I've had various problems (see below) installing upgraded SSL modules, even inside a virtualenv, on top of older OS-provided Python versions, so I now use pyenv.

pyenv makes it very easy to install new Python versions and supports virtualenvs. Getting started is much easier than the recipes for virtualenv listed in other answers:

• On Mac, type brew install pyenv and on Linux, use pyenv-installer
• this gets you built-in virtualenv support as well as Python version switching (if required)
• works well with Python 2 or 3, can have many versions installed at once

This works very well to insulate the "new Python" version and virtualenv from system Python. Because you can easily use a more recent Python (post 2.7.9), the SSL modules are already upgraded, and of course like any modern virtualenv setup you are insulated from the system Python modules.

A couple of nice tutorials:

• Using pyenv and virtualenv - when selecting a Python version, it's easier to use pyenv global 3.6.1 (global to current user) or pyenv local 2.7.13 (local to current directory).
• pyenv basics and use with virtualenv

The pyenv-virtualenv plugin is now built in - type pyenv commands | grep virtualenv to check. I wouldn't use the pyenv-virtualenvwrapper plugin to start with - see how you get on with pyenv-virtualenv which is more integrated into pyenv, as this covers most of what virtualenvwrapper does.

pyenv is modelled on rbenv (a good tool for Ruby version switching) and its only dependency is bash.

• pyenv is unrelated to the very similarly named pyvenv - that is a virtualenv equivalent that's part of recent Python 3 versions, and doesn't handle Python version switching

Caveats

Two warnings about pyenv:

1. It only works from a bash or similar shell - or more specifically, the pyenv-virtualenv plugin doesn't like dash, which is /bin/sh on Ubuntu or Debian.
2. It must be run from an interactive login shell (e.g. bash --login using a terminal), which is not always easy to achieve with automation tools such as Ansible.

Hence pyenv is best for interactive use, and less good for scripting servers.

Older distributions - SSL module problems

One reason to use pyenv was that there were often problems with upgrading Python SSL modules when using older system-provided Python versions. This may be less of a problem now that current Linux distributions support Python 3.x.

On absolute or fixed elements you could also use z-index:

.item {
    position: absolute;
    z-index: -100;
}

.item:hover {
    z-index: 100;
}

Other elements should have a z-index between -100 and 100 now.

Taken from Burhan Khalid's answer and his comment about migrations: what worked for me was removing the content of the "migrations" folder along with the database, and then running manage.py migrate. Removing the database is not enough because of the saved information about table structure in the migrations folder.

You need to use ECHO. Also, put the quotes around the entire file path if it contains spaces.

One other note, use > to overwrite a file if it exists or create if it does not exist. Use >> to append to an existing file or create if it does not exist.

Overwrite the file with a blank line:

ECHO.>"C:\My folder\Myfile.log"

Append a blank line to a file:

ECHO.>>"C:\My folder\Myfile.log"

Append text to a file:

ECHO Some text>>"C:\My folder\Myfile.log"

Append a variable to a file:

ECHO %MY_VARIABLE%>>"C:\My folder\Myfile.log"

I don't think you need to change the MaxPermSize to 1024m. This works for me:

-startup
plugins/org.eclipse.equinox.launcher_1.0.200.v20090520.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.0.200.v20090519
-product
org.eclipse.epp.package.jee.product
--launcher.XXMaxPermSize
256M
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Xms256m
-Xmx1024m
-XX:PermSize=64m
-XX:MaxPermSize=128m

Verify the following steps.

1. Did you include jquery
2. Check for errors in firebug

Those things should fix the problem

Here is how I did it using only the default bootstrap CSS v3.3.1:

<div class="form-group">
    <label class="control-label">Start:</label>
    <div class="input-group">
        <input type="text" class="form-control" aria-describedby="start-date">
        <span class="input-group-addon" id="start-date"><span class="glyphicon glyphicon-calendar"></span></span>
    </div>
</div>

And this is how it looks:

Python’s raw strings are just a way to tell the Python interpreter that it should interpret backslashes as literal slashes. If you read strings entered by the user, they are already past the point where they could have been raw. Also, user input is most likely read in literally, i.e. “raw”.

This means the interpreting happens somewhere else. But if you know that it happens, why not escape the backslashes for whatever is interpreting it?

s = s.replace("\\", "\\\\")

(Note that you can't do r"\" as “a raw string cannot end in a single backslash”, but I could have used r"\\" as well for the second argument.)

If that doesn’t work, your user input is for some arcane reason interpreting the backslashes, so you’ll need a way to tell it to stop that.

Check if your image data contains some header information at the beginning:

imageCode = "data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAMgAAABkC...

This will cause the above error.

Just remove everything in front of and including the first comma, and you good to go.

imageCode = "iVBORw0KGgoAAAANSUhEUgAAAMgAAABkC...

You can add a sequence of numbers very easily with

data$ID <- seq.int(nrow(data))

If you are already using library(tidyverse), you can use

data <- tibble::rowid_to_column(data, "ID")

To get the value of cell, use the following syntax,

datagridviewName(columnFirst, rowSecond).value

But the intellisense and MSDN documentation is wrongly saying rowFirst, colSecond approach...

Whenever you are using require_once() can be use in a file to include another file when you need the called file only a single time in the current file. Here in the example I have an test1.php.

<?php  
echo "today is:".date("Y-m-d");  
?>  

and in another file that I have named test2.php

<?php  
require_once('test1.php');  
require_once('test1.php');  
?>

as you are watching the m requiring the the test1 file twice but the file will include the test1 once and for calling at the second time this will be ignored. And without halting will display the output a single time.

Whenever you are using 'include_once()` can be used in a file to include another file when you need the called file more than once in the current file. Here in the example I have a file named test3.php.

<?php  
echo "today is:".date("Y-m-d");  
?> 

And in another file that I have named test4.php

<?php  
include_once('test3.php');  
include_once('test3.php');  
?>

as you are watching the m including the test3 file will include the file a single time but halt the further execution.

Try this variation:

$(".tr_clone_add").live('click', CloneRow);

function CloneRow()
{
    $(this).closest('.tr_clone').clone().insertAfter(".tr_clone:last");
}

You can also try this

<li><%= link_to "", application_welcome_path, class: "navbar-brand metas-logo"    %></li>

Where "metas-logo" is a css class with a background image

You can also use stack()

df= DataFrame([list(range(5))], columns = [“a{}”.format(I) for I in range(5)])

After u run df, then run:

df.stack()

You obtain your dataframe in series

For a concrete example of accessing the SMS/MMS database, take a look at gTalkSMS.

The default git plugin for Jenkins does the job quite nicely.

After adding a new git repository (project configuration > Source Code Management > check the GIT option) to the project navigate to the bottom of the plugin settings, just above Repository browser region. There should be an Advanced button. After clicking it a new form should appear, with a value described as Local subdirectory for repo (optional). Setting this to folder will make the plugin to check out the repository into the folder relative to your workspace. This way you can have as many repositories in your project as you need, all in separate locations.

Alternatively, if the project you're using will allow that, you can use GIT sub modules, which are similar to external paths in SVN. In the GIT Book there is a section on that very topic. If that will not be against some policy, submodules are fairly simple to use, giving you powerful way to control the locations, versions/tags/branches that will be imported AND it will be available on your local repository as well giving you better portability.

Obviously the GIT plugin supports checking out submodules, so Jenkins can work with them quite effectively.

a = Array.new(Array.new(4))

0.upto(a.length-1) do |i|
  0.upto(a.length-1) do |j|
    a[i[j]] = 1
  end
end

0.upto(a.length-1) do |i|
  0.upto(a.length-1) do |j|
    print a[i[j]] = 1 #It's not a[i][j], but a[i[j]]
  end
  puts "\n"
end

or you can use the following to compile the all java source files in current directory..

javac *.java

Only set the IsEditable attribute to true

<ComboBox Name="comboBox1"            
          Text="--Select Team--"
          IsEditable="true"  <---- that's all!
          IsReadOnly="true"/>

I'm not sure if you want to find duplicate files or just compare two single files. If the latter, the above approach (filecmp) is better, if the former, the following approach is better.

There are lots of duplicate files detection questions here. Assuming they are not very small and that performance is important, you can

• Compare file sizes first, discarding all which doesn't match
• If file sizes match, compare using the biggest hash you can handle, hashing chunks of files to avoid reading the whole big file

Here's is an answer with Python implementations (I prefer the one by nosklo, BTW)

Here is a VB.NET solution based on ShravankumarKumar's solution.

This will ONLY give you the text. The images are a different story.

Public Shared Function GetTextFromPDF(PdfFileName As String) As String
    Dim oReader As New iTextSharp.text.pdf.PdfReader(PdfFileName)

    Dim sOut = ""

    For i = 1 To oReader.NumberOfPages
        Dim its As New iTextSharp.text.pdf.parser.SimpleTextExtractionStrategy

        sOut &= iTextSharp.text.pdf.parser.PdfTextExtractor.GetTextFromPage(oReader, i, its)
    Next

    Return sOut
End Function

The important thing is that the icon you want to be displayed as the application icon ( in the title bar and in the task bar ) must be the FIRST icon in the resource script file

The file is in the res folder and is named (applicationName).rc

/////////////////////////////////////////////////////////////////////////////
//
// Icon
//

// Icon with lowest ID value placed first to ensure application icon
// remains consistent on all systems.
(icon ID )          ICON                    "res\\filename.ico"

NestedScrollView is just like ScrollView, but in NestedScrollView we can put other scrolling views as child of it, e.g. RecyclerView.

But if we put RecyclerView inside NestedScrollView, RecyclerView's smooth scrolling is disturbed. So to bring back smooth scrolling there's trick:

ViewCompat.setNestedScrollingEnabled(recyclerView, false);

put above line after setting adapter for recyclerView.

Generally

Your pkl file is, in fact, a serialized pickle file, which means it has been dumped using Python's pickle module.

To un-pickle the data you can:

import pickle


with open('serialized.pkl', 'rb') as f:
    data = pickle.load(f)

For the MNIST data set

Note gzip is only needed if the file is compressed:

import gzip
import pickle


with gzip.open('mnist.pkl.gz', 'rb') as f:
    train_set, valid_set, test_set = pickle.load(f)

Where each set can be further divided (i.e. for the training set):

train_x, train_y = train_set

Those would be the inputs (digits) and outputs (labels) of your sets.

