Acepted solution implemented in PyQt5

import sys
from PyQt5.QtWidgets import QApplication, QDialog, QFormLayout
from PyQt5.QtWidgets import (QPushButton, QLineEdit)

class Form(QDialog):
    def __init__(self, parent=None):
        super(Form, self).__init__(parent)

        self.le = QLineEdit()
        self.le.setObjectName("host")
        self.le.setText("Host")

        self.pb = QPushButton()
        self.pb.setObjectName("connect")
        self.pb.setText("Connect")
        self.pb.clicked.connect(self.button_click)

        layout = QFormLayout()
        layout.addWidget(self.le)
        layout.addWidget(self.pb)
        self.setLayout(layout)

        self.setWindowTitle("Learning")

    def button_click(self):
        # shost is a QString object
        shost = self.le.text()
        print (shost)


app = QApplication(sys.argv)
form = Form()
form.show()
app.exec_()

If you're using QT Creator 5.6 you can do that like this:

#include <QIntValidator>

ui->myLineEditName->setValidator( new QIntValidator);

I recomend you put that line after ui->setupUi(this);

I hope this helps.

Yes, the biggest difference is that reject is a callback function that gets carried out after the promise is rejected, whereas throw cannot be used asynchronously. If you chose to use reject, your code will continue to run normally in asynchronous fashion whereas throw will prioritize completing the resolver function (this function will run immediately).

An example I've seen that helped clarify the issue for me was that you could set a Timeout function with reject, for example:

new Promise((resolve, reject) => {
  setTimeout(()=>{reject('err msg');console.log('finished')}, 1000);
  return resolve('ret val')
})
.then((o) => console.log("RESOLVED", o))
.catch((o) => console.log("REJECTED", o));

The above could would not be possible to write with throw.

try{
  new Promise((resolve, reject) => {
    setTimeout(()=>{throw new Error('err msg')}, 1000);
    return resolve('ret val')
  })
  .then((o) => console.log("RESOLVED", o))
  .catch((o) => console.log("REJECTED", o));
}catch(o){
  console.log("IGNORED", o)
}

In the OP's small example the difference in indistinguishable but when dealing with more complicated asynchronous concept the difference between the two can be drastic.

If you want to print the picture using imshow() you also execute plt.show()

Instead of adding onSubmit event, you can prevent the default action for submit button.

So, in the following html:

<form name="form" action="insert.php" method="post">
    <input type='submit' />
</form>?

first, prevent submit button action. Then make the ajax call asynchronously, and submit the form when the password is correct.

$('input[type=submit]').click(function(e) {
    e.preventDefault(); //prevent form submit when button is clicked

    var password = $.trim($('#employee_password').val());

     $.ajax({
        type: "POST",
        url: "checkpass.php",
        data: "password="+password,
        success: function(html) {
            var arr=$.parseJSON(html);
            var $form = $('form');
            if(arr == "Successful")
            {    
                $form.submit(); //submit the form if the password is correct
            }
        }
    });
});????????????????????????????????

A different approach.
On the figure() call specify properties or modify the figure handle properties after h = figure().

This creates a full screen figure based on normalized units.
figure('units','normalized','outerposition',[0 0 1 1])

The units property can be adjusted to inches, centimeters, pixels, etc.

See figure documentation.

Sql server unlike oracle does not need commits unless you are using transactions.
Immediatly after your update statement the table will be commited, don't use the commit command in this scenario.

sp_lock

When reading sp_lock information, use the OBJECT_NAME( ) function to get the name of a table from its ID number, for example:

SELECT object_name(16003073)

EDIT :

There is another proc provided by microsoft which reports objects without the ID translation : http://support.microsoft.com/kb/q255596/

See the git-pull man page:

git pull [options] [<repository> [<refspec>...]]

and in the examples section:

Merge into the current branch the remote branch next:

$ git pull origin next

So I imagine you want to do something like:

git pull origin dev

To set it up so that it does this by default while you're on the dev branch:

git branch --set-upstream-to dev origin/dev

The $GLOBALS array can be used instead:

$GLOBALS['a'] = 'localhost';

function body(){

    echo $GLOBALS['a'];
}

From the Manual:

An associative array containing references to all variables which are currently defined in the global scope of the script. The variable names are the keys of the array.

If you have a set of functions that need some common variables, a class with properties may be a good choice instead of a global:

class MyTest
{
    protected $a;

    public function __construct($a)
    {
        $this->a = $a;
    }

    public function head()
    {
        echo $this->a;
    }

    public function footer()
    {
        echo $this->a;
    }
}

$a = 'localhost';
$obj = new MyTest($a);

You may want to consider using SCLAlertView, alternative for UIAlertView or UIAlertController.

UIAlertController only works on iOS 8.x or above, SCLAlertView is a good option to support older version.

github to see the details

example:

let alertView = SCLAlertView()
alertView.addButton("First Button", target:self, selector:Selector("firstButton"))
alertView.addButton("Second Button") {
    print("Second button tapped")
}
alertView.showSuccess("Button View", subTitle: "This alert view has buttons")

You can just use the keywork value to accomplish this.

public int Hour {
    get{
        // Do some logic if you want
        //return some custom stuff based on logic

        // or just return the value
        return value;
    }; set { 
        // Do some logic stuff 
        if(value < MINVALUE){
            this.Hour = 0;
        } else {
            // Or just set the value
            this.Hour = value;
        }
    }
}

One option is to put the subquery in a LEFT JOIN:

select sum ( t.graduates ) - t1.summedGraduates 
from table as t
    left join 
     ( 
        select sum ( graduates ) summedGraduates, id
        from table  
        where group_code not in ('total', 'others' )
        group by id 
    ) t1 on t.id = t1.id
where t.group_code = 'total'
group by t1.summedGraduates 

Perhaps a better option would be to use SUM with CASE:

select sum(case when group_code = 'total' then graduates end) -
    sum(case when group_code not in ('total','others') then graduates end)
from yourtable

SQL Fiddle Demo with both

For my txt file works this way:

let myFileURL = NSBundle.mainBundle().URLForResource("listacomuni", withExtension: "txt")!
let myText = try! String(contentsOfURL: myFileURL, encoding: NSISOLatin1StringEncoding)
print(String(myText))

Select convert(char(8), DATEADD(MINUTE, DATEDIFF(MINUTE, 0, getdate), 0), 108) as Time

will round down seconds to 00

Keeping your code human readable not just machine readable. A lot of devices still can only show 80 characters at a time. Also it makes it easier for people with larger screens to multi-task by being able to set up multiple windows to be side by side.

Readability is also one of the reasons for enforced line indentation.

Let me add another solution:

>> N = 5;
>> f = cellstr(num2str((1:N)', 'f%d'))
f = 
    'f1'
    'f2'
    'f3'
    'f4'
    'f5'

If N is more than two digits long (>= 10), you will start getting extra spaces. Add a call to strtrim(f) to get rid of them.

As a bonus, there is an undocumented built-in function sprintfc which nicely returns a cell arrays of strings:

>> N = 10;
>> f = sprintfc('f%d', 1:N)
f = 
    'f1'    'f2'    'f3'    'f4'    'f5'    'f6'    'f7'    'f8'    'f9'    'f10'

Here is another most easy way to get a custom shape for your image (Image View). It may be helpful for someone. It's just a single line code.

First you need to add a dependency:

dependencies {
    compile 'com.mafstech.libs:mafs-image-shape:1.0.4'   
}

And then just write a line of code like this:

Shaper.shape(context, 
       R.drawable.your_original_image_which_will_be_displayed, 
       R.drawable.shaped_image_your_original_image_will_get_this_images_shape,
       imageView,
       height, 
       weight);   

With CMake, it's generally recommended to do an "out of source" build. Create your CMakeLists.txt in the root of your project. Then from the root of your project:

mkdir Release
cd Release
cmake -DCMAKE_BUILD_TYPE=Release ..
make

And for Debug (again from the root of your project):

mkdir Debug
cd Debug
cmake -DCMAKE_BUILD_TYPE=Debug ..
make

Release / Debug will add the appropriate flags for your compiler. There are also RelWithDebInfo and MinSizeRel build configurations.

You can modify/add to the flags by specifying a toolchain file in which you can add CMAKE_<LANG>_FLAGS_<CONFIG>_INIT variables, e.g.:

set(CMAKE_CXX_FLAGS_DEBUG_INIT "-Wall")
set(CMAKE_CXX_FLAGS_RELEASE_INIT "-Wall")

See CMAKE_BUILD_TYPE for more details.

As for your third question, I'm not sure what you are asking exactly. CMake should automatically detect and use the compiler appropriate for your different source files.

Consider the below example

public class ClastingDemo {

/**
 * @param args
 */
public static void main(String[] args) {
    AOne obj = new Bone();
    ((Bone) obj).method2();
}
}

class AOne {
public void method1() {
    System.out.println("this is superclass");
}
}


 class Bone extends AOne {

public void method2() {
    System.out.println("this is subclass");
}
}

here we create the object of subclass Bone and assigned it to super class AOne reference and now superclass reference does not know about the method method2 in the subclass i.e Bone during compile time.therefore we need to downcast this reference of superclass to subclass reference so as the resultant reference can know about the presence of methods in the subclass i.e Bone

the problem for me was I was trying to use IBM RAD which appears to not work properly for this, I installed Eclipse and now have a different error but I should be able to get past it

You needed to do it like this:

<h2 style="text-align: center;font-family: Tahoma">TITLE</h2>

Hope it helped.

This option comes in curl 7.73.0:

curl --create-dirs -O --output-dir /tmp/receipes https://example.com/pancakes.jpg

Look for an open listener on port 1433 (the default port). If you get any response after creating a tcp connection there, the server's probably up.

import java.util.*;

imports everything within java.util including the Date class.

import java.util.Date;

just imports the Date class.

Doing either of these could not make any difference.

expand "Java Resources" and then 'Libraries' (in eclipse project). make sure that "Apache Tomcat" present.

if not follow- right click on project -> "Build Path" -> "Java Build Path" -> "Add Library" -> select "Server Runtime" -> next -> select "Apache Tomcat -> click finish

clrscr is not standard C function. According to internet, it used to be a thing in old Borland C.
Is clrscr(); a function in C++?

Your code should be contain WHILE before group by and having :

SELECT Email, COUNT(*)

FROM user_log

WHILE Email IS NOT NULL

GROUP BY Email

HAVING COUNT(*) > 1

ORDER BY UpdateDate DESC

Just right-click on the element you want the xpath for and you will see a menu item to copy it. This may not have existed when the OP made his post but it's certainly there now.

hopefully its work

SET foreign_key_checks = 0; DROP TABLE table name; SET foreign_key_checks = 1;

<input type="text" [ngModel]="mymodel" (keypress)="mymodel=$event.target.value"/>
{{mymodel}}

select sequence_owner, sequence_name from dba_sequences;


DBA_SEQUENCES -- all sequences that exist 
ALL_SEQUENCES  -- all sequences that you have permission to see 
USER_SEQUENCES  -- all sequences that you own

Note that since you are, by definition, the owner of all the sequences returned from USER_SEQUENCES, there is no SEQUENCE_OWNER column in USER_SEQUENCES.

You can't set the field having data-type "text". Only because of that thing you are getting this error. Try to change the data-type with int

As of today, there is an official Android-hosted copy of Volley available on JCenter:

compile 'com.android.volley:volley:1.0.0'

This was compiled from the AOSP volley source code.

Combination of Dasha's and MMT solutions:

  Ext.getCmp('yourGridId').getView().ds.reload();

That REALLY depends on what you need that bash script to do!

For example, if the bash script just echoes some output, you could just do

docker run --rm -v $(pwd)/mybashscript.sh:/mybashscript.sh ubuntu bash /mybashscript.sh

Another possibility is that you want the bash script to install some software- say the script to install docker-compose. you could do something like

docker run --rm -v /usr/bin:/usr/bin --privileged -v $(pwd)/mybashscript.sh:/mybashscript.sh ubuntu bash /mybashscript.sh

But at this point you're really getting into having to know intimately what the script is doing to allow the specific permissions it needs on your host from inside the container.

