What worked for me is to nullify the listeners on the viewHolder when the view is going to be recycled (onViewRecycled):

 override fun onViewRecycled(holder: AttendeeViewHolder) {
            super.onViewRecycled(holder)
            holder.itemView.hasArrived.setOnCheckedChangeListener(null);
            holder.itemView.edit.setOnClickListener { null }
        }

Probably, you need to insert schema identifier here:

in.addValue("po_system_users", null, OracleTypes.ARRAY, "your_schema.T_SYSTEM_USER_TAB");

If you use Cristian's solution, you'll need to inject the EntityManager into your FormType class. Here is a simplified example:

class EntityType extends AbstractType{
    public function __construct($em) {
        $this->em = $em;
    }

    public function buildForm(FormBuilderInterface $builder, array $options){
         $builder
             ->add('MyEntity', 'entity', array(
                     'class' => 'AcmeDemoBundle:Entity',
                     'property' => 'name',
                     'query_builder' => function(EntityRepository $er) {
                         return $er->createQueryBuilder('e')
                             ->orderBy('e.name', 'ASC');
                     },
                     'data' => $this->em->getReference("AcmeDemoBundle:Entity", 3)
        ));
    }
}

And your controller:

 // ...    

 $form = $this->createForm(new EntityType($this->getDoctrine()->getManager()), $entity);

// ...

From Doctrine Docs:

The method EntityManager#getReference($entityName, $identifier) lets you obtain a reference to an entity for which the identifier is known, without loading that entity from the database. This is useful, for example, as a performance enhancement, when you want to establish an association to an entity for which you have the identifier.

This is possibly the most awesome stack overflow question/answer(s) ever. I love Sam's/Brad's solutions above. Thought I'd chime in with the async version that I implemented:

function loadRoutes(folder){
    if (!folder){
        folder = __dirname + '/routes/';
    }

    fs.readdir(folder, function(err, files){
        var l = files.length;
        for (var i = 0; i < l; i++){
            var file = files[i];
            fs.stat(file, function(err, stat){
                if (stat && stat.isDirectory()){
                    loadRoutes(folder + '/' + file + '/');
                } else {
                    var dot = file.lastIndexOf('.');
                    if (file.substr(dot + 1) === 'js'){
                        var name = file.substr(0, dot);

                        // I'm also passing argv here (from optimist)
                        // so that I can easily enable debugging for all
                        // routes.
                        require(folder + name)(app, argv);
                    }
                }
            });
        }
    });
}

My directory structure is a little different. I typically define routes in app.js (in the root directory of the project) by require-ing './routes'. Consequently, I'm skipping the check against index.js because I want to include that one as well.

EDIT: You can also put this in a function and call it recursively (I edited the example to show this) if you want to nest your routes in folders of arbitrary depth.

You need to return the validating function. Something like:

onsubmit="return validateForm();"

Then the validating function should return false on errors. If everything is OK return true. Remember that the server has to validate as well.

Try this:

 window.location.href = "http://www.gorissen.info/Pierre/maps/googleMapLocation.php?lat="+elemA+"&lon="+elemB+"&setLatLon=Set";

To put a variable in a string enclose the variable in quotes and addition signs like this:

var myname = "BOB";
var mystring = "Hi there "+myname+"!"; 

Just remember that one rule!

I would recommend virtualenvwrapper as well. It works wonders for me and how I always have problems with activating. http://virtualenvwrapper.readthedocs.org/en/latest/

In my case I had to wait for a user interaction, so I set a click or touchend listener.

const isMobile = navigator.maxTouchPoints || "ontouchstart" in document.documentElement;

function play(){
    audioEl.play()
}


document.body.addEventListener(isMobile ? "touchend" : "click", play, { once: true });

You could add some logging to the Global.asax in Session_Start and Application_Start to track what's going on with the user's Session and the Application as a whole.

Also, watch out of you're running in Web Farm mode (multiple IIS threads defined in the application pool) or load balancing because the user can end up hitting a different server that does not have the same memory. If this is the case, you can switch the Session mode to SQL Server.

An even simpler solution to the above:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true">
        <color android:color="@color/semitransparent_white" />
    </item>
    <item>
        <color android:color="@color/transparent" />
    </item>
</selector>

Save that in the drawable folder and you're good to go.

Make the file accessible to the Authenticated Users group. Right click your virtual directory and give the group read/write access to Authenticated Users.

I faced issue on windows 10 machine.

Instead of using fake dates like 0000-00-00 00:00:00 or 0001-01-01 00:00:00 (the latter should be accepted as it is a valid date), change your database schema, to allow NULL values.

ALTER TABLE table_name MODIFY COLUMN date TIMESTAMP NULL

Assuming your date column is an actual MySQL date column:

SELECT * FROM jokes WHERE date > DATE_SUB(NOW(), INTERVAL 1 DAY) ORDER BY score DESC;        
SELECT * FROM jokes WHERE date > DATE_SUB(NOW(), INTERVAL 1 WEEK) ORDER BY score DESC;
SELECT * FROM jokes WHERE date > DATE_SUB(NOW(), INTERVAL 1 MONTH) ORDER BY score DESC;

<?php  
    $args = array(
        'post_type'      => 'product',
        'posts_per_page' => 10,
        'product_cat'    => 'hoodies'
    );

    $loop = new WP_Query( $args );

    while ( $loop->have_posts() ) : $loop->the_post();
        global $product;
        echo '<br /><a href="'.get_permalink().'">' . woocommerce_get_product_thumbnail().' '.get_the_title().'</a>';
    endwhile;

    wp_reset_query();
?>

This will list all product thumbnails and names along with their links to product page. change the category name and posts_per_page as per your requirement.

In addition to bcrypt and PBKDF2 mentioned in other answers, I would recommend looking at scrypt

MD5 and SHA-1 are not recommended as they are relatively fast thus using "rent per hour" distributed computing (e.g. EC2) or a modern high end GPU one can "crack" passwords using brute force / dictionary attacks in relatively low costs and reasonable time.

If you must use them, then at least iterate the algorithm a predefined significant amount of times (1000+).

int ot = getResources().getConfiguration().orientation;
switch(ot)
        {

        case  Configuration.ORIENTATION_LANDSCAPE:

            Log.d("my orient" ,"ORIENTATION_LANDSCAPE");
        break;
        case Configuration.ORIENTATION_PORTRAIT:
            Log.d("my orient" ,"ORIENTATION_PORTRAIT");
            break;

        case Configuration.ORIENTATION_SQUARE:
            Log.d("my orient" ,"ORIENTATION_SQUARE");
            break;
        case Configuration.ORIENTATION_UNDEFINED:
            Log.d("my orient" ,"ORIENTATION_UNDEFINED");
            break;
            default:
            Log.d("my orient", "default val");
            break;
        }

Try:

=ArrayFormula(QUERY(A:A&{"",""};"select Col1, count(Col2) where Col1 != '' group by Col1 label count(Col2) 'Count'";1))

22/07/2014 Some time in the last month, Sheets has started supporting more flexible concatenation of arrays, using an embedded array. So the solution may be shortened slightly to:

=QUERY({A:A,A:A},"select Col1, count(Col2) where Col1 != '' group by Col1 label count(Col2) 'Count'",1)

If you're using Java 8, you can use Lambda expressions to match.

import java.util.Optional;
import java.util.function.Predicate;

import org.hamcrest.BaseMatcher;
import org.hamcrest.Description;

public class LambdaMatcher<T> extends BaseMatcher<T>
{
    private final Predicate<T> matcher;
    private final Optional<String> description;

    public LambdaMatcher(Predicate<T> matcher)
    {
        this(matcher, null);
    }

    public LambdaMatcher(Predicate<T> matcher, String description)
    {
        this.matcher = matcher;
        this.description = Optional.ofNullable(description);
    }

    @SuppressWarnings("unchecked")
    @Override
    public boolean matches(Object argument)
    {
        return matcher.test((T) argument);
    }

    @Override
    public void describeTo(Description description)
    {
        this.description.ifPresent(description::appendText);
    }
}

Example call

@Test
public void canFindEmployee()
{
    Employee employee = new Employee("John");
    company.addEmployee(employee);

    verify(mockedDal).registerEmployee(argThat(new LambdaMatcher<>(e -> e.getName()
                                                                         .equals(employee.getName()))));
}

Swift 3, xcode 8.1

You can use small extension to place UIActivityIndicatorView in the centre of UIView and inherited UIView classes:

Code

extension UIActivityIndicatorView {

    convenience init(activityIndicatorStyle: UIActivityIndicatorViewStyle, color: UIColor, placeInTheCenterOf parentView: UIView) {
        self.init(activityIndicatorStyle: activityIndicatorStyle)
        center = parentView.center
        self.color = color
        parentView.addSubview(self)
    }
}

How to use

let activityIndicator = UIActivityIndicatorView(activityIndicatorStyle: .whiteLarge, color: .gray,  placeInTheCenterOf: view)
activityIndicator.startAnimating()

Full Example

In this example UIActivityIndicatorView placed in the centre of the ViewControllers view:

import UIKit

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        let activityIndicator = UIActivityIndicatorView(activityIndicatorStyle: .whiteLarge, color: .gray,  placeInTheCenterOf: view)
        activityIndicator.startAnimating()
    }
}

extension UIActivityIndicatorView {

    convenience init(activityIndicatorStyle: UIActivityIndicatorViewStyle, color: UIColor, placeInTheCenterOf parentView: UIView) {
        self.init(activityIndicatorStyle: activityIndicatorStyle)
        center = parentView.center
        self.color = color
        parentView.addSubview(self)
    }
}

To sort by a property in the object, you have to specify a comparer or a method to get that property.

Using the List.Sort method:

theList.Sort(Function(x, y) x.age.CompareTo(y.age))

Using the OrderBy extension method:

theList = theList.OrderBy(Function(x) x.age).ToList()

Obviously @Lasse solution is right, but there's another way to solve your problem: T-SQL operator LIKE defines the optional ESCAPE clause, that lets you declare a character which will escape the next character into the pattern.

For your case, the following WHERE clauses are equivalent:

WHERE username LIKE '%[_]d';            -- @Lasse solution
WHERE username LIKE '%$_d' ESCAPE '$';
WHERE username LIKE '%^_d' ESCAPE '^';

This method takes one Function as an argument, this function accepts one parameter T as an input argument and return one stream of parameter R as a return value. When this function is applied on each element of this stream, it produces a stream of new values. All the elements of these new streams generated by each element are then copied to a new stream, which will be a return value of this method.

In case anybody has an issue with setting datetimepicker control to blank during the form load event, and then show the current date as needed, here is an example:

MAKE SURE THAT CustomFormat = " " has same number of spaces (at least one space) in both methods

Private Sub setDateTimePickerBlank(ByVal dateTimePicker As DateTimePicker)    

    dateTimePicker.Visible = True
    dateTimePicker.Format = DateTimePickerFormat.Custom
    dateTimePicker.CustomFormat = "    " 
End Sub


Private Sub dateTimePicker_MouseHover(ByVal sender As Object, ByVal e As 
                    System.EventArgs) Handles dateTimePicker.MouseHover

    Dim dateTimePicker As DateTimePicker = CType(sender, DateTimePicker)
    If dateTimePicker.Text = "    " Then
        dateTimePicker.Text = Format(DateTime.Now, "MM/dd/yyyy")
    End If
End Sub

Here in this case, we are having 3 parameter's in the Method namely ModelandView.
According to this question, the first parameter is easily understood. It represents the View which will be displayed to the client.
The other two parameters are just like The Pointer and The Holder
Hence you can sum it up like this

ModelAndView(View, Pointer, Holder);

The Pointer just points the information in the The Holder

When the Controller binds the View with this information, then in the said process, you can use The Pointer in the JSP page to access the information stored in The Holder to display that respected information to the client.
Here is the visual depiction of the respected process.

return new ModelAndView("welcomePage", "WelcomeMessage", message);

Because Mac OS has not been mentioned I will add that I had the same problem on OS X Yosemite, the solution I found was to do brew install graphviz

This solved the problem, not sure if I shouldn't have just edited one of the other answers in this list, because they all seem to be the same answer, just install an official package in addition to the Python Library.

To summarise all of these answers:

1. Add a single top-level field called // that contains a comment string. This works, but it sucks because you can't put comments near the thing they are commenting on.

2. Add multiple top-level fields starting with //, e.g. //dependencies that contains a comment string. This is better, but it still only allows you to make top-level comments. You can't comment individual dependencies.

