The most simple way is to use find_element_by_class_name('class_name')

As of API 28 at least:

1. Open Settings app in emulator
2. Search for "Storage" select search result for it
3. Select Photos & Videos in Storage
4. Select Images
5. Drag an image onto the emulator, it won't immediately show up
6. From the AVD Manager in Android Studio, cold boot the emulator

The photos you've dragged in are now available.

try this one:

GIT_TRACE=1 git pull origin master

I encountered the same error, just add "--force" to the command, it works

git push origin master --force

You can add an IBAction to the uiTextField(the releation event is "Did End On Exit"),and the IBAction may named hideKeyboard,

-(IBAction)hideKeyboard:(id)sender
{
    [uitextfield resignFirstResponder];
}

also,you can apply it to the other textFields or buttons,for example,you may add a hidden button to the view,when you click it to hide the keyboard.

You can use Git GUI on Windows, see instructions:

1. Open the Git Gui (After installing the Git on your computer).

2. Clone your repository to your local hard drive:

3. After cloning, GUI opens, choose: "Rescan" for changes that you made:

4. You will notice the scanned files:

5. Click on "Stage Changed":

6. Approve and click "Commit":

7. Click on "Push":

8. Click on "Push":

9. Wait for the files to upload to git:

We have used SharpZipLib successfully on many projects. I know it's a third party tool, but source code is included and could provide some insight if you chose to reinvent the wheel here.

Packets and Frames are the names given to Protocol data units (PDUs) at different network layers

• Segments/Datagrams are units of data in the Transport Layer.

  In the case of the internet, the term Segment typically refers to TCP, while Datagram typically refers to UDP. However Datagram can also be used in a more general sense and refer to other layers (link):

  Datagram

  A self-contained, independent entity of data carrying sufficient information to be routed from the source to the destination computer without reliance on earlier exchanges between this source and destination computer andthe transporting network.

• Packets are units of data in the Network Layer (IP in case of the Internet)

• Frames are units of data in the Link Layer (e.g. Wifi, Bluetooth, Ethernet, etc).

This also works

SELECT *
FROM tableB
WHERE ID NOT IN (
  SELECT ID FROM tableA
);

For this example you really should just use an outer join.

declare
begin
  FOR attr_rec IN ( 
    select attr 
    from USER_TABLE u 
    left outer join attribute_table a 
    on ( u.USERTYPE = 'X' and a.user_id = u.id ) 
  ) LOOP
    <process records> 
    <if primary key of attribute_table is null 
     then the attribute does not exist for this user.>
  END LOOP;
END;

Rather than using a DisplayFilter you could use a very simple CaptureFilter like

port 53

See the "Capture only DNS (port 53) traffic" example on the CaptureFilters wiki.

The problem is your query returned false meaning there was an error in your query. After your query you could do the following:

if (!$result) {
    die(mysqli_error($link));
}

Or you could combine it with your query:

$results = mysqli_query($link, $query) or die(mysqli_error($link));

That will print out your error.

Also... you need to sanitize your input. You can't just take user input and put that into a query. Try this:

$query = "SELECT * FROM shopsy_db WHERE name LIKE '%" . mysqli_real_escape_string($link, $searchTerm) . "%'";

In reply to: Table 'sookehhh_shopsy_db.sookehhh_shopsy_db' doesn't exist

Are you sure the table name is sookehhh_shopsy_db? maybe it's really like users or something.

For Ubuntu 20.04 users with php-fpm I fixed the issue by adding the full path in the php conf:

edit /etc/php/7.4/fpm/conf.d/20-mysqli.ini

and replace

extension=mysqli.so

with:

extension=/usr/lib/php/20190902/mysqli.so

tldr:

docker image inspect myimage:mytag

By way of demonstration...

success, found image:

$ docker image pull busybox:latest
latest: Pulling from library/busybox

I'm facing the same issue here.

If this occurs right after you run brew install yarn try running yarn global add npm and voilà - fixed!

The first parameter to the iterator in forEach is the value and second is the key of the object.

angular.forEach(objectToIterate, function(value, key) {
    /* do something for all key: value pairs */
});

In your example, the outer forEach is actually:

angular.forEach($scope.filters, function(filterObj , filterKey)

Based on @Raghuram answer, I find a tutorial on Copying project dependencies, Just:

1. Open your project pom.xml file and find this:

   <project>
     [...]
     <build>
       <plugins>
         ...
       </plugins>
     </build>
     [...]
   </project>
   

2. Than replace the <plugins> ... </plugins> with:

   <plugins>
     <plugin>
       <groupId>org.apache.maven.plugins</groupId>
       <artifactId>maven-dependency-plugin</artifactId>
       <version>3.0.0</version>
       <executions>
         <execution>
           <id>copy-dependencies</id>
           <phase>package</phase>
           <goals>
             <goal>copy-dependencies</goal>
           </goals>
           <configuration>
             <outputDirectory>${project.build.directory}/alternateLocation</outputDirectory>
             <overWriteReleases>false</overWriteReleases>
             <overWriteSnapshots>false</overWriteSnapshots>
             <overWriteIfNewer>true</overWriteIfNewer>
           </configuration>
         </execution>
       </executions>
     </plugin>
   </plugins>
   

3. And call maven within the command line mvn dependency:copy-dependencies

After it finishes, it will create the folder target/dependency within all the jar's dependencies on the current directory where the pom.xml lives.

You can use like this...

<div id="rot">hello</div>

#rot
{
   -webkit-transform: rotate(-90deg); 
   -moz-transform: rotate(-90deg);    
    width:100px;
}

Have a look at this fiddle:http://jsfiddle.net/anish/MAN4g/

Imam Mahdi aj

You can use the properties section

You may also have to use it in onPause or onDestroy of Activity Life Cycle:

//you may call the cancel() method but if it is not handled in doInBackground() method
if (loginTask != null && loginTask.getStatus() != AsyncTask.Status.FINISHED)
    loginTask.cancel(true);

where loginTask is object of your AsyncTask

Thank you.

To understand why it is necessary to distinguish between int and long literals, consider:

long l = -1 >>> 1;

versus

int a = -1;
long l = a >>> 1;

Now as you would rightly expect, both code fragments give the same value to variable l. Without being able to distinguish int and long literals, what is the interpretation of -1 >>> 1?

-1L >>> 1 // ?

or

(int)-1 >>> 1 // ?

So even if the number is in the common range, we need to specify type. If the default changed with magnitude of the literal, then there would be a weird change in the interpretations of expressions just from changing the digits.

This does not occur for byte, short and char because they are always promoted before performing arithmetic and bitwise operations. Arguably their should be integer type suffixes for use in, say, array initialisation expressions, but there isn't. float uses suffix f and double d. Other literals have unambiguous types, with there being a special type for null.

Assuming your row number is in B1, you can use INDIRECT:

=INDIRECT("A" & B1)

This takes a cell reference as a string (in this case, the concatenation of A and the value of B1 - 5), and returns the value at that cell.

This is the proper way to do it:

INSERT INTO destinationTable
SELECT * FROM sourceTable

Just send xml bytes directly:

#!/usr/bin/env python2
# -*- coding: utf-8 -*-
import requests

xml = """<?xml version='1.0' encoding='utf-8'?>
<a>?</a>"""
headers = {'Content-Type': 'application/xml'} # set what your server accepts
print requests.post('http://httpbin.org/post', data=xml, headers=headers).text

Output

{
  "origin": "x.x.x.x",
  "files": {},
  "form": {},
  "url": "http://httpbin.org/post",
  "args": {},
  "headers": {
    "Content-Length": "48",
    "Accept-Encoding": "identity, deflate, compress, gzip",
    "Connection": "keep-alive",
    "Accept": "*/*",
    "User-Agent": "python-requests/0.13.9 CPython/2.7.3 Linux/3.2.0-30-generic",
    "Host": "httpbin.org",
    "Content-Type": "application/xml"
  },
  "json": null,
  "data": "<?xml version='1.0' encoding='utf-8'?>\n<a>\u0431</a>"
}

It really really does make the flow of a sequence with several lookups and optionals much more concise and clear and reduces lots of if nesting. See Erica Sadun post on replacing Ifs. .... Could get carried away, an example below:

    let filteredLinks = locationsLinkedToList.filter({$0.actionVerb == movementCommand})
    guard let foundLink = filteredLinks.first else {return ("<Person> cannot go in that direction.", nil, nil)}
    guard filteredLinks.count == 1 else {return ("<Person> cannot decide which route to take.", nil, nil)}
    guard let nextLocation = foundLink.toLocation else {return ("<Person> cannot go in that direction.", nil, nil)}

See if that sticks.

After update to macOS 10.13.3

After updating do macOS 10.13, I had to install "Command Line Tools (macOS 10.13) for Xcode 9.3" downloaded from https://developer.apple.com/download/more/

This worked for me:

comboBox1.DataSource = Enum.GetValues(typeof(MyEnum));
comboBox1.SelectedIndex = comboBox1.FindStringExact(MyEnum.something.ToString());

You want to specify a custom tooltip template in your chart options, like this :

 // String - Template string for single tooltips
 tooltipTemplate: "<%if (label){%><%=label %>: <%}%><%= value + ' %' %>",
 // String - Template string for multiple tooltips
 multiTooltipTemplate: "<%= value + ' %' %>",

This way you can add a '%' sign after your values if that's what you want.

Here's a jsfiddle to illustrate this.

Note that tooltipTemplate applies if you only have one dataset, multiTooltipTemplate applies if you have several datasets.

This options are mentioned in the global chart configuration section of the documentation. Do have a look, it's worth checking for all the other options that can be customized in there.

Note that Your datasets should only contain numeric values. (No % signs or other stuff there).

[System.Diagnostics.FileVersionInfo]::GetVersionInfo("Path\To\File.dll")

doc.id gets the UID.

Combine with the rest of the data for one object like so:

Object.assign({ uid: doc.id }, doc.data())

You can access rails app path using variable RAILS_ROOT.

For example:

render :file => "#{RAILS_ROOT}/public/layouts/mylayout.html.erb"

use & in place of &

change to

<string name="magazine">Newspaper &amp; Magazines</string>

To make understanding better , lets find out where exactly bind and connect comes into picture,

Further to positioning of two calls , as clarified by Sourav,

bind() associates the socket with its local address [that's why server side binds, so that clients can use that address to connect to server.] connect() is used to connect to a remote [server] address, that's why is client side, connect [read as: connect to server] is used.

We cannot use them interchangeably (even when we have client/server on same machine) because of specific roles and corresponding implementation.

I will further recommend to correlate these calls TCP/IP handshake .

So , who will send SYN here , it will be connect() . While bind() is used for defining the communication end point.

Hope this helps!!

There are two ways to run tomcat in debug mode

1. Using jdpa run

2. Using JAVA_OPTS

First setup the environment. Then start the server using following commands.

export JPDA_ADDRESS=8000_x000D_
_x000D_
export JPDA_TRANSPORT=dt_socket_x000D_
_x000D_
%TOMCAT_HOME%/bin/catalina.sh jpda start_x000D_
_x000D_
sudo catalina.sh jpda start

refer this article for more information this is clearly define it

For whatever reason, the top answer by wchargin was giving me a null pointer error when I was calling this.getClass().getResourceAsStream().

What worked for me was the following:

void playSound(String soundFile) {
    File f = new File("./" + soundFile);
    AudioInputStream audioIn = AudioSystem.getAudioInputStream(f.toURI().toURL());  
    Clip clip = AudioSystem.getClip();
    clip.open(audioIn);
    clip.start();
}

And I would play the sound with:

 playSound("sounds/effects/sheep1.wav");

sounds/effects/sheep1.wav was located in the base directory of my project in Eclipse (so not inside the src folder).

