add this code to your project

  public static class Extension {
        public static string TextAfter(this string value ,string search) {
            return  value.Substring(value.IndexOf(search) + search.Length);
        }
  }

then use

"code : string text ".TextAfter(":")

All variables are cached so the loop and keyup event doesn't have to create a jQuery object everytime it runs.

var $input = $('input:text'),
    $register = $('#register');    
$register.attr('disabled', true);

$input.keyup(function() {
    var trigger = false;
    $input.each(function() {
        if (!$(this).val()) {
            trigger = true;
        }
    });
    trigger ? $register.attr('disabled', true) : $register.removeAttr('disabled');
});

This is asking the wrong question. The right question to ask is, why am I spending time sorting socks? How much does it cost on yearly basis, when you value your free time for X monetary units of your choice?

And more often than not, this is not just any free time, it's morning free time, which you could be spending in bed, or sipping your coffee, or leaving a bit early and not being caught in the traffic.

It's often good to take a step back, and think a way around the problem.

And there is a way!

Find a sock you like. Take all relevant features into account: colour in different lighting conditions, overall quality and durability, comfort in different climatic conditions, and odour absorption. Also important is, they should not lose elasticity in storage, so natural fabrics are good, and they should be available in a plastic wrapping.

It's better if there's no difference between left and right foot socks, but it's not critical. If socks are left-right symmetrical, finding a pair is O(1) operation, and sorting the socks is approximate O(M) operation, where M is the number of places in your house, which you have littered with socks, ideally some small constant number.

If you chose a fancy pair with different left and right sock, doing a full bucket sort to left and right foot buckets take O(N+M), where N is the number of socks and M is same as above. Somebody else can give the formula for average iterations of finding the first pair, but worst case for finding a pair with blind search is N/2+1, which becomes astronomically unlikely case for reasonable N. This can be sped up by using advanced image recognition algorithms and heuristics, when scanning the pile of unsorted socks with Mk1 Eyeball.

So, an algorithm for achieving O(1) sock pairing efficiency (assuming symmetrical sock) is:

1. You need to estimate how many pairs of socks you will need for the rest of your life, or perhaps until you retire and move to warmer climates with no need to wear socks ever again. If you are young, you could also estimate how long it takes before we'll all have sock-sorting robots in our homes, and the whole problem becomes irrelevant.

2. You need to find out how you can order your selected sock in bulk, and how much it costs, and do they deliver.

3. Order the socks!

4. Get rid of your old socks.

An alternative step 3 would involve comparing costs of buying the same amount of perhaps cheaper socks a few pairs at a time over the years and adding the cost of sorting socks, but take my word for it: buying in bulk is cheaper! Also, socks in storage increase in value at the rate of stock price inflation, which is more than you would get on many investments. Then again there is also storage cost, but socks really do not take much space on the top shelf of a closet.

Problem solved. So, just get new socks, throw/donate your old ones away, and live happily ever after knowing you are saving money and time every day for the rest of your life.

If you need form inside tr and inputs in every td, you can add form in td tag, and add attribute 'form' that contains id of form tag to outside inputs. Something like this:

<tr>
  <td>
    <form id='f1'>
      <input type="text">
    </form>
  </td>
  <td>
    <input form='f1' type="text">
  </td>
</tr>

sys.dm_exec_procedure_stats contains the information about the execution functions, constraints and Procedures etc. But the life time of the row has a limit, The moment the execution plan is removed from the cache the entry will disappear.

Use [yourDatabaseName]
GO
SELECT  
        SCHEMA_NAME(sysobject.schema_id),
        OBJECT_NAME(stats.object_id), 
        stats.last_execution_time
    FROM   
        sys.dm_exec_procedure_stats stats
        INNER JOIN sys.objects sysobject ON sysobject.object_id = stats.object_id 
    WHERE  
        sysobject.type = 'P'
    ORDER BY
           stats.last_execution_time DESC  

This will give you the list of the procedures recently executed.

If you want to check if a perticular stored procedure executed recently

SELECT  
    SCHEMA_NAME(sysobject.schema_id),
    OBJECT_NAME(stats.object_id), 
    stats.last_execution_time
FROM   
    sys.dm_exec_procedure_stats stats
    INNER JOIN sys.objects sysobject ON sysobject.object_id = stats.object_id 
WHERE  
    sysobject.type = 'P'
    and (sysobject.object_id = object_id('schemaname.procedurename') 
    OR sysobject.name = 'procedurename')
ORDER BY
       stats.last_execution_time DESC  

Or if you use the six library

from six.moves import reduce

This is the obvious slow solution (O(n^2)) if neither sorting nor hashing is feasible, but equality comparison (==) is available:

def most_common(items):
  if not items:
    raise ValueError
  fitems = [] 
  best_idx = 0
  for item in items:   
    item_missing = True
    i = 0
    for fitem in fitems:  
      if fitem[0] == item:
        fitem[1] += 1
        d = fitem[1] - fitems[best_idx][1]
        if d > 0 or (d == 0 and fitems[best_idx][2] > fitem[2]):
          best_idx = i
        item_missing = False
        break
      i += 1
    if item_missing:
      fitems.append([item, 1, i])
  return items[best_idx]

But making your items hashable or sortable (as recommended by other answers) would almost always make finding the most common element faster if the length of your list (n) is large. O(n) on average with hashing, and O(n*log(n)) at worst for sorting.

You might be better off editing a file inside of cygwin shell. Normally it has default user directory when you start it up. You can edit a file from the shell doing something like "vi somefile.c" or "emacs somefile.c". That's assuming vi or emacs are installed in cygwin.

If you want to file on your desktop, you'll have to go to a path similar (on XP) to "/cygwindrive/c/Documents\ and\ Settings/Frank/Desktop" (If memory serves correctly). Just cd to that path, and run your command on the file.

An easy way to perform an if in lambda is by using list comprehension.

You can't raise an exception in lambda, but this is a way in Python 3.x to do something close to your example:

f = lambda x: print(x) if x==2 else print("exception")

Another example:

return 1 if M otherwise 0

f = lambda x: 1 if x=="M" else 0

The thing to understand is that there's an update method for the Model and a separate update method for an Instance (record). Model.update() updates ALL matching records and returns an array see Sequelize documentation. Instance.update() updates the record and returns an instance object.

So to update a single record per the question, the code would look something like this:

SequlizeModel.findOne({where: {id: 'some-id'}})
.then(record => {
  
  if (!record) {
    throw new Error('No record found')
  }

  console.log(`retrieved record ${JSON.stringify(record,null,2)}`) 

  let values = {
    registered : true,
    email: '[email protected]',
    name: 'Joe Blogs'
  }
  
  record.update(values).then( updatedRecord => {
    console.log(`updated record ${JSON.stringify(updatedRecord,null,2)}`)
    // login into your DB and confirm update
  })

})
.catch((error) => {
  // do seomthing with the error
  throw new Error(error)
})

So, use Model.findOne() or Model.findByPkId() to get a handle a single Instance (record) and then use the Instance.update()

For file operations, Python uses the operating system's default buffering unless you configure it do otherwise. You can specify a buffer size, unbuffered, or line buffered.

For example, the open function takes a buffer size argument.

http://docs.python.org/library/functions.html#open

"The optional buffering argument specifies the file’s desired buffer size:"

• 0 means unbuffered,
• 1 means line buffered,
• any other positive value means use a buffer of (approximately) that size.
• A negative buffering means to use the system default, which is usually line buffered for tty devices and fully buffered for other files.
• If omitted, the system default is used.

code:

bufsize = 0
f = open('file.txt', 'w', buffering=bufsize)

The best source is probably Apple's official documentation. The specific variable you are looking for is CONFIGURATION.

If you want to catch the focus event dynamiclly on every input on your component :

import { AfterViewInit, Component, ElementRef } from '@angular/core';

@Component({
  selector: 'my-app',
  templateUrl: './app.component.html',
  styleUrls: [ './app.component.css' ]
})
export class AppComponent implements AfterViewInit {

  constructor(private el: ElementRef) {
  }

  ngAfterViewInit() {
       // document.getElementsByTagName('input') : to gell all Docuement imputs
       const inputList = [].slice.call((<HTMLElement>this.el.nativeElement).getElementsByTagName('input'));
        inputList.forEach((input: HTMLElement) => {
            input.addEventListener('focus', () => {
                input.setAttribute('placeholder', 'focused');
            });
            input.addEventListener('blur', () => {
                input.removeAttribute('placeholder');
            });
        });
    }
}

In Visual Studio .NET you can do Ctrl + K then C to comment, Crtl + K then U to uncomment a block.

A good way to check whether a python object is an instance of a type is to use isinstance() which is Python's 'built-in' function. For Python 3.6:

dct = {
       "1": "a", 
       "3": "b", 
       "8": {
            "12": "c", 
            "25": "d"
           }
      }

for key in dct.keys():
    if isinstance(dct[key], dict)== False:
       print(key, dct[key])
#shows:
# 1 a
# 3 b

Your problem..... I think is that your for loop is encompassing all of the if, else if stuff - which acts like one statement, like hoang nguyen pointed out.

Change to this. Note the brackets that denote the code block on which the for loop operates and the change of the first else if to if.

switch(value){

    case 1:
        for(int i=0; i<something_in_the_array.length;i++) {
            if(whatever_value==(something_in_the_array[i])) {
                value=2;
                break;
             }
        }

        if(whatever_value==2) {
            value=3;
            break;
        }
        else if(whatever_value==3) {
            value=4;
            break;
        }
        break;

Using Java 8's time API (assuming you are happy to get the year in your system's default time zone), you could use the Year::now method:

int year = Year.now().getValue();

My bible for JPA work is the Java Persistence wikibook. It has a section on unidirectional OneToMany which explains how to do this with a @JoinColumn annotation. In your case, i think you would want:

@OneToMany
@JoinColumn(name="TXTHEAD_CODE")
private Set<Text> text;

I've used a Set rather than a List, because the data itself is not ordered.

The above is using a defaulted referencedColumnName, unlike the example in the wikibook. If that doesn't work, try an explicit one:

@OneToMany
@JoinColumn(name="TXTHEAD_CODE", referencedColumnName="DATREG_META_CODE")
private Set<Text> text;

There are two problems with your code:

1. Use of wrong type

LocalDateTime does not support timezone. Given below is an overview of java.time types and you can see that the type which matches with your date-time string, 2016-12-01T23:00:00+00:00 is OffsetDateTime because it has a zone offset of +00:00.

Change your declaration as follows:

private OffsetDateTime startDate;

2. Use of wrong format

There are two problems with the format:

• You need to use y (year-of-era ) instead of Y (week-based-year). Check this discussion to learn more about it. In fact, I recommend you use u (year) instead of y (year-of-era ). Check this answer for more details on it.
• You need to use XXX or ZZZZZ for the offset part i.e. your format should be uuuu-MM-dd'T'HH:m:ssXXX.

Check the documentation page of DateTimeFormatter for more details about these symbols/formats.

Demo:

import java.time.OffsetDateTime;
import java.time.format.DateTimeFormatter;

public class Main {
    public static void main(String[] args) {
        String strDateTime = "2019-10-21T13:00:00+02:00";
        DateTimeFormatter dtf = DateTimeFormatter.ofPattern("uuuu-MM-dd'T'HH:m:ssXXX");
        OffsetDateTime odt = OffsetDateTime.parse(strDateTime, dtf);
        System.out.println(odt);
    }
}

Output:

2019-10-21T13:00+02:00

I'm surprised nobody has mentioned this excellent article: http://www.ee.columbia.edu/~dpwe/papers/PhamDN05-kmeans.pdf

After following several other suggestions I finally came across this article while reading this blog: https://datasciencelab.wordpress.com/2014/01/21/selection-of-k-in-k-means-clustering-reloaded/

After that I implemented it in Scala, an implementation which for my use cases provide really good results. Here's code:

import breeze.linalg.DenseVector
import Kmeans.{Features, _}
import nak.cluster.{Kmeans => NakKmeans}

import scala.collection.immutable.IndexedSeq
import scala.collection.mutable.ListBuffer

/*

class Kmeans(features: Features) {
  def fkAlphaDispersionCentroids(k: Int, dispersionOfKMinus1: Double = 0d, alphaOfKMinus1: Double = 1d): (Double, Double, Double, Features) = {
    if (1 == k || 0d == dispersionOfKMinus1) (1d, 1d, 1d, Vector.empty)
    else {
      val featureDimensions = features.headOption.map(_.size).getOrElse(1)
      val (dispersion, centroids: Features) = new NakKmeans[DenseVector[Double]](features).run(k)
      val alpha =
        if (2 == k) 1d - 3d / (4d * featureDimensions)
        else alphaOfKMinus1 + (1d - alphaOfKMinus1) / 6d
      val fk = dispersion / (alpha * dispersionOfKMinus1)
      (fk, alpha, dispersion, centroids)
    }
  }

  def fks(maxK: Int = maxK): List[(Double, Double, Double, Features)] = {
    val fadcs = ListBuffer[(Double, Double, Double, Features)](fkAlphaDispersionCentroids(1))
    var k = 2
    while (k <= maxK) {
      val (fk, alpha, dispersion, features) = fadcs(k - 2)
      fadcs += fkAlphaDispersionCentroids(k, dispersion, alpha)
      k += 1
    }
    fadcs.toList
  }

  def detK: (Double, Features) = {
    val vals = fks().minBy(_._1)
    (vals._3, vals._4)
  }
}

object Kmeans {
  val maxK = 10
  type Features = IndexedSeq[DenseVector[Double]]
}

A way that will fail if your input string isn't valid pairs of hex characters...:

Lot of good tips here, but inside Powershell I could not get it to work.