3. Add echo commands to your scripts. This works, but it sucks because you can only use it in scripts.

These solutions are also all not very readable. They add a ton of visual noise and IDEs will not syntax highlight them as comments.

I think the only reasonable solution is to generate the package.json from another file. The simplest way is to write your JSON as JavaScript and use Node.js to write it to package.json. Save this file as package.json.mjs, chmod +x it, and then you can just run it to generate your package.json.

#!/usr/bin/env node

import { writeFileSync } from "fs";

const config = {
  // TODO: Think of better name.
  name: "foo",
  dependencies: {
    // Bar 2.0 does not work due to bug 12345.
    bar: "^1.2.0",
  },
  // Look at these beautify comments. Perfectly syntax highlighted, you
  // can put them anywhere and there no risk of some tool removing them.
};

writeFileSync("package.json", JSON.stringify({
    "//": "This file is \x40generated from package.json.mjs; do not edit.",
    ...config
  }, null, 2));

It uses the // key to warn people from editing it. \x40generated is deliberate. It turns into @generated in package.json and means some code review systems will collapse that file by default.

It's an extra step in your build system, but it beats all of the other hacks here.

Like this:

#include <vector>

// ...

std::vector<std::vector<int>> A(dimension, std::vector<int>(dimension));

(Pre-C++11 you need to leave whitespace between the angled brackets.)

If you are in need of the shadows properly to be applied then you have to do the following.

Consider this view, defined with a background drawable:

<TextView
    android:id="@+id/myview"
    ...
    android:elevation="2dp"
    android:background="@drawable/myrect" />

The background drawable is defined as a rectangle with rounded corners:

<shape xmlns:android="http://schemas.android.com/apk/res/android"
       android:shape="rectangle">
    <solid android:color="#42000000" />
    <corners android:radius="5dp" />
</shape>

This is the recomended way of appying shadows check this out https://developer.android.com/training/material/shadows-clipping.html#Shadows

I have found that the best place is in NgAfterViewChecked(). I tried to execute code that would scroll to an ng-accordion panel when the page was loaded. I tried putting the code in NgAfterViewInit() but it did not work there (NPE). The problem was that the element had not been rendered yet. There is a problem with putting it in NgAfterViewChecked(). NgAfterViewChecked() is called several times as the page is rendered. Some calls are made before the element is rendered. This means a check for null may be required to guard the code from NPE. I am using Angular 8.

From search engines, I ended up on this topic for non-json posting data with fetch, so thought I would add this.

For non-json you don't have to use form data. You can simply set the Content-Type header to application/x-www-form-urlencoded and use a string:

fetch('url here', {
    method: 'POST',
    headers: {'Content-Type':'application/x-www-form-urlencoded'}, // this line is important, if this content-type is not set it wont work
    body: 'foo=bar&blah=1'
});

An alternative way to build that body string, rather then typing it out as I did above, is to use libraries. For instance the stringify function from query-string or qs packages. So using this it would look like:

import queryString from 'query-string'; // import the queryString class

fetch('url here', {
    method: 'POST',
    headers: {'Content-Type':'application/x-www-form-urlencoded'}, // this line is important, if this content-type is not set it wont work
    body: queryString.stringify({for:'bar', blah:1}) //use the stringify object of the queryString class
});

Swift 3.0 // create attributed string

Define attributes like

let attributes = [NSAttributedStringKey.font : UIFont.init(name: "Avenir-Medium", size: 13.0)]

For applications such as Squirrel SQL Client (http://squirrel-sql.sourceforge.net/) version 4 you can set "serverTimezone" under "driver properties" to GMT+1 (example of timezone "Europe/Vienna).

Option 1:

NSString *haystack = @"value:hello World:value";
NSString *haystackPrefix = @"value:";
NSString *haystackSuffix = @":value";
NSRange needleRange = NSMakeRange(haystackPrefix.length,
                                  haystack.length - haystackPrefix.length - haystackSuffix.length);
NSString *needle = [haystack substringWithRange:needleRange];
NSLog(@"needle: %@", needle); // -> "hello World"

Option 2:

NSRegularExpression *regex = [NSRegularExpression regularExpressionWithPattern:@"^value:(.+?):value$" options:0 error:nil];
NSTextCheckingResult *match = [regex firstMatchInString:haystack options:NSAnchoredSearch range:NSMakeRange(0, haystack.length)];
NSRange needleRange = [match rangeAtIndex: 1];
NSString *needle = [haystack substringWithRange:needleRange];

This one might be a bit over the top for your rather trivial case though.

Option 3:

NSString *needle = [haystack componentsSeparatedByString:@":"][1];

This one creates three temporary strings and an array while splitting.

All snippets assume that what's searched for is actually contained in the string.

I have also read that for some servers one for example needs only annotate persistence contexts, but in some servers, the injection should be done manually.

To revert the revert without screwing up your workflow too much:

• Create a local trash copy of develop
• Revert the revert commit on the local copy of develop
• Merge that copy into your feature branch, and push your feature branch to your git server.

Your feature branch should now be able to be merged as normal when you're ready for it. The only downside here is that you'll a have a few extra merge/revert commits in your history.

You may enjoy package friendlyeval which presents a simplified tidy eval API and documentation for newer/casual dplyr users.

You are creating strings that you wish mutate to treat as column names. So using friendlyeval you could write:

multipetal <- function(df, n) {
  varname <- paste("petal", n , sep=".")
  df <- mutate(df, !!treat_string_as_col(varname) := Petal.Width * n)
  df
}

for(i in 2:5) {
  iris <- multipetal(df=iris, n=i)
}

Which under the hood calls rlang functions that check varname is legal as column name.

friendlyeval code can be converted to equivalent plain tidy eval code at any time with an RStudio addin.

You'll see people using the Timer class to do this. Unfortunately, it isn't always accurate. Your best bet is to get the system time when the user enters input, calculate a target system time, and check if the system time has exceeded the target system time. If it has, then break out of the loop.

If you want to keep the multi dimensional array, one should nest the array brackets. see example below where one is added to every element.

>>> a = [[1, 2], [3, 4]]

>>> [[col +1 for col in row] for row in a]
[[2, 3], [4, 5]]

>>> [col +1 for row in a for col in row]
[2, 3, 4, 5]

Your solution did not work in Python 2.7. There was an error while checking for the order of the x elements. I had to change to code to this to get it to work:

from bisect import bisect_left
class Interpolate(object):
    def __init__(self, x_list, y_list):
        if any([y - x <= 0 for x, y in zip(x_list, x_list[1:])]):
            raise ValueError("x_list must be in strictly ascending order!")
        x_list = self.x_list = map(float, x_list)
        y_list = self.y_list = map(float, y_list)
        intervals = zip(x_list, x_list[1:], y_list, y_list[1:])
        self.slopes = [(y2 - y1)/(x2 - x1) for x1, x2, y1, y2 in intervals]
    def __getitem__(self, x):
        i = bisect_left(self.x_list, x) - 1
        return self.y_list[i] + self.slopes[i] * (x - self.x_list[i])

You can use pathlib.

For Python 3.5 and above:

from pathlib import Path
contents = Path(file_path).read_text()

For older versions of Python use pathlib2:

$ pip install pathlib2

Then:

from pathlib2 import Path
contents = Path(file_path).read_text()

This is the actual read_text implementation:

def read_text(self, encoding=None, errors=None):
    """
    Open the file in text mode, read it, and close the file.
    """
    with self.open(mode='r', encoding=encoding, errors=errors) as f:
        return f.read()

try this

function global_func(...args){
  for(let i of args){
    console.log(i)
  }
}


global_func('task_name', 'action', [{x: 'x'},{x: 'x'}], {x: 'x'}, ['x1','x2'], 1, null, undefined, false, true)




//task_name
//action
//(2) [{...},
//    {...}]
//    {
//        x:"x"
//    }
//(2) [
//        "x1",
//        "x2"
//    ]
//1
//null
//undefined
//false
//true
//func

You could also expose the directive's controller to the parent scope, like ngForm with name attribute does: http://docs.angularjs.org/api/ng.directive:ngForm

Here you could find a very basic example how it could be achieved http://plnkr.co/edit/Ps8OXrfpnePFvvdFgYJf?p=preview

In this example I have myDirective with dedicated controller with $clear method (sort of very simple public API for the directive). I can publish this controller to the parent scope and use call this method outside the directive.

After :

sockfd = socket(AF_INET, SOCK_STREAM, 0);
if (sockfd < 0) 
    error("ERROR opening socket");

You can add (with standard C99 compound literal support) :

if (setsockopt(sockfd, SOL_SOCKET, SO_REUSEADDR, &(int){1}, sizeof(int)) < 0)
    error("setsockopt(SO_REUSEADDR) failed");

Or :

int enable = 1;
if (setsockopt(sockfd, SOL_SOCKET, SO_REUSEADDR, &enable, sizeof(int)) < 0)
    error("setsockopt(SO_REUSEADDR) failed");

If you include the following code at the top of your script, matplotlib will run inline when in an IPython environment (like jupyter, hydrogen atom plugin...), and it will still work if you launch the script directly via command line (matplotlib won't run inline, and the charts will open in a pop-ups as usual).

from IPython import get_ipython
ipy = get_ipython()
if ipy is not None:
    ipy.run_line_magic('matplotlib', 'inline')

Take caution not to overuse the section tag as a replacement for a div element. A section tag should define a significant region within the context of the body. Semantically, HTML5 encourages us to define our document as follows:

<html>_x000D_
<head></head>_x000D_
<body>_x000D_
    <header></header>_x000D_
    <section>_x000D_
        <h1></h1>_x000D_
        <div>_x000D_
            <span></span>_x000D_
        </div>_x000D_
        <div></div>_x000D_
    </section>_x000D_
    <footer></footer>_x000D_
</body>_x000D_
</html>

This strategy allows web robots and automated screen readers to better understand the flow of your content. This markup clearly defines where your major page content is contained. Of course, headers and footers are often common across hundreds if not thousands of pages within a website. The section tag should be limited to explain where the unique content is contained. Within the section tag, we should then continue to markup and control the content with HTML tags which are lower in the hierarchy, like h1, div, span, etc.

In most simple pages, there should only be a single section tag, not multiple ones. Please also consider also that there are other interesting HTML5 tags which are similar to section. Consider using article, summary, aside and others within your document flow. As you can see, these tags further enhance our ability to define the major regions of the HTML document.

UPDATE Table
SET DateColumn=GETDATE()
WHERE UserID=@UserID

If you're inserting into a table, and will always need to put the current date, I would recommend setting GETDATE() as the default value for that column, and don't allow NULLs

If you need a random number in the range [double.MinValue; double.MaxValue]

// Because of:
double.MaxValue - double.MinValue == double.PositiveInfinity

// This will be equals to NaN or PositiveInfinity
random.NextDouble() * (double.MaxValue - double.MinValue)

Use instead:

public static class RandomExtensions
{
    public static double NextDoubleInMinMaxRange(this Random random)
    {
        var bytes = new byte[sizeof(double)];
        var value = default(double);
        while (true)
        {
            random.NextBytes(bytes);
            value = BitConverter.ToDouble(bytes, 0);
            if (!double.IsNaN(value) && !double.IsInfinity(value))
                return value;
        }
    }
}

Updated answer that covers most cases

curl -H "Access-Control-Request-Method: GET" -H "Origin: http://localhost" --head http://www.example.com/

1. Replace http://www.example.com/ with URL you want to test.
2. If response includes Access-Control-Allow-* then your resource supports CORS.

Rationale for alternative answer

I google this question every now and then and the accepted answer is never what I need. First it prints response body which is a lot of text. Adding --head outputs only headers. Second when testing S3 URLs we need to provide additional header -H "Access-Control-Request-Method: GET".

Hope this will save time.

Try with conditions.

$id = 1;
Post::with(array('user'=>function($query) use ($id){
    $query->where('id','=',$id);
    $query->select('id','username');
}))->get();

MSDeploy can migrate all content, config, etc. that is what the IIS team recommends. http://www.iis.net/extensions/WebDeploymentTool

To create a package, run the following command (replace Default Web Site with your web site name):

msdeploy.exe -verb:sync -source:apphostconfig="Default Web Site" -dest:package=c:\dws.zip > DWSpackage7.log

To restore the package, run the following command:

msdeploy.exe -verb:sync -source:package=c:\dws.zip -dest:apphostconfig="Default Web Site" > DWSpackage7.log

I had the same issue. Solution for me was using the stringified output as input to parsing the JSON. this worked for me. hope its useful to you

var x =JSON.parse(JSON.stringify(obj));
console.log(x.property_actually_now_defined);

Just ask it for the objectForKey:@"b". If it returns nil, no object is set at that key.

if ([xyz objectForKey:@"b"]) {
    NSLog(@"There's an object set for key @\"b\"!");
} else {
    NSLog(@"No object set for key @\"b\"");
}

Edit: As to your edited second question, it's simply NSUInteger mCount = [xyz count];. Both of these answers are documented well and easily found in the NSDictionary class reference ([1] [2]).

