I use this and it works right

@Id
@GeneratedValue(generator = "SEC_ODON", strategy = GenerationType.SEQUENCE)
@SequenceGenerator(name = "SEC_ODON", sequenceName = "SO.SEC_ODON",allocationSize=1)
@Column(name="ID_ODON", unique=true, nullable=false, precision=10, scale=0)
public Long getIdOdon() {
    return this.idOdon;
}

via Jquery filter() method:

http://jsfiddle.net/9n4e1agn/1/

HTML:

<button   data-id='1'>One</button>
<button   data-id='2'>Two</button>

JavaScript:

$(function() {    
    $('button').filter(function(){
        return $(this).data("id")   == 2}).css({background:'red'});  
     });

You must have a server-side script to handle your request, it can't be done using javascript.

To send raw data without URIencoding or escaping special characters to the php and save it as new txt file you can send ajax request using post method and FormData like:

JS:

var data = new FormData();
data.append("data" , "the_text_you_want_to_save");
var xhr = (window.XMLHttpRequest) ? new XMLHttpRequest() : new activeXObject("Microsoft.XMLHTTP");
xhr.open( 'post', '/path/to/php', true );
xhr.send(data);

PHP:

if(!empty($_POST['data'])){
$data = $_POST['data'];
$fname = mktime() . ".txt";//generates random name

$file = fopen("upload/" .$fname, 'w');//creates new file
fwrite($file, $data);
fclose($file);
}

Edit:

As Florian mentioned below, the XHR fallback is not required since FormData is not supported in older browsers (formdata browser compatibiltiy), so you can declare XHR variable as:

var xhr = new XMLHttpRequest();

Also please note that this works only for browsers that support FormData such as IE +10.

Try using the which and/or button property

The demo

function onClick(e) {
    if (!e)
    {
        return;
    }

    switch(`${e.which}${e.button}`)
    {
        case '10':
            console.log('Left mouse button at ' + e.clientX + 'x' + e.clientY);
        break;
        case '21':
            console.log('Middle mouse button ' + e.clientX + 'x' + e.clientY);
        break;
        case '32':
            console.log('Right mouse button ' + e.clientX + 'x' + e.clientY);
        break;
        case '43':
            console.log('Backward mouse button ' + e.clientX + 'x' + e.clientY);
        break;
        case '54':
            console.log('Forward mouse button ' + e.clientX + 'x' + e.clientY);
        break;
    }
}

window.addEventListener("mousedown", onClick);

MacOS

On Windows and Linux there are modifier keys Alt, Shift and Ctrl. On Mac there’s one more: Cmd, corresponding to the property metaKey...
Even if we’d like to force Mac users to Ctrl+click – that’s kind of difficult. The problem is: a left-click with Ctrl is interpreted as a right-click on MacOS, and it generates the contextmenu event, not click like Windows/Linux.
So if we want users of all operating systems to feel comfortable, then together with ctrlKey we should check metaKey.
For JS-code it means that we should check if (event.ctrlKey || event.metaKey)...

For something simple, you can combine ls with sort. For just a list of file names:
ls -1 | sort

To sort them in reverse order:
ls -1 | sort -r

<input type="number" step="1" ...

By adding the step attribute, you restrict input to integers.

Of course you should always validate on the server as well. Except under carefully controlled conditions, everything received from a client needs to be treated as suspect.

Yes - older POSIX standards defined usleep(), so this is available on Linux:

int usleep(useconds_t usec);

DESCRIPTION

The usleep() function suspends execution of the calling thread for (at least) usec microseconds. The sleep may be lengthened slightly by any system activity or by the time spent processing the call or by the granularity of system timers.

usleep() takes microseconds, so you will have to multiply the input by 1000 in order to sleep in milliseconds.

usleep() has since been deprecated and subsequently removed from POSIX; for new code, nanosleep() is preferred:

#include <time.h>

int nanosleep(const struct timespec *req, struct timespec *rem);

DESCRIPTION

nanosleep() suspends the execution of the calling thread until either at least the time specified in *req has elapsed, or the delivery of a signal that triggers the invocation of a handler in the calling thread or that terminates the process.

The structure timespec is used to specify intervals of time with nanosecond precision. It is defined as follows:

struct timespec {
    time_t tv_sec;        /* seconds */
    long   tv_nsec;       /* nanoseconds */
};

An example msleep() function implemented using nanosleep(), continuing the sleep if it is interrupted by a signal:

#include <time.h>
#include <errno.h>    

/* msleep(): Sleep for the requested number of milliseconds. */
int msleep(long msec)
{
    struct timespec ts;
    int res;

    if (msec < 0)
    {
        errno = EINVAL;
        return -1;
    }

    ts.tv_sec = msec / 1000;
    ts.tv_nsec = (msec % 1000) * 1000000;

    do {
        res = nanosleep(&ts, &ts);
    } while (res && errno == EINTR);

    return res;
}

While jball's answer is an excellent description of content insets, it doesn't answer the question of when to use it. I'll borrow from his diagrams:

  _|?_cW_?_|_?_
   |       | 
---------------
   |content| ?
 ? |content| contentInset.top
cH |content|
 ? |content| contentInset.bottom
   |content| ?
---------------
   |content|    
-------------?-

That's what you get when you do it, but the usefulness of it only shows when you scroll:

  _|?_cW_?_|_?_
   |content| ? content is still visible
---------------
   |content| ?
 ? |content| contentInset.top
cH |content|
 ? |content| contentInset.bottom
   |content| ?
---------------
  _|_______|___ 
             ?

That top row of content will still be visible because it's still inside the frame of the scroll view. One way to think of the top offset is "how much to shift the content down the scroll view when we're scrolled all the way to the top"

To see a place where this is actually used, look at the build-in Photos app on the iphone. The Navigation bar and status bar are transparent, and the contents of the scroll view are visible underneath. That's because the scroll view's frame extends out that far. But if it wasn't for the content inset, you would never be able to have the top of the content clear that transparent navigation bar when you go all the way to the top.

Below function can be used to check for a value in any level in a JSON

function _isContains(json, value) {
    let contains = false;
    Object.keys(json).some(key => {
        contains = typeof json[key] === 'object' ? _isContains(json[key], value) : json[key] === value;
         return contains;
    });
    return contains;
 }

then to check if JSON contains the value

_isContains(JSONObject, "dog")

See this fiddle: https://jsfiddle.net/ponmudi/uykaacLw/

Most of the answers mentioned here compares by 'name' key. But no need to care about the key, can just checks if JSON contains the given value. So that the function can be used to find any value irrespective of the key.

You could use document.write.

Without jQuery

<!DOCTYPE html>
<html>
<head><meta charset=utf-8></head>
<body onload="document.write('<!doctype html><html><head><meta charset=utf-8></head><body><p>You cannot find this in the page source. (Your page needs to be in this document.write argument.)</p></body></html>');">
</body></html>

Or with jQuery

$(function () {
  document.write("<!doctype html><html><head><meta charset=utf-8></head><body><p>You cannot find this in the page source. (Your page needs to be in this document.write argument.)</p></body></html>")
});

Jar class/package is for specific Jar file mechanisms where there is a manifest that is used by the Jar files in some cases.

The Zip file class/package handles any compressed files that include Jar files, which is a type of compressed file.

The Jar classes thus extend the Zip package classes.

Here is the right way to do imports in Java.

import Dan.Vik;
class Kab
{
public static void main(String args[])
{
    Vik Sam = new Vik();
    Sam.disp();
}
}

You don't import methods in java. There is an advanced usage of static imports but basically you just import packages and classes. If the function you are importing is a static function you can do a static import, but I don't think you are looking for static imports here.

yes it is possible you can use border-radius CSS property. For more info have a look at http://zeeshanmkhan.com/post/2/css-rounded-corner-gradient-drop-shadow-and-opacity

You should use & / | operators and be careful about operator precedence (== has lower precedence than bitwise AND and OR):

df1 = sqlContext.createDataFrame(
    [(1, "a", 2.0), (2, "b", 3.0), (3, "c", 3.0)],
    ("x1", "x2", "x3"))

df2 = sqlContext.createDataFrame(
    [(1, "f", -1.0), (2, "b", 0.0)], ("x1", "x2", "x3"))

df = df1.join(df2, (df1.x1 == df2.x1) & (df1.x2 == df2.x2))
df.show()

## +---+---+---+---+---+---+
## | x1| x2| x3| x1| x2| x3|
## +---+---+---+---+---+---+
## |  2|  b|3.0|  2|  b|0.0|
## +---+---+---+---+---+---+

I use @gnarf's method, though I fall back on document.writelning a <script> tag for IE<7 as I couldn't get DOM creation to work reliably in IE6 (and TBH didn't care enough to put much effort into it). The core of my code is:

if (horus.script.broken) {
    document.writeln('<script type="text/javascript" src="'+script+'"></script>');   
    horus.script.loaded(script);
} else {
    var s=document.createElement('script');
    s.type='text/javascript';
    s.src=script;
    s.async=true;

    if (horus.brokenDOM){
        s.onreadystatechange=
            function () {
                if (this.readyState=='loaded' || this.readyState=='complete'){
                    horus.script.loaded(script);
                }
        }
    }else{
        s.onload=function () { horus.script.loaded(script) };
    }

    document.head.appendChild(s);
}

where horus.script.loaded() notes that the javascript file is loaded, and calls any pending uncalled routines (saved by autoloader code).

If you imagine the class hierarchy as a tree (as it is in Java), abstract classes can only be branches and final classes are those that can only be leafs. Classes that fall into neither of those categories can be both branches and leafs.

There's no violation of OO principles here, final is simply providing a nice symmetry.

In practice you want to use final if you want your objects to be immutable or if you're writing an API, to signal to the users of the API that the class is just not intended for extension.

You can try this:

Pattern p = Pattern.compile("[a-z]+|\\d+");
Matcher m = p.matcher("123abc345def");
ArrayList<String> allMatches = new ArrayList<>();
while (m.find()) {
    allMatches.add(m.group());
}

The result (allMatches) will be:

["123", "abc", "345", "def"]

Try this way.

                var socket = io.connect('http://...');
                console.log(socket.Socket.sessionid);

    public static void PrintFileToDefaultPrinter(string FilePath)
    {
        try
        {
            var file = File.ReadAllBytes(FilePath);
            var printQueue = LocalPrintServer.GetDefaultPrintQueue();

            using (var job = printQueue.AddJob())
            using (var stream = job.JobStream)
            {
                stream.Write(file, 0, file.Length);
            }
        }
        catch (Exception)
        {

            throw;
        }
    }

I agree with the DialogResult-Solution as the more straight forward one.

In VB.NET however, typecast is required to get the CloseReason-Property

    Private Sub MyForm_Closing(sender As Object, e As CancelEventArgs) Handles Me.Closing

        Dim eCast As System.Windows.Forms.FormClosingEventArgs
        eCast = TryCast(e, System.Windows.Forms.FormClosingEventArgs)
        If eCast.CloseReason = Windows.Forms.CloseReason.None Then
            MsgBox("Button Pressed")
        Else
            MsgBox("ALT+F4 or [x] or other reason")
        End If

    End Sub

If the array happens to be int or anything with the size of int or your mem-pattern's size fits exact times into an int (i.e. all zeroes or 0xA5A5A5A5), the best way is to use memset().

