The server-side processing language in use (eg PHP, .net, etc) isn't specified, but if it's PHP, grab the required number (or all the records) and instead of randomising in the query use PHP's shuffle function. I don't know if .net has an equivalent function but if it does then use that if you're using .net

ORDER BY RAND() can have quite a performance penalty, depending on how many records are involved.

You should try. When you clear your Graphics you must choose color. SystemColors.Control is native color of form

Graphics g = pB.CreateGraphics();
g.Clear(SystemColors.Control);

This might be an old qustion, but just to keep things updated, there is a forEach method in javascript that works with NodeJS. Here's the link from the docs. And an example:

     count = countElements.length;
        if (count > 0) {
            countElements.forEach(function(countElement){
                console.log(countElement);
            });
        }

You can use the following solution to accomplish your goal:

struct student 
{
    char name[20];
    char country[20];
};
void main()
{
    struct student S={"Wolverine","America"};
    struct student X;
    X=S;
    printf("%s%s",X.name,X.country);
}

You may want to try Web Server for Chrome, which serves web pages from a local folder using HTTP. It's simple to use and would avoid the flag, which, as someone mentioned above, might make your file system vulnerable.

A multiline comment doesn't actually exist in Python. The below example consists of an unassigned string, which is validated by Python for syntactical errors.

A few text editors, like Notepad++, provide us shortcuts to comment out a written piece of code or words.

def foo():
    "This is a doc string."
    # A single line comment
    """
       This
       is a multiline
       comment/String
    """
    """
    print "This is a sample foo function"
    print "This function has no arguments"
    """
    return True

Also, Ctrl + K is a shortcut in Notepad++ to block comment. It adds a # in front of every line under the selection. Ctrl + Shift + K is for block uncomment.

you can define a custom ScrollView class, & add an interface be called when scrolling like this:

public class ScrollChangeListenerScrollView extends HorizontalScrollView {


private MyScrollListener mMyScrollListener;

public ScrollChangeListenerScrollView(Context context) {
    super(context);
}

public ScrollChangeListenerScrollView(Context context, AttributeSet attrs) {
    super(context, attrs);
}

public ScrollChangeListenerScrollView(Context context, AttributeSet attrs, int defStyleAttr) {
    super(context, attrs, defStyleAttr);
}


public void setOnMyScrollListener(MyScrollListener myScrollListener){
    this.mMyScrollListener = myScrollListener;
}


@Override
protected void onScrollChanged(int l, int t, int oldl, int oldt) {
    super.onScrollChanged(l, t, oldl, oldt);
    if(mMyScrollListener!=null){
        mMyScrollListener.onScrollChange(this,l,t,oldl,oldt);
    }

}

public interface MyScrollListener {
    void onScrollChange(View view,int scrollX,int scrollY,int oldScrollX, int oldScrollY);
}

}

You need to seed the random number generator, from man 3 rand

If no seed value is provided, the rand() function is automatically seeded with a value of 1.

and

The srand() function sets its argument as the seed for a new sequence of pseudo-random integers to be returned by rand(). These sequences are repeatable by calling srand() with the same seed value.

e.g.

srand(time(NULL));

Here is your solution for the problem,

$letter = array();
for ($i = 'A'; $i !== 'ZZ'; $i++){
        if(ord($i) % 2 != 0)
           $letter[] .= $i;
}
print_r($letter);

You need to get the ASCII value for that character which will solve your problem.

Here is ord doc and working code.

For your requirement, you can do like this,

for ($i = 'A'; $i !== 'ZZ'; ord($i)+$x){
  $letter[] .= $i;
}
print_r($letter);

Here set $x as per your requirement.

You have to retrieve it from the HOST header.

var host = req.get('host');

It is optional with HTTP 1.0, but required by 1.1. And, the app can always impose a requirement of its own.

If this is for supporting cross-origin requests, you would instead use the Origin header.

var origin = req.get('origin');

Note that some cross-origin requests require validation through a "preflight" request:

req.options('/route', function (req, res) {
    var origin = req.get('origin');
    // ...
});

If you're looking for the client's IP, you can retrieve that with:

var userIP = req.socket.remoteAddress;

• message.socket.
• socket.remoteAddress

Note that, if your server is behind a proxy, this will likely give you the proxy's IP. Whether you can get the user's IP depends on what info the proxy passes along. But, it'll typically be in the headers as well.

Is the value of your particular COMMENT column null?

Sometimes NOT LIKE doesn't know how to behave properly around nulls.

The problem is caused by the fact that the Model's toArray() method ignores any accessors which do not directly relate to a column in the underlying table.

As Taylor Otwell mentioned here, "This is intentional and for performance reasons." However there is an easy way to achieve this:

class EventSession extends Eloquent {

    protected $table = 'sessions';
    protected $appends = array('availability');

    public function getAvailabilityAttribute()
    {
        return $this->calculateAvailability();  
    }
}

Any attributes listed in the $appends property will automatically be included in the array or JSON form of the model, provided that you've added the appropriate accessor.

Old answer (for Laravel versions < 4.08):

The best solution that I've found is to override the toArray() method and either explicity set the attribute:

class Book extends Eloquent {

    protected $table = 'books';

    public function toArray()
    {
        $array = parent::toArray();
        $array['upper'] = $this->upper;
        return $array;
    }

    public function getUpperAttribute()
    {
        return strtoupper($this->title);    
    }

}

or, if you have lots of custom accessors, loop through them all and apply them:

class Book extends Eloquent {

    protected $table = 'books';

    public function toArray()
    {
        $array = parent::toArray();
        foreach ($this->getMutatedAttributes() as $key)
        {
            if ( ! array_key_exists($key, $array)) {
                $array[$key] = $this->{$key};   
            }
        }
        return $array;
    }

    public function getUpperAttribute()
    {
        return strtoupper($this->title);    
    }

}

You can change the index as explained already using set_index. You don't need to manually swap rows with columns, there is a transpose (data.T) method in pandas that does it for you:

> df = pd.DataFrame([['ABBOTSFORD', 427000, 448000],
                    ['ABERFELDIE', 534000, 600000]],
                    columns=['Locality', 2005, 2006])

> newdf = df.set_index('Locality').T
> newdf

Locality    ABBOTSFORD  ABERFELDIE
2005        427000      534000
2006        448000      600000

then you can fetch the dataframe column values and transform them to a list:

> newdf['ABBOTSFORD'].values.tolist()

[427000, 448000]

TL;DR: Use StandardError instead for general exception catching. When the original exception is re-raised (e.g. when rescuing to log the exception only), rescuing Exception is probably okay.

Exception is the root of Ruby's exception hierarchy, so when you rescue Exception you rescue from everything, including subclasses such as SyntaxError, LoadError, and Interrupt.

Rescuing Interrupt prevents the user from using CTRLC to exit the program.

Rescuing SignalException prevents the program from responding correctly to signals. It will be unkillable except by kill -9.

Rescuing SyntaxError means that evals that fail will do so silently.

All of these can be shown by running this program, and trying to CTRLC or kill it:

loop do
  begin
    sleep 1
    eval "djsakru3924r9eiuorwju3498 += 5u84fior8u8t4ruyf8ihiure"
  rescue Exception
    puts "I refuse to fail or be stopped!"
  end
end

Rescuing from Exception isn't even the default. Doing

begin
  # iceberg!
rescue
  # lifeboats
end

does not rescue from Exception, it rescues from StandardError. You should generally specify something more specific than the default StandardError, but rescuing from Exception broadens the scope rather than narrowing it, and can have catastrophic results and make bug-hunting extremely difficult.

If you have a situation where you do want to rescue from StandardError and you need a variable with the exception, you can use this form:

begin
  # iceberg!
rescue => e
  # lifeboats
end

which is equivalent to:

begin
  # iceberg!
rescue StandardError => e
  # lifeboats
end

One of the few common cases where it’s sane to rescue from Exception is for logging/reporting purposes, in which case you should immediately re-raise the exception:

begin
  # iceberg?
rescue Exception => e
  # do some logging
  raise # not enough lifeboats ;)
end

right click you project name then open the properties windows. downgrade your Target framework version, build Solution then upgrade your Target framework version to the latest, build Solution .

getopt is your friend.. a simple example:

function f () {
TEMP=`getopt --long -o "u:h:" "$@"`
eval set -- "$TEMP"
while true ; do
    case "$1" in
        -u )
            user=$2
            shift 2
        ;;
        -h )
            host=$2
            shift 2
        ;;
        *)
            break
        ;;
    esac 
done;

echo "user = $user, host = $host"
}

f -u myself -h some_host

There should be various examples in your /usr/bin directory.

Also add the key "StartingMonthColumn" in App.config that you run application from, for example in the App.config of the test project.

I used this import:

import java.util.Date;

And declared my variable like this:

Date studentEnrollementDate;

I think a more flexible option would be to wrap the Text() with Align() like so:

Align(
  alignment: Alignment.center, // Align however you like (i.e .centerRight, centerLeft)
  child: Text("My Text"),
),

Using Center() seems to ignore TextAlign entirely on the Text widget. It will not align TextAlign.left or TextAlign.right if you try, it will remain in the center.

In Python, you don't do things that way. When people do that in languages like Java, they generally want a default value (if they don't, they generally want a method with a different name). So, in Python, you can have default values.

class A(object):  # Remember the ``object`` bit when working in Python 2.x

    def stackoverflow(self, i=None):
        if i is None:
            print 'first form'
        else:
            print 'second form'

As you can see, you can use this to trigger separate behaviour rather than merely having a default value.

>>> ob = A()
>>> ob.stackoverflow()
first form
>>> ob.stackoverflow(2)
second form

Nobody's mentioned logging yet, but logging was created specifically to communicate error messages. Basic configuration will set up a stream handler writing to stderr.

This script:

# foo.py
import logging

logging.basicConfig(format='%(message)s')
log = logging.getLogger(__name__)
log.warning('I print to stderr by default')
print('hello world')

has the following result when run on the command line:

$ python3 foo.py > bar.txt
I print to stderr by default

and bar.txt will contain the 'hello world' printed on stdout.

After several attempts and going deep in Tomcat's source code I found out that the simple property useNaming="false" did the trick!! Now Tomcat resolves names java:/liferay instead of java:comp/env/liferay

Have you gone through google's geocoding api. The following link shall help you get started: http://code.google.com/apis/maps/documentation/geocoding/#GeocodingRequests

Taking a guess at the results you want so maybe this is the query you want then

SELECT DISTINCT a FROM my_table
UNION 
SELECT DISTINCT b FROM my_table
UNION
SELECT DISTINCT c FROM my_table
UNION
SELECT DISTINCT d FROM my_table

I force reload my component using *ngIf.

All the components inside my container goes back to the full lifecycle hooks .

In the template :

<ng-container *ngIf="_reload">
    components here 
</ng-container>

Then in the ts file :

public _reload = true;

private reload() {
    setTimeout(() => this._reload = false);
    setTimeout(() => this._reload = true);
}

one way to accomplish this to have a server side application that waits for the data. The data can be sent using HttpRequest objects in Java or you can write your own TCP/IP data transfer utility. Data can be sent using JSON format or any other format that you think is suitable. Also data can be encrypted before sending to server if it contains sensitive information. All Server application have to do is just wait for HttpRequests to come in and parse the data and store it anywhere you want.