I know this has been answered, but here are a couple of extension methods (for .NET 3.0+) that do the conversion. :)

        /// <summary>
    /// Converts a <see cref="System.Drawing.Image"/> into a WPF <see cref="BitmapSource"/>.
    /// </summary>
    /// <param name="source">The source image.</param>
    /// <returns>A BitmapSource</returns>
    public static BitmapSource ToBitmapSource(this System.Drawing.Image source)
    {
        System.Drawing.Bitmap bitmap = new System.Drawing.Bitmap(source);

        var bitSrc = bitmap.ToBitmapSource();

        bitmap.Dispose();
        bitmap = null;

        return bitSrc;
    }

    /// <summary>
    /// Converts a <see cref="System.Drawing.Bitmap"/> into a WPF <see cref="BitmapSource"/>.
    /// </summary>
    /// <remarks>Uses GDI to do the conversion. Hence the call to the marshalled DeleteObject.
    /// </remarks>
    /// <param name="source">The source bitmap.</param>
    /// <returns>A BitmapSource</returns>
    public static BitmapSource ToBitmapSource(this System.Drawing.Bitmap source)
    {
        BitmapSource bitSrc = null;

        var hBitmap = source.GetHbitmap();

        try
        {
            bitSrc = System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap(
                hBitmap,
                IntPtr.Zero,
                Int32Rect.Empty,
                BitmapSizeOptions.FromEmptyOptions());
        }
        catch (Win32Exception)
        {
            bitSrc = null;
        }
        finally
        {
            NativeMethods.DeleteObject(hBitmap);
        }

        return bitSrc;
    }

and the NativeMethods class (to appease FxCop)

    /// <summary>
/// FxCop requires all Marshalled functions to be in a class called NativeMethods.
/// </summary>
internal static class NativeMethods
{
    [DllImport("gdi32.dll")]
    [return: MarshalAs(UnmanagedType.Bool)]
    internal static extern bool DeleteObject(IntPtr hObject);
}

For simple cases you can also use shift. It treats the argument list like a queue. Each shift throws the first argument out and the index of each of the remaining arguments is decremented.

#this prints all arguments
while test $# -gt 0
do
    echo "$1"
    shift
done

try this

$ cmd='mysql AMORE -u root --password="password" -h localhost -e "select host from amoreconfig"'
$ eval $cmd

1. the best way to delete a record is to find it firstly (if exist in data base in the same time you want to delete it)
2. watch this code

const StudentSequelize = require("../models/studientSequelize");
const StudentWork = StudentSequelize.Student;

const id = req.params.id;
    StudentWork.findByPk(id) // here i fetch result by ID sequelize V. 5
    .then( resultToDelete=>{
        resultToDelete.destroy(id); // when i find the result i deleted it by destroy function
    })
    .then( resultAfterDestroy=>{
        console.log("Deleted :",resultAfterDestroy);
    })
    .catch(err=> console.log(err));

Overhead typically reffers to the amount of extra resources (memory, processor, time, etc.) that different programming algorithms take.

For example, the overhead of inserting into a balanced Binary Tree could be much larger than the same insert into a simple Linked List (the insert will take longer, use more processing power to balance the Tree, which results in a longer percieved operation time by the user).

Kenny is right, just want to clear some things out.

1. Create the file border.xml and put it in the folder res/drawable/

2. add the code

   <shape xmlns:android="http://schemas.android.com/apk/res/android"> 
      <stroke android:width="4dp" android:color="#FF00FF00" /> 
      <solid android:color="#ffffff" /> 
      <padding android:left="7dp" android:top="7dp" 
           android:right="7dp" android:bottom="0dp" /> 
      <corners android:radius="4dp" /> 
   </shape>
   

3. set back ground like android:background="@drawable/border" wherever you want the border

Mine first didn't work cause i put the border.xml in the wrong folder!

try to implement Application_AuthenticateRequest instead of Application_Start.

this method has an instance for HttpContext.Current, unlike Application_Start (which fires very soon in app lifecycle, soon enough to not hold a HttpContext.Current object yet).

hope that helps.

There is an Oracle article I found regarding Java 9 module system

By default, a type in a module is not accessible to other modules unless it’s a public type and you export its package. You expose only the packages you want to expose. With Java 9, this also applies to reflection.

As pointed out in https://stackoverflow.com/a/50251958/134894, the differences between the AccessibleObject#setAccessible for JDK8 and JDK9 are instructive. Specifically, JDK9 added

This method may be used by a caller in class C to enable access to a member of declaring class D if any of the following hold:

• C and D are in the same module.
• The member is public and D is public in a package that the module containing D exports to at least the module containing C.
• The member is protected static, D is public in a package that the module containing D exports to at least the module containing C, and C is a subclass of D.
• D is in a package that the module containing D opens to at least the module containing C. All packages in unnamed and open modules are open to all modules and so this method always succeeds when D is in an unnamed or open module.

which highlights the significance of modules and their exports (in Java 9)

Using union will help in this case.

You can also use join on a condition that always returns true and is not related to data in these tables.See below

select tmd .name,tbc.goals from tblMadrid tmd join tblBarcelona tbc on 1=1;

If you are using Java 8, you could try something like this:

public Set<Number> difference(final Set<Number> set1, final Set<Number> set2){
    final Set<Number> larger = set1.size() > set2.size() ? set1 : set2;
    final Set<Number> smaller = larger.equals(set1) ? set2 : set1;
    return larger.stream().filter(n -> !smaller.contains(n)).collect(Collectors.toSet());
}

I had the same issue when my server free disk space available was 0

You can use the command (there must be ample space for the mysql files)

REPAIR TABLE `<table name>`;

for repairing individual tables

Use following code snippet

It gives following output when executed.

serial port : Communications Port (COM1)
serial port : Communications Port (COM2)

Don't forget to add

using System;
using System.Management;
using System.Windows.Forms;

Also add reference to system.Management (by default it is not available)

C#

private void GetSerialPort()
{

    try
    {
        ManagementObjectSearcher searcher = 
            new ManagementObjectSearcher("root\\CIMV2", 
            "SELECT * FROM Win32_PnPEntity"); 

        foreach (ManagementObject queryObj in searcher.Get())
        {
            if (queryObj["Caption"].ToString().Contains("(COM"))
            {
                Console.WriteLine("serial port : {0}", queryObj["Caption"]);
            }

        }
    }
    catch (ManagementException e)
    {
        MessageBox.Show( e.Message);
    }

}

VB

  Private Sub GetAllSerialPortsName()
        Try
            Dim searcher As New ManagementObjectSearcher("root\CIMV2", "SELECT * FROM Win32_PnPEntity")
            For Each queryObj As ManagementObject In searcher.Get()
                If InStr(queryObj("Caption"), "(COM") > 0 Then
                    Console.WriteLine("serial port : {0}", queryObj("Caption"))
                End If
            Next
        Catch err As ManagementException
            MsgBox(err.Message)
        End Try
    End Sub

Update: You may also check for

if (queryObj["Caption"].ToString().StartsWith("serial port"))

instead of

if (queryObj["Caption"].ToString().Contains("(COM"))

You can have a look at Eclipse color theme, also which has a hell of a lot of options for customizing font, background color, etc.

Completeness

You need to check both $mysqli and $statement. If they are false, you need to output $mysqli->error or $statement->error respectively.

Efficiency

For simple scripts that may terminate, I use simple one-liners that trigger a PHP error with the message. For a more complex application, an error warning system should be activated instead, for example by throwing an exception.

Usage example 1: Simple script

# This is in a simple command line script
$mysqli = new mysqli('localhost', 'buzUser', 'buzPassword');
$q = "UPDATE foo SET bar=1";
($statement = $mysqli->prepare($q)) or trigger_error($mysqli->error, E_USER_ERROR);
$statement->execute() or trigger_error($statement->error, E_USER_ERROR);

Usage example 2: Application

# This is part of an application
class FuzDatabaseException extends Exception {
}

class Foo {
  public $mysqli;
  public function __construct(mysqli $mysqli) {
    $this->mysqli = $mysqli;
  }
  public function updateBar() {
    $q = "UPDATE foo SET bar=1";
    $statement = $this->mysqli->prepare($q);
    if (!$statement) {
      throw new FuzDatabaseException($mysqli->error);
    }

    if (!$statement->execute()) {
      throw new FuzDatabaseException($statement->error);
    }
  }
}

$foo = new Foo(new mysqli('localhost','buzUser','buzPassword'));
try {
  $foo->updateBar();
} catch (FuzDatabaseException $e)
  $msg = $e->getMessage();
  // Now send warning emails, write log
}

Use the std::getline() from <string>.

 istream & getline(istream & is,std::string& str)

So, for your case it would be:

std::getline(read,x);

In SQL SERVER it is BIT, though it allows NULL to be stored

ALTER TABLE person add  [AdminApproved] BIT default 'FALSE';

Also there are other mistakes in your query

1. When you alter a table to add column no need to mention column keyword in alter statement

2. For adding default constraint no need to use SET keyword

3. Default value for a BIT column can be ('TRUE' or '1') / ('FALSE' or 0). TRUE or FALSE needs to mentioned as string not as Identifier

Use text-align:justify on the container, this way it will work no matter how many elements you have in your list (you don't have to work out % widths for each list item

    #nav {_x000D_
        text-align: justify;_x000D_
        min-width: 500px;_x000D_
    }_x000D_
    #nav:after {_x000D_
        content: '';_x000D_
        display: inline-block;_x000D_
        width: 100%;_x000D_
    }_x000D_
    #nav li {_x000D_
        display: inline-block;_x000D_
    }

<ul id="nav">_x000D_
    <li><a href="#">HOME</a></li>_x000D_
    <li><a href="#">ABOUT</a></li>_x000D_
    <li><a href="#">BASIC SERVICES</a></li>_x000D_
    <li><a href="#">OUR STAFF</a></li>_x000D_
    <li><a href="#">CONTACT US</a></li>_x000D_
</ul>

FIDDLE

The best way is to simply reset the password by connecting with a domain/local admin (so you may need help from your system administrators), but this only works if SQL Server was set up to allow local admins (these are now left off the default admin group during setup).

If you can't use this or other existing methods to recover / reset the SA password, some of which are explained here:

• Disaster Recovery: What to do when the SA account password is lost in SQL Server 2005
• Is there a way I can retrieve sa password in sql server 2005
• How to recover SA password on Microsoft SQL Server 2008 R2

Then you could always backup your important databases, uninstall SQL Server, and install a fresh instance.

You can also search for less scrupulous ways to do it (e.g. there are password crackers that I am not enthusiastic about sharing).

As an aside, the login properties for sa would never say Windows Authentication. This is by design as this is a SQL Authentication account. This does not mean that Windows Authentication is disabled at the instance level (in fact it is not possible to do so), it just doesn't apply for a SQL auth account.

I wrote a tip on using PSExec to connect to an instance using the NT AUTHORITY\SYSTEM account (which works < SQL Server 2012), and a follow-up that shows how to hack the SqlWriter service (which can work on more modern versions):

• Recover access to a SQL Server instance
• More on Recovering Access to a SQL Server Instance

And some other resources:

• Connect to SQL Server When System Administrators Are Locked Out

• Leveraging Service SIDs to Logon to SQL Server Instances with Sysadmin Privileges

Here are 3 examples:

$(document).on('click', 'ul li a', function (e) {_x000D_
    e.preventDefault();_x000D_
_x000D_
    var example1 = $(this).parents('ul:first').attr('id');_x000D_
    $('#results').append('<p>Result from example 1: <strong>' + example1 + '</strong></p>');_x000D_
_x000D_
    var example2 = $(this).parents('ul:eq(0)').attr('id');_x000D_
    $('#results').append('<p>Result from example 2: <strong>' + example2 + '</strong></p>');_x000D_
  _x000D_
    var example3 = $(this).closest('ul').attr('id');_x000D_
    $('#results').append('<p>Result from example 3: <strong>' + example3 + '</strong></p>');_x000D_
  _x000D_
  _x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
<ul id ="myList">_x000D_
  <li><a href="www.example.com">Click here</a></li>_x000D_
</ul>_x000D_
_x000D_
<div id="results">_x000D_
  <h1>Results:</h1>_x000D_
</div>

Let me know whether it was helpful.