Otherwise call memcpy() in a loop moving the index.

def int_to_bin(num, fill):
    bin_result = ''

    def int_to_binary(number):
        nonlocal bin_result
        if number > 1:
            int_to_binary(number // 2)
        bin_result = bin_result + str(number % 2)

    int_to_binary(num)
    return bin_result.zfill(fill)

The answer by @chepner will copy all the sub-directories irrespective of the fact if it contains the file or not. If you need to exclude the sub-directories that dont contain the file and still retain the directory structure, use

rsync -zarv  --prune-empty-dirs --include "*/"  --include="*.sh" --exclude="*" "$from" "$to"

Just to add another flavor from the Reuben response, I use it like this to add or remove this rule according to a condition:

    RelativeLayout.LayoutParams layoutParams =
            (RelativeLayout.LayoutParams) holder.txtGuestName.getLayoutParams();

    if (SOMETHING_THAT_WOULD_LIKE_YOU_TO_CHECK) {
        // if true center text:
        layoutParams.addRule(RelativeLayout.CENTER_IN_PARENT);
        holder.txtGuestName.setLayoutParams(layoutParams);
    } else {
        // if false remove center:
        layoutParams.addRule(RelativeLayout.CENTER_IN_PARENT, 0);
        holder.txtGuestName.setLayoutParams(layoutParams);
    }

You can do something like:

s = np.random.normal(2, 3, 1000)
import matplotlib.pyplot as plt
count, bins, ignored = plt.hist(s, 30, density=True)
plt.plot(bins, 1/(3 * np.sqrt(2 * np.pi)) * np.exp( - (bins - 2)**2 / (2 * 3**2) ), 
linewidth=2, color='r')
plt.show()

Another map() way to remove list of keys from dictionary

and avoid raising KeyError exception

    dic = {
        'key1': 1,
        'key2': 2,
        'key3': 3,
        'key4': 4,
        'key5': 5,
    }
    
keys_to_remove = ['key_not_exist', 'key1', 'key2', 'key3']
k = list(map(dic.pop, keys_to_remove, keys_to_remove))

print('k=', k)
print('dic after =  \n', dic)

**this will produce output** 

k= ['key_not_exist', 1, 2, 3]
dic after =  {'key4': 4, 'key5': 5}

Duplicate keys_to_remove is artificial, it needs to supply defaults values for dict.pop() function. You can add here any array with len_ = len(key_to_remove)

For example

dic = {
    'key1': 1,
    'key2': 2,
    'key3': 3,
    'key4': 4,
    'key5': 5,
}

keys_to_remove = ['key_not_exist', 'key1', 'key2', 'key3']    
k = list(map(dic.pop, keys_to_remove, np.zeros(len(keys_to_remove))))

print('k=', k)
print('dic after = ', dic)

** will produce output **

k= [0.0, 1, 2, 3]
dic after =  {'key4': 4, 'key5': 5}

TypeScript is one of the best solution for now

TypeScript extends JavaScript by adding types to the language.

https://www.typescriptlang.org/

Try Html.EditorFor helper method instead of Html.TextBoxFor.

For better performance you should use:

var numItems = $('div.item').length;

Since it will only look for the div elements in DOM and will be quick.

Suggestion: using size() instead of length property means one extra step in the processing since SIZE() uses length property in the function definition and returns the result.

Bootstrap 4 is not yet a mature tool yet. The part of requiring another plugin to work is even more complicated especially for developers who have been using Bootstrap for a while. I have seen many ways to eliminate the error but not all work for everyone. I think the best and cleanest way to work with Bootstrap 4. Among the Bootstrap installation files, There is one with the name "bootstrap.bundle.js" that already comes with the Popper included.

If you're using Eclipse, just have your WSDL in a .wsdl file, eclipse will validate it automatically.

From the Doc

The WSDL validator handles validation according to the 4 step process defined above. Steps 1 and 2 are both delegated to Apache Xerces (and XML parser). Step 3 is handled by the WSDL validator and any extension namespace validators (more on extensions below). Step 4 is handled by any declared custom validators (more on this below as well). Each step must pass in order for the next step to run.

Centering content has so many avenues that it can't really be explored in a single answer. If you would like to explore them, CSS Zen Garden is an enjoyable-if-old resource exploring the many, many ways to layout content in a way even old browsers will tolerate.

The correct way, if you don't have any mitigating requirements, is to just apply margin: auto to the sides, and a width. If your page has no content that needs to go outside those margins, just apply it to the body:

body {
  padding: 0;
  margin: 15px auto;
  width: 500px;
}

https://jsfiddle.net/b9chris/62wgq8nk/

So here we've got a 500px wide set of content centered at all* sizes. The padding 0 is to deal with some browsers that like to apply some default padding and throw us off a bit. In the example I do wrap the content in an article tag to be nice to Screen Readers, Pocket, etc so for example the blind can jump past the nav you likely have (which should be in nav) and straight to the content.

I say all* because below 500px this will mess up - we're not being Responsive. To get Responsive, you could just use Bootstrap etc, but building it yourself you use a Media Query like:

body {
  padding: 0;

  margin: 15px;
  @media (min-width: 500px) {
    margin: 15px auto;
    width: 500px;
  }
}

Note that this is SCSS/SASS syntax - if you're using plain CSS, it's inverted:

body {
  padding: 0;  
  margin: 15px;
}

@media (min-width: 500px) {
  body {
    margin: 15px auto;
    width: 500px;
  }
}

https://jsfiddle.net/b9chris/62wgq8nk/6/

It's common however to want to center just one chunk of a page, so let's apply this to only the article tag in a final example.

body {
  padding: 0;
  margin: 0;
}

nav {
  width: 100%;
  box-sizing: border-box;
  padding: 15px;
}

article {
  margin: 15px;
  @media (min-width: 500px) {
    margin: 15px auto;
    width: 500px;
  }
}

https://jsfiddle.net/b9chris/62wgq8nk/17/

Note that this final example also uses CSS Flexbox in the nav, which is also one of the newer ways you could center things. So, that's fun.

But, there are special circumstances where you need to use other approaches to center content, and each of those is probably worth its own question (many of them already asked and answered here on this site).

In Hadoop 2.0,

hdfs dfs -copyToLocal <hdfs_input_file_path> <output_path>

where,

• hdfs_input_file_path maybe obtained from http://<<name_node_ip>>:50070/explorer.html

• output_path is the local path of the file, where the file is to be copied to.

• you may also use get in place of copyToLocal.

An easier way to do this is using crop from ImageOps. You can feed the number of pixels you want to crop from each side.

from PIL import ImageOps

border = (0, 30, 0, 30) # left, up, right, bottom
ImageOps.crop(img, border)

"-TotalCount" in this instance responds exactly like "-head". You have to use -TotalCount or -head to run the command like that. But -TotalCount is misleading - it does not work in ACTUALLY giving you ANY counts...

gc -TotalCount 25 C:\scripts\logs\robocopy_report.txt

The above script, tested in PS 5.1 is the SAME response as below...

gc -head 25 C:\scripts\logs\robocopy_report.txt

So then just use '-head 25" already!

Here is how you can read the entire file contents, and if done successfully, start a webserver which displays the JPG image in response to every request:

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

fs.readFile('image.jpg', function(err, data) {
  if (err) throw err // Fail if the file can't be read.
  http.createServer(function(req, res) {
    res.writeHead(200, {'Content-Type': 'image/jpeg'})
    res.end(data) // Send the file data to the browser.
  }).listen(8124)
  console.log('Server running at http://localhost:8124/')
})

Note that the server is launched by the "readFile" callback function and the response header has Content-Type: image/jpeg.

[Edit] You could even embed the image in an HTML page directly by using an <img> with a data URI source. For example:

  res.writeHead(200, {'Content-Type': 'text/html'});
  res.write('<html><body><img src="data:image/jpeg;base64,')
  res.write(Buffer.from(data).toString('base64'));
  res.end('"/></body></html>');

don't need regex just use classlist

var id=document.getElementById('myButton');


function toggle(el,classname){
if(el.classList.contains(classname)){
el.classList.remove(classname)
}
else{
el.classList.add(classname)
}
}




id.addEventListener('click',(e)=>{

toggle(e.target,'red')
})

.red{

background:red

}

<button id="myButton">Switch</button>

Simple Usage above Example

var id=document.getElementById('myButton');


function toggle(el,classname){
el.classList.toggle(classname)
}




id.addEventListener('click',(e)=>{

toggle(e.target,'red')
})

.red{

background:red

}

<button id="myButton">Switch</button>

When you run the Windows Command Prompt, and type in python, it starts the Python interpreter.

Typing it again tries to interpret python as a variable, which doesn't exist and thus won't work:

Microsoft Windows [Version 6.1.7601]
Copyright (c) 2009 Microsoft Corporation.  All rights reserved.

C:\Users\USER>python
Python 2.7.5 (default, May 15 2013, 22:43:36) [MSC v.1500 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.

NameError: name 'python' is not defined
>>> print("interpreter has started")

>>> quit() # leave the interpreter, and go back to the command line

C:\Users\USER>

If you're not doing this from the command line, and instead running the Python interpreter (python.exe or IDLE's shell) directly, you are not in the Windows Command Line, and python is interpreted as a variable, which you have not defined.

There is no such font as “Calibri (Body)”. You probably saw this string in Microsoft Word font selection menu, but it’s not a font name (see e.g. the explanation Font: +body (in W07)).

So use just font-family: Calibri or, better, font-family: Calibri, sans-serif. (There is no adequate backup font for Calibri, but the odds are that when Calibri is not available, the browser’s default sans-serif font suits your design better than the browser’s default font, which is most often a serif font.)

Here it is:

function call_func(input) {
    var evaled = eval('(' + input + ')');
    var newDiv = document.createElement('div');
    var id = evaled.id;
    var name = evaled.Student_name;
    var dob = evaled.student_dob;
    var html = '<b>ID:</b>';
    html += '<a href="/learningyii/index.php?r=student/view&amp; id=' + id + '">' + id + '</a>';
    html += '<br/>';
    html += '<b>Student Name:</b>';
    html += name;
    html += '<br/>';
    html += '<b>Student DOB:</b>';
    html += dob;
    html += '<br/>';
    newDiv.innerHTML = html;
    newDiv.setAttribute('class', 'view');
    $('#StudentGridViewId').find('.items').prepend(newDiv);
};

if [ "$b" -eq 5 ]; then a="$c"; else a="$d"; fi

The cond && op1 || op2 expression suggested in other answers has an inherent bug: if op1 has a nonzero exit status, op2 silently becomes the result; the error will also not be caught in -e mode. So, that expression is only safe to use if op1 can never fail (e.g., :, true if a builtin, or variable assignment without any operations that can fail (like division and OS calls)).

Note the "" quotes. The first pair will prevent a syntax error if $b is blank or has whitespace. Others will prevent translation of all whitespace into single spaces.

var logged_in = false;

You won't be able to get that from a TimeSpan, because a "month" is a variable unit of measure. You'll have to calculate it yourself, and you'll have to figure out how exactly you want it to work.

For example, should dates like July 5, 2009 and August 4, 2009 yield one month or zero months difference? If you say it should yield one, then what about July 31, 2009 and August 1, 2009? Is that a month? Is it simply the difference of the Month values for the dates, or is it more related to an actual span of time? The logic for determining all of these rules is non-trivial, so you'll have to determine your own and implement the appropriate algorithm.

If all you want is simply a difference in the months--completely disregarding the date values--then you can use this:

public static int MonthDifference(this DateTime lValue, DateTime rValue)
{
    return (lValue.Month - rValue.Month) + 12 * (lValue.Year - rValue.Year);
}

Note that this returns a relative difference, meaning that if rValue is greater than lValue, then the return value will be negative. If you want an absolute difference, you can use this:

public static int MonthDifference(this DateTime lValue, DateTime rValue)
{
    return Math.Abs((lValue.Month - rValue.Month) + 12 * (lValue.Year - rValue.Year));
}

No longer works for spreadsheets Protected with Excel 2013 or later -- they improved the pw hash. So now need to unzip .xlsx and hack the internals.