A Simple solution :

Create a drawable file as edittext_stroke.xml in drawable folder. Add the below code:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="line"
   >
    <stroke
        android:width="1dp"
        android:color="@android:color/white" >
    </stroke>
</shape>

In layout file , add the drawable to edittext as

android:drawableBottom="@drawable/edittext_stroke"

<EditText
      android:textColor="@android:color/white"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:drawableBottom="@drawable/edittext_stroke"
      />

You should use open with the w+ mode:

file = open('myfile.dat', 'w+')

After Struggling a bit with Arzoo International flight API, I've finally found the solution and the code simply works absolutely great with me. Here are the complete working code:

//Store your XML Request in a variable
    $input_xml = '<AvailRequest>
            <Trip>ONE</Trip>
            <Origin>BOM</Origin>
            <Destination>JFK</Destination>
            <DepartDate>2013-09-15</DepartDate>
            <ReturnDate>2013-09-16</ReturnDate>
            <AdultPax>1</AdultPax>
            <ChildPax>0</ChildPax>
            <InfantPax>0</InfantPax>
            <Currency>INR</Currency>
            <PreferredClass>E</PreferredClass>
            <Eticket>true</Eticket>
            <Clientid>777ClientID</Clientid>
            <Clientpassword>*Your API Password</Clientpassword>
            <Clienttype>ArzooINTLWS1.0</Clienttype>
            <PreferredAirline></PreferredAirline>
    </AvailRequest>';

Now I've made a little changes in the above curl_setopt declaration as follows:

    $url = "http://59.162.33.102:9301/Avalability";

        //setting the curl parameters.
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
// Following line is compulsary to add as it is:
        curl_setopt($ch, CURLOPT_POSTFIELDS,
                    "xmlRequest=" . $input_xml);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 300);
        $data = curl_exec($ch);
        curl_close($ch);

        //convert the XML result into array
        $array_data = json_decode(json_encode(simplexml_load_string($data)), true);

        print_r('<pre>');
        print_r($array_data);
        print_r('</pre>');

That's it the code works absolutely fine for me. I really appreciate @hakre & @Lucas For their wonderful support.

Since both projects are under the same solution, there's a simpler way for the include files and linker as described in https://docs.microsoft.com/en-us/cpp/build/adding-references-in-visual-cpp-projects?view=vs-2019 :

1. The include can be written in a relative path (E.g. #include "../libProject/libHeader.h").
2. For the linker, right click on "References", Click on Add Reference, and choose the other project.

Nick's solutuion can be simplified more, with nothing fancy, you would only need a single converter:

[ValueConversion(typeof(Enum), typeof(IEnumerable<Enum>))]
public class EnumToCollectionConverter : MarkupExtension, IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        var r = Enum.GetValues(value.GetType());
        return r;
    }
    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
        return null;
    }
    public override object ProvideValue(IServiceProvider serviceProvider)
    {
        return this;
    }
}

You then use this wherever you want your combo box to appear:

<ComboBox ItemsSource="{Binding PagePosition, Converter={converter:EnumToCollectionConverter}, Mode=OneTime}"  SelectedItem="{Binding PagePosition}" />

A BLOB can be 65535 bytes (64 KB) maximum.

If you need more consider using:

• a MEDIUMBLOB for 16777215 bytes (16 MB)

• a LONGBLOB for 4294967295 bytes (4 GB).

I've tried a select statement now with a PreparedStatement, but it turned out that it was not faster than the Jdbc template. Maybe, as mezmo suggested, it automatically creates prepared statements.

Anyway, the reason for my sql SELECTs being so slow was another one. In the WHERE clause I always used the operator LIKE, when all I wanted to do was finding an exact match. As I've found out LIKE searches for a pattern and therefore is pretty slow.

I'm using the operator = now and it's much faster.

System is a final class from the java.lang package.

out is a class variable of type PrintStream declared in the System class.

println is a method of the PrintStream class.

from Queue API:

The offer method inserts an element if possible, otherwise returning false. This differs from the Collection.add method, which can fail to add an element only by throwing an unchecked exception. The offer method is designed for use when failure is a normal, rather than exceptional occurrence, for example, in fixed-capacity (or "bounded") queues.

If you want to use SelectedValue then your combobox must be databound.

To set up the combobox:

ComboBox1.DataSource = GetMailItems()
ComboBox1.DisplayMember = "Name"
ComboBox1.ValueMember = "ID"

To get the data:

Function GetMailItems() As List(Of MailItem)

    Dim mailItems = New List(Of MailItem)

    Command = New MySqlCommand("SELECT * FROM `maillist` WHERE l_id = '" & id & "'", connection)
    Command.CommandTimeout = 30
    Reader = Command.ExecuteReader()

    If Reader.HasRows = True Then
        While Reader.Read()
            mailItems.Add(New MailItem(Reader("ID"), Reader("name")))
        End While
    End If

    Return mailItems

End Function

Public Class MailItem

    Public Sub New(ByVal id As Integer, ByVal name As String)
        mID = id
        mName = name
    End Sub

    Private mID As Integer
    Public Property ID() As Integer
        Get
            Return mID
        End Get
        Set(ByVal value As Integer)
            mID = value
        End Set
    End Property

    Private mName As String
    Public Property Name() As String
        Get
            Return mName
        End Get
        Set(ByVal value As String)
            mName = value
        End Set
    End Property

End Class

Here is a pure css solution using viewport units and variables that automatically scales to the device (and works on window resize). I added the following to Alex's solution:

        html,body {
            width: 100%;
            height: 100%;
            position: fixed;/* prevents scrolling */
            --innerheight: 100vh;/* variable 100% of viewport height */
        }

        body {
            overflow: hidden; /* prevents scrolling */
        }

        .panel {
            width: 100%;
            height: var(--innerheight); /* viewport height */

        a[ id= "galeria" ]:target ~ #main article.panel {
            -webkit-transform: translateY( calc(-1*var(--innerheight)) );
            transform: translateY( calc(-1*var(--innerheight)) );
        }

        a[ id= "contacto" ]:target ~ #main article.panel {
            -webkit-transform: translateY( calc(-2*var(--innerheight)) );
            transform: translateY( calc(-2*var(--innerheight)) );

All of this works for me:

@Echo Off
Echo Directory = %~dp0
Echo Object Name With Quotations=%0
Echo Object Name Without Quotes=%~0
Echo Bat File Drive = %~d0
Echo Full File Name = %~n0%~x0

I just encountered the issue and couldn't figure out what was going wrong even after reading all the above and everything out there. What I did was

1. Set root logger level to WARN
   
2. Set package log level to DEBUG
   

Each logging implementation has it's own way of setting it via properties or via code(lot of help available on this)

Irrespective of all the above I would not get the logs in my console or my log file. What I had overlooked was the below...

All I was doing with the above jugglery was controlling only the production of the logs(at root/package/class etc), left of the red line in above image. But I was not changing the way displaying/consumption of the logs of the same, right of the red line in above image. Handler(Consumption) is usually defaulted at INFO, therefore your precious debug statements wouldn't come through. Consumption/displaying is controlled by setting the log levels for the Handlers(ConsoleHandler/FileHandler etc..) So I went ahead and set the log levels of all my handlers to finest and everything worked.

This point was not made clear in a precise manner in any place.

I hope someone scratching their head, thinking why the properties are not working will find this bit helpful.

Using @joran's sample data,

ggplot(dat, aes(x=xx, fill=yy)) + geom_histogram(alpha=0.2, position="identity")

note that the default position of geom_histogram is "stack."

see "position adjustment" of this page:

docs.ggplot2.org/current/geom_histogram.html

why dont you add a "source" column to each of the queries with a static value like

select 'source 1' as Source, column1, column2...
from table1

UNION ALL

select 'source 2' as Source, column1, column2...
from table2

Instead of using array you can use the ArrayList directly and can use the contains method to check the value which u have passes with the ArrayList.

$url = " www.domain.com/car/audi/";
if (strpos($url, "car")!==false){
    echo "Car here";
}
else {
   echo "No car here :(";
}

See strpos manual

You can install from nuget as the the below image:

Or, run the below command line on Package Manager Console:

Install-Package Microsoft.AspNet.WebApi

I encountered this issue when using a different AWS profile. I saw the error when I was using an account with admin permissions, so the possibility of permissions issues seemed unlikely.

It's really a pet peeve of mine that AWS is so prone to issuing error messages that have such little correlation with the required actions, from a user perspective.

Try this:

The answer by Agalin is already great and I just want to explain it in a step by step format for a novice like myself:

• find your Python version by python --version mine is 3.7.3 for example
• the easiest way to check either you have 64 or 32 Python just open it in the terminal:

• find the appropriate .whl file from here, for example mine is PyAudio-0.2.11-cp37-cp37m-win_amd64.whl, and download it.
• go to the folder where it is downloaded for example cd C:\Users\foobar\Downloads
• install the .whl file with pip for example in my case:

pip install PyAudio-0.2.11-cp37-cp37m-win_amd64.whl

I know this is a pretty old question but this was my solution that helped with visualizing the table so you can create a class structure. This is also using the HTML Agility Pack

HtmlDocument doc = new HtmlDocument();
doc.LoadHtml(@"<html><body><p><table id=""foo""><tr><th>hello</th></tr><tr><td>world</td></tr></table></body></html>");
var table = doc.DocumentNode.SelectSingleNode("//table");
var tableRows = table.SelectNodes("tr");
var columns = tableRows[0].SelectNodes("th/text()");
for (int i = 1; i < tableRows.Count; i++)
{
    for (int e = 0; e < columns.Count; e++)
    {
        var value = tableRows[i].SelectSingleNode($"td[{e + 1}]");
        Console.Write(columns[e].InnerText + ":" + value.InnerText);
    }
Console.WriteLine();
}

You could use Linq's FirstOrDefault extension method:

string element = myList.FirstOrDefault(s => s.Contains(myString));

This will return the fist element that contains the substring myString, or null if no such element is found.

If all you need is the index, use the List<T> class's FindIndex method:

int index = myList.FindIndex(s => s.Contains(myString));

This will return the the index of fist element that contains the substring myString, or -1 if no such element is found.

Delete the row from the table dtPrf_Mstr rather than from the grid view.

The jQuery DataTables plug-in is one excellent way to achieve excel-like fixed column(s) and headers.

Note the examples section of the site and the "extras".
http://datatables.net/examples/
http://datatables.net/extras/

The "Extras" section has tools for fixed columns and fixed headers.

Fixed Columns

You don't want git revert. That undoes a previous commit. You want git checkout to get git's version of the file from master.

git checkout -- filename.txt

In general, when you want to perform a git operation on a single file, use -- filename.

• git-checkout Documentation
• git-revert Documentation

2020 Update

Git introduced a new command git restore in version 2.23.0. Therefore, if you have git version 2.23.0+, you can simply git restore filename.txt - which does the same thing as git checkout -- filename.txt. The docs for this command do note that it is currently experimental.

