I didn't see this mentioned yet, but beans have a built-in method called getProperties().

So, to use it:

// What bean do we want to get?
$type = 'book';
$id = 13;

// Load the bean
$post = R::load($type,$id);

// Get the properties
$props = $post->getProperties();

// Print the JSON-encoded value
print json_encode($props);

This outputs:

{
    "id": "13",
    "title": "Oliver Twist",
    "author": "Charles Dickens"
}

Now take it a step further. If we have an array of beans...

// An array of beans (just an example)
$series = array($post,$post,$post);

...then we could do the following:

• Loop through the array with a foreach loop.

• Replace each element (a bean) with an array of the bean's properties.

So this...

foreach ($series as &$val) {
  $val = $val->getProperties();
}

print json_encode($series);

...outputs this:

[
    {
        "id": "13",
        "title": "Oliver Twist",
        "author": "Charles Dickens"
    },
    {
        "id": "13",
        "title": "Oliver Twist",
        "author": "Charles Dickens"
    },
    {
        "id": "13",
        "title": "Oliver Twist",
        "author": "Charles Dickens"
    }
]

Hope this helps!

Here is one combining noquote and paste:

noquote(paste("Argument is of length zero",sQuote("!"),"and",dQuote("double")))


#[1] Argument is of length zero ‘!’ and “double”

Arithmetic operations involving float results in float.

int + float = float
int * float = float
float * int = float
int / float = float
float / int = float
int / int = int

For more detail answer. Look at what the section §5/9 from the C++ Standard says

Many binary operators that expect operands of arithmetic or enumeration type cause conversions and yield result types in a similar way. The purpose is to yield a common type, which is also the type of the result.

This pattern is called the usual arithmetic conversions, which are defined as follows:

— If either operand is of type long double, the other shall be converted to long double.

— Otherwise, if either operand is double, the other shall be converted to double.

— Otherwise, if either operand is float, the other shall be converted to float.

— Otherwise, the integral promotions (4.5) shall be performed on both operands.54)

— Then, if either operand is unsigned long the other shall be converted to unsigned long.

— Otherwise, if one operand is a long int and the other unsigned int, then if a long int can represent all the values of an unsigned int, the unsigned int shall be converted to a long int; otherwise both operands shall be converted to unsigned long int.

— Otherwise, if either operand is long, the other shall be converted to long.

— Otherwise, if either operand is unsigned, the other shall be converted to unsigned.

[Note: otherwise, the only remaining case is that both operands are int ]

Frameworks usually use bracket names in forms, like:

<input name=user[first_name] />

They can be accessed by:

// in JS:
this.querySelectorAll('[name="user[first_name]"]')

// in jQuery:
$('[name="user[first_name]"]')

// or by mask with escaped quotes:
this.querySelectorAll("[name*=\"[first_name]\"]")

You have to create a password file: see http://www.postgresql.org/docs/9.0/interactive/libpq-pgpass.html for more info.

Try the following:

List<string> test1 = new List<string> { "@bob.com", "@tom.com" };
List<string> test2 = new List<string> { "[email protected]", "[email protected]" };
var output = from goodEmails in test2
            where !(from email in test2
                from domain in test1
                where email.EndsWith(domain)
                select email).Contains(goodEmails)
            select goodEmails;

This works with the test set provided (and looks correct).

I suppose that 255 in 227./255 is perceived as an integer and divide is always return 0

In a Colab notebook you can do:

from IPython.display import Audio
Audio(waveform, Rate=16000)

ByteArrayInputStream also does the trick:

InputStream is = new ByteArrayInputStream( myString.getBytes( charset ) );

Then convert to reader:

InputStreamReader reader = new InputStreamReader(is);

Originally from this blog post. We can achieve if else by using below code

<xsl:choose>
    <xsl:when test="something to test">

    </xsl:when>
    <xsl:otherwise>

</xsl:choose>

So here is what I did

First set delegate in viewDidLoad:

self.navigationController.interactivePopGestureRecognizer.delegate = self;

And then disable gesture when pushing:

- (void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated {
    [super pushViewController:viewController animated:animated];
    self.interactivePopGestureRecognizer.enabled = NO;
}

And enable in viewDidDisappear:

self.navigationController.interactivePopGestureRecognizer.enabled = YES;

Also, add UINavigationControllerDelegate to your view controller.

IMHO answering this question with the use of ExpressJS is to give a superficial answer. I am going to answer the best I can with out the use of any frameworks or modules. The reason this question is often answerd with the use of a framework is becuase it takes away the requirment of understanding 'Hypertext-Transfer-Protocall'.

1. The first thing that should be pointed out is that this is more a problem surrounding "Hypertext-Transfer-Protocol" than it is Javascript. When request are made the url is sent, aswell as the content-type that is expected.
2. The second thing to understand is where request come from. Iitialy a person will request a HTML document, but depending on what is written inside the document, the document itsself might make requests of the server, such as: Images, stylesheets and more. This question refers to CSS so we will keep our focus there. In a tag that links a CSS file to an HTML file there are 3 properties. rel="stylesheet" type="text/css" and href="http://localhost/..." for this example we are going to focus on type and href. Type sends a request to the server that lets the server know it is requesting 'text/css', and 'href' is telling it where the request is being made too.

so with that pointed out we now know what information is being sent to the server now we can now seperate css request from html request on our serverside using a bit of javascript.

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




    function onRequest(request, response){  
        if(request.headers.accept.split(',')[0] == 'text/css') {
             console.log('TRUE');

             fs.readFile('index.css', (err, data)=>{
                 response.writeHeader(200, {'Content-Type': 'text/css'});
                 response.write(data);
                 response.end();
             });  
        }

        else {
            console.log('FALSE');    

            fs.readFile('index.html', function(err, data){
                response.writeHead(200, {'Content_type': 'text/html'});
                response.write(data);
                response.end();
            });
        };
    };

    http.createServer(onRequest).listen(8888);
    console.log('[SERVER] - Started!');

Here is a quick sample of one way I might seperate request. Now remember this is a quick example that would typically be split accross severfiles, some of which would have functions as dependancys to others, but for the sack of 'all in a nutshell' this is the best I could do. I tested it and it worked. Remember that index.css and index.html can be swapped with any html/css files you want.

window.location = document.referrer;

With TypeScript, it is easy to find what you want with the right type.

import { AxiosResponse, AxiosError } from 'axios'

axios.get('foo.com')
  .then(response: AxiosResponse => {
    // Handle response
  })
  .catch((reason: AxiosError) => {
    if (reason.response!.status === 400) {
      // Handle 400
    } else {
      // Handle else
    }
    console.log(reason.message)
  })

In my case, I was getting this error because I had an input named x and I was creating (without realizing it) a local variable called x. I thought I was trying to access an element of the input x (which was an array), while I was actually trying to access an element of the local variable x (which was a scalar).

Just an update for Laravel 5:

In Laravel 4.2:

use Illuminate\Database\Eloquent\SoftDeletingTrait;    
class Post extends Eloquent {

    use SoftDeletingTrait;

    protected $dates = ['deleted_at'];

}

becomes in Laravel 5:

use Illuminate\Database\Eloquent\SoftDeletes;

class User extends Model {

    use SoftDeletes;
    protected $dates = ['deleted_at'];

Yes, it is extremely useful in browsers that support it, but the "limiting" is as a convenience to users (so they are not overwhelmed with irrelevant files) rather than as a way to prevent them from uploading things you don't want them uploading.

It is supported in

• Chrome 16 +
• Safari 6 +
• Firefox 9 +
• IE 10 +
• Opera 11 +

Truth values can be described using a Boolean algebra. The article also contains tables for and and or. This should help you to get started or to get even more confused.

In my case I had curly braces where it should have been parentheses.

const Button = () => {
    <button>Hello world</button>
}

Where it should have been:

const Button = () => (
    <button>Hello world</button>
)

The reason for this, as explained in the MDN Docs is that an arrow function wrapped by () will return the value it wraps, so if I wanted to use curly braces I had to add the return keyword, like so:

const Button = () => {
    return <button>Hello world</button>
}

The struct module mimics C structures. It takes more CPU cycles for a processor to read a 16-bit word on an odd address or a 32-bit dword on an address not divisible by 4, so structures add "pad bytes" to make structure members fall on natural boundaries. Consider:

struct {                   11
    char a;      012345678901
    short b;     ------------
    char c;      axbbcxxxdddd
    int d;
};

This structure will occupy 12 bytes of memory (x being pad bytes).

Python works similarly (see the struct documentation):

>>> import struct
>>> struct.pack('BHBL',1,2,3,4)
'\x01\x00\x02\x00\x03\x00\x00\x00\x04\x00\x00\x00'
>>> struct.calcsize('BHBL')
12

Compilers usually have a way of eliminating padding. In Python, any of =<>! will eliminate padding:

>>> struct.calcsize('=BHBL')
8
>>> struct.pack('=BHBL',1,2,3,4)
'\x01\x02\x00\x03\x04\x00\x00\x00'

Beware of letting struct handle padding. In C, these structures:

struct A {       struct B {
    short a;         int a;
    char b;          char b;
};               };

are typically 4 and 8 bytes, respectively. The padding occurs at the end of the structure in case the structures are used in an array. This keeps the 'a' members aligned on correct boundaries for structures later in the array. Python's struct module does not pad at the end:

>>> struct.pack('LB',1,2)
'\x01\x00\x00\x00\x02'
>>> struct.pack('LBLB',1,2,3,4)
'\x01\x00\x00\x00\x02\x00\x00\x00\x03\x00\x00\x00\x04'

In SQL, a comparison between a null value and any other value (including another null) using a comparison operator (eg =, !=, <, etc) will result in a null, which is considered as false for the purposes of a where clause (strictly speaking, it's "not true", rather than "false", but the effect is the same).

The reasoning is that a null means "unknown", so the result of any comparison to a null is also "unknown". So you'll get no hit on rows by coding where my_column = null.

SQL provides the special syntax for testing if a column is null, via is null and is not null, which is a special condition to test for a null (or not a null).

Here's some SQL showing a variety of conditions and and their effect as per above.

create table t (x int, y int);
insert into t values (null, null), (null, 1), (1, 1);

select 'x = null' as test , x, y from t where x = null
union all
select 'x != null', x, y from t where x != null
union all
select 'not (x = null)', x, y from t where not (x = null)
union all
select 'x = y', x, y from t where x = y
union all
select 'not (x = y)', x, y from t where not (x = y);

returns only 1 row (as expected):

TEST    X   Y
x = y   1   1

See this running on SQLFiddle

I just ran over this one and I found by accident that CLOBs can be used in a like query:

   UPDATE IMS_TEST 
   SET TEST_Category  = 'just testing'  
 WHERE TEST_SCRIPT    LIKE '%something%'
   AND ID             = '10000239' 

This worked also for CLOBs greater than 4K

The Performance won't be great but that was no problem in my case.

I actually found that calling fullScroll twice does the trick:

myScrollView.fullScroll(View.FOCUS_DOWN);

myScrollView.post(new Runnable() {
    @Override
    public void run() {
        myScrollView.fullScroll(View.FOCUS_DOWN);
    }
});

It may have something to do with the activation of the post() method right after performing the first (unsuccessful) scroll. I think this behavior occurs after any previous method call on myScrollView, so you can try replacing the first fullScroll() method by anything else that may be relevant to you.

Try:

names(newprice)[1] <- "premium"

Naïve datetime versus aware datetime

Default datetime objects are said to be "naïve": they keep time information without the time zone information. Think about naïve datetime as a relative number (ie: +4) without a clear origin (in fact your origin will be common throughout your system boundary).

In contrast, think about aware datetime as absolute numbers (ie: 8) with a common origin for the whole world.

Without timezone information you cannot convert the "naive" datetime towards any non-naive time representation (where does +4 targets if we don't know from where to start ?). This is why you can't have a datetime.datetime.toutctimestamp() method. (cf: http://bugs.python.org/issue1457227)

To check if your datetime dt is naïve, check dt.tzinfo, if None, then it's naïve:

datetime.now()        ## DANGER: returns naïve datetime pointing on local time
datetime(1970, 1, 1)  ## returns naïve datetime pointing on user given time

I have naïve datetimes, what can I do ?

You must make an assumption depending on your particular context: The question you must ask yourself is: was your datetime on UTC ? or was it local time ?

• If you were using UTC (you are out of trouble):

  import calendar
  
  def dt2ts(dt):
      """Converts a datetime object to UTC timestamp
  
      naive datetime will be considered UTC.
  
