Instead of modding the auto-generated code or wrapping every call in duplicate code, you can inject your custom HTTP headers by adding a custom message inspector, it's easier than it sounds:

public class CustomMessageInspector : IClientMessageInspector
{
    readonly string _authToken;

    public CustomMessageInspector(string authToken)
    {
        _authToken = authToken;
    }

    public object BeforeSendRequest(ref Message request, IClientChannel channel)
    {
        var reqMsgProperty = new HttpRequestMessageProperty();
        reqMsgProperty.Headers.Add("Auth-Token", _authToken);
        request.Properties[HttpRequestMessageProperty.Name] = reqMsgProperty;
        return null;
    }

    public void AfterReceiveReply(ref Message reply, object correlationState)
    { }
}


public class CustomAuthenticationBehaviour : IEndpointBehavior
{
    readonly string _authToken;

    public CustomAuthenticationBehaviour (string authToken)
    {
        _authToken = authToken;
    }
    public void Validate(ServiceEndpoint endpoint)
    { }

    public void AddBindingParameters(ServiceEndpoint endpoint, BindingParameterCollection bindingParameters)
    { }

    public void ApplyDispatchBehavior(ServiceEndpoint endpoint, EndpointDispatcher endpointDispatcher)
    { }

    public void ApplyClientBehavior(ServiceEndpoint endpoint, ClientRuntime clientRuntime)
    {
        clientRuntime.ClientMessageInspectors.Add(new CustomMessageInspector(_authToken));
    }
}

And when instantiating your client class you can simply add it as a behavior:

this.Endpoint.EndpointBehaviors.Add(new CustomAuthenticationBehaviour("Auth Token"));

This will make every outgoing service call to have your custom HTTP header.

Are you mixing C and C++? One issue that can occur is that the declarations in the .h file for a .c file need to be surrounded by:

#if defined(__cplusplus)
  extern "C" {                 // Make sure we have C-declarations in C++ programs
#endif

and:

#if defined(__cplusplus)
  }
#endif

Note: if unable / unwilling to modify the .h file(s) in question, you can surround their inclusion with extern "C":

extern "C" {
#include <abc.h>
} //extern

Another option like Gavin Palmer answer is to use the .pem file but with a curl option

1. download the last updated .pem file from https://curl.haxx.se/docs/caextract.html and save it somewhere on your server(outside the public folder)

2. set the option in your code instead of the php.ini file.

In your code

curl_setopt($ch, CURLOPT_CAINFO, $_SERVER['DOCUMENT_ROOT'] .  "/../cacert-2017-09-20.pem");

NOTE: setting the cainfo in the php.ini like @Gavin Palmer did is better than setting it in your code like I did, because it will save a disk IO every time the function is called, I just make it like this in case you want to test the cainfo file on the fly instead of changing the php.ini while testing your function.

Create a Custom View Engine and have a method that returns a ViewEngineResult In this example you just overwrite the _options.ViewLocationFormats and add your folder directory :

public ViewEngineResult FindView(ActionContext context, string viewName, bool isMainPage)
        {
            var controllerName = context.GetNormalizedRouteValue(CONTROLLER_KEY);
            var areaName = context.GetNormalizedRouteValue(AREA_KEY);

            var checkedLocations = new List<string>();
            foreach (var location in _options.ViewLocationFormats)
            {
                var view = string.Format(location, viewName, controllerName);
                if (File.Exists(view))
                {
                    return ViewEngineResult.Found("Default", new View(view, _ViewRendering));
                }
                checkedLocations.Add(view);
            }

            return ViewEngineResult.NotFound(viewName, checkedLocations);
        }

Example: https://github.com/AspNetMonsters/pugzor

Here's a one line solution:

array_shift((explode('.', $_SERVER['HTTP_HOST'])));

Or using your example:

array_shift((explode('.', 'en.example.com')));

EDIT: Fixed "only variables should be passed by reference" by adding double parenthesis.

EDIT 2: Starting from PHP 5.4 you can simply do:

explode('.', 'en.example.com')[0];

The best way is to use simple math

>>> a = 8
>>> a**(1./3.)
2.0

EDIT

For Negative numbers

>>> a = -8
>>> -(-a)**(1./3.)
-2.0

Complete Program for all the requirements as specified

x = int(input("Enter an integer: "))
if x>0:
    ans = x**(1./3.)
    if ans ** 3 != abs(x):
        print x, 'is not a perfect cube!'
else:
    ans = -((-x)**(1./3.))
    if ans ** 3 != -abs(x):
        print x, 'is not a perfect cube!'

print 'Cube root of ' + str(x) + ' is ' + str(ans)

Interesting little problem. It is a bit tricky, since real numbers, not always represent exact integers, even if they are meant to, so it's important to allow a tolerance.

For instance tolerance could be 1E-6, in the unit tests, I kept a rather coarse tolerance to have shorter numbers.

None of the answers that I can read now works in this way, so here is my solution:

public boolean isInteger(double n, double tolerance) {
    double absN = Math.abs(n);
    return Math.abs(absN - Math.round(absN)) <= tolerance;
}

And the unit test, to make sure it works:

@Test
public void checkIsInteger() {
    final double TOLERANCE = 1E-2;
    assertThat(solver.isInteger(1, TOLERANCE), is(true));

    assertThat(solver.isInteger(0.999, TOLERANCE), is(true));
    assertThat(solver.isInteger(0.9, TOLERANCE), is(false));

    assertThat(solver.isInteger(1.001, TOLERANCE), is(true));
    assertThat(solver.isInteger(1.1, TOLERANCE), is(false));

    assertThat(solver.isInteger(-1, TOLERANCE), is(true));

    assertThat(solver.isInteger(-0.999, TOLERANCE), is(true));
    assertThat(solver.isInteger(-0.9, TOLERANCE), is(false));

    assertThat(solver.isInteger(-1.001, TOLERANCE), is(true));        
    assertThat(solver.isInteger(-1.1, TOLERANCE), is(false));
}

How i resolved this was following the 4th point in this url: https://dev.mysql.com/doc/refman/8.0/en/changing-mysql-user.html

1. Edit my.cnf
2. Add user = root under under [mysqld] group of the file

If this doesn't work then make sure you have changed the password from default.

This may not be exactly what you're looking for (it's not an "easy" solution to send your Tabs to the bottom of the screen) but is nevertheless an interesting alternative solution I would like to flag to you :

ScrollableTabHost is designed to behave like TabHost, but with an additional scrollview to fit more items ...

Swift 4.x Solution

@IBOutlet var yourTextField: UITextField!

 override func viewDidLoad() {
     ....
     yourTextField.addTarget(self, action: #selector(actionTextFieldIsEditingChanged), for: UIControlEvents.editingChanged)
  }

 @objc func actionTextFieldIsEditingChanged(sender: UITextField) {
     if sender.text.isEmpty {
       // textfield is empty
     } else {
       // text field is not empty
     }
  }

Here are my solutions. Their advantages are : easy-understanding code, works for all characters. Enjoy.

Solution 1 :

public static void main(String[] args) {

    String str = "CC%";
    String result = "";
    char[] messChar = str.toCharArray();

    for (int i = 0; i < messChar.length; i++) {
        result += Integer.toBinaryString(messChar[i]) + " ";
    }

    System.out.println(result);
}

prints :

1000011 1000011 100101

Solution 2 :

Possibility to choose the number of displayed bits per char.

public static String toBinary(String str, int bits) {
    String result = "";
    String tmpStr;
    int tmpInt;
    char[] messChar = str.toCharArray();

    for (int i = 0; i < messChar.length; i++) {
        tmpStr = Integer.toBinaryString(messChar[i]);
        tmpInt = tmpStr.length();
        if(tmpInt != bits) {
            tmpInt = bits - tmpInt;
            if (tmpInt == bits) {
                result += tmpStr;
            } else if (tmpInt > 0) {
                for (int j = 0; j < tmpInt; j++) {
                    result += "0";
                }
                result += tmpStr;
            } else {
                System.err.println("argument 'bits' is too small");
            }
        } else {
            result += tmpStr;
        }
        result += " "; // separator
    }

    return result;
}

public static void main(String args[]) {
    System.out.println(toBinary("CC%", 8));
}

prints :

01000011 01000011 00100101

You can enable annotation processors in IntelliJ via the following:

5. Click OK

I was trying to make a borderless windows form movable which contained a WPF Element Host control and a WPF User control.

I ended up with a stack panel called StackPanel in my WPF user control which seemed the logical thing to try click on to move. Trying junmats's code worked when I moved the mouse slowly, but if I moved the mouse faster, the mouse would move off the form and the form would be stuck somewhere mid move.

This improved on his answer for my situation using CaptureMouse and ReleaseCaptureMouse and now the mouse does not move off the form while moving it even if I move it quickly.

private void StackPanel_MouseDown(object sender, MouseButtonEventArgs e)
{
    _start_point = e.GetPosition(this);
    StackPanel.CaptureMouse();
}

private void StackPanel_MouseUp(object sender, MouseButtonEventArgs e)
{
    StackPanel.ReleaseMouseCapture();
}

private void StackPanel_MouseMove(object sender, MouseEventArgs e)
{
    if (StackPanel.IsMouseCaptured)
    {
        var p = _form.GetMousePositionWindowsForms();
        _form.Location = new System.Drawing.Point((int)(p.X - this._start_point.X), (int)(p.Y - this._start_point.Y));
    }
}

    //Global variables;
    private Point _start_point = new Point(0, 0);

You can delete the browser cache by setting these headers:

<?php
header("Expires: Tue, 01 Jan 2000 00:00:00 GMT");
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
header("Cache-Control: no-store, no-cache, must-revalidate, max-age=0");
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache");
?>

you can use send instead of sendFile so you wont face with error! this works will help you!

fs.readFile('public/index1.html',(err,data)=>{
if(err){
  consol.log(err);
}else {
res.setHeader('Content-Type', 'application/pdf');

for telling browser that your response is type of PDF

res.setHeader('Content-Disposition', 'attachment; filename='your_file_name_for_client.pdf');

if you want that file open immediately on the same page after user download it.write 'inline' instead attachment in above code.

res.send(data)

One workaround is just to use select without any other clauses.

A method can't throw two exceptions at the same time. It will always throw the last thrown exception, which in this case it will be always the one from the finally block.

When the first exception from method q() is thrown, it will catch'ed and then swallowed by the finally block thrown exception.

q() -> thrown new Exception -> main catch Exception -> throw new Exception -> finally throw a new exception (and the one from the catch is "lost")

check for this by calling the library jquery after the noconflict.js or that this calling more than once jquery library after the noconflict.js

//This is JavaScript Code.

function countWordOccurences()
{
    // You can use array of words or a sentence split with space.
    var sentence = "The quick brown fox jumped over the lazy dog.";
    //var sentenceArray = ['asdf', 'asdf', 'sfd', 'qwr', 'qwr'];
    var sentenceArray = sentence.split(' ', 1000); 
    var output;
    var temp;
    for(var i = 0; i < sentenceArray.length; i++) {
        var k = 1;
        for(var j = i + 1; j < sentenceArray.length; j++) {
            if(sentenceArray[i] == sentenceArray[j])
                    k = k + 1;
        }
        if(k > 1) {
            i = i + 1;
            output = output + ',' + k + ',' + k;
        }
        else
            output = output + ',' + k;
    }
    alert(sentenceArray + '\n' + output.slice(10).split(',', 500));

If you want to set something on a timer, you can use JavaScript's setTimeout or setInterval methods:

setTimeout ( expression, timeout );
setInterval ( expression, interval );

Where expression is a function and timeout and interval are integers in milliseconds. setTimeout runs the timer once and runs the expression once whereas setInterval will run the expression every time the interval passes.

