Sometimes, you need to list the variables of an object and not for debugging purposes. The right way to do it is using get_object_vars($object). It returns an array that has all the class variables and their value. You can then loop through them in a foreach loop. If used within the object itself, simply do get_object_vars($this)

setInterval()

setInterval is a time interval based code execution method that has the native ability to repeatedly run specified script when the interval is reached. It should not be nested into its callback function by the script author to make it loop, since it loops by default. It will keep firing at the interval unless you call clearInterval().

if you want to loop code for animations or clocks Then use setInterval.

function doStuff() {
alert("run your code here when time interval is reached");
}
var myTimer = setInterval(doStuff, 5000);

setTimeout()

setTimeout is a time based code execution method that will execute script only one time when the interval is reached, and not repeat again unless you gear it to loop the script by nesting the setTimeout object inside of the function it calls to run. If geared to loop, it will keep firing at the interval unless you call clearTimeout().

function doStuff() {
alert("run your code here when time interval is reached");
}
var myTimer = setTimeout(doStuff, 5000);

if you want something to happen one time after some seconds Then use setTimeout... because it only executes one time when the interval is reached.

What are the options to clone or copy a list in Python?

In Python 3, a shallow copy can be made with:

a_copy = a_list.copy()

In Python 2 and 3, you can get a shallow copy with a full slice of the original:

a_copy = a_list[:]

Explanation

There are two semantic ways to copy a list. A shallow copy creates a new list of the same objects, a deep copy creates a new list containing new equivalent objects.

Shallow list copy

A shallow copy only copies the list itself, which is a container of references to the objects in the list. If the objects contained themselves are mutable and one is changed, the change will be reflected in both lists.

There are different ways to do this in Python 2 and 3. The Python 2 ways will also work in Python 3.

Python 2

In Python 2, the idiomatic way of making a shallow copy of a list is with a complete slice of the original:

a_copy = a_list[:]

You can also accomplish the same thing by passing the list through the list constructor,

a_copy = list(a_list)

but using the constructor is less efficient:

>>> timeit
>>> l = range(20)
>>> min(timeit.repeat(lambda: l[:]))
0.30504298210144043
>>> min(timeit.repeat(lambda: list(l)))
0.40698814392089844

Python 3

In Python 3, lists get the list.copy method:

a_copy = a_list.copy()

In Python 3.5:

>>> import timeit
>>> l = list(range(20))
>>> min(timeit.repeat(lambda: l[:]))
0.38448613602668047
>>> min(timeit.repeat(lambda: list(l)))
0.6309100328944623
>>> min(timeit.repeat(lambda: l.copy()))
0.38122922903858125

Making another pointer does not make a copy

Using new_list = my_list then modifies new_list every time my_list changes. Why is this?

my_list is just a name that points to the actual list in memory. When you say new_list = my_list you're not making a copy, you're just adding another name that points at that original list in memory. We can have similar issues when we make copies of lists.

>>> l = [[], [], []]
>>> l_copy = l[:]
>>> l_copy
[[], [], []]
>>> l_copy[0].append('foo')
>>> l_copy
[['foo'], [], []]
>>> l
[['foo'], [], []]

The list is just an array of pointers to the contents, so a shallow copy just copies the pointers, and so you have two different lists, but they have the same contents. To make copies of the contents, you need a deep copy.

Deep copies

To make a deep copy of a list, in Python 2 or 3, use deepcopy in the copy module:

import copy
a_deep_copy = copy.deepcopy(a_list)

To demonstrate how this allows us to make new sub-lists:

>>> import copy
>>> l
[['foo'], [], []]
>>> l_deep_copy = copy.deepcopy(l)
>>> l_deep_copy[0].pop()
'foo'
>>> l_deep_copy
[[], [], []]
>>> l
[['foo'], [], []]

And so we see that the deep copied list is an entirely different list from the original. You could roll your own function - but don't. You're likely to create bugs you otherwise wouldn't have by using the standard library's deepcopy function.

Don't use eval

You may see this used as a way to deepcopy, but don't do it:

problematic_deep_copy = eval(repr(a_list))

1. It's dangerous, particularly if you're evaluating something from a source you don't trust.
2. It's not reliable, if a subelement you're copying doesn't have a representation that can be eval'd to reproduce an equivalent element.
3. It's also less performant.

In 64 bit Python 2.7:

>>> import timeit
>>> import copy
>>> l = range(10)
>>> min(timeit.repeat(lambda: copy.deepcopy(l)))
27.55826997756958
>>> min(timeit.repeat(lambda: eval(repr(l))))
29.04534101486206

on 64 bit Python 3.5:

>>> import timeit
>>> import copy
>>> l = list(range(10))
>>> min(timeit.repeat(lambda: copy.deepcopy(l)))
16.84255409205798
>>> min(timeit.repeat(lambda: eval(repr(l))))
34.813894678023644

I came across this problem as well. Given 3 inputs: field[], field2[], field3[]

You can access each of these fields dynamically. Since each field will be an array, the related fields will all share the same array key. For example, given input data:

• Bob, [email protected], male
• Mark, [email protected], male

Bob and his email and sex will share the same key. With this in mind, you can access the data in a for loop like this:

    for($x = 0; $x < count($first_name); $x++ )
    {
        echo $first_name[$x];
        echo $email[$x];
        echo $sex[$x];
        echo "<br/>";
    }

This scales as well. All you need to do is add your respective array vars whenever you need new fields to be added.

The limit for the length of a command line is not imposed by the shell, but by the operating system. This limit is usually in the range of hundred kilobytes. POSIX denotes this limit ARG_MAX and on POSIX conformant systems you can query it with

$ getconf ARG_MAX    # Get argument limit in bytes

E.g. on Cygwin this is 32000, and on the different BSDs and Linux systems I use it is anywhere from 131072 to 2621440.

If you need to process a list of files exceeding this limit, you might want to look at the xargs utility, which calls a program repeatedly with a subset of arguments not exceeding ARG_MAX.

To answer your specific question, yes, it is possible to attempt to run a command with too long an argument list. The shell will error with a message along "argument list too long".

Note that the input to a program (as read on stdin or any other file descriptor) is not limited (only by available program resources). So if your shell script reads a string into a variable, you are not restricted by ARG_MAX. The restriction also does not apply to shell-builtins.

No. Actually it's the "same" as

char array[] = {'O', 'n', 'e', ..... 'i','c','\0');

Every character is a separate element, with an additional \0 character as a string terminator.

I quoted "same", because there are some differences between char * array and char array[]. If you want to read more, take a look at C: differences between char pointer and array

Now in modern browsers, console.log() can be used by pressing F12 key. The picture will be helpful to understand the concept clearly.

The most secure way (in terms of special character and data type handling) is using json_encode():

var spge = <?php echo json_encode($cname); ?>;

CSS has become a very powerful tool over the years and it has hacks for a lot of things javaScript can do

There is a hack in CSS for using conditional statements/logic.

It involves using the symbol '~'

Let me further illustrate with an example.

Let's say you want a background to slide into the page when a button is clicked. All you need to do is use a radio checkbox. Style the label for the radio underneath the button so that when the button is pressed the checkbox is also pressed.

Then you use the code below

.checkbox:checked ~ .background{
opacity:1
width: 100%
}

This code simply states IF the checkbox is CHECKED then open up the background ELSE leave it as it is.

I like Tom Faust's answer the best. Here's a C# version of his solution, but simplifying things a bit.

var codecs = ImageCodecInfo.GetImageEncoders(); 
var codecFilter = "Image Files|"; 
foreach (var codec in codecs) 
{
    codecFilter += codec.FilenameExtension + ";"; 
} 
dialog.Filter = codecFilter;

A numpy single-element array is mutable and yet for most purposes, it can be evaluated as if it was a numerical python variable. Therefore, it's a more convenient by-reference number container than a single-element list.

    import numpy as np
    def triple_var_by_ref(x):
        x[0]=x[0]*3
    a=np.array([2])
    triple_var_by_ref(a)
    print(a+1)

output:

3

There's a ES6 shorthand import, you can reference. More readable and easy to type.

import React, { Component } from 'react';
import { arrayOf, shape, number } from 'prop-types';

class ExampleComponent extends Component {
  static propTypes = {
    annotationRanges: arrayOf(shape({
      start: number,
      end: number,
    })).isRequired,
  }

  static defaultProps = {
     annotationRanges: [],
  }
}

So the first part of the answer is how to do what the subject asks as this was how I initially interpreted it and a few people seemed to find helpful. The question was since clarified and I've extended the answer to address that.

Setting a timer

First you need to create a Timer (I'm using the java.util version here):

import java.util.Timer;

..

Timer timer = new Timer();

To run the task once you would do:

timer.schedule(new TimerTask() {
  @Override
  public void run() {
    // Your database code here
  }
}, 2*60*1000);
// Since Java-8
timer.schedule(() -> /* your database code here */, 2*60*1000);

To have the task repeat after the duration you would do:

timer.scheduleAtFixedRate(new TimerTask() {
  @Override
  public void run() {
    // Your database code here
  }
}, 2*60*1000, 2*60*1000);

// Since Java-8
timer.scheduleAtFixedRate(() -> /* your database code here */, 2*60*1000, 2*60*1000);

Making a task timeout

To specifically do what the clarified question asks, that is attempting to perform a task for a given period of time, you could do the following:

ExecutorService service = Executors.newSingleThreadExecutor();

try {
    Runnable r = new Runnable() {
        @Override
        public void run() {
            // Database task
        }
    };

    Future<?> f = service.submit(r);

    f.get(2, TimeUnit.MINUTES);     // attempt the task for two minutes
}
catch (final InterruptedException e) {
    // The thread was interrupted during sleep, wait or join
}
catch (final TimeoutException e) {
    // Took too long!
}
catch (final ExecutionException e) {
    // An exception from within the Runnable task
}
finally {
    service.shutdown();
}

This will execute normally with exceptions if the task completes within 2 minutes. If it runs longer than that, the TimeoutException will be throw.

One issue is that although you'll get a TimeoutException after the two minutes, the task will actually continue to run, although presumably a database or network connection will eventually time out and throw an exception in the thread. But be aware it could consume resources until that happens.

No, there isn't a syntax for extracting text using regular expressions. You have to use the ordinary string manipulation functions.

Alternatively select the entire value from the database (or the first n characters if you are worried about too much data transfer) and then use a regular expression on the client.

REGEXP_COUNT wasn't added until Oracle 11i. Here's an Oracle 10g solution, adopted from Art's solution.

SELECT trim(regexp_substr('Err1, Err2, Err3', '[^,]+', 1, LEVEL)) str_2_tab
  FROM dual
CONNECT BY LEVEL <=
  LENGTH('Err1, Err2, Err3')
    - LENGTH(REPLACE('Err1, Err2, Err3', ',', ''))
    + 1;

If you didn't commit it to the master branch yet, its easy:

• get off the master branch (like git checkout -b oops/fluke/dang)
• commit your changes there (like git add -u; git commit;)
• go back the master branch (like git checkout master)

Your changes will be saved in branch oops/fluke/dang; master will be as it was.