A TextBlock does not actually inherit from Control so it does not have properties that you would generally associate with a Control. Your best bet for adding a border in a style is to replace the TextBlock with a Label

See this link for more on the differences between a TextBlock and other Controls

Use the reset function, which is available on the form element.

var form = document.getElementById("myForm");
form.reset();

If the goal is to seperate two elements, you can use CSS like below:

A<span style={{paddingLeft: '20px'}}>B</span>

If you are using Carbon you can do the following. You could also format this date to set an Expire HTTP Header.

Carbon::parse('tomorrow midnight')->format(Carbon::RFC7231_FORMAT)

Looks like this is new as of Python 3.4 - pathlib.

from pathlib import Path

Path('path/to/file.txt').touch()

This will create a file.txt at the path.

--

Path.touch(mode=0o777, exist_ok=True)

Create a file at this given path. If mode is given, it is combined with the process’ umask value to determine the file mode and access flags. If the file already exists, the function succeeds if exist_ok is true (and its modification time is updated to the current time), otherwise FileExistsError is raised.

Google gives a breakdown of these fields in the Evaluating network performance section of their DevTools documentation.

Excerpt from Resource network timing:

Stalled/Blocking

Time the request spent waiting before it could be sent. This time is inclusive of any time spent in proxy negotiation. Additionally, this time will include when the browser is waiting for an already established connection to become available for re-use, obeying Chrome's maximum six TCP connection per origin rule.

(If you forget, Chrome has an "Explanation" link in the hover tooltip and under the "Timing" panel.)

Basically, the primary reason you will see this is because Chrome will only download 6 files per-server at a time and other requests will be stalled until a connection slot becomes available.

This isn't necessarily something that needs fixing, but one way to avoid the stalled state would be to distribute the files across multiple domain names and/or servers, keeping CORS in mind if applicable to your needs, however HTTP2 is probably a better option going forward. Resource bundling (like JS and CSS concatenation) can also help to reduce amount of stalled connections.

The simplest fix is to make the comparator function be static:

static int comparator (const Bar & first, const Bar & second);
^^^^^^

When invoking it in Count, its name will be Foo::comparator.

The way you have it now, it does not make sense to be a non-static member function because it does not use any member variables of Foo.

Another option is to make it a non-member function, especially if it makes sense that this comparator might be used by other code besides just Foo.

import java.util.Scanner;

public class SumAll {
    public static void sumAll(int arr[]) {//initialize method return sum
        int sum = 0;
        for (int i = 0; i < arr.length; i++) {
            sum += arr[i];
        }
        System.out.println("Sum is : " + sum);
    }

    public static void main(String[] args) {
        int num;
        Scanner input = new Scanner(System.in);//create scanner object 
        System.out.print("How many # you want to add : ");
        num = input.nextInt();//return num from keyboard
        int[] arr2 = new int[num];
        for (int i = 0; i < arr2.length; i++) {
            System.out.print("Enter Num" + (i + 1) + ": ");
            arr2[i] = input.nextInt();
        }
        sumAll(arr2);
    }

}

Edit Looking back, this is non-idiomatic Go. Small helper functions like this add an extra step of complexity. In general, the Go philosophy prefers to include the 3 simple lines over 1 tricky line.

As @robyoder mentioned, json.Indent is the way to go. Thought I'd add this small prettyprint function:

package main

import (
    "bytes"
    "encoding/json"
    "fmt"
)

//dont do this, see above edit
func prettyprint(b []byte) ([]byte, error) {
    var out bytes.Buffer
    err := json.Indent(&out, b, "", "  ")
    return out.Bytes(), err
}

func main() {
    b := []byte(`{"hello": "123"}`)
    b, _ = prettyprint(b)
    fmt.Printf("%s", b)
}

I had the same issue with a site which previously was running fine. I resolved the issue by deleting the temporary files from C:\WINDOWS\Microsoft.NET\Framework\v#.#.#####\Temporary ASP.NET Files\@projectName\###CC##C\###C#CC

I had to change my values/styles.xml to

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar">

Before that change, it was without 'Base'.

One thing to be aware of is that many Linux netfilter firewalls are misconfigured.

If you have something like:

-A FORWARD -m state --state RELATED,ESTABLISHED -j ACCEPT

-A FORWARD -p tcp -j REJECT --reject-with tcp-reset

then packet reordering can result in the firewall considering the packets invalid and thus generating resets which will then break otherwise healthy connections.

Reordering is particularly likely with a wireless network.

This should instead be:

-A FORWARD -m state --state RELATED,ESTABLISHED -j ACCEPT

-A FORWARD -m state --state INVALID -j DROP

-A FORWARD -p tcp -j REJECT --reject-with tcp-reset

Basically anytime you have:

... -m state --state RELATED,ESTABLISHED -j ACCEPT

it should immediately be followed by:

... -m state --state INVALID -j DROP

It's better to drop a packet then to generate a potentially protocol disrupting tcp reset. Resets are better when they're provably the correct thing to send... since this eliminates timeouts. But if there's any chance they're invalid then they can cause this sort of pain.

I think the fix is relative easy without disabling this feature.

All you need to do is add the triple double quotes string in every function.

Am i understanding your question only? You need .bat file to compile and execute java class files?

if its a .bat file. you can just double click.

and in your .bat file, you just need to javac Main.java ((make sure your bat has the path to ur Main.java) java Main

If you want to echo compilation warnings/statements, that would need something else. But since, you want that to be automated, maybe you eventually don't need that.

You need to set the OFS variable (output field separator) to be a tab:

echo "$line" | 
awk -v var="$mycol_new" -F $'\t' 'BEGIN {OFS = FS} {$3 = var; print}'

(make sure you quote the $line variable in the echo statement)

If you want to change whether it highlights the best fitting possibility, use:

Ctrl + Alt + Space

use datejs

new Date().toString('yyyy-MM-d-h-mm-ss');

This jQuery worked for me in IE11, Chrome 53, and Firefox 49:

cloned = $("#fileInput").clone(true);
cloned.val("");
$("#fileInput").replaceWith(cloned);

Yes it possible to have constructor in structure here is one example:

#include<iostream.h> 
struct a {
  int x;
  a(){x=100;}
};

int main() {
  struct a a1;
  getch();
}

I found the best solution for me, after reading all your answers:

set t=%date%_%time%
set d=%t:~10,4%%t:~7,2%%t:~4,2%_%t:~15,2%%t:~18,2%%t:~21,2%
echo hello>"Archive_%d%"

If AM I get 20160915_ 150101 (with a leading space and time).

If PM I get 20160915_2150101.

Generally, this is how you open an OS folder containing a bunch of vdmk files on VMware Player.

I have written down the steps:

? Add gem 'newrelic_rpm' to your Gemfile under staging & production
? bundle install
? Login to heroku control panel and add newrelic addon
? Once added, setup automatic pinging to your website so that it does not idle
? Browse to Menu > Availability Monitoring (under Settings) ? Click “Turn on Availability Monitoring”
? Enter the url to ping (eg: http://spokenvote.org)
? Select 1 minute for the interval

Which version of bootstrap are you using? The early versions of Bootstrap 3 (3.0, 3.0.1) didn't work with this functionality.

col-md-offset-0 should be working as seen in this bootstrap example found here (http://getbootstrap.com/css/#grid-responsive-resets):

<div class="row">
   <div class="col-sm-5 col-md-6">.col-sm-5 .col-md-6</div>
   <div class="col-sm-5 col-sm-offset-2 col-md-6 col-md-offset-0">.col-sm-5 .col-sm-offset-2 .col-md-6 .col-md-offset-0</div>
</div>

If there is no selection, you can use the properties .selectionStart or .selectionEnd (with no selection they're equal).

var cursorPosition = $('#myTextarea').prop("selectionStart");

Note that this is not supported in older browsers, most notably IE8-. There you'll have to work with text ranges, but it's a complete frustration.

I believe there is a library somewhere which is dedicated to getting and setting selections/cursor positions in input elements, though. I can't recall its name, but there seem to be dozens on articles about this subject.

I think you should do it like this, if you want to validate table not to use email twice

Code :

INSERT INTO tablename(fullname,email) 

SELECT * FROM (SELECT 'fullnameValue' AS fullname_field,'emailValue' AS email_field) entry WHERE entry.email_field NOT IN (SELECT email FROM tablename);

... using org.apache.http api. ...

You need to include SOAPAction as a header in the request. As you have httpPost and requestWrapper handles, there are three ways adding the header.

 1. httpPost.addHeader( "SOAPAction", strReferenceToSoapActionValue );
 2. httpPost.setHeader( "SOAPAction", strReferenceToSoapActionValue );
 3. requestWrapper.setHeader( "SOAPAction", strReferenceToSoapActionValue );

Only difference is that addHeader allows multiple values with same header name and setHeader allows unique header names only. setHeader(... over writes first header with the same name.

You can go with any of these on your requirement.

assuming both elements have 50% width, here is what i used:

css:

  .parent {
    width: 100%;
    display: flex;
  }  
  .child-1 {
    width: 50%;
    margin-right: -50%;
    margin-left: 50%;
    background: #ff0;
  }
  .child-2 {
    width: 50%;
    margin-right: 50%;
    margin-left: -50%;
    background: #0f0;
  }

html:

<div class="parent">
  <div class="child-1">child1</div>
  <div class="child-2">child2</div>
</div>

example: https://jsfiddle.net/gzveri/o6umhj53/

btw, this approach works for any 2 nearby elements in a long list of elements. For example I have a long list of elements with 2 items per row and I want each 3-rd and 4-th element in the list to be swapped, so that it renders elements in a chess style, then I use these rules:

  .parent > div:nth-child(4n+3) {
    margin-right: -50%;
    margin-left: 50%;
  }
  .parent > div:nth-child(4n+4) {
    margin-right: 50%;
    margin-left: -50%;
  }

int i;
  cout << "Please enter an integer value: ";

  // cin >> i; leaves '\n' among possible other junk in the buffer. 
  // '\n' also happens to be the default delim character for getline() below.
  cin >> i; 
  if (cin.fail()) 
  {
    cout << "\ncin failed - substituting: i=1;\n\n";
    i = 1;
  }
  cin.clear(); cin.ignore(INT_MAX,'\n'); 

  cout << "The value you entered is: " << i << " and its double is " << i*2 << ".\n\n";

  string myString;
  cout << "What's your full name? (spaces inclded) \n";
  getline (cin, myString);
  cout << "\nHello '" << myString << "'.\n\n\n";

You are supposed to check the mutex variable before using the area protected by the mutex. So your pthread_mutex_lock() could (depending on implementation) wait until mutex1 is released or return a value indicating that the lock could not be obtained if someone else has already locked it.

Mutex is really just a simplified semaphore. If you read about them and understand them, you understand mutexes. There are several questions regarding mutexes and semaphores in SO. Difference between binary semaphore and mutex, When should we use mutex and when should we use semaphore and so on. The toilet example in the first link is about as good an example as one can think of. All code does is to check if the key is available and if it is, reserves it. Notice that you don't really reserve the toilet itself, but the key.

For AngularJS users:

$window.grecaptcha.reset();

Use "&" instead of "&".

Solution(s) for this, found in the official wampserver.com forums:

SOLUTION #1:

This problem is caused by Windows (7) in combination with any software that also uses port 80 (like Skype or IIS (which is installed on most developer machines)). A video solution can be found here (34.500+ views, damn, this seems to be a big thing ! EDIT: The video now has ~60.000 views ;) )

To make it short: open command line tool, type "netstat -aon" and look for any lines that end of ":80". Note thatPID on the right side. This is the process id of the software which currently usesport 80. Press AltGr + Ctrl + Del to get into the Taskmanager. Switch to the tab where you can see all services currently running, ordered by PID. Search for that PID you just notices and stop that thing (right click). To prevent this in future, you should config the software's port settings (skype can do that).