      """
  
      return calendar.timegm(dt.utctimetuple())
  

• If you were NOT using UTC, welcome to hell.

  You have to make your datetime non-naïve prior to using the former function, by giving them back their intended timezone.

  You'll need the name of the timezone and the information about if DST was in effect when producing the target naïve datetime (the last info about DST is required for cornercases):

  import pytz     ## pip install pytz
  
  mytz = pytz.timezone('Europe/Amsterdam')             ## Set your timezone
  
  dt = mytz.normalize(mytz.localize(dt, is_dst=True))  ## Set is_dst accordingly
  

  Consequences of not providing is_dst:

  Not using is_dst will generate incorrect time (and UTC timestamp) if target datetime was produced while a backward DST was put in place (for instance changing DST time by removing one hour).

  Providing incorrect is_dst will of course generate incorrect time (and UTC timestamp) only on DST overlap or holes. And, when providing also incorrect time, occuring in "holes" (time that never existed due to forward shifting DST), is_dst will give an interpretation of how to consider this bogus time, and this is the only case where .normalize(..) will actually do something here, as it'll then translate it as an actual valid time (changing the datetime AND the DST object if required). Note that .normalize() is not required for having a correct UTC timestamp at the end, but is probably recommended if you dislike the idea of having bogus times in your variables, especially if you re-use this variable elsewhere.

  and AVOID USING THE FOLLOWING: (cf: Datetime Timezone conversion using pytz)

  dt = dt.replace(tzinfo=timezone('Europe/Amsterdam'))  ## BAD !!
  

  Why? because .replace() replaces blindly the tzinfo without taking into account the target time and will choose a bad DST object. Whereas .localize() uses the target time and your is_dst hint to select the right DST object.

OLD incorrect answer (thanks @J.F.Sebastien for bringing this up):

Hopefully, it is quite easy to guess the timezone (your local origin) when you create your naive datetime object as it is related to the system configuration that you would hopefully NOT change between the naive datetime object creation and the moment when you want to get the UTC timestamp. This trick can be used to give an imperfect question.

By using time.mktime we can create an utc_mktime:

def utc_mktime(utc_tuple):
    """Returns number of seconds elapsed since epoch

    Note that no timezone are taken into consideration.

    utc tuple must be: (year, month, day, hour, minute, second)

    """

    if len(utc_tuple) == 6:
        utc_tuple += (0, 0, 0)
    return time.mktime(utc_tuple) - time.mktime((1970, 1, 1, 0, 0, 0, 0, 0, 0))

def datetime_to_timestamp(dt):
    """Converts a datetime object to UTC timestamp"""

    return int(utc_mktime(dt.timetuple()))

You must make sure that your datetime object is created on the same timezone than the one that has created your datetime.

This last solution is incorrect because it makes the assumption that the UTC offset from now is the same than the UTC offset from EPOCH. Which is not the case for a lot of timezones (in specific moment of the year for the Daylight Saving Time (DST) offsets).

I run into the same problem. Then I went into Run as -> Ant build...->jre. I found the jre used is separate JRE which is the default eclipse JRE(1.6). Then I went to the perferences ->installed JREs . And change the location of the default eclipse JRE to my jdk(1.7).

The problem is resolved.

The only way I've managed to do this is by using overflow: visible; and width: 20000px; on the parent element. There is no way to do this with CSS level 1 that I'm aware of and I refused to think I'd have to go all gung-ho with CSS level 3. The example below has 18 menus that extend beyond my 1920x1200 resolution LCD, if your screen is larger just duplicate the first tier menu elements or just resize the browser. Alternatively and with slightly lower levels of browser compatibility you could use CSS3 media queries.

Here is a full copy/paste example demonstration...

I just dealt with this problem, so I'll add my solution as a supplement on other answers given.

The problem here is that useEffect doesn't really work as you would want it to, since the call only gets triggered after the first render so there is an unwanted delay.
If you use some state manager like redux, chances are that you will get a flicker on the screen because of lingering state in the store.

What you really want is to use useLayoutEffect since this gets triggered immediately.

So I wrote a small utility function that I put in the same directory as my router:

export const callApis = (fn, path) => {
    useLayoutEffect(() => {
      fn();
    }, [path]);
};

Which I call from within the component HOC like this:

callApis(() => getTopicById({topicId}), path);

path is the prop that gets passed in the match object when using withRouter.

I'm not really in favour of listening / unlistening manually on history. That's just imo.

Sorry to tell you screencap just a simple command, only accept few arguments, but none of them can save time for you, here is the -h help output.

$ adb shell screencap -h
usage: screencap [-hp] [-d display-id] [FILENAME]
-h: this message
-p: save the file as a png.
-d: specify the display id to capture, default 0.
If FILENAME ends with .png it will be saved as a png.
If FILENAME is not given, the results will be printed to stdout.

Besides the command screencap, there is another command screenshot, I don't know why screenshot was removed from Android 5.0, but it's avaiable below Android 4.4, you can check the source from here. I didn't make my comparison which is faster between these two commands, but you can give your try in your real environment and make the final decision.

You can use the data function of the vector:

Returns a pointer to the first element in the vector.

If don't want the pointer to the first element, but by index, then you can try, for example:

//the index to the element that you want to receive its pointer:
int i = n; //(n is whatever integer you want)

std::vector<myObject> vec;
myObject* ptr_to_first = vec.data();

//or

std::vector<myObject>* vec;
myObject* ptr_to_first = vec->data();

//then

myObject element = ptr_to_first[i]; //element at index i
myObject* ptr_to_element = &element;

Update 2018

Since the original answer HTML5 validation is now supported in all modern browsers. Now the easiest way to make a field required is simply using the required attibute.

<input type="email" class="form-control" id="exampleInputEmail1" required>

or in compliant HTML5:

<input type="email" class="form-control" id="exampleInputEmail1" required="true">

Read more on Bootstrap 4 validation

In Bootstrap 3, you can apply a "validation state" class to the parent element: http://getbootstrap.com/css/#forms-control-validation

For example has-error will show a red border around the input. However, this will have no impact on the actual validation of the field. You'd need to add some additional client (javascript) or server logic to make the field required.

@AHegde - To get the tab delimited output use separator sep='\t'.

For df.to_csv:

df.to_csv(r'c:\data\pandas.txt', header=None, index=None, sep='\t', mode='a')

For np.savetxt:

np.savetxt(r'c:\data\np.txt', df.values, fmt='%d', delimiter='\t')

This is very straightforward with boolean arrays:

p31 = numpy.asarray(o31)
za = (p31 < 200).sum() # p31<200 is a boolean array, so `sum` counts the number of True elements

Do a replace first:

parseFloat(str.replace(',','.').replace(' ',''))

Same thing happened to me and I got it working doing this:

• Do not cancel the installation (using the cancel button), instead force showdown your computer so the process is killed and you get a reboot.
• After the reboot, just start the install process again.

This worked for me.

Check your build types of each project under project properties - I bet one or the other will be set to build against .NET XX - Client Profile.

With inconsistent versions, specifically with one being Client Profile and the other not, then it works at design time but fails at compile time. A real gotcha.

There is something funny going on in Visual Studio 2010 for me, which keeps setting projects seemingly randomly to Client Profile, sometimes when I create a project, and sometimes a few days later. Probably some keyboard shortcut I'm accidentally hitting...

Another thing that can cause this error is creating a model with the centering/scaling standardize function from the arm package -- m <- standardize(lm(y ~ x, data = train))

If you then try predict(m), you get the same error as in this question.

As of Python 3.5, you can merge two dicts with:

merged = {**dictA, **dictB}

(https://www.python.org/dev/peps/pep-0448/)

So:

jsonMerged = {**json.loads(jsonStringA), **json.loads(jsonStringB)}
asString = json.dumps(jsonMerged)

etc.

WebRequest being abstract (and since any inheriting class must override the Headers property).. which concrete WebRequest are you using ? In other words, how do you get that WebRequest object to beign with ?

ehr.. mnour answer made me realize that the error message you were getting is actually spot on: it's telling you that the header you are trying to add already exist and you should then modify its value using the appropriate property (the indexer, for instance), instead of trying to add it again. That's probably all you were looking for.

Other classes inheriting from WebRequest might have even better properties wrapping certain headers; See this post for instance.

Interestingly no one answers the question, OP isn't using a strongly typed int[] but an Array.

You have to cast the Array to what it actually is, an int[], then you can use ToList:

List<int> intList = ((int[])ints).ToList();

Note that Enumerable.ToList calls the list constructor that first checks if the argument can be casted to ICollection<T>(which an array implements), then it will use the more efficient ICollection<T>.CopyTo method instead of enumerating the sequence.

While changing the default behavior for Visual Studio Code requires an extension, you may override the default behavior in the workspace or user level. It works for most of the supported languages (I can guarantee HTML, JavaScript, and C#).

Workspace level

Benefits

• Does not require an extension
• Can be shared among teams

Outcomes

• .vscode/settings.json is created in the project root folder

How To?

1. Go to: Menu File → Preferences → Workspace Settings

2. Add and save "editor.formatOnType": true to settings.json (which overrides default behavior for the project you work on by creating .vscode/settings.json file).

   

User environment level

Benefits

• Does not requires extension
• Personal development environment tweeking to rule them all (settings:))

Outcomes

• User's settings.json is modified (see location by operating system below)

How To?

1. Go to: menu File → Preferences → User Settings

2. Add or change the value of "editor.formatOnType": false to "editor.formatOnType": true in the user settings.json

Your Visual Studio Code user's settings.json location is:

Settings file locations depending on your platform, the user settings file is located here:

• Windows: %APPDATA%\Code\User\settings.json
• Mac: $HOME/Library/Application Support/Code/User/settings.json
• Linux: $HOME/.config/Code/User/settings.json The workspace setting file is located under the .vscode folder in your project.

More details may be found here.

In case you want to write fallback code, decoding from base64 has been present in iOS since the very beginning by caveat of NSURL:

NSURL *URL = [NSURL URLWithString:
      [NSString stringWithFormat:@"data:application/octet-stream;base64,%@",
           base64String]];

return [NSData dataWithContentsOfURL:URL];

Like this:

import java.util.*;
Set<Integer> a = new HashSet<Integer>();
a.add( 1);
a.add( 2);
a.add( 3);

Or adding from an Array/ or multiple literals; wrap to a list, first.

Integer[] array = new Integer[]{ 1, 4, 5};
Set<Integer> b = new HashSet<Integer>();
b.addAll( Arrays.asList( b));         // from an array variable
b.addAll( Arrays.asList( 8, 9, 10));  // from literals

To get the intersection:

// copies all from A;  then removes those not in B.
Set<Integer> r = new HashSet( a);
r.retainAll( b);
// and print;   r.toString() implied.
System.out.println("A intersect B="+r);

Hope this answer helps. Vote for it!

Another option, in the host you run rsync from, set the port in the ssh config file, ie:

cat ~/.ssh/config
Host host
    Port 2222

Then rsync over ssh will talk to port 2222:

rsync -rvz --progress --remove-sent-files ./dir user@host:/path

You may use this on submit function like below.

HTML Form

<form class="form" action="" method="post">
    <input type="text" name="name" id="name" >
    <textarea name="text" id="message" placeholder="Write something to us"> </textarea>
    <input type="button" onclick="return formSubmit();" value="Send">
</form>

jQuery function:

<script>
    function formSubmit(){
        var name = document.getElementById("name").value;
        var message = document.getElementById("message").value;
        var dataString = 'name='+ name + '&message=' + message;
        jQuery.ajax({
            url: "submit.php",
            data: dataString,
            type: "POST",
            success: function(data){
                $("#myForm").html(data);
            },
            error: function (){}
        });
    return true;
    }
</script>

For any Single File Component users, here is how I set up global variable(s)

1. Assuming you are using Vue-Cli's webpack template

2. Declare your variable(s) in somewhere variable.js

   const shallWeUseVuex = false;
   

3. Export it in variable.js

   module.exports = { shallWeUseVuex : shallWeUseVuex };
   

4. Require and assign it in your vue file

   export default {
       data() {
           return {
               shallWeUseVuex: require('../../variable.js')
           };
       }
   }
   

Ref: https://vuejs.org/v2/guide/state-management.html#Simple-State-Management-from-Scratch

For some databases, you can just explicitly insert a NULL into the auto_increment column:

INSERT INTO table_name VALUES (NULL, 'my name', 'my group')

public class RemoveCharFromString {
    public static void main(String[] args) {
        String output = remove("Hello", 'l');
        System.out.println(output);
    }

    private static String remove(String input, char c) {

        if (input == null || input.length() <= 1)
            return input;
        char[] inputArray = input.toCharArray();
        char[] outputArray = new char[inputArray.length];
        int outputArrayIndex = 0;
        for (int i = 0; i < inputArray.length; i++) {
            char p = inputArray[i];
            if (p != c) {
                outputArray[outputArrayIndex] = p;
                outputArrayIndex++;
            }

        }
        return new String(outputArray, 0, outputArrayIndex);

    }
}

You can try this, using apply() function

> d
  name plate value1 value2
1    A    P1      1    100
2    B    P2      2    200
3    C    P3      3    300

> f <- function(x, output) {
 wellName <- x[1]
 plateName <- x[2]
 wellID <- 1
 print(paste(wellID, x[3], x[4], sep=","))
 cat(paste(wellID, x[3], x[4], sep=","), file= output, append = T, fill = T)
}

> apply(d, 1, f, output = 'outputfile')

What's this "other information"? An IP address?

