In case of your python being an pyenv installed one, where pyenv is installed with homebrew on macOS, there might me a newer version available which fixes this:

$ brew update && brew upgrade pyenv

Then reinstalling the python version:

$ pyenv install 3.7.2
pyenv: /Users/luckydonald/.pyenv/versions/3.7.2 already exists
continue with installation? (y/N) 

Note, it is a bit dirty to overwrite the existing python install like that, but in my case it did work out.

Its actually formulated more like:

https://<bucket-name>.s3.amazonaws.com/<key>

See here

Sets have no order, but if you still want to get the first element you can use the following:

<c:forEach var="attachment" items="${attachments}" end="0">
     <c:out value="${attachment.id} />
</c:forEach>

After several attempts and going deep in Tomcat's source code I found out that the simple property useNaming="false" did the trick!! Now Tomcat resolves names java:/liferay instead of java:comp/env/liferay

Filtering IP Address in Wireshark:

(1)single IP filtering:

ip.addr==X.X.X.X

ip.src==X.X.X.X

ip.dst==X.X.X.X

(2)Multiple IP filtering based on logical conditions:

OR condition:

(ip.src==192.168.2.25)||(ip.dst==192.168.2.25)

AND condition:

(ip.src==192.168.2.25) && (ip.dst==74.125.236.16)

The Maven Wrapper is an excellent choice for projects that need a specific version of Maven (or for users that don't want to install Maven at all). Instead of installing many versions of it in the operating system, we can just use the project-specific wrapper script.

mvnw: it's an executable Unix shell script used in place of a fully installed Maven

mvnw.cmd: it's for Windows environment

Use Cases

The wrapper should work with different operating systems such as:

• Linux
• OSX
• Windows
• Solaris

After that, we can run our goals like this for the Unix system:

./mvnw clean install

And the following command for Batch:

./mvnw.cmd clean install

If we don't have the specified Maven in the wrapper properties, it'll be downloaded and installed in the folder $USER_HOME/.m2/wrapper/dists of the system.

Maven Wrapper plugin

Maven Wrapper plugin to make auto installation in a simple Spring Boot project.

First, we need to go in the main folder of the project and run this command:

mvn -N io.takari:maven:wrapper

We can also specify the version of Maven:

mvn -N io.takari:maven:wrapper -Dmaven=3.5.2

The option -N means –non-recursive so that the wrapper will only be applied to the main project of the current directory, not in any submodules.

Import jquery first before bootstrap:

<script src="js/jquery.min.js"></script>
<script src="js/bootstrap.js"></script>
<script src="js/bootstrap.bundle.js"></script>

Import namespace :

using System.Configuration;

Create ConfigurationElement Company :

public class Company : ConfigurationElement
{

        [ConfigurationProperty("name", IsRequired = true)]
        public string Name
        {
            get
            {
                return this["name"] as string;
            }
        }
            [ConfigurationProperty("code", IsRequired = true)]
        public string Code
        {
            get
            {
                return this["code"] as string;
            }
        }
}

ConfigurationElementCollection:

public class Companies
        : ConfigurationElementCollection
    {
        public Company this[int index]
        {
            get
            {
                return base.BaseGet(index) as Company ;
            }
            set
            {
                if (base.BaseGet(index) != null)
                {
                    base.BaseRemoveAt(index);
                }
                this.BaseAdd(index, value);
            }
        }

       public new Company this[string responseString]
       {
            get { return (Company) BaseGet(responseString); }
            set
            {
                if(BaseGet(responseString) != null)
                {
                    BaseRemoveAt(BaseIndexOf(BaseGet(responseString)));
                }
                BaseAdd(value);
            }
        }

        protected override System.Configuration.ConfigurationElement CreateNewElement()
        {
            return new Company();
        }

        protected override object GetElementKey(System.Configuration.ConfigurationElement element)
        {
            return ((Company)element).Name;
        }
    }

and ConfigurationSection:

public class RegisterCompaniesConfig
        : ConfigurationSection
    {

        public static RegisterCompaniesConfig GetConfig()
        {
            return (RegisterCompaniesConfig)System.Configuration.ConfigurationManager.GetSection("RegisterCompanies") ?? new RegisterCompaniesConfig();
        }

        [System.Configuration.ConfigurationProperty("Companies")]
            [ConfigurationCollection(typeof(Companies), AddItemName = "Company")]
        public Companies Companies
        {
            get
            {
                object o = this["Companies"];
                return o as Companies ;
            }
        }

    }

and you must also register your new configuration section in web.config (app.config):

<configuration>       
    <configSections>
          <section name="Companies" type="blablabla.RegisterCompaniesConfig" ..>

then you load your config with

var config = RegisterCompaniesConfig.GetConfig();
foreach(var item in config.Companies)
{
   do something ..
}

Count the Letters provided in string

Since Java 1.5, simple one line concatenation with "+" and StringBuilder.append() generate exactly the same bytecode.

So for the sake of code readability, use "+".

2 exceptions :

• multithreaded environment : StringBuffer
• concatenation in loops : StringBuilder/StringBuffer

Here is how you can do it on most desktop systems:

#ifdef _WIN32
    #include <windows.h>
#else
    #include <unistd.h>
#endif

void wait( int seconds )
{   // Pretty crossplatform, both ALL POSIX compliant systems AND Windows
    #ifdef _WIN32
        Sleep( 1000 * seconds );
    #else
        sleep( seconds );
    #endif
}

int
main( int argc, char **argv)
{
    int running = 3;
    while( running )
    {   // do something
        --running;
        wait( 3 );
    }
    return 0; // OK
}

Here is how you can do it on a microcomputer / processor w/o timer:

int wait_loop0 = 10000;
int wait_loop1 = 6000;

// for microprocessor without timer, if it has a timer refer to vendor documentation and use it instead.
void
wait( int seconds )
{   // this function needs to be finetuned for the specific microprocessor
    int i, j, k;
    for(i = 0; i < seconds; i++)
    {
        for(j = 0; j < wait_loop0; j++)
        {
            for(k = 0; k < wait_loop1; k++)
            {   // waste function, volatile makes sure it is not being optimized out by compiler
                int volatile t = 120 * j * i + k;
                t = t + 5;
            }
        }
    }
}

int
main( int argc, char **argv)
{
    int running = 3;
    while( running )
    {   // do something
        --running;
        wait( 3 );
    }
    return 0; // OK
}

The waitloop variables must be fine tuned, those did work pretty close for my computer, but the frequency scale thing makes it very imprecise for a modern desktop system; So don't use there unless you're bare to the metal and not doing such stuff.

The idle shortcut is an "Advertised Shortcut" which breaks certain features like the "find target" button. Google for more info.

You can view the link with a hex editor or download LNK Parser to see where it points to.

In my case it runs:

The '::' is for static members.

You can do something like this

import React from 'react';

class Header extends React.Component {

constructor() {
    super();
}

checkClick(e, notyId) {
    alert(notyId);
}

render() {
    return (
        <PopupOver func ={this.checkClick } />
    )
}
};

class PopupOver extends React.Component {

constructor(props) {
    super(props);
    this.props.func(this, 1234);
}

render() {
    return (
        <div className="displayinline col-md-12 ">
            Hello
        </div>
    );
}
}

export default Header;

Using statics

var MyComponent = React.createClass({
 statics: {
 customMethod: function(foo) {
  return foo === 'bar';
  }
 },
   render: function() {
 }
});

MyComponent.customMethod('bar');  // true

export NAME=value for settings and variables that have meaning to a subprocess.

NAME=value for temporary or loop variables private to the current shell process.

In more detail, export marks the variable name in the environment that copies to a subprocesses and their subprocesses upon creation. No name or value is ever copied back from the subprocess.

• A common error is to place a space around the equal sign:

  $ export FOO = "bar"  
  bash: export: `=': not a valid identifier
  

• Only the exported variable (B) is seen by the subprocess:

  $ A="Alice"; export B="Bob"; echo "echo A is \$A. B is \$B" | bash
  A is . B is Bob
  

• Changes in the subprocess do not change the main shell:

  $ export B="Bob"; echo 'B="Banana"' | bash; echo $B
  Bob
  

• Variables marked for export have values copied when the subprocess is created:

  $ export B="Bob"; echo '(sleep 30; echo "Subprocess 1 has B=$B")' | bash &
  [1] 3306
  $ B="Banana"; echo '(sleep 30; echo "Subprocess 2 has B=$B")' | bash 
  Subprocess 1 has B=Bob
  Subprocess 2 has B=Banana
  [1]+  Done         echo '(sleep 30; echo "Subprocess 1 has B=$B")' | bash
  

• Only exported variables become part of the environment (man environ):

   $ ALICE="Alice"; export BOB="Bob"; env | grep "ALICE\|BOB"
   BOB=Bob
  

So, now it should be as clear as is the summer's sun! Thanks to Brain Agnew, alexp, and William Prusell.

public static boolean BFS(ListNode n, int x){
        if(n==null){
           return false;
       }
Queue<ListNode<Integer>> q = new Queue<ListNode<Integer>>();
ListNode<Integer> tmp = new ListNode<Integer>(); 
q.enqueue(n);
tmp = q.dequeue();
if(tmp.val == x){
    return true;
}
while(tmp != null){
    for(ListNode<Integer> child: n.getChildren()){
        if(child.val == x){
            return true;
        }
        q.enqueue(child);
    }

    tmp = q.dequeue();
}
return false;
}

Depends, where you want to have the vertical line, but if you want a vertical border for example, you can have the parent view have a background a custom drawable. And you can then define the drawable like this:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
    <item>
        <shape
            android:shape="rectangle">
            <stroke android:width="1dp" android:color="#000000" />
            <solid android:color="#00ffffff" />

        </shape>
    </item>

    <item android:right="1dp">
        <shape android:shape="rectangle">
            <solid android:color="#00ffffff" />
        </shape>
    </item>

</layer-list>

This example will create a 1dp thin black line on the right side of the view, that will have this drawable as an background.

In Bootstrap 4 for Horizontal element you can use .row with .col-*-* classes to specify the width of your labels and controls. see this link.

And if you want to display a series of labels, form controls, and buttons on a single horizontal row you can use .form-inline for more info this link

For Windows Forms one way is to use the SoundPlayer

private void Button_Click(object sender, EventArgs e)
{
    using (var soundPlayer = new SoundPlayer(@"c:\Windows\Media\chimes.wav")) {
        soundPlayer.Play(); // can also use soundPlayer.PlaySync()
    }
}

MSDN page

This will also work with WPF, but you have other options like using MediaPlayer MSDN page

Use np.delete ! It does not actually delete anything inplace

Example:

import numpy as np
a = np.array([[1,4],[5,7],[3,1]])                                       

# a: array([[1, 4],
#           [5, 7],
#           [3, 1]])

ind = np.array([0,1])                                                   

# ind: array([0, 1])

# a[ind]: array([[1, 4],
#                [5, 7]])

all_except_index = np.delete(a, ind, axis=0)                                              
# all_except_index: array([[3, 1]])

# a: (still the same): array([[1, 4],
#                             [5, 7],
#                             [3, 1]])

Give this a try.