So in your case it would work something like this:

setInterval(function() {
    //call $.ajax here
}, 5000); //5 seconds

As far as the Ajax goes, see jQuery's ajax() method. If you run an interval, there is nothing stopping you from calling the same ajax() from other places in your code.

If what you want is for an interval to run every 30 seconds until a user initiates a form submission...and then create a new interval after that, that is also possible:

setInterval() returns an integer which is the ID of the interval.

var id = setInterval(function() {
    //call $.ajax here
}, 30000); // 30 seconds

If you store that ID in a variable, you can then call clearInterval(id) which will stop the progression.

Then you can reinstantiate the setInterval() call after you've completed your ajax form submission.

I am using Eclipse mars, Hibernate 5.2.1, Jdk7 and Oracle 11g.

I get the same error when I run Hibernate code generation tool. I guess it is a versions issue due to I have solved it through choosing Hibernate version (5.1 to 5.0) in the type frame in my Hibernate console configuration.

You passed an argument to a function which didn't take any. For example:

def takes_no_arguments
end

takes_no_arguments 1

You can just use numpy arrays. Look at the numpy for matlab users page for a detailed overview of the pros and cons of arrays w.r.t. matrices.

As I mentioned in the comment, having to use the dot() function or method for mutiplication of vectors is the biggest pitfall. But then again, numpy arrays are consistent. All operations are element-wise. So adding or subtracting arrays and multiplication with a scalar all work as expected of vectors.

Edit2: Starting with Python 3.5 and numpy 1.10 you can use the @ infix-operator for matrix multiplication, thanks to pep 465.

Edit: Regarding your comment:

1. Yes. The whole of numpy is based on arrays.

2. Yes. linalg.norm(v) is a good way to get the length of a vector. But what you get depends on the possible second argument to norm! Read the docs.

3. To normalize a vector, just divide it by the length you calculated in (2). Division of arrays by a scalar is also element-wise.

   An example in ipython:

   In [1]: import math
   
   In [2]: import numpy as np
   
   In [3]: a = np.array([4,2,7])
   
   In [4]: np.linalg.norm(a)
   Out[4]: 8.3066238629180749
   
   In [5]: math.sqrt(sum([n**2 for n in a]))
   Out[5]: 8.306623862918075
   
   In [6]: b = a/np.linalg.norm(a)
   
   In [7]: np.linalg.norm(b)
   Out[7]: 1.0
   

   Note that In [5] is an alternative way to calculate the length. In [6] shows normalizing the vector.

the first,Using get_encoding_type to get the files type of encode:

import os    
from chardet import detect

# get file encoding type
def get_encoding_type(file):
    with open(file, 'rb') as f:
        rawdata = f.read()
    return detect(rawdata)['encoding']

the second, opening the files with the type:

open(current_file, 'r', encoding = get_encoding_type, errors='ignore')

${project.basedir} is the root directory of your project.

${project.build.directory} is equivalent to ${project.basedir}/target

as it is defined here: https://github.com/apache/maven/blob/trunk/maven-model-builder/src/main/resources/org/apache/maven/model/pom-4.0.0.xml#L53

Use $key => $val to get the keys:

<?php

$arr = array(
    1 => "Value1",
    2 => "Value2",
    10 => "Value10",
);

foreach ($arr as $key => $val) {
   print "$key\n";
}

?>

I find it more convenient to make a connection using a procedural programming language (like Python) and do these types of queries.

import psycopg2

                                  , port="5432"
                                  , database="myDB"
                                  , host="[ENDPOINT]")
cursor_psql = connection_psql.cursor()

myList = [...]
for item in myList:
  cursor_psql.execute('''
    -- The query goes here
  ''')

connection_psql.commit()
cursor_psql.close()

for some reasons, I couldn't use any of these solutions. so I just declared my route in web.php as $router->get('/api/v1/users', ['as' => 'index', 'uses' => 'UserController@index']) and in my controller I got the name of the route using $routeName = $request->route()[1]['as']; which $request is \Illuminate\Http\Request $request typehinted parameter in index method of UserController

The Boa is good for your needs, see the example which extends Python tensorflow keras.Sequential class in JavaScript.

const fs = require('fs');
const boa = require('@pipcook/boa');
const { tuple, enumerate } = boa.builtins();

const tf = boa.import('tensorflow');
const tfds = boa.import('tensorflow_datasets');

const { keras } = tf;
const { layers } = keras;

const [
  [ train_data, test_data ],
  info
] = tfds.load('imdb_reviews/subwords8k', boa.kwargs({
  split: tuple([ tfds.Split.TRAIN, tfds.Split.TEST ]),
  with_info: true,
  as_supervised: true
}));

const encoder = info.features['text'].encoder;
const padded_shapes = tuple([
  [ null ], tuple([])
]);
const train_batches = train_data.shuffle(1000)
  .padded_batch(10, boa.kwargs({ padded_shapes }));
const test_batches = test_data.shuffle(1000)
  .padded_batch(10, boa.kwargs({ padded_shapes }));

const embedding_dim = 16;
const model = keras.Sequential([
  layers.Embedding(encoder.vocab_size, embedding_dim),
  layers.GlobalAveragePooling1D(),
  layers.Dense(16, boa.kwargs({ activation: 'relu' })),
  layers.Dense(1, boa.kwargs({ activation: 'sigmoid' }))
]);

model.summary();
model.compile(boa.kwargs({
  optimizer: 'adam',
  loss: 'binary_crossentropy',
  metrics: [ 'accuracy' ]
}));

The complete example is at: https://github.com/alibaba/pipcook/blob/master/example/boa/tf2/word-embedding.js

I used Boa in another project Pipcook, which is to address the machine learning problems for JavaScript developers, we implemented ML/DL models upon the Python ecosystem(tensorflow,keras,pytorch) by the boa library.

Just get rid of the parenthesis and that will give you an array with one element and:

• Change this line

var test = tesst.match(/a(.*)j/);

• To this

var test = tesst.match(/a.*j/);

If you add parenthesis the match() function will find two match for you one for whole expression and one for the expression inside the parenthesis

• Also according to developer.mozilla.org docs :

If you only want the first match found, you might want to use RegExp.exec() instead.

You can use the below code:

RegExp(/a.*j/).exec("afskfsd33j")

First drop constraints

https://stackoverflow.com/a/49393045/2547164

DECLARE @ConstraintName nvarchar(200)
SELECT @ConstraintName = Name FROM SYS.DEFAULT_CONSTRAINTS
WHERE PARENT_OBJECT_ID = OBJECT_ID('__TableName__')
AND PARENT_COLUMN_ID = (SELECT column_id FROM sys.columns
                        WHERE NAME = N'__ColumnName__'
                        AND object_id = OBJECT_ID(N'__TableName__'))
IF @ConstraintName IS NOT NULL
EXEC('ALTER TABLE __TableName__ DROP CONSTRAINT ' + @ConstraintName)

Second create default value

ALTER TABLE [table name] ADD DEFAULT [default value] FOR [column name]

Use a timer with an interval set to 2–3 seconds.

You have three different options to choose from, depending on which type of application you're writing:

1. System.Timers.Timer
2. System.Windows.Forms.Timer
3. System.Threading.Timer

Don't use Thread.Sleep if your application need to process any inputs on that thread at the same time (WinForms, WPF), as Sleep will completely lock up the thread and prevent it from processing other messages. Assuming a single-threaded application (as most are), your entire application will stop responding, rather than just delaying an operation as you probably intended. Note that it may be fine to use Sleep in pure console application as there are no "events" to handle or on separate thread (also Task.Delay is better option).

In addition to timers and Sleep you can use Task.Delay which is asynchronous version of Sleep that does not block thread from processing events (if used properly - don't turn it into infinite sleep with .Wait()).

 public async void ClickHandler(...)
 {
      // whatever you need to do before delay goes here         

      await Task.Delay(2000);

      // whatever you need to do after delay.
 }

The same await Task.Delay(2000) can be used in a Main method of a console application if you use C# 7.1 (Async main on MSDN blogs).

Note: delaying operation with Sleep has benefit of avoiding race conditions that comes from potentially starting multiple operations with timers/Delay. Unfortunately freezing UI-based application is not acceptable so you need to think about what will happen if you start multiple delays (i.e. if it is triggered by a button click) - consider disabling such button, or canceling the timer/task or making sure delayed operation can be done multiple times safely.

It's like copy semantics, but instead of having to duplicate all of the data you get to steal the data from the object being "moved" from.

In your case, I would use YAML .

That is an elegant and professional standard for dealing with multiple parameters. The values are loaded from a separate file. You can see some info in this link:

https://keleshev.com/yaml-quick-introduction

But it is easier to Google it, as it is a standard, there are hundreds of info about it, you can find what best fits to your understanding. ;)

Best regards.

Your Test2 class is not a Component, it has a Component which is a difference.

Either you do something like

frame.add(test.getPanel() );

after you introduced a getter for the panel in your class, or you make sure your Test2 class becomes a Component (e.g. by extending a JPanel)

Problem Cause : The process of the current program is still running without interuption. (This is the reason why you haven't got this issue after a restart)

The fix is simple : Go to cmd and type the command taskkill -im process-name.exe -f

Eg:

 taskkill -im demo.exe -f

here,

demo - is my program name

This works just as well: http://jsfiddle.net/maniator/ge59E/3/

Every canvas item is an object that Tkinter keeps track of. If you are clearing the screen by just drawing a black rectangle, then you effectively have created a memory leak -- eventually your program will crash due to the millions of items that have been drawn.

To clear a canvas, use the delete method. Give it the special parameter "all" to delete all items on the canvas (the string "all"" is a special tag that represents all items on the canvas):

canvas.delete("all")

If you want to delete only certain items on the canvas (such as foreground objects, while leaving the background objects on the display) you can assign tags to each item. Then, instead of "all", you could supply the name of a tag.

If you're creating a game, you probably don't need to delete and recreate items. For example, if you have an object that is moving across the screen, you can use the move or coords method to move the item.

I tried with "mMap.animateCamera( CameraUpdateFactory.zoomTo( 17.0f ) );" but it didn't work for me. So I used this animation for zooming in on start.

mMap.addMarker(new MarkerOptions().position(loc).title("Sydney"));
mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(loc, 18), 5000, null);

Concision counts: I prefer window.location = "?single"; or window.location += "?single";

To loop over the key/values, use a for in loop:

for (let key in myDictionary) {
    let value = myDictionary[key];
    // Use `key` and `value`
}

For SQL Developer

You have to execute it manually

SET SERVEROUTPUT ON 

After that if you execute any procedure with DBMS_OUTPUT.PUT_LINE('info'); or directly .

This will print the line

And please don't try to add this

 SET SERVEROUTPUT ON

inside the definition of function and procedure, it will not compile and will not work.

An option is to use the OkHttp client, from Square.

Add the library dependency

In the build.gradle, include this line:

compile 'com.squareup.okhttp:okhttp:x.x.x'

Where x.x.x is the desired library version.