In PHP, you use $_SERVER['REMOTE_ADDR'] to get the IP address of the remote client, then you can use gethostbyaddr() to try and conver that IP into a hostname - but not all IPs have a reverse mapping configured.

Considering the particular column Amount in the above table is of integer type. The following would be a solution :

df['Amount'] = df.Amount.fillna(0).astype(int)

Similarly, you can fill it with various data types like float, str and so on.

In particular, I would consider datatype to compare various values of the same column.

This is the simplest one.

#divid {
   position: fixed;
   top: 0;
   right: 0;
   bottom: 0;
   left: 0;
}

I suppose you don't want your textarea-content to be parsed as HTML. In this case, you can just set it as plaintext so the browser doesn't treat it as HTML and doesn't remove newlines No CSS or preprocessing required.

<script>_x000D_
function copycontent(){_x000D_
 var content = document.getElementById('ta').value;_x000D_
 document.getElementById('target').innerText = content;_x000D_
}_x000D_
</script>_x000D_
<textarea id='ta' rows='3'>_x000D_
  line 1_x000D_
  line 2_x000D_
  line 3_x000D_
</textarea>_x000D_
<button id='btn' onclick='copycontent();'>_x000D_
Copy_x000D_
</button>_x000D_
<p id='target'></p>

Chrome developer tools allows to see handshake request which stays pending during the opened connection, but you can't see traffic as far as I know. However you can sniff it for example.

Can you predict how long the user input would be?

VARCHAR(X)

Max Length: variable, up to 65,535 bytes (64KB)
Case: user name, email, country, subject, password

---

TEXT

Max Length: 65,535 bytes (64KB)
Case: messages, emails, comments, formatted text, html, code, images, links

---

MEDIUMTEXT

Max Length: 16,777,215 bytes (16MB)
Case: large json bodies, short to medium length books, csv strings

---

LONGTEXT

Max Length: 4,294,967,29 bytes (4GB)
Case: textbooks, programs, years of logs files, harry potter and the goblet of fire, scientific research logging

UPDATE If you you are using SQL 2012 new syntax was added to make this really easy. See Implement paging (skip / take) functionality with this query

I guess the most elegant is to use the ROW_NUMBER function (available from MS SQL Server 2005):

WITH NumberedMyTable AS
(
    SELECT
        Id,
        Value,
        ROW_NUMBER() OVER (ORDER BY Id) AS RowNumber
    FROM
        MyTable
)
SELECT
    Id,
    Value
FROM
    NumberedMyTable
WHERE
    RowNumber BETWEEN @From AND @To

The relative reference would be

<img src="../images/logo.png">

If you know the location relative to the root of the server, that may be simplest approach for an app with a complex nested directory hierarchy - it would be the same from all folders.

For example, if your directory tree depicted in your question is relative to the root of the server, then index.html and sub_folder/sub.html would both use:

<img src="/images/logo.png">

If the images folder is instead in the root of an application like foo below the server root (e.g. http://www.example.com/foo), then index.html (http://www.example.com/foo/index.html) e.g and sub_folder/sub.html (http://www.example.com/foo/sub_folder/sub.html) both use:

<img src="/foo/images/logo.png">

Try getting hold of a URL for your classpath resource:

URL url = this.getClass().getResource("/com/path/to/file.txt")

Then create a file using the constructor that accepts a URI:

File file = new File(url.toURI());

You can use deparse and substitute to get the name of a function argument:

myfunc <- function(v1) {
  deparse(substitute(v1))
}

myfunc(foo)
[1] "foo"

Use of Lazy quantifiers ? with no global flag is the answer.

Eg,

If you had global flag /g then, it would have matched all the lowest length matches as below.

Go to your GitHub account dashboard, find your project repository, click Settings tab - under Deploy keys you'll have to add your SSH key. Open Terminal and type:

cat ~/.ssh/id_rsa.pub | pbcopy 

This will copy the key from your id_rsa.pub file. So just go back to GitHub dashboard, paste it, click Add Key and that's it.

The same solution applies to Bitbucket accounts.

They're essentially the same... They both use swig for templating, they both use karma and mocha for tests, passport integration, nodemon, etc.

Why so similar? Mean.js is a fork of Mean.io and both initiatives were started by the same guy... Mean.io is now under the umbrella of the company Linnovate and looks like the guy (Amos Haviv) stopped his collaboration with this company and started Mean.js. You can read more about the reasons here.

Now... main (or little) differences you can see right now are:

SCAFFOLDING AND BOILERPLATE GENERATION

Mean.io uses a custom cli tool named 'mean'
Mean.js uses Yeoman Generators

MODULARITY

Mean.io uses a more self-contained node packages modularity with client and server files inside the modules.
Mean.js uses modules just in the front-end (for angular), and connects them with Express. Although they were working on vertical modules as well...

BUILD SYSTEM

Mean.io has recently moved to gulp
Mean.js uses grunt

DEPLOYMENT

Both have Dockerfiles in their respective repos, and Mean.io has one-click install on Google Compute Engine, while Mean.js can also be deployed with one-click install on Digital Ocean.

DOCUMENTATION

Mean.io has ok docs
Mean.js has AWESOME docs

COMMUNITY

Mean.io has a bigger community since it was the original boilerplate
Mean.js has less momentum but steady growth

On a personal level, I like more the philosophy and openness of MeanJS and more the traction and modules/packages approach of MeanIO. Both are nice, and you'll end probably modifying them, so you can't really go wrong picking one or the other. Just take them as starting point and as a learning exercise.

ALTERNATIVE “MEAN” SOLUTIONS

MEAN is a generic way (coined by Valeri Karpov) to describe a boilerplate/framework that takes "Mongo + Express + Angular + Node" as the base of the stack. You can find frameworks with this stack that use other denomination, some of them really good for RAD (Rapid Application Development) and building SPAs. Eg:

• Meteor. Now with official Angular support, represents a great MEAN stack
• StrongLoop Loopback (main Node.js core contributors and Express maintainers)
• Generator Angular Fullstack
• Sails.js
• Cleverstack
• Deployd, etc (there are more)

You also have Hackathon Starter. It doesn't have A of MEAN (it is 'MEN'), but it rocks..

Have fun!

I've added a "Connected Service" to our project by Visual Studio which generated a default method to create Client.

var client = new MyWebService.Client(MyWebService.Client.EndpointConfiguration.MyPort, _endpointUrl);

This constructor inherits ClientBase and behind the scene is creating Binding by using its own method Client.GetBindingForEndpoint(endpointConfiguration):

public Client(EndpointConfiguration endpointConfiguration, string remoteAddress) :
            base(Client.GetBindingForEndpoint(endpointConfiguration), 
                 new System.ServiceModel.EndpointAddress(remoteAddress))

This method has different settings for https service and http service. When you want get data from http, you should use TransportCredentialOnly:

System.ServiceModel.BasicHttpBinding result = new System.ServiceModel.BasicHttpBinding();
result.Security.Mode = System.ServiceModel.BasicHttpSecurityMode.TransportCredentialOnly;
 

For https you should use Transport:

result.Security.Mode = System.ServiceModel.BasicHttpSecurityMode.Transport;

For all those using Ubuntu with ppa:ondrej/php PPA this will fix the problem:

apt install php7.0-mbstring php7.0-zip php7.0-xml

(see https://launchpad.net/~ondrej/+archive/ubuntu/php)

Thanks @Alexandre Barbosa for pointing this out!

EDIT 20160423:

One-liner to fix this issue:

sudo add-apt-repository -y ppa:ondrej/php && sudo apt update && sudo apt install -y php7.0-mbstring php7.0-zip php7.0-xml

(this will add the ppa noted above and will also make sure you always have the latest php. We use Ondrej's PHP ppa for almost two years now and it's working like charm)

If slicing could work on iterators...

from itertools import islice
with open(fname) as f:
    for line in islice(f, 1, None):
        pass

Old question but this answer might help someone.

If you are trying to display the contents of the container outside of the boundaries of the container, make sure that it doesn't have overflow:hidden, otherwise anything outside of it will be cut off.

Instead of using datetime.now you should be really using from django.utils.timezone import now

Reference:

• Documentation for django.utils.timezone.now

so go for something like this:

from django.utils.timezone import now


created_date = models.DateTimeField(default=now, editable=False)

I had the same issue, and it ended up being a problem with the php max post size. Increasing it solved the problem.

A simple inline JavaScript confirm would suffice:

<form onsubmit="return confirm('Do you really want to submit the form?');">

No need for an external function unless you are doing validation, which you can do something like this:

<script>
function validate(form) {

    // validation code here ...


    if(!valid) {
        alert('Please correct the errors in the form!');
        return false;
    }
    else {
        return confirm('Do you really want to submit the form?');
    }
}
</script>
<form onsubmit="return validate(this);">

Currently, and with the new versions of Mysql can insert the current date automatically without adding a code in your PHP file. You can achieve that from Mysql while setting up your database as follows:

Now, any new post will automatically get a unique date and time. Hope this can help.

Here's an example that looks for certain HTML tags so it's clear that /someregex/.test() returns a boolean:

if(/(span|h[0-6]|li|a)/i.test("h3")) alert('true');

My problem was fideloper proxy version.

when i upgraded laravel 5.5 to 5.8 this happened

just sharing if anybody get help

change you composer json fideloper version:

"fideloper/proxy": "^4.0",

After that you need to run update composer that's it.

composer update

This is how you can submit your form to a specific controller and action method in Razor.

 <input type="submit" value="Upload" onclick="location.href='@Url.Action("ActionName", "ControllerName")'" />

As MultiPartEntity is deprecated. So here is the new way to do it! And you only need httpcore.jar(latest) and httpmime.jar(latest) download them from Apache site.

try

    HttpClient client = new DefaultHttpClient();
    HttpPost post = new HttpPost(URL);

    MultipartEntityBuilder entityBuilder = MultipartEntityBuilder.create();
    entityBuilder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);

    entityBuilder.addTextBody(USER_ID, userId);
    entityBuilder.addTextBody(NAME, name);
    entityBuilder.addTextBody(TYPE, type);
    entityBuilder.addTextBody(COMMENT, comment);
    entityBuilder.addTextBody(LATITUDE, String.valueOf(User.Latitude));
    entityBuilder.addTextBody(LONGITUDE, String.valueOf(User.Longitude));

    if(file != null)
    {
        entityBuilder.addBinaryBody(IMAGE, file);
    }

    HttpEntity entity = entityBuilder.build();
    post.setEntity(entity);
    HttpResponse response = client.execute(post);
    HttpEntity httpEntity = response.getEntity();
    result = EntityUtils.toString(httpEntity);
    Log.v("result", result);
}
catch(Exception e)
{
    e.printStackTrace();

To add a small bit to Sydius' answer, smart pointers will often provide a more stable solution by catching many easy to make errors. Raw pointers will have some perfromance advantages and can be more flexible in certain circumstances. You may also be forced to use raw pointers when linking into certain 3rd party libraries.

Your thread's locale is set to one in which the decimal mark is "," instead of ".".

Try using this:

float.Parse("41.00027357629127", CultureInfo.InvariantCulture.NumberFormat);

Note, however, that a float cannot hold that many digits of precision. You would have to use double or Decimal to do so.

I would also suggest extending TextView and other controls, but it would be better I consider to set up font in constructs.

public FontTextView(Context context) {
    super(context);
    init();
}

public FontTextView(Context context, AttributeSet attrs) {
    super(context, attrs);
    init();
}

public FontTextView(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
    init();
}

protected void init() {
    setTypeface(Typeface.createFromAsset(getContext().getAssets(), AppConst.FONT));
}

Try ^CTR.\*, which literally means start of line, CTR, anything.

