Questions : how to check File is empty or not?

Ans: I have slove this issue using this Jquery code

//If your file Is Empty :     _x000D_
      if (jQuery('#videoUploadFile').val() == '') {_x000D_
                       $('#message').html("Please Attach File");_x000D_
                   }else {_x000D_
                            alert('not work');_x000D_
                   }_x000D_
_x000D_
    

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<input type="file" id="videoUploadFile">_x000D_
<br>_x000D_
<br>_x000D_
<div id="message"></div>

Try PowerShell Type like:

$cn = new-object system.data.SqlClient.SQLConnection("Data Source=server1;Initial Catalog=db1;User ID=user1;Password=password1");
$cmd = new-object system.data.sqlclient.sqlcommand("exec Proc1", $cn);
$cn.Open();
$cmd.CommandTimeout = 0
$cmd.ExecuteNonQuery()
$cn.Close();

If you meet "Unknown SSL protocol error in connection to bitbucket.org:443" and you are in China, maybe github is been blocked by firewall temporarily. You can try to use VPN, which would work out. Good Luck!

jXPanel6.setVisible(jXPanel6.isVisible());

or in your form:

jXPanel6.setVisible(jXPanel6.isVisible()?true:false);

The following will return NULL if the array is empty, else the last element.

var item = (arr.Length == 0) ? null : arr[arr.Length - 1]

If the same error occurs in ADT/Eclipse

Add Action Bar Sherlock library in your project.

Now, to remove the "import The import android.support.v7 cannot be resolved" error download a jar file named as android-support-v7-appcompat.jar and add it in your project lib folder.

This will surely removes your both errors.

>>> a=[]
>>> a.append([1,2])
>>> a
[[1, 2]]
>>> a=[]
>>> a+=[1,2]
>>> a
[1, 2]

See that append adds a single element to the list, which may be anything. +=[] joins the lists.

You can loop the array with a for loop and the object properties with for-in loops.

for (var i=0; i<result.length; i++)
    for (var name in result[i]) {
        console.log("Item name: "+name);
        console.log("Source: "+result[i][name].sourceUuid);
        console.log("Target: "+result[i][name].targetUuid);
    }

int num = 1;
num.ToString("0000");

I came across an amazing resource on css-tricks: https://css-tricks.com/using-svg/

There are a handful of solutions explained there.

I preferred the one that required minimal edits to the source svg, and also didn't require it to be embedded into the html document. This option utilizes the <object> tag.

Add the svg file into your html using <object>; I also declared html attributes width and height. Using these width and heights the svg document does not get scaled, I worked around that using a css transform: scale(...) statement for the svg tag in my associated svg css file.

<object type="image/svg+xml" data="myfile.svg" width="64" height="64"></object>

Create a css file to attach to your svn document. My source svg path was scaled to 16px, I upscaled it to 64 with a factor of four. It only had one path so I did not need to select it more specifically, however the path had a fill attribute so I had to use !IMPORTANT to force the css to take precedent.

#svg2 {
    width: 64px; height: 64px;
    transform: scale(4);
}
path {
    fill: #333 !IMPORTANT;
}

Edit your target svg file, before the opening <svg tag, to include a stylesheet; Note that the href is relative to the svg file url.

<?xml-stylesheet type="text/css" href="myfile.css" ?>

On OS X, you need to take into account existing window decorations. They add 22 pixels to the height. So on a JFrame, you need to tell the program this:

frame.setSize(width, height + 22);

For those who just like me are newbies in JS and getting undefined instead of text value make sure that your id doesn't contain invalid characters.

If you set 'data' in your creation form, this value will be not modified when edit your entity.

My solution is :

public function buildForm(FormBuilderInterface $builder, array $options) {
    // In my example, data is an associated array
    $data = $builder->getData();

    $builder->add('myfield', 'text', array(
     'label' => 'Field',
     'data' => array_key_exits('myfield', $data) ? $data['myfield'] : 'Default value',
    ));
}

Bye.

As of October 2015, WP 4.3.1 I have found only two plugins actually affecting image locations as in “folders & subfolders”:

• Custom Upload Dir, but as the name says, just on upload. You can work from your %post_slug% or %categories%, upload your images in the context of these post/pages, and this tool will form subfolders from it. Which is great, SEO-wise.

  Or you just even ignore all that and mandate under “Build a path template” i.e. travels/france/paris-at-night to upload to that subdir of your WP-Uploads folder. (Of course you'd have to keep changing for the uploads to follow. Limiting my overall faith, that this is a stable long-term tool, despite 10.000+ active installs).

• Media File Manager allows to move already uploaded images and changes the paths in posts and pages using them accordingly. Its interface reminds of “Norton Commander 1.0” but it does the job. (Except for folder renames and deletes. So if you want to rename, better move images to a newly namend folder, then manually deleting the old.)

All of the following do NOT do the job:

• WP Media Folder is NOT changing actual direcory location, thus not actually changing paths to your images thus also not affecting image URLs. Despite its name, Folder is just their visualisation of yet-another-taxonomy. I invested $19 to learn that.

• Enhance Media Library is big, free and very popular (wordpress counts 40.000 installs) but is also not changing physical location and (thus) URLs. ? Thus the accepted answer is in my opinion wrong.

• Media File Manager advanced appears gone and is deemed dangerous!

"Functions have only READ-ONLY Database Access" If DML operations would be allowed in functions then function would be prety similar to stored Procedure.

You need to encapsulate it into another object[] array, like this:

Foo(new Object[] { new object[]{ (object)"1", (object)"2" }});

There is no need for jQuery here, regular JavaScript will do:

var str = "Abc: Lorem ipsum sit amet";
str = str.substring(str.indexOf(":") + 1);

Or, the .split() and .pop() version:

var str = "Abc: Lorem ipsum sit amet";
str = str.split(":").pop();

Or, the regex version (several variants of this):

var str = "Abc: Lorem ipsum sit amet";
str = /:(.+)/.exec(str)[1];

I had to add parseInt() to tell v-for it was looking at a number.

<li v-for="n in parseInt(count)" :key="n">{{n}}</li>

From the Active Record docs:

$this->db->where_in();

Generates a WHERE field IN ('item', 'item') SQL query joined with AND if appropriate

$names = array('Frank', 'Todd', 'James');
$this->db->where_in('username', $names);
// Produces: WHERE username IN ('Frank', 'Todd', 'James')

setup.py is Python's answer to a multi-platform installer and make file.

If you’re familiar with command line installations, then make && make install translates to python setup.py build && python setup.py install.

Some packages are pure Python, and are only byte compiled. Others may contain native code, which will require a native compiler (like gcc or cl) and a Python interfacing module (like swig or pyrex).

Note if you are on certain shared hosting sites like Dreamhost you can't disable PHP output buffering at all without going through different routes:

Changing the output buffer cache If you are using PHP FastCGI, the PHP functions flush(), ob_flush(), and ob_implicit_flush() will not function as expected. By default, output is buffered at a higher level than PHP (specifically, by the Apache module mod_deflate which is similar in form/function to mod_gzip).

If you need unbuffered output, you must either use CGI (instead of FastCGI) or contact support to request that mod_deflate is disabled for your site.

https://help.dreamhost.com/hc/en-us/articles/214202188-PHP-overview

Actually, it will takes 101 bytes.

MySQL Reference

An abstract class is one that isn't fully implemented but provides something of a blueprint for subclasses. It may be partially implemented in that it contains fully-defined concrete methods, but it can also hold abstract methods. These are methods with a signature but no method body. Any subclass must define a body for each abstract method, otherwise it too must be declared abstract. Because abstract classes cannot be instantiated, they must be extended by at least one subclass in order to be utilized. Think of the abstract class as the generic class, and the subclasses are there to fill in the missing information.

this works too, ...if you have multiple column joins

from p in context.Periods
join f in context.Facts 
on new {
    id = p.periodid,
    p.otherid
} equals new {
    f.id,
    f.otherid
} into fg
from fgi in fg.DefaultIfEmpty()
where p.companyid == 100
select f.value

As far as I can tell, this is currently not possible - a cast is always needed.

To make it possible, the .d.ts of react would need to be modified so that the signature of the onChange of a SELECT element used a new SelectFormEvent. The new event type would expose target, which exposes value. Then the code could be typesafe.

Otherwise there will always be the need for a cast to any.

I could encapsulate all that in a MYSELECT tag.

You just need to add this line to the window there:

exec (your stored proc name) (and possibly add parameters)

What is your stored proc called, and what parameters does it expect?

I think the short answer is "because it is of zero usefulness". To call an interface method, you need an instance of the type. From instance methods you can call any static methods you want to.

"no suitable driver" usually means that the syntax for the connection URL is incorrect.

Clean solution. Restore nuget packages.

One line version:

String text = ((Spinner)findViewById(R.id.spinner)).getSelectedItem().toString();

UPDATE: You can remove casting if you use SDK 26 (or newer) to compile your project.

String text = findViewById(R.id.spinner).getSelectedItem().toString();

Try this: parseInt(jQuery.offset().top, 10)

the solution to the typescript:

Step1:

npm install jquery

npm install --save-dev @types/jquery

step2: in Angular.json add:

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

or in index.html add:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>

step3: in *.component.ts where you want to use jquery

import * as $ from 'jquery';  // dont need "declare let $"

Then you can use jquery the same as javaScript. This way, VScode supports auto-suggestion by Typescript

Backup/Restore Mongodb with timing.

Backup:

sudo mongodump --db db_name --out /path_of_your_backup/`date +"%m-%d-%y"`

--db argument for databse name

--out argument for path of output

Restore:

sudo mongorestore --db db_name --drop /path_of_your_backup/01-01-19/db_name/

--drop argument for drop databse before restore

Timing:

You can use crontab for timing backup:

sudo crontab -e

It opens with editor(e.g. nano)

3 3 * * * mongodump --out /path_of_your_backup/`date +"%m-%d-%y"`

backup every day at 03:03 AM

Depending on your MongoDB database sizes you may soon run out of disk space with too many backups. That's why it's also recommended to clean the old backups regularly or to compress them. For example, to delete all the backups older than 7 days you can use the following bash command:

3 1 * * * find /path_of_your_backup/ -mtime +7 -exec rm -rf {} \;

delete all the backups older than 7 days

Good Luck.

You have compiled your code with references to the correct math.h header file, but when you attempted to link it, you forgot the option to include the math library. As a result, you can compile your .o object files, but not build your executable.

As Paul has already mentioned add "-lm" to link with the math library in the step where you are attempting to generate your executable.

In the comment, linuxD asks:

Why for sin() in <math.h>, do we need -lm option explicitly; but, not for printf() in <stdio.h>?

Because both these functions are implemented as part of the "Single UNIX Specification". This history of this standard is interesting, and is known by many names (IEEE Std 1003.1, X/Open Portability Guide, POSIX, Spec 1170).

This standard, specifically separates out the "Standard C library" routines from the "Standard C Mathematical Library" routines (page 277). The pertinent passage is copied below:

Standard C Library

The Standard C library is automatically searched by cc to resolve external references. This library supports all of the interfaces of the Base System, as defined in Volume 1, except for the Math Routines.

Standard C Mathematical Library

This library supports the Base System math routines, as defined in Volume 1. The cc option -lm is used to search this library.

The reasoning behind this separation was influenced by a number of factors:

1. The UNIX wars led to increasing divergence from the original AT&T UNIX offering.
2. The number of UNIX platforms added difficulty in developing software for the operating system.
3. An attempt to define the lowest common denominator for software developers was launched, called 1988 POSIX.
4. Software developers programmed against the POSIX standard to provide their software on "POSIX compliant systems" in order to reach more platforms.
5. UNIX customers demanded "POSIX compliant" UNIX systems to run the software.