You can try this code .

private enum DownloadType {
    AUDIO , VIDEO , AUDIO_AND_VIDEO ;

}

You can use this enumeration as like this : DownloadType.AUDIO.ordinal(). Hope this code snippet will help you .

Another library is 4Suite: http://sourceforge.net/projects/foursuite/

I do not know how spec-compliant it is. But it has worked very well for my use. It looks abandoned.

with momentjs i use

moment(value).format("YYYY-MM-DDTHH:mm:ss")

Solution who works with Lumen 5.5 with foreign keys constraints :

$categories = MusicCategory::all();
foreach($categories as $category)
{
$category->delete();

}
return response()->json(['error' => false]);

A couple short, sweet extension methods on IEnumerable and IEnumerable<T> do it for me:

public static IEnumerable Append(this IEnumerable first, params object[] second)
{
    return first.OfType<object>().Concat(second);
}
public static IEnumerable<T> Append<T>(this IEnumerable<T> first, params T[] second)
{
    return first.Concat(second);
}   
public static IEnumerable Prepend(this IEnumerable first, params object[] second)
{
    return second.Concat(first.OfType<object>());
}
public static IEnumerable<T> Prepend<T>(this IEnumerable<T> first, params T[] second)
{
    return second.Concat(first);
}

Elegant (well, except for the non-generic versions). Too bad these methods are not in the BCL.

On Linux and macOS you can run simple command to the shell:

subprocess.run('rm /tmp/*.bak', shell=True)

you should just be able to call it by typing in the file name. You may have to call ./a.exe as the current directory is usually not on the path for security reasons.

In my case, basically I needed to restart my Windows.

function copyToClipboard(text) {
    var dummy = document.createElement("textarea");
    // to avoid breaking orgain page when copying more words
    // cant copy when adding below this code
    // dummy.style.display = 'none'
    document.body.appendChild(dummy);
    //Be careful if you use texarea. setAttribute('value', value), which works with "input" does not work with "textarea". – Eduard
    dummy.value = text;
    dummy.select();
    document.execCommand("copy");
    document.body.removeChild(dummy);
}
copyToClipboard('hello world')
copyToClipboard('hello\nworld')

If you use this:

body {
    overflow: overlay;
}

The scrollbar will then also take transparent backgrounds across the page. This will also put the scrollbar inside the page instead of removing some of the width to put in the scrollbar.

Here is a demo code. I wasn't able to put it inside any of the codepen or jsfiddle, apperantly it took me a while until I figured out, but they don't show the transparency, and I don't know why.

But putting this in a HTML file should go fine.

Was able to put it on fiddle: https://jsfiddle.net/3awLgj5v/

Best way to test it is to create a local html file, I guess.

You can also apply that on other elements, such as any scrolling box. While using inspector mode, it could be that you have to put the overflow to hidden and then back to anything else. It probably needed to refresh. After that it should be possible working on scrollbar without having to refresh it again. Just note that was for the inspector mode.

The answers provided by Bohzo and Brabster will obviously work, but you could also just use:

rs3.getInt(1);

to get the value in the first, and in your case, only column.

• In terms of speed: #1 and #4, but not by much in most instances.

  You could write a benchmark to confirm, but I suspect you'll find #1 and #4 to be slightly faster because the iteration work is done in C instead of Perl, and no needless copying of the array elements occurs. ($_ is aliased to the element in #1, but #2 and #3 actually copy the scalars from the array.)

  #5 might be similar.

• In terms memory usage: They're all the same except for #5.

  for (@a) is special-cased to avoid flattening the array. The loop iterates over the indexes of the array.

• In terms of readability: #1.

• In terms of flexibility: #1/#4 and #5.

  #2 does not support elements that are false. #2 and #3 are destructive.

Jackson

If you are using Jackson, then you can use the @JsonProperty annotation to customize the name of a given JSON property.

Therefore, you just have to annotate the entity fields with the @JsonProperty annotation and provide a custom JSON property name, like this:

@Entity
public class City {

   @Id
   @JsonProperty("value")
   private Long id;

   @JsonProperty("label")
   private String name;

   //Getters and setters omitted for brevity
}

JavaEE or JakartaEE JSON-B

JSON-B is the standard binding layer for converting Java objects to and from JSON. If you are using JSON-B, then you can override the JSON property name via the @JsonbProperty annotation:

@Entity
public class City {

   @Id
   @JsonbProperty("value")
   private Long id;

   @JsonbProperty("label")
   private String name;

   //Getters and setters omitted for brevity
}

$('.IsBestAnswer').removeClass('IsBestAnswer').addClass('bestanswer');

Your code has two problems:

1. The selector .IsBestAnswe does not match what you thought
2. It's addClass(), not addclass().

Also, I'm not sure whether you want to replace the class or add it. The above will replace, but remove the .removeClass('IsBestAnswer') part to add only:

$('.IsBestAnswer').addClass('bestanswer');

You should decide whether to use camelCase or all-lowercase in your CSS classes too (e.g. bestAnswer vs. bestanswer).

Another veneration of find_elements_by_xpath(".//*") is:

from selenium.webdriver.common.by import By


find_elements(By.XPATH, ".//*")

Building on @tmullaney 's answer, you can also left join in the sys.objects view to get insight when explicit permissions have been granted on objects. Make sure to use the LEFT join:

SELECT DISTINCT pr.principal_id, pr.name AS [UserName], pr.type_desc AS [User_or_Role], pr.authentication_type_desc AS [Auth_Type], pe.state_desc,
    pe.permission_name, pe.class_desc, o.[name] AS 'Object' 
    FROM sys.database_principals AS pr 
    JOIN sys.database_permissions AS pe ON pe.grantee_principal_id = pr.principal_id
    LEFT JOIN sys.objects AS o on (o.object_id = pe.major_id)

use this after initialisation

$('.form_datetime').datetimepicker('update', new Date());

to work this with unicode or fontawesome, you should add a span with class like below, because input tag not support pseudo classes like :after. this is not a direct solution

in html:

   <span class="button1 search"></span>
<input name="username">

in css:

.button1 {
    background-color: #B9D5AD;
    border-radius: 0.2em 0 0 0.2em;
    box-shadow: 1px 0 0 rgba(0, 0, 0, 0.5), 2px 0 0 rgba(255, 255, 255, 0.5); 
    pointer-events: none;
    margin:1px 12px;    
    border-radius: 0.2em;    
    color: #333333;
    cursor: pointer;
    position: absolute;
    padding: 3px;
    text-decoration: none;   

}

Try it:

#!/usr/bin/python

import gtk.gdk
import time

import socket
import fcntl
import struct
import getpass
import os
import paramiko     

while 1:
    # generate a random time between 120 and 300 sec
    random_time = random.randrange(20,25)
    # wait between 120 and 300 seconds (or between 2 and 5 minutes) 

    print "Next picture in: %.2f minutes" % (float(random_time) / 60)

    time.sleep(random_time)
    w = gtk.gdk.get_default_root_window()   
    sz = w.get_size()
    print "The size of the window is %d x %d" % sz
    pb = gtk.gdk.Pixbuf(gtk.gdk.COLORSPACE_RGB,False,8,sz[0],sz[1])
    pb = pb.get_from_drawable(w,w.get_colormap(),0,0,0,0,sz[0],sz[1])
    ts = time.asctime( time.localtime(time.time()) )
    date = time.strftime("%d-%m-%Y")
    timer = time.strftime("%I:%M:%S%p")
    filename = timer
    filename += ".png"

    if (pb != None):
        username = getpass.getuser() #Get username
        newpath = r'screenshots/'+username+'/'+date #screenshot save path
        if not os.path.exists(newpath): os.makedirs(newpath)
        saveas = os.path.join(newpath,filename)
        print saveas
        pb.save(saveas,"png")
    else:
        print "Unable to get the screenshot."

Executable file needs a main function. See below hello world demo.

#include <stdio.h>
int main(void)
{
        printf("Hello world!\n");
        return 0;
}

As you can see there is a main function. if you don't have this main function, ld will report "undefined reference to main' "

check my result:

$ cat es3.c
#include <stdio.h>
int main(void)
{
    printf("Hello world!\n");
    return 0;
}
$ gcc -Wall -g -c es3.c
$ gcc -Wall -g es3.o -o es3
~$ ./es3
Hello world! 

please use $ objdump -t es3.o to check if there is a main symbol. Below is my result.

$ objdump -t es3.o

es3.o:     file format elf32-i386

00000000 g     F .text  0000002b main
00000000         *UND*  00000000 puts

Simply:

.grow { transition: all .2s ease-in-out; }

This will allow the element to assign an animation via css.

.grow:hover { transform: scale(1.1); }

This will make it grow!

First you need to select an implementation library to do that.

The Java API for JSON Processing (JSR 353) provides portable APIs to parse, generate, transform, and query JSON using object model and streaming APIs.

The reference implementation is here: https://jsonp.java.net/

Here you can find a list of implementations of JSR 353:

What are the API that does implement JSR-353 (JSON)

And to help you decide... I found this article as well:

http://blog.takipi.com/the-ultimate-json-library-json-simple-vs-gson-vs-jackson-vs-json/

If you go for Jackson, here is a good article about conversion between JSON to/from Java using Jackson: https://www.mkyong.com/java/how-to-convert-java-object-to-from-json-jackson/

Hope it helps!

Specification

In the SVG specification version 1.1 the rendering order is based on the document order:

first element -> "painted" first

Reference to the SVG 1.1. Specification

3.3 Rendering Order

Elements in an SVG document fragment have an implicit drawing order, with the first elements in the SVG document fragment getting "painted" first. Subsequent elements are painted on top of previously painted elements.

Solution (cleaner-faster)

You should put the green circle as the latest object to be drawn. So swap the two elements.

<svg xmlns="http://www.w3.org/2000/svg" viewBox="30 70 160 120"> _x000D_
   <!-- First draw the orange circle -->_x000D_
   <circle fill="orange" cx="100" cy="95" r="20"/> _x000D_
_x000D_
   <!-- Then draw the green circle over the current canvas -->_x000D_
   <circle fill="green" cx="100" cy="105" r="20"/> _x000D_
</svg>

Here the fork of your jsFiddle.

Solution (alternative)

The tag use with the attribute xlink:href and as value the id of the element. Keep in mind that might not be the best solution even if the result seems fine. Having a bit of time, here the link of the specification SVG 1.1 "use" Element.

Purpose:

To avoid requiring authors to modify the referenced document to add an ID to the root element.

<svg xmlns="http://www.w3.org/2000/svg" viewBox="30 70 160 120">_x000D_
    <!-- First draw the green circle -->_x000D_
    <circle id="one" fill="green" cx="100" cy="105" r="20" />_x000D_
    _x000D_
    <!-- Then draw the orange circle over the current canvas -->_x000D_
    <circle id="two" fill="orange" cx="100" cy="95" r="20" />_x000D_
    _x000D_
    <!-- Finally draw again the green circle over the current canvas -->_x000D_
    <use xlink:href="#one"/>_x000D_
</svg>

Notes on SVG 2

SVG 2 Specification is the next major release and still supports the above features.

3.4. Rendering order

Elements in SVG are positioned in three dimensions. In addition to their position on the x and y axis of the SVG viewport, SVG elements are also positioned on the z axis. The position on the z-axis defines the order that they are painted.