I am a .NET developer and we mainly still use Windows OS as we haven't made use of .Net core and cross platform so much, so my everyday use with Git is in a Windows environment, where the shell used is more often Powershell and not Git bash.

The following procedure can be followed to create an aliased function for adding untracked files in a Git repository.

Inside your $profile file of Powershell (in case it is missing - you can run: New-Item $Profile)

notepad $Profile

Now add this Powershell method:

function AddUntracked-Git() {
 &git ls-files -o --exclude-standard | select | foreach { git add $_ }
}

Save the $profile file and reload it into Powershell. Then reload your $profile file with: . $profile

This is similar to the source command in *nix environments IMHO.

So next time you, if you are developer using Powershell in Windows against Git repo and want to just include untracked files you can run:

AddUntracked-Git

This follows the Powershell convention where you have verb-nouns.

The default element value of any array of primitives is already zero: false for booleans.

you could do this, if you want to use the old syntax (or don't want to rewrite every template)

@for $i from 1 through $grid-columns {
  @include media-breakpoint-up(xs) {
    .col-xs-#{$i} {
      @include make-col-ready();
      @include make-col($i);
    }
  }
}

get_or_create() returns a tuple:

customer.source, created  = Source.objects.get_or_create(name="Website")

• created ? has a boolean value, is created or not.

• customer.source ? has an object of get_or_create() method.

I created this solution from the above suggestions mixed with microsofts solution of for iterating through a collection.

Public Function InCollection(col As Collection, Optional vItem, Optional vKey) As Boolean
On Error Resume Next

Dim vColItem As Variant

InCollection = False

If Not IsMissing(vKey) Then
    col.item vKey

    '5 if not in collection, it is 91 if no collection exists
    If Err.Number <> 5 And Err.Number <> 91 Then
        InCollection = True
    End If
ElseIf Not IsMissing(vItem) Then
    For Each vColItem In col
        If vColItem = vItem Then
            InCollection = True
            GoTo Exit_Proc
        End If
    Next vColItem
End If

Exit_Proc:
Exit Function
Err_Handle:
Resume Exit_Proc
End Function

API test automation, up to once per minute, is a service available through theRightAPI. You create your test scenarios, and execute them. Once those tests do what you expect them to, you can then schedule them. Tests can be 'chained' together for scenarios that require authentication. For example, you can have a test that make an OAuth request to Twitter, and creates a shared token that can then be used by any other test. Tests can also have validation criteria attached to ensure http status codes, or even detailed inspection of the responses using javascript or schema validation. Once tests are scheduled, you can then have alerts notify you as soon as a particular test fails validation, or is behaving out of established ranges for response time or response size.

As mentioned by @Vivek Solanki, I also uploaded my file on the colaboratory dashboard under "File" section. Just take a note of where the file has been uploaded. For me, train_data = pd.read_csv('/fileName.csv') worked.

If you are to replace a fixed string or some pattern, I would also like to add the bash builtin pattern string replacement variable substitution construct. Instead of describing it myself, I am quoting the section from the bash manual:

${parameter/pattern/string}

The pattern is expanded to produce a pattern just as in pathname expansion. parameter is expanded and the longest match of pattern against its value is replaced with string. If pattern begins with /, all matches of pattern are replaced with string. Normally only the first match is replaced. If pattern begins with #, it must match at the beginning of the expanded value of parameter. If pattern begins with %, it must match at the end of the expanded value of parameter. If string is null, matches of pattern are deleted and the / following pattern may be omitted. If parameter is @ or *, the substitution operation is applied to each positional parameter in turn, and the expansion is the resultant list. If parameter is an array variable subscripted with @ or *, the substitution operation is applied to each member of the array in turn, and the expansion is the resultant list.

Okay, important qualifier for this answer: The question does ask to use either rabbitmqctl OR rabbitmqadmin to solve this, my answer needed to use both. Also, note that this was tested on MacOS 10.12.6 and the versions of the rabbitmqctl and rabbitmqadmin that are installed when installing rabbitmq with Homebrew and which is identified with brew list --versions as rabbitmq 3.7.0

rabbitmqctl list_queues -p <VIRTUAL_HOSTNAME> name | sed 1,2d | xargs -I qname rabbitmqadmin --vhost <VIRTUAL_HOSTNAME> delete queue name=qname

I assume X and Y are arrays? If so, there's a very simple way to do this:

x = [1, 1, 2, 4]
y = [1, 2, 2, 2]

# intersection
x & y            # => [1, 2]

# union
x | y            # => [1, 2, 4]

# difference
x - y            # => [4]

Maybe

When the compiler compiles the class User and gets to the MyMessageBox line, MyMessageBox has not yet been defined. The compiler has no idea MyMessageBox exists, so cannot understand the meaning of your class member.

You need to make sure MyMessageBox is defined before you use it as a member. This is solved by reversing the definition order. However, you have a cyclic dependency: if you move MyMessageBox above User, then in the definition of MyMessageBox the name User won't be defined!

What you can do is forward declare User; that is, declare it but don't define it. During compilation, a type that is declared but not defined is called an incomplete type. Consider the simpler example:

struct foo; // foo is *declared* to be a struct, but that struct is not yet defined

struct bar
{
    // this is okay, it's just a pointer;
    // we can point to something without knowing how that something is defined
    foo* fp; 

    // likewise, we can form a reference to it
    void some_func(foo& fr);

    // but this would be an error, as before, because it requires a definition
    /* foo fooMember; */
};

struct foo // okay, now define foo!
{
    int fooInt;
    double fooDouble;
};

void bar::some_func(foo& fr)
{
    // now that foo is defined, we can read that reference:
    fr.fooInt = 111605;
    fr.foDouble = 123.456;
}

By forward declaring User, MyMessageBox can still form a pointer or reference to it:

class User; // let the compiler know such a class will be defined

class MyMessageBox
{
public:
    // this is ok, no definitions needed yet for User (or Message)
    void sendMessage(Message *msg, User *recvr); 

    Message receiveMessage();
    vector<Message>* dataMessageList;
};

class User
{
public:
    // also ok, since it's now defined
    MyMessageBox dataMsgBox;
};

You cannot do this the other way around: as mentioned, a class member needs to have a definition. (The reason is that the compiler needs to know how much memory User takes up, and to know that it needs to know the size of its members.) If you were to say:

class MyMessageBox;

class User
{
public:
    // size not available! it's an incomplete type
    MyMessageBox dataMsgBox;
};

It wouldn't work, since it doesn't know the size yet.

On a side note, this function:

 void sendMessage(Message *msg, User *recvr);

Probably shouldn't take either of those by pointer. You can't send a message without a message, nor can you send a message without a user to send it to. And both of those situations are expressible by passing null as an argument to either parameter (null is a perfectly valid pointer value!)

Rather, use a reference (possibly const):

 void sendMessage(const Message& msg, User& recvr);

There is really nice package with few examples of usage called axios-cancel. I've found it very helpful. Here is the link: https://www.npmjs.com/package/axios-cancel

Splitting an empty string with String.split() returns a single element array containing an empty string. In most cases you'd probably prefer to get an empty array, or a null if you passed in a null, which is exactly what you get with org.apache.commons.lang3.StringUtils.split(str).

import org.apache.commons.lang3.StringUtils;

StringUtils.split(null)       => null
StringUtils.split("")         => []
StringUtils.split("abc def")  => ["abc", "def"]
StringUtils.split("abc  def") => ["abc", "def"]
StringUtils.split(" abc ")    => ["abc"]

Another option is google guava Splitter.split() and Splitter.splitToList() which return an iterator and a list correspondingly. Unlike the apache version Splitter will throw an NPE on null:

import com.google.common.base.Splitter;

Splitter SPLITTER = Splitter.on(',').trimResults().omitEmptyStrings();

SPLITTER.split("a,b,   c , , ,, ")     =>  [a, b, c]
SPLITTER.split("")                     =>  []
SPLITTER.split("  ")                   =>  []
SPLITTER.split(null)                   =>  NullPointerException

If you want a list rather than an iterator then use Splitter.splitToList().

This is using the :hover pseudoelement in CSS3.

HTML:

<div id="wrapper">
    <img src="http://placehold.it/300x200" class="hover" />
    <p class="text">text</p>
</div>?

CSS:

#wrapper .text {
position:relative;
bottom:30px;
left:0px;
visibility:hidden;
}

#wrapper:hover .text {
visibility:visible;
}

?Demo HERE.

This instead is a way of achieving the same result by using jquery:

HTML:

<div id="wrapper">
    <img src="http://placehold.it/300x200" class="hover" />
    <p class="text">text</p>
</div>?

CSS:

#wrapper p {
position:relative;
bottom:30px;
left:0px;
visibility:hidden;
}

jquery code:

$('.hover').mouseover(function() {
  $('.text').css("visibility","visible");
});

$('.hover').mouseout(function() {
  $('.text').css("visibility","hidden");
});

You can put the jquery code where you want, in the body of the HTML page, then you need to include the jquery library in the head like this:

<head>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
</head>

You can see the demo HERE.

When you want to use it on your website, just change the <img src /> value and you can add multiple images and captions, just copy the format i used: insert image with class="hover" and p with class="text"

SELECT COUNT(*) FROM information_schema.tables WHERE table_schema = 'database_name';

You can use something like:

var nvc = Request.Unvalidated().Form;

Later, nvc["yourKey"] should work.

Thanks, that really clarified my thinking. Now here is (almost) 10 (almost) good reasons NOT to use getters and setters:

1. When you realize you need to do more than just set and get the value, you can just make the field private, which will instantly tell you where you've directly accessed it.
   
2. Any validation you perform in there can only be context free, which validation rarely is in practice.
   
3. You can change the value being set - this is an absolute nightmare when the caller passes you a value that they [shock horror] want you to store AS IS.
   
4. You can hide the internal representation - fantastic, so you're making sure that all these operations are symmetrical right?
   
5. You've insulated your public interface from changes under the sheets - if you were designing an interface and weren't sure whether direct access to something was OK, then you should have kept designing.
   
6. Some libraries expect this, but not many - reflection, serialization, mock objects all work just fine with public fields.
   
7. Inheriting this class, you can override default functionality - in other words you can REALLY confuse callers by not only hiding the implementation but making it inconsistent.
   

The last three I'm just leaving (N/A or D/C)...

simply put this at the end of your code:

while(1){ }

this function will keep going on forever(or until you close the console) and will keep the console it from closing on its own.

The better way of sending GET or POST requests with PHP is as below:

<?php
    $r = new HttpRequest('http://example.com/form.php', HttpRequest::METH_POST);
    $r->setOptions(array('cookies' => array('lang' => 'de')));
    $r->addPostFields(array('user' => 'mike', 'pass' => 's3c|r3t'));

    try {
        echo $r->send()->getBody();
    } catch (HttpException $ex) {
        echo $ex;
    }
?>

The code is taken from official documentation here http://docs.php.net/manual/da/httprequest.send.php

Two things. First I don't think you are adding the data that you want to pass to the fragment correctly. What you need to pass to the fragment is a bundle, not an intent. For example if I wanted send an int value to a fragment I would create a bundle, put the int into that bundle, and then set that bundle as an argument to be used when the fragment was created.