Say you were provided the following:

<x:Envelope xmlns:x="http://schemas.xmlsoap.org/soap/envelope/" xmlns:int="http://thesite.com/">
    <x:Header/>
    <x:Body>
        <int:authenticateLogin>
            <int:LoginId>12345</int:LoginId>
        </int:authenticateLogin>
    </x:Body>
</x:Envelope>

and

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
    <s:Body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
        <authenticateLoginResponse xmlns="http://thesite.com/">
            <authenticateLoginResult>
                <RequestStatus>true</RequestStatus>
                <UserName>003p0000006XKX3AAO</UserName>
                <BearerToken>Abcdef1234567890</BearerToken>
            </authenticateLoginResult>
        </authenticateLoginResponse>
    </s:Body>
</s:Envelope>

Let's say that accessing http://thesite.com/ said that the WSDL address is: http://thesite.com/PortalIntegratorService.svc?wsdl

$client = new SoapClient('http://thesite.com/PortalIntegratorService.svc?wsdl');
$result = $client->authenticateLogin(array('LoginId' => 12345));
if (!empty($result->authenticateLoginResult->RequestStatus)
    && !empty($result->authenticateLoginResult->UserName)) {
    echo 'The username is: '.$result->authenticateLoginResult->UserName;
}

As you can see, the items specified in the XML are used in the PHP code though the LoginId value can be changed.

You don't need to change the compliance level here, or rather, you should but that's not the issue.

The code compliance ensures your code is compatible with a given Java version.

For instance, if you have a code compliance targeting Java 6, you can't use Java 7's or 8's new syntax features (e.g. the diamond, the lambdas, etc. etc.).

The actual issue here is that you are trying to compile something in a Java version that seems different from the project dependencies in the classpath.

Instead, you should check the JDK/JRE you're using to build.

In Eclipse, open the project properties and check the selected JRE in the Java build path.

If you're using custom Ant (etc.) scripts, you also want to take a look there, in case the above is not sufficient per se.

As Heinzi said, an array has a fixed size. In order to 'remove an item' or 'resize' it, you'll have to create a new array with the desired size and copy the items you need as appropriate.

Here's code to remove an item from an array:

<System.Runtime.CompilerServices.Extension()> _
Function RemoveAt(Of T)(ByVal arr As T(), ByVal index As Integer) As T()
    Dim uBound = arr.GetUpperBound(0)
    Dim lBound = arr.GetLowerBound(0)
    Dim arrLen = uBound - lBound

    If index < lBound OrElse index > uBound Then
        Throw New ArgumentOutOfRangeException( _
        String.Format("Index must be from {0} to {1}.", lBound, uBound))

    Else
        'create an array 1 element less than the input array
        Dim outArr(arrLen - 1) As T
        'copy the first part of the input array
        Array.Copy(arr, 0, outArr, 0, index)
        'then copy the second part of the input array
        Array.Copy(arr, index + 1, outArr, index, uBound - index)

        Return outArr
    End If
End Function

You can use it as such:

Module Module1

    Sub Main()
        Dim arr = New String() {"abc", "mno", "xyz"}
        arr.RemoveAt(1)
    End Sub
End Module

The code above removes the second element ("mno") [which has an index of 1] from the array.

You need to be developing in .NET 3.5 or higher in order to use the extension method. If you're using .NET 2.0 or 3.0, you can call the method as such

arr = RemoveAt(arr, 1)

I hope this is what you need.

Update

After running tests based on ToolMakerSteve's comment it appears the initial code does not modify the array you want to update because of the ByVal used in the function's declaration. However, writing code like arr = arr.RemoveAt(1) or arr = RemoveAt(arr, 1) does modify the array because it reassigns the modified array to the original.

Find below the updated method (subroutine) for removing an element from an array.

<System.Runtime.CompilerServices.Extension()> _
Public Sub RemoveAt(Of T)(ByRef arr As T(), ByVal index As Integer)
    Dim uBound = arr.GetUpperBound(0)
    Dim lBound = arr.GetLowerBound(0)
    Dim arrLen = uBound - lBound

    If index < lBound OrElse index > uBound Then
        Throw New ArgumentOutOfRangeException( _
        String.Format("Index must be from {0} to {1}.", lBound, uBound))

    Else
        'create an array 1 element less than the input array
        Dim outArr(arrLen - 1) As T
        'copy the first part of the input array
        Array.Copy(arr, 0, outArr, 0, index)
        'then copy the second part of the input array
        Array.Copy(arr, index + 1, outArr, index, uBound - index)

        arr = outArr
    End If
End Sub

Usage of the method is similar to the original, except there is no return value this time so trying to assign an array from the return value will not work because nothing is returned.

Dim arr = New String() {"abc", "mno", "xyz"}
arr.RemoveAt(1)  ' Output: {"abc", "mno"} (works on .NET 3.5 and higher)
RemoveAt(arr, 1) ' Output: {"abc", "mno"} (works on all versions of .NET fx)
arr = arr.RemoveAt(1)  'will not work; no return value
arr = RemoveAt(arr, 1) 'will not work; no return value

Note:

1. I use a temporary array for the process because it makes my intentions clear and that is exactly what VB.NET does behind the scenes when you do Redim Preserve. If you would like to modify the array in-place using Redim Preserve, see ToolmakerSteve's answer.

2. The RemoveAt methods written here are extension methods. In order for them to work, you will have to paste them in a Module. Extension methods will not work in VB.NET if they are placed in a Class.

3. Important If you will be modifying your array with lots of 'removes', it is highly recommended to use a different data structure such as List(Of T) as suggested by other answerers to this question.

For i = 0 To dt.Rows.Count - 1

    ListV.Items.Add(dt.Rows(i).Item("STU_NUMBER").ToString)
    ListV.Items(i).SubItems.Add(dt.Rows(i).Item("FNAME").ToString & " " & dt.Rows(i).Item("MI").ToString & ". " & dt.Rows(i).Item("LNAME").ToString)
    ListV.Items(i).SubItems.Add(dt.Rows(i).Item("SEX").ToString)

Next

Try using entity codes such as 
 for CR, 
 for LF, and 	 for TAB.

For example:

<div title="1)&#009;A&#013;&#010;2)&#009;B">Hover Me</div>

 <Grid >
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="*"/>
    </Grid.ColumnDefinitions>
    <Button Command="{Binding ClickCommand}" Width="100" Height="100" Content="wefwfwef"/>
</Grid>

the code behind for the window:

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
        DataContext = new ViewModelBase();
    }
}

The ViewModel:

public class ViewModelBase
{
    private ICommand _clickCommand;
    public ICommand ClickCommand
    {
        get
        {
            return _clickCommand ?? (_clickCommand = new CommandHandler(() => MyAction(), ()=> CanExecute));
        }
    }
     public bool CanExecute
     {
        get
        {
            // check if executing is allowed, i.e., validate, check if a process is running, etc. 
            return true/false;
        }
     }

    public void MyAction()
    {

    }
}

Command Handler:

 public class CommandHandler : ICommand
{
    private Action _action;
    private Func<bool> _canExecute;

    /// <summary>
    /// Creates instance of the command handler
    /// </summary>
    /// <param name="action">Action to be executed by the command</param>
    /// <param name="canExecute">A bolean property to containing current permissions to execute the command</param>
    public CommandHandler(Action action, Func<bool> canExecute)
    {
        _action = action;
        _canExecute = canExecute;
    }

    /// <summary>
    /// Wires CanExecuteChanged event 
    /// </summary>
    public event EventHandler CanExecuteChanged
    {
        add { CommandManager.RequerySuggested += value; }
        remove { CommandManager.RequerySuggested -= value; }
    }

    /// <summary>
    /// Forcess checking if execute is allowed
    /// </summary>
    /// <param name="parameter"></param>
    /// <returns></returns>
    public bool CanExecute(object parameter)
    {
        return _canExecute.Invoke();
    }

    public void Execute(object parameter)
    {
        _action();
    }
}

I hope this will give you the idea.

in linux/ubuntu you can do, run following commands

Use the absolute value function ABS. The syntax is

ABS ( numeric_expression )

Most of the answers for this question use the the Canvas drawing method or drawing cache method. However, the View.setDrawingCache() method is deprecated in API 28. Currently the recommended API for making screenshots is the PixelCopy class available from API 24 (but the methods which accept Window parameter are available from API 26 == Android 8.0 Oreo). Here is a sample Kotlin code for retrieving a Bitmap:

@RequiresApi(Build.VERSION_CODES.O)
fun saveScreenshot(view: View) {
    val window = (view.context as Activity).window
    if (window != null) {
        val bitmap = Bitmap.createBitmap(view.width, view.height, Bitmap.Config.ARGB_8888)
        val locationOfViewInWindow = IntArray(2)
        view.getLocationInWindow(locationOfViewInWindow)
        try {
            PixelCopy.request(window, Rect(locationOfViewInWindow[0], locationOfViewInWindow[1], locationOfViewInWindow[0] + view.width, locationOfViewInWindow[1] + view.height), bitmap, { copyResult ->
                if (copyResult == PixelCopy.SUCCESS) {
                    saveBitmap(bitmap)
                }
                // possible to handle other result codes ...
            }, Handler())
        } catch (e: IllegalArgumentException) {
            // PixelCopy may throw IllegalArgumentException, make sure to handle it
        }
    }
}

Using fs package we can create excel/CSV file from JSON data.

Step 1: Store JSON data in a variable (here it is in jsn variable).

Step 2: Create empty string variable(here it is data).

Step 3: Append every property of jsn to string variable data, while appending put '\t' in-between 2 cells and '\n' after completing the row.

Code:

var fs = require('fs');

var jsn = [{
    "name": "Nilesh",
    "school": "RDTC",
    "marks": "77"
   },{
    "name": "Sagar",
    "school": "RC",
    "marks": "99.99"
   },{
    "name": "Prashant",
    "school": "Solapur",
    "marks": "100"
 }];

You don't need anything special for adding paramaters. Just like you had it.

Route::get('groups/(:any)', array('as' => 'group', 'uses' => 'groups@show'));


class Groups_Controller extends Base_Controller {

    public $restful = true;    

    public function get_show($groupID) {
        return 'I am group id ' . $groupID;
    }  


}

As a DBA, You must schedule the backup of MySQL Database in case of any issues so that you can recover your databases from the current backup.

Here, we are using mysqldump to take the backup of mysql databases and the same you can put into the script.

[orahow@oradbdb DB_Backup]$ cat .backup_script.sh

#!/bin/bash
# Database credentials
user="root"
password="1Loginxx"
db_name="orahowdb"
v_cnt=0
logfile_path=/DB_Backup
touch "$logfile_path/orahowdb_backup.log"
# Other options
backup_path="/DB_Backup"
date=$(date +"%d-%b-%Y-%H-%M-%p")
# Set default file permissions

Continue Reading .... MySQL Backup

If you don't have permissions to change your default DB you could manually select a different DB at the top of your queries...

USE [SomeOtherDb]
SELECT 'I am now using a different DB'

Will work as long as you have permission to the other DB

First of all I'd like to say that I 100% agree with John Saunders that you must avoid loops in SQL in most cases especially in production.

But occasionally as a one time thing to populate a table with a hundred records for testing purposes IMHO it's just OK to indulge yourself to use a loop.

For example in your case to populate your table with records with hospital ids between 16 and 100 and make emails and descriptions distinct you could've used

CREATE PROCEDURE populateHospitals
AS
DECLARE @hid INT;
SET @hid=16;
WHILE @hid < 100
BEGIN 
    INSERT hospitals ([Hospital ID], Email, Description) 
    VALUES(@hid, 'user' + LTRIM(STR(@hid)) + '@mail.com', 'Sample Description' + LTRIM(STR(@hid))); 
    SET @hid = @hid + 1;
END

And result would be

ID   Hospital ID Email            Description          
---- ----------- ---------------- ---------------------
1    16          [email protected]  Sample Description16 
2    17          [email protected]  Sample Description17 
...                                                    
84   99          [email protected]  Sample Description99 

I had something similar, and here's (an edited) version of what I ended up using successfully:

ISNULL(CONVERT(VARCHAR(50),[column name goes here],[date style goes here] ),'')

Here's why this works: If you select a date which is NULL, it will show return NULL, though it is really stored as 01/01/1900. This is why an ISNULL on the date field, while you're working with any date data type will not treat this as a NULL, as it is technically not being stored as a NULL.