Do not use a KeyListener for this as you'll miss much including pasting of text. Also a KeyListener is a very low-level construct and as such, should be avoided in Swing applications.

The solution has been described many times on SO: Use a DocumentFilter. There are several examples of this on this site, some written by me.

For example: using-documentfilter-filterbypass

Also for tutorial help, please look at: Implementing a DocumentFilter.

Edit

For instance:

import javax.swing.JOptionPane;
import javax.swing.JPanel;
import javax.swing.JTextField;
import javax.swing.text.AttributeSet;
import javax.swing.text.BadLocationException;
import javax.swing.text.Document;
import javax.swing.text.DocumentFilter;
import javax.swing.text.PlainDocument;

public class DocFilter {
   public static void main(String[] args) {
      JTextField textField = new JTextField(10);

      JPanel panel = new JPanel();
      panel.add(textField);

      PlainDocument doc = (PlainDocument) textField.getDocument();
      doc.setDocumentFilter(new MyIntFilter());


      JOptionPane.showMessageDialog(null, panel);
   }
}

class MyIntFilter extends DocumentFilter {
   @Override
   public void insertString(FilterBypass fb, int offset, String string,
         AttributeSet attr) throws BadLocationException {

      Document doc = fb.getDocument();
      StringBuilder sb = new StringBuilder();
      sb.append(doc.getText(0, doc.getLength()));
      sb.insert(offset, string);

      if (test(sb.toString())) {
         super.insertString(fb, offset, string, attr);
      } else {
         // warn the user and don't allow the insert
      }
   }

   private boolean test(String text) {
      try {
         Integer.parseInt(text);
         return true;
      } catch (NumberFormatException e) {
         return false;
      }
   }

   @Override
   public void replace(FilterBypass fb, int offset, int length, String text,
         AttributeSet attrs) throws BadLocationException {

      Document doc = fb.getDocument();
      StringBuilder sb = new StringBuilder();
      sb.append(doc.getText(0, doc.getLength()));
      sb.replace(offset, offset + length, text);

      if (test(sb.toString())) {
         super.replace(fb, offset, length, text, attrs);
      } else {
         // warn the user and don't allow the insert
      }

   }

   @Override
   public void remove(FilterBypass fb, int offset, int length)
         throws BadLocationException {
      Document doc = fb.getDocument();
      StringBuilder sb = new StringBuilder();
      sb.append(doc.getText(0, doc.getLength()));
      sb.delete(offset, offset + length);

      if (test(sb.toString())) {
         super.remove(fb, offset, length);
      } else {
         // warn the user and don't allow the insert
      }

   }
}

Why is this important?

• What if the user uses copy and paste to insert data into the text component? A KeyListener can miss this?
• You appear to be desiring to check that the data can represent an int. What if they enter numeric data that doesn't fit?
• What if you want to allow the user to later enter double data? In scientific notation?

And if you want to put it into string within some text context, forget about + operator. Simply do:

// Qt 5 + C++11
auto i = 13;    
auto printable = QStringLiteral("My magic number is %1. That's all!").arg(i);

// Qt 5
int i = 13;    
QString printable = QStringLiteral("My magic number is %1. That's all!").arg(i);

// Qt 4
int i = 13;    
QString printable = QString::fromLatin1("My magic number is %1. That's all!").arg(i);

Convert .pem file to .ppk for Windows 10

You need to do following:

1. Download PuTTYGen with Pageant.
2. Press "load" button and select your ".pem" file.
3. Press "save private key" button and save your ".ppk" file.
4. Open Pageant and press "add key" button. Just all. Keep running Pageant in background.
5. Now login through SSH or SFTP without selecting password field.

Make a drawable file, striking_text.xml

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

layout xml

 <TextView
            ....
            ....
            android:background="@drawable/striking_text"
            android:foreground="@drawable/striking_text"
            android:text="69$"
           />

If your min SDK below API level 23 just use the background or just put the background and foreground in the Textview then the android studio will show an error that says create a layout file for API >23 after that remove the android:foreground="@drawable/stricking_text" from the main layout

Output look like this:

If you use Robert Harder's Base64 utility, then you can do:

InputStream is = new Base64.InputStream(cph);

Or with sun's JRE, you can do:

InputStream is = new
com.sun.xml.internal.messaging.saaj.packaging.mime.util.BASE64DecoderStream(cph)

However don't rely on that class continuing to be a part of the JRE, or even continuing to do what it seems to do today. Sun say not to use it.

There are other Stack Overflow questions about Base64 decoding, such as this one.

it appears that this also works

def normalizeRows(M):
    row_sums = M.sum(axis=1)
    return M / row_sums

You can check that theHref is defined by checking against undefined.

if (undefined !== theHref && theHref.length) {
    // `theHref` is not undefined and has truthy property _length_
    // do stuff
} else {
    // do other stuff
}

If you want to also protect yourself against falsey values like null then check theHref is truthy, which is a little shorter

if (theHref && theHref.length) {
    // `theHref` is truthy and has truthy property _length_
}

redirected uri is the location where the user will be redirected after successfully login to your app. for example to get access token for your app in facebook you need to subimt redirected uri which is nothing only the app Domain that your provide when you create your facebook app.

Use widget as PasswordInput

from django import forms
class UserForm(forms.ModelForm):
    password = forms.CharField(widget=forms.PasswordInput)
    class Meta:
        model = User

I always do it as below.

Use a single python file to config my log as singleton pattern which named 'log_conf.py'

#-*-coding:utf-8-*-

import logging.config

def singleton(cls):
    instances = {}
    def get_instance():
        if cls not in instances:
            instances[cls] = cls()
        return instances[cls]
    return get_instance()

@singleton
class Logger():
    def __init__(self):
        logging.config.fileConfig('logging.conf')
        self.logr = logging.getLogger('root')

In another module, just import the config.

from log_conf import Logger

Logger.logr.info("Hello World")

This is a singleton pattern to log, simply and efficiently.

You can also add 'active' class to the selected item.

$('.dropdown').on( 'click', '.dropdown-menu li a', function() { 
   var target = $(this).html();

   //Adds active class to selected item
   $(this).parents('.dropdown-menu').find('li').removeClass('active');
   $(this).parent('li').addClass('active');

   //Displays selected text on dropdown-toggle button
   $(this).parents('.dropdown').find('.dropdown-toggle').html(target + ' <span class="caret"></span>');
});

See the jsfiddle example

Correct syntax looks like this. See MSDN.

SELECT *
  FROM [FAEB].[dbo].[ExportaComisiones] AS f
  JOIN [zCredifiel].[dbo].[optPerson] AS p

  ON p.vTreasuryId COLLATE Latin1_General_CI_AS = f.RFC COLLATE Latin1_General_CI_AS 

v-model is for two way bindings means: if you change input value, the bound data will be changed and vice versa. But v-bind:value is called one way binding that means: you can change input value by changing bound data but you can't change bound data by changing input value through the element.

v-model is intended to be used with form elements. It allows you to tie the form element (e.g. a text input) with the data object in your Vue instance.

Example: https://jsfiddle.net/jamesbrndwgn/j2yb9zt1/1/

v-bind is intended to be used with components to create custom props. This allows you to pass data to a component. As the prop is reactive, if the data that’s passed to the component changes then the component will reflect this change

Example: https://jsfiddle.net/jamesbrndwgn/ws5kad1c/3/

Hope this helps you with basic understanding.

In PHP 5.3 or greater, you can get it like this:

$ip = getenv('HTTP_CLIENT_IP')?:
getenv('HTTP_X_FORWARDED_FOR')?:
getenv('HTTP_X_FORWARDED')?:
getenv('HTTP_FORWARDED_FOR')?:
getenv('HTTP_FORWARDED')?:
getenv('REMOTE_ADDR');

If you need both the sorted list and the list of indices, you could do:

L = [2,3,1,4,5]
from operator import itemgetter
indices, L_sorted = zip(*sorted(enumerate(L), key=itemgetter(1)))
list(L_sorted)
>>> [1, 2, 3, 4, 5]
list(indices)
>>> [2, 0, 1, 3, 4]

Or, for Python <2.4 (no itemgetter or sorted):

temp = [(v,i) for i,v in enumerate(L)]
temp.sort
indices, L_sorted = zip(*temp)

p.s. The zip(*iterable) idiom reverses the zip process (unzip).

Update:

To deal with your specific requirements:

"my specific need to sort a list of objects based on a property of the objects. i then need to re-order a corresponding list to match the order of the newly sorted list."

That's a long-winded way of doing it. You can achieve that with a single sort by zipping both lists together then sort using the object property as your sort key (and unzipping after).

combined = zip(obj_list, secondary_list)
zipped_sorted = sorted(combined, key=lambda x: x[0].some_obj_attribute)
obj_list, secondary_list = map(list, zip(*zipped_sorted))

Here's a simple example, using strings to represent your object. Here we use the length of the string as the key for sorting.:

str_list = ["banana", "apple", "nom", "Eeeeeeeeeeek"]
sec_list = [0.123423, 9.231, 23, 10.11001]
temp = sorted(zip(str_list, sec_list), key=lambda x: len(x[0]))
str_list, sec_list = map(list, zip(*temp))
str_list
>>> ['nom', 'apple', 'banana', 'Eeeeeeeeeeek']
sec_list
>>> [23, 9.231, 0.123423, 10.11001]

I'm using Rails 5 and the above answers work great; here's another way that also worked for me (the table name is :people and the column name is :email_address)

class AddIndexToEmailAddress < ActiveRecord::Migration[5.0]
  def change
    change_table :people do |t|
      t.index :email_address, unique: true
    end
  end
end

I would have done it like this. Short and sweet :)

Sub test()
Dim rngToSearch As Range
Dim FirstBlankCell As Range
Dim firstEmptyRow As Long

Set rngToSearch = Sheet1.Range("A:A")
    'Check first cell isn't empty
    If IsEmpty(rngToSearch.Cells(1, 1)) Then
        firstEmptyRow = rngToSearch.Cells(1, 1).Row
    Else
        Set FirstBlankCell = rngToSearch.FindNext(After:=rngToSearch.Cells(1, 1))
        If Not FirstBlankCell Is Nothing Then
            firstEmptyRow = FirstBlankCell.Row
        Else
            'no empty cell in range searched

            Else
                Set activeCell = FirstBlankCell
                FirstBlankRow = FirstBlankRow(rngToSearch, activeCell)

            End If
        Else
            'no empty cell in range searched
        End If
    End If
End Function

Try this and then tell me the results:

UPDATE File1 AS B                          
SET    b.campo1 = (SELECT DISTINCT A.campo1
                   FROM  File2 A           
                   INNER JOIN File1      
                   ON A.campo2 = File1.campo2 
                   AND A.campo2 = B.campo2) 

Just because this is what I got when I Googled this error, my problem was that I had

if (value < other.value)
  return -1;
else if (value >= other.value)
  return 1;
else
  return 0;

the value >= other.value should (obviously) actually be value > other.value so that you can actually return 0 with equal objects.

AFAIK, in the epic DOS era there is a header file named graphics.h shipped with Borland Turbo C++ suite. If it is true, then you are out of luck because we're now in Windows era.