Bundle bundle = new Bundle();
bundle.putInt(key, value);
fragment.setArguments(bundle);

Second to retrieve that information you need to get the arguments sent to the fragment. You then extract the value based on the key you identified it with. For example in your fragment:

Bundle bundle = this.getArguments();
if (bundle != null) {
    int i = bundle.getInt(key, defaulValue);
}

What you are getting changes depending on what you put. Also the default value is usually null but does not need to be. It depends on if you set a default value for that argument.

Lastly I do not think you can do this in onCreateView. I think you must retrieve this data within your fragment's onActivityCreated method. My reasoning is as follows. onActivityCreated runs after the underlying activity has finished its own onCreate method. If you are placing the information you wish to retrieve within the bundle durring your activity's onCreate method, it will not exist during your fragment's onCreateView. Try using this in onActivityCreated and just update your ListView contents later.

This may not be the answer you are looking for, but may help others whose jquery is not working properly, or working sometimes and not at other times.

This could be because your jquery has not yet loaded and you have started to interact with the page. Either put jquery on top in head (probably not a very great idea) or use a loader or spinner to stop the user from interacting with the page until the entire jquery has loaded.

What @Darin said is what I would recommend as well. However I would add to it (and in response to one of the comments) that you can in fact also use this method for primitive types like bit, bool, even structures like Guid by simply making them nullable. Once you do this, the Required attribute functions as expected.

public UpdateViewView
{
    [Required]
    public Guid? Id { get; set; }
    [Required]
    public string Name { get; set; }
    [Required]
    public int? Age { get; set; }
    [Required]
    public bool? IsApproved { get; set; }
    //... some other properties
}

I think the easiest way to achieve this is by using set().

>>> x = [1,2,3,4,5,6,7,8,9,0]  
>>> y = [1,3,5,7,9]  
>>> list(set(x)- set(y))
[0, 2, 4, 6, 8]

you might also consider avoiding the core PHP module altogether.

It is quite common to use the guzzle json tools as a library in PHP apps these days. If your app is a composer app, it is trivial to include them as a part of a composer build. The guzzle tool, as a library, would be a turnkey replacement for the json tool, if you tell PHP to autoinclude the tool.

Future internet searchers:

For new browsers (as of 2018: Chrome, Firefox, Safari, Opera, Edge, and most mobile browsers, but not IE), fetch is a standard API that simplifies asynchronous network calls (for which we used to need XMLHttpRequest or jQuery's $.ajax).

Here is a traditional form:

<form id="myFormId" action="/api/process/form" method="post">
    <!-- form fields here -->
    <button type="submit">SubmitAction</button>
</form>

If a form like the above is handed to you (or you created it because it is semantic html), then you can wrap the fetch code in an event listener as below:

document.forms['myFormId'].addEventListener('submit', (event) => {
    event.preventDefault();
    // TODO do something here to show user that form is being submitted
    fetch(event.target.action, {
        method: 'POST',
        body: new URLSearchParams(new FormData(event.target)) // event.target is the form
    }).then((resp) => {
        return resp.json(); // or resp.text() or whatever the server sends
    }).then((body) => {
        // TODO handle body
    }).catch((error) => {
        // TODO handle error
    });
});

(Or, if like the original poster you want to call it manually without a submit event, just put the fetch code there and pass a reference to the form element instead of using event.target.)

Docs:

Fetch: https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API

Other: https://developer.mozilla.org/en-US/docs/Learn/HTML/Forms/Sending_forms_through_JavaScript That page in 2018 does not mention fetch (yet). But it mentions that the target="myIFrame" trick is deprecated. And it also has an example of form.addEventListener for the 'submit' event.

you can also do this

margin-top:-30px; 
min-height:40px;

this "help" to stop the div yanking everything up a bit.

https://docs.oracle.com/javase/tutorial/reflect/class/classMembers.html also has charts for locating methods and constructors.

All your problems are that you are mixing content type negotiation with parameter passing. They are things at different levels. More specific, for your question 2, you constructed the response header with the media type your want to return. The actual content negotiation is based on the accept media type in your request header, not response header. At the point the execution reaches the implementation of the method getPersonFormat, I am not sure whether the content negotiation has been done or not. Depends on the implementation. If not and you want to make the thing work, you can overwrite the request header accept type with what you want to return.

return new ResponseEntity<>(PersonFactory.createPerson(), httpHeaders, HttpStatus.OK);

you can use .css method of jquery..

please pay attention this code for upload image only. I use HTMLHelper for upload image. in cshtml file put this code

@using (Html.BeginForm("UploadImageAction", "Admin", FormMethod.Post, new { enctype = "multipart/form-data", id = "myUploadForm" }))
{
    <div class="controls">
       @Html.UploadFile("UploadImage")
    </div>
     <button class="button">Upload Image</button>
}

then create a HTMLHelper for Upload tag

public static class UploadHelper
{
public static MvcHtmlString UploadFile(this HtmlHelper helper, string name, object htmlAttributes = null)
{
    TagBuilder input = new TagBuilder("input");
    input.Attributes.Add("type", "file");
    input.Attributes.Add("id", helper.ViewData.TemplateInfo.GetFullHtmlFieldId(name));
    input.Attributes.Add("name", helper.ViewData.TemplateInfo.GetFullHtmlFieldName(name));

    if (htmlAttributes != null)
    {
        var attributes = HtmlHelper.AnonymousObjectToHtmlAttributes(htmlAttributes);
        input.MergeAttributes(attributes);
    }

    return new MvcHtmlString(input.ToString());
   }
}

and finally in Action Upload your file

        [AjaxOnly]
        [HttpPost]
        public ActionResult UploadImageAction(HttpPostedFileBase UploadImage)
        {
           string path = Server.MapPath("~") + "Files\\UploadImages\\" + UploadImage.FileName;
           System.Drawing.Image img = new Bitmap(UploadImage.InputStream);    
           img.Save(path);

           return View();
        }

Processing speed may not be the only relevant matter, however, as that's the question, here are some numbers in a benchmark: JSON vs. XML: Some hard numbers about verbosity. For the speed, in this simple benchmark, XML presents a 21% overhead over JSON.

An important note about the verbosity, which is as the article says, the most common complain: this is not so much relevant in practice (neither XML nor JSON data are typically handled by humans, but by machines), even if for the matter of speed, it requires some reasonable more time to compress.

Also, in this benchmark, a big amount of data was processed, and a typical web application won't transmit data chunks of such sizes, as big as 90MB, and compression may not be beneficial (for small enough data chunks, a compressed chunk will be bigger than the uncompressed chunk), so not applicable.

Still, if no compression is involved, JSON, as obviously terser, will weight less over the transmission channel, especially if transmitted through a WebSocket connection, where the absence of the classic HTTP overhead may make the difference at the advantage of JSON, even more significant.

After transmission, data is to be consumed, and this count in the overall processing time. If big or complex enough data are to be transmitted, the lack of a schema automatically checked for by a validating XML parser, may require more check on JSON data; these checks would have to be executed in JavaScript, which is not known to be particularly fast, and so it may present an additional overhead over XML in such cases.

Anyway, only testing will provides the answer for your particular use-case (if speed is really the only matter, and not standard nor safety nor integrity…).

Update 1: worth to mention, is EXI, the binary XML format, which offers compression at less cost than using Gzip, and save processing otherwise needed to decompress compressed XML. EXI is to XML, what BSON is to JSON. Have a quick overview here, with some reference to efficiency in both space and time: EXI: The last binary standard?.

Update 2: there also exists a binary XML performance reports, conducted by the W3C, as efficiency and low memory and CPU footprint, is also a matter for the XML area too: Efficient XML Interchange Evaluation.

Update 2015-03-01

Worth to be noticed in this context, as HTTP overhead was raised as an issue: the IANA has registered the EXI encoding (the efficient binary XML mentioned above), as a a Content Coding for the HTTP protocol (alongside with compress, deflate and gzip). This means EXI is an option which can be expected to be understood by browsers among possibly other HTTP clients. See Hypertext Transfer Protocol Parameters (iana.org).

My little contribution with this topic (https://gist.github.com/lucasferreira/a881606894dde5568029):

/* Autor: Lucas Ferreira - http://blog.lucasferreira.com | Usage: fz(9) or fz(100, 7) */
function fz(o, s) {
    for(var s=Math.max((+s||2),(n=""+Math.abs(o)).length); n.length<s; (n="0"+n));
    return (+o < 0 ? "-" : "") + n;
};

Usage:

fz(9) & fz(9, 2) == "09"
fz(-3, 2) == "-03"
fz(101, 7) == "0000101"

I know, it's a pretty dirty function, but it's fast and works even with negative numbers ;)

Have a look at this answer:

I am creating an installer that runs as a Java JAR file and it needs to unpack WAR and JAR files into appropriate places in the installation directory. The dependency plugin can be used in the package phase with the copy goal and it will download any file in the Maven repository (including WAR files) and write them where ever you need them. I changed the output directory to ${project.build.directory}/classes and then end result is that the normal JAR task includes my files just fine. I can then extract them and write them into the installation directory.

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
    <execution>
        <id>getWar</id>
        <phase>package</phase>
        <goals>
            <goal>copy</goal>

                </artifactItem>
            </artifactItems>
            <outputDirectory>${project.build.directory}/classes</outputDirectory>
        </configuration>
    </execution>

I had this error returned after using the commit id from a pull request commit id tab. That commit was subsequently squashed and merged. In the github pull request, look for this text: "merged commit xxxxxxx into..." instead of attempting to use the commit ids from the commits tab.

In case anyone else runs into this problem, I was able to get it working like this:

var path = require('path');
// ...
resolve: {
  root: [path.resolve(__dirname, 'src'), path.resolve(__dirname, 'node_modules')],
  extensions: ['', '.js']
};

where my directory structure is:

.
+-- dist
+-- node_modules
+-- package.json
+-- README.md
+-- src
¦   +-- components
¦   +-- index.html
¦   +-- main.js
¦   +-- styles
+-- webpack.config.js

Then from anywhere in the src directory I can call:

import MyComponent from 'components/MyComponent';

This can be caused if the client is in a different domain than the server.

I encountered this when testing one of my applications from my PC(client) to my (cloud) testing server and the simplest solution i could think of was setting up a vpn.

It has to do with the order in which bytes are stored in memory. The decimal number 5001 is 0x1389 in hexadecimal, so the bytes involved are 0x13 and 0x89. Many devices store numbers in little-endian format, meaning that the least significant byte comes first. So in this particular example it means that in memory the number 5001 will be stored as

0x89 0x13

The htons() function makes sure that numbers are stored in memory in network byte order, which is with the most significant byte first. It will therefore swap the bytes making up the number so that in memory the bytes will be stored in the order

0x13 0x89

On a little-endian machine, the number with the swapped bytes is 0x8913 in hexadecimal, which is 35091 in decimal notation. Note that if you were working on a big-endian machine, the htons() function would not need to do any swapping since the number would already be stored in the right way in memory.

The underlying reason for all this swapping has to do with the network protocols in use, which require the transmitted packets to use network byte order.

Use the CSS pointer-events:none on fields you want to "disable" (possibly together with a greyed background) which allows the POST action, like:

<input type="text" class="disable">

.disable{
pointer-events:none;
background:grey;
}

Ref: https://developer.mozilla.org/en-US/docs/Web/CSS/pointer-events

I was just inspired by your solution and tried another way.

Please try to add tableView.reloadData() to viewDidAppear().

This works for me.

I think the things behind scrolling is "the same" as reloadData. When you scroll the screen, it's like calling reloadData() when viewDidAppear .

If this works, plz reply this answer so I could be sure of this solution.