However, once you convert it to a new datatype, it will convert it as a NULL, and at that point, you're ISNULL will work as you expect it to work.

I hope this works out for you as well!

~Eli

Update, nearly one year later:

I had a similar situation, where I needed the output to be of the date data-type, and my aforementioned solution didn't work (it only works if you need it displayed as a date, not be of the date data type.

If you need it to be of the date data-type, there is a way around it, and this is to nest a REPLACE within an ISNULL, the following worked for me:

Select 
    ISNULL(
        REPLACE(
            [DATE COLUMN NAME],
            '1900-01-01',
            ''
        ),
    '') AS [MeaningfulAlias]

Try -o "ProxyCommand=nc --proxy HOST:PORT %h %p" for command in question. It worked on OEL6 but need to modify as mentioned for OEL7.

JavaScript is a client-side language and your MySQL database is going to be running on a server.

So you have to rename your file to index.php for example (.php is important) so you can use php code for that. It is not very difficult, but not directly possible with html.

(Somehow you can tell your server to let the html files behave like php files, but this is not the best solution.)

So after you renamed your file, go to the very top, before <html> or <!DOCTYPE html> and type:

<?php
    if($_SERVER['REQUEST_METHOD'] == 'POST') {
        /*Creating variables*/
        $name = $_POST["name"];
        $address = $_POST["address"];
        $age = $_POST["age"];


        $dbhost = "localhost"; /*most of the time it's localhost*/
        $username = "yourusername";
        $password = "yourpassword";
        $dbname = "mydatabase";

        $mysql = mysqli_connect($dbhost, $username, $password, $dbname); //It connects
        $query = "INSERT INTO yourtable (name,address,age) VALUES $name, $address, $age";
        mysqli_query($mysql, $query);
    }
?>
<!DOCTYPE html>
<html>
<head>.......
....
    <form method="post">
        <input name="name" type="text"/>
        <input name="address" type="text"/>
        <input name="age" type="text"/>
    </form>
....

You can use the Set-Variable cmdlet. Passing $global:var3 sends the value of $var3, which is not what you want. You want to send the name.

$global:var1 = $null

function foo ($a, $b, $varName)
{
   Set-Variable -Name $varName -Value ($a + $b) -Scope Global
}

foo 1 2 var1

This is not very good programming practice, though. Below would be much more straightforward, and less likely to introduce bugs later:

$global:var1 = $null

function ComputeNewValue ($a, $b)
{
   $a + $b
}

$global:var1 = ComputeNewValue 1 2

It's preferable to use context managers to close the files automatically

with open("new.txt", "r"), open('xyz.txt', 'w') as textfile, myfile:
    for line in textfile:
        var1, var2 = line.split(",");
        myfile.writelines(var1)

I would say Ruby is slow because not much effort has been spent in making the interpreter faster. Same applies to Python. Smalltalk is just as dynamic as Ruby or Python but performs better by a magnitude, see http://benchmarksgame.alioth.debian.org. Since Smalltalk was more or less replaced by Java and C# (that is at least 10 years ago) no more performance optimization work had been done for it and Smalltalk is still ways faster than Ruby and Python. The people at Xerox Parc and at OTI/IBM had the money to pay the people that work on making Smalltalk faster. What I don't understand is why Google doesn't spend the money for making Python faster as they are a big Python shop. Instead they spend money on development of languages like Go...

If you're doing this in an Node.js app, you can use the leap-year package:

npm install --save leap-year

Then from your app, use the following code to verify whether the provided year or date object is a leap year:

var leapYear = require('leap-year');

leapYear(2014);
//=> false 

leapYear(2016);
//=> true 

Using a library like this has the advantage that you don't have to deal with the dirty details of getting all of the special cases right, since the library takes care of that.

One thing to watch out for in benchmarks (especially phpbench.com), is even though the numbers are sound, the tests are not. Alot of the tests on phpbench.com are doing things at are trivial and abuse PHP's ability to cache array lookups to skew benchmarks or in the case of iterating over an array doesn't actually test it in real world cases (no one writes empty for loops). I've done my own benchmarks that I've found are fairly reflective of the real world results and they always show the language's native iterating syntax foreach coming out on top (surprise, surprise).

//make a nicely random array
$aHash1 = range( 0, 999999 );
$aHash2 = range( 0, 999999 );
shuffle( $aHash1 );
shuffle( $aHash2 );
$aHash = array_combine( $aHash1, $aHash2 );


$start1 = microtime(true);
foreach($aHash as $key=>$val) $aHash[$key]++;
$end1 = microtime(true);

$start2 = microtime(true);
while(list($key) = each($aHash)) $aHash[$key]++;
$end2 = microtime(true);


$start3 = microtime(true);
$key = array_keys($aHash);
$size = sizeOf($key);
for ($i=0; $i<$size; $i++) $aHash[$key[$i]]++;
$end3 = microtime(true);

$start4 = microtime(true);
foreach($aHash as &$val) $val++;
$end4 = microtime(true);

echo "foreach ".($end1 - $start1)."\n"; //foreach 0.947947025299
echo "while ".($end2 - $start2)."\n"; //while 0.847212076187
echo "for ".($end3 - $start3)."\n"; //for 0.439476966858
echo "foreach ref ".($end4 - $start4)."\n"; //foreach ref 0.0886030197144

//For these tests we MUST do an array lookup,
//since that is normally the *point* of iteration
//i'm also calling noop on it so that PHP doesn't
//optimize out the loopup.
function noop( $value ) {}

//Create an array of increasing indexes, w/ random values
$bHash = range( 0, 999999 );
shuffle( $bHash );

$bstart1 = microtime(true);
for($i = 0; $i < 1000000; ++$i) noop( $bHash[$i] );
$bend1 = microtime(true);

$bstart2 = microtime(true);
$i = 0; while($i < 1000000) { noop( $bHash[$i] ); ++$i; }
$bend2 = microtime(true);


$bstart3 = microtime(true);
foreach( $bHash as $value ) { noop( $value ); }
$bend3 = microtime(true);

echo "for ".($bend1 - $bstart1)."\n"; //for 0.397135972977
echo "while ".($bend2 - $bstart2)."\n"; //while 0.364789962769
echo "foreach ".($bend3 - $bstart3)."\n"; //foreach 0.346374034882

@Frode F. gave the right answer.

By the Way Invoke-WebRequest also prints you the 200 OK and a lot of bla, bla, bla... which might be useful but I still prefer the Invoke-RestMethod which is lighter.

Also, keep in mind that you need to use | ConvertTo-Json for the body only, not the header:

$body = @{
 "UserSessionId"="12345678"
 "OptionalEmail"="[email protected]"
} | ConvertTo-Json

$header = @{
 "Accept"="application/json"
 "connectapitoken"="97fe6ab5b1a640909551e36a071ce9ed"
 "Content-Type"="application/json"
} 

Invoke-RestMethod -Uri "http://MyServer/WSVistaWebClient/RESTService.svc/member/search" -Method 'Post' -Body $body -Headers $header | ConvertTo-HTML

and you can then append a | ConvertTo-HTML at the end of the request for better readability

An Instant is what it says: a specific instant in time - it does not have the notion of date and time (the time in New York and Tokyo is not the same at a given instant).

To print it as a date/time, you first need to decide which timezone to use. For example:

System.out.println(LocalDateTime.ofInstant(i, ZoneOffset.UTC));

This will print the date/time in iso format: 2015-06-02T10:15:02.325

If you want a different format you can use a formatter:

LocalDateTime datetime = LocalDateTime.ofInstant(i, ZoneOffset.UTC);
String formatted = DateTimeFormatter.ofPattern("yyyy-MM-dd hh:mm:ss").format(datetime);
System.out.println(formatted);

It is also possible to get this error if the foreign key is not a primary key within its own table.

I did an ALTER TABLE and accidentally removed the primary key status of a column, and got this error.

An additional reason could be that you're pointing to a workspace on a drive that no longer exists, thinking that you're choosing the valid one. For instance, for me the workspace used to exist on the F drive, but now it is on my D drive. Even though I don't have the F drive anymore it is still listed as a workspace I once used during Eclipse startup. When I choose this old workspace Eclipse complains that the workspace is "in use", which is very strange.

In PostgreSQL, another possibility is to use the first_value window function in combination with SELECT DISTINCT:

select distinct customer_id,
                first_value(row(id, total)) over(partition by customer_id order by total desc, id)
from            purchases;

I created a composite (id, total), so both values are returned by the same aggregate. You can of course always apply first_value() twice.

I know an answer has already been provided, but dselect didn't work for me. Here is what worked to find the packages to remove:

# search postgr  | grep ^i
i   postgresql                      - object-relational SQL database (supported

I know this is an old thread but to further expand the answer here, by default IIS 7.5 creates application pool identity accounts to run the worker process under. You can't search for these accounts like normal user accounts when adding file permissions. To add them into NTFS permission ACL you can type the entire name of the application pool identity and it will work.

It is just a slight difference in the way the application pool identity accounts are handle as they are seen to be virtual accounts.

Also the username of the application pool identity is "IIS AppPool\application pool name" so if it was the application pool DefaultAppPool the user account would be "IIS AppPool\DefaultAppPool".

These can be seen if you open computer management and look at the members of the local group IIS_IUSRS. The SID appended to the end of them is not need when adding the account into an NTFS permission ACL.

Hope that helps

This is for shorthand syntax

=placeholder
  &::-webkit-input-placeholder
    @content
  &:-moz-placeholder
    @content
  &::-moz-placeholder
    @content
  &:-ms-input-placeholder
    @content

use it like

input
  +placeholder
    color: red

It doesn't matter if the executable has arguments or not. To run GDB on any binary with a generated core file, the syntax is below.

Syntax:
gdb <binary name> <generated core file>
Eg:
gdb l3_entity 6290-corefile

Let me take the below example for more understanding.

bash-4.1$ **gdb l3_entity 6290-corefile**

**Core was generated** by `/dir1/dir2/dir3/l3_entity **Program terminated with signal SIGABRT, Aborted.**
#0
#1
#2
#3
#4
#5
#6
#7
#8
#9
#10
(gdb)

From the above output, you can guess something about core, whether it is a NULL access, SIGABORT, etc..

These numbers #0 to #10 are the stack frames of GDB. These stack frames are not of your binary. In the above 0 - 10 frames if you suspect anything wrong select that frame

(gdb) frame 8

Now to see more details about it:

(gdb) list +

To investigate the issue further, you can print the suspected variable values here at this point in time.

(gdb) print thread_name

To help you with your problem I found this blog which talks about making laravel production optimized. Most of what you need to do to make your app fast would now be in the hands of how efficient your code is, your network capacity, CDN, caching, database.

Now I will talk about the issue:

Laravel is slow out of the box. There are ways to optimize it. You also have the option of using caching in your code, improving your server machine, yadda yadda yadda. But in the end Laravel is still slow.

Laravel uses a lot of symfony libraries and as you can see in techempower's benchmarks, symfony ranks very low (last to say the least). You can even find the laravel benchmark to be almost at the bottom.

A lot of auto-loading is happening in the background, things you might not even need gets loaded. So technically because laravel is easy to use, it helps you build apps fast, it also makes it slow.

But I am not saying Laravel is bad, it is great, great at a lot of things. But if you expect a high surge of traffic you will need a lot more hardware just to handle the requests. It would cost you a lot more. But if you are filthy rich then you can achieve anything with Laravel. :D

The usual trade-off:

 Easy = Slow, Hard = Fast

I would consider C or Java to have a hard learning curve and a hard maintainability but it ranks very high in web frameworks.