Set the client

For example, if you want to set a timeout of 60 seconds, do this way:

final OkHttpClient okHttpClient = new OkHttpClient();
okHttpClient.setReadTimeout(60, TimeUnit.SECONDS);
okHttpClient.setConnectTimeout(60, TimeUnit.SECONDS);

ps: If your minSdkVersion is greater than 8, you can use TimeUnit.MINUTES. So, you can simply use:

okHttpClient.setReadTimeout(1, TimeUnit.MINUTES);
okHttpClient.setConnectTimeout(1, TimeUnit.MINUTES);

For more details about the units, see TimeUnit.

Is this what you want:

Assembly.GetExecutingAssembly ().Location

DOMDocument is a great choice. It's a module specifically designed for creating and manipulating XML documents. You can create a document from scratch, or open existing documents (or strings) and navigate and modify their structures.

$xml = new DOMDocument();
$xml_album = $xml->createElement("Album");
$xml_track = $xml->createElement("Track");
$xml_album->appendChild( $xml_track );
$xml->appendChild( $xml_album );

$xml->save("/tmp/test.xml");

To re-open and write:

$xml = new DOMDocument();
$xml->load('/tmp/test.xml');
$nodes = $xml->getElementsByTagName('Album') ;
if ($nodes->length > 0) {
   //insert some stuff using appendChild()
}

//re-save
$xml->save("/tmp/test.xml");

It's a conceptual problem.

Stringstream is a stream, so its iterators are forward, cannot return. In an output stringstream, you need a flush() to reinitialize it, as in any other output stream.

It looks like the Django REST framework uses the HTTP accept header in a Request in order to automatically determine which renderer to use:

http://www.django-rest-framework.org/api-guide/renderers/

Using the HTTP accept header may provide an alternative source for your "if something".

I work in Ruby and using Nokogiri I fetch the element and look to see if the result is nil.

require 'nokogiri'

url = "http://somthing.com/resource"

resp = Nokogiri::XML(open(url))

first_name = resp.xpath("/movies/actors/actor[1]/first-name")

puts "first-name not found" if first_name.nil?

Instead of killing the window manager, try running the new one with --replace or -replace if available.

If Primary Key and type needed, this query may be useful:

SELECT L.TABLE_SCHEMA, L.TABLE_NAME, L.COLUMN_NAME, R.TypeName
FROM(
    SELECT COLUMN_NAME, TABLE_NAME, TABLE_SCHEMA
    FROM INFORMATION_SCHEMA.KEY_COLUMN_USAGE
    WHERE OBJECTPROPERTY(OBJECT_ID(CONSTRAINT_SCHEMA + '.' + QUOTENAME(CONSTRAINT_NAME)), 'IsPrimaryKey') = 1
)L
LEFT JOIN (
    SELECT
    OBJECT_NAME(c.OBJECT_ID) TableName ,c.name AS ColumnName ,t.name AS TypeName
    FROM sys.columns AS c
    JOIN sys.types AS t ON c.user_type_id=t.user_type_id
)R ON L.COLUMN_NAME = R.ColumnName AND L.TABLE_NAME = R.TableName

For storing a single row output into a variable from the select into query :

declare v_username varchare(20); SELECT username into v_username FROM users WHERE user_id = '7';

this will store the value of a single record into the variable v_username.

For storing multiple rows output into a variable from the select into query :

you have to use listagg function. listagg concatenate the resultant rows of a coloumn into a single coloumn and also to differentiate them you can use a special symbol. use the query as below SELECT listagg(username || ',' ) within group (order by username) into v_username FROM users;

In Node.js (TypeScript):

import { TextDecoder } from 'util';

function decode(jwt: string) {
    const { 0: encodedHeader, 1: encodedPayload, 2: signature, length } = jwt.split('.');

    if (length !== 3) {
        throw new TypeError('Invalid JWT');
    }

    const decode = (input: string): JSON => { return JSON.parse(new TextDecoder().decode(new Uint8Array(Buffer.from(input, 'base64')))); };

    return { header: decode(encodedHeader), payload: decode(encodedPayload), signature: signature };
}

With jose by panva on GitHub, you could use the minimal import { decode as base64Decode } from 'jose/util/base64url' and replace new Uint8Array(Buffer.from(input, 'base64')) with base64Decode(input). Code should then work in both browser and Node.js.

What solved it for me is to set listeners like so:

advertised.listeners = PLAINTEXT://my.public.ip:9092
listeners = PLAINTEXT://0.0.0.0:9092

This makes KAFKA broker listen to all interfaces.

Good cocoa function:

-(BOOL) NSStringIsValidEmail:(NSString *)checkString
{
   BOOL stricterFilter = NO; // Discussion http://blog.logichigh.com/2010/09/02/validating-an-e-mail-address/
   NSString *stricterFilterString = @"^[A-Z0-9a-z\\._%+-]+@([A-Za-z0-9-]+\\.)+[A-Za-z]{2,4}$";
   NSString *laxString = @"^.+@([A-Za-z0-9-]+\\.)+[A-Za-z]{2}[A-Za-z]*$";
   NSString *emailRegex = stricterFilter ? stricterFilterString : laxString;
   NSPredicate *emailTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", emailRegex];
   return [emailTest evaluateWithObject:checkString];
}

Discussion on Lax vs. Strict - http://blog.logichigh.com/2010/09/02/validating-an-e-mail-address/

And because categories are just better, you could also add an interface:

@interface NSString (emailValidation) 
  - (BOOL)isValidEmail;
@end

Implement

@implementation NSString (emailValidation)
-(BOOL)isValidEmail
{
  BOOL stricterFilter = NO; // Discussion http://blog.logichigh.com/2010/09/02/validating-an-e-mail-address/
  NSString *stricterFilterString = @"^[A-Z0-9a-z\\._%+-]+@([A-Za-z0-9-]+\\.)+[A-Za-z]{2,4}$";
  NSString *laxString = @"^.+@([A-Za-z0-9-]+\\.)+[A-Za-z]{2}[A-Za-z]*$";
  NSString *emailRegex = stricterFilter ? stricterFilterString : laxString;
  NSPredicate *emailTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", emailRegex];
  return [emailTest evaluateWithObject:self];
}
@end

And then utilize:

if([@"[email protected]" isValidEmail]) { /* True */ }
if([@"InvalidEmail@notreallyemailbecausenosuffix" isValidEmail]) { /* False */ }

Here is my answer, I did it for myself and I hope it's simple enough for those who don't want to use the String approach or need a more math-y solution:

public static void reverseNumber2(int number) {

    int residual=0;
    residual=number%10;
    System.out.println(residual);

    while (residual!=number)  {
          number=(number-residual)/10;
          residual=number%10;
          System.out.println(residual);
    }
}

So I just get the units, print them out, substract them from the number, then divide that number by 10 - which is always without any floating stuff, since units are gone, repeat.

Bonus answer: The keyboard shortcut in Visual Studio for commenting out anything is Ctrl-KC . This works in a number of places, including C#, VB, Javascript, and aspx pages; it also works for SQL in SQL Management Studio.

You can either select the text to be commented out, or you can position your text inside a chunk to be commented out; for example, put your cursor inside the opening tag of a GridView, press Ctrl-KC, and the whole thing is commented out.

You can safely delete the WSDL cache files. If you wish to prevent future caching, use:

ini_set("soap.wsdl_cache_enabled", 0);

or dynamically:

$client = new SoapClient('http://somewhere.com/?wsdl', array('cache_wsdl' => WSDL_CACHE_NONE) );

Modern browsers support a for...of loop. The fastest and shortest way to solve this problem in Chrome, Safari, Edge, and Firefox is also the clearest:

let largest = '';
for (let item of arr) {
  if (item.length > largest.length) largest = item
}

In IE, you can use Array.forEach; that's still faster and clearer than sorting or reducing the array.

var largest = '';
arr.forEach(function(item) {
  if (item.length > largest.length) largest = item
});

There is no canonical answer, since XML fundamentally has no null concept. But I assume you want Xml/Object mapping (since object graphs have nulls); so the answer for you is "whatever your tool uses". If you write handling, that means whatever you prefer. For tools that use XML Schema, xsi:nil is the way to go. For most mappers, omitting matching element/attribute is the way to do it.

Other answers here to not take into consideration if you have all-zero's (or even a single zero).
Some always default an empty string to zero, which is wrong when it is supposed to remain blank.
Re-read the original question. This answers what the Questioner wants.

Solution #1:

--This example uses both Leading and Trailing zero's.
--Avoid losing those Trailing zero's and converting embedded spaces into more zeros.
--I added a non-whitespace character ("_") to retain trailing zero's after calling Replace().
--Simply remove the RTrim() function call if you want to preserve trailing spaces.
--If you treat zero's and empty-strings as the same thing for your application,
--  then you may skip the Case-Statement entirely and just use CN.CleanNumber .
DECLARE @WackadooNumber VarChar(50) = ' 0 0123ABC D0 '--'000'--
SELECT WN.WackadooNumber, CN.CleanNumber,
       (CASE WHEN WN.WackadooNumber LIKE '%0%' AND CN.CleanNumber = '' THEN '0' ELSE CN.CleanNumber END)[AllowZero]
 FROM (SELECT @WackadooNumber[WackadooNumber]) AS WN
 OUTER APPLY (SELECT RTRIM(RIGHT(WN.WackadooNumber, LEN(LTRIM(REPLACE(WN.WackadooNumber + '_', '0', ' '))) - 1))[CleanNumber]) AS CN
--Result: "123ABC D0"

Solution #2 (with sample data):

SELECT O.Type, O.Value, Parsed.Value[WrongValue],
       (CASE WHEN CHARINDEX('0', T.Value)  > 0--If there's at least one zero.
              AND LEN(Parsed.Value) = 0--And the trimmed length is zero.
             THEN '0' ELSE Parsed.Value END)[FinalValue],
       (CASE WHEN CHARINDEX('0', T.Value)  > 0--If there's at least one zero.
              AND LEN(Parsed.TrimmedValue) = 0--And the trimmed length is zero.
             THEN '0' ELSE LTRIM(RTRIM(Parsed.TrimmedValue)) END)[FinalTrimmedValue]
  FROM 
  (
    VALUES ('Null', NULL), ('EmptyString', ''),
           ('Zero', '0'), ('Zero', '0000'), ('Zero', '000.000'),
           ('Spaces', '    0   A B C '), ('Number', '000123'),
           ('AlphaNum', '000ABC123'), ('NoZero', 'NoZerosHere')
  ) AS O(Type, Value)--O is for Original.
  CROSS APPLY
  ( --This Step is Optional.  Use if you also want to remove leading spaces.
    SELECT LTRIM(RTRIM(O.Value))[Value]
  ) AS T--T is for Trimmed.
  CROSS APPLY
  ( --From @CadeRoux's Post.
    SELECT SUBSTRING(O.Value, PATINDEX('%[^0]%', O.Value + '.'), LEN(O.Value))[Value],
           SUBSTRING(T.Value, PATINDEX('%[^0]%', T.Value + '.'), LEN(T.Value))[TrimmedValue]
  ) AS Parsed

Results:

Summary:

You could use what I have above for a one-off removal of leading-zero's.
If you plan on reusing it a lot, then place it in an Inline-Table-Valued-Function (ITVF).
Your concerns about performance problems with UDF's is understandable.
However, this problem only applies to All-Scalar-Functions and Multi-Statement-Table-Functions.
Using ITVF's is perfectly fine.

I have the same problem with our 3rd-Party database.
With Alpha-Numeric fields many are entered in without the leading spaces, dang humans!
This makes joins impossible without cleaning up the missing leading-zeros.