This will be case-sensitive, and setting non-case-sensitivity will depend on your programming language, or use ^[Cc][Tt][Rr].\* if cross-environment case-insensitivity matters.

As with @user3006381 above, my issue was not just relative URLs but that webpack was placing the files as if they were javascript files. Their contents were all basically:

module.exports = __webpack_public_path__ + "7410dd7fd1616d9a61625679285ff5d4.eot";

in the fonts directory instead of the real fonts and the font files were in the output folder under hash codes. To fix this, I had to change the test on my url-loader (in my case my image processor) to not load the fonts folder. I still had to set output.publicPath in webpack.config.js as @will-madden notes in his excellent answer.

Try instead of db.parse(xml):

Document doc = db.parse(new InputSource(new StringReader(**xml**)));

Just for sake of completeness, you can also use the same technique above with excel tables.

In the example below, I'm looking of a text in any cell of a Excel Table named "tblConfig", place in the sheet named Config that normally is set to be hidden. I'm accepting the defaults of the Find method.

Dim list As ListObject
Dim config As Worksheet
Dim cell as Range


Set config = Sheets("Config")
Set list = config.ListObjects("tblConfig")

'search in any cell of the data range of excel table
Set cell = list.DataBodyRange.Find(searchTerm)

If cell Is Nothing Then
    'when information is not found
Else
    'when information is found
End If

You can use .toggle() function instead of .click()....

Syntax: ALTER TABLE table_name CHANGE old_column_name new_column_name datatype;

If table name is Student and column name is Name. Then, if you want to change Name to First_Name

ALTER TABLE Student CHANGE Name First_Name varchar(20);

I think the result for those two should always be the same. The difference is that you need an instance of the class to use isInstance but just the Class object to use isAssignableFrom.

Example code:

a = pd.Series([1,2,3,4], index=[7,2,8,9])
b = pd.Series([5,6,7,8], index=[7,2,8,9])
data = pd.DataFrame({'a': a,'b':b, 'idx_col':a.index})

Pandas allows you to create a DataFrame from a dict with Series as the values and the column names as the keys. When it finds a Series as a value, it uses the Series index as part of the DataFrame index. This data alignment is one of the main perks of Pandas. Consequently, unless you have other needs, the freshly created DataFrame has duplicated value. In the above example, data['idx_col'] has the same data as data.index.

Simply think of eval as "evaluating your expression one additional time before execution"

eval echo \${$n} becomes echo $1 after the first round of evaluation. Three changes to notice:

• The \$ became $ (The backslash is needed, otherwise it tries to evaluate ${$n}, which means a variable named {$n}, which is not allowed)
• $n was evaluated to 1
• The eval disappeared

In the second round, it is basically echo $1 which can be directly executed.

So eval <some command> will first evaluate <some command> (by evaluate here I mean substitute variables, replace escaped characters with the correct ones etc.), and then run the resultant expression once again.

eval is used when you want to dynamically create variables, or to read outputs from programs specifically designed to be read like this. See http://mywiki.wooledge.org/BashFAQ/048 for examples. The link also contains some typical ways in which eval is used, and the risks associated with it.

Here's the workflow I use all the time, using the keyboard only

1. Ctrl/Cmd + A Select All
2. Ctrl/Cmd + Shift + L Split into Lines
3. ' Surround every line with quotes

Note that this doesn't work if there are blank lines in the selection.

I found an example in this Kubernetes client where they were using X509VerificationFlags.AllowUnknownCertificateAuthority to trust self-signed self-signed root certificates. I slightly reworked their example to work with our own PEM encoded root certificates. Hopefully this helps someone.

  using System;
  using System.Collections.Generic;
  using System.Linq;
  using System.Net.Security;
  using System.Security.Cryptography.X509Certificates;

  /// </summary>
  public class HttpClientHandler : System.Net.Http.HttpClientHandler
  {
    /// <summary>
    /// Initializes a new instance of the <see cref="HttpClientHandler"/> class.
    /// </summary>
    /// <param name="pemRootCerts">The PEM encoded root certificates to trust.</param>
    public HttpClientHandler(IEnumerable<string> pemRootCerts)
    {
      foreach (var pemRootCert in pemRootCerts)
      {
        var text = pemRootCert.Trim();
        text = text.Replace("-----BEGIN CERTIFICATE-----", string.Empty);
        text = text.Replace("-----END CERTIFICATE-----", string.Empty);
        this.rootCerts.Add(new X509Certificate2(Convert.FromBase64String(text)));
      }

      this.ServerCertificateCustomValidationCallback = this.VerifyServerCertificate;
    }

    private bool VerifyServerCertificate(
      object sender,
      X509Certificate certificate,
      X509Chain chain,
      SslPolicyErrors sslPolicyErrors)
    {
      // If the certificate is a valid, signed certificate, return true.
      if (sslPolicyErrors == SslPolicyErrors.None)
      {
        return true;
      }

      // If there are errors in the certificate chain, look at each error to determine the cause.
      if ((sslPolicyErrors & SslPolicyErrors.RemoteCertificateChainErrors) != 0)
      {
        chain.ChainPolicy.RevocationMode = X509RevocationMode.NoCheck;

        // add all your extra certificate chain
        foreach (var rootCert in this.rootCerts)
        {
          chain.ChainPolicy.ExtraStore.Add(rootCert);
        }

        chain.ChainPolicy.VerificationFlags = X509VerificationFlags.AllowUnknownCertificateAuthority;
        var isValid = chain.Build((X509Certificate2)certificate);

        var rootCertActual = chain.ChainElements[chain.ChainElements.Count - 1].Certificate;
        var rootCertExpected = this.rootCerts[this.rootCerts.Count - 1];
        isValid = isValid && rootCertActual.RawData.SequenceEqual(rootCertExpected.RawData);

        return isValid;
      }

      // In all other cases, return false.
      return false;
    }

    private readonly IList<X509Certificate2> rootCerts = new List<X509Certificate2>();
  }
}

Everything in a Java program not explicitly set to something by the programmer, is initialized to a zero value.

• For references (anything that holds an object) that is null.
• For int/short/byte/long that is a 0.
• For float/double that is a 0.0
• For booleans that is a false.
• For char that is the null character '\u0000' (whose decimal equivalent is 0).

When you create an array of something, all entries are also zeroed. So your array contains five zeros right after it is created by new.

Note (based on comments): The Java Virtual Machine is not required to zero out the underlying memory when allocating local variables (this allows efficient stack operations if needed) so to avoid random values the Java Language Specification requires local variables to be initialized.

Send the passwordbox control as a parameter to your login command.

<Button Command="{Binding LoginCommand}" CommandParameter="{Binding ElementName=PasswordBox}"...>

Then you can call CType(parameter, PasswordBox).Password in your viewmodel.

MySql decimal types are a little bit more complicated than just left-of and right-of the decimal point.

The first argument is precision, which is the number of total digits. The second argument is scale which is the maximum number of digits to the right of the decimal point.

Thus, (4,2) can be anything from -99.99 to 99.99.

As for why you're getting 99.99 instead of the desired 3.80, the value you're inserting must be interpreted as larger than 99.99, so the max value is used. Maybe you could post the code that you are using to insert or update the table.

Edit

Corrected a misunderstanding of the usage of scale and precision, per http://dev.mysql.com/doc/refman/5.0/en/numeric-types.html.

A scriptable object is an object that records the operations done to it and it can store them as a "script" which can be replayed.

For example, see: Application Scripting Framework

Now, if Alistair didn't know what he asked and really meant "subscriptable" objects (as edited by others), then (as mipadi also answered) this is the correct one:

A subscriptable object is any object that implements the __getitem__ special method (think lists, dictionaries).

For android 4.2, dont forget to add @JavascriptInterface to all javasscript functions

I want to add to Michael Berkowski's answer that this can also happen if the array's order is reversed, in which case it's a bit trickier to observe the issue, because in the json object, the order will be ordered ascending.

For example:

[
    3 => 'a',
    2 => 'b',
    1 => 'c',
    0 => 'd'
]

Will return:

{
    0: 'd',
    1: 'c',
    2: 'b',
    3: 'a'
}

So the solution in this case, is to use array_reverse before encoding it to json

The issue here is that you just Added the reference to System.IO.Compression it is missing the reference to System.IO.Compression.Filesystem.dll

And you need to do it on .net 4.5 or later (because it doesn't exist on older versions).

I just posted a script on TechNet Maybe somebody would find it useful it requires .net 4.5 or 4.7

https://gallery.technet.microsoft.com/scriptcenter/Create-a-Zip-file-from-a-b23a7530

It might be obvious, but make sure that you are sending to the parser URL object not a String containing www adress. This will not work:

    ObjectMapper mapper = new ObjectMapper();
    String www = "www.sample.pl";
    Weather weather = mapper.readValue(www, Weather.class);

But this will:

    ObjectMapper mapper = new ObjectMapper();
    URL www = new URL("http://www.oracle.com/");
    Weather weather = mapper.readValue(www, Weather.class);

I've seen this error while trying to access a column value after processing the resultset.

if (rs != null) {
  while (rs.next()) {
    count = rs.getInt(1);
  }
  count = rs.getInt(1); //this will throw Exhausted resultset
}

Hope this will help you :)

Usually in ruby when you are looking for "type" you are actually wanting the "duck-type" or "does is quack like a duck?". You would see if it responds to a certain method:

@some_var.respond_to?(:each)

You can iterate over @some_var because it responds to :each

If you really want to know the type and if it is Hash or Array then you can do:

["Hash", "Array"].include?(@some_var.class)  #=> check both through instance class
@some_var.kind_of?(Hash)    #=> to check each at once
@some_var.is_a?(Array)   #=> same as kind_of

The best approach for this sort of thing is probably git rebase. It allows you to pull changes from master into your development branch, but leave all of your development work "on top of" (later in the commit log) the stuff from master. When your new work is complete, the merge back to master is then very straightforward.

I worked on this same issue and I am sure I have found out the exact reason for it.

Neither BindingResult nor plain target object for bean name 'command' available as request attribute

If your successView property value (name of jsp page) is the same as your input page name, then second value of ModelAndView constructor must be match with the commandName of the input page.

setting the overflow should take care of it, but you need to set the height of Content also. If the height attribute is not set, the div will grow vertically as tall as it needs to, and scrollbars wont be needed.

See Example: http://jsfiddle.net/ftkbL/1/

100% result solution in Javascript:

function solution(A) {
    // only positive values, sorted
    A = A.filter(x => x >= 1).sort((a, b) => a - b)

    let x = 1

    for(let i = 0; i < A.length; i++) {
        // if we find a smaller number no need to continue, cause the array is sorted
        if(x < A[i]) {
            return x
        }
        x = A[i] + 1
    }

    return x
}

after you add the user for testing. the user should get an email. open that email by your iOS device, then click "Start testing" it will bring you to testFlight to download the app directly. If you open that email via computer, and then click "Start testing" it will show you another page which have the instruction of how to install the app. and that invitation code is on the last line. those All upper case letters is the code.

The HTML code:

<input type="radio" name="theName" value="1" id="option-1">
<input type="radio" name="theName" value="2">
<input type="radio" name="theName" value="3">

The Javascript code:

$(document).ready(function(){
    $('input[name="theName"]').change(function(){
        if($('#option-1').prop('checked')){
            alert('Option 1 is checked!');
        }else{
            alert('Option 1 is unchecked!');
        }
    });
});

In multiple radio with name "theName", detect when option 1 is checked or unchecked. Works in all situations: on click control, use the keyboard, use joystick, automatic change the values from other dinamicaly function, etc.

You want to use timeout. timeout 10 will sleep 10 seconds

I know this is old, I had a case where I needed the array key to be included in the CSV also, so I updated the script by Jesse Q to do that. I used a string as output, as implode can't add new line (new line is something I added, and should really be there).