Though not too related. I'm just trying to prove the point of easy = slow:

Ruby has a very good reputation in maintainability and the easiness to learn it but it is also considered to be the slowest among python and php as shown here.

var givenStartDate = $('#startDate').val();
        alert('START DATE'+givenStartDate);
        var givenEndDate = $('#endDate').val();
        alert('END DATE'+givenEndDate);
        var date = new Date();
        var month = date.getMonth()+1;
        var day = date.getDate();
        var currentDate = date.getFullYear() + '-' +
            (month<10 ? '0' : '') + month + '-' +
            (day<10 ? '0' : '') + day;
        if(givenStartDate < currentDate || givenEndDate < currentDate)
         { 
        $("#updateButton").attr("disabled","disabled"); 
         }
         if(givenStartDate < currentDate && givenEndDate > currentDate)
            {
            $("#updateButton").attr("enabled","enabled");
            }
         if(givenStartDate > currentDate || givenEndDate > currentDate) { 
        $("#updateButton").attr("enabled","enabled"); 
         }

Try this. If any mistake, please correct me :) Thanks all.

getClass().getResource() uses the class loader to load the resource. This means that the resource must be in the classpath to be loaded.

When doing it with Eclipse, everything you put in the source folder is "compiled" by Eclipse:

• .java files are compiled into .class files that go the the bin directory (by default)
• other files are copied to the bin directory (respecting the package/folder hirearchy)

When launching the program with Eclipse, the bin directory is thus in the classpath, and since it contains the Test.properties file, this file can be loaded by the class loader, using getResource() or getResourceAsStream().

If it doesn't work from the command line, it's thus because the file is not in the classpath.

Note that you should NOT do

FileInputStream inputStream = new FileInputStream(new File(getClass().getResource(url).toURI()));

to load a resource. Because that can work only if the file is loaded from the file system. If you package your app into a jar file, or if you load the classes over a network, it won't work. To get an InputStream, just use

getClass().getResourceAsStream("Test.properties")

And finally, as the documentation indicates,

Foo.class.getResourceAsStream("Test.properties")

will load a Test.properties file located in the same package as the class Foo.

Foo.class.getResourceAsStream("/com/foo/bar/Test.properties")

will load a Test.properties file located in the package com.foo.bar.

It's the directory where java was run from, where you started the JVM. Does not have to be within the user's home directory. It can be anywhere where the user has permission to run java.

So if you cd into /somedir, then run your program, user.dir will be /somedir.

A different property, user.home, refers to the user directory. As in /Users/myuser or /home/myuser or C:\Users\myuser.

See here for a list of system properties and their descriptions.

You can set UIButton title color with hex code

btn.setTitleColor(UIColor(hexString: "#95469F"), for: .normal)

Presumably, those columns are integer columns - which will be the reason as the result of the calculation will be of the same type.

e.g. if you do this:

SELECT 1 / 2

you will get 0, which is obviously not the real answer. So, convert the values to e.g. decimal and do the calculation based on that datatype instead.

e.g.

SELECT CAST(1 AS DECIMAL) / 2

gives 0.500000

To access any element of a list in a YAML file like this:

global:
  registry:
    url: dtr-:5000/
    repoPath:
  dbConnectionString: jdbc:oracle:thin:@x.x.x.x:1521:abcd

You can use following python script:

import yaml

with open("/some/path/to/yaml.file", 'r') as f:
    valuesYaml = yaml.load(f, Loader=yaml.FullLoader)

print(valuesYaml['global']['dbConnectionString'])

I had to use COUNTIF() in my case as part of my SELECT columns AND to mimic a % of the number of times each item appeared in my results.

So I used this...

SELECT COL1, COL2, ... ETC
       (1 / SELECT a.vcount 
            FROM (SELECT vm2.visit_id, count(*) AS vcount 
                  FROM dbo.visitmanifests AS vm2 
                  WHERE vm2.inactive = 0 AND vm2.visit_id = vm.Visit_ID 
                  GROUP BY vm2.visit_id) AS a)) AS [No of Visits],
       COL xyz
FROM etc etc

Of course you will need to format the result according to your display requirements.

I had this problem, even when I specified the correct minSDK and targetSDK version. My problem was, I was using "android:theme="@android:style/Theme.NoTitleBar.Fullscreen" in launcher activity, on Jellybean device. When I removed this attribute, it worked.

Your comparison function between old value and new value is having some issue. It is better not to complicate things so much, as it will increase your debugging effort later. You should keep it simple.

The best way is to create a person-component and watch every person separately inside its own component, as shown below:

<person-component :person="person" v-for="person in people"></person-component>

Please find below a working example for watching inside person component. If you want to handle it on parent side, you may use $emit to send an event upwards, containing the id of modified person.

I found that in my code when I used a ration or percentage for line-height line-height;1.5;

My page would scale in such a way that lower case font and upper case font would take up different page heights (I.E. All caps took more room than all lower). Normally I think this looks better, but I had to go to a fixed height line-height:24px; so that I could predict exactly how many pixels each page would take with a given number of lines.

JavaScript is a scripting language and therefore stays in human readable form until it is time for it to be interpreted and executed by the JavaScript runtime.

The only way to partially hide it, at least from the less technical minds, is to obfuscate.

Obfuscation makes it harder for humans to read it, but not impossible for the technically savvy.

$scope.$watch('myVar', function (newValue, oldValue) {
        if (typeof (newValue) !== 'undefined') {
            $scope.someothervar= newValue;
//or get some data
            getData();
        }


    }, true);

Variable initializes after controller so you need to watch over it and when it't initialized the use it.

There is another way to do this.

From iTerm2 2.9.20140923 you can use Dynamic Profiles as stated in the documentation page:

Dynamic Profiles is a feature that allows you to store your profiles in a file outside the usual macOS preferences database. Profiles may be changed at runtime by editing one or more plist files (formatted as JSON, XML, or in binary). Changes are picked up immediately.

So it is possible to create a file like this one:

    {
        "Profiles": [{
                "Name": "MYSERVER1",
                "Guid": "MYSERVER1",
                "Custom Command": "Yes",
                "Command": "ssh [email protected]",
                "Shortcut": "M",
                "Tags": [
                    "LOCAL", "THATCOMPANY", "WORK", "NOCLOUD"
                ],
                "Badge Text": "SRV1",
            },
            {
                "Name": "MYOCEANSERVER1",
                "Guid": "MYOCEANSERVER1",
                "Custom Command": "Yes",
                "Command": "ssh [email protected]",
                "Shortcut": "O",
                "Tags": [
                    "THATCOMPANY", "WORK", "DIGITALOCEAN"
                ],
                "Badge Text": "PPOCEAN1",
            },
            {
                "Name": "PI1",
                "Guid": "PI1",
                "Custom Command": "Yes",
                "Command": "ssh [email protected]",
                "Shortcut": "1",
                "Tags": [
                    "LOCAL", "PERSONAL", "RASPBERRY", "SMALL"
                ],
                "Badge Text": "LocalServer",
            },
            {
                "Name": "VUZERO",
                "Guid": "VUZERO",
                "Custom Command": "Yes",
                "Command": "ssh [email protected]",
                "Shortcut": "0",
                "Tags": [
                    "LOCAL", "PERSONAL", "SMALL"
                ],
                "Badge Text": "TeleVision",
            }
        ]
    }

in the folder ~/Library/Application\ Support/iTerm2/DynamicProfiles/ and share it across different machines. This enables you to retain some visual differences among iterm2 installations such as font type or dimension, while synchronising remote hosts, shortcuts, commands, and even a small badge to quickly identify a session

http://fetchak.com/ie-css3/ works for IE 6+. Use this if css3pie doesn't work for you.

In the current C++0x standard you can explicitly disable default constructors with the delete syntax, e.g.

MyClass() = delete;

Gcc 4.6 is the first version to support this syntax, so maybe that is the problem...

It's worth noting that the QuerySet.values_list() method doesn't actually return a list, but an object of type django.db.models.query.ValuesListQuerySet, in order to maintain Django's goal of lazy evaluation, i.e. the DB query required to generate the 'list' isn't actually performed until the object is evaluated.

Somewhat irritatingly, though, this object has a custom __repr__ method which makes it look like a list when printed out, so it's not always obvious that the object isn't really a list.

The exception in the question is caused by the fact that custom objects cannot be serialized in JSON, so you'll have to convert it to a list first, with...

my_list = list(self.get_queryset().values_list('code', flat=True))

...then you can convert it to JSON with...

json_data = json.dumps(my_list)

You'll also have to place the resulting JSON data in an HttpResponse object, which, apparently, should have a Content-Type of application/json, with...

response = HttpResponse(json_data, content_type='application/json')

...which you can then return from your function.

public Timestamp convertLocalTimeToServerDatetime(String dt,String timezone){

    String clientDnT = dt ;// "2017-06-01 07:20:00";
    try{
    SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
    Date date = sdf.parse(clientDnT);
    TimeZone tz = TimeZone.getTimeZone(timezone.trim()); // get time zone of user
    sdf.setTimeZone(tz);

    // Convert to servertime zone 
    SimpleDateFormat sdf1 = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
    TimeZone tzInAmerica = TimeZone.getDefault();
    sdf1.setTimeZone(tzInAmerica);

    // assign date to date
    String serverDate = sdf1.format(date);

    // Convert to servertime zone to Timestamp
    Date date2 =  sdf.parse(serverDate);
    Timestamp tsm = new Timestamp(date2.getTime());
    return  tsm;
    }
    catch(Exception e){
        System.err.println(e);
    }

    return null;
}

You can specify any amount of URLs on the command line. They will be fetched in a sequential manner in the specified order.

I had this problem. I'll share my ride on the learning curve.

First, I couldn't find how to reject the binary but remembered seeing it earlier today in the iTunesConnect App. So using the App I rejected the binary.

If you "mouse over" the rejected binary under the "Build" section you'll notice that a red circle icon with a - (i.e. a delete button) appears. Tap on this and then hit the save button at the top of the screen. Submitted binary is now gone.

You should now get all the notifications for the app being in state "Prepare for Upload" (email, App notification etc).

Xcode organiser was still giving me "Redundant Binary". After a bit of research I now understand the difference between "Version" & "Build". Version is what iTunes displays and the user sees. Build is just the internal tracking number. I had both at 2.3.0, I changed build to 2.3.0.1 and re-Archive. Now it validates and I can upload the new binary and re-submit. Hope that helps others!

This worked for me ! Go to Tools->Options(Last Item)->Color theme Drop down and select any

I don't know of Google voice, but using the javaScript speech SpeechSynthesisUtterance, you can add a click event to the element you are reference to. eg:

const listenBtn = document.getElementById('myvoice');

listenBtn.addEventListener('click', (e) => {
  e.preventDefault();

  const msg = new SpeechSynthesisUtterance(
    "Hello, hope my code is helpful"
  );
  window.speechSynthesis.speak(msg);

});

<button type="button" id='myvoice'>Listen to me</button>

You can use this command and will fetch all your key-stores, go to your terminal and in your android root directory run this:

./gradlew signingReport

it will give you something like this a list of key-store and their information:

You could always change the opacity of the image, given the difficulty of any alternatives this might be the best approach.

CSS:

.tinted { opacity: 0.8; }

If you're interested in better browser compatability, I suggest reading this:

http://css-tricks.com/css-transparency-settings-for-all-broswers/

If you're determined enough you can get this working as far back as IE7 (who knew!)

Note: As JGonzalezD points out below, this only actually darkens the image if the background colour is generally darker than the image itself. Although this technique may still be useful if you don't specifically want to darken the image, but instead want to highlight it on hover/focus/other state for whatever reason.

This can now be done as of docker-compose v2+ as part of the build object;

docker-compose.yml

version: '2'
services:
    my_image_name:
        build:
            context: . #current dir as build context
            args:
                var1: 1
                var2: c

See the docker compose docs.

In the above example "var1" and "var2" will be sent to the build environment.

Note: any env variables (specified by using the environment block) which have the same name as args variable(s) will override that variable.