If you want to display the digits:

import matplotlib.cm as cm
import matplotlib.pyplot as plt


plt.imshow(train_x[0].reshape((28, 28)), cmap=cm.Greys_r)
plt.show()

The other alternative would be to look at the original data:

http://yann.lecun.com/exdb/mnist/

But that will be harder, as you'll need to create a program to read the binary data in those files. So I recommend you to use Python, and load the data with pickle. As you've seen, it's very easy. ;-)

In phpMyAdmin 4.0, you go to Status > Monitor. In there you can enable the slow query log and general log, see a live monitor, select a portion of the graph, see the related queries and analyse them.

I like thinking about design pattens in terms of my classes being 'people,' and the patterns are the ways that the people talk to each other.

So, to me the factory pattern is like a hiring agency. You've got someone that will need a variable number of workers. This person may know some info they need in the people they hire, but that's it.

So, when they need a new employee, they call the hiring agency and tell them what they need. Now, to actually hire someone, you need to know a lot of stuff - benefits, eligibility verification, etc. But the person hiring doesn't need to know any of this - the hiring agency handles all of that.

In the same way, using a Factory allows the consumer to create new objects without having to know the details of how they're created, or what their dependencies are - they only have to give the information they actually want.

public interface IThingFactory
{
    Thing GetThing(string theString);
}

public class ThingFactory : IThingFactory
{
    public Thing GetThing(string theString)
    {
        return new Thing(theString, firstDependency, secondDependency);
    }
}

So, now the consumer of the ThingFactory can get a Thing, without having to know about the dependencies of the Thing, except for the string data that comes from the consumer.

public class Test{

Test2 test = new Test2();
JFrame frame = new JFrame();

Test(){
...
frame.setLayout(new BorderLayout());
frame.add(test, BorderLayout.CENTER);
...
}

//main
...
}

//public class Test2{
public class Test2 extends JPanel {

//JPanel test2 = new JPanel();

Test2(){
...
}

Use the following function can change the margin/padding of the text in UITextView

public func UIEdgeInsetsMake(_ top: CGFloat, _ left: CGFloat, _ bottom: CGFloat, _ right: CGFloat) -> UIEdgeInsets

so in this case is

 self.textView?.textContainerInset = UIEdgeInsetsMake(0, 0, 0, 0)

Download the bootbox typings

Then add a reference to it inside your .ts file.

from pyspark.sql.functions import col

df.select(col("column_name")).collect()

here collect is functions which in turn convert it to list. Be ware of using the list on the huge data set. It will decrease performance. It is good to check the data.

Even though this question is quite old and has many different answers, I'd still like to add the imho most "pythonic" and also readable/concise answer.

Since the general tuple printing method is already shown correctly by Antimony, this is an addition for printing each element in a tuple separately, as Fong Kah Chun has shown correctly with the %s syntax.

Interestingly it has been only mentioned in a comment, but using an asterisk operator to unpack the tuple yields full flexibility and readability using the str.format method when printing tuple elements separately.

tup = (1, 2, 3)
print('Element(s) of the tuple: One {0}, two {1}, three {2}'.format(*tup))

This also avoids printing a trailing comma when printing a single-element tuple, as circumvented by Jacob CUI with replace. (Even though imho the trailing comma representation is correct if wanting to preserve the type representation when printing):

tup = (1, )
print('Element(s) of the tuple: One {0}'.format(*tup))

In my case, I don't need to set up anything further after installing Anaconda on Ubuntu

here is my screenshot for the version info.

I dug into this and all the answers above are partially right. It all depends on how the container is launched. It comes down to the following when the container was launched:

• was a TTY allocated (-t)
• was stdin left open (-i)

^P^Q does work, BUT only when -t and -i is used to launch the container:

[berto@g6]$ docker run -ti -d --name test python:3.6 /bin/bash -c 'while [ 1 ]; do sleep 30; done;'
b26e39632351192a9a1a00ea0c2f3e10729b6d3e22f8e0676d6519e15c08b518

[berto@g6]$ docker attach test
# here I typed ^P^Q
read escape sequence

# i'm back to my prompt
[berto@g6]$ docker kill test; docker rm -v test
test
test

ctrl+c does work, BUT only when -t (without -i) is used to launch the container:

[berto@g6]$ docker run -t -d --name test python:3.6 /bin/bash -c 'while [ 1 ]; do sleep 30; done;'
018a228c96d6bf2e73cccaefcf656b02753905b9a859f32e60bdf343bcbe834d

[berto@g6]$ docker attach test
^C

[berto@g6]$    

The third way to detach

There is a way to detach without killing the container though; you need another shell. In summary, running this in another shell detached and left the container running pkill -9 -f 'docker.*attach':

[berto@g6]$ docker run -d --name test python:3.6 /bin/bash -c 'while [ 1 ]; do sleep 30; done;'
b26e39632351192a9a1a00ea0c2f3e10729b6d3e22f8e0676d6519e15c08b518

[berto@g6]$ docker attach test
# here I typed ^P^Q and doesn't work
^P
# ctrl+c doesn't work either
^C
# can't background either
^Z

# go to another shell and run the `pkill` command above

# i'm back to my prompt
[berto@g6]$

Why? Because you're killing the process that connected you to the container, not the container itself.

If you want to use 'lengthMenu' together with buttons(copy, export), you have to use this option dom: 'lBfrtip'. Here https://datatables.net/reference/option/dom you can find meaning of each symbol. For example, if you will use like this 'Bfrtip', lengthMenu will not appears.

ngModel usually use for input tags for bind a variable that we can change variable from controller and html page but ngBind use for display a variable in html page and we can change variable just from controller and html just show variable.

In a nutshell - you can have two String objects that contain the same characters but are different objects (in different memory locations). The == operator checks to see that two references are pointing to the same object (memory location), but the equals() method checks if the characters are the same.

Usually you are interested in checking if two Strings contain the same characters, not whether they point to the same memory location.

i think u can set the heiht at runtime for 1 item just scrollView.setHeight(200px), for 2 items scrollView.setheight(400px) for 3 or more scrollView.setHeight(600px)

You can simply do tar -xvf <rpm file> as well!

Make the script executable by the user "Kev" and then remove the try it running through the command sh kev@server1 /test/foo.sh

I prefer the JOIN to join full tables/Views and then use the WHERE To introduce the predicate of the resulting set.

It feels syntactically cleaner.

Try numpy.array_split.

From the documentation:

>>> x = np.arange(8.0)
>>> np.array_split(x, 3)
    [array([ 0.,  1.,  2.]), array([ 3.,  4.,  5.]), array([ 6.,  7.])]

Identical to numpy.split, but won't raise an exception if the groups aren't equal length.

If number of chunks > len(array) you get blank arrays nested inside, to address that - if your split array is saved in a, then you can remove empty arrays by:

[x for x in a if x.size > 0]

Just save that back in a if you wish.

Simply single line of code:

self.tblViewMessages.scrollToRow(at: IndexPath.init(row: arrayChat.count-1, section: 0), at: .bottom, animated: isAnimeted)

You are right. ArrayList.contains() tests equals(), not object identity:

returns true if and only if this list contains at least one element e such that (o==null ? e==null : o.equals(e))

If you got a NullPointerException, verify that you initialized your list, either in a constructor or the declaration. For example:

private List<String> rssFeedURLs = new ArrayList<String>();

s = set([1,2,3])
print [ x for x in iter(s) ]

In the request object you have everything you need. To understand it:

debug($this->request->url);

and in your case

$here = $this->request->url;

i found another way without much effort.

Just simply right click your solution and then click undo pending changes.

Next, VS will ask you for acutally changed file where you want to undo or not specific file.

In this you can click no for such a file where actual change is happende, rest is just undoing. This will not lost your actual changes

Yes, the garbage collector will remove them as well. Might not always be the case with legacy browsers though.

Read the part with the title 'What is the best way to store the files in the Database?'

Software application written with Arduino, an IDE used for prototyping electronics; contains source code written in the Arduino programming language; enables developers to control the electronics on an Arduino circuit board.

To avoid file association conflicts with the Processing software, Arduino changed the Sketch file extension to .INO with the version 1.0 release. Therefore, while Arduino can still open ".pde" files, the ".ino" file extension should be used instead.

Each PDE file is stored in its own folder when saved from the Processing IDE. It is saved with any other program assets, such as images. The project folder and PDE filename prefix have the same name. When the PDE file is run, it is opened in a Java display window, which renders and runs the resulting program.

Processing is commonly used in educational settings for teaching basic programming skills in a visual environment.

Here's my docker-compose based solution:

  cron:
    image: alpine:3.10
    command: crond -f -d 8
    depends_on:
      - servicename
    volumes:
      - './conf/cron:/etc/crontabs/root:z'
    restart: unless-stopped

the lines with cron entries are on the ./conf/cron file.

Note: this won't run commands that aren't on the alpine image.

For UBUNTU you can try the following command to check mysql version :

mysql --version

$total=0;
foreach($group as $key=>$value)
{
   echo $key. " = " .$value. "<br>"; 
   $total+= $value;
}
echo $total;

My code to solve this problem:

private void sendMail()
{   
    //This list can be a parameter of metothd
    List<MailAddress> lst = new List<MailAddress>();

    lst.Add(new MailAddress("[email protected]"));
    lst.Add(new MailAddress("[email protected]"));
    lst.Add(new MailAddress("[email protected]"));
    lst.Add(new MailAddress("[email protected]"));


    try
    {


        MailMessage objeto_mail = new MailMessage();
        SmtpClient client = new SmtpClient();
        client.Port = 25;
        client.Host = "10.15.130.28"; //or SMTP name
        client.Timeout = 10000;
        client.DeliveryMethod = SmtpDeliveryMethod.Network;
        client.UseDefaultCredentials = false;
        client.Credentials = new System.Net.NetworkCredential("[email protected]", "password");
        objeto_mail.From = new MailAddress("[email protected]");

        //add each email adress
        foreach (MailAddress m in lst)
        {
            objeto_mail.To.Add(m);
        }


        objeto_mail.Subject = "Sending mail test";
        objeto_mail.Body = "Functional test for automatic mail :-)";
        client.Send(objeto_mail);


    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message);

array_combine() worked great for me while combining $_POST multiple values from multiple form inputs in an attempt to update products quantities in a shopping cart.

String int2string = Integer.toHexString(INTEGERColor); //to ARGB
String HtmlColor = "#"+ int2string.substring(int2string.length() - 6, int2string.length()); // a stupid way to append your color

java.io.DataInput.readUTF() and java.io.DataOutput.writeUTF(String) say that a String object is represented by two bytes of length information and the modified UTF-8 representation of every character in the string. This concludes that the length of String is limited by the number of bytes of the modified UTF-8 representation of the string when used with DataInput and DataOutput.