SOLUTION #2:

left click the wamp icon in the taskbar, go to apache > httpd.conf and edit this file: change "listen to port .... 80" to 8080. Restart. Done !

SOLUTION #3:

Port 80 blocked by "Microsoft Web Deployment Service", simply deinstall this, more info here

By the way, it's not Microsoft's fault, it's a stupid usage of ports by most WAMP stacks.

IMPORTANT: you have to use localhost or 127.0.0.1 now with port 8080, this means 127.0.0.1:8080 or localhost:8080.

I use the following method:

public static <T> T getBean(final String beanName, final Class<T> clazz) {
    ELContext elContext = FacesContext.getCurrentInstance().getELContext();
    return (T) FacesContext.getCurrentInstance().getApplication().getELResolver().getValue(elContext, null, beanName);
}

This allows me to get the returned object in a typed manner.

you can swipe the key and the value. For example

        String[] k = {"Elena", "Thomas", "Hamilton", "Suzie", "Phil"};
        int[] v = {341, 273, 278, 329, 445};
        TreeMap<Integer,String>a=new TreeMap();
        for (int i = 0; i < k.length; i++) 
           a.put(v[i],k[i]);            
        System.out.println(a.firstEntry().getValue()+"\t"+a.firstEntry().getKey());
        a.remove(a.firstEntry().getKey());
        System.out.println(a.firstEntry().getValue()+"\t"+a.firstEntry().getKey());

_{In addition to romkyns's great answer.. here is some relevant documentation/examples.}

DOM Elements have a native .click() method.

The HTMLElement.click() method simulates a mouse click on an element.

When click is used, it also fires the element's click event which will bubble up to elements higher up the document tree (or event chain) and fire their click events too. However, bubbling of a click event will not cause an <a> element to initiate navigation as if a real mouse-click had been received. (mdn reference)

Relevant W3 documentation.

A few examples..

• You can access a specific DOM element from a jQuery object: (example)

    $('a')[0].click();
  

• You can use the .get() method to retrieve a DOM element from a jQuery object: (example)

    $('a').get(0).click();
  

• As expected, you can select the DOM element and call the .click() method. (example)

    document.querySelector('a').click();
  

It's worth pointing out that jQuery is not required to trigger a native .click() event.

I did all of them but didn't work, I find out should stop php artisan serve(Ctrl + C) and start php artisan serve again.

This just means that the git clone copied the files down from github and placed them into a folder. If you try to do it again it will not let you because it can't clone into a folder that has files into it. So if you think the git clone did not complete properly, just delete the folder and do the git clone again. The clone creates a folder the same name as the git repo.

You could try to put a ServletFilter in front of the webservice and inspect request and response going to / returned from the service.

Although you specifically did not ask for a proxy, sometimes I find tcptrace is enough to see what goes on on a connection. It's a simple tool, no install, it does show the data streams and can write to file too.

I wrote my own library to achieve the intended behaviour in ios Maps app. It is a protocol oriented solution. So you don't need to inherit any base class instead create a sheet controller and configure as you wish. It also supports inner navigation/presentation with or without UINavigationController.

See below link for more details.

One can use PrintWriter to wrap the FileWriter, as it has many additional useful methods.

try(PrintWriter pw = new PrintWriter(new FileWriter(new File("file.txt"), false))){
   pw.println();//new line
   pw.print("text");//print without new line
   pw.println(10);//print with new line
   pw.printf("%2.f", 0.567);//print double to 2 decimal places (without new line)
}

The other solutions did not work for me out of the box. I think perhaps because I am using a more recent version of Bootstrap (3.3.2).... the overlay was appearing on top of the modal dialog.

I refactored the code a bit and commented out the part that was adjusting the modal-backdrop. This fixed the issue.

    var $body = $('body');
    var OPEN_MODALS_COUNT = 'fv_open_modals';
    var Z_ADJUSTED = 'fv-modal-stack';
    var defaultBootstrapModalZindex = 1040;

    // keep track of the number of open modals                   
    if ($body.data(OPEN_MODALS_COUNT) === undefined) {
        $body.data(OPEN_MODALS_COUNT, 0);
    }

    $body.on('show.bs.modal', '.modal', function (event)
    {
        if (!$(this).hasClass(Z_ADJUSTED))  // only if z-index not already set
        {
            // Increment count & mark as being adjusted
            $body.data(OPEN_MODALS_COUNT, $body.data(OPEN_MODALS_COUNT) + 1);
            $(this).addClass(Z_ADJUSTED);

            // Set Z-Index
            $(this).css('z-index', defaultBootstrapModalZindex + (1 * $body.data(OPEN_MODALS_COUNT)));

            //// BackDrop z-index   (Doesn't seem to be necessary with Bootstrap 3.3.2 ...)
            //$('.modal-backdrop').not( '.' + Z_ADJUSTED )
            //        .css('z-index', 1039 + (10 * $body.data(OPEN_MODALS_COUNT)))
            //        .addClass(Z_ADJUSTED);
        }
    });
    $body.on('hidden.bs.modal', '.modal', function (event)
    {
        // Decrement count & remove adjusted class
        $body.data(OPEN_MODALS_COUNT, $body.data(OPEN_MODALS_COUNT) - 1);
        $(this).removeClass(Z_ADJUSTED);
        // Fix issue with scrollbar being shown when any modal is hidden
        if($body.data(OPEN_MODALS_COUNT) > 0)
            $body.addClass('modal-open');
    });

As a side note, if you want to use this in AngularJs, just put the code inside of your module's .run() method.

One thing that needs to be mentioned. You have to use the x86 version of Python 2.7. OpenCV doesn't support Python x64. I banged my head on this for a bit until I figured that out.

That said, follow the steps in Abid Rahman K's answer. And as Antimony said, you'll need to do a 'from cv2 import cv'

Facebook's photo gallery does this using a #hash in the URL. Here are some example URLs:

Before clicking 'next':

/photo.php?fbid=496429237507&set=a.218088072507.133423.681812507&pid=5887027&id=681812507

After clicking 'next':

/photo.php?fbid=496429237507&set=a.218088072507.133423.681812507&pid=5887027&id=681812507#!/photo.php?fbid=496435457507&set=a.218088072507.133423.681812507&pid=5887085&id=681812507

Note the hash-bang (#!) immediately followed by the new URL.

If you already have nodejs installed (check with which nodejs) and don't want to install another package, you can, as root:

update-alternatives --install /usr/bin/node node /usr/bin/nodejs 99

You have a class on your CSS that is overwriting your width and height, the class reads as such:

.postItem img {
    height: auto;
    width: 450px;
}

Remove that and your width/height properties on the img tag should work.

There are 94 Unicode characters which can be represented as one byte according to the JSON spec (if your JSON is transmitted as UTF-8). With that in mind, I think the best you can do space-wise is base85 which represents four bytes as five characters. However, this is only a 7% improvement over base64, it's more expensive to compute, and implementations are less common than for base64 so it's probably not a win.

You could also simply map every input byte to the corresponding character in U+0000-U+00FF, then do the minimum encoding required by the JSON standard to pass those characters; the advantage here is that the required decoding is nil beyond builtin functions, but the space efficiency is bad -- a 105% expansion (if all input bytes are equally likely) vs. 25% for base85 or 33% for base64.

Final verdict: base64 wins, in my opinion, on the grounds that it's common, easy, and not bad enough to warrant replacement.

1. Open a command prompt and go to the directory where Postgres installed. In my case my Postgres path is "D:\TOOLS\Postgresql-9.4.1-3".After that move to the bin directory of Postgres.So command prompt shows as "D:\TOOLS\Postgresql-9.4.1-3\bin>"
2. Now my goal is to select "UserName" from the users table using "UserId" value.So the database query is "Select u."UserName" from users u Where u."UserId"=1".

The same query is written as below for psql command prompt of postgres.

D:\TOOLS\Postgresql-9.4.1-3\bin>psql -U postgres -d DatabaseName -h localhost - t -c "Select u.\"UserName\" from users u Where u.\"UserId\"=1;

In the last line of the batch file that you want to keep open put a

pause >nul

I think the problem is that when you're trying to compile testpoint.c, it includes point.h but it doesn't know about point.c. Since point.c has the definition for create, not having point.c will cause the compilation to fail.

I'm not familiar with MinGW, but you need to tell the compiler to look for point.c. For example with gcc you might do this:

gcc point.c testpoint.c

As others have pointed out, you also need to remove one of your main functions, since you can only have one.

if you don't want recursion you could try:

x = [u'sam', [['Test', [['one', [], []]], [(u'file.txt', ['id', 1, 0])]], ['Test2', [], [(u'file2.txt', ['id', 1, 2])]]], []]
layer1=x
layer2=[]
while True:
    for i in layer1:
        if isinstance(i,list):
            for j in i:
                layer2.append(j)
        else:
            print i
    layer1[:]=layer2
    layer2=[]
    if len(layer1)==0:
        break

which gives:

sam
Test
Test2
(u'file.txt', ['id', 1, 0])
(u'file2.txt', ['id', 1, 2])
one

(note that it didn't look into the tuples for lists because the tuples aren't lists. You can add tuple to the "isinstance" method if you want to fix this)

Add this line before any output of the body, in the event you aren't using output buffering.

header("HTTP/1.1 200 OK");

Replace the message portion ('OK') with the appropriate message, and the status code with your code as appropriate (404, 501, etc)

Swift 3

Time format 24 hours to 12 hours

let dateAsString = "13:15"
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "HH:mm"

let date = dateFormatter.date(from: dateAsString)
dateFormatter.dateFormat = "h:mm a"
let Date12 = dateFormatter.string(from: date!)
print("12 hour formatted Date:",Date12)

output will be 12 hour formatted Date: 1:15 PM

Time format 12 hours to 24 hours

let dateAsString = "1:15 PM"
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "h:mm a"

let date = dateFormatter.date(from: dateAsString)
dateFormatter.dateFormat = "HH:mm"

let Date24 = dateFormatter.string(from: date!)
print("24 hour formatted Date:",Date24)

output will be 24 hour formatted Date: 13:15

You need to define the enum outside of the class.

public enum card_suits
{
    Clubs,
    Hearts,
    Spades,
    Diamonds
}

public class Card
{
     // ...

That being said, you may also want to consider using the standard naming guidelines for Enums, which would be CardSuit instead of card_suits, since Pascal Casing is suggested, and the enum is not marked with the FlagsAttribute, suggesting multiple values are appropriate in a single variable.

I haven't found a clear answer, without checks if it is negative or positive, that uses two's complement (negative numbers included). For that, I show my solution to one byte:

((0xFF + number +1) & 0x0FF).toString(16);

You can use this instruction to any number bytes, only you add FF in respective places. For example, to two bytes:

((0xFFFF + number +1) & 0x0FFFF).toString(16);

If you want cast an array integer to string hexadecimal:

s = "";
for(var i = 0; i < arrayNumber.length; ++i) {
    s += ((0xFF + arrayNumber[i] +1) & 0x0FF).toString(16);
}

String search = "A";
for(String s : myList)
    if(s.contains(search)) return true;
return false;

This will iterate over each string in the list, and check if it contains the string you're looking for. If it's only spaces you want to trap for, you can do this:

String search = "A";
for(String s : myList)
    if(s.replaceAll(" ","").contains(search)) return true;
return false;

which will first replace spaces with empty strings before searching. Additionally, if you just want to trim the string first, you can do:

String search = "A";
for(String s : myList)
    if(s.trim().contains(search)) return true;
return false;

Updating to use tibble()

You can pass a named vector of length greater than 1 to the by argument of left_join():

library(dplyr)

d1 <- tibble(
  x = letters[1:3],
  y = LETTERS[1:3],
  a = rnorm(3)
  )

d2 <- tibble(
  x2 = letters[3:1],
  y2 = LETTERS[3:1],
  b = rnorm(3)
  )

left_join(d1, d2, by = c("x" = "x2", "y" = "y2"))

This elegant solution works great on SWIFT 3.0, SWIFT 4.2 and SWIFT 5.1:

On the Storyboard:

1. Select your Tab Bar
2. Set a Runtime Attibute called tintColor for the desired color of the Selected Icon on the tab bar
3. Set a Runtime Attibute called unselectedItemTintColor for the desired color of the Unselected Icon on the tab bar

Super Key : Super key is a set of one or more attributes whose values identify tuple in the relation uniquely.