It's useful to work with Deferred Object in this case, and return promise:

function readImage(inputElement) {
    var deferred = $.Deferred();

    var files = inputElement.get(0).files;
    if (files && files[0]) {
        var fr= new FileReader();
        fr.onload = function(e) {
            deferred.resolve(e.target.result);
        };
        fr.readAsDataURL( files[0] );
    } else {
        deferred.resolve(undefined);
    }

    return deferred.promise();
}

And above function could be used in this way:

var inputElement = $("input[name=file]");
readImage(inputElement).done(function(base64Data){
    alert(base64Data);
});

Or in your case:

$(input).on('change',function(){
  readImage($(this)).done(function(base64Data){ alert(base64Data); });
});

Doing Session.abandon() and destroying the cookie works pretty good. I'm using mvc3 and it looks like the problem occurs if you go to a protected page, log out, and go via your browser history. Not a big deal but still kinda of annoying.

Trying to go through links on my web app works the right way though.

Setting it to not do browser caching may be the way to go.

Or you can just create your own MediaTypeFormatter. I use this for text/html. If you add text/plain to it, it'll work for you too:

public class TextMediaTypeFormatter : MediaTypeFormatter
{
    public TextMediaTypeFormatter()
    {
        SupportedMediaTypes.Add(new MediaTypeHeaderValue("text/html"));
    }

    public override Task<object> ReadFromStreamAsync(Type type, Stream readStream, HttpContent content, IFormatterLogger formatterLogger)
    {
        return ReadFromStreamAsync(type, readStream, content, formatterLogger, CancellationToken.None);
    }

    public override async Task<object> ReadFromStreamAsync(Type type, Stream readStream, HttpContent content, IFormatterLogger formatterLogger, CancellationToken cancellationToken)
    {
        using (var streamReader = new StreamReader(readStream))
        {
            return await streamReader.ReadToEndAsync();
        }
    }

    public override bool CanReadType(Type type)
    {
        return type == typeof(string);
    }

    public override bool CanWriteType(Type type)
    {
        return false;
    }
}

Finally you have to assign this to the HttpMethodContext.ResponseFormatter property.

I just checked the status of the response object:

$promise.then( function successCallback(response) {  
  console.log(response);
  if (response.status === 200) { ... }
});

It is standard matplotlib.pyplot:

...
import matplotlib.pyplot as plt
plt.ylim(10, 40)

Or simpler, as mwaskom comments below:

ax.set(ylim=(10, 40))

Try obuildfactory.

There is need to modify these scripts (contains error and don't exactly do the "thing" required), i will upload mine scripts forked from obuildfactory in next few days. and so i will also update my answer accordingly.

Until then enjoy, sir :)

Just for reference as it was something I was looking for, you can test for presence within the values or the index by appending the ".values" method, e.g.

g in df.<your selected field>.values
g in df.index.values

I find that adding the ".values" to get a simple list or ndarray out makes exist or "in" checks run more smoothly with the other python tools. Just thought I'd toss that out there for people.

If you want some icons (or all) from font-awesome including yout custom svg icons you can:

1- Go to http://fontawesome.io/ Download the zip and extract-it for example in your Desktop.

2- Go to http://fontastic.me/ use your email to create an account.

3- Once you have been logged-in click on the header option: Add More Icons.

4- Select the SVG of font-awesome located in your extracted zip inside fonts.

5- Repeat the procces uploading your own svg files.

6- Inside Home (at the header of the page) Select the icons you want to download, customize them to give your custom names and select publish to have a link or download the fonts and css.

Sorry about my english ! :D

Can we make an Android NFC as the tag which an NFC reader will get data from?

The Nexus S supports peer-to-peer mode, which as its name implies, causes one phone to act as a tag which another phone can read. There was a really good Google I/O session on NFC this year. I would recommended watching it if you're at all interested in NFC.

Change visible="false" to style="visibility:hidden" on your tags..

or better use a class to show/hide the labels..

.hidden{
   visibility:hidden;
}

then on your labels add class="hidden"

and with your script remove the class

document.getElementById("endTimeLabel").className = 'hidden'; // to hide

and

document.getElementById("endTimeLabel").className = ''; // to show

In Android studio we have few ways to auto-generated comments:

• Method I:

By typing /** and Then pressing Enter you can generate next comment line and it will auto-generate the params, etc. but when you need the hotkey for this check out method II on below.

• **Method II: **

1 - Goto topMenu

2 - File > Settings

3 - Select Keymap from settings

4 - On the top right search bar search for "Fix Doc"

5 - Select the "fix doc comment" from the results and double-click on it

6 - Select Add keyboard shortcut from the opened drop down after double-click

7 - Press the shortcut keys on the keyboard

8 - Goto your code and where you want to add some comment press the shortcut key

9 - Enjoy!

WARNING: Security researches have found several poisoned packages on PyPI, including a package named urllib, which will 'phone home' when installed. If you used pip install urllib some time after June 2017, remove that package as soon as possible.

You can't, and you don't need to.

urllib2 is the name of the library included in Python 2. You can use the urllib.request library included with Python 3, instead. The urllib.request library works the same way urllib2 works in Python 2. Because it is already included you don't need to install it.

If you are following a tutorial that tells you to use urllib2 then you'll find you'll run into more issues. Your tutorial was written for Python 2, not Python 3. Find a different tutorial, or install Python 2.7 and continue your tutorial on that version. You'll find urllib2 comes with that version.

Alternatively, install the requests library for a higher-level and easier to use API. It'll work on both Python 2 and 3.

@Baba's answer is great. But you don't need to use explode because fputcsv takes an array as a parameter

For instance, if you have a three columns, four lines document, here's a more straight version:

header('Content-Type: text/csv');
header('Content-Disposition: attachment; filename="sample.csv"');

$user_CSV[0] = array('first_name', 'last_name', 'age');

// very simple to increment with i++ if looping through a database result 
$user_CSV[1] = array('Quentin', 'Del Viento', 34);
$user_CSV[2] = array('Antoine', 'Del Torro', 55);
$user_CSV[3] = array('Arthur', 'Vincente', 15);

$fp = fopen('php://output', 'wb');
foreach ($user_CSV as $line) {
    // though CSV stands for "comma separated value"
    // in many countries (including France) separator is ";"
    fputcsv($fp, $line, ',');
}
fclose($fp);

Java 8 style, using the java.time classes:

// Monday, February 29 is a leap day in 2016 (otherwise, February only has 28 days)
LocalDate start = LocalDate.parse("2016-02-28"),
          end   = LocalDate.parse("2016-03-02");

// 4 days between (end is inclusive in this example)
Stream.iterate(start, date -> date.plusDays(1))
        .limit(ChronoUnit.DAYS.between(start, end) + 1)
        .forEach(System.out::println);

Output:

2016-02-28
2016-02-29
2016-03-01
2016-03-02

Alternative:

LocalDate next = start.minusDays(1);
while ((next = next.plusDays(1)).isBefore(end.plusDays(1))) {
    System.out.println(next);
}

Java 9 added the datesUntil() method:

start.datesUntil(end.plusDays(1)).forEach(System.out::println);

An 8-digit hex color value is a representation of ARGB (Alpha, Red, Green, Blue), whereas a 6-digit value just assumes 100% opacity (fully opaque) and defines just the RGB values. So to make this be fully opaque, you can either use #FF555555, or just #555555. Each 2-digit hex value is one byte, representing values from 0-255.

Here is the official documentation of ArrayList.get().

Anyway it is very simple, for example

ArrayList list = new ArrayList();
list.add("1");
list.add("2");
list.add("3");
String str = (String) list.get(0); // here you get "1" in str

All the answers above are helpful but none solved my issue. In my production file, my STATIC_URL was https://<URL>/static and I used the same STATIC_URL in my dev settings.py file.

This causes a silent failure in django/conf/urls/static.py.

The test elif not settings.DEBUG or '://' in prefix: picks up the '//' in the URL and does not add the static URL pattern, causing no static files to be found.

It would be thoughtful if Django spit out an error message stating you can't use a http(s):// with DEBUG = True

I had to change STATIC_URL to be '/static/'

For example, you can try:

//If you want to get user, you need start query in your mysql:
SELECT user(); // output your user: root@localhost
SELECT system_user(); // --

//If you want to get port your "mysql://user:pass@hostname:port/db"
SELECT @@port; //3306 is default

//If you want hostname your db, you can execute query
SELECT @@hostname;

Have a look at Hashtables, Hashmaps, HashSets and so forth. They all store the hashed key as their keys. When invoking get(Object key) the hash of the parameter is generated and lookup in the given hashes.

When not overwriting hashCode() and the instance of the key has been changed (for example a simple string that doesn't matter at all), the hashCode() could result in 2 different hashcodes for the same object, resulting in not finding your given key in map.get().

I have used:

<a href="javascript://nop/" class="someClass">Text</a>

This works for me.

Create a network with docker network create --subnet=172.17.0.0/16 selnet

Run docker image docker run --net selnet --ip 172.18.0.2 hub

At first, I got

docker: Error response from daemon: Invalid address 172.17.0.2: It does not belong to any of this network's subnets.
ERRO[0000] error waiting for container: context canceled

Solution: Increased the 2nd quadruple of the IP [.18. instead of .17.]

You need to check your settings.xml file under <maven_home>/conf directory.

I would suggest you check out the various tutorials that are coming out lately. My current fav is:

http://nodetuts.com/

Hope this helps.

With JavaScript:

window.parent.location.href= "http://www.google.com";

Modern browsers support vh and vw units, which are a percentage of the window viewport.

So you can have pure CSS borders as a percentage of the window size:

border: 5vw solid red;

Try this example and change window width; the border will change thickness as the window changes size. box-sizing: border-box; may be useful too.

I think this is the most clear solution, using an extension method:

public static class HttpRequestMessageExtensions
{
    private const string HttpContext = "MS_HttpContext";
    private const string RemoteEndpointMessage = "System.ServiceModel.Channels.RemoteEndpointMessageProperty";

    public static string GetClientIpAddress(this HttpRequestMessage request)
    {
        if (request.Properties.ContainsKey(HttpContext))
        {
            dynamic ctx = request.Properties[HttpContext];
            if (ctx != null)
            {
                return ctx.Request.UserHostAddress;
            }
        }

        if (request.Properties.ContainsKey(RemoteEndpointMessage))
        {
            dynamic remoteEndpoint = request.Properties[RemoteEndpointMessage];
            if (remoteEndpoint != null)
            {
                return remoteEndpoint.Address;
            }
        }

        return null;
    }
}

So just use it like:

var ipAddress = request.GetClientIpAddress();

We use this in our projects.

You can also convert it to an array if you prefer. If Array generics are available:

var args = Array.slice(arguments)

Otherwise:

var args = Array.prototype.slice.call(arguments);

from Mozilla MDN:

You should not slice on arguments because it prevents optimizations in JavaScript engines (V8 for example).

I guess you made it final because you want to prevent other classes from extending RainOnTrees. As Effective Java suggests (item 15), there's another way to keep a class close for extension without making it final:

1. Remove the final keyword;

2. Make its constructor private. No class will be able to extend it because it won't be able to call the super constructor;

3. Create a static factory method to instantiate your class.

   // No more final keyword here.
   public class RainOnTrees {
   
       public static RainOnTrees newInstance() {
           return new RainOnTrees();
       }
   
   
       private RainOnTrees() {
           // Private constructor.
       }
   
       public void startRain() {
   
           // some code here
       }
   }
   

By using this strategy, you'll be able to use Mockito and keep your class closed for extension with little boilerplate code.

If you just want, say, a head line and a content line, you can use:

git commit -m "My head line" -m "My content line."

Note that this creates separate paragraphs - not lines. So there will be a blank line between each two -m lines, e.g.:

My head line

My content line.