Conclusion:

Instead of removing the leading-zeros, you may want to consider just padding your trimmed-values with leading-zeros when you do your joins.
Better yet, clean up your data in the table by adding leading zeros, then rebuilding your indexes.
I think this would be WAY faster and less complex.

SELECT RIGHT('0000000000' + LTRIM(RTRIM(NULLIF(' 0A10  ', ''))), 10)--0000000A10
SELECT RIGHT('0000000000' + LTRIM(RTRIM(NULLIF('', ''))), 10)--NULL --When Blank.

Cursor contacts = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
String aNameFromContacts[] = new String[contacts.getCount()];  
String aNumberFromContacts[] = new String[contacts.getCount()];  
int i = 0;

int nameFieldColumnIndex = contacts.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME);
int numberFieldColumnIndex = contacts.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);

while(contacts.moveToNext()) {

    String contactName = contacts.getString(nameFieldColumnIndex);
    aNameFromContacts[i] =    contactName ; 

    String number = contacts.getString(numberFieldColumnIndex);
    aNumberFromContacts[i] =    number ;
i++;
}

contacts.close();

The result will be aNameFromContacts array full of contacts. Also ensure that you have added

<uses-permission android:name="android.permission.READ_CONTACTS" />

in main.xml

It's because you've removed the id which is how you're finding the element. This line of code is trying to add id="page_navigation1" to an element with the id named page_navigation1, but it doesn't exist (because you deleted the attribute):

$("#page_navigation1").attr("id","page_navigation1");

Demo:

If you want to add and remove a class that makes your <div> red use:

$( '#page_navigation1' ).addClass( 'red-class' );

And:

$( '#page_navigation1' ).removeClass( 'red-class' );

Where red-class is:

.red-class {
    background-color: red;
}

I hit this error because I was specifying a label attribute in my geom (geom_text) but was specifying a color in the top level aes:

df <- read.table('match-stats.tsv', sep='\t')
library(ggplot2)

# don't do this!
ggplot(df, aes(x=V6, y=V1, color=V1)) +
  geom_text(angle=45, label=df$V1, size=2)

To fix this, I just moved the label attribute out of the geom and into the top level aes:

df <- read.table('match-stats.tsv', sep='\t')
library(ggplot2)

# do this!
ggplot(df, aes(x=V6, y=V1, color=V1, label=V1)) +
  geom_text(angle=45, size=2)

Recently I learned of the following syntax:

DELETE (SELECT *
        FROM productfilters pf
        INNER JOIN product pr
            ON pf.productid = pr.id
        WHERE pf.id >= 200
            AND pr.NAME = 'MARK')

I think it looks much cleaner then other proposed code.

Are you sure you have a UIView (or subclass) assigned to the "view" property of yourViewController?

Right click on "File Owner" in the left pane of the xib for yourViewController and verify that the "view" outlet is set. If not, set it to a view!

this will definetly fix the Issue

I had the same issue. What I did is to run mongodb command in another terminal. Then, run my application in another tab. This resolved my problem. Though, I am trying other solution such as creating a script to run mongodb before connection is made.

Structure in C

First you need to declare your structure:

struct mystruct{
 char element_1,
 char element_2
};

Instantiate C structure

Once you declared your structure , you can instantiate a variable that has as type your structure using either:

mystruct struct_example;

or :

mystruct* struct_example;

For the first use case you can access the varaiable eleemnet using the following syntax: struct_example.element_1 = 5;

For the second use case which is having a pointer to variable of type your structure, to be able to access the variable structure you need an arrow:

struct_example->element_1 = 5;

{% for days in days_list %}
    <h2># Day {{ forloop.counter }} - From {{ days.from_location }} to {{ days.to_location }}</h2>
{% endfor %}

or if you want to start from 0

{% for days in days_list %}
        <h2># Day {{ forloop.counter0 }} - From {{ days.from_location }} to {{ days.to_location }}</h2>
    {% endfor %}

typeperf "\processor(_total)\% processor time"

does work on Win7, you just need to extract the percent value yourself from the last quoted string.

If you're on .NET 3.5, you can use the following IEnumerable coolness:

Random rnd=new Random();
string[] MyRandomArray = MyArray.OrderBy(x => rnd.Next()).ToArray();    

Edit: and here's the corresponding VB.NET code:

Dim rnd As New System.Random
Dim MyRandomArray = MyArray.OrderBy(Function() rnd.Next()).ToArray()

Second edit, in response to remarks that System.Random "isn't threadsafe" and "only suitable for toy apps" due to returning a time-based sequence: as used in my example, Random() is perfectly thread-safe, unless you're allowing the routine in which you randomize the array to be re-entered, in which case you'll need something like lock (MyRandomArray) anyway in order not to corrupt your data, which will protect rnd as well.

Also, it should be well-understood that System.Random as a source of entropy isn't very strong. As noted in the MSDN documentation, you should use something derived from System.Security.Cryptography.RandomNumberGenerator if you're doing anything security-related. For example:

using System.Security.Cryptography;

...

RNGCryptoServiceProvider rnd = new RNGCryptoServiceProvider();
string[] MyRandomArray = MyArray.OrderBy(x => GetNextInt32(rnd)).ToArray();

...

static int GetNextInt32(RNGCryptoServiceProvider rnd)
    {
        byte[] randomInt = new byte[4];
        rnd.GetBytes(randomInt);
        return Convert.ToInt32(randomInt[0]);
    }

Seems -C option upto tar v2.8.3 does not work consistently on all the platforms (OSes). -C option is said to add directory to the archive but on Mac and Ubuntu it adds absolute path prefix inside generated tar.gz file.

tar target_path/file.tar.gz -C source_path/source_dir

Therefore the consistent and robust solution is to cd in to source_path (parent directory of source_dir) and run

tar target_path/file.tar.gz source_dir

or

tar -cf target_path/file.tar.gz source_dir

in your script. This will remove absolute path prefix in your generated tar.gz file's directory structure.

// In MyClass.h
MyClass<T>& operator+=(const MyClass<T>& classObj);


// In MyClass.cpp
template <class T>
MyClass<T>& MyClass<T>::operator+=(const MyClass<T>& classObj) {
  // ...
  return *this;
}

This is invalid for templates. The full source code of the operator must be in all translation units that it is used in. This typically means that the code is inline in the header.

Edit: Technically, according to the Standard, it is possible to export templates, however very few compilers support it. In addition, you CAN also do the above if the template is explicitly instantiated in MyClass.cpp for all types that are T- but in reality, that normally defies the point of a template.

More edit: I read through your code, and it needs some work, for example overloading operator[]. In addition, typically, I would make the dimensions part of the template parameters, allowing for the failure of + or += to be caught at compile-time, and allowing the type to be meaningfully stack allocated. Your exception class also needs to derive from std::exception. However, none of those involve compile-time errors, they're just not great code.

First of all, the easiest way to run things at startup is to add them to the file /etc/rc.local.

Another simple way is to use @reboot in your crontab. Read the cron manpage for details.

However, if you want to do things properly, in addition to adding a script to /etc/init.d you need to tell ubuntu when the script should be run and with what parameters. This is done with the command update-rc.d which creates a symlink from some of the /etc/rc* directories to your script. So, you'd need to do something like:

update-rc.d yourscriptname start 2

However, real init scripts should be able to handle a variety of command line options and otherwise integrate to the startup process. The file /etc/init.d/README has some details and further pointers.

Two ways:

Use indexes:

double sum = 0;
for(int i = 0; i < m.size(); i++)
    sum += m.get(i);
return sum;

Use the "for each" style:

double sum = 0;
for(Double d : m)
    sum += d;
return sum;

EDIT: This is an extremely primitive answer but I can't delete it because it was accepted. See the answers below for a better solution though

Why not just generate a whitespace string dynamically to insert into the statement.

So if you want them all to start on the 50th character...

String key = "Name =";
String space = "";
for(int i; i<(50-key.length); i++)
{space = space + " ";}
String value = "Bob\n";
System.out.println(key+space+value);

Put all of that in a loop and initialize/set the "key" and "value" variables before each iteration and you're golden. I would also use the StringBuilder class too which is more efficient.

In my case, I was on CentOS 7 and my php installation was pointing to a certificate that was being generated through update-ca-trust. The symlink was /etc/pki/tls/cert.pem pointing to /etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem. This was just a test server and I wanted my self signed cert to work properly. So in my case...

# My root ca-trust folder was here. I coped the .crt file to this location
# and renamed it to a .pem
/etc/pki/ca-trust/source/anchors/self-signed-cert.pem

# Then run this command and it will regenerate the certs for you and
# include your self signed cert file.
update-ca-trust

Then some of my api calls started working as my cert was now trusted. Also if your ca-trust gets updated through yum or something, this will rebuild your root certificates and still include your self signed cert. Run man update-ca-trust for more info on what to do and how to do it. :)

Use .apply() to have the same access to arguments in function b, like this:

function a(){
    b.apply(null, arguments);
}
function b(){
   alert(arguments); //arguments[0] = 1, etc
}
a(1,2,3);?

Designing You Model:

Public class ModelName
{
    ...// Properties
    public IEnumerable<SelectListItem> ListName { get; set; }
}

Prepare and bind List to Model in Controller :

    public ActionResult Index(ModelName model)
    {
        var items = // Your List of data
        model.ListName = items.Select(x=> new SelectListItem() {
                    Text = x.prop,
                    Value = x.prop2
               });
    }

@Html.DropDownListFor(m => Model.prop2,Model.ListName)

You can use the Java enum TimeUnit to perform your math and avoid any hard coded values. Then we can use String.format(String, Object...) and a pair of StringBuilder(s) as well as a DecimalFormat to build the requested output. Something like,

Scanner scanner = new Scanner(System.in);
System.out.println("Please enter a number of seconds:");
String str = scanner.nextLine().replace("\\,", "").trim();
long secondsIn = Long.parseLong(str);
long dayCount = TimeUnit.SECONDS.toDays(secondsIn);
long secondsCount = secondsIn - TimeUnit.DAYS.toSeconds(dayCount);
long hourCount = TimeUnit.SECONDS.toHours(secondsCount);
secondsCount -= TimeUnit.HOURS.toSeconds(hourCount);
long minutesCount = TimeUnit.SECONDS.toMinutes(secondsCount);
secondsCount -= TimeUnit.MINUTES.toSeconds(minutesCount);
StringBuilder sb = new StringBuilder();
sb.append(String.format("%d %s, ", dayCount, (dayCount == 1) ? "day"
        : "days"));
StringBuilder sb2 = new StringBuilder();
sb2.append(sb.toString());
sb2.append(String.format("%02d:%02d:%02d %s", hourCount, minutesCount,
        secondsCount, (hourCount == 1) ? "hour" : "hours"));
sb.append(String.format("%d %s, ", hourCount, (hourCount == 1) ? "hour"
        : "hours"));
sb.append(String.format("%d %s and ", minutesCount,
        (minutesCount == 1) ? "minute" : "minutes"));
sb.append(String.format("%d %s.", secondsCount,
        (secondsCount == 1) ? "second" : "seconds"));
System.out.printf("You entered %s seconds, which is %s (%s)%n",
        new DecimalFormat("#,###").format(secondsIn), sb, sb2);

Which, when I enter 500000 outputs the requested (manual line break added for post) -

You entered 500,000 seconds, which is 5 days, 18 hours, 
53 minutes and 20 seconds. (5 days, 18:53:20 hours)

All you have to do is write an IF condition in the column d like this:

=IF(A1=C1;B1;" ")

After that just apply this formula to all rows above that one.