Along the z axis, elements are grouped into stacking contexts.

3.4.1. Establishing a stacking context in SVG

...

Stacking contexts are conceptual tools used to describe the order in which elements must be painted one on top of the other when the document is rendered, ...

You're looking for:

.is(':visible')

Although you should probably change your selector to use jQuery considering you're using it in other places anyway:

if($('#testElement').is(':visible')) {
    // Code
}

It is important to note that if any one of a target element's parent elements are hidden, then .is(':visible') on the child will return false (which makes sense).

jQuery 3

:visible has had a reputation for being quite a slow selector as it has to traverse up the DOM tree inspecting a bunch of elements. There's good news for jQuery 3, however, as this post explains (Ctrl + F for :visible):

Thanks to some detective work by Paul Irish at Google, we identified some cases where we could skip a bunch of extra work when custom selectors like :visible are used many times in the same document. That particular case is up to 17 times faster now!

Keep in mind that even with this improvement, selectors like :visible and :hidden can be expensive because they depend on the browser to determine whether elements are actually displaying on the page. That may require, in the worst case, a complete recalculation of CSS styles and page layout! While we don’t discourage their use in most cases, we recommend testing your pages to determine if these selectors are causing performance issues.

Expanding even further to your specific use case, there is a built in jQuery function called $.fadeToggle():

function toggleTestElement() {
    $('#testElement').fadeToggle('fast');
}

You may try this one

    $this->db->where('field1',$filed1);
    $this->db->where('filed2',$filed2);
    $result = $this->db->get('table_name')->num_rows();

%Lf (note the capital L) is the format specifier for long doubles.

For plain doubles, either %e, %E, %f, %g or %G will do.

This can be done with MySQL, although it's highly unintuitive:

CREATE PROCEDURE p25 (OUT return_val INT)
BEGIN
  DECLARE a,b INT;
  DECLARE cur_1 CURSOR FOR SELECT s1 FROM t;
  DECLARE CONTINUE HANDLER FOR NOT FOUND
  SET b = 1;
  OPEN cur_1;
  REPEAT
    FETCH cur_1 INTO a;
    UNTIL b = 1
  END REPEAT;
  CLOSE cur_1;
  SET return_val = a;
END;//

Angular 2, 4 and Angular 5 compatible!

You have provided so few details, so I'll try to answer your question without them.

You can use Interpolation:

<img src={{imagePath}} />

Or you can use a template expression:

<img [src]="imagePath" />

In a ngFor loop it might look like this:

<div *ngFor="let student of students">
   <img src={{student.ImagePath}} />
</div>

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

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

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

Because your else isn't attached to anything. The if without braces only encompasses the single statement that immediately follows it.

if (choice==5)
{
    System.out.println("End of Game\n Thank you for playing with us!");
    break;
}
else
{
   System.out.println("Not a valid choice!\n Please try again...\n");
}

Not using braces is generally viewed as a bad practice because it can lead to the exact problems you encountered.

In addition, using a switch here would make more sense.

int choice;
boolean keepGoing = true;
while(keepGoing)
{
    System.out.println("---> Your choice: ");
    choice = input.nextInt();
    switch(choice)
    {
        case 1: 
            playGame();
            break;
        case 2: 
            loadGame();
            break;
        // your other cases
        // ...
        case 5: 
            System.out.println("End of Game\n Thank you for playing with us!");
            keepGoing = false;
            break;
        default:
            System.out.println("Not a valid choice!\n Please try again...\n");
     }
 }         

Note that instead of an infinite for loop I used a while(boolean), making it easy to exit the loop. Another approach would be using break with labels.

For me was php version from mac instead of MAMP, PATH variable on .bash_profile was wrong. I just prepend the MAMP PHP bin folder to the $PATH env variable. For me was:

/Applications/mampstack-7.1.21-0/php/bin

1. In terminal run vim ~/.bash_profile to open ~/.bash_profile

2. Type i to be able to edit the file, add the bin directory as PATH variable on the top to the file:

   export PATH="/Applications/mampstack-7.1.21-0/php/bin/:$PATH"

You need to use the Scatter chart type instead of Line. That will allow you to define separate X values for each series.

Check out this SO question's accepted solution. Substitute your own filename for basename($File) and change filesize($File) to strlen($your_string). (You may want to use mb_strlen just in case the string contains multibyte characters.)

Java's Calendar representation is not the best, they are working on it for Java 8. I would advise you to use Joda Time or another similar library.

Here is a quick example using LocalDate from the Joda Time library:

LocalDate localDate = new LocalDate(year, month, day);
Date date = localDate.toDate();

Here you can follow a quick start tutorial.

Find your location in the Google Earth program, and click the icon "View in Google Maps". The URL bar in your browser will show the URL you need.

Darren Davies is partially correct in saying that you should use a salt - there are several issues with his claim that MD5 is insecure.

You've said that you have to insert the password using an Md5 hash, but that doesn't really tell us why. Is it because that's the format used when validatinb the password? Do you have control over the code which validates the password?

The thing about using a salt is that it avoids the problem where 2 users have the same password - they'll also have the same hash - not a desirable outcome. By using a diferent salt for each password then this does not arise (with very large volumes of data there is still a risk of collisions arising from 2 different passwords - but we'll ignore that for now).

So you can aither generate a random value for the salt and store that in the record too, or you could use some of the data you already hold - such as the username:

$query="INSERT INTO ptb_users (id,
        user_id,
        first_name,
        last_name,
        email )
        VALUES('NULL',
        'NULL',
        '".$firstname."',
        '".$lastname."',
        '".$email."',
        MD5('"$user_id.$password."')
        )";

(I am assuming that you've properly escaped all those strings earlier in your code)

You could also try putting your code in the Activated event of the form, if you want it to occur, just when the form is activated. You would need to put in a boolean "has executed" check though if it is only supposed to run on the first activation.

Just for fun:

return myString.SequenceEqual(myString.Reverse());

There are 2 solutions mentioned below:

Solution 1

MySQL is most likely in STRICT SQL mode. Try to execute SQL query SET GLOBAL sql_mode='' or edit your my.cnf / my.ini to make sure you aren't setting STRICT_ALL_TABLES and/or STRICT_TRANS_TABLES.

Solution 2

If Solution-1 is not working then try Solution-2 as given in below steps:

1. Run MySQL Administrator tool as Administrator.
2. Then go to Startup Variable.
3. Then go to the Advance tab.
4. find SQL Mode and remove the STRICT_ALL_TABLES and/or STRICT_TRANS_TABLES and then Click on Apply Changes.
5. Restart MySQL Server.
6. Done.

Note: I have tested these solutions in MySQL Server 5.7

In C++ a class with at least one pure virtual function is called abstract class. You can not create objects of that class, but may only have pointers or references to it.

If you are deriving from an abstract class, then make sure you override and define all pure virtual functions for your class.

From your snippet Your class AliceUniversity seems to be an abstract class. It needs to override and define all the pure virtual functions of the classes Graduate and UniversityGraduate.

Pure virtual functions are the ones with = 0; at the end of declaration.

Example: virtual void doSomething() = 0;

For a specific answer, you will need to post the definition of the class for which you get the error and the classes from which that class is deriving.

I'm a beginner, but I had that problem while playing around with the "Hello Grid View". I was trying to use my own photos, which were all very large in file size.

The quick fix was to reduce the number of photos, thus reducing the size of the APK file.

But, I guess my follow up question for anybody else who hits this thread is this: How do I attach large files like JPGs and MP3s to an app and make sure they save on the SD Card so the APK remains small?

There is a command line program to convert any Java project into a SBT/Maven project.

It resolves all jars and tries to figure out the correct version based on SHA checksum, classpath or filename. Then it tries to compile the sources until it finds a working configuration. Custom tasks to execute per dependency configuration can be given too.

@Matanya - have you looked at your server logs to see WHAT the error 500 actually is? It could be any number of things

@Aladin - white screen of death (WSOD) can be diagnosed in three ways with Laravel 4.

Option 1: Go to your Laravel logs (app/storage/logs) and see if the error is contained in there.

Option 2: Go to you PHP server logs, and look for the PHP error that is causing the WSOD

Option 3: Good old debugging skills - add a die('hello') command at the start of your routes file - then keep moving it deeper and deeper into your application until you no longer see the 'hello' message. Using this you will be able to narrow down the line that is causing your WSOD and fix the problem.

You can try this

String text = "ddd123.0114cc";
    String numOnly = text.replaceAll("\\p{Alpha}","");
    try {
        double numVal = Double.valueOf(numOnly);
        System.out.println(text +" contains numbers");
    } catch (NumberFormatException e){
        System.out.println(text+" not contains numbers");
    }     

Use this.

{
  /your/first/command
  /your/second/command
} &> /dev/null

Explanation

To eliminate output from commands, you have two options:

• Close the output descriptor file, which keeps it from accepting any more input. That looks like this:

  your_command "Is anybody listening?" >&-
  

  Usually, output goes either to file descriptor 1 (stdout) or 2 (stderr). If you close a file descriptor, you'll have to do so for every numbered descriptor, as &> (below) is a special BASH syntax incompatible with >&-:

  /your/first/command >&- 2>&-
  

  Be careful to note the order: >&- closes stdout, which is what you want to do; &>- redirects stdout and stderr to a file named - (hyphen), which is not what what you want to do. It'll look the same at first, but the latter creates a stray file in your working directory. It's easy to remember: >&2 redirects stdout to descriptor 2 (stderr), >&3 redirects stdout to descriptor 3, and >&- redirects stdout to a dead end (i.e. it closes stdout).

  Also beware that some commands may not handle a closed file descriptor particularly well ("write error: Bad file descriptor"), which is why the better solution may be to...

• Redirect output to /dev/null, which accepts all output and does nothing with it. It looks like this:

  your_command "Hello?" > /dev/null
  

  For output redirection to a file, you can direct both stdout and stderr to the same place very concisely, but only in bash:

  /your/first/command &> /dev/null
  

Finally, to do the same for a number of commands at once, surround the whole thing in curly braces. Bash treats this as a group of commands, aggregating the output file descriptors so you can redirect all at once. If you're familiar instead with subshells using ( command1; command2; ) syntax, you'll find the braces behave almost exactly the same way, except that unless you involve them in a pipe the braces will not create a subshell and thus will allow you to set variables inside.

{
  /your/first/command
  /your/second/command
} &> /dev/null

See the bash manual on redirections for more details, options, and syntax.

Image.onload() will often work.

To use it, you'll need to be sure to bind the event handler before you set the src attribute.

This answer is now obsolete! GitHub will forward to new locations now. See this answer for details.

The reason this warning is there is because #1 can't be made manually.

If you are the only person working on and linking to the repository, then you are fine with changing the remote in your local repo and in your webpages.

However, the reason to have a public repository on github in the first place is that you can have others cloning your repository and linking to your github project page.

The old url github.com/<username>/<repository> is owned by github. When they don't setup any redirects to the new url, nobody can. So things will break for everybody except the persons you are telling.