One can create an empty array, fill it (otherwise map will skip it) and then map indexes to values:

Array(8).fill().map((_, i) => i * i);

As for "Note: we're using maven 2 for our build. I've tried using maven's pre- & post-integration-test phases, but, if a test fails, maven stops and doesn't run post-integration-test, which is no help."

you can try the failsafe-plugin instead, I think it has the facility to ensure cleanup occurs regardless of setup or intermediate stage status

$("#dropdownList option[text='it\'s me']").attr("selected","selected"); 

You could always use something like mktime to create a known time (midnight, last night) and use difftime to get a double-precision time difference between the two. For a platform-independant solution, unless you go digging into the details of your libraries, you're not going to do much better than that. According to the C spec, the definition of time_t is implementation-defined (meaning that each implementation of the library can define it however they like, as long as library functions with use it behave according to the spec.)

That being said, the size of time_t on my linux machine is 8 bytes, which suggests a long int or a double. So I did:

int main()
{
    for(;;)
    {
        printf ("%ld\n", time(NULL));
        printf ("%f\n", time(NULL));
        sleep(1);
    }
    return 0;
}

The time given by the %ld increased by one each step and the float printed 0.000 each time. If you're hell-bent on using printf to display time_ts, your best bet is to try your own such experiment and see how it work out on your platform and with your compiler.

A natural join is just a shortcut to avoid typing, with a presumption that the join is simple and matches fields of the same name.

SELECT
  *
FROM
  table1
NATURAL JOIN
  table2
    -- implicitly uses `room_number` to join

Is the same as...

SELECT
  *
FROM
  table1
INNER JOIN
  table2
    ON table1.room_number = table2.room_number

What you can't do with the shortcut format, however, is more complex joins...

SELECT
  *
FROM
  table1
INNER JOIN
  table2
    ON (table1.room_number = table2.room_number)
    OR (table1.room_number IS NULL AND table2.room_number IS NULL)

Java 8 introduces the Instant.ofEpochSecond utility method for creating an Instant from a Unix timestamp, this can then be converted into a ZonedDateTime and finally formatted, e.g.:

final DateTimeFormatter formatter = 
    DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");

final long unixTime = 1372339860;
final String formattedDtm = Instant.ofEpochSecond(unixTime)
        .atZone(ZoneId.of("GMT-4"))
        .format(formatter);

System.out.println(formattedDtm);   // => '2013-06-27 09:31:00'

I thought this might be useful for people who are using Java 8.

Once sockaddr cast to sockaddr_in, it becomes this:

struct sockaddr_in {
    u_short     sin_family;
    u_short     sin_port;
    struct      in_addr sin_addr;
    char        sin_zero[8];
};

You can also add

Python is a dynamic, strongly typed, object oriented, multipurpose programming language, designed to be quick (to learn, to use, and to understand), and to enforce a clean and uniform syntax.

1. Python is dynamically typed: it means that you don't declare a type (e.g. 'integer') for a variable name, and then assign something of that type (and only that type). Instead, you have variable names, and you bind them to entities whose type stays with the entity itself. a = 5 makes the variable name a to refer to the integer 5. Later, a = "hello" makes the variable name a to refer to a string containing "hello". Static typed languages would have you declare int a and then a = 5, but assigning a = "hello" would have been a compile time error. On one hand, this makes everything more unpredictable (you don't know what a refers to). On the other hand, it makes very easy to achieve some results a static typed languages makes very difficult.
2. Python is strongly typed. It means that if a = "5" (the string whose value is '5') will remain a string, and never coerced to a number if the context requires so. Every type conversion in python must be done explicitly. This is different from, for example, Perl or Javascript, where you have weak typing, and can write things like "hello" + 5 to get "hello5".
3. Python is object oriented, with class-based inheritance. Everything is an object (including classes, functions, modules, etc), in the sense that they can be passed around as arguments, have methods and attributes, and so on.
4. Python is multipurpose: it is not specialised to a specific target of users (like R for statistics, or PHP for web programming). It is extended through modules and libraries, that hook very easily into the C programming language.
5. Python enforces correct indentation of the code by making the indentation part of the syntax. There are no control braces in Python. Blocks of code are identified by the level of indentation. Although a big turn off for many programmers not used to this, it is precious as it gives a very uniform style and results in code that is visually pleasant to read.
6. The code is compiled into byte code and then executed in a virtual machine. This means that precompiled code is portable between platforms.

Python can be used for any programming task, from GUI programming to web programming with everything else in between. It's quite efficient, as much of its activity is done at the C level. Python is just a layer on top of C. There are libraries for everything you can think of: game programming and openGL, GUI interfaces, web frameworks, semantic web, scientific computing...

            start *= 10
            end *= 10

    def __call__(self, number, *args, **kwargs):
        return self.generated_list[number]

                if self.how_much == nbr:
                    break
            nbr += 1

and to run it:

The event attribute of <f:ajax> can hold at least all supported DOM events of the HTML element which is been generated by the JSF component in question. An easy way to find them all out is to check all on* attribues of the JSF input component of interest in the JSF tag library documentation and then remove the "on" prefix. For example, the <h:inputText> component which renders <input type="text"> lists the following on* attributes (of which I've already removed the "on" prefix so that it ultimately becomes the DOM event type name):

• blur
• change
• click
• dblclick
• focus
• keydown
• keypress
• keyup
• mousedown
• mousemove
• mouseout
• mouseover
• mouseup
• select

Additionally, JSF has two more special event names for EditableValueHolder and ActionSource components, the real HTML DOM event being rendered depends on the component type:

• valueChange (will render as change on text/select inputs and as click on radio/checkbox inputs)
• action (will render as click on command links/buttons)

The above two are the default events for the components in question.

Some JSF component libraries have additional customized event names which are generally more specialized kinds of valueChange or action events, such as PrimeFaces <p:ajax> which supports among others tabChange, itemSelect, itemUnselect, dateSelect, page, sort, filter, close, etc depending on the parent <p:xxx> component. You can find them all in the "Ajax Behavior Events" subsection of each component's chapter in PrimeFaces Users Guide.

GREAT article on when not to use a rules Engine...(as well as when to use one)....

http://www.jessrules.com/guidelines.shtml

Another option is if you have a linear set of rules that only apply once in any order to get an outcome is to create a groovy interface and have developers write and deploy these new rules. The advantage is that it is wickedly fast because normally you would pass the hibernate session OR jdbc session as well as any parameters so you have access to all your apps data but in an efficient manner. With a fact list, there can be alot of looping/matching that really can slow the system down.....It's another way to avoid a rules engine and be able to be deployed dynamically(yes, our groovy rules were deployed in a database and we had no recursion....it either met the rule or it didn't). It is just another option.....oh and one more benefit is not learning rules syntax for incoming developers. They have to learn some groovy but that is very close to java so the learning curve is much better.

It really depends on your context. Rules engine have their place and the above is just another option if you have rules on a project that you may want to deploy dynamically for very simplified situations that don't require a rules engine.

BASICALLY do NOT use a rules engine if you have a simple ruleset and can have a groovy interface instead.....just as dynamically deployable and new developers joining your team can learn it faster than the drools language.(but that's my opinion)

Same as the updating existing collection field, $set will add a new fields if the specified field does not exist.

Check out this example:

> db.foo.find()
> db.foo.insert({"test":"a"})
> db.foo.find()
{ "_id" : ObjectId("4e93037bbf6f1dd3a0a9541a"), "test" : "a" }
> item = db.foo.findOne()
{ "_id" : ObjectId("4e93037bbf6f1dd3a0a9541a"), "test" : "a" }
> db.foo.update({"_id" :ObjectId("4e93037bbf6f1dd3a0a9541a") },{$set : {"new_field":1}})
> db.foo.find()
{ "_id" : ObjectId("4e93037bbf6f1dd3a0a9541a"), "new_field" : 1, "test" : "a" }

EDIT:

In case you want to add a new_field to all your collection, you have to use empty selector, and set multi flag to true (last param) to update all the documents

db.your_collection.update(
  {},
  { $set: {"new_field": 1} },
  false,
  true
)

EDIT:

In the above example last 2 fields false, true specifies the upsert and multi flags.

Upsert: If set to true, creates a new document when no document matches the query criteria.

Multi: If set to true, updates multiple documents that meet the query criteria. If set to false, updates one document.

This is for Mongo versions prior to 2.2. For latest versions the query is changed a bit

db.your_collection.update({},
                          {$set : {"new_field":1}},
                          {upsert:false,
                          multi:true}) 

For me I quit Skype, which was occupying port 80, then Apache ran happily on port 80, than I ran Skype and it picked another port this time.

If you want to just remove one dir (or file) you can use Groovy and Manage Jenkins ? Scripts Console run a script which removes it.

For example, you can look at the files with:

dh = new File('./bitnami/jenkins/jenkins_home/workspace/jobname/folder')
dh.eachFile {
  println(it)
}

And then, when you have the folder you want to delete in dh, you could simply append the next code:

dh.deleteDir()

And it will be deleted.

Note: The path shown in the example is for a Bitnami Jenkins installation, yours could be different.

I actually found something that worked for me. It converts the text to binary and then to UTF8.

Source Text that has encoding issues: If ‘Yes’, what was your last

SELECT CONVERT(CAST(CONVERT(
    (SELECT CONVERT(CAST(CONVERT(english_text USING LATIN1) AS BINARY) USING UTF8) AS res FROM m_translation WHERE id = 865) 
USING LATIN1) AS BINARY) USING UTF8) AS 'result';

Corrected Result text: If ‘Yes’, what was your last

My source was wrongly encoded twice so I had two do it twice. For one time you can use:

SELECT CONVERT(CAST(CONVERT(column_name USING latin1) AS BINARY) USING UTF8) AS res FROM m_translation WHERE id = 865;

Please excuse me for any formatting mistakes

In React Router version 5.0.1 and above, you can use:

<Link to="route" target="_blank" onClick={(event) => {event.preventDefault(); window.open(this.makeHref("route"));}} />

Updated Answer for Express 4.x

Rather than using res.send(404) as in old versions of Express, the new method is:

res.sendStatus(404);

Express will send a very basic 404 response with "Not Found" text:

HTTP/1.1 404 Not Found
X-Powered-By: Express
Vary: Origin
Content-Type: text/plain; charset=utf-8
Content-Length: 9
ETag: W/"9-nR6tc+Z4+i9RpwqTOwvwFw"
Date: Fri, 23 Oct 2015 20:08:19 GMT
Connection: keep-alive

Not Found

Just write:

private static double balance = 0;

and you could also write those like that:

private static int id = 0;
private static double annualInterestRate = 0;
public static java.util.Date dateCreated;

DickFeynman's answer is a workable solution for any circumstance in which JQuery is not a good fit, or isn't otherwise necessary. As ComFreek notes, this requires setting the CORS headers on the server-side. If it's your service, and you have a handle on the bigger question of security, then that's entirely feasible.

Here's a listing of a Flask service, setting the CORS headers, grabbing data from a database, responding with JSON, and working happily with DickFeynman's approach on the client-side:

#!/usr/bin/env python 
from __future__ import unicode_literals
from flask      import Flask, Response, jsonify, redirect, request, url_for
from your_model import *
import os
try:
    import simplejson as json;
except ImportError:
    import json
try:
    from flask.ext.cors import *
except:
    from flask_cors import *

app = Flask(__name__)

@app.before_request
def before_request():
try:
    # Provided by an object in your_model
    app.session = SessionManager.connect()
except:
    print "Database connection failed."

@app.teardown_request
def shutdown_session(exception=None):
    app.session.close()

# A route with a CORS header, to enable your javascript client to access 
# JSON created from a database query.
@app.route('/whatever-data/', methods=['GET', 'OPTIONS'])
@cross_origin(headers=['Content-Type'])
def json_data():
    whatever_list = []
    results_json  = None
    try:
        # Use SQL Alchemy to select all Whatevers, WHERE size > 0.
        whatevers = app.session.query(Whatever).filter(Whatever.size > 0).all()
        if whatevers and len(whatevers) > 0:
            for whatever in whatevers:
                # Each whatever is able to return a serialized version of itself. 
                # Refer to your_model.
                whatever_list.append(whatever.serialize())
             # Convert a list to JSON. 
             results_json = json.dumps(whatever_list)
    except SQLAlchemyError as e:
        print 'Error {0}'.format(e)
        exit(0)

    if len(whatevers) < 1 or not results_json:
        exit(0)
    else:
        # Because we used json.dumps(), rather than jsonify(), 
        # we need to create a Flask Response object, here.
        return Response(response=str(results_json), mimetype='application/json')

if __name__ == '__main__':
    #@NOTE Not suitable for production. As configured, 
    #      your Flask service is in debug mode and publicly accessible.  
    app.run(debug=True, host='0.0.0.0', port=5001) # http://localhost:5001/

your_model contains the serialization method for your whatever, as well as the database connection manager (which could stand a little refactoring, but suffices to centralize the creation of database sessions, in bigger systems or Model/View/Control architectures). This happens to use postgreSQL, but could just as easily use any server side data store:

#!/usr/bin/env python 
# Filename: your_model.py

      Base = declarative_base(metadata=whatever_metadata)
      return Base

Base = SessionManager.declareBase()

class Whatever(Base):
    """Create, supply information about, and manage the state of one or more whatever.

        self.whatever_digest         = whatever_digest
        self.best_name               = best_name

        self.whatever_raw            = whatever_raw
        self.whatever_label          = whatever_label

    # Serialize one way or another, just handle appropriately in the client.  
    def serialize(self):
        return {
            'best_name'     :self.best_name,
            'whatever_label':self.whatever_label,
            'size'          :self.size,
        }

In retrospect, I might have serialized the whatever objects as lists, rather than a Python dict, which might have simplified their processing in the Flask service, and I might have separated concerns better in the Flask implementation (The database call probably shouldn't be built-in the the route handler), but you can improve on this, once you have a working solution in your own development environment.