It might work to use JmDNS on Android: http://jmdns.sourceforge.net/

There are tons of zeroconf-enabled machines out there, so this would enable discovery with more than just Android devices.

You have to use the AppendText method of the textbox directly. If you try to use the Text property, the textbox will not scroll down as new line are appended.

textBox1.AppendText("Hello" + Environment.NewLine);

You can use the wmic command:

wmic path CIM_LogicalDevice where "Description like 'USB%'" get /value

Promise returned from $http can not be binded directly (I dont exactly know why). I'm using wrapping service that works perfectly for me:

.factory('DocumentsList', function($http, $q){
    var d = $q.defer();
    $http.get('/DocumentsList').success(function(data){
        d.resolve(data);
    });
    return d.promise;
});

and bind to it in controller:

function Ctrl($scope, DocumentsList) {
    $scope.Documents = DocumentsList;
    ...
}

UPDATE!:

In Angular 1.2 auto-unwrap promises was removed. See http://docs.angularjs.org/guide/migration#templates-no-longer-automatically-unwrap-promises

I'm using Ubuntu 18.04 LTS. Most of the time, when I change my java version, I also want to use the same javac version.
I use update-alternatives this way, using a java_home alternative instead :

Installation

Install every java version in /opt/java/<version>, for example

~$ ll /opt/java/
total 24
drwxr-xr-x 6 root root 4096 jan. 22 21:14 ./
drwxr-xr-x 9 root root 4096 feb.  7 13:40 ../
drwxr-xr-x  8 stephanecodes stephanecodes 4096 jan.   8  2019 jdk-11.0.2/
drwxr-xr-x  7 stephanecodes stephanecodes 4096 dec.  15  2018 jdk1.8.0_201/

Configure alternatives

~$ sudo update-alternatives --install /opt/java/current java_home /opt/java/jdk-11.0.2/ 100
~$ sudo update-alternatives --install /opt/java/current java_home /opt/java/jdk1.8.0_201 200

Declare JAVA_HOME (In this case, I use a global initialization script for this)

~$ sudo sh -c 'echo export JAVA_HOME=\"/opt/java/current\" >> environment.sh'

Log Out or restart Ubuntu (this will reload /etc/profile.d/environment.sh)

Usage

Change java version

Choose the version you want to use

~$ sudo update-alternatives --config java_home

There are 2 choices for the alternative java_home (providing /opt/java/current).

  Selection    Path                    Priority   Status
------------------------------------------------------------
  0            /opt/java/jdk-11.0.2     200       auto mode
  1            /opt/java/jdk-11.0.2     200       manual mode
* 2            /opt/java/jdk1.8.0_201   100       manual mode

Press <enter> to keep the current choice[*], or type selection number: 

Check version

~$ java -version
openjdk version "11.0.2" 2019-01-15
OpenJDK Runtime Environment 18.9 (build 11.0.2+9)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.2+9, mixed mode)

~$ javac -version
javac 11.0.2

Tip

Add the following line to ~/.bash_aliases file :

alias change-java-version="sudo update-alternatives --config java_home && java -version && javac -version"

Now use the change-java-version command to change java version

For those, who want to do it automatically, I have wrote a little two-lines bash script which does next two things:

1. Looks for all *.aar files and extracts classes.jar from them

2. Renames extracted classes.jar to be like the aar but with a new extension

   find . -name '*.aar' -exec sh -c 'unzip -d `dirname {}` {} classes.jar' \;
   find . -name '*.aar' -exec sh -c 'mv `dirname {}`/classes.jar `echo {} | sed s/aar/jar/g`' \;
   

That's it!

According to pydoc, hasattr(obj, prop) simply calls getattr(obj, prop) and catches exceptions. So, it is just as valid to wrap the attribute access with a try statement and catch AttributeError as it is to use hasattr() beforehand.

a = SomeClass()
try:
    return a.fake_prop
except AttributeError:
    return default_value

From SQL Server 2012 you can use a native pagination in order to have semplicity and best performance:

https://docs.microsoft.com/en-us/sql/t-sql/queries/select-order-by-clause-transact-sql?view=sql-server-ver15#using-offset-and-fetch-to-limit-the-rows-returned

Your query become:

SELECT * FROM Reflow  
WHERE ReflowProcessID = somenumber
ORDER BY ID DESC;
OFFSET 20 ROWS  
FETCH NEXT 20 ROWS ONLY;  

I'm using Maven (SpringBoot application) solution is:

1. Right click project folder
2. Select Maven
3. Select Generate Sources And Update Folders

Then, Intellij automatically import generated sources to project.

I think zeroclipboard is great. this version work with latest Flash 11: http://www.itjungles.com/javascript/javascript-easy-cross-browser-copy-to-clipboard-solution.

To answer the question more generally, the answer is:

select: function( event , ui ) {
    alert( "You selected: " + ui.item.label );
}

Complete example :

$('#test').each(function(i, el) {_x000D_
    var that = $(el);_x000D_
    that.autocomplete({_x000D_
        source: ['apple','banana','orange'],_x000D_
        select: function( event , ui ) {_x000D_
            alert( "You selected: " + ui.item.label );_x000D_
        }_x000D_
    });_x000D_

Laravel - htmlspecialchars() expects parameter 1 to be string, object given.

thank me latter.........................

when you send or get array from contrller or function but try to print as single value or single variable in laravel blade file so it throws an error

->use any think who convert array into string it work.

solution: 1)run the foreach loop and get single single value and print. 2)The implode() function returns a string from the elements of an array. {{ implode($your_variable,',') }}

implode is best way to do it and its 100% work.

Using not a to test whether a is None assumes that the other possible values of a have a truth value of True. However, most NumPy arrays don't have a truth value at all, and not cannot be applied to them.

If you want to test whether an object is None, the most general, reliable way is to literally use an is check against None:

if a is None:
    ...
else:
    ...

This doesn't depend on objects having a truth value, so it works with NumPy arrays.

Note that the test has to be is, not ==. is is an object identity test. == is whatever the arguments say it is, and NumPy arrays say it's a broadcasted elementwise equality comparison, producing a boolean array:

>>> a = numpy.arange(5)
>>> a == None
array([False, False, False, False, False])
>>> if a == None:
...     pass
...
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: The truth value of an array with more than one element is ambiguous.
 Use a.any() or a.all()

On the other side of things, if you want to test whether an object is a NumPy array, you can test its type:

# Careful - the type is np.ndarray, not np.array. np.array is a factory function.
if type(a) is np.ndarray:
    ...
else:
    ...

You can also use isinstance, which will also return True for subclasses of that type (if that is what you want). Considering how terrible and incompatible np.matrix is, you may not actually want this:

# Again, ndarray, not array, because array is a factory function.
if isinstance(a, np.ndarray):
    ...
else:
    ...    

You can add default rating of five stars in side the xml layout

android:rating="5"

Edit:

<RatingBar
        android:id="@+id/rb_vvm"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal"
        android:layout_marginBottom="@dimen/space2"
        android:layout_marginTop="@dimen/space1"
        style="@style/RatingBar"
        android:numStars="5"
        android:stepSize="1"
        android:rating="5" />

I've noticed that if you set the theme in the AndroidManifest, it seems to get rid of that short time where you can see the action bar. So, try adding this to your manifest:

<android:theme="@android:style/Theme.NoTitleBar">

Just add it to your application tag to apply it app-wide.

This essentially requires a range function. A Django feature ticket was raised (https://code.djangoproject.com/ticket/13088) for this but closed as "won't fix" with the following comment.

My impression of this idea is that it is trying to lead to programming in the template. If you have a list of options that need to be rendered, they should be computed in the view, not in the template. If that's as simple as a range of values, then so be it.

They have a good point - Templates are supposed to be very simple representations of the view. You should create the limited required data in the view and pass to the template in the context.

I often use this:

function deepCopy(obj) {
    if(typeof obj !== 'object' || obj === null) {
        return obj;
    }

    if(obj instanceof Date) {
        return new Date(obj.getTime());
    }

    if(obj instanceof Array) {
        return obj.reduce((arr, item, i) => {
            arr[i] = deepCopy(item);
            return arr;
        }, []);
    }

    if(obj instanceof Object) {
        return Object.keys(obj).reduce((newObj, key) => {
            newObj[key] = deepCopy(obj[key]);
            return newObj;
        }, {})
    }
}

I encountered same problem with ORACLE 11G express on Windows. After a long time waiting I got the same error message.

My solution is to make sure the hostname in tnsnames.ora (usually it's not "localhost") and the default hostname in sql developer(usually it's "localhost") same. You can either do this by changing it in the tnsnames.ora, or filling up the same in the sql developer.

Oh, of course you need to reboot all the oracle services (just to be safe).

Hope it helps.

I came across the similar problem again on another machine, but this time above solution doesn't work. After some trying, I found restarting all the oracle related services can fix the problem. Originally when the installation is done, connection can be made. Somehow after several reboot of computer, there is problem. I change all the oracle services with start time as auto. And once I could not connect, I restart them all over again (the core service should be restarted at last order), and works fine.

Some article says it might be due to the MTS problem. Microsoft's problem. Maybe!

Try this:

var setCanvasSize = function() {
canvas.width = window.innerWidth;
canvas.height = window.innerHeight;
}

That is for people who prefer to have the constant on the left side. In most cases having the constant on the left side will prevent NullPointerException to be thrown (or having another nullcheck). For example the String method equals does also a null check. Having the constant on the left, will keep you from writing the additional check. Which, in another way is also performed later. Having the null value on the left is just being consistent.

like:

 String b = null;
 "constant".equals(b);  // result to false
 b.equals("constant");  // NullPointerException
 b != null && b.equals("constant");  // result to false

Check out numpy.count_nonzero.

>>> np.count_nonzero(np.eye(4))

>>> np.count_nonzero([[0,1,7,0,0],[3,0,0,2,19]])

I worked through a number of issues installing all of the following to get devtools to install on Ubuntu 18.04.1.

sudo apt-get install libcurl4-openssl-dev
sudo apt-get install libssl-dev
sudo apt-get install libcurl4-gnutls-dev
sudo apt-get install libxml2-dev

To convert a value returned from a check box in a form to a Boolean property I used the ValueProviderResult's in build converter in a custom ModelBinder.

ValueProviderResult cbValue = bindingContext.ValueProvider.GetValue("CheckBoxName");
bool value = (bool)cbValue.ConvertTo(typeof(bool));

This works everywhere including Safari 5 and Firefox 5 on OS X.

UPDATE: Fx Quantum (54) has no need for the replace, but Safari 11 is still not happy unless you convert as below

var date_test = new Date("2011-07-14 11:23:00".replace(/-/g,"/"));_x000D_
console.log(date_test);

• FindBugs is excellent for this sort of thing.
• PMD (Project Mess Detector) is another tool that can be used.

However, neither can find public static methods that are unused in a workspace. If anyone knows of such a tool then please let me know.