I had the same problem yesterday. I solved it like this:

var obj = {
        foo:{},
        bar:{},
        baz:{}
    },
   first = null,
   key = null;
for (var key in obj) {
    first = obj[key];
    if(typeof(first) !== 'function') {
        break;
    }
}
// first is the first enumerated property, and key it's corresponding key.

Not the most elegant solution, and I am pretty sure that it may yield different results in different browsers (i.e. the specs says that enumeration is not required to enumerate the properties in the same order as they were defined). However, I only had a single property in my object so that was a non-issue. I just needed the first key.

default is basically const someVariableName

You don't need a named identifier because it's the default export for the file and you can name it whatever you want when you import it, so default is just condensing the variable assignment into a single keyword.

You can also try:

function getTagValue($string, $tag)
{
    $pattern = "/<{$tag}>(.*?)<\/{$tag}>/s";
    preg_match($pattern, $string, $matches);
    return isset($matches[1]) ? $matches[1] : '';
}

It returns empty string in case of no match.

jQuery.preferCulture("en-IN");
var price = jQuery.format(39.00, "c");

output is: Rs. 39.00

use jquery.glob.js,
    jQuery.glob.all.js

Following, in my opinion will solve the problem

1. Adding the init.py to your "~/Desktop/Python_Tutorials/diveintopython/py" folder
2. Go to Window --> Preferences --> PyDev --> Interpreters --> Python Interpreter to remove your Python Interpreter setting (reason being is because PyDev unable to auto refresh any updates made to any System PythonPath)
3. Add in the Interpreter with the same details as before (this will refresh your Python Interpreter setting with updates made to your PythonPath)
4. Finally since your "~/Desktop/Python_Tutorials/diveintopython/py" folder not a standard PythonPath, you will need to add it in. There are two ways to do it

a. As per what David German suggested. However this only applicable for the particular projects you are in b. Add in "~/Desktop/Python_Tutorials/diveintopython/py" into a new PythonPath under Window --> Preferences --> PyDev --> Interpreters --> Python Interpreter --> Libraries subtab --> NewFolder

Hope it helps.

This helped me:

bool fileExists = (System.IO.File.Exists(filePath) ? true : false);

You aren't actually sending JSON. You are passing an object as the data, but you need to stringify the object and pass the string instead.

Your dataType: "json" only tells jQuery that you want it to parse the returned JSON, it does not mean that jQuery will automatically stringify your request data.

Change to:

$.ajax({
        type: "POST",
        url: hb_base_url + "consumer",
        contentType: "application/json",
        dataType: "json",
        data: JSON.stringify({
            first_name: $("#namec").val(),
            last_name: $("#surnamec").val(),
            email: $("#emailc").val(),
            mobile: $("#numberc").val(),
            password: $("#passwordc").val()
        }),
        success: function(response) {
            console.log(response);
        },
        error: function(response) {
            console.log(response);
        }
});

If the data is actually a factor then you can use the levels() function, e.g.

levels( data$product_code )

If it's not a factor, but it should be, you can convert it to factor first by using the factor() function, e.g.

levels( factor( data$product_code ) )

Another option, as mentioned above, is the unique() function:

unique( data$product_code )

The main difference between the two (when applied to a factor) is that levels will return a character vector in the order of levels, including any levels that are coded but do not occur. unique will return a factor in the order the values first appear, with any non-occurring levels omitted (though still included in levels of the returned factor).

Another method is by using the menu within visual studio. Project -> Add Reference... I recommend copying the needed .dll to your resource folder, or local project folder.

Also, if, like me, you add controls directly in XAML (not using the editor), you might get frustrated that it won't stretch to the available height, even after setting those two properties.

To make the TextBox stretch, set the Height="Auto".

UPDATE:

In retrospect, I think this must have been necessary thanks to a default style for TextBoxes specifying the height to some standard for the application somewhere in the App resources. It may be worthwhile checking this if this helped you.

Default values cannot be supplied for parameters that are not declared 'optional'

 Function GetFindBooks(id As Integer, ByVal pid As Integer, Optional sort As String = "DESC", Optional limit As Integer = 99)

In your WebApiConfig

 config.Routes.MapHttpRoute( _
          name:="books", _
          routeTemplate:="api/{controller}/{action}/{id}/{pid}/{sort}/{limit}", _
          defaults:=New With {.id = RouteParameter.Optional, .pid = RouteParameter.Optional, .sort = UrlParameter.Optional, .limit = UrlParameter.Optional} _
      )

Use a div for your divider. It will always be centered vertically regardless to whether left and right divs are equal in height. You can reuse it anywhere on your site.

.divider{
    position:absolute;
    left:50%;
    top:10%;
    bottom:10%;
    border-left:1px solid white;
}

I switched from @Inject to @EJB because @EJB allows circular injection whereas @Inject pukes on it.

Details: I needed @PostConstruct to call an @Asynchronous method but it would do so synchronously. The only way to make the asynchronous call was to have the original call a method of another bean and have it call back the method of the original bean. To do this each bean needed a reference to the other -- thus circular. @Inject failed for this task whereas @EJB worked.

The functionality you cite is not standard Javascript, not likely to be portable across browsers and therefore not good practice. The ECMAScript 3 spec leaves the parse and output formats function up to the Javascript implementation. ECMAScript 5 adds a subset of ISO8601 support. I believe the toString() function you mention is an innovation in one browser (Mozilla?)

Several libraries provide routines to parameterize this, some with extensive localization support. You can also check out the methods in dojo.date.locale.

Place the full path to mvn in your PATH environment variable.

Go to Project Properties and under Build Make sure that the "Optimize Code" checkbox is unchecked.

Also, set the "Debug Info" dropdown to "Full" in the Advanced Options (Under Build tab).

I use it because VC++'s Intellisense can't tell when to show private members when accessing out of the class. The only indication is a little "lock" symbol on the field icon in the Intellisense list. It just makes it easier to identify private members(fields) easier. Also a habit from C# to be honest.

class Person {
   std::string m_Name;
public:
   std::string Name() { return m_Name; }
   void SetName(std::string name) { m_Name = name; }
};

int main() {
  Person *p = new Person();
  p->Name(); // valid
  p->m_Name; // invalid, compiler throws error. but intellisense doesn't know this..
  return 1;
}

when you see this problem always put your autocomplete function in keyup function and ensure you have added the libraries

$( "#searcharea" ).keyup(function(){
   $( "#searcharea" ).autocomplete({
      source: "suggestions.php"
   });
});

You use std::find from <algorithm>, which works equally well for std::list and std::vector. std::vector does not have its own search/find function.

#include <list>
#include <algorithm>

int main()
{
    std::list<int> ilist;
    ilist.push_back(1);
    ilist.push_back(2);
    ilist.push_back(3);

    std::list<int>::iterator findIter = std::find(ilist.begin(), ilist.end(), 1);
}

Note that this works for built-in types like int as well as standard library types like std::string by default because they have operator== provided for them. If you are using using std::find on a container of a user-defined type, you should overload operator== to allow std::find to work properly: EqualityComparable concept

Just add another variable.

int temp;
while (cin >> temp && V.size() < n){
    V.push_back(temp);
}

Binary floating point math is like this. In most programming languages, it is based on the IEEE 754 standard. The crux of the problem is that numbers are represented in this format as a whole number times a power of two; rational numbers (such as 0.1, which is 1/10) whose denominator is not a power of two cannot be exactly represented.

For 0.1 in the standard binary64 format, the representation can be written exactly as

• 0.1000000000000000055511151231257827021181583404541015625 in decimal, or
• 0x1.999999999999ap-4 in C99 hexfloat notation.

In contrast, the rational number 0.1, which is 1/10, can be written exactly as

• 0.1 in decimal, or
• 0x1.99999999999999...p-4 in an analogue of C99 hexfloat notation, where the ... represents an unending sequence of 9's.

The constants 0.2 and 0.3 in your program will also be approximations to their true values. It happens that the closest double to 0.2 is larger than the rational number 0.2 but that the closest double to 0.3 is smaller than the rational number 0.3. The sum of 0.1 and 0.2 winds up being larger than the rational number 0.3 and hence disagreeing with the constant in your code.

A fairly comprehensive treatment of floating-point arithmetic issues is What Every Computer Scientist Should Know About Floating-Point Arithmetic. For an easier-to-digest explanation, see floating-point-gui.de.

Side Note: All positional (base-N) number systems share this problem with precision

Plain old decimal (base 10) numbers have the same issues, which is why numbers like 1/3 end up as 0.333333333...

You've just stumbled on a number (3/10) that happens to be easy to represent with the decimal system, but doesn't fit the binary system. It goes both ways (to some small degree) as well: 1/16 is an ugly number in decimal (0.0625), but in binary it looks as neat as a 10,000th does in decimal (0.0001)** - if we were in the habit of using a base-2 number system in our daily lives, you'd even look at that number and instinctively understand you could arrive there by halving something, halving it again, and again and again.

** Of course, that's not exactly how floating-point numbers are stored in memory (they use a form of scientific notation). However, it does illustrate the point that binary floating-point precision errors tend to crop up because the "real world" numbers we are usually interested in working with are so often powers of ten - but only because we use a decimal number system day-to-day. This is also why we'll say things like 71% instead of "5 out of every 7" (71% is an approximation, since 5/7 can't be represented exactly with any decimal number).

So no: binary floating point numbers are not broken, they just happen to be as imperfect as every other base-N number system :)

Side Side Note: Working with Floats in Programming

In practice, this problem of precision means you need to use rounding functions to round your floating point numbers off to however many decimal places you're interested in before you display them.

You also need to replace equality tests with comparisons that allow some amount of tolerance, which means:

Do not do if (x == y) { ... }

Instead do if (abs(x - y) < myToleranceValue) { ... }.

where abs is the absolute value. myToleranceValue needs to be chosen for your particular application - and it will have a lot to do with how much "wiggle room" you are prepared to allow, and what the largest number you are going to be comparing may be (due to loss of precision issues). Beware of "epsilon" style constants in your language of choice. These are not to be used as tolerance values.