Also, I'm not suggesting people avoid JQuery. But, if JQuery's not in the picture, for one reason or another, this approach seems like a reasonable alternative.

It works, in any case.

Here's my implementation of DickFeynman's approach, in the the client:

<script type="text/javascript">
    var addr = "dev.yourserver.yourorg.tld"
    var port = "5001"

    function Get(whateverUrl){
        var Httpreq = new XMLHttpRequest(); // a new request
        Httpreq.open("GET",whateverUrl,false);
        Httpreq.send(null);
        return Httpreq.responseText;          
    }

    var whatever_list_obj = JSON.parse(Get("http://" + addr + ":" + port + "/whatever-data/"));
    whatever_qty = whatever_list_obj.length;
    for (var i = 0; i < whatever_qty; i++) {
        console.log(whatever_list_obj[i].best_name);
    }
</script>

I'm not going to list my console output, but I'm looking at a long list of whatever.best_name strings.

More to the point: The whatever_list_obj is available for use in my javascript namespace, for whatever I care to do with it, ...which might include generating graphics with D3.js, mapping with OpenLayers or CesiumJS, or calculating some intermediate values which have no particular need to live in my DOM.

Here are some easy to folow steps and a great on hover tutorial its the examples that you can "play" with and test live.

http://fivera.net/simple-cool-live-examples-image-hover-css-effect/

while (<@INC>)

This joins the paths in @INC together in a string, separated by spaces, then calls glob() on the string, which then iterates through the space-separated components (unless there are file-globbing meta-characters.)

This doesn't work so well if there are paths in @INC containing spaces, \, [], {}, *, ?, or ~, and there seems to be no reason to avoid the safe alternative:

for (@INC)

Removing the name from your binding will make it apply to all endpoints, and should produce the desired results. As so:

<services>
  <service name="Service.IService">
    <clear />
    <endpoint binding="basicHttpBinding" contract="Service.IService" />
  </service>
</services>
<bindings>
  <basicHttpBinding>
    <binding maxBufferSize="2147483647" maxReceivedMessageSize="2147483647">
      <readerQuotas maxDepth="32" maxStringContentLength="2147483647"
        maxArrayLength="16348" maxBytesPerRead="4096" maxNameTableCharCount="16384" />
    </binding>
  </basicHttpBinding>
  <webHttpBinding>
    <binding maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" />
  </webHttpBinding>
</bindings>

Also note that I removed the bindingConfiguration attribute from the endpoint node. Otherwise you would get an exception.

This same solution was found here : Problem with large requests in WCF

It's really this simple

var dragged = false
window.addEventListener('mousedown', function () { dragged = false })
window.addEventListener('mousemove', function () { dragged = true })
window.addEventListener('mouseup', function() {
        if (dragged == true) { return }
        console.log("CLICK!! ")
})

You honestly do not want to add a threshold allowing a small movement. The above is the correct, normal, feel of clicking on all desktop interfaces.

Just try it.

You can easily add an event if you like.

There is a lot of options and they all have their pros and cons. Here is list of options ordered by implementation difficulty.

Option 1: Use an API (the easiest)

• ApiFlash (based on chrome)
• EvoPDF (has an option for html)
• Grabzit
• ...

Pros

• Execute Javascript
• Near perfect rendering
• Fast when caching options are correctly used
• Scale is handled by the APIs
• Precise timing, viewport, ...
• Most of the time they offer a free plan

Cons

• Not free if you plan to use them a lot

Option 2: Use one of the many available libraries

• dom-to-image
• wkhtmltoimage (included in the wkhtmltopdf tool)
• phpwkhtmltopdf
• ...

Pros

• Conversion is quite fast most of the time

Cons

• Bad rendering
• Does not execute javascript
• No support for recent web features (FlexBox, Advanced Selectors, Webfonts, Box Sizing, Media Queries, HTML5 tags...)
• Sometimes not so easy to install
• Complicated to scale

Option 3: Use PhantomJs and maybe a wrapper library

• PhantomJs
• php-phantomjs (php wrapper library for PhantomJs)
• ...

Pros

• Execute Javascript
• Quite fast

Cons

• Bad rendering
• PhantomJs has been deprecated and is not maintained anymore.
• No support for recent web features (FlexBox, Advanced Selectors, Webfonts, Box Sizing, Media Queries, HTML5 tags...)
• Complicated to scale
• Not so easy to make it work if there is images to be loaded ...

Option 4: Use Chrome Headless and maybe a wrapper library

• Chrome Headless
• chrome-devtools-protocol
• puphpeteer
• ...

Pros

• Execute Javascript
• Near perfect rendering

Cons

• Not so easy to have exactly the wanted result regarding:
  • page load timing
  • proxy integration
  • auto scrolling
  • ...
• Complicated to scale
• Quite slow and even slower if the html contains external links

Disclaimer: I'm the founder of ApiFlash. I did my best to provide an honest and useful answer.

If i understand you correctly, (i probably don't)

'SELECT @RowCount = COUNT(*)
                   FROM dbo.Comm_Services
                   WHERE CompanyId = ' + CAST(@CompanyId AS CHAR) + '
                   AND ' + @condition

It may come when the API(you are consuming) is not sending the corresponding JSON. You may experience the response as 404 page or something like HTML/XML response.

Easy method is try os.system:

import os
text = 'this is text'
os.system("echo %s | grep 't*'" % text)

string strHeader = Request.Headers["XYZComponent"]
bool bHeader = Boolean.TryParse(strHeader, out bHeader ) && bHeader;

if "true" than true
if "false" or anything else ("fooBar") than false

or

string strHeader = Request.Headers["XYZComponent"]
bool b;
bool? bHeader = Boolean.TryParse(strHeader, out b) ? b : default(bool?);

if "true" than true
if "false" than false
else ("fooBar") than null

DECLARE @BirthDate datetime, @AgeInMonths int
SET @BirthDate = '10/5/1971'
SET @AgeInMonths                              -- Determine the age in "months old":
    = DATEDIFF(MONTH, @BirthDate, GETDATE())  -- .Get the difference in months
    - CASE WHEN DATEPART(DAY,GETDATE())       -- .If today was the 1st to 4th,
              < DATEPART(DAY,@BirthDate)      --   (or before the birth day of month)
           THEN 1 ELSE 0 END                  --   ... don't count the month.
SELECT @AgeInMonths / 12 as AgeYrs            -- Divide by 12 months to get the age in years
      ,@AgeInMonths % 12 as AgeXtraMonths     -- Get the remainder of dividing by 12 months = extra months
      ,DATEDIFF(DAY                           -- For the extra days, find the difference between, 
               ,DATEADD(MONTH, @AgeInMonths   -- 1. Last Monthly Birthday 
                             , @BirthDate)    --     (if birthdays were celebrated monthly)
               ,GETDATE()) as AgeXtraDays     -- 2. Today's date.

In my case mysql and ubuntu 18.04

I set it permanently using this command

sudo nano /etc/mysql/mysql.conf.d/mysqld.cnf

Append the line after the configuration. See example highlighted in the image below.

sql_mode = ""

Note :You can also add different modes here, it depends on your need NO_BACKSLASH_ESCAPES,STRICT_TRANS_TABLE,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

See Available sql modes reference and Documentation

Then save. After saving you need to restart your mysql service, follow the command below:

sudo service mysql restart

Hope this helps :-)

Independent of your original question, you will get better performance if you capture references to local variables rather than index into your list multiple times:

AllIntegerIDs ids = new AllIntegerIDs();
ids.m_MessageID = (int)IntegerIDsSubstring[IntOffset];
ids.m_MessageType = (int)IntegerIDsSubstring[IntOffset + 1];
ids.m_ClassID = (int)IntegerIDsSubstring[IntOffset + 2];
ids.m_CategoryID = (int)IntegerIDsSubstring[IntOffset + 3];
ids.m_MessageText = MessageTextSubstring;
integerList.Add(ids);

And in your for loop:

for (int cnt3 = 0 ; cnt3 < integerList.Count ; cnt3++) //<----PROBLEM HERE
{
   AllIntegerIDs ids = integerList[cnt3];
   Console.WriteLine("{0}\t{1}\t{2}\t{3}\t{4}\n",
      ids.m_MessageID,ids.m_MessageType,ids.m_ClassID,ids.m_CategoryID, ids.m_MessageText);
}

Just an update.

Now if it's a github repository then using just a github shorthand is enough if you do not mind the version of course.

What is the difference between creating cookies on the server and on the client?

What you are referring to are the 2 ways in which cookies can be directed to be set on the client, which are:

• By server
• By client ( browser in most cases )

By server: The Set-cookie response header from the server directs the client to set a cookie on that particular domain. The implementation to actually create and store the cookie lies in the browser. For subsequent requests to the same domain, the browser automatically sets the Cookie request header for each request, thereby letting the server have some state to an otherwise stateless HTTP protocol. The Domain and Path cookie attributes are used by the browser to determine which cookies are to be sent to a server. The server only receives name=value pairs, and nothing more.

By Client: One can create a cookie on the browser using document.cookie = cookiename=cookievalue. However, if the server does not intend to respond to any random cookie a user creates, then such a cookie serves no purpose.

Are these called server side cookies and client side cookies?

Cookies always belong to the client. There is no such thing as server side cookie.

Is there a way to create cookies that can only be read on the server or on the client?

Since reading cookie values are upto the server and client, it depends if either one needs to read the cookie at all. On the client side, by setting the HttpOnly attribute of the cookie, it is possible to prevent scripts ( mostly Javscript ) from reading your cookies , thereby acting as a defence mechanism against Cookie theft through XSS, but sends the cookie to the intended server only.

Therefore, in most of the cases since cookies are used to bring 'state' ( memory of past user events ), creating cookies on client side does not add much value, unless one is aware of the cookies the server uses / responds to.

Just a reminder of a mistake I made myself too, the

 __block

declaration must be done when first declaring the variable, that is, OUTSIDE of the block, not inside of it. This should resolve problems mentioned in the comments about the variable not retaining its value outside of the block.

I don't see any problem, unless you are not managing them using a connection pool.

If you use connection pool, these connections are re-used instead of initiating new connections. so basically, leaving open connections and re-use them it is less problematic than re-creating them each time.

If you want to perform this inside your program then I would do something like:

#include <unistd.h>
int main()
{
  if(chdir("/c") < 0 )  
  {
     printf("Failed\n");
     return -1 ;
  }

  // rest of your program...

}

You can use regular expressions, such as finding a type of string:

case foo
when /^(true|false)$/
   puts "Given string is boolean"
when /^[0-9]+$/ 
   puts "Given string is integer"
when /^[0-9\.]+$/
   puts "Given string is float"
else
   puts "Given string is probably string"
end

Ruby's case will use the equality operand === for this (thanks @JimDeville). Additional information is available at "Ruby Operators". This also can be done using @mmdemirbas example (without parameter), only this approach is cleaner for these types of cases.