        FirmNames = String.Join(", \n", FirmNameList);

It depends on how you want to use it. Using a Join is one way. Another way of doing it is let the thread notify the caller of the thread by using an event. For instance when you have your graphical user interface (GUI) thread that calls a process which runs for a while and needs to update the GUI when it finishes, you can use the event to do this. This website gives you an idea about how to work with events:

http://msdn.microsoft.com/en-us/library/aa645739%28VS.71%29.aspx

Remember that it will result in cross-threading operations and in case you want to update the GUI from another thread, you will have to use the Invoke method of the control which you want to update.

Edit: CMake now has builtin support for this. See new answer.

You can also force the build of the dependent target in a secondary make process

See my answer on a related topic.

Pagination is generally a "user" operation and to prevent overload both on computers and the human brain you generally give a subset. However, rather than thinking that we don't get the whole list it may be better to ask does it matter?

If an accurate live scrolling view is needed, REST APIs which are request/response in nature are not well suited for this purpose. For this you should consider WebSockets or HTML5 Server-Sent Events to let your front end know when dealing with changes.

Now if there's a need to get a snapshot of the data, I would just provide an API call that provides all the data in one request with no pagination. Mind you, you would need something that would do streaming of the output without temporarily loading it in memory if you have a large data set.

For my case I implicitly designate some API calls to allow getting the whole information (primarily reference table data). You can also secure these APIs so it won't harm your system.

Extending Richard Cook's answer.

Here's the ant task to run any program (including, but not limited to Java programs):

<target name="run">
   <exec executable="name-of-executable">
      <arg value="${arg0}"/>
      <arg value="${arg1}"/>
   </exec>
</target>

Here's the task to run a Java program from a .jar file:

<target name="run-java">
   <java jar="path for jar">
      <arg value="${arg0}"/>
      <arg value="${arg1}"/>
   </java>
</target>

You can invoke either from the command line like this:

ant -Darg0=Hello -Darg1=World run

Make sure to use the -Darg syntax; if you ran this:

ant run arg0 arg1

then ant would try to run targets arg0 and arg1.

Did you try:

<Directory /path/to/your/wp-admin>
Order allow,deny
Allow from all
</Directory>

For me, the bug had two fixes.

1. Xml file which was named as SAMPLE.XML which was causing even the below solution to fail when deployed to aws ec2. The fix was to rename it to new_sample.xml and apply the solution given below.
2. Solution approach https://medium.com/@jonathan.henrique.smtp/reading-files-in-resource-path-from-jar-artifact-459ce00d2130

I was using Spring boot as jar and deployed to aws ec2 Java variant of the solution is as below :

package com.test;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.stream.Collectors;
import java.util.stream.Stream;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.core.io.Resource;


public class XmlReader {

    private static Logger LOGGER = LoggerFactory.getLogger(XmlReader.class);

  public static void main(String[] args) {


      String fileLocation = "classpath:cbs_response.xml";
      String reponseXML = null;
      try (ClassPathXmlApplicationContext appContext = new ClassPathXmlApplicationContext()){

        Resource resource = appContext.getResource(fileLocation);
        if (resource.isReadable()) {
          BufferedReader reader =
              new BufferedReader(new InputStreamReader(resource.getInputStream()));
          Stream<String> lines = reader.lines();
          reponseXML = lines.collect(Collectors.joining("\n"));

        }      
      } catch (IOException e) {
        LOGGER.error(e.getMessage(), e);
      }
  }
}

Use the Maven debug option, ie mvn -X :

Apache Maven 3.0.3 (r1075438; 2011-02-28 18:31:09+0100)
Maven home: /usr/java/apache-maven-3.0.3
Java version: 1.6.0_12, vendor: Sun Microsystems Inc.
Java home: /usr/java/jdk1.6.0_12/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "2.6.32-32-generic", arch: "i386", family: "unix"
[INFO] Error stacktraces are turned on.
[DEBUG] Reading global settings from /usr/java/apache-maven-3.0.3/conf/settings.xml
[DEBUG] Reading user settings from /home/myhome/.m2/settings.xml
...

In this output, you can see that the settings.xml is loaded from /home/myhome/.m2/settings.xml.

A simpler way to think about it, perhaps: when main returns, your process will not exit if there are non-daemon threads still running.

A bit of advice: Clean shutdown is easy to get wrong when threads and synchronization are involved - if you can avoid it, do so. Use daemon threads whenever possible.

The assignment operator has lower precedence than &&, so your condition is equivalent to:

if ((match == 0 && k) = m)

But the left-hand side of this is an rvalue, namely the boolean resulting from the evaluation of the sub­expression match == 0 && k, so you cannot assign to it.

By contrast, comparison has higher precedence, so match == 0 && k == m is equivalent to:

if ((match == 0) && (k == m))

dim mydate = from cv in mydata.t1s
  select cv.date1 asc

datetime mindata = mydate[0];

Update: 2017-01-10

Data URIs are now supported by all major browsers. IE supports embedding images since version 8 as well.

http://caniuse.com/#feat=datauri

Data URIs are now supported by the following web browsers:

• Gecko-based, such as Firefox, SeaMonkey, XeroBank, Camino, Fennec and K-Meleon
• Konqueror, via KDE's KIO slaves input/output system
• Opera (including devices such as the Nintendo DSi or Wii)
• WebKit-based, such as Safari (including on iOS), Android's browser, Epiphany and Midori (WebKit is a derivative of Konqueror's KHTML engine, but Mac OS X does not share the KIO architecture so the implementations are different), as well as Webkit/Chromium-based, such as Chrome
• Trident
  • Internet Explorer 8: Microsoft has limited its support to certain "non-navigable" content for security reasons, including concerns that JavaScript embedded in a data URI may not be interpretable by script filters such as those used by web-based email clients. Data URIs must be smaller than 32 KiB in Version 8[3].
  • Data URIs are supported only for the following elements and/or attributes[4]:
    • object (images only)
    • img
    • input type=image
    • link
  • CSS declarations that accept a URL, such as background-image, background, list-style-type, list-style and similar.
  • Internet Explorer 9: Internet Explorer 9 does not have 32KiB limitation and allowed in broader elements.
  • TheWorld Browser: An IE shell browser which has a built-in support for Data URI scheme

http://en.wikipedia.org/wiki/Data_URI_scheme#Web_browser_support

In addition to your CORS issue, the server you are trying to access has HTTP basic authentication enabled. You can include credentials in your cross-domain request by specifying the credentials in the URL you pass to the XHR:

url = 'http://username:[email protected]/testpage'

You can simply use one query to rule them all: ALTER TABLE products DROP FOREIGN KEY oldConstraintName, ADD FOREIGN KEY (product_id, category_id) REFERENCES externalTableName (foreign_key_name, another_one_makes_composite_key) ON DELETE CASCADE ON UPDATE CASCADE

Convert a string to a DateTime, you could try

    DateTime timeValue = Convert.ToDateTime("01:00 PM");
    Console.WriteLine(timeValue.ToString("HH:mm"));

Add ID attributes with same values as name attributes and then you can do this:

$('#first_name').change(function () {
  $('#firstname').val($(this).val());
});

Try removing the position from header and add overflow to container:

#container {
    position:relative;
    width:80%;
    height:auto;
    overflow:auto;
}
#header {
    width:80%;
    height:50px;
    padding:10px;
}

Note that if you split the variables into lines, you must use backslashes to wrap the newlines.

with A() as a, \
     B() as b, \
     C() as c:
    doSomething(a,b,c)

Parentheses don't work, since Python creates a tuple instead.

with (A(),
      B(),
      C()):
    doSomething(a,b,c)

Since tuples lack a __enter__ attribute, you get an error (undescriptive and does not identify class type):

AttributeError: __enter__

If you try to use as within parentheses, Python catches the mistake at parse time:

with (A() as a,
      B() as b,
      C() as c):
    doSomething(a,b,c)

SyntaxError: invalid syntax

When will this be fixed?

This issue is tracked in https://bugs.python.org/issue12782.

Recently, Python announced in PEP 617 that they'll be replacing the current parser with a new one. Because Python's current parser is LL(1), it cannot distinguish between "multiple context managers" with (A(), B()): and "tuple of values" with (A(), B())[0]:.

The new parser can properly parse "multiple context managers" surrounded by tuples. The new parser will be enabled in 3.9, but this syntax will still be rejected until the old parser is removed in Python 3.10.

I used the following on Mac OSX.

currDate=`date +%Y%m%d`
epochDate=$(date -j -f "%Y%m%d" "${currDate}" "+%s")

This can be resolved by adding the following line to the eclipse.ini file -XX:-UseCompressedOops

Here is an archived article from Jim Mischel at InformIt that handles sorting for both rectangular and jagged multi-dimensional arrays.

Well that is Because of

you are only able to encrypt data in blocks of 128 bits or 16 bytes. That's why you are getting that IllegalBlockSizeException exception. and the one way is to encrypt that data Directly into the String.

look this. Try and u will be able to resolve this

public static String decrypt(String encryptedData) throws Exception {

    Key key = generateKey();
    Cipher c = Cipher.getInstance(ALGO);
    c.init(Cipher.DECRYPT_MODE, key);
    String decordedValue = new BASE64Decoder().decodeBuffer(encryptedData).toString().trim();
    System.out.println("This is Data to be Decrypted" + decordedValue);
    return decordedValue;
}

hope that will help.

As you've figured out, Entity Framework can't actually run your C# code as part of its query. It has to be able to convert the query to an actual SQL statement. In order for that to work, you will have to restructure your query expression into an expression that Entity Framework can handle.

public System.Linq.Expressions.Expression<Func<Charity, bool>> IsSatisfied()
{
    string name = this.charityName;
    string referenceNumber = this.referenceNumber;
    return p => 
        (string.IsNullOrEmpty(name) || 
            p.registeredName.ToLower().Contains(name.ToLower()) ||
            p.alias.ToLower().Contains(name.ToLower()) ||
            p.charityId.ToLower().Contains(name.ToLower())) &&
        (string.IsNullOrEmpty(referenceNumber) ||
            p.charityReference.ToLower().Contains(referenceNumber.ToLower()));
}

Building on the above, if anyone needs to handle errors in the write/read streams, I used this version. Note the stream.read() in case of a write error, it's required so we can finish reading and trigger close on the read stream.

var download = function(uri, filename, callback){
  request.head(uri, function(err, res, body){
    if (err) callback(err, filename);
    else {
        var stream = request(uri);
        stream.pipe(
            fs.createWriteStream(filename)
                .on('error', function(err){
                    callback(error, filename);
                    stream.read();
                })
            )
        .on('close', function() {
            callback(null, filename);
        });
    }
  });
};

In classic mode IIS works h ISAPI extensions and ISAPI filters directly. And uses two pipe lines , one for native code and other for managed code. You can simply say that in Classic mode IIS 7.x works just as IIS 6 and you dont get extra benefits out of IIS 7.x features.

In integrated mode IIS and ASP.Net are tightly coupled rather then depending on just two DLLs on Asp.net as in case of classic mode.

Here is an easy way with String output (I created a method to do this):

public static String (String input){
    String output = "";
    try {
        /* From ISO-8859-1 to UTF-8 */
        output = new String(input.getBytes("ISO-8859-1"), "UTF-8");
        /* From UTF-8 to ISO-8859-1 */
        output = new String(input.getBytes("UTF-8"), "ISO-8859-1");
    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();
    }
    return output;
}
// Example
input = "Música";
output = "Música";

You can't use PHP in the WordPress back-end Page editor. Maybe with a plugin you can, but not out of the box.