In addition, The specification of CONSTANT_Utf8_info found in the Java virtual machine specification defines the structure as follows.

CONSTANT_Utf8_info {
    u1 tag;
    u2 length;
    u1 bytes[length];
}

You can find that the size of 'length' is two bytes.

That the return type of a certain method (e.g. String.length()) is int does not always mean that its allowed maximum value is Integer.MAX_VALUE. Instead, in most cases, int is chosen just for performance reasons. The Java language specification says that integers whose size is smaller than that of int are converted to int before calculation (if my memory serves me correctly) and it is one reason to choose int when there is no special reason.

The maximum length at compilation time is at most 65536. Note again that the length is the number of bytes of the modified UTF-8 representation, not the number of characters in a String object.

String objects may be able to have much more characters at runtime. However, if you want to use String objects with DataInput and DataOutput interfaces, it is better to avoid using too long String objects. I found this limitation when I implemented Objective-C equivalents of DataInput.readUTF() and DataOutput.writeUTF(String).

There are 2 possible problems are:

• Firstly, you have not used the using System which should be before writing code that uses "System class", as Console.WriteLine()
• Secondly, you have not coded what happens after the Console displays "Test"

The possible solution will be:

using System;

namespace Test
{
    public static Main()
    {
        //Print to the console
        Console.WriteLine("Test");

        //Allow user to read output
        Console.ReadKey();
    }
}

It is also strategic to code Console.Write("Press any key to exit..."); on the line that precedes the Console.ReadKey(); to make the user aware that the program is ending, he/she must press any key to exit.

If the version of the app that you have installed was not built with the same keystore/signing certificate it will have a different signature. By default each build machine will have a different debug certificate unless you specify how it should be signed according to the google documentation, which can be used to ensure that your app will be build with the same debug key regardless of which computer you build the application on.

In order to proceed with the installation you must uninstall the existing version and then try again.

I was searching for this answer for a while. Now I got it in the official gulp documentation.

If you want to perform a gulp task when the last one is complete, you have to return a stream:

gulp.task('wiredep', ['dev-jade'], function () {_x000D_
    var stream = gulp.src(paths.output + '*.html')_x000D_
        .pipe($.wiredep())_x000D_
        .pipe(gulp.dest(paths.output));_x000D_
_x000D_
    return stream; // execute next task when this is completed_x000D_
});_x000D_
_x000D_
// First will execute and complete wiredep task_x000D_
gulp.task('prod-jade', ['wiredep'], function() {_x000D_
    gulp.src(paths.output + '**/*.html')_x000D_
        .pipe($.minifyHtml())_x000D_
        .pipe(gulp.dest(paths.output));_x000D_
});

To check for an empty string you could also do something as follows

if (!defined $val || $val eq '')
{
    # empty
}

Here's a simple one written in VB for an ASPX page:

                If myVar > 1 Then
                    response.write("Greater than 1")
                else
                    response.write("Not!")
                End If

You can use multiselect function for this.

   CriteriaBuilder cb=session.getCriteriaBuilder();
            CriteriaQuery<Object[]> cquery=cb.createQuery(Object[].class);
            Root<Car> root=cquery.from(User.class);
            cquery.multiselect(root.get("id"),root.get("Name"));
            Query<Object[]> q=session.createQuery(cquery);
            List<Object[]> list=q.getResultList();
            System.out.println("id        Name");
            for (Object[] objects : list) {
                System.out.println(objects[0]+"        "+objects[1]);
             }
            

This is supported by hibernate 5. createCriteria is deprecated in further version of hibernate. So you can use criteria builder instead.

No need to get too complicated. If all you need is ² then use the unicode representation.

http://en.wikipedia.org/wiki/Unicode_subscripts_and_superscripts

(which is how I assume you got the ² to appear in your question. )

Quick and easy, add this to your page:

<style>
    .select2-results {
        max-height: 500px;
    }
</style>

function Update(key, value)
{    
    for (var i = 0; i < array.length; i++) {
        if (array[i].Key == key) {
            array[i].Value = value; 
            break;
        }
    }
}

Just in case anyone else ends up here from a web search, and has Grunt already in their dependency list, the answer to this becomes trivial. Here's my solution:

/**
 * Return all the subfolders of this path
 * @param {String} parentFolderPath - valid folder path
 * @param {String} glob ['/*'] - optional glob so you can do recursive if you want
 * @returns {String[]} subfolder paths
 */
getSubfolders = (parentFolderPath, glob = '/*') => {
    return grunt.file.expand({filter: 'isDirectory'}, parentFolderPath + glob);
}

@webdeb's answer didn't work for me, I hit an unexpected token error when compiling ES6 with Babel, doing named default exports.

This worked for me, however:

// Foo.js
export default Foo
...

// bundle.js
export { default as Foo } from './Foo'
export { default as Bar } from './Bar'
...

// and import somewhere..
import { Foo, Bar } from './bundle'

You can install TortoiseGit for Windows and include integration in context menu. I consider it the best tool to work with Git on Windows.

Long time ago, all browser providers were making JavaScript engines for their browsers and only they and god knew what was happening inside this. One beautiful day, ECMA international came and said: let's make engines based on common standard, let's make something general to make life more easy and fun, and they made that standard. Since all browser providers make their JavaScript engines based on ECMAScript core (standard).

For example, Google Chrome uses V8 engine and this is open source. You can download it and see how C++ program translates a command 'print' of JavaScript to machine code.

Internet Explorer uses JScript (Chakra) engine for their browser and others do so and they all uses common core.

By loading the .js file first and then calling the function via onclick, there's less coding and it's fairly obvious what's going on. We'll call the JS file zipcodehelp.js.

HTML:

<!DOCTYPE html>
<html>
<head>
    <title>Button to call JS function.</title>
</head>
<body>
    <h1>Use Button to execute function in '.js' file.</h1>
    <script type="text/javascript" src="zipcodehelp.js"></script>
    <button onclick="ZipcodeHelp();">Get Zip Help!</button>
</body>
</html>

And the contents of zipcodehelp.js is :

function ZipcodeHelp() {
  alert("If Zipcode is missing in list at left, do: \n\n\
    1. Enter any zipcode and click Create Client. \n\
    2. Goto Zipcodes and create new zip code. \n\
    3. Edit this new client from the client list.\n\
    4. Select the new zipcode." );
}

Hope that helps! Cheers!

I translated the code sample in this blog post into Python: How to detect when the client closes the connection?, and it works well for me:

from ctypes import (
    CDLL, c_int, POINTER, Structure, c_void_p, c_size_t,
    c_short, c_ssize_t, c_char, ARRAY
)


__all__ = 'is_remote_alive',


class pollfd(Structure):
    _fields_ = (
        ('fd', c_int),
        ('events', c_short),
        ('revents', c_short),
    )


MSG_DONTWAIT = 0x40
MSG_PEEK = 0x02

EPOLLIN = 0x001
EPOLLPRI = 0x002
EPOLLRDNORM = 0x040

libc = CDLL(None)

recv = libc.recv
recv.restype = c_ssize_t
recv.argtypes = c_int, c_void_p, c_size_t, c_int

poll = libc.poll
poll.restype = c_int
poll.argtypes = POINTER(pollfd), c_int, c_int


class IsRemoteAlive:  # not needed, only for debugging
    def __init__(self, alive, msg):
        self.alive = alive
        self.msg = msg

    def __str__(self):
        return self.msg

    def __repr__(self):
        return 'IsRemoteClosed(%r,%r)' % (self.alive, self.msg)

    def __bool__(self):
        return self.alive


def is_remote_alive(fd):
    fileno = getattr(fd, 'fileno', None)
    if fileno is not None:
        if hasattr(fileno, '__call__'):
            fd = fileno()
        else:
            fd = fileno

    p = pollfd(fd=fd, events=EPOLLIN|EPOLLPRI|EPOLLRDNORM, revents=0)
    result = poll(p, 1, 0)
    if not result:
        return IsRemoteAlive(True, 'empty')

    buf = ARRAY(c_char, 1)()
    result = recv(fd, buf, len(buf), MSG_DONTWAIT|MSG_PEEK)
    if result > 0:
        return IsRemoteAlive(True, 'readable')
    elif result == 0:
        return IsRemoteAlive(False, 'closed')
    else:
        return IsRemoteAlive(False, 'errored')

You can also run conditional statements on the Postion() which can be really helpful in many scenarios.

for eg.

 <xsl:if test="(position( )) = 1">
     //Show header only once
    </xsl:if>

You should also make sure that the ports WAMP uses aren't already in use.

That can be done by typing the following command into the command prompt:

netstat –o

Here is a code snippet, that counts number of files in a particular HDFS directory (I used this to determine how many reducers to use in a particular ETL code). You can easily modify this to suite your needs.

private int calculateNumberOfReducers(String input) throws IOException {
    int numberOfReducers = 0;
    Path inputPath = new Path(input);
    FileSystem fs = inputPath.getFileSystem(getConf());
    FileStatus[] statuses = fs.globStatus(inputPath);
    for(FileStatus status: statuses) {
        if(status.isDirectory()) {
            numberOfReducers += getNumberOfInputFiles(status, fs);
        } else if(status.isFile()) {
            numberOfReducers ++;
        }
    }
    return numberOfReducers;
}

/**
 * Recursively determines number of input files in an HDFS directory
 *
 * @param status instance of FileStatus
 * @param fs instance of FileSystem
 * @return number of input files within particular HDFS directory
 * @throws IOException
 */
private int getNumberOfInputFiles(FileStatus status, FileSystem fs) throws IOException  {
    int inputFileCount = 0;
    if(status.isDirectory()) {
        FileStatus[] files = fs.listStatus(status.getPath());
        for(FileStatus file: files) {
            inputFileCount += getNumberOfInputFiles(file, fs);
        }
    } else {
        inputFileCount ++;
    }

    return inputFileCount;
}

try (FileOutputStream out = new FileOutputStream(filename)) {
    bmp.compress(Bitmap.CompressFormat.PNG, 100, out); // bmp is your Bitmap instance
    // PNG is a lossless format, the compression factor (100) is ignored
} catch (IOException e) {
    e.printStackTrace();
}

I'm faced with the same problem and came across this post. Is this what's meant by the IDictionary approach:

Dictionary<Type, int> typeDict = new Dictionary<Type, int>
{
    {typeof(int),0},
    {typeof(string),1},
    {typeof(MyClass),2}
};

void Foo(object o)
{
    switch (typeDict[o.GetType()])
    {
        case 0:
            Print("I'm a number.");
            break;
        case 1:
            Print("I'm a text.");
            break;
        case 2:
            Print("I'm classy.");
            break;
        default:
            break;
    }
}

If so, I can't say I'm a fan of reconciling the numbers in the dictionary with the case statements.