Use the keys method: {"apple" => "fruit", "carrot" => "vegetable"}.keys == ["apple", "carrot"]

Hi you can make something like this:

1. Create class which implements AsyncTask

   // TASK 
   public class SomeClass extends AsyncTask<Void, Void, String>>
   {
   
       private OnTaskExecutionFinished _task_finished_event;
   
       public interface OnTaskExecutionFinished
       {
           public void OnTaskFihishedEvent(String Reslut);
       }
   
       public void setOnTaskFinishedEvent(OnTaskExecutionFinished _event)
       {
           if(_event != null)
           {
               this._task_finished_event = _event;
           }
       }
   
       @Override
       protected void onPreExecute()
       {
           super.onPreExecute();
   
       }
   
       @Override
       protected String doInBackground(Void... params)
       {
           // do your background task here ...
   
           return "Done!";
       }
   
       @Override
       protected void onPostExecute(String result)
       {
           super.onPostExecute(result);
           if(this._task_finished_event != null)
           {
               this._task_finished_event.OnTaskFihishedEvent(result);
           }
           else
           {
               Log.d("SomeClass", "task_finished even is null");
           }
       }
   }
   

2. Add in Main Activity

   // MAIN ACTIVITY
   public class MyActivity extends ListActivity
   {
      ...
       SomeClass _some_class = new SomeClass();
       _someclass.setOnTaskFinishedEvent(new _some_class.OnTaskExecutionFinished()
       {
       @Override
       public void OnTaskFihishedEvent(String result)
       {
           Toast.makeText(getApplicationContext(),
                   "Phony thread finished: " + result,
                   Toast.LENGTH_SHORT).show();
       }
   
      });
      _some_class.execute();
      ...
    }
   

You can use the markup below, but note that if you set the textAllCaps to true the underline effect would be removed.

<resource>
    <string name="my_string_value">I am <u>underlined</u>.</string>
</resources>

Note

Using textAllCaps with a string (login_change_settings) that contains markup; the markup will be dropped by the caps conversion

The textAllCaps text transform will end up calling toString on the CharSequence, which has the net effect of removing any markup such as . This check looks for usages of strings containing markup that also specify textAllCaps=true.

As of Notepad++ 5.9 they added a feature to 'Remove Unmarked Lines' which can be used to strip away everything that you don't want along with some search and replaces for the other text on each value line.

1. Use the Search-->Find-->Mark functionality to mark each line you want to keep/copy and remember to tick 'Bookmark Line' before marking the text
2. Select Search-->Bookmark-->Remove Unmarked Lines
3. Use Search-->Find-->Replace to replace other text you do not want to keep/copy with nothing
4. Save the remaining text or copy it.

You can also do a similar thing using Search-->Bookmark-->Copy Bookmarked Lines

So technically you still cannot copy marked text, but you can bookmark lines with marked text and then perform various operations on bookmarked or unmarked lines.

If the variable table contains invalid characters (like a space) you should add square brackets around the variable.

public DataTable fillDataTable(string table)
{
    string query = "SELECT * FROM dstut.dbo.[" + table + "]";

    using(SqlConnection sqlConn = new SqlConnection(conSTR))
    using(SqlCommand cmd = new SqlCommand(query, sqlConn))
    {
        sqlConn.Open();
        DataTable dt = new DataTable();
        dt.Load(cmd.ExecuteReader());
        return dt;
    }
}

By the way, be very careful with this kind of code because is open to Sql Injection. I hope for you that the table name doesn't come from user input

Wherever you have Text component in your page just you need to set style of the Text component.

 <Text style={{ textAlign: 'center' }}> Text here </Text>

you don't need to add any other styling property, this is spectacular magic it will set you text in center of the your UI.

In ASP.Net you can use System.Web.HttpUtility to safely encode the cookie value before writing to the cookie and convert it back to its original form on reading it out.

// Encode
HttpUtility.UrlEncode(cookieData);

// Decode
HttpUtility.UrlDecode(encodedCookieData);

This will stop ampersands and equals signs spliting a value into a bunch of name/value pairs as it is written to a cookie.

i had same problem. i updated to new version of VirtualBox 5.2.26 and checked to make sure Bridge Adapter was enabled in the installation process now is working

Unfortunately, it is quite difficult to accomplish this with the arrow keys, due to restrictions in KeyDown events. However, there are a few ways to get around this:

• As @Snarfblam stated, you can override the ProcessCmdKey method, which retains the ability to parse arrow key presses.
• As the accepted answer from this question states, XNA has a built-in method called Keyboard.GetState(), which allows you to use arrow key inputs. However, WinForms doesn't have this, but it can be done through a P/Invoke, or by using a class that helps with it.

I recommend trying to use that class. It's quite simple to do so:

var left = KeyboardInfo.GetKeyState(Keys.Left);
var right = KeyboardInfo.GetKeyState(Keys.Right);
var up = KeyboardInfo.GetKeyState(Keys.Up);
var down = KeyboardInfo.GetKeyState(Keys.Down);

if (left.IsPressed)
{
//do something...
}

//etc...

If you use this in combination with the KeyDown event, I think you can reliably accomplish your goal.

In case one wants to create FK constraints from UAT environment table to Live, fire below dynamic query.....

    SELECT 'ALTER TABLE '||OBJ.NAME||' ADD CONSTRAINT '||CONST.NAME||'     FOREIGN KEY ('||COALESCE(ACOL.NAME, COL.NAME)||') REFERENCES '

I ended up doing slightly different, since I was not happy with the other solutions. Basically I did not get them working as intended for some reason.

I did not want the splash to show for a fixed period of time, but rather as long as the MainForm was loading, and load time vary depending on how fast the connection toward the DB was.

In short my MainForm constructor spawn a thread that show my SplashForm, and on the event OnShown the splash thread is aborted. At first this did not work, and the SplashForm would at some times hang (hidden), and when closing the MainForm it would wait on the splash thread to exit. The solution was to catch the ThreadAbortException and call Dispose on the form.

Example code

private readonly Thread _splashThread = null;

public MainForm() {
    InitializeComponent();
    _splashThread = new Thread(new ThreadStart(DoSplash));
    _splashThread.Start();
}

private void DoSplash()
{
    var splashForm = new SplashForm();
    try
    {
        splashForm.ShowDialog();
    }
    catch (ThreadAbortException)
    {
        splashForm.Dispose();
    }
}

protected override void OnShown(EventArgs e)
{
    if (_splashThread != null && _splashThread.IsAlive)
    {
       _splashThread.Abort();
    }
    base.OnShown(e);
}

For Swift 3, Swift 4 (working with cellular and Wi-Fi):

import SystemConfiguration

public class Reachability {

    class func isConnectedToNetwork() -> Bool {

        var zeroAddress = sockaddr_in(sin_len: 0, sin_family: 0, sin_port: 0, sin_addr: in_addr(s_addr: 0), sin_zero: (0, 0, 0, 0, 0, 0, 0, 0))
        zeroAddress.sin_len = UInt8(MemoryLayout.size(ofValue: zeroAddress))
        zeroAddress.sin_family = sa_family_t(AF_INET)

        let defaultRouteReachability = withUnsafePointer(to: &zeroAddress) {
            $0.withMemoryRebound(to: sockaddr.self, capacity: 1) {zeroSockAddress in
                SCNetworkReachabilityCreateWithAddress(nil, zeroSockAddress)
            }
        }

        var flags: SCNetworkReachabilityFlags = SCNetworkReachabilityFlags(rawValue: 0)
        if SCNetworkReachabilityGetFlags(defaultRouteReachability!, &flags) == false {
            return false
        }

        /* Only Working for WIFI
        let isReachable = flags == .reachable
        let needsConnection = flags == .connectionRequired

        return isReachable && !needsConnection
        */

        // Working for Cellular and WIFI
        let isReachable = (flags.rawValue & UInt32(kSCNetworkFlagsReachable)) != 0
        let needsConnection = (flags.rawValue & UInt32(kSCNetworkFlagsConnectionRequired)) != 0
        let ret = (isReachable && !needsConnection)

        return ret

    }
}

Usage:

if Reachability.isConnectedToNetwork(){
    print("Internet Connection Available!")
}else{
    print("Internet Connection not Available!")
}

You can change the aspectRatio according to your needs:

options:{
     aspectRatio:4 //(width/height)
}

sign = lambda x: (1, -1)[x < 0]
def frange(start, stop, step):
    i = 0
    r=len(str(step).split('.')[-1])
    args=(start,stop,step)
    if not step :return []
    if all(int(i)==float(i) for i in args):
        start,stop,step=map(int,args)
    if sign(step)==1:
        while start + i * step < stop:
            yield round(start + i * step,r)
            i += 1
    else:
        while start + i * step > stop:
            yield round(start + i * step,r)
            i += 1

our project surely is configured as "library" thats why you get the message : "Android library projects cannot be launched."

right-click in your project and select Properties. In the Properties window -> "Android" -> uncheck the option "is Library" and apply -> Click "ok" to close the properties window.

In newer version of git (2.23+) you can use:

git switch -C master origin/master

-C is same as --force-create. Related Reference Docs

Very useful. I modified it to copy a JavaScript variable value to clipboard:

function copyToClipboard(val){
    var dummy = document.createElement("input");
    dummy.style.display = 'none';
    document.body.appendChild(dummy);

    dummy.setAttribute("id", "dummy_id");
    document.getElementById("dummy_id").value=val;
    dummy.select();
    document.execCommand("copy");
    document.body.removeChild(dummy);
}

Don't listen to every people telling you that namespaces are just name-spaces.

They are important because they are considered by the compiler to apply the interface principle. Basically, it can be explained by an example:

namespace ns {

class A
{
};

void print(A a)
{
}

}

If you wanted to print an A object, the code would be this one:

ns::A a;
print(a);

Note that we didn't explicitly mention the namespace when calling the function. This is the interface principle: C++ consider a function taking a type as an argument as being part of the interface for that type, so no need to specify the namespace because the parameter already implied the namespace.

Now why this principle is important? Imagine that the class A author did not provide a print() function for this class. You will have to provide one yourself. As you are a good programmer, you will define this function in your own namespace, or maybe in the global namespace.

namespace ns {

class A
{
};

}

void print(A a)
{
}

And your code can start calling the print(a) function wherever you want. Now imagine that years later, the author decides to provide a print() function, better than yours because he knows the internals of his class and can make a better version than yours.

Then C++ authors decided that his version of the print() function should be used instead of the one provided in another namespace, to respect the interface principle. And that this "upgrade" of the print() function should be as easy as possible, which means that you won't have to change every call to the print() function. That's why "interface functions" (function in the same namespace as a class) can be called without specifying the namespace in C++.

And that's why you should consider a C++ namespace as an "interface" when you use one and keep in mind the interface principle.

If you want better explanation of this behavior, you can refer to the book Exceptional C++ from Herb Sutter

Your debut and fin values are floating point values, not integers, because taille is a float.

Make those values integers instead:

item = plateau[int(debut):int(fin)]

Alternatively, make taille an integer:

taille = int(sqrt(len(plateau)))

It depends on the nature of your site.

I happen to work on a bit of software where IP tracking is important, and within a field consumed by parter sites I'd guess some 20% - 40% of requests are either detectably spoofed IPs or headers blanked out, depending on the time of day and where they came from. For a site which gets organic traffic (i.e. not through partners) I'd expect a much higher ratio of good IPs.

As Kosi said, be careful what you're doing with this - IPs are in no way a reliable way to identify unique visitors.

Leaving database modeling issues aside. I think you can try

SELECT * FROM STUDENTS WHERE ISNUMERIC(STUDENTID) = 0

But ISNUMERIC returns 1 for any value that seems numeric including things like -1.0e5

If you want to exclude digit-only studentids, try something like

SELECT * FROM STUDENTS WHERE STUDENTID LIKE '%[^0-9]%'

I had mostly the same problem and ended up a a different solution that makes this type of problem trivial to query.

I have a table of sensor data (1 minute data from about 30 sensors)

SensorReadings->(timestamp,value,idSensor)

and I have a sensor table that has lots of mostly static stuff about the sensor but the relevant fields are these:

Sensors->(idSensor,Description,tvLastUpdate,tvLastValue,...)

The tvLastupdate and tvLastValue are set in a trigger on inserts to the SensorReadings table. I always have direct access to these values without needing to do any expensive queries. This does denormalize slightly. The query is trivial:

SELECT idSensor,Description,tvLastUpdate,tvLastValue 
FROM Sensors

I use this method for data that is queried often. In my case I have a sensor table, and a large event table, that have data coming in at the minute level AND dozens of machines are updating dashboards and graphs with that data. With my data scenario the trigger-and-cache method works well.