Try like

var hasName = 'N';
if (name == "true") {
    hasName = 'Y';
}

Or even try with ternary operator like

var hasName = (name == "true") ? "Y" : "N" ;

Even simply you can try like

var hasName = (name) ? "Y" : "N" ;

Since name has either Yes or No but iam not sure with it.

Use Guava transform method as below,

List intList = Lists.transform(stringList, Integer::parseInt);

Go to the Preferences tab (menu File → Settings), and then search as “word wrap”. The following animated image is helpful too.

I know that is a old question, but...

You can also use this in your class:

@Autowired
private HttpServletRequest context;

And this will provide the current instance of HttpServletRequest for you use on your method.

Try just =COUNTIF(A2:A51,"iPad")

There are many ways.

<!-- Probably the most common: -->
<div style="text-align: center;"><a href="...">Link</a></div>

<!-- Getting crafty... -->
<a href="..." style="display: block; text-align: center;">Link</a></div>

There are probably other ways too, but these three are probably the most common.

Apart from "readability", no. They're functionally equivalent.

_{("Readability" is in quotes because I hate == false and find ! much more readable. But others don't.)}

When you have custom logging logic, it is rather annoying to be forced either not to log application_start or to have to let an exception occurs in the logger (even if handled).

It appears that rather than testing for Request availability, you can test for Handler availability: when there is no Request, it would be strange to still have a request handler. And testing for Handler does not raise that dreaded Request is not available in this context exception.

So you may change your code to:

var currContext = HttpContext.Current;
if (currContext != null && currContext.Handler != null)

Beware, in the context of a http module, Handler may not be defined though Request and Response are defined (I have seen that in BeginRequest event). So if you need request/response logging in a custom http module, my answer may not be suitable.

For dynamic 2D charts, I have been using JChart2D. It's fast, simple, and being updated regularly. The author has been quick to respond to my one bug report and few feature requests. We, at our company, prefer it over JFreeChart because it was designed for dynamic use, unlike JFreeChart.

The solution given by Ash Clarke for subdomains works great, but please note that you need to include the document.domain = "mydomain.com"; in both the head of the iframe page and the head of the parent page, as stated in the link same origin policy checks

An important extension to the same origin policy implemented for JavaScript DOM access (but not for most of the other flavors of same-origin checks) is that two sites sharing a common top-level domain may opt to communicate despite failing the "same host" check by mutually setting their respective document.domain DOM property to the same qualified, right-hand fragment of their current host name. For example, if http://en.example.com/ and http://fr.example.com/ both set document.domain to "example.com", they would be from that point on considered same-origin for the purpose of DOM manipulation.

Max out the value by comparing each one to the max_item. In the first if, every time the value of max_item changes it gives its previous value to second_max. To tightly couple the two second if ensures the boundary

def secondmax(self, list):
    max_item = list[0]
    second_max = list[1]
    for item in list:
        if item > max_item:
            second_max =  max_item
            max_item = item
        if max_item < second_max:
            max_item = second_max
    return second_max

To write a ZIP file, you use a ZipOutputStream. For each entry that you want to place into the ZIP file, you create a ZipEntry object. You pass the file name to the ZipEntry constructor; it sets the other parameters such as file date and decompression method. You can override these settings if you like. Then, you call the putNextEntry method of the ZipOutputStream to begin writing a new file. Send the file data to the ZIP stream. When you are done, call closeEntry. Repeat for all the files you want to store. Here is a code skeleton:

FileOutputStream fout = new FileOutputStream("test.zip");
ZipOutputStream zout = new ZipOutputStream(fout);
for all files
{
    ZipEntry ze = new ZipEntry(filename);
    zout.putNextEntry(ze);
    send data to zout;
    zout.closeEntry();
}
zout.close();

You can try yourself:

>>> import pandas as pd
>>> from StringIO import StringIO
>>> s = """1, 2
... 3, 4
... 5, 6"""
>>> pd.read_csv(StringIO(s), skiprows=[1], header=None)
   0  1
0  1  2
1  5  6
>>> pd.read_csv(StringIO(s), skiprows=1, header=None)
   0  1
0  3  4
1  5  6

System.Diagnostics.Process.Start(BatchFileName, Parameters);

I know this will work for batch file and parameters, but no ideas how to get the results in C#. Usually, the outputs are defined in the batch file.

Try this:

<td style="position:relative;">
    <div style="position:absolute;top:0;bottom:0;width:100%;"></div>
</td>

An ioctl, which means "input-output control" is a kind of device-specific system call. There are only a few system calls in Linux (300-400), which are not enough to express all the unique functions devices may have. So a driver can define an ioctl which allows a userspace application to send it orders. However, ioctls are not very flexible and tend to get a bit cluttered (dozens of "magic numbers" which just work... or not), and can also be insecure, as you pass a buffer into the kernel - bad handling can break things easily.

An alternative is the sysfs interface, where you set up a file under /sys/ and read/write that to get information from and to the driver. An example of how to set this up:

static ssize_t mydrvr_version_show(struct device *dev,
        struct device_attribute *attr, char *buf)
{
    return sprintf(buf, "%s\n", DRIVER_RELEASE);
}

static DEVICE_ATTR(version, S_IRUGO, mydrvr_version_show, NULL);

And during driver setup:

device_create_file(dev, &dev_attr_version);

You would then have a file for your device in /sys/, for example, /sys/block/myblk/version for a block driver.

Another method for heavier use is netlink, which is an IPC (inter-process communication) method to talk to your driver over a BSD socket interface. This is used, for example, by the WiFi drivers. You then communicate with it from userspace using the libnl or libnl3 libraries.

Add this to your python script.

import os
os.system("exec /path/to/another/script")

This executes that command as if it were typed into the shell.

If you don't need typesafe, just bring block to a new separated file and change the extension to .js,.jsx

As per the documentation: This allows you to switch from the default ASCII to other encodings such as UTF-8, which the Python runtime will use whenever it has to decode a string buffer to unicode.

This function is only available at Python start-up time, when Python scans the environment. It has to be called in a system-wide module, sitecustomize.py, After this module has been evaluated, the setdefaultencoding() function is removed from the sys module.

The only way to actually use it is with a reload hack that brings the attribute back.

Also, the use of sys.setdefaultencoding() has always been discouraged, and it has become a no-op in py3k. The encoding of py3k is hard-wired to "utf-8" and changing it raises an error.

I suggest some pointers for reading:

Simple answer: You can't. An array is fixed size in Java. You'll want to use a List<String>.

Alternatively, you could create an array of fixed size and put things in it:

String[] array = new String[2];
array[0] = "Hello";
array[1] = "World!";

Yes, super() (lowercase) calls a constructor of the parent class. You can include arguments: super(foo, bar)

There is also a super keyword, that you can use in methods to invoke a method of the superclass

A quick google for "Java super" results in this

var word = " testWord ";   //add here word or space and test

var x = $.trim(word);

if(x.length > 0)
    alert('word');
else
    alert('spaces');

I am able to achieve the necessary code coverage exclusions by updating jacoco-maven-plugin configuration in pom.xml

                    </excludes>
                </configuration>
            </plugin>

this configuration excludes the GlobalExceptionHandler.java and ErrorResponse.java in the jacoco coverage.

And the following two lines does the same for sonar coverage .

    <sonar.exclusions> **/*GlobalExceptionHandler*.*, **/*ErrorResponse*.</sonar.exclusions>
        <sonar.coverage.exclusions> **/*GlobalExceptionHandler*.*, **/*ErrorResponse*.* </sonar.coverage.exclusions>

If you're open to using libraries, try installing forked-path (with either easy_install or pip).

Then you can do:

from path import path
s = path(filename).bytes()

This library is fairly new, but it's a fork of a library that's been floating around Python for years and has been used quite a bit. Since I found this library years ago, I very seldom use os.path or open() any more.

Instead of the JSON document, you can update the ObjectMapper object like below :

ObjectMapper mapper = new ObjectMapper();
mapper.configure(DeserializationFeature.ACCEPT_SINGLE_VALUE_AS_ARRAY, true);

Another regex solution:

string.replace(/\D/g,'');  //remove the non-Numeric

Similarly, you can

string.replace(/\W/g,'');  //remove the non-alphaNumeric

In RegEX, the symbol '\' would make the letter following it a template: \w -- alphanumeric, and \W - Non-AlphaNumeric, negates when you capitalize the letter.

For those searching for a solution to the issue of the ripple effect not working on a programmatically created CardView (or in my case custom view which extends CardView) being shown in a RecyclerView, the following worked for me. Basically declaring the XML attributes mentioned in the other answers declaratively in the XML layout file doesn't seem to work for a programmatically created CardView, or one created from a custom layout (even if root view is CardView or merge element is used), so they have to be set programmatically like so:

private class MadeUpCardViewHolder extends RecyclerView.ViewHolder {
    private MadeUpCardView cardView;

    public MadeUpCardViewHolder(View v){
        super(v);

        this.cardView = (MadeUpCardView)v;

        // Declaring in XML Layout doesn't seem to work in RecyclerViews
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            int[] attrs = new int[]{R.attr.selectableItemBackground};
            TypedArray typedArray = context.obtainStyledAttributes(attrs);
            int selectableItemBackground = typedArray.getResourceId(0, 0);
            typedArray.recycle();

            this.cardView.setForeground(context.getDrawable(selectableItemBackground));
            this.cardView.setClickable(true);
        }
    }
}

Where MadeupCardView extends CardView Kudos to this answer for the TypedArray part.

Delete has been recently added in Hive version 0.14 Deletes can only be performed on tables that support ACID Below is the link from Apache .

Alternatively, you could cherry-pick the commit-id onto your branch.

<commit-id> made in detached head state

git checkout master

git cherry-pick <commit-id>

No temporary branches, no merging.

Visually you can open "SQL Server Configuration Manager" and check properties of "Network Configuration":

Using function in typescript

openWindow(){
    //you may choose to deduct some value from current screen size
    let height = window.screen.availHeight-100;
    let width = window.screen.availWidth-150;
    window.open("http://your_url",`width=${width},height=${height}`);
}

The above suggestions trashed the layout of my table so I ended up using:

td {
  min-width: 30px;
  max-width: 30px;
  overflow: hidden;
}

This is horrible to maintain but was easier than re-doing all the existing css for the site. Hope it helps someone else.

When you want to remove a string, rather than replace it you can use String#delete (or its mutator equivalent String#delete!), e.g.:

x = "foo\nfoo"
x.delete!("\n")

x now equals "foofoo"

In this specific case String#delete is more readable than gsub since you are not actually replacing the string with anything.

Guid.NewGuid() will create one

I work on normalize.css.

The main differences are:

1. Normalize.css preserves useful defaults rather than "unstyling" everything. For example, elements like sup or sub "just work" after including normalize.css (and are actually made more robust) whereas they are visually indistinguishable from normal text after including reset.css. So, normalize.css does not impose a visual starting point (homogeny) upon you. This may not be to everyone's taste. The best thing to do is experiment with both and see which gels with your preferences.

2. Normalize.css corrects some common bugs that are out of scope for reset.css. It has a wider scope than reset.css, and also provides bug fixes for common problems like: display settings for HTML5 elements, the lack of font inheritance by form elements, correcting font-size rendering for pre, SVG overflow in IE9, and the button styling bug in iOS.

3. Normalize.css doesn't clutter your dev tools. A common irritation when using reset.css is the large inheritance chain that is displayed in browser CSS debugging tools. This is not such an issue with normalize.css because of the targeted stylings.

4. Normalize.css is more modular. The project is broken down into relatively independent sections, making it easy for you to potentially remove sections (like the form normalizations) if you know they will never be needed by your website.