You'll have to download the image firstly

public static Bitmap loadBitmap(String url) {
    Bitmap bitmap = null;
    InputStream in = null;
    BufferedOutputStream out = null;

    try {
        in = new BufferedInputStream(new URL(url).openStream(), IO_BUFFER_SIZE);

        final ByteArrayOutputStream dataStream = new ByteArrayOutputStream();
        out = new BufferedOutputStream(dataStream, IO_BUFFER_SIZE);
        copy(in, out);
        out.flush();

        final byte[] data = dataStream.toByteArray();
        BitmapFactory.Options options = new BitmapFactory.Options();
        //options.inSampleSize = 1;

        bitmap = BitmapFactory.decodeByteArray(data, 0, data.length,options);
    } catch (IOException e) {
        Log.e(TAG, "Could not load Bitmap from: " + url);
    } finally {
        closeStream(in);
        closeStream(out);
    }

    return bitmap;
}

Then use the Imageview.setImageBitmap to set bitmap into the ImageView

puts false or true --> prints: false

puts false || true --> prints: true

Use jquery animate and give it a long duration say 2000

$("#Friends").animate({ 
        top: "-=30px",
      }, duration );

The -= means that the animation will be relative to the current top position.

Note that the Friends element must have position set to relative in the css:

#Friends{position:relative;}

Just use the XCOPY command with recursive option

xcopy c:\*.doc k:\mybackup /sy

/s will make it "recursive"

What to change? Aside from the 3 or 4 dimensional array problem, you should get rid of the magic numbers (10 and 9).

const int DIM_SIZE = 10;
int myArray[DIM_SIZE][DIM_SIZE][DIM_SIZE];

for (int i = 0; i < DIM_SIZE; ++i){
    for (int t = 0; t < DIM_SIZE; ++t){            
        for (int x = 0; x < DIM_SIZE; ++x){

mvnrepository.com isn't a repository. It's a search engine. It might or might not tell you what repository it found stuff in if it's not central; since you didn't post an example, I can't help you read the output.

To a file:

require 'csv'
CSV.open("myfile.csv", "w") do |csv|
  csv << ["row", "of", "CSV", "data"]
  csv << ["another", "row"]
  # ...
end

To a string:

require 'csv'
csv_string = CSV.generate do |csv|
  csv << ["row", "of", "CSV", "data"]
  csv << ["another", "row"]
  # ...
end

Here's the current documentation on CSV: http://ruby-doc.org/stdlib/libdoc/csv/rdoc/index.html

OK, first of all I'm not sure how it works when you create a div using (document.createElement('div')), so I might be wrong now, but wouldn't it be possible to use the :target pseudo class selector for this?

If you look at the code below, you can se I've used a link to target the div, but in your case it might be possible to target #new from the script instead and that way make the div fade in without user interaction, or am I thinking wrong?

Here's the code for my example:

HTML

<a href="#new">Click</a> 
<div id="new">
    Fade in ... 
</div>

CSS

#new {
    width: 100px;
    height: 100px;
    border: 1px solid #000000;
    opacity: 0;    
}


#new:target {
    -webkit-transition: opacity 2.0s ease-in;
       -moz-transition: opacity 2.0s ease-in;
         -o-transition: opacity 2.0s ease-in;
                                  opacity: 1;
}

... and here's a jsFiddle

For Linux C applications:

This is my reworked code from an answer above that follows my C code practices and returns a random buffer of any size (with proper return codes, etc.). Make sure to call urandom_open() once at the beginning of your program.

int gUrandomFd = -1;

int urandom_open(void)
{
    if (gUrandomFd == -1) {
        gUrandomFd = open("/dev/urandom", O_RDONLY);
    }

    if (gUrandomFd == -1) {
        fprintf(stderr, "Error opening /dev/urandom: errno [%d], strerrer [%s]\n",
                  errno, strerror(errno));
        return -1;
    } else {
        return 0;
    }
}


void urandom_close(void)
{
    close(gUrandomFd);
    gUrandomFd = -1;
}


//
// This link essentially validates the merits of /dev/urandom:
// http://sockpuppet.org/blog/2014/02/25/safely-generate-random-numbers/
//
int getRandomBuffer(uint8_t *buf, int size)
{
    int ret = 0; // Return value

    if (gUrandomFd == -1) {
        fprintf(stderr, "Urandom (/dev/urandom) file not open\n");
        return -1;
    }

    ret = read(gUrandomFd, buf, size);

    if (ret != size) {
        fprintf(stderr, "Only read [%d] bytes, expected [%d]\n",
                 ret, size);
        return -1;
    } else {
        return 0;
    }
}

Your Mileage May Vary, I attempted @senderle's spin on Vartec's solution in Windows on Python 2.6.5, but I was getting errors, and no other solutions worked. My error was: WindowsError: [Error 6] The handle is invalid.

I found that I had to assign PIPE to every handle to get it to return the output I expected - the following worked for me.

import subprocess

def run_command(cmd):
    """given shell command, returns communication tuple of stdout and stderr"""
    return subprocess.Popen(cmd, 
                            stdout=subprocess.PIPE, 
                            stderr=subprocess.PIPE, 
                            stdin=subprocess.PIPE).communicate()

and call like this, ([0] gets the first element of the tuple, stdout):

run_command('tracert 11.1.0.1')[0]

After learning more, I believe I need these pipe arguments because I'm working on a custom system that uses different handles, so I had to directly control all the std's.

To stop console popups (with Windows), do this:

def run_command(cmd):
    """given shell command, returns communication tuple of stdout and stderr"""
    # instantiate a startupinfo obj:
    startupinfo = subprocess.STARTUPINFO()
    # set the use show window flag, might make conditional on being in Windows:
    startupinfo.dwFlags |= subprocess.STARTF_USESHOWWINDOW
    # pass as the startupinfo keyword argument:
    return subprocess.Popen(cmd,
                            stdout=subprocess.PIPE, 
                            stderr=subprocess.PIPE, 
                            stdin=subprocess.PIPE, 
                            startupinfo=startupinfo).communicate()

run_command('tracert 11.1.0.1')

I created a PHP class for this with a corresponding jQuery plugin. I've open-sourced it at https://github.com/peterjtracey/timezoneWidget - the PHP code is inspired by another stackoverflow answer, but I think much more elegant. The jQuery plugin gives a great interface for selecting a timezone.

This appears to be an (undocumented) "GNU extension": [correction: I finally found a mention in the docs. See below.]

The following command uses the -dM option to print all preprocessor defines; since the input "file" is empty, it shows exactly the predefined macros. It was run with gcc-4.7.3 on a standard ubuntu install. You can see that the preprocessor is standard-aware. In total, there 243 macros with -std=gnu99 and 240 with -std=c99; I filtered the output for relevance.

$ cpp --std=c89 -dM < /dev/null | grep linux
#define __linux 1
#define __linux__ 1
#define __gnu_linux__ 1

$ cpp --std=gnu89 -dM < /dev/null | grep linux
#define __linux 1
#define __linux__ 1
#define __gnu_linux__ 1
#define linux 1

$ cpp --std=c99 -dM < /dev/null | grep linux
#define __linux 1
#define __linux__ 1
#define __gnu_linux__ 1

$ cpp --std=gnu99 -dM < /dev/null | grep linux
#define __linux 1
#define __linux__ 1
#define __gnu_linux__ 1
#define linux 1

The "gnu standard" versions also #define unix. (Using c11 and gnu11 produces the same results.)

I suppose they had their reasons, but it seems to me to make the default installation of gcc (which compiles C code with -std=gnu89 unless otherwise specified) non-conformant, and -- as in this question -- surprising. Polluting the global namespace with macros whose names don't begin with an underscore is not permitted in a conformant implementation. (6.8.10p2: "Any other predefined macro names shall begin with a leading underscore followed by an uppercase letter or a second underscore," but, as mentioned in Appendix J.5 (portability issues), such names are often predefined.)

When I originally wrote this answer, I wasn't able to find any documentation in gcc about this issue, but I did finally discover it, not in C implementation-defined behaviour nor in C extensions but in the cpp manual section 3.7.3, where it notes that:

We are slowly phasing out all predefined macros which are outside the reserved namespace. You should never use them in new programs…

Unfortunately, the answer to your question of whether there is official Material support for selecting the time is "No", but it's currently an open issue on the official Material2 GitHub repo: https://github.com/angular/material2/issues/5648

Hopefully this changes soon, in the mean time, you'll have to fight with the 3rd-party ones you've already discovered. There are a few people in that GitHub issue that provide their self-made workarounds that you can try.

Definitely you can't access form in scope bec. it is not created. The DOM from html template is loaded little bit slowly like controller constructor. the solution is to watch until DOM loaded and all the scope defined!

in controller:

$timeout(function(){
    console.log('customerForm:', $scope.customerForm);
    // everything else what you need
});

max-width works for me.

aside {
  flex: 0 1 200px;
  max-width: 200px;
}

Variables of CSS pre-processors allows to avoid hard-coding.

aside {
  $WIDTH: 200px;
  flex: 0 1 $WIDTH;
  max-width: $WIDTH;
}

overflow: hidden also works, but I lately I try do not use it because it hides the elements as popups and dropdowns.

Update July 2020:

The default for the parameter stringsAsFactors is now default.stringsAsFactors() which in turn yields FALSE as its default.

Assuming your list of lists is called l:

df <- data.frame(matrix(unlist(l), nrow=length(l), byrow=TRUE))

The above will convert all character columns to factors, to avoid this you can add a parameter to the data.frame() call:

df <- data.frame(matrix(unlist(l), nrow=132, byrow=TRUE),stringsAsFactors=FALSE)

Lots of people advise you to use git update-index --assume-unchanged. Indeed, this may be a good solution, but only in the short run.

What you probably want to do is this: git update-index --skip-worktree.

(The third option, which you probably don't want is: git rm --cached. It will keep your local file, but will be marked as removed from the remote repository.)

Difference between the first two options?

• assume-unchanged is to temporary allow you to hide modifications from a file. If you want to hide modifications done to a file, modify the file, then checkout another branch, you'll have to use no-assume-unchanged then probably stash modifications done.
• skip-worktree will follow you whatever the branch you checkout, with your modifications!

Use case of assume-unchanged

It assumes this file should not be modified, and gives you a cleaner output when doing git status. But when checking out to another branch, you need to reset the flag and commit or stash changes before so. If you pull with this option activated, you'll need to solve conflicts and git won't auto merge. It actually only hides modifications (git status won't show you the flagged files).

I like to use it when I only want to stop tracking changes for a while + commit a bunch of files (git commit -a) related to the same modification.

Use case of skip-worktree

You have a setup class containing parameters (eg. including passwords) that your friends have to change accordingly to their setup.

• 1: Create a first version of this class, fill in fields you can fill and leave others empty/null.
• 2: Commit and push it to the remote server.
• 3: git update-index --skip-worktree MySetupClass.java
• 4: Update your configuration class with your own parameters.
• 5: Go back to work on another functionnality.

The modifications you do will follow you whatever the branch. Warning: if your friends also want to modify this class, they have to have the same setup, otherwise their modifications would be pushed to the remote repository. When pulling, the remote version of the file should overwrite yours.

PS: do one or the other, but not both as you'll have undesirable side-effects. If you want to try another flag, you should disable the latter first.

Add hide class to alert-message. Then put the following code after your jQuery script import:

$(document).ready( function(){
    $(".alert-message").animate({ 'height':'toggle','opacity':'toggle'});
    window.setTimeout( function(){
        $(".alert-message").slideUp();
    }, 2500);
});

If you want handle multiple messages, this code will hide them in ascending order:

$(document).ready( function(){
   var hide_delay = 2500;  // starting timeout before first message is hidden
   var hide_next = 800;   // time in mS to wait before hiding next message
   $(".alert-message").slideDown().each( function(index,el) {
      window.setTimeout( function(){
         $(el).slideUp();  // hide the message
      }, hide_delay + hide_next*index);
   });
});

I have done that the more simple way, not as clean as it should be but it was a quick hack

$htmlContent = file_get_contents('pageURL');

// read all image tags into an array
preg_match_all('/<img[^>]+>/i',$htmlContent, $imgTags); 

for ($i = 0; $i < count($imgTags[0]); $i++) {
  // get the source string
  preg_match('/src="([^"]+)/i',$imgTags[0][$i], $imgage);

  // remove opening 'src=' tag, can`t get the regex right
  $origImageSrc[] = str_ireplace( 'src="', '',  $imgage[0]);
}
// will output all your img src's within the html string
print_r($origImageSrc);

CSS 3 can solve this problem. Unfortunately it's only supported on 60% of used browsers nowadays.

For Internet Explorer and iOS you can't turn off resizing, but you can limit the textarea dimension by setting its width and height.

/* One can also turn on/off specific axis. Defaults to both on. */
textarea { resize:vertical; } /* none|horizontal|vertical|both */

See Demo

You can also try pressing the "FN" or function key with the button "Break" or with the button "sys rq" - system request as this - must be pressed together and this stops any running macro

JSON.stringify takes more optional arguments.