Here is another simple answer, but without using classes.

from tkinter import *


def raise_frame(frame):
    frame.tkraise()

root = Tk()

f1 = Frame(root)
f2 = Frame(root)
f3 = Frame(root)
f4 = Frame(root)

for frame in (f1, f2, f3, f4):
    frame.grid(row=0, column=0, sticky='news')

Button(f1, text='Go to frame 2', command=lambda:raise_frame(f2)).pack()
Label(f1, text='FRAME 1').pack()

Label(f2, text='FRAME 2').pack()
Button(f2, text='Go to frame 3', command=lambda:raise_frame(f3)).pack()

Label(f3, text='FRAME 3').pack(side='left')
Button(f3, text='Go to frame 4', command=lambda:raise_frame(f4)).pack(side='left')

Label(f4, text='FRAME 4').pack()
Button(f4, text='Goto to frame 1', command=lambda:raise_frame(f1)).pack()

raise_frame(f1)
root.mainloop()

You can create a function:

CREATE FUNCTION dbo.[Check_existance_of_carriage_return_line_feed]
(
      @String VARCHAR(MAX)
)
RETURNS VARCHAR(MAX)
BEGIN
DECLARE @RETURN_BOOLEAN INT

;WITH N1 (n) AS (SELECT 1 UNION ALL SELECT 1),
N2 (n) AS (SELECT 1 FROM N1 AS X, N1 AS Y),
N3 (n) AS (SELECT 1 FROM N2 AS X, N2 AS Y),
N4 (n) AS (SELECT ROW_NUMBER() OVER(ORDER BY X.n)
FROM N3 AS X, N3 AS Y)

SELECT @RETURN_BOOLEAN =COUNT(*)
FROM N4 Nums
WHERE Nums.n<=LEN(@String) AND ASCII(SUBSTRING(@String,Nums.n,1)) 
IN (13,10)    

RETURN (CASE WHEN @RETURN_BOOLEAN >0 THEN 'TRUE' ELSE 'FALSE' END)
END
GO

Then you can simple run a query like this:

SELECT column_name, dbo.[Check_existance_of_carriage_return_line_feed] (column_name)
AS [Boolean]
FROM [table_name]

The page sizes are looking different in your PDF because the images were originally set to different DPI (even if images are identical HxW in pixels). The good news is - it's only a display issue - and can be fixed easily.

An image with a higher DPI value would display smaller in a PDF (displays at the 'print-size' of the image). To avoid this, open each image in an image editor like GIMP or Photoshop. Open relevant image print control dialog box and set a suitable uniform DPI info for all the images. Remake the PDF with these new images. If in the new PDF images are too big - redo the DPI setting for each to a higher value. If in the new PDF pages are too small to read on-screen without zooming, again - redo DPI adjustment, this time put a lower DPI value. Ideally, 150 DPI should be good enough for images of 2500X2500 pixel - on a 17 inch monitor set to 1366x768 resolution.

BTW, the PDF file shall print each page at the specified DPI of that page. If all images are same DPI, you'll get a uniform printing.

Hope this helps :)

For increased performance you should not evaluate the dataframe using your predicate. You can just use the outcome of your predicate directly as illustrated below:

In [1]: import pandas as pd
        import numpy as np
        df = pd.DataFrame(np.random.randn(20,4),columns=list('ABCD'))


In [2]: df.head()
Out[2]:
          A         B         C         D
0 -2.019868  1.227246 -0.489257  0.149053
1  0.223285 -0.087784 -0.053048 -0.108584
2 -0.140556 -0.299735 -1.765956  0.517803
3 -0.589489  0.400487  0.107856  0.194890
4  1.309088 -0.596996 -0.623519  0.020400

In [3]: %time sum((df['A']>0) & (df['B']>0))
CPU times: user 1.11 ms, sys: 53 µs, total: 1.16 ms
Wall time: 1.12 ms
Out[3]: 4

In [4]: %time len(df[(df['A']>0) & (df['B']>0)])
CPU times: user 1.38 ms, sys: 78 µs, total: 1.46 ms
Wall time: 1.42 ms
Out[4]: 4

Keep in mind that this technique only works for counting the number of rows that comply with your predicate.

Hopefully working code (didn't do much testing):

function toFixed(value, precision) {
    var precision = precision || 0,
        neg = value < 0,
        power = Math.pow(10, precision),
        value = Math.round(value * power),
        integral = String((neg ? Math.ceil : Math.floor)(value / power)),
        fraction = String((neg ? -value : value) % power),
        padding = new Array(Math.max(precision - fraction.length, 0) + 1).join('0');

    return precision ? integral + '.' +  padding + fraction : integral;
}

You could also do it via jQuery:

$('#x_Created').addClass(date);

You can't with inline styling alone. Do not recommend reimplementing CSS features in JavaScript we already have a language that is extremely powerful and incredibly fast built for this use case -- CSS. So use it! Made Style It to assist.

You can just create your own .white class and add it to the glyphicon element.

.white, .white a {
  color: #fff;
}

<i class="glyphicon glyphicon-home white"></i>

If other whitespace characters are possible, then you'd want:

testString.split("\\s+");

I came here with a similar question/problem, but I only needed a single value to be stored from the query, not an array/table of results as in the orig post. I was able to use the table method above for a single value, however I have stumbled upon an easier way to store a single value.

declare @myVal int; set @myVal = isnull((select a from table1), 0);

Make sure to default the value in the isnull statement to a valid type for your variable, in my example the value in table1 that we're storing is an int.

Try this

button.addTarget(self, action:#selector(handleRegister()), for: .touchUpInside). 

Just add parenthesis with name of method.

Also you can refer link : Value of type 'CustomButton' has no member 'touchDown'

PycURL does this beautifully.

Below is a short example. It will throw a pycurl.error if something is fishy, where you get a tuple with error code and a human readable message.

import pycurl

curl = pycurl.Curl()
curl.setopt(pycurl.CAINFO, "myFineCA.crt")
curl.setopt(pycurl.SSL_VERIFYPEER, 1)
curl.setopt(pycurl.SSL_VERIFYHOST, 2)
curl.setopt(pycurl.URL, "https://internal.stuff/")

curl.perform()

You will probably want to configure more options, like where to store the results, etc. But no need to clutter the example with non-essentials.

Example of what exceptions might be raised:

(60, 'Peer certificate cannot be authenticated with known CA certificates')
(51, "common name 'CN=something.else.stuff,O=Example Corp,C=SE' does not match 'internal.stuff'")

Some links that I found useful are the libcurl-docs for setopt and getinfo.

Another cause for this might be case-insensitive file systems. If you have multiple folders in your repo on the same level whose names only differ by case, you will get hit by this. Browse the source repository using its web interface (e.g. GitHub or VSTS) to make sure.

By "camera position," it sounds like you want to adjust the elevation and the azimuth angle that you use to view the 3D plot. You can set this with ax.view_init. I've used the below script to first create the plot, then I determined a good elevation, or elev, from which to view my plot. I then adjusted the azimuth angle, or azim, to vary the full 360deg around my plot, saving the figure at each instance (and noting which azimuth angle as I saved the plot). For a more complicated camera pan, you can adjust both the elevation and angle to achieve the desired effect.

    from mpl_toolkits.mplot3d import Axes3D
    ax = Axes3D(fig)
    ax.scatter(xx,yy,zz, marker='o', s=20, c="goldenrod", alpha=0.6)
    for ii in xrange(0,360,1):
        ax.view_init(elev=10., azim=ii)
        savefig("movie%d.png" % ii)

New function "across" was introduced in dplyr version 1.0.0. The new function will supersede scoped variables (_if, _at, _all). Here's the official documentation

library(dplyr)
bob <- bob %>% 
       mutate(across(where(is.factor), as.character))

using keep_default_na=False should help you:

df = pd.read_csv(filename, keep_default_na=False)

<Directory /uploads>
   Options +Indexes
</Directory>

regex solution (The best way is the solution by @Elazar this is just for fun)

import re
def remove_prefix(text, prefix):
    return re.sub(r'^{0}'.format(re.escape(prefix)), '', text)

>>> print remove_prefix('template.extensions', 'template.')
extensions

A quick stab came up with:

Select (select count(*) from Table1) as Count1, (select count(*) from Table2) as Count2

Note: I tested this in SQL Server, so From Dual is not necessary (hence the discrepancy).

The opensource framework Dynamitey has a static method that does late binding using DLR including cast conversion among others.

dynamic Cast(object obj, Type castTo){
    return Dynamic.InvokeConvert(obj, castTo, explict:true);
}

The advantage of this over a Cast<T> called using reflection, is that this will also work for any IDynamicMetaObjectProvider that has dynamic conversion operators, ie. TryConvert on DynamicObject.

If anyone like me is still unable to register ASP.NET with IIS.

You just need to run these three commands one by one in command prompt

cd c:\windows\Microsoft.Net\Framework\v2.0.50727

after that, Run

aspnet_regiis.exe -i -enable

and Finally Reset IIS

iisreset

Hope it helps the person in need... cheers!

In the form described by you, the problem is tough. Do you consider copy, paste of part of the image into another larger image as a copy ? etc.

If you take a step-back, this is easier to solve if you watermark the master images. You will need to use a watermarking scheme to embed a code into the image. To take a step back, as opposed to some of the low-level approaches (edge detection etc) suggested by some folks, a watermarking method is superior because:

It is resistant to Signal processing attacks ? Signal enhancement – sharpening, contrast, etc. ? Filtering – median, low pass, high pass, etc. ? Additive noise – Gaussian, uniform, etc. ? Lossy compression – JPEG, MPEG, etc.

It is resistant to Geometric attacks ? Affine transforms ? Data reduction – cropping, clipping, etc. ? Random local distortions ? Warping

Do some research on watermarking algorithms and you will be on the right path to solving your problem. ( Note: You can benchmark you method using the STIRMARK dataset. It is an accepted standard for this type of application.

There are two cases you deal with when working with images in Android:

1. You want to load an image for your device density and you are going to use it “as is”, without changing its actual size. In this case you should work with drawables and Android will give you the best fitting image.
2. You want to load an image for your device density, but this image is going to be scaled up or down. For instance this is needed when you want to show a bigger launcher icon, or you have an animation, which increases image’s size. In such cases, to ensure best image quality, you should put your image into mipmap folder. What Android will do is, it will try to pick up the image from a higher density bucket instead of scaling it up.

SO

Thus, the rule of thumb to decide where to put your image into would be:

1. Launcher icons always go into mipmap folder.

2. Images, which are often scaled up (or extremely scaled down) and whose quality is critical for the app, go into mipmap folder as well.

3. All other images are usual drawables.

Now this is a very old thread i've come across but as many have pushed their answer's, here is mine in a hope to help someone with this simple code.

var search_value = "This is a dummy sentence!";_x000D_
var letter = 'a'; /*Can take any letter, have put in a var if anyone wants to use this variable dynamically*/_x000D_
letter = letter && "string" === typeof letter ? letter : "";_x000D_
var count;_x000D_
for (var i = count = 0; i < search_value.length; count += (search_value[i++] == letter));_x000D_
console.log(count);

I'm not sure if it is the fastest solution but i preferred it for simplicity and for not using regex (i just don't like using them!)

A Pending Intent is a token you give to some app to perform an action on your apps' behalf irrespective of whether your application process is alive or not.

I think the documentation is sufficiently detailed: Pending Intent docs.

Just think of use-cases for Pending Intents like (Broadcasting Intents, scheduling alarms) and the documentation will become clearer and meaningful.

It is to do with file permissions and it happens on systems that have the suphp(usually cpanel/whost servers) installed.

Removing the write permission from anyone else but the owner(644|600) for the php files will fix the issue. That is how i got it fixed.

I hope this helps.

yum list installed | grep mysql

Then if it's not installed you can do (as root)

yum install mysql -y

In simple way, Its not possible. Because DropdownList contain ListItem and it will be selected by default

But, you can use ValidationControl for that:

<asp:RequiredFieldValidator InitialValue="-1" ID="Req_ID" Display="Dynamic" 
ValidationGroup="g1" runat="server" ControlToValidate="ControlID"
Text="*" ErrorMessage="ErrorMessage"></asp:RequiredFieldValidator>

It's simple and follow the small Steps to proceed:

• Install git on the remote server say some ec2 instance
• Now create a project folder `$mkdir project.git
• $cd project and execute $git init --bare

Let's say this project.git folder is present at your ip with address inside home_folder/workspace/project.git, forex- ec2 - /home/ubuntu/workspace/project.git

Now in your local machine, $cd into the project folder which you want to push to git execute the below commands:

• git init .

• git remote add origin [email protected]:/home/ubuntu/workspace/project.git

• git add .
• git commit -m "Initial commit"

Below is an optional command but found it has been suggested as i was working to setup the same thing

git config --global remote.origin.receivepack "git receive-pack"

• git pull origin master
• git push origin master

This should work fine and will push the local code to the remote git repository.

To check the remote fetch url, cd project_folder/.git and cat config, this will give the remote url being used for pull and push operations.