Please note, this only works with single value arrays (key, value). but could easily be updated to handle multi-dimensional (key, array()).

function arrayToCsv( array &$fields, $delimiter = ',', $enclosure = '"', $encloseAll = false, $nullToMysqlNull = false ) {
    $delimiter_esc = preg_quote($delimiter, '/');
    $enclosure_esc = preg_quote($enclosure, '/');

    $output = '';
    foreach ( $fields as $key => $field ) {
        if ($field === null && $nullToMysqlNull) {
            $output = '';
            continue;
        }

        // Enclose fields containing $delimiter, $enclosure or whitespace
        if ( $encloseAll || preg_match( "/(?:${delimiter_esc}|${enclosure_esc}|\s)/", $field ) ) {
            $output .= $key;
            $output .= $delimiter;
            $output .= $enclosure . str_replace($enclosure, $enclosure . $enclosure,     $field) . $enclosure;
            $output .= PHP_EOL;
        }
        else {
            $output .= $key;
            $output .= $delimiter;
            $output .= $field;
            $output .= PHP_EOL;
        }
    }

    return  $output ;
}

You can do something like

@NamedQuery(name="IssueDescriptor.findByIssueDescriptorId" ,

    query=" select new com.test.live.dto.IssuesDto (idc.id, dep.department, iss.issueName, 
               cat.issueCategory, idc.issueDescriptor, idc.description) 
            from Department dep 
            inner join dep.issues iss 
            inner join iss.category cat 
            inner join cat.issueDescriptor idc 
            where idc.id in(?1)")

And there must be Constructor like

public IssuesDto(long id, String department, String issueName, String issueCategory, String issueDescriptor,
            String description) {
        super();
        this.id = id;
        this.department = department;
        this.issueName = issueName;
        this.issueCategory = issueCategory;
        this.issueDescriptor = issueDescriptor;
        this.description = description;
    }

One liner for callstack:

begin; Whatever.you.want; rescue => e; puts e.message; puts; puts e.backtrace; end

One liner for callstack without all the gems's:

begin; Whatever.you.want; rescue => e; puts e.message; puts; puts e.backtrace.grep_v(/\/gems\//); end

One liner for callstack without all the gems's and relative to current directory

begin; Whatever.you.want; rescue => e; puts e.message; puts; puts e.backtrace.grep_v(/\/gems\//).map { |l| l.gsub(`pwd`.strip + '/', '') }; end

if you are already using jQuery in your build just do this:

$(yourObject).length

It works nicely for me on objects, and I already had jQuery as a dependancy.

Python's mmap module will allow you to insert into a file. The following sample shows how it can be done in Unix (Windows mmap may be different). Note that this does not handle all error conditions and you might corrupt or lose the original file. Also, this won't handle unicode strings.

import os
from mmap import mmap

def insert(filename, str, pos):
    if len(str) < 1:
        # nothing to insert
        return

    f = open(filename, 'r+')
    m = mmap(f.fileno(), os.path.getsize(filename))
    origSize = m.size()

    # or this could be an error
    if pos > origSize:
        pos = origSize
    elif pos < 0:
        pos = 0

    m.resize(origSize + len(str))
    m[pos+len(str):] = m[pos:origSize]
    m[pos:pos+len(str)] = str
    m.close()
    f.close()

It is also possible to do this without mmap with files opened in 'r+' mode, but it is less convenient and less efficient as you'd have to read and temporarily store the contents of the file from the insertion position to EOF - which might be huge.

In the shell, you can't execute more than one statement at a time:

>>> x = 5
y = 6
SyntaxError: multiple statements found while compiling a single statement

You need to execute them one by one:

>>> x = 5
>>> y = 6
>>>

When you see multiple statements are being declared, that means you're seeing a script, which will be executed later. But in the interactive interpreter, you can't do more than one statement at a time.

jQuery.fn.outerHTML = function() {
    return $(this).clone().wrap('<div>').parent().html();
};
$('input#password').replaceWith($('input.password').outerHTML().replace(/text/g,'password'));

This answer is an update with a little more consideration for OOM and various other leaks.

Assumes you have a directory intended as the destination and a name String already defined.

    File destination = new File(directory.getPath() + File.separatorChar + filename);

    ByteArrayOutputStream bytes = new ByteArrayOutputStream();
    source.compress(Bitmap.CompressFormat.PNG, 100, bytes);

    FileOutputStream fo = null;
    try {
        destination.createNewFile();

        fo = new FileOutputStream(destination);
        fo.write(bytes.toByteArray());
    } catch (IOException e) {

    } finally {
        try {
            fo.close();
        } catch (IOException e) {}
    }

Cloning an input stream might not be a good idea, because this requires deep knowledge about the details of the input stream being cloned. A workaround for this is to create a new input stream that reads from the same source again.

So using some Java 8 features this would look like this:

public class Foo {

    private Supplier<InputStream> inputStreamSupplier;

    public void bar() {
        procesDataThisWay(inputStreamSupplier.get());
        procesDataTheOtherWay(inputStreamSupplier.get());
    }

    private void procesDataThisWay(InputStream) {
        // ...
    }

    private void procesDataTheOtherWay(InputStream) {
        // ...
    }
}

This method has the positive effect that it will reuse code that is already in place - the creation of the input stream encapsulated in inputStreamSupplier. And there is no need to maintain a second code path for the cloning of the stream.

On the other hand, if reading from the stream is expensive (because a it's done over a low bandwith connection), then this method will double the costs. This could be circumvented by using a specific supplier that will store the stream content locally first and provide an InputStream for that now local resource.

While it's impossible to set a blur radius directly on UILabel, you definitely could change it by manipulating CALayer.

Just set:

//Required properties
customLabel.layer.shadowRadius = 5.0 //set shadow radius to your desired value.
customLabel.layer.shadowOpacity = 1.0 //Choose an opacity. Make sure it's visible (default is 0.0)

//Other options
customLabel.layer.shadowOffset = CGSize(width: 10, height: 10)
customLabel.layer.shadowColor = UIColor.black.cgColor
customLabel.layer.masksToBounds = false

What I hope will help someone and other answers failed to clarify is that it will not work if you also set UILabel Shadow Color property directly on Interface Builder while trying to setup .layer.shadowRadius.

So if setting label.layer.shadowRadius didn't work, please verify Shadow Color for this UILabel on Interface Builder. It should be set to default. And then, please, if you want a shadow color other than black, set this color also through .layer property.

I'll add another possible solution here, which is what worked in my case.

I found there was a process called SpiceWorksEventProcessor running, which was tying up port 5555, and apparently being read by adb as an emulator. Killing that process was what finally removed that stubborn emulator device for me.

I'm not sure what this thing is, but if you have it, it might be the cause of your offline emulator.

Cheers

From what I understand you want to make a navigation bar or something similar to it. What I recommend doing is making a list and editing the items from there. Just try this;

<ul>
    <li class='item col-md-12 panel' id='gameplay-title'>Title</li>
    <li class='item col-md-6 col-md-offset-3 panel' id='gameplay-scoreboard'>Scoreboard</li>
</ul>

And so on... To add more categories add another ul in there. Now, for the CSS you just need this;

ul {
    list-style: none;
}
.item {
    display: inline;
    padding-right: 20px;
}

You can fix the rounding by subtracting 0.5 for toFixed, e.g.

(f - 0.005).toFixed(2)

The short answer is: don't. (...) You really can't. And that's a good thing

I'd like to set the record straight regarding this:

NodeJS does support Synchronous Requests. It wasn't designed to support them out of the box, but there are a few workarounds if you are keen enough, here is an example:

var request = require('sync-request'),
    res1, res2, ucomp, vcomp;

try {
    res1 = request('GET', base + u_ext);
    res2 = request('GET', base + v_ext);
    ucomp = res1.split('\n')[1].split(', ')[1];
    vcomp = res2.split('\n')[1].split(', ')[1];
    doSomething(ucomp, vcomp);

} catch (e) {}

When you pop the hood open on the 'sync-request' library you can see that this runs a synchronous child process in the background. And as is explained in the sync-request README it should be used very judiciously. This approach locks the main thread, and that is bad for performance.

However, in some cases there is little or no advantage to be gained by writing an asynchronous solution (compared to the certain harm you are doing by writing code that is harder to read).

This is the default assumption held by many of the HTTP request libraries in other languages (Python, Java, C# etc), and that philosophy can also be carried to JavaScript. A language is a tool for solving problems after all, and sometimes you may not want to use callbacks if the benefits outweigh the disadvantages.

For JavaScript purists this may rankle of heresy, but I'm a pragmatist so I can clearly see that the simplicity of using synchronous requests helps if you find yourself in some of the following scenarios:

1. Test Automation (tests are usually synchronous by nature).

2. Quick API mash-ups (ie hackathon, proof of concept works etc).

3. Simple examples to help beginners (before and after).

Be warned that the code above should not be used for production. If you are going to run a proper API then use callbacks, use promises, use async/await, or whatever, but avoid synchronous code unless you want to incur a significant cost for wasted CPU time on your server.

Before trying to consume your json object with another object just check that the api is returning raw json via the browser api/rootobject, for my case i found out that the underlying data provider mssqlserver was not running and throw an unhanded exception !

as simple as that :)

Interpretation for the author

var o = JObject.Parse(response);
var a = o.SelectToken("data").Select(jt => jt.ToObject<TheUser>()).ToList();

I just had the same problem after accepting a Java update--scores of build errors and android import not recognized. On checking the build path in Project=>Properties, I found that the check box for Android 4.3 had somehow gotten cleared. Checking it resolved all the import errors without my even having to restart the IDE or run a project clean.

Suppose you have a button that when pressed sets n to 5, you could then generate labels and textboxes on your form like so.

var n = 5;
for (int i = 0; i < n; i++)
{
    //Create label
    Label label = new Label();
    label.Text = String.Format("Label {0}", i);
    //Position label on screen
    label.Left = 10;
    label.Top = (i + 1) * 20;
    //Create textbox
    TextBox textBox = new TextBox();
    //Position textbox on screen
    textBox.Left = 120;
    textBox.Top = (i + 1) * 20;
    //Add controls to form
    this.Controls.Add(label);
    this.Controls.Add(textBox);
}

This will not only add them to the form but position them decently as well.

You can try changing it to this:

If myTableData.Rows.Count > 0 Then
  For i As Integer = 0 To myTableData.Rows.Count - 1
    ''Dim DataType() As String = myTableData.Rows(i).Item(1)
    ListBox2.Items.Add(myTableData.Rows(i)(1))
  Next
End If

Note: Your loop needs to be one less than the row count since it's a zero-based index.

According to the documentation: https://jinja.palletsprojects.com/en/2.10.x/templates/#line-statements you may use multi-line statements as long as the code has parens/brackets around it. Example:

{% if ( (foo == 'foo' or bar == 'bar') and 
        (fooo == 'fooo' or baar == 'baar') ) %}
    <li>some text</li>
{% endif %}

Edit: Using line_statement_prefix = '#'* the code would look like this:

# if ( (foo == 'foo' or bar == 'bar') and 
       (fooo == 'fooo' or baar == 'baar') )
    <li>some text</li>
# endif

*Here's an example of how you'd specify the line_statement_prefix in the Environment:

from jinja2 import Environment, PackageLoader, select_autoescape
env = Environment(
    loader=PackageLoader('yourapplication', 'templates'),
    autoescape=select_autoescape(['html', 'xml']),
    line_statement_prefix='#'
)

Or using Flask:

from flask import Flask
app = Flask(__name__, instance_relative_config=True, static_folder='static')
app.jinja_env.filters['zip'] = zip
app.jinja_env.line_statement_prefix = '#'

I recently discovered that using strtolower() can cause issues where the data is truncated after a special character.

The solution was to use

mb_strtolower($string, 'UTF-8');

mb_ uses MultiByte. It supports more characters but in general is a little slower.

• You can also unpack the axes in the subplots call

• And set whether you want to share the x and y axes between the subplots

Like this:

import matplotlib.pyplot as plt
fig, ((ax1, ax2), (ax3, ax4)) = plt.subplots(nrows=2, ncols=2, sharex=True, sharey=True)
ax1.plot(range(10), 'r')
ax2.plot(range(10), 'b')
ax3.plot(range(10), 'g')
ax4.plot(range(10), 'k')
plt.show()

The lambda you pass to Where can include any normal C# code, for example the && operator:

.Where(l => l.Title != string.Empty && l.InternalName != string.Empty)

Use (eventName) for while binding event to DOM, basically () is used for event binding. Also use ngModel to get two way binding for myModel variable.

Markup

<input type="text" [(ngModel)]="myModel" (blur)="onBlurMethod()">

Code

export class AppComponent { 
  myModel: any;
  constructor(){
    this.myModel = '123';
  }
  onBlurMethod(){
   alert(this.myModel) 
  }
}

Demo

Alternative(not preferable)

<input type="text" #input (blur)="onBlurMethod($event.target.value)">

Demo

For model driven form to fire validation on blur, you could pass updateOn parameter.

ctrl = new FormControl('', {
   updateOn: 'blur', //default will be change
   validators: [Validators.required]
});

Some good answers here regarding the noted "types".