So,

Steps to follow in order to import a JAR sucesfully to your project using Android Studio 0.1.1:

• Download the library.jar file and copy it to your /libs/ folder inside your application project.
• Open the build.gradle file and edit your dependencies to include the new .jar file:

compile files('libs/android-support-v4.jar', 'libs/GoogleAdMobAdsSdk-6.4.1.jar')

• File -> Close Project
• Open a command prompt on your project's root location, i.e 'C:\Users\Username\AndroidStudioProjects\MyApplicationProject\'
• On the command prompt, type gradlew clean, wait till it's done.
• Reopen your application project in Android Studio.
• Test run your application and it should work succesfully.

The delete operator deallocates memory and calls the destructor for a single object created with new.

The delete [] operator deallocates memory and calls destructors for an array of objects created with new [].

Using delete on a pointer returned by new [] or delete [] on a pointer returned by new results in undefined behavior.

There are two ways to do the same instruction, that is, an empty string. The first way is to allocate an empty string on static memory:

char* my_variable = "";

or, if you want to be explicit:

char my_variable = '\0';

The way posted above is only for a character. And, the second way:

#include <string.h>
char* my_variable = strdup("");

Don't forget to use free() with this one because strdup() use malloc inside.

I modified the script tag to point to the right content and changed the script order to be the right one in the editor. But totally forgot to save the change.

You also need to configure and start the MySQL server. This will probably help

I think you're asking how to compute the mean of a variable in a data frame, given the name of the column. There are two typical approaches to doing this, one indexing with [[ and the other indexing with [:

data(iris)
mean(iris[["Petal.Length"]])
# [1] 3.758
mean(iris[,"Petal.Length"])
# [1] 3.758
mean(iris[["Sepal.Width"]])
# [1] 3.057333
mean(iris[,"Sepal.Width"])
# [1] 3.057333

It's really easy to do this, simply send the file via an XHR request inside of the file input's onchange handler.

<input id="myFileInput" type="file" accept="image/*;capture=camera">

var myInput = document.getElementById('myFileInput');

function sendPic() {
    var file = myInput.files[0];

    // Send file here either by adding it to a `FormData` object 
    // and sending that via XHR, or by simply passing the file into 
    // the `send` method of an XHR instance.
}

myInput.addEventListener('change', sendPic, false);

I have encased the 'problem div in another div' lets call this div the enclose div... make the enclose div in css have a width of 100% and postion fixed with a bottom of 0... then insert the problem div into the enclose div this is how it would look

#problem {margin-right:auto;margin-left:auto; /*what ever other styles*/}
#enclose {position:fixed;bottom:0px;width:100%;}

then in html...

<div id="enclose">
    <div id="problem">
    <!--this is where the text/markup would go-->
    </div>
</div>

There ya go!

Communicating between different JavaScript execution context was supported even before HTML5 if the documents was of the same origin. If not or you have no reference to the other Window object, then you could use the new postMessage API introduced with HTML5. I elaborated a bit on both approaches in this stackoverflow answer.

Here's an improvement, grabbing just the directory to stdout:

java -XshowSettings:properties -version 2>&1 \
   | sed '/^[[:space:]]*java\.home/!d;s/^[[:space:]]*java\.home[[:space:]]*=[[:space:]]*//'

According to the source code, the maximum size of a list is PY_SSIZE_T_MAX/sizeof(PyObject*).

PY_SSIZE_T_MAX is defined in pyport.h to be ((size_t) -1)>>1

On a regular 32bit system, this is (4294967295 / 2) / 4 or 536870912.

Therefore the maximum size of a python list on a 32 bit system is 536,870,912 elements.

As long as the number of elements you have is equal or below this, all list functions should operate correctly.

In my case Right Click on Virtual Directory and Select "Convert To Application" worked!

For Python 2.5 and newer there is a specific syntax:

[on_true] if [cond] else [on_false]

In older Pythons a ternary operator is not implemented but it's possible to simulate it.

cond and on_true or on_false

Though, there is a potential problem, which if cond evaluates to True and on_true evaluates to False then on_false is returned instead of on_true. If you want this behavior the method is OK, otherwise use this:

{True: on_true, False: on_false}[cond is True] # is True, not == True

which can be wrapped by:

def q(cond, on_true, on_false)
    return {True: on_true, False: on_false}[cond is True]

and used this way:

q(cond, on_true, on_false)

It is compatible with all Python versions.

Look at section 22.4 of Steven's Unix Network Programming, "When to Use UDP Instead of TCP".

Also, see this other SO answer about the misconception that UDP is always faster than TCP.

What Steven's says can be summed up as follows:

• Use UDP for broadcast and multicast since that is your only option ( use multicast for any new apps )
• You can use UDP for simple request / reply apps, but you'll need to build in your own acks, timeouts and retransmissions
• Don't use UDP for bulk data transfer.

I had the same error because I was using proxy. As the answer is given but in case you are using proxy then please set your proxy first using these commands:

git config --global http.proxy http://proxy_username:proxy_password@proxy_ip:port
git config --global https.proxy https://proxy_username:proxy_password@proxy_ip:port

If you updated Xcode to 12.1. Completely quit Xcode and it will install components.

Use Tkinter there are a ton of tutorials online for this. basically, you can create events. Here is a link to a great site! This makes it easy to capture clicks. Also, if you are trying to make a game, Tkinter also has a GUI. Although, I wouldn't recommend Python for games at all, it could be a fun experiment. Good Luck!

I recently came across Python 3 interpreter at CompileOnline.

This is my code:

import {Pipe, PipeTransform, Injectable} from '@angular/core';

@Pipe({
    name: 'filter'
})
@Injectable()
export class FilterPipe implements PipeTransform {
    transform(items: any[], field : string, value): any[] {
      if (!items) return [];
      if (!value || value.length === 0) return items;
      return items.filter(it =>
      it[field] === value);
    }
}

Sample:

LIST = [{id:1,name:'abc'},{id:2,name:'cba'}];
FilterValue = 1;

<span *ngFor="let listItem of LIST | filter : 'id' : FilterValue">
                              {{listItem .name}}
                          </span>

byte[] result = new byte[a.length + b.length];
// copy a to result
System.arraycopy(a, 0, result, 0, a.length);
// copy b to result
System.arraycopy(b, 0, result, a.length, b.length);

Type checking

You can check the type of variable by using typeof operator:

typeof variable

Value checking

The code below returns true for numbers and false for anything else:

!isNaN(+variable);

Had the same problem. For me it worked to call

viewPage.setAdapter( adapter );

again which caused reinstantiating the pages again.

Here is an example to fully programmatically:

• init a Spinner.
• fill it with data via a String List.
• resize the Spinner and add it to my View.
• format the Spinner font (font size, colour, padding).
• clear the Spinner.
• add new values to the Spinner.
• redraw the Spinner.

I am using the following class vars:

Spinner varSpinner;
List<String> varSpinnerData;

float varScaleX;
float varScaleY;    

A - Init and render the Spinner (varRoot is a pointer to my main Activity):

public void renderSpinner() {


    List<String> myArraySpinner = new ArrayList<String>();

    myArraySpinner.add("red");
    myArraySpinner.add("green");
    myArraySpinner.add("blue");     

    varSpinnerData = myArraySpinner;

    Spinner mySpinner = new Spinner(varRoot);               

    varSpinner = mySpinner;

    ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>(varRoot, android.R.layout.simple_spinner_item, myArraySpinner);
    spinnerArrayAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); // The drop down vieww
    mySpinner.setAdapter(spinnerArrayAdapter);

B - Resize and Add the Spinner to my View:

    FrameLayout.LayoutParams myParamsLayout = new FrameLayout.LayoutParams(
            FrameLayout.LayoutParams.MATCH_PARENT, 
            FrameLayout.LayoutParams.WRAP_CONTENT);
    myParamsLayout.gravity = Gravity.NO_GRAVITY;             

    myParamsLayout.leftMargin = (int) (100 * varScaleX);
    myParamsLayout.topMargin = (int) (350 * varScaleY);             
    myParamsLayout.width = (int) (300 * varScaleX);;
    myParamsLayout.height = (int) (60 * varScaleY);;


    varLayoutECommerce_Dialogue.addView(mySpinner, myParamsLayout);

C - Make the Click handler and use this to set the font.

    mySpinner.setOnItemSelectedListener(new OnItemSelectedListener() {

        @Override
        public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int myPosition, long myID) {

            Log.i("renderSpinner -> ", "onItemSelected: " + myPosition + "/" + myID);

            ((TextView) parentView.getChildAt(0)).setTextColor(Color.GREEN);
            ((TextView) parentView.getChildAt(0)).setTextSize(TypedValue.COMPLEX_UNIT_PX, (int) (varScaleY * 22.0f) );
            ((TextView) parentView.getChildAt(0)).setPadding(1,1,1,1);


        }

        @Override
        public void onNothingSelected(AdapterView<?> parentView) {
            // your code here
        }

    });

}   

D - Update the Spinner with new data:

private void updateInitSpinners(){

     String mySelected = varSpinner.getSelectedItem().toString();
     Log.i("TPRenderECommerce_Dialogue -> ", "updateInitSpinners -> mySelected: " + mySelected);


     varSpinnerData.clear();

     varSpinnerData.add("Hello World");
     varSpinnerData.add("Hello World 2");

     ((BaseAdapter) varSpinner.getAdapter()).notifyDataSetChanged();
     varSpinner.invalidate();
     varSpinner.setSelection(1);

}

}

What I have not been able to solve in the updateInitSpinners, is to do varSpinner.setSelection(0); and have the custom font settings activated automatically.

UPDATE:

This "ugly" solution solves the varSpinner.setSelection(0); issue, but I am not very happy with it:

private void updateInitSpinners(){

    String mySelected = varSpinner.getSelectedItem().toString();
    Log.i("TPRenderECommerce_Dialogue -> ", "updateInitSpinners -> mySelected: " + mySelected);


    varSpinnerData.clear();

    ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>(varRoot, android.R.layout.simple_spinner_item, varSpinnerData);
    spinnerArrayAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); 
    varSpinner.setAdapter(spinnerArrayAdapter);  


    varSpinnerData.add("Hello World");
    varSpinnerData.add("Hello World 2");

    ((BaseAdapter) varSpinner.getAdapter()).notifyDataSetChanged();
    varSpinner.invalidate();
    varSpinner.setSelection(0);

}

}

Hope this helps......

I changed a few things to work with Option Explicit, and the code ran fine against a cell containing "abc.123", which returned "abc.12,". There were no compile errors.

Option Explicit ' This is new

Public Function ProcessString(input_string As String) As String
    ' The temp string used throughout the function
    Dim temp_string As String
    Dim i As Integer ' This is new
    Dim return_string As String ' This is new
    For i = 1 To Len(input_string)
        temp_string = Mid(input_string, i, 1)
        If temp_string Like "[A-Z, a-z, 0-9, :, -]" Then
            return_string = return_string & temp_string
        End If
    Next i
    return_string = Mid(return_string, 1, (Len(return_string) - 1))
    ProcessString = return_string & ", "
End Function

I'll suggest you post more of your relevant code (that calls this function). You've stated that last_name is a String, but it appears that may not be the case. Step through your code line by line and ensure that this is actually the case.

Add following lines to your .vimrc

set expandtab
set tabstop=4
set shiftwidth=4
map <F2> :retab <CR> :wq! <CR>

Open a file in vim and press F2 The tabs will be converted to 4 spaces and file will be saved automatically.

You can create the sql to update all tables with:

SELECT CONCAT("ALTER TABLE ",TABLE_SCHEMA,".",TABLE_NAME," CHARACTER SET utf8 COLLATE utf8_general_ci;   ",
    "ALTER TABLE ",TABLE_SCHEMA,".",TABLE_NAME," CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;  ") 
    AS alter_sql
FROM information_schema.TABLES
WHERE TABLE_SCHEMA = "your_database_name";

Capture the output and run it.

Arnold Daniels' answer above is more elegant.

You could instantiate the values from a dictionary if you wanted different values for each column & you don't mind making a dictionary on the line before.