Try:

 JSON.stringify({a:1,b:2,c:{d:1,e:[1,2]}}, null, 4); // Indented 4 spaces
 JSON.stringify({a:1,b:2,c:{d:1,e:[1,2]}}, null, "\t"); // Indented with tab

How can I beautify JSON programmatically?

Should work in modern browsers, and it is included in json2.js if you need a fallback for browsers that don't support the JSON helper functions. For display purposes, put the output in a <pre> tag to get newlines to show.

I use the following in a batch file:

path = %path%;C:\Windows\Microsoft.NET\Framework\v2.0.50727
regasm httpHelper\bin\Debug\httpHelper.dll /tlb:.\httpHelper.tlb /codebase

Most of the answers are in jquery. You can do this perfectly in pure Javascript, simple and no library required. This article was a good starting point for me but since keyIdentifier is deprecated, I wanted this code to be more secure so I added ||e.keyCode==8 to the if statement. Also, the code wasn't working well on Firefox so I added return false; and now it works perfectly well. Here it is:

<script type="text/javascript">
window.addEventListener('keydown',function(e){if(e.keyIdentifier=='U+0008'||e.keyIdentifier=='Backspace'||e.keyCode==8){if(e.target==document.body){e.preventDefault();return false;}}},true);
</script>

This code works great because,

1. It is in pure javascript (no library required).
2. Not only it checks the key pressed, it confirms if the action is really a browser "back" action.
3. Together with the above, user can type and delete text from input text boxes on the web page without any problems while still preventing the back button action.
4. It is short, clean, fast and straight to the point.

You can add console.log(e); for your your test purposes, and hit F12 in chrome, go to "console" tab and hit "backspace" on the page and look inside it to see what values are returned, then you can target all of those parameters to further enhance the code above to suit your needs.

Here is a solution using history Read more

import { createBrowserHistory } from "history";

const history = createBrowserHistory()

inside Router

<Router>
   {history.location.pathname}
</Router>

its a simple

{!! $text !!}

laravel compile as a dom element and {{$text}} print as a string

It is simple in javascript using array reduce method:

const arr = ['a','d','r','a','a','f','d'];
const result =  arr.reduce((json,val)=>({...json, [val]:(json[val] | 0) + 1}),{});
console.log(result)
//{ a:3,d:2,r:1,f:1 }

update-java-alternatives

The java executable is not found with your JAVA_HOME, it only depends on your PATH.

update-java-alternatives is a good way to manage it for the entire system is through:

update-java-alternatives -l

Sample output:

java-7-oracle 1 /usr/lib/jvm/java-7-oracle
java-8-oracle 2 /usr/lib/jvm/java-8-oracle

Choose one of the alternatives:

sudo update-java-alternatives -s java-7-oracle

Like update-alternatives, it works through symlink management. The advantage is that is manages symlinks to all the Java utilities at once: javac, java, javap, etc.

I am yet to see a JAVA_HOME effect on the JDK. So far, I have only seen it used in third-party tools, e.g. Maven.

Using Query parameter

<a href="edit.jsp?userId=${user.id}" />  

Using Hidden variable .

<form method="post" action="update.jsp">  
...  
   <input type="hidden" name="userId" value="${user.id}">  

you can send Using Session object.

   session.setAttribute("userId", userid);

These values will now be available from any jsp as long as your session is still active.

   int userid = session.getAttribute("userId"); 

This should do it, let me know if you have trouble with it:

Sub foo()
Dim x As Workbook
Dim y As Workbook

'## Open both workbooks first:
Set x = Workbooks.Open(" path to copying book ")
Set y = Workbooks.Open(" path to destination book ")

'Now, copy what you want from x:
x.Sheets("name of copying sheet").Range("A1").Copy

'Now, paste to y worksheet:
y.Sheets("sheetname").Range("A1").PasteSpecial

'Close x:
x.Close

End Sub

Alternatively, you could just:

Sub foo2()
Dim x As Workbook
Dim y As Workbook

'## Open both workbooks first:
Set x = Workbooks.Open(" path to copying book ")
Set y = Workbooks.Open(" path to destination book ")

'Now, transfer values from x to y:
y.Sheets("sheetname").Range("A1").Value = x.Sheets("name of copying sheet").Range("A1") 

'Close x:
x.Close

End Sub

To extend this to the entire sheet:

With x.Sheets("name of copying sheet").UsedRange
    'Now, paste to y worksheet:
    y.Sheets("sheet name").Range("A1").Resize( _
        .Rows.Count, .Columns.Count) = .Value
End With

And yet another way, store the value as a variable and write the variable to the destination:

Sub foo3()
Dim x As Workbook
Dim y As Workbook
Dim vals as Variant

'## Open both workbooks first:
Set x = Workbooks.Open(" path to copying book ")
Set y = Workbooks.Open(" path to destination book ")

'Store the value in a variable:
vals = x.Sheets("name of sheet").Range("A1").Value

'Use the variable to assign a value to the other file/sheet:
y.Sheets("sheetname").Range("A1").Value = vals 

'Close x:
x.Close

End Sub

The last method above is usually the fastest for most applications, but do note that for very large datasets (100k rows) it's observed that the Clipboard actually outperforms the array dump:

Copy/PasteSpecial vs Range.Value = Range.Value

That said, there are other considerations than just speed, and it may be the case that the performance hit on a large dataset is worth the tradeoff, to avoid interacting with the Clipboard.

You must try this in keydown event

here is the code for that :

private void textBox1_KeyDown(object sender, KeyEventArgs e)
    {
        if (e.Key == Key.Enter)
        {
            MessageBox.Show("Enter pressed");
        }
    }

Update :

Also you can do this with keypress event.

Try This :

private void textBox1_KeyPress(object sender, KeyPressEventArgs e)
    {
        if (e.KeyChar == Convert.ToChar(Keys.Return))
        {
            MessageBox.Show("Key pressed");
        }
    }

Some great answers above, using that info here is what I did today to solve the same issue:

$to_array = explode(',', $to);
foreach($to_array as $address)
{
    $mail->addAddress($address, 'Web Enquiry');
}

It may be useful to know about CodeTimestamps, which provide a wrapper around mach-based timing functions. This gives you nanosecond-resolution timing data - 1000000x more precise than milliseconds. Yes, a million times more precise. (The prefixes are milli, micro, nano, each 1000x more precise than the last.) Even if you don't need CodeTimestamps, check out the code (it's open source) to see how they use mach to get the timing data. This would be useful when you need more precision and want a faster method call than the NSDate approach.

Best answer I found

To get the remote ip address the quickest way possible. You must have to use a downloader, or create a server on your computer.

The downsides to using this simple code: (which is recommended) is that it will take 3-5 seconds to get your Remote IP Address because the WebClient when initialized always takes 3-5 seconds to check for your proxy settings.

 public static string GetIP()
 {
            string externalIP = "";
            externalIP = new WebClient().DownloadString("http://checkip.dyndns.org/");
            externalIP = (new Regex(@"\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}"))
                                           .Matches(externalIP)[0].ToString();
            return externalIP;
 }

Here is how I fixed it.. (first time still takes 3-5 seconds) but after that it will always get your Remote IP Address in 0-2 seconds depending on your connection.

public static WebClient webclient = new WebClient();
public static string GetIP()
{
    string externalIP = "";
    externalIP = webclient.DownloadString("http://checkip.dyndns.org/");
    externalIP = (new Regex(@"\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}"))
                                   .Matches(externalIP)[0].ToString();
    return externalIP;
}

If you want folding an all your editors, I found you can enable Folding in

Enable Folding

A quick search on google code gives (it uses formula from @Mark Byers's answer):

def choose(n, k):
    """
    A fast way to calculate binomial coefficients by Andrew Dalke (contrib).
    """
    if 0 <= k <= n:
        ntok = 1
        ktok = 1
        for t in xrange(1, min(k, n - k) + 1):
            ntok *= n
            ktok *= t
            n -= 1
        return ntok // ktok
    else:
        return 0

choose() is 10 times faster (tested on all 0 <= (n,k) < 1e3 pairs) than scipy.misc.comb() if you need an exact answer.

def comb(N,k): # from scipy.comb(), but MODIFIED!
    if (k > N) or (N < 0) or (k < 0):
        return 0L
    N,k = map(long,(N,k))
    top = N
    val = 1L
    while (top > (N-k)):
        val *= top
        top -= 1
    n = 1L
    while (n < k+1L):
        val /= n
        n += 1
    return val

Use the replace function in js:

var emailAdd = $(this).text().replace(/ /g,'');

That will remove all the spaces

If you want to remove the leading and trailing whitespace only, use the jQuery $.trim method :

var emailAdd = $.trim($(this).text());

You could try the following:

select customer1.Id,customer1.Name,customer1.city,CustAdd.phone,CustAdd.Country
from customer1
inner join [EBST08].[Test].[dbo].[customerAddress] CustAdd
on customer1.Id=CustAdd.CustId

You can use python garbage collector:

import gc
gc.collect()

You need a json serializer to parse your content, probably you already have it, for your initial question on how to make a request, this might be an idea:

var baseAddress = "http://www.example.com/1.0/service/action";

var http = (HttpWebRequest)WebRequest.Create(new Uri(baseAddress));
http.Accept = "application/json";
http.ContentType = "application/json";
http.Method = "POST";

string parsedContent = <<PUT HERE YOUR JSON PARSED CONTENT>>;
ASCIIEncoding encoding = new ASCIIEncoding();
Byte[] bytes = encoding.GetBytes(parsedContent);

Stream newStream = http.GetRequestStream();
newStream.Write(bytes, 0, bytes.Length);
newStream.Close();

var response = http.GetResponse();

var stream = response.GetResponseStream();
var sr = new StreamReader(stream);
var content = sr.ReadToEnd();

hope it helps,

To kill from the application, you can do:

android.os.Process.killProcess(android.os.Process.myPid());

I usually start out with some combination of:

typeof(obj)
class(obj)
sapply(obj, class)
sapply(obj, attributes)
attributes(obj)
names(obj)

as appropriate based on what's revealed. For example, try with:

obj <- data.frame(a=1:26, b=letters)
obj <- list(a=1:26, b=letters, c=list(d=1:26, e=letters))
data(cars)
obj <- lm(dist ~ speed, data=cars)

..etc.

If obj is an S3 or S4 object, you can also try methods or showMethods, showClass, etc. Patrick Burns' R Inferno has a pretty good section on this (sec #7).

EDIT: Dirk and Hadley mention str(obj) in their answers. It really is much better than any of the above for a quick and even detailed peek into an object.

I am using this for formatting numbers without trailing zeroes in our JSF application. The original built-in formatters required you to specify max numbers of fractional digits which could be useful here also in case you have too many fractional digits.

/**
 * Formats the given Number as with as many fractional digits as precision
 * available.<br>
 * This is a convenient method in case all fractional digits shall be
 * rendered and no custom format / pattern needs to be provided.<br>
 * <br>
 * This serves as a workaround for {@link NumberFormat#getNumberInstance()}
 * which by default only renders up to three fractional digits.
 *
 * @param number
 * @param locale
 * @param groupingUsed <code>true</code> if grouping shall be used
 *
 * @return
 */
public static String formatNumberFraction(final Number number, final Locale locale, final boolean groupingUsed)
{
    if (number == null)
        return null;

    final BigDecimal bDNumber = MathUtils.getBigDecimal(number);

    final NumberFormat numberFormat = NumberFormat.getNumberInstance(locale);
    numberFormat.setMaximumFractionDigits(Math.max(0, bDNumber.scale()));
    numberFormat.setGroupingUsed(groupingUsed);

    // Convert back for locale percent formatter
    return numberFormat.format(bDNumber);
}

/**
 * Formats the given Number as percent with as many fractional digits as
 * precision available.<br>
 * This is a convenient method in case all fractional digits shall be
 * rendered and no custom format / pattern needs to be provided.<br>
 * <br>
 * This serves as a workaround for {@link NumberFormat#getPercentInstance()}
 * which does not renders fractional digits.
 *
 * @param number Number in range of [0-1]
 * @param locale
 *
 * @return
 */
public static String formatPercentFraction(final Number number, final Locale locale)
{
    if (number == null)
        return null;

    final BigDecimal bDNumber = MathUtils.getBigDecimal(number).multiply(new BigDecimal(100));

    final NumberFormat percentScaleFormat = NumberFormat.getPercentInstance(locale);
    percentScaleFormat.setMaximumFractionDigits(Math.max(0, bDNumber.scale() - 2));

    final BigDecimal bDNumberPercent = bDNumber.multiply(new BigDecimal(0.01));

    // Convert back for locale percent formatter
    final String strPercent = percentScaleFormat.format(bDNumberPercent);

    return strPercent;
}

is there a possibility that casting a double created via Math.round() will still result in a truncated down number

No, round() will always round your double to the correct value, and then, it will be cast to an long which will truncate any decimal places. But after rounding, there will not be any fractional parts remaining.