The easiest solution for this is creating a shortcode. Then you can use something like this

function input_func( $atts ) {
    extract( shortcode_atts( array(
        'type' => 'text',
        'name' => '',
    ), $atts ) );

    return '<input name="' . $name . '" id="' . $name . '" value="' . (isset($_GET\['from'\]) && $_GET\['from'\] ? $_GET\['from'\] : '') . '" type="' . $type . '" />';
}
add_shortcode( 'input', 'input_func' );

See the Shortcode_API.

As the error message says in the last line: the module models in the file c:\projects\mysite..\mysite\polls\models.py contains no class model. This error occurs in the definition of the Poll class:

class Poll(models.model):

Either the class model is misspelled in the definition of the class Poll or it is misspelled in the module models. Another possibility is that it is completely missing from the module models. Maybe it is in another module or it is not yet implemented in models.

Another way, say in CentOS, is:

Run the code either in onload event, either just before you close body tag. You try to find an element wich is not there at the moment you do it.

I’m using this:

<!-- language: c# -->
private static string wmiProperty(string wmiClass, string wmiProperty){
  using (var searcher = new ManagementObjectSearcher($"SELECT * FROM {wmiClass}")) {
   try {
                    IEnumerable<ManagementObject> objects = searcher.Get().Cast<ManagementObject>();
                    return objects.Select(x => x.GetPropertyValue(wmiProperty)).FirstOrDefault().ToString().Trim();
                } catch (NullReferenceException) {
                    return null;
                }
            }
        }

Unirest library simplifies this a lot. If you want to use it, you have to install unirest npm package. Then your code could look like this:

unirest.get("http://graph.facebook.com/517267866/?fields=picture")
  .send()
  .end(response=> {
    if (response.ok) {
      console.log("Got a response: ", response.body.picture)
    } else {
      console.log("Got an error: ", response.error)
    }
  })

You need to subscribe to a SMS gateway. There are thousands of those (try searching with google) and they are usually not free. For example this one has support for PHP.

Since C++11 you could use std::put_time from iomanip header:

#include <iostream>
#include <iomanip>
#include <ctime>

int main()
{
    auto t = std::time(nullptr);
    auto tm = *std::localtime(&t);
    std::cout << std::put_time(&tm, "%d-%m-%Y %H-%M-%S") << std::endl;
}

std::put_time is a stream manipulator, therefore it could be used together with std::ostringstream in order to convert the date to a string:

#include <iostream>
#include <iomanip>
#include <ctime>
#include <sstream>

int main()
{
    auto t = std::time(nullptr);
    auto tm = *std::localtime(&t);

    std::ostringstream oss;
    oss << std::put_time(&tm, "%d-%m-%Y %H-%M-%S");
    auto str = oss.str();

    std::cout << str << std::endl;
}

I belive the answer is:

echo date('Y-m-d H:i:s');

You could do something like this

dict = [{
   "id": 1,
   "name": "Doom Hammer"
 },
 {
    "id": 2,
    "name": "Rings ov Saturn"
 }
]

for x in dict:
  if x["id"] == 2:
    print(x["name"])

Thats what i use to find the objects in a long array of objects.

Most likely you have some system-specific include directories missing in your settings which makes it impossible for indexer to correctly parse iostream, thus the errors. Selecting Index -> Search For Unresolved Includes in the context menu of the project will give you the list of unresolved includes which you can search in /usr/include and add containing directories to C++ Include Paths and Symbols in Project Properties.

On my system I had to add /usr/include/c++/4.6/x86_64-linux-gnu for bits/c++config.h to be resolved and a few more directories.

Don't forget to rebuild the index (Index -> Rebuild) after adding include directories.

I couldn't get the code posted by @Paolo Bergantino to work but when I changed it to $(document) and e.which instead of e.keyCode then I found it to work faultlessly.

$(document).keypress(function(e) {
    if(e.which == 13) {
        alert('You pressed enter!');
    }
});

Your clarification states: "I'm not going to use enums, I am not enumerating anything, just collecting some constants which are not related to each other in any way."

If the constants aren't related to each other at all, why do you want to collect them together? Put each constant in the class which it's most closely related to.

While astype is probably the "best" option there are several other ways to convert it to an integer array. I'm using this arr in the following examples:

>>> import numpy as np
>>> arr = np.array([1,2,3,4], dtype=float)
>>> arr
array([ 1.,  2.,  3.,  4.])

The int* functions from NumPy

>>> np.int64(arr)
array([1, 2, 3, 4])

>>> np.int_(arr)
array([1, 2, 3, 4])

The NumPy *array functions themselves:

>>> np.array(arr, dtype=int)
array([1, 2, 3, 4])

>>> np.asarray(arr, dtype=int)
array([1, 2, 3, 4])

>>> np.asanyarray(arr, dtype=int)
array([1, 2, 3, 4])

The astype method (that was already mentioned but for completeness sake):

>>> arr.astype(int)
array([1, 2, 3, 4])

Note that passing int as dtype to astype or array will default to a default integer type that depends on your platform. For example on Windows it will be int32, on 64bit Linux with 64bit Python it's int64. If you need a specific integer type and want to avoid the platform "ambiguity" you should use the corresponding NumPy types like np.int32 or np.int64.

I assume by "didn't work" you mean that it's giving you a timestamp instead of the formatted date, because you were doing it correctly:

$effectiveDate = strtotime("+3 months", strtotime($effectiveDate)); // returns timestamp
echo date('Y-m-d',$effectiveDate); // formatted version

You can use this code for bootstrap datepicker:

HTML Code:

<p>Date: <input type="text" id="datepicker" class="datepicker"></p>

Javascript:

$( ".datepicker" ).datepicker({
   format: 'yyyy-mm-dd'
});

Wildcards worked for me when the string I was searching for could be entered manually. However, I wanted to store this string in another cell and refer to it. I couldn't figure out how to do this with wildcards so I ended up doing the following:

A1 is the cell containing my search string. B and C are the columns within which I want to count the number of instances of A1, including within strings:

=COUNTIF(ARRAYFORMULA(ISNUMBER(SEARCH(A1, B:C))), TRUE)

I wanted to share the root cause for my issue. I was using High DPI in Windows and this caused JNLP to not launch. I had to turn off High DPI for this to work. Hope this helps.

Git pull is actually a combo tool: it runs git fetch (getting the changes) and git merge (merging them with your current copy)

Are you sure you are on the correct branch?

The following formula determines if the text "CHECK" appears in cell C10. If it does not, the result is blank. If it does, the result is the work "CHECK".

=IF(ISERROR(FIND("CHECK",C10,1)),"","CHECK")

Personally I don't like to use TempData, but I prefer to pass a strongly typed object as explained in Passing Information Between Controllers in ASP.Net-MVC.

You should always find a way to make it explicit and expected.

For windows users:

cd “C:\Program Files\Oracle\VirtualBox”
VBoxManage modifyhd “C:\Users\Chris\VirtualBox VMs\Windows 7\Windows 7.vdi” --resize 81920

I'm also about to ask the same question. But from what I've learned from codeacademy.com below code is enough to display the output or text?

print("hello world")  

The other methods work fine, but you can also use the good old django.shortcut.redirect.

The code below was taken from this answer.

In Django 2.x:

from django.shortcuts import redirect
from django.urls import path, include

urlpatterns = [
    # this example uses named URL 'hola-home' from app named hola
    # for more redirect's usage options: https://docs.djangoproject.com/en/2.1/topics/http/shortcuts/
    path('', lambda request: redirect('hola/', permanent=True)),
    path('hola/', include('hola.urls')),
]

There are a lot of half-truths here, so I thought I make some things clearer.

Actually you can't accurately tell if a variable exists (unless you want to wrap every second line into a try-catch block).

The reason is Javascript has this notorious value of undefined which strikingly doesn't mean that the variable is not defined, or that it doesn't exist undefined !== not defined

var a;
alert(typeof a); // undefined (declared without a value)
alert(typeof b); // undefined (not declared)

So both a variable that exists and another one that doesn't can report you the undefined type.

As for @Kevin's misconception, null == undefined. It is due to type coercion, and it's the main reason why Crockford keeps telling everyone who is unsure of this kind of thing to always use strict equality operator === to test for possibly falsy values. null !== undefined gives you what you might expect. Please also note, that foo != null can be an effective way to check if a variable is neither undefined nor null. Of course you can be explicit, because it may help readability.

If you restrict the question to check if an object exists, typeof o == "object" may be a good idea, except if you don't consider arrays objects, as this will also reported to be the type of object which may leave you a bit confused. Not to mention that typeof null will also give you object which is simply wrong.

The primal area where you really should be careful about typeof, undefined, null, unknown and other misteries are host objects. They can't be trusted. They are free to do almost any dirty thing they want. So be careful with them, check for functionality if you can, because it's the only secure way to use a feature that may not even exist.

you can add async option to false and return outside the ajax call.

function testAjax() {
    var result="";
    $.ajax({
      url:"getvalue.php",
      async: false,  
      success:function(data) {
         result = data; 
      }
   });
   return result;
}

I suggest setting it to Int32.MaxValue.

JavaScriptSerializer serializer = new JavaScriptSerializer();
serializer.MaxJsonLength = Int32.MaxValue;

So you need a natural sort ?

If so, than maybe this script by Brian Huisman based on David koelle's work would be what you need.

It seems like Brian Huisman's solution is now directly hosted on David Koelle's blog:

• Brian Huisman's javascript solutions
• David koelle's article on the subject

Presumably you're passing the arguments in on the command line as follows:

php /path/to/wwwpublic/path/to/script.php arg1 arg2

... and then accessing them in the script thusly:

<?php
// $argv[0] is '/path/to/wwwpublic/path/to/script.php'
$argument1 = $argv[1];
$argument2 = $argv[2];
?>

What you need to be doing when passing arguments through HTTP (accessing the script over the web) is using the query string and access them through the $_GET superglobal:

Go to http://yourdomain.com/path/to/script.php?argument1=arg1&argument2=arg2

... and access:

<?php
$argument1 = $_GET['argument1'];
$argument2 = $_GET['argument2'];
?>

If you want the script to run regardless of where you call it from (command line or from the browser) you'll want something like the following:

EDIT: as pointed out by Cthulhu in the comments, the most direct way to test which environment you're executing in is to use the PHP_SAPI constant. I've updated the code accordingly:

<?php
if (PHP_SAPI === 'cli') {
    $argument1 = $argv[1];
    $argument2 = $argv[2];
}
else {
    $argument1 = $_GET['argument1'];
    $argument2 = $_GET['argument2'];
}
?>

Since you've tagged your question 'php', I'll assume your running php on your server. Your best bet is if you control your own web server, then compile cURL into php. This will allow your web server to make requests to other web servers. This can be quite dangerous from a security point of view, so most basic web hosting providers won't have this option enabled.

Here's the php man page on using cURL. In the comments you can find an example which downloads and image file.

If you don't want to use libcurl, you could code something up using fsockopen. This is built into php (but may be disabled on your host), and can directly read and write to sockets. See Examples on the fsockopen man page.

