Programs & Examples On #Truncate log

I had this problem when I used a inner class in Post parameters

[HttpPost]
public async Task Post([FromBody] Foo value)
{
}

Where Foo is

public class Foo
{
    public IEnumerable<Bar> Bars {get;set;}

    public class Bar
    {
    }
}

Use this function to check if a string is alphanumeric:

public boolean isAlphanumeric(String str)
{
    char[] charArray = str.toCharArray();
    for(char c:charArray)
    {
        if (!Character.isLetterOrDigit(c))
            return false;
    }
    return true;
}

It saves having to import external libraries and the code can easily be modified should you later wish to perform different validation checks on strings.

You can use the top level containers root pane to set a default button, which will allow it to respond to the enter.

SwingUtilities.getRootPane(submitButton).setDefaultButton(submitButton);

This, of course, assumes you've added the button to a valid container ;)

UPDATED

This is a basic example using the JRootPane#setDefaultButton and key bindings API

public class DefaultButton {

    public static void main(String[] args) {
        new DefaultButton();
    }

    public DefaultButton() {
        EventQueue.invokeLater(new Runnable() {
            @Override
            public void run() {
                try {
                    UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
                } catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException ex) {
                }

                JFrame frame = new JFrame("Test");
                frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                frame.setLayout(new BorderLayout());
                frame.add(new TestPane());
                frame.pack();
                frame.setLocationRelativeTo(null);
                frame.setVisible(true);
            }

        });
    }

    public class TestPane extends JPanel {

        private JButton button;
        private JLabel label;
        private int count;

        public TestPane() {

            label = new JLabel("Press the button");
            button = new JButton("Press me");

            setLayout(new GridBagLayout());
            GridBagConstraints gbc = new GridBagConstraints();
            gbc.gridy = 0;
            add(label, gbc);
            gbc.gridy++;
            add(button, gbc);
            gbc.gridy++;
            add(new JButton("No Action Here"), gbc);

            button.addActionListener(new ActionListener() {
                @Override
                public void actionPerformed(ActionEvent e) {
                    doButtonPressed(e);
                }

            });

            InputMap im = button.getInputMap(WHEN_ANCESTOR_OF_FOCUSED_COMPONENT);
            ActionMap am = button.getActionMap();

            im.put(KeyStroke.getKeyStroke(KeyEvent.VK_SPACE, 0), "spaced");
            am.put("spaced", new AbstractAction() {
                @Override
                public void actionPerformed(ActionEvent e) {
                    doButtonPressed(e);
                }

            });

        }

        @Override
        public void addNotify() {
            super.addNotify();
            SwingUtilities.getRootPane(button).setDefaultButton(button);
        }

        protected void doButtonPressed(ActionEvent evt) {
            count++;
            label.setText("Pressed " + count + " times");
        }

    }

}

This of course, assumes that the component with focus does not consume the key event in question (like the second button consuming the space or enter keys

Console.OutputEncoding Property

Note that successfully displaying Unicode characters to the console requires the following:

• The console must use a TrueType font, such as Lucida Console or Consolas, to display characters.

I've recently used both Raphael and jQuery SVG - and here are my thoughts:

Raphael

Pros: a good starter library, easy to do a LOT of things with SVG quickly. Well written and documented. Lots of examples and Demos. Very extensible architecture. Great with animation.

Cons: is a layer over the actual SVG markup, makes it difficult to do more complex things with SVG - such as grouping (it supports Sets, but not groups). Doesn't do great w/ editing of already existing elements.

jQuery SVG

Pros: a jquery plugin, if you're already using jQuery. Well written and documented. Lots of examples and demos. Supports most SVG elements, allows native access to elements easily

Cons: architecture not as extensible as Raphael. Some things could be better documented (like configure of SVG element). Doesn't do great w/ editing of already existing elements. Relies on SVG semantics for animation - which is not that great.

SnapSVG as a pure SVG version of Raphael

SnapSVG is the successor of Raphael. It is supported only in the SVG enabled browsers and supports almost all the features of SVG.

Conclusion

If you're doing something quick and easy, Raphael is an easy choice. If you're going to do something more complex, I chose to use jQuery SVG because I can manipulate the actual markup significantly easier than with Raphael. And if you want a non-jQuery solution then SnapSVG is a good option.

function doSomething(element) {
  var form = element.form;
}

and in the html, you need to find that element, and add the attribut "form" to connect to that form, please refer to http://www.w3schools.com/tags/att_input_form.asp but this form attr doesn't support IE, for ie, you need to pass form id directly.

To disable a specific rule for the file:

/* eslint-disable no-use-before-define */

Note there is a bug in eslint where single line comment will not work -

// eslint-disable max-classes-per-file
// This fails!

Check this post

I really like the Broken Arrow's solution above in this post. I have just improved/changed it a bit so that what was called labels can be toggled and are not considered options. I have used a small piece of jQuery, but this could be done without jQuery.

I have replaced intermediate labels (no leaf labels) with links, which call a function on click. This function is in charge of toggling the next div of the clicked link, so that it expands/collapses the options. This avoids the possibility of selecting an intermediate element in the hierarchy, which usually is something desired. Making a variant that allows to select intermediate elements should be easy.

This is the modified html:

<div class="NestedSelect">
    <a onclick="toggleDiv(this)">Fruit</a>
    <div>
        <label>
            <input type="radio" name="MySelectInputName"><span>Apple</span></label>
        <label>
            <input type="radio" name="MySelectInputName"><span>Banana</span></label>
        <label>
            <input type="radio" name="MySelectInputName"><span>Orange</span></label>
    </div>

    <a onclick="toggleDiv(this)">Drink</a>
    <div>
        <label>
            <input type="radio" name="MySelectInputName"><span>Water</span></label>

        <a onclick="toggleDiv(this)">Soft</a>
        <div>
            <label>
                <input type="radio" name="MySelectInputName"><span>Cola</span></label>
            <label>
                <input type="radio" name="MySelectInputName"><span>Soda</span></label>
            <label>
                <input type="radio" name="MySelectInputName"><span>Lemonade</span></label>
        </div>

        <a onclick="toggleDiv(this)">Hard</a>
        <div>
            <label>
                <input type="radio" name="MySelectInputName"><span>Bear</span></label>
            <label>
                <input type="radio" name="MySelectInputName"><span>Whisky</span></label>
            <label>
                <input type="radio" name="MySelectInputName"><span>Vodka</span></label>
            <label>
                <input type="radio" name="MySelectInputName"><span>Gin</span></label>
        </div>
    </div>
</div>

A small javascript/jQuery function:

function toggleDiv(element) {
    $(element).next('div').toggle('medium');
}

And the css:

.NestedSelect {
    display: inline-block;
    height: 100%;
    border: 1px Black solid;
    overflow-y: scroll;
}

.NestedSelect a:hover, .NestedSelect span:hover  {
    background-color: #0092ff;
    color: White;
    cursor: pointer;
}

.NestedSelect input[type="radio"] {
    display: none;
}

.NestedSelect input[type="radio"] + span {
    display: block;
    padding-left: 0px;
    padding-right: 5px;
}

.NestedSelect input[type="radio"]:checked + span {
    background-color: Black;
    color: White;
}

.NestedSelect div {
    display: none;
    margin-left: 15px;
    border-left: 1px black
    solid;
}

.NestedSelect label > span:before, .NestedSelect a:before{
    content: '- ';
}

.NestedSelect a {
    display: block;
}

Here’s what you need to do:

1.Download and extract the SDK.
2.Open a terminal and navigate to the “tools” directory.
3.Launch the “android” tool (./android if you are currently in the tools directory).
4.Tick off the “SDK Platform” for each version of Android that you’d like to use in your emulator.
5.Click the “Install N Packages” button.
6.Click each package and tick off “Accept License” (legally, I’m probably required to tell you that this step may take several hours as you read each license ;).
7.Done with those licenses? Great. Click “Install”. Wait for the SDK manager to finish installing your packages, then you can close it.
8.Back in your terminal, still in the tools directory, enter ./android avd which will launch the Android Virtual Device Manager.
9.Click “New” and fill out the form to build the device you’d like to emulate. In the “Target” dropdown, you’ll see the SDK Platforms that you installed earlier. If the version you need is missing, you need to go back and install it. Click OK when you’re done.
10.Click on the device that you just created and click the “Start” button, tweak any options that you need on the Launch Options window, and click “Launch”.

You can't. Nginx doesn't really support variables in config files, and its developers mock everyone who ask for this feature to be added:

"[Variables] are rather costly compared to plain static configuration. [A] macro expansion and "include" directives should be used [with] e.g. sed + make or any other common template mechanism." http://nginx.org/en/docs/faq/variables_in_config.html

You should either write or download a little tool that will allow you to generate config files from placeholder config files.

Update The code below still works, but I've wrapped it all up into a small PHP program/library called Configurator also on Packagist, which allows easy generation of nginx/php-fpm etc config files, from templates and various forms of config data.

e.g. my nginx source config file looks like this:

location  / {
    try_files $uri /routing.php?$args;
    fastcgi_pass   unix:%phpfpm.socket%/php-fpm-www.sock;
    include       %mysite.root.directory%/conf/fastcgi.conf;
}

And then I have a config file with the variables defined:

phpfpm.socket=/var/run/php-fpm.socket
mysite.root.directory=/home/mysite

And then I generate the actual config file using that. It looks like you're a Python guy, so a PHP based example may not help you, but for anyone else who does use PHP:

<?php

require_once('path.php');

$filesToGenerate = array(
    'conf/nginx.conf' => 'autogen/nginx.conf',
    'conf/mysite.nginx.conf' => 'autogen/mysite.nginx.conf',
    'conf/mysite.php-fpm.conf' => 'autogen/mysite.php-fpm.conf',
    'conf/my.cnf' => 'autogen/my.cnf',
);

$environment = 'amazonec2';

if ($argc >= 2){
    $environmentRequired = $argv[1];

    $allowedVars = array(
        'amazonec2',
        'macports',
    );

    if (in_array($environmentRequired, $allowedVars) == true){
        $environment = $environmentRequired;
    }
}
else{
    echo "Defaulting to [".$environment."] environment";
}

$config = getConfigForEnvironment($environment);

foreach($filesToGenerate as $inputFilename => $outputFilename){
    generateConfigFile(PATH_TO_ROOT.$inputFilename, PATH_TO_ROOT.$outputFilename, $config);
}


function    getConfigForEnvironment($environment){
    $config = parse_ini_file(PATH_TO_ROOT."conf/deployConfig.ini", TRUE);
    $configWithMarkers = array();
    foreach($config[$environment] as $key => $value){
        $configWithMarkers['%'.$key.'%'] = $value;
    }

    return  $configWithMarkers;
}


function    generateConfigFile($inputFilename, $outputFilename, $config){

    $lines = file($inputFilename);

    if($lines === FALSE){
        echo "Failed to read [".$inputFilename."] for reading.";
        exit(-1);
    }

    $fileHandle = fopen($outputFilename, "w");

    if($fileHandle === FALSE){
        echo "Failed to read [".$outputFilename."] for writing.";
        exit(-1);
    }

    $search = array_keys($config);
    $replace = array_values($config);

    foreach($lines as $line){
        $line = str_replace($search, $replace, $line);
        fwrite($fileHandle, $line);
    }

    fclose($fileHandle);
}

?>

And then deployConfig.ini looks something like:

[global]

;global variables go here.

[amazonec2]
nginx.log.directory = /var/log/nginx
nginx.root.directory = /usr/share/nginx
nginx.conf.directory = /etc/nginx
nginx.run.directory  = /var/run
nginx.user           = nginx

[macports]
nginx.log.directory = /opt/local/var/log/nginx
nginx.root.directory = /opt/local/share/nginx
nginx.conf.directory = /opt/local/etc/nginx
nginx.run.directory  = /opt/local/var/run
nginx.user           = _www

smalldatetime has range up to June 6, 2079 so you can use

ORDER BY ISNULL(Next_Contact_Date, '2079-06-05T23:59:00')

If no legitimate records will have that date.

If this is not an assumption you fancy relying on a more robust option is sorting on two columns.

ORDER BY CASE WHEN Next_Contact_Date IS NULL THEN 1 ELSE 0 END, Next_Contact_Date

Both of the above suggestions are not able to use an index to avoid a sort however and give similar looking plans.

One other possibility if such an index exists is

SELECT 1 AS Grp, Next_Contact_Date 
FROM T 
WHERE Next_Contact_Date IS NOT NULL
UNION ALL
SELECT 2 AS Grp, Next_Contact_Date 
FROM T 
WHERE Next_Contact_Date IS NULL
ORDER BY Grp, Next_Contact_Date

Been looking into this for a while and not got any satisfactory answers, however...

1) ANSI escape sequences do work in a terminal on Linux

2) if you can tolerate a limited set of colo(u)rs try this:

print("hello", end=''); print("error", end='', file=sys.stderr); print("goodbye")

In idle "hello" and "goodbye" are in blue and "error" is in red.