5. Normalize.css has better documentation. The normalize.css code is documented inline as well as more comprehensively in the GitHub Wiki. This means you can find out what each line of code is doing, why it was included, what the differences are between browsers, and more easily run your own tests. The project aims to help educate people on how browsers render elements by default, and make it easier for them to be involved in submitting improvements.

I've written in greater detail about this in an article about normalize.css

Here is the best way I found for Python 2:

def inplace_change(file,old,new):
        fin = open(file, "rt")
        data = fin.read()
        data = data.replace(old, new)
        fin.close()

        fin = open(file, "wt")
        fin.write(data)
        fin.close()

An example:

inplace_change('/var/www/html/info.txt','youtub','youtube')

I usually start with the following when styling definition lists as tables:

dt,
dd{
    /* Override browser defaults */
    display: inline;
    margin: 0;
}

dt  {
    clear:left;
    float:left;
    line-height:1; /* Adjust this value as you see fit */
    width:33%; /* 1/3 the width of the parent. Adjust this value as you see fit */
}

dd {
    clear:right;
    float: right;
    line-height:1; /* Adjust this value as you see fit */
    width:67%; /* 2/3 the width of the parent. Adjust this value as you see fit */
}

You can use length:

if($("#one").length) { // 0 == false; >0 == true
    alert('yes');
}

The docs indicate that numpy.correlate is not what you are looking for:

numpy.correlate(a, v, mode='valid', old_behavior=False)[source]
  Cross-correlation of two 1-dimensional sequences.
  This function computes the correlation as generally defined in signal processing texts:
     z[k] = sum_n a[n] * conj(v[n+k])
  with a and v sequences being zero-padded where necessary and conj being the conjugate.

Instead, as the other comments suggested, you are looking for a Pearson correlation coefficient. To do this with scipy try:

from scipy.stats.stats import pearsonr   
a = [1,4,6]
b = [1,2,3]   
print pearsonr(a,b)

This gives

(0.99339926779878274, 0.073186395040328034)

You can also use numpy.corrcoef:

import numpy
print numpy.corrcoef(a,b)

This gives:

[[ 1.          0.99339927]
 [ 0.99339927  1.        ]]

$("#element").removeAttr("class").addClass("yourClass");

If you use jQuery, u can do it like this:

<form action="example" method="post" id="loginform">
  ...
  <input id="btnin" type="button" value="login"/>
  <input id="btnreg" type="button" value="regist"/>
</form>

And js will be:

$("#btnin").click(function(){
   $("#loginform").attr("action", "user_login");
   $("#loginform").submit();
}
$("#btnreg").click(function(){
   $("#loginform").attr("action", "user_regist");
   $("#loginform").submit();
}

How about something like this?

user_input = raw_input("Enter three numbers separated by commas: ")

input_list = user_input.split(',')
numbers = [float(x.strip()) for x in input_list]

(You would probably want some error handling too)

I needed to do this as a test case, to see if new classes had been added to the code. This is what I did

final static File rootFolder = new File(SuperClass.class.getProtectionDomain().getCodeSource().getLocation().getPath());
private static ArrayList<String> files = new ArrayList<String>();
listFilesForFolder(rootFolder); 

@Test(timeout = 1000)
public void testNumberOfSubclasses(){
    ArrayList<String> listSubclasses = new ArrayList<>(files);
    listSubclasses.removeIf(s -> !s.contains("Superclass.class"));
    for(String subclass : listSubclasses){
        System.out.println(subclass);
    }
    assertTrue("You did not create a new subclass!", listSubclasses.size() >1);     
}

public static void listFilesForFolder(final File folder) {
    for (final File fileEntry : folder.listFiles()) {
        if (fileEntry.isDirectory()) {
            listFilesForFolder(fileEntry);
        } else {
            files.add(fileEntry.getName().toString());
        }
    }
}

Try this awesome ink-html library

import print from 'ink-html'
// const print = require('ink-html').default

// js
print(window.querySelector('#printable'))
// Vue.js
print(this.$refs.printable.$el)

When creating the AlertDialog you can set a theme to use.

Example - Creating the Dialog

AlertDialog.Builder builder = new AlertDialog.Builder(this, R.style.MyAlertDialogStyle);
builder.setTitle("AppCompatDialog");
builder.setMessage("Lorem ipsum dolor...");
builder.setPositiveButton("OK", null);
builder.setNegativeButton("Cancel", null);
builder.show();

styles.xml - Custom style

<style name="MyAlertDialogStyle" parent="Theme.AppCompat.Light.Dialog.Alert">
    <!-- Used for the buttons -->
    <item name="colorAccent">#FFC107</item>
    <!-- Used for the title and text -->
    <item name="android:textColorPrimary">#FFFFFF</item>
    <!-- Used for the background -->
    <item name="android:background">#4CAF50</item>
</style>

Result

Edit

In order to change the Appearance of the Title, you can do the following. First add a new style:

<style name="MyTitleTextStyle">
    <item name="android:textColor">#FFEB3B</item>
    <item name="android:textAppearance">@style/TextAppearance.AppCompat.Title</item>
</style>

afterwards simply reference this style in your MyAlertDialogStyle:

<style name="MyAlertDialogStyle" parent="Theme.AppCompat.Light.Dialog.Alert">
    ...
    <item name="android:windowTitleStyle">@style/MyTitleTextStyle</item>
</style>

This way you can define a different textColor for the message via android:textColorPrimary and a different for the title via the style.

I tried a lot many things, but my drop down was inside a table and I was not able to perform a simple select operation. Only the below solution worked. Here I am highlighting drop down elem and pressing down arrow until getting the desired value -

        #identify the drop down element
        elem = browser.find_element_by_name(objectVal)
        for option in elem.find_elements_by_tag_name('option'):
            if option.text == value:
                break

            else:
                ARROW_DOWN = u'\ue015'
                elem.send_keys(ARROW_DOWN)

Using hr created two lines for me, one solid and one dotted.

I found that this worked quite well:

div {
border-top: 1px dotted #cccccc;
color: #ffffff;
background-color: #ffffff;
height: 1px;
width: 95%;
}

Plus, because you can make the width a percentage, it will always have some space on either side (even when you resize the window).

While Migrating Android application package file (APK) to Android App Bundle (AAB), publishing app into Play Store i faced this issue and got resolved like this below...

When building .aab file you get prompted for the location to store key export path as below:

In second image you find Encrypted key export path Location where our .pepk will store in the specific folder while generating .aab file.

Once you log in to the Google Play Console with play store credential: select your project from left side choose App Signing option Release Management>>App Signing

you will find the Google App Signing Certification window ACCEPT it.

After that you will find three radio button select **

Upload a key exported from Android Studio radio button

**, it will expand you APP SIGNING PRIVATE KEY button as below

click on the button and choose the .pepk file (We Stored while generating .aab file as above)

Read the all other option and submit.

Adapting Salar's answer to JSX and React, I noticed that React Select doesn't behave just like an <input/> field regarding validation. Apparently, several workarounds are needed to show only the custom message and to keep it from showing at inconvenient times.

I've raised an issue here, if it helps anything. Here is a CodeSandbox with a working example, and the most important code there is reproduced here:

Hello.js

import React, { Component } from "react";
import SelectValid from "./SelectValid";

export default class Hello extends Component {
  render() {
    return (
      <form>
        <SelectValid placeholder="this one is optional" />
        <SelectValid placeholder="this one is required" required />
        <input
          required
          defaultValue="foo"
          onChange={e => e.target.setCustomValidity("")}
          onInvalid={e => e.target.setCustomValidity("foo")}
        />
        <button>button</button>
      </form>
    );
  }
}

SelectValid.js

import React, { Component } from "react";
import Select from "react-select";
import "react-select/dist/react-select.css";

export default class SelectValid extends Component {
  render() {
    this.required = !this.props.required
      ? false
      : this.state && this.state.value ? false : true;
    let inputProps = undefined;
    let onInputChange = undefined;
    if (this.props.required) {
      inputProps = {
        onInvalid: e => e.target.setCustomValidity(this.required ? "foo" : "")
      };
      onInputChange = value => {
        this.selectComponent.input.input.setCustomValidity(
          value
            ? ""
            : this.required
              ? "foo"
              : this.selectComponent.props.value ? "" : "foo"
        );
        return value;
      };
    }
    return (
      <Select
        onChange={value => {
          this.required = !this.props.required ? false : value ? false : true;
          let state = this && this.state ? this.state : { value: null };
          state.value = value;
          this.setState(state);
          if (this.props.onChange) {
            this.props.onChange();
          }
        }}
        value={this && this.state ? this.state.value : null}
        options={[{ label: "yes", value: 1 }, { label: "no", value: 0 }]}
        placeholder={this.props.placeholder}
        required={this.required}
        clearable
        searchable
        inputProps={inputProps}
        ref={input => (this.selectComponent = input)}
        onInputChange={onInputChange}
      />
    );
  }
}

I think a better way to solve this would be to use the datetime callable:

from datetime import datetime

date = models.DateField(default=datetime.now)

Note that no parenthesis were used. If you used parenthesis you would invoke the now() function just once (when the model is created). Instead, you pass the callable as an argument, thus being invoked everytime an instance of the model is created.

Credit to Django Musings. I've used it and works fine.

if you open localhost/phpmyadmin you will find a tab called "User accounts". There you can define all your users that can access the mysql database, set their rights and even limit from where they can connect.

• From the PHP Web site, referring to the empty() function:

Returns FALSE if var has a non-empty and non-zero value.

That’s a good thing to know. In other words, everything from NULL, to 0 to “” will return TRUE when using the empty() function.

• Here is the description of what the isset() function returns:

Returns TRUE if var exists; FALSE otherwise.

In other words, only variables that don’t exist (or, variables with strictly NULL values) will return FALSE on the isset() function. All variables that have any type of value, whether it is 0, a blank text string, etc. will return TRUE.

Some CSS :

table td, table td * {
    vertical-align: top;
}

Maybe you want to use CSS "clip-path" (Works with transparency and background)

"clip-path" reference: https://developer.mozilla.org/en-US/docs/Web/CSS/clip-path

Example:

/* With percent */_x000D_
.element-percent {_x000D_
  background: red;_x000D_

  height: 48px;_x000D_
  display: inline-block;_x000D_
  _x000D_
  clip-path: polygon(0 0, 100% 0%, 75% 100%, 0% 100%);_x000D_

This will do it in SQL Server:

DECLARE @listStr VARCHAR(MAX)
SELECT @listStr = COALESCE(@listStr+',' ,'') + Convert(nvarchar(8),DepartmentId)
FROM Table
SELECT @listStr

This solution intends to run currently open file in node and show output in VSCode.

I had the same question and found newly introduced tasks useful for this specific use case. It is a little hassle, but here is what I did:

Create a .vscode directory in the root of you project and create a tasks.json file in it. Add this task definition to the file:

{
    "version": "0.1.0",
    "command": "node",
    "isShellCommand": true,
    "args": [
        "--harmony"
    ],

    "tasks": [
        {
            "taskName": "runFile",
            "suppressTaskName": true,
            "showOutput": "always",
            "problemMatcher": "$jshint",
            "args": ["${file}"]
        }
    ]
}

Then you can: press F1 > type `run task` > enter > select `runFile` > enter to run your task, but I found it easier to add a custom key binding for opening tasks lists.

To add the key binding, in VSCode UI menu, go 'Code' > 'Preferences' > 'Keyboard Shortcuts'. Add this to your keyboard shortcuts:

{
    "key": "cmd+r",
    "command": "workbench.action.tasks.runTask"
}

Of course you can select whatever you want as key combination.

UPDATE:

Assuming you are running the JavaScript code to test it, you could mark your task as a test task by setting its isTestCommand property to true and then you can bind a key to the workbench.action.tasks.test command for a single-action invocation.