Add the following aliases. I think these should be made available in PowerShell by default:

function not-exist { -not (Test-Path $args) }
Set-Alias !exist not-exist -Option "Constant, AllScope"
Set-Alias exist Test-Path -Option "Constant, AllScope"

With that, the conditional statements will change to:

if (exist $path) { ... }

and

if (not-exist $path) { ... }
if (!exist $path) { ... }

Arkaitz is correct that string is a managed type. What this means for you is that you never have to worry about how long the string is, nor do you have to worry about freeing or reallocating the memory of the string.

On the other hand, the char[] notation in the case above has restricted the character buffer to exactly 256 characters. If you tried to write more than 256 characters into that buffer, at best you will overwrite other memory that your program "owns". At worst, you will try to overwrite memory that you do not own, and your OS will kill your program on the spot.

Bottom line? Strings are a lot more programmer friendly, char[]s are a lot more efficient for the computer.

Intent i = new Intent("com.Android.SubActivity");
startActivity(i);

Wouldn't the generic T t = new T(); work?

To post a clarification answer here for those who get directed here by Google.

The document size includes everything in the document including the subdocuments, nested objects etc.

So a document of:

{
  "_id": {},
  "na": [1, 2, 3],
  "naa": [
    { "w": 1, "v": 2, "b": [1, 2, 3] },
    { "w": 5, "b": 2, "h": [{ "d": 5, "g": 7 }, {}] }
  ]
}

Has a maximum size of 16 MB.

Subdocuments and nested objects are all counted towards the size of the document.

More detailed information are available in the platform module.

To change the size of (almost) all text elements, in one place, and synchronously, rel() is quite efficient:
g+theme(text = element_text(size=rel(3.5))

You might want to tweak the number a bit, to get the optimum result. It sets both the horizontal and vertical axis labels and titles, and other text elements, on the same scale. One exception is faceted grids' titles which must be manually set to the same value, for example if both x and y facets are used in a graph:
theme(text = element_text(size=rel(3.5)), strip.text.x = element_text(size=rel(3.5)), strip.text.y = element_text(size=rel(3.5)))

Just clear the scope model value on click event and it should do the trick for you.

<input type="text" ng-model="searchAll" />
<a class="clear" ng-click="searchAll = null">
    <span class="glyphicon glyphicon-remove"></span>
</a>

Or if you keep your controller's $scope function and clear it from there. Make sure you've set your controller correctly.

$scope.clearSearch = function() {
    $scope.searchAll = null;
}

In my case, I stumbled upon one issue with using printf solution:

$ printf "%x" 008 bash: printf: 008: invalid octal number

The easiest way was to use solution with bc, suggested in post higher:

$ bc <<< "obase=16; 008" 8

With pure javascript you can do the following:

var buttons = document.getElementsByTagName("button");
var buttonsCount = buttons.length;
for (var i = 0; i < buttonsCount; i += 1) {
    buttons[i].onclick = function(e) {
        alert(this.id);
    };
}?

check it On JsFiddle

To get the id from the wildcard match:

$('[id^=pick_]').click(_x000D_
  function(event) {_x000D_
_x000D_
    // Do something with the id # here: _x000D_
    alert('Picked: '+ event.target.id.slice(5));_x000D_
_x000D_
  }_x000D_
);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div id="pick_1">moo1</div>_x000D_
<div id="pick_2">moo2</div>_x000D_
<div id="pick_3">moo3</div>

Migration to TestNG seems the best way, but I see no clear solution here for jUnit. Here is most readable solution / formatting I found for jUnit:

@FixMethodOrder(MethodSorters.NAME_ASCENDING)
public class SampleTest {
    @Test
    void stage1_prepareAndTest(){};

    @Test
    void stage2_checkSomething(){};

    @Test
    void stage2_checkSomethingElse(){};

    @Test
    void stage3_thisDependsOnStage2(){};

    @Test
    void callTimeDoesntMatter(){}
}

This ensures stage2 methods are called after stage1 ones and before stage3 ones.

You want

round(new MathContext(0));  // or perhaps another math context with rounding mode HALF_UP

If you want to have projects choice list when you open Git Bash:

• Edit ppath in the code header to your Git projects path, put this code into .bashrc file, and copy it into your $HOME directory (in Windows Vista / Windows 7 it is often C:\Users\$YOU)

.

#!/bin/bash
ppath="/d/-projects/-github"
cd $ppath
unset PROJECTS
PROJECTS+=(".")
i=0

echo
echo -e "projects:\n-------------"

for f in *
do
    if [ -d "$f" ]
    then
        PROJECTS+=("$f")
        echo -e $((++i)) "- \e[1m$f\e[0m"
    fi
done


if [ ${#PROJECTS[@]} -gt 1 ]
then
    echo -ne "\nchoose project: "
    read proj
    case "$proj" in
        [0-`expr ${#PROJECTS[@]} - 1`]) cd "${PROJECTS[proj]}" ;;
        *) echo " wrong choice" ;;
    esac
else
    echo "there is no projects"
fi
unset PROJECTS

• You may want set this file as executable inside Git Bash, chmod +x .bashrc (but it's probably redundant, since this file is stored on an NTFS filesystem)

"hard coding" means putting something into your source code. If you are not hard coding, then you do something like prompting the user for the data, or allow the user to put the data on the command line, or something like that.

So, to hard code the location of the file as being on the C: drive, you would just put the pathname of the file all together in your source code.

Here is an example.

int main()
{
    const char *filename = "C:\\myfile.txt";

    printf("Filename is: %s\n", filename);
}

The file name is "hard coded" as: C:\myfile.txt

The reason the backslash is doubled is because backslashes are special in C strings.

Don't use the slim build of jQuery, which doesn't have the ajax function in it. Use the full version instead from https://jquery.com/download/

Note: Make sure to not use the jquery link copied from Bootstrap website, because they use the slim version.

Just an addition to already good answers above.

Another trick I know is to store valuable codes as Java Library. Then set that Library to be your Android Project. Would be good as C .so file but Android Lib would do.

This way these valuable codes stored on Android Library won't be visible after decompiling.

This syntax isn't valid in any version of PostgreSQL:

ALTER SEQUENCE payments_id_seq LASTVALUE 22

This would work:

ALTER SEQUENCE payments_id_seq RESTART WITH 22;

And is equivalent to:

SELECT setval('payments_id_seq', 22, FALSE);

More in the current manual for ALTER SEQUENCE and sequence functions.

Note that setval() expects either (regclass, bigint) or (regclass, bigint, boolean). In the above example I am providing untyped literals. That works too. But if you feed typed variables to the function you may need explicit type casts to satisfy function type resolution. Like:

SELECT setval(my_text_variable::regclass, my_other_variable::bigint, FALSE);

For repeated operations you might be interested in:

ALTER SEQUENCE payments_id_seq START WITH 22; -- set default
ALTER SEQUENCE payments_id_seq RESTART;       -- without value

START [WITH] stores a default RESTART number, which is used for subsequent RESTART calls without value. You need Postgres 8.4 or later for the last part.

If you're getting this error because you're purposefully trying to build to Java 6, but you have Java 7 elsewhere in Eclipse, then it may be because you are referencing a Java 7 tools.jar in a Java 6 environment.

You'll need to install the JDK 6 (not JRE) and add the JRE 6 tools.jar as a User Entry in the Classpath of the build configuration, listed above the JRE 7 tools.jar.

Rename your js file to something else temporarily. This is the only thing that worked for me.

You could try using :placeholder-shown...

Re-posted as an answer: Found an alternative (Tested in Win8):

cmdkey /generic:"<server>" /user:"<user>" /pass:"<pass>"

Run that and if you run:

mstsc /v:<server>

You should not get an authentication prompt.

Use header to modify the HTTP header:

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

Note to call this function before any output has been sent to the client. Otherwise the header has been sent too and you obviously can’t change it any more. You can check that with headers_sent. See the manual page of header for more information.

The problem is WHEN the event is added and EXECUTED via triggering (the document onload property modification can be verified by examining the properties list).

When does this execute and modify onload relative to the onload event trigger:

document.addEventListener('load', ... );

before, during or after the load and/or render of the page's HTML?
This simple scURIple (cut & paste to URL) "works" w/o alerting as naively expected:

data:text/html;charset=utf-8,
    <html content editable><head>
          <script>
                document.addEventListener('load', function(){ alert(42) } );
          </script>
          </head><body>goodbye universe - hello muiltiverse</body>
    </html>

Does loading imply script contents have been executed?

A little out of this world expansion ...
Consider a slight modification:

data:text/html;charset=utf-8,
    <html content editable><head>
          <script>
              if(confirm("expand mind?"))document.addEventListener('load', function(){ alert(42) } );
          </script>
        </head><body>goodbye universe - hello muiltiverse</body>
    </html>

and whether the HTML has been loaded or not.

Rendering is certainly pending since goodbye universe - hello muiltiverse is not seen on screen but, does not the confirm( ... ) have to be already loaded to be executed? ... and so document.addEventListener('load', ... ) ... ?

In other words, can you execute code to check for self-loading when the code itself is not yet loaded?

Or, another way of looking at the situation, if the code is executable and executed then it has ALREADY been loaded as a done deal and to retroactively check when the transition occurred between not yet loaded and loaded is a priori fait accompli.

So which comes first: loading and executing the code or using the code's functionality though not loaded?

onload as a window property works because it is subordinate to the object and not self-referential as in the document case, ie. it's the window's contents, via document, that determine the loaded question err situation.

PS.: When do the following fail to alert(...)? (personally experienced gotcha's):

caveat: unless loading to the same window is really fast ... clobbering is the order of the day
so what is really needed below when using the same named window:

window.open(URIstr1,"w") .
   addEventListener('load', 
      function(){ alert(42); 
         window.open(URIstr2,"w") .
            addEventListener('load', 
               function(){ alert(43); 
                  window.open(URIstr3,"w") .
                     addEventListener('load', 
                        function(){ alert(44); 
                 /*  ...  */
                        } )
               } )
      } ) 

alternatively, proceed each successive window.open with:
alert("press Ok either after # alert shows pending load is done or inspired via divine intervention" );

data:text/html;charset=utf-8,
    <html content editable><head><!-- tagging fluff --><script>

        window.open(
            "data:text/plain, has no DOM or" ,"Window"
         ) . addEventListener('load', function(){ alert(42) } )

        window.open(
            "data:text/plain, has no DOM but" ,"Window"
         ) . addEventListener('load', function(){ alert(4) } )

        window.open(
            "data:text/html,<html><body>has DOM and", "Window"
         ) . addEventListener('load', function(){ alert(2) } )

        window.open(
            "data:text/html,<html><body>has DOM and", "noWindow"
         ) . addEventListener('load', function(){ alert(1) } )

        /* etc. including where body has onload=... in each appropriate open */

    </script><!-- terminating fluff --></head></html>

which emphasize onload differences as a document or window property.