Not fantastic, but good enough for now, and easy!

This should do:

$chunk = "abc\tdef\tghi";

Here is a link to an article with more extensive examples.

You can use different syntax to achieve different things. If it is windows authentication you want, you could try this:

sqlcmd /S  /d  -E

If you want to use SQL Server authentication you could try this:

sqlcmd /S  /d -U -P 

Definitions:

/S = the servername/instance name. Example: Pete's Laptop/SQLSERV
/d = the database name. Example: Botlek1
-E = Windows authentication.
-U = SQL Server authentication/user. Example: Pete
-P = password that belongs to the user. Example: 1234

Hope this helps!

DevSolar's answer has one point I don't understand (maybe he has a specific reason to do so, but I can't think of one): He sets the array from the positional parameters element by element, iterative.

An easier approuch would be

called_function()
{
  ...
  # do everything like shown by DevSolar
  ...

  # now get a copy of the positional parameters
  local_array=("$@")
  ...
}

Another programmatically approach;

final Button btn = (Button) findViewById(R.id.btnSize);

        final float[] size = {12};

        btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                size[0] +=2;
                btn.setTextSize(size[0] +2);
            }
        });

Every time you click your button, Button text will be change (+2px size). You can add another button and change size -2px too. If you want to save size for another openings, you may use Shared Preference interface.

Instead of getting the checked value you are setting it with:

var checked = $(this).attr('checked', true);

To properly get it:

var checked = $(this).attr('checked');

A working solution (with multiple radio buttons having different values):

// select radio buttons group (same name)
var radioButtons = $("input[type='radio'][name='rr']");
// save initial ckecked states
var radioStates = {};
$.each(radioButtons, function(index, rd) {
    radioStates[rd.value] = $(rd).is(':checked');
});

// handle click event
radioButtons.click(function() {
    
    // check/unchek radio button
    var val = $(this).val();  
    $(this).prop('checked', (radioStates[val] = !radioStates[val]));    
    
    // update other buttons checked state
    $.each(radioButtons, function(index, rd) {
        if(rd.value !== val) {
            radioStates[rd.value] = false; 
        }
    });
});

P.S.: $().attr should be used instead of $().prop for jquery < 1.6

Demo: jsFiddle

The location of jfxrt.jar in Oracle Java 7 is:

<JRE_HOME>/lib/jfxrt.jar

The location of jfxrt.jar in Oracle Java 8 is:

<JRE_HOME>/lib/ext/jfxrt.jar

The <JRE_HOME> will depend on where you installed the Oracle Java and may differ between Linux distributions and installations.

jfxrt.jar is not in the Linux OpenJDK 7 (which is what you are using).

An open source package which provides JavaFX 8 for Debian based systems such as Ubuntu is available. To install this package it is necessary to install both the Debian OpenJDK 8 package and the Debian OpenJFX package. I don't run Debian, so I'm not sure where the Debian OpenJFX package installs jfxrt.jar.

Use Oracle Java 8.

With Oracle Java 8, JavaFX is both included in the JDK and is on the default classpath. This means that JavaFX classes will automatically be found both by the compiler during the build and by the runtime when your users use your application. So using Oracle Java 8 is currently the best solution to your issue.

OpenJDK for Java 8 could include JavaFX (as JavaFX for Java 8 is now open source), but it will depend on the OpenJDK package assemblers as to whether they choose to include JavaFX 8 with their distributions. I hope they do, as it should help remove the confusion you experienced in your question and it also provides a great deal more functionality in OpenJDK.

My understanding is that although JavaFX has been included with the standard JDK since version JDK 7u6

Yes, but only the Oracle JDK.

The JavaFX version bundled with Java 7 was not completely open source so it could not be included in the OpenJDK (which is what you are using).

In you need to use Java 7 instead of Java 8, you could download the Oracle JDK for Java 7 and use that. Then JavaFX will be included with Java 7. Due to the way Oracle configured Java 7, JavaFX won't be on the classpath. If you use Java 7, you will need to add it to your classpath and use appropriate JavaFX packaging tools to allow your users to run your application. Some tools such as e(fx)clipse and NetBeans JavaFX project type will take care of classpath issues and packaging tasks for you.

Use

System.getProperty("java.class.path")

see http://docs.oracle.com/javase/tutorial/essential/environment/sysprop.html

You can also split it into it's elements easily

String classpath = System.getProperty("java.class.path");
String[] classpathEntries = classpath.split(File.pathSeparator);

In order to have completely custom facebook login button without using com.facebook.widget.LoginButton.

According to facebook sdk 4.x,

There new concept of login as from facebook

LoginManager and AccessToken - These new classes perform Facebook Login

So, Now you can access Facebook authentication without Facebook login button as

layout.xml

    <Button
            android:id="@+id/btn_fb_login"
            .../>

MainActivity.java

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        FacebookSdk.sdkInitialize(this.getApplicationContext());

        callbackManager = CallbackManager.Factory.create();

        LoginManager.getInstance().registerCallback(callbackManager,
                new FacebookCallback<LoginResult>() {
                    @Override
                    public void onSuccess(LoginResult loginResult) {
                        Log.d("Success", "Login");

                    }

                    @Override
                    public void onCancel() {
                        Toast.makeText(MainActivity.this, "Login Cancel", Toast.LENGTH_LONG).show();
                    }

                    @Override
                    public void onError(FacebookException exception) {
                        Toast.makeText(MainActivity.this, exception.getMessage(), Toast.LENGTH_LONG).show();
                    }
                });

        setContentView(R.layout.activity_main);

        Button btn_fb_login = (Button)findViewById(R.id.btn_fb_login);

        btn_fb_login.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                  LoginManager.getInstance().logInWithReadPermissions(MainActivity.this, Arrays.asList("public_profile", "user_friends"));
            }
        });

    }

@Override 
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    callbackManager.onActivityResult(requestCode, resultCode, data); 
}

"line 1\nline 2\r\n...".replace('\n', '').replace('\r', '')
>>> 'line 1line 2...'

or you could always get geekier with regexps :)

have fun!

In C++ NULL expands to 0 or 0L. See this quote from Stroustrup's FAQ:

Should I use NULL or 0?

In C++, the definition of NULL is 0, so there is only an aesthetic difference. I prefer to avoid macros, so I use 0. Another problem with NULL is that people sometimes mistakenly believe that it is different from 0 and/or not an integer. In pre-standard code, NULL was/is sometimes defined to something unsuitable and therefore had/has to be avoided. That's less common these days.

If you have to name the null pointer, call it nullptr; that's what it's called in C++11. Then, "nullptr" will be a keyword.

You need to store it in a String variable first before displaying it like so:

String Txt = TxtBoxContent.getText();
System.out.println(Txt);

Looks like whatever is in your Animation Drawable definition is too much memory to decode and sequence. The idea is that it loads up all the items and make them in an array and swaps them in and out of the scene according to the timing specified for each frame.

If this all can't fit into memory, it's probably better to either do this on your own with some sort of handler or better yet just encode a movie with the specified frames at the corresponding images and play the animation through a video codec.

If you get Cannot redirect after HTTP headers have been sent then try this below code.

HttpContext.Current.Server.ClearError();
// Response.Headers.Clear();
HttpContext.Current.Response.Redirect("/Home/Login",false);

So at first I was tempted to return my application error with 200 OK and a specific XML payload (ie. Pay us more and you'll get the storage you need!) but I stopped to think about it and it seems to soapy (/shrug in horror).

I wouldn't return a 200 unless there really was nothing wrong with the request. From RFC2616, 200 means "the request has succeeded."

If the client's storage quota has been exceeded (for whatever reason), I'd return a 403 (Forbidden):

The server understood the request, but is refusing to fulfill it. Authorization will not help and the request SHOULD NOT be repeated. If the request method was not HEAD and the server wishes to make public why the request has not been fulfilled, it SHOULD describe the reason for the refusal in the entity. If the server does not wish to make this information available to the client, the status code 404 (Not Found) can be used instead.

This tells the client that the request was OK, but that it failed (something a 200 doesn't do). This also gives you the opportunity to explain the problem (and its solution) in the response body.

What other specific error conditions did you have in mind?

I had to do this with text fields and came across the limit of 100 bytes on the index.

I solved this by adding a column, doing a md5 hash of the fields, and the doing the alter.

ALTER TABLE table ADD `merged` VARCHAR( 40 ) NOT NULL ;
UPDATE TABLE SET merged` = MD5(CONCAT(`col1`, `col2`, `col3`))
ALTER IGNORE TABLE table ADD UNIQUE INDEX idx_name (`merged`);

System.out.println("hello"+"\n"+"world");

I just discovered the Hmisc package:

Contains many functions useful for data analysis, high-level graphics, utility operations, functions for computing sample size and power, importing and annotating datasets, imputing missing values, advanced table making, variable clustering, character string manipulation, conversion of R objects to LaTeX and html code, and recoding variables.

Wikipedia has us covered:

In computer science, overhead is generally considered any combination of excess or indirect computation time, memory, bandwidth, or other resources that are required to attain a particular goal. It is a special case of engineering overhead.

After some action the namespace of the .cs file and the one in .xaml file may be different (in xaml look for the x:Class="namespace.yourType").

Fix them to be the same.

Another way that this can unfold, and just did for me, is if you have a build error that Eclipse doesn't tell you about. If compiling the unit test fails then there is no .class file and you will get the ClassNotFoundException.

In my case there was a missing 3rd party jar file. When I ran the test I got a pop-up window that said "Errors exist in required project(s)". I work with a huge project and I always get that message because some of the source is not available to eclipse (long story). Also it doesn't say what the errors are. So I click "Continue" and then I get the exception.

Once I realized what was going on it was easy to fix by adding the missing jar to the classpath under Run -> Debug Configurations...

I'm not sure how to best detect or prevent this from happening except to be aware of this possibility when something goes wrong and to review your most recent changes for what might have gone wrong.

Something like this works:

input + label::after {_x000D_
  content: 'click my input';_x000D_
  color: black;_x000D_
}_x000D_
_x000D_
input:focus + label::after {_x000D_
  content: 'not valid yet';_x000D_
  color: red;_x000D_
}_x000D_
_x000D_
input:valid + label::after {_x000D_
  content: 'looks good';_x000D_
  color: green;_x000D_
}

<input id="input" type="number" required />_x000D_
<label for="input"></label>

Then add some floats or positioning to order stuff.

Here's another variation on the technique, similar to Bjorn's (apphacker), which lets you assign the variable value inside the function rather than passing it as a parameter, which might be clearer sometimes:

var funcs = [];_x000D_
for (var i = 0; i < 3; i++) {_x000D_
    funcs[i] = (function() {_x000D_
        var index = i;_x000D_
        return function() {_x000D_
            console.log("My value: " + index);_x000D_
        }_x000D_
    })();_x000D_
}

Note that whatever technique you use, the index variable becomes a sort of static variable, bound to the returned copy of the inner function. I.e., changes to its value are preserved between calls. It can be very handy.

Here is what I do to avoid the issues of making the remote server accept your local external IP:

• when I ssh into the machine, I use the option -L to transfer the port 6006 of the remote server into the port 16006 of my machine (for instance): ssh -L 16006:127.0.0.1:6006 olivier@my_server_ip

What it does is that everything on the port 6006 of the server (in 127.0.0.1:6006) will be forwarded to my machine on the port 16006.

• You can then launch tensorboard on the remote machine using a standard tensorboard --logdir log with the default 6006port
• On your local machine, go to http://127.0.0.1:16006 and enjoy your remote TensorBoard.

[function.fopen]: failed to open stream

If you have access to your php.ini file, try enabling Fopen. Find the respective line and set it to be "on": & if in wp e.g localhost/wordpress/function.fopen in the php.ini :

allow_url_fopen = off
should bee this 
allow_url_fopen = On

And add this line below it:
allow_url_include = off
should bee this 
allow_url_include = on

with 5 columns and colspan, this is possible (click here) (but doesn't make much sense to me):

<table width="100%" border="1" bgcolor="#ffffff">
    <colgroup>
        <col width="25%">
        <col width="25%">
        <col width="25%">
        <col width="5%">
        <col width="20%">
    </colgroup>
    <tr>
        <td>25</td>
        <td colspan="2">50</td>
        <td colspan="2">25</td>     
    </tr>
    <tr>
        <td colspan="2">50</td>
        <td colspan="2">30</td>
        <td>20</td>
    </tr>
</table>

You can use numpy.shape.

import numpy as np
x = np.array([[1, 2],[3, 4],[5, 6]])

Result:

>>> x
array([[1, 2],
       [3, 4],
       [5, 6]])
>>> np.shape(x)
(3, 2)

First value in the tuple is number rows = 3; second value in the tuple is number of columns = 2.