The pressures that fed into the decision to put -lm in a different library probably included, but are not limited to:

1. It seems like a good way to keep the size of libc down, as many applications don't use functions embedded in the math library.
2. It provides flexibility in math library implementation, where some math libraries rely on larger embedded lookup tables while others may rely on smaller lookup tables (computing solutions).
3. For truly size constrained applications, it permits reimplementations of the math library in a non-standard way (like pulling out just sin() and putting it in a custom built library.

In any case, it is now part of the standard to not be automatically included as part of the C language, and that's why you must add -lm.

Your project is mostly likely targetting .NET Framework 4 Client Profile. Check the application tab in your project properties.

This question has a good answer on the different versions: Target framework, what does ".NET Framework ... Client Profile" mean?

it clears stdin buffer before reading. From the man page:

For output streams, fflush() forces a write of all user-space buffered data for the given output or update stream via the stream's underlying write function. For input streams, fflush() discards any buffered data that has been fetched from the underlying file, but has not been consumed by the application.

Note: This is Linux-specific, using fflush() on input streams is undefined by the standard, however, most implementations behave the same as in Linux.

Fixing the comparison:

• S3 is a storage facility accessible any where
• EBS is a device you can mount onto EC2
• EFS is a file system you can mount onto several EC2 instances at the same time

At this point it's a little premature to compare EFS and EBS- the performance of EFS isn't known, nor is its reliability known.

Why would you use S3?

• You don't have a need for the files to be 'local' to one or more EC2 instances.
• (effectively) infinite capacity
• built-in web serving, authentication

You can use jstack utility if you want to check the current call stack of your process.

Usage:
    jstack [-l] <pid>
        (to connect to running process)
    jstack -F [-m] [-l] <pid>
        (to connect to a hung process)
    jstack [-m] [-l] <executable> <core>
        (to connect to a core file)
    jstack [-m] [-l] [server_id@]<remote server IP or hostname>
        (to connect to a remote debug server)

Options:
    -F  to force a thread dump. Use when jstack <pid> does not respond (process is hung)
    -m  to print both java and native frames (mixed mode)
    -l  long listing. Prints additional information about locks
    -h or -help to print this help message

You are just initing in the wrong order.

     class Shape2 {
        var numberOfSides = 0
        var name: String
        init(name:String) {
            self.name = name
        }
        func simpleDescription() -> String {
            return "A shape with \(numberOfSides) sides."
        }
    }

    class Square2: Shape2 {
        var sideLength: Double

        init(sideLength:Double, name:String) {

            self.sideLength = sideLength
            super.init(name:name) // It should be behind "self.sideLength = sideLength"
            numberOfSides = 4
        }
        func area () -> Double {
            return sideLength * sideLength
        }
    }

sleep already returns 0. As such, I'm using:

while sleep 3 ; do ls -l ; done

This is a tiny bit shorter than mikhail's solution. A minor drawback is that it sleeps before running the target command for the first time.

following will show one table of dataset

DataGridView1.AutoGenerateColumns = true;
DataGridView1.DataSource = ds; // dataset
DataGridView1.DataMember = "TableName"; // table name you need to show

if you want to show multiple tables, you need to create one datatable or custom object collection out of all tables.

if two tables with same table schema

dtAll = dtOne.Copy(); // dtOne = ds.Tables[0]
dtAll.Merge(dtTwo); // dtTwo = dtOne = ds.Tables[1]

DataGridView1.AutoGenerateColumns = true;
DataGridView1.DataSource = dtAll ; // datatable

sample code to mode all tables

DataTable dtAll = ds.Tables[0].Copy();
for (var i = 1; i < ds.Tables.Count; i++)
{
     dtAll.Merge(ds.Tables[i]);
}
DataGridView1.AutoGenerateColumns = true;
DataGridView1.DataSource = dtAll ;

I know the struggle man! But I recently had it pretty much working with Workerman. If you have not stumbled upon this php framework then you better check this out!

Well, Workerman is an asynchronous event driven PHP framework for easily building fast, scalable network applications. (I just copied and pasted that from their website hahahah http://www.workerman.net/en/)

The easy way to explain this is that when it comes web socket programming all you really need to have is to have 2 files in your server or local server (wherever you are working at).

1. server.php (source code which will respond to all the client's request)

2. client.php/client.html (source code which will do the requesting stuffs)

So basically, you right the code first on you server.php and start the server. Normally, as I am using windows which adds more of the struggle, I run the server through this command --> php server.php start

Well if you are using xampp. Here's one way to do it. Go to wherever you want to put your files. In our case, we're going to the put the files in

C:/xampp/htdocs/websocket/server.php

C:/xampp/htdocs/websocket/client.php or client.html

Assuming that you already have those files in your local server. Open your Git Bash or Command Line or Terminal or whichever you are using and download the php libraries here.

https://github.com/walkor/Workerman

https://github.com/walkor/phpsocket.io

I usually download it via composer and just autoload those files in my php scripts.

And also check this one. This is really important! You need this javascript libary in order for you client.php or client.html to communicate with the server.php when you run it.

https://github.com/walkor/phpsocket.io/tree/master/examples/chat/public/socket.io-client

I just copy and pasted that socket.io-client folder on the same level as my server.php and my client.php

Here is the server.php sourcecode

<?php
require __DIR__ . '/vendor/autoload.php';

use Workerman\Worker;
use PHPSocketIO\SocketIO;

// listen port 2021 for socket.io client
$io = new SocketIO(2021);
$io->on('connection', function($socket)use($io){
    $socket->on('send message', function($msg)use($io){
        $io->emit('new message', $msg);
    });
});

Worker::runAll();

And here is the client.php or client.html sourcecode

Once again, open your command line or git bash or terminal where you put your server.php file. So in our case, that is C:/xampp/htdocs/websocket/ and typed in php server.php start and press enter.

Then go to you browser and type http://localhost/websocket/client.php to visit your site. Then just type anything to that textbox and you will see a basic php websocket on the go!

You just need to remember. In web socket programming, it just needs a server and a client. Run the server code first and the open the client code. And there you have it! Hope this helps!

Here's what I did:

• Extracted the files using WinRAR
• Made my changes to the extracted files
• Opened the original JAR file with WinRAR
• Used the ADD button to replace the files that I modified

That's it. I have tested it with my Nokia and it's working for me.

Try this : (http://jsfiddle.net/TpqVx/)

.left-div {
    float: left;
    width: 100px;
    /*height: 20px;*/
    margin-right: 8px;
    background-color: linen;
}
.right-div {

    margin-left: 108px;
    background-color: lime;
}??

<div class="left-div">
    &nbsp;
</div>
<div class="right-div">
    My requirements are <b>[A]</b> Content in the two divs should line up at the top, <b>[B]</b> Long text in right-div should not wrap underneath left-div, and <b>[C]</b> I do not want to specify a width of right-div. I don't want to set the width of right-div because this markup needs to work within different widths.
</div>
<div style='clear:both;'>&nbsp;</div>

Hints :

• Just use float:left in your left-most div only.
• No real reason to use height, but anyway...
• Good practice to use <div 'clear:both'>&nbsp;</div> after your last div.

You should create a XML file for the disabled button (drawable/btn_disable.xml)

<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid android:color="@color/grey" />
    <corners android:radius="6dp" />
</shape>

And create a selector for the button (drawable/btn_selector.xml)

<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:drawable="@drawable/btn_disable" android:state_enabled="false"/>
    <item android:drawable="@drawable/btn_default" android:state_enabled="true"/>
    <item android:drawable="@drawable/btn_default" android:state_pressed="false" />

</selector>

Add the selector to your button

<style name="srp_button" parent="@android:style/Widget.Button">
    <item name="android:background">@drawable/btn_selector</item>
</style>

Create a users file (i.e. users.txt) for mapping SVN users to Git:

user1 = First Last Name <[email protected]>
user2 = First Last Name <[email protected]>
...

You can use this one-liner to build a template from your existing SVN repository:

svn log -q | awk -F '|' '/^r/ {sub("^ ", "", $2); sub(" $", "", $2); print $2" = "$2" <"$2">"}' | sort -u > users.txt

SVN will stop if it finds a missing SVN user not in the file. But after that you can update the file and pick-up where you left off.

Now pull the SVN data from the repository:

git svn clone --stdlayout --no-metadata --authors-file=users.txt svn://hostname/path dest_dir-tmp

This command will create a new Git repository in dest_dir-tmp and start pulling the SVN repository. Note that the "--stdlayout" flag implies you have the common "trunk/, branches/, tags/" SVN layout. If your layout differs, become familiar with --tags, --branches, --trunk options (in general git svn help).

All common protocols are allowed: svn://, http://, https://. The URL should target the base repository, something like http://svn.mycompany.com/myrepo/repository. The URL string must not include /trunk, /tag or /branches.

Note that after executing this command it very often looks like the operation is "hanging/freezed", and it's quite normal that it can be stuck for a long time after initializing the new repository. Eventually you will then see log messages which indicates that it's migrating.

Also note that if you omit the --no-metadata flag, Git will append information about the corresponding SVN revision to the commit message (i.e. git-svn-id: svn://svn.mycompany.com/myrepo/<branchname/trunk>@<RevisionNumber> <Repository UUID>)

If a user name is not found, update your users.txt file then:

cd dest_dir-tmp
git svn fetch

You might have to repeat that last command several times, if you have a large project, until all of the Subversion commits have been fetched:

git svn fetch

When completed, Git will checkout the SVN trunk into a new branch. Any other branches are setup as remotes. You can view the other SVN branches with:

git branch -r

If you want to keep other remote branches in your repository, you want to create a local branch for each one manually. (Skip trunk/master.) If you don't do this, the branches won't get cloned in the final step.

git checkout -b local_branch remote_branch
# It's OK if local_branch and remote_branch are the same name

Tags are imported as branches. You have to create a local branch, make a tag and delete the branch to have them as tags in Git. To do it with tag "v1":

git checkout -b tag_v1 remotes/tags/v1
git checkout master
git tag v1 tag_v1
git branch -D tag_v1

Clone your GIT-SVN repository into a clean Git repository:

git clone dest_dir-tmp dest_dir
rm -rf dest_dir-tmp
cd dest_dir

The local branches that you created earlier from remote branches will only have been copied as remote branches into the new cloned repository. (Skip trunk/master.) For each branch you want to keep:

git checkout -b local_branch origin/remote_branch

Finally, remove the remote from your clean Git repository that points to the now deleted temporary repository:

git remote rm origin

I prefer onKeyUp since it only fires when the key is released. onKeyDown, on the other hand, will fire multiple times if for some reason the user presses and holds the key. For example, when listening for "pressing" the Enter key to make a network request, you don't want that to fire multiple times since it can be expensive.

// handler could be passed as a prop
<input type="text" onKeyUp={handleKeyPress} />

handleKeyPress(e) {
if (e.key === 'Enter') {
  // do whatever
}

}

Also, stay away from keyCode since it will be deprecated some time.

You can change from settings menu (at least from version 1.30.2 and above)...

On Mac, just hit Code > Preferences > Settings.

Then just search for "clear" and check Clear Previous Output.

Vertex *f=(findvertex(from));
if(!f) {
    cerr << "vertex not found" << endl;
    exit(1) // or return;
}

Because findVertex can return NULL if it can't find the vertex.