Here are the docs from Math.round(double):

Returns the closest long to the argument. The result is rounded to an integer by adding 1/2, taking the floor of the result, and casting the result to type long. In other words, the result is equal to the value of the expression:

(long)Math.floor(a + 0.5d)

If you're using Maven, set the <encoding> explicitly in the compiler plugin's configuration, e.g.

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>2.3.2</version>
            <configuration>
                <encoding>UTF-8</encoding>
            </configuration>
        </plugin>

I know this is a very old question. Just posting this here as I solved this problem using FlexBox. Here is the solution

#container {
  height: 100%;
  width: 100%;
  display: flex;
}
#leftThing {
  width: 25%;
  background-color: blue;
}
#content {
  width: 50%;
  background-color: green;
}
#rightThing {
  width: 25%;
  background-color: yellow;
}

<div id="container">

  <div id="leftThing">
    Left Side Menu
  </div>

  <div id="content">
    Random Content
  </div>

  <div id="rightThing">
    Right Side Menu
  </div>

</div>

Just had to add display:flex to the container! No floats required.

Since strptime returns a datetime object which has tzinfo attribute, We can simply replace it with desired timezone.

>>> import datetime

>>> date_time_str = '2018-06-29 08:15:27.243860'
>>> date_time_obj = datetime.datetime.strptime(date_time_str, '%Y-%m-%d %H:%M:%S.%f').replace(tzinfo=datetime.timezone.utc)
>>> date_time_obj.tzname()
'UTC'

You should not try to use perfmon, task manager or any tool like that to determine memory leaks. They are good for identifying trends, but not much else. The numbers they report in absolute terms are too vague and aggregated to be useful for a specific task such as memory leak detection.

A previous reply to this question has given a great explanation of what the various types are.

You ask about a tool recommendation: I recommend Memory Validator. Capable of monitoring applications that make billions of memory allocations.

To write/save

%%writefile myfile.py

• write/save cell contents into myfile.py (use -a to append). Another alias: %%file myfile.py

To run

%run myfile.py

• run myfile.py and output results in the current cell

To load/import

%load myfile.py

• load "import" myfile.py into the current cell

For more magic and help

%lsmagic

• list all the other cool cell magic commands.

%COMMAND-NAME?

• for help on how to use a certain command. i.e. %run?

Note

Beside the cell magic commands, IPython notebook (now Jupyter notebook) is so cool that it allows you to use any unix command right from the cell (this is also equivalent to using the %%bash cell magic command).

To run a unix command from the cell, just precede your command with ! mark. for example:

• !python --version see your python version
• !python myfile.py run myfile.py and output results in the current cell, just like %run (see the difference between !python and %run in the comments below).

Also, see this nbviewer for further explanation with examples. Hope this helps.

Yup, and sun.misc.BASE64Decoder is way slower: 9x slower than java.xml.bind.DatatypeConverter.parseBase64Binary() and 4x slower than org.apache.commons.codec.binary.Base64.decodeBase64(), at least for a small string on Java 6 OSX.

Below is the test program I used. With Java 1.6.0_43 on OSX:

john:password = am9objpwYXNzd29yZA==
javax.xml took 373: john:password
apache took    612: john:password
sun took       2215: john:password

Btw that's with commons-codec 1.4. With 1.7 it seems to get slower:

javax.xml took 377: john:password
apache took    1681: john:password
sun took       2197: john:password

Didn't test Java 7 or other OS.

import javax.xml.bind.DatatypeConverter;
import org.apache.commons.codec.binary.Base64;
import java.io.IOException;

public class TestBase64 {
    private static volatile String save = null;

        String teststr = "john:password";
        String b64 = DatatypeConverter.printBase64Binary(teststr.getBytes());

        try {
            final int COUNT = 1000000;

            for (int i=0; i<COUNT; ++i) {
                save = new String(DatatypeConverter.parseBase64Binary(b64));
            }

A generic tree is a node with zero or more children, each one a proper (tree) node. It isn't the same as a binary tree, they're different data structures, although both shares some terminology.

There isn't any builtin data structure for generic trees in Python, but it's easily implemented with classes.

class Tree(object):
    "Generic tree node."
    def __init__(self, name='root', children=None):
        self.name = name
        self.children = []
        if children is not None:
            for child in children:
                self.add_child(child)
    def __repr__(self):
        return self.name
    def add_child(self, node):
        assert isinstance(node, Tree)
        self.children.append(node)
#    *
#   /|\
#  1 2 +
#     / \
#    3   4
t = Tree('*', [Tree('1'),
               Tree('2'),
               Tree('+', [Tree('3'),
                          Tree('4')])])

<?php

    $start_date = '2015-01-01';
    $end_date = '2015-06-30';

    while (strtotime($start_date) <= strtotime($end_date)) {
        echo "$start_daten";
        $start_date = date ("Y-m-d", strtotime("+1 days", strtotime($start_date)));
    }

?>

I too liked Jordan's answer and implemented it myself. I only needed to abbreviations so in case someone else needs the same:

You need to put the worksheet identifier in your range statements as shown below ...

 Option Explicit
 Dim ws As Worksheet, a As Range

Sub forEachWs()

For Each ws In ActiveWorkbook.Worksheets
Call resizingColumns
Next

End Sub

Sub resizingColumns()
ws.Range("A:A").ColumnWidth = 20.14
ws.Range("B:B").ColumnWidth = 9.71
ws.Range("C:C").ColumnWidth = 35.86
ws.Range("D:D").ColumnWidth = 30.57
ws.Range("E:E").ColumnWidth = 23.57
ws.Range("F:F").ColumnWidth = 21.43
ws.Range("G:G").ColumnWidth = 18.43
ws.Range("H:H").ColumnWidth = 23.86
ws.Range("i:I").ColumnWidth = 27.43
ws.Range("J:J").ColumnWidth = 36.71
ws.Range("K:K").ColumnWidth = 30.29
ws.Range("L:L").ColumnWidth = 31.14
ws.Range("M:M").ColumnWidth = 31
ws.Range("N:N").ColumnWidth = 41.14
ws.Range("O:O").ColumnWidth = 33.86
End Sub

The easiest way now is to add it as a module

This will create a new module containing the aar file, so you just need to include that module as a dependency afterwards

I've created a tool to SSH and CD into a server consecutively – aptly named sshcd. For the example you've given, you'd simply use:

sshcd somehost:/some/directory/somewhere/named/Foo

Here is another variation on the Bootstrap 4.1 Navbar with multi-level dropdown. This one uses minimal CSS for the submenu, and can be re-positioned as desired:

https://www.codeply.com/go/nG6iMAmI2X

.dropdown-submenu {
  position: relative;
}

.dropdown-submenu .dropdown-menu {
  top: 0;
  left: 100%;
  margin-top: -1px;
}

jQuery to control display of submenus:

$('.dropdown-submenu > a').on("click", function(e) {
    var submenu = $(this);
    $('.dropdown-submenu .dropdown-menu').removeClass('show');
    submenu.next('.dropdown-menu').addClass('show');
    e.stopPropagation();
});

$('.dropdown').on("hidden.bs.dropdown", function() {
    // hide any open menus when parent closes
    $('.dropdown-menu.show').removeClass('show');
});

See this answer for activating the Bootstrap 4 submenus on hover

You need convert list to numpy array and then reshape:

df = pd.DataFrame(np.array(my_list).reshape(3,3), columns = list("abc"))
print (df)
   a  b  c
0  1  2  3
1  4  5  6
2  7  8  9

The answers here are all quite old.

In the HTML5 world, you should the use onpopstate event.

window.onpopstate = function(event)
{
    alert("location: " + document.location + ", state: " + JSON.stringify(event.state));
};

Or:

window.addEventListener('popstate', function(event)
{
    alert("location: " + document.location + ", state: " + JSON.stringify(event.state));
});

The latter snippet allows multiple event handlers to exist, whereas the former will replace any existing handler which may cause hard-to-find bugs.

In my case, Dropbox overlays were starting with a " (quoted identifier) in the registry. I deleted all the " prefixes and restarted explorer.exe.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\explorer\ShellIconOverlayIdentifiers

Edit: I installed Windows 10 and this solution didn't work for me. So I just went to the same registry location and deleted all Google and SkyDrive records and restarted explorer.exe.

Second edit: After installing TortoiseGit it fixed everything without any customisation.

It was probably discussed, but as of CSS3 there is nothing like what you need (see also "Is there a CSS selector for elements containing certain text?"). You will have to use additional markup, like this:

<li><span class="foo">some text</span></li>
<li>some other text</li>

Then refer to it the usual way:

li > span.foo {...}

Although this is an old question, there is a very easy way to do this in Java 11 which was released today: you can use a new overload of Character.toString():

public static String toString?(int codePoint)

Returns a String object representing the specified character (Unicode code point). The result is a string of length 1 or 2, consisting solely of the specified codePoint.

Parameters:
codePoint - the codePoint to be converted

Returns:
the string representation of the specified codePoint

Throws:
IllegalArgumentException - if the specified codePoint is not a valid Unicode code point.

Since:
11

Since this method supports any Unicode code point, the length of the returned String is not necessarily 1.

The code needed for the example given in the question is simply:

    int codePoint = '\u2202';
    String s = Character.toString(codePoint); // <<< Requires JDK 11 !!!
    System.out.println(s); // Prints ?

This approach offers several advantages:

• It works for any Unicode code point rather than just those that can be handled using a char.
• It's concise, and it's easy to understand what the code is doing.
• It returns the value as a string rather than a char[], which is often what you want. The answer posted by McDowell is appropriate if you want the code point returned as char[].

An example to make things concrete. If you have a selection thus:

<select onchange="" onblur="">
  <option>....
</select>

the onblur() is called when you navigate away. The onchange() is called when you select a different option from the selection - i.e. you change what it's currently selected as.

You can also add underscore.js to your project and will be able to do it in one line:

_.map($("input[name='category_ids[]']:checked"), function(el){return $(el).val()})

Another alternative for this (older) question:

import datetime
import pytz
import time

pacific=pytz.timezone('US/Pacific')
now=datetime.datetime.now()
# pacific.dst(now).total_seconds() yields 3600 secs. [aka 1 hour]
time.strftime("%-H", time.gmtime(pacific.dst(now).total_seconds()))
'1'

The above is a good way to tell if your current time zone is actually in daylight savings time or not. (It provides an offset of 0 or 1.) Anyway, the real work is being done by time.strftime("%H:%M:%S", time.gmtime(36901)) which does work on the output of gmtime().

>>> time.strftime("%H:%M:%S",time.gmtime(36901))  # secs = 36901
'10:15:01'

And, that's it! (NOTE: Here's a link to format specifiers for time.strftime(). ...)

not really... I used

 <system.webServer>
     <httpProtocol allowKeepAlive="true" >
       <customHeaders>
         <add name="X-Frame-Options" value="*" />
       </customHeaders>
     </httpProtocol>
 </system.webServer>

You can make a generic class like this:

public class MyProp<T>
{
    private T _value;

    public T Value
    {
        get
        {
            // insert desired logic here
            return _value;
        }
        set
        {
            // insert desired logic here
            _value = value;
        }
    }

    public static implicit operator T(MyProp<T> value)
    {
        return value.Value;
    }

    public static implicit operator MyProp<T>(T value)
    {
        return new MyProp<T> { Value = value };
    }
}

...then use it in a class like so:

class SomeClass
{
    public MyProp<int> SomeProperty { get; set; }
}

The implicit operators means that you do not need to explicitly set or get the Value property of MyProp, but can write code to access the value in a more "natural" way:

SomeClass instance = new SomeClass();
instance.SomeProperty = 32;
int someInt = instance.SomeProperty;

Try this: import headers as mentioned.. gives seconds and milliseconds only. If you need to explain the code read this link.

#include <windows.h>

#include <stdio.h>

void main()
{

    SYSTEMTIME st;
    SYSTEMTIME lt;

    GetSystemTime(&st);
   // GetLocalTime(&lt);

     printf("The system time is: %02d:%03d\n", st.wSecond, st.wMilliseconds);
   //  printf("The local time is: %02d:%03d\n", lt.wSecond, lt.wMilliseconds);

}