You can also use an alternative way, after creating the project.git folder on git, clone the project and copy the entire content into that folder. Commit the changes and it should be the same way. While cloning make sure you have access or the key being is the secret key for the remote server being used for deployment.

Following the answer of @Even Mien I have tried to go a bit further and make it Generic, I seem to be almost there but one case still resist and I probably can simplify my code a bit.
I post it here if anyone see how I could improve and especially make it works as I can't assign it from a string

So Far I have the following results:

        Console.WriteLine(TestEnum.Test1);//displays "TEST1"

        bool test = "TEST1" == TestEnum.Test1; //true

        var test2 = TestEnum.Test1; //is TestEnum and has value

        string test3 = TestEnum.Test1; //test3 = "TEST1"

        var test4 = TestEnum.Test1 == TestEnum.Test2; //false
         EnumType<TestEnum> test5 = "TEST1"; //works fine

        //TestEnum test5 = "string"; DOESN'T compile .... :(:(

Where the magics happens :

public abstract  class EnumType<T>  where T : EnumType<T>   
{

    public  string Value { get; set; }

    protected EnumType(string value)
    {
        Value = value;
    }


    public static implicit operator EnumType<T>(string s)
    {
        if (All.Any(dt => dt.Value == s))
        {
            Type t = typeof(T);

            ConstructorInfo ci = t.GetConstructor(BindingFlags.Instance | BindingFlags.NonPublic,null, new Type[] { typeof(string) }, null);

            return (T)ci.Invoke(new object[] {s});
        }
        else
        {
            return null;
        }
    }

    public static implicit operator string(EnumType<T> dt)
    {
        return dt?.Value;
    }


    public static bool operator ==(EnumType<T> ct1, EnumType<T> ct2)
    {
        return (string)ct1 == (string)ct2;
    }

    public static bool operator !=(EnumType<T> ct1, EnumType<T> ct2)
    {
        return !(ct1 == ct2);
    }


    public override bool Equals(object obj)
    {
        try
        {
            return (string)obj == Value;
        }
        catch
        {
            return false;
        }
    }

    public override int GetHashCode()
    {
        return Value.GetHashCode();
    }

    public static IEnumerable<T> All
     => typeof(T).GetProperties()
       .Where(p => p.PropertyType == typeof(T))
       .Select(x => (T)x.GetValue(null, null));



}

I only then have to declare this for my enums:

public class TestEnum : EnumType<TestEnum> 
{

    private TestEnum(string value) : base(value)
    {}

    public static TestEnum Test1 { get { return new TestEnum("TEST1"); } }
    public static TestEnum Test2 { get { return new TestEnum("TEST2"); } }
}

You'll need to use the FileSystem object and perform some logic on the resultant FileStatus objects to manually recurse into the subdirectories.

You can also apply a PathFilter to only return the xml files using the listStatus(Path, PathFilter) method

The hadoop FsShell class has examples of this for the hadoop fs -lsr command, which is a recursive ls - see the source, around line 590 (the recursive step is triggered on line 635)

If you check Thrown for Common Language Runtime Exception in the break when an exception window (Ctrl+Alt+E in Visual Studio), then the execution should break while you are debugging when the exception is thrown.

This will probably give you some insight into what is going on.

You can use GNU awk:

$ cat hta
RewriteCond %{HTTP_HOST} !^www\.mysite\.net$
RewriteRule (.*) http://www.mysite.net/$1 [R=301,L]

$ gawk 'match($0, /.*(http.*?)\$/, m) { print m[1]; }' < hta
http://www.mysite.net/

Open gradle-wrapper.properties

distributionUrl=https\://services.gradle.org/distributions/gradle-3.3-all.zip

change it to

distributionUrl=https\://services.gradle.org/distributions/gradle-4.4-all.zip

Use a regular expression validator instead. This will work on the client side using JavaScript, but also when JavaScript is disabled (as the length check will be performed on the server as well).

The following example checks that the entered value is between 0 and 100 characters long:

<asp:RegularExpressionValidator runat="server" ID="valInput"
    ControlToValidate="txtInput"
    ValidationExpression="^[\s\S]{0,100}$"
    ErrorMessage="Please enter a maximum of 100 characters"
    Display="Dynamic">*</asp:RegularExpressionValidator>

There are of course more complex regexs you can use to better suit your purposes.

A late answer but I hope it will help anyone visiting here later too..

I will provide categories to save and their respective best methods...

1. Shared Preferences Use this when storing simple values on storage e.g Color theme, app language, last scroll position(in reading apps).. these are simple settings that you would want to persist when the app restarts.. You could, however, use this to store large things(Lists, Maps, Images) but that would require serialization and deserialization.. To learn more on this deserialization and serialization go here.
2. Files This helps a lot when you have data that is defined more by you for example log files, image files and maybe you want to export csv files.. I heard that this type of persistence can be washed by storage cleaners once disk runs out of space.. Am not sure as i have never seen it.. This also can store almost anything but with the help of serialization and deserialization..
3. Saving to a database This is enormously helpful in data which is a bit complex. And I think this doesn't get washed up by disc cleaners as it is stored in AppData(for android).. In this, your data is stored in an SQLite database. Its plugin is SQFLite. Kinds of data that you might wanna put in here are like everything that can be represented by a database.

componentDidUpdate(){               
    $(".wpcf7-submit").click( function(event) {
        event.preventDefault();
    })
}

You can use componentDidUpdate and event.preventDefault() to disable form submission.As react does not support return false.

I would suggest not to use list-style-image, as it behaves quite differently in different browsers, especially the image position

instead, you can use something like this

ol.widgets,
ol.widgets li { list-style: none; }
ol.widgets li { padding-left: 20px; backgroud: transparent ("image") no-repeat x y; }

it works in all browsers and would give you the identical result in different browsers.

I want to extend Olcay's nice answer. His approach is good, your login page controller should be like this to put the referrer url into session:

@RequestMapping(value = "/login", method = RequestMethod.GET)
public String loginPage(HttpServletRequest request, Model model) {
    String referrer = request.getHeader("Referer");
    request.getSession().setAttribute("url_prior_login", referrer);
    // some other stuff
    return "login";
}

And you should extend SavedRequestAwareAuthenticationSuccessHandler and override its onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) method. Something like this:

public class MyCustomLoginSuccessHandler extends SavedRequestAwareAuthenticationSuccessHandler {
    public MyCustomLoginSuccessHandler(String defaultTargetUrl) {
        setDefaultTargetUrl(defaultTargetUrl);
    }

    @Override
    public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws ServletException, IOException {
        HttpSession session = request.getSession();
        if (session != null) {
            String redirectUrl = (String) session.getAttribute("url_prior_login");
            if (redirectUrl != null) {
                // we do not forget to clean this attribute from session
                session.removeAttribute("url_prior_login");
                // then we redirect
                getRedirectStrategy().sendRedirect(request, response, redirectUrl);
            } else {
                super.onAuthenticationSuccess(request, response, authentication);
            }
        } else {
            super.onAuthenticationSuccess(request, response, authentication);
        }
    }
}

Then, in your spring configuration, you should define this custom class as a bean and use it on your security configuration. If you are using annotation config, it should look like this (the class you extend from WebSecurityConfigurerAdapter):

@Bean
public AuthenticationSuccessHandler successHandler() {
    return new MyCustomLoginSuccessHandler("/yourdefaultsuccessurl");
}

In configure method:

@Override
protected void configure(HttpSecurity http) throws Exception {
    http
            // bla bla
            .formLogin()
                .loginPage("/login")
                .usernameParameter("username")
                .passwordParameter("password")
                .successHandler(successHandler())
                .permitAll()
            // etc etc
    ;
}

An addition to the answer: when you do not want to list the folders, only the files in the subfolders, use /A-D switch like this:

dir ..\myfolder /b /s /A-D /o:gn>list.txt

2. Click gear icon on bottom right
3. In General section, check or uncheck "Show user agent styles".

Keep in mind that SQL strings can not be larger than 4000 bytes, while Pl/SQL can have strings as large as 32767 bytes. see below for an example of inserting a large string via an anonymous block which I believe will do everything you need it to do.

note I changed the varchar2(32000) to CLOB

set serveroutput ON 
CREATE TABLE testclob 
  ( 
     id NUMBER, 
     c  CLOB, 
     d  VARCHAR2(4000) 
  ); 

DECLARE 
    reallybigtextstring CLOB := '123'; 
    i                   INT; 
BEGIN 
    WHILE Length(reallybigtextstring) <= 60000 LOOP 
        reallybigtextstring := reallybigtextstring 
                               || '000000000000000000000000000000000'; 
    END LOOP; 

    INSERT INTO testclob 
                (id, 
                 c, 
                 d) 
    VALUES     (0, 
                reallybigtextstring, 
                'done'); 

    dbms_output.Put_line('I have finished inputting your clob: ' 
                         || Length(reallybigtextstring)); 
END; 

/ 
SELECT * 
FROM   testclob; 


 "I have finished inputting your clob: 60030"

If anyone change their existing package name then sometimes it makes problem like that, so you should change local package name, build.gradle file package name and if your project have any google-services.json file then simply you need to change your JSON file package name too.

Old File look like that

"client": [
{
  "client_info": {
    "mobilesdk_app_id": "1:517104510151:android:8b7ed3989db24a6f928ae2",
    "android_client_info": {
      "package_name": "com.techsajib.oldapp"
    }
  },

New File look like that

"client": [
{
  "client_info": {
    "mobilesdk_app_id": "1:517104510151:android:8b7ed3989db24a6f928ae2",
    "android_client_info": {
      "package_name": "com.techsajib.newapp"
    }
  },

Note: sometimes JSON file have several package name so change all of them

go get will install the package in the first directory listed at GOPATH (an environment variable which might contain a colon separated list of directories). You can use go get -u to update existing packages.

You can also use go get -u all to update all packages in your GOPATH

For larger projects, it might be reasonable to create different GOPATHs for each project, so that updating a library in project A wont cause issues in project B.

Type go help gopath to find out more about the GOPATH environment variable.

just change this line

[img setImage:[UIImage imageNamed:@"anyImageName"]];

with following line

img = [UIImage imageNamed:@"anyImageName"];

Put variables that will be changed by your interaction at extraData

You can be creative.

For example if you are dealing with a changing list with checkboxes on them.

<FlatList
      data={this.state.data.items}
      extraData={this.state.data.items.length * (this.state.data.done.length + 1) }
      renderItem={({item}) => <View>  

You can use ref.

import ChildForm from './components/ChildForm'

new Vue({
  el: '#app',
  data: {
    item: {}
  },
  template: `
  <div>
     <ChildForm :item="item" ref="form" />
     <button type="submit" @click.prevent="submit">Post</button>
  </div>
  `,
  methods: {
    submit() {
      this.$refs.form.submit()
    }
  },
  components: { ChildForm },
})

If you dislike tight coupling, you can use Event Bus as shown by @Yosvel Quintero. Below is another example of using event bus by passing in the bus as props.

import ChildForm from './components/ChildForm'

new Vue({
  el: '#app',
  data: {
    item: {},
    bus: new Vue(),
  },
  template: `
  <div>
     <ChildForm :item="item" :bus="bus" ref="form" />
     <button type="submit" @click.prevent="submit">Post</button>
  </div>
  `,
  methods: {
    submit() {
      this.bus.$emit('submit')
    }
  },
  components: { ChildForm },
})

Code of component.

<template>
 ...
</template>

<script>
export default {
  name: 'NowForm',
  props: ['item', 'bus'],
  methods: {
    submit() {
        ...
    }
  },
  mounted() {
    this.bus.$on('submit', this.submit)
  },  
}
</script>

Windows:

1. in File Win/Users/HOME/.gitconfig set mergetool.keepTemporaries=false
2. in File git/libexec/git-core/git-mergetool, in the function cleanup_temp_files() add rm -rf -- "$MERGED.orig" within the else block.

asp:TextBox ID="txtName" placeholder="any text here"

Using the {# #} notation, like so:

{# Everything you see here is a comment. It won't show up in the HTML output. #}

Just try below a simple solution:

JsonObject body=new JsonObject();
body.add("orders", (JsonElement) orders);

whenever my JSON request is like:

{
      "role": "RT",
      "orders": [
        {
          "order_id": "ORDER201908aPq9Gs",
          "cart_id": 164444,
          "affiliate_id": 0,
          "orm_order_status": 9,
          "status_comments": "IC DUE - Auto moved to Instruction Call Due after 48hrs",
          "status_date": "2020-04-15",
        }
      ]
    }

It might be possible that the file you are accessing has a swap copy (or swap version) already there in the same directory

Hence first see whether a hidden file exists or not.