Another caveat concerns preserving XSS, Cross Site Scripting, and SOP, Same Origin Policy rules which may allow loading an HTML URI but not modifying it's content to check for same. If a scURIple is run as a bookmarklet/scriplet from the same origin/site then there maybe success.

ie. From an arbitrary page, this link will do the load but not likely do alert('done'):

    <a href="javascript:window.open('view-source:http://google.ca') . 
                   addEventListener( 'load',  function(){ alert('done') }  )"> src. vu </a>

but if the link is bookmarked and then clicked when viewing a google.ca page, it does both.

test environment:

 window.navigator.userAgent = 
   Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.4) Gecko/2008102920 Firefox/3.0.4 (Splashtop-v1.2.17.0)

What you want to do is fetch the value from the input and assign it to a new Date instance.

let date = document.getElementById('dateInput');

let formattedDate = new Date(date.value);

console.log(formattedDate);

one has not been assigned so points to an unpredictable location. You should either place it on the stack:

Vector one;
one.a = 12;
one.b = 13;
one.c = -11

or dynamically allocate memory for it:

Vector* one = malloc(sizeof(*one))
one->a = 12;
one->b = 13;
one->c = -11
free(one);

Note the use of free in this case. In general, you'll need exactly one call to free for each call made to malloc.

Overview

@Mike's answer is correct but too imprecise. It is true that Python 3.3+ supports Implicit Namespace Packages that allows it to create a package without an __init__.py file. This is called a namespace package in contrast to a regular package which does have an __init__.py file (empty or not empty).

However, creating a namespace package should ONLY be done if there is a need for it. For most use cases and developers out there, this doesn't apply so you should stick with EMPTY __init__.py files regardless.

Namespace package use case

To demonstrate the difference between the two types of python packages, lets look at the following example:

google_pubsub/              <- Package 1
    google/                 <- Namespace package (there is no __init__.py)
        cloud/              <- Namespace package (there is no __init__.py)
            pubsub/         <- Regular package (with __init__.py)
                __init__.py <- Required to make the package a regular package
                foo.py

google_storage/             <- Package 2
    google/                 <- Namespace package (there is no __init__.py)
        cloud/              <- Namespace package (there is no __init__.py)
            storage/        <- Regular package (with __init__.py)
                __init__.py <- Required to make the package a regular package
                bar.py

google_pubsub and google_storage are separate packages but they share the same namespace google/cloud. In order to share the same namespace, it is required to make each directory of the common path a namespace package, i.e. google/ and cloud/. This should be the only use case for creating namespace packages, otherwise, there is no need for it.

It's crucial that there are no __init__py files in the google and google/cloud directories so that both directories can be interpreted as namespace packages. In Python 3.3+ any directory on the sys.path with a name that matches the package name being looked for will be recognized as contributing modules and subpackages to that package. As a result, when you import both from google_pubsub and google_storage, the Python interpreter will be able to find them.

This is different from regular packages which are self-contained meaning all parts live in the same directory hierarchy. When importing a package and the Python interpreter encounters a subdirectory on the sys.path with an __init__.py file, then it will create a single directory package containing only modules from that directory, rather than finding all appropriately named subdirectories outside that directory. This is perfectly fine for packages that don't want to share a namespace. I highly recommend taking a look at Traps for the Unwary in Python’s Import System to get a better understanding of how Python importing behaves with regular and namespace package and what __init__.py traps to watch out for.

Summary

• Only skip __init__.py files if you want to create namespace packages. Only create namespace packages if you have different libraries that reside in different locations and you want them each to contribute a subpackage to the parent package, i.e. the namespace package.
• Keep on adding empty __init__py to your directories because 99% of the time you just want to create regular packages. Also, Python tools out there such as mypy and pytest require empty __init__.py files to interpret the code structure accordingly. This can lead to weird errors if not done with care.

Resources

My answer only touches the surface of how regular packages and namespace packages work so take a look at the following resources for further information:

• PEP 420 -- Implicit Namespace Packages
• The import system - Regular packages
• The import system - Namespace packages
• Traps for the Unwary in Python’s Import System

Use the inspect module:

from inspect import getmembers, isfunction

from somemodule import foo
print(getmembers(foo, isfunction))

Also see the pydoc module, the help() function in the interactive interpreter and the pydoc command-line tool which generates the documentation you are after. You can just give them the class you wish to see the documentation of. They can also generate, for instance, HTML output and write it to disk.

drop table if exists foo;
create table foo
(
id int unsigned not null auto_increment primary key,
val smallint unsigned not null default 0
)
engine=innodb;

drop procedure if exists load_foo_test_data;

delimiter #
create procedure load_foo_test_data()
begin

declare v_max int unsigned default 1000;
declare v_counter int unsigned default 0;

  truncate table foo;
  start transaction;
  while v_counter < v_max do
    insert into foo (val) values ( floor(0 + (rand() * 65535)) );
    set v_counter=v_counter+1;
  end while;
  commit;
end #

delimiter ;

call load_foo_test_data();

select * from foo order by id;

If you're instantiating an android.support.v4.app.Fragment class, the you have to call getActivity().getSupportFragmentManager() to get rid of the cannot-resolve problem. However the official Android docs on Fragment by Google tends to over look this simple problem and they still document it without the getActivity() prefix.

Depends upon the version. The If operator in VB.NET 2008 is a ternary operator (as well as a null coalescence operator). This was just introduced, prior to 2008 this was not available. Here's some more info: Visual Basic If announcement

Example:

Dim foo as String = If(bar = buz, cat, dog)

[EDIT]

Prior to 2008 it was IIf, which worked almost identically to the If operator described Above.

Example:

Dim foo as String = IIf(bar = buz, cat, dog)

You can execute this in 2 simple statements:

row.names(samp) <- samp$names
samp[1] <- NULL

In comments debiasej wrote the mentioned below article explains more about design patterns (based on interfaces, classes):

http://loredanacirstea.github.io/es6-design-patterns/

Design patterns book in javascript may also be useful for you:

http://addyosmani.com/resources/essentialjsdesignpatterns/book/

Design pattern = classes + interface or multiple inheritance

An example of the factory pattern in ES6 JS (to run: node example.js):

"use strict";

// Types.js - Constructors used behind the scenes

// A constructor for defining new cars
class Car {
  constructor(options){
    console.log("Creating Car...\n");
    // some defaults
    this.doors = options.doors || 4;
    this.state = options.state || "brand new";
    this.color = options.color || "silver";
  }
}

// A constructor for defining new trucks
class Truck {
  constructor(options){
    console.log("Creating Truck...\n");
    this.state = options.state || "used";
    this.wheelSize = options.wheelSize || "large";
    this.color = options.color || "blue";
  }
}


// FactoryExample.js

// Define a skeleton vehicle factory
class VehicleFactory {}

// Define the prototypes and utilities for this factory

// Our default vehicleClass is Car
VehicleFactory.prototype.vehicleClass = Car;

// Our Factory method for creating new Vehicle instances
VehicleFactory.prototype.createVehicle = function ( options ) {

  switch(options.vehicleType){
    case "car":
      this.vehicleClass = Car;
      break;
    case "truck":
      this.vehicleClass = Truck;
      break;
    //defaults to VehicleFactory.prototype.vehicleClass (Car)
  }

  return new this.vehicleClass( options );

};

// Create an instance of our factory that makes cars
var carFactory = new VehicleFactory();
var car = carFactory.createVehicle( {
            vehicleType: "car",
            color: "yellow",
            doors: 6 } );

// Test to confirm our car was created using the vehicleClass/prototype Car

// Outputs: true
console.log( car instanceof Car );

// Outputs: Car object of color "yellow", doors: 6 in a "brand new" state
console.log( car );

var movingTruck = carFactory.createVehicle( {
                      vehicleType: "truck",
                      state: "like new",
                      color: "red",
                      wheelSize: "small" } );

// Test to confirm our truck was created with the vehicleClass/prototype Truck

// Outputs: true
console.log( movingTruck instanceof Truck );

// Outputs: Truck object of color "red", a "like new" state
// and a "small" wheelSize
console.log( movingTruck );

List<T> equality does not check them element-by-element. You can use LINQ's SequenceEqual method for that:

var a = ints1.SequenceEqual(ints2);

To ignore order, use SetEquals:

var a = new HashSet<int>(ints1).SetEquals(ints2);

This should work, because you are comparing sequences of IDs, which do not contain duplicates. If it does, and you need to take duplicates into account, the way to do it in linear time is to compose a hash-based dictionary of counts, add one for each element of the first sequence, subtract one for each element of the second sequence, and check if the resultant counts are all zeros:

var counts = ints1
    .GroupBy(v => v)
    .ToDictionary(g => g.Key, g => g.Count());
var ok = true;
foreach (var n in ints2) {
    int c;
    if (counts.TryGetValue(n, out c)) {
        counts[n] = c-1;
    } else {
        ok = false;
        break;
    }
}
var res = ok && counts.Values.All(c => c == 0);

Finally, if you are fine with an O(N*LogN) solution, you can sort the two sequences, and compare them for equality using SequenceEqual.

The following adds one line after SearchPattern.

sed -i '/SearchPattern/aNew Text' SomeFile.txt

It inserts New Text one line below each line that contains SearchPattern.

To add two lines, you can use a \ and enter a newline while typing New Text.

POSIX sed requires a \ and a newline after the a sed function. [1] Specifying the text to append without the newline is a GNU sed extension (as documented in the sed info page), so its usage is not as portable.

[1] https://unix.stackexchange.com/questions/52131/sed-on-osx-insert-at-a-certain-line/

The inclusion of your comparison class (or more specifically the AsEnumerable call you needed to use to get it to work) meant that the sorting logic went from being based on the database server to being on the database client (your application). This meant that your client now needs to retrieve and then process a larger number of records, which will always be less efficient that performing the lookup on the database where the approprate indexes can be used.

You should try to develop a where clause that satisfies your requirements instead, see Using an IEqualityComparer with a LINQ to Entities Except clause for more details.

Usual way to empty textbox using jquery is:

$('#txtInput').val('');

If above code is not working than please check that you are able to get the input element.

console.log($('#txtInput')); // should return element in the console.

If still facing the same problem, please post your code.

For Swift 4.2 and above

let supportEmail = "[email protected]"
if let emailURL = URL(string: "mailto:\(supportEmail)"), UIApplication.shared.canOpenURL(emailURL)
{
    UIApplication.shared.open(emailURL, options: [:], completionHandler: nil)
}

Give the user to choose many mail options(like iCloud, google, yahoo, Outlook.com - if no mail is pre-configured in his phone) to send email.

I think it's close. HTML 5 really needs to add the change event to the spec. The only problem is that the callback function evaluates if (before == $(this).html()) before the content is actually updated in $(this).html(). setTimeout don't work, and it's sad. Let me know what you think.

You can use string.match() and a regular expression for this too:

if(pathname.match(/^\/sub\/1/)) { // you need to escape the slashes

string.match() will return an array of matching substrings if found, otherwise null.