How big of a problem that is, is up to you though. If you have an official project page on a different server, then the github url might not be much of a problem. If you advertised your project with the github url in mailing lists and directories, then you probably should not change the repo name.

An alternative to changing the repo name is to create a new repository and leave notes in the old one (also as commits in the repo) about how to reach your new repo.

If you wan't your new repo to be listed as a fork of your old repo you need to create a new github account. You can add your other account as a collaborator for both repositories.

In January 2004, I was contacted by Philips New Display Technologies who were creating the electronics for the first ever commercial e-ink, the Sony Librie, who had only been released in Japan, years before Amazon Kindle and the others hit the market in US an Europe.

The Philips engineers had a major problem. A few months before the product was supposed to hit the market, they were still getting ghosting on the screen when changing pages. The problem was the 200 drivers that were creating the electrostatic field. Each of these drivers had a certain voltage that had to be set right between zero and 1000 mV or something like this. But if you changed one of them, it would change everything.

So optimizing each driver's voltage individually was out of the question. The number of possible combination of values was in billions,and it took about 1 minute for a special camera to evaluate a single combination. The engineers had tried many standard optimization techniques, but nothing would come close.

The head engineer contacted me because I had previously released a Genetic Programming library to the open-source community. He asked if GP/GA's would help and if I could get involved. I did, and for about a month we worked together, me writing and tuning the GA library, on synthetic data, and him integrating it into their system. Then, one weekend they let it run live with the real thing.

The following Monday I got these glowing emails from him and their hardware designer, about how nobody could believe the amazing results the GA found. This was it. Later that year the product hit the market.

I didn't get paid one cent for it, but I got 'bragging' rights. They said from the beginning they were already over budget, so I knew what the deal was before I started working on it. And it's a great story for applications of GAs. :)

It's almost always safer to use a library like lodash simply because of all the issues with cross-browser compatibilities and efficiency.

Efficiency because you can be guaranteed that at any given time, a hugely popular library like underscore will have the most efficient method of accomplishing a utility function like this.

_.includes([1, 2, 3], 3); // returns true

If you're concerned about the bulk that's being added to your application by including the whole library, know that you can include functionality separately:

var includes = require('lodash/collections/includes');

NOTICE: With older versions of lodash, this was _.contains() rather than _.includes().

Got a similar error from CircleCi's error log.

"ERROR in The Angular Compiler requires TypeScript >=3.1.1 and <3.3.0 but 3.3.3333 was found instead."

Just so you know this did not affect the Angular application, but the CircleCi error was becoming annoying. I am running Angular 7.1

I ran: $ npm i [email protected] --save-dev --save-exact to update the package-lock.json file.

Then I ran: $ npm i

After that I ran: $ npm audit fix

"This CircleCi error message" went away. So it works

Angular 8 & rxjs 6 in 2019 version

I would like to share the solution based on others great solutions.

First make a service to listen for routes changes and save the last previous route in a Behavior Subject, then provide this service in the main app.component in constructor then use this service to get the previous route you want when ever you want.

use case: you want to redirect the user to an advertise page then auto redirect him/her to where he did came from so you need the last previous route to do so.

// service : route-events.service.ts

import { Injectable } from '@angular/core';
import { Router, RoutesRecognized } from '@angular/router';
import { BehaviorSubject } from 'rxjs';
import { filter, pairwise } from 'rxjs/operators';
import { Location } from '@angular/common';

@Injectable()
export class RouteEventsService {

    // save the previous route
  public previousRoutePath = new BehaviorSubject<string>('');

  constructor(
    private router: Router,
    private location: Location
  ) {

    // ..initial prvious route will be the current path for now
    this.previousRoutePath.next(this.location.path());


    // on every route change take the two events of two routes changed(using pairwise)
    // and save the old one in a behavious subject to access it in another component
    // we can use if another component like intro-advertise need the previous route
    // because he need to redirect the user to where he did came from.
    this.router.events.pipe(
      filter(e => e instanceof RoutesRecognized),
      pairwise(),
        )
    .subscribe((event: any[]) => {
        this.previousRoutePath.next(event[0].urlAfterRedirects);
    });

  }
}

provide the service in app.module

  providers: [
    ....
    RouteEventsService,
    ....
  ]

Inject it in app.component

  constructor(
    private routeEventsService: RouteEventsService
  )

finally use the saved previous route in the component you want

  onSkipHandler(){
    // navigate the user to where he did came from
    this.router.navigate([this.routeEventsService.previousRoutePath.value]);
  }

There are several ways to perform HTTP GET and POST requests:

Method A: HttpClient (Preferred)

Available in: .NET Framework 4.5+, .NET Standard 1.1+, .NET Core 1.0+ .

It is currently the preferred approach, and is asynchronous and high performance. Use the built-in version in most cases, but for very old platforms there is a NuGet package.

using System.Net.Http;

Setup

It is recommended to instantiate one HttpClient for your application's lifetime and share it unless you have a specific reason not to.

private static readonly HttpClient client = new HttpClient();

See HttpClientFactory for a dependency injection solution.

• POST

  var values = new Dictionary<string, string>
  {
      { "thing1", "hello" },
      { "thing2", "world" }
  };
  
  var content = new FormUrlEncodedContent(values);
  
  var response = await client.PostAsync("http://www.example.com/recepticle.aspx", content);
  
  var responseString = await response.Content.ReadAsStringAsync();
  

• GET

  var responseString = await client.GetStringAsync("http://www.example.com/recepticle.aspx");
  

Method B: Third-Party Libraries

RestSharp

• POST

   var client = new RestClient("http://example.com");
   // client.Authenticator = new HttpBasicAuthenticator(username, password);
   var request = new RestRequest("resource/{id}");
   request.AddParameter("thing1", "Hello");
   request.AddParameter("thing2", "world");
   request.AddHeader("header", "value");
   request.AddFile("file", path);
   var response = client.Post(request);
   var content = response.Content; // Raw content as string
   var response2 = client.Post<Person>(request);
   var name = response2.Data.Name;
  

Flurl.Http

It is a newer library sporting a fluent API, testing helpers, uses HttpClient under the hood, and is portable. It is available via NuGet.

    using Flurl.Http;

• POST

  var responseString = await "http://www.example.com/recepticle.aspx"
      .PostUrlEncodedAsync(new { thing1 = "hello", thing2 = "world" })
      .ReceiveString();
  

• GET

  var responseString = await "http://www.example.com/recepticle.aspx"

Method C: HttpWebRequest (not recommended for new work)

Available in: .NET Framework 1.1+, .NET Standard 2.0+, .NET Core 1.0+. In .NET Core, it is mostly for compatibility -- it wraps HttpClient, is less performant, and won't get new features.

#if defined(CONDITION1) || defined(CONDITION2)

should work. :)

#ifdef is a bit less typing, but doesn't work well with more complex conditions

I'm using Eclipse and I copied your code and got the same error. I then opened up the project properties->Java Build Path -> Libraries->Add External JARs... c:\jrun4\lib\sqlitejdbc-v056.jar Worked like a charm. You may need to restart your web server if you've just copied the .jar file.

I've tried lots of options, but the one that worked for me was to:

1. Download the Git Password Manager from its Releases section

2. Try to do simple git fetch which will automatically bring the window(alternate to default windows one for example) and ask to enter username and password but with more elegant way than the standard one.

After correctly entering the credentials it worked, though I was getting an error before.

P.S. If you are getting "Wrong Credentials" kind of errors always check if the repository username and password are correct. If you hesitate just reset the password and try to use the same one in the Git Password manager window.

You need to destroy old data-table instance and then re-initialize data-table

First Check if data-table instance exist by using $.fn.dataTable.isDataTable

if exist then destroy it and then create new instance like this

    if ($.fn.dataTable.isDataTable('#dataTableExample')) {
        $('#dataTableExample').DataTable().destroy();
    }

    $('#dataTableExample').DataTable({
        responsive: true,
        destroy: true
    });

Is there any equivalent for the truststore? How can I view the trusted certificates?

Yes there is.The exact same command since keystore and truststore differ only in what they store i.e. private key or signed public key (certificate)

No other difference

use to .onBackPressed() to back Activity specify

@Override
public void onBackPressed(){
    backpress = (backpress + 1);
    Toast.makeText(getApplicationContext(), " Press Back again to Exit ", Toast.LENGTH_SHORT).show();

    if (backpress>1) {
        this.finish();
    }
}

An issue that DO arise in practical Android code is that comparing them with CharSequence.equals is valid but does not necessarily work as intended.

EditText t = (EditText )getView(R.id.myEditText); // Contains "OK"
Boolean isFalse = t.getText().equals("OK"); // will always return false.

Comparison should be made by

("OK").contentEquals(t.GetText()); 

System.out.println(isLeapYear);

should work just fine.

Incidentally, in

else if ((year % 4 == 0) && (year % 100 == 0))
    isLeapYear = false;

else if ((year % 4 == 0) && (year % 100 == 0) && (year % 400 == 0))
    isLeapYear = true;

the year % 400 part will never be reached because if (year % 4 == 0) && (year % 100 == 0) && (year % 400 == 0) is true, then (year % 4 == 0) && (year % 100 == 0) must have succeeded.

Maybe swap those two conditions or refactor them:

else if ((year % 4 == 0) && (year % 100 == 0))
    isLeapYear = (year % 400 == 0);

Something else that worked for me:

1. Right click the folder in src containing your main
2. You'll see an option "run 'file.main()'" with the run icon.
3. Click it, and then the run icon in the top right and bottom left will turn green from then on.

This will be possible via the navigator interface as shown below:

navigator.tcpPermission.requestPermission({remoteAddress:"127.0.0.1", remotePort:6789}).then(
  () => {
    // Permission was granted
    // Create a new TCP client socket and connect to remote host
    var mySocket = new TCPSocket("127.0.0.1", 6789);

    // Send data to server
    mySocket.writeable.write("Hello World").then(
        () => {

            // Data sent sucessfully, wait for response
            console.log("Data has been sent to server");
            mySocket.readable.getReader().read().then(
                ({ value, done }) => {
                    if (!done) {
                        // Response received, log it:
                        console.log("Data received from server:" + value);
                    }

                    // Close the TCP connection
                    mySocket.close();
                }
            );
        },
        e => console.error("Sending error: ", e)
    );
  }
);

More details are outlined in the w3.org tcp-udp-sockets documentation.

http://raw-sockets.sysapps.org/#interface-tcpsocket

https://www.w3.org/TR/tcp-udp-sockets/

Another alternative is to use Chrome Sockets

Creating connections

chrome.sockets.tcp.create({}, function(createInfo) {
  chrome.sockets.tcp.connect(createInfo.socketId,
    IP, PORT, onConnectedCallback);
});

Sending data

chrome.sockets.tcp.send(socketId, arrayBuffer, onSentCallback);

Receiving data

chrome.sockets.tcp.onReceive.addListener(function(info) {
  if (info.socketId != socketId)
    return;
  // info.data is an arrayBuffer.
});

You can use also attempt to use HTML5 Web Sockets (Although this is not direct TCP communication):

var connection = new WebSocket('ws://IPAddress:Port');

connection.onopen = function () {
  connection.send('Ping'); // Send the message 'Ping' to the server
};

http://www.html5rocks.com/en/tutorials/websockets/basics/

Your server must also be listening with a WebSocket server such as pywebsocket, alternatively you can write your own as outlined at Mozilla

Work out the solution according to what you want...