For example, see for the following type of files

.system.conf.swp

By using the command

ls -a

And then, delete it using ...

rm .system.conf.swp

Usually, I recommend to start using super user privileges using ...

sudo su

If you have made that request in your application already, and see it logged in Google Dev Tools, you can use the copy cURL command from the context menu when right-clicking on the request in the network tab. Copy -> Copy as cURL. It will contain all headers, cookies, etc..

Actually, I was also having the same problem. I was running Ubuntu. Mine problem arises because I'd lost my public key of the Ubuntu. Even updating my system was not happening. It was giving GPG error. In that case, you can regain your key by using this command:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys <key in GPG error>

After that npm works fine!

Your command line should look like this:

rsync -rvz -e 'ssh -p 2222' --progress ./dir user@host:/path

this works fine - I use it all the time without needing any new firewall rules - just note the SSH command itself is enclosed in quotes.

most decent firewall programs should allow you to access this information. I know that Agnitum OutpostPro Firewall does.

after a lot of tries, I've read in other topics which someone said "delete all your apps and create it again". I did that but, as you can imagine, a new App will create a new Application ID on Facebook's page.

So, even after all the "set public things" it didn't work because the application ID was wrong in my code due to the creation of a new App on Facebook developer page.

So, as AndrewSmiley said above, you should remeber to update that in your app @strings

Here is the typical structure of new Codeigniter project:

- application/
- system/
- user_guide/
- index.php <- this is the file you need to change

I usually use this code in my CI index.php. Just change local_server_name to the name of your local webserver.

With this code you can deploy your site to your production server without changing index.php each time.

// Domain-based environment
if ($_SERVER['SERVER_NAME'] == 'local_server_name') {
    define('ENVIRONMENT', 'development');
} else {
    define('ENVIRONMENT', 'production');
}

/*
 *---------------------------------------------------------------
 * ERROR REPORTING
 *---------------------------------------------------------------
 *
 * Different environments will require different levels of error reporting.
 * By default development will show errors but testing and live will hide them.
 */

if (defined('ENVIRONMENT')) {
    switch (ENVIRONMENT) {
        case 'development':
            error_reporting(E_ALL);
            break;
        case 'testing':
        case 'production':
            error_reporting(0);
            ini_set('display_errors', 0);  
            break;
        default:
            exit('The application environment is not set correctly.');
    }
}

1. git rm --cached remove_file
2. add file to gitignore
3. git add .gitignore
4. git commit -m "Excluding"
5. Have fun ;)

I wrote an article on topis how to [manually install curl on debian linu][1]x.

[1]: http://www.jasom.net/how-to-install-curl-command-manually-on-debian-linux. This is its shortcut:

1. cd /usr/local/src
2. wget http://curl.haxx.se/download/curl-7.36.0.tar.gz
3. tar -xvzf curl-7.36.0.tar.gz
4. rm *.gz
5. cd curl-7.6.0
6. ./configure
7. make
8. make install

And restart Apache. If you will have an error during point 6, try to run apt-get install build-essential.

It's as simple as this:

git reset HEAD^

Note: some shells treat ^ as a special character (for example some Windows shells or ZSH with globbing enabled), so you may have to quote "HEAD^" in those cases.

git reset without a --hard or --soft moves your HEAD to point to the specified commit, without changing any files. HEAD^ refers to the (first) parent commit of your current commit, which in your case is the commit before the temporary one.

Note that another option is to carry on as normal, and then at the next commit point instead run:

git commit --amend [-m … etc]

which will instead edit the most recent commit, having the same effect as above.

Note that this (as with nearly every git answer) can cause problems if you've already pushed the bad commit to a place where someone else may have pulled it from. Try to avoid that

SI = Source Index
DI = Destination Index

As others have indicated, they have special uses with the string instructions. For real mode programming, the ES segment register must be used with DI and DS with SI as in

movsb  es:di, ds:si

SI and DI can also be used as general purpose index registers. For example, the C source code

srcp [srcidx++] = argv [j];

compiles into

8B550C         mov    edx,[ebp+0C]
8B0C9A         mov    ecx,[edx+4*ebx]
894CBDAC       mov    [ebp+4*edi-54],ecx
47             inc    edi

where ebp+12 contains argv, ebx is j, and edi has srcidx. Notice the third instruction uses edi mulitplied by 4 and adds ebp offset by 0x54 (the location of srcp); brackets around the address indicate indirection.

AX = accumulator
DX = double word accumulator
CX = counter
BX = base register

They look like general purpose registers, but there are a number of instructions which (unexpectedly?) use one of them—but which one?—implicitly.

update: added safer method

preferred method:

1. check out the previous (unchanged) state of your file; notice the double dash

   git checkout HEAD^ -- /path/to/file
   

2. commit it:

   git commit -am "revert changes on this file, not finished with it yet"
   

3. push it, no force needed:

   git push
   

4. get back to your unfinished work, again do (3 times arrow up):

   git checkout HEAD^ -- /path/to/file
   

effectively 'uncommitting':

To modify the last commit of the repository HEAD, obfuscating your accidentally pushed work, while potentially running into a conflict with your colleague who may have pulled it already, and who will grow grey hair and lose lots of time trying to reconcile his local branch head with the central one:

To remove file change from last commit:

1. to revert the file to the state before the last commit, do:

   git checkout HEAD^ /path/to/file
   

2. to update the last commit with the reverted file, do:

   git commit --amend
   

3. to push the updated commit to the repo, do:

   git push -f
   

Really, consider using the preferred method mentioned before.

You would call myBigDecimal.intValueExact() (or just intValue()) and it will even throw an exception if you would lose information. That returns an int but autoboxing takes care of that.

The Transact-SQL control-of-flow language keywords are:

BEGIN...END
BREAK
CONTINUE
GOTO label
IF...ELSE
RETURN
THROW
TRY...CATCH
WAITFOR
WHILE

If you want to have control over where they are placed separate from source code order:

Demo: http://jsfiddle.net/NmL2W/

<div id="NW"></div>
<div id="NE"></div>
<div id="SE"></div>?
<div id="SW"></div>

html, body { height:100%; margin:0; padding:0 }
div { position:fixed; width:50%; height:50% }
#NW { top:0;   left:0;   background:orange  }
#NE { top:0;   left:50%; background:blue    }
#SW { top:50%; left:0;   background:green   }
#SE { top:50%; left:50%; background:red     }    ?

Note: if you want padding on your regions, you'll need to set the box-sizing to border-box:

div {
  /* ... */
  padding:1em;
  box-sizing:border-box;
  -moz-box-sizing:border-box;
  -webkit-box-sizing:border-box;
}

…otherwise your "50%" width and height become "50% + 2em", which will lead to visual overlaps.

Using keyword arguments is the same thing as normal arguments except order doesn't matter. For example the two functions calls below are the same:

def foo(bar, baz):
    pass

foo(1, 2)
foo(baz=2, bar=1)

Try this:

    String sMillis = "10997195233";
    double dMillis = 0;

    int days = 0;
    int hours = 0;
    int minutes = 0;
    int seconds = 0;
    int millis = 0;

    String sTime;

    try {
        dMillis = Double.parseDouble(sMillis);
    } catch (Exception e) {
        System.out.println(e.getMessage());
    }


    seconds = (int)(dMillis / 1000) % 60;
    millis = (int)(dMillis % 1000);

    if (seconds > 0) {
        minutes = (int)(dMillis / 1000 / 60) % 60;
        if (minutes > 0) {
            hours = (int)(dMillis / 1000 / 60 / 60) % 24;
            if (hours > 0) {
                days = (int)(dMillis / 1000 / 60 / 60 / 24);
                if (days > 0) {
                    sTime = days + " days " + hours + " hours " + minutes + " min " + seconds + " sec " + millis + " millisec";
                } else {
                    sTime = hours + " hours " + minutes + " min " + seconds + " sec " + millis + " millisec";
                }
            } else {
                sTime = minutes + " min " + seconds + " sec " + millis + " millisec";
            }
        } else {
            sTime = seconds + " sec " + millis + " millisec";
        }
    } else {

    }

    System.out.println("time: " + sTime);

There's no guarantee that the content length you're provided is actually correct. Try something akin to the following:

ByteArrayOutputStream baos = new ByteArrayOutputStream();
InputStream is = null;
try {
  is = url.openStream ();
  byte[] byteChunk = new byte[4096]; // Or whatever size you want to read in at a time.
  int n;

  while ( (n = is.read(byteChunk)) > 0 ) {
    baos.write(byteChunk, 0, n);
  }
}
catch (IOException e) {
  System.err.printf ("Failed while reading bytes from %s: %s", url.toExternalForm(), e.getMessage());
  e.printStackTrace ();
  // Perform any other exception handling that's appropriate.
}
finally {
  if (is != null) { is.close(); }
}

You'll then have the image data in baos, from which you can get a byte array by calling baos.toByteArray().

This code is untested (I just wrote it in the answer box), but it's a reasonably close approximation to what I think you're after.

As detailed by this answer on this page, a status code of 0 means the request failed for some reason, and a javascript library interpreted the fail as a status code of 0.

To test this you can do either of the following:

1) Use this chrome extension, Requestly to redirect your url from the https version of your url to the http version, as this will cause a mixed content security error, and ultimately generate a status code of 0. The advantage of this approach is that you don't have to change your app at all, and you can simply "rewrite" your url using this extension.

2) Change the code of your app to optionally make your endpoint redirect to the http version of your url instead of the https version (or vice versa). If you do this, the request will fail with status code 0.

Leaving a reply (and an answer to the question title), For the future googlers...

You can use .length to get the length of a string.

var x = 'Mozilla'; var empty = '';

console.log('Mozilla is ' + x.length + ' code units long');

/*"Mozilla is 7 code units long" */

console.log('The empty string has a length of ' + empty.length);

/*"The empty string has a length of 0" */

If you intend to get the length of a textarea say id="txtarea" then you can use the following code.

txtarea = document.getElementById('txtarea');
console.log(txtarea.value.length);

You should be able to get away with using this with BMP Unicode symbols. If you want to support "non BMP Symbols" like (), then its an edge case, and you need to find some work around.

Some sample code for animating an expand/collapse action using a table view section header is provided by Apple here: Table View Animations and Gestures

The key to this approach is to implement - (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section and return a custom UIView which includes a button (typically the same size as the header view itself). By subclassing UIView and using that for the header view (as this sample does), you can easily store additional data such as the section number.

pandas.isnull() (also pd.isna(), in newer versions) checks for missing values in both numeric and string/object arrays. From the documentation, it checks for:

NaN in numeric arrays, None/NaN in object arrays

Quick example:

import pandas as pd
import numpy as np
s = pd.Series(['apple', np.nan, 'banana'])
pd.isnull(s)
Out[9]: 
0    False
1     True
2    False
dtype: bool

The idea of using numpy.nan to represent missing values is something that pandas introduced, which is why pandas has the tools to deal with it.

Datetimes too (if you use pd.NaT you won't need to specify the dtype)

In [24]: s = Series([Timestamp('20130101'),np.nan,Timestamp('20130102 9:30')],dtype='M8[ns]')

In [25]: s
Out[25]: 
0   2013-01-01 00:00:00
1                   NaT
2   2013-01-02 09:30:00
dtype: datetime64[ns]``

In [26]: pd.isnull(s)
Out[26]: 
0    False
1     True
2    False
dtype: bool

Firstly run this query

SHOW VARIABLES LIKE '%char%';

You have character_set_server='latin1'

If so,go into your config file,my.cnf and add or uncomment these lines:

character-set-server = utf8
collation-server = utf8_unicode_ci

Restart the server. Yes late to the party,just encountered the same issue.

If you interested in showing the Latitude and Longitude from the current direction , you can use this :

Directions are always given from the users current location.