I submit some additional, more "exotic" concepts often associated with the functional programming crowd:

• Domain Specific Language or DSL Programming: creating a new language to deal with the problem at hand.
• Meta-Programming: when your program writes other programs.
• Evolutionary Programming: where you build a system that continually improves itself or generates successively better generations of sub-programs.

@Bruno Lavit has a great answer, but if you want you can just access the log and download it as txt file to your workspace from the job's URL:

${BUILD_URL}/consoleText

Then it's only a matter of downloading this page to your ${Workspace}

• You can use "Invoke ANT" and use the GET target
• On Linux you can use wget to download it to your workspace
• etc.

Good luck!

Edit: The actual log file on the file system is not on the slave, but kept in the Master machine. You can find it under: $JENKINS_HOME/jobs/$JOB_NAME/builds/lastSuccessfulBuild/log

If you're looking for another build just replace lastSuccessfulBuild with the build you're looking for.

Solution for those who are interested in sending params and headers in GET request

$http.get('https://www.your-website.com/api/users.json', {
        params:  {page: 1, limit: 100, sort: 'name', direction: 'desc'},
        headers: {'Authorization': 'Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ=='}
    }
)
.then(function(response) {
    // Request completed successfully
}, function(x) {
    // Request error
});

Complete service example will look like this

var mainApp = angular.module("mainApp", []);

mainApp.service('UserService', function($http, $q){

   this.getUsers = function(page = 1, limit = 100, sort = 'id', direction = 'desc') {

        var dfrd = $q.defer();
        $http.get('https://www.your-website.com/api/users.json', 
            {
                params:{page: page, limit: limit, sort: sort, direction: direction},
                headers: {Authorization: 'Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ=='}
            }
        )
        .then(function(response) {
            if ( response.data.success == true ) { 

            } else {

            }
        }, function(x) {

            dfrd.reject(true);
        });
        return dfrd.promise;
   }

});

If you need something like:

  ¦ A                              ¦ B
--+--------------------------------+---
1 ¦ #My comment, something else    ¦
2 ¦ 1                              ¦ 2

Your CSV may contain the following lines:

"#My comment, something else"
1,2

Pay close attention at the 'quotes' in the first line.

When converting your text to columns using the Excel wizard, remember checking the 'Treat consecutive delimiters as one', setting it to use 'quotes' as delimiter.

Thus, Excel will split the text at the commas, keeping the 'comment' line as a single column value (and it will remove the quotes).

"I want a Bitmap d, that is grayscale. I do see a consructor that includes System.Drawing.Imaging.PixelFormat, but I don't understand how to use that."

Here is how to do this

Bitmap grayScaleBP = new 
         System.Drawing.Bitmap(2, 2, System.Drawing.Imaging.PixelFormat.Format16bppGrayScale);

EDIT: To convert to grayscale

             Bitmap c = new Bitmap("fromFile");
             Bitmap d;
             int x, y;

             // Loop through the images pixels to reset color.
             for (x = 0; x < c.Width; x++)
             {
                 for (y = 0; y < c.Height; y++)
                 {
                     Color pixelColor = c.GetPixel(x, y);
                     Color newColor = Color.FromArgb(pixelColor.R, 0, 0);
                     c.SetPixel(x, y, newColor); // Now greyscale
                 }
             }
            d = c;   // d is grayscale version of c

public static Bitmap MakeGrayscale3(Bitmap original)

The Visual Studio debugger comes with four standard visualizers. These are the text, HTML, and XML visualizers, all of which work on string objects, and the dataset visualizer, which works for DataSet, DataView, and DataTable objects.

To use it, break into your code, mouse over your DataSet, expand the quick watch, view the Tables, expand that, then view Table[0] (for example). You will see something like {Table1} in the quick watch, but notice that there is also a magnifying glass icon. Click on that icon and your DataTable will open up in a grid view.

Here I have a solution that avoid multiple requests, for loops and old document removal.

You can easily create a new idea manually using something like:_id:ObjectId() But knowing Mongo will automatically assign an _id if missing, you can use aggregate to create a $project containing all the fields of your document, but omit the field _id. You can then save it with $out

So if your document is:

{
"_id":ObjectId("5b5ed345cfbce6787588e480"),
"title": "foo",
"description": "bar"
}

Then your query will be:

    db.getCollection('myCollection').aggregate([
        {$match:
             {_id: ObjectId("5b5ed345cfbce6787588e480")}
        }        
        {$project:
            {
             title: '$title',
             description: '$description'             
            }     
        },
        {$out: 'myCollection'}
    ])

Replace

var result= string.search(/searchstring/i);

with

var result= string.search(new RegExp(searchstring, "i"));

List<Object> object = new List<Object>();

You cannot do this because List is an interface and you cannot create object of any interface or in other word you cannot instantiate any interface. Moreover, you can assign any object of class which implements List to its reference variable. For example you can do this:

list<Object> object = new ArrayList<Object>();

Here ArrayList is a class which implements List, you can use any class which implements List.

I was playing around with the same thing and worked this up. It's not fully tested but seems to handle the issue with value types (the unaryexpression issue you ran into)

public static string GetName(Expression<Func<object>> exp)
{
    MemberExpression body = exp.Body as MemberExpression;

    if (body == null) {
       UnaryExpression ubody = (UnaryExpression)exp.Body;
       body = ubody.Operand as MemberExpression;
    }

    return body.Member.Name;
}

For Node.js there is Nodeclipse 0.2 with some bug fixes for chromedevtools

Use a static AutoResetEvent in your spawned threads to call back to the main thread using the Set() method. This guy has a fairly good demo in SO on how to use it.

AutoResetEvent clarification

I get the following when I try it:

>> Date.today.to_time.to_i
=> 1259244000
>> Time.now.to_i
=> 1259275709

The difference between these two numbers is due to the fact that Date does not store the hours, minutes or seconds of the current time. Converting a Date to a Time will result in that day, midnight.

Use Intent Preference if you are using preference xml screen or you if you are using you custom screen then the code would be like below

intentClearCookies = getPreferenceManager().createPreferenceScreen(this);
    Intent clearcookies = new Intent(PopupPostPref.this, ClearCookies.class);

    intentClearCookies.setIntent(clearcookies);
    intentClearCookies.setTitle(R.string.ClearCookies);
    intentClearCookies.setEnabled(true);
    launchPrefCat.addPreference(intentClearCookies);

And then Create Activity Class somewhat like below, As different people as different approach you can use any approach you like this is just an example.

public class ClearCookies extends Activity {


@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);

    showDialog();
}

/**

private void showDialog() throws NotFoundException {
    new AlertDialog.Builder(this)
            .setTitle(getResources().getString(R.string.ClearCookies))
            .setMessage(
                    getResources().getString(R.string.ClearCookieQuestion))
            .setIcon(
                    getResources().getDrawable(
                            android.R.drawable.ic_dialog_alert))
            .setPositiveButton(
                    getResources().getString(R.string.PostiveYesButton),
                    new DialogInterface.OnClickListener() {

                        @Override
                        public void onClick(DialogInterface dialog,
                                int which) {
                            //Do Something Here

                        }
                    })
            .setNegativeButton(
                    getResources().getString(R.string.NegativeNoButton),
                    new DialogInterface.OnClickListener() {

                        @Override
                        public void onClick(DialogInterface dialog,
                                int which) {
                            //Do Something Here
                        }
                    }).show();
}}

As told before there are number of ways doing this. this is one of the way you can do your task, please accept the answer if you feel that you have got it what you wanted.

I had the same problem on Visual Studio 2010 on C++ and I surpassed it by Tools -> Options -> Text Editor -> C/C++ -> Advanced -> Disable database -> False, Ok ; Close VS; open VS and voila.

You can try calling this method in you program:

static double string_double(string s)
    {
        double temp = 0;
        double dtemp = 0;
        int b = 0;
        for (int i = 0; i < s.Length; i++)
        {
            if (s[i] == '.')
            {
                i++;
                while (i < s.Length)
                {
                    dtemp = (dtemp * 10) + (int)char.GetNumericValue(s[i]);
                    i++;
                    b++;
                }
                temp = temp + (dtemp * Math.Pow(10, -b));
                return temp;
            }
            else
            {
                temp = (temp * 10) + (int)char.GetNumericValue(s[i]);
            }
        }
        return -1; //if somehow failed
    }

Example:

string s = "12.3";
double d = string_double (s);        //d = 12.3 

Placing @Transient on getter with private field worked for me.

private String name;

    @Transient
    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

As @Jthorpe alluded to, ComponentClass only allows either Component or PureComponent but not a FunctionComponent.

If you attempt to pass a FunctionComponent, typescript will throw an error similar to...

Type '(props: myProps) => Element' provides no match for the signature 'new (props: myProps, context?: any): Component<myProps, any, any>'.

However, by using ComponentType rather than ComponentClass you allow for both cases. Per the react declaration file the type is defined as...

type ComponentType<P = {}> = ComponentClass<P, any> | FunctionComponent<P>

A Date object's underlying value is actually in UTC. To prove this, notice that if you type new Date(0) you'll see something like: Wed Dec 31 1969 16:00:00 GMT-0800 (PST). 0 is treated as 0 in GMT, but .toString() method shows the local time.

Big note, UTC stands for Universal time code. The current time right now in 2 different places is the same UTC, but the output can be formatted differently.

What we need here is some formatting

var _date = new Date(1270544790922); 
// outputs > "Tue Apr 06 2010 02:06:30 GMT-0700 (PDT)", for me
_date.toLocaleString('fi-FI', { timeZone: 'Europe/Helsinki' });
// outputs > "6.4.2010 klo 12.06.30"
_date.toLocaleString('en-US', { timeZone: 'Europe/Helsinki' });
// outputs > "4/6/2010, 12:06:30 PM"

This works but.... you can't really use any of the other date methods for your purposes since they describe the user's timezone. What you want is a date object that's related to the Helsinki timezone. Your options at this point are to use some 3rd party library (I recommend this), or hack-up the date object so you can use most of it's methods.

Option 1 - a 3rd party like moment-timezone

moment(1270544790922).tz('Europe/Helsinki').format('YYYY-MM-DD HH:mm:ss')
// outputs > 2010-04-06 12:06:30
moment(1270544790922).tz('Europe/Helsinki').hour()
// outputs > 12

This looks a lot more elegant than what we're about to do next.

Option 2 - Hack up the date object

var currentHelsinkiHoursOffset = 2; // sometimes it is 3
var date = new Date(1270544790922);
var helsenkiOffset = currentHelsinkiHoursOffset*60*60000;
var userOffset = _date.getTimezoneOffset()*60000; // [min*60000 = ms]
var helsenkiTime = new Date(date.getTime()+ helsenkiOffset + userOffset);
// Outputs > Tue Apr 06 2010 12:06:30 GMT-0700 (PDT)

It still thinks it's GMT-0700 (PDT), but if you don't stare too hard you may be able to mistake that for a date object that's useful for your purposes.

I conveniently skipped a part. You need to be able to define currentHelsinkiOffset. If you can use date.getTimezoneOffset() on the server side, or just use some if statements to describe when the time zone changes will occur, that should solve your problem.

Conclusion - I think especially for this purpose you should use a date library like moment-timezone.

When I open a "DOS" command prompt, I use a batch file which sets all of the options I need and adds my old-time dos utilities to the path too.

@set path=%path%;c:\utils
@doskey cd=cd/d $*
@cd \wip
@cmd.exe

The doskey line sets the CD command so that it will do both drive and folder simultaneously. If this doesn't work, it is possibly because of the version of windows that you're running.

To clear the whole thing use the reset_session method in a controller.

reset_session

Here's the documentation on this method: http://api.rubyonrails.org/classes/ActionController/Base.html#M000668

Resets the session by clearing out all the objects stored within and initializing a new session object.

Good luck!

Once you have IIS Express installed (the easiest way is through Microsoft Web Platform Installer), you will find the executable file in %PROGRAMFILES%\IIS Express (%PROGRAMFILES(x86)%\IIS Express on x64 architectures) and its called iisexpress.exe.

To see all the possible command-line options, just run:

iisexpress /?

and the program detailed help will show up.

If executed without parameters, all the sites defined in the configuration file and marked to run at startup will be launched. An icon in the system tray will show which sites are running.

There are a couple of useful options once you have some sites created in the configuration file (found in %USERPROFILE%\Documents\IISExpress\config\applicationhost.config): the /site and /siteId.

With the first one, you can launch a specific site by name:

iisexpress /site:SiteName

And with the latter, you can launch by specifying the ID:

iisexpress /siteId:SiteId

With this, if IISExpress is launched from the command-line, a list of all the requests made to the server will be shown, which can be quite useful when debugging.