Add this below dependency in your pom.xml

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-web</artifactId>
</dependency>

This is used for @RestController, @RequestMapping

You might have been having the same problem I was initially having. I was trying to use FormData to grab all my input files to upload an image, but at the same time I wanted to append a session ID to the information passed along to the server. All this time, I thought by appending the information, you would be able to see it in the server by accessing the object. I was wrong. When you append to FormData, the way to check the appended information on the server is by a simple $_POST['*your appended data*'] query. like so:

js:

$('form').submit(function(){
    var sessionID = 8;
    var formData = new FormData(this);
    formData.append('id', sessionID);

    $.ajax({
        url: "yoururl.php",
        data: formData,
        processData: false,
        contentType: false,
        type: 'POST',
        success: function(data){
            alert(data);
        }
    });
});

then on php:

$sessionID = $_POST['id'];
$files = $_FILES['image'];

$foreach ($files as $key=>val){
    //...
}

Two different ways I got this working.

Option 1: Add these 3 <script> tags to your .html file, just before the closing </body> tag:

<script src="https://code.jquery.com/jquery-3.2.1.slim.min.js" integrity="sha384-KJ3o2DKtIkvYIK3UENzmM7KCkRr/rE9/Qpg6aAZGJwFDMVNA/GpGFF93hXpG5KkN" crossorigin="anonymous"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.12.9/umd/popper.min.js" integrity="sha384-ApNbgh9B+Y1QKtv3Rn7W3mgPxhU9K/ScQsAP7hUibX39j7fakFPskvXusvfa0b4Q" crossorigin="anonymous"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/js/bootstrap.min.js" integrity="sha384-JZR6Spejh4U02d8jOt6vLEHfe/JQGiRRSQQxSfFWpi1MquVdAyjUar5+76PVCmYl" crossorigin="anonymous"></script> 

Option 2 (Option 2 works with Angular, not sure about other frameworks)

Step 1: Install the 3 libraries using NPM:

npm install bootstrap --save

npm install popper.js --save

npm install jquery --save

Step 2: Update the script: array(s) in your angular.json file like this:

"scripts": ["node_modules/jquery/dist/jquery.min.js", "node_modules/popper.js/dist/umd/popper.min.js", "node_modules/bootstrap/dist/js/bootstrap.min.js"]

i use below log format for print my content in logCat

Log.e("Msg","What you have to print");

There are multiple problems here

1. Id should be unique in a page
2. For dynamic elements, you need to use event delegation using .on()

Ex

$(document).ready(function(){
    $("#addCF").click(function(){
        $("#customFields").append('<tr valign="top"><th scope="row"><label for="customFieldName">Custom Field</label></th><td><input type="text" class="code" id="customFieldName" name="customFieldName[]" value="" placeholder="Input Name" /> &nbsp; <input type="text" class="code" id="customFieldValue" name="customFieldValue[]" value="" placeholder="Input Value" /> &nbsp; <a href="javascript:void(0);" id="remCF">Remove</a></td></tr>');
    });

    $("#customFields").on('click', '#remCF', function(){
        $(this).parent().parent().remove();
    });

});

Demo: Fiddle

See this demo where id properties are removed.

$(document).ready(function(){
    $("#addCF").click(function(){
        $("#customFields").append('<tr valign="top"><th scope="row"><label for="customFieldName">Custom Field</label></th><td><input type="text" class="code" name="customFieldName[]" value="" placeholder="Input Name" /> &nbsp; <input type="text" class="code" name="customFieldValue[]" value="" placeholder="Input Value" /> &nbsp; <a href="javascript:void(0);" class="remCF">Remove</a></td></tr>');
    });

    $("#customFields").on('click', '.remCF', function(){
        $(this).parent().parent().remove();
    });

});

According to the Documentation :

MailMessage.To property - Returns MailAddressCollection that contains the list of recipients of this email message

Here MailAddressCollection has a in built method called

   public void Add(string addresses)

   1. Summary:
          Add a list of email addresses to the collection.

   2. Parameters:
          addresses: 
                *The email addresses to add to the System.Net.Mail.MailAddressCollection. Multiple
                *email addresses must be separated with a comma character (",").     

Therefore requirement in case of multiple recipients : Pass a string that contains email addresses separated by comma

In your case :

simply replace all the ; with ,

Msg.To.Add(toEmail.replace(";", ","));

For reference :

To combine revision 3 and 4 into a single revision, you can use git rebase. If you want to remove the changes in revision 3, you need to use the edit command in the interactive rebase mode. If you want to combine the changes into a single revision, use squash.

I have successfully used this squash technique, but have never needed to remove a revision before. The git-rebase documentation under "Splitting commits" should hopefully give you enough of an idea to figure it out. (Or someone else might know).

From the git documentation:

Start it with the oldest commit you want to retain as-is:

git rebase -i <after-this-commit>

An editor will be fired up with all the commits in your current branch (ignoring merge commits), which come after the given commit. You can reorder the commits in this list to your heart's content, and you can remove them. The list looks more or less like this:

pick deadbee The oneline of this commit
pick fa1afe1 The oneline of the next commit
...

The oneline descriptions are purely for your pleasure; git-rebase will not look at them but at the commit names ("deadbee" and "fa1afe1" in this example), so do not delete or edit the names.

By replacing the command "pick" with the command "edit", you can tell git-rebase to stop after applying that commit, so that you can edit the files and/or the commit message, amend the commit, and continue rebasing.

If you want to fold two or more commits into one, replace the command "pick" with "squash" for the second and subsequent commit. If the commits had different authors, it will attribute the squashed commit to the author of the first commit.

In Ubuntu or any other platform (yes, Windows too!); starting git1.8.4, which was released 2013-08-23, you won't have to do anything:

Many tutorials teach users to set "color.ui" to "auto" as the first thing after you set "user.name/email" to introduce yourselves to Git. Now the variable defaults to "auto".

So you will see colors by default.

SQL Plus will format the columns to hold the maximum possible value, which in this case is 255 characters.

To confirm that your output does not actually contain those extra spaces, try this:

SELECT
  '/' || TRIM(A) || '/' AS COLUMN_A
 ,'/' || TRIM(B) || '/' AS COLUMN_B
FROM
  MY_TABLE;

If the '/' characters are separated from your output, then that indicates that it's not spaces, but some other whitespace character that got in there (tabs, for example). If that is the case, then it is probably an input validation issue somewhere in your application.

However, the most likely scenario is that the '/' characters will in fact touch the rest of your strings, thus proving that the whitespace is actually trimmed.

If you wish to output them together, then the answer given by Quassnoi should do it.

If it is purely a display issue, then the answer given by Tony Andrews should work fine.

Here is a tidyverse option that might not the most elegant, but offers some flexibility in terms of what is included in the summary:

library(tidyverse)
dir_path <- '~/path/to/data/directory/'
file_pattern <- 'Df\\.[0-9]\\.csv' # regex pattern to match the file name format

read_dir <- function(dir_path, file_name){
  read_csv(paste0(dir_path, file_name)) %>% 
    mutate(file_name = file_name) %>%                # add the file name as a column              
    gather(variable, value, A:B) %>%                 # convert the data from wide to long
    group_by(file_name, variable) %>% 
    summarize(sum = sum(value, na.rm = TRUE),
              min = min(value, na.rm = TRUE),
              mean = mean(value, na.rm = TRUE),
              median = median(value, na.rm = TRUE),
              max = max(value, na.rm = TRUE))
  }

df_summary <- 
  list.files(dir_path, pattern = file_pattern) %>% 
  map_df(~ read_dir(dir_path, .))

df_summary
# A tibble: 8 x 7
# Groups:   file_name [?]
  file_name variable   sum   min  mean median   max
  <chr>     <chr>    <int> <dbl> <dbl>  <dbl> <dbl>

2 Df.1.csv  B           22     1  3.67    3       9
3 Df.2.csv  A           21     1  3.5     3.5     6
4 Df.2.csv  B           16     1  2.67    2.5     5
5 Df.3.csv  A           30     0  5       5      11

7 Df.4.csv  A           21     0  3.5     3       8
8 Df.4.csv  B           42     1  7       6      16

If number could be None or a number, and you wanted to include 0, filter on None instead:

if number is not None:

If number can be any number of types, test for the type; you can test for just int or a combination of types with a tuple:

if isinstance(number, int):  # it is an integer
if isinstance(number, (int, float)):  # it is an integer or a float

or perhaps:

from numbers import Number

if isinstance(number, Number):

to allow for integers, floats, complex numbers, Decimal and Fraction objects.

In Java 8 you can use lambda expressions with the Concurrency API & the ExecutorService as a higher level replacement for working with threads directly:

newCachedThreadPool() Creates a thread pool that creates new threads as needed, but will reuse previously constructed threads when they are available. These pools will typically improve the performance of programs that execute many short-lived asynchronous tasks.

    private static final ExecutorService executor = Executors.newCachedThreadPool();

    executor.submit(() -> {
        myFunction(myParam1, myParam2);
    });

See also executors javadocs.

Here is what you need to do. First make sure you are in branch that you don't want to pull. For example if you have master and develop branch, and you are trying to pull develop branch then stay in master branch.

git checkout master

Then,

git pull origin develop

Now you can upgrade to PHP7.4 and MySQL will go with caching_sha2_password by default, so default MySQL installation will work with mysqli_connect No configuration required.

Here is a function that I use for looping over an array:

function loopOnArrayWithDelay(theArray, delayAmount, i, theFunction, onComplete){

    if (i < theArray.length && typeof delayAmount == 'number'){

        console.log("i "+i);

        theFunction(theArray[i], i);

        setTimeout(function(){

            loopOnArrayWithDelay(theArray, delayAmount, (i+1), theFunction, onComplete)}, delayAmount);
    }else{

        onComplete(i);
    }
}

You use it like this:

loopOnArrayWithDelay(YourArray, 1000, 0, function(e, i){
    //Do something with item
}, function(i){
    //Do something once loop has completed
}

I agree with John Saunders, this isn't really C# specific. However, to answer your question: you basically need to rewrite the file. There are two ways you can do this.

• Read the whole file into memory (e.g. with File.ReadAllLines)
• Remove the offending line (in this case it's probably easiest to convert the string array into a List<string> then remove the line)
• Write all the rest of the lines back (e.g. with File.WriteAllLines) - potentially convert the List<string> into a string array again using ToArray

That means you have to know that you've got enough memory though. An alternative:

• Open both the input file and a new output file (as a TextReader/TextWriter, e.g. with File.OpenText and File.CreateText)
• Read a line (TextReader.ReadLine) - if you don't want to delete it, write it to the output file (TextWriter.WriteLine)
• When you've read all the lines, close both the reader and the writer (if you use using statements for both, this will happen automatically)
• If you want to replace the input with the output, delete the input file and then move the output file into place.

There are two commands which will work in this situation,

root>git reset --hard HEAD~1

root>git push -f

For more git commands refer this page

Including "string.h" makes things easier. An easier way to tackle your problem is:

#include <string.h>
    char* createStr(){
    static char str[20] = "my";
    return str;
}
int main(){
    char a[20];
    strcpy(a,createStr()); //this will copy the returned value of createStr() into a[]
    printf("%s",a);
    return 0;
}

For me, when typing the url, a user accidentally used a / instead of a ? to start the query parameters

e.g.:

url.com/endpoint/parameter=SomeValue&otherparameter=Another+value

which should have been:

url.com/endpoint?parameter=SomeValue&otherparameter=Another+value

May help to someone:

    router.HandleFunc("/login", Login.Login).Methods("POST")

    log.Fatal(http.ListenAndServe(":3001", router))
}

Login.go,

    data, err := ioutil.ReadAll(r.Body)

    if err == nil {
        err := json.Unmarshal(data, &user)
        if err == nil {
            user = Postgres.GetUser(user.UserName, user.Password)
            w.Header().Set("Access-Control-Allow-Origin", "*")
            json.NewEncoder(w).Encode(user)
        }
    }
}

I use zsh-autoenv which is based off autoenv.

zsh-autoenv automatically sources (known/whitelisted) .autoenv.zsh files, typically used in project root directories. It handles "enter" and leave" events, nesting, and stashing of variables (overwriting and restoring).

Here is an example:

; cd dtree 
Switching to virtual environment: Development tree utiles
;dtree(feature/task24|?); cat .autoenv.zsh       
# Autoenv.
echo -n "Switching to virtual environment: "
printf "\e[38;5;93m%s\e[0m\n" "Development tree utiles"
workon dtree
# eof
dtree(feature/task24|?); cat .autoenv_leave.zsh 
deactivate

So when I leave the dtree directory, the virtual environment is automatically exited.

"Development tree utiles" is just a name… No hidden mean linking to the Illuminati in here.

dup2( STDIN_FILENO, newfd )

And read:

char reading[ 1025 ];
int fdin = 0, r_control;
if( dup2( STDIN_FILENO, fdin ) < 0 ){
    perror( "dup2(  )" );
    exit( errno );
}
memset( reading, '\0', 1025 );
while( ( r_control = read( fdin, reading, 1024 ) ) > 0 ){
    printf( "<%s>", reading );
    memset( reading, '\0', 1025 );
}
if( r_control < 0 )
    perror( "read(  )" );    
close( fdin );    

But, I think that fcntl can be a better solution

echo "salut" | code

Yes, you can. By specifying the object_pairs_hook argument to JSONDecoder. In fact, this is the exact example given in the documentation.