This would be ideal but the dictionary reference kills it:

void FantasyFoo(object o)
{
    switch (typeDict[o.GetType()])
    {
        case typeDict[typeof(int)]:
            Print("I'm a number.");
            break;
        case typeDict[typeof(string)]:
            Print("I'm a text.");
            break;
        case typeDict[typeof(MyClass)]:
            Print("I'm classy.");
            break;
        default:
            break;
    }
}

Is there another implementation I've overlooked?

Sorry for resurrection. You could use child_process module to execute external js files in node.js

var child_process = require('child_process');

//EXECUTE yourExternalJsFile.js
child_process.exec('node yourExternalJsFile.js', (error, stdout, stderr) => {
    console.log(`${stdout}`);
    console.log(`${stderr}`);
    if (error !== null) {
        console.log(`exec error: ${error}`);
    }
});

A string to char array is as simple as

String str = "someString"; 
char[] charArray = str.toCharArray();

Can you explain a little more on what you are trying to do?

* Update *

if I am understanding your new comment, you can use a byte array and example is provided.

byte[] bytes = ByteBuffer.allocate(4).putInt(1695609641).array();

for (byte b : bytes) {
   System.out.format("0x%x ", b);
}

With the following output

0x65 0x10 0xf3 0x29

Binary Search

You can use Collections.binarySearch to search an element in your list (assuming the list is sorted):

Collections.binarySearch(list, new YourObject("a1", "b",
                "c"), new Comparator<YourObject>() {

            @Override
            public int compare(YourObject o1, YourObject o2) {
                return o1.getName().compareTo(o2.getName());
            }
        });

which will return a negative number if the object is not present in the collection or else it will return the index of the object. With this you can search for objects with different searching strategies.

You can use a Scanner and its nextInt() method.
Scanner also has nextLong() for larger integers, if needed.

In config.inc.php in the top-level directory, set

$cfg['DefaultLang'] = 'en-utf-8'; // Language if no other language is recognized
// or
$cfg['Lang'] = 'en-utf-8'; // Force this language for all users

If Lang isn't set, you should be able to select the language in the initial welcome screen, and the language your browser prefers should be preselected there.

As it is the top answer for this error, I am adding the case for XML here.

There is also a possibility that the object returned hasn't correctly defined XML structure. That was the case for me.

public @ResponseBody DataObject getData(

Was throwing the same error despite correct headers. The errors stopped when I added @XmlRootElement to the header of the object:

@XmlRootElement
public class DataObject {
    @XmlElement(name = "field", nillable = true)
    protected String field;

cd /path/to/backupdir/
git clone /path/to/repo
cd /path/to/repo
git remote add backup /path/to/backupdir
git push --set-upstream backup master

this creates a backup and makes the setup, so that you can do a git push to update your backup, what is probably what you want to do. Just make sure, that /path/to/backupdir and /path/to/repo are at least different hard drives, otherwise it doesn't make that much sense to do that.

Both commands are correct :

mvn clean install -Pdev1
mvn clean install -P dev1

The problem is most likely not profile activation, but the profile not accomplishing what you expect it to.

It is normal that the command :

mvn help:active-profiles

does not display the profile, because is does not contain -Pdev1. You could add it to make the profile appear, but it would be pointless because you would be testing maven itself.

What you should do is check the profile behavior by doing the following :

1. set activeByDefault to true in the profile configuration,
2. run mvn help:active-profiles (to make sure it is effectively activated even without -Pdev1),
3. run mvn install.

It should give the same results as before, and therefore confirm that the problem is the profile not doing what you expect.

Adding this intent filter to one of the activities declared in app manifest fixed this for me.

<activity

       <action android:name="android.intent.action.VIEW" />

Yahoo is very easy to use and provides customized data. Use the following page to learn more.

finance.yahoo.com/d/quotes.csv?s=AAPL+GOOG+MSFT=pder=.csv

WARNING - there are a few tutorials out there on the web that show you how to do this, but the region where you put in the stock symbols causes an error if you use it as posted. You will get a "MISSING FORMAT VALUE". The tutorials I found omits the commentary around GOOG.

Example URL for GOOG: http://download.finance.yahoo.com/d/quotes.csv?s=%40%5EDJI,GOOG&f=nsl1op&e=.csv

You can't delete a foreign key if it still references another table. First delete the reference

delete from kontakty
where id_osoby = 1;

DELETE FROM osoby 
WHERE id_osoby = 1;

You can also just "not" add a url inside the <a> tag, i do this for menus that are <a> tag driven with drop downs as well. If there is not drop down then i add the url but if there are drop downs with a <ul> <li> list i just remove it.

import org.apache.commons.lang.math.NumberUtils;

This will handle null

NumberUtils.createLong(String)

Failed to open stream error occurs because the given path is wrong such as:

$uploadedFile->saveAs(Yii::app()->request->baseUrl.'/images/'.$model->user_photo);

It will give an error if the images folder will not allow you to store images, be sure your folder is readable

Using d.Keys()(i) method is a very bad idea, because on each call it will re-create a new array (you will have significant speed reduction).

Here is an analogue of Scripting.Dictionary called "Hash Table" class from @TheTrick, that support such enumerator: http://www.cyberforum.ru/blogs/354370/blog2905.html

Dim oDict As clsTrickHashTable

Sub aaa()
    Set oDict = New clsTrickHashTable

    oDict.Add "a", "aaa"
    oDict.Add "b", "bbb"

    For i = 0 To oDict.Count - 1
        Debug.Print oDict.Keys(i) & " - " & oDict.Items(i)
    Next
End Sub

Netbeans hints:

You get code completion on $users[0]-> and for $this-> for an array of User classes.

/**
 * @var User[]
 */
var $users = array();

You also can see the type of the array in a list of class members when you do completion of $this->...

This is the code I use:

var ifrm = document.getElementById('myFrame');
ifrm = (ifrm.contentWindow) ? ifrm.contentWindow : (ifrm.contentDocument.document) ? ifrm.contentDocument.document : ifrm.contentDocument;
ifrm.document.open();
ifrm.document.write('Hello World!');
ifrm.document.close();

contentWindow vs. contentDocument

• IE (Win) and Mozilla (1.7) will return the window object inside the iframe with oIFrame.contentWindow.
• Safari (1.2.4) doesn't understand that property, but does have oIframe.contentDocument, which points to the document object inside the iframe.
• To make it even more complicated, Opera 7 uses oIframe.contentDocument, but it points to the window object of the iframe. Because Safari has no way to directly access the window object of an iframe element via standard DOM (or does it?), our fully modern-cross-browser-compatible code will only be able to access the document within the iframe.

if you are using FragmentActivity. then do like this

first call This inside your Fragment.

public void callParentMethod(){
    getActivity().onBackPressed();
}

and then Call onBackPressed method in side your parent FragmentActivity class.

@Override
public void onBackPressed() {
  //super.onBackPressed();
  //create a dialog to ask yes no question whether or not the user wants to exit
  ...
}

This is using dataframes from the pandas package. The "index" part can be either a single index, a list of indices, or a list of booleans. This can be read about in the documentation: https://pandas.pydata.org/pandas-docs/stable/indexing.html

So the index part specifies a subset of the rows to pull out, and the (optional) column_name specifies the column you want to work with from that subset of the dataframe. So if you want to update the 'class' column but only in rows where the class is currently set as 'versicolor', you might do something like what you list in the question:

iris_data.loc[iris_data['class'] == 'versicolor', 'class'] = 'Iris-versicolor'

If you work with visual studio designer, you will probably have defined fields for each columns in the YourForm.Designer.cs file e.g.:

private System.Windows.Forms.DataGridViewCheckBoxColumn dataGridViewCheckBoxColumn1;    
private System.Windows.Forms.DataGridViewTextBoxColumn dataGridViewTextBoxColumn2; 

If you give them useful names, you can set the HeaderText easily:

usefulNameForDataGridViewTextBoxColumn.HeaderText = "Useful Header Text";

This is what i've implemented:

$(window).resize(function(){ setTimeout(someFunction, 500); });

we can clear the setTimeout if we expect resize to happen less than 500ms

Good Luck...

stringstream.str() returns a temporary string object that's destroyed at the end of the full expression. If you get a pointer to a C string from that (stringstream.str().c_str()), it will point to a string which is deleted where the statement ends. That's why your code prints garbage.

You could copy that temporary string object to some other string object and take the C string from that one:

const std::string tmp = stringstream.str();
const char* cstr = tmp.c_str();

Note that I made the temporary string const, because any changes to it might cause it to re-allocate and thus render cstr invalid. It is therefor safer to not to store the result of the call to str() at all and use cstr only until the end of the full expression:

use_c_str( stringstream.str().c_str() );

Of course, the latter might not be easy and copying might be too expensive. What you can do instead is to bind the temporary to a const reference. This will extend its lifetime to the lifetime of the reference:

{
  const std::string& tmp = stringstream.str();   
  const char* cstr = tmp.c_str();
}

IMO that's the best solution. Unfortunately it's not very well known.

It's rather simple. Private setters allow you to create read-only public or protected properties.

That's it. That's the only reason.

Yes, you can create a read-only property by only specifying the getter, but with auto-implmeneted properties you are required to specify both get and set, so if you want an auto-implemented property to be read-only, you must use private setters. There is no other way to do it.

It's true that Private setters were not created specificlly for auto-implemented read-only properties, but their use is a bit more esoteric for other reasons, largely centering around read-only properties and the use of reflection and serialization.

It doesn't matter will you set OnItemSelectedListener in onCreate or onStart - it will still be called during of Activity creation or start (respectively).
So we can set it in onCreate (and NOT in onStart!).
Just add a flag to figure out first initialisation:

private Spinner mSpinner;
private boolean mSpinnerInitialized;

then in onCreate (or onCreateView) just:

mSpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
            public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
                if (!mSpinnerInitialized) {
                    mSpinnerInitialized = true;
                    return;
                }

                // do stuff
            }

            public void onNothingSelected(AdapterView<?> adapterView) {
                return;
            }
        });

Try

 $(document).on('change','#multiid',function(){
    alert('Change Happened');
});

As your select-box is generated from the code, so you have to use event delegation, where in place of $(document) you can have closest parent element.

Or

$(document.body).on('change','#multiid',function(){
    alert('Change Happened');
});

Update:

Second one works fine, there is another change of selector to make it work.