>>> import pandas as pd
>>> import numpy as np
>>> df = pd.DataFrame({
  'col_1': [0, 1, 2, 3], 
  'col_2': [4, 5, 6, 7]
})
>>> df
   col_1  col_2
0      0      4
1      1      5
2      2      6
3      3      7
>>> cols = {
  'column_new_1':np.nan,
  'column_new_2':'dogs',
  'column_new_3': 3
}
>>> df[list(cols)] = pd.DataFrame(data={k:[v]*len(df) for k,v in cols.items()})
>>> df
   col_1  col_2  column_new_1 column_new_2  column_new_3
0      0      4           NaN         dogs             3
1      1      5           NaN         dogs             3
2      2      6           NaN         dogs             3
3      3      7           NaN         dogs             3

Not necessarily better than the accepted answer, but it's another approach not yet listed.

I found 1 solution. if want to translate this kind of SQL (left join) into Linq Entity...

SQL:

SELECT * FROM [JOBBOOKING] AS [t0]
LEFT OUTER JOIN [REFTABLE] AS [t1] ON ([t0].[trxtype] = [t1].[code])
                                  AND ([t1]. [reftype] = "TRX")

LINQ:

from job in JOBBOOKINGs
join r in (from r1 in REFTABLEs where r1.Reftype=="TRX" select r1) 
          on job.Trxtype equals r.Code into join1
from j in join1.DefaultIfEmpty()
select new
{
   //cols...
}

You mean that you want something like:

''.join(n for n in phone_str if n.isdigit())

This uses the fact that strings are iterable. They yield 1 character at a time when you iterate over them.

Regarding your efforts,

This one actually removes all of the digits from the string leaving you with only non-digits.

x = row.translate(None, string.digits)

This one splits the string on runs of whitespace, not after each character:

list = x.split()

You can't secure client side code: just press F12 on Google Chrome, pause javascript execution and you will get all strings, even those encrypted. Beautify it and rename variables and you will get almost the original code.

If you're writing server side javascript (i.e. NodeJS) is afraid of someone hacking into your server and want to make the hacker work more difficult, giving you more time to get your access back, then use javacript compilers:

You need to use Closure Compiler on Advanced Compilation, as it's the only tool that renames all your variables, even if those are used in multiple files/modules. But it just have a problem: it only work if you write in it's coding style.

In your statement, you are comparing a string called start_date with the time.
If start_date is a column, it should either be

 
  SELECT * FROM `la_schedule` WHERE start_date >'2012-11-18';
 

(no apostrophe) or

SELECT * FROM `la_schedule` WHERE `start_date` >'2012-11-18';

(with backticks).

Hope this helps.

Best as an out parameter:

void testfunc(char* outStr){
  char str[10];
  for(int i=0; i < 10; ++i){
    outStr[i] = str[i];
  }
}

Called with

int main(){
  char myStr[10];
  testfunc(myStr);
  // myStr is now filled
}

You can also use array concatenation:

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

This creates a new array and doesn't modify the original.

Yes. But you can't redefine built-in types. You have to subclass them:

class MyTuple(tuple):
    def __add__(self, other):
         if len(self) != len(other):
             raise ValueError("tuple lengths don't match")
         return MyTuple(x + y for (x, y) in zip(self, other))

I wasn't happy with any of the awk solutions presented here because I wanted to extract the first few columns and then print the rest, so I turned to perl instead. The following code extracts the first two columns, and displays the rest as is:

echo -e "a  b  c  d\te\t\tf g" | \
  perl -ne 'my @f = split /\s+/, $_, 3; printf "first: %s second: %s rest: %s", @f;'

The advantage compared to the perl solution from Chris Koknat is that really only the first n elements are split off from the input string; the rest of the string isn't split at all and therefor stays completely intact. My example demonstrates this with a mix of spaces and tabs.

To change the amount of columns that should be extracted, replace the 3 in the example with n+1.

I want to give my resolution, it work when i replace the line [session = tf.Session()] with [sess = tf.InteractiveSession()]. Hope this will be useful to others.

Note that both pcolor and "surf + view(2)" do not show the last row and the last column of your 2D data.

On the other hand, using imagesc, you have to be careful with the axes. The surf and the imagesc examples in gevang's answer only (almost -- apart from the last row and column) correspond to each other because the 2D sinc function is symmetric.

To illustrate these 2 points, I produced the figure below with the following code:

[x, y] = meshgrid(1:10,1:5);
z      = x.^3 + y.^3;

subplot(3,1,1)
imagesc(flipud(z)), axis equal tight, colorbar
set(gca, 'YTick', 1:5, 'YTickLabel', 5:-1:1);
title('imagesc')

subplot(3,1,2)
surf(x,y,z,'EdgeColor','None'), view(2), axis equal tight, colorbar
title('surf with view(2)')

subplot(3,1,3)
imagesc(flipud(z)), axis equal tight, colorbar
axis([0.5 9.5 1.5 5.5])
set(gca, 'YTick', 1:5, 'YTickLabel', 5:-1:1);
title('imagesc cropped')

colormap jet

As you can see the 10th row and 5th column are missing in the surf plot. (You can also see this in images in the other answers.)

Note how you can use the "set(gca, 'YTick'..." (and Xtick) command to set the x and y tick labels properly if x and y are not 1:1:N.

Also note that imagesc only makes sense if your z data correspond to xs and ys are (each) equally spaced. If not you can use surf (and possibly duplicate the last column and row and one more "(end,end)" value -- although that's a kind of a dirty approach).

use Date function directly. Hope it works

http://www.selectorgadget.com/ is a bookmarklet designed explicitly for this use case.

That said, I agree with most other people in that you should just learn CSS selectors yourself, trying to generate them with code is not sustainable. :)

ALTER TABLE (Your_Table_Name) MODIFY (Your_Column_Name) DATA_TYPE();

For you problem:

ALTER TABLE (Your_Table_Name) MODIFY (Your_Column_Name) DECIMAL(Precision, Scale); 

This is a just a nice idea. that, you can Add class in body, and hide/show table while there is no data in table. This works perfect for me. You can design custom NO Record Found error message when there is no record in table, you can add class "no-record", and when there is 1 or more than one record, you can remove class and show datatable

Here is jQuery code.

$('#default_table').DataTable({

    // your stuff here

    "fnFooterCallback": function (nRow, aaData, iStart, iEnd, aiDisplay) {
        if (aiDisplay.length > 0) {
            $('body').removeClass('no-record');
        }
        else {
            $('body').addClass('no-record');
        }
    }
});

Here is CSS

.no-record #default_table{display:none;}

and here is Official link.

For limit 1 use methods FirstOrDefault() or First().

Example

var y = (from x in q select x).FirstOrDefault();

this answer is based on Shamil Yakupov answer, with real object instead of string.

using System.Dynamic;

dynamic response = new ExpandoObject();
response.message = "Email address already exist";

return Content<object>(HttpStatusCode.BadRequest, response);

I also highly recommend using

int integer = 42;
String string = integer + "";

Simple and effective.

I really don't know what was so hard about this question, but I managed to do it this way:

[myStringContainingInt intValue];

It should be noted that you can also do:

myStringContainingInt.intValue;

To calculate gradients, the machine learning community uses Autograd:

"Efficiently computes derivatives of numpy code."

To install:

pip install autograd

Here is an example:

import autograd.numpy as np
from autograd import grad

def fct(x):
    y = x**2+1
    return y

grad_fct = grad(fct)
print(grad_fct(1.0))

It can also compute gradients of complex functions, e.g. multivariate functions.

You can use the following command:
:%s/^V^M//g
where the '^' means use CTRL key.

PowerShell 3 has the $PSScriptRoot automatic variable:

Contains the directory from which a script is being run.

In Windows PowerShell 2.0, this variable is valid only in script modules (.psm1). Beginning in Windows PowerShell 3.0, it is valid in all scripts.

Don't be fooled by the poor wording. PSScriptRoot is the directory of the current file.

In PowerShell 2, you can calculate the value of $PSScriptRoot yourself:

# PowerShell v2
$PSScriptRoot = Split-Path -Parent -Path $MyInvocation.MyCommand.Definition

If you're using Windows and this has suddenly started happening on out of the blue on GitHub, it's probably due to GitHub's recent disabling support for deprecated cryptographic algorithms on 2018-02-22, in which case the solution is simply to download and install the latest version of either the full Git for Windows or just the Git Credential Manager for Windows.

The problem is that your PATH does not include the location of the node executable.

You can likely run node as "/usr/local/bin/node".

You can add that location to your path by running the following command to add a single line to your bashrc file:

echo 'export PATH=$PATH:/usr/local/bin' >> $HOME/.bashrc

If you want to use scrollWidth to get the "REAL" CONTENT WIDTH/HEIGHT (as content can be BIGGER than the css-defined width/height-Box) the scrollWidth/Height is very UNRELIABLE as some browser seem to "MOVE" the paddingRIGHT & paddingBOTTOM if the content is to big. They then place the paddings at the RIGHT/BOTTOM of the "too broad/high content" (see picture below).

==> Therefore to get the REAL CONTENT WIDTH in some browsers you have to substract BOTH paddings from the scrollwidth and in some browsers you only have to substract the LEFT Padding.

I found a solution for this and wanted to add this as a comment, but was not allowed. So I took the picture and made it a bit clearer in the regard of the "moved paddings" and the "unreliable scrollWidth". In the BLUE AREA you find my solution on how to get the "REAL" CONTENT WIDTH!

Hope this helps to make things even clearer!

The mainstream is, as other answers here already pointed out, probably going with the Sphinx way so that you can use Sphinx to generate those fancy documents later.

That being said, I personally go with inline comment style occasionally.

def complex(  # Form a complex number
        real=0.0,  # the real part (default 0.0)
        imag=0.0  # the imaginary part (default 0.0)
        ):  # Returns a complex number.
    """Form a complex number.

    I may still use the mainstream docstring notation,
    if I foresee a need to use some other tools
    to generate an HTML online doc later
    """
    if imag == 0.0 and real == 0.0:
        return complex_zero
    other_code()

One more example here, with some tiny details documented inline:

            # The "inline" text does not really have to be at same line,

            # Some more description about parameter B.
            # As you probably noticed, the vertical alignment of pound sign

        ):  # So this ending parenthesis occupying its own line provides a
            # perfect chance to use inline doc to document the return value,
            # despite of its unhappy face appearance. :)
    pass

The benefits (as @mark-horvath already pointed out in another comment) are:

• Most importantly, parameters and their doc always stay together, which brings the following benefits:
• Less typing (no need to repeat variable name)
• Easier maintenance upon changing/removing variable. There will never be some orphan parameter doc paragraph after you rename some parameter.
• and easier to find missing comment.

Now, some may think this style looks "ugly". But I would say "ugly" is a subjective word. A more neutual way is to say, this style is not mainstream so it may look less familiar to you, thus less comfortable. Again, "comfortable" is also a subjective word. But the point is, all the benefits described above are objective. You can not achieve them if you follow the standard way.

Hopefully some day in the future, there will be a doc generator tool which can also consume such inline style. That will drive the adoption.

PS: This answer is derived from my own preference of using inline comments whenever I see fit. I use the same inline style to document a dictionary too.

Since 0.14.1, you can now do nlargest and nsmallest on a groupby object:

In [23]: df.groupby('id')['value'].nlargest(2)
Out[23]: 
id   
1   2    3
    1    2
2   6    4
    5    3
3   7    1
4   8    1
dtype: int64

There's a slight weirdness that you get the original index in there as well, but this might be really useful depending on what your original index was.

If you're not interested in it, you can do .reset_index(level=1, drop=True) to get rid of it altogether.

(Note: From 0.17.1 you'll be able to do this on a DataFrameGroupBy too but for now it only works with Series and SeriesGroupBy.)

Actually you don't even need the block:

  Dir.chdir 'C:/Users/name/Music'
  music = Dir['C:/Users/name/Music/*.{mp3, MP3}']
  puts 'what would you like to call the playlist?'
  playlist_name = gets.chomp + '.m3u'

  File.open(playlist_name, 'w').puts(music)

Sed is a little ugly, you could do it elegantly like so:

hendry@i7 tmp$ cat foo 
bar
candy
car
hendry@i7 tmp$ for i in `cat foo`; do echo ${i}bar; done
barbar
candybar
carbar

It's been quite sometime since I asked this question. Now I understand it more clearly, I'm going to put a more complete answer to help others.