As this is the top post if you google for MySQL high CPU usage or load, I'll add an additional answer:

On the 1st of July 2012, a leap second was added to the current UTC-time to compensate for the slowing rotation of the earth due to the tides. When running ntp (or ntpd) this second was added to your computer's/server's clock. MySQLd does not seem to like this extra second on some OS'es, and yields a high CPU load. The quick fix is (as root):

$ /etc/init.d/ntpd stop
$ date -s "`date`"
$ /etc/init.d/ntpd start

You have to install Python and add it to PATH on Windows. After that you can try:

python `C:/pathToFolder/prog.py`

or go to the files directory and execute:

python prog.py

Please do right click on the project and go to properties. Then go to Build and Packaging. You can see the JAR file location that is produced by defualt setting of netbean in the dist directory.

Have you already looked at the documentation available on http://timgolden.me.uk/python/win32_how_do_i/watch_directory_for_changes.html? If you only need it to work under Windows the 2nd example seems to be exactly what you want (if you exchange the path of the directory with one of the files you want to watch).

Otherwise, polling will probably be the only really platform-independent option.

Note: I haven't tried any of these solutions.

If you are averse to boost, you can use regular old operator>>, along with std::noskipws:

EDIT: updates after testing.

#include <iostream>
#include <iomanip>
#include <vector>
#include <string>
#include <algorithm>
#include <iterator>
#include <sstream>

void split(const std::string& str, std::vector<std::string>& v) {
  std::stringstream ss(str);
  ss >> std::noskipws;
  std::string field;
  char ws_delim;
  while(1) {
    if( ss >> field )
      v.push_back(field);
    else if (ss.eof())
      break;
    else
      v.push_back(std::string());
    ss.clear();
    ss >> ws_delim;
  }
}

int main() {
  std::vector<std::string> v;
  split("hello world  how are   you", v);
  std::copy(v.begin(), v.end(), std::ostream_iterator<std::string>(std::cout, "-"));
  std::cout << "\n";
}

For the record, none of the aforementioned Git Python libraries seem to contain a "git status" equivalent, which is really the only thing I would want since dealing with the rest of the git commands via subprocess is so easy.

I think you can use

sys.exit(0)

You may check it here in the python 2.7 doc:

The optional argument arg can be an integer giving the exit status (defaulting to zero), or another type of object. If it is an integer, zero is considered “successful termination” and any nonzero value is considered “abnormal termination” by shells and the like.

If anyone stumbles across this as it is the first result in google,

remember to specify the filename too in the SaveAs method.

Won't work

file_upload.PostedFile.SaveAs(Server.MapPath(SaveLocation));

You need this:

filename = Path.GetFileName(file_upload.PostedFile.FileName);
file_upload.PostedFile.SaveAs(Server.MapPath(SaveLocation + "\\" + filename));

I assumed the SaveAs method will automatically use the filename uploaded. Kept getting "Access denied" error. Not very descriptive of the actual problem

it work in my case, oldSensor and newSnsor - oldView and newView:

private void replaceSensors(View oldSensor, View newSensor) {
            ViewGroup parent = (ViewGroup) oldSensor.getParent();

            if (parent == null) {
                return;
            }

            int indexOldSensor = parent.indexOfChild(oldSensor);
            int indexNewSensor = parent.indexOfChild(newSensor);
            parent.removeView(oldSensor);
            parent.addView(oldSensor, indexNewSensor);
            parent.removeView(newSensor);
            parent.addView(newSensor, indexOldSensor);
        }

I had to solve a similar problem--I wanted certain styles to only apply to mobile devices in landscape mode. Essentially the fonts and line spacing looked fine in every other context, so I just needed the one exception for mobile landscape. This media query worked perfectly:

@media all and (max-width: 600px) and (orientation:landscape)

• OPTIONS Identifying which HTTP methods a resource supports, e.g. can we DELETE it or update it via a PUT?
• HEAD Checking whether a resource has changed. This is useful when maintaining a cached version of a resource
• HEAD Retrieving metadata about the resource, e.g. its media type or its size, before making a possibly costly retrieval
• HEAD, OPTIONS Testing whether a resource exists and is accessible. For example, validating user-submitted links in an application

Here is nice and concise article about how HEAD and OPTIONS fit into RESTful architecture.

If you have your MySQL server up and running, then you just need a client to connect to it and start practicing. One is the mysql-client, which is a command-line tool, or you can use phpMyAdmin, which is a web-based tool.

You can use the Jquery UI for drag and drop with an additional library that translates mouse events into touch which is what you need, the library I recommend is https://github.com/furf/jquery-ui-touch-punch, with this your drag and drop from Jquery UI should work on touch devises

or you can use this code which I am using, it also converts mouse events into touch and it works like magic.

function touchHandler(event) {
    var touch = event.changedTouches[0];

    var simulatedEvent = document.createEvent("MouseEvent");
        simulatedEvent.initMouseEvent({
        touchstart: "mousedown",
        touchmove: "mousemove",
        touchend: "mouseup"
    }[event.type], true, true, window, 1,
        touch.screenX, touch.screenY,
        touch.clientX, touch.clientY, false,
        false, false, false, 0, null);

    touch.target.dispatchEvent(simulatedEvent);
    event.preventDefault();
}

function init() {
    document.addEventListener("touchstart", touchHandler, true);
    document.addEventListener("touchmove", touchHandler, true);
    document.addEventListener("touchend", touchHandler, true);
    document.addEventListener("touchcancel", touchHandler, true);
}

And in your document.ready just call the init() function

If you know the structure of the json that you're receiving then I'd suggest having a class structure that mirrors what you're receiving in json.

Then you can call its something like this...

AddressMap addressMap = JsonConvert.DeserializeObject<AddressMap>(json);

(Where json is a string containing the json in question)

If you don't know the format of the json you've receiving then it gets a bit more complicated and you'd probably need to manually parse it.

It appears that the use of SAPPLY on a data.frame to convert variables to factors at once does not work as it produces a matrix/ array. My approach is to use LAPPLY instead, as follows.

## let us create a data.frame here

class <- c("7", "6", "5", "3")

cash <- c(100, 200, 300, 150)

height <- c(170, 180, 150, 165)

people <- data.frame(class, cash, height)

class(people) ## This is a dataframe 

## We now apply lapply to the data.frame as follows.

bb <- lapply(people, as.factor) %>% data.frame() 

## The lapply part returns a list which we coerce back to a data.frame

class(bb) ## A data.frame

##Now let us check the classes of the variables 

class(bb$class)

class(bb$height)

class(bb$cash) ## as expected, are all factors. 

In addition to T.J. Crowders answer, I have added some more handlers - including the newer .on(...) handler to the snippet so you can see which events are being hidden and which ones not.

What I also found is that .live() is not only deprecated, but was deleted since jQuery 1.9.x. But the other ones, i.e.
.click, .delegate/.undelegate and .on/.off
are still there.

Also note there is more discussion about this topic here on Stackoverflow.

If you need to fix legacy code that is relying on .live, but you require to use a new version of jQuery (> 1.8.3), you can fix it with this snippet:

// fix if legacy code uses .live, but you want to user newer jQuery library
if (!$.fn.live) {
    // in this case .live does not exist, emulate .live by calling .on
    $.fn.live = function(events, handler) {
      $(this).on(events, null, {}, handler);
    };
}

The intention of the snippet below, which is an extension of T.J.'s script, is that you can try out by yourself instantly what happens if you bind multiple handlers - so please run the snippet and click on the texts below:

As user2357112 mentioned in the comments, you cannot use chained comparisons here. For elementwise comparison you need to use &. That also requires using parentheses so that & wouldn't take precedence.

It would go something like this:

mask = ((50  < df['heart rate']) & (101 > df['heart rate']) & (140 < df['systolic...

In order to avoid that, you can build series for lower and upper limits:

low_limit = pd.Series([90, 50, 95, 11, 140, 35], index=df.columns)
high_limit = pd.Series([160, 101, 100, 19, 160, 39], index=df.columns)

Now you can slice it as follows:

mask = ((df < high_limit) & (df > low_limit)).all(axis=1)
df[mask]

You have enabled CORS and enabled Access-Control-Allow-Origin : * in the server.If still you get GET method working and POST method is not working then it might be because of the problem of Content-Type and data problem.

First AngularJS transmits data using Content-Type: application/json which is not serialized natively by some of the web servers (notably PHP). For them we have to transmit the data as Content-Type: x-www-form-urlencoded

Example :-

        $scope.formLoginPost = function () {
            $http({
                url: url,
                method: "POST",
                data: $.param({ 'username': $scope.username, 'Password': $scope.Password }),
                headers: { 'Content-Type': 'application/x-www-form-urlencoded' }
            }).then(function (response) {
                // success
                console.log('success');
                console.log("then : " + JSON.stringify(response));
            }, function (response) { // optional
                // failed
                console.log('failed');
                console.log(JSON.stringify(response));
            });
        };

Note : I am using $.params to serialize the data to use Content-Type: x-www-form-urlencoded. Alternatively you can use the following javascript function

function params(obj){
    var str = "";
    for (var key in obj) {
        if (str != "") {
            str += "&";
        }
        str += key + "=" + encodeURIComponent(obj[key]);
    }
    return str;
}

and use params({ 'username': $scope.username, 'Password': $scope.Password }) to serialize it as the Content-Type: x-www-form-urlencoded requests only gets the POST data in username=john&Password=12345 form.

Maybe you're not doing it as root?

Try sudo nginx -s reload, if it still doesn't work, you might want to try sudo pkill -HUP nginx.

Write it as below

<script language="javascript">
var visitorName = 'Chuck';
var myOldString = 'Hello username. I hope you enjoy your stay username.';

var myNewString = myOldString.replace('username', visitorName);

document.write('Old String = ' + myOldString);
document.write('<br/>New string = ' + myNewString);
</script>

if("123".search(/^\d+$/) >= 0){
   // its a number
}

There is also this one:

hash = { foo: "bar", baz: "qux" }
hash.map(&:last) #=> ["bar", "qux"]

Why it works:

The & calls to_proc on the object, and passes it as a block to the method.

something {|i| i.foo }
something(&:foo)

It may be "better" to not use attach at all. On the plus side, you can save some typing if you use attach. Let's say your dataset is called mydata and you have variables called v1, v2, and v3. If you don't attach mydata, then you will type mean(mydata$v1) to get the mean of v1. If you do attach mydata, then you will type mean(v1) to get the mean of v1. But, if you don't detach the mydata dataset (every time), you'll get the message about the objects being masked going forward.

Solution 1 (assuming you want to attach):

1. Use detach every time.
2. See Dan Tarr's response if you already have the data attached (and it may be in the global environment several times). Then, in the future, use detach every time.

Solution 2

Don't use attach. Instead, include the dataset name every time you refer to a variable. The form is mydata$v1 (name of data set, dollar sign, name of variable).

As for me, I used solution 1 a lot in the past, but I've moved to solution 2. It's a bit more typing in the beginning, but if you are going to use the code multiple times, it just seems cleaner.

1. On Linux, use the service of "Network Manager" over the DBus.

2. There is also good'ol shell program which can be invoke and the result grabbed (use an exec function under C):

$ /sbin/ifconfig | grep HWaddr

Without FileReader, we can use URL.createObjectURL method to get the DOMString that represents the object ( our image file ).

Don't forget to validate image extension.