$('#addbasket').on('change','#multiid',function(){
    alert('Change Happened');
});

Ideally we should use $("#addbasket") as it's the closest parent element [As i have mentioned above].

As an alternative to the other (very good) answers, you could cast to uintptr_t or intptr_t (from stdint.h/inttypes.h) and use the corresponding integer conversion specifiers. This would allow more flexibility in how the pointer is formatted, but strictly speaking an implementation is not required to provide these typedefs.

React Native comes with "Dimensions" api which we need to import from 'react-native'

import { Dimensions } from 'react-native';

Then,

<Image source={pic} style={{width: Dimensions.get('window').width, height: Dimensions.get('window').height}}></Image>

You may need to write a javascript for each button submit. Instead of defining action in form definition, set those values in javascript. Something like below.

function callButton1(form, yourServ)
{
form.action = yourServ;
form.submit();
});

Typically, you would use a hash table and function object, both available in Boost, TR1 and C++0x.

void func1() {
}
std::unordered_map<std::string, std::function<void()>> hash_map;
hash_map["Value1"] = &func1;
// .... etc
hash_map[mystring]();

This is a little more overhead at runtime but a bajillion times more maintainable. Hash tables offer O(1) insertion, lookup, and etc, which makes them the same complexity as the assembly-style jump-table.

U can use this Edittext....This will help you.

<EditText
android:id="@+id/EditText02"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:lines="5"
android:gravity="top|left"
android:inputType="textMultiLine" />

If your using Java8 you can use the IntStream:

int[] listOfNumbers = {5,4,13,7,7,8,9,10,5,92,11,3,4,2,1};
System.out.println(IntStream.of(listOfNumbers).sum());

Results: 181

Just 1 line of code which will sum the array.

Use following code:

UIBarButtonItem *customBtn=[[UIBarButtonItem alloc] initWithTitle:@"Custom" style:UIBarButtonItemStylePlain target:self action:@selector(customBtnPressed)];
[self.navigationItem setRightBarButtonItem:customBtn];

The query() function returns an object, you'll want fetch a record from what's returned from that function. Look at the examples on this page to learn how to print data from mysql

As suggested by theTuxRacer, you can use the eval command, for those who are missing it like I was, you can also add in your db name if you are not trying to preform operation on the default db.

mongo <dbname> --eval "printjson(db.something.find())"

In python2.x there was a dirty hack that served this purpose (NEVER use it unless absolutely necessary):

None < any integer < any string

Thus the check i < '' holds True for any integer i.

It has been reasonably deprecated in python3. Now such comparisons end up with

TypeError: unorderable types: str() < int()

Add the PORT envvariable to your serve script in package.json:

"serve": "PORT=4767 vue-cli-service serve",

By merging some of the techniques over here I came up with the simplest form:

#define MACROSTR(k) #k

#define X_NUMBERS \
       X(kZero  ) \
       X(kOne   ) \
       X(kTwo   ) \
       X(kThree ) \
       X(kFour  ) \
       X(kMax   )

enum {
#define X(Enum)       Enum,
    X_NUMBERS
#undef X
} kConst;

static char *kConstStr[] = {
#define X(String) MACROSTR(String),
    X_NUMBERS
#undef X
};

int main(void)
{
    int k;
    printf("Hello World!\n\n");

    for (k = 0; k < kMax; k++)
    {
        printf("%s\n", kConstStr[k]);
    }

    return 0;
}

Install the latest version of TDM-GCC here is the link-http://wiki.codeblocks.org/index.php/MinGW_installation

I tried all the stuff I found on the net (npm cache clear and rm -rf ~/.npm), but nothing seems to work. What solved the issue was updating node (and npm) to the latest version. Try that.

Try this:

Declare @DayOfMonth TinyInt Set @DayOfMonth = 13
Declare @Month TinyInt Set @Month = 6
Declare @Year Integer Set @Year = 2006
-- ------------------------------------
Select DateAdd(day, @DayOfMonth - 1, 
          DateAdd(month, @Month - 1, 
              DateAdd(Year, @Year-1900, 0)))

It works as well, has added benefit of not doing any string conversions, so it's pure arithmetic processing (very fast) and it's not dependent on any date format This capitalizes on the fact that SQL Server's internal representation for datetime and smalldatetime values is a two part value the first part of which is an integer representing the number of days since 1 Jan 1900, and the second part is a decimal fraction representing the fractional portion of one day (for the time) --- So the integer value 0 (zero) always translates directly into Midnight morning of 1 Jan 1900...

or, thanks to suggestion from @brinary,

Select DateAdd(yy, @Year-1900,  
       DateAdd(m,  @Month - 1, @DayOfMonth - 1)) 

Edited October 2014. As Noted by @cade Roux, SQL 2012 now has a built-in function:
DATEFROMPARTS(year, month, day)
that does the same thing.

Edited 3 Oct 2016, (Thanks to @bambams for noticing this, and @brinary for fixing it), The last solution, proposed by @brinary. does not appear to work for leap years unless years addition is performed first

select dateadd(month, @Month - 1, 
     dateadd(year, @Year-1900, @DayOfMonth - 1)); 

Take a look at ImageView.ScaleType to control and understand the way resizing happens in an ImageView. When the image is resized (while maintaining its aspect ratio), chances are that either the image's height or width becomes smaller than ImageView's dimensions.

You can examine the url through several Request fields:

Imagine your application is listening on the following application root:

http://www.example.com/myapplication

And a user requests the following URI:

http://www.example.com/myapplication/foo/page.html?x=y

In this case the values of the above mentioned attributes would be the following:

    path             /foo/page.html
    full_path        /foo/page.html?x=y
    script_root      /myapplication
    base_url         http://www.example.com/myapplication/foo/page.html
    url              http://www.example.com/myapplication/foo/page.html?x=y
    url_root         http://www.example.com/myapplication/

You can easily extract the host part with the appropriate splits.

Note that if you are getting this error instead:

fatal: could not read Username for 'https://github.com': No error

Then you need to update your Git to version 2.16 or later.

In visual studio 2015, goto->view->formatting marks, unselect show

You can simply use the zoom property:

#myContainer{
    zoom: 0.5;
    -moz-transform: scale(0.5);
}

Where myContainer contains all the elements you're editing. This is supported in all major browsers.

I hope you managed to obtain the json data from the json string.

Well I think this will be of help

try {
OkHttpClient client = new OkHttpClient();
Request request = new Request.Builder()
    .url(urls[0])
    .build();
Response responses = null;

try {
    responses = client.newCall(request).execute();
} catch (IOException e) {
    e.printStackTrace();
}   

String jsonData = responses.body().string();

JSONObject Jobject = new JSONObject(jsonData);
JSONArray Jarray = Jobject.getJSONArray("employees");

//define the strings that will temporary store the data
String fname,lname;

//get the length of the json array
int limit = Jarray.length()

//datastore array of size limit
String dataStore[] = new String[limit];

for (int i = 0; i < limit; i++) {
    JSONObject object     = Jarray.getJSONObject(i);

    fname = object.getString("firstName");
    lname = object.getString("lastName");

    Log.d("JSON DATA", fname + " ## " + lname);

    //store the data into the array
    dataStore[i] = fname + " ## " + lname;
}

//prove that the data was stored in the array      
 for (String content ; dataStore ) {
        Log.d("ARRAY CONTENT", content);
    }

Remember to use AsyncTask or SyncAdapter(IntentService), to prevent getting a NetworkOnMainThreadException

Also import the okhttp library in your build.gradle

compile 'com.squareup.okhttp:okhttp:2.4.0'

A way around this would be to use Object datatype instead:

Private _myDate As Object
Private Property MyDate As Date
    Get
        If IsNothing(_myDate) Then Return Nothing
        Return CDate(_myDate)
    End Get
    Set(value As Date)
        If date = Nothing Then
            _myDate = Nothing
            Return
        End If
        _myDate = value
     End Set
End Property

Then you can set the date to nothing like so:

MyDate = Nothing
Dim theDate As Date = MyDate
If theDate = Nothing Then
    'date is nothing
End If

If you want to use a anchor you can use http://api.jquery.com/event.preventDefault/ like the other answers suggested.

You can also use any other element like a span and attach the click event to that.

$("span.clickable").click(function(){
alert('Yeah I was clicked');
});

To apply it everywhere, you could do something like

$('body').on('click', function() {
   if($('.children').is(':visible')) {
      $('ul.children').slideUp('slow');
   }
});

first thing first, all shards failed exception is not as dramatic as it sounds, it means shards were failed while serving a request(query or index), and there could be multiple reasons for it like

1. Shards are actually in non-recoverable state, if your cluster and index state are in Yellow and RED, then it is one of the reason.
2. Due to some shard recovery happening in background, shards didn't respond.
3. Due to bad syntax of your query, ES responds in all shards failed.

In order to fix the issue, you need to filter it in one of the above category and based on that appropriate fix is required.

The one mentioned in the question, is clearly in the first bucket as cluster health is RED, means one or more primary shards are missing, and my this SO answer will help you fix RED cluster issue, which will fix the all shards exception in this case.

In the MySQL interactive client you can type:

source yourfile.sql

Alternatively you can pipe the data into mysql from the command line:

mysql < yourfile.sql

If the file doesn't specify a database then you will also need to add that:

mysql db_name < yourfile.sql

See the documentation for more details:

• Executing SQL Statements from a Text File

Another way to accomplish the same thing...

List<Car> distinticBy = cars
    .Select(car => car.CarCode)
    .Distinct()
    .Select(code => cars.First(car => car.CarCode == code))
    .ToList();

It's possible to create an extension method to do this in a more generic way. It would be interesting if someone could evalute performance of this 'DistinctBy' against the GroupBy approach.

This will give you the full version of Windows (including Revision/Build number) unlike all the solutions above:

(Get-ItemProperty -Path c:\windows\system32\hal.dll).VersionInfo.FileVersion

Result:

10.0.10240.16392 (th1_st1.150716-1608)

If you are using JDK 8, there is no reason to use abstract classes because whatever we do with abstract classes we can now do it with interfaces because of default methods. If you use abstract class you have to extend it and there is a restriction that you can extends only once. But if you use interface you can implements as many as you want.

Interface is by default an abstract class an all methods and constructors are public.

It might not exactly be the same error, but I had a similar one.