Set a session variable for every page on your site (actual pages not includes or rpcs) that contains the current page name, then in your Ajax call pass a nonce salted with the $_SERVER['SCRIPT_NAME'];

<?php
function create_nonce($optional_salt='')
{
    return hash_hmac('sha256', session_id().$optional_salt, date("YmdG").'someSalt'.$_SERVER['REMOTE_ADDR']);
}
$_SESSION['current_page'] = $_SERVER['SCRIPT_NAME'];
?>

<form>
  <input name="formNonce" id="formNonce" type="hidden" value="<?=create_nonce($_SERVER['SCRIPT_NAME']);?>">
  <label class="form-group">
    Login<br />
    <input name="userName" id="userName" type="text" />
  </label>
  <label class="form-group">
    Password<br />
    <input name="userPassword" id="userPassword" type="password" />
  </label>
  <button type="button" class="btnLogin">Sign in</button>
</form>
<script type="text/javascript">
    $("form.login button").on("click", function() {
        authorize($("#userName").val(),$("#userPassword").val(),$("#formNonce").val());
    });

    function authorize (authUser, authPassword, authNonce) {
        $.ajax({
          type: "POST",
          url: "/inc/rpc.php",
          dataType: "json",
          data: "userID="+authUser+"&password="+authPassword+"&nonce="+authNonce
        })
        .success(function( msg ) {
            //some successful stuff
        });
    }
</script>

Then in the rpc you are calling test the nonce you passed, if it is good then odds are pretty great that your rpc was legitimately called:

<?php
function check_nonce($nonce, $optional_salt='')
{
    $lasthour = date("G")-1<0 ? date('Ymd').'23' : date("YmdG")-1;
    if (hash_hmac('sha256', session_id().$optional_salt, date("YmdG").'someSalt'.$_SERVER['REMOTE_ADDR']) == $nonce || 
        hash_hmac('sha256', session_id().$optional_salt, $lasthour.'someSalt'.$_SERVER['REMOTE_ADDR']) == $nonce)
    {
        return true;
    } else {
        return false;
    }
}

$ret = array();
header('Content-Type: application/json');
if (check_nonce($_POST['nonce'], $_SESSION['current_page']))
{
    $ret['nonce_check'] = 'passed';
} else {
    $ret['nonce_check'] = 'failed';
}
echo json_encode($ret);
exit;
?>

edit: FYI the way I have it set the nonce is only good for an hour and change, so if they have not refreshed the page doing the ajax call in the last hour or 2 the ajax request will fail.

Windows consoles usually doesnt interpret double quotes correctly in a JSON array, so you can solve it adding a slash / before double quotes.

git reset --hard 4a155e5 Will move the HEAD back to where you want to be. There may be other references ahead of that time that you would need to remove if you don't want anything to point to the history you just deleted.

It has worked for me as follows.

ed1.requestFocus();

            return; //Faça um return para retornar o foco

A method i often use to scroll a container to its contents.

/**
@param {HTMLElement} container : element scrolled.
@param {HTMLElement} target : element where to scroll.
@param {number} [offset] : scroll back by offset
*/
var scrollAt=function(container,target,offset){
    if(container.contains(target)){
        var ofs=[0,0];
        var tmp=target;
        while (tmp!==container) {
            ofs[0]+=tmp.offsetWidth;
            ofs[1]+=tmp.offsetHeight;
            tmp=tmp.parentNode;
        }
        container.scrollTop = Math.max(0,ofs[1]-(typeof(offset)==='number'?offset:0));
    }else{
        throw('scrollAt Error: target not found in container');
    }
};

if your whish to override globally, you could also do :

HTMLElement.prototype.scrollAt=function(target,offset){
    if(this.contains(target)){
        var ofs=[0,0];
        var tmp=target;
        while (tmp!==this) {
            ofs[0]+=tmp.offsetWidth;
            ofs[1]+=tmp.offsetHeight;
            tmp=tmp.parentNode;
        }
        container.scrollTop = Math.max(0,ofs[1]-(typeof(offset)==='number'?offset:0));
    }else{
        throw('scrollAt Error: target not found in container');
    }
};

I had this problem before, and solved it according to React official page isMounted is an Antipattern.

Set a property isMounted flag to be true in componentDidMount , and toggle it false in componentWillUnmount. When you setState() in your callbacks, check isMounted first! It works for me.

state = {
    isMounted: false
  }
  componentDidMount() {
      this.setState({isMounted: true})
  }
  componentWillUnmount(){
      this.setState({isMounted: false})
  }

callback:

if (this.state.isMounted) {
 this.setState({'time': remainTimeInfo});}

You could implement a custom IEqualityComparer<Employee>:

public class Employee
{
    public string empName { get; set; }
    public string empID { get; set; }
    public string empLoc { get; set; }
    public string empPL { get; set; }
    public string empShift { get; set; }

    public class Comparer : IEqualityComparer<Employee>
    {
        public bool Equals(Employee x, Employee y)
        {
            return x.empLoc == y.empLoc
                && x.empPL == y.empPL
                && x.empShift == y.empShift;
        }

        public int GetHashCode(Employee obj)
        {
            unchecked  // overflow is fine
            {
                int hash = 17;
                hash = hash * 23 + (obj.empLoc ?? "").GetHashCode();
                hash = hash * 23 + (obj.empPL ?? "").GetHashCode();
                hash = hash * 23 + (obj.empShift ?? "").GetHashCode();
                return hash;
            }
        }
    }
}

Now you can use this overload of Enumerable.Distinct:

var distinct = employees.Distinct(new Employee.Comparer());

The less reusable, robust and efficient approach, using an anonymous type:

var distinctKeys = employees.Select(e => new { e.empLoc, e.empPL, e.empShift })
                            .Distinct();
var joined = from e in employees
             join d in distinctKeys
             on new { e.empLoc, e.empPL, e.empShift } equals d
             select e;
// if you want to replace the original collection
employees = joined.ToList();

In my Case Problem solved with Instant Run Disable in Android Studio 3.1.2

The solution comes from the display property.

Basically you need to make the two divs act like table cells. So instead of using float:left, you'll have to use display:table-cell on both divs, and for the dynamic width div you need to set width:auto; also. The both divs should be placed into a 100% width container with the display:table property.

Here is the css:

.container {display:table;width:100%}
#search {
  width: 160px;
  height: 25px;
  display:table-cell;
  background-color: #FFF;
}
#navigation {
  width: auto;
  display:table-cell;
  /*background-color: url('../images/transparent.png') ;*/
  background-color: #A53030;
}

*html #navigation {float:left;}

And the HTML:

<div class="container">
   <div id="search"></div>
   <div id="navigation"></div>
</div>

IMPORTANT:For Internet Explorer you need to specify the float property on the dynamic width div, otherwise the space will not be filled.

I hope that this will solve your problem. If you want, you can read the full article I wrote about this on my blog.

Followed Stephen's advice and tried to debug the code and whoa! it worked. The answer lies in the debug message itself.

Will attempt to recover by breaking constraint NSLayoutConstraint:0x191f0920 H:[MPKnockoutButton:0x17a876b0]-(34)-[MPDetailSlider:0x17a8bc50](LTR)>

The line above tells you that the runtime worked by removing this constraint. May be you don't need Horizontal Spacing on your button (MPKnockoutButton). Once you clear this constraint, it won't complain at runtime & you would get the desired behaviour.

if you have some other scripts that conflicts with jQuery wrap your code with this

(function($) {
    //here is your code
})(jQuery);

You can use the BeforeClass annotation:

@BeforeClass
public static void setUpClass() {
    //executed only once, before the first test
}

If your object is not polymorphic (and a stack implementation likely isn't), then as per other answers here, what you want is the copy constructor. Please note that there are differences between copy construction and assignment in C++; if you want both behaviors (and the default versions don't fit your needs), you'll have to implement both functions.

If your object is polymorphic, then slicing can be an issue and you might need to jump through some extra hoops to do proper copying. Sometimes people use as virtual method called clone() as a helper for polymorphic copying.

Finally, note that getting copying and assignment right, if you need to replace the default versions, is actually quite difficult. It is usually better to set up your objects (via RAII) in such a way that the default versions of copy/assign do what you want them to do. I highly recommend you look at Meyer's Effective C++, especially at items 10,11,12.

Make

if [ "$file" == "*.txt" ]

like this:

if [[ $file == *.txt ]]

That is, double brackets and no quotes.

The right side of == is a shell pattern. If you need a regular expression, use =~ then.

I would use:

public class Test {
    private static final Map<Integer, String> MY_MAP = createMap();

    private static Map<Integer, String> createMap() {
        Map<Integer, String> result = new HashMap<>();
        result.put(1, "one");
        result.put(2, "two");
        return Collections.unmodifiableMap(result);
    }
}

1. it avoids an anonymous class, which I personally consider to be a bad style, and avoid
2. it makes the creation of map more explicit
3. it makes map unmodifiable
4. as MY_MAP is constant, I would name it like constant

You need to have a doGet method as:

public void doGet(HttpServletRequest request,
        HttpServletResponse response)
throws IOException, ServletException
{
    response.setContentType("text/html");
    PrintWriter out = response.getWriter();

    out.println("<html>");
    out.println("<head>");
    out.println("<title>Hola</title>");
    out.println("</head>");
    out.println("<body bgcolor=\"white\">");
    out.println("</body>");
    out.println("</html>");
}

You can see this link for a simple hello world servlet

You can use TypeScript's native string interpolation in case if your only goal to eliminate ugly string concatenations and boring string conversions:

var yourMessage = `Your text ${yourVariable} your text continued ${yourExpression} and so on.`

NOTE:

At the right side of the assignment statement the delimiters are neither single or double quotes, instead a special char called backtick or grave accent.

The TypeScript compiler will translate your right side special literal to a string concatenation expression. With other words this syntax is not relies the ECMAScript 6 feature instead a native TypeScript feature. Your generated javascript code remains compatible.

You need a table variable:

declare @values table
(
    Value varchar(1000)
)

insert into @values values ('A')
insert into @values values ('B')
insert into @values values ('C')

select blah
from foo
where myField in (select value from @values)

i have alreay 2 situations where directives and services/factories didnt play well.

the scenario is that i have (had) a directive that has dependency injection of a service, and from the directive i ask the service to make an ajax call (with $http).

in the end, in both cases the ng-Repeat did not file at all, even when i gave the array an initial value.

i even tried to make a directive with a controller and an isolated-scope

only when i moved everything to a controller and it worked like magic.

example about this here Initialising jQuery plugin (RoyalSlider) in Angular JS

Alternatively you can use like this

var test = new Array();
test[0]={};
test[0]['a'] = 'test';
test[1]={};
test[1]['b'] = 'test b';
var json = JSON.stringify(test);
alert(json);

Like this you JSON-ing a array.

use this too :

if(e.preventDefault) 
   e.preventDefault(); 
else 
   e.returnValue = false;

Becoz e.preventDefault() is not supported in IE( some versions ). In IE it is e.returnValue = false

stage.getIcons().add(new Image(ClassLoader.getSystemResourceAsStream("images/icon.png")));

images folder need to be in Resource folder.

In my case I imported pyxlsd module before module wich works with db Mysql. After I did put Mysql module first(upper in code) it became to work like a clock. Think there was some namespace issue.

If you are trying to keep a list of lists (similar to python's list.append()) then this might work:

a <- list(1,2,3)
b <- list(4,5,6)
c <- append(list(a), list(b))

> c
[[1]]
[[1]][[1]]
[1] 1

[[1]][[2]]
[1] 2

[[1]][[3]]
[1] 3


[[2]]
[[2]][[1]]
[1] 4

[[2]][[2]]
[1] 5

[[2]][[3]]
[1] 6

using label with label text changed

<input type="file" id="files" name="files" class="hidden"/>
<label for="files" id="lable_file">Select file</label>

add jquery

<script>
     $("#files").change(function(){
        $("#lable_file").html($(this).val().split("\\").splice(-1,1)[0] || "Select file");     
     });
</script>

why not just pass an data an object with your key/value pairs then you don't have to worry about encoding

$.ajax({
    type: "Post",
    url: "getdata.php",
    data:{
       timestamp: timestamp,
       uid: id,
       uname: name
    },
    async: true,
    cache: false,
    success: function(data) {


    };
}?);?