In other words, your tasks.json file would now contain:

{
    "version": "0.1.0",
    "command": "node",
    "isShellCommand": true,
    "args": [
        "--harmony"
    ],

    "tasks": [
        {
            "taskName": "runFile",
            "isTestCommand": true,
            "suppressTaskName": true,
            "showOutput": "always",
            "problemMatcher": "$jshint",
            "args": ["${file}"]
        }
    ]
}

...and your keybindings.json file would now contain:

{
    "key": "cmd+r",
    "command": "workbench.action.tasks.test"
}

To follow up on Robert's answer, this is even later, but you can use a static helper class to make the runtime check once only per type:

public bool Foo<T>() where T : class
{
    FooHelper<T>.Foo();
}

private static class FooHelper<TInterface> where TInterface : class
{
    static FooHelper()
    {
        if (!typeof(TInterface).IsInterface)
            throw // ... some exception
    }
    public static void Foo() { /*...*/ }
}

I also note that your "should work" solution does not, in fact, work. Consider:

public bool Foo<T>() where T : IBase;
public interface IBase { }
public interface IActual : IBase { string S { get; } }
public class Actual : IActual { public string S { get; set; } }

Now there's nothing stopping you from calling Foo thus:

Foo<Actual>();

The Actual class, after all, satisfies the IBase constraint.

This is not obscure, it's the C++ initialization list syntax

Basically, in your case, x will be initialized with _x, y with _y, z with _z.

Try:

function initSlider(){
    $('.references').slick({
        dots: false,
        infinite: true,
        speed: 300,
        slidesToShow: 1,
        autoplay: true,
        prevArrow: '<div class="slick-prev"><i class="fa fa-chevron-left"></i></div>',
        nextArrow: '<div class="slick-next"><i class="fa fa-chevron-right"></i></div>'
    });
}

$(document).on('ready', function () {
    initSlider();
});

Also just to be sure, make sure that you include the JS file for the slider after you include jQuery and before you include the code above to initialise.

You can do this in the Admin section. It's explained in the documentation.

https://docs.djangoproject.com/en/dev/ref/contrib/redirects/

UPDATE 2

@Override
    protected void onResume() {
        super.onResume();
        mUserNameEdit.requestFocus();

        mUserNameEdit.postDelayed(new Runnable() {

            @Override
            public void run() {
                // TODO Auto-generated method stub
                InputMethodManager keyboard = (InputMethodManager)
                getSystemService(Context.INPUT_METHOD_SERVICE);
                keyboard.showSoftInput(mUserNameEdit, 0);
            }
        },200); //use 300 to make it run when coming back from lock screen
    }

I tried very hard and found out a solution ... whenever a new activity starts then keyboard cant open but we can use Runnable in onResume and it is working fine so please try this code and check...

UPDATE 1

add this line in your AppLogin.java

mUserNameEdit.requestFocus();

and this line in your AppList.java

listview.requestFocus()'

after this check your application if it is not working then add this line in your AndroidManifest.xml file

<activity android:name=".AppLogin" android:configChanges="keyboardHidden|orientation"></activity>
<activity android:name=".AppList" android:configChanges="keyboard|orientation"></activity>

ORIGINAL ANSWER

 InputMethodManager imm = (InputMethodManager)this.getSystemService(Service.INPUT_METHOD_SERVICE);

for hide keyboard

 imm.hideSoftInputFromWindow(ed.getWindowToken(), 0); 

for show keyboard

 imm.showSoftInput(ed, 0);

for focus on EditText

 ed.requestFocus();

where ed is EditText

@JorgeGRC Thanks for your answer. One thing though, the "maybe" part is very important. If you do have parameter(s), you must include it/them on your template as well and be sure to specify your locals e.g. updateFn({msg: "Directive Args"}.

In case you want to compare strings, write the following JSTL :

<c:choose>
    <c:when test="${myvar.equals('foo')}">
        ...
    </c:when>
    <c:when test="${myvar.equals('bar')}">
        ...
    </c:when>
    <c:otherwise>
        ...
    </c:otherwise>
</c:choose>

One simple way would be to configure button with lambda like the following syntax:

button['command'] = lambda arg1 = local_var1, arg2 = local_var2 : function(arg1, arg2)

Since the version 22.1.0, the class ActionBarActivity is deprecated. You should use AppCompatActivity.

Tony is a pure genius. However to achieve even better auto-completion try setting the triggers to this:

ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz =.(!+-*/~,[{@#$%^&

(specifically aranged in order of usage for faster performance :)

place after input

<script type="text/javascript">document.formname.inputname.focus();</script>

Once I encounterred a build which could not be stopped by the "Script Console". Finally I solved the problem with these steps:

ssh onto the jenkins server
cd to .jenkins/jobs/<job-name>/builds/
rm -rf <build-number>
restart jenkins

Here is A simple function with scandir& array_filter that do the job. filter needed files using regex. I removed . .. and hidden files like .htaccess, you can also customise output using <ul> and colors and also customise errors in case no scan or empty dirs!.

function getAllContentOfLocation($loc)
{   
    $scandir = scandir($loc);

    $scandir = array_filter($scandir, function($element){

        return !preg_match('/^\./', $element);

    });

    if(empty($scandir)) echo '<li style="color:red">Empty Dir</li>';

    foreach($scandir as $file){

        $baseLink = $loc . DIRECTORY_SEPARATOR . $file;

        echo '<ol>';
        if(is_dir($baseLink))
        {
            echo '<li style="font-weight:bold;color:blue">'.$file.'</li>';
            getAllContentOfLocation($baseLink);

        }else{
            echo '<li>'.$file.'</li>';
        }
        echo '</ol>';
    }
}
//Call function and set location that you want to scan 
getAllContentOfLocation('../app');

I'm way late here, but after reading @Greg Pettit's answer and a couple of blogs or other SO questions I unfortunately can't remember I decided to just make a couple of dataTables plugins to deal with this.

I put them on bitbucket in a Mercurial repo. I follwed the fnSetFilteringDelay plugin and just changed the comments and code inside, as I've never made a plugin for anything before. I made 2, and feel free to use them, contribute to them, or provide suggestions.

• dataTables.TruncateCells - truncates each cell in a column down to a set number of characters, replacing the last 3 with an ellipses, and puts the full pre-truncated text in the cell's title attributed.

• dataTables.BreakCellText - attempts to insert a break character every X, user defined, characters in each cell in the column. There are quirks regarding cells that contain both spaces and hyphens, you can get some weird looking results (like a couple of characters straggling after the last inserted
  character). Maybe someone can make that more robust, or you can just fiddle with the breakPos for the column to make it look alright with your data.

for disable sorting on any column in datatable use the following

aoColumnDefs: [{ "aTargets": [ 0 ], "bSortable": false}],

it means "aTargets": [ 0 ] is the column id starting from 0

so in your case it becomes:

 $(".tableSort").dataTable({
        aaSorting: [[0, 'asc']],
        aoColumnDefs: [
            { "aTargets": [ -1 ], "bSortable": false},
        ]
    });

My personal preference is to put it in ~/opt/local/android-sdk-mac or /Developer/android-sdk-mac the latter being where Xcode and all the Apple Dev tools are held.

choicely, you could use a your Folder/index.cshtml as a masterpage then add section scripts. Then, in your layout you have:

@RenderSection("scripts", required: false) 

and your index.cshtml:

@section scripts{
     @Scripts.Render("~/Scripts/file.js")
}

and it will working over all your partialviews. It work for me

Try putting the height into one of the cells, like this:

<table class="tableContainer" cellspacing="10px">
 <tr>
  <td style="height:15px;">NHS Number</td>
  <td>&#160;</td>

Note however, that you won't be able to make the cell smaller than the content requires it to be. In that case you would have to make the text smaller first.

An anonymous class is extending or implementing while creating its object For example :

Interface in = new InterFace()
{

..............

}

Here anonymous class is implementing Interface.

Class cl = new Class(){

.................

}

here anonymous Class is extending a abstract Class.

ODBC and OLE DB are two competing data access technologies. Specifically regarding SQL Server, Microsoft has promoted both of them as their Preferred Future Direction - though at different times.

ODBC

ODBC is an industry-wide standard interface for accessing table-like data. It was primarily developed for databases and presents data in collections of records, each of which is grouped into a collection of fields. Each field has its own data type suitable to the type of data it contains. Each database vendor (Microsoft, Oracle, Postgres, …) supplies an ODBC driver for their database.

There are also ODBC drivers for objects which, though they are not database tables, are sufficiently similar that accessing data in the same way is useful. Examples are spreadsheets, CSV files and columnar reports.

OLE DB

OLE DB is a Microsoft technology for access to data. Unlike ODBC it encompasses both table-like and non-table-like data such as email messages, web pages, Word documents and file directories. However, it is procedure-oriented rather than object-oriented and is regarded as a rather difficult interface with which to develop access to data sources. To overcome this, ADO was designed to be an object-oriented layer on top of OLE DB and to provide a simpler and higher-level – though still very powerful – way of working with it. ADO’s great advantage it that you can use it to manipulate properties which are specific to a given type of data source, just as easily as you can use it to access those properties which apply to all data source types. You are not restricted to some unsatisfactory lowest common denominator.

While all databases have ODBC drivers, they don’t all have OLE DB drivers. There is however an interface available between OLE and ODBC which can be used if you want to access them in OLE DB-like fashion. This interface is called MSDASQL (Microsoft OLE DB provider for ODBC).

SQL Server Data Access Technologies

Since SQL Server is (1) made by Microsoft, and (2) the Microsoft database platform, both ODBC and OLE DB are a natural fit for it.

ODBC

Since all other database platforms had ODBC interfaces, Microsoft obviously had to provide one for SQL Server. In addition to this, DAO, the original default technology in Microsoft Access, uses ODBC as the standard way of talking to all external data sources. This made an ODBC interface a sine qua non. The version 6 ODBC driver for SQL Server, released with SQL Server 2000, is still around. Updated versions have been released to handle the new data types, connection technologies, encryption, HA/DR etc. that have appeared with subsequent releases. As of 09/07/2018 the most recent release is v13.1 “ODBC Driver for SQL Server”, released on 23/03/2018.

OLE DB

This is Microsoft’s own technology, which they were promoting strongly from about 2002 – 2005, along with its accompanying ADO layer. They were evidently hoping that it would become the data access technology of choice. (They even made ADO the default method for accessing data in Access 2002/2003.) However, it eventually became apparent that this was not going to happen for a number of reasons, such as:

1. The world was not going to convert to Microsoft technologies and away from ODBC;
2. DAO/ODBC was faster than ADO/OLE DB and was also thoroughly integrated into MS Access, so wasn’t going to die a natural death;
3. New technologies that were being developed by Microsoft, specifically ADO.NET, could also talk directly to ODBC. ADO.NET could talk directly to OLE DB as well (thus leaving ADO in a backwater), but it was not (unlike ADO) solely dependent on it.

For these reasons and others, Microsoft actually deprecated OLE DB as a data access technology for SQL Server releases after v11 (SQL Server 2012). For a couple of years before this point, they had been producing and updating the SQL Server Native Client, which supported both ODBC and OLE DB technologies. In late 2012 however, they announced that they would be aligning with ODBC for native relational data access in SQL Server, and encouraged everybody else to do the same. They further stated that SQL Server releases after v11/SQL Server 2012 would actively not support OLE DB!

This announcement provoked a storm of protest. People were at a loss to understand why MS was suddenly deprecating a technology that they had spent years getting them to commit to. In addition, SSAS/SSRS and SSIS, which were MS-written applications intimately linked to SQL Server, were wholly or partly dependent on OLE DB. Yet another complaint was that OLE DB had certain desirable features which it seemed impossible to port back to ODBC – after all, OLE DB had many good points.

In October 2017, Microsoft relented and officially un-deprecated OLE DB. They announced the imminent arrival of a new driver (MSOLEDBSQL) which would have the existing feature set of the Native Client 11 and would also introduce multi-subnet failover and TLS 1.2 support. The driver was released in March 2018.

Tried all the solutions here, but nothing seemed to work. After hours of digging I found this blog post and like magic everything works. I had to make little adjustments so here is the modified version. Tested with Docker version 17.06.0-ce, build 02c1d87.