Check Maven Java Version

Since Maven is also runnig with Java, check first with which version your Maven is running on:

mvn --version | grep -i java 

It returns:

Java version 1.8.0_151, vendor: Oracle Corporation, runtime: C:\tools\jdk\openjdk1.8

Incompatible version

Here above my maven is running with Java Version 1.8.0_151. So even if I specify maven to compile with Java 11:

<properties>
    <java.version>11</java.version>
    <maven.compiler.source>${java.version}</maven.compiler.source>
    <maven.compiler.target>${java.version}</maven.compiler.target>
</properties>

It will logically print out this error:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.0:compile (default-compile) on project efa-example-commons-task: Fatal error compiling: invalid target release: 11 -> [Help 1]

How to set specific java version to Maven

The logical thing to do is to set a higher Java Version to Maven (e.g. Java version 11 instead 1.8).

Maven make use of the environment variable JAVA_HOME to find the Java Version to run. So change this variable to the JDK you want to compile against (e.g. OpenJDK 11).

Sanity check

Then run again mvn --version to make sure the configuration has been taken care of:

mvn --version | grep -i java

yields

Java version: 11.0.2, vendor: Oracle Corporation, runtime: C:\tools\jdk\openjdk11

Which is much better and correct to compile code written with the Java 11 specifications.

As a reference, this is how I extended the open method as per @john-macintyre's suggestion:

$.widget( "ui.dialog", $.ui.dialog, {_x000D_
 open: function() {_x000D_
  $(this.uiDialogTitlebarClose)_x000D_
   .html("<span class='ui-button-icon-primary ui-icon ui-icon-closethick'></span><span class='ui-button-text'>close</span>");_x000D_
  // Invoke the parent widget's open()._x000D_
  return this._super();_x000D_
 }_x000D_
});

best solution: from jQuery v1.6 you can use prop() to add a property

$('#someid').prop('disabled', true);

to remove it, use removeProp()

$('#someid').removeProp('disabled');

Reference

Also note that the .removeProp() method should not be used to set these properties to false. Once a native property is removed, it cannot be added again. See .removeProp() for more information.

All of the current answers use a literal string, which I prefer to not have in my code if possible - this does not (and provides valuable semantic meaning, to boot):

function isFunction(possibleFunction) {
  return typeof(possibleFunction) === typeof(Function);
}

Personally, I try to reduce the number of strings hanging around in my code...

Also, while I am aware that typeof is an operator and not a function, there is little harm in using syntax that makes it appear as the latter.

Ultimately you want to review the datetime documentation and become familiar with the formatting variables, but here are some examples to get you started:

import datetime

print('Timestamp: {:%Y-%m-%d %H:%M:%S}'.format(datetime.datetime.now()))
print('Timestamp: {:%Y-%b-%d %H:%M:%S}'.format(datetime.datetime.now()))
print('Date now: %s' % datetime.datetime.now())
print('Date today: %s' % datetime.date.today())

today = datetime.date.today()
print("Today's date is {:%b, %d %Y}".format(today))

schedule = '{:%b, %d %Y}'.format(today) + ' - 6 PM to 10 PM Pacific'
schedule2 = '{:%B, %d %Y}'.format(today) + ' - 1 PM to 6 PM Central'
print('Maintenance: %s' % schedule)
print('Maintenance: %s' % schedule2)

The output:

Timestamp: 2014-10-18 21:31:12

Timestamp: 2014-Oct-18 21:31:12

Date now: 2014-10-18 21:31:12.318340

Date today: 2014-10-18

Today's date is Oct, 18 2014

Maintenance: Oct, 18 2014 - 6 PM to 10 PM Pacific

Maintenance: October, 18 2014 - 1 PM to 6 PM Central

You can add a watchpoint for each variable you're interested in.

A watchpoint is a special breakpoint that stops the execution of an application whenever the value of a given expression changes, without specifying where it might occur. Unlike breakpoints (which are line-specific), watchpoints are associated with files. They take effect whenever a specified condition is true, regardless of when or where it occurred. You can set a watchpoint on a global variable by highlighting the variable in the editor, or by selecting it in the Outline view.

Yes, ensure like finally guarantees that the block will be executed. This is very useful for making sure that critical resources are protected e.g. closing a file handle on error, or releasing a mutex.

That's no struts related problem but rather plain HMTL/CSS.

I'm not HTML or CSS expert, but I guess you could use a div with a border on the left or right side only.

If you want to do this using regex, you could simply use a non-capturing group, to get the word "world" and then grab everything after, like so

(?:world).*

The example string is tested here

// Merge object2 into object1, recursively

$.extend( true, object1, object2 );

// Merge object2 into object1

$.extend( object1, object2 );

https://api.jquery.com/jquery.extend/

Yes, it is possible.

try:
   ...
except FirstException:
   handle_first_one()

except SecondException:
   handle_second_one()

except (ThirdException, FourthException, FifthException) as e:
   handle_either_of_3rd_4th_or_5th()

except Exception:
   handle_all_other_exceptions()

See: http://docs.python.org/tutorial/errors.html

The "as" keyword is used to assign the error to a variable so that the error can be investigated more thoroughly later on in the code. Also note that the parentheses for the triple exception case are needed in python 3. This page has more info: Catch multiple exceptions in one line (except block)

5== will indent five lines from the current cursor position.

So you can type any number before ==. It will indent the number of lines. This is in command mode.

gg=G will indent the whole file from top to bottom.

$fname = "database.php";
$fhandle = fopen($fname,"r");
$content = fread($fhandle,filesize($fname));
$content = str_replace("192.168.1.198", "localhost", $content);

$fhandle = fopen($fname,"w");
fwrite($fhandle,$content);
fclose($fhandle);

You can use stuff in place of replace for avoiding the bug that Hamlet Hakobyan has mentioned

CREATE FUNCTION dbo.StripWWWandCom (@input VARCHAR(250)) 
RETURNS VARCHAR(250) 
AS BEGIN
   DECLARE @Work VARCHAR(250)
   SET @Work = @Input

   --SET @Work = REPLACE(@Work, 'www.', '')
   SET @Work = Stuff(@Work,1,4, '')
   SET @Work = REPLACE(@Work, '.com', '')

   RETURN @work 
END

A simple way using std::next_permutation:

#include <iostream>
#include <algorithm>
#include <vector>

int main() {
    int n, r;
    std::cin >> n;
    std::cin >> r;

    std::vector<bool> v(n);
    std::fill(v.end() - r, v.end(), true);

    do {
        for (int i = 0; i < n; ++i) {
            if (v[i]) {
                std::cout << (i + 1) << " ";
            }
        }
        std::cout << "\n";
    } while (std::next_permutation(v.begin(), v.end()));
    return 0;
}

or a slight variation that outputs the results in an easier to follow order:

#include <iostream>
#include <algorithm>
#include <vector>

int main() {
   int n, r;
   std::cin >> n;
   std::cin >> r;

   std::vector<bool> v(n);
   std::fill(v.begin(), v.begin() + r, true);

   do {
       for (int i = 0; i < n; ++i) {
           if (v[i]) {
               std::cout << (i + 1) << " ";
           }
       }
       std::cout << "\n";
   } while (std::prev_permutation(v.begin(), v.end()));
   return 0;
}

A bit of explanation:

It works by creating a "selection array" (v), where we place r selectors, then we create all permutations of these selectors, and print the corresponding set member if it is selected in in the current permutation of v.

You can implement it if you note that for each level r you select a number from 1 to n.

In C++, we need to 'manually' keep the state between calls that produces results (a combination): so, we build a class that on construction initialize the state, and has a member that on each call returns the combination while there are solutions: for instance

#include <iostream>
#include <iterator>
#include <vector>
#include <cstdlib>

using namespace std;

struct combinations
{
    typedef vector<int> combination_t;

    // initialize status
   combinations(int N, int R) :
       completed(N < 1 || R > N),
       generated(0),
       N(N), R(R)
   {
       for (int c = 1; c <= R; ++c)
           curr.push_back(c);
   }

   // true while there are more solutions
   bool completed;

   // count how many generated
   int generated;

   // get current and compute next combination
   combination_t next()
   {
       combination_t ret = curr;

       // find what to increment
       completed = true;
       for (int i = R - 1; i >= 0; --i)
           if (curr[i] < N - R + i + 1)
           {
               int j = curr[i] + 1;
               while (i <= R-1)
                   curr[i++] = j++;
               completed = false;
               ++generated;
               break;
           }

       return ret;
   }

private:

   int N, R;
   combination_t curr;
};

int main(int argc, char **argv)
{
    int N = argc >= 2 ? atoi(argv[1]) : 5;
    int R = argc >= 3 ? atoi(argv[2]) : 2;
    combinations cs(N, R);
    while (!cs.completed)
    {
        combinations::combination_t c = cs.next();
        copy(c.begin(), c.end(), ostream_iterator<int>(cout, ","));
        cout << endl;
    }
    return cs.generated;
}

On upgrading to Xcode 8, I got a message to upgrade to recommended settings. I accepted and everything was updated. I started getting compile time issue :

Duplicate symbol for XXXX Duplicate symbol for XXXX Duplicate symbol for XXXX

A total of 143 errors. Went to Target->Build settings -> No Common Blocks -> Set it to NO. This resolved the issue. The issue was that the integrated projects had code blocks in common and hence was not able to compile it. Explanation can be found here.

If you're doing some performance tuning it's often recommended to set both -XX:PermSize and -XX:MaxPermSize to the same value to increase JVM efficiency.

Here is some information:

1. Support for large page heap on x86 and amd64 platforms
2. Java Support for Large Memory Pages
3. Setting the Permanent Generation Size

You can also specify -XX:+CMSClassUnloadingEnabled to enable class unloading option if you are using CMS GC. It may help to decrease the probability of Java.lang.OutOfMemoryError: PermGen space

I encountered the exact same problem today, Ryan.

In my src (or your root) directory, my log4j.properties file now has the following addition

Thanks for the heads up as to how to do this, Benjamin.

Right click the project and select properties Click the java compiler from the left and change to your required version Hope this helps

It might be the JavaScript check for some valid condition.
Two things you can perform a/c to your requirements:

1. either check for the valid string-input in the text-box.
2. or set a loop against that text box to enter the value until you post the form/request.

String barcode="0000000047166";

WebElement strLocator = driver.findElement(By.xpath("//*[@id='div-barcode']"));
strLocator.sendKeys(barcode);

For new Android Studio versions, go to C:\Program Files\Android\Android Studio\jre\bin(or to location of Android Studio installed files) and open command window at this location and type in following command in command prompt:-

java -version

On the one hand, throwing exceptions is inherently expensive, because the stack has to be unwound etc.
On the other hand, accessing a value in a dictionary by its key is cheap, because it's a fast, O(1) operation.