There are two things that getResource/getResourceAsStream() will get from the class it is called on...

1. The class loader
2. The starting location

So if you do

this.getClass().getResource("foo.txt");

it will attempt to load foo.txt from the same package as the "this" class and with the class loader of the "this" class. If you put a "/" in front then you are absolutely referencing the resource.

this.getClass().getResource("/x/y/z/foo.txt")

will load the resource from the class loader of "this" and from the x.y.z package (it will need to be in the same directory as classes in that package).

Thread.currentThread().getContextClassLoader().getResource(name)

will load with the context class loader but will not resolve the name according to any package (it must be absolutely referenced)

System.class.getResource(name)

Will load the resource with the system class loader (it would have to be absolutely referenced as well, as you won't be able to put anything into the java.lang package (the package of System).

Just take a look at the source. Also indicates that getResourceAsStream just calls "openStream" on the URL returned from getResource and returns that.

Try this (requires access to sys.dm_exec_connections):

SELECT DISTINCT 
    local_tcp_port 
FROM sys.dm_exec_connections 
WHERE local_tcp_port IS NOT NULL

Make sure you have the proper emulator and Android version installed. That solved the problem for me.

As the author of the above project i can say that yes it does support SSL.

I am currently working on a new version of the library that will be completely asynchronous to increase the speed with which it can interact with IMAP servers.

That code, while not complete, can be downloaded, along with the original synchronous library (which also supports SSL), from the code plex site linked to above.

Currently there is no way to apply a css to get your desired result . Why not use libraries like choosen or select2 . These allow you to style the way you want.

If you don want to use third party libraries then you can make a simple un-ordered list and play with some css.Here is thread you could follow

How to convert <select> dropdown into an unordered list using jquery?

Rookie, if you want to write a file to server by socket, how about using fileoutputstream instead of dataoutputstream? dataoutputstream is more fit for protocol-level read-write. it is not very reasonable for your code in bytes reading and writing. loop to read and write is necessary in java io. and also, you use a buffer way. flush is necessary. here is a code sample: http://www.rgagnon.com/javadetails/java-0542.html

in my case

my platform is x64

the Dll library(sdk) and the redistributable package is x64

so

1. in the solution explorer navigate to your project

2. open Properties

3. change the Platform target from AnyCPU to x64

You invoke the function with 2 parameters (@GenId and @Description):

EXEC etl.etl_M_Update_Promo @GenID, @Description

However you have declared the function to take 1 argument:

ALTER PROCEDURE [etl].[etl_M_Update_Promo]
    @GenId bigint = 0

SQL Server is telling you that [etl_M_Update_Promo] only takes 1 parameter (@GenId)

You can alter the procedure to take two parameters by specifying @Description.

ALTER PROCEDURE [etl].[etl_M_Update_Promo]
    @GenId bigint = 0,
    @Description NVARCHAR(50)
AS 

.... Rest of your code.

I used quite @Eyuel method:

• Download the nodejs msi from https://nodejs.org/en/#download
• Download npm zip from github https://github.com/npm/npm
• Extract the msi (with 7 Zip) in a directory "node"
• Set the PATH environment variable to add the "node" directory
• Extract the zip file from npm in a different directory (not under node directory)
• CD to the npm directory and run the command node cli.js install npm -gf

Now you should have node + npm working, use theses commands to check: node --version and npm --version

Update 27/07/2017 : I noticed that the latest version of node 8.2.1 with the latest version of npm are quite different from the one I was using at the time of this answer. The install with theses versions won't work. It is working with node 6.11.1 and npm 5.2.3. Also if you are running with a proxy don't forget this to connect on internet :

• export http_proxy=http://proxy:8080
• export https_proxy=http://proxy:8080
• npm config set proxy http://proxy:8080

An overview of the const and constexpr keywords

In C ++, if a const object is initialized with a constant expression, we can use our const object wherever a constant expression is required.

const int x = 10;
int a[x] = {0};

For example, we can make a case statement in switch.

constexpr can be used with arrays.

constexpr is not a type.

The constexpr keyword can be used in conjunction with the auto keyword.

constexpr auto x = 10;

struct Data {   // We can make a bit field element of struct.   
    int a:x;
 };

If we initialize a const object with a constant expression, the expression generated by that const object is now a constant expression as well.

Constant Expression : An expression whose value can be calculated at compile time.

x*5-4 // This is a constant expression. For the compiler, there is no difference between typing this expression and typing 46 directly.

Initialize is mandatory. It can be used for reading purposes only. It cannot be changed. Up to this point, there is no difference between the "const" and "constexpr" keywords.

NOTE: We can use constexpr and const in the same declaration.

constexpr const int* p;

Constexpr Functions

Normally, the return value of a function is obtained at runtime. But calls to constexpr functions will be obtained as a constant in compile time when certain conditions are met.

NOTE : Arguments sent to the parameter variable of the function in function calls or to all parameter variables if there is more than one parameter, if C.E the return value of the function will be calculated in compile time. !!!

constexpr int square (int a){
return a*a;
}

constexpr int a = 3;
constexpr int b = 5;

int arr[square(a*b+20)] = {0}; //This expression is equal to int arr[35] = {0};

In order for a function to be a constexpr function, the return value type of the function and the type of the function's parameters must be in the type category called "literal type".

The constexpr functions are implicitly inline functions.

An important point :

None of the constexpr functions need to be called with a constant expression.It is not mandatory. If this happens, the computation will not be done at compile time. It will be treated like a normal function call. Therefore, where the constant expression is required, we will no longer be able to use this expression.

The conditions required to be a constexpr function are shown below;

1 ) The types used in the parameters of the function and the type of the return value of the function must be literal type.

2 ) A local variable with static life time should not be used inside the function.

3 ) If the function is legal, when we call this function with a constant expression in compile time, the compiler calculates the return value of the function in compile time.

4 ) The compiler needs to see the code of the function, so constexpr functions will almost always be in the header files.

5 ) In order for the function we created to be a constexpr function, the definition of the function must be in the header file.Thus, whichever source file includes that header file will see the function definition.

Bonus

Normally with Default Member Initialization, static data members with const and integral types can be initialized within the class. However, in order to do this, there must be both "const" and "integral types".

If we use static constexpr then it doesn't have to be an integral type to initialize it inside the class. As long as I initialize it with a constant expression, there is no problem.

class Myclass  {
         const static int sx = 15;         // OK
         constexpr static int sy = 15;     // OK
         const static double sd = 1.5;     // ERROR
         constexpr static double sd = 1.5; // OK
 };

It's pretty simple really:

a[start:stop]  # items start through stop-1
a[start:]      # items start through the rest of the array
a[:stop]       # items from the beginning through stop-1
a[:]           # a copy of the whole array

There is also the step value, which can be used with any of the above:

a[start:stop:step] # start through not past stop, by step

The key point to remember is that the :stop value represents the first value that is not in the selected slice. So, the difference between stop and start is the number of elements selected (if step is 1, the default).

The other feature is that start or stop may be a negative number, which means it counts from the end of the array instead of the beginning. So:

a[-1]    # last item in the array
a[-2:]   # last two items in the array
a[:-2]   # everything except the last two items

Similarly, step may be a negative number:

a[::-1]    # all items in the array, reversed
a[1::-1]   # the first two items, reversed
a[:-3:-1]  # the last two items, reversed
a[-3::-1]  # everything except the last two items, reversed

Python is kind to the programmer if there are fewer items than you ask for. For example, if you ask for a[:-2] and a only contains one element, you get an empty list instead of an error. Sometimes you would prefer the error, so you have to be aware that this may happen.

Relation to slice() object

The slicing operator [] is actually being used in the above code with a slice() object using the : notation (which is only valid within []), i.e.:

a[start:stop:step]

is equivalent to:

a[slice(start, stop, step)]

Slice objects also behave slightly differently depending on the number of arguments, similarly to range(), i.e. both slice(stop) and slice(start, stop[, step]) are supported. To skip specifying a given argument, one might use None, so that e.g. a[start:] is equivalent to a[slice(start, None)] or a[::-1] is equivalent to a[slice(None, None, -1)].

While the :-based notation is very helpful for simple slicing, the explicit use of slice() objects simplifies the programmatic generation of slicing.

You can use the root.configure(background='your colour') example:- import tkinter root=tkiner.Tk() root.configure(background='pink')

The use of fork and exec exemplifies the spirit of UNIX in that it provides a very simple way to start new processes.

The fork call basically makes a duplicate of the current process, identical in almost every way. Not everything is copied over (for example, resource limits in some implementations) but the idea is to create as close a copy as possible.

The new process (child) gets a different process ID (PID) and has the PID of the old process (parent) as its parent PID (PPID). Because the two processes are now running exactly the same code, they can tell which is which by the return code of fork - the child gets 0, the parent gets the PID of the child. This is all, of course, assuming the fork call works - if not, no child is created and the parent gets an error code.

The exec call is a way to basically replace the entire current process with a new program. It loads the program into the current process space and runs it from the entry point.

So, fork and exec are often used in sequence to get a new program running as a child of a current process. Shells typically do this whenever you try to run a program like find - the shell forks, then the child loads the find program into memory, setting up all command line arguments, standard I/O and so forth.

But they're not required to be used together. It's perfectly acceptable for a program to fork itself without execing if, for example, the program contains both parent and child code (you need to be careful what you do, each implementation may have restrictions). This was used quite a lot (and still is) for daemons which simply listen on a TCP port and fork a copy of themselves to process a specific request while the parent goes back to listening.

Similarly, programs that know they're finished and just want to run another program don't need to fork, exec and then wait for the child. They can just load the child directly into their process space.

Some UNIX implementations have an optimized fork which uses what they call copy-on-write. This is a trick to delay the copying of the process space in fork until the program attempts to change something in that space. This is useful for those programs using only fork and not exec in that they don't have to copy an entire process space.

If the exec is called following fork (and this is what happens mostly), that causes a write to the process space and it is then copied for the child process.

Note that there is a whole family of exec calls (execl, execle, execve and so on) but exec in context here means any of them.

The following diagram illustrates the typical fork/exec operation where the bash shell is used to list a directory with the ls command:

+--------+
| pid=7  |
| ppid=4 |
| bash   |
+--------+
    |
    | calls fork
    V
+--------+             +--------+
| pid=7  |    forks    | pid=22 |
| ppid=4 | ----------> | ppid=7 |
| bash   |             | bash   |
+--------+             +--------+
    |                      |
    | waits for pid 22     | calls exec to run ls
    |                      V
    |                  +--------+
    |                  | pid=22 |
    |                  | ppid=7 |
    |                  | ls     |
    V                  +--------+
+--------+                 |
| pid=7  |                 | exits
| ppid=4 | <---------------+

The original question addresses a specific narrow use case. For those who need more generic answers here are some examples:

Creating a new column using data from other columns

Given the dataframe below:

import pandas as pd
import numpy as np

df = pd.DataFrame([['dog', 'hound', 5],
                   ['cat', 'ragdoll', 1]],
                  columns=['animal', 'type', 'age'])

In[1]:
Out[1]:
  animal     type  age
----------------------
0    dog    hound    5
1    cat  ragdoll    1

Below we are adding a new description column as a concatenation of other columns by using the + operation which is overridden for series. Fancy string formatting, f-strings etc won't work here since the + applies to scalars and not 'primitive' values:

df['description'] = 'A ' + df.age.astype(str) + ' years old ' \
                    + df.type + ' ' + df.animal

In [2]: df
Out[2]:
  animal     type  age                description
-------------------------------------------------
0    dog    hound    5    A 5 years old hound dog
1    cat  ragdoll    1  A 1 years old ragdoll cat

We get 1 years for the cat (instead of 1 year) which we will be fixing below using conditionals.