<input type="file" id="files" multiple />
<div class="image-preview"></div>

let file_input = document.querySelector('#files');
let image_preview = document.querySelector('.image-preview');

const handle_file_preview = (e) => {
  let files = e.target.files;
  let length = files.length;

  for(let i = 0; i < length; i++) {
      let image = document.createElement('img');
      // use the DOMstring for source
      image.src = window.URL.createObjectURL(files[i]);
      image_preview.appendChild(image);
  }
}

file_input.addEventListener('change', handle_file_preview);

The .Elements operation returns a LIST of XElements - but what you really want is a SINGLE element. Add this:

XElement Contacts = (from xml2 in XMLDoc.Elements("Contacts").Elements("Node")
                    where xml2.Element("ID").Value == variable
                    select xml2).FirstOrDefault();

This way, you tell LINQ to give you the first (or NULL, if none are there) from that LIST of XElements you're selecting.

Implementation of accepted answer for Django:

import hashlib
from django.db import models


class MyModel(models.Model):
    file = models.FileField()  # any field based on django.core.files.File

    def get_hash(self):
        hash = hashlib.md5()
        for chunk in self.file.chunks(chunk_size=8192):
            hash.update(chunk)
        return hash.hexdigest()

You have to find where the Git executable is and then add the folder to the PATH environment variable in file .bash_profile.

Using terminal:

1. Search for Git:

    sudo find / -name git
   

2. Edit the .bash_profile file. Add:

    PATH="<Directory of Git>:$PATH"
   

Git is back :-)

Anyway, I suggest you to install Git using MacPorts. In this way you can easily upgrade your Git instance to the newest release.

Right here: http://jt400.sourceforge.net/

This is what I use for that exact purpose.

EDIT: Usage Examples (minus exceptions):

// Driver initialization
AS400JDBCDriver driver = new com.ibm.as400.access.AS400JDBCDriver();
DriverManager.registerDriver(driver);

// JDBC Connection URL
String url = "jdbc:as400://10.10.10.10" + ";promt=false" // disable GUI prompting by jt400 library

// Get a Connection object (this is used to create statements, etc)
Connection conn = DriverManager.getConnection(url, UserString, PassString);

Hope that helps!

Or, as pointed out in a comment, to keep a reference to the opened workbook:

I think you're going to need separate lines for each segment:

import numpy as np
import matplotlib.pyplot as plt

x, y = np.random.random(size=(2,10))

for i in range(0, len(x), 2):
    plt.plot(x[i:i+2], y[i:i+2], 'ro-')

plt.show()

(The numpy import is just to set up some random 2x10 sample data)

A more complete answer would be it is not possible with ftp(at least the ftp program installed on centos 6).

Since you wanted an un-attended process, "pts"'s answer will work fine.

Do the unattended upload with curl instead of ftp:

curl -u user:password -T file ftp://server/dir/file

%40 doesn't appear to work.

[~]# ftp domain.com
ftp: connect: Connection refused
ftp> quit
[~]# ftp some_user%[email protected]
ftp: some_user%[email protected]: Name or service not known
ftp> quit

All I've got is to open the ftp program and use the domain and enter the user when asked. Usually, a password is required anyway, so the interactive nature probably isn't problematic.

location.hash is not safe for IE , in case of IE ( including IE9 ) , if your page contains iframe , then after manual refresh inside iframe content get location.hash value is old( value for first page load ). while manual retrieved value is different than location.hash so always retrieve it through document.URL

var hash = document.URL.substr(document.URL.indexOf('#')+1) 

The most concise and performant way to display unencoded text is to use textContent property.

Faster than using innerHTML. And that's without taking into account escaping overhead.

document.body.textContent = 'a <b> c </b>';

Use this:

from c in dc.Organization
where SqlMethods.Like(c.Hierarchy, "%/12/%")

I had this same problem when trying to upgrade pm2 to the latest version.

Thanks to sdm's answer I did npm update npm -g and it did the trick for me.

pow only works on floating-point numbers (doubles, actually). If you want to take powers of integers, and the base isn't known to be an exponent of 2, you'll have to roll your own.

Usually the dumb way is good enough.

int power(int base, unsigned int exp) {
    int i, result = 1;
    for (i = 0; i < exp; i++)
        result *= base;
    return result;
 }

Here's a recursive solution which takes O(log n) space and time instead of the easy O(1) space O(n) time:

int power(int base, int exp) {
    if (exp == 0)
        return 1;
    else if (exp % 2)
        return base * power(base, exp - 1);
    else {
        int temp = power(base, exp / 2);
        return temp * temp;
    }
}

Right click on the table and click on Design,then click on column that you want to set default value.

Then in bottom of page in column properties set Default value or binding to : 'getdate()'

You can use pip install scikit-image.

Also see the recommended procedure.

You mentioned that you want the regex to match each of those strings, yet you previously mention that the is 1-2 digits before the decimal?

This will match 1-2 digits followed by a possible decimal, followed by another 1-2 digits but FAIL on your example of .33

\d{1,2}\.?\d{1,2}

This will match 0-2 digits followed by a possible deciaml, followed by another 1-2 digits and match on your example of .33

\d{0,2}\.?\d{1,2}

Not sure exactly which one you're looking for.

You can just use the -R (recursive) flag.

chmod -R 777 /Users/Test/Desktop/PATH

A modern and simple approach: pg-promise:

const pgp = require('pg-promise')(/* initialization options */);

const cn = {
    host: 'localhost', // server name or IP address;
    port: 5432,
    database: 'myDatabase',
    user: 'myUser',
    password: 'myPassword'
};

// alternative:
// var cn = 'postgres://username:password@host:port/database';

const db = pgp(cn); // database instance;

// select and return a single user name from id:
db.one('SELECT name FROM users WHERE id = $1', [123])
    .then(user => {
        console.log(user.name); // print user name;
    })
    .catch(error => {
        console.log(error); // print the error;
    });

// alternative - new ES7 syntax with 'await':
// await db.one('SELECT name FROM users WHERE id = $1', [123]);

I ran into the same issue with CLion 1.2.1 (at the time of writing this answer) after updating Windows 10. It was working fine before I had updated my OS. My OS is installed in C:\ drive and CLion 1.2.1 and Cygwin (64-bit) are installed in D:\ drive.

The issue seems to be with CMake. I am using Cygwin. Below is the short answer with steps I used to fix the issue.

SHORT ANSWER (should be similar for MinGW too but I haven't tried it):

1. Install Cygwin with GCC, G++, GDB and CMake (the required versions)
2. Add full path to Cygwin 'bin' directory to Windows Environment variables
3. Restart CLion and check 'Settings' -> 'Build, Execution, Deployment' to make sure CLion has picked up the right versions of Cygwin, make and gdb
4. Check the project configuration ('Run' -> 'Edit configuration') to make sure your project name appears there and you can select options in 'Target', 'Configuration' and 'Executable' fields.
5. Build and then Run
6. Enjoy

LONG ANSWER:

Below are the detailed steps that solved this issue for me:

1. Uninstall/delete the previous version of Cygwin (MinGW in your case)

2. Make sure that CLion is up-to-date

3. Run Cygwin setup (x64 for my 64-bit OS)

4. Install at least the following packages for Cygwin: gcc g++ make Cmake gdb Make sure you are installing the correct versions of the above packages that CLion requires. You can find the required version numbers at CLion's Quick Start section (I cannot post more than 2 links until I have more reputation points).

5. Next, you need to add Cygwin (or MinGW) to your Windows Environment Variable called 'Path'. You can Google how to find environment variables for your version of Windows

[On Win 10, right-click on 'This PC' and select Properties -> Advanced system settings -> Environment variables... -> under 'System Variables' -> find 'Path' -> click 'Edit']

6. Add the 'bin' folder to the Path variable. For Cygwin, I added: D:\cygwin64\bin

7. Start CLion and go to 'Settings' either from the 'Welcome Screen' or from File -> Settings

8. Select 'Build, Execution, Deployment' and then click on 'Toolchains'

9. Your 'Environment' should show the correct path to your Cygwin installation directory (or MinGW)

10. For 'CMake executable', select 'Use bundled CMake x.x.x' (3.3.2 in my case at the time of writing this answer)

11. 'Debugger' shown to me says 'Cygwin GDB GNU gdb (GDB) 7.8' [too many gdb's in that line ;-)]

12. Below that it should show a checkmark for all the categories and should also show the correct path to 'make', 'C compiler' and 'C++ compiler'

See screenshot: Check all paths to the compiler, make and gdb

13. Now go to 'Run' -> 'Edit configuration'. You should see your project name in the left-side panel and the configurations on the right side

See screenshot: Check the configuration to run the project

14. There should be no errors in the console window. You will see that the 'Run' -> 'Build' option is now active

15. Build your project and then run the project. You should see the output in the terminal window

Hope this helps! Good luck and enjoy CLion.

Replacing all AppSettings

This is the overkill case where you just want to replace an entire section of the web.config. In this case I will replace all AppSettings in the web.config will new settings in web.release.config. This is my baseline web.config appSettings:

<appSettings>
  <add key="KeyA" value="ValA"/>
  <add key="KeyB" value="ValB"/>
</appSettings>

Now in my web.release.config file, I am going to create a appSettings section except I will include the attribute xdt:Transform=”Replace” since I want to just replace the entire element. I did not have to use xdt:Locator because there is nothing to locate – I just want to wipe the slate clean and replace everything.

<appSettings xdt:Transform="Replace">
  <add key="ProdKeyA" value="ProdValA"/>
  <add key="ProdKeyB" value="ProdValB"/>
  <add key="ProdKeyC" value="ProdValC"/>
</appSettings>

Note that in the web.release.config file my appSettings section has three keys instead of two, and the keys aren’t even the same. Now let’s look at the generated web.config file what happens when we publish:

<appSettings>
   <add key="ProdKeyA" value="ProdValA"/>
   <add key="ProdKeyB" value="ProdValB"/>
   <add key="ProdKeyC" value="ProdValC"/>
 </appSettings>

Just as we expected – the web.config appSettings were completely replaced by the values in web.release config. That was easy!

Another solution:

public class DaoTools {
    static public Integer getInteger(ResultSet rs, String strColName) throws SQLException {
        int nValue = rs.getInt(strColName);
        return rs.wasNull() ? null : nValue;
    }
}

You have to use RegExp object if your pattern is string

var xxx = "victoria";
var yyy = "i";
var rgxp = new RegExp(yyy, "g");
alert(xxx.match(rgxp).length);

If pattern is not dynamic string:

var xxx = "victoria";
var yyy = /i/g;
alert(xxx.match(yyy).length);

VideoView myVideo = (VideoView) rootView.findViewById(R.id.definition_video_view);

//Set video name (no extension)
String myVideoName = "my_video";

//Set app package
String myAppPackage = "com.myapp";

//Get video URI from raw directory
Uri myVideoUri = Uri.parse("android.resource://"+myAppPackage+"/raw/"+myVideoName);

//Set the video URI
myVideo.setVideoURI(myVideoUri);

//Play the video
myVideo.start();

Another way num1 = (20*boolVar)+(num1*(not boolVar))

Take a look at the System log in Windows EventViewer (eventvwr from the command line).
You should see entries with source as 'Service Control Manager'. e.g. on my WinXP machine,

Event Type: Information
Event Source:   Service Control Manager
Event Category: None
Event ID:   7036
Date:       7/1/2009
Time:       12:09:43 PM
User:       N/A
Computer:   MyMachine
Description:
The Background Intelligent Transfer Service service entered the running state.

After downloading all the libraries said by ezaoutis, the error message on my windows 10 persisted, reading the wampserver3.1.3 installation requirements, there was a verification tool called check_vcredist.exe , i ran it and it show me all the missing libraries and it's download links, so i finally could install it succesfully.