Candidate Key : Candidate key can be defined as a minimal subset of super key. In some cases , candidate key can not alone since there is alone one attribute is the minimal subset. Example,

Employee(id, ssn, name, addrress)

Here Candidate key is (id, ssn) because we can easily identify the tuple using either id or ssn . Althrough, minimal subset of super key is either id or ssn. but both of them can be considered as candidate key.

Primary Key : Primary key is a one of the candidate key.

Example : Student(Id, Name, Dept, Result)

Here

Super Key : {Id, Id+Name, Id+Name+Dept} because super key is set of attributes .

Candidate Key : Id because Id alone is the minimal subset of super key.

Primary Key : Id because Id is one of the candidate key

Apples and oranges. Firebase is a Backend-as-a-Service containing identity management, realtime data views and a document database. It runs in the cloud.

MongoDB on the other hand is a full fledged database with a rich query language. In principle it runs on your own machine, but there are cloud providers.

If you are looking for the database component only MongoDB is much more mature and feature-rich.

Here is a class I use when writing services. I usually have an interactive screen that comes up when the service is not called. From there I use the class as needed. It allows for multiple named instances on the same machine -hence the InstanceID field

Sample Call

  IntegratedServiceInstaller Inst = new IntegratedServiceInstaller();
  Inst.Install("MySvc", "My Sample Service", "Service that executes something",
                    _InstanceID,
// System.ServiceProcess.ServiceAccount.LocalService,      // this is more secure, but only available in XP and above and WS-2003 and above
  System.ServiceProcess.ServiceAccount.LocalSystem,       // this is required for WS-2000
  System.ServiceProcess.ServiceStartMode.Automatic);
  if (controller == null)
  {
    controller = new System.ServiceProcess.ServiceController(String.Format("MySvc_{0}", _InstanceID), ".");
                }
                if (controller.Status == System.ServiceProcess.ServiceControllerStatus.Running)
                {
                    Start_Stop.Text = "Stop Service";
                    Start_Stop_Debugging.Enabled = false;
                }
                else
                {

Simply create an object of Base64 and use it to encode or decode, when using org.apache.commons.codec.binary.Base64 library

To Encode

Base64 ed=new Base64();

String encoded=new String(ed.encode("Hello".getBytes()));

Replace "Hello" with the text to be encoded in String Format.

To Decode

Base64 ed=new Base64();

String decoded=new String(ed.decode(encoded.getBytes()));

Here encoded is the String variable to be decoded

Not sure you resolved this issue or not, but this is how I do it and it works on Android:

1. Use openssl to merge client's cert(cert must be signed by a CA that accepted by server) and private key into a PCKS12 format key pair: openssl pkcs12 -export -in clientcert.pem -inkey clientkey.pem -out client.p12
2. You may need patch your JRE to umlimited strength encryption depends on your key strength: copy the jar files fromJCE 5.0 unlimited strength Jurisdiction Policy FIles and override those in your JRE (eg.C:\Program Files\Java\jre6\lib\security)
3. Use Portecle tool mentioned above and create a new keystore with BKS format
4. Import PCKS12 key pair generated in step 1 and save it as BKS keystore. This keystore works with Android client authentication.
5. If you need to do certificate chain, you can use this IBM tool:KeyMan to merge client's PCKS12 key pair with CA cert. But it only generate JKS keystore, so you again need Protecle to convert it to BKS format.

First, the extensions and libraries that we're going to use:

{-# LANGUAGE RankNTypes, TypeOperators #-}

import Control.Monad (join)

Of these, RankNTypes is the only one that's absolutely essential to the below. I once wrote an explanation of RankNTypes that some people seem to have found useful, so I'll refer to that.

Quoting Tom Crockett's excellent answer, we have:

A monad is...

• An endofunctor, T : X -> X
• A natural transformation, µ : T × T -> T, where × means functor composition
• A natural transformation, ? : I -> T, where I is the identity endofunctor on X

...satisfying these laws:

• µ(µ(T × T) × T)) = µ(T × µ(T × T))
• µ(?(T)) = T = µ(T(?))

How do we translate this to Haskell code? Well, let's start with the notion of a natural transformation:

-- | A natural transformations between two 'Functor' instances.  Law:
--
-- > fmap f . eta g == eta g . fmap f
--
-- Neat fact: the type system actually guarantees this law.
--
newtype f :-> g =
    Natural { eta :: forall x. f x -> g x }

A type of the form f :-> g is analogous to a function type, but instead of thinking of it as a function between two types (of kind *), think of it as a morphism between two functors (each of kind * -> *). Examples:

listToMaybe :: [] :-> Maybe
listToMaybe = Natural go
    where go [] = Nothing
          go (x:_) = Just x

maybeToList :: Maybe :-> []
maybeToList = Natural go
    where go Nothing = []
          go (Just x) = [x]

reverse' :: [] :-> []
reverse' = Natural reverse

Basically, in Haskell, natural transformations are functions from some type f x to another type g x such that the x type variable is "inaccessible" to the caller. So for example, sort :: Ord a => [a] -> [a] cannot be made into a natural transformation, because it's "picky" about which types we may instantiate for a. One intuitive way I often use to think of this is the following:

• A functor is a way of operating on the content of something without touching the structure.
• A natural transformation is a way of operating on the structure of something without touching or looking at the content.

Now, with that out of the way, let's tackle the clauses of the definition.

The first clause is "an endofunctor, T : X -> X." Well, every Functor in Haskell is an endofunctor in what people call "the Hask category," whose objects are Haskell types (of kind *) and whose morphisms are Haskell functions. This sounds like a complicated statement, but it's actually a very trivial one. All it means is that that a Functor f :: * -> * gives you the means of constructing a type f a :: * for any a :: * and a function fmap f :: f a -> f b out of any f :: a -> b, and that these obey the functor laws.

Second clause: the Identity functor in Haskell (which comes with the Platform, so you can just import it) is defined this way:

newtype Identity a = Identity { runIdentity :: a }

instance Functor Identity where
    fmap f (Identity a) = Identity (f a)

So the natural transformation ? : I -> T from Tom Crockett's definition can be written this way for any Monad instance t:

return' :: Monad t => Identity :-> t
return' = Natural (return . runIdentity)

Third clause: The composition of two functors in Haskell can be defined this way (which also comes with the Platform):

newtype Compose f g a = Compose { getCompose :: f (g a) }

-- | The composition of two 'Functor's is also a 'Functor'.
instance (Functor f, Functor g) => Functor (Compose f g) where
    fmap f (Compose fga) = Compose (fmap (fmap f) fga)

So the natural transformation µ : T × T -> T from Tom Crockett's definition can be written like this:

join' :: Monad t => Compose t t :-> t
join' = Natural (join . getCompose)

The statement that this is a monoid in the category of endofunctors then means that Compose (partially applied to just its first two parameters) is associative, and that Identity is its identity element. I.e., that the following isomorphisms hold:

• Compose f (Compose g h) ~= Compose (Compose f g) h
• Compose f Identity ~= f
• Compose Identity g ~= g

These are very easy to prove because Compose and Identity are both defined as newtype, and the Haskell Reports define the semantics of newtype as an isomorphism between the type being defined and the type of the argument to the newtype's data constructor. So for example, let's prove Compose f Identity ~= f:

Compose f Identity a
    ~= f (Identity a)                 -- newtype Compose f g a = Compose (f (g a))
    ~= f a                            -- newtype Identity a = Identity a

From within less (in Linux):

 g and the line number to go forward

 G and the line number to go backwards

Used alone, g and G will take you to the first and last line in a file respectively; used with a number they are both equivalent.

An example; you want to go to line 320123 of a file,

press 'g' and after the colon type in the number 320123

Additionally you can type '-N' inside less to activate / deactivate the line numbers. You can as a matter of fact pass any command line switches from inside the program, such as -j or -N.

NOTE: You can provide the line number in the command line to start less (less +number -N) which will be much faster than doing it from inside the program:

less +12345 -N /var/log/hugelogfile

This will open a file displaying the line numbers and starting at line 12345

As you stated in the comments, some of the values appeared to be floats, not strings. You will need to change it to strings before passing it to re.sub. The simplest way is to change location to str(location) when using re.sub. It wouldn't hurt to do it anyways even if it's already a str.

letters_only = re.sub("[^a-zA-Z]",  # Search for all non-letters
                          " ",          # Replace all non-letters with spaces
                          str(location))

a = ['a1','b2','c3']
b = ['a1','b2','c3']
c = ['b2','a1','c3']

# if you care about order
a == b # True
a == c # False

# if you don't care about order AND duplicates
set(a) == set(b) # True
set(a) == set(c) # True

By casting a, b and c as a set, you remove duplicates and order doesn't count. Comparing sets is also much faster and more efficient than comparing lists.

You're declaring everything in the parent page. So the references to window and document are to the parent page's. If you want to do stuff to the iframe's, use iframe || iframe.contentWindow to access its window, and iframe.contentDocument || iframe.contentWindow.document to access its document.

There's a word for what's happening, possibly "lexical scope": What is lexical scope?

The only context of a scope is this. And in your example, the owner of the method is doc, which is the iframe's document. Other than that, anything that's accessed in this function that uses known objects are the parent's (if not declared in the function). It would be a different story if the function were declared in a different place, but it's declared in the parent page.

This is how I would write it:

(function () {
  var dom, win, doc, where, iframe;

  iframe = document.createElement('iframe');
  iframe.src = "javascript:false";

  where = document.getElementsByTagName('script')[0];
  where.parentNode.insertBefore(iframe, where);

  win = iframe.contentWindow || iframe;
  doc = iframe.contentDocument || iframe.contentWindow.document;

  doc.open();
  doc._l = (function (w, d) {
    return function () {
      w.vanishing_global = new Date().getTime();

      var js = d.createElement("script");
      js.src = 'test-vanishing-global.js?' + w.vanishing_global;

      w.name = "foobar";
      d.foobar = "foobar:" + Math.random();
      d.foobar = "barfoo:" + Math.random();
      d.body.appendChild(js);
    };
  })(win, doc);
  doc.write('<body onload="document._l();"></body>');
  doc.close();

The aliasing of win and doc as w and d aren't necessary, it just might make it less confusing because of the misunderstanding of scopes. This way, they are parameters and you have to reference them to access the iframe's stuff. If you want to access the parent's, you still use window and document.

I'm not sure what the implications are of adding methods to a document (doc in this case), but it might make more sense to set the _l method on win. That way, things can be run without a prefix...such as <body onload="_l();"></body>

Not really. See File input 'accept' attribute - is it useful? .

you can use UUEncoding

I found this problem too. Because centos service depend on multi-user.target for none desktop Cenots 7.2. so I delete multi-user.target from my .service file. It had missed.

Either make your friends download the runtime DLL (@Kay's answer), or compile the app with static linking.

In visual studio, go to Project tab -> properties - > configuration properties -> C/C++ -> Code Generation on runtime library choose /MTd for debug mode and /MT for release mode.