In my case, I meet this problem that compile options in Android Studio is "stacktrace." Modify stacktrace to --stacktrace, the problem solved.

function dothis() {
  var x = document.getElementById("x").value;
  var index = document.getElementById("index").value;
  var text = document.getElementById("text").value;
  var length = document.getElementById("length").value;
  var arr = x.split("");
  arr.splice(index, length, text);
  var result = arr.join("");
  document.getElementById('output').innerHTML = result;
  console.log(result);
}
dothis();

<input id="x" type="text" value="White Dog" placeholder="Enter Text" />
<input id="index" type="number" min="0"value="6" style="width:50px" placeholder="index" />
<input id="length" type="number" min="0"value="1" style="width:50px" placeholder="length" />
<input id="text" type="text" value="F" placeholder="New character" />
<br>
<button id="submit" onclick="dothis()">Run</button>
<p id="output"></p>

This method is good for small length strings but may be slow for larger text.

var x = "White Dog";
var arr = x.split(""); // ["W", "h", "i", "t", "e", " ", "D", "o", "g"]
arr.splice(6, 1, 'F');

/* 
  Here 6 is starting index and 1 is no. of array elements to remove and 
  final argument 'F' is the new character to be inserted. 
*/
var result = arr.join(""); // "White Fog"

My status bar and navigation bar overlap after return from landscape view of YTPlayer. Here is my solution after trying @comonitos' version but not work on my iOS 8

- (void)fixNavigationBarPosition {
    if (self.navigationController) {
        CGRect frame = self.navigationController.navigationBar.frame;
        if (frame.origin.y != 20.f) {
            frame.origin.y = 20.f;
            self.navigationController.navigationBar.frame = frame;
        }
    }
}

Just call this function whenever you want to fix the position of navigation bar. I called on YTPlayerViewDelegate's playerView:didChangeToState:

- (void)playerView:(YTPlayerView *)playerView didChangeToState:(YTPlayerState)state {
    switch (state) {
        case kYTPlayerStatePaused:
        case kYTPlayerStateEnded:
            [self fixNavigationBarPosition];
            break;
        default:
    }
}

Well I had the same issue and tried "destroy" but that not worked for me. Then I found following work around My HTML was:

<input placeholder="Select Date" id="MyControlId" class="form-control datepicker" type="text" />

Jquery That work for me:

$('#MyControlId').data('datepicker').remove();

Here is another possible solution assuming matrix have one column( you can reshape original Mat to one column Mat via reshape):

Mat matrix= Mat::zeros(20, 1, CV_32FC1);
vector<float> vec;
matrix.col(0).copyTo(vec);

With dynamic allocation, using malloc:

int** x;

x = malloc(dimension1_max * sizeof(*x));
for (int i = 0; i < dimension1_max; i++) {
  x[i] = malloc(dimension2_max * sizeof(x[0]));
}

//Writing values
x[0..(dimension1_max-1)][0..(dimension2_max-1)] = Value; 
[...]

for (int i = 0; i < dimension1_max; i++) {
  free(x[i]);
}
free(x);

This allocates an 2D array of size dimension1_max * dimension2_max. So, for example, if you want a 640*480 array (f.e. pixels of an image), use dimension1_max = 640, dimension2_max = 480. You can then access the array using x[d1][d2] where d1 = 0..639, d2 = 0..479.

But a search on SO or Google also reveals other possibilities, for example in this SO question

Note that your array won't allocate a contiguous region of memory (640*480 bytes) in that case which could give problems with functions that assume this. So to get the array satisfy the condition, replace the malloc block above with this:

int** x;
int* temp;

x = malloc(dimension1_max * sizeof(*x));
temp = malloc(dimension1_max * dimension2_max * sizeof(x[0]));
for (int i = 0; i < dimension1_max; i++) {
  x[i] = temp + (i * dimension2_max);
}

[...]

free(temp);
free(x);

I use Composer-Setup.exe and it works fine. Just in case you need to know where is the composer.phar (to use with PhpStorm) :

Well, setTimeout is better in one situation, as I have just learned. I always use setInterval, which i have left to run in the background for more than half an hour. When i switched back to that tab, the slideshow (on which the code was used) was changing very rapidly, instead of every 5 seconds that it should have. It does in fact happen again as i test it more and whether it's the browser's fault or not isn't important, because with setTimeout that situation is completely impossible.

If you want to sort data either in Ascending or Descending order based on particular column, using sequlize js, use the order method of sequlize as follows

// Will order the specified column by descending order
order: sequelize.literal('column_name order')
e.g. order: sequelize.literal('timestamp DESC')

There are some problems with your code. First I advise to use parametrized queries so you avoid SQL Injection attacks and also parameter types are discovered by framework:

var cmd = new SqlCommand("SELECT EmpName FROM Employee WHERE EmpID = @id", con);
cmd.Parameters.AddWithValue("@id", id.Text);

Second, as you are interested only in one value getting returned from the query, it is better to use ExecuteScalar:

var name = cmd.ExecuteScalar();

if (name != null)
{
   position = name.ToString();
   Response.Write("User Registration successful");
}
else
{
    Console.WriteLine("No Employee found.");
}

The last thing is to wrap SqlConnection and SqlCommand into using so any resources used by those will be disposed of:

string position;

using (SqlConnection con = new SqlConnection("server=free-pc\\FATMAH; Integrated Security=True; database=Workflow; "))
{
  con.Open();

  using (var cmd = new SqlCommand("SELECT EmpName FROM Employee WHERE EmpID = @id", con))
  {
    cmd.Parameters.AddWithValue("@id", id.Text);
  
    var name = cmd.ExecuteScalar();
  
    if (name != null)
    {
       position = name.ToString();
       Response.Write("User Registration successful");
    }
    else
    {
        Console.WriteLine("No Employee found.");
    }
  }
}

Demo

Not sure if it is what you want, but just simple example:

var input = document.getElementById('input');

input.addEventListener("change", function() {
    var file  = this.files[0];
    var img = new Image();

    img.onload = function() {
        var sizes = {
            width:this.width,
            height: this.height
        };
        URL.revokeObjectURL(this.src);

        console.log('onload: sizes', sizes);
        console.log('onload: this', this);
    }

    var objectURL = URL.createObjectURL(file);

    console.log('change: file', file);
    console.log('change: objectURL', objectURL);
    img.src = objectURL;
});

What do you want to fade? The background or color attribute?

Currently you're changing the background color, but telling it to transition the color property. You can use all to transition all properties.

.clicker { 
    -moz-transition: all .2s ease-in;
    -o-transition: all .2s ease-in;
    -webkit-transition: all .2s ease-in;
    transition: all .2s ease-in;
    background: #f5f5f5; 
    padding: 20px;
}

.clicker:hover { 
    background: #eee;
}

Otherwise just use transition: background .2s ease-in.

An answer from AlexGo did the trick for me:

getActivity().runOnUiThread(new Runnable() {
        @Override
        public void run() {
         messages.add(m);
         adapter.notifyDataSetChanged();
         getListView().setSelection(messages.size()-1);
        }
});

List Update worked for me before when the update was triggered from a GUI event, thus being in the UI thread.

However, when I update the list from another event/thread - i.e. a call from outside the app, the update would not be in the UI thread and it ignored the call to getListView. Calling the update with runOnUiThread as above did the trick for me. Thanks!!

Seems a timestamp issue. According to tomcat documentation, if there is a new jsp or servlet this will create a new _java file in the work folder unless the _java.class files are newer than the jsp or servlets.

ID is an attribute, you can set it with the attr function:

$(element).attr('id', 'newID');

I'm not sure what you mean about adding IDs since an element can only have one identifier and this identifier must be unique.

This is your 2nd question: string.lowercase[ord('a')-97:ord('n')-97:2] because 97==ord('a') -- if you want to learn a bit you should figure out the rest yourself ;-)

You can use:

Integer grandChildCount = ((BigInteger) result[1]).intValue();

Or perhaps cast to Number to cover both Integer and BigInteger values.

as simple as that: echo '<a href="'.$link_address.'">Link</a>';

If your DBMS supports the notation, you need a separate set of parentheses for each row:

INSERT INTO Data(Col1) VALUES ('Hello'), ('World');

The cross-referenced question shows examples for inserting into two columns.

Alternatively, every SQL DBMS supports the notation using separate statements, one for each row to be inserted:

INSERT INTO Data (Col1) VALUES ('Hello');
INSERT INTO Data (Col1) VALUES ('World');

I would recommend keeping the object you have, and just utilizing the properties that you want, rather than removing the resolution you already have.

If you want to print it in a certain format you may want to look at this...That way you can preserve your resolution further down the line.

That being said you can create a new DateTime object using only the properties you want as @romkyns has in his answer.

A hacky way of doing JSON_UNESCAPED_UNICODE in PHP 5.3. Really disappointed by PHP json support. Maybe this will help someone else.

$array = some_json();
// Encode all string children in the array to html entities.
array_walk_recursive($array, function(&$item, $key) {
    if(is_string($item)) {
        $item = htmlentities($item);
    }
});
$json = json_encode($array);

// Decode the html entities and end up with unicode again.
$json = html_entity_decode($rson);

num=[3,2,3,5,5,3,7,6,4,6,7,2]
print ('\nelements are:\t',num)
count_dict={}
for elements in num:
    count_dict[elements]=num.count(elements)
print ('\nfrequency:\t',count_dict)

I hate PYTHONPATH. I find it brittle and annoying to set on a per-user basis (especially for daemon users) and keep track of as project folders move around. I would much rather set sys.path in the invoke scripts for standalone projects.

However sys.path.append isn't the way to do it. You can easily get duplicates, and it doesn't sort out .pth files. Better (and more readable): site.addsitedir.

And script.py wouldn't normally be the more appropriate place to do it, as it's inside the package you want to make available on the path. Library modules should certainly not be touching sys.path themselves. Instead, you'd normally have a hashbanged-script outside the package that you use to instantiate and run the app, and it's in this trivial wrapper script you'd put deployment details like sys.path-frobbing.

To repeat what I said in my comment to Mr. Skeet: we can represent 1/3, 1/9, 1/27, or any rational in decimal notation. We do it by adding an extra symbol. For example, a line over the digits that repeat in the decimal expansion of the number. What we need to represent decimal numbers as a sequence of binary numbers are 1) a sequence of binary numbers, 2) a radix point, and 3) some other symbol to indicate the repeating part of the sequence.

Hehner's quote notation is a way of doing this. He uses a quote symbol to represent the repeating part of the sequence. The article: http://www.cs.toronto.edu/~hehner/ratno.pdf and the Wikipedia entry: http://en.wikipedia.org/wiki/Quote_notation.

There's nothing that says we can't add a symbol to our representation system, so we can represent decimal rationals exactly using binary quote notation, and vice versa.

There are many other ways to accomplish this, I would do something like this.

I had to do this in .NET and I couldn't find any API's out there. My solution was to unzip the .xlsx, and dive right into manipulating the XML. It's not so bad once you create your helper classes and such.