>>> json.JSONDecoder(object_pairs_hook=collections.OrderedDict).decode('{"foo":1, "bar": 2}')
OrderedDict([('foo', 1), ('bar', 2)])
>>> 

You can pass this parameter to json.loads (if you don't need a Decoder instance for other purposes) like so:

>>> import json
>>> from collections import OrderedDict
>>> data = json.loads('{"foo":1, "bar": 2}', object_pairs_hook=OrderedDict)

Using json.load is done in the same way:

>>> data = json.load(open('config.json'), object_pairs_hook=OrderedDict)

In my recent tests with IE8 and Firefox 3.5, it seems that both are RFC-compliant. However, they differ in their "friendliness" to the origin server. IE8 treats no-cache responses with the same semantics as max-age=0,must-revalidate. Firefox 3.5, however, seems to treat no-cache as equivalent to no-store, which sucks for performance and bandwidth usage.

Squid Cache, by default, seems to never store anything with a no-cache header, just like Firefox.

My advice would be to set public,max-age=0 for non-sensitive resources you want to have checked for freshness on every request, but still allow the performance and bandwidth benefits of caching. For per-user items with the same consideration, use private,max-age=0.

I would avoid the use of no-cache entirely, as it seems it has been bastardized by some browsers and popular caches to the functional equivalent of no-store.

Additionally, do not emulate Akamai and Limelight. While they essentially run massive caching arrays as their primary business, and should be experts, they actually have a vested interest in causing more data to be downloaded from their networks. Google might not be a good choice for emulation, either. They seem to use max-age=0 or no-cache randomly depending on the resource.

        var response = await client.PostAsync("http://YourSite.com/api/apiTables", httpContent);

        str = "" + response.Content + " : " + response.StatusCode;

        if (response.IsSuccessStatusCode)

After making changes to the pg_hba.conf or postgresql.conf files, the cluster needs to be reloaded to pick up the changes.

From the command line: pg_ctl reload

From within a db (as superuser): select pg_reload_conf();

From PGAdmin: right-click db name, select "Reload Configuration"

Note: the reload is not sufficient for changes like enabling archiving, changing shared_buffers, etc -- those require a cluster restart.

Or you can use the more obvious solution, right in the GUI: Tools -> Messages (set verbosity to 2)...

I had the same error, but I had it fixed by modifying the php.ini and / or editing the PHP file!

There are two different methods to get around the parse error syntax.

Method 1 (Your PHP file)

Avoid in your PHP file this:

<? } ?>

Make sure you put it like this

<?php ?>

Your code contains <? ?>

NOTE: The missing php after <?!

Method 2 (php.ini file)

There is also a simple way to solve your problem. Search for the short_open_tag property value (Use in your text editor with Ctrl + F!), and apply the following change:

; short_open_tag = Off

to

short_open_tag = On

According to the description of core php.ini directives, short_open_tag allows you to use the short open tag (<?) although this might cause issues when used with xml (<?xml will not work when this is enabled)!

NOTE: Reload your Server (like for example: Apache) and reload your PHP webpage in your browser.

There seems to be a lot of confusion here. The answers I see so far don't correctly enforce the 1+ number/1+ lowercase/1+ uppercase rule, meaning that passwords like abc123, 123XYZ, or AB*&^# would still be accepted. Preventing all-lowercase, all-caps, or all-digits is not enough; you have to enforce the presence of at least one of each.

Try the following:

^(?=.*[a-z])(?=.*[A-Z])(?=.*\d).{8,15}$

If you also want to require at least one special character (which is probably a good idea), try this:

^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)(?=.*[^\da-zA-Z]).{8,15}$

The .{8,15} can be made more restrictive if you wish (for example, you could change it to \S{8,15} to disallow whitespace), but remember that doing so will reduce the strength of your password scheme.

I've tested this pattern and it works as expected. Tested on ReFiddle here: http://refiddle.com/110

Edit: One small note, the easiest way to do this is with 3 separate regexes and the string's Length property. It's also easier to read and maintain, so do it that way if you have the option. If this is for validation rules in markup, though, you're probably stuck with a single regex.

I fixed this problem with sql command line:

connect system/<password>
alter system set processes=300 scope=spfile;
alter system set sessions=300 scope=spfile;

Restart database.

I have recently encountered the same issue and hopefully what follows will be helpful. In Windows, the default program for opening .eml files is set to Outlook. Every user of Lotus notes should take the steps to have .eml files defaulted to open via Lotus notes.

Start menu--- Defaults programs---Lotus notes-- and check .eml--- then save.

After performing this, Lotus notes will be the default to open these attachments.

I got the same:

ALTER TABLE DROP COLUMN failed because one or more objects access this column message.

My column had an index which needed to be deleted first. Using sys.indexes did the trick:

DECLARE @sql VARCHAR(max)

SELECT @sql = 'DROP INDEX ' + idx.NAME + ' ON tblName'
FROM sys.indexes idx
INNER JOIN sys.tables tbl ON idx.object_id = tbl.object_id
INNER JOIN sys.index_columns idxCol ON idx.index_id = idxCol.index_id
INNER JOIN sys.columns col ON idxCol.column_id = col.column_id
WHERE idx.type <> 0
    AND tbl.NAME = 'tblName'
    AND col.NAME = 'colName'

EXEC sp_executeSql @sql
GO

ALTER TABLE tblName
DROP COLUMN colName

Use the str.isspace() method:

Return True if there are only whitespace characters in the string and there is at least one character, False otherwise.

A character is whitespace if in the Unicode character database (see unicodedata), either its general category is Zs (“Separator, space”), or its bidirectional class is one of WS, B, or S.

Combine that with a special case for handling the empty string.

Alternatively, you could use str.strip() and check if the result is empty.

There's no problem. I would even remove the CreateNewOrUpdateExisting from the source and use map[key] = value directly in your code, because this this is much more readable, because developers would usually know what map[key] = value means.

Don't use read without arguments. It's very slow. Better read it to buffer and move it to file quickly.

Use bufferedInputStream because it supports binary reading.

And it's all.

if my_list is the list that you want to store your objects in it and my_object is your object wanted to be stored, use this structure:

my_list.append(my_object)

use keyof typeof

const cat = {
    name: 'tuntun'
}

const key: string = 'name' 

cat[key as keyof typeof cat]

A clone is where you have proper duplication, and separation between, two (possibly different) versions of a repository. When one repo is amended, the new content must be actively copied to the other repo using a push command. And changes in the other repo fetched.

When you fork a repo, on a server, there is no need for duplication of content because both repos will use the same [fixed object] content from that same server. The 'trick' is in managing the different user viewpoints so that each user believes they have a full personal copy of the repo. Pushes and fetches between forks is simply updates the user's pointers.

At a lower level, git does the same thing internally. If you have three different files, each containing Hello World, then git simply 'forks' its single copy of the Hello World blob and offers it up in each of the three places as required.

The ability to fork on the server means that Github's large storage allowance isn't that big on average as every body shares the one single underlying repo.

The first constructor in the header should not end with a semicolon. #include <string> is missing in the header. string is not qualified with std:: in the .cpp file. Those are all simple syntax errors. More importantly: you are not using references, when you should. Also the way you use the ifstream is broken. I suggest learning C++ before trying to use it.

Let's fix this up:

//polygone.h
# if !defined(__POLYGONE_H__)
# define __POLYGONE_H__

#include <iostream>
#include <string>    

class Polygone {
public:
  // declarations have to end with a semicolon, definitions do not
  Polygone(){} // why would we needs this?
  Polygone(const std::string& fichier);
};

# endif

and

//polygone.cc
// no need to include things twice
#include "polygone.h"
#include <fstream>


Polygone::Polygone(const std::string& nom)
{
  std::ifstream fichier (nom, ios::in);


  if (fichier.is_open())
  {
    // keep the scope as tiny as possible
    std::string line;
    // getline returns the stream and streams convert to booleans
    while ( std::getline(fichier, line) )
    {
      std::cout << line << std::endl;
    }
  }
  else
  {
    std::cerr << "Erreur a l'ouverture du fichier" << std::endl;
  }
}

Just a speculation, I have not enough experience to try it... )-:

Since GoogleMap is a fragment, it should be possible to catch marker onClick event and show custom fragment view. A map fragment will be still visible on the background. Does anybody tried it? Any reason why it could not work?

The disadvantage is that map fragment would be freezed on backgroud, until a custom info fragment return control to it.

grep $PATTERN * would be sufficient. By default, grep would skip all subdirectories. However, if you want to grep through them, grep -r $PATTERN * is the case.

PID is the process ID - not the port number. You need to look for an entry with ":8080" at the end of the address/port part (the second column). Then you can look at the PID and use Task Manager to work out which process is involved... or run netstat -abn which will show the process names (but must be run under an administrator account).

Having said that, I would expect the find "8080" to find it...

Another thing to do is just visit http://localhost:8080 - on that port, chances are it's a web server of some description.

String str = "wwwwww3333dfevvv";
char[] c = str.toCharArray();

Now to convert character array into String , there are two ways.

Arrays.toString(c);

Returns the string [w, w, w, w, w, w, 3, 3, 3, 3, d, f, e, v, v, v].

And:

String.valueOf(c)

Returns the string wwwwww3333dfevvv.

In Summary: pay attention to Arrays.toString(c), because you'll get "[w, w, w, w, w, w, 3, 3, 3, 3, d, f, e, v, v, v]" instead of "wwwwww3333dfevvv".

In addition to Nick Holt's observations, I ran a few cases for Array data type:

//primitive Array
int demo[] = new int[5];
Class<? extends int[]> clzz = demo.getClass();
System.out.println(clzz.getName());
System.out.println(clzz.getCanonicalName());
System.out.println(clzz.getSimpleName());       

System.out.println();


//Object Array
Integer demo[] = new Integer[5]; 
Class<? extends Integer[]> clzz = demo.getClass();
System.out.println(clzz.getName());
System.out.println(clzz.getCanonicalName());
System.out.println(clzz.getSimpleName());

Above code snippet prints:

[I
int[]
int[]

[Ljava.lang.Integer;
java.lang.Integer[]
Integer[]

One can always go for analytical functions as well which will give you more control

select tmp.row from ( select row, rank() over(partition by id order by id desc ) as rnk from table) tmp where tmp.rnk=1

If you face issue with rank() function depending on the type of data then one can choose from row_number() or dense_rank() too.

You can also use the suggested error message as a hint. Here's how, find the Manage Packages for Solution, and click on the resolve missing nuget package.

That's it

$('#thedate,#dateid').datepicker({
     changeMonth:true,
         changeYear:true,
         yearRange:"-100:+0",
         dateFormat:"dd/mm/yy" ,
         maxDate: '0',
     });
});

In Excel for Mac 2016 at least,if you place the labels in any spot on the graph and are looking to move them anywhere else (in this case above the bars), select:

Chart Design->Add Chart Element->Data Labels -> More Data Label Options

then you can grab each individual label and pull it where you would like it.

You can pass you session variables from your php script to JQUERY using JSON such as

JS:

jQuery("#rowed2").jqGrid({
    url:'yourphp.php?q=3', 
    datatype: "json", 
    colNames:['Actions'], 
    colModel:[{
                name:'Actions',
                index:'Actions', 
                width:155,
                sortable:false
              }], 
    rowNum:30, 
    rowList:[50,100,150,200,300,400,500,600], 
    pager: '#prowed2', 
    sortname: 'id',
    height: 660,        
    viewrecords: true, 
    sortorder: 'desc',
    gridview:true,
    editurl: 'yourphp.php', 
    caption: 'Caption', 
    gridComplete: function() { 
        var ids = jQuery("#rowed2").jqGrid('getDataIDs'); 
        for (var i = 0; i < ids.length; i++) { 
            var cl = ids[i]; 
            be = "<input style='height:22px;width:50px;' `enter code here` type='button' value='Edit' onclick=\"jQuery('#rowed2').editRow('"+cl+"');\" />"; 
            se = "<input style='height:22px;width:50px;' type='button' value='Save' onclick=\"jQuery('#rowed2').saveRow('"+cl+"');\" />"; 
            ce = "<input style='height:22px;width:50px;' type='button' value='Cancel' onclick=\"jQuery('#rowed2').restoreRow('"+cl+"');\" />"; 
            jQuery("#rowed2").jqGrid('setRowData', ids[i], {Actions:be+se+ce}); 
        } 
    }
}); 

PHP

// start your session
session_start();

// get session from database or create you own
$session_username = $_SESSION['John'];
$session_email = $_SESSION['[email protected]'];

$response = new stdClass();
$response->session_username = $session_username;
$response->session_email = $session_email;

$i = 0;
while ($row = mysqli_fetch_array($result)) { 
    $response->rows[$i]['id'] = $row['ID']; 
    $response->rows[$i]['cell'] = array("", $row['rowvariable1'], $row['rowvariable2']); 
    $i++; 
} 

echo json_encode($response);
// this response (which contains your Session variables) is sent back to your JQUERY 

An other approach is to use splice.