This will cause the compiler to embed the runtime into the app. The executable will be significantly bigger, but it will run without any need of runtime dlls.

If you are using Oracle 10g, you can use the DECODE function to pivot the rows into columns:

CREATE TABLE doc_tab (
  loan_number VARCHAR2(20),
  document_type VARCHAR2(20),
  document_id VARCHAR2(20)
);

INSERT INTO doc_tab VALUES('992452533663', 'Voters ID', 'XPD0355636');
INSERT INTO doc_tab VALUES('992452533663', 'Pan card', 'CHXPS5522D');
INSERT INTO doc_tab VALUES('992452533663', 'Drivers licence', 'DL-0420110141769');

COMMIT;

SELECT
    loan_number,
    MAX(DECODE(document_type, 'Voters ID', document_id)) AS voters_id,
    MAX(DECODE(document_type, 'Pan card', document_id)) AS pan_card,
    MAX(DECODE(document_type, 'Drivers licence', document_id)) AS drivers_licence
  FROM
    doc_tab
GROUP BY loan_number
ORDER BY loan_number;

Output:

LOAN_NUMBER   VOTERS_ID            PAN_CARD             DRIVERS_LICENCE    
------------- -------------------- -------------------- --------------------
992452533663  XPD0355636           CHXPS5522D           DL-0420110141769     

You can achieve the same using Oracle PIVOT clause, introduced in 11g:

SELECT *
  FROM doc_tab
PIVOT (
  MAX(document_id) FOR document_type IN ('Voters ID','Pan card','Drivers licence')
);

I have been toying with this idea too, but I was trying to achieve a slightly different behavior. My idea was to make a list which inherits itself, thus creating a data structure that by nature allows you to embed lists within lists within lists within lists...infinitely!

Implementation

//InfiniteList<T> is a list of itself...
public class InfiniteList<T> : List<InfiniteList<T>>
{
    //This is necessary to allow your lists to store values (of type T).
    public T Value { set; get; }
}

T is a generic type parameter. It is there to ensure type safety in your class. When you create an instance of InfiniteList, you replace T with the type you want your list to be populated with, or in this instance, the type of the Value property.

Example

//The InfiniteList.Value property will be of type string
InfiniteList<string> list = new InfiniteList<string>();

A "working" example of this, where T is in itself, a List of type string!

//Create an instance of InfiniteList where T is List<string>
InfiniteList<List<string>> list = new InfiniteList<List<string>>();

//Add a new instance of InfiniteList<List<string>> to "list" instance.
list.Add(new InfiniteList<List<string>>());

//access the first element of "list". Access the Value property, and add a new string to it.
list[0].Value.Add("Hello World");

A number is an integer if its modulo %1 is 0-

function isInt(n){
    return (typeof n== 'number' && n%1== 0);
}

This is only as good as javascript gets- say +- ten to the 15th.

isInt(Math.pow(2,50)+.1) returns true, as does Math.pow(2,50)+.1 == Math.pow(2,50)

The below code gets the full path, where the anchor points:

document.getElementById("aaa").href; // http://example.com/sec/IF00.html

while the one below gets the value of the href attribute:

document.getElementById("aaa").getAttribute("href"); // sec/IF00.html

First, check whether the table exists or not. Accordingly, create table if doesn't exist.

var commandStr= "If not exists (select name from sysobjects where name = 'Customer') CREATE TABLE Customer(First_Name char(50),Last_Name char(50),Address char(50),City char(50),Country char(25),Birth_Date datetime)";

using (SqlCommand command = new SqlCommand(commandStr, con))
command.ExecuteNonQuery();

You can use the * operator before an iterable to expand it within the function call. For example:

timeseries_list = [timeseries1 timeseries2 ...]
r = scikits.timeseries.lib.reportlib.Report(*timeseries_list)

(notice the * before timeseries_list)

From the python documentation:

If the syntax *expression appears in the function call, expression must evaluate to an iterable. Elements from this iterable are treated as if they were additional positional arguments; if there are positional arguments x1, ..., xN, and expression evaluates to a sequence y1, ..., yM, this is equivalent to a call with M+N positional arguments x1, ..., xN, y1, ..., yM.

This is also covered in the python tutorial, in a section titled Unpacking argument lists, where it also shows how to do a similar thing with dictionaries for keyword arguments with the ** operator.

Use this, but it's a complete solution:

[DataType(DataType.Date)]
[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:dd/MM/yyyy}")]

i didn't find who made elegant answer , that's why let me say :

Array.from(
   document.querySelectorAll('#txt1,#txt2')
).map(e => parseInt(e.value) || 0) // to avoid NaN
.reduce((a, b) => a+b, 0)

window.sum= () => _x000D_
 document.getElementById('result').innerHTML=    _x000D_
   Array.from(_x000D_
     document.querySelectorAll('#txt1,#txt2')_x000D_
   ).map(e=>parseInt(e.value)||0)_x000D_
   .reduce((a,b)=>a+b,0)

<input type="text" id="txt1" onkeyup="sum()"/>_x000D_
<input type="text" id="txt2" onkeyup="sum()"  style="margin-right:10px;"/><span id="result"></span>

You're changing the size of the list while iterating over it, which is probably not what you want and is the cause of your error.

Edit: As others have answered and commented, list comprehensions are better as a first choice and especially so in response to this question. I offered this as an alternative for that reason, and while not the best answer, it still solves the problem.

So on that note, you could also use filter, which allows you to call a function to evaluate the items in the list you don't want.

Example:

>>> l = [1,2,3,0,0,1]
>>> filter(lambda x: x > 0, l)
[1, 2, 3]

Live and learn. Simple is better, except when you need things to be complex.

Declaring objects in the smallest scope improve readability.

Performance doesn't matter for today's compilers.(in this scenario)
From a maintenance perspective, 2nd option is better.
Declare and initialize variables in the same place, in the narrowest scope possible.

As Donald Ervin Knuth told:

"We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil"

i.e) situation where a programmer lets performance considerations affect the design of a piece of code. This can result in a design that is not as clean as it could have been or code that is incorrect, because the code is complicated by the optimization and the programmer is distracted by optimizing.

Image is an equivalent to a class definition in OOP and layers are different methods and properties of that class.

Container is the actual instantiation of the image just like how an object is an instantiation or an instance of a class.

How about this solution?

// other onload attached earlier
window.onload=function() {
   alert('test');
};

tmpPreviousFunction=window.onload ? window.onload : null;

// our onload function
window.onload=function() {
   alert('another message');

   // execute previous one
   if (tmpPreviousFunction) tmpPreviousFunction();
};

Your linker (ld) obviously doesn't like the order in which make arranges the GCC arguments so you'll have to change your Makefile a bit:

CC=gcc
CFLAGS=-Wall
LDFLAGS=-lm

.PHONY: all
all: client

.PHONY: clean
clean:
    $(RM) *~ *.o client

OBJECTS=client.o
client: $(OBJECTS)
    $(CC) $(CFLAGS) $(OBJECTS) -o client $(LDFLAGS)

In the line defining the client target change the order of $(LDFLAGS) as needed.

It means that the delegate you pass is executed on the thread that created the Control object (which is the UI thread).

You need to call this method when your application is multi-threaded and you want do some UI operation from a thread other than the UI thread, because if you just try to call a method on a Control from a different thread you'll get a System.InvalidOperationException.

I know it's an old thread, but I landed here several times via Google and think no given answer is really satisfying yet. Try using one of the following functions:

EDIT: As I'm getting some likes on this old thread, I wanna share an updated solution as well (basically putting my two previous functions together and automatically deciding whether it's a bar or hbar plot):

def label_bars(ax, bars, text_format, **kwargs):
    """
    Attaches a label on every bar of a regular or horizontal bar chart
    """
    ys = [bar.get_y() for bar in bars]
    y_is_constant = all(y == ys[0] for y in ys)  # -> regular bar chart, since all all bars start on the same y level (0)

    if y_is_constant:
        _label_bar(ax, bars, text_format, **kwargs)
    else:
        _label_barh(ax, bars, text_format, **kwargs)


def _label_bar(ax, bars, text_format, **kwargs):
    """
    Attach a text label to each bar displaying its y value
    """
    max_y_value = ax.get_ylim()[1]
    inside_distance = max_y_value * 0.05
    outside_distance = max_y_value * 0.01

    for bar in bars:
        text = text_format.format(bar.get_height())
        text_x = bar.get_x() + bar.get_width() / 2

        is_inside = bar.get_height() >= max_y_value * 0.15
        if is_inside:
            color = "white"
            text_y = bar.get_height() - inside_distance
        else:
            color = "black"
            text_y = bar.get_height() + outside_distance

        ax.text(text_x, text_y, text, ha='center', va='bottom', color=color, **kwargs)


def _label_barh(ax, bars, text_format, **kwargs):
    """
    Attach a text label to each bar displaying its y value
    Note: label always outside. otherwise it's too hard to control as numbers can be very long
    """
    max_x_value = ax.get_xlim()[1]
    distance = max_x_value * 0.0025

    for bar in bars:
        text = text_format.format(bar.get_width())

        text_x = bar.get_width() + distance
        text_y = bar.get_y() + bar.get_height() / 2

        ax.text(text_x, text_y, text, va='center', **kwargs)

Now you can use them for regular bar plots:

fig, ax = plt.subplots((5, 5))
bars = ax.bar(x_pos, values, width=0.5, align="center")
value_format = "{:.1%}"  # displaying values as percentage with one fractional digit
label_bars(ax, bars, value_format)

or for horizontal bar plots:

fig, ax = plt.subplots((5, 5))
horizontal_bars = ax.barh(y_pos, values, width=0.5, align="center")
value_format = "{:.1%}"  # displaying values as percentage with one fractional digit
label_bars(ax, horizontal_bars, value_format)

I would do something like:

$(documento).on('click', '#answer', function() {
  feedback('hey there');
});

In "Path" variable removed "C:\ProgramData\Oracle\Java\javapath" and replaced it with "C:\Program Files\Java\jdk1.8.0_212\bin"

It worked for me.

Try using this:

$(".move_to").on("click", function(e){
    e.preventDefault();
    $('#contactsForm').attr('action', "/test1").submit();
});

Moving the order in which you use .preventDefault() might fix your issue. You also didn't use function(e) so e.preventDefault(); wasn't working.

Here it is working: http://jsfiddle.net/TfTwe/1/ - first of all, click the 'Check action attribute.' link. You'll get an alert saying undefined. Then click 'Set action attribute.' and click 'Check action attribute.' again. You'll see that the form's action attribute has been correctly set to /test1.

MySQL

COALESCE(field, 'default')

For example:

  SELECT
    t.id,
    COALESCE(d.field, 'default')
  FROM
     test t
  LEFT JOIN
     detail d ON t.id = d.item

Also, you can use multiple columns to check their NULL by COALESCE function. For example:

mysql> SELECT COALESCE(NULL, 1, NULL);
        -> 1
mysql> SELECT COALESCE(0, 1, NULL);
        -> 0
mysql> SELECT COALESCE(NULL, NULL, NULL);
        -> NULL

sorted return a new sorted list from the items in iterable.