Install these packages:

• Microsoft.Extensions.Configuration
• Microsoft.Extensions.Configuration.Binder
• Microsoft.Extensions.Configuration.EnvironmentVariables
• Microsoft.Extensions.Configuration.FileExtensions
• Microsoft.Extensions.Configuration.Json

Code:

static void Main(string[] args)
    {
        var environmentName = Environment.GetEnvironmentVariable("ENVIRONMENT");
        Console.WriteLine("ENVIRONMENT: " + environmentName);

        var builder = new ConfigurationBuilder()
           .SetBasePath(Directory.GetCurrentDirectory())
           .AddJsonFile("appsettings.json", false)
           .AddJsonFile($"appsettings.{environmentName}.json", true)
           .AddEnvironmentVariables();

        IConfigurationRoot configuration = builder.Build();
        var mySettingsConfig = configuration.Get<MySettingsConfig>();

        Console.WriteLine("URL: " + mySettingsConfig.Url);
        Console.WriteLine("NAME: " + mySettingsConfig.Name);

        Console.ReadKey();
    }

MySettingsConfig Class:

public class MySettingsConfig
{
    public string Url { get; set; }
    public string Name { get; set; }
}

Your appsettings can be as simple as this:

Also, set the appsettings files to Content / Copy if newer:

A great option is to use jQuery/AJAX. Look at these examples and try them out on your server. In this example, in FILE1.php, note that it is passing a blank value. You can pass a value if you wish, which might look something like this (assuming javascript vars called username and password:

data: 'username='+username+'&password='+password,

In the FILE2.php example, you would retrieve those values like this:

$uname = $_POST['username'];
$pword = $_POST['password'];

Then do your MySQL lookup and return the values thus:

echo 'You are logged in';

This would deliver the message You are logged in to the success function in FILE1.php, and the message string would be stored in the variable called "data". Therefore, the alert(data); line in the success function would alert that message. Of course, you can echo anything that you like, even large amounts of HTML, such as entire table structures.

Here is another good example to review.

The approach is to create your form, and then use jQuery to detect the button press and submit the data to a secondary PHP file via AJAX. The above examples show how to do that.

The secondary PHP file receives the variables (if any are sent) and returns a response (whatever you choose to send). That response then appears in the Success: section of your AJAX call as "data" (in these examples).

The jQuery/AJAX code is javascript, so you have two options: you can place it within <script type="text/javascript"></script> tags within your main PHP document, or you can <?php include "my_javascript_stuff.js"; ?> at the bottom of your PHP document. If you are using jQuery, don't forget to include the jQuery library as in the examples given.

In your case, it sounds like you can pretty much mirror the first example I suggested, sending no data and receiving the response in the AJAX success function. Whatever you need to do with that data, though, you must do inside the success function. Seems a bit weird at first, but it works.

Think of it as a kind of turnstile like you might find at a football ground. There are parallel steams of people wanting to get in but at the turnstile they are 'synchronised'. Only one person at a time can get through. All those wanting to get through will do, but they may have to wait until they can go through.

Maybe there's a more simple answer, try to add any background color you like to the code, like background-color: #fff;

#alpha {
 background-color: #fff;
 opacity: 0.8;
 filter: alpha(opacity=80);
}

I want to use R rather than pre-processing the data as it makes it easier when the data are revised. Following Shane's suggestion of using gsub, I think this is about as neat as I can do:

x <- read.csv("file.csv",header=TRUE,colClasses="character")
col2cvt <- 15:41
x[,col2cvt] <- lapply(x[,col2cvt],function(x){as.numeric(gsub(",", "", x))})

needs name of string and its length will zero all characters other methods might stop at the first zero they encounter

    void strClear(char p[],u8 len){u8 i=0; 
        if(len){while(i<len){p[i]=0;i++;}}
    }

You can do it with a pivot query, like this:

select * from (
   select LOAN_NUMBER, DOCUMENT_TYPE, DOCUMENT_ID
   from my_table t
)
pivot 
(
   MIN(DOCUMENT_ID)
   for DOCUMENT_TYPE in ('Voters ID','Pan card','Drivers licence')
)

Here is a demo on sqlfiddle.com.

Try to use the empty() function:

<xsl:if test="empty(node/ABC/node()) and empty(node/DEF/node())">
    <xsl:text>This should work</xsl:text>
</xsl:if>

This identifies ABC and DEF as empty in the sense that they do not have any child nodes (no elements, no text nodes, no processing instructions, no comments).

But, as pointed out by @Ian, your elements might not be empty really or that might not be your actual problem - you did not show what your input XML looks like.

Another cause of error could be your relative position in the tree. This way of testing conditions only works if the surrounding template matches the parent element of node or if you iterate over the parent element of node.

The extern keyword informs the compiler that the function or variable has external linkage - in other words, that it is visible from files other than the one in which it is defined. In this sense it has the opposite meaning to the static keyword. It is a bit weird to put extern at the time of the definition, since no other files would have visibility of the definition (or it would result in multiple definitions). Normally you put extern in a declaration at some point with external visibility (such as a header file) and put the definition elsewhere.

One of the Roslyn engineers who specializes in understanding optimization of stack usage took a look at this and reports to me that there seems to be a problem in the interaction between the way the C# compiler generates local variable stores and the way the JIT compiler does register scheduling in the corresponding x86 code. The result is suboptimal code generation on the loads and stores of the locals.

For some reason unclear to all of us, the problematic code generation path is avoided when the JITter knows that the block is in a try-protected region.

This is pretty weird. We'll follow up with the JITter team and see whether we can get a bug entered so that they can fix this.

Also, we are working on improvements for Roslyn to the C# and VB compilers' algorithms for determining when locals can be made "ephemeral" -- that is, just pushed and popped on the stack, rather than allocated a specific location on the stack for the duration of the activation. We believe that the JITter will be able to do a better job of register allocation and whatnot if we give it better hints about when locals can be made "dead" earlier.

Thanks for bringing this to our attention, and apologies for the odd behaviour.

The ordinal() function returns the relative position of the identifier in the enum. You can use this to obtain automatic indexing with an offset, as with a C-style enum.

Example:

public class TestEnum {
    enum ids {
        OPEN,
        CLOSE,
        OTHER;

        public final int value = 100 + ordinal();
    };

    public static void main(String arg[]) {
        System.out.println("OPEN:  " + ids.OPEN.value);
        System.out.println("CLOSE: " + ids.CLOSE.value);
        System.out.println("OTHER: " + ids.OTHER.value);
    }
};

Gives the output:

OPEN:  100

Edit: just realized this is very similar to ggrandes' answer, but I will leave it here because it is very clean and about as close as you can get to a C style enum.

I have used POI.

If you use that, keep on eye those cell formatters: create one and use it several times instead of creating each time for cell, it isa huge memory consumption difference or large data.

This worked for me:

String result = input.replaceAll("string1|string2|string3","replacementString");

Example:

String input = "applemangobananaarefruits";
String result = input.replaceAll("mango|are|ts","-");
System.out.println(result);

Output: apple-banana-frui-

This is one of the very good and step by step process to set up PostgreSQL in ubuntu server. I have tried it with Ubuntu 16.04 and its working.

You close the second Scanner which closes the underlying InputStream, therefore the first Scanner can no longer read from the same InputStream and a NoSuchElementException results.

The solution: For console apps, use a single Scanner to read from System.in.

Aside: As stated already, be aware that Scanner#nextInt does not consume newline characters. Ensure that these are consumed before attempting to call nextLine again by using Scanner#newLine().

See: Do not create multiple buffered wrappers on a single InputStream

Here is what I found out to achieve a similar problem with my data set.

First, do what James mentioned above, i.e.

test[ , order(names(test))]

Second, use the everything() function in dplyr to move specific columns of interest (e.g., "D", "G", "K") at the beginning of the data frame, putting the alphabetically ordered columns after those ones.

select(test, D, G, K, everything())

­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­

@echo off

:: read a file line by line
for /F  %%i in ('type data.csv') do (
    echo %%i
    :: and we extract four tokens, ; is the delimiter.
    for /f "tokens=1,2,3,4 delims=;" %%a in ("%%i") do (
        set first=%%a&set second=%%b&set third=%%c&set fourth=%%d
        echo %first% and %second% and %third% and %fourth% 
    )
)

What you are referring to is metadata, data about data. I had this same issue for the project I am currently working on and had to spend some time trying to figure it out. It's too much information to post here, but below are two links you may find useful. They do reference the Symfony framework, but are based on the Doctrine ORM.

There is a visual studio plugin to support the java language: http://visualstudiogallery.msdn.microsoft.com/bc561769-36ff-4a40-9504-e266e8706f93

Per this announcement, Anaconda upgraded to Python 3.6 starting with version 4.3, so... you probably want the 4.2.0 package from the installer archive.

Ternary Operator

Commonly we have conditional statements in Javascript.

Example:

if (true) {
    console.log(1)
} 
else {
    console.log(0)
}
# Answer
# 1

but it contain two or more lines and cannot assign to a variable. Javascript have a solution for this Problem Ternary Operator. Ternary Operator can write in one line and assign to a variable.

Example:

var operator = true ? 1 : 0
console.log(operator)
# Answer
# 1

This Ternary operator is Similar in C programming language.

The easiest (as in least amount of new code required) way to do this is to run the test as a parametrized test (annotate with an @RunWith(Parameterized.class) and add a method to provide 10 empty parameters). That way the framework will run the test 10 times.

This test would need to be the only test in the class, or better put all test methods should need to be run 10 times in the class.

Here is an example:

@RunWith(Parameterized.class)
public class RunTenTimes {

    @Parameterized.Parameters
    public static Object[][] data() {
        return new Object[10][0];
    }

    public RunTenTimes() {
    }

    @Test
    public void runsTenTimes() {
        System.out.println("run");
    }
}

With the above, it is possible to even do it with a parameter-less constructor, but I'm not sure if the framework authors intended that, or if that will break in the future.

If you are implementing your own runner, then you could have the runner run the test 10 times. If you are using a third party runner, then with 4.7, you can use the new @Rule annotation and implement the MethodRule interface so that it takes the statement and executes it 10 times in a for loop. The current disadvantage of this approach is that @Before and @After get run only once. This will likely change in the next version of JUnit (the @Before will run after the @Rule), but regardless you will be acting on the same instance of the object (something that isn't true of the Parameterized runner). This assumes that whatever runner you are running the class with correctly recognizes the @Rule annotations. That is only the case if it is delegating to the JUnit runners.

If you are running with a custom runner that does not recognize the @Rule annotation, then you are really stuck with having to write your own runner that delegates appropriately to that Runner and runs it 10 times.

Note that there are other ways to potentially solve this (such as the Theories runner) but they all require a runner. Unfortunately JUnit does not currently support layers of runners. That is a runner that chains other runners.

I made it work with keyup.

$("#id input").trigger('keyup');

The printf command will print the complete strings:

(gdb) printf "%s\n", string

left:auto;

This will default the left back to the browser default.

So if you have your Markup/CSS as:

<div class="myClass"></div>

.myClass
{
  position:absolute;
  left:0;
}

When setting RTL, you could change to:

<div class="myClass rtl"></div>

.myClass
{
  position:absolute;
  left:0;
}
.myClass.rtl
{
  left:auto;
  right:0;
}

HTML alone does not support this. You need to use some JS.

And also consider nowadays people use popup blocker in browsers.

<a href="javascript:window.open('document.aspx','mypopuptitle','width=600,height=400')">open popup</a>

Just Android studio run 'Run as administrator' it will work

Or verify your package name on google-services.json file

If you want fix the column you should set width. For example:

<td style="width:100px;">some data</td>

Using only "native" Windows utilities, try the following, where "516" is the process ID that you want the image name for:

for /f "delims=," %a in ( 'tasklist /fi "PID eq 516" /nh /fo:csv' ) do ( echo %~a )
for /f %a in ( 'tasklist /fi "PID eq 516" ^| findstr "516"' ) do ( echo %a )

Or you could use wmic (the Windows Management Instrumentation Command-line tool) and get the full path to the executable:

wmic process where processId=516 get name
wmic process where processId=516 get ExecutablePath

Or you could download Microsoft PsTools, or specifically download just the pslist utility, and use PsList:

for /f %a in ( 'pslist 516 ^| findstr "516"' ) do ( echo %a )

You can tell Git what to do with your index (set of files that will become the next commit) and working directory when performing git reset by using one of the parameters:

--soft: Only commits will be reseted, while Index and the working directory are not altered.