The following query will help you perform that . You can pass the destination latitude and longitude here:

google.navigation:q=latitude,longitude

Use above as:

Uri gmmIntentUri = Uri.parse("google.navigation:q=latitude,longitude");
Intent mapIntent = new Intent(Intent.ACTION_VIEW, gmmIntentUri);
mapIntent.setPackage("com.google.android.apps.maps");
startActivity(mapIntent);

Or if you want to show via location , use:

google.navigation:q=a+street+address

More Info here: Google Maps Intents for Android

You have to specify that test1 is global:

test1 = 0
def testFunc():
    global test1
    test1 += 1
testFunc()

if you decide to use http://compass-style.org/, a sass-based css framework, it provides very useful darken() and lighten() sass functions to dynamically generate css. it's very clean:

@import compass/utilities

$link_color: #bb8f8f
a
  color: $link_color
a:visited
  color: $link_color
a:hover
  color: darken($link_color,10)

generates

a {
  color: #bb8f8f;
}

a:visited {
  color: #bb8f8f;
}

a:hover {
  color: #a86f6f;
}

Note however:

If you issue SET TRANSACTION ISOLATION LEVEL in a stored procedure or trigger, when the object returns control the isolation level is reset to the level in effect when the object was invoked. For example, if you set REPEATABLE READ in a batch, and the batch then calls a stored procedure that sets the isolation level to SERIALIZABLE, the isolation level setting reverts to REPEATABLE READ when the stored procedure returns control to the batch.

Sadly, they want us to use a tag to let their browser know what to do. Look at this documentation, it tell us to use:

<meta http-equiv="X-UA-Compatible" content="IE=edge" >

and it should do.

My solution was to completely remove the block in local.xml and create it with the blocks I needed, so, for example

<customer_account>
        <reference name="left">
            <action method="unsetChild">
                <name>customer_account_navigation</name>
            </action>
            <block type="customer/account_navigation" name="customer_account_navigation" before="-" template="customer/account/navigation.phtml">
                <action method="addLink" translate="label" module="customer">
                    <name>account</name>
                    <path>customer/account/</path>
                    <label>Account Dashboard</label>
                </action>
                <action method="addLink" translate="label" module="customer">
                    <name>account_edit</name>
                    <path>customer/account/edit/</path>
                    <label>Account Information</label>
                </action>
        </block>
    </reference>
</customer_account>

You may run:

git log <SHA1>..HEAD --ancestry-path --merges

From comment of last commit in the output you may find original branch name

Example:

       c---e---g--- feature
      /         \
-a---b---d---f---h---j--- master

git log e..master --ancestry-path --merges

commit h
Merge: g f

    Merge branch 'feature' into master

In Short (!): After you have declare a variable and that you are certain the variable is holding a value.

let assumedString: String! = "Some message..."
let implicitString: String = assumedString

else you would have to do this on every after passing value...

let possibleString: String? = "An optional string."
let forcedString: String = possibleString! // requires an exclamation mark

View view =(View) getActivity().findViewById(controlId);
Spinner spinner = (Spinner)view.findViewById(R.id.spinner1);
String valToSet = spinner.getSelectedItem().toString();

No, it is like I want to run Form_Load of Form A,if it is possible

-- Varun Mahajan

The usual way to do this is to put the relevant code in a procedure that can be called by both forms. It is best put the code in a standard module, but you could have it on Form a:

Form B:

Sub RunFormALoad()
   Forms!FormA.ToDoOnLoad
End Sub

Form A:

Public Sub Form_Load()
    ToDoOnLoad
End Sub    

Sub ToDoOnLoad()
    txtText = "Hi"
End Sub

This is a later answer that works for me, if it may be of use to anyone in the future. I wanted a simple border around all four sides of the grid and I achieved it like so...

<DataGrid x:Name="dgDisplay" Margin="5" BorderBrush="#1266a7" BorderThickness="1"...

first select the table you you would like to make the relation with >> then go to operation , for each table there is difference operation setting, >> inside operation "storage engine" choose innoDB option

innoDB will allow you to view the "relation view" which will help you make the foreign key

This is my solution to scroll to the top on a button click.

$(".btn").click(function () {
if ($(this).text() == "Show options") {
$(".tabs").animate(
  {
    scrollTop: $(window).scrollTop(0)
  },
  "slow"
 );
 }
});

To add to craig_h's comment above (I currently don't have enough rep to add this as a comment to his answer, sorry), if your primary key is not an integer, you'll also want to tell your model what data type it is, by setting keyType at the top of the model definition.

public $keyType = 'string'

Eloquent understands any of the types defined in the castAttribute() function, which as of Laravel 5.4 are: int, float, string, bool, object, array, collection, date and timestamp.

This will ensure that your primary key is correctly cast into the equivalent PHP data type.

To delete content without a folder you can use the following:

Remove-Item "foldertodelete\*" -Force -Recurse

Sometimes you get a case where some of the requests made with axios are pointed to endpoints that do not accept authorization headers. Thus, alternative way to set authorization header only on allowed domain is as in the example below. Place the following function in any file that gets executed each time React application runs such as in routes file.

export default () => {
    axios.interceptors.request.use(function (requestConfig) {
        if (requestConfig.url.indexOf(<ALLOWED_DOMAIN>) > -1) {
            const token = localStorage.token;
            requestConfig.headers['Authorization'] = `Bearer ${token}`;
        }

        return requestConfig;
    }, function (error) {
        return Promise.reject(error);
    });

}

Very easiest way to call one activity to another is

startActivity( new Intent( getApplicationContext(), YourActivity.class ) );

It depends on the context.

• "undefined" means this value does not exist. typeof returns "undefined"

• "null" means this value exists with an empty value. When you use typeof to test for "null", you will see that it's an object. Other case when you serialize "null" value to backend server like asp.net mvc, the server will receive "null", but when you serialize "undefined", the server is unlikely to receive a value.

Git tags are just pointers to the commit. So you use them the same way as you do HEAD, branch names or commit sha hashes. You can use tags with any git command that accepts commit/revision arguments. You can try it with git rev-parse tagname to display the commit it points to.

In your case you have at least these two alternatives:

1. Reset the current branch to specific tag:

   git reset --hard tagname
   

2. Generate revert commit on top to get you to the state of the tag:

   git revert tag
   

This might introduce some conflicts if you have merge commits though.

According to the article Chris Corio: Teach Your Apps To Play Nicely With Windows Vista User Account Control, MSDN Magazine, Jan. 2007, only ShellExecute checks the embedded manifest and prompts the user for elevation if needed, while CreateProcess and other APIs don't. Hope it helps.

One thing that the above solutions don't take into account is if you have an array of inputs but only one value was supplied.

For instance, if the back end expects an array of People, but in this particular case, you are just dealing with a single person. Then doing:

<input type="hidden" name="People" value="Joe" />

Then with the previous solutions, it would just map to something like:

{
    "People" : "Joe"
}

But it should really map to

{
    "People" : [ "Joe" ]
}

To fix that, the input should look like:

<input type="hidden" name="People[]" value="Joe" />

And you would use the following function (based off of other solutions, but extended a bit)

$.fn.serializeObject = function() {
var o = {};
var a = this.serializeArray();
$.each(a, function() {
    if (this.name.substr(-2) == "[]"){
        this.name = this.name.substr(0, this.name.length - 2);
        o[this.name] = [];
    }

    if (o[this.name]) {
        if (!o[this.name].push) {
            o[this.name] = [o[this.name]];
        }
        o[this.name].push(this.value || '');
    } else {
        o[this.name] = this.value || '';
    }
});
return o;
};

The following works as expected:

SELECT  Diff = CASE DATEDIFF(HOUR, StartTime, EndTime)
                    WHEN 0 THEN CAST(DATEDIFF(MINUTE, StartTime, EndTime) AS VARCHAR(10))
                    ELSE CAST(60 - DATEPART(MINUTE, StartTime) AS VARCHAR(10)) +
                        REPLICATE(',60', DATEDIFF(HOUR, StartTime, EndTime) - 1) + 
                        + ',' + CAST(DATEPART(MINUTE, EndTime) AS VARCHAR(10))
                END
FROM    (VALUES 
            (CAST('11:15' AS TIME), CAST('13:15' AS TIME)),
            (CAST('10:45' AS TIME), CAST('18:59' AS TIME)),
            (CAST('10:45' AS TIME), CAST('11:59' AS TIME))
        ) t (StartTime, EndTime);

To get 24 columns, you could use 24 case expressions, something like:

SELECT  [0] = CASE WHEN DATEDIFF(HOUR, StartTime, EndTime) = 0
                        THEN DATEDIFF(MINUTE, StartTime, EndTime)
                    ELSE 60 - DATEPART(MINUTE, StartTime)
                END,
        [1] = CASE WHEN DATEDIFF(HOUR, StartTime, EndTime) = 1 
                        THEN DATEPART(MINUTE, EndTime)
                    WHEN DATEDIFF(HOUR, StartTime, EndTime) > 1 THEN 60
                END,
        [2] = CASE WHEN DATEDIFF(HOUR, StartTime, EndTime) = 2
                        THEN DATEPART(MINUTE, EndTime)
                    WHEN DATEDIFF(HOUR, StartTime, EndTime) > 2 THEN 60
                END -- ETC
FROM    (VALUES 
            (CAST('11:15' AS TIME), CAST('13:15' AS TIME)),
            (CAST('10:45' AS TIME), CAST('18:59' AS TIME)),
            (CAST('10:45' AS TIME), CAST('11:59' AS TIME))
        ) t (StartTime, EndTime);

The following also works, and may end up shorter than repeating the same case expression over and over:

WITH Numbers (Number) AS
(   SELECT  ROW_NUMBER() OVER(ORDER BY t1.N) - 1
    FROM    (VALUES (1), (1), (1), (1), (1), (1)) AS t1 (N)
            CROSS JOIN (VALUES (1), (1), (1), (1)) AS t2 (N)
), YourData AS
(   SELECT  StartTime, EndTime
    FROM    (VALUES 
                (CAST('11:15' AS TIME), CAST('13:15' AS TIME)),
                (CAST('09:45' AS TIME), CAST('18:59' AS TIME)),
                (CAST('10:45' AS TIME), CAST('11:59' AS TIME))
            ) AS t (StartTime, EndTime)
), PivotData AS
(   SELECT  t.StartTime,
            t.EndTime,
            n.Number,
            MinuteDiff = CASE WHEN n.Number = 0 AND DATEDIFF(HOUR, StartTime, EndTime) = 0 THEN DATEDIFF(MINUTE, StartTime, EndTime)
                                WHEN n.Number = 0 THEN 60 - DATEPART(MINUTE, StartTime)
                                WHEN DATEDIFF(HOUR, t.StartTime, t.EndTime) <= n.Number THEN DATEPART(MINUTE, EndTime)
                                ELSE 60
                            END
    FROM    YourData AS t
            INNER JOIN Numbers AS n
                ON n.Number <= DATEDIFF(HOUR, StartTime, EndTime)
)
SELECT  *
FROM    PivotData AS d
        PIVOT 
        (   MAX(MinuteDiff)
            FOR Number IN 
            (   [0], [1], [2], [3], [4], [5], 
                [6], [7], [8], [9], [10], [11],
                [12], [13], [14], [15], [16], [17], 
                [18], [19], [20], [21], [22], [23]
            ) 
        ) AS pvt;

It works by joining to a table of 24 numbers, so the case expression doesn't need to be repeated, then rolling these 24 numbers back up into columns using PIVOT

This problem is due to private key in the certificate in your profile not match that in your keychain. I resolve this by

1. delete all iPhone Developer certificate in keychain.
2. delete all certificate in apple account.
3. using xcode "Manage Certificates" to add certificate, sometime you still have certificate in your Mac, but I do not know where it is for now, and if added successfully, your apple account will display that certificate too, and then you can create your profile with that certificate and download ... goto 5
4. if you use "Manage Certificates" can't add certificate, you can create a new certificate, and do remain steps.
5. finish.

Disclaimer: this answer does not endorse the use of the Date class (in fact it’s long outdated and poorly designed, so I’d rather discourage it completely). I try to answer a regularly recurring question about date and time objects with a format. For this purpose I am using the Date class as example. Other classes are treated at the end.

You don’t want to

You don’t want a Date with a specific format. Good practice in all but the simplest throw-away programs is to keep your user interface apart from your model and your business logic. The value of the Date object belongs in your model, so keep your Date there and never let the user see it directly. When you adhere to this, it will never matter which format the Date has got. Whenever the user should see the date, format it into a String and show the string to the user. Similarly if you need a specific format for persistence or exchange with another system, format the Date into a string for that purpose. If the user needs to enter a date and/or time, either accept a string or use a date picker or time picker.