CODE

import pandas as pd
df = pd.DataFrame({'A':[1,1,3,2,6,2,8]})
a = df['A'].unique()
print sorted(a)

OUTPUT

[1, 2, 3, 6, 8]

I had the same problem as above and Eclipse suggested installing:

Hint: On 64-bit systems, make sure the 32-bit libraries are installed:   
   "sudo apt-get install ia32-libs"    
or on some systems,  
   "sudo apt-get install lib32z1"   

When I tried to install ia32-libs, Ubuntu prompted to install three other packages:

$ sudo apt-get install ia32-libs  
Reading package lists... Done  
Building dependency tree         
Reading state information... Done  
Package ia32-libs is not available, but is referred to by another package.  
This may mean that the package is missing, has been obsoleted, or  
is only available from another source  
However the following packages replace it:  
  lib32z1 lib32ncurses5 lib32bz2-1.0  

E: Package 'ia32-libs' has no installation candidate  
$   
$ sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0    

With Android Studio and intellij, I also had to install the 32bit version of libstdc++6:

sudo apt-get install lib32stdc++6

Clearly, COUNT(*) and COUNT(1) will always return the same result. Therefore, if one were slower than the other it would effectively be due to an optimiser bug. Since both forms are used very frequently in queries, it would make no sense for a DBMS to allow such a bug to remain unfixed. Hence you will find that the performance of both forms is (probably) identical in all major SQL DBMSs.

ISO standards cost money, from a moderate amount (for a PDF version), to a bit more (for a book version).

While they aren't finalised however, they can usually be found online, as drafts. Most of the times the final version doesn't differ significantly from the last draft, so while not perfect, they'll suit just fine.

For readability, best to use the RFC constants in the time package (me thinks)

import "fmt" 
import "time"

func main() {
    fmt.Println(time.Now().Format(time.RFC850))
}

In windows subsystem for linux:

1. Create environment for python3:

   virtualenv --python=/usr/bin/python3 env
   

2. Activate it:

   source env/bin/activate
   

Did you try adding

'trace'=>1,

to SoapClient creation parameters and then:

var_dump($client->__getLastRequest());
var_dump($client->__getLastResponse());

to see what is going on?

You can use setTimeout or setInterval.

The difference is - setTimeout triggers your function only once, and then you must set it again. setInterval keeps triggering expression again and again, unless you tell it to stop

Easier solution will be changing this line

ft.replace(R.id.content_frame, A); to ft.add(R.id.content_frame, A);

And inside your XML layout please use

  android:background="@color/white"
  android:clickable="true"
  android:focusable="true"

Clickable means that it can be clicked by a pointer device or be tapped by a touch device.

Focusable means that it can gain the focus from an input device like a keyboard. Input devices like keyboards cannot decide which view to send its input events to based on the inputs itself, so they send them to the view that has focus.

Let me clarify two points here :

• Firstly non-default argument should not follow the default argument, it means you can't define (a = 'b',c) in function. The correct order of defining parameter in function are :
• positional parameter or non-default parameter i.e (a,b,c)
• keyword parameter or default parameter i.e (a = 'b',r= 'j')
• keyword-only parameter i.e (*args)
• var-keyword parameter i.e (**kwargs)

def example(a, b, c=None, r="w" , d=[], *ae, **ab):

(a,b) are positional parameter

(c=none) is optional parameter

(r="w") is keyword parameter

(d=[]) is list parameter

(*ae) is keyword-only

(*ab) is var-keyword parameter

so first re-arrange your parameters

• now the second thing is you have to define len1 when you are doing hgt=len1 the len1 argument is not defined when default values are saved, Python computes and saves default values when you define the function len1 is not defined, does not exist when this happens (it exists only when the function is executed)

so second remove this "len1 = hgt" it's not allowed in python.

keep in mind the difference between argument and parameters.

All you have to do is add this class to your css.

.ul-no-style { list-style: none; padding: 0; margin: 0; }

Including the padding and margin set at 0.

For Xcode 7, you have a much simpler solution. The only extra work is that you have to create a configuration plist file for exporting archive.

(Compared to Xcode 6, in the results of xcrun xcodebuild -help, -exportFormat and -exportProvisioningProfile options are not mentioned any more; the former is deleted, and the latter is superseded by -exportOptionsPlist.)

Step 1, change directory to the folder including .xcodeproject or .xcworkspace file.

cd MyProjectFolder

Step 2, use Xcode or /usr/libexec/PlistBuddy exportOptions.plist to create export options plist file. By the way, xcrun xcodebuild -help will tell you what keys you have to insert to the plist file.

Step 3, create .xcarchive file (folder, in fact) as follows(build/ directory will be automatically created by Xcode right now),

xcrun xcodebuild -scheme MyApp -configuration Release archive -archivePath build/MyApp.xcarchive

Step 4, export as .ipa file like this, which differs from Xcode6

xcrun xcodebuild -exportArchive -exportPath build/ -archivePath build/MyApp.xcarchive/ -exportOptionsPlist exportOptions.plist

Now, you get an ipa file in build/ directory. Just send it to apple App Store.

By the way, the ipa file created by Xcode 7 is much larger than by Xcode 6.

Make sure that the RSA host key and the IP of the bitbucket server is added to the 'known hosts' file. The contents should look like

bitbucket.org,xx.xx.xx.xx ssh-rsa host_key

Remember to change ownership to Jenkins for all the files in /var/lib/jenkins/.ssh/

To display a phone number with (###) ###-#### format, you can create a new HtmlHelper.

Usage

@Html.DisplayForPhone(item.Phone)

HtmlHelper Extension

public static class HtmlHelperExtensions
{
    public static HtmlString DisplayForPhone(this HtmlHelper helper, string phone)
    {
        if (phone == null)
        {
            return new HtmlString(string.Empty);
        }
        string formatted = phone;
        if (phone.Length == 10)
        {
            formatted = $"({phone.Substring(0,3)}) {phone.Substring(3,3)}-{phone.Substring(6,4)}";
        }
        else if (phone.Length == 7)
        {
            formatted = $"{phone.Substring(0,3)}-{phone.Substring(3,4)}";
        }
        string s = $"<a href='tel:{phone}'>{formatted}</a>";
        return new HtmlString(s);
    }
}

A static method means that it can be accessed without creating an object of the class, unlike public:

public class MyClass {
   // Static method
   static void myStaticMethod() {
      System.out.println("Static methods can be called without creating objects");
   }

  // Public method
  public void myPublicMethod() {
      System.out.println("Public methods must be called by creating objects");
   }

  // Main method
  public static void main(String[ ] args) {
      myStaticMethod(); // Call the static method
    // myPublicMethod(); This would output an error

    MyClass myObj = new MyClass(); // Create an object of MyClass
    myObj.myPublicMethod(); // Call the public method
  }
}

Using seeds.rb file or FactoryBot is great, but these are respectively great for fixed data structures and testing.

The seedbank gem might give you more control and modularity to your seeds. It inserts rake tasks and you can also define dependencies between your seeds. Your rake task list will have these additions (e.g.):

rake db:seed                    # Load the seed data from db/seeds.rb, db/seeds/*.seeds.rb and db/seeds/ENVIRONMENT/*.seeds.rb. ENVIRONMENT is the current environment in Rails.env.
rake db:seed:bar                # Load the seed data from db/seeds/bar.seeds.rb
rake db:seed:common             # Load the seed data from db/seeds.rb and db/seeds/*.seeds.rb.
rake db:seed:development        # Load the seed data from db/seeds.rb, db/seeds/*.seeds.rb and db/seeds/development/*.seeds.rb.
rake db:seed:development:users  # Load the seed data from db/seeds/development/users.seeds.rb
rake db:seed:foo                # Load the seed data from db/seeds/foo.seeds.rb
rake db:seed:original           # Load the seed data from db/seeds.rb

I've just had this problem i.e. checking if an object is null.
I simply use this:

if (object) {
    // Your code
}

For example:

if (document.getElementById("enterJob")) {
    document.getElementById("enterJob").className += ' current';
}

You need to use the SQL Server dynamic SQL:

DECLARE @table     NVARCHAR(128),
        @sql       NVARCHAR(MAX);

SET @table = N'tableName';

SET @sql = N'SELECT * FROM ' + @table;

Use EXEC to execute any SQL:

EXEC (@sql)

Use EXEC sp_executesql to execute any SQL:

EXEC sp_executesql @sql;

Use EXECUTE sp_executesql to execute any SQL:

EXECUTE sp_executesql @sql

just try this, it works fine in my browser:

your response writing code should be

Response.Write("<script>alert('login successful');</script>");

Hope this works

<?php
function current_url()
{
    $url      = "http://" . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
    $validURL = str_replace("&", "&amp", $url);
    return $validURL;
}
//echo "page URL is : ".current_url();

$offer_url = current_url();

?>



<?php

if ($offer_url == "checking url name") {
?> <p> hi this is manip5595 </p>

<?php
}
?>

In addition to @senderle's here, some might also be wondering how to use the functionality of multiprocessing.Pool.

The nice thing is that there is a .Pool() method to the manager instance that mimics all the familiar API of the top-level multiprocessing.

from itertools import repeat
import multiprocessing as mp
import os
import pprint

def f(d: dict) -> None:
    pid = os.getpid()
    d[pid] = "Hi, I was written by process %d" % pid

if __name__ == '__main__':
    with mp.Manager() as manager:
        d = manager.dict()
        with manager.Pool() as pool:
            pool.map(f, repeat(d, 10))
        # `d` is a DictProxy object that can be converted to dict
        pprint.pprint(dict(d))

Output:

$ python3 mul.py 
{22562: 'Hi, I was written by process 22562',
 22563: 'Hi, I was written by process 22563',
 22564: 'Hi, I was written by process 22564',
 22565: 'Hi, I was written by process 22565',
 22566: 'Hi, I was written by process 22566',
 22567: 'Hi, I was written by process 22567',
 22568: 'Hi, I was written by process 22568',
 22569: 'Hi, I was written by process 22569',
 22570: 'Hi, I was written by process 22570',
 22571: 'Hi, I was written by process 22571'}

This is a slightly different example where each process just logs its process ID to the global DictProxy object d.

A view is simply any SELECT query that has been given a name and saved in the database. For this reason, a view is sometimes called a named query or a stored query. To create a view, you use the SQL syntax:

     CREATE OR REPLACE VIEW <view_name> AS
     SELECT <any valid select query>;

Now since the HttpClient is deprecated the current working code is to use the HttpUrlConnection to create the connection and write the and read from the connection. But I preferred to use the Volley. This library is from android AOSP. I found very easy to use to make JsonObjectRequest or JsonArrayRequest

Most Simpler Way From My Side is to Add a variable in adapterPage as last Clicked Position.

in onBindViewHolder paste this code which checks for last stored position matched with loading positions Constants is the class where i declare my global variables

if(Constants.LAST_SELECTED_POSITION_SINGLE_PRODUCT == position) {

    //change the view background here
    holder.colorVariantThumb.setBackgroundResource(R.drawable.selected_background);
}

//on view click you store the position value and notifyItemRangeChanged will 
// call the onBindViewHolder and will check the condition

holder.itemView.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view){
        Constants.LAST_SELECTED_POSITION_SINGLE_PRODUCT=position;
        notifyItemRangeChanged(0, mColorVariants.size());
    } 
});

I had the same issue and for me, I tried changing the options in

• Server Locations

  and it worked.

  1. Double click on the Tomcat Server under the Servers tab in Eclipse
  2. Doing that opens a window in the editor with the top heading being Overview opens (there are 2 tabs-Overview and Modules).
  3. In that change the options under Server Locations, and give Ctrl+S (Save configurations) For me, Use Tomcat installation (takes control of Tomcat installation) worked
  4. Try starting the server and checking if localhost opens in the browser. Else select a different option.

I do not understand why that issue came up. I did search but did not find a relevant answer(Maybe I didn't use the right keywords). If someone knows why that worked, kindly share.

Thanks.

pandas has vectorized string operations, so you can just filter out the rows that contain the string you don't want:

In [91]: df = pd.DataFrame(dict(A=[5,3,5,6], C=["foo","bar","fooXYZbar", "bat"]))

In [92]: df
Out[92]:
   A          C
0  5        foo
1  3        bar
2  5  fooXYZbar
3  6        bat

In [93]: df[~df.C.str.contains("XYZ")]
Out[93]:
   A    C
0  5  foo
1  3  bar
3  6  bat

The problem you run into when setting width to 50% is the rounding of subpixels. If the width of your container is i.e. 99 pixels, a width of 50% can result in 2 containers of 50 pixels each.