Once developers really start containerising their applications, they often generate a large number of images and quickly fill up the 20GB hard drive space allocated to the Docker virtual machine by default. To make sure the Docker virtual machine has plenty of disk space, we should resize /dev/sda1 to a number that is more reasonable.

1. Download GParted Live CD/USB/HD/PXE Bootable Image.

2. Stop the Docker virtual machine docker-machine stop default.

3. Boot2Docker package installer ships with a VMDK volume, which VirtualBox’s native tools cannot resize. In order to resize the Docker disk volume, first clone the VDI volume from the default VMDK volume vboxmanage clonehd /full/path/to/disk.vmdk /full/path/to/disk_resized.vdi --format VDI --variant Standard.

4. Resize the newly cloned VDI volume to the desired capacity. We recommend at least 64GB vboxmanage modifyhd /full/path/to/disk_resized.vdi --resize <size in MB>.
5. Launch the VirtualBox application, select default VM and click on the “Settings” gear on top.
6. Click on the “Storage” icon. Remove the default VMDK volume.
7. Add a new IDE controller.
8. Mount the GParted ISO via the “Add CD/DVD Device” option.
9. Mount the cloned VDI volume via the “Add CD/DVD Device” option.
10. If you are running Docker on a computer with a solid-state hard drive, please make sure the “Solid-state Drive” option is selected for the cloned VDI volume.
11. Click on the “Start” icon to boot up the Docker virtual machine, which will launch the GParted ISO. Select “GParted Live (Default settings)”.
12. Set the policy for handling keymaps to “Don’t touch keymap”.
13. Set language preference to option “33”, which maps to “US English”.
14. Select option “1” to run “Forcevideo” and configure X manually.
15. Keep the default resolution of “1024×760” by selecting option “2”.
16. Keep the default “vesa” as the VGA card.
17. Keep the default colour depth of “24” by selecting option “0”.
18. Once GParted launches, click on the “Resize/Move” icon.
19. Set the new disk volume size to desired size by dragging the slider. In this example, the maximum size is 127,035MB. Click on the “Resize/Move” button to start the process.
20. Confirm the resizing operation by clicking on the “Apply” button.
21. Power off the machine after the resizing operation finishes.
22. Remove the GParted ISO.
23. Log into the Docker virtual machine to verify that the volume resizing was successful by starting machine docker-machine start default
24. If you experience network issues, restart the docker-machine

I happen to have implemented it, and it works in most cases. Since it is long, I put it in a file here.

The idea is to find the location of the class source file which is available in most cases (a known exception are JVM class files -- as far as I've tested). If the code is in a directory, scan through all files and only spot class files. If the code is in a JAR file, scan all entries.

This method can only be used when:

1. You have a class that is in the same package you want to discover, This class is called a SeedClass. For example, if you want to list all classes in 'java.io', the seed class may be java.io.File.

2. Your classes are in a directory or in a JAR file it has source file information (not source code file, but just source file). As far as I've tried, it work almost 100% except the JVM class (those classes come with the JVM).

3. Your program must have permission to access ProtectionDomain of those classes. If your program is loaded locally, there should be no problem.

I've tested the program only for my regular usage, so it may still have problem.

I hope this helps.

Do one thing, go to properties of database select files and increase initial size of database and set primary filegroup as autoincremented. Restart sql server.

You will be able to use database as earlier.

Don't forget to run cmd as admin.

Using a subshell substitution to parse the words undoes all the work you are doing to put spaces together.

Try instead:

cat CSV_file | sed -n 1'p' | tr ',' '\n' | while read word; do
    echo $word
done

That also increases parallelism. Using a subshell as in your question forces the entire subshell process to finish before you can start iterating over the answers. Piping to a subshell (as in my answer) lets them work in parallel. This matters only if you have many lines in the file, of course.

Try the following:

url($_GET['q'], array('absolute' => true));

To print those numbers in C do the following:

printf("%d", addNumbers(a,b));

I made a procedure that execute a FOREACH with CURSOR for any table.

Example of use:

CREATE TABLE #A (I INT, J INT)
INSERT INTO #A VALUES (1, 2), (2, 3)

Okay, I realized the answer myself, after I had to think about other people's answers. :P

var htmlContent = ... // a response via AJAX containing HTML
var e = document.createElement('div');
e.setAttribute('style', 'display: none;');
e.innerHTML = htmlContent;
document.body.appendChild(e);
var htmlConvertedIntoDom = e.lastChild.childNodes; // the HTML converted into a DOM element :), now let's remove the
document.body.removeChild(e);

INSERT OR REPLACE will replace the other fields to default value.

sqlite> CREATE TABLE Book (
  ID     INTEGER PRIMARY KEY AUTOINCREMENT,
  Name   TEXT,
  TypeID INTEGER,
  Level  INTEGER,
  Seen   INTEGER
);

sqlite> INSERT INTO Book VALUES (1001, 'C++', 10, 10, 0);

sqlite> SELECT * FROM Book;
1001|C++|10|10|0

sqlite> INSERT OR REPLACE INTO Book(ID, Name) VALUES(1001, 'SQLite');

sqlite> SELECT * FROM Book;
1001|SQLite|||

If you want to preserve the other field

• Method 1

sqlite> SELECT * FROM Book;
1001|C++|10|10|0

sqlite> INSERT OR IGNORE INTO Book(ID) VALUES(1001);
sqlite> UPDATE Book SET Name='SQLite' WHERE ID=1001;

sqlite> SELECT * FROM Book;
1001|SQLite|10|10|0

• Method 2

Using UPSERT (syntax was added to SQLite with version 3.24.0 (2018-06-04))

INSERT INTO Book (ID, Name)
  VALUES (1001, 'SQLite')
  ON CONFLICT (ID) DO
  UPDATE SET Name=excluded.Name;

The excluded. prefix equal to the value in VALUES ('SQLite').

just put #login-box before <h2>Welcome</h2> will be ok.

<div class='container'>

This way of get only date without time

DateTime date = DateTime.Now;
string Strdateonly = date.ToString("d");

Output = 5/16/2015

I am pretty sure this is one of the things due to change in Python 3.0 with perhaps bin() to go with hex() and oct().

EDIT: lbrandy's answer is correct in all cases.

i am using v3.1.3 and i had to use data('DateTimePicker') like this

var fromE = $( "#" + fromInput );
var toE = $( "#" + toInput );
$('.form-datepicker').datetimepicker(dtOpts);

$('.form-datepicker').on('change', function(e){
   var isTo = $(this).attr('name') === 'to';

   $( "#" + ( isTo ? fromInput : toInput  ) )
      .data('DateTimePicker')[ isTo ? 'setMaxDate' : 'setMinDate' ](moment($(this).val(), 'DD/MM/YYYY'))
});

You can also use the Record type in typescript :

export interface nameInterface { 
    propName : Record<string, otherComplexInterface> 
}

For anyone trying to this in react. There is a slight difference.

// Document of 8.5 inch width and 11 inch high
new jsPDF('p', 'in', [612, 792]);

or

// Document of 8.5 inch width and 11 inch high
new jsPDF({
        orientation: 'p', 
        unit: 'in', 
        format: [612, 792]
});

When i tried the @Aidiakapi solution the pages were tiny. For a difference size take size in inches * 72 to get the dimensions you need. For example, i wanted 8.5 so 8.5 * 72 = 612. This is for [email protected].

Shortest Yet!

<button onclick="history.go(-1);">Go back</button>

http://jsfiddle.net/qXrbx/

I prefer the .go(-number) method as then, for 1 or many 'backs' there's only 1 method to use/remember/update/search for, etc.

Also, using a tag for a back button seems more appropriate than tags with names and types...

"Global" JavaScript variables are members of the window object. You could access the reference as a member of the window object.

var v = "initialized";

function byref(ref) {
  window[ref] = "changed by ref";
}

byref((function(){for(r in window){if(window[r]===v){return(r);}}})());
// It could also be called like... byref('v');
console.log(v); // outputs changed by ref

Note, the above example will not work for variables declared within a function.

Many screencasts displaying an iPhone application simply use the iPhone Simulator, which is one option.

You can also take screenshots on the phone by quickly pressing the menu and the power/sleep button at the same time. The image is then saved to your "Camera Roll" and easily transferable to the computer

The other way is only possible with a Jailbroken phone - Veency is a VNC server for the iPhone, which you can connect to with a regular VNC client.

A CLASSPATH entry is either a directory at the head of a package hierarchy of .class files, or a .jar file. If you're expecting ./lib to include all the .jar files in that directory, it won't. You have to name them explicitly.

pre-made code attached here. you can use it by just copying and pasting in your code:

Here is an updated answer

var newFunc = oldFunc.bind({}); //clones the function with '{}' acting as it's new 'this' parameter

However .bind is a modern ( >=iE9 ) feature of JavaScript (with a compatibility workaround from MDN)

Notes

1. It does not clone the function object additional attached properties, including the prototype property. Credit to @jchook

2. The new function this variable is stuck with the argument given on bind(), even on new function apply() calls. Credit to @Kevin

function oldFunc() {
  console.log(this.msg);
}
var newFunc = oldFunc.bind({ msg: "You shall not pass!" }); // this object is binded
newFunc.apply({ msg: "hello world" }); //logs "You shall not pass!" instead

3. Bound function object, instanceof treats newFunc/oldFunc as the same. Credit to @Christopher

(new newFunc()) instanceof oldFunc; //gives true
(new oldFunc()) instanceof newFunc; //gives true as well
newFunc == oldFunc; //gives false however

TL:DR; return promises from you actions only when necessary, but DRY chaining the same actions.

For a long time I also though that returning actions contradicts the Vuex cycle of uni-directional data flow.

But, there are EDGE CASES where returning a promise from your actions might be "necessary".

Imagine a situation where an action can be triggered from 2 different components, and each handles the failure case differently. In that case, one would need to pass the caller component as a parameter to set different flags in the store.

Dumb example

Page where the user can edit the username in navbar and in /profile page (which contains the navbar). Both trigger an action "change username", which is asynchronous. If the promise fails, the page should only display an error in the component the user was trying to change the username from.

Of course it is a dumb example, but I don't see a way to solve this issue without duplicating code and making the same call in 2 different actions.

Edit: I've just seen the edit to clarify that the original question was for the reduction of iterations / code and that's all well and good as an exercise, but in real-world situations you're going to want the fastest implementation, regardless of how cool the underlying LINQ looks.

Here's my Utils method for iterating through the loaded types. It handles regular classes as well as interfaces, and the excludeSystemTypes option speeds things up hugely if you are looking for implementations in your own / third-party codebase.

public static List<Type> GetSubclassesOf(this Type type, bool excludeSystemTypes) {
    List<Type> list = new List<Type>();
    IEnumerator enumerator = Thread.GetDomain().GetAssemblies().GetEnumerator();
    while (enumerator.MoveNext()) {
        try {
            Type[] types = ((Assembly) enumerator.Current).GetTypes();
            if (!excludeSystemTypes || (excludeSystemTypes && !((Assembly) enumerator.Current).FullName.StartsWith("System."))) {
                IEnumerator enumerator2 = types.GetEnumerator();
                while (enumerator2.MoveNext()) {
                    Type current = (Type) enumerator2.Current;
                    if (type.IsInterface) {
                        if (current.GetInterface(type.FullName) != null) {
                            list.Add(current);
                        }
                    } else if (current.IsSubclassOf(type)) {
                        list.Add(current);
                    }
                }
            }
        } catch {
        }
    }
    return list;
}

It's not pretty, I'll admit.

Looking this up in my handy Harbison & Steele....

Determine the maximum width of fields.

int max_width, value_to_print;
max_width = 8;
value_to_print = 1000;
printf("%*d\n", max_width, value_to_print);

Bear in mind that max_width must be of type int to work with the asterisk, and you'll have to calculate it based on how much space you're going to want to have. In your case, you'll have to calculate the maximum width of the largest number, and add 4.

The Groovy way to do this is

def list = []
list << new MyType(...)

which creates a list and uses the overloaded leftShift operator to append an item

See the Groovy docs on Lists for lots of examples.