Otherwise this f->adj; is trying to do

NULL->adj;

Which causes access violation.

You possibly do not have create permissions to the folder. So WinSCP fails to create a temporary file for the transfer.

You have two options:

• Grant write permissions to the folder to the user or group you log in with (myuser), or change the ownership of the folder to the user, or

• Disable a transfer to temporary file.

  In Preferences, go to Transfer > Endurance page and in Enable transfer resume/transfer to temporary file name for select Disable:

  

You can test the user agent string:

/**
 * Determine the mobile operating system.
 * This function returns one of 'iOS', 'Android', 'Windows Phone', or 'unknown'.
 *
 * @returns {String}
 */
function getMobileOperatingSystem() {
  var userAgent = navigator.userAgent || navigator.vendor || window.opera;

      // Windows Phone must come first because its UA also contains "Android"
    if (/windows phone/i.test(userAgent)) {
        return "Windows Phone";
    }

    if (/android/i.test(userAgent)) {
        return "Android";
    }

    // iOS detection from: http://stackoverflow.com/a/9039885/177710
    if (/iPad|iPhone|iPod/.test(userAgent) && !window.MSStream) {
        return "iOS";
    }

    return "unknown";
}

For situations where there are multiple services in the same building you could offset the markers just a little, (say by .001 degree), in a radius from the actual point. This should also produce a nice visual effect.

The following code works for me.

//escape the double quotes in json string
String payload="{\"jsonrpc\":\"2.0\",\"method\":\"changeDetail\",\"params\":[{\"id\":11376}],\"id\":2}";
String requestUrl="https://git.eclipse.org/r/gerrit/rpc/ChangeDetailService";
sendPostRequest(requestUrl, payload);

method implementation:

public static String sendPostRequest(String requestUrl, String payload) {
    try {
        URL url = new URL(requestUrl);
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();

        connection.setDoInput(true);
        connection.setDoOutput(true);
        connection.setRequestMethod("POST");
        connection.setRequestProperty("Accept", "application/json");
        connection.setRequestProperty("Content-Type", "application/json; charset=UTF-8");
        OutputStreamWriter writer = new OutputStreamWriter(connection.getOutputStream(), "UTF-8");
        writer.write(payload);
        writer.close();
        BufferedReader br = new BufferedReader(new InputStreamReader(connection.getInputStream()));
        StringBuffer jsonString = new StringBuffer();
        String line;
        while ((line = br.readLine()) != null) {
                jsonString.append(line);
        }
        br.close();
        connection.disconnect();
        return jsonString.toString();
    } catch (Exception e) {
            throw new RuntimeException(e.getMessage());
    }

}

You can use the following code in modern browsers to efficiently check the storage quota (total & used) in real-time:

if ('storage' in navigator && 'estimate' in navigator.storage) {
        navigator.storage.estimate()
            .then(estimate => {
                console.log("Usage (in Bytes): ", estimate.usage,
                            ",  Total Quota (in Bytes): ", estimate.quota);
            });
}

I think the accepted answer is an awful way of handling this.

I don't know what the use case is, but please consider a protected method in the base class

@protected
void doSomething() {
}

and override it in the derived class.

When the event occurs, just call this method in the base class. The correct 'active' class will handle it then. The class itself can then check if it is not Paused().

Better yet, use an event bus like GreenRobot's, Square's, but that one is deprecated and suggests using RxJava

Why not keep it simple?!

GB=DF.groupby([(DF.index.year),(DF.index.month)]).sum()

giving you,

print(GB)
        abc  xyz
2013 6   80  250
     8   40   -5
2014 1   25   15
     2   60   80

and then you can plot like asked using,

GB.plot('abc','xyz',kind='scatter')

A long shot, but double-check with Firebug (or similar) that you aren't accidentally inheriting the following rule:

white-space:nowrap;

This may override your specified line break behaviour.

Put file inside while True like so

while True:
     f = open('torecv.png','wb')
     c, addr = s.accept()     # Establish connection with client.
     print 'Got connection from', addr
     print "Receiving..."
     l = c.recv(1024)
     while (l):
         print "Receiving..."
         f.write(l)
         l = c.recv(1024)
     f.close()
     print "Done Receiving"
     c.send('Thank you for connecting')
     c.close()   

The tools sed or tr will do this for you by swapping the whitespace for nothing

sed 's/ //g'

tr -d ' '

Example:

$ echo "   3918912k " | sed 's/ //g'
3918912k

I am trying this and so far it works (but I am only on Android/Phonegap so caveat emptor)

  function filterEvent( ob, ev ) {
      if (ev.type == "touchstart") {
          ob.off('click').on('click', function(e){ e.preventDefault(); });
      }
  }
  $('#keypad').on('touchstart click', '.number, .dot', function(event) {
      filterEvent( $('#keypad'), event );
      console.log( event.type );  // debugging only
           ... finish handling touch events...
  }

I don't like the fact that I am re-binding handlers on every touch, but all things considered touches don't happen very often (in computer time!)

I have a TON of handlers like the one for '#keypad' so having a simple function that lets me deal with the problem without too much code is why I went this way.

Otherwise... if

getenforce

returns

Enforcing

Then maybe you should call

setenforce 0 
mount -o rw,remount /system 
setenforce 1

I did a little experimenting to see if I could keep the database name as part of the url. I prefer the promise syntax but it should still work for the callback syntax. Notice below that client.db() is called without passing any parameters.

MongoClient.connect(
    'mongodb://localhost:27017/mytestingdb', 
    { useNewUrlParser: true}
)
.then(client => {

    // The database name is part of the url.  client.db() seems 
    // to know that and works even without a parameter that 
    // relays the db name.
    let db = client.db(); 

    console.log('the current database is: ' + db.s.databaseName);
    // client.close() if you want to

})
.catch(err => console.log(err));

My package.json lists monbodb ^3.2.5.

The 'useNewUrlParser' option is not required if you're willing to deal with a deprecation warning. But it is wise to use at this point until version 4 comes out where presumably the new driver will be the default and you won't need the option anymore.

First of all you cannot change the memory settings only for a tomcat application but rather for all tomcat instance.

If you are running tomcat from console (using startup.bat) you'll need to edit catalina.bat and play around with CATALINA_OPTS. For example:

set CATALINA_OPTS=-Xms512m -Xmx512m

Restarting tomcat will apply the new settings.

If you are still getting OutOfMemoryError you need to know how much memory does your application need at that particular moment (nom.tam.util.ArrayFuncs...). You'll either have to optimize the application or simply increase the memory provided to tomcat.

This is my original post, which sparked some debate... because it is wrong:

The switch statement is not the same thing as a big if-else statement. Each case must be unique and evaluated statically. The switch statement does a constant time branch regardless of how many cases you have. The if-else statement evaluates each condition until it finds one that is true.

In fact, the C# switch statement is not always a constant time branch.

In some cases the compiler will use a CIL switch statement which is indeed a constant time branch using a jump table. However, in sparse cases as pointed out by Ivan Hamilton the compiler may generate something else entirely.

This is actually quite easy to verify by writing various C# switch statements, some sparse, some dense, and looking at the resulting CIL with the ildasm.exe tool.

You could also use a pseudo class selector in your CSS like this:

.desc:not(:first-child) {
    display: none;
}

That will not apply the class to the first element with the class .desc.

Here's a JSFiddle with an example: http://jsfiddle.net/YYTFT/, and this is a good source to explain pseudo class selectors: http://css-tricks.com/pseudo-class-selectors/

You could try qemu, which is what the Android emulator uses. I believe it actually emulates the ARM hardware.

FOR SQL SERVER

EXEC sp_addlinkedserver @server='servername' 

No need to specify other parameters. You can go through this article.

Simply use substr for string

ex.

var str = "Hello world!";
var res = str.substr(1, str.length);

Result = ello world!

SELECT COUNT(*)
FROM `gd`
GROUP BY gid
HAVING COUNT(gid) > 10
ORDER BY lastupdated DESC;

EDIT (if you just want the gids):

SELECT MIN(gid)
FROM `gd`
GROUP BY gid
HAVING COUNT(gid) > 10
ORDER BY lastupdated DESC

I agree - it's probably safer to use a GET request if you're just passing data in the URL and not in the body. See this similar question for some additional views on the whole POST+GET concept.

If anyone is looking for a VB.Net answer (as I was initially), here it is:

Public Function IsSatisfied() As Expression(Of Func(Of Charity, String, String, Boolean))

Return Function(charity, name, referenceNumber) (String.IsNullOrWhiteSpace(name) Or
                                                         charity.registeredName.ToLower().Contains(name.ToLower()) Or
                                                         charity.alias.ToLower().Contains(name.ToLower()) Or
                                                         charity.charityId.ToLower().Contains(name.ToLower())) And
                                                    (String.IsNullOrEmpty(referenceNumber) Or
                                                     charity.charityReference.ToLower().Contains(referenceNumber.ToLower()))

contextlib.nested supports this:

import contextlib

with contextlib.nested(open("out.txt","wt"), open("in.txt")) as (file_out, file_in):

   ...

Update:
To quote the documentation, regarding contextlib.nested:

Deprecated since version 2.7: The with-statement now supports this functionality directly (without the confusing error prone quirks).

Tried everything but on Visual Studio 2015 Community edition I got it working when I installed MySQL for Visual Studio 1.2.4+ from http://dev.mysql.com/downloads/windows/visualstudio/ At time of writing I could download 1.2.6 which worked for me.

Release notes of 1.2.4 which adds support for VS2015 can be found at http://forums.mysql.com/read.php?3,633391

A stored procedure is a set of precompiled SQL statements that are used to perform a special task.

Example: If I have an Employee table

Employee ID  Name       Age  Mobile
---------------------------------------
001          Sidheswar  25   9938885469
002          Pritish    32   9178542436

First I am retrieving the Employee table:

Create Procedure Employee details
As
Begin
    Select * from Employee
End

To run the procedure on SQL Server:

Execute   Employee details

--- (Employee details is a user defined name, give a name as you want)

Then second, I am inserting the value into the Employee Table

Create Procedure employee_insert
    (@EmployeeID int, @Name Varchar(30), @Age int, @Mobile int)
As
Begin
    Insert Into Employee
    Values (@EmployeeID, @Name, @Age, @Mobile)
End

To run the parametrized procedure on SQL Server:

Execute employee_insert 003,’xyz’,27,1234567890

  --(Parameter size must be same as declared column size)

Example: @Name Varchar(30)

In the Employee table the Name column's size must be varchar(30).

Simply, double shift then type Assets Folder

choose it to be created in the correct place

Use the error handler like this:

$('#image_id').error(function() {
  alert('Image does not exist !!');
});

If the image cannot be loaded (for example, because it is not present at the supplied URL), the alert is displayed:

Update:

I think using:

$.ajax({url:'somefile.dat',type:'HEAD',error:do_something});

would be enough to check for a 404.