--mixed: This will reset the index to match the HEAD, while working directory will not be touched. All the changes will stay in the working directory and appear as modified.

--hard: It resets everything (commits, index, working directory) to match the HEAD.

In your case, I would use git reset --soft to keep your modified changes in Index and working directory. Be sure to check this out for a more detailed explanation.

Sorry, no reputation to add this as a comment. So it goes as an complementary answer.

Depending on how often you will call clock_gettime(), you should keep in mind that only some of the "clocks" are provided by Linux in the VDSO (i.e. do not require a syscall with all the overhead of one -- which only got worse when Linux added the defenses to protect against Spectre-like attacks).

While clock_gettime(CLOCK_MONOTONIC,...), clock_gettime(CLOCK_REALTIME,...), and gettimeofday() are always going to be extremely fast (accelerated by the VDSO), this is not true for, e.g. CLOCK_MONOTONIC_RAW or any of the other POSIX clocks.

This can change with kernel version, and architecture.

Although most programs don't need to pay attention to this, there can be latency spikes in clocks accelerated by the VDSO: if you hit them right when the kernel is updating the shared memory area with the clock counters, it has to wait for the kernel to finish.

Here's the "proof" (GitHub, to keep bots away from kernel.org): https://github.com/torvalds/linux/commit/2aae950b21e4bc789d1fc6668faf67e8748300b7

I would do it this way:

try {
  txtProt = (EditText) findViewById(R.id.Protein); // Same
  p = txtProt.getText().toString(); // Same
  protein = Double.parseDouble(p); // Make use of autoboxing.  It's also easier to read.
} catch (NumberFormatException e) {
  // p did not contain a valid double
}

EDIT: "the program force closes immediately without leaving any info in the logcat"

I don't know bout not leaving information in the logcat output, but a force-close generally means there's an uncaught exception - like a NumberFormatException.

No Javascript required.

IE6 Internet Explorer 6

Percent only works for the width of an element, but height:100%; does not work without the correct code.

CSS

html, body { height:100%; } 

Then using a percentage works properly, and dynamically updates on window resize.

<img src="image.jpg" style="height:80%;">

You do not need a width attribute, the width scales proportionately as the browser window size is changed.

And this little gem, is in case the image is scaled up, it will not look (overly) blocky (it interpolates).

img { -ms-interpolation-mode: bicubic; }

Both Activity and Service actually extend Context so you can simply use this as your Context within your Service.

NotificationManager notificationManager =
    (NotificationManager) getSystemService(Service.NOTIFICATION_SERVICE);
Notification notification = new Notification(/* your notification */);
PendingIntent pendingIntent = /* your intent */;
notification.setLatestEventInfo(this, /* your content */, pendingIntent);
notificationManager.notify(/* id */, notification);

List<Integer> figureTypes = new ArrayList<Integer>(

                                 2
                            ));

List<Integer> figureTypes2 = new ArrayList<Integer>(
                           Arrays.asList(

                                 2));

assertTrue(figureTypes .equals(figureTypes2 ));

This is code I used in Windows. It works.

    name,value = item.split('=', 1)
    name=name.replace(' ', '').replace('\r', '').replace('\n', '')
    value = value.replace(' ', '').replace('\r', '').replace('\n', '')
    cookie_dict={
            'name':name,

I found it useful to get a location of the library file with:

gem which *gemname*

you can do this as below in typescript

 const _params = {} as any;

 _params.name ='nazeh abel'

since typescript does not behave like javascript so we have to make the type as any otherwise it won't allow you to assign property dynamically to an object

If mysql is already installed

Stop mysql completely.

1. mysql.server stop <-- may need editing based on your version
2. ps -ef | grep mysql <-- lists processes with mysql in their name
3. kill [PID] <-- kill the processes by PID

Remove files. Instructions above are good. I'll add:

1. sudo find /. -name "*mysql*"
2. Using your judgement, rm -rf these files. Note that many programs have drivers for mysql which you do not want to remove. For example, don't delete stuff in a PHP install's directory. Do remove stuff in its own mysql directory.

Install

Hopefully you have homebrew. If not, download it.

I like to run brew as root, but I don't think you have to. Edit 2018: you can't run brew as root anymore

1. sudo brew update
2. sudo brew install cmake <-- dependency for mysql, useful
3. sudo brew install openssl <-- dependency for mysql, useful
4. sudo brew info mysql <-- skim through this... it gives you some idea of what's coming next
5. sudo brew install mysql --with-embedded; say done <-- Installs mysql with the embedded server. Tells you when it finishes (my install took 10 minutes)

Afterwards

1. sudo chown -R mysql /usr/local/var/mysql/ <-- mysql wouldn't work for me until I ran this command
2. sudo mysql.server start <-- once again, the exact syntax may vary
3. Create users in mysql (http://dev.mysql.com/doc/refman/5.7/en/create-user.html). Remember to add a password for the root user.

What's happening here is the following: You create a new file on your trunk, then you merge it into your branch. In the merge commit this file will be created in your branch also.

When you merge your branch back into the trunk, SVN tries to do the same again: It sees that a file was created in your branch, and tries to create it in your trunk in the merge commit, but it already exists! This creates a tree conflict.

The way to avoid this, is to do a special merge, a reintegration. You can achieve this with the --reintegrate switch.

You can read about this in the documentation: http://svnbook.red-bean.com/en/1.7/svn.branchmerge.basicmerging.html#svn.branchemerge.basicmerging.reintegrate

When merging your branch back to the trunk, however, the underlying mathematics are quite different. Your feature branch is now a mishmash of both duplicated trunk changes and private branch changes, so there's no simple contiguous range of revisions to copy over. By specifying the --reintegrate option, you're asking Subversion to carefully replicate only those changes unique to your branch. (And in fact, it does this by comparing the latest trunk tree with the latest branch tree: the resulting difference is exactly your branch changes!)

After reintegrating a branch it is highly advisable to remove it, otherwise you will keep getting treeconflicts whenever you merge in the other direction: from the trunk to your branch. (For exactly the same reason as described before.)

There is a way around this too, but I never tried it. You can read it in this post: Subversion branch reintegration in v1.6

Color.parseColor("#rrggbb")

instead of #rrggbb you should be using hex values 0 to F for rr, gg and bb:

e.g. Color.parseColor("#000000") or Color.parseColor("#FFFFFF")

Source

From documentation:

public static int parseColor (String colorString):

Parse the color string, and return the corresponding color-int. If the string cannot be parsed, throws an IllegalArgumentException exception. Supported formats are: #RRGGBB #AARRGGBB 'red', 'blue', 'green', 'black', 'white', 'gray', 'cyan', 'magenta', 'yellow', 'lightgray', 'darkgray', 'grey', 'lightgrey', 'darkgrey', 'aqua', 'fuschia', 'lime', 'maroon', 'navy', 'olive', 'purple', 'silver', 'teal'

So I believe that if you are using #rrggbb you are getting IllegalArgumentException in your logcat

Source

Alternative:

Color mColor = new Color();
mColor.red(redvalue);
mColor.green(greenvalue);
mColor.blue(bluevalue);
li.setBackgroundColor(mColor);

We can do it with another approach too, Like first of all get the hash value from js and call the ajax using that parameter and can do whatever we want

This is a method I wrote. It takes an integer milliseconds value and returns a human-readable String:

public String convertMS(int ms) {
    int seconds = (int) ((ms / 1000) % 60);
    int minutes = (int) (((ms / 1000) / 60) % 60);
    int hours = (int) ((((ms / 1000) / 60) / 60) % 24);

    String sec, min, hrs;
    if(seconds<10)  sec="0"+seconds;
    else            sec= ""+seconds;
    if(minutes<10)  min="0"+minutes;
    else            min= ""+minutes;
    if(hours<10)    hrs="0"+hours;
    else            hrs= ""+hours;

    if(hours == 0)  return min+":"+sec;
    else    return hrs+":"+min+":"+sec;

}

For python 3

import datetime
now = datetime.datetime.now()
print(now.year, now.month, now.day, now.hour, now.minute, now.second)

I was finding the same error complaining about mixing google play services version when switching from 8.3 to 8.4. Bizarrely I saw reference to the app-measurement lib which I wasn't using.

I thought maybe one of my app's dependencies was referencing the older version so I ran ./gradlew app:dependencies to find the offending library (non were).

But at the top of task output I found a error message saying that the google plugin could not be found and defaulting to google play services 8.3. I used the sample project @TheYann linked to compare. My setup was identical except I applied the apply plugin: 'com.google.gms.google-services' at the top my app's build.gradle file. I moved to bottom of the file and that fixed the gradle compile error.

another way from MySQL Workbench:

Try this:

body {
  background-image:url(img/background.jpg);
  background-repeat: no-repeat;
  min-height: 679px;
  background-size: cover;
}

This is working nicely.

UPDATE state SET name = CONCAT(UCASE(LEFT(name, 1)), LCASE(SUBSTRING(name, 2)));

The &nKByte creates a temporary value, which cannot be bound to a reference to non-const.

You could change void test(float *&x) to void test(float * const &x) or you could just drop the pointer altogether and use void test(float &x); /*...*/ test(nKByte);.

Well the question is already answered, however what I am writing here is just my observation so other fellows in the community can save some of their time. I tried running a spring-mvc project using the embedded tom-cat in Intellij communit edition.

First try I did was using the Gradle tom-cat plugin, however the problem that I faced there is the tomcat server just starts once, after that from the second start the build complains saying that a container is already running. There are so many open thread on the web about this, for some it works and for most of the people (almost 90% of the web threads that I broke my head with, faced the same problem of container not getting started the second time. The resolution is not there.

After wasting a lot lot of my time, I finally decided to switch to maven tom-cat plugin and do the same spring-mvc setup with maven that I did with gradle and VOILA! it worked in the first short.

So long story short, if you are setting up spring-mvc project in intellij community edition, please consider maven tomcat plugin.

Hope this helps somebody's hours of exploration across various web forums.

  // if find is empty string return all indexes.
  if (!find) {
    // or shorter arrow function:

If you want to execute a SQL command and your variables are array members, then you should not use single quotes inside [] of array (like this: ['']); for example if you use this string as a SQL command, you get server error 500:

$con = mysqli_connect('ServerName', 'dbUsername', 'dbPassword');
mysqli_select_db($con, 'dbName')

//'ID' is auto increment field.
$sql = "INSERT INTO sampleTable (ID, TraceNo) VALUES ('','$sampleArray['TraceNo']')";
mysqli_query($con, $sql)

The correct string is:

//'ID' is auto increment field.
$sql = "INSERT INTO sampleTable (ID, TraceNo) VALUES ('','$sampleArray[TraceNo]')";

It seems like Jetbrains made some renaming and moved settings around so the accepted answer is no longer 100% valid anymore.