Or you can use like this. This may be faster.

int iFindNo = 14;
int j = dataGridView1.Rows.Count-1;
int iRowIndex = -1;
for (int i = 0; i < Convert.ToInt32(dataGridView1.Rows.Count/2) +1; i++)
{
    if (Convert.ToInt32(dataGridView1.Rows[i].Cells[0].Value) == iFindNo)
    {
        iRowIndex = i;
        break;
    }
    if (Convert.ToInt32(dataGridView1.Rows[j].Cells[0].Value) == iFindNo)
    {
        iRowIndex = j;
        break;
    }
    j--;
}
if (iRowIndex != -1)
    MessageBox.Show("Index is " + iRowIndex.ToString());
else
    MessageBox.Show("Index not found." );

Add a prop 'key' to the rendering root component of the list.

<ScrollView>
      <List>
          {this.state.nationalities.map((prop, key) => {
             return (
               <ListItem key={key}>
                  <Text>{prop.name}</Text>
               </ListItem>
             );
          })}
      </List>
</ScrollView>

With the help of jquery it can be done as follows.

$("#color").prop('disabled', true);

Color.parseColor("#rrggbb")

instead of #rrggbb you should be using hex values 0 to F for rr, gg and bb:

e.g. Color.parseColor("#000000") or Color.parseColor("#FFFFFF")

Source

From documentation:

public static int parseColor (String colorString):

Parse the color string, and return the corresponding color-int. If the string cannot be parsed, throws an IllegalArgumentException exception. Supported formats are: #RRGGBB #AARRGGBB 'red', 'blue', 'green', 'black', 'white', 'gray', 'cyan', 'magenta', 'yellow', 'lightgray', 'darkgray', 'grey', 'lightgrey', 'darkgrey', 'aqua', 'fuschia', 'lime', 'maroon', 'navy', 'olive', 'purple', 'silver', 'teal'

So I believe that if you are using #rrggbb you are getting IllegalArgumentException in your logcat

Source

Alternative:

Color mColor = new Color();
mColor.red(redvalue);
mColor.green(greenvalue);
mColor.blue(bluevalue);
li.setBackgroundColor(mColor);

Source

Both versions are working, either with concatenation by using the escaped single quote character (\'), or with concatenation by enclosing the single quote character within double quotes ("'").

The author of the question did not notice that there was an extra single quote (') at the end of his last escaping attempt:

alias rxvt='urxvt -fg'\''#111111'\'' -bg '\''#111111'\''
           ¦         ¦??|       ¦??¦     ¦??¦       ¦??¦
           +-STRING--+??+-STRIN-+??+-STR-+??+-STRIN-+??¦
                      ??         ??       ??         ??¦
                      ??         ??       ??         ??¦
                      +---------------?---------------+¦
                          All escaped single quotes    ¦
                                                       ¦
                                                       ?

As you can see in the previous nice piece of ASCII/Unicode art, the last escaped single quote (\') is followed by an unnecessary single quote ('). Using a syntax-highlighter like the one present in Notepad++ can prove very helpful.

The same is true for another example like the following one:

alias rc='sed '"'"':a;N;$!ba;s/\n/, /g'"'"
alias rc='sed '\'':a;N;$!ba;s/\n/, /g'\'

These two beautiful instances of aliases show in a very intricate and obfuscated way how a file can be lined down. That is, from a file with a lot of lines you get only one line with commas and spaces between the contents of the previous lines. In order to make sense of the previous comment, the following is an example:

$ cat Little_Commas.TXT
201737194
201802699
201835214

$ rc Little_Commas.TXT
201737194, 201802699, 201835214

As an alternate you can use reactive forms. Here is an example: https://stackblitz.com/edit/angular-pqb2xx

Template

<form [formGroup]="mainForm" ng-submit="submitForm()">
  Global Price: <input type="number" formControlName="globalPrice">
  <button type="button" [disabled]="mainForm.get('globalPrice').value === null" (click)="applyPriceToAll()">Apply to all</button>
  <table border formArrayName="orderLines">
  <ng-container *ngFor="let orderLine of orderLines let i=index" [formGroupName]="i">
    <tr>
       <td>{{orderLine.time | date}}</td>
       <td>{{orderLine.quantity}}</td>
       <td><input formControlName="price" type="number"></td>
    </tr>
</ng-container>
  </table>
</form>

Component

import { Component } from '@angular/core';
import { FormGroup, FormControl, FormArray } from '@angular/forms';

@Component({
  selector: 'my-app',
  templateUrl: './app.component.html',
  styleUrls: [ './app.component.css' ]
})
export class AppComponent  {
  name = 'Angular 6';
  mainForm: FormGroup;
  orderLines = [
    {price: 10, time: new Date(), quantity: 2},
    {price: 20, time: new Date(), quantity: 3},
    {price: 30, time: new Date(), quantity: 3},
    {price: 40, time: new Date(), quantity: 5}
    ]
  constructor() {
    this.mainForm = this.getForm();
  }

  getForm(): FormGroup {
    return new FormGroup({
      globalPrice: new FormControl(),
      orderLines: new FormArray(this.orderLines.map(this.getFormGroupForLine))
    })
  }

  getFormGroupForLine(orderLine: any): FormGroup {
    return new FormGroup({
      price: new FormControl(orderLine.price)
    })
  }

  applyPriceToAll() {
    const formLines = this.mainForm.get('orderLines') as FormArray;
    const globalPrice = this.mainForm.get('globalPrice').value;
    formLines.controls.forEach(control => control.get('price').setValue(globalPrice));
    // optionally recheck value and validity without emit event.
  }

  submitForm() {

  }
}

SELECT Id, 'TRUE' AS NewFiled FROM TABEL1
INTERSECT
SELECT Id, 'TRUE' AS NewFiled FROM TABEL2
UNION

Another native JS solution that can be useful for "complex" or deeply nested elements is to use NodeIterator. Put NodeFilter.SHOW_TEXT as the second argument ("whatToShow"), and iterate over just the text node children of the element.

var root = document.querySelector('p'),_x000D_
    iter = document.createNodeIterator(root, NodeFilter.SHOW_TEXT),_x000D_
    textnode;_x000D_
_x000D_
// print all text nodes_x000D_
while (textnode = iter.nextNode()) {_x000D_
  console.log(textnode.textContent)_x000D_
}

<p>_x000D_
<br>some text<br>123_x000D_
</p>

You can also use TreeWalker. The difference between the two is that NodeIterator is a simple linear iterator, while TreeWalker allows you to navigate via siblings and ancestors as well.

I have an application that I am developing that is laid out similar with Tabs in the Action Bar that launches fragments, some of these Fragments have multiple embedded Fragments within them.

I was getting the same error when I tried to run the application. It seems like if you instantiate the Fragments within the xml layout after a tab was unselected and then reselected I would get the inflator error.

I solved this replacing all the fragments in xml with Linearlayouts and then useing a Fragment manager/ fragment transaction to instantiate the fragments everything seems to working correctly at least on a test level right now.

I hope this helps you out.

I can think of a cheeky way to do it, I don't think this will be the best option but it will work.

Create the header as a separate table then place the other in a div and set a max size, then allow the scroll to come in by using overflow.

table {_x000D_
  width: 500px;_x000D_
}_x000D_
_x000D_
.scroll {_x000D_
  max-height: 60px;_x000D_
  overflow: auto;_x000D_
}

<table border="1">_x000D_
  <tr>_x000D_
  <th>head1</th>_x000D_
  <th>head2</th>_x000D_
  <th>head3</th>_x000D_
  <th>head4</th>_x000D_
  </tr>_x000D_
</table>_x000D_
<div class="scroll">_x000D_
  <table>_x000D_
    <tr><td>Text Text</td><td>Text Text</td><td>Text Text</td><td>Text Text</td></tr>_x000D_
    <tr><td>Text Text</td><td>Text Text</td><td>Text Text</td><td>Text Text</td></tr>_x000D_
    <tr><td>Text Text</td><td>Text Text</td><td>Text Text</td><td>Text Text</td></tr>_x000D_
    <tr><td>Text Text</td><td>Text Text</td><td>Text Text</td><td>Text Text</td></tr>_x000D_
    <tr><td>Text Text</td><td>Text Text</td><td>Text Text</td><td>Text Text</td></tr>_x000D_
    <tr><td>Text Text</td><td>Text Text</td><td>Text Text</td><td>Text Text</td></tr>_x000D_
    <tr><td>More Text</td><td>More Text</td><td>More Text</td><td>More Text</td></tr>_x000D_
    <tr><td>Text Text</td><td>Text Text</td><td>Text Text</td><td>Text Text</td></tr>_x000D_
    <tr><td>Even More Text Text</td><td>Even More Text Text</td><td>Even More Text Text</td><td>Even More Text Text</td></tr>_x000D_
  </table>_x000D_
</div>

There's now a much simpler solution than when this question was originally asked, five years ago. A CSS Flexbox makes the two column layout originally asked for easy. This is the bare bones equivalent of the table in the original question:

<div style="display: flex">
    <div>AAA</div>
    <div>BBB</div>
</div>

One of the nice things about a Flexbox is that it lets you easily specify how child elements should shrink and grow to adjust to the container size. I will expand on the above example to make the box the full width of the page, make the left column a minimum of 75px wide, and grow the right column to capture the leftover space. I will also pull the style into its own proper block, assign some background colors so that the columns are apparent, and add legacy Flex support for some older browsers.

<style type="text/css">
.flexbox {
    display: -ms-flex;
    display: -webkit-flex;
    display: flex;
    width: 100%;
}

.left {
    background: #a0ffa0;
    min-width: 75px;
    flex-grow: 0;
}

.right {
    background: #a0a0ff;
    flex-grow: 1;
}
</style>

...

<div class="flexbox">
    <div class="left">AAA</div>
    <div class="right">BBB</div>
</div>

Flex is relatively new, and so if you're stuck having to support IE 8 and IE 9 you can't use it. However, as of this writing, http://caniuse.com/#feat=flexbox indicates at least partial support by browsers used by 94.04% of the market.

It seems to be a bug in Swift. See discussion on Apple developers portal

It is said to be fixed in Xcode version that is about to be released. But for now there is temporary workaround:

Go to your target Build Settings and set Reflection Metadata Level flag to None

In your link.php your echo statement must be like this:

echo '<a href="pass.php?link=' . $a . '>Link 1</a>';
echo '<a href="pass.php?link=' . $b . '">Link 2</a>';

Then in your pass.php you cannot use $a because it was not initialized with your intended string value.

You can directly compare it to a string like this:

if($_GET['link'] == 'Link1')

Another way is to initialize the variable first to the same thing you did with link.php. And, a much better way is to include the $a and $b variables in a single PHP file, then include that in all pages where you are going to use those variables as Tim Cooper mention on his post. You can also include this in a session.

def tuple_insert(tup,pos,ele):
    tup = tup[:pos]+(ele,)+tup[pos:]
    return tup

tuple_insert(tup,pos,9999)

tup: tuple
pos: Position to insert
ele: Element to insert

I would use one repository per project. That way, the history becomes easier to browse through.

I would also check the version of the third party library I'm using, into the repository of the project using it.

This worked in my case:

sudo apt-get install libpq-dev

I used:

• Ubuntu 14.04.2 LTS
• Ruby 2.2.2
• Rails 4.2.1

You JSON is not a valid string as P. Galbraith has told you above.

and here is the solution for it.

<?php 
$json_url = "http://api.testmagazine.com/test.php?type=menu";
$json = file_get_contents($json_url);
$json=str_replace('},

]',"}

]",$json);
$data = json_decode($json);

echo "<pre>";
print_r($data);
echo "</pre>";
?>

Use this code it will work for you.

If you have a foreign key definition in some table and the name of the foreign key is used elsewhere as another foreign key you will have this error.

If the .c source files are converted .cpp (like as in parsec), then the extern needs to be followed by "C" as in

extern "C" void foo();

For the benefit of the community, since this thread is top on Google when searching for
"url validator java"

Catching exceptions is expensive, and should be avoided when possible. If you just want to verify your String is a valid URL, you can use the UrlValidator class from the Apache Commons Validator project.