Using float is probably easiest, and not such a bad idea. See this question for more details on how to fix the problem then.

If you don't want to use float, try using a width of 49%. This will work cross-browser as far as I know, but is not pixel-perfect..

html:

<div id="a">A</div>
<div id="b">B</div>

css:

#a, #b {
    width: 49%;
    display: inline-block; 
}
#a {background-color: red;}
#b {background-color: blue;}

Instead of Str(RequestID), try convert(varchar(38), RequestID)

Short Answer: After installing "Code Runner" extension, you just have to right-click the selected part of code you wish to execute and see it in the Output Tab.

I have done some testing and using CSS3 to redefine the scrollbars works and you get to keep your Overflow:scroll; or Overflow:auto

I ended up with something like this...

::-webkit-scrollbar {
    width: 15px;
    height: 15px;
    border-bottom: 1px solid #eee; 
    border-top: 1px solid #eee;
}
::-webkit-scrollbar-thumb {
    border-radius: 8px;
    background-color: #C3C3C3;
    border: 2px solid #eee;
}

::-webkit-scrollbar-track {
    -webkit-box-shadow: inset 0 0 6px rgba(0,0,0,0.2); 
} 

The only down side which I have not yet been able to figure out is how to interact with the scrollbars on iProducts but you can interact with the content to scroll it

The else-clause is executed when the while-condition evaluates to false.

From the documentation:

The while statement is used for repeated execution as long as an expression is true:

while_stmt ::=  "while" expression ":" suite
                ["else" ":" suite]

This repeatedly tests the expression and, if it is true, executes the first suite; if the expression is false (which may be the first time it is tested) the suite of the else clause, if present, is executed and the loop terminates.

A break statement executed in the first suite terminates the loop without executing the else clause’s suite. A continue statement executed in the first suite skips the rest of the suite and goes back to testing the expression.

With a simple JSON object, you don't need jQuery:

for (var i in json) {
   for (var j in json[i]) {
     console.log(json[i][j]);
   }
}

I didn't want a reference to EF in my application project (or to manually copy anything) so I added this to my EF project's Post-build events:

cp $(TargetDir)EntityFramework.SqlServer.dll $(SolutionDir){your-main-bin-folder}

Maybe it is time to start revising this answer? Personally I would vote for setActive() and unsetActive() (alternatives can be setUnActive(), notActive(), disable(), etc. depending on context) since "setActive" implies you activate it at all times, which you don't. It's kind of counter intuitive to say "setActive" but actually remove the active state.

Another problem is, you can can not listen to specifically a SetActive event in a CQRS way, you would need to listen to a 'setActiveEvent' and determine inside that listener wether is was actually set active or not. Or of course determine which event to call when calling setActive() but that then goes against the Separation of Concerns principle.

A good read on this is the FlagArgument article by Martin Fowler: http://martinfowler.com/bliki/FlagArgument.html

However, I come from a PHP background and see this trend being adopted more and more. Not sure how much this lives with Java development.

//Check if Safari
  function isSafari() {
      return /^((?!chrome).)*safari/i.test(navigator.userAgent);
  }
//Check if MAC
     if(navigator.userAgent.indexOf('Mac')>1){
        alert(isSafari());
     }

If you are looking for the executable that npm installed, maybe because you would like to put it in your PATH, you can simply do

npm bin

or

npm bin -g

You can also provide a negative number as an argument to the round method to round to the nearest multiple of 10, 100 and so on.

# Round to the nearest multiple of 10. 
12.3453.round(-1)       # Output: 10

# Round to the nearest multiple of 100. 
124.3453.round(-2)      # Output: 100

<?php
$stop_date = '2009-09-30 20:24:00';
echo 'date before day adding: ' . $stop_date; 
$stop_date = date('Y-m-d H:i:s', strtotime($stop_date . ' +1 day'));
echo 'date after adding 1 day: ' . $stop_date;
?>

For PHP 5.2.0+, you may also do as follows:

$stop_date = new DateTime('2009-09-30 20:24:00');
echo 'date before day adding: ' . $stop_date->format('Y-m-d H:i:s'); 
$stop_date->modify('+1 day');
echo 'date after adding 1 day: ' . $stop_date->format('Y-m-d H:i:s');

This way doesn't work now:

 btn.titleLabel?.font = UIFont(name: "Helvetica", size:12)

This works:

 btn.titleLabel?.font = UIFont.init(name: "Helvetica", size:12)

So, 10 years later this is still a thing :)

I've tried every answer on this page (ATOW)
and also some ILGenerator powered solutions (FastMember and Fast.Reflection).
But a compiled Lambda Expression seems to be the fastest.
At least for my use cases (on .Net Core 2.2).

This is what I am using for now:

public static class EnumerableExtensions {

    internal static Func<TClass, object> CompileGetter<TClass>(string propertyName) {
        var param = Expression.Parameter(typeof(TClass));
        var body = Expression.Convert(Expression.Property(param, propertyName), typeof(object));
        return Expression.Lambda<Func<TClass, object>>(body,param).Compile();
    }     

    public static DataTable ToDataTable<T>(this IEnumerable<T> collection) {
        var dataTable = new DataTable();
        var properties = typeof(T)
                        .GetProperties(BindingFlags.Public | BindingFlags.Instance)
                        .Where(p => p.CanRead)
                        .ToArray();

        if (properties.Length < 1) return null;
        var getters = new Func<T, object>[properties.Length];

        for (var i = 0; i < properties.Length; i++) {
            var columnType = Nullable.GetUnderlyingType(properties[i].PropertyType) ?? properties[i].PropertyType;
            dataTable.Columns.Add(properties[i].Name, columnType);
            getters[i] = CompileGetter<T>(properties[i].Name);
        }

        foreach (var row in collection) {
            var dtRow = new object[properties.Length];
            for (var i = 0; i < properties.Length; i++) {
                dtRow[i] = getters[i].Invoke(row) ?? DBNull.Value;
            }
            dataTable.Rows.Add(dtRow);
        }

        return dataTable;
    }
}

Only works with properties (not fields) but it works on Anonymous Types.

Alter table Hotels 
Add  
{ 
 HasPhotoInReadyStorage  bit, 
 HasPhotoInWorkStorage  bit, 
 HasPhotoInMaterialStorage bit, 
 HasHotelPhotoInReadyStorage  bit, 
 HasHotelPhotoInWorkStorage  bit, 
 HasHotelPhotoInMaterialStorage bit, 
 HasReporterData  bit, 
 HasMovieInReadyStorage  bit, 
 HasMovieInWorkStorage  bit, 
 HasMovieInMaterialStorage bit 
}; 

Above you are using {, }.

Also, you are missing commas:

ALTER TABLE Regions 
ADD ( HasPhotoInReadyStorage  bit, 
 HasPhotoInWorkStorage  bit, 
 HasPhotoInMaterialStorage bit <**** comma needed here
 HasText  bit); 

You need to remove the brackets and make sure all columns have a comma where necessary.

A work-around for people who are experiencing a bug like Nathan:

The on-the-fly compiler seems to have a problem with this Extension Method error... adding static didn't help me either.

I'd like to know what causes the bug?

But the work-around is to write a new Extension class (not nested) even in same file and re-build.

Figured that this thread is getting enough views that it's worth passing on (the limited) solution I found. Most people probably tried adding 'static' before google-ing for a solution! and I didn't see this work-around fix anywhere else.

We have tried custom search box with the pasted snippet. This code will useful for all kind of TextFiled decoration in Flutter. Hope this snippet will helpful for others.

Container(
        margin: EdgeInsets.fromLTRB(0.0, 10.0, 0.0, 10.0),
        child:  new Theme(
          data: new ThemeData(
           hintColor: Colors.white,
            primaryColor: Colors.white,
            primaryColorDark: Colors.white,
          ),
          child:Padding(
          padding: EdgeInsets.all(10.0),
          child: TextField(
            style: TextStyle(color: Colors.white),
            onChanged: (value) {
              filterSearchResults(value);
            },
            controller: editingController,
            decoration: InputDecoration(
                labelText: "Search",
                hintText: "Search",
                prefixIcon: Icon(Icons.search,color: Colors.white,),
                enabled: true,
                enabledBorder: OutlineInputBorder(
                  borderSide: BorderSide(color: Colors.white),
                    borderRadius: BorderRadius.all(Radius.circular(25.0))),
                border: OutlineInputBorder(
                    borderSide: const BorderSide(color: Colors.white, width: 0.0),
                    borderRadius: BorderRadius.all(Radius.circular(25.0)))),
          ),
        ),
        ),
      ),

Note that you may want to do null checks on them as well prior to doing your .equals or .equalsIgnoreCase.

A null String object can not call an equals method.

ie:

public boolean areStringsSame(String str1, String str2)
{
    if (str1 == null && str2 == null)
        return true;
    if (str1 == null || str2 == null)
        return false;

    return str1.equalsIgnoreCase(str2);
}

Resize using helper methods and start-repeat-end handlers like this:

resize(
    view1,
    1.0f,
    0.0f,
    1.0f,
    0.0f,
    0.0f,
    0.0f,
    150,
    null,
    null,
    null);

  return null;
}

Not all collections have indexes. For instance, I can use a Dictionary with foreach (and iterate through all the keys and values), but I can't write get at individual elements using dictionary[0], dictionary[1] etc.

If I did want to iterate through a dictionary and keep track of an index, I'd have to use a separate variable that I incremented myself.

You can use _ _getitem__(key) function.

>>> iterable = ('A', 'B', 'C', 'D', 'E')
>>> key = 4
>>> iterable.__getitem__(key)
'E'

For what it's worth, my groovy spike seems to work with both UTF-8 and ISO-8859-1 character encodings. Not sure what will happen when a non zxing decoder tries to decode the UTF-8 encoded image though... probably varies depending on the device.

        Result result = new MultiFormatReader().decode(binaryBitmap, hints)

        result.getText()        
    }

}

When use method delete in form then must have to set route delete

Route::delete("empresas/eliminar/{id}", "CompaniesController@delete");

you can do like this. imageuri can be converted into string like this.

intent.putExtra("imageUri", imageUri.toString());

Every instance of View calls getViewTreeObserver(). Now when holding an instance of ViewTreeObserver, you can add an OnScrollChangedListener() to it using the method addOnScrollChangedListener().

You can see more information about this class here.

It lets you be aware of every scrolling event - but without the coordinates. You can get them by using getScrollY() or getScrollX() from within the listener though.

scrollView.getViewTreeObserver().addOnScrollChangedListener(new OnScrollChangedListener() {
    @Override
    public void onScrollChanged() {
        int scrollY = rootScrollView.getScrollY(); // For ScrollView
        int scrollX = rootScrollView.getScrollX(); // For HorizontalScrollView
        // DO SOMETHING WITH THE SCROLL COORDINATES
    }
});

I was also stuck on the same kind of problem and I followed the simple steps below.

Just get the exact url of the file to which you want to copy, for example:

http://www.test.com/test.txt (file to copy)

Then pass the exact absolute folder path with filename where you do want to write that file.

1. If you are on a Windows machine then d:/xampp/htdocs/upload/test.txt

2. If you are on a Linux machine then /var/www/html/upload/test.txt

You can get the document root with the PHP function $_SERVER['DOCUMENT_ROOT'].

import pickle

intArray = [i for i in range(1,100)]
output = open('data.pkl', 'wb')
pickle.dump(intArray, output)
output.close()

Test your pickle quickly. pickle is a part of standard python library and available by default.