Modifying an existing column with conditionals

Here we are replacing the original animal column with values from other columns, and using np.where to set a conditional substring based on the value of age:

# append 's' to 'age' if it's greater than 1
df.animal = df.animal + ", " + df.type + ", " + \
    df.age.astype(str) + " year" + np.where(df.age > 1, 's', '')

In [3]: df
Out[3]:
                 animal     type  age
-------------------------------------
0   dog, hound, 5 years    hound    5
1  cat, ragdoll, 1 year  ragdoll    1

Modifying multiple columns with conditionals

A more flexible approach is to call .apply() on an entire dataframe rather than on a single column:

def transform_row(r):
    r.animal = 'wild ' + r.type
    r.type = r.animal + ' creature'
    r.age = "{} year{}".format(r.age, r.age > 1 and 's' or '')
    return r

df.apply(transform_row, axis=1)

In[4]:
Out[4]:
         animal            type      age
----------------------------------------
0    wild hound    dog creature  5 years
1  wild ragdoll    cat creature   1 year

In the code above the transform_row(r) function takes a Series object representing a given row (indicated by axis=1, the default value of axis=0 will provide a Series object for each column). This simplifies processing since we can access the actual 'primitive' values in the row using the column names and have visibility of other cells in the given row/column.

Try this:

select {
    display: -webkit-box;
    display: -moz-box;
    display: -ms-flexbox;
    display: -ms-flexbox;
}

Rob W answer helped me figure out how to pause a video over iframe when a slider is hidden. Yet, I needed some modifications before I could get it to work. Here is snippet of my html:

<div class="flexslider" style="height: 330px;">
  <ul class="slides">
    <li class="post-64"><img src="http://localhost/.../Banner_image.jpg"></li>
    <li class="post-65><img  src="http://localhost/..../banner_image_2.jpg "></li>
    <li class="post-67 ">
        <div class="fluid-width-video-wrapper ">
            <iframe frameborder="0 " allowfullscreen=" " src="//www.youtube.com/embed/video-ID?enablejsapi=1 " id="fitvid831673 "></iframe>
        </div>
    </li>
  </ul>
</div>

Observe that this works on localhosts and also as Rob W mentioned "enablejsapi=1" was added to the end of the video URL.

Following is my JS file:

jQuery(document).ready(function($){
    jQuery(".flexslider").click(function (e) {
        setTimeout(checkiframe, 1000); //Checking the DOM if iframe is hidden. Timer is used to wait for 1 second before checking the DOM if its updated

    });

In the pom.xml (after loading effective pom.xml in eclipse), you may see it "http://repo.maven.apache.org/maven2" under central repository instead of "https://repo.maven.apache.org/maven2". Fix it

Well if you are getting into a linux machine you can use the package manager of that linux distro.

If you are using Ubuntu just use apt-get search python, check the list and do apt-get install python2.7 (not sure if python2.7 or python-2.7, check the list)

You could use yum in fedora and do the same.

if you want to install it on your windows machine i dont know any package manager, i would download the wget for windows, donwload the package from python.org and install it

To convert an integer to a float in Python you can use the following:

float_version = float(int_version)

The reason you are getting 0 is that Python 2 returns an integer if the mathematical operation (here a division) is between two integers. So while the division of 144 by 314 is 0.45~~~, Python converts this to integer and returns just the 0 by eliminating all numbers after the decimal point.

Alternatively you can convert one of the numbers in any operation to a float since an operation between a float and an integer would return a float. In your case you could write float(144)/314 or 144/float(314). Another, less generic code, is to say 144.0/314. Here 144.0 is a float so it’s the same thing.

Possibly related, if you want to initialize and fill an array with a range of values, use PHP's (wait for it...) range function:

$a = range(1, 5);  // array(1,2,3,4,5)
$a = range(0, 10, 2); // array(0,2,4,6,8,10)

Here are some examples:

> z$mean <- rowMeans(subset(z, select = c(x, y)), na.rm = TRUE)
> z
  w x  y mean
1 5 1  1    1
2 6 2  2    2
3 7 3  3    3
4 8 4 NA    4

weighted mean

> z$y <- rev(z$y)
> z
  w x  y mean
1 5 1 NA    1
2 6 2  3    2
3 7 3  2    3
4 8 4  1    4
> 
> weight <- c(1, 2) # x * 1/3 + y * 2/3
> z$wmean <- apply(subset(z, select = c(x, y)), 1, function(d) weighted.mean(d, weight, na.rm = TRUE))
> z
  w x  y mean    wmean
1 5 1 NA    1 1.000000
2 6 2  3    2 2.666667
3 7 3  2    3 2.333333
4 8 4  1    4 2.000000

In my case the sub domain name causes the problem. Here are details

I used app_development.something.com, here underscore(_) sub domain is creating CORS error. After changing app_development to app-development it works fine.

Android doesn't support keeping the spaces at the end of the string in String.xml file so if you want space after string you need to use this unicode in between the words.

\u0020

It is a unicode space character.

You say that the matrices are the same dimensions, and yet you are trying to perform matrix multiplication on them. Multiplication of matrices with the same dimension is only possible if they are square. In your case, you get an assertion error, because the dimensions are not square. You have to be careful when multiplying matrices, as there are two possible meanings of multiply.

Matrix multiplication is where two matrices are multiplied directly. This operation multiplies matrix A of size [a x b] with matrix B of size [b x c] to produce matrix C of size [a x c]. In OpenCV it is achieved using the simple * operator:

C = A * B

Element-wise multiplication is where each pixel in the output matrix is formed by multiplying that pixel in matrix A by its corresponding entry in matrix B. The input matrices should be the same size, and the output will be the same size as well. This is achieved using the mul() function:

output = A.mul(B);

Yes, it is because you are using auto layout. Setting the view frame and resizing mask will not work.

You should read Working with Auto Layout Programmatically and Visual Format Language.

You will need to get the current constraints, add the text field, adjust the contraints for the text field, then add the correct constraints on the text field.

I use the following method in my JavaFX applications.

newWindowButton.setOnMouseClicked((event) -> {
    try {
        FXMLLoader fxmlLoader = new FXMLLoader();
        fxmlLoader.setLocation(getClass().getResource("NewWindow.fxml"));
        /* 
         * if "fx:controller" is not set in fxml
         * fxmlLoader.setController(NewWindowController);
         */
        Scene scene = new Scene(fxmlLoader.load(), 600, 400);
        Stage stage = new Stage();
        stage.setTitle("New Window");
        stage.setScene(scene);
        stage.show();
    } catch (IOException e) {
        Logger logger = Logger.getLogger(getClass().getName());
        logger.log(Level.SEVERE, "Failed to create new Window.", e);
    }
});

try this:

update `list`
set `test` = `number`

I know it is a very old question, but better update it with new information.

You can install service by using sc command:

InstallService.bat:

@echo OFF
echo Stopping old service version...
net stop "[YOUR SERVICE NAME]"
echo Uninstalling old service version...
sc delete "[YOUR SERVICE NAME]"

echo Installing service...
rem DO NOT remove the space after "binpath="!
sc create "[YOUR SERVICE NAME]" binpath= "[PATH_TO_YOUR_SERVICE_EXE]" start= auto
echo Starting server complete
pause

With SC, you can do a lot more things as well: uninstalling the old service (if you already installed it before), checking if service with same name exists... even set your service to autostart.

One of many references: creating a service with sc.exe; how to pass in context parameters

I have done by both this way & InstallUtil. Personally I feel that using SC is cleaner and better for your health.

If you have a Decimal or similar numeric type, you can use:

Math.Round(myNumber, 2)

EDIT: So, in your case, it would be:

Public Class Form1
  Private Sub btncalc_Click(ByVal sender As System.Object,
                            ByVal e As System.EventArgs) Handles btncalc.Click
    txtA.Text = Math.Round((Val(txtD.Text) / Val(txtC.Text) * Val(txtF.Text) / Val(txtE.Text)), 2)
    txtB.Text = Math.Round((Val(txtA.Text) * 1000 / Val(txtG.Text)), 2)
  End Sub
End Class

You haven't at time of writing described what you are going to do with the response or what its content type is. An answer already contains a very basic usage of MSXML2.XMLHTTP (I recommend the more explicit MSXML2.XMLHTTP.3.0 progID) however you may need to do different things with the response, it may not be text.

The XMLHTTP also has a responseBody property which is a byte array version of the reponse and there is a responseStream which is an IStream wrapper for the response.

Note that in a server-side requirement (e.g., VBScript hosted in ASP) you would use MSXML.ServerXMLHTTP.3.0 or WinHttp.WinHttpRequest.5.1 (which has a near identical interface).

Here is an example of using XmlHttp to fetch a PDF file and store it:-

Dim oXMLHTTP
Dim oStream

Set oXMLHTTP = CreateObject("MSXML2.XMLHTTP.3.0")

oXMLHTTP.Open "GET", "http://someserver/folder/file.pdf", False
oXMLHTTP.Send

If oXMLHTTP.Status = 200 Then
    Set oStream = CreateObject("ADODB.Stream")
    oStream.Open
    oStream.Type = 1
    oStream.Write oXMLHTTP.responseBody
    oStream.SaveToFile "c:\somefolder\file.pdf"
    oStream.Close
End If

In case you don't want to pollute your model with annotations and want to perform some custom operations, you could use mixins.

ObjectMapper mapper = new ObjectMapper();
SimpleModule simpleModule = new SimpleModule();
simpleModule.setMixInAnnotation(Person.class, PersonMixin.class);
mapper.registerModule(simpleModule);

Override age:

public abstract class PersonMixin {
    @JsonSerialize(using = PersonAgeSerializer.class)
    public String age;
}

Do whatever you need with the age:

public class PersonAgeSerializer extends JsonSerializer<Integer> {
    @Override
    public void serialize(Integer integer, JsonGenerator jsonGenerator, SerializerProvider serializerProvider) throws IOException {
        jsonGenerator.writeString(String.valueOf(integer * 52) + " months");
    }
}

Have a look at <openssl/pem.h>. It gives possible BEGIN markers.