For example:

String[] schemes = {"http","https"}; // DEFAULT schemes = "http", "https", "ftp"
UrlValidator urlValidator = new UrlValidator(schemes);
if (urlValidator.isValid("ftp://foo.bar.com/")) {
   System.out.println("URL is valid");
} else {
   System.out.println("URL is invalid");
}

@user755806 I do not believe that your question was answered. I took your code but used the 'foo' example string, added a lower function and also found the length of the hash returned. In sqlplus or Oracle's sql developer Java database client you can use this to call the md5sum of a value. The column formats clean up the presentation.

column hash_key format a34;
column hash_key_len format 999999;
select dbms_obfuscation_toolkit.md5(
          input => UTL_RAW.cast_to_raw('foo')) as hash_key,
       length(dbms_obfuscation_toolkit.md5(
          input => UTL_RAW.cast_to_raw('foo'))) as hash_key_len
 from dual;

The result set

HASH_KEY                           HASH_KEY_LEN
---------------------------------- ------------
acbd18db4cc2f85cedef654fccc4a4d8             32

is the same value that is returned from a Linux md5sum command.

echo -n foo | md5sum
acbd18db4cc2f85cedef654fccc4a4d8  -

1. Yes you can call or execute the sql statement directly in sqlplus or sql developer. I tested the sql statement in both clients against 11g.
2. You can use any C, C#, Java or other programming language that can send a statement to the database. It is the database on the other end of the call that needs to be able to understand the sql statement. In the case of 11 g, the code will work.
3. @tbone provides an excellent warning about the deprecation of the dbms_obfuscation_toolkit. However, that does not mean your code is unusable in 12c. It will work but you will want to eventually switch to dbms_crypto package. dbms_crypto is not available in my version of 11g.

TEXT is a data-type for text based input. On the other hand, you have BLOB and CLOB which are more suitable for data storage (images, etc) due to their larger capacity limits (4GB for example).

As for the difference between BLOB and CLOB, I believe CLOB has character encoding associated with it, which implies it can be suited well for very large amounts of text.

BLOB and CLOB data can take a long time to retrieve, relative to how quick data from a TEXT field can be retrieved. So, use only what you need.

Here's the updated FIDDLE

Your HTML should look like this (I only added the button):

<a class="fragment" href="google.com">
    <button id="closeButton">close</button>
    <div>
        <img src ="http://placehold.it/116x116" alt="some description"/> 
        <h3>the title will go here</h3>
        <h4> www.myurlwill.com </h4>
        <p class="text">
        this is a short description yada yada peanuts etc this is a short description yada yada peanuts etc this is a short description yada yada peanuts etc this is a short description yada yada peanuts etcthis is a short description yada yada peanuts etc 
        </p>
    </div>
</a>

and you should add the following CSS:

.fragment {
    position: relative;
}
#closeButton {
    position: absolute;
    top: 0;
    right: 0;
}

Then, to make the button actually work, you should add this javascript:

document.getElementById('closeButton').addEventListener('click', function(e) {
    e.preventDefault();
    this.parentNode.style.display = 'none';
}, false);

We're using e.preventDefault() here to prevent the anchor from following the link.

A set is an appropriate data structure for the output, since you presumably don't want redundancy in the output. A dictionary is ideal for looking up if a particular sequence of letters has been previously observed, and what word it originally came from. Taking advantage of the fact that we can add the same item to a set multiple times without expanding the set lets us get away with one for loop.

def return_anagrams(word_list):
    d = {}
    out = set()
    for word in word_list:
        s = ''.join(sorted(word))
        try:
            out.add(d[s])
            out.add(word)
        except:
            d[s] = word
    return out

A faster way of doing it takes advantage of the commutative property of addition:

import numpy as np

def vector_anagram(l):
    d, out = dict(), set()
    for word in l:
        s = np.zeros(26, dtype=int)
        for c in word:
            s[ord(c)-97] += 1
        s = tuple(s)
        try:
            out.add(d[s])
            out.add(word)
        except:
            d[s] = word
    return out

Those are all slightly different, and generally have an acceptable usage.

• var.ToString() is going to give you the string representation of an object, regardless of what type it is. Use this if var is not a string already.
• CStr(var) is the VB string cast operator. I'm not a VB guy, so I would suggest avoiding it, but it's not really going to hurt anything. I think it is basically the same as CType.
• CType(var, String) will convert the given type into a string, using any provided conversion operators.
• DirectCast(var, String) is used to up-cast an object into a string. If you know that an object variable is, in fact, a string, use this. This is the same as (string)var in C#.
• TryCast (as mentioned by @NotMyself) is like DirectCast, but it will return Nothing if the variable can't be converted into a string, rather than throwing an exception. This is the same as var as string in C#. The TryCast page on MSDN has a good comparison, too.

Could it be more useful for you to use the length of the list len(n) to inform your decision rather than checking n[i] for each possible length?

Try str.replace():

string = "it is icy"
print string.replace("i", "")

So, I've been reading a lot of the answers, and most of them don't take exceptions into account, like letters with accents or diaeresis (á, à, ä, etc.).

I made a function in typescript that should be pretty much extrapolable to any language that can use RegExp. This is my personal implementation for my use case in typescript. What I basically did is add ranges of letters with each kind of symbol that I wanted to add. I also converted the char to upper case before applying the RegExp, which saves me some work.

function isLetter(char: string): boolean {
  return char.toUpperCase().match('[A-ZÀ-ÚÄ-Ü\s]+') !== null;
}

If you want to add another range of letters with another kind of accent, just add it to the regex. Same goes for special symbols.

I implemented this function with TDD and I can confirm this works with, at least, the following cases:

    character | isLetter
    ${'A'}    | ${true}
    ${'e'}    | ${true}
    ${'Á'}    | ${true}
    ${'ü'}    | ${true}
    ${'ù'}    | ${true}
    ${'û'}    | ${true}
    ${'('}    | ${false}
    ${'^'}    | ${false}
    ${"'"}    | ${false}
    ${'`'}    | ${false}

Here's a nice function template using C++11 magic, working for both std::map, std::unordered_map:

template<template <typename...> class MAP, class KEY, class VALUE>
std::vector<KEY>
keys(const MAP<KEY, VALUE>& map)
{
    std::vector<KEY> result;
    result.reserve(map.size());
    for(const auto& it : map){
        result.emplace_back(it.first);
    }
    return result;
}

With oracle 10.2g:

select  level, sequence.NEXTVAL
from  dual 
connect by level <= (select max(pk) from tbl);

will set the current sequence value to the max(pk) of your table (i.e. the next call to NEXTVAL will give you the right result); if you use Toad, press F5 to run the statement, not F9, which pages the output (thus stopping the increment after, usually, 500 rows). Good side: this solution is only DML, not DDL. Only SQL and no PL-SQL. Bad side : this solution prints max(pk) rows of output, i.e. is usually slower than the ALTER SEQUENCE solution.

Strings can have for loops to:

for a in string:
    print a

If your arrays are not string arrays, use: memcpy(array2, array1, sizeof(array2));

See the docs FAQ: "How can I see the raw SQL queries Django is running?"

django.db.connection.queries contains a list of the SQL queries:

from django.db import connection
print(connection.queries)

Querysets also have a query attribute containing the query to be executed:

print(MyModel.objects.filter(name="my name").query)

Note that the output of the query is not valid SQL, because:

"Django never actually interpolates the parameters: it sends the query and the parameters separately to the database adapter, which performs the appropriate operations."

From Django bug report #17741.

Because of that, you should not send query output directly to a database.

you should use fmod(a,b)

While abs(x%y) < abs(y) is true mathematically, for floats it may not be true numerically due to roundoff.

For example, and assuming a platform on which a Python float is an IEEE 754 double-precision number, in order that -1e-100 % 1e100 have the same sign as 1e100, the computed result is -1e-100 + 1e100, which is numerically exactly equal to 1e100.

Function fmod() in the math module returns a result whose sign matches the sign of the first argument instead, and so returns -1e-100 in this case. Which approach is more appropriate depends on the application.

where x = a%b is used for integer modulo

To follow on from what others have said. I tend to have two layers:

The core layer. This is within a DLL that is added to nearly all web app projects. In this I have a SessionVars class which does the grunt work for Session state getters/setters. It contains code like the following:

public class SessionVar
{
    static HttpSessionState Session
    {
        get
        {
            if (HttpContext.Current == null)
                throw new ApplicationException("No Http Context, No Session to Get!");

            return HttpContext.Current.Session;
        }
    }

    public static T Get<T>(string key)
    {
        if (Session[key] == null)
            return default(T);
        else
            return (T)Session[key];
    }

    public static void Set<T>(string key, T value)
    {
        Session[key] = value;
    }
}

Note the generics for getting any type.

I then also add Getters/Setters for specific types, especially string since I often prefer to work with string.Empty rather than null for variables presented to Users.

e.g:

public static string GetString(string key)
{
    string s = Get<string>(key);
    return s == null ? string.Empty : s;
}

public static void SetString(string key, string value)
{
    Set<string>(key, value);
}

And so on...

I then create wrappers to abstract that away and bring it up to the application model. For example, if we have customer details:

public class CustomerInfo
{
    public string Name
    {
        get
        {
            return SessionVar.GetString("CustomerInfo_Name");
        }
        set
        {
            SessionVar.SetString("CustomerInfo_Name", value);
        }
    }
}

You get the idea right? :)

NOTE: Just had a thought when adding a comment to the accepted answer. Always ensure objects are serializable when storing them in Session when using a state server. It can be all too easy to try and save an object using the generics when on web farm and it go boom. I deploy on a web farm at work so added checks to my code in the core layer to see if the object is serializable, another benefit of encapsulating the Session Getters and Setters :)

It looks like the CSRF (Cross Site Request Forgery) protection in your Spring application is enabled. Actually it is enabled by default.

According to spring.io:

When should you use CSRF protection? Our recommendation is to use CSRF protection for any request that could be processed by a browser by normal users. If you are only creating a service that is used by non-browser clients, you will likely want to disable CSRF protection.

So to disable it:

@Configuration
public class RestSecurityConfig extends WebSecurityConfigurerAdapter {
  @Override
  protected void configure(HttpSecurity http) throws Exception {
    http.csrf().disable();
  }
}

If you want though to keep CSRF protection enabled then you have to include in your form the csrftoken. You can do it like this:

<form .... >
  ....other fields here....
  <input type="hidden"  name="${_csrf.parameterName}"   value="${_csrf.token}"/>
</form>

You can even include the CSRF token in the form's action:

<form action="./upload?${_csrf.parameterName}=${_csrf.token}" method="post" enctype="multipart/form-data">

You could search for the corresponding key or you could "invert" the dictionary, but considering how you use it, it would be best if you just iterated over key/value pairs in the first place, which you can do with items(). Then you have both directly in variables and don't need a lookup at all:

for key, value in PIX0.items():
    NUM = input("What is the Resolution of %s?"  % key)
    if NUM == value:

You can of course use that both ways then.

Or if you don't actually need the dictionary for something else, you could ditch the dictionary and have an ordinary list of pairs.

If you are interesting in modern api way, avoiding NSSearchPath and filter files in documents directory, before deletion, you can do like:

let fileManager = FileManager.default
let keys: [URLResourceKey] = [.nameKey, .isDirectoryKey]
let options: FileManager.DirectoryEnumerationOptions = [.skipsHiddenFiles, .skipsPackageDescendants]
guard let documentsUrl = fileManager.urls(for: .documentDirectory, in: .userDomainMask).last,
      let fileEnumerator = fileManager.enumerator(at: documentsUrl,
                                                  includingPropertiesForKeys: keys,
                                                  options: options) else { return }

let urls: [URL] = fileEnumerator.flatMap { $0 as? URL }
                                .filter { $0.pathExtension == "exe" }
for url in urls {
   do {
      try fileManager.removeItem(at: url)
   } catch {
      assertionFailure("\(error)")
   }
}