If you want to just format the output no need to create a new table or a function. In this scenario the area code was on a separate fields. I use field1, field2 just to illustrate you can select other fields in the same query:

area  phone
213   8962102

Select statement:

Select field1, field2,areacode,phone,SUBSTR(tablename.areacode,1,3) + '-' + SUBSTR(tablename.phone,1,3) + '-' + SUBSTR(tablename.areacode,4,4) as Formatted Phone from tablename

Sample OUTPUT:

columns: FIELD1, FIELD2, AREA, PHONE, FORMATTED PHONE
data:    Field1, Field2, 213,  8962102,  213-896-2102

You can fake it like this:

-- with column headings 
select column1, column2 from some_table;

-- without column headings
select column1 as '', column2 as '' from some_table;

If you want to use that on localhost, then use WAMP.

I can't get that constructor to work either. This however seems to work:

# $temp = Get-ResourceFiles
$resourceFiles = New-Object System.Collections.ArrayList($null)
$resourceFiles.AddRange($temp)

You can also pass an integer in the constructor to set an initial capacity.

What do you mean when you say you want to enumerate the files? Why can't you just filter the wanted values into a fresh array?

Edit:

It seems that you can use the array constructor like this:

$resourceFiles = New-Object System.Collections.ArrayList(,$someArray)

Note the comma. I believe what is happening is that when you call a .NET method, you always pass parameters as an array. PowerShell unpacks that array and passes it to the method as separate parameters. In this case, we don't want PowerShell to unpack the array; we want to pass the array as a single unit. Now, the comma operator creates arrays. So PowerShell unpacks the array, then we create the array again with the comma operator. I think that is what is going on.

I had to specify individual commands first and then use the * to bring all in command.

addItem(Object) takes an object. The default JComboBox renderer calls toString() on that object and that's what it shows as the label.

So, don't pass in a String to addItem(). Pass in an object whose toString() method returns the label you want. The object can contain any number of other data fields also.

Try passing this into your combobox and see how it renders. getSelectedItem() will return the object, which you can cast back to Widget to get the value from.

public final class Widget {
    private final int value;
    private final String label;

    public Widget(int value, String label) {
        this.value = value;
        this.label = label;
    }

    public int getValue() {
        return this.value;
    }

    public String toString() {
        return this.label;
    }
}

Gmail require SMTP communication with their server to be encrypted. Although you're opening up a connection to Gmail's server on port 465, unfortunately you won't be able to communicate with it in plaintext as Gmail require you to use STARTTLS/SSL encryption for the connection.

No you can't.

You can change the size to make it larger... similar to Dreas idea, but it is the size you need to change.

<select id="countries" size="6">
  <option value="1">Country 1</option>
  <option value="2">Country 2</option>
  <option value="3">Country 3</option>
  <option value="4">Country 4</option>
  <option value="5">Country 5</option>
  <option value="6">Country 6</option>

If the FileInfo class has more than one ancestor class then you should definitely call all of their __init__() functions. You should also do the same for the __del__() function, which is a destructor.

#include <sstream>

template <class T>
inline std::string to_string (const T& t)
{
   std::stringstream ss;
   ss << t;
   return ss.str();
}

Then your usage would look something like this

   std::string szName = "John";
   int numAge = 23;
   szName += to_string<int>(numAge);
   cout << szName << endl;

I have had similar issue on a Xamarin Project. It is maybe rare case but in case anyone else is having the issue. my project structure was like below

• xamarin.Android project had a reference from xamarin.android.library project.
• I created a plugin using some code from android.library project.
• Now here is the problem. if you add project reference or nuget installation on xamarin.android library project. You will get this error. Developers assume that code was inside Android.Library project and i must reference the new plugin on this project. NO!
• you must add a reference on Main Android project. because plugin->library->main project output isnt produced.

The Standard says (at 14/3. For the non-standard folks, the names following a class definition body (or the type in a declaration in general) are "declarators")

In a template-declaration, explicit specialization, or explicit instantiation the init-declarator-list in the dec-laration shall contain at most one declarator. When such a declaration is used to declare a class template, no declarator is permitted.

Do it like Andrey shows.

In material ui, state of checkbox can be fetched as

this.refs.complete.state.switched

Google page have a link that you can download the source code and the full tree.

Go to the Source tab, then click on Browse

then you see the link for Download it as:

In my case 415 Unsupported Media Types was received since I used new FormData() and sent it with axios.post(...) but did not set headers: {content-type: 'multipart/form-data'}. I also had to do the same on the server side:

[Consumes("multipart/form-data")]
public async Task<IActionResult> FileUpload([FromForm] IFormFile formFile) { ... }

You may want to have a look at https://isocpp.org/wiki/faq/pointers-to-members#fnptr-vs-memfnptr-types, especially [33.1] Is the type of "pointer-to-member-function" different from "pointer-to-function"?

I do it in Kotlin like this:

open class BaseAppCompatActivity : AppCompatActivity(), NavigationView.OnNavigationItemSelectedListener {

protected lateinit var drawerLayout: DrawerLayout
protected lateinit var navigationView: NavigationView
@Inject
lateinit var loginService: LoginService

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    Log.d("BaseAppCompatActivity", "onCreate()")
    App.getComponent().inject(this)
    drawerLayout = findViewById(R.id.drawer_layout) as DrawerLayout

    val toolbar = findViewById(R.id.toolbar) as Toolbar
    setSupportActionBar(toolbar)

    navigationView = findViewById(R.id.nav_view) as NavigationView
    navigationView.setNavigationItemSelectedListener(this)

    val toggle = ActionBarDrawerToggle(this, drawerLayout, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close)

    drawerLayout.addDrawerListener(toggle)
    toggle.syncState()
    toggle.isDrawerIndicatorEnabled = true

    val navigationViewHeaderView = navigationView.getHeaderView(0)
    navigationViewHeaderView.login_txt.text = SharedKey.username
}
private inline fun <reified T: Activity> launch():Boolean{
    if(this is T) return closeDrawer()
    val intent = Intent(applicationContext, T::class.java)
    startActivity(intent)
    finish()
    return true
}

private fun closeDrawer(): Boolean {
    drawerLayout.closeDrawer(GravityCompat.START)
    return true
}
override fun onNavigationItemSelected(item: MenuItem): Boolean {
    val id = item.itemId

    when (id) {
        R.id.action_tasks -> {
            return launch<TasksActivity>()
        }
        R.id.action_contacts -> {
            return launch<ContactActivity>()
        }
        R.id.action_logout -> {
            createExitDialog(loginService, this)
        }
    }
    return false
}
}

Activities for drawer must inherit this BaseAppCompatActivity, call super.onCreate after content is set (actually, can be moved to some init method) and have corresponding elements for ids in their layout

This has already been answered perfectly, but since I just came to this page and did not understand immediately I am just going to add a simple but complete example.

def some_func(a_char, a_float, a_something):
    print a_char

params = ['a', 3.4, None]
some_func(*params)

>> a

I was having a problem with ASP.NET MVC 5 where CheckBoxFor would not check my checkboxes on server-side validation failure even though my model clearly had the value set to true. My Razor markup/code looked like:

@Html.CheckBoxFor(model => model.MyBoolValue, new { @class = "mySpecialClass" } )

To get this to work, I had to change this to:

@{
    var checkboxAttributes = Model.MyBoolValue ?
        (object) new { @class = "mySpecialClass", @checked = "checked" } :
        (object) new { @class = "mySpecialClass" };
}
@Html.CheckBox("MyBoolValue", checkboxAttributes)

I would do as follows;

var num = 10,_x000D_
  dynar = [...Array(num)].map((_,i) => ++i+"");_x000D_
console.log(dynar);

Private Sub main()

'replace "J2" with the cell you want to insert the drop down list
With Range("J2").Validation
    .Delete
    'replace "=A1:A6" with the range the data is in.
    .Add Type:=xlValidateList, AlertStyle:=xlValidAlertStop, _
    Operator:=xlBetween, Formula1:="=Sheet1!A1:A6"
    .IgnoreBlank = True
    .InCellDropdown = True
    .InputTitle = ""
    .ErrorTitle = ""
    .InputMessage = ""
    .ErrorMessage = ""
    .ShowInput = True
    .ShowError = True
End With
End Sub

You can also use interface builder if you don't want to make the adjustments in code. Here I left align the text and also indent it some:

Don't forget you can also align an image in the button too.:

Another option would be using flexbox.

While it's not supported by IE8 and IE9, you could consider:

• Not minding about those old IE versions
• Providing a fallback
• Using a polyfill

Despite some additional browser-specific style prefixing would be necessary for full cross-browser support, you can see the basic usage either on this fiddle and on the following snippet:

html {_x000D_
  height: 100%;_x000D_
}_x000D_
html body {_x000D_

If these are the parameters of url-string then you need to add them through '?' and '&' chars, for example http://example.com/index.aspx?username=Api_user&password=Api_password.

If these are the parameters of POST request, then you need to create POST data and write it to request stream. Here is sample method:

private static string doRequestWithBytesPostData(string requestUri, string method, byte[] postData,
                                        CookieContainer cookieContainer,
                                        string userAgent, string acceptHeaderString,
                                        string referer,
                                        string contentType, out string responseUri)
        {
            var result = "";
            if (!string.IsNullOrEmpty(requestUri))
            {
                var request = WebRequest.Create(requestUri) as HttpWebRequest;
                if (request != null)
                {
                    request.KeepAlive = true;
                    var cachePolicy = new RequestCachePolicy(RequestCacheLevel.BypassCache);
                    request.CachePolicy = cachePolicy;
                    request.Expect = null;
                    if (!string.IsNullOrEmpty(method))
                        request.Method = method;
                    if (!string.IsNullOrEmpty(acceptHeaderString))
                        request.Accept = acceptHeaderString;
                    if (!string.IsNullOrEmpty(referer))
                        request.Referer = referer;
                    if (!string.IsNullOrEmpty(contentType))

                        request.UserAgent = userAgent;
                    if (cookieContainer != null)
                        request.CookieContainer = cookieContainer;

                    request.Timeout = Constants.RequestTimeOut;

                    if (request.Method == "POST")
                    {
                        if (postData != null)
                        {
                            request.ContentLength = postData.Length;
                            using (var dataStream = request.GetRequestStream())
                            {
                                dataStream.Write(postData, 0, postData.Length);
                            }
                        }
                    }

                    using (var httpWebResponse = request.GetResponse() as HttpWebResponse)
                    {
                        if (httpWebResponse != null)
                        {
                            responseUri = httpWebResponse.ResponseUri.AbsoluteUri;
                            cookieContainer.Add(httpWebResponse.Cookies);

Here's a simple little function that will rbind two datasets together after auto-detecting what columns are missing from each and adding them with all NAs.

For whatever reason this returns MUCH faster on larger datasets than using the merge function.

fastmerge <- function(d1, d2) {
  d1.names <- names(d1)
  d2.names <- names(d2)

  # columns in d1 but not in d2
  d2.add <- setdiff(d1.names, d2.names)

  # columns in d2 but not in d1
  d1.add <- setdiff(d2.names, d1.names)

  # add blank columns to d2
  if(length(d2.add) > 0) {
    for(i in 1:length(d2.add)) {
      d2[d2.add[i]] <- NA
    }
  }

  # add blank columns to d1
  if(length(d1.add) > 0) {
    for(i in 1:length(d1.add)) {
      d1[d1.add[i]] <- NA
    }
  }

  return(rbind(d1, d2))