BTW: The correct way to do this is to use TryGetValue

obj item;
if(!dict.TryGetValue(name, out item))
    return null;
return item;

This accesses the dictionary only once instead of twice.
If you really want to just return null if the key doesn't exist, the above code can be simplified further:

obj item;
dict.TryGetValue(name, out item);
return item;

This works, because TryGetValue sets item to null if no key with name exists.

Just for kicks

mse = (np.linalg.norm(A-B)**2)/len(A)

Python 2 will automatically set the type based on the size of the value. A guide of max values can be found below.

The Max value of the default Int in Python 2 is 65535, anything above that will be a long

For example:

>> print type(65535)
<type 'int'>
>>> print type(65536*65536)
<type 'long'>

In Python 3 the long datatype has been removed and all integer values are handled by the Int class. The default size of Int will depend on your CPU architecture.

For example:

• 32 bit systems the default datatype for integers will be 'Int32'
• 64 bit systems the default datatype for integers will be 'Int64'

The min/max values of each type can be found below:

• Int8: [-128,127]
• Int16: [-32768,32767]
• Int32: [-2147483648,2147483647]
• Int64: [-9223372036854775808,9223372036854775807]
• Int128: [-170141183460469231731687303715884105728,170141183460469231731687303715884105727]
• UInt8: [0,255]
• UInt16: [0,65535]
• UInt32: [0,4294967295]
• UInt64: [0,18446744073709551615]
• UInt128: [0,340282366920938463463374607431768211455]

If the size of your Int exceeds the limits mentioned above, python will automatically change it's type and allocate more memory to handle this increase in min/max values. Where in Python 2, it would convert into 'long', it now just converts into the next size of Int.

Example: If you are using a 32 bit operating system, your max value of an Int will be 2147483647 by default. If a value of 2147483648 or more is assigned, the type will be changed to Int64.

There are different ways to check the size of the int and it's memory allocation. Note: In Python 3, using the built-in type() method will always return <class 'int'> no matter what size Int you are using.

To restate what I think the OP's question really is:

If I'm building an application principally in Angular 1.x, and (implicitly) doing so in the era of Grunt/Gulp/Broccoli and Bower/NPM, and I maybe have a couple additional library dependencies, does Require add clear, specific value beyond what I get by using Angular without Require?

Or, put another way:

"Does vanilla Angular need Require to manage basic Angular component-loading effectively, if I have other ways of handling basic script-loading?"

And I believe the basic answer to that is: "not unless you've got something else going on, and/or you're unable to use newer, more modern tools."

Let's be clear at the outset: RequireJS is a great tool that solved some very important problems, and started us down the road that we're on, toward more scalable, more professional Javascript applications. Importantly, it was the first time many people encountered the concept of modularization and of getting things out of global scope. So, if you're going to build a Javascript application that needs to scale, then Require and the AMD pattern are not bad tools for doing that.

But, is there anything particular about Angular that makes Require/AMD a particularly good fit? No. In fact, Angular provides you with its own modularization and encapsulation pattern, which in many ways renders redundant the basic modularization features of AMD. And, integrating Angular modules into the AMD pattern is not impossible, but it's a bit... finicky. You'll definitely be spending time getting the two patterns to integrate nicely.

For some perspective from the Angular team itself, there's this, from Brian Ford, author of the Angular Batarang and now a member of the Angular core team:

I don't recommend using RequireJS with AngularJS. Although it's certainly possible, I haven't seen any instance where RequireJS was beneficial in practice.

So, on the very specific question of AngularJS: Angular and Require/AMD are orthogonal, and in places overlapping. You can use them together, but there's no reason specifically related to the nature/patterns of Angular itself.

But what about basic management of internal and external dependencies for scalable Javascript applications? Doesn't Require do something really critical for me there?

I recommend checking out Bower and NPM, and particularly NPM. I'm not trying to start a holy war about the comparative benefits of these tools. I merely want to say: there are other ways to skin that cat, and those ways may be even better than AMD/Require. (They certainly have much more popular momentum in late-2015, particularly NPM, combined with ES6 or CommonJS modules. See related SO question.)

What about lazy-loading?

Note that lazy-loading and lazy-downloading are different. Angular's lazy-loading doesn't mean you're pulling them direct from the server. In a Yeoman-style application with javascript automation, you're concatenating and minifying the whole shebang together into a single file. They're present, but not executed/instantiated until needed. The speed and bandwidth improvements you get from doing this vastly, vastly outweigh any alleged improvements from lazy-downloading a particular 20-line controller. In fact, the wasted network latency and transmission overhead for that controller is going to be an order of magnitude greater than the size of the controller itself.

But let's say you really do need lazy-downloading, perhaps for infrequently-used pieces of your application, such as an admin interface. That's a very legitimate case. Require can indeed do that for you. But there are also many other, potentially more flexible options that accomplish the same thing. And Angular 2.0 will apparently take care of this for us, built-in to the router. (Details.)

But what about during development on my local dev boxen?

How can I get all my dozens/hundreds of script files loaded without needing to attach them all to index.html manually?

Have a look at the sub-generators in Yeoman's generator-angular, or at the automation patterns embodied in generator-gulp-angular, or at the standard Webpack automation for React. These provide you a clean, scalable way to either: automatically attach the files at the time that components are scaffolded, or to simply grab them all automatically if they are present in certain folders/match certain glob-patterns. You never again need to think about your own script-loading once you've got the latter options.

Bottom-line?

Require is a great tool, for certain things. But go with the grain whenever possible, and separate your concerns whenever possible. Let Angular worry about Angular's own modularization pattern, and consider using ES6 modules or CommonJS as a general modularization pattern. Let modern automation tools worry about script-loading and dependency-management. And take care of async lazy-loading in a granular way, rather than by tangling it up with the other two concerns.

That said, if you're developing Angular apps but can't install Node on your machine to use Javascript automation tools for some reason, then Require may be a good alternate solution. And I've seen really elaborate setups where people want to dynamically load Angular components that each declare their own dependencies or something. And while I'd probably try to solve that problem another way, I can see the merits of the idea, for that very particular situation.

But otherwise... when starting from scratch with a new Angular application and flexibility to create a modern automation environment... you've got a lot of other, more flexible, more modern options.

while(!feof(fp))
{
  ch = fgetc(fp);
  if(ch == '\n')
  {
    lines++;
  }
}

But please note: Why is “while ( !feof (file) )” always wrong?.

You need to use conditional jmp commands. This isn't the same syntax as you're using; looks like MASM, but using GAS here's an example from some code I wrote to calculate gcd:

gcd_alg:
    subl    %ecx, %eax      /* a = a - c */
    cmpl    $0, %eax        /* if a == 0 */
    je      gcd_done        /* jump to end */
    cmpl    %ecx, %eax      /* if a < c */
    jl      gcd_preswap     /* swap and start over */
    jmp     gcd_alg         /* keep subtracting */

Basically, I compare two registers with the cmpl instruction (compare long). If it is less the JL (jump less) instruction jumps to the preswap location, otherwise it jumps back to the same label.

As for clearing the screen, that depends on the system you're using.

In order to download a file to Download or Music Folder In SDCard

File downlodDir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS);// or DIRECTORY_PICTURES

And dont forget to add these permission in manifest

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

in my webpack.config.js (Version 1,2,3) file, I have

function isExternal(module) {
  var context = module.context;

  if (typeof context !== 'string') {
    return false;
  }

  return context.indexOf('node_modules') !== -1;
}

in my plugins array

plugins: [
  new CommonsChunkPlugin({
    name: 'vendors',
    minChunks: function(module) {
      return isExternal(module);
    }
  }),
  // Other plugins
]

Now I have a file that only adds 3rd party libs to one file as required.

If you want get more granular where you separate your vendors and entry point files:

plugins: [
  new CommonsChunkPlugin({
    name: 'common',
    minChunks: function(module, count) {
      return !isExternal(module) && count >= 2; // adjustable
    }
  }),
  new CommonsChunkPlugin({
    name: 'vendors',
    chunks: ['common'],
    // or if you have an key value object for your entries
    // chunks: Object.keys(entry).concat('common')
    minChunks: function(module) {
      return isExternal(module);
    }
  })
]

Note that the order of the plugins matters a lot.

Also, this is going to change in version 4. When that's official, I update this answer.

I had the same problem, I fixed it by removing PATHEXT from user variable. It must only exist in System variable with .COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.MSC

Also remove the variable from user to system and only include that path on user variable

Let us see the difference between the two HTTP authentication using Wireshark (Tool to analyse packets sent or received) .

1. Http Basic Authentication

As soon as the client types in the correct username:password,as requested by the Web-server, the Web-Server checks in the Database if the credentials are correct and gives the access to the resource .

Here is how the packets are sent and received :

In the first packet the Client fill the credentials using the POST method at the resource - lab/webapp/basicauth .In return the server replies back with http response code 200 ok ,i.e, the username:password were correct .

Now , In the Authorization header it shows that it is Basic Authorization followed by some random string .This String is the encoded (Base64) version of the credentials admin:aadd (including colon ) .

2 . Http Digest Authentication(rfc 2069)

So far we have seen that the Basic Authentication sends username:password in plaintext over the network .But the Digest Auth sends a HASH of the Password using Hash algorithm.

Here are packets showing the requests made by the client and response from the server .

As soon as the client types the credentials requested by the server , the Password is converted to a response using an algorithm and then is sent to the server , If the server Database has same response as given by the client the server gives the access to the resource , otherwise a 401 error .

In the above Authorization , the response string is calculated using the values of Username,Realm,Password,http-method,URI and Nonce as shown in the image :

(colons are included)

Hence , we can see that the Digest Authentication is more Secure as it involve Hashing (MD5 encryption) , So the packet sniffer tools cannot sniff the Password although in Basic Auth the exact Password was shown on Wireshark.

I'm afraid it's the best solution that I can think of. But you can use reserve() to pre-allocate the minimum required memory in advance to speed up things a bit. You'll end up with a new string that will probably be shorter but that takes up the same amount of memory, but you'll avoid reallocations.

EDIT: Depending on your situation, this may incur less overhead than jumbling characters around.

You should try different approaches and see what is best for you: you might not have any performance issues at all.

Please Try, if use "extends AppCompatActivity" and present actionbar.

 ActionBar eksinbar=getSupportActionBar();
if (eksinbar != null) {
    eksinbar.setDisplayHomeAsUpEnabled(true);
    eksinbar.setHomeAsUpIndicator(R.mipmap.imagexxx);
}

It's a general comparison operator. It returns either a -1, 0, or +1 depending on whether its receiver is less than, equal to, or greater than its argument.