I do this to create my own validation annotation and validator:

ValidCardType.java(annotation to put on methods/fields)

@Constraint(validatedBy = {CardTypeValidator.class})
@Documented
@Target( { ElementType.ANNOTATION_TYPE, ElementType.METHOD, ElementType.FIELD })
@Retention(RetentionPolicy.RUNTIME)
public @interface ValidCardType {
    String message() default "Incorrect card type, should be among: \"MasterCard\" | \"Visa\"";
    Class<?>[] groups() default {};
    Class<? extends Payload>[] payload() default {};
}

And, the validator to trigger the check: CardTypeValidator.java:

public class CardTypeValidator implements ConstraintValidator<ValidCardType, String> {
    private static final String[] ALL_CARD_TYPES = {"MasterCard", "Visa"};

    @Override
    public void initialize(ValidCardType status) {
    }
    public boolean isValid(String value, ConstraintValidatorContext context) {
        return (Arrays.asList(ALL_CARD_TYPES).contains(value));
    }
}

You can do something very similar to check @NotNull.

git reset HEAD^

then the modified files should show up.

You could move the modified files into a new branch

use,

git checkout -b newbranch

git checkout commit -m "files modified"

git push origin newbranch

git checkout master

then you should be on a clean branch, and your changes should be stored in newbranch. You could later just merge this change into the master branch

This is an answer I haven't seen much around (this it was in a comment somewhere) although yes taking the app off development mode will work this can be bad for security or really annoying if the app isn't ready yet but you need to submit the app for review on account of needing access to special permissions (e.g. user_birthday).

What I did instead to fix the error was go to https://developers.facebook.com/sa/apps/{appId}/roles/ or from the app dashboard click roles on the left side

Then add the user account(s) to either developer or tester. Developers will need to be verified by mobile and will get access to the app to make changes but a tester will only need to be verified by email (not sure if even this is necessary but it probably is) and will only be able to use the API instead of make changes to settings.

If the app is ready for the public, obviously just take the app off development mode.

Is this what you're looking for?

#include <chrono>
#include <iostream>

int main()
{
    typedef std::chrono::high_resolution_clock Time;
    typedef std::chrono::milliseconds ms;
    typedef std::chrono::duration<float> fsec;
    auto t0 = Time::now();
    auto t1 = Time::now();
    fsec fs = t1 - t0;
    ms d = std::chrono::duration_cast<ms>(fs);
    std::cout << fs.count() << "s\n";
    std::cout << d.count() << "ms\n";
}

which for me prints out:

VARCHAR means that it's a variable-length character, so it's only going to take as much space as is necessary. But if you knew something about the underlying structure, it may make sense to restrict VARCHAR to some maximum amount.

For instance, if you were storing comments from the user, you may limit the comment field to only 4000 characters; if so, it doesn't really make any sense to make the sql table have a field that's larger than VARCHAR(4000).

You must always override an abstract function.

Thus:

• Abstract functions - when the inheritor must provide its own implementation
• Virtual - when it is up to the inheritor to decide

Set-ExecutionPolicy Unrestricted -Scope CurrentUser

This will set the execution policy for the current user (stored in HKEY_CURRENT_USER) rather than the local machine (HKEY_LOCAL_MACHINE). This is useful if you don't have administrative control over the computer.

Here's the XPath approach but with a minimum of XPath jargon.

Regular selection based on element attribute values (for comparison):

// for matching <element class="foo bar baz">...</element> by 'bar'
var things = document.querySelectorAll('[class*="bar"]');
for (var i = 0; i < things.length; i++) {
    things[i].style.outline = '1px solid red';
}

XPath selection based on text within element.

// for matching <element>foo bar baz</element> by 'bar'
var things = document.evaluate('//*[contains(text(),"bar")]',document,null,XPathResult.ORDERED_NODE_SNAPSHOT_TYPE,null);
for (var i = 0; i < things.snapshotLength; i++) {
    things.snapshotItem(i).style.outline = '1px solid red';
}

And here's with case-insensitivity since text is more volatile:

// for matching <element>foo bar baz</element> by 'bar' case-insensitively
var things = document.evaluate('//*[contains(translate(text(),"ABCDEFGHIJKLMNOPQRSTUVWXYZ","abcdefghijklmnopqrstuvwxyz"),"bar")]',document,null,XPathResult.ORDERED_NODE_SNAPSHOT_TYPE,null);
for (var i = 0; i < things.snapshotLength; i++) {
    things.snapshotItem(i).style.outline = '1px solid red';
}

If you don't have the token at the time of the call is made, You will have to make two calls, one to get the token and the other to extract the token form the response, pay attention to

grep token | cut -d, -f1 | cut -d\" -f4

as it is the part which is dealing with extracting the token from the response.

echo "Getting token response and extracting token"    
def token = sh (returnStdout: true, script: """
    curl -S -i -k -X POST https://www.example.com/getToken -H \"Content-Type: application/json\" -H \"Accept: application/json\" -d @requestFile.json | grep token | cut -d, -f1 | cut -d\\" -f4
""").split()

After extracting the token you can use the token to make subsequent calls as follows.

echo "Token : ${token[-1]}"       
echo "Making calls using token..."       
curl -S -i -k  -H "Accept: application/json" -H "Content-Type: application/json" -H "Authorization: Bearer ${token[-1]}" https://www.example.com/api/resources 

You would use it if you are using RenderAction in any of your views, usually to render a partial view.

The reason for marking it with [ChildActionOnly] is that you need the controller method to be public so you can call it with RenderAction but you don't want someone to be able to navigate to a URL (e.g. /Controller/SomeChildAction) and see the results of that action directly.

I was facing the same issue and then I closed and reopened cmd.exe to get mvn -vto propagate to my command prompt.

If cmd was open when you set the variables they will not be available in that session.

BOUML is free, can reverse-engineer Java and C++

A different approach would be to using multi-dimensional arrays:

var driversCounter = [
    ["one", 1], 
    ["two", 2], 
    ["three", 3], 
    ["four", 4], 
    ["five", 5]
]

and access the value by driverCounter[k][j], where j=0,1 in the case.
Add it in a drop down list by:

var dd = document.getElementById('your_dropdown_element');
for(i=0;i<driversCounter.length-1;i++)
{
    dd.options.add(opt);
    opt.text = driversCounter[i][0];
    opt.value = driversCounter[i][1];
}

Just a small detail that I think is missing in above answers.

If your child activity can be opened from multiple parent activities then you can check if you need to do setResult or not, based on if your activity was opened by startActivity or startActivityForResult. You can achieve this by using getCallingActivity(). More info here.

#!/bin/sh
if [ "$#" -ne 1 ] || ! [ -d "$1" ]; then
  echo "Usage: $0 DIRECTORY" >&2
  exit 1
fi

Translation: If number of arguments is not (numerically) equal to 1 or the first argument is not a directory, output usage to stderr and exit with a failure status code.

More friendly error reporting:

#!/bin/sh
if [ "$#" -ne 1 ]; then
  echo "Usage: $0 DIRECTORY" >&2
  exit 1
fi
if ! [ -e "$1" ]; then
  echo "$1 not found" >&2
  exit 1
fi
if ! [ -d "$1" ]; then
  echo "$1 not a directory" >&2
  exit 1
fi

If you're not wanting to save changes set savechanges to false

    Sub CloseBook2()
        ActiveWorkbook.Close savechanges:=False
    End Sub

for more examples, http://support.microsoft.com/kb/213428 and i believe in the past I've just used

    ActiveWorkbook.Close False

You can use the function RESHAPE:

B = reshape(A.',1,[]);

I found a way to get the APK's package name in a non-root device. it's not so elegant, but works all the time.

Step 1: on your device, open the target APK

Step 2: on PC cmd window, type this commands:

 adb shell dumpsys activity a > dump.txt

because the output of this command is numerous, redirect to a file is recommended.

Step 3: open this dump.txt file with any editor.

for device befor Android 4.4:
the beginning of the file would be looked like this:

ACTIVITY MANAGER ACTIVITIES (dumpsys activity activities)  
  Main stack:  
  * TaskRecord{41aa9ed0 #4 A com.tencent.mm U 0}  
    numActivities=1 rootWasReset=true userId=0  
    affinity=com.tencent.mm  
    intent={act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] flg=0x10600000 cmp=com.tencent.mm/.ui.LauncherUI}  
    realActivity=com.tencent.mm/.ui.LauncherUI  
    askedCompatMode=false  
    lastThumbnail=null lastDescription=null  
    lastActiveTime=19915965 (inactive for 10s)  
    * Hist #9: ActivityRecord{41ba1a30 u0 com.tencent.mm/.ui.LauncherUI}  
        packageName=com.tencent.mm processName=com.tencent.mm 

the package name is in the 3rd line, com.tencent.mm for this example.

for Android 4.4 and later:
the dumpsys output has changed a little. try search "Stack #1", the package name would be very close below it.

Also, search "baseDir", you will find the full path of the apk file!

Use the .val() method.

Also I think you meant to use $("#txtEmail") as $("txtEmail") returns elements of type <txtEmail> which you probably don't have.

See here at the jQuery documentation.

Also jQuery val() method.

In an AngularJS directive the scope allows you to access the data in the attributes of the element to which the directive is applied.

This is illustrated best with an example:

<div my-customer name="Customer XYZ"></div>

and the directive definition:

angular.module('myModule', [])
.directive('myCustomer', function() {
  return {
    restrict: 'E',
    scope: {
      customerName: '@name'
    },
    controllerAs: 'vm',
    bindToController: true,
    controller: ['$http', function($http) {
      var vm = this;

      vm.doStuff = function(pane) {
        console.log(vm.customerName);
      };
    }],
    link: function(scope, element, attrs) {
      console.log(scope.customerName);
    }
  };
});

When the scope property is used the directive is in the so called "isolated scope" mode, meaning it can not directly access the scope of the parent controller.

In very simple terms, the meaning of the binding symbols is:

someObject: '=' (two-way data binding)

someString: '@' (passed directly or through interpolation with double curly braces notation {{}})

someExpression: '&' (e.g. hideDialog())

This information is present in the AngularJS directive documentation page, although somewhat spread throughout the page.

The symbol > is not part of the syntax.

However, < does exist as part of the AngularJS component bindings and means one way binding.

Directly changing eclipse file is not a good idea, no matter facet or ini, unless it could be changed in eclipse. Had the same problem, with jdk1.8 installed. Change it to jdk 1.7.

Besides, according to https://wiki.eclipse.org/Eclipse/Installation, both LUNA and MARS need 1.7. So just ensure you have it installed.

in my case, I need to have my wcf running for more than 2 hours. Setting and did not work at all. The wcf did not execute longer than maybe 20~30 minutes. So I changed the idle timeout setting of application pool in IIS manager then it worked! In IIS manager, choose your application pool and right click on it and choose advanced settings then change the idle timeout setting to any minutes you want. So, I think setting the web.config and setting the application pool are both needed.

Using Postgres I had issues with DATEDIFF, but had success with this:

  DATE_PART('day',(delivery_time)::timestamp - (placed_time)::timestamp) * 24 + 
  DATE_PART('hour',(delivery_time)::timestamp - (placed_time)::timestamp) +
  DATE_PART('minute',(delivery_time)::timestamp - (placed_time)::timestamp) / 60

which gave me an output like "14.3"

For showing result of batch file in text file, you can use

this command

chdir > test.txt

This command will redirect result to test.txt.

When you open test.txt you will found current path of directory in test.txt