More Readings:

• http://www.jibbering.com/2002/4/httprequest.html
• http://www.ibm.com/developerworks/web/library/wa-ajaxintro3/

Update 2:

Your code should be like this:

$(this).error(function() {
  alert('Image does not exist !!');
});

No need for these lines and that won't check if the remote file exists anyway:

var imgcheck = imgsrc.width;    

if (imgcheck==0) {
  alert("You have a zero size image");
} else { 
  //execute the rest of code here 
}

The following line will start reading a number (%d) followed by anything different from tabs or newlines (%[^\t\n]).

sscanf("19 cool kid", "%d %[^\t\n]", &age, buffer);

one url to the same view! like so!

urls.py

url(r'^$', views.landing.as_view(), name = 'landing'),

views.py

class landing(View):
        template_name = '/home.html'
        form_class1 = forms.pynamehere1
        form_class2 = forms.pynamehere2
            def get(self, request):
                form1 = self.form_class1(None)
                form2 = self.form_class2(None)
                return render(request, self.template_name, { 'register':form1, 'login':form2,})

             def post(self, request):
                 if request.method=='POST' and 'htmlsubmitbutton1' in request.POST:
                        ## do what ever you want to do for first function ####
                 if request.method=='POST' and 'htmlsubmitbutton2' in request.POST:
                         ## do what ever you want to do for second function ####
                        ## return def post###  
                 return render(request, self.template_name, {'form':form,})

/home.html
    <!-- #### form 1 #### -->
    <form action="" method="POST" >
      {% csrf_token %}
      {{ register.as_p }}
    <button type="submit" name="htmlsubmitbutton1">Login</button>
    </form>
    <!--#### form 2 #### -->
    <form action="" method="POST" >
      {% csrf_token %}
      {{ login.as_p }}
    <button type="submit" name="htmlsubmitbutton2">Login</button>
    </form>

This is not perfect but it works for me right now. I don't know if it has O(n) running time btw (still studying it ^^) but it uses one additional array to fulfill the task.

It is probably not the best answer to your problem because i use a dest string to save the reversed version instead of replacing each words in the source string. The problem is that i use a local stack variable named buf to copy all the words in and i can not copy but into the source string as this would lead to a crash if the source string is const char * type.

But it was my first attempt to write s.th. like this :) Ok enough blablub. here is code:

#include <iostream>
using namespace std;

void reverse(char *des, char * const s);
int main (int argc, const char * argv[])
{    
    char* s = (char*)"reservered. rights All Saints. The 2011 (c) Copyright 11/10/11 on Pfundstein Markus by Created";
    char *x = (char*)"Dogfish! White-spotted Shark, Bullhead";

    printf("Before: |%s|\n", x);
    printf("Before: |%s|\n", s);

    char *d = (char*)malloc((strlen(s)+1)*sizeof(char));  
    char *i = (char*)malloc((strlen(x)+1)*sizeof(char));

    reverse(d,s);
    reverse(i,x);

    printf("After: |%s|\n", i);
    printf("After: |%s|\n", d);

    free (i);
    free (d);

    return 0;
}

void reverse(char *dest, char *const s) {
    // create a temporary pointer
    if (strlen(s)==0) return;
    unsigned long offset = strlen(s)+1;

    char *buf = (char*)malloc((offset)*sizeof(char));
    memset(buf, 0, offset);

    char *p;
    // iterate from end to begin and count how much words we have
    for (unsigned long i = offset; i != 0; i--) {
        p = s+i;
        // if we discover a whitespace we know that we have a whole word
        if (*p == ' ' || *p == '\0') {
            // we increment the counter
            if (*p != '\0') {
                // we write the word into the buffer
                ++p;
                int d = (int)(strlen(p)-strlen(buf));
                strncat(buf, p, d);
                strcat(buf, " ");
            }
        }
    }

    // copy the last word
    p -= 1;
    int d = (int)(strlen(p)-strlen(buf));
    strncat(buf, p, d);
    strcat(buf, "\0");

    // copy stuff to destination string
    for (int i = 0; i < offset; ++i) {
        *(dest+i)=*(buf+i);
    }

    free(buf);
}

At this moment, 2020-10-17, if you select a text element and hit CTRL+SHIFT+ALT+M it will highlight every instance within the code chunk.

My suggestion does not come from Terminal; however, this is a much easier way.

For .bat files, you can run them through Wine. Use this video to help you install it: https://www.youtube.com/watch?v=DkS8i_blVCA. This video will explain how to install, setup and use Wine. It is as simple as opening the .bat file in Wine itself, and it will run just as it would on Windows.

Through this, you can also run .exe files, as well .sh files.

This is much simpler than trying to work out all kinds of terminal code.

Add the 'columns' parameter:

frame = pd.DataFrame({
        'one thing':[1,2,3,4],
        'second thing':[0.1,0.2,1,2],
        'other thing':['a','e','i','o']},
        columns=['one thing', 'second thing', 'other thing']
)

I personally prefer the + operator than append:

for i in range(0, n):

    list1 += [[i]]

But this is creating a new list every time, so might not be the best if performance is critical.

In my case, Python was unable to find it because I'd put the code inside a module with hyphens, e.g. my-module. When I changed it to my_module it worked.

If your within SSMS you might find it easier to use:

SELECT @@Version

Or about the best module I have found http://pypi.python.org/pypi/colorama

Try this:

Calendar calendar = Calendar.getInstance();
calendar.setTime(yourdate);
int hours = calendar.get(Calendar.HOUR_OF_DAY);
int minutes = calendar.get(Calendar.MINUTE);
int seconds = calendar.get(Calendar.SECOND);

Edit:

hours, minutes, seconds

above will be the hours, minutes and seconds after converting yourdate to System Timezone!

You can also make the python script run as a service using a shell script. First create a shell script to run the python script like this (scriptname arbitary name)

#!/bin/sh
script='/home/.. full path to script'
/usr/bin/python $script &

now make a file in /etc/init.d/scriptname

#! /bin/sh

PATH=/bin:/usr/bin:/sbin:/usr/sbin
DAEMON=/home/.. path to shell script scriptname created to run python script
PIDFILE=/var/run/scriptname.pid

test -x $DAEMON || exit 0

. /lib/lsb/init-functions

case "$1" in
  start)
     log_daemon_msg "Starting feedparser"
     start_daemon -p $PIDFILE $DAEMON
     log_end_msg $?
   ;;
  stop)
     log_daemon_msg "Stopping feedparser"
     killproc -p $PIDFILE $DAEMON
     PID=`ps x |grep feed | head -1 | awk '{print $1}'`
     kill -9 $PID       
     log_end_msg $?
   ;;
  force-reload|restart)
     $0 stop
     $0 start
   ;;
  status)
     status_of_proc -p $PIDFILE $DAEMON atd && exit 0 || exit $?
   ;;
 *)
   echo "Usage: /etc/init.d/atd {start|stop|restart|force-reload|status}"
   exit 1
  ;;
esac

exit 0

Now you can start and stop your python script using the command /etc/init.d/scriptname start or stop.

Here's a good discussion on this:

• How to use JDK 1.6 in 1.5 compliance mode

Basically you should

1. Download and install the 1.5 JDK. (download link)
2. In Eclipse, Go to Window ? Preferences ? Java ? Installed JREs.
3. Add the 1.5 JDK to the list.
4. Select 1.5 as Compiler Compliance Level.

Unfortunately there is currently no designer support (unlike for SQL Server 2005) for building relationships between tables in SQL Server CE. To build relationships you need to use SQL commands such as:

ALTER TABLE Orders
ADD CONSTRAINT FK_Customer_Order
FOREIGN KEY (CustomerId) REFERENCES Customers(CustomerId)

If you are doing CE development, i would recomend this FAQ:

EDIT: In Visual Studio 2008 this is now possible to do in the GUI by right-clicking on your table.

Just do this:

git checkout master

Or, if you have changes that you want to keep, do this:

git checkout -b temp
git checkout -B master temp

This is my 2nd iteration of the code. Because MemoryCache is thread safe you don't need to lock on the initial read, you can just read and if the cache returns null then do the lock check to see if you need to create the string. It greatly simplifies the code.

const string CacheKey = "CacheKey";
static readonly object cacheLock = new object();
private static string GetCachedData()
{

    //Returns null if the string does not exist, prevents a race condition where the cache invalidates between the contains check and the retreival.
    var cachedString = MemoryCache.Default.Get(CacheKey, null) as string;

    if (cachedString != null)
    {
        return cachedString;
    }

    lock (cacheLock)
    {
        //Check to see if anyone wrote to the cache while we where waiting our turn to write the new value.
        cachedString = MemoryCache.Default.Get(CacheKey, null) as string;

        if (cachedString != null)
        {
            return cachedString;
        }

        //The value still did not exist so we now write it in to the cache.
        var expensiveString = SomeHeavyAndExpensiveCalculation();
        CacheItemPolicy cip = new CacheItemPolicy()
                              {
                                  AbsoluteExpiration = new DateTimeOffset(DateTime.Now.AddMinutes(20))
                              };
        MemoryCache.Default.Set(CacheKey, expensiveString, cip);
        return expensiveString;
    }
}

EDIT: The below code is unnecessary but I wanted to leave it to show the original method. It may be useful to future visitors who are using a different collection that has thread safe reads but non-thread safe writes (almost all of classes under the System.Collections namespace is like that).

Here is how I would do it using ReaderWriterLockSlim to protect access. You need to do a kind of "Double Checked Locking" to see if anyone else created the cached item while we where waiting to to take the lock.

const string CacheKey = "CacheKey";
static readonly ReaderWriterLockSlim cacheLock = new ReaderWriterLockSlim();
static string GetCachedData()
{
    //First we do a read lock to see if it already exists, this allows multiple readers at the same time.
    cacheLock.EnterReadLock();
    try
    {
        //Returns null if the string does not exist, prevents a race condition where the cache invalidates between the contains check and the retreival.
        var cachedString = MemoryCache.Default.Get(CacheKey, null) as string;

        if (cachedString != null)
        {
            return cachedString;
        }
    }
    finally
    {
        cacheLock.ExitReadLock();
    }

    //Only one UpgradeableReadLock can exist at one time, but it can co-exist with many ReadLocks
    cacheLock.EnterUpgradeableReadLock();
    try
    {
        //We need to check again to see if the string was created while we where waiting to enter the EnterUpgradeableReadLock
        var cachedString = MemoryCache.Default.Get(CacheKey, null) as string;

        if (cachedString != null)
        {
            return cachedString;
        }

        //The entry still does not exist so we need to create it and enter the write lock
        var expensiveString = SomeHeavyAndExpensiveCalculation();
        cacheLock.EnterWriteLock(); //This will block till all the Readers flush.
        try
        {
            CacheItemPolicy cip = new CacheItemPolicy()
            {
                AbsoluteExpiration = new DateTimeOffset(DateTime.Now.AddMinutes(20))
            };
            MemoryCache.Default.Set(CacheKey, expensiveString, cip);
            return expensiveString;
        }
        finally 
        {
            cacheLock.ExitWriteLock();
        }
    }
    finally
    {
        cacheLock.ExitUpgradeableReadLock();
    }
}

After trying a skeleton project called "jsf-blank", which did not demonstrate this problem with xhtml files; I concluded that there was an unknown problem in my project. My solution may not have been too elegant, but it saved time. I backed up the code and other files I'd already developed, deleted the project, and started over - recreated the project. So far, I've added back most of the files and it looks pretty good.