Finally, a site can be launched by specifying the full directory path. IIS Express will create a virtual configuration file and launch the site (remember to quote the path if it contains spaces):

iisexpress /path:FullSitePath

This covers the basic IISExpress usage from the command line.

SELECT
   *
FROM
   primarytable P
WHERE
   NOT EXISTS (SELECT * FROM secondarytable S
     WHERE
         P.PKCol = S.FKCol)

Generally, (NOT) EXISTS is a better choice then (NOT) IN or (LEFT) JOIN

Well, data.str().c_str() yields a char const* but your function Printfunc() wants to have char*s. Based on the name, it doesn't change the arguments but merely prints them and/or uses them to name a file, in which case you should probably fix your declaration to be

void Printfunc(int a, char const* loc, char const* stream)

The alternative might be to turn the char const* into a char* but fixing the declaration is preferable:

Printfunc(num, addr, const_cast<char*>(data.str().c_str()));

You don't need to create a new datafile; you can extend your existing tablespace data files.

Execute the following to determine the filename for the existing tablespace:

  SELECT * FROM DBA_DATA_FILES;

Then extend the size of the datafile as follows (replace the filename with the one from the previous query):

  ALTER DATABASE DATAFILE 'D:\ORACLEXE\ORADATA\XE\SYSTEM.DBF' RESIZE 2048M; 

[Update]

While the solution under "old answer" will work for general problems, this section is to answer your specific question after clarification from your comment.

You should be able to set environment variables exactly like you specify in your question. As an example, I have a Heroku app that uses HTTP basic authentication.

# app/controllers/application_controller.rb
class ApplicationController < ActionController::Base
  protect_from_forgery
  before_filter :authenticate

  def authenticate
    authenticate_or_request_with_http_basic do |username, password|
      username == ENV['HTTP_USER'] && password == ENV['HTTP_PASS']
    end
  end
end

# config/initializers/dev_environment.rb
unless Rails.env.production?
  ENV['HTTP_USER'] = 'testuser'
  ENV['HTTP_PASS'] = 'testpass'
end

So in your case you would use

unless Rails.env.production?
  ENV['admin_password'] = "secret"
end

Don't forget to restart the server so the configuration is reloaded!

[Old Answer]

For app-wide configuration, you might consider a solution like the following:

Create a file config/application.yml with a hash of options you want to be able to access:

admin_password: something_secret
allow_registration: true
facebook:
  app_id: application_id_here
  app_secret: application_secret_here
  api_key: api_key_here

Now, create the file config/initializers/app_config.rb and include the following:

require 'yaml'

yaml_data = YAML::load(ERB.new(IO.read(File.join(Rails.root, 'config', 'application.yml'))).result)
APP_CONFIG = HashWithIndifferentAccess.new(yaml_data)

Now, anywhere in your application, you can access APP_CONFIG[:admin_password], along with all your other data. (Note that since the initializer includes ERB.new, your YAML file can contain ERB markup.)

Try updating the line to:

ocr.Init(@"C:\", "eng", false); // the path here should be the parent folder of tessdata

1. Find the path from error log and open the file in explorer 2)select the file and right-click -> properties
2. Then check the 'unblock' option and click on apply

Pandas Sorting 101

sort has been replaced in v0.20 by DataFrame.sort_values and DataFrame.sort_index. Aside from this, we also have argsort.

Here are some common use cases in sorting, and how to solve them using the sorting functions in the current API. First, the setup.

# Setup
np.random.seed(0)
df = pd.DataFrame({'A': list('accab'), 'B': np.random.choice(10, 5)})    
df                                                                                                                                        
   A  B
0  a  7
1  c  9
2  c  3
3  a  5
4  b  2

Sort by Single Column

For example, to sort df by column "A", use sort_values with a single column name:

df.sort_values(by='A')

   A  B
0  a  7
3  a  5
4  b  2
1  c  9
2  c  3

If you need a fresh RangeIndex, use DataFrame.reset_index.

Sort by Multiple Columns

For example, to sort by both col "A" and "B" in df, you can pass a list to sort_values:

df.sort_values(by=['A', 'B'])

   A  B
3  a  5
0  a  7
4  b  2
2  c  3
1  c  9

Sort By DataFrame Index

df2 = df.sample(frac=1)
df2

   A  B
1  c  9
0  a  7
2  c  3
3  a  5
4  b  2

You can do this using sort_index:

df2.sort_index()

   A  B
0  a  7
1  c  9
2  c  3
3  a  5
4  b  2

df.equals(df2)                                                                                                                            
# False
df.equals(df2.sort_index())                                                                                                               
# True

Here are some comparable methods with their performance:

%timeit df2.sort_index()                                                                                                                  
%timeit df2.iloc[df2.index.argsort()]                                                                                                     
%timeit df2.reindex(np.sort(df2.index))                                                                                                   

605 µs ± 13.6 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)
610 µs ± 24.2 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)
581 µs ± 7.63 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)

Sort by List of Indices

For example,

idx = df2.index.argsort()
idx
# array([0, 7, 2, 3, 9, 4, 5, 6, 8, 1])

This "sorting" problem is actually a simple indexing problem. Just passing integer labels to iloc will do.

df.iloc[idx]

   A  B
1  c  9
0  a  7
2  c  3
3  a  5
4  b  2

I read a csv file from local directory. Following code works for me.

# to get number of which contains na
sum(is.na(df[, c(columnName)]) # to get number of na row

# to get number of which not contains na
sum(!is.na(df[, c(columnName)]) 

#here columnName is your desire column name

In most of the responses to this issue, there's one critical aspect being overlooked that was brought up by the original asker. The app needs to be installed without deleting the existing install. In my case, the app uses an SQLite database that stores quite a bit of data for the user. Obviously, if you delete the app, then you delete the data. A solution that allowed me to test it in the same way a user will update it was a must.

In my case, the issue was Xcode using a provisioning profile automatically generated by Xcode. This probably happened because I got a new computer and didn't transfer the distribution provisioning profile over. Not to mention, I had not updated the app in almost 2 years. So my original provisioning profile (which contains the Entitlements application-identifier) was long gone. Solution: in Xcode preferences-> Accounts-> Select the appropriate Apple ID-> View Details-> Under Provisioning Profiles, right-click on the Xcode-generated profile for that app (it's prefixed with XC iOS), and select Move to Trash.

On the developer website, create a new distribution profile with your App's ID. Download the new profile, double click and Xcode should automatically install it. Conversely, you could return to the profiles listed in Xcode and tap the Download button next to your newly created profile. Build the app and try running again. By the way, my Xcode is set to automatically manage code signing, which other than this issue works great.

The simplest way to create signed/unsigned APKs using Eclipse and ADT is as follows:

1. Right click your project in the "Project Explorer"
2. Hover over "Android Tools"
3. Select either "Export Signed Application Package" or "Export Unsigned Application Package"

4. Select the location for the new APK file and click "Save".

   • NOTE: If you're trying to build a APK for beta distribution, you'll probably need to create a signed package, which requires a keystore. If you follow the "Signed Application" process in Eclipse ADT it will guide you through the process of creating a new keystore.

Hope this helps.

Go to Environment variable and add

JAVA_HOME=C:\Program Files (x86)\Java\jdk1.6.0_37

till jdk path (exclude bin folder)
now set JAVA_HOME into path as PATH=%JAVA_HOME%\bin;
This will set java path to all the applications which are using java.

For ANT use,

ANT_HOME=C:\Program Files (x86)\apache-ant-1.8.2\bin;

and include ANT_HOME into PATH, so path will look like PATH=%JAVA_HOME%\bin;%ANT_HOME%;

I used the above command line as follow: update TABLE-NAME set FIELD = replace(FIELD, 'And', 'and'); the purpose was to replace And with and ("A" should be lowercase). The problem is it cannot find the "And" in database, but if I use like "%And%" then it can find it along with many other ands that are part of a word or even the ones that are already lowercase.

For this format (supposed datepart has the format dd-mm-yyyy) in plain javascript:

var dt  = '01-01-1970 00:03:44'.split(/\-|\s/)_x000D_
    dat = new Date(dt.slice(0,3).reverse().join('/')+' '+dt[3]);

Just found this online at http://snipplr.com/view/62238/get-youtube-video-id-very-robust/

function getYouTubeId($url) {
// Format all domains to http://domain for easier URL parsing
str_replace('https://', 'http://', $url);
if (!stristr($url, 'http://') && (strlen($url) != 11)) {
    $url = 'http://' . $url;
}
$url = str_replace('http://www.', 'http://', $url);

if (strlen($url) == 11) {
    $code = $url;
} else if (preg_match('/http:\/\/youtu.be/', $url)) {
    $url = parse_url($url, PHP_URL_PATH);
    $code = substr($url, 1, 11);
} else if (preg_match('/watch/', $url)) {
    $arr = parse_url($url);
    parse_str($url);
    $code = isset($v) ? substr($v, 0, 11) : false;
} else if (preg_match('/http:\/\/youtube.com\/v/', $url)) {
    $url = parse_url($url, PHP_URL_PATH);
    $code = substr($url, 3, 11);
} else if (preg_match('/http:\/\/youtube.com\/embed/', $url, $matches)) {
    $url = parse_url($url, PHP_URL_PATH);
    $code = substr($url, 7, 11);
} else if (preg_match("#(?<=v=)[a-zA-Z0-9-]+(?=&)|(?<=[0-9]/)[^&\n]+|(?<=v=)[^&\n]+#", $url, $matches) ) {
    $code = substr($matches[0], 0, 11);
} else {
    $code = false;
}

if ($code && (strlen($code) < 11)) {
    $code = false;
}

return $code;
}

Instead of setting absolute widths and heights, you can use percentages:

#mydiv img {
    height: 100%;
    width: 100%;
}

The problem may where the code is being executed. If you are in the head of a document executing JavaScript, even when you have an element with id="u" in your web page, the code gets executed before the DOM is finished loading, and so none of the HTML really exists yet... You can fix this by moving your code to the end of the page just above the closing html tag. This is one good reason to use jQuery.

User JQuery is EmptyObject to check whether array is contains elements or not.

var testArray=[1,2,3,4,5];
var testArray1=[];
console.log(jQuery.isEmptyObject(testArray)); //false
console.log(jQuery.isEmptyObject(testArray1)); //true

I had to do it using XML, put the following in a Content Editor Web Part by adding a Content Editor Web Part, Edit the Web Part, then click the Edit Source button and paste in this:

<input type="button" onclick="GetUserInfo()" value="Show Domain, Username and Email"/> 

<script type="text/javascript">
function GetUserInfo() {

$.ajax({
    type: "GET",
    url: "https://<ENTER YOUR DOMAIN HERE>/_api/web/currentuser",
    dataType: "xml",

    error: function (e) {
        alert("An error occurred while processing XML file" + e.toString());
        console.log("XML reading Failed: ", e);
    },

    success: function (response) {
        var content = $(response).find("content");
        var spsEmail = content.find("d\\:Email").text();
        var rawLoginName = content.find("d\\:LoginName").text();
        var spsDomainUser = rawLoginName.slice(rawLoginName.indexOf('|') + 1);
        var indexOfSlash =  spsDomainUser.indexOf('\\') + 1;
        var spsDomain = spsDomainUser.slice(0, indexOfSlash - 1);
        var spsUser = spsDomainUser.slice(indexOfSlash);
        alert("Domain: "  + spsDomain + " User: " + spsUser + " Email: " + spsEmail);
    }
});
}

</script>

Check the following link to see if your data is XML or JSON:

https://<Your_Sharepoint_Domain>/_api/web/currentuser

In the accepted answer Kate uses this method:

var userid= _spPageContextInfo.userId;
var requestUri = _spPageContextInfo.webAbsoluteUrl + "/_api/web/getuserbyid(" + userid + ")

Editing the hosts file is less of a pain when you run "ipconfig /flushdns" from the windows command prompt, instead of restarting your computer.

As already mentioned, tern.js is a new and promising project with plugins for Sublime Text, Vim and Emacs. I´ve been using TernJS for Sublime for a while and the suggestions I get are way better than the standard ones:

Tern scans all .js files in your project. You can get support for DOM, nodejs, jQuery, and more by adding "libs" in your .sublime-project file:

"ternjs": {
    "exclude": ["wordpress/**", "node_modules/**"],
    "libs": ["browser", "jquery"],
    "plugins": {
        "requirejs": {
            "baseURL": "./js"
        }
    }
}

My personal fav PrettyC wantabe is uncrustify: http://uncrustify.sourceforge.net/. It's got a few billion options however so I also suggest you download UniversalIndentGUI_macx, (also on sourceforge) a GUI someone wrote to help set the options the way you like them.