The splice() method changes the contents of an array by removing or replacing existing elements and/or adding new elements in place.

N.B : In case you're working with reactive frameworks, it will update the "view", your array "knowing" you've updated it.

Answer :

var item = {...}
var items = [{id:2}, {id:2}, {id:2}];

let foundIndex = items.findIndex(element => element.id === item.id)
items.splice(foundIndex, 1, item)

And in case you want to only change a value of an item, you can use find function :

// Retrieve item and assign ref to updatedItem
let updatedItem = items.find((element) => { return element.id === item.id })

// Modify object property
updatedItem.aProp = ds.aProp

There are at least three places where you may find shared_ptr:

1. If your C++ implementation supports C++11 (or at least the C++11 shared_ptr), then std::shared_ptr will be defined in <memory>.

2. If your C++ implementation supports the C++ TR1 library extensions, then std::tr1::shared_ptr will likely be in <memory> (Microsoft Visual C++) or <tr1/memory> (g++'s libstdc++). Boost also provides a TR1 implementation that you can use.

3. Otherwise, you can obtain the Boost libraries and use boost::shared_ptr, which can be found in <boost/shared_ptr.hpp>.

No, you can't. JavaScript is executed on the client side (browser), while the session data is stored on the server.

However, you can expose session variables for JavaScript in several ways:

• a hidden input field storing the variable as its value and reading it through the DOM API
• an HTML5 data attribute which you can read through the DOM
• storing it as a cookie and accessing it through JavaScript
• injecting it directly in the JS code, if you have it inline

In JSP you'd have something like:

<input type="hidden" name="pONumb" value="${sessionScope.pONumb} />

or:

<div id="product" data-prodnumber="${sessionScope.pONumb}" />

Then in JS:

// you can find a more efficient way to select the input you want
var inputs = document.getElementsByTagName("input"), len = inputs.length, i, pONumb;
for (i = 0; i < len; i++) {
    if (inputs[i].name == "pONumb") {
        pONumb = inputs[i].value;
        break;
    }
}

or:

var product = document.getElementById("product"), pONumb;
pONumb = product.getAttribute("data-prodnumber");

The inline example is the most straightforward, but if you then want to store your JavaScript code as an external resource (the recommended way) it won't be feasible.

<script>
    var pONumb = ${sessionScope.pONumb};
    [...]
</script>

Setting expect 100 continue to false and reducing the socket idle time to two seconds resolved the problem for me

ServicePointManager.Expect100Continue = false; 
ServicePointManager. MaxServicePointIdleTime = 2000; 

The alignment-baseline property is what you're looking for it can take the following values

auto | baseline | before-edge | text-before-edge | 
middle | central | after-edge | text-after-edge | 
ideographic | alphabetic | hanging | mathematical | 
inherit

Description from w3c

This property specifies how an object is aligned with respect to its parent. This property specifies which baseline of this element is to be aligned with the corresponding baseline of the parent. For example, this allows alphabetic baselines in Roman text to stay aligned across font size changes. It defaults to the baseline with the same name as the computed value of the alignment-baseline property. That is, the position of "ideographic" alignment-point in the block-progression-direction is the position of the "ideographic" baseline in the baseline-table of the object being aligned.

W3C Source

Unfortunately, although this is the "correct" way of achieving what you're after it would appear Firefox have not implemented a lot of the presentation attributes for the SVG Text Module ('SVG in Firefox' MDN Documentation)

When the propagation setting is PROPAGATION_REQUIRED, a logical transaction scope is created for each method upon which the setting is applied. Each such logical transaction scope can determine rollback-only status individually, with an outer transaction scope being logically independent from the inner transaction scope. Of course, in case of standard PROPAGATION_REQUIRED behavior, all these scopes will be mapped to the same physical transaction. So a rollback-only marker set in the inner transaction scope does affect the outer transaction's chance to actually commit (as you would expect it to).

You can also use Boost.Assignment:

Original Answer:

If you are ready to opt for CSS3, you can use css3 translate property. Resize based on whatever is bigger. If your height is bigger and width is smaller than container, width will be stretch to 100% and height will be trimmed from both side. Same goes for larger width as well.

Your need, HTML:

<div class="img-wrap">
  <img src="http://lorempixel.com/300/160/nature/" />
</div>
<div class="img-wrap">
  <img src="http://lorempixel.com/300/200/nature/" />
</div>
<div class="img-wrap">
  <img src="http://lorempixel.com/200/300/nature/" />
</div>

And CSS:

.img-wrap {
  width: 200px;
  height: 150px;
  position: relative;
  display: inline-block;
  overflow: hidden;
  margin: 0;
}

div > img {
  display: block;
  position: absolute;
  top: 50%;
  left: 50%;
  min-height: 100%;
  min-width: 100%;
  transform: translate(-50%, -50%);
}

Voila! Working: http://jsfiddle.net/shekhardesigner/aYrhG/

Explanation

DIV is set to the relative position. This means all the child elements will get the starting coordinates (origins) from where this DIV starts.

The image is set as a BLOCK element, min-width/height both set to 100% means to resize the image no matter of its size to be the minimum of 100% of it's parent. min is the key. If by min-height, the image height exceeded the parent's height, no problem. It will look for if min-width and try to set the minimum height to be 100% of parents. Both goes vice-versa. This ensures there are no gaps around the div but image is always bit bigger and gets trimmed by overflow:hidden;

Now image, this is set to an absolute position with left:50% and top:50%. Means push the image 50% from the top and left making sure the origin is taken from DIV. Left/Top units are measured from the parent.

Magic moment:

transform: translate(-50%, -50%);

Now, this translate function of CSS3 transform property moves/repositions an element in question. This property deals with the applied element hence the values (x, y) OR (-50%, -50%) means to move the image negative left by 50% of image size and move to the negative top by 50% of image size.

Eg. if Image size was 200px × 150px, transform:translate(-50%, -50%) will calculated to translate(-100px, -75px). % unit helps when we have various size of image.

This is just a tricky way to figure out centroid of the image and the parent DIV and match them.

Apologies for taking too long to explain!

You cannot get the exact code, but you can get a decompiled version of it.

The most popular (and best) tool is Reflector, but there are also other .Net decompilers (such as Dis#). You can also decompile the IL using ILDASM, which comes bundled with the .Net Framework SDK Tools.

The best solution would be to use the so-called Element Queries. However, they are not standard, no specification exists - and the only option is to use one of the polyfills/libraries available, if you want to go this way.

The idea behind element queries is to allow a certain container on the page to respond to the space that's provided to it. This will allow to write a component once and then drop it anywhere on the page, while it will adjust its contents to its current size. No matter what the Window size is. This is the first difference that we see between element queries and media queries. Everyone hopes that at some point a specification will be created that will standardize element queries (or something that achieves the same goal) and make them native, clean, simple and robust. Most people agree that Media queries are quite limited and don't help for modular design and true responsiveness.

There are a few polyfills/libraries that solve the problem in different ways (could be called workarounds instead of solutions though):

• CSS Element Queries - https://github.com/marcj/css-element-queries
• BoomQueries - https://github.com/BoomTownROI/boomqueries
• eq.js - https://github.com/Snugug/eq.js
• ElementQuery - https://github.com/tysonmatanich/elementQuery
• And a few more, which I'm not going to list here, but you're free to search. I would not be able to say which of the currently available options is the best. You'll have to try a few and decide.

I have seen other solutions to similar problems proposed. Usually they use timers or the Window/viewport size under the hood, which is not a real solution. Furthermore, I think ideally this should be solved mainly in CSS, and not in javascript or html.

The easiest way is to turn the int into a string and take each character of the string as an element of your list:

>>> n = 43365644 
>>> digits = [int(x) for x in str(n)]
>>> digits
[4, 3, 3, 6, 5, 6, 4, 4]
>>> lst.extend(digits)  # use the extends method if you want to add the list to another

It involves a casting operation, but it's readable and acceptable if you don't need extreme performance.

Hi this issue is because docker containers exit if there is no running application in the container.

-d 

option is just to run a container in deamon mode.

So the trick to make your container continuously running is point to a shell file in docker which will keep your application running.You can try with a start.sh file

Eg: docker run -d centos sh /yourlocation/start.sh

This start.sh should point to a never ending application.

In case if you dont want any application to be running,you can install monit which will keep your docker container running. Please let us know if these two cases worked for you to keep your container running.

All the best

Extending @nevermind's answer, one can use DateTime::createFromFormat: like,

// use - instead of _. replace _ by - if needed.
$format = "d-m-y";
$date1  = DateTime::createFromFormat($format, date('d-m-y'));
$date2  = DateTime::createFromFormat($format, str_replace("_", "-",$date2));    
var_dump($date1 > $date2);

You can always extend String prototype like this:

//  Checks that string starts with the specific string
if (typeof String.prototype.startsWith != 'function') {
    String.prototype.startsWith = function (str) {
        return this.slice(0, str.length) == str;
    };
}

//  Checks that string ends with the specific string...
if (typeof String.prototype.endsWith != 'function') {
    String.prototype.endsWith = function (str) {
        return this.slice(-str.length) == str;
    };
}

And use it like this:

var str = 'Hello World';

if( str.startsWith('Hello') ) {
   // your string starts with 'Hello'
}

if( str.endsWith('World') ) {
   // your string ends with 'World'
}

I ended up finding MinimalistTelnet and adapted it to my uses. I ended up needing to be able to heavily modify the code due to the unique** device that I am attempting to attach to.

** Unique in this instance can be validly interpreted as brain-dead.

I use Object.keys which is built into JavaScript Object, it will return an array of keys from given object MDN Reference

var obj = {name: "Jeeva", age: "22", gender: "Male"}
console.log(Object.keys(obj))

SELECT <...>
FROM A.table1 t1 JOIN B.table2 t2 ON t2.column2 = t1.column1;

Just make sure that in the SELECT line you specify which table columns you are using, either by full reference, or by alias. Any of the following will work:

SELECT *
SELECT t1.*,t2.column2
SELECT A.table1.column1, t2.*
etc.

Assuming you are connecting GitHub over SSH, you can run below command to confirm this.

$git config --get remote.origin.url

If you get a result has following format [email protected]:xxx/xxx.github.com.git, then you should do the following.

Generate a SSH key(or use existing one). if you had one, you just need to add your key to the ssh-agent (step 2)and to your GitHub account(step 3).

below are for those who don't have SSH key.

Step 1 Generating public/private rsa key pair.

$ssh-keygen -t rsa -b 4096 -C "[email protected]"

You'll be asked to confirm where to save the SSH key and what passphrase you want to use.

Step 2 Add your key to the ssh-agent

• Ensure ssh-agent is enabled

  $eval "$(ssh-agent -s)"

• Add your SSH key to the ssh-agent:

  $ssh-add ~/.ssh/id_rsa

Step 3 Add your SSH key to your account

$sudo apt-get install xclip

$xclip -sel clip < ~/.ssh/id_rsa.pub

Then add the copied key to GitHub

Go to Settings->SSH keys(Personal settings side bar)->Add SSH key->fill out form(key is on your clipboard, just use ctrl+v)->Add key

After going through above steps, you should solve the permission problem.

Bootstrap 3

Here is a working left sidebar example:

http://bootply.com/90936 (similar to the Bootstrap docs)

The trick is using the affix component along with some CSS to position it:

  #sidebar.affix-top {
    position: static;
    margin-top:30px;
    width:228px;
  }

  #sidebar.affix {
    position: fixed;
    top:70px;
    width:228px;
  }

EDIT- Another example with footer and affix-bottom

Bootstrap 4

The Affix component has been removed in Bootstrap 4, so to create a sticky sidebar, you can use a 3rd party Affix plugin like this Bootstrap 4 sticky sidebar example, or use the sticky-top class is explained in this answer.

The python code you write is compiled into python bytecode, which creates file with extension .pyc. If compiles, again question is, why not compiled language.

Note that this isn't compilation in the traditional sense of the word. Typically, we’d say that compilation is taking a high-level language and converting it to machine code. But it is a compilation of sorts. Compiled in to intermediate code not into machine code (Hope you got it Now).

Back to the execution process, your bytecode, present in pyc file, created in compilation step, is then executed by appropriate virtual machines, in our case, the CPython VM The time-stamp (called as magic number) is used to validate whether .py file is changed or not, depending on that new pyc file is created. If pyc is of current code then it simply skips compilation step.

from sklearn import metrics              
import numpy as np
print(np.sqrt(metrics.mean_squared_error(y_test,y_predict)))

You can achieve this using the location object.

location.href = "http://someurl"; 

CURLOPT_POSTFIELDS as the name suggests, is for the body (payload) of a POST request. For GET requests, the payload is part of the URL in the form of a query string.