Special case: storing into an SQL database. It may appear that your database requires a specific format. Not so. Use yourPreparedStatement.setObject(yourParamIndex, yourDateOrTimeObject) where yourDateOrTimeObject is a LocalDate, Instant, LocalDateTime or an instance of an appropriate date-time class from java.time. And again don’t worry about the format of that object. Search for more details.

You cannot

A Date hasn’t got, as in cannot have a format. It’s a point in time, nothing more, nothing less. A container of a value. In your code sdf1.parse converts your string into a Date object, that is, into a point in time. It doesn’t keep the string nor the format that was in the string.

To finish the story, let’s look at the next line from your code too:

    System.out.println("Current date in Date Format: "+date);

In order to perform the string concatenation required by the + sign Java needs to convert your Date into a String first. It does this by calling the toString method of your Date object. Date.toString always produces a string like Thu Jan 05 21:10:17 IST 2012. There is no way you could change that (except in a subclass of Date, but you don’t want that). Then the generated string is concatenated with the string literal to produce the string printed by System.out.println.

In short “format” applies only to the string representations of dates, not to the dates themselves.

Isn’t it strange that a Date hasn’t got a format?

I think what I’ve written is quite as we should expect. It’s similar to other types. Think of an int. The same int may be formatted into strings like 53,551, 53.551 (with a dot as thousands separator), 00053551, +53 551 or even 0x0000_D12F. All of this formatting produces strings, while the int just stays the same and doesn’t change its format. With a Date object it’s exactly the same: you can format it into many different strings, but the Date itself always stays the same.

Can I then have a LocalDate, a ZonedDateTime, a Calendar, a GregorianCalendar, an XMLGregorianCalendar, a java.sql.Date, Time or Timestamp in the format of my choice?

No, you cannot, and for the same reasons as above. None of the mentioned classes, in fact no date or time class I have ever met, can have a format. You can have your desired format only in a String outside your date-time object.

1. Omit the viewport <meta> mentioned in the CSS docs
2. Override the width on the .container for each grid tier with a single width, for example width: 970px !important; Be sure that this comes after the default Bootstrap CSS. You can optionally avoid the !important with media queries or some selector-fu.
3. If using navbars, remove all navbar collapsing and expanding behavior.
4. For grid layouts, use .col-xs-* classes in addition to, or in place of, the medium/large ones. Don't worry, the extra-small device grid scales to all resolutions.

You can append the text to $0 in awk if it matches the condition:

awk '/^all:/ {$0=$0" anotherthing"} 1' file

Explanation

• /patt/ {...} if the line matches the pattern given by patt, then perform the actions described within {}.
• In this case: /^all:/ {$0=$0" anotherthing"} if the line starts (represented by ^) with all:, then append anotherthing to the line.
• 1 as a true condition, triggers the default action of awk: print the current line (print $0). This will happen always, so it will either print the original line or the modified one.

Test

For your given input it returns:

somestuff...
all: thing otherthing anotherthing
some other stuff

Note you could also provide the text to append in a variable:

$ awk -v mytext=" EXTRA TEXT" '/^all:/ {$0=$0mytext} 1' file
somestuff...
all: thing otherthing EXTRA TEXT
some other stuff

In the same idea of Nick Riggs but I create a constructor, and a push a new object in the array by using it. It avoid the repetition of the keys of the class:

var arr = [];
var columnDefs = function(key, sortable, resizeable){
    this.key = key; 
    this.sortable = sortable; 
    this.resizeable = resizeable;
    };

for (var i = 0; i < len; i++) {
    arr.push((new columnDefs(oFullResponse.results[i].label,true,true)));
}

If you use nano with a language like python (as in your example) it's also a good idea to convert tabs to spaces.

Edit your ~/.nanorc file (or create it) and add:

set tabsize 4
set tabstospaces

If you already got a file with tabs and want to convert them to spaces i recommend the expandcommand (shell):

expand -4 input.py > output.py

The loop in your code is only an over-simplified example, right?

It would be better to create the PreparedStatement only once, and re-use it over and over again in the loop.

In situations where that is not possible (because it complicated the program flow too much), it is still beneficial to use a PreparedStatement, even if you use it only once, because the server-side of the work (parsing the SQL and caching the execution plan), will still be reduced.

To address the situation that you want to re-use the Java-side PreparedStatement, some JDBC drivers (such as Oracle) have a caching feature: If you create a PreparedStatement for the same SQL on the same connection, it will give you the same (cached) instance.

About multi-threading: I do not think JDBC connections can be shared across multiple threads (i.e. used concurrently by multiple threads) anyway. Every thread should get his own connection from the pool, use it, and return it to the pool again.

Or you could do it properly:

In your HtmlHelper Extension class:

public static MvcHtmlString FileFor<TModel, TProperty>(this HtmlHelper<TModel> helper, Expression<Func<TModel, TProperty>> expression)
    {
        return helper.FileFor(expression, null);
    }

public static MvcHtmlString FileFor<TModel, TProperty>(this HtmlHelper<TModel> helper, Expression<Func<TModel, TProperty>> expression, object htmlAttributes)
    {
        var builder = new TagBuilder("input");

        var id = helper.ViewContext.ViewData.TemplateInfo.GetFullHtmlFieldName(ExpressionHelper.GetExpressionText(expression));
        builder.GenerateId(id);
        builder.MergeAttribute("name", id);
        builder.MergeAttribute("type", "file");

        builder.MergeAttributes(new RouteValueDictionary(htmlAttributes));

        // Render tag
        return MvcHtmlString.Create(builder.ToString(TagRenderMode.SelfClosing));
    }

This line:

var id = helper.ViewContext.ViewData.TemplateInfo.GetFullHtmlFieldName(ExpressionHelper.GetExpressionText(expression));

Generates an id unique to the model, you know in lists and stuff. model[0].Name etc.

Create the correct property in the model:

public HttpPostedFileBase NewFile { get; set; }

Then you need to make sure your form will send files:

@using (Html.BeginForm("Action", "Controller", FormMethod.Post, new { enctype = "multipart/form-data" }))

Then here's your helper:

@Html.FileFor(x => x.NewFile)

This is how I solved the issue on my computer:

1. Open Visual Studio Code
2. Go to File -> Preferences -> Settings
3. Under User tab, expand Extensions and select Git

4. Find Autofetch on the right pane and uncheck it

If you want absolute urls, you have the third parameter.

$product_url = $this->generateUrl('product_detail', 
    array(
        'slug' => 'slug'
    ),
    UrlGeneratorInterface::ABSOLUTE_URL
);

Remember to include UrlGeneratorInterface.

use Symfony\Component\Routing\Generator\UrlGeneratorInterface;

There is a which.py script in a standard Python distribution (e.g. on Windows '\PythonXX\Tools\Scripts\which.py').

EDIT: which.py depends on ls therefore it is not cross-platform.

I was able to get around this loading the headers before the HTML with php, and it worked very well.

<?php 
header( 'X-UA-Compatible: IE=edge,chrome=1' );
header( 'content: width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no' );
include('ix.html');
?> 

ix.html is the content I wanted to load after sending the headers.

No:

You can verify this in Chrome and Firefox by checking the list of computed styles. Other properties that have shorthand methods (like border-radius) have their variations defined in the spec.

As with most missing "long-hand" CSS properties, CSS variables can solve this problem:

#el {
    --box-shadow-color: palegoldenrod;
    box-shadow: 1px 2px 3px var(--box-shadow-color);
}

#el:hover {
    --box-shadow-color: goldenrod;
}

1. Settings
2. General
3. General Project Settings

Here, we can do this way as well:

//category [@name='category name']/author[contains(text(),'authorname')]

OR

//category [@name='category name']//author[contains(text(),'authorname')]

almost there, just change outerWidth: 100%; to width: auto; (outerWidth is not a CSS property)

alternatively, apply the following styles to bar:

width: auto;
display: block;

As Damian noted here Command line subversion client for Windows Vista 64bits TortoiseSVN has command line tools that are unchecked by default during installation.

I'm very happy with kdesvn - integrates very well with konqueror, much like trortousesvn with windows explorer, and supports most of the functionality of tortoisesvn.

Of course, you'll benefit from this integration, if you use kubunto, and not ubuntu.

SyntaxError: Unexpected token < in JSON at position 0

You are getting an html file instead of json.

Html files begin with <!DOCTYPE html>.

I "achieved" this error by forgetting the https:// in my fetch method:

fetch(`/api.github.com/users/${login}`)
    .then(response => response.json())
    .then(setData);

I verified my hunch:

I logged the response as text instead of JSON.

fetch(`/api.github.com/users/${login}`)
    .then(response => response.text())
    .then(text => console.log(text))
    .then(setData);

Yep, an html file.

Solution:

I fixed the error by adding back the https:// in my fetch method.

fetch(`https://api.github.com/users/${login}`)
    .then(response => response.json())
    .then(setData)
    .catch(error => (console.log(error)));

If you are using Bootstrap CSS...

I have created a simple re-usable tree control (directive) for AngularJS based on a Bootstrap "nav" list. I added extra indentation, icons, and animation. HTML attributes are used for configuration.

It does not use recursion.

I called it angular-bootstrap-nav-tree ( catchy name, don't you think? )

There is an example here, and the source is here.

This tutorial gives a simple, yet elegant, solution, which i transcribe:

#include <sstream>
#include <string>
#include <stdexcept>

class BadConversion : public std::runtime_error {
public:
  BadConversion(std::string const& s)
    : std::runtime_error(s)
    { }
};

inline std::string stringify(double x)
{
  std::ostringstream o;
  if (!(o << x))
    throw BadConversion("stringify(double)");
  return o.str();
}
...
std::string my_val = stringify(val);

Angular5 and 6:

angular 5 and 6 recommended way is to use @HostBindings and @HostListeners instead of the host property

remove host and add @HostListener

 @HostListener('ngModelChange', ['$event'])
  onModelChange(event) {
    this.onInputChange(event, false);
  }

  @HostListener('keydown.backspace', ['$event'])
  keydownBackspace(event) {
    this.onInputChange(event.target.value, true);
  }

One way you could do it is using a directive that injects NgControl and manipulates the value

(for details see inline comments)

@Directive({
  selector: '[ngModel][phone]',
  host: {
    '(ngModelChange)': 'onInputChange($event)',
    '(keydown.backspace)': 'onInputChange($event.target.value, true)'
  }
})
export class PhoneMask {
  constructor(public model: NgControl) {}

  onInputChange(event, backspace) {
    // remove all mask characters (keep only numeric)
    var newVal = event.replace(/\D/g, '');
    // special handling of backspace necessary otherwise
    // deleting of non-numeric characters is not recognized
    // this laves room for improvement for example if you delete in the 
    // middle of the string
    if (backspace) {
      newVal = newVal.substring(0, newVal.length - 1);
    } 

    // don't show braces for empty value
    if (newVal.length == 0) {
      newVal = '';
    } 
    // don't show braces for empty groups at the end
    else if (newVal.length <= 3) {
      newVal = newVal.replace(/^(\d{0,3})/, '($1)');
    } else if (newVal.length <= 6) {
      newVal = newVal.replace(/^(\d{0,3})(\d{0,3})/, '($1) ($2)');
    } else {
      newVal = newVal.replace(/^(\d{0,3})(\d{0,3})(.*)/, '($1) ($2)-$3');
    }
    // set the new value
    this.model.valueAccessor.writeValue(newVal);       
  }
}

@Component({
  selector: 'my-app',
  providers: [],
  template: `
  <form [ngFormModel]="form">
    <input type="text" phone [(ngModel)]="data" ngControl="phone"> 
  </form>
  `,
  directives: [PhoneMask]
})
export class App {
  constructor(fb: FormBuilder) {
    this.form = fb.group({
      phone: ['']
    })
  }
}

Plunker example <= RC.5

You might looking for the placeholder attribute which will display a grey text in the input field while empty.

From Mozilla Developer Network:

A hint to the user of what can be entered in the control . The placeholder text must not contain carriage returns or line-feeds. This attribute applies when the value of the type attribute is text, search, tel, url or email; otherwise it is ignored.

However as it's a fairly 'new' tag (from the HTML5 specification afaik) you might want to to browser testing to make sure your target audience is fine with this solution.
(If not tell tell them to upgrade browser 'cause this tag works like a charm ;o) )

And finally a mini-fiddle to see it directly in action: http://jsfiddle.net/LnU9t/

Edit: Here is a plain jQuery solution which will also clear the input field if an escape keystroke is detected: http://jsfiddle.net/3GLwE/