To start the shell-script 'file.sh':

sh file.sh

bash file.sh

Another option is set executable permission using chmod command:

chmod +x file.sh

Now run .sh file as follows:

./file.sh

The following is building on Eran's code, with a few minor changes. Tested it and it seems to work fine on Firefox 3, IE7.

 var url = "http://www.example.com";
 window.open(url, '_blank');

Since vars passed through url are $_GET vars, you can use filter_input() function:

$id = filter_input(INPUT_GET, 'id', FILTER_SANITIZE_NUMBER_INT);
$othervar = filter_input(INPUT_GET, 'othervar', FILTER_SANITIZE_FULL_SPECIAL_CHARS);

It would store the values of each var and sanitize/validate them too.

import java.util.Map;

public class KeyValue<K, V> implements Map.Entry<K, V>
{
    private K key;
    private V value;

    public KeyValue(K key, V value)
    {
        this.key = key;
        this.value = value;
    }

    public K getKey()
    {
        return this.key;
    }

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

    public K setKey(K key)
    {
        return this.key = key;
    }

    public V setValue(V value)
    {
        return this.value = value;
    }
}

You can display the name of a variable by using the preprocessor. For instance

#include <iostream>
#define quote(x) #x
class one {};
int main(){
    one A;
    std::cout<<typeid(A).name()<<"\t"<< quote(A) <<"\n";
    return 0;
}

outputs

3one    A

on my machine. The # changes a token into a string, after preprocessing the line is

std::cout<<typeid(A).name()<<"\t"<< "A" <<"\n";

Of course if you do something like

void foo(one B){
    std::cout<<typeid(B).name()<<"\t"<< quote(B) <<"\n";
}
int main(){
    one A;
    foo(A);
    return 0;
}

you will get

3one B

as the compiler doesn't keep track of all of the variable's names.

As it happens in gcc the result of typeid().name() is the mangled class name, to get the demangled version use

#include <iostream>
#include <cxxabi.h>
#define quote(x) #x
template <typename foo,typename bar> class one{ };
int main(){
    one<int,one<double, int> > A;
    int status;
    char * demangled = abi::__cxa_demangle(typeid(A).name(),0,0,&status);
    std::cout<<demangled<<"\t"<< quote(A) <<"\n";
    free(demangled);
    return 0;
}

which gives me

one<int, one<double, int> > A

Other compilers may use different naming schemes.

An old question, but I'd like to offer my solution anyway. It's based on acceptance that model objects too require some additional functionality while it's awkward to place it within the models.py. Heavy business logic may be written separately depending on personal taste, but I at least like the model to do everything related to itself. This solution also supports those who like to have all the logic placed within models themselves.

As such, I devised a hack that allows me to separate logic from model definitions and still get all the hinting from my IDE.

The advantages should be obvious, but this lists a few that I have observed:

• DB definitions remain just that - no logic "garbage" attached
• Model-related logic is all placed neatly in one place
• All the services (forms, REST, views) have a single access point to logic
• Best of all: I did not have to rewrite any code once I realised that my models.py became too cluttered and had to separate the logic away. The separation is smooth and iterative: I could do a function at a time or entire class or the entire models.py.

I have been using this with Python 3.4 and greater and Django 1.8 and greater.

app/models.py

....
from app.logic.user import UserLogic

class User(models.Model, UserLogic):
    field1 = models.AnyField(....)
    ... field definitions ...

app/logic/user.py

if False:
    # This allows the IDE to know about the User model and its member fields
    from main.models import User

class UserLogic(object):
    def logic_function(self: 'User'):
        ... code with hinting working normally ...

The only thing I can't figure out is how to make my IDE (PyCharm in this case) recognise that UserLogic is actually User model. But since this is obviously a hack, I'm quite happy to accept the little nuisance of always specifying type for self parameter.

there is a problem in best answer given by ScottKoon

here is it

} else if(el.attachEvent ) {
    myInput.attachEvent('onkeydown',this.keyHandler); /* damn IE hack */
}

Should be

} else if(myInput.attachEvent ) {
    myInput.attachEvent('onkeydown',this.keyHandler); /* damn IE hack */
}

Due to this it didn't work in IE. Hoping that ScottKoon will update code

Forget datalist element that good solution for autocomplete function, but not for combobox feature.

css:

.combobox {
    display: inline-block;
    position: relative;
}

.combobox select {
    display: none;
    position: absolute;
    overflow-y: auto;
}

html:

<div class="combobox">
    <input type="number" name="" value="" min="" max="" step=""/><br/>
    <select size="3">
        <option value="0"> 0</option>
        <option value="25"> 25</option>
        <option value="40"> 40</option>
    </select>
</div>

js (jQuery):

$('.combobox').each(function() {
    var
        $input = $(this).find('input'),
        $select = $(this).find('select');
    function hideSelect() {
        setTimeout(function() {
            if (!$select.is(':focus') && !$input.is(':focus')) {
                $select
                    .hide()
                    .css('z-index', 1);
            }
        }, 20);
    }
    $input
        .focusin(function() {
            if (!$select.is(':visible')) {
                $select
                    .outerWidth($input.outerWidth())
                    .show()
                    .css('z-index', 100);
            }
        })
        .focusout(hideSelect)
        .on('input', function() {
            $select.val('');
        });
    $select
        .change(function() {
            $input.val($select.val());
        })
        .focusout(hideSelect);
});

This works properly even when you use text input instead of number.

There is no way to force EF to improve performance when doing it this way. The problem is that EF executes each insert in separate round trip to the database. Awesome isn't it? Even DataSets supported batch processing. Check this article for some workaround. Another workaround can be using custom stored procedure accepting table valued parameter but you need raw ADO.NET for that.

If the array element is not integer you can use something like below :

$skus  = array('LDRES10','LDRES12','LDRES11');   //sample data

if(!empty($skus)){     
    $sql = "SELECT * FROM `products` WHERE `prodCode` IN ('" . implode("','", $skus) . "') "      
}

Short answer: They are now supported nicely, if you can enable developer mode.

From https://blogs.windows.com/buildingapps/2016/12/02/symlinks-windows-10/

Now in Windows 10 Creators Update, a user (with admin rights) can first enable Developer Mode, and then any user on the machine can run the mklink command without elevating a command-line console.

What drove this change? The availability and use of symlinks is a big deal to modern developers:

Many popular development tools like git and package managers like npm recognize and persist symlinks when creating repos or packages, respectively. When those repos or packages are then restored elsewhere, the symlinks are also restored, ensuring disk space (and the user’s time) isn’t wasted.

Easy to overlook with all the other announcements of the "Creator's update", but if you enable Developer Mode, you can create symlinks without elevated privileges. You might have to re-install git and make sure symlink support is enabled, as it's not by default.

Something like this should work: From Frans Bouma's Blog

SELECT * FROM
(
    SELECT a.*, rownum r__
    FROM
    (
        SELECT * FROM ORDERS WHERE CustomerID LIKE 'A%'
        ORDER BY OrderDate DESC, ShippingDate DESC
    ) a
    WHERE rownum < ((pageNumber * pageSize) + 1 )
)
WHERE r__ >= (((pageNumber-1) * pageSize) + 1)

you can use:

define("PATH_ROOT", dirname(__FILE__));
include_once PATH_ROOT . "/PoliticalForum/headerSite.php";

Alternatively you can do:

Statement stmt = db.prepareStatement(query, Statement.RETURN_GENERATED_KEYS);
numero = stmt.executeUpdate();

ResultSet rs = stmt.getGeneratedKeys();
if (rs.next()){
    risultato=rs.getString(1);
}

But use Sean Bright's answer instead for your scenario.

This is easier than trapping the exception:

import os
if not os.path.exists(...):
    os.makedirs(...)

Disclaimer This approach requires two system calls which is more susceptible to race conditions under certain environments/conditions. If you're writing something more sophisticated than a simple throwaway script running in a controlled environment, you're better off going with the accepted answer that requires only one system call.

UPDATE 2012-07-27

I'm tempted to delete this answer, but I think there's value in the comment thread below. As such, I'm converting it to a wiki.

Java 12 and above

switch (name) {
    case text1, text4 -> // do something ;
    case text2, text3, text 5 -> // do something else ;
    default -> // default case ;
}

You can also assign a value through the switch case expression :

String text = switch (name) {
    case text1, text4 -> "hello" ;
    case text2, text3, text5 -> "world" ;
    default -> "goodbye";
};

"yield" keyword

It allows you to return a value by the switch case expression

String text = switch (name) {
    case text1, text4 ->
        yield "hello";
    case text2, text3, text5 ->
        yield "world";
    default ->
        yield "goodbye";
};

<div class="row">
  <div class="col-xs-6 col-sm-4">Total cost</div>
  <div class="col-xs-6 col-sm-4"></div>
  <div class="clearfix visible-xs-block"></div>
  <div class="col-xs-6 col-sm-4">$42</div>
</div>

That should do the job just ok

I use inf/-inf as initial values to find minimum/maximum value of a measurement. Lets say that you measure temperature with a sensor and you want to keep track of minimum/maximum temperature. The sensor might provide a valid temperature or might be broken. Pseudocode:

# initial value of the temperature
t = float('nan')          
# initial value of minimum temperature, so any measured temp. will be smaller
t_min = float('inf')      
# initial value of maximum temperature, so any measured temp. will be bigger
t_max = float('-inf')     
while True:
    # measure temperature, if sensor is broken t is not changed
    t = measure()     
    # find new minimum temperature
    t_min = min(t_min, t) 
    # find new maximum temperature
    t_max = max(t_max, t) 

The above code works because inf/-inf/nan are valid for min/max operation, so there is no need to deal with exceptions.

As @joris pointed out, iterrows is much slower than itertuples and itertuples is approximately 100 times fater than iterrows, and I tested speed of both methods in a DataFrame with 5027505 records the result is for iterrows, it is 1200it/s, and itertuples is 120000it/s.

If you use itertuples, note that every element in the for loop is a namedtuple, so to get the value in each column, you can refer to the following example code

>>> df = pd.DataFrame({'col1': [1, 2], 'col2': [0.1, 0.2]},
                      index=['a', 'b'])
>>> df
   col1  col2
a     1   0.1
b     2   0.2
>>> for row in df.itertuples():
...     print(row.col1, row.col2)
...
1, 0.1
2, 0.2

Albeit from the useless _T and incorrectly spelled histories. If you are using SQL*Plus, it does not accept create table statements with empty new lines between create table <name> ( and column definitions.

Just as there are printer drivers that do not connect to a printer at all but rather write to a PDF file, analogously there are virtual audio drivers available that do not connect to a physical microphone at all but can pipe input from other sources such as files or other programs.

I hope I'm not breaking any rules by recommending free/donation software, but VB-Audio Virtual Cable should let you create a pair of virtual input and output audio devices. Then you could play an MP3 into the virtual output device and then set the virtual input device as your "microphone". In theory I think that should work.

If all else fails, you could always roll your own virtual audio driver. Microsoft provides some sample code but unfortunately it is not applicable to the older Windows XP audio model. There is probably sample code available for XP too.

What you have is correct. Of course, you'll see that emp1 and item1 have the same pointer value.

private Uri imageUri;
....
Intent intent = new Intent(this, GoogleActivity.class);
intent.putExtra("imageUri", imageUri.toString());
startActivity(intent);
this.finish();

And then you can fetch it like this:

imageUri = Uri.parse(extras.getString("imageUri"));