In your case, you need to construct the URL with the arguments you need to send (if any), and remove the other options to cURL.

curl_setopt($ch, CURLOPT_URL, $this->service_url.'user/'.$id_user);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_HEADER, 0);

//$body = '{}';
//curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "GET"); 
//curl_setopt($ch, CURLOPT_POSTFIELDS,$body);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

According with the HTTP/1.1 standard, the shared IP hosted site can be accessed by a GET request with the IP as URL and a header of the host.

Here there are two examples(wget and curl): $ wget --header 'Host:somerandomservice.com' http://67.225.235.59 $ curl --header 'Host:somerandomservice.com' http://67.225.235.59

You can add multiple aar dependencies with just few lines of code.

Add local flatDir repository:

repositories {
    flatDir {
        dirs 'libs'
    }
} 

Add every aar in libs directory to compile dependency configuration:

fileTree(dir: 'libs', include: '**/*.aar')
        .each { File file ->
    dependencies.add("compile", [name: file.name.lastIndexOf('.').with { it != -1 ? file.name[0..<it] : file.name }, ext: 'aar'])
}

Even better, use DEFAULT instead of NULL. You want to store the default value, not a NULL that might trigger a default value.

But you'd better name all columns, with a piece of SQL you can create all the INSERT, UPDATE and DELETE's you need. Just check the information_schema and construct the queries you need. There is no need to do it all by hand, SQL can help you out.

/**
 * <blockquote><pre>
 * {@code
 * public Foo(final Class<?> klass) {
 *     super();
 *     this.klass = klass;
 * }
 * }
 * </pre></blockquote>
 **/

• <pre/> is required for preserving lines.
• {@code must has its own line
• <blockquote/> is just for indentation.

public Foo(final Class<?> klass) {
    super();
    this.klass = klass;
}

The minimum requirements for proper codes are <pre/> and {@code}.

/**
 * test.
 *
 * <pre>{@code
 * <T> void test(Class<? super T> type) {
 *     System.out.printf("hello, world\n");
 * }
 * }</pre>
 */

yields

 <T> void test(Class<? super T> type) {
     System.out.printf("hello, world\n");
 }

And an optional surrounding <blockquote/> inserts an indentation.

/**
 * test.
 *
 * <blockquote><pre>{@code
 * <T> void test(Class<? super T> type) {
 *     System.out.printf("hello, world\n");
 * }
 * }</pre></blockquote>
 */

yields

     <T> void test(Class<? super T> type) {
         System.out.printf("hello, world\n");
     }

Inserting <p> or surrounding with <p> and </p> yields warnings.

getSupportActionBar().setDisplayShowTitleEnabled(false);

I ran into this having 2 Doctrine DBAL connections, one of those as non-transactional (for important logs), they are intended to run parallel not depending on each other.

CodeExecution(
    TransactionConnectionQuery()
    TransactionlessConnectionQuery()
)

My integration tests were wrapped into transactions for data rollback after very test.

beginTransaction()
CodeExecution(
    TransactionConnectionQuery()
    TransactionlessConnectionQuery() // CONFLICT
)
rollBack()

My solution was to disable the wrapping transaction in those tests and reset the db data in another way.

I am receiving the data from a web-service that sends NaN as a string 'Nan'. But there could be other sorts of string in my data as well, so a simple float(value) could throw an exception. I used the following variant of the accepted answer:

def isnan(value):
  try:
      import math
      return math.isnan(float(value))
  except:
      return False

Requirement:

isnan('hello') == False
isnan('NaN') == True
isnan(100) == False
isnan(float('nan')) = True

This is how I clear the data:

Sub Macro3()
    With Sheet1.ListObjects("Table1")
        If Not .DataBodyRange Is Nothing Then
            .DataBodyRange.Delete
        End If
    End With
End Sub

Here is a method I used and worked for me

    String sql="";
    Object[] parameters = null;
    try{
        CriteriaImpl c = (CriteriaImpl) criteria;
        SessionImpl s = (SessionImpl)c.getSession();
        SessionFactoryImplementor factory = (SessionFactoryImplementor)s.getSessionFactory();
        String[] implementors = factory.getImplementors( c.getEntityOrClassName() );
        CriteriaLoader loader = new CriteriaLoader((OuterJoinLoadable)factory.getEntityPersister(implementors[0]), factory, c, implementors[0], s.getEnabledFilters());
        Field f = OuterJoinLoader.class.getDeclaredField("sql");
        f.setAccessible(true);
        sql = (String)f.get(loader);
        Field fp = CriteriaLoader.class.getDeclaredField("traslator");
        fp.setAccessible(true);
        CriteriaQueryTranslator translator = (CriteriaQueryTranslator) fp.get(loader);
        parameters = translator.getQueryParameters().getPositionalParameterValues();
    }
    catch(Exception e){
        throw new RuntimeException(e);
    }
    if (sql !=null){
        int fromPosition = sql.indexOf(" from ");
        sql = "SELECT * "+ sql.substring(fromPosition);

        if (parameters!=null && parameters.length>0){
            for (Object val : parameters) {
                String value="%";
                if(val instanceof Boolean){
                    value = ((Boolean)val)?"1":"0";
                }else if (val instanceof String){
                    value = "'"+val+"'";
                }
                sql = sql.replaceFirst("\\?", value);
            }
        }
    }
    return sql.replaceAll("left outer join", "\nleft outer join").replace(" and ", "\nand ").replace(" on ", "\non ");
}

The problem is that if you try to write a <table> or a <tr> or <td> tag using JS every time you insert a new tag the browser will try to close it as it will think that there is an error on the code.

Instead of writing your table line by line, concatenate your table into a variable and insert it once created:

<script language="javascript" type="text/javascript">
<!--

var myArray    = new Array();
    myArray[0] = 1;
    myArray[1] = 2.218;
    myArray[2] = 33;
    myArray[3] = 114.94;
    myArray[4] = 5;
    myArray[5] = 33;
    myArray[6] = 114.980;
    myArray[7] = 5;

    var myTable= "<table><tr><td style='width: 100px; color: red;'>Col Head 1</td>";
    myTable+= "<td style='width: 100px; color: red; text-align: right;'>Col Head 2</td>";
    myTable+="<td style='width: 100px; color: red; text-align: right;'>Col Head 3</td></tr>";

    myTable+="<tr><td style='width: 100px;                   '>---------------</td>";
    myTable+="<td     style='width: 100px; text-align: right;'>---------------</td>";
    myTable+="<td     style='width: 100px; text-align: right;'>---------------</td></tr>";

  for (var i=0; i<8; i++) {
    myTable+="<tr><td style='width: 100px;'>Number " + i + " is:</td>";
    myArray[i] = myArray[i].toFixed(3);
    myTable+="<td style='width: 100px; text-align: right;'>" + myArray[i] + "</td>";
    myTable+="<td style='width: 100px; text-align: right;'>" + myArray[i] + "</td></tr>";
  }  
   myTable+="</table>";

 document.write( myTable);

//-->
</script> 

If your code is in an external JS file, in HTML create an element with an ID where you want your table to appear:

<div id="tablePrint"> </div>

And in JS instead of document.write(myTable) use the following code:

document.getElementById('tablePrint').innerHTML = myTable;

You should all know this is inline scripting and is not a good practice at all...with that said you should definitively use javascript or jQuery for this type of thing:

HTML

<!DOCTYPE html> 
<html> 
 <head> 
    <meta charset="ISO-8859-1"> 
    <title>Online Student Portal</title> 
 </head> 
 <body> 
    <form action="">
         <input type="button" id="myButton" value="Add"/>
    </form> 
 </body> 
</html>

JQuery

var button_my_button = "#myButton";
$(button_my_button).click(function(){
 window.location.href='Students.html';
});

Javascript

  //get a reference to the element
  var myBtn = document.getElementById('myButton');

  //add event listener
  myBtn.addEventListener('click', function(event) {
    window.location.href='Students.html';
  });

See comments why avoid inline scripting and also why inline scripting is bad

Check out array_merge().

$array3 = array_merge($array1, $array2);

You can use the git show command.

To get the last commit date from git repository in a long(Unix epoch timestamp):

• Command: git show -s --format=%ct
• Result: 1605103148

Note: You can visit the git-show documentation to get a more detailed description of the options.

You can do it very easily with a Cloud Management software -like enStratus, RightScale or Scalr (disclaimer: I work there). With the cloned farm you can:

1. Create a snapshot or a pre-made image to launch another day
2. Duplicate your configuration to test it before production

This is the code I usually do:

 try
 {
    ...........
    throw null;//this line just works like a 'break'
    ...........   
  }
  catch (NullReferenceException)
  { 
  }
  catch (System.Exception ex)
  {
      .........
  }

git Stash list 

List will show all stashed items eg:stash@{0}:,stash@{1}:,..,stash@{n}:

Then select the number n which denotes stash@{n}:

git stash apply n 

for example:

git stash apply 1 

will apply that particular stashed changes to the current branch

Yep it is here, using _.reduce

var params = [
    { name: 'foo', input: 'bar' },
    { name: 'baz', input: 'zle' }
];

_.reduce(params , function(obj,param) {
 obj[param.name] = param.input
 return obj;
}, {});

Try something like this:

try {
    $w = New-Object net.WebClient
    $d = $w.downloadString('http://foo')
}
catch [Net.WebException] {
    Write-Host $_.Exception.ToString()
}

The exception is in the $_ variable. You might explore $_ like this:

try {
    $w = New-Object net.WebClient
    $d = $w.downloadString('http://foo')
}
catch [Net.WebException] {
    $_ | fl * -Force
}

I think it will give you all the info you need.

My rule: if there is some data that is not displayed, try to use -force.

to make it work in IE-9 use below .it works for me

JQuery need to include:

jQuery(function() {
   jQuery.support.placeholder = false;
   webkit_type = document.createElement('input');
   if('placeholder' in webkit_type) jQuery.support.placeholder = true;});
   $(function() {

     if(!$.support.placeholder) {

       var active = document.activeElement;

       $(':text, textarea, :password').focus(function () {

       if (($(this).attr('placeholder')) && ($(this).attr('placeholder').length > 0) &&         ($(this).attr('placeholder') != '') && $(this).val() == $(this).attr('placeholder')) {
          $(this).val('').removeClass('hasPlaceholder');
        }
      }).blur(function () {
if (($(this).attr('placeholder')) && ($(this).attr('placeholder').length > 0) &&  ($(this).attr('placeholder') != '') && ($(this).val() == '' || $(this).val() ==   $(this).attr('placeholder'))) {
     $(this).val($(this).attr('placeholder')).addClass('hasPlaceholder');
}
});

$(':text, textarea, :password').blur();
$(active).focus();
$('form').submit(function () {
     $(this).find('.hasPlaceholder').each(function() { $(this).val(''); });
});
}
});

CSS Style need to include:

.hasPlaceholder {color: #aaa;}

You can use

#pragma GCC push_options
#pragma GCC optimize ("O0")

your code

#pragma GCC pop_options

to disable optimizations since GCC 4.4.

See the GCC documentation if you need more details.

You need to install msysgit, after installing you need to open Git Bash and enter there these commands:

$ git config --global user.name "Gennadiy Zlobin" (your name)
$ git config --global user.email [email protected] (your email)
$ ssh-keygen -C "[email protected]" -t rsa (your email)

Now your generated keys are in C:\Users\username\.ssh (in Windows 7).
Next you load the content of your public key to your project on Github
In Eclipse open Window->Preferences->General->Network->SSH2 and set your ~/.ssh as SSH Home

After that go to Key Management tab and Load existing Key - set here your private key in ~/.ssh.

After that you can push your project to Github (but I set ssh protocol, not git+ssh).

The typical command is:

docker container ls -f 'status=exited'

However, this will only list one of the possible non-running statuses. Here's a list of all possible statuses:

• created
• restarting
• running
• removing
• paused
• exited
• dead

You can filter on multiple statuses by passing multiple filters on the status:

docker container ls -f 'status=exited' -f 'status=dead' -f 'status=created'

If you are integrating this with an automatic cleanup script, you can chain one command to another with some bash syntax, output just the container id's with -q, and you can also limit to just the containers that exited successfully with an exit code filter:

docker container rm $(docker container ls -q -f 'status=exited' -f 'exited=0')

For more details on filters you can use, see Docker's documentation: https://docs.docker.com/engine/reference/commandline/ps/#filtering

Another way of doing it is take the current date convert it into long just take the last 4 digits. There is a high probability that the number will be unique.

    long time = new Date().getTime();
    String tmpStr = String.valueOf(time);
    String last4Str = tmpStr.substring(tmpStr.length() -5);
    int notificationId = Integer.valueOf(last4Str);

Files.exists()

Files.createDirectory()

Files.copy()

Overwriting Existing Files: Files.move()

Files.delete()

Files.walkFileTree() enter link description here

Indeed, something could be done under specific occasion: for example if you want to check whether a string pointer string is valid, using write(fd, buf, szie) syscall can help you do the magic: let fd be a file descriptor of temporary file you create for test, and buf pointing to the string you are tesing, if the pointer is invalid write() would return -1 and errno set to EFAULT which indicating that buf is outside your accessible address space.