Try to use the DataColumn.SetOrdinal method. For example:

dataTable.Columns["Qty"].SetOrdinal(0);
dataTable.Columns["Unit"].SetOrdinal(1); 

UPDATE: This answer received much more attention than I expected. To avoid confusion and make it easier to use I decided to create an extension method for column ordering in DataTable:

Extension method:

public static class DataTableExtensions
{
    public static void SetColumnsOrder(this DataTable table, params String[] columnNames)
    {
        int columnIndex = 0;
        foreach(var columnName in columnNames)
        {
            table.Columns[columnName].SetOrdinal(columnIndex);
            columnIndex++;
        }
    }
}

Usage:

table.SetColumnsOrder("Qty", "Unit", "Id");

or

table.SetColumnsOrder(new string[]{"Qty", "Unit", "Id"});

For me the solution was easy, there was no room left on drive C, once deleted some old files i was able to perform IISReset and all the services started successfully.

var elm = document.createElement("div");
var jelm = $(elm);//convert to jQuery Element
var htmlElm = jelm[0];//convert to HTML Element

This should do:

Assembly assem = Assembly.GetExecutingAssembly();
AssemblyName aName = assem.GetName();
return aName.Version.ToString();

I was comparing worldcitiesdatabae.info with www.worldcitiesdatabase.com and it appears the latter one to be more resourceful. However, maxmind has a free database so then why buy a cities database. Just get the free one and there is lot of help available on internet about maxmind db. If you put in extra efforts then you can save those few bucks :)

Most of the answers here are wrong. The right answer is it depends. For example, here are two C functions which walks through a tree. First the recursive one:

static
void mm_scan_black(mm_rc *m, ptr p) {
    SET_COL(p, COL_BLACK);
    P_FOR_EACH_CHILD(p, {
        INC_RC(p_child);
        if (GET_COL(p_child) != COL_BLACK) {
            mm_scan_black(m, p_child);
        }
    });
}

And here is the same function implemented using iteration:

static
void mm_scan_black(mm_rc *m, ptr p) {
    stack *st = m->black_stack;
    SET_COL(p, COL_BLACK);
    st_push(st, p);
    while (st->used != 0) {
        p = st_pop(st);
        P_FOR_EACH_CHILD(p, {
            INC_RC(p_child);
            if (GET_COL(p_child) != COL_BLACK) {
                SET_COL(p_child, COL_BLACK);
                st_push(st, p_child);
            }
        });
    }
}

It's not important to understand the details of the code. Just that p are nodes and that P_FOR_EACH_CHILD does the walking. In the iterative version we need an explicit stack st onto which nodes are pushed and then popped and manipulated.

The recursive function runs much faster than the iterative one. The reason is because in the latter, for each item, a CALL to the function st_push is needed and then another to st_pop.

In the former, you only have the recursive CALL for each node.

Plus, accessing variables on the callstack is incredibly fast. It means you are reading from memory which is likely to always be in the innermost cache. An explicit stack, on the other hand, has to be backed by malloc:ed memory from the heap which is much slower to access.

With careful optimization, such as inlining st_push and st_pop, I can reach roughly parity with the recursive approach. But at least on my computer, the cost of accessing heap memory is bigger than the cost of the recursive call.

But this discussion is mostly moot because recursive tree walking is incorrect. If you have a large enough tree, you will run out of callstack space which is why an iterative algorithm must be used.

I have been struggling with VS2010/DNFW 4.5 integration and have finally got this working. Starting in VS 2008, a cache of assemblies was introduced that is used by Visual Studio called the "Referenced Assemblies". This file cache for VS 2010 is located at \Reference Assemblies\Microsoft\Framework.NetFramework\v4.0. Visual Studio loads framework assemblies from this location instead of from the framework installation directory. When Microsoft says that VS 2010 does not support DNFW 4.5 what they mean is that this directory does not get updated when DNFW 4.5 is installed. Once you have replace the files in this location with the updated DNFW 4.5 files, you will find that VS 2010 will happily function with DNFW 4.5.

int a,b,c,d;
if(scanf("%d %d %d %d",&a,&b,&c,&d) == 4) {
   //read the 4 integers
} else {
   puts("Error. Please supply 4 integers");
}

For SBT use below mergeStrategy in build.sbt

mergeStrategy in assembly <<= (mergeStrategy in assembly) { (old) => {
    case PathList("META-INF", "services", "org.apache.hadoop.fs.FileSystem") => MergeStrategy.filterDistinctLines
    case s => old(s)
  }
}

If the line you want to delete is based on the content of the line:

string line = null;
string line_to_delete = "the line i want to delete";

using (StreamReader reader = new StreamReader("C:\\input")) {
    using (StreamWriter writer = new StreamWriter("C:\\output")) {
        while ((line = reader.ReadLine()) != null) {
            if (String.Compare(line, line_to_delete) == 0)
                continue;

            writer.WriteLine(line);
        }
    }
}

Or if it is based on line number:

string line = null;
int line_number = 0;
int line_to_delete = 12;

using (StreamReader reader = new StreamReader("C:\\input")) {
    using (StreamWriter writer = new StreamWriter("C:\\output")) {
        while ((line = reader.ReadLine()) != null) {
            line_number++;

            if (line_number == line_to_delete)
                continue;

            writer.WriteLine(line);
        }
    }
}

Make sure you are loading those modules (myApp.services and myApp.directives) as dependencies of your main app module, like this:

angular.module('myApp', ['myApp.directives', 'myApp.services']);

plunker: http://plnkr.co/edit/wxuFx6qOMfbuwPq1HqeM?p=preview

Named tuples were added in 2.6 for this purpose. Also see os.stat for a similar builtin example.

>>> import collections
>>> Point = collections.namedtuple('Point', ['x', 'y'])
>>> p = Point(1, y=2)
>>> p.x, p.y
1 2
>>> p[0], p[1]
1 2

In recent versions of Python 3 (3.6+, I think), the new typing library got the NamedTuple class to make named tuples easier to create and more powerful. Inheriting from typing.NamedTuple lets you use docstrings, default values, and type annotations.

Example (From the docs):

class Employee(NamedTuple):  # inherit from typing.NamedTuple
    name: str
    id: int = 3  # default value

employee = Employee('Guido')
assert employee.id == 3

Provided you're working in node or a browser with BigInt support, this version cuts costs by saving the expensive string construction for the very end:

const zero = 0n
const shift = 8n

function asciiToBinary (str) {
  const len = str.length
  let n = zero
  for (let i = 0; i < len; i++) {
    n = (n << shift) + BigInt(str.charCodeAt(i))
  }
  return n.toString(2).padStart(len * 8, 0)
}

It's about twice as fast as the other solutions mentioned here including this simple es6+ implementation:

const toBinary = s => [...s]
  .map(x => x
    .codePointAt()
    .toString(2)
    .padStart(8,0)
  )
  .join('')

If you need to handle unicode characters, here's this guy:

const zero = 0n
const shift = 8n
const bigShift = 16n
const byte = 255n

function unicodeToBinary (str) {
  const len = str.length
  let n = zero
  for (let i = 0; i < len; i++) {
    const bits = BigInt(str.codePointAt(i))
    n = (n << (bits > byte ? bigShift : shift)) + bits
  }
  const bin = n.toString(2)
  return bin.padStart(8 * Math.ceil(bin.length / 8), 0)
}

set the wrapper to height 100%

.vwrapper {
  display: flex;
  flex-direction: column;

  flex-wrap: nowrap;
  justify-content: flex-start;
  align-items: stretch;
  align-content: stretch;

  height: 100%;
}

and set the 3rd row to flex-grow

#row3 {
   background-color: green;
   flex: 1 1 auto;
   display: flex;
}

Of course, you may write a recursive algorithm in Batch that gives you exact control of what you do in every nested subdirectory:

@echo off
set mypath=
call :treeProcess
goto :eof

:treeProcess
setlocal
for %%f in (*.txt) do echo %mypath%%%f
for /D %%d in (*) do (
    set mypath=%mypath%%%d\
    cd %%d
    call :treeProcess
    cd ..
)
endlocal
exit /b

Ultimately, the filter that is displayed in the Browse window is set by the browser. You can specify all of the filters you want in the Accept attribute, but you have no guarantee that your user's browser will adhere to it.

Your best bet is to do some kind of filtering in the back end on the server.

In order to reference an external library in a project File -> Settings -> Project -> Project structure -> select the folder and mark as a source

You need to include the protocol scheme:

'http://192.168.1.61:8080/api/call'

Without the http:// part, requests has no idea how to connect to the remote server.

Note that the protocol scheme must be all lowercase; if your URL starts with HTTP:// for example, it won’t find the http:// connection adapter either.

Because you didn't specify the Header.

I've added an extended example:

var request = (HttpWebRequest)WebRequest.Create(strServer + strURL.Split('&')[1].ToString());

Header(ref request, p_Method);

And the method Header:

private void Header(ref HttpWebRequest p_request, string p_Method)
{
    p_request.ContentType = "application/x-www-form-urlencoded";
    p_request.Method = p_Method;
    p_request.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows CE)";
    p_request.Host = strServer.Split('/')[2].ToString();
    p_request.Accept = "*/*";
    if (String.IsNullOrEmpty(strURLReferer))
    {
        p_request.Referer = strServer;
    }
    else
    {
        p_request.Referer = strURLReferer;
    }
    p_request.Headers.Add("Accept-Language", "en-us\r\n");
    p_request.Headers.Add("UA-CPU", "x86 \r\n");
    p_request.Headers.Add("Cache-Control", "no-cache\r\n");
    p_request.KeepAlive = true;
}

I created a simple library to handle this. it can also detect more than two clicks (it all depends on you). after you import the ClickCounter class, here is how you use it to detect single and multiple clicks:

ClickCounter counter = new ClickCounter();


view.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        counter.addClick();  // submits click to be counted
    }
});

counter.setClickCountListener(new ClickCounter.ClickCountListener() {
    @Override
    public void onClickingCompleted(int clickCount) {
        rewardUserWithClicks(clickCount); // Thats All!!
    }
}); 

A good jQuery option to do this is through FormData. This method is also suited when sending files through a form!

<form id='test' method='post' enctype='multipart/form-data'>
   <input type='text' name='testinput' id='testinput'>
   <button type='submit'>submit</button>
</form>

Your send function in jQuery would look like this:

$( 'form#test' ).submit( function(){
   var data = new FormData( $( 'form#test' )[ 0 ] );

   $.ajax( {
      processData: false,
      contentType: false,

      data: data,
      dataType: 'json',
      type: $( this ).attr( 'method' );
      url: 'yourapi.php',
      success: function( feedback ){
         console.log( "the feedback from your API: " + feedback );
      }
});

to add data to your form you can either use a hidden input in your form, or you add it on the fly:

var data = new FormData( $( 'form#test' )[ 0 ] );
data.append( 'command', 'value_for_command' );

maybe you can try using

SELECT user_name
FROM user_master
WHERE upper(user_name) LIKE '%ME%'

Update

While my original answer below is still valid and might be helpful to understand the cause for DNS based URL forwarding not being available via Amazon Route 53 out of the box, I highly recommend checking out Vivek M. Chawla's utterly smart indirect solution via the meanwhile introduced Amazon S3 Support for Website Redirects and achieving a self contained server less and thus free solution within AWS only like so.

• Implementing an automated solution to generate such redirects is left as an exercise for the reader, but please pay tribute to Vivek's epic answer by publishing your solution ;)

Original Answer

Nettica must be running a custom redirection solution for this, here is the problem:

You could create a CNAME alias like aws.example.com for myaccount.signin.aws.amazon.com, however, DNS provides no official support for aliasing a subdirectory like console in this example.

• It's a pity that AWS doesn't appear to simply do this by default when hitting https://myaccount.signin.aws.amazon.com/ (I just tried), because it would solve you problem right away and make a lot of sense in the first place; besides, it should be pretty easy to configure on their end.

For that reason a few DNS providers have apparently implemented a custom solution to allow redirects to subdirectories; I venture the guess that they are basically facilitating a CNAME alias for a domain of their own and are redirecting again from there to the final destination via an immediate HTTP 3xx Redirection.