You can then add this custom user script to uncrustify the selected text:

#! /bin/sh
#
# uncrustify!
echo -n "%%%{PBXSelection}%%%"
/usr/local/bin/uncrustify -q -c /usr/local/share/uncrustify/geo_uncrustify.cfg -l oc+ <&0
echo -n "%%%{PBXSelection}%%%"

In JupyterNotebook cell, Simply you can use:

%%html
<style type='text/css'>
.CodeMirror{
font-size: 17px;
</style>

GROUP BY YEAR(record_date), MONTH(record_date)

Check out the date and time functions in MySQL.

You have to workaround this via static application context accessor approach:

@Component
public class StaticContextAccessor {

    private static StaticContextAccessor instance;

    @Autowired
    private ApplicationContext applicationContext;

    @PostConstruct
    public void registerInstance() {
        instance = this;
    }

    public static <T> T getBean(Class<T> clazz) {
        return instance.applicationContext.getBean(clazz);
    }

}

Then you can access bean instances in a static manner.

public class Boo {

    public static void randomMethod() {
         StaticContextAccessor.getBean(Foo.class).doStuff();
    }

}

This question is vague, but if you want to make the image with Javascript. It is simple.

function loadImages(src) {
  if (document.images) {
    img1 = new Image();
    img1.src = src;
}
loadImages("image.jpg");

The image will be requested but until you show it it will never be displayed. great for pre loading images you expect to be requests but delaying it until the document is loaded.

Example

Static Memory Allocation:

• Variables get allocated permanently
• Allocation is done before program execution
• It uses the data structure called stack for implementing static allocation
• Less efficient
• There is no memory reusability

Dynamic Memory Allocation:

• Variables get allocated only if the program unit gets active
• Allocation is done during program execution
• It uses the data structure called heap for implementing dynamic allocation
• More efficient
• There is memory reusability . Memory can be freed when not required

The dplyr hybridized options are now around 30% faster than the Base R subset reassigns. On a 100M datapoint dataframe mutate_all(~replace(., is.na(.), 0)) runs a half a second faster than the base R d[is.na(d)] <- 0 option. What one wants to avoid specifically is using an ifelse() or an if_else(). (The complete 600 trial analysis ran to over 4.5 hours mostly due to including these approaches.) Please see benchmark analyses below for the complete results.

If you are struggling with massive dataframes, data.table is the fastest option of all: 40% faster than the standard Base R approach. It also modifies the data in place, effectively allowing you to work with nearly twice as much of the data at once.

A clustering of other helpful tidyverse replacement approaches

Locationally:

• index mutate_at(c(5:10), ~replace(., is.na(.), 0))
• direct reference mutate_at(vars(var5:var10), ~replace(., is.na(.), 0))
• fixed match mutate_at(vars(contains("1")), ~replace(., is.na(.), 0))
  • or in place of contains(), try ends_with(),starts_with()
• pattern match mutate_at(vars(matches("\\d{2}")), ~replace(., is.na(.), 0))

Conditionally:
(change just single type and leave other types alone.)

• integers mutate_if(is.integer, ~replace(., is.na(.), 0))
• numbers mutate_if(is.numeric, ~replace(., is.na(.), 0))
• strings mutate_if(is.character, ~replace(., is.na(.), 0))

The Complete Analysis -

Updated for dplyr 0.8.0: functions use purrr format ~ symbols: replacing deprecated funs() arguments.

Approaches tested:

# Base R: 
baseR.sbst.rssgn   <- function(x) { x[is.na(x)] <- 0; x }
baseR.replace      <- function(x) { replace(x, is.na(x), 0) }
baseR.for          <- function(x) { for(j in 1:ncol(x))
    x[[j]][is.na(x[[j]])] = 0 }

# tidyverse
## dplyr
dplyr_if_else      <- function(x) { mutate_all(x, ~if_else(is.na(.), 0, .)) }
dplyr_coalesce     <- function(x) { mutate_all(x, ~coalesce(., 0)) }

## tidyr

A note on the other high performers

When the datasets get larger, Tidyr''s replace_na had historically pulled out in front. With the current collection of 100M data points to run through, it performs almost exactly as well as a Base R For Loop. I am curious to see what happens for different sized dataframes.

Additional examples for the mutate and summarize _at and _all function variants can be found here: https://rdrr.io/cran/dplyr/man/summarise_all.html Additionally, I found helpful demonstrations and collections of examples here: https://blog.exploratory.io/dplyr-0-5-is-awesome-heres-why-be095fd4eb8a

Works for jekyll or more specifically kramdown, which is a superset of markdown, as part of Jekyll's (default) configuration. But not for plain markdown. ^_^

That's a very general question. One answer is: "it depends what kind of UUID you wish to generate". But a better one is this: "Well, before I answer, can you tell us why you need to code up your own UUID generation algorithm instead of calling the UUID generation functionality that most modern operating systems provide?"

Doing that is easier and safer, and since you probably don't need to generate your own, why bother coding up an implementation? In that case, the answer becomes use whatever your O/S, programming language or framework provides. For example, in Windows, there is CoCreateGuid or UuidCreate or one of the various wrappers available from the numerous frameworks in use. In Linux there is uuid_generate.

If you, for some reason, absolutely need to generate your own, then at least have the good sense to stay away from generating v1 and v2 UUIDs. It's tricky to get those right. Stick, instead, to v3, v4 or v5 UUIDs.

Update: In a comment, you mention that you are using Python and link to this. Looking through the interface provided, the easiest option for you would be to generate a v4 UUID (that is, one created from random data) by calling uuid.uuid4().

If you have some data that you need to (or can) hash to generate a UUID from, then you can use either v3 (which relies on MD5) or v5 (which relies on SHA1). Generating a v3 or v5 UUID is simple: first pick the UUID type you want to generate (you should probably choose v5) and then pick the appropriate namespace and call the function with the data you want to use to generate the UUID from. For example, if you are hashing a URL you would use NAMESPACE_URL:

uuid.uuid3(uuid.NAMESPACE_URL, 'https://ripple.com')

Please note that this UUID will be different than the v5 UUID for the same URL, which is generated like this:

uuid.uuid5(uuid.NAMESPACE_URL, 'https://ripple.com')

A nice property of v3 and v5 URLs is that they should be interoperable between implementations. In other words, if two different systems are using an implementation that complies with RFC4122, they will (or at least should) both generate the same UUID if all other things are equal (i.e. generating the same version UUID, with the same namespace and the same data). This property can be very helpful in some situations (especially in content-addressible storage scenarios), but perhaps not in your particular case.

To check for assignability, you can use the Type.IsAssignableFrom method:

typeof(SomeType).IsAssignableFrom(typeof(Derived))

This will work as you expect for type-equality, inheritance-relationships and interface-implementations but not when you are looking for 'assignability' across explicit / implicit conversion operators.

To check for strict inheritance, you can use Type.IsSubclassOf:

typeof(Derived).IsSubclassOf(typeof(SomeType))

you can use

<a href="\\computername\folder">Open folder</a>

in Internet Explorer

You can't remove an element from the basic Java array. Take a look at various Collections and ArrayList instead.

I understand using a global variable is sometimes the most convenient thing to do, especially in cases where usage of class makes the easiest thing so much harder (e.g., multiprocessing). I ran into the same problem with declaring global variables and figured it out with some experiments.

The reason that g_c was not changed by the run function within your class is that the referencing to the global name within g_c was not established precisely within the function. The way Python handles global declaration is in fact quite tricky. The command global g_c has two effects:

1. Preconditions the entrance of the key "g_c" into the dictionary accessible by the built-in function, globals(). However, the key will not appear in the dictionary until after a value is assigned to it.

2. (Potentially) alters the way Python looks for the variable g_c within the current method.

The full understanding of (2) is particularly complex. First of all, it only potentially alters, because if no assignment to the name g_c occurs within the method, then Python defaults to searching for it among the globals(). This is actually a fairly common thing, as is the case of referencing within a method modules that are imported all the way at the beginning of the code.

However, if an assignment command occurs anywhere within the method, Python defaults to finding the name g_c within local variables. This is true even when a referencing occurs before an actual assignment, which will lead to the classic error:

UnboundLocalError: local variable 'g_c' referenced before assignment

Now, if the declaration global g_c occurs anywhere within the method, even after any referencing or assignment, then Python defaults to finding the name g_c within global variables. However, if you are feeling experimentative and place the declaration after a reference, you will be rewarded with a warning:

SyntaxWarning: name 'g_c' is used prior to global declaration

If you think about it, the way the global declaration works in Python is clearly woven into and consistent with how Python normally works. It's just when you actually want a global variable to work, the norm becomes annoying.

Here is a code that summarizes what I just said (with a few more observations):

g_c = 0
print ("Initial value of g_c: " + str(g_c))
print("Variable defined outside of method automatically global? "
      + str("g_c" in globals()))

class TestClass():
    def direct_print(self):
        print("Directly printing g_c without declaration or modification: "
              + str(g_c))
        #Without any local reference to the name
        #Python defaults to search for the variable in globals()
        #This of course happens for all the module names you import

    def mod_without_dec(self):
        g_c = 1
        #A local assignment without declaring reference to global variable
        #makes Python default to access local name
        print ("After mod_without_dec, local g_c=" + str(g_c))
        print ("After mod_without_dec, global g_c=" + str(globals()["g_c"]))


    def mod_with_late_dec(self):
        g_c = 2
        #Even with a late declaration, the global variable is accessed
        #However, a syntax warning will be issued
        global g_c
        print ("After mod_with_late_dec, local g_c=" + str(g_c))
        print ("After mod_with_late_dec, global g_c=" + str(globals()["g_c"]))

    def mod_without_dec_error(self):
        try:
            print("This is g_c" + str(g_c))
        except:
            print("Error occured while accessing g_c")
            #If you try to access g_c without declaring it global
            #but within the method you also alter it at some point
            #then Python will not search for the name in globals()
            #!!!!!Even if the assignment command occurs later!!!!!
        g_c = 3

    def sound_practice(self):
        global g_c
        #With correct declaration within the method
        #The local name g_c becomes an alias for globals()["g_c"]
        g_c = 4
        print("In sound_practice, the name g_c points to: " + str(g_c))

Visual Studio Code v1.35.0 let's you set the (Ctrl+Tab) / (Shift+Ctrl+Tab) key sequences to sequentially switch between editors by binding those keys sequences to the commands "View: Open Next Editor" and "View: Open Previous Editor", respectively.

On macOS:

1. Navigate to: Code > Preferences > Keyboard Shortcuts
2. Search or navigate down to the following two options:
   • View: Open Next Editor
   • View: Open Previous Editor
3. Change both keybindings to the desired key sequence.
   • View: Open Next Editor -> (Ctrl+Tab)
   • View: Open Previous Editor -> (Shift+Ctrl+Tab)
4. You will likely run into a conflicting binding. If so, take note of the command and reassign or remove the existing key binding.

If you mess up, you can always revert back to the default state for a given binding by right-clicking on any keybinding and selecting "Reset Keybinding".

To disable the errors windows related with certificates you can start Chrome from console and use this option: --ignore-certificate-errors.

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

You should use it for testing purposes. A more complete list of options is here: http://peter.sh/experiments/chromium-command-line-switches/

Mark, this is already answered in your previous topic. But OK, here it is again:

Suppose ${list} points to a List<Object>, then the following

<c:forEach items="${list}" var="item">
    ${item}<br>
</c:forEach>

does basically the same as as following in "normal Java":

for (Object item : list) {
    System.out.println(item);
}

If you have a List<Map<K, V>> instead, then the following

<c:forEach items="${list}" var="map">
    <c:forEach items="${map}" var="entry">
        ${entry.key}<br>
        ${entry.value}<br>
    </c:forEach>
</c:forEach>

does basically the same as as following in "normal Java":

for (Map<K, V> map : list) {
    for (Entry<K, V> entry : map.entrySet()) {
        System.out.println(entry.getKey());
        System.out.println(entry.getValue());
    }
}

The key and value are here not special methods or so. They are actually getter methods of Map.Entry object (click at the blue Map.Entry link to see the API doc). In EL (Expression Language) you can use the . dot operator to access getter methods using "property name" (the getter method name without the get prefix), all just according the Javabean specification.

That said, you really need to cleanup the "answers" in your previous topic as they adds noise to the question. Also read the comments I posted in your "answers".