An analytic solution with only one nested query:

SELECT * FROM
(
   SELECT t.*, Row_Number() OVER (ORDER BY name) MyRow FROM sometable t
) 
WHERE MyRow BETWEEN 10 AND 20;

Rank() could be substituted for Row_Number() but might return more records than you are expecting if there are duplicate values for name.

In .net core 3.1 (and other more recent versions), you can use:

private readonly UserManager<IdentityUser> _userManager;

public ExampleController(UserManager<IdentityUser> userManager)
{
    _userManager = userManager;
}

Then:

string userId = _userManager.GetUserId(User);

Or async:

var user = await _userManager.GetUserAsync(User);
var userId = user.Id;

At this point, I'm trying to figure out why you'd use one over the other. I know the general benefits of async, but see both of these used frequently. Please post some comments if anyone knows.

The way we have done it was using Broadcasts:

1. Send the broadcast every time the user changes language
2. Register the broadcast receiver in the AppActivity.onCreate() and unregister in AppActivity.onDestroy()
3. In BroadcastReceiver.onReceive() just restart the activity.

AppActivity is the parent activity which all other activities subclass.

Below is the snippet from my code, not tested outside the project, but should give you a nice idea.

When the user changes the language

sendBroadcast(new Intent("Language.changed"));

And in the parent activity

public class AppActivity extends Activity {

    /**
     * The receiver that will handle the change of the language.
     */
    private BroadcastReceiver mLangaugeChangedReceiver;

    @Override
    protected void onCreate(final Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // ...
        // Other code here
        // ...

        // Define receiver
        mLangaugeChangedReceiver = new BroadcastReceiver() {

            @Override
            public void onReceive(final Context context, final Intent intent) {
                startActivity(getIntent());
                finish();
            }
        };

        // Register receiver
        registerReceiver(mLangaugeChangedReceiver, new IntentFilter("Language.changed"));
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();

        // ...
        // Other cleanup code here
        // ...

        // Unregister receiver
        if (mLangaugeChangedReceiver != null) {
            try {
                unregisterReceiver(mLangaugeChangedReceiver);
                mLangaugeChangedReceiver = null;
            } catch (final Exception e) {}
        }
    }
}

This will also refresh the activity which changed the language (if it subclasses the above activity).

This will make you lose any data, but if it is important you should already have taken care of this using Actvity.onSaveInstanceState() and Actvity.onRestoreInstanceState() (or similar).

Let me know your thoughts about this.

Cheers!

1. Like you installed older version of PHP do the same with Apache. I picked version 2.0.63 and then I was able to run WAMP Server with PHP 5.2.9 with no problems.

2. I also read that it's problem with 64-bit version of WAMP.

I think this topic is totally overdiscussed/overcomplicated. Using an IDE is THE way to go to completely avoid any syntax errors. I would even say that working without an IDE is kind of unprofessional. Why? Because modern IDEs check your syntax after every character you type. When you code and your entire line turns red, and a big warning notice shows you the exact type and the exact position of the syntax error, then there's absolutely no need to search for another solution.

Using a syntax-checking IDE means:

You'll (effectively) never run into syntax errors again, simply because you see them right as you type. Seriously.

Excellent IDEs with syntax check (all of them are available for Linux, Windows and Mac):

1. NetBeans [free]
2. PHPStorm [$199 USD]
3. Eclipse with PHP Plugin [free]
4. Sublime [$80 USD] (mainly a text editor, but expandable with plugins, like PHP Syntax Parser)

Further to this, the return type is determined by

1. What the HTTP Request says it wants - in its Accept header. Try looking at the initial request as see what Accept is set to.

2. What HttpMessageConverters Spring sets up. Spring MVC will setup converters for XML (using JAXB) and JSON if Jackson libraries are on he classpath.

If there is a choice it picks one - in this example, it happens to be JSON.

This is covered in the course notes. Look for the notes on Message Convertors and Content Negotiation.

none of all above answers working good on my app

here is my working code

on your exit button:

Intent intent = new Intent(getApplicationContext(), MainActivity.class);
ComponentName cn = intent.getComponent();
Intent mainIntent = IntentCompat.makeRestartActivityTask(cn);
mainIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
mainIntent.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
mainIntent.putExtra("close", true);
startActivity(mainIntent);
finish();

that code is to close any other activity and bring MainActivity on top now on your MainActivity:

if( getIntent().getBooleanExtra("close", false)){
    finish();
}

Not possible to load static local files(eg:svg) without server. If you have NPM /YARN installed in your machine, you can setup simple http server using "http-server"

npm install http-server -g
http-server [path] [options]

Or open terminal in that project folder and type "hs". It will automaticaly start HTTP live server.

Use an extension method instead:

public static class ExtensionMethods
{
    public static int IntValue(this Enum argEnum)
    {
        return Convert.ToInt32(argEnum);
    }
}

And the usage is slightly prettier:

var intValue = Question.Role.IntValue();

One of the way I do it is by creating a 'Global' class with the constant values and do a static import in the classes that need access to the constant.

you can use just javascript for it

var total =10.8
(total).toFixed(2); 10.80


alert(total.toFixed(2))); 

To use $this->input->post() initialize the form helper. You could do that by default in config.

Try this:

select * 
from xxx 
where dates >= '2012-10-26 00:00:00.000' and dates <= '2012-10-27 23:59:59.997'

If you are using a declarative syntax of Jenkinsfile to describe your building pipeline, you can use changeset condition to limit stage execution only to the case when specific files are changed. This is now a standard feature of Jenkins and does not require any additional configruation/software.

stages {
    stage('Nginx') {
        when { changeset "nginx/*"}
        steps {
            sh "make build-nginx"
            sh "make start-nginx"
        }
    }
}

You can combine multiple conditions using anyOf or allOf keywords for OR or AND behaviour accordingly:

when {
    anyOf {
        changeset "nginx/**"
        changeset "fluent-bit/**"
    }
}
steps {
    sh "make build-nginx"
    sh "make start-nginx"
}

Make sure you die() after your redirection, and make sure you do your redirect AS SOON AS POSSIBLE while your script executes. It makes sure that no more database queries (if some) are not wasted for nothing. That's the one tip I can give you

For search engines, 301 is the best response code

That query is failing and returning false.

Put this after mysqli_query() to see what's going on.

if (!$check1_res) {
    printf("Error: %s\n", mysqli_error($con));
    exit();
}

There are lot of different Timers in the .NET BCL:

• System.Timers.Timer
• System.Threading.Timer
• System.Windows.Forms.Timer
• System.Web.UI.Timer
• System.Windows.Threading.DispatcherTimer

When to use which?

• System.Timers.Timer, which fires an event and executes the code in one or more event sinks at regular intervals. The class is intended for use as a server-based or service component in a multithreaded environment; it has no user interface and is not visible at runtime.
• System.Threading.Timer, which executes a single callback method on a thread pool thread at regular intervals. The callback method is defined when the timer is instantiated and cannot be changed. Like the System.Timers.Timer class, this class is intended for use as a server-based or service component in a multithreaded environment; it has no user interface and is not visible at runtime.
• System.Windows.Forms.Timer (.NET Framework only), a Windows Forms component that fires an event and executes the code in one or more event sinks at regular intervals. The component has no user interface and is designed for use in a single-threaded environment; it executes on the UI thread.
• System.Web.UI.Timer (.NET Framework only), an ASP.NET component that performs asynchronous or synchronous web page postbacks at a regular interval.
• System.Windows.Threading.DispatcherTimer, a timer that's integrated into the Dispatcher queue. This timer is processed with a specified priority at a specified time interval.

Source

Some of them needs explicit Start call to begin ticking (for example System.Timers, System.Windows.Forms). And an explicit Stop to finish ticking.

using TimersTimer = System.Timers.Timer;

static void Main(string[] args)
{
    var timer = new TimersTimer(1000);
    timer.Elapsed += (s, e) => Console.WriteLine("Beep");
    Thread.Sleep(1000); //1 second delay
    timer.Start();
    Console.ReadLine();
    timer.Stop();

}

While on the other hand there are some Timers (like: System.Threading) where you don't need explicit Start and Stop calls. (The provided delegate will run a background thread.) Your timer will tick until you or the runtime dispose it.

So, the following two versions will work in the same way:

using ThreadingTimer = System.Threading.Timer;

static void Main(string[] args)
{
    var timer = new ThreadingTimer(_ => Console.WriteLine("Beep"), null, TimeSpan.FromSeconds(1), TimeSpan.FromSeconds(1));
    Console.ReadLine();
}

using ThreadingTimer = System.Threading.Timer;
static void Main(string[] args)
{
    StartTimer();
    Console.ReadLine();
}

static void StartTimer()
{
    var timer = new ThreadingTimer(_ => Console.WriteLine("Beep"), null, TimeSpan.FromSeconds(1), TimeSpan.FromSeconds(1));
}

But if your timer disposed then it will stop ticking obviously.

using ThreadingTimer = System.Threading.Timer; 

static void Main(string[] args)
{
    StartTimer();
    GC.Collect(0);
    Console.ReadLine();
}

static void StartTimer()
{
    var timer = new ThreadingTimer(_ => Console.WriteLine("Beep"), null, TimeSpan.FromSeconds(1), TimeSpan.FromSeconds(1));
}

You can use the linux bash core utility split

split -b 1M -d  file.txt file 

Note that M or MB both are OK but size is different. MB is 1000 * 1000, M is 1024^2

If you want to separate by lines you can use -l parameter.

UPDATE

a=(`wc -l yourfile`) ; lines=`echo $(($a/12)) | bc -l` ; split -l $lines -d  file.txt file

Another solution as suggested by Kirill, you can do something like the following

split -n l/12 file.txt

Note that is l not one, split -n has a few options, like N, k/N, l/k/N, r/N, r/k/N.

Try This

;With Tab AS (SELECT DISTINCT Email FROM  Products)
SELECT Email,ROW_NUMBER() OVER(ORDER BY Email ASC) AS  Id FROM Tab
ORDER BY Email ASC

If you want a simple solution just to create and verify serial numbers, try Ellipter. It uses elliptic curves cryptography and has an "Expiration Date" feature so you can create trial verisons or time-limited registration keys.

While the other answers are correct (int array values are by default initialized to 0), if you wanted to explicitly do so (say for example if you wanted an array filled with the value 42), you can use the fill() method of the Arrays class:

int [] myarray = new int[num_elts];
Arrays.fill(myarray, 42);

Or if you're a fan of 1-liners, you can use the Collections.nCopies() routine:

Integer[] arr = Collections.nCopies(3, 42).toArray(new Integer[0]);

Would give arr the value:

[42, 42, 42]

(though it's Integer, and not int, if you need the primitive type you could defer to the Apache Commons ArrayUtils.toPrimitive() routine:

int [] primarr = ArrayUtils.toPrimitive(arr);

Just for anyone who still has an issue, I also had an issue where I typed ngif rather than ngIf (notice the capital 'I').

If you are having 112 columns in one single table and you would like to insert data from source table, you could do as

create table employees as select * from source_employees where employee_id=100;

Or from sqlplus do as

copy from source_schema/password insert employees using select * from 
source_employees where employee_id=100;

In SQL Management Studio you can:

1. Right click on the result set grid, select 'Save Result As...' and save in.

2. On a tool bar toggle 'Result to Text' button. This will prompt for file name on each query run.

If you need to automate it, use bcp tool.

It is possible to pass arrays to functions, and there are no special requirements for dealing with them. Are you sure that the array you are passing to to your function actually has an element at [0]?

    object_id,

It seems that you are trying to get 5 items out of a collection with 5 items. Looking at your code, it seems you're starting at the second value in your collection at position 1. Collections are zero-based, so you should start with the item at index 0. Try this:

TextBox box1 = (TextBox)Gridview1.Rows[i].Cells[0].FindControl("txt_type");
TextBox box2 = (TextBox)Gridview1.Rows[i].Cells[1].FindControl("txt_total");
TextBox box3 = (TextBox)Gridview1.Rows[i].Cells[2].FindControl("txt_max");
TextBox box4 = (TextBox)Gridview1.Rows[i].Cells[3].FindControl("txt_min");
TextBox box5 = (TextBox)Gridview1.Rows[i].Cells[4].FindControl("txt_rate");

You can use bit mask (1<< k) and do AND operation with number! 1 << k has one bit at k position!

private void printBits(int x) {
    for(int i = 31; i >= 0; i--) {
        if((x & (1 << i)) != 0){
            System.out.print(1);
        }else {
            System.out.print(0);
        }
    }
    System.out.println();
}

This will refresh current fragment :

FragmentTransaction ft = getFragmentManager().beginTransaction();
if (Build.VERSION.SDK_INT >= 26) {
   ft.setReorderingAllowed(false);
}
ft.detach(this).attach(this).commit();

While the methods above might work, here is a very good method.