So to achieve the same result, you'd need to have a HTTP service running performing these redirects, which is not the simple solution one would hope for of course. Maybe/Hopefully someone can come up with a smarter approach still though.

private and protected access modifiers are one and same only that protected members of the base class can be accessed outside the scope of the base class in the child(derived)class. It also applies the same to inheritance . But with the private modifier the members of the base class can only be accessed in the scope or code of the base class and its friend functions only''''

Yes. In Ruby the not equal to operator is:

!=

You can get a full list of ruby operators here: https://www.tutorialspoint.com/ruby/ruby_operators.htm.

You can use .is(':visible')

Selects all elements that are visible.

For example:

if($('#selectDiv').is(':visible')){

Also, you can get the div which is visible by:

$('div:visible').callYourFunction();

Live example:

console.log($('#selectDiv').is(':visible'));_x000D_
console.log($('#visibleDiv').is(':visible'));

#selectDiv {_x000D_
  display: none;  _x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div id="selectDiv"></div>_x000D_
<div id="visibleDiv"></div>

String.prototype.includes is, as you write, not supported in Internet Explorer (or Opera).

Instead you can use String.prototype.indexOf. #indexOf returns the index of the first character of the substring if it is in the string, otherwise it returns -1. (Much like the Array equivalent)

var myString = 'this is my string';
myString.indexOf('string');
// -> 11

myString.indexOf('hello');
// -> -1

MDN has a polyfill for includes using indexOf: https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/String/includes#Polyfill

EDIT: Opera supports includes as of version 28.

EDIT 2: Current versions of Edge supports the method. (as of 2019)

Just change your syntax ever so slightly:

CASE WHEN STATE = 2 AND RetailerProcessType = 1 THEN '"AUTHORISED"'
     WHEN STATE = 1 AND RetailerProcessType = 2 THEN '"PENDING"'
     WHEN STATE = 2 AND RetailerProcessType = 2 THEN '"AUTHORISED"'
     ELSE '"DECLINED"'
END

If you don't put the field expression before the CASE statement, you can put pretty much any fields and comparisons in there that you want. It's a more flexible method but has slightly more verbose syntax.

int findMin(int t1, int t2, int t3, int t4, int t5)
{
    int min;

    min = t1;
    if (t2 < min)
        min = t2;
    if (t3 < min)
        min = t3;
    if (t4 < min)
        min = t4;
    if (t5 < min)
        min = t5;

    return min;
}

int findMax(int t1, int t2, int t3, int t4, int t5)
{
    int max;

    max = t1;
    if (t2 > max)
        max = t2;
    if (t3 > max)
        max = t3;
    if (t4 > max)
        max = t4;
    if (t5 > max)
        max = t5;

For TortoiseGit 1.8.1.2 or later, there is a GUI to switch on/off credential helper.

It supports git-credential-wincred and git-credential-winstore.

TortoiseGit 1.8.16 add support for git-credential-manager (Git Credential Manager, the successor of git-credential-winstore)

For the first time you sync you are asked for user and password, you enter them and they will be saved to Windows credential store. It won't ask for user or password the next time you sync.

To use: Right click → TortoiseGit → Settings → Git → Credential. Select Credential helper: wincred - this repository only / wincred - current Windows user

Starting with C# 8.0, you can use the ??= operator to replace the code of the form

if (variable is null)
{
    variable = expression;
}

with the following code:

variable ??= expression;

To print to any printer on the network you can send a PJL/PCL print job directly to a network printer on port 9100.

Please have a look at the below link that should give a good start:

http://frank.zinepal.com/printing-directly-to-a-network-printer

Also, If there is a way to call Windows cmd you can use FTP put to print your page on 9100. Below link should give you details, I have used this method for HP printers but I believe it will work for other printers.

Maybe the string keyword confused you, as it looks exactly like any other value type declaration, but it is actually an alias to System.String as explained in this question.
Also the dark blue color in Visual Studio and the lowercase first letter may mislead into thinking it is a struct.

As Jordan already said you have to post back the javascript variable to your server before the server can handle the value. To do this you can either program a javascript function that submits a form - or you can use ajax / jquery. jQuery.post

Maybe the most easiest approach for you is something like this

function myJavascriptFunction() { 
  var javascriptVariable = "John";
  window.location.href = "myphpfile.php?name=" + javascriptVariable; 
}

On your myphpfile.php you can use $_GET['name'] after your javascript was executed.

If your count(distinct(x)) is significantly slower than count(x) then you can speed up this query by maintaining x value counts in different table, for example table_name_x_counts (x integer not null, x_count int not null), using triggers. But your write performance will suffer and if you update multiple x values in single transaction then you'd need to do this in some explicit order to avoid possible deadlock.

There is no portable function that allows to check if a key is hit and continue if not. This is always system dependent.

Solution for linux and other posix compliant systems:

Here, for Morgan Mattews's code provide kbhit() functionality in a way compatible with any POSIX compliant system. He uses the trick of desactivating buffering at termios level.

Solution for windows:

For windows, Microsoft offers _kbhit()

The SELECT WITH (NOLOCK) allows reads of uncommitted data, which is equivalent to having the READ UNCOMMITTED isolation level set on your database. The NOLOCK keyword allows finer grained control than setting the isolation level on the entire database.

Wikipedia has a useful article: Wikipedia: Isolation (database systems)

It is also discussed at length in other stackoverflow articles.

Yes, your conclusion is correct. socket.recv is a blocking call.

socket.recv(1024) will read at most 1024 bytes, blocking if no data is waiting to be read. If you don't read all data, an other call to socket.recv won't block.

socket.recv will also end with an empty string if the connection is closed or there is an error.

If you want a non-blocking socket, you can use the select module (a bit more complicated than just using sockets) or you can use socket.setblocking.

I had issues with socket.setblocking in the past, but feel free to try it if you want.

The standard way is to use atexit.register:

# package.py
import atexit
import os

class Package:
    def __init__(self):
        self.files = []
        atexit.register(self.cleanup)

    def cleanup(self):
        print("Running cleanup...")
        for file in self.files:
            print("Unlinking file: {}".format(file))
            # os.unlink(file)

But you should keep in mind that this will persist all created instances of Package until Python is terminated.

Demo using the code above saved as package.py:

$ python
>>> from package import *
>>> p = Package()
>>> q = Package()
>>> q.files = ['a', 'b', 'c']
>>> quit()
Running cleanup...
Unlinking file: a
Unlinking file: b
Unlinking file: c
Running cleanup...

As an addition and observation to the other useful answers, it's worth noticing that actually doing [:10] as slicing will return the first 10 elements of the list, not the last 10...

To get the last 10 you should do [-10:] instead (see here). This will help you avoid using order_by('-id') with the - to reverse the elements.

To find files accessed 1, 2, or 3 minutes ago use -3

find . -cmin -3

s.length() - s.replaceAll(" ", "").length() returns you number of spaces.

There are more ways. For example"

int spaceCount = 0;
for (char c : str.toCharArray()) {
    if (c == ' ') {
         spaceCount++;
    }
}

etc., etc.

In your case you tried to split string using \t - TAB. You will get right result if you use " " instead. Using \s may be confusing since it matches all whitepsaces - regular spaces and TABs.

The above answer only adds the sqljdbc4.jar to the local repository. As a result, when creating the final project jar for distribution, sqljdbc4 will again be missing as was indicated in the comment by @Tony regarding runtime error.

Microsoft (and Oracle and other third party providers) restrict the distribution of their software as per the ENU/EULA. Therefore those software modules do not get added in Maven produced jars for distribution. There are hacks to get around it (such as providing the location of the 3rd party jar file at runtime), but as a developer you must be careful about violating the licensing.

A better approach for jdbc connectors/drivers is to use jTDS, which is compatible to most DBMS's, more reliable, faster (as per benchmarks), and distributed under GNU license. It will make your life much easier to use this than trying to pound the square peg into the round hole following any of the other techniques above.

In Visual Studio 2005 Pro:

Ctrl + E, Ctrl + W

Or menu Edit ? Advanced ? Word Wrap.

it was hard to solve but i did it look go to C:\Users\Vinnie\ delete .gradle file its you didn't see it it may be in hidden files so if you use windows 7 right click then click on properties and click on hidden to be not checked

then the file will appear then delete it i hope this works

This stuff comes from ES file explorer

Just go into this app > settings

Then there is an option that says logging floating window, you just need to disable that and you will get rid of this infernal bubble for good

From http://social.msdn.microsoft.com/Forums/vstudio/en-US/12ead5d4-1d57-4dbb-ba81-bc13084ba370/how-can-i-add-a-line-as-a-visual-separator-to-the-content-control-like-grid?forum=wpf:

Try this example and see if it fits your needs, there are three main aspects to it.

1. Line.Stretch is set to fill.

2. For horizontal lines the VerticalAlignment of the line is set Bottom, and for VerticalLines the HorizontalAlignment is set to Right.

3. We then need to tell the line how many rows or columns to span, this is done by binding to either RowDefinitions or ColumnDefintions count property.

   
   
   

       <Style x:Key="horizontalLineStyle" TargetType="Line" BasedOn="{StaticResource lineStyle}">  
           <Setter Property="X2" Value="1" /> 
           <Setter Property="VerticalAlignment" Value="Bottom" /> 
           <Setter Property="Grid.ColumnSpan" 
                   Value="{Binding   
                               Path=ColumnDefinitions.Count,  
                               RelativeSource={RelativeSource AncestorType=Grid}}"/> 
       </Style> 
   
       <Style x:Key="verticalLineStyle" TargetType="Line" BasedOn="{StaticResource lineStyle}">  
           <Setter Property="Y2" Value="1" /> 
           <Setter Property="HorizontalAlignment" Value="Right" /> 
           <Setter Property="Grid.RowSpan"   
                   Value="{Binding   
                               Path=RowDefinitions.Count,  
                               RelativeSource={RelativeSource AncestorType=Grid}}"/> 
       </Style> 
   </Grid.Resources>        
   
   <Grid.RowDefinitions> 
       <RowDefinition Height="20"/>  
       <RowDefinition Height="20"/>  
       <RowDefinition Height="20"/>  
       <RowDefinition Height="20"/>  
   </Grid.RowDefinitions> 
   
   <Grid.ColumnDefinitions> 
       <ColumnDefinition Width="20"/>  
       <ColumnDefinition Width="20"/>  
       <ColumnDefinition Width="20"/>  
       <ColumnDefinition Width="20"/>  
   </Grid.ColumnDefinitions> 
   
   <Line Grid.Column="0" Style="{StaticResource verticalLineStyle}"/>  
   <Line Grid.Column="1" Style="{StaticResource verticalLineStyle}"/>  
   <Line Grid.Column="2" Style="{StaticResource verticalLineStyle}"/>  
   <Line Grid.Column="3" Style="{StaticResource verticalLineStyle}"/>  
   
   <Line Grid.Row="0" Style="{StaticResource horizontalLineStyle}"/>  
   <Line Grid.Row="1" Style="{StaticResource horizontalLineStyle}"/>  
   <Line Grid.Row="2" Style="{StaticResource horizontalLineStyle}"/>  
   <Line Grid.Row="3" Style="{StaticResource horizontalLineStyle}"/>  
   

I used withStyles instead of makeStyle

EX :

import { withStyles } from '@material-ui/core/styles';
import React, {Component} from "react";

const useStyles = theme => ({
        root: {
           flexGrow: 1,
         },
  });

class App extends Component {
       render() {
                const { classes } = this.props;
                return(
                    <div className={classes.root}>
                       Test
                </div>
                )
          }
} 

export default withStyles(useStyles)(App)

It's your "fault" in that that's how Or is defined, so it's the behaviour you should expect:

In a Boolean comparison, the Or operator always evaluates both expressions, which could include making procedure calls. The OrElse Operator (Visual Basic) performs short-circuiting, which means that if expression1 is True, then expression2 is not evaluated.