In Web API, it's very simple to remember how parameter binding is happening.

• if you POST simple types, Web API tries to bind it from the URL

• if you POST complex type, Web API tries to bind it from the body of the request (this uses a media-type formatter).

• If you want to bind a complex type from the URL, you'll use [FromUri] in your action parameter. The limitation of this is down to how long your data going to be and if it exceeds the url character limit.

  public IHttpActionResult Put([FromUri] ViewModel data) { ... }

• If you want to bind a simple type from the request body, you'll use [FromBody] in your action parameter.

  public IHttpActionResult Put([FromBody] string name) { ... }

as a side note, say you are making a PUT request (just a string) to update something. If you decide not to append it to the URL and pass as a complex type with just one property in the model, then the data parameter in jQuery ajax will look something like below. The object you pass to data parameter has only one property with empty property name.

var myName = 'ABC';
$.ajax({url:.., data: {'': myName}});

and your web api action will look something like below.

public IHttpActionResult Put([FromBody] string name){ ... }

This asp.net page explains it all. http://www.asp.net/web-api/overview/formats-and-model-binding/parameter-binding-in-aspnet-web-api

You can do in this way:

    Integer i = 1;
    new BigInteger("" + i);

You could use a shortcut library to handle the browser specific stuff.

shortcut.add("Ctrl+S",function() {
    alert("Hi there!");
});

This does not work in Chrome Developer tools to locate a element, i am looking to locate the 'Submit' button in the screen

//input[matches(@value,'submit','i')]

However, using 'translate' to replace all caps to small works as below

//input[translate(@value,'ABCDEFGHIJKLMNOPQRSTUVWXYZ','abcdefghijklmnopqrstuvwxyz') = 'submit']

Update: I just found the reason why 'matches' doesnt work. I am using Chrome with xpath 1.0 which wont understand the syntax 'matches'. It should be xpath 2.0

In this link explain about @model, see a excerpt:

@model (lowercase "m") is a reserved keyword in Razor views to declare the model type at the top of your view. You have put the namespace too, e.g.: @model MyNamespace.Models.MyModel

Later in the file, you can reference the attribute you want with @Model.Attribute (uppercase "M").

The displayed error

after that import react

Finally import react-dom

if error is react is not define,please add ==>import React from 'react';

if error is reactDOM is not define,please add ==>import ReactDOM from 'react-dom';

I use this function to calculate cpu usage. Hope it can help you.

private float readUsage() {
    try {
        RandomAccessFile reader = new RandomAccessFile("/proc/stat", "r");
        String load = reader.readLine();

        String[] toks = load.split(" +");  // Split on one or more spaces

        long idle1 = Long.parseLong(toks[4]);
        long cpu1 = Long.parseLong(toks[2]) + Long.parseLong(toks[3]) + Long.parseLong(toks[5])
              + Long.parseLong(toks[6]) + Long.parseLong(toks[7]) + Long.parseLong(toks[8]);

        try {
            Thread.sleep(360);
        } catch (Exception e) {}

        reader.seek(0);
        load = reader.readLine();
        reader.close();

        toks = load.split(" +");

        long idle2 = Long.parseLong(toks[4]);
        long cpu2 = Long.parseLong(toks[2]) + Long.parseLong(toks[3]) + Long.parseLong(toks[5])
            + Long.parseLong(toks[6]) + Long.parseLong(toks[7]) + Long.parseLong(toks[8]);

        return (float)(cpu2 - cpu1) / ((cpu2 + idle2) - (cpu1 + idle1));

    } catch (IOException ex) {
        ex.printStackTrace();
    }

    return 0;
} 

This might be seen as a little complex but does exactly what you want

SELECT 
  DISTINCT(p.`ProductID`) AS ProductID,
  SUM(pl.CashAmount) AS Cash,
  SUM(pr.CashAmount) AS `Check`,
  SUM(px.CashAmount) AS `Credit Card`,
  SUM(pl.CashAmount) + SUM(pr.CashAmount) +SUM(px.CashAmount) AS Amount
FROM
  `payments` AS p 
  LEFT JOIN (SELECT ProductID,PaymentMethod , IFNULL(Amount,0) AS CashAmount FROM payments WHERE PaymentMethod = 'Cash' GROUP BY ProductID , PaymentMethod ) AS pl 
    ON pl.`PaymentMethod` = p.`PaymentMethod` AND pl.ProductID = p.`ProductID`
  LEFT JOIN (SELECT ProductID,PaymentMethod , IFNULL(Amount,0) AS CashAmount FROM payments WHERE PaymentMethod = 'Check' GROUP BY ProductID , PaymentMethod) AS pr 
    ON pr.`PaymentMethod` = p.`PaymentMethod` AND pr.ProductID = p.`ProductID`
  LEFT JOIN (SELECT ProductID, PaymentMethod , IFNULL(Amount,0) AS CashAmount FROM payments WHERE PaymentMethod = 'Credit Card' GROUP BY ProductID , PaymentMethod) AS px 
    ON px.`PaymentMethod` = p.`PaymentMethod` AND px.ProductID = p.`ProductID`
GROUP BY p.`ProductID` ;

Output

ProductID | Cash | Check | Credit Card | Amount
-----------------------------------------------
    3     | 20   |  15   |   25        |  60
    4     | 5    |  6    |   7         |  18

SQL Fiddle Demo

Regarding a previous answer, setting html and body to height: 100% doesn't seem to work if the content needs to scroll. Adding fixed to the background seems to fix that - no need for height: 100%;

E.g.:

body {_x000D_
  background: -webkit-gradient(linear, left top, left bottom, from(#fff), to(#cbccc8)) fixed;_x000D_
}

You need to check the keycloak admin console for fronted configuration. It must be wrongly configured for redirect url and web origins.

You can, the question in my mind is more should you. Right from the beginning, I'll say that there is no hard and fast answer. Do the right thing for your current situation.

To me inheritance implies an 'is-a' relationship. Imagine a dog class, which can be extended by more specialized sub types (Alsatian, Poodle, etc). In this case making the dog class abstract may be the right thing to do since sub-types are dogs. Now let's imagine that dogs need a collar. In this case inheritance doesn't make sense: it's nonsense to have a 'is-a' relationship between dogs and collars. This is definitely a 'has-a' relationship, collar is a collaborating object. Making collar abstract just so that dogs can have one doesn't make sense.

I often find that abstract classes with no abstract methods are really expressing a 'has-a' relationship. In these cases I usually find that the code can be better factored without using inheritance. I also find that abstract classes with no abstract method are often a code smell and at the very least should lead to questions being raised in a code review.

Again, this is entirely subjective. There may well be situations when an abstract class with no abstract methods makes sense, it's entirely up to interpretation and justification. Make the best decision for whatever you're working on.

Tieme put a lot of effort into his excellent answer, but I think the core of the OP's question is how these technologies relate to PHP rather than how each technology works.

PHP is the most used language in web development besides the obvious client side HTML, CSS, and Javascript. Yet PHP has 2 major issues when it comes to real-time applications:

1. PHP started as a very basic CGI. PHP has progressed very far since its early stage, but it happened in small steps. PHP already had many millions of users by the time it became the embed-able and flexible C library that it is today, most of whom were dependent on its earlier model of execution, so it hasn't yet made a solid attempt to escape the CGI model internally. Even the command line interface invokes the PHP library (libphp5.so on Linux, php5ts.dll on Windows, etc) as if it still a CGI processing a GET/POST request. It still executes code as if it just has to build a "page" and then end its life cycle. As a result, it has very little support for multi-thread or event-driven programming (within PHP userspace), making it currently unpractical for real-time, multi-user applications.

Note that PHP does have extensions to provide event loops (such as libevent) and threads (such as pthreads) in PHP userspace, but very, very, few of the applications use these.

2. PHP still has significant issues with garbage collection. Although these issues have been consistently improving (likely its greatest step to end the life cycle as described above), even the best attempts at creating long-running PHP applications require being restarted on a regular basis. This also makes it unpractical for real-time applications.

PHP 7 will be a great step to fix these issues as well, and seems very promising as a platform for real-time applications.

try with removeClass

For instance:

var nameClass=document.getElementsByClassName("clase1");_x000D_
console.log("after", nameClass[0]);_x000D_
$(".clase1").removeClass();_x000D_
var nameClass=document.getElementsByClassName("clase1");_x000D_
console.log("before", nameClass[0]);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div class="clase1">I am Div with class="clase1"</div>

Another option, using the command module:

- name: Create file
  command: touch /path/to/file
  args:
    creates: /path/to/file

The 'creates' argument ensures that this action is not performed if the file exists.

a possible solution could be

create a batch file

there do a loop on lib directory for all files inside it and set each file unside lib on classpath

then after that run the jar

source for loop in batch file for info on loops

If the execution planner says they're the same, they're the same. Use whichever one will make your intention more obvious -- in this case, the second.

As stated in the documentation of Spyder, you need to install PyQt5 first.

Open a Command Prompt as Administrator, then run:

pip install pyqt5
pip install spyder

Then you can find the spyder3.exe in the Python3.6/Scripts folder. You can also make a shortcut to it. No need for Anaconda.

A simple solution but it gets the job done, assigns a known length and precision and avoids the chance of going exponential format (which is a risk when you use %g):

// Since we are only interested in 3 decimal places, this function
// can avoid any potential miniscule floating point differences
// which can return false when using "=="
int DoubleEquals(double i, double j)
{
    return (fabs(i - j) < 0.000001);
}

void PrintMaxThreeDecimal(double d)
{
    if (DoubleEquals(d, floor(d)))
        printf("%.0f", d);
    else if (DoubleEquals(d * 10, floor(d * 10)))
        printf("%.1f", d);
    else if (DoubleEquals(d * 100, floor(d* 100)))
        printf("%.2f", d);
    else
        printf("%.3f", d);
}

Add or remove "elses" if you want a max of 2 decimals; 4 decimals; etc.

For example if you wanted 2 decimals:

void PrintMaxTwoDecimal(double d)
{
    if (DoubleEquals(d, floor(d)))
        printf("%.0f", d);
    else if (DoubleEquals(d * 10, floor(d * 10)))
        printf("%.1f", d);
    else
        printf("%.2f", d);
}

If you want to specify the minimum width to keep fields aligned, increment as necessary, for example:

void PrintAlignedMaxThreeDecimal(double d)
{
    if (DoubleEquals(d, floor(d)))
        printf("%7.0f", d);
    else if (DoubleEquals(d * 10, floor(d * 10)))
        printf("%9.1f", d);
    else if (DoubleEquals(d * 100, floor(d* 100)))
        printf("%10.2f", d);
    else
        printf("%11.3f", d);
}

You could also convert that to a function where you pass the desired width of the field:

void PrintAlignedWidthMaxThreeDecimal(int w, double d)
{
    if (DoubleEquals(d, floor(d)))
        printf("%*.0f", w-4, d);
    else if (DoubleEquals(d * 10, floor(d * 10)))
        printf("%*.1f", w-2, d);
    else if (DoubleEquals(d * 100, floor(d* 100)))
        printf("%*.2f", w-1, d);
    else
        printf("%*.3f", w, d);
}

I had the same problem and found that there was no package.json in my project (but only the package-lock.json). I then

1. restored the package.json from source control
2. uninstalled the global and local angular-cli versions (like the instruction says)
3. followed the standard upgrade procedure

..and all worked out fine. Took a while to figure it out, but that did it for me.

We built a very simple free/opensource component that adds SAML support for ASP.NET apps https://github.com/jitbit/AspNetSaml

Basically it's just one short C# file you can throw into your project (or install via Nuget) and use it with your app

a=[1,2,3]
b=[str(x) for x in a]
print b

above method is the easiest and most general way to convert list into string. another short method is-

a=[1,2,3]
b=map(str,a)
print b