Extend the core controller with a MY controller, then extend this MY controller for all your other controllers. For example, you could have:

class MY_Controller extends CI_Controller {
    public function is_logged()
    {
        //Your code here
    }
public function logout()
    {
        //Your code here
    }
}

Then your other controllers could then extend this as follows:

class Another_Controller extends MY_Controller {
    public function show_home()
    {
         if (!$this->is_logged()) {
           return false;
         }
    }
public function logout()
    {
        $this->logout();
    }
}

EDIT: Per Michael Dillon's answer, SaveAsText does save the commands in a macro without having to go through converting to VBA. I don't know what happened when I tested that, but it didn't produce useful text in the resulting file.

So, I learned something new today!

ORIGINAL POST: To expand the question, I wondered if there was a way to retrieve the contents of a macro from code, and it doesn't appear that there is (at least not in A2003, which is what I'm running).

There are two collections through which you can access stored Macros:

  CurrentDB.Containers("Scripts").Documents
  CurrentProject.AllMacros

The properties that Intellisense identifies for the two collections are rather different, because the collections are of different types. The first (i.e., traditional, pre-A2000 way) is via a documents collection, and the methods/properties/members of all documents are the same, i.e., not specific to Macros.

Likewise, the All... collections of CurrentProject return collections where the individual items are of type Access Object. The result is that Intellisense gives you methods/properties/members that may not exist for the particular document/object.

So far as I can tell, there is no way to programatically retrieve the contents of a macro.

This would stand to reason, as macros aren't of much use to anyone who would have the capability of writing code to examine them programatically.

But if you just want to evaluate what the macros do, one alternative would be to convert them to VBA, which can be done programmatically thus:

  Dim varItem As Variant
  Dim strMacroName As String

  For Each varItem In CurrentProject.AllMacros
    strMacroName = varItem.Name
    'Debug.Print strMacroName
    DoCmd.SelectObject acMacro, strMacroName, True
    DoCmd.RunCommand acCmdConvertMacrosToVisualBasic
    Application.SaveAsText acModule, "Converted Macro- " & strMacroName, _
      CurrentProject.Path & "\" & "Converted Macro- " & strMacroName & ".txt"
  Next varItem

Then you could use the resulting text files for whatever you needed to do.

Note that this has to be run interactively in Access because it uses DoCmd.RunCommand, and you have to click OK for each macro -- tedious for databases with lots of macros, but not too onerous for a normal app, which shouldn't have more than a handful of macros.

It's possible that your configuration variables are cached. Verify your config/app.php as well as your .env file then try

php artisan cache:clear

on the command line.

I had the same error.

My filename was jpaContext.xml and it was placed in src/main/resources. I specified param value="classpath:/jpaContext.xml".

Finally I renamed the file to applicationContext.xml and moved it to the WEB-INF directory and changed param value to /WEB-INF/applicationContext.xml, then it worked!

If you're using CloudFoundry then you'd have to explicitly push the jar along with the keystore having the certificate.

follow the python2.7 document, you have to use calendar.timegm() instead of time.mktime()

>>> d = datetime.date(2011,01,01)
>>> datetime.datetime.utcfromtimestamp(calendar.timegm(d.timetuple()))
datetime.datetime(2011, 1, 1, 0, 0)

Symfony HttpClient is asynchronous https://symfony.com/doc/current/components/http_client.html.

For example you can

use Symfony\Component\HttpClient\HttpClient;

$client = HttpClient::create();
$response1 = $client->request('GET', 'https://website1');
$response2 = $client->request('GET', 'https://website1');
$response3 = $client->request('GET', 'https://website1');
//these 3 calls with return immediately
//but the requests will fire to the website1 webserver

$response1->getContent(); //this will block until content is fetched
$response2->getContent(); //same 
$response3->getContent(); //same

Here's a variation of Shiv Kumar's answer, using Newtonsoft.Json (aka Json.NET):

public static bool SendAnSMSMessage(string message)
{
    var httpWebRequest = (HttpWebRequest)WebRequest.Create("http://api.pennysms.com/jsonrpc");
    httpWebRequest.ContentType = "text/json";
    httpWebRequest.Method = "POST";

    var serializer = new Newtonsoft.Json.JsonSerializer();
    using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
    {
        using (var tw = new Newtonsoft.Json.JsonTextWriter(streamWriter))
        {
             serializer.Serialize(tw, 
                 new {method= "send",
                      @params = new string[]{
                          "IPutAGuidHere", 
                          "[email protected]",
                          "MyTenDigitNumberWasHere",
                          message
                      }});
        }
    }
    var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
    using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
    {
        var responseText = streamReader.ReadToEnd();
        //Now you have your response.
        //or false depending on information in the response
        return true;        
    }
}

In java you can do some thing like:

if(driver.getTitle().contains("some expected text"))
    //Pass
    System.out.println("Page title contains \"some expected text\" ");
else
    //Fail
    System.out.println("Page title doesn't contains \"some expected text\" ");

Hers's what I used to get the day names (0-6 means monday - sunday):

public static String getFullDayName(int day) {
    Calendar c = Calendar.getInstance();
    // date doesn't matter - it has to be a Monday
    // I new that first August 2011 is one ;-)
    c.set(2011, 7, 1, 0, 0, 0);
    c.add(Calendar.DAY_OF_MONTH, day);
    return String.format("%tA", c);
}

public static String getShortDayName(int day) {
    Calendar c = Calendar.getInstance();
    c.set(2011, 7, 1, 0, 0, 0);
    c.add(Calendar.DAY_OF_MONTH, day);
    return String.format("%ta", c);
}

I got new way to resolve this issue. Here I have used google http service to get total information of location based on longitude and latitude. You just need to pass latitude and longitude in url and your api key (ex : latlng=21.1497409, 79.08747970000002 & key=YOUR API KEY). Here is my get service in ExampleServiceClass

 getService(url) {

    return this.http.get(url).map((data: any) => data.json())

}

this you can put anywhere you want and just call below service from component where you need location data

this._exampleService.getService("https://maps.googleapis.com/maps/api/geocode/json?latlng=21.1497409, 79.08747970000002&key=YOUR API KEY").subscribe(getplaceData => {
            var placeDataDest: any;
            placeDataDest = getplaceData;
            console.log("i got place id yeee " + placeDataDest['results'][0]['place_id']);
            console.log("i got place details yeee " + placeDataDest['results']);
        });

similarly find city name....hope you will find this useful

If you don't absolutely need to use a regex, useconsider using Perl's Text::Balanced to remove the parenthesis.

use Text::Balanced qw(extract_bracketed);

my ($extracted, $remainder, $prefix) = extract_bracketed( $filename, '()', '[^(]*' );

{   no warnings 'uninitialized';

    $filename = (defined $prefix or defined $remainder)
                ? $prefix . $remainder
                : $extracted;
}

You may be thinking, "Why do all this when a regex does the trick in one line?"

$filename =~ s/\([^}]*\)//;

Text::Balanced handles nested parenthesis. So $filename = 'foo_(bar(baz)buz)).foo' will be extracted properly. The regex based solutions offered here will fail on this string. The one will stop at the first closing paren, and the other will eat them all.

   $filename =~ s/\([^}]*\)//;
   # returns 'foo_buz)).foo'

   $filename =~ s/\(.*\)//;
   # returns 'foo_.foo'

   # text balanced example returns 'foo_).foo'

If either of the regex behaviors is acceptable, use a regex--but document the limitations and the assumptions being made.

This is how I would do it (the code below has been tested, full source provided below), begin by creating a class with common properties

    class Word
    {
        public string Base { get; set; }
        public string Category { get; set; }
        public string Id { get; set; }
    }

load using XDocument with INPUT_DATA for demonstration purposes and find element name with lexicon . . .

    XDocument doc = XDocument.Parse(INPUT_DATA);
    XElement lex = doc.Element("lexicon");

make sure there is a value and use linq to extract the word elements from it . . .

    Word[] catWords = null;
    if (lex != null)
    {
        IEnumerable<XElement> words = lex.Elements("word");
        catWords = (from itm in words
                    where itm.Element("category") != null
                        && itm.Element("category").Value == "verb"
                        && itm.Element("id") != null
                        && itm.Element("base") != null
                    select new Word() 
                    {
                        Base = itm.Element("base").Value,
                        Category = itm.Element("category").Value,
                        Id = itm.Element("id").Value,
                    }).ToArray<Word>();
    }

The where statement checks if the category element exists and that the category value is not null and then check it again that it is a verb. Then check that the other nodes also exists . . .

The linq query will return an IEnumerable< Typename > object, so we can call ToArray< Typename >() to cast the entire collection into the type we want.

Then print it to get . . .

Advanced Conventional Formatting [Update]

XMLSpectrum is an open source syntax-highlighter. Supporting XML - but with special features for XSLT 2.0, XSD 1.1 and XPath 2.0. I'm mentioning this here because it also has special formatting capabilities for XML: it vertically aligns attributes and their contents as well as elements - to enhance XML readability.

The output HTML is suitable for reviewing in a browser or if the XML needs further editing it can be copied and pasted into an XML editor of your choice

Because xmlspectrum.xsl uses its own XML text parser, all content such as entity references and CDATA sections are preserved - as in an editor.

Note on usage: this is just an XSLT 2.0 stylesheet so you would need to enclose the required command-line (samples provided) in a small script so you could automatically transform the XML source.

Virtual Formatting

XMLQuire is a free XML editor that has special formatting capabilities - it formats XML properly, including multi-line attributes, attribute-values, word-wrap indentation and even XML comments.

All XML indentation is done without inserting tabs or spaces, ensuring the integrity of the XML is maintained. For versions of Windows later than XP, no installation is needed, its just a 3MB .exe file.

If you need to print out the formatted XML there are special options within the print-preview, such as line-numbering that follows the indentation. If you need to copy the formatted XML to a word processor as rich text, that's available too.

[Disclosure: I maintain both XMLQuire and XMLSpectrum as 'home projects']

This code will convert the text 0xA7.0x9B.0x46.0x8D.0x1E.0x52.0xA7.0x9B.0x7B.0x31.0xD2 into a stream of 11 bytes with equivalent values. These bytes will be written to standard out.

TESTDATA=$(echo '0xA7.0x9B.0x46.0x8D.0x1E.0x52.0xA7.0x9B.0x7B.0x31.0xD2' | tr '.' ' ')
for c in $TESTDATA; do
    echo $c | xxd -r
done

As others have pointed out, this will not result in a printable ASCII string for the simple reason that the specified bytes are not ASCII. You need post more information about how you obtained this string for us to help you with that.

How it works: xxd -r translates hexadecimal data to binary (like a reverse hexdump). xxd requires that each line start off with the index number of the first character on the line (run hexdump on something and see how each line starts off with an index number). In our case we want that number to always be zero, since each execution only has one line. As luck would have it, our data already has zeros before every character as part of the 0x notation. The lower case x is ignored by xxd, so all we have to do is pipe each 0xhh character to xxd and let it do the work.

The tr translates periods to spaces so that for will split it up correctly.

In Android Studio, the options down the right corner of the IDE:

• Change/checkout other local branch
• Delete unwanted local branches (i.e. v0.0.1...)
• Delete unwanted remote branches (i.e. origin/v0.0.1...) -- this step will delete branches in BitBucket if the branches are not prevented to be deleted and they are not the MAIN BRANCH.

Above answers gave good solutions using Javscript. Here is a simple jQuery solution:

$('#iframeId').contents().find('div')

The trick here is jQuery's .contents() method, unlike .children() which can only get HTML elements, .contents() can get both text nodes and HTML elements. That's why one can get document contents of an iframe by using it.

Further reading about jQuery .contents(): .contents()

Note that the iframe and page have to be on the same domain.

I think the only ways to do this is outlined in this article.

The article explains several methods. Here is one example:

To do this in Microsoft Office Access 2007, follow these steps:

Delete the AutoNumber field from the main table.

1. Make note of the AutoNumber field name.
2. Click the Create tab, and then click Query Design in the Other group.
3. In the Show Table dialog box, select the main table. Click Add, and then click Close.
4. Double-click the required fields in the table view of the main table to select the fields.
5. Select the required Sort order.
6. On the Design tab, click Make Table in the Query Type group. Type the new table name in the Table Name box, and then click OK.
7. On the Design tab, click Run in the Results group.
8. The following message appears:

   You are about to paste # row(s) into a new table.

   Click Yes to insert the rows.
9. Close the query.
10. Right-click the new table, and then click Design View.
11. In the Design view for the table, add an AutoNumber field that has the same field name that you deleted in step 1. Add this AutoNumber field to the new table, and then save the table.
12. Close the Design view window.
13. Rename the main table name. Rename the new table name to the main table name.

You can also use /dev/urandom:

grep -m1 -ao '[0-9]' /dev/urandom | sed s/0/10/ | head -n1

• One reason BeanB may not exist in the context
• Another cause for the exception is the existence of two bean
• Or definitions in the context bean that isn’t defined is requested by name from the Spring context