But you don't have to endure it. You can use OrElse to get short-circuiting behaviour.

So you probably want:

If (example Is Nothing OrElse Not example.Item = compare.Item) Then
    'Proceed
End If

I can't say it reads terribly nicely, but it should work...

Tried this on firefox, works http://jsfiddle.net/Tm26Q/1/

$(function(){
 /** Just to mimic a blinking box on the page**/
  setInterval(function(){$("div#box").hide();},2001);
  setInterval(function(){$("div#box").show();},1000);
 /**/
});

$("div#box").on("DOMAttrModified",
function(){if($(this).is(":visible"))console.log("visible");});

UPDATE

Currently the Mutation Events (like DOMAttrModified used in the solution) are replaced by MutationObserver, You can use that to detect DOM node changes like in the above case.

For anyone who is looking a way to watch a specific file to exist in VBS:

Function bIsFileDownloaded(strPath, timeout)
  Dim FSO, fileIsDownloaded
  set FSO = CreateObject("Scripting.FileSystemObject")
  fileIsDownloaded = false
  limit = DateAdd("s", timeout, Now)
  Do While Now < limit
    If FSO.FileExists(strPath) Then : fileIsDownloaded = True : Exit Do : End If
    WScript.Sleep 1000      
  Loop
  Set FSO = Nothing
  bIsFileDownloaded = fileIsDownloaded
End Function

Usage:

FileName = "C:\test.txt"
fileIsDownloaded = bIsFileDownloaded(FileName, 5) ' keep watching for 5 seconds

If fileIsDownloaded Then
  WScript.Echo Now & " File is Downloaded: " & FileName
Else
  WScript.Echo Now & " Timeout, file not found: " & FileName 
End If

Unfortunately, git branch -a and git branch -r do not show you all remote branches, if you haven't executed a "git fetch".

git remote show origin works consistently all the time. Also git show-ref shows all references in the Git repository. However, it works just like the git branch command.

The process of Abstraction and Encapsulation both generate interfaces.

An interface generated via encapsulation hides implementation details.

An interface generated via abstraction becomes applicable to more data types, compared to before abstraction.

A solution I prefer would be:

const str = 'sometext-20202';
const slug = str.split('-').pop();

Where slug would be your result

I wanted to show how powerful it can be aside from just checking "-lt".

Example: I used it to calculate time differences take from Windows event view Application log:

Get the difference between the two date times:

PS> $Obj = ((get-date "10/22/2020 12:51:1") - (get-date "10/22/2020 12:20:1 "))

Object created:

PS> $Obj


Days              : 0
Hours             : 0
Minutes           : 31

As wikipedia says, Median-of-Medians is theoretically o(N), but it is not used in practice because the overhead of finding "good" pivots makes it too slow.
http://en.wikipedia.org/wiki/Selection_algorithm

Here is Java source for a Quickselect algorithm to find the k'th element in an array:

/**
 * Returns position of k'th largest element of sub-list.
 * 
 * @param list list to search, whose sub-list may be shuffled before
 *            returning
 * @param lo first element of sub-list in list
 * @param hi just after last element of sub-list in list
 * @param k
 * @return position of k'th largest element of (possibly shuffled) sub-list.
 */
static int select(double[] list, int lo, int hi, int k) {
    int n = hi - lo;
    if (n < 2)
        return lo;

    double pivot = list[lo + (k * 7919) % n]; // Pick a random pivot

    // Triage list to [<pivot][=pivot][>pivot]
    int nLess = 0, nSame = 0, nMore = 0;
    int lo3 = lo;
    int hi3 = hi;
    while (lo3 < hi3) {
        double e = list[lo3];
        int cmp = compare(e, pivot);
        if (cmp < 0) {
            nLess++;
            lo3++;
        } else if (cmp > 0) {
            swap(list, lo3, --hi3);
            if (nSame > 0)
                swap(list, hi3, hi3 + nSame);
            nMore++;
        } else {
            nSame++;
            swap(list, lo3, --hi3);
        }
    }
    assert (nSame > 0);
    assert (nLess + nSame + nMore == n);
    assert (list[lo + nLess] == pivot);
    assert (list[hi - nMore - 1] == pivot);
    if (k >= n - nMore)
        return select(list, hi - nMore, hi, k - nLess - nSame);
    else if (k < nLess)
        return select(list, lo, lo + nLess, k);
    return lo + k;
}

I have not included the source of the compare and swap methods, so it's easy to change the code to work with Object[] instead of double[].

In practice, you can expect the above code to be o(N).

It appears Microsoft now stores them in a SQLite database file called plum.sqlite located here:

C:\Users\%username%\AppData\Local\Packages\Microsoft.MicrosoftStickyNotes_8wekyb3d8bbwe\LocalState\plum.sqlite

Unfortunatelly, today (September 2018) you can not find cross-browser solution for client side file writing.

For example: in some browser like a Chrome we have today this possibility and we can write with FileSystemFileEntry.createWriter() with client side call, but according to the docu:

This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

---

For IE (but not MS Edge) we could use ActiveX too, but this is only for this client.

If you want update your JSON file cross-browser you have to use server and client side together.

The client side script

On client side you can make a request to the server and then you have to read the response from server. Or you could read a file with FileReader too. For the cross-browser writing to the file you have to have some server (see below on server part).

var xhr = new XMLHttpRequest(),
    jsonArr,
    method = "GET",
    jsonRequestURL = "SOME_PATH/jsonFile/";

xhr.open(method, jsonRequestURL, true);
xhr.onreadystatechange = function()
{
    if(xhr.readyState == 4 && xhr.status == 200)
    {
        // we convert your JSON into JavaScript object
        jsonArr = JSON.parse(xhr.responseText);

        // we add new value:
        jsonArr.push({"nissan": "sentra", "color": "green"});

        // we send with new request the updated JSON file to the server:
        xhr.open("POST", jsonRequestURL, true);
        xhr.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
        // if you want to handle the POST response write (in this case you do not need it):
        // xhr.onreadystatechange = function(){ /* handle POST response */ };
        xhr.send("jsonTxt="+JSON.stringify(jsonArr));
        // but on this place you have to have a server for write updated JSON to the file
    }
};
xhr.send(null);

Server side scripts

You can use a lot of different servers, but I would like to write about PHP and Node.js servers.

By using searching machine you could find "free PHP Web Hosting*" or "free Node.js Web Hosting". For PHP server I would recommend 000webhost.com and for Node.js I would recommend to see and to read this list.

PHP server side script solution

The PHP script for reading and writing from JSON file:

<?php

// This PHP script must be in "SOME_PATH/jsonFile/index.php"

$file = 'jsonFile.txt';

if($_SERVER['REQUEST_METHOD'] === 'POST')
// or if(!empty($_POST))
{
    file_put_contents($file, $_POST["jsonTxt"]);
    //may be some error handeling if you want
}
else if($_SERVER['REQUEST_METHOD'] === 'GET')
// or else if(!empty($_GET))
{
    echo file_get_contents($file);
    //may be some error handeling if you want
}
?>

Node.js server side script solution

I think that Node.js is a little bit complex for beginner. This is not normal JavaScript like in browser. Before you start with Node.js I would recommend to read one from two books:

• Learning Node: Moving to the Server-Side
• Node.js Web Development: Server-side development

The Node.js script for reading and writing from JSON file:

var http = require("http"),
    fs = require("fs"),
    port = 8080,
    pathToJSONFile = '/SOME_PATH/jsonFile.txt';

http.createServer(function(request, response)
{
    if(request.method == 'GET')
    {
        response.writeHead(200, {"Content-Type": "application/json"});
        response.write(fs.readFile(pathToJSONFile, 'utf8'));
        response.end();
    }
    else if(request.method == 'POST')
    {
        var body = [];

        request.on('data', function(chunk)
        {
            body.push(chunk);
        });

        request.on('end', function()
        {
            body = Buffer.concat(body).toString();
            var myJSONdata = body.split("=")[1];
            fs.writeFileSync(pathToJSONFile, myJSONdata); //default: 'utf8'
        });
    }
}).listen(port);

System.Environment.ExitCode 

http://msdn.microsoft.com/en-us/library/system.environment.exitcode.aspx

answering to your question:

How can I destroy or unset the value of the session?

I can help you by this:

$this->session->unset_userdata('some_name');

and for multiple data you can:

$array_items = array('username' => '', 'email' => '');

$this->session->unset_userdata($array_items);

and to destroy the session:

$this->session->sess_destroy();

Now for the on page change part (on the top of my mind):

you can set the config "anchor_class" of the paginator equal to the classname you want.

after that just check it with jquery onclick for that class which will send a head up to the controller function that will unset the user session.

The fragment identifier (also known as: Fragment IDs, Anchor Identifiers, Named Anchors) introduced by a hash mark # is the optional last part of a URL for a document. It is typically used to identify a portion of that document.

<a href="http://www.someuri.com/page#fragment">Link to fragment identifier</a>

Syntax for URIs also allows an optional query part introduced by a question mark ?. In URIs with a query and a fragment the fragment follows the query.

<a href="http://www.someuri.com/page?query=1#fragment">Link to fragment with a query</a>

When a Web browser requests a resource from a Web server, the agent sends the URI to the server, but does not send the fragment. Instead, the agent waits for the server to send the resource, and then the agent (Web browser) processes the resource according to the document type and fragment value.

Named Anchors <a name="fragment"> are deprecated in XHTML 1.0, the ID attribute is the suggested replacement. <div id="fragment"></div>

One option is to use do.call():

OAuth(Open Authorization) is an open standard for access granting/deligation protocol. It used as a way for Internet users to grant websites or applications access to their information on other websites but without giving them the passwords. It does not deal with authentication.

Or

OAuth 2.0 is a protocol that allows a user to grant limited access to their resources on one site, to another site, without having to expose their credentials.

• Analogy 1: Many luxury cars today come with a valet key. It is a special key you give the parking attendant and unlike your regular key, will not allow the car to drive more than a mile or two. Some valet keys will not open the trunk, while others will block access to your onboard cell phone address book. Regardless of what restrictions the valet key imposes, the idea is very clever. You give someone limited access to your car with a special key, while using your regular key to unlock everything. src from auth0

• Analogy 2: Assume, we want to fill an application form for a bank account. Here Oauth works as, instead of filling the form by applicant, bank can fill the form using Adhaar or passport.

  Here the following three entities are involved:

  1. Applicant i.e. Owner
  2. Bank Account is OAuth Client, they need information
  3. Adhaar/Passport ID is OAuth Provider

I had the same problem :) Verify the "Source code" folder on the "Solution Explorer", if it doesn't contain any "source code" file then :

Right click on "Source code" > Add > Existing Item > Choose the file You want to build and run.

Good luck ;)

To fix the issue

Pressing ctrl+M causes the ? Tab key to move focus instead of inserting a ? Tab character.
Turn it off by pressing the shortcut again.

To disable the shortcut

1. Open "Keyboard Shortcuts" with ctrl+K, then ctrl+S.
   Or go to File > Preferences > Keyboard Shortcuts.
2. Search for toggle tab key moves focus.
3. Right Click, Remove Keybinding.

instead of os.walk, just use os.listdir

I just dealt with this. Depending on what you really want, you can get the details from the order like this:

$field = get_post_meta($order->id, $field_name, true);

Where $field_name is '_billing_address_1' or '_shipping_address_1'or 'first_name'. You can google the other fields, but don't forget the "" at the beginning.