There are no auto incrementing features in Oracle for a column. You need to create a SEQUENCE object. You can use the sequence like:

insert into table(batch_id, ...) values(my_sequence.nextval, ...)

...to return the next number. To find out the last created sequence nr (in your session), you would use:

my_sequence.currval

This site has several complete examples on how to use sequences.

Also, RESTful lets you get data back from a POST request.

xhr.setRequestHeader('Content-Type', 'application/json');

File-> Settings->Under IDE Settings click on Plugins. Now in right side window Click on Browse repositories and there you can find the plugins. Select which one you want and click on install

Use newDirName = os.path.abspath(dir) to create a full directory path name for the subdirectory and then list its contents as you have done with the parent (i.e. newDirList = os.listDir(newDirName))

You can create a separate method of your code snippet and call it recursively through the subdirectory structure. The first parameter is the directory pathname. This will change for each subdirectory.

This answer is based on the 3.1.1 version documentation of the Python Library. There is a good model example of this in action on page 228 of the Python 3.1.1 Library Reference (Chapter 10 - File and Directory Access). Good Luck!

InputStream in = getResources().openRawResource(resourceName);

This will work correctly. Before that you have to create the xml file / text file in raw resource. Then it will be accessible.

Edit
Some times com.andriod.R will be imported if there is any error in layout file or image names. So You have to import package correctly, then only the raw file will be accessible.

Just download and install openSSH for windows. It is open source, and it makes your cmd ssh ready. A quick google search will give you a tutorial on how to install it, should you need it.

After it is installed you can just go ahead and generate your public key if you want to put in on a server. You generate it by running:

ssh-keygen -t rsa

After that you can just can just press enter, it will automatically assign a name for the key (example: id_rsa.pub)

if you install npm correctly in this way:

npm install -g @angular/cli@latest

and still have that problem, it maybe because you run the command in shell and not in cmd (you need to run command in cmd), check this out and maybe it helps...

There is not really a straightforward way of getting the HTML source code of a webelement. You will have to use JavaScript. I am not too sure about python bindings, but you can easily do like this in Java. I am sure there must be something similar to JavascriptExecutor class in Python.

 WebElement element = driver.findElement(By.id("foo"));
 String contents = (String)((JavascriptExecutor)driver).executeScript("return arguments[0].innerHTML;", element);

I managed to do it by using the following code.

@Html.TextBoxFor(model => model.EndTime, new { type = "time" })

Instead of explicitly writing the class name you could use

this.getClass().getResource("/unibo/lsb/res/dice.jpg");

CharField has max_length of 255 characters while TextField can hold more than 255 characters. Use TextField when you have a large string as input. It is good to know that when the max_length parameter is passed into a TextField it passes the length validation to the TextArea widget.

Using newer C# features, namely out var, you can get rid of the static factory-method. I just found out (by accident) that out var parameter of methods called inse base-"call" flow to the constructor body.

Example, using this base class you want to derive from:

public abstract class BaseClass
{
    protected BaseClass(int a, int b, int c)
    {
    }
}

The non-compiling pseudo code you want to execute:

public class DerivedClass : BaseClass
{
    private readonly object fatData;

    public DerivedClass(int m)
    {
        var fd = new { A = 1 * m, B = 2 * m, C = 3 * m };
        base(fd.A, fd.B, fd.C); // base-constructor call
        this.fatData = fd;
    }
}

And the solution by using a static private helper method which produces all required base arguments (plus additional data if needed) and without using a static factory method, just plain constructor to the outside:

public class DerivedClass : BaseClass
{
    private readonly object fatData;

    public DerivedClass(int m)
        : base(PrepareBaseParameters(m, out var b, out var c, out var fatData), b, c)
    {
        this.fatData = fatData;
        Console.WriteLine(new { b, c, fatData }.ToString());
    }

    private static int PrepareBaseParameters(int m, out int b, out int c, out object fatData)
    {
        var fd = new { A = 1 * m, B = 2 * m, C = 3 * m };
        (b, c, fatData) = (fd.B, fd.C, fd); // Tuples not required but nice to use
        return fd.A;
    }
}

int RoundedUp = (int) Math.ceil(RandomReal);

This seemed to do the perfect job. Worked everytime.

This doesn't work. only one value is ever pre-selected even though both options are available in the list only the first is shown ('#searchproject').select2('val', ['New Co-location','Expansion']);

Rendering didn't work for me too. I had <null> value on the right side of the android icon. I ran

sudo apt-get install gradle

I restarted Android studio then and <null> value changed to 23.

Voila, it renders now! :)

To map predicted classes and filenames using ImageDataGenerator, I use:

# Data generator and prediction
test_datagen = ImageDataGenerator(rescale=1./255)
test_generator = test_datagen.flow_from_directory(
        inputpath,
        target_size=(150, 150),
        batch_size=20,
        class_mode='categorical',
        shuffle=False)
pred = model.predict_generator(test_generator, steps=len(test_generator), verbose=0)
# Get classes by max element in np (as a list)
classes = list(np.argmax(pred, axis=1))
# Get filenames (set shuffle=false in generator is important)
filenames = test_generator.filenames

I can loop over predicted classes and the associated filename using:

for f in zip(classes, filenames):
    ...

Warning: using attr() or prop() to change the state of a checkbox does not fire the change event in most browsers I've tested with. The checked state will change but no event bubbling. You must trigger the change event manually after setting the checked attribute. I had some other event handlers monitoring the state of checkboxes and they would work fine with direct user clicks. However, setting the checked state programmatically fails to consistently trigger the change event.

jQuery 1.6

$('.offer').bind('click', function(){ 
    var $checkbox = $(this).find(':checkbox');
    $checkbox[0].checked = !$checkbox[0].checked;
    $checkbox.trigger('change'); //<- Works in IE6 - IE9, Chrome, Firefox
});

Add a column for example 'Selected' First. Then Filter your data. Go to the column 'Selected'. Provide any proxy text or number to all rows. like '1' or 'A' - now your hidden Rows are Blank Now, Clear Filter and Use Sorting - two levels Sort by - 'Selected' Ascending - this leaves blank cells at bottom Add Sort Level - 'Any column you Desire' your order

Now, Why dont you drag the autofill yourself.

Oops, I have no reputation here.

I ended up abandoning the code for my other answer to this question and going with this answer instead.

I believe the best way to do this is to not use ng-show and ng-animate at all.

/* Executes jQuery slideDown and slideUp based on value of toggle-slidedown 
   attribute.  Set duration using slidedown-duration attribute.  Add the 
   toggle-required attribute to all contained form controls which are
   input, select, or textarea.  Defaults to hidden (up) if not specified
   in slidedown-init attribute.  */
fboApp.directive('toggleSlidedown', function(){
    return {
        restrict: 'A',
        link: function (scope, elem, attrs, ctrl) {
            if ('down' == attrs.slidedownInit){
                elem.css('display', '');
            } else {
                elem.css('display', 'none');
            }
            scope.$watch(attrs.toggleSlidedown, function (val) {
                var duration = _.isUndefined(attrs.slidedownDuration) ? 150 : attrs.slidedownDuration;
                if (val) {
                    elem.slideDown(duration);
                } else {
                    elem.slideUp(duration);
                }
            });
        }
    }
});

The simplest make file can be

all : test

test : test.o
        gcc -o test test.o 

test.o : test.c
        gcc -c test.c

clean :
        rm test *.o

We've used a solution based on timeGetTime in winmm.dll for millisecond accuracy for many years. See http://www.aboutvb.de/kom/artikel/komstopwatch.htm

The article is in German, but the code in the download (a VBA class wrapping the dll function call) is simple enough to use and understand without being able to read the article.

Character set conversion is done implicitly on the database connection level. You can force automatic conversion off in the ODBC or ADODB connection string with the parameter "Auto Translate=False". This is NOT recommended. See: https://msdn.microsoft.com/en-us/library/ms130822.aspx

There has been a codepage incompatibility in SQL Server 2005 when Database and Client codepage did not match. https://support.microsoft.com/kb/KbView/904803

SQL-Management Console 2008 and upwards is a UNICODE application. All values entered or requested are interpreted as such on the application level. Conversation to and from the column collation is done implicitly. You can verify this with:

SELECT CAST(N'±' as varbinary(10)) AS Result

This will return 0xB100 which is the Unicode character U+00B1 (as entered in the Management Console window). You cannot turn off "Auto Translate" for Management Studio.

If you specify a different collation in the select, you eventually end up in a double conversion (with possible data loss) as long as "Auto Translate" is still active. The original character is first transformed to the new collation during the select, which in turn gets "Auto Translated" to the "proper" application codepage. That's why your various COLLATION tests still show all the same result.

You can verify that specifying the collation DOES have an effect in the select, if you cast the result as VARBINARY instead of VARCHAR so the SQL Server transformation is not invalidated by the client before it is presented:

SELECT cast(columnName COLLATE SQL_Latin1_General_CP850_BIN2 as varbinary(10)) from tableName
SELECT cast(columnName COLLATE SQL_Latin1_General_CP1_CI_AS as varbinary(10)) from tableName

This will get you 0xF1 or 0xB1 respectively if columnName contains just the character '±'

You still might get the correct result and yet a wrong character, if the font you are using does not provide the proper glyph.

Please double check the actual internal representation of your character by casting the query to VARBINARY on a proper sample and verify whether this code indeed corresponds to the defined database collation SQL_Latin1_General_CP850_BIN2

SELECT CAST(columnName as varbinary(10)) from tableName

Differences in application collation and database collation might go unnoticed as long as the conversion is always done the same way in and out. Troubles emerge as soon as you add a client with a different collation. Then you might find that the internal conversion is unable to match the characters correctly.

All that said, you should keep in mind that Management Studio usually is not the final reference when interpreting result sets. Even if it looks gibberish in MS, it still might be the correct output. The question is whether the records show up correctly in your applications.

You may want to wrap that functionality up into a filter, this way you don't have to put the mySplit function in all of your controllers. For example

angular.module('myModule', [])
    .filter('split', function() {
        return function(input, splitChar, splitIndex) {
            // do some bounds checking here to ensure it has that index
            return input.split(splitChar)[splitIndex];
        }
    });

From here, you can use a filter as you originally intended

{{test | split:',':0}}
{{test | split:',':0}}

That's usually because you don't have a file called vertex.cpp available to make. Check that:

• that file exists.
• you're in the right directory when you make.

Other than that, I've not much else to suggest. Perhaps you could give us a directory listing of that directory.
