end(fromRunpy);
    });
})

app.listen(4000, () => console.log('Application listening on port 4000!'))

From what you printed, it seems var2 is an array containing one string. Or actually, it appears to hold the result of running .inspect on an array containing one string. It would be helpful to show how you are initializing them.

irb(main):005:0* v1 = "test"
=> "test"
irb(main):006:0> v2 = ["test"]
=> ["test"]
irb(main):007:0> v3 = v2.inspect
=> "[\"test\"]"
irb(main):008:0> puts v1,v2,v3
test
test
["test"]

This will change all worksheet objects' names (from the perspective of the VBA editor) to match that of their sheet names (from the perspective of Excel):

Sub ZZ_Reset_Sheet_CodeNames()
'Changes the internal object name (codename) of each sheet to it's conventional name (based on it's sheet name)

    Dim varItem As Variant

    For Each varItem In ThisWorkbook.VBProject.VBComponents
        'Type 100 is a worksheet
        If varItem.Type = 100 And varItem.Name <> "ThisWorkbook" Then
            varItem.Name = varItem.Properties("Name").Value
        End If
    Next
End Sub

It is important to note that the object name (codename) "(Name)" is being overridden by the property name "Name", and so it must be referenced as a sub-property.

AND will return you an answer only when both volunteer and uploaded are present in your column. Otherwise it will return null value...

I'm sorry, but in some case (for a very big set), Oracle could return this error:

Object or Collection value was too large. The size of the value
might have exceeded 30k in a SORT context, or the size might be
too big for available memory.

but I think this is a good point of start ;)