If you want to retrieve the customer for this order, and get its field directly, it works as in your solution, except you do not need to retrieve the full customer object:

$customer_id = (int)$order->user_id;

$field = get_user_meta($customer_id, $field_name, true);

Now in this case, the $field_name does not start with "_". For example: 'first_name' and 'billing_address_1'.

Sorry not sure what was going on this worked in the end:

<VirtualHost *> 
    ServerName example.com
    DocumentRoot /var/www/html/mjp

    Alias /ncn "/var/www/html/ncn"

    <Directory "/var/www/html/ncn">
        Options None
        AllowOverride None
        Order allow,deny
        Allow from all
    </Directory>
</VirtualHost>

If you want it one time & let system handle the rest (not dynamic) then do like this in your manifest file:

<application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name_full" > //This is my custom title name on activity. <- The question is about this one.
            <intent-filter android:label="@string/app_launcher_name" > //This is my custom Icon title name (launcher name that you see in android apps/homescreen)
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

Simple:

$this->getDoctrine()->getRepository('AcmeBundle:User')->findBy(
    array(),
    array('username' => 'ASC')
);

I found another solution which you can convert it to whatever format you want and apply to all LocalDateTime datatype and you do not have to specify @JsonFormat above every LocalDateTime datatype. first add the dependency :

<dependency>
    <groupId>com.fasterxml.jackson.datatype</groupId>
    <artifactId>jackson-datatype-jsr310</artifactId>
</dependency>

Add the following bean :

@Configuration
public class Java8DateTimeConfiguration {
    /**
     * Customizing
     * http://docs.spring.io/spring-boot/docs/current/reference/html/howto-spring-mvc.html
     *
     * Defining a @Bean of type Jackson2ObjectMapperBuilder will allow you to customize both default ObjectMapper and XmlMapper (used in MappingJackson2HttpMessageConverter and MappingJackson2XmlHttpMessageConverter respectively).
     */
    @Bean
    public Module jsonMapperJava8DateTimeModule() {
        val bean = new SimpleModule();

        bean.addDeserializer (ZonedDateTime.class, new JsonDeserializer<ZonedDateTime>() {
            @Override
            public ZonedDateTime deserialize(JsonParser jsonParser, DeserializationContext deserializationContext) throws IOException, JsonProcessingException {
                return ZonedDateTime.parse(jsonParser.getValueAsString(), DateTimeFormatter.ISO_ZONED_DATE_TIME);
            }
        });

        bean.addDeserializer(LocalDateTime.class, new JsonDeserializer<LocalDateTime>() {
            @Override
            public LocalDateTime deserialize(JsonParser jsonParser, DeserializationContext deserializationContext) throws IOException, JsonProcessingException {
                return LocalDateTime.parse(jsonParser.getValueAsString(), DateTimeFormatter.ISO_LOCAL_DATE_TIME);
            }
        });

        bean.addSerializer(ZonedDateTime.class, new JsonSerializer<ZonedDateTime>() {
            @Override
            public void serialize(
                    ZonedDateTime zonedDateTime, JsonGenerator jsonGenerator, SerializerProvider serializerProvider)
                    throws IOException {
                jsonGenerator.writeString(DateTimeFormatter.ISO_ZONED_DATE_TIME.format(zonedDateTime));
            }
        });

        bean.addSerializer(LocalDateTime.class, new JsonSerializer<LocalDateTime>() {
            @Override
            public void serialize(
                    LocalDateTime localDateTime, JsonGenerator jsonGenerator, SerializerProvider serializerProvider)
                    throws IOException {
                jsonGenerator.writeString(DateTimeFormatter.ISO_LOCAL_DATE_TIME.format(localDateTime));
            }
        });

        return bean;
    }
}

in your config file add the following :

@Import(Java8DateTimeConfiguration.class)

This will serialize and de-serialize all properties LocalDateTime and ZonedDateTime as long as you are using objectMapper created by spring.

The format that you got for ZonedDateTime is : "2017-12-27T08:55:17.317+02:00[Asia/Jerusalem]" for LocalDateTime is : "2017-12-27T09:05:30.523"

If that message is bother you, You need run Visual Studio with administrative rights to apply this direction on Visual Studio.

Tools-> Options-> Debugging-> Symbols and select check in a box "Microsoft Symbol Servers", mark load all modules then click Load all Symbols.

Everything else Visual Studio will do it for you, and you will have this message under Debug in Output window "Native' has exited with code 0 (0x0)"

I don't know about methods; however, the type to GUID can be done via:

Guid iid = System.Runtime.InteropServices.Marshal.GenerateGuidForType(typeof(IFoo));

http://msdn.microsoft.com/en-us/library/system.runtime.interopservices.marshal.generateguidfortype.aspx

import win32com.client as win32
outlook = win32.Dispatch('outlook.application')
mail = outlook.CreateItem(0)
mail.To = 'To address'
mail.Subject = 'Message subject'
mail.Body = 'Message body'
mail.HTMLBody = '<h2>HTML Message body</h2>' #this field is optional

# To attach a file to the email (optional):
attachment  = "Path to the attachment"
mail.Attachments.Add(attachment)

mail.Send()

Will use your local outlook account to send.

Note if you are trying to do something not mentioned above, look at the COM docs properties/methods: https://msdn.microsoft.com/en-us/vba/outlook-vba/articles/mailitem-object-outlook. In the code above, mail is a MailItem Object.

document.getScroll = function() {
    if (window.pageYOffset != undefined) {
        return [pageXOffset, pageYOffset];
    } else {
        var sx, sy, d = document,
            r = d.documentElement,
            b = d.body;
        sx = r.scrollLeft || b.scrollLeft || 0;
        sy = r.scrollTop || b.scrollTop || 0;
        return [sx, sy];
    }
}

returns an array with two integers- [scrollLeft, scrollTop]

The easiest way I find is to create a file "any_name.pth" and put it in your folder "\Lib\site-packages". You should find that folder wherever python is installed.

In that file, put a list of directories where you want to keep modules for importing. For instance, make a line in that file like this:

C:\Users\example...\example

You will be able to tell it works by running this in python:

import sys
for line in sys: print line

You will see your directory printed out, amongst others from where you can also import. Now you can import a "mymodule.py" file that sits in that directory as easily as:

import mymodule

This will not import subfolders. For that you could imagine creating a python script to create a .pth file containing all sub folders of a folder you define. Have it run at startup perhaps.

If you're using Rails 3+, remove the gem from the Gemfile and run bundle install.

If you're using Rails 2, hopefully you've put the declaration in config/environment.rb. If so, removing it from there and running rake gems:install should do the trick.

Just Simple Answer. FETCH DELETE

function deleteData(item, url) {
  return fetch(url + '/' + item, {
    method: 'delete'
  })
  .then(response => response.json());
}

Here's yet another way to convert 65 into A (via octal):

help printf  # in Bash
man bash | less -Ip '^[[:blank:]]*printf'

printf "%d\n" '"A'
printf "%d\n" "'A"

printf '%b\n' "$(printf '\%03o' 65)"

To search in man bash for \' use (though futile in this case):

man bash | less -Ip "\\\'"  # press <n> to go through the matches

I happened to walk across this question looking for something similar. It gave me enough info to run a test to get the answer I wanted. So if anyone else wants to know how to dynamically add to or lookup a {key: 'value'} pair in a JavaScript object, this test should tell you all you might need to know.

var dictionary = {initialkey: 'initialValue'};
var key = 'something';
var key2 =  'somethingElse';
var value = 'value1';
var value2 = 'value2';
var keyInitial = 'initialkey';

console.log(dictionary[keyInitial]);

dictionary[key] =value;
dictionary[key2] = value2;
console.log(dictionary);

output

initialValue
{ initialkey: 'initialValue',
  something: 'value1',
  somethingElse: 'value2' }

In this case no conditionals are needed to set the variable.

This one-liner XPath expression:

boolean(joined-subclass)

is true() only when the child of the current node, named joined-subclass exists and it is false() otherwise.

The complete stylesheet is:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes"/>

 <xsl:template match="class">
   <xsl:variable name="subexists"
        select="boolean(joined-subclass)"
   />

   subexists:  <xsl:text/>
   <xsl:value-of select="$subexists" />
 </xsl:template>
</xsl:stylesheet>

Do note, that the use of the XPath function boolean() in this expression is to convert a node (or its absense) to one of the boolean values true() or false().

Here is a more complex "not in" query, using a subquery in rails 4 using squeel. Of course very slow compared to the equivalent sql, but hey, it works.

    scope :translations_not_in_english, ->(calmapp_version_id, language_iso_code){
      join_to_cavs_tls_arr(calmapp_version_id).
      joins_to_tl_arr.
      where{ tl1.iso_code == 'en' }.
      where{ cavtl1.calmapp_version_id == my{calmapp_version_id}}.
      where{ dot_key_code << (Translation.
        join_to_cavs_tls_arr(calmapp_version_id).
        joins_to_tl_arr.    
        where{ tl1.iso_code == my{language_iso_code} }.
        select{ "dot_key_code" }.all)}
    }

The first 2 methods in the scope are other scopes which declare the aliases cavtl1 and tl1. << is the not in operator in squeel.

Hope this helps someone.

you can do it by changing $q to this:

$q="SELECT * FROM projects WHERE YEAR(date) = $year_v AND MONTH(date) = $month_v;

If you want to filter out records having None value in column then see below example:

df=spark.createDataFrame([[123,"abc"],[234,"fre"],[345,None]],["a","b"])

Now filter out null value records:

df=df.filter(df.b.isNotNull())

df.show()

If you want to remove those records from DF then see below:

df1=df.na.drop(subset=['b'])

df1.show()

Swift

Updated for Swift 3

// current date and time
let someDate = Date()

// time interval since 1970
let myTimeStamp = someDate.timeIntervalSince1970

Notes

• timeIntervalSince1970 returns TimeInterval, which is a typealias for Double.

• If you wanted to go the other way you could do the following:

    let myDate = Date(timeIntervalSince1970: myTimeStamp)
  

So, the question now is how do we prefill the textarea element ? XYZ, you'll get:

The main problem is that in the textarea element we're unintentionally prefilling the element by white space.

Very simple way to do this---

In your Activity--

 TextView tv = (TextView) findViewById(R.id.site);
 tv.setText(Html.fromHtml("<a href=http://www.stackoverflow.com> STACK OVERFLOW "));
 tv.setMovementMethod(LinkMovementMethod.getInstance());

Then you will get just the Tag, not the whole link..

Hope it will help you...

Try this lets say your form id is formID

$(".nextbutton").click(function() { $("form#formID").submit(); });

I just had this issue from a namespace mismatch. My XAML file was getting ported over and it had a different namespace from that in the code behind file.

For me the problem was that Visual Studio was opened when performing the command

git checkout <file>

After closing Visual Studio the command worked and I could finally apply my work from the stack. So check all applications that could make changes to your code, for example SourceTree, SmartGit, NotePad, NotePad++ and other editors.

Adding this here because the more relevant questions have all been marked as duplicates pointing here…

My situation is simpler:

• user clicks the link (a[href='#something'])
• click handler does: e.preventDefault()
• smoothscroll function: $("html,body").stop(true,true).animate({ "scrollTop": linkoffset.top }, scrollspeed, "swing" );
• then window.location = link;

This way, the scroll occurs, and there's no jump when the location is updated.