There are some "gotchas" like the nodes all have to be sorted according to the way excel expects them, that I didn't find in the official docs. Excel has its own date timestamping, so you'll need to make a conversion formula.

if u want to set a bitmap object to image view here is simple two line`

Bitmap bitmap=BitmapFactory.decodeResource(getResources(),R.drawable.sample_drawable_image);
image.setImageBitmap(bitmap);

As paxdiablo said make -f pax.mk would execute the pax.mk makefile, if you directly execute it by typing ./pax.mk, then you would get syntax error.

Also you can just type make if your file name is makefile/Makefile.

Suppose you have two files named makefile and Makefile in the same directory then makefile is executed if make alone is given. You can even pass arguments to makefile.

This answer is for those of you looking to Install Bootstrap 3 in your Rails app without using a gem. There are two simple ways to do this that take less than 10 minutes. Pick the one that suites your needs best. Glyphicons and Javascript work and I've tested them with the latest beta of Rails 4.1.0 as well.

1. Using Bootstrap 3 with Rails 4 - The Bootstrap 3 files are copied into the vendor directory of your application.

2. Adding Bootstrap from a CDN to your Rails application - The Bootstrap 3 files are served from the Bootstrap CDN.

Number 2 above is the most flexible. All you need to do is change the version number that is stored in a layout helper. So you can run the Bootstrap version of your choice, whether that is 3.0.0, 3.0.3 or even older Bootstrap 2 releases.

ActiveSupport::OrderedHash is another option if you don't want to use ruby 1.9.2 or roll your own workarounds.

Looks like /e option is what you need, it'll skip same files/directories.

robocopy c:\data c:\backup /e

If you run the command twice, you'll see the second round is much faster since it skips a lot of things.

To undo git checkout do git checkout -, similarly to cd and cd - in shell.

I would use the built-in ngInclude directive. In the example below, you don't even need to write any javascript. The templates can just as easily live at a remote url.

If you're worried about changes and possibly incompatibly VMs, just copy the existing hashcode implementation into your own utility class, and use that to generate your hashcodes .

Use the re.escape() function for this:

4.2.3 re Module Contents

escape(string)

Return string with all non-alphanumerics backslashed; this is useful if you want to match an arbitrary literal string that may have regular expression metacharacters in it.

A simplistic example, search any occurence of the provided string optionally followed by 's', and return the match object.

def simplistic_plural(word, text):
    word_or_plural = re.escape(word) + 's?'
    return re.match(word_or_plural, text)

I was facing the same issue, and it drove me up the wall. The issue ended up to be that the .idea folder was ALREADY commited into the repo previously, and so they were being tracked by git regardless of whether you ignored them or not. I would recommend the following, after closing RubyMine/IntelliJ or whatever IDE you are using:

mv .idea ../.idea_backup
rm .idea # in case you forgot to close your IDE
git rm -r .idea 
git commit -m "Remove .idea from repo"
mv ../.idea_backup .idea

After than make sure to ignore .idea in your .gitignore

Although it is sufficient to ignore it in the repository's .gitignore, I would suggest that you ignore your IDE's dotfiles globally.

Otherwise you will have to add it to every .gitgnore for every project you work on. Also, if you collaborate with other people, then its best practice not to pollute the project's .gitignore with private configuation that are not specific to the source-code of the project.

You should use List or array instead

List<Integer> list = new ArrayList<Integer>();
list.add(1);
list.add(2);
list.add(3);

Or

int[] arr  = new int[10];
arr[0]=1;
arr[1]=2;

Or even better

Map<String, Integer> map = new HashMap<String, Integer>();
map.put("n1", 1);
map.put("n2", 2);

//conditionally get 
map.get("n1");

<?php
$start = strtotime("12:00");
$end = // Run query to get datetime value from db
$elapsed = $end - $start;
echo date("H:i", $elapsed);
?>

Yet another solution to get timezone offset:

TimeZone tz = TimeZone.getDefault();
String current_Time_Zone = getGmtOffsetString(tz.getRawOffset());

public static String getGmtOffsetString(int offsetMillis) {
    int offsetMinutes = offsetMillis / 60000;
    char sign = '+';
    if (offsetMinutes < 0) {
        sign = '-';
        offsetMinutes = -offsetMinutes;
    }
    return String.format("GMT%c%02d:%02d", sign, offsetMinutes/60, offsetMinutes % 60);
}

I have had the same problem in the past on many sites I have done here at work. The only guaranteed method of making sure the user gets the email is to advise the user to add you to there safe list. Any other method is really only going to be something that can help with it and isn't guaranteed.

I took the liberty to expand the answer from nona-urbiz; just add this to your ~/.bashrc:

git-pullall () { for RMT in $(git remote); do git pull -v $RMT $1; done; }    
alias git-pullall=git-pullall

git-pushall () { for RMT in $(git remote); do git push -v $RMT $1; done; }
alias git-pushall=git-pushall

Usage:

git-pullall master

git-pushall master ## or
git-pushall

If you do not provide any branch argument for git-pullall then the pull from non-default remotes will fail; left this behavior as it is, since it's analogous to git.

Also another difference is taking into consideration a situation where there is a skew join and you have to coalesce on top of it. A repartition will solve the skew join in most cases, then you can do the coalesce.

Another situation is, suppose you have saved a medium/large volume of data in a data frame and you have to produce to Kafka in batches. A repartition helps to collectasList before producing to Kafka in certain cases. But, when the volume is really high, the repartition will likely cause serious performance impact. In that case, producing to Kafka directly from dataframe would help.

side notes: Coalesce does not avoid data movement as in full data movement between workers. It does reduce the number of shuffles happening though. I think that's what the book means.

Please keep attention at this syntax:

* */6 * * *

This means 60 times (every minute) every 6 hours,

not

one time every 6 hours.

Check out this article. I believe it should help you get what you are wanting. If your table already exists, and it has data in it already, the error you are getting may be due to the auto_increment trying to assign a value that already exists for other records.

In short, as others have already mentioned in comments, sequences, as they are thought of and handled in Oracle, do not exist in MySQL. However, you can likely use auto_increment to accomplish what you want.

Without additional details on the specific error, it is difficult to provide more specific help.

UPDATE

CREATE TABLE ORD (
  ORDID INT NOT NULL AUTO_INCREMENT,
  //Rest of table code
  PRIMARY KEY (ordid)
)
AUTO_INCREMENT = 622;

This link is also helpful for describing usage of auto_increment. Setting the AUTO_INCREMENT value appears to be a table option, and not something that is specified as a column attribute specifically.

Also, per one of the links from above, you can alternatively set the auto increment start value via an alter to your table.

ALTER TABLE ORD AUTO_INCREMENT = 622;

UPDATE 2 Here is a link to a working sqlfiddle example, using auto increment.
I hope this info helps.

did all the above didn't work... may be some issue with NPM

One better way would be to use SELECT COUNT statement of SQL.

Just when you need the count of number of rows returned, execute another query returning the exact number of result of that query.

 try
{
   Conn=ConnectionODBC.getConnection();
   Statement stmt = Conn.createStatement();        
    String sqlStmt = sql;        
    String sqlrow = SELECT COUNT(*) from (sql) rowquery;
    String total = stmt.executeQuery(sqlrow);
    int rowcount = total.getInt(1);
    }

Now we have to use android.hardware.camera2 as android.hardware.Camera is deprecated which will only work on API >23 FlashLight

   public class MainActivity extends AppCompatActivity {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        button=(Button)findViewById(R.id.button);
        cameraManager = (CameraManager) 
        getSystemService(Context.CAMERA_SERVICE);
        try {
          cameraId = cameraManager.getCameraIdList()[0];
        } catch (CameraAccessException e) {
            e.printStackTrace();
        }
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if(light){
                    try {

                        cameraManager.setTorchMode(cameraId,true);
                    } catch (CameraAccessException e) {
                        e.printStackTrace();
                    }

                    light=false;}
                    else {

                    try {

                      cameraManager.setTorchMode(cameraId,false);
                    } catch (CameraAccessException e) {

                    light=true;
                    }


            }
        });
    }
}

If you have MFA enabled on GitLab you should go to Repository Settings/Repository ->Deploy Keys and create one, then use it as login while importing repo on GitHub

=IF(CR<=10, "RED", if(CR<50, "YELLOW", if(CR<101, "GREEN")))

CR = ColRow (Cell) This is an example. In this example when value in Cell is less then or equal to 10 then RED word will appear on that cell. In the same manner other if conditions are true if first if is false.

You should know more about java.lang.Math.max:

1. java.lang.Math.max(arg1,arg2) only accepts 2 arguments but you are writing 3 arguments in your code.
2. The 2 arguments should be double,int,long and float but your are writing String arguments in Math.max function. You need to parse them in the required type.

You code will produce compile time error because of above mismatches.

Try following updated code, that will solve your purpose:

import java.lang.Math;
import java.util.Scanner;
public class max {
    public static void main(String[] args) {
        Scanner keyboard = new Scanner(System.in);
        System.out.println("Please input 3 integers: ");
        int x = Integer.parseInt(keyboard.nextLine());
        int y = Integer.parseInt(keyboard.nextLine());
        int z = Integer.parseInt(keyboard.nextLine());
        int max = Math.max(x,y);
        if(max>y){ //suppose x is max then compare x with z to find max number
            max = Math.max(x,z);    
        }
        else{ //if y is max then compare y with z to find max number
            max = Math.max(y,z);    
        }
        System.out.println("The max of three is: " + max);
    }
} 

Use this package, it just works: https://github.com/jdunck/python-unicodecsv.

For all who are interested in a swift extension, this is what I'm using now:

extension UINavigationController {
    var rootViewController : UIViewController? {
        return self.viewControllers.first
    }
}

With the information you have provided, your best bet will be to use Python 3.x.

Your error suggests that the code may have been written for Python 3 given that it is trying to import urllib.parse. If you've written the software and have control over its source code, you should change the import to:

from urlparse import urlparse

urllib was split into urllib.parse, urllib.request, and urllib.error in Python 3.

I suggest that you take a quick look at software collections in CentOS if you are not able to change the imports for some reason. You can bring in Python 3.3 like this:

1. yum install centos­-release­-SCL
2. yum install python33
3. scl enable python33

First of all, You can verify this on your own by writing a simple TestCase!

empty Arraylist (with nulls as its items)

Second, If ArrayList is EMPTY that means it is really empty, it cannot have NULL or NON-NULL things as element.

Third,

 List list  = new ArrayList();
    list.add(null);
    System.out.println(list == null)

would print false.

Yield has two great uses,

1. It helps to provide custom iteration without creating temp collections.

2. It helps to do stateful iteration.

In order to explain above two points more demonstratively, I have created a simple video you can watch it here

You should use gnuplot and be sure to issue the command "set term dumb" after starting up. You can also give a row and column count. Here is the output from gnuplot if you issue "set term dumb 64 10" and then "plot sin(x)":

 

    1 ++-----------****-----------+--***-------+------****--++
  0.6 *+          **+  *          +**   *      sin(x)*******++
  0.2 +*         *      *         **     **         *     **++
    0 ++*       **       *       **       *       **       *++

It looks better at 79x24 (don't use the 80th column on an 80x24 display: some curses implementations don't always behave well around the last column).

I'm using gnuplot v4, but this should work on slightly older or newer versions.

Use git reflog to find the hashes of previously checked out commits.

A shortcut command to get to your last checked out branch (not sure if this work correctly with detached HEAD and intermediate commits though) is git checkout -

I know pretty well that this question have already been answered and that the OP is already happy with the accepted answer. But I found most of the answers, including the accepted one, to be a little bit more complicated.

I have a project which gave me a situation like this and I was able to achieve it this way.

First, you have to consider the casing of your enum names:

public enum AuthenticationMethod
{
    Forms = 1,
    WindowsAuthentication = 2,
    SingleSignOn = 3
}

Then, have this extension:

using System.Text.RegularExpression;

public static class AnExtension
{
    public static string Name(this Enum value)
    {
        string strVal = value.ToString();
        try
        {
            return Regex.Replace(strVal, "([a-z])([A-Z])", "$1 $2");
        }
        catch
        {
        }
        return strVal;
    }
}

Through this you can turn your every enum name to its string representation with each word separated with a space. Ex:

AuthenticationMethod am = AuthenticationMethod.WindowsAuthentication;
MessageBox.Show(am.Name());

As suggested in official docker document also. Try running this:

• sudo vi /etc/apt/sources.list

Then remove/comment any (deb [arch=amd64] https://download.docker.com/linux/ubuntu/ xenial stable) such entry at the last lines of the file.

Then in terminal run this command:

• sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu/ bionic stable"

• sudo apt-get update

It worked in my case.

Android BluetoothAdapter docs say it has been available since API Level 5. API Level 5 is Android 2.0.

You can try using a backport of the Bluetooth API (have not tried it personally): http://code.google.com/p/backport-android-bluetooth/

Brad Wilson has a couple great articles on unobtrusive validation and unobtrusive ajax.
It is also shown very nicely in this Pluralsight video in the section on " AJAX and JavaScript".

Basically, it is simply Javascript validation that doesn't pollute your source code with its own validation code. This is done by making use of data- attributes in HTML.

You need to use Range<String.Index> instead of the classic NSRange. The way I do it (maybe there is a better way) is by taking the string's String.Index a moving it with advance.

I don't know what range you are trying to replace, but let's pretend you want to replace the first 2 characters.

var start = textField.text.startIndex // Start at the string's start index
var end = advance(textField.text.startIndex, 2) // Take start index and advance 2 characters forward
var range: Range<String.Index> = Range<String.Index>(start: start,end: end)

textField.text.stringByReplacingCharactersInRange(range, withString: string)

In UTF-32 all of characters are coded with 32 bits. The advantage is that you can easily calculate the length of the string. The disadvantage is that for each ASCII characters you waste an extra three bytes.

In UTF-8 characters have variable length, ASCII characters are coded in one byte (eight bits), most western special characters are coded either in two bytes or three bytes (for example € is three bytes), and more exotic characters can take up to four bytes. Clear disadvantage is, that a priori you cannot calculate string's length. But it's takes lot less bytes to code Latin (English) alphabet text, compared to UTF-32.

UTF-16 is also variable length. Characters are coded either in two bytes or four bytes. I really don't see the point. It has disadvantage of being variable length, but hasn't got the advantage of saving as much space as UTF-8.

Of those three, clearly UTF-8 is the most widely spread.

See this answer. val() is comparing a string, not a numeric value.

The report says : a file is missing in ... vendor/win32-x64-48/binding.node

I looked for the binding.node file and I find it in...

https://github.com/sass/node-sass-binaries

Copy the correct file with the name binding.node and it works.

An array doesn't have an add method. You assign a value to an element of the array with num[i]=value;.

public static void main(String[] args) {
    int[] num = new int[args.length];
    for (int i=0; i < num.length; i++){
      int neki = Integer.parseInt(args[i]);
      num[i]=neki;
    }
}

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

extern "C" void foo();

I'm guessing that you don't need to re-increment the existing data so, why can't you just run a simple ALTER TABLE command to change the PK's attributes?

Something like:

ALTER TABLE `content` CHANGE `id` `id` SMALLINT( 5 ) UNSIGNED NOT NULL AUTO_INCREMENT 

I've tested this code on my own MySQL database and it works but I have not tried it with any meaningful number of records. Once you've altered the row then you need to reset the increment to a number guaranteed not to interfere with any other records.

ALTER TABLE `content` auto_increment = MAX(`id`) + 1

Again, untested but I believe it will work.

Since Java 7 there is factory method Locale.forLanguageTag and instance method Locale.toLanguageTag using IETF language tags.

In Oracle PL/SQL cursors will not result in table locks and it is possible to use bulk-collecting/bulk-fetching.

In Oracle 10 the often used implicit cursor

  for x in (select ....) loop
    --do something 
  end loop;

fetches implicitly 100 rows at a time. Explicit bulk-collecting/bulk-fetching is also possible.

However PL/SQL cursors are something of a last resort, use them when you are unable to solve a problem with set-based SQL.

Another reason is parallelization, it is easier for the database to parallelize big set-based statements than row-by-row imperative code. It is the same reason why functional programming becomes more and more popular (Haskell, F#, Lisp, C# LINQ, MapReduce ...), functional programming makes parallelization easier. The number CPUs per computer is rising so parallelization becomes more and more an issue.

The Liskov Substitution Principle

• The overridden method shouldn’t remain empty
• The overridden method shouldn’t throw an error
• Base class or interface behavior should not go for modification (rework) as because of derived class behaviors.

I've always heard them used in the opposite sense:

• & is the reference operator -- it gives you a reference (pointer) to some object

• * is the dereference operator -- it takes a reference (pointer) and gives you back the referred to object;

You need to use Integer.parseInt(String)

private void jTextField2MouseClicked(java.awt.event.MouseEvent evt) {
        if(evt.getSource()==jTextField2){
            int jml = Integer.parseInt(jTextField3.getText());
            jTextField1.setText(numberToWord(jml));

        }
    }

sometimes unchecked means other values, for instance checked could mean yes unchecked no or 0,1 etc it depends on the meaning you want to give.. so could be another state besides "unchecked means it's not in the querystring at all"

"It would make it a lot easier to store information in DB. Because then the number of fields from Serialize would equal the number of fields in table. Now I have to contrll which ones are missing", youre right this is my problem too... so it appears i have to check for this nonexisting value....

but maybe this could be a solution? http://tdanemar.wordpress.com/2010/08/24/jquery-serialize-method-and-checkboxes/

Basic on @Horyun Lee answer, I wrote a small python script to help to investigate ANR from traces.txt.

The ANRs will output as graphics by graphviz if you have installed grapvhviz on your system.

$ ./anr.py --format png ./traces.txt

A png will output like below if there are ANRs detected in file traces.txt. It's more intuitive.

The sample traces.txt file used above was get from here.

RStudio can handle markdown files and convert them into html and pdf. If you already have it, you can use RStudio (it is an IDE for R programming language). It is free and open source, and works on Windows, Mac and Linux.

Chart.js 2.0 has made this even easier.

You can find it under common chart configuration in the documentation. Should work on more then pie graphs.

options:{
    onClick: graphClickEvent
}

function graphClickEvent(event, array){
    if(array[0]){
        foo.bar; 
    }
}

It triggers on the entire chart, but if you click on a pie the model of that pie including index which can be used to get the value.

Please! please! please! DO NOT serialize data and place it into your database. Serialize can be used that way, but that's missing the point of a relational database and the datatypes inherent in your database engine. Doing this makes data in your database non-portable, difficult to read, and can complicate queries. If you want your application to be portable to other languages, like let's say you find that you want to use Java for some portion of your app that it makes sense to use Java in, serialization will become a pain in the buttocks. You should always be able to query and modify data in the database without using a third party intermediary tool to manipulate data to be inserted.

it makes really difficult to maintain code, code with portability issues, and data that is it more difficult to migrate to other RDMS systems, new schema, etc. It also has the added disadvantage of making it messy to search your database based on one of the fields that you've serialized.

That's not to say serialize() is useless. It's not... A good place to use it may be a cache file that contains the result of a data intensive operation, for instance. There are tons of others... Just don't abuse serialize because the next guy who comes along will have a maintenance or migration nightmare.

A good example of serialize() and unserialize() could be like this:

$posts = base64_encode(serialize($_POST));
header("Location: $_SERVER[REQUEST_URI]?x=$posts");

Unserialize on the page

if($_GET['x']) {
   // unpack serialize and encoded URL
   $_POST = unserialize(base64_decode($_GET['x']));
}

Variables in php are case sensitive. Please replace your while loop with following:

while ($rows = mysql_fetch_array($query)):

           $name = $rows['Name'];
           $address = $rows['Address'];
           $email = $rows['Email'];
           $subject = $rows['Subject'];
           $comment = $rows['Comment']

           echo "$name<br>$address<br>$email<br>$subject<br>$comment<br><br>";

           endwhile;

the accepted answer works but some of the used methods are now deprecated so I think it is best if I answer this question with updated methods.

this is answer is completely from this guide on google developers

so here is step by step guide:

1. implement all this in your map activity

   MapActivity extends FragmentActivity implements OnMapReadyCallback, GoogleApiClient.OnConnectionFailedListener, GoogleApiClient.ConnectionCallbacks

2. in your onCreate:

   private GoogleMap mMap;
   private Context context;
   private TextView txtStartPoint,txtEndPoint;
   private GoogleApiClient mGoogleApiClient;
   private Location mLastKnownLocation;
   private LatLng mDefaultLocation;
   private CameraPosition mCameraPosition;
   private boolean mLocationPermissionGranted;
   
   @Override
   protected void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);
   setContentView(R.layout.activity_maps);
   context = this;
   mGoogleApiClient = new GoogleApiClient.Builder(this)
           .enableAutoManage(this /* FragmentActivity */,
                   this /* OnConnectionFailedListener */)
           .addConnectionCallbacks(this)
           .addApi(LocationServices.API)
           .addApi(Places.GEO_DATA_API)
           .addApi(Places.PLACE_DETECTION_API)
           .build();
   mGoogleApiClient.connect();
   }
   

3. in your onConnected :

   SupportMapFragment mapFragment = (SupportMapFragment)     getSupportFragmentManager()
           .findFragmentById(map);
   mapFragment.getMapAsync(this);
   

4. in your onMapReady :

   @Override
   public void onMapReady(GoogleMap googleMap) {
   mMap = googleMap;
   
   // Do other setup activities here too, as described elsewhere in this tutorial.
   
   // Turn on the My Location layer and the related control on the map.
   updateLocationUI();
   
   // Get the current location of the device and set the position of the map.
   getDeviceLocation();
   }
   

5. and these two are methods in onMapReady :

   private void updateLocationUI() {
     if (mMap == null) {
       return;
   }
   
   if (ContextCompat.checkSelfPermission(this.getApplicationContext(),
           android.Manifest.permission.ACCESS_FINE_LOCATION)
           == PackageManager.PERMISSION_GRANTED) {
       mLocationPermissionGranted = true;
   }
   
   if (mLocationPermissionGranted) {
       mMap.setMyLocationEnabled(true);
       mMap.getUiSettings().setMyLocationButtonEnabled(true);
   } else {
       mMap.setMyLocationEnabled(false);
       mMap.getUiSettings().setMyLocationButtonEnabled(false);
       mLastKnownLocation = null;
   }
   }
   
   private void getDeviceLocation() {
   if (ContextCompat.checkSelfPermission(this.getApplicationContext(),
           android.Manifest.permission.ACCESS_FINE_LOCATION)
           == PackageManager.PERMISSION_GRANTED) {
       mLocationPermissionGranted = true;
   }
   
   if (mLocationPermissionGranted) {
       mLastKnownLocation = LocationServices.FusedLocationApi
               .getLastLocation(mGoogleApiClient);
   }
   
   // Set the map's camera position to the current location of the device.
   float DEFAULT_ZOOM = 15;
   if (mCameraPosition != null) {

this is very fast , smooth and effective. hope this helps

A sha256 is 256 bits long -- as its name indicates.

Since sha256 returns a hexadecimal representation, 4 bits are enough to encode each character (instead of 8, like for ASCII), so 256 bits would represent 64 hex characters, therefore you need a varchar(64), or even a char(64), as the length is always the same, not varying at all.

And the demo :

$hash = hash('sha256', 'hello, world!');
var_dump($hash);

Will give you :

$ php temp.php
string(64) "68e656b251e67e8358bef8483ab0d51c6619f3e7a1a9f0e75838d41ff368f728"

i.e. a string with 64 characters.

I agree with the majority view that external stylesheets are the prefered method.

However, here are some practical exceptions:

• Dynamic background images. CSS stylesheets are static files so you need to use an inline style to add a dynamic (from a database, CMS etc...) background-image style.

• If an element needs to be hidden when the page loads, using an external stylesheet for this is not practical, since there will always be some delay before the stylesheet is processed and the element will be visible until that happens. style="display: none;" is the best way to achieve this.

• If an application is going to give the user fine control over a particular CSS value, e.g. text color, then it may be necessary to add this to inline style elements or in-page <style></style> blocks. E.g. style="color:#{{ page.color }}", or <style> p.themed { color: #{{ page.color }}; }</style>

.Split(new string[] { "is Marco and" }, StringSplitOptions.None)

Consider the spaces surronding "is Marco and". Do you want to include the spaces in your result, or do you want them removed? It's quite possible that you want to use " is Marco and " as separator...

You could use a variable to make the calculation and use toFixed when you set the #diskamountUnit element value:

var amount = $("#disk").slider("value") * 1.60;
$("#diskamountUnit").val('$' + amount.toFixed(2));

You can also do that in one step, in the val method call but IMO the first way is more readable:

$("#diskamountUnit").val('$' + ($("#disk").slider("value") * 1.60).toFixed(2));

The following reads a file passed as an argument line by line:

while IFS= read -r line; do
    echo "Text read from file: $line"
done < my_filename.txt

This is the standard form for reading lines from a file in a loop. Explanation:

• IFS= (or IFS='') prevents leading/trailing whitespace from being trimmed.
• -r prevents backslash escapes from being interpreted.

Or you can put it in a bash file helper script, example contents:

#!/bin/bash
while IFS= read -r line; do
    echo "Text read from file: $line"
done < "$1"

If the above is saved to a script with filename readfile, it can be run as follows:

chmod +x readfile
./readfile filename.txt

If the file isn’t a standard POSIX text file (= not terminated by a newline character), the loop can be modified to handle trailing partial lines:

while IFS= read -r line || [[ -n "$line" ]]; do
    echo "Text read from file: $line"
done < "$1"

Here, || [[ -n $line ]] prevents the last line from being ignored if it doesn't end with a \n (since read returns a non-zero exit code when it encounters EOF).

If the commands inside the loop also read from standard input, the file descriptor used by read can be chanced to something else (avoid the standard file descriptors), e.g.:

while IFS= read -r -u3 line; do
    echo "Text read from file: $line"
done 3< "$1"

(Non-Bash shells might not know read -u3; use read <&3 instead.)

The equivalent is a BIT field.

In SQL you use 0 and 1 to set a bit field (just as a yes/no field in Access). In Management Studio it displays as a false/true value (at least in recent versions).

When accessing the database through ASP.NET it will expose the field as a boolean value.

Use the CLIM function (equivalent to CAXIS function in MATLAB):

plt.pcolor(X, Y, v, cmap=cm)
plt.clim(-4,4)  # identical to caxis([-4,4]) in MATLAB
plt.show()

One reason why your scripts could be loading so slowly is if you were running all of your scripts while loading the page, like this:

callMyFunctions();

instead of:

$(window).load(function() {
      callMyFunctions();
});

This second bit of script waits until the browser has completely loaded all of your Javascript code before it starts executing any of your scripts, making it appear to the user that the page has loaded faster.

If you're looking to enhance the user's experience by decreasing the loading time, I wouldn't go for the "loading screen" option. In my opinion that would be much more annoying than just having the page load more slowly.

One difference that's not at the language level but the popular implementation level: certain versions of gcc will remove unreferenced static inline functions from output by default, but will keep plain static functions even if unreferenced. I'm not sure which versions this applies to, but from a practical standpoint it means it may be a good idea to always use inline for static functions in headers.

I use this too:

System.Web.HTTPContext.Current.Server.MapPath

The following are some comparisons:

String s1 = "Hello";
String s2 = "Hello";
String s3 = new String("Hello");

System.out.println(s1 == s2); //true
System.out.println(s1.equals(s2)); //true

System.out.println(s1 == s3);   //false
System.out.println(s1.equals(s3)); //true

s3 = s3.intern();
System.out.println(s1 == s3); //true
System.out.println(s1.equals(s3)); //true

When intern() is called the reference is changed.

getdate() 

is the direct equivalent, but you should always use UTC datetimes

getutcdate()

whether your app operates across timezones or not - otherwise you run the risk of screwing up date math at the spring/fall transitions

To remove a timezone (tzinfo) from a datetime object:

# dt_tz is a datetime.datetime object
dt = dt_tz.replace(tzinfo=None)

If you are using a library like arrow, then you can remove timezone by simply converting an arrow object to to a datetime object, then doing the same thing as the example above.

# <Arrow [2014-10-09T10:56:09.347444-07:00]>
arrowObj = arrow.get('2014-10-09T10:56:09.347444-07:00')

# datetime.datetime(2014, 10, 9, 10, 56, 9, 347444, tzinfo=tzoffset(None, -25200))
tmpDatetime = arrowObj.datetime

# datetime.datetime(2014, 10, 9, 10, 56, 9, 347444)
tmpDatetime = tmpDatetime.replace(tzinfo=None)

Why would you do this? One example is that mysql does not support timezones with its DATETIME type. So using ORM's like sqlalchemy will simply remove the timezone when you give it a datetime.datetime object to insert into the database. The solution is to convert your datetime.datetime object to UTC (so everything in your database is UTC since it can't specify timezone) then either insert it into the database (where the timezone is removed anyway) or remove it yourself. Also note that you cannot compare datetime.datetime objects where one is timezone aware and another is timezone naive.

##############################################################################
# MySQL example! where MySQL doesn't support timezones with its DATETIME type!
##############################################################################

arrowObj = arrow.get('2014-10-09T10:56:09.347444-07:00')

arrowDt = arrowObj.to("utc").datetime

# inserts datetime.datetime(2014, 10, 9, 17, 56, 9, 347444, tzinfo=tzutc())
insertIntoMysqlDatabase(arrowDt)

# returns datetime.datetime(2014, 10, 9, 17, 56, 9, 347444)
dbDatetimeNoTz = getFromMysqlDatabase()

# cannot compare timzeone aware and timezone naive
dbDatetimeNoTz == arrowDt # False, or TypeError on python versions before 3.3

# compare datetimes that are both aware or both naive work however
dbDatetimeNoTz == arrowDt.replace(tzinfo=None) # True

Here it is:

select player_name, player_salary, (player_salary * 1.1) as player_newsalary
from player 
order by player_name, player_salary, player_newsalary desc

You don't need to "group by" if there is only one instance of a player in the table.

It seems in general you're just looking for a join:

> dat1 = pd.DataFrame({'dat1': [9,5]})
> dat2 = pd.DataFrame({'dat2': [7,6]})
> dat1.join(dat2)
   dat1  dat2
0     9     7
1     5     6

This question came first on Google although an old one so I'm posting the working answer I found, which can be of use to someone else.

This requires 3 divs including the fixed div.

HTML

<div class="wrapper">
    <div class="parent">
        <div class="child"></div>
    </div>
</div>

CSS

.wrapper { position:relative; width:1280px; }
    .parent { position:absolute; }
        .child { position:fixed; width:960px; }

You need to use parentheses: myList.insert([1, 2, 3]). When you leave out the parentheses, python thinks you are trying to access myList.insert at position 1, 2, 3, because that's what brackets are used for when they are right next to a variable.

Indeed, thanks to the comments to my post here, it looks like sparse directories are the way to go. I believe the following should do it:

svn checkout --depth empty http://svnserver/trunk/proj
svn update --set-depth infinity proj/foo
svn update --set-depth infinity proj/bar
svn update --set-depth infinity proj/baz

Alternatively, --depth immediates instead of empty checks out files and directories in trunk/proj without their contents. That way you can see which directories exist in the repository.

As mentioned in @zigdon's answer, you can also do a non-recursive checkout. This is an older and less flexible way to achieve a similar effect:

svn checkout --non-recursive http://svnserver/trunk/proj
svn update trunk/foo
svn update trunk/bar
svn update trunk/baz

You have to give the dictionary a type

// empty dict with Ints as keys and Strings as values
var namesOfIntegers = Dictionary<Int, String>()

If the compiler can infer the type, you can use the shorter syntax

namesOfIntegers[16] = "sixteen"
// namesOfIntegers now contains 1 key-value pair
namesOfIntegers = [:]
// namesOfIntegers is once again an empty dictionary of type Int, String

Since I didn't have the uninstaller listed - the solution turned out to be to reinstall Anaconda and then uninstall it.

I was also facing the same issue until I added the type="module" to the script.

Before it was like this

<script src="../src/main.js"></script>

And after changing it to

<script type="module" src="../src/main.js"></script>

It worked perfectly.

Issue:

.Net application code aborts before it starts its execution [Console application or Windows application]

Error received: Aborted with Error code "E0434352"

Exception: Unknown exception

Scenario 1:

When an application is already executed, which have used some of the dependent resources and those resources are still in use with the application executed, when another application or the same exe is triggered from some other source then one of the app throws the error

Scenario 2:

When an application is triggered by scheduler or automatic jobs, it may be in execution state at background, meanwhile when you try to trigger the same application again, the error may be triggered.

Solution:

Create an application, when & where the application release all its resources as soon as completed Kill all the background process once the application is closed Check and avoid executing the application from multiple sources like Batch Process, Task Scheduler and external tools at same time. Check for the Application and resource dependencies and clean up the code if needed.

Yes. The sequence doesn't have the 54th item.
